[0039] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0040] like Figures 1 to 5 As shown, this embodiment of the disclosure provides a distribution box 30 for a multi-split air conditioning system and a multi-split air conditioning system. The distribution box 30 is connected to multiple air supply ducts 21, and the multiple air supply ducts 21 are connected to multiple rooms. The indoor unit 10 can supply air to multiple rooms through the distribution box 30 and the multiple air supply ducts 21. At the same time, simply driving the valve body element 32 to rotate can block or unblock the corresponding air outlet 311 and air supply duct 21. This configuration can reduce the manufacturing cost of the distribution box 30 and facilitate its maintenance in the future.

[0041] like Figures 1 to 5 As shown, this embodiment of the disclosure provides a distribution box 30 for a multi-split air conditioning system, the multi-split air conditioning system including a fan; the distribution box 30 includes: a housing 31 and multiple valve elements 32. The housing 31 is provided with an air inlet 312 and multiple air outlets 311, the air inlet 312 is connected to the air outlet end of the fan, and the multiple air outlets 311 are respectively connected to the air inlet 312 through air ducts; the multiple valve elements 32 are respectively disposed at the multiple air outlets 311, and the valve elements 32 are rotatably connected to the side wall of the air outlet 311 through a rotating shaft; wherein, the valve elements 32 rotate around the rotating shaft to block or unblock the corresponding air outlet 311.

[0042] Specifically, the multi-split air conditioning system also includes an indoor unit 10, an outdoor unit, and an air supply duct assembly. The indoor unit 10 includes a casing, and a fan is housed within the casing. The outdoor unit is located outdoors and is connected to the indoor unit 10 via ductwork. The housing 31 of the distribution box 30 is located on one side of the indoor unit 10 casing, and the air inlet 312 of the distribution box 30 is connected to the air outlet of the fan. The air supply duct assembly includes multiple air supply pipes 21, and each of the multiple air supply pipes 21 is connected to multiple air outlets 311. The air inlet 312 and the air outlet 311 are positioned opposite each other on both sides of the housing 31, and an air duct is provided inside the housing 31 to connect the air inlet 312 and the air outlet 311. A valve element 32 is provided at each of the multiple air outlets 311, and the valve element 32 is used to block and unblock the corresponding air outlet 311. This design reduces the manufacturing cost of the air distribution box 30 and facilitates its maintenance in the future.

[0043] In practical applications, when a multi-split air conditioner is operating, the fan outlet blows air towards the air inlet 312, and then the air flows through the duct to multiple air outlets 311. If a user needs to cool or heat a specific room, they can control the corresponding valve element 32 to open the corresponding air outlet 311, allowing airflow to enter the corresponding air supply duct 21 and be blown into that room, thus satisfying the user's need for cooling or heating. Simultaneously, the valve elements 32 for other rooms can block their corresponding air outlets 311 to prevent air from flowing into other rooms through the air supply duct 21, thereby reducing the operating load of the multi-split air conditioner. This configuration reduces the energy consumption of the multi-split air conditioning system while still satisfying the user's need for cooling or heating in designated rooms, thereby improving the user experience.

[0044] like Figures 3 to 5 As shown, in some embodiments, the multi-split air conditioning system further includes a control device; the air distribution box 30 further includes multiple drive motors 33. The multiple drive motors 33 are respectively connected to the rotating shafts of multiple valve body elements 32; wherein, the control device is electrically connected to the multiple drive motors 33 respectively, and the control device can control the multiple drive motors 33 to independently drive the corresponding valve body elements 32 to rotate.

[0045] Specifically, the number of drive motors 33 is the same as the number of valve body elements 32, so that multiple drive motors 33 can independently drive multiple valve body elements 32. Each drive motor 33 is located on one side of a valve body element 32, and each drive motor 33 has an output shaft corresponding to a valve body element 32, which is connected to the rotating shaft of the valve body element 32. The control device includes a control panel or remote control, allowing the user to control the drive motors 33 to rotate the valve body elements 32, thereby clearing or blocking the corresponding air outlets 311.

[0046] like Figures 3 to 5 As shown, in some embodiments, when the valve body element 32 clears the air outlet 311, the drive motor 33 can drive the valve body element 32 to rotate between a first preset angle and a second preset angle to adjust the opening of the air outlet 311.

[0047] Specifically, when the valve body element 32 is clear of the air outlet 311, the drive motor 33 can rotate the valve body element 32 between 5° and 90°. For example, the drive motor 33 can rotate the valve body element 32 to 5°, 30°, 60°, or 90°, so that the opening degree of the corresponding air outlet 311 is 5%, 30%, 60%, or 100%. With this setting, the user can adjust the cooling capacity of the corresponding room by adjusting the opening degree of the air outlet 311.

[0048] like Figures 3 to 5 As shown, in some embodiments, the valve body element 32 is configured as a plate; a rotating shaft is disposed in the middle of the valve body element 32 and is rotatably connected to the side wall surface of the middle of the air outlet 311; wherein the valve body element 32 can rotate about its centerline to separate the air outlet 311.

[0049] Specifically, the air outlet 311 is configured as a circular air outlet 311, and the valve body element 32 is configured as a corresponding circular plate. A rotating shaft is provided in the middle of the valve body element 32, and the rotating shaft is rotatably connected to the middle of the air outlet 311. In this way, the valve body element 32 can rotate circumferentially around the rotating shaft to block or unblock the corresponding air outlet 311.

[0050] In practical applications, the rotating shaft can be arranged horizontally on the left and right sides of the valve body element 32, in which case the drive motor 33 is located on the left or right side of the valve body element 32. Similarly, the rotating shaft can also be arranged vertically on the upper and lower sides of the valve body element 32, in which case the drive motor 33 is located above or below the valve body element 32.

[0051] like Figures 3 to 5 As shown, in some embodiments, the air distribution box 30 further includes a plurality of air guide plates 34. The plurality of air guide plates 34 are respectively disposed corresponding to a plurality of air outlets 311; wherein, the air guide plates 34 are disposed in the air duct between the air outlets 311 and the air inlets 312.

[0052] Specifically, multiple air guide plates 34 are spaced apart within the air duct and located between the air outlet 311 and the air inlet 312. At least one air guide plate 34 is provided between any two adjacent air outlets 311 to form multiple sub-air ducts within the air duct, allowing the air inlet 312 to connect with the multiple air outlets 311 through these sub-air ducts. This arrangement helps to avoid airflow turbulence within the air duct.

[0053] like Figures 3 to 5As shown, in some embodiments, the air guide plate 34 includes a fixed plate 341 and a movable plate 342. The fixed plate 341 is fixedly disposed on one side of the air outlet 311; the movable plate 342 is disposed on the side of the fixed plate 341 opposite to the air outlet 311, and the movable plate 342 is rotatably connected to the fixed plate 341 via a pivot; wherein, the movable plate 342 can rotate horizontally around the pivot.

[0054] Specifically, the fixed plate 341 is fixedly disposed on one side of the air outlet 311 to separate two adjacent air outlets 311. The movable plate 342 is rotatably connected to the side of the fixed plate 341 opposite to the air outlet 311 via a pivot, allowing the movable plate 342 to rotate around the pivot. This arrangement allows the user to rotate the movable plate 342 to one side, reducing the width of the sub-air duct on that side and increasing the width of the sub-air duct on the other side, thereby facilitating the adjustment of the airflow at the air outlets 311 on both sides of the movable plate 342.

[0055] Optionally, limit protrusions are provided on both sides of the movable plate 342. When the movable plate 342 rotates to its extreme position on both sides, the limit protrusions can stop the movable plate 342 from continuing to rotate.

[0056] like Figures 3 to 5 As shown, in some embodiments, a groove 313 is provided in the air duct; the movable plate 342 also includes a slider 343, which is embedded in the groove 313 so that the slider 343 can slide along the groove 313.

[0057] Specifically, the inner wall of the air duct is provided with a groove 313, and a slider 343 is provided on the side of the movable plate 342 away from the fixed plate 341, with the slider 343 embedded in the groove 313. In this way, when the movable plate 342 rotates, the groove 313 can guide the side of the movable plate away from the fixed plate 341 through the slider 343.

[0058] Optionally, the slide groove 313 is provided with multiple positioning protrusions, and the multiple positioning protrusions are spaced apart along the slide groove 313. After the slider 343 slides to the preset position, the positioning protrusions can position the slider 343 to prevent the movable plate 342 from being pushed by the airflow in the air duct.

[0059] like Figures 3 to 5 As shown, in some embodiments, the slide groove 313 is disposed on the bottom wall surface of the air duct, and the slide groove 313 is disposed in the form of penetrating the bottom wall surface of the air duct; wherein, the slider 343 extends from inside the air duct through the slide groove 313 to the outside of the air duct.

[0060] Specifically, a groove 313 is provided through the bottom wall of the air duct, so that the slider 343 can extend from inside the air duct through the groove 313 to outside the air duct. In this way, the part of the slider 343 extending outside the air duct can form a handle, so that the user can easily adjust the position of the movable plate 342 by using the handle.

[0061] like Figure 1 and Figure 2 As shown in the figure, this disclosure also provides a multi-split air conditioning system including: an indoor unit 10 and the aforementioned air distribution box 30 for the multi-split air conditioning system. The indoor unit 10 includes a fan; the air distribution box 30 for the multi-split air conditioning system is disposed on one side of the indoor unit 10, and the fan is connected to the air inlet 312 of the air distribution box 30.

[0062] Specifically, the multi-split air conditioning system using the air distribution box 30 provided in this application can reduce the manufacturing cost of the air distribution box 30 and facilitate the maintenance of the air distribution box 30 in the future.

[0063] like Figure 1 and Figure 2 As shown, in some embodiments, the multi-split air conditioning system further includes an air supply duct assembly. The air supply duct assembly includes multiple air supply pipes 21, which are respectively connected to multiple air outlets 311 of the distribution box 30.

[0064] Specifically, the air supply duct assembly includes multiple air supply ducts 21, each connected to multiple air outlets 311. This allows users to select the appropriate air supply duct 21 to deliver air into the room according to their needs. This configuration reduces the energy consumption of the multi-split air conditioning system while still meeting the user's requirements for cooling or heating a designated room, thereby improving the user experience.

[0065] like Figure 1 and Figure 2 As shown, optionally, the multi-split air conditioning system also includes multiple return air ducts 22, and each room is provided with at least one supply air duct 21 and one return air duct 22. The return air duct 22 is connected to the air inlet of the fan. In this way, the fan can supply air to the room through the supply air duct 21 and return air through the return air duct 22 to achieve air circulation.
