Abstract

The invention discloses a filter net blockage detection method of an air supply device and the air supply device using the same. The air supply device comprises an air inlet, an air outlet, an air channel, a fan or an air wheel, a fan motor and an air filter net, wherein the air filter net is arranged on the air channel; and the fan motor drives the fan or the air wheel to rotate, so that air enters the air channel from the air inlet and passes through the air filter net and is output from the air outlet. The air supply device is characterized in that the fan motor is used as an air amount detection element; when the detected air amount is lower than a set air amount, whether the air filter net is blocked is judged and a signal is output for warning; no hardware needs to be added; and the installation is convenient and the cost is low.

Description

Technical field: [0001] The invention relates to a method for detecting blockage of a filter screen of air supply equipment and the air supply equipment applied thereto. Background technique: [0002] In recent years, with the increasingly fierce competition in the field of electrical appliances, the technical requirements for products have been continuously improved, such as energy saving and environmental protection, high controllability, intelligent controllability, short development cycle, and low noise. As the core component—the motor, it will undoubtedly become the key component to solve the above technical problems. The motors in traditional household air conditioners generally use single-phase AC motors PSC, single-phase AC motors, low efficiency, relatively energy consumption, large noise, and controllable Sexual intelligence is low. With the development of motor technology, DC motors are gradually replacing AC motors. DC motors have motor controllers, which use mo...
