[0024] The realization of the purpose, functional features and advantages of the present application will be further described with reference to the accompanying drawings in combination with the embodiments. Specific embodiments

[0025] 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. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts belong to the scope of protection of the present application.

[0026] The embodiments of the present application provide an air guiding structure to solve the problem of the reduced comfort caused by the direct blowing of the air conditioner. The following will be described with reference to the accompanying drawings.

[0027] In the embodiments of the present application, as Figure 1 and Figure 2As shown in the figure, a wind guiding structure includes a first wind guiding plate 1 and a second wind guiding plate 2. The first wind guiding plate 1 is provided with a first air outlet 11. The second wind guiding plate 2 is arranged on the air outlet side of the first air outlet 11. At least part of the second wind guiding plate 2 protrudes from the first wind guiding plate 1 and blocks the first air outlet 11. The second wind guiding plate 2 and the first wind guiding plate 1 enclose a second air outlet 22. The second air outlet 22 is located beside the air outlet side of the first air outlet 11 and is communicated with the first air outlet 11. In this way, the air flow first blows out from the first air outlet 11, reducing the air volume. Subsequently, the blown air flow blows out from the second air outlet 22 under the guidance of the second wind guiding plate 2, and then flows in different directions, disturbing the air flow, reducing the direct current jet, so that the air flow blows towards the user from different directions, achieving a gentle wind effect and improving the user's comfort. It should be noted that at least part of the second wind guiding plate 2 blocking the first air outlet 11 may mean that the first air outlet 11 is completely blocked by the second wind guiding plate 2, or only a partial area on the first air outlet 11 is blocked by the second wind guiding plate 2, which can ensure that at least part of the air flow is blocked by the second wind guiding plate 2 and blows out from the second air outlet 22 under the guidance of the second wind guiding plate 2. When only a partial area on the first air outlet 11 is blocked by the second wind guiding plate 2, part of the air flow can continue to blow out from the first air outlet 11 to form a direct current jet, so that there is still a sense of wind in the air outlet direction of the first air outlet 11, and at the same time, it can also guide other disturbed air flows to be transported forward.

[0028] In some embodiments, as Figure 1 and Figure 2 shown, both ends of the second wind guiding plate 2 are connected to the side wall of the first air outlet 11. The second wind guiding plate 2 protrudes along the air outlet direction of the first air outlet 11 to form a protruding part 21. The protruding part 21 and the first wind guiding plate 1 enclose two second air outlets 22. In this way, both ends of the second wind guiding plate 2 are connected to the side wall of the first air outlet 11, so that the air flow blown out from the first air outlet 11 can immediately contact the second wind guiding plate 2 for wind guiding. The two second air outlets 22 can guide the diffusion in two opposite directions, having a better gentle wind effect.

[0029] In some embodiments, as Figure 2 shown, both the second wind guiding plate 2 and the first air outlet 11 are provided in multiple numbers and correspond to each other one by one. By increasing the air outlet volume of the wind guiding structure through multiple first air outlets 11 and simultaneously setting the corresponding second wind guiding plates 2 one by one, the gentle wind effect is ensured.

[0030] In some embodiments, as Figure 1As shown, a plurality of second air guide plates 2 and first air inlets 11 are respectively arranged at intervals along a first direction. The protruding portions 21 on adjacent second air guide plates 2 are arranged staggeredly, and adjacent first air inlets 11 are arranged staggeredly. The first direction is perpendicular or inclined to the direction connecting the two ends of the second air guide plate 2. It should be noted that the first direction can refer to the length direction or width direction of the second air guide plate 2, or can be inclined to the length and width directions of the second air guide plate 2. Preferably, the first direction is the width direction of the second air guide plate 2, and the direction of the two ends of the second air guide plate 2 is perpendicular to the first direction, that is, the direction of the two ends of the second air guide plate 2 is the length direction of the first air guide plate 1.

[0031] Furthermore, in some embodiments, a plurality of second air guide plates 2 and first air inlets 11 are respectively arranged at intervals along the direction connecting the two ends of the second air guide plate 2. Exemplarily, the direction of the two ends of the second air guide plate 2 is perpendicular to the first direction, and the two second air outlets 22 formed by the protruding portion 21 and the first air guide plate 1 are arranged along the first direction and are respectively located on both sides of the second air guide plate 2. In this way, the air output in the first direction can be increased.

[0032] In some embodiments, as Figure 1 shown, the second air guide plate 2 includes a plurality of protruding portions 21, and the plurality of protruding portions 21 are sequentially connected along the direction of the two ends of the second air guide plate 2 to form a wave structure. It should be noted that the wave structure means that the cross-section of a protruding portion 21 can be curved or arc-shaped. When the cross-section is curved, the two ends of the protruding portion 21 are wave troughs to connect the side walls of the first air inlet 11, and the middle of the protruding portion 21 is a wave peak. In this way, when a plurality of protruding portions 21 are connected together, a wave structure is formed.

[0033] In some specific embodiments, as Figure 1 shown, the plurality of protruding portions 21 included in the second air guide plate 2 are integrally formed. In this way, the plurality of protruding portions 21 have a better soft air effect, and the integrally formed design is beneficial to improving the assembly efficiency.

[0034] In some embodiments, as Figure 1 and Figure 2 shown, the first air inlet 11 includes a plurality of air dispersion small openings 111 sequentially arranged at intervals along the direction of the two ends of the second air guide plate 2. The plurality of protruding portions 21 correspond to the plurality of air dispersion small openings 111 one by one, and the two ends of the protruding portion 21 are respectively connected to the side walls of the air dispersion small openings 111. In this way, through the plurality of air dispersion small openings 111, it can better correspond to the plurality of protruding portions 21 to improve the soft air effect.

[0035] In some embodiments, as Figure 2As shown, the width of the small air-diffusing opening 111 gradually decreases towards both ends close to the small air-diffusing opening 111, and the width of the convex portion 21 gradually decreases towards both ends close to the small air-diffusing opening 111. It should be noted that when the air flow passes through the first air guide opening 11, it is concentrated and blown out from the middle area of the first air guide opening 11, and the air volume on the air outlet side of the first air guide opening 11 decreases from the middle of the first air guide opening 11 towards both ends. Based on this, the small air-diffusing opening 111 and the convex portion 21 are set to the above structure, that is, the side walls of the small air-diffusing opening 111 and both sides of the convex portion 21 are arc-shaped, which can better adapt to the air volume distribution on the air outlet side of the first air guide opening 11, and further improve the turbulence effect in the area with a larger air outlet volume.

[0036] In some embodiments, as Figure 1 and Figure 3 shown, the width of the convex portion 21 is smaller than the width of the small air-diffusing opening 111. In this way, the convex portion 21 blocks part of the small air-diffusing opening 111 to ensure the blowing of a part of the direct jet flow, which is convenient for guiding the air flow in other directions to be transported forward. Exemplarily, the width L1 of the small air-diffusing opening 111 needs to satisfy 9 mm ≤ L1 ≤ 15 mm, the width L2 of the convex portion 21 needs to satisfy 3 mm ≤ L2 ≤ 9 mm, the height L3 of the convex portion 21 protruding needs to satisfy 0 mm < L3 < 7 mm, and 6 mm ≤ (L1 - L2) ≤ 10 mm.

[0037] In some embodiments, as Figure 3 shown, the first air guide plate 1 is an arc-shaped plate. It should be noted that the first air guide plate 1 being an arc-shaped plate can mean that the projection of the first air guide plate 1 along its own width direction is arc-shaped, or it can mean that the projection of the first air guide plate 1 along its own length direction is arc-shaped. In this way, on the one hand, the impact force of the air flow on the second air guide plate 2 is optimized, and on the other hand, the diffusion range of the air flow after passing through the first air guide opening 11 is increased.

[0038] In some embodiments, a rotating shaft 12 is provided at both ends of the first air guide plate 1, and a limiting portion 121 is provided on the circumferential side of the rotating shaft 12 to achieve circumferential limiting of the rotating shaft 12.

[0039] In some embodiments, as Figure 4 and Figure 5 shown, a convex mounting seat 13 is provided on the side of the first air guide plate 1 facing away from the second air guide plate 2. The mounting seat 13 is located in the middle of the first air guide plate 1, and a mounting hole 131 penetrating along the length direction of the first air guide plate 1 is provided on the mounting seat 13. The mounting hole 131 is used for the positioning pin 33 at the air outlet 31 of the air conditioner indoor unit 3 to pass through to achieve the installation and fixation of the air guide structure. In this way, by moving the air guide structure along the length direction of the first air guide plate 1, the disassembly and assembly can be easily completed, which is convenient for the daily cleaning and maintenance of the air guide structure.

[0040] In some embodiments, asFigure 6 As shown, the air guiding structure is configured to be disposed near the inner side of the air outlet 31 of the air conditioner indoor unit 3. The air conditioner indoor unit 3 is rotatably connected with an outer second air guiding plate 32, and the outer second air guiding plate 32 is disposed outside the air outlet 31 of the air conditioner indoor unit 3. When the air conditioner indoor unit 3 is turned off, the outer second air guiding plate 32 is closed to hide the air guiding structure. In this way, by providing the first air guiding opening 11 and the second air guiding opening 22 on the air guiding structure, the problem that the outer second air guiding plate 32 is difficult to clean due to dust accumulation caused by opening holes in the outer second air guiding plate 32 in the related art is solved.

[0041] The embodiment of the present application further provides an air conditioner indoor unit 3, as Figure 5 and Figure 6 shown. The air conditioner indoor unit 3 includes the above-mentioned air guiding structure and the outer second air guiding plate 32. The specific structure of the air guiding structure refers to the above-mentioned embodiment. Since the air conditioner indoor unit 3 of the present application adopts all the technical solutions of the above-mentioned all embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, and will not be elaborated one by one here. Among them, the air conditioner indoor unit 3 is provided with an air outlet 31, and a positioning pin 33 is provided on the side wall of the air outlet 31. The air guiding structure is located inside the air outlet 31, and a positioning pin 33 is provided on the side wall of the air outlet 31 for passing through the mounting hole 131 of the air guiding structure. The outer second air guiding plate 32 is disposed near the outside of the air outlet 31, and the air guiding structure is disposed near the inside of the air outlet 31. It can be understood that when the air conditioner indoor unit 3 is closed, the outer second air guiding plate 32 blocks the air guiding structure.
