Problems solved by technology
Since the sources of gas supplied to gas water heaters tend to be diversified, and the composition of gas varies greatly, it is easy to cause technical problems such as incomplete combustion of water heaters, vibration combustion and high exhaust gas emission rate.
At the same time, there will be slight differences in the structural elements of multiple gas water heaters of the same model, so that the working data detected by the gas water heaters will also be different. Therefore, the control accuracy of the gas water heaters in the related art is relatively poor.

The invention discloses a gas water heater and a control method thereof. The control method of the gas water heater comprises the steps of obtaining a correction hot water yield according to an automatic sampling instruction, wherein the correction hot water yield is determined by the water inlet temperature, the water outlet temperature and the water flow rate of the gas water heater; according to the current water inlet temperature of the gas water heater, the current water outlet temperature of the gas water heater and the current water flow rate of the gas water heater, determining the current hot water yield of the gas water heater; calculating the difference between the correction hot water yield of the gas water heater and the current hot water yield of the gas water heater, and controlling the opening degree of a gas proportional valve of the gas water heater according to the difference. According to the control method of the gas water heater, the control precision of the gas water heater can be improved, combustion of the gas water heater can be more sufficient, the heat production efficiency is high, the produced waste gas amount is small, and the operation safety is high.
Description
technical field [0001] The present invention relates to the technical field of water heaters, and more specifically, to a control method of a gas water heater and a gas water heater. Background technique [0002] In related technologies, gas water heaters use gas as fuel, and the combustion heat required by the gas water heater for water supply is controlled by controlling the flow of gas flowing into the gas water heater. Since the sources of gas supplied to gas water heaters tend to be diversified, and the composition of gas varies greatly, it is easy to cause technical problems such as incomplete combustion of water heaters, vibration combustion and high exhaust gas emission rate. At the same time, the structural elements of multiple gas water heaters of the same model also have slight differences, so that the working data detected by the gas water heaters will also be different. Therefore, the control accuracy of the gas water heaters in the related art is relatively poo...
