[0070] In some optional embodiments of the present invention, Figure 6 and Figure 7 As shown, the switch door 2 is provided with a connecting plate 5 extending in the first direction, and the rack 42 is provided on the connecting plate 5. As a result, it is convenient to achieve connection between the rack 42 and the switch door 2, which is conducive to improving the reliability of the switch door 2 in the process of moving up and down, with a simple structure, reliable movement, and smooth operation. For example, there are two racks 42, and the two racks 42 are respectively provided at the two ends of the connecting plate 5 along the second direction, and the teeth on the two racks 42 extend in directions away from each other, and there are two drive assemblies 3, and the two drive assemblies 3 are spaced apart along the second direction and correspond one to one with the two racks 42. Optionally, the rack 42 and the connecting plate 5 are an integrally formed part.

[0071] In some optional embodiments of the present invention, Figure 3 As shown, the connecting plate 5 is detachably connected to the switch door 2. It is understandable that during the long-term operation of the switch door 2, it is convenient to replace and repair the rack 42. For example, the connecting plate 5 and the switch door 2 can be connected by clamping, riveting or threading.

[0072] In some optional embodiments of the present invention, Fig.14 As shown, the air conditioner indoor unit 100 further includes a push rod 43, one end of which is rotatably connected to the connecting plate 5, and the other end of which is rotatably connected to the switch door 2.

[0073] For example, Fig.18As shown, a connection portion is provided at the bottom of the switch door 2, a pivot hole is provided on the connection portion, a pivot shaft for cooperating with the pivot hole is provided on the other end of the push rod 43, and the other end of the push rod 43 is tilted upward, and the push rod 43 can rotate slightly during the movement of the switch door 2 in the first direction. Optionally, a torsion spring is provided between the push rod 43 and the connecting plate 5, so as to ensure the reliability of the push rod 43 and further prevent the switch door 2 from getting stuck during the sliding process in the first direction.

[0074] In some optional embodiments of the present invention, referring to Figure 3 As shown, the switch door 2 is movably arranged on the outside of the housing 1; or; refer to Fig.13 As shown, the air conditioner indoor unit 100 further includes a mounting bracket 6, which is disposed in the housing 1, and the switch door 2 is movably disposed on the mounting bracket 6 and is located between the mounting bracket 6 and the air outlet 111. Thus, it is convenient to realize the movement of the switch door 2 in the first direction to open or close the plurality of air outlets 111.

[0075] Alternatively, if Fig.14 As shown, the air conditioner indoor unit 100 further includes a motor mounting seat 31, a first accommodation space is provided on the motor mounting seat 31, a second accommodation space is provided on the rear surface of the mounting bracket 6 and is recessed forward, the first accommodation space and the second accommodation space define an accommodation chamber for accommodating the drive assembly 3 and the gear 41, the drive motor is accommodated in the first accommodation space, and the gear 41 is accommodated in the second accommodation space. Thus, the drive assembly 3 and the gear 41 can be enclosed, which is conducive to improving the reliability of the operation of the drive assembly 3.

[0076] In some optional embodiments of the present invention, referring to Figure 6 As shown, a guide groove 91 extending in the first direction is provided on the outer surface of the housing 1 or the mounting bracket 6, and a guide rail 51 slidably matched with the guide groove 91 is provided on the rear surface of the connecting plate 5. Thus, the guide groove 91 on the outer surface of the housing 1 or the mounting bracket 6 can guide the movement of the guide rail 51 in the first direction, that is, the guide groove 91 on the outer surface of the housing 1 or the mounting bracket 6 can guide the movement of the opening and closing door 2 in the first direction, so that the movement of the opening and closing door 2 can be more stable and smooth.

[0077] For example, Figure 4 and Figure 6 As shown, the switch door 2 is movably arranged on the outer side of the panel 11, the outer surface of the panel 11 is provided with a guide groove 91 extending along the first direction, and the rear surface of the connecting plate 5 is provided with a guide rail 51 that slidably cooperates with the guide groove 91;

[0078] For example, refer to Fig.14As shown, the mounting bracket 6 is arranged in the casing 1, the switch door 2 is movably arranged on the mounting bracket 6 and is located between the mounting bracket 6 and the air outlet 111, the mounting bracket 6 is provided with a guide groove 91 extending along the first direction, and the rear surface of the connecting plate 5 is provided with a guide rail 51 that slides with the guide groove 91.

[0079] In some examples of the present invention, Figure 6 As shown, a fixing plate 9 extending along a first direction is provided on the outer surface of the housing 1 or the mounting bracket 6, and a guide groove 91 is provided on the fixing plate 9. Thus, the guide groove 91 and the fixing plate 9 can be integrally formed first, and then the fixing plate 9 is connected to the mounting bracket 6, thereby reducing the difficulty of manufacturing the mounting bracket 6.

[0080] Optionally, the fixing plate 9 and the outer surface of the casing 1 or the mounting bracket 6 are detachably connected. It is understandable that the guide groove 91 is easily damaged during long-term use. By making the fixing plate 9 and the outer surface of the casing 1 or the mounting bracket 6 detachably connected, when the guide groove 91 is damaged, the fixing plate 9 can be directly replaced without replacing the casing 1 or the mounting bracket 6, which is beneficial to reducing the maintenance cost of the air-conditioning indoor unit 100.

[0081] Optionally, the fixing plate 9 is a metal piece, thereby improving the deformation problem of the guide groove 91 and improving the reliability of the matching between the guide groove 91 and the guide rail 51 on the connecting plate 5 .

[0082] In some optional embodiments of the present invention, the fixing plate 9 is an aluminum extrusion molded part, which is helpful to further improve the deformation problem of the guide groove 91 and improve the reliability of the matching between the guide groove 91 and the guide rail 51 on the connecting plate 5 .

[0083] In some optional embodiments of the present invention, Figure 6 As shown, the minimum width of the guide groove 91 is d1, the maximum thickness of the guide rail 51 is d2, and d1 and d2 satisfy: 0.1mm≤d1-d2≤1mm. Therefore, during the movement of the switch door 2 along the first direction, the guide rail 51 has a movement space of 0.1mm-1mm in the guide groove 91, which is conducive to preventing the switch door 2 from getting stuck during the movement due to the position error between the guide groove 91 and the guide rail 51. Among them, d1-d2 can take any value between 0.1mm-1mm. For example, the value of d1-d2 can be 0.15mm, 0.25mm, 0.35mm, 0.45mm, 0.55mm, 0.65mm, 0.75mm, 0.85mm, 0.95mm, etc.

[0084] In some optional embodiments of the present invention, Figure 5 and Fig. 20As shown, the opposite side walls of the mounting bracket 6 in the second direction or the opposite outer side walls of the housing 1 in the second direction are respectively formed with sliding grooves 61 that are recessed in the direction away from each other, and the two ends of the switch door 2 in the second direction are respectively provided with sliding shafts 23 that cooperate with the sliding grooves 61. Thus, the sliding grooves 61 on the mounting bracket 6 or the housing 1 can guide the movement of the sliding shaft 23 in the first direction, that is, the sliding grooves 61 on the mounting bracket 6 or the housing 1 can guide the movement of the switch door 2 in the first direction, so that the movement of the switch door 2 can be more stable and smooth.

[0085] For example, Figure 4 and Figure 5 As shown, the switch door 2 is movably arranged on the outer side of the housing 1, the panel 11 is provided with a guide groove 91 extending in the first direction, and the rear surface of the connecting plate 5 is provided with a guide rail 51 slidably matched with the guide groove 91. At the same time, the opposite outer side walls of the panel 11 in the second direction are respectively formed with sliding grooves 61 concave in the direction away from each other, and the two ends of the switch door 2 in the second direction are respectively provided with sliding shafts 23 matched with the sliding grooves 61.

[0086] For example, Fig. 20 As shown, the mounting bracket 6 is arranged in the casing 1, the switch door 2 is movably arranged on the mounting bracket 6 and is located between the mounting bracket 6 and the air outlet 111, the mounting bracket 6 is provided with a guide groove 91 extending along the first direction, and the rear surface of the connecting plate 5 is provided with a guide rail 51 that slides with the guide groove 91. At the same time, sliding grooves 61 that are recessed in directions away from each other are respectively formed on the opposite side walls of the mounting bracket 6 in the second direction, and sliding shafts 23 that cooperate with the sliding grooves 61 are respectively provided at both ends of the switch door 2 in the second direction.

[0087] In some optional embodiments of the present invention, Fig.11 As shown, each sliding shaft 23 is provided with a roller 24. Fig.13 As shown, the roller 24 is sleeved on the outer peripheral wall of the sliding wheel. Therefore, through the rolling cooperation between the roller 24 and the sliding groove 61, it is helpful to reduce the resistance between the switch door 2 and the housing 1 or the mounting bracket 6, reduce noise, reduce power consumption and improve the user experience.

[0088] In some embodiments of the present invention, reference Fig.14As shown, the switch door 2 includes a shielding portion 21 and an air guide 22. When the switch door 2 is in a closed state where multiple air outlets 111 are closed and the shielding portion 21 is located at the multiple air outlets 111, when the switch door 2 is in a fully opened state where multiple air outlets 111 are fully opened, the air guide 22 is directly opposite to at least part of the multiple air outlets 111. Among them, "the air guide 22 is directly opposite to at least part of the multiple air outlets 111" can be understood as the air guide 22 is directly opposite to several of the multiple air outlets 111, or the air guide 22 is directly opposite to all the air outlets 111. Therefore, it is beneficial to reduce the travel of the switch door 2 in the first direction, reduce the power consumption of the switch door 2, and facilitate fast startup and improve the user experience.

[0089] For example, Fig.13 As shown, six air outlets 111 are provided on the casing 1, and four air guide outlets 22 are provided on the switch door 2. When the switch door 2 closes the six air outlets 111 in a closed state, the shielding portion 21 is located at the six air outlets 111. When the switch door 2 fully opens the six air outlets 111 in a fully open state, the four air guide outlets 22 are directly opposite to the four air outlets 111 located at the bottom among the six air outlets 111.

[0090] In some embodiments of the present invention, reference Fig.13 and Fig.14 As shown, multiple air outlets 111 are divided into multiple groups of air outlet groups along a first direction, and each group of air outlet groups includes at least one air outlet 111; the shielding portion 21 includes multiple shielding areas 21a, and the multiple shielding areas 21a are spaced apart along the first direction, and a group of air guide ports is provided between each adjacent two shielding areas 21a, and each group of air guide ports group includes at least one air guide port 22, and the number of air guide ports 22 in each group of air guide ports is the same as the number of air outlets 111 in each group of air outlet groups. Of course, the present invention is not limited to this, and the number of air guide ports 22 in each group of air guide ports may also be different from the number of air outlets 111 in each group of air outlet groups. For example, the number of air guide ports 22 in each group of air guide ports may be less than the number of air outlets 111 in each group of air outlet groups.

[0091] Reference Fig.16 As shown, in the closed state, multiple shielding areas 21a correspond to multiple groups of air outlet groups one by one and each shielding area 21a is used to shield the corresponding air outlet group. It can be understood that in the closed state, the part between each two adjacent groups of air outlet groups is directly opposite to the air guide port group;

[0092] Reference Fig.17As shown, in the fully open state, one of the two groups of air outlet groups located on the outermost sides is staggered with the switch door 2 in the front-to-back direction and the remaining air outlet groups correspond to the air guide port groups one-to-one. In the corresponding air guide port groups and air outlet groups, the multiple air guide ports 22 of each air guide port group are directly opposite to the multiple air outlets 111 in the air outlet group. For example, "one of the two groups of air outlet groups located on the outermost sides" can be understood as the air outlet group located at the top or the air outlet group located at the bottom. As a result, it is beneficial to further reduce the travel of the switch door 2 in the first direction, reduce the power consumption of the switch door 2 movement, and facilitate fast startup and improve the user experience.

[0093] In some examples, such as Fig.13 As shown, the housing 1 is provided with six air outlets 111, and the six air outlets 111 are divided into three groups of air outlet groups along the vertical direction, and each group of air outlet groups includes two air outlets 111; there are three shielding areas 21a, and the three shielding areas 21a are spaced apart in the vertical direction, and a group of air guide ports is provided between each two adjacent shielding areas 21a, that is, the switch door 2 is provided with two groups of air guide ports, and each group of air guide ports includes two air guide ports 22, such as Fig.15 and Fig.16 As shown, in the closed state, the three shielding areas 21a correspond to the three groups of air outlets one by one and each shielding area 21a is used to shield the corresponding air outlet group, such as Fig.17 As shown, in the fully open state, the topmost group of air outlet groups is staggered with the switch door 2 in the front-to-back direction and the remaining two air outlet groups correspond one-to-one with the two air guide port groups. In the corresponding air guide port groups and air outlet groups, the two air guide ports 22 of each air guide port group are directly opposite to the two air outlets 111 in the air outlet group, and the central axis of each air guide port 22 coincides with the corresponding air outlet 111.

[0094] In some optional embodiments of the present invention, Fig.13 As shown, each air outlet group includes a plurality of air outlets 111 spaced apart along the second direction, and each air guide group includes a plurality of air guides 22 spaced apart along the second direction. Thus, the air outlets 111 can be arranged in multiple rows and columns, which is further conducive to achieving large-area air supply of the air conditioner indoor unit 100, improving the user's comfort, and improving the aesthetics of the appearance of the air conditioner indoor unit 100. For example, Figure 2 As shown, six air outlets 111 are provided on the housing 1, and the six air outlets 111 are arranged in three rows and two columns.

[0095] In some optional embodiments of the present invention, Fig.13As shown, the shape of the air guide port 22 is the same as the shape of the air outlet 111, and the flow area of ​​the air guide port 22 is not less than the flow area of ​​the air outlet 111. This is conducive to ensuring the air volume of the air conditioner indoor unit 100, thereby ensuring the energy efficiency of the air conditioner indoor unit 100. For example, the shape of the air guide port 22 and the shape of the air outlet 111 are both formed in a circular shape, and the flow area of ​​the air guide port 22 is not less than the flow area of ​​the air outlet 111.

[0096] In some embodiments, Fig.18 As shown, the mounting bracket 6 is provided with a plurality of avoidance openings 62, and the plurality of avoidance openings 62 are arranged one-to-one with the plurality of air outlets 111, and the shape of each avoidance opening 62 is the same as the shape of the air outlet 111, and the flow area of ​​the avoidance opening 62 is not less than the flow area of ​​the air outlet 111. This is conducive to ensuring the air volume of the air conditioner indoor unit 100, thereby facilitating ensuring the energy efficiency of the air conditioner indoor unit 100.
