Description

[Detailed Description of the Invention] The present invention relates to a filter cover for a ventilation fan that is formed from an aluminum sheet.

BACKGROUND OF THE INVENTION Ventilation fans installed in kitchens, dining rooms, restaurants, and other cooking rooms in ordinary homes quickly become contaminated due to the influence of oil, steam, smoke, etc., and need to be cleaned regularly. Moreover, as is well known, this cleaning work is extremely troublesome, and the reality is that the equipment is left in a dirty state for a long period of time.

In order to solve this problem, a simple filter cover for ventilation fans has recently been proposed, but conventional filter covers consist of a filter surface facing the front of the ventilation fan and a side surface that abuts the side of the ventilation fan. Since it is manufactured in a box shape, it is extremely bulky, making it extremely difficult to pack, package, or transport, and the distribution cost is higher than the production cost.
As described in Publication No. 37484, a filter cover for a ventilation fan made of a single piece has been devised, but because the front part is open to the front, the strength of the part where the filter is attached is extremely low. , cannot withstand long-term use,
Furthermore, since it is simply attached to the ventilation fan, there is a problem in that the mounting strength is reduced.

The purpose of this invention is to solve the above problems by providing a filter cover for a ventilation fan made of aluminum sheet, which is essentially flat and can be packaged by stacking multiple sheets together, and which can be folded very easily into a three-dimensional frame when in use.

The attached drawings show an embodiment of the present invention, in which reference numeral 1 indicates a rectangular front section located opposite to the front surface of the ventilation fan, and reference numeral 2 indicates a side section that comes into contact with the circumferential side of the ventilation fan frame. The front part 1 is mostly open and has a mounting and holding part 4 for a filter 3 on its outer periphery, and a lattice-like reinforcing strip 5 is formed in the open part. The side surface portion 2 is formed to extend in the form of a flap from each side of the rectangular front surface portion 1, and a large number of ridge-like or wavy uneven surfaces 6 are formed in the extending direction. The central edge of the uneven surface 6 of the upper side surface 2 has a smooth surface 7 to form an adhesive during installation, which will be described later, and the edge of the lower side surface 2 has a flat edge 8 on the uneven surface. It is formed to extend further from 6 and can be bent and brought into contact with the wall of the building when installed. Also, one side end 2 of the uneven surface 6
A has a tongue piece 9, and the other side face 2B has a flat part 10.
is formed, and when each side surface portion 2 is bent at a substantially right angle with respect to the front surface portion 1, each tongue piece 9 is superimposed on the back surface of each flat surface portion 10, 10, and is bonded with adhesive tape, for example. It is becoming possible to do so. In the figure, reference numeral 11 denotes a striation provided at the boundary between the front part 1 and the side part 2.

In this way, the filter cover for a ventilation fan according to the present invention has a rectangular front part 1 with a filter 3 in the ventilation opening and an outer peripheral edge of the front part 1 on the same plane made of one aluminum sheet. The filter attachment holding part 4 is connected to the filter attachment holding part 4, and the side surfaces 2, 2, 2 are connected to the circumferential side of the ventilation fan which is connected to the four peripheries of the filter attachment holding part 4 via the bending stripes 11. , 2 and a tongue piece 9 protruding from one end of these side parts 2 are formed into a flat state,
A reinforcing strip 5 is integrally formed in the open part of the front part 1, and a flat edge 8 is provided at the lower edge of the lower side part 2 to be adhered to the ventilation fan mounting wall surface 15. Since the product is a product, a predetermined number of products, for example 10 products, can be polymerized to form a package, and the form at the distribution stage such as packaging and transportation can be made extremely compact without being bulky. Therefore, packaging costs and transportation costs can be significantly reduced, and a desired number of sheets can be purchased in bulk and used one after another without requiring much storage space. Furthermore, since it is made of an aluminum sheet and has bending stripes 11, it can be easily bent into a frame shape when in use, and it is lightweight, so it can be attached to the ventilation fan frame, for example, by As shown in FIG.
The aluminum sheet piece 13 with the adhesive part 12 facing outward is bent into a hairpin shape and inserted into the rear edge of the upper surface of the ventilation fan frame 14, and the smooth surface 7 of the bent side part 2 is placed on the adhesive part 12. This can be easily done by pressing the flat edge 8 of the lower side surface 2 outward, bringing it into contact with the wall surface 15, and fixing it with adhesive tape. do. Further, according to the present invention, since the reinforcing strips 5 are provided on the front face part 1 which has a large opening, the strength of the filter mounting part can be increased and it can be used for a long period of time. Since the lower edge is provided with a flat edge 8 that is adhered to the ventilation fan mounting wall surface 15, the filter cover can be attached reliably and firmly.

It should be noted that the size of the front part 1 is formed to correspond to the size of a commonly used ventilation fan, and it goes without saying that there are no particular limitations on the mounting means during use.
