Multifunctional energy-saving electric heater

Abstract

The invention is a multifunctional energy-conserving electric water heater, using the heat exchange principle, and able to meet the different demands on hot boiled water, cold boiled water and living hot water. It mainly includes hot boiled water tank, cold boiled water tank, living hot water tank, heat exchange coiled pipe, reheater coiled pipe, electric heater and valve. The living hot water tank is situated between the other two water tanks, and has an independent heater; the hot boiled water tank is smaller and situated over the living hot water tank, also has an independent heater, is connected with the cold boiled water tank through the heat exchange coiled pipe, and controls the hot boiled to enter the cold boiled water tank by a temperature control valve on the heat exchange coiled pipe; the cold boiled water tank is situated at the bottom and holds the reheater coiled pipe, and can preheat the running water entering by the reheater coiled pipe. It can flexibly be used according to practical conditions. It has strong flexibility, saves energy source, specially applied to dorms, homes and other places; and has very good economic and social benefits.

Description

technical field [0001] The invention relates to a multifunctional energy-saving electric water heater, in particular to an electric water heater capable of satisfying demands for hot boiled water, cold boiled water and domestic water at the same time through the principle of heat exchange. The utility model belongs to the technical field of household appliances. Background technique [0002] Electric water heaters are often used in our daily life, especially in public places, and electric water heaters are inseparable. Generally speaking, electric water heaters must not only meet the supply of boiling water, but also meet the requirements of domestic water. In this case, when you need to drink boiled water, you need to wait for a long time, and after heating a lot of boiled water, you often only need a small part of boiled water. When domestic hot water is not needed, most of the boiled water may be wasted; Domestic water is needed, and boiled water and cold water need to b...
