Embodiment
In order to make technological scheme of the present invention clearly, below in conjunction with accompanying drawing, compressor air suction structure of the present invention and compressor are described in further detail.Should be appreciated that specific embodiment described herein only in order to explain that the present invention is not intended to limit the present invention.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.
See Fig. 1 to Fig. 7, as shown in Figure 1, compressor air suction structure of the present invention comprises the radial gas-entered passageway 100 offered on cylinder 400, also being included in cylinder 400 inwall side is communicated with in the vertical suction passage 200 arranged along through cylinder 400 both ends of the surface that cylinder 400 axial direction is formed with gas-entered passageway 100, like this, the operations such as compression are carried out in the inside that the gas sucked from the sucking pipe of compressor enters cylinder 400 after gas-entered passageway 100 and suction passage 200.In the present embodiment, suction passage 200 is preferably through cylinder 400 both ends of the surface and the U-shaped channel slot in the cross section of vertical cylinder 400 axial direction, is increasing the volume of suction passage like this, and is being convenient to manufacturing.
The suction port 300 of suction passage 200 on cylinder 400 inwall is the rectangular air inlet along through cylinder 400 both ends of the surface that cylinder 400 axial direction is formed, rectangular air inlet is arranged near the vane slot 500 of cylinder 400, increase the compression angle of cylinder, improve the volumetric efficiency of compressor, reduce air-breathing turbulent flow.In the present embodiment, rectangular air inlet is preferably a rectangular opening that substantially horizontal is narrow, vertical direction is long.
The width of suction port 300 is less than the diameter of gas-entered passageway 100, and suction port 300 is placed between the line stretcher of radial edges line of gas-entered passageway 100.As shown in Figures 2 and 3, the end points of the line stretcher of two radial edges lines of gas-entered passageway 100 is labeled as A ', B ' respectively, and the end points of two edge lines of suction port is labeled as A, B respectively, and as can be seen from the figure, terminal A, B are placed in terminal A ', between B '.
Make the cylinder wall between suction port 300 and vane slot 500 leave thicker entity part like this, solve cylinder 400 and there is thin walled structures and yielding problem.While fully ensureing compressor air suction structure stability, still can close suction port in advance, ensure that compressor air suction reliability of structure, thus improve efficiency and the stability of compressor.
As further improvement, compressor air suction structure of the present invention is also included in the radial vent 600 offered on the cylinder wall between suction port 300 and vane slot 500, and vent 600 is communicated with gas-entered passageway 100.More preferably, on the axial direction of cylinder 400, namely on the thickness direction of cylinder, vent 600 is located at the middle part of the cylinder wall between suction port 300 and vane slot 500, so both can ensure compressor air suction reliability of structure and stability.Because the cylinder wall between suction port 300 and vane slot 500 has thicker entity part, what can increase cylinder 400 like this vacuumizes angle, thus affects the efficiency of compressor.By arranging the vent 600 that is communicated with gas-entered passageway 100, make in the breathing process of compressor, refrigerant can also enter cylinder 400 by vent 600, thus reduce compressor vacuumize angle, ensure that the efficiency of compressor.
As shown in Figures 5 to 7, what below in conjunction with accompanying drawing compressor air suction structure of the present invention is described vacuumizes power consumption:
Slide plate is provided with in general vane slot 500, when roller rolls in the active chamber of cylinder 400, slide plate makes its front end remain and roller cylindrical close contact under the action of the spring, thus the inner chamber of cylinder 400 is divided into air aspiration cavity and compression chamber two-part by the point of contact of the inwall of slide plate, roller and cylinder 400, the volume size of air aspiration cavity and compression chamber changes with the rotation of roller.
During compressor air suction, when seal point is before slide plate summit arrives cylinder air inlet leftmost edge, air aspiration cavity increases fast, but does not have gas make-up to arrive in this cavity.Now, this cavity is in the state of vacuumizing, as shown in Figure 6 and Figure 7.Wherein, vacuumizing region 700 needs consumption electric energy flog a dead horse thus affect the efficiency of compressor, and can produce noise.As shown in Figure 5, the compressor air suction structure of the present embodiment vacuumizes in the angular range of 10.3 ° (180 °-169.7 °=10.3 °), thus solve cylinder wall between suction port 300 and vane slot 500 blocked up cause vacuumize the excessive problem of angle.The compressor air suction structure of the present embodiment, by arranging the vent 600 be communicated with gas-entered passageway 100, even if increase the cylinder wall thickness between suction port 300 and vane slot 500, refrigerant also can enter cylinder from vent 600, thus solve compressor vacuumize the excessive problem of angle.
More preferably, at cylinder 400 in the radial direction, the cylinder wall between the through vane slot 500 of vent 600 and suction port 300, makes vent 600 be communicated with gas-entered passageway 100, be convenient to refrigerant enter in cylinder 400 from vent 600, thus reach the object reducing to vacuumize angle.In the present embodiment, vent 600 only penetrates the cylinder wall between vane slot 500 and suction port 300, and vent 600 can not touch the cylinder wall away from vane slot 500 one end, this ensure that the sealing of cylinder 400, thus ensure that the performance of compressor.
As a kind of embodiment, vent 600 is in circular arc vent or round vent.In the present embodiment, vent 600 can adopt circular knives machine shaping, as drill bit or milling cutter etc., makes vent 600 be convenient to processing like this.More preferably, vent 600 place diameter of a circle is less than the diameter of gas-entered passageway 100, namely the diameter of circular knives is less than the diameter of gas-entered passageway 100, vent 600 can be made so only to penetrate the entity part of the cylinder wall of vane slot 500 side, and the cylinder wall of suction port 300 the other end can not be touched.In other embodiments, the U-shaped hole of vent 600, the opening in U-shaped hole is towards suction port 300.Certainly, the shape of vent 600 can also be other shapes such as rectangle.
Present invention also offers a kind of compressor, comprise the compressor air suction structure of above-mentioned any embodiment.
Compressor air suction structure of the present invention and compressor, by suction port is set to rectangular air inlet, and the width of suction port is less than the diameter of gas-entered passageway, suction port is placed between the line stretcher of radial edges line of gas-entered passageway, the cylinder wall between suction port and vane slot is made to leave thicker entity part like this, solve cylinder and there is the yielding problem of thin walled structures, while fully ensureing compressor air suction structure stability, still can close suction port in advance, ensure that compressor air suction reliability of structure, thus improve efficiency and the stability of compressor.
The above embodiment only have expressed several mode of execution of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
