A method for controlling a water proportional valve of a gas water heater

Abstract

The invention discloses a gas water heater water proportional valve control method. The method is characterized is that a gas proportional valve used for changing the gas inlet amount of a gas water heater, a sectioning valve used for changing fire of the gas water heater, a water proportional valve used for changing the water inlet amount of the gas water heater, and a controller connected with the gas proportional valve, the sectioning valve and the water proportional valve are included; the controller automatically judges whether a set temperature value can be reached in set time in the combusting state with the maximum load according to the set temperature and the maximum water inlet amount; if yes, a motor of the water proportional valve is controlled to close; and if not, the action of the motor of the water proportional valve is controlled to reduce the water inlet amount of the gas water heater. Through the method, the heating time of the gas water heater can be shortened, the water amount can be automatically controlled in the bath process conveniently, operation is simple and convenient, and the adaptability and using comfort of the whole heater are improved.

Description

technical field [0001] The invention relates to the technical field of gas water heater control, in particular to a method for controlling a water proportional valve of a gas water heater. Background technique [0002] As a household appliance for bathing, a gas water heater supplies users with hot water for bathing and other water needs. When the temperature is too high or too low compared to the set temperature, and the gas volume adjustment of the gas proportional valve cannot meet people's needs, people can adjust the size by setting the size. The water adjustment knob adjusts the water output, but it is limited to the manual adjustment method, which is inconvenient to control the size of the water flow. [0003] In order to solve the above technical problems, the water proportional valve device is installed to automatically adjust the water volume, so as to meet the needs of users with different water volumes and different temperatures, and the adaptability and comfort ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to address the deficiencies in the prior art, and propose a method for controlling the water proportional valve of a gas water heater, which solves the inconvenience of manual adjustment by people and the problem of hot and cold water adjustment in the existing part of the control method, and can conveniently The water volume is automatically controlled during the bathing process, which is easy to operate and improves the adaptability and comfort of the whole machine
