DETAILED DESCRIPTION

[0054] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The description of the at least one exemplary embodiment is actually only illustrative, but not as any limitation on the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0055] In the description of the present application, it should be understood that the orientation words such as "front, back, up, down, left, right", "transverse, vertical, perpendicular, horizontal" and "top, bottom" and the like indicate the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate and imply that the indicated device or element must have a particular orientation or be constructed and operated in a particular orientation, therefore it cannot be understood as a limitation on the scope of protection of the present application; the orientation words "inner, outer" refer to the inner and outer relative to the contour of each component itself.

[0056] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0057] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0058] See also Figures 1 to 11 As shown, according to an embodiment of the present invention, a valve device is provided, which includes a valve seat 3, a first valve core 1, and a second valve core 2; a plurality of first valve ports 31 and second valve ports 32 are provided on the circumferential outer wall of the valve seat 3; the first valve core 1 is installed at one end of the valve seat 3, and the second valve core 2 is installed at the other end of the valve seat 3; the first valve core 1 and the second valve core 2 are rotatably disposed in the valve seat 3; a plurality of first conducting structures 101 are provided in the circumferential direction of the first valve core 1, and the first conducting structures 101 are used to connect at least two first valve ports 31; a plurality of second conducting structures 201 are provided in the circumferential direction of the second valve core 2, and the second conducting structures 201 are used to connect at least two second valve ports 32; the first valve core 1 and the second valve core 2 each have a plurality of rotational positions, so that the plurality of first valve ports 31 are respectively connected to different first conducting structures 101, and the plurality of second valve ports 32 are respectively connected to different second conducting structures 201.

[0059] Specifically, the first valve core 1 can be rotated alone, and the second valve core 2 can also be rotated alone. When the first valve core 1 is rotated clockwise or counterclockwise to a first rotation position, a plurality of first valve ports 31 are in communication with a plurality of first conductive structures 101 in the circumferential direction of the first valve core 1. When the first valve core 1 continues to rotate clockwise or counterclockwise by a certain angle, part or all of the first conductive structures 101 at the first rotation position are rotated to the wall surface of the valve seat 3 without valve ports, that is, part or all of the first conductive structures 101 at the first rotation position are not in communication with the first valve ports 31, but are blocked. When the first valve core 1 continues to rotate clockwise or counterclockwise by a certain angle, the first conductive structures 101 corresponding to the plurality of first valve ports 31 are still in communication. Similarly, the second valve core 2 is rotated in the same way as the first valve core 1, but the rotation angle and direction can be different from those of the first valve core 1. When the second valve core 2 is rotated clockwise or counterclockwise to a first rotation position, a plurality of second valve ports 32 are in communication with a plurality of second conductive structures 201 in the circumferential direction of the second valve core 2. When the second valve core 2 continues to rotate clockwise or counterclockwise by a certain angle, part or all of the second conductive structures 201 at the first rotation position are rotated to the wall surface of the valve seat 3 without valve ports, that is, part or all of the second conductive structures 201 at the first rotation position are not in communication with the second valve ports 32, but are blocked. When the second valve core 2 continues to rotate clockwise or counterclockwise by a certain angle, the second conductive structures 201 corresponding to the plurality of second valve ports 32 are still in communication. Since a plurality of component interfaces outside are in communication with the first valve ports 31 and the second valve ports 32, not all of the first valve ports 31 and the second valve ports 32 need to be in communication according to different operating modes of the air conditioner. By rotating the first valve core 1 and the second valve core 2 to different rotation positions, the valve ports and the conductive structures that need to be in communication with the component interfaces are in communication.

[0060] In the embodiment, one valve seat 3 is matched with two valve cores, and the two valve cores can be rotated independently, so as to flexibly control the communication state of the plurality of first valve ports 31 and second valve ports 32 and the corresponding conduction structures. According to different air conditioner operation modes, the first valve core 1 and the second valve core 2 can be rotated to different rotation positions, so that the valve ports and the conduction structures that need to be connected with the components are connected, the adaptability and flexibility of the system are improved. Compared with the switching of different pipelines using a three-way valve, a four-way valve or other combinations of water valves, the embodiment can be connected with a plurality of external components by only setting one valve device. By adjusting the position of the valve core, the need for additional valves and pipelines can be reduced, the system design is simplified, and the cost and maintenance difficulty are reduced. In addition, in the embodiment, the conduction structure provided on the valve core and the valve port on the valve seat 3 are matched, so that the flow direction of the fluid can be accurately controlled, the fluid can flow along the predetermined path, the plurality of valve ports and conduction structures can form a plurality of fluid channels at the same time, the flexibility and control ability of the system are improved, and the risk of fluid leakage can be reduced, and the sealing performance and reliability of the system are improved.

[0061] It is worth noting that the adjacent first conduction structures 101 are not connected with each other in the axial direction and the circumferential direction, and the adjacent second conduction structures 201 are not connected with each other in the axial direction and the circumferential direction. In this way, it can be ensured that the conduction structures are isolated from each other. When the valve port is aligned with the conduction structure, the valve port and the conduction structure are connected, and are not connected with the adjacent conduction structure, so as to ensure that the fluid does not flow between the conduction structures. In the embodiment, the first valve core 1 is driven by the first actuator 41, and the second valve core 2 is driven by the second actuator 42.

[0062] Referring to Figures 3 to 5 As shown in the figure, the valve device is a fourteen-way valve, the circumferential outer wall of the valve seat 3 has a first mounting surface 301 and a second mounting surface 302, the first mounting surface 301 is arrayed with nine first valve ports 31, and the second mounting surface 302 is arrayed with six second valve ports 32.

[0063] Specifically, the valve seat 3 is a hollow structure, the valve seat 3 comprises a mounting plate and an annular shell connected with each other, the outer wall surface of the mounting plate is a plane, specifically the outer wall surface of the mounting plate has a first mounting surface 301 and a second mounting surface 302, the first valve port 31 and the second valve port 32 penetrate through the mounting plate and communicate with the inner cavity of the annular shell, nine first valve ports 31 are arranged in a manner of three rows and three columns, and six second valve ports 32 are arranged in a manner of two rows and three columns. The first valve port 31 on the first mounting surface 301 cooperates with the first conducting structure 101 of the first valve core 1 to communicate between two adjacent first valve ports 31, and the second valve port 32 on the second mounting surface 302 cooperates with the second conducting structure 201 of the second valve core 2 to communicate between two adjacent second valve ports 32, so as to conduct between the components of the air conditioning system and enable the fluid to flow between the components.

[0064] In the embodiment, a total of fifteen valve ports are arranged on the mounting plate, which can meet the communication of multiple interfaces. It is worth noting that the arrangement of the valve ports on the valve seat 3 is defined based on the schematic diagram of the air conditioning system provided in the embodiment, and two valve ports for defining the electrical control outlets of the motor are defined on the mounting plate of the valve seat 3.

[0065] For reference Figures 6 to 11 As shown in the figure, the first conducting structure 101 communicates with two first valve ports 31, and the development surface of the first valve core 1 in the circumferential direction is taken as the projection surface, part of the first conducting structure 101 is arranged horizontally, and the two first valve ports 31 are arranged side by side; part of the first conducting structure 101 is arranged vertically, and the two first valve ports 31 are arranged in the same column.

[0066] Specifically, considering that the fluid usually flows from the outlet of one component to the inlet of another component in the circulation process, the first conducting structure 101 of the embodiment is arranged to communicate with two first valve ports 31, and after the two first valve ports 31 and the first conducting structure 101 are communicated, one of the first valve ports 31 serves as the outlet interface of one component, and the other first valve port 31 serves as the inlet interface of another component, so that the outlet of one component in the fluid flows into the first conducting structure 101 first and then flows into the inlet interface of another component, thereby realizing the flow-through of the fluid between the components through the valve device. Since the first valve core 1 of the embodiment is provided with a plurality of first conducting structures 101 in the circumferential direction, when the first valve core 1 is developed in the circumferential direction, the development surface is rectangular, and in the process of rotating the first valve core 1, the first conducting structure 101 can be horizontally arranged or vertically arranged, and when two adjacent first valve ports 31 are rotated to different rotating positions according to the first valve core 1, the two first valve ports 31 can be arranged side by side with one first conducting structure 101 or arranged in parallel with one first conducting structure 101, that is, even if only one first valve port 31 communicates with one conducting structure, the first valve port 31 also does not need to be connected with the interface of the external component.

[0067] In this embodiment, the first conductive structure 101, arranged horizontally and vertically, allows for flexible configuration of the fluid path as needed, enabling complex fluid control logic. It also allows for more fluid channels within a limited space, improving space utilization. Furthermore, connecting the two first valve ports 31 through the first conductive structure 101 reduces fluid resistance in the system and improves fluid flow efficiency. By optimizing the layout of the first conductive structure 101, this embodiment reduces the number of valves required, simplifies system design, lowers manufacturing and maintenance costs, ensures smooth fluid flow from the outlet of one component to the inlet of another, reduces the risk of fluid leakage, and improves system reliability.

[0068] According to the conventional connection method of external components, the two valve ports are usually interconnected. As another implementation method, the first conducting structure 101 and the second conducting structure 201 can also be connected to the conducting structure with three or four valve ports according to the fluid diversion requirements or fluid flow requirements, so as to realize the diversion of fluid or increase the flow of fluid to one of the components.

[0069] See also Figures 6 to 11 As shown, the first conductive structure 101 is a first groove, which penetrates the circumferential outer wall of the first valve core 1. One end of the first groove is connected to a first valve port 31, and the other end of the first groove is connected to a first valve port 31. A first channel is formed between the two first valve ports 31.

[0070] Specifically, the first conductive structure 101 forms a first channel by slotting on the circumferential outer wall of the first valve core 1. With the cross-section of the first valve core 1 as the projection plane, the first groove is provided with an arc-shaped chamfer to avoid dead corners. After connecting the two ends of the first groove to the first valve port 31 respectively, it is equivalent to the inlet of the first channel extending to one of the first valve ports 31 and the outlet of the first channel extending to the other first valve port 31.

[0071] In this embodiment, the first groove, combined with the two first valve ports 31, can connect the two first valve ports 31 into a channel, optimize the fluid flow path, reduce flow resistance, and thus improve the efficiency of fluid flow. Moreover, the groove can provide a better sealing effect, reduce the risk of fluid leakage, and improve the reliability of the system. The opening of the first groove can fully align with the first valve port 31, ensuring that the first valve port 31 can more easily connect with the first conductive structure 101 during the rotation of the first valve core 1.

[0072] See also Figures 6 to 11As shown, along the axial direction of the first valve core 1, a plurality of first blind holes 102 are formed on the first valve core 1, and the first blind holes 102 have a blocking surface, which is adjacent to the first through structure 101, and the blocking surface is used to block the first valve port 31.

[0073] Specifically, since the number of the first valve ports 31 arranged on the first mounting surface 301 is large, that is, the combination form of the first through structure 101 is more and the communication mode of the first valve port 31 and the first through structure 101 is more, the embodiment forms a plurality of first blind holes 102 on the first valve core 1, the first blind holes 102 are formed from the axial direction of the first valve core 1 to the inside of the first valve core 1, that is, the first blind holes 102 do not penetrate the circumferential outer wall of the first valve core 1, but form a blocking surface, when the first valve port 31 rotates to the blocking surface, the first valve port 31 cannot be communicated with the inside of the first blind hole 102, thereby blocking the first valve port 31. The first blind hole 102 is adjacent to the first through structure 101, that is, the first through structure 101 is communicated with the first valve port 31, and the first blind hole 102 can block the unnecessary first valve port 31 according to the connection requirement of the external component.

[0074] In the embodiment, the blocking surface of the first blind hole 102 can accurately control the flow direction of the fluid, by blocking or opening the first valve port 31, the accurate guidance of the fluid in the system is realized, and by blocking the first valve port 31 through the blocking surface of the first blind hole 102, the sealing property of the system is enhanced, the risk of fluid leakage is reduced, and the reliability of the system is improved. In addition, the cooperation of the first blind hole 102 and the first through structure 101 allows the fluid to flow efficiently between components, reduces the resistance of fluid flow, improves the efficiency of fluid flow, and provides more freedom of adjustment without being limited to the direct alignment of the first valve port 31.

[0075] For reference Figures 6 to 11As shown, the first valve core 1 has a first wall surface 11, a second wall surface 12 and a third wall surface 13 which are unfolded in sequence, with the unfolded surface in the circumferential direction of the first valve core 1 as the projection surface; the first wall surface 11 comprises a first first through-structure T11, a second first through-structure T12, a first first blind hole M11, a second first blind hole M12 and a first communication hole 103; the first first through-structure T11, the first first blind hole M11 and the second first through-structure T12 are arranged side by side, and the first first through-structure T11 and the second first through-structure T12 are arranged vertically; the second first blind hole M12 is arranged vertically on the first first through-structure T11, the first communication hole 103 is arranged vertically on the first first blind hole M11, one end of the first communication hole 103 penetrates through the circumferential outer wall of the first valve core 1, the other end of the first communication hole 102 penetrates through the bottom wall of the first valve core 1, the third first through-structure T13 is arranged vertically on the second first through-structure T12, the third first through-structure T13 is arranged horizontally, the first end of the third first through-structure T13 extends to the first wall surface 11, and the second end of the third first through-structure T13 extends to the second wall surface 12;

[0076] For reference Figures 6 to 11 As shown, the second wall surface 12 comprises a fourth first through-structure T14, a fifth first through-structure T15, a sixth first through-structure T16 and a third first blind hole M13; the third first blind hole M13 and the fourth first through-structure T14 are arranged side by side, the second end of the third first through-structure T13 is arranged vertically on the third first blind hole M13, the fourth first through-structure T14 is arranged horizontally, the fifth first through-structure T15 and the sixth first through-structure T16 which are arranged vertically are arranged on the fourth first through-structure T14, and the fifth first through-structure T15 and the sixth first through-structure T16 are arranged side by side;

[0077] For reference Figures 6 to 11As shown, the third wall surface 13 includes a seventh first through structure T17, an eighth first through structure T18, a ninth first through structure T19, a fourth first blind hole M14, and a fifth first blind hole M15. The seventh first through structure T17 and the fourth first blind hole M14 are arranged side by side, the seventh first through structure T17 is arranged transversely, the eighth first through structure T18 is arranged vertically on the seventh first through structure T17, and the ninth first through structure T19 and the fifth first blind hole M15 are arranged side by side. The first end of the ninth first through structure T19 and the first end of the fifth first blind hole M15 extend toward the eighth first through structure T18, and the second end of the ninth first through structure T19 and the second end of the fifth first blind hole M15 extend toward the vertical direction of the fourth first blind hole M14.

[0078] Specifically, the first through structure 101, the first blind hole 102, and the first communication hole 103 arranged on the first wall surface 11, the second wall surface 12, and the third wall surface 13 make full use of the structural characteristics of the first valve core 1, and are aligned with the first valve port 31 by rotating. The arrangement of the first through structure 101, the first blind hole 102, and the first communication hole 103 arranged on the first wall surface 11, the second wall surface 12, and the third wall surface 13 in this embodiment is arranged according to the number of connections and the through characteristics of external components. Such an arrangement can enable the air conditioning system to adjust the rotation position of the first valve core 1 according to different modes.

[0079] In this embodiment, by arranging multiple through structures and blind holes on different wall surfaces, complex fluid control logic can be achieved to meet the diversified fluid flow requirements. This arrangement can effectively distribute fluid from multiple inlets to multiple outlets, improve the efficiency and flexibility of fluid distribution, realize more fluid channels in limited space, improve space utilization, and make each part of the valve core more modularized for maintenance and repair by maintenance personnel.

[0080] It is worth noting that during the rotation of the first valve core 1, the first wall surface 11 or the second wall surface 12 or the third wall surface 13 is not completely aligned with the first mounting surface 301. In this embodiment, in order to more clearly describe the arrangement of the first through structure 101, the first blind hole 102, and the first communication hole 103, the first valve core 1 is divided into three wall surfaces. In addition, when the first valve core 1 is rotated to different rotation positions, the size of the area aligned with the first mounting surface 301 is approximately the size of each wall surface, that is, the circumferential outer wall of the first valve core 1 is aligned with the first mounting surface 301 by rolling clockwise or counterclockwise.

[0081] For reference Figures 12 to 17 As shown in the figure, the second conducting structure 201 communicates with two second valve ports 32, and the second valve core 2 is expanded in the circumferential direction, with the expanded surface as the projection surface. Part of the second conducting structure 201 is arranged horizontally, and the two second valve ports 32 are arranged side by side. Part of the second conducting structure 201 is arranged vertically, and the two second valve ports 32 are arranged in the same column.

[0082] Specifically, the second conducting structure 201 is arranged in the same way as the first conducting structure 101. The second conducting structure 201 is arranged in this way considering that, in the circulation process of the fluid, the fluid usually flows from the outlet of one component to the inlet of another component. In this embodiment, the second conducting structure 201 is arranged to communicate with two second valve ports 32. After the two second valve ports 32 and the second conducting structure 201 are communicated, one of the second valve ports 32 serves as the outlet interface of one component, and the other second valve port 32 serves as the inlet interface of another component. In this way, the fluid flows from the outlet of one component into the second conducting structure 201 and then flows into the inlet interface of another component, thereby realizing the circulation of the fluid between components through the valve device. Since the second valve core 2 of this embodiment is provided with multiple second conducting structures 201 in the circumferential direction, when the second valve core 2 is expanded in the circumferential direction, the expanded surface is rectangular. During the rotation of the second valve core 2, the second conducting structure 201 can be arranged horizontally or vertically. When the two adjacent second valve ports 32 are rotated to different rotation positions according to the second valve core 2, the two second valve ports 32 can be arranged side by side or in the same column with one second conducting structure 201. Even if only one second valve port 32 communicates with one conducting structure, the second valve port 32 does not need to be connected to the interface of the external component.

[0083] In this embodiment, the second conducting structure 201 arranged horizontally and vertically can flexibly configure the fluid path as needed, realize complex fluid control logic, realize more fluid channels in a limited space, and improve space utilization. Moreover, the two second valve ports 32 are communicated through one second conducting structure 201, which can reduce the resistance of the fluid in the system and improve the efficiency of the fluid circulation. This embodiment can reduce the number of valves required by optimizing the layout of the second conducting structure 201, simplify the system design, reduce the manufacturing and maintenance costs, ensure the smooth flow of the fluid from the outlet of one component to the inlet of another component, reduce the risk of fluid leakage, and improve the reliability of the system.

[0084] For reference Figures 12 to 17 As shown in the figure, the second conducting structure 201 is a second groove, the second groove penetrates the circumferential outer wall of the second valve core 2, one end of the second groove communicates with one second valve port 32, the other end of the second groove communicates with one second valve port 32, and the second channel is formed between the two second valve ports 32.

[0085] Specifically, the second conduction structure 201 is formed by slotting the second spool 2 to form a second channel, and the second groove has a circular arc-shaped chamfer with the cross section of the second spool 2 as the projection surface, avoiding the existence of dead angles. After the two ends of the second groove are respectively communicated with the second valve ports 32, the inlet of the second channel extends to one of the second valve ports 32, and the outlet of the second channel extends to the other valve port.

[0086] In this embodiment, the second groove combined with the arrangement of the two second valve ports 32 can connect the two second valve ports 32 into a channel, optimizing the flow path of the fluid, reducing the flow resistance, and thus improving the efficiency of fluid circulation. Moreover, the arrangement of the groove can provide better sealing effect, reduce the risk of fluid leakage, and improve the reliability of the system. The opening of the second groove can fully dock with the second valve port 32, ensuring that the second valve port 32 is more easily communicated with the second conduction structure 201 during the rotation of the second spool 2.

[0087] As a specific embodiment, the first conduction structure 101 and the second conduction structure 201 are both groove structures, and the conduction structure functions to connect two valve ports. In other embodiments, a through hole can be formed on the circumferential outer wall of the spool, one end of the through hole penetrates through the circumferential outer wall of the spool, and the other end of the through hole penetrates into the spool to a certain length and then penetrates out of the circumferential outer wall of the spool. From the circumferential outer wall of the spool, it appears that two holes are formed on the circumferential outer wall of the first spool 1, but a channel is formed inside the spool. One valve port can be communicated with one of the holes, and the other first valve port 31 is communicated with the other hole, so as to form a first conduction structure 101 on the first spool 1. In other embodiments, both the conduction structure formed by the through hole and the groove structure can be used, and the two ways can be flexibly arranged.

[0088] For reference Figures 12 to 17 As shown in the figure, with the unfolded surface in the circumferential direction of the second spool 2 as the projection surface, the second spool 2 has a fourth wall surface 21, a fifth wall surface 22, and a sixth wall surface 23 unfolded in sequence; the fourth wall surface 21 includes a first second conduction structure T21, a second second conduction structure T22, and a third second conduction structure T23; the first second conduction structure T21 and the second second conduction structure T22 are arranged side by side, the first second conduction structure T21 is vertically arranged, the second second conduction structure T22 is horizontally arranged, and the third second conduction structure T23 is arranged in the vertical direction of the second second conduction structure T22, and the third second conduction structure T23 is horizontally arranged.

[0089] For reference Figures 12 to 17As shown, the fifth wall surface 22 includes a fourth second conduction structure T24, a fifth second conduction structure T25, and a sixth second conduction structure T26; the fourth second conduction structure T24, the fifth second conduction structure T25, and the sixth second conduction structure T26 are arranged side by side in sequence, and the fourth second conduction structure T24, the fifth second conduction structure T25, and the sixth second conduction structure T26 are vertically arranged.

[0090] For reference Figures 12 to 17 As shown, the sixth wall surface 23 includes a seventh second conduction structure T27, a second blind hole 202, and two second communication holes 203; the two second communication holes 203 and the second blind hole 202 are arranged side by side in sequence, one end of the two second communication holes 203 respectively penetrates the circumferential outer wall of the second valve core 2, and the other end of the two second communication holes 203 respectively penetrates the top wall of the second valve core 2; the seventh second conduction structure T27 is horizontally arranged, the first end of the seventh second conduction structure T27 extends in the vertical direction of one of the second communication holes 203, and the second end of the seventh second conduction structure T27 extends in the vertical direction of the other second communication hole 203; it is worth noting that the extension here refers to the extension direction of the end of the second conduction structure 201, and the seventh second conduction structure T27 is not in communication with the second communication hole 203.

[0091] Specifically, since the number of second valve ports 32 arranged on the second mounting surface 302 is less than the number of first valve ports 31 arranged on the first mounting surface 301, the arrangement of the second valve ports 32 on the second mounting surface 302 is relatively simple, and the arrangement of the second conduction structure 201, the second blind hole 202, and the second communication hole 203 on the fourth wall surface 21, the fifth wall surface 22, and the sixth wall surface 23 fully utilizes the structural characteristics of the second valve core 2, and aligns the second valve port 32 with the second conduction structure 201, the second blind hole 202, and the second communication hole 203 through rotation. The arrangement of the second conduction structure 201, the second blind hole 202, and the second communication hole 203 on the fourth wall surface 21, the fifth wall surface 22, and the sixth wall surface 23 in this embodiment is arranged according to the connection number and conduction characteristics of the external components, and such arrangement can enable the air conditioning system to adjust the rotation position of the first valve core 1 according to different modes.

[0092] In this embodiment, by arranging multiple conduction structures and blind holes on different wall surfaces, complex fluid control logic can be realized to meet the diversified fluid flow requirements. This arrangement can effectively distribute fluid from multiple inlets to multiple outlets, improve the efficiency and flexibility of fluid distribution, realize more fluid channels in limited space, improve space utilization, and make each part of the valve core more modularized, facilitating maintenance and repair by maintenance personnel.

[0093] It is worth mentioning that in the process of rotating the second valve core 2, the fourth wall surface 21 or the fifth wall surface 22 or the sixth wall surface 23 is not required to be completely aligned with the second mounting surface 302. In order to more clearly describe the arrangement of the second through-connection structure 201, the second blind hole 202 and the arrangement of the second communication hole 203, the unfolded surface of the second valve core 2 is divided into three wall surfaces in this embodiment. In addition, when the second valve core 2 is rotated to different rotating positions, the size of the area aligned with the second mounting surface 302 is approximately equal to the size of the area of each wall surface, that is, the circumferential outer wall of the second valve core 2 is aligned with the second mounting surface 302 in a clockwise or counterclockwise rolling manner.

[0094] As a specific embodiment, the length of the first valve core 1 is greater than the length of the second valve core 2 in the axial direction of the valve seat 3. In this embodiment, the length and width of the first groove and the second groove are the same, and in addition to the vertical first groove, the first blind hole 102 or the first groove can be transversely arranged in the vertical direction of the first groove on the first wall surface 11, the second wall surface 12 and the third wall surface 13 of the first valve core 1. Since the length of the second valve core 2 is shorter than the length of the first valve core 1, the second blind hole 202 or the second groove is no longer arranged in the vertical direction of the second groove when the second groove is vertically arranged on the fourth wall surface 21, the fifth wall surface 22 and the sixth wall surface 23 of the second valve core 2.

[0095] As a specific embodiment, when the first valve core 1 has the first wall surface 11, the second wall surface 12 and the third wall surface 13 unfolded in sequence, and the second valve core 2 has the fourth wall surface 21, the fifth wall surface 22 and the sixth wall surface 23 unfolded in sequence, the first through-connection structure 101 and the second through-connection structure 201 are both groove structures, and the arrangement of the plurality of first through-connection structures 101, the plurality of second through-connection structures 201, the plurality of first blind holes 102, the plurality of second blind holes 202, the first communication hole 103 and the second communication hole 203 on the wall surface is the best arrangement of this embodiment. This arrangement can meet different operating modes of the air conditioning system.

[0096] For reference Figures 1 to 17As shown, the valve seat 3 is provided with a partition plate 303, which separates the inner cavity of the valve seat 3 into a first chamber and a second chamber, the first valve core 1 is installed in the first chamber, and the second valve core 2 is installed in the second chamber; at least one first communication hole 103 is further provided in the circumferential direction of the first valve core 1, one end of the first communication hole 103 penetrates the circumferential outer wall of the first valve core 1, and the other end of the first communication hole 103 extends into the first valve core 1 and extends towards the partition plate 303; at least one second communication hole 203 is further provided in the circumferential direction of the second valve core 2, one end of the second communication hole 203 penetrates the circumferential outer wall of the second valve core 2, and the other end of the second communication hole 203 extends into the second valve core 2 and extends towards the partition plate 303; the partition plate 303 is provided with an axial through hole 331, and the first communication hole 103 and the second communication hole 203 respectively communicate with the axial through hole 331.

[0097] Specifically, in the present embodiment, the first communication hole 103 is formed on the first wall surface 11, and the second communication hole 203 is formed on the sixth wall surface 23. Specifically, the first end of the third first communication structure T13 is also substantially the first communication hole 103. The third first communication structure T13 is not only a groove structure, but also the first end of the third first communication structure T13 penetrates the bottom wall of the first valve core 1 in the axial direction. During the rotation of the first valve core 1 and the second valve core 2, when the first communication hole 103 on the first valve core 1 and the second communication hole 203 on the second valve core 2 are both in communication with the axial through hole 331 on the partition plate 303, at this time, the interiors of the first valve core 1 and the second valve core 2 form an axial passage, that is, in the vertical direction, one first valve port 31 communicates with one second valve port 32 through the axial passage, realizing the communication between the two valve cores.

[0098] In the present embodiment, the communication hole allows the interiors of the first valve core 1 and the second valve core 2 to form an axial passage, allowing fluid to flow between the two valve cores. This internal communication method is conducive to controlling the flow of fluid, and by rotating the first valve core 1 and the second valve core 2, the alignment of the communication hole with the axial through hole 331 on the partition plate 303 can be controlled, thereby opening or closing the fluid flow path. This precise control ensures that the fluid flows along the predetermined path. The communication hole and the axial passage can substantially allow the valve core to realize different fluid communication combinations at different positions, providing more control options and increasing the flexibility and adaptability of the system.

The compressor 51, the evaporating side heat exchanger 52, the condensing side heat exchanger 53, and the throttle valve 41 are conventional air conditioning systems, and the system circulates refrigerant. The heat of the outside heat exchanger 55, the water tank 56, the motor control end 57, the battery 58, the first indoor heat exchanger 59, and the second indoor heat exchanger 60 is utilized or dissipated to the above components, and the heat is utilized by means of water circulation.

The arrangement of the plurality of first conductive structures 101, the plurality of second conductive structures 201, the plurality of first blind holes 102, the plurality of second blind holes 202, the first communication hole 103, and the second communication hole 203 of the embodiment can meet the connection requirements of the six modes.

The fourth second communication structure T24 of the second valve core 2 communicates the third interface flow path J3 and the ninth interface flow path J9, the fifth second communication structure T25 communicates the fourth interface flow path J4 and the seventh interface flow path J7, and the sixth second communication structure T26 communicates the tenth interface flow path J10 and the sixth interface flow path J6. Corresponding to the flow paths on the air conditioning system, the first path is the ninth interface flow path J9-third interface flow path J3-fourth interface flow path J4-seventh interface flow path J7-eighth interface flow path J8-fifth interface flow path J5-sixth interface flow path J6-tenth interface flow path J10, and the second path is the first interface flow path J1-eleventh interface flow path J11-twelfth interface flow path J12-thirteenth interface flow path J13-fourteenth interface flow path J14-second interface flow path J2. In the sixth mode, the air conditioner runs in the dehumidification mode in humid weather.

[0108] By classifying and summarizing 13 kinds of running scenes of the air conditioning system 13, the running state of the fourteen-way valve can be simplified to 6 combinations, for example, two conditions of charging the battery and preheating the vehicle in winter low temperature and starting the vehicle, the vehicle outside heat exchanger runs low temperature cooling water, the battery end runs high temperature cooling water, and the vehicle inside heat exchanger runs high temperature cooling water. When the vehicle cabin does not need to be heated, the vehicle inside heat exchanger only passes through the high temperature cooling water, and the blower is not started. Further, the two scenes of the fourteen-way valve state can be combined into one, that is, the valve core state combination of mode one. The initial state of the first valve core 1 and the second valve core 2 is defaulted to the first rotation position, and then rotated by a corresponding angle according to the instruction of the air conditioning system running mode to switch, for example, after the air conditioning system runs, the instruction of the air conditioning system running mode three is received, the valve core first actuator 41 and the valve core second actuator 42 start to act, the valve core first actuator 41 drives the first valve core 1 to rotate 160° to run in the third rotation position, and the valve core second actuator 42 drives the second valve core 2 to rotate 40° to run in state 2. In this embodiment, the first valve core 1 is provided with 4 kinds of running states, the second valve core 2 is provided with 4 kinds of running states, and after the two states are combined, 6 kinds of air conditioning system running modes are combined, and the controller logic is simplified.
