[0032] This application provides a ceiling fan panel to solve the problem of dead airflow in ceiling fans. 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] The air guide 1 is provided with a through first return air inlet 111; and,

[0035] The base frame 2 is located on one side of the air guide 1. The base frame 2 is provided with a second return air inlet 222 that communicates with the first return air inlet 111 and a rectifier air duct 23 located around the second return air inlet 222.

[0036] Among them, the air guide 1 is provided with an exhaust duct 121 in the circumferential direction. The exhaust duct 121 is located on the outside of the base frame 2 and is connected to the rectifier duct 23.

[0037] It should be noted that the exhaust duct 121 circumferentially arranged on the guide member 1 means that the exhaust duct 121 extends and runs through the guide member 1 circumferentially. This exhaust duct 121 can be circular or square, with a circular shape being preferred. The first return air inlet 111 means that indoor return air can pass through the guide member 1 via the first return air inlet 111 and then flow to the ceiling unit for heat exchange via the second return air inlet 222. The rectifier duct 23 located around the second return air inlet 222 means that since the ceiling unit is usually installed horizontally on the ceiling, the horizontal direction of the second return air inlet 222 is its periphery. The outer side of the base frame 2 refers to the side of the base frame 2 facing the indoor space, and the corresponding side facing the ceiling unit heat exchanger, i.e., the inner side. The working principle of the ceiling air conditioner is as follows: After the indoor return air enters through the first return air inlet 111 and the second return air inlet 222, it exchanges heat with the heat exchanger of the ceiling air conditioner, and then is discharged into the room through the rectifier air duct 23 and the exhaust air duct 121 in sequence.

[0038] Understandably, because the base frame 2 needs to ensure the connection of its own structure, the rectifier duct 23 located on the base frame 2 cannot be designed to run through the second return air inlet 222 circumferentially and simultaneously through the return air direction of the second return air inlet 222. Therefore, by setting the guide 1 on the base frame 2, an annular exhaust duct 121 can be set circumferentially on the guide 1. When the airflow blows through the rectifier duct 23 towards the exhaust duct 121, the exhaust duct 121, due to its shape, can greatly reduce the obstruction to the airflow. Furthermore, according to the wall attachment effect, the sidewall of the exhaust duct 121 guides the airflow direction. Even if the rectifier duct 23 obstructs the airflow, the exhaust duct 121 sidewall can still achieve a seamless annular airflow from the ceiling panel. This solves the technical problem of dead airflow in related technologies.

[0039] In some embodiments, such as Figure 3 and Figure 4 As shown, the base frame 2 includes an outer frame 22 and an inner frame 21 that are arranged and connected inside and outside. The inner frame 21 is provided with a through second return air inlet 222. At least a portion of the outer side of the inner frame 21 and at least a portion of the inner side of the outer frame 22 enclose each other to form a rectifier air duct 23.

[0040] It should be noted that, as the name suggests, the inner frame 21 is connected to the inner side of the outer frame 22. "At least a portion of the outer side of the inner frame 21 and at least a portion of the inner side of the outer frame 22 enclose each other to form a rectifier duct 23" means that there is a connecting structure between the outer frame 22 and the inner frame 21, and the rectifier duct 23 does not run through the second return air inlet 222 circumferentially.

[0041] It is understandable that since the second return air vent 222 is located in the inner frame 21 and the rectifier air duct 23 is located between the outer frame 22 and the inner frame 21, it is equivalent to implicitly disclosing the air guide 1 on the inner frame 21, using the inner frame 21 to fix the air guide 1, so that an annular exhaust duct 121 can be set on the air guide 1.

[0042] In some embodiments, such as Figure 3 and Figure 4 As shown, the outer side of the inner frame 21 is provided with multiple connecting bridges 221 that connect to the inner side of the outer frame 22. The multiple connecting bridges 221 are spaced apart, and any two adjacent connecting bridges 221 together with the outer side of the inner frame 21 and the inner side of the outer frame 22 form a rectifier air duct 23.

[0043] It should be noted that the outer frame 22 and the inner frame 21 are fixed by the connecting bridge 221 to ensure the integrity of the ceiling machine panel structure.

[0044] It is understandable that, by utilizing the existing structure, namely the connecting bridge 221, the inner frame 21 and the outer frame 22, multiple rectifier air ducts 23 are set on the ceiling unit panel to minimize the dead air angles on the base frame 2.

[0045] For example, the outer side of the inner frame 21 can be set as an annular shape, and both the inner and outer sides of the outer frame 22 are set as square shapes. Each of the four apex corners of the inner side of the square outer frame 22 corresponds to one of the four connecting bridges 221. Thus, any side of the inner side of the square outer frame 22, the outer side of the inner frame 21, and the two connecting bridges 221 enclose a rectifier airflow duct 23. It can be imagined that such a rectifier airflow duct 23 is narrow in the middle and wide at both ends, thereby guiding more airflow to the area within the exhaust duct 121 that is blocked by the connecting bridges 221, promoting a more uniform airflow distribution within the exhaust duct 121, and weakening the obstructive effect of the connecting bridges 221.

[0046] In some embodiments, such as Figure 4 As shown, the rectifier duct 23 gradually increases in size along the direction close to the adjacent connecting bridge 221.

[0047] It is understandable that by increasing the size of the area of ​​the rectifier duct 23 near the connecting bridge 221, the air volume loss caused by the connecting bridge 221 can be compensated, so that the airflow distribution in the exhaust duct 121 is uniform and the exhaust duct 121 has a relatively consistent air volume at 360 degrees.

[0048] In some embodiments, such as Figure 4 and Figure 7 As shown, at least a portion of the rectifier duct 23 away from the exhaust duct 121 gradually increases in the direction away from the exhaust duct 121.

[0049] It should be noted that, along the air outlet direction of the rectifier duct 23, the middle of the side wall of the rectifier duct 23 can be used as a dividing line to divide the rectifier duct 23 into at least a portion away from the exhaust duct 121 and at least a portion close to the exhaust duct 121. For example, the portion of the rectifier duct 23 close to the connecting bridge 221 gradually increases in the direction away from the exhaust duct 121.

[0050] It is understandable that by having at least a portion of the rectifier duct 23 with the above-mentioned characteristics away from the exhaust duct 121, on the one hand, the air intake volume of the rectifier duct 23 can be increased, and on the other hand, the air pressure can be increased by narrowing the rectifier duct 23 along the air outlet direction, thereby accelerating the airflow guidance, ensuring that the air volume of the exhaust duct 121 gathers in all directions, and improving the circulation efficiency of the ceiling panel.

[0051] In some embodiments, such as Figure 5 and Figure 6As shown, the air guide 1 includes a return air section 11 and a guide section 12. The return air section 11 is provided with a first return air inlet 111 and is connected to the outside of the base frame 2. The guide section 12 is sleeved on the return air section 11 and blocks the rectifier air duct 23 along the air outlet direction of the rectifier air duct 23. The guide section 12 and the air outlet end of the rectifier air duct 23 are spaced apart to form an exhaust duct 121.

[0052] It should be noted that "the guide section 12 blocks the rectifier duct 23 along the air outlet direction of the rectifier duct 23" means that the guide section 12 can block the airflow blown out from the rectifier duct 23 from flowing to the air inlet side of the first return air inlet 111, so as to prevent the blown airflow from being fully cooled or heated in the room before being drawn back, and to prevent the ceiling unit panel from forming a circulation.

[0053] It is understandable that the air outlet side of the exhaust duct 121 should be located on the periphery of the return air section 11, so that the airflow is discharged horizontally, while the first return air inlet 111 draws air upward.

[0054] In some embodiments, such as Figure 5 and Figure 6 As shown, the base frame 2 is provided with a flow guide surface 24, which is located near the air outlet of the rectifier air duct 23 and is inclined in a direction away from the flow guide part 12.

[0055] It should be noted that "the guide surface 24 is inclined in the direction away from the guide section 12" means that the guide surface 24 extends away from the guide section 12, i.e., upwards, relative to the horizontal plane. It can be imagined that the exhaust duct 121 gradually increases in size along the direction perpendicular to the return air direction of the first return air inlet 111. It is understandable that, based on the wall adhesion effect, when airflow exits from the rectifier duct 23 and flows towards the exhaust duct 121, the guide surface 24 at the edge of the exhaust duct 121 causes the airflow to tend to flow along this guide surface 24, further guiding the airflow away from the first return air inlet 111.

[0056] For example, since the exhaust duct 121 is annular, the drainage surface 24 can be set as an annular plane or an annular arc surface, with the arc surface protruding in the direction close to the guide portion 12. It is not difficult to imagine that such a drainage surface 24 has an upward tilting tendency.

[0057] Furthermore, the surface of the guide section 12 facing the guide surface 24 can be configured as a guide surface 122. The guide surface 122 extends upward and can be configured as an annular inclined surface or an annular arc surface. Along the air outlet direction of the rectifier duct 23, the guide surface 122 is larger than the air outlet of the rectifier duct 23 to better block the airflow.

[0058] In some embodiments, such as Figure 5 and Figure 6As shown, along the return air direction of the first return air inlet 111, there is a distance between the exhaust duct 121 and the air inlet of the first return air inlet 111.

[0059] Understandably, ceiling fans are typically installed horizontally on the ceiling. Therefore, the return air direction of the first return air vent 111 points towards the ceiling. Taking the air inlet of the first return air vent 111 as a reference plane, the exhaust duct 121 is located above the air inlet of the first return air vent 111. By increasing the distance between the exhaust duct 121 and the first return air vent 111 in the direction of gravity, the possibility of backflow after exhausting air from the exhaust duct 121 is further reduced.

[0060] In some embodiments, such as Figure 7 As shown, at least a portion of the rectifier duct 23 near the exhaust duct 121 gradually increases in size along the direction near the exhaust duct 121.

[0061] It should be noted that, along the air outlet direction of the rectifier duct 23, the middle part of the side wall of the rectifier duct 23 can be used as the dividing line to divide the rectifier duct 23 into at least a part away from the exhaust duct 121 and at least a part close to the exhaust duct 121.

[0062] It is understood that by increasing the size of at least a portion of the rectifier duct 23 near the exhaust duct 121, the airflow distribution within the exhaust duct 121 is balanced, and the airflow to the area within the exhaust duct 121 blocked by the connecting bridge 221 is increased. Exemplarily, the portion of the rectifier duct 23 near the connecting bridge 221 gradually increases in size along the direction near the exhaust duct 121.

[0063] In some embodiments, such as Figure 1 As shown, the air guide 1 also includes a grille 13, which is disposed at the air inlet end of the first return air inlet 111. The grille 13 can prevent foreign objects from being sucked in.

[0064] This application also provides a riser, which includes the riser panel described above. The specific structure of the riser panel is as described in the above embodiments. Since this riser 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.

[0065] The ceiling fan is used for installation on the ceiling and also includes a heat exchanger, which is located on the side of the base frame 2 away from the guide member 1.

Parts not described in detail in a particular embodiment can be referred to in the relevant descriptions of other embodiments. In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features.
