[0031] Figures 1 to 5The figure shows an air guide device 200 and an indoor unit provided by the utility model. As can be seen from the figure, the utility model provides an air guide device 200, which is used for the indoor unit. The indoor unit has an air duct 110 and an air outlet 120 that can be connected to the air duct 110; the air guide device 200 is located at the air outlet 120, and the air guide device 200 has an air guide surface 2231. The air guide device 200 can make the air guide surface 2231 extend outward from the air duct 110 through the air outlet 120, or can make the air guide surface 2231 retract into the air duct 110 from the outside of the air duct 110 through the air outlet 120.

[0032] In specific implementation, the wind guide device 200 has an wind guide surface 2231. By enabling the wind guide surface 2231 to be telescopically movable in and out of the air duct 110, the air supply angle and the air supply distance will change during the telescopic process. For example, if the wind guide surface 2231 extends further outward, the wind will flow along the wind guide surface 2231, and the wind will blow farther; conversely, if the wind guide surface 2231 is retracted further inward, the wind will blow closer; through the above-mentioned structural setting, the wind can be blown to a preset area, so that air can be supplied to both near and far places, that is, the range of cold and warm air flows can be made wider, which helps to improve the temperature uniformity in the entire room, improve the user's physical comfort, optimize the control experience of the indoor air environment, and solve the technical problem that the air supply angle and the air supply distance cannot be flexibly adjusted in the wind guide device 200 of the prior art.

[0033] According to one embodiment of the utility model, the wind guide device 200 includes a support unit 210 and an wind guide unit 220; the support unit 210 is arranged in the air duct 110 through the air outlet 120, and the support unit 210 has a channel 211; the channel 211 runs through the support unit 210 at both ends along a height direction H perpendicular to the support unit 210, and the end of the channel 211 is located at the air outlet 120; the wind guide surface 2231 is arranged on the wind guide unit 220; the wind guide unit 220 can be movably connected to the support unit 210, and the wind guide unit 220 can make the wind guide surface 2231 extend outward from the channel 211 through the air outlet 120, or, can make the wind guide surface 2231 retract into the channel 211 from the outside of the channel 211 through the air outlet 120.

[0034] In a specific implementation, by adding a support unit 210 and an air guide unit 220, the support unit 210 is fixed in the air duct 110 through the air outlet 120, and the channel 211 formed inside the support unit 210 provides a movement space for the air guide unit 220, so that the air guide unit 220 can move smoothly in the channel 211, and the air flow can flow out to the indoor environment; the air guide surface 2231 is arranged on the air guide unit 220, so that the position change of the air guide surface 2231 is closely related to the movement of the air guide unit 220, and the air guide unit 220 can be flexibly and movably connected to the support unit 210 This means that when the air guide unit 220 moves along the channel 211, the air guide surface 2231 can follow the air guide unit 220 to extend outward from the channel 211 through the air outlet 120, thereby expanding the air supply coverage range and changing the air supply direction; conversely, the air guide surface 2231 can also be retracted into the channel 211 along with the air guide unit 220, thereby narrowing the air supply range and adjusting the wind direction concentration; this unique structural design enables the air guide device 200 of the utility model to achieve more refined and dynamic wind direction and wind distance control, thereby improving the flexibility and efficiency of the indoor unit in adapting to different environmental conditions and user needs.

[0035] According to one embodiment of the utility model, the top wall of the support unit 210 has a avoidance hole 212; the air guide unit 220 includes a connecting mechanism 221, a first air guide plate 222 and a second air guide plate 223; the connecting mechanism 221 is located in the channel 211, one end of the connecting mechanism 221 is rotatably connected to the inner wall of the support unit 210, and the other end of the connecting mechanism 221 is rotatably connected to the first air guide plate 222; the end of the first air guide plate 222 is rotatably connected to the end of the second air guide plate 223; the second air guide plate 223 is located in the support unit 210, and is slidably connected to the inner wall of the support unit 210, and is arranged to be tilted downward along the air outlet direction (for example, horizontally); the air guide surface 2231 is arranged on the second air guide plate 223.

[0036] During specific implementation, the connecting mechanism 221 operates in the channel 211, one end of which is rotatably connected to the inner wall of the support unit 210, and the other end is rotatably connected to the first air guide plate 222. This design allows the first air guide plate 222 and the second air guide plate 223 to follow the connecting mechanism 221 to perform three-dimensional and multi-dimensional movements in the channel 211. The first air guide plate 222 and the second air guide plate 223 are connected by rotation at the end to form a foldable or unfoldable structure. This structure allows the air guide surface 2231 (arranged on the second air guide plate 223) to be flexibly extended and retracted inside and outside the channel 211 as needed, and can achieve multi-angle air supply adjustment in the extended state. The second air guide plate 223 can not only be slidably connected to the inner wall of the support unit 210, but is also designed to be tilted downward along the air outlet direction. This feature helps to guide the airflow to flow out of the air outlet 120 more smoothly, and accurately control the air supply direction and distance according to the angle change of the second air guide plate 223, thereby achieving a better airflow distribution effect.

[0037] In this embodiment, the air guide unit 220 includes a first state and a second state; in the first state, the first air guide plate 222 covers the avoidance hole 212, and the second air guide plate 223 is located outside the channel 211; in the second state, the first air guide plate 222 exposes the avoidance hole 212, and the second air guide plate 223 is located inside the channel 211.

[0038] According to one embodiment of the utility model, a first wind guide rib is provided at the bottom of the first wind guide plate 222; a second wind guide rib is provided at the bottom of the second wind guide plate 223; in the second state, the end of the first wind guide rib can be connected to the end of the second wind guide rib.

[0039] In specific implementation, the first wind guide plate 222 and the second wind guide plate 223 are respectively provided with the first wind guide rib and the second wind guide rib. In the second state, the ends of the first wind guide rib and the second wind guide rib contact each other. Such a design is intended to enhance the guidance and stability of the airflow and improve the wind direction control accuracy. When the air guide device 200 is transformed from the first state to the second state, the connection between the first wind guide rib and the second wind guide rib can form a continuous air guide channel, reduce wind resistance, and make the airflow more smoothly sent out in the set direction, which is also conducive to achieving a larger range or longer distance air supply effect.

[0040] In this embodiment, the connection mechanism 221 is in a “C” shape.

[0041] According to an embodiment of the present invention, a driving unit 230 is further included. The driving unit 230 is connected to the connecting mechanism 221 and is used to drive the connecting mechanism 221 to rotate so that the air guide unit 220 is in the first state or the second state.

[0042] During specific implementation, the driving unit 230 can realize rapid switching of the air guide unit 220 between the first state and the second state by driving the connecting mechanism 221 to rotate, making the adjustment of the air supply angle and distance more convenient and accurate, greatly improving the user experience, and reducing the inconvenience and errors caused by manual adjustment.

[0043] In this embodiment, the driving unit 230 includes a driving mechanism 231 and a transmission mechanism 232 ; the driving mechanism 231 is disposed on the inner wall of the casing 100 of the indoor unit and is rotatably connected to the connecting mechanism 221 via the transmission mechanism 232 .
