Abstract

The invention discloses an electric heater with a fan, a control method and circuit thereof and a domestic appliance. The control circuit of the electric heater with the fan comprises a power supply loop and a control loop, wherein the power supply loop comprises a power supply and an electrical heating module, and the control loop is used for detecting the air duct pressure of the fan of the electric heater and controlling the power supply loop to be disconnected when the air duct pressure is smaller than a preset value. By means of the electric heater with the fan, the control method and circuit thereof and the domestic appliance, the problem that the temperature of an electric heater with the fan can be easily too high in the prior art is solved, so that the service life of the electric heater is prolonged, and the safety effect in operation can be achieved.

Description

technical field [0001] The invention relates to the field of electronic circuits, in particular to an electric heater with a fan, a control method, a circuit and a household appliance. Background technique [0002] At present, household appliances such as air conditioners, humidifiers, and electric heaters generally use electric heaters with fans for heating. When the air volume is reduced, the electric heater cannot be disconnected in time, but will continue to dry, causing the temperature of the electric heater and its surrounding environment to rise sharply, easily burning the electric heater, and causing deformation and malfunction of the household appliances to which the electric heater belongs. failure, at present, the protection of the electric heater mainly depends on the temperature controller on the working circuit of the electric heater (such as the temperature limiter ST, the fuse FUT), specifically, such as figure 1 The control circuit diagram of the electric h...
