Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to an oil purifier for filtering contaminated edible oil such as tempura oil that has been used or is in the process of being used, and removes impurities such as residue. It is.

[Background Art] 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 opening provided at the top of the container, passing the oil through the oil purification section into the oil storage section, and then tilting the container to pour out the oil stored in the oil storage section. There is.

By the way, when filtering oil, fried residue, color, odor, etc. can be removed in the oil purification section, but it is difficult to completely remove fat from fried seeds that have dissolved in the oil. Even if you do this, fat will enter the oil storage area, and
As the oil cools, this fat becomes sludge-like and accumulates at the bottom of the oil reservoir.

On the other hand, in the above conventional example, the container 1 has a cylindrical shape with a constant inner diameter, and the container 1 has a bulging portion on the upper side surface in which the oil purifying portion A is housed, the upper end of which is the spout 10. Therefore, when the container 1 is tilted and the oil in the oil storage part B is poured out in order to reuse the oil stored in the oil storage part B, as shown in FIG. However, there is a problem in that impurities such as the sludge-like fat accumulated at the bottom of the oil storage part B flow out at the same time.

[Object of the Invention] The present invention has been made in view of the above points, and its purpose is to drain the bottom of the oil storage part when pouring out the oil stored in the oil storage part for oil reuse. To provide an oil purifier from which impurities accumulated in the oil do not flow out.

[Disclosure of the Invention 1 The present invention provides an oil purification section in the upper part of a container whose lower part is an oil storage section, and an opening for introducing oil into the upper end of the container and an opening for taking out the oil. The oil purifier is characterized in that the diameter of the lower part of the container in which the oil storage part is provided is larger than the diameter of the upper part of the container in which the oil purification part is provided. When pouring out the oil stored in the oil storage part by tilting the container, the four parts created on the inner surface of the lower part of the container due to the difference in diameter prevent impurities from flowing out, so that only the supernatant in the oil in the oil storage part flows out. This is what I did.

The present invention will be described in detail below based on the illustrated embodiments. This oil purifier has a bottomed cylindrical shape with a lower part serving as an oil storage part B, and has an upper part inside a container 1 with a lid 4 attached to the upper opening. , an oil purifying section A consisting of two types of IT passage bodies 3 is arranged. First, the container 1 is explained. This is a pedestal 6 on the lower surface of a bottomed cylindrical body with a slightly bulged lower part. It is made of metal such as stainless steel or aluminum, and the top end has a spout 1 that is partially inflated to the outside.
0, and a handle 7 is attached to the portion opposite to the spout 10.

The pedestal 6 made of synthetic resin has a mounting plate 60.
It is attached to the bottom surface of the container 1 via. The mounting plate 60, which is fixed to the lower surface of the periphery of the container 1 by means such as spot welding, has several countersink parts 67 with internal threads, as shown in FIG. The pedestal 6 is attached to the container 1 by a screw 69 screwed into the counter sink part 67. A convex part 18 that is slightly bulged inside is provided at the center of the bottom surface of the container 1. The tip is located in a heat-insulating space 19 formed on the lower surface of the container 1 by providing the convex portion 18 .

The handle 7 made of synthetic resin is attached to the container 1 via a pair of upper and lower handle fittings 76,76. Each handle fitting 76 has its base end fixedly welded to the container 1, and has a countersink part 77 with an internal thread cut on its distal end surface, and a screw screwed into the countersink part 77. The handle 7 attached to the container 1 by the handle 78 includes a space 71 into which fingers can be inserted, and a partition piece 72 that partitions between this space 71 and the outer peripheral surface of the container 1. It is designed to prevent it from coming into contact with the outer peripheral surface. Also, a partition piece 72 formed integrally with the handle 7
The handle 7 itself does not come into contact with the outer circumferential surface of the container 1, leaving an insulating space 73 in between, so even when there is hot oil in the container 1, your fingers and fingers holding the handle 7 will not get burned. I don't have any strong feelings or feelings.

Next, the structure of the container 1 will be explained. This container 1 has a cylindrical shape with a bottom and a spout 10 formed in a part of the upper end.As described above, the lower part is slightly rounded so that the diameter L2 of the lower part is larger than the diameter L1 of the upper part. A circular ring body 11 made of metal such as stainless steel or aluminum is fixed along the inner circumferential surface of the upper part, and an oil filler fitting 15 is removably inserted into the spout 10. ing. The ring body 11 has four parts 12 on the outer surface of the portion corresponding to the spout 10, and has an upper half that is fixed to the inner peripheral surface of the upper end of the container 1, and a lower half that has a smaller diameter than the upper half. The cylindrical part 13 of the lower half, which is continuous with the upper half via a step, is formed as a two-stage cylinder consisting of a side opposite to the spout 10 with respect to the upper half and the container 1; In other words, it is deviated toward the handle 7 by the dimension indicated by e in the figure. Further, on the inner circumferential surface of the upper half of the ring body 11 and the above-mentioned concave fff+
a pair of protrusions 1 protruding inward in proximity to 12;
4.14.

The spout 10, whose upper end is cut off diagonally, is formed by expanding a part of the upper end of the container 1 outward, as described above, and the oil spout fitting 15 is attached to the spout 1.
It is inserted until the lower end comes into contact with a protrusion 16 protruding from the inner surface of 0. The oil filler fitting 15 has a semicircular horizontal cross section, and the curvature of the horizontal cross section increases upwardly. Spout 1 cut off by
0 and creates an empty IFIX 17 with the inner surface of the upper end of the spout 10.

The lid 4 that closes the upper opening of the container 1 is composed of two parts: a main cover 40 and an oil filler cover 41 attached to the main cover 40. The head 40, which has a knob [44 integrally protruding from the side opposite to the attachment part of the oil filler lid 41,
A notch 58 for positioning the lid 4 between the recess 12 of the ring body 11 and a notch 58 on the mounting side of the ring body 11.
It is provided with a hanging piece 42 in contact with the inner surface of the upper half, and the protrusion 14 is engaged with four parts 43 formed on the hanging piece 42, and a pair of lock buttons 45 provided on the knob part 44 are provided. .45 engages with an engaging portion 74 disposed on the upper end surface of the handle 7, the main handle 40 is attached to the container 1.

The oil filler lid 41 is attached to the main cover 40 by locking one end of a spring 56 made of stainless steel or the like disposed in a recess 55 formed in the main cover 1 to the lower surface of one end of the oil filler cover 41. When 41 is pushed down, the spout 10 is closed to prevent dirt, dust, insects, etc. from entering, and when it is raised, the spout 10 is opened. The opening and closing of the spout 10 by the tilting operation of the oil filler lid 41 is performed by reversing the biasing direction of the spring 56, which is bent in the middle, at the middle of the tilting angle range of the oil filler lid 41. It is biased in both directions. 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.

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

[The overbody 2 is formed by molding paper into a cylindrical shape with a bottom, has a large number of longitudinal folds locally, 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. The 7-run no. 31 on the upper edge of the oil purifying case 30 is placed on the stepped portion 82 surrounding the small-diameter lower end opening of the case 8 (thereby, it is attached to the case 8, and by housing 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 2.3 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 (II!l) on the opposite side of the spout 10, so the case 8 and filter body 2.3 attached here are also attached to the handle 71111I.
It is installed in a position close to the 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 two is ensured. 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 an oil purifier configured like this! 14
With the removed, pour in the oil used for tempura, etc., and put it in the oil purification section A! At this time, fine impurities such as dirt and sludge are removed from the oil by the filter body 2, which is a bug-free paper filter, and then, while passing through the filter body 3, coloring components and odors are removed. etc. are adsorbed and removed. As described above, the filter body 2 is provided with a large number of folds to increase its surface area, so that a large amount of oil can be poured in at once, and the opening time during filtration 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 the lid 4 is closed immediately after the oil is added, because air is circulated to the outside through the spout 10 and 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 in the oil storage part B 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. Even if the container 1 is tilted outward, the lid 4 will not come off because the main M40 is fixed to the container 1 as described above. Of course, the oil purifying section A will not come off.

When pouring out this oil, since the diameter L2 of the lower part of the container 1 which is the oil storage part B is larger than the diameter of the upper part where the oil purification part A is arranged, the container 1 must be placed right sideways. Even in the tilted state, as shown in FIG. 5, the entire amount of oil in the oil storage portion B does not leak out. In other words, what flows out by tilting container 1 is the oil that was in the upper layer of the oil storage part B, and the oil and impurities at the bottom of the oil storage part B are caused by the difference in diameter mentioned above. It stays in the four parts on the lower inner peripheral surface of the container 1 and remains without flowing out. Precipitated impurities can be separated, and impurities that accumulate at the bottom after long-term use can be removed by periodic cleaning.

On the other hand, the oil flowing out from the spout 10 is
He is forced to leave. This oil filler fitting 15 is provided to prevent oil from dripping from the spout 10, and even if oil drips down 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 returns to the oil reservoir B through the small gap between the lower end of the oil filler fitting 15 and the protrusion 16 on the inner surface of the spout 10. .

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

When replacing the tll overbody 2.3, the large diameter part 80 at the upper end of the case 8 protrudes above the cylindrical part 13 of the ring body 11, and the outer surface of the large diameter part 80 of the case 8 and the ring body 11 As is clear from Fig. 2, there is a space between the inner circumferential surface of the upper half and the inner circumferential surface of the upper half, which allows the fingers to be inserted. All you have to do is grab the upper end of the case 8 using the space and pull out the entire case 8.

Incidentally, in order to facilitate the cleaning of impurities accumulated at the bottom of the oil storage part B, it is preferable that the bottom corner of the container 1 has a large radius of curvature, but if it has such a curved surface, If a shock is applied, such as when the product is dropped while in use, the weight of the oil will also be added, making it more likely to be damaged or deformed. In order to prevent this, as shown in FIG. It is best to make sure that the entire curved surface can receive it.

[Effects of the Invention] As described above, in the present invention, since the diameter of the lower part of the container where the oil storage part is provided is larger than the diameter of the upper part of the container where the oil purification part is provided, it is possible to tilt the container. When pouring out the oil stored in the oil storage section, the impurities accumulated at the bottom of the oil storage section remain in the recess created on the inner surface of the lower part of the container due to the difference in diameter, and only the supernatant in the oil in the oil storage section flows out. It is a material that does not allow impurities to flow out.
