Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a sheet for preventing dirt on the wall surface around a ventilation fan.

[Prior Art] Air taken into a ventilation fan contains a considerable amount of dust and oil. Therefore, dust and oil droplets adhere to the area around the ventilation fan on the wall where the ventilation fan is installed at a considerable density, and when the situation becomes severe, oil droplets mixed with dirt may even drip from the wall surface. be. Therefore, in order to keep the area around the ventilation fan clean, it is necessary to clean it frequently.

In order to solve the above problem, a panel has been proposed that is attached around the ventilation fan body so as to spread outward from the ventilation fan in order to prevent dirt from adhering to the wall surface around the ventilation fan. This dirt prevention panel is usually made of relatively thick aluminum foil, and is attached to the ventilation fan using adhesive tape or magnets.

[Problems to be solved by the invention] However, the above-described dirt prevention panel is attached to the ventilation fan so as to spread around the ventilation fan body. Therefore, a space exists between the stain prevention panel and the wall surface around the ventilation fan,
Dust, oil droplets, etc. that have passed around the outside of the panel still adhere to the wall surface around the ventilation fan. Afterwards,
Although this prevents the walls around the ventilation fan from getting dirty to some extent, the walls still have to be cleaned at a certain frequency.

In addition, since it is installed so as to spread around the ventilation fan, shape retention is required. Therefore, it has to be constructed from a material having a certain thickness, which poses a problem of high product cost.

On the other hand, in order to prevent dirt from adhering to the wall surface around the ventilation fan, some people have pasted a thin sheet similar to wallpaper to the wall surface. However, although the ventilation fan has a substantially rectangular outer circumferential shape, the size varies considerably depending on the model. Therefore, it was necessary to hollow out or cut the thin sheet to match the ventilation fan in question.

Therefore, an object of this invention is to provide a dirt-preventing sheet that can be easily applied to various ventilation fans and that can reliably prevent dirt from adhering to the wall surface surrounding the ventilation fan.

[Means for solving the problem] This invention provides a sheet having a substantially rectangular outer circumferential shape for preventing dirt on the wall surface on which a ventilation fan is attached, and which are combined with each other to cover the outer circumference of the ventilation fan. comprising first and second sheets forming an opening that matches the shape, each of the first and second sheets having a corner portion having an inner angle substantially the same as an outer circumferential corner portion of the ventilation fan; The stain-preventing sheet is characterized in that the sides forming the corner portions have the same length as the outer peripheral piece of the ventilation fan or are made longer than the outer peripheral piece.

[Function] In this invention, first and second sheets are used which have corner portions having substantially the same inner angle as the outer circumferential corner portion of the ventilation fan. Further, the sides forming the corner portions of each sheet are formed to have the same length as the outer periphery of the ventilation fan or to be longer than the outer periphery. Therefore, by attaching the corner portions of the first and second sheets to the wall surface so as to match the outer peripheral corner portions of the ventilation fan, openings that match the outer peripheral shape of a ventilation fan of any size can be formed in the first and second sheets. It can be formed from a sheet of Therefore, it is possible to reliably prevent the wall surface around the ventilation fan of any size from becoming dirty.

[Description of an embodiment] Fig. 1 shows a state in which a dirt prevention sheet according to an embodiment of this invention is attached around a ventilation fan. Here, a first sheet 1 and a second sheet 2 are combined and pasted on a wall surface around a ventilation fan 3. As shown in FIG. 2, the first sheet 1 and the second sheet 2 are formed with corner portions 4 and 5 having substantially the same inner angle as the outer circumferential corner portion of the ventilation fan. Moreover, the pieces 4 forming the interior angles 4 and 5
As shown in FIG. 1, a, 4b, 5a, and 5b are formed longer than the outer periphery of the target ventilation fan 3. However, it may be formed to have the same length as the outer periphery.

Therefore, by moving each sheet 1, 2 in the direction shown by arrow A in FIG.
The size of the opening formed can be varied. As an example, a state in which the second sheet 2 is moved in the direction of arrow A is shown by a dashed dotted line B.

Therefore, by moving in the direction of arrow A in FIG. 2, it is possible to form an opening that matches a ventilation fan of any size having a substantially rectangular outer circumferential shape, and to reliably cover the wall surface around the ventilation fan. .

Note that in this embodiment, the first sheet 1 and the second sheet
The sheet 2 has the same shape. Therefore, just by using two sheets of one type, it can be adapted to a ventilation fan of any size. However, the first sheet 1 and the second sheet 2 are
They do not necessarily have to be formed in the same shape.

Furthermore, the outer peripheral edges 7a, 7b, 8a, 8b of the overlapping portion of the first sheet 1 and the second sheet 2
are formed parallel to a straight line (indicated by an imaginary line C) connecting the corner portion 4 of the first sheet 1 and the corner portion 5 of the second sheet 2, respectively. Then,
Even when the first sheet 1 and the second sheet 2 are moved in the direction of arrow A, steps are not generated on the outer periphery of the overlapping portion. However, if the appearance is not much considered, the outer peripheral edges 7a, 7b, 8a, 8b do not necessarily need to be formed parallel to the imaginary line C.

The first sheet 1 and the second sheet 2 can be attached to the wall surface around the ventilation fan by pasting them with adhesive tape or the like, or by magnetically attaching them using a magnet. To match the outer circumferential shape of the ventilation fan, first fix the corner of one sheet so that it matches the outer corner of the ventilation fan.
Next, the other sheet may be slid until it matches the other outer peripheral corner of the ventilation fan, and then fixed.

In the case of attaching with an adhesive, the entire or part of the back surfaces of the first sheet 1 and the second sheet 2 may be treated with adhesive, or double-sided tape or adhesive may be applied. It may be installed by applying it at the time of installation.

In addition, when attaching magnetically, iron pieces are attached to the surface side of the parts X and Y (see Figure 2) where one sheet overlaps the other sheet, taking into consideration the movable amount. A magnet may be fixed to the back side of the X and Y portions using an adhesive or the like.

Note that the first sheet 1 and the second sheet 2
The ventilation fan may be made of any material, but if the ventilation fan is installed near a cooking area, it is preferable to use a sheet containing a noncombustible material such as aluminum or iron. However, it does not necessarily have to be made of non-combustible or flame-retardant materials.

Regarding the relationship between material and mounting dimensions, when the sheet is made of relatively soft materials such as thin aluminum foil, resin film, or paper, it is preferable to use adhesive or adhesive tape for installation; When the sheet is made of a material, it may be attached magnetically or with an adhesive or the like.

[Effects of the invention] This invention is provided with first and second sheets that are combined with each other to form an opening that matches the outer circumferential shape of the ventilation fan, and each sheet has a corner portion of the outer circumference of the ventilation fan and an opening that matches the outer circumferential shape of the ventilation fan. Corner parts with approximately the same internal angle are formed, and the piece forming the corner part is the same length as or longer than the outer circumferential piece of the ventilation fan, so it can be easily adapted to any size ventilation fan. It is possible to adapt the ventilator to the ventilation fan, and to reliably cover the wall surface around the ventilation fan.

Therefore, there is no need to perform complicated work such as hollowing out or cutting according to the size of the ventilation fan, and there is no need to frequently clean the wall surface around the ventilation fan.
