Namely, in the embodiment of the invention, the arc-shaped liquid distributor is arranged on the peripheral wall of the compressor, so that the distance between the center of gravity and the center of the compressor is smaller than that in the prior art.

According to the embodiment of the invention, the knockout is arranged to be installed on the peripheral wall of the compressor body 1 in an arc shape, so that the center of gravity of the compressor is closer to the center of the compressor, and the compressor is more stable in operation, so that the vibration of the compressor and the noise generated by the unbalanced force are reduced.

As shown in fig. 2 to 4, the dispenser 2 has a first end 21 and a second end 22 at both ends in the circumferential direction of the body 1;

wherein the top side of the first end portion 21 is provided with an air inlet, the air inlet is provided with a dispenser air inlet pipe 211, the bottom side of the second end portion 22 is provided with an air outlet, the air outlet is provided with a dispenser air outlet pipe 221, and the refrigerant enters the dispenser 2 through the dispenser air inlet pipe 211 at the top side of the first end portion 21 for gas-liquid separation and then is discharged from the dispenser air outlet pipe 221 at the bottom side of the second end portion 22. Since the air inlet pipe 211 and the air outlet pipe 221 are respectively arranged at two ends of the dispenser 2, the flow path of the air-liquid mixture in the dispenser 2 can be increased, so that the liquid-separating effect of the dispenser 2 is improved, and the problem that the reliability of the compressor is affected due to the liquid-separating is avoided.

the top side of the dispenser 2 is provided with a plurality of dispenser air inlet pipes 211, and the plurality of dispenser air inlet pipes 211 are uniformly distributed on an arc-shaped path from the first end 21 of the dispenser 2 to the second end 22 of the dispenser;

wherein the air outlets of the plurality of dispenser air inlets 211 are opposite to the dispenser assembly 23.

Specifically, as shown in fig. 7, the number of intake pipes 211 may be set to one, two, three, four, etc., and the specific number of intake pipes 211 is not limited in the embodiment of the present invention, and it is relatively preferable to provide two intake pipes 211 for a dispenser on the top side of the dispenser 2. In the embodiment of the invention, the number of the air inlets is increased (namely, the number of the air inlets 211 is increased) on the basis of the arc-shaped dispenser, so that the local resistance of the air inlets of the dispenser is reduced.

In any of the above embodiments, as shown in fig. 8 and 9, the inside of the dispenser 2 is provided with an air guide 24, where the air guide 24 is disposed above the liquid dispensing component 23 and is designed to be arc-shaped as a whole;

According to the embodiment of the invention, on the basis of the arc-shaped liquid separator, the arc-shaped air duct is further added in the liquid separator 2, and the air duct is uniformly distributed on the arc-shaped air duct, so that the refrigerant from the system can more uniformly enter the internal space of the liquid separator, and the gas-liquid separation is better carried out in the liquid separator, thereby enhancing the liquid separation effect of the liquid separator.

Wherein the arcuate airway 24 is mounted within the dispenser 2 in a position shown in figure 10.

M222919CNI-S

It should be noted that, the air guide 24 in the embodiment of the present invention is specifically described by taking an arc air guide pipe as an example, however, in some alternative embodiments, the air guide 24 may be other arc air guide members with air guide function, for example, the air guide may be configured as an arc air guide plate, and a plurality of air guide holes are uniformly formed on the surface of the air guide plate, so that the liquid separating effect of the liquid separator 2 is enhanced.

In any of the above embodiments, as shown in fig. 11, the above-mentioned liquid separation assembly 23 includes a filter screen 231, a filter screen holder 232, and a pressure ring 233, where the filter screen 231, the filter screen holder 232, and the pressure ring 233 are arc-shaped members; the pressing ring 233 is used for fixing the filter screen 231, the liquid separation assembly 23 is connected with the inner wall of the shell 1 of the liquid separator through the pressing ring 233, and specifically, the liquid separation assembly 23 is fixed with the shell of the liquid separator 2 through a welding mode.

In detail, as shown in fig. 11 and 12, the filter screen support 232 is provided with through holes, the through holes are uniformly arranged on the filter screen support 232, the filter screen 231 is provided with annular protrusions, and the annular protrusions of the filter screen 231 can completely cover the through holes on the filter screen support 232.

It should be noted that the above-mentioned dispenser 2 is formed by welding three parts of an upper housing, a middle housing and a lower housing, wherein the upper housing, the middle housing and the lower housing are all arc-shaped.

In any of the above embodiments, as shown in fig. 13, the bottom side of the dispenser 2 has a plurality of dispenser exhaust pipes 221;

in particular, two knockout exhaust pipes 221 in the embodiment are provided, and a phase difference exists between the two knockout exhaust pipes 221.

It should be noted that, when the number of the knockout exhaust pipes 221 is one, the above-mentioned compressor is a single-cylinder compressor, and the exhaust port of the knockout exhaust pipe 221 is communicated with the air suction port of the single-cylinder compressor.

When the two knockout exhaust pipes 221 are two, the above-mentioned compressor is a double-cylinder compressor, and two exhaust ports of the two knockout exhaust pipes 221 are respectively communicated with two cylinder air inlets of the double-cylinder compressor.

That is, the dispenser 2 having the single dispenser discharge pipe 221 is applied to a single cylinder compressor as shown in fig. 2, and the dispenser 2 having the double dispenser discharge pipe 221 is applied to a double cylinder compressor as shown in fig. 14.

In any of the above embodiments, the compressor according to the present invention is a rotor compressor.

M222919CNI-S

It should be noted that, when the dispenser with the two dispenser exhaust pipes 221 is applied to the double-cylinder compressor, because the dispenser 2 is of an arc design and a phase difference exists between the exhaust ports of the two dispenser exhaust pipes 221, the dispenser 2 under the structure can reduce the bending radius of the bent pipe connecting section of the dispenser exhaust pipe 221 (note: compared with the existing dispenser, the distance between the center of the dispenser and the main body of the compressor is closer, so that the radius of the bent pipe of the dispenser can be set smaller), thereby reducing the local stress at the bent pipe, and avoiding the bent pipe fracture caused by the local stress deflection of the bent pipe of the dispenser.

In addition, due to the arrangement of the two knockout exhaust pipes 221 and the phase difference of the exhaust ports of the two knockout exhaust pipes 221, the positions of the air inlets of the upper cylinder and the lower cylinder in the double-cylinder compressor can be changed, so that the positions of the exhaust ports of the upper cylinder and the lower cylinder and the positions of the sliding vane grooves can be changed, and the distribution condition of the flow fields in the upper cylinder and the lower cylinder can be changed. Meanwhile, the exhaust time interval of the upper cylinder and the lower cylinder can be changed by the mode, so that the distribution condition of the flow field in the compressor is changed. Therefore, under the condition of reasonable design, the flow field distribution in the compressor can be more uniform, so that the energy efficiency of the compressor is higher.

It should be noted that, the arrangement of the exhaust pipe 221 of the dual knockout and the design scheme of the positions of the exhaust ports and the slide slots of the upper and lower cylinders are static, mainly aiming at the design stage of the compressor, so that the design can be more flexible. The distributor is arc-shaped, so that the position of the air suction port of the compressor cylinder can be more flexibly arranged, the position of the air suction port of the compressor cylinder can be changed, the positions of the air suction ports of the upper cylinder and the lower cylinder are not limited by the positions of the distributor, and then certain phase difference exists between the exhaust ports of the upper cylinder and the lower cylinder.

By arranging the two exhaust ports of the two knockout exhaust pipes 221 to have a phase difference in the embodiment of the present invention, the following specific beneficial effects can be achieved when the two knockout exhaust pipes are assembled on a compressor:

on the other hand, in structural design, the two liquid separator exhaust pipes 221 have two exhaust pipes, and the phase difference between the two exhaust pipes can be changed, because the liquid separator exhaust pipes 221 are matched with the air inlets of the cylinders, the phase difference between the air inlets of the upper cylinder and the lower cylinder can be changed, and because the air inlets and the air outlets of the upper cylinder and the lower cylinder are respectively arranged at two sides of the sliding vane groove, the relative positions of the air inlets, the relative positions of the air outlets and the relative positions of the sliding vanes of the upper cylinder and the lower cylinder can be changed. Because the exhaust port phase difference can be designed according to actual conditions, the exhaust time interval of the upper cylinder and the lower cylinder can be designed and changed according to actual requirements along with the operation of the compressor, thereby changing the flow field distribution in the compressor.

Specifically, because the air inlet and the air outlet of the compressor are respectively arranged at two sides of the compressor, the temperature of the refrigerant in the compression cavity of the compressor is obviously higher than that of the air suction cavity of the compressor along with the compression of the refrigerant, and the temperature of the refrigerant is equal to that of the compression cavity of the compressor, namely M222919CNI-S

The temperature of the parts connected with the exhaust port of the compressor can be obviously increased, the temperature of the parts on the air suction side is obviously lower, the local temperature on the exhaust side of the compressor can be higher for a long time, the thermal deformation of the parts is different due to uneven distribution of a temperature field, so that the local friction of the compressor is increased, the abrasion of the parts is increased, and the reliability of the compressor is greatly influenced. And the positions of the air inlets of the upper cylinder and the lower cylinder are changed, so that certain phase difference exists at the air outlets of the cylinders of the compressor, the distribution of the temperature field is more reasonable, the problem that local deformation is serious due to the fact that the temperature of the local temperature field is higher is solved, and the performance and the reliability of the compressor are prevented from being greatly influenced.

On the other hand, by changing the position of the compressor cylinder intake, the position of the corresponding compressor exhaust port will also change, so that there is an optimum exhaust port position that minimizes the compressor exhaust pressure fluctuation. Under the condition that the crank throw phase difference is certain, the phase difference of the air inlets of the upper cylinder and the lower cylinder is changed, so that certain phase difference exists between the air outlets of the upper cylinder and the lower cylinder, at the moment, the change of the exhaust flow of the compressor along with the time is different, and the fluctuation of the exhaust flow of the compressor along with the time is smaller through changing the position of the air outlets, so that the flow field inside the compressor is more stable, the fluctuation is smaller, and the problems of unstable overall operation, larger noise and the like of the compressor caused by too large fluctuation are avoided. (remark: under a certain structure, the flow field in one space is determined by the input and output fluid, and the compressor exhaust is intermittent, and the exhaust of the upper and lower cylinders has a certain phase difference, so that the flow field distribution in the compressor can be changed by changing the phase difference of the exhaust of the upper and lower cylinders, and the flow field distribution in the compressor is more uniform).
