Electric water heater for separating cold and hot water

Abstract

The invention discloses an electric water heater for separating cold water and hot water. The electric water heater for separating cold water and hot water is characterized by comprising an external cylinder, an internal cylinder I and an internal cylinder body II, a a pressure storage chamber and an electromagnetic valve I, wherein the internal cylinder I and the internal cylinder body II are mounted in the external cylinder body; the pressure storage chamber is arranged above the external cylinder body; the electromagnetic valve I is arranged under the external cylinder body; the electromagnetic valve I is respectively connected with the internal cylinder I and the internal cylinder body II through a water feeding pipe I and a water feeding pipe II; the internal cylinder I and the internal cylinder body II are correspondingly connected with two-position two-way electromagnetic valves II used for controlling hot water to be drained through a water outlet pipe I and a water outlet pipeII; and water outlets of the electromagnetic valves II are connected with a water mixing valve. The electric water heater for separating cold water and hot water has the advantages that the structureis simple; by using a cold and hot water separating technology, the water temperature is constant during using; the hot water is drained under a condition of absolute power failure; the use is safer;and by using a physical dry burning preventing scheme, dry burning of a heating tube is effectively avoided.

Description

technical field [0001] The invention relates to an electric water heater, in particular to a closed storage type electric water heater with cold and hot water separated. Background technique [0002] A water heater refers to a device that raises the temperature of cold water into hot water within a certain period of time through various physical principles. According to different principles, it can be divided into electric water heaters, gas water heaters, solar water heaters, magnetic energy water heaters, air energy water heaters, heating water heaters, etc. An electric water heater refers to a water heater that uses electricity as an energy source for heating. According to the heating power, electric water heaters can be divided into three types: water storage type (also known as volumetric or heat storage type), instant heating type, and rapid heating type (also known as semi-water storage type). Compared with the instantaneous and rapid heating electric water heaters,...

AI Technical Summary

Problems solved by technology

However, the current closed-type water storage electric water heaters use heating and water injection in the same cylinder, and inject cold water while discharging hot water. The risk of leakage is high, and the water temperature in the cylinder fluctuates greatly. Therefore, there is an urgent need for a cold and hot water separation system. , constant water temperature, safe household closed water storage electric water heater
