Photoelectron-heating non-metal blow molding water tank electric water heater with water flow switch with pressure reduction function

Abstract

Disclosed is a photoelectron-heating non-metal blow molding water tank electric water heater with a water flow switch with a pressure reduction function. A water tank (8) is made of non-metal materials through blow molding, and the water flow switch (4) with the pressure reduction function is mounted on a water inlet pipeline of the water tank and is composed of a part A and a part B; according to the part A, a water inlet channel and a water outlet channel in a main body (4-1) are not directly communicated and are separated by a cover plate (4-2); when water flows, the water will push the cover plate (4-2) in a forcing manner, enables a movable contact (4-9) and a static contact (4-8) to make contact or enables a microswitch (4-7) to be switched on; and according to the part B, a transverse through hole is formed in the small end of a piston (4-12), a hole is also formed in the middle of the piston (4-12), when water enters, the water passes through the transverse hole, and enters the water tank from the middle hole of the piston (4-12), and when the pressure in the water tank is increased, the large end of the piston (4-12) generates backpressure, the piston (4-12) displaces, and a water inlet (4-14) is turned down and even closed. According to a heating manner, photoelectron heating halogen or carbon fiber electric heating pipes are contained in air in a stainless steel casing pipe.

Description

Technical field [0001] The invention relates to an electric water heater equipped with a light wave heating non-metal blow molding water tank equipped with a water flow switch with a pressure reducing function. Background technique [0002] At present, all domestic electric water heaters in the world have the water inlet pipe connected to the water source. From the water inlet to the water tank, the pressure in the water tank cannot be automatically adjusted without installing other components. The water tank adopts a pressure-bearing structure, and the rated pressure is generally 0.6Mpa, the test pressure is 1.2Mpa; this pressure will have many difficult problems; for example, thermal expansion and cold shrinkage tanks will crack, leak, and explode under pressure, which is a world problem. Summary of the invention [0003] The present invention improves the existing water tank electric water heater made of metal materials. After the improvement, it is a light wave heating non-met...
