Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filter device for mounting a filter member on an exhaust port of a ventilation fan or a range hood (corresponding to an intake port when viewed from a ventilation fan or a range hood body).

[0002]

2. Description of the Related Art Ventilation fans and range hoods absorb water vapor, dust, oily smoke, etc. from the surroundings and are very dirty and difficult to clean. ,
A ventilating fan cover or a range hood cover) has been installed, and the filter device has been used to collect oil smoke, water vapor and the like contained in the inhaled air. In Japanese Unexamined Utility Model Publication No. 56-149837, a door frame is attached to a cover frame attached to a ventilation fan so as to be openable and closable, a sheet fastener is attached to the inside of the door frame, and a filter is attached to the attached sheet fastener. In use, there has been proposed a ventilation fan cover in which a cover frame is attached to a ventilation fan with the door frame closed.

[0003]

However, in the filter device according to the prior art, the frame body is also contaminated, so that it is necessary to clean it appropriately. Further, once the filter member is attached to the frame body, it is attached to the exhaust port. Therefore, there was a problem that the exchange was difficult. In particular, since range hoods vary in size and shape, and there are several hundred types, it has been extremely difficult to manufacture an appropriate filter device for each range hood. The present invention has been made in view of such circumstances,
It is an object of the present invention to provide a filter device which can be mounted regardless of the type and size of a ventilation fan and a range hood, and which can be replaced at a low cost.

[0004]

According to the present invention, there is provided a semiconductor device comprising:
The filter device attached to the exhaust port according to the above is a filter device attached to the exhaust port of a ventilation fan or a range hood, in which the filter member to be attached is not likely to be caught, wherein the filter is made of only a nonwoven fabric having an area covering the exhaust port. A member and a plurality of substrates each having a hook-shaped protrusion that is directly attached to the periphery of the exhaust port in a dispersed manner and that engages with the periphery of the filter member. The hook-shaped protrusion penetrates the filter member. According to a second aspect of the present invention, there is provided a filter device attached to an exhaust port according to the first aspect, wherein the substrate having the hook-shaped projections is formed of a planar fastener.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described with reference to the accompanying drawings to provide an understanding of the present invention. FIG. 1 is a perspective view showing a filter device attached to an exhaust port according to a first embodiment of the present invention, FIG. 2 is a sectional view of a substrate used for the filter device attached to the exhaust port, and FIG. FIG. 4 is a perspective view of a filter device attached to an exhaust port according to a second embodiment, and FIG. 4 is a perspective view of a filter device attached to an exhaust port according to a third embodiment of the present invention.

[0006] FIG. 1 shows a first embodiment mounted on an iron range hood.
1 attached to an exhaust port according to the embodiment of the present invention.
Although 0 is shown, it has a flame-retardant nonwoven fabric 11 constituting a filter member and a plurality of substrates 14 attached around an exhaust port 13 of a range hood 12.

The non-woven fabric 11 is obtained by cutting a roll-wound non-woven fabric material 15 to a predetermined size with scissors 16 or the like.
When the nonwoven fabric 11 covers the exhaust port 13 (corresponding to the intake port when viewed from the range hood, the same applies hereinafter), the nonwoven fabric 11 has a size that completely covers the exhaust port 13.

As shown in FIG. 2, the substrate 14 has a magnet 17 at the center and a hook-shaped projection 18 on the surface side, which is attached around the exhaust port 13 which is the peripheral portion of the nonwoven fabric 11. Have been. Thereby, the periphery of the nonwoven fabric 11 can be hooked on the hook-shaped projection 18 and attached around the exhaust port 13. The nonwoven fabric 11 is attached to the hook-shaped projection 18 in a penetrating state. And the nonwoven fabric 1
Since 1 is not rigidly mounted, its replacement is very easy.

FIG. 3 shows another example of a substrate having hook-shaped projections, in which a planar fastener 19 having a back surface coated with an adhesive or the like is attached to the outer periphery (or the inner periphery) of the exhaust port 13. Although shown, it is also possible to detachably attach the nonwoven fabric 11 using the hook-shaped projections of the planar fastener 19.
In this case, the hook-shaped projection of the planar fastener 19 also penetrates the nonwoven fabric 11.

FIG. 4 shows an embodiment in which a non-woven fabric 21 constituting a filter member is attached to another range hood 20. A planar fastener having hook-shaped projections dispersed around an exhaust port 22 is shown. Is installed. The periphery of the nonwoven fabric 21 is engaged with and fixed to the planar fastener. In this case also, the hook-shaped projections of the planar fastener 19 penetrate the nonwoven fabric 21.

[0011]

According to the first and second aspects of the present invention, the filter device attached to the exhaust port is apparent from the above description.
Since the filter member such as a nonwoven fabric can be easily attached around the exhaust port, the replacement is extremely easy.
Further, it can be easily adapted to all shapes of the ventilation fan or the range hood, and furthermore, it is only economical to replace the filter member, which is very economical.
