Automatic dust removal control circuit of air conditioner

Abstract

The invention provides an automatic dust removal control circuit of an air conditioner. The control circuit comprises a resistor R1 (1), an NPN type triode Q1 (2), a relay RL1 (3), a light-emitting diode LED1 (4), an N-channel MOSFET Q2 (5), a motor M1 (6), a resistor R2 (7), a resistor R3 (8), an electrolytic capacitor C1 (9), a PNP type triode Q3 (10), and a light sensing sensor VT1 (11). According to the circuit, when external air enters the air conditioner, the detection is carried out, under the condition of more dust, the light sensing sensor VT1 (11) is cut-off, the NPN type triode Q1 (2) is switched on, the relay RL1 (3) is power-on and pick-up, a dust shielding plate closes, and an electromagnetic valve is pick-up; the dust shielding plate is closed to isolate the external dust from entering; when the amount of dust is reduced to a certain degree, the light sensing sensor VT1 (11) is switched-on, the motor M1 (6) rotates in 2 seconds or within to drive a dust suction fan to rotate, the air in the air conditioner is further sucked away, so that the indoor ventilation is guaranteed, and the amount of dust flowing into a room through the air conditioner is reduced.

Description

technical field [0001] The invention relates to an air conditioner automatic dust removal control circuit. Background technique [0002] At present, with the advancement of urbanization, there are more and more dust and dust in the urban air, and many people suffer from allergic diseases such as rhinitis (especially children). At the same time, one of the hazards of air conditioners is poor air circulation. It is easy to get air-conditioning diseases. At present, the mainstream air-conditioning products on the market also consider the problem of filtering dust and dust, and also install dust-proof nets, but they are fixed and need to be cleaned and replaced regularly, otherwise the air will be blocked or blocked. Road, even more serious pollution of indoor air. Most air-conditioning users do not have the habit of cleaning the dust-proof net in January and changing it every six months, so it is easy to get respiratory diseases in the long run. If the material fee is replace...

[0002] At present, with the advancement of urbanization, there are more and more dust and dust in the urban air, and many people suffer from allergic diseases such as rhinitis (especially children). At the same time, one of the hazards of air conditioners is poor air circulation. It is easy to get air-conditioning diseases. At present, the mainstream air-conditioning products on the market also consider the problem of filtering dust and dust, and also install dust-proof nets, but they are fixed and need to be cleaned and replaced regularly, otherwise the air will be blocked or blocked. Road, and even more seriously polluted indoor air

Most air-conditioning users do not have the habit of cleaning the dust-proof net in January and changing it every six months, so it is easy to get respiratory diseases in the long run

If the material fee is replaced regularly, the door-to-door service fee, etc. will be expensive
