Description

Apparatus and method for controlling operation of air conditioner
Technical Field
The present invention relates to an apparatus and method for controlling operation of an air conditioner.
Background
Generally, an air conditioner uses a refrigerating cycle of a refrigerant composed of a compressor, a condenser, an expansion mechanism, and an evaporator to cool and heat or purify air in a room in order to create a more pleasant indoor environment for a user.
The indoor units of the air conditioner may be classified into ceiling type, wall type, and vertical type according to the installation positions of the indoor units. In the vertical indoor unit, the discharge port may be formed on the front surface or the side surface of the casing, and the suction port may be formed on the rear surface of the casing.
As represented by a vertical indoor unit, a ceiling-mounted indoor unit or a wall-mounted indoor unit generally includes means for switching the discharge direction or air flow of air discharged through a discharge port.
In this regard, prior art document 1 (korean laid-open patent publication No. 10-2018-0089748) discloses an indoor unit of an air conditioner having a vane-shaped outer air guide for guiding air discharged through an outlet, and minimizing dew condensation on an outer surface by forming air holes penetrating an inner guide surface and the outer surface of the outer air guide.
However, in the air conditioner disclosed in prior art document 1, there is a considerable gap between the discharge direction or the air flow direction of the air discharged through the discharge port and the penetration angle of the air hole. In addition, since the air holes are formed in a microporous shape having a small sectional area, a considerable level of resistance is generated to the air flowing into the air holes. Further, there is a problem in that there is a high possibility that flow loss and noise are generated thereby, and there is a high possibility that the air hole is blocked due to fixation of a pollution source such as dust inside the air hole.
In addition, in the air conditioner disclosed in prior art document 1, since the penetration angle of the air hole is almost perpendicular to the outer surface, the air passing through the air hole passes through only the air hole, and the outer surface of the air guide cannot be cooled effectively. Therefore, the effect of reducing the temperature difference between the inner guide surface and the outer surface is expected to be very insufficient, and there is a problem that it is difficult to expect the dew condensation suppressing effect thereby.
In addition, prior art document 2 (korean laid-open patent publication No. 10-2017-0010293) discloses a door unit comprising: a door wing for opening and closing the opening; a door action part for moving the door wing panel forward or backward; and a control unit for controlling the air discharged from the opening to advance straight ahead of the opening or to be discharged radially from the opening by adjusting the distance between the door wing and the opening.
In addition, prior art document 3 (korean laid-open patent publication No. 10-2019-0106716) discloses an indoor unit of an air conditioner, which includes: a proximity sensor for measuring a distance of a user located in front of the door panel; and a rear cover which forms a proximity sensor hole for disposing a proximity sensor at one end and is disposed between the front glass and the display to maintain a space for disposing the proximity sensor.
However, prior art documents 2 and 3 do not disclose a structure for controlling changes in the direction, speed, and flow of air discharged from the side surface of an indoor unit of an air conditioner and directed to the front of the indoor unit.
Further, the air conditioner disclosed in the corresponding document discloses only the content of the discharged air, and does not disclose the content of controlling the movement of the direction of each of the plurality of blades of the discharged air.
Further, the air conditioner disclosed in the corresponding document discloses only the operation at the set temperature, and does not disclose the control of the movement of each of the plurality of blades in consideration of the human body adaptation time.
Therefore, it is necessary to control the direction of the discharged air by controlling the operation of each of the plurality of blades included in the indoor unit of the air conditioner. In addition, it is necessary to control the direction of the discharged air by controlling the movement of each of the plurality of blades in consideration of the human body adaptation time.

< door Assembly >
The door assembly II includes: a front door module 21 for opening and closing a front discharge port 141 formed in the front panel 14 and converting a direction of an air flow discharged through the front discharge port 141; side door modules 22 for opening and closing side discharge ports 224a, 224b formed on both side surfaces, respectively; and a vane module 23 for converting the direction of the air flow discharged through the side discharge ports 224a, 224 b.
The front door module 21 is provided to reciprocate in the front-rear direction between a rearmost position for closing a flow path of air discharged through the front discharge port and a foremost position for forming a forward airflow.
The operation mode in which the forward air flow is generated in a state in which the front door module 21 protrudes to the forefront position may be defined as a direct wind operation mode so as to be distinguished from an indirect wind operation mode described later.
Further, the front door module 21 may stop at an aligned position corresponding to a middle point between the rearmost position and the foremost position. The aligned position corresponds to a position where the outer panel 211 disposed on the forefront side of the front door module 21 is substantially horizontal to the front surface of the front panel 14.
When the front door module 21 is stopped at the aligned position, the air discharged through the front discharge port 141 forms a side air flow discharged from the front discharge port 141 to the outside in the radial direction instead of being discharged to the front due to the shape of the outer surface of the front door module 21. This mode of operation may be defined as an indirect wind mode of operation.
On the other hand, the outer panel 211 disposed at the forefront side of the front door module 21 is formed of a translucent material, and light generated by a display unit (not shown) disposed inside thereof may be irradiated to the outside through the outer panel 211. Accordingly, the outer panel 211 of an embodiment of the present invention may be used as a display for providing information about the operation state of the indoor unit 1, the air quality state around the indoor unit 1, and the like to the user.
The side door module 22 opens and closes side discharge ports 224a and 224b formed in both side surfaces of the housing i.
That is, the side door module 22 is configured to close the side discharge ports 224a and 224b in a state where the side air blowing modules 32a, 32b, and 32c are not operated, for example, in a state where the operation of the entire indoor unit 1 is interrupted and in a state where only the front air blowing module 31 of the indoor unit 1 is operated.
As described above, in the state where the side air blowing modules 32a, 32b, and 32c are not operated, the side air outlets 224a and 224b are closed by the side door module 22, and thus, inflow of dust and the like into the inside of the side air blowing modules through the side air outlets 224a and 224b and fixation of the dust and the like into the inside of the side air blowing modules or inflow of foreign matters and the like which may cause a failure can be effectively prevented.
The side door module 22 may include: a pair of side gates 221a and 221b that move in the front-rear direction (F-R direction) and open and close side discharge ports 224a and 224b; side door driving units 222a and 222b for generating driving force for the side doors 221a and 221 b; and a pair of support frames 223a, 223b for supporting the respective side doors 221a, 221b and the side door driving parts 222a, 222b.
The side gates 221a and 221b are supported so as to be movable from the foremost position where the side discharge ports 224a and 224b are completely closed to the rearmost position where the side discharge ports 224a and 224b are completely opened. As shown in fig. 1 to 3a, the side doors 221a, 221b extend from the upper end to the lower end of the case i and cover the whole thereof with a predetermined width, and the outer surfaces of the side doors 221a, 221b may be configured to have a material and shape capable of forming the same texture as the rear upper case 11 and the front panel 14 so as to be capable of forming an aesthetic feeling for a user and an integral feeling with the front panel 14 and the rear upper case 11.
For the movable support of the side doors 221a, 221b, a guide connector (not shown) may be further provided, one end of which is attached to the side doors 221a, 221b and the other end of which is slidably and movably supported to the support frames 223a, 223b.
Illustratively, the side door driving parts 222a, 222b may include a gear motor, a pinion gear connected to an output shaft of the gear motor, and a rack gear converting a rotational force of the pinion gear into a linear reciprocating motion so that the side doors 221a, 221b can be driven in an electric manner.
The gear motor is firmly fixed to the support frames 223a, 223b corresponding to the fixing members, and the rack engaged with the pinion gear may be firmly fixed to the inner side surfaces of the side doors 221a, 221b.
On the other hand, as described above, the side doors 221a, 221b are provided in a shape extending from the upper end to the lower end of the housing i. Accordingly, the height of the side gates 221a, 221b is very large with respect to the width thereof, and thus it is difficult to efficiently drive the respective side gates 221a, 221b only by a single driving part.
Accordingly, two side door driving parts 222a, 222b are provided for the individual side doors 221a, 221b, respectively, and as shown, they are preferably disposed at positions adjacent to the upper and lower ends of the respective side doors 221a, 221b, respectively.
The support frames 223a, 223b rotatably support the side doors 221a, 221b and form a part of both side surfaces of the case i together with the rear upper case 11 and the rear lower case 13. In more detail, the support frames 223a, 223b may be disposed between the rear upper case 11 and the front panel 14.
The support frames 223a and 223b have side discharge ports 224a and 224b extending in the up-down direction (U-D direction).
As shown, a plurality of side vanes 225a, 225b for guiding the direction of the discharged air may be disposed at the side discharge ports 224a, 224b.
The plurality of side blades 225a, 225b may be integrally formed with the support frames 223a, 223 b. The plurality of side blades 225a and 225b according to an embodiment of the present invention are disposed and fixed to be inclined forward, so that air discharged to the outside of the case can be guided in the forward direction. Accordingly, in a state where the vane module 23 described later is not active, the air discharged through the side discharge ports 224a, 224b forms a forward air flow through the plurality of side vanes 225a, 225b.
On the other hand, blades configured to perform the same function as the side blades 225a, 225b provided to the support frames 223a, 223b may be formed on other members than the support frames 223a, 223 b. For example, side blades may be integrally formed on the side surfaces of the discharge guides 326a, 326b, 326c of the side air blowing modules 32a, 32b, 32c described later.
Of course, as shown in fig. 3a, the side blades 225a and 225b may be provided on the support frames 223a and 223b, and the side blades 3261 may be provided on the discharge guides 326a, 326b, and 326 c.
The vane module 23 serves to convert the forward airflow discharged through the side discharge ports 224a, 224b into the side airflow.
As described above, the air discharged to the side discharge ports 224a, 224b forms a forward air flow by the side blades 225a, 225b of the support frames 223a, 223b or the side blades 3261 of the discharge guides 326a, 326b, 326 c.
The vane module 23 functions as a vane for converting the direction of the forward air flow as described above. The direction change of the forward air flow is achieved by the plate-shaped vanes 231a and 231b disposed adjacent to the front side of the side discharge ports 224a and 224b as shown in fig. 3 a.
In more detail, when the side air blowing modules 32a, 32b, 32c are operated in the direct wind mode forming the forward air flow, the blades 231a, 231b of the blade module 23 remain hidden in the storage position on the rear side of the front panel 14 or in the hidden state. Therefore, the vanes 231a, 231b do not affect the flow of the air discharged through the side discharge ports 224a, 224b, and the discharged air remains as a forward flow.
However, when the blade driving part (not shown) is operated to switch from the direct wind mode to the indirect wind mode, the blades 231a, 231b start to horizontally move from the above-described storage position toward the direction of exposure to the outside.
When the horizontal movement starts, the blades 231a, 231b stop after moving to the final deployed position.
When the blades 231a and 231b are moved to the final extended position, the air discharged through the side discharge ports 224a and 224b receives the resistance of the blades 231a and 231b, and in particular, the air passing through the front end sides of the side discharge ports 224a and 224b directly collides with the blades 231a and 231b and is converted in moving direction.
At this time, since the flow velocity of the air passing through the front end side is the fastest among the air discharged through the side discharge ports 224a, 224b, the air colliding with the blades 231a, 231b and being converted in moving direction affects the moving direction of the air discharged from the rear side. As a result of this effect, the direction of movement of the air passing through the side discharge ports 224a, 224b is entirely changed, and a side air flow is formed.
Fig. 3a shows an embodiment in which one left blade 231a and one right blade 231b are provided corresponding to the left discharge port 224a and the right discharge port 224b, respectively. However, the present invention is not limited thereto, and it is considered that a modification in which the left side blade 231a and the right side blade 231b are respectively divided into a plurality of settings is also possible. For convenience, the following description will be made based on an embodiment in which one vane 231a, 231b is provided on the left and right sides, respectively, and a specific structure of the vanes 231a, 231b will be described later with reference to fig. 4 a.
The blade driving part (not shown) may include a gear motor, a pinion (not shown) connected to an output shaft of the gear motor, and a rack (not shown) converting a rotational force of the pinion into a linear reciprocating motion so as to be able to electrically drive the blades 231a, 231b.
The gear motor is configured to be firmly supported on another bracket (not shown), and a rack engaged with the pinion may be integrally formed with the blades 231a, 231b, or separately formed and attached to the blades 231a, 231b. As will be described later, a plurality of fastening holes 231h may be formed in the blades 231a, 231b such that racks may be attached to a plurality of the fastening holes 231h using fastening means such as bolts.

The module case 40 may be provided in a shape suitable for mounting respective components constituting the front door module 21 and the front air supply module 31.
The front door module 21 may include a first ring 214, a first cylinder 215, a first motor 216, a planetary gear arrangement 217, a support plate 218, a carrier housing 2191, and a second ring 2192.
The first ring 214 may be rotated by receiving a driving force from the first motor 216. The first ring 214 is coupled with the first cylinder 215, and as the first ring 214 rotates, the first cylinder 215 may move along a linear path in the front-rear direction of the front assembly, i.e., the front-rear direction of the indoor unit.
The first ring 214 is integrally formed in a ring shape, and the first cylinder 215 may be installed at an outer circumference of the first ring 214 to move in a front-rear direction with rotation of the first ring 214. The first ring 214 is mounted to a support plate 218 and may be configured to rotate but not move in a fore-aft direction.
A first cylinder 215 may be provided to be installed at an outer circumference of the first ring 214 and coupled to the first ring 214 to move in a front-rear direction as the first ring 214 rotates.
An air guide ring is coupled to the front portion of the first cylinder 215, and the second ring 2192 moves in the front-rear direction along with the movement of the first cylinder 215, so that the front discharge port 141 is opened and closed as shown in fig. 3c and 3f, and the opening degree (opening rate) of the front discharge port 141 can be adjusted.
The first motor 216 may receive power from a power source to provide driving force to the first ring 214. The rotation and stop operation of the first motor 216 may be controlled by a control unit provided in the air conditioner. The first motor 216 may be stably mounted to the support plate 218.
The planetary gear device 217 may be coupled to a rotation shaft of the first motor 216, and transmit a driving force of the first motor 216 to the first ring 214. At this time, the planetary gear device 217 may input a driving force through the rotation shaft of the first motor 216, and output the driving force from the first ring 214.
A support plate 218 is associated with the first ring 214 and may house the first motor 216 and the planetary gear arrangement 217. The first motor 216 is mounted to a support plate 218, and can transmit driving force to a planetary gear device 217 through a rotation shaft.
The first ring 214, the first cylinder 215, and the support plate 218 may be installed in the carrier housing 2191. The carrier housing 2191 itself may remain stationary without rotating or moving in a front-to-back direction.
At this time, the first ring 214 mounted to the carrier housing 2191 may rotate with respect to the carrier housing 2191 as the first motor 216 rotates. The first cylinder 215 attached to the carrier housing 2191 is linearly movable in the front-rear direction with respect to the carrier housing 2191 in response to the rotation of the first motor 216.
A second ring 2192 may be coupled to a front portion of the first cylinder 215. The second ring 2192 may be mounted to the first cylinder 215 to move in a front-to-back direction relative to the carrier housing 2191 as the first cylinder 215 moves in the front-to-back direction.
Of course, a display illumination unit 210 described later may be coupled to the front portion of the first cylinder 215 to move in the front-rear direction together with the first cylinder 215. That is, the first cylinder 215, the second ring 2192, and the display illumination unit 210 may move together in the front-rear direction of the front assembly.
The front door module 21 further includes a display lighting unit 210 for display and lighting, and the display lighting unit 210 may have an inner panel 213, a printed circuit board 212, and an outer panel 211.
The inner panel 213 may be coupled to the first cylinder 215 to linearly move in the front-rear direction together with the first cylinder 215. A printed circuit board 212 is accommodated in the inner panel 213, and may have circuits for electrical operation, various active elements, and passive elements.
The outer panel 211 may be coupled to the inner panel 213, disposed in front of the inner panel 213, electrically connected to the printed circuit board 212, and having a display portion 211a.
All or a part of the front surface of the outer panel 211 may be provided as the display portion 211a. The display unit 211a may display characters, graphics, and the like indicating the operation state of the air conditioner. On the other hand, an input unit through which a user inputs a command for controlling the operation of the air conditioner may be provided on the front surface of the outer panel 211.
The front air supply module 31 may include a front air supply fan 311, a fan housing 313, a first control blade 315, a front Fang Songfeng motor 312, a second control blade 316, and a diffuser 317.
The front blower fan 311 receives a driving force from the front blower motor 312 and rotates, thereby forcing air to flow to the front discharge port 141. Since the front discharge port 141 is provided in a ring shape, it is preferable that the front Fang Songfeng fan 311 is provided to form an air flow shape and a flow path corresponding to the shape of the front discharge port 141.
To this end, as shown in FIG. 3c, the front blowing fan 311 may include a fan hub 3111, a shroud 3112 and vanes 3113.
The fan hub 3111 may be integrally formed to be gradually curved in a forward direction of the front assembly as going from a central portion to an edge of the front blower fan 311.
The shroud 3112 is spaced apart from the fan hub 3111 and disposed rearward of the fan hub 3111, and may form a flow path of air together with the fan hub 3111. The hood 3112 may be integrally formed to be curved in a forward direction of the front assembly as going from a central portion to an edge of the front blower fan 311.
The fins 3113 are used to connect the fan hub 3111 and the shroud 3112, and may be provided in plural. The fins 3113 may be radially arranged at predetermined intervals in the circumferential direction of the front blower fan 311.
By forming the fan hub 3111 and the shroud 3112 in the above-described structure, the front blower fan 311 can form an air flow shape and a flow path corresponding to the annular discharge port.
The front blower fan 311 is mounted in the fan housing 313, and the flow of air flowing from the front blower fan 311 to the front discharge port 141 can be guided. In the fan housing 313, an inner sidewall forming an inner circumferential surface and an outer sidewall forming an outer circumferential surface may be spaced apart from each other in a diameter direction to form a flow space.
The air may have a flow shape and a flow path corresponding to the annular shape of the front discharge port 141 through the flow space.
The first control blade 315 is disposed in front of the front blower fan 311, and can change the flow direction of the air flowing in from the front blower fan 311. The second control blade 316 is disposed in front of the first control blade 315, and can change the flow direction of the air flowing in from the first control blade 315.
The first control vane 315 and the second control vane 316 may be integrally provided in a ring shape to correspond to the ring shape of the front spouting port 141. As the air passes through the first control blade 315 and the second control blade 316, the linearity of its flow path (stream line) in the front-rear direction can be increased.
The air passing through the flow space of the fan housing 313 collides with the inner and outer sidewalls of the fan housing 313 forming the flow space, so that a component of its flow in the front-rear direction may be reduced. When such air passes through the first control blade 315 and the second control blade 316, the amount of air that is directly going to the front portion of the front assembly increases, and thus, the flow path of air increases linearly in the front-rear direction, so that it can be discharged to the front discharge port 141.
The front air supply motor 312 may be disposed at a central portion of the first control blade 315, and a rotation shaft may be coupled to the front air supply fan 311. The front blower motor 312 may receive power from a power source and operate to rotate the front blower fan 311.
In order to fix the front Fang Songfeng motor 312 to the first control blade 315, a motor support 312a may be provided at the front assembly, the front blowing motor 312 is mounted to the motor support 312a, and the motor support 312a itself is disposed at a central portion of the first control blade 315 and coupled to an inner sidewall of the first control blade 315.
A diffuser 317 may be disposed forward of the second control vane 316 and forms the forward discharge port 141 together with the second ring 2192. The diffuser 317 forms an outer peripheral surface of the front discharge port 141, and the second ring 2192 forms an inner peripheral surface of the front discharge port 141, so that the front discharge port 141 may be integrally provided in a ring shape by the diffuser 317 and the second ring 2192.
Fig. 3e is a perspective view showing a state in which the front discharge port 141 is opened in fig. 3 b. Fig. 3f is a cross-sectional view of fig. 3 e.
The second ring 2192 may include a main body portion 2192a and an air guide portion 2192b. The body portion 2192a is coupled to the first cylinder 215, and may be provided in a ring shape. Accordingly, the main body portion 2192a can move in the front-rear direction of the front assembly with the movement of the first cylinder 215.
The air guide portion 2192b is formed to protrude from the outer periphery of the main body portion 2192a and is provided in a ring shape, and is movable in the front-rear direction along with the movement of the first cylinder 215 to open and close the front discharge port 141 or to change the direction of the air flow.
The air guide 2192b forms an inner circumferential surface and the diffuser 317 forms an outer circumferential surface to form the front discharge port 141, and thus, the front discharge port 141 may be entirely provided in a ring shape.
Referring to fig. 3c, when the first cylinder 215 moves toward the rear of the front assembly, the air guide 2192b also moves rearward together with the first cylinder 215, so that the width of the front discharge port 141 becomes narrow, and eventually the front discharge port 141 can be closed.
Referring to fig. 3f, when the first cylinder 215 moves forward of the front assembly, the air guide 2192b also moves forward together with the first cylinder 215, so that the front discharge port 141 can be opened. In a state where the first cylinder 215 is advanced to the maximum extent, the width of the front discharge port 141 may be maximized, and at this time, the opening degree of the front discharge port 141 may be maximized.
A first coupling portion 2153 may be formed at an inner circumference of the first cylinder 215, and the first coupling portion 2153 protrudes in a diameter direction of the first cylinder 215 and is provided with a first through hole 2153a. The inner panel 213 may have a second coupling portion 2131 formed on an inner periphery thereof, and the second coupling portion 2131 may protrude in a diameter direction of the inner panel 213 and may have a second through hole 2131a corresponding to the first through hole 2153a.
The first and second combining portions 2153 and 2131 may be provided in plural numbers, and in this case, the number of the first and second combining portions 2153 and 2131 may be the same. The inner panel 213 may be coupled to the first cylinder 215 by fastening a coupling mechanism such as a bolt into the first through hole 2153a and the second through hole 2131 a.
Accordingly, the inner panel 213 can be moved in the front-rear direction of the front assembly together with the first cylinder 215. At this time, the second ring 2192 disposed between the inner panel 213 and the first cylinder 215 is movable in the front-rear direction.
< detailed Structure of blade >
Hereinafter, a detailed structure of the blades 231a, 231b according to an embodiment of the present invention will be described with reference to fig. 4a to 10.
As described above, the vanes serve to convert the forward airflow discharged through the side discharge ports 224a, 224b into the side airflow.
As shown in fig. 4a to 5, the blades 231a, 231b include: a left blade 231a disposed adjacent to the front of the left discharge port 224 a; and a right blade 231b disposed adjacent to the front of the right discharge port 224 b.
The left side blades 231a and the right side blades 231b are configured to have the same shape, and may be alternately arranged without distinguishing between left and right.
The blades 231a, 231b have a rectangular shape with a vertical direction length Lv much greater than a horizontal direction width Wv. The vertical length Lv may be determined to be a value that enables the entire side discharge ports 224a, 224b to be covered from the front. That is, the vertical length Lv is set to be equal to or greater than the vertical or vertical length of the side discharge ports 224a, 224 b.
The blades 231a and 231b have a plate shape with a constant thickness as a whole.
On the other hand, at least one through slit 2313a, 2313b is formed at a position adjacent to the outer end surface of the vane 231a, 231b corresponding to the outer side with respect to the center of the indoor unit 1, and at least one through slit 2313a, 2313b extends in the longitudinal direction of the vane 231a, 231b and in parallel with the outer end surface.
The through slits 2313a, 2313b penetrate from the front surface portions of the blades 231a, 231b and extend to the rear surface portions, and serve as air passages through which at least a part of the air discharged from the side discharge ports 224a, 224b passes as will be described later.
Illustratively, the through slits 2313a, 2313b may include: the first slits 2314a, 2314b are formed adjacent to and extending parallel to the outer end surfaces of the blades 231a, 231 b; and second slits 2315a, 2315b formed parallel to the first slits 2314a, 2314b and formed to be spaced inward with respect to the first slits 2314a, 2314 b.
However, the present invention is not limited thereto, and the following description will be exemplarily based on an embodiment in which the first slits 2314a, 2314b and the second slits 2315a, 2315b are disposed in parallel in the length direction of the blades 231a, 231 b.
The first slits 2314a, 2314b and the second slits 2315a, 2315b are formed in long hole shapes having horizontal direction widths WH1, WH2 that are much smaller than vertical direction lengths Ws1, ws 2. Therefore, unlike the prior art in which the micropore-shaped air holes are applied, the resistance to air passing through can be reduced, and there is an effect in that the possibility that the air passage is blocked by dust or the like is significantly reduced.
In addition, in order to increase the effect of reducing the resistance of the air passing through the first and second slits 2314a, 2314b and 2315a, 2315b, the sectional areas of the first and second slits 2314a, 2314b and 2315a, 2315b remain constant. Since the cross-sectional areas of the first slits 2314a, 2314b and the cross-sectional areas of the second slits 2315a, 2315b remain constant, the sizes of the front and rear openings of the first slits 2314a, 2314b remain the same, and the sizes of the front and rear openings of the second slits 2315a, 2315b remain the same.
Further, the shapes and sizes of the first slits 2314a, 2314b and the second slits 2315a, 2315b are preferably the same. That is, the vertical length Ws1 of the first slits 2314a, 2314b and the vertical length Ws2 of the second slits 2315a, 2315b may be formed to be identical to each other, and the horizontal width WH1 of the first slits 2314a, 2314b and the horizontal width WH2 of the second slits 2315a, 2315b may be formed to be identical to each other.
Thereby, the air flow rate passing through the first slits 2314a, 2314b is maintained almost the same as the air flow rate passing through the second slits 2315a, 2315b, so that the local temperature difference of the front surface portions of the blades 231a, 231b can be minimized.
In fig. 4a and 5, the vertical direction position at which the first slits 2314a, 2314b are formed and the vertical direction position at which the second slits 2315a, 2315b are formed may be set to be the same. However, this is merely an example, and a configuration in which the vertical direction positions at which the first slits 2314a, 2314b are formed and the vertical direction positions at which the second slits 2315a, 2315b are formed are different from each other, that is, a configuration in which the first slits 2314a, 2314b and the second slits 2315a, 2315b are offset from each other in the horizontal direction is also applicable. For convenience, the following description is made based on the illustrated embodiments.
On the other hand, as described above, the blades 231a, 231b are provided so as to be horizontally movable from the storage position in a state of being hidden entirely on the rear surface of the front panel to the deployed position.
However, in the deployed position, the hidden blades are in a state of being partially exposed to the outside of the housing, and preferably, are moved to a flow path in which the rear openings of the first slits 2314a, 2314b and the rear openings of the second slits 2315a, 2315b are entirely exposed to the air discharged through the side discharge ports 224a, 224b with reference to the rear portions of the blades 231a, 231 b. Accordingly, as shown in FIG. 5, the back surfaces of the blades 231a, 231b may be divided into an exposed region 2312a-1 and a non-exposed region 2312a-2. Details regarding the exposed region 2312a-1 will be described later with reference to fig. 8.
Referring to fig. 4b, the blade 23 may include a cover bracket 232, a control blade 231, a blade driving part 233, and a mounting housing 234.
A cover bracket 232 may be coupled to the housing i. The cover bracket 232 is coupled to an inner side surface of the front panel 14 by, for example, bolts or the like, and the vane 231 may be mounted to the cover bracket 232 to move relative to the cover bracket 232.
The vane 231 is mounted to the cover bracket 232, and may be provided to be movable in a lateral direction of the cover bracket 232. The vane 231 is disposed in front of the side discharge port 224, and the vane 231 partially overlaps the side discharge port 224 in the front-rear direction of the housing i depending on the position where it moves in the lateral direction of the cover holder 232, and the overlapping area thereof can be changed. The vane 231 may be formed in a slit-free structure.
Accordingly, the flow direction of the air of the forward air flow discharged from the side discharge port 224 may be changed differently with a change in the overlapping area of the side discharge port 224 and the vane 231.
The blade driving part 233 is mounted to the cover bracket 232, and can move the blade 231 in a lateral direction of the cover bracket 232. The mounting housing 234 may accommodate at least a portion of the blade driving part 233 and mount it to the cover bracket 232.
The vanes 231 are provided in plural, and the movement of each of the vanes 231 can be independently controlled. As shown in fig. 4b, the blades 231 may be provided in plural in the up-down direction of the housing i.
For example, the blades 231 may be provided in two in the up-down direction of the housing i. However, the number of the blades 231 is not limited thereto, and may be set to three or more. At this time, the blade driving part 233 and the mounting housing 234 may be provided in the same number as the number of blades 231.
Since the vane 23 is provided as a pair on both sides of the housing i, the vane 231 may be provided on the left and right sides of the housing i, respectively. Therefore, when the blades 231 are provided in two in the up-down direction of the housing i, the blades 231 may be provided in total in four.
At this time, each of the blades 231 may be provided to operate independently of each other. The operation of each vane 231 can be independently controlled by a control unit provided in the air conditioner.
In the embodiment shown in fig. 4b, a total of four vanes 231 operate independently of each other, so that, for example, the moving positions of the four vanes 231 in the side direction of the housing i can be different from each other, and thus, the overlapping areas of the vanes 231 and the side discharge ports 224 in the front-rear direction of the housing i can be different from each other.
With this structure, the indoor unit of the air conditioner can individually control the plurality of blades 231 such that the moving positions of the respective blades 231 in the side direction of the casing i are different from each other, thereby forming various forms of flow directions of air in the room.
< action of blade >
Hereinafter, the operation of the blades 231a and 231b according to an embodiment of the present invention will be described with reference to fig. 6 to 9.
First, referring to fig. 6, in a state where the blades 231a, 231b are hidden in the storage position on the rear surface side of the front surface panel, the blades 231a, 231b do not affect the air flow of the air passing through the side discharge ports 224a, 224 b.
Therefore, when the side doors 221a and 221b move rearward and the side discharge ports 224a and 224b are completely opened, the heat exchange is completed by the heat exchanger, and the air flow Fm of the air pressurized and discharged by the side blower motor and the side blower fan is formed into a forward air flow forward by the side blades 225a and 225 b. That is, the state shown in fig. 6 is in a state of operating in the direct wind mode.
In the direct wind mode as described above, when it is necessary to convert the flow of air into a lateral flow, the blades 231a, 231b are horizontally moved from the above-described storage position to the deployed position.
That is, the left blade 231a moves horizontally in the left direction (Le direction) to the deployed position, and the right blade 231b moves horizontally in the right direction (Ri direction).
As described above, when the movement of the left and right blades 231a and 231b to the respective extended positions is completed, as shown in fig. 7, the air flow direction of the air flow Fm of the air discharged through the left discharge port 224a is switched to the left by the left blade 231a, and the air flow direction of the air flow Fm of the air discharged through the right discharge port 224b is switched to the right by the right blade 231 b.
That is, the air discharged through the side discharge ports 224a and 224b receives the resistance of the respective blades 231a and 231b, and in particular, the air passing through the front end sides of the side discharge ports 224a and 224b directly collides with the blades 231a and 231b and is converted in moving direction, and the flow of the discharged air is changed as a whole, so that the operation state of the indoor unit 1 is converted from the direct wind mode to the indirect wind mode.
However, fig. 7 shows a state in which both the left side blade 231a and the right side blade 231b are horizontally moved to the deployed position, but in contrast, it may be configured to move only either one of the left side blade 231a and the right side blade 231b to the deployed position. That is, the left and right blades 231a and 231b may be independently driven, respectively, so that it is controlled that either one side forms a forward air flow and the other side forms a side air flow.
On the other hand, when operating in the cooling operation, air having a temperature lower than that of the indoor air is discharged through the side discharge ports 224a, 224b, and the discharged air reduces the temperature of the rear surfaces of the deployed blades 231a, 231b to the temperature level of the discharged air.
Therefore, due to the temperature difference between the front and rear surfaces of the blades 231a and 231b, the condensation phenomenon is highly likely to occur in the front surface.
The through slits 2313a, 2313b penetrating and extending between the front and rear surfaces of the blades 231a, 231b serve to flow at least a part of the air flow Fs of the discharged air toward the front surfaces of the blades 231a, 231b to minimize the temperature difference.
In order to allow at least a part of the air flow Fs in the air flow Fm of the discharged air to be introduced into the through slits 2313a, 2313b effectively without flow loss, as shown in fig. 8, in the deployed position, the rear surface openings of the first slits 2314a, 2314b and the rear surface openings of the second slits 2315a, 2315b are entirely exposed to the flow path of the air discharged through the side discharge ports 224a, 224b, with reference to the rear surface portions of the blades 231a, 231 b. That is, the first slits 2314a and 2314b and the second slits 2315a and 2315b are integrally disposed in the exposed area 2312a-1.
At this time, the side discharge ports 224a, 224b are at least partially blocked by the exposed areas 2312a-1 of the vanes 231a, 231b when viewed from the front of the front panel.
With the above-described structure, the side air flow is formed by the exposed areas 2312a-1 of the blades 231a, 231b, and the exposed areas 2312a-1 in the flow path through which the cool air is discharged are minimized, so that the area in the front portions of the blades 231a, 231b where condensation is likely can be minimized.
However, as shown in fig. 8, of the horizontal width Wd of the side discharge ports 224a, 224b, the horizontal width W1 of the portion where the discharge port is blocked by the exposed region 2312a-1 is preferably larger than the horizontal width Wd1 of the portion where the discharge port is not blocked by the exposed region 2312a-1, and more specifically, is preferably 2 times or more the horizontal width Wd1 of the portion where the discharge port is not blocked by the exposed region 2312a-1, so that the side air flow is effectively formed.
On the other hand, as described above, an object of the present invention is to minimize a gap between a discharge direction or an air flow direction of air discharged through the side discharge ports 224a, 224b and an inclination angle of the through slits 2313a, 2313b formed in the blades 231a, 231b to minimize flow loss and generation of noise.
However, the side discharge ports 224a and 224b of the indoor unit 1 according to the embodiment of the present invention are formed at positions adjacent to the front panel, that is, at the rear side of the front panel.
Accordingly, as shown in fig. 8, the plurality of side blades 225a, 225b disposed at the side discharge ports 224a, 224b are inclined at a predetermined third inclination angle a3 with respect to the horizontal direction (Ri-Le direction) so that the air discharged from the side discharge ports 224a, 224b forms a forward air flow.
That is, based on fig. 8, the left side blade 225a has a front guide surface 2251a and a rear guide surface 2252a formed in parallel with each other, and the front guide surface 2251a and the rear guide surface 2252a form a third inclination angle a3 with the front surface 2311a of the left side blade 231 a.
The inclination angle a1 of the first slit 2314a and the inclination angle a1 of the second slit 2315a of the left blade 231a are formed corresponding to the third inclination angle a3 of the left blade 225 a.
More specifically, the first slit 2314a of the left blade 231a has a first inner wall surface WF1 extending parallel to the outer end surface 2316a and a second inner wall surface WF2 formed parallel to the first inner wall surface WF1, and the first inner wall surface WF1 and the second inner wall surface WF2 form a first inclination angle a1 with the front surface 2311a of the left blade 231 a.
Further, the second slit 2315a of the left blade 231a has a third inner wall surface WF3 extending parallel to the outer end surface 2316a and a fourth inner wall surface WF4 formed parallel to the third inner wall surface WF3, and the third inner wall surface WF3 and the fourth inner wall surface WF4 form a second inclination angle a2 with the front surface 2311a of the left blade 231 a.
At this time, the first inclination angle a1 and the second inclination angle a2 are each configured to form substantially the same angle as the third inclination angle a3 of the left-side blade 225 a.
Accordingly, the discharge direction or the air flow direction of the air discharged through the left side discharge port 224a substantially coincides with the inclination angles a1, a2 of the first slit 2314a and the second slit 2315a formed in the left side blade 231a, so that a part of the air passing through the left side discharge port 224a can be effectively introduced into the first slit 2314a and the second slit 2315a and the flow resistance can be minimized.
Further, the blades 231a, 231b of an embodiment of the invention further comprise means for effectively cooling the front portions of the blades 231a, 231b by introducing an air flow into the back openings of the first slits 2314a, 2314b and the back openings of the second slits 2315a, 2315b to minimize the temperature difference between the front and back portions.
When this is described with reference to fig. 9, as shown in the enlarged partial view of the left blade 231a shown in fig. 9, the corners of the front opening H11 and the rear opening H12 of the first slit 2314a and the corners of the front opening H21 and the rear opening H22 of the second slit 2315a are respectively formed as curved surfaces having a predetermined curvature.
In more detail, a corner H11e1 formed by the first inner wall surface WF1 of the first slit 2314a and the front surface portion 2311a of the left blade 231a meeting is formed as a curved surface having a first curvature R1, and a corner H22e1 formed by the first inner wall surface WF1 of the first slit 2314a and the rear surface portion 2312a of the left blade 231a meeting is formed as a curved surface having a second curvature R2 smaller than the first curvature R1.
Similarly, a corner H11e2 formed by the meeting of the second inner wall surface WF2 of the first slit 2314a and the front surface portion 2311a of the left blade 231a is formed as a curved surface having the second curvature R2, and a corner H22e2 formed by the meeting of the second inner wall surface WF2 of the first slit 2314a and the rear surface portion 2312a of the left blade 231a is formed as a curved surface having the first curvature R1.
The same applies to the second slit 2315a.
That is, the corner H21e1 formed by the meeting of the third inner wall surface WF3 of the second slit 2315a and the front surface portion 2311a of the left blade 231a is formed as a curved surface having the same first curvature R1 as the first slit 2314a, and the corner H22e1 formed by the meeting of the third inner wall surface WF3 of the second slit 2315a and the rear surface portion 2312a of the left blade 231a is formed as a curved surface having the same second curvature R2 as the first slit 2314 a.
The corner H21e1 formed by the meeting of the fourth inner wall surface WF4 of the second slit 2315a and the front surface portion 2311a of the left blade 231a is formed as a curved surface having the second curvature R2 identical to that of the first slit 2314a, and the corner H22e2 formed by the meeting of the fourth inner wall surface WF4 of the second slit 2315a and the rear surface portion 2312a of the left blade 231a is formed as a curved surface having the first curvature R1 identical to that of the first slit 2314 a.
As described above, by forming curvatures at the corners of the back surface openings H12, H22 of the first and second slits 2314a, 2315a, resistance to inflow of air is minimized, so that the air flow Fs can be effectively introduced into the first and second slits 2314a, 2315a.
Further, by making the first curvature R1 of the corners formed at the front openings H11, H21 of the first and second slits 2314a, 2315a, in particular, the outer corners H11e1 of the front opening H11 of the first slit 2314a and the outer corners H21e1 of the front opening H21 of the second slit 2315a larger than the second curvature R2, the air flow Fs passing through the front openings H11, H21 smoothly passes over the corners while moving in the left direction along the front portion 2311a of the left blade 231 a.
Accordingly, the air flow Fs passing through the first and second slits 2314a and 2315a can effectively cool the front surface portion 2311a of the left side blade 231a, with the effect that the temperature difference between the front surface portion 2311a and the rear surface portion 2312a is minimized.
The structure of reducing the air flow resistance by forming curved surfaces at the corners as described above can also be applied to the outer end surfaces 2316a of the blades 231a, 231 b.
Referring to fig. 9, a corner 2316a-2 formed by the outer end surface of the left blade 231a, that is, the left end surface 2316a and the front surface 2311a meeting each other may be formed as a curved surface having the same second curvature R2 as the first slit 2314a and the second slit 2315 a.
In addition, the corner 2316a-2 formed by the outer end surface 2316a of the left blade 231a, that is, the left end surface and the rear surface 2312a meeting each other may be formed as a curved surface having the same first curvature R1 as the first slit 2314a and the second slit 2315 a.
On the other hand, the blades 231a, 231b of the indoor unit 1 according to an embodiment of the present invention further include means for preventing water drops or dew, which may be generated at the front surface portion, from flowing down due to gravity.
When described with reference to fig. 10, a plurality of horizontal grooves that are recessed from the front surface portion by a predetermined depth and extend in the horizontal direction are provided in the front surface portion 2311a of the left blade 231a in which condensation is likely to occur.
The plurality of horizontal grooves serve as a kind of collector or pocket that prevents dew water that may be generated at the front surface portion 2311a of the left side blade 231a from moving in the gravity direction or the vertical direction.
Such a horizontal groove is preferably arranged in a region where dew condensation is highly likely to occur.
That is, based on the left blade 231a shown in fig. 8 to 9, a horizontal groove HG may be provided in a region where the front surface 2311a of the left blade 231a, i.e., the extended position, is directly exposed to the outside and condensation is highly likely to occur.
In more detail, the horizontal grooves HG may be formed entirely or partially in the region between the front opening H11 of the first slit 2314a and the front opening H21 of the second slit 2315a in the front portion 2311a and the region between the front opening H11 of the first slit 2314a and the left end surface in the front portion 2311 a.
On the other hand, as another form of performing a collector or pocket function on dew, a plurality of horizontal protrusions in a rib shape may be formed on the front surface portion 2311a of the left blade 231 a.
In this case, a plurality of horizontal protrusions are configured to protrude from the front surface portion 2311a of the left blade 231a by a predetermined height and extend in the horizontal direction, and a space formed between the plurality of horizontal protrusions may serve as a collector or pocket of dew.
Fig. 8 to 10 illustrate the left blade 231a and the left discharge port 224a as references, but the detailed structure is equally applicable to the right blade 231b and the right discharge port 224b. A description of the repeated structure of the right vane 231b and the right discharge port 224b will be omitted.

The processor 1190 may control motors 1173 and 1174 corresponding to the third blade 231a2 and the fourth blade 231b2, respectively, so that the third blade 231a2 and the fourth blade 231b2 disposed on the left side surface and the right side surface of the lower end of the air conditioner 1 face the side of the air conditioner 1.
According to an embodiment, the processor 1190 may control each of the corresponding motors 1171, 1172, 1173, 1174 to direct the four blades 231a1, 231b1, 231a2, 231b2 of the air conditioner 1 toward the side of the air conditioner 1, thereby causing the air conditioner 1 to operate in a diffusion mode. The processor 1190 may control the air conditioner 1 such that the air conditioner 1 operates in a diffusion mode in which air is discharged sideways.
For example, when the air conditioner 1 is to be operated in the diffusion mode, the processor 1190 may control the motors 1171, 1172 corresponding to the first blade 231a1 and the second blade 231b1, respectively, so that the first blade 231a1 and the second blade 231b1 respectively disposed on the left side surface and the right side surface of the upper end of the air conditioner 1 face the side of the air conditioner 1. The processor 1190 may control motors 1173 and 1174 corresponding to the third blade 231a2 and the fourth blade 231b2, respectively, so that the third blade 231a2 and the fourth blade 231b2 disposed on the left side surface and the right side surface of the lower end of the air conditioner 1 face the side of the air conditioner 1.
According to an embodiment, the processor 1190 may hold or move the two blades 231a1, 231a2 of the air conditioner 1 to a state hidden in the storage position on the back side of the front panel 14 of the air conditioner 1, so that the air conditioner 1 operates in the right diffusion mode. In addition, the processor 1190 may control each of the corresponding motors 1172, 1174 such that the two blades 231b1, 231b2 of the air conditioner 1 face sideways of the air conditioner 1. The processor 1190 may control the air conditioner 1 such that the air conditioner 1 operates in a right diffusion mode in which air is discharged forward and rightward.
For example, when the air conditioner 1 is to be operated in the right diffusion mode, the processor 1190 may hold or move the first vane 231a1 disposed on the upper left side surface of the air conditioner 1 and the third vane 231a2 disposed on the lower left side surface of the air conditioner 1 to a state hidden in the storage position on the rear surface side of the front surface plate 14 of the air conditioner 1. Further, the processor 1190 may control the motors 1172, 1174 corresponding to the second blade 231a2 and the fourth blade 231b2, respectively, such that the second blade 231a2 disposed on the right side of the upper end of the air conditioner 1 and the fourth blade 231b2 disposed on the right side of the lower end of the air conditioner 1 face the side of the air conditioner 1.
According to an embodiment, the processor 1190 may control each of the corresponding motors 1171, 1173 to direct the two blades 231a1, 231a2 of the air conditioner 1 toward the side of the air conditioner 1 to thereby operate the air conditioner 1 in a left diffusion mode. The processor 1190 may hold or move the two blades 231b1, 231b2 of the air conditioner 1 to a storage position hidden on the back side of the front panel 14 of the air conditioner 1. The processor 1190 may control the air conditioner 1 such that the air conditioner 1 operates in a left diffusion mode in which air is discharged forward and leftward.
For example, when the air conditioner 1 is to be operated in the left diffusion mode, the processor 1190 may control the motors 1171, 1173 respectively corresponding to the first blade 231a1 and the third blade 231a2 such that the first blade 231a1 disposed on the left side surface of the upper end of the air conditioner 1 and the third blade 231a2 disposed on the left side surface of the lower end of the air conditioner 1 face the side of the air conditioner 1. The processor 1190 may hold or move the second vane 231a2 disposed on the upper right side surface of the air conditioner 1 and the fourth vane 231b2 disposed on the lower right side surface of the air conditioner 1 to a storage position hidden on the rear surface side of the front panel 14 of the air conditioner 1.
According to an embodiment, the processor 1190 may control the motors in the motor portion 1170 to move the plurality of blades 231a1, 231b1, 231a2, 231b2 and the front discharge port 141 included in the wind direction control portion 1180.
According to an embodiment, the processor 1190 may control the air conditioner 1 to operate in any one or at least one of a quick mode, a comfort mode, a human body adaptation mode, a sleep mode, a rest mode, a power saving mode, and a natural wind mode.
According to one embodiment, the processor 1190 may operate the air conditioner 1 with natural wind.
For example, when the processor 1190 is to operate the air conditioner 1 in natural wind, the processor 1190 may operate the air conditioner 1 based on a concentrated mode during a first time (e.g., 30 minutes) and operate the air conditioner 1 based on an upper concentrated mode during a second time (e.g., 10 minutes) after the first time. Further, the processor 1190 may operate the air conditioner 1 based on a concentrated mode during a third time (e.g., 10 minutes) after the second time, and operate the air conditioner 1 based on a diffuse mode during a fourth time (e.g., 10 minutes) after the third time.
Further, after the actions of the concentration mode, the upper concentration mode, the concentration mode, and the diffusion mode sequentially performed based on the first time to the fourth time, the processor 1190 may repeatedly perform the procedures including: the air conditioner 1 is based on the concentrated action during the second time (e.g., 10 minutes), the air conditioner 1 is based on the concentrated action during the third time (e.g., 10 minutes), and the air conditioner 1 is based on the diffused action during the fourth time (e.g., 10 minutes). The air conditioner 1 may operate in a natural wind mode by repeatedly performing the above-described operations according to the up-concentration mode, the concentration mode, and the diffusion mode by the processor 1190.
According to one embodiment, the processor 1190 may obtain a set temperature of the air conditioner 1. The processor 1190 may receive a signal including operation information for controlling the operation of the air conditioner 1 from a remote control device (not shown) (e.g., a remote controller) through the communication unit 1110. Alternatively, the processor 1190 may receive a command including operation information for controlling the operation of the air conditioner 1 through the input unit 1120.
According to an embodiment, the operation information may include at least a part of information of an operation mode (a quick mode, a comfort mode, a human body adaptation mode, a sleep mode, a rest mode, a power saving mode, a natural wind mode, an upper concentration mode, a diffusion mode, a left diffusion mode, a right diffusion mode, a breeze mode, etc.), operation time information, and initial set temperature information of the air conditioner 1.
According to an embodiment, the processor 1190 may obtain information of the set temperature of the air conditioner 1 and the operation mode (e.g., power saving mode) of the air conditioner 1 from the operation information. For example, the processor 1190 may operate the air conditioner 1 in a power saving mode for a set time (e.g., 10 hours).
According to an embodiment, the processor 1190 may control the activity of each of the plurality of vanes 231a1, 231b1, 231a2, 231b2 based on the set temperature obtained and a time set for each of a plurality of desired temperatures. The processor 1190 may control the activity of each of the plurality of vanes 231a1, 231b1, 231a2, 231b2 based on at least one of the set temperatures acquired and a time set for each of a plurality of desired temperatures. The time set for each of a plurality of the desired temperatures may be set longer as the desired temperature increases. For example, the following [ table 1] shows a time (e.g., a human body adaptation time) set for each of a plurality of desired temperatures according to an embodiment of the present invention.
[ Table 1]
Desired temperature (. Degree. C.) 18-22 23 24 25 26 27 28
Adaptation time (minutes) 19 23 30 35 40 54 70
Referring to table 1, when the current desired temperature (for example, the temperature at which the air conditioner 1 is currently operated) is 22 ℃, the air conditioner 1 is reset to raise the desired temperature by 1 ℃ and operates when the adaptive time (for example, the time at which the air conditioner 1 is operated at 22 ℃ for 19 minutes) has elapsed. When the adaptation time (for example, when the air conditioner 1 is operated at 23 ℃ for 23 minutes) has elapsed, the air conditioner 1 is reset to raise the desired temperature by 1 ℃ and operates. Similarly, if an adaptive time (for example, a time of 30 minutes at 24 ℃) elapses, the air conditioner 1 resets the desired temperature to 1 ℃ and operates. As described above, the processor 1190 may gradually increase the temperature at which the air conditioner 1 is currently operating based on a preset desired temperature and an adaptation time.
As shown in table 1 above, a corresponding human body adaptation time may be set for each of a plurality of desired temperatures. Such a human body adaptation time refers to a time required for a user's human body to adapt to a desired temperature when the indoor temperature is adjusted to the temperature (i.e., a human body adaptation time).
According to an embodiment, the processor 1190 may control the wind direction control part 1180 based on the acquired set temperature and a time set for each of a plurality of desired temperatures such that the air conditioner 1 operates in at least one of a concentrated mode, an up-concentrated mode, a diffuse mode, a right diffuse mode, and a left diffuse mode. The processor 1190 may control the activity of each of the plurality of blades 231a1, 231b1, 231a2, 231b2 included in the wind direction control part 1180 such that the air conditioner 1 operates in at least one of a concentrated mode, an upper concentrated mode, a diffuse mode, a right diffuse mode, and a left diffuse mode.
According to an embodiment, the processor 1190 may operate the air conditioner in a concentrated mode during a first time (e.g., 30 minutes) based on a desired temperature (e.g., 21 ℃) that is lower than the acquired set temperature (e.g., 23 ℃) by a predetermined first temperature (e.g., 2 ℃). Further, the processor 1190 may operate the air conditioner 1 in the above concentrated mode during a second time (e.g., 30 minutes) after the first time (e.g., 30 minutes) based on the acquired set temperature (e.g., 23 ℃). The first time and the second time may be the same or different from each other.
According to an embodiment, the processor 1190 may operate the air conditioner 1 in the upper concentrated mode after the second time period (e.g., 30 minutes) based on a time set for each of a plurality of the desired temperatures in any one of the concentrated mode and the upper concentrated mode.
According to an embodiment, the processor 1190 may operate the air conditioner 1 in any one of the concentration mode and the upper concentration mode based on the above [ table 1] after operating the air conditioner 1 in the upper concentration mode during the second time (e.g., 30 minutes).
According to an embodiment, the processor 1190 may control the first and second blades 231a1 and 231b1 disposed at the upper end of the air conditioner 1 and the third and fourth blades 231a2 and 231b2 disposed at the lower end of the air conditioner 1 to face the front of the air conditioner 1. Further, the processor 1190 may operate the air conditioner based on a concentration pattern for discharging air to correspond to the adaptation time of [ table 1] described above.
For example, the processor 1190 may control the motors 1171 and 1172 corresponding to the first blade 231a1 and the second blade 231b1, respectively, so that the first blade 231a1 and the second blade 231b1 disposed on the left side surface and the right side surface of the upper end of the air conditioner 1, respectively, face the front of the air conditioner 1. The processor 1190 may control motors 1173 and 1174 corresponding to the third blade 231a2 and the fourth blade 231b2, respectively, so that the third blade 231a2 and the fourth blade 231b2 disposed on the left side surface and the right side surface of the lower end of the air conditioner 1 face the front of the air conditioner 1.
The processor 1190 may control motors 1171 and 1172 corresponding to the first blade 231a1 and the second blade 231b1, respectively, so that the first blade 231a1 and the second blade 231b1 disposed on the left side surface and the right side surface of the upper end of the air conditioner 1 are directed to the front of the air conditioner 1. The processor 1190 may control motors 1173 and 1174 corresponding to the third blade 231a2 and the fourth blade 231b2, respectively, so that the third blade 231a2 and the fourth blade 231b2 disposed on the left side surface and the right side surface of the lower end of the air conditioner 1 face the side of the air conditioner 1.
According to an embodiment, the processor 1190 operates the air conditioner 1 in the up-concentrated mode during the second time (e.g., 30 minutes). Thereafter, the processor 1190 may operate the air conditioner 1 in any one of the concentrated mode and the upper concentrated mode such that the operation temperature of the air conditioner 1 becomes the first desired temperature (e.g., 28 ℃) based on [ table 1] described above.
According to an embodiment, when the operation temperature of the air conditioner 1 becomes the first desired temperature (e.g., 28 ℃), the processor 1190 may operate the air conditioner 1 in any one of the concentration mode and the upper concentration mode such that the operation temperature of the air conditioner 1 becomes the second desired temperature (e.g., 26 ℃).
According to an embodiment, when the operation temperature of the air conditioner 1 becomes the second desired temperature (e.g., 26 ℃), the processor 1190 may operate the air conditioner 1 in any one of the concentration mode and the upper concentration mode such that the operation temperature of the air conditioner 1 becomes the first desired temperature again (e.g., 28 ℃). The first desired temperature may be higher than the second desired temperature.
According to an embodiment, the processor 1190 may operate the air conditioner 1 in any one of the concentrated mode and the upper concentrated mode based on the time set for each of the plurality of desired temperatures of [ table 1] above such that the operation temperature of the air conditioner 1 alternately corresponds to the first desired temperature (e.g., 28 ℃) and the second desired temperature (e.g., 26 ℃) within a preset operation time (e.g., 10 hours).
For example, the processor 1190 may operate the air conditioner 1 in any one of the concentrated mode and the upper concentrated mode based on the time set for each of the plurality of desired temperatures of [ table 1] above such that the operation temperature of the air conditioner 1 corresponds to the first desired temperature (e.g., 28 ℃) within a preset operation time (e.g., 10 hours). Thereafter, when the operation temperature of the air conditioner 1 corresponds to the first desired temperature (e.g., 28 ℃), the processor 1190 may operate the air conditioner 1 in any one of the concentration mode and the upper concentration mode based on the time set for each of the plurality of desired temperatures of [ table 1] so that the operation temperature of the air conditioner 1 corresponds to the second desired temperature (e.g., 26 ℃). Further, when the operation temperature of the air conditioner 1 corresponds to the second desired temperature (e.g., 26 ℃), the processor 1190 may operate the air conditioner 1 in any one of the concentrated mode and the upper concentrated mode based on the time set for each of the plurality of desired temperatures of [ table 1] above, such that the operation temperature of the air conditioner 1 corresponds to the first desired temperature (e.g., 28 ℃) again.
As described above, the processor 1190 may operate the air conditioner 1 in any one of the concentrated mode and the upper concentrated mode such that the operation temperature of the air conditioner 1 alternately corresponds to the first desired temperature (e.g., 28 ℃) and the second desired temperature (e.g., 26 ℃) within a preset operation time (e.g., 10 hours).
Fig. 12 is a flowchart showing a process for controlling the operation of an air conditioner according to an embodiment of the present invention.
Hereinafter, a process for controlling the operation of an air conditioner according to an embodiment of the present invention will be described in detail with reference to fig. 12.
According to an embodiment, the air conditioner 1 (e.g., the processor 1190) may recognize whether motion information is input (S1210). The air conditioner 1 (for example, the processor 1190) may receive a signal including operation information for controlling an operation of the air conditioner 1 from a remote control device (not shown) (for example, a remote controller) through the communication unit 1110. Alternatively, the air conditioner 1 (for example, the processor 1190) may receive a command including operation information for controlling the operation of the air conditioner 1 through the input unit 1120.
For example, the operation information may include at least part of information of an operation mode (a quick mode, a comfort mode, a human body adaptation mode, a sleep mode, a rest mode, a power saving mode, a natural wind mode, an upper concentration mode, a diffusion mode, a left diffusion mode, a right diffusion mode, a breeze mode, etc.), operation time information, and operation temperature information of the air conditioner 1.
According to an embodiment, the air conditioner 1 (for example, the processor 1190) may identify operation information of the air conditioner included in the operation information (S1212). The air conditioner 1 (e.g., the processor 1190) may analyze the operation information to identify which mode, how long, or at how much celsius the air conditioner 1 is to operate.
According to an embodiment, the air conditioner 1 (e.g., the processor 1190) may control the operation of each of the four blades based on the identified operation information (S1214). The air conditioner 1 (for example, the processor 1190) may control the operation of each (or a part of the same) of the plurality of blades 141, 231a1, 231b1, 231a2, 231b2 included in the wind direction control unit 1180 based on the identified operation information. The air conditioner 1 (for example, the processor 1190) may control the direction of each of the plurality of blades 141, 231a1, 231b1, 231a2, 231b2 included in the wind direction control unit 1180 by controlling the corresponding motor so as to correspond to an operation mode in which the air conditioner 1 operates.
According to an embodiment, the air conditioner 1 (e.g., the processor 1190) may control the directions in which two of the four blades 231a1, 231b1, 231a2, 231b2 are oriented differently from the directions in which the other two blades are oriented based on the operation of the air conditioner 1.
According to an embodiment, the air conditioner 1 (for example, the processor 1190) may drive the motors 1171, 1172, 1173, 1174 corresponding to each of the four blades based on the operation of the air conditioner 1 such that the direction in which at least one blade of the four blades 231a1, 231b1, 231a2, 231b2 is oriented is different from the direction in which the remaining blades are oriented.
According to an embodiment, the air conditioner 1 (for example, the processor 1190) may control the movement (or direction) of the front discharge port 141 included in the wind direction control part 1180 based on the motion of each of the four blades.
According to an embodiment, the air conditioner 1 (for example, the processor 1190) may identify a situation of an indoor space where the air conditioner 1 is located through at least one sensor 1151, 1152, 1153 of the sensor part 1150, and determine an action of each of the plurality of blades 141, 231a1, 231b1, 231a2, 231b2 based on the identified situation.
According to an embodiment, the air conditioner 1 (for example, the processor 1190) may acquire information of the position and movement of a user in an indoor space through at least one of the sensors 1151, 1152, 1153 configured on the external appearance of the air conditioner 1, and identify the situation based on the acquired information.
For example, the air conditioner 1 (e.g., the processor 1190) may identify whether an indoor person is standing, sitting, or lying based on information of the position and movement of a user in an indoor space acquired through at least one of the sensors 1151, 1152, 1153. In addition, the air conditioner 1 (for example, the processor 1190) may analyze the image acquired through the visual sensor 1153 and extract depth information of an indoor person, thereby predicting a distance between the indoor person and the air conditioner 1. The air conditioner 1 (e.g., the processor 1190) can recognize whether a person in a room is in a living room or in a kitchen, sitting on a sofa, or sitting in front of a desk through the image.
According to an embodiment, the air conditioner 1 (for example, the processor 1190) may acquire operation information of the air conditioner 1 received through the communication section 1110, and determine the operation of the air conditioner 1 based on the acquired information. The air conditioner 1 (for example, the processor 1190) may receive a control signal for controlling the operation of the air conditioner 1 through a remote control device (not shown) (for example, a remote controller) paired with the air conditioner 1, and determine an operation mode of the air conditioner 1 based on the received control signal.
According to an embodiment, the air conditioner 1 (e.g., the processor 1190) may cause the air conditioner 1 to operate in at least one of a concentrated, an up-concentrated, a diffuse, a right diffuse, and a left diffuse mode based on the operation of each of a plurality of the blades. The air conditioner 1 (e.g., the processor 1190) may control the operation of each of the plurality of blades such that the air conditioner 1 operates in at least one of a concentrated, a concentrated up, a spread, a right spread, and a left spread mode.
According to an embodiment, the air conditioner 1 (for example, the processor 1190) may hold or move the four blades 231a1, 231b1, 231a2, 231b2 of the air conditioner 1 to a state hidden in the storage position on the back side of the front panel 14 of the air conditioner 1, so that the air conditioner 1 operates in the concentrated mode. To this end, the air conditioner 1 (e.g., the processor 1190) may control each of the corresponding motors 1171, 1172, 1173, 1174. The air conditioner 1 (for example, the processor 1190) may control the air conditioner 1 such that the air conditioner 1 operates in a concentrated mode in which air is discharged in a concentrated manner in the forward direction.
According to an embodiment, the air conditioner 1 (for example, the processor 1190) may hold or move the two blades 231a1, 231b1 of the air conditioner 1 to a storage position hidden on the back side of the front panel 14 of the air conditioner 1, so that the air conditioner 1 operates in the above concentrated mode. To this end, the air conditioner 1 (e.g., the processor 1190) may control each of the corresponding motors 1171, 1172. Further, the air conditioner 1 (e.g., the processor 1190) may control each of the corresponding motors 1173, 1174 such that the other two blades 231a2, 231b2 face sideways of the air conditioner 1. The air conditioner 1 (for example, the processor 1190) may control the air conditioner 1 such that the air conditioner 1 operates in a top-concentrated mode in which air is discharged forward and sideways.
According to an embodiment, the air conditioner 1 (e.g., the processor 1190) may control each of the corresponding motors 1171, 1172, 1173, 1174 such that the four blades 231a1, 231b1, 231a2, 231b2 of the air conditioner 1 face sideways of the air conditioner 1, thereby operating the air conditioner 1 in a diffusion mode. The air conditioner 1 (for example, the processor 1190) may control the air conditioner 1 such that the air conditioner 1 operates in a diffusion mode in which air is discharged sideways.
According to an embodiment, the air conditioner 1 (for example, the processor 1190) may maintain the two blades 231a1, 231a2 of the air conditioner 1 in a state hidden in the storage position on the back side of the front panel 14 or in a hidden state, so that the air conditioner 1 operates in the right diffusion mode. In addition, the air conditioner 1 (e.g., the processor 1190) may control each of the corresponding motors 1172, 1174 such that the two blades 231b1, 231b2 of the air conditioner 1 face sideways of the air conditioner 1. The air conditioner 1 (for example, the processor 1190) may control the air conditioner 1 such that the air conditioner 1 operates in a right diffusion mode in which air is discharged to the front and right.
According to an embodiment, the air conditioner 1 (e.g., the processor 1190) may control each of the corresponding motors 1171, 1173 such that the two blades 231a1, 231a2 of the air conditioner 1 face sideways of the air conditioner 1, thereby operating the air conditioner 1 in a left diffusion mode. The air conditioner 1 (for example, the processor 1190) may hold the two blades 231b1 and 231b2 of the air conditioner 1 in a state hidden in the storage position on the back side of the front panel 14 or in a hidden state. The air conditioner 1 (for example, the processor 1190) may control the air conditioner 1 such that the air conditioner 1 operates in a left diffusion mode in which air is discharged forward and leftward.
According to an embodiment, the air conditioner 1 (for example, the processor 1190) may control the motors in the motor unit 1170 such that the plurality of blades 231a1, 231b1, 231a2, 231b2 and the front discharge port 141 included in the wind direction control unit 1180 each operate in different directions from each other.
According to an embodiment, the air conditioner 1 (e.g., the processor 1190) may control the air conditioner 1 to operate in any one or at least one of a quick mode, a comfort mode, a human-body-adaptive mode, a sleep mode, a rest mode, a power saving mode, and a natural wind mode.
According to an embodiment, the air conditioner 1 (e.g., the processor 1190) may discharge air based on the motion of each of the blades (S1216). The air conditioner 1 (for example, the processor 1190) may discharge air to the outside based on the control of at least one blade in the above-described process (S1214). The air conditioner 1 (for example, the processor 1190) may control at least one of the front air supply fan 311 and the side air supply fans 321a, 321b, 321c according to the corresponding RPM, and adjust the direction of air supplied by the fan controlled by the RPM based on the action of at least one blade. The air conditioner 1 (for example, the processor 1190) can selectively discharge air by controlling the front discharge port 141 included in the wind direction control unit 1180 based on the operation of the air conditioner 1.
Fig. 13a is an exemplary diagram of an air conditioner according to an embodiment of the present invention operating in a centralized mode. Fig. 13b is an exemplary diagram of the above concentrated mode operation of the air conditioner according to an embodiment of the present invention. Fig. 13c is a diagram illustrating an operation of the air conditioner in a diffusion mode according to an embodiment of the present invention. Fig. 13d is an exemplary diagram of an air conditioner according to an embodiment of the present invention operating in a right diffusion mode. Fig. 13e is an exemplary diagram of an air conditioner operating in a left diffusion mode according to an embodiment of the present invention.
Referring to fig. 13a, the air conditioner 1 according to an embodiment of the present invention may operate in a concentrated mode by maintaining the four blades 231a1, 231b1, 231a2, 231b2 of the air conditioner 1 in a state or a hidden state hidden in the storage position on the back side of the front panel 14 of the air conditioner 1 under the control of the processor 1190.
For example, when the air conditioner 1 is to be operated in the concentrated mode under the control of the processor 1190, the first and second blades 231a1 and 231b1 disposed on the left and right sides of the upper end of the air conditioner 1 may be kept in a state or a hidden state hidden in the storage position on the back side of the front panel 14. The air conditioner 1 may maintain the third blade 231a2 and the fourth blade 231b2 disposed on the left side surface and the right side surface of the lower end of the air conditioner 1 in a state of being hidden in the storage position on the back side of the front panel 14 or in a hidden state under the control of the processor 1190.
For example, when the air conditioner 1 is operated in the concentrated mode, the four blades 231a1, 231b1, 231a2, 231b2 may be kept disposed inside the air conditioner 1 under the control of the processor 1190.
Referring to fig. 13b, the air conditioner 1 according to an embodiment of the present invention may operate in the above concentrated mode by maintaining the two blades 231a1, 231b1 of the air conditioner 1 in a state hidden in the storage position on the rear surface side of the front panel 14 or in a hidden state under the control of the processor 1190. Further, the air conditioner 1 may adjust each of the other two blades 231a2, 231b2 to be directed to the side (Ri direction or Le direction) of the air conditioner 1 under the control of the processor 1190, thereby operating in the above concentrated mode.
For example, when the air conditioner 1 is to operate in the above concentrated mode under the control of the processor 1190, the first and second blades 231a1 and 231b1 disposed on the left and right sides of the upper end of the air conditioner 1 may be held in a state or a hidden state in which they are hidden in the storage position on the rear surface side of the front panel 14. The air conditioner 1 may adjust the third blade 231a2 and the fourth blade 231b2 disposed on the left side surface and the right side surface of the lower end of the air conditioner 1 to be directed to the side (Ri direction or Le direction) of the air conditioner 1 under the control of the processor 1190.
For example, when the air conditioner 1 is operated in the above concentrated mode, the first blade 231a1 and the second blade 231b1 may be disposed inside the air conditioner 1, and the third blade 231a2 and the fourth blade 231b2 may be extended outside the air conditioner 1 under the control of the processor 1190.
Referring to fig. 13c, the air conditioner 1 according to an embodiment of the present invention may be operated in a diffusion mode by adjusting the four blades 231a1, 231b1, 231a2, 231b2 of the air conditioner 1 to be directed to the sides (Ri direction and Le direction) of the air conditioner 1 under the control of the processor 1190.
For example, when the air conditioner 1 is to be operated in the diffusion mode under the control of the processor 1190, the first and second blades 231a1 and 231b1 disposed on the left and right sides of the upper end of the air conditioner 1 may be adjusted to face the sides (Ri and Le directions) of the air conditioner 1.

Referring to fig. 20, in the air conditioner 1 (for example, the processor 1190), the two blades 231a1 and 231b1 can be kept hidden in the storage position on the back side of the front panel 14 of the air conditioner 1. In the air conditioner 1 (for example, the processor 1190), the remaining two blades 231a2 and 231b2 may be protruded to the side of the air conditioner 1 at the set temperature Ts during the second time period 2012 (for example, 30 minutes) o (e.g., 23 ℃) the air conditioner 1 is operated.
According to one embodiment, the air conditioner 1 (e.g., the processor 1190) may identify whether the set temperature is above a first desired temperature (e.g., 28 ℃) (S1920). The air conditioner 1 (e.g., the processor 1190) may recognize whether the set temperature Ts (e.g., 23 ℃) of the air conditioner 1 is above a first desired temperature (e.g., 28 ℃) during operation of the air conditioner 1 based on the above [ table 1 ].
According to an embodiment, the air conditioner 1 (e.g., the processor 1190) may control the four blades 231a1, 231b1, 231a2, 231b2 to correspond to the concentrated mode (S1922). If the air conditioner 1 recognizes that the set temperature Ts (e.g., 23 ℃) of the air conditioner 1 is not above the first desired temperature (e.g., 28 ℃) during operation of the air conditioner 1 based on the above [ table 1], the air conditioner 1 (e.g., the processor 1190) may operate the air conditioner 1 in any one of a concentrated mode and a concentrated up mode based on a time set for each of a plurality of desired temperatures of the above [ table 1 ].
For example, the air conditioner 1 (e.g., the processor 1190) may operate the air conditioner 1 in a concentrated mode for a predetermined time (e.g., a time for which the blades remain in the current state) (e.g., 10 minutes) based on a time set for each of a plurality of desired temperatures of [ table 1] described above. Thereafter, the air conditioner 1 (e.g., the processor 1190) increases the set temperature Ts (e.g., the operation temperature) (e.g., 23 ℃) by a predetermined temperature (e.g., 1 ℃) (e.g., 24 ℃).
According to an embodiment, the air conditioner 1 (e.g., the processor 1190) may identify whether the time during which the air conditioner 1 is operated in at least one of the concentrated mode and the upper concentrated mode is above an adaptation time corresponding to a desired temperature (S1924). The air conditioner 1 (for example, the processor 1190) may recognize whether or not the time during which the air conditioner 1 is operated in the concentrated mode is equal to or longer than an adaptive time corresponding to a desired temperature.
For example, if the air conditioner 1 is operated in the concentrated mode for less than the adaptation time corresponding to the desired temperature, the air conditioner 1 (e.g., the processor 1190) may operate the air conditioner 1 in the concentrated mode for more than a predetermined time (e.g., the time the blades remain in the current state) (e.g., 10 minutes). Thereafter, the air conditioner 1 (e.g., the processor 1190) may raise the set temperature Ts (e.g., the operating temperature) (e.g., 24 ℃) by a predetermined temperature (e.g., 1 ℃) (e.g., 25 ℃).
Thereafter, the air conditioner 1 (for example, the processor 1190) may recognize whether or not the time for which the air conditioner 1 is operated in the above-concentration mode is equal to or longer than the adaptive time corresponding to the desired temperature.
For example, the air conditioner 1 (for example, the processor 1190) may continuously increase the set temperature Ts (for example, the operation temperature) in units of a predetermined temperature (for example, 1 ℃) until the time when the air conditioner 1 is operated in the concentrated mode and the upper concentrated mode reaches the adaptation time corresponding to the desired temperature or more. The air conditioner 1 (e.g., the processor 1190) may operate the air conditioner 1 in a concentrated mode or an upper concentrated mode, and repeatedly adjust the four blades 231a1, 231b1, 231a2, 231b2 to correspond to any one of the concentrated mode and the upper concentrated mode until the time of operation in the concentrated mode and the upper concentrated mode reaches an adaptation time corresponding to a desired temperature or more. For example, the air conditioner 1 (e.g., the processor 1190) may continuously increase the set temperature Ts (e.g., the operating temperature) in units of a predetermined temperature (e.g., 1 ℃) until a first desired temperature (e.g., 28 ℃) is reached.
Referring to fig. 20, the air conditioner 1 (for example, the processor 1190) may repeatedly operate the air conditioner 1 in a concentrated mode or an upper concentrated mode to set the temperature Ts of the air conditioner 1 o Continuously to a first desired temperature (e.g., 28 ℃) via 2013, 2014, 2015, 2016, 2017.
According to an embodiment, in the air conditioner 1 (e.g., the processor 1190), the air conditioner 1 (e.g., the processor 1190) may recognize whether the set temperature is below a second desired temperature (e.g., 26 ℃) (S1926). If it is recognized that the set temperature Ts of the air conditioner 1 is above a first desired temperature (e.g., 28 ℃) during operation of the air conditioner 1 based on the above [ table 1], the air conditioner 1 (e.g., the processor 1190) may recognize whether the set temperature is below a second desired temperature (e.g., 26 ℃).
According to an embodiment, the air conditioner 1 (for example, the processor 1190) may identify whether the time during which the air conditioner 1 operates in at least one of the concentrated mode and the upper concentrated mode is above an adaptation time corresponding to a desired temperature (S1928). If the air conditioner 1 recognizes that the set temperature Ts of the air conditioner 1 is not above the second desired temperature (e.g., 26 ℃) during operation of the air conditioner 1 based on the above [ table 1], the air conditioner 1 (e.g., the processor 1190) may operate the air conditioner 1 in any one of the concentrated mode and the upper concentrated mode based on the time set for each of the plurality of desired temperatures of the above [ table 1 ].
For example, the air conditioner 1 (e.g., the processor 1190) may operate the air conditioner 1 in a concentrated mode based on a time set for each of a plurality of desired temperatures of [ table 1] described above for a predetermined time (e.g., a time when the blade is kept in a current state) (e.g., 10 minutes). Thereafter, the air conditioner 1 (for example, the processor 1190) lowers the set temperature Ts (for example, the operation temperature) by a predetermined temperature (for example, 1 ℃).
According to an embodiment, the air conditioner 1 (e.g., the processor 1190) may identify whether the time during which the air conditioner 1 operates in at least one of the concentrated mode and the upper concentrated mode is above an adaptation time corresponding to a desired temperature (S1930). The air conditioner 1 (for example, the processor 1190) may recognize whether or not the time during which the air conditioner 1 is operated in the concentrated mode is equal to or longer than an adaptive time corresponding to a desired temperature.
For example, in the air conditioner 1 (for example, the processor 1190), if the time during which the air conditioner 1 is operated in the concentrated mode is not equal to or longer than the adaptive time corresponding to the desired temperature, the air conditioner 1 may be operated in the concentrated mode for a predetermined time (for example, a time during which the blades are kept in the current state) (for example, 10 minutes). Thereafter, the air conditioner 1 (for example, the processor 1190) lowers the set temperature Ts (for example, the operation temperature) by a predetermined temperature (for example, 1 ℃).
Thereafter, the air conditioner 1 (for example, the processor 1190) may recognize whether or not the time for which the air conditioner 1 is operated in the above-concentration mode is equal to or longer than the adaptive time corresponding to the desired temperature.
For example, the air conditioner 1 (for example, the processor 1190) may continuously decrease the set temperature Ts (for example, the operation temperature) in units of a predetermined temperature (for example, 1 ℃) until the time when the air conditioner 1 is operated in the concentrated mode and the upper concentrated mode reaches the adaptation time corresponding to the desired temperature or more. The air conditioner 1 (e.g., the processor 1190) may operate the air conditioner 1 in a concentrated mode or an upper concentrated mode, and repeatedly adjust the four blades 231a1, 231b1, 231a2, 231b2 to correspond to any one of the concentrated mode and the upper concentrated mode until the time of operation in the concentrated mode and the upper concentrated mode reaches an adaptation time corresponding to a desired temperature or more. For example, the air conditioner 1 (e.g., the processor 1190) may continuously decrease the set temperature Ts (e.g., the operating temperature) in units of a predetermined temperature (e.g., 1 ℃) until a second desired temperature (e.g., 26 ℃) is reached.
Referring to fig. 20, the air conditioner 1 (for example, the processor 1190) may repeatedly operate the air conditioner 1 in a concentrated mode or an upper concentrated mode to set the temperature Ts of the air conditioner 1 o Continuously via 2018, 2019 to a second desired temperature (e.g., 26 ℃).
Fig. 21a is a graph showing the result of accumulated power in the air conditioner of the related art. Fig. 21b is a graph showing the result of accumulated power in the air conditioner according to an embodiment of the present invention.
Referring to fig. 21a and 21b, the related art air conditioner spends a predetermined time (about 48 minutes 01 seconds) before reaching a set temperature (e.g., 26 c), and then the indoor temperature 2110 gradually decreases as the air conditioner operates at the preset temperature. Further, the accumulated power 2120 consumed by the air conditioner of the related art for a predetermined time (e.g., 4 hours) is 5675Wh. In addition, the instantaneous power consumption 2130 of the prior art air conditioner increases sharply before reaching the set temperature (e.g., 26 ℃) and then decreases slightly.
In contrast, the air conditioner 1 according to the embodiment of the present invention takes a predetermined time (about 24 minutes and 28 seconds) before reaching the set temperature (e.g., 26 ℃), and thereafter, as the air conditioner is operated at the preset temperature, the indoor temperature 2140 is maintained within the prescribed range. Further, the cumulative power 2150 consumed by the air conditioner 1 for a predetermined time (for example, 4 hours) is 3111Wh. In addition, the instantaneous power consumption 2160 of the air conditioner 1 increases sharply before reaching a set temperature (e.g., 26 ℃), and then decreases sharply. In addition, the instantaneous power consumption 2160 remains low.
As described above, when comparing the set arrival times in the prior art air conditioner and the air conditioner of the present invention, the air conditioner of the present invention is faster than the prior art air conditioner for about 24 minutes, and the cumulative power consumption has an efficiency of about 45.2%.
Fig. 22a is a result of thermal comfort and airflow discomfort in the prior art air conditioner. Fig. 22b is a result of thermal comfort and airflow discomfort in an air conditioner according to an embodiment of the invention.
Referring to fig. 22a and 22b, based on the experiment of fig. 21a, in the case of the related art air conditioner, the thermal comfort 2210 is about 66.2%, and the airflow discomfort 2220 is about 38.8%. Further, based on the experiment of fig. 21b, in the case of the air conditioner 1 of an embodiment of the present invention, the thermal comfort 2230 was about 94.7%, and the air flow discomfort 2240 was about 24.9%.
Referring to fig. 22b, the processor 1190 operates the air conditioner 1 in a concentrated mode based on a set temperature (e.g., 24 ℃) during a first time 2241 (e.g., 30 minutes) and operates the air conditioner 1 in a concentrated mode based on a set temperature (e.g., 26 ℃) or higher during a second time 2242 (e.g., 30 minutes). Thereafter, the processor 1190 operates the air conditioner 1 in a concentrated mode based on a set temperature (e.g., 27 ℃) during a third time 2243 (e.g., 54 minutes) and operates the air conditioner 1 in a concentrated mode based on a set temperature (e.g., 28 ℃) or higher during a fourth time 2244 (e.g., 70 minutes). Thereafter, the processor 1190 operates the air conditioner 1 in a concentrated mode based on a set temperature (e.g., 27 ℃) during a fifth time 2245 (e.g., 54 minutes). It can be seen that by operating the air conditioner 1 based on this sequence, the air conditioner 1 of the present invention has a thermal comfort 2230 of about 94.7% and an airflow discomfort 2240 of about 24.9% as compared to the air conditioner of the related art. For example, there may be a section 2221 where comfort is reduced due to operation at a particular temperature (e.g., 28 ℃).
