Compressor damping support device and refrigeration equipment

Abstract

This invention provides a compressor vibration damping support device and a refrigeration device, relating to the field of refrigerator noise reduction technology. The compressor vibration damping support device of this invention, applied to refrigeration equipment, places the compressor feet under the base plate, with the feet directly contacting the ground. This allows the weight of the refrigeration equipment to be applied to the compressor feet, and the rigid ground and the weight of the refrigeration equipment together limit compressor vibration, significantly reducing the amplitude of compressor housing vibration. This reduces vibration transmission from the compressor through the feet and the suction and discharge pipes. The feet support the base plate via vibration damping pads, increasing the longitudinal support stiffness of the base plate and preventing resonant radiation noise under compressor vibration excitation. The compressor feet are connected to the base plate via vibration damping pads, reducing vibration transmission from the compressor to the base plate and thus reducing base plate vibration noise. This invention significantly reduces noise generated by compressor vibration transmission in refrigeration equipment, greatly improving the user experience.

Description

Technical Field

[0001] This invention relates to the field of refrigerator noise reduction technology, specifically to a compressor vibration damping support device and refrigeration equipment. Background Technology

[0002] The compressor is the primary source of vibration in a refrigerator. Refrigeration compressors in refrigerators generally employ a single-stage reciprocating piston structure, inevitably resulting in unbalanced forces that cause the compressor housing to vibrate. This vibration is transmitted to the refrigerator primarily through two pathways. One pathway involves the compressor feet transmitting the vibration downwards to the refrigerator base, and then to the refrigerator body, generating vibration-radiated noise. The compressor is mounted on the upper surface of the refrigerator base, which supports the compressor, drip tray, and other components, as well as the entire refrigerator body. The refrigerator base is a thin metal plate, fixed at both ends with a large area suspended in the middle. Its longitudinal stiffness is relatively low, making it prone to resonant radiated noise under compressor vibration. If the base's support stiffness is insufficient or the vibration transmitted from the compressor to the base is excessive, the resonant noise from the refrigerator base will increase, consequently increasing the vibration transmitted from the base to the refrigerator body, and ultimately increasing the resonant radiated noise from the refrigerator body. The other pathway involves the vibration transmitted through the intake and exhaust pipes, generating vibration noise from the pipes and connecting components. The vibration of the compressor casing is transmitted directly outward through the metal suction and exhaust pipes. This vibration, transmitted along the pipes, excites resonant radiated noise. Additionally, the connection between the exhaust pipe and the plastic drip tray causes resonant radiated noise from the drip tray. Furthermore, some refrigerators house condensers, cooling fans, and plastic air deflectors within the compressor compartment, all of which generate resonant radiated noise due to the excitation of exhaust pipe vibration. These two vibration transmission pathways are the primary sources of refrigerator noise, significantly impacting the overall noise level and user comfort. Summary of the Invention
