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

Abstract

An electric water heater based on large volume of room-temperature water consists of central control circuit, water flow switch, water pump, heater, water level transducer, temperature transducer, electrically operated valve, electrically operated three-way valve, keyboard circuit and display circuit. It is featured as utilizing heat conduction principle to heat running water in large capacity of water container up to room temperature by ambient temperature then heating room temperature water by electric heater for providing hot water so as to save energy.

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...
