Problems solved by technology

Instantaneous electric water heaters are expensive and use a lot of power, and ordinary residential wires cannot afford them.
Thermal storage electric water heaters are relatively cheap and have low power. Before use, they must be heated for a long time to reach a higher temperature (usually around 70°C), and then mixed with cold water to achieve a suitable water bath temperature. The biggest disadvantage is that it is easy to generate scale, which increases energy consumption and shortens the life of the water heater

Embodiment Construction

[0012] from figure 1 It can be seen that the present invention includes a water storage bucket 1, a heating pipe 2, and a water inlet pipe 3, wherein the water storage bucket 1 has a thermal insulation piston 5, which divides the inner cavity of the water storage bucket 1 into a hot water cavity 11 and a cold water cavity 12. There is a cold water inlet hole 61 and two symmetrically distributed balance holes 71 on the hot piston 5. The center of the heat insulating piston 5 is a depression 52, and the cold water inlet hole 61 is located in the center of the bottom of the depression 52. Controlled by a central valve 6 , a boss 51 is provided at the bottom of the concave 52 on the periphery of the cold water inlet hole 61 , and the boss is provided with a number of water inlet holes 53 in the radial direction. The closing and opening of the balance hole 71 is controlled by the corresponding balance valve 7 , and the pressure difference between the cold and hot water chambers is ...

Abstract

The invention discloses an electric water heater comprising a water barrel, a heating tube and a water inlet tube. The inner cavity of the water barrel is divided into a cold water cavity and a hot water cavity by an insulating piston; the insulating piston is provided with a cold water inlet hole in the center and balance holes by the side, wherein the cold water inlet hole is controlled by a central valve to open and close, and the balance holes are controlled by corresponding balance valves to open and close; the heating tube is arranged in the hot water cavity of the water barrel, and the periphery of the heating tube is provided with a telescopic cylinder arranged on the insulating piston; and both the upper end part and the lower end part of the inner cavity of the telescopic cylinder are communicated with the hot water cavity. After being preheated and then deenergized, the electric water heater can keep the temperature of hot water constant and uniform; in addition, when in use, the electric water heater can avoid water scale generation; the electric water heater has the functions of an instant heating type and a heat preservation type and is provided with a water quantity indicating piece capable of indicating left hot water quantity.

Description

technical field [0001] The present invention relates to an electric water heater. Background technique [0002] Now more and more people choose to use electric water heaters, because electric water heaters are easy to install and easy to use. Electric water heaters are divided into two types: instantaneous and thermal storage. Instantaneous electric water heaters are expensive and use a lot of power, which cannot be carried by ordinary residential wires. The thermal storage electric water heater has a low price and low power. It must be heated for a long time before use to reach a higher temperature (usually about 70 ° C), and then mixed with cold water to achieve a suitable water bath temperature. The biggest drawback is that it is easy to produce scale, which increases energy consumption and shortens the life of the water heater. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide an electric water heater which is not easy to produce s...
