[0055] Embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Embodiments of the present invention are described in detail below.

[0056] Reference below Figure 1-Figure 23 The air conditioner indoor unit 100 according to the embodiment of the present invention is described, and the air conditioner indoor unit 100 may be a wall-mounted air conditioner indoor unit. In the following description of the present application, the air conditioner indoor unit 100 is taken as an example of a wall-mounted air conditioner indoor unit.

[0057] like Figure 1-Figure 8 As shown, the air conditioner indoor unit 100 according to the embodiment of the present invention includes a housing 1 , an inner air guide plate 2 and an outer air guide plate 3 .

[0058] like Figure 2 and Figure 3 As shown, the housing 1 includes a first accommodating portion 11 having a first accommodating space and a second accommodating portion 12 having a second accommodating space. The first accommodating portion 11 has an air outlet 111 (such as Figure 4 The inner air guide plate 2 is rotatable between a first closed position in which the inner air guide plate 2 is accommodated in the first accommodation space and a first open position in which the air outlet 111 is opened. The outer air guide plate 3 is rotatable between a second closed position in which the outer air guide plate 3 is accommodated in the second accommodation space and a second open position in which the air outlet 111 is opened. When the inner air guide plate 2 is located at the first closed position and the outer air guide plate 3 is located at the second closed position, the inner air guide plate 2 is located at the rear side of the outer air guide plate 3 and is shielded by the outer air guide plate 3.

[0059] like Figure 3 As shown, a first accommodating portion 11 having a first accommodating space and a second accommodating portion 12 having a second accommodating space are located at the front side of the housing 1, and the second accommodating space is located at the front side of the first accommodating space. The inner air guide plate 2 is rotatably disposed in the first accommodating portion 11, and is used to control the opening and closing of the air outlet 111. The outer air guide plate 3 is rotatably disposed in the second accommodating portion 12, thereby reducing the size difference between the outer air guide plate 3 and the inner air guide plate 2. The inner air guide plate 2 is located at the rear side of the outer air guide plate 3. When the inner air guide plate 2 and the outer air guide plate 3 are both in the closed state, the outer air guide plate 3 blocks the inner air guide plate 2. At this time, the front side surface of the outer air guide plate 3 is flush with the front side surface of the housing 1, which effectively ensures the aesthetic appearance of the air conditioner indoor unit 100. It should be noted here that, in the description of this specification, when the user faces the air-conditioning indoor unit 100, the direction toward the user is called "front", and conversely, the direction away from the user is called "rear". Therefore, the second accommodating space is located on the front side of the first accommodating space, and when the inner air guide plate 2 and the outer air guide plate 3 are both in a closed state, the outer air guide plate 3 is located on the front side of the inner air guide plate 2.

[0060] According to the air conditioner indoor unit 100 of the embodiment of the present invention, the housing 1 has a first accommodating portion 11 and a second accommodating portion 12, the inner air guide plate 2 rotates in the first accommodating portion 11, and the outer air guide plate 3 rotates in the second accommodating portion 12, and when the inner air guide plate 2 and the outer air guide plate 3 are closed, the inner air guide plate 2 is located at the rear side of the outer air guide plate 3 and is shielded by the outer air guide plate 3. Thus, the size difference between the outer air guide plate 3 and the inner air guide plate 2 is reduced, and the aesthetics of the housing 1 of the air conditioner indoor unit 100 is ensured.

[0061] According to some embodiments of the present invention, Figure 3 and Fig.21 As shown, the outer air guide plate 3 is hollow inside and includes an outer panel rear panel 38 and an outer panel front panel 37 connected to each other. The outer panel rear panel 38 has an arc-shaped panel protruding toward the outer panel front panel 37, thereby forming an airflow Coanda silencer to increase the air supply distance of the air-conditioning indoor unit 100. At the same time, when the outer air guide plate 3 is opened, the wind from the air outlet 111 blows upward and then falls freely, forming a shower-like blowing, thereby improving the user's comfort.

[0062] Reference Figure 3 and Figure 8 The inner air guide plate 2 is hollow inside and includes an inner plate rear panel 22 and an inner plate front panel 21 connected to each other, and the inner plate front panel 21 is configured as an arc-shaped panel convex backward. Figure 3 As shown, the inner panel rear panel 22 and the inner panel front panel 21 are both constructed as arc-shaped panels protruding backwards, and the curvature of the inner panel rear panel 22 and the inner panel front panel 21 are different. The curvature of the inner panel rear panel 22 is greater than that of the inner panel front panel 21, which effectively ensures the strength of the inner air guide plate 2.

[0063] According to some embodiments of the present invention, the housing 1 includes an outer cover 13 and a left cover 131 and a right cover 132 respectively disposed on the left and right sides of the outer cover 13. Figure 5 As shown, the first accommodating portion 11 is disposed on the outer cover 13. By locating the first accommodating portion 11 on the front side of the outer cover 13, the installation space of the inner air guide plate 2 is effectively guaranteed, which facilitates the length of the inner air guide plate 2, reduces the size difference between the inner air guide plate 2 and the outer air guide plate 3, and improves the wind guiding effect. The second accommodating portion 12 is composed of the outer cover 13, the left cover 131 and the right cover 132, thereby ensuring the installation space of the outer air guide plate 3. In some optional embodiments, the housing 1 may further include a panel 15 and a base 16, and the panel 15 is located on one side of the outer cover 13 (for example, Figure 3 The base 16 is fixed to the lower end of the outer cover 13.

[0064] In some optional embodiments, when the inner air guide plate 2 is in the first closed position, the thickness of the upper end is greater than the thickness of the lower end. Figure 3 and Figure 8When the inner air guide plate 2 is closed, the thickness of the upper end of the inner air guide plate 2 is greater than the thickness of the lower end, which effectively ensures the strength of the inner air guide plate 2 and prevents the inner air guide plate 2 from breaking during rotation. It should be noted that when the inner air guide plate 2 is closed, the end facing the outside of the air conditioner indoor unit 100 and at a relatively high position is called the "upper end" (i.e., the pivot end), and the end facing the inside of the air conditioner indoor unit 100 and at a relatively low position is called the "lower end" (i.e., the free end).

[0065] In some optional embodiments, such as Figure 4 As shown, the first left side plate 113 and the second right side plate are provided with a first inner plate mounting column 1131 and a second inner plate mounting column 1141 opposite to each other, and the upper ends of the inner air guide plate 2 are respectively pivotally connected to the first inner plate mounting column 1131 and the second inner plate mounting column 1141. Optionally, as Figure 5 In the example shown, inner panel mounting holes may be respectively provided on the first left side panel 113 and the second left side panel, one end of the first inner panel mounting column 1131 and the second inner panel mounting column 1141 are inserted and fixed in the inner panel mounting holes while the other end is exposed and pivotally connected to the inner air guide plate 2, thereby effectively ensuring the reliability of the fixation of the inner air guide plate 2.

[0066] In some optional embodiments, such as Figure 3 As shown, the upper end of the inner air guide plate 2 is configured as an arc-shaped end, which effectively ensures that the inner air guide plate 2 can be pivotally fixed to the first accommodating portion 11, the extension length of the inner plate rear panel 22 is shorter than the extension length of the inner plate front panel 21, and the lower end of the inner plate front panel 21 is bent backward and covers the lower end of the inner plate rear panel 22, and the bending angle of the lower end of the inner plate front panel 21 meets 30-80 degrees, optionally about 60 degrees, but not limited thereto. Therefore, the inner plate rear panel 22 and the inner plate front panel 21 are conveniently formed in one piece, and the processing is simple.

[0067] According to some embodiments of the present invention, Figure 5 As shown, the housing 1 further includes an inner panel mounting plate 14, which is disposed on the outer cover 13, and the rear end of which is connected to the top of the first curved panel 112. The inner air guide plate 2 is fixed to the inner panel mounting plate 14, and a buckle extends downward from the front lower end of the inner panel mounting plate 14, and a buckle is provided at the top of the outer cover 13. The buckle cooperates with the buckle to mount the inner panel mounting plate 14 on the top of the outer cover 13. The front surface of the inner panel mounting plate 14 is inclined forward from bottom to top, defining the top area of ​​the first accommodating portion 11. As a result, the inner panel mounting plate 14 and the outer cover 13 can be independently injection molded, which makes it easy for the inner panel mounting plate 14 and the outer cover 13 to be demolded, and is convenient for manufacturing and assembly.

[0068] In some further embodiments of the present invention, Figure 5As shown, the front sides of the left cover 131 and the right cover 132 respectively have a left concave portion 1311 and a right concave portion 1321. After the left cover 131 and the right cover 132 are assembled to the outer cover 13, the left concave portion 1311, the right concave portion 1321 and the outer cover 13 jointly define a second accommodation space. The front sides of the left cover 131 and the right cover 132 also respectively have an outer plate mounting column 1312. The lower end of the outer air guide plate 3 is pivotally connected to the outer plate mounting column 1312. Figure 4-Figure 7 The left cover 131 and the right cover 132 are fixed to the left and right ends of the outer cover 13, and the lower end of the outer air guide plate 3 is connected to the outer plate mounting column 1312 and can be pivotally fixed to the second accommodating space, ensuring the installation space of the outer air guide plate 3 and facilitating installation.

[0069] In some further embodiments of the present invention, the outer plate mounting column 1312 has a fixing hole, and at least one end of the outer air deflector 3 has a movable latch assembly 31, that is, the outer air deflector 3 can be provided with a movable latch assembly 31 at one end, or both ends of the outer air deflector 3 are provided with movable latch assemblies 31. The movable latch assembly 31 is suitable for matching with the fixing hole and locking with the corresponding left cover 131 and / or right cover 132. Fig. 9 As shown, a movable latch assembly 31 is provided at the left end of the outer air guide plate 3. When the outer air guide plate 3 is installed, the movable latch assembly 31 is used in conjunction with the outer plate mounting column 1312 of the left cover 131, effectively ensuring the reliability of the fixation of the outer air guide plate 3 and facilitating the installation and removal of the outer air guide plate 3.

[0070] In some further embodiments of the present invention, Figure 2 As shown, the left and right ends of the outer air guide plate 3 both extend vertically out of the side walls 32. Fig.10 As shown, the side wall 32 of the corresponding side has a first fixing hole 321 and a second fixing hole 322, and the outer air guide plate 3 is further provided with a baffle 33 adjacent to the side wall 32, and the baffle 33 has a third fixing hole 331. Specifically, referring to Fig. 9 and Fig.10 The side wall 32 on the left side of the outer air guide plate 3 is provided with a first fixing hole 321 and a second fixing hole 322. The baffle plate 33 is located on the right side of the side wall 32 on the left side of the outer air guide plate 3. The side of the baffle plate 33 away from the outer air guide plate 3 is provided with a third fixing hole 331. Figure 9-11As shown, the movable latch assembly 31 is located between the side wall 32 and the baffle 33, and includes a first fixing column 311, a second fixing column 312, a latch column 313 and a spring 314. The first fixing column 311 is suitable for being inserted into the first fixing hole 321. The second fixing column 312 is parallel to the first fixing column 311 and connected through a connecting column. The second fixing column 312 is suitable for passing through the second fixing hole 322 and rotatably cooperating with the fixing hole. The latch column 313 is arranged on the upper part of the connecting column and extends away from the first fixing column 311. The latch column 313 is suitable for passing through the third fixing hole 331. The spring 314 is sleeved on the latch column 313. Thus, the reliability of the fixing of the movable latch assembly 31 is effectively guaranteed. The third fixing hole 331 on the baffle 33 plays a limiting role on the spring 314 of the movable latch assembly 31, and ensures that the movable latch assembly 31 is extended and retracted under the action of the spring 314.

[0071] During installation, the movable latch assembly 31 is installed between the left side wall 32 of the outer air guide plate 3 and the baffle 33, and the two ends of the spring 314 are stopped between the side wall 32 and the baffle 33. At this time, the free end of the latch column 313 passes through the third fixing hole 331, and the spring 314 pushes the first fixing column 311 and the second fixing column 312 into the first fixing hole 321 and the second fixing hole 322 respectively. The second fixing column 312 is suitable for cooperating with the fixing hole of the outer plate mounting column 1312.

[0072] In some optional embodiments, a movable latch assembly 31 is provided on one side of the outer air guide plate 3, and a third fixing column 34 is provided on the other side, and the third fixing column 34 is suitable for matching with the fixing hole on the corresponding side. Fig. 9 A movable latch assembly 31 is provided on the left side of the outer air guide plate 3, and a third fixing column 34 is provided on the right side. The third fixing column 34 cooperates with the fixing hole on the outer plate mounting column 1312 of the right cover 132 to facilitate the installation and removal of the outer air guide plate 3.

The sliding member 36 is coaxially connected to one end of the extension column 3631. The two extension pieces 3632 are arranged on both sides of the extension column 3631 in parallel with each other and extend from the sliding member 36 away from the air guide plate. In other words, the two extension pieces 3632 extend toward the interior of the air-conditioning indoor unit 100, and the distance between the two extension pieces 3632 is smaller than the diameter of the extension column 3631, so as to prevent the extension column 3631 from falling off and ensure the reliability of the fixation of the extension column 3631. The positioning groove 362 is defined between the extension piece 3632 and the sliding member 36.

[0080] Reference Fig.17 and Fig.19 When installing the outer air guide plate 3 and the outer drive device 4, the sliding member 36 moves toward the center of the outer air guide plate 3. When the sliding rod 361 is aligned with the hole on the side plate of the outer air guide plate 3, the sliding member 36 is pushed toward the connecting rod 42, so that the connecting rod 42 and the outer air guide plate 3 are hinged together. When disassembling, the sliding member 36 is pushed away from the connecting rod 42. Specifically, Fig.19 As shown, a positioning portion 363 is provided on the back side of the sliding member 36, and a positioning groove 362 is formed between the positioning portion 363 and one side of the sliding member 36, and limit strips 364 are provided on the left and right sides of the positioning groove 362, and positioning protrusions 351 are provided on the upper and lower edges of the sliding portion 35 on the rear side plate of the outer air guide plate 3. During installation, the positioning protrusion is located in the positioning groove 362, and the sliding member 36 slides left and right in the sliding portion 35 to realize the connection between the rotating arm 43 and the outer air guide plate 3.

[0081] In some optional embodiments, the sliding rod 361 and the extension column 3631 are metal parts, the sliding plate and the extension piece 3632 are plastic parts, and the sliding rod 361, the extension column 3631, the sliding plate and the extension piece 3632 are integrally injection molded. Thus, the strength of the sliding rod 361 and the extension column 3631 is ensured, and the installation is easy and the processing is simple.

[0082] In some optional embodiments, the external drive device 4 further includes a transmission assembly 45 , which is disposed between the motor 41 and the connecting rod 42 , and the transmission assembly 45 includes a plurality of gears meshing with each other to adjust the driving force output from the motor 41 to the connecting rod 42 .

[0083] For example, Figure 12-Figure 15 As shown, each outer drive device 4 further includes a connecting rod housing 44, a motor 41 is connected to a transmission assembly 45, the transmission assembly 45 is connected to a connecting rod 42, the connecting rod 42 is rotatably connected to a rotating arm 43, the connecting rod 42 and the rotating arm 43 are arranged in the connecting rod housing 44, and the other end of the rotating arm 43 extends out of the connecting rod housing 44 and is pivotally connected to the outer air guide plate 3. The motor 41 can also be directly connected to the connecting rod 42, but a larger motor driving force is required. By connecting the motor 41 to the transmission assembly 45, and the transmission assembly 45 to the connecting rod 42, the motor driving force can be amplified, thereby reducing the cost of the motor 41.

[0084] In some optional embodiments, referring to Fig.15 The transmission assembly 45 includes a first gear 451 and a second gear 452, the first gear 451 is sleeved on the motor shaft of the motor 41, the second gear 452 is connected to the rotating shaft of the connecting rod 42 to drive the connecting rod 42 to rotate, and the third gear 453 and the fourth gear 454 are meshed with each other, the third gear 453 is meshed with the first gear 451 and the fourth gear 454 is meshed with the second gear 452, which effectively ensures the transmission efficiency of the transmission assembly 45. Further optionally, the sizes of the outer diameters D1, D2, D3, and D4 of the first gear 451, the second gear 452, the third gear 453, and the fourth gear 454 meet: D4<D1<D2<D3. With such a configuration, it is easy to amplify the driving force of the external drive device 4 and reduce the cost of the motor 41. Of course, the present invention is not limited to this. The number of gears and the outer diameter ratio adopted in the traditional assembly 45 can also be determined according to the specific design.

[0085] In some optional embodiments, at least one of the inner panel rear panel 22 and the inner panel front panel 21 is provided with a plurality of parallel inner panel patterns 23 extending in the left-right direction.
