Description

Technical Field

[0001] The present application relates to the technical field of compressors, and particularly to a liquid receiver and a compressor. Background Art

[0002] A compressor is a fluid machine that raises low-pressure gas to high-pressure gas. Inside the housing of the compressor, there is a cylinder. During operation, low-temperature and low-pressure refrigerant gas enters the cylinder from the intake pipe. After being compressed by the cylinder, high-temperature and high-pressure refrigerant gas is discharged from the exhaust pipe, providing power for the refrigeration cycle, thereby realizing the refrigeration cycle of compression → condensation → expansion → evaporation. Since it is impossible to ensure that the refrigerant can be completely vaporized during the evaporation stage during the operation of the system, in order to prevent liquid refrigerant from the evaporator from entering the cylinder and causing liquid hammer, a liquid receiver needs to be provided between the cylinder and the evaporator.

[0003] Existing liquid receivers generally include a cylinder body, a bracket, a filter screen assembly, an intake pipe, and an exhaust pipe. The intake pipe is arranged at the upper end of the cylinder body. One end of the exhaust pipe is arranged in the cylinder body, and the other end of the exhaust pipe extends out from the bottom of the cylinder body. The bracket is arranged inside the cylinder body to fix the exhaust pipe and prevent it from deflecting. The filter screen assembly is arranged between the intake pipe and the exhaust pipe to filter garbage and prevent liquid hammer.

[0004] Among them, both the filter screen assembly and the bracket are relatively single in function. Therefore, they need to be manufactured and installed separately, resulting in a relatively high manufacturing cost of the existing liquid receiver. Summary of the Invention

[0034]

Embodiment 1

[0035] Please refer to Figures 1 to 3 , which is a schematic structural diagram of the liquid storage device of the first embodiment of the present invention. As Figures 1 to 3 shown, the liquid storage device 10 includes: a cylinder body 1, an intake pipe 2, an exhaust pipe 3, and a reinforcing plate 4; the cylinder body 1 has an inner cavity, the intake pipe 2 is inserted into the cylinder body 1 from the upper end of the cylinder body 1, and the lower end of the intake pipe 2 is closed. An air outlet (not labeled in the figure) is provided on the side of the intake pipe 2, and the intake pipe 2 communicates with the inner cavity through the air outlet; one end of the exhaust pipe 3 is inserted into the inner cavity of the cylinder body 1 at a certain distance from the intake pipe 2, and the other end of the exhaust pipe 3 is located outside the cylinder body 1; the reinforcing plate 4 is fixed on the inner wall of the cylinder body 1 and surrounds the exhaust pipe 3. At least one filter hole 44 is provided on the reinforcing plate 4, and a filter screen 45 is arranged in the filter hole 44; inserted into.

[0036] Specifically, both the liquid storage device 10 and the compressor body are important components of the compressor. The two are interconnected and used in cooperation. The compressor body compresses the low-temperature and low-pressure refrigerant entering it. After converting the low-temperature and low-pressure refrigerant into a high-temperature and high-pressure refrigerant, the high-temperature and high-pressure refrigerant is sent back to the refrigerant circulation system. The liquid storage device 10 sucks the refrigerant from the compressor body, separates the oil and gas from the refrigerant, and sends the refrigerant after oil and gas separation back to the compressor body. The compressor can be used in electrical equipment with heat exchange functions such as refrigerators, freezers, air conditioners, and air coolers to compress the refrigerant.

[0037] As Figures 1 to 3 shown, the liquid storage device 10 includes a cylinder body 1, an intake pipe 2, an exhaust pipe 3, and a reinforcing plate 4. An air inlet is provided at the upper end of the cylinder body 1, and an air outlet is provided at the lower end of the cylinder body 1. The intake pipe 2 is installed on the air inlet. The exhaust pipe 3 includes a straight pipe 31 and a bent pipe 32. The bent pipe 32 extends into the cylinder body 1 through the air outlet and is connected to the straight pipe 31. The reinforcing plate 4 is fixed on the inner wall of the cylinder body 1, and the straight pipe 31 is inserted into the central hole 43 of the reinforcing plate 4.

[0038] Among them, the cylinder body 1 includes a cylindrical main body, an upper head, and a lower head. The cylindrical main body is arranged between the upper head and the lower head and is connected to the upper head and the lower head to form a closed cylindrical structure.

[0039] The cylinder body 1 has an air inlet, an exhaust port, and an inner cavity (not shown by reference numerals in the figure). The intake pipe 2 is connected to the air inlet of the cylinder body 1, the exhaust pipe 3 is connected to the air outlet of the cylinder body 1, and the intake pipe 2 and the exhaust pipe 3 communicate with each other through the inner cavity.

[0040] The air inlet of the intake pipe 2 is opened on the upper end surface, the lower end surface of the intake pipe 2 is closed, the air outlet of the intake pipe 2 is opened on the side surface of the intake pipe 2, the air inlet and the air outlet of the intake pipe 2 communicate with each other, the lower end of the intake pipe 2 is inserted into the cylinder body 1, and the intake pipe 2 communicates with the inner cavity through the air outlet.

[0041] In this embodiment, the air outlet of the intake pipe 2 is arranged on the side surface of the intake pipe 2 instead of its bottom surface. Thus, the gas-liquid mixture entering the inner cavity from the intake pipe 2 will not directly fall into the exhaust pipe 3 below it, thereby avoiding garbage directly falling into the exhaust pipe 3 and being unable to be filtered.

[0042] Please continue to refer to Figure 1 , the exhaust pipe 3 includes a straight pipe 31 and a bent pipe 32. The straight pipe 31 is arranged inside the cylinder body 1. One end of the bent pipe 32 is connected to the straight pipe 31, and the other end of the bent pipe 32 extends out of the cylinder body 1 from the lower end of the cylinder body 1. Both the straight pipe 31 and the intake pipe 2 are inserted into the inner cavity of the cylinder body 1, but maintain a certain distance and do not contact each other.

[0043] In this embodiment, the straight pipe 31 is a steel pipe, and both the straight pipe 31 and the intake pipe 2 are vertically arranged. Preferably, the central axis of the intake pipe 2 coincides with the central axis of the straight pipe 31.

[0044] Please continue to refer to Figure 1 and Figure 2 , the reinforcing plate 4 includes a reinforcing plate bottom wall 41 and a reinforcing plate side wall 42. The reinforcing plate side wall 42 surrounds the reinforcing plate bottom wall 41 and vertically extends upward from the edge of the reinforcing plate bottom wall 41. A reinforcing plate mounting portion (not shown in the figure) is provided on the reinforcing plate side wall 42, and a reinforcing plate fixing portion (not shown in the figure) is provided on the inner wall of the cylinder body 1. The reinforcing plate fixing portion and the reinforcing plate mounting portion cooperate with each other to limit the movement of the reinforcing plate 4. Through the mutually cooperating reinforcing plate fixing portion and reinforcing plate mounting portion, the reinforcing plate 4 can be fixed to the inner wall of the cylinder body 1, thereby realizing the effective fixing of the reinforcing plate 4. In addition, the reinforcing plate side wall 42 increases the contact area between the reinforcing plate 4 and the inner wall, so that it can still maintain a stable connection with the cylinder body 1 under the impact of the refrigerant and is not easily detached or loosened.

[0045] Please continue to refer to Figures 1 to 3, at least one filtering hole 44 is provided on the bottom wall 41 of the reinforcing plate. A filter screen 45 is correspondingly arranged below the filtering hole 44. The filter screen 45 is used to filter the gas-liquid mixture in the inner cavity to prevent garbage from entering the bottom oil sump. Herein, the shape, size, quantity, and opening position of the filtering hole 44 are not limited. Those skilled in the art can set the shape, size, quantity, and opening position of the filtering hole 44 according to actual requirements.

[0046] In this embodiment, the filter screen 45 is fixed in the filtering hole 44 and surrounds the edge of the filtering hole 44. The filter screen 45 has a spherical structure that bulges from top to bottom (i.e., bulges towards the bottom of the cylinder 1). Designing the filter screen 45 as a spherical structure can utilize the principle of the large surface area of the spherical surface to increase the contact area between the filter screen and the refrigerant, so as to improve the filtering effect.

[0047] In other embodiments, the filter screen 45 can also be fixedly arranged outside the filtering hole 44. Please refer to Figure 7 and Figure 8 , which is a schematic structural diagram of the reinforcing plate of another embodiment of the present invention. As shown in Figure 7 and Figure 8 , the filter screen 45 is fixed outside the filtering hole 44 and surrounds the edge of the filtering hole 44. The range of the filter screen 45 is larger than that of the filtering hole 44. The reinforcing plate 4 has an inclined area, and the inclined area is located between the edge position of the filtering hole 44 and the fixing position of the filter screen 45. The inclination direction of the inclined area is towards the center of the filtering hole 44, that is, the edge of the filtering hole 44 forms a downwardly inclined structure, so that the gas-liquid mixture can flow smoothly into the filtering hole 44.

[0048] In this embodiment, the side wall 42 of the reinforcing plate is a circular ring structure. The outer periphery of the circular ring structure fits with the inner periphery of the cylinder 1, and the inner periphery of the circular ring structure fits with the outer periphery of the straight pipe 31. Preferably, the at least one filtering hole 44 is arranged between the inner periphery and the outer periphery of the circular ring structure and is evenly distributed along the circumferential direction.

[0049] In this embodiment, the reinforcing plate 4 is located below the middle position of the cylinder 1. Preferably, the reinforcing plate 4 is located at the bottom of the cylinder 1. For example, the reinforcing plate 4 is located at or near the connection position between the lower head and the cylindrical body. Correspondingly, the filter screen 45 on the reinforcing plate 4 is also located at the bottom of the cylinder 1. In this way, the effective volume of the liquid storage device 10 can be effectively increased.

[0050] In this embodiment, the reinforcing plate 4 can not only partition the inner cavity of the liquid storage cylinder body and fix the exhaust pipe 3 inside the liquid storage cylinder body, but also a filter screen 45 with a filtering function is arranged on the reinforcing plate 4, which can replace the filter screen assembly, the bracket and the partition plate, thereby reducing the components of the liquid storage device and simplifying the assembly process of the liquid storage device.

[0051] Correspondingly, this embodiment also provides a compressor, and the compressor includes the liquid storage device 10 as described above. For details, please refer to the above text and will not be elaborated here.

[0052]

Embodiment II

[0053] Please refer to Figures 4 to 6 , which is a schematic structural diagram of the liquid storage device of Embodiment II of the present invention. As Figures 4 to 6 shown, the liquid storage device 20 includes: a cylinder body 1, an inlet pipe 2, an exhaust pipe 3 and a reinforcing plate 4; the cylinder body 1 has an inner cavity, the inlet pipe 2 is inserted into the cylinder body 1 from the upper end of the cylinder body 1, and the lower end of the inlet pipe 2 is closed. An air outlet (not shown in the figure) is arranged on the side surface of the inlet pipe 2, and the inlet pipe 2 is communicated with the inner cavity through the air outlet; one end of the exhaust pipe 3 is inserted into the inner cavity of the cylinder body 1 at a certain distance from the inlet pipe 2, and the other end of the exhaust pipe 3 is located outside the cylinder body 1; the reinforcing plate 4 is fixed on the inner wall of the cylinder body 1 and surrounds the exhaust pipe 3, and at least one filtering hole 44 is formed in the reinforcing plate 4, and a filter screen 45 is inserted into the filtering hole 44.

[0054] Specifically, the cylinder body 1 includes a first cylinder body unit 11 and a second cylinder body unit 12, the first cylinder body unit 11 and the second cylinder body unit 12 are arranged coaxially and oppositely, and the first cylinder body unit 11 and the second cylinder body unit 12 are connected to form a closed cylindrical structure.

[0055] An air inlet is arranged at one end of the first cylinder body unit 11 facing away from the second cylinder body unit 12, and the inlet pipe 2 is hermetically connected to the air inlet and extends into the inner cavity of the first cylinder body unit 11. An air outlet is arranged at one end of the second cylinder body unit 12 facing away from the first cylinder body unit 11, and the exhaust pipe 3 is hermetically connected to the air outlet and communicates with the inner cavity of the first cylinder body unit 11.

[0056] The difference between this embodiment and Embodiment I lies in the different cylinder body structures. Compared with the traditional cylinder body structure with an upper head and a lower head, the cylinder body structure composed of two cylinder body units can simplify the assembly process of the liquid storage device, improve the assembly accuracy of the liquid storage device, avoid welding leakage, which is not only beneficial to reducing production costs, but also can improve the overall reliability of the compressor.

[0057] In addition, the structure of the reinforcing plate 4 is also different. In this embodiment, the side wall 42 of the reinforcing plate extends vertically downward from the edge of the bottom wall 41 of the reinforcing plate, rather than vertically upward.

[0058] Correspondingly, this embodiment also provides a compressor, which includes the liquid receiver 20 as described above. For details, please refer to the above text and will not be elaborated here.

[0059] In other embodiments, the liquid receiver may adopt the same cylinder body 1 as in the second embodiment, and at the same time adopt the same reinforcing plate 4 as in the first embodiment, that is, adopt a cylinder structure composed of two cylinder units, and at the same time adopt a reinforcing plate 4 in which the side wall 42 of the reinforcing plate extends vertically upward from the edge of the bottom wall 41 of the reinforcing plate.

[0060] In other embodiments, the liquid receiver may also adopt the same cylinder body 1 as in the first embodiment, and at the same time adopt the same reinforcing plate 4 as in the second embodiment, that is, while adopting the traditional cylinder structure with an upper head and a lower head, adopt a reinforcing plate 4 in which the side wall 42 of the reinforcing plate extends vertically downward from the edge of the bottom wall 41 of the reinforcing plate.

[0061] It should be noted that the various embodiments in this specification are described in a progressive manner. The key point of each embodiment is to illustrate the differences from other embodiments. The same or similar parts among the various embodiments can be referred to each other.

[0062] In summary, for the liquid receiver and the compressor of the present invention, by adopting a reinforcing plate with filter holes and cooperating with an intake pipe with side exhaust, it can not only prevent garbage from falling into the exhaust pipe, but also increase the effective volume of the liquid receiver, reduce the components of the liquid receiver, simplify the assembly process of the liquid receiver, and thus reduce the manufacturing costs of the liquid receiver and the compressor.

[0063] The above content is a further detailed description of the present application in combination with specific preferred embodiments. It cannot be determined that the specific implementation of the present application is only limited to these descriptions. For those of ordinary skill in the technical field to which the present application belongs, without departing from the concept of the present application, several simple deductions or substitutions can be made, and all should be regarded as belonging to the protection scope of the present application.
