According to the housing 100 for compressor of the utility model embodiment, by being provided with sound absorption structure 30 on the internal surface 10 of housing 100, and the cross section of sound absorption structure 30 is taper or trapezoidal, sound absorption structure 30 can be made to have the character of transition gradually, the acoustic impedance of housing 100 can be mated preferably with the acoustic impedance of air, thus sound wave can be made to enter in sound absorption structure 30, and absorbed efficiently by sound absorption structure 30, and then housing 100 can play the effect of effective noise reduction.
In examples more of the present utility model, sound absorption structure 30 can be bar shaped, and sound absorption structure 30 juxtaposition of multiple bar shaped is to form sound absorption region 40, and multiple sound absorption region 40 is in the distribution of many row's multiple rows.The sound absorption structure 30 in two adjacent sound absorption regions 40 can be 0-180 ° of angle.Alternatively, the angle between the sound absorption structure 30 in two adjacent sound absorption regions 40 can be 90 °.As shown in Figure 2, mark has the sound absorption region 40 of A1 and mark to have the sound absorption region 40 of A2 to be two adjacent sound absorption regions 40, and mark has the sound absorption structure 30 in the sound absorption region 40 of A1 and mark to have the angle between the sound absorption structure 30 in the sound absorption region 40 of A2 to be 90 °.By multiple sound absorption regions 40 multirow, multiple row are arranged, can so that sound absorption structure 30 absorbs sound wave efficiently.
Alternatively, the sound absorption structure 30 in each sound absorption region 40 can parallel to each other and interval.As shown in Figure 2, each sound absorption region 40 comprises three sound absorption structures, 30, three sound absorption structures 30 and is parallel to each other, and three spaced apart settings of sound absorption structure 30.The length of the sound absorption structure 30 in each sound absorption region 40 can be equal, thus each sound absorption region 40 structure can be made neat, is convenient to manufacture, but also can so that sound absorption structure 30 is arranged on the internal surface 10 of housing 100.
Alternatively, when the cross section of sound absorption structure 30 is trapezoidal, trapezoidal going to the bottom is fixed on internal surface 10, and trapezoidal upper base is configured to free end.Be understandable that, the width of the end face of the sound absorption structure 30 of bar shaped is less than the width of bottom surface, and sound wave can enter in sound absorption structure 30 from the end face of sound absorption structure 30, and the sound absorption structure 30 with transition nature gradually can absorb sound wave efficiently.
When the cross section of sound absorption structure 30 is taper, the bottom surface of taper is fixed on internal surface 10, and the pointed tip configuration of taper is free end.Be understandable that, sound wave can enter in sound absorption structure 30 from the top of sound absorption structure 30, and the sound absorption structure 30 with transition nature gradually can absorb sound wave efficiently.
Alternatively, sound absorption structure 30 can by being formed housing 100 punching press.The sound absorption structure 30 that punching press is formed can be arranged on the internal surface 10 of housing 100 preferably, makes housing 100 structural stability.
For the ease of forming sound absorption structure 30 by stamping process, sound absorption structure 30 can be arranged on the relatively little part place of the radian of housing, such as, be arranged on the part that housing is relatively straight or mild, can reduce punching press difficulty like this, reduces cost.
According to the reciprocal compressor of the utility model embodiment, comprise the housing 100 for compressor of above-described embodiment.The reciprocal compressor noise with the housing 100 of above-described embodiment is little.
In the description of this specification, specific features, structure, material or feature that the description of reference term " embodiment ", " some embodiments ", " example ", " concrete example " or " some examples " etc. means to describe in conjunction with this embodiment or example are contained at least one embodiment of the present utility model or example.In this manual, to the schematic representation of above-mentioned term not must for be identical embodiment or example.And the specific features of description, structure, material or feature can combine in an appropriate manner in any one or more embodiment or example.In addition, the different embodiment described in this specification or example can carry out engaging and combining by those skilled in the art.
Although illustrate and described embodiment of the present utility model above, be understandable that, above-described embodiment is exemplary, can not be interpreted as restriction of the present utility model, those of ordinary skill in the art can change above-described embodiment, revises, replace and modification in scope of the present utility model.
