Abstract
The utility model relates to a novel scroll compressor which belongs to the technical field of refrigeration compressors. The scroll compressor is provided with an auxiliary air exhaust opening communicated to a compression chamber at the position where a static eddy is adjacent to the air exhaust opening; a gravity-held check valve only exhausting air to the outside of the compression chamber is arranged above the auxiliary air exhaust opening; when the compressor operates overtime, the force exerted on the gravity-held valve block comprises the downward gas force Fs of an exhaust chamber, the gravity G of a gravity-held valve block and the upward gas force Fa of a scroll compressor chamber; when the over-compression phenomenon of the compressor occurs under certain working conditions, the pressure of the compression chamber is excessively large, and Fa is larger than Fs plus G, the gravity-held valve block moves upwards to leave the auxiliary air exhaust opening to cause the compression chamber to be communicated with the exhaust chamber, refrigerant is discharged to the exhaust chamber of the scroll compressor through the auxiliary air exhaust opening, thus realizing the exhaust in advance, reducing the unnecessary compression work and the load of the motor, improving the seasonal energy efficiency ratio of the air conditioner, and realizing energy-saving and cost-reducing effects.
Description
Technical field
The utility model relates to technical field of refrigeration compressors, relates in particular to a kind of novel scroll compressor.
Background technique
Common scroll compressor mainly is made up of movable orbiting scroll, quiet whirlpool dish, bent axle, pedestal, anti-rotation mechanism and motor etc., the molded lines of dynamic and static scroll all is a spirality, movable orbiting scroll is with respect to quiet whirlpool dish off-centre and differ 180 ° of opposed installations, they axially can contact on several straight lines in theory, touch with relative vortex body bottom connection the end of vortex body molded lines, so between the sound vortex body, form a series of meniscate pressing chambers, i.e. element volume.Is rotating center and when doing the revolution translation of no rotation with certain turning radius at movable orbiting scroll with the center of quiet whirlpool dish, the outer ring crescent-shaped space just can constantly move to the center, element volume is constantly dwindled and pressure constantly raises, until communicating with the central row pore, pressurized gas are discharged compressor.
In the actual using process of air-conditioning, because the variation of season, diurnal temperature, the operating mode of air-conditioning system inside also changes, and promptly the work operating mode of compressor is in continuous variation, therefore in the scroll compressor real work, the phenomenon that can have overcompression, promptly excessive at the pressure of the later stage of compression process pressing chamber, and the overcompression meeting increases resistance to compression pression in the compressor compresses process, increase the energy consumption of motor in operation process, power consumption increases, and causes the waste of the energy, makes the compressor efficiency low.
The model utility content
The utility model is to occur the problem of overcompression in operating mode changes process at present scroll compressor, and a kind of a kind of novel scroll compressor that overcomes the above problems is provided.
For reaching above purpose, adopt following technological scheme:
A kind of novel scroll compressor, the quiet whirlpool dish middle position of described scroll compressor is provided with relief opening, the position of described quiet whirlpool dish adjacent row gas port is provided with the auxiliary exhaust port that is communicated to pressing chamber, described auxiliary exhaust port top be provided with can only exhaust outside pressing chamber the gravity one-way valve.
Wherein said gravity one-way valve includes the valve seat that is fixed on the auxiliary exhaust port top, and the bottom of valve seat above auxiliary exhaust port is provided with a valve chamber, is provided with a up and down weight valve piece in the valve chamber, and valve chamber has the vent that is communicated to outside the valve seat.
Wherein said gravity one-way valve includes the counterbore that is arranged on the auxiliary exhaust port top, is provided with a weight valve piece in the counterbore, and the counterbore top is provided with a pipe position double-screw bolt pipe.
Wherein said gravity one-way valve includes the weight valve piece that the auxiliary exhaust port top is set, and the activity of weight valve piece is located in a pair of being fixed on the guide pillar that coils in quiet whirlpool.
Wherein said auxiliary exhaust port is provided with in pairs in quiet whirlpool dish symmetrical position.
The beneficial effects of the utility model are: scroll compressor of the present utility model is provided with the auxiliary exhaust port that is communicated to pressing chamber in the position of quiet whirlpool dish adjacent row gas port, described auxiliary exhaust port top be provided with can only exhaust outside pressing chamber the gravity one-way valve; Out-of-date in compressor operating, the power that the weight valve piece is subjected to comprises the downward exhaust cavity gas force Fs and the gravity G of weight valve piece, and compression chamber gas force Fa upwards, during proper functioning, during Fa＜Fs+G, the weight valve piece moves downward is close to auxiliary exhaust port realization sealing, stops the refrigeration agent of pressing chamber to leak into exhaust cavity by auxiliary exhaust port under pressure-driven; When compressor produces the overcompression phenomenon under some work condition environment, when the pressure of pressing chamber is excessive, this moment is during Fa＞Fs+G, and the weight valve piece moves upward and leaves auxiliary exhaust port pressing chamber is communicated with exhaust cavity, and the refrigeration agent of pressing chamber is discharged to the scroll compressor exhaust cavity by auxiliary exhaust port in the compressor, realize exhaust in advance, reduce unnecessary compressed action, reduce the load of motor, reduce the consumption of energy, the seasonal energy efficiency ratio (seer) of air-conditioning increases, and plays energy-saving and cost-reducing effect.

Embodiment
Below in conjunction with accompanying drawing the utility model is further specified:
Gravity one-way valve 3 of the present utility model various informative, its main thought is to utilize the suffered self gravitation G exhaust cavity 15 inner air pressure Fs of weight valve piece 31 and the actuating pressure Fa of pressing chamber 12 to control moving up and down of weight valve piece 31, thereby reach keying to auxiliary exhaust port 13, the in advance exhaust of control pressing chamber 12 under the overcompression situation, reduce resistance to compression pression and motor 10 energy consumptions, the seasonal energy efficiency ratio (seer) of air-conditioning increases, play energy-saving and cost-reducing effect, it is simple in structure, control is sensitive, be difficult for being damaged or losing efficacy; Shown in Fig. 4,5, be another embodiment according to main thought of the present utility model, guide the stroke up and down of weight valve piece 31 by the two bolt guide pillars 7 that are fixed on quiet whirlpool dish 1, screw portion 71 screws in quiet whirlpool and coils 1 fixing bolt guide pillar 7, and guide pillar 7 top bolt heads 72 can play the effect that prevents that weight valve piece 31 from coming off.
The above embodiment, it is preferred embodiments of the present utility model, be not to limit the utility model practical range,, all should be included in the utility model patent claim so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify.
