Abstract
The utility model relates to a symmetric rotary compressor which is mainly composed of a spring (1), a sliding vane (2), a cylinder (3), a polygonal piston (4), a key (5), and a shaft (6). The compressor adopts a polygonal piston, a single cylinder is divided into a plurality of independent air chambers which are symmetrically distributed, and the sum of the volume of the air chambers equals to the volume of the single cylinder. When the compressor is just matched with a sliding vane and an air inlet and outlet mechanism and is operated, air is exhausted in sequence by each air chamber, a compressive load is effectively dispersed, and the vibration and the noise is reduced. When the utility model is matched with two sliding vanes and two air inlet and outlet mechanisms, the displacement can be enlarged to twice of the displacement of the single cylinder machine when the vibration is damped, and in a similar way, the displacement can be enlarged to several times of the displacement of the single cylinder machine.
Description
The utility model relates to daily technical field of living goods, specifically, is a kind of new type compressor that is used on room air conditioner and the refrigerator refrigerator.
At present, both at home and abroad the compressor that is adopted on the room air conditioner is essentially single cylinder rolling rotor-type rotary compressor (hereinafter to be referred as rotary compressor), when the power of this compression rock increases to 3 when above, it vibrates increase, can not satisfy the requirement of room air conditioner.In order to solve this contradiction, take on this compressor, to dispose twin-tub abroad and disperse compressive load, reach the purpose that reduces to vibrate.
Twin-tub rotation-type compressor requires two off-centre on the axle to be 180 ° of balanced configurations, put rolling rotor after, the compression that can make gas is carried out with 180 ° phase difference, has disperseed compressive load effectively.But owing to will process two off-centre that become 180 ° of symmetrical distributions on the axle, cylinder body also needs two, thereby has increased the volume and the cost of complete machine, has improved machining accuracy and difficulty.
The purpose of this utility model provides a kind of symmetric type rotary compressor, and it can be improved on the basis of single cylinder, reaches effective dispersion compressive load, reduces the purpose of vibration.
The purpose of this utility model is achieved in that changes the rolling on the former single cylinder rotary compressor axle in partly replacing with a polygonal piston, the polygonal piston is separated into several independent air chambers of symmetrical distribution with cylinder, and the summation of each independent steam chest volume equals the volume of single cylinder.When axle drove the polygonal piston rotation, the inlet and outlet successively of each air chamber had disperseed compressive load effectively, reduced vibration.
The advantage of the utility model symmetric type rotary compressor is:
One, complete machine has only a cylinder, and when slide plate of this compressor configuration and inlet and outlet mechanism, the exhaust successively of each air chamber has disperseed compressive load effectively during work, has alleviated vibration.
If two are being separated in the cylinder of a plurality of independent air chambers, dispose two slide plates and inlet and outlet mechanism, can be when alleviating vibration, make air displacement increase to two times of single cylinder engine, in like manner air displacement can be improved several times.
Three, adopt the structure of polygonal piston and axle separate machined, the method for available powder metallurgy is processed the polygonal piston, has reduced difficulty of processing and cost of production.
The contrast accompanying drawing elaborates to embodiment:
Fig. 1 is two slide plate symmetric type rotary compressor structural representations.
Shown in figure (1), cylinder (3) is installed two springs (1) and two slide plates (2), polygonal piston (4) is enclosed within on the axle (6), install key (5), the axle (6) that will package piston (4) then inserts cylinder (3), and slide plate (2) and piston (4) are worked good, at last, install the end cap at cylinder two ends.
When axle rotates, the respectively simultaneously inlet and outlet of two independent air chambers, the air displacement during 360 ° of axle revolutions is that the single cylinder rotary compressor changes 360 ° of two times of making air displacement, thereby has formed a kind of novel symmetric type rotary compressor.
Claims (1)
1. symmetric type rotary compressor is characterized in that:
Be furnished with the polygonal piston on the axle, the polygonal piston is separated into a plurality of independent air chambers with single cylinder, has configurable one or more slide plates and inlet and outlet mechanism in the cylinder of a plurality of independent air chambers.
