It is preferably realized by using the original conventional buttons and conventional knobs on the computer board of the washing machine, so that it is not necessary to change the hardware on the computer board, and the hardware cost and production man-hours will not be increased.

FIG. 2 is a specific flow chart of an embodiment of selecting a control program through the program selection module in the flow chart of FIG. 1 . There are 6 kinds of control programs stored on the computer board of the described embodiment, and the corresponding washing machine models are respectively: a dual-power washing machine with a washing capacity of 3KG, a dual-power washing machine with a washing capacity of 4.5KG, and a dual-power washing machine with a washing capacity of 5KG , Ordinary pulsator washing machine with a washing capacity of 3KG, an ordinary pulsator washing machine with a washing capacity of 4.5KG, and an ordinary pulsator washing machine with a washing capacity of 5KG.

In the described embodiment, the program selection module includes three buttons, which are respectively the activation button, the selection button and the confirmation button. At the same time, it is also used as an activation button, the "additional rinse" button is also used as a selection button, and the "heating and washing" button is also used as a confirmation button. The specific process of using the three program selection keys to select the control program on the production line is described as follows:

Step S201: the process starts.

Step S202: Power on the computer board.

Step S203: Determine whether to power on while pressing the activation button, that is, the "rinsing times" button. If it is powered on while pressing the activation button, execute step S204, otherwise execute step S209.

Step S204: When it is judged that the computer board is powered on while pressing the activation button, activate the program selection function and enter the program selection state.

Step S205: After entering the program selection state, determine whether to use the selection button, that is, the "additional rinsing" button to select a program. If the selection button is used to select a program, execute step S206, otherwise go to step S207.

The purpose of this judging step is to prevent the operator from misoperation by failing to select a key to select a program after entering the program selection state.

Step S206: Determine whether to use the confirmation button, that is, "heating and washing" for confirmation; if the result is yes, perform step S208, otherwise go to step S207.

After entering the program selection state, the 6 control programs stored on the computer board can be selected in a cycle through the selection button. Select the corresponding control program according to the type of washing machine to be used on the computer board. If the washing machine is a dual-power washing machine with a washing capacity of 4.5KG, then select the corresponding control program for the 4.5KG dual-power washing machine. In order to save the selected control program, a confirmation button is defined for confirmation; and in order to avoid misoperation by the operator, this judgment step is set to eliminate misoperation.

Step S207: If the operator fails to select the control program through the set selection button during the program selection process, or fails to confirm through the set confirmation button after the program selection is completed, the computer board does not respond to the button action and alarms, prompting the operation Personnel error.

The alarm can be in the form of sound and light alarm, or the mode of display module prompt, or the mode of voice prompt, or a combination of multiple alarm modes.

Step S208: Determine whether power-off saving is performed. After selecting the control program corresponding to the washing machine model used by the computer board and confirming with the confirmation button, it is necessary to power off the computer board to keep the selected control program. If power-off saving is performed, go to step S210; otherwise, go to step S209.

Step S209: The computer board executes a default program. This step is transferred from the above step S203 on the one hand, and transferred from the above step S208 on the other hand.
