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 provides an external optical wave heating metal water tank electric water heater provided with a water flow sensor with a pressure reduction function. A water tank 8 is made of metal materials. The water flow sensor 4 with the pressure reduction function is installed on a water inlet pipeline of the water tank. The water flow sensor is composed of a component A and a component B. According to the component A, a water inlet channel and a water outlet channel are separated by a cover plate 4-2 instead of communicating with each other directly in a main body 4-1; when water flows, the cover plate 4-2 is forcibly pushed by water, so that a movable contact 4-9 and a stationary contact 4-8 are made to make contact or a microswitch 4-7 is made to be turned on. According to the component B, a transverse through hole is formed in the small end of a piston 4-12, and a hole is further formed in the middle of the piston 4-12; when water inflows, water passes through the transverse through hole and then enters the water tank through the middle hole of the piston 4-12; and when the pressure in the water tank is increased, back pressure is generated by the big end of the piston 4-12, displacement of the piston 4-12 occurs, and thus the area of a water inlet 4-14 is decreased or even the water inlet 4-14 is closed.

Description

technical field [0001] The invention relates to an electric water heater with an external light wave heating metal water tank equipped with a water flow sensor with a decompression function. 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 with a water tank made of metal material. After the improvement, it is an external light wave heating metal...
