Description

Technical Field

[0001] The present application relates to the technical field of air conditioning, and in particular to an air conditioning indoor unit. Background Art

[0002] At present, an air guide plate is usually provided at the air outlet of the casing of the air conditioner indoor unit. The air guide plate can not only adjust the direction of air when it is output from the casing air outlet to the indoor room, but also when the air conditioner indoor unit is not working, the air guide plate can close the casing air outlet to maintain the aesthetics of the air conditioner indoor unit, while also preventing dust and the like from entering the casing through the casing air outlet.

[0003] In a wall-mounted air conditioner indoor unit, the air guide plate is rotatable along the length direction of the casing to open or close the casing air outlet, and the two ends of the air guide plate along the length direction of the casing are arranged one-to-one with the two side edges of the casing air outlet that are arranged opposite to each other along the length direction of the casing, and there is a matching gap between the end of the air guide plate and the edge corresponding to the casing air outlet to ensure reliable rotation of the air guide plate. During the rotation of the air guide plate, it is inevitable that the air guide plate will deviate along the length direction of the casing, resulting in different sizes of the two matching gaps between the air guide plate and the casing air outlet, which will not only affect the overall aesthetics of the air conditioner indoor unit, but also affect the normal operation of the air guide plate.

[0004] A limiting structure is usually provided in some wall-mounted air-conditioning indoor units to limit the connection position between the air guide plate and the casing to prevent the air guide plate from being offset along the length direction of the casing. However, in the prior art, the positioning accuracy of the air guide plate by the limiting structure is poor. In addition, in some wall-mounted air-conditioning indoor units, the length dimension of the air guide plate is relatively large, and the length dimension of the air guide plate is also relatively large, which causes the air guide plate to easily shake relative to the casing when rotating, which not only affects the air outlet stability, but also increases the offset of the air guide plate along the length direction of the casing.

[0005] In view of this, this application is filed. Utility Model Content

[0058] In order to make the purpose and implementation method of the present application clearer, the exemplary implementation method of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0059] It should be noted that the brief description of terms in this application is only for the convenience of understanding the embodiments described below, and is not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their common and usual meanings.

[0060] The terms "first", "second", "third", etc. in the specification and claims of this application and the above drawings are used to distinguish similar or similar objects or entities, and do not necessarily mean to limit a specific order or sequence, unless otherwise noted. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances.

[0061] The terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to all the components expressly listed but may include other components not expressly listed or inherent to such product or device.

[0062] The air conditioner indoor unit provided in the embodiments of the present application may have various implementation forms.

[0063] like Figure 1-Figure 20 As shown, a wall-mounted air-conditioning indoor unit provided in the present application comprises at least a casing 100, a heat exchanger 300 and a heat exchange fan.

[0064] like Figure 1 , Figure 3 , Figure 5 As shown, the casing 100 is used to form the overall appearance of the air conditioner indoor unit. The casing 100 has a top and a bottom. The top of the casing 100 and the bottom of the casing 100 are opposite ends, and the height direction of the casing 100 is from the top of the casing 100 to the bottom of the casing 100.

[0065] The left side of the housing 100 and the right side of the housing 100 are opposite sides, and the length direction of the housing 100 is from the left side of the housing 100 to the right side of the housing 100.

[0066] The front side of the housing 100 and the rear side of the housing 100 are two opposite sides, and the direction from the front side of the housing 100 to the rear side of the housing 100 is the thickness direction of the housing 100 .

[0067] In practical applications, the housing 100 is usually disposed on the top of a room or in an upper space of a room, wherein the rear side of the housing 100 is disposed toward a wall, and the front side of the housing 100 is disposed toward a user.

[0068] A heat exchange channel is defined inside the casing 100, and the heat exchanger 300 is disposed in the heat exchange channel. Heat is exchanged in the indoor air in the heat exchange channel.

[0069] The casing 100 includes a casing air inlet 101 , which is communicated with the heat exchange channel, and the indoor air enters the heat exchange channel through the casing air inlet 101 .

[0070] The housing 100 includes a housing air outlet 102 , which is connected to the heat exchange channel. The air after heat exchange in the heat exchange channel is output to the room through the housing air outlet 102 .

[0071] The casing air inlet 101 is located at the top of the casing 100 , and the casing air inlet 101 extends along the length direction of the casing 100 .

[0072] The casing air outlet 102 is opened at the front side of the casing 100 and is arranged close to the bottom of the casing 100 , that is, the casing air outlet 102 is located at the front lower side of the casing 100 ; the casing air outlet 102 extends along the length direction of the casing 100 .

[0073] like Figure 5 and Figure 7 As shown, the housing 100 includes a cover 110 , and the cover 110 defines a cover cavity with an opening toward the rear side of the housing 100 .

[0074] like Fig.10 As shown, the housing 100 includes a base 120 , which is disposed in the cavity of the outer cover. The base 120 and the outer cover 110 together define a heat exchange channel, and the heat exchanger 300 and the heat exchange fan are installed on the base 120 .

[0075] The outer cover 110 has an outer cover opening 113 at the bottom of the front side, and the base 120 has a base opening 121 at the bottom of the front side. The base opening 121 is corresponding to the outer cover opening 113 to define the housing air outlet 102 together.

[0076] The casing air inlet 101 is opened at the top of the outer cover 110 .

[0077] The outer cover 110 is a frame structure, which can facilitate the contact between the heat exchanger 300 and the air inside the casing 100 on the one hand, and can reduce the weight of the outer cover 110 on the other hand.

[0078] An air inlet grille is provided at the air inlet 101 of the casing to prevent dust or debris from entering the interior of the casing 100 through the air inlet 101 of the casing.

[0079] In some embodiments, the air inlet grille and the outer cover 110 are integrally formed by injection molding. To prevent the appearance of the outer cover 110 from shrinking during injection molding, a process anti-shrinkage groove is usually provided at the air inlet grille. However, the process anti-shrinkage groove will affect the structural strength of the air inlet grille. If the process anti-shrinkage groove is provided in an area of ​​the outer cover 110 that is subjected to greater force, the outer cover 110 may cause cracking.

[0080] like Figure 2 As shown, in this embodiment, a first reinforcing rib 111 is provided on the outer cover 110 . The first reinforcing rib 111 is provided at the air inlet 101 of the casing to increase the strength of the outer cover 110 . The first reinforcing rib 111 extends in a direction intersecting with the length direction of the casing 100 .

[0081] It should be noted that the first reinforcing rib 111 is disposed in a region where the outer cover 110 and the base 120 are subjected to greater force.

[0082] like Figure 1 and Figure 3 As shown, an air guide plate 200 is disposed at the air outlet 102 of the casing. The air guide plate 200 is connected to the casing 100 in an openable and closable manner to open or close the air outlet 102 of the casing.

[0083] The air guide plate 200 rotates around its rotation axis to open or close the housing air outlet 102 .

[0084] The rotation axis of the air guide plate 200 is arranged along the length direction of the air outlet 102 of the casing.

[0085] It should be noted that, in some embodiments, the side of the air guide plate 200 close to the rotation axis of the air guide plate 200 is the root of the air guide plate 200 .

[0086] like Fig.10 As shown, the air guide plate 200 is connected to a driving motor 210 , and the driving motor 210 is used to drive the air guide plate 200 to rotate.

[0087] The driving motor 210 is disposed on one side of the air guide plate 200 close to the rotation axis of the air guide plate 200 to drive the air guide plate 200 to rotate around the rotation axis of the air guide plate 200 .

[0088] The number of driving motors 210 is usually two. The two driving motors 210 are mounted on the housing 100 and are correspondingly arranged at two ends of the air guide plate 200 along the length direction of the housing 100 . The two driving motors 210 operate synchronously.

[0089] It should be noted that the two driving motors 210 can not only provide a larger rotational driving force to the air guide plate 200 , but the motor shafts of the two driving motors 210 can also support the rotation of the air guide plate 200 , thereby increasing the stability of the rotation of the air guide plate 200 .

[0090] When the conditioned air is output from the casing air outlet 102 to the room, it will contact the windward side of the air guide plate 200. The heat or cold in the conditioned air will inevitably be transferred to the air guide plate 200, which may easily cause the air guide plate 200 to deform due to heat or cold.

[0091] like Fig.15 As shown, in this embodiment, the wind guide plate 200 is designed as a split structure including a first wind plate 220 and a second wind plate 230, and the second wind plate 230 is utilized to contact the air-conditioning wind so that the second wind plate 230 bears the heat or cold of the air-conditioning wind. When the second wind plate 230 is deformed, only the second wind plate 230 needs to be repaired and replaced, thereby reducing the repair and replacement cost of the wind guide plate 200.

[0092] Specifically, the first wind plate 220 is located on the leeward side of the wind guide plate 200 , and the second wind plate 230 is located on the windward side of the wind guide plate 200 .

[0093] The first wind plate 220 and the second wind plate 230 are detachably connected to each other, so as to facilitate maintenance and replacement of the second wind plate 230 .

[0094] The side of the second wind plate 230 facing away from the first wind plate 220 is the windward side of the second wind plate 230. The shape of the windward side of the second wind plate 230 is adapted to the flow path of the air-conditioning wind output from the casing air outlet 102 to the indoor room. The second wind plate 230 is streamlined to better guide the flow of the air-conditioning wind.

[0095] like Fig.15 and Fig.16 As shown, the first air plate 220 is provided with a first clamping portion 223 , and the first clamping portion 223 is provided on one side of the first air plate 220 extending along the length direction of the housing 100 .

[0096] The second air plate 230 is provided with a second clamping portion 232 . The second clamping portion 232 is provided at one side of the second air plate 230 extending along the length direction of the housing 100 .

[0097] The first clamping portion 223 and the second clamping portion 232 are correspondingly disposed so that the first air plate 220 and the second air plate 230 are connected to each other.

[0098] The first air plate 220 is further provided with a first contact portion 221 . The first contact portion 221 is provided at one side of the first air plate 220 extending along the length direction of the housing 100 .

[0099] The second air plate 230 is further provided with a second contact portion 231 . The second contact portion 231 is respectively provided on one side of the second air plate 230 extending along the length direction of the housing 100 .

[0100] The first contact portion 221 and the second contact portion 231 are disposed correspondingly so that the first air plate 220 and the second air plate 230 are connected to each other.

[0101] It should be noted that the first clamping portion 223 and the first contact portion 221 are correspondingly disposed on two sides of the first air plate 220 extending along the length direction of the housing 100 .

[0102] The second clamping portion 232 and the second contact portion 231 are respectively disposed on two sides of the second air plate 230 extending along the length direction of the housing 100 .

[0103] When the first air plate 220 and the second air plate 230 are connected to each other, the first contact portion 221 and the second contact portion 231 are firstly brought into contact with each other, and then the first clamping portion 223 is disposed in the second clamping portion 232 .

[0104] In some other embodiments, the portion where the first contact portion 221 and the second contact portion 231 abut against each other is an inclined plane.

[0105] In some embodiments, the first clamping portion 223 is located on a side of the first air plate 220 close to the rotation axis of the air guide plate 200 .

[0106] In some embodiments, the first clamping portion 223 is located on a side of the first wind plate 220 facing the second wind plate 230 .

[0107] In some embodiments, the first contact portion 221 is located on a side of the first air plate 220 away from the rotation axis of the air guide plate 200 .

[0108] In some embodiments, the first contact portion 221 is located on a side of the first wind plate 220 facing the second wind plate 230 .

[0109] In some embodiments, the second clamping portion 232 is located on a side of the second air plate 230 close to the rotation axis of the air guide plate 200 .

[0110] In some embodiments, the second clamping portion 232 is located on a side of the second wind plate 230 facing the first wind plate 220 .

[0111] In some embodiments, the second contact portion 231 is located on a side of the second air plate 230 away from the rotation axis of the air guide plate 200 .

[0112] In some embodiments, the second contact portion 231 is located on a side of the second wind plate 230 facing the first wind plate 220 .

[0113] In some embodiments, a flange is provided on one side of the second air plate 230 close to the rotation axis of the air guide plate 200 , and the second clamping portion 232 is opened on the flange.

[0114] In some other embodiments, the first wind plate 220 is further provided with a blocking portion 222 , and the blocking portion 222 cooperates with the flange to locate the installation position of the second wind plate 230 and the first wind plate 220 .

[0115] It should be noted that there are multiple blocking parts 222 , and the multiple blocking parts 222 are distributed along the length direction of the housing 100 .

[0116] The first clamping portion 223 and the second clamping portion 232 are also provided in plurality, and the plurality of first clamping portions 223 and the plurality of second clamping portions 232 are provided in one-to-one correspondence and are respectively distributed along the length direction of the housing 100 .

[0117] By providing a first clamping portion 223 and a first contact portion 221 on the first wind plate 220, and providing a second clamping portion 232 and a second contact portion 231 on the second wind plate 230, and utilizing the first clamping portion 223 and the second clamping portion 232 to cooperate with each other, and the first contact portion 221 and the second contact portion 231 to cooperate with each other, not only can the installation and disassembly of the first wind plate 220 and the second wind plate 230 be facilitated, but also the first wind plate 220 and the second wind plate 230 are firmly connected, which facilitates the manufacture of the first wind plate 220 and the second wind plate 230, and by providing a blocking portion 222 on the first wind plate 220, the blocking portion 222 and the flange of the second wind plate 230 are abutted against each other to locate the connection position of the first wind plate 220 and the second wind plate 230.

[0118] Since the first wind plate 220 and the second wind plate 230 are detachably connected and located on the leeward side of the second wind plate 230 , the heat or cold in the air-conditioning wind is easily transferred to the first wind plate 220 through the second wind plate 230 , causing the first wind plate 220 to deform.

[0119] To solve this problem, in this embodiment, a heat-insulating material is provided between the first wind plate 220 and the second wind plate 230 to prevent the temperature of the second wind plate 230 from being transferred to the first wind plate 220 as much as possible, thereby avoiding deformation of the first wind plate 220.

[0120] Specifically, Fig.15 As shown, the first wind plate 220 and the second wind plate 230 define a storage cavity 201, which is located inside the wind guide plate 200. Insulating material is placed in the storage cavity 201 to prevent the temperature of the second wind plate 230 from being transferred to the first wind plate 220, thereby avoiding deformation of the first wind plate 220.

[0121] It should be noted that the thermal insulation material is usually thermal insulation sponge.

[0122] like Fig.10 As shown, the heat exchanger 300 is installed in the housing 100 and is located in the heat exchange channel. After the air in the heat exchange channel contacts the heat exchanger 300, it is heat-exchanged by the heat exchanger 300 to form air-conditioned air to meet the user's cooling or heating needs.

[0123] It should be noted that the heat exchanger 300 is disposed close to the housing air inlet 101. It should also be noted that the air-conditioned air can be cold air, hot air, or even normal temperature air.

[0124] The heat exchange fan is installed in the housing 100 and is located in the heat exchange channel. The heat exchange fan is located below the heat exchanger 300 , and the axial direction of the heat exchange fan extends along the length direction of the housing 100 .

[0125] The heat exchange fan is operated to introduce indoor air into the heat exchange channel from the housing air inlet 101, and after heat exchange in the heat exchanger 300 to form conditioned air, the conditioned air flows into the room from the housing air outlet 102. It should be noted that the heat exchange fan is a cross-flow fan.

[0126] The air conditioner indoor unit also includes a display component, which includes a display box 400 and a display panel. The display panel is installed on the display box 400, and the display box 400 is arranged close to the front side of the casing 100. The display panel is used to display information related to the operation of the air conditioner indoor unit; the display panel is used to control relevant information during the operation of the air conditioner indoor unit, such as the operating mode of the air conditioner indoor unit and related information such as the set temperature and wind speed.

[0127] In some embodiments, the display panel is also used to display different colors to increase the aesthetics of the air conditioner indoor unit.

[0128] It should be noted that the display content and the display principle of the display panel belong to the common knowledge in the art and will not be described in detail here.

[0129] Since the outer cover 110 is a frame structure, during a drop test or transportation of the air conditioner indoor unit, the display box 400 can easily pass through the outer cover 110 and contact the side of the heat exchanger 300 facing the front side of the housing 100 , causing damage to the heat exchanger 300 .

[0130] like Figure 7 and Fig. 9 As shown, in this embodiment, a support portion 112 is provided on the outer cover 110. By disposing the support portion 112 between the display box 400 and the heat exchanger 300, the support portion 112 is used to prevent the display box 400 from directly contacting the heat exchanger 300, so as to prevent the display box 400 from causing damage to the heat exchanger 300 during a drop test or transportation of the air conditioner indoor unit.

[0131] Specifically, the support portion 112 is disposed on the outer cover 110 and is located on a side of the outer cover 110 facing the front side of the casing 100. The support portion 112 is located between the display box 400 and the heat exchanger 300. When the display box 400 is subjected to an external force and approaches the heat exchanger 300, the display box 400 first contacts the support portion 112, and the support portion 112 generates a reverse force on the display box 400 to prevent the display box 400 from continuing to approach the heat exchanger 300.

[0132] When the reaction force of the support portion 112 on the display box 400 is smaller than the external force applied to the display box 400, the display box 400 continues to move toward the heat exchanger 300, and the display box 400 makes the support portion 112 contact with the heat exchanger 300. At this time, the external force applied to the display box 400 is partially offset by the reaction force provided by the support portion 112. Therefore, the damage to the heat exchanger 300 is relatively small. This is common knowledge in the art and will not be elaborated herein.

[0133] It should be noted that the heat exchanger 300 is usually a fin heat exchanger 300 . When the heat exchanger 300 collides or interacts with other components, the fins are likely to fall over, thereby reducing the heat exchange efficiency of the heat exchanger 300 .

[0134] like Figure 3 , Figure 4 and Figure 6 As shown, the air conditioner indoor unit further includes an air guide blade 500 , and the air guide blade 500 is disposed at the air outlet 102 of the casing.

[0135] A plurality of air guide blades 500 are provided, and the plurality of air guide blades 500 are distributed along the length direction of the casing 100 to guide the air conditioning wind to be output from the casing air outlet 102 to the indoor direction and to increase the air outlet range of the air conditioning wind.

[0136] At present, some air-conditioning indoor units are relatively large in length, and the length of the casing air outlet 102 along the length direction of the casing 100 and the length of the air guide plate 200 are also relatively large accordingly. Only providing support for the two ends of the air guide plate 200 along the length direction of the casing 100 can no longer meet the requirement of smooth rotation of the air guide plate 200.

[0137] Since the middle portion of the air guide plate 200 along the length direction of the housing 100 lacks support, the air guide plate 200 is prone to shaking during rotation, which not only affects the air outlet stability, but also generates noise due to the shaking, thereby reducing the user experience.

[0138] like Figure 3-Figure 6 As shown, in this embodiment, a support member 600 is provided at the air outlet 102 of the casing, so that the air guide plate 200 is rotatably connected to the support member 600 , so that the support member 600 provides support for the rotation of the air guide plate 200 .

[0139] In some embodiments, the support member 600 is disposed at the middle portion of the housing air outlet 102 along the length direction of the housing 100 .

[0140] When the support member 600 is disposed at the middle portion of the housing air outlet 102 along the length direction of the housing 100 , the support force of the support member 600 on the air guide plate 200 can be applied to the air guide plate 200 more evenly.

[0141] like Figure 8 and Fig.11 As shown, the support member 600 is disposed at the base opening 121 and is disposed along a direction intersecting with the extending direction of the housing air outlet 102 .

[0142] The support member 600 is connected to the outer edges of both sides of the base opening 121 extending along the length direction of the housing 100 . Therefore, the support member 600 can also increase the strength of the base 120 .

[0143] It should be noted that since the support member 600 is disposed at the air outlet 102 of the housing, the size of the support member 600 along the length direction of the housing 100 should not be too large, otherwise it will affect the air outlet of the air conditioning air. However, if the size is too small, the strength of the support member 600 will be reduced.

[0144] In some embodiments, a second reinforcing rib 604 is disposed on one side of the support member 600 along the length direction of the housing 100 to increase the strength of the support member 600 .

[0145] The support member 600 is provided with a second connection part 601, the second connection part 601 is connected to a rotating member 700, the rotating member 700 is installed on the second wind plate 230, and the second connection part 601 is rotatably connected to the second wind plate 230 through the rotating member 700, so that the support member 600 can support the wind guide plate 200 to rotate.

[0146] like Fig.14 As shown, the second wind plate 230 is provided with a first connection portion 203 , and the rotating member 700 is connected to the first connection portion 203 , so that the rotating member 700 is connected to the second wind plate 230 .

[0147] There are two first connection parts 203 , which are distributed along the length direction of the housing 100 and define a gap between the two first connection parts 203 along the length direction of the housing 100 .

[0148] The second connection portion 601 is disposed in the gap, so that the first connection portion 203 can limit the connection position between the support member 600 and the rotating member 700 along the length direction of the housing 100 .

[0149] When the second connection portion 601 is disposed in the gap, the two first connection portions 203 are correspondingly disposed on both sides of the support member 600 along the length direction of the housing 100 .

[0150] The first connection portion 203 is located on the windward side of the wind deflector 200 and is disposed close to the rotation axis of the wind deflector 200 .

[0151] like Fig.19 and Fig. 20 As shown, the rotating member 700 includes a rotating portion 710 , and the rotating portion 710 is rotatably connected to the second connecting portion 601 and the first connecting portion 203 , so that the second wind plate 230 is rotatably connected to the second connecting portion 601 through the rotating member 700 .

[0152] In some embodiments, Fig.14 and Fig.18 As shown, the first connection portion 203 is provided with a first connection hole, and the rotating portion 710 is disposed in the first connection hole, so that the rotating member 700 is rotatably connected to the first connection portion 203 .

[0153] like Figure 6, Figure 8 and Fig.11 As shown, the second connection portion 601 is provided with a second connection hole, and the rotating portion 710 is provided in the second connection hole, so that the rotating member 700 is rotatably connected to the second connection portion 601 .

[0154] In some embodiments, the opening directions of the first connection hole and the second connection hole are respectively arranged along the length direction of the housing 100 , and the axis of the rotating portion 710 is arranged along the length direction of the housing 100 .

[0155] The rotating member 700 includes a rotating body 720 , and the rotating body 720 is connected to the second wind plate 230 to increase the firmness of the connection between the rotating member 700 and the second wind plate 230 .

[0156] It should be noted that the rotating portion 710 is located at one end of the rotating body 720 along the length direction of the housing 100 .

[0157] like Fig.18 As shown, the second wind plate 230 is provided with a mounting portion 204 , and the mounting portion 204 is used to fix the rotating body 720 .

[0158] In some embodiments, the first connection portion 203 is disposed close to the mounting portion 204 on one side along the length direction of the housing 100 .

[0159] like Fig. 20 As shown, the rotating body 720 is provided with a fixing portion 730 , and the fixing portion 730 is located on a side of the rotating body 720 facing the second wind plate 230 .

[0160] The fixing portion 730 is disposed corresponding to the mounting portion 204 . The fixing portion 730 is disposed on the mounting portion 204 so that the rotating body 720 is fixedly connected to the second wind plate 230 .

[0161] In some embodiments, the mounting portion 204 is provided with a slot, and the fixing portion 730 is snapped into the slot to fix the rotating member 700 to the second wind plate 230, which not only increases the firmness of the rotating member 700 installed on the second wind plate 230, but also facilitates the removal of the rotating member 700 from the second wind plate 230.

[0162] When the rotating member 700 needs to be disassembled, the fixing portion 730 is separated from the slot, so that the rotating member 700 can be disassembled from the second air plate 230 .

[0163] In some embodiments, the mounting portion 204 is disposed at the middle portion of the second wind plate 230 along the length direction of the casing 100, and the mounting portion 204 is recessed on the windward side of the second wind plate 230, so that when the rotating body 720 is installed on the mounting portion 204, the side surface of the rotating body 720 facing the support member 600 can be roughly aligned with the windward side of the second wind plate 230, which can not only maintain the aesthetics of the second wind plate 230, but also prevent the rotating body 720 from interfering with the rotation of the second wind plate 230.

[0164] In some embodiments, the first connection portion 203 is disposed on a windward side of the protruding second wind plate 230 .

[0165] In actual production, the mounting portion 204, the first connecting portion 203 and the second wind plate 230 are integrally injection molded. Since the first connecting portion 203 is provided with a first connecting hole, during injection molding, if the second connecting hole is designed to be a full circle, in order to facilitate the smooth separation of the mold used to form the first connecting hole, the second wind plate 230 usually needs to be designed with an avoidance portion to facilitate demolding. The avoidance portion is provided on the windward side of the second wind plate 230, which will affect the aesthetics of the second wind plate 230.

[0166] In order to facilitate demoulding during injection molding, in this embodiment, the first connecting portion 203 is designed to include a first transition side wall 2031 and a second transition side wall 2032 , and the first transition side wall 2031 and the second transition side wall 2032 are used to jointly define a second connecting hole.

[0167] The first adapter side wall 2031 and the second adapter side wall 2032 are distributed along the length direction of the housing 100 . The second adapter side wall 2032 is located on a side of the first adapter side wall 2031 away from the mounting portion 204 along the length direction of the housing 100 .

[0168] The first adapter side wall 2031 is protruded and disposed on the windward side of the second wind plate 230 , and the second adapter side wall 2032 is recessed and disposed on the windward side of the second wind plate 230 .

[0169] The rotating portion 710 contacts the first adapter side wall 2031 and the second adapter side wall 2032 at the same time, so that the rotating portion 710 and the first connecting portion 203 are rotatably connected to each other.

[0170] When the rotating portion 710 contacts the first adapter side wall 2031 and the second adapter side wall 2032 at the same time, the first adapter side wall 2031 and the second adapter side wall 2032 respectively constrain both sides of the normal direction of the rotating portion 710 so that the rotating portion 710 can be reliably rotatably connected with the first connecting portion 203 .

[0171] It should be noted that since the first adapter side wall 2031 is protruding from the windward side of the second wind plate 230, in order to facilitate the manufacture of the first adapter side wall 2031, the second wind plate 230 is provided with a through hole 205 below the first adapter side wall 2031, so that the mold used to produce the first adapter side wall 2031 can be demoulded through the through hole 205, and the second adapter side wall 2032 is recessed in the windward side of the second wind plate 230, and the mold used to produce the second adapter side wall 2032 can be demoulded by moving away from the second wind plate 230 in a direction perpendicular to the windward side of the second wind plate 230.

[0172] It should be noted that since there are two first connection parts 203, during actual production, the mold for forming the first connection hole can move in the direction of the first connection part 203 away from the mounting part 204, and can be demolded from the gap formed by the two first connection parts 203. Therefore, the first connection part 203 close to the mounting part 204 can be designed as a full circle without being designed as a split type. This is common knowledge in the field and will not be elaborated herein.

[0173] In some embodiments, the motor shaft of the driving motor 210 is also connected to a rotating member 700 , and the motor shaft of the driving motor 210 is connected to the air guide plate 200 for rotation via the rotating member 700 .

[0174] When the motor shaft of the driving motor 210 is connected to the second wind plate 230 through the rotating member 700, in order to facilitate the connection between the motor shaft and the rotating member 700, the rotating part 710 is provided with a connecting cavity, and the motor shaft of the driving motor 210 is arranged in the connecting cavity so that the motor shaft of the driving motor 210 is connected to the rotating member 700.

[0175] The connecting cavity is formed in the rotating portion 710 , and the opening of the connecting cavity is disposed at an end of the rotating portion 710 away from the rotating body 720 .

[0176] In some embodiments, Fig.15 As shown, the second wind plate 230 is provided with a third connecting part 206 at both ends along the length direction of the casing 100, and the rotating member 700 connected to the motor shaft is connected to the third connecting part 206, so that the third connecting part 206 imposes constraints on the rotating part 710, thereby increasing the firmness of the connection between the rotating member 700 and the second wind plate 230.

[0177] In some embodiments, Fig.11 As shown, the support member 600 is disposed protruding from the surface of the base 120 . When the outer cover 110 is connected to the base 120 , the support member 600 may interfere with the connection between the base 120 and the outer cover 110 .

[0178] A protrusion 602 is defined at the lower end of the support member 600 . The protrusion 602 is located at a side of the support member 600 facing away from the interior of the housing 100 .

[0179] The outer cover 110 is provided with a clearance portion 114 , and the clearance portion 114 is arranged corresponding to the protrusion 602 to prevent the protrusion 602 from interfering with the connection between the base 120 and the outer cover 110 .

[0180] When the outer cover 110 and the base 120 are connected, the protrusion 602 is disposed in the clearance portion 114 . Therefore, when the outer cover 110 and the base 120 are connected, the connection position of the outer cover 110 and the base 120 can be positioned by disposing the protrusion 602 in the clearance portion 114 .

[0181] In some embodiments, the clearance portion 114 is a notch formed in the outer cover 110 , and the protrusion 602 is disposed in the notch to locate the connection position between the base 120 and the outer cover 110 .

[0182] In some embodiments, the raised portion 602 extends to the outer edge of one side of the base 120 extending along the length direction of the housing 100. Therefore, the raised portion 602 also increases the connection area between the support member 600 and the base 120, thereby increasing the connection strength between the support member 600 and the base 120.

[0183] A support member 600 is provided at the base opening 121 to prevent the base opening 121 from being deformed, thereby increasing the strength of the base 120; and the support member 600 is used to support the rotation of the air guide plate 200 to increase the stability of the operation of the air guide plate 200 and reduce the noise generated by the rotation of the air guide plate 200; and the strength of the base 120 can be increased without affecting the air outlet effect of the air conditioner, thereby improving the stability of the rotation of the air guide plate 200.

[0184] The two ends of the air guide plate 200 along the length direction of the casing 100 are arranged in one-to-one correspondence with the two side edges of the casing air outlet 102 in the length direction, and there is a gap between the ends of the air guide plate 200 along the length direction of the casing 100 and the corresponding edges of the casing air outlet 102 to ensure that the air guide plate 200 can rotate reliably. The two gaps between the two ends of the air guide plate 200 and the two side edges of the casing air outlet 102 are generally substantially the same in size along the length direction of the casing 100 to ensure the aesthetics of the air conditioner indoor unit.

[0185] Since the air guide plate 200 will inevitably deviate along the length direction of the casing 100 during rotation, it will not only affect the operation of the air guide plate 200, but also when the air guide plate 200 closes the casing air outlet 102, the sizes of the two gaps along the length direction of the casing 100 are different, affecting the aesthetics of the air conditioner indoor unit.

[0186] In this embodiment, Fig.12 , Fig.14 and Fig.18 As shown, a constraint portion 202 is provided at the root of the air guide plate 200, and the constraint portion 202 is provided corresponding to the support member 600. The support member 600 is used to adjust the connection position of the air guide plate 200 and the support member 600 along the length direction of the casing 100, thereby adjusting the setting position of the air guide plate 200 along the length direction of the casing 100 to prevent the air guide plate 200 from deviating along the length direction of the casing 100.

[0187] When the air guide plate 200 rotates until the restraining portion 202 contacts the support member 600 , the support member 600 adjusts the connection position of the air guide plate 200 and the support member 600 along the length direction of the housing 100 through the restraining portion 202 .

[0188] In some embodiments, when the air guide plate 200 rotates to open the housing air outlet 102 at a maximum angle, the restraining portion 202 and the bottom of the supporting member 600 are in contact with each other.

[0189] The constraint portion 202 is located on a side of the air guide plate 200 close to the rotation axis of the air guide plate 200 , so that the constraint portion 202 can contact the support member 600 when the air guide plate 200 rotates.

[0190] The restraining portion 202 is disposed between the two first connecting portions 203 along the length direction of the housing 100 .

[0191] In some embodiments, the support member 600 is provided with a limiting portion 603, which is located below the second connecting portion 601. The limiting portion 603 and the constraint portion 202 are correspondingly arranged and cooperate with each other. The constraint portion 202 is used to constrain the position of the limiting portion 603 to adjust the connection position of the air guide plate 200 and the support member 600 along the length direction of the casing 100.

[0192] The constraint portion 202 is provided with a first mating surface, which is located on one of the inner walls of the constraint portion 202 set along the length direction of the casing 100; the limiting portion 603 is provided with a second mating surface, which is located on one of the side walls of the limiting portion 603 set along the length direction of the casing 100, and the second mating surface is set corresponding to the first mating surface.

[0193] There are two first mating surfaces, which are correspondingly arranged on the inner walls of the constraint portion 202 along the length direction of the housing 100; the two first mating surfaces jointly define a recess, and the limiting portion 603 is arranged in the recess and matched with the recess.

[0194] There are also two second mating surfaces, which are correspondingly arranged on the two side walls of the limiting portion 603 along the length direction of the housing 100 , and the two first mating surfaces are arranged in one-to-one correspondence with the two second mating surfaces.

[0195] It should be noted that there is usually a certain gap between the first mating surface and the second mating surface to ensure that the air guide plate 200 can rotate reliably. However, if there is a gap between the first mating surface and the second mating surface, the positioning accuracy of the air guide plate 200 is easily reduced.

[0196] like Fig.12 As shown, in this embodiment, the first mating surface and the second mating surface are set as inclined surfaces, so that when the air guide plate 200 moves along the length direction of the housing 100, the first mating surface and the second mating surface can contact each other without affecting the rotation of the air guide plate 200.

[0197] The distance between the two first mating surfaces along the length direction of the housing 100 increases from the end where the constraint portion 202 is connected to the air guide plate 200 toward the end where the constraint portion 202 is away from the air guide plate 200 .

[0198] The distance between the two second mating surfaces decreases from the top of the support member 600 toward the bottom of the support member 600 .

[0199] The two first matching surfaces jointly define the recess to form a V-shaped structure.

[0200] The two second matching surfaces also limit the limiting portion 603 to form a V-shaped structure.

[0201] The minimum dimension between the two first mating surfaces along the length direction of the casing 100 is greater than the minimum dimension between the two second mating surfaces along the length direction of the casing 100, and the minimum dimension between the two first mating surfaces along the length direction of the casing 100 is smaller than the maximum dimension between the two second mating surfaces along the length direction of the casing 100.

[0202] Since the bottom of the support member 600 is arranged in the gap formed by the two first connecting parts 203, the maximum distance between the two first mating surfaces along the length direction of the casing 100 is less than or equal to the spacing between the two first connecting parts 203 along the length direction of the casing 100, so that the first mating surface can contact the support member 600.

[0203] The maximum distance between the two second mating surfaces along the length direction of the housing 100 is less than or equal to the spacing between the two first connecting portions 203 along the length direction of the housing 100 , so that the support member 600 can be disposed in the gap formed by the two first connecting portions 203 .

[0204] The working principle of the above-mentioned air-conditioning indoor unit is as follows: when the air guide plate 200 is to close the air outlet 102 of the casing, the driving motor 210 drives the air guide plate 200 to rotate until the constraint part 202 and the support member 600 contact each other, and the two first mating surfaces of the constraint part 202 interact with the two second mating surfaces of the limiting part 603 to adjust the position of the air guide plate 200 along the length direction of the casing 100, so that when the air guide plate 200 closes the air outlet 102 of the casing, the gaps between the two ends of the air guide plate 200 relatively set along the length direction of the casing 100 and the two side edges of the casing air outlet 102 relatively set along the length direction of the casing 100 can be roughly symmetrically arranged, thereby ensuring the aesthetics of the air-conditioning indoor unit.

[0205] The above-mentioned air-conditioning indoor unit sets a constraint part 202 on the air guide plate 200 and sets a limit part 603 on the support member 600, and uses the constraint part 202 and the limit part 603 to cooperate with each other to adjust the connection position of the air guide plate 200 and the support member 600 along the length direction of the casing 100, thereby preventing the air guide plate 200 from shifting along the length direction of the casing 100, and ensuring the aesthetics of the air-conditioning indoor unit when the air guide plate 200 closes the air outlet 102 of the casing.

[0206] The support member 600 in the above-mentioned air-conditioning indoor unit can not only support the rotation of the air guide plate 200 and increase the stability of the rotation of the air guide plate 200, but also adjust the setting position of the air guide plate 200 along the length direction of the casing 100, thereby ensuring the reliability of the air guide plate 200 and the aesthetics of the air-conditioning indoor unit when the casing air outlet 102 is closed.

[0207] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
