[0040] The flow path switching module 100 according to the embodiment of the utility model is described below with reference to the drawings.
[0041] As shown in the figure, Figures 1-3 The flow path switching module 100 according to the embodiment of the utility model includes a module body 1, a sliding block 21, a first control valve 22 and a second control valve 23.
[0042] Specifically, as shown in the figure, Figure 1 The module body 1 has a flow channel 11 and a first interface 12, a second interface 13, a third interface 14 and a fourth interface 15 communicated with the flow channel 11, the sliding block 21 is movably arranged in the flow channel 11, used for controlling the on-off between the first interface 12 and the second interface 13 and the on-off between the first interface 12 and the fourth interface 15;The first control valve 22 is arranged in the flow channel 11 and located between the second interface 13 and the third interface 14, used for controlling the on-off between the third interface 14 and the second interface 13 and throttling;The second control valve 23 is arranged in the flow channel 11 and located between the third interface 14 and the fourth interface 15, used for controlling the on-off between the third interface 14 and the fourth interface 15 and throttling.
[0043] It can be understood that, as Figure 2As shown, the flow path switching module 100 is applied to an air conditioning system 200, which further comprises a compressor 3, a four-way valve 4, an indoor heat exchanger 5, an outdoor heat exchanger 6 and a refrigerant loop 7. The compressor 3 has a discharge port 31 and a return port 32, the four-way valve 4 has a first port 41, a second port 42, a third port 43 and a fourth port 44, the first port 41 communicates with one of the second port 42 and the fourth port 44, the third port 43 communicates with the other one of the second port 42 and the fourth port 44, the discharge port 31 communicates with the first port 41, the return port 32 communicates with the third port 43, one end of the indoor heat exchanger 5 communicates with the second port 42, one end of the outdoor heat exchanger 6 communicates with the fourth port 44, the second interface 13 communicates with the other end of the indoor heat exchanger 5, the fourth interface 15 communicates with the other end of the outdoor heat exchanger 6, and the refrigerant loop 7 is connected between the first interface 12 and the third interface 14.
[0044] The refrigerant loop 7 abuts against an electric control component such as an electric control board for controlling the compressor 3 and other components, so as to cool the electric control component. In this way, the temperature of the electric control component can be effectively reduced, so that the electric control component can effectively dissipate heat, thereby avoiding overheating caused by failure, ensuring the performance and normal operation of the electric control component, improving the working efficiency of the electric control component and prolonging the service life of the electric control component.
[0045] In the specific operation process of the air conditioning system 200, as shown by the solid arrows in Figure 2 When the air conditioning system 200 is in a refrigeration state, the compressor 3 compresses the refrigerant into a high-temperature and high-pressure gas. The high-pressure gaseous refrigerant flows to the outdoor heat exchanger 6 through the discharge port 31 of the compressor 3, the first port 41 and the fourth port 44 of the four-way valve 4. The outdoor heat exchanger 6 can exchange heat with the external environment and dissipate heat. The refrigerant flows in the outdoor heat exchanger 6 and releases heat to the external environment, thereby changing from a gaseous state to a liquid state. Then, the high-pressure liquid refrigerant flowing out of the outdoor heat exchanger 6 enters the flow path switching module 100 from the fourth interface 15. At this time, the slider 21 slides in the flow channel 11 under the pressure of the refrigerant, so that the first interface 12 communicates with the fourth interface 15. The refrigerant flows from the fourth interface 15 to the first interface 12, and then flows through the refrigerant loop 7 to exchange heat with the electric control component, and then flows to the third interface 14 to return to the flow path switching module 100.
[0046] At this time, the first control valve 22 controls the second port 13 and the third port 14 to be communicated, the slider 21 controls the first port 12 and the second port 13 to be disconnected under the pressure of the refrigerant flowing from the fourth port 15 to the first port 12, the second control valve 23 controls the third port 14 and the fourth port 15 to be disconnected, and thus the refrigerant throttles and depressurizes through the first control valve 22 from the third port 14, the low-pressure liquid refrigerant flows out of the flow path switching module 100 from the second port 13 and flows to the indoor heat exchanger 5. The indoor heat exchanger 5 can play a role of absorbing heat, the refrigerant is heated and gasified in the indoor heat exchanger 5, changes from liquid state to gaseous state, and thus takes away the heat of the air current flowing through the surface of the indoor heat exchanger 5, the low-temperature air current is sent into the room by the air conditioner indoor unit to achieve the purpose of refrigeration. At the same time, the low-pressure gaseous refrigerant flows to the second port 42 of the four-way valve 4, and flows to the return air port 32 from the third port 43 to return to the compressor 3 for compression again, thereby forming a refrigerant cycle and realizing the refrigeration effect of the air conditioning system 200.
[0047] Similarly, as shown by the dotted arrow in the middle, Figure 2 When the air conditioning system 200 is in the heating state, the compressor 3 compresses the refrigerant into high-temperature and high-pressure gas, the high-pressure gaseous refrigerant flows to the indoor heat exchanger 5 through the exhaust port 31 of the compressor 3, the first port 41 and the second port 42 of the four-way valve 4. The indoor heat exchanger 5 can exchange heat with the air current flowing through the surface of the indoor heat exchanger 5, the air current absorbs heat, the refrigerant condenses and releases heat, the high-temperature air current is sent into the room by the air conditioner indoor unit to achieve the purpose of heating. The refrigerant flows in the indoor heat exchanger 5 and releases heat to the indoor environment, thereby changing from gaseous state to liquid state, and then the high-pressure liquid refrigerant flowing out of the indoor heat exchanger 5 enters the flow path switching module 100 from the second port 13. At this time, the slider 21 controls the first port 12 and the second port 13 to be communicated, the refrigerant flows from the second port 13 to the first port 12, and then flows through the refrigerant ring 7 and exchanges heat with the electronic control component, and then flows to the third port 14 to return to the flow path switching module 100.
[0048] At this time, the second control valve 23 controls the third port 14 and the fourth port 15 to be communicated, the first control valve 22 controls the second port 13 and the third port 14 to be disconnected, and the slider 21 controls the first port 12 and the fourth port 15 to be disconnected, and thus the refrigerant throttles and depressurizes through the second control valve 23 from the third port 14, the low-pressure liquid refrigerant flows out of the flow path switching module 100 from the fourth port 15 and flows to the outdoor heat exchanger 6. The outdoor heat exchanger 6 can play a role of absorbing heat, the refrigerant is heated and gasified in the outdoor heat exchanger 6, changes from liquid state to gaseous state, and thus takes away the heat of the outdoor environment, the low-pressure gaseous refrigerant flows to the fourth port 44 of the four-way valve 4, and flows to the return air port 32 from the third port 43 to return to the compressor 3 for compression again, thereby forming a refrigerant cycle and realizing the heating effect of the air conditioning system 200.
[0049] By setting the flow path switching module 100, no matter whether the air conditioning system 200 is in a refrigeration state or a heating state, the refrigerant flowing into the refrigerant loop 7 is the refrigerant condensed in the indoor heat exchanger 5 or the outdoor heat exchanger 6 and not throttled, so that the heat dissipation effect of the electric control component is ensured, and the risk of condensation in the refrigerant loop 7 can be avoided. Integrating the slider 21, the first control valve 22 and the second control valve 23 in the flow path switching module 100 can improve the integration of the flow path switching module 100, not only can the flow path switching during refrigeration or heating be realized, but also the throttling function is integrated in the flow path switching module 100, so that the slider 21, the first control valve 22 and the second control valve 23 can be connected through pipelines respectively, thereby the pipeline connection structure of the air conditioning system 200 can be simplified, the welding points between the pipelines can be reduced, so that the assembly difficulty can be reduced and the assembly efficiency can be improved, and then the cost can be reduced.
[0050] According to the flow path switching module 100 of the embodiment of the utility model, by setting the movable slider 21 in the flow channel 11, and integrating the first control valve 22 and the second control valve 23 with throttling function in the flow path switching module 100, when the flow path switching module 100 is applied to the air conditioning system 200, the flow path switching during refrigeration or heating can be realized, so that the refrigerant flowing into the refrigerant loop 7 is the refrigerant condensed and throttled, thereby the heat dissipation effect of the refrigerant loop 7 on the electric control component can be ensured, and the risk of condensation in the refrigerant loop 7 can be avoided, and the throttling of the refrigerant can also be realized, so that the refrigeration or heating cycle of the air conditioning system 200 can be ensured. The pipeline connection structure of the air conditioning system 200 can also be simplified, the welding points between the pipelines can be reduced, so that the assembly difficulty can be reduced and the assembly efficiency can be improved, and then the cost can be reduced.

In this way, the first interface 12, the second interface 13, the third interface 14 and the fourth interface 15 can be easily machined on the module body 1, and the first interface 12, the second interface 13, the third interface 14 and the fourth interface 15 are respectively located at different sides of the module body 1, so that the pipelines of the air conditioning system 200 can be easily connected, and mutual interference can be avoided.
[0052] In some embodiments of the utility model, as shown in Figure 1 and Figure 2As shown, two of the first interface 12, the second interface 13, the third interface 14 and the fourth interface 15 are towards the same side of the module body 1; or, three of the first interface 12, the second interface 13, the third interface 14 and the fourth interface 15 are towards the same side of the module body 1; or, all of the first interface 12, the second interface 13, the third interface 14 and the fourth interface 15 are towards the same side of the module body 1. In this way, the flow path switching module 100 is distributed at the multiple interfaces on the same side, which is connected with the pipeline in the air conditioning system 200, so that the assembly difficulty can be reduced, the flexibility and applicability of the flow path switching module 100 can be improved, and then the assembly efficiency can be improved.

[0054] Further, the sliding block 21, the first control valve 22 and the second control valve 23 are sequentially and spacedly arranged in the ring-shaped flow passage 11 and respectively located between the second interface 13 and the fourth interface 15, between the second interface 13 and the third interface 14 and between the third interface 14 and the fourth interface 15, so that the structure arrangement is reasonable, the sliding block 21, the first control valve 22 and the second control valve 23 can be controlled to control the on-off of the flow path, thereby the flow path switching during refrigeration or heating can be realized. Without the need for additionally arranging the pipeline to connect the sliding block 21, the first control valve 22 and the second control valve 23, the pipeline connection structure can be further simplified and the cost can be reduced.
[0055] In some embodiments of the utility model, as shown in Figures 1-3 As shown, the module body 1 is generally in a ring shape, and the flow passage 11 extends in a ring shape along the circumferential direction of the module body 1.

[0061] In some embodiments of the utility model, as shown in Figures 1-3 As shown, when the first interface 12 communicates with the second interface 13, the first interface 12 is disconnected from the fourth interface 15; when the first interface 12 communicates with the fourth interface 15, the first interface 12 is disconnected from the second interface 13. When the slider 21 slides in the flow channel 11, when the first interface 12 is opened, only one of the first interface 12, the second interface 13 and the fourth interface 15 is allowed to communicate. When the refrigerant flows from the fourth interface 15 to the first interface 12, the second interface 13 is disconnected from the first interface 12, and the refrigerant entering from the third interface 14 can only flow to the second interface 13 through the first control valve 22 but not to the first interface 12. Similarly, when the refrigerant flows from the second interface 13 to the first interface 12, the fourth interface 15 is disconnected from the first interface 12, and the refrigerant entering from the third interface 14 can only flow to the fourth interface 15 through the second control valve 23 but not to the first interface 12. In this way, the refrigerant circulation and flow path switching of the air conditioning system 200 in the refrigeration or heating state can be ensured, and the structural design is reasonable.
[0062] In some embodiments of the utility model, as shown in Figures 1-3 As shown, when the first interface 12 communicates with the second interface 13, the slider 21 is located on one side of the first interface 12 close to the fourth interface 15; when the first interface 12 communicates with the fourth interface 15, the slider 21 is located on one side of the first interface 12 close to the second interface 13.
[0063] When the refrigerant flows into the flow path switching module 100 from the second interface 13, the sliding block 21 slides in the flow channel 11 under the pressure of the refrigerant towards the fourth interface 15, when the sliding block 21 slides to the side of the first interface 12 close to the fourth interface 15, the first interface 12 communicates with the second interface 13, the refrigerant can flow from the second interface 13 to the first interface 12 and enter the refrigerant ring 7. At the same time, the refrigerant flowing out of the refrigerant ring 7 enters the flow path switching module 100 from the third interface 14, at this time, the high-pressure refrigerant flows from the second interface 13 to the first interface 12. The first control valve 22 controls the second interface 13 and the third interface 14 to be disconnected, and the sliding block 21 blocks the passage between the first interface 12 and the fourth interface 15 under the pressure of the refrigerant flowing from the second interface 13 to the first interface 12, so that the refrigerant flows from the third interface 14 to the fourth interface 15 and flows out of the flow path switching module 100.
[0064] Similarly, when the refrigerant flows into the flow path switching module 100 from the fourth interface 15, the sliding block 21 slides in the flow channel 11 under the pressure of the refrigerant towards the second interface 13, when the sliding block 21 slides to the side of the first interface 12 close to the second interface 13, the first interface 12 communicates with the fourth interface 15, the refrigerant can flow from the fourth interface 15 to the first interface 12 and enter the refrigerant ring 7. At the same time, the refrigerant flowing out of the refrigerant ring 7 enters the flow path switching module 100 from the third interface 14, at this time, the high-pressure refrigerant flows from the fourth interface 15 to the first interface 12. The second control valve 23 controls the fourth interface 15 and the third interface 14 to be disconnected, and the sliding block 21 blocks the passage between the first interface 12 and the second interface 13 under the pressure of the refrigerant flowing from the fourth interface 15 to the first interface 12, so that the refrigerant flows from the third interface 14 to the second interface 13 and flows out of the flow path switching module 100.
[0065] The sliding block 21 can automatically adjust and control the connection and disconnection between the first interface 12 and the second interface 13 and the connection and disconnection between the first interface 12 and the fourth interface 15 according to the pressure of the refrigerant flowing in the flow channel 11, so as to realize automatic flow guiding and flow path switching, without the need for additionally arranging other control devices, and the structure is simple, easy to realize and low in cost.
[0066] In some embodiments of the utility model, as shown in Figures 1-3 As shown in the drawings, the inner circumferential wall of the flow channel 11 is provided with a first limiting piece 24 and a second limiting piece 25, the first limiting piece 24 is arranged between the first interface 12 and the second interface 13, the second limiting piece 25 is arranged between the first interface 12 and the fourth interface 15, and the sliding block 21 is movably arranged between the first limiting piece 24 and the second limiting piece 25. When the sliding block 21 abuts against the first limiting piece 24, the first interface 12 communicates with the fourth interface 15, and the first interface 12 is disconnected from the second interface 13; when the sliding block 21 abuts against the second limiting piece 25, the first interface 12 communicates with the second interface 13, and the first interface 12 is disconnected from the fourth interface 15.
[0067] The first limiting piece 24 and the second limiting piece 25 can limit the sliding block 21, so that the sliding block 21 can only move in the flow channel 11 between the first limiting piece 24 and the second limiting piece 25. When the refrigerant flows into the flow path switching module 100 from the second interface 13, the sliding block 21 slides in the flow channel 11 under the pressure of the refrigerant towards the fourth interface 15, when the sliding block 21 abuts against the second limiting piece 25, the first interface 12 is communicated with the second interface 13, the first interface 12 and the fourth interface 15 are disconnected, and meanwhile, the sliding block 21 can be prevented from sliding to the fourth interface 15 to block the fourth interface 15.
[0068] Similarly, when the refrigerant flows into the flow path switching module 100 from the fourth interface 15, the sliding block 21 slides in the flow channel 11 under the pressure of the refrigerant towards the second interface 13, when the sliding block 21 abuts against the first limiting piece 24, the first interface 12 is communicated with the fourth interface 15, the first interface 12 and the second interface 13 are disconnected, and meanwhile, the sliding block 21 can be prevented from sliding to the second interface 13 to block the second interface 13. The automatic flow guiding and flow path switching of the sliding block 21 can be realized, and the sliding block 21 can be limited in a reasonable range of the flow channel 11, so that the sliding block 21 can be prevented from blocking the second interface 13 or the fourth interface 15, thereby the stability of the refrigerant circulation in the air conditioning system 200 can be improved.
[0069] In some embodiments of the present application, as shown in Figures 1-3 The first control valve 22 is a one-way throttle valve, and the first control valve 22 only allows the refrigerant to flow from the third interface 14 to the second interface 13. When the air conditioning system 200 is in a refrigeration state, the refrigerant flows through the refrigerant ring 7 to exchange heat with the electronic control component, and then flows to the third interface 14 to return to the flow path switching module 100, and the one-way throttle valve is used to realize throttling and automatic flow to the second interface 13 to flow to the indoor heat exchanger 5. The second control valve 23 is automatically opened or closed or cut off by the pressure difference of the refrigerant on both sides of the one-way throttle valve, so that the automatic flow guiding of the refrigerant by the second control valve 23 can be realized, the structure is simple, and other control structures do not need to be set, and the air conditioning system 200 is not easily affected by power failure. At the same time, the one-way throttle valve can also realize the throttling and pressure reduction of the refrigerant, the integration of the second control valve 23 can be improved, thereby the assembly efficiency can be improved and the cost can be reduced.
[0070] In some embodiments of the present application, as shown in Figure 4As shown, the second control valve 23 is a one-way throttle valve, and the second control valve 23 only allows the refrigerant to flow from the third interface 14 to the fourth interface 15. Therefore, when the air conditioning system 200 is in the heating state, the refrigerant flows through the refrigerant ring 7 and exchanges heat with the electric control component, and then flows to the third interface 14 back to the flow path switching module 100, and is throttled through the one-way throttle valve and automatically flows to the fourth interface 15 to flow to the outdoor heat exchanger 6. The third control valve is automatically opened or cut off by the pressure difference of the refrigerant on both sides of the one-way throttle valve, so that the automatic flow guiding of the refrigerant by the third control valve can be realized, the structure is simple, other control structures do not need to be arranged, and the air conditioning system 200 is not easy to be affected by power failure and the like. At the same time, the refrigerant can be throttled and depressurized, the integration of the third control valve can be improved, and therefore the assembly efficiency can be improved and the cost can be reduced.

[0073] Specifically, as shown, The compressor 3 has an exhaust port 31 and a return port 32; the four-way valve 4 has a first port 41, a second port 42, a third port 43 and a fourth port 44, the first port 41 communicates with one of the second port 42 and the fourth port 44, the third port 43 communicates with the other one of the second port 42 and the fourth port 44, the exhaust port 31 communicates with the first port 41, and the return port 32 communicates with the third port 43; one end of the indoor heat exchanger 5 communicates with the second port 42; one end of the outdoor heat exchanger 6 communicates with the fourth port 44; the second interface 13 communicates with the other end of the indoor heat exchanger 5, the fourth interface 15 communicates with the other end of the outdoor heat exchanger 6, and the refrigerant ring 7 is connected between the first interface 12 and the third interface 14.
[0074] The air conditioning system 200 according to the embodiment of the present application can realize flow path switching when refrigerating or heating by arranging the movable slider 21 in the flow channel 11 and integrating the first control valve 22 and the second control valve 23 with throttling function in the flow path switching module 100. When the flow path switching module 100 is applied to the air conditioning system 200, the refrigerant flowing into the refrigerant ring 7 is condensed and throttled, so as to ensure the heat dissipation effect of the refrigerant ring 7 on the electric control component, avoid the risk of condensation in the refrigerant ring 7, and realize the throttling of the refrigerant to ensure the refrigeration or heating cycle of the air conditioning system 200. The pipe connection structure of the air conditioning system 200 can be simplified, the welding points between the pipes can be reduced, the assembly difficulty can be reduced and the assembly efficiency can be improved, and therefore the cost can be reduced.
