The invention provides a compressor 100, and the compressor 100 is a rotary compressor and can be a single-cylinder single-row compressor, a single-cylinder double-row compressor, a double-cylinder compressor and the like.

In the embodiment of the present invention, as shown in fig. 1 and 2, the compressor 100 includes a compression body 10 and a liquid storage tank 20, wherein the compression body 10 is extended in a vertical direction; the liquid storage tank 20 is connected with one end of the compression main body 10 in the vertical direction; the outer diameter of the radial section of the reservoir 20 is greater than the outer diameter of the radial section of the compression body 10.

It can be understood that the liquid tank 20 of the conventional compressor 100 is disposed at the side of the compression body 10, resulting in a large radial space occupied by the compressor 100 and a large vibration and noise generated when in use. Specifically, the liquid reservoir 20 is installed vertically above or vertically below the compression body 10, i.e., the liquid reservoir 20 is disposed on the compression body 10 in the axial direction of the compression body 10, reducing the radial size of the compressor 100, and making the center of the liquid reservoir 20 and the center of the compression body 10 on the same axis, to reduce vibration and noise generated from the liquid reservoir 20 during use of the compressor 100.

The outer contour of the radial section of the reservoir 20 is circular, the outer contour of the radial section of the compression body 10 is circular, and the volume of the reservoir 20 is the product of the area of the radial section and the height thereof. It can be understood that the liquid storage tank 20 needs to ensure a certain volume to ensure a sufficient liquid storage amount, and if the height of the liquid storage tank 20 is only reduced, the volume of the liquid storage tank 20 is reduced, which is likely to cause a liquid return phenomenon, and further causes a reduction in reliability of the compressor 100.

According to the technical scheme of the invention, the liquid storage tank 20 and the compression main body 10 are axially arranged, and the purpose of reducing the height of the liquid storage tank 20 is achieved under the condition that the volume of the liquid storage tank 20 is not changed by increasing the outer diameter of the radial section of the liquid storage tank 20, so that the axial size of the compressor 100 is reduced, and the axial space occupied by the compressor 100 is further reduced.

Further, as shown in fig. 1 and 2, the ratio between the outer diameter of the radial section of the reservoir 20 and the outer diameter of the radial section of the compression body 10 is not less than 1.05 and not more than 1.5. Specifically, the outer diameter of the radial section of the reservoir 20 is D, the outer diameter of the radial section of the compression body 10 is D, and the ratio of the outer diameter of the radial section of the reservoir 20 to the outer diameter of the radial section of the compression body 10 is D/D. If the D/D is less than 1.05, the height of the liquid storage tank 20 is not reduced enough under the condition that the volume of the liquid storage tank 20 is not changed, the axial size of the compressor 100 cannot be effectively reduced, and a larger axial space is still occupied. If the D/D is greater than 1.5, the radial dimension of the reservoir 20 is excessively increased without changing the volume of the reservoir 20, which results in an excessively large overall radial dimension of the compressor 100 and an excessive amount of radial space. Therefore, to ensure that the axial space occupied by the compressor 100 is effectively reduced without occupying an excessive amount of radial space, the ratio D/D between the outer diameter of the radial section of the reservoir 20 and the outer diameter of the radial section of the compression body 10 is suitably set to 1.05 to 1.5. Such as but not limited to 1.1, 1.2, 1.3, or 1.4, etc.

In one embodiment, as shown in FIGS. 1 and 2, an insulation structure is provided between the compression body 10 and the reservoir 20. Specifically, the compression body 10 and the accumulator 20 are axially arranged, and the refrigerant in the accumulator 20 is easily heated, resulting in a decrease in performance of the compressor 100. Therefore, in the present embodiment, the heat insulation structure is disposed on the heat transfer path between the compression main body 10 and the liquid storage tank 20 to block the heat transfer between the compression main body 10 and the liquid storage tank 20, so as to prevent the refrigerant in the liquid storage tank 20 from being heated, thereby ensuring the performance of the compressor 100.

In one embodiment, as shown in fig. 1 and 2, the compression body 10 includes a first housing 11 and a first partition 12, an end of the first housing 11 is open, the first partition 12 is covered on the opening of the first housing 11, the tank 20 includes a second housing 21 and a second partition 22, an end of the second housing 21 is open, the second partition 22 is covered on the opening of the second housing 21, the second partition 22 is connected to the first partition 12, an insulation chamber 30 is formed between the first partition 12 and the second partition 22, and the insulation chamber 30 is of the insulation structure.

Specifically, the first housing 11 includes an upper cover 111 and a first cylinder 112, two ends of the first cylinder 112 in the vertical direction are respectively provided with an opening, the upper cover 111 is mounted on the opening at the upper end of the first cylinder 112, the first partition 12 is mounted on the opening at the lower end of the first cylinder 112, and the upper cover 111, the first cylinder 112 and the first partition 12 enclose to form the main body cavity 13. The second housing 21 includes a lower cover 212 and a second cylinder 211, the two ends of the second cylinder 211 along the vertical direction are respectively provided with an opening, the lower cover 212 is installed at the opening at the lower end of the second cylinder 211, the second separator 22 is installed at the opening at the upper end of the second cylinder 211, and the second separator 22, the second cylinder 211 and the lower cover 212 enclose to form the liquid storage cavity 23. The insulating chamber 30 serves to block heat transfer between the compression body 10 and the fluid reservoir 20. Alternatively, the first separator 12 may be provided in an arc plate shape or a flat plate shape; the second separator 22 may be provided in an arc plate shape or a flat plate shape, which is not limited to the above.

In one embodiment, as shown in FIG. 2, an air or vacuum arrangement is provided within the insulated chamber 30. Specifically, the periphery of the second partition 22 is protruded toward the compression body 10 to form a support protrusion ring, the support protrusion ring is connected to the first partition 12, and the first partition 12, the support protrusion ring, and the second partition 22 enclose to form the thermal insulation chamber 30. Air or vacuum has good heat insulation effect, so that the air or vacuum is arranged in the heat insulation cavity 30, and heat transfer between the liquid storage cavity 23 and the main body cavity 13 can be effectively blocked.

In another embodiment, as shown in FIG. 2, the insulated chamber 30 is in communication with the outside air. Specifically, the periphery of the second separator 22 is protruded toward the compression body 10 to form a plurality of support legs, the support legs are connected to the first separator 12, the support legs are spaced apart from each other, and a channel for communicating the heat insulation chamber 30 with the external air is formed between adjacent support legs. The heat transfer between the liquid storage tank 20 and the compression main body 10 is mainly through contact transfer, the liquid storage tank 20 is connected with the compression main body 10 through a plurality of supporting legs, the contact area between the liquid storage tank 20 and the compression main body 10 can be reduced, air is arranged between the liquid storage tank 20 and the compression main body 10, the air has a good heat insulation effect, and therefore the heat transfer between the liquid storage cavity 23 and the main body cavity 13 is effectively blocked.

In one embodiment, as shown in FIGS. 1 and 2, the reservoir 20 is located at one end of the compression body 10 vertically below. Specifically, the outer diameter of the radial section of the reservoir 20 is greater than the outer diameter of the radial section of the compression body 10, that is, the contact area between the reservoir 20 and the plane is greater than the contact area between the compression body 10 and the plane, so that the reservoir 20 obtains a better supporting effect than the compression body 10, and therefore, the reservoir 20 is disposed vertically below the compression body 10, so that the compressor 100 can be more stable, and vibration generated during operation of the compressor 100 can be reduced.

In one embodiment, as shown in FIG. 2, the first divider 12 is raised toward the reservoir 20 at a central portion thereof. Specifically, the compressor 100 further includes a compressing assembly 40, the compressing assembly 40 is disposed in the body cavity 13, and the oil reservoir 14 is disposed at the bottom of the body cavity 13 to provide lubricating oil to the compressing assembly 40. In the present embodiment, the reservoir tank 20 is disposed vertically below the first partitioning member 12, and the middle portion of the first partitioning member 12 is protruded vertically downward to increase the capacity of the oil reservoir 14, thereby storing more lubricating oil. It will be appreciated that the middle portion of the second partition 22 is recessed vertically downward to be spaced apart from the middle portion of the first partition 12, thereby preventing the middle portion of the first partition 12 from contacting the middle portion of the second partition 22, resulting in the heat of the compression body 10 being transferred to the tank 20 through the middle portions of the first and second partitions 12 and 22

In one embodiment, as shown in fig. 2, the liquid storage tank 20 has a liquid storage chamber 23, the compressor 100 further includes a compressing assembly 40 and a gas suction pipe 50, the compressing assembly 40 is disposed in the compressing body 10, and the compressing assembly 40 has a compressing chamber 421; one end of the air suction pipe 50 is connected to the compressing assembly 40, and the other end of the air suction pipe extends into the liquid storage cavity 23 to communicate the liquid storage cavity 23 and the compressing cavity 421.

Specifically, the compression assembly 40 comprises a pump body assembly 42 and a motor assembly 41, the pump body assembly 42 is provided with a compression cavity 421, and the motor assembly 41 is in driving connection with the pump body assembly 42; one end of the air suction pipe 50 is inserted into the pump body assembly 42 and is communicated with the compression cavity 421, and the other end of the air suction pipe 50 sequentially passes through the first partition 12 and the second partition 22 and extends into the liquid storage cavity 23; the upper cover 111 is provided with an exhaust pipe 70 communicating with the main body chamber 13, and the second cylinder 211 is provided with a suction pipe 80 communicating with the reservoir chamber 23. When the compressor 100 operates, a low-temperature and low-pressure refrigerant enters the liquid storage cavity 23 from the suction pipe 80, a liquid refrigerant is stored in the liquid storage cavity 23, a gaseous refrigerant enters the compression cavity 421 through the suction pipe 50 and is compressed into a high-temperature and high-pressure refrigerant in the compression cavity 421, and the refrigerant is discharged from the compression cavity 421 into the main body cavity 13 and is discharged from the compression main body 10 through the discharge pipe 70.

In an embodiment, as shown in fig. 2 and 3, the compressor 100 further includes an oil return pipe 60, one end of the oil return pipe 60 extends into the air suction pipe 50, and the other end of the oil return pipe is connected to the bottom of the reservoir 23, and an oil return hole 61 is formed in a portion of the oil return pipe 60 located in the reservoir 23.

It can be understood that the lubricating oil is used for lubricating the pump assembly 42, but when the compressor 100 operates, a small amount of lubricating oil is discharged from the discharge pipe 70 along with the refrigerant and flows in the cooling system along with the refrigerant, and enters the liquid storage cavity 23 along with the refrigerant from the suction pipe 80, and because the lubricating oil is stored at the bottom of the liquid storage cavity 23 and cannot directly enter the compression cavity 421 through the suction pipe 50, the lubricating oil in the oil storage tank 14 is less and less, and the reliability of the compressor 100 is affected. Specifically, one end of the oil return pipe 60 is inserted into the lower cover 212 and fixed, and the other end of the oil return pipe extends into the air suction pipe 50, when the air suction pipe 50 sucks air, the flow velocity in the air suction pipe 50 increases, according to bernoulli's principle, negative pressure is generated at the pipe orifice at the other end of the oil return pipe 60, so as to generate pressure difference between the pipe orifice at the other end of the oil return pipe 60 and the oil return hole 61, and therefore, the lubricating oil is sucked into the oil return pipe 60 through the oil return hole 61, and is discharged into the air suction pipe 50 through the pipe orifice at the other end of the oil return pipe 60, and then enters the compression chamber 421, and finally returns to the oil storage tank 14.

Further, as shown in fig. 3, the oil return hole 61 is disposed near the bottom of the reservoir chamber 23. Specifically, the lubricant oil is accumulated in the bottom of the reservoir chamber 23, and the oil return hole 61 is provided near the lower cover 212 so as to recover the lubricant oil.

The present invention further provides a refrigeration apparatus, which includes a compressor 100, and the specific structure of the compressor 100 refers to the above embodiments, and since the refrigeration apparatus adopts all technical solutions of all the above embodiments, the refrigeration apparatus at least has all beneficial effects brought by the technical solutions of the above embodiments, and details are not repeated herein. The refrigeration equipment can be an air conditioner, a refrigerator, a heat pump water heater and the like.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
