At present, the mounting assembly of the compressor mainly comprises: compressor stabilizer blade, compressor bottom plate, bolt and nut, steel bushing and damping callus on the sole, see fig. 5, all set up porosely on compressor stabilizer blade 21 and compressor bottom plate 4, steel bushing 18 embolias in the through-hole of damping callus on the sole 7, and damping callus on the sole 7 inserts the downthehole of compressor stabilizer blade, and ordinary bolt 19 passes steel bushing 18 and stretches out from the through-hole of damping callus on the sole, installs the compressor on the compressor bottom plate with the cooperation of nut 8.

The compressor can generate vibration in the vertical, horizontal and front-back directions during operation, and the vibration is transmitted to the bottom plate of the compressor through the fastening bolts, the steel sleeves and the vibration reduction foot pads, and then is transmitted to the steel plate on the side face of the refrigerator body, the door body and the interior of the refrigerator. Research finds that the existing compressor mounting mode can effectively reduce vibration transmission in the vertical direction through the vibration reduction foot pad, but has poor vibration reduction effect on vibration in the horizontal direction and the front-back direction. For the front and back and left and right directions, the vibration of the compressor is transmitted to the steel sleeve through the bolt to cause the vibration of the steel sleeve, and the steel sleeve does not have the vibration reduction function, so that the medium and low frequency noise is easily caused, and the noise decibel value is larger, so that the auditory sense discomfort of a user is caused.
