Meanwhile, the concave ribs 120 and the convex ribs 130 on the tank wall and/or the bin wall 110 optimize the dynamic stiffness of the tank wall and/or the bin wall 110 (as shown in fig. 11), and change the natural frequency of the tank wall and/or the bin wall 110, so that the natural frequency of the tank wall and/or the bin wall 110 is not overlapped with the resonance frequency of the compressor after being changed, and resonance can be avoided. That is, the concave ribs 120 and the convex ribs 130 can reduce the transmission of vibration from the compressor to the tank wall and/or the tank wall 110, thereby reducing vibration of the entire compressor tank and housing.

In the refrigerating and freezing apparatus of the present utility model, the concave ribs 120 and the convex ribs 130 are provided on the wall and/or the wall 110, so that the natural frequency of the wall and/or the wall 110 is avoided, thereby reducing the low frequency vibration in the prior art. In addition, the concave ribs 120, the convex ribs 130 and the silencing device jointly absorb air sound, so that the noise of a compressor bin can be obviously reduced, the sound quality of the refrigerating and freezing device is improved, and the aim of improving user experience is fulfilled.

When the silencer is used, the silencer can be placed inside and outside the compressor bin of the refrigerator, and when noise in the compressor bin is transmitted from inside to outside, the noise is obviously reduced under the silencing effect of the silencer through the silencer inside and outside the compressor bin.

In this embodiment, by simultaneously providing the muffler inside and outside the compressor compartment, the noise reduction effect can be further improved.

As shown in fig. 4 to 10, in some alternative embodiments of the present utility model, the muffler device includes a muffler body 210, at least one muffler cavity 240 is provided in the muffler body 210, a heat dissipating hole 230 penetrating through the muffler body 210 is provided on the muffler body 210, at least one first sound absorbing hole is provided on a peripheral wall of the heat dissipating hole 230, each first sound absorbing hole is communicated with the at least one muffler cavity 240, and a first through hole corresponding to the heat dissipating hole 230 is provided on the corresponding bin wall 110.

When the muffler device is used, when noise in the compressor bin propagates from inside to outside, through the muffler body 210, the noise can enter the corresponding muffler cavity 240 through the first sound absorption hole when passing through the heat dissipation hole 230, and the noise is obviously reduced under the muffler effect of the muffler cavity 240.

As shown in fig. 5-10, in some alternative embodiments of the present utility model, the muffler device further includes second sound absorbing holes 220, at least one of the second sound absorbing holes 220 being located on a side wall of the muffler body 210, each of the second sound absorbing holes 220 being in communication with at least one of the muffler chambers 240, the second sound absorbing holes 220 opening toward the interior of the compressor compartment. When the silencer is installed on the outer side of the bin wall 110, a second through hole corresponding to the second sound absorption hole 220 is formed in the corresponding bin wall 110.

Specifically, the sidewall of the sound damping body 210 provided with the second sound absorbing hole 220 is the sound inlet surface 211. The second sound absorbing holes 220 and the sound deadening chamber 240 constitute a blind-hole-like structure.

The working process of the silencer in the embodiment is as follows: when in use, the silencing body 210 can be placed inside or outside the compressor bin of the refrigerator, the second sound absorption holes 220 face the inner side of the compressor bin, when noise in the compressor bin propagates from inside to outside, part of the noise passes through the silencing body 210 inside or outside the compressor bin, and enters the silencing cavity 240 through the second sound absorption holes 220 under the blocking effect of the side wall of the silencing body 210; another part of the noise enters the corresponding sound-deadening chamber 240 through the first sound-absorbing hole when passing through the heat-radiating hole 230, and the noise is remarkably reduced under the sound-deadening effect of the sound-deadening chamber 240.

In this embodiment, two sound absorption modes of side sound absorption and inner sound absorption are adopted at the same time. Compared with the arrangement of the second sound absorption holes 220 on the wall of the heat dissipation hole 230, the arrangement of the second sound absorption holes 220 on the side wall of the sound attenuation body 210 can further improve the sound attenuation amount, thereby further improving the use experience of users.

In some alternative embodiments of the present utility model, at least one sound attenuation chamber 240 is in a honeycomb structure.

In some alternative embodiments of the present utility model, the sound-deadening chamber 240 in which the second sound-absorbing hole 220 communicates and the sound-deadening chamber 240 in which the second sound-absorbing hole 220 communicates communicate.

In the present embodiment, since the second sound absorption hole 220 is not communicated with the sound absorption chamber 240 corresponding to the second sound absorption hole 220 and the sound absorption chamber 240 corresponding to the second sound absorption hole 220, that is, the second sound absorption hole 220 is not communicated with the heat dissipation hole 230, the sound absorption effect can be further improved.

In some alternative embodiments of the present utility model, the sound-deadening chamber 240 in which the second sound-absorbing hole 220 communicates and the sound-deadening chamber 240 in which the first sound-absorbing hole communicates do not communicate. The sound-deadening chamber 240 with which the second sound-absorbing hole 220 communicates is near the inside of the sound-deadening body 210, and the sound-deadening chamber 240 with which the first sound-absorbing hole communicates is near the outside of the sound-deadening body 210.
