Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0029] This application provides an air guiding mechanism to solve the problem of limited air guiding angle. The following description will be provided in conjunction with the accompanying drawings.

[0030] In the embodiments of this application, such as Figure 1 and Figure 2 As shown, the air guiding mechanism includes:

[0031] The drive assembly includes a wheel 2 and a driver for driving the wheel 2 to rotate. The wheel 2 is provided with a groove 21, and multiple portions of the groove 21 are radially distanced from the axis of rotation of the wheel 2.

[0032] The air guide 1 is used to slide and connect to the housing 5 of the indoor unit of the air conditioner. The air guide 1 is provided with a slider 13 that is slidably connected to the slide groove 21.

[0033] There is an angle between the rotating shaft of the wheel 2 and the sliding direction of the air guide 1, and the wheel 2 rotates to change the position of the slider 13 in the groove 21.

[0034] It should be noted that the air guide 1 refers to a structure that guides airflow. "Multiple portions on the slide 21" refers to different locations within the slide 21. It is conceivable that at least part of the slide 21 does not extend circumferentially along the axis of rotation of the wheel 2. "An angle exists between the axis of rotation of the wheel 2 and the sliding direction of the air guide 1" means that the angle between the axis of rotation of the wheel 2 and the sliding direction of the air guide 1 is not equal to 0° and not equal to 180°. For example, the axis of rotation of the wheel 2 can be perpendicular to the sliding direction of the air guide 1.

[0035] It is understandable that, since at least part of the extension direction of the groove 21 on the wheel 2 is not along the circumferential direction of the wheel 2's axis of rotation, when the wheel 2 rotates, the slider 13 slides relative to the extension direction of the groove 21. The slider 13 will gradually slide to a position with a different radial distance from the wheel 2's axis of rotation. During the above sliding process, the air guide 1 moves with the slider 13, thereby sliding relative to the wheel 2, realizing that the position of the air guide 1 relative to the air conditioner indoor unit casing 5 is adjustable, and increasing the air guide angle of the air guide mechanism.

[0036] It should be noted that the slider 13 does not slide actively within the groove 21. Instead, the position of the slider 13 within the groove 21 is changed by the rotation of the wheel 2 and the sliding characteristics of the air guide 1.

[0037] For example, the sliding direction of the air guide 1 can be vertical, and the aforementioned air guide mechanism can be applied to a floor-standing air conditioner indoor unit. Since the air guide 1 is slidably connected to the housing 5 of the air conditioner indoor unit, the side wall of the slide groove 21 facing away from the ground provides upward support for the slider 13 and the air guide 1. The sliding direction of the air guide 1 can also be vertical, so that the sliding connection between the air guide 1 and the housing 5 of the air conditioner indoor unit can provide upward support for the air guide 1, which is more conducive to the wheel 2 driving the air guide 1 to slide. Accordingly, the aforementioned air guide mechanism can be applied to a wall-mounted air conditioner indoor unit.

[0038] The driver is fixedly connected to the housing 5. The driver can be a motor or other common rotating structure.

[0039] In some embodiments, such as Figure 2 and Figure 3 As shown, the chute 21 includes a plurality of arc-shaped groove segments 211 connected in sequence. The plurality of arc-shaped groove segments 211 are arranged around the rotating shaft of the wheel 2, and at least two of the plurality of arc-shaped groove segments 211 have different radial distances from the rotating shaft of the wheel 2.

[0040] It should be noted that in this embodiment, multiple arc-shaped groove segments 211 correspond to multiple parts of the slide groove 21. Multiple arc-shaped groove segments 211 means that multiple parts of the slide groove 21 extend along an arc. The arc center of the arc extension direction of some arc-shaped groove segments 211 is located on the rotating shaft of the wheel 2, while the arc center of the arc extension direction of some arc-shaped groove segments 211 is not located on the rotating shaft of the wheel 2. Furthermore, some arc-shaped groove segments 211 are located on the side of some arc-shaped groove segments 211 that is far away from the rotating shaft of the wheel 2, forming a layered surround in the radial outward direction of the wheel 2.

[0041] Understandably, when slider 13 moves relative to the rotating shaft of the wheel 2 within the arc-shaped groove 211, the positions of slider 13 and air guide 1 relative to the rotating shaft of the wheel 2 remain fixed, and similarly, their positions relative to the housing 5 also remain fixed. However, when slider 13 moves relative to the rotating shaft of the wheel 2 within the arc-shaped groove 211 whose center is not located on the rotating shaft of the wheel 2, slider 13 and air guide 1 move radially along the rotating shaft of the wheel 2, changing their positions relative to the housing 5. Since there are multiple arc-shaped grooves 211 with different radial distances from the rotating shaft of the wheel 2, when slider 13 moves between these multiple arc-shaped grooves 211, air guide 1 slides, thus changing its position relative to the housing 5.

[0042] In some embodiments, such as Figure 3 As shown, the extension directions of the multiple arc-shaped groove segments 211 form a spiral shape.

[0043] It should be noted that "the extension direction of multiple arc-shaped groove segments 211 forms a spiral" means that the path left by the slider 13 as it passes through multiple arc-shaped groove segments 211 in sequence is the trajectory of a moving point that rotates around the axis of the wheel 2 and gradually moves away from it, similar to an Archimedean spiral or a planar spiral.

[0044] It is understandable that by sliding within the aforementioned arc-shaped groove 211, the air guide 1 can reciprocate about the radial direction of the wheel 2 axis, increasing the range of movement of the air guide 1 relative to the housing 5 and further expanding the air guiding range.

[0045] In some embodiments, such as Figure 2 and Figure 3 As shown, the slide 21 also includes a reversing groove 212, which connects two radially adjacent arc-shaped groove segments 211 of the wheel 2 to guide the slider 13 into another arc-shaped groove segment 211.

[0046] It should be noted that, since the groove 21, which is approximately an Archimedean spiral or a planar spiral, can only enable the slider 13 to move in one direction and the movement distance is limited; while the reversing groove 212 can guide the slider 13 to the arc-shaped groove 211 near the rotating shaft of the wheel 2, ensuring that the slider 13 can continuously move within the groove 21.

[0047] It is understood that by designing the extension direction of the arc-shaped groove segment 211 and the reversing groove 212, the slider 13 can be guided into another arc-shaped groove segment 211. For example, the end of an arc-shaped groove segment 211 is selected and extended inward along the direction close to the axis of rotation of the wheel 2 until it connects with another arc-shaped groove segment 211.

[0048] In some embodiments, such as Figure 3 As shown, the reversing groove 212 penetrates the groove wall of multiple arc-shaped groove segments 211 to connect the innermost arc-shaped groove segment 211 with the outermost arc-shaped groove segment 211. The reversing groove 212 is used to switch the slider 13 between the outermost arc-shaped groove segment 211 and the innermost arc-shaped groove segment 211.

[0049] It should be noted that the commutation groove 212 forms a closed loop with the original Archimedes spiral or planar spiral groove 21.

[0050] Understandably, after completing one movement cycle, slider 13 re-enters the next movement cycle using reversing groove 212. Specifically, this can be achieved by connecting the beginning and end of the original groove 21, which is approximately an Archimedean spiral or a planar spiral, using reversing groove 212.

[0051] In some embodiments, such as Figure 2As shown, the slider 13 is rotatably connected to the air guide 1. The slider 13 has two guide surfaces 131 arranged opposite to each other. The two guide surfaces 131 are respectively arranged towards the groove wall of the slide 21. The distance between the two guide surfaces 131 gradually decreases along the direction away from the axis of rotation of the slider 13.

[0052] It should be noted that the guide surface 131 gives the slider 13 a spindle-shaped structure that is small at both ends and large in the middle. It can be understood that by rotatably connecting the slider 13 to the air guide 1, the two guide surfaces 131 adapt to the extension direction of the arc-shaped groove segment 211. When the slider 13 moves to the junction of the arc-shaped groove segment 211 and the reversing groove 212, it prevents the slider 13 from entering the non-target arc-shaped groove segment 211, thus smoothly guiding the slider 13 into the target arc-shaped groove segment 211 to begin the next movement cycle.

[0053] For example, the length between the two ends of the slider 13 is preferably greater than the width of the arc-shaped groove segment 211, so that when the slider 13 moves to the junction of the arc-shaped groove segment 211 and the reversing groove 212, the two ends of the slider 13 can abut against the groove wall of the reversing groove 212 near the arc-shaped groove segment 211, preventing the slider 13 from entering the non-target arc-shaped groove segment 211.

[0054] In some embodiments, such as Figure 2 and Figure 4 As shown, the air guide 1 includes a connecting seat 11 and multiple air guide plates 12, which are spaced apart on the connecting seat 11.

[0055] It is understood that the connecting seat 11 enables the synchronous movement of multiple air guide plates 12. The multiple air guide plates 12 can be identical or different, and can present different angles relative to the connecting seat 11 to expand the air guiding range. The multiple air guide plates 12 can be arranged side-by-side at intervals along the sliding direction of the air guide 1, or they can be arranged in multiple rows along a direction perpendicular to the sliding direction of the air guide 1.

[0056] Specifically, the connecting seat 11 is slidably connected to the housing 5, and the sliding direction of the connecting seat 11 is perpendicular to the rotation axis of the wheel 2; the slider 13 is rotatably connected to the connecting seat 11, and the rotation axis of the slider 13 is parallel to the rotation axis of the wheel 2. In addition, multiple air guide plates 12 are rotatably connected to the connecting seat 11, and their air guiding direction can be adjusted by manually driving the air guide plates 12 to rotate.

[0057] In some embodiments, such as Figure 2 and Figure 4 As shown, the air guiding mechanism also includes a rack 3 that meshes with each other and multiple gears 4. The rack 3 is used to be mounted on the housing 5. The extending direction of the rack 3 is the same as the sliding direction of the air guiding component 1. The multiple gears 4 are connected to multiple air guiding plates 12 one by one. The multiple air guiding plates 12 are rotatably connected to the connecting seat 11.

[0058] Understandably, when the wheel 2 drives the slider 13 and the connecting seat 11 to move relative to each other, the gear 4 moves with the connecting seat 11 and rotates simultaneously with the rack 3 to drive the air guide plate 12 to rotate. Therefore, when the wheel 2 drives the air guide component 1 to move, the relative movement between the rack 3 and the gear 4 will drive the air guide plate 12 to rotate, which not only adjusts the overall position of the air guide component 1, but also adjusts the air guiding angle of the air guide plate 12, greatly increasing the air guiding range.

[0059] In some embodiments, such as Figure 4 As shown, the connector 11 is provided with multiple slots 111, and multiple air guide plates 12 are engaged with the multiple slots 111 in a one-to-one correspondence.

[0060] It should be noted that the rotating part of the air guide plate 12 is engaged in the slot 111, which allows the air guide plate 12 to rotate on the connecting seat 11. It can be understood that the engagement between the air guide plate 12 and the slot 111 allows for the maintenance and replacement of a single air guide plate 12.

[0061] For example, the slot 111 extends through one side of the connecting seat 11 in a direction perpendicular to the sliding direction of the air guide 1, and the width of the slot 111 gradually increases along the through direction of the slot 111. In this way, when the air guide plate 12 is inserted into the slot 111, the groove wall of the slot 111 can gradually press against the air guide plate 12.

[0062] This application also provides an air conditioner indoor unit, which includes a housing 5 and an air guide mechanism as described above. The specific structure of the air guide mechanism is as described in the above embodiments. Since this air conditioner indoor unit adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. Among them, the air guide 1 is slidably connected to the housing 5.

[0063] In some embodiments, such as Figure 1 As shown, multiple support seats 51 are spaced apart on the housing 5, and the support seats 51 are sleeved on the connecting seat 11. This ensures that multiple gears 4 can mesh tightly with the rack 3.

[0064] In the above embodiments, the descriptions of each embodiment have different focuses. Parts not described in detail in a particular embodiment can be referred to in the relevant descriptions of other embodiments. In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features.
