Description

Stations and cleaning devices

The present disclosure relates to a station for a robot vacuum cleaner including a mop, and a cleaning device including the same.

Typically, a robot vacuum cleaner is a device that automatically cleans a space by moving around it and sucking up dust and other debris accumulated on the floor without user intervention. A robot vacuum cleaner moves around the cleaning area and cleans it.

The robot vacuum cleaner uses a distance sensor to determine the distance to obstacles such as furniture, office supplies, and walls installed in the cleaning area, and selectively drives the left and right wheel motors of the robot vacuum cleaner to change direction on its own and clean the cleaning area.

Recently, robot vacuums have emerged not only to suck up dust and other foreign substances from the floor, but also to wipe them away. Robot vacuums can also perform wet cleaning using a mop.

One aspect of the present disclosure provides a station and a cleaner capable of reducing contamination of a dust suction inlet of a station for emptying a dust bin of a robot cleaner.

Fig. 15 illustrates a control block diagram of a robot vacuum cleaner according to one embodiment.

Referring to FIG. 15, a robot cleaner (10) according to one embodiment may include an obstacle detection sensor (170), a humidity sensor (171), a battery (150), a user interface (181), a position sensor (183), a driving unit (120), a brush motor (133), a suction motor (142), a driving unit (163), a communication unit (182), and/or a control unit (190).

The obstacle detection sensor (170) detects obstacles that impede the movement of the robot cleaner (10). An obstacle may refer to any object protruding from the floor of the cleaning area and impeding the movement of the robot cleaner (10). For example, not only tables, sofas, etc. located in the cleaning area, but also walls dividing the space may be considered obstacles, and objects that the robot cleaner (10) can climb up and down, such as thresholds or round bars, may also be considered obstacles.

Specifically, the obstacle detection sensor (170) can detect obstacles in a non-contact manner using electromagnetic waves such as infrared rays, visible light, or ultrasonic waves. For example, the obstacle detection sensor (170) can detect infrared rays reflected from an obstacle after irradiating infrared rays, and output the intensity of the detected infrared rays or the time interval (Time Of Flight: TOF) between irradiating infrared rays and detecting the reflected infrared rays to the control unit (190).

The control unit (190) can calculate the presence or absence of an obstacle or the distance between the obstacle and the robot cleaner (10) based on the output value of the obstacle detection sensor (170).

As another example, an obstacle detection sensor (170) may include a transmitter that irradiates electromagnetic waves and a receiver that receives electromagnetic waves reflected from an obstacle.

The transmitter is installed at the front of the main body (110) of the robot cleaner (10) and can transmit electromagnetic waves toward the front of the main body (110). In addition, depending on the embodiment, the transmitter may include an LED that generates electromagnetic waves and a wide-angle lens that refracts the transmitted electromagnetic waves to spread the electromagnetic waves in all directions.

As another example, the obstacle detection sensor (170) may include a camera that acquires images of the vicinity (e.g., front, rear, and/or side) of the robot cleaner (10).

The control unit (190) can calculate the presence or absence of an obstacle or the distance between the obstacle and the robot cleaner (10) based on the image acquired by the obstacle detection sensor (170).

The humidity sensor (171) may include at least one sensor for measuring the humidity (or moisture content) of the mop (160).

In one embodiment, the humidity sensor (171) can measure changes in moisture in the air. The humidity sensor (171) is provided around the mop (160) to measure the humidity (or moisture content) of the mop (160). In this case, the output humidity of the humidity sensor (171) can be proportional to the moisture content of the mop (160).

The control unit (190) can determine the humidity (or moisture content) of the mop (160) based on the humidity measured from the humidity sensor (171).

In one embodiment, the humidity sensor (171) can irradiate the mop (160) with light such as infrared or visible light or electromagnetic waves such as ultrasonic waves and then measure the intensity of the electromagnetic waves reflected from the mop (160) and/or the time interval from the irradiation of the electromagnetic waves until the reflected electromagnetic waves are detected.

For example, the humidity sensor (171) may include a light emitting portion that irradiates light to the mop (160) and a light receiving portion that receives light reflected from the mop (160).

The control unit (190) can determine the humidity (or moisture content) of the mop (160) based on the output value of the humidity sensor (171).

The control unit (190) can perform various operations depending on the humidity (or moisture content) of the mop (160). For example, the control unit (190) can control the driving unit (120) to return the robot cleaner (10) to the station (20) based on the humidity of the mop (160) being measured to be higher than a predetermined maximum humidity. As another example, the control unit (190) can control the driving unit (120) to return the robot cleaner (10) to the station (20) based on the humidity of the mop (160) being measured to be lower than a predetermined minimum humidity.

The battery (150) can supply power to various electrical components of the robot cleaner (10). The battery (150) can be charged while the robot cleaner (10) is placed on the station (20).

The robot vacuum cleaner (10) may include a battery sensor that detects the charge level of the battery (150).

The control unit (190) can control the driving unit (120) to cause the robot cleaner (10) to return to the station (20) when the charge level of the battery (150) falls below a predetermined charge level.

The control unit (190) can determine that the robot cleaner (10) is located at the first position at the station (20) based on the fact that the vacuum cleaner charging terminal (151) of the robot cleaner (10) is electrically connected to the station charging terminal (218) of the station (20).

The user interface (181) may include an output interface and an input interface.

At least one output interface can transmit various information related to the operation of the robot cleaner (10) to the user by generating sensory information.

For example, at least one output interface may transmit information related to the settings of the robot cleaner (10) and the operating time of the robot cleaner (10) to the user. Information related to the operation of the robot cleaner (10) may be output via a display, an indicator, and/or a voice. The at least one output interface may include, for example, a liquid crystal display (LCD) panel, an indicator, a light emitting diode (LED) panel, a speaker, etc.

If the display includes a touch screen display, the touch screen display may be an example of both an output interface and an input interface.

In one embodiment, at least one output interface may output sensory information (e.g., visual information, auditory information, etc.) related to the control of the robot cleaner (10).

At least one input interface can convert sensory information received from a user into an electrical signal.

At least one input interface may include a power button for turning on the robot vacuum cleaner (10).

Each button may include a visual indicator (e.g., text, an icon, etc.) that indicates its function.

At least one input interface may include, for example, a tact switch, a push switch, a slide switch, a toggle switch, a micro switch, a touch switch, a touch pad, a touch screen, a jog dial, and/or a microphone.

In the present disclosure, 'button' may be replaced with a UI element (User Interface Element), a tact switch, a push switch, a slide switch, a toggle switch, a micro switch, a touch switch, a touch pad, a touch screen, a jog dial, and/or a microphone.

The robot cleaner (10) can process user input received through the user interface (181) and output information related to the robot cleaner (10) through the user interface (181).

In one embodiment, the user interface (181) may include an input interface for receiving a mop wash command and/or a mop steam command.

If the user determines that washing or sterilizing the mop (160) of the robot cleaner (10) is necessary, the user can input a mop washing command and/or a mop steam command through the input interface.

The robot cleaner (10) can return to the station (20) when a mop cleaning command and/or a mop steam command is input through the input interface.

When a mop cleaning command and/or a mop steam command is input through the input interface, the robot cleaner (10) can transmit a mop cleaning request signal and/or a mop steam request signal to the station (20).

Accordingly, when the robot cleaner (10) returns to the station (20) and docks at the station (20), the station (20) can perform a washing process and/or a steam process.

The position sensor (183) can detect that the robot cleaner (10) is located at a second position in the station (20). When the robot cleaner (10) is located at the second position in the station (20), the position sensor (183) of the robot cleaner (10) can detect the magnet (283) of the station (20). For example, the position sensor (183) may include a Hall sensor, and the station (20) may be provided with a magnet (283) that can be detected by the Hall sensor. Alternatively, the position sensor may be provided at the station (20), and the robot cleaner (10) may be provided with a magnet.

The control unit (190) can determine that the robot cleaner (10) is at the second position based on the position sensor (183) detecting the magnet (283). Alternatively, if the station (20) is provided with a position sensor and the robot cleaner (10) is provided with a magnet, the control unit (290, see FIG. 16) of the station (20) can determine that the robot cleaner (10) is at the second position based on the position sensor detecting the magnet.

The driving unit (120) may include driving wheels (121, 122) provided on the main body (110) and a wheel motor that provides power to the driving wheels (121, 122).

The driving wheels (121, 122) can move the main body (110) by rotation. The main body (110) can move forward, backward, or rotate by rotation of the driving wheels (122). For example, when both driving wheels (121, 122) rotate forward, the main body (110) can move in a straight line forward, and when both driving wheels (121, 122) rotate backward, the main body (110) can move in a straight line backward.

In addition, when the left and right driving wheels (121) rotate in the same direction but at different speeds, the main body (110) curves to the right or left. When the left and right driving wheels (121) rotate in different directions, the main body (110) can rotate to the left or right in place.

The wheel motor generates rotational force to rotate the driving wheels (121, 122). A DC motor or a BLDC motor may be employed as the wheel motor, but the embodiment of the robot cleaner (10) does not place any restrictions on the type of wheel motor. This applies not only to the wheel motor but also to other motors included in the robot cleaner (10).

The wheel motor may include a left wheel motor that rotates the left driving wheel and a right wheel motor that rotates the right driving wheel.

Each of the left and right wheel motors can operate independently according to a control signal from the control unit (190), and the main body (110) can move forward, backward, or rotate according to the operation of the left and right wheel motors.

The control unit (190) can control the movement of the robot cleaner (10) by controlling the driving unit (120) (e.g., wheel motor).

In one embodiment, the control unit (190) can control the driving unit (120) to move the robot cleaner (10) from the station (20) to the second position.

For example, when the robot cleaner (10) completes cleaning and returns to the station (20), the control unit (190) can control the driving unit (120) to move the robot cleaner (10) from the station (20) to the first position.

For example, based on the fact that the charging terminal (151) of the robot cleaner (10) and the charging terminal (218) of the station (20) are electrically connected, the control unit (190) can determine that the robot cleaner (10) is located at the first position in the station (20).

The control unit (190) can control the driving unit (120) to move the robot cleaner (10) to the second position in the station (20) based on the determination that the robot cleaner (10) is located at the first position in the station (20).

For example, based on the position sensor (183) of the robot cleaner (10) detecting the magnet (283) of the station (20), the control unit (190) can determine that the robot cleaner (10) is located at the second position in the station (20).

The control unit (190) can control the communication unit (190) of the robot cleaner (10) to transmit information to the communication unit (282) of the station (20) based on the determination that the robot cleaner (10) is located at the second position in the station (20).

The station (20) can transmit information received from the communication unit (282) of the robot cleaner (10) to the control unit (290) of the station (20), and the control unit (290) of the station (20) can control the suction motor (224) based on the information received from the communication unit (282). The control unit (290) can control the suction motor (224) to provide suction force to the waste suction unit (213).

The waste collected in the dust collection bin (141) of the robot cleaner (10) can be emptied by the suction motor (224) of the station (20).

When the process of emptying the dust collector (141) of the robot cleaner (10) is completed, the control unit (190) can control the driving unit (120) to move the robot cleaner (10) from the station (20) to the first position.

Based on the determination that the robot cleaner (10) is at the first position at the station (20), the control unit (290) of the station (20) can control the first pump (21), the first valve (23), and/or the second valve (24) for washing the mop (160). The control unit (290) of the station (20) can control the heating device (250) for sterilizing the mop (160). The control unit (290) of the station (20) can control the drying device (260) for drying the mop (160).

According to this configuration, the cleaning device (1) according to one embodiment of the present disclosure can enable the robot cleaner (10) to be more accurately positioned at the second position in the station (20). In addition, the cleaning device (1) according to one embodiment of the present disclosure can reduce contamination of the sewage suction port (213), sewage collection duct (225), and/or suction motor (224) due to moisture that may occur as a result of washing the sewage mop (160), since the robot cleaner (10) first discharges sewage collected in the dust bin (141) at the second position and then moves to the first position to wash the mop (160).

The brush motor (133) can rotate the brush (130).

The control unit (190) can control the brush motor (133) to rotate the brush (130) during dry cleaning, thereby causing foreign substances on the floor to be blown away by the brush (130).

The suction motor (142) can suck foreign substances scattered by the brush (130) into the dust collector (141) and rotate the suction fan that generates suction force to suck the foreign substances into the dust collector (141).

The control unit (190) can control the suction motor (142) to rotate the suction fan during dry cleaning, thereby allowing foreign substances scattered by the brush (130) to be drawn into the dust collector (141) through the suction port (111).

The robot cleaner (10) may include a rotation drive unit (161) that rotates the mop (160). The rotation drive unit (161) may include a motor. The rotation drive unit (161) may be referred to as a motor (161). For example, when the robot cleaner (10) is mounted on a station (20) and the mop (160) is being washed and/or sterilized, the motor (161) may rotate the mop (160). The control unit (190) of the robot cleaner (10) may control the motor (161) to rotate the mop (160).

The control unit (190) can rotate the mop (160) by controlling the rotation drive unit (161). The rotation drive unit (161) can include a motor for rotating the mop (160) and a driving circuit for driving the motor.

The robot cleaner (10) may include a lifting drive unit (162) that moves the mop (160) up and down. While the robot cleaner (10) is cleaning, the lifting drive unit (162) may move the mop (160) downward. As a result, the mop (160) may come into contact with the surface to be cleaned. While the robot cleaner (10) completes cleaning and returns to the station (20), the lifting drive unit (162) may move the mop (160) upward. As a result, the mop (160) may be separated from the surface to be cleaned. While the robot cleaner (10) is moving to the station (20), the mop (160) may be prevented from colliding with an obstacle on the surface to be cleaned or from leaving unnecessary moisture on the surface to be cleaned. As will be described later, the control unit (190) of the robot cleaner (10) can control the lifting drive unit (162) to move the mop (160) up and down.

The control unit (190) can raise or lower the mop (160) by controlling the lifting drive unit (162). That is, the control unit (190) can move the mop (160) by controlling the lifting drive unit (162). The lifting drive unit (162) can include an actuator that can move the mop (160).

The communication unit (182) can transmit data to an external device (e.g., a server, a user device, a station (20)) or receive data from an external device. To this end, the communication unit (182) can support the establishment of a direct (e.g., wired) communication channel or a wireless communication channel between external devices, and the performance of communication through the established communication channel. According to one embodiment, the communication unit (182) can include a wireless communication module (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module (e.g., a local area network (LAN) communication module, or a power line communication module). Any of these communication modules may communicate with an external device via a first network (e.g., a short-range communication network such as Bluetooth, WiFi (wireless fidelity) direct, or IrDA (infrared data association)) or a second network (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a local area network or a wide area network)). These various types of communication modules may be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips).

The short-range wireless communication module may include, but is not limited to, a Bluetooth communication module, a BLE (Bluetooth Low Energy) communication module, a near field communication module, a WLAN (Wi-Fi) communication module, a Zigbee communication module, an infrared (IrDA, infrared Data Association) communication module, a WFD (Wi-Fi Direct) communication module, an UWB (ultrawideband) communication module, an Ant+ communication module, a microwave (uWave) communication module, etc.

The remote communication module may include a communication module that performs various types of remote communication and may include a mobile communication interface. The mobile communication interface transmits and receives wireless signals with at least one of a base station, an external terminal, and a server on a mobile communication network.

In one embodiment, the communication unit (182) can communicate with external devices via a surrounding access point (AP). The access point (AP) can connect the local area network (LAN) to which the robot cleaner (10) is connected to a wide area network (WAN) to which the server is connected.
