Detailed ways

An embodiment of the present invention provides a wall-mounted air conditioner indoor unit, which may include a housing 10 . At least one circular air outlet 11 is provided on the front surface of the casing 10 . For example, there may be multiple circular air outlets 11, preferably two, arranged in a row along the length direction of the indoor unit. The wall-mounted air conditioner indoor unit also includes an opening and closing structure 20 for the circular air outlet 11 . As shown in FIGS. 1 to 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 arranged at the center of the circular air outlet 11 , and an air outlet area is formed between its outer peripheral edge and the inner peripheral edge of the circular air outlet 11 . For example, the above-mentioned central baffle 21 may be circular, and the corresponding air outlet area is circular. In some alternative embodiments of the present invention, the above-mentioned central baffle 21 may be in other shapes such as square and ellipse.

A plurality of curved blades 22 are sequentially arranged along the circumference of the central baffle 21 , for example, the number of curved blades 22 may be 6, and are evenly arranged along the periphery of the central baffle 21 . In some other embodiments, the number of blades can be less than 6 or more than 6, which can be set according to the size of the blades, the size of the central baffle 21 and the size of the circular air outlet 11 . A plurality of curved blades 22 can be gathered toward the center of the central baffle 21 to at least partially open the wind outlet area, and can be completely gathered and shrunk to the front side or the rear side of the central baffle 21 . Preferably, it can be fully gathered and shrunk to the rear side of the central baffle 21, that is to say, when the plurality of curved blades 22 are in a fully retracted state, the central baffle 21 can cover the plurality of curved blades 22, and the user cannot view them from the air outlet. Curved blades 22 are observed externally, as shown in FIG. 2 . The plurality of curved blades 22 can also be deployed in a direction away from the center of the central baffle 21 to at least partially close the wind outlet area. As shown in FIG. 1 , a plurality of curved blades 22 can be deployed to completely cover the above-mentioned annular air outlet area, so as to fully close the air outlet.

5, 6 and 7 are schematic front view, top view and bottom view respectively of the curved blade 22 of the opening and closing structure 20 according to another embodiment of the present invention. As shown in FIGS. 5 to 7 , the curved blade 22 is approximately crescent-shaped and has an outer contour edge and an inner contour edge. The outer contour edge is convex and the inner contour edge is concave. The edge of the inner contour is set toward the center of the central baffle when a plurality of curved blades gather, and correspondingly, the edge of the outer contour can face the inner periphery of the circular air outlet when a plurality of curved blades gather, as shown in Figure 9 shown. The outer contour edge portion and the inner contour edge portion together define a root end and a tip end of the curved blade 22 .

As shown in FIGS. 5-7 , in some embodiments of the present invention, the outer contour edge of the curved blade 22 includes a first arcuate section 221 and a second arcuate section 222 . The inner contour edge comprises a third arcuate section 223 and a fourth arcuate section 224 . The first arc-shaped section 221 and the fourth arc-shaped section 224 gradually approach toward the root end of the curved blade 22 , so that the root end of the curved blade 22 forms a tapered curved area. The second arc-shaped section 222 and the third arc-shaped section 223 gradually approach toward the end of the curved blade 22 , so that the end of the curved blade 22 also forms a tapered curved area. That is to say, the first arc-shaped segment and the fourth arc-shaped segment approach gradually along the direction to the root end of the curved blade, so that the root end of the curved blade forms a tapered curved area. The second arc-shaped section and the third arc-shaped section gradually approach along the direction toward the end of the curved blade, so that the end of the curved blade forms a tapered curved area.

In some preferred embodiments of the present invention, the curvature of the first arc-shaped section 221 is equal to the curvature of the outer peripheral edge 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 , make the first arc-shaped sections 221 of the plurality of curved blades 22 coincide with the outer peripheral edge of the central baffle 21, as shown in FIG. 9 . And after the plurality of curved blades 22 are gathered, a partial area of each curved blade 22 is located between two adjacent curved blades 22 of the curved blade 22 . The curvature of the second arc-shaped section 222 is equal to the curvature of the inner peripheral edge of the air outlet, so that when the plurality of curved blades 22 are fully deployed to cover the wind outlet area, the second arc-shaped area of the plurality of curved blades 22 Section 222 coincides with the inner periphery of the air outlet, as shown in FIG. 8 . With such a design, the plurality of curved blades 22 can be fully folded to the rear side of the central baffle 21 or fully unfolded to cover the air outlet area, making the shape of the air outlet more complete and beautiful.

In addition, the curvature and length of the third arc-shaped section 223 are equal to the curvature and length of the first arc-shaped section 221 . In this embodiment, when a plurality of curved blades 22 are fully deployed to cover the wind outlet area, as shown in FIG. The curved sections are just put together so that a plurality of curved blades 22 can completely cover the wind outlet area, and at the same time, there is no overlapping as much as possible between adjacent curved blades 22, so as to make full use of the size of the curved blades, so that the outlet The shape of the tuyere is more complete and beautiful.

In some embodiments of the present invention, in order to facilitate gathering and unfolding of multiple curved blades, each curved blade is preferably rotatably disposed around its root end on the front side or rear side of the central baffle. For example, as shown in FIG. 8 and FIG. 9 , each curved blade can rotate around its root end to the rear side of the central baffle, and multiple curved blades are stacked in sequence.

Further, the first arc-shaped section 221 also has a guide 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 that when the plurality of curved blades 22 contract or expand, the The plurality of curved blades 22 are guided in the front and rear directions of the indoor unit, so that the plurality of curved blades 22 can at least partially overlap. Specifically, after a plurality of curved blades gather together, in every two adjacent curved blades 22, the partial area of the end of one curved blade 22 is located at the rear side of the partial area of the root end of the other curved blade 22, And the first arc-shaped section of each curved blade has a guide flange that protrudes toward the rear side of the curved blade and gradually rises from the root end adjacent to the curved blade toward the direction away from the root end. Or, after a plurality of curved blades gather together, in every two adjacent curved blades 22, the partial area of the end of one curved blade 22 is located at the front side of the partial area of the root end of the other curved blade 22, and The first arc-shaped section of each curved blade has a guide flange that protrudes toward the front side of the curved blade and gradually rises from the root end adjacent to the curved blade toward the direction away from the root end.

This arrangement is because the adjacent curved blades 22 may interfere mechanically during the process of the plurality of curved blades 22 being folded together. The position of the above-mentioned guide flange 225 near the root end is lower, and the position away from the root end is higher. When the adjacent curved blades 22 are folded to overlap each other, the guide flange 225 can guide the adjacent blades to move slightly towards the rear side, so that Adjacent curved blades 22 are staggered in the front-back direction of the opening and closing structure 20 to prevent mechanical interference.

In some embodiments of the present invention, the root end of the curved blade 22 is provided with a blade shaft 26, and the curved blade 22 is pivotally connected to the position adjacent to the edge of the rear side of the central baffle 21 through the blade shaft 26, so that the curved Shaped blade 22 can rotate bidirectionally around blade rotating shaft 26. A plurality of curved blades 22 are unfolded or gathered by rotating around the above-mentioned blade rotating shaft 26 . As shown in Figures 8 and 9, when a plurality of curved blades 22 rotate clockwise around the blade shaft 26 from the state of Figure 8 (observed by the observer from the rear side of the wall-mounted air conditioner indoor unit to the front side), Then it is drawn toward the central baffle plate 21 to the position state shown in FIG. 9 . When the plurality of curved blades 22 rotate counterclockwise around the blade shaft 26 from the state shown in FIG. 9 , they will rotate and expand toward the edge of the air outlet, and can return to the position state shown in FIG. 8 .

In some embodiments of the present invention, the opening and closing structure 20 further includes a curved blade driving mechanism. The curved blade driving mechanism is used to drive each curved blade 22 to rotate along its blade rotating shaft 26 to open or close the air outlet area. For example, in some optional embodiments, the curved blade driving mechanism may be a plurality of link mechanisms and a stepper motor connected to the plurality of link mechanisms, each link mechanism is connected to a corresponding curved blade 22 . The stepper motor drives the curved blade 22 to rotate through the link mechanism.

As shown in Figure 10 and Figure 11 (need special explanation, in order to more clearly show the operating principle of the curved blade 22 driving mechanism, only a single curved blade 22 is shown in Figure 10 and Figure 11), in the present invention In some preferred embodiments, the above-mentioned curved blade driving mechanism may include a guide disc 23 . The guide disc 23 is circular and is arranged on the rear side of the central baffle 21. Its center coincides with the center of the central baffle 21 and can rotate bidirectionally around a straight line perpendicular to its own plane and passing through its own center. The central axis rotates along a first direction, and can also rotate around its central axis along a second direction opposite to the first direction.

Further, the rear surface of the guide plate 23 is provided with a plurality of curved guide grooves 231 extending from the middle portion (also referred to as the middle area, central area) of the guide plate 23 to the edge. The number of curved guide grooves 231 is the same as the number of curved blades 22 , and each curved guide groove 231 cooperates with a corresponding curved blade 22 . For example, each curved blade further includes a guide post 27 , one end of the guide post 27 can be fixed on the rear side of the curved blade 22 , and the other end is snapped into the corresponding curved guide groove 231 . That is to say, each curved guide groove is used for accommodating a guide column, so that when the guide coil rotates bidirectionally around its central axis, the guide column is forced to move along the curved guide groove, thereby driving the corresponding curved blade to rotate.

In some preferred embodiments of the present invention, the guide post 27 can be arranged on the edge of the inner contour of the curved blade 22 , and the guide post 27 is perpendicular to the plane where the guide disc 23 is located. Preferably, the guide post 27 can be located on the guide post fixing section between the third arc-shaped section 223 and the fourth arc-shaped section 224 , and the guide post 27 and the blade rotating shaft 26 protrude in the same direction. Moreover, the distance from a point on the guide groove 231 to the corresponding blade rotating shaft 26 of the curved blade 22 gradually increases along the radial direction of the guide disc 23 . That is to say, the distance from the point of the guide groove 231 near the edge of the guide plate 23 to the blade rotation axis 26 is greater than the distance from the point near the center of the guide plate 23 to the blade rotation axis 26 .

In actual use, as shown in FIG. 10 , the curved blade 22 is in a fully unfolded state at this time, and the guide post 27 is located in the guide groove 231 near the edge of the guide disc 23 . When the curved blade 22 needs to be folded in, the drive guide disc 23 rotates clockwise, the distance from the curved guide groove 231 to the blade shaft 26 corresponding to the curved blade 22 increases, and the guide column 27 is forced to move toward the guide disc along the curved guide groove 231 The central position of 23 slides, and drives curved blade 22 to rotate toward the central direction of central baffle 21 and gathers, as shown in FIG. 11 . When the guide column 27 moves to the end of the curved guide groove 231 close to the center of the guide disc 23 , the curved vane 22 is completely retracted to the rear side of the central baffle 21 . When the curved blade 22 needs to be deployed, the driving guide disc 23 rotates counterclockwise, the distance from the curved guide groove 231 to the corresponding curved blade 22 blade shaft 26 decreases, and the guide post 27 is forced to guide along the curved guide groove 231 The edge position of the disk 23 slides, and drives the curved blade 22 to rotate and expand toward the edge of the circular air outlet 11 . When the guide column 27 moves to the end of the curved guide groove 231 close to the edge of the guide plate 23, the curved blade 22 is fully expanded to close the air outlet area.

In some embodiments of the present invention, in order to facilitate the rotation of the guide disc 23 , the middle part of the guide disc 23 also has a circular opening 233 , and a ring gear is arranged around the inner side of the circular opening 233 . The above-mentioned curved blade driving mechanism may also include a guide disc gear and a guide disc motor 25 . The guide disc gear is arranged in the circular opening 233 of the guide disc 23 , and meshes with the ring gear inside the circular opening 233 . The guide disc motor 25 is used to drive the guide disc gear to rotate, and then drives the guide disc 23 to rotate. The steering wheel motor 25 may be a rotary motor.

In some embodiments of the present invention, further, in order to make the guide plate 23 not deviate from the track during the rotation process, the edge of the central baffle plate 21 can be provided with a flange protruding backwards, and the guide plate 23 is located in the area where the flange is located. Turn inside. Preferably, a plurality of rotating shaft fixing pieces 211 protruding toward the center of the guide plate 23 can also be provided on the periphery of the above-mentioned flange. On the one hand, the rotating shaft fixing piece 211 can be used to set the blade rotating shaft 26 of the curved blade 22 , and on the other hand, it can also limit the movement track of the guide plate 23 in the front-rear direction.

In some embodiments of the present invention, the guide plate 23 is further provided with a plurality of limiting grooves 232 arranged at intervals along a concentric circle on the guide plate 23 . Moreover, each limiting slot 232 is arc-shaped and coaxially arranged with the guide plate 23 . The number of the above-mentioned guide grooves 231 is preferably three. The rear side of the central baffle 21 is correspondingly provided with a plurality of limiting posts 212 . Each of the aforementioned limiting columns 212 extends into the limiting groove 232 accordingly. During the rotation of the guide disc 23 , the limiting column 212 moves relative to the limiting groove 232 . When the guide plate 23 rotates to a certain degree, the limiting column 212 moves to the end of the limit groove 232 and prevents the guide plate 23 from further rotating. The limiting groove 232 is used to prevent the guide plate 23 from over-rotating, and the guide post 27 is separated from the guide plate 23 .

In addition, a rear side baffle 24 can also be installed on the rear side of the guide disc 23 for covering the guide disc 23 .
