Air pressure detection device, combustor, gas water heater, method and apparatus for controlling gas water heater, and computer-readable storage medium

A gas water heater, wherein the gas water heater is provided with a cold-water inlet pipe and a hot-water outlet pipe, the gas water heater comprising:

• a pre-mixer comprising a premixing chamber and an air intake fan disposed in the premixing chamber;
• a combustor having a combustion chamber and in communication with the premixing chamber;
• a condensate water assembly in communication with the combustion chamber;
• and
• an apparatus for controlling the gas water heater,
• wherein the apparatus is configured to control, in response to determining based on an acquired air intake pressure value and an intake air pressure threshold that a water seal of the condensate water assembly has a fault, the gas water heater to stop operation;
• wherein the intake air pressure threshold comprises a water seal blown-away air pressure alert value and a water seal blown-away air pressure critical value smaller than the water seal blown-away air pressure alert value.

A non-transitory computer-readable storage medium, having a gas water heater control program stored thereon, wherein the gas water heater control program, when executed by a processor, causes the processor to:

• acquire an air intake pressure value of an air intake fan;
• acquire a water seal protection pressure threshold of a condensate water assembly;
• and
• control, in response to determining based on the air intake pressure value and an intake air pressure threshold that a water seal of the condensate water assembly has a fault, the gas water heater to stop operation;
• wherein the intake air pressure threshold comprises a water seal blown-away air pressure alert value and a water seal blown-away air pressure critical value smaller than the water seal blown-away air pressure alert value.
