External fast-heating electric water heater for water switch semiconductor or light energy heating injection water tank

Abstract

The invention discloses an external fast-heating electric water heater for a water switch semiconductor or a light energy heating injection water tank, wherein the water tank 8 is made by injection molding technology of nonmetallic materials; a water switch 4 with decompression function is equipped on a water inlet pipeline of the water tank; the water tank 8 comprises two parts, part A has a structure that channels of an internal inlet and an outlet of a main body 4-1 are not directly communicated but separated by a cover plate 4-2, so when water flows, the water pushes the cover plate 4-2 positively, and promotes a dynamic contact 4-9 and a static contact 4-8 contact or make a micro-move switch 4-7 communicated and a circuit powered on; part B has a structure that a small end of a piston 4-12 has a transversal thorough hole and the center of the piston 4-12 has a hole, so that when water is supplied, the water flows from the center hole of the piston 4-12 through the transversal hole into the water tank; when pressure in the water tank is increased, a back pressure is generated at a large end of the piston 4-12, making the piston 4-12 displaced, and an inlet 4-14 is turned smaller or closed.

Description

technical field [0001] The invention relates to a water switch semiconductor or a light energy heating injection molding water tank with an external fast heating electric water heater. 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 tanks are all pressure-bearing structures with a rated pressure of 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 that uses metal materials to make water tanks. After the improvement, it is a water switch semiconductor or ligh...
