Description

[Detailed description of the device] [Industrial applications]

The present invention relates to an improvement in a structure for attaching a ventilation port member for ventilating indoor air in a bathroom or the like.

[Prior art]

Conventionally, as shown in FIG. 4, a mounting structure 1 for a ventilation port member has a circular through hole 2a formed at an appropriate position on a ceiling 2, and a ventilation port member 3 is inserted into the through hole 2a to provide a circular ventilation. Mouth 3a in room A
The ventilation port member 3 is connected to the exhaust duct 4 on the outdoor B side.

[Problems to be solved by the device]

By the way, in the ventilation port member 3, since the ventilation port 3a is circular, it is necessary to provide the decorative plate 5 at the center of the ventilation port 3a so that the back side of the ventilation port 3a cannot be seen from the room A. However, the provision of the decorative plate 5 blocks a part of the ventilation port 3a, and therefore the ventilation port 3a needs to have a large diameter. for that reason,
In the conventional structure 1, the ventilation port member 3 having a large diameter is emphasized on the ceiling 2 and the appearance of the room A may be deteriorated. Furthermore,
The presence of the decorative plate 5 made it difficult to clean the ventilation port 3a. SUMMARY OF THE INVENTION In order to solve the above problems, the present invention aims to provide a mounting structure for a ventilation port member having a ventilation port as a long hole.

[Means for Solving the Problems]

The feature of the means adopted by the attachment structure of the ventilation member according to the present invention (hereinafter referred to as "the structure of the present invention") is that the ventilation member is inserted into the room through the through hole formed in the ceiling. And a ventilation box of the ventilation port member, which is connected to the ventilation port of the ventilation port member, is provided with a joint with an exhaust duct, and the ventilation port of the ventilation port member has a narrow opening width. That is, it was formed into a long and slender hole having a long length.

[Action]

Since the ventilation port is a long hole, the back side of the long hole is difficult to see, and it is not necessary to provide a decorative plate, which has been conventionally required. As a result, the ventilation port has no obstruction to cleaning, and the opening area is the minimum necessary and has the shape of a long hole, so that its presence does not give an uncomfortable impression to the indoor user. As a result, the structure of the present invention does not impair the aesthetics of the room. Since the ventilation hole of the long hole communicates with the collecting box, it sucks indoor air in the whole area. The sucked indoor air passes through the air collection box, is guided to the exhaust duct, and is discharged to the outside of the room.

【Example】

The structure of the present invention will be described below based on the embodiment shown in FIGS. The proposed structure 11 includes a ventilation port member 13 inserted into a long through hole 12a of a ceiling 12 and an air collection box 16 provided on the ceiling back side B side. The ventilation port member 13 is formed of a synthetic resin material or the like, and the ventilation port 13a is formed in a long hole.
A flange-like flange portion 13b is formed on the opening peripheral edge portion on the room A side to cover the opening peripheral edge portion 12b of the through hole 12a, and locking claws 13d and 13d are provided on the cylindrical portion 13c inserted into the through hole 12a. Is formed. The air collection box 16 is formed of a stainless steel plate or the like, a bottom plate 16a, a joining cylinder 16b extending from the bottom plate 16a and fitted into the cylinder portion 13c of the ventilation port member 13, and a peripheral portion of the bottom plate 16a. The upper part of the box, which is joined 20 with the sealing material 22 with screws etc.
16c and the exhaust duct joint that protrudes from the proper place on the upper part 16c of the box
It consists of 16d. The joining cylinder 16b of the air collection box 16 has a locking claw 13d formed on the cylinder portion 13c of the ventilation port member 13 which is the mating side.
Engagement openings 16e that engage with are formed at corresponding locations. The air collection box 16 has a mounting reinforcement member 17 arranged on the ceiling back B of the ceiling 12,
They are joined 21 with screws using the mounting pieces 18, 18. A spacer 19 for height adjustment is sandwiched between the mounting reinforcing member 17 and the mounting piece 18 as needed. The exhaust duct 24 is joined to the exhaust duct joint portion 16d of the air collection box 16. The structure 11 of the present invention configured as described above has the ventilation hole 13a having a long hole.
Since the entire area of the opening communicates with the collection box 16, the ventilation port 13a
The room air is sucked in all over the area. The sucked indoor air is
After passing through the air collection box 16, it is guided to the exhaust duct 24 and discharged to the outside of the room. Next, a procedure for constructing the proposed structure 11 will be described. First, the pre-assembled air collecting box 16 is attached to the mounting reinforcing member 17 using the mounting pieces 18, 18.
Join with screws 21 and 21. At the time of this joining, the joining cylinder 16b of the air collection box 16 and the through hole 12a of the ceiling 12 are aligned. Next, the exhaust duct 24 is joined to the exhaust duct joining portion 16b of the air collection box 16. Then, the flange portion 13 of the ventilation port member 13
The sealing material 23 is applied to the back side of b and the tip of the tubular portion 13c to prepare, and the tubular portion 13c of the ventilation port member 13 is inserted into the through hole 12a of the ceiling 12 from the room A side, and the inserted tubular portion 13c is inserted. Collection box
The fitting work is completed by fitting the fitting cylinders 16b into 16 and engaging the locking claws 13d of the ventilation port member 13 with the corresponding engagement ports 16e of the air collection box 16.

[Effect of device]

As described above in detail, the structure of the present invention has the following practical effects. The ventilation port does not need to be provided with a decorative plate, which has been indispensable in the past, and therefore has no obstacle to cleaning. As a result, the proposed structure can easily clean the ventilation port. Since the ventilation opening has a minimum opening area and is in the shape of a long hole, its presence does not give an uncomfortable impression to indoor users. As a result, the proposed structure does not impair the aesthetics of the room.
