Abstract
The invention discloses double-deck directly air suction silencer for a kind of refrigeration compressor, for compressor field, comprise the upper cover that is provided with the main body of silencing cavity and fastens with main body, on cover and be provided with the conduit stretching in silencing cavity, in main body, below conduit, be provided with air admission hole, main body comprises internal layer and skin, and internal layer and skin are spaced from each other and form gas interlayer. This refrigeration compressor adopts double-decker by double-deck directly air suction silencer main body, the structure of internal layer, skin and gas interlayer is arranged so that muffler is under less volume, better erasure effect can be provided, save material simultaneously, reduce costs, in addition, also improve the effect of heat insulation of muffler, thereby improved gettering efficiency.
Description
Technical field
The present invention, for compressor field, particularly relates to the direct air suction silencer of a kind of refrigeration compressor.
Background technology
Air suction silencer is applied in hermetically sealed compressor, the general good plastic material of heat-insulating property that adopts is made, being in order to reduce noise on the one hand, is in order to reduce the heat effect of compressor heat to cold-producing medium on the other hand, improves the gettering efficiency of compressor.
The main body of existing air suction silencer all adopts single layer structure design, there is following problem in this structural design: (1) muffler soundproof effect is general, need to strengthen erasure effect, must increase muffler volume or increase muffler wall thickness, this will cause the integrally-built change of compressor, the waste of material and the increase of cost; (2) muffler is single layer structure, and insulation effect is poor, and because motor compressor is in operation process, the movement heat of motor easily heats muffler, and compressor air suction temperature is raise, and gettering efficiency reduces.
Summary of the invention
For addressing the above problem, the invention provides that a kind of volume is little, cost is low, noise reduction thermal insulation is effective and improve the direct air suction silencer of refrigeration compressor of gettering efficiency.
The technical solution adopted for the present invention to solve the technical problems is: double-deck directly air suction silencer for refrigeration compressor, comprise the upper cover that is provided with the main body of silencing cavity and fastens with main body, on cover and be provided with the conduit stretching in silencing cavity, in main body, below conduit, be provided with air admission hole, main body comprises internal layer and skin, and internal layer and skin are spaced from each other and form gas interlayer.
Be further used as the improvement of technical solution of the present invention, the porch, lower end of conduit is provided with screen pack.
Be further used as the improvement of technical solution of the present invention, in main body, in air admission hole, be provided with connector.
Be further used as the improvement of technical solution of the present invention, the bottom side of upper cover is provided with and fastens respectively internal layer and outer field draw-in groove.
Beneficial effect of the present invention: this refrigeration compressor adopts double-decker by double-deck directly air suction silencer main body, the structure of internal layer, skin and gas interlayer is arranged so that muffler is under less volume, better erasure effect can be provided, save material simultaneously, reduce costs, in addition, also improve the effect of heat insulation of muffler, thereby improved gettering efficiency.
Brief description of the drawings
Below in conjunction with accompanying drawing, the invention will be further described:
Fig. 1 is the cutaway view of the embodiment of the present invention;
Fig. 2 is the explosive view of the embodiment of the present invention;
Fig. 3 is the mounting structure figure of the embodiment of the present invention.
Detailed description of the invention
With reference to Fig. 1～Fig. 3, the invention provides double-deck directly air suction silencer for refrigeration compressor, comprise the upper cover 2 that is provided with the main body 1 of silencing cavity 11 and fastens with main body 1, upper cover 2 is provided with the conduit 21 stretching in silencing cavity 11, in main body 1, below conduit 21, be provided with air admission hole 15, main body 1 comprises internal layer 12 and skin 13, and internal layer 12 and outer 13 is spaced from each other and forms gas interlayer 14.
This refrigeration compressor with double-deck directly air suction silencer at work, working medium enters silencing cavity 11 from air admission hole 15, enter in the cylinder 6 of compressor along conduit 21 again, arranging of silencing cavity 11 reduces the noise that compressor produces due to working medium elliptical gear in breathing process, main body 1 in the present invention adopts double-decker, internal layer 12, even if the structure of skin 13 and gas interlayer 14 is arranged so that muffler is under less volume, better erasure effect also can be provided, the muffler structure setting of little volume, save material, reduce cost, for compressor miniaturization development provides basis, in addition, the heat that double-decker can more effective obstruct compressor movement is delivered in muffler, thereby effectively reduces compressor air suction temperature, has improved gettering efficiency.
As the preferred embodiment of the present invention, the porch, lower end of conduit 21 is provided with screen pack 3, and screen pack 3 can effectively avoid the impurity in working medium to enter cylinder, thereby improves the service life of equipment.
As the preferred embodiment of the present invention, in main body 1, in air admission hole 15, be provided with connector 4, can realize being closely connected fast of outside air intake duct 5 and main body 1 by connector 4.
As the preferred embodiment of the present invention, the bottom side of upper cover 2 is provided with the draw-in groove 22 that fastens respectively internal layer 12 and outer 13, and muffler structure of the present invention is simple, is easy to install, and can be applied in batches in actual production.
Certainly, the invention is not limited to above-mentioned embodiment, those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite without prejudice to spirit of the present invention, and the modification that these are equal to or replacement are all included in the application's claim limited range.
