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, the water tank is a pressure-bearing structure, and the rated pressure is generally 0.6Mpa, the test pressure is 1.2Mpa; this kind of pressure will cause many difficult problems; for example, the water tank that expands with heat and shrinks with cold will crack, leak, and explode under pressure, which is a problem in the world

Embodiment Construction

[0015] Attached below Figures 1 to 10 In the accompanying drawings: housing 1, cold water inlet pipe 2, hot water outlet pipe 3, water flow switch 4 with decompression function, controller 5, electric heating tube 6 (semiconductor or photoelectric heating tube 6- 1. Metal electric heating tube 6-2), fixed point 7, water tank 8, faucet 9, temperature measuring or temperature limit switch installation pipe 10, flange 11, pressure relief valve 14, sewage outlet 15, water flowing through heating water device 16 , metal or non-metal casing 17, water 19.

[0016] figure 1 , Fig. 3 to Fig. 5 are the water flow switch 4 with decompression function, are made up of A, B two parts:

[0017] In part A, the water inlet and outlet channels in the main body 4-1 are not directly connected, but are separated by the cover plate 4-2. When there is water flowing, the water will forcefully push the cover plate 4-2, and at the same time push the seal 4 -3 and the pusher 4-4, and make the movabl...

Abstract

The invention discloses an external semiconductor or light energy heating metal water tank electric water heater with a water flow switch. A water tank 8 is made of a metal material; the water flow switch 4 is mounted on a water inlet pipeline of the water tank and consists of two parts, namely a part A and a part B; in the part A and in a main body 4-1, a water inlet channel is separated from a water outlet channel through a cover plate 4-2; during flowing, water can push the cover plate 4-2 forcibly, simultaneously push a sealing piece 4-3 and a pushing piece 4-4, and enable a movable contact 4-9 to be in contact with a static contact 4-8 or switch on a micro-switch 4-7 to connect a circuit; in 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 centre of the piston 4-12; during water inflowing, water passes through the transverse through hole and enters into the water tank from the centre hole of the piston 4-12; during water inflowing, water is not prevented from entering; when the water tank is filled with water or the water inlet amount is greater than the water outlet amount and the pressure in the water tank is increased, the large end of the piston 4-12 produces back pressure, so that the piston 4-12 displaces so as to turn down or even close a water inlet 4-14.

Description

technical field [0001] The invention relates to an electric water heater with an external semiconductor or light energy heating metal 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 heater made of metal material for the water tank, and the improved electric water heater is an externa...
