A limiting plate 6 is slidably arranged inside the mounting groove 5, and a connecting plate 7 is fixedly arranged at the bottom of the limiting plate 6. A sound-absorbing plate 8 is fixedly arranged at the bottom of the connecting plate 7. The longitudinal cross-section of the mounting groove 5 and the longitudinal cross-section of the limiting plate 6 are both T-shaped. The mounting groove 5 and the limiting plate 6 are adapted to each other. The setting of the mounting groove 5 and the limiting plate 6 with a T-shaped longitudinal cross-section, when the limiting plate 6 is installed inside the mounting groove 5, will not fall out of the mounting groove 5, so that the connecting plate 7 and the sound-absorbing plate 8 can be installed. A sound-absorbing hole 9 is penetrated on the surface of the sound-absorbing plate 8. The number of the sound-absorbing plates 8 is several, and the several sound-absorbing plates 8 are symmetrically distributed, and the sound-absorbing plates 8 are inclined. The noise can be eliminated multiple times by using several sound-absorbing panels 8, thereby reducing the noise. The sound-absorbing holes 9 can be set to increase the air flow rate. A connecting hinge 10 is fixedly set on the right side of the sound-absorbing box 1. A box door 11 is hingedly set on the surface of the sound-absorbing box 1 through the connecting hinge 10. A sound-absorbing layer 3 12 is overlapped inside the box door 11. The thickness of the sound-absorbing layer 1 2, the sound-absorbing layer 2 3 and the sound-absorbing layer 3 12 are the same. The sound-absorbing layer 1 2, the sound-absorbing layer 2 3 and the sound-absorbing layer 3 12 are all made of sound insulation cotton. The sound-absorbing layer 1 2, the sound-absorbing layer 2 3 and the sound-absorbing layer 3 12 can be easily eliminated by cooperating with the sound-absorbing panels 8. A recess for installing the sound-absorbing layer 3 12 is provided on one side of the box door 11 close to the sound-absorbing box 1. The groove is recessed toward the front side in the horizontal direction. The arrangement of the groove facilitates the installation of the third sound-absorbing layer 12, thereby facilitating the elimination of noise. A fixing assembly is arranged on the left side of the door 11. The arrangement of the sound-absorbing box 1, the sound-absorbing layer 1 2, the sound-absorbing layer 2 3, the mounting plates 4, 5 mounting grooves, the limit plates 6, 7 connecting plates, the sound-absorbing plates 8, the sound-absorbing holes 9, the connecting hinges 10, the door 11 and the sound-absorbing layer 3 12 facilitates the silencing of the connecting pipe of the refrigerator compressor and facilitates the replacement of the internal structure of the connecting pipe silencer of the refrigerator compressor, thereby avoiding the situation in which the connecting pipe silencer of the refrigerator compressor that is welded cannot be replaced after being damaged, and making the connecting pipe silencer of the refrigerator compressor more convenient to use.

[0023] Specifically, the fixing assembly includes a fixing plate 13, a locking plate 14 is overlapped on the rear side of the fixing plate 13, a fixing bolt 15 is arranged inside the fixing plate 13, and the fixing plate 13 is fixed to the locking plate 14 by the fixing bolt 15. Through the arrangement of the fixing plate 13, the locking plate 14 and the fixing bolt 15, it is convenient to lock the position of the box door 11, thereby avoiding the box door 11 from being accidentally opened after being closed.

[0024] During use: the air outlet pipe 16 is installed at the air inlet end of the refrigerator compressor, and the air enters the sound-absorbing box 1 through the air inlet pipe 17, and the noise generated during the gas flow is absorbed by the sound-absorbing layer 1 2, the sound-absorbing layer 2 3 and the sound-absorbing layer 3 12. When the air enters and exits the sound-absorbing plate 8, a part of the noise is reflected by the sound-absorbing plate 8, and it rubs with the air through the sound-absorbing hole 9, thereby reducing the noise again. When the structure inside the sound-absorbing box 1 is damaged, the fixing bolts 15 are removed, the box door 11 is pulled to open through the connecting hinge 10, and the sound-absorbing plate 8 is pulled to drive the connecting plate 7 to move, so that the connecting plate 7 drives the limiting plate 6 to slide out of the mounting groove 5, and the sound-absorbing plate 8 can be replaced. The sound-absorbing layer 1 2, the sound-absorbing layer 2 3 and the sound-absorbing layer 3 12 made of sound insulation cotton have a certain softness, and the damaged sound-absorbing layer 1 2, the sound-absorbing layer 2 3 and the sound-absorbing layer 3 12 can be taken out from the inside of the sound-absorbing box 1 for replacement.
