Traditionally, this occurs during cooking, not only in restaurant kitchens but also in general home kitchens. Range hoods equipped with rotating exhaust fans are widely used to remove oil smoke and odors. It is used.

0003 By the way, this type of range hood has, for example, a rotating exhaust fan on the hood housing. In addition, the intake port facing the fan is installed on the bottom of the housing as a gas vent. The intake port is open toward the engine, and a filter member such as a guard wire mesh is installed in the intake port. , is stretched to cover the opening peripheral wall surrounding the intake port, and is filtered through a filter member such as a wire mesh. It is designed to be exhausted.

0004 However, because range hoods are frequently used, filters such as the wire mesh mentioned above are required. If used only as a filter member, it will be necessary to wash the filter member frequently, and the filter member will need frequent cleaning. It is troublesome to remove the filter member, and if the filter member is not cleaned, it may become a problem. The surface of the filter member, the surrounding wall of the opening, the exhaust fan, etc. are quickly contaminated with oil smoke. If left in this state, the oil that has adhered and solidified will become liquid and fall onto the gas range. There was a problem that caused unsanitary situations such as

[0005] Therefore, the applicant first proposed a filter that solved this problem, as shown in Figure 4. A range filter made of an aluminum sheet 11 with a filter surface 10 formed thereon. A flap 1 in which a permanent magnet piece 13 is attached to an outer peripheral frame 12 in a card filter. Proposal of a disposable filter with a bendable filter (Jitsuhei 2-44819) No.).

[0006]

[Problem that the idea aims to solve]

This proposed filter can be easily attached to and removed from the range hood, making it preferable for disposable use. It is convenient and can be applied to various types of range hoods that are referred to as shallow or deep types in the industry. It has the advantage of being highly efficient and protects wire mesh filter components that require cleaning time. However, in the above proposal, aluminum 11 is used for the outer frame 12, so when used in a shallow range hood, Since oil smoke is not sucked from the outer frame, oil that is sucked and exhausted from the filter surface While the smoke is still attached to the surface of the outer frame 11 of the aluminum sheet, it is exposed at the lower end of the outer frame. It is difficult to wipe off the oil adhering to the outer frame 12, and it is difficult to wipe it off. It is desired to develop a simple disposable filter that is hygienic and requires no maintenance. Ta.

[0007] In addition, although the proposed filter can be manufactured at low cost, the filter surface 10 In order to attach the outer peripheral frame 12 of aluminum sheet around the There is a limit to cost reduction due to the amount of effort required, and housewives often throw it away. There was a limit in terms of manufacturing costs to offer it at such a low price.

[0008]

[Means to solve the problem]

This invention was developed in view of the problems of the conventional and proposed range hood filters mentioned above. It is hygienic, does not generate oil droplets, is simple and inexpensive, and requires no maintenance. The purpose is to provide a disposable range hood filter. It is made of non-woven fabric formed into a dish shape with a concave center and side walls of an appropriate height. This is a range hood filter, the bottom of which has a series of concave and convex bent parts. It is formed with a corrugated bottom surface and has a non-woven fabric extending outward from the upper end of the side wall. A range hood filter characterized by an integrated mounting part. be.

[0009]

[Effect]

With the above configuration, the present invention has a permanent magnet that covers the suction port of the range hood. By attaching it with stones, etc., oil can be removed not only from the bottom made of non-woven fabric but also from the side walls. The smoke will be sucked in evenly, and the oil will be absorbed and retained by the non-woven fabric, making it difficult for oil droplets to form. Both have a corrugated bottom with a series of concave and convex bends, so oil smoke can be prevented. Not only does the adsorption area become wider and the adsorption efficiency is higher, but also the bending part allows the non-woven bottom to be It works to prevent the bottom surface from sagging, so it prevents a lot of oil smoke from being absorbed by the bottom surface. The bottom of the filter will not sag due to the weight of the oil even if the filter is .

0010 In addition, a mounting part with nonwoven fabric extending outward is integrally provided at the upper end of the side wall. Therefore, any oil that has gotten around between the range hood surface and the mounting part should be removed to the mounting part. It can be absorbed to minimize stains on the range hood.

[0011]

【Example】

The embodiment of the present invention will be explained according to the drawings. Figs. 1 and 2 show the range hood of the present invention. This shows an example of filter 1 for use with polyester fibers or polypropylene fibers. A nonwoven fabric 2 with a thickness of approximately 0.5 mm in which fibers are combined into a three-dimensional network structure with an appropriate binding material. Two thin polyester fiber threads with a diameter of 0.1 mm to 0.3 mm are placed on the top surface. A plain-woven net 3 is attached to a ~4mm square mesh, and the center part is attached to a ~4mm square mesh. The side wall is recessed to a depth of 5 cm, and the whole is shaped into a dish shape.

0012 The external dimensions of the filter 1 above are 37 x 42 cm in vertical and horizontal dimensions, respectively. The vertical and horizontal dimensions of the depression in the center are 27 x 32 cm. , a mounting part 4 of approximately 5 cm is integrally provided around the recessed part with an annular protrusion. There is.

[0013] In addition, the bottom surface 5 formed by the depression is lined with curved concave and convex strips 6, 6, 6, etc. along the lateral direction. The bottom surface is shaped like a wave, and the area between the convex top portion 6a and the concave bottom portion 6b inside the bottom surface is The size is 3 to 4 cm and it is bent in a zigzag pattern at an angle of about 60 degrees.

[0014] In other words, when the nonwoven fabric 2 is in a flat state, it becomes heavy due to oil adsorption because the material is flexible. If the oil becomes too thick, the weight of the adsorbed oil will easily cause the oil to sag. The body shape is formed into a dish shape, and the bottom surface 5 is formed with curved concave and convex strips 6, 6, 6... Since it is formed on the arranged corrugated bottom surface, the inclined wall surface 6c of the curved uneven strips 6, 6, 6... It resists dripping and absorbs a lot of oil without causing dripping. The service life of the filter can be extended from the time it is first used until it is disposed of. Ru. In addition, the suction area of the bottom portion 5 is increased by the bent uneven strips 6, 6, 6... Because of this, it has a high adsorption efficiency for oil smoke from range hoods.

[0015] The bottom surface portion 5 and the bent uneven stripes 6, 6, 6... are formed by dissolving the fibers of the nonwoven fabric 2. It is molded in one piece by hot pressing at a temperature that does not cause any damage. Note that the nonwoven fabric 2 is It may be softened by heating with a mold or the like, and then cold-pressed and molded. Note that the shape of the bottom portion 5 is as follows. , the shape is not limited to a rectangle, but may be an ellipse, and the bent shape of the bottom portion 5 may be a chevron shape. However, the present invention is not limited to this, and may be repeated U-shaped curve molding.

[0016] The polyester fiber thread net 3 attached to the nonwoven fabric 2 has a tear strength of the nonwoven fabric. In addition to reinforcing it, it also prevents it from sagging when attached to the range hood. If the tensile strength of the net 3 is increased and the tensile strength of the weft is increased, the above-mentioned wave A thread with strong tensile strength is arranged along the direction of the convex top part 6a on the bottom of the mold, creating a wavy bottom. It is possible to further increase the effectiveness against sagging of the part.

[0017] The range hood filter 1 of the present invention is suitable for a shallow type range hood as shown in FIG. 3, for example. The intake port of the Jihood 7 is arranged so as to be covered by the corrugated bottom part 5 which is recessed in the shape of a dish. Attach the mounting part 4 extending from the side wall of the cooking part to the housing of the range hood 7 using a permanent magnet or the like 8. It is removably fixed to the underside of the plug. Note that the permanent magnet 8 is integrated with the mounting portion 4 in advance. You can also fix the permanent magnet 8 and prepare the permanent magnet 8 separately. The mounting portion 4 may be fixed by sandwiching it between the lower surface of the housing of the card and the lower surface of the housing of the card. good.

[0018] At this time, since the attachment part 4 made of the nonwoven fabric 2 is provided integrally, the range The oil that has leaked between the housing surface of the board 7 and the mounting portion 4 is removed from the mounting portion 4. It is possible to minimize stains on the range hood 7 by adsorbing it to the microwave oven. Note that when replacing the range hood filter 1, the permanent magnet 8 is Remove it from the range hood, discard filter 1, and install a new range hood filter. Attach.

[Effect of the idea]

As mentioned above, the range hood filter of the present invention has a recess in the center and can be used as needed. It is made of non-woven fabric formed into a dish shape with side walls of the same height, and the bottom surface is uneven. It is formed with a wavy bottom surface with continuous bends, and a non-woven fabric is attached to the upper end of the side wall. The mounting part that extends outward is integrated, so it can be easily attached to the suction port of the range hood. By attaching it with a permanent magnet etc. so that it covers the Of course, the oil smoke will be sucked in evenly from the side wall, and the oil will be absorbed and retained by the nonwoven fabric. Because it is held in place, oil droplets are less likely to form compared to a combination of aluminum outer frame materials, and the frame is Perform maintenance such as wiping off oil droplets around the filter during the usage period before discarding the filter. There is no need for any

[0020] In addition, the bottom surface is formed with a corrugated bottom surface with a series of convex and convex bent sections, so it is easy to prevent oil leakage. Not only does the smoke adsorption area become wider and the adsorption efficiency is higher, but the bent part is the non-woven fabric on the bottom. Because it has the effect of preventing the oil from dripping, even if oil smoke is adsorbed to the bottom part, the oil will not sag. The bottom of the filter will not sag due to the weight of the filter.

[0021] In addition, a mounting part with nonwoven fabric extending outward is integrally provided at the upper end of the side wall. Therefore, any oil that has gotten around between the range hood surface and the mounting part should be removed to the mounting part. It can be absorbed to minimize stains on the range hood.

[0022] Moreover, since the entire body is made of non-woven fabric, it can be used with aluminum outer frame material. Industrial production by molding non-woven fabrics provides a combination of products without the hassle of manufacturing. It is something that can be done.

[0023] Furthermore, a net made of polyester fiber thread is attached to one or both sides of the nonwoven fabric. If the shape is shaped with It has the advantage that it does not sag even if it is lowered.
