Description
Technical Field
[0001] The utility model relates to the technical field of compressors, and more specifically, to a compressor supporting structure. Background Art
[0002] The refrigeration compressor is installed on a household or commercial refrigerator or freezer. When working, the refrigerant enters the refrigeration system through the suction pipe, suction silencer, cylinder, exhaust chamber, inner exhaust pipe, and exhaust pipe. In this process, the piston will reciprocate, causing the movement to vibrate, and the vibration is transmitted to the shell along the support structure of the movement and the inner exhaust pipe. The existing movement support structure generally includes a gasket, an upper bushing, a spring, a lower bushing and a convex nail. The movement and the upper bushing are fixedly connected. The vibration of the movement along the support structure is mainly damped by the spring. At the moment when the compressor is started or when the variable frequency compressor is running at a low speed, the vibration amplitude of the compressor is relatively large, which is easy to cause the shell collision phenomenon (collision between the upper shell of the movement and the spring). At the same time, due to the excessive swing amplitude of the compressor, it will also cause friction noise between the spring and the upper bushing and the lower bushing, which will bring a bad user experience.

[0005] The utility model provides a compressor support structure, which, under the protection of the buffer component, can control the shell collision phenomenon that may occur when the compressor is started or running at a low speed to a certain extent, and at the same time can reduce the friction noise between the support spring and the lower bushing caused by the excessive swing amplitude of the compressor.
[0006] Preferably, a sleeve is provided on the outside of the buffer, and the sleeve is a cylindrical structure, which can surround the outside of the buffer; there is a gap between the buffer and the sleeve. Through the cooperation of the sleeve and the buffer, the compressor can be further controlled at the moment of startup or when running at a low speed to avoid the shell collision phenomenon, and at the same time, the friction noise between the support spring and the lower bushing can be further reduced; the buffer can also be further protected.

[0010] Preferably, the buffer member is made of damping material to reduce the friction noise between the support spring and the lower bushing.
[0011] Preferably, a plurality of buffer notches are provided at intervals at the end of the buffer, so that the buffer at the notch can swing more significantly, thereby reducing the vibration effect of the support spring and the lower bushing on the entire buffer when vibrating, so that the buffer can better eliminate vibration noise.
[0012] Preferably, the notch of the buffer is semicircular, so that the buffer is more durable.
[0013] Preferably, the end of the sleeve is provided with a plurality of sleeve notches at intervals, so that the collar at the notch can swing more significantly, so that when the buffer vibrates, the overall vibration of the sleeve is affected, the sleeve amplitude is smaller, and vibration noise is better eliminated.
