Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a mounting structure for mounting a ventilation fan on a wall.

[0002]

2. Description of the Related Art Normally, when mounting a ventilation fan, a ventilation fan frame 20 and a weather cover 21 that match the size of the ventilation fan are obtained, and the ventilation fan frame 20 is fitted and fixed in a hole 23 formed in a wall 22.

However, in the above-mentioned mounting structure, since the ventilation fan frame and the weather cover are independent, and they are manufactured by different manufacturers with appropriate dimensions, the standards are not unified. Since it is necessary to make holes in the wall, and the ventilation fan frame and the weather cover must be installed separately, it is necessary to align both, and the work becomes complicated, and different parts manufactured by different manufacturers are assembled from ordering. It is complicated to manage and the wall thickness varies according to the specifications of the building. Therefore, there is a problem that it is necessary to prepare various types of ventilation fan frames with different lengths. The present invention has been made to solve the above problems, and by setting a variable length ventilation fan frame and a weather cover as a set, the work of installing the ventilation fan and the management from ordering to assembly of the parts are simplified. ,
Moreover, it is an object of the present invention to provide a ventilating fan mounting structure capable of coping with one type of ventilating fan frame even if the wall thickness is different depending on the building specifications.

[0004]

In order to solve the above-mentioned problems, a ventilation fan mounting structure according to the present invention mounts a ventilation fan frame in a hole formed in a wall, a weather cover is provided outside the ventilation fan frame, and a ventilation fan is provided inside the ventilation fan frame. In the ventilation fan mounting structure for attaching a guide frame that is fitted into the hole formed in the wall in the weather cover, the guide frame is slidably fitted to the guide frame to form a variable length fan frame. It is characterized by adopting a configuration in which a ventilation fan is attached to the inner end side of this ventilation fan frame.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of a ventilation fan mounting structure according to the present invention will be described below with reference to the drawings.

1 to 6, reference numeral 1 denotes a weather cover, which is formed into an elbow type as is well known, and is attached to the outside of a ventilation fan frame, which will be described later, to shield the upper side and the front side of the exhaust port to exhaust port. In order to prevent wind and rain from being blown in, this weather cover 1 has a guide frame 4 which is fitted inside the hole 3 formed in the wall 2 as shown in FIG.
A flange 5 attached to the wall 2 is provided on the outer periphery, and a required number of attachment holes 6 are formed in the flange 5 as shown in FIG. 3, and a seal member 7 is attached to the wall side of the flange 5 as shown in FIG. The weather cover 1 is manufactured by pressing a metal plate or molding a synthetic resin.

1 to 6, reference numeral A indicates the guide frame 4 slidably fitted to the inside of the guide frame 4 as shown in FIGS. 1 to 5, or as shown in FIG. 2 shows a ventilation fan frame having a variable length, which is composed of an adjusting frame 8 slidably fitted to the outside of the adjusting frame 8 and the adjusting frame 8 is provided with the adjusting frame 8.
When it is pushed so that the fitting becomes deeper, its length becomes shorter as shown in Fig. 4 to fit the thin wall 2, and when it is pulled out so that the fitting becomes shallower, the length becomes longer as shown in Fig. 5. To accommodate the thick wall 2. Then, as shown in FIG. 6, when the adjustment frame 8 is fitted to the outside of the guide frame 4,
A seal member 9 is provided between the guide frame 4 and the adjustment frame 8 so that the exhaust gas does not enter the wall 2 through the gap between the adjustment frame 8 and the guide frame 4.
The adjustment frame 8 that constitutes the ventilation fan frame A is also manufactured by welding a pressed sheet metal or by molding a synthetic resin. As shown in FIG. 3, an electrical insulating tape 10 is attached to the outer periphery of the electrical insulating tape 10.

1 to 6, reference numeral 11 denotes a screw as a member for connecting the guide frame 4 and the adjusting frame 8 which constitute the ventilation fan frame A, and is shown in the middle of both side walls of the adjusting frame 8. 3, a hole 12 opened as shown in FIG. 3 and a long hole 13 formed long in the direction in which the adjustment frame 8 slides on the guide frame 4 as shown in FIG. When the nut 14 is screwed to connect the guide frame 4 and the adjustment frame 8 and the length of the ventilation fan frame A is adjusted to the thickness of the wall 2 by sliding the adjustment frame 8, the screw 11 is tightened to tighten the ventilation fan. The length of the frame A is fixed, and the electrical insulating washer 15 is inserted between the frame A and the hole 12. By using the screw 11 as the connecting member, the guide frame 4 and the adjusting frame 8 can be connected and the length of the ventilation fan frame A can be fixed as described above.
However, if the adjustment frame 8 is fitted and placed on the guide frame 4, the two do not separate from each other, and the sliding of the adjustment frame 8 causes the ventilation fan frame A to move.
If the weather cover 1 and the adjustment frame 8 are fixed to the wall 2 after the length is determined, the screw 11 may not be used.

In FIGS. 2 and 3, reference numeral 16 denotes a nut pocket attached to the outside corresponding to the elongated hole 13 of the guide frame 4, which is formed to be slightly longer than the elongated hole 13 and placed. When the nut 14 is movably accommodated therein, the length of the ventilation fan frame A can be freely adjusted, but the nut 14 does not fall off during transportation, handling, assembly, or the like. And convenient.

In FIG. 1, reference numeral 17 shows a retaining member for the ventilation fan 18 provided inside the upper piece of the adjusting frame 9, and some irregularities are provided at a predetermined interval and the ventilation fan 18 is placed above the ventilation fan 18. The tip of the mounting screw 19 provided on the above is engaged and placed as shown in FIG. 1 so that the ventilation fan 18 does not separate from the ventilation fan frame A due to its vibration. Alternatively, a configuration in which some sets of embossings or holes are provided at intervals that match the set screw 19 may be adopted.

Next, a mounting state of the ventilation fan according to the above-described embodiment of the ventilation fan mounting structure will be described.

First, a hole 3 for accommodating a guide frame 4 is made in a wall 2 on which a ventilation fan 18 is to be attached, and a ventilation fan frame A composed of a guide frame 4 and an adjusting frame 8 is formed in this hole 3 as shown in FIG.
Fit in. And the flange 5 of the weather cover 1
Is attached to the outside of the wall 2 with a screw or the like, and then the adjustment frame 8 fitted in the guide frame 4 is pulled out when retracted from the inner surface of the wall 2, and pushed when pushed out to align the adjustment frame 8 with the inner surface of the wall, If the length of the ventilation fan frame A is fixed by tightening the screw 11, the ventilation fan 18 is housed inside the adjustment frame 8 and is fixed to the adjustment frame 9 with the set screw 19, the attachment of the ventilation fan 18 can be performed easily and in a short time. be able to.

As described above, in the ventilation fan mounting structure according to the present invention, the ventilation fan frame of variable length and the weather cover are set, so that the mounting work of the ventilation fan and the management from ordering to assembling of parts are simplified. In addition, even if the wall thickness varies depending on the specifications of the building, one type of ventilation fan frame can cope with this.
