Air filtering device of automobile air conditioner and using method thereof

Abstract

The invention relates to an air filtering device of an automobile air conditioner. The device comprises an inlet pipeline, an air filter mounting shell, an air filter, a volute shell and an air blower, wherein the air filter mounting shell is arranged in the inlet pipeline, the air filter is arranged on the air filter mounting shell, and the air blower is arranged on the volute shell; the inlet pipeline is provided with an external air inlet and a passenger cabin air inlet, an air inlet switching door is arranged in the inlet pipeline and located between the external air inlet and the passenger cabin air inlet, the inlet pipeline is provided with a second passenger cabin air inlet, and the second passenger cabin air inlet is located below the passenger cabin air inlet; the second cabin airinlet is provided with a hoist, which can selectively open or close the second cabin air inlet. Compared with the prior art, the device is advantaged in that heating efficiency of the automobile airconditioner is improved through preheating, the automobile air conditioner is simple in structure, production cost is reduced, and the automobile assembling time is shortened.

[0002] In general, an air conditioner of an automobile heats or cools cabin air in the cabin of the vehicle or outside air from the atmosphere, and supplies the heated or cooled air into the cabin of the vehicle, thereby controlling the temperature inside the cabin, When the air is supplied to the cabin of the car, it is filtered by the air filter device of the car air conditioner, which absorbs the dust and impurities in the air and prevents the dust and impurities from entering the cabin. Housing, air filter, blower mounting housing and blower, this car air conditioning air filter unit during use, when cold outside air is supplied to the air conditioning unit in heating mode, more energy is required to heat the cabin to The set temperature reduces the heating efficiency of the car air conditioner, and some car air conditioner air filter devices on the market that increase the heating efficiency by improving the structure of the blower or setting the structure of the auxiliary door often require more components, which makes the structure complex and improves It increases the production cost and increases the vehicle assembly time. At the same time, it is easy to generate vibration noise and the airtight effect is poor. The auxiliary door is easy to fail and has a short service life. Air pollution in the passenger compartment of the car is caused. The high-frequency vibration generated by the blower during high-speed operation is transmitted to the blower installation shell, which is prone to generate large noise and cause multiple damages, reducing the service life of the air filter device of the car air conditioner. It is necessary to improve
