Abstract

The invention discloses an electric water heater provided with a water switch and a blow-molded water tank and adopting an external semiconductor or optical energy for heating. The water tank (8) is manufactured from non-metallic materials through an injection-molding process, and the water switch (4) is arranged on a water inlet pipeline of the water tank and 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 partitioned by a cover plate (4-2); and when water flows, the water pushes the cover plate (4-2), a sealing piece (4-3) and a pushing piece (4-4) at the same time in a forcing mode and enables a movable contact (4-9) to make contact with stationary contacts (4-8) or enables a microswitch (4-7) to be connected, so that a circuit is connected. According to the part B, a transverse through hole is formed in the small end of a piston (4-12), and a hole is also formed in the center of the piston (4-12); when entering, water passes through the transverse through hole and enters the water tank from the center hole of the piston (4-12), and the water is not stopped in the entering process; and when the water tank is full of water or the water inlet quantity is greater than the water outlet quantity, and the pressure in the water tank is increased, backpressure is generated at the big end of the piston (4-12), displacement of the piston (4-12) occurs, and a water inlet (4-14) is smaller in opening degree or even closed.

Description

technical field [0001] The invention relates to an electric water heater with an external semiconductor or light energy heating and blow molding water tank with a water flow switch. 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 heaters with metal materials to make water tanks. After the improvement, it is an electric ...
