[0002] In related technologies, some ceiling-mounted air conditioners are equipped with air guide structures that can swing to direct airflow in different directions. However, these air guide structures are relatively complex and have low reliability, thus failing to adequately meet airflow requirements. Utility Model Content

[0003] This application provides a ceiling-mounted air conditioner and its panel structure, which can simplify the air guiding structure, improve the reliability of movement, and better meet the air guiding requirements.

The rotating member is rotatably mounted on the panel assembly about a vertical axis, so as to drive the air guide plate to pitch and rotate about the horizontal axis between a first angle and a second angle via the connecting rod. The air guide plate guides the airflow from the panel assembly at the first angle so that at least a portion of the airflow is blown outward at an angle downward, and avoids the airflow from the panel assembly at the second angle so that the airflow is blown outward in a horizontal direction.

[0005] In some embodiments, the driving mechanism further includes a driving member and a transmission gear, the driving member being used to drive the transmission gear to rotate; the rotating member is provided with a meshing portion, the meshing portion meshing with the transmission gear.

[0007] In some embodiments, the panel assembly includes a panel base and a decorative panel. The panel base is provided with an air outlet. The decorative panel is movably disposed on the panel base to open or close the air outlet. The air guide plate is rotatably connected to the decorative panel about the horizontal axis. The drive mechanism is disposed on the decorative panel. When the decorative panel opens the air outlet and the air guide plate rotates to the second angle, the decorative panel causes the airflow from the air outlet to blow outward in the horizontal direction.

[0008] In some embodiments, the decorative panel has a mounting groove on its air guide surface, and the air guide plate can extend out of the mounting groove or be embedded in the mounting groove rotatably around the horizontal axis; when the air guide plate rotates to the first angle, the air guide plate extends out of the mounting groove to guide the airflow of the panel assembly; when the air guide plate rotates to the second angle, the air guide plate is embedded in the mounting groove to avoid the airflow of the panel assembly.

[0009] In some embodiments, the decorative panel is installed at the air outlet and can be raised and lowered to open or close the air outlet.

[0010] In some embodiments, the decorative panel includes a panel body and a guide flange. The guide flange is formed on the outer peripheral surface of the panel body. The panel body is slidably disposed at the air outlet in the vertical direction so that the guide flange can open or close the air outlet. The guide plate is disposed on the side of the guide flange facing the panel base. When the guide flange opens the air outlet and the guide plate rotates to the second angle, the guide flange and the panel base are spaced apart so that the airflow from the air outlet is blown outward in the horizontal direction.

[0014] This embodiment of the application sets up a panel assembly, an air guide plate, and a drive mechanism. The air guide plate is driven to pitch and rotate around a horizontal axis between a first angle and a second angle by the rotating component and connecting rod in the drive mechanism. The air guide plate guides the airflow from the panel assembly at the first angle so that at least part of the airflow is blown outward at an angle downward. The air guide plate avoids the airflow from the panel assembly at the second angle so that the airflow is blown outward in a horizontal direction, thus meeting the airflow guidance requirements of different heat exchange modes and different angles.

The following description is provided to enable any person skilled in the art to make and use this application. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that this application can be made without using these specific details. In other instances, well-known structures and processes are not described in detail to avoid obscuring the description of this application with unnecessary detail. Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0027] like Figures 1 to 4 As shown, on the one hand, this application provides a ceiling machine panel structure 1, which includes a panel assembly 10, an air guide plate 20 and a drive mechanism, which can simplify the air guide structure, improve the reliability of movement and better meet the air guide requirements.

[0028] The panel assembly 10 can dissipate air horizontally. Here, the panel assembly 10 can switch between an open state and a closed state; in the open state, it dissipates air horizontally, while in the closed state, it stops dissipating air. An air guide plate 20 is disposed on the panel assembly 10 and is rotatably connected to the panel assembly 10 about a horizontal axis, thereby rotatably changing the angle between the air guide plate 20 and the panel assembly 10. For example, the air guide plate 20 can be hinged to the panel assembly 10 via a first hinge portion 21, the central axis of which lies in the horizontal plane.

[0029] The drive mechanism includes a rotating member 31 and a connecting rod 32. Both ends of the connecting rod 32 are hinged to the rotating member 31 and the air guide plate 20, respectively. The rotating member 31 is rotatably mounted on the panel assembly 10 about a vertical axis, driving the air guide plate 20 to pitch between a first angle and a second angle about a horizontal axis via the connecting rod 32. Here, when the rotating member 31 rotates about the vertical axis, it applies a force to the connecting rod 32 and the air guide plate 20, causing them to tend to rotate synchronously with the rotating member 31. The end of the connecting rod 32 connected to the rotating member 31 rotates synchronously with the rotating member 31. The panel assembly 10, based on the rotational connection, applies a constraint force to the air guide plate 20, preventing the air guide plate 20 and the connecting rod 32 from rotating synchronously with the rotating member 31 along with the end connected to the air guide plate 20. In this way, the two ends of the connecting rod 32 have asynchronous movement tendencies, which causes the distance between the two ends of the connecting rod 32 to increase or decrease, thereby forcing the end of the connecting rod 32 connected to the air guide plate 20 to rise or fall. When rising, the air guide plate 20 is rotated to the first angle, and when falling, the air guide plate 20 is rotated to the second angle, thereby achieving the purpose of driving the pitch rotation of the air guide plate 20.

[0030] When the air guide plate 20 rotates to the first angle, it guides the airflow from the panel assembly 10, causing at least a portion of the airflow to be blown outwards at an angle downwards. At this time, if the ceiling unit is in heating mode, the warm air blown out by the panel assembly 10, guided by the air guide plate 20, can be blown outwards at an angle downwards, allowing the warm air to be quickly delivered to the area where the person is located, rapidly increasing the temperature and comfort of that area. When the air guide plate 20 rotates to the second angle, it avoids directing the airflow from the panel assembly 10, causing the airflow to be blown outwards horizontally. At this time, if the ceiling unit is in cooling mode, because the air guide plate 20 avoids directing the airflow from the panel assembly 10, the cold air blown out by the panel assembly 10 can be blown outwards horizontally, preventing the cold air from blowing directly onto the area where the person is located, rapidly increasing the temperature and comfort of that area.

[0031] Compared with related technologies, the ceiling-mounted air conditioning panel structure 1 provided in this application embodiment, by setting up a panel assembly 10, an air guide plate 20 and a driving mechanism, uses the rotating part 31 and the connecting rod 32 in the driving mechanism to drive the air guide plate 20 to pitch and rotate around the horizontal axis between a first angle and a second angle. The air guide plate 20 guides the airflow of the panel assembly 10 at the first angle so that at least part of the airflow is blown outward at an angle downward, and the air guide plate 20 avoids the airflow of the panel assembly 10 at the second angle so that the airflow is blown outward in a horizontal direction, thus meeting the airflow guidance requirements of different heat exchange modes and different angles. The structure of the above-mentioned ceiling-mounted air conditioning panel structure 1 is relatively simple, which can improve the reliability of movement and make the airflow guidance movement more flexible and reliable.

[0032] The structure of the panel assembly 10 can be determined according to actual needs, and this application embodiment does not limit it. In some embodiments, the panel assembly 10 may include a panel base and a decorative panel 12. An air outlet 111 may be provided on the panel base, and the decorative panel 12 is movably disposed on the panel base to open or close the air outlet 111. The air guide plate 20 may be rotatably connected to the decorative panel 12 about a horizontal axis, and a drive mechanism may be disposed on the decorative panel 12. When the decorative panel 12 opens the air outlet 111 and the air guide plate 20 rotates to a second angle, the decorative panel 12 causes the airflow from the air outlet 111 to blow outward in a horizontal direction.

[0033] In some examples, the air guide surface of the decorative panel 12 may be provided with a mounting groove 1221, and the air guide plate 20 may extend out of or be embedded in the mounting groove 1221, rotatably about a horizontal axis. When the air guide plate 20 rotates to a first angle, it extends out of the mounting groove 1221 to guide the airflow from the panel assembly 10. When the air guide plate 20 rotates to a second angle, it is embedded in the mounting groove 1221 to avoid the airflow from the panel assembly 10. By providing the mounting groove 1221, the air guide plate 20 can extend outward to guide airflow by pitching and rotating about a horizontal axis, or be hidden inward to avoid airflow, reliably achieving the switching of airflow direction.

[0034] In some examples, the decorative panel 12 can be installed at the air outlet 111 and can be raised and lowered to open or close the air outlet 111. In other words, the decorative panel 12 can slide upward to approach and cover the panel base to close the air outlet 111, or slide downward away from the panel base to open the air outlet 111, reliably realizing the switching of the air outlet 111.

[0035] The structure of the decorative panel 12 can be determined according to actual needs, and this application embodiment does not limit it. In some examples, the decorative panel 12 may include a panel body 121 and a guide flange 122, which may be formed on the outer peripheral surface of the panel body 121. The panel body 121 is slidably disposed at the air outlet 111 in the vertical direction, so that the guide flange 122 opens or closes the air outlet 111. When the guide flange 122 opens the air outlet 111 and the guide plate 20 rotates to the second angle, the guide flange 122 and the panel base are spaced apart, so that the airflow from the air outlet 111 is blown outward in the horizontal direction. For example, the guide plate 20 may be disposed on the side of the guide flange 122 facing the panel base; the guide surface of the decorative panel 12 may be provided with a mounting groove 1221, which is located on the side of the guide flange 122 facing the panel base. For example, the air guide flange 122 may be an air guide ring with an annular structure.

[0036] In some embodiments, the drive mechanism may further include a drive member 33 and a transmission gear 34. The drive member 33 is used to drive the transmission gear 34 to rotate. The type of drive member 33 can be determined according to actual needs, and may be, for example, a drive motor, a hydraulic rotary motor, etc., which is not limited in this embodiment. The rotating member 31 is provided with a meshing part 311, which meshes with the transmission gear 34, so that a gear transmission relationship is formed between the rotating member 31 and the transmission gear 34. During operation, the drive member 33 drives the transmission gear 34 to rotate, and the transmission gear 34 then drives the rotating member 31 to rotate around the vertical axis based on the gear transmission relationship. The rotating member 31 then drives the air guide plate 20 to pitch around the horizontal axis through the connecting rod 32.

[0037] The structure of the rotating component 31 can be determined according to actual needs, and this application embodiment does not limit it. In some embodiments, the rotating component 31 can be a ring-shaped component, which extends around a vertical axis in a circumferential direction. The ceiling panel structure 1 may include multiple air guide plates 20 and multiple connecting rods 32. The multiple connecting rods 32 and multiple air guide plates 20 are arranged sequentially along the circumference of the rotating component 31. The number of multiple air guide plates 20 and multiple connecting rods 32 are equal and they are hinged one-to-one. Each air guide plate 20 rotates around a different horizontal axis when pitching. In other words, multiple air guide plates 20 can be arranged sequentially on each side of the panel assembly 10 along the circumference of the rotating component 31. The rotating component 31 can drive multiple air guide plates 20 to pitch and rotate synchronously around their respective horizontal axes through multiple connecting rods 32, thereby using multiple air guide plates 20 to guide or avoid the airflow in each side area of ​​the panel assembly 10, and realize the directional control of the surrounding airflow. In some examples, the drive mechanism may include the drive member 33 and the transmission gear 34 as described above, and the rotating member 31 may be a gear ring, which may be provided with a meshing part 311, and the meshing part 311 meshes with the transmission gear 34.

[0038] In some embodiments, the two ends of the connecting rod 32 can be hinged to the rotating member 31 and the air guide plate 20 respectively via ball hinges 35. By hinged to the connecting rod 32, rotating member 31, and air guide plate 20 via ball hinges 35, spherical contact can be achieved between the connecting rod 32 and rotating member 31, and between the connecting rod 32 and air guide plate 20. This allows for rotational connections between the connecting rod 32 and rotating member 31 around three rotation axes, and between the connecting rod 32 and air guide plate 20 around three rotation axes, thereby increasing the mobility of the connecting rod 32 and enabling the rotating member 31 to reliably drive the air guide plate 20 to pitch around a horizontal axis via the connecting rod 32.

[0039] In some embodiments, a support bearing 40 may be provided between the rotating member 31 and the panel assembly 10 to achieve a reliable support connection between the rotating member 31 and the panel assembly 10. A rotation guide groove 312 may be provided on one of the rotating member 31 and the panel assembly 10, and at least one support bearing 40 is disposed within the rotation guide groove 312 and on the other of the rotating member 31 and the panel assembly 10. The rotation guide groove 312 is used to limit the relative rotational stroke of the rotating member 31 and the panel assembly 10, allowing the rotating member 31 to rotate between the opposite sidewalls along the rotation direction of the rotating member 31 in the rotation guide groove 312, thus preventing excessive rotation of the rotating member 31 and damage to the air guide plate 20.

[0040] On the other hand, this application provides a ceiling-mounted air conditioner, which includes the ceiling-mounted air conditioner panel structure 1 of any of the above embodiments. The ceiling-mounted air conditioner with the above-described ceiling-mounted air conditioner panel structure 1 simplifies the airflow structure, improves operational reliability, and better meets airflow requirements.

Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
