[Problems to be solved by the device]

 When replacing the filter 7, first remove the filter unit 5 from below the panel 2. Then, the lid 6a of the net frame 6 is opened, the filter 7 inside is taken out, and this filter 7 is replaced with a new filter 7. At this time, the net frame 6 is considerably soiled by the oil and fat components. Therefore, when the filter 7 is taken out, the net frame 6 is washed with a detergent, and a new filter 7 is placed in the net frame 6 after the washing. Store.

As described above, in the conventional case, when the dirty filter 7 is replaced, the filter unit 5 is removed from the panel 2, and then the filter 7 is taken out from the mesh frame 6 of the filter unit 5 to further shape it. However, there is a problem that the troublesome and troublesome work of cleaning the large net frame 6 is required.

The present invention has been made by paying attention to such a point, and an object of the present invention is to install a ventilation fan with a filter that does not require any trouble to replace the filter and can easily and efficiently replace the filter. To provide a device.

[0008]

[Means for Solving the Problems]

 In order to achieve such an object, the present invention forms a ventilation opening in a panel made of a magnetic material, and a ventilation fan main body having a ventilation fan inside the opening, and the outer surface of the panel. And a filter that is detachably provided so as to face the opening, and the filter is formed by pressing aluminum fiber into a felt-like flat plate shape. A crushed thin portion is formed by crushing, and this filter is provided on the outer surface of the panel of the ventilation fan body so as to face the opening, and a plurality of magnet stoppers are evenly arranged on the crushed thin portion, The filter is detachably attached to the panel by the magnetic force of the magnet stopper.

[0009] Preferably, a line-shaped crushed thin portion that is continuous from one end side to the other end side of the filter is formed in a portion of the entire area of the filter, and a tongue for picking is provided on the magnet stopper. Provide a piece.

[0010]

[Operation] When replacing the filter contaminated with oil and fat components with a new filter, first remove the magnet stopper by pulling it away from the panel. This will disconnect the filter from the panel, so remove the filter from the panel. Then replace this dirty filter with a new one. At this time, since each magnet stopper is often soiled with an oil component, it is washed with a detergent or the like. Then attach a new filter to the underside of the panel using the washed magnet stop. This completes the filter replacement work.

At the time of this replacement, the conventional troublesome work of inserting and removing the filter with respect to the mesh frame and the trouble of cleaning the mesh frame are unnecessary, and only the magnet stopper is simply washed. And, unlike the conventional net frame, the magnet stopper is a small member with a simple shape, and therefore these magnet stoppers can be easily and easily cleaned without requiring labor.

[0012]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a perspective view of the ventilation fan device. Reference numeral 11 is a ventilation fan main body, 12 is a panel, 13 is a ventilation opening, and 14 is a ventilation fan. The panel 12 is made of a magnetic material such as a steel plate, and the lower surface of the panel 12 is painted.

A filter 15 is provided on the lower surface of the panel 12 so as to face the opening 13, and the filter 15 can be attached to and detached from the panel 12 via a plurality of magnet stoppers 16 arranged on the periphery of the filter 15. Is attached to.

The filter 15 is formed by laminating aluminum fibers at a predetermined density and pressing the same from above and below to form a felt-like flat plate. The filter 15 is cut into a rectangular shape having a length of 30 cm and a width of 35 cm, for example, so as to fit into a domestic range hood.

Further, as shown in FIG. 2 and FIG. 3, the filter 15 has a crushed thin portion 15a having a width of about 3.0 cm on the four side edges and a portion of the entire area of the filter 15 as shown in FIG. Further, thin line-shaped crushed thin portions 15b having a width of about 2 mm, which are continuous from one side edge to the other side edge thereof, are formed in parallel with each other at intervals of about 1.5 cm. These crushed thin portions 15a and 15b are formed by pressing a predetermined portion of the filter 15 strongly with a roller to crush it.

As shown in FIGS. 4 and 5, the magnet stopper 16 is formed by integrally covering a rectangular magnet piece 17 with a case-shaped cover 18 made of, for example, a steel plate or a steel plate on one side. Combined with. A tongue piece 18a for picking is integrally formed on the edge of the cover 18 on one end side.

The magnet stoppers 16 are evenly arranged on the crushed thin portion 15 a at the peripheral edge of the filter 15, and the magnetic force between the magnet pieces 17 of the magnet stopper 16 and the panel 12 causes the filter 15 to move. It is attached to the panel 12.

In the ventilation fan device having such a configuration, gas such as oil smoke generated during cooking is sucked into the inside of the opening 13 through the filter 15 and discharged to the outside of the room. Then, as the gas such as oil smoke permeates the filter 15, oil and fat components adhere and gradually become dirty.

When the filter 15 is contaminated for a certain amount or more, the filter 15 is replaced with a new one. At the time of this replacement, first, the tongue piece 17a of the magnet stopper 16 is pinched with a hand, and the magnet stopper 16 is pulled down and removed from the panel 12. As a result, the joint between the filter 15 and the panel 12 is released, so the filter 15 is separated from the panel 12. Then, the dirty filter 15 is replaced with a new filter 15. At this time, since the magnet stoppers 16 are often soiled with oil and fat components, they are washed with detergent or the like. Then, a new filter 15 is attached to the lower surface of the panel 12 using the washed magnet stopper 16. This completes the replacement work of the filter 15.

In such replacement, there is no need to insert and remove the filter 15 from and into the mesh frame as in the prior art and to clean the mesh frame. Just do it. Unlike the conventional mesh frame, the magnet stopper 16 is a small member having a simple shape. Therefore, these magnet stoppers 16 can be easily and easily cleaned without requiring labor.

Since the material of the filter 15 is aluminum fiber, the filter 15 is in a relatively strong state with a certain tension, but the entire area of the filter 15 is thin and parallel with a certain distance. The crushed thin wall portion 15b is formed, so that the bulge of the aluminum fiber is suppressed, and the overall stiffness of the filter 15 is further strengthened. Therefore, when the filter 15 is attached to the lower surface of the panel 12, This filter 15 will not be deformed carelessly.

Further, the filter 15 has a crushed thin portion 15a formed on the periphery thereof, and a magnet stopper 16 is disposed on the crushed thin portion 15a. Therefore, each magnet stopper 16 is attached to the panel 12. The magnets 17 of the magnet stoppers 16 arranged close to each other effectively act on the panel 12, so that the filter 15 can be firmly and stably attached to the panel 12.

The present invention can be applied not only to a range hood type ventilation fan device, but also to a wall surface direct attachment type fan device provided on a vertical wall surface of a kitchen.

[0024]

[Effect of device]

 As described above, according to the present invention, there is an advantage that a filter contaminated with a fat and oil component can be easily and efficiently replaced with a new filter without any troublesome work.
