Description

[Detailed description of the invention] Technical field This invention is a structure of a filter cover that is attached to the intake side of an intake device such as a ventilation fan or a range hood to collect pollutants in the air that is being circulated. Regarding improvements.

Prior Art FIG. 8 is a perspective view for explaining an example of a conventional filter cover for a ventilation fan. This ventilation fan filter cover 1 consists of a cylindrical cover body 2 made of a synthetic resin molded product, and a filter member 4 attached to cover the ventilation opening 3 of the cover body 2, as shown in the figure. It is configured to be attached to the intake side of the ventilation fan 5. However, since the cover body 2 is a synthetic resin molded product, it cannot be used arbitrarily for ventilation fans 5 of different sizes, and therefore various cover bodies 2 must be prepared depending on the type of ventilation fan. There was a problem. Furthermore, since the cover body 2 is a synthetic resin molded product, it has a considerable thickness, resulting in poor packaging efficiency and the need for a larger space for display in stores.

As a filter cover that solves the above-mentioned problems, a ventilation fan filter cover 11 as shown in a perspective view in Fig. 9 was developed in U.S. Pat.
Disclosed in No. In this ventilation fan filter cover 11, the cover body 12 is made of a flat aluminum sheet. Then, with the filter member 14 pasted so as to cover the ventilation opening 13 of the cover body 12, it is attached to the intake side of the ventilation fan 5 as shown in FIG. By bending the surrounding side surface portion 17 via the strip 16, it is possible to align it along the ventilation fan 5. Moreover, this ventilation fan filter cover 11 has a cover main body 12.
As mentioned above, since it is made of a single aluminum sheet, it can be bent, so it can be made into a flat plate shape when packaging, which improves packaging efficiency and the display at the top. It is possible to save space.

However, in some ventilation fans, the central motor portion or rotating blades protrude more than the other surface on the intake side. Therefore, if the filter cover 11 is attached to this type of ventilation fan, the cover body 12 or the filter member 14 will come into contact with the motor or the rotating blades. Therefore, the filter cover 11 shown in FIG. 9 could not be used in this type of ventilation fan. In addition, some ventilation fans have quite large suction power, and when the filter cover 11 is used for such models, the cover body 12 is made of one aluminum sheet, so the center of the cover body 12 There was also the problem that parts could not withstand the suction force and dented toward the ventilation fan, resulting in contact with rotating blades and damage.

Problems to be solved by the invention Therefore, the purpose of this invention is to solve all the above-mentioned drawbacks, to make the product foldable, and therefore to be excellent in packaging efficiency and space efficiency for display, etc., and to be able to be used in various formats. It is an object of the present invention to provide a filter cover that can be used in air intake devices such as ventilation fans and range hoods, and can withstand the suction force of the air intake devices.

Means for solving the structural problems of the invention In summary, this invention is a filter cover attached to the intake side of an intake device such as a ventilation fan or a range hood, which is made of a bendable plate-like material. The cover body has a fold line formed almost in the center and has a ventilation opening, a filter member attached to the cover body so as to cover the ventilation opening of the cover body, and the cover body is an air intake device. When the cover body of the intake device is attached to the cover body, the cover body is formed between the surface on which the cover body of the intake device is attached and the cover body so that the folded shape with the raised center part with the crease line part as the ridge line can be maintained when the cover body is attached to the body. The closing piece is provided separately from the cover body or partially continuous with the cover body, and is closed when the cover body is attached to the intake device. This is a filter cover that is attached in such a way that the pieces are glued to the cover body to maintain the folded state of the cover body.

DESCRIPTION OF EMBODIMENTS FIG. 1 is a perspective view showing a filter cover for a ventilation fan as an embodiment of this invention. The filter cover 31 of this embodiment includes a cover body 32 and a filter member 34 provided so as to cover the ventilation opening 33 of the cover body 32. The cover body 32 has a fold line 35 as shown in the figure.
Because it can be folded and bent, it can be made of a relatively thin plate-like member, such as aluminum foil, or a material made by laminating aluminum foil with noncombustible material, flame retardant material, or cardboard. be.

As is clear from FIG. 1, the cover body 32
is bent along the crease line 35, resulting in a swollen shape at the center. Therefore, as is clear from FIG. 2, which shows a sectional view of the mounting state, the motor 36 can be mounted even on a ventilation line 37 having a protruding shape.

Returning to FIG. 1, the cover body 32 has a fold line 35.
Since the portion is raised, a space is created at both ends of the fold line 35, but in this embodiment, a closing piece 38 is provided to close this space. At the same time, the closing piece 38 also serves to maintain the raised shape of the fold line 35 portion of the cover body 32. In other words, even if the suction force of the ventilation fan is quite strong, the closing piece 38 maintains the raised shape of the cover body 32, so that the central part of the cover body 32 is not damaged by being sucked into the ventilation fan. Accidents like this cannot occur.

In FIG. 1, 39a to 39d each indicate a flange piece, which is provided to be attached to a ventilation fan and to be adapted to various sizes of ventilation fans. As shown in the side view in Fig. 3, these flange pieces 39a...39d may be bent in the direction of the arrow x if the ventilation fan to be installed is small, or the part on the intake side of the ventilation fan to be installed is large. In some cases, it can be used as is.

Returning to FIG. 1, through holes 41a and 41b are formed above and below the cover body 32, respectively, and attachment strings 42a and 42b are provided in each of the through holes 41a and 41b.

FIG. 1 shows the shape of the cover filter 31 when it is installed, and FIG. 4 shows a developed view before it is installed. As is clear from FIG. 4, in this embodiment, the cover body 32 and the closing pieces 38, 3
8 are integrally formed of the same material,
By folding along the fold lines 43, 43,
and bending the adhesive margins 44, 44 provided on the closing pieces 38, 38 along the fold lines 45, 45,
By adhering the adhesive margins 44, 44 to the cover body 32, the cover body 3 is fixed as shown in FIG.
It is possible to reliably close the spaces on both sides caused by the bulge in the center of 2.

However, the closing pieces 38, 38 do not need to be formed integrally as shown in the figure, and may be formed separately from the cover body 32, and may be made of metal, plastic, etc. It is also possible to create triangular flat plates and join them.

In the case of the integral cover body 32 made of the same material as shown in FIG. 4, it can be easily folded as shown in the perspective view in FIG. 5, which improves packaging efficiency and display. It is possible to dramatically improve space efficiency. In addition, the part indicated by the one-dot chain line A in FIG. 5 shows the closing piece 38 in FIG. By folding it along the dashed line B, it can be stored as shown in FIG.

In addition, when attaching the ventilation fan filter cover 31 of the embodiment shown in FIG. 1 to the ventilation fan,
As shown in FIG. 2, there are hooks 51a, 5 on the wall.
1b, and a string 42 is attached to the hooks 51a, 51b.
This is done by hooking a and 42b. Of course, the attachment of the filter cover 31 is done using such hooks 51a, 51b and strings 42a,
42b, it goes without saying that any known attachment means can be used, such as double-sided adhesive tape, tension springs, and magnets.

Further, as shown in FIG. 2, strings 42a, 42
It is preferable that b has some slack. This is because if the filter cover 31 is temporarily fixed by the strings 42a and 42b, and if the structure is configured so that the secure fixation is achieved by the suction force of the ventilation fan, gusts or strong winds can flow backwards from outside when the ventilation fan is not in use. Even if the filter cover 31 and the ventilation fan
This is because it is possible to prevent No. 1 from falling off. Taking into account the falling off due to the backflow of outside air, it is found that it is more preferable to use a tension spring or elastic string instead of the above-mentioned loose strings 42a, 42b. Note that, for example, adhesive may be applied to both ends of the resin sheet piece, and one end may be fixed to the cover main body 32 where the other end is to be fixed. If at least one of the sheets to be pasted is made long to provide some space, the same effect as described above can be achieved. Further, a similar structure can be obtained by using a double-sided adhesive tape instead of the adhesive, and in this case, it is preferable to peel off the release paper from the end of the part to be fixed immediately before the fixing operation.

In the embodiment shown in FIG. 1, the cover body 32 has a rectangular planar shape, but the cover body 32 may have a circular shape as shown in FIG. In the embodiment shown in FIG.
is bent along a fold line 65 passing through the center of
The center part is raised. At this time, in order to close the space created on both ends of the fold line 65, closing pieces 68 as shown in FIG.
Attached to both sides of 5. The closing piece 68 is attached by gluing the adhesive margins 68a and 68b of the closing piece 68 to the adhesive margin 69 of the cover body 62 (corresponding to the portion outside the broken line C in FIG. 6). . In addition, in order to facilitate adhesion in the adhesion margins 68a and 68b, cuts may be formed as appropriate. Other points are similar to the embodiment shown in FIG. 1, so detailed explanation thereof will be omitted.

In this way, the planar shape of the main body can be variously selected as required, and the shape of the bulge at the center can also be made as appropriate.

The embodiments shown in Figures 1 and 6 are examples of filter covers for ventilation fans, but this invention is not limited to filters and covers for ventilation fans, but can be applied to filters and covers of any intake device such as range hoods.・It should be pointed out that this can be applied to covers.

Effects of the invention As described above, according to this invention, a filter cover is provided on the intake side of an intake device such as a ventilation fan or a range hood, and is made of a bendable plate-like material and is used for ventilation. The cover body includes a cover body having an opening, and a filter member attached to the cover body so as to cover the ventilation opening of the cover body. When the cover is attached to the intake device, it can be bent to maintain the raised shape of the central part with the crease line as a ridge line, and the central part of the cover body has a raised shape. A ventilation fan with a protruding motor part that further includes a closing piece for closing the space created between the cover body and the surface on which the cover body of the intake device is attached when the fan is attached to the intake device. It can also be installed on In addition, with this design, the crease line formed almost in the center of the cover body becomes a ridgeline, and the central part is raised in the shape when attached to the intake device, so it retains its shape against the suction force of the ventilation fan. This feature is particularly excellent, and prevents the central portion of the cover body from bending toward the intake side of the intake device.

Furthermore, since the cover body is configured to be foldable, it is possible to improve packaging efficiency and space efficiency when displaying at a store or the like. Furthermore, since a plate-like member is used, the cost of the mold can be reduced compared to a molded product, so the cost of the filter cover can also be reduced.
