Abstract

The invention provides a refrigerator, which comprises a cavity, a phononic crystal piece and a compressor, wherein the outside wall surface of the cavity is provided with an installation cavity, the phononic crystal piece is arranged at the inner wall surface of the installation cavity, and the compressor is arranged at the inner bottom wall surface of the installation cavity by foot pads. The refrigerator has the advantages that the noise in the cavity is attenuated by the phononic crystal piece which is arranged in the cavity, the propagation of a large amount of noise to the outside is avoided, and the purpose of denoising the refrigerator is realized; the purchase requirement of a consumer on the refrigerator is well met, and the design concept of product optimizing of an enterprise is realized.

Description

technical field [0001] The invention relates to the field of household appliances, and more specifically, to a refrigerator. Background technique [0002] The noise in the compressor room is one of the main noise sources of the refrigerator, and the noise has complex components and a wide frequency range, including low-frequency noise, intermediate-frequency noise and high-frequency noise. The root cause of this noise is the mechanical operation sound of the compressor, the electromagnetic noise of the compressor, the resonance sound of the air column of the compressor, the pressure pulsation sound formed by the periodic opening and closing of the suction and discharge valves of the compressor, and the sound of the installation cavity. Noise generated by vibration and collision of indoor pipelines. In addition, the installation chamber of some models of refrigerators is also equipped with a cooling fan, which will also generate noise. [0003] At present, the compressors a...
