Abstract

The present invention provides a household appliance, which includes a household appliance body and a leakage protection plug electrically connected to the household appliance body, wherein a processing module is provided in the household appliance body, and the leakage protection plug includes a self-test module; The processing module is used for actively sending detection signals to the self-inspection module, and judging whether the leakage protection plug works normally according to the received input signal generated by feedback from the self-inspection module. The beneficial effects of the present invention are: by sending a detection signal from the home appliance body to detect from the self-test module of the leakage protection plug, and receiving the input signal generated by the feedback of the leakage protection plug, it is possible to judge in time whether the leakage protection plug is faulty, and to improve the household electrical appliances. Electrical safety.

Description

technical field [0001] The invention relates to a household appliance. Background technique [0002] In the long-term use of household appliances, it is inevitable that there will be leakage. Leakage has a great impact on human safety. At present, in order to avoid electric leakage of household appliances, many household appliances are provided with electric leakage protection plugs, such as refrigerators, water heaters, washing machines and the like. [0003] However, the existing leakage protection plug is not equipped with a self-test circuit, and its reliability depends entirely on the stability of the device itself. If the leakage protection plug itself fails, it will be very unsafe. Contents of the invention [0004] The purpose of the present invention is to provide a household appliance, which can send a detection signal to the leakage protection plug for detection through the control module in the household appliance body, so as to know whether the leakage prot...
