Active noise reduction device and active noise reduction system of air conditioner

Abstract

The invention discloses an active noise reduction device of an air conditioner. The active noise reduction device comprises an air conditioner main body, and the bottom of the left side of the air conditioner main body communicates with an air inlet pipe. The air inlet pipe, a sound absorption cotton sleeve, an inflation ring, an inflation pipe, a supporting rod, a connecting inclined rod and an air breaking arc plate are used, noise reduction of the air inlet pipe is achieved through vortex changes of the air direction and the sound absorption cotton sleeve, a power source body is used for providing power support for the device, a noise reduction groove box, a telescopic column, an inserting plate, a telescopic rod, a bottom plate, blocks, a telescopic plate, a telescopic clamping rod, a sponge body and a fan blade body are used for reducing noise generated by friction between fan blades and air, the exhaust effect of the air conditioner body is enhanced through a fan, an air outlet pipe, a fixing block, an air direction bent pipe, a bent air pipe head, a telescopic hose and a conveying front belt, a top groove body, a motor box, a fan body, a rotating motor and a conveying rear belt are used for enhancing the air inlet effect of the air conditioner body, and a filter screen door is used for filtering dust impurities in air.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an active noise reduction device and an active noise reduction system for an air conditioner. Background technique [0002] With the progress of society and the improvement of people's living standards, the noise from the air conditioner has become one of the main noise sources in the indoor environment, which affects people's daily life. Friction often produces strong noise. At the same time, the wind force in the air inlet pipe and the vibration of the air inlet pipe are also one of the main sources of noise in the air conditioner. In order to reduce the noise of the indoor unit of the air conditioner, the current conventional practice is to reduce the The working power of the indoor unit reduces the operating speed of the indoor unit to reduce the noise caused by the indoor unit, but this will reduce the cooling and heating efficiency of the air conditioner and reduce...
