[0024] Exemplary embodiments of this application will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of this application are shown in the drawings, it should be understood that this application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of this application and to fully convey the scope of this application to those skilled in the art.

[0025] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also mean including the plural forms. The term “a plurality” means two or more (including two).

[0026] The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore specify the presence of the stated features, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in the specific order described or illustrated, unless the order is explicitly specified. It should also be understood that additional or alternative steps may be used.

[0027] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0028] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations.

[0029] like Figures 1 to 30 As shown, according to an embodiment of this application, an indoor air conditioning unit is proposed, including a housing 1, a receiving cavity for accommodating functional components and an air duct 16 are provided inside the housing 1, the housing 1 has an air outlet 11, the air outlet 11 is connected to the air duct 16, the air outlet 11 can be provided at the front of the housing 1 and is used to exhaust air into the room.

[0030] The housing 1 can house the internal functional components of the air conditioner. The housing 1 can also be provided with an air inlet 18, which can be located on a different wall from the air outlet 11. For example, the indoor unit of the air conditioner is a wall-mounted indoor unit, and the air inlet 18 can be provided on the top side of the housing 1. The air inlet 18 can be configured as a grid structure.

[0031] The functional components inside the housing 1 may include an indoor heat exchanger 6, an indoor fan, etc. The indoor heat exchanger 6 is connected to the cooling / heating system of the air conditioner. The indoor heat exchanger 6 is used to exchange heat with the air flowing through it. The indoor fan is used to guide the airflow from the air inlet 18 through the indoor heat exchange and then to the air outlet 11.

[0032] The indoor unit of the air conditioner also includes a first air guide 2. The first air guide 2 includes a swing arm 21 and a first air guide plate 22. One end of the swing arm 21 is rotatably connected to the housing 1, and the first air guide plate 22 is connected to the other end of the swing arm 21. The first air guide plate 22 is configured to swing around the air outlet 11 under the rotation of the swing arm 21.

[0033] The first air guide plate 22 refers to a plate-like structure with airflow guiding function. The first air guide plate 22 can be a closed solid plate (a closed solid plate refers to a plate whose surface is basically sealed, i.e., a plate without through holes on both sides). The surface of the first air guide plate 22 has an air-guiding function, meaning that airflow can flow along the surface of the first air guide plate 22 to adjust the air delivery angle of the air outlet 11. The first air guide plate 22 can adjust the air delivery angle of the air outlet 11, and when the indoor unit of the air conditioner is off, the first air guide plate 22 can act as a shielding and sealing component for the air outlet 11. The first air guide plate 22 can extend along the length of the air outlet 11 from one end to the other. The first air guide plate 22 can be a flat plate or an arc-shaped plate, etc.

[0034] Exemplarily, in some embodiments, reference is made to Figure 1 , Figures 8 to 11 , Figure 23 , Figure 24 As shown, the first air guide plate 22 is arranged in a roughly straight line along the length of the air outlet 11. The two side panels of the first air guide plate 22 (the panel refers to the large surface of the first air guide plate 22) are the first inner panel 221 and the first outer panel 222, respectively. The first inner panel 221 faces the inside of the housing 1, and the first outer panel faces the outside of the housing 1. The first inner panel 221 is the panel of the first air guide plate 22 facing the inside of the air outlet 11, and the first outer panel 222 is the exposed surface of the first air guide plate 22. The first outer panel 222 can serve as part of the exterior surface of the indoor unit of the air conditioner. When the airflow flows from the air outlet 11 to the first air guide plate 22, the airflow can flow along the first inner panel 221, which mainly serves as a guide. The first inner panel 221 can have a slightly outward convex arc-shaped structure along the width of the first air guide plate 22, and the main body of the first outer panel 222 can be roughly flat.

[0035] Optionally, the swing arm 21 can be connected to the end of the first air guide plate 22 in the left-right direction and is set perpendicular to the first air guide plate 22. The connection between the swing arm 21 and the first air guide plate 22 is set as an arc transition connection. The structure of the swing arm 21 and the first air guide plate 22 is simple and aesthetically pleasing.

[0036] Optionally, the swing arm 21 and the first air guide plate 22 can be an integral structure, for example, an injection-molded integral structure. The swing arm 21 can be rotatably connected to the housing 1 via a hinge or a pivot 124.

[0037] Optionally, the swing arm 21 can be disposed at the end of the housing 1 along its length, specifically on the side of the end wall 113 of the housing 1 facing the air outlet 11, i.e., inside the housing 1; the swing arm 21 can also be disposed on the outside of the end wall 113 of the housing 1 along its length, i.e., outside the housing 1. The rotation axis 123 of the swing arm 21 can be configured to be consistent with the length direction of the housing, and the swing arm 21 can extend in a direction perpendicular to the length direction of the housing 1, so that the swing arm 21 can drive the first air guide plate 22 to swing in the width direction of the air outlet 11.

[0038] For example, taking a wall-mounted indoor unit as an example, the rotation axis 123 of the swing arm 21 can be set in the left and right direction. The swing arm 21 can drive the first air guide plate 22 to swing in the vertical plane and drive the first air guide plate 22 to swing between the front side 111 and the bottom surface 112 of the casing 1 to adjust the position of the first air guide plate 22 relative to the air outlet 11.

[0039] According to some embodiments of this application, optionally, the swing arm 21 is connected to the outer side of the end of the housing 1 along its own length direction.

[0040] For example, the housing 1 is connected to two swing arms 21 at both ends along its length direction. The extension direction of the swing arms 21 is perpendicular to the length direction of the housing 1. The first air guide plate 22 extends from one end of the air outlet 11 along the length direction of the housing 1 to the other end. The two ends of the first air guide plate 22 are respectively connected to the swing arms 21 at the corresponding ends.

[0041] For example, refer to Figure 1 , Figures 8 to 11 As shown, the housing 1 includes two end walls 113 arranged opposite each other in the left-right direction, and the air outlet 11 is located between the two end walls 113. A swing arm 21 is respectively provided on the opposite side of the two end walls 113. The first air guide plate 22 is connected to the end wall 113 of the housing 1 through the swing arm 21, and the swing arm 21 is connected to the opposite side of the two end walls 113, that is, the swing arm 21 is located on the outer sides of both ends of the housing 1, which reduces the possibility of interference between the internal components of the housing 1 and the swing arm 21, and increases the range of the first air guide plate 22 swinging around the air outlet 11 under the driving action of the swing arm 21.

[0042] like Figures 1 to 11 and combined Figures 21 to 28 As shown, the air outlet 11 can be located at the bottom front of the housing 1. Specifically, the air outlet 11 includes a first outlet 12 and a second outlet 13. The first outlet 12 faces the front side of the housing 1 (the front side can be understood as the side facing the user), and the second outlet 13 faces the bottom side of the housing 1 (the bottom side can be understood as the side facing the ground). The first outlet 12 and the second outlet 13 are connected to each other.

[0043] The first outlet 12 is a part of the air outlet 11, and the second outlet 13 is another part of the air outlet 11. The air conditioner indoor unit can be a wall-mounted indoor unit. The first outlet 12 of the housing 1 can be formed at the bottom of the front side of the housing 1 and facing downwards. The second outlet 13 of the housing 1 can be formed at the front end of the bottom surface 112 of the housing 1 and facing forwards.

[0044] The air outlet 11 is configured to include a first outlet section 12 and a second outlet section 13, which can increase the air supply area of ​​the air outlet 11 and improve the adjustment range of the air supply angle. This allows users to adjust the air supply angle of the air outlet 11 as needed, thereby improving the user experience.

[0045] For example, such as Figures 1 to 7 As shown, in some implementations, the air outlet 11 is located at the bottom front end of the housing 1, and the rotation center C1 of the swing arm 21 is located in front of the centerline C3 in the front-rear direction of the housing 1 and below the centerline C4 in the vertical direction of the housing 1. The first air guide plate 22 is configured to swing between the front side 111 and the bottom surface 112 of the housing 1 under the rotation of the swing arm 21. That is, the swing arm 21 is located at the bottom front end of the housing 1. This can improve the compactness of the component arrangement, reduce the space occupied by the swing arm 21, and the swing arm 21 can drive the first air guide plate 22 to swing in the area corresponding to the air outlet 11. Within the swing stroke of the first air guide plate 22, the distance between the first air guide plate 22 and the air outlet 11 can be small, which can improve the airflow guiding effect of the first air guide plate 22.

[0046] For ease of description, the area traversed by the first air guide plate 22 under the drive of the swing arm 21 is defined as the swing stroke of the first air guide plate 22. The swing stroke of the first air guide plate 22 can cover the entire area of ​​the air outlet 11, that is, the first air guide plate 22 can swing to the two edge positions of the air outlet 11 in its own width direction.

[0047] According to some embodiments of this application, optionally, when the indoor unit of the air conditioner is turned off, the first air guide plate 22 covers the air outlet 11.

[0048] It is understandable that the first air guide plate 22 covers the air outlet 11. This can be understood as the first air guide plate 22 covering part of the air outlet 11 when the machine is off. In other words, the first air guide plate 22 can serve as at least part of the cover of the air outlet 11.

[0049] Understandably, the first air guide plate 22, as a cover for the air outlet 11 in the off state, not only shields the air outlet 11 and reduces the possibility of dust entering, but also serves as the exterior surface of the air conditioner indoor unit, making the appearance of the air conditioner indoor unit more natural in the off state. At the same time, since the first air guide plate 22 blocks the air outlet 11, the distance between the first air guide plate 22 and the air outlet 11 can be smaller within the swing stroke of the first air guide plate 22, which can improve the airflow guiding effect of the first air guide plate 22.

[0050] For example, such as Figure 1 , Figure 2 , Figure 22 As shown, in some implementations, the first air guide plate 22 can block the first outlet 12 when the unit is off. In this embodiment, the first air guide plate 22 can be flush with the front side 111 of the casing 1 when the unit is off, so as to improve the appearance consistency and integrity of the indoor unit when the unit is off.

[0051] For example, such as Figure 5 As shown, in some other implementations, the first air guide plate 22 can also block the second outlet 13 when the unit is off. In this case, when the unit is off, the first air guide plate 22 can be flush with the bottom surface 112 of the casing 1 to improve the appearance consistency and overall integrity of the indoor unit when it is off.

[0052] like Figures 1 to 11 , Figure 14 As shown, according to some embodiments of this application, optionally, an installation groove 114 is provided on the outer side of the end of the housing 1, that is, the outer side of the end wall 113 (the first wall 1133) (that is, the side where the two end walls 113 are opposite to each other), and the swing arm 21 is disposed in the installation groove 114.

[0053] The rotation center C1 of the swing arm 21 is located in the mounting groove 114, that is, the rotation axis of the swing arm 21 passes through the mounting groove 114.

[0054] For example, such as Figures 1 to 11 , Figure 14 As shown, an installation groove 114 is provided on the outer side of the end wall 113. One end of the swing arm 21 connected to the housing 1 is located in the installation groove 114. The installation groove 114 extends backward from the front edge of the end wall 113 and upward from the bottom edge of the end wall 113.

[0055] By setting the mounting groove 114, the size of the end of the swing arm 21 protruding from the housing 1 can be reduced, thereby improving the appearance consistency and integrity of the indoor air conditioning unit, reducing the possibility that the first air guide 2 is located outside the outline of the housing 1, reducing the overall size of the indoor air conditioning unit, and reducing the possibility that the protruding swing arm 21 is easily damaged.

[0056] Optionally, such as Figures 1 to 11 , Figure 14 As shown, along the front-back direction, the mounting groove 114 extends rearward from the front side 111 of the end wall 113, and along the vertical direction, the mounting groove 114 extends upward from the bottom surface 112 of the end wall 113. The end wall 113 includes a first groove wall 1141 surrounding the upper side of the mounting groove 114 and a second groove wall 1142 surrounding the rear side of the mounting groove 114. The swing arm 21 is configured to swing between the first groove wall 1141 and the second groove wall 1142.

[0057] The rotation center C1 of the swing arm 21 is spaced apart from the first groove wall 1141, and the rotation center C1 of the swing arm 21 is spaced apart from the second groove wall 1142, so as to improve the smoothness of the swing arm 21 swinging in the mounting groove 114.

[0058] The swing stroke of the swing arm 21 can be limited by the first groove wall 1141 and the second groove wall 1142, so that the swing arm 21 swings between the first groove wall 1141 and the second groove wall 1142, thereby improving the reliability of the first air guide 2.

[0059] like Figures 1 to 11 , Figure 14 As shown, according to some embodiments of this application, optionally, the first groove wall 1141 extends in the front-back direction, and the second groove wall 1142 extends in the up-down direction.

[0060] The first groove wall 1141 and the second groove wall 1142 can be connected by an arc-shaped transition.

[0061] By limiting the swing stroke of the swing arm 21 by the first groove wall 1141 and the second groove wall 1142, the swing requirement of the first air guide plate 22 around the air outlet 11 between the front side 111 and the bottom surface 112 of the housing 1 can be met. The structure is simple and easy to process.

[0062] According to some embodiments of this application, optionally, the end wall 113 is flush with the position of the mounting groove 114 along the left-right direction, or the end wall 113 is protruding relative to the swing arm 21.

[0063] In other words, the swing arm 21 does not protrude from the front side 111. This improves the appearance consistency and overall integrity of the indoor unit, reduces the possibility that the first air guide 2 is located outside the outline of the casing 1, reduces the overall size of the indoor unit, and reduces the possibility that the swing arm 21 is easily damaged due to protrusion.

[0064] In some embodiments, the housing 1 may include a face frame 110 and a chassis 120. The face frame 110 is provided with an air outlet 11 and an air inlet 18. The two ends of the face frame 110 in the left-right direction are two end walls 113. The chassis 120 is connected to the face frame 110 and is located between the two end walls 113. The chassis 120 and the face frame 110 can cooperate to form a housing cavity for accommodating the indoor fan, the indoor heat exchanger 6, and the air duct 16.

[0065] The face frame 110 can be a one-piece molded structure, and the chassis 120 can be assembled and connected to the face frame 110 by snap-fit ​​screws.

[0066] An air supply vane 121 can be installed on the chassis 120. The air supply vane 121 can swing. The drive mechanism of the air supply vane 121 and the drive components of the indoor fan can be installed on the chassis 120 respectively.

[0067] Optionally, the swing arm 21 can be connected to the face frame 110, which can increase the swing angle of the first air guide plate 22.

[0068] like Figures 10 to 14 As shown, according to some embodiments of this application, optionally, the indoor unit of the air conditioner also includes a first drive mechanism 4, which is connected to the swing arm 21 and is used to drive the swing arm 21 to swing the first air guide plate 22. The first drive mechanism 4 can be disposed at the end of the casing 1 along the length direction.

[0069] For example, the housing 1 has two end walls 113 arranged opposite each other in the left-right direction, and the air outlet 11 of the housing 1 is located between the two end walls 113. The first drive mechanism 4 can be installed on the end walls 113, either on one end wall 113 or on both end walls 113.

[0070] For example, the two end walls 113 of the housing 1 are respectively provided with a first drive mechanism 4, and the swing arms 21 at both ends are connected to the first drive mechanism 4 at both ends in a one-to-one correspondence.

[0071] In some embodiments, such as Figures 8 to 15 , Figures 16 to 20As shown, the first drive mechanism 4 includes an assembly plate 41 and a first drive component 42. The first drive component 42 is mounted on the assembly plate 41, and the assembly plate 41 is connected to the end wall 113 at the corresponding end. The output end of the first drive component 42 is connected to the swing arm 21 at the corresponding end. The first drive component 42 is configured to drive the swing arm 21 to drive the first air guide plate 22 to swing around the air outlet 11.

[0072] The first drive mechanism 4 is connected to the end wall 113 of the housing 1 via the assembly plate 41, which facilitates the connection between the swing arm 21 and the first drive component 42. During the assembly process, the first drive component 42 can be pre-assembled onto the assembly plate 41, and then the assembly plate 41 with the first drive component 42 can be assembled onto the end wall 113 of the housing 1. This reduces the assembly difficulty of the first drive component 42 and improves the ease and efficiency of assembly.

[0073] The first drive component 42 includes a power component 421, which can be a motor, specifically a stepper motor. The power component 421 can be fixed to the mounting plate 41 by fasteners such as screws.

[0074] The main body of the first drive mechanism 4 can be disposed inside or outside the end wall 113. The assembly plate 41 can be disposed inside or outside the end wall 113.

[0075] like Figures 8 to 13 , Figures 15 to 20 As shown, optionally, in some implementations, an accommodating space 1131 is provided in the end wall 113, and the first driving mechanism 4 is disposed in the accommodating space 1131.

[0076] In some implementations, an accommodating space 1131 is provided inside the end wall 113, the first driving mechanism 4 is disposed in the accommodating space 1131, an assembly hole 1136 is provided on the end wall 113, the swing arm 21 is disposed on the outside of the end wall 113, and the output end of the first driving component 42 is connected to the swing arm 21 through the assembly hole 1136.

[0077] The accommodating space 1131 can be a hollow space inside the end wall 113. The assembly hole 1136 on the end wall 113 can connect the accommodating space 1131 and the external space. The first driving component 42 and the swing arm 21 can be connected by a connector 422 passing through the assembly hole 1136.

[0078] By providing a receiving space 1131 within the end wall 113 and assembling the first drive mechanism 4 within the receiving space 1131, the possibility of exposed and easily damaged power components is reduced. At the same time, the appearance consistency and integrity of the air conditioner indoor unit can be well maintained.

[0079] Optionally, in some embodiments, the housing 1 includes a face frame 110 and a chassis 120. The face frame 110 has two end walls 113 at its two ends along the left-right direction. An assembly notch 1132 is provided on the side of the two end walls 113 facing each other. The assembly notch 1132 communicates with the accommodating space 1131. The first drive mechanism 4 is configured to assemble itself into the accommodating space 1131 through the assembly notch 1132. The chassis 120 is connected to the face frame 110, and the chassis 120 is located between the two end walls 113 and covers the assembly notch 1132.

[0080] The chassis 120 and the front frame 110 can be processed separately and then assembled and fixed. During the assembly of the indoor unit of the air conditioner, before assembling the chassis 120 and the front frame 110, the first drive mechanism 4 can be inserted into the accommodating space 1131 through the assembly notch 1132 and assembled onto the front frame 110. Then, the chassis 120 can be assembled onto the front frame 110, and the chassis 120 can be used to cover and seal the assembly notch 1132.

[0081] The first drive mechanism 4 can be easily assembled into the accommodating space 1131 through the assembly notch 1132 reserved in the face frame 110. The chassis 120 can cover and seal the assembly notch 1132, so that no additional seals are needed, which helps to improve the compactness of the components, reduce costs, and improve assembly efficiency.

[0082] like Figures 8 to 13 , Figures 15 to 20 As shown, optionally, the end wall 113 has a first wall 1133 located on one side of the accommodating space 1131. The first wall 1133 is disposed opposite to the assembly notch 1132. The assembly plate 41 is connected to the first wall 1133, and the first driving component 42 is located on the side of the assembly plate 41 away from the first wall 1133. The assembly plate 41 may be provided with a connecting hole 412, and the assembly hole 1136 may be provided in the first wall 1133. The connecting hole 412 communicates with the assembly hole 1136, and the output end of the first driving component 42 passes through the connecting hole 412 and the assembly hole 1136.

[0083] The first wall 1133 is a wall that forms the outer side of the end wall 113, and the first wall 1133 is spaced apart from the chassis 120.

[0084] The first drive mechanism 4 is mounted on the first wall 1133 via the mounting plate 41, which makes operation relatively convenient. The first drive component 42 is located on the side of the mounting plate 41 facing away from the first wall 1133, which improves the ease and reliability of assembly between the mounting plate 41 and the first wall 1133. Furthermore, during the assembly of the first drive mechanism 4 onto the first wall 1133, the first drive component 42 faces the assembly notch 1132, reducing the possibility of interference or collision between the first drive component 42 and the end wall 113, thus minimizing the risk of damage.

[0085] Optionally, such as Figures 16 to 20 As shown, the first driving mechanism 4 also includes a limiting structure 44, which is connected between the assembly plate 41 and the end wall 113. The limiting structure 44 is used to limit the swaying of the assembly plate 41 relative to the end wall 113. Specifically, the limiting structure 44 can at least limit the assembly plate 41 in one direction, thereby fixing the assembly plate 41 relative to the end wall 113 in that direction and reducing the possibility of the assembly plate 41 swaying relative to the end wall 113 in that direction.

[0086] The limiting structure 44 may include a limiting part 442 and a mating part 441. A first mating part 441 is provided on the end wall 113. A limiting part 442 is provided on one end of the assembly plate 41 corresponding to the mating part 441. The mating part 441 and the limiting part 442 are inserted into and limited to each other. Along the direction perpendicular to the insertion direction of the mating part 441 and the limiting part 442, the limiting structure 44 can restrict the shaking of the assembly plate 41.

[0087] For example, the mating part 441 and the limiting part 442 can be inserted and mated in the front-back direction, and the limiting structure 44 can limit the shaking of the assembly plate 41 in the front-back direction and the left-right direction.

[0088] One of the mating part 441 and the limiting part 442 can be a limiting groove 443, and the other can be a limiting protrusion 444. The limiting protrusion 444 can be a rib structure, and the limiting protrusion 444 and the limiting groove 443 are inserted into each other.

[0089] For example, the end wall 113 further includes a second wall 1134, which is located on the front or rear side of the accommodating space 1131. The second wall 1134 is connected to the first wall 1133. The second wall 1134 can be located at the front end of the accommodating space 1131. A limiting groove 443 is provided on the second wall 1134. A limiting protrusion 444 is provided on the front of the assembly plate 41. The limiting protrusion 444 and the limiting groove 443 are inserted and engaged to limit the shaking of the assembly plate 41 in the front-back direction and the left-right direction.

[0090] Optionally, a guide groove 445 is also provided on the limiting protrusion 444, and a guide post 446 is also provided on the limiting slot 443. The guide post 446 and the guide groove 445 can be circular in cross-section. The guide post 446 and the guide groove 445 are interlocked and can play a guiding and positioning role in the assembly process of the assembly plate 41, improving the assembly efficiency of the assembly plate 41. They can also help reduce the swaying of the assembly plate 41 in the front-back direction and the left-right direction. The end of the guide post 446 away from the limiting slot 443 can be set as a reduced diameter section to facilitate the insertion of the guide post 446 into the guide groove 445.

[0091] Optionally, such as Figures 8 to 13 , Figures 15 to 20 As shown, a positioning component 43 is provided between the end wall 113 and the assembly plate 41. The positioning component 43 is used to pre-position the installation position of the assembly plate 41.

[0092] During the process of assembling the assembly plate 41 to the end wall 113, the assembly plate 41 can be temporarily positioned by the positioning component 43, which can improve the assembly efficiency and ease of assembly of the assembly plate 41.

[0093] The positioning component 43 may include a positioning part 432 and a first adapter part 431. The adapter part 431 may be disposed on the end wall 113; the first positioning part 432 is disposed on the assembly plate 41. The positioning part 432 and the adapter part 431 cooperate to pre-position the assembly at the installation position. The adapter part 431 and the positioning part 432 may be a plug-in mating structure. For example, one of the adapter part 431 and the positioning part 432 may be a latching protrusion, and the other may be a latching groove; or, for example, one of the adapter part 431 and the positioning part 432 may be a positioning post, and the other may be a positioning hole.

[0094] Optionally, such as Figures 8 to 13 , Figures 15 to 20 As shown, in some embodiments, the positioning component 43 and the limiting structure 44 may be respectively disposed at both ends of the assembly plate 41 to cooperate with each other to pre-position the installation position of the assembly plate 41.

[0095] For example, the limiting structure 44 and the positioning component 43 are respectively disposed at both ends of the assembly plate 41 along the front-rear direction of the housing 1. The positioning part 432 and the adapter part 431 of the positioning component 43 can be inserted and engaged in the front-rear direction. The engaging part 441 and the limiting part 442 of the limiting structure 44 can also be inserted and engaged in the front-rear direction. In this way, after the assembly plate 41 is assembled towards the end wall 113 along the front-rear direction, the limiting structure 44 engages and limits one end of the assembly plate 41. At the same time, the positioning component 43 plays a temporary supporting and positioning role at the other end of the assembly plate 41. Thus, under the cooperative action of the positioning component 43 and the limiting component, the assembly plate 41 can be pre-fixed, which improves the ease of assembly.

[0096] Optionally, in some embodiments, the first drive mechanism 4 may further include a fixing component 45 for fixing the mounting plate 41 to the first wall 1133. The fixing component 45 may be a bolt assembly, screw, or other structure.

[0097] Optionally, in some embodiments, the fixing component 45 and the limiting structure 44 may be respectively disposed at both ends of the assembly plate 41, and the fixing component 45 and the limiting structure 44 cooperate to fix the assembly plate 41 to the end wall 113.

[0098] For example, the mating part 441 and the limiting part 442 of the limiting structure 44 are inserted and mated in the front-back direction, and restrict the swaying of the assembly plate 41 in the front-back direction and the left-right direction. The fixing component 45 is disposed at the other end of the assembly plate 41 opposite to the limiting structure 44, and is used to restrict the movement of the assembly part in the front-back direction. The fixing component 45 may be disposed at the same end as the positioning component 43.

[0099] Optionally, such as Figures 8 to 13 , Figures 15 to 17 As shown, in some implementations, the first wall 1133 is provided with a stepped assembly part 1135, and the assembly plate 41 is connected to the assembly part 1135.

[0100] For example, the assembly portion 1135 may be a locally thickened area of ​​the first wall 1133. The assembly portion 1135 can enhance the strength of the first wall 1133 and improve the connection strength and stability between the assembly plate 41 and the first wall 1133. Figure 16 and Figure 17 As shown, the assembly part 1135 can also be a stepped structure formed by the outer side of the first wall 1133 being recessed inward and the inner side being protruding inward. The outer recessed area of ​​the assembly part 1135 can serve as the mounting groove 114 of the swing arm 21.

[0101] Optionally, in one embodiment, the assembly part 1135 is provided with an adapter part 431 facing the rear end of the housing 1, and the assembly plate 41 is provided with a protruding plate part 47 facing the rear end of the housing 1. The protruding plate part 47 abuts against the rear end of the assembly part 1135, and a positioning part 432 is provided on the protruding plate part 47. The positioning part 432 cooperates with the adapter part 431 to position the installation position of the assembly plate 41. A fixing component 45 is also provided between the rear end of the assembly part 1135 facing the housing 1 and the protruding plate part 47. In the assembly, the adapter part 431 is a positioning post, and the positioning part 432 is a positioning hole. The positioning post passes through the positioning hole to form a shaft hole limiting fit. The fixing component 45 includes a fixing post 451 disposed at the rear end of the assembly part 1135, a fixing hole 453 on the protruding plate part 47, and a fixing member 452. One of the fixing post 451 and the fixing member 452 passes through the fixing hole 453, and the two are fixedly connected, for example, by a threaded connection, so as to press and fix the protruding plate part 47 onto the assembly part 1135.

[0102] Optionally, such as Figure 18 As shown, in some embodiments, the mounting plate 41 is provided with a protruding rib 46 on the side facing the first wall 1133, and the protruding rib 46 abuts against the first wall 1133.

[0103] In some embodiments, a rib 46 may be provided on the side of the first wall 1133 facing the mounting plate 41, and the rib 46 abuts against the first wall 1133.

[0104] The protruding rib 46 can make line contact between the assembly plate 41 and the first wall 1133. When the assembly plate 41 shakes relative to the first wall 1133 and produces abnormal noise, the assembly plate 41 and the first wall 1133 make contact through the protruding rib 46. The contact area is small, which can reduce abnormal noise.

[0105] Optionally, in some embodiments, the two end walls 113 are respectively provided with a first drive mechanism 4, and the assembly plates 41 of the two first drive mechanisms 4 have the same structure.

[0106] The assembly plates 41 of the two first drive mechanisms 4 have the same structure, which makes the assembly plates 41 interchangeable, improves the ease of processing the assembly plates 41, and during the assembly process, the operator does not need to distinguish between the left and right parts, further improving manufacturing efficiency.

[0107] It should be noted that when the assembly plates 41 of the two first drive mechanisms 4 are assembled to the housing 1, their arrangement directions can be the same or different.

[0108] In some embodiments, the first drive component 42 includes a power component 421 and a connector 422. The output shaft of the power component 421 is connected to the connector 422. The connector 422 passes through the assembly hole 1136 and the communication hole 412. The swing arm 21 is connected to the connector 422.

[0109] By setting the connector 422, the ease of connection between the power component 421 and the swing arm 21 is improved.

[0110] The power component 421 can be a motor, such as a stepper motor. The power component 421 and the mounting plate 41 can be fixed together with fasteners such as screws.

[0111] Optionally, such as Figures 16 to 18 , Figure 20 As shown, the connector 422 has an anti-detachment part 423, which is in a limiting fit with the wall of the connecting hole 412 (i.e., the side of the mounting plate 41 facing away from the first wall 1133). The anti-detachment part 423 can restrict the position of the connector 422 and improve the ease of assembly.

[0112] Connector 422 can be an insulated shaft, also known as an anti-electric shaft.

[0113] In some embodiments, such as Figures 16 to 18 , Figure 20As shown, the anti-detachment part 423 can be arranged around the connecting hole 412 in a ring. The anti-detachment part 423 can be an anti-detachment disc. The diameter of the anti-detachment part 423 is larger than the diameter of the assembly hole 1136. The anti-detachment part 423 can abut against the side of the assembly plate 41 away from the first wall 1133 to seal the connecting hole 412 and the assembly hole 1136 from the inside, and form a structure that requires mechanical disassembly, reducing the risk of touching the internal live components from the outside and improving the protection performance.

[0114] Optionally, such as Figures 16 to 18 , Figure 20 As shown, the connector 422 can be sleeved on the output shaft of the power component 421 and drivenly connected to the output shaft of the power component 421. The connector 422 and the swing arm 21 can be connected and fixed by snap-fit ​​or the like.

[0115] Optionally, such as Figures 16 to 18 , Figure 20 As shown, the connector 422 has a protruding ring portion 425, which passes through the assembly hole 1136. The outer diameter of the protruding ring portion 425 is smaller than the diameter of the connecting hole 412, and the diameter of the assembly hole 1136 is compatible. After the connector 422 is assembled with the power component 421, the end of the connector 422 connected to the swing arm 21 can pass through the connecting hole 412 and out through the assembly hole 1136. The protruding ring portion 425 passes through the connecting hole 412 and then passes through the assembly hole 1136. The cooperation between the protruding ring portion 425 and the assembly hole 1136 can reduce the gap between the connector 422 and the assembly hole 1136, reduce the possibility of dust and other particles entering the internal space and affecting the first drive mechanism 4, and improve the protective performance.

[0116] The first drive component 42 is connected to a wire harness 424. Optionally, a first wire harness fixing structure 411 may be provided on the assembly plate 41, and the wire harness 424 is fixed by the first wire harness fixing structure 411.

[0117] The first wire harness fixing structure 411 can be a snap-fit, slot, or other structure, and the wire harness 424 can be snapped or interference-fitted to the first wire harness fixing structure 411. One or more first wire harness fixing structures 411 can be provided, and multiple first wire harness fixing structures 411 can be provided at intervals along the wiring path of the wire harness 424.

[0118] By setting the first wire harness fixing structure 411, the wire harness 424 of the first drive component 42 can be fixed, which can prevent the wire harness 424 from being pulled during the assembly process and prevent damage to the power component 421. At the same time, the wiring is pre-fixed, which facilitates the subsequent wiring and reduces the possibility of the wire harness 424 interfering with other components during the assembly process and affecting the assembly efficiency.

[0119] Optionally, a second wire harness fixing structure 161 may be provided inside the housing 1, such as on the face frame 110, and the wire harness 424 is fixed by the second wire harness fixing structure 161.

[0120] The second wire harness fixing structure 161 can be a snap-fit, slot, or other structure, and the wire harness 424 can be snapped or interference-fitted to the second wire harness fixing structure 161. One or more second wire harness fixing structures 161 can be provided, and multiple second wire harness fixing structures 161 can be provided at intervals along the wiring path of the wire harness 424.

[0121] By setting the second wire harness fixing structure 161, the wire harness 424 of the first drive component 42 can be fixed in advance, reducing the risk of wire detachment and subsequent wire pressing during the assembly of the face frame 110 and the chassis 120, and reducing the possibility of the wire harness 424 interfering with other components during the assembly process and affecting the assembly efficiency.

[0122] Optionally, a third wiring harness fixing structure 162 may also be provided on the housing 1, and the wiring harness 424 is fixed by the third wiring harness fixing structure 162 in a detachable manner. The third wiring harness fixing structure 162 can be used to temporarily fix the free end of the wiring harness 424 to reduce interference between the wiring harness 424 and other components during assembly. After the control component (the control component of the air conditioner indoor unit, used to control the operation of the air conditioner indoor unit) is assembled on the housing 1, the free end of the wiring harness 424 is connected to the terminal of the control component, and the wiring harness 424 can be detached from the third wiring harness fixing structure 162.

[0123] The third wire harness fixing structure 162 can be a snap-fit, slot, or other structure, and the wire harness 424 can be snapped or interference-fitted to the third wire harness fixing structure 162. One or more third wire harness fixing structures 162 can be provided, and multiple third wire harness fixing structures 162 can be spaced along the wiring path of the wire harness 424.

[0124] By setting the third wire harness fixing structure 162, the wire harness 424 of the first drive component 42 can be fixed, reducing the possibility that the wire harness 424 may interfere with other components during the assembly process and affect the assembly efficiency.

[0125] It should be noted that in the presence of other wiring harnesses 424, such as the wiring harness 424 of the second drive mechanism 5, the other wiring harnesses 424 can also be fixed by the second wiring harness fixing structure 161 or the third wiring harness fixing structure 162.

[0126] According to some embodiments of this application, optionally, such as Figure 1 and Figure 22 As shown, when the indoor unit of the air conditioner is turned off, the first air guide plate 22 covers part of the air outlet 11.

[0127] In some technologies, in order to obtain a larger air delivery angle, a guide vane is placed at the air outlet 11, which looks rather abrupt when the unit is off. This not only results in poor aesthetic coordination of the air conditioner but also occupies space. Furthermore, because the guide vane is far from the air outlet, its airflow guiding effect is poor, affecting the user's perceived airflow comfort. In this embodiment, the indoor unit of the air conditioner is configured so that the first guide vane 22 can cover the air outlet 11. Within the swing stroke of the first guide vane 22, the distance between the first guide vane 22 and the air outlet 11 can be smaller, which can improve the airflow guiding effect of the first guide vane 22.

[0128] like Figure 23 , Figure 24 As shown, and in combination Figure 29 As shown, the two extreme postures of the swing stroke of the first air guide plate 22 are the first extreme posture and the second extreme posture. In the first extreme posture, the swing arm 21 can be set horizontally, with the end of the swing arm 21 connected to the first air guide plate 22 flush with the rotation center C1 of the swing arm 21. Alternatively, in the first extreme posture, the swing arm 21 is inclined downward from the end connected to the housing 1 to the end connected to the first air guide plate 22, with the end of the swing arm 21 connected to the first air guide plate 22 located below the rotation center C1 of the swing arm 21. That is to say, when the swing arm 21 rotates upward to the first extreme posture, the angle A1 between the swing arm 21 and the upward direction is greater than or equal to 90 degrees.

[0129] By limiting the height of the swing arm 21 to no more than its own rotation center C1, the first air guide plate 22 swings approximately in the area corresponding to the air outlet 11, reducing the possibility of interference between the first air guide plate 22 and the front side 111 of the casing 1. Moreover, the first air guide plate 22 can continue to swing upward without considering avoiding the front side 111 of the casing 1. In this way, the swing arm 21 only needs to satisfy the swing of the first air guide plate 22 in the area corresponding to the air outlet 11, so that when the first air guide plate 22 blocks the first outlet 12, it can smoothly connect with the front side 111 of the casing 1, improving the appearance consistency of the air conditioner indoor unit; and reducing the distance between the first air guide plate 22 and the air outlet 11, improving the airflow guiding effect of the first air guide plate 22.

[0130] It should be noted that the swing arm 21 swings downward in the second extreme posture relative to the first extreme posture.

[0131] Optionally, the swing area of ​​the first air guide plate 22 is located below the upper air outlet boundary 14.

[0132] Optionally, the rotation angle of the swing arm 21 corresponding to the swing stroke of the first air guide plate 22 is greater than or equal to 90 degrees. That is, the included angle A2 between the first extreme posture and the second extreme posture of the swing arm 21 is greater than or equal to 90 degrees.

[0133] For example, when the first air guide plate 22 is in the first extreme posture, the swing arm 21 is set horizontally in the front-to-back direction, and the first air guide plate 22 is set vertically in the up-down direction; when the first air guide plate 22 is in the second extreme posture, the swing arm 21 is set vertically in the up-down direction, and the first air guide plate 22 is set horizontally.

[0134] refer to Figure 1 , Figure 9 and combined Figures 22 to 28 As shown, the indoor unit of the air conditioner may also include a second air guide 3, which includes a second air guide plate 31. The second air guide plate 31 is rotatably connected to the housing 1 and is configured to be able to flip at the air outlet 11.

[0135] The second air guide plate 31 refers to a plate-like structure with airflow guiding function. The second air guide plate 31 can be a closed solid plate, and its surface has an air-guiding effect, meaning that airflow can flow along its surface to adjust the air outlet angle of the air vent 11. The second air guide plate 31 can adjust the air outlet angle of the air vent 11, and when the indoor unit of the air conditioner is off, it can act as a blocking and sealing component for the air outlet 11. The second air guide plate 31 can extend along the length of the air outlet 11 from one end to the other. The second air guide plate 31 can be a flat plate or a curved plate.

[0136] Exemplarily, in some embodiments, the second air guide plate 31 is arranged in a straight line along the length of the air outlet 11. The two side panels of the second air guide plate 31 (the panel refers to the large surface of the second air guide plate 31) are the second inner panel 313 and the second outer panel 314, respectively. The second inner panel 313 is disposed facing the inside of the housing 1, and the second outer panel 314 is disposed facing the outside of the housing 1. The second inner panel 313 is the panel of the second air guide plate 31 facing the inside of the air outlet 11, and the second outer panel 314 is the exposed surface of the second air guide plate 31. The second outer panel 314 can serve as part of the exterior surface of the air conditioner indoor unit. When the airflow flows from the air outlet 11 to the second air guide plate 31, the airflow can flow along the second inner panel 313, which mainly plays a guiding role. The second inner panel 313 can have an arc-shaped structure that bulges slightly outward in the middle along the width direction of the second air guide plate 31, and the main body of the second outer panel 314 can be approximately flat.

[0137] The second air guide plate 31 can be rotatably connected to the housing 1 via the rotating shaft 124, etc. The rotation axis of the second air guide plate 31 can be consistent with the length direction of the housing 1. The second air guide plate 31 can be flipped in the vertical plane to flip to different positions of the air outlet 11, thereby adjusting the air delivery angle.

[0138] For ease of description, the area traversed by the second air guide plate 31 is defined as the rotational stroke of the second air guide plate 31. The rotational stroke of the second air guide plate 31 and the swing stroke of the first air guide plate 22 can be set to be independent of each other, so that the swing of the first air guide plate 22 and the flipping of the second air guide plate 31 can be relatively independent.

[0139] Optionally, the second air guide plate 31 can be connected to the chassis 120. The chassis 120 may also be provided with a component for positioning the second air guide plate 31 in a fourth extreme posture.

[0140] By setting a first air guide plate 22 and a second air guide plate 31, the first air guide plate 22 and the second air guide plate 31 can cooperate to adjust the air delivery angle of the air outlet 11. That is, within the swing stroke of the first air guide plate 22 and the rotation stroke of the second air guide plate 31, the first air guide plate 22 and the second air guide plate 31 can cooperate to adjust the air delivery angle. When the indoor unit of the air conditioner is turned off, the first air guide plate 22 blocks part of the air outlet 11, and the second air guide plate 31 blocks the other part of the air outlet 11. In other words, the first air guide plate 22 and the second air guide plate 31 can cooperate to act as a complete blocking and sealing component for the air outlet 11. Specifically, when the indoor unit of the air conditioner is turned off, the position of the first air guide plate 22 is within the swing stroke of the first air guide plate 22, and the position of the second air guide plate 31 is also within the rotation stroke of the second air guide plate 31.

[0141] It should be noted that the length direction of the air outlet 11, the length direction of the casing 1, the length direction of the first air guide plate 22, and the length direction of the second air guide plate 31 can be understood as being in the same direction. In a wall-mounted indoor unit, the length direction usually corresponds to the left-right direction of the casing 1 (the left-right, front-back, and up-down directions of the casing 1 are all defined based on the usage state when the air conditioner indoor unit is assembled indoors). The width direction of the first air guide plate 22 and the width direction of the second air guide plate 31 can be understood as the extension length of each air guide plate along the width direction of the air outlet 11, which is approximately perpendicular to the aforementioned length direction.

[0142] According to the indoor unit of the air conditioner of this application, the swing arm 21 of the first air guide 2 is rotatably connected to the casing 1 to form a lever fulcrum, so that the first air guide plate 22 can swing around the air outlet 11 under the drive of the swing arm 21 to adjust the air supply angle; the second air guide plate 31 can adjust the air supply angle by flipping. In this way, the first air guide plate 22 and the second air guide plate 31 can be adjusted in various ways by cooperating with each other. At the same time, when the indoor unit of the air conditioner is turned off, the first air guide plate 22 and the second air guide plate 31 respectively block part of the air outlet 11, which can reduce the possibility of dust entering. The first air guide plate 22 and the second air guide plate 31 can both serve as the exterior surfaces of the air conditioner indoor unit, reducing the abruptness of the first air guide plate 22 and the second air guide plate 31 relative to the casing 1 and improving the appearance consistency and integrity of the air conditioner indoor unit. Furthermore, since the first air guide plate 22 and the second air guide plate 31 can cover the air outlet 11, the distance between the first air guide plate 22 and the air outlet 11 and the distance between the second air guide plate 31 and the air outlet 11 can be smaller within the swing stroke of the first air guide plate 22 and the rotation stroke of the second air guide plate 31, which can improve the airflow guiding effect of the first air guide plate 22 and the second air guide plate 31.

[0143] Alternatively, in some implementations, such as Figure 1 , Figure 2 and Figure 22 As shown, when the indoor unit of the air conditioner is turned off, the first air guide plate 22 can cover the first outlet 12, and the second air guide plate 31 can cover the second outlet 13. The first air guide plate 22 is driven to swing by the swing arm 21 and moves to cover the first outlet 12 on the front side when the unit is turned off. At this time, the first air guide plate 22 can connect with the front side 111 of the casing 1. The second air guide plate 31 is rotated to cover the second outlet 13 on the bottom side when the unit is turned off by flipping. The second air guide plate 31 can connect with the bottom side of the casing 1. In this way, the first air guide plate 22 and the second air guide plate 31 can not only cover the air outlet 11, but also make the appearance of the indoor unit of the air conditioner more natural when it is turned off.

[0144] For example, the indoor unit of the air conditioner is a wall-mounted indoor unit, such as... Figure 1 , Figure 2 and Figure 22 As shown, in the off state, the first air guide plate 22 blocks the first outlet 12, and the second air guide plate 31 blocks the second outlet 13. The width direction of the first air guide plate 22 is roughly parallel to the front side 111 of the housing 1, and the first air guide plate 22 is set roughly in the up-down direction (vertical direction). The width direction of the second air guide plate 31 is roughly parallel to the bottom surface 112 of the housing 1, and the second air guide plate 31 is set roughly in the horizontal direction.

[0145] refer to Figure 1 , Figure 2 and Figure 22 As shown, in some embodiments, when the indoor unit of the air conditioner is in the off state, with the first air guide plate 22 blocking the first outlet 12 and the second air guide plate 31 blocking the second outlet 13, the first air guide plate 22 can block the front side of the second air guide plate 31. When the indoor unit of the air conditioner is in the off state, when viewed from the front of the indoor unit, the second air guide plate 31 can be blocked by the first air guide plate 22, resulting in better appearance consistency and overall integrity, and improving aesthetics.

[0146] According to some embodiments of this application, optionally, such as Figure 1 , Figure 2 and Figure 22 As shown, when the indoor unit of the air conditioner is turned off, and the first air guide plate 22 blocks the first outlet 12 and the second air guide plate 31 blocks the second outlet 13, the first air guide plate 22 is flush with the front side 111 of the casing 1 when the air outlet 11 is turned off; and / or, the second air guide plate 31 is flush with the bottom surface 112 of the casing 1 when the unit is turned off.

[0147] The first air guide plate 22 is flush with the front side 111 of the casing 1. This can be understood as the outer side of the first air guide plate 22 (i.e., the first outer panel 222) being approximately flush with the front side 111 of the casing 1. In the off state, the main body of the first outer panel 222 can be configured to be approximately coplanar with the front side 111 of the casing 1. In other words, the first air guide plate 22 smoothly connects with the front side 111 of the casing 1 in the off state, thereby improving the appearance consistency and overall integrity of the indoor air conditioning unit in the off state. The shape of the first outer panel 222 can be matched with the shape of the front side 111 of the casing 1 to further improve the appearance consistency of the indoor air conditioning unit.

[0148] The second air guide plate 31 is flush with the bottom surface 112 of the casing 1. This can be understood as the bottom-facing surface of the second air guide plate 31 (refer to the second outer panel 314) being approximately flush with the bottom surface 112 of the casing 1. The main body of the second outer panel 314 is approximately coplanar with the bottom surface 112 of the casing 1. In other words, the second air guide plate 31 smoothly connects to the bottom surface 112 of the casing 1 in the off state, thus improving the appearance consistency and overall integrity of the casing 1 in the off state. The shape of the second outer panel 314 can be matched to the shape of the bottom surface 112 of the casing 1 to improve the appearance consistency of the indoor air conditioning unit.

[0149] In some embodiments, in order to improve the aesthetics and appearance consistency of the air conditioner indoor unit, the bottom of the first outer panel 222 corresponding to the off state can be set to an inwardly gradually curved shape; the two ends of the second outer panel 314 can be set to a gently transitioning chamfer.

[0150] It should be noted that two relatively flat items can be considered flat as long as they are roughly flat. Specifically, they can be considered flat if they are within the allowable deviation range of processing error, or if the user perceives them as flat to the naked eye.

[0151] It should also be noted that in some other implementations, such as Figure 5 As shown, the indoor unit of the air conditioner can also be configured such that, when the indoor unit is off, the second air guide plate 31 blocks the first outlet 12, and the first air guide plate 22 blocks the second outlet 13. In this implementation, when the unit is off, the second air guide plate 31 located at the front can also block the front of the first air guide plate 22 to improve the appearance consistency of the indoor unit; or, as shown... Figure 5 As shown, in the off state, the first air guide plate 22 located on the bottom side can cover the bottom side of the second air guide plate 31 on the front side to improve the appearance consistency of the indoor unit of the air conditioner. In addition, in the off state, the second outer plate surface 314 of the second air guide plate 31 can be flush with the front side surface 111 of the casing 1, and the first outer plate surface 222 of the first air guide plate 22 can also be flush with the bottom surface 112 of the casing 1.

[0152] Optionally, in some embodiments, the swing stroke of the first air guide plate 22 is located outside the rotation stroke of the second air guide plate 31. That is, the first air guide plate 22 can be located on the side of the second air guide plate 31 that is away from the inside of the housing 1.

[0153] The first air guide plate 22 driven by the swing arm 21 is placed outside the flipped second air guide plate 31. The swing arm 21, the first air guide plate 22 and other components are less likely to interfere with each other with the internal components of the housing 1. The first air guide plate 22 can have a large swing range, and the air supply requirements of multiple modes can be met by the cooperation of the first air guide plate 22 and the second air guide plate 31.

[0154] In some embodiments, the width L1 of the first air guide plate 22 is set to be greater than the width L2 of the second air guide plate 31.

[0155] For example, such as Figures 2 to 4 and combined Figures 21 to 28 As shown, when the machine is off, with the first air guide plate 22 blocking the first outlet 12 and the second air guide plate 31 blocking the second outlet 13, the width L1 of the first air guide plate 22 is set to be greater than the width L2 of the second air guide plate 31.

[0156] The width L1 of the first air guide plate 22 refers to the straight-line distance between its two opposite edges along its width direction. The width L2 of the second air guide plate 31 refers to the straight-line distance between its two opposite edges along its width direction. The first air guide plate 22 and the second air guide plate 31 can be set to approximately equal width along their length direction. When the first air guide plate 22 and / or the second air guide plate 31 are set to unequal widths along their length direction, the width L1 of the first air guide plate 22 can be the maximum width of the first air guide plate 22, and the width L2 of the second air guide plate 31 can be the maximum width of the second air guide plate 31.

[0157] The width L2 of the second air guide plate 31 is smaller than the width L1 of the first air guide plate 22. This reduces the possibility of interference between the widths L1 and L2 of the first air guide plate 22 and the second air guide plate 31, allowing the second air guide plate 31 to better avoid the swing path of the first air guide plate 22. Simultaneously, the first air guide plate 22 can also better avoid the rotation path of the second air guide plate 31. In the off state, when the first air guide plate 22 is blocked by the first outlet 12 and the second air guide plate 31 is blocked by the second outlet 13, the width L2 of the second air guide plate 31 is smaller than the width L1 of the first air guide plate 22. This also helps the first air guide plate 22 to form a front shield for the second air guide plate 31, improving the appearance consistency and overall integrity of the indoor unit.

[0158] Optionally, in some embodiments, the width L1 of the first air guide plate 22 and the width L2 of the second air guide plate 31 satisfy: 0.9 < L2 / L1 < 1.

[0159] Specifically, the L2 / L1 ratio can be 0.91, 0.92, 0.95, 0.96, 0.97, 0.98, 0.99, etc.

[0160] By ensuring that the width ratio of the first air guide plate 22 and the second air guide plate 31 is close to 1, the first air guide plate 22 and the second air guide plate 31 can be made more consistent in appearance while reducing mutual interference, thus improving the user's visual experience. At the same time, the near-1 width ratio of the first air guide plate 22 and the second air guide plate 31 means that, in the off state, the misalignment at the joint of the first air guide plate 22 and the second air guide plate 31 can be controlled to a visually imperceptible range, improving the appearance consistency and overall integrity of the air conditioner indoor unit.

[0161] Optionally, the air outlet 11 is located at the bottom front of the housing 1. The air outlet 11 has an upper air outlet boundary 14 on the upper side and a lower air outlet boundary 15 on the lower side. The vertical dimension L3 of the upper air outlet boundary 14 and the lower air outlet boundary 15 is smaller than the longitudinal dimension L4 of the upper air outlet boundary 14 and the lower air outlet boundary 15.

[0162] For example, such as Figures 2 to 4 and combined Figures 21 to 28 As shown, in the off state, the first air guide plate 22 blocks the first outlet 12, and the second air guide plate 31 blocks the second outlet 13. The width L1 of the first air guide plate 22 is set to be greater than the width L2 of the second air guide plate 31. The dimension L3 of the upper air outlet boundary 14 and the lower air outlet boundary 15 along the vertical direction is smaller than the dimension L4 of the upper air outlet boundary 14 and the lower air outlet boundary 15 along the front-back direction.

[0163] The front bottom of the casing 1 refers to the area at the lower front of the casing 1, which can be understood by referring to the location of the first outlet 12 and the second outlet 13. The vertical direction can be understood as the vertical direction, and the front-back direction is roughly parallel to the horizontal direction.

[0164] The upper air outlet boundary 14 can be understood by referring to the upper edge of the air outlet 11 enclosed by the housing 1, and the lower air outlet boundary 15 can be understood by referring to the lower edge of the air outlet 11 enclosed by the housing 1. The vertical dimension L3 of the upper air outlet boundary 14 and the lower air outlet boundary 15 can be understood as the vertical dimension of the air outlet 11, that is, the vertical width of the air outlet 11. The horizontal dimension L4 of the upper air outlet boundary 14 and the lower air outlet boundary 15 can be understood as the horizontal dimension of the air outlet 11, that is, the horizontal width of the air outlet 11.

[0165] The size L3 of the air outlet 11 is smaller than the size L4, which can reduce the possibility of interference between the width L1 of the first air guide plate 22 and the width L2 of the second air guide plate 31. This is beneficial to make the movement between the first air guide plate 22 and the second air guide plate 31 completely independent. The second air guide plate 31 can better avoid the swing path of the first air guide plate 22. At the same time, the first air guide plate 22 can also better avoid the rotation path of the second air guide plate 31.

[0166] Optionally, the vertical dimension L3 of the upper air outlet boundary 14 and the lower air outlet boundary 15 and the front-back dimension L4 of the upper air outlet boundary 14 and the lower air outlet boundary 15 satisfy the condition 1.5 < L4 / L3 < 1.8.

[0167] Specifically, the L4 / L3 ratio can be set to 1.51, 1.55, 1.6, 1.65, 1.7, 1.75, 1.79, etc.

[0168] The constraint relationship between the dimensions L4 and L3 of the air outlet 11 can reduce the possibility of interference between the width L1 of the first air guide plate 22 and the width L2 of the second air guide plate 31, while increasing the area of ​​the air outlet 11 and the air delivery angle. This is beneficial to make the movement between the first air guide plate 22 and the second air guide plate 31 completely independent.

[0169] Optionally, in some embodiments, the width L1 of the first air guide plate 22 is smaller than the front-to-back dimension L4 of the upper air outlet boundary 14 and the lower air outlet boundary 15. This can reduce the possibility of interference between the first air guide plate 22 and the lower air outlet boundary 15 when the first air guide plate 22 swings downward.

[0170] Optionally, 30 mm < L4 - L1 < 50 mm, that is, the difference between the dimension L4 of the upper air outlet boundary 14 and the lower air outlet boundary 15 in the front-back direction and the width L1 of the first air guide plate 22 is between 30 mm and 50 mm. Specifically, L4 can be 30.1 mm, 31 mm, 35 mm, 40 mm, 45 mm, 49 mm, or 49.9 mm larger than L1.

[0171] The setting range of the difference between the dimension L4 of the upper air outlet boundary 14 and the lower air outlet boundary 15 along the front-back direction and the width L1 of the first air guide plate 22 can reduce the possibility of interference between the first air guide plate 22 and the lower air outlet boundary 15 when the first air guide plate 22 swings downward, and can also reduce the size difference between the first air guide plate 22 and the air outlet 11, thereby improving the visual consistency of the air conditioner indoor unit.

[0172] Optionally, in some embodiments, the vertical dimension L3 of the upper air outlet boundary 14 and the lower air outlet boundary 15 can be slightly larger than the width L1 of the first air guide plate 22. Specifically, L3 can be 1 mm to 2 mm larger than L1. In this way, when the first air guide plate 22 is blocked by the first outlet 12, the lower edge of the second air guide plate 31 does not protrude from the bottom surface 112 of the housing 1, improving the appearance consistency and integrity of the indoor unit of the air conditioner.

[0173] In other embodiments, the width L1 of the first air guide plate 22 can be set to be smaller than the width L2 of the second air guide plate 31, and the dimension L3 of the upper air outlet boundary 14 and the lower air outlet boundary 15 along the vertical direction can be larger than the dimension L4 of the upper air outlet boundary 14 and the lower air outlet boundary 15 along the front-back direction. For example, as... Figures 5 to 7 As shown, when the indoor unit of the air conditioner is turned off, and the second air guide plate 31 blocks the first outlet 12 and the first air guide plate 22 blocks the second outlet 13, the width L1 of the first air guide plate 22 is set to be smaller than the width L2 of the second air guide plate 31, and the dimension L3 of the upper air outlet boundary 14 and the lower air outlet boundary 15 along the vertical direction is set to be larger than the dimension L4 of the upper air outlet boundary 14 and the lower air outlet boundary 15 along the front-back direction.

[0174] Optionally, in some embodiments, the air outlet 11 includes a first outlet portion 12 and a second outlet portion 13, and the two extreme postures of the swing stroke of the first air guide plate 22 are the first extreme posture and the second extreme posture, respectively. Figure 2 , Figure 4 , Figure 7 , Figure 22 , Figure 27 , Figure 28 As shown, in the first extreme posture, the first air guide plate 22 blocks the first outlet 12, as... Figure 3 , Figure 5 , Figure 6 , Figure 24 , Figure 26 As shown, in the second extreme posture, the first air guide plate 22 is located below the second outlet section 13.

[0175] The first air guide plate 22 can swing between a first extreme posture and a second extreme posture. The stroke of the first air guide plate 22 between the first extreme posture and the second extreme posture is the swing stroke. The extreme posture of the first air guide plate 22 limits the swing stroke of the first air guide plate 22, and the swing stroke of the first air guide plate 22 can meet the air delivery angle requirements under different operating conditions.

[0176] In the first extreme posture, the first air guide plate 22 can be set approximately vertically; in the second extreme posture, the first air guide plate 22 can be set approximately horizontally, or the first air guide plate 22 can also be set as follows: Figure 26 The tilt setting is shown.

[0177] It should be noted that, in the second extreme posture, the first air guide plate 22 is located below the air outlet 11 at any position, or more precisely, below the bottom surface 112 of the housing 1. Specifically, in the off state, when the first air guide plate 22 blocks the first outlet 12 and the second air guide plate 31 blocks the second outlet 13, the first extreme posture of the first air guide plate 22, when it is set approximately vertically, can be considered its posture in the off state. Conversely, in the off state, when the first air guide plate 22 blocks the second outlet 13 and the second air guide plate 31 blocks the first outlet 12, the second extreme posture of the first air guide plate 22, when it is set approximately horizontally, can be considered its posture in the off state.

[0178] Optionally, in the first extreme posture, the end of the swing arm 21 connected to the first air guide plate 22 is flush with the rotation center C1 of the swing arm 21, or the end of the swing arm 21 connected to the first air guide plate 22 is located below the rotation center C1 of the swing arm 21.

[0179] The rotation center C1 of the swing arm 21 can be understood by referring to the rotation axis 124 of the swing arm 21.

[0180] It should be noted that the maximum rotation angle of the swing arm 21 is limited by the first limit posture and the second limit posture. The first limit posture has been explained above. The limit position of the first air guide plate 22 swinging downward (i.e. the limit position of the second limit posture) is in contact with the bottom surface 112 of the housing 1.

[0181] The swing stroke of the first air guide plate 22 can reduce the possibility of interference between the first air guide plate 22 and the housing 1, and can also roughly cover the entire air outlet 11 area, thus improving the adaptability of the first air guide plate 22 to various modes.

[0182] According to some embodiments of this application, optionally, the second air guide plate 31 has two opposite ends along its width direction, defined as the first end 311 and the second end 312, and the two extreme postures of the rotation stroke of the second air guide plate 31 are the third extreme posture and the fourth extreme posture, respectively. Figure 3 , Figure 6 ( Figure 6 The direction of the arrow indicates the direction of airflow. Figure 23 As shown, and in combination Figure 30 In the third extreme posture, the second end 312 is located below the first end 311, and the second end 312 is located in front of the first end 311, forming an air outlet gap with the upper air outlet boundary 14; as Figure 4 ( Figure 4 The direction of the arrow indicates the direction of airflow. Figure 7 ( Figure 7 The arrow direction indicates the direction of airflow. Figure 26 As shown, and in combination Figure 30 In the fourth extreme posture, the second end 312 is located above the first end 311 and behind the first end 311, and the first end 311 forms an air outlet gap with the lower air outlet boundary 15.

[0183] The air outlet gap can be understood as the area where airflow actually flows out from the casing 1.

[0184] In the third extreme posture, the first end 311 is the end of the second air guide plate 31 closest to the impeller 7 of the indoor fan, and the second end 312 is the end furthest from the impeller 7. The second air guide plate 31 guides the airflow forward and upward. At this time, the first air guide plate 22 can be swung to avoid the air outlet gap formed by the second end 312 and the upper air outlet boundary 14. The third extreme posture can form the maximum airflow angle of the indoor air conditioning unit and can be used as the default cooling angle. In the third extreme posture, the second air guide plate 31 can be parallel to the lower profile line 17 of the air duct 16 near the air outlet 11, that is, the airflow flows out of the casing 1 roughly along the direction of the air duct 16.

[0185] In the fourth extreme posture, the second end 312 is the end of the second air guide plate 31 that is close to the impeller 7 of the indoor fan, and the first end 311 is the end that is far away from the impeller 7. The second air guide plate 31 forms a forward and downward guiding effect on the airflow.

[0186] The second air guide plate 31 can flip between the third and fourth extreme positions. The stroke of the second air guide plate 31 between the third and fourth extreme positions is the rotation stroke. The extreme positions of the second air guide plate 31 limit the flip stroke of the second air guide plate 31, which can improve the adaptability of the indoor air conditioning unit to various air supply angle requirements.

[0187] refer to Figure 23 As shown, optionally, the vertical dimension of the upper air outlet boundary 14 and the lower air outlet boundary 15 is A. In the third extreme posture, the vertical dimension between the upper air outlet boundary 14 and the second end 312 is a1, and the value of a1 ranges from 95%A to 115%A. The vertical dimension between the first end 311 and the second end 312 is B, and B satisfies 30 mm ≤ B ≤ 45 mm.

[0188] a1 can be set to 95%A, 96%A, 97%A, 100%A, 105A, 110%A, 115%A, etc.

[0189] B can be set to 30 mm, 31 mm, 35 mm, 38 mm, 40 mm, 45 mm, etc. Among them, the smaller the value of B, the smaller the tilt angle of the second air guide plate 31.

[0190] By using the vertical dimension a1 between the upper air outlet boundary 14 and the second end 312 and the vertical dimension B between the first end 311 and the second end 312 of the air guide plate, the tilt angle of the second air guide plate 31 and the actual opening of the air outlet can be limited. The corresponding dimension limitation in this embodiment can increase the maximum exhaust volume of the air conditioner indoor unit and improve the user's satisfaction with the cooling mode.

[0191] Optionally, such as Figure 30 As shown, the rotation angle A3 corresponding to the rotation stroke of the second air guide plate 31 is 150 degrees to 180 degrees.

[0192] The rotation angle A3 corresponding to the rotation stroke of the second air guide plate 31 can be referenced to the rotation angle of the same part of the second air guide plate 31 (e.g., the first end 311 or the second end 312) between the third limit posture and the fourth limit posture.

[0193] For example, the rotation angle A3 corresponding to the rotation stroke of the second air guide plate 31 can be set to 150 degrees, 155 degrees, 160 degrees, 165 degrees, 170 degrees, 175 degrees and 180 degrees.

[0194] It should be noted that the third extreme attitude of the second air guide plate 31 has been defined above. Given the third extreme attitude, the fourth extreme attitude of the second air guide plate 31 can be derived by defining the rotation angle A3 corresponding to the rotation stroke of the second air guide plate 31.

[0195] The second air guide plate 31 can be flipped inside the air outlet 11, and the second air guide plate 31 does not interfere with the housing 1 or the internal functional components. The rotation angle A3 of the second air guide plate 31 can make the second air guide plate 31 and the air outlet 11 form multiple air delivery angles, which improves the adaptability of the second air guide plate 31 to various modes and can meet the user's multiple air delivery angle requirements.

[0196] Optionally, the indoor unit of the air conditioner in this embodiment may have a preset cooling mode (i.e., the default cooling mode in the default on state). For example... Figures 2 to 7 and combined Figures 22 to 28 The swing stroke of the first air guide plate 22 is located outside the rotation stroke of the second air guide plate 31, such as... Figure 3 , Figure 6 , Figure 23 ( Figure 23 As shown by the arrow indicating the airflow path, in the preset cooling mode, the second air guide plate 31 is in the third extreme posture, and the first air guide plate 22 avoids the air outlet gap formed by the second end 312 and the upper air outlet boundary 14.

[0197] like Figure 2 and Figure 3 As shown, in the off state, with the first air guide plate 22 blocking the first outlet 12 and the second air guide plate 31 blocking the second outlet 13, when the indoor unit of the air conditioner is turned on in the preset cooling mode, the first air guide plate 22 opens clockwise and can rotate to below the second air guide plate 31, leaving the second air guide plate 31 unobstructed, thus maximizing airflow. In other words, when switching from off to on cooling mode, the second air guide plate 31 swings from its first extreme position to its second extreme position, rotating clockwise from the off state to its second extreme position, reaching the default cooling angle. The positions of the first air guide plate 22 and the second air guide plate 31 in the preset cooling mode can increase airflow and improve cooling efficiency. Figure 5 and Figure 7 As shown, in the off state, with the first air guide plate 22 blocking the second outlet 13 and the second air guide plate 31 blocking the first outlet 12, when the indoor unit of the air conditioner starts the preset cooling mode, the first air guide plate 22 rotates clockwise to guide the cooling airflow.

[0198] Optionally, such as Figure 23As shown, in the preset cooling mode, the first air guide plate 22 is in the second extreme posture or the posture of being turned off, so as to avoid the air outlet gap formed between the second end 312 and the upper air outlet boundary 14.

[0199] like Figure 3 , Figure 6 and Figure 23 As shown, the indoor unit of the air conditioner in this embodiment can have a maximum air volume mode. In the maximum air volume mode, the second end 312 of the second air guide plate 31 is located below the first end 311 and the second end 312 is located in front of the first end 311. The second end 312 and the upper air outlet boundary 14 form an air outlet gap. The first air guide plate 22 is configured to avoid the air outlet gap formed between the second end 312 and the upper air outlet boundary 14.

[0200] The maximum airflow mode can be applied to the cooling mode, and in some cases, it can also be applied to the heating mode. The posture of the first air guide plate 22 and the second air guide plate 31 in the maximum airflow mode can be the same as in the preset cooling mode.

[0201] Optionally, the indoor unit of the air conditioner in this embodiment may have a first preset anti-direct-blow mode, which may be the mode corresponding to activating the anti-direct-blow function in cooling mode. Figure 24 ( Figure 24 As shown by the arrow indicating the airflow path, the swing stroke of the first air guide plate 22 is located outside the rotation stroke of the second air guide plate 31. In the first anti-direct-blow mode, the second end 312 of the second air guide plate 31 is located above and in front of the first end 311, forming an air outlet gap with the upper air outlet boundary 14. The first air guide plate 22 is configured to avoid the air outlet gap formed by the second end 312 and the upper air outlet boundary 14. That is to say, in the first anti-direct-blow mode, the first air guide plate 22 avoids the air outlet gap, and the second air guide plate 31 guides the airflow to an upward oblique outlet to reduce the possibility of the airflow blowing towards the user.

[0202] Optionally, in the first preset anti-direct-blow mode, the first air guide plate 22 is in the second extreme posture or the posture of being turned off, so as to avoid the air outlet gap formed between the second end 312 and the upper air outlet boundary 14.

[0203] Optionally, continue to refer to Figure 24 As shown, the vertical dimension of the upper air outlet boundary 14 and the lower air outlet boundary 15 is A. In the first preset anti-direct blowing mode, the vertical dimension between the upper air outlet boundary 14 and the second end 312 is a2, and the value of a2 ranges from 65%A to 75%A.

[0204] For example, the value of a2 can be 65%A, 68%A, 70%A, 72%A, or 75%A.

[0205] In the first preset anti-direct-blow mode, the constraint of dimension a2 in the vertical direction between the upper air outlet boundary 14 and the second end 312 can reduce the possibility of condensation on the upper air outlet boundary 14 caused by airflow blowing on it in the cooling state.

[0206] Optionally, the indoor unit of the air conditioner in this embodiment may have a preset circulating gentle air mode. For example... Figure 25 ( Figure 25 As shown by the arrow indicating the airflow path, in the preset circulating soft wind mode, the second air guide plate 31 reciprocates within its rotation stroke. In the preset circulating soft wind mode, the second air guide plate 31 reciprocates around its own rotation center C2 (which can be understood by referring to the rotation axis of the second air guide plate 31), causing the airflow delivered from the air duct 16 to be quickly cut and accelerated at the end of the air outlet, thereby forming multiple short-lived and directional airflows, thus achieving the effect of providing a cooling sensation even without wind.

[0207] It should be noted that the preset circulating gentle wind mode can be applied to both cooling and heating modes of the indoor unit of the air conditioner. In other words, the preset circulating gentle wind mode can be activated regardless of whether the unit is in cooling or heating mode. Since the second air guide plate 31 cannot completely cover the air outlet 11, it can be positioned arbitrarily in the preset circulating gentle wind mode. However, the position of the second air guide plate 31 will still affect the cooling or heating efficiency.

[0208] In some embodiments, the swing stroke of the first air guide plate 22 is located outside the rotation stroke of the second air guide plate 31. In a preset circulating gentle breeze mode, the first air guide plate 22 can be set to an intermediate posture between the first extreme posture and the second extreme posture. For example, as shown... Figure 25 As shown, the first air guide plate 22 can be positioned at the midpoint of its swing stroke, that is, at the position where the first air guide plate 22 rotates halfway from the first extreme posture to the second extreme posture. In this way, the first air guide plate 22 can provide secondary shielding for the airflow guided by the second air guide plate 31, reducing the wind sensation and improving the user experience. At the same time, there are air outlet gaps on both sides of the first air guide plate 22, which can reduce the impact of the first air guide plate 22 on airflow diffusion and improve cooling and heating efficiency.

[0209] Optionally, the indoor unit of the air conditioner in this embodiment may have a preset jet flow mode. For example... Figure 26 As shown, the swing stroke of the first air guide plate 22 is located outside the rotation stroke of the second air guide plate 31. In the preset jet mode, the second air guide plate 31 is in the fourth limit posture, and the first air guide plate 22 is located below the second air guide plate 31. An air supply gap is formed between the first end 311 and the first air guide plate 22.

[0210] It should be noted that the preset jet mode can be applied to both the cooling and heating modes of the indoor unit of the air conditioner. In other words, the preset jet mode can be activated regardless of whether the unit is in cooling or heating mode.

[0211] In the preset jet flow mode, the airflow can be pressed downwards by the second air guide plate 31, and with the guiding effect of the first air guide plate 22 below the second air guide plate 31, the airflow can be delivered to the user's designated location. Specifically, in the preset jet flow mode, the first air guide plate 22 can be set to a selectively fixed angle below the second air guide plate 31; the first air guide plate 22 can also be set to a reciprocating oscillating motion in the area below the second air guide plate 31, thereby changing the air outlet angle and efficiently and accurately delivering the airflow to the designated location.

[0212] In the preset jet mode, the airflow can be efficiently and accurately delivered to the designated location through the air duct 16. When a user needs to quickly cool or warm an object or himself, he can use the jet mode to direct the airflow directly to himself or the object.

[0213] Optionally, the indoor unit of the air conditioner in this embodiment may have a preset heating mode. The preset heating mode can be considered as a powerful heating mode or a heating mode automatically defaulted to when the unit is turned on. For example... Figure 4 , Figure 7 and Figure 27 As shown, the swing stroke of the first air guide plate 22 is located outside the rotation stroke of the second air guide plate 31. The first air guide plate 22 is in the first limit posture (which can also be considered as the posture corresponding to the power off state). The second end 312 of the second air guide plate 31 is located above the first end 311. The first end 311 and the lower air outlet boundary 15 form an air outlet gap.

[0214] Optionally, in the preset heating mode, such as Figure 4 and Figure 7 As shown, the second end 312 can be located behind the first end 311. Figure 2 and Figure 4 As shown, in the off state, with the first air guide plate 22 blocking the first outlet 12 and the second air guide plate 31 blocking the second outlet 13, when the indoor unit of the air conditioner is turned on in the preset heating mode, the first air guide plate 22 remains off, and the second air guide plate 31 rotates counterclockwise to the heating angle to compress and guide the airflow. Because the first air guide plate 22 blocks the upper part of the airflow, the airflow for heating is more singular and there is no channel for overflowing fluid. Figure 5 and Figure 7As shown, in the off state, with the first air guide plate 22 blocking the second outlet 13 and the second air guide plate 31 blocking the first outlet 12, when the indoor unit of the air conditioner starts the preset heating mode, the first air guide plate 22 rotates counterclockwise to the heating angle, and the second air guide plate 31 can rotate or remain off. Because the first air guide plate 22 blocks the upper part of the air field, the air field for heating downward pressure is more singular and there is no channel for overflow fluid.

[0215] In other implementations, such as Figure 27 As shown, in the preset heating mode, the line connecting the second end 312 and the first end 311 is parallel to the vertical direction, or the second end 312 is located in front of the first end 311 and the angle β1 between the line connecting the second end 312 and the first end 311 and the vertical direction is greater than 0 degrees and less than or equal to 10 degrees. For example, the angle β1 can be 1 degree, 2 degrees, 4 degrees, 5 degrees, 6 degrees, 8 degrees, and 10 degrees. Taking the case where the first air guide plate 22 blocks the first outlet 12 and the second air guide plate 31 blocks the second outlet 13 in the off state as an example, when the preset heating mode is activated, the first air guide plate 22 rotates to the position corresponding to the off state (the position corresponding to the first extreme posture), and the second air guide plate 31 rotates to a vertical setting or forms a certain angle β1 with the vertical angle, which can achieve negative angle air delivery, realize the wall-mounted airflow heating effect, and improve the user experience.

[0216] Optionally, the indoor unit of the air conditioner in this embodiment may have a second preset anti-direct-blow mode. The second preset anti-direct-blow mode can be considered as a mode in which the anti-direct-blow function is activated during heating. For example... Figure 28 As shown, the swing stroke of the first air guide plate 22 is located outside the rotation stroke of the second air guide plate 31. In the second preset anti-direct blowing mode, the first air guide plate 22 is in the first extreme posture, the first end 311 forms an air outlet gap with the lower air outlet boundary 15, the second end 312 is located above the first end 311 and in front of the first end 311, and the angle β2 between the line connecting the second end 312 and the first end 311 and the vertical direction is greater than or equal to 10 degrees and less than or equal to 25 degrees.

[0217] For example, the included angle β2 can be 10 degrees, 12 degrees, 14 degrees, 15 degrees, 16 degrees, 18 degrees, 20 degrees, or 25 degrees.

[0218] In the second preset anti-direct-blow mode, the included angle β2 is greater than the included angle β1 in the preset heating mode, which can achieve the function of preventing direct blow in the upper part and improve the user experience.

[0219] It should be noted that the posture or position limitation of the first air guide plate 22 and the second air guide plate 31 in the above mode is only a preset posture or position in the preset mode. In actual use, the user can manually adjust the posture or position of the first air guide plate 22 and the second air guide plate 31 in each mode, selectively making the first air guide plate 22 at any position or posture within its swing stroke, and selectively making the second air guide plate 31 at any posture or position within its rotation stroke.

[0220] The second air guide 3 also includes a second drive mechanism 5, which can be installed on the housing 1, specifically on the chassis 120 and connected to the second air guide plate 31, for driving the second air guide plate 31 to rotate.

[0221] A second drive mechanism 5 can be provided and located at the end of the chassis 120 connected to the end wall 113. The second drive mechanism 5 may include a motor and a rotating shaft 124. The motor may be located on the side of the chassis 120 away from the air outlet 11. For example, the motor of the second drive mechanism 5 may be provided in the accommodating space 1131 and installed on the side of the chassis 120 facing the accommodating space 1131. The motor is connected to the rotating shaft 124, and the rotating shaft 124 passes through the end of the chassis 120 and is connected to the second air guide plate 31.

[0222] The chassis 120 may also have multiple support frames 122, and the support frames 122 are provided with rotating shafts 123. The second air guide plate 31 is provided with multiple hinge parts 32. The rotating shafts 124 and 123 are connected to the hinge parts 32 at corresponding positions. The rotating shafts 124 and 123 are coaxially arranged and rotate around the rotating shafts 124 and 123 under the driving action of the second driving mechanism 5.

[0223] This application also provides an air conditioner, including the indoor unit of the air conditioner proposed in this application or any embodiment of this application.

[0224] An air conditioner may also include an outdoor unit, which includes a compressor, an outdoor heat exchanger, an expansion valve, a four-way valve, etc. The compressor, the outdoor heat exchanger, the expansion valve, the four-way valve, and the indoor heat exchanger are connected by refrigerant pipes to form a refrigeration / heating system.

[0225] The air conditioner in this embodiment has the same beneficial effects as the indoor air conditioner proposed in this application or any embodiment of this application.

[0226] Unless otherwise specified, all embodiments and optional embodiments of this application can be combined to form new technical solutions.
