In other instances, well-known structures and processes are not described in detail to avoid obscuring the description of this application with unnecessary detail. Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0034] This application provides an air guide structure to solve the problem of not having an air guide plate that can be adapted to different models. The following description will be provided in conjunction with the accompanying drawings.

[0035] In the embodiments of this application, such as Figure 1 As shown, the air guiding structure includes:

[0036] First air guide plate 1;

[0037] Second air guide plate 2; and,

[0038] The third air guide plate 3 is detachably connected between the first air guide plate 1 and the second air guide plate 2;

[0039] Along the first direction, the first air guide plate 1, the third air guide plate 3 and the second air guide plate 2 are arranged in sequence. One end of the first air guide plate 1 and one end of the second air guide plate 2 are used to rotatably connect to the main body of the indoor unit of the air conditioner.

[0040] It should be noted that detachable connections include snap-fit ​​connections, clip-on connections, bolt connections, pin connections, and other connection methods. The first air guide plate 1 is rotatably connected to the main body of the indoor unit along one end in the first direction, and the second air guide plate 2 is rotatably connected to the main body of the indoor unit along one end in the first direction. Generally speaking, along the length of the indoor unit, both ends of the air guide structure are rotatably connected to the main body of the indoor unit; therefore, the first direction is the length direction of the indoor unit.

[0041] It is understandable that by setting a detachably connected third air guide plate 3 between the first air guide plate 1 and the second air guide plate 2, the length of the air guide structure in the length direction of the air conditioner indoor unit is extended. Third air guide plates 3 of different sizes can be produced for selective installation on different models of air conditioner indoor units, saving the mold opening cost of the entire air guide block, and adapting to the air outlet size of various models.

[0042] In some embodiments, such as Figure 2 and Figure 3 As shown, the first air guide plate 1 and the second air guide plate 2 are detachably connected.

[0043] It should be noted that detachable connections include snap-fit ​​connections, bolt connections, pin connections, and other connection methods.

[0044] It is understandable that when the current model's requirements can be met without the need for the third air guide plate 3, the first air guide plate 1 and the second air guide plate 2 can be directly connected. For example, the first air guide plate 1 is provided with a first slot 12, and the second air guide plate 2 is provided with a second insert 22, with the first slot 12 used for the insertion of the second insert 22.

[0045] In some embodiments, such as Figure 1 , Figure 2 as well as Figure 3 As shown, the first air guide plate 1 is provided with a first slide rod 13, and the second air guide plate 2 is provided with a second slide groove 231. The first slide rod 13 is slidably connected to the second slide groove 231 to adjust the distance between the first air guide plate 1 and the third air guide plate 3 along the first direction.

[0046] Understandably, by sliding and adjusting the insertion depth of the first slide rod 13 within the second slide groove 231, the distance between the first air guide plate 1 and the second air guide plate 2 can be changed to accommodate third air guide plates 3 of different sizes. Furthermore, when it is not necessary to extend the length of the air guide structure via the third air guide plate 3, the cooperation between the first slide rod 13 and the second slide groove 231 can connect the first air guide plate 1 and the second air guide plate 2 into one unit, allowing the air guide structure to better guide airflow.

[0047] In some embodiments, such as Figure 1 As shown, along the first direction, one end of the first air guide plate 1 is provided with a first slot 12, one end of the second air guide plate 2 is provided with a second insert 22, and both ends of the third air guide plate 3 are respectively provided with a third insert 32 and a third slot 33.

[0048] The first slot 12 is used for the insertion of the third plug 32, and the second plug 22 is used for the insertion of the third slot 33; or, the first slot 12 is used for the insertion of the second plug 22.

[0049] It should be noted that the first slot 12 is located on the side of the first air guide plate 1 facing the third air guide plate 3, and the first slot 12 is located on the side of the second air guide plate 2 facing the third air guide plate 3.

[0050] Understandably, when the third air guide plate 3 is needed, the first air guide plate 1 is slid first, adjusting the length of the first sliding rod 13 within the second sliding groove 231 to a suitable size. Then, the third insert 32 is inserted into the first slot 12, and the second insert 22 is inserted into the third slot 33, completing the assembly of the third air guide plate 3. When the third air guide plate 3 is not needed, the second insert 22 is inserted into the first slot 12. Based on the cooperation between the first sliding rod 13 and the second sliding groove 231, the connection reliability between the first air guide plate 1 and the second air guide plate 2 is further improved.

[0051] In some embodiments, such as Figure 2 and Figure 3 As shown, the first slide bar 13 is located on the windward side of the first air guide plate 1, and the second slide groove 231 is located on the windward side of the second air guide plate 2.

[0052] It should be noted that the windward side refers to the side of the first air guide plate 1 and the second air guide plate 2 facing the cross-flow fan of the indoor air conditioning unit. The side opposite to the windward side is the leeward side, which is the exterior surface.

[0053] It is understandable that the first slide rod 13 and the second slide groove 231 being located on the windward side can ensure the aesthetic appearance of the air guide structure. For example, the first slide rod 13 is protrudingly disposed on the windward side of the first air guide plate 1; the windward side of the second air guide plate 2 is provided with a second slide rail 23, the second slide rail 23 is provided with a second slide groove 231, and the groove opening of the second slide rail 231 is located on the side of the second slide rail 23 facing the third air guide plate 3.

[0054] In some embodiments, multiple third air guide plates 3 are provided along the first direction, and adjacent third air guide plates 3 are detachably connected. The outermost third air guide plate 3 is detachably connected to the first air guide plate 1 and the second air guide plate 2.

[0055] It should be noted that detachable connections include connection methods such as snap-fit, clip-on, bolt connection, and pin connection. The detachable connection methods between adjacent third air guide plates 3, between the first air guide plate 1 and the outermost third air guide plate 3, and between the second air guide plate 2 and the outermost third air guide plate 3 can be the same or different. The outermost third air guide plate 3 refers to the third air guide plates 3 located at both ends among all the third air guide plates 3 arranged along the first direction; these two third air guide plates 3 are respectively connected to the first air guide plate 1 and the second air guide plate 2.

[0056] Understandably, when one third air guide plate 3 cannot meet the requirements, multiple third air guide plates 3 can be connected together.

[0057] For example, such as Figure 4 As shown, the third air guide plate 3 has a third insert 32 and a third slot 33 at both ends, respectively. The third insert 32 of one of the third air guide plates 3 is inserted into the third slot 33 of the adjacent third air guide plate 3.

[0058] In some embodiments, such as Figure 2 As shown, the windward side of the first air guide plate 1 is provided with multiple first grooves 11, such as... Figure 3 As shown, the windward side of the second air guide plate 2 is provided with multiple second grooves 21, such as... Figure 4 As shown, the windward side of the third air guide plate 3 is provided with multiple third grooves 31; as Figure 1 As shown, along the second direction, a plurality of first grooves 11 are arranged in sequence, a plurality of second grooves 21 are arranged in sequence, and a plurality of third grooves 31 are arranged in sequence, with the second direction being perpendicular to the first direction.

[0059] It should be noted that, generally speaking, along the length of the indoor unit of the air conditioner, the two ends of the air guide structure are rotatably connected to the main body of the indoor unit. So the first direction is the length of the indoor unit of the air conditioner, which is also the length direction of the air guide structure, and the second direction is the width direction of the air guide structure.

[0060] Understandably, the multiple first grooves 11, multiple second grooves 21, and the third groove 31 can disrupt the airflow on the windward side surface of the air guide structure, reduce the convection intensity between the airflow blown out by the indoor unit of the air conditioner and the outside air, and reduce condensation.

[0061] In some embodiments, such as Figure 2 , Figure 3 as well as Figure 4 As shown, the depths of the multiple first grooves 11 are different, the depths of the multiple second grooves 21 are different, and the depths of the multiple third grooves 31 are different.

[0062] Understandably, based on the positional differences of the first air guide plate 1 relative to the air outlet of the indoor unit of the air conditioner, multiple first grooves 11 of different depths can be set at different positions on the first air guide plate 1 to achieve a better anti-condensation effect.

[0063] In some embodiments, such as Figure 1 , Figure 2 as well as Figure 3 As shown, at least a portion of the first groove 11 increases in the direction from the third air guide plate 3 to the first air guide plate 1; at least a portion of the second groove 21 increases in the direction from the third air guide plate 3 to the second air guide plate 2.

[0064] Understandably, because the first air guide plate 1 is closer to the side wall of the air outlet of the indoor unit of the air conditioner on the side facing away from the third air guide plate 3, cold air tends to condense there. By increasing the size of the first groove 11 near the confluence point, the airflow blown out by the indoor unit of the air conditioner is more significantly turbulent, reducing airflow condensation and thus reducing condensation at both ends of the air guide structure along its length. The second groove 21 on the second air guide plate 2 follows the same design and effect as the first groove 11.

[0065] In some embodiments, such as Figure 2 and Figure 3 As shown, the portion of the first groove 11 located near the pivot of the first air guide plate 1 is larger than the other first grooves 11, and the portion of the second groove 21 located near the pivot of the second air guide plate 2 is larger than the other second grooves 21.

[0066] It is understandable that the portion of the first groove 11 located near the pivot of the first air guide plate 1 should be significantly larger than the other first grooves 11, and the portion of the second groove 21 located near the pivot of the second air guide plate 2 should be significantly larger than the other second grooves 21. In this way, the aforementioned first groove 11 and second groove 21 near the pivot not only have a stronger turbulence effect, but also improve the structural strength of the first air guide plate 1 and the second air guide plate 2.

[0067] In some embodiments, such as Figure 2 , Figure 3 as well as Figure 4 As shown, the multiple first grooves 11, multiple second grooves 21 and multiple third grooves 31 are all configured to increase in size along the air outlet direction of the indoor unit of the air conditioner.

[0068] Understandably, when the air guide structure is flipped open to the air guide state, one side of the air guide structure along the air outlet direction is closer to the air outlet of the indoor unit of the air conditioner. The airflow from inside and outside the indoor unit converges here, easily forming convection and thus producing condensation. By increasing the size of the first groove 11, the second groove 21, and the third groove 31 near the air outlet, the turbulence effect is enhanced, the convection intensity is reduced, and condensation is decreased. At the same time, it also weakens the direct current jet, providing a certain degree of gentler airflow.

[0069] For example, such as Figure 2 As shown, by protruding at least a portion of the surface of the first air guide plate 1 on the windward side to different heights and simultaneously recessing it inward to different depths, a plurality of first grooves 11 with different depths are formed. Specifically, along the air outlet direction of the indoor unit of the air conditioner, the groove opening ends of some of the first grooves 11 are higher than the groove opening ends of some of the first grooves 11, and the groove bottoms of some of the first grooves 11 and the groove opening ends of some of the first grooves 11 are located on the same plane or arc surface. Furthermore, as... Figure 3 and Figure 4 As shown, the windward sides of the second air guide plate 2 and the third air guide plate 3 also adopt a similar design to the windward side of the first air guide plate 1. Through the above arrangement, a portion of the sidewall of the first slot 12 and a portion of the sidewall of the third slot 33 form a concave-convex structure. Simultaneously, the third insert 32 is designed to conform to the shape of the first slot 12, and the second insert 22 is designed to conform to the shape of the third slot 33, improving the connection reliability between the first air guide plate 1 and the third air guide plate 3, and between the second air guide plate 2 and the third air guide plate 3. Furthermore, the second air guide plate 2 can be directly inserted into the first air guide plate 1, and multiple third air guide plates 3 can also be inserted together.

[0070] In some embodiments, such as Figure 1 As shown, the length of the first air guide plate 1 is greater than the length of the second air guide plate 2, and the windward side of the second air guide plate 2 is provided with a connecting part 24 for installation with the side wall of the air outlet of the indoor unit of the air conditioner.

[0071] The connecting part 24 is provided with a pin 241. One end of the pin 241 is connected to the connecting part 24, and the other end of the pin 241 is provided with a cross-shaped socket. The cross-shaped socket is used to cooperate with the side wall of the air outlet of the indoor unit of the air conditioner for installation.

[0072] Understandably, the cross-shaped socket allows the other end of the pin 241 to undergo elastic deformation, thereby enabling it to be installed in conjunction with the corresponding structure.

[0073] This application also provides an air conditioner indoor unit, which includes the above-mentioned air guide structure. The specific structure of the air guide structure is as described in the above embodiments. Since this air conditioner indoor unit adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0074] In some embodiments, the indoor unit of the air conditioner also includes a main body and conventional structures such as a heat exchanger, a cross-flow fan, and a motor disposed within the main body.

[0075] In the above embodiments, the descriptions of each embodiment have different focuses. Parts not described in detail in a particular embodiment can be referred to in the relevant descriptions of other embodiments. In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features.
