Problems solved by technology
When the natural frequency of the damping foot pad is close to the operating frequency of the compressor, most of the vibration excitation of the compressor foot will be transmitted to the bottom plate of the refrigerator through the foot pad, which will cause the bottom plate of the refrigerator to resonate, resulting in fundamental frequency resonance noise, affecting user experience

The invention discloses a foot pad, a compressor and a refrigerator. The foot pad comprises a body, the body is provided with a mounting through hole and a plurality of vibration reduction holes, the plurality of vibration reduction holes are circumferentially distributed at intervals around the mounting through hole, and at least parts of the vibration reduction holes penetrate through the upper end face and the lower end face of the body in the axial direction of the body. At least parts of the vibration reduction holes penetrate through the upper end face and the lower end face of the body, so that a bearing part of the foot pad is of a hollow structure, the whole foot pad can be softened, the axial rigidity and the shearing rigidity of the foot pad are reduced, the inherent frequency of the foot pad can be reduced, the resonance frequency of the compressor and a refrigerator bottom plate is avoided, vibration transmission from the compressor to the refrigerator bottom plate can be reduced, and buzz noise generated by resonance of the compressor and the refrigerator bottom plate is avoided; and in addition, the production cost can be reduced.
Description
technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a foot pad, a compressor and a refrigerator. Background technique [0002] In addition to the important freezing capacity of the refrigerator, its stability and safety are also one of the most critical indicators of the refrigerator. The vibration damping pad of the compressor is an important part connecting the compressor and the refrigerator box, and its vibration damping effect directly affects the vibration and noise level of the entire refrigerator system. When the natural frequency of the damping foot pad is close to the operating frequency of the compressor, most of the vibration excitation of the compressor foot will be transmitted to the bottom plate of the refrigerator through the foot pad, which in turn will cause the bottom plate of the refrigerator to resonate, generating fundamental frequency resonance noise and affecting user experience.
