First total structure and the running principle of scroll compressor are described with reference to Fig. 1.As shown in Figure 1, scroll compressor 100 (hereinafter sometimes also can be called compressor) generally comprises housing 110.Housing 110 can comprise general cylindrical shape body 111, be arranged on body 111 one end top cover 112, be arranged on body 111 the other end bottom 114 and be arranged between top cover 112 and body 111 the inner space of compressor to be separated into the dividing plate 116 of high pressure side and low voltage side.Formation high pressure side, space between dividing plate 116 and top cover 112, and dividing plate 116, space between body 111 and bottom 114 form low voltage side.Low voltage side being provided with the air input joint 118 for sucking fluid, being provided with the exhaust joint 119 for the fluid after discharging compression in high pressure side.The motor 120 be made up of stator 122 and rotor 124 is provided with in housing 110.Live axle 130 is provided with to drive by the compressing mechanism determined scroll element 150 and dynamic scroll element 160 and formed in rotor 124.Dynamic scroll element 160 comprises end plate 164, is formed in the hub portion 162 of end plate 164 side and is formed in the spiral helicine blade 166 of end plate 164 opposite side.Determine scroll element 150 to comprise end plate 154, be formed in the spiral helicine blade 156 of end plate 154 side and be formed in the recess 158 of end plate 154 opposite side.Relief opening 152 is formed in the substantial middle position of end plate 154.Space around relief opening 152 also forms high pressure side.Compression chamber from radial outside to radially inner side C1, C2 and C3 of determining to be formed between the helical blade 156 of scroll element 150 and the helical blade 166 of dynamic scroll element 160 a series of volume and reducing gradually from.Wherein, the compression chamber C1 of outermost radial outside is in pressure of inspiration(Pi), and the compression chamber C3 of radial inner side is in exhaust pressure.Middle compression chamber C2 is between pressure of inspiration(Pi) and exhaust pressure, thus is also referred to as middle pressure chamber.
The side of dynamic scroll element 160 is supported by the top (i.e. supporting portion) of main bearing seat 140, and one end of live axle 130 is supported by the main bearing 144 be arranged in main bearing seat 140.One end of live axle 130 is provided with eccentric crank pin 132, is provided with and unloads lining 142 between eccentric crank pin 132 and the hub portion 162 of dynamic scroll element 160.By the driving of motor 120, dynamic scroll element 160 will relative to determining scroll element 150 translation rotation (namely, the central axis of dynamic scroll element 160 rotates around the central axis determining scroll element 150, but dynamic scroll element 160 itself can not rotate around the central axis of self) to realize the compression of fluid.Above-mentioned translation rotation is realized by the cross slip-ring 180 determining to arrange between scroll element 150 and dynamic scroll element 160.Fluid after determining scroll element 150 and dynamic scroll element 160 compression is discharged to high pressure side by relief opening 152.In order to prevent on high-tension side fluid to be back to low voltage side via relief opening 152 under specific circumstances, one-way valve or outlet valve 170 can be set at relief opening 152 place.
In order to realize the compression of fluid, determine to need effective sealing between scroll element 150 and dynamic scroll element 160.
On the one hand, determine to need axial seal between the top of the helical blade 156 of scroll element 150 and the end plate 164 of dynamic scroll element 160 and between the top of the helical blade 166 of dynamic scroll element 160 and the end plate 154 determining scroll element 150.Usually, in the recess 158 determining scroll element 150, black box S is provided with.That is, black box S is arranged on dividing plate 116 and determines between scroll element 150.Recess 158 is formed in via one the through hole (being also referred to as middle pressure passageway) determined in vortex end plate 154 and is communicated with a compression chamber fluid in a series of compression chamber C1, C2, C3.Preferably, recess 158 is communicated with middle compression chamber C2 fluid via above-mentioned through hole.Thus black box S coordinates and is formed as the back pressure cavity BC that dynamic scroll element 150 provides back pressure together with recess 158.The axial displacement of black box S is subject to the restriction of dividing plate 116.Because the side of dynamic scroll element 160 is supported by the supporting portion of main bearing seat 140, so utilize the pressure in back pressure cavity BC effectively can will determine scroll element 150 and dynamic scroll element 160 forces together.When the pressure in each compression chamber exceedes setting value, the pressure in these compression chambers produces will exceed the downforce provided in back pressure cavity BC with joint efforts thus make to determine scroll element 150 moves upward.Now, fluid in compression chamber by the clearance leakage between the top of the helical blade 166 of the gap between the top of helical blade 156 by determining scroll element 150 and the end plate 164 of dynamic scroll element 160 and dynamic scroll element 160 and the end plate 154 determining scroll element 150 to low voltage side to realize unloading, thus provide axial elasticity for scroll compressor.
On the other hand, also radial seal is needed between the side surface determining the side surface of the helical blade 156 of scroll element 150 and the helical blade 166 of dynamic scroll element 160.Therebetween the driving force that this radial seal provides by means of the centrifugal force of dynamic scroll element 160 in operation process and live axle 130 usually realizes.Particularly, in operation process, by the driving of motor 120, dynamic scroll element 160 will relative to determining scroll element 150 translation rotation, thus dynamic scroll element 160 will produce centrifugal force.On the other hand, the eccentric crank pin 132 of live axle 130 also can produce the driving force component contributing to realizing determining scroll element and dynamic scroll element radial seal in rotary course.The helical blade 166 of dynamic scroll element 160 is determined abutting in by means of above-mentioned centrifugal force and driving force component on the helical blade 156 of scroll element 150, thus realizes radial seal therebetween.When incompressible material (such as solid impurity, lubricant oil and liquid refrigerant) enter in compression chamber be stuck between helical blade 156 and helical blade 166 time, helical blade 156 and helical blade 166 can temporarily radially be separated from each other to allow foreign matter to pass through, and therefore prevent helical blade 156 or 166 to damage.This ability that can radial separate is that scroll compressor provides radial compliance, improves the reliability of compressor.
Structure and the function of black box S will be described in more detail below.As shown in Figure 2, black box S can comprise upper plate S1, lower plate S2 and the first Sealing S3 of being arranged between upper plate S1 and lower plate S2 and the second Sealing S4.The shape of black box S is substantially corresponding with the shape of recess 158, thus the first Sealing S3 can realize sealing against the radially inner side wall of recess 158, and the second Sealing S4 can realize sealing against the radial outside wall of recess 158.In addition, upper plate S1 upper end S11 can against the collar 117 be engaged on dividing plate 116 or can against the lower surface of dividing plate 116 with realize sealing.In other embodiments, the upper end S11 of upper plate S1 also can directly against dividing plate 116 sealed department and realize sealing.More specifically, but the first Sealing S3 is configured to anti-fluid to flow to back pressure cavity BC from high pressure side allow fluid to flow to high pressure side from back pressure cavity BC.Such as, the first Sealing S3 can comprise the body S32 of roughly ring-type and determine vortex end plate dorsad from body S32 and extend and the sealing lip S34 of radially inner side wall against recess 158.Body S32 is interposed between upper plate S1 and lower plate S2.Similarly, the second Sealing S4 is configured to anti-fluid to flow to low voltage side from back pressure cavity BC.Such as, the second Sealing S4 can comprise the body S42 of roughly ring-type and extend and the sealing lip S44 of radial outside wall against recess 158 towards determining vortex end plate from body S42.Body S42 is interposed between upper plate S1 and lower plate S2.
Black box S achieves the sealing as under type within the compressor: 1) upper plate S1 upper end S11 against the collar 117 on dividing plate 116 or against the lower surface of dividing plate 116 to realize separating of high pressure side and low voltage side; 2) the first Sealing S3 against the radially inner side wall of recess 158 to realize separating of high pressure side and back pressure cavity BC; 3) the second Sealing S4 against the radial outside wall of recess 158 to realize separating of back pressure cavity BC and low voltage side.
In addition, also additional Sealing can be comprised between upper plate S1 and lower plate S2, such as the 3rd Sealing and the 4th Sealing, to realize the sealing between high pressure side, low voltage side and back pressure cavity BC better, thus realize the stable and reliably running of compressor under various operating conditions.
As in background technique with reference to as described in Fig. 3, when the upper plate S1 of the black box S of prior art contacts with the collar 117, due to the distortion of all parts, be formed as small face between the bottom surface of the collar 117 and the upper end of upper plate S1 to contact or even linear contact lay, this makes the contact length between the upper end of the bottom surface of the collar 117 and upper plate S1 and area of contact (i.e. sealing area) all significantly reduce, and therefore significantly reduces the sealing effect between the collar and upper plate.
Black box S and the upper plate SP1 thereof of mode of execution of the present utility model are described referring now to Fig. 4 to Fig. 8.
Fig. 4 shows the partial sectional view of the scroll compressor of the black box S comprising mode of execution of the present utility model, Fig. 5 to Fig. 7 shows the three-dimensional view of the upper plate of the black box in Fig. 4, plan view and sectional view, the partial enlarged view that the upper plate that Fig. 8 shows the black box in Fig. 4 coordinates with the collar.
The difference of the black box S in black box S and the Fig. 2 in present embodiment is that the upper plate S1 in upper plate SP1 and Fig. 2 is structurally different, therefore, for with black box S-phase in Fig. 2 with lower plate S2, Sealing S3 and S4 by no longer repeated description, the upper plate SP1 of black box S in description present embodiment will be stressed below.
The upper end SP11 of upper plate SP1 with reference to Fig. 4, black box S can be configured to against dividing plate 116 sealed department or against the collar 117 be engaged on dividing plate 116 or against the lower surface of dividing plate 116 to realize sealing.In the present embodiment, the upper end SP11 of upper plate SP1 is radially inwardly formed with cantilever structure S12, and this configuration makes the rigidity of cantilever structure S12 be starkly lower than the rigidity of upper plate SP1 remaining part.Preferably, cantilever structure S12 and upper end SP11 is one.When the collar 117 interference fit is to dividing plate 116, the polycrystalline substance of the collar 117 is upturned, bottom surface 118 is made to become inclined-plane configuration relative to substantially horizontal, because the rigidity of cantilever structure S12 is lower than the rigidity of upper plate SP1 remaining part, thus cantilever structure S12 is easier to distortion with the true form complying with the collar 117 compared to the remaining part of upper plate SP1, thus cantilever structure S12 deforms when the collar 117 contacts with upper plate SP1, and this distortion is tending towards consistent with the distortion of the polycrystalline substance of the collar 117, thus make the bottom surface 118 of the collar 117 increase with the contact length of the upper end SP11 of upper plate SP1 and clearance C as shown in Figure 3 therebetween is significantly reduced (being even tending towards there is not any gap), this makes the bottom surface of the collar 117 and the upper end SP11 of upper plate SP1 can carry out face completely to contact, thus the sealing effect drastically increased between the collar 117 and upper plate SP1, as shown in Figure 8.
This cantilever structure S12 can be formed by the groove G between the top inner circumference edge S14 of upper end SP11 and the bottom inner circumference edge S16 of upper end SP11.This groove G can be excised a part of material of upper end SP11 by radially outward between the top inner circumference edge S14 and the bottom inner circumference edge S16 of upper end SP11 of upper end SP11 and be formed, namely, a part of material of upper end SP11 is excised from the inner circumferential radially outward of upper end SP11, as shown in Figures 5 to 7 between the top inner circumference edge S12 and the bottom inner circumference edge S16 of upper end SP11 of upper end SP11.But the upper plate SP1 with fluted G also can be that Integral mold is made.
Groove G has rounding in its corner, as shown in Figures 7 and 8, groove G is such as rectangular recess or arc groove, thus it is concentrated to make the part of transition between cantilever structure G and upper plate SP1 remaining part can not produce stress when being subject to pressing, thus avoid recurring structure fatigue when cantilever structure G is subject to the lower surface pressing of the polycrystalline substance (that is, bottom surface 118) of the collar 117 or dividing plate 116, even rupture.
The thickness D of cantilever structure S12 on the axial direction of scroll compressor in the scope of 0.5cm to 2cm, preferably in the scope of 1cm to 1.5cm, as shown in Figure 8.Compare the upper plate not being provided with cantilever structure, this configuration of cantilever structure S12 can make the clearance C between the bottom surface 118 of the collar 117 and the upper end S11 of upper plate SP1 (as shown in Figure 3) significantly reduce several times, even clearance C be disappeared.Such as, when upper plate is not provided with cantilever structure, the clearance C more than 6 μm may be there is between the bottom surface of the collar 117 and the upper end of upper plate SP1, but when upper plate is provided with cantilever structure S12 and the thickness D of cantilever structure S12 is 1cm, above-mentioned clearance C can be decreased to lower than 2 μm.
In addition, this cantilever structure S12 also can be formed as the circumferential protuberance that extends radially inwardly from upper end SP11.In this case, without the need to carrying out cutting operation to the upper end SP11 of upper plate SP1, thus can effectively enhance productivity and save cost.
Cantilever structure S12 jib-length L1 in radial directions can be upper end SP11 in radial directions total length L 2 30% to 70%, as shown in Figure 8, thus cantilever structure S12 can not be made long while reducing (cantilever structure S12 part) while the rigidity section of the upper end SP11 of upper plate SP1 can be made and cause rupturing when pressurized.
But, the thickness D of cantilever structure S12 on the axial direction of scroll compressor and length L1 is in radial directions not limited to the concrete above-mentioned numerical value limited, and contacts as long as the configuration of cantilever structure S12 can either make the upper end SP11 of upper plate SP1 or the lower surface of dividing plate 116 and the bottom surface of the collar 117 carry out face completely and cantilever structure S12 can be made can not to occur to rupture or breakage under the effect of the lower surface of the collar 117 or dividing plate 116.
Although described various mode of execution of the present utility model in detail at this, but should be appreciated that the utility model is not limited to the embodiment described in detail and illustrate here, other modification and variant can be realized when not departing from essence of the present utility model and scope by those skilled in the art.All these modification and variant all fall in scope of the present utility model.And all components described here can be replaced by component equivalent in other technologies.
