Description

  The present invention relates to an oil collecting filter (hereinafter also simply referred to as a filter) used by being attached to a range hood or the like.

  The intake port of the range hood is made of a metal called a grease filter that captures the smoke exhaust fan so that it does not get dirty directly by oil smoke or dust generated during cooking (hereinafter referred to as oil smoke). The filter is attached. However, since this grease filter is cumbersome to clean, a disposable filter made of a material such as a non-woven fabric is further attached to the outside in order to reduce labor.

  As a method of attaching such disposable filters to grease filters and range hoods, commercially available filters are a type in which the filter is attached to the surface of the grease filter with a magnet, and the filter upper and lower parts are wound around the grease filter and then fitted into the groove of the range hood. There is a fixed type. However, mounting with a magnet may cause the filter to drop during use, etc.Wrapping around the grease filter tends to cause wrinkles and slack during mounting, which not only detracts from the beauty of the kitchen but also reduces the oil collecting performance. Connected.

  As a technique for simplifying attachment / detachment to / from the grease filter, a technique described in Patent Document 1 has been proposed. In this technique, a metal stay is provided at the upper end of the filter, the metal stay is wound around the upper end of the grease filter and the upper end of the filter is fixed, and the lower part of the filter is a metal fixing jig. It is fixed with and simplified installation and removal.

  Although the above-mentioned filter simplifies installation, oil and dust adhere to the fixing jig and become dirty, so it is necessary to touch the dirty fixing jig every time the filter is removed. Therefore, the metal stay portion must be removed from the dirty filter and disposed of separately, which is troublesome to handle.

  Accordingly, an object of the present invention is to provide an oil collecting filter that can be easily attached and detached and can be easily disposed of.

  This invention achieves the said objective by providing the filter for oil collection provided with a collection part and the mounting part made from resin which has shape retainability.

  The oil collecting filter of the present invention can be easily attached and detached, and can be easily disposed of.

The present invention will be described below based on preferred embodiments with reference to the drawings.
FIG. 1 shows an embodiment of the filter of the present invention. The filter 1 shown in FIG. 1 has a rectangular sheet-like outer shape, and includes a collection portion 2 and a resin mounting portion 3 having shape retention. The filter 1 includes mounting parts 3 at both upper and lower ends of the collecting part 2.

  As the collection part base sheet (hereinafter, also simply referred to as a base sheet) 20 of the collection part 2, the same sheet as the fiber material sheet conventionally used in this type of filter can be used. . From the viewpoint of being used by being attached to a range hood, the base sheet 20 is preferably flameproof, non-flammable fibers such as glass fiber and carbon fiber, polyvinyl chloride, polyvinylidene chloride, polyclar, flame retardant polyester, It is preferably composed of flame retardant fibers such as flame retardant acrylic and flame retardant rayon, or incombustible fibers or (and) flame retardant fibers are mixed. In addition, the flame-retardant fiber said here shows the fiber whose LOI value is 26 or more. In addition, when the base sheet 20 is not composed of non-flammable or flame retardant fibers, or is configured to have insufficient flame resistance, a halogen-based or phosphorus-based flame retardant is fixed in a post-processing step. It is preferable that flameproofing is imparted by forming a film on the fiber surface using a resin containing a flame retardant as a binder.

  The manufacturing method of the base material sheet 20 is not particularly specified, and after the above-described various fibers are opened by the card method to form a fiber web, the sheet is subjected to an entanglement treatment and the fibers are entangled with each other. Can be used. It is also possible to form a sheet by a method in which hot air is blown onto the fiber web in a penetrating manner to melt the heat bondable fibers and the intersections of the fibers are fused. Or what made the sheet | seat by the method of giving a binder to a fiber web and adhere | attaching the intersection of fibers can also be used. You may combine the sheet | seat of a different manufacturing method for the purpose of improving the balance of air permeability and trapping properties, such as oil smoke, and the intensity | strength of a sheet | seat, and you may use combining different materials, such as a net-like sheet | seat.

The substrate sheet 20 has a fiber fineness of about 1.5 to 30 dtex, a basis weight of 15 to 400 g / m ² , particularly 40 to 300 g / m ² , and a thickness under a load of 0.3 kPa. Is 0.8 to 20 mm, particularly 1.2 mm to 10 mm, from the viewpoint of the balance between air permeability and trapping properties such as oily smoke, and cost.

  The mounting portion 3 is a strip-like shape having a shape retaining property on an extension portion of the base sheet 20 or a mounting portion base sheet (hereinafter also simply referred to as a base sheet) 30 made of a material different from that of the base sheet 20. Resin-shaped shape retaining materials 31 to 33 are joined and provided. Here, the base material sheet 20 of the collection part 2 and the base material sheet 30 of the mounting part 3 are joined by a heat sealing method, and the shape-retaining materials 31 to 33 are made by stacking two base material sheets 30 and heat sealing. Although it is fixed by being stored in the pocket, an adhesive or hot melt can be used as a joining and fixing method, and there is no particular limitation.

  The material of the base material sheet 30 is a core-sheath type having polyethylene, polypropylene, low-melting polyester fibers, etc. as sheath components from the viewpoints of disposability, adhesiveness to the collecting part 2 and shape-retaining materials 31 to 33, and fixability. The binder fiber is preferably used as a constituent fiber. Moreover, it is preferable that the base material sheet 30 is also flameproof, and as a method of imparting flameproofness, a flame-retardant fiber is mixed in the same manner as the base material sheet 20, and a halogen-based or phosphorus-based material is used in a post-processing step. It is preferable that flame retardancy is imparted by fixing a flame retardant or forming a film on the fiber surface using a resin containing the flame retardant as a binder.

The substrate sheet 30 has a fiber fineness of about 1.5 to 30 dtex, a basis weight of 15 to 200 g / m ² , particularly 40 to 100 g / m ² , and a thickness under a load of 0.3 kPa. Is preferably 0.5 to 2 mm, particularly 0.5 to 1.5 mm from the viewpoint of mounting on a grease filter and setting on a range hood. The filter is set by winding the mounting part 3 around the grease filter and fitting it into the groove of the range hood. However, if the basis weight is high and the thickness is too thick, it will be difficult to wind the grease filter. It becomes difficult to fit into the groove of the range hood.

  Examples of the shape-retaining materials 31 to 33 include resin sheets or the like in which a polyolefin-based resin such as polyethylene is strongly stretched in a uniaxial direction to impart shape-retaining properties. While the shape retaining material can be easily folded by hand, the folded shape is maintained, and the oil collecting filter can be easily attached to the grease filter and set on the range hood. The shape holding force of the shape holding material is preferably 0.10 N or more, particularly preferably 0.15 N or more.

  As shown in FIG. 4, the shape retention force of the shape retention material is the push-pull gauge whose tip is a gable type, after the shape retention material is bent at 90 ° and then returned to the opposite side of the folding direction. (AIKOH 9500SERIES) is used for measurement (measured from a predetermined position), and the maximum value at this time is defined as the shape retention force.

  Further, the width of the shape-retaining material is preferably 40 mm or less, particularly preferably 20 mm or less in that it can be easily bent with a hand or a finger. The thickness of the shape-retaining material (thickness under 0.3 kPa load) is 1.5 mm or less, especially 0.6 mm or less, so that it can be easily wound around the grease filter. It is preferable from the point of setting. There are no particular restrictions on the number of shape-retaining materials, either one or more.

  The filter 1 is provided with a slit-like opening 4 in the mounting portion 3 so that a grease filter knob can be inserted. In the present embodiment, two openings 4 are provided so that selection can be made according to the size of the grease filter to be attached.

  The filter 1 is provided with a cutting guide wire 5 so that it can be selected and used in accordance with the sizes of the two types of grease filters, and the shape holding member 33 and the opening 4 are arranged in accordance with this.

  If necessary, the filter 1 is cut along the cutting guide line 5 and matched with the size of the grease filter to be attached, and then the mounting portion 3 is bent along the upper and lower ends of the grease filter 10 as shown in FIG. Further, a grease filter knob 100 is inserted into the opening 4 and attached, and in this state, the grease filter is attached to the range hood.

  After use, it is removed from the grease filter, and, as shown in FIG.

  As described above, the filter according to the present embodiment can be attached and detached without any trouble, and can be used by cutting according to the size of the grease filter, as well as being easy to dispose of without being separated. Moreover, since the opening part for inserting the knob | pick part is provided, it is excellent also in the fitting property to the grease filter surface.

  The present invention is not limited to the above-described embodiment, and can be changed as appropriate without departing from the spirit of the present invention.

  In the filter of the above embodiment, the shape retaining material, the opening, and the cutting guide wire are arranged so that they can be used according to the sizes of the two types of grease filters, but these are further increased according to three or more sizes. They can also be arranged, and when one type of size is targeted, these can be omitted.
