Abstract
The utility model relates to a refrigerator compressor with an improved shell structure, which comprises a compressor body and a shell. An air inlet and an air exhaust opening are formed on the shell; the shell is double-layered and is divided into an shell outer layer and an shell inner layer; a gap is arranged between the shell outer layer and the shell inner layer; the shell outer layer is connected with the shell inner layer through a connecting strip; and a plurality of through holes are formed on the shell inner layer. In the utility mode, the double-layered shell is arranged, so that the rigidity and the inherent frequency of the shell are increased; and in addition, a sound wave loses part of energy in a cavity formed by the gap after passing through the through holes, so that the noise is reduced greatly.
Description
(1) technical field
The utility model relates to a kind of compressor, particularly relates to a kind of refrigerator compressor.
(2) background technique
Compressor mainly is suction, compression and the conveying that realizes refrigeration agent, in compressor operation, and its noise source more complicated, conclusion is got up, mainly from three major types: mechanical noise, aerodynamic noise and electromagnetic noise.The method that reduces noise at present is generally all comparatively complicated, fix a silencer more, utilize the unexpected expansion of pipeline section or contraction to cause acoustic impedance sudden change in the passage, make along the sound wave of some frequency of the purling ripple of pipeline and can't pass silencing apparatus and the reflected back source of students is gone, or improve the electric machine structure design.As open day be on December 07th, 2005 application number be 200410019404.1 hermetic motor compressor exhaust structure and silencer thereof, this structure includes compressor case, electronic and press part composition, shell between electronic and the press part is provided with outlet pipe, and the exhaust honeycomb duct is set at the exhaust side of cylinder assembly, the exhaust honeycomb duct is communicated with outlet pipe, the cold media air water conservancy diversion of discharging in outlet pipe.A kind of silencer that is used for the hermetic motor compressor exhaust structure also is provided, promptly is provided with the silencer that makes the sound attenuation band resonant cavity when discharging refrigerant, and have the exhaust honeycomb duct of certain-length and internal diameter its outlet setting in the discharge side of compression volume.Howsoever, a compressor finally still produces noise with the closed casing vibration to extraradial form, so design of shell is considerable.Also have some to add a sound insulation shell in compressor outside, as open day be on July 16th, 2003 patent No. be the compressor of 02157844.3 band sound insulation shell, comprising: a shell that contains confined space; A compression device that is embedded in shell upper is carried out squeeze operation; A driving arrangement that is embedded in outer casing underpart, required driving force when producing the compressor compresses operation; And a sound insulation shell that is fixed on the shell upper outer ring surface, prevent the noise unofficial biography that compressor produces.By the enclosure at compressor a sound insulation shell is installed directly, can be reduced noise to a certain extent, but hindered the heat radiation of compressor, regular meeting causes overheat of compressor.
(3) summary of the invention
In order to overcome the deficiency of above-mentioned technical problem, the utility model provides a kind of shell mechanism comparatively rationally can effectively reduce the freezer compressor of noise.
The technical scheme in the invention for solving the technical problem is:
The improved freezer compressor of a kind of shell mechanism, comprise compressor body and shell, shell is provided with suction port and relief opening, described shell is double-deck, be respectively the outer and shell internal layer of shell, be provided with the gap between shell skin and the shell internal layer, shell outer with the shell internal layer between be connected by connection strap, the shell internal layer is provided with some through holes.
Double-deck shell has improved the rigidity and the natural frequency of shell, reduce the vibration of housing, gap between shell internal layer and the shell skin is equivalent to a noise elimination cavity, sound wave is after the through hole of shell internal layer enters into the gap, because the increase in space, and sound wave reflects in this chamber and cancels out each other, and noise reduces greatly.
The hole size of shell internal layer is identical, and distributes in order.Through hole can be distributed in the shell internal layer in order, and size is identical, and the shape of through hole also can have various variations.
As improvement, the outer internal surface of shell is provided with sound-absorbing material.The sound-absorbing material of the outer field internal surface of shell can absorb the sound wave of a part, reduces noise.
The beneficial effects of the utility model are: the utility model is arranged to bilayer with shell, promptly at the outer inner one deck internal layer with holes of setting up again of shell, the rigidity and the natural frequency of shell have been increased, sound wave falls portion of energy through the chamber internal loss of forming in the gap behind the through hole in addition, greatly reduces noise.
(4) description of drawings
Fig. 1 is the sectional structure schematic representation of the utility model shell.
(5) embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
The improved freezer compressor of a kind of shell mechanism, comprise compressor body and shell, shell is provided with suction port 4 and relief opening 5, shell includes two-layer, be respectively shell outer 1 and shell internal layer 2, be provided with the gap between shell outer 1 and the shell internal layer 2, shell is outer to be connected by connection strap with the shell internal layer, and promptly both are connected as a single entity.Shell internal layer 2 is provided with the identical through hole 3 of several sizes, and through hole 3 is orderly arrangement, and the outer field internal surface of shell is provided with sound-absorbing material 6.
Claims (3)
1. improved freezer compressor of shell mechanism, comprise compressor body and shell, shell is provided with suction port and relief opening, it is characterized in that described shell is double-deck, be respectively shell skin (1) and shell internal layer (2), be provided with the gap between shell skin (1) and the shell internal layer (2), shell outer with the shell internal layer between be connected by connection strap, the shell internal layer is provided with some through holes (3).
2. the improved freezer compressor of a kind of shell mechanism according to claim 1 is characterized in that through hole (3) size of described shell internal layer (2) is identical, and distributes in order.
