[0054] Reference below Figure 1-Figure 20 The air conditioner indoor unit 100 and the air conditioner according to the embodiment of the present invention are described.

[0055] like Figure 1 and Figure 8 As shown, according to an embodiment of the present invention, the air-conditioning indoor unit 100 includes: a surface frame 10, a switch door 20, a connecting member 30 and a driving assembly 40.

[0056] Specifically, if Figure 2 As shown, the face frame 10 may be provided with an air outlet 110, whereby the heat exchange airflow in the air conditioner indoor unit 100 may be blown out from the air outlet 110 to achieve the cooling or heating function of the air conditioner. Of course, the air conditioner may also have a humidification function, and the humidified airflow may be blown out from the air outlet 110, thereby increasing the humidity of the indoor air and the user's comfort.

[0057] The switch door 20 is movably disposed on the face frame 10 to open or close the air outlet 110. Thus, when the air conditioner is working, the switch door 20 can be controlled to open the air outlet 110, so that the heat exchange airflow of the air conditioner indoor unit 100 is blown out from the air outlet 110. When the air conditioner stops working, the switch door 20 can be controlled to close the air outlet 110, thereby preventing dust or impurities from entering the air conditioner indoor unit 100 from the air outlet 110, thereby ensuring the normal operation of the air conditioner indoor unit 100.

[0058] like Figure 3 , Figure 6 and Figure 7As shown, the face frame 10 may be provided with a through hole 120 spaced apart from the air outlet 110, and the connecting member 30 includes a first plate 310 and a second plate 320, wherein the first plate 310 is provided inside the face frame 10, the second plate 320 is fixed on the first plate 310, and the outer end of the second plate 320 extends out of the through hole 120 and is connected to the switch door 20. Thus, by providing the through hole 120 on the face frame 10 and driving the switch door 20 to move through the through hole 120 by the second plate 320, the structure of the air conditioner indoor unit 100 can be made compact. Moreover, through the above arrangement, the movement amplitude of the switch door 20 when opening or closing the air outlet 110 can also be shortened, so that the switch door 20 can be closer to the face frame 10 during the movement, so as to improve the operation stability of the switch door 20.

[0059] The driving assembly 40 is arranged inside the face frame 10 and is connected to the first plate 310 to drive the second plate 320 to reciprocate along the extension track of the through hole 120. Thus, by providing the driving assembly 40, the movement of the connecting member 30 driven by the driving assembly 40 can be used to drive the movement of the door 20. Moreover, the driving assembly 40 can be arranged inside the face frame 10, thereby preventing the driving assembly 40 from being damaged by collision, and improving the compactness of the structure and the aesthetic appearance of the air conditioner indoor unit 100.

[0060] According to the air conditioner indoor unit 100 of the embodiment of the present invention, by providing a through hole 120 on the face frame 10, and connecting the drive assembly 40 and the switch door 20 by using the first plate 310 and the second plate 320 that are fixedly connected, the connection between the switch door 20 and the drive assembly 40 is facilitated, and the stability and reliability of the movement of the switch door 20 are improved. In addition, the movement amplitude of the switch door 20 is reduced, so that the switch door 20 is closer to the face frame 10 when moving, and the compactness of the structure of the air conditioner indoor unit 100 is improved. In addition, the drive assembly 40 can drive the movement of the first plate 310 and the second plate 320, and then can drive the opening and closing of the switch door 20, thereby conveniently and reliably controlling the opening and closing of the air outlet 110.

[0061] According to some embodiments of the present invention, Figure 7 and Fig.14 As shown, the first plate 310 can be a plastic part, thereby facilitating the processing and manufacturing of the first plate 310, thereby reducing the production cost of the first plate 310. Moreover, the overall weight of the first plate 310 can be reduced. The second plate 320 can be a sheet metal part. Since the second plate 320 is connected to the switch door 20, and the switch door 20 is driven to move by the second plate 320, the structural strength of the second plate 320 can be improved by setting the second plate 320 as a sheet metal part, avoiding the second plate 320 from being damaged by excessive force, and improving the stability and reliability of the operation of the switch door 20.

[0062] In some embodiments of the present invention, Fig.16 and Fig. 20 As shown, the second plate 320 may include: a horizontally extending first portion 321 and a second portion 322. The first portion 321 may be fixed to the first plate 310, for example, the first portion 321 may be fixedly connected to the first plate 310 using screws, thereby improving the firmness and reliability of the assembly between the first plate 310 and the second plate 320.

[0063] like Fig. 20 As shown, the second part 322 can extend in the up-down direction, and the second part 322 can be fixed on the first part 321. It should be noted that the second plate body 320 can be an integrally formed part, and the second plate body 320 can also be configured as a combination of the first part 321 and the second part 322. The second part 322 can be fitted with the rear surface of the switch door 20. Thus, the assembly between the second plate body 320 and the switch door 20 is facilitated, and the second part 322 can also form a surface contact with the rear surface of the switch door 20, thereby improving the firmness and reliability of the cooperation between the switch door 20 and the second plate body 320.

[0064] According to some embodiments of the present invention, Fig. 20 As shown, the first part 321 and the second part 322 may be provided with an assembly hole 323 at the bend, and the switch door 20 may be provided with an assembly protrusion 210, which may cooperate with the assembly hole 323 to enable the connector 30 and the switch door 20 to move synchronously. Thus, the assembly and fixation between the second plate 320 and the switch door 20 is facilitated. Moreover, the assembly protrusion 210 and the assembly hole 323 have a simple structure and are easy to process and manufacture, which not only facilitates assembly, but also reduces the production cost of the air conditioner indoor unit 100.

[0065] According to some embodiments of the present invention, Fig.14 As shown, the driving assembly 40 may include: a motor 410, a gear 420 and a rack 430. The gear 420 may be connected to the motor 410 to be driven to rotate by the motor 410. The rack 430 may be meshed with the gear 420 to be driven to reciprocate by the gear 420, and the rack 430 may be connected to the first plate 310 to drive the connecting member 30 to move. It can be understood that the transmission of the gear 420 and the rack 430 can improve the stability and reliability of the operation of the connecting member 30.

[0066] like Fig.14 and Fig.18As shown, the motor 410 can be connected to the gear 420. For example, the gear 420 can be connected to the output shaft of the motor 410, and the gear 420 can mesh with the rack 430. When the motor 410 runs forward, the motor 410 can drive the gear 420 to rotate forward, and the gear 420 can drive the rack 430 to move forward when it rotates, and then the rack 430 can drive the connecting member 30 to move, and the switch door 20 moves with the connecting member 30 to open the air outlet 110; when the motor 410 runs reversely, the motor 410 can drive the gear 420 to rotate in the reverse direction, and the gear 420 can drive the rack 430 to move in the reverse direction, and can drive the switch door 20 to close the air outlet 110 through the connecting member 30.

[0067] In some embodiments of the present invention, Fig.14 As shown, the driving assembly 40 may further include a box body 440, and the gear 420 and the rack 430 are respectively arranged in the box body 440. Thus, the box body 440 can protect the gear 420 and the rack 430, and prevent the gear 420 and the rack 430 from being damaged by collision. Moreover, the box body 440 can also prevent debris from entering between the gear teeth of the gear 420 and the rack 430 to affect the transmission between the gear 420 and the rack 430. The rack 430 may be provided with an assembly part 431 extending out of the box body 440, and the assembly part 431 may be connected to the first plate body 310. Thus, when the rack 430 moves, the connecting member 30 can be driven to move synchronously through the assembly part 431.

[0068] According to some embodiments of the present invention, Fig.14 As shown, the box body 440 may be provided with a first track channel 441, and the assembly part 431 may be movably matched with the first track channel 441. Thus, the movement track of the assembly part 431 may be limited by the first track channel 441, thereby improving the stability and stability of the movement of the rack 430 and the connecting member 30, thereby making the movement of the door 20 more stable and improving the accuracy of the movement track of the door 20.

[0069] In some embodiments of the present invention, two spaced apart assembly parts 431 may be provided on the rack 430, and the first track channels 441 corresponding to the two assembly parts 431 are spaced apart. Fig.14 As shown, two assembly parts 431 can be arranged at intervals at both ends of the length direction of the rack 430, and the box body 440 can be correspondingly provided with first track channels 441 adapted to the two assembly parts 431, thereby limiting the movement of the assembly parts 431 in the corresponding first track channels 441, thereby further improving the accuracy and stability of the movement of the door 20. Optionally, the first track channel 441 can be formed as an arc track to reduce the friction resistance between the assembly parts 431 and the inner peripheral wall of the first track channel 441, and improve the smoothness of the movement of the rack 430.

[0070] According to some embodiments of the present invention, the rack 430 may be provided with a second track channel 432, and the box body 440 may be provided with a positioning column 442 that moves with the second track channel 432. Fig.14 As shown, the rack 430 may be provided with a second track channel 432 that runs through in the thickness direction, and the second track channel 432 may extend in the length direction of the rack 430. A positioning column 442 that runs through the second track channel 432 may be provided in the box body 440. Thus, when the rack 430 moves in the box body 440, the movement track of the rack 430 can be limited by the cooperation between the positioning column 442 and the inner peripheral wall of the second track channel 432, thereby further improving the accuracy and stability of the movement of the door 20. The second track channel 432 may be formed as an arc-shaped channel, thereby reducing the friction between the inner peripheral wall of the second track channel 432 and the positioning column 442, and improving the smoothness of the movement of the rack 430.

[0071] In some embodiments of the present invention, Fig.14 and Fig.18 As shown, the outer peripheral wall of the positioning column 442 may be provided with a shaft sleeve 443, and the shaft sleeve 443 may be provided with an upper limit plate 4431 and a lower limit plate 4432 spaced apart from each other in the vertical direction. The upper limit plate 4431 and the lower limit plate 4432 may be located at the upper and lower ends of the rack 430, respectively. It should be noted that the shaft sleeve 443 may be one, and the shaft sleeve 443 has the upper limit plate 4431 and the lower limit plate 4432 spaced apart from each other in the vertical direction. Of course, the shaft sleeve 443 may also be two, such as Fig.18 As shown, the sleeve 443 may include an upper sleeve 443a and a lower sleeve 443b, and the upper sleeve 443a and the lower sleeve 443b may be sleeved on the positioning column 442, and the rack 430 may be clamped between the upper sleeve 443a and the lower sleeve 443b. Thus, the sleeve 443 may be used to keep the rack 430 and the top wall and the bottom wall of the box body 440 spaced apart, so as to avoid friction between the rack 430 and the top wall or the bottom wall of the box body 440, thereby improving the smoothness of the operation of the rack 430. Optionally, the sleeve 443 may be an elastic rubber part to facilitate the processing and assembly of the sleeve 443. Of course, the sleeve 443 may also be a metal part to improve the structural strength of the sleeve 443, and to improve the reliability of the matching between the sleeve 443 and the positioning column 442 and the rack 430.

[0072] According to some embodiments of the present invention, Fig.14 and Fig.16As shown, the first plate 310 can be connected to the rack 430, and the second plate 320 can extend out of the through hole 120 and be connected to the switch door 20. The first plate 310 is connected to the second plate 320, and the second plate 320 is sandwiched between the box body 440 and the first plate 310, thereby improving the structural strength and operational reliability of the connector 30.

[0073] In some embodiments of the present invention, the upper and lower ends of the air outlet 110 may be provided with through holes 120, and the upper and lower ends of the switch door 20 may be connected to the connecting member 30 respectively. Fig.19 As shown, the upper and lower ends of the switch door 20 may be connected to connecting members 30, respectively. It should be noted that the connecting member 30 at the upper end of the switch door 20 and the connecting member 30 at the lower end of the switch door 20 may move synchronously to drive the switch door 20 to open or close the air outlet 110. By connecting the connecting members 30 at the upper and lower ends of the switch door 20, respectively, the stability and reliability of the movement of the switch door 20 may be improved. Moreover, by arranging the connecting members 30 at the upper and lower ends of the switch door 20, the internal space of the air conditioner indoor unit 100 occupied by the connecting members 30 may be reduced, and the utilization rate of the internal space of the air conditioner indoor unit 100 may be improved.

[0074] According to some embodiments of the present invention, Figure 1 and Figure 2 As shown, the front surface of the face frame 10 may include a first appearance surface S1 and a second appearance surface S2, the first appearance surface S1 may be located in front of the second appearance surface S2, and the air outlet 110 may be provided on the second appearance surface S2. It should be noted that the "first appearance surface S1" mentioned here may be understood as the appearance surface formed by the switch door 20 and the face frame 10 when the switch door 20 closes the air outlet 110. The "second appearance surface S2" may be understood as the appearance surface exposed by the face frame 10 when the switch door 20 opens the air outlet 110. By providing the air outlet 110 on the second appearance surface S2, when the air conditioner indoor unit 100 stops running, the switch door 20 may close the air outlet 110 and shield the second appearance surface S2, thereby improving the appearance of the air conditioner indoor unit 100.

[0075] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the height of the switch door 20 can be the same as the height of the first appearance surface S1. When the switch door 20 closes the air outlet 110, the front surface of the portion of the switch door 20 that contacts the first appearance surface S1 can be flush with the first appearance surface S1. Therefore, when the switch door 20 closes the air outlet 110, the switch door 20 and the face frame 10 can be well connected and transitioned, avoiding an abrupt transition between the switch door 20 and the face frame 10 that affects the appearance of the air conditioner indoor unit 100.

[0076] The air conditioner according to the embodiment of the present invention includes the air conditioner indoor unit 100 according to the above embodiment of the present invention.
