[0067] Embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0068] The following disclosure provides many different embodiments or examples for implementing different structures of the present invention. To simplify the disclosure of the present invention, components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numerals and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between various embodiments and / or settings discussed. In addition, the present invention provides examples of various specific processes and materials, but those of ordinary skill in the art can realize the applicability of other processes and / or the use of other materials.

[0069] Next, an air conditioner indoor unit 200 according to an embodiment of the present invention will be described with reference to the accompanying drawings. In the following description, the air conditioner indoor unit 200 is taken as an example of an air conditioner cabinet unit. After reading the following technical solutions, those skilled in the art can understand that the air conditioner indoor unit 200 is a technical solution of other types.

[0070] As Figure 1 and Figure 2 shown, the air conditioner indoor unit 200 includes a housing 1. The housing 1 includes a front panel 11 and a back panel 12. The front panel 11 and the back panel 12 are oppositely arranged, and the front panel 11 is fixedly installed on the back panel 12. For example, in the examples of Figure 1 and Figure 2 , the front panel 11 and the back panel 12 are oppositely arranged in the front-rear direction, and the front panel 11 is located on the front side of the back panel 12. The front panel 11 is directly fixedly installed on the back panel 12. Thus, compared with some technologies in which an air conditioner indoor unit is provided with a front panel bracket and the front panel needs to be pre-assembled with the front panel bracket and then assembled to the back panel; in the present application, by directly fixedly installing the front panel 11 on the back panel 12, it is possible not to provide a front panel bracket, reducing the number of components of the air conditioner indoor unit 200, which is beneficial to simplifying the structure of the air conditioner indoor unit 200, reducing the material consumption of the air conditioner indoor unit 200, reducing the material cost, and at the same time reducing the pre-assembly process of the front panel 11, thereby simplifying the assembly process of the air conditioner indoor unit 200, saving the assembly man-hours of the front panel 11, effectively improving the production efficiency of the air conditioner indoor unit 200, and moreover, not requiring a mold for processing the front panel bracket, reducing the mold cost.

[0071] Among them, an air outlet 11a is formed on the panel 11, and the air conditioner indoor unit 200 can blow air through the air outlet 11a. The air inlet of the air conditioner indoor unit 200 can be formed on the back panel 12, but is not limited thereto.

[0072] As Figure 1 and Figure 2 shown, the air conditioner indoor unit 200 further includes an air duct component 2 and an air outlet frame component 3. The air duct component 2 is disposed in the housing 1, and the air duct component 2 defines an air duct 20 communicating with the air outlet 11a. The air outlet frame component 3 includes an air outlet frame 31. The air outlet frame 31 is disposed between the panel 11 and the air duct component 2, and an air outlet passage 310 communicating the air outlet 11a and the air duct 20 is formed on the air outlet frame 31 to realize the normal air blowing of the air conditioner indoor unit 200.

[0073] Among them, the air outlet frame 31 is fixedly installed on the air duct component 2, which is convenient for ensuring the installation reliability of the air outlet frame 31 and is beneficial to realizing the stable operation of the air conditioner indoor unit 200; and the air outlet frame 31 is in limit fit with the panel 11, which can prevent the air outlet frame 31 from shaking relative to the panel 11 during the operation of the air conditioner indoor unit 200, thereby being beneficial to improving the operation stability of the air conditioner indoor unit 200.

[0074] It should be noted that "the air outlet frame 31 is fixedly installed on the air duct component 2" can be understood as that after the air outlet frame 31 is installed on the air duct component 2 by a fixing means, the air outlet frame 31 will not separate from the air duct component 2 under the action of an external force. Obviously, the air outlet frame 31 and the air duct component 2 are two independent structural parts respectively; "the air outlet frame 31 is in limit fit with the panel 11" can be understood as that after the air outlet frame 31 is in limit fit with the panel 11, the air outlet frame 31 can be separated from the panel 11 under the action of an external force to realize flexible disassembly and assembly.

[0075] Thus, for the air conditioner indoor unit 200 according to the embodiment of the present invention, by directly fixedly installing the panel 11 on the back panel 12, a separate panel bracket can be omitted, which is beneficial to simplifying the assembly process of the air conditioner indoor unit 200, improving the production efficiency and reducing the mold cost; by fixedly installing the air outlet frame 31 on the air duct component 2 and making the air outlet frame 31 in limit fit with the panel 11, on the premise of ensuring the reliable installation of the air outlet frame 31, the air outlet frame 31 can be prevented from shaking relative to the panel 11 during the operation, which is beneficial to improving the operation stability of the air conditioner indoor unit 200, and at the same time, the installation process of the air outlet frame 31 is relatively simple and easy to implement.

[0076] For example, in Figure 1 and Figure 2In the example, since there is no need to set the panel bracket, the material cost can be saved by 24 yuan. The pre-installation process of the panel 11 is saved, so the man-hour can be saved by 34 s and 3 operators can be reduced. Since it costs about 1.2 million yuan to manufacture the mold required for separately processing the panel bracket and about 0.5 million yuan to manufacture the mold required for separately processing the air outlet frame 31, in this application, there is no need to manufacture the mold required for separately processing the panel bracket, but the mold required for separately processing the air outlet frame 31 needs to be manufactured, so the mold cost can be relatively saved by about 700,000 yuan.

[0077] In some embodiments, such as Figure 3 and Figure 5 shown, the panel 11 has a first assembly surface 110, the back plate 12 has a second assembly surface 120, and the panel 11 is fixedly installed on the back plate 12 so that the first assembly surface 110 abuts against the second assembly surface 120, which is beneficial to ensuring the assembly tightness and assembly stability between the panel 11 and the back plate 12. For example, the panel 11 is hooked and cooperated with the back plate 12 through the first hooking component 5, and the panel 11 is tightly connected to the back plate 12 through the first connecting component 6 so that the first assembly surface 110 abuts against the second assembly surface 120, thereby facilitating the disassembly and assembly between the panel 11 and the back plate 12 and ensuring the reliable connection between the panel 11 and the back plate 12.

[0078] For example, when the panel 11 and the back plate 12 are assembled, the panel 11 and the back plate 12 can be hooked and cooperated through the first hooking component 5, and the panel 11 is tightly connected to the back plate 12 through the first connecting component 6; when the panel 11 and the back plate 12 are disassembled, the first connecting component 6 is loosened and disassembled, and the panel 11 is separated from the back plate 12 to disassemble the panel 11 and the back plate 12. Thus, the first hooking component 5 and the first connecting component 6 can simultaneously bear the assembly force between the panel 11 and the back plate 12, which is beneficial to ensuring the assembly reliability of the panel 11 and the back plate 12. Moreover, the first hooking component 5 is convenient for realizing the limit between the panel 11 and the back plate 12, which is beneficial to improving the installation efficiency of the panel 11. At the same time, the number of the first connecting components 6 can be reduced. The first hooking component 5 is convenient for disassembly and assembly, simplifies the disassembly and assembly process between the panel 11 and the back plate 12, makes the disassembly and assembly of the air conditioner indoor unit 200 simple and convenient, and is beneficial to further improving the assembly efficiency.

[0079] In some embodiments, such as Figure 3 and Figure 5As shown, the first hooking component 5 includes a first hook 51 and a first locking member 52. The first hook 51 is provided on one of the front panel 11 and the back panel 12, and the first hook 51 includes a first supporting portion 511 and a first limiting portion 512. The first supporting portion 511 extends in the direction towards the other one of the front panel 11 and the back panel 12, and the first limiting portion 512 extends upward or downward from the first supporting portion 511. The first locking member 52 is provided on the other one of the front panel 11 and the back panel 12, and the first locking member 52 is in hooking cooperation with the first hook 51.

[0080] For example, in the examples of Figure 3 and Figure 5 , the first hook 51 is provided on the front panel 11, and the first hook 51 is located at the rear side of the front panel 11. The first supporting portion 511 extends horizontally in the direction towards the back panel 12 (for example, the first supporting portion 511 extends horizontally from front to back), and the first limiting portion 512 extends vertically downward or obliquely downward from the free end of the first supporting portion 511, so that the first hook 51 can be generally formed into an L-shaped structure, and the first hook 51 can define a first limiting groove 510 with an opening facing downward; the first locking member 52 is provided on the back panel 12, and the first locking member 52 is located at the front side of the back panel 12. The first limiting portion 512 can be engaged with the side of the first locking member 52 away from the front panel 11 to achieve the hooking cooperation between the first locking member 52 and the first hook 51. Thus, the first hooking component 5 has a simple structure and is convenient for disassembly and assembly.

[0081] Of course, the first hook 51 can also be provided on the back panel 12, and the first locking member 52 is provided on the front panel 11; the first limiting portion 512 can also extend vertically upward or obliquely upward from the free end of the first supporting portion 511.

[0082] In some embodiments, as shown in Figure 3 and Figure 5 , the first locking member 52 has a first locking hole 52a, the first locking hole 52a can penetrate through the first locking member 52, the first limiting portion 512 extends from the first locking hole 52a to the side of the first locking member 52 away from one of the front panel 11 and the back panel 12, and the first limiting portion 512 cooperates with the first locking member 52, so that the first locking member 52 is engaged with the first limiting groove 510 to achieve the assembly of the first hooking component 5.

[0083] For example, in the examples of Figure 3 and Figure 5 , the first hook 51 is provided on the front panel 11, the first locking member 52 is provided on the back panel 12, the first limiting portion 512 extends from the first locking hole 52a from front to back to the side of the first locking member 52 away from the front panel 11, so that the first locking member 52 is engaged with the first limiting groove 510, and the first limiting portion 512 can be stuck on the side of the first locking member 52 away from the front panel 11 to ensure the reliable assembly of the first hooking component 5.

[0084] It can be understood that when there are multiple first hooks 51, there are also multiple first locking members 52. The multiple first locking members 52 can be arranged at intervals respectively, or the multiple first locking members 52 can be connected to form an integral part. For example, when the multiple first locking members 52 can be connected to form an integral part, the integral part can have multiple first locking holes 52a, and the multiple first locking holes 52a are respectively in corresponding cooperation with the multiple first hooks 51. Among them, in the description of the present application, the meaning of "multiple" is two or more.

[0085] In some embodiments, as Figure 3 and Figure 5 shown, the first hook 51 is provided on the panel 11, the first assembly surface 110 is located at one end of the first support portion 511 away from the first limiting portion 512, then the first support portion 511 can be provided on the first assembly surface 110, the first locking member 52 is provided on the back plate 12, and one side surface of the first locking member 52 facing the first hook 51 is formed as the second assembly surface 120. Thus, when the panel 11 is hooked and cooperated with the back plate 12 through the first hooking assembly 5, it is convenient to ensure that the first assembly surface 110 and the second assembly surface 120 are in abutment.

[0086] In some embodiments, as Figures 3 - 5 shown, the first connection assembly 6 includes a first connecting member, and the first connecting member passes through the panel 11 and the back plate 12 to fasten and connect the panel 11 and the back plate 12. Then, when the panel 11 and the back plate 12 are assembled, the panel 11 and the back plate 12 can be first hooked and cooperated through the first hooking assembly 5, and then the panel 11 can be fixedly connected to the back plate 12 through the first connecting member, ensuring reliable connection between the panel 11 and the back plate 12. Optionally, the first connecting member can be a threaded connecting member such as a screw, a bolt, etc.

[0087] For example, in the example of Figures 3 - 5 , a first connection hole 6210 is formed on the panel 11, a second connection hole 6220 is formed on the back plate 12, and the first connecting member passes through the first connection hole 6210 and the second connection hole 6220 to realize the fixed connection between the panel 11 and the back plate 12.

[0088] In some embodiments, as Figures 3 - 5 shown, the first connection assembly 6 further includes a limiting structure 62. The panel 11 and the back plate 12 are in limiting cooperation through the limiting structure 62, and the first connecting member passes through the limiting structure 62, which facilitates the installation of the first connecting member and at the same time facilitates the first connection assembly 6 to form an integral whole, ensuring the connection reliability of the first connection assembly 6.

[0089] In some embodiments, as Figure 3 and Figure 5As shown, the limiting structure 62 includes a limiting block 621 and a limiting member 622. The limiting block 621 is provided on one of the front panel 11 and the back panel 12, and a limiting protrusion 6211 is formed on the limiting block 621. The limiting member 622 is provided on the other of the front panel 11 and the back panel 12, and a limiting hole 6221 is formed on the limiting member 622. The limiting hole 6221 is in limiting cooperation with the limiting protrusion 6211. The first connecting member passes through the limiting block 621 and the limiting member 622 to tightly connect the limiting block 621 and the limiting member 622; for example, in Figure 3 and Figure 5 In the example of, a first connection hole 6210 is formed on the limiting block 621, a second connection hole 6220 is formed on the limiting member 622, and the first connecting member passes through the first connection hole 6210 and the second connection hole 6220 to realize the fixed connection of the front panel 11 and the back panel 12. Thus, the limiting structure 62 has a simple structure, reliable limiting, and is easy to implement.

[0090] For example, in Figure 3 and Figure 5 In the example of, the limiting protrusion 6211 can be formed on the lower surface of the limiting block 621 and protrude downward, the top side of the limiting hole 6221 is open, and the limiting protrusion 6211 is fitted into the limiting hole 6221 from top to bottom, which is beneficial to improving the limiting reliability of the front panel 11 and the back panel 12 and further facilitating the installation of the first connecting member.

[0091] In some embodiments, as Figure 4 shown, the first hooking assembly 5 is provided on both width sides of the housing 1, and the first connecting assembly 6 is provided on one length side of the housing 1, so that the first hooking assembly 5 and the first connecting assembly 6 are relatively dispersed, and the acting force borne by the front panel 11 or the back panel 12 is relatively dispersed, which is beneficial to improving the force on the front panel 11 and the back panel 12 and avoiding damage to the front panel 11 or the back panel 12 due to overly concentrated force.

[0092] For example, in Figure 4 the example of, a plurality of first hooking assemblies 5 are respectively provided on both width sides of the housing 1, and the plurality of first hooking assemblies 5 on the same width side of the housing 1 are arranged along the length direction of the housing 1; the first connecting assembly 6 is provided on the top side of the housing 1, and the first connecting assembly 6 can be multiple, and the multiple first connecting assemblies 6 can be arranged along the width direction of the housing 1. Of course, the first connecting assembly 6 can also be one.

[0093] In some embodiments, as Figure 1 and Figure 2As shown, the housing 1 further includes a top cover 13. The top cover 13 is provided at the top of the front panel 11 and the rear panel 12. The top edge of the front panel 11 extends inwards to form a first reinforcing ring 112, and the top edge of the rear panel 12 extends inwards to form a second reinforcing ring 122. Then, the first reinforcing ring 112 is provided at the top of the front panel 11 and extends inwards from the top edge of the front panel 11, and the second reinforcing ring 122 is provided at the top of the rear panel 12 and extends inwards from the top edge of the rear panel 12. Among them, the top cover 13 is fixedly connected to the first reinforcing ring 112 and the second reinforcing ring 122 respectively through a second connecting member. That is, the top cover 13 is fixedly connected to the first reinforcing ring 112 through a second connecting member, and the top cover 13 is fixedly connected to the second reinforcing ring 122 through a second connecting member. Thus, by providing the first reinforcing ring 112, the structural strength and stability of the front panel 11 are enhanced, and the reliable connection between the front panel 11 and the top cover 13 is facilitated. Similarly, by providing the second reinforcing ring 122, the structural strength and stability of the rear panel 12 are enhanced, and the reliable connection between the rear panel 12 and the top cover 13 is facilitated. Optionally, the second connecting member can be a threaded connecting member such as a screw or a bolt.

[0094] It should be noted that the direction "inwards" can be understood as the direction towards the central axis of the air conditioner indoor unit 200.

[0095] In Figure 4 the example of, a first reinforcing ring 112 can also be formed at the bottom of the front panel 11 to further improve the structural strength of the front panel 11.

[0096] As Figure 1 and Figure 2 shown, the housing 1 further includes a chassis 14. The chassis 14 is provided at the bottom of the front panel 11 and the rear panel 12. The chassis 14 is fixedly connected to the front panel 11 through a third connecting member. Then, the assembly between the chassis 14 and the front panel 11 is simple, and it is convenient to ensure that the housing 1 forms an integral body, ensuring the structural stability of the air conditioner indoor unit 200. For example, in Figure 4 the example of, mounting holes 11b are formed at the bottom of the front panel 11, and the third connecting member passes through the mounting holes 11b and is fixedly connected to the chassis 14. Optionally, the third connecting member can be a threaded connecting member such as a screw or a bolt.

[0097] Among them, the chassis 14 and the rear panel 12 can also be fixedly connected through a threaded connecting member.

[0098] For example, in Figures 3 - 5In the example, the housing 1 includes a front panel 11 and a back panel 12. The front panel 11 is hook-fitted with the back panel 12 through a first hook assembly 5, and the front panel 11 is fixedly connected to the back panel 12 through a first connection assembly 6. The first hook assembly 5 includes a first hook 51 and a first locking member 52. The first hook 51 is provided on the front panel 11. A plurality of first hooks 51 are respectively provided on both widthwise sides of the front panel 11 (for example, Figure 1 the left and right sides in Figure 1 ). The plurality of first hooks 51 on the same widthwise side of the front panel 11 are spaced apart along the lengthwise direction of the front panel 11 (for example,

[0099] the up and down direction in

[0100] ). The first locking member 52 is provided on the back panel 12, and the first locking member 52 has a first locking hole 52a. The first locking hole 52a penetrates through a second assembly surface 120 on the back panel 12. Each first hook 51 is respectively correspondingly fitted with a first locking hole 52a. The first connection assembly 6 includes a first connecting member and a limiting structure 62. The limiting structure 62 is provided at the top of the front panel 11 and the back panel 12. The first connecting member passes through the limiting structure 62 to fixedly connect the front panel 11 and the back panel 12.

[0099] Wherein, the first hook 51 includes a first supporting portion 511 and a first limiting portion 512. The first supporting portion 511 extends horizontally in the direction towards the back panel 12, and the first limiting portion 512 extends downward from the free end of the first supporting portion 511. The limiting structure 62 includes a limiting block 621 and a limiting member 622. The limiting block 621 is provided on the front panel 11, and a limiting protrusion 6211 extending downward is formed on the bottom surface of the limiting block 621. The limiting member 622 is provided on the back panel 12, and a limiting hole 6221 with an open top side is formed on the limiting member 622. The limiting protrusion 6211 is limit-fitted in the limiting hole 6221 from top to bottom. When the front panel 11 and the back panel 12 are assembled, the front panel 11 and the back panel 12 can be first hook-fitted through the first hook assembly 5 and limit-fitted through the limiting structure 62, and then the front panel 11 is fixedly connected to the back panel 12 through the first connecting member. Of course, when the first limiting portion 512 extends upward from the free end of the first supporting portion 511, the limiting protrusion 6211 can be formed on the top surface of the limiting block 621 and extend upward.

[0100] In Figures 1 - 3 and Figure 5In the example, the housing 1 further includes a top cover 13 and a chassis 14. The appearance surfaces of the front panel 11 and the back panel 12 are both formed as curved surfaces. For example, both the front panel 11 and the back panel 12 are formed as curved plate structures. The first reinforcing ring 112 extends inward from the top edge of the front panel 11, and the second reinforcing ring 122 extends inward from the top edge of the back panel 12. Then, both the first reinforcing ring 112 and the second reinforcing ring 122 can be formed as open annular structures. For example, both the first reinforcing ring 112 and the second reinforcing ring 122 are formed as C-shaped structures. A first fixing hole 112a is formed on the first reinforcing ring 112, and the second connecting member fixes and connects the front panel 11 and the top cover 13 through the first fixing hole 112a. A second fixing hole 122a is formed on the second reinforcing ring 122, and the second connecting member fixes and connects the back panel 12 and the top cover 13 through the second fixing hole 122a. Among them, the limiting block 621 is one or more, and the limiting block 621 is provided at the opening of the first reinforcing ring 112. The limiting member 622 is provided at the opening of the second reinforcing ring 122. For example, a first support rod 111 is further provided at the top of the front panel 11. The first support rod 111 is connected between the circumferential two ends of the front panel 11. Then, the first support rod 111 is provided at the opening of the first reinforcing ring 112. A second support rod 121 is provided at the top of the back panel 12. The second support rod 121 is connected between the circumferential two ends of the back panel 12. Then, the second support rod 121 is provided at the opening of the second reinforcing ring 122. The limiting block 621 is formed on the first support rod 111, and the limiting member 622 is formed on the second support rod 121.

[0101] In some embodiments, as Figure 1 and Figure 12 shown, the air conditioner indoor unit 200 further includes a switch door assembly 4. The switch door assembly 4 includes a switch door 41 and a first driving device 42. The switch door 41 is movably installed on the air outlet frame 31. Then, the switch door 41 can move relative to the air outlet frame 31. The first driving device 42 is provided on the air outlet frame 31, and the first driving device 42 is used to drive the switch door 41 to move so that the switch door 41 opens or closes the air outlet 11a. Thus, compared with some technologies in which the air conditioner indoor unit is provided with a panel bracket, and structures such as the front panel and the switch door assembly of the air conditioner indoor unit are all installed on the panel bracket, and the panel bracket needs to be compatible with all assembly structures, resulting in a relatively large volume and high material cost of the panel bracket. Therefore, in this application, by installing the switch door assembly 4 on the air duct component 2, it effectively meets the requirement that the air conditioner indoor unit 200 does not need to be provided with a panel bracket, simplifies the assembly process of the air conditioner indoor unit 200, has a lower cost, and is also beneficial to saving the occupied space of the air conditioner indoor unit 200.

[0102] In some embodiments, as Figure 1 and Figure 12As shown, the air outlet frame component 3 further includes a wind guiding component 32. The wind guiding component 32 is arranged at the air outlet 11a, and the wind guiding component 32 includes a wind guiding plate 321 and a second driving device 322. The wind guiding plate 321 is rotatably installed on the air outlet frame 31, and the second driving device 322 is arranged on the air outlet frame 31 and is used to drive the wind guiding plate 321 to rotate, so as to guide the air flow at the air outlet 11a. Thus, compared with some technologies where the air conditioner indoor unit is provided with a panel bracket, and the panel and the wind guiding component of the air conditioner indoor unit are all installed on the panel bracket, and the panel bracket needs to be compatible with all assembly structures, resulting in a relatively large volume and high material cost of the panel bracket. Therefore, in this application, by installing the wind guiding component 32 on the air duct component 2, it effectively meets the requirement that the air conditioner indoor unit 200 does not need to be provided with a panel bracket, simplifies the assembly process of the air conditioner indoor unit 200, and at the same time helps to save the occupied space of the air conditioner indoor unit 200.

[0103] For example, in Figure 1 and Figure 12 example, the switch door component 4 and the wind guiding component 32 of the air conditioner indoor unit 200 are both installed on the air outlet frame 31.

[0104] In some embodiments, as Figure 11 shown, a first overlapping portion 211 is formed on the air duct component 2, and a second overlapping portion 311 is formed on the air outlet frame 31. The air outlet frame 31 is fixedly installed on the air duct component 2, so that the second overlapping portion 311 is overlapped and matched with the first overlapping portion 211, which is convenient for ensuring the sealing performance between the air duct component 2 and the air outlet frame 31 and avoiding air leakage between the air duct component 2 and the air outlet frame 31.

[0105] For example, in Figure 11 example, the first overlapping portion 211 can be formed at the edge of one end of the air duct 20 communicating with the air outlet channel 310. The first overlapping portion 211 can include a first overlapping sub-portion 211a and a second overlapping sub-portion 211b. The first overlapping sub-portion 211a and the second overlapping sub-portion 211b are respectively located on both sides of the width of the above-mentioned one end of the air duct 20 (for example, Figure 11 the left and right sides in), the second overlapping portion 311 can be formed at the edge of one end of the air outlet channel 310 communicating with the air duct 20. The second overlapping portion 311 can include a third overlapping sub-portion 311a and a fourth overlapping sub-portion 311b. The third overlapping sub-portion 311a and the fourth overlapping sub-portion 311b are respectively located on both sides of the width of the above-mentioned one end of the air outlet channel 310; the first overlapping sub-portion 211a411a is overlapped and matched with the third overlapping sub-portion 311a, so that at least one sealing mating surface is formed between the first overlapping sub-portion 211a and the third overlapping sub-portion 311a, and the second overlapping sub-portion 211b is overlapped and matched with the fourth overlapping sub-portion 311b, so that at least one sealing mating surface is formed between the second overlapping sub-portion 211b and the fourth overlapping sub-portion 311b.

[0106] As Figure 11 shown, the air duct component 2 includes an air duct member 21. The first overlapping sub - portion 211a can extend outward from the corresponding edge of the air duct member 21. The third overlapping sub - portion 311a can extend outward from the corresponding edge of the air outlet frame 31 and then extend towards the air duct member 21 to exceed the first overlapping sub - portion 211a. The third overlapping sub - portion 311a can be docked with the first overlapping sub - portion 211a, so that the side surface of the third overlapping sub - portion 311a abuts against the side surface of the first overlapping sub - portion 211a. The second overlapping sub - portion 211b can extend from the corresponding edge of the air duct member 21 to form a first V - shaped structure. The fourth overlapping sub - portion 311b can extend from the corresponding edge of the air outlet frame 31 corresponding to the air outlet channel 310 to form a second V - shaped structure. The third overlapping sub - portion 311a is docked with the fourth overlapping sub - portion 311b, so that the end surface of one fork of the first V - shaped structure abuts against the end surface of one fork of the second V - shaped structure, and the side surface of the other fork of the first V - shaped structure abuts against the end surface of the other fork of the second V - shaped structure. Optionally, a support rib can be provided inside the first V - shaped structure. The support rib supports between the two forks of the first V - shaped structure, which is beneficial to improving the structural strength of the first V - shaped structure. Wherein, the lengths of the two forks of the first V - shaped structure and the second V - shaped structure can be specifically set according to actual applications respectively.

[0107] Of course, the structures of the first overlapping portion 211 and the second overlapping portion 311 are not limited to this.

[0108] As Figures 11 - 13 shown, the air outlet frame 31 is hook - fitted with the air duct component 2 through the second hook - hanging assembly 7, and the air outlet frame 31 is fixedly connected to the air duct component 2 through the second connection assembly, so that the second overlapping portion 311 is overlapped and fitted with the first overlapping portion 211. For example, in the Figure 11 example, the air duct component 2 includes an air duct member 21. An air duct 20 is defined inside the air duct member 21. The air wheel (such as a cross - flow air wheel) of the air duct component 2 is arranged inside the air duct member 21. The air outlet frame 31 can be limited and fitted with the air duct member 21 through the second hook - hanging assembly 7, which is convenient for the installation of the second connection assembly, beneficial to improving the installation efficiency of the air outlet frame 31. Moreover, the second hook - hanging assembly 7 and the second connecting member can simultaneously bear the assembly acting force between the air outlet frame 31 and the air duct component 2, which is beneficial to ensuring the assembly reliability of the air outlet frame 31 and the air duct component 2. In addition, the number of the second connection components can be reduced. Since the second hook - hanging assembly 7 is convenient for disassembly and assembly, the disassembly and assembly process between the air outlet frame 31 and the air duct component 2 is simplified, making the disassembly and assembly of the indoor air conditioner 200 simple and convenient, which is beneficial to further improving the assembly efficiency.

[0109] In some embodiments, as Figures 11 - 13As shown, the second hooking component 7 includes a second hook 71 and a second locking member 72. The second hook 71 is provided on one of the air outlet 11a and the duct component 2, and the second hook 71 includes a second supporting portion 711 and a second limiting portion 712. The second supporting portion 711 extends towards the other of the air outlet frame 31 and the duct component 2, and the second limiting portion 712 extends upward or downward from the second supporting portion 711. The second locking member 72 is provided on the other of the air outlet frame 31 and the duct component 2, and the second locking member 72 is in hook engagement with the second hook 71.

[0110] For example, in Figures 11 - 13 the example, the second hook 71 is provided on the air outlet frame 31. The second supporting portion 711 extends horizontally towards the duct component 2, and the second limiting portion 712 extends vertically downward or obliquely downward from the free end of the second supporting portion 711, so that the second hook 71 can be generally formed into an L-shaped structure, and the second hook 71 can define a second limiting groove 710 with an opening facing downward; the second locking member 72 is provided on the duct component 2, and the second limiting portion 712 can be fitted on the side of the second locking member 72 away from the air outlet frame 31 to achieve the hook engagement between the second locking member 72 and the second hook 71. Thus, the second hooking component 7 has a simple structure and is convenient for disassembly and assembly.

[0111] Of course, the second hook 71 can also be provided on the duct component 2, and the second locking member 72 is provided on the air outlet frame 31; the second limiting portion 712 can also extend vertically upward or obliquely upward from the free end of the second supporting portion 711.

[0112] In some embodiments, as Figure 13 shown, there are multiple second locking members 72, and each second locking member 72 is respectively engaged with a second hook 71. The multiple second locking members 72 include a first sub-locking member 721 and a second sub-locking member 722. The first sub-locking member 721 has a second locking hole 721a, and the second locking hole 721a can penetrate the first sub-locking member 721. The second limiting portion 712 extends from the second locking hole 721a to the side of the first sub-locking member 721 away from one of the air outlet frame 31 and the duct component 2, and the second limiting portion 712 is engaged with the first sub-locking member 721, so that the first sub-locking member 721 is fitted into the second limiting groove 710 of the corresponding second hook 71 to achieve the assembly of the second hooking component 7; the second limiting portion 712 extends from the upper side or the lower side of the second sub-locking member 722 to the side of the second sub-locking member 722 away from one of the air outlet frame 31 and the duct component 2, and the second limiting portion 712 is engaged with the second sub-locking member 722, so that the second sub-locking member 722 is fitted into the second limiting groove 710 of the corresponding second hook 71 to achieve the assembly of the second hooking component 7.

[0113] For example, in Figure 12 and Figure 13In the example, the second hook 71 is provided on the air outlet frame 31, the second locking member 72 is provided on the air duct member 2, and the second limiting portion 712 of the second hook 71 corresponding to the first sub-locking member 721 extends from the second locking hole 721a forward and backward to the side of the first sub-locking member 721 away from the air outlet frame 31, so that the first sub-locking member 721 is fitted into the second limiting groove 710, and the second limiting portion 712 can be stuck on the side of the first sub-locking member 721 away from the air outlet frame 31, ensuring the reliable assembly of the second hook assembly 7; the second limiting portion 712 of the second hook 71 corresponding to the second sub-locking member 722 extends from the upper side of the second sub-locking member 722 to the side of the second sub-locking member 722 away from the air outlet frame 31, so that the second sub-locking member 722 is fitted into the second limiting groove 710, and the second limiting portion 712 can be stuck on the side of the second sub-locking member 722 away from the air outlet frame 31.

[0114] It can be understood that when there are multiple first sub-locking members 721, the multiple first sub-locking members 721 can be arranged at intervals respectively, or the multiple first sub-locking members 721 can be connected to form an integral part; for example, when the multiple first sub-locking members 721 can be connected to form an integral part, the integral part can have multiple second locking holes 721a, and the multiple second locking holes 721a are respectively corresponding and fitted with the multiple second hooks 71.

[0115] In Figure 13 the example, the first sub-locking member 721 and the second sub-locking member 722 are respectively multiple. The multiple first sub-locking members 721 are all located on one side of the width of the cross-section of the air duct 20, and the multiple first sub-locking members 721 are arranged in sequence along the length direction of the cross-section of the air duct 20. The multiple second sub-locking members 722 are all located on the other side of the width of the cross-section of the air duct 20, and the multiple second sub-locking members 722 are arranged at intervals along the length direction of the cross-section of the air duct 20.

[0116] In some embodiments, as Figure 12 and Figure 13 shown, the second connection assembly includes a fourth connecting member. The fourth connecting member passes through the air outlet frame 31 and the air duct member 2 to firmly connect the air outlet frame 31 and the air duct member 2, which is convenient for ensuring the structural stability of the air conditioner indoor unit 200. Optionally, the fourth connecting member can be a threaded connecting member such as a screw, a bolt, etc.

[0117] In Figure 12 and Figure 13In the example, the fourth connecting member can be provided at the communication port between the air outlet passage 310 and the air duct 20. Then, a third fixing hole 21a is formed on the air duct component 2. The third fixing hole 21a is located at the outlet end of the air duct 20. A fourth fixing hole 31a is formed on the air outlet frame 31. The fourth fixing hole 31a is located at the air inlet end of the air outlet passage. The fourth connecting member passes through the third fixing hole 21a and the fourth fixing hole 31a to realize the fixed connection between the air outlet frame 31 and the air duct component 2. Of course, the second connecting member can also be provided at other positions, and is not limited thereto.

[0118] In some embodiments, such as Figures 6 - 9 As shown, the air outlet frame 31 is hooked and cooperated with the panel 11 through the third hooking assembly 8 to realize the limiting cooperation between the air outlet frame 31 and the panel 11. Thus, on the premise of ensuring reliable limiting between the air outlet frame 31 and the panel 11, it is convenient to realize the flexible disassembly and assembly of the air outlet frame 31 and the panel 11.

[0119] Such as Figures 7 - 9 As shown, the third hooking assembly 8 includes a third hook 81 and a third locking member 82. The third hook 81 is provided on one of the air outlet frame 31 and the panel 11. And the third hook 81 includes a third supporting portion 811 and a third limiting portion 812. The third supporting portion 811 extends towards the other one of the air outlet frame 31 and the panel 11. The third limiting portion 812 extends upward or downward from the third supporting portion 811. The third locking member 82 is provided on the other one of the air outlet frame 31 and the panel 11. And the third locking member 82 is hooked and cooperated with the third hook 81.

[0120] For example, in Figures 7 - 9 the example, the third hook 81 is provided on the panel 11, and the third hook 81 is located at the rear side of the panel 11. The third supporting portion 811 extends horizontally towards the air outlet frame 31. The third limiting portion 812 extends vertically downward or obliquely downward from the free end of the third supporting portion 811, so that the third hook 81 can be generally formed into an L-shaped structure, and the third hook 81 can define a third limiting groove 810 with an opening facing downward; the third locking member 82 is provided on the air outlet frame 31, and the third locking member 82 is located at the front side of the air outlet frame 31. The third limiting portion 812 can be fitted on the side of the third locking member 82 away from the panel 11 to realize the hooking cooperation between the third locking member 82 and the third hook 81. Thus, the structure of the third hooking assembly 8 is simple and the disassembly and assembly are convenient.

[0121] Of course, the third hook 81 can also be provided on the air outlet frame 31, and the third locking member 82 is provided on the panel 11; the third limiting portion 812 can also extend vertically upward or obliquely upward from the free end of the third supporting portion 811.

[0122] In some embodiments, such as Figure 8As shown, there are multiple third locking members 82, and each third locking member 82 is respectively engaged with a third hook 81. The multiple third locking members 82 include a third sub-locking member 821 and a fourth sub-locking member 822. The third sub-locking member 821 has a third locking hole 821a, and the third locking hole 821a can penetrate the third sub-locking member 821. The third limiting portion 812 extends from the third locking hole 821a to one side of the third sub-locking member 821 away from one of the air outlet frame 31 and the panel 11, and the third limiting portion 812 cooperates with the third sub-locking member 821, so that the third sub-locking member 821 is fitted into the third limiting groove 810 of the corresponding third hook 81 to realize the assembly of the third hook and hanging assembly 8; the third limiting portion 812 extends from the upper side or the lower side of the fourth sub-locking member 822 to one side of the third sub-locking member 821 away from one of the air outlet frame 31 and the panel 11, and the third limiting portion 812 cooperates with the fourth sub-locking member 822, so that the fourth sub-locking member 822 is fitted into the third limiting groove 810 of the corresponding third hook 81 to realize the assembly of the third hook and hanging assembly 8.

[0123] Thus, the structures of the third sub-locking member 821 and the fourth sub-locking member 822 can be different, which is convenient for realizing the diversified and flexible design of the third locking member 82.

[0124] For example, in Figures 7 - 9 the example, the third hook 81 is provided on the panel 11, the third locking member 82 is provided on the air outlet frame 31, and the third limiting portion 812 of the third hook 81 corresponding to the third sub-locking member 821 extends from the third locking hole 821a from front to back to one side of the third sub-locking member 821 away from the panel 11, so that the third sub-locking member 821 is fitted into the third limiting groove 810 of the corresponding third hook 81, and the third limiting portion 812 can be stuck on one side of the third sub-locking member 821 away from the panel 11 to ensure the reliable assembly of the third hook and hanging assembly 8; the third limiting portion 812 of the third hook 81 corresponding to the fourth sub-locking member 822 extends from the upper side of the fourth sub-locking member 822 to one side of the fourth sub-locking member 822 away from the panel 11, so that the fourth sub-locking member 822 is fitted into the third limiting groove 810 of the corresponding third hook 81, and the third limiting portion 812 can be stuck on one side of the fourth sub-locking member 822 away from the panel 11.

[0125] Among them, in Figure 9 the example, a card slot 822a can be formed on the fourth sub-locking member 822. The upper side of the card slot 822a is open and the card slot 822a penetrates the fourth sub-locking member 822 along the thickness direction of the fourth sub-locking member 822. The third limiting portion 812 of the third hook 81 corresponding to the fourth sub-locking member 822 can extend to one side of the fourth sub-locking member 822 away from the panel 11 through the card slot 822a. Of course, the card slot 822a may not be formed on the fourth sub-locking member 822.

[0126] It can be understood that when there are multiple third sub-lock members 821, the multiple third sub-lock members 821 can be arranged at intervals respectively, or the multiple third sub-lock members 821 can be connected to form an integral part; for example, when the multiple third sub-lock members 821 can be connected to form an integral part, the integral part can have multiple third lock holes 821a, and the multiple third lock holes 821a respectively cooperate with the multiple third hooks 81.

[0127] In some embodiments, as Figure 1 , Figures 6 - 9 shown, the air conditioner indoor unit 200 further includes a switch door assembly 4. The switch door assembly 4 includes a switch door 41 and a first driving device 42. The switch door 41 is movably installed on the air outlet frame 31, so the switch door 41 can move relative to the air outlet frame 31. The switch door 41 is located between the panel 11 and the air outlet frame 31. The first driving device 42 is arranged on the air outlet frame 31, and the first driving device 42 is used to drive the switch door 41 to move so that the switch door 41 opens or closes the air outlet 11a through one side of the width of the air outlet 11a (for example, Figure 1 the right side in Figure 1 ). That is to say, when the switch door 41 is in the position of closing the air outlet 11a, the first driving device 42 can drive the switch door 41 to move along the width direction of the air outlet 11a and make the switch door 41 move towards one side of the width of the air outlet 11a to open the air outlet 11a. At this time, the switch door 41 is located on one side of the width of the air outlet 11a. When the switch door 41 is in the position of opening the air outlet 11a, the first driving device 42 can drive the switch door 41 to move towards the other side of the width of the air outlet 11a until the switch door 41 closes the air outlet 11a. Obviously, during the movement of the switch door 41, the switch door 41 always passes through the above-mentioned one side of the width of the air outlet 11a, and the switch door 41 never passes through the above-mentioned other side of the width of the air outlet 11a (for example,

[0128] as Figure 8As shown, the third sub-lock 821 is correspondingly provided on the other side of the above-mentioned width of the air outlet 11a. At this time, the third sub-lock 821 can be provided on the panel 11 or the air outlet frame 31, and the third sub-lock 821 can be provided adjacent to the edge of the other side of the above-mentioned width of the air outlet 11a. Then, the cooperation between the third sub-lock 821 and the corresponding third hook 81 will not interfere with the movement of the switch door 41, ensuring the normal movement of the switch door 41. The fourth sub-lock 822 is provided on at least one side in the length direction of the air outlet 11a. At this time, the fourth sub-lock 822 can be provided on the panel 11 or the air outlet frame 31, and the fourth sub-lock 822 can be provided on one side in the length of the air outlet 11a or on both sides in the length of the air outlet 11a with the fourth sub-lock 822 provided respectively, and the fourth sub-lock 822 can be provided adjacent to the edge of the corresponding length side of the air outlet 11a. Then, the cooperation between the fourth sub-lock 822 and the corresponding third hook 81 will not interfere with the movement of the switch door 41, further ensuring the normal movement of the switch door 41.

[0129] As Figure 1 shown, an air inlet is formed on the back plate 12. An air inlet grille and a filter screen are provided at the air inlet. The heat exchange component 9 of the air conditioner indoor unit 200 is installed on the back plate 12, and the air duct component 2 is assembled with the heat exchange component 9 to ensure the stable structure and reliable use of the air conditioner indoor unit 200.
