Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] The flow path switching module 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0030] like Figures 1-4 As shown, the flow path switching module 100 according to an embodiment of the present invention includes a first control valve 11, a second control valve 12, a third control valve 13 and a fourth control valve 14.

[0031] Specifically, the first control valve 11, the second control valve 12, the third control valve 13, and the fourth control valve 14 are connected sequentially. The first control valve 11 and the second control valve 12 have a first connection port 21; the second control valve 12 and the third control valve 13 have a second connection port 22; the third control valve 13 and the fourth control valve 14 have a third connection port 23; and the fourth control valve 14 and the first control valve 11 have a fourth connection port 24. All four connection ports (11, 22, 23, and 24) can be connected to the air conditioning system, allowing for the switching of the air conditioning system's flow path.

[0032] One side of the flow path switching module 100 is the connection side, where the first connection port 21, the second connection port 22, the third connection port 23, and the fourth connection port 24 are all located. This allows the end of the flow path switching module 100 facing away from the connection side to be submerged in water when the first connection port 21, the second connection port 22, the third connection port 23, and the fourth connection port 24 are welded to the pipeline. In this case, the first connection port 21, the second connection port 22, the third connection port 23, and the fourth connection port 24 are above the water surface, while the remaining area is below the water surface. This allows for better cooling of the flow path switching module 100, improving the cooling effect and reducing the risk of functional failure due to overheating during welding. It also avoids the need to wrap the flow path switching module 100 with a wet cloth, shortening the processing time.

[0033] According to the embodiment of the present invention, the flow path switching module 100 has one side as the connection side. By ensuring that the first connection port 21, the second connection port 22, the third connection port 23, and the fourth connection port 24 are all located on the connection side, when the first connection port 21, the second connection port 22, the third connection port 23, and the fourth connection port 24 of the flow path switching module 100 are welded to the pipeline, it is convenient to immerse the end of the flow path switching module 100 away from the connection side in water. This allows for better cooling of the flow path switching module 100, improves the cooling effect, reduces the problem of functional failure of the flow path switching module 100 due to overheating during welding, and avoids the need to wrap the flow path switching module 100 with a wet cloth, thus shortening the working time.

[0034] In some embodiments of this utility model, such as Figures 1-4 As shown, the first connection port 21, the second connection port 22, the third connection port 23, and the fourth connection port 24 all face the same direction and are all facing the connection side. Therefore, when the end of the flow path switching module 100 away from the connection side is immersed in water, the first connection port 21, the second connection port 22, the third connection port 23, and the fourth connection port 24 are all positioned upwards, which facilitates the connection of the first connection port 21, the second connection port 22, the third connection port 23, and the fourth connection port 24 to the pipeline.

[0035] Of course, this utility model is not limited to this. When the first connection port 21, the second connection port 22, the third connection port 23 and the fourth connection port 24 are oriented in the same direction, the first connection port 21, the second connection port 22, the third connection port 23 and the fourth connection port 24 can be oriented in other directions other than the connection side. Of course, the first connection port 21, the second connection port 22, the third connection port 23 and the fourth connection port 24 can be oriented in different directions.

[0036] In some embodiments of this utility model, such as Figures 1-4As shown, at least one of the first control valve 11, the second control valve 12, the third control valve 13, and the fourth control valve 14 has a U-shaped structure with the opening of the U-shape facing the connection side. This facilitates the bending of the first control valve 11, the second control valve 12, the third control valve 13, or the fourth control valve 14 so that the first connection port 21, the second connection port 22, the third connection port 23, and the fourth connection port 24 are simultaneously located on the connection side of the flow path switching module 100. When the first connection port 21, the second connection port 22, the third connection port 23, and the fourth connection port 24 of the flow path switching module 100 are welded to the pipeline, it is convenient to immerse the end of the flow path switching module 100 away from the connection side in water. This allows for better cooling of the flow path switching module 100, improves the cooling effect, reduces the problem of functional failure of the flow path switching module 100 due to overheating during welding, and avoids the need to wrap the flow path switching module 100 with a wet cloth, shortening the working time.

[0037] For example, in Figures 1-4 In the example shown, the first control valve 11, the second control valve 12, the third control valve 13, and the fourth control valve 14 are all U-shaped structures, and the openings of the U-shaped structures all face the connection side.

[0038] In some embodiments of this utility model, such as Figures 1-4 As shown, the axes of the first control valve 11 and the second control valve 12 are located in the first plane, and the axes of the third control valve 13 and the fourth control valve 14 are located in the second plane. The first and second planes are parallel. This simplifies the structure of the flow path switching module 100, reduces the space occupied by the flow path switching module 100, and ensures that when the first connection port 21, the second connection port 22, the third connection port 23, and the fourth connection port 24 of the flow path switching module 100 are welded to the pipeline, it is convenient to immerse the end of the flow path switching module 100 away from the connection side in water, which can better cool the flow path switching module 100, improve the cooling effect of the flow path switching module 100, reduce the problem of functional failure of the flow path switching module 100 due to welding overheating, and avoid the need to wrap the flow path switching module 100 with a wet cloth, shortening the working time.

[0039] In some embodiments of this utility model, such as Figures 1-4As shown, the first control valve 11 and the second control valve 12 are arranged in sequence in the first direction, and the fourth control valve 14 and the third control valve 13 are arranged in sequence in the first direction. The first control valve 11 and the second control valve 12 constitute the first valve group, and the third control valve 13 and the fourth control valve 14 constitute the second valve group. Along the first direction, the size of the first valve group is the same as the size of the second valve group. The first direction is parallel to the first plane and the second plane. This allows the outer contour of the flow path switching module 100 when viewed from below to form a parallelogram structure, further simplifying the structure of the flow path switching module 100 and reducing the space occupied by the flow path switching module 100. At the same time, it ensures that when the first connection port 21, the second connection port 22, the third connection port 23, and the fourth connection port 24 of the flow path switching module 100 are welded to the pipeline, it is convenient to immerse the end of the flow path switching module 100 away from the connection side in water, which can better cool down the flow path switching module 100, improve the cooling effect of the flow path switching module 100, reduce the problem of functional failure of the flow path switching module 100 due to overheating during welding, and avoid wrapping the flow path switching module 100 with a wet cloth, thus shortening the working time.

[0040] In some embodiments of this utility model, such as Figures 1-4 As shown, the two ends of the first valve group are flush with the two ends of the second valve group. This allows the outer contour of the flow path switching module 100 to form a cuboid structure, further simplifying the structure of the flow path switching module 100, reducing the space occupied by the flow path switching module 100, and ensuring that when the first connection port 21, the second connection port 22, the third connection port 23, and the fourth connection port 24 of the flow path switching module 100 are welded to the pipeline, it is convenient to immerse the end of the flow path switching module 100 away from the connection side in water, which can better cool down the flow path switching module 100, improve the cooling effect of the flow path switching module 100, reduce the problem of functional failure of the flow path switching module 100 due to welding overheating, and avoid wrapping the flow path switching module 100 with a wet cloth, shortening the working time.

[0041] In some embodiments of this utility model, the first control valve 11 and the second control valve 12 are arranged sequentially in the first direction, and the fourth control valve 14 and the third control valve 13 are arranged sequentially in the first direction. The first control valve 11 and the second control valve 12 constitute a first valve group, and the third control valve 13 and the fourth control valve 14 constitute a second valve group. Along the first direction, the size of the first valve group is smaller than the size of the second valve group. The first direction is parallel to the first plane and the second plane. This allows the outer contour of the flow path switching module 100 when viewed from below to form a trapezoidal structure, simplifying the structure of the flow path switching module 100, reducing the space occupied by the flow path switching module 100, and ensuring that when the first connection port 21, the second connection port 22, the third connection port 23, and the fourth connection port 24 of the flow path switching module 100 are welded to the pipeline, it is convenient to immerse the end of the flow path switching module 100 away from the connection side in water, which can better cool down the flow path switching module 100, improve the cooling effect of the flow path switching module 100, reduce the problem of functional failure of the flow path switching module 100 due to welding overheating, and avoid wrapping the flow path switching module 100 with a wet cloth, shortening the working time.

[0042] In some embodiments of this utility model, along the first direction, the first valve group is located between the two ends of the second valve group. This simplifies the structure of the flow path switching module 100, reduces the space occupied by the flow path switching module 100, and ensures that when the first connection port 21, the second connection port 22, the third connection port 23, and the fourth connection port 24 of the flow path switching module 100 are welded to the pipeline, it is convenient to immerse the end of the flow path switching module 100 away from the connection side in water, which can better cool down the flow path switching module 100, improve the cooling effect of the flow path switching module 100, reduce the problem of functional failure of the flow path switching module 100 due to welding overheating, and avoid the need to wrap the flow path switching module 100 with a wet cloth, shortening the working time.

[0043] In some embodiments of this utility model, the first valve group and the second valve group partially overlap along the first direction. The dimensions of the first valve group and the second valve group may be the same or different along the first direction. This simplifies the structure of the flow path switching module 100, reduces the space occupied by the flow path switching module 100, and ensures that when the first connection port 21, the second connection port 22, the third connection port 23, and the fourth connection port 24 of the flow path switching module 100 are welded to the pipeline, it is convenient to immerse the end of the flow path switching module 100 away from the connection side in water. This allows for better cooling of the flow path switching module 100, improves the cooling effect, reduces the problem of functional failure of the flow path switching module 100 due to welding overheating, and avoids the need to wrap the flow path switching module 100 with a wet cloth, shortening the working time.

[0044] In some embodiments of this utility model, the first valve group and the second valve group are spaced apart along the first direction. The dimensions of the first valve group and the second valve group may be the same or different along the first direction. This simplifies the structure of the flow path switching module 100, reduces the space occupied by the flow path switching module 100, and ensures that when the first connection port 21, the second connection port 22, the third connection port 23, and the fourth connection port 24 of the flow path switching module 100 are welded to the pipeline, it is convenient to immerse the end of the flow path switching module 100 away from the connection side in water. This allows for better cooling of the flow path switching module 100, improves the cooling effect, reduces the problem of functional failure of the flow path switching module 100 due to welding overheating, and avoids the need to wrap the flow path switching module 100 with a wet cloth, shortening the working time.

[0045] In some embodiments of this utility model, the axes of the first control valve 11, the second control valve 12, the third control valve 13, and the fourth control valve 14 are located in the same plane. This increases the diversity of the flow path switching module 100 structure, simplifies the structure of the flow path switching module 100, reduces the space occupied by the flow path switching module 100, and ensures that when the first connection port 21, the second connection port 22, the third connection port 23, and the fourth connection port 24 of the flow path switching module 100 are welded to the pipeline, it is convenient to immerse the end of the flow path switching module 100 away from the connection side in water, which can better cool down the flow path switching module 100, improve the cooling effect of the flow path switching module 100, reduce the problem of functional failure of the flow path switching module 100 due to welding overheating, and avoid the need to wrap the flow path switching module 100 with a wet cloth, shortening the working time.

[0046] In some embodiments of this utility model, such as Figures 1-4 As shown, the first control valve 11 and the second control valve 12 are connected by the first connecting pipe 31, and the first connection port 21 is provided on the first connecting pipe 31, thereby facilitating the connection between the first control valve 11 and the second control valve 12.

[0047] Optionally, the first connecting pipe 31 is a Y-shaped pipe with three ports. Two of the three ports are connected to one end of the first control valve 11 and one end of the second control valve 12, and the remaining port is formed as the first connecting port 21.

[0048] In some embodiments of this utility model, such as Figures 1-4 As shown, the second control valve 12 and the third control valve 13 are connected by the second connecting pipe 32, and the second connecting port 22 is provided on the first connecting pipe 31, thereby facilitating the connection between the second control valve 12 and the third control valve 13.

[0049] Optionally, the second connecting pipe 32 is a Y-shaped pipe with three ports. Two of the three ports are connected to the other end of the second control valve 12 and one end of the third control valve 13, and the remaining port is formed as the second connecting port 22.

[0050] In some embodiments of this utility model, such as Figures 1-4 As shown, the third control valve 13 and the fourth control valve 14 are connected by the third connecting pipe 33, and the third connecting port 23 is provided on the third connecting pipe 33, thereby facilitating the connection between the third control valve 13 and the fourth control valve 14.

[0051] Optionally, the third connecting pipe 33 is a Y-shaped pipe with three ports. Two of the three ports are connected to the other end of the third control valve 13 and one end of the fourth control valve 14, and the remaining port is formed as the third connecting port 23.

[0052] In some embodiments of this utility model, such as Figures 1-4 As shown, the first control valve 11 and the fourth control valve 14 are connected by a fourth connecting pipe 34, and the fourth connecting port 24 is provided on the fourth connecting pipe 34, thereby facilitating the connection between the first control valve 11 and the fourth control valve 14.

[0053] Optionally, the fourth connecting pipe 34 is a Y-shaped pipe with three ports. Two of the three ports are connected to the other end of the first control valve 11 and the other end of the fourth control valve 14, and the remaining port is formed as the fourth connecting port 24.

[0054] In some embodiments of this utility model, at least one of the first control valve 11, the second control valve 12, the third control valve 13, and the fourth control valve 14 extends in a straight line. By bending the first connecting pipe 31, the second connecting pipe 32, the third connecting pipe 33, or the fourth connecting pipe 34, the first connecting port 21, the second connecting port 22, the third connecting port 23, and the fourth connecting port 24 are all located on the connection side. This allows the flow path switching module 100 to be easily immersed in water when its first connecting port 21, the second connecting port 22, the third connecting port 23, and the fourth connecting port 24 are welded to the pipeline. This facilitates better cooling of the flow path switching module 100, improves the cooling effect, reduces the problem of functional failure of the flow path switching module 100 due to overheating during welding, and avoids the need to wrap the flow path switching module 100 with a wet cloth, thus shortening the working time.

[0055] In some embodiments of this invention, the first control valve 11, the second control valve 12, the third control valve 13, and the fourth control valve 14 are one-way valves. Therefore, while achieving flow path switching, no control logic program or electric control is required, making operation convenient and energy-saving.

[0056] For example, in a specific example, the first control valve 11, the second control valve 12, the third control valve 13, and the fourth control valve 14 are one-way valves. The first control valve 11 only allows refrigerant to flow from the second connection port 22 to the first connection port 21, the second control valve 12 only allows refrigerant to flow from the third connection port 23 to the second connection port 22, the third control valve 13 only allows refrigerant to flow from the third connection port 23 to the fourth connection port 24, and the fourth control valve 14 only allows refrigerant to flow from the fourth connection port 24 to the first connection port 21.

[0059] According to the air conditioning system of this utility model embodiment, by setting the above-mentioned flow path switching module 100, not only can the flow path be switched, but also the first connection port 21, the second connection port 22, the third connection port 23 and the fourth connection port 24 are all located on the connection side. When the first connection port 21, the second connection port 22, the third connection port 23 and the fourth connection port 24 of the flow path switching module 100 are welded to the pipeline, it is convenient to immerse the end of the flow path switching module 100 away from the connection side in water, which can better cool down the flow path switching module 100, improve the cooling effect of the flow path switching module 100, reduce the problem of the flow path switching module 100 malfunctioning due to welding overheating, and at the same time avoid wrapping the flow path switching module 100 with a wet cloth, shortening the working time.

The compressor has an exhaust port and a return port. The four-way valve has a first port, a second port, a third port, and a fourth port. The first port is connected to one of the second and fourth ports, and the third port is connected to the other of the second and fourth ports. The exhaust port is connected to the first port, and the return port is connected to the third port. One end of the indoor heat exchanger is connected to the second port, and one end of the outdoor heat exchanger is connected to the fourth port. A second connection port 22 is connected to the other end of the indoor heat exchanger, and a fourth connection port 24 is connected to the other end of the outdoor heat exchanger. The first connection port 21 and the third connection port 23 are connected. The throttling device is located between the first connection port 21 and the third connection port 23. Additionally, a modular radiator for cooling the electrical control box may be provided between the first connection port 21 and the third connection port 23, and the throttling device is located between the modular radiator and the third connection port 23.

[0061] During the actual operation of the air conditioning system, when the system is in cooling mode, the compressor compresses the refrigerant into a high-temperature, high-pressure gas. The high-pressure gaseous refrigerant flows to the outdoor heat exchanger through the compressor's exhaust port, the first port of the four-way valve, and the fourth port. The outdoor heat exchanger exchanges heat with the external environment, condensing and dissipating heat. The refrigerant flows within the outdoor heat exchanger and releases heat to the external environment, thus changing from a gaseous state to a liquid state. Then, the high-pressure liquid refrigerant flowing out of the outdoor heat exchanger enters the flow path switching module 100 through the fourth connection port 24. At this time, the fourth control valve 14 controls the connection between the first connection port 21 and the fourth connection port 24, allowing the refrigerant to flow from the fourth connection port 24 to the first connection port 21. The refrigerant flows from the first connection port 21 through the module radiator and exchanges heat with the electrical control box, and then flows to the throttling device. The throttling device can reduce the pressure of the refrigerant, and then the low-pressure liquid refrigerant returns to the flow path switching module 100 through the third connection port 23.

[0062] At this time, the second control valve 12 controls the connection between the second connection port 22 and the third connection port 23, the first control valve 11 controls the disconnection between the first connection port 21 and the second connection port 22, and the fourth connection port 24 controls the disconnection between the third connection port 23 and the fourth connection port 24. Thus, the refrigerant flows from the third connection port 23 through the second control valve 12 and then out of the second connection port 22 into the flow path switching module 100 and flows to the indoor heat exchanger. The indoor heat exchanger absorbs heat, and the refrigerant vaporizes inside, changing from a liquid to a gaseous state, thereby carrying away the heat from the airflow flowing across the surface of the indoor heat exchanger. The low-temperature airflow is then delivered into the room by the indoor unit of the air conditioner to achieve the purpose of cooling. Simultaneously, the low-pressure gaseous refrigerant flows to the second port of the four-way valve and then from the third port to the return port to return to the compressor for compression again, thus forming a refrigerant cycle and achieving the cooling effect of the air conditioning system.

[0063] Similarly, when the air conditioning system is in heating mode, the compressor compresses the refrigerant into a high-temperature, high-pressure gas. The high-pressure gaseous refrigerant flows through the compressor's exhaust port, the first port and the second port of the four-way valve to the indoor heat exchanger. The indoor heat exchanger exchanges heat with the airflow flowing across its surface. The airflow absorbs heat, the refrigerant condenses and dissipates heat, and the high-temperature airflow is delivered into the room by the indoor unit to achieve the purpose of heating. The refrigerant flows within the indoor heat exchanger and releases heat into the indoor environment, thus changing from a gaseous state to a liquid state. Then, the high-pressure liquid refrigerant flowing out of the indoor heat exchanger enters the flow path switching module 100 through the second connection port 22. At this time, the first control valve 11 controls the first connection port 21 to connect with the second connection port 22, so that the refrigerant flows from the second connection port 22 to the first connection port 21. The refrigerant flows from the first connection port 21 through the module heat exchanger and the electrical control box, and then flows to the throttling device. The throttling device can play a throttling role and reduce the pressure of the refrigerant. Subsequently, the low-pressure liquid refrigerant returns to the flow path switching module 100 from the third connection port 23.

[0064] At this time, the third control valve 13 controls the connection between the third connection port 23 and the fourth connection port 24, the second control valve 12 controls the disconnection between the second connection port 22 and the third connection port 23, and the fourth connection port 24 controls the disconnection between the third connection port 23 and the fourth connection port 24. Thus, the refrigerant flows from the third connection port 23 through the third control valve 13 and out of the flow path switching module 100 via the fourth connection port 24, flowing towards the outdoor heat exchanger. The outdoor heat exchanger absorbs heat. The refrigerant is heated and vaporized within the outdoor heat exchanger, changing from a liquid to a gaseous state, thereby carrying away the heat flowing through the outdoor environment. The low-pressure gaseous refrigerant flows to the fourth port of the four-way valve and then from the third port to the return port to return to the compressor for further compression, thus forming a refrigerant cycle and achieving the heating effect of the air conditioning system.

[0065] The following describes an air conditioner according to an embodiment of the present invention.

[0066] The air conditioner according to an embodiment of the present invention includes the air conditioning system described above.

[0067] According to the air conditioner of this utility model embodiment, by setting the above-mentioned air conditioning system, the first connection port 21, the second connection port 22, the third connection port 23, and the fourth connection port 24 are all located on the connection side. When the first connection port 21, the second connection port 22, the third connection port 23, and the fourth connection port 24 of the flow path switching module 100 are welded to the pipeline, it is convenient to immerse the end of the flow path switching module 100 away from the connection side in water. This can better cool down the flow path switching module 100, improve the cooling effect of the flow path switching module 100, reduce the problem of the flow path switching module 100 failing due to welding overheating, and at the same time avoid wrapping the flow path switching module 100 with a wet cloth, shortening the working time.
