Abstract

The invention belongs to the technical field of air conditioners, particularly relates to an air conditioner indoor unit, and aims at solving the problem that the noise reduction effect of an existing air conditioner indoor unit is greatly limited due to the fact that most noise generated by the existing air conditioner indoor unit can still be spread into a room through an air outlet. A noise collector and an anti-noise generator are arranged on an indoor unit body, the signal input end of a computer board in the indoor unit body is in communication connection with the noise collector, and the signal output end of the computer board is in communication connection with the anti-noise generator. In this way, the air conditioner indoor unit can generate anti-noise data according to the noise data received by the noise collector, and the anti-noise generator sends out sound waves which have the same frequency as the noise and have the phase difference of half a period with the noise, so that the noise generated by the indoor unit body is weakened or counteracted. Meanwhile, a sound production opening of the anti-noise generator is located on the same side of the air outlet of the indoor unit body, and the noise reduction effect of the air conditioner indoor unit is guaranteed more reliably.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to an indoor unit of an air conditioner. Background technique [0002] During the operation of the indoor unit of the air conditioner, the rotation of the fan and the swing of the swing blades will generate noise. If the noise is not effectively controlled, especially at night, it will greatly affect people's normal rest. [0003] Existing indoor units of air conditioners generally absorb the noise generated by themselves by using sound-absorbing materials, but a large part of the noise generated by indoor units of air conditioners can still be transmitted to the room through the air outlet, making the existing indoor units of air conditioners less expensive. The noise effect is greatly limited. [0004] Correspondingly, the art needs a kind of new air conditioner indoor unit to solve the above problems. Contents of the invention [0005] In order to solve t...
