Water temperature automatic control circuit for temperature constant water heater

Abstract

The invention discloses a water temperature automatic control circuit for a temperature constant water heater. The water temperature automatic control circuit for the temperature constant water heater comprises an electric heater power supply circuit, a voltage transformation rectifying voltage stabilizing circuit, a display circuit, a mini-type electric water valve circuit, a trigger circuit , a microcomputer chip and a control signal transmission circuit. According to the water temperature automatic control circuit for the temperature constant water heater, the microcomputer chip control technology is adopted, the output power can be adjusted at any time according to dynamic data of the in-out water temperature and the setting temperature, and the water volume is adjusted through a mini-type water valve motor, so that the effect of enabling the effluent water temperature to be constant at any time is achieved and even in winter, when the water volume is large and the water temperature is low, the water heater can automatically adjust the water volume to achieve constant temperature and achieve the effect of being good in utilization comfort of bath and sanitary water.

Description

technical field [0001] The invention relates to a water temperature automatic control circuit of a constant temperature water heater, which belongs to the technical field of daily household appliances. Background technique [0002] With the improvement of the quality of modern life, people have higher and higher requirements for the comfort of bathing and sanitary hot water. Especially for the hot water for bathing and sanitation in modern families, people hope that it can be heated immediately after the water is turned on. Satisfy continuous multi-person bathing. In order to quickly obtain constant temperature and comfortable hot water, the key lies in the precise adjustment of the outlet water temperature of the electric water heater. According to the dynamic data such as voltage, water inlet volume, inlet water temperature, and outlet water temperature, advanced control technology is adopted to achieve the effect of constant outlet water temperature. Bathing comfort is ...

AI Technical Summary

Problems solved by technology

However, when the water volume is large and the water temperature is low in winter, the power of the water heater is the largest and the water temperature cannot reach the set temperature, and the water heater cannot adjust the water volume to achieve a constant temperature.
