Description

[Detailed description of the invention] (Industrial application field) This invention relates to a simple oil strainer for household use and commercial use such as restaurants, which drains the oil used for tempura and frying.

(Prior Art) Such an oil strainer is known from Japanese Utility Model Publication No. 16367/1983. An oil strainer container (upper container) is fitted and supported at the upper end of an oil receiving container (lower container) that receives filtered oil, and a donut-shaped filter is placed on the bottom of the oil strainer container (upper container). The oil injected into the oil strainer container is filtered by passing it through the overbody in a radial direction from the outer circumference to the inner circumference, and the filtered oil is passed through the inner circumferential hole of the overbody and into the oil strainer container. Drop into the oil strainer container through the opening at the bottom.

In the above conventional example, in order to prevent the oil poured into the oil strainer container from flowing down into the oil receiving container without passing through the inner peripheral hole opened on the upper surface of the overbody, the upper surface of the overbody is almost the same. A lid body with a diameter of 1.5 mm is placed on the lid body, and a support shaft that hangs down from the center of the lower surface of the lid body is inserted into the inner circumferential hole of the over body to prevent the lid body from moving on the upper surface of the over body.

(Problem that the invention aims to solve) However, when dots of oil are injected around the excess body in the oil strainer container, the excess body tries to float up and falls over in the vessel while lifting the lid, and comes out from the opening at the bottom of the container. Unfiltered oil may flow into the oil container. Therefore, to avoid this, it is necessary to pour oil gently onto the lid, which takes time. Furthermore, the oil to be filtered contains fried dregs of various sizes, and these cannot pass radially inward through the over-body, so they stick to the outer periphery of the over-body, and the oil sticks to the outer periphery of the over-body. There are problems such as blocking the infiltration and prolonging the time required.

(Means for Solving the Problems) Therefore, the present invention includes an oil receiving container for receiving waste oil, an oil strainer container having an opening at the bottom and supported at the upper end of the oil receiving container, and a center portion of the oil receiving container. The inner circumferential hole is placed on the bottom surface of the oil strainer container by aligning the inner circumferential hole with the opening in the bottom surface of the oil strainer container, and the oil injected into the oil strainer container is directed radially inward from the outer periphery. An oil strainer having an overbody that allows oil to pass through the oil strainer is provided with an inner bottom plate that fits into the inner periphery of the oil strainer container and is dropped into the inner periphery of the oil strainer container, and the inner bottom plate is in contact with the upper surface of the overbody. It is characterized in that a closing surface that closes the upper end of the inner circumferential hole is provided, and holes for oil straining are provided in the outer sphere surrounding the closing surface.

(Function) An oil strainer container is supported at the upper end of the oil container, an overbody is placed on the bottom of the oil strainer container, and the inner peripheral hole of the overbody is aligned with the opening of the bottom surface, and then the oil strainer is placed in the oil strainer container. Drop in the middle bottom board. As a result, the upper surface where the inner peripheral hole of the overbody is opened is closed by the closed surface of the middle sole plate,
preparations are made.

When oil is poured into the oil strainer container, the oil flows into the cylindrical space formed by the outer periphery of the overbody and the inner periphery of the oil strainer container through the holes provided in the outer sphere of the closed surface of the middle bottom plate. At this time, the dross in the oil that cannot pass through the holes is separated onto the outer space of the inner bottom plate, and the oil that has flowed down into the above space passes through the upper body radially inward from the outer periphery to separate fine lees. While doing so, it reaches the inner circumferential hole of the oil filter and drips into the oil receiving container from the opening of the oil strainer container.

(Embodiment) In the embodiment shown in Figs. 1 and 2, the aforementioned oil container is 1, the oil strainer container is 2, its bottom and opening are 3 and 4, the overbody is 5, the middle bottom plate is 6, and its closed surface is and the outer spheres are 7 and 8.

The containers 1, 2 and the inner bottom plate 6 may be made of metal, plastic, etc., but in this case, they are made of a press molder made of stainless steel plates. Further, the overbody 5 may be a donut-shaped paper laminate or a molded body made of pulp fibers or the like.

The oil strainer container 2 has a bottom 2' periphery attached to the oil receiving container 1.
A bottom surface 3 that is received at the upper end and supported on the oil container 1 and has approximately the same diameter as the overbody on which the overbody is placed.
is formed in a raised bottom shape at the center of the bottom 2'.

In this embodiment, the closed surface 7 of the middle sole plate 6 is also raised one step higher to form a raised bottom shape, and the outer sphere 8 around it is raised one step higher.
A small hole with a diameter of about 1 to 5 mm and a slit with a width of about 1 to 5 mm are made in the hole. In addition to opening small holes or slits in the outer sphere, a large fan-shaped window 9 may be opened as shown in FIG. 3, and a net 9' may be stretched over the window 9.

To carry out the filtering, the oil strainer container 2 is supported on the upper end of the oil container 1, the overbody 5 is placed on the bottom surface 3 of the oil strainer container, and the inner peripheral hole 5' of the overbody and the opening 4 in the bottom surface 3 are inserted. Then, the middle bottom plate 6 is fitted onto the inner periphery of the oil strainer container and dropped. When oil is injected into the oil strainer container, the oil flows down through the holes and meshes in the outer zone 8 of the middle bottom plate 6 into the cylindrical space 10 formed by the outer periphery of the overbody and the inner periphery of the oil strainer container. do. In this case, the lees that cannot pass through the pores in the oil remain separated on the outer sphere 8 and do not reach the space 10. space 1
As the oil flowing down into the oil container 5 gradually passes from the outer periphery to the inside, it separates fine dregs and the like, reaches the inner peripheral hole 5', and drips into the oil receiving container 1 from the opening 4 in the bottom surface 3. . If the bottom surface 3 is formed as a raised bottom as in this embodiment, the fine particles in the oil that have flowed down into the space 10 will settle and accumulate around the wall 3' that raises the bottom surface 3. It is possible to prevent clogging caused by adhesion to the outer periphery of the body, thereby shortening the elapsed time and extending the service life of the body.

Even if oil is injected into the oil strainer container, the inner bottom plate 6 fits into the inner periphery of the oil strainer container and is dropped, and the oil flows into the outer sphere 8 around the closed surface of the inner bottom plate. Since the excess oil is pressed onto the bottom surface 3 of the oil strainer container by the middle bottom plate as it attempts to flow down all at once from a certain hole, floating of the oil can be reliably prevented.

The bottom surface 3 of the oil strainer container of the embodiment shown in FIGS. 1 and 2,
The closing surface 7 of the middle sole plate is approximately equal to the outer diameter of the overbody 5, and allows oil to pass through one overbody.
Suitable for home use.

However, as shown in Fig. 4, the diameters of the oil container 1, oil strainer container 2, and inner bottom plate 6 are increased, and the bottom surface 3 of the oil strainer container is provided with a plurality of openings 4, for example, four openings in the center and four around it. The inner circumferential holes are aligned with each opening, and the five over-bodies are placed on the bottom surface 3, and the middle bottom plate 6 is dropped into an oil strainer container, and the closed surface 7 is placed on the top surface of the five over-bodies. It is also possible to close the upper ends of the inner circumferential holes of each overbody by abutting against each other, thereby allowing oil to pass through areas that are used in large quantities for business purposes, such as cafeterias. In FIG. 4, the same components as in the embodiments of FIGS. 1 and 2 are designated by the same reference numerals, and their explanations will be omitted.

In either embodiment, the middle bottom plate 6 is given a certain amount of weight, and when dropped into the oil strainer container, the overbody 5 is compressed to a certain extent against the bottom surface of the container, and the overbody is given the required overload. It is preferable to allow oil to pass through efficiently. In addition, a knob 11 is provided on the top surface of the inner sole plate to be picked with a finger in order to drop the inner sole plate into the oil strainer container or to pull up the dropped inner sole plate and take it out after the oil strainer is finished. In order to prevent dirt from entering the container 2, it is preferable to close the top surface of the oil strainer container with a lid 12.

Furthermore, an upright wall 6' is provided around the outer periphery of the inner bottom plate in order to prevent the lees on the outer sphere 8 of the middle bottom plate pulled up from the oil strainer container from falling outside and contaminating the surrounding area (Fig. 3). ), or the outer sphere may have a boat-shaped cross-section (see FIGS. 1 and 4).

(Effects of the invention) According to the invention, a middle bottom plate having a closed surface in the center that comes into contact with the upper surface of the overbody and an outer sphere with holes around it is fitted to the inner periphery of the oil strainer container. The oil can be quickly poured into the oil strainer container.
In addition to not requiring time and effort for injection, the lees in the oil are separated by the pores in the outer sphere and are not allowed to reach the overbody, reducing the amount of lees that adhere to the overbody and clog the overbody. It is possible to shorten the elapsed time and extend the service life of the overbody.
