[0034] The technical solutions in the embodiments (or, the implementation manners) of the present application will be clearly and completely described below with reference to the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings indicate the same or similar elements unless otherwise indicated.

[0035] If the application embodiments involve directional indications or positional relationships (such as up, down, left, right, front, back, inner, outer, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationship, movement, etc. between the components in a certain specific posture (as shown in the drawings); if the specific posture changes, the directional indication or positional relationship also changes accordingly. In addition, the terms "first", "second", etc. in the application embodiments are only used for convenience of description, and cannot be understood as indicating or implying relative importance.

[0036] As shown in Figures 1 to 9 The valve of the present application includes a valve housing 1 and a valve core 2. The valve core 2 is arranged to rotate in the valve housing 1, so that the valve core 2 can rotate around its central axis. The valve housing 1 includes a housing body 11, a first through pipe 12, a second through pipe 13, and a plurality of third through pipes 14. The first through pipe 12 is fixed to the upper side plate 111 of the housing body 11, the second through pipe 13 is fixed to the lower side plate 112 of the housing body 11, and the plurality of third through pipes 14 are fixed to the circumferential side plate 113 of the housing body 11.

[0037] The valve core 2 includes a first flow channel 21, a second flow channel 22, and a plurality of third flow channels 23. Part of the third flow channels 23 only communicate with the first flow channel 21, and the rest of the third flow channels 23 only communicate with the second flow channel 22. The opening of the first flow channel 21 communicates with the first through pipe 12, the opening of the second flow channel 22 communicates with the second through pipe 13, and the plurality of third flow channels 23 respectively communicate with the plurality of third through pipes 14.

[0038] Thus, the valve core 2 is rotatably arranged in the valve housing 1, and the outlets of the plurality of third flow channels 23 can change positions with the rotation of the valve core 2, so that each third flow channel 23 can be communicated with different third through pipes 14, thereby increasing the different communication modes and switching functions of the valve, and when the valve is applied to the compressor unit, the compressor unit can switch between the refrigeration and heat pump operating conditions, and without reverse operation, the defrosting or ice melting function can be realized, so that the heating effect of the compressor unit is more stable, and the use experience of people is improved.

[0039] In some embodiments, the first through pipe 12 and the second through pipe 13 are respectively located on opposite sides of the shell body 11, and when the valve core 2 rotates, in order to make the communication between the first flow channel 21 and the first through pipe 12 and the second flow channel 22 and the second through pipe 13 more stable, the first through pipe 12 and the second through pipe 13 are coaxially arranged. Further, the axis of the first through pipe 12 and the axis of the second through pipe 13 coincide with the central axis of the valve core 2, and the center of the opening of the first flow channel 21 and the center of the opening of the second flow channel 22 are located on the central axis of the valve core 2. The opening of the first flow channel 21 is located on the top side of the valve core 2, and the opening of the second flow channel 22 is located on the bottom side of the valve core 2. The first flow channel 21 is always communicated with the first through pipe 12, and the second flow channel 22 is always communicated with the second through pipe 13.

[0040] Along the circumference of the valve core 2, the plurality of third through pipes 14 are uniformly spaced on the peripheral side plate 113 of the shell body 11. Specifically, along the circumference of the valve core 2, the included angle between any two adjacent third through pipes 14 is equal to the included angle between any other two adjacent third through pipes 14. The third flow channels 23 are correspondingly arranged with the third through pipes 14. Specifically, the openings of the plurality of third flow channels 23 are located on the peripheral side of the valve core 2, the number of the third flow channels 23 corresponds to the number of the third through pipes 14, and along the circumference of the valve core 2, the angular interval between the openings of any two adjacent third flow channels 23 is equal to the included angle between any two adjacent third through pipes 14.

[0041] When the valve core 2 rotates, in order to enable different third flow channels 23 and different third through pipes 14 to communicate smoothly, the axes of all third through pipes 14 and the centers of the openings of all third flow channels 23 are on the same horizontal plane. In order to prevent liquid leakage when the valve core 2 communicates with the valve housing 1, the diameter of the opening of the first flow channel 21 is the same as the inner diameter of the first through pipe 12, the diameter of the opening of the second flow channel 22 is the same as the inner diameter of the second flow channel 22, and the diameter of the opening of the third flow channel 23 is the same as the inner diameter of the third through pipe 14. Of course, sealing members can also be arranged at the connection between the opening of the first flow channel 21 and the first through pipe 12, the connection between the opening of the second flow channel 22 and the second flow channel 22, and the connection between the opening of the third flow channel 23 and the third through pipe 14.

[0042] The valve preferably but not limited to a six-way valve, and the third through pipe 14 and the third flow channel 23 are both four. Among them, along the circumference of the valve core 2, the included angle between any two adjacent third through pipes 14 and the included angle between any two adjacent third flow channel 23 openings are both 90 degrees. Further, the third through pipe 14 includes through pipe one 141, through pipe two 142, through pipe three 143 and through pipe four 144. The through pipe one 141, the through pipe two 142, the through pipe three 143 and the through pipe four 144 are uniformly spaced on the circumferential side plate 113 of the shell body 11, that is, the through pipe one 141 is oppositely arranged with the through pipe three 143, and the through pipe two 142 is oppositely arranged with the through pipe four 144.

[0043] Among the four third flow channels 23, two adjacent third flow channels 23 are communicated with the first flow channel 21, and the other two adjacent third flow channels 23 are communicated with the second flow channel 22. Under the rotation of the valve core 2, each third flow channel 23 can be respectively communicated with the through pipe one 141, the through pipe two 142, the through pipe three 143 and the through pipe four 144.

[0044] When the valve is other way valve, the first through pipe 12, the second through pipe 13, the first flow channel 21 and the second flow channel 22 are all one, and are coaxially arranged, while the third through pipe 14 and the third flow channel 23 are provided with multiple and the same number, for example, if the valve is a seven-way valve, the third through pipe 14 and the third flow channel 23 are five; if the valve is an eight-way valve, the third through pipe 14 and the third flow channel 23 are six. And when the valve is other way valve, the third through pipe 14 is also uniformly spaced on the circumferential side plate 113 of the shell body 11, and the opening of the third flow channel 23 is also uniformly spaced on the circumferential side of the valve core 2.

[0045] Further combining Figures 10 to 13 As shown, in some embodiments, in order to make the valve core 2 rotatable, the valve can also include a driving assembly 3. Part of the driving assembly 3 is arranged in the shell body 11 and in contact with the valve core 2 to drive the valve core 2 to rotate. Along the circumference of the valve core 2, the driving assembly 3 is located between the through pipe one 141 and the through pipe four 144. The driving assembly 3 includes a power piece 31 and a transmission piece 32. The power piece 31 is fixed to the upper side plate 111 of the shell body 11 and connected with the transmission piece 32, and the power piece 31 is used to drive the transmission piece 32 to rotate. The transmission piece 32 is located in the shell body 11 and cooperates with the valve core 2.

Specifically, the circumferential side of the transmission piece 32 is provided with a first tooth group 321, and the circumferential side of the valve core 2 is provided with a second tooth group 24, and the first tooth group 321 is engaged with the second tooth group 24. In order to make the transmission piece 32 and the valve core 2 more stable when engaged and rotated, the second tooth group 24 is provided with at least two groups, and along the thickness direction of the valve core 2, a plurality of second tooth groups 24 are spaced, and the openings of the third flow channels 23 are located between the second tooth groups 24.

[0047] In order to reduce the manufacturing difficulty of the transmission member 32 and improve the manufacturing efficiency, the number of the first tooth group 321 corresponds to the number of the second tooth group 24, and the first tooth group 321 is engaged with the second tooth group 24 one by one. In order to make the third flow channel 23 more airtight when communicating with the third pipe 14, the second tooth group 24 does not exceed the peripheral side surface of the valve core 2, and the first tooth group 321 exceeds the peripheral side surface of the transmission member 32 to be engaged in the second tooth group 24.

[0048] In other embodiments, the transmission member 32 and the valve core 2 can also be connected through a transmission belt to drive the valve core 2 to rotate.

[0049] In some embodiments, the valve core 2 is provided with an oil guide groove 25. The oil guide groove 25 is arranged on the top side and the bottom side of the valve core 2 respectively, so that the lubricating oil in the oil guide groove 25 can lubricate the valve core 2, making the valve core 2 rotate more smoothly.

The exhaust end 41 communicates with the first pipe 12, the suction end 42 communicates with the second pipe 13, and the two third pipes 14 arranged symmetrically communicate with each other. Taking the valve as an example of a six-way valve, the pipe one 141 is arranged opposite to the pipe three 143 and can communicate with each other through a pipe outside the valve housing 1, and the pipe two 142 is arranged opposite to the pipe four 144 and can communicate with each other through a pipe outside the valve housing 1.
