Air conditioner and control method for active noise reduction of air conditioner

Abstract

The invention discloses an air conditioner and a control method for active noise reduction of the air conditioner, the air conditioner comprises an air outlet duct, a noise reduction device, a human body detection device and a controller, and the air outlet duct is provided with an air outlet; the noise reduction device is arranged at the air outlet and used for detecting a first noise signal generated in the air outlet duct and outputting a second noise signal opposite to the first noise signal in phase. The human body detection device is used for detecting human body position information; the controller is connected with the human body detection device and the noise reduction device, and the controller is configured to obtain a first noise signal and human body position information, generate a driving control signal of a second noise signal according to the first noise signal, and obtain angle information required by the noise reduction device to output the second noise signal according to the human body position information; and controlling the noise reduction device according to the required angle information and the driving control signal so as to send a second noise signal to the position of the human body. Targeted region noise reduction can be performed according to the human body position, and full-region noise reduction is realized.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner and a control method for active noise reduction of the air conditioner. Background technique [0002] The diversified development of air-conditioning products has made the performance of air-conditioning products the main goal of competition among manufacturers, and effectively solving the noise problem of air-conditioners has become the main battlefield for performance competition among companies. Among them, there are many types of air conditioner noise, and it is troublesome to solve the occasional noise problem. For example, thermal expansion and cold contraction are caused by the deformation of plastic parts, so it is difficult to control the occurrence of occasional noise, and the air conditioner noise problem is easily affected. Consumers complained that active noise reduction technology is often used to solve the noise problem of air conditione...

AI Technical Summary

Problems solved by technology

Among them, there are many types of air conditioner noise, and it is troublesome to solve the occasional noise problem. For example, thermal expansion and cold contraction are caused by the deformation of plastic parts, so it is difficult to control the occurrence of occasional noise, and the air conditioner noise problem is easily affected. Consumers complained that active noise reduction technology is often used to solve the noise problem of air conditioners in the market to achieve the purpose of noise reduction

[0003] In the existing technology, when the active noise reduction technology is used for noise reduction, the noise reduction is only carried out for certain specific areas, which cannot reduce all the noise in the whole house, and may also cause noise superposition in some areas, making the noise in this area Noise enhancement affects user experience
