It should be understood that a person of ordinary skill in the art can recognize that the present application can be implemented without using these specific details.

Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in the present application.

[0027] like Figures 1 to 3 As shown, on the one hand, an embodiment of the present application provides a gas-liquid separator 1, which includes a shell 10, an air inlet pipe 20, an air outlet pipe 30 and a diverter 40, which can effectively reduce the use noise and improve the user's experience.

[0028] An inner cavity 11 is provided inside the shell 10, and the inner cavity 11 is well sealed. An air inlet pipe 20 and an air outlet pipe 30 extend from the outside of the shell 10 to the inner cavity 11, respectively. The air inlet pipe 20 is used to input the refrigerant in a gas-liquid mixed state into the inner cavity 11, and the air outlet pipe 30 is used to output the gaseous refrigerant obtained after separation to the outside of the inner cavity 11; when the gas-liquid separator 1 is arranged at the front end of the compressor, the output end of the air outlet pipe 30 can be connected to the return air port of the compressor to allow the gaseous refrigerant to flow back into the compressor.

[0029] The flow divider 40 is disposed in the inner cavity 11 and connected to the output end of the air inlet pipe 20 to divert the fluid input from the air inlet pipe 20 to the inner cavity 11. Here, the flow divider 40 can separate the gas-liquid mixed refrigerant input into the inner cavity 11 into multiple streams of fluid, so that each stream of fluid is independently and slowly injected into the inner cavity 11. By separating the gas-liquid mixed refrigerant into multiple streams of fluid, the impact kinetic energy of each stream of fluid can be reduced; when each stream of fluid contacts the side wall of the inner cavity 11, the impact force and impact noise of each stream of fluid on the side wall of the inner cavity 11 are both small, which can effectively eliminate or at least greatly reduce the noise of the gas-liquid separator 1 when in use, and effectively improve the user experience.

[0030] The specific structure of the flow divider 40 can be determined according to actual needs, and the present embodiment of the application does not limit this. Figures 1 to 4As shown, in some embodiments, the flow divider 40 may have a first end 41 and a second end 42 that are arranged opposite to each other and in communication, the first end 41 being connected to the output end of the air inlet pipe 20, and the second end 42 being provided with a plurality of flow divider holes 421. By providing a plurality of flow divider holes 421 at the second end 42, the gas-liquid mixed refrigerant flowing from the first end 41 to the second end 42 may flow out from each of the flow divider holes 421 at the second end 42, and the refrigerant flowing out of each of the flow divider holes 421 may form a stream of fluid, thereby achieving a flow divider effect on the gas-liquid mixed refrigerant input into the inner cavity 11.

[0031] The distribution of the plurality of diverter holes 421 at the second end 42 can be determined according to actual needs, and various distribution methods such as linear distribution, annular distribution or irregular distribution can be adopted, and the embodiments of the present application are not limited to this. In some examples, the second end 42 can be provided with a plurality of diverter hole groups 422, and the plurality of diverter hole groups 422 can be sequentially spaced outward from the center of the second end 42, and the diverter hole groups 422 located on the outside surround the diverter hole groups 422 located on the inside; each diverter hole group 422 includes a plurality of diverter holes 421 arranged in an annular manner around the center of the second end 42, so that each diverter hole group 422 is respectively arranged around the center of the second end 42. By distributing the multiple diversion holes 421 as above, the gas-liquid mixed refrigerant input into the inner cavity 11 can be evenly diverted into multiple fluid streams, so that each fluid stream flows to a different position on the side wall of the inner cavity 11, thereby avoiding the fluids from flowing concentratedly to the same position and causing a more obvious impact, thereby effectively reducing the impact noise during refrigerant injection, thereby eliminating or at least greatly reducing the operating noise of the gas-liquid separator 1 and improving the user experience.

[0032] In some examples, the direction of the diverter hole 421 and the side wall of the inner cavity 11 are inclined so that the fluid flowing out of the diverter hole 421 can flow slowly and obliquely toward the side wall of the inner cavity 11, thereby reducing the impact noise caused by the direct downward impact of the fluid and improving the gas-liquid separation effect of the refrigerant in the gas-liquid separator 1.

[0033] The angle between the direction of the diverter hole 421 and the side wall of the inner cavity 11 can be determined according to actual needs, and the embodiment of the present application does not limit this. For example, the angle between the direction of the diverter hole 421 and the side wall of the inner cavity 11 can be 15° to 80°. Within this angle range, the impact noise during the injection of the refrigerant can be further reduced, and the gas-liquid separation effect of the refrigerant in the gas-liquid separator 1 can be further improved.

[0034] In some embodiments, the inner diameter of the flow divider 40 can be gradually increased from the first end 41 to the second end 42, so that the flow cavity of the flow divider 40 is a trumpet structure that gradually expands along the fluid flow direction; when the refrigerant flows from the first end 41 to the second end 42, the flow velocity of the refrigerant gradually decreases due to the gradual increase in the inner diameter of the flow cavity. In this way, when the refrigerant flows to the flow diversion hole 421 at the second end 42, the flow velocity and fluid kinetic energy of the refrigerant have been reduced to a relatively low level, so that the single stream of fluid formed after the diversion has a smaller impact kinetic energy, further reducing the impact noise when the refrigerant is injected, and making the gas-liquid separation effect more sufficient.

[0035] In some examples, the inner diameter of the second end 42 may be 2 to 10 times, for example, 2 times, 3 times, 4.5 times, 5 times, 6 times, 6.5 times, 7 times, 8 times, 9 times or 10 times, the inner diameter of the first end 41. Within this inner diameter ratio range, the impact noise during the injection of the refrigerant is low, and the gas-liquid separation effect is high, and the separation efficiency can reach 97.8%.

[0036] In some embodiments, the height of the output end of the flow divider 40, that is, the second end 42, can be set to be lower than the height of the input end of the gas outlet pipe 30. In other words, the output end of the flow divider 40 is located in the lower area of ​​the input end of the gas outlet pipe 30, so that the gas-liquid mixed refrigerant input from the flow divider 40 into the inner cavity 11 first passes through the gas-liquid separation effect of the inner cavity 11, and the formed gaseous refrigerant can be discharged from the input end of the gas outlet pipe 30 to the outside of the inner cavity 11, thereby ensuring the gas-liquid separation effect.

[0037] The shape of the air intake pipe 20 can be determined according to actual needs, and the embodiment of the present application does not limit this. In some embodiments, the air intake pipe 20 can be a straight pipe. Here, the straight pipe can extend vertically or obliquely in the up and down direction, so that the input end of the air intake pipe 20 is located at the top of the straight pipe, and the output end is located at the bottom of the straight pipe, and the diverter 40 can be arranged at the bottom of the straight pipe.

[0038] In some embodiments, the height of the input end of the air outlet pipe 30 can be set to be lower than the height of the output end of the air outlet pipe 30. In other words, the input end of the air outlet pipe 30 is located at the lower side of the output end of the air outlet pipe 30; in this way, after the refrigerant passes through the gas-liquid separation effect of the inner cavity 11, the gaseous refrigerant formed can flow upward and be discharged along the air outlet pipe 30, while the liquid refrigerant formed can only be deposited at the bottom of the inner cavity 11, and cannot be discharged along the air outlet pipe 30 against its own weight, thereby ensuring the gas-liquid separation effect.

[0039] The shape of the air outlet pipe 30 can be determined according to actual needs, and the embodiment of the present application does not limit this. In some examples, the air outlet pipe 30 can be a U-shaped pipe. The U-shaped opening of the U-shaped pipe is arranged upward, so that the curved section of the U-shaped pipe is located at the bottom, and the straight pipe section is located on both sides, and the input end and the output end of the air outlet pipe 30 are respectively formed at the opposite ends of the U-shaped pipe.

[0040] In some embodiments, the gas-liquid separator 1 may further include a fixing frame 50. The housing 10 is disposed on the fixing frame 50, and the fixing frame 50 is used to connect and fix with other devices such as a compressor.

[0041] On the other hand, an embodiment of the present application provides an air conditioner, which includes the gas-liquid separator 1 provided in any of the above embodiments. The type of the air conditioner can be determined according to actual needs, and can be, for example, a wall-mounted air conditioner, a cabinet air conditioner, a window air conditioner, etc., which is not limited in the embodiment of the present application. The air conditioner provided in the embodiment of the present application has the above-mentioned gas-liquid separator 1, which can effectively reduce the use noise and improve the user's experience.

[0042] The gas-liquid separator and air conditioner provided in the embodiments of the present application are introduced in detail above. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea; at the same time, for technical personnel in this field, according to the idea of ​​the present application, there will be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
