Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a kitchen grease filter suitable mainly for use in commercial kitchens and the like.
[0002]
[Prior art]
Conventionally, as this type of kitchen grease filter, there are, for example, Japanese Utility Model Laid-Open Nos. 63-16818, 63-218227, 5-293318, and 8-187410. . The one disclosed in Japanese Utility Model Laid-Open No. 63-16818 is a filter made by putting a thin and long curled metal into a casing formed of a metal mesh and a metal frame. No. 63-218227 discloses that an ex-band metal is laminated on both sides of a metal fiber non-woven fabric and pressed or roll-bonded as necessary, and the periphery thereof is press-sealed with aluminum fibers and aluminum expanded metal. The filter material, and the one disclosed in JP-A-5-293318 is a plate-like laminate comprising a metal fiber nonwoven fabric layer and one or two layers of an extended metal layer. The metal fiber non-woven fabric layer and the extended metal layer are pressure-bonded over the entire surface or the periphery of the plate-like laminate is sealed, and the surface of the plate-like laminate It is obtained without a kitchen filter material to form a film of fluorine-based or silicone-based resin. Furthermore, what is disclosed in Japanese Patent Application Laid-Open No. 8-187410 is a metal coil wire winding frame made of a required material, having a width of about 0.5 to 0.6 mm and a thickness of about 0.05 to 0.06 mm. A flat metal coil wire filter is formed by wrapping a flat metal coil wire formed by winding a flat metal wire into a coil shape having a curl diameter of about 4 mm and the front and back surfaces of the multilayer flat metal coil wire filter. Is made of a metal made up of a lower frame body, a left frame, and a right frame, with a substantially U-shaped cross-section capable of disassembling and assembling peripheral surfaces of the metal net and the multilayer metal coil wire filter. The left and right frame bodies are surrounded by a stop edge, and a handle is provided in the left and right frame bodies, and a required number of oil discharge holes are provided in bent corners of the lower frame body.
[0003]
[Problems to be solved by the invention]
However, in the above prior art, what is disclosed in Japanese Utility Model Laid-Open No. 63-16818 is simply a thin and long and curled metal housed in a casing formed of a metal mesh and a metal frame. As a result, the stability of the metal curl housed in the housing is poor, so the oil adsorbing power is unstable, the mechanical strength is weak, and the heat / cold resistance and durability are poor. In addition, all of those disclosed in JP-A-63-218227 and JP-A-5-293318 are formed by pressing a metal fiber nonwoven fabric layer and an expanded metal layer over the entire surface. Since it consists of a laminated body, there was a problem that the oil capturing space in the metal fiber nonwoven fabric layer is quantitatively reduced, and therefore the oil adsorption efficiency is lowered. Furthermore, what is disclosed in Japanese Patent Application Laid-Open No. 8-187410 is the oil trapping in the filter as compared with the conventional laminated plate formed by pressing the entire surface of the metal fiber nonwoven fabric layer and the expanded metal layer. The space for use is extremely large in quantity and can sufficiently capture oil, and the multi-layered flat metal coil wire is wound around the metal coil wire winding frame so that the coil-shaped portion is Since they are entangled with each other, there is no movement, they are stable, they have good oil absorption, they have high mechanical strength, they are not only excellent in heat / cold resistance and durability, but also are easy to disassemble and assemble, Although the filter portion is easy to clean and has various advantages such as simple structure and low cost supply, the front and back surfaces of the multilayer flat metal coil wire filter are simply made of gold. Because it is only sandwiched by one net made of metal, it is weak in strength, so the rectangular metal coil wire constituting the multilayered rectangular metal coil wire filter is affected by the impact caused by contact with other objects during use. In addition to the risk of damaging the human body or other objects by protruding from the mesh portion of the metal net, there are problems such as poor appearance.
[0004]
[Means for Solving the Problems]
The present invention aims to solve the above-mentioned problems, and a metal coil wire winding frame made of a required material has a flat metal with a thickness of about 0.5 to 0.6 mm and a thickness of about 0.05 to 0.06 mm. A flat rectangular metal coil wire filter is formed by wrapping a flat rectangular metal coil wire formed in a coil shape with a curl diameter of about 4 mm, and the front and back surfaces of the multilayer rectangular metal coil wire filter are made of metal. A metal stopper comprising an upper frame, a lower frame, and a left frame and a right frame, which are sandwiched between nets and can be disassembled and assembled to the peripheral surfaces of the metal net and the multilayer metal coil wire filter. In the grease filter for kitchens, in which the left and right frames are provided with handles and the required number of oil discharge holes are provided at the bent corners of the lower frame, the metal net is a small mesh metal. Net With eggplant, further the outer surface side of the metal net of the small mesh, a punching metal plate polymerized distribution and set by interposing a rod for restraining the metal net, also on the outer surface side of the metal net of the other small mesh Instead of the punching metal plate, an expanded metal is arranged in a superposed manner.
