Description

  The present invention relates to a hood (hood cover) of an exhaust port on the outer wall side of a passage for exhaust of an exhaust fan.

Conventionally, a hood is attached so that rainwater, dust or the like does not enter the exhaust port on the outer wall side. (For example, as shown in Patent Document 1.)
Japanese Patent Laid-Open No. 9-79627 (Abstract, FIGS. 1 and 2)

Conventional hoods are made of metal or plastic plates. Metal objects are rusted or corroded by rainwater, especially acid rain and automobile exhaust gas, and are damaged and dirty, resulting in a short life and a loss of aesthetics.
Plastic products are severely degenerated by sunlight, etc., and cracks, etc., have a short lifespan, which also impairs aesthetics.

  It is a hood that covers the exhaust port on the outer wall side of the house with the exhaust passage of the ventilation fan. The inner surface side is made of metal or plastic, and the outer surface side is covered with ceramics or glass.

  A hood that covers an exhaust port on the outer wall side of a house with an exhaust passage of a ventilation fan, and at least a collar portion is made of metal or plastic on the inner surface side and covered with earthenware or glass on the outer surface side.

Since the surface of the hood according to the present invention is covered with earthenware or glass, it has an aesthetic appearance without being eroded by rainwater or outside air.
Also, the back side of the pottery or glass jacket is covered with a metal plate or plastic plate and bonded and fixed, so even if any object hits the pottery or glass jacket, it will fall off There is nothing.

  The hood 1 shown in FIG. 1 has a plurality of through holes 3 provided on a flat plate 2 made of earthenware, and a metal plate 5 provided with through holes 6 corresponding to the through holes 3 is contacted and fixed to the back surface of the flat plate 2. Thus, through holes 4 for attachments such as screw nails are provided corresponding to at least the four corners of the flat plate 2 and the metal plate 5.

The hood 1a shown in FIG. 2 is one in which the edge of a ceramic flat plate 2a covers the edge of a metal plate 5. It is preferable to provide a flange 7 on the upper edge of the flat plate 2a when attached to the exhaust port on the outer wall side.
The trough 7 is preferably provided also on the flat plate 2 of the hood 1. Prevents rainwater from dredging 7 from entering the exhaust through the through holes 3 and 4.

The ceramic flat plates 2 and 2a are preferably colored or patterned.
A synthetic resin plate may be used instead of the metal plate 5.

  The hood 1 and the hood 1a cover the outer wall side exhaust port and come into contact with the outer wall, and are screwed in and fixed.

  The metal plate 5 is a conventional flat-plate metal or synthetic resin hood, and a ceramic or glass plate 2 corresponding to the hood is formed, and the hood and the plate 2 are bonded and fixed. May be.

The hood shown in FIG. 3 is a conventional circular hood 9 with a ridge 8.
The hood 9 has an outer flange portion 11 in a cylindrical portion 10 to be inserted into an exhaust port, a crosspiece 12 is provided in the cylindrical portion 10, the cylindrical portion 10 is fitted into the exhaust port, and the flange portion 11 is exhausted. The screw is brought into contact with the edge of the mouth and screwed into the screw hole 13 of the flange 11 to be fixed.
Instead of the crosspiece 12, a lattice, a punching plate, or a net may be used.

  4 is a ceramic or glass cover 14 that covers the surface of the flange 8 and the flange portion 11 of the conventional hood 9, and the flange portion 15 corresponding to the flange portion 11 of the hood 9 and the hood 9. It has a flange 16 that can cover the flange 8, has a through hole 17 corresponding to the through hole of the cylindrical portion 10 of the hood 9, and is screwed into the flange portion 15 corresponding to the screw hole of the flange portion 11 of the hood 9. It has a hole 18.

The cover 14 is provided with an adhesive layer on the surface of the hood 9 or on the inner surface side of the cover 14, and the cover 14 is covered from above the hood 9. The flange portion 15 is on the flange portion 11 and the flange 16 is on the flange 8. The screw hole 18 is made to correspond to the screw hole 13 and bonded by heating or pressurizing.
As a result, the inner surface of the cover 14 is lined with a metal plate or a synthetic resin by the hood 9, presents an aesthetic appearance, and even if the cover 14 is broken for some reason, a piece of earthenware or glass may fall off. Absent.

  Since there are various shapes of conventional hoods, the surface of the buttock or the part visible from the outside is covered with ceramics or glass.

  In any of the embodiments described above, the ceramic or glass cover may be an integral cover, or may be divided into a plurality of parts and sequentially applied to the surface of the metal or plastic hood. They may be used after being joined together.

The method of lining a ceramic or glass cover with a conventional hood is not limited to the above method. For example, the following method can be used.
That is, an adhesive layer is provided on the surface of a hood selected from various conventional hoods, coated with porcelain earth or glass material, screw holes are provided, and heated and quenched.
When applying the porcelain clay or glass material, the edges of the hood or flange of the conventional hood are wrapped with porcelain earth or glass material, and the baked ceramic cover is firmly fixed to the hood.

It is a perspective view of a hood. It is sectional drawing of the food | hood of other embodiment. It is a perspective view of the conventional hood. It is a perspective view of the ceramic or glass cover for food.
