Further, referring to fig. 1 to 13, for the air conditioning indoor unit of the present application, the driving assembly 3 includes a driving motor 31, a transmission member 32 and a connecting rod 33, the driving motor 31 is fixed on the base, the transmission member 32 is connected to an output shaft of the driving motor 31, the transmission member 32 is provided with a first tooth portion 321, one end of the connecting rod 33 is hinged to the transmission member 32, the other end of the connecting rod 33 passes through the auxiliary groove 223 to be hinged to the first air deflector 21, the inner side surface of the second air deflector 22 is further provided with a connecting portion 221, the second air deflector 22 is connected to the base through the connecting portion 221, and the connecting portion 221 is provided with a second tooth portion 2211 engaged with the first tooth portion 321.
Based on the above structure, before use, the second air deflector 22 and the first air deflector 21 are vertically overlapped to block the air outlet 11, so as to prevent dust from entering the indoor unit of the air conditioner from the air outlet 11, when the air conditioner is used, the driving motor 31 is started, the rotation of the output shaft of the driving motor 31 drives the transmission member 32 to rotate together, the first tooth portion 321 on the transmission member 32 rotates together with the rotation of the transmission member 32, the rotation of the first tooth portion 321 drives the second tooth portion 2211 engaged with the first tooth portion 321 to rotate continuously, and the first air deflector 21 and the second air deflector 22 rotate around the output shaft of the driving motor 31 under the rotation of the second tooth portion 2211 and open the air outlet 11; further, the rotation of the transmission member 32 can also drive the position of the connecting rod 33 to change, because the two ends of the connecting rod 33 are respectively hinged to the transmission member 32 and the first air deflector 21, along with the continuous rotation of the transmission member 32, the connecting rod 33 extends forwards to drive the first air deflector 21 to move along the width direction of the second air deflector 22, at the moment, the second air deflector 22 and the first air deflector 21 are in an unfolded state, the unfolding and turning of the first air deflector 21 obviously improves the width of the whole air deflector assembly 2, and the air outlet effect can be effectively strengthened. So this air conditioning indoor set opens and close air outlet 11 and adjust the air-out direction through setting up double-deck aviation baffle, first aviation baffle 21 and the coincidence of second aviation baffle 22 when air outlet 11 is closed, first aviation baffle 21 also can follow the continuous expansion of second aviation baffle 22's width and make aviation baffle subassembly 2's effective width obtain promoting and then strengthen the wind-guiding effect when air outlet 11 is opened, its structural design is ingenious, the result of use is outstanding.
Further, referring to fig. 4-7, in order to control the sliding range of the first air deflector 21 and ensure that the first air deflector 21 moves close to the second air deflector 22 rather than moves to other positions due to the movement of the connecting rod 33, the bottom surface of the second air deflector 22 is provided with a guide rail 222, the first air deflector 21 is provided with a sliding groove 2111 matched with the guide rail 222, specifically, the guide rail 222 includes a vertical plate 2221 connected with the first air deflector 21 and a horizontal plate 2222 connected with the vertical plate 2221, wherein the width of the vertical plate 2221 is smaller than that of the horizontal plate 2222, the cross section of the whole guide rail 222 is in an inverted "T" shape, the width of the sliding groove 2111 is smaller than that of the horizontal plate 2222 and is not smaller than that of the vertical plate 2221, when the assembly is completed, the vertical plate 2221 of the guide rail 222 is inserted into the sliding groove 2111, the horizontal plate 2222 of the guide rail 222 is exposed out of the sliding groove 2111 and located below the first air deflector 21121, so as to prevent the first air deflector 21 from moving in other directions, the horizontal plate 2222 is ensured that the first air deflector 21 always moves along the sliding groove 2221.
Furthermore, the rear end of the sliding groove 2111 is expanded to form a rectangular installation hole 2112, in order to ensure the normal installation of the guide rail 222, the width of the installation hole 2112 is not less than that of the transverse plate 2222 of the guide rail 222, so the cross section of the installation hole 2112 and the sliding groove 2111 is in a "T" shape in this embodiment, the transverse plate 2222 of the guide rail 222 passes through the installation hole 2112 to reach the lower part of the first air deflector 21 during assembly, and the vertical plate 2221 enters the sliding groove 2111 through the installation hole 2112.
Referring to fig. 4 to 7, for the second air guiding plate 22 and the first air guiding plate 21 in the embodiment, in order to ensure that the first air guiding plate 21 slides reasonably and stably close to the second air guiding plate 22, it is difficult to ensure that all areas of the first air guiding plate 21 are effectively limited under the condition of only providing a single guide rail 222, so to avoid the above situation, a plurality of guide rails 222 are provided, each guide rail 222 is sequentially provided along the long side of the second air guiding plate 22, meanwhile, due to the increase of the number of the guide rails 222, the number of the corresponding sliding grooves 2111 on the first air guiding plate 21 also needs to be increased, and actually, when a plurality of guide rails 222 are provided, the number of the sliding grooves 2111 is consistent with the guide rails 222, and the sliding grooves 2111 are in one-to-one correspondence with the guide rails 222.
It should be noted that, most of the components such as the first air deflector 21 and the second air deflector 22 are made of soft plastics, and the rigidity is poor, the structures such as the guide rail 222 and the driving member are all symmetrical structures, that is, the driving motor 31, the transmission member 32, and the connecting rod 33 in the present application are provided with two sets, the two sets of driving motor 31, the transmission member 32, and the connecting rod 33 are respectively provided on the left and right sides of the second air deflector 22, and the two sets are symmetrically arranged with respect to the center line of the second air deflector 22, in fact, if the similar structures are asymmetrically arranged, a situation that one side has rotated or moved to a specified position and the other part has not reached the specified position occurs during use may occur, and this situation may further cause the structures such as the second air deflector 22 and the first air deflector 21 to deform, which affects the normal use of the air conditioning indoor unit, and in order to avoid the above situations, it is also necessary to pay attention to the symmetry problem when the same structure is provided with a plurality of structures.
Further, referring to fig. 12 and 13, the edge of the connecting portion 221 is provided with a stop plate 2212, and the stop plate 2212 can abut against the transmission member 32 when the first tooth portion 321 and the second tooth portion 2211 are not engaged. It can be found that, as the rotating link 33 of the transmission member 32 continuously pushes the first air guiding plate 21 to move forward, in actual use, due to design errors and other factors, when the rotation angle of the second air guiding plate 22 reaches the maximum, the first air guiding plate 21 does not completely extend, and if the second tooth portion 2211 is selected to be added, the second air guiding plate 22 is further caused to rotate again, in this embodiment, the stop plate 2212 is selected to be disposed on the connecting portion 221, when the meshing rotation between the first tooth portion 321 and the second tooth portion 2211 reaches the end point, the stop plate 2212 abuts against the transmission member 32, at this time, the connecting portion 221 is continuously operated to drive the driving motor 31 to rotate the transmission member 32, and only the link 33 is continuously moved, and the connecting portion 221 is not influenced by the transmission member 32 any more because the second tooth portion 2211 is no longer meshed with the first tooth portion 321, the connecting portion 221 remains still, so that the first air guiding plate 21 is continuously pushed to move after the rotation of the second air guiding plate 22 reaches the designated angle. When the air outlet 11 needs to be closed, the driving motor 31 only needs to be rotated reversely to drive the first tooth portion 321 to be meshed with the second tooth portion 2211 again, so that the second air deflector 22 and the first air deflector 21 can be ensured to move reversely under the driving of the driving member to close the air outlet 11 again.
