Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an improvement of a filter device for installing a ventilation fan, which is mainly used in homes to prevent oil stains on ventilation fans.

[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 surface remained exposed, oil and dust would adhere to the exposed surface, not only making your hands dirty when replacing the replacement filter member, but also causing the main body to touch the frame surface each time it was replaced. It was a hassle to be forced to use the same cleaning action.

SUMMARY OF THE INVENTION An object of the present invention is to solve such problems and provide a replacement filter device for installing a ventilation fan, which allows easy replacement of replacement 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;
A clip that fixes the outer peripheral edge of the folded-in replacement filter member to the inner peripheral surface of the rear opening edge of the cylindrical main body, and a base having a pressure-sensitive adhesive layer on the back surface and a coil spring having a hook portion formed thereon. and a mounting means for fixing the ventilation fan attachment filter device to the ventilation fan by engaging the hook portion with the cylindrical main body portion.

[Effect]

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

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

The filter device for installing a ventilation fan of the present invention is provided with a mounting means having a base portion having a pressure-sensitive adhesive layer on the back surface and a coil spring member having a hook portion. Therefore, the cylindrical main body portion to which the replacement filter member is temporarily attached can be fixedly held on the ventilation fan.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

1 to 4 show the state in which the replacement filter member is fixed to the horizontally oriented cylindrical main body portion 12 using the clip 11, 13 is the replacement filter member, and 14 is the ventilation fan.

The cylindrical main body part 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 part 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 a 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 replacement filter member 13 is attached to the cylindrical main body 12.
The clip 11 fixed to the rear opening edge 17 of the
As shown in detail in FIGS. 5 and 6, there is a gap approximately equal to the thickness of the rear opening edge 17, and the rolled up replacement filter member 13 is held between the rear opening edge 17 of the cylindrical main body 12. I'm starting to do that.

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 spread out on the floor, and then After lifting the outer peripheral 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 peripheral surface 20 of the rear opening edge 17, insert the clip 11 into the rear opening edge 17. When the replacement filter member 13 is pressed and fitted, the outer peripheral edge 21 of the folded-in replacement filter member 13 is temporarily fixed, and the replacement filter member 13 is
is attached so as to surround the entire outer surface of the cylindrical main body portion 12. Further, the removal work of the dirty replacement filter member 13 can be easily and quickly performed by simply removing the clip 11.

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 proximal ring 2 of the coil spring member 24 in the center of the surface.
It has a hook 28 connected to 7. Furthermore, a hook portion 29 and a hand ring 30 are provided at the tip of the coil spring member for engaging with the cylindrical main body portion 12. Therefore, the substrate section 25 is attached to the front or side surface of the window frame section 16 of the ventilation fan 14 using the pressure-sensitive adhesive layer 26, and the hook section 29 is engaged with the cylindrical main body section 12 while the coil spring member 24 is stretched. In this way, the device of the present invention is installed in a state in which the rear opening edge 17 of the cylindrical main body portion 12 is brought into close contact with the front surface of the window frame portion 16.

[Effect of idea]

As is clear from the above description, the filter device for installing a ventilation fan according to the present invention covers the entire outer surface of the cylindrical main body when it is installed on the ventilation fan, so that oil and dust are prevented from forming on the cylindrical main body. There is no adhesion, so you can simply replace the replacement filter member with a new one.
Replacement work can be done quickly and easily.

Since the filter member can be replaced by removing the clip, it is extremely easy to install and remove the filter member.

In addition, since the attachment is performed by an attachment means comprising a base having a pressure-sensitive adhesive layer and a coil spring member on which a hook is formed, the cylindrical main body surrounded by the replacement filter member is in a pressed state. It can be attached to a ventilation fan and can be easily removed.
