Abstract

The invention discloses an electric leakage protector, and relates to the technical field of safety protection. The electric leakage protector comprises a controller, an automatic power-off control module, a power-off / power-on execution driving module and a contact detection circuit, wherein the controller, the automatic power-off control module and the power-off / power-on execution driving module are connected in sequence; the power-off / power-on execution driving module is in contact connection with a power supply; and the contact detection circuit is connected with the controller. According to the electric leakage protector, the contact detection circuit is adopted for detecting on-off conditions of the contact of the power supply, and the on-off conditions are fed back to the controller so as to realize self examination of the on-off conditions, so that potential safety hazards caused by primary power outage failure due to potential failure of electronic elements or abrasion of an execution mechanism are avoided, thereby further improving safety.

Description

technical field [0001] The invention relates to the technical field of safety protection, in particular to a leakage protector. Background technique [0002] An electric water heater refers to a water heater that uses electricity as an energy source for heating. It is one of the three major water heaters juxtaposed with gas water heaters and solar water heaters. After more than ten years of development, electric water heaters have continued to improve in technology and are increasingly favored by consumers. [0003] In order to improve the safety performance of electric water heaters, the water outlet power cut-off function is proposed. Therefore, it is often necessary to realize the power-on and power-off functions. In the prior art, the automatic power-on and automatic power-off control leakage protectors all adopt a combination of electronics and machinery. In the control mode, the electronic controller is responsible for receiving and issuing instructions, and the mecha...
