[0041] The embodiment of the present application provides an air guide structure to eliminate the air outlet blind area on the side of the air guide plate facing away from the air outlet, thereby improving the uneven temperature phenomenon of the existing air guide plate and further improving the "condensation" phenomenon of the existing air guide plate. The following will be described with reference to the accompanying drawings.

[0042] In the embodiments of this application, Figures 1 to 7 As shown, the air guide structure 1 includes a first air guide plate 11 and a second air guide plate 12. The first air guide plate 11 defines a ventilation cavity 111, and the second air guide plate 12 is rotatable to open or close the ventilation cavity 111. The first air guide plate 11 is used to rotatably open or close the air outlet 101 of the air conditioner indoor unit 10. The first air guide plate 11 includes an air guide surface 112 and a back side surface 113 disposed opposite each other. When the first air guide plate 11 covers the air outlet 101, the air guide surface 112 faces the interior of the air conditioner indoor unit 10. The second air guide plate 12 includes a first air guide end 121. When the first air guide plate 11 is rotated to a target opening angle, the end of the air guide surface 112 facing away from the interior of the air conditioner indoor unit 10 is referred to as the first end. The second air guide plate 12 is rotatable so that the first air guide end 121 extends from the back side surface 113 away from the air guide surface 112, with the first air guide end 121 facing the first end, so that the second air guide plate 12 is tilted relative to the first air guide plate 11.

[0043] It should be noted that the first air guide plate 11 can be rotated to the target opening angle. When the air is discharged, there is an inclination angle between the first air guide plate 11 and the horizontal plane (parallel to the ground). There is an air outlet blind spot on the side of the back side 113 away from the air guide surface 112. The air outlet blind spot refers to the area that the wind flow cannot reach. If the second air guide plate 12 is not provided, the air outlet blind spot will cause a large temperature difference between the air guide surface 112 and the back side 113 of the first air guide plate 11, thereby causing "condensation" phenomenon. In an embodiment of the present application, when the first air guide plate 11 is rotated to the target opening angle, the second air guide plate 12 can be rotated so that the first air guide end 121 extends out of the side of the back side 113 away from the air guide surface 112, and the first air guide end 121 is directed toward the air outlet blind area of the first air guide plate 11, so that a part of the air outlet air flow can be discharged along the air guide surface 112, and the other part of the air outlet air flow can flow along the surface of the second air guide plate 12 to the first air guide end 121 to guide the air outlet blind area of the first air guide plate 11, so that different areas on the first air guide plate 11 have air outlet air flow flowing through, thereby making the temperature difference between different areas on the first air guide plate 11 smaller, avoiding condensation on the first air guide plate 11 due to uneven hot and cold in different areas.

[0044] The target opening angle may be: in order to achieve the air supply effect required by the user, the first air guide plate needs to be rotated from the covering position to open the angle; at this angle, the air blown out through the air outlet can make the user feel comfortable, and the angle is variable. Specifically, the target opening angle of the air-conditioning indoor unit 10 in the cooling state may be different from the target opening angle of the air-conditioning indoor unit 10 in the heating state. For example, the target opening angle is the angle between the first air guide plate 11 and the horizontal plane (parallel to the ground). Based on the fact that the density of cold air is greater than that of hot air, the target opening angle of the air-conditioning indoor unit 10 in the heating state is greater than the target opening angle of the air-conditioning indoor unit 10 in the cooling state, so as to force the hot air to blow downward.

[0045] In the first air guide plate 11, the air guide surface 112 and the back surface 113 are, for example, arranged opposite each other along the thickness direction. It is understood that the air guide structure 1 also includes a driving component for driving the first air guide plate 11 to rotate along a rotation axis parallel to its own length. The driving component can be, for example, a second motor. Furthermore, the location of the ventilation cavity 111 on the first air guide plate 11 is not specifically limited. The ventilation cavity 111 is, for example, located in the middle of the first air guide plate 11. There can be one or more ventilation cavities 111, but in this example, there is only one ventilation cavity 111.

[0046] The second air guide plate 12 may be one or more, and specifically, the number of the second air guide plates 12 is the same as the number of the ventilation cavities 111, so that each second air guide plate 12 can rotatably open or close a ventilation cavity 111. To facilitate air guiding, the cross section of the first air guide end 121 is crescent-shaped.

[0047] In some embodiments of the present application, when the first air guide plate 11 is rotated to the target opening angle, the second air guide plate 12 is tilted relative to the first air guide plate 11, and the angle formed between the first air guide plate 11 and the second air guide plate 12 is 30° to 50°, for example, it can be 30°, 35°, 40°, 45°, 50° or a value between any two of the aforementioned values, which can completely eliminate the air outlet blind spot of the first air guide plate 11.

[0048] In some embodiments of the present application, the second air guide plate 12 can rotate along a rotation axis, and the rotation axis is parallel to the length direction of the second air guide plate 12 or the rotation axis is parallel to the width direction of the second air guide plate 12; the second air guide plate 12 includes a first air guide end 121 and a second air guide end 122 that are relatively arranged, and the rotation axis is located at the second air guide end 122 or the rotation axis is located between the first air guide end 121 and the second air guide end 122.

[0049] Furthermore, the rotation axis is located between the first air guide end 121 and the second air guide end 122. When the first air guide plate 11 is rotated to the target opening angle, the second air guide plate 12 can be rotated to make the first air guide end 121 extend to the side of the back side 113 away from the air guide surface 112, and make the second air guide end 122 extend to the side of the air guide surface 112 away from the back side 113.

[0050] In some embodiments of the present application, the air guide structure 1 further includes a rotating shaft 13, which connects the first air guide plate 11 and the second air guide plate 12; the rotating shaft 13 is located at the second air guide end 122, or the rotating shaft 13 is located between the first air guide end 121 and the second air guide end 122.

[0051] When the rotating shaft 13 is located at the second air-guiding end 122, the second air-guiding end 122 can rotate around the first air-guiding end 121. The first air-guiding end 121 and the second air-guiding end 122 can be arranged opposite each other along the length of the second air-guiding plate 12, or along the width of the second air-guiding plate 12. The first air-guiding end 121 can be connected to any wall of the ventilation cavity 111.

[0052] In some embodiments of this application, see Figure 1 and Figure 2 The cavity wall of the ventilation cavity 111 is provided with a rotating hole 114, one end of the rotating shaft 13 is connected to the second air guide plate 12, and the other end of the rotating shaft 13 is adapted to be arranged in the rotating hole 114, so that the rotating shaft 13 is driven to rotate by the rotation of the first air guide plate 11, so that the second air guide plate 12 rotates around the rotating shaft 13, and the second air guide plate 12 rotates relative to the first air guide plate 11.

[0053] Furthermore, a first limiting portion 1141 is provided on the sidewall of the rotation hole 114, and a second limiting portion 131 is provided on the peripheral wall of the rotation shaft 13. One of the first limiting portion 1141 and the second limiting portion 131 is a limiting protrusion, and the other is a limiting groove. The limiting protrusion is embedded in the limiting groove, and the limiting protrusion can rotate between the opposite sidewalls of the limiting groove. When the first air deflector 11 rotates to the target opening angle, a specific angle is formed between the first air deflector 11 and the second air deflector 12, thereby completely eliminating the air outlet blind spot of the first air deflector 11. The number of limiting grooves can be one or more, and the number of limiting protrusions can be one or more. The number of limiting grooves is the same as the number of limiting protrusions, so that one limiting protrusion is correspondingly embedded in one limiting groove.

[0054] As an example, continue to see Figure 2 The first limiting portion 1141 is a limiting groove, and the second limiting portion 131 is a limiting protrusion. There are multiple first limiting portions 1141, which are sequentially spaced apart along the circumferential direction of the side wall of the rotating hole 114. Correspondingly, there are multiple second limiting portions 131, which are sequentially spaced apart along the circumferential direction of the peripheral wall of the rotating shaft 13.

[0055] It should be noted that if Figure 3 As shown, Figure 3 The middle arrow represents the wind direction. When the first air guide plate 11 rotates to the target opening angle, the first air guide plate 11 stops rotating. Based on the thrust of the wind, for example, the second air guide end 122 is closest to the air outlet and receives the greatest thrust, thereby driving the second air guide plate 12 to continue rotating in the original direction (clockwise or counterclockwise) until it is limited, so that the first air guide plate 11 and the second air guide plate 12 are tilted, and based on the thrust of the wind, the angle between the first air guide plate 11 and the second air guide plate 12 can be maintained within a specific range, so that part of the air flow can flow along the surface of the second air guide plate 12 to the first air guide end 121 to guide the air outlet blind area of the first air guide plate 11, so that different areas on the first air guide plate 11 have air flow.

[0056] In some embodiments of this application, see Figures 1 to 5The second air guide plate 12 is provided with a receiving cavity 123, and a counterweight 124 is provided in the receiving cavity 123. When the first air guide plate 11 rotates, the counterweight 124 can move in the receiving cavity 123 to change the center of gravity of the second air guide plate 12, so that the second air guide plate 12 rotates around the rotation axis. When the first air guide plate 11 rotates to the target opening angle, the first air guide plate 11 stops rotating. Based on the change of the center of gravity of the second air guide plate 12 by the counterweight 124, the second air guide plate 12 continues to rotate in the original direction (clockwise or counterclockwise) until it is limited, thereby forming a specific angle between the first air guide plate 11 and the second air guide plate 12, and maintaining the angle unchanged in the cooling state or the heating state, thereby completely eliminating the air outlet blind spot of the first air guide plate 11.

[0057] As an example, the counterweight 124 is a liquid medium that can move within the receiving chamber 123 to change the center of gravity of the second air deflector 12, thereby causing the second air deflector 12 to rotate about the rotation axis. When the first air deflector 11 rotates to the target opening angle, the center of gravity of the second air deflector 12 changes based on the skewed distribution of the liquid medium within the receiving chamber 123.

[0058] In other embodiments of the present application, Figure 6 As shown, the air guide structure 1 also includes a first motor 14, which is driven and connected to the second air guide plate 12 to drive the second air guide plate 12 to rotate and open or close the ventilation cavity 111. As an example, the first motor 14 is connected to the rotating shaft 13 to drive the second air guide plate 12 to rotate and open or close the ventilation cavity 111. It should be noted that when the first air guide plate 11 rotates to the target opening angle, the first air guide plate 11 stops rotating, and the first motor 14 can drive the second air guide plate 12 to continue rotating in the original direction (clockwise or counterclockwise) until it is limited, thereby forming a specific angle between the first air guide plate 11 and the second air guide plate 12, and maintaining the angle unchanged in the cooling state or the heating state, thereby completely eliminating the air outlet blind spot of the first air guide plate 11.

[0059] In other embodiments of the present application, Figure 7As shown, the air guide structure 1 further includes a magnet 15 and an electromagnetic module 16. The magnet 15 is disposed on one of the first air guide plate 11 and the second air guide plate 12, and the electromagnetic module 16 is disposed on the other of the first air guide plate 11 and the second air guide plate 12. When the first air guide plate 11 rotates to a target opening angle, the electromagnetic module 16 is electrically attracted to or repelled from the magnet 15, thereby driving the second air guide plate 12 to rotate and open or close the ventilation cavity 111. It should be noted that when the first air guide plate 11 rotates to a target opening angle, the first air guide plate 11 stops rotating. Based on the attractive force or repulsive force between the electromagnetic module 16 and the magnet 15, the second air guide plate 12 can be driven to continue rotating in the original direction (clockwise or counterclockwise) until it is limited, thereby forming a specific angle between the first air guide plate 11 and the second air guide plate 12, and maintaining the angle unchanged in the cooling state or the heating state, thereby completely eliminating the air outlet blind spot of the first air guide plate 11.

[0060] The embodiment of the present application also provides an air conditioner indoor unit, such as Figure 8 As shown, the air-conditioning indoor unit 10 includes an air guide structure 1 and a casing 2. The casing 2 is provided with an air outlet 101. The air guide structure 1 is arranged at the air outlet 101. The specific structure of the air guide structure 1 refers to the above embodiment. Since the air-conditioning indoor unit 10 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0061] It is understandable that the air conditioner indoor unit 10 also includes some conventional components, such as: Figure 8 The air conditioner indoor unit 10 further includes an evaporator assembly 3 and a fan 4, and the evaporator assembly 3 and the fan 4 are respectively arranged in the casing 2.

[0062] The air guiding principle of the air conditioner indoor unit 10 is described by taking the cooling state as an example. The air guiding principle of the air conditioner indoor unit 10 in the heating state is similar to that in the cooling state. Figure 8 , Figure 8 The middle arrow represents the wind direction. When the first air guide plate 11 rotates to the target opening angle, the first air guide plate 11 stops rotating to introduce the wind blown out from the air outlet 101 to the wind guide surface 112 into the room at a suitable angle. The second air guide plate 12 continues to rotate in the original direction (clockwise or counterclockwise) until it is limited, so that the wind blown out from the air outlet 101 to the second air guide plate 12 is introduced into the room from the back side 113 of the first air guide plate 11 away from the wind guide surface 112, thereby eliminating the wind guide blind spot of the first air guide plate 11.

[0063] In order to improve the user experience, in some embodiments of the present application, one or more of the housing 2, the first air guide plate 11 and the second air guide plate 12 are provided with a light-changing powder coating, so that the appearance of the entire machine is white when there is sunlight during the day, and the appearance of the entire machine is black when there is no sunlight at night.

[0064] In the above embodiments, the description of each embodiment has its own focus. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0065] The above is a detailed introduction to an air guide structure and an air-conditioning indoor unit including an air guide structure provided in an embodiment of the present application. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea; at the same time, for technical personnel in this field, based on the ideas of the present application, there will be changes in the specific implementation methods and application scope.
