Abstract

The invention discloses an air conditioner and a noise elimination method of the air conditioner. The air conditioner comprises a compressor, a draught fan, two noise elimination modules arranged for the compressor and the draught fan which serve as noise sources, and a noise processing module. Each noise elimination module comprises a noise detection module, an analog-to-digital conversion module, a digital-to-analog conversion module and a sound generation module. For each noise source, the corresponding noise detection module is used for collecting noise emitted by the noise source, converting the collected sound into an analog electric signal and outputting the analog electric signal, the corresponding analog-to-digital conversion module is used for converting the analog electric signal into a digital signal value, the noise processing module is used for working out a digital output signal value according to the obtained digital signal value and outputting the digital output signal value, the corresponding digital-to-analog conversion module is used for converting the received digital output signal value into an analog electric signal and outputting the analog electric signal, the corresponding sound generation module is used for converting the analog electric signal output by the digital-to-analog conversion module into sound and outputting the sound which is used for counteracting the noise of the noise source, and therefore the purpose that the operation noise of the air conditioner is lowered is achieved.

Description

technical field [0001] The invention relates to the field of electrical appliances, in particular to an air conditioner and a noise elimination method thereof. Background technique [0002] With the development of social economy and the improvement of people's living standards, air conditioners have entered thousands of households and are widely used. [0003] During the operation of the air conditioner, certain noise (also known as noise) will be generated by the operation of the compressor, the rotation of the fan, the flow of refrigerant in the pipeline, and the opening and closing of various valves; among them, the noise generated by the operation of the compressor and the rotation of the fan is relatively large. Therefore, the compressor and fan are the main noise sources during the operation of the air conditioner. The noise may make the user feel uncomfortable, or make the user feel irritable; high-intensity noise in certain frequency bands may even affect the user's...
