Embodiment
Below with reference to accompanying drawing and combine embodiment to specify the utility model.
Shown in Fig. 2 to 4, the scroll compressor according to the utility model comprises housing, and quiet wrap component 1 and upper bracket 6, and quiet wrap component 1 is fixedly installed on enclosure interior with upper bracket 6; Moving wrap component 4; Be arranged on the upper bracket 6 and the formation compression chamber that matches with quiet wrap component 1; Moving wrap component 4 is driven by the bent axle 7 that the motor that is arranged on enclosure interior 8 drives, and the side of quiet wrap component 1 is provided with the suction port 2 that is communicated with compression chamber, and the refrigerant that from suction port 2, sucks is compressed in compression chamber; Shown in Fig. 5 a; Also be provided with on the quiet wrap component 1 and be communicated with suction port 2 and towards the bypass passageways 3 of upper bracket 6, scroll compressor when work, from intakeport introduce air-breathing; A part is through in the gap between bypass passageways 3 entering upper brackets 6 and the moving wrap component 4; The refrigerant of low-temp low-pressure can absorb the frictional heat that moving wrap component 4 motions produce effectively, reduces the temperature of other component between moving wrap component 4 and moving wrap component 4 and the upper bracket 6, prevents the compressor component distortion that high temperature causes.
As shown in Figure 2, motor 8 drives bent axle 7 and rotates, and bent axle 7 drives moving wrap component 4 again and makes revolution motion around quiet wrap component 1; So formed a series of crescent-shaped spaces at moving wrap component 4 and 1 of quiet wrap component, along with the outer ring crescent-shaped space constantly moves to the center, at this moment; Refrigerant is pushed to central space gradually; Its volume constantly dwindles and pressure constantly raises, and until communicating with the central row pore, refrigerant is discharged from compression chamber.
Moving wrap component 4 has the trend around its center rotation under the gas force effect, this trend has been destroyed the proper functioning of scroll compressor, must limit.Cross slip ring 5 is arranged on the anti-rotation mechanism between moving wrap component 4 and the upper bracket 6; Cross slip ring 5 is provided with the protruding 5a of moving wrap component 4 rotations of restriction; Upper bracket 6 is provided with the corresponding keyway 6a with protruding 5a; The corresponding setting with keyway 6a of the outlet end of bypass passageways 3, promptly the bypass flow in the bypass passageways 3 directly gets into keyway 6a, thereby takes away the frictional heat of protruding 5a and keyway 6a.The refrigerant of introducing a part of low-temp low-pressure through bypass reduces the frictional heat of cross slip ring; Simultaneously because the linear reciprocating motion of cross slip ring causes the refrigerant fluctuation; Make the refrigerant after heating up to get into compression chamber through this bypass passageways fast, discharge after compression.
Shown in Fig. 6 a and 6b; Cross slip ring 5 is provided with a plurality of protruding 5a; Upper bracket 6 is provided with the corresponding keyway 6a of a plurality of and protruding 5a, and preferably, bypass passageways 3 is provided with a plurality of outlets corresponding respectively with a plurality of keyway 6a; A plurality of outlets are connected through drainage trough 3b, and the refrigerant of low-temp low-pressure can be cooled off each position that mainly rubs of cross slip ring 5.Drainage trough 3b is along the circumferential setting of quiet wrap component 1, and is communicated with compression chamber.Shown in Fig. 5 b, bypass passageways 3 is provided with the second outlet 3a, and the second outlet 3a is communicated with other outlets through drainage trough 3b.
The shape of cross section of bypass passageways 3 is not limit, and for the ease of processing, preferably, bypass passageways 3 is set to circular hole.Through setting up bypass passageways 3, can make the temperature of cross slip ring 5 compare the temperature reduction 10%-30% when not offering bypass passageways 3.
From above description, can find out that the utility model the above embodiments have realized following technique effect:
Scroll compressor according to the utility model; Be provided with the bypass passageways that is communicated with suction port through quiet wrap component; Scroll compressor is when work; From intakeport introduce air-breathing, a part gets in the gap between upper bracket and the moving wrap component through bypass passageways, the refrigerant of low-temp low-pressure can absorb the frictional heat of moving wrap component motion generation effectively; Reduce the temperature of other component between moving wrap component and moving wrap component and the upper bracket, prevent the compressor component distortion that high temperature causes.Through setting up bypass passageways, can make the temperature of cross slip ring compare the temperature reduction 10%-30% when not offering bypass passageways.
The preferred embodiment that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
