The present invention relates to a wall-mounted fan, and more particularly, to a waterproof structure of a wall-mounted fan housing.
After the ceiling fan is installed, the user won't regularly check the deterioration of the sealing rings of the ceiling fan. When the first sealing ring 2 and the second sealing ring 6 are used for a long time and are not periodically replaced, the first sealing ring 2 and the second sealing ring 6 may be deteriorated and damaged. As a result, the waterproof function of the ceiling fan is ineffective, and rainwater accumulates in the motor housing. If the first sealing ring 2 and the second sealing ring 6 are damaged, a gap will be generated between the adapter 5 and the motor housing 4. When the ceiling fan is running, the adapter 5 and the motor housing 4 may shake, collide with or disengage from each other to cause a danger. Accordingly, the inventor of the present invention has devoted himself based on his many years of practical experiences to solve these problems.
The primary object of the present invention is to provide a waterproof structure of a wall-mounted fan housing, which can be used for outdoor waterproofing without the use of a sealing ring. The housing has waterproof and drainage functions to prevent water from accumulating in the housing and can be assembled more easily.
In order to achieve the aforesaid object, the waterproof structure of the wall-mounted fan housing of the present invention comprises a housing, a motor, and a first drain hole. The housing has an accommodation space therein. The housing has a main housing and a secondary housing. One side of the main housing has a main opening. The main housing has a connecting portion around a periphery of the main opening. One side of the secondary housing has a first secondary opening. The connecting portion of the main housing is fitted on an outer wall of the first secondary opening of the secondary housing. Respective insides of the main housing and the secondary housing jointly form the accommodation space. The housing and the accommodation space of the housing are inclined downward from the main housing toward the secondary housing. Another side of the secondary housing has a second secondary opening. The motor is disposed in the accommodation space of the housing. A rotating shaft of the motor extends toward the second secondary opening of the secondary housing. The first drain hole is disposed at a bottom of the secondary housing close to the second secondary opening of the secondary housing. The first drain hole is lower than the motor.
When it is raining, because the connecting portion of the main housing is fitted on the outer wall of the secondary housing and the housing and the accommodation space of the housing are inclined downward from the main housing toward the secondary housing, rainwater won't enter the accommodation space of the housing from the gap between the main housing and the secondary housing. If rainwater enters the accommodation space of the housing from the second secondary opening of the secondary housing, the rainwater can be discharged from the first drain hole. Because the first drain hole is lower than the motor, the rainwater does not accumulate to the motor.
Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings.
The housing 10 has an accommodation space 11 therein. The housing 10 has a main housing 12 and a secondary housing 13. One side of the main housing 12 has a main opening 121. The main housing 12 has a connecting portion 122 around the periphery of the main opening 121. One side of the secondary housing 13 has a first secondary opening 130. The connecting portion 122 of the main housing 12 is fitted on the outer wall of the first secondary opening 130 of the secondary housing 13. The connecting portion 122 of the main housing 12 is provided with a screw hole 123. The secondary housing 13 is provided with a locking hole 131 corresponding to the screw hole 123 for locking. The respective insides of the main housing 12 and the secondary housing 13 jointly form the accommodation space 11. The housing 10 and the accommodation space 11 of the housing 10 are inclined downward from the main housing 12 toward the secondary housing 13. Another side of the secondary housing 13 has a second secondary opening 132. The outer wall of the secondary housing 13, adjacent to the second secondary opening 132, is provided with an extension portion 133 around the second secondary opening 132. The extension portion 133 is tapered outwardly to prevent infiltration of rainwater. The housing 10 is made of a sealing waterproof material. In an embodiment of the present invention, the housing 10 has a circular curve shape.
The motor 20 is disposed in the accommodation space 11 of the housing 10. The motor 20 has a rotating shaft 21. The rotating shaft 21 extends toward the second secondary opening 132 of the secondary housing 13. The motor 20 is spaced a distance from the inner wall of the housing 10.
The support rod 30 is disposed at the bottom of the housing 10. The support rod 30 penetrates through the main housing 12 and the secondary housing 13. The support rod 30 is located under the motor 20.
The first drain hole 40 is disposed at the bottom of the secondary housing 13 close to the second secondary opening 132 of the secondary housing 13. The position of the first drain hole 40 is lower than the motor 20.
Referring to
The recess 50 is disposed in the accommodation space 11 of the housing 10. In this embodiment, the recess 50 is disposed in the accommodation space 11 of the housing 10. The recess 50 is located between the support rod 30 and the first drain hole 40. The recess 50 is non-parallel to the axial direction of the housing 10. Wherein, the recess 50 is provided with a second drain hole 51. The position of the second drain hole 51 is lower than the second secondary opening 132 of the secondary housing 13. Wherein, the recess 50 is an elongated recess. The recess 50 is disposed at the bottom of the secondary housing 13.
The raised portion 60 is disposed at the bottom of the accommodation space 11 of the housing 10. Wherein, the secondary housing 13 is provided with the raised portion 60. The raised portion 60 is located between the first drain hole 40 and the second drain hole 51. A guide slope 61 is provided between the raised portion 60 and the second drain hole 51. The position of the raised portion 60 is higher than the first drain hole 40 and the second drain hole 51.
The inner wall of the housing 10 is recessed outwardly to form the recess 50 so that the flange 70 is formed on the outer wall of the recess 50 of the housing 10. The flange 70 is disposed on the secondary housing 13 of the housing 10. The connecting portion 122 of the main housing 12 leans against the flange 70.
In the third embodiment of the present invention, when the housing 10 is assembled, the connecting portion 122 of the main housing 12 abuts against the flange 70 so that the screw hole 123 of the main housing 12 is aligned with the locking holes 131 of the secondary housing 13 more easily. When rainwater enters the accommodation space 11, since the raised portion 60 is disposed between the first drain hole 40 and the second drain hole 51, the rainwater is guided and diverted to the first drain hole 40 and the second drain hole 51. Besides, the recess 50 is located between the support rod 30 and the first drain hole 40, and the recess 50 is non-parallel to the axial direction of the housing 10, such that the rainwater is more likely to be collected in the recess 50 and is discharged from the second drain hole 51 to the outside of the housing 10.
Although particular embodiments of the present invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the present invention. Accordingly, the present invention is not to be limited except as by the appended claims.
