Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a filter used in an oil purifier for purifying frying oil used for tempura and fried dishes.

[Conventional technology]

Various types of oil purifiers are available that remove the color of oil and the smell of fried food by filtering the cooking oil that has become dirty from deep-frying dishes such as tempura. In recent years, the mainstream has become a filter that consists of a filtration container that is detachably attached to the permeation part and an oil storage container that receives the filtered oil. The filter used is a container made of metal or made of natural fibers such as pulp or synthetic fibers filled with activated carbon to remove color and odor components of the oil.

[Problem to be solved by the invention]

Here, when the container is formed of a molded product of fibrous material, it can be provided at low cost, but there are the following problems. That is, this type of filter is fitted into the filter mounting opening of the filtration container, and the flange formed at the upper edge of the filter container is locked to the opening edge of the filter mounting opening, so that the filter can be removed from the filtration container. However, if the container is made of fiber material and the weight of the oil is added to the filter by putting oil into the filter container for oil purification, the flange part will absorb this weight. There is a risk that the filter may become bent and fall into the oil storage container. This is especially true since the flange becomes soft when soaked in oil. In addition, in cases where the oil can be poured out from the spout by tilting the oil storage container while the filtration container and filter are still set in the oil storage container, the filter should be designed so that it will slide off from the filtration container when the container is tilted. It may fall out. This is because the oil seeps onto the outer peripheral surface of the filter container and reduces the frictional resistance between the filter and the mounting opening of the filter container. The present invention has been made in view of these points, and its purpose is to provide a filter for an oil purifier that will not fall off or slip off when set in the oil purifier.

[Means to solve the problem]

Therefore, the present invention provides a container made of a fibrous material and equipped with a flange, granular activated carbon filled in the container, and a container that receives the lower surface of the flange of the container and at least the upper outer circumferential surface 3 of the container. It is characterized by consisting of a covering reinforcing frame. [Function] According to the present invention, the reinforcing frame prevents deformation of the flange portion, and also prevents unnecessary deformation and slippage when attached to an oil purifier. [Example] The present invention will be described in detail below based on the illustrated example. This filter 1 includes a cylindrical case 21 with a bottom, and a case 2.
A container 2 consisting of a lid 22 that closes the top opening of the container 1 is filled with granular activated carbon 3, and the container 2 is attached to a reinforcing frame 1.
0, and the above case 21 and M2
2 are both formed by molding of a fibrous material such as natural fiber, a blend of natural fiber and synthetic fiber, or a blend of natural fiber and inorganic fiber. Further, the lid 22 has unevenness 20 formed on its upper surface, and the case 21 has unevenness 20 formed on the upper and lower surfaces of the bottom plate. These irregularities 20 are provided to increase the surface area and make it difficult to get clogged. On the other hand, as is clear from FIG. 3, the reinforcing frame 10 is made of metal and has a bottomed cylindrical shape with a number of holes 11 formed in the bottom plate, and the upper end receives the flange portion 23 of the case 21. It has a stepped portion 12. Further, a plurality of convex portions 13 are formed on the outer peripheral surface at equal intervals in the circumferential direction. In the illustrated example, three convex portions 13 are provided at 120° intervals. Both the case 21 and the lid 22 are assembled as follows. That is, after filling the case 21 with activated carbon 3, the peripheral edge of the lid 22 is overlapped with the flange portion 23 formed integrally at the upper end of the case 21, and a thick paper such as cardboard is further cut into a ring shape on top of the flange portion 23 formed integrally at the upper end of the case 21. The reinforcing materials 26 created by
The upper end edge of 0 is curled inward to wrap the peripheral edges of the flange part 23, the lid 22, and the reinforcing material 26, and the reinforcing material 26, the lid 22, and the flange part 23 are pressed onto the step part 12 by the curling bent part. When the reinforcing frame 10 is made of cardboard, the stepped portion 12, flange portion 23, lid 22, and reinforcing material 26 of the reinforcing frame 10 may be adhered with glue. FIG. 4 shows an oil purifier 4 using the filter 1 formed in this manner. It is composed of a container 40 having a spout 41 and a handle 42, a cylindrical oil purification bot 5 fitted into the upper part of the container 40, and a lid 6 that closes the top opening of the container 40. Filter 1 and auxiliary filter 7 together with oil purification bot 5
loaded inside. The auxiliary filter 7 includes a furnace material 70 made of plain paper or cloth, a ring-shaped metal fitting 71, and a stopper for fixing the peripheral part of the furnace material 70 to the outer periphery of the metal fitting 71 and attaching the furnace material 70 to the lower surface of the metal fitting 71. It is configured as a metal fitting 72. In the figure, 73 is a handle attached to the metal fitting 71. However, in this oil purifier, the filter 1 is fitted from above into the lower opening of the oil purification bot 5 fitted into the container 40, and the auxiliary filter 7 is loaded on top of the filter 1 to purify the oil used for cooking. When poured into the bot 5, fried crumbs are removed by the auxiliary filter 7, and colored components and odors are removed by the activated carbon 3 in the cartridge-type filter 1, and then stored in the container 40. When reusing the drained oil, the container 4o is tilted by the handle 72, and the oil in the container 40 is poured into a pot or the like through the spout 41. The filter 1 fitted into the small-diameter cylindrical opening formed at the lower end of the oil purification bot 5 has the flange portion 23 of the case 21 received by the stepped portion 12 of the reinforcing frame 10, and the reinforcing frame 1o. Since it rests on the opening edge of the oil purifying bot 5, and because the reinforcing frame 10 has a bottom plate, the filter 1 will not fall off even when the weight of oil is applied. In addition, the frictional resistance between the outer peripheral surface of the reinforcing frame 10 and the inner peripheral surface of the opening of the oil purifying bot 5 and the convex portion 13 provided on the reinforcing frame 10 are locked to the opening edge of the oil purifying bot 5 as shown in FIG. Therefore, the filter 1 will not fall off when the oil purifier is tilted. As shown in FIGS. 6 to 9, the reinforcing frame 10 may have a cylindrical shape without a bottom plate.

【Effect of the invention】

As described above, since the present invention includes a reinforcing frame that receives the lower surface of the flange of the container and covers at least the upper outer peripheral surface of the container, the reinforcing frame prevents deformation of the flange portion and also prevents the oil purifier from deforming. This prevents unnecessary deformation and slipping when attached to the oil purifier.This prevents the flange from falling off due to lack of strength, or from falling off when the oil purifier is tilted. It is easy to use and improves usability.
