Full-automatic electric-heating water boiler control device

Abstract

The invention discloses a full-automatic electric-heating water boiler control device. The full-automatic electric-heating water boiler control device comprises a high water level probe point a, a low water level probe point b, a heating pipe, a high water level probe point c, a low water level probe point d, a heat-preservation heating pipe and a circuit board; the high water level probe point a, the low water level probe point b and the heating pipe are arranged in a cold water tank; the high water level probe point c, the low water level probe point d and the heat-preservation heating pipe are arranged in a hot water tank; an electromagnetic valve and a UV (ultraviolet) sterilizing lamp are mounted on a water inlet pipe of the cold water tank; the circuit board consists of a bridge circuit, a voltage stabilizing circuit, a differential voltage amplifying circuit, an RC filter circuit, an NE555 eight-pin time-base integrated circuit and a sampling input end; the sampling input end is correspondingly connected with the high water level probe point a, the low water level probe point b, the high water level probe point c and the low water level probe point d; three relays arranged on the circuit board controls the electromagnetic valve, the UV sterilizing lamp, the heating pipe and the heat-preservation heating pipe respectively. The full-automatic electric-heating water boiler control device is simple and practical, stable and reliable in control circuit, low in cost of electrical components, and convenient to maintain and replace; automatic water boiling of an electric-heating water boiler is realized, and clean and sanitary drinking hot water can be provided uninterruptedly.

Description

technical field [0001] The invention relates to an automatic control device, in particular to a fully automatic electric water boiler control device. Background technique [0002] Generally, the electric water boiler has only one water tank, and the control part is mainly composed of an upper limit, a middle limit, a lower limit, a heating tube and a float switch. When the water level reaches the lower limit, the float switch is connected, and the heater starts to heat the water in the water tank. The solenoid valve continues to inject water until the upper limit is reached, the solenoid valve is closed to stop water injection, and the electric heating tube stops heating; at this time, if someone releases water and the water level is lower than the middle limit, the solenoid valve will refill water and repeat the above process. This water boiler mixes hot and cold water, making it easy to drink raw and cold water. An electric water boiler with a heating tank, a cold water ...

AI Technical Summary

Problems solved by technology

In the case of hard water, this results in scaling of the water as it is heated, causing physical discomfort to the drinker

Electric water boilers are used in some environments with poor water quality. If the water is not filtered, the boiling water will contain certain impurities, which will affect the drinking taste
