[0032] This application provides a ceiling fan panel to solve the problem that the air outlet of the ceiling fan panel cannot be fully closed. The following description will be provided in conjunction with the accompanying drawings.

[0033] In the embodiments of this application, such as Figure 1 and Figure 2 As shown, the ceiling fan panel includes:

[0034] Base 1;

[0035] An air guide 2 is slidably connected to the inner side of the base 1. The air guide 2 is provided with a return air channel 211 extending along a first direction. The outer peripheral surface of the air guide 2 and at least a portion of the base 1 enclose an air outlet channel 4, with the air outlet side of the air outlet channel 4 located on the periphery of the air guide 2.

[0036] Drive component 3 is mounted on base 1;

[0037] Among them, the driving component 3 is used to drive the air guide component 2 to slide, so as to open or close the air outlet channel 4.

[0038] It should be noted that the working principle of the joist panel is as follows: indoor air is first drawn in through the return air duct 211, then exchanges heat with the joist's heat exchanger, and finally the air generated after heat exchange is discharged from the outlet air duct 4. Based on this, the description of the air guide 2 with the return air duct 211 and the outer peripheral surface of the air guide 2 implicitly discloses that the air guide 2 has a roughly annular structure. Furthermore, the air outlet side of the outlet air duct 4 being located on the periphery of the air guide 2 means that the airflow is blown out radially upward along the air guide 2, and the air guide 2 has a structure that prevents the airflow from blowing out axially; the first direction refers to the axial direction of the air guide 2. It is easy to imagine that the structure of the outlet air duct 4 near its own outlet side is annular, so that the joist panel can achieve 360-degree airflow without dead angles. "The driving component 3 is used to drive the air guide 2 to slide, so as to open or close the air outlet channel 4" means that: by using the structure on the air guide 2 that blocks the airflow from blowing upward along its own axis, when the driving component 3 drives the air guide 2 to slide on the base 1, the structure on the air guide 2 that blocks the airflow from blowing upward along its own axis moves closer to the base 1 until the air outlet channel 4 is completely closed; or, the structure on the air guide 2 that blocks the airflow from blowing upward along its own axis moves away from the base 1 to open the air outlet channel 4.

[0039] It is understandable that by setting up an air outlet channel 4 with the aforementioned characteristics and simultaneously moving the air guide 2 relative to the base 1, both the complete closure of the annular air outlet channel 4 and 360-degree air outlet without dead angles can be achieved in one go. In related technologies, even if air guide plates are set in the air outlets located at the four corners, additional transmission structures are required to achieve the closure of all air outlets at the same time, which is complex and increases production costs. In addition, in this embodiment, the air guide 2 can be controlled by the drive component 3 to adjust the size of the air outlet channel 4. When the air outlet channel 4 becomes smaller, the air pressure in the air outlet channel 4 is increased, thereby achieving the effect of long-distance air delivery.

[0040] For example, the sliding direction of the air guide 2 on the base 1 can be along a first direction; or the air guide 2 can rotate away from or towards the base 1.

[0041] In some embodiments, such as Figure 2 As shown, the base 1 is provided with a sliding groove 121, and there is an angle between the extension direction of the sliding groove 121 and the first direction. The air guide 2 is slidably connected in the sliding groove 121.

[0042] It should be noted that the angle between the extension direction of the slide groove 121 and the first direction is not equal to 0 degrees and not equal to 180 degrees. In conjunction with the above embodiment, "the driving member 3 is used to drive the air guide 2 to slide, so as to open or close the air outlet channel 4", it can be known that the angle between the extension direction of the slide groove 121 and the first direction is not equal to 90 degrees. When the driving member 3 drives the air guide 2 to slide in the slide groove 121, the air guide 2 can be rotated and moved along the first direction.

[0043] It is understandable that by providing a groove 121 with the aforementioned characteristics on the base 1, not only can the relative position between the air guide 2 and the base 1 be changed along the first direction, but the air guide 2 can also be rotated, changing the air guiding direction of the parts with different structures on the air guide 2. Compared to the air guide 2 only moving along the first direction, the groove 121 not only guides the direction of movement of the air guide 2, but also provides upward support for the air guide 2, sharing the weight of the air guide 2 borne by the drive component 3.

[0044] For example, the angle between the extension direction of the slide groove 121 and the first direction is greater than 0 degrees and less than 90 degrees, or greater than 90 degrees and less than 180 degrees. Specifically, the extension direction of the slide groove 121 can be spiral or S-shaped, etc.

[0045] In some embodiments, such as Figure 2 As shown, the slide groove 121 extends spirally around the first direction, and the base 1 is provided with multiple slide grooves 121.

[0046] It should be noted that the spiral extension of the chute 121 around the first direction means that the chute 121 is like a spiral line wrapped around the first direction. When the air guide 2 slides in the chute 121, it presents a state of rotating upward or optional downward.

[0047] Understandably, when the air guide 2 slides within the groove 121, it can change the air guiding direction of the different structural parts on the air guide 2. Furthermore, the groove 121 not only guides the movement direction of the air guide 2 but also provides upward support, sharing the weight of the air guide 2 borne by the drive component 3. Moreover, the drive component 3 only needs to provide driving force in the first direction and the direction opposite to the first direction, which simplifies the structure of the drive component 3.

[0048] In some embodiments, such as Figure 2 As shown, the air guide 2 includes a return air section 21 and an air guide section 22. The return air section 21 is slidably connected in the slide groove 121 and is provided with a return air channel 211. The air guide section 22 is sleeved on the return air section 21 and blocks the part of the air outlet channel 4 located between the base 1 and the return air section 21.

[0049] It should be noted that the air guide 22 changes the direction of the airflow from the base 1 by blocking the part of the air outlet channel 4 located between the base 1 and the return air section 21, so that the airflow flows out radially along the air guide 2, thus achieving annular air outlet.

[0050] It is understandable that, such as Figure 3 and Figure 4As shown, when the driving member 3 drives the air guide member 2 to slide on the base 1, the air guide 22 follows the return air section 21 and rotates upward until it comes into contact with the base 1 to close the air outlet channel 4; or, it rotates downward to move away from the base 1, thereby opening the air outlet channel 4.

[0051] Specifically, the drive unit 3 is disposed on the base 1, and the drive unit 3 is connected to the return air section 21 to drive the air guide 2 to slide.

[0052] In some embodiments, such as Figure 6 As shown, the air guide section 22 includes multiple fixed sections 222 and multiple movable sections 221; the multiple fixed sections 222 are arranged at intervals around the return air section 21 and block at least a portion of the air outlet duct 4 located between the base 1 and the return air section 21; each movable section 221 is movably connected between any two adjacent fixed sections 222.

[0053] It should be noted that, as the name suggests, the fixed part 222 refers to the structure fixedly connected to the return air part 21, and the fixed part 222 moves together with the return air part 21; the movable part 221 refers to the structure directly and movably connected to the fixed part 222, or indirectly and movably connected to the fixed part 222. The movable part 221 not only moves together with the return air part 21, but can also move relative to the fixed part 222. The movable part 221 being indirectly and movably connected to the fixed part 222 means that the movable part 221 is indirectly connected to the fixed part 222 through its connection to the return air part 21; and the movable part 221 is movably connected to the return air part 21.

[0054] Understandably, the air outlet range or direction of the air outlet duct 4 can be expanded or reduced by manually adjusting the position of the movable part 221 relative to the fixed part 222. When the air guide 2 rotates up or down, the position of the movable part 221 changes circumferentially in the first direction to provide different airflow sensations to different areas of the indoor space. The fixed part 222 can effectively isolate the return air area and the air outlet area of ​​the ceiling unit panel, preventing the exhaust air from being immediately drawn back, minimizing internal circulation within the ceiling unit panel, and ensuring indoor air supply and heat exchange efficiency.

[0055] For example, the movable connection between the movable part 221 and the fixed part 222 can be a sliding connection. Specifically, the movable part 221 is slidably connected to the fixed part 222 or the return air part 21 along the first direction; or, the movable part 221 is slidably connected to the return air part 21 radially; or, the movable part 221 is slidably connected to the fixed part 222 circumferentially. The movable connection between the movable part 221 and the fixed part 222 can also be a rotating connection. Specifically, both ends of the movable part 221 are rotatably connected to the two fixed parts 222 respectively, and the axis of rotation of the movable part 221 is perpendicular to the first direction, so that the side of the movable part 221 away from the return air part 21 can swing up and down. The movable part 221 and the fixed part 222 are designed according to the return air part 21 and the base 1 to better close the air outlet channel 4.

[0056] In some embodiments, such as Figure 2 As shown, the base 1 includes an outer frame 11, an inner frame 12, and a connecting bridge 13. The outer frame 11 is spaced outside the inner frame 12. The connecting bridge 13 connects the outer side of the outer frame 11 and the inner side of the inner frame 12. The inner side of the inner frame 12 is slidably connected to the air guide 2. The outer side of the outer frame 11, the inner side of the inner frame 12, and the connecting bridge 13 enclose at least a portion of the air outlet channel 4.

[0057] Understandably, while ensuring the smooth flow of air after heat exchange from between the outer frame 11 and the inner frame 12, the inner frame 12, which provides the installation position for the air guide 2, is fixed by the connecting bridge 13. This allows at least a portion of the air outlet channel 4 to be formed around the air guide 2, creating an annular air outlet channel 4. The remaining portion of the air outlet channel 4 is located between the outer frame 11, the inner frame 12, and the connecting bridge 13.

[0058] In some embodiments, such as Figure 2 and Figure 5 As shown, the driving component 3 includes a driver 31 and a gear set. The shaft of the gear set is parallel to the first direction. An internal gear ring 212 that meshes with the gear set is provided on the inner side of the air guide 2. The driver 31 is used to drive the gear set 32 ​​to rotate, so as to drive the air guide 2 to rotate.

[0059] It should be noted that "the shaft of the gear set is parallel to the first direction" means that the shafts of all the gears in the gear set are parallel to the first direction. The driver 31 can be a motor or other structure that can rotate the gear set.

[0060] Understandably, the meshing between the gear set and the internal gear ring 212 provides the air guide 2 with its circumferential driving force, while it rotates upward or downward under the guidance of the slide groove 121.

[0061] In some embodiments, such as Figure 5As shown, the gear set includes a drive gear 32 and a transmission gear 33. The drive gear 32 is coaxially connected to the driver 31, and the transmission gear 33 is rotatably connected to the base 1 and meshes with the drive gear 32. The rotation axes of the drive gear 32 and the transmission gear 33 are both parallel to the first direction. The module of the meshing part of the transmission gear 33 and the drive gear 32 is different from the module of the meshing part of the transmission gear 33 and the internal gear ring 212.

[0062] It should be noted that the module (m) is a fundamental parameter representing the size of gear teeth. It is the value obtained by dividing the pitch circle diameter (d) by the number of teeth (z), i.e., m = d / z. For example, if a gear has a pitch circle diameter of 60mm and 20 teeth, then its module m = 60 / 20 = 3mm. The module can be understood as the arc length occupied by each tooth on the pitch circle. The larger the module, the larger the teeth. The pitch circle is an artificially defined circle; when two gears have the same module and are correctly meshed, their pitch circles are tangent. The driver 31 can be a motor or other structure that enables the drive gear 32 to rotate.

[0063] It is understandable that the transmission gear 33 has gear rings with different parameters in the circumferential direction, and the transmission gear 33 has different modules for meshing with different structures. This can better match the transmission ratio with the drive gear 32 and the internal gear ring 212, improve the transmission efficiency, and at the same time improve the service life of the teeth of the transmission gear 33, the drive gear 32 and the internal gear ring 212, and prevent the occurrence of tooth shaving.

[0064] In some embodiments, such as Figure 5 As shown, the axial length of the meshing part of the transmission gear 33 and the drive gear 32 is greater than the axial length of the meshing part of the transmission gear 33 and the internal gear ring 212.

[0065] It should be noted that, since the internal gear ring 212 located on the air guide 2 will move in the first direction along with the air guide 2, the meshing part of the transmission gear 33 and the internal gear ring 212 not only includes the part that is currently meshing, but also the part that will mesh after the internal gear ring 212 moves with the air guide 2.

[0066] It is understandable that by extending the axial length of the meshing portion between the transmission gear 33 and the internal gear ring 212, the maximum range of movement of the air guide 2 in the first direction is increased.

[0067] For example, the drive gear 32, the transmission gear 33, and the internal gear ring 212 can be spur gears, helical gears, or herringbone gears.

[0068] This application also provides a ceiling fan, which includes the ceiling fan panel and a heat exchanger.

Since this ceiling fan 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, which will not be described in detail here.
