[0018] Main control unit 50 is a control unit that performs overall control of washing machine 1. 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 1. Main microcomputer 52 is an example of a "control microcomputer."

[0019] <2. Control system related configuration> Next, the configuration related to the control system will be described. 2 is a block diagram showing the configuration related to the control system. The washing machine 1 includes, for example, an electrical component EC, a nonvolatile storage unit 53, a network connection adapter 61, and a data output connector 62.

[0020] <2.1 Various parts> The electrical components EC are electrical components included in the washing machine 1. Examples of the electrical components EC include the motor 15, the water supply valve 21, the drain valve 26, or the blower 34 described above. The electrical components EC are connected to the main microcomputer 52 via signal lines (not shown). The electrical components EC operate based on control commands from the main microcomputer 52. The electrical components EC output information indicating the state of the electrical components EC or the washing machine 1 to the main microcomputer 52 at predetermined intervals or when predetermined conditions are satisfied.

[0021] Nonvolatile storage unit 53 is a storage unit included in washing machine 1. Nonvolatile storage unit 53 is a storage unit that can retain data even when washing machine 1 is switched off. Nonvolatile storage unit 53 is, but is not limited to, a flash memory or an EEPROM (Electrically Erasable Programmable Read-Only Memory). Nonvolatile storage unit 53 is connected to main microcomputer 52 via a signal line (not shown). Note that nonvolatile storage unit 53 may be provided inside main microcomputer 52 (as part of main microcomputer 52) instead of being provided outside main microcomputer 52.

[0022] Nonvolatile storage unit 53 stores, for example, information relating to the operation history of washing machine 1 (hereinafter referred to as "operation history information HI"). Operation history information HI includes information relating to the operation history of components that are powered off when data is output to external device 400 (when a predetermined condition is met), which will be described later. "Components that are powered off when data is output to external device 400 (when a predetermined condition is met)" is, for example, internet connection adapter 61. Operation history information HI includes, for example, operation history and abnormality information (e.g., error history) of one or more of electrical components EC, display / input unit 41, vibration sensor unit 42, heat pump control unit 43, and internet connection adapter 61.

[0023] Network connection adapter 61 (hereinafter referred to as "network connection adapter 61") is an adapter for communicating with external server 200 (server 200 on a network). Network connection adapter 61 is a connection adapter for sending and receiving information about washing machine 1 to and from server 200. Network connection adapter 61 is a component that can communicate with main microcomputer 52 at least when washing machine 1 is operating. Network connection adapter 61 is an example of a "first component."

[0024] The network connection adapter 61 is connected to a network via, for example, a wireless router and a modem installed in the same user's residence as the washing machine 1, and is capable of communicating with the server 200 via the network. For example, the network connection adapter 61 is an adapter capable of communicating with the wireless router via Wi-Fi. Examples of the network include 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, as appropriate. The server 200 is capable of communicating with an external terminal device 300. The terminal device 300 may be, but is not limited to, a smartphone, a tablet device, a personal computer, or the like.

[0025] Under the control of main microcomputer 52, network connection adapter 61 transmits and receives predetermined information to and from server 200. Information transmitted from network connection adapter 61 to server 200 includes the status of washing machine 1, its operation history, and abnormality information.

[0026] The information transmitted from network connection adapter 61 to server 200 is, for example, information to be displayed on terminal device 300 when using terminal device 300 to check the status of washing machine 1 or to remotely operate washing machine 1. The information to be displayed on terminal device 300 is, for example, the status of washing machine 1 (the operation course currently being executed, the process currently being executed (progress of operation), the estimated time until completion of operation, the type and remaining amount of laundry treatment agent such as detergent or fabric softener contained in the automatic dispenser, etc.), and information used to schedule operation of washing machine 1 (the operation courses that can be executed by washing machine 1, the type and / or remaining amount of laundry treatment agent such as detergent or fabric softener contained in the automatic dispenser, etc.).

[0027] On the other hand, the information transmitted from the server 200 to the Internet connection adapter 61 includes, for example, information indicating the operation contents or reservation contents set by the user using the terminal device 300, and information indicating the contents of the operation course to be added to the washing machine 1.

[0028] The internet connection adapter 61 is a component that can control the power supply (can switch the power supply to an off state) independently of the power supply of the washing machine 1. For example, the washing machine 1 can be set to a mode (offline mode) in which it does not communicate with the server 200 based on a user's operation. When the washing machine 1 is set to the offline mode, the main microcomputer 52 can switch the power supply of the internet connection adapter 61 to an off state using a signal line 95 (for example, a dedicated control line).

[0029] In this embodiment, the main microcomputer 52 can switch the power supply of the internet connection adapter 61 between an ON state and an OFF state by controlling the power supply hardware based on the voltage level of the voltage applied to the signal line 95. For example, the main microcomputer 52 can control the power supply of the internet connection adapter 61 to an ON state by setting the voltage applied to the signal line 95 to a High level, and can control the power supply of the internet connection adapter 61 to an OFF state by setting the voltage applied to the signal line 95 to a Low level. In this configuration, when the washing machine 1 is set to offline mode, the main microcomputer 52 switches the power supply of the internet connection adapter 61 from an ON state to an OFF state by setting the voltage applied to the signal line 95 to a Low level. As a result, the power supply of the internet connection adapter 61 is turned OFF while the power supply of the washing machine 1 remains ON. Alternatively, when the washing machine 1 is set to offline mode, the main microcomputer 52 may switch the power supply of the internet connection adapter 61 to an OFF state using a communication command.

[0030] The data output connector 62 is a component that can output data to the external device 400 when a predetermined condition, which will be described later, is satisfied. In this application, "capable of outputting data to the external device" is not limited to the case where data can be output directly to the external device 400, but may also include the case where data can be output to the external device 400 via a relay device RD, which will be described later. The data output connector 62 is an example of a "second component."

[0031] Data output connector 62 is directly or indirectly connected to, for example, external device 400 present in the same user's residence as washing machine 1, and is capable of communicating with external device 400. "Indirectly connected" means, for example, that there is another relay device RD (for example, a device that converts signals or a device with wireless communication capabilities) between data output connector 62 and external device 400. Communication between data output connector 62 and external device 400 may be wireless, wired, or partly wireless and partly wired, etc.

[0032] External device 400 is, for example, a device used by a serviceman for repair or maintenance of washing machine 1. External device 400 is, but is not limited to, a smartphone, a tablet terminal, a personal computer, or the like. External device 400 may also be a device dedicated to repair or maintenance of washing machine 1.

[0033] The information output from data output connector 62 to external device 400 is, for example, information that can be used for repair or maintenance of washing machine 1. The information output from data output connector 62 to external device 400 is, for example, information including the operation history and / or abnormality information of washing machine 1. The information output from data output connector 62 to external device 400 is, for example, operation history information HI stored in non-volatile storage unit 53.

[0034] 2.2 Configuration related to the main microcontroller Next, the main microcomputer 52 will be described. The main microcomputer 52 has a plurality of communication terminals (communication ports) 71-78 in addition to the terminals connected to the electrical components EC. The communication terminals 71-78 are terminals that comply with a predetermined communication standard. For example, the communication terminals 71-78 are terminals that comply with UART (Universal Asynchronous Receiver Transmitter). Each of the communication terminals 71-78 transmits or receives a signal using a pulse defined by a high level (5V) and a low level (0V), for example.

[0035] The communication terminals 71 and 72 are connected to the microcomputer 41c of the display / input unit 41 and are capable of communicating with the microcomputer 41c. For example, the communication terminal 71 is connected to the microcomputer 41c via a communication line 81 and is a transmission terminal through which information transmitted from the main microcomputer 52 to the microcomputer 41c is output. The communication terminal 72 is connected to the microcomputer 41c via a communication line 82 and is a reception terminal through which information transmitted from the microcomputer 41c to the main microcomputer 52 is received.

[0036] The communication terminals 73 and 74 are connected to the microcomputer 42b of the vibration sensor unit 42 and are capable of communicating with the microcomputer 42b. For example, the communication terminal 73 is connected to the microcomputer 42b via a communication line 83 and is a transmitting terminal through which information transmitted from the main microcomputer 52 to the microcomputer 42b is output. The communication terminal 74 is connected to the microcomputer 42b via a communication line 84 and is a receiving terminal through which information transmitted from the microcomputer 42b to the main microcomputer 52 is received.

[0037] The communication terminals 75 and 76 are connected to the microcomputer 43b of the heat pump control unit 43 and are capable of communicating with the microcomputer 43b. For example, the communication terminal 75 is connected to the microcomputer 43b via a communication line 85 and is a transmitting terminal through which information transmitted from the main microcomputer 52 to the microcomputer 43b is output. The communication terminal 76 is connected to the microcomputer 43b via a communication line 86 and is a receiving terminal through which information transmitted from the microcomputer 43b to the main microcomputer 52 is received.

[0038] The communication terminals 77 and 78 are terminals that are connected to the network connection adapter 61 and are capable of communicating with the network connection adapter 61. For example, the communication terminal 77 is connected to the network connection adapter 61 via a communication line 87 and is a transmitting terminal that outputs information transmitted from the main microcomputer 52 to the network connection adapter 61. The communication terminal 78 is connected to the network connection adapter 61 via a communication line 88 and is a receiving terminal that receives information transmitted from the network connection adapter 61 to the main microcomputer 52. The communication terminal 77 is an example of a "first terminal." The communication line 87 is an example of a "first communication line." For ease of explanation, the communication line 87 will be referred to as the "first communication line 87" below.

[0039] In this embodiment, one end of a communication line 89 is connected to the middle of the communication line 87. The other end of the communication line 89 is connected to the data output connector 62. The communication line 89 is an example of a "second communication line." For convenience of explanation, the communication line 89 will be referred to as the "second communication line 89" below.

[0040] In this embodiment, the data output connector 62 is connected to the communication terminal 77 of the main microcomputer 52 via a second communication line 89 branching off from the middle of the first communication line 87, and is capable of outputting data to the external device 400 when a predetermined condition is met. The predetermined condition is, for example, that another component (e.g., the external device 400 or the relay device RD) is connected to the data output connector 62. Note that in this application, "connected to the main microcomputer (control microcomputer) via a second communication line branching off from the middle of the first communication line" includes the case where the main microcomputer is connected to the main microcomputer via a part of the first communication line in addition to the second communication line, as shown in FIG. 2.

[0041] In this embodiment, first communication line 87 and second communication line 89 are pulled up to a predetermined voltage (for example, 5 V or 3.3 V) when the above-mentioned predetermined conditions are not met, and 0 V is input when the above-mentioned predetermined conditions are met. To explain a specific example, a wire 93 is connected midway through second communication line 89. Wiring 93 is connected to voltage supply source 91 via resistor 92. Voltage supply source 91 may be, for example, (1) a power supply provided inside washing machine 1, or (2) a power supply provided in an external relay device RD (for example, an EEPROM reader).

[0042] The example of (1) above is an example in which power is not supplied from relay device RD (for example, an EEPROM reader) but an internal power supply of washing machine 1 is used. For example, in the example of (1) above, an internal power supply of 5V DC that is rectified and stepped down from a general external commercial power supply (100V AC) is used as voltage supply source 91. In this case, voltage supply source 91 is used as a power supply for main microcomputer 52 and also as a pull-up power supply.

[0043] On the other hand, in the example (2) above, the internal power supply of washing machine 1 is cut off, and DC power of a predetermined voltage is supplied from the battery power supply of an external relay device RD (e.g., an EEPROM reader). For example, in the example (2) above, a 3.3V DC battery power supply mounted on external relay device RD (e.g., an EEPROM reader) is used as voltage supply source 91. In this case, voltage supply source 91 is also used as a power supply for main microcomputer 52 and as a pull-up power supply. The reason why the battery power supply of relay device RD is 3.3V is as follows. That is, if the battery power supply of relay device RD is 5V, there is a possibility of an overvoltage failure if 5V power is mistakenly supplied to main microcomputer 52, which operates at 3.3V. On the other hand, main microcomputer 52, which operates at 5V, can operate with 3.3V power. The battery power supply of relay device RD may be 5V instead of 3.3V.

[0044] When the power supply of the washing machine 1 is turned off, the voltage supply source 91 can apply the above-mentioned predetermined voltage to the first communication line 87 and the second communication line 89. The above-mentioned predetermined voltage (for example, 5 V or 3.3 V) is an example of a "first voltage level" and an example of a "High level."

[0045] If the above-mentioned predetermined condition is not satisfied (for example, if the external device 400 or the relay device RD is not connected to the data output connector 62), a predetermined voltage (for example, 5 V) is applied to the first communication line 87 and the second communication line 89 via a resistor 92. In this case, the above-mentioned predetermined voltage (for example, 5 V) is input to the terminal 77 of the main microcomputer 52.

[0046] On the other hand, when the above-mentioned predetermined condition is satisfied (for example, when the external device 400 or the relay device RD is connected to the data output connector 62), the data output connector 62 and the external device 400 or the relay device RD are brought into a conductive state, and the voltage levels of the first communication line 87 and the second communication line 89 are pulled to 0V. In this case, 0V is substantially input to the terminal 77 of the main microcomputer 52. 0V is an example of the "second voltage level" and an example of the "low level."

[0047] 3 is a diagram illustrating the configuration of the second communication line 89. In this embodiment, the network connection adapter 61 is disposed separately from the circuit board 51 on which the main microcomputer 52 is mounted. The circuit board 51 has, for example, a connector CT1. The network connection adapter 61 has, for example, a cable CA compatible with UART and a connector CT2 provided at the end of the cable CA. The network connection adapter 61 is connected to the circuit board 51 via the cable CA by connecting the connector CT2 to the connector CT1.

[0048] The above-mentioned communication line 87 includes a first portion 87a that is wiring provided on the circuit board 51 and a second portion 87b that is wiring within the cable CA. Similarly, the above-mentioned communication line 88 includes a first portion 88a that is wiring provided on the circuit board 51 and a second portion 88b that is wiring within the cable CA.

[0049] On the other hand, the data output connector 62 is mounted on the circuit board 51 on which the main microcomputer 52 is mounted. The above-mentioned communication line 89 is a wiring provided on the circuit board 51. The communication line 89 is connected to the middle of the first portion 87a of the first communication line 87 at a connection point 51a provided on the circuit board 51. The above-mentioned pull-up resistor 92 and wiring 93 may also be provided on the circuit board 51.

[0050] <2.3 Relay device configuration> Next, an example of the relay device RD will be described. 4 is a diagram for explaining an example of a relay device RD. In this embodiment, the data output connector 62 outputs data to an external device 400 via the relay device RD.

[0051] The relay device RD includes, for example, an I2C conversion circuit 101 and a short-range wireless communication module 102. The I2C conversion circuit 101 converts a signal compatible with UART into a signal compatible with I2C (Inter-Integrated Circuit) communication. The short-range wireless communication module 102 includes a short-range wireless communication circuit and an antenna. The short-range wireless communication module 102 transmits the signal converted by the I2C conversion circuit 101 to the external device 400 via short-range wireless communication such as Bluetooth (registered trademark). Note that, instead of the above example, the relay device RD may include a device including the I2C conversion circuit 101 and a device including the short-range wireless communication module 102, which are separate devices.

[0052] The reason for converting to I2C communication is that when used in common with washing machines or other home appliances (refrigerators, etc.), the communication terminals of the EEPROM device are often directly connected to connectors, making it easier to service and repair them by sharing the same signal with them. The signal converted to I2C communication is converted into a signal for short-range wireless communication, and the operation history and abnormality information are displayed on external device 400.

[0053] <3. Operation of the main microcomputer> 2, the operation of the main microcomputer 52 will be described. In this embodiment, when the main microcomputer 52 is started up (including when it is restarted), the main microcomputer 52 determines the operation mode based on the voltage level input to the communication terminal 77 to which the first communication line 87 is connected.

[0054] For example, main microcomputer 52 determines to operate washing machine 1 in the first mode (normal mode, operation mode) when a predetermined voltage (e.g., 5 V) is input to terminal 77 upon startup of main microcomputer 52. The first mode is an operation mode in which washing machine 1 is operated based on the user's operation.

[0055] On the other hand, if the predetermined voltage is not input to communication terminal 77 when main microcomputer 52 is started (for example, if 0 V is input), main microcomputer 52 determines to operate washing machine 1 in the second mode (data output mode). The second mode is an operation mode in which data is output from data output connector 62 (outputs data to external device 400). When main microcomputer 52 operates in the second mode, it outputs data related to the operation history and / or abnormality information of washing machine 1 from communication terminal 77. For example, when main microcomputer 52 operates in the second mode, it reads information related to the operation history and abnormality information of washing machine 1 (for example, operation history information HI) from nonvolatile storage unit 53 and outputs the information from communication terminal 77.

[0056] <4. Operation flow> Next, the flow of operations of the washing machine 1, relay device RD, and external device 400 will be described with reference to Fig. 5 to Fig. 7. The operations shown in Fig. 5 to Fig. 7 are examples when the power of the washing machine 1 is off. In this embodiment, when a malfunction occurs in the washing machine 1, a service technician performing repairs or maintenance connects the relay device RD to the washing machine 1 that is off, and performs an operation to start up the main microcomputer 52 using, for example, the power source of the relay device RD.

[0057] <4.1 Example of washing machine operation> 5 is a flowchart showing the operation of the main microcomputer 52. When the main microcomputer 52 is started, the main microcomputer 52 determines whether the voltage level input to the communication terminal 77 of the main microcomputer 52 is low (e.g., 0 V) ​​(S101). If the voltage level input to the communication terminal 77 is not low (S101: NO), the main microcomputer 52 determines to operate in the first mode (normal mode). In this case, the main microcomputer 52, for example, switches the power of the internet connection adapter 61 to the on state. Note that, if a predetermined condition is satisfied, the main microcomputer 52 may keep the power of the internet connection adapter 61 in the off state even when operating in the first mode (normal mode). The predetermined condition is, for example, when there is no setting information regarding at least one of the SSID (Service Set Identifier) ​​and password for the wireless LAN.

[0058] On the other hand, if the voltage level input to the communication terminal 77 is low (S101: YES), the main microcomputer 52 determines to operate in the second mode (data output mode). In this case, the main microcomputer 52 keeps the power of the internet connection adapter 61 turned off (S102).

[0059] Next, the main microcomputer 52 outputs, for example, all of the data (for example, 256 bytes of data) stored in the nonvolatile storage unit 53 from the communication terminal 77 (S103). Then, the main microcomputer 52 determines whether or not the output of all of the data has been completed (S104). If the output of all of the data has not been completed (S104: NO), the main microcomputer 52 continues to output the data. On the other hand, if the output of all of the data has been completed (S104: YES), the main microcomputer 52 ends its operation.

[0060] <4.2 Operation example of I2C conversion circuit> FIG. 6 is a flowchart showing the operation of the I2C conversion circuit 101. First, the I2C conversion circuit 101 displays, using a lighting unit (e.g., a light-emitting diode) that can be seen from outside the relay device RD, that reception is incomplete (S201). Next, the I2C conversion circuit 101 determines whether or not the start of UART communication (e.g., a UART start bit) has been detected (S202). If the I2C conversion circuit 101 has not detected the start of UART communication (S202: NO), it continues monitoring. If the I2C conversion circuit 101 detects the start of UART communication (S202: YES), it receives data (e.g., 256 bytes of data) through the data output connector 62 (S203). In this case, the I2C conversion circuit 101 continues receiving data until a predetermined number of bytes have been received. The number of bytes is included in the received data.

[0061] Next, the I2C conversion circuit 101 determines whether all data (for example, 256 bytes of data) has been received (S204). If the I2C conversion circuit 101 has not received all data (S204: NO), it continues receiving data. On the other hand, if the I2C conversion circuit 101 has received all data (S204: YES), it uses the lighting unit to display an indication that reception has been completed and that the circuit is in read standby mode (S205).

[0062] Next, the I2C conversion circuit 101 determines whether or not there is a read request from the short-range wireless communication module 102 (S206). If the I2C conversion circuit 101 does not receive the read request, it continues to wait. On the other hand, if the I2C conversion circuit 101 receives the read request, it transmits all data (e.g., 256 bytes of data) received from the data output connector 62 to the short-range wireless communication module 102 via I2C communication (S207).

[0063] Then, the I2C conversion circuit 101 determines whether transmission of all data (for example, 256 bytes of data) is complete (S208). If transmission of all data is not complete (S208: NO), the I2C conversion circuit 101 continues transmitting data. On the other hand, if transmission of all data is complete (S208: YES), the I2C conversion circuit 101 ends operation.

[0064] 7 is a flowchart showing the flow of operations of the short-range wireless communication module 102 and the external device 400. First, the short-range wireless communication module 102 determines whether or not a user has performed a read start operation (for example, an operation on an operation unit provided in the relay device RD) (S301). If a read start operation has not been performed (S301: NO), the short-range wireless communication module 102 continues to wait until a read start operation is performed. If a read start operation has been performed (S301: YES), the short-range wireless communication module 102 transmits a read request to the I2C conversion circuit 101 and receives data (for example, 256 bytes of data) from the I2C conversion circuit 101 using I2C communication (S302).

[0065] Next, the short-range wireless communication module 102 determines whether all the data (e.g., 256 bytes of data) has been received (S303). If the short-range wireless communication module 102 has not received all the data (S303: NO), it continues receiving data. On the other hand, if the short-range wireless communication module 102 has received all the data (e.g., 256 bytes of data) from the I2C conversion circuit 101, it transmits all the data (e.g., 256 bytes of data) received from the I2C conversion circuit 101 to the external device 400 by short-range wireless communication (S304).

[0066] Then, the short-range wireless communication module 102 determines whether transmission of all data (for example, 256 bytes of data) has been completed (S305). If transmission of all data has not been completed (S305: NO), the short-range wireless communication module 102 continues transmitting data. On the other hand, if transmission of all data has been completed (S305: YES), the short-range wireless communication module 102 ends operation. If the external device 400 receives the data transmitted from the short-range wireless communication module 102, it displays the reception on a display screen of the external device 400 or the like.

[0067] <5. Another example of operation> <5.1 Another example of operation 1> Alternatively to the above example, if a malfunction occurs in washing machine 1, a service technician performing repairs or maintenance may turn off the power of network connection adapter 61 (set it to offline state) and start or restart washing machine 1 with relay device RD connected to washing machine 1. Even with this procedure, 0V is input to communication terminal 77 of main microcomputer 52 when main microcomputer 52 is started, and main microcomputer 52 determines to operate in the second mode (data output mode).

[0068] <5.2 Another example of operation 2> If a malfunction occurs in washing machine 1, a service technician performing repairs or maintenance may turn off the power of internet connection adapter 61 and acquire data output from data output connector 62 while washing machine 1 is operating in the first mode (normal mode). For example, when washing machine 1 is operated with internet connection adapter 61 powered off, main microcomputer 52 outputs data related to the operating state of washing machine 1 during operation (real-time data, for example, data that is not stored in nonvolatile storage unit 53, for example, data transmitted from washing machine 1 to server 200 in normal mode) from communication terminal 77. This operation is performed, for example, when relay device RD or external device 400 is connected to data output connector 62 while internet connection adapter 61 is powered off.

[0069] <6. Advantages> The control microcomputer of the clothing processing machine (for example, the main microcomputer) may require a terminal (first specified terminal) with a communication function that is connected to the network connection adapter 61 in order to communicate with the server. The control microcomputer of the clothing processing machine also preferably has a terminal (second specified terminal) with a communication function that is connected to the data output connector 62 in order to read data directly from the clothing processing machine during service visits and perform fault diagnosis, etc. In order to achieve both of these, the control microcomputer needs to have many communication terminals.

[0070] On the other hand, in home appliances such as laundry disposal machines, narrowing the pin pitch of the microcontroller can cause solder bridges due to factors such as the material of the circuit board and manufacturing equipment, so there is a tendency to use microcontrollers with wider pin pitches. Therefore, ensuring many communication terminals on the control microcontroller can lead to increased manufacturing costs for the laundry disposal machine. For this reason, it may be desirable to reduce the number of communication terminals required for the control microcontroller.

[0071] Therefore, in this embodiment, washing machine 1 has main microcomputer 52, a first component (e.g., network connection adapter 61), and a second component (e.g., data output connector 62). The first component is connected to communication terminal 77 of main microcomputer 52 via first communication line 87 and is capable of communicating with main microcomputer 52. The second component is connected to communication terminal 77 of main microcomputer 52 via second communication line 89 branching from the middle of first communication line 87 and is capable of outputting data to external device 400 when a predetermined condition is satisfied. With this configuration, both network connection and reading of data to external device 400 can be achieved with a small number of communication terminals. This reduces the number of communication terminals required for the control microcomputer.

[0072] In this embodiment, the second communication line 89 is pulled up to a high-level voltage, which is a predetermined voltage, when the predetermined condition is not satisfied, and a low-level voltage is input when the predetermined condition is satisfied. With this configuration, the main microcomputer 52 operates in the first mode (normal mode) as is during normal startup, and a low-level voltage is input when the main microcomputer 52 is started up to read data from the external device 400, allowing the main microcomputer 52 to determine and switch modes. This improves convenience.

[0073] In this embodiment, the first component is a component that can be switched off independently of the power supply of the washing machine 1. When the washing machine 1 is operated with the power supply of the first component turned off, the main microcomputer 52 can output data relating to the operating status of the washing machine 1 during operation from the communication terminal 77. With this configuration, the latest operating data (real-time operating data) of the washing machine 1 at that time is output, making it easier to diagnose and repair the washing machine 1.

[0074] In this embodiment, washing machine 1 includes nonvolatile storage unit 53 that stores information about the operation history of washing machine 1. When the above-described predetermined condition is satisfied, main microcomputer 52 reads information about the operation history of washing machine 1 from nonvolatile storage unit 53 and outputs it from communication terminal 77. With this configuration, data that is not stored in nonvolatile storage unit 53 is also output, making it easier to diagnose and repair washing machine 1.

[0075] In this embodiment, the information on the operation history of washing machine 1 output from communication terminal 77 when the above-mentioned predetermined condition is satisfied includes information on the operation history of the first component that is powered off when the above-mentioned predetermined condition is satisfied. With this configuration, it becomes easier to check the state of the first component, whose state cannot be checked because it is powered off when data is output from data output connector 62.

[0076] (Second embodiment) Next, a second embodiment will be described. The second embodiment differs from the first embodiment in that a short-range wireless communication module 151 is provided instead of the data output connector 62. Note that the configuration other than that described below is the same as that of the first embodiment.

[0077] 8 is a block diagram showing a configuration related to a control system of the second embodiment. In this embodiment, washing machine 1 has a short-range wireless communication module 151 instead of data output connector 62. Short-range wireless communication module 151 can transmit data to external device 400 by close proximity wireless communication such as Bluetooth (registered trademark). Short-range wireless communication module 151 is an example of a "short-range wireless communication adapter" and an example of a "second component."

[0078] In this embodiment, the second component is a short-range wireless communication module 151. With this configuration, data can be output directly to an external device 400 having a short-range wireless communication function when read. This reduces the amount of luggage required for diagnosis during repair service, etc.

[0079] (Third embodiment) Next, a third embodiment will be described. The third embodiment differs from the first embodiment in that a second communication line 89 branches off from the communication line 83 connected to the microcomputer 42b of the vibration sensor unit 42. Note that the configuration other than that described below is the same as that of the first embodiment.

[0080] 9 is a block diagram showing the configuration related to the control system of the third embodiment. A communication terminal 73 of the main microcomputer 52 and a microcomputer 42b of the vibration sensor unit 42 are connected by a communication line 83. The vibration sensor unit 42 is a sensor that detects vibrations during, for example, a spin cycle, and is powered off except during a spin cycle. This makes it easy to share the communication output with the data output connector 62. For example, data can be output from the data output connector 62 even when the power to the washing machine 1 is on (for example, while the washing machine 1 is operating).

[0081] In this embodiment, the communication terminal 73 of the main microcomputer 52 is an example of a "first terminal." The microcomputer 42b is an example of a "first component." The microcomputer 42b is a component that can communicate with the main microcomputer 52 at least when the washing machine 1 is operating. The microcomputer 42b is an electrical component that is used while the washing machine 1 is operating. In this embodiment, the communication line 83 is an example of a "first communication line." For the sake of convenience, the communication line 83 will be referred to as the "first communication line 83" below.

[0082] In the present embodiment, data output connector 62 is connected to communication terminal 73 of main microcomputer 52 via second communication line 89 branching from the middle of first communication line 83, and is capable of outputting data to external device 400 when a predetermined condition is satisfied. The configuration of data output connector 62 is the same as that of the first embodiment. With this configuration, data can be output to external device 400 by using a communication line connected to a device other than the one that is always operating when washing machine 1 is in operation.

[0083] Alternatively, second communication line 89 may branch off from communication line 85 connected to microcomputer 43b of heat pump control unit 43. Heat pump control unit 43 is an electrical component used, for example, during drying operation, and is powered off except during drying operation. This makes it easy to share the communication output with data output connector 62. For example, data can be output from data output connector 62 even when washing machine 1 is powered on (for example, while washing machine 1 is operating).

[0084] In this example, communication terminal 75 of main microcomputer 52 is an example of a "first terminal." Microcomputer 43b is an example of a "first component." Microcomputer 43b is a component that can communicate with main microcomputer 52 at least when washing machine 1 is operating. Microcomputer 43b is an electrical component that is used while washing machine 1 is operating. Communication line 85 is an example of a "first communication line." With this configuration, data can be output to external device 400 using a communication line connected to a device other than one that is constantly operating when washing machine 1 is operating.

[0085] Several embodiments have been described above. Note that the embodiments are not limited to the examples described above. For example, multiple embodiments may be implemented in combination with each other. For example, the configuration of the third embodiment (wherein the first component is an electrical component used while the washing machine 1 is running) and the configuration of the second embodiment (wherein the near field wireless communication module 151 is provided instead of the data output connector 62) may be implemented in combination.

[0086] For example, second communication line 89 may branch off from communication line 81 connected to microcomputer 41c of display / input unit 41. Even in this case, for example, if power can be supplied to at least some functions of main microcomputer 52 when washing machine 1 is powered off, communication output can be shared between microcomputer 41c of display / input unit 41 and data output connector 62. In this case, communication terminal 71 of main microcomputer 52 is an example of a "first terminal." Microcomputer 41c is an example of a "first component." Microcomputer 41c is a component that can communicate with main microcomputer 52 at least when washing machine 1 is operating. Microcomputer 41c is an electrical component used while washing machine 1 is operating. Communication line 81 is an example of a "first communication line."

[0087] According to at least one embodiment described above, the laundry processing machine includes a control microcomputer, a first component, and a second component. The control microcomputer has a first terminal. The first component is connected to the first terminal of the control microcomputer via a first communication line and is capable of communicating with the control microcomputer. The second component is connected to the first terminal of the control microcomputer via a second communication line branching from the first communication line and is capable of outputting data to an external device when a predetermined condition is met. This configuration reduces the number of communication terminals required for the control microcomputer.

[0088] In the above-described embodiment, the main microcomputer 52 determines to operate in the second mode (data output mode) when a low-level voltage is input to the communication terminal 77. Alternatively or additionally, the main microcomputer 52 may vary the data to be output depending on the change pattern (pattern signal) of the voltage input to the communication terminal 77.

[0089] 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.
