The side walls 217 are four planar shells, which are not parallel to each other in the top plate 218, and the top plate 218 and the side walls. The 217 is connected, and the sidewall 217 defines a first opening 219 with respect to the top plate 218. The first opening 219 abuts the mounting opening C2. The top plate 218 and the side wall 217 can be integrally formed or assembled, and can be made of materials such as dustproof, waterproof or fireproof plastic, metal or alloy. In addition, the outer casing 21 further has at least one extension portion 214 which can be disposed on the top plate 218 or the side wall 217. The extension portion 214 is formed by pressing the outer casing 21, and other components can be coupled to the outer casing 21 by the extension portion 214.

In detail, the present embodiment has four-sided side walls 217, and the four-sided side walls 217 and the top plate 218 are perpendicular to each other. The outer casing 21 may also have a top plate and side walls of different configurations, such as a multi-faceted side wall, an arcuate side wall, a cylindrical case, etc., and the invention is not limited thereto. In addition, the first opening 219 is an opening formed by the outer casing 21 removing the rectangular bottom plate, that is, the outer casing 21 of the embodiment is a rectangular box or a pentahedron having no bottom plate, and thus from FIG. 1B As seen in the exploded view and the cross-sectional view shown in Fig. 1D, the outer casing 21 is substantially a casing which exhibits a bottomless U-shaped shape.

In addition to having the first opening 219, the outer casing 21 may have an air outlet opening 212 as an outlet for the ventilating fan 2 to exclude gas or an opening for connecting the external air outlet passage. The first opening 219 and the outlet opening 212 are respectively located on different planes of the outer casing 21. The outer casing 21 of the ventilating fan 2 can be mounted on the mounting opening C2 of the ceiling C, and is aligned with the mounting opening C2 of the ceiling C through the first opening 219 so that the mounting opening C1 and the first opening 219 can communicate with each other. At the same time, the first opening 219 of the outer casing 21 and the mounting opening C2 of the ceiling C may have substantially the same inner diameter size.

The fan module 22 is housed in the outer casing 21. In this embodiment, the fan module 22 includes a fan casing 221, an impeller 222, and a motor 223, and the fan module 22 is disposed corresponding to the mounting opening C2, that is, a sectional view from FIG. 1D. It should be noted that the fan module 22 is located just above the mounting opening C2 of the ceiling C, but is not limited thereto. The impeller 222 is received in the fan housing 221, and the motor 223 is coupled to the impeller 222 and can drive the impeller 222 to rotate. Preferably, the motor 223 can optionally use a DC motor, which reduces power consumption compared to a general motor. The fan casing 221 has an air inlet 2211 and an air outlet 2212. The air outlet 2212 communicates with the air outlet 212. In addition, both the impeller 222 and the motor 223 can be fixed in the fan housing 221 by locking or snapping. In addition, the outer diameters of the motor 223 and the impeller 222 may be smaller than the inner diameter of the first opening 219, respectively. In other words, the user can remove the motor 223 and the impeller 222 from the fan housing 221 through the first opening 219 or assemble to the fan housing 221 to facilitate maintenance or maintenance of the fan module 22.

1D, the fan module 22 has a first projection surface A1 on the top plate 218, the mounting opening C1 has a second projection surface A2 on the top plate 218, and the area of the first projection surface A1 is smaller than that of the second projection surface A2. The area, and the second projection surface A2 at least partially overlaps the first projection surface A1. Therefore, the fan unit can be taken out from the first opening 219 of the outer casing 21 and the mounting opening C2 of the ceiling C to facilitate product maintenance.

The luminaire module 23 is disposed outside the mounting opening C2 of the ceiling C and on a side away from the outer casing 21. The area of the mounting opening C2 is smaller than the area of the outer peripheral edge of the lamp module 23, and the external airflow enters the outer casing 21 in a laterally inflow manner. Specifically, the external airflow flows between the ceiling C and the luminaire module 23, and enters the casing 21 through the mounting opening C2 of the ceiling C and the first opening 219 of the casing 21. In this embodiment, the lamp module 23 is a flat-plate side-light type lamp module. In detail, the lamp module 23 includes a light source B, a base 231, at least one optical component 232, and a lamp cover 233. The optical component 232 is disposed on the base 231 together with the light source B, and the lamp cover 233 is disposed on a side of the optical component 232 that is away from the base 231. The light source B of this embodiment is at least one light emitting diode (LED) and is located on one side of the optical component 232. The LED and its driving components can be integrated on a substrate, that is, "driver on board (DOB)", but not limited thereto.

In addition, the optical component 232 of the embodiment is exemplified by a light diffusing plate that can receive the light emitted by the light source of the lamp module 23. Referring to the illustration, the light emitted by the light source B of the sidelight type lamp module 23 can be incident on the optical component 232. In this embodiment, the light can be incident on the light diffusing plate, and the light diffusing plate receives the incoming light. Thereafter, the light will be emitted in a direction away from the ceiling and the outer casing 21 after penetrating the lampshade 233. That is to say, the direction of the light emitted by the light source of the embodiment is not equal to the light exiting direction of the lamp module 23, and the direction of the light emitted by the light source of the lamp module 23 is actually perpendicular to the light exiting direction of the lamp module 23.

In this embodiment, the light source B is a light-emitting diode (LED), and the direction of the light emitted by the light source B is not equal to the light-emitting direction of the lamp module 23. The illuminating module 23 adopts a flat-plate side-light design, and then the diffused light is used to diverge the light emitted by the light source to form a planar light source, so that the light source B of the luminaire module 23 emits light perpendicular to the luminaire module 23 . The direction of light. Compared with the light source of the conventional direct type LED, the lamp module 23 of the embodiment can have a better uniform softness and a non-glare illumination feeling. In addition, the luminaire module 23 may further include a heat dissipating component, such as a heat dissipating fin, which may be optionally disposed on the pedestal 231 or attached to the substrate for heat dissipation. Moreover, in other implementations, the luminaire module 23 can be further matched with a dimmable switch, and can perform various dimming for the light source according to different usage scenarios, such as changing the illuminating color, changing the illuminating brightness, and changing The illuminating frequency or the like further causes the ventilating fan of the present invention to have different context lighting modes. Alternatively, in other embodiments, the luminaire module 23 can also use different optical components according to different lighting requirements, for example, using a lens or a lens group as an optical component. The lens can be disposed opposite to the base and coupled to the lamp cover to achieve different illumination effects by utilizing the ability of the lens to gather and diverge light.

The technical content of the connecting member of the ventilating fan of this embodiment will be described in further detail below.

Referring to FIG. 1D, in the embodiment, the ventilating fan 2 further includes a connecting member E disposed on the luminaire module 23, wherein the connecting member E is an elastic member. The fan module 22 has a fan housing 221 that connects the lamp module 23 to the fan housing 221 or the housing 21 through the connector E. It is further explained that the lamp module 23 can be disposed on the fan housing 221 or the at least one extension portion 214 of the outer casing 21 by the connecting member E, or can be selectively changed to be worn in other embodiments. The casing 21 has a slot (not shown) and is fixedly disposed outside the mounting opening C2 of the ceiling C. In this embodiment, the connecting member E is disposed on the extending portion 214 of the fan housing 221. In another embodiment, the fan housing 221 or the housing 21 can also have a plurality of extending portions 214. Not only does it have a single slot, it further enhances the stability of the lamp module 23 when it is placed on the ventilating fan 2. Specifically, the connecting member E is substantially a V-shaped metal member, wherein both ends of the V-shaped structure respectively have a barb structure E1, and the bottom of the V-shaped structure has a ring at the intersection of the barb structures E1 at both ends. The body E2 and the ring body E2 may be partially connected to the lamp module 23, for example, to the outer casing of the lamp module 23.

Here, when the lamp module 23 is mounted outside the mounting opening C2 of the ceiling C, the barb structure E1 is directly pressed first to keep the end barb structure close to enable the connector E to pass through the fan casing. The extension portion 214 of the 221, and then the end barb structure of the two barb structures E1 are correspondingly fixed to the extension portion 214. When the lamp module 23 is disassembled, the user can also close the barb structure of the end bar by pressing the two barb structures E1, and the barb structure E1 is removed by the extension portion 214, and the lamp module can be removed after being pulled down. The group 23 is released from the fixed state and does not need to be disassembled by the tool. Therefore, the lamp module 23 can be easily disassembled and assembled to facilitate the maintenance or maintenance of the ventilating fan 2. At the same time, due to the design of the connector E, during the process of disassembling the lamp module 23, the lamp module 23 will be suspended because the barb structure is still stuck in the extension portion 214, and will not be directly removed. The lamp module 23 can be smoothly removed by pressing the two barb structures E1 of the connector E.

After the lamp module 23 is fixedly disposed on the mounting opening C2 of the ceiling C through the connecting member E, the lamp module 23 can abut against the ceiling C. In this embodiment, the ventilating fan further includes a bracket 25 disposed between the ceiling C and the luminaire module 23, and the bracket 25 abuts the ceiling C. There is a gap I between the lamp module 23 and the bracket 25, and the gap I is actually the air inlet portion of the ventilating fan 2. Specifically, the gap I is interposed between the lower surface of the bracket 25 and the upper surface of the outer casing of the lamp module 23, and the gap I is a side inlet air inlet.

In the present embodiment, the mounting gap between the lamp module 23 and the bracket 25 and the ceiling C can be absorbed because of the action of the connecting member E. The lamp module 23 is connected to the bracket 25 through the abutting portion 2312. Further, the length of the abutting portion 2312 is equal to the width of the gap I, and the width of the gap I as the inlet air may actually be between 5 mm and 20 mm.

The overall operation of the ventilating fan 2 will be described in detail below.

It should be noted that the airflow flows from the gap I between the ceiling C and the lamp module 23, and passes through the mounting opening C2 of the ceiling C and the first opening 219 of the outer casing 21 before entering the outer casing 21. Referring to FIG. 1D, the air inlet 2211 of the fan casing 221 is located on the fan casing 221 near the first opening 219, that is, the air inlet 2211 and the first opening 219 are oriented in the same direction. In this way, through the air inlet hole 2211 of the fan module 22, the gas sucked by the gap I can be directly guided to improve the intake efficiency. Then, after the gas flows through the air inlet hole 2211 of the fan casing 221, it is discharged through the air outlet hole 2212 and the air outlet opening 212 of the outer casing 21. In addition, the fan module 22 of the embodiment may further have a baffle 224 disposed in the air outlet opening 212 to prevent backflow of gas when the fan module 22 is not in operation. Moreover, the lamp module 23 can also be independently provided with a switch, which can be turned on or off according to the needs of the user, and does not need to be completely activated together with the fan module 22, that is, the ventilation function is independent of the illumination function.

Thereby, the ventilating fan having the luminaire of the embodiment is mounted on the ceiling, the ceiling has a mounting opening, and the ceiling has a mounting opening. The ventilating fan includes a casing, a fan module, and a luminaire module. The outer casing has a top plate and a side wall, and the top plate is connected to the side wall. The side wall and the top plate enclose a first opening, and the first opening abuts the mounting opening. The fan module is housed in the housing. The luminaire module is disposed outside the mounting opening of the ceiling and located on a side away from the first opening. The ventilation fan is designed by the side suction type, and the lamp module can further block the noise generated when the fan module is running. In addition, the user cannot directly see the internal structure of the ventilating fan, making the overall appearance of the ventilating fan more elegant. And through the integration of the luminaire module to the ventilating fan, it can be installed in various environments, and can reduce the use space of the ceiling to improve the utilization efficiency of the overall space.

The embodiment of the ventilating fan-related bracket 25 will be described below.

The difference between the ventilating fans 2 and 2a of FIGS. 1B and 1C is that the screen 252 provided on the bracket 25 is optional. As shown in FIG. 1B, the ventilating fan 2 can be a primary filter. The filter 252 can be installed or taken out according to the user's requirements. The ventilating fan 2a shown in FIG. 1C is in the form of no filter 252.

As shown in FIG. 2A to FIG. 2C, the ventilating fan 2b can also remove the bracket 25 as needed, and directly illuminate the luminaire module 23 through the abutting portion 2312 against the ceiling C, between the luminaire module 23 and the ceiling C. There is a gap I, and the gap I is actually the inlet of the ventilating fan 2. In addition, the gap I between the lamp module 23 and the ceiling C can also be adjusted by the abutting portion 2312 to meet the flow field design required for the ventilating fan 2b. Wherein, the distance of the gap I is between 5 mm and 20 mm, and the length of the abutting portion 2312 is equal to the width of the gap I.

For other technical features of the ventilating fan 2b, reference may be made to the related description of the ventilating fan 2, and details are not described herein again.
