[Background Art 1] Japanese Patent Laid-Open No. 61-259627 discloses an oil purifier in which an oil purifying section is provided in the upper part of the container and an oil storage part is provided in the lower part. This is done by pouring oil into the oil reservoir through an opening at the top of the container, passing through the oil purification section, and then pouring out the oil stored in the oil reservoir by tilting the container. There is.

Here, in the conventional example described above, both the container and the oil purification section have a substantially circular horizontal cross section so that the oil purification section fits completely into the upper part of the container. The flow path between the spout and the opening was secured by inflating part of the container outward. For this reason, the outer surface of the container is uneven, and when oil or dirt gets on it, it is difficult to remove it even after washing, which not only poses a hygiene problem, but also makes it easy for the container to get scratched and wrinkled during processing. Processing is also difficult. Furthermore, the oil purifying section needs to be removable for replacing the overfill material and cleaning the inside of the container, but the oil purifying section fits into the container with almost no gaps. Therefore, it is difficult to remove.

4, and includes an engaging piece 46 that protrudes downward through an opening 51 formed in a bottom plate 50 that closes the lower opening of the knob 44, and anti-slip unevenness that protrudes laterally from windows 54 formed on both sides of the knob 44. A convex portion 47 formed on the surface, a groove 49 that slidably engages with a rail-shaped rib 55 formed on the inner surface of the knob portion 44, and a protrusion 48 extending from the negative side.
A compression coil spring 51 is installed between both lock buttons 45 and 45.

With the protrusion 14 of the ring body 11 engaged with the four parts 43 of the hanging piece 42, if the knob part 44 located on the handle 7 is pushed downward, the engaging piece 46 of each lock button 45 is formed into the rib 74. In order to be locked in the through hole 75 provided in the main body 1, the master 40 is attached to the container 1 in such a manner that it will not come off inadvertently.

To remove the main controller 40, push the protrusions 47 of both lock buttons 45, 45 against the compression coil spring 51 with fingers pinching the knob 44, and press the lock buttons 45, 45, which are moved by the ribs 55 in a gamma direction. What is necessary is to release the locking piece 46 from engagement with the rib 74, and in this state, pull up the side of the knob 44. At this time, the recess 43 formed in the hanging piece 42
The engagement between the protrusion 14 and the protrusion 14 is released naturally.

Note that it is possible to use the same double-ended hook @45.45. Further, the bottom plate 50 is attached to the knob 44 by locking a protrusion 52 protruding from the side edge of the bottom plate 50 to the inner surface of the knob 44. Further, the protruding piece 48 has a ninth portion protruding from the inner surface of the knob portion 44.
The lock button 44 is prevented from twisting and rattling between the rib 53 shown in the figure.

As shown in FIGS. 6 and 7, the oil filling lid 41 is
It is attached to the master 40 by locking one end of a spring 56 made of stainless steel or the like arranged in a recess 55 formed in the recess 55 to the lower surface of one end of the oil filler lid 41, and when the oil filler lid 41 is tilted down, the spout opens. 10 is closed to prevent dirt, dust, insects, etc. from entering, and when raised, the spout 10 is opened. And here, the pouring spout 1 is operated by raising and lowering the oil filling lid 41.
The opening and closing of 0 is performed by reversing the biasing direction of the spring 56, which is bent in the middle, so that the oil filling lid 41 is biased in both directions at the middle of the tilting angle range. In other words, both the state in which the spout 10 is closed and the state in which the spout 10 is opened are held by the spring 56. Further, the oil filling lid 41 here is prevented from opening further than the state shown in FIG. 7 by engaging with the wall surface surrounding the recess 55.

Now, an oil purifying section A consisting of two types of filter bodies 2 and 3 is arranged in the upper part of the container 1. is installed inside. Case 8 has multiple r/L from the upper end to the lower end.
It has a cylindrical shape whose diameter gradually decreases over stages, and is attached to the container 1 by being fitted into the cylindrical portion 13 of the ring body 11.

The filter body 2 is formed by molding paper into a cylindrical shape with a bottom, has a large number of vertical folds around the circumference, and is housed in the case 8. The other filter body 3 is configured as a cartridge by storing activated carbon in an oil purifying case 30 that is cylindrical and made of metal such as aluminum and has holes for passing oil through the upper and lower surfaces. It is attached to the case 8 by placing the 7 langes 31 on the upper edge of the oil purifying case 3o on the stepped portion 82 surrounding the small-diameter lower end opening of the case 8, and by placing the case 8 in the container 1, the filter body 2 is installed in the container 1.

The oil purifying section A, which is constructed by attaching both the filter bodies 2 and 3 to the case 8, is housed in the container 1 while being supported by the ring body 11, and as described above, Cylindrical portion 1 of ring body 11 into which case 8 is fitted
3 is located near the handle 7 on the opposite side of the spout 10, so the case 8 that can be attached here
The filter bodies 2 and 3 are similarly installed at positions closer to the handle 7 side. For this reason, between the outer surface of the case 8 and the inner surface of the container 1 on the spout 10 side, there is an oil storage part B, which is the lower part of the container 1, and the spout 10. A flow path connecting the container 1 can be secured without inflating a part of the container 1 to the outside. Also, a flow path with a sufficient cross-sectional area is formed between the spout 10 and the ring body 11 due to the presence of the recess 12 provided in the ring body 11.

Now, in the oil purifier configured in this way, with the lid 4 removed, oil used for tempura etc. is poured into the oil purifier and filtered in the oil purifying section A.
The oil is first filtered through filter body 2, which is a paper filter, to remove fine impurities such as scum and sludge, and then filtered through filter body 3.
Coloring components, odors, etc. are adsorbed and removed while passing through. As described above, the filter body 2 is provided with a large number of pleats to increase its surface area, so that a large amount of oil can be poured in at once, and the filtration time can be shortened.

The oil that has passed through the filter bodies 2 and 3 in this manner is stored in the oil storage section B, which is the lower part of the container 1. The above-described series of oil purifications is possible even if M4 is inserted immediately after the oil is added, because air is circulated to the outside through the spout 10 or the like.

When reusing the oil stored in the oil storage part B, it is only necessary to open the oil filling lid 41 instead of opening the entire lid 4. When the oil filler lid 41 is opened, the oil filler lid 41 is held in that state by the spring 56, so that even if the container 1 is tilted, the oil filler lid 41 remains open.
will never close. Then, if you tilt container 1,
The oil passes through the flow path between the inner surface of the container 1 and the outer surface of the case 8, and flows out from the spout 10. At this time, even if the container 1 is tilted significantly, the lid 4 will not come off because the main cover 40 is fixed to the container 1 as described above. Of course, the oil purifying section A will not come off.

On the other hand, the oil flowing out from the spout 10 is
He is gamma-ided and leaves. This oil filler fitting 15 is provided to prevent oil from dripping from the spout 10, and even if oil drips all over the outer surface of the oil filler fitting 15,
This oil enters the gap 17 between the oil filler fitting 15 and the inner surface of the spout 10, and then flows into the oil reservoir B through the small gap between the lower light of the oil filler fitting 15 and the protrusion 16 on the inner surface of the spout 10. return.

This means that the oil will not drip onto the outer surface of the container 1.

When replacing the filter body 2.3, the large diameter portion 80 at the upper end of the case 8 protrudes above the cylindrical portion 13 of the ring body 11, and the outer surface of the large diameter portion 80 of the case 8 and the ring body 11 As is clear from Fig. 3, there is a space between the inner circumferential surface of the upper half and the inner circumferential surface of the upper half, which allows you to insert your fingers. All you have to do is grab the upper end of the case 8 using the space and pull out the entire case 8.

[Effects of the Invention] As described above, in the present invention, since the oil purifying section arranged at the upper part of the container is provided offset to the side opposite to the spout formed at the upper end of the container, A flow path connecting the oil storage section at the bottom of the container and the spout can be secured between the inner surface of the container and the oil purifying section without inflating a part of the container outward. As a result, it is possible to eliminate irregularities on the outer surface of the container, thereby reducing the adhesion of oil and dirt, and even if it becomes dirty, it is easy to clean, making it good in terms of hygiene. Further, since the container has fewer irregularities, there is no problem in workability even when the container is made of metal, and the cost is also reduced.
