Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a holding frame for a range hood filter.

[0002]

2. Description of the Related Art In recent years, as a filter for a range hood, a disposable filter made of a non-woven fabric made of a flame retardant material has been used. It is very popular because it is convenient because it does not require cleaning even if oil or dust adheres to it due to its use.

[0003]

By the way, as a holding frame which holds the disposable filter and is attached to the range hood, conventionally, a long plate-like member having a predetermined width is assembled in a substantially rectangular shape. It is configured to have a frame body that is configured and a wire member that is formed in a substantially U-shape and whose base end is rotatably supported on one side of the frame body. After placing the filter on the frame, turn the wire forward and tilt it down,
The filter is held by engaging the tip of the wire with a hook provided on the other side of the frame.

However, in such a structure, since the wire is merely pressed down by the wire, if the oil is clogged and clogged, the filter is sucked by the fan and a gap is generated at the boundary between the frame and the filter. There is a case. If it is used as it is, the function of the filter will be impaired, such as oil directly entering the range hood through the gap. Further, since the 180 ° bending process of the plate material is frequently used, there is a risk that the user may be injured during handling at the corner portion, the edge portion and the like.

Further, the above-mentioned disposable type filter is usually retrofitted to a range hood. In this case, since the size of the part to which the filter is attached varies depending on the type of range hood, many types of filters and holding frames are required, but normally, the length that can be connected to one side of the frame of the holding frame is long. The size of the frame body is adjusted by attaching a plate member. However, since there are many types of range hoods,
According to this adjusting method, it is necessary to prepare various long plate materials having different widths in advance, which is disadvantageous in terms of cost, and there is a problem that the attachment of the long plate material is unstable and the long plate material comes off or shifts. .

[0006]

In order to achieve the above object, a holding frame for a range hood filter according to the present invention is a holding frame for a range hood filter that holds a filter processed into a substantially rectangular shape and is attached to a range hood. In addition, each side has a predetermined width, and a bent portion is formed along the outer edge of each side so as to have a substantially circular cross section, and the entire shape is formed into a substantially rectangular shape which is almost the same as the shape of the filter. The formed first frame body and each side have substantially the same width as the width of each side of the first frame body, and like the first frame body, the entire shape is formed into a substantially rectangular shape, and the base end is formed. Part 1
When it is closed, the outer edge of at least the side facing the base end engages with the bent portion of the first frame to hold the filter together with the first frame. And a second frame body provided so as to perform.

In the drawing, the engaging piece 34a is formed in one place at a substantially central portion of the side 34 with a predetermined width (see FIGS. 1 and 3), but it goes without saying that it may be formed in a plurality of places. is there. When the engaging piece 34a is provided only at one place substantially at the center of the side 34, when the second frame 3 is overlapped with the first frame 2, the vicinity of both ends of the side 34 is obtained. And the first
A gap is likely to be formed between the frame body 2 and one side 24 near both ends thereof. Therefore, in this case, a relatively shallow substantially U-shape which is engaged near both ends of one side 34 of the second frame body 3 only when the second frame body 3 is superposed on the first frame body 2. It is preferable to provide an auxiliary engaging piece (not shown).

Further, when the second frame body 2 is superposed on the first frame body 3 on the outer edge of the side 32 facing the one side 34 of the second frame body 3, Engagement protrusions 32a that are slightly bent are provided so as to engage with the bent portions 22a formed on the opposite sides 22.

Further, the second frame body 3 includes the first frame body 2
Similarly to the above, between the pair of opposing two sides (in the example shown in the drawing, the sides denoted by reference numerals 32 and 34), the wire members 35 and 36 as the filter pressing member made of a thin metal wire have a predetermined interval. Two of them are laid across.

The adjuster 4 fits the size of the ventilation opening of the range hood to which the holding frame 1 is attached,
It is connected to the first frame 2 or the second frame 3 and is arranged to adjust the dimensions of the holding frame 1. Adjuster 4
The shape and the like are not limited as long as they have such a function. However, in the embodiment shown in the drawings, the plate-shaped body 41 is a substantially rectangular shape and is projected on both sides. The projecting pieces cannot be inserted into the bent portions 22a and 24a formed on the pair of two sides (the sides labeled with reference numerals 22 and 24 in the example shown in the drawing) of the first frame body 2 which face each other. Connection part 4 bent inward toward the inside to have a substantially circular cross section
A plate-like body 41 having 1a and 41b, and respective connecting portions 41a,
41b is inserted and fixed, and a pair of two sides of the first frame body 2 facing each other (in the example shown in the drawing, reference numeral 22,
Bent portions 22a, 24a formed on the side marked with 24)
A connecting rod 42 made of a metal wire having a diameter capable of being inserted therein,
And 43 (see FIGS. 1 and 4).

The connecting rods 42 and 43 are connected to the connecting portion 41a,
41b has a length such that its tip projects from one end 41d of the flat surface 41c of the plate-shaped body 41 when fixed to 41b, and as shown in FIG. It is provided so that a slight gap 41e is formed. By having this gap 41e, the connecting rods 42, 43
Is inserted through the openings 22d and 24d formed at one end of the bent portions 22a and 24a of the first frame body 2, the flat surface 41c is located on the back surface side of the first frame body 2. Therefore, the connecting portions 41a and 41b are connected to the openings 22d and 24, respectively.
It can be inserted until it abuts d.

Here, in FIG. 1 and FIG. 4, reference numeral 44
Is a pipe member for position adjustment having an inner diameter that allows the connecting rods 42 and 43 to be inserted, and an appropriate number of connecting rods 4 can be selected according to the size of the ventilation port of the range hood to be attached.
The length of insertion of the connecting rods 42 and 43 into the bent portions 22a and 24a is adjusted by externally inserting the connecting rods 42 and 43.

According to the above-mentioned structure, when the filter made by processing the non-woven fabric into a substantially rectangular shape is attached, first, as shown in FIG. 1, the second frame 3 is placed above the first frame 2. Rotate to and release. Next, the filter is placed on the upper surface of the first frame body 2. After that, the second frame 3
Is rotated downward to engage the engaging protrusion 32a provided on the outer edge of the side 32 of the second frame 3 with the bent portion 24a formed on the side 24 of the first frame 2. Then, it is attached to a predetermined position of the range hood to be attached. Since the filter is sandwiched between the two frames 2 and 3, it is securely held.

When the size of the ventilation opening of the range hood is larger than the size of the first frame body 2, the connecting rods 42, 43.
The two bent portions 22a, 2 of the first frame body 2 facing each other.
Insert the adjuster 4 by inserting it through 4a. As a result, it is possible to attach it to a range hood whose size does not match the size of the first frame 2. Also, when installed, the first frame 2
A part of the ventilation opening of the range hood that is not covered with is covered by the plate-like body 41 of the adjuster 4. Therefore, oil or the like does not directly enter the range hood from a part of the ventilation port which is not covered with the first frame 2. Depending on the size of the ventilation opening of the range hood, an appropriate number of position adjusting pipe members 44 are externally inserted into the connecting rods 42, 43 to adjust the insertion amount of the connecting rods 42, 43 into the bent portions 22a, 24a. What can be done is as described above.

The holding frame of the range hood filter of the present invention is not limited to the above-described embodiment. In the above-described embodiment, the line members 25, 26, 35, 36 for pressing the filter are arranged so as to extend between the pair of sides 22, 24 or 32, 34 facing each other in each of the frames 2, 3. But is not limited to this,
For example, it may be provided between the sides of another set or both sides. Furthermore, it may be provided along a diagonal line of each of the frames 2 and 3. Further, the number to be arranged is not limited. Further, instead of the line member, a long plate material having a predetermined width may be used, and further, it may be formed integrally with the frame bodies 2 and 3 by punching with a press instead of providing it separately. .

[0021]

Since the holding frame of the range hood filter of the present invention has a structure in which the filter is sandwiched between two frames, the filter can be securely held and a gap is created when the filter is sucked by the fan. There is nothing to do.

Further, according to the adjuster of the present invention, since the adjuster has the pipe material for position adjustment, one type of adjuster can cope with other types of range hoods as compared with the conventional one.
