Description

Technical Field

[0001] The utility model relates to the technical field of fans, and particularly relates to a ceiling fan top cover and a ceiling fan. Background Art

[0002] When a ceiling fan motor operates, it generates heat. If the ceiling fan runs at a high speed for a long time, it may burn out. When the ceiling fan is running, if the motor can be cooled, the service life of the motor can be effectively extended. In order to cool the motor of the ceiling fan, in the prior art, heat dissipation holes are opened at the top of the motor housing. Although these heat dissipation holes can promote the heat dissipation in the motor housing to a certain extent, since these heat dissipation holes are flat holes, the heat dissipation effect is still limited. Content of the Utility Model

[0003] In view of the deficiencies of the above prior art, the purpose of the utility model is to provide a ceiling fan top cover and a ceiling fan, aiming to improve the heat dissipation effect of the ceiling fan motor.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] The utility model provides a ceiling fan top cover in the first aspect, including a cover body. Among them, a plurality of air intake channels and a plurality of air outlet channels are arranged on the cover body; the air intake channels and the air outlet channels communicate the upper and lower spaces of the cover body; the air inlet of the air intake channel protrudes from the top surface of the cover body and faces the rotation direction of the ceiling fan.

[0006] For the above ceiling fan top cover, a through hole is arranged in the middle of the cover body, and the through hole is used for a suspension rod to pass through; a plurality of the air intake channels and the air outlet channels are circumferentially arranged around the through hole, and a plurality of the air intake channels and the air outlet channels are arranged alternately.

[0007] For the above ceiling fan top cover, the upper wall of the air intake channel extends obliquely upward in the rotation direction of the ceiling fan, and is used for introducing the air above the cover body into the air intake channel.

[0008] For the above ceiling fan top cover, the lower wall of the air intake channel extends obliquely downward in the direction opposite to the rotation direction of the ceiling fan.

[0009] For the above ceiling fan top cover, the lower wall of the air outlet channel extends obliquely downward in the rotation direction of the ceiling fan, and is used for introducing the air below the cover body into the air outlet channel.

[0010] For the above ceiling fan top cover, the upper wall of the air outlet channel extends obliquely upward in the direction opposite to the rotation direction of the ceiling fan.

[0011] For the above ceiling fan top cover, a protection net is arranged at the air inlet of the air intake channel.

[0012] For the ceiling fan top cover described above, the distance from the air intake channel to the through hole is less than or greater than the distance from the air outlet channel to the through hole.

[0013] In a second aspect of the present utility model, there is provided a ceiling fan, including a motor, a motor housing, and a plurality of fan blades. Among them, the motor housing includes a bottom cover and the ceiling fan top cover described above; the bottom cover and the ceiling fan top cover are fixedly connected; the plurality of fan blades are respectively fixedly connected to the ceiling fan top cover; the motor is connected with a suspension rod; the suspension rod passes through the through hole and is used to be fixed on the ceiling.

[0022] The present utility model provides a ceiling fan top cover and a ceiling fan. To make the purpose, technical solution, and effects of the present utility model clearer and more definite, the following further describes the present utility model in detail with reference to the accompanying drawings and by way of examples. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0023] In the description of the present utility model, it should be understood that the terms "upper", "lower", "left", "right", etc. indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, as well as a specific orientation structure and operation. Therefore, it should not be construed as a limitation to the present utility model. In the description of the present utility model, unless otherwise specified, the meaning of "a plurality" is more than two.

[0024] Please refer to Figure 1 , a first aspect of the present utility model provides a ceiling fan top cover, including a cover body 1. Among them, a plurality of air intake channels 12 and a plurality of air outlet channels 13 are provided on the cover body 1; the air intake channels 12 and the air outlet channels 13 communicate the upper and lower spaces of the cover body 1; the air intake openings of the air intake channels 12 protrude from the top surface of the cover body 1 and face the rotation direction of the ceiling fan. The ceiling fan top cover is used as the top cover of the motor housing. When the ceiling fan rotates, the air intake openings of the air intake channels 12 protruding from the top surface of the cover body 1 continuously introduce air into the motor housing, and then the air carries the heat in the motor housing and discharges it from the air outlet channels 13. Compared with the flat hole design of the prior art, the ceiling fan top cover of the present utility model can effectively improve the heat dissipation efficiency of the motor, reduce the thermal aging of the motor, and extend the service life of the ceiling fan.

[0025] Please refer to Figure 1 , in an embodiment, a through hole 11 is provided in the middle of the cover body 1, and the through hole 11 is used for the suspension rod 2 to pass through; a plurality of the air intake channels 12 and the air outlet channels 13 are circumferentially arranged with the through hole 11 as the center, and the plurality of the air intake channels 12 and the air outlet channels 13 are arranged alternately. In this embodiment, the alternately arranged air intake channels 12 and air outlet channels 13 can allow the low-temperature air outside to enter the motor housing from the air intake channels 12, and the high-temperature air formed after heat exchange can be immediately discharged through the air outlet channels 13, accelerating the air exchange speed, thereby improving the heat dissipation effect.

[0026] Preferably, three air intake channels 12 and three air outlet channels 13 are provided on the cover body 1. By reasonably setting the number of the air intake channels 12 and the air outlet channels 13, it is possible to avoid the air intake openings of the air intake channels 12 and the air outlet openings of the air outlet channels 13 being too close while achieving the best heat dissipation effect.

[0027] Please refer to Figure 2 , in an embodiment, the distance from the air intake channel 12 to the through hole 11 is less than or greater than the distance from the air outlet channel 13 to the through hole 11. In this embodiment, the air intake openings of the air intake channels 12 and the air outlet openings of the air outlet channels 13 are staggered and not on the same rotation route, so that the air intake channels 12 behind can reduce the intake of the hot air discharged from the air outlet channels 13 in front.

[0028] Please refer to Figure 1 and Figure 3 In one embodiment, the upper wall of the air intake passage 12 extends obliquely upward in the rotation direction of the ceiling fan, and is used to introduce the air above the cover 1 into the air intake passage 12. Specifically, the upper wall of the air intake passage 12 protrudes from the top surface of the cover 1, so that the air intake passage 12 has an air intake opening that slopes downward. When the ceiling fan rotates, the inclined upper wall of the air intake passage 12 can reduce air resistance and allow air to enter the motor housing more smoothly.

[0029] Please refer to Figure 1 and Figure 3 In one embodiment, the lower wall of the air intake passage 12 extends obliquely downward in the direction opposite to the rotation direction of the ceiling fan. In this embodiment, the lower wall of the air intake passage 12 extending obliquely downward can direct fresh air to the motor and prevent hot air from being discharged from the air intake passage 12.

[0030] Please refer to Figure 1 and Figure 3 In one embodiment, the lower wall of the air outlet passage 13 extends obliquely downward in the rotation direction of the ceiling fan, and is used to introduce the air below the cover 1 into the air outlet passage 13. In this embodiment, when the hot air in the motor housing encounters the inclined lower wall of the air outlet passage 13, it can move upward along the lower wall of the air outlet passage 13. Compared with the flat hole design, the inclined lower wall of the air outlet passage 13 can better discharge the hot air from the motor housing.

[0031] Please refer to Figure 1 and Figure 3 In one embodiment, the upper wall of the air outlet passage 13 extends obliquely upward in the direction opposite to the rotation direction of the ceiling fan. The upper wall of the air outlet passage 13 can prevent low-temperature air from entering the motor housing through the air outlet passage 13, and at the same time allow the hot air in the motor housing to flow smoothly through the air outlet passage 13. In addition, the inclined upper wall of the air outlet passage 13 can reduce wind resistance.

[0032] Please refer to Figure 4 In one embodiment, a protective net 14 is provided at the air intake opening of the air intake passage 12. The protective net 14 is used to prevent large foreign objects from entering the motor housing through the air intake passage 12.

[0033] Please refer to Figure 5, the second aspect of the present utility model provides a ceiling fan, which includes a motor, a motor housing, and multiple fan blades 4. Among them, the motor housing includes a bottom cover 3 and the ceiling fan top cover as described above; the bottom cover 3 and the ceiling fan top cover are fixedly connected; multiple fan blades 4 are respectively fixedly connected to the ceiling fan top cover; the motor is connected with a suspension rod 2; the suspension rod 2 passes through the through hole 11 and is used to be fixed on the ceiling. When the motor operates, it will drive the motor housing and the fan blades 4 to rotate, thereby generating wind. When the motor housing rotates, the ceiling fan top cover of the present utility model can allow more air to enter the motor housing, thereby achieving a better heat dissipation effect.

[0034] In summary, by optimizing the structure of the ceiling fan top cover, the present utility model provides multiple air intake channels 12 and multiple air outlet channels 13 on the cover body 1, and the air inlet of the air intake channel 12 protrudes from the top surface of the cover body 1 and faces the rotation direction of the ceiling fan. During the rotation of the ceiling fan, more air continuously passes through the air inlet and enters the lower part of the ceiling fan top cover along the air intake channel 12, so that the heat in the motor housing dissipates faster.

[0035] It can be understood that for those of ordinary skill in the art, equivalent substitutions or changes can be made according to the technical solutions and the inventive concept of the present utility model, and all such changes or substitutions should fall within the protection scope of the appended claims of the present utility model.
