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

The invention relates to a semiconductor with a water flow sensor or an electric water heater with a light-energy heating metal water tank. The water tank 8 is made by metal material and provided with the water flow sensor 4 with a pressure reduction function on a water inlet pipeline of the water tank. The water flow sensor is composed of two parts including an A part and a B part. The A part is characterized in that when water flows, water flows push an impeller or a rotor or Hall elements 4-8 to rotate; and by induction of water flows, a pulse signal is emitted or signals such as current or voltage are outputted such that a middle relay is absorbed, a circuit is conducted and one or multiple groups of electric heating pipes is/are electrified for work. The B part is characterized in that small ends of pistons 4-9 have transverse through holes; the middles have through holes; when water enters, water passes through the transverse holes and enters the water tank through the pistons 4-9; when entering, water is not blocked; when the water tank is filled with water or water inflow is larger than water yield, pressure of the water tank is on the increase, large ends of the pistons 4-9 generate back pressure such that displacement of the pistons is achieved; and water inlets 4-11 are turned down or even closed.
Description
technical field [0001] The invention relates to a semiconductor or light energy heating metal 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 heaters made of metal materials for water tanks. The improved electric water heaters are semi-conductor or light energy heating metal water tanks with w...
