Abstract

The invention discloses a light wave heating metallic water tank electric water heater provided with a water flow switch with a pressure reducing function. A water tank 8 is made from a metallic material, and the water flow switch 4 with the pressure reducing function is installed on a water inlet pipeline of the water tank. The water flow switch is composed of an assembly A and an assembly B. As for the assembly A, in a main body 4-1, a water inlet channel and a water outlet channel are separated by a cover plate 4-2; when water flows, the water compulsively pushes the cover plate 4-2 and enables a movable contact 4-9 and a stationary contact 4-8 to make contact or enables a microswitch 4-7 to be switched on, so that circuits are closed. As for the assembly 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 flows in, the water passes through the transverse hole and enters the water tank through the middle hole of the piston 4-12; and when the pressure in the water tank is increased, backpressure is generated at the big end of the piston 4-12, so that the piston 4-12 is moved to turn down or even close a water inlet 4-14. The heating mode that a light wave heating halogen electric heating tube or a light wave heating carbon fiber electric heating tube is installed in air in a stainless steel casing pipe is adopted, and water-jacket heating is achieved.

Description

technical field [0001] The invention relates to an electric water heater with a light wave heating metal blow molding water tank equipped with a water flow switch 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, the water tank is a pressure-bearing structure, and the rated pressure is generally The test pressure is 0.6Mpa, and 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 materials. After the improvement, it is ...
