[0028] (Implementation Method)

[0029] <1. Overall Structure of the Clothes Processing System>

[0030] Figure 1 This figure shows the overall configuration of a clothing treatment system 1 according to the first embodiment. The clothing treatment system 1 includes, for example, a washing machine 100, a server 200, and a home appliance management application AP in a terminal device 300. The network NW, described later, can utilize, for example, the Internet, a cellular network, a Wi-Fi network, a LPWA (Low Power Wide Area), a WAN (Wide Area Network), a LAN (Local Area Network), or other public or dedicated lines, depending on the circumstances.

[0031] The washing machine 100 is an electrical device used in the residence of the user U. The washing machine 100 is an example of a "clothing processing machine." A "clothing processing machine" broadly refers to a device that performs certain treatments on clothes (for example, one or more of washing, drying, wrinkle removal, crease reinforcement, deodorization, pollen removal, dust removal, or sterilization). A clothing processing machine is, for example, a washing machine, but a closet-type washing machine and the like also meet the requirements. In addition, in the present application, a "washing machine" may be a washing and drying machine with a drying function or a washing machine without a drying function. In addition, a drum washing machine is described below as an example of the washing machine 100. However, the washing machine 100 is not limited to a drum washing machine, but may also be a vertical washing machine, a twin-barrel washing machine, and the like.

[0032] Washing machine 100 is connected to network NW via a wireless router WR and a modem M installed in the home of user U. Washing machine 100 can communicate with server 200 or terminal device 300 via network NW. Washing machine 100 can also communicate directly with terminal device 300 via network NW or using short-range wireless communication such as Bluetooth (registered trademark).

[0033] The server 200 is a management server that manages the washing machine 100. The server 200 is composed of one or more server devices (e.g., cloud servers). The server 200 can communicate with the washing machine 100 or the terminal device 300 via the network NW. The server 200 may also include an information processing unit that performs edge computing or fog computing, such as an information processing unit included in a router in the network NW. The server 200 is not limited to a cloud server and may also be a computer located in the residence of the user U, or a home router (e.g., a wireless router WR).

[0034] The terminal device 300 is an electronic device used by the user U. The terminal device 300 is, for example, a portable terminal device such as a smartphone or a tablet terminal device. However, the terminal device 300 is not limited to a portable terminal device and may also be a personal computer, etc. The terminal device 300 includes, for example, a display device 301, an input device 302, and a communication unit 303.

[0035] The display device 301 has a display screen 301a that can display various information. The input device 302 can accept input from the user U. The input device 302 is, for example, a touch panel that is overlapped with the display screen 301a of the display device 301. The input device 302 may include a camera, a microphone, etc. provided in the terminal device 300. The communication unit 303 is a communication module that can perform wireless communication. The communication unit 303 is connected to the network NW via a wireless router WR and a modem M or directly. The communication unit 303 can communicate with the washing machine 100 or the server 200 via the network NW. In addition, as described above, the communication unit 303 can also communicate directly with the washing machine 100 via the network NW or using short-range wireless communication such as Bluetooth.

[0036] Application P is installed in terminal device 300 to support the functions described below. Application P is, for example, an application for managing washing machine 100. Hereinafter, the application software started by executing application P is referred to as "home appliance management application AP." Application P is an example of a "program."

[0037] <2. Overall structure of the washing machine>

[0038] Next, the overall structure of washing machine 100 will be described.

[0039] Figure 2 and Figure 3 1 is a front view showing the washing machine 100. Figure 2 and Figure 3 As shown, a door 12 that can be opened and closed is provided on the front surface of a housing 11 of the washing machine 100 . Figure 2Indicates a state (closed state) in which the door 12 is closed relative to the opening 11a of the box body 11 described later. Figure 3 The state (open state) in which the door 12 is opened relative to the opening 11a of the housing 11 is shown. The door 12 is an example of a "closing member."

[0040] The washing machine 100 is provided with a display / input unit 41. The display / input unit 41 includes a display unit 41a and an operating unit 41b. The display unit 41a is a display device that displays various information. The display unit 41a can be a liquid crystal display or an organic EL (Electro Luminescence) display having a display screen, or a lighting unit having a plurality of light-emitting diodes. The operating unit 41b is a functional unit that accepts operations from the user U related to the operation or reservation of the washing machine 100. The operating unit 41b can be a touch panel superimposed on the display unit 41a, or it can be a physical button or dial provided on the housing 11.

[0041] Washing machine 100, for example, is provided with a power button 45a as part of operating unit 41b. Power button 45a can accept an operation by user U to change the washing machine 100 from a power-on state (power-on state) to a power-off state (power-off state), or vice versa. In this application, "power-on state" refers to a state in which the main function of washing machine 100 (e.g., washing operation) can be performed. On the other hand, in this application, "power-off state" refers to a state in which all functions, including the communication function of communication unit 44, are disabled.

[0042] In this embodiment, when communication with the outside world via the communication unit 44 (described later) is set (for example, when online mode is set), the power button 45a can accept an operation by the user U to switch the washing machine 100 from the power-on state to the power-saving state (a standby state for remote operation). Furthermore, the power button 45a can accept an operation by the user U to switch the washing machine 100 from the power-saving state to the power-on state. The power-saving state is a state in which the main function of the washing machine 100 (for example, the washing operation) cannot be performed, but some functions, such as the communication function of the communication unit 44, can be maintained. The power button 45a is an example of a "power operation unit."

[0043] Washing machine 100 is provided with a start / pause button 45b as part of operating unit 41b, for example. Start / pause button 45b can receive an operation by a user U to start or temporarily stop the operation of washing machine 100.

[0044] like Figure 3As shown, a protrusion 71 is provided on the back of the door 12. In addition, a locking mechanism 13 is provided at a position of the housing 11 corresponding to the protrusion 71. When the door 12 is in the closed state, when the protrusion 71 engages with the locking mechanism 13, the door 12 is restricted to the closed state.

[0045] Figure 4 1 is a cross-sectional view showing washing machine 100. Washing machine 100 includes, for example, a housing 11, a door 12, a locking mechanism 13, a water tub 14, a drum 15, a motor 16, a water supply valve 21, a water filling box 22, a drain pipe 25, a drain valve 26, a main duct 31, a front duct 32, a fan housing 33, a blower 34, a rear duct 35, a heat pump 36, a display / input unit 41, a vibration sensor unit 42, a heat pump control unit 43, a communication unit 44, and a main control unit 50.

[0046] The housing 11 is a hollow housing. An opening 11a in the form of a through hole is formed on the front panel of the housing 11. A user U who uses the washing machine 100 can put clothes to be washed into the interior of the housing 11 through the opening 11a. A door 12 is mounted on the front panel of the housing 11. The door 12 closes the opening 11a in an openable and closable manner. The door 12 is an example of a "closing member". In addition, in the case of a vertical washing machine, a cover member that closes the opening 11a at the top of the housing 11 in an openable and closable manner is equivalent to an example of a "closing member".

[0047] The locking mechanism 13 is provided in association with the door 12. The locking mechanism 13 can transition between an unlocked state (open state) that allows the door 12 to be opened from a closed state, and a locked state (restricted state) that restricts the door 12 to the closed state. When the locking mechanism 13 is in the unlocked state (open state), the user U can, for example, manually open and close the door 12 freely. On the other hand, when the locking mechanism 13 is in the locked state (restricted state), the user U cannot open or close the door 12.

[0048] A tub 14 is fixed inside the housing 11. A drum 15 serving as a rotating tub is housed inside the tub 14. A motor 16 for rotating the drum 15 is fixed to a rear plate of the tub 14.

[0049] A water supply valve 21 is fixed inside the housing 11. The inlet of the water supply valve 21 is connected to a tap on the water main. The water supply valve 21 switches between an open and closed state depending on the rotational speed of the motor included in the water supply valve 21. The outlet of the water supply valve 21 is connected to a water filling box 22. The water filling box 22 has a cylindrical water filling port 22a. The water filling port 22a is inserted into the water storage tub 14. Tap water injected from the water supply valve 21 into the water filling box 22 flows through the water filling port 22a into the water storage tub 14.

[0050] The upper end of the drain pipe 25 is connected to the water receiving tub 14. The drain pipe 25 is provided with a drain valve 26. The drain valve 26 switches between an open state and a closed state according to the rotation amount of the motor provided in the drain valve 26.

[0051] A main duct 31 is fixed to the bottom plate of the housing 11. The lower end of a front duct 32 is connected to the front end of the main duct 31. The upper end of the front duct 32 is connected to the interior of the tub 14. A fan housing 33 is fixed to the rear end of the main duct 31. A blower 34 is mounted in the fan housing 33. The lower end of a rear duct 35 is connected to the exhaust port of the fan housing 33. The upper end of the rear duct 35 is connected to the tub 14.

[0052] A heat pump 36 is provided inside the housing 11. The heat pump 36 is a heating device having a compressor 36a and provided in the main duct 31. The heat pump 36 heats the dry air passing through the main duct 31. Alternatively, the washing machine 100 may include a heater for heating the dry air instead of the heat pump 36.

[0053] The display / input unit 41 is provided in the housing 11. The display / input unit 41 includes the above-mentioned display portion 41a and the operation portion 41b.

[0054] The vibration sensor unit 42 is provided in the tub 14 and is a sensor unit that detects vibrations of the tub 14. For example, the vibration sensor unit 42 detects acceleration acting on the tub 14. The heat pump control unit 43 is provided in association with the heat pump 36 and is a control unit that controls the heat pump 36. The heat pump control unit 43 controls the operation of the heat pump 36 (for example, the operation of the compressor 36a) based on the detection result of the temperature of the dry air passing through the main duct 31.

[0055] Communication unit 44 is capable of communicating with the outside of washing machine 100. For example, communication unit 44 is a communication module (e.g., a network adapter) for communicating with external server 200. Communication unit 44 transmits and receives information related to washing machine 100 to and from server 200. Communication unit 44 is connected to network NW via a wireless router WR and modem M installed in the same residence of user U as washing machine 100, and is capable of communicating with server 200 via network NW.

[0056] Communication unit 44 transmits and receives predetermined information to and from server 200. Information transmitted from communication unit 44 to server 200 includes information such as the status, operation history, and abnormality information of washing machine 100. Meanwhile, information transmitted from server 200 to communication unit 44 includes, for example, information related to operations performed by user U using terminal device 300. Examples of such information include information transmitted from server 200 to communication unit 44, settings for scheduled operation of washing machine 100, operations for turning on washing machine 100, and operations for starting operation of washing machine 100.

[0057] Furthermore, in the present application, "operation in a manner that the power is turned on" refers broadly to an operation that makes the power appear to be turned on when viewed from the user U. For example, in the present application, "operation in a manner that the power is turned on" is not limited to an operation that changes the washing machine 100 from a power-off state (power-off state) to a power-on state (power-on state), but may also be equivalent to an operation that returns from a power-saving state (standby state) to a normal state (normal power-on state). From another perspective, in the present application, "operation in a manner that the power is turned on" refers to supplying power related to at least some of the multiple functions of the washing machine 100 (e.g., a function for performing a washing operation) for which the power is turned off in the power-saving state (standby state).

[0058] Similarly, in the present application, “operation in a manner that cuts off the power” broadly refers to an operation that appears to be power off when viewed from the user U. For example, in the present application, “operation in a manner that cuts off the power” is not limited to an operation that changes the washing machine 100 from a power-on state (power-on state) to a power-off state (power-off state), but may also be equivalent to an operation for changing from a normal state (normal power-on state) to a power-saving state (standby state). From another perspective, in the present application, “operation in a manner that cuts off the power” means stopping the power supply related to at least some of the multiple functions of the washing machine 100 (for example, a function for performing a washing operation) for which the power is cut off in the power-saving state (standby state).

[0059] The communication unit 44 is a component that can independently control the power supply of the main function of the washing machine 100 (e.g., the power supply of the main microcomputer 52) (capable of turning the power supply into an off-state). For example, the washing machine 100 can be set to a mode (offline mode) in which it does not communicate with the server 200 based on an operation by the user U. When the washing machine 100 is set to offline mode, the main microcomputer 52 sends a signal to the communication unit 44 to turn the power supply of the communication unit 44 into an off-state. Upon receiving this signal, the communication unit 44 turns the power supply of the communication unit 44 into an off-state. As a result, the power supply of the main function of the washing machine 100 remains on, while the power supply of the communication unit 44 is turned off.

[0060] The main control unit 50 is a control unit that centrally controls the entire washing machine 100. It includes a circuit board 51 and a main microcomputer 52. Main microcomputer 52 is mounted on circuit board 51. Main microcomputer 52 centrally controls the entire washing machine 100. Main microcomputer 52 controls the locking mechanism 13, motor 16, water supply valve 21, drain valve 26, blower 34, display / input unit 41, heat pump control unit 43, and communication unit 44, among other functions.

[0061] <3. Locking mechanism>

[0062] Next, the locking mechanism 13 will be described.

[0063] Figure 5 and Figure 6 It is a plan view schematically showing the locking mechanism 13 . Figure 5 Indicates unlocked status. Figure 6 Indicates the locked state.

[0064] like Figure 5 and Figure 6 As shown, the lock mechanism 13 includes, for example, an opening / closing detection switch 80 , an engaging portion 81 , a solenoid 82 , an actuator 83 , a spring 84 , a lock pawl 85 , a lock pawl movable mechanism 86 , a lock detection switch 87 , and a spring 88 .

[0065] The opening and closing detection switch 80 is a sensor that detects the opening and closing state of the door 12. For example, when the door 12 is closed, the protrusion 80a of the opening and closing detection switch 80 abuts against the door 12, and the opening and closing detection switch 80 is turned on (refer to Figure 6 On the other hand, when the door 12 is open, the protrusion 80a of the opening and closing detection switch 80 is separated from the door 12, and the opening and closing detection switch 80 is turned into the OFF state (refer to Figure 5 The state of the opening and closing detection switch 80 changes according to the opening and closing state of the door 12, thereby being able to sense the opening and closing state of the door 12. In addition, the opening and closing detection switch 80 can also be provided as an external structure of the locking mechanism 13.

[0066] The engaging portion 81 is in the closed state and engages with the protruding portion 71 of the door 12 (see Figure 3 ) is engaged. A locking claw 85 is provided in the engaging portion 81. The locking claw 85 is urged in the direction of arrow Q1 by a spring 88. When the locking mechanism 13 is in the unlocked state (refer to Figure 5 ), the locking claw 85 is located at a position disengaged from the engaging portion 81. The locking claw 85 moves up and down in conjunction with the movement of the actuator 83 via the locking claw movable mechanism 86.

[0067] The movable piece 82a of the solenoid 82 is connected to the actuator 83, causing the actuator 83 to move in the direction indicated by arrow P1. The actuator 83 includes a knock cam mechanism. The knock cam mechanism alternately changes between a first position L1 and a second position L2, applying a force to the actuator 83 and returning to the position to which it returns. The actuator 83 is biased in the direction indicated by arrow P2 by a spring 84.

[0068] When the locking mechanism 13 is in the unlocked state (see Figure 5 ), due to the tension of the spring 88, the locking claw 85 is located at a position disengaged from the engaging portion 81. From this state, the movable piece 82a of the solenoid 82 causes the action member 83 to move in the direction of the arrow P1. When the action member 83 moves to the second position L2, as shown in FIG. Figure 6 As shown, the lock claw 85 is moved in the direction of arrow Q2 by the lock claw movable mechanism 86. As a result, the lock claw 85 projects into the engagement portion 81, and the lock mechanism 13 is switched to the locked state.

[0069] On the other hand, when the solenoid 82 stops driving, the actuator 83 tends to return to the direction of arrow P2 due to the tension of the spring 84. At this time, each time the solenoid 82 is driven by the knock cam mechanism, the position where the actuator 83 returns alternately changes between the first position L1 and the second position L2. Figure 5 ) changes to the locked state (refer to Figure 6 ), the position where the actuator 83 returns is limited to the second position L2. In this case, the locking claw 85 continues to protrude into the engaging portion 81, and even if the power supply to the locking mechanism 13 (for example, the power supply to the solenoid 82) is stopped at this moment, the locking mechanism 13 maintains the locked state.

[0070] from Figure 6 From the locked state shown, the movable piece 82a of the solenoid 82 moves the action member 83 in the direction of the arrow P1. When the drive of the solenoid 82 is stopped, the action member 83 returns to the direction of the arrow P2 due to the tension of the spring 84. Figure 6 ) to the unlocked state (refer to Figure 5 ) transition, the action member 83 returns to the first position L1. In this case, as Figure 5 As shown, the locking claw 85 becomes disengaged from the engaging portion 81, and the locking mechanism 13 is changed to the unlocked state. Figure 6 ) changes to the unlocked state (refer to Figure 5), the return position of the actuator 83 is restricted to the first position L1. In this case, the lock claw 85 continues to be disengaged from the engaging portion 81, and even if the power supply to the lock mechanism 13 (for example, the power supply to the solenoid 82) is stopped at this moment, the lock mechanism 13 is maintained in the unlocked state.

[0071] Thus, each time the solenoid 82 is driven, the locking mechanism 13 alternately switches between a locked state in which the locking claw 85 projects into the engaging portion 81 and an unlocked state in which the locking claw 85 is disengaged from the engaging portion 81. Furthermore, the locked state or the unlocked state is maintained even after the power supply to the solenoid 82 is cut off.

[0072] The lock detection switch 87 switches between an on state and an off state according to the state of the lock mechanism 13 (eg, the position of the action member 83). Figure 5 As shown, when the locking mechanism 13 is in the unlocked state, the operating member 83 is in the first position L1, and the lock detection switch 87 is in the off state. On the other hand, when the locking mechanism 13 is in the locked state, the operating member 83 is in the second position L2, and the lock detection switch 87 is in the on state. Thus, whether the locking mechanism 13 is in the locked or unlocked state can be determined based on the state of the lock detection switch 87.

[0073] <4. Display and Input System>

[0074] Next, the display and input system will be described.

[0075] In this embodiment, a display / input unit 41 is provided on the housing 11 of the washing machine 100. In addition, the housing 11 of the washing machine 100 is provided with a power button 45a and a start / pause button 45b.

[0076] Figure 7 1 is a diagram showing a display and input system configured on the main body of the washing machine 100. Figure 7 As shown, the display / input unit 41 is provided with a plurality of operation buttons B as a plurality of operation sections. For example, the display / input unit 41 includes a bath water setting button B1, a warm water setting button B2, a detergent usage amount setting button B3, a softener usage amount setting button B4, and a reservation setting button B5 as part of the plurality of operation buttons B. Furthermore, the display / input unit 41 also includes a wash cycle setting button B6, a rinse cycle setting button B7, a spin cycle setting button B8, a drying cycle setting button B9, a wash operation selection button B10, a wash and dry operation selection button B11, and a drying operation selection button B12 as part of the plurality of operation buttons B.

[0077] Furthermore, a remote standby button B13 is provided on the display / input unit 41 as part of the operation buttons B. The remote standby button B13 is used to switch the washing machine 100 to a special state (special standby state) for remote operation. This special state does not accept input from the user U to the operating units (operation unit 41b, power button 45a, and start / pause button 45b) provided on the housing 11 of the washing machine 100, but instead accepts external operations via the communication unit 44.

[0078] The display / input unit 41 is provided with a display area D. Various setting states and operating states are displayed in the display area D. The display area D also displays the scheduled setting time, the end time of washing and drying, and various warnings.

[0079] Furthermore, washing machine 100 can be operated using terminal device 300 by communicating with terminal device 300 via server 200 , for example. Figure 8 This is a diagram showing a display screen 301a of the terminal device 300. When the home appliance management application AP of the terminal device 300 is started, the display Figure 8 The display of the operation unit described below and the acceptance of the operation of the user U on the displayed operation unit are performed by the home appliance management application AP.

[0080] like Figure 8 As shown, the screen of terminal device 300 displays a washing program setting button 311a, a reservation setting button 311b, a wash / softener setting button 311c, a power button 311d, and a start / pause button 311e as an operation unit for accepting operations by user U. Furthermore, washing program setting buttons 311a, reservation setting buttons 311b, and wash / softener setting buttons 311c are arranged in a hierarchical structure, and pressing each of buttons 311a to 311c displays a more detailed setting screen.

[0081] Power button 311d is a button that can accept the same operations as power button 45a of washing machine 100. For example, when communication with the outside world via communication unit 44 is set (for example, when wireless router WR is set to be used), power button 311d can accept an operation from user U to switch washing machine 100 from the power-on state to the power-saving state (remote operation standby state). Power button 311d can also accept an operation from user U to switch washing machine 100 from the power-saving state (standby state) to the power-on state.

[0082] Start / pause button 311e is a button that can accept the same operation as start / pause button 45b. For example, start / pause button 311e can accept an operation by a user U to start or temporarily stop the operation of washing machine 100.

[0083] Thus, in this embodiment, the power on / off operation and the start / pause operation of the washing machine 100 can be performed through the power button 45a and the start / pause button 45b of the washing machine 100 body, and can be performed using the power button 311d and the start / pause button 311e of the terminal device 300.

[0084] <5. Control System>

[0085] Next, the control system will be described.

[0086] Figure 9 1 is a block diagram showing the structure of the control system of the washing machine 100. Figure 9 As shown, the communication unit 44 is connected to the control unit 52. The communication unit 44 transmits the transmission data TXD from the control unit 52 to the terminal device 300. Furthermore, the communication unit 44 transmits the reception data RXD received from the external terminal device 300 to the control unit 52. Furthermore, the communication unit 44 can transmit a power saving state release signal Wake_UP to the control unit 52. Upon receiving the power saving state release signal Wake_UP, the control unit 52 transitions from the power saving state (remote operation standby state) to the normal state.

[0087] The display / input unit 41 is connected to the control unit 52. The display / input unit 41 includes a display unit 41a and an operation unit 41b. Operation input signals are sent from the operation unit 41b to the control unit 52. In addition, the control unit 52 sends display signals to the display unit 41a.

[0088] Furthermore, an operation signal related to power on and power off is transmitted from the power button 45a to the control unit 52. Furthermore, an operation signal related to start and pause is transmitted from the start / pause button 45b to the control unit 52.

[0089] Furthermore, the control unit 52 is connected to the opening / closing detection switch 80, the lock detection switch 87, and the solenoid 82 of the locking mechanism 13. The control unit 52 determines the open / closed state of the door 12 based on the state of the opening / closing detection switch 80. The control unit 52 determines whether the locking mechanism 13 is in the unlocked state or the locked state based on the state of the lock detection switch 87. The control unit 52 drives the solenoid 82 to change the locking mechanism 13 to the locked state or the unlocked state.

[0090] In this embodiment, the lock detection switch 87 is disposed in the power supply path between the communication power supply unit 92 and the communication unit 44. This is to restrict the operation of the communication unit 44 when the lock mechanism 13 is in the unlocked state. This will be described later.

[0091] The control unit 52 also controls the washing / drying unit 95. The washing / drying unit 95 controls the motor 16, heat pump 36, water supply valve 21, drain valve 26, etc. according to the operation mode and the preset setting, and performs various processes during the washing and drying operations.

[0092] In addition, the control unit 52 controls the power supply unit 90. The power supply unit 90 includes a main power supply unit 91 and a communication power supply unit 92. The main power supply unit 91 generates power for each unit required for the operation of the main functions of the washing machine 100 from the commercial power supply 96. The communication power supply unit 92 generates power required for the communication unit 44. The communication power supply unit 92 can set the power on / off independently of the main power supply unit 91. The communication power supply unit 92 can supply power to the communication unit 44 via the lock detection switch 87, for example. In addition, the communication power supply unit 92 can supply power to the functional units related to communication in the control unit 52 (main microcomputer 52). A battery can also be used as the communication power supply unit 92.

[0093] When washing machine 100 is in power-saving mode (standby mode for remote operation), power supply to various components of washing machine 100 (such as motor 16 and heat pump 36) is stopped, and power supply to display unit 41a and operation unit 41b is also stopped. Furthermore, when washing machine 100 is in power-saving mode (standby mode for remote operation), power supply to related functions such as the clock oscillator circuit used for control of main microcomputer 52 is also stopped.

[0094] When washing machine 100 is powered on, power is supplied to each component of washing machine 100 and also to display unit 41a and operation unit 41b.

[0095] In addition, the control unit 52 performs processing for realizing the following functions. (1) When the power button 45a of the washing machine 100 is operated in a manner to cut off the power, the control unit 52 changes the locking mechanism 13 to the locked state and maintains the communication function of the communication unit 44. For example, when communication with the outside is set through the communication unit 44 (for example, when the online mode is set), when the power button 45a of the washing machine 100 is operated in a manner to cut off the power, the control unit 52 drives the solenoid 82 to change the locking mechanism 13 to the locked state, and changes the washing machine 100 from the power-on state to the power-saving state. On the other hand, when communication with the outside is not set through the communication unit 44 (for example, when the offline mode is set), when the power button 45a of the washing machine 100 is operated in a manner to cut off the power, the control unit 52 changes the washing machine 100 from the power-on state to the power-off state while maintaining the locking mechanism 13 in the unlocked state.

[0096] (2) When the power button 45a of the washing machine 100 is operated to shut off the power, and the door 12 is detected to be open by the opening / closing detection switch 80, the control unit 52 does not accept the operation to shut off the power, but instead notifies the user of an abnormality. For example, as an example of notifying the abnormality, the control unit 52 causes the display unit 41a to display a warning indicating that the door 12 is open, or outputs a warning indicating that the door 12 is open by voice from a speaker provided in the washing machine 100 (or a separate voice communication device).

[0097] (3) When the power button 45a of the washing machine 100 is operated to turn on the power, the control unit 52 changes the lock mechanism 13 from the locked state to the unlocked state.

[0098] (4) When the locking mechanism 13 is in the locked state, if the power button 45a of the washing machine 100 is operated to turn on the power, the control unit 52 changes the locking mechanism 13 from the locked state to the unlocked state. On the other hand, when the locking mechanism 13 is in the locked state and in the above-mentioned special standby state, if the power button 45a of the washing machine 100 is operated to turn on the power, the control unit 52 does not accept the operation and maintains the locking mechanism 13 in the locked state.

[0099] (5) When the lock mechanism 13 is in the locked state, if the power button 45a of the washing machine 100 is operated to turn on the power, the control unit 52 changes the lock mechanism 13 from the locked state to the unlocked state. On the other hand, if a predetermined operation (e.g., an operation to turn on the power of the washing machine 100 using the terminal device 300) is received from the outside via the communication unit 44 and the predetermined operation is performed while being restricted by the restriction unit 60 (described later), the control unit 52 maintains the lock mechanism 13 in the locked state.

[0100] (6) When a prescribed operation (e.g., an operation of turning on the power of the washing machine 100 using the terminal device 300) is received from the outside via the communication unit 44 and the prescribed operation is performed in a state restricted by the restriction unit 60 (described later), and when the following prescribed conditions are satisfied, the control unit 52 may change the locking mechanism 13 from the locked state to the unlocked state. The prescribed conditions are conditions associated with the user U being within a prescribed distance (e.g., a certain distance) from the washing machine 100. The prescribed conditions associated with the user U being within the prescribed distance from the washing machine 100 may be satisfied, for example, when communication with the terminal device 300 is completed within the user U's home using the wireless router WR, when the location information of the terminal device 300 (e.g., location information using GNSS (Global Navigation Satellite System)) corresponds to the user U's home, etc. In addition, the prescribed conditions associated with the user U being within the prescribed distance from the washing machine 100 may be satisfied, for example, when the user U is detected by a human sensor installed in the washing machine 100 or other household appliances, when the use of other household appliances arranged in the same household is detected in the most recent time period within the prescribed time period, etc.

[0101] (7) The control unit 52 can transition to a special state (special standby state) in which it does not accept inputs to the operating units (operating unit 41b, power button 45a, or start / pause button 45b) of the washing machine 100, but accepts operations from the outside via the communication unit 44. In this special state, when the locking mechanism 13 is in the locked state, operations from the terminal device 300 via the communication unit 44 are accepted.

[0102] <6. Restrictions>

[0103] Next, the restriction portion 60 will be described.

[0104] like Figure 9 As shown, the lock detection switch 87 is arranged in the power supply path between the communication power supply unit 92 and the communication unit 44. Thus, an example of the restriction unit 60 is realized.

[0105] Restriction unit 60 permits acceptance of a predetermined operation from the outside via communication unit 44 when locking mechanism 13 is in the locked state, and restricts acceptance of the predetermined operation via communication unit 44 when locking mechanism 13 is in the unlocked state. For example, restriction unit 60 restricts acceptance of the predetermined operation via communication unit 44 in conjunction with the change of locking mechanism 13 from the locked state to the unlocked state. Here, the predetermined operation may be, for example, an operation to turn on the power of washing machine 100 using terminal device 300 or an operation to start operation of washing machine 100 using terminal device 300.

[0106] In the present embodiment, the communication power supply unit 92 can be controlled independently of the main power supply unit 91. The communication power supply unit 92 can be moved even in a state where power is not supplied from the main power supply unit 91 (the power saving state described above).

[0107] When the lock mechanism 13 is locked, the lock detection switch 87 is turned on. Therefore, the power supply Vdd is supplied from the communication power supply unit 92 to the communication unit 44. This activates the communication unit 44 and enables it to receive operation signals inputted from the terminal device 300 via the communication unit 44.

[0108] On the other hand, when the lock mechanism 13 transitions from the locked state to the unlocked state, the lock detection switch 87 is turned off. Consequently, power is not supplied to the communication unit 44. As a result, the communication unit 44 is no longer operational, limiting the acceptance of operation signals input from the terminal device 300 via the communication unit 44.

[0109] Thus, the restricting unit 60 includes a lock detection switch 87 (switching unit), the physical or electrical state of which changes between when the locking mechanism 13 is unlocked and when it is locked. Furthermore, the communication unit 44 transitions between a first state that permits the acceptance of the aforementioned prescribed operation and a second state that restricts the acceptance of the aforementioned prescribed operation, depending on the state of the lock detection switch 87. Furthermore, the lock detection switch 87 (switching unit) can be any component that changes at least one of its physical or electrical state between when the locking mechanism 13 is unlocked and when it is locked. Furthermore, the switching unit may be a component located external to the locking mechanism 13.

[0110] In this embodiment, the second state is a state in which the predetermined operation is restricted by restricting communication of the communication unit 44. In this embodiment, the second state is a state in which communication of the communication unit 44 is restricted by cutting off power supply to the communication unit 44.

[0111] Furthermore, the communication power supply unit 92 can be controlled independently of the main power supply unit 91 and can operate even in the aforementioned power-saving state (standby state for remote operation). Furthermore, even after the power supply to the locking mechanism 13 is stopped, the locking mechanism 13 remains locked or unlocked. Therefore, the restricting unit 60 can control the operation of the communication unit 44 even in the aforementioned power-saving state (standby state for remote operation).

[0112] <7. Control Process>

[0113] Next, the control flow of this embodiment will be described.

[0114] In this embodiment, the operations of turning on the power of the washing machine 100, turning off the power of the washing machine 100, starting the operation of the washing machine 100, and temporarily stopping the operation of the washing machine 100 can be performed through the power button 45a and the start / pause button 45b of the washing machine 100, and can be performed using the power button 311d and the start / pause button 311e of the terminal device 300.

[0115] Figure 10 This is a flowchart showing the control flow when an operation is performed by the terminal device 300 in this embodiment. When the washing machine 100 receives the above-mentioned predetermined operation from the terminal device 300, it enters the power saving state (remote operation standby state) (step S1). In the standby state, the main power supply unit 91 is turned off.

[0116] User U using washing machine 100 operates power button 311d of terminal device 300 to turn on the power of washing machine 100 (step S2). When power button 311d of terminal device 300 is operated, an operation signal for turning on the power (an operation signal for turning on the power of washing machine 100) is transmitted from terminal device 300 to washing machine 100 via server 200.

[0117] When the power button 311d of the terminal device 300 is operated to turn on the power, the process branches depending on whether the lock mechanism 13 is locked (step S3). Specifically, if the lock mechanism 13 of the washing machine 100 is locked (step S3: Yes), the lock detection switch 87 is turned on, and power is supplied from the communication power supply unit 92 to the communication unit 44. Conversely, if the lock mechanism 13 of the washing machine 100 is unlocked (step S3: No), the lock detection switch 87 is turned off, and power is not supplied from the communication power supply unit 92 to the communication unit 44.

[0118] Thus, if the locking mechanism 13 is locked (step S3: Yes), the communication unit 44 receives a power-on operation signal, and the washing machine 100 is switched to the power-on state (step S4). During this operation, for example, the communication unit 44 transmits a power-saving state release signal Wake_UP to the control unit 52. In response to this power-saving state release signal Wake_UP, the control unit 52 switches from the power-saving state to the normal state. The communication unit 44 then transmits a power-on operation signal to the control unit 52, switching the washing machine 100 to the power-on state. When the power-on operation is completed, the main power supply unit 91 is activated, supplying power to various components.

[0119] On the other hand, if the lock mechanism 13 is in the unlocked state (step S3 : No), the communication unit 44 cannot receive the power-on operation signal (step S5 ), and thus the process ends.

[0120] Next, user U using washing machine 100 presses start / pause button 311e of terminal device 300 to start operation of washing machine 100 (step S6). When start / pause button 311e of terminal device 300 is pressed, an operation signal for starting operation is transmitted from terminal device 300 to washing machine 100 via server 200.

[0121] When the start / pause button 311e of the terminal device 300 is operated to indicate the start of operation, the process branches depending on whether the lock mechanism 13 is in the locked state (step S7). For example, if the lock mechanism 13 of the washing machine 100 is in the locked state (step S7: Yes), the lock detection switch 87 is turned on, and power is supplied from the communication power supply unit 92 to the communication unit 44. In contrast, if the lock mechanism 13 of the washing machine 100 is in the unlocked state (step S7: No), the lock detection switch 87 is turned off, and power is not supplied from the communication power supply unit 92 to the communication unit 44.

[0122] Thus, if locking mechanism 13 is in the locked state (step S7 : YES), communication unit 44 can receive the operation signal for starting the operation, and start the operation of washing machine 100 (step S9 ).

[0123] On the other hand, if the lock mechanism 13 is in the unlocked state (step S7 : NO), the communication unit 44 cannot receive the operation signal for starting the operation in step S5 (step S8 ), and the process ends.

[0124] Thus, in this embodiment, when the locking mechanism 13 is in the locked state (open state), the power supply to the communication unit 44 is stopped, and the communication unit 44 cannot receive an operation signal from the outside. This ensures safety even in an environment where the user U using the washing machine 100 cannot confirm the surroundings of the washing machine 100.

[0125] Next, the processing of the control unit 52 when the power-on operation is performed will be described.

[0126] Figure 11 1 is a flowchart showing the flow of processing by the control unit 52 when the power-on operation is performed.

[0127] Washing machine 100 enters a power saving state (a standby state for remote operation) (step S101) when receiving the above-mentioned predetermined operation from terminal device 300. In the standby state, main power supply unit 91 is turned off.

[0128] Control unit 52 determines whether a power-on operation has been performed (step S102 ). The power-on operation may be performed by power button 45 a on washing machine 100 or by power button 311 d on terminal device 300 .

[0129] When the control unit 52 determines that the power-on operation has been performed, it determines whether the power-on operation was performed by power button 45a of washing machine 100 or by remote operation of operation button 311d of terminal device 300 (step S103). If the power-on operation was performed by power button 45a of washing machine 100 (step S103: Yes), the control unit 52 switches the locking mechanism 13 to the unlocked state (step S106) and switches the washing machine 100 to the power-on state (step S107).

[0130] When the power button 311d of the terminal device 300 is turned on (step S103: No), the control unit 52 determines whether the user U is within a predetermined distance from the washing machine 100 (step S104). If the user U is within the predetermined distance (step S104: Yes), the control unit 52 unlocks the locking mechanism 13 (step S106) and turns the washing machine 100 on (step S107).

[0131] On the other hand, if there is no user U within the predetermined distance (step S104 : No), the control unit 52 maintains the lock mechanism 13 in the locked state (step S105 ) and turns the washing machine 100 to the power-on state (step S107 ).

[0132] Thus, when the power button 45a on the washing machine 100 is turned on (steps S102 and S103: Yes), the control unit 52 unlocks the locking mechanism 13 (step S106). Thus, once the user U turns on the power, the door 12 is opened and washing and drying operations can be immediately performed.

[0133] Furthermore, when the power button 311 d of the terminal device 300 is operated to turn on the power (step S103 : No), the lock mechanism 13 is maintained in the locked state (step S105 ), thereby ensuring safety.

[0134] Furthermore, even if the power is turned on by operating the terminal device 300, the user U can check the surrounding conditions of the washing machine 100 as long as the user U is near the washing machine 100. Therefore, even if the power is turned on by operating the terminal device 300, if the user U is near the washing machine 100 (step S104: Yes), the control unit 52 unlocks the locking mechanism 13 (step S105).

[0135] Next, the processing of the control unit 52 when the power-off operation is performed will be described.

[0136] Figure 12 1 is a flowchart showing the flow of processing by the control unit 52 when a power-off operation is performed.

[0137] The control unit 52 determines whether a power-off operation has been performed (step S201 ).

[0138] If the control unit 52 determines that a power-off operation has been performed (step S201: Yes), it then determines whether the communication setting is on (i.e., whether the mode is online or offline) (step S202). If the communication state is off (offline mode) (step S202: No), the control unit 52 performs a power-off process, and switches the washing machine 100 to the power-off state (step S208).

[0139] If the communication state is on (in online mode) (step S202: Yes), the control unit 52 determines whether the power off operation was performed using the power button 45a of the washing machine 100 or by remote operation using the operation button 311d of the terminal device 300 (step S203). If the power off operation was performed by remote operation using the operation button 311d of the terminal device 300 (step S203: No), the control unit 52 maintains the locking mechanism 13 in the locked state (step S206), performs the power off process, and shifts the washing machine 100 to the power saving state (remote operation standby state) (step S207).

[0140] When the power button 45a of the washing machine 100 body is turned off (step S203: Yes), the control unit 52 determines whether the door 12 is open based on the state of the opening / closing detection switch 80 (step S204).

[0141] When the control unit 52 determines that the door 12 is in the open state (step S204 : Yes), it displays an abnormality indicating that the door 12 is open on the display unit 41 a and notifies the user U (step S205 ).

[0142] When the control unit 52 determines that the door 12 is closed (step S204: No), it switches the locking mechanism 13 to the locked state (step S206), performs power off processing, and switches the washing machine 100 to the power saving state (remote operation standby state) (step S207).

[0143] Thus, when the power button 45a of the washing machine 100 is turned off, if the door 12 is open (step S204: Yes), the display unit 41a displays a message indicating that the door 12 is open (step S205). The user U is urged to close the door 12 by viewing this message.

[0144] If the power button 45a of the washing machine 100 is turned off (step S203: Yes), the locking mechanism 13 is locked (step S206). If the power button 311d of the terminal device 300 is turned off (step S203: No), the locking mechanism 13 remains locked. Thus, in the power-off standby state, the locking mechanism 13 is locked, ensuring safety.

[0145] If the communication setting is off (offline mode) (step S202 : Yes), the user U does not remotely operate the washing machine 100 , and therefore the lock mechanism 13 is not set to the locked state.

[0146] Figure 13 This is an example of a notification displayed when the power is turned off in the state where the door 12 is open in step S205. Figure 13 As shown, a notification D1 urging closing of the door 12 is displayed in the display area D of the display portion 41 a of the display / input unit 41 .

[0147] Furthermore, when the door 12 is locked, if it is necessary to open the door 12, for example, by a specific operation on the operating portion 41b, the locking mechanism 13 can be changed from the locked state to the unlocked state. Figure 14As shown, a notification D2 confirming the opening of door 12 is displayed in display area D of display unit 41a of display / input unit 41. In addition, considering children's mischief, the lock release can be set as a special operation method such as pressing multiple buttons at the same time or setting the number of times a button is pressed. The specific operation on operation unit 41b is an example of "an operation different from the operation of turning on the power." In addition, notification D2 confirming the opening of door 12 can also be displayed on display screen 301a of terminal device 300 instead of or in addition to display unit 41a of display / input unit 41. In this case, user U can also send an operation signal allowing the opening of door 12 from terminal device 300 to washing machine 100 via server 200.

[0148] <8. Remote Standby>

[0149] Depending on the usage pattern of user U, operation of washing machine 100 may be prioritized in terminal device 300 . Therefore, in this embodiment, input from washing machine 100 is not accepted, but input from terminal device 300 via communication unit 44 is accepted.

[0150] That is, Figure 7 As shown, a remote standby button B13 is provided on the display / input unit 41. By pressing the remote standby button B13, a special state (special standby state) can be entered. In the special state, when the locking mechanism 13 is locked, the terminal device 300 receives an operation signal from the outside via the communication unit 44.

[0151] <8. Modifications>

[0152] Furthermore, in the above-described configuration, the limiting unit 60 supplies or cuts off power to the communication unit 44 based on the state of the lock detection switch 87, thereby transitioning to a first state in which the communication unit 44 is allowed to accept a specified operation, or a second state in which acceptance of the specified operation is restricted. However, this configuration is not limited thereto. For example, power may be continuously supplied to the communication unit 44 even in the standby state, and data communication by the communication unit 44 may be enabled or restricted based on the state of the lock detection switch 87, thereby transitioning to the first state in which acceptance of the specified operation is allowed, or the second state in which acceptance of the specified operation is restricted. Furthermore, the communication line between the communication unit 44 and the control unit 52 may be connected or disconnected based on the state of the lock detection switch 87. For example, in the second state described above, instead of cutting off power to the communication unit 44, communication between the control unit 52 and the communication unit 44 may be restricted (e.g., the control unit 52 does not accept signals from the communication unit 44), thereby restricting communication by the communication unit 44.

[0153] <9. Advantages>

[0154] In this embodiment, the washing machine 100 includes a housing 11, a door 12, a locking mechanism 13, a communication unit 44, a control unit 52, and a restriction unit 60. The housing 11 has an opening 11a into which clothes can be put. The door 12 closes the opening 11a in an openable and closable manner. The locking mechanism 13 is capable of switching between an open state that allows the door 12 to change from a closed state to an open state and a restricted state that restricts the door 12 to a closed state. The communication unit 44 is capable of communicating with the outside of the washing machine 100. The control unit 52 controls the locking mechanism 13 and the communication unit 44. The restriction unit 60 allows the acceptance of a prescribed operation from the outside via the communication unit 44 when the locking mechanism 13 is in the restricted state, and restricts the acceptance of a prescribed operation via the communication unit 44 when the locking mechanism 13 changes from the restricted state to the open state. According to such a configuration, when the locking mechanism 13 is in the open state, the acceptance of a prescribed operation from the outside via the communication unit 44 is restricted. Therefore, even in an environment where the user U using the washing machine 100 cannot check the surroundings of the washing machine 100 , it is possible to ensure safety and perform predetermined operations from the outside, thereby improving the convenience of the washing machine 100 .

[0155] In this embodiment, the restricting portion 60 restricts the acceptance of a predetermined operation via the communication portion 44 in conjunction with the change of the lock mechanism 13 from the restricted state to the released state. With this configuration, the washing machine 100 can more reliably restrict the acceptance of a predetermined operation from the outside via the communication portion 44 when the lock mechanism 13 is in the released state.

[0156] In this embodiment, the restricting unit 60 includes a lock detection switch 87 (a switching unit). The physical or electrical state of this lock detection switch 87 changes depending on whether the locking mechanism 13 is in the open state or the restricted state. Based on the state of the lock detection switch 87, the restricting unit 60 transitions between a first state that permits acceptance of a specified operation and a second state that restricts acceptance of the specified operation. With this configuration, even when the washing machine 100 is in a power-off standby state, it is possible to reliably determine whether the door 12 is in the restricted state and transition between the first and second states.

[0157] In the present embodiment, the second state is a state in which acceptance of a predetermined operation is restricted by restricting communication of communication unit 44. With such a configuration, safety can be ensured even when terminal device 300 is used to operate washing machine 100.

[0158] In this embodiment, washing machine 100 includes a power button 45a provided on the housing. When power button 45a is operated to shut off the power, control unit 52 switches locking mechanism 13 to a restricted state while maintaining the communication function of communication unit 44. With this configuration, door 12 enters a restricted state when power is shut off via operating unit 41b of washing machine 100. Therefore, door 12 remains locked during the power-off standby mode, ensuring safety even when terminal device 300 is operated.

[0159] In this embodiment, washing machine 100 includes an opening / closing detection switch 80 that senses the open / closed state of door 12. When power button 45a is operated to shut off the power, and if opening / closing detection switch 80 detects that door 12 (the sealing member) is open, control unit 52 does not accept the power shutoff operation and instead notifies the user of an abnormality. This configuration allows the user U to be prompted to close door 12 if the power shutoff operation is performed and door 12 of washing machine 100 is detected to be open.

[0160] In this embodiment, when the power button 45a is operated to turn on the power, the control unit 52 switches the lock mechanism 13 to the open state. With this configuration, when the power is turned on via the operation unit 41b of the washing machine 100, the lock mechanism 13 is switched to the open state, allowing the user U to open the door 12 and smoothly perform washing and drying operations.

[0161] In this embodiment, the predetermined operation is an operation to turn on the power supply from the outside via the communication unit 44. When the power button 45a is operated to turn on the power supply, the control unit 52 switches the locking mechanism 13 to the open state. If the predetermined operation is performed while the restriction unit 60 restricts acceptance of the predetermined operation, the control unit 52 does not switch the locking mechanism 13 to the open state. With this configuration, the user U can open the door 12 before the washing machine 100 and smoothly perform washing and drying operations. Furthermore, when operating the washing machine 100 using the terminal device 300, safety is ensured by maintaining the locking mechanism 13 in the restricted state.

[0162] In this embodiment, the predetermined operation is to turn on the power from the outside via the communication unit 44. If the predetermined operation is performed while the acceptance of the predetermined operation is restricted by the restriction unit 60, and if a predetermined condition related to the user U being within a certain distance from the washing machine 100 is satisfied, the control unit 52 switches the locking mechanism 13 to the open state. Even if the power is turned on by operating the terminal device 300, the user U can still confirm the surrounding conditions of the washing machine 100 if the user U is near the washing machine 100. With this configuration, if the user U operates the terminal device 300 near the washing machine 100, the door 12 can be opened, allowing washing and drying operations to proceed.

[0163] In this embodiment, when communication with the outside is set via communication unit 44 and power button 45a is operated to shut off the power, control unit 52 maintains the communication function of communication unit 44 and switches locking mechanism 13 to the restricted state. When communication with the outside is not set via communication unit 44 and power button 45a is operated to shut off the power, control unit 52 does not switch locking mechanism 13 to the restricted state and instead switches washing machine 100 to the power-off state. With this configuration, even when communication with the outside is not set via communication unit 44, door 12 can be opened during power standby, allowing for smooth washing and drying operations.

[0164] In this embodiment, washing machine 100 includes an operating unit (operating unit 41b, power button 45a, start / pause button 45b) provided on housing 11. Control unit 52 can transition to a special state in which it does not accept input to the operating unit but accepts external operations via communication unit 44. In this special state, when locking mechanism 13 is in the restricted state, control unit 52 accepts external operations via communication unit 44. This configuration allows operation of washing machine 100 to be prioritized by terminal device 300.

[0165] The embodiment and the modified examples have been described above, but the embodiment and the modified examples are not limited to the above examples.

[0166] According to at least one embodiment described above, the laundry processing machine of the embodiment includes a housing, a closing component, a locking mechanism, a communication unit, and a control unit. The housing has an opening into which laundry can be put. The closing component closes the opening in an openable and closable manner. The locking mechanism is capable of switching between an open state that allows the closing member to change from a closed state to an open state and a restricted state that restricts the closing member to the closed state. The communication unit is capable of communicating with the outside of the laundry processing machine. The control unit controls the locking mechanism and the communication unit. The restriction unit allows acceptance of prescribed operations from the outside via the communication unit when the locking mechanism is in the restricted state, and restricts acceptance of the prescribed operations via the communication unit when the locking mechanism is in the open state. According to such a configuration, improved convenience can be achieved.
