The joint 13 includes a joint plate 131 connected to the frame body 11 and a pipe connecting portion connected to the pipe. Before using this ventilating fan, the pipe is sleeved on the pipe connecting portion of the joint 13, and the air blown out from the air outlet 15 can be guided to be blown outside through the joint 13 and the pipe.

As shown in Figure 1, when the above-mentioned ventilator fan is installed on the integrated ceiling, in order to maintain the overall consistency of the indoor integrated ceiling and improve the overall aesthetics of the living room environment, the frame body 11 frame body opening 110 (including the frame body The overall size of the bottom surface of the flange 19) (the size in this application refers to the size of the component in the direction parallel to the gusset plate of the integrated ceiling or the wooden board of the ordinary ceiling when the fan of the ventilation device is installed, the same below) is less than The size of one pinch plate 50, and make the size of the mask 12 of the ventilator fan consistent with the size of the pinch plate 50, so that the face mask 12 of the ventilator can replace a pinch plate 50 to cover the frame body opening 110 and the frame at the bottom of the frame. The body flange 19 is installed, and its height can be consistent with the surrounding gusset plate 50 instead of protruding toward the interior side of the room and being lower than the surrounding gusset plate 50 . However, the size of the gusset 50 of the integrated ceiling is relatively small. For example, the commonly used gusset size is 300mm*300mm. The overall size of the flange 19 of the upper frame needs to be less than 300mm*300mm. In order to ensure sufficient air passage volume and component installation space inside the frame, the size of the frame opening 110 cannot be set too small. Therefore, it is necessary to reduce the size of the frame flange 19, that is, the frame flange 19 is separated from the frame opening. The length of the outer circumference extending outward.

As shown in Figure 2, when the above-mentioned ventilation device is installed on a common suspended ceiling, a ceiling opening for inserting and installing the frame body 11 needs to be cut on the ceiling in advance, and since the frame body 11 is tightly attached to the frame body 19 through the frame body flange 19 Positioned below the ceiling, the size of the ceiling opening must be larger than the size of the frame opening and smaller than the total size of the frame opening plus the frame flange 19 . In addition, before the frame body 11 is passed through the ceiling opening, the joint 13 connected to the air outlet 15 needs to be passed through the ceiling opening and the joint 13 is fixed on the ceiling; and after the power cord is passed through the ceiling opening from above the ceiling, Connect with the electrical components (not shown) in the frame through the outlet of the frame body (not shown in the figure).

In order to adapt the ventilation device to the installation of the integrated suspended ceiling, the length of the frame body flange 19 extending outward from the frame body opening is set to be relatively short. Proximity is such that the frame body flange 19 cannot pass through the ceiling opening and is tightly attached to the lower part of the ceiling. Joint 13 is passed through ceiling opening again until the flap of its joint plate 131 lower end is close to below the ceiling, and the perforation on the joint plate 131 lower end fold and the ceiling are penetrated upwards with screw from below the ceiling, thereby joint 13 is fixed on the ceiling; Then push the frame body 11 through the ceiling opening toward the roof until the frame body flange 19 is close to the ceiling. Snap on the outside of the frame body 11; then use screws to penetrate the opening on the frame body flange 19 and the ceiling, so that the frame body 11 is fixed on the ceiling, and finally cover the mask 12 on the frame body opening, so that the mask 12 covers the frame Body flange 19 and frame body opening.

As mentioned above, in order to adapt to the installation of the integrated suspended ceiling, the ventilating device needs to reduce the size of the frame body flange 19 and the face shield 12, but when the ventilating device is installed on a common suspended ceiling, the underside of the joint plate 131 and the flaps will be May protrude from the edge of the face shield 12, so that the frame flange 19 and the face shield 12 cannot fit closely with the ceiling, and the face shield 12 is lifted downwards (indoor side) from the ceiling, and a gap is generated between the face shield 12 and the ceiling to cause air leakage. Moreover, since the size of the ceiling opening cannot be set too large, there may not be enough space for the frame body 11, the joint plate 131 of the joint 13 and the power cord to pass through, so that the ventilation device cannot be installed on a common suspended ceiling.

The ventilating device 10 according to the embodiment of the present application can be applied to both integrated suspended ceilings and ordinary suspended ceilings through the above structure. The installation process of the ventilating device 10 will be described below.

Referring to FIG. 7 , when the ventilation device 10 is installed on a common suspended ceiling, a ceiling opening larger than the size of the frame opening K and smaller than the overall size of the frame bottom including the frame flange 23 is cut in advance on the ceiling C.

Next, make the joint 30 pass through the ceiling opening until the joint flange 32 at the lower end of the joint plate 31 is close to the below of the ceiling opening edge, at this time, the joint flange 32 and the protrusion 314 that is located on the joint plate 31 are close to the ceiling C. Since the ceiling C itself has a certain thickness, screws can be used to penetrate the long opening H and the side of the ceiling C, so that the joint 30 is fixed on the ceiling C. That is to say, there is no need to provide screw holes on the joint flange 32 to fix the joint 30 at the bottom of the ceiling C. The joint flange 32 only plays a positioning role for clamping the ceiling C during the installation of the joint 30. Therefore, the size of the joint flange 32 itself, that is, the length of the joint flange 32 extending from the lower end of the joint plate can be set shorter .

After the joint 30 is fixed on the ceiling C, the wiring 60 including the power line and the switch control line is passed through the ceiling opening from above the ceiling, and passes through the electrical component outlet 242 of the first side wall 221 of the frame body and the electrical component box The opening 253 on the body 251 is inserted into the electrical component box 25 . Under the guidance of the wiring channel 254, the wiring 60 passes through the opening 253 on the electrical component box body 251 and then tilts upwards. Therefore, even if there is liquid outside the frame body 20, it enters the electrical wiring along the wiring 60 through the electrical component outlet 242. The inside of the component box 25 also falls downward due to the force of gravity, and does not flow upward along the wiring 60 inclined upward. That is to say, by providing the wiring passage 254 , the risk of contact between liquid and electrical components can be reduced, thereby improving the safety of the ventilation device 10 .

Next, the wiring 60 is inserted into the opening of the water blocking wall 255 to be connected to the internal electrical components. Since the water retaining wall 255 is provided, even if liquid flows through the wiring channel 254 to the side of the internal electrical components, it can be blocked by the water retaining wall 255 and cannot contact with the internal live parts, thereby further improving the ventilation device 10. safety.

It is necessary to additionally reserve space for the power line, the switch control line and the connector plate 31 to pass through. Therefore, the size of the ceiling opening can be set closer to that of the frame body 20 , so that the ventilation device 10 that can be installed on the integrated suspended ceiling can also be smoothly installed on the ordinary suspended ceiling.

When the frame body 20 is pushed through the ceiling opening toward the roof, the guide rib 312 of the joint plate 31 is inserted into the installation space S from the lower end to the upper end, because the lower part of the guide rib 312 protrudes from the joint plate 31 The length is shorter than its upper part, so it is relatively easy to put the installation space S on the shorter lower part of the guide rib 312 protruding from the joint plate 31, plus it can slide along the guide rib inclined surface 315, slide to When the guide rib 312 is at the upper part, the upper part of the guide rib 312 protrudes from the joint plate 31 longer, so the guide rib 312 and the installation space S can be engaged more closely. That is to say, during the process of pushing the frame body 20 toward the roof, construction personnel can easily fit the installation space S of the frame body 20 outside the guide rib 312 of the joint plate 31 from below the joint plate 31, which improves the convenience of installation. sex.

When the frame body 20 continues to be pushed toward the roof, the inclined piece of the joint 30 is inserted into the recessed part 211 of the top wall 21 of the frame body. more simple.

After the frame body flange 23 touches the bottom of the ceiling C, the frame body flange recess 232 is located below the joint flange 32, that is, at this time, the joint flange 32 is inserted into the frame body flange recess 232, so that the joint flange 32 The upper surface of the frame and the upper surface of the frame body flange 23 are basically located on the same plane. The position corresponding to the joint flange 32 on the frame body flange 23 will not tilt downward due to being supported by the joint flange 32, and there will be no gap between the frame body flange 23 and the ceiling C, even if the construction personnel from the frame The bottom of the body flange 23 uses screws to penetrate the frame body flange screw hole 231 and the ceiling C so that the frame body 20 is installed on the ceiling C, and the frame body flange 23 will not be deformed by the joint flange 32 . After the housing 20 is attached to the ceiling C, the face mask 40 is attached.

Specifically, first connect the switch control wire drawn from the electrical component box 25 to the LED light module, and then hang the hook 431 of the mask 40 on the mask support portion 27 . Since the end of the mask support portion 27 is provided with a hook portion 271, the hook 431 can be caught by the hook portion 271 after being hung on the mask support portion 27, so it will not fall off from the mask support portion 27 easily. In this way, temporary fixation of the mask 40 can be realized, making the subsequent installation steps more convenient. Then, snap the engaging hook 44 of the mask 40 into the elongated fixing hole 245 of the first side wall 221 of the frame body, and pass through the screw hole of the mask and the screw column 264 of the snail shell 262 by screws, thereby fixing the mask 40 on the frame. body 20. That is to say, in this embodiment, the side of the mask 40 close to the first side wall 221 is fixed by the hook 44 , and the side close to the fourth side wall 224 is fixed by screws, thereby realizing simple and stable installation. Even if the mask 40 needs to be disassembled for maintenance in the future, after unscrewing the screws that pass through the screw holes 413 of the mask and the screw columns 264 of the snail shell 262, the mask 40 is also hung on the mask support part 27 and will not fall, preventing the mask from being damaged during construction. personnel, improving maintenance safety.
