SOLUTION: A hood main body 21 is fitted on the indoor-side surface of a wall 1 and an outdoor hood 3 is fitted to the peripheral edge part of a through hole 11 in the outdoor-side surface of the wall 1. Next, a duct main body 51 is inserted into the through hole 11 from the outdoor side and a fitting plate 6 is pressed on the indoor-side surface of the wall 1. Thereby the part of a door 53 in the fore end of the duct main body 51 is made to project into the outdoor hood 3 and connected therewith and, at the same time, the lower end of a connecting tube 52 comes into contact with an outlet 22 of a range hood 2, so that the connecting tube 52 and the outlet 22 be connected. After the duct main body 51 of a duct member 4 is inserted from the outdoor side into the through hole 11 provided in the wall 1 and the fitting plate 6 is pressed on the indoor-side surface of the wall l so that the duct member 4 be fitted, in this way, the indoor side and the outdoor side are cut off from each other by an airtight material 7 fitted on the indoor side of the fitting plate 6.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an exhaust duct mounting structure and a duct member used for the mounting structure.

[0002]

2. Description of the Related Art Conventionally, as described in Japanese Utility Model Publication No. 3-52433, a range hood is usually provided above a range installed in a kitchen room or the like. The range hood is connected to an exhaust duct passing through a through hole in the wall, and the exhaust duct is connected to an outdoor hood provided outdoors. Then, the ventilation fan installed in the range hood or the exhaust duct is operated, and the exhaust gas generated from the range and smoke generated from the cooked food placed on the range are collected by the range hood and discharged outside. Things.

If the space between the exhaust duct and the through hole provided in the wall is open, indoor air comes in and air from the outside enters from this portion, so that even if indoor air conditioning is inefficient, outdoor air is inefficient. Loudness is poor due to noise. Therefore, the space between the exhaust duct and the through hole is usually closed with a heat-resistant adhesive tape such as an aluminum tape or a putty or the like is filled to close the space between the exhaust duct and the through hole.

[0004]

However, if the space between the exhaust duct and the through hole is closed with aluminum tape or the like and putty is packed, there is a problem that the appearance is poor. In addition, the through-hole is often provided near the ceiling in order to pass an exhaust duct that exhausts exhaust gas and the like from the range from above a range hood provided above the range. Therefore, the work for closing the gap between the exhaust duct and the through hole is performed near the ceiling, and is difficult to perform. Further, even if the work is performed, since the work is performed in a narrow place, there is a problem that the work is complicated, the dispersion is large, and sufficient airtightness cannot be obtained. Accordingly, an object of the present invention is to provide a mounting structure of an exhaust duct which can be easily constructed and can be reliably airtightly closed, and a duct member used for the mounting structure.

[0005]

Means for Solving the Problems The present invention has been made to achieve the above object, and the invention according to claim 1 penetrates a through hole provided in a wall and is provided indoors on the wall. A mounting structure of a cylindrical exhaust duct connecting the range hood and an outdoor hood provided outdoors on a wall, wherein a mounting plate provided on an outer peripheral surface of the exhaust duct has a through hole on the indoor side of the wall. The peripheral portion is covered, and the space between the indoor side surface of the wall and the mounting plate is closed with an airtight material.

According to a second aspect of the present invention, there is provided a cylindrical exhaust duct, a plate-shaped mounting plate provided on the outer peripheral surface of the exhaust duct on the indoor side at a substantially right angle to a cylinder axis of the exhaust duct, and And an airtight material provided around the exhaust duct on the outdoor side surface. The airtight material used in the present invention may be any material as long as it can close the gap between the indoor side surface of the wall and the mounting plate, but is soft when it is constructed like a putty. At times, it is deformed into a shape according to the gap between the indoor side of the wall and the mounting plate, and it is hardened as it is after this work, or it is pressed at the time of construction, such as rubber or synthetic resin foam, etc. It is preferable to deform to a shape corresponding to the clearance between the mounting plate and the mounting plate and to seal the space between the indoor side surface of the wall and the mounting plate because the airtight sealing can be easily achieved.

In the first aspect of the present invention, the space between the indoor side surface of the wall and the mounting plate is closed by the airtight material. , An airtight material may be provided, and a mounting plate may be pressed down on the airtight material to be mounted thereon. However, the airtight material is provided on the mounting plate as in the invention of claim 2, and the mounting plate is attached to a wall. It is preferable to install it on the indoor side because it is easy to construct.

According to the first aspect of the present invention, since the mounting plate provided on the outer peripheral surface of the exhaust duct covers the periphery of the through hole on the indoor side of the wall, when viewed from the indoor side, the through hole and The surrounding area is blocked by the mounting plate and cannot be seen. In addition, since the space between the indoor side surface of the wall and the mounting plate is closed by the airtight material, the indoor and the outdoor are shut off by the airtight material, and the indoor air goes outside or the outdoor air goes inside. It is easy to air-condition indoors and there is no outside noise, so that it is comfortable.

According to the first aspect of the present invention, in the construction method for providing a structure for closing between the exhaust duct and the through hole, an airtight material is provided around the through hole on the indoor side surface of the wall, and the airtight material is mounted thereon. It is only necessary to hold down the board and attach it, or to provide an airtight material on the attachment board and attach this attachment board to the indoor side of the wall.

The duct member according to the second aspect of the present invention includes a cylindrical exhaust duct, a plate-like mounting plate provided on the outer peripheral surface of the exhaust duct on the indoor side at a substantially right angle to a cylinder axis of the exhaust duct,
Since the airtight material provided around the exhaust duct is provided on the outdoor side surface of the mounting plate, this duct member is inserted from the indoor side into the through hole provided in the wall, and the mounting plate is pressed against the indoor side surface of the wall. Just attach the duct member and the airtight material attached to the mounting plate will adhere to the indoor side of the wall,
The mounting plate and the indoor side of the wall can be closed.
