Detailed Description

An embodiment of the present invention provides a wall-mounted air conditioner indoor unit, which may include a casing 10. The front side surface of the housing 10 is provided with at least one circular air outlet 11. For example, the circular outlets 11 may be provided in plural, preferably two, and arranged in line in the longitudinal direction of the indoor unit. The wall-mounted air conditioning indoor unit further includes an opening and closing structure 20 for the circular outlet 11. As shown in fig. 1-4, each opening and closing structure 20 may include a central baffle 21 and a plurality of curved blades 22.

The central baffle 21 is fixedly disposed at the center of the circular outlet 11, and an air outlet area is formed between the outer periphery of the central baffle and the inner periphery of the circular outlet 11. For example, the central baffle 21 may be circular, and the corresponding outlet area is annular. In alternative embodiments of the present invention, the central baffle 21 may have other shapes such as a square shape, an oval shape, and the like.

The plurality of curved blades 22 are arranged in series in the circumferential direction of the central baffle 21, and for example, the number of the curved blades 22 may be 6 and may be arranged uniformly along the circumference of the central baffle 21. In other embodiments, the number of the blades may also be less than 6 or more than 6, and may be specifically set according to the size of the blades, the size of the central baffle 21, and the size of the circular air outlet 11. The plurality of curved blades 22 may converge toward the center of the central baffle 21 to at least partially open the wind outlet region, and may converge completely to the front or rear side of the central baffle 21. Preferably, the air outlet can be completely gathered and contracted to the rear side of the central baffle 21, that is, when the plurality of curved blades 22 are in the completely gathered state, the central baffle 21 can shield the plurality of curved blades 22, and the user cannot observe the curved blades 22 from the outside of the air outlet, as shown in fig. 2. The plurality of curved blades 22 may also be flared away from the center of the central baffle 21 to at least partially enclose the wind exit region. As shown in fig. 1, the plurality of curved blades 22 can be unfolded to completely cover the annular air outlet region, so as to achieve the overall sealing of the air outlet.

Fig. 5, 6 and 7 are schematic front, top and bottom views, respectively, of the curved blades 22 of the opening and closing structure 20 according to another embodiment of the present invention. As shown in fig. 5 to 7, the curved blade 22 is approximately crescent shaped having an outer profile edge portion which is convex and an inner profile edge portion which is concave. The inner contour edge portion is disposed toward the center of the central baffle when the plurality of curved blades are gathered, and accordingly, the outer contour edge portion may face the inner periphery of the circular outlet when the plurality of curved blades are gathered, as shown in fig. 9. The outer and inner contoured edge portions together define the root and tip ends of the curved blade 22.

As shown in fig. 5-7, in some embodiments of the invention, the outer contoured edge portion of the curved blade 22 includes a first circular arc-shaped section 221 and a second circular arc-shaped section 222. The inner contour edge portion comprises a third circular arc shaped section 223 and a fourth circular arc shaped section 224. The first and fourth circular arc-shaped sections 221, 224 are progressively closer towards the root end of the curved blade 22, such that the root end of the curved blade 22 forms a tapered curved region. The second and third circular arc-shaped

sections

222, 223 are progressively closer towards the tip of the curved blade 22 so that the tip of the curved blade 22 also forms a tapered curved region. That is, the first and fourth circular arc-shaped sections gradually approach in a direction towards the root end of the curved blade such that the root end of the curved blade forms a tapered curved region. The second and third circular arc shaped sections are gradually closer together in a direction towards the tip of the curved blade so that the tip of the curved blade forms a tapered curved region.

In some preferred embodiments of the present invention, the curvature of the first circular arc-shaped section 221 is equal to the curvature of the outer periphery of the central baffle 21, so that when the plurality of curved blades 22 are completely gathered to the rear side of the central baffle 21, the first circular arc-shaped section 221 of the plurality of curved blades 22 coincides with the outer periphery of the central baffle 21, as shown in fig. 9. And a partial region of each of the curved blades 22 is located between two adjacent ones of the curved blades 22 after the plurality of curved blades 22 are gathered. The curvature of the second arc-shaped section 222 is equal to the curvature of the inner periphery of the air outlet, so that when the plurality of curved blades 22 are fully unfolded to cover the air outlet region, the second arc-shaped section 222 of the plurality of curved blades 22 is overlapped with the inner periphery of the air outlet, as shown in fig. 8. By such design, the plurality of curved blades 22 can be completely folded to the rear side of the central baffle 21 or completely unfolded to shield the air outlet area, so that the appearance of the air outlet is more complete and beautiful.

In addition, the curvature and length of the third circular arc shaped section 223 are both equal to the curvature and length of the first circular arc shaped section 221. In this embodiment, when the plurality of curved blades 22 are completely unfolded to cover the air outlet region, as shown in fig. 8, the first arc-shaped section 221 and the third arc-shaped section of two adjacent curved blades 22 are just spliced together, so that the plurality of curved blades 22 can completely cover the air outlet region, and meanwhile, the adjacent curved blades 22 are not overlapped as much as possible, so that the size of the curved blades is fully utilized, and the appearance of the air outlet is more complete and beautiful.

In some embodiments of the invention, to facilitate the gathering and unfolding of the plurality of curved blades, each curved blade is preferably rotatably disposed about its root end on either the front or rear side of the central barrier. For example, as shown in fig. 8 and 9, each curved blade is rotatable about its root end to the rear side of the central barrier, with a plurality of curved blades arranged in a stack one above the other.

Further, the first arc-shaped section 221 further has a guiding flange 225 that is gradually higher from the root end adjacent to the curved blade 22 to the direction away from the root end, so as to guide the curved blades 22 in the front-rear direction of the indoor unit when the curved blades 22 are contracted or expanded, so that the curved blades 22 can be at least partially overlapped. Specifically, after the plurality of curved blades are gathered, a partial region of the tip of one curved blade 22 is located on the rear side of a partial region of the root end of the other curved blade 22 in each adjacent two curved blades 22, and the first arc-shaped section of each curved blade has a guide flange protruding toward the rear side of the curved blade and gradually rising from the root end adjacent to the curved blade toward the direction away from the root end. Or, after the plurality of curved blades are gathered, in every two adjacent curved blades 22, a partial region of the tip of one curved blade 22 is located at the front side of a partial region of the root end of the other curved blade 22, and the first arc-shaped section of each curved blade has a guide flange which protrudes to the front side of the curved blade and is gradually higher from the root end adjacent to the curved blade to the direction far away from the root end.

This is so because during the collapsing of the plurality of curved blades 22, there may be mechanical interference between adjacent curved blades 22. The guide flange 225 is located at a lower position near the root end and a higher position away from the root end, and when the adjacent curved blades 22 are folded to overlap each other, the guide flange 225 can guide the adjacent blades to slightly move toward the rear side so that the adjacent curved blades 22 are staggered in the front-rear direction of the opening and closing structure 20 to prevent mechanical interference.

In some embodiments of the invention, the root end of the curved blade 22 is provided with a blade pivot 26, and the curved blade 22 is pivotally connected to the rear side of the central barrier 21 adjacent the edge by the blade pivot 26, such that the curved blade 22 can rotate bi-directionally about the blade pivot 26. The plurality of curved blades 22 are spread or gathered by rotation about the blade pivot axis 26. As shown in fig. 8 and 9, when the plurality of curved blades 22 are rotated clockwise (as viewed from the direction in which the viewer points from the rear side to the front side of the wall-mounted air conditioning indoor unit) about the blade rotation shaft 26 from the state of fig. 8, they are folded toward the center barrier 21 to the position of fig. 9. When the plurality of curved blades 22 are rotated counterclockwise around the blade rotation axis 26 from the state of fig. 9, they are rotated and spread toward the outlet edge, and the position state of fig. 8 can be restored.

In some embodiments of the present invention, the opening and closing structure 20 further comprises a curved blade drive mechanism. The curved blade driving mechanism is used for driving each curved blade 22 to rotate along the blade rotating shaft 26 thereof so as to open or close the wind outlet area. For example, in some alternative embodiments, the curved blade drive mechanism may be a plurality of linkages, each linkage associated with a corresponding curved blade 22, and a stepper motor coupled to the plurality of linkages. The stepper motor rotates the curved blade 22 through a linkage mechanism.

As shown in fig. 10 and 11 (and to illustrate more clearly the principle of operation of the curved blade 22 drive mechanism, only a single curved blade 22 is shown in fig. 10 and 11), in some preferred embodiments of the invention the curved blade drive mechanism may include a steering wheel 23. The guide plate 23 is circular, is disposed behind the center fence 21, has a center coinciding with the center of the center fence 21, and is rotatable in both directions about a straight line passing through the center of the guide plate and perpendicular to the plane in which the guide plate is disposed, i.e., rotatable about its central axis in a first direction or rotatable about its central axis in a second direction opposite to the first direction.

Further, the rear side surface of the guide tray 23 is provided with a plurality of curved guide grooves 231 extending from the middle portion (may also be referred to as a middle region, a central region) to the edge of the guide tray 23. The number of curved guide slots 231 is the same as the number of curved blades 22, each curved guide slot 231 cooperating with a corresponding curved blade 22. For example, each curved blade further comprises a guiding stud 27, one end of the guiding stud 27 being fixable to the rear side of the curved blade 22 and the other end being snapped into the corresponding curved guiding slot 231. That is, each curved guide slot is adapted to receive a guide post to force the guide post along the curved guide slot to rotate the corresponding curved blade as the guide post is rotated in both directions about its central axis.

In some preferred embodiments of the invention, the guiding studs 27 may be arranged at the edge of the inner profile of the curved blade 22, and the guiding studs 27 are perpendicular to the plane of the guiding plate 23. Preferably, the guide post 27 may be located on the guide post fixing section between the third circular arc section 223 and the fourth circular arc section 224, and the guide post 27 and the blade rotation shaft 26 protrude toward the same direction. Further, the distance from the point on the guide groove 231 to the blade rotation axis 26 of the corresponding curved blade 22 gradually increases in the radial direction of the guide disk 23. That is, the distance from the point of the guide groove 231 near the edge of the guide disk 23 to the vane rotary shaft 26 is greater than the distance from the point near the center of the guide disk 23 to the vane rotary shaft 26.

In actual use, as shown in fig. 10, when the curved blades 22 are in the fully extended state, the guide posts 27 are located in the guide slots 231 near the edges of the guide discs 23. When the curved blades 22 need to be furled, the guiding disc 23 is driven to rotate clockwise, the distance from the curved guiding slot 231 to the blade rotating shaft 26 corresponding to the curved blade 22 increases, the guiding post 27 is forced to slide along the curved guiding slot 231 toward the center position of the guiding disc 23, and the curved blades 22 are driven to rotate and furl toward the center direction of the central baffle 21, as shown in fig. 11. When the guide posts 27 move to the end of the curved guide slots 231 near the center of the guide plate 23, the curved blades 22 are fully retracted to the rear side of the central baffle 21. When the curved blades 22 need to be unfolded, the guiding disc 23 is driven to rotate counterclockwise, the distance from the curved guiding slot 231 to the blade rotating shaft 26 corresponding to the curved blades 22 is reduced, the guiding column 27 is forced to slide along the curved guiding slot 231 towards the edge position of the guiding disc 23, and the curved blades 22 are driven to rotate and unfold towards the edge direction of the circular air outlet 11. When the guide posts 27 move to the end of the curved guide slots 231 near the edge of the guide disk 23, the curved blades 22 are fully deployed to close the wind outlet region.

In some embodiments of the present invention, in order to facilitate the rotation of the guiding disc 23, the middle portion of the guiding disc 23 further has a circular opening 233, and a ring gear is disposed around the inner side of the circular opening 233. The curved blade drive mechanism may also include a steering wheel gear and steering wheel motor 25. The guide disc gear is arranged in the circular opening 233 of the guide disc 23 and is meshed with the gear ring on the inner side of the circular opening 233, and the guide disc motor 25 is used for driving the guide disc gear to rotate so as to drive the guide disc 23 to rotate. The steering wheel motor 25 may be a rotary motor.

In some embodiments of the invention, further, in order that the guide disc 23 does not deviate from the track during rotation, the edge of the central baffle 21 may be provided with a flange projecting rearwards, in the area of which the guide disc 23 rotates. Preferably, the periphery of the flange may further be provided with a plurality of shaft fixing pieces 211 protruding toward the center of the guide plate 23. The pivot fixing pieces 211 can be used to set the blade pivot 26 of the curved blade 22, on the one hand, and to define the movement path of the guide disk 23 in the front-rear direction, on the other hand.

In some embodiments of the present invention, the guiding plate 23 is further provided with a plurality of limiting grooves 232, which are arranged at intervals along a concentric circle on the guiding plate 23. And each limit groove 232 is arc-shaped and is arranged coaxially with the guide disc 23. The number of the guide grooves 231 is preferably 3. The rear side of the central baffle 21 is correspondingly provided with a plurality of limiting columns 212. Each of the restraint posts 212 extends into the restraint slot 232, respectively. During rotation of the guide disc 23, the restraint posts 212 move relative to the restraint slots 232. When the guide disc 23 rotates to a certain extent, the stopper post 212 moves to the end of the stopper groove 232 and prevents the guide disc 23 from further rotating. The above-mentioned limit groove 232 is used to prevent the guide plate 23 from rotating excessively and the guide post 27 from disengaging from the guide plate 23.

In addition, a rear side guard 24 may be installed at the rear side of the guide plate 23 to cover the guide plate 23.

The rotating ring 33 is rotatable about its central axis. In this embodiment, the wind guiding structure 30 further includes a rotating ring motor 331 and a rotating ring gear disposed on an output shaft of the rotating ring motor 331, an arc-shaped rack is correspondingly disposed on an outer peripheral edge of the rotating ring 33, and the rotating ring gear is engaged with the arc-shaped rack to drive the rotating ring 33 to rotate. The inner peripheral surface of the rotating ring 33 is further opened with a plurality of circular holes 332, in this embodiment, the number of the circular holes 332 is 12, and the 12 circular holes 332 are symmetrically arranged by taking one diameter of the rotating ring 33 as an axis, that is, 6 circular holes 332 are respectively arranged on each side of the symmetry axis.
