Embodiment
In order that technical scheme is clearer, below in conjunction with accompanying drawing, to the compressor air suction structure of the present invention
And compressor is described in further detail.It should be appreciated that specific embodiment described herein only to explain the present invention simultaneously
It is not used in the restriction present invention.It should be noted that in the case where not conflicting, the spy in embodiment and embodiment in the application
Sign can be mutually combined.
Referring to Fig. 1 to Fig. 7, as shown in figure 1, the compressor air suction structure of the present invention includes what is radially opened up on cylinder 400
Inlet channel 100, in addition to the both ends of the surface of insertion cylinder 400 formed in the inwall side of cylinder 400 along the axial direction of cylinder 400 with
The connection of inlet channel 100 is in the suction passage 200 being vertically arranged, and so, the gas sucked from the air intake duct of compressor is through air inlet
The operation such as it is compressed into the inside of cylinder 400 after passage 100 and suction passage 200.In the present embodiment, suction passage 200
The preferably U-shaped channel slot in the section of the insertion both ends of the surface of cylinder 400 and the axial direction of vertical cylinder 400, is so being increased
The volume of suction passage, and be easy to fabricate.
Air inlet 300 of the suction passage 200 on the inwall of cylinder 400 is the insertion formed along the axial direction of cylinder 400
The rectangular air inlet of the both ends of the surface of cylinder 400, rectangular air inlet are set close to the vane slot 500 of cylinder 400, increase the pressure of cylinder
Contracting angle, the volumetric efficiency of compressor is improved, reduce air-breathing turbulent flow.In the present embodiment, rectangular air inlet is preferably one
Horizontal direction is narrow, the rectangular opening of vertical direction length.
The width of air inlet 300 is less than the diameter of inlet channel 100, and air inlet 300 is placed in the longitudinal edge of inlet channel 100
Between the extension line of edge line.As shown in Figures 2 and 3, the end points difference of the extension line of two radial edges lines of inlet channel 100
Labeled as A ', B ', the end points of two edge lines of air inlet is respectively labeled as A, B, it can be seen that terminal A, B are placed in
Terminal A ', between B '.
So cause the cylinder wall between air inlet 300 and vane slot 500 to leave thicker entity part, solve cylinder
400 thin-wall construction be present and it is yielding the problem of.While compressor air suction structural stability is fully ensured that, it still is able to shift to an earlier date
Air inlet is closed, compressor air suction reliability of structure is ensure that, so as to improve the efficiency of compressor and stability.
As a further improvement, compressor air suction structure of the invention be additionally included in air inlet 300 and vane slot 500 it
Between cylinder wall on the passage 600 that radially opens up, passage 600 connects with inlet channel 100.More preferably, in cylinder 400
On axial direction, i.e., on the thickness direction of cylinder, passage 600 is positioned at the cylinder between air inlet 300 and vane slot 500
The middle part of wall, it so can both ensure compressor air suction reliability of structure and stability.Due to air inlet 300 and vane slot
Cylinder wall between 500 has thicker entity part, and can so increase cylinder 400 vacuumizes angle, so as to influence to compress
The efficiency of machine.By setting the passage 600 connected with inlet channel 100 so that in the breathing process of compressor, refrigerant is also
Cylinder 400 can be entered by passage 600, so as to which reduce compressor vacuumizes angle, ensure that the efficiency of compressor.
As shown in Figures 5 to 7, power consumption is vacuumized below in conjunction with brief description of the drawings compressor air suction structure of the invention：
Slide plate is provided with general vane slot 500, when roller rolls in the working chamber of cylinder 400, slide plate is in spring
In the presence of make its front end remain with the cylindrical close contact of roller, so as to slide plate, roller and cylinder 400 inwall point of contact
The inner chamber of cylinder 400 is divided into suction muffler and compression chamber two parts, the volume size of suction muffler and compression chamber turns with roller
Move and change.
During compressor air suction, before seal point reaches cylinder air inlet leftmost edge by slide plate summit, suction muffler is fast
Speed increase, but no gas is added in this cavity.Now, the cavity is in and vacuumizes state, as shown in Figure 6 and Figure 7.
Wherein, vacuumizing region 700 needs consumption electric energy to flog a dead horse so as to influence the efficiency of compressor, and can produce noise.Such as
Shown in Fig. 5, the compressor air suction structure of the present embodiment is taken out very in the angular range of 10.3 ° (180 ° -169.7 °=10.3 °)
Sky, so as to solve the problems, such as that to vacuumize angle excessive caused by the cylinder wall between air inlet 300 and vane slot 500 is blocked up.
The compressor air suction structure of the present embodiment, by setting the passage 600 connected with inlet channel 100, even if increasing air inlet
Cylinder wall thickness between mouth 300 and vane slot 500, refrigerant can also enter cylinder from passage 600, so as to solve compression
Machine vacuumizes the problem of angle is excessive.
More preferably, in cylinder 400 in the radial direction, passage 600 is penetrated between vane slot 500 and air inlet 300
Cylinder wall so that passage 600 connects with inlet channel 100, is easy to refrigerant to be entered from passage 600 in cylinder 400, so as to
Reach the purpose for reducing and vacuumizing angle.In the present embodiment, passage 600 is only penetrated between vane slot 500 and air inlet 300
Cylinder wall, and passage 600 will not touch the cylinder wall away from the one end of vane slot 500, this ensure that the sealing of cylinder 400
Property, so as to ensure that the performance of compressor.
As a kind of embodiment, passage 600 is in circular arc passage or round vent.In the present embodiment,
Passage 600 can use circular knives machine-shaping, such as drill bit or milling cutter, so that passage 600 is easy to process.Compared with
Excellently, the place diameter of a circle of passage 600 is less than the diameter of inlet channel 100, i.e. the diameter of circular knives is less than inlet channel
100 diameter, passage 600 can be so caused only to penetrate the entity part of the cylinder wall of the side of vane slot 500, without touching
The cylinder wall of the other end of air inlet 300.In other embodiments, 600 U-shaped hole of passage, the opening in U-shaped hole is towards air inlet
300.Certainly, the shape of passage 600 can also be the other shapes such as rectangle.
Present invention also offers the compressor air suction structure of a kind of compressor, including any of the above-described embodiment.
The compressor air suction structure and compressor of the present invention, by the way that air inlet is arranged into rectangular air inlet, and air inlet
Width be less than the diameter of inlet channel, air inlet is placed between the extension line of radial edges line of inlet channel, so that
Cylinder wall between air inlet and vane slot leaves thicker entity part, solves cylinder and has that thin-wall construction is yielding to ask
Topic, while compressor air suction structural stability is fully ensured that, still is able to close air inlet in advance, ensure that compressor air suction
Reliability of structure, so as to improve the efficiency of compressor and stability.
Embodiment described above only expresses the several embodiments of the present invention, and its description is more specific and detailed, but simultaneously
Therefore the limitation to the scope of the claims of the present invention can not be interpreted as.It should be pointed out that for one of ordinary skill in the art
For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the guarantor of the present invention
Protect scope.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
