Embodiment
It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.
As depicted in figs. 1 and 2, according to first embodiment of the invention, provide a kind of compressor pump, compressor pump comprises upper flange 10, cylinder 20, lower flange 30 and air intake passage 50.Cylinder 20 is arranged at the below of upper flange 10.Air intake passage 50 is opened in upper flange 10 and is communicated with upper flange 10 and cylinder 20 with on cylinder 20, and the axis of at least part of air intake passage 50 and the axis of cylinder 20 be obliquely installed.Lower flange 30 is positioned at the below of cylinder 20 and is connected with cylinder 20.
In the present embodiment, upper flange 10 and cylinder 20 offer the air intake passage 50 be interconnected, wherein, the axis of at least part of air intake passage 50 and the axis of cylinder 20 are obliquely installed.Upper flange 10 and cylinder 20 are provided with air intake passage 50, and during compressor operating, refrigerant by upper flange 10 and cylinder 20, then enters the air aspiration cavity of cylinder 20 successively.Be arranged so that compressor pump like this by air intake passage 50 from upper flange air-breathing, again because the axis of at least part of air intake passage 50 and the axis of cylinder 20 are obliquely installed, effectively decrease the inhalation resistance of compressor pump, thus add the power of compressor pump.
As shown in Figures 3 to 5, air intake passage 50 comprises the first suction port 51 and the second suction port 52.First suction port 51 is penetratingly arranged on upper flange 10.Second suction port 52 to be opened on cylinder 20 and to be connected with the first suction port 51.Wherein, the axis of the first suction port 51 is obliquely installed relative to the axis of cylinder 20.The effect can played equally and reduce cylinder 20 inhalation resistance is set like this.
In the second embodiment of the present invention, the axis of the second suction port 52 is obliquely installed relative to the axis of cylinder 20.Arrange like this can play equally with in embodiment one by same technique effect that the axis of the first suction port 51 is obliquely installed relative to the axis of cylinder 20.
In the third embodiment of the present invention, air intake passage 50 comprises the first suction port 51 and the second suction port 52.First suction port 51 is penetratingly arranged on upper flange 10.Second suction port 52 to be opened on cylinder 20 and to be connected with the first suction port 51.Wherein, the axis of the first suction port 51 and the second suction port 52 is obliquely installed relative to the axis of cylinder 20.The axis of two suction ports is all arranged to tilt, the effective like this inhalation resistance that create a further reduction cylinder 20, thus add the performance of compressor.
Preferably, the first suction port 51 is identical with the tilt angle of cylinder 20 with the second suction port 52 with the tilt angle of cylinder 20.Because the tilt angle of the axis of suction port is identical, make cylinder 20 air-breathing more smooth and easy, serve the effect of the inhalation resistance effectively reducing cylinder 20.
Preferably, the axis of the first suction port 51 is obliquely installed relative to the axis of cylinder 20 and tilt angle is α, wherein, and 30 °≤α≤60 °.
Preferably, the axis of the second suction port 52 is obliquely installed relative to the axis of cylinder 20 and tilt angle is θ, 30 °≤θ≤60 °.
In the present invention, if tilt angle is too small, namely too vertical, then when can cause compressor air suction, in air intake passage 50, there is more serious suction eddy phenomenon, thus make compressor produce extra power consumption.If tilt angle is excessive, the seal distance of the joint of the air intake passage 50 in upper flange 10 and cylinder 20 can be caused too small.So when angle of inclination controls at 30 ° to 60 °, compressor performance is in the optimum state.
In the fourth embodiment of the present invention, the axis of the first suction port 51 is obliquely installed relative to the axis of cylinder 20, and the axis of the second suction port 52 parallels with the axis of cylinder 20.Namely the first suction port 51 is inclined hole, and the second suction port 52 is straight hole.
In the fifth embodiment of the present invention, the axis of the first suction port 51 parallels with the axis of cylinder 20, and the axis of the second suction port 52 is obliquely installed relative to the axis of cylinder 20.Namely the first suction port 51 is straight hole, and the second suction port 52 is inclined hole.
The effect playing the inhalation resistance effectively reducing cylinder 20 that the set-up mode of the suction port in above-described embodiment four and embodiment four or five is same.
Wherein, compressor pump also comprises roller 40, roller 40 is arranged in cylinder 20, the external diameter of roller 40 is R1, the internal diameter of roller 40 is R2, and the distance at the center of the axis hole 12 of the Kong Bianzhi upper flange 10 of the first suction port 51 near the center of the axis hole 11 of upper flange 10 is L, and the internal diameter of cylinder 20 is R3, wherein, L-R3+R1-R2 >=0.5mm.Arrange like this and ensure that the problem of gas blowby leakage operationally can not occur compressor.If L-R3+R1-R2 < 0, the intakeport of upper flange 10 directly can be communicated with the inner circle of roller 40, if both are communicated with, will cause that gas blowby occurs and reveal.Namely L-R3+R1-R2 is at least greater than zero, compressor operating is got up L-R3+R1-R2 >=0.5mm safer.
As shown in Figure 2, cylinder 20 has protruding 60 towards the side of upper flange 10, and protruding 60 abut to form sealed department with upper flange 10.Sealed department and upper flange 10 joint form seal distance S, and the thickness of the projection 60 namely in figure is S.As shown in Figure 2, the zone of high pressure that Tu Zhong C district represents, D district is that the inside of air intake passage 50 is in low pressure area, and in order to ensure the Security of whole compressor pump body structure, C district and D district must have certain thickness sealed department and ensure the intensity of pump body structure and the performance of compressor.In order to play better Security and performance, the sealed department i.e. thickness S of projection 60 is arranged to S >=2mm.Such setting effectively prevent the possibility of compressor generation gas blowby and gas leakage.
As can be seen from the above description, the above embodiments of the present invention achieve following technique effect:
Apply technological scheme of the present invention, upper flange and cylinder offer the air intake passage be interconnected, wherein, the axis of at least part of air intake passage and the axis of cylinder are obliquely installed.Be arranged so that compressor pump like this by air intake passage from upper flange air-breathing, again because the axis of at least part of air intake passage and the axis of cylinder are obliquely installed, effectively decrease the inhalation resistance of compressor pump, thus add the power of compressor pump.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
