Embodiment 1
[0010] a kind of like figure 1 The washing machine leakage detection device shown includes: a detection module, which is used to detect whether the washing machine has a leakage phenomenon exceeding the safety of the human body, and outputs the signal to the AD conversion module; an AD conversion module, which is used to digitize the output signal of the detection module , and output to the control module; a control module, used to receive the output signal of the AD conversion module, and then judge whether it exceeds the safety of the human body, and control the power on and off of the buzzer; a power supply circuit, used for the detection module, AD conversion Module, control module and buzzer provide power.
[0011] The detection module of the leakage detection module of the washing machine has two points of contact with the metal shell of the washing machine, and is used to detect whether the washing machine has current or voltage, and outputs the result to the AD conver...
Embodiment 2
[0013] The above washing machine leakage detection device, the detection module is used to detect whether the current exceeds the safe current of the human body or whether the detection voltage exceeds the safe voltage of the human body. When detecting the electric voltage, it is 36V, and when detecting the current is 10mA; The transformer circuit unit, the rectification circuit unit, the filter circuit unit, the voltage stabilization circuit unit, and the voltage stabilization circuit unit are respectively connected with the detection module, the AD conversion module, the control module and the buzzer.
[0014] Based on the above-mentioned embodiments, the leakage detection device of the washing machine can detect at the first time whether the electricity leakage of the laundry exceeds the safe electricity consumption of the human body, and emits a reminder sound, which can well prevent the life of the user due to the leakage. Safety is threatened, and the detection device is ...
