[0023] The realization of the purpose, functional features and advantages of the present application will be further described with reference to the embodiments and the accompanying drawings. Detailed implementation manners

[0024] Next, the technical solutions in the embodiments of the present application will be clearly and completely described with reference to the accompanying 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative efforts belong to the scope of protection of the present application.

[0025] The embodiments of the present application provide an air conditioner indoor unit to solve the problem that the air conditioner cannot be compatible with the air guiding comfort and large-angle air sweeping. The following will be described with reference to the accompanying drawings.

[0026] In the embodiments of the present application, as shown in Figure 1 and Figure 2 an air conditioner indoor unit includes a main body 1 and an air guiding structure. The main body 1 is provided with an air outlet 11. The air guiding structure covers the air outlet 11. The air guiding structure is provided with a plurality of air guiding openings. The air guiding structure is connected to the main body. The air guiding structure is used to move in a direction close to or away from the air outlet 11 to drive the air guiding openings to switch to the position of the air outlet 11 or hide into the main body 1.

[0027] It should be noted that the air guiding structure covering the air outlet 11 means that when the air guiding openings of the air guiding structure switch to the air outlet 11, the air outlet 11 can only be observed through the air guiding openings, and the air guiding structure blocks the air outlet 11; when the air guiding openings of the air guiding structure hide into the main body 1, the air outlet 11 is completely blocked by the air guiding structure. The air guiding structure can move close to or away from the air outlet in a sliding, rotating or other ways.

[0028] As shown in Figure 2 and Figure 3As shown, when the air conditioner indoor unit is in operation, the air guiding structure can move so that multiple air guiding openings are all switched to the air outlet 11. The multiple air guiding openings replace the area where the original air guiding structure covers the air outlet 11, so that the air flow can spread as much as possible along the extending direction of the side wall of the air outlet 11, having a larger air outlet range; and the multiple air guiding openings can slow down the air speed, and a turbulent flow can be formed between the air flows passing through the multiple air outlets 11, playing a role in softening the air and improving the discomfort caused by direct blowing; in addition, the air guiding structure can also move so that multiple air guiding openings are all switched to different positions of the air outlet 11, or several or one of the multiple air guiding plates 2 are switched to different positions of the air outlet 11, so as to adjust the air outlet air volume and the air outlet direction to meet different air outlet angle requirements.

[0029] As Figure 1 shown, when the air conditioner indoor unit is in the shutdown state, the air guiding structure can move to hide multiple air guiding openings in the main body 1 to prevent dust from entering; in the related art, there is a fitting gap between the single air guiding plate of the flip-type air guiding and the air outlet 11, while the air guiding structure in this embodiment can completely block the side wall of the air outlet 11, with a beautiful appearance. It can simultaneously meet the requirements of soft air, large-angle air sweeping and beauty.

[0030] In some embodiments, as Figure 2 and Figure 4 shown, the air guiding structure includes two air guiding plates 2 that are movably connected to each other. Both of the two air guiding plates 2 are provided with air guiding openings. The two air guiding plates 2 are respectively movably connected to two side walls of the main body 1. The air guiding structure drives at least one air guiding opening to be switched to the air outlet 11, and the moving directions of the two air guiding plates 2 are inclined or perpendicular to each other; the two side walls of the main body 1 are spaced apart, and the air outlet 11 is formed between the two side walls of the main body 1.

[0031] It should be noted that the movable connection can be realized by many known methods such as ball joint connection, hinge connection, sliding connection, gear-gear meshing, gear-rack meshing, etc. The two movably connected air guiding plates 2 may mean that one air guiding plate 2 rotates around a fixed rotating shaft located on the other air guiding plate 2, or may mean that one air guiding plate 2 reciprocally moves along the surface of the other air guiding plate 2.

[0032] By providing two movably connected air guiding plates 2, the air guiding structure has better movement flexibility. Setting the air outlet 11 between two side walls has a larger air outlet range compared to setting it on one side wall; furthermore, the two air guiding plates 2 can better cover the air outlet 11 by moving in different directions, or expose the air outlet 11 through the air guiding openings.

[0033] In some embodiments, as Figure 3As shown, the air deflector 2 includes a deflecting part 21 and a wind blocking part 22 which are rotatably connected. The deflecting part 21 is provided with air deflecting openings. The deflecting part 21 is slidably arranged on one side wall of the main body 1. One end of the wind blocking part 22 away from the deflecting part 21 is rotatably connected to the wind blocking part 22 of another air deflector 2.

[0034] When one air deflector 2 is fixed and the other air deflector 2 moves, the wind blocking part 22 can change its position through the rotational connection with the deflecting part 21 and the wind blocking part 22 of another air deflector 2, so as to avoid the deflecting part 21 moving to the air outlet 11. When the above-mentioned deflecting part 21 moves to be hidden inside the main body 1, the wind blocking part 22 can also return to its original position to block the air outlet 11.

[0035] Exemplarily, the deflecting part 21 and the wind blocking part 22 can adopt a flat plate structure or a curved plate structure. The multiple air deflecting openings on the air deflector 2 can be circular, rectangular, fusiform and other structures. The sizes of the multiple air deflecting openings can be the same or gradually decrease along the direction away from the air outlet 11. The deflecting part 21 can adopt a multi-layer structure, and each layer is provided with air deflecting openings that communicate with each other, so as to achieve a better soft wind effect.

[0036] In some embodiments, as Figure 1 shown, when the air guiding structure moves to the closed position, the deflecting part 21 is inside the main body 1, and the wind blocking part 22 blocks the air outlet 11.

[0037] It should be noted that the air guiding structure moving to the closed position means that at this time, the air guiding structure plays a role in completely blocking the air outlet 11. In this way, the wind blocking part 22 blocks dust from entering the air conditioner indoor unit in the shutdown state, reduces the number of maintenance and cleaning times, and prolongs the service life.

[0038] In some embodiments, as Figure 2 shown, the sliding direction of the deflecting part 21 is consistent with the extending direction of the side wall where the deflecting part 21 is located. In this way, it can extend or retract into the main body 1 on the side wall more efficiently.

[0039] In some embodiments, as Figure 2 shown, the rotating shaft between the deflecting part 21 and the wind blocking part 22 is perpendicular to the sliding direction of the deflecting part 21 and parallel to the rotating shaft between the two wind blocking parts 22. When the deflecting part 21 moves, it can drive the connected wind blocking part 22 to move, and the reaction is fast and coherent.

[0040] In some embodiments, as Figure 2As shown, the air conditioner indoor unit further includes a driving device, which includes a driving gear 3. The air deflector 2 is provided with a rack 4 meshing with the driving gear 3. The driving gear 3 is used to drive the air guiding part 21 to reciprocate in a straight line direction, so as to move to the air outlet 11 or hide in the main body 1. In addition, when one air deflector 2 moves towards the air outlet 11, it can drive the other air deflector 2 to move passively and hide in the main body 1.

[0041] In some embodiments, the driving device further includes a motor, and the motor is used to drive the driving gear 3 to rotate forward or backward.

[0042] In some embodiments, as Figure 2 shown, two driving devices are provided corresponding to the two air deflectors 2 one by one. The two air deflectors 2 can be driven to move simultaneously by using the two driving devices. For example: one air deflector 2 can be driven to move to the air outlet 11, and at the same time the other air deflector 2 can be driven to move to hide in the main body 1. In this way, the air flow can be concentrated to flow out from one direction, and the other air deflector 2 moves to hide in the main body 1, which can make the air deflector 2 located at the air outlet 11 have a larger moving range.

[0043] In some embodiments, as Figure 1 shown, when the air guiding structure moves to the closed position, the two wind blocking parts 22 are respectively parallel to the two side walls of the main body 1. Visually, the two air deflectors 2 are closely matched with the main body 1, and the integration degree of the air conditioner indoor unit is higher and the appearance is more beautiful.

[0044] Further, in some embodiments, as Figure 1 shown, at least one air deflector 2 is recessed at the air outlet 11 relative to the appearance surface of the main body 1. From the appearance, it is easier for users to perceive the appearance surface of the main body 1, weakening the presence of the air guiding structure and having a better visual effect.

[0045] In some embodiments, as Figure 3 and Figure 5 shown, along the sliding direction of the air deflector 2, the length of the air guiding part 21 is greater than the length of the wind blocking part 22. The shielding area of the air guiding part 21 at the air outlet 11 is increased. When one air deflector 2 moves to the open position and the other air deflector 2 moves to the closed position, it has a larger air guiding area and air outlet direction.

[0046] In some embodiments, as Figure 3 、 Figure 4 and Figure 5 shown, the air outlet 11 is formed between the front side wall and the bottom wall of the main body 1, and the two air deflectors 2 are respectively slidably connected to the front side wall and the bottom wall of the main body 1. The air flow can flow better forward and downward, and has a longer air supply distance.

[0047] Exemplarily, the two air deflectors 2 may have the following operating states: First: As Figure 1 shown, the wind-blocking portions 22 of the two air deflectors 2 jointly block the air outlet 11. Second: As Figure 2 and Figure 3 shown, the air guiding portions 21 of the air deflectors 2 located on the front side wall of the main body 1 are located at the air outlet 11, and the air guiding portions 21 of the air deflectors 2 located on the bottom wall of the main body 1 are hidden inside the main body 1. At this time, the air flow mainly blows out from the front of the main body 1, which is more suitable for guiding the air in the refrigeration mode of the air conditioner indoor unit to deliver cold air over a long distance. Third: As Figure 4 and Figure 5 shown, the air guiding portions 21 of the air deflectors 2 located on the front side wall of the main body 1 are hidden inside the main body 1, and the air guiding portions 21 of the air deflectors 2 located on the bottom wall of the main body 1 are located at the air outlet 11. At this time, the air flow mainly blows out from below the main body 1, which is more suitable for guiding the air in the heating mode of the air conditioner indoor unit to prevent the hot air from rising. Fourth: The air guiding portions 21 of the air deflectors 2 located on the front side wall of the main body 1 are located at the air outlet 11, and the air guiding portions 21 of the air deflectors 2 located on the bottom wall of the main body 1 are located at the air outlet 11 to achieve large-angle air guiding.
