[0002] With the continuous development of air conditioning technology, users have increasingly higher requirements for the comprehensive performance of air conditioners, especially the air supply experience of indoor units, which has always been a major concern for users. Specifically, most existing air conditioners are equipped with only a single-layer air deflector. This structural arrangement not only cannot avoid the problem of direct blowing, especially when the air conditioner is operating in cooling mode, the cold air blown directly from the indoor unit hitting the human body can easily cause user discomfort; it also limits the direction and range of air output, making it unable to meet the high air output requirements of some users.

[0003] Furthermore, in order to effectively alleviate the problem of direct blowing, some existing air conditioners have also made some improvements to the structure of their air guide plates. However, the effects of these structural improvements are not obvious. Therefore, most of the existing air conditioners still adjust the air supply logic to avoid the discomfort caused by direct blowing. However, this method of adjusting the air supply logic can easily affect the heat exchange speed of the air conditioner, thereby causing the problem of slow changes in indoor temperature, and it is also impossible to increase the air outlet range of the air conditioner.

Specifically, the connecting plate 11 can be connected to the outer side wall of the cabinet of the indoor unit, and the plurality of air guide plates 12 are connected with the connecting plate 11, so that the air guide plate 12 can move relative to the main body of the indoor unit through the connecting plate 11, thereby changing the air guide state of the air guide device, and the air guide device can realize the effect of layered air guide through the plurality of air guide plates 12, thereby effectively ensuring the softness of the air outlet. It should be noted that the present application does not make any limitation on the specific shape and structure of the connecting plate 11 and the specific number of the air guide plates 12 and the specific connection mode thereof with the connecting plate 11, and the skilled person can adjust them according to the actual use requirements.

[0032] Specifically, in the preferred embodiment, the air guide device comprises four connecting plates 11 and three air guide plates 12, the three air guide plates 12 are a first air guide plate 121 located above, a second air guide plate 122 located in the middle and a third air guide plate 123 located below, two connecting plates 11 are arranged at the left and right ends of the first air guide plate 121, the second air guide plate 122 and the third air guide plate 123, and the other two connecting plates 11 are arranged at the middle of the first air guide plate 121, the second air guide plate 122 and the third air guide plate 123. Referring to the orientation in Figure 3 , the first air guide plate 121, the second air guide plate 122 and the third air guide plate 123 are connected with the connecting plate 11 in a top-down manner, that is, when the air guide device is in the air guide position, the three air guide plates 12 are distributed in a top-down manner, so as to effectively realize the effect of layered air supply. It should be noted that although the air guide device described in the preferred embodiment comprises four connecting plates 11 and three air guide plates 12, this is not limiting, and the skilled person can set it according to the actual use requirements, for example, the number of connecting plates 11 can also be one, and the number of air guide plates 12 can also be two or more. Such changes in the specific number do not deviate from the basic principles of the present application and should be within the protection scope of the present application.

[0033] Continuing to refer to Figure 4 and Figure 5 , wherein, Figure 4 is a side view of the air guide device of the present application; Figure 5 is a side sectional view of the air guide device of the present application. As Figures 1 to 5As shown, the outer side of the two connecting plates 11 at both ends is provided with a rotating shaft 14, and the position close to the air outlet of the air outlet channel of the indoor unit is provided with two mounting holes (not shown in the figure), and the air guiding device is rotatably connected to the indoor unit through the rotating shaft 14 arranged on the connecting plate 11, so that the air guiding device can rotate between the storage position and each air guiding position. Preferably, a driving motor is arranged in the mounting hole of the indoor unit, and the driving shaft of the driving motor is connected with one of the rotating shafts 14, so as to realize the effect of automatic driving. Of course, the specific shape of the connecting plate 11 and the rotating shaft 14 is not limited in the present application, and the skilled person can set it according to the actual use requirement. In addition, the two connecting plates 11 in the middle form an avoiding groove 15, and part of the air guiding plate 12 is disconnected here. The air guiding device can ensure the smoothness of the rotating process through the avoiding groove 15, thereby effectively ensuring the accuracy of air guiding. Of course, this structure is not restrictive, and the skilled person can set it according to the actual use requirement.

[0034] Further, a plurality of supporting ribs 13 are arranged between the first air guiding plate 121, the second air guiding plate 122 and the third air guiding plate 123, so as to effectively prevent the problem that the air guiding plate 12 is easily deformed due to heat. Preferably, the plane where the supporting rib 13 is located is parallel to the plane where the connecting plate 11 at both ends is located, so as to improve the connection strength without affecting the air guiding effect of the air guiding device. It should be noted that the present application does not limit the specific structure, the number and the arrangement position of the supporting rib 13, as long as the supporting rib 13 can be connected between the first air guiding plate 121, the second air guiding plate 122 and the third air guiding plate 123 to improve the connection strength.

[0035] Continue to refer to Figure 5 As Figure 5As shown, the air guiding surfaces of the first air deflector 121, the second air deflector 122 and the third air deflector 123 are all arc-shaped, that is, the upper and lower surfaces of the first air deflector 121, the second air deflector 122 and the third air deflector 123 are all arc-shaped, so as to effectively reduce the wind resistance and improve the air outlet noise problem. It should be noted that the skilled person can set the specific arc of the first air deflector 121, the second air deflector 122 and the third air deflector 123 according to the actual use requirement. Further preferably, the widths of the first air deflector 121, the second air deflector 122 and the third air deflector 123 increase in turn along the top-down direction, that is, the width of the first air deflector 121 is the smallest, the width of the second air deflector 122 is the second, and the width of the third air deflector 123 is the largest, thereby effectively improving the fluency of the air guiding device during rotation, and further effectively ensuring the posture control ability of the air conditioner to the air guiding device, so as to effectively ensure the air supply effect. It should be noted that the width referred to here is the size of the air deflector 12 in the air guiding direction. In addition, the first air deflector 121, the second air deflector 122 and the third air deflector 123 are fan-shaped distributed, and the spacing between the first air deflector 121 and the second air deflector 122 is equal to the spacing between the second air deflector 122 and the third air deflector 123, so as to effectively expand the air supply range, and also effectively reduce the loss of air volume.

[0036] Continuing to refer to Figure 1 and Figure 3 Further, a plurality of recessed structures 124 are arranged on the outer side surfaces of the two outermost air deflectors 12, as shown in Figure 1 and Figure 3 In the preferred embodiment, the upper surface of the first air deflector 121 and the lower surface of the third air deflector 123 are both provided with a plurality of recessed structures 124, and the lower surface of the first air deflector 121, the upper and lower surfaces of the second air deflector 122 and the upper surface of the third air deflector 123 are all flat surfaces, so as to effectively ensure the air guiding effect. When the air conditioner operates in the cooling mode, the air blown out by the indoor unit is cold air, and the temperature of the external air is relatively high, so it is easy to produce condensation phenomenon on the upper surface of the first air deflector 121 and the lower surface of the third air deflector 123, thereby causing the problem of water dripping from the indoor unit; based on this, the present application effectively avoids the generation of condensation phenomenon by arranging a plurality of recessed structures 124 on the outer side surfaces of the two outermost air deflectors 12, thereby effectively improving the user experience. It should be noted that the present application does not make any limitation on the specific shape, number and arrangement of the recessed structures 124, and the skilled person can adjust them according to the actual use requirement, which is not limited.

[0037] As a preferred arrangement of the recessed structures 124, a plurality of the recessed structures 124 are arranged in an array on the upper surface of the first air deflector 121 and the lower surface of the third air deflector 123, so as to effectively ensure the anti-condensation effect of the entire air deflector. Further, the projection shape of the recessed structures 124 is arranged as a circle, i.e., the surface of the recessed structures 124 is a part of a spherical surface, so as to achieve a better anti-condensation effect. Preferably, the edges of the recessed structures 124 can also be chamfered, so as to maximize the anti-condensation effect of the air deflector. Of course, the skilled person can set the size of the recessed structures 124 according to the specific size of the air deflector 12 and the specific use requirements of the user. It should be noted that the above arrangement is only a preferred arrangement, but not a limiting arrangement, and the skilled person can adjust it according to the actual use requirements.

[0038] Further, at least one positioning guide column 125 is arranged on the end surface of the air deflector 12, with reference to the orientation in Figure 3 , the end surface in the present application refers to the front surface and the rear surface of the air deflector 12. The axis direction of the positioning guide column 125 is consistent with the tangent direction of the air deflector 12 at that place, so as to effectively position the air outlet direction of the indoor unit, and further to more effectively control the air outlet direction. It should be noted that the present application does not make any limitation on the specific shape, arrangement number and arrangement position of the positioning guide column 125, and the skilled person can set it according to the actual use requirements. Preferably, the positioning guide column 125 is arranged as a prismatic column, and one diagonal of the rhombus is parallel to the tangent surface of the air deflector 12 at that place, and the other diagonal is perpendicular to the tangent surface of the air deflector 12 at that place, so as to better position and guide. Of course, this shape arrangement is only preferred, but not limiting, and the skilled person can set it according to the actual use requirements; for example, the positioning guide column 125 can also be a hexagonal column, etc.

[0039] Continuing to refer to Figure 2 , as a preferred arrangement, the number of positioning guide columns 125 is multiple, so as to better position, and the positioning guide columns 125 of the first air deflector 121, the second air deflector 122 and the third air deflector 123 are arranged one by one in the same end surface direction. As Figure 2As shown, in the plane in which the front end faces of the first, second and third air deflectors 121, 122 and 123 are located, or in the plane in which the rear end faces of the first, second and third air deflectors 121, 122 and 123 are located, the positioning guide posts 125 provided on the first air deflector 121, the positioning guide posts 125 provided on the second air deflector 122 and the positioning guide posts 125 provided on the third air deflector 123 are arranged in one-to-one correspondence, that is, the positioning guide posts 125 on the three air deflectors 12 are located on the same straight line, in other words, arranged in sequence from top to bottom in the vertical direction, so as to effectively ensure the consistency of the guiding result and further improve the accuracy of positioning and guiding.

[0040] Further, the positioning guide posts 125 on the front end face and the positioning guide posts 125 on the rear end face are arranged in a staggered manner, that is, the positioning guide posts 125 on the front end face and the positioning guide posts 125 on the rear end face are not arranged on the same straight line along the air deflection direction, but are arranged in a staggered manner, so that the positioning guide posts 125 on the front end face and the positioning guide posts 125 on the rear end face can be positioned from different directions, thereby maximizing the accuracy of the positioning result.

[0041] In addition, the indoor unit (not shown in the figure) of the present application is also provided with an outer air deflector (not shown in the figure), the air deflector can be accommodated in the air outlet channel of the indoor unit, the outer air deflector can shield the air outlet of the air outlet channel, and the outer air deflector and the air deflector are arranged together so that the air blown out through the air outlet channel of the indoor unit passes through the guiding of the air deflector and the outer air deflector in sequence when the outer air deflector and the air deflector are both located in the air deflection position. It should be noted that the present application does not specifically set the air deflection position, and the skilled person can set one or more air deflection positions according to the actual use requirements, so that the indoor unit can realize various air supply modes under the cooperation of the outer air deflector and the air deflector, so as to effectively improve the diversity of the air supply mode on the basis of ensuring the softness and range of the air outlet, thereby achieving better air supply effect.

[0042] So far, the technical solutions of the present application have been described in combination with the preferred embodiments shown in the drawings, but those skilled in the art can easily understand that the protection scope of the present application is obviously not limited to these specific embodiments. Those skilled in the art can make equivalent changes or replacements to the related technical features without departing from the principles of the present application, and the technical solutions after these changes or replacements will all fall within the protection scope of the present application.
