[0052] The principles and features of the present application are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present application and are not used to limit the scope of the present application.

[0053] like Figure 1-Figure 6 As shown, an embodiment of the present application provides an indoor unit of an air conditioner, including a casing 1 and an air guide plate assembly.

[0054] The housing 1 has an air outlet 11. The housing 1 also has an air inlet 14 and an air duct 8, the two ends of the air duct 8 are respectively connected to the air inlet 14 and the air outlet 11, and a wind wheel 6 and an indoor heat exchanger 5 are arranged in the air duct 8, and the indoor heat exchanger 5 can be located on the side of the wind wheel 6 close to the air inlet 14. Under the action of the wind wheel 6, the indoor air can enter the air duct 8 from the air inlet 14, and flow through the indoor heat exchanger 5 to exchange heat with the indoor heat exchanger 5, and the air after heat exchange can be discharged back to the room from the air outlet 11.

[0055] The air guide plate assembly can be used to cover or open the air outlet 11 so as to control the air outflow at the air outlet 11. The air guide plate assembly can include an outer air guide plate 2 and an inner air guide plate 3, both of which can be rotatably mounted to the housing 1, and both of which are arc-shaped plates protruding to the outside of the housing 1, and the outer air guide plate 2 is provided with a plurality of first air dispersion holes 21, and the inner air guide plate 3 is located on the inner side of the outer air guide plate 2.

[0056] The indoor unit of the air conditioner has a windless cooling mode. Figure 1 and Figure 2 As shown, in the windless cooling mode, the outer air guide plate 2 at least covers the upper part of the air outlet 11, the first end 32 of the inner air guide plate 3 is close to the lower end of the air outlet 11, and the second end 33 of the inner air guide plate 3 coincides with the lower part of the outer air guide plate 2.

[0057] When the indoor unit of the air conditioner of the embodiment of the present application is in the windless cooling mode, Figure 1 and Figure 2 As shown, the outer air guide plate 2 at least covers the upper part of the air outlet 11, the first end 32 of the inner air guide plate 3 is close to the lower end of the air outlet 11, and the second end 33 of the inner air guide plate 3 overlaps with the lower part of the outer air guide plate 2. In this way, the inner air guide plate 3 and the outer air guide plate 2 cooperate to cover the air outlet 11 substantially in its entirety. After the indoor air enters the air duct 8, it can exchange heat with the indoor heat exchanger 5 for cooling. The cooled cold air can flow to the air outlet 11 and blow out from the first air dispersion hole 21 of the outer air guide plate 2. Through the first air dispersion hole 21, the blowing feeling of the air outlet can be weakened, and then the air outlet without wind feeling can be realized, which improves the comfort of blowing.

[0058] Since the outer air guide plate 2 is an arc-shaped plate, compared with the straight air guide plate in the prior art, when the size of the air outlet 11 remains unchanged, the area of ​​the arc-shaped plate is larger than that of the straight air guide plate, thereby increasing the number of the first air dispersion holes 21 on the outer air guide plate 2 and increasing the total ventilation area of ​​the multiple first air dispersion holes 21, which is beneficial to achieving faster cooling while ensuring no wind outlet in the windless cooling mode, and avoiding the problem of users feeling stuffy due to insufficient cooling.

[0059] In the windless cooling mode, the first end 32 of the inner air guide plate 3 is close to the lower end of the air outlet 11, and the second end 33 of the inner air guide plate 3 overlaps with the lower part of the outer air guide plate 2 to shield the lower part of the outer air guide plate 2. By shielding the lower part of the outer air guide plate 2 by the inner air guide plate 3, the amount of cold air blown downward in the windless cooling mode can be reduced, so as to avoid the problem that the cold air blown downward is unfriendly to the user when the air conditioner indoor unit is installed directly above the bed, so that the air conditioner indoor unit of the embodiment of the present application can be installed directly above the bed.

[0060] In the air guide plate assembly, the inner air guide plate 3 and the outer air guide plate 2 can both be arc-shaped plates, and the rotation centers 4 of the outer air guide plate 2 and the inner air guide plate 3 can coincide, so that the inner air guide plate 3 and the outer air guide plate 2 will not interfere with each other during rotation, and it is beneficial to reduce the gap between the inner air guide plate 3 and the outer air guide plate 2, so as to avoid the problem of air leakage from the gap between the inner air guide plate 3 and the outer air guide plate 2 as much as possible.

[0061] Therefore, the indoor unit of the air conditioner in the embodiment of the present application can ensure the cooling capacity in the windless cooling mode by setting the arc-shaped inner air guide plate 3 and the outer air guide plate 2, and avoid the problem of cold air blowing downwards being unfriendly to users, thereby improving the performance of the indoor unit of the air conditioner.

[0062] In some exemplary embodiments, the windless cooling mode includes a first windless cooling mode. Figure 1 As shown, in the first windless cooling mode, the first end 32 of the inner air guide plate 3 extends into the lower end of the air outlet 11 , and the second end 33 of the inner air guide plate 3 overlaps with the lower part of the outer air guide plate 2 .

[0063] like Figure 1 As shown, in the first windless cooling mode, the first end 22 of the outer air guide plate 2 extends into the upper end of the air outlet 11, and an air outlet gap 15 is provided between the second end 23 of the outer air guide plate 2 and the lower end of the air outlet 11, and the inner air guide plate 3 blocks the air outlet gap 15.

[0064] In the first windless cooling mode, the outer air guide plate 2 is close to the upper part of the air outlet 11, and the first end 22 of the outer air guide plate 2 extends into the upper end of the air outlet 11, and there is an air outlet gap 15 between the second end 23 of the outer air guide plate 2 and the lower end of the air outlet 11; the inner air guide plate 3 is close to the lower part of the air outlet 11, and the first end 32 of the inner air guide plate 3 extends into the lower end of the air outlet 11, and the second end 33 of the inner air guide plate 3 coincides with the lower part of the outer air guide plate 2, so that the inner air guide plate 3 can, on the one hand, block the air outlet gap 15 between the second end 23 of the outer air guide plate 2 and the lower end of the air outlet 11, and on the other hand, can block the lower part of the outer air guide plate 2 to reduce / avoid the problem of cold leakage in the lower part.

[0065] In the first windless cooling mode, since the first end 32 of the inner air guide plate 3 extends into the lower end of the air outlet 11, the overlapping area between the inner air guide plate 3 and the outer air guide plate 2 is relatively small, that is, the inner air guide plate 3 blocks a relatively small area of ​​the outer air guide plate 2. At this time, the indoor unit of the air conditioner as a whole can rely on the first air dissipation holes 21 of the outer air guide plate 2 to achieve maximum cooling, so as to achieve a large amount of cooling without a sense of wind, and avoid the problem of insufficient cooling causing the user to feel stuffy.

[0066] In some exemplary embodiments, the windless cooling mode further includes a second windless cooling mode. Figure 2 As shown, in the second windless cooling mode, the inner air guide plate 3 is located outside the air outlet 11 and covers the lower part of the air outlet 11, and the first end 32 of the inner air guide plate 3 is close to the lower end of the air outlet 11, and the second end 33 of the inner air guide plate 3 coincides with the lower part of the outer air guide plate 2.

[0067] like Figure 2 As shown, in the second windless cooling mode, the outer air guide plate 2 is located outside the air outlet 11, and the first end 22 of the outer air guide plate 2 is close to the upper end of the air outlet 11, the second end 23 of the outer air guide plate 2 is close to the lower end of the air outlet 11, and the first end 32 of the inner air guide plate 3 is flush with the second end 23 of the outer air guide plate 2 or protrudes from the second end 23 of the outer air guide plate 2.

[0068] In the second windless cooling mode, the outer air guide plate 2 is located as a whole outside the air outlet 11, and the first end 22 and the second end of the outer air guide plate 2 are respectively close to the upper end and the lower end of the air outlet 11, so that the outer air guide plate 2 as a whole can basically cover the air outlet 11; the inner air guide plate 3 is close to the lower part of the air outlet 11, and the inner air guide plate 3 is located as a whole outside the air outlet 11, wherein the first end 32 of the inner air guide plate 3 is close to the lower end of the air outlet 11, and the first end 32 of the inner air guide plate 3 can be flush with the second end 23 of the outer air guide plate 2 or protrude from the second end 23 of the outer air guide plate 2, and the second end 33 of the inner air guide plate 3 coincides with the lower part of the outer air guide plate 2, so that the inner air guide plate 3 can block the lower part of the outer air guide plate 2 to reduce / avoid the problem of cold leakage in the lower part.

[0069] In the second windless cooling mode, the inner air guide plate 3 is basically entirely overlapped with the lower portion of the outer air guide plate 2, which can greatly reduce the effect of cold leakage in the lower portion in the second windless cooling mode.

[0070] When the indoor unit of the air conditioner is in the off state, the positions of the outer air guide plate 2 and the inner air guide plate 3 may be the same as the positions of the outer air guide plate 2 and the inner air guide plate 3 in the second windless cooling mode.

[0071] In some exemplary embodiments, in the second windless cooling mode, the area of ​​the overlapped portion of the inner air guide plate 3 and the outer air guide plate 2 (eg Figure 2) is larger than the area of ​​the overlapped portion of the inner air guide plate 3 and the outer air guide plate 2 in the first windless cooling mode (as shown in Figure 1 shown).

[0072] In the first windless cooling mode, the overlapped area of ​​the inner air guide plate 3 and the outer air guide plate 2 is small, and in the second windless cooling mode, the overlapped area of ​​the inner air guide plate 3 and the outer air guide plate 2 is large. Therefore, in the first windless cooling mode, the first air dissipation holes 21 on the outer air guide plate 2 that are not blocked by the inner air guide plate 3 can be used to dissipate the cooling to the maximum extent, so as to achieve a large amount of cooling without a sense of wind; in the second windless cooling mode, the first air dissipation holes 21 on the outer air guide plate 2 that are not blocked by the inner air guide plate 3 can be used to dissipate the cooling to a lesser extent. The first windless cooling mode and the second windless cooling mode can be used together to meet different user needs.

[0073] In some exemplary embodiments, the indoor unit of the air conditioner has a normal cooling mode. Figure 3 As shown, in the conventional cooling mode, there is an air outlet gap 15 between the first end 22 of the outer air guide plate 2 and the upper end of the air outlet 11, the second end 23 of the outer air guide plate 2 extends into the lower end of the air outlet 11, and the inner air guide plate 3 overlaps with the portion of the outer air guide plate 2 located outside the air outlet 11, and the overlapping portion is close to the lower end of the air outlet 11.

[0074] In the conventional cooling mode, the second end 23 of the outer air guide plate 2 extends into the lower end of the air outlet 11, and an air outlet gap 15 is provided between the first end 22 of the outer air guide plate 2 and the upper end of the air outlet 11, so that the outer air guide plate 2 is close to the lower part of the air outlet 11, and the upper part of the air outlet 11 is opened for air outlet; the inner air guide plate 3 overlaps with the portion of the outer air guide plate 2 located outside the air outlet 11, and the overlapping portion is close to the lower end of the air outlet 11, so that the inner air guide plate 3 can block the portion of the outer air guide plate 2 located outside the air outlet 11 and close to the lower part, so as to avoid cold air from being blown out from the first air dispersion hole 21 on the portion of the outer air guide plate 2 located outside the air outlet 11 and close to the lower part, thereby reducing air leakage.

[0075] In the conventional cooling mode, the outer air guide plate 2 can guide the air outward in the upper front direction, so that the cold air can be blown out from the air outlet gap 15 between the first end 22 of the outer air guide plate 2 and the upper end of the air outlet 11, and flow forward and upward; the inner air guide plate 3 overlaps with the outer air guide plate 2 at the lower part, reducing the air leakage of the first air dispersion hole 21 at the lower part of the outer air guide plate 2, which is beneficial to increase the air guiding distance of the outer air guide plate 2 and improve the cooling effect.

[0076] In some exemplary embodiments, Figure 3As shown, in the conventional cooling mode, the end of the first end 22 of the outer air guide plate 2 is set to be lower than the rotation center 4 of the outer air guide plate 2, such as: the end of the first end 22 of the outer air guide plate 2 can be slightly lower than the rotation center 4 of the outer air guide plate 2, so that the outer air guide plate 2 can guide the air forward and upward, and the cold air can be blown out forward and upward, which helps to improve the cooling effect.

[0077] In some exemplary embodiments, Figure 3 As shown, in the conventional cooling mode, the inner air guide plate 3 is located outside the air outlet 11 , and the first end 32 of the inner air guide plate 3 is close to the lower end of the air outlet 11 , and the second end 33 of the inner air guide plate 3 does not protrude from the first end 22 of the outer air guide plate 2 .

[0078] In the conventional cooling mode, the inner air guide plate 3 is located outside the air outlet 11, and the first end 32 of the inner air guide plate 3 is close to the lower end of the air outlet 11. Compared with the first end 32 of the inner air guide plate 3 extending into the lower end of the air outlet 11, the overlapping area between the inner air guide plate 3 and the outer air guide plate 2 in the embodiment of the present application is larger, which can minimize the air leakage of the first air dispersion hole 21 at the lower part of the outer air guide plate 2, which is beneficial to increase the air guiding distance of the outer air guide plate 2 and improve the cooling effect; the second end 33 of the inner air guide plate 3 does not protrude from the first end 22 of the outer air guide plate 2, so that the second end 33 of the inner air guide plate 3 is also lower than the rotation center 4 of the outer air guide plate 2, thereby preventing the inner air guide plate 3 from affecting the cold air from blowing forward and upward.

[0079] In some exemplary embodiments, Figure 3 As shown, a first curved wall 13 is provided in the housing 1, and the first curved wall 13 forms the lower wall of the air outlet 11. The housing 1 may include a face frame, and the first curved wall 13 may be fixed in the face frame, or the first curved wall 13 may be integrally formed inside the face frame.

[0080] In the normal cooling mode, the end of the second end 23 of the outer air guide plate 2 is flush with an end of the first arc-shaped wall 13 on the air outlet side away from the air outlet 11 .

[0081] The first curved wall 13 may be an arc-shaped wall, and the curvature of the first curved wall 13 may be adapted to the curvature of the outer air guide plate 2, so that in the conventional cooling mode, when the end of the second end 23 of the outer air guide plate 2 is flush with an end of the first curved wall 13 on the air outlet side away from the air outlet 11 (the concave corner of the face frame), the outer air guide plate 2 can smoothly guide the cold air flowing to the air outlet 11. In addition, the arrangement of the first curved wall 13 will not interfere with the rotation of the outer air guide plate 2.

[0082] In some exemplary embodiments, the indoor unit of the air conditioner has a conventional heating mode. Figure 4As shown, in the conventional heating mode, the first end 22 of the outer air guide plate 2 extends into the upper end of the air outlet 11, and an air outlet gap 15 is provided between the second end 23 of the outer air guide plate 2 and the lower end of the air outlet 11, and the inner air guide plate 3 overlaps with the portion of the outer air guide plate 2 located outside the air outlet 11, and the overlapping portion is close to the upper end of the air outlet 11.

[0083] In the conventional heating mode, the first end 22 of the outer air guide plate 2 extends into the upper end of the air outlet 11, and an air outlet gap 15 is provided between the second end 23 of the outer air guide plate 2 and the lower end of the air outlet 11, so that the outer air guide plate 2 is close to the upper part of the air outlet 11, and the lower part of the air outlet 11 is opened for air outlet; the inner air guide plate 3 overlaps with the portion of the outer air guide plate 2 located outside the air outlet 11, and the overlapping portion is close to the upper end of the air outlet 11, so that the inner air guide plate 3 can block the portion of the outer air guide plate 2 located outside the air outlet 11 and close to the upper part, so as to avoid hot air from being blown out from the first air dispersion hole 21 on the portion of the outer air guide plate 2 located outside the air outlet 11 and close to the upper part, thereby reducing air leakage.

[0084] In the conventional heating mode, the outer air guide plate 2 guides the air downward, so that the hot air can be blown out from the air outlet gap 15 between the second end 23 of the outer air guide plate 2 and the lower end of the air outlet 11, and flow downward; the inner air guide plate 3 overlaps with the outer air guide plate 2 at the upper part, reducing the air leakage of the first air dissipation hole 21 at the upper part of the outer air guide plate 2, which is beneficial to enhance the heat conduction and air compression effect of the outer air guide plate 2 and improve the heating effect.

[0085] In some exemplary embodiments, Figure 4 As shown, in the conventional heating mode, the second end 23 of the outer air guide plate 2 is not higher than the rotation center 4 of the outer air guide plate 2, such as: the second end 23 of the outer air guide plate 2 can be at the same horizontal height as the rotation center 4 of the outer air guide plate 2, or the second end 23 of the outer air guide plate 2 can be slightly lower than the rotation center 4 of the outer air guide plate 2, so that the outer air guide plate 2 can guide the air downward, and the hot air can be blown out downward, which helps to improve the heating effect.

[0086] In some exemplary embodiments, Figure 4 As shown, in the conventional heating mode, the first end 32 of the inner air guide plate 3 is flush with the second end 23 of the outer air guide plate 2 , and the second end 33 of the inner air guide plate 3 extends into the upper end of the air outlet 11 .

[0087] In the conventional heating mode, the second end 33 of the inner air guide plate 3 can extend into the upper end of the air outlet 11, and the first end 32 of the inner air guide plate 3 can be flush with the second end 23 of the outer air guide plate 2, so that the first end 32 of the inner air guide plate 3 does not protrude from the second end 23 of the outer air guide plate 2, and the first end 32 of the inner air guide plate 3 is also lower than the rotation center 4 of the outer air guide plate 2. In this way, the inner air guide plate 3 can completely block the part of the outer air guide plate 2 located outside the air outlet 11, minimize the air leakage of the first air dissipation hole 21 on the outer air guide plate 2, and help improve the heating effect.

[0088] In some exemplary embodiments, Figure 4 As shown, a second arc-shaped wall 14 is provided in the housing 1, and the second arc-shaped wall 14 forms the upper wall of the air outlet 11. The second arc-shaped wall 14 can be fixed in the face frame of the housing 1, or the second arc-shaped wall 14 can be integrally formed inside the face frame.

[0089] In the normal heating mode, the end of the first end 22 of the outer air guide plate 2 is flush with an end of the second arc-shaped wall 14 on the air outlet side away from the air outlet 11 .

[0090] The second curved wall 14 may be an arc-shaped wall, and the curvature of the second curved wall 14 may be adapted to the curvature of the outer air guide plate 2, so that in the conventional heating mode, when the end of the first end 22 of the outer air guide plate 2 is substantially flush with an end of the second curved wall 14 on the air outlet side away from the air outlet 11 (the corner of the concave surface of the volute tongue of the face frame), the outer air guide plate 2 may smoothly guide the hot air flowing to the air outlet 11. In addition, the provision of the second curved wall 14 will not interfere with the rotation of the outer air guide plate 2.

[0091] In some exemplary embodiments, the indoor unit of the air conditioner has a heating windless mode. Figure 5 As shown, in the heating windless mode, the outer air guide plate 2 blocks the lower part of the air outlet 11, the inner air guide plate 3 blocks the upper part of the air outlet 11, and a portion of the outer air guide plate 2 and the inner air guide plate 3 overlap.

[0092] In the heating windless mode, the outer air guide plate 2 is close to the lower part of the air outlet 11, and the inner air guide plate 3 is close to the upper part of the air outlet 11. The inner air guide plate 3 can be used to realize compressed air, so that the hot air can be diffused through the first air diffusion holes 21 of the outer air guide plate 2, and the heating windless feeling is realized. In the heating windless mode, a part of the outer air guide plate 2 and the inner air guide plate 3 overlap to minimize the air leakage between the outer air guide plate 2 and the inner air guide plate 3.

[0093] Through the cooperation of the inner air guide plate 3 and the outer air guide plate 2, the heating of the indoor unit of the air conditioner is achieved without wind.

[0094] In some exemplary embodiments, Figure 5As shown, in the heating windless mode, the second end 23 of the outer air guide plate 2 extends into the lower end of the air outlet 11, and an air outlet gap 15 is provided between the first end 22 of the outer air guide plate 2 and the upper end of the air outlet 11, the first end 32 of the inner air guide plate 3 coincides with the first end 22 of the outer air guide plate 2, and the second end 33 of the inner air guide plate 3 extends into the upper end of the air outlet 11.

[0095] In the heating windless mode, the second end 23 of the outer air guide plate 2 extends into the lower end of the air outlet 11, the second end 33 of the inner air guide plate 3 extends into the upper end of the air outlet 11, and the first end 32 of the inner air guide plate 3 coincides with the first end 22 of the outer air guide plate 2, so that the air outlet gap 15 between the first end 22 of the outer air guide plate 2 and the upper end of the air outlet 11 is blocked by the inner air guide plate 3, so as to minimize air leakage from the gap between the outer air guide plate 2 and the lower end of the air outlet 11, the gap between the inner air guide plate 3 and the upper end of the air outlet 11, and the gap between the air guide plate and the inner air guide plate 3.

[0096] In some exemplary embodiments, Figure 1 As shown, the central angle A of the outer air guide plate 2 is greater than the central angle B of the inner air guide plate 3, that is, A>B.

[0097] In the air guide plate assembly, the central angle A of the outer air guide plate 2 (the curvature of the outer air guide plate 2) is relatively large, which can basically cover the entire air outlet 11 in the second windless cooling mode or the shutdown state; the central angle B of the inner air guide plate 3 (the curvature of the inner air guide plate 3) is relatively small, which plays a role in coordinating the air guiding.

[0098] In some exemplary embodiments, the central angle A of the outer air guide plate 2 is 120° to 150°, that is, 120°≤A≤150°.

[0099] For the outer air guide plate 2, the corresponding central angle (radian of the outer air guide plate 2) A needs to meet the following requirements:

[0100] 1. In Figure 2 In the second windless cooling mode shown, the outer air guide plate 2 should cover the air outlet 11 as completely as possible;

[0101] 2. In Figure 3 In the conventional cooling mode shown, the end of the second end 23 of the outer air guide plate 2 is flush with an end of the first arc-shaped wall 13 on the air outlet side away from the air outlet 11 (the concave corner of the face frame), and the first end 22 of the outer air guide plate 2 cannot block most of the air outlet (e.g., the end of the first end 22 of the outer air guide plate 2 may be near the rotation center 4 of the outer air guide plate 2, for example, the end of the first end 22 of the outer air guide plate 2 may be substantially at the same level as the rotation center 4 of the outer air guide plate 2, or may be below the rotation center 4 of the outer air guide plate 2);

[0102] 3. In Figure 4In the conventional heating mode shown, the end of the first end 22 of the outer air guide plate 2 is approximately flush with an end of the second curved wall 14 on the air outlet side away from the air outlet 11 (the corner of the concave surface of the volute tongue of the face frame), and the end of the second end 23 of the outer air guide plate 2 may be near the rotation center 4 of the outer air guide plate 2 (e.g., the end of the second end 23 of the outer air guide plate 2 may be substantially at the same horizontal height as the rotation center 4 of the outer air guide plate 2 (at the end of the second end 23 of the outer air guide plate 2, the tangent of the outer wall surface or the inner wall surface of the outer air guide plate 2 may be substantially vertical), or may be below the rotation center 4 of the outer air guide plate 2).

[0103] Based on the above requirements, the central angle of the outer air guide plate 2 (the curvature of the outer air guide plate 2) A can be set between 120° and 150°, such as: the central angle of the outer air guide plate 2 (the curvature of the outer air guide plate 2) A can be set to 120°, 125°, 130°, 135°, 140°, 145°, 150°, etc.

[0104] In some exemplary embodiments, the central angle B of the inner air guide plate 3 (the curvature of the inner air guide plate 3 ) is less than or equal to half of the central angle A of the outer air guide plate 2 , that is, B≤A / 2.

[0105] The inner air guide plate 3 cooperates with the outer air guide plate 2 to guide the air, and not only realizes the windless air discharge in the first windless cooling mode, the second windless cooling mode and the windless heating mode, but also realizes the upward air guidance in the conventional cooling mode and the downward pressure in the conventional heating mode. Therefore, the central angle B of the inner air guide plate 3 is ≤ half of the arc of the outer air guide plate 2, and the above functions can be realized.

[0106] In some exemplary embodiments, Figure 1 and Figure 2 As shown, the sum of the central angle A of the outer air guide plate 2 and the central angle B of the inner air guide plate 3 is not less than the angle C formed by the line connecting the upper and lower ends of the air outlet 11 and the rotation center 4, that is, A+B≥C, so that the outer air guide plate 2 and the inner air guide plate 3 can cooperate to completely cover the air outlet 11, so as to achieve the windless air outlet in the first windless cooling mode, the second windless cooling mode and the windless heating mode. Therefore, the central angle B of the inner air guide plate 3 can be set to be greater than 30°, that is, the value range of the central angle B of the inner air guide plate 3 can be: 30°<B≤A / 2.

[0107] In some exemplary embodiments, Figure 1-Figure 5 As shown, the inner air guide plate 3 is provided with a plurality of second air dispersion holes 31. The ventilation cross-sectional area of ​​the second air dispersion holes 31 is smaller than the ventilation cross-sectional area of ​​the first air dispersion holes 21, and / or the spacing between adjacent second air dispersion holes 31 is larger than the spacing between adjacent first air dispersion holes 21.

[0108] The ventilation cross-sectional area of ​​the second air dispersion holes 31 of the inner air guide plate 3 is smaller than the ventilation cross-sectional area of ​​the first air dispersion holes 21 of the outer air guide plate 2, so that the aperture (or equivalent aperture) of the second air dispersion holes 31 is smaller; the spacing between adjacent second air dispersion holes 31 is larger than the spacing between adjacent first air dispersion holes 21. Therefore, compared with the first air dispersion holes 21 of the outer air guide plate 2, the second air dispersion holes 31 of the inner air guide plate 3 adopt a fine micropore design. In the conventional cooling mode or the conventional heating mode, when the inner air guide plate 3 is used to guide or compress the air, the second air dispersion holes 31 will not leak too much air, so that the inner air guide plate 3 has a long air guiding distance or a good air compression effect.

[0109] Of course, the inner air guide plate 3 may not be provided with the second air dispersion holes 31, that is, the inner air guide plate 3 may be a non-porous plate without air dispersion holes, wherein the "hole" in the "non-porous plate" here refers to the air dispersion holes. Therefore, the inner air guide plate 3 may not be provided with air dispersion holes, but may be provided with holes with other functions, such as: installation holes, fixing holes, etc.

[0110] In some exemplary embodiments, Figure 6 As shown, the air outlet direction of the first air dispersion hole 21 (as shown by arrow D1) is deflected upward relative to a first connecting line L1 passing through the center of the air inlet side of the first air dispersion hole 21 and the rotation center 4 of the outer air guide plate 2, and the air outlet direction of the second air dispersion hole 31 (as shown by arrow D2) is deflected downward relative to a second connecting line L2 passing through the center of the air inlet side of the second air dispersion hole 31 and the rotation center 4 of the inner air guide plate 3.

[0111] The air outlet direction D1 of the first air dispersing hole 21 is deflected upward relative to a first connecting line L1 between the center of the air inlet side of the first air dispersing hole 21 and the rotation center 4 of the outer air guide plate 2, so that in the first windless cooling mode, the second windless cooling mode and the conventional cooling mode, the cold air blown out through the first air dispersing hole 21 can flow upward to improve the cooling effect.

[0112] The air outlet direction D2 of the second air dispersion hole 31 is deflected downward relative to the second connecting line L2 passing through the center of the air inlet side of the second air dispersion hole 31 and the rotation center 4 of the inner air guide plate 3. The deflection directions of the first air dispersion hole 21 and the second air dispersion hole 31 are opposite, so that when the inner air guide plate 3 and the outer air guide plate 2 overlap, the airflow flowing out of the second air dispersion hole 31 is not easy to smoothly enter the first air dispersion hole 21, ensuring the wind blocking effect of the cooperation between the inner air guide plate 3 and the outer air guide plate 2, which is beneficial to reducing the air leakage in the first no-wind cooling mode, the second no-wind cooling mode and the no-wind heating mode, and is beneficial to ensuring the upward air guiding effect in the conventional cooling mode and the downward air pressing effect in the conventional heating mode.

[0113] During manufacturing, the outer draft direction of the outer air guide plate 2 is upward along the air outlet direction, and the outer draft direction of the inner air guide plate 3 is downward along the air outlet direction.

[0114] In some exemplary embodiments, Figure 6 As shown, the first air diffusion holes 21 and the second air diffusion holes 31 are arranged alternately.

[0115] The first air diffusion holes 21 and the second air diffusion holes 31 are arranged in a staggered manner, so that the airflow flowing out of the second air diffusion holes 31 is not easy to smoothly enter the first air diffusion holes 21, thereby ensuring the wind blocking effect of the inner air guide plate 3 and the outer air guide plate 2, which is beneficial to reducing air leakage in the first windless cooling mode, the second windless cooling mode and the windless heating mode, and is beneficial to ensuring the upward air guiding effect in the conventional cooling mode and the downward air pressing effect in the conventional heating mode.

[0116] In some exemplary embodiments, the air conditioner indoor unit further includes a first driving mechanism and a second driving mechanism.

[0117] The first driving mechanism is installed in the housing 1, connected to the outer air guide plate 2, and configured to drive the outer air guide plate 2 to rotate. The first driving mechanism can be connected to both ends of the outer air guide plate 2, so that both ends of the outer air guide plate 2 are evenly stressed. The first driving mechanism may include a first motor and a first transmission assembly, and the first motor may drive the outer air guide plate 2 to rotate through the first transmission assembly.

[0118] The second driving mechanism is installed in the housing 1, connected to the inner air guide plate 3, and configured to drive the inner air guide plate 3 to rotate. The second driving mechanism can be connected to both ends of the inner air guide plate 3, so that both ends of the inner air guide plate 3 are evenly stressed. The second driving mechanism can include a second motor and a second transmission assembly, and the second motor can drive the inner air guide plate 3 to rotate through the second transmission assembly.

[0119] In some exemplary embodiments, Figure 1-Figure 5 As shown, the indoor unit of the air conditioner further comprises a swing blade 7, which is arranged in the air duct 8 and close to the air outlet 11. The swing blade 7 can swing left and right or up and down to guide the air.

[0120] In summary, the air guide plate assembly of the indoor unit of the air conditioner in the embodiment of the present application is an inner and outer double-layer structure mainly composed of an inner air guide plate 3 and an outer air guide plate 2. The outer air guide plate 2 can adopt a first air dispersion hole 21 formed by conventional non-wind-sensing micropores, and the inner air guide plate 3 can adopt a hole-free (air dispersion hole) design, or can adopt a second air dispersion hole 31 formed by fine holes, and the inner air guide plate 3 can cooperate with the outer air guide plate 2 to block the gap for air leakage.

[0121] The upper and lower walls of the air outlet 11 of the indoor unit of the air conditioner adopt a first arc-shaped wall 13 and a second arc-shaped wall 14, so that the cross section of the air outlet 11 is circular to match the shape of the air guide plate assembly.

[0122] The inner air guide plate 3 and the outer air guide plate 2 use the same rotation center 4 (i.e., the rotation centers 4 of the inner air guide plate 3 and the outer air guide plate 2 coincide with each other), and various functional modes of the indoor unit of the air conditioner can be realized through the movement coordination of the two. Among them, a variety of windless refrigeration modes (such as: the first windless refrigeration mode and the second windless refrigeration mode, etc.) can be set according to the windless refrigeration speed; in the conventional refrigeration mode, the inner air guide plate 3 blocks the first air dispersion hole 21 of the outer air guide plate 2 at the bottom, which increases the air guiding distance compared with the conventional microporous air guide plate; in the conventional heating mode, the inner air guide plate 3 assists the outer air guide plate 2 to jointly compress the air, and the air compression effect is better than that of the previous microporous air guide plate; the inner air guide plate 3 and the outer air guide plate 2 cooperate to realize the windless heating mode, so as to achieve the windless heating.

[0123] The outer air guide plate 2 is an arc-shaped plate, so that in the first windless cooling mode and the second windless cooling mode, the first air dissipation hole 21 has a larger cooling area, a faster cooling speed and a better cooling effect.

[0124] The central angle (radian) A of the outer air guide plate 2 is relatively large, and can basically cover the entire air outlet 11 in the second windless state; the central angle (radian) B of the inner air guide plate 3 is relatively small, and mainly plays a role in coordinating the wind guidance.

[0125] Since the inner air guide plate 3 adopts a hole-free (air dispersion hole) design or adopts the second air dispersion holes 31 formed by fine holes, the cooling effect in the conventional cooling mode or the compressed air effect in the conventional heating mode is better than that of the conventional microporous air guide plate.
