Abstract
The invention discloses a double-layer direct inhaling silencer for a refrigeration compressor. The double-layer direct inhaling silencer for the refrigeration compressor is used in the field of compressors. The double-layer direct inhaling silencer for the refrigeration compressor comprises a body with a sound deadening cavity and an upper cover fastened with the body. The upper cover is provided with a conduit stretching into the sound deadening cavity, an air inlet is formed in the body below the conduit, the body comprises an inner layer and an outer layer, and the inner layer and the outer layer are separated from each other to form a gas separating layer. The body of the double-layer direct inhaling silencer for the refrigeration compressor adopts a double-layer structure, and the structural arrangement of the inner layer, the outer layer and the gas separating layer enables the silencer to be capable of providing a better sound deadening effect with a smaller size. Meanwhile, the double-layer direct inhaling silencer for the refrigeration compressor saves materials, and reduces cost, in addition, the heat insulation effect of the silencer is improved, and therefore inhaling efficiency is improved.
Description
Technical field
The present invention is used for compressor field, particularly relates to the direct air suction silencer of a kind of refrigeration compressor.
Background technique
Air suction silencer is applied in the hermetically sealed compressor, general employing heat-insulating property plastic materials is preferably made, being in order to reduce noise on the one hand, is in order to reduce the compressor heat to the heat effect of refrigeration agent, to improve the gettering efficiency of compressor on the other hand.
The main body of existing air suction silencer all adopts the single layer structure design, there is following problem in this structural design: (1) baffler noise elimination effect is general, need to strengthen erasure effect, must increase the baffler volume or increase the baffler wall thickness, this will cause the waste of the integrally-built change of compressor, material and the increase of cost; (2) baffler is single layer structure, and insulation effect is relatively poor, because motor compressor is in operation process, the movement heat of motor heats baffler easily, and the 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, the 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: the double-deck directly air suction silencer of refrigeration compressor, comprise the main body that is provided with silencing cavity and the loam cake that fastens with main body, on cover and be provided with the conduit that stretches in the silencing cavity, below conduit, be provided with inlet hole on the main body, main body comprises internal layer and skin, and internal layer and skin are spaced from each other and form the gas interlayer.
Be further used as the improvement of technical solution of the present invention, the ingress, lower end of conduit is provided with filter screen.
Be further used as the improvement of technical solution of the present invention, in inlet hole, be provided with connector on the main body.
Be further used as the improvement of technical solution of the present invention, the bottom side of loam cake is provided with and fastens internal layer and outer field draw-in groove respectively.
Beneficial effect of the present invention: this refrigeration compressor adopts double layer construction with double-deck directly air suction silencer main body, the structure of internal layer, skin and gas interlayer is arranged so that baffler is under littler volume, better erasure effect can be provided, save material simultaneously, reduce cost, in addition, also improve the effect of heat insulation of baffler, thereby improved gettering efficiency.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing:
Fig. 1 is the sectional view of the embodiment of the invention;
Fig. 2 is the explosive view of the embodiment of the invention;
Fig. 3 is the mounting structure figure of the embodiment of the invention.
Embodiment
With reference to Fig. 1～Fig. 3, the invention provides the double-deck directly air suction silencer of refrigeration compressor, comprise the main body 1 that is provided with silencing cavity 11 and the loam cake 2 that fastens with main body 1, loam cake 2 is provided with the conduit 21 that stretches in the silencing cavity 11, below conduit 21, be provided with inlet hole 15 on the main body 1, 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 inlet hole 15, enter in the cylinder of compressor 6 along conduit 21 again, arranging of silencing cavity 11 reduces the noise that compressor produces owing to working medium motion impact in breathing process, main body 1 among the present invention adopts double layer construction, internal layer 12, even if the structure of skin 13 and gas interlayer 14 is arranged so that baffler is under littler volume, also can provide better erasure effect, the muffler structure setting of little volume, then saved material, reduced cost, for compressor miniaturization development provides the basis; In addition, the heat that double layer construction can more effective obstruct compressor movement is delivered in the baffler, thereby effectively reduces the compressor air suction temperature, has improved gettering efficiency.
As the preferred embodiment of the present invention, the ingress, lower end of conduit 21 is provided with filter screen 3, and filter screen 3 can effectively avoid the impurity in the working medium to enter cylinder, thereby improves the working life of equipment.
As the preferred embodiment of the present invention, in inlet hole 15, be provided with connector 4 on the main body 1, can realize closely being connected fast of outside sucking pipe 5 and main body 1 by connector 4.
As the preferred embodiment of the present invention, the bottom side of loam cake 2 is provided with the draw-in groove 22 that fastens internal layer 12 and outer 13 respectively, and muffler structure of the present invention is simple, is easy to install, and can be applied in the actual production in batches.
Certainly, the invention is not limited to above-mentioned mode of execution, those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite of spirit of the present invention, the modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
