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

A semiconductor or light energy heating blow-molding water tank electric water heater having a water flow sensor is provided. A water tank (8) is manufactured by non -metallic material via a blowing technology and equipped with a water flow sensor (4) on a water intake pipe; the water flow sensor (4) is formed by an A part and a B part; for the A part, when water flows, the water flow pushes an impeller or a rotor or a Hall element (4-8) to rotate; a pulse signal or current or voltage signals can be output upon sensing water flows, and then a mediate relay can be actuated and a circuit is connected, and one or a plurality of electric-heating pipes can be connected and work; for the B part, a transverse through hole is formed in a small end of a piston (4-9); a through hole is also formed in the middle of the piston; upon water inflowing, water passes through the transverse hole and enters the water tank via the hole in the middle of the piston (4-9); water cannot be blocked when water flows in; when the water tank is filled with water or water inflow exceeds water outflow, internal pressure of the water increases and backpressure is produced in a large end of the piston (4-9), so the piston displaces; and a water inlet (4-11) is turned down or closed, so pressure of the water tank can be automatically adjusted.

Description

technical field [0001] The invention relates to a semiconductor or light energy heating blow 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 the improvement, it is a semiconductor or light energy heating blow molding water tank electric water heater with a water flow ...
