Problems solved by technology

[0002] The existing central electric water heater is a device that centrally supplies hot water to the whole family or unit. The water inlet pipeline of the water tank is directly connected to the water source, and the water is sent into the water tank, which is called the water inlet pipeline. There are no other components on this pipeline. ;The water tank is made of metal, lined with enamel water tank, and stainless steel water tank, the rated pressure is 0.6mpa, and the test pressure is 1.2mpa. This kind of water tank will crack, leak and explode, and the service life is short

Abstract

The invention provides a central electric water heater with a pressure reduction function. A water tank 8 is made of non-metal materials through blow molding or injection molding or rotational molding, or the water tank 8 is made of metal materials. A water flow sensor or a water flow switch 4 with the pressure reduction function is installed on a water inlet pipeline of the water tank. Meanwhile, a closed or semi-open type instant flowing-water heating device 16 is installed in the water tank, and thus rapid heating can be achieved. In addition, a heating element is a metal electric heating tube or a non-metal halogen tube or a carbon fiber tube, and water-isolated heating is achieved.

Description

technical field [0001] The invention relates to a central electric water heater with decompression function. Background technique [0002] The existing central electric water heater is a device that centrally supplies hot water to the whole family or unit. The water inlet pipeline of the water tank is directly connected to the water source, and the water is sent into the water tank, which is called the water inlet pipeline. There are no other components on this pipeline. The water tank is based on metal, lined with enamel water tank, and stainless steel water tank, the rated pressure is 0.6mpa, and the test pressure is 1.2mpa. This kind of water tank will crack, leak and explode, and its life is short. Contents of the invention [0003] The present invention improves the existing central electric water heater. After the improvement, it becomes a central electric water heater with decompression function. , a water tank 8, a water nozzle 9, a flange 11, and a pressure relie...
