The embodiment of the present invention one provides a kind of silencing means, as described in Figure 1, comprising:
Shell 1, the shell 1 is by bottom surface 12 and the side 11 upwardly extended around the bottom surface 12, the bottom surface 12
Internal cavities are collectively formed with side 11, the top surface opposite with the bottom surface 12 is the opening being connected with the internal cavities；
Here, which can be various shape, for example, round, square or rectangular etc..
L-shaped first partition 4 is provided in the internal cavities, first partition 4 is by horizontally disposed 41 He of transverse slat
Vertically disposed riser 42 forms, and there are gap between the transverse slat 41 and bottom surface, the riser 42 extends upwardly to described open
Mouthful；Here, the riser 42 of first partition 4 is upwardly extended up to the opening, then it is understood that opening can be divided by riser 42
It is segmented into two parts.Here it is possible to understand, transverse slat 41 and riser 42 are all a sheet, transverse slat 41 and the common structure of riser 42
It is at L-shaped.
Transverse slat 41 extends in locating horizontal plane until be connected with the side 11, and riser 42 vertical is put down locating
Extend in face until being connected with the side 11, and the internal cavities are divided into mutual disconnected two cavitys.Here,
Since first partition 4 is in internal cavities, transverse slat 41 extends in the horizontal plane locating for it, then final 41 meeting of transverse slat
It is in contact with side 11.Here, since riser 42 extends upwardly to the opening, then riser extends in locating perpendicular
When, opening is not exceeded upwards, and when extending to two sides, then final riser 42 can be in contact with side 11.
Here, as shown in Figure 1, transverse slat 41 and riser 42 constitute an entirety, it is divided into two not connect mutually internal cavities
Logical cavity, and the two cavitys all have independent sub- opening；It here, will include the sky between transverse slat 41 and bottom surface 12
The cavity of gap is known as the first cavity 21, and the opening of the cavity is known as the first son opening；Another cavity is known as the second cavity 22, should
The opening of cavity 22 is known as the second son opening.It is understood that the sum of 22 volume of the first cavity 21 and the second cavity is equal to interior
The volume of portion's cavity, and the position of transverse slat 41 or the position of horizontal adjustment riser 42 are adjusted up and down, thus it is possible to vary first is empty
The volume of chamber 21 and the second cavity 22.
Here it is possible to understand, the first, second cavity is resonant cavity muffler, and resonant frequency are as follows:Wherein c is the velocity of sound, and V is resonant cavity volume (i.e. the volume of the first, second cavity), and G is conductivity, is one
Physical quantity as unit of length.It is understood that by adjusting the volume of the first, second cavity, it will be able to adjust first,
The resonant frequency of second cavity, and the first, second cavity is mutually located next to, therefore, not wasting space, so as to effective
Reduce the volume of resonant cavity muffler.For example, multiple resonant cavity mufflers can be set in the press storehouse of refrigerator, pass through tune
The volume of whole first, second cavity, so that the resonant frequency of multiple resonance silencers is equal on the noise band of compressor
Even distribution, to just effectively eliminate the noise of compressor.
Here, since bottom surface 12 can be various shape, for example, circle, square or rectangular etc., thus first, the

Preferably, as shown in figure 4, being setting in the second cavity 21 of bottom surface in the of vertical direction with the transverse slat 41
Second cavity is divided into two mutual disconnected cavitys by two partitions 2, second partition 2.It is understood that the volume of cavity is
It determines a very important parameter of the resonant frequency of resonant cavity muffler, therefore, in practice, the can be used
Second cavity is separated a mutually disconnected cavity two-by-two by two partitions 2 herein, so as to finer control noise reduction dress
The noise reduction frequency set.Optionally, second partition 2 is parallel to first side or second side.
Optionally, the quantity of second partition 2 can be multiple, for example, in the second cavity 21 with the transverse slat 41 for bottom surface
Middle setting is in N number of second partition of vertical direction, and the second cavity is divided into N+1 mutually disconnected cavitys by N number of second partition.
Here, N number of natural number.
Optionally, as described in Figure 5, in the third partition 3 of vertical direction, third partition 3 will for setting in the first cavity 21
First cavity 21 is divided into two mutual disconnected cavitys.It is understood that the volume of cavity is to determine resonant cavity muffler
Resonant frequency a very important parameter, therefore, in practice, can be used third partition 3 by first sky
Chamber separate herein two-by-two a mutually disconnected cavity so as to the noise reduction frequency of the finer control silencing means.It is optional
, third partition 3 is parallel to first side or second side.
Optionally, the quantity of third partition can be multiple, for example, setting is a in the M of vertical direction in the first cavity
First cavity 21 is divided into M+1 mutually disconnected cavitys by third partition, third partition.Here, M natural number.
Optionally, as shown in fig. 6, in practice, third partition 3 can be arranged in the first cavity respectively, in the second sky
Second partition 2 is set in chamber.Here, second partition 2 and third partition 3 can be in the same plane, and can also be located at difference
Plane in.
Preferably, described be open is provided with the sound absorption for covering opening silk floss.Here, one layer of sound absorption is covered in opening
The case where silk floss can make noise reduction band broaden, and avoiding the peak value of main peak noise two sides can not cut down.
Second embodiment of the present invention provides a kind of refrigerators, comprising: the press storehouse of compressor is provided with, in the press storehouse
