Multifunctional reversible water storage electric water heater

Abstract

The invention discloses a multifunctional reversible water storage electric water heater which comprises a shell and a liner arranged in the shell. The multifunctional reversible water storage electric water heater is characterized by further comprising an electromagnetic controller, a display screen, a universal change-over switch and two electromagnetic generators, wherein the electromagnetic controller, the display screen and the universal change-over switch are embedded into the shell, the two electromagnetic generators are located at the bottoms of the left end and the right end of the liner, a water insulation sliding screen is arranged in the liner to divide the liner into a left liner cavity and a right liner cavity, the exterior of the universal change-over switch is provided with a cold water inlet and a hot water outlet, two cold and hot water pipes are arranged in the universal change-over switch and connected to the left end and the right end of the liner respectively, the universal change-over switch is provided with a zero-gear switch, a first-gear switch and a second-gear switch, and the left end and the right end of the liner are provided with two air one-way valves and reducing valves which are each connected with a ventilation pipe extending out of the shell. The multifunctional reversible water storage electric water heater has the advantages of being reasonable in structural design, safe, reliable, strong in function, economical, practical, high in heat efficiency and utilization rate and the like.

Description

technical field [0001] The invention relates to a water heater, in particular to a multifunctional reversible water storage electric water heater. Background technique [0002] Looking at the heating methods of all water heaters on the market at present, there are no more than four forms, namely gas heating type, resistance heating tube type, solar energy conversion heating type and air energy conversion heating type. The functions of the four water heaters have their own characteristics. However, both the gas type and the resistance tube type have certain risks, while the solar type and the air type have certain limitations. , solar heating is limited. In winter, the air energy heating effect is also limited when the air temperature is low.

AI Technical Summary

Problems solved by technology

The functions of the four water heaters have their own characteristics. However, both the gas type and the resistance tube type have certain risks, while the solar type and the air type have certain limitations. , limited solar heating

In winter, when the air temperature is low, the heating effect of the air energy is also limited

However, these types of water heaters have low thermal efficiency utilization of gas and water storage water heaters, especially water storage water heaters, which are only about 50% (because it can only press out hot water by filling cold water, including Air energy water heater, which is determined by its working principle)

Especially in winter, its thermal efficiency is lower. In addition, the function of this type of water heater is too single, and dirt is easy to form in the water tank, which affects the use effect.
