[0043] The utility model provides an air conditioner.

[0044] See also Figures 1 to 11 In one embodiment of the utility model, the air conditioner comprises:

[0045] The housing 10 is provided with an air outlet 11;

[0046] Two door bodies 20 distributed along the width direction of the air outlet 11, and arranged at the air outlet 11 in an openable and closable manner;

[0047] 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

[0048] A driving member (not shown) is connected to the door body 20 and the air guide member 30 through an incomplete gear mechanism;

[0049] From the initial state of the air conditioner, the driving member can alternately drive the two door bodies 20 to open the air outlet 11 and drive the air guide member 30 to swing.

[0050] 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 the incomplete gear mechanism, so that the same driving member can drive the two door bodies 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 two door bodies 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. Without loss of generality, the air conditioner is also provided with a gear box 40, and the incomplete gear mechanism is accommodated and installed in the gear box 40.

[0051] When the air conditioner is in standby mode, the two doors 20 cover the air outlet 11, and the air guide 30 is accommodated inside the two doors 20. At this time, the matching state of the incomplete gear mechanism is as follows: Figure 6 and Figure 7 shown.

[0052] When the air conditioner is turned on, the driving member starts, which enables the incomplete gear mechanism to be connected to the two door bodies 20 and disconnect the transmission connection with the air guide member 30. Therefore, the driving member will only drive the two door bodies 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 two door bodies 20. At this time, the cooperation state of the incomplete gear mechanism is as follows: Figure 8 and Figure 9 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.

[0053] 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 two door bodies 20 can also maintain the position of opening the air outlet 11. Figure 10 and Figure 11 , the air guide member 30 also reaches the limit position on the other side.

[0054] 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.

[0055] 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 two door bodies 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 two door bodies 20 are 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 two door bodies 20 to cover the air outlet 11. In particular, the air guide member 30 is tilted 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.

[0056] 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.

[0057] In one embodiment, the air conditioner is configured as a cabinet unit.

[0058] 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.

[0059] 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 11, 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.

[0060] In one embodiment, the driving member drives the two door bodies 20 to rotate in opposite directions to open or close the air outlet 11, and the rotation axis of the door body 20 is located on the door body 20 or outside the door body 20. When the rotation axis of the door body 20 is located on the door body 20, the air outlet 11 can be opened by turning the two door bodies 20 outward in opposite directions, and the air outlet 11 can be covered by buckling the two door bodies 20 relative to each other; when the rotation axis of the door body 20 is located outside the door body 20, the two door bodies 20 can be regarded as sliding relative to the housing 10 along an arc trajectory, and the air outlet 11 can be closed by sliding the two door bodies 20 toward each other, and the air outlet 11 can be opened by sliding the two door bodies 20 away from each other.

[0061] In one embodiment, if Figure 3 and Figure 4As shown in the figure, the incomplete gear mechanism includes a driving gear 100, a first transmission gear 200, and a second transmission gear 300. The driving member is drivingly connected to the driving gear 100. The driving gear 100 is alternately drivingly connected to the first transmission gear 200 and the second transmission gear 300. The first transmission gear 200 is used to drive the two door bodies 20 to open and close, and the second transmission gear 300 is used to drive the air guiding member 30 to swing. That is to say, the driving gear 100 can be indirectly drivingly connected to the two door bodies 20 through the first transmission gear 200, and can be indirectly drivingly connected to the air guiding member 30 through the second transmission gear 300, reducing the difficulty of the structural design and the spatial layout of the driving gear 100. Of course, in other embodiments, it may also be that at least one of the door body 20 and the air guiding member 30 is provided with a rack structure, and the driving gear 100 is drivingly connected to the corresponding door body 20 or the air guiding member 30 by directly meshing with the rack structure.

[0062] In one embodiment, as Figures 3 to 5 shown, there are two driving gears 100 and two first transmission gears 200. The two driving gears 100 are meshed with each other. The driving member is drivingly connected to one of the driving gears 100. The two first transmission gears 200 are intermittently meshed with the two driving gears 100 respectively, and are drivingly connected to the two door bodies 20 one by one. In this way, the driving member can drive the two first transmission gears 200 to rotate in opposite directions, facilitating the two first transmission gears 200 to drive the two door bodies 20 to rotate in opposite directions, thereby driving the opening and closing of the two door bodies 20. Of course, in other embodiments, it may also be that a linkage structure, such as a link mechanism, is provided between the two door bodies 20. The driving gear 100 drives one of the door bodies 20 to move through a transmission gear, and the other door body 20 can be driven to move accordingly.

[0063] In one embodiment, as Figure 4 and Figure 5 shown, at least one driving gear 100 is provided with a first driving tooth portion 111 and a second driving tooth portion 121 distributed along the axial direction. The first transmission gear 200 and the second transmission gear 300 are intermittently meshed with the first driving tooth portion 111 and the second driving tooth portion 121 respectively. In this way, differential design can be carried out for the first driving tooth portion 111 and the second driving tooth portion 121 respectively, so that the transmission ratio between the first driving tooth portion 111 and the first transmission gear 200 is different from the transmission ratio between the second driving tooth portion 121 and the second transmission gear 300. When the driving member rotates at the same speed, the two door bodies 20 can open at an appropriate speed, and the air guiding member 30 can also swing at an appropriate speed. Of course, in other embodiments, it may also be that the driving gear 100 is alternately meshed with the first driving tooth portion 111 and the second driving tooth portion 121 through the same tooth portion.

[0064] In one embodiment, as Figures 4 to 11 shown, both of the driving gears 100 are provided with the first driving tooth portion 111 and the second driving tooth portion 121. Two corresponding second transmission gears 300 are provided. The two second transmission gears 300 are respectively intermittently engaged with the two second driving tooth portions 121 for drivingly connecting to different air guiding members 30. That is to say, more than two air guiding members 30 are provided at the air outlet 11 to improve the air guiding effect. In this embodiment, the rotation directions of the two second transmission gears 300 are opposite. If both transmission gears are directly connected to the corresponding air guiding members 30, different air guiding members 30 can be driven to swing in opposite directions, which is beneficial to dispersing the air and reducing the direct blowing feeling of the air, thereby improving the comfort of the user. If one of the second transmission gears 300 is also engaged with a transmission gear on the opposite side of the driving gear 100 and finally drives the air guiding member 30 through this transmission gear, the two air guiding members 30 driven by the two second transmission gears 300 can rotate in the same direction. The multiple air guiding members 30 provided at the air outlet 11 can be linked by a connecting rod to form an air guiding assembly that swings synchronously. In this embodiment, driving the air guiding assembly by the two second transmission gears 300 can more reliably drive the air guiding assembly to swing. Of course, in other embodiments, it may also be that only one second transmission gear 300 is provided to drive the aforementioned air guiding assembly.

[0065] In one embodiment, as Figure 5 shown, both the first driving tooth portion 111 and the second driving tooth portion 121 are incomplete tooth portions. The two driving gears 100 can be engaged through at least one of a pair of the first driving tooth portions 111 and a pair of the second driving tooth portions 121. That is to say, among the two driving gears 100, if the two first driving tooth portions 111 are disengaged, the two second driving tooth portions 121 will remain in the engaged state. If the two second driving tooth portions 121 are disengaged, the two first driving tooth portions 111 will remain in the engaged state. Of course, the two first driving tooth portions 111 and the two second driving tooth portions 121 can also be in the engaged state at the same time. In this way, it can be ensured that the two driving gears 100 are stably in the engaged and mating state, and the driving member can stably drive the transmission gears on both sides.

[0066] It should be noted that the above-mentioned meshing and mating relationship is only reflected in the rotation process of the driving gear 100. It can be understood that the driving gear 100 rotates reciprocally within a range, and this range can be an angle less than 360 degrees. That is to say, there can be an overlapping part between the notches of the first driving tooth portion 111 and the second driving tooth portion 121, as long as the driving gear 100 does not rotate into the overlapping range of the notches.

[0067] In other embodiments, it is also possible that the first transmission gear 200 or the second transmission gear 300 is configured as an incomplete gear. When one of the two gears is configured as an incomplete gear, intermittent meshing can be achieved.

[0068] In one embodiment, as Figure 5 shown, the central angle of the first driving tooth portion 111 is greater than the central angle of the second driving tooth portion 121. In this way, the driving gear 100 can drive the first transmission gear 200 to rotate by a larger amplitude through the first driving tooth portion 111, which is beneficial to meeting the movement range required for the opening and closing of the door body 20. The rotation amplitude of the driving gear 100 driving the second transmission gear 300 through the second gear is relatively smaller, which is beneficial to meeting the requirements of the air deflector 30 for the sweeping angle.

[0069] In one embodiment, as Figure 5 shown, the outer diameter of the first driving tooth portion 111 is greater than the outer diameter of the second driving tooth portion 121. It can be understood that when the outer diameters of the first transmission gear 200 and the second transmission gear 300 are the same, the outer diameter of the first driving tooth portion 111 being greater than the outer diameter of the second driving tooth portion 121 can make the transmission ratio between the first driving tooth portion 111 and the first transmission tooth portion greater than the transmission ratio between the second driving tooth portion 121 and the second transmission gear 300. When the rotational speed of the driving member remains the same, the rotational speed of the door body 20 will be greater than the rotational speed of the air deflector 30, which can meet the different requirements of the door body 20 and the air deflector 30 for the rotational speed. Therefore, the outer diameter of the first driving tooth portion 111 being greater than the outer diameter of the second driving tooth portion 121 can help the door body 20 to open and close at a faster speed, and enable the air deflector 30 to sweep the air at a relatively gentle speed. Of course, in other embodiments, it is also possible to change the size relationship between the outer diameters of the first transmission gear 200 and the second transmission gear 300 to make the transmission ratio between the first driving tooth portion 111 and the first transmission tooth portion greater than the transmission ratio between the second driving tooth portion 121 and the second transmission gear 300.

[0070] In one embodiment, as Figures 6 to 11As shown, the drive gear 100 is further provided with a first locking arc portion 112. Two ends of the first locking arc portion 112 are respectively connected to two ends of the first driving tooth portion 111. The first transmission gear 200 is correspondingly provided with a third locking arc portion 210. The first locking arc portion 112 and the third locking arc portion 210 are intermittently locked and engaged. That is to say, the first locking arc portion 112 and the first driving tooth portion 111 are connected to form a complete circumference, and the third locking arc portion 210 and the tooth portion of the first transmission gear 200 are connected to form a complete circumference. In this way, after the first drive gear 100 disengages from the tooth portion of the first transmission gear 200, the first locking arc portion 112 will immediately be locked and engaged with the third locking arc portion 210, and the first transmission gear 200 can stably stay in the current position, waiting for the first driving tooth portion 111 of the drive gear 100 to mesh again. Thereby, the locking effect on the door body 20 can be ensured. When the drive gear 100 drives the air guiding member 30 to swing, the door body 20 can stably stay in the position of opening the air outlet 11. In the shutdown state, the door body 20 can stably cover the air outlet 11.

[0071] In an embodiment, as Figures 6 to 11 shown, the drive gear 100 is further provided with a second locking arc portion 122. Two ends of the second locking arc portion 122 are respectively connected to two ends of the second driving tooth portion 121. The second transmission gear 300 is correspondingly provided with a fourth locking arc portion 310. The second locking arc portion 122 and the fourth locking arc portion 310 are intermittently locked and engaged. That is to say, the second locking arc portion 122 and the second driving tooth portion 121 are connected to form a complete circumference, and the fourth locking arc portion 310 and the tooth portion of the second transmission gear 300 are connected to form a complete circumference. In this way, after the second drive gear 100 disengages from the tooth portion of the second transmission gear 300, the second locking arc portion 122 will immediately be locked and engaged with the fourth locking arc portion 310, and the second transmission gear 300 can stably stay in the current position, waiting for the second driving tooth portion 121 of the drive gear 100 to mesh again. Thereby, during the operation of opening and closing the door, the air guiding member 30 can be maintained in the initial state through the locking and engagement between the fourth locking arc portion 310 and the second locking arc portion 122.

[0072] It can be understood that the central axes of the two locking arc portions that are locked and engaged with each other coincide or are substantially coincident, so that when one of the locking arc portions rotates, the other locking arc portion can stably stay in the current position. It should be noted that the locking arc portion that needs to rotate should be set as a convex arc portion, and the other locking arc portion that cooperates with it is correspondingly a concave arc portion.

[0073] In an embodiment, as Figure 4As shown, the first transmission gear 200 and the second transmission gear 300 are axially distributed. That is, the first transmission gear 200 and the second transmission gear 300 are arranged in a relative position similar to being stacked. In this way, the structure of the incomplete gear mechanism can be made more compact, and the installation space required for the incomplete gear mechanism can be reduced. It can be understood that the first transmission gear 200 and the second transmission gear 300 should be cooperated without power, and they can be arranged at intervals or in contact cooperation without friction.

[0074] Based on the distribution mode of the first transmission gear 200 and the second transmission gear 300, the air guide member 30 and the door body 20 can be cooperated with the corresponding transmission gears in the following several ways, but are not limited to the following several ways.

[0075] First, the first transmission gear 200 and the second transmission gear 300 can be cooperated with the air guide member 30 or the door body 20 through the outer peripheral side. Specifically, a connecting gear is arranged at the end of the air guide member 30, and a connecting gear is correspondingly arranged at the end of the door body 20 corresponding to the rotation axis of the door body 20. When the rotation axis of the door body 20 is located outside the door body 20, an end plate is arranged on the inner side of the end of the door body 20, and the connecting gear is arranged on the end plate. Both the air guide member 30 and the door body 20 are meshed and cooperated with the corresponding transmission gears through the connecting gears. Or, an arc-shaped connecting rack structure is distributed along the width direction on the inner side wall of the door body 20, and is meshed with the first transmission gear 200 through the connecting rack structure.

[0076] Second, the air guide member 30 and the door body 20 are fixedly connected to the rotation centers of the corresponding transmission gears on the same side in the axial direction of the two transmission gears.
