The invention discloses a gas water heater and a control method thereof. The gas water heater comprises a combustion system, a draught fan, a wind pressure sensor component and a controller; the draught fan communicates with the combustion system; the wind pressure sensor component is used for obtaining the current wind pressure generated by the draught fan; and the controller is connected with the wind pressure sensor component and is used for controlling the combustion heat power size of the combustion system according to the current gas intake quantity, controlled by the wind pressure, of the combustion system. The control method of the gas water heater comprises the following steps: obtaining the current wind pressure generated by the draught fan; and controlling the gas intake quantity of the combustion system according to the current wind pressure to control the combustion heat power size of the combustion system. As the current wind pressure generated by the draught fan varies,the combustion heat power size of the combustion system also varies, so that the situation that the current wind pressure of the draught fan cannot meet the wind pressure requirement of the combustionsystem is avoided, and the probability of occurrence that the gas water heater is unstable in combustion, the exhaust gas exceeds the standard, and combustion vibration occurs is effectively reduced.
Description
technical field [0001] The invention relates to the field of water heaters, in particular to a gas water heater and a control method thereof. Background technique [0002] The gas water heater of related art is provided with blower fan. When the gas water heater is working, the fan can provide oxygen to the gas water heater, so that the gas water heater can work normally. However, the speed of the fan is constant or fixed at several speeds, so the current wind pressure generated by the fan may not meet the wind pressure requirements of the combustion system, resulting in unstable combustion of the gas water heater, excessive flue gas, combustion vibration, etc. . Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the present invention provides a control method of a gas water heater and a gas water heater. [0004] The invention provides a gas water heater, which includes a ...
