Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a ventilation fan hood that is easy to assemble, and more specifically to a disposable type simple hood for ventilation fans installed in kitchens, cooking areas, etc.

[Conventional technology]

In order to improve the efficiency of the exhaust action by the ventilation fan and to prevent the upper part of the frame of the ventilation fan from getting dirty, a hood that covers the upper part of the ventilation fan and opens downward has been widely used. Conventional hoods of this type are usually formed by molding metal or plastic plates, and are attached to the upper part of the outer periphery of the ventilation fan using screws, making them extremely difficult to remove. This makes cleaning work extremely troublesome when it becomes dirty due to oily smoke.

Conventionally, in order to eliminate such inconveniences, as disclosed in, for example, Japanese Utility Model Application Publication No. 118316/1983, rectangular shapes were made using suitable bendable non-combustible plate materials such as thin aluminum plates. A vertically elongated substantially trapezoidal side piece is connected to the left and right ends of the cover through a fold, and a horizontally long rectangular upper piece is connected to the upper end through a fold. By bending the top piece at right angles to the rear of the cover along the respective folds and attaching it to the front of the ventilation fan by appropriate means, an opening is formed at the lower end surrounded by the cover, the side pieces, and the mounting wall of the ventilation fan. At the same time, the cover piece faces upward and is slightly inclined backward, and the upper surface is covered by the upper piece, so that it can be folded and assembled freely, and the lower opening surface has a reinforcing piece 3 and clamping pieces 7, 9. A simple hood is known in which a mounting groove 10 and a filter main body 11 can be fitted and mounted.

[Problem that the invention aims to solve] When assembling the hood three-dimensionally and attaching it to the ventilation fan, the upper edge of the side piece and the left and right edges of the upper piece can only be joined by abutting them perpendicularly. ,
A slit-like gap is created between both edges. As a result, outside air is sucked in from the gap, which of course reduces the suction power of the ventilation fan, and the oily smoke sucked in from the gap adheres to both the inside and outside of the gap, causing the hood to dry. Not only does it stain the inside and outside of the car, making it unsightly, but it is also undesirable from a sanitary standpoint. Furthermore, if the hood becomes more contaminated, there is a possibility that the attached oil droplets may even trickle down the side wall of the hood and drip from the lower end opening.

The present invention was developed to solve these problems.It can be sold in a folded state at stores, and it is an inexpensive and easy-to-install hood that can be assembled into a three-dimensional hood shape for ventilation fans. Although it is a disposable type hood, it has excellent suction ability for oil smoke, and when assembled, there is a
A hood with no gaps is created at the bent part of the circumferential side, and this creates a hood with no gaps.
To provide an easy-to-assemble ventilation fan hood that can prevent early soiling, can be used hygienically, and is easy to assemble.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail based on the drawings. As shown in FIGS. 1 to 3, 1 is an easy-to-assemble ventilation fan hood according to an embodiment of the present invention, and the hood 1 is made of thick aluminum foil (80μ),
It is made of a noncombustible sheet body 2 made by pasting together metal-deposited paper or aluminum foil and cardboard so that it can be assembled. That is, an inclined upper surface part 3 is formed in the center of the sheet body 2 so as to extend diagonally downward from above the ventilation fan A. In this embodiment, the inclined upper surface part 3 is divided into a rectangular top plate part 3a that covers the top surface of the ventilation fan A through a fold line 4, and a trapezoidal front part 3b that covers the front surface of the ventilation fan A. It is divided and formed. Further, an elongated hole 5 is bored in the top plate portion 3a so as to be able to engage with a locking metal fitting B attached to the top surface of the ventilation fan A. Furthermore, a flap 7 whose angle can be changed arbitrarily via a fold line 6 is formed at the lower end of the front portion 3b. Also,
At both ends of the top plate portion 3a of the inclined upper surface portion 3, truncated triangular side portions 9, 9 are formed to cover the side surfaces of the ventilation fan A via a fold line 8. Further, a flap 11 is formed at the lower end of the side surfaces 9, 9 along a fold line 10, as described above.

Thus, a triangular joint surface is formed between the side edges 12, 12 of the side surface portion 9 and the front portion 3b of the inclined upper surface portion 3 via the fold lines 13, 13 formed on the side edges 12, 12. 14 is formed. Further, a crease line 15 is formed at the center of the joint surface portion 14 so that the joint surface portion 14 can be folded in two.

Of course, the double-sided adhesive tape 16 may be provided near the joint surface fold line 15 on the side surface portion 9 side, and the bent seam surface portion 14 may be bonded to the back surface of the side surface portion 9.

When assembling the noncombustible sheet body 2 formed to be assembled as described above to form a hood for attaching to the ventilation fan A, the upper part 3a of the inclined upper part 3 and both side parts 9 are connected to each other. From the crease line 8 formed and the crease line 4 formed in the continuous portion of the top portion 3a and front portion 3b of the inclined upper surface portion 3, both side surfaces 9 and the front portion 3b of the inclined upper surface portion 3 are bent in the same direction. , and the joint surface part 14 formed between both side parts 9 and the front part 3b of the inclined upper part 3 is connected to the fold line 13 of the side part 9 and the front part 3.
Fold the joint surface 14 in half from the crease line 13 formed at the center of the joint surface portion 14 and overlap the seam surface 14 in half. A double-sided adhesive tape is attached to the back surface of the joint surface portion 14 by peeling off and pasting the silicone paper and folding the joint surface portion 14 in half toward the back side of the front surface portion 3b of the inclined upper surface portion 3. 16, the joint surface portion 14 is attached to the front surface portion 3b. Also, each flap 7, 11,
11 may be bent appropriately to a desired angle. Of course, if the flap is expanded outward, a higher smoke evacuation effect can be expected. In this way, one sheet body 2
From this, a hood 1 according to an embodiment of the present invention is assembled.

When attaching this assembled hood 1 to an existing ventilation fan A, a locking metal fitting B is attached to the top surface of the ventilation fan A, and the long hole 5 of the hood 1 is engaged with the locking metal fitting B, and the hood 1 The hood 1 is attached to the existing ventilation fan A by covering the outer surface of the ventilation fan A with the inclined upper surface part 3 and both side parts 9 of the hood 1. Of course, the lower part of the hood 1 is open. By using the ventilation fan A in this manner, a high smoke evacuation effect can be obtained.

Furthermore, since the hood 1 has a simple configuration, it can be easily assembled, attached to and removed from the existing ventilation fan A.

(Effects of the invention) As described above, the present invention is made of a single non-flammable sheet that can be assembled so that it can be easily installed on an existing ventilation fan without using any tools. It doesn't take much time and anyone can easily install it. Moreover, it is cheaper than conventional hoods made of plastic or steel plates.
Also, if it gets dirty, you can easily clean the hood by removing it, making it into a sheet, and wiping off the dirt. Also, it is constructed from a single noncombustible sheet body, and by bending the fold lines 4, 8, 8, 13, 13 and the fold lines 15, 15 of the joint surfaces 14, 14, there is a gap between each fold line. The sheet body 2 can be robustly assembled even if it is a relatively thin sheet body 2 without causing any formation of the sheet body 2, and has excellent suction power. As described above, the hood of the present invention is practically useful.
