Embodiment
Below in conjunction with specific embodiments and the drawings, the invention will be further described; set forth more details in the following description so that fully understand the present invention; but the present invention obviously can implement with multiple this alternate manner described that is different from; those skilled in the art when doing similar popularization, deduction without prejudice to when intension of the present invention according to practical situations, therefore should can not limit the scope of the invention with the content of this specific embodiment.
Fig. 1 to Fig. 4 shows embodiments of the invention 1, Fig. 5 A and Fig. 5 B and shows embodiments of the invention 2.It should be noted that these and follow-up other accompanying drawing all only exemplarily, it is not draw according to the condition of equal proportion, and should not be construed as limiting in this, as to the protection domain of actual requirement of the present invention.
Embodiment 1
The external casing parts of scroll compressor are built with driving mechanism and compressing mechanism.Housing is made up of aluminum alloy material usually, for installing and holding driving mechanism, compressing mechanism etc., and is fixed on external agency.The housing parts of common scroll compressor comprises front end housing 1, cylinder body 3, back cylinder cover 5 etc., and cylinder body 3 can coil 7 with quiet whirlpool and be separated from each other, and cylinder body and quiet whirlpool also can be simplified to coil make one, thus the outer wall of quiet whirlpool dish 7A is as cylinder body.Quiet whirlpool dish and movable orbiting scroll include end plate and volute wall portion.
Driving mechanism drives (not shown) by belt pulley, the torque axis from belt pulley is turned to the power making movable orbiting scroll 10 flexing axle 11 center line O1 make eccentric operating.Bent axle 11 is installed on front end housing 1 by main bearing 39, and crank 12 is stretched out in one end of bent axle 11, and the center line O2 of crank 12 departs from the center line O1 of bent axle 11.Be enclosed within the eccentric wheel 13 outside crank 12, have mesopore, mesopore is identical with the shape of crank 12, and for transmitting torque, mesopore and crank 13 exist micro-gap, for finely tuning the position of movable orbiting scroll 10.Bearing 14 is contained in outside eccentric wheel 13.Equilibrium block 16 is fixed on outside eccentric wheel 13, for offsetting the amount of unbalance produced in movable orbiting scroll 10 eccentric operating.
The low-pressure gas sucked from air conditioner loop is compressed into pressurized gas by compressing mechanism, mainly comprises quiet whirlpool dish 7 and movable orbiting scroll 10.Quiet whirlpool dish 7 keeps static with cylinder body 3 or makes one, and two whirlpool dishes engage each other, and outermost surface space is air aspiration cavity 17, and is surrounded as multiple dynamic active chamber 19.Movable orbiting scroll 10 flexing axle 11 center line O1 under the drive of crank 12 operates, and active chamber 19 coils outer circumferential center by whirlpool and moves, and volume reduces gradually, the gas in compression enclosed space.When active chamber 19 moves on to center, the exhaust port 31 on the dish end plate 30 of quiet whirlpool, drains into the exhaust cavity 32 at the dish 7A back side, quiet whirlpool.
Movable orbiting scroll 10 has end plate 33, and end plate 33 center has bulge loop 34, installs bearing 14 in the bulge loop 34 of end plate 33.When bent axle 11 rotates, crank 11 drives movable orbiting scroll 10 to make eccentric operating.More satisfactory state is that movable orbiting scroll 10 keeps constant relative position with crank 12, but because movable orbiting scroll 10 is by the gas pressure of direction change wherein, inevitably has the center line O2 of flexing handle 12, the trend of also i.e. movable orbiting scroll 10 center line rotation.In order to prevent the rotation of movable orbiting scroll 10, between movable orbiting scroll 10 and housing, annular arranges multipair rotation-preventing mechanism.
Between the end plate 33 and front end housing 1 of movable orbiting scroll 10, form back pressure cavity 35, an annular resilient sheet 36 is made of metal, such as spring steel, and smooth surface is wear-resisting, and thickness can be arranged to 0.1 ~ 0.8mm, is located at end plate 33 back side of movable orbiting scroll 10.The outward edge 36A of spring sheet 36 is clamped in front end housing 1 and quiet whirlpool is coiled between the outer wall of 7A, is all sealed and matched between the outer wall of spring sheet 36, front end housing 1, quiet whirlpool dish 7A.
Back pressure cavity 35 encloses formation primarily of front end housing 1, spring sheet 36, movable orbiting scroll 10, the end plate 33 of movable orbiting scroll 10 arranges axial aperture 37, the active chamber 19 of closer center line O1 is connected with back pressure cavity 35, the pressure in active chamber 19 is made to inject back pressure cavity 35, owing to being gas mixture in pressure chamber, therefore aperture also carries lubricant oil to back pressure cavity 35 simultaneously.Aperture 37 can lubricate bearing 14 within being positioned at bulge loop 34 towards the opening of back pressure cavity 35.
As shown in Figure 1 to Figure 3, sealing gasket 40 is provided with between front end housing 1 and spring sheet 36, spring sheet 36 and quiet whirlpool are coiled between 7A outer wall and are provided with sealing gasket 41, the compounded rubber steel plate that sealing gasket 41 corrodes for oil resistant refrigerant or rubber material, make all to be sealed and matched between spring sheet 36, front end housing 1, quiet whirlpool dish 7A outer wall, main purpose prevents gas from enclosure interior to external leakage.In addition, when sealing gasket 40,41 also makes spring sheet 36 in its natural state, form a slim cavity with front end housing 1 interior edge face, add back pressure area.
When compressor does not work or the end plate 33 both sides pressure balance of movable orbiting scroll 10 time, there is nature as shown in Figure 2 in spring sheet 36; During compressor operating, active chamber pressure becomes large gradually, promotes movable orbiting scroll 10 towards front end housing 1 direction, spring sheet 36 produces distortion as shown in Figure 3, the outer rim 33A of the end plate 33 of movable orbiting scroll 10 compresses spring sheet 36 simultaneously, and both produce close contact, back pressure cavity 35 and air aspiration cavity 17 is cut off; The pressurized gas of active chamber 19 enter into back pressure cavity 35 lentamente by aperture, and back pressure raises lentamente; When back pressure is equal to or greater than pressure for movable orbiting scroll end plate 33 of each active chamber 19 and air aspiration cavity 17, promote movable orbiting scroll 10 and move backward, spring sheet returns to the state of Fig. 2, and is adjacent to movable orbiting scroll end plate 33.
The effect of back pressure reduces the sliding friction between movable orbiting scroll end plate 33 and protecgulum 1, thus reduce wear and noise; Make to compress between movable orbiting scroll 10 and quiet whirlpool dish 7A simultaneously, reduce the leakage between active chamber 19, improve compression efficiency.
Previous embodiment eliminates support of the prior art, makes compressor volume less; When back pressure promotes movable orbiting scroll end plate 33, spring sheet 36 is comparatively large, not easy to wear with the compression area of contact of movable orbiting scroll end plate 33.
As shown in Figure 4, bottom exhaust cavity 32, generally contain lubricant oil, therefore can offer drainback passage, be communicated with bottom exhaust cavity 32 with back pressure cavity 35, further lubricating bearings 14 and other motion.Drainback passage be included in cylinder body 3/ quiet whirlpool dish 7A outer wall first passage 44, be opened in the hole 45 on sealing gasket 40,41 and elastic plate 36, the second channel 46 on front end housing 1.The aperture in the hole 45 on elastic plate 36 can be arranged to be less than first passage 44 and second channel 46, play reducing pressure by regulating flow effect, because the aperture 37 on movable orbiting scroll end plate 33 is main back pressure sources, and drainback passage is only for oil return, does not wish that it carries exhaust cavity gas secretly.
Sealing gasket 40,41 in the present embodiment also can use O type circle instead, but is not suitable for O and offers drainback passage.
