[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0032] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0033] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0034] The present invention proposes an air-conditioning indoor unit, which can be a wall-mounted air-conditioning indoor unit, a floor-standing air-conditioning indoor unit or a vertically mounted air-conditioning indoor unit, etc. The present invention is described using a floor-standing air-conditioning indoor unit as an example, but the present invention is not limited to this.

[0035] In the embodiment of the present invention, Figures 1 to 6 As shown, the air conditioner indoor unit includes: a shell, including a front shell 11 and a rear shell 12 spliced ​​together, the front shell 11 is provided with an air outlet 111; a duct component 20, arranged in the shell, the duct component 20 includes an air duct shell 21 and a fan 22 arranged in the air duct shell 21; an air outlet component, arranged between the front shell 11 and the air duct shell 21, the air outlet component includes a bracket 31 and a damper 32, the bracket 31 is connected to the air duct shell 21 and is provided with an air outlet 311, the air outlet 311 connects the air outlet 111 with the air outlet end of the air duct shell 21, the damper 32 can be movably mounted on the bracket 31 to open or close the air outlet 111, the back of the front shell 11 has an exposed area 113 facing the air duct component 20, and the exposed area 113 is located between the side of the bracket 31 and the rear side of the front shell 11.

[0036] In this embodiment, the housing forms the overall appearance of the air conditioner indoor unit, and the rear housing 12 is provided with an air inlet. An air duct is formed within the air duct housing 21, and a fan 22 is provided to drive air through the air duct housing 21. A heat exchanger is also provided within the housing, and the fan 22 can drive external air into the air duct from the air inlet, and blow it out from the air outlet 111 after heat exchange in the heat exchanger. The air outlet component is mounted on the inner side of the air outlet 111, wherein a bracket 31 is provided for mounting the air outlet structure including the damper 32 to reduce the burden on the front housing 11 and prevent damage to the front housing 11. The bracket 31 can be in the shape of a frame extending along the circumference of the air outlet 111, enclosing an air outlet 311, which is in communication with the air outlet 111. The damper 32 can be located on the side of the bracket 31 adjacent to the front shell 11, or on the side of the bracket 31 away from the front shell 11. There is no limitation here, as long as the damper 32 can open or close the air outlet 111; when the damper 32 opens the air outlet 111, the damper 32 is located on the back side of the front shell 11 to play a hiding role.

[0037] The back area of ​​the front shell 11 corresponding to the bracket 31 and the rear side of the front shell 11 is exposed toward the air duct component 20, indicating that the bracket 31 does not completely cover the back of the front shell 11, that is, there is a certain distance between the bracket 31 and the rear side of the front shell 11. The rear side of the front shell 11 is the vertical side of the front shell 11. The distance between the bracket 31 and the rear side of the front shell 11 can be understood as the distance between the two vertical frame edges of the bracket 31 and the two vertical sides of the front shell 11. The two vertical sides of the bracket 31 are spaced apart from the two vertical sides of the front shell 11, indicating that the width of the vertical sides of the bracket 31 itself is relatively small, that is, the lateral dimension of the bracket 31 is relatively small, thereby simplifying the structure of the bracket 31, that is, simplifying the internal structure of the air conditioner indoor unit; thereby, both the cost of the air outlet component and the difficulty of assembling the air outlet component can be reduced.

[0038] The bracket 31 is connected to the air duct shell 21. When assembling the air conditioner indoor unit, the air duct component 20 is first installed on the rear shell 12, and then the air outlet component is installed on the air duct component 20. Finally, the front shell 11 and the rear shell 12 are spliced. The front shell 11 can be connected to the bracket 31 or not. There is no restriction here. It is only necessary to ensure that the bracket 31 is connected to the air duct shell 21. In this way, the air duct shell 21 can support the air outlet component as a whole. In actual application, the distance between the long side of the bracket 31 and the long side of the front shell 11 is not less than 150mm and not more than 200mm, and can be optionally 180mm. This distance can be obtained by a slider that slides unimpeded between the long side of the bracket 31 and the long side of the front shell 11. The maximum lateral dimension of the slider is the distance between the bracket 31 and the rear side of the front shell 11. The distance between the bracket 31 and the rear side of the front shell 11 is set to 150 mm to 200 mm, which can minimize the size of the bracket 31 while ensuring the structural strength of the bracket 31.

[0039] The air conditioner indoor unit of the present invention installs the bracket 31 between the front shell 11 and the air duct component 20, and provides the front shell 11 with an exposed area exposed toward the air duct component 20, thereby simplifying the structure of the bracket 31 and reducing the volume of the bracket 31, thereby simplifying the structure of the air outlet component, thereby reducing the production cost and assembly difficulty of the air conditioner indoor unit.

[0040] like Figure 2As shown, the air outlet component also includes a connecting portion 33 connected to the bracket 31, and the connecting portion 33 has a through hole 331. The air duct component 20 also includes a fixing portion 23 connected to the air duct shell 21, and the fixing portion 23 has a fixing hole 231. The through hole 331 and the fixing hole 231 can be connected by fasteners. In this embodiment, the connecting portion 33 extends horizontally and its two ends are respectively connected to the two vertical frame edges of the bracket 31. The fixing portion 23 extends horizontally and its two ends are respectively connected to the two vertical edges of the air outlet end of the air duct shell 21. The through hole 331 on the connecting portion 33 and the fixing hole 231 on the fixing portion 23 are connected by fasteners to achieve a fixed connection between the bracket 31 and the air duct shell 21. The number of connecting portions 33 can be multiple and spaced apart along the height direction of the bracket 31. The number and position of the fixing portions 23 correspond to the connecting portions 33 to improve the connection strength between the bracket 31 and the air duct shell 21.

[0041] like Figure 2 As shown, the bracket 31 is provided with a hook 312 on one side facing the air duct housing 21, and the air duct housing 21 is provided with a slot 211 adapted to the hook 312. In this embodiment, the hook portion of the hook 312 faces downward, and the hook 312 is hooked into the slot 211 to achieve pre-fixation of the bracket 31 and the air duct housing 21, and then fixedly connected by other means such as fasteners. The number of hooks 312 can be multiple and spaced along the height direction of the bracket 31. The number and position of the slots 211 correspond to the hooks 312 to improve the assembly strength of the bracket 31 and the air duct housing 21. Of course, the air duct housing 21 can also be provided with a convex rib, and the hook 312 can be hooked into the rib to further improve the assembly stability of the bracket 31 and the air duct housing 21.

[0042] like Figure 3 As shown, a sealing portion 313 is formed on the side of the bracket 31 facing the air duct component 20. The sealing portion 313 seals against the edge of the air outlet end of the air duct housing 21. In this embodiment, the sealing portion 313 can directly overlap the edge of the air outlet end of the air duct housing 21, or it can cover the edge of the air outlet end of the air duct housing 21 to improve sealing. The sealing portion 313 cooperates with the edge of the air outlet end of the air duct housing 21 to prevent air leakage during the flow from the air duct housing 21 to the air outlet 111, thereby improving air outlet efficiency.

[0043] like Figure 4As shown, the back side of the front shell 11 is provided with a protruding hook 112, and the bracket 31 is provided with a locking hole 314 adapted to the hook 112. In this embodiment, the front shell 11 is connected to the bracket 31 through the cooperation of the hook 112 and the locking hole 314. It should be noted that the front shell 11 is primarily fixed by being assembled and connected to the rear shell 12. The locking connection with the bracket 31 is mainly to prevent the front shell 11 from shaking, thereby making the internal structure of the air conditioner indoor unit more compact. The number of hooks 112 can be multiple and spaced along the height direction of the front shell 11. The number and position of the locking holes 314 correspond to the hooks 112 to further improve the assembly stability of the front shell 11 and the bracket 31.

[0044] like Figure 4 As shown, the air vent component further includes a protective plate 24 mounted on the bracket 31. The protective plate 24 is located in front of the damper 32, which opens the air vent 311. In this embodiment, the damper 32 has a first position that opens the air vent 311. When the damper 32 is in the first position, the protective plate 24 is located between the damper 32 and the front housing 11. During assembly of the air conditioner indoor unit, the air duct component 20 is first assembled with the air vent component and then transported and installed within the housing. The protective plate 24 protects the damper 32 during transport. A gap is created between the protective plate 24 and the damper 32 to prevent obstruction of the damper 32's movement. Furthermore, the protective plate 24 can also separate the damper 32 from the front housing 11 after assembly to prevent frictional resistance caused by the front housing 11 on the sliding movement of the damper 32. Specifically, the protective plate 24 has a reinforcing rib 241 protruding from the side facing the front housing 11. The reinforcing ribs 241 extend laterally to enhance the structural strength of the protective plate 24 and strengthen its protection of the damper 32. The reinforcing ribs 241 are protruding from the side of the protective plate 24 facing away from the damper 32 to prevent obstruction of the damper 32's movement. Multiple reinforcing ribs 241 can be provided, spaced longitudinally to further enhance the structural strength of the protective plate 24.

[0045] like Figure 5 and Figure 6As shown, the tuyere component further includes a drive assembly mounted on the end of the bracket 31. The drive assembly is connected to the damper 32 to drive the damper 32 to slide. In this embodiment, the drive assembly can be mounted on one end of the bracket 31 or on both ends of the bracket 31, without limitation. The drive assembly is used to drive the damper 32 to slide. Mounting the drive assembly on the bracket 31 allows the drive assembly to be part of the tuyere component. During assembly, the drive assembly is first mounted on the bracket 31, and then the tuyere component is mounted as a whole on the back side of the front housing 11. This makes assembly of the drive assembly simpler and more convenient. Specifically, the drive assembly includes a drive motor 41 and a gear 42 connected to the drive shaft of the drive motor 41. The end of the damper 32 is provided with a rack 321 that meshes with the gear 42. In this embodiment, the drive motor 41 is fixed to the bracket 31, and the gear 42 is rotatably connected to the bracket 31 to rotate under the drive of the drive motor 41. The rack 321 can be protruded from the back of the damper 32 and extend along the moving direction of the damper 32. The gear 42 is engaged with the rack 321 to convert the rotation of the driving shaft of the drive motor 41 into the sliding of the damper 32, thereby improving the structural strength of the drive assembly and improving the driving stability.

[0046] In actual application, a slide rail extending along the movable direction of the damper 32 is protruded from the end of the bracket 31, and a slide groove adapted to the slide rail is provided on the rack 321. In this embodiment, the slide rail extends along the width direction of the bracket 31, and the slide groove is provided on the side wall of the rack 321 facing the bracket 31 and extends along the length direction of the rack 321. The slide groove cooperates with the slide rail to achieve sliding cooperation between the damper 32 and the bracket 31, thereby improving the sliding stability of the damper 32. Specifically, as Figure 5 As shown, the sidewalls of the slide rail are provided with anti-wear ribs for contacting the inner wall of the chute. Multiple anti-wear ribs can be provided, spaced apart along the length of the slide rail to reduce the contact area between the entire slide rail and the inner wall of the chute, thereby reducing frictional resistance caused by sliding friction and improving the driving efficiency of the damper 32.

[0047] like Figure 5As shown, the drive assembly also includes a mounting plate 43, and the drive motor 41 and the gear 42 are both arranged on the mounting plate 43. The drive assembly also includes a mounting plate 43, and the drive motor 41 and the gear 42 are both arranged on the mounting plate 43. In this embodiment, the mounting plate 43 is covered at the end of the bracket 31, and the gear 42 is hidden between the mounting plate 43 and the bracket 31. The drive motor 41 is installed on the outside of the mounting plate 43, and the drive shaft of the drive motor 41 passes through the through hole of the mounting plate 43 and is connected to the gear 42. In this way, the drive shaft and gear 42 of the drive motor 41 can be hidden to avoid obstruction of the rotation process, so as to further improve the stability of the driving process. Of course, during the assembly process, the drive motor 41 and the gear 42 can be assembled on the mounting plate 43 first, and then assembled as a whole on the bracket 31, so that the assembly of the drive device is simpler and more convenient. In actual applications, such as Figure 4 As shown, the damper 32 can slide laterally to block or close the air outlet 311 , and the driving components are installed on the top and bottom of the bracket 31 , thereby further improving the driving strength of the damper 32 .

[0048] The air outlet component also includes a grille and / or an air guide plate provided at the air outlet 311. In this embodiment, the grille can prevent the user's hand from reaching into the shell from the air outlet 111 to improve the safety of the air-conditioning indoor unit.
