Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an improvement of a filter device for attaching a ventilation fan, mainly for the purpose of preventing oil stains on ventilation fans used in households.

[Conventional technology and its problems]

Conventionally, this type of filter device has a variety of structures, but all conventional filter devices include a main body of the filter device or a frame for fixing a replacement filter member in a stretched state to the main body. Since the structure left the surface exposed, oil and dust would adhere to the exposed surface, not only making your hands dirty when replacing filter members, but also cleaning the main body and frame surface every time you replaced the filter. There was the annoyance of having to perform a cleaning action as well. SUMMARY OF THE INVENTION Therefore, an object of the present invention is to solve such problems and provide a filter device for installing a ventilation fan, which allows easy replacement of filter members.

[Means for solving problems]

The filter device for installing a ventilation fan according to the present invention, which achieves the above purpose, has a required number of beam members installed on the front surface, a horizontal cylindrical main body that covers the front of the ventilation fan to be installed, and an outer side of the cylindrical main body. a replacement filter member having a width that allows the entire surface portion to be bent and further to be folded in a required length toward the inner peripheral surface side of the rear opening edge;
temporary fixing means for fixing the outer peripheral edge of the folded replacement filter member on the inner peripheral surface side of the rear opening edge of the cylindrical main body, so that the replacement filter member covers the entire outer surface of the cylindrical main body. It consists of:

[Effect]

In the filter device for installing a ventilation fan according to the present invention, the replacement filter member surrounds the horizontal cylindrical main body that covers the front of the ventilation fan to be installed, and can be folded in a predetermined length into the inner peripheral surface of the rear opening edge. Since it is wide, the entire outside of the cylindrical main body is prevented from becoming dirty.

Since the replacement filter member is fixed to the cylindrical main body portion by a temporary fixing means, the replacement filter member can be easily replaced by removing the temporary fixing means.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a filter device for attaching a ventilation fan according to the present invention will be described in detail based on the drawings.

FIGS. 1 to 4 show an embodiment of the present invention in which a fitting frame 11 is used as a temporary fixing means 10 for a replacement filter member. , 14 indicates a ventilation fan.

The cylindrical main body 12 has a cylindrical shape or a rectangular cylindrical shape depending on the shape of the window hole 15 of the ventilation fan 14, and is formed in a shape and size so that the rear opening edge 17 comes into contact with the front surface of the window frame 16. and its front opening 18
A required number of beam members 19 are installed across the area.

The replacement filter member 13 is made of coarse non-woven flame-retardant fiber or the like that does not impede air permeability, and surrounds the entire outer surface of the cylindrical main body 12 and further extends around the rear opening edge. It has a width that allows it to be folded in a required length on the inner circumferential surface 20 side of 17.

The fitting frame 11 constituting the temporary fixing means 10 of the replacement filter member 13 is connected to the cylindrical main body 12 to be fitted.
It is formed into a round or square shape that matches the shape of the rear opening edge 17, and its outer diameter is slightly smaller than the inner diameter of the opening edge 17. Reinforce with beam members (not shown). Note that if the rear opening edge 17 into which the fitting frame 11 is to be inserted is round, it is also possible to use a notched circular spring material. It is desirable to form a locking portion such as a locking groove or a projection.

Since this embodiment has the above configuration, in order to attach the replacement filter member 13, first place the cylindrical main body 12 upside down in the center of the replacement filter member 13 facing the floor, and then After lifting the outer circumferential edge 21 of the replacement filter member 13 so as to wrap around the outer surface of the cylindrical main body 12 and folding it into the inner circumferential surface 20 of the rear opening edge 17, the fitting frame 11 is fitted inside it. For example, the outer peripheral edge 21 of the folded replacement filter member 13 is connected to the outer peripheral surface of the fitting frame 11 and the inner peripheral surface 20 of the rear opening edge 17.
The replacement filter member 13 is attached so as to surround the entire outer surface of the cylindrical main body 12. Further, the removal work of the dirty replacement filter member 13 can be easily and quickly performed by simply removing the fitting frame 11.

Next, FIG. 5 shows another embodiment in which a planar fastener 22 is used as the temporary fixing means 11 of the replacement filter member 13, and the cylindrical main body 1
2, planar fasteners 22 are attached to the inner peripheral surface 20 of the rear opening edge 17 at arbitrary intervals.

Therefore, the replacement filter member 1 in this embodiment
The installation work in step 3 can be done by simply pressing the outer peripheral edge 21 of the replacement filter member 13, which is folded into the inner peripheral surface 20 side of the rear opening edge 17, against the surface of each sheet fastener 22. It can be easily removed from the sheet fastener by just pulling with a little force.

As the temporary fixing means 10, various methods other than those shown in the above embodiments can be used, such as double-sided tape, clamping clips, or a large number of needle-shaped fixing pieces. Any material may be used as long as the outer peripheral edge 21 of the folded replacement filter member 13 can be temporarily fixed on the inner peripheral surface 20 side of the rear opening edge 17 of the cylindrical main body 12.

FIG. 4 shows the replacement filter member 13 as described above.
This figure shows an example of the attachment means 23 for attaching the proposed device to the ventilation fan 14.
It is composed of a coil spring member 24 and a mounting board part 25 attached to the ventilation fan 14 side, and has a pressure-sensitive adhesive layer 26 on the back surface of the board part 25, and a base end ring 27 of the coil spring member 24 in the center of the surface.
It has a hook 28 for connecting. Further, the tip of the coil spring member 24 is provided with a hook portion 29 for engaging with the cylindrical main body portion 12, and a ring 3 for gripping.
0 is set. . Therefore, the pressure sensitive adhesive layer 26
By attaching the substrate portion 25 to the front or side surface of the window frame portion 16 of the ventilation fan 14 and engaging the hook portion 29 with the cylindrical main body portion 12 with the coil spring member 24 stretched, the cylindrical main body The present device is installed with the rear opening edge 17 of the section 12 in close contact with the front surface of the window frame section 16.

[Effects of the invention] As is clear from the above explanation, in the filter device for installing a ventilation fan according to the invention, only the replacement filter member is exposed on the surface when it is installed on the ventilation fan. Oil and dust do not adhere to the temporary fixing means, and therefore the replacement filter member can be simply replaced with a new one, making it possible to perform replacement work quickly and easily. Because it is inside the cylindrical main body, there is no adhesion of oil, dust, etc., and therefore there is an effect that your hands do not get dirty during replacement work.
