Abstract

The invention provides a gas water heater control method and device and a gas water heater. The method comprises the steps that the working state and the water outlet temperature of a section valve in the gas water heater are monitored; whether the switching condition of the working state of the section valve in a preset duration before the current moment meets a preset section valve switching requirement or not; if yes, the section valve is controlled to maintain the current working state; and a proportional valve in the gas water heater is adjusted based on preset water outlet temperature requirement and the current water outlet temperature, so that the water outlet temperature of the gas water heater meets the preset water outlet temperature requirement. Therefore, by maintaining the current working state of the section valve unchanged, the gas water heater carries out combustion with a fixed fire row number, and by controlling the proportional valve to adjust the outlet water temperature, outlet water temperature fluctuation caused by frequent switching of the section valve when gas changes is avoided, it is guaranteed that the outlet water temperature approaches to the temperature set by a user, the constant-temperature effect can be maintained without additional constant-temperature assistance, and the use experience of the user is guaranteed.

Description

Technical field [0001] The present invention relates to the field of household appliance technology, and more particularly to a gas water heater control method, a device, and a gas water heater. Background technique [0002] Gas water heaters are now generally used, and the constant temperature effect on gas water heaters is the most concerned experience of users. Although the existing gas water heater control method can achieve a good constant temperature effect in most cases, it encounters gas in gas water heaters. When a variety of gas change or gas constability, the existing gas water heater control method will frequently switch the segmented valve of the gas water heater under these special combustion conditions, which in turn leads to fluctuating the water temperature and cannot achieve the constant temperature effect. , Affect the user's experience. Inventive content [0003] In view of this, embodiments of the present invention provide a gas water heater control method, ...
