A compressor 200 according to an embodiment of the present invention is described below with reference to fig. 1 to 11. It should be noted that the compressor 200 may be a rotary compressor, a horizontal-bar rolling rotor compressor, or a double-cylinder rolling rotor compressor.
As shown in fig. 1 to 11, a compressor 200 according to an embodiment of the present invention includes a compressor body 210 and an accumulator 100.
Specifically, as shown in fig. 1 and 7, the compressor body 210 has a suction port 211, and the suction port 211 communicates with the inside of the compressor body 210. As shown in fig. 1 and 7, the height H of the reservoir 1002Height H from the compressor body 2101Equal, i.e. H1＝H2. It will be appreciated that the tall reservoir, with the same volume of reservoir 100, has a small diameter. That is, by disposing the first segment 131 of the second suction pipe 130 on the circumferential wall 112 of the suction cup 110 and then setting the height of the accumulator 100 to be equal to the height of the compressor body 210, the height of the accumulator can be increased and the radial size of the accumulator 100 can be reduced, so that the radius of gyration R of the compressor 200 can be reduced and the vibration of the compressor 200 can be reduced.
As shown in fig. 3, 5, and 11, the reservoir 100 may include a suction cup 110, a first suction tube 120, and a second suction tube 130. Wherein, the first suction pipe 120 is disposed on the top wall 111 of the suction cup 110, and the first suction pipe 120 is communicated with the suction cup 110.
As shown in fig. 3, 5 and 11, the second suction pipe 130 may include a first section 131 and a second section 132, the second section 132 is located in the suction cup 110 and is communicated with the suction cup 110, the first section 131 is inserted through the peripheral wall 112 of the suction cup 110, one end of the first section 131 is located outside the suction cup 110 and is communicated with the first section 131 and the suction port 211, the other end of the first section 131 is located in the suction cup 110 and is connected with one end of the second section 132, and the first section 131 is communicated with the second section 132.
According to the compressor 200 of the embodiment of the present invention, the first segment 131 of the second suction pipe 130 is disposed on the peripheral wall 112 of the suction cup 110, and the height of the accumulator 100 is set to be equal to the height of the compressor body 210, so that the overall height of the compressor 200 can be reduced, the height of the accumulator 100 can be increased, the distance between the suction port 211 of the compressor 200 and the first suction pipe 120 can be reduced, the radius R of gyration of the compressor 200 can be reduced, and the vibration of the compressor 200 can be reduced.
As shown in fig. 5, according to some embodiments of the present invention, the second suction pipe 130 may further include a connection section 133, one end of the connection section 133 is connected to the other end of the first section 131, the other end of the connection section 133 is connected to one end of the second section 132, the connection section 133 has a circular shape having an opening or the connection section 133 has a U-shape.
It should be noted that, by providing the connection section 133, the flow path of the refrigerant in the second suction pipe 130 may be extended, so that secondary gas-liquid separation may be achieved by using the second suction pipe 130, that is, when the fluid flows in the second suction pipe 130, the lubricant and the liquid refrigerant may adhere to the pipe wall of the second suction pipe 130 and slide down along the inner wall of the second suction pipe 130, or the lubricant and the liquid refrigerant may directly fall into the connection section 133, so that the possibility that the lubricant and the liquid refrigerant enter the compressor body 210 may be reduced, and the probability of liquid slugging of the compressor 200 may be reduced.
Further, as shown in fig. 5 and 6, the connecting section 133 has an oil return hole 134. It should be noted that the lubricant oil and the liquid refrigerant separated by the second suction pipe 130 may return to the interior of the suction cup 110 through the oil return hole 134, so that the lubricant oil and the liquid refrigerant may be prevented from entering the interior of the compressor body 210. Further, as shown in fig. 6, in order to allow more lubricant and liquid refrigerant to flow back into the suction cup 110 according to the downward flow characteristic of the liquid under the action of gravity, the oil return hole 134 may be located at the lowest point of the connection segment 133. Further, in order to return the lubricant oil and the refrigerant in the liquid state to the inside of the suction cup 110 more smoothly, the oil return hole 134 may be plural.
As shown in FIG. 3, according to some embodiments of the present invention, second suction conduit 130 may be L-shaped with a smooth transition between first section 131 and second section 132. It should be noted that the L-shaped second suction pipe 130 may include two straight segments extending along a straight line, wherein one straight segment may be configured as a first segment 131, another straight segment may be configured as a second segment 132, and the first segment 131 and the second segment 132 may be connected and communicated through a smooth transition.
Therefore, on one hand, the structure of the second suction pipe 130 can be simplified, the processing technology of the second suction pipe 130 can be simplified, on the other hand, the structural strength of the second suction pipe 130 can be improved by smooth transition, and stress concentration at the turning structure of the second suction pipe 130 is avoided, so that the second suction pipe 130 is prevented from fatigue damage.
As shown in fig. 3, 5, and 11, in some embodiments, the other end of the second segment 132 is higher than the one end of the first segment 131. For example, in the example shown in fig. 3, the upper end of the second segment 132 is located above the left end of the first segment 131. The gas-liquid mixed refrigerant enters the suction cup 110 through the first suction pipe 120 and is subjected to gas-liquid separation inside the suction cup 110, the liquid refrigerant flows to the bottom of the suction cup 110 under the action of gravity, the gaseous refrigerant enters the second suction pipe 130 from the other end of the second section 132 (i.e., the upper end of the second section 132), and the gaseous refrigerant flows to the first section 131 and the suction port 211 under the guidance of the second suction pipe 130 and enters the compressor body 210 from the suction port 211. The upper end of the second section 132 is higher than the left end of the first section 131, which is beneficial to improving the separation efficiency of gas-liquid separation and reducing the possibility that the liquid refrigerant enters the second suction pipe 130.
As shown in fig. 3 and 4, in some embodiments, the first segment 131 may have an oil return hole 134. Therefore, the lubricant oil and the liquid refrigerant separated by the second suction pipe 130 can return to the interior of the suction cup 110 through the oil return hole 134, so that the lubricant oil and the liquid refrigerant can be prevented from entering the interior of the compressor body 210. It should be noted that the oil return hole 134 may be provided at a portion of the first segment 131 located inside the suction cup 110, and specifically, it may be located on the peripheral wall 112 of the first segment 131 facing the bottom of the suction cup 110, as shown in fig. 4.
According to some embodiments of the present invention, the second section 132 extends in an up-down direction (i.e., a vertical direction), and the first section 131 extends in a horizontal direction (a direction parallel to a left-right direction as shown in fig. 3). It should be noted that, the height of the upper end of the second section 132 is conveniently increased by extending the second section 132 in the vertical direction, so that the height of the upper end of the second section 132 is favorably increased and is located above the first section 131, thereby preventing the liquid refrigerant from entering the second suction pipe 130, and further, by arranging the first section 131 in a structure extending in the horizontal direction, the liquid refrigerant can smoothly flow into the suction port 211, thereby improving the smoothness of the refrigerant flow.
In some embodiments, as shown in fig. 3, 5 and 11, the compressor 200 may further include a filter screen 140, the filter screen 140 being located within the suction cup 110, the filter screen 140 being located between the other ends of the first suction pipe 120 and the second suction pipe 130. On one hand, the fluid flowing into the suction cup 110 can be filtered, and impurities such as scrap iron can be prevented from entering the suction cup 110 or the compressor body 210. On the other hand, the flow rate of the fluid entering the suction cup 110 from the first suction pipe 120 can be reduced by the filter screen 140, so as to improve the efficiency of gas-liquid separation of the suction cup 110.
In some embodiments, as shown in fig. 7 and 8, the central axis of the compressor body 210 is a straight line L1The central axis of the inlet 211 is a straight line L2The central axis of the reservoir 100 is a straight line M, a straight line L1And a straight line L2The plane is a plane S1Straight line L1The plane where the straight line M is located is a plane S2Plane S1And plane S2At an included angle of β1Wherein, β1Is less than or equal to 45 degrees. Thereby making it possible to reduce the radius of gyration of the compressor 200.

In the example shown in fig. 9-10, the reservoirs 100 may be two in number. For convenience of description, one of the two reservoirs 100 is a first reservoir 100a, and the other is a second reservoir 100 b. The central axis of the first reservoir 100a is a straight line N1The central axis of the second reservoir 100b is a straight line N2. The central axis of the compressor body 210 is a straight line L1。
As shown in FIG. 10, the central axis of the inlet 211 is a straight line L2Straight line L1And a straight line L2Therein is arrangedThe plane is a plane S1Straight line L1And a straight line N1The plane is a plane T1Straight line L2And a straight line N2The plane is a plane T2.

To equalize the pressure between two reservoirs 100, in some embodiments, a pressure equalization tube 150 may be disposed between adjacent two reservoirs 100. It should be noted that the pressure equalizing pipe 150 is a pipe for communicating the interiors of the two reservoirs 100, so that the internal pressures of the two reservoirs 100 are the same. In some embodiments, there are at least two reservoirs 100 in the plurality of reservoirs 100, the two reservoirs 100 having the same volume.
