Abstract

The invention discloses an earth leakage protection system for an electric water heater. The earth leakage protection system comprises a control system, a temperature sensor, a display and an earth leakage protection plug, wherein the temperature sensor, the display and the earth leakage protection plug are connected with the control system; and the control system is used for processing a signal fed back by the temperature sensor and displaying the signal on the display. The earth leakage protection system is characterized in that a water current detecting device and a power supply module are also connected onto the control system; the control system controls the on / off of the earth leakage protection plug according to a water current signal fed back by the water current detecting device; and the power supply module supplies power to the control system and the display. Compared with the prior art, the earth leakage protection system disclosed by the invention has the advantages that whether the electric water heater is energized or not, the water using behavior of users can be perceived, water-outlet outage and three-pole (zero line, fire wire and earth wire) breaking of the electric water heater are completely realized, and further safe bathing is realized; after outage, the temperature of an inner container is displayed by a digital tube; and after water use is ended, energization is automatically performed. The invention also provides the electric water heater.

Description

technical field [0001] The invention relates to electric water heater safety protection technology, in particular to an electric water heater leakage protection system and the electric water heater. Background technique [0002] An electric water heater is a water heater that uses electricity as energy for heating. In order to ensure the safety of use, the electric water heater is usually connected with a leakage protection system to realize the power outage of the water outlet. [0003] A Chinese invention patent with a publication number of CN204329335U discloses an electric water heater with a water outlet power-off protection device, including a casing, a heating pipe, a controller, an inner tank, an electric leakage protector, and a thermal circuit breaker. The casing is provided with a water inlet pipe and an outlet. The water pipe is characterized in that: the water inlet pipe is provided with a water flow sensor, the water flow sensor is electrically connected to th...
