[0039] As a hidden air conditioner, duct air conditioner is usually hidden in the ceiling and discharges air through a grille-type air outlet panel covering the ceiling air outlet.

[0040] In the related art, the air outlet panel is generally connected or snapped onto the air outlet of the ceiling using a connecting structural member.

[0041] However, during the long-term use of the air conditioner, the inside of the ceiling needs to be cleaned regularly to ensure the stable operation of the air conditioner. In addition, when the air conditioner fails to operate, it needs to be repaired. During the air conditioner maintenance process such as cleaning and repair, the staff needs to climb up to remove the air outlet panel. The disassembly and assembly process of the air outlet panel is cumbersome, making the maintenance of the air conditioner more difficult.

[0042] In view of the above problems, the present invention provides an automatic opening and closing device for an air outlet panel and an air conditioner, which can conveniently realize the opening and closing of the air outlet panel, thereby improving the convenience of air conditioner maintenance.

[0043] The following combination Figure 1-Figure 3 The utility model describes an automatic opening and closing device for an air outlet panel and an air conditioner.

[0044] Reference Figures 1 to 3 , an automatic opening and closing device for an air outlet panel, used to drive the opening and closing of the air outlet panel 20 covering the air outlet of the suspended ceiling 10, the lower side of the air outlet panel 20 is hinged to the suspended ceiling 10; the automatic opening and closing device includes a frame 30, a push-pull mechanism 31, a reeling and unreeling mechanism 32 and a rope 33; wherein, the frame 30 constitutes the support and installation base of the entire device, and is suitable for being connected to the inside of the suspended ceiling 10, one end of the frame 30 is the first end, when the frame 30 is installed in the suspended ceiling 10, the first end of the frame 30 faces the air outlet; the push-pull mechanism 31 is connected to the frame 30, which includes a driving member and a movable part that can move toward or away from the first end under the drive of the driving member; the reeling and unreeling mechanism 32 is connected to the movable part of the push-pull mechanism 31 and can move with the movable part; the rope 33 is reeled in the reeling and unreeling mechanism 32, and the free end of the rope 33 extends out of the first end for connecting to the air outlet panel 20 and the connection point is located above the hinge axis between the air outlet panel 20 and the suspended ceiling 10.

[0045] The air outlet panel 20 is automatically opened and closed by the push-pull mechanism 31 and the reel 32, and the air outlet panel 20 is automatically opened and closed by the push-pull mechanism 31. Compared with the related art, the air outlet panel 20 can be opened and closed conveniently, thereby improving the convenience of air conditioner maintenance.

[0046] For ease of control, refer to Figure 2 and Figure 3 The automatic opening and closing device for the air outlet panel also includes a first sensor 34, a second sensor 35 and a controller; wherein the first sensor 34 is adapted to generate a first signal when the movable part pushes the air outlet panel 20 to separate from the air outlet; the second sensor 35 is adapted to generate a second signal when the movable part pulls the air outlet panel 20 to move to a preset position; the controller is communicatively connected with the first sensor 34 and the second sensor 35, and when the controller receives the first signal, it controls the retracting and unreeling mechanism 32 to unreel the rope 33, and when the controller receives the second signal, it controls the retracting and unreeling mechanism 32 to reel the rope 33.

[0047] During specific application, when the air outlet panel 20 needs to be opened, the movable end of the push-pull mechanism 31 moves toward the direction close to the air outlet panel 20 and pushes the air outlet panel 20 out from the air outlet, and the air outlet panel 20 is separated from the air outlet. The first sensor 34 generates a first signal, and the controller controls the reeling mechanism 32 to unwind the rope 33 based on the first signal until the air outlet panel 20 is opened to a preset state; when the air outlet panel 20 needs to be closed, the movable end of the push-pull mechanism 31 moves toward the direction away from the air outlet panel 20. When the air outlet panel 20 is pulled up to the preset position, the second sensor 35 generates a second signal, and the controller controls the reeling mechanism 32 to unwind based on the second signal until the air outlet panel 20 is closed to a preset state.

[0048] According to different working principles, there are multiple selectable types of the first sensor 34 and the second sensor 35, which can be flexibly configured according to actual needs.

[0049] Specifically, in an embodiment of the present invention, the first sensor 34 is configured as a contact sensor, which is connected to the end of the movable part close to the first end, or connected to the position of the air outlet panel 20 corresponding to the end of the movable part. When the air outlet panel 20 is closed, the end of the air outlet panel 20 or the movable part contacts the first sensor 34, so that when the movable part pushes the air outlet panel 20 out of the air outlet, the contact sensor separates from the air outlet panel 20 and generates a first signal.

[0050] The other end of the frame 30 is the second end, and the second sensor 35 is configured as a position pressure sensor, which is connected to the end of the movable part away from the first end, or connected to the position of the second end of the frame 30 corresponding to the end of the movable part, so that when the movable part pulls the air outlet panel 20 to move to the preset position, the end of the movable part or the second end of the frame 30 contacts the position pressure sensor, and the position pressure sensor generates a second signal to control the push-pull mechanism 31 to stop moving, and the retractor 32 is retracted until the air outlet panel 20 is closed to the preset state.

[0051] The specific structures of the frame 30, the push-pull mechanism 31 and the retracting and unreeling mechanism 32 will be described in detail below with reference to the accompanying drawings.

[0052] Reference Figure 2 and Figure 3 The frame 30 specifically includes a shell 300 and a base 301; wherein the shell 300 is roughly U-shaped, and one end thereof is provided with an opening to form the first end of the frame 30, and the other end opposite is closed to form the second end of the frame 30. The U-shaped inner cavity of the shell 300 provides an installation space for the push-pull mechanism 31 and the retracting and unwinding mechanism 32; the base 301 is L-shaped, and one side of it is connected to the shell 300. Specifically, the two can be welded, or formed as one piece, or connected by bolts and other components. A connecting hole is provided on the other side to facilitate connection to the ceiling 10.

[0053] The movable portion of the push-pull mechanism 31 includes a sliding bracket 310 and a support plate 311. The sliding bracket 310 is slidably connected to the frame 30 and can slide toward or away from the first end of the frame 30. The driving member is in driving connection with the sliding bracket 310. The support plate 311 is connected to the end of the sliding bracket 310 facing the first end. When the air outlet panel 20 needs to be opened, the sliding bracket 310 slides toward the air outlet panel 20, and the support plate 311 pushes the air outlet panel 20 out of the air outlet. The first sensor 34 is connected to the end of the support plate 311 facing away from the sliding bracket 310.

[0054] In order to ensure that the movable part can slide stably and smoothly, refer to Figure 2 and Figure 3Guide rails 302 are arranged on both sides of the frame 30. Specifically, the guide rails 302 are arranged on the shell wall of the housing 300 and extend along the sliding direction of the sliding bracket 310. Guide portions 312 are provided on both sides of the support plate 311, and the guide portions 312 engage with the guide rails 302. The interlocking guide rails 302 and guide portions 312 can constrain and guide the sliding of the support plate 311, thereby improving the stability and smoothness of the sliding of the movable part.

[0055] The cross-section of the guide rail 302 is U-shaped, and the guide part 312 can be configured as a slider or a roller. It can be flexibly configured according to actual needs. In this embodiment, the guide part 312 is configured as a roller, and the roller and the guide rail 302 roll together. In this way, the resistance between the guide rail 302 and the guide part 312 is rolling friction, which can further improve the smoothness of the sliding of the movable part.

[0056] To further ensure the stability of the sliding movement of the movable portion, a support rod 313 is connected to the frame 30. The length of the support rod 313 is perpendicular to the sliding direction of the sliding bracket 310. The sliding bracket 310 is slidably supported on the support rod 313. Specifically, the two ends of the support rod 313 are fixedly connected to the two sides of the housing 300. The sliding bracket 310 is provided with a guide groove arranged along the sliding direction of the sliding bracket 310, giving the sliding bracket 310 an overall U-shaped structure. The support rod 313 is inserted into the guide groove. The support rod 313 supports the sliding bracket 310, ensuring its sliding stability.

[0057] In order to realize the driving of the movable part, in a specific embodiment of the present invention, the driving part includes a first motor 314 and a connecting rod assembly 315; wherein, the connecting rod assembly 315 includes two hinged groups of connecting rods, and the two groups of connecting rods can rotate around the hinge point and move closer to or away from each other; one group of connecting rods is connected to the frame 30, and the other group of connecting rods is connected to the movable part; the first motor 314 is connected to the hinge point of the connecting rod assembly 315 for driving the two groups of connecting rods to move closer to or away from each other.

[0058] Specifically, each group of connecting rods includes two connecting rod units with hinged ends, and the hinge point of the two connecting rod units in each group of connecting rods is the first hinge point. The two groups of connecting rods are hinged at the head and tail through the second hinge point, so that the connecting rod assembly 315 is formed as a quadrilateral structure as a whole; the first hinge points of the two groups of connecting rods are arranged along the sliding direction of the movable part, one group of connecting rods is hinged to the support rod 313, and the other group of connecting rods is hinged to the sliding bracket 310. When the two groups of connecting rods move around the second hinge point, the distance between the two first hinge points can change along the sliding direction of the movable part, thereby driving the movable part to move; the first motor 314 is connected to the second hinge point for driving the two groups of connecting rods to extend or contract around the second hinge point. Specifically, the first motor 314 and the second hinge point of the two groups of connecting rods are driven by the gear box 316.

[0059] Specifically, the connecting rod assembly 315 is located in the support groove of the sliding bracket 310, and one of the two sets of connecting rods is relatively close to the support rod 313 and is hinged to the support rod 313, while the first hinge point of the other set of connecting rods is hinged to the sliding bracket 310. In this way, when the first motor 314 drives the two sets of connecting rods to retract, it can pull the sliding bracket 310 in a direction close to the support rod 313, causing the entire movable part to move toward the first end close to the frame 30; when the first motor 314 drives the two sets of connecting rods to extend, it can push the sliding bracket 310 in a direction away from the support rod 313, causing the entire movable part to move toward the first end away from the frame 30, thereby achieving reciprocating sliding of the movable part.

[0060] It is understandable that the driving member includes but is not limited to the forms or structures listed above. Driving members of other structures or forms are also applicable as long as they can drive the movable part to move back and forth towards or away from the first end of the frame 30.

[0061] Reference Figure 3 The reeling and unreeling mechanism 32 includes a second motor 320, which is fixedly connected to the sliding bracket 310; the second motor 320 is transmission-connected to a reeling shaft. Specifically, the output shaft of the second motor 320 can be used as the above-mentioned reeling shaft, or a reeling rod can be connected to the output shaft of the second motor 320 as the reeling shaft. The end of the rope 33 is connected to the reeling shaft, and the reeling shaft is driven to rotate by the second motor 320 to realize the reeling and unreeling of the rope 33.

[0062] Specifically, the sliding bracket 316 is provided with a accommodating cavity and a rope outlet connected to the accommodating cavity and facing the first end of the frame body 30. The winding shaft is located in the accommodating cavity, and the rope 33 extends from the rope outlet. The accommodating cavity can store the wound rope 33, and the rope outlet can restrain and guide the rope 33 to ensure that the rope 33 is stably and smoothly retracted and released.
