[0033] A four-way reversing valve (hereinafter referred to as a four-way valve) is a common component in refrigeration equipment, especially air conditioners. Its function is to switch the flow of refrigerant when the air conditioner switches between cooling and heating functions, thereby changing the air conditioner's cooling and heating capabilities. The four-way valve switches the refrigerant flow by pushing a rubber slider through refrigerant pressure. However, the rubber expands and contracts with temperature changes, which can easily cause the slider to stick, resulting in low long-term stability of the four-way reversing valve.

[0034] For this, please refer to Figure 1 This application provides a multi-way valve 100, which includes a valve body 10, a slider 20, and a drive structure 30. The valve body 10 has a valve cavity 11 formed therein, and the valve body 10 has a plurality of communication ports communicating with the valve cavity 11. The slider 20 is disposed in the valve cavity 11, and the slider 20 has a conduction cavity 21 for conducting several of the plurality of communication ports. The slider 20 can slide between the plurality of communication ports to switch the communication port conducted by the conduction cavity 21 during the sliding process of the slider 20. The drive structure 30 is used to drive the slider 20 to be suspended in the valve cavity 11 during the sliding process of the slider 20.

[0035] It should be noted that the specific implementation of the multi-way valve 100 is not limited; it can be a three-way valve, a four-way valve, a five-way valve, etc. The specific number of the multiple connecting ports that the guiding cavity 21 is used to connect is not limited; it can be two, three, four, etc., and is not limited here. All of the multiple connecting ports can be within the active stroke of the slider 20, or only a portion can be within the active stroke of the slider 20; this is not limited here.

[0036] The specific application of the multi-way valve 100 is not limited; it can be used in air conditioners, refrigerators, etc., and is not limited here. The specific implementation of the drive structure 30 is not limited; it can be in the form of an air pump, a magnetic drive, a motor drive, etc., and is not limited here.

[0037] The method of communication between the conductive cavity 21 and the multiple communication ports is not limited. It can be that a conductive port connecting the conductive cavity 21 is provided on the slider 20, so that when the conductive port and the communication port are aligned, the conductive cavity 21 and the communication port are connected. Alternatively, the conductive cavity 21 can be set to be open at one end, so that several communication ports can be directly connected through the open end of the conductive cavity 21, etc., without limitation.

[0038] The sliding mechanism of the slider 20 is not limited; it can be driven manually or by an additional driving device 40, etc., and is not limited here.

[0039] In the corresponding embodiment, by setting the driving structure 30, the slider 20 can be driven to be suspended in the valve cavity 11, which effectively solves the jamming phenomenon caused by the adhesion between the slider 20 and the valve body 10. Furthermore, during the sliding process, the slider 20 is suspended in the valve cavity 11, which can also effectively reduce the friction force on the slider 20 during the sliding process, thereby improving the smoothness of the slider 20's sliding and better switching the connection port of the conducting cavity 21.

[0040] Furthermore, in some embodiments, the drive structure 30 includes a magnetic movable part 31 and a magnetic drive part 32. The magnetic movable part 31 is fixedly disposed on the slider 20; the magnetic drive part 32 is disposed on the valve body 10 and is used to drive the magnetic movable part 31 away during the sliding of the slider 20, so that the slider 20 is suspended in the valve cavity 11.

[0041] Specifically, the specific implementation of the magnetic active part 31 and the magnetic drive part 32 is not limited. It can be a combination of permanent magnet and electromagnet, or a combination of two electromagnets, etc., and is not limited here.

[0042] During the sliding of the slider 20, the magnetic active part 31 is driven away so that the slider 20 is suspended in the valve cavity 11. Specifically, when one of the magnetic active part 31 and the magnetic drive part 32 is configured as an electromagnet or an electromagnetic coil, it generates a magnetic field that repels the other, thereby suspending the slider 20 in the valve cavity 11.

[0043] In the scheme of this embodiment, by setting the driving structure 30 as the magnetic moving part 31 and the magnetic driving part 32, the slider 20 can be magnetically levitated. Compared with other forms of driving structure 30, it is not necessary to set too many structures in the valve cavity 11, thereby improving the stability of the structure.

[0044] In some embodiments, the magnetically active part 31 is a permanent magnet; and / or, the magnetically driven part 32 is an electromagnetic coil.

[0045] In the solution of this embodiment, by setting the magnetic active part 31 as a permanent magnet, it is not necessary to conduct electricity to the slider 20, but only to conduct electricity to the magnetic drive part 32, which reduces the difficulty of wiring.

[0046] Specifically, when the slider 20 moves, the magnetic drive unit 32 is made conductive, and then the electromagnetic coil generates a magnetic field, thereby driving the magnetic movable part 31 to move away from the magnetic drive unit 32, allowing the slider 20 to suspend in the valve cavity 11. After the slider 20 has switched, the electromagnetic coil can be de-energized, allowing the slider 20 to fall under its own gravity, isolating the conductive cavity 21 from other parts in the valve cavity 11. Alternatively, the electromagnetic coil can generate a reverse magnetic field, thereby attracting the magnetic movable part 31 to the valve body 10, etc., without limitation.

[0047] In some embodiments, the conductive cavity 21 is open at one end, and the magnetic movable part 31 is disposed at the open end of the conductive cavity 21 of the slider 20.

[0048] In the scheme of this embodiment, since the magnetic active part 31 is disposed at the opening end of the conductive cavity 21 of the slider 20, when the slider 20 is not required to move, the electromagnetic coil generates a reverse magnetic field, which enables the magnetic active part 31 and the magnetic drive part 32 to be tightly combined, preventing the refrigerant in the conductive cavity 21 from leaking out and improving the airtightness of the conductive cavity 21.

[0049] Since the valve cavity 11 is often in a high-pressure environment, directly installing a drive device 40 inside the valve cavity 11 to drive the sliding of the slider 20 is difficult, costly, and unstable. Therefore, in some embodiments, the valve body 10 includes a housing 12 and a valve core 13, with a receiving cavity formed inside the housing 12; the valve core 13 is movably disposed within the receiving cavity and defines the valve cavity 11 within the receiving cavity, and the valve core 13 is connected to the slider 20 so that the slider 20 moves when the valve core 13 moves.

[0050] In the scheme of this embodiment, by setting the valve body 10 as a housing 12 and a valve core 13, and the valve core 13 is connected to the slider 20, the slider 20 can be driven to move together when the valve core 13 moves. Furthermore, it is not necessary to set a drive device 40 in the valve cavity 11 to directly drive the slider 20 to slide, thereby improving the long-term stability of the multi-way valve 100.

[0051] The valve core 13 and the slider 20 can be connected by a rigid connector 14, or by an elastic connector 14, or by making one half of the connector 14 rigid and the other half elastic, etc., without limitation here.

[0052] In some embodiments, the connecting member 14 between the valve core 13 and the slider 20 is elastically deformable. With this configuration, the slider 20 can float more smoothly under the drive of the drive structure 30, avoiding the obstruction of the slider 20 by the purely rigid connecting member 14.

[0053] In some embodiments, four communication ports are provided, including a first communication port 15 for connecting to the compressor exhaust port, a second communication port 16 for connecting to the indoor heat exchanger, a third communication port 17 for connecting to the compressor intake port, and a fourth communication port 18 for connecting to the outdoor heat exchanger. The first communication port 15 is located outside the conductive cavity 21, and the second communication port 16, the third communication port 17, and the fourth communication port 18 are located on the active stroke of the slider 20, so that when the slider 20 slides, the conductive cavity 21 can selectively connect the third communication port 17 to one of the second communication port 16 and the fourth communication port 18.

[0054] It should be noted that when the air conditioner is in heating mode, the connecting cavity 21 connects the third connecting port 17 and the fourth connecting port 18, thereby connecting the compressor's suction port to the outdoor heat exchanger. This allows the refrigerant flowing out of the outdoor heat exchanger to return to the compressor and be compressed. At this time, the first connecting port 15 and the second connecting port 16 are connected by the valve cavity 11, allowing the refrigerant discharged from the compressor's exhaust port to flow into the indoor heat exchanger for heat exchange. After exchanging heat with the outdoor heat exchanger, it returns to the compressor via the third connecting port 17 and the fourth connecting port 18 for compression again, completing the heating cycle.

[0055] When the air conditioner is in cooling mode, the conductive cavity 21 connects the third connecting port 17 and the second connecting port 16. At this time, the first connecting port 15 and the fourth connecting port 18 are connected by the valve cavity 11. Correspondingly, at this time, the high-pressure refrigerant discharged from the compressor's exhaust port enters the valve cavity 11 from the first connecting port 15, enters the fourth connecting port 18 through the valve cavity 11, reaches the outdoor heat exchanger to release heat, and then absorbs heat at the indoor heat exchanger. After heat absorption, it enters the conductive cavity 21 through the second connecting port 16, and then returns to the compressor's exhaust port through the third connecting port 17, where it is compressed again by the compressor to complete the refrigeration cycle.

[0056] During the switching between the cooling mode and the heating mode, the slider 20 slides to switch the connection port of the connecting cavity 21. For example, in the heating mode, the connecting cavity 21 is located above the third connecting port 17 and the fourth connecting port 18, thereby connecting the third connecting port 17 and the fourth connecting port 18. At this time, it is necessary to switch to the cooling mode. The slider 20 slides, allowing the connecting cavity 21 to connect the third connecting port 17 and the second connecting port 16. That is, the connecting cavity 21 needs to slide from its original position above the fourth connecting port 18 to its position above the second connecting port 16. When this sliding begins, the driving structure 30 can drive the slider 20 to be suspended in the valve cavity 11, effectively solving the jamming phenomenon caused by the adhesion between the slider 20 and the valve body 10. Furthermore, during the sliding process, the slider 20 is suspended in the valve cavity 11, which can also effectively reduce the friction force on the slider 20 during the sliding process, making the switching accuracy of the air conditioner between cooling and heating more accurate.

[0057] It should be noted that the first communication port 15 is located outside the conduction cavity 21. It can be located inside the valve cavity 11 and outside the conduction cavity 21 at any position, such as the side of the slider 20, the bottom of the slider 20, the top of the slider 20, etc., and is not limited here.

[0058] In some embodiments, the first connecting port 15 is located at the top of the slider 20, and the second connecting port 16, the third connecting port 17, and the fourth connecting port 18 are located at the bottom of the slider 20. With this configuration, since the first connecting port 15 is connected to the exhaust port of the compressor, it will inject high-pressure refrigerant into the valve chamber 11. Under the pressure of the refrigerant, the slider 20 can be firmly pressed against the housing 12, thereby improving the airtightness of the connecting cavity 21 and preventing refrigerant leakage in the connecting cavity 21.

[0059] The method of driving the valve core 13 to move is not limited; it can be driven by a cylinder or a pneumatic pump, etc., and is not limited here. In some embodiments, the valve core 13 divides the receiving cavity to form the valve cavity 11 and two pressure chambers 19. The multi-way valve 100 also includes a driving device 40, which is connected to the first communication port 15 and the two pressure chambers 19, and can selectively connect the first communication port 15 to one of the two pressure chambers 19 to drive the slider 20 to move by the exhaust pressure of the compressor.

[0060] In the scheme of this embodiment, the driving device 40 is connected to the first communication port 15 and the two pressure chambers 19, and can selectively connect the first communication port 15 to one of the two pressure chambers 19. When the first communication port 15 is connected to one of the pressure chambers 19, the high-pressure refrigerant discharged from the compressor's exhaust port can be injected into the pressure chamber 19, forming a high-pressure environment in the pressure chamber 19. This causes the valve core 13 to move towards the other pressure chamber 19 under the action of air pressure, thereby driving the valve core 13. The entire driving process cleverly utilizes the compressor's exhaust pressure to drive the movement of the valve core 13, without the need for additional power sources such as air pumps, motors, or magnetic actuators, thus saving costs.

[0061] Specifically, the valve core 13 is not limited in its specific implementation form. It can be in the form of a housing 12, so that the inner cavity of the housing 12 forms the valve cavity 11. It can also be in the form of two partitions. By setting two partitions, the receiving cavity can be divided to form the valve cavity 11 and the two pressure chambers 19, etc. There is no limitation here.

[0062] In some embodiments, the drive device 40 is also connected to the third communication port 17 so that when the first communication port 15 is selectively connected to one of the two pressure chambers 19, the third communication port 17 is connected to the other pressure chamber 19.

[0063] In the scheme of this embodiment, when the first connecting port 15 is selectively connected to one of the two pressure chambers 19, the third connecting port 17 is connected to the other pressure chamber 19. This configuration allows the refrigerant in the other pressure chamber 19 to be recycled and reused, which improves the stability of the valve core 13 during operation and increases the utilization rate of the refrigerant.

[0064] Specifically, the driving device 40 includes a pilot valve body 41 and an electromagnetic actuator 42. The pilot valve body 41 has a pilot valve cavity 411, which is connected to the first communication port 15, the third communication port 17, and the two pressure chambers 19 through a pilot capillary tube 43. A pilot block 44 is provided in the pilot valve cavity 411, and a pilot cavity 441 is provided in the pilot block 44. When the first communication port 15 is connected to one of the two pressure chambers 19 through the pilot valve cavity 411, the pilot cavity 441 connects the third communication port 17 to the other pressure chamber 19. The electromagnetic actuator 42 includes an electromagnetic coil and an elastic element 45. The electromagnetic coil is used to drive the pilot block 44 away from the movement, and the elastic element 45 is used to drive the pilot block 44 closer to the movement when the electromagnetic coil is de-energized.

[0065] by Figure 1 Taking the multi-way valve 100 as an example, when the electromagnetic coil is energized, it drives the pilot block 44 to move to the left, thereby connecting the third connecting port 17 and the left pressure chamber 19 through the pilot chamber 441. This allows the refrigerant in the left pressure chamber 19 to flow into the compressor's suction port and participate in the refrigerant cycle again. Meanwhile, the right pressure chamber 19 is connected by the pilot valve chamber 411, allowing the high-temperature refrigerant discharged from the compressor's exhaust port to reach the right pressure chamber 19. At this time, the right pressure chamber 19 is in a high-pressure environment, while the left pressure chamber 19 is in a low-pressure or normal-pressure environment. The valve core 13 will move to the left, and then the connecting chamber 21 of the slider 20 will connect the third connecting port 17 and the indoor heat exchanger, thereby achieving cooling of the room.

[0066] When switching is required, the electromagnetic coil is de-energized. Then, under the action of the elastic element 45, the pilot block 44 moves to the right, thereby connecting the third connecting port 17 and the right pressure chamber 19 through the pilot chamber 441. This allows the refrigerant in the right pressure chamber 19 to flow into the compressor's suction port and participate in the refrigerant circulation again. Meanwhile, the left pressure chamber 19 and the first connecting port 15 are connected by the pilot valve chamber 411, allowing the high-temperature refrigerant discharged from the compressor's exhaust port to reach the right pressure chamber 19. At this time, the left pressure chamber 19 is in a high-pressure environment, while the right pressure chamber 19 is in a low-pressure or normal-pressure environment. The valve core 13 moves to the right, and then the connecting chamber 21 of the slider 20 connects the third connecting port 17 and the outdoor heat exchanger, thereby achieving heating in the room.

[0067] When the slider 20 moves, the magnetic drive unit 32 generates a positive magnetic field, causing the slider 20 to suspend. After the slider 20 has moved for a first preset time, such as 5 seconds, it is determined that the slider 20 has moved to a preset position. At this time, the magnetic drive unit 32 generates a reverse magnetic field, thereby firmly connecting the magnetic moving part 31 and the magnetic drive unit 32 together, preventing refrigerant leakage in the conductive cavity 21.

[0068] This utility model also proposes an air conditioner, which is equipped with a multi-way valve 100. The specific structure of the multi-way valve 100 is as described in the above embodiments. Since the multi-way valve 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application.
