[0007] Hereinafter, a laundry processing machine according to an embodiment will be described with reference to the drawings. In the following description, components having the same or similar functions will be assigned the same reference numerals. Further, redundant descriptions of those components may be omitted. In this application, "based on XX" means "based on at least XX" and may include a case where the component is based on another element in addition to XX. Furthermore, "based on XX" is not limited to the direct use of XX, but may also include a case where the component is based on XX after calculation or processing. In this application, "XX or YY" is not limited to either XX or YY, but may include both XX and YY. This also applies when there are three or more optional elements. XX and YY are any element (e.g., any information).

[0008] In this application, "acquire" is not limited to actively acquiring information by sending a transmission request, but may also include passively receiving information transmitted from another device. "Acquire" may also include acquiring target information by performing calculations or processing on information obtained from an external source to generate the target information.

[0009] (Embodiment) <1. Overall configuration of the clothing processing system> 1 is a diagram showing the overall configuration of a clothing processing system 1 according to the first embodiment. The clothing processing system 1 includes, for example, a washing machine 100, a server 200, and a home appliance management application AP of a terminal device 300. The network NW described below may be, for example, the Internet, a cellular network, a Wi-Fi network, a Low Power Wide Area Network (LPWA), a Wide Area Network (WAN), a Local Area Network (LAN), or other public or dedicated lines, depending on the situation.

[0010] Washing machine 100 is an electrical appliance used in the residence of user U. Washing machine 100 is an example of a "clothing treatment machine." The term "clothing treatment machine" broadly refers to a device that performs some kind of treatment on clothes (for example, one or more of washing, drying, wrinkle removal, crease strengthening, deodorization, pollen removal, dust removal, or sterilization). A clothing treatment machine is, for example, a washing machine, but also includes a closet-type dry cleaner. In addition, in this application, the "washing machine" may be a washer-dryer with a drying function or a washing machine without a drying function. In the following, a drum-type washing machine will be described as an example of washing machine 100. However, washing machine 100 is not limited to a drum-type washing machine, and may be a vertical washing machine, a two-tub washing machine, or the like.

[0011] Washing machine 100 is connected to network NW via a wireless router WR and modem M installed in the residence of user U. Washing machine 100 can communicate with server 200 or terminal device 300 via network NW. Washing machine 100 may also be able to communicate directly with terminal device 300 via network NW or by using short-range wireless communication such as Bluetooth (registered trademark).

[0012] Server 200 is a management server that manages washing machine 100. Server 200 is configured by one or more server devices (for example, cloud servers). Server 200 can communicate with washing machine 100 or terminal device 300 via network NW. Server 200 may include an information processing unit that performs edge computing or fog computing, such as an information processing unit included in a router in network NW. Server 200 is not limited to a cloud server, and may be a computer in the residence of user U, or a home router (for example, a wireless router WR).

[0013] The terminal device 300 is an electronic device used by a user U. The terminal device 300 is, for example, a mobile terminal device such as a smartphone or a tablet terminal device. However, the terminal device 300 is not limited to a mobile terminal device and may be a personal computer or the like. The terminal device 300 has, for example, a display device 301, an input device 302, and a communication unit 303.

[0014] Display device 301 has display screen 301a capable of displaying various information. Input device 302 can accept input from user U. Input device 302 is, for example, a touch panel provided on top of display screen 301a of display device 301. Input device 302 may include a camera, a microphone, and the like provided in terminal device 300. Communication unit 303 is a communication module capable of wireless communication. Communication unit 303 is connected to network NW directly or via a wireless router WR and modem M. Communication unit 303 can communicate with washing machine 100 or server 200 via network NW. Note that communication unit 303 may be capable of communicating directly with washing machine 100 via network NW or by using short-range wireless communication such as Bluetooth, as described above.

[0015] An application program P is installed in the terminal device 300, and the terminal device 300 supports the functions described below. The application program P is, for example, an application program for managing the washing machine 100. Hereinafter, application software that is started by executing the application program P is referred to as a "home appliance management application AP." The application program P is an example of a "program."

[0016] <2. Overall configuration of the washing machine> Next, the overall configuration of the washing machine 100 will be described. 2 and 3 are front views showing washing machine 100. As shown in FIGS. 2 and 3, a door 12 that can be opened and closed is provided on the front surface of housing 11 of washing machine 100. FIG. 2 shows a state in which door 12 is closed relative to opening 11a of housing 11 (described later) (closed state). On the other hand, FIG. 3 shows a state in which door 12 is open relative to opening 11a of housing 11 (open state). Door 12 is an example of a "closing member."

[0017] The washing machine 100 is provided with a display / input unit 41. The display / input unit 41 includes a display unit 41a and an operation unit 41b. The display unit 41a is a display device that displays various information. The display unit 41a may be a liquid crystal display or an organic EL (Electro Luminescence) display having a display screen, or may be a lighting unit having a plurality of light-emitting diodes. The operation unit 41b is a functional unit that accepts operations by the user U regarding operation or reservation of the washing machine 100. The operation unit 41b may be a touch panel arranged overlaid on the display unit 41a, or may be physical buttons or dials provided on the housing 11.

[0018] The washing machine 100 is provided with a power button 45a, for example, as part of the operation unit 41b. The power button 45a can accept an operation by the user U to transition the washing machine 100 from a power-on state (power-on state) to a power-off state (power-off state), or to transition the washing machine 100 from a power-off state to a power-on state. In this application, the term "power-on state" refers to a state in which the main function of the washing machine 100 (e.g., a washing operation) can be executed. On the other hand, the term "power-off state" refers to a state in which all functions, including the communication function of the communication unit 44, are stopped.

[0019] In this embodiment, when the communication unit 44 described later is set to communicate with the outside (for example, when set to online mode), the power button 45a can accept an operation by the user U to transition the washing machine 100 from a power-on state to a power-saving state (a standby state for remote operation). The power button 45a can also accept an operation by the user U to transition the washing machine 100 from a power-saving state to a power-on state. In the power-saving state, the main function of the washing machine 100 (for example, a washing operation) cannot be executed, but some functions such as the communication function of the communication unit 44 are maintained. The power button 45a is an example of a "power operation unit."

[0020] Further, for example, a start / pause button 45b is provided as a part of the operation unit 41b in the washing machine 100. The start / pause button 45b can accept an operation by a user U to start or pause the operation of the washing machine 100.

[0021] 3, a protrusion 71 is provided on the back surface of door 12. Furthermore, housing 11 is provided with locking mechanism 13 at a position corresponding to protrusion 71. When door 12 is in the closed state, if protrusion 71 and locking mechanism 13 engage with each other, door 12 is restricted to the closed state.

[0022] 4 is a cross-sectional view showing washing machine 100. Washing machine 100 has, for example, housing 11, door 12, locking mechanism 13, water tub 14, drum 15, motor 16, water supply valve 21, water supply case 22, drain pipe 25, drain valve 26, main duct 31, front duct 32, fan casing 33, blower 34, rear duct 35, heat pump 36, display / input unit 41, vibration sensor unit 42, heat pump control unit 43, communication unit 44, and main control unit 50.

[0023] Housing 11 is a hollow housing. A through-hole-like opening 11a is formed in the front panel of housing 11. A user U using washing machine 100 can put clothes, which are to be washed, into housing 11 through opening 11a. Door 12 is attached to the front panel of housing 11. Door 12 closes opening 11a in an openable and closable manner. Door 12 is an example of a "closing member." In the case of a vertical washing machine, a cover member that closes opening 11a at the top of housing 11 in an openable and closable manner is an example of a "closing member."

[0024] 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 change from a closed state to an open 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 freely open and close the door 12, for example, manually. 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.

[0025] A water tub 14 is fixed inside housing 11. A drum 15, which is a rotating tub, is housed inside water tub 14. A motor 16 that rotates drum 15 is fixed to the rear panel of water tub 14.

[0026] A water supply valve 21 is fixed inside the housing 11. The inlet of the water supply valve 21 is connected to a water faucet. The water supply valve 21 is switched between an open state and a closed state depending on the rotation amount of a motor possessed by the water supply valve 21. The outlet of the water supply valve 21 is connected to a water supply case 22. The water supply case 22 has a cylindrical water supply port 22a. The water supply port 22a is inserted inside the water tank 14. Tap water injected from the water supply valve 21 into the water supply case 22 is injected into the water tank 14 from the water supply port 22a.

[0027] The upper end of a drain pipe 25 is connected to the water tank 14. A drain valve 26 is provided on the drain pipe 25. The drain valve 26 is switched between an open state and a closed state depending on the rotation amount of a motor provided in the drain valve 26.

[0028] 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 water tank 14. A fan casing 33 is fixed to the rear end of the main duct 31. A blower 34 is disposed in the fan casing 33. The lower end of a rear duct 35 is connected to the exhaust port of the fan casing 33. The upper end of the rear duct 35 is connected to the water tank 14.

[0029] A heat pump 36 is provided inside the housing 11. The heat pump 36 has a compressor 36a and is a heating device provided in the main duct 31. The heat pump 36 heats the dry air passing through the main duct 31. Note that the washing machine 100 may have a heater that heats the dry air instead of the heat pump 36.

[0030] The display / input unit 41 is provided in the housing 11. The display / input unit 41 includes the above-mentioned display section 41a and operation section 41b.

[0031] Vibration sensor unit 42 is a sensor unit that is provided in water tub 14 and detects vibrations of water tub 14. Vibration sensor unit 42 detects, for example, acceleration acting on water tub 14. Heat pump control unit 43 is a control unit that is provided in association with heat pump 36 and controls heat pump 36. Heat pump control unit 43 controls the operation of heat pump 36 (for example, the operation of compressor 36a) based on the detection result of the temperature of the drying air passing through main duct 31.

[0032] Communication unit 44 is capable of communicating with the outside of washing machine 100. For example, communication unit 44 is a communication module (for example, a network connection adapter) for communicating with external server 200. Communication unit 44 transmits and receives information about washing machine 100 to and from server 200. Communication unit 44 is connected to network NW via, for example, 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.

[0033] Communication unit 44 transmits and receives predetermined information to and from server 200. Information transmitted from communication unit 44 to server 200 includes the status, operation history, and abnormality information of washing machine 100. On the other hand, information transmitted from server 200 to communication unit 44 is, for example, information related to an operation performed by user U using terminal device 300. For example, information transmitted from server 200 to communication unit 44 includes a setting for a scheduled operation of washing machine 100, an operation for turning on washing machine 100, or an operation for starting operation of washing machine 100.

[0034] In the present application, "an operation in a power-on mode" broadly means an operation that appears to the user U as having been powered on. For example, in the present application, "an operation in a power-on mode" is not limited to an operation that transitions the washing machine 100 from a power-off state (power-off state) to a power-on state (power-on state), but may also include an operation that returns the washing machine 100 from a power-saving state (standby state) to a normal state (normal power-on state). From another perspective, in the present application, "an operation in a power-on mode" means supplying power to at least some of the functions of the washing machine 100 that are powered off in the power-saving state (standby state) (for example, a function for executing a washing operation).

[0035] Similarly, in the present application, "an operation in a manner to turn off the power" broadly means an operation that appears to have turned off the power from the perspective of user U. For example, in the present application, "an operation in a manner to turn off the power" is not limited to an operation that transitions washing machine 100 from a power-on state (power-on state) to a power-off state (power-off state), but may also include an operation that transitions from a normal state (normal power-on state) to a power-saving state (standby state). From another perspective, in the present application, "an operation in a manner to turn off the power" means stopping the power supply to at least some of the functions of washing machine 100 that are turned off in the power-saving state (standby state) (for example, a function for performing a washing operation).

[0036] Communication unit 44 is a component that can control power supply (can transition to a power-off state) independently of the power supply for the main functions of washing machine 100 (for example, the power supply for main microcomputer 52). For example, washing machine 100 can be set to a mode (offline mode) in which no communication with server 200 is performed, based on an operation by user U. When washing machine 100 is set to the offline mode, main microcomputer 52 transmits a signal to communication unit 44 to transition the power supply of communication unit 44 to the power-off state. When communication unit 44 receives the signal, it transitions the power supply of communication unit 44 to the power-off state. As a result, the power supply of communication unit 44 is turned off while the power supply for the main functions of washing machine 100 remains on.

[0037] Main control unit 50 is a control unit that performs overall control of washing machine 100. Main control unit 50 includes circuit board 51 and main microcomputer 52. Main microcomputer 52 is mounted on circuit board 51. Main microcomputer 52 performs overall control of washing machine 100. Main microcomputer 52 controls lock mechanism 13, motor 16, water supply valve 21, drain valve 26, blower 34, display / input unit 41, heat pump control unit 43, communication unit 44, etc.

[0038] <3. Locking mechanism> Next, the locking mechanism 13 will be described. 5 and 6 are plan views schematically showing the locking mechanism 13. Fig. 5 shows the unlocked state, and Fig. 6 shows the locked state.

[0039] As shown in Figures 5 and 6, the locking mechanism 13 includes, for example, an open / close detection switch 80, an engagement portion 81, a solenoid 82, an operator 83, a spring 84, a locking claw 85, a locking claw movable mechanism 86, a locking detection switch 87, and a spring 88.

[0040] The open / close detection switch 80 is a detection unit that detects the open / closed state of the door 12. For example, when the door 12 is closed, the protrusion 80a of the open / close detection switch 80 abuts against the door 12, causing the open / close detection switch 80 to transition to an ON state (see FIG. 6). On the other hand, when the door 12 is opened, the protrusion 80a of the open / close detection switch 80 and the door 12 separate, causing the open / close detection switch 80 to transition to an OFF state (see FIG. 5). The open / close detection switch 80 changes state depending on the open / closed state of the door 12, thereby enabling it to detect the open / closed state of the door 12. The open / close detection switch 80 may be provided as an external component of the locking mechanism 13.

[0041] The engaging portion 81 engages with the protrusion 71 (see Figure 3) of the door 12 in the closed state. A locking claw 85 is provided inside the engaging portion 81. The locking claw 85 is biased in the direction of arrow Q1 by a spring 88. When the locking mechanism 13 is in the unlocked state (see Figure 5), the locking claw 85 is in a position disengaged from the engaging portion 81. The locking claw 85 moves up and down in conjunction with the movement of the operator 83 by a locking claw moving mechanism 86.

[0042] Movable piece 82a of solenoid 82 is connected to operator 83 and moves operator 83 in the direction of arrow P1. Operator 83 is equipped with a knock cam mechanism. The knock cam mechanism is a mechanism that alternates between a first position L1 and a second position L2 as the position to which operator 83 returns after a force is applied to it. Operator 83 is biased by a spring 84 in the direction of arrow P2.

[0043] When the locking mechanism 13 is in the unlocked state (see FIG. 5), the tension of the spring 88 keeps the locking claw 85 in a position disengaged from the engaging portion 81. From this state, the movable piece 82a of the solenoid 82 moves the operator 83 in the direction of arrow P1, and when the operator 83 moves to the second position L2, the locking claw moving mechanism 86 moves the locking claw 85 in the direction of arrow Q2, as shown in FIG. 6. This causes the locking claw 85 to protrude into the engaging portion 81, and the locking mechanism 13 transitions to the locked state.

[0044] On the other hand, when the driving of the solenoid 82 is stopped, the tension of the spring 84 causes the operator 83 to return in the direction of arrow P2. At this time, the knock cam mechanism causes the position to which the operator 83 returns to alternate between a first position L1 and a second position L2 each time the solenoid 82 is driven. When the locking mechanism 13 transitions from the unlocked state (see FIG. 5) to the locked state (see FIG. 6), the position to which the operator 83 returns is restricted 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 point, the locking mechanism 13 is maintained in the locked state.

[0045] When the movable piece 82a of the solenoid 82 moves the operator 83 in the direction of arrow P1 from the locked state shown in FIG. 6 and the driving of the solenoid 82 is stopped, the tension of the spring 84 causes the operator 83 to return in the direction of arrow P2. When transitioning from the locked state (see FIG. 6) to the unlocked state (see FIG. 5), the operator 83 returns to the first position L1. In this case, as shown in FIG. 5, the locking claw 85 is disengaged from the engaging portion 81, and the locking mechanism 13 transitions to the unlocked state. When the locking mechanism 13 transitions from the locked state (see FIG. 6) to the unlocked state (see FIG. 5), the position to which the operator 83 returns is restricted to the first position L1. In this case, the locking claw 85 remains disengaged from the engaging portion 81, and the locking mechanism 13 remains in the unlocked state even if the power supply to the locking mechanism 13 (for example, the power supply to the solenoid 82) is stopped at this point.

[0046] In this way, each time the solenoid 82 is driven, the locking mechanism 13 alternates between a locked state in which the locking claw 85 protrudes into the engaging portion 81 and an unlocked state in which the locking claw 85 is disengaged from the engaging portion 81. The locked state or the unlocked state is maintained even after the power to the solenoid 82 is cut off.

[0047] The lock detection switch 87 transitions between an ON state and an OFF state depending on the state of the locking mechanism 13 (for example, the position of the operator 83). As shown in FIG. 5, when the locking mechanism 13 is in an unlocked state, the operator 83 is in a first position L1, and at this time the lock detection switch 87 is in an OFF state. On the other hand, when the locking mechanism 13 is in a locked state, the operator 83 is in a second position L2, and the lock detection switch 87 is in an ON state. As a result, it is possible to determine whether the locking mechanism 13 is in a locked state or an unlocked state based on the state of the lock detection switch 87.

[0048] <4. Display and input systems> Next, the display and input systems will be described. In this embodiment, a display / input unit 41 is provided in 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.

[0049] 7 is a diagram showing a display and input system arranged on the main body of washing machine 100. As shown in FIG. 7, a plurality of operation buttons B are arranged on display / input unit 41 as a plurality of operation sections. For example, as part of the plurality of operation buttons B, display / input unit 41 is arranged with a bath water setting button B1, a warm water setting button B2, a detergent amount setting button B3, a fabric softener amount setting button B4, and a timer setting button B5. Also, as part of the plurality of operation buttons B, display / input unit 41 is arranged with a wash stroke setting button B6, a rinse stroke setting button B7, a spin stroke setting button B8, a drying stroke setting button B9, a wash operation selection button B10, a wash / dry operation selection button B11, and a drying operation selection button B12.

[0050] Furthermore, display / input unit 41 has a remote standby button B13 arranged as part of operation buttons B. Remote standby button B13 is a button for transitioning washing machine 100 to a special state (special standby state) for remote operation. The special state is a state in which input from user U to operation units (operation unit 41b, power button 45a, and start / pause button 45b) provided on housing 11 of washing machine 100 is not accepted, but an operation from outside via communication unit 44 is accepted.

[0051] The display / input unit 41 is also 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 reservation setting time, the end time of washing and drying, etc. The display area D also displays various warnings.

[0052] Furthermore, the washing machine 100 can be operated using the terminal device 300 by communicating with the terminal device 300 via the server 200, for example. Fig. 8 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 screen 301a shown in Fig. 8 is displayed. Note that the display of the operation unit described below and the reception of the operation of the user U on the displayed operation unit are executed by the home appliance management application AP.

[0053] 8, the screen of terminal device 300 displays wash course setting button 311a, reservation setting button 311b, washing / fabric softener setting button 311c, power button 311d, and start / pause button 311e as operation units for accepting operations by user U. Wash course setting button 311a, reservation setting button 311b, and washing / fabric softener setting button 311c have a hierarchical structure, and pressing each of buttons 311a to 311c displays a more detailed setting screen.

[0054] Power button 311d is a button that can accept the same operation as power button 45a of washing machine 100. For example, when the communication unit 44 is set to communicate with the outside (for example, when the wireless router WR is set to be used), power button 311d can accept an operation by user U to transition washing machine 100 from a power-on state to a power-saving state (standby state for remote operation). Furthermore, power button 311d can accept an operation by user U to transition washing machine 100 from a power-saving state (standby state) to a power-on state.

[0055] Start / pause button 311e is a button that can accept the same operation as start / pause button 45b. For example, start / pause button 311e and start / pause button 45b can accept an operation by user U to start or pause the operation of washing machine 100.

[0056] In this way, in this embodiment, the power on / off operation and the start / pause operation of the washing machine 100 can be performed using the power button 45a and the start / pause button 45b on the washing machine 100 main body, as well as the power button 311d and the start / pause button 311e on the terminal device 300.

[0057] <5. Control System> Next, the control system will be described. FIG. 9 is a block diagram showing the configuration of a control system of washing machine 100. As shown in FIG. 9, control unit 52 is connected to communication unit 44. Communication unit 44 transmits transmission data TXD from control unit 52 to terminal device 300. Communication unit 44 also transmits reception data RXD received from external terminal device 300 to control unit 52. Furthermore, communication unit 44 can send a power saving state release signal Wake_UP to control unit 52. When control unit 52 receives power saving state release signal Wake_UP, it transitions from the power saving state (standby state for remote control) to the normal state.

[0058] The control unit 52 is also connected to the display / input unit 41. The display / input unit 41 includes a display unit 41a and an operation unit 41b. An operation input signal is sent from the operation unit 41b to the control unit 52. The control unit 52 also sends a display signal to the display unit 41a.

[0059] In addition, an operation signal related to power-on and power-off is sent from the power button 45a to the control unit 52. In addition, an operation signal related to start and pause is sent from the start / pause button 45b to the control unit 52.

[0060] The control unit 52 is also connected to the open / close detection switch 80, lock detection switch 87, and solenoid 82 of the lock mechanism 13. The control unit 52 determines whether the door 12 is open or closed based on the state of the open / close detection switch 80. The control unit 52 determines whether the lock mechanism 13 is in an unlocked state or a locked state based on the state of the lock detection switch 87. The control unit 52 drives the solenoid 82 to transition the lock mechanism 13 to the locked state or the unlocked state.

[0061] In this embodiment, the lock detection switch 87 is disposed in the power 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 explained later.

[0062] Control unit 52 also controls washing / drying processing unit 95. Washing / drying processing unit 95 controls motor 16, heat pump 36, water supply valve 21, drain valve 26, etc. in accordance with the operation mode and reservation settings, etc., to perform various processes when performing washing operation and drying operation.

[0063] Control unit 52 also controls power supply unit 90. Power supply unit 90 includes a main power supply unit 91 and a communication power supply unit 92. Main power supply unit 91 generates power for each unit required for the operation of the main functions of washing machine 100 from commercial power supply 96. Communication power supply unit 92 generates power required for communication unit 44. Communication power supply unit 92 can be set to turn on / off independently of main power supply unit 91. Communication power supply unit 92 can supply power to communication unit 44 via lock detection switch 87, for example. Communication power supply unit 92 can also supply power to functional units related to communication in control unit 52 (main microcomputer 52). A battery may be used as communication power supply unit 92.

[0064] In the power saving state (standby state for remote control) of washing machine 100, power supply to each part of washing machine 100 (motor 16, heat pump 36, etc.) is stopped, and power supply to display unit 41a and operation unit 41b is also stopped. Furthermore, in the power saving state (standby state for remote control) of washing machine 100, power supply to related functions such as a clock oscillation circuit used to control main microcomputer 52 is also stopped.

[0065] When the washing machine 100 is in the power-on state, power can be supplied to each unit of the washing machine 100, and power is also supplied to the display unit 41a and the operation unit 41b. Also, when the washing machine 100 is in the power-on state, the clock oscillation circuit generates a clock at a normal frequency.

[0066] Furthermore, the control unit 52 performs processing to realize the following functions. (1) When power button 45a of washing machine 100 is operated to turn off the power, control unit 52 transitions lock mechanism 13 to the locked state and maintains the communication function of communication unit 44. For example, when communication unit 44 is set to communicate with the outside (for example, when online mode is set), and when power button 45a of washing machine 100 is operated to turn off the power, control unit 52 drives solenoid 82 to transition lock mechanism 13 to the locked state and transitions washing machine 100 from the power-on state to the power-saving state. On the other hand, when communication unit 44 is not set to communicate with the outside (for example, when offline mode is set), and when power button 45a of washing machine 100 is operated to turn off the power, control unit 52 transitions washing machine 100 from the power-on state to the power-off state while maintaining lock mechanism 13 in the unlocked state.

[0067] (2) When an operation to turn off the power is performed on power button 45a of washing machine 100 and open / close detection switch 80 detects that door 12 is open, control unit 52 does not accept the operation to turn off the power and notifies the user of an abnormality. For example, as an example of notifying the user of an abnormality, control unit 52 causes display unit 41a to display a warning indicating that door 12 is open, or causes a speaker provided in washing machine 100 (or a voice dialogue device provided separately) to output a voice warning indicating that door 12 is open.

[0068] (3) When the power button 45a of the washing machine 100 is operated to turn on the power, the control unit 52 transitions the lock mechanism 13 from the locked state to the unlocked state.

[0069] (4) When locking mechanism 13 is in the locked state and power button 45a of washing machine 100 is operated to turn on the power, control unit 52 transitions locking mechanism 13 from the locked state to the unlocked state. On the other hand, when locking mechanism 13 is in the locked state and power button 45a of washing machine 100 is operated to turn on the power while locking mechanism 13 is in the special standby state, control unit 52 does not accept the operation and maintains locking mechanism 13 in the locked state.

[0070] (5) When locking mechanism 13 is in the locked state and power button 45a of washing machine 100 is operated to turn on the power, control unit 52 transitions locking mechanism 13 from the locked state to the unlocked state. On the other hand, when the predetermined operation (for example, an operation to transition washing machine 100 to the power-on state using terminal device 300) is performed from the outside via communication unit 44 in a state in which acceptance of the predetermined operation is restricted by restriction unit 60 (described later), control unit 52 maintains locking mechanism 13 in the locked state.

[0071] (6) When a predetermined operation (e.g., an operation to transition the washing machine 100 to a power-on state using the terminal device 300) is performed from the outside via the communication unit 44 in a state in which acceptance of the predetermined operation is restricted by the restriction unit 60 (described later), and a predetermined condition related to the user U being present within a predetermined distance (e.g., within a certain distance) from the washing machine 100 is satisfied, the control unit 52 may transition the locking mechanism 13 from the locked state to the unlocked state. The predetermined condition related to the user U being present within the predetermined distance from the washing machine 100 is satisfied, for example, when communication with the terminal device 300 is completed within the user U's residence using the wireless router WR, or when location information of the terminal device 300 (e.g., location information using the Global Navigation Satellite System (GNSS)) corresponds to the user U's home. The predetermined condition related to the user U being present within the predetermined distance from the washing machine 100 may also be satisfied when the user U is detected by a human presence sensor provided in the washing machine 100 or another home appliance, or when use of another home appliance located in the same residence is detected in a recent time period within a predetermined time period.

[0072] (7) Control unit 52 can transition to a special state (special standby state) in which it does not accept input to the operation units (operation unit 41b, power button 45a, or start / pause button 45b) of washing machine 100, but accepts external operations via communication unit 44. In the special state, when locking mechanism 13 is in the locked state, it accepts external operations from terminal device 300 via communication unit 44.

[0073] <6. Restrictions> Next, the restriction unit 60 will be described. 9, 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 realizes an example of the limiting unit 60.

[0074] Restriction unit 60 allows a predetermined operation to be received from outside via communication unit 44 when locking mechanism 13 is in a locked state, and restricts the reception of a predetermined operation via communication unit 44 when locking mechanism 13 is in an unlocked state. For example, restriction unit 60 restricts the reception of a predetermined operation via communication unit 44 in conjunction with locking mechanism 13 changing from a locked state to an unlocked state. Here, the predetermined operation is, for example, an operation to transition washing machine 100 to a power-on state using terminal device 300, or an operation to start operation of washing machine 100 using terminal device 300.

[0075] In this 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 operate even when power is not supplied from the main power supply unit 91 (the above-described power saving state).

[0076] When the locking mechanism 13 is in the locked state, the lock detection switch 87 is turned on. Therefore, the power supply Vdd is supplied to the communication unit 44 from the communication power supply unit 92. This puts the communication unit 44 into an operable state, and the communication unit 44 can receive an operation signal input from the terminal device 300 via the communication unit 44.

[0077] On the other hand, when the locking mechanism 13 transitions from the locked state to the unlocked state, the lock detection switch 87 is turned off. As a result, power is no longer supplied to the communication unit 44. This prevents the communication unit 44 from operating, and restricts the reception of operation signals input from the terminal device 300 via the communication unit 44.

[0078] As described above, the restriction unit 60 includes a lock detection switch 87 (switching unit) whose physical or electrical state changes depending on whether the lock mechanism 13 is in an unlocked state or a locked state. The communication unit 44 transitions between a first state that allows acceptance of the predetermined operation and a second state that restricts acceptance of the predetermined operation, depending on the state of the lock detection switch 87. The lock detection switch 87 (switching unit) may be any component that changes at least one of its physical state and electrical state depending on whether the lock mechanism 13 is in an unlocked state or a locked state. The switching unit may also be a component that is provided outside the lock mechanism 13.

[0079] In the present embodiment, the second state is a state in which the predetermined operation is restricted by restricting communication by the communication unit 44. In the present embodiment, the second state is a state in which communication by the communication unit 44 is restricted by cutting off power supply to the communication unit 44.

[0080] The communication power supply unit 92 can be controlled independently of the main power supply unit 91, and can be operated even in the above-mentioned power saving state (standby state for remote control). The locking mechanism 13 is maintained in the locked state or the unlocked state even after the power supply to the locking mechanism 13 is stopped. Therefore, the restriction unit 60 can control the operation of the communication unit 44 even in the above-mentioned power saving state (standby state for remote control).

[0081] 7. Control Flow Next, the control flow of this embodiment will be described. 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 pausing the operation of the washing machine 100 can be performed using the power button 45a and start / pause button 45b of the washing machine 100, and can also be performed using the power button 311d and start / pause button 311e of the terminal device 300.

[0082] 10 is a flowchart showing the flow of control when an operation is performed using terminal device 300 in this embodiment. When washing machine 100 receives the predetermined operation from terminal device 300, washing machine 100 is in a power saving state (standby state for remote operation) (step S1). In the standby state, main power supply unit 91 is turned off.

[0083] A user U who uses the washing machine 100 operates the power button 311d of the terminal device 300 to transition the washing machine 100 to a power-on state (step S2). When the power button 311d of the terminal device 300 is operated, an operation signal for executing power-on (an operation signal for transitioning the washing machine 100 to a power-on state) is transmitted from the terminal device 300 to the washing machine 100 via the server 200.

[0084] When power button 311d of terminal device 300 is operated to instruct power-on, the process branches depending on whether locking mechanism 13 is in the locked state or not (step S3). That is, if locking mechanism 13 of washing machine 100 is in the locked state (step S3: YES), lock detection switch 87 is in the on state, and power is supplied from communication power supply unit 92 to communication unit 44. On the other hand, if locking mechanism 13 of washing machine 100 is in the unlocked state (step S3: NO), lock detection switch 87 is in the off state, and power is not supplied from communication power supply unit 92 to communication unit 44.

[0085] Therefore, if lock mechanism 13 is in the locked state (step S3: YES), communication unit 44 can receive a power-on operation signal, and an operation to transition washing machine 100 to the power-on state is performed (step S4). In this operation, for example, communication unit 44 transmits a power-saving state release signal Wake_UP to control unit 52. Control unit 52 transitions from the power-saving state to the normal state in response to this power-saving state release signal Wake_UP. Then, communication unit 44 transmits a power-on operation signal to control unit 52, transitioning washing machine 100 to the power-on state. When the power-on operation is completed, main power supply unit 91 is activated, and power is supplied to each unit.

[0086] On the other hand, if the lock mechanism 13 is in an unlocked state (step S3: NO), the communication unit 44 cannot receive the power-on operation signal (step S5), and the process ends.

[0087] Next, the user U who uses the washing machine 100 operates the start / pause button 311e of the terminal device 300 to start the operation of the washing machine 100 (step S6). When the start / pause button 311e of the terminal device 300 is operated, an operation signal for starting the operation is transmitted from the terminal device 300 to the washing machine 100 via the server 200.

[0088] When start / pause button 311e of terminal device 300 is operated to instruct the start of operation, the process branches depending on whether locking mechanism 13 is in the locked state or not (step S7). For example, if locking mechanism 13 of washing machine 100 is in the locked state (step S7: YES), lock detection switch 87 is in the on state, and power is supplied from communication power supply unit 92 to communication unit 44. On the other hand, if locking mechanism 13 of washing machine 100 is in the unlocked state (step S7: NO), lock detection switch 87 is in the off state, and power is not supplied from communication power supply unit 92 to communication unit 44.

[0089] Therefore, if lock mechanism 13 is in the locked state (step S7: YES), communication unit 44 can receive an operation signal to start operation, and washing machine 100 starts operation (step S9).

[0090] 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 to start operation in step S5 (step S8), and the process ends.

[0091] As described above, in this embodiment, when lock mechanism 13 is in the locked state (open state), power supply to communication unit 44 is stopped, and communication unit 44 cannot receive an external operation signal. This ensures safety even in an environment where user U using washing machine 100 cannot check the surroundings of washing machine 100.

[0092] Next, the process of the control unit 52 when the power is turned on will be described. FIG. 11 is a flowchart showing the flow of processing by the control unit 52 when a power-on operation is performed.

[0093] The washing machine 100 is in a power saving state (standby state for remote operation) (step S101) when accepting the predetermined operation from the terminal device 300. In the standby state, the main power supply unit 91 is turned off.

[0094] Control unit 52 determines whether or not a power-on operation has been performed (step S102). Here, the power-on operation may be performed by power button 45a on washing machine 100 main body or by power button 311d on terminal device 300.

[0095] When control unit 52 determines that a power-on operation has been performed, it determines whether the power-on operation has been performed using power button 45a of washing machine 100 or whether the power-on operation has been performed remotely using operation button 311d of terminal device 300 (step S103). If the power-on operation has been performed using power button 45a of washing machine 100 (step S103: YES), control unit 52 transitions lock mechanism 13 to the unlocked state (step S106) and transitions washing machine 100 to the power-on state (step S107).

[0096] If the power-on operation is performed using power button 311d of terminal device 300 (step S103: NO), control unit 52 determines whether user U is present within a predetermined distance from washing machine 100 (step S104). If user U is present within the predetermined distance (step S104: YES), control unit 52 transitions lock mechanism 13 to the unlocked state (step S106) and transitions washing machine 100 to the power-on state (step S107).

[0097] On the other hand, if the user U is not present within the predetermined distance (step S104: NO), the control unit 52 maintains the locking mechanism 13 in the locked state (step S105) and transitions the washing machine 100 to the power-on state (step S107).

[0098] In this way, when the power-on operation is performed by power button 45a of washing machine 100 main body (step S102, step S103: YES), control unit 52 transitions lock mechanism 13 to the unlocked state (step S106). As a result, after performing the power-on operation, user U can open door 12 and immediately perform washing and drying operations.

[0099] Furthermore, if the power-on operation is performed using the power button 311d of the terminal device 300 (step S103: No), safety can be ensured by maintaining the lock mechanism 13 in the locked state (step S105).

[0100] Even if the power-on operation is performed by operating terminal device 300, if user U is near washing machine 100, user U can check the situation around washing machine 100. Therefore, even if the power-on operation is performed by operating terminal device 300, if user U is near washing machine 100 (step S104: Yes), control unit 52 keeps locking mechanism 13 in the unlocked state (step S105).

[0101] Next, the process of the control unit 52 when a power-off operation is performed will be described. FIG. 12 is a flowchart showing the flow of processing by the control unit 52 when a power-off operation is performed.

[0102] The control unit 52 determines whether or not a power-off operation has been performed (step S201).

[0103] When the control unit 52 determines that a power-off operation has been performed (step S201: Yes), it determines whether the communication setting is on or not (i.e., whether the mode is online or offline) (step S202). If the communication state is off (if the mode is offline) (step S202: NO), the control unit 52 performs a power-off process and transitions the washing machine 100 to a power-off state (step S208).

[0104] If the communication state is on (if in online mode) (step S202: YES), control unit 52 determines whether the power-off operation is performed using power button 45a of washing machine 100 or by remote operation using operation button 311d of terminal device 300 (step S203). If the power-off operation is performed by remote operation using operation button 311d of terminal device 300 (step S203: NO), control unit 52 maintains lock mechanism 13 in the locked state (step S206), performs power-off processing, and transitions washing machine 100 to a power-saving state (a standby state for remote operation) (step S207).

[0105] If the power-off operation is performed on the power button 45a of the washing machine 100 main body (step S203: YES), the control unit 52 determines whether the door 12 is open or not based on the state of the open / close detection switch 80 (step S204).

[0106] When the control unit 52 determines that the door 12 is open (step S204: YES), it displays an abnormality on the display unit 41a indicating that the door 12 is open, and notifies the user U (step S205).

[0107] When the control unit 52 determines that the door 12 is in the closed state (step S204: NO), it transitions the locking mechanism 13 to the locked state (step S206), performs a power-off process, and transitions the washing machine 100 to the power-saving state (standby state for remote operation) (step S207).

[0108] In this way, if door 12 is open when the power-off operation is performed on power button 45a of washing machine 100 (step S204: YES), a message indicating that door 12 is open is displayed on display unit 41a (step S205). Seeing this message, user U is prompted to close door 12.

[0109] Furthermore, when the power-off operation is performed using the power button 45a of the washing machine 100 (step S203: YES), the locking mechanism 13 transitions to the locked state (step S206). Furthermore, when the power-off operation is performed using the operation button 311d of the terminal device 300 (step S203: NO), the locking state is maintained. As a result, in the power-off standby state, the locking mechanism 13 is in the locked state, ensuring safety.

[0110] When the communication setting is off (offline mode) (step S202: Yes), the user U does not remotely operate the washing machine 100, and therefore the locking mechanism 13 is not set to the locked state.

[0111] 13 is an example of a notification that is displayed when the power is turned off in step S205 while the door 12 is open. If the power is turned off while the door 12 is open, a notification D1 that urges the user to close the door 12 is displayed in the display area D of the display section 41a of the display / input unit 41, as shown in FIG.

[0112] If door 12 needs to be opened while it is locked, locking mechanism 13 can be transitioned from the locked state to the unlocked state by, for example, a specific operation on operation unit 41b. In this case, as shown in FIG. 14 , notification D2 prompting confirmation that door 12 should be opened is displayed in display area D of display unit 41a of display / input unit 41. Considering the risk of children playing with the device, a special operation method may be used to unlock the device, such as pressing multiple buttons simultaneously or setting a number of button presses. The specific operation on operation unit 41b is an example of an "operation different from the operation for turning on the power." Notification D2 prompting confirmation that door 12 should be opened may 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 may transmit an operation signal permitting opening of door 12 from terminal device 300 to washing machine 100 via server 200.

[0113] <8. Remote Standby> Depending on the usage pattern of user U, it may be considered that operation of washing machine 100 is given priority via terminal device 300. Therefore, in this embodiment, washing machine 100 is transitioned to a special state in which input from terminal device 300 via communication unit 44 is accepted without accepting input from the washing machine main body.

[0114] 7, a remote standby button B13 is provided on the display / input unit 41. The remote standby button B13 enables transition to a special state (special standby state). In the special state, when the locking mechanism 13 is in the locked state, an external operation signal is received from the terminal device 300 via the communication unit 44.

[0115] <8. Variations>

[0116] In the above-described configuration, the restriction unit 60 supplies or cuts off power to the communication unit 44 depending on the state of the lock detection switch 87, thereby transitioning the communication unit 44 between a first state in which acceptance of a predetermined operation is permitted and a second state in which acceptance of the predetermined operation is restricted. However, the configuration is not limited to this. For example, power may be constantly supplied to the communication unit 44 even in a standby state, and data communication by the communication unit 44 may be enabled or restricted depending on the state of the lock detection switch 87, thereby transitioning the communication unit 44 between the first state in which acceptance of a predetermined operation is permitted and the second state in which acceptance of the predetermined operation is restricted. Furthermore, the communication line between the communication unit 44 and the control unit 52 may be connected or cut off depending on the state of the lock detection switch 87. For example, in the second state, communication by the communication unit 44 may be restricted by restricting communication between the control unit 52 and the communication unit 44 (e.g., by preventing the control unit 52 from accepting signals from the communication unit 44) instead of cutting off the power supply to the communication unit 44.

[0117] <9. Advantages> 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 through which clothes can be inserted. The door 12 closes the opening 11a in an openable and closable manner. The locking mechanism 13 can transition 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 the closed state. The communication unit 44 can communicate 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 a predetermined operation to be received from the outside via the communication unit 44 when the locking mechanism 13 is in the restricted state, and restricts the reception of the predetermined operation via the communication unit 44 when the locking mechanism 13 changes from the restricted state to the open state. With this configuration, when the locking mechanism 13 is in the open state, the reception of the predetermined 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, the user U can perform predetermined operations from outside while ensuring safety, thereby improving the convenience of the washing machine 100.

[0118] In this embodiment, in conjunction with the transition of lock mechanism 13 from the restricted state to the open state, restriction unit 60 restricts the acceptance of a predetermined operation via communication unit 44. With this configuration, washing machine 100 can more reliably restrict the acceptance of a predetermined operation from outside via communication unit 44 when lock mechanism 13 is in the open state.

[0119] In this embodiment, restriction unit 60 includes lock detection switch 87 (switching unit) whose physical or electrical state changes depending on whether lock mechanism 13 is in the open state or the restricted state. Restriction unit 60 transitions between a first state that allows acceptance of a predetermined operation and a second state that restricts acceptance of the predetermined operation based on the state of lock detection switch 87. With this configuration, even when washing machine 100 is in a standby state with the power turned off, it can reliably determine whether door 12 is in the restricted state and transition between the first state and the second state.

[0120] In the present embodiment, the second state is a state in which acceptance of a predetermined operation is restricted by restricting communication by communication unit 44. With this configuration, safety can be ensured even when washing machine 100 is operated using terminal device 300.

[0121] In this embodiment, washing machine 100 includes power button 45a provided on the housing. When power button 45a is operated to turn off the power, control unit 52 transitions lock mechanism 13 to the restricted state and maintains the communication function of communication unit 44. With this configuration, when an operation to turn off the power is performed on operation unit 41b of washing machine 100, door 12 enters the restricted state. Therefore, while in the power-off standby state, door 12 is in the locked state, and safety can be ensured even if terminal device 300 is operated.

[0122] In this embodiment, washing machine 100 includes open / closed detection switch 80 that detects the open / closed state of door 12. When an operation to turn off the power is performed on power button 45a and open / closed detection switch 80 detects that door 12 (closing member) is open, control unit 52 does not accept the operation to turn off the power and notifies of an abnormality. With this configuration, when an operation to turn off the power is performed and door 12 of washing machine 100 is detected to be open, user U can be prompted to close door 12.

[0123] In the present embodiment, when power button 45a is operated to turn on the power, control unit 52 transitions lock mechanism 13 to the open state. According to this configuration, when a power-on operation is performed on operation unit 41b of washing machine 100, lock mechanism 13 transitions to the open state, so that user U can smoothly perform washing and drying operations with door 12 in the open state.

[0124] In this embodiment, the predetermined operation is an operation of turning on the power externally via communication unit 44. When an operation of turning on the power is performed on power button 45a, control unit 52 transitions lock mechanism 13 to the open state, and when the predetermined operation is performed in a state in which acceptance of the predetermined operation is restricted by restriction unit 60, control unit 52 does not transition lock mechanism 13 to the open state. With this configuration, user U working in front of washing machine 100 can smoothly perform washing and drying operations with door 12 in the open state. Furthermore, when operating washing machine 100 using terminal device 300, safety can be ensured by keeping lock mechanism 13 in the restricted state.

[0125] In this embodiment, the predetermined operation is an operation of turning on the power externally via communication unit 44. When the predetermined operation is performed while restriction unit 60 restricts acceptance of the predetermined operation, and when a predetermined condition related to user U being present within a certain distance from washing machine 100 is satisfied, control unit 52 transitions lock mechanism 13 to the open state. Even if the power-on operation is performed by operating terminal device 300, as long as user U is near washing machine 100, the user can check the situation around washing machine 100. With this configuration, when user U operates terminal device 300 near washing machine 100, door 12 is opened, and washing and drying operations are permitted.

[0126] In the present embodiment, when communication unit 44 is set to communicate with the outside and power button 45a is operated to turn off the power, control unit 52 maintains the communication function of communication unit 44 and transitions lock mechanism 13 to the restricted state. When communication unit 44 is not set to communicate with the outside and power button 45a is operated to turn off the power, control unit 52 turns washing machine 100 to the power-off state without transitioning lock mechanism 13 to the restricted state. With this configuration, when communication unit 44 is not set to communicate with the outside, door 12 can be opened during power standby, allowing washing and drying operations to be performed smoothly.

[0127] In this embodiment, washing machine 100 includes an operation unit (operation 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 operation unit but accepts external operations via communication unit 44. In the special state, control unit 52 accepts external operations via communication unit 44 when lock mechanism 13 is in a restricted state. With this configuration, it is possible to perform work by giving priority to operations of washing machine 100 on terminal device 300.

[0128] Although the embodiment and modifications have been described above, the embodiment and modifications are not limited to the above examples.

[0129] According to at least one embodiment described above, the clothing disposal machine of the embodiment includes a housing, a closing member, a locking mechanism, a communication unit, and a control unit. The housing has an opening through which clothing can be inserted. The closing member closes the opening in an openable and closable manner. The locking mechanism is capable of transitioning 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 clothing disposal machine. The control unit controls the locking mechanism and the communication unit. The restriction unit allows a predetermined operation to be received from the outside via the communication unit when the locking mechanism is in the restricted state, and restricts the reception of the predetermined operation via the communication unit when the locking mechanism is in the open state. This configuration can improve convenience.

[0130] Although several embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are included within the scope and spirit of the invention, as well as within the scope of the invention described in the claims and their equivalents.
