As shown in Figure 1 to Figure 3, scroll compressor of the present invention comprises housing 1, and the inner space of housing 1 is divided into suction space 11(low voltage side) and emission quotas 12(high pressure side).Be installed in the suction space 11 of housing 1 for generation of the drive motor 2 of rotating force.Main frame 3 is fixedly mounted between the suction space 11 and emission quotas 12 of housing 1.Fixed eddy plate 4 is fixedly mounted on the upper surface of main frame 3.Be connected to being installed between main frame 3 and the fixed eddy plate around movable orbiting scroll 5 of crankshaft 23 of drive motor 2 prejudicially.Around movable orbiting scroll 5 and the fixed eddy plate 4 common pressing chambers (P) that constitute a pair of continuous movement.Be used for preventing that cross slip ring around the rotation of movable orbiting scroll 5 is installed in fixed eddy plate 4 and between movable orbiting scroll 5.
Although not shown in the figures, this housing is provided with the emission quotas of sealing, and this emission quotas exhaust chamber of being fixedly coupled to fixed eddy plate 4 is divided into and sucks space (low voltage side) and emission quotas (high pressure side).Perhaps, the inner space of housing can be separated the end plate (not shown) by height-low pressure and is divided into suction space and emission quotas, and this height-low pressure is separated end plate and is fixed to the upper surface of fixed eddy plate, and attaches to the inner peripheral surface of housing.
Fixed eddy plate 4 constitutes by end plate 41 with from the fixed scroll 42 that the bottom surface of end plate 41 stretches out, and fixed scroll 42 forms involute shape, in order to form pressing chamber (P) with the moving scrollwork 52 around movable orbiting scroll 5.Form the suction port (not shown) on the outer circumferential face of the end plate 41 of fixed eddy plate 4, make the suction space 11 of housing 1 communicate with pressing chamber (P).Central part at the end plate 41 of fixed eddy plate 4 forms floss hole 44, makes the emission quotas 12 of housing 1 communicate with pressing chamber (P).Unaccounted reference character 7 expression subframes, 8 expression escape cocks, 21 expression stators, 22 expression rotors.
In the present invention, refrigeration agent is introduced into the low voltage side that sucks space 11(housing 1 from the outside by suction pipe 13).Then, the low pressure refrigerant in the suction space 11 is introduced into fixed eddy plate 4 by the suction port of fixed eddy plate 4, is moved to the central part around movable orbiting scroll and fixed eddy plate then around movable orbiting scroll 5.Then, refrigeration agent is compressed, and then is discharged into the emission quotas 12 of housing by the floss hole 44 of fixed eddy plate 4.These processes are repeatedly carried out.
As shown in Figures 2 and 3, but around movable orbiting scroll 5 separated into two parts.More specifically, formed by the scroll wraps 50 that engages with fixed eddy plate and the base portion 60 that is connected to scroll wraps 50 around movable orbiting scroll 5.Scroll wraps 50 has moving scrollwork 52 and scrollwork flange 54, and moving scrollwork 52 forms pressing chamber by engaging with fixed scroll 42, and scrollwork flange 54 is integrally formed with moving scrollwork 52.Scrollwork flange 54 forms dish type, and the key shape portion 56 that waits to be connected to base portion 60 is formed on the both sides of the bottom surface of scrollwork flange 54.
On two edges of the upper surface of base flange 64, be formed with the keyhole that is connected to key shape portion 56 respectively.When key shape portion was inserted into keyhole, scroll wraps 50 was removable with respect to base portion 60 along the direction of crankshaft, but along base portion 60 radially or circumferentially not movable.Scroll wraps 50 motion vertically is subjected to the restriction in the gap between fixed eddy plate and the main frame 3.Therefore, key shape portion 56 keeps being inserted into the state of keyhole 66.More specifically, can scroll wraps 50 and base portion 60 be connected each other securely by key shape portion being inserted keyhole, be spirally connected or weld and need not to utilize.
Be used for preventing that the cross slip ring 6 around movable orbiting scroll 5 rotations is coupled to the bottom surface of base portion 60.More specifically, cross slip ring 6 is provided with the ring part 6a that contacts with the bottom surface of base flange 64.Having the 180(degree each other) a pair of first protuberance 6b of phase difference is formed on the both sides of the bottom surface of ring part 6a.The first protuberance 6b inserts among the first protuberance groove 3a of main frame 3.Having the 180(degree each other) a pair of second protuberance 6c of phase difference is formed on the both sides of the upper surface of ring part 6a.The second protuberance 6c is inserted into the second protuberance groove 64a on the bottom surface that is formed on base flange 64.
Based on these structures, even the rotating force of crankshaft 23 is passed to base portion 60, carry out the moving motion under the state that base portion 60 also can be prevented from rotating in the effect because of cross slip ring 6.And, be connected to base portion 60 in order to have the scroll wraps 50 of radially confined motion and also carry out the moving motion with base portion 60.
Middle part at the upper surface of base flange 64 forms back pressure chamber 62, and the inner space of this back pressure chamber is separated by O type ring 62a.With reference to Fig. 4, back pressure chamber 62 is arranged between the upper surface of the bottom surface of scrollwork flange 54 and base flange 64.The O type ring 62a that inserts and be fixed to base flange 64 separates inner space and the low voltage side 11 of back pressure chamber 62.Wear in base flange 64 and to be formed with back pressure hole 64a, the inner space of back pressure chamber 62 communicates with pressing chamber via this back pressure hole.
When suction and compressed refrigerant, the part of compressed refrigeration agent is introduced into back pressure chamber via back pressure hole 54a in pressing chamber.Because the internal pressure of back pressure chamber is higher than the circumferential pressure of base flange 64, so base portion 60 moves vertically from scroll wraps 50.Can make like this between the bottom surface of fixed eddy plate and the moving scrollwork 52 and can carry out seal operation.
Here, the interior pressure of back pressure chamber can be determined according to the position of back pressure hole.More specifically, shift near around the central part of the moving scrollwork 52 of movable orbiting scroll the time when back pressure hole, the internal pressure of back pressure chamber increases.On the other hand, when back pressure hole towards around the outer side shifting of the moving scrollwork 52 of movable orbiting scroll the time, the internal pressure of back pressure chamber reduces.
Fig. 5 A is schematically illustrated by the planimetric map according to the process of the moving scrollwork of the first embodiment of the present invention and fixed scroll compressed refrigerant to Fig. 5 C.Here, solid line is corresponding to the center line of fixed scroll 42, and dotted line is corresponding to the center line of moving scrollwork 52.The pressure that Fig. 5 C is illustrated in pressing chamber begins the operation of discharge process when reaching discharge pressure.As previously mentioned, the pressure in the pressing chamber that is formed by moving scrollwork and fixed scroll changes during compression process continuously.Therefore, the pressure on any point of moving scrollwork also changes continuously in a compression cycle.
For example, during the compression process when back pressure hole is in the some place that is applied in discharge pressure, the pressure identical with discharge pressure is applied to back pressure chamber.In the case, because excessive back pressure, the thrust between the bottom surface of fixed eddy plate and the moving scrollwork is bigger, therefore can be owing to friction causes big loss.In addition, discharge pressure dissimilates according to the difference of the amount of the compressive load that is applied to compressor.Therefore, when back pressure hole is positioned at the point " a " when locating that is applied in discharge pressure, according to the difference of load thrust is dissimilated.Can influence the performance of compressor like this.More specifically, point " a " is in the scope at discharging beginning angle.
Point " b " expression discharge pressure has applied the position of a scheduled time, applies intermediate pressure between suction pressure and discharge pressure in all the other times.Therefore, when back pressure hole is formed on point " b " when locating, can obtain suitable back pressure.In addition, though discharge pressure because load variations etc. is former thereby be changed because the existence of this intermediate pressure, also can and compensate this discharge pressure to a certain extent.Can reduce like this because of the Effect on Performance of load change to compressor.The inventor has confirmed that it is in 180 ° the scope that point " b " is in involute phase difference that discharging with the moving scrollwork begins the angle.
Only apply the position of intermediate pressure during point " c " the expression compression process.When back pressure hole is formed on point " c " when locating, the too low and sealability that is difficult to realize of back pressure.Can cause refrigeration agent to leak like this.
Fig. 6 illustrates when back pressure hole is positioned at point " a " and point " b ", the figure of each thrust under low load, overload, High Pressure Difference and high pressure ratio condition.
With reference to Fig. 6, when back pressure hole was positioned at point " a ", the thrust that produces under the condition of low load was excessive, and the thrust under corresponding condition has big deviation each other.On the other hand, when back pressure hole was positioned at point " b ", the thrust that produces under low loading condition was less, and the thrust under corresponding condition has little deviation each other.
Different with first embodiment is that as shown in Figure 7, the cross slip ring can be connected to fixed eddy plate 4.Fig. 7 is the sectional view that scroll compressor according to a second embodiment of the present invention is shown.With reference to Fig. 7, cross slip ring 6 is installed on the scroll wraps 50 of movable orbiting scroll, more specifically is installed in the upper surface of scrollwork flange 54.For this reason, the bottom surface at fixed eddy plate 4 forms the first protuberance groove 5a for the first protuberance 6b insertion of cross slip ring 6.
The second protuberance (not shown) of cross slip ring 6 is inserted into the second protuberance groove (not shown) of scrollwork flange 54.
Different with the method shown in first embodiment and second embodiment is that scroll wraps and base portion can or use bolt to be coupled to each other by welding.In the case, scroll wraps can be fixed, so that not movable with respect to base portion.And the cross slip ring can be connected to the upper surface of scroll wraps or the bottom surface of base portion.
Previous embodiment and advantage only are exemplary, should not be interpreted as limitation of the present invention.The content of institute's teaching can easily be applied to the device of other types.This specification is intended to annotate, and the scope of unrestricted claims.Many replacement schemes, change and modification will be apparent to those skilled in the art.A plurality of features of one exemplary embodiment described herein, structure, method and other characteristics can make up to obtain other and/or alternative one exemplary embodiment by variety of way.
