Problems solved by technology

[0002] At present, gas water heaters basically use electric ceramic point auxiliary heating antifreeze equipment. When the outside temperature is low, cold air enters the interior of the gas water heater through the exhaust pipe, which may easily cause the heat exchanger of the gas water heater to freeze and crack due to low temperature. In addition, in the northern region, the outdoor temperature is low in winter. Since the exhaust pipe of the gas water heater is located outdoors, it is easy to block the exhaust pipe due to freezing of condensed water or snowing, resulting in difficulty in exhausting the smoke, which may seriously burn the gas water heater.

Abstract

The invention provides an anti-freezing gas water heater and a control method thereof. The anti-freezing gas water heater comprises a gas water heater body, a smoke discharge pipe, a heating assembly,a temperature sensing part, a wind pressure switch and a controller. The heating assembly is arranged on the inner wall of the smoke discharge pipe. The temperature sensing part is arranged on the smoke discharge pipe and transmits detected temperature information to the controller. The controller is used for controlling the heating assembly. The wind pressure switch used for sensing the magnitude of the wind pressure is arranged at a smoke discharge port of the smoke discharge pipe and transmits wind pressure information to the controller. The controller controls the heating assembly to operate. The temperature sensing part can detect the temperature of the smoke discharge pipe. The controller controls starting of the heating assembly. The heating assembly is used for heating the interior of the smoke discharge pipe to prevent cold air from going from the smoke discharge pipe into the gas water heater and freezing and bursting a heat exchanger in the gas water heater, and follow-up loss is prevented. As the smoke discharge pipe is heated through an electric heating pipe and a draught fan, the anti-freezing gas water heater is more uniform in heating and improves the heating efficiency.
