Large capacity instant electric water heater for water in room temperature

Abstract

The invention is an open-type large-capacity room temperature water heater with automatic control and pressurization functions, that is, a thermoelectric water heater. It includes central control circuit, water flow switch S, water pump M, heater G, water level sensor H1, temperature sensor W, electric control valve Y1, three-way electric control valve Y, keyboard circuit and display circuit. The body does not have an insulation layer, and the principle of heat conduction is used in use to make the temperature of tap water stored in a large amount of water heater tanks rise to room temperature naturally by relying on the ambient temperature, and then on the basis of water storage at room temperature, instant electric heating provides hot water, thereby realizing energy saving. It also avoids the problem of heat loss that occurs during the storage of hot water in general electric water heaters.

Description

(1) Technical field [0001] The invention relates to an electric water heater, in particular to an open-type large-capacity room-temperature water heater, that is, a thermoelectric water heater with automatic control and pressurization functions. (2) Background technology [0002] At present, the closed electric water heaters that can be seen on the market are all heat preservation and preheating types. As long as this type of electric water heater is powered on, it will heat all the stored water at the tap water temperature in the tank, even if the user only needs a small amount of hot water. Cause regular and unnecessary waste of electric energy. Another serious shortcoming of the closed electric water heater is that it cannot work when the tap water is cut off or the tap water pressure is lower than 0.02MP. At present, some cities in my country have taken intermittent water supply (night water) and low-pressure water supply as a last resort due to severe water shortage. Im...

AI Technical Summary

Problems solved by technology

However, general electric water heaters cannot directly provide room temperature water without electric heating. Even if users need room temperature water, they must use electric heating to raise the cold tap water to room temperature water at about 22 degrees, and use electric heating to raise the water temperature by 13 degrees. But people don't need it, causing unnecessary waste of electricity
