As shown in Figure 1 to Figure 3, the scroll compressor of the present invention includes that housing 1, the inner space of housing 1 are divided into suction space 11 (low-pressure side) and emission quotas 12 (high-pressure side).It is arranged on the suction space 11 of housing 1 for producing the motor 2 that drives of revolving force.Main frame 3 is fixedly mounted between the suction space 11 of housing 1 and emission quotas 12.Fixed eddy plate 4 is fixedly mounted on the upper surface of main frame 3.It is connected to drive being arranged between main frame 3 and fixed eddy plate around movable orbiting scroll 5 of crank axle 23 of motor 2 prejudicially.The discharge chambe (P) of a pair continuous moving is collectively formed around movable orbiting scroll 5 and fixed eddy plate 4.It is arranged on fixed eddy plate 4 and between movable orbiting scroll 5 for preventing around the cross slip-ring of the rotation of movable orbiting scroll 5.
Suction tube 13 is connected to the suction space 11 of housing 1 with in communication, and delivery pipe 14 is connected to the emission quotas 12 of housing 1 with in communication.
Although not showing in figure, but this housing sets Packed emission quotas, and this emission quotas is fixedly coupled to the exhaust chamber of fixed eddy plate 4 and is divided into suction space (low-pressure side) and emission quotas (high-pressure side).Or, the inner space of housing can be divided into suction space and emission quotas by height-low pressure separation end plate (not shown), and this height-low pressure separation end plate is fixed to the upper surface of fixed eddy plate, and attaches to the inner peripheral surface of housing.
The fixed scroll 42 that the fixed eddy plate 4 basal surface by end plate 41 with from end plate 41 stretches out is constituted, and fixed scroll 42 forms involute shape, in order to form compression together with around the moving scrollwork 52 of movable orbiting scroll 5
Room (P).Suction inlet (not shown) is formed so that the suction space 11 of housing 1 communicates with discharge chambe (P) on the outer peripheral face of the end plate 41 of fixed eddy plate 4.Central part at the end plate 41 of fixed eddy plate 4 forms floss hole 44 so that the emission quotas 12 of housing 1 communicates with discharge chambe (P).Unaccounted reference 7 represents subframe, and 8 represent drain valve, and 21 represent stator, and 22 represent rotor.
In the present invention, cold-producing medium is introduced into suction space 11 (low-pressure side of housing 1) from outside by suction tube 13.Then, suck low pressure refrigerant in space 11 and be introduced into fixed eddy plate 4 by the suction inlet of fixed eddy plate 4, the central part then being moved to around movable orbiting scroll and fixed eddy plate around movable orbiting scroll 5.Then, cold-producing medium 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 performed.
As shown in Figures 2 and 3, it is divided into two parts around movable orbiting scroll 5.More specifically, it is made up of the scroll wraps 50 engaged with fixed eddy plate and the base portion 60 being 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 discharge chambe by engaging with fixed scroll 42, and scrollwork flange 54 is integrally formed with moving scrollwork 52.Scrollwork flange 54 is shaped as, and is formed at the both sides of the basal surface of scrollwork flange 54 to be coupled to the keyed portion 56 of base portion 60.
Base portion 60 is coupled to scroll wraps 50 when towards the basal surface of scrollwork flange 54.More specifically, this base portion includes: base flange 64, and it is formed similarly to the dish type of scrollwork flange 54；And boss portion 68, it is formed on the basal surface of base flange 64 and is connected to crank axle 23.
Two edges of the upper surface of base flange 64 are respectively formed with the keyhole being connected to keyed portion 56.When keyed portion is inserted into keyhole, scroll wraps 50 may move along the direction of crank axle relative to base portion 60, but immovable along radial direction or the circumference of base portion 60.Scroll wraps 50 motion vertically is limited by the gap between fixed eddy plate and main frame 3.Therefore, keyed portion 56 remains inserted into the state of keyhole 66.More specifically, scroll wraps 50 and base portion 60 connection firmly with each other can be made by keyed portion is inserted keyhole, and without using being spirally connected or welding.
For preventing the cross slip-ring 6 rotated around movable orbiting scroll 5 to be coupled to the basal surface of base portion 60.More specifically, cross slip-ring 6 is provided with the ring part 6a that the basal surface with base flange 64 contacts.There are both sides that a pair first protuberance 6b of 180 (spending) phase contrast are formed at the basal surface of ring part 6a each other.First protuberance 6b inserts in the first protuberance groove 3a of main frame 3.There are both sides that a pair second protuberance 6c of 180 (spending) phase contrast are formed at the upper surface of ring part 6a each other.The second protuberance groove 64a that second protuberance 6c is inserted on the basal surface being formed at base flange 64.
Constructing based on these, even if the revolving force of crank axle 23 is passed to base portion 60, base portion 60 also can be prevented from the effect because of cross slip-ring 6 carrying out moving motion when rotating.And, it is connected to base portion 60 so that the scroll wraps 50 with the most confined motion also carries out moving motion together with base portion 60.
Forming back pressure chamber 62 at the middle part of the upper surface of base flange 64, the inner space of this back pressure chamber is separated by o-ring 62a.With reference to Fig. 4, back pressure chamber 62 is arranged between the basal surface of scrollwork flange 54 and the upper surface of base flange 64.The inner space of back pressure chamber 62 is separated by o-ring 62a being inserted and fixed base flange 64 with low-pressure side 11.Wearing on scrollwork flange 54 and be formed with back pressure hole 54a, the inner space of back pressure chamber 62 communicates with discharge chambe via this back pressure hole.
When sucking and compressing cold-producing medium, a part for the cold-producing medium compressed in discharge chambe is introduced into back pressure chamber via back pressure hole 54a.Because the interior pressure of back pressure chamber is higher than the circumferential pressure of base flange 64, so scroll wraps 50 is moved vertically from base portion 60.So can make can carry out between the basal surface of fixed eddy plate and moving scrollwork 52 seal operation.
Here, the intrinsic pressure of back pressure chamber can determine according to the position of back pressure hole.More specifically, when back pressure hole is shifted near during around the central part of the moving scrollwork 52 of movable orbiting scroll, and the internal pressure of back pressure chamber increases.On the other hand, when back pressure hole is towards the outer side shifting around the moving scrollwork 52 of movable orbiting scroll, the internal pressure of back pressure chamber reduces.
Fig. 5 A to Fig. 5 C is the plane graph schematically showing the process being compressed cold-producing medium by the moving scrollwork according to the first embodiment of the present invention and fixed scroll.Here, solid line is corresponding to the centrage of fixed scroll 42, and dotted line is corresponding to the centrage of moving scrollwork 52.Fig. 5 C is shown in the pressure of discharge chambe and reaches to start when discharging pressure the operation of discharge process.As it was previously stated, the pressure in the discharge chambe formed by moving scrollwork and fixed scroll changes during compression process continuously.Therefore, the pressure also consecutive variations on any point of moving scrollwork in a compression circulation.
Such as, during compression process when back pressure hole is in and is applied at the point of discharge pressure, the pressure identical with discharge pressure is applied to back pressure chamber.In the case, due to excessive back pressure, the thrust between basal surface and the moving scrollwork of fixed eddy plate is relatively big, therefore can cause big loss due to friction.Additionally, discharge pressure becomes different according to the difference of the amount of the compressive load being applied to compressor.Therefore, when back pressure hole is positioned at point " a " place being applied in discharge pressure, make thrust become different according to the difference of load.So can affect the performance of compressor.More specifically, point " a " is in the range of discharge beginning angle.
Point " b " represents that discharge pressure is applied with the position of a scheduled time, applies the intermediate pressure between suction pressure and discharge pressure in remaining time.Therefore, when back pressure hole is formed at point " b " place, suitable back pressure can be obtained.Even if additionally, discharge pressure is changed, due to the existence of this intermediate pressure due to reasons such as load changes, it is possible to and compensate this discharge pressure to a certain extent.So can reduce the impact of performance on compressor because load changes.Inventors have established that point " b " is in the involute phase contrast at the discharge beginning angle with moving scrollwork is in the range of 180 °.
Point " c " only applies the position of intermediate pressure during representing compression process.When back pressure hole is formed at point " c " place, back pressure is the lowest and the sealing property that is difficult to.Cold-producing medium so can be caused to leak.
Fig. 6 is to illustrate when back pressure hole is positioned at point " a " and point " b ", the figure of each thrust under the conditions of low-load, overload, High Pressure Difference and high pressure ratio.
With reference to Fig. 6, when back pressure hole is positioned at point " a ", the thrust produced under conditions of low-load is excessive, and the thrust under the conditions of corresponding has big deviation each other.On the other hand, when back pressure hole is positioned at point " b ", the thrust produced under low load conditions is less, and the thrust under the conditions of corresponding has little deviation each other.
Unlike first embodiment, as it is shown in fig. 7, cross slip-ring can be connected to fixed eddy plate 4.Fig. 7 is the sectional view illustrating scroll compressor according to the second embodiment of the present invention.With reference to Fig. 7, cross slip-ring 6 is arranged in the scroll wraps 50 of movable orbiting scroll, is more specifically arranged on the upper surface of scrollwork flange 54.To this end, form the first protuberance groove 4a the first protuberance 6b insertion for cross slip-ring 6 on the basal surface of fixed eddy plate 4.
Second protuberance (not shown) of cross slip-ring 6 is inserted into the second protuberance groove (not shown) of scrollwork flange 54.
Unlike the method shown in first embodiment and the second embodiment, scroll wraps and base portion can be coupled to each other by welding or use bolt.In the case, scroll wraps can be fixing, in order to immovable relative to base portion.And, cross slip-ring can be connected to the upper surface of scroll wraps or the basal surface of base portion.
Previous embodiment and advantage are only exemplary, are not necessarily to be construed as limitation of the present invention.The content taught can be easily applied to other kinds of device.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.Multiple features of exemplary embodiments described herein, structure, method and other characteristics can variously be combined obtaining other and/or alternative one exemplary embodiment.
