Problems solved by technology

[0002] At present, all household electric water heaters in the world, the water inlet pipe is connected to the water source, from the water inlet to the water tank, without installing other components, can not automatically adjust the pressure in the water tank, all adopt a pressure-bearing structure, and the rated pressure is generally 0.6 Mpa, the test pressure is 1.2Mpa; this kind of pressure will cause many difficult problems; for example, the heat expansion and contraction water tank will crack, leak, and explode under pressure, which is a problem in the world

Abstract

The invention discloses a semiconductor or light energy heating injection water tank electric water heater with a water flow sensor, wherein the water tank 8 is made by injection molding technology of nonmetallic materials, and a water flow sensor 4 is equipped on a water inlet pipeline of the water tank. The water tank comprises two parts: part A has a structure that when water flows, the water flow pushes an impeller or rotor or Hall element 4-8 rotate, and a pulse signal or a current or a voltage signal is output by sensing the water flow, making a middle relay pulled and a circuit conducted, and one or more heater pipes powered on; part B has a structure that a transversal thorough hole is provided in a small end and a through hole is provided in the center of a piston 4-9, so that when water is supplied, the water flows from the center hole of the piston 4-9 into the water tank through the transversal hole, and the water flows in smoothly; when the water tank is full of water or the water inlet volume is larger than the water outlet volume, and the pressure inside the water tank is increased, a back pressure is generated at a large end of the piston 4-9, making the piston displaced, and a water inlet 4-11 is turned smaller or turned off.

Description

technical field [0001] The invention relates to a semiconductor or light energy heating injection molding water tank electric water heater with a water flow sensor. Background technique [0002] At present, all household electric water heaters in the world, the water inlet pipe is connected to the water source, from the water inlet to the water tank, without installing other components, can not automatically adjust the pressure in the water tank, all adopt a pressure-bearing structure, and the rated pressure is generally 0.6 Mpa, the test pressure is 1.2Mpa; this pressure will cause many difficult problems; for example, the heat expansion and contraction water tank will crack, leak, and explode under pressure, which is a problem in the world. Contents of the invention [0003] The present invention improves the existing electric water heater, and after improvement, it is a semiconductor or light energy heating injection water tank electric water heater with a water flow se...
