Embodiments for Carrying Out the Invention

[0020] Hereinafter, with reference to the drawings in the embodiments of the present application, the technical aspects in the embodiments of the present application will be clearly and completely described. It goes without saying that the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present application.

[0021] It should be noted that when an assembly is said to be "mounted" on another assembly, it may be directly mounted on the other assembly, or there may be an assembly placed in between. When one assembly is considered to be "provided" on another assembly, it may be directly provided on the other assembly, or there may be an assembly placed in between at the same time. When one assembly is considered to be "fixed" on another assembly, it may be directly fixed on the other assembly, or there may be an assembly placed in between at the same time.

[0022] Unless otherwise defined, all technical and scientific terms used in the present application have the same meaning as commonly understood by those skilled in the art of the present application. The terms used in the specification of the present application are only for specifically explaining the purpose of the embodiments and are not intended to limit the present application. The term "and / or" used in the present application includes any and all combinations of one or more of the related items.

[0023] Referring to FIGS. 1, 2, 5 and 6, the present application provides a gas-liquid separator 100 including a housing 1, an inlet pipe (not shown), an exhaust pipe 2, a filtering member 3, and a fixing holder 4. A liquid storage chamber 11 is provided in the housing 1. At least a part of the exhaust pipe 2 is provided in the liquid storage chamber 11, and a filtering port 21 is provided at a portion of the exhaust pipe 2 located in the liquid storage chamber 11. The filtering member 3 is fixedly connected to the filtering port 21 of the exhaust pipe 2 so as to filter the medium entering the exhaust pipe 2 from the filtering port 21.

[0024] Normally, the refrigerant in a gas-liquid two-phase state enters the liquid storage chamber 11 from the inlet pipe, and a part of the lubricating oil for the compressor is mixed in the refrigerant. After the refrigerant enters the liquid storage chamber 11, the gaseous refrigerant rises and enters the exhaust pipe 2, and the liquid refrigerant mixed with the lubricating oil directly settles at the bottom of the liquid storage chamber 11. Since the liquid refrigerant and the lubricating oil have different densities and cannot dissolve in each other, at the bottom of the liquid storage chamber 11, the liquid refrigerant and the lubricating oil become layered under the action of gravity, and the lubricating oil floats on the liquid refrigerant. Then, the lubricating oil enters the exhaust pipe 2 through the filtering member 3 and returns to the compressor together with the gaseous refrigerant. The liquid refrigerant remaining at the bottom of the liquid storage chamber 11 can also be vaporized, rise in the liquid storage chamber 11, enter the exhaust pipe 2, and finally return to the compressor.

[0025] In this embodiment, as shown in FIGS. 1, 2, 5 and 6, the filtering member 3 is fixedly connected to the exhaust pipe 2, and the fixing holder 4 fixedly connects the housing 1 and the filtering member 3, so that the fixing connection between the exhaust pipe 2 and the housing 1 is realized. Compared with the exhaust pipe 2, it is easier to fixedly connect the fixing holder 4 to the filtering member 3, and the difficulty of connecting the fixing holder 4 and the filtering member 3 is low. Therefore, the present application greatly reduces the difficulty of connecting the exhaust pipe 2 and the housing 1 by fixedly connecting the fixing holder 4 to the filtering member 3.

[0026] It should be noted that the fixed connection includes welding and engagement, that is, the filtering member 3 may be engaged with the filtering port 21 of the exhaust pipe 2, or may be welded to the filtering port 21 of the exhaust pipe 2. Similarly, the fixed holder 4 may be welded to the housing 1, or may be engaged with the housing 1. The fixed holder 4 may be welded to the filtering member 3, or may be engaged with the filtering member 3. Moreover, without being limited thereto, the fixed connection may include connection methods such as screw connection and rivet connection.

[0027] Furthermore, as shown in FIG. 2, the filtering member 3 includes a filter 32, a connector 33, and a main seat body 31 connecting the filter 32 and the connector 33. The connector 33 enters the filtering port 21 and is fixedly connected to the exhaust pipe 2. By the connector 33 entering the filtering port 21 and being fixedly connected to the exhaust pipe 2, the connection strength between the filtering member 3 and the exhaust pipe 2 is increased. Specifically, the main seat body 31 is in a tapered tubular shape, and the outer diameter of the main seat body 31 gradually increases from one end close to the connector 33 to the other end away from the connector 33. The filter 32 is in a cylindrical shape and is covered on one end of the main seat body 31 away from the connector 33. This is advantageous for increasing the filtering area of the filter 32, and effectively improves the oil return efficiency of the gas-liquid separator 100.

[0028] In one embodiment, as shown in FIGS. 1 to 7, the fixed holder 4 is provided with an engaging hole 41, and the fixed holder 4 is fitted outside the connector 33 through the engaging hole 41. In this way, the assembly of the fixed holder 4 and the filtering member 3 becomes more firm. Specifically, after the fixed holder 4 is fitted outside the connector 33 through the engaging hole 41, the connector 33 is inserted into the filtering port 21 and fixedly connected to the exhaust pipe 2. Furthermore, by welding the outside of the connector 33 and the engaging hole 41 of the fixed holder 4, the firmness of the connection between the fixed holder 4 and the filtering member 3 is further improved.

[0029] Furthermore, as shown in FIG. 2, the portion of the fixed holder 4 where the engagement hole 41 is provided abuts between the exhaust pipe 2 and the main seat body 31. Thereby, one end connected to the filtering member 3 of the fixed holder 4 is less likely to loosen, and the structural strength of the gas-liquid separator 100 is effectively increased.

[0030] In one embodiment, as shown in FIGS. 1 to 4, one end of the fixed holder 4 is welded to the inner wall of the housing 1, and the engagement hole 41 is provided at the other end. That is, one end of the fixed holder 4 is connected to the housing 1, and the other end is connected to the filtering member 3. Thereby, the structure of the fixed holder 4 becomes simpler, which is advantageous for the processing and manufacturing of the gas-liquid separator 100. Further, the fixed holder 4 includes a first connection plate 42 and a second connection plate 43. The first connection plate 42 and the second connection plate 43 are connected in an L shape. One end of the first connection plate 42 away from the second connection plate 43 is connected to the housing 1, and one end of the second connection plate 43 away from the first connection plate 42 is connected to the filtering member 3. In this way, the structural strength of the fixed holder 4 is increased, and the fixed holder 4 is less likely to bend and deform.

[0031] In another embodiment, as shown in FIGS. 5 to 7, both ends of the fixed holder 4 are welded to the inner wall of the housing 1, and the engagement hole 41 is provided in the middle portion of the fixed holder 4. Thereby, the welding points between the fixed holder 4 and the housing 1 are increased, and the connection strength between the fixed holder 4 and the housing 1 is increased. Specifically, both ends of the fixed holder 4 are bent at 90° to form a flange structure 44, and the fixed holder 4 is welded to the housing 1 by the flange structure 44. Thereby, the welding area between the fixed holder 4 and the housing 1 is further increased, and the welding strength between the fixed holder 4 and the housing 1 is increased.

[0032] In one embodiment, as shown in FIGS. 4 to 7, if the inner diameter of the engagement hole 41 is d and the width of the fixing holder 4 is h, then d and h satisfy the relational expression: 0.3h ≦ d ≦ 0.7h. Since d ≧ 0.3h, that is, h ≦ 10d / 3, it is possible to prevent the width of the fixing holder 4 from being too large and affecting the degree of freedom of assembly of the fixing holder 4 within the liquid storage chamber 11. Since d ≦ 0.7h, it is possible to prevent the inner diameter of the engagement hole 41 from being too large and affecting the structural strength of the fixing holder 4.

[0033] As shown in FIG. 8, the present application further provides an air conditioner 200 including the gas-liquid separator 100 described in any of the above embodiments.

[0034] In the gas-liquid separator 100 and the air conditioner 200 provided by the present application, since the filtering member 3 is fixedly connected to the exhaust pipe 2 and the fixing holder 4 fixedly connects the housing 1 and the filtering member 3, the fixed connection between the exhaust pipe 2 and the housing 1 is realized. Compared with the exhaust pipe 2, it is easy to fixedly connect the fixing holder 4 to the filtering member 3, and since the degree of difficulty in connecting the fixing holder 4 and the filtering member 3 is low, the present application greatly reduces the degree of difficulty in connecting the exhaust pipe 2 and the housing 1 by fixedly connecting the fixing holder 4 to the filtering member 3.

[0035] Each of the technical features of the above-described embodiments can be arbitrarily combined. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should all be regarded as within the scope described in this specification.

[0036] Those skilled in the art should recognize that the above embodiments are merely for explaining the present application and are not used as limitations on the present application. Within the scope of the substantial spirit of the present application, any appropriate modifications and changes made to the above embodiments all fall within the scope for which the present application seeks protection.
