Specific implementation mode
In order to keep technical scheme of the present invention clearer, below in conjunction with attached drawing, to the compressor air suction structure of the present invention
And compressor is described in further detail.It should be appreciated that it is described herein specific examples are only used to explain the present invention simultaneously
It is not used in the restriction present invention.It should be noted that in the absence of conflict, the spy in embodiment and embodiment in the application
Sign can be combined with each other.
Referring to Fig. 1 to Fig. 7, as shown in Figure 1, the compressor air suction structure of the present invention includes radially being opened up on cylinder 400
Inlet channel 100 further includes 400 both ends of the surface of perforation cylinder that are formed along 400 axial direction of cylinder in 400 inner wall side of cylinder with
The connection of inlet channel 100 is in the suction passage 200 being vertically arranged, in this way, the gas sucked from the air intake duct of compressor is through air inlet
Inside behind channel 100 and suction passage 200 into cylinder 400 carries out the operation such as compressing.In the present embodiment, suction passage 200
The preferably U-shaped channel slot in the section of perforation 400 both ends of the surface of cylinder and 400 axial direction of vertical cylinder, is increasing in this way
The volume of suction passage, and manufacture easy to process.
Air inlet 300 of the suction passage 200 on 400 inner wall of cylinder is the perforation formed along 400 axial direction of cylinder
The rectangular air inlet of 400 both ends of the surface of cylinder, rectangular air inlet are arranged close to the sliding vane groove 500 of cylinder 400, increase the pressure of cylinder
Contracting angle improves the volumetric efficiency of compressor, reduces air-breathing turbulent flow.In the present embodiment, rectangular air inlet is preferably one
The rectangular opening that horizontal direction is narrow, vertical direction is grown.
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 endpoint difference of the extension line of two radial edges lines of inlet channel 100
Labeled as A ', B ', the endpoint of two edge lines of air inlet is respectively labeled as A, B, it can be seen from the figure that terminal A, B are placed in
Terminal A ', between B '.
In this way so that the cylinder wall between air inlet 300 and sliding vane groove 500 solves cylinder there are thicker entity part
400 have thin-wall construction and yielding.While fully ensuring that compressor air suction structural stability, it still is able to shift to an earlier date
Air inlet is closed, compressor air suction reliability of structure is ensure that, to improve the efficiency and stability of compressor.
As a further improvement, compressor air suction structure of the invention further include air inlet 300 and sliding vane groove 500 it
Between cylinder wall on the venthole 600 that radially opens up, venthole 600 is connected to inlet channel 100.More preferably, in cylinder 400
On axial direction, i.e., on the thickness direction of cylinder, venthole 600 is located at the cylinder between air inlet 300 and sliding vane groove 500
The middle part of wall can both ensure compressor air suction reliability of structure and stability in this way.Due to air inlet 300 and sliding vane groove
Cylinder wall between 500 has thicker entity part, and can increase cylinder 400 in this way vacuumizes angle, to influence to compress
The efficiency of machine.By the way that the venthole 600 being connected to inlet channel 100 is arranged so that in the breathing process of compressor, refrigerant is also
Cylinder 400 can be entered by venthole 600, angle is vacuumized to reduce compressor, ensure that the efficiency of compressor.
As shown in Figures 5 to 7, power consumption is vacuumized below in conjunction with the compressor air suction structure of the description of the drawings present invention：
It is provided with slide plate in general sliding vane groove 500, when roller rolls in the working chamber of cylinder 400, slide plate is in spring
Under the action of make its front end remain with roller outer circle be in close contact, to slide plate, roller and cylinder 400 inner wall point of contact
The inner cavity 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
It moves and changes.
When compressor air suction, before seal point reaches cylinder air inlet leftmost edge by slide plate vertex, suction muffler is fast
Speed increases, but no gas adds in this cavity.At this point, the cavity, which is in, vacuumizes state, as shown in Figure 6 and Figure 7.
Wherein, vacuumizing region 700 needs consumption electric energy to flog a dead horse to influence the efficiency of compressor, and will 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, to solve the problems, such as that vacuumize angle excessive caused by the cylinder wall between air inlet 300 and sliding vane groove 500 is blocked up.
The compressor air suction structure of the present embodiment, by the way that the venthole 600 being connected to inlet channel 100 is arranged, even if increasing air inlet
Cylinder wall thickness between mouth 300 and sliding vane groove 500, refrigerant can also enter cylinder from venthole 600, to solve compression
Machine vacuumizes the excessive problem of angle.
More preferably, cylinder 400 in the radial direction, venthole 600 penetrates through between sliding vane groove 500 and air inlet 300
Cylinder wall so that venthole 600 is connected to inlet channel 100, is entered in cylinder 400 from venthole 600 convenient for refrigerant, to
Achieve the purpose that reduce and vacuumizes angle.In the present embodiment, venthole 600 only penetrates between sliding vane groove 500 and air inlet 300
Cylinder wall, and venthole 600 will not touch the cylinder wall far from 500 one end of sliding vane groove, this ensure that the sealing of cylinder 400
Property, to ensure that the performance of compressor.
As a kind of embodiment, venthole 600 is arc-shaped venthole or round vent.In the present embodiment,
Circular knives machine-shaping, such as drill bit or milling cutter may be used in venthole 600, so that venthole 600 is easy to process.Compared with
Excellently, 600 place diameter of a circle of venthole is less than the diameter of inlet channel 100, i.e. the diameter of circular knives is less than inlet channel
100 diameter can make venthole 600 only penetrate the entity part of the cylinder wall of 500 side of sliding vane groove, without touching in this way
The cylinder wall of 300 other end of air inlet.In other embodiments, 600 U-shaped hole of venthole, the opening in U-shaped hole is towards air inlet
300.Certainly, the shape of venthole 600 can also be the other shapes such as rectangle.
The present invention also provides the compressor air suction structures of a kind of compressor, including any of the above-described embodiment.
The compressor air suction structure and compressor of the present invention, by setting air inlet to 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 sliding vane groove solves cylinder and asks there are thin-wall construction is yielding there are thicker entity part
Topic, while fully ensuring that compressor air suction structural stability, still is able to close air inlet in advance, ensure that compressor air suction
Reliability of structure, to improve the efficiency and stability of compressor.
Several embodiments of the invention above described embodiment only expresses, the description thereof is more specific and detailed, but simultaneously
Cannot the limitation to the scope of the claims of the present invention therefore be interpreted as.It should be pointed out that for those 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 range.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
