[0038] Figure 1 This is a schematic structural diagram of a first driving device 300 and a second driving device 500 mounted on a sliding plate 200 according to an embodiment of the present invention. Figure 1 As shown, and refer to Figures 2 to 6 This utility model provides an indoor unit for an air conditioner, including a housing 100, a sliding plate 200, and a first driving device 300. An air outlet is provided on the housing 100. The sliding plate 200 is slidably disposed at the air outlet and configured to open or close the air outlet. A first insertion hole 400 with its opening facing downwards is provided on the sliding plate 200. The output portion of the first driving device 300 includes a first insert 350 for insertion into the first insertion hole 400, and the output portion of the first driving device 300 is configured to drive the sliding plate 200 to slide.

[0039] The air outlet is used to blow out heat exchange airflow to change the indoor temperature. The heat exchange airflow can be either heating or cooling airflow. When installing the slide plate 200 with an openable and closable air outlet, the first insert 350 of the first drive device 300 is inserted into the first insertion hole 400 with the opening facing downwards on the slide plate 200, which can realize the installation of the slide plate 200. The assembly is tight and stable, improving installation efficiency and saving installation costs.

[0040] In some embodiments of this utility model, such as Figure 4 As shown, the first socket 400 is rectangular.

[0041] In some embodiments of this utility model, such as Figure 4 As shown, a guide rib 600 is provided on the peripheral wall of the first insertion hole 400. The guide rib 600 forms a tapered structure in the direction from bottom to top to guide the insertion of the first insert 350.

[0042] The guide rib 600 is designed to guide the first insert 350 into the first socket 400 and to facilitate the installation of the first insert 350 in the first socket 400.

[0043] In some embodiments of this utility model, such as Figure 2 As shown, the first insert 350 is an insert plate, with its upper end smaller than its lower end. Guide ribs 600 are provided on both sides of the insert plate.

[0044] The insertion plate having a smaller upper end than lower end facilitates insertion of the insertion plate into the first socket 400, and the guide ribs 600 located on both sides of the insertion plate facilitate centered insertion of the insertion plate into the first socket 400.

[0045] Furthermore, in some embodiments of this utility model, such as Figure 4 As shown, each side of the insertion plate is provided with at least two guide ribs 600. The four guide ribs 600 enable the insertion plate to smoothly enter the first insertion hole 400.

[0046] In some embodiments of this utility model, such as Figure 4 As shown, the guide ribs 600 on both sides of the insertion plate have different thicknesses, with the guide rib 600 on the side closer to the air outlet having a greater thickness than the guide rib 600 on the side farther from the air outlet.

[0047] In some embodiments of this utility model, such as Figure 4 As shown, the guide ribs 600 on both sides of the insertion plate have different widths, with the guide rib 600 on the side closer to the air outlet having a wider width than the guide rib 600 on the side farther from the air outlet.

[0048] In some embodiments of this utility model, such as Figure 2As shown, there are at least two first inserts 350 and at least two first sockets 400, with each first insert 350 inserted into one first socket 400. Having two first inserts 350 and two first sockets 400 improves the stability of the installation between the skateboard 200 and the first drive device 300.

[0049] In some embodiments of this utility model, such as Figure 2 As shown, the output section of the first drive device 300 also includes a first connecting plate 351, and at least two first inserts 350 are disposed at intervals on the same edge of the first connecting plate 351.

[0050] In some embodiments of this utility model, such as Figure 5 As shown, an indentation groove 354 is provided on one side of the connection between the first connecting plate 351 and the first insert 350, so that a reinforcing protrusion is formed on the other side of the connection between the first connecting plate 351 and the first insert 350.

[0051] The reinforced protrusion can enhance the connection strength between the first connecting plate 351 and the two first inserts 350, and prevent the connection position between the first connecting plate 351 and the two first inserts 350 from breaking or deforming under stress, which would affect the sliding of the slide plate 200.

[0052] In some embodiments of this utility model, such as Figure 5 As shown, the output section of the first drive device 300 further includes a third connecting plate 352 and a fourth connecting plate 353. One end of the first connecting plate 351 is connected to one end of the third connecting plate 352, and the first connecting plate 351 and the third connecting plate 352 are at a 90-degree angle, i.e., they form an L-shape. The other end of the fourth connecting plate 353 is connected to the third connecting plate 352, and the fourth connecting plate 353 is at a 90-degree angle to the third connecting plate 352, i.e., they form an L-shape. The first connecting plate 351 and the fourth connecting plate 353 are located on the same side of the third connecting plate 352. The first connecting plate 351, the fourth connecting plate 353, and the third connecting plate 352 are integrally formed.

[0053] In some embodiments of this utility model, such as Figure 5 As shown, the third connecting plate 352 is provided with reinforcing protrusions, which can improve the strength of the third connecting plate 352.

[0054] In some embodiments of this utility model, such as Figure 5As shown, the first driving device 300 includes a driving housing 310, a rack 320, a gear 330, and a driving motor 340. The rack 320 is slidably disposed within the driving housing 310, and a fourth connecting plate 353 is connected to the rack 320. The gear 330 is disposed within the driving housing 310 and meshes with the rack 320. The driving motor 340 is disposed on the driving housing 310 and located on the upper side of the driving housing 310, and the gear 330 is mounted on the output shaft of the driving motor 340.

[0055] The drive motor 340 rotates, which drives the gear 330 mounted on the output shaft of the drive motor 340 to rotate. The gear 330 drives the rack 320 to slide, and the rack 320 then drives the fourth connecting plate to slide. The fourth connecting plate is connected to the first connecting plate through the third connecting plate, which drives the slide plate to slide.

[0056] In some embodiments of this utility model, such as Figure 3 As shown, the indoor unit of the air conditioner also includes a second drive device 500, which is disposed below the first drive device 300. A second insertion hole 700 with its opening facing downwards is provided on the slide plate 200, and the output portion of the second drive device 500 has a second insert 512 that is inserted upwards into the second insertion hole 700.

[0057] When installing the slide plate 200 with an openable air outlet, first insert the second insert 512 of the second drive device 500 into the second socket 700 with the opening facing downward on the slide plate 200. Then lift the slide plate 200. While preventing the second insert 512 from coming out of the second socket 700, insert the first insert 350 of the first drive device 300 into the first socket 400 with the opening facing downward on the slide plate 200 to achieve a more stable installation of the slide plate 200.

[0058] In some embodiments of this utility model, such as Figure 2 As shown, the output of the first drive device 300 is connected to the slide plate 200 via a fixing device. The fixing device is located between the first connecting plate 351 and the slide plate 200, and between two adjacent first insertion holes 400. After the second insert 512 of the second drive device 500 is inserted into the downward-facing second insertion hole 700 on the slide plate 200, and the first insert 350 of the first drive device 300 is inserted into the downward-facing first insertion hole 400 on the slide plate 200, the fixing device further ensures that the slide plate 200 is stably mounted on the first drive device 300.

[0059] In some embodiments of this utility model, such as Figure 4 and Figure 5As shown, the fixing device includes screws. The first connecting plate 351 has mounting holes 355, and the sliding plate 200 has screw posts 210 positioned between the two first insertion holes 400. Each screw post has a downward-facing screw hole. The screw passes through the mounting hole 355 from bottom to top and is screwed into the screw hole.

[0060] In some embodiments of the present invention, the output of the second drive device 500 is configured to allow the slide plate 200 to undergo downward elongation deformation due to thermal expansion and contraction.

[0061] The slide plate 200 is located at the air outlet. Regardless of whether the air outlet blows out a hot or cold airflow, the deformation of the slide plate 200 during thermal expansion and contraction will be greater than the deformation of the housing 100. The output part of the second drive device 500 can prevent the slide plate 200 from being squeezed when the slide plate 200 deforms relative to the housing 100, especially when it stretches downward.

[0062] Furthermore, in some embodiments of this utility model, such as Figure 3 As shown, the output section of the second drive device 500 also includes a second connecting plate 511, a second insert 512 is disposed on the second connecting plate 511, the second connecting plate 511 is disposed on the lower side of the second socket 700, and the distance between the lower end face of the second socket 700 and the second connecting plate 511 is greater than or equal to 2mm.

[0063] After the first drive device 300 and the second drive device 500 are installed in place, and the fixing device secures the first drive device 300 to the slide plate 200, a distance of 2mm or more between the lower end face of the second insertion hole 700 and the second connecting plate 511 can provide a manufacturing tolerance gap and prevent compression of the slide plate 200 due to the different deformations of the slide plate 200 and the housing 100 during thermal expansion and contraction. For example, during thermal expansion, the elongation of the slide plate 200 in the length direction is greater than that of the housing 100 in the length direction. In this case, a distance of 2mm or more between the lower end face of the second insertion hole 700 and the second connecting plate 511 can prevent the slide plate 200 from being squeezed and deformed. During thermal contraction, the shortening of the slide plate 200 in the length direction is greater than that of the housing 100. In this case, since the second insert 512 can move up and down within the second insertion hole 700, the slide plate 200 can also be prevented from being squeezed and deformed.

[0064] In some embodiments of this utility model, the output section of the second driving device 500 has the same structure as the output section of the first driving device 300, but may be the same or different in size. The first socket 400 and the second socket 700 have the same structure, but may be the same or different in size.

[0065] In some embodiments of this utility model, such as Figure 6As shown, the air outlet includes a first air outlet 101 and a second air outlet 102. The first air outlet 101 is disposed on one side wall of the housing 100, and the second air outlet 102 is disposed on the other side wall of the housing 100. Both the first air outlet 101 and the second air outlet 102 extend vertically. The sliding plate includes a first sliding plate 200 and a second sliding plate 800, which are respectively disposed at the first air outlet 101 and the second air outlet 102. The first driving device and the second driving device are both connected to the first sliding plate 200.

[0066] In some embodiments of this utility model, such as Figure 6 As shown, an air duct is provided inside the housing 100. The air duct has a main air duct section 130, and a first air duct section 110 and a second air duct section 120 connected to the front end of the main air duct section 130. The first air duct section 110 is connected to the first air outlet 101, and the second air duct section 120 is connected to the second air outlet 102. The main air duct section 130 includes a first air duct wall 131 and a second air duct wall 132 disposed opposite to each other. A cross-flow impeller 140 is disposed inside the housing 100. The first air duct wall 131 is a volute tongue surface, and the second air duct wall 132 is a volute shell surface. The volute tongue surface has a volute tongue portion that cooperates with the cross-flow impeller 140. The volute tongue portion, the volute shell surface, and the cross-flow impeller 140 cooperate to work together. The diversion device is located at the front end of the main air duct section 130. The diversion device is configured to guide and divert the airflow from the main air duct section 130 so that part of the airflow flows to the first air duct section 110 and the rest flows to the second air duct section 120. The diversion device includes a first diversion plate 910, a second diversion plate 920 and a third diversion plate 930 arranged at intervals.

[0067] The cross-flow fan 140 rotates, creating airflow between the volute tongue and the volute surface. This airflow passes through the first air duct section 110 and the second air duct section 120, and exits from the first air outlet 101 corresponding to the first air outlet 110 and the second air outlet 102 corresponding to the second air outlet 120. The first air outlet 101 and the second air outlet 102 are respectively located on two opposite side walls of the housing 100, increasing the air delivery range and enabling ultra-wide-angle whole-house air delivery. When the airflow generated by the cross-flow fan 140 flows between the volute tongue and the volute surface, it is mainly concentrated on one side of the volute surface. By adjusting the airflow direction through the diversion device at the front end of the main air duct section 130, the flow rate of the air entering the first air duct section 110 and the second air duct section 120 can be adjusted, and the resistance of the airflow entering the first air duct section 110 and the second air duct section 120 can be reduced. Finally, the amount of airflow flowing out of the first air outlet 101 and the second air outlet 102 is adjusted accordingly, so that the total amount of airflow flowing out of the first air outlet 101 and the second air outlet 102 is equal or not much different, so that the air outlet of the indoor unit of the air conditioner is balanced from left to right, ensuring the horizontal air supply effect, and also ensuring the uniform temperature of the indoor space.
