Describe according to the reservoir 100 of the compressor assembly 300 of the embodiment of the present invention below with reference to Fig. 1-Figure 11, reservoir 100 can be in rotary compressor assembly.In description below the application, describe as example for rotary compressor assembly taking reservoir 100.Certainly, those skilled in the art are appreciated that the compressor assembly that can also be used for other type according to the reservoir 100 of the embodiment of the present invention, and are not limited to rotary compressor assembly.
As shown in Figure 1, according to the reservoir 100 of the compressor assembly 300 of first aspect present invention embodiment, comprise housing 1 and dynamic vibration absorber 2.
Wherein, with reference to Fig. 5 and Figure 10, compressor assembly 300 comprises compressor 200 and reservoir 100, reservoir 100 is located at outside compressor 200, and for example reservoir 100 can be fixed on the outer wall of compressor 200, and now reservoir 100 is fixed with respect to compressor 200, reservoir 100 is communicated with the compression chamber of compressor 200 inside, so that cold-producing medium is passed in compression chamber and to be compressed, dynamic vibration absorber 2 is located in the housing 1 of reservoir 100, to reduce the tangential vibrations of reservoir 100.
Particularly, as shown in Figure 1-Figure 3, dynamic vibration absorber 2 comprises weight block 21, the first spring 22, the second spring 23 and the first guide rail 24, the two ends of the first guide rail 24 can be connected on the inwall of housing 1, preferably, the first guide rail 24 is flatly arranged in housing 1, to have effectiveness in vibration suppression better, or the first guide rail 24 can also be arranged in housing 1 obliquely.Here, it should be noted that, the retainer 25 that the first guide rail 24 can for example hereinafter be mentioned by other parts is connected on the internal perisporium of housing 1, and certainly, the two ends of the first guide rail 24 can also directly be connected on the internal perisporium of housing 1 (scheming not shown).
Weight block 21 is located on the first guide rail 24 movably, that is to say, weight block 21 can move around on the first guide rail 24, the first spring 22 and the second spring 23 are all set on the first guide rail 24 and lay respectively at the both sides of weight block 21, can effectively prevent like this weight block 21 from directly clashing into the inwall of housing 1 or the inwall of retainer 25 and produce larger noise, each in the first spring 22 and the second spring 23 is all arranged to be suitable for flexibly only support weight block 21.
Here, it should be noted that, " each in the first spring 22 and the second spring 23 is all arranged to be suitable for flexibly only support weight block 21 " can be understood as in the time that compressor assembly 300 is not worked, the first spring 22 and the second spring 23 all have a predeformation, that is to say, the first spring 22 and the second spring 23 are in its pre-compressed state, now the first spring 22 and the second spring 23 all have an elastic acting force to restore to the original state to weight block 21, or in the time that compressor assembly 300 is not worked, the first spring 22 and the second spring 23 all do not have predeformation, in other words, the first spring 22 and the second spring 23 are in without precompressed drift state, now the first spring 22 and the second spring 23 all do not have elastic acting force to weight block 21, state can only be kept in touch with weight block 21 in one end of the first spring 22 and the second spring 23.
Thus, in the time that compressor assembly 300 is worked, reservoir 100 can produce vibration, thereby drive the weight block 21 in housing 1 to move back and forth on the first guide rail 24 along the length direction of the first guide rail 24, and under the effect of the first spring 22 and the second spring 23, absorb compressor 200 rotary vibration energy, be the vibration of balance compressor 200, thereby can effectively reduce the vibration of reservoir 100 and escape pipe 3 thereof, reduce vibration noise.
According to the reservoir 100 of for example rotary compressor assembly of the compressor assembly 300 of the embodiment of the present invention, by housing 1 inside at reservoir 100, dynamic vibration absorber 2 is set, in the time that compressor assembly 300 moves, can reduce the tangential vibrations of reservoir 100 self, thereby the escape pipe 3 that has reduced air-conditioning system vibrates, air-conditioning system pipeline stress and noise level are reduced, because dynamic vibration absorber 2 is arranged in reservoir 100 inside, thereby save space, in addition, dynamic vibration absorber 2 simple in structure, easily realize, and cost is low.
