An embodiment of the present disclosure provides a control device for self-cleaning of a washing machine. FIG. 1 is a schematic diagram of a self-cleaning control device for a washing machine according to an embodiment of the present disclosure. As shown in FIG. The self-cleaning control device of the washing machine includes: an excitation part and an induction part 1021; the excitation part is arranged in the base part 101 of the washing machine, and is used to send out an induction signal when it is operated; the induction part 1021 is arranged in the In the main unit 102 of the washing machine, the sensing signal is received, and when the sensing signal satisfies a preset condition, the main unit 102 is triggered to perform a self-cleaning action.

Here, the washing machine is any type of washing machine that can be used in daily life, such as a hand push washing machine, an electric washing machine, etc. The type of the washing machine is not limited in this embodiment.

The excitation part can be set in the base part 101 of the washing machine, and the induction part 1021 can be set in the main body part 102 of the washing machine.

The sensing part 1021 receives the sensing signal whose signal strength changes, and when the strength of the sensing signal reaches the preset threshold, it indicates that the sensing part 1021 receives the sensing signal satisfying the preset condition, and further triggers the host part based on the sensing signal 102 starts executing the self-cleaning action. In other optional embodiments, when the user's foot acts on the excitation part, the excitation part sends out a sensing signal, so that the sensing part 1021 receives the sensing signal, and correspondingly, the sensing When the unit 1021 receives the sensing signal, it indicates that the sensing signal satisfying the preset condition is received, and further triggers the host unit 102 to start the self-cleaning action based on the sensing signal.

Wherein, the change of the position of the excitation part corresponds to the change of the signal strength received by the sensing part 1021. Exemplarily, when the user's foot does not act on the excitation part, the excitation part is farther away from the excitation part. The sensing part 1021 is the farthest, correspondingly, the signal strength received by the sensing part 1021 is the smallest; when the user's foot acts on the exciting part, the distance between the exciting part and the sensing part 1021 gradually decreases When the distance between the excitation part and the sensing part 1021 is the smallest, the signal strength received by the sensing part 1021 is the largest.
