Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a filter device for a range hood, and more specifically relates to a detachable filter for a range hood.

[Prior Art] As a ventilating fan that accompanies a range hood, the type shown in FIG. 1 is generally known, and in FIG. 1, a ventilating fan 2 is often attached directly to a hood 1.

[Problems to be solved by the invention] In the conventional technology described above, the hood and ventilation fan become dirty due to steam and oil smoke generated during boiling, grilling, and stir-frying, and because of the presence of the hood, the interior of the ventilation fan becomes dirty. There is a problem in that it is difficult to clean the ventilation fans.

For this purpose, it is possible to prevent the ventilation fan from getting dirty by installing a filter in front of the ventilation fan that does not impede ventilation efficiency, but there are many types of ventilation fans, and the mounting position and dimensions of ventilation fans that are attached to the hood or the wall of the building are still disputed among manufacturers. There was a problem in that in order to jointly tighten the filters using ventilation fan mounting screws, which were not standardized, it was necessary to prepare a large number of mounting holes and mounting means on the filter side, which was impractical.

Furthermore, as a conventional filter for a ventilation fan other than a range hood, there is a filter described in, for example, Japanese Utility Model Application No. 55-130137.

This conventional technology consists of a frame body with a ventilation passage formed therein;
a blower provided in the ventilation passage; a decorative grille that is removably provided at the opening of the ventilation passage and formed to allow ventilation; a fixing member provided on either the decorative grille or the frame; This ventilation fan is made up of this fixing member and a filter sandwiched between the decorative grille and provided across the ventilation path.

However, this prior art has a problem in that it cannot be applied to the range hood shown in FIG. 1 because of its shape and structure.

Apart from this, there is also one disclosed in Japanese Utility Model Application Publication No. 56-53130.

This prior art is a kitchen ventilation fan in which an oil collection filter having an oil collection filter element and a filter frame is provided on the suction side of the ventilation fan main body such that the oil collection filter element is on the ventilation fan main body side. This ventilation fan is characterized in that a guide portion for receiving oil, etc. is provided on the surface of the filter frame on the anti-oil collecting filter element side.

Furthermore, there is also one shown in Japanese Utility Model Publication No. 51-50676.

In this conventional technology, a magnetic flange is formed on the suction side end of a casing that has an electric fan inside, and the flange part of a dust removal screen with magnets embedded in this flange is attached and detached in multiple stages. It is a ventilation fan.

However, among the conventional techniques mentioned above, Utility Model Application No. 56-53130
The only gist of what is shown in the publication is that the filter frame is provided with a guide section consisting of a groove for collecting oil, etc., and in order to attach the filter frame to the ventilation fan body, it must be held by hooking it onto the filter holder. It is not easy to install or remove, and the filter element is simply applied to the filter frame with a filter holder, so only thick filter elements with considerable rigidity can be used, and space is limited. However, there are many problems such as being economically disadvantageous, inconvenient to use, and bulky during transportation and storage.

Furthermore, the prior art disclosed in Japanese Utility Model Publication No. 51-50676 focuses on attaching a plurality of dust removal nets to the magnetized flange of the casing by sequentially stacking them on top of each other and attaching them to the magnetic flanges using magnets. It is either glued to the flange or integrally formed, so when the dust removal screen gets dirty and you replace it with a new one, you can replace it with the flange that has multiple magnets embedded in it and throw away the dirty one. It is.

Therefore, it is impossible to replace only the filter fabric, and the flanges and multiple expensive magnets must be discarded each time the dust removal screen is replaced, which is a waste of resources and extremely uneconomical. .

The purpose of this invention was to eliminate the above-mentioned problems by providing a magnetic catcher that could be easily attached to and removed from an existing ventilation fan, either directly or using a hood, and by attaching it to the frame member of the filter material. To facilitate the installation and removal of filter materials and to beautifully tension the filter material.

[Means for Solving the Problems] The object of the invention described above is to provide a pair of side frame plates each having a locking edge on each end of a pair of inclined surfaces, and a pair of side frames having a magnetic catcher. a frame member having a substantially rectangular outline made of a plate; a relatively large outer frame having a substantially rectangular outline in contact with the crosspiece and the edge of the side frame plate and the locking edge of the side frame plate, respectively; A filter presser fitting consisting of a crosspiece that follows the pair of sloped surfaces of the frame plate and comes into elastic contact with the locking edge, and a filter holder of a size such that the peripheral portion touches the edge of the frame member and the pair of sloped surfaces. and a flexible non-combustible filter material, and tension is applied to the non-combustible filter material held between the inclined surface of the side frame plate via the outer frame by the locking elasticity against the locking edge of the crosspiece. This is achieved by giving.

[Function] A frame member consisting of a pair of side frame plates having an inclined surface and a locking edge and a pair of side frame plates having a magnetic catcher is provided with a crosspiece and an edge of the side frame plate and the side frame plate. A filter holding fitting has a substantially D-shaped outer frame that contacts the edges of the frame member, and is made of a crosspiece that runs along the slope of the side frame plate. By sandwiching and attaching the filter material of this size, the filter material can be easily attached to and removed from the range hood frame member.

In particular, in this invention, tension is applied to the flexible non-combustible filter material held between the inclined surface of the side frame plate via the outer frame by the locking elasticity against the locking edge of the crosspiece, so that the filter material is Can be set up beautifully.

[Example] Examples will be described with reference to the drawings.

FIG. 2 shows the structure of the frame member for the range hood shown in FIG. Joined into a rectangular frame shape, the side frame plate 13
A magnetic catcher 17 is attached to the inside of the holder with screws 18.

FIG. 3 shows the structure of the filter holding fitting 21, which includes a crosspiece 22 made of a thin metal rod slightly shorter than the length of the side frame plate 16,
A crosspiece 23 made of a metal rod with a small diameter slightly shorter than the length of the side frame plate 13 is attached so that it touches the edge 12 of the side frame plate 13 and the locking edge 15 of the side frame plate 16, respectively. Outer frame 2 formed by bending a metal rod into a substantially D shape
4, and the side frame plate 1 is longer than the side frame plate 13 and both ends thereof are longer than the side frame plate 13.
It is made by welding a crosspiece 25 made of a thin metal rod bent so as to follow the inclined surface 14 of 6.

The filter of this invention uses the frame member and filter holding fitting constructed as described above, and as shown in FIG. A non-combustible filter material 31 having a flexible size corresponding to the peripheral portion is disposed in a part of the filter material 31, and the filter material 31 is pressed onto the filter material 31 with a filter presser fitting 21.

The filter holding fitting 21 described above has its outer frame 24
Tension can be applied to the filter material 31 by being locked on the locking edge 15 on one side of the two sides, and on the other side, a pair of curved portions 26 formed at two locations are locked, and the filter material 31 is locked on the other side. are the other two sides of the outer frame 24 and the crosspiece 2
2, 23, and 25 are arranged so that they do not fall off on one side of the frame member 11 (the one with the larger opening area).

The filter A made in this way is the frame member 1.
Magnetic catcher 17 attached to 1
The filter A is adsorbed and fixed to the metal frame of the ventilation fan shown in FIG.

If the filter material 31 becomes dirty, remove the filter from the ventilation fan, and pull the pair of handles 27 formed on the outer frame 24 of the filter retainer 21 toward you, and the curved portion 26 will be released from the locking edge 15. Therefore, it can be easily removed by holding the handle 27 and pulling it towards the side where the handle is formed, so replace the dirty filter material 31 with a new filter material, and then attach the filter material 31 to the frame member 11 using the filter retainer 21 in the same manner as described above. Install and use.

In this case, the magnetic catcher 17 is connected to the frame member 1.
Although it is attached to the inside of the frame member 1, there is no problem even if it is attached to the outside of the frame member.

[Effects of the invention] Since this invention is configured as described above, it produces the effects described below.

The magnetic catcher makes it easy to attach and detach the filter material to the range hood.
Moreover, tension is applied to the flexible non-combustible filter material 31 which is held between the inclined surfaces 14, 14 of the side frame plates 16 via the outer frame 24 by the locking elasticity of the crosspiece 25 against the locking edge 15. Even if a flexible and thin filter material 31 is used, the filter material 31 can be stretched very flat and beautifully.

Therefore, the filter material does not take up much bulk, making it possible to save space during transportation and storage, and also improve usability for the user.In particular, in this invention, only the filter material 31 can be removed from the frame member 11 of the outer frame 24. Since the frame member 11, the outer frame 24, and the expensive magnetic catcher 17 can be easily removed and replaced with a new one, the frame member 11, the outer frame 24, and the expensive magnetic catcher 17 can be used many times, which has many advantages such as saving resources and being economical. .
