Abstract

The invention discloses a gas water heater wind-pressure-resistance control system. The gas water heater wind-pressure-resistance control system comprises a main controller, a direct current speed governing fan, a fan control circuit, a rotating speed feedback circuit and a current feedback circuit; the control end of the main controller is connected with the input end of the fan control circuit, and the output end of the fan control circuit is connected with the control end of the direct current speed governing fan; the input end of the main controller is connected with the output end of the rotating speed feedback circuit and the output end of the current feedback circuit; and the input end of the rotating speed feedback circuit and the input end of the current feedback circuit are connected with the output end of the direct current speed governing fan. Through the gas water heater wind-pressure-resistance control system, backflow of a lot of waste gas and flame overflowing are effectively avoided, noise and electric leakage hidden danger are well controlled, accordingly, the product adaptation and comfort of a gas water heater are further improved, and the effect that combustion noise, fumes and heat efficiency reach the best state is ensured.

Description

technical field [0001] The invention relates to the technical field of fluid heater control, in particular to a gas water heater anti-wind pressure control system. Background technique [0002] As gas water heaters enter thousands of households, the problem of gas water heaters using AC single-phase asynchronous fans for exhaust air has become prominent, resulting in products that are prone to flue blockage protection in special environments, such as special environments including Northwest China and Northwest China where there is a large temperature difference between indoor and outdoor. The cold and windy eastern coastal areas and some users installed in high-rise air outlets not only produce a large amount of exhaust gas backflow, but also cause flame overflow, and the noise and leakage hidden dangers generated by gas water heaters are not easy to control, and even cause the safety of users' lives and property. ; At the same time, the product adaptability and comfort of t...
