Abstract

An electric water heater with an external light wave heating non-metallic blow molding water tank with a decompression water flow sensor. The water tank 8 is made of non-metal material blow molding technology, and a water flow sensor 4 with a decompression function is installed on the water inlet pipeline of the water tank. It consists of two parts A and B: part A, when water flows, 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 middle The relay pulls in and the circuit is turned on. 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 the water is in the water, it does not block the entry of water. When the water tank is filled with water or the water intake is greater than the water output, when the pressure in the water tank increases, the large end of the piston 4-9 will generate a back pressure, which will cause the piston to displace, turn down or even close the water inlet. 4-11. The heating method is to install the halogen or carbon fiber electric heating tube in the air in the stainless steel casing.

Description

technical field [0001] The invention relates to an electric water heater with an external light wave heating non-metallic blow molding water tank 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 non-metal material injection molding process to make the water tank. The improved water heater is an ex...
