1. Field of the Disclosure
The present Invention relates to a ventilation device, and particularly, to a ventilation device with a LED lighting device.
2. Description of the Related Art
In the above mentioned ventilation device 10 of the prior art, the lighting device 15 of the ventilation device 10 is provided with a fluorescent lamp 16 where a ballast is needed. Thus, the entire volume of the ventilation device 10 becomes large. Furthermore, the cost of manufacturing and using the ventilation device 10 increases.
In order to achieve miniaturization of the lighting device 15, it is desirable to arrange the ballast adjacent to the fluorescent lamp 16. Thus, the ballast is fixed in the prior art inner side the lampshade 18 of the ventilation device 10.
When the ventilation device 10 operates, indoor air is sucked in through the lampshade 18 and passed around the lighting device 10. However, water droplets or vapor may enter inside of the lighting device 15 when the ventilation device 10 is used to discharge the air having high humidity, such as, in a bathroom. As such, it causes potential risk during operation of the ventilation device.
The present invention has been made to overcome or alleviate at least one of the above-mentioned problems and drawbacks existing in the prior arts.
Accordingly, it is an object of the present Invention to provide a ventilation device which achieves an increased safety. The ventilation device including a lighting device enables rapidly discharge water even if water droplets or vapor would enter into a circuitry box for driving the lighting device, thereby enhancing durability.
In order to achieve the above mentioned objective, according to an aspect of the invention, there is provided a ventilation device comprising a frame provided with an opening, a fan disposed in the frame, a panel covering the opening of the frame and allowing air to pass through and a lighting device disposed in the panel. The lighting device comprises a lampshade, in which a lighting part is disposed, and a circuitry box of a controller for controlling the lighting device. The lampshade and the circuitry box are formed in a separate structure such that the lampshade and the circuitry box may are made of metal and resin, respectively, wherein a gap is formed in a connection between the circuitry box and the panel, such that a water discharge structure communicated with the outside of the circuitry box is formed.
The lampshade and the circuitry box are both provided with a lead wire hole through which a lead wire passes between the lighting part and the controller.
The lead wire hole of the circuitry box is configured to be an oblique formation.
A water discharge port is provided in bottom of the wall of the circuitry box at which the lead wire hole is provided.
The panel is provided with a stop plate around which a bracket is provided, the bracket is provided with a notch communicated with inside of the panel in a side thereof, the circuitry box is configured to be a box body disposed in the bracket and for shielding the stop plate, a gap is formed between the side of the opening of the box body adjacent to the notch and the stop plate and configured to communicate with the notch.
A lid is disposed for the circuitry box at the lower side thereof, which is provided with a notch corresponding to the water discharge port.
A groove is provided at a side of the stop plate with a width greater than the thickness of the wall of the box body of the circuitry box and a gap is formed between the groove and a side of the box body.
The panel is provided with grids through which air passes. With respect to the grids, the face forming a face of the panel is configured to be nearer to the outer surface and the stop plate is configured to be nearer to the inner face, such that the thickness of the grids is greater than a sum of those of the panel and the stop plate.
The stop plate is placed at a position at a higher level than that of the panel, such that the groove of the stop plate is formed by placing a side of the stop plate at a position at a same level as inner face of the panel.
The stop plate is provided with a chamfer thereby a structure directing to the groove is formed.
A side of the box body of the circuitry box is formed to be shorter than the other side thereof such that a gap is formed between the shorter side and the stop plate.
At least one of the following advantages of the present invention is achieved. A gap communicated with outside of the circuitry box is provided in a connection between the circuitry box and the panel, which allows water to be discharged through the gap from inside of the panel, even water would enter into the inside of the circuitry box. Therefore, an improved safety of the ventilation device is achieved.
In
When there is water flowing down along the gap between the circuitry box 220 and the lampshade 210, water will flow directly to bottom of the circuitry box 220 and the lampshade 210 along the gap therebetween, rather than enter into the circuitry box 220, and then be discharged through the water discharge port 2300 provided in the bottom of the wall of the circuitry box 220.
Again, as shown in
A groove 1414 is provided with a width bigger than the thickness of the wall of the box body of the circuitry box 220 close to a side of the stop plate 141 and a gap 300 is formed between the stop plate 141 and a side of the box body. In a specific example, the thickness of the box body is 2 mm while the width of the groove is 2.6 mm.
As illustrated in
That is, the stop plate 141 is placed at a position at a higher level than the inside face 146 of the panel 14. The groove 1414 of the stop plate 141 is formed by placing a side of the stop plate 141 at a position at the same level as the inside face 146 of the panel 14.
Furthermore, a protrusion piece 222 is provided on the side 2201 of the circuitry box 220 facing the groove 1414 and it is fixed to a protrusion part 223 on the panel by means of a screw, it allows the position relationship between the groove 1414 and the side 2201 of the circuitry box 220 to be secured, thereby forming a water discharge. When the box body of the circuitry box 220 is received in the bracket 142, the side 2201 of the box body of the circuitry box 220 is not in contact with the stop plate 141, thereby the gap 300 is formed. Further, water droplets attached on the stop plate 141 may be discharged from inside of the stop plate 141 through the gap 300. The stop plate 141 is provided with a chamfer 145 on the end face, which leads to a structure directing to an inside of the groove 1414 and causes water droplets on the stop plate 141 to be guided to the groove 1414.
