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 ...

Abstract

The invention belongs to the field of household electrical appliances and particularly relates to an electric leakage detection device of a washing machine. The electric leakage detection device of the washing machine comprises a detection module, an AD (Analog-to-Digital) conversion module, a control module and a power circuit, wherein the detection module is used for detecting whether electricity exceeding the safety of a human body leaks from the washing machine, and outputting a signal to the AD conversion module; the AD conversion module is used for digitizing the signal output by the detection module and outputting the digitized signal to the control module; the control module is used for receiving the signal output by the AD conversion module, judging whether the electricity exceeds the safety of the human body, and controlling the on and off of a buzzer; the power circuit is used for supplying power to the detection module, the AD conversion module, the control module and the buzzer. The electric leakage detection device of the washing machine can be used for immediately detecting whether the electricity which leaks in the washing process of clothes exceeds the safety of the human body, and making a reminding sound, so that the life safety of a user can be well prevented from being threatened by electric leakage.

Description

technical field [0001] The invention belongs to the field of household appliances, and in particular relates to a washing machine leakage detection device. Background technique [0002] With the development of science and technology, washing machines have become a very common household appliance; washing machines are prone to leakage as they are used for a long time. Once leakage occurs, it will greatly endanger the life safety of users. Existing washing machines are grounded through the three-point board to prevent leakage. However, the ground wires of many three-point boards are not grounded at all, or the ground wire is broken, which is difficult to find. The role of anti-leakage. Contents of the invention [0003] The purpose of the invention is to overcome the problem that the current washing machine cannot detect whether electric leakage occurs. [0004] For this reason, the present invention provides a kind of electric leakage detection device of washing machine,...
