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 non-metallic injection-molded water tank with a decompression water flow sensor is equipped with an external fast-heating electric water heater. The water tank 8 is made of a non-metallic material injection molding process, and a water flow sensor 4 with a decompression function is installed on the water inlet pipeline of the water tank. A and B are composed of two parts: Part A, when there is water flow, the water flow pushes the impeller or rotor or Hall element 4-8 to rotate, and outputs pulse signals or current, voltage and other signals through the induction of water flow, so that the intermediate relay Pull in, the circuit is turned on, and when the water is turned off, the circuit is disconnected. In part B, there is a horizontal through hole at the small end of the piston 4-9, and there is also a through hole in the middle. When water enters, the water passes through the horizontal hole and enters the water tank from the middle hole of the piston 4-9. When the pressure in the water tank increases, the piston 4 The big end of -9 produces back pressure, makes piston displacement, closes down or even closes water inlet 4-11; When discharging water, water inlet is opened repeatedly. At the same time, an external fast heating device 16 is installed in the outlet pipeline of the water tank 8 .

Description

technical field [0001] The invention relates to a non-metallic injection-molded water tank external fast heating electric water heater with a decompressed 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 that uses metal materials to make water tanks, and the improved electric water heater is a non-metallic injection-molded wat...
