Abstract

The invention discloses an electric water heater with a water outlet failure function. The electric water heater comprises an electric leakage protection plug, a main control board, a water flow sensor, a temperature sensor, an electric heating pipe and a display assembly, wherein the electric leakage protection plug is electrically connected with the main control board; the temperature sensor, the display assembly and the electric heating pipe are respectively electrically connected with the main control board; the water flow sensor is connected to the electric leakage protection plug for detecting the water-carrying capacity of the electric water heater and sending a detection signal to the leakage protection plug in real time; and the leakage protection plug is connected with a power supply and used for controlling the connection and disconnection of the power supply according to the detection signal of the water flow sensor. When a user uses hot water, the water flow transmits a signal to the electric leakage protection plug through the water flow sensor, the electric leakage protection plug controls a power supply zero line and a power supply live line to be simultaneously disconnected, the display assembly of the electric water heater and other working electric devices are synchronously extinguished, and the safety purpose of water outlet and power failure is achieved.

Description

technical field [0001] The invention belongs to the technical field of safety protection, and in particular relates to an electric water heater with the function of water outlet and power interruption. 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 function of water outlet and power cutoff appears in the prior art, that is, when the electric water heater is out of water, the power supply of the electric water heater is automatically cut off. When this function is realized, it is necessary to use a water flow sensor to detect whether the electric water heater is ...
