Problems solved by technology

[0003] When the gas heating water heater works in the staged combustion mode, if the fixed frequency speed of the fan remains unchanged, it is easy to cause the flame to be drawn away due to the small combustion flame and the fast exhaust speed, and further cause excessive carbon monoxide caused by insufficient combustion. The problem

Abstract

The invention discloses a control method and device of a gas heating water heater. The control method includes the following steps that the combustion state of the gas heating water heater is obtained; the operation state of a fan is adjusted according to the combustion state of the gas heating water heater; and the operation state of the fan corresponds to the combustion state of the gas heatingwater heater. By adjusting the speed of the fan according to the combustion state of the gas heating water heater, it is realized that the fan speed corresponds to the staged combustion state of the gas heating water heater, the situation that flame is pumped away due to the high fan speed is avoided, the defect of excessive carbon monoxide caused by insufficient combustion is overcome, the safetyfactor of the gas heating water heater is improved.

Description

technical field [0001] The invention relates to the technical field of household heating equipment, in particular to a control method and device for a gas heating water heater and a gas heating water heater. Background technique [0002] Gas heating water heaters, also known as gas wall-hung boilers, are water heaters that rely on natural gas to provide hot water. Domestic gas heating water heaters are dual-function household appliances that provide household heating and domestic hot water at the same time. The gas heating water heater has a powerful central heating function in the home. While meeting the heating needs of the home, it can also provide users with domestic hot water, which brings great convenience to users. [0003] When the gas heating water heater works in the staged combustion mode, if the fixed frequency speed of the fan remains unchanged, it is easy to cause the flame to be drawn away due to the small combustion flame and the fast exhaust speed, and furt...
