Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a disposable range hood filter that is used by being attached to a range hood that is disposed above a gas cooking range to exhaust smoke. It is something.

[Conventional technology]

As is well known, a range hood has a structure in which an intake port facing the exhaust fan is opened on the bottom surface of a housing housing a built-in exhaust fan, and this intake port is covered with a guard wire mesh, a special filter, a grease filter, etc. The gas stove is placed on top of the gas range with the intake port facing towards the gas range, and exhausts oil smoke etc. emitted from the food being cooked through a member such as a wire mesh. Because the range hood is used frequently, parts such as the wire mesh of the range hood, the walls around the intake port, and even the exhaust fan, etc., will be contaminated by oil smoke at an early stage, and if left unattended, the oil will adhere and solidify. This may lead to unfavorable sanitary conditions such as dripping onto the gas range.

In order to eliminate such inconveniences and keep range hoods sanitary, replaceable and disposable range hood filters have recently been proposed.

[Problem that the invention attempts to solve]

By the way, there are a wide variety of types of range hoods, including those that are classified in the industry into types commonly referred to as shallow types and deep types. Among them, for example, the width dimension of deep hoods for general household use is a standard size and is almost constant regardless of the type, but the depth dimension varies depending on the type.

However, in the case of conventional filters, for example,
Flaps are extended on the four sides of the frame, and each flap is bent and attached to the wall around the hood's intake port, so not only can it be used with range hoods of various sizes, but it can also be used with different sizes of range hoods. It is nearly impossible to manufacture a filter that is compatible with this type of filter, and there are problems in that it is relatively expensive and the replacement work is complicated.

The object of the present invention is to provide a disposable range hood filter that can be easily attached to and removed from the range hood and can be applied to several types of range hoods.

[Means for solving problems]

In order to achieve such an object, the range hood filter of the present invention has a filter member 2 mounted on a rectangular frame 1 made of an aluminum sheet to form a filter surface, as shown in the drawings corresponding to the embodiments. forming the opposite short side portion 1 of the frame portion 1;
Permanent magnet pieces 4, 4 are provided on b, 1b so as to be bendable to the front and back sides, and a tightening portion 6 is formed over almost the entire outer periphery of the frame portion 1.

Preferably, the permanent magnet pieces 4, 4 extend from the short sides 1b, 1b of the frame 1 through at least one bendable bending part 8. It is preferable that the folding portions 8, 8 are fixed to the short flaps 3, 3, and in this structure, it is even more convenient if the bent portions 8, 8 are formed into a bellows shape that can be expanded and contracted.

[Effect]

For example, when installing a deep range hood, two filters of the same size with the above features may be installed.
One long side of both filters is aligned with the surrounding wall of the intake port, and the flaps 3, 3 to which the permanent magnet pieces 4, 4 of each filter are fixed are bent in either direction of the front or back of the filter surface. By placing the permanent magnet pieces 4, 4 in contact with the circumferential wall of the range hood intake port 7, the permanent magnet pieces 4, 4 are attracted to the circumferential wall and can be easily attached.

When the size of the intake port 7 is smaller than the sum of the widths of both filters, the adjacent frame portion sides 1a, 1a of both filters are partially overlapped. In this case, since the permanent magnet pieces 4, 4 are not provided on the long sides 1a, 1a, the filter action of the overlapping portion of the two filter surfaces is not inhibited by the flaps 4, 4, and the frame portion is short. The flaps 4, 4 provided on the sides 1, 1b are attached to the short side 1.
Since they are shorter than b and 1b, they do not interfere with each other and do not interfere with the installation and removal of the filter.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail based on the drawings. The range hood filter F according to this embodiment shown in FIGS. 1 to 6 has a filter surface formed by attaching a filter member 2 to a rectangular frame 1 with length and width dimensions of about 57 cm x 23 cm, for example. At the same time, flaps 3, 3 are extended from the opposing short sides 2 of the frame 1, and permanent magnet pieces 4, 4 are fixed to each flap 3, 3, so that the frame 1 and the flaps 3, 3 are fixed to each other. is formed by cutting out a single aluminum sheet, but it may also be divided into two parts and joined together.

The frame part 1 has long sides 1a, 1a, short sides 1b, 1b, which constitute the outer shell, and two reinforcing beams 1c, which span between the opposing long sides 1a, 1a at the middle part in the longitudinal direction. , 1c, and the corners of each long side 1a and short side 1b and the long side 1
The corner portions of the reinforcing beam portion 1c and the corner portion a of the reinforcing bar portion 1c are each formed into a smoothly continuous arc shape.

As shown in FIG. 4, reinforcing strips 5 having a trapezoidal cross section are formed in series on each side of the frame 1, and protrude toward the front side when attached to the range hood R. As a result, the frame part is opposed to the external force applied when handling the filter F and the negative pressure generated by driving the exhaust fan (not shown) of the hood R when the filter F is attached to the range hood R. The purpose is to suppress the deformation of 1. Also, the frame portion 1
Almost the entire periphery of the outer periphery except for the flap attachment portion and the outer periphery of the flaps 3, 3 are reinforced by seaming. As shown in FIG. 5, this tightening portion 6 is preferably formed so as to protrude exclusively toward the front side of the frame portion 1, and is flush with the back side of the frame portion 1.
When the range hood R is attached to the intake port 7, it is preferable that the frame portion 1 immediately come into contact with the intake port 7.

The reinforcing beams 1c, 1c may be arranged parallel to the short sides 1b, 1b as shown in FIG. It may also be formed by sides.

The filter member 2 is made of, for example, a fiber web with a small basis weight, is attached to the back side of the frame portion 1 to cover the space formed within the frame portion 1, and is passed through the filter member 2 by suction from an exhaust fan. It adsorbs and removes oil droplets, etc.

The flaps 3, 3 are each shorter than the short sides 1b, 1b of the frame portion 1, and specifically have a width dimension of about 1/2 to 1/3 of the short side 1b,
Similar to the frame portion 1, the corners are arcuate. The central portion of the flap 3 is curved in the same direction as the reinforcing strip 5, and a permanent magnet piece 4 is placed on the back side of the curved portion.
is fixed. This permanent magnet piece 4 is fixed to a mounting bracket 4a having a U-shaped cross section using adhesive or double-sided adhesive tape, and is further attached by fixing this mounting bracket 4a to the flap 3 with an eyelet 4b or the like. . As shown in FIG. 4, if the attraction surface of the permanent magnet piece 4 is located slightly inside the end of the mounting bracket 4a, the magnetic field of the magnet 4 can be applied to the wall surface of the inlet 7. can be made the strongest.

At least one bendable bending section 8 is formed between each of the flaps 3, 3 and the short sides 1b, 1b. As shown in the cross-sectional view in FIG. The length can be adjusted accordingly, and the bellows can be bent toward the surface of the frame 1 from the fold line of the bellows. Note that, instead of having the above-mentioned bellows-like structure, the bent portions 8, 8 may be formed with a plurality of folded lines in the extending direction of the flaps 3, 3, and may be adapted to fit the dimensions of the intake port 7. flaps 3, 3 along the bend
It may be bent.

When installing the range hood filter F configured in this way to a deep range hood R as shown in FIG. 7, and attach the permanent magnet pieces 4, 4 to the peripheral wall of the inlet 7 by adsorption.
At this time, if the depth of the intake port 7 is less than the sum of the widths of the two filters F, F when they are lined up, as shown by the imaginary line in FIG. It is preferable to overlap F and F at the adjacent long side portions 1a and 1a. in this case,
Since the flap 3 does not exist in the overlapping portion, the filter function of both filters F and F and the intake function of oil smoke and the like caused by the exhaust fan of the range hood R are not impaired. Also, both flaps 3, 3
Since they are formed sufficiently shorter than the short sides 1b, 1b, they do not interfere with each other and can be easily attached. Moreover, by shortening the flaps 3, 3 in this way, a sufficient adsorption effect can be achieved by simply providing one permanent magnet piece 4, 4 on each flap 3.

[Effect of idea]

As explained above, according to the present invention, for example, two
By using two filters, it can be attached to any range hood having various dimensions. That is, by bending the flap of each filter and bringing it into contact with the surrounding wall of the intake port of the range hood, the permanent magnet pieces 4, 4 are attracted to the surrounding wall and can be easily attached, and the dimensions of the intake port are set to the width of both filters. If it is smaller than the sum of , the filter function and the exhaust function of the range hood can be maintained even in the overlapping part of the filter surfaces by partially overlapping the adjacent long sides 1a and 1a of both filters. Since it does not interfere, it can be used with a wide variety of range hoods and can be installed easily and in good condition. Moreover, the frame part 1 has a seaming part 6
Since it is reinforced with , it does not deform due to external force during use or handling, and can be used satisfactorily for a long period of time, resulting in excellent practical effects.

Also, the short sides 1b, 1b of the frame 1 are
If flaps 3, 3 for attaching permanent magnet pieces shorter than b, 1b are provided, the flaps 1b, 3 at the overlapping part
1b do not interfere with each other, and therefore the filter can be attached and removed very easily without any trouble.

Furthermore, the flaps 3, 3 and the short sides 1b, 1 of the frame 1
By forming the bent parts 8, 8 interposed between b into an expandable bellows shape, the length can be flexibly adjusted to correspond to the dimensions of the range hood intake port 7, so that the frame part 1 can be
It can be brought into contact with the intake port 7 soon.
