[0041] The utility model provides an air conditioner.

[0042] See also Figures 1 to 8 In one embodiment of the utility model, the air conditioner comprises:

[0043] The housing 10 is provided with an air outlet 11;

[0044] The door body 20 can be opened and closed to cover the air outlet 11;

[0045] An air guide 30 is rotatably disposed at the air outlet 11 and is disposed corresponding to the inner side of the door body 20; and

[0046] A driving member (not shown) is connected to the door body 20 and the air guide member 30 through an incomplete gear mechanism;

[0047] From the initial state of the air conditioner, the driving member can alternately drive the door body 20 to open the air outlet 11 and drive the air guide member 30 to swing.

[0048] In the technical solution of the utility model, the transmission is transmitted between the driving member and the door body 20 and the air guide member 30 through an incomplete gear mechanism, so that the same driving member can drive the door body 20 to open and close the air outlet 11, and can also drive the air guide member 30 to swing, and the opening and closing of the door body 20 and the swinging of the air guide member 30 are performed alternately without interference. Among them, the driving member can be a motor, but is not limited to a motor.

[0049] When the air conditioner is in standby mode, the relative positions of the door body 20 and the air guide member 30, and the matching state of the incomplete gear mechanism are as follows: Figure 3 and Figure 4 As shown, specifically, the door body 20 covers the air outlet 11 , and the air guide member 30 is accommodated on the inner side of the door body 20 .

[0050] When the air conditioner is turned on, the driving member is started, which enables the incomplete gear mechanism to be connected to the door body 20 and disconnect the transmission connection with the air guide member 30. As a result, the driving member will only drive the door body 20 to open the air outlet 11, and the air guide member 30 will not be driven. After the air outlet 11 is fully opened, the incomplete gear mechanism disconnects the transmission connection with the door body 20. At this time, the relative positions of the door body 20 and the air guide member 30, as well as the matching state of the incomplete gear mechanism are shown in FIG. Figure 5 and Figure 6 As shown, the air guide member 30 is still in the initial position in the accommodated state at this time, and the initial position is also the extreme position of the air guide member 30 on one side.

[0051] The driving member continues to operate, and the incomplete gear mechanism can be connected to the air guide member 30, thereby driving the air guide member 30 to swing, and the door body 20 can also maintain the position of opening the air outlet 11. Figure 7 and Figure 8 In the state shown, the air guide member 30 has reached the limit position on the other side.

[0052] At this time, the driving member rotates forward and reverse alternately within a preset range, and can drive the air guide member 30 to swing back and forth between the two aforementioned extreme positions, thereby realizing the air sweeping function of the air conditioner, which is beneficial to expanding the air supply range of the air conditioner.

[0053] When the air conditioner is turned off, the driving member will rotate in the opposite direction, and the cooperation between the incomplete gear mechanism and the door body 20 and the air guide member 30 will be reversed according to the above process, that is, the driving member will drive the air guide member 30 to return to the previous accommodation state, and at the same time, the door body 20 is still maintained in the state of opening the air outlet 11. Thereafter, the air guide member 30 will be maintained in the accommodation state, and the driving member will drive the door body 20 to cover the air outlet 11. In particular, the air guide member 30 is inclined relative to the penetrating direction of the air outlet 11 in the accommodation state to avoid the movement of the door body 20, so that the door body 20 and the air guide member 30 of the air conditioner can be more compactly distributed.

[0054] It should be particularly noted that the air conditioner of the present invention may be an integrated air conditioner, a split air conditioner, or may only include an indoor unit of a split air conditioner.

[0055] In one embodiment, the air conditioner is configured as a cabinet unit.

[0056] In one embodiment, the air conditioner is configured as a split-type air conditioner including a cabinet, and the casing 10 is disposed in the cabinet.

[0057] In one embodiment, the door body 20 opens and closes the air outlet 11 along the width direction of the air outlet 11, the air guide 30 extends along the length direction of the air outlet, and the rotation axis of the air guide 30 is parallel to the length direction of the air outlet 11. In this way, the swing direction of the air guide 30 and the direction in which the door body 20 opens and closes the air outlet 11 are both roughly in the width direction of the air outlet 11, which facilitates the cooperation between the incomplete gear mechanism and the air guide 30 and the door body 20. Of course, in other embodiments, the movement directions of the door body 20 and the air guide 30 may also be different, and the incomplete gear mechanism is connected to the door body 20 or the air guide 30 through other components.

[0058] In one embodiment, if Figures 3 to 8 As shown, the incomplete gear mechanism includes a driving gear 100, the driving member is drivingly connected to the driving gear 100, the door body 20 is provided with a first connecting tooth portion 21, the air guide member 30 is provided with a second connecting tooth portion 31, and the driving gear 100 is alternately transmission-connected to the first connecting tooth portion 21 and the second connecting tooth portion 31.

[0059] In one embodiment, if Figures 3 to 9 As shown, the driving gear 100 is provided with two driving teeth 110 distributed along the axial direction, and the two driving teeth 110 are configured as incomplete teeth with different central angles, and the driving gear 100 can be alternately connected to the first connecting teeth 21 and the second connecting teeth 31 through the two driving teeth 110. For the convenience of the following description, the two driving teeth 110 are referred to as the first driving teeth 111 and the second driving teeth 112, respectively, the first driving teeth 111 and the first connecting teeth 21 are a pair of teeth that can be connected in transmission, and the second driving teeth 112 and the second connecting teeth 31 are a pair of teeth that can be connected in transmission, and the transmission connection of the two pairs of teeth is alternately performed, so that the driving member can alternately drive the door body 20 and the air guide member 30 through the driving gear 100. Since the central angles of the first driving tooth portion 111 and the second driving tooth portion 112 are different, the driving gear 100 can be connected to the door body 20 and the swing blade at different rotation angles, thereby enabling the driving gear 100 to meet the different requirements of the door body 20 and the swing blade for the movement amplitude.

[0060] In one embodiment, if Figure 9As shown, the central angle of the driving tooth part 110 for drivingly connecting the first connecting tooth part 21 is greater than that of the driving tooth part 110 for drivingly connecting the second connecting tooth part 31. That is, the central angle of the first driving tooth part 111 is greater than that of the second driving tooth part 112. In this way, the rotation angle of the driving gear 100 drivingly connected to the door body 20 is greater than the rotation angle of the driving connection to the air deflector 30, which can meet the large-scale opening and closing of the air outlet 11 by the door body 20 and the small-scale swinging of the air deflector 30.

[0061] In one embodiment, as Figures 3 to 9 shown, the driving gear 100 is further provided with two first locking arc parts 120. The two ends of one first locking arc part 120 are respectively butted against the two ends of one driving tooth part 110. When the driving gear 100 is drivingly connected to one of the door body 20 and the air deflector 30 through the corresponding driving tooth part 110, it also locks the other of the door body 20 and the air deflector 30 through the corresponding first locking arc part 120.

[0062] For the convenience of subsequent description, the two first locking arc parts 120 are respectively called the first sub-locking arc part 121 and the second sub-locking arc part 122. The first sub-locking arc part 121 is used to lock the door body 20, and the second sub-locking arc part 122 is used to lock the air deflector 30. The two ends of the first sub-locking arc part 121 are respectively connected to the two ends of the first driving tooth part 111, and the two ends of the second sub-locking arc part 122 are respectively connected to the two ends of the second driving tooth part 112. That is, the first sub-locking arc part 121 and the first driving tooth part 111 are connected to form a complete circle, and the second sub-locking arc part 122 and the second driving tooth part 112 are connected to form a complete circle. In this way, after the first driving tooth part 111 disconnects the driving connection with the first connecting tooth part 21, the door body 20 can be immediately locked by the first sub-locking arc part 121 until the driving gear 100 is driven to re-drivingly connect to the first connecting tooth part 21 through the first driving tooth part 111; similarly, after the second driving tooth part 112 disconnects the driving connection with the second connecting tooth part 31, the air deflector 30 can also be immediately locked by the second sub-locking arc part 122 until the driving gear 100 is driven to re-drivingly connect to the second connecting tooth part 31 through the second driving tooth part 112.

[0063] Specifically, when the driving gear 100 drives the door body 20 to move through the transmission connection of the first driving tooth part 111 and the first connecting tooth part 21, it also locks the air guiding member 30 through the second sub-locking arc part 122, so that the second connecting tooth part 31 can be stably in a preset position and wait for the second driving tooth part 112 to be in transmission connection with it; similarly, when the driving gear 100 is in transmission connection through the second driving tooth part 112 and the second connecting tooth part 31, it also locks the door body 20 through the first locking arc part 120, so that the first connecting tooth part 21 can be stably in a preset position and wait for the first driving tooth part 111 to be in transmission connection with it.

[0064] In one embodiment, as Figures 3 to 8 shown, the incomplete gear mechanism further includes a transmission gear 200, and the driving gear 100 is in transmission connection with the first connecting tooth part 21 through the transmission gear 200. In this way, the driving gear 100 does not need to directly mesh with the first connecting tooth part 21 of the door body 20 and the second connecting tooth part 31 of the air guiding member 30 at the same time. The second driving tooth part 112 can be indirectly in transmission connection with the first connecting tooth part 21 through the transmission gear 200, reducing the structural design difficulty and spatial layout difficulty of the driving gear 100. Of course, in other embodiments, it may also be that by reasonably designing the structure of the driving gear 100, for example, differentiating the outer diameters of the first driving tooth part 111 and the second driving tooth part 112, making the outer diameter of the first driving tooth part 111 larger, and directly meshing the first driving tooth part 111 with the first connecting tooth part 21.

[0065] In one embodiment, as Figures 3 to 8 and Figure 10 shown, the transmission gear 200 is provided with two transmission tooth parts 210 distributed along the axial direction and having different outer diameters, and the two transmission tooth parts 210 are respectively used to mesh with the driving gear 100 and the first connecting tooth part 21. In this way, the transmission gear 200 can mesh with the driving gear 100 and the first connecting tooth part 21 through the transmission tooth parts 210 with different outer diameters. While the transmission gear 200 plays a role in transmitting motion, it can also flexibly change the transmission ratio between the driving gear 100 and the first connecting tooth part 21 by changing the outer diameters of the two transmission tooth parts 210 to ensure that the rotation of the driving gear 100 can meet the movement amplitude of opening and closing the air outlet 11 when opening and closing the door. Of course, in other embodiments, it may also be that different sides of the same transmission tooth part 210 of the transmission gear 200 are respectively meshed with the driving gear 100 and the first connecting tooth part 21, or there are other transmission structures between the transmission gear 200 and the driving gear 100 or between the transmission gear 200 and the first connecting tooth part 21.

[0066] For the convenience of the following description, the two transmission tooth portions 210 are respectively referred to as the first transmission tooth portion 211 and the second transmission tooth portion 212. The first transmission tooth portion 211 is used to mesh with the first connecting tooth portion 21, and the second transmission tooth portion 212 is used to mesh with the first driving tooth portion 111. Between these two groups of teeth for meshing, at least one group is intermittently meshed, so that the driving gear 100 and the door body 20 are intermittently transmitted and connected.

[0067] In one embodiment, if Figure 10 As shown, the outer diameter of the transmission tooth portion 210 for meshing with the driving gear 100 is smaller than the outer diameter of the transmission tooth portion 210 for meshing with the first connecting tooth portion 21. That is, the outer diameter of the second transmission tooth portion 212 is smaller than the outer diameter of the first transmission tooth portion 211, so that the transmission ratio between the driving gear 100 and the first connecting tooth portion 21 can be amplified by the transmission tooth portion 210, and the movement amplitude requirement of the door body 20 opening and closing can be met. Furthermore, the axial distribution direction of the first transmission tooth portion 211 and the second transmission tooth portion 212 is in the same direction as the axial distribution direction of the first driving tooth portion 111 and the second driving tooth portion 112, and the first transmission tooth portion 211 avoids the driving gear 100 in the axial direction, and the axial projections of the first transmission tooth portion 211 and the driving gear 100 have an overlapping area, which is conducive to the compact layout inside the incomplete gear mechanism, thereby reducing the installation space required for the incomplete gear mechanism.

[0068] In one embodiment, if Figures 3 to 8 and Figure 10 As shown, the transmission gear 200 is also provided with two second locking arc portions 220, and the two ends of the transmission tooth portion 210 are respectively connected to the two ends of the second locking arc portion 220, the driving gear 100 is correspondingly provided with a first locking arc portion 120, and the door body 20 is correspondingly provided with a third locking arc portion 22, and the two second locking arc portions 220 are respectively used to lock and cooperate with the first locking arc portion 120 and the third locking arc portion 22, so that the door body 20 and the driving gear 100 are locked.

[0069] For the convenience of the following description, the two second locking arcs 220 are respectively referred to as the third sub-locking arc 221 and the fourth sub-locking arc 222. The third sub-locking arc 221 is used to lock and match with the third locking arc 22, and the fourth sub-locking arc 222 is used to lock and match with the first sub-locking arc 121. The central axes of the two locking arcs that are locked and matched coincide or substantially coincide, so that when one of the locking arcs rotates, the other locking arc can be stably in the current position. It should be noted that the locking arc that needs to rotate should be set as a convex arc, and the other locking arc that matches it corresponds to a concave arc.

[0070] Specifically, both ends of the third sub-locking arc portion 221 are respectively connected to both ends of the first transmission tooth portion 211, and both ends of the fourth sub-locking arc portion 222 are respectively connected to both ends of the second transmission tooth portion 212. That is, the third sub-locking arc portion 221 and the first transmission tooth portion 211 are connected to form a complete circumference, and the fourth sub-locking arc portion 222 and the second transmission tooth portion 212 are connected to form a complete circumference. Thus, when the first transmission tooth portion 211 disengages from the first connecting tooth portion 21, the second transmission tooth portion 212 will also simultaneously disengage from the first driving tooth portion 111, and the third sub-locking arc portion 221 will immediately lock and cooperate with the third locking arc portion 22, and the fourth sub-locking arc portion 222 will also immediately lock and cooperate with the first sub-locking arc portion 121 until the driving gear 100 is driven to be re-driven and connected to the first connecting tooth portion 21. Thereby, the locking effect on the door body 20 can be ensured. When the driving gear 100 drives the air guiding member 30 to swing, the door body 20 can stably be in the position of opening the air outlet 11, and in the shutdown state, the door body 20 can stably cover the air outlet 11.

[0071] In one embodiment, as Figures 3 to 8 shown, the inner side wall of the door body 20 is convexly arc-shaped protruding outward, and the first connecting tooth portion 21 is provided on the inner side wall of the door body 20. That is, the first connecting tooth portion 21 has a structure similar to an internal gear ring. Thus, it is convenient for the corresponding structure of the incomplete gear mechanism to cooperate, and at the same time, the space inside the door body 20 can be utilized to facilitate the compact layout of the incomplete gear mechanism. Of course, in other embodiments, it may also be that the door body 20 is provided with a gear structure, and the first connecting tooth portion 21 is arranged on the outer periphery of the gear structure.

[0072] In one embodiment, as Figures 3 to 8 shown, the second connecting tooth portion 31 is used to mesh with the driving gear 100. The air guiding member 30 is further provided with a fourth locking arc portion 32. Both ends of the second connecting tooth portion 31 are respectively connected to both ends of the fourth locking arc portion 32. The driving gear 100 is correspondingly provided with a first locking arc portion 120. The fourth locking arc portion 32 is used to lock and cooperate with the first locking arc portion 120 to lock the air guiding member 30 and the driving gear 100. Specifically, the second connecting tooth portion 31 intermittently meshes with the second driving tooth portion 112, and the fourth locking arc portion 32 intermittently locks and cooperates with the second sub-locking arc portion 122. The meshing of the two tooth portions and the locking cooperation of the two locking arc portions are carried out alternately. Thus, when performing the door opening and closing operation, through the locking cooperation of the fourth locking arc portion 32 and the first sub-locking arc portion 121, the air guiding member 30 can be maintained in the initial state, and the second connecting tooth portion 31 can stably be in the preset position and wait for the next meshing of the second driving tooth portion 112.

[0073] Without loss of generality, as Figure 1 and Figure 2As shown, the air conditioner is configured with a door body 20. By sliding the door body 20 to one side, the air outlet 11 can be opened or closed. Of course, the door body 20 can also be configured as two.
