[109] The dust bag 193 is formed of a material that allows air to pass through, blocking foreign substances, so that foreign substances discharged from the dust collection container 15 into the collection chamber 190 can be collected.

[110] The dust bag 193 may be provided in the suction flow path 441, and the dust bag 193 may be provided separately from the collection chamber 190.

[111] When the discharge station 100 is operated and foreign matter is collected in the dust bag 193, the user separates the panel 104 and opens the collection cover 192, separating the dust bag 193 from the collection 190 so that the foreign matter collected in the discharge station 100 is discharged .

[112] The suction device 150 includes a suction fan 153, a first motor 151 for rotating the suction fan 153, and a suction device body 106 defining an internal space in which the suction fan 153 is located.

[113] The suction device housing 106 may include a suction device cover 107, which is located on the housing 101 and opens and closes the interior of the suction device 150. The suction device cover 107 may be configured to discharge air sucked by the suction fan 153.

[114] The suction air flow generated by the suction fan 153 may be supplied to the collection 190 through the suction flow path 180 in the interior of the suction device housing 106, and then to the dust collection container 15.

[115] As described above, the suction device 150 can supply suction air flow to the dust collection container 15 by rotating the suction fan 153, and the air directed by the suction fan 153 can be moved from the dust collection container 15 into the collection container, ultimately moving to the outside of the station 100 unloading

[116] The discharge station 100 may further include a flow control device 160 configured to selectively change the amount of suction air flow supplied to the dust collection container 15 in accordance with an embodiment. The flow control device 160 may include a flow path valve 163 configured to open or close the suction flow path 180, and a second motor 161 that provides power to the flow path valve 163.

[117] The flow control device 160 may be located inside the housing 101. The flow control device 160 may be located between the collector 190 and the suction device 150. In detail, the flow channel valve 163 may be located in the middle of the connecting flow channel (suction flow channel) 180 connecting a collector 190 with a suction device 150 and ensuring the flow of air in it. However, the disclosure is not limited to this, and the flow channel valve 163 may be provided located in the middle of the connecting flow channel (suction flow channel) 180 connecting the reservoir 190 and the installation portion 181.

[118] That is, the flow path valve 163 can open and close the suction flow path 180 based on the power supplied by the second motor 161. For this purpose, the flow path valve 163 180 can be provided in the suction flow path 180.

[119] For example, the flow channel valve 163 may include a body provided in the form of a plate and configured to reciprocate in one direction, and may be configured to open and close the suction flow channel 180 due to the reciprocating movement this body.

[120] In addition, the flow channel valve 163 may include a cylindrical shape rotatable about a central axis, a body providing the cylindrical shape, and slotted portions formed by cutting both sides of the body around the central side, and when the body and the slotted portions are rotated on the central axis, the suction flow path 180 is opened and closed.

[121] However, the type of flow path valve 163 is not limited to the above example, and the size of the flow path 165 can be implemented without limitation as long as it can open and close the suction flow path 180 based on the power transmitted from the second motor 161.

[122] The design characteristics of the cleaning device 1 have been described in detail above. The following description will be made regarding the control configuration for irregular supply of suction air flow to the dust collection container 15 connected to the discharge station 100.

[123] FIG. 5 is a control block diagram showing an unloading station 100 in accordance with an embodiment of the disclosure.

[124] Referring to FIG. 5, the discharge station 100 according to an embodiment includes a sensor 110 for determining whether the dust collection container 15 is connected to the discharge station 100, an input device 120 for receiving input from a user, a position determining sensor 130 for determining the position of the flow path valve 163 of the flow control device 160, a collection sensor 195 for determining whether the collection container 190 is in a full state, a controller 140 for controlling the suction device 150 and the flow control device 160 for supplying uneven suction air flow to the dust collection container 15, wherein The suction device 150 includes a first motor 151 and a suction fan 153 and generates a suction air flow to be supplied to the dust collection container 15, wherein the flow control device 160 includes a second motor 161 and a flow path valve 163 for opening and closing the suction path 180. flow and adjusting the flow rate of the suction air flow to be supplied to the dust collection container 15, a display device 170 on which the operating status is displayed, and an ultraviolet irradiator 185 for irradiating the dust collection container 15 or collection 190 with ultraviolet rays.

[125] However, some components of the unloading station 100 shown in FIG. 5 may be omitted in accordance with an embodiment, and the unloading station 100 may further include other components in addition to the components shown in FIG. 5 (e.g., A storage device that stores various pieces of information, such as flash memory, random access memory (RAM), and hard disk drive (HDD).

[126] The sensor 110 according to an embodiment can determine whether the dust collection container 15 is connected to the discharge station 100.

[127] For this purpose, the sensor 110 may be located at one end of the suction flow path 180 to which the dust collection container 15 is connected, and the output (output flow) for the case in which the dust collection container 15 is connected to the discharge station 100 may be different from the output for the case in which the dust collection container 15 is not connected to the discharge station 100. Specifically, the dust collection container 15 may be installed at one end of the mounting portion 181.

[128] For example, the sensor 110 may be, but is not limited to, an infrared sensor, a piezoelectric sensor, or the like. The sensor may be configured in various ways without limitation, as long as it can change output values depending on whether the dust collection container 15 is connected to the discharge station 100.

[129] The input device 120 according to an embodiment can receive input from a user.

[130] For this purpose, the input device 120 may be located on the housing 101 of the unloading station 100 and may be implemented using a mechanical button, switch, knob, touch panel, and the like.

[131] For example, the input device 120 may be provided on the upper side of the discharge station 100 and may be configured as a button or switch. However, the location and type of input device 120 is not limited as long as it can receive user input.

[132] Specifically, the input device 120 can receive an action command and a stop command from the user in the operation of removing foreign substances from the dust collection container 15. In addition, the input device 120 can receive action commands for various modes, such as a suction mode, a displays or the like, in accordance with an embodiment.

[133] The position detection sensor 130 in accordance with an embodiment can determine the position of the flow control device 160 .

[134] In detail, the position detection sensor 130 can determine whether the flow channel valve 163 of the flow control device 160 is in a position in which the flow channel valve 163 closes the suction flow path 180 or in a position in which the flow channel valve 163 closes the channel 180 suction flow.

[135] For example, the position detection sensor 130 may be provided as a microswitch that is pressed in accordance with the movement of the flow path valve 163, outputting a first value when the flow path valve 163 closes the suction flow path 180, and outputting a second value when the valve 163 the flow channel opens the suction flow channel 180.

[136] However, the position detecting sensor 130 is not limited to the above example, and the position detecting sensor 130 may be provided as a motor position sensor configured to sense the position of the second motor 161 that supplies power to the flow channel valve 163, outputting a first value when the valve The flow channel 163 closes the suction flow channel 180, and outputs a second value when the flow channel valve 163 opens the suction flow channel 180. In this case, the position sensor 130 may detect the position of the rotor included in the second motor 161, and for this purpose may be provided on a surface facing the rotating shaft of the second motor 161. For example, the position sensor 130 may correspond to a Hall sensor using the Hall effect , but is not limited to this, and the position detection sensor 130 may be provided in various ways without limitation as long as it can change the output signal in accordance with the rotation of the motor.

[137] The controller 140 according to an embodiment can control the suction device 150 so that foreign matter from the dust collection container 15 is discharged into the discharge station 100 when the dust collection container 15 is connected to the discharge station 100.

[138] In detail, the controller 140 can determine whether the dust collection container 15 is connected to the unloading station 100 based on the output value of the sensor 110, and when the dust collection container 15 is connected to the unloading station 100, control the start of operation of the first motor 151.

[139] However, the controller 140 may additionally take into account the user action command entered through the input device 120 in addition to the output value of the sensor 110, controlling the initiation of an operation only when there is an action command from the user.

[140] In this case, when the first motor 151 is kept turned on and the same suction air flow is supplied to the dust collection container 15, some foreign substances may be caught in the internal components of the dust collection container 15 and may not be discharged to the outside. For example, foreign matter such as hair may be caught by the internal structure of the dust collection container 15 and, despite the suction air flow, may remain inside the dust collection container 15 without being separated to the outside of the dust collection container 15. That is, the suction air flow supplied to the interior of the dust collection container 15 , can only be formed in one and the same direction. Accordingly, some foreign substances may have resistance in the direction in which the suction air flow is generated, and thus may not be separated to the outside of the dust collection container 15 under the action of the suction air flow. Thus, foreign substances inside the dust collection container 15 cannot be discharged effectively.

[141] The discharge station 100 according to the embodiment, while the suction air flow is supplied to the dust collection container 15 by the suction fan 153 and the air from the dust collection container 15 is sucked, makes it possible to change the suction air flow, thereby changing the air flow rate inside the dust collection container. container 15 and varying the air flow inside the dust collection container 15.

[142] The controller 140, in order to create an uneven suction air flow in the dust collection container 15, can control the flow control device 160 by periodically opening and closing the suction flow path 180 during operation of the suction device 150 (i.e., when the first motor 151 supported enabled).

[143] In this case, the controller 140 can continuously supply voltage to the first motor 151 so that the suction device 150 operates, and while the suction device 150 is operating, the controller 140 can continuously supply voltage even to the second motor 161 of the flow control device 160.

[144] With this configuration, the suction device 150 can continuously generate suction air flow by the suction fan 153, and the flow control device 160 can periodically open and close the suction flow path 180, so that the flow rate of the suction air flow generated by the suction device 150 periodically changes .

[145] Since the direction of the air flow changes instantaneously, some foreign matter having resistance in a particular direction may lose resistance due to the passage of air in another direction, and thus may be thrown out of the dust collection container 15 along with the air flow.

[146] In this case, the foreign substances separated and discharged from the dust collection container 15 can be moved with the air by the suction fan 153 and then collected by the collector 190 provided in the suction flow path 180.

[147] That is, the controller 140 may cause the suction flow path 180 to be periodically opened and closed by the flow control device 160 so that the air flow inside the dust collection container 15 changes. With this configuration, foreign substances from the dust collection container 15 can be discharged more efficiently.

[148] An embodiment in which the suction flow path 180 is periodically opened and closed by the flow control device 160 during continuous operation of the suction device 150 (first motor 151) to remove foreign substances from the dust collection container 15 will be described below.

[149] In addition, the controller 140 according to an embodiment, in order to supply the dust collection container 15 with an irregular suction air flow, can adjust at least one of the driving time or the rotation speed of the first motor 151 when the first motor 151 is repeatedly turned on/off motor 151 suction device 150.

[150] That is, the controller 140 can control the first motor 151 so that the first motor 151 is turned on and off repeatedly.

[151] In this case, the controller 140 adjusts at least one of the time during which the first motor 151 is turned on or the time during which the engine 150 is turned off whenever the first engine 151 is alternately turned on and off, thereby adjusting the time operation of the first engine 151.

[152] In addition, the controller 140 may adjust the duration of a power supply voltage pulse supplied to the first motor 151 whenever the first motor 151 is alternately turned on and off, thereby adjusting the rotation speed of the first motor 151.

[153] In this case, the suction fan 153 can provide suction air flow having different suction power whenever the first motor 151 is alternately turned on and off according to a change in the driving time of the first motor 151 or the rotation speed of the first motor 151, and since the internal pressure of the dust collection container 15 changes due to the uneven suction air flow, foreign substances in the dust collection container 15 can be smoothly discharged from the dust collection container 15.

[154] That is, since the air flow rate inside the dust collection container 15 changes, the air spreads in all directions in the space inside the dust collection container 15, and accordingly, the air flow inside the dust collection container 15 may change in various directions.

[155] Since the direction of the air flow changes instantaneously, some foreign matter having resistance in a particular direction may lose resistance due to the air flow in another direction, and may be thrown out of the dust collection container 15 along with the air flow.

[156] In this case, foreign substances separated from the dust collection container 15 and discharged can be transported with the air when the suction fan 153 is driven and collected in the collector 190 provided in the suction flow path 180.

[157] That is, the controller 140 can repeat the supply and stop of the suction air flow towards the dust collection container 15 by controlling the on-off control of the first motor 151, and changes the supply time or suction power while supplying the suction air flow, thereby periodically changing the air flow inside dust collection container 15. With this configuration, foreign substances from the dust collection container 15 can be discharged more efficiently.

[158] In addition, the controller 140 in accordance with the embodiment may set different durations of the power supply voltage pulses within at least one of the time periods in which the first motor 151 is turned on and off, such that the first motor 151 vibrates.

[159] That is, the controller 140 sets power supply voltage pulse widths that differ from each other during the turn-on time in which the first motor 151 is turned on when voltage is applied, and provides the first motor 151 with the predetermined pulse widths.

[160] For example, controller 140 may adjust the widths of the power supply voltage pulses so as to alternately provide a first pulse width and a second pulse width as the power supply voltage pulses propagate over at least one time period.

[161] In this case, the first motor 151 may be affected by a rapid change in rotation speed based on the pulse width difference between the power supply voltage pulses, and accordingly, the first motor 151 may vibrate.

[162] The vibration of the first motor 151 may be transmitted to the body of the discharge station 100 and the dust collection container 15 connected to the discharge station 100 . That is, the dust collection container 15 can vibrate in accordance with the vibration of the first motor 151, and foreign matter in the dust collection container 15 can be discharged more efficiently in accordance with the vibration. For example, even foreign substances that are not discharged from the dust collection container 15 despite the suction air flow, since they are caught by the internal components of the dust collection container 15, can be discharged from the dust collection container 15 in accordance with the vibration of the dust collection container 15 along with the suction air flow.

[163] The controller 140 according to an embodiment may repeat the on/off control of the first motor 151 when the dust collection container 15 is separated from the discharge station 100 or a stop command is input, or on the condition that the first motor 151 does not complete a predetermined number of on operations ( i.e. a specified duration of operating time).

[164] The controller 140, when the dust collection container 15 is connected to the discharge station 100, and then separated from the discharge station 100, can drive the first motor 151 for a predetermined time that is predetermined for foreign substances remaining in the suction flow path 180 , for collection by collection 190.

[165] The controller 140 according to an embodiment can control the flow path valve 165 in addition to controlling the first motor 151 to periodically open and close the suction flow path 180 while the suction air flow of the suction fan 153 is supplied in accordance with the actuation first engine 151.

[166] That is, the controller 140 controls the second motor 161 so that the flow path valve 163 periodically opens and closes the suction flow path 180 to re-introduce and stop the suction air flow into the dust collection container 15, so that the air flow inside the dust collection container 15 periodically changes . In other words, the flow path valve 163 can regulate the flow rate of air moved by the suction fan 153 and completely stop the suction air flow that may remain during shutdown when voltage is not supplied to the first motor 151, thereby more effectively changing the air flow inside the dust collection container 15.

[167] In this case, the controller 140 can determine whether the suction flow path 180 is open or closed by the flow path valve 163 based on the output value of the position detection sensor 130, and drive the first motor 151 based on the opening or closing of the suction flow path 180, so that the noise and overload of the first motor 151 can be eliminated.

[168] In detail, the controller 140 controls the first motor 151 to turn on when the flow path valve 163 opens the suction flow path 180, and controls the first motor 151 to turn off when the flow path valve 163 closes the suction flow path 180.

[169] That is, the controller 140 controls the first motor 151 and the second motor 161 in conjunction with each other, thereby more efficiently supplying and repeating the suction air flow and preventing the suction fan 153 from causing noise due to rotation when the suction flow path 180 is closed when reducing overload of the first engine 151.

[170] The controller 140 may control the second motor 161 such that the flow path valve 163 opens and closes the suction flow path 180 in a predetermined cycle, or may control the second motor 161 to operate in accordance with the driving time of the first motor 151, which changes whenever the first motor 151 is alternately turned on and off.

[171] That is, when the on time during which voltage is supplied to the first motor 151 or the off time during which voltage is not supplied to the first motor 151 changes, the controller 140 may control the second motor 161 by operating the flow channel valve 163 according to the changed on or off time.

[172] The controller 140 according to an embodiment may control the flow path valve 163 to close the suction flow path 180 when the dust collection container 15 is separated from the discharge station 100 . That is, the controller 140 may control the second motor 161 such that the flow path valve 163 closes the suction flow path 180.

[173] In this case, closing the suction flow path 180 according to the embodiment can be performed after driving the first motor 150 for a predetermined time, which is set so that foreign substances remaining in the suction flow path 180 are collected by a collector 190.

[174] An embodiment in which the suction device 150 (first motor 151) repeats the on and off operations to remove foreign substances from the dust collection container 15 will be described in detail below.

[175] The controller 140 according to an embodiment, in response to receiving an action command for the suction mode through the input device 120, can control the suction device 150 to operate by continuously supplying voltage to the suction device 150 and controlling the flow control device 160 to open the passage. 180 suction flow so that the suction fan 153 rotates continuously without closing the suction flow path 180.

[176] The controller 140 according to an embodiment can determine whether the collector 190 is in a full state based on the output of the collector sensor 195, and when the collector 190 is in a full state, the controller 140 can control the display device 170 to display the filling level of the collector 190 .

[177] The controller 140 in accordance with an embodiment may control the ultraviolet irradiator 185 to irradiate the dust collection container 15 or collection 190 with ultraviolet rays.

[178] In detail, the controller 140 may control the ultraviolet ultraviolet irradiation lamp 185 when the suction device 150 operates to remove foreign substances from the dust collection container 15, and may control the ultraviolet ultraviolet irradiation lamp 185 based on a user input inputted through the input device 120.

[179] The controller 140 according to an embodiment, in response to receiving user input for the display mode through the input device 120, can control the display device 170 to emit light.

[180] The controller 140 may include at least one memory device in which a program for performing the operations described above and the operations described below is stored, and at least one processor for executing the stored program. When memory and processor are provided in the plural, multiple memories and multiple processors may be integrated on a single chip or may be provided at physically separate locations.

[181] The suction device 150 according to an embodiment may supply a suction air flow to the dust collection container 15, and for this purpose may include a suction fan 153 and a first motor 151 for transmitting power to the suction fan 153.

[182] The first motor 151 rotates in accordance with the supply voltage, transmitting a rotational force to the suction fan 153.

[183] The suction fan 153 rotates based on the power supplied from the first motor 151 to move air from the dust collection container 15 to the discharge station 100 .

[184] For this purpose, a suction fan 155 may be provided at the other end of the suction flow path 180, one end of which is connected to the dust collection container 15, and may be mechanically connected to the first motor 151 to receive power from the first motor 151.

[185] The flow control device 160 according to an embodiment can open and close the suction flow path 180 in a predetermined cycle when voltage is applied. To this end, the flow control device 160 includes a flow path valve 163 capable of opening and closing the suction flow path 180, and a second motor 161 that supplies power to the flow path valve 163.

[186] The second motor 161 may provide power to the flow path valve 163 to open and close the suction flow path 180 .

[187] In detail, the second motor 161, under the control of the controller 140, may provide power to the flow channel valve 163 in a predetermined cycle, or may provide power to the flow channel valve 163 to match the driving time of the first motor 151, which changes whenever the first motor 151 alternately turns on and off.

[188] The flow path valve 163 according to an embodiment can open and close the suction flow path 180 based on the power supplied by the second motor 161. For this purpose, the flow path valve 163 may be provided in the suction flow path 180.

[189] For example, the flow path valve 163 may include a plate-shaped body that can reciprocate in one direction, and can open and close the suction flow path 180 by the reciprocating motion of the body.

[190] In addition, the flow channel valve 163 may include a cylindrical shape made rotatable about a central axis, a body having a cylindrical shape, and slotted portions formed by cutting both sides of the body about the central axis, and the flow channel valve 163 may be configured to open and close the suction flow path 180 when the body and slotted portions are rotated about the central axis.

[191] However, the type of flow path valve 163 is not limited to the above example, and the size of the flow path 163 can be implemented without limitation as long as it can open and close the suction flow path 180 based on the power transmitted from the second motor 161.

[192] The display device 170 according to an embodiment can display the operating state of the unloading station 100.

[193] For example, the display device 170 may correspond to an LED panel for emitting light, and may include a front display provided on a front surface of the discharge station 100 for emitting light to the outside of the discharge station 100, and an internal display provided at the installation portion 181 for irradiating light into the dust collection container 15 from the inside of the mounting portion 181.

[194] The display device 170 may correspond to an LED panel located on the mounting portion 181 and emit light to the dust collecting container 15 from the inside of the mounting portion 181.

[195] However, the position and type of the display device 170 is not limited to this, as long as the display device 170 can display the operating state.

[196] The ultraviolet irradiator 185 in accordance with an embodiment can irradiate the dust collection container 15 or collection 190 with ultraviolet rays.

[197] For this purpose, the ultraviolet irradiator 185 may be provided in the form of an ultraviolet lamp provided on the mounting portion 181 and emitting ultraviolet rays. In this case, ultraviolet rays emitted by the ultraviolet irradiator 185 can be emitted into the dust collection container 15 connected to the discharge station 100, and emitted into the collection 190 through the suction flow path 180.

[198] In addition, the ultraviolet irradiator 185 according to an embodiment may include a motor and may irradiate the dust collection container 15 or collection 190 with ultraviolet rays while mechanically adjusting the irradiation angle based on the rotating force of the motor.

[201] The collector sensor 195 in accordance with an embodiment can determine whether the collector 190 is in a full state.

[202] For example, the sump sensor 195 may be configured as a pressure sensor, and when the sump 190 is in a full state and obstructs the suction air flow of the suction device 150, the sump sensor 195 can detect a pressure other than the pressure during normal operation. With this configuration, the controller 140 can determine that the reservoir 190 is in a full state when the reservoir sensor 195 outputs a pressure different from the pressure during normal operation.

[203] However, the collection sensor 195 is not limited to the above example and may be various, as long as it can detect the degree of filling of the collection container 190, for example, by an optical sensor or a camera.

[204] The components of the unloading station 100 have been described in detail above. The following description will be made regarding supplying uneven suction air flow to the dust collection container 15 so that foreign substances in the dust collection container 15 are effectively discharged.

[205] First, an embodiment in which, to supply irregular suction air flow to the dust collection container 15, the suction device 150 is controlled to operate continuously and the flow control device 160 is controlled to periodically open and close the suction flow path 180 will be described in detail.

[210] For example, the user may input an action command by pressing a button corresponding to the input device 120.

[211] Regardless of whether the operation is initiated by connecting the dust collection container 15 or by inputting an action command from the user, the details of the operation of removing foreign matter from the dust collection container 15 are the same, and further the operation of removing foreign matter from the dust collection container 15 will be described with with reference to FIGS. 6 and 7.

[212] The controller 140, when the initiation of the operation is determined based on the connection of the dust collection container 15 or the user input of the action command, can control the suction device 150 to carry out the dust removal operation. That is, the controller 140 may supply voltage to the suction device 150 to drive the suction fan 153 to generate a suction air flow.

[213] In addition, the controller 140 may control the flow control device 160 to periodically open and close the suction flow path 180 during operation of the suction device 150. That is, the controller 140 may apply voltage to the flow control device 160 to open and close the suction flow path 180 in a predetermined cycle.

[214] With this configuration, the suction device 150 can continuously generate suction air flow by the suction fan 153, and the flow control device 160 can periodically open and close the suction flow path 180 to periodically change the flow rate of the suction air flow generated by the suction device 150.

[215] Since the direction of the air flow changes instantaneously, some foreign matter having resistance in a particular direction may lose resistance due to the air flow in another direction, and may be thrown out of the dust collection container 15 along with the air flow.

[216] In this case, foreign substances separated from the dust collection container 15 and discharged can be transported with the air when the suction fan 155 is driven and collected in the collector 190 provided in the suction flow path 180.

[217] That is, the controller 140 can change the air flow inside the dust collection container 15 by causing the suction flow path 180 to be periodically opened or closed by the flow control device 160. With this configuration, foreign substances from the dust collection container 15 can be discharged more efficiently.

[218] The controller 140 according to an embodiment may control the suction device 150 and the flow control device 160 to stop the dust discharge operation when a predetermined operating time T _O has expired after the operation of the suction device 150 is initiated.

[219] That is, the controller 140 can control the suction device 150 and the flow control device 160 to carry out operation during a predetermined operation time T _O to discharge foreign substances from the dust collection container 15, and when the predetermined operation time T _O has expired after the operation is initiated, may stop supplying voltage to the suction device 150 and the flow control device 160.

[220] In this case, the flow control device 160 may repeat the opening and closing of the suction flow path 180 a predetermined number of times (for example, five times) during a predetermined operating time T _O. That is, the predetermined operating time T _O may be a time set for repeating the opening and closing of the suction flow path 180 a predetermined number of times (for example, five times) in consideration of the opening and closing period of the flow control device 160 .

[221] In this case, the controller 140 may set the operating time T _O to be large because the frequency of the external power supply becomes lower. As the external power frequency becomes lower, the revolutions per hour of the second motor 151 driving the flow control device 160 can be increased, and the opening and closing period of the flow control device 160 can be increased. Therefore, the controller 140 can adjust the operating time T _O so that the number of times the suction flow path 180 is opened and closed by the flow control device 160 is constant even when the external power frequency changes.

[222] For example, when the frequency of the external power supply is 60 Hertz (Hz), the opening and closing period of the flow control device 160 may correspond to 3.3 seconds, and when the frequency of the external power supply is 50 Hz, the opening and closing period of the flow control device 160 may correspond to 3.9 seconds. Therefore, the controller 140 can enable the suction device 150 and the flow control device 160 to operate for an operating time (for example, twenty-one seconds) at an external power supply frequency of 50 Hz, which is longer than the operating time (for example, eighteen seconds) at an external power supply frequency 60 Hz.

[223] With this configuration, the discharge station 100 ensures the number of times the suction flow path 180 opens and closes regardless of the external power frequency, thereby ensuring the efficiency of removing foreign substances from the dust collection container 15.

[224] In this case, the controller 140 according to the embodiment may set a predetermined operating time T _O so that the flow control device 160 stops in a state in which the suction flow path 180 is open based on the opening and closing period of the control device 160 flow rate for suction flow channel 180.

[225] The controller 140 may stop supplying voltage to the suction device 150 and the flow control device 160 after the operating time T _O has elapsed. However, even when there is no power supply voltage to the suction device 150, the suction fan 153 may continue to rotate by inertia. Provided that the suction fan 153 is not completely stopped after the voltage supply to the suction device 150 is stopped, the suction air flow in the suction flow path 180 can remain while decreasing. When the suction flow path 180 is closed by the flow control device 160 in a situation where the air pressure changes due to a change in the suction air flow, noise may be generated due to the instantaneous change in air pressure.

[226] The controller 140 may set the operating time T _O such that the flow control device 160 stops in the state of opening the suction flow path 180 when the operating time T _O has expired after the operation is initiated, so that closing of the suction passage 180 is prevented in a situation in which the suction fan 153 continues to rotate after the power supply to the suction device 150 is stopped, so that noise is prevented.

[227] For example, when the flow control device 160 initiates operation in a closed state of the suction flow path 180, the controller 140 may determine the operating time T _O as an odd multiple of the opening and closing period of the flow control device 160 for the suction flow path 180 taking into account the opening and closing period .

[228] The controller 140 according to an embodiment may control the flow control device 160 to close the suction flow path 180 when a predetermined waiting time T _W (eg, 2.5 seconds) has elapsed after the operating time T _O .

[229] That is, the controller 140 may be able to close the suction flow path 180 by controlling the flow control device 160 after the operation time T _O has elapsed, so that the suction device 150 is protected from foreign substances remaining in the suction flow path 180, and when initiating operation, ensure the ability to turn on the suction device 150 in the state of the open suction flow path 180, so that the noise is reduced.

[230] As described above, the controller 140 controls the flow control device 160 to open the suction flow path 180 for a waiting time T _W after the operating time T _O and then close the suction flow path 180 .

[231] That is, the controller 140 can prevent the suction flow path 180 from closing before the suction fan 153 is completely stopped after the voltage supply to the suction device 150 is stopped, and can control the flow control device 160 to close the suction flow path 180 when the suction fan 153 is completely stopped when the waiting time T _W has expired after the running time T _O.

[232] In other words, the controller 140, in order to prevent noise from occurring due to a change in the suction air flow by the residual rotating force after the operation of removing foreign matter from the dust collection container 15 is stopped, can stop the flow control device 160 so that the suction flow path 180 remains open. within the specified waiting time. In addition, the controller 140 can control the flow control device 160 to close the suction flow path 180 after a waiting time, so that the suction device 150 is protected from foreign substances remaining in the suction flow path 180, and when initiating the foreign substance removal operation, can cause the suction device to operate 150 in a situation where the suction flow path 180 is open, so that noise is prevented from occurring.

[233] In this case, the controller 140 can adjust the timing of determining the suction flow path 180 in accordance with the frequency of the external power supply.

[234] As described above, as the frequency of the external power supply becomes lower, the rotation speed of the second motor 161 decreases, and the opening and closing period of the flow control device 160 for the suction flow path 180 can be increased.

[235] Accordingly, as the frequency of the external power supply becomes lower, the closing time of the suction flow path 180 may increase. For example, the closing time at 60 Hz may be 0.8 seconds, and the closing time at 50 Hz may be 1.05 seconds.

[236] Accordingly, when controlling the flow control device 160 to close the suction flow path 180 after the waiting time T _W has elapsed, the controller 140 may delay the time at which the suction flow path 180 is determined to be closed in proportion to the decrease in the external power frequency.

[237] For example, referring to FIG. 8, the controller 140, when the external power frequency is 60 Hz, may determine the suction flow path 180 to be closed when the time T _a1 (for example, 0.1 second) has elapsed because the position detection sensor 130 outputs a first value indicating the closing of the suction flow path 180 after the waiting time T _W. In addition, the controller 140, as shown in FIG. 8, when the external power frequency is 50 Hz, can determine the suction flow path 180 to be closed when the time T _a2 (for example, 0.5 seconds) has elapsed because the position detection sensor 130 outputs a first value indicating closing of the suction flow path 180 after the waiting time T _W .

[238] That is, the controller 140 may delay the time at which the suction flow path 180 is determined to be closed after the first value of the position detection sensor 130 is triggered, since the closing time of the suction flow path 180 increases when the external power frequency becomes lower.

[239] With this configuration, when the operation of removing foreign substances from the dust collection container 15 is newly initiated, the suction device 150 can initiate the operation in a situation in which the suction flow path 180 is open, regardless of the external power frequency.

[240] That is, the controller 140 may be configured, in response to a decrease in the frequency of the external power supply, to delay the timing at which the suction flow path 180 is determined to be closed after the first value begins to be output by the position detection sensor 130, so that the time , required for triggering the opening of the suction flow path 180 by the flow control device 160 when a new operation is initiated, can be constant regardless of the frequency of the external power supply, and thus the variation in noise caused by different frequencies of the external power supply can be reduced. As shown in FIG. 8, the time T _b1 required to open the suction flow path 180 at an external supply frequency of 60 Hz may be the same or may differ slightly from the time T _b2 required to open the suction flow path 180 at an external supply frequency of 50 Hz. Hz

[241] In other words, given that the closing time of the suction flow path 180 at a frequency of 50 Hz external power is greater than that at a frequency of 60 Hz external power, the controller 140 may delay the timing of closing determination at a frequency of 50 Hz external power, which should be more later than at a frequency of 60 Hz external power supply, so that the flow control device 160 additionally operates during the delay time. With this configuration, the time remaining to close at 60 Hz external power can be the same or slightly different from the time at 50 Hz external power, so that when a new operation is initiated, the change in noise generation is negligible.

[242] When applying voltage to the suction device 150 to initiate operation, the controller 140 may gradually increase the amount of voltage supplied during the soft start time, and from the time when the soft start time has elapsed, supply a voltage having a value corresponding to the target (preset) value. ) voltage.

[243] That is, the voltage supplied to the suction device 150 can gradually increase during the soft start time and reach the target voltage, and then can be maintained at the target voltage until the operation time T _O is reached.

[244] This is done to prevent strong vibration of the first motor 151 because it is momentarily supplied with a high voltage, and to prevent vibration of the unloading station 100 due to strong vibration of the first motor 151 while preventing noise due to vibration of the unloading station 100 from occurring.

[245] During soft starting, during which the voltage supplied to the suction device 150 increases, the flow rate of the suction air flow generated by the suction device 150 may increase, and when the suction flow path 180 is closed in a situation in which the flow rate of the suction air flow increases, noise may be generated due to a sudden change in air pressure in the suction flow path 180.

[246] The controller 140 may control the flow control device 160 to open the suction flow path 180 during a soft start, during which the voltage supplied to the suction device 150 is increased to a target voltage to prevent noise from occurring.

[247] For example, the controller 140, as shown in FIGS. 6 and 7, can determine a soft start time T _SS corresponding to the opening time T _f1 of the flow path 180 taking into account the opening and closing period T _{f of} the flow control device 160 for the suction flow path 180 .

[248] That is, the soft start time T _SS can be defined as the time from the time when the opening of the suction flow path 180 begins to the time when the closing of the suction flow path 180 begins, while the flow control device 160 is continuously operated.

[249] In addition, the controller 140 can determine the soft start time T _SS regardless of the opening and closing period T _f of the flow path device 160 of the flow control device 160 . For example, the controller 140 may set the soft start time T _SS to be greater than the opening time T _f1 of the suction flow path 180 during the opening and closing period T _f of the flow control device 160 for the suction flow path 180, so that vibration of the unloading station 100 can be minimized. .

[250] In this case, the controller 140, as shown in FIG. 9, can stop the flow control device 160 for a time T _f3 corresponding to the difference between the soft start time T _SS and the opening time T _f1 of the suction flow channel 180, so that the channel 180 suction flow is open during T _SS soft start.

[251] In addition, the controller 140 according to the embodiment, when starting the operation of removing foreign substances from the dust collection container 15 in the state in which the suction flow path 180 is open, can stop the operation of the flow control device 160 for a predetermined time, so that the path 180 suction flow is open during the soft start time T _SS , and can control the flow control device 160 to close the suction flow path 180 after the soft start time T _SS .

[252] With this configuration, the unloading station 100 can prevent noise from occurring due to the closing of the suction flow path 180 during a soft start during which the voltage supplied to the suction device 150 is increased.

[253] The above description has been made with respect to an embodiment in which, in order to supply uneven suction air flow to the dust collection container 15, the suction device 150 is controlled to carry out continuous operation, and the flow control device 160 is controlled to periodically open and close the suction flow path 180. Next, an embodiment in which a stop command is received from the user during continuous operation of the suction device 150, and the flow control device 160 periodically opens and closes the suction flow path 180 will be described in detail.

[254] FIG. 10 is a view showing a case in which the discharge station 100 stops operation in accordance with the input of a stop command, with the suction flow path being opened according to the embodiment of the disclosure.

[255] FIG. 11 is a view showing a case in which the unloading station 100 stops operation in accordance with the input of a stop command, and the suction flow path is closed in accordance with the disclosure embodiment.

[256] Referring to FIGS. 10 and 11, the controller 140 according to an embodiment, in response to receiving an input command to stop the dust discharge operation through the input device 120 while the suction device 150 and 160 is operating to discharge dust, may control 160 to open the suction flow path 180 and control the suction device 150 to stop operation after the first waiting time T _W1 (for example, one second) since the stop command is input.

[257] As described above, even when the voltage supply to the suction device 150 is stopped, the suction fan 153 may continue to rotate by inertia. Until the suction fan 153 is completely stopped after the voltage supply to the suction device 150 is stopped, the suction air flow in the suction flow path 180 may remain decreasing. In a situation where the air pressure changes due to a change in the suction air flow, when the suction flow path 180 is closed by the flow control device 160, noise may occur due to the instantaneous change in air pressure.

[258] Therefore, the controller 140, in response to receiving a command to stop the dust discharge operation after the dust discharge operation is initiated, can control the flow control device 160 to stop operation in a state in which the suction flow path 180 is opened by the flow control device 160, so that the suction flow path 180 is prevented from closing in a situation in which the suction fan 153 continues to rotate after the voltage supply to the suction device 150 is stopped, so that noise is prevented from occurring.

[259] In detail, the controller 140 according to the embodiment as shown in FIG. 10, when receiving input of a command to stop the dust discharge operation in a state in which the suction flow path 180 is open, can stop the operation of the flow control device 160 so that so that the suction flow path 180 remains open.

[260] That is, the controller 140, in response to receiving a stop command input when the flow control device 160 is in the opening position of the suction flow path 180 during operation, may stop supplying voltage to the flow control device 160 to maintain the suction flow path 180 open.

[261] The controller 140 may stop supplying voltage to the suction device 150 such that the suction device 150 stops operating when the first waiting time T _W1 has elapsed after the time point at which the stop command is input.

[262] In this case, the controller 140, in accordance with the embodiment, can control the flow control device 160 to close the suction flow path 180 when the second waiting time T _W2 (for example, 2.5 seconds) has elapsed after the time at which the command is input to the stop.

[263] With this configuration, the controller 140 can prevent the suction flow path 180 from closing in a situation in which the suction fan 153 continues to rotate after the power supply to the suction device 150 is stopped, so that noise is prevented from occurring.

[264] Referring to FIG. 11, the controller 140 according to an embodiment, in response to receiving a command input to stop the dust discharge operation in a state in which the suction flow path 180 is closed, may operate the flow control device 160 to open the suction flow path 180 .

[265] That is, the controller 150, in response to receiving a command input to stop dust discharge when the flow control device 160 is in the closing position of the suction flow path 180 during operation, can maintain voltage supply to the flow control device 160 for the first time T _W1 waits after entering the stop command, so that the suction flow path 180 is open. In this case, the first waiting time T _W1 may correspond to the time required to move the flow control device 160 from a position in which the suction flow path 180 is closed to a position in which the suction flow path 180 is open.

[266] The controller 140 may stop supplying voltage to the suction device 150, so that the suction device 150 stops operating when the first waiting time T _W1 has elapsed after the command input time for stopping the dust discharge operation, and the voltage supply to the suction device 150 is stopped, also stop supplying voltage to the flow control device 160, so that the suction device 150 and the flow control device 160 can be stopped in a state in which the suction flow path 180 is opened by the flow control device 160.

[267] As described above, the controller 140 can control the suction device 150 and the flow control device 160 to stop operation when the first waiting time T _W1 counts, and in accordance with an embodiment, can control the suction device 150 and the flow control device 160 to stop operation when determining whether the flow control device 160 opens the suction flow path 180 based on the output value of the position detection sensor 130.

[268] That is, the controller 140 may control the suction device 150 and the flow control device 160 to stop operation in response to determining that the suction flow path 180 is open based on the output value of the position detection sensor 130 after inputting a command to stop the station dust discharge operation 100 unloads.

[269] In this case, the controller 140, in accordance with an embodiment, can control the flow control device 160 to close the suction flow path 180 when the second waiting time T _W2 (for example, 2.5 seconds) has elapsed after the voltage supply to the suction device is stopped. 150.

[270] With this configuration, the controller 140 can prevent the suction flow path 180 from closing in a situation where the suction fan 153 continues to rotate after the power supply to the suction device 150 is stopped, thereby preventing noise from occurring.

[271] As described above, the controller 140 completes the cycle by finally closing the suction flow path 180 upon inputting a command to stop the dust discharge operation, so that the suction device 150 can be protected from foreign substances remaining in the suction flow path 180 and when re-initiated the foreign matter removal operation enables the suction device 150 to operate in the state of the open suction flow path 180, so that noise can be prevented from occurring.

[272] In the above, an embodiment has been described in which the suction air flow supplied to the dust collection container 15 is changed by the flow control device 160 in a situation in which the suction device 150 is operated continuously. Next, an embodiment in which the suction air flow supplied to the dust collection container 15 is changed by changing the on-off control of the first motor 151 of the suction device 150 will be described in detail.

[273] FIG. 12 is a graph showing time-varying on/off control of the first motor 151 according to an embodiment of the disclosure, and FIG. 13 is a view for describing a case in which a different rotation speed is provided whenever the an operation of turning on the first motor 151 in accordance with an embodiment of the disclosure.

[274] Referring to FIG. 12, the discharge station 100 according to an embodiment can control the suction device 150 so that foreign matter in the dust collection container 15 is discharged when the dust collection container 15 of the vacuum cleaner 10 is connected to the discharge station 100.

[275] In detail, the discharge station 100 can determine whether the dust collection container 15 is connected to the discharge station 100 based on the output value of the sensor 110, and when the dust collection container 15 is connected to the discharge station 100, initiate control of the first motor 151.

[276] However, controller 140 may additionally take into account a user control command input through input device 120 in addition to the output value of sensor 110 such that control of the first motor 151 is initiated only when an action command is provided from the user.

[277] In this case, when the first motor 151 remains turned on and the same suction air flow is supplied to the dust collection container 15, some foreign substances may be caught in the internal components of the dust collection container 15 and may not be discharged to the outside. For example, foreign matter such as hair may be caught in the internal structure of the dust collection container 15 and, despite the suction air flow, may remain inside the dust collection container 15 without being separated to the outside of the dust collection container 15. That is, the suction air flow supplied to the inside of the dust collection container 15 may form only in one and the same direction. Accordingly, some foreign matter may have resistance in the direction in which the suction air flow is formed, and thus may not be separated to the outside of the dust collection container 15 by the suction air flow. Accordingly, foreign substances inside the dust collection container 15 cannot be discharged effectively.

[278] The discharge station 100 according to the embodiment, while the suction air flow is supplied to the dust collection container 15 by the suction fan 153 and the air in the dust collection container 15 is sucked, changes the suction air flow so that the air flow rate inside the dust collection container 15 changes, and the air flow inside the dust collection container 15 changes.

[279] The controller 140 for supplying uneven suction air flow to the dust collection container 15 may adjust at least one of the driving time or the rotation speed of the first motor 151 when the first motor 151 is repeatedly turned on/off.

[280] That is, as shown in FIG. 12, the controller 140 may control the first motor 151 such that the first motor 151 is turned on and off repeatedly.

[281] In detail, the controller 140 may control the first motor 151 such that the first motor 151 is turned on and then turned off at each of a plurality of time periods.

[282] For example, referring to FIG. 12, the first motor 151 may repeat turning on/off according to the passage of time periods. In this case, one time period may include an on time during which the first motor 151 is turned on while the rated voltage is applied, and an off time during which the first motor 151 is turned off without the rated voltage being applied, and for changing the rotation speed at the beginning of each time period. segment, the time (soft start time) elapsed until the voltage supplied to the first motor 151 rises to the rated voltage may be set differently for each time segment.

[283] In this case, the controller 140 adjusts at least one of the time during which the first motor 151 is turned on or the time during which the first motor 151 is turned off whenever the first engine 151 is alternately turned on and off, that is, each times when the timing is changed so that the driving time of the first motor 151 is adjusted.

[284] For example, the turn-on time in the first time period may be longer than the turn-on time in the second time period, and the turn-off time in the first time period may be shorter than the turn-off time in the third time period.

[285] In addition, the controller 140 may adjust the duration of a power supply voltage pulse supplied to the first motor 151 whenever the first motor 151 is alternately turned on and off to adjust the rotation speed of the first motor 151.

[286] For example, referring to FIG. 13, the controller 140 may set the duration of the power supply voltage pulse supplied to the first motor 151 during the on time of the first time period to 80%, and may set the duration of the power supply voltage pulse supplied to the first motor 151, during the turn-on time of the second time period followed by the first time period up to 65%. Accordingly, the rotation speed of the first motor 151 may be reduced as it progresses from the first time period to the second time period.

[287] In this case, the suction fan 153 can supply the dust collection container 15 with a suction air flow of different suction power whenever the first motor 151 is alternately turned on and off according to a change in the driving time of the first motor 151 or the rotation speed of the first motor 151 , and since the internal pressure of the dust collection container 15 changes due to the uneven suction air flow, foreign substances in the dust collection container 15 can be smoothly discharged from the dust collection container 15.

[288] That is, when the air flow rate inside the dust collection container 15 changes, the air spreads in all directions in the interior of the dust collection container 15, and thus the air flow inside the dust collection container 15 can change in various directions.

[289] Since the direction of the air flow changes instantaneously, some foreign matter having resistance in a particular direction may lose resistance due to the air flow in another direction, and may be thrown out of the dust collection container 15 along with the air flow.

[290] In this case, foreign substances separated from the dust collection container 15 and discharged can be transported with the air when the suction fan 153 is driven and collected in the collection 190 provided in the suction flow path 180.

[291] That is, the controller 140 repeats the supply and interruption of the supply of suction air flow into the dust collection container 15 through the on-off control of the first motor 151, and changes the supply time or suction power when supplying the suction air flow, thereby periodically changing the air flow inside the dust collection container container 15. With this configuration, foreign substances from the dust collection container 15 can be discharged more efficiently.

[292] The above description has been made by supplying irregular suction air flow to the dust collection container 15 by repeatedly turning on and off the first motor 151 of the suction device 150 so that foreign substances from the dust collection container 15 are effectively discharged. Next, transmission of vibration to the dust collection container 15 so that foreign substances in the dust collection container 15 are effectively discharged will be described in detail.

[293] FIG. 14 is a view for describing a case in which the first motor 151 vibrates to transmit vibration to the dust collecting container 15 according to an embodiment of the disclosure.

[294] Referring to FIG. 14, controller 140 in accordance with an embodiment may specify different pulse widths for power supply voltage pulses within at least one of the time periods in which the first motor 150 is turned on and off, such that the first motor 151 vibrates.

[295] That is, the controller 140 sets the power supply voltage pulse widths to be different from each other within the turn-on time during which the first motor 151 is turned on when the voltage is applied, and provides the first motor 150 with the predetermined pulse widths.

[296] For example, referring to FIG. 14, the controller 140 may adjust the durations of the power supply voltage pulses so that the first pulse duration ① and the second pulse duration ② are provided alternately as the power supply voltage pulses pass in the third time period.

[297] In this case, the first motor 151 may be subject to a rapid change in rotation speed based on the pulse width difference between the power supply voltage pulses, so that the first motor 151 may vibrate.

[298] The vibration of the first motor 151 may be transmitted to the body of the discharge station 100 and the dust collection container 15 connected to the discharge station 100 . That is, the dust collection container 15 can vibrate in accordance with the vibration of the first motor 151, and foreign substances in the dust collection container 15 can be more efficiently discharged in accordance with the vibration. For example, even foreign substances that are not ejected from the dust collection container 15 despite the suction air flow, due to being captured by the internal components of the dust collection container 15, can be discharged from the dust collection container 15 in accordance with the vibration of the dust collection container 15 along with the suction air flow.

[299] As described above, the discharge station 100 according to the embodiment repeats the supply and interruption of the supply of suction air flow to the dust collection container 15 through the on-off control of the first motor 151, and adjusts the pulse durations during supply of the suction air flow within one and the same time period to cause vibration of the dust collection container 15, so that foreign substances in the dust collection container 15 can be discharged more efficiently.

[300] The controller 140 according to an embodiment may repeat the on/off control of the first motor 151 until the dust collection container 15 is separated from the discharge station 100 or the first motor 151 is turned on a predetermined number of times.

[301] The controller 140 according to an embodiment may drive the first motor 151 for a predetermined time, which is set to collect foreign substances remaining in the suction flow path 180 by the collection 190 when the dust collection container 15 is connected to the discharge station 100, and then separated from the unloading station 100.

[302] In the above, vibration transmission to the dust collection container 15 has been described in detail, so that foreign substances in the dust collection container 15 are effectively discharged. The following description will be made regarding the control of the second motor 161 to open and close the suction flow path 180 by the flow control device 160 in combination with the control of the first motor 151 to create an uneven suction air flow.

[303] FIG. 15 is a view for describing control of the first motor 151 in accordance with the operation of the flow channel valve 163 according to an embodiment of the disclosure.

[304] Referring to FIG. 15, the controller 140 according to an embodiment can control the flow control device 160 in addition to controlling the first motor 151 to periodically open and close the suction flow path 180 while the suction air flow is supplied by the suction fan 153 in accordance with the driving of the suction devices 150.

[305] That is, the controller 140 controls the second motor 161 such that the flow path valve 163 periodically opens and closes the suction flow path 180 to re-supply and stop supplying suction air flow to the dust collection container 15, so that air flow inside the dust collection container 15 periodically changes. In other words, the flow channel valve 163 can regulate the flow of air moved by the suction fan 153 and completely stop the suction air flow, which may remain during the shutdown time during which voltage is not applied to the first motor 151, thereby more effectively changing the air flow inside the dust container 15.

[306] In this case, the controller 140 determines whether the suction flow path 180 is open or closed by the flow path valve 163 based on the output value of the position detection sensor 130, and based on whether the suction flow path 180 is open or closed, drives the first motor 151, so that noise and overload of the first motor 151 can be reduced.

[307] In detail, the controller 140 controls the first motor 151 to turn on when the flow control device 160 opens the suction flow path 180, and controls the first motor 151 to turn off when the flow control device 160 closes the suction flow path 180.

[308] That is, the controller 140 controls the first motor 151 and the second motor 161 in communication with each other, thereby more efficiently supplying and re-supplying the suction air flow and preventing the suction fan 153 from causing noise due to rotation when the suction flow path 180 is closed. and reducing overload of the first engine 151.

[309] In this case, the controller 140 may control the second motor 161 so that the flow path valve 163 opens and closes the suction flow path 180 in a predetermined cycle, and may control the second motor 161 to match the driving time of the first motor 151, which changes whenever the first motor 151 is alternately turned on and off.

[310] That is, when the on time during which voltage is supplied to the first motor 151 or the off time during which voltage is not supplied to the first motor 151 changes, the controller 140 may control the second motor 161 by operating the flow channel valve 163 to accommodate changed on and off times.

[311] The controller 140 according to an embodiment may control the flow path valve 163 to close the suction flow path 180 when the dust collection container 15 is separated from the discharge station 100 . That is, the controller 140 may control the second motor 161 such that the flow path valve 163 closes the suction flow path 180.

[312] In this case, closing the suction flow path 180 can be performed after driving the first motor 151 for a predetermined time, which is predetermined so that foreign substances remaining in the suction flow path 180 are collected by the collector 190.

[313] Next, a suction mode in which the suction device 150 continuously operates with the open suction flow path 180 will be described in detail.

[314] FIG. 16 is a view for describing a case in which the discharge station 100 performs a suction mode according to the disclosure embodiment.

[315] Referring to FIG. 16, the controller 140 according to the embodiment, upon receiving an action command for the suction mode through the input device 120, can control the suction device 150 and the flow control device 160 so that the suction air flow is continuously supplied to a state in which the suction flow path 180 is open.

[316] In detail, the controller 140, in response to receiving an action command for the suction mode from the user in a state in which the dust collection container 15 is connected to the discharge station 100, can control the suction device 150 and the flow control device 160 to execute the suction mode.

[317] The controller 140 can determine whether the dust collection container 15 is connected to the discharge station 100 based on the output of the sensor 110, and determine the input of the suction mode based on the output of the input device 120.

[318] The suction mode is a mode for checking the suction force of the suction device 150 and may refer to a cycle in which suction air flow is continuously supplied in a state in which the suction flow path 180 is open.

[319] The controller 140, in response to receiving the suction mode input, may control the flow control device 160 to open the suction flow path 180.

[320] In detail, referring to FIG. 16, the controller 140 may supply the flow control device 160 with a voltage to open the suction flow path 180 when the suction flow path 180 is closed while receiving a suction mode input, and may stop supplying the voltage to the device 160 adjusting the flow rate when the suction flow path 180 becomes open.

[321] In addition, different from FIG. 16, the controller 140, when the suction flow path 180 is open at the time of receiving the suction mode input, can control the flow control device 160 to turn off so that the suction flow path 180 remains open.

[322] The controller 140, in response to receiving the suction mode input, may control the suction device 150 to operate and may continuously supply voltage to the first motor 151.

[323] Referring to FIG. 16, the controller 140 may execute the suction mode until the dust collection container 15 is separated from the discharge station 100 or a stop command input is received. That is, the controller 140 may control the suction device 150 to turn off when the dust collection container 15 is separated from the discharge station 100 or a command to stop the suction mode is received. However, the controller 140 according to the embodiment can control the suction device 150 to perform a suction mode only during a predetermined operation time and stop after the predetermined operation time.

[324] In addition, the controller 140 in accordance with the embodiment may control the flow control device 160 to close the suction flow path 180 when a predetermined waiting time has elapsed after completion of the suction mode.

[325] That is, the controller 140 may be able to close the suction flow path 180 by controlling the flow control device 160 when a predetermined waiting time has elapsed after the power supply to the suction device 150 is stopped, so that the suction flow path 180 is prevented from closing in a situation in which the suction the fan 153 continues to rotate after the power supply to the suction device 150 is stopped, and thus noise is prevented from occurring.

[326] The controller 140 in accordance with the embodiment completes the cycle by finally closing the suction flow path 180 after completing the suction mode, so that the suction device 150 can be protected from foreign substances remaining in the suction flow path 180 and when the foreign matter removal operation is re-initiated substances allows the suction device 150 to operate in the state of the open suction flow path 180, so that noise can be prevented from occurring.

[327] Below, a display mode in which the display device 170 continuously emits light will be described in detail.

[328] FIG. 17 is a view for describing a case in which the unloading station 100 executes a display mode according to an embodiment of the disclosure.

[329] Referring to FIG. 17, the controller 140 according to the embodiment, in accordance with receiving display mode input through the input device 120, can execute the display mode by controlling the display device 170 to emit light.

[330] In detail, the controller 140 in accordance with receiving input of the display mode through the input device 120 can control at least one of the front display 170a provided on the front surface of the unloading station 100 to emit light to the outside of the unloading station 100 or the inner display 170b provided at the mounting portion 181 to emit light from inside the mounting portion 181 into the dust collection container 15.

[331] The controller 140, when executing the display mode, can control the display device 170 to continuously emit light regardless of the operation of the suction device 150, and can continue to execute the display mode until the external power supply is turned off.

[332] Next, an embodiment in which the display device 170 displays whether the collector 190 performs collection according to whether the collector 190 is in a full state will be described in detail.

[333] FIG. 18 is a view for describing a case in which the unloading station 100 determines the filling degree of the collector 190 in accordance with an embodiment of the disclosure.

[334] Referring to FIG. 18, the controller 140 in accordance with an embodiment can determine whether the collector 190 is in a full state based on the output of the collector sensor 195, and can control the display device 170 to display the filling degree of the collector 190 when the collector 190 is in a full state.

[335] For example, the controller 140 may control the front display 170a to output a "red" light when the collector 190 is in a full state, and control the front display 170a to continue outputting a "red" light until the dust bag 193 of the collector 190 will not be replaced.

[336] The collector sensor 195 in accordance with an embodiment may be configured as a pressure sensor located in the suction flow path 180 . For example, the collector sensor 195 may be provided in the collector body 191, as shown in FIG. 18. However, the disclosure is not limited to this, and the collector sensor 195 may be positioned in various ways as long as it can sense the pressure of the suction air flow. For example, the collection sensor 195 may be located on the suction device body 106.

[337] In this case, the collector sensor 195 can measure a pressure different from the pressure during normal operation when the collector 190, in a full state, obstructs the suction air flow of the suction device 150.

[338] With this configuration, the controller 140 can determine the filling degree of the collector 190 when the collector sensor 195 outputs a pressure different from the pressure during normal operation, and can control the display device 170 to display the filling degree of the collector 190.

[339] However, the collector sensor 195 is not limited to the above example and may be configured as an optical sensor or camera provided in the collector body 191 and capable of detecting the degree of filling of the collector 190.

[340] As described above, the discharge station 100 may notify the user of a situation in which foreign matter in the dust collection container 15 is not normally discharged due to the filling level of the collection container 190, and may notify the user to replace the dust bag 193.

[342] FIG. 19 is a view for describing a case in which the unloading station 100 emits ultraviolet rays according to an embodiment of the disclosure.

[343] Referring to FIG. 19, the controller 140 in accordance with an embodiment may control the ultraviolet irradiator 185 to irradiate the dust collection container 15 or collection 190 with ultraviolet rays for sterilization.

[344] The ultraviolet irradiator 185 in accordance with an embodiment may irradiate the dust collection container 15 or collection 190 with ultraviolet rays.

[345] For this purpose, the ultraviolet irradiator 185 may be configured as an ultraviolet lamp that is provided on the mounting portion 181 and emits ultraviolet rays. In this case, ultraviolet rays from the ultraviolet irradiator 185 can be transmitted to the dust collection container 15 connected to the discharge station 100, and can be transmitted to the collection 190 through the suction flow path 180.

[346] In addition, the ultraviolet irradiator 185 according to an embodiment may include a motor and may irradiate the dust collection container 15 or collection 190 with ultraviolet rays while mechanically adjusting the irradiation angle based on the rotating force of the motor.

[347] In addition, the ultraviolet irradiator 185 in accordance with the embodiment may include a plurality of ultraviolet lamps and may irradiate the dust collection container 15 or collection 190 with ultraviolet rays while electronically adjusting the irradiation angle by adjusting the irradiation intensity of each of the plurality of ultraviolet lamps in the array.

[348] In addition, the ultraviolet irradiator 185 according to the embodiment may include an ultraviolet lamp provided on the mounting portion 181 for transferring ultraviolet rays to the dust collection container 15, and an ultraviolet lamp provided on the collection body 191 for transferring ultraviolet rays to collection 190.

[349] The controller 140 may control the ultraviolet irradiator 185 to provide ultraviolet irradiation when the suction device 150 operates to remove foreign matter from the dust collection container 15 according to an embodiment.

[350] In addition, the controller 140 in accordance with the embodiment, when receiving user input for ultraviolet irradiation through the input device 120, can control the ultraviolet irradiator 185 to irradiate ultraviolet rays for a predetermined time.

[351] As such, the discharge station 100 can sterilize the dust collection container 15 and collection 190 by irradiating the dust collection container 15 and collection 190 with ultraviolet rays.

[352] Next, an embodiment of a method for controlling the cleaning device 1 according to the aspect will be described. The cleaning device 1 according to the above-described embodiment can be used for the method of controlling the cleaning device 1. Therefore, the above description made with reference to FIGS. 1 to 19 can be applied to the control method of the cleaning device 1.

[353] FIG. 20 is a flowchart of a control method of the cleaning device 1 according to an embodiment, which shows automatic operation when connected to the dust collection container 15 according to the embodiment of the disclosure.

[354] Referring to FIG. 20, the discharge station 100 of the cleaning device 1 according to the embodiment, when connected to the dust collection container (YES in operation 2010), can control the suction device 150 and the flow control device 160 to carry out dust discharge work in operation 2020 .

[355] That is, the controller 140, in response to determining that the dust collection container 15 is docked with the mounting portion 181 of the discharge station 100 based on the output of the sensor 110, can control the suction device 150 and the flow control device 160 to supply voltage to initiate the foreign matter removal operation. substances from the dust container 15.

[356] The controller 140, when the initiation of operation is determined based on the connection of the dust collection container 15, can control the suction device 150 to carry out the operation. That is, the controller 140 may supply voltage to the suction device 150 to drive the suction fan 153 to generate a suction air flow.

[357] In addition, the controller 140 may control the flow control device 160 to periodically open and close the suction flow path 180 during operation of the suction device 150. That is, the controller 140 may apply voltage to the flow control device 160 to open and close the suction flow path 180 in a predetermined cycle.

[358] With this configuration, the suction device 150 can continuously generate suction air flow through the suction fan 153, and the flow control device 160 can periodically open and close the suction flow path 180, thereby periodically changing the flow rate of the suction air flow generated by the suction device 150.

[359] Since the direction of the air flow changes instantaneously, some foreign substances having resistance in a particular direction may lose resistance due to the air flow in another direction, and may be thrown out of the dust collection container 15 along with the air flow.

[360] The discharge station 100 of the cleaning device 1 according to an embodiment can control the suction device 150 and the flow control device 160 to stop the dust discharge operation when a predetermined operating time T _O (YES in operation 2030) has elapsed after the operation of the suction device 150 is initiated. during operation 2040.

[361] That is, the controller 140 can control the suction device 150 and the flow control device 160 to operate for a predetermined time T _O to discharge foreign substances from the dust collection container 15, and when the predetermined time T _O has expired after the operation is initiated, can stop supplying voltage to the suction device 150 and the flow control device 160.

[362] In this case, the flow control device 160 may repeat the opening and closing of the suction passage 180 a predetermined number of times (for example, five times) during a predetermined operating time T _O. That is, the predetermined operating time T _O may be a time set for repeating the opening and closing of the suction flow path 180 a predetermined number of times (for example, five times) in consideration of the opening and closing period of the flow control device 160 .

[363] In this case, the controller 140 according to the embodiment may set a predetermined operating time T _O such that the flow control device 160 stops operating in the state in which the suction flow path 180 is open based on the opening and closing period of the device 160 flow adjustment for suction flow channel 180.

[364] The controller 140 may set the operating time T _O so that the flow control device 160 stops operating in the opening state of the suction passage 180 when the operating time T _O has expired after the operation is initiated, so that the suction passage 180 is prevented from closing in the state in which the suction fan 153 continues to rotate after the power supply to the suction device 150 is interrupted, so that noise is prevented.

[365] The discharge station 100 of the cleaning device 1 according to an embodiment may control the flow control device 160 to close the suction flow path 180 when a predetermined waiting time T _W (for example, 2.5 seconds) has elapsed (YES in operation 2050) after operating time T _O during operation 2060.

[366] That is, the controller 140 can cause the operation of the flow control device 160 to be stopped so that the suction flow path 180 is opened for a predetermined waiting time to prevent noise from occurring due to a change in the suction air flow caused by the suction force that remains after the removal operation is stopped. foreign substances from the dust collection container 15. In addition, the controller 140 may control the flow control device 160 to close the suction flow path 180 after a waiting time, so that the suction device 150 is protected from foreign substances remaining in the suction flow path 180 and when the operation is initiated removing foreign matter, causing the suction device 150 to operate in an open state of the suction flow path 180 so that the noise is reduced.

[367] FIG. 21 is a flowchart showing a control method of the cleaning device 1, which shows operation in response to input of an action command according to an embodiment of the disclosure.

[368] Referring to FIG. 21, the discharge station 100 of the cleaning device 1 according to the embodiment, when connected to the dust collection container 15 (YES in operation 2110), may be configured in response to receiving an action command (YES in operation 2120), control the suction device 150 and the flow control device 160 to carry out dust discharge work in operation 2130.

[369] Thereafter, the discharge station 100 of the cleaning device 1 according to an embodiment can control the suction device 150 and the flow control device 160 to stop the dust discharge operation when a predetermined operating time T _O has expired (YES at operation 2140) after the suction operation is initiated. devices 150 at operation 2150.

[370] In addition, the controller 140 in accordance with the embodiment may control the flow control device 160 to close the suction flow path 180 when a predetermined waiting time T _W (for example, 2.5 seconds) has elapsed (YES at operation 2160) after the time T _O work during operation 2170.

[371] Since operations 2130-2170 correspond to operations 2030-2060 in FIG. 20, detailed descriptions will be omitted.

[372] FIG. 22 is a flowchart showing a control method of the cleaning device 1, which shows a stopping operation in response to input of a stopping command according to an embodiment of the disclosure.

[373] Referring to FIG. 22, the discharge station 100 of the cleaning device 1 according to an embodiment can control the suction device 150 and the flow control device 160 to carry out dust discharge operation based on the connection of the dust collection container 15 or input of a user operation command. 2210.

[374] In this case, the controller 140 according to the embodiment, when the command to stop the dust discharge operation is input (YES at operation 2220) and the suction flow path 180 is closed (YES at operation 2230), can control the suction device 150 and the adjustment device 160 flow rate to stop the dust discharge operation when the suction flow path 180 becomes open (YES in operation 2240) because the first waiting time T _W1 has expired after the stop command is entered in operation 2250.

[375] That is, the controller 140 according to the embodiment, in response to receiving a command input to stop the dust discharge operation in a state in which the suction flow path 180 is closed, may operate the flow control device 160 to open the suction flow path 180.

[376] In other words, the controller 150, in response to receiving a stop command input when the flow control device 160 is in the closing position of the suction flow path 180 during operation, can maintain voltage supply to the flow control device 160 during the first standby time T _W1 from the time at which the stopping command is input, so that the suction flow path 180 opens. In this case, the first waiting time T _W1 may correspond to the time required to move the flow control device 160 from a position in which the suction flow path 180 is closed to a position in which the suction flow path 180 is open.

[377] Essentially, the controller 140 may stop supplying voltage to the suction device 150, so that the suction device 150 stops operating when the first time T _W1 has elapsed after inputting the command to stop the dust discharge operation, and when the voltage supply to the suction device 150 also stops stops supplying voltage to the flow control device 160, so that the suction device 150 and the flow control device 160 are turned off in a state in which the flow control device 160 opens the suction flow path 180.

[378] As described above, the controller 140 can control the suction device 150 and the flow control device 160 to stop operation by counting the first waiting time T _W1 , and can also control the suction device 150 and the flow control device 160 to stop operation by determining whether the a device 160 for adjusting the flow of the suction flow channel 180 based on the output value of the position detection sensor 130 .

[379] That is, the controller 140 can control the suction device 150 and the flow control device 160 to stop operation in accordance with the determination that the suction flow path 180 is open based on the output value of the position detection sensor 130 after a command to stop the dust discharge operation of the station 100 is input. unloading

[380] With this configuration, the controller 140 can prevent the suction flow path 180 from closing in a situation in which the suction fan 153 continues to rotate after the voltage supply to the suction device 150 is interrupted, thereby preventing noise from occurring.

[381] As described above, even without applying voltage to the suction device 150, the suction fan 153 may continue to rotate by inertia. Until the suction fan 153 is completely stopped after the voltage supply to the suction device 150 is stopped, the suction air flow in the suction flow path 180 may remain reduced. When the suction flow path 180 is closed by the flow control device 160 in a situation where the air pressure changes due to a change in the suction air flow, noise may be generated due to the instantaneous change in air pressure.

[382] Therefore, the controller 140, in response to receiving a command to stop the dust unloading operation after the dust unloading operation is initiated, can control the flow control device 160 to stop the operation in a state in which the flow control device 160 opens the suction flow path 180 so that closure is prevented suction flow path 180 in a situation in which the suction fan 153 continues to rotate after the voltage supply to the suction device 150 is interrupted, so that noise is prevented from occurring.

[383] In addition, the controller 140 in accordance with the embodiment, when a command to stop the dust discharge operation is input (YES at operation 2220) and the suction flow path 180 is open (NO at operation 2230), can control the flow control device 160 to stop Thereafter, the unloading station 100 of the cleaning device 1 can control the suction device 150 to stop operation when the first waiting time T _W1 has expired (YES in operation 2270) after inputting the stop command in operation 2280.

[384] That is, the controller 140 according to an embodiment, in response to receiving an input of a command to stop (stop) the dust discharge operation in a state in which the suction flow path 180 is open, may be able to stop the operation of the flow control device 160 so that so that the suction flow path 180 is maintained open by the flow control device 160.

[385] In other words, the controller 140, in response to receiving a stop command input when the flow control device 160 is in the open position of the suction flow path 180 during operation, may stop supplying voltage to the flow control device 160 to maintain the suction flow path 180 open. .

[386] With this configuration, the controller 140 can prevent the suction flow path 180 from closing in a situation in which the suction fan 153 continues to rotate after the power supply to the suction device 150 is stopped, so that noise is prevented from occurring.

[387] The discharge station 100 of the cleaning device 1 according to an embodiment can control the flow control device 160 to close the suction flow path 180 when the second waiting time T _W2 (for example, 2.5 seconds) has elapsed after stopping the operation of the flow control device 160 at operations 2290.

[388] As described above, the controller 140 completes the cycle by finally closing the suction flow path 180 upon inputting a command to stop the dust discharge operation, so that the suction device 150 is protected from foreign substances remaining in the suction flow path 180 and when the discharge operation is re-initiated foreign matter allows the suction device 150 to operate in a state in which the suction flow path 180 is open, so that noise is prevented from occurring.

[389] FIG. 23 is a flowchart showing a control method of the cleaning device 1, which shows a case in which the suction air flow rate is controlled by controlling the first motor 151 according to the embodiment of the disclosure.

[390] Referring to FIG. 23, the discharge station 100 of the cleaning device 1 according to an embodiment can determine whether the dust collection container 15 is connected to the discharge station 100 based on the output value of the sensor 110 in operation 2310.

[391] The discharge station 100 of the cleaning device 1 according to an embodiment can control the first motor 151 to turn on and then turn off when the dust collection container 15 is connected to the discharge station 100 (YES at 2320).

[392] That is, the controller 140 of the discharge station 100 can control the first motor 151 so that foreign substances in the dust collection container 15 are discharged when the dust collection container 15 of the vacuum cleaner 10 is connected to the discharge station 100.

[393] In detail, the controller 140 can determine whether the dust collection container 15 is connected to the unloading station 100 based on the output value of the sensor 110, and when the dust collection container 15 is connected to the unloading station 100, initiate control execution of the first motor 151.

[394] However, the controller 140 may additionally take into account the control command of the user input through the input device 120 in addition to the output value of the sensor 110 and initiate execution of control of the first motor 151 only if there is a command from the user.

[395] The discharge station 100 of the cleaning device 1 according to the embodiment, while the suction air flow is supplied to the dust collection container 15 by the suction fan 153 in accordance with the driving of the first motor 151, and the air in the dust collection container 15 is sucked, allows changing the suction air flow, thereby changing the air flow rate inside the dust collection container 15 and varying the air flow inside the dust collection container 15.

[396] For this purpose, the discharge station 100 of the cleaning device 1, when the dust collection container 15 is not separated (NO in operation 2340) and the number of times the first motor 151 is turned on does not reach a predetermined number of times (NO in operation 2350), may adjust at least one of the driving time of the first motor 151 or the rotation speed of the first motor 151 in operation 2360. Thereafter, the unloading station 100 of the cleaning device 1 can control the first motor 151 so that the first motor 151 is turned on and then turned off based on the adjusted actuation time and/or adjusted rotation speed in step 2330.

[397] As such, the controller 140, in order to supply uneven suction air flow to the dust collection container 15, can adjust at least one of the driving time or the rotation speed of the first motor 151 when the first motor 151 is repeatedly turned on/off.

[398] That is, the controller 140 may control the first motor 151 such that the first motor 151 is alternately turned on and off.

[399] In this case, the controller 140 may adjust the driving time of the first motor 151 by adjusting at least one of the time during which the first motor 151 is turned on or the time during which the first engine 151 is turned off whenever the first the motor 151 is switched on and off alternately.

[400] In addition, the controller 140 may adjust the rotation speed of the first motor 151 by adjusting the pulse width of the power supply voltage supplied to the first motor 151 whenever the first motor 151 is alternately turned on and off.

[401] In this case, the suction fan 153 can supply a suction air flow having a different suction power whenever the first motor 151 is alternately turned on and off in accordance with the change in the driving time of the first motor 151 or the rotation speed of the first motor 151, and since The internal pressure of the dust collection container 15 changes due to the uneven suction air flow, foreign substances in the dust collection container 15 can be smoothly discharged from the dust collection container 15.

[402] That is, since the air flow rate inside the dust collection container 15 changes, the air spreads in all directions in the space inside the dust collection container 15, and accordingly, the air flow inside the dust collection container 15 may change in various directions.

[403] Since the direction of the air flow changes instantaneously, some foreign substances that had resistance in a particular direction may lose resistance due to the air flow in another direction, and may be thrown out of the dust collection container 15 along with the air flow.

[404] That is, the controller 140 repeats the supply and interruption of the supply of suction air flow to the dust collection container 15 by controlling the on-off control of the first motor 151, and changes the supply time or suction power when supplying the suction air flow, thereby periodically changing the air flow inside the dust collection container 15. With this configuration, foreign substances from the dust collection container 15 can be discharged more efficiently.

[405] In accordance with an embodiment, the controller 140 may specify different pulse widths for the power supply voltage pulses within at least one of the time periods during which the first motor 151 is alternately turned on and off such that the first motor 151 vibrates.

[406] In this case, the first motor 151 may undergo a rapid change in rotation speed based on the pulse width difference between the power supply voltage pulses, and accordingly, the first motor 151 may vibrate.

[407] The vibration of the first motor 151 may be transmitted to the body of the discharge station 100 and the dust collection container 15 connected to the discharge station 100 . That is, the dust collection container 15 can vibrate in accordance with the vibration of the first motor 151, and foreign matter in the dust collection container 15 can be discharged more efficiently in accordance with the vibration.

[408] The discharge station 100 of the cleaning device 1 according to an embodiment may repeat the on/off control of the first motor 151 until the dust collection container 15 is separated from the discharge station 100 (YES at operation 1040) or the first motor 151 does not will be turned on a preset number of times (YES at operation 1050). In this case, the predetermined number of times may be set at the design stage of the cleaning device 1 or may be set by the user through the input device 120. However, the disclosure is not limited to this, and a predetermined number of times can be set by the controller 140 based on information about the amount of foreign substances collected in the dust collection container 15 obtained by a sensor or the like.

[409] The controller 140 according to an embodiment may drive the first motor 151 for a predetermined time that is set to collect foreign matter remaining in the suction flow path 180 by the collection 190 when the dust collection container 15 is connected to the discharge station 100 and then separated from the unloading station 100.

[417] In detail, the controller 140 controls the first motor 151 to turn on when the flow path valve 163 opens the suction flow path 180, and controls the first motor 151 to turn off when the flow path valve 163 closes the suction flow path 180.

[418] That is, the controller 140 controls the first motor 151 and the second motor 161 in conjunction with each other, thereby more efficiently supplying and re-supplying the suction air flow and preventing the suction fan 153 from causing noise due to rotation when the suction flow path 180 is closed, and reducing overload of the first engine 151.

[419] In this case, the controller 140 may control the second motor 161 so that the flow path valve 163 opens and closes the suction flow path 180 in a predetermined cycle, and may control the second motor 161 to match the driving time of the first motor 151, which changes whenever the first motor 151 is alternately turned on and off.

[420] That is, when the on time during which voltage is supplied to the first motor 151 or the off time during which voltage is not supplied to the first motor 151 changes, the controller 140 may control the second motor 161 to operate the channel valve 163 flow according to the changed on time and off time.
