[0031] The washing machine can be generally divided into a variable frequency washing machine and a non-variable frequency washing machine. At present, the internal structures of circuit boards and controllable loads used by the variable frequency washing machine and the non-variable frequency washing machine are different, and a corresponding detection system and a detection method need to be designed according to the type of the circuit board.

[0037] The embodiments of the present application will be further described below with reference to the accompanying drawings.

[0038] As shown in Figure 1 Figure 1 ​is a flow chart of a washing machine circuit board detection method provided by an embodiment of the present application. The washing machine circuit board detection method can be applied to a washing machine circuit board detection system, which comprises a state detection module, a display module and a control module. The state detection module is used to connect the state port of the circuit board to be detected. The state detection module and the display module are electrically connected with the control module respectively. The washing machine circuit board detection method comprises but is not limited to the following steps:

[0039] In step S110, the state information from the state detection module is acquired.

[0040] In step S120, the type information of the circuit board to be detected is determined according to the state information, wherein the type information comprises a variable frequency board type or a non-variable frequency board type.

[0041] In step S130, the first display information is determined according to the type information.

[0042] In step S140, the first display information is sent to the display module so as to make the display module display the first display information, wherein the first display information is variable frequency board prompt information or non-variable frequency board prompt information.

[0043] In step S150, in the case that the type information is the variable frequency board type, the preset first detection instruction is sent to the circuit board to be detected, so as to make the circuit board to be detected run the preset variable frequency board self-checking program according to the first detection instruction.

[0044] In step S160, in the case that the type information is the non-variable frequency board type, the preset second detection instruction is sent to the circuit board to be detected, so as to make the circuit board to be detected run the preset non-variable frequency board self-checking program according to the second detection instruction.

[0045] It can be understood that the circuit board commonly used in the washing machine can be divided into a variable frequency board and a non-variable frequency board, for example, the model of the variable frequency board includes but is not limited to GEN2, GEN3.0 and GEN3.2, and the model of the non-variable frequency board includes but is not limited to Excalibur and Excalibur D+; after the variable frequency circuit board is powered, the state port of the variable frequency circuit board outputs a live line voltage, and after the non-variable frequency circuit board is powered, the state port of the non-variable frequency circuit board outputs a zero line voltage, therefore, after the state detection module is connected with the state port of the to-be-tested circuit board, the state detection module determines the state information through the voltage output by the state port, the control module can accurately determine the type information of the to-be-tested circuit board, preset corresponding first detection instructions according to the function of the variable frequency board, and preset corresponding second detection instructions according to the function of the non-variable frequency board, so that the detection of to-be-tested circuit boards of various types can be effectively completed; based on this, by setting the state detection module and the control module, because the signals output by the state ports of to-be-tested circuit boards of different types are different, the control module determines the type information of the to-be-tested circuit board by analyzing the state information of the state detection module, then generates first display information and displays the first display information through the display module, so that the detection personnel can quickly determine the type of the circuit board, and then send the first detection instruction or the second detection instruction according to the type of the circuit board, the first detection instruction can effectively trigger the variable frequency board type to-be-tested circuit board to start detection, and the second detection instruction can effectively trigger the non-variable frequency board type to-be-tested circuit board to start detection, without the need to design multiple detection systems and multiple detection methods, resource waste can be avoided, and the detection difficulty can be reduced, thereby improving the detection efficiency.

[0046] It should be noted that the display module can be a display screen or an LED module, when the display module is an LED module, the LED module includes a plurality of LED lamps, each LED lamp is used to indicate one kind of information, for example, the LED lamp group includes LED lamp A and LED lamp B, when the LED module receives the variable frequency board prompt information, the LED lamp A is in the lighting state and the LED lamp B is in the extinguishing state; when the LED module receives the non-variable frequency board prompt information, the LED lamp B is in the lighting state and the LED lamp A is in the extinguishing state.

[0047] In specific practice, after the variable frequency circuit board is powered, the J1-G port of the variable frequency circuit board outputs a live line voltage, and after the non-variable frequency circuit board is powered, the J14-7 port of the non-variable frequency circuit board outputs a live line voltage, the interface types of the J1-G port and the J14-7 port are the same, therefore, the J1-G port and the J14-7 port can be used as the state port of the to-be-tested circuit board, so that the same set of interfaces is used to plug different types of to-be-tested circuit boards; the control module is connected with the input port of the to-be-tested circuit board, and is used to send the first detection instruction or the second detection instruction.

[0048] In addition, with reference to Figure 2In an embodiment, the washing machine circuit board detection system further comprises a motor switching module, the motor switching module being electrically connected with the control module; Figure 1 The step S120 in the illustrated embodiment further comprises, but is not limited to, the following steps:

[0049] Step S210, in the case that the type information is the variable frequency board type, a preset first switching instruction is sent to the motor switching module, so that the motor switching module connects the to-be-detected circuit board with the variable frequency motor module;

[0050] Step S220, in the case that the type information is the non-variable frequency board type, a preset second switching instruction is sent to the motor switching module, so that the motor switching module connects the to-be-detected circuit board with the non-variable frequency motor module.

[0051] It can be understood that, after the type information of the to-be-detected circuit board is determined, the control module controls the motor switching module to switch the connection mode of the to-be-detected circuit board and the motor, for the to-be-detected circuit board of the variable frequency board type, the motor switching module connects the to-be-detected circuit board with the variable frequency motor module; for the to-be-detected circuit board of the non-variable frequency board type, the motor switching module connects the to-be-detected circuit board with the non-variable frequency motor module, which can ensure the effective implementation of the detection process and realize the automatic identification of the to-be-detected circuit board and the automatic matching of the motor.

[0052] It should be noted that the to-be-detected circuit board is connected with the input end of the motor switching module, the variable frequency motor module is connected with the first output end of the motor switching module, the non-variable frequency motor module is connected with the second output end of the motor switching module, and the control module is connected with the control end of the motor switching module, when the control module sends the first switching instruction to the motor switching module through the control end, the motor switching module makes the input end and the first output end conductive, and then the to-be-detected circuit board is connected with the variable frequency motor module; when the control module sends the second switching instruction to the motor switching module through the control end, the motor switching module makes the input end and the second output end conductive, and then the to-be-detected circuit board is connected with the non-variable frequency motor module, which realizes the automatic identification of the to-be-detected circuit board and the automatic matching of the motor.

[0053] In specific practice, the motor switching module can adopt a relay to realize the conduction and disconnection of the circuit.

[0054] In addition, with reference to Figure 3 In an embodiment, the washing machine circuit board detection system further comprises a circuit detection module, the circuit detection module being electrically connected with the control module, the variable frequency motor module comprising a CIM motor and a BPM motor, the CIM motor being provided with a speed measuring coil, one end of the speed measuring coil being connected with a speed measuring port of the to-be-tested circuit board, the other end of the speed measuring coil being connected with the circuit detection module, the first switching instruction being a first sub-switching instruction or a second sub-switching instruction; Figure 2The step S210 in the embodiment shown includes but is not limited to the following steps:

[0055] The step S310 acquires the circuit detection information from the circuit detection module, wherein the circuit detection information includes the first detection information or the second detection information, the first detection information is used to indicate that the to-be-tested circuit board is provided with the rotation speed detection circuit, and the second detection information is used to indicate that the to-be-tested circuit board is not provided with the rotation speed detection circuit.

[0056] The step S320 sends the first sub-switching instruction to the motor switching module to make the motor switching module connect the to-be-tested circuit board with the CIM motor in the case that the type information is the variable frequency board type and the circuit detection information is the first detection information.

[0057] The step S330 sends the second sub-switching instruction to the motor switching module to make the motor switching module connect the to-be-tested circuit board with the BPM motor in the case that the type information is the variable frequency board type and the circuit detection information is the second detection information.

[0058] It can be understood that, in the to-be-tested detection board of the variable frequency board type, for the to-be-tested circuit board matched with the CIM motor, the to-be-tested circuit board is internally provided with the rotation speed detection circuit, and the rotation speed detection circuit can detect the rotation speed value of the speed detection coil located on the CIM; for the to-be-tested circuit board matched with the BPM motor, the to-be-tested circuit board is not internally provided with the rotation speed detection circuit; therefore, the circuit detection module is arranged in the washing machine circuit board detection system, and the circuit detection information of the circuit detection module can effectively determine whether the to-be-tested circuit board is provided with the rotation speed detection circuit; for the to-be-tested circuit board provided with the rotation speed detection circuit, the motor switching module switches the to-be-tested circuit board to be connected with the CIM motor; for the to-be-tested circuit board not provided with the rotation speed detection circuit, the motor switching module switches the to-be-tested circuit board to be connected with the BPM motor, which can ensure the effective implementation of the detection process and realize the automatic identification of the to-be-tested circuit board and the automatic matching of the motor.

[0059] It should be noted that the to-be-tested circuit board is connected with the input end of the motor switching module, the first output end of the motor switching module is divided into a first sub-output port and a second sub-output port, the CIM motor is connected with the first sub-output end of the motor switching module, and the BPM motor is connected with the second sub-output end of the motor switching module; when the control module sends the first sub-switching instruction to the motor switching module through the control end, the motor switching module makes the input end and the first sub-output end conductive, and then the to-be-tested circuit board is connected with the CIM motor; when the control module sends the second sub-switching instruction to the motor switching module through the control end, the motor switching module makes the input end and the second sub-output end conductive, and then the to-be-tested circuit board is connected with the BPM motor, which realizes the automatic identification of the to-be-tested circuit board and the automatic matching of the motor.

[0060] It is worth noting that the CIM motor refers to a computer integrated manufacturing (CIM) motor, and the BPM motor refers to a brushless permanent magnet motor (BPM) motor.

[0061] In addition, after step S160 in the embodiment shown in Figure 4 , Figure 1 , the following steps are further included, but are not limited to:

[0062] Step S410, receiving self-check feedback information from the to-be-tested circuit board;

[0063] Step S420, determining second display information according to the self-check feedback information;

[0064] Step S430, sending the second display information to the display module, so that the display module displays the second display information, wherein the second display information at least includes one of the following: water inlet valve port state information, drain pump port state information, heating pipe port state information, fan port state information, motor port state information and motor rotation state information.

[0065] It can be understood that the to-be-tested circuit board will generate self-check feedback information when performing self-checking according to the self-checking program, and the control module analyzes the self-check feedback information to determine the second display information. During the self-checking process of the to-be-tested circuit board, the water inlet valve port, the drain pump port, the heating pipe port, the fan port and the motor port can be detected to determine whether each port can be normally opened or closed, and the motor rotation process can also be detected to determine whether the forward and reverse rotation of the motor is normal, and whether the rotation speed of the motor is normal. Therefore, the second display information can include the water inlet valve port state information, the drain pump port state information, the heating pipe port state information, the fan port state information, the motor port state information and the motor rotation state information, and the corresponding self-checking program can be set according to the functional needs of the to-be-tested circuit board.

[0066] In addition, after step S410 in the embodiment shown in Figure 5 , Figure 4 , the following steps are further included, but are not limited to:

[0067] Step S510, performing abnormal analysis on the self-check feedback information to obtain an analysis result;
