Publication number: 20240085058Abstract: Provided is a gas water heater. The gas water heater includes a pre-mixer, a combustor having a combustion chamber in communication with a premixing chamber, a condensate water assembly configured to receive and discharge condensate water, and an apparatus for controlling the gas water heater. The pre-mixer includes a premixing chamber and an air intake fan that is configured to supply air to the combustion chamber. The air intake fan is disposed in the premixing chamber. The method includes: acquiring an intake air pressure threshold; acquiring an air intake pressure value of the air intake fan; and controlling, in response to determining based on the air intake pressure value and the intake air pressure threshold that a water seal of the condensate water assembly is at risk of being blown away, the gas water heater to stop operation.Type: ApplicationFiled: February 18, 2022Publication date: March 14, 2024Inventors: Yanjing ZHANG, Huan SUN, Jiqing MA, Guorong LIANG, Zuan LU
