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

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

[0057] like Figures 1-8 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 (as shown in FIG. Figure 4 (As shown), the second accommodating space is located in front of the first accommodating space. The second accommodating portion 12 has an outer plate mounting post 1312 with a fixing hole. The inner air deflector 2 is pivotally mounted within the first accommodating space. The outer air deflector 3 is pivotally mounted within the second accommodating space. At least one end of the outer air deflector 3 has a movable latch assembly 31 adapted to engage with the fixing hole and lock with the housing 1 to pivotally connect the outer air deflector 3 to the lower edge of the air outlet 111.

[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 on the front side of the housing 1, and the second accommodating space is located in front of the first accommodating space. The inner air guide plate 2 is rotatably disposed in the first accommodating portion 11 to control the opening and closing of the air outlet 111, and 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. It should be noted here that in the description of this specification, when the user faces the air conditioner indoor unit 100, the direction toward the user is referred to as "front", and conversely, the direction away from the user is referred to as "rear".

[0060] like Figure 9 and Figure 10 As shown, the outer panel mounting column 1312 has a fixing hole, and at least one end of the outer air deflector 3 has a movable latch assembly 31. In other words, the outer air deflector 3 can be provided with a movable latch assembly 31 at one end, or at both ends of the outer air deflector 3. 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. Figure 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 to effectively ensure the firmness of the fixation of the outer air guide plate 3 and facilitate the installation and disassembly of the outer air guide plate 3.

[0061] According to the air conditioner indoor unit 100 of the embodiment of the present invention, the second accommodating portion 12 has an outer panel mounting post 1312 with a fixing hole. At least one end of the outer air deflector 3 has a movable latch assembly 31. The movable latch assembly 31 is adapted to engage with the fixing hole and lock with the housing 1 to pivotally connect the outer air deflector 3 to the lower edge of the air outlet 11. This effectively ensures the secure fixation of the outer air deflector 3 and facilitates installation and removal of the outer air deflector 3.

[0062] 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, and as shown Figure 10 As shown, the side wall 32 on 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 Figure 9 and Figure 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 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 33 away from the outer air guide plate 3 is provided with a third fixing hole 331. Figures 9-11 As shown, the movable latch assembly 31 is located between the side wall 32 and the baffle 33 and includes a first fixing post 311, a second fixing post 312, a latch post 313, and a spring 314. The first fixing post 311 is adapted to be inserted into the first fixing hole 321. The second fixing post 312 is parallel to the first fixing post 311 and connected to it via a connecting post. The second fixing post 312 is adapted to pass through the second fixing hole 322 and engage with the fixing hole. The latch post 313 is located above the connecting post and extends away from the first fixing post 311. The latch post 313 is adapted to pass through the third fixing hole 331. The spring 314 is sleeved on the latch post 313. This effectively ensures the secure fixation of the movable latch assembly 31. The third fixing hole 331 on the baffle 33 limits the spring 314 of the movable latch assembly 31, ensuring that the movable latch assembly 31 can extend and retract under the force of the spring 314.

[0063] 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.

[0064] In some optional embodiments, a movable latch assembly 31 is provided on one side of the outer air deflector 3, and a third fixing column 34 is provided on the other side. The third fixing column 34 is adapted to cooperate with the fixing hole on the corresponding side. Figure 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 disassembly of the outer air guide plate 3.

[0065] When the lock body 31 is unlocked, the lock body 31 is unlocked, and the lock body 31 is unlocked, and the lock body 31 is unlocked, and the lock body 31 is unlocked, and the lock body 31 is unlocked, and the lock body 31 is unlocked.

[0066] 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 provided on the left and right sides of the outer cover 13. Figure 5 As shown, the first accommodating portion 11 is provided 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 lengthening the length of the inner air guide plate 2, reducing the size difference between the inner air guide plate 2 and the outer air guide plate 3, and improving 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. 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.

[0067] like Figure 5 As shown, according to some embodiments of the present invention, 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 accommodating space. The outer plate mounting posts 1312 have two posts respectively provided on the front sides of the left cover 131 and the right cover 132. Furthermore, the lower end of the outer air deflector 3 is pivotally connected to the outer plate mounting posts 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 easy installation.

[0068] In some further embodiments of the present invention, the thickness of the upper end of the inner air guide plate 2 when in the closed state is greater than the thickness of the lower end thereof. Figure 3 and Figure 8 When the inner air deflector 2 is closed, the thickness of the upper end of the inner air deflector 2 is greater than the thickness of the lower end, effectively ensuring the strength of the inner air deflector 2 and preventing breakage during rotation. It should be noted that the end of the inner air deflector 2 facing the outside of the air conditioner indoor unit 100 and positioned relatively high when closed is referred to as the "upper end" (i.e., the pivot end), and the end facing the inside of the air conditioner indoor unit 100 and positioned relatively low is referred to as the "lower end" (i.e., the free end).

[0069] like Figure 4 As shown, the first accommodating portion 11 includes a first curved panel 112, a first left side panel 113, and a first right side panel 114. The first curved panel 112 is located on one side of the housing 1 and gradually tilts backward from bottom to top, ensuring that the arc shape of the first curved panel 112 is consistent with the inner air deflector 2. This improves the fit between the inner air deflector 2 and the first curved panel 112 when the inner air deflector 2 is closed and reduces the gap between the inner air deflector 2 and the outer cover 13. The first left side panel 113 and the first right side panel are located on the left and right sides of the first curved panel 112, respectively, and the three define a first accommodating space. The inner air deflector 2 is pivotally positioned within the first accommodating space.

[0070] In some further embodiments of the present invention, Figure 4 As shown, the first left panel 113 and the second right panel are provided with a first inner panel mounting column 1131 and a second inner panel mounting column 1141 opposite to each other, and both sides of the upper end of the inner air guide plate 2 are pivotally connected to the first inner panel mounting column 1131 and the second inner panel mounting column 1141 respectively. Figure 5 In the example shown, inner plate mounting holes can be respectively provided on the first left side panel 113 and the second left side panel, one end of the first inner plate mounting column 1131 and the second inner plate mounting column 1141 are inserted and fixed in the inner plate mounting holes while the other end is exposed and pivotally connected to the inner air guide plate 2, effectively ensuring the reliability of the inner air guide plate 2 being fixed.

[0071] In some optional embodiments, the outer panel rear panel 38 is provided with a plurality of parallel outer panel patterns 39 extending in the left-right direction, which ensures the strength of the outer air guide plate 3 while reducing the weight of the outer air guide plate 3, thereby achieving lightweight outer air guide plate 3. Figure 3As shown, after the air-conditioning indoor unit 100 is installed, the distance between the upper end of the mounting portion of the outer air guide plate 3 and the wall is greater than the distance between the lower end of the mounting portion of the outer air guide plate 3 and the wall. This makes it easier for the air-conditioning indoor unit 100 to blow the wind from the air outlet 111 away from the wall when the air-conditioning indoor unit 100 is working, thereby reducing the wind flow through the gap between the mounting portion of the outer air guide plate 3 and the outer cover 13, thereby reducing condensation on the front side of the outer air guide plate 3.

[0072] In some specific embodiments of the present invention, Figure 3 and Figure 8 The inner air guide plate 2 is hollow inside and includes an inner panel rear panel 22 and an inner panel front panel 21 connected to each other. The inner panel rear panel 22 and the inner panel front panel 21 are both constructed as arc-shaped panels protruding backward, and the curvature of the inner panel rear panel 22 and the inner panel front panel 21 is 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.

[0073] In some optional embodiments, such as Figure 3 As shown, the upper end of the inner air deflector 2 is configured as an arcuate end, effectively ensuring that the inner air deflector 2 can be pivotally fixed to the first accommodating portion 11. The extended length of the inner panel rear panel 22 is shorter than the extended length of the inner panel front panel 21, and the lower end of the inner panel front panel 21 is bent backward and covers the lower end of the inner panel rear panel 22. The bending angle of the lower end of the inner panel front panel 21 is within a range of 30-80 degrees, optionally approximately 60 degrees, but not limited thereto. This facilitates the integral molding of the inner panel rear panel 22 and the inner panel front panel 21, simplifying processing.

[0074] 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. Figure 3 and Figure 8 In the illustrated example, the rear surface of the inner panel rear panel 22 is provided with an inner panel pattern 23, and the front surface of the inner panel front panel 21 is provided with an inner panel pattern 23. This facilitates airflow guidance and reduces the weight of the inner air guide plate 2, achieving component weight reduction. Of course, the inner panel pattern 23 may also be provided on only the inner panel rear panel 22 or the inner panel front panel 21.

[0075] According to some embodiments of the present invention, Figure 5As shown, the housing 1 also includes an inner panel mounting plate 14, which is mounted on the outer cover 13 and has a rear end 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. A clip extends downward from the front lower end of the inner panel mounting plate 14. The top of the outer cover 13 has a clip slot, and the clip and the slot cooperate 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 tilts 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, making it easy to remove the inner panel mounting plate 14 and the outer cover 13 from the mold and convenient to manufacture and assemble.

[0076] like Figure 12 and Figure 13 As shown, according to some embodiments of the present invention, the air conditioner indoor unit 100 further includes two external drive devices 4, which are respectively provided on the left and right sides of the outer cover 13 to drive the outer air guide plate 3 to rotate between the second closed position and the second open position. In some specific examples, such as Figure 14 and Figure 15 As shown, each external drive device 4 includes a motor 41, a connecting rod 42 and a rotating arm 43. The motor 41 is installed on the side of the outer cover 13. The connecting rod 42 is connected to the motor 41 and is driven to rotate by the motor 41. One end of the rotating arm 43 is pivotally connected to the connecting rod 42, and the other end is pivotally connected to the outer air guide plate 3.

[0077] In some further embodiments of the present invention, referring to Figure 13 and combined Figure 16-19 , the inner surface of the outer air guide plate 3 has a sliding portion 35, such as Figure 13 As shown, sliding portions 35 are provided on both the left and right ends of the inner surface of the outer air deflector 3. Sliding members 36 are slidably provided on the sliding portions 35. The sliding members 36 have sliding rods 361. The other end of the rotating arm 43 has an insertion hole 431. The sliding rod 361 is rotatably inserted into the insertion hole 431, effectively ensuring the flexibility of the sliding rod 361 and the rotating arm 43. The rotating arm 43 also plays a supporting role when the outer air deflector 3 is opened.

[0078] In some specific embodiments, Figures 17-20 As shown, the sliding member 36 is plate-shaped, but not limited thereto. The sliding member 36 has a positioning groove 362 on the surface of one side facing the outer air guide plate 3, and the sliding portion 35 has a positioning protrusion 351. Figure 17 The sliding portion 35 is provided with two positioning protrusions 351, which are opposite to each other up and down. The positioning protrusions 351 slide in the positioning grooves 362 to realize the sliding of the sliding member 36 on the sliding portion 35. Thus, the sliding member 36 drives the outer air guide plate 3 to rotate, and the processing is simple.

[0079] like Figure 19As shown, the side of the slider 36 facing away from the air guide plate has a positioning portion 363, that is, the side of the slider 36 facing the interior of the air conditioner indoor unit 100 is provided with the positioning portion 363. The extension axis of the positioning portion 363 is parallel to the slider 36, and the positioning groove 362 is defined by the positioning portion 363 and the slider 36. This effectively ensures the secure fixation of the slider 36 while saving materials and reducing costs.

[0080] Furthermore, the side of the sliding member 36 away from the air guide plate has two limit bars 364, the two limit bars 364 are perpendicular to the extension axis of the positioning portion 363, and the two limit bars 364 are arranged at both ends of the positioning groove 362 to limit the position of the positioning protrusion 351 in the positioning groove 362.

[0081] In some optional embodiments, such as Figure 19 As shown, the positioning portion 363 includes an extension column 3631 and two extension pieces 3632. The cross-section of the extension column 3631 is generally circular. One end of the extension column 3631 is flush with the sliding member 36, that is, the left end of the extension column 3631 is flush with the left end of the sliding member 36. 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, which prevents the extension column 3631 from falling off and ensures 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.

[0082] Reference Figure 17 and Figure 19 When installing the outer air deflector 3 and the outer drive device 4, the sliding member 36 moves toward the center of the outer air deflector 3. When the sliding rod 361 is aligned with the hole on the side plate of the outer air deflector 3, the sliding member 36 is pushed toward the connecting rod 42, so that the connecting rod 42 and the outer air deflector 3 are hinged together. When disassembling, the sliding member 36 is pushed away from the connecting rod 42. Specifically, Figure 19 As shown, a positioning portion 363 is provided on the back 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 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 connection between the rotating arm 43 and the outer air guide plate 3 is realized by sliding the sliding member 36 left and right in the sliding portion 35.

[0083] In some optional embodiments, the sliding rod 361 and the extension column 3631 are metal parts, and the sliding plate and the extension piece 3632 are plastic parts. The sliding rod 361, the extension column 3631, the sliding plate and the extension piece 3632 are integrally injection molded. This ensures the strength of the sliding rod 361 and the extension column 3631, and is easy to install and process.

[0084] 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 . 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 .

[0085] For example, Figure 12-15 As shown, each outer drive device 4 further includes a connecting rod housing 44, a motor 41 connected to a transmission assembly 45, which is connected to a connecting rod 42, which is rotationally connected to a rotating arm 43. The connecting rod 42 and the rotating arm 43 are disposed within 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 deflector 3. The motor 41 can also be directly connected to the connecting rod 42, but this requires a greater motor driving force. 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.

[0086] In some optional embodiments, referring to Figure 15 The transmission assembly 45 includes a first gear 451 and a second gear 452. The first gear 451 is mounted 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. 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, effectively ensuring the transmission efficiency of the transmission assembly 45. Further optionally, 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 satisfy the following: D4 < D1 < D2 < D3. Such an arrangement can easily 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 used in the traditional assembly 45 can also be determined according to the specific design.

[0087] According to some embodiments of the present invention, Figure 3 and Figure 21As 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 is constructed to be inclined toward the outer panel front panel 37 in the direction from the pivot end to the free end, that is, it has an arc-shaped portion recessed toward the outer panel front panel 37, thereby forming an airflow Coanda silencer and improving 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.

[0088] According to an embodiment of the present invention, the air conditioner indoor unit 100 is as follows: Figure 22 As shown, when the air conditioner indoor unit 100 is cooling, the inner air guide plate 2 swings to the top and the outer air guide plate 3 swings to supply air. Figure 23 As shown, when the air conditioner indoor unit 100 is in heating mode, the outer air guide plate 3 swings to the uppermost position and the inner air guide plate 2 swings to supply air. Thus, the user can experience a shower-like air blower regardless of whether the air conditioner indoor unit 100 is in cooling or heating mode, thereby improving the user's comfort.
