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.

[Background Art] Since oil easily deteriorates when exposed to light, the case of an oil purifier that removes oil color, odor, etc. through filtration is often made of metal. The metal case is manufactured by drawing a metal plate, but even though the amount of oil stored is not very large, a space is required above the oil storage part to accommodate the filter. The case is quite deep, and therefore the drawing process is quite a deep drawing process, which is time-consuming and increases the risk of damage during the process.

For this purpose, an oil purifier as shown in FIGS. 14 and 15 has been proposed. This consists of an oil storage case 1 that opens upward and an oil purification case 2 that is stacked on top of this oil storage case 1. Beak part 4 as a spout inside
An inner cylinder 4 having a number 1 formed thereon is removably press-fitted therein. On the other hand, the oil purification case 2 has a cylindrical shape with a handle 20 on its outer circumferential surface, and includes a filter body 3A equipped with activated carbon 30 and a filter body 3A equipped with a paper filter 36.
B is stored.

In an oil purifier with a case divided into upper and lower halves like this, there is no need for deep drawing.
The above problems have disappeared. However, by dividing into two, the following new problems arise. In other words, when carrying this oil purifier or taking it in and out of the shelf, place the oil purifier case 2 on top of the oil storage case 1.
With the oil storage case 1 stacked, hold the handle 10 provided on the oil storage case 1. At this time,
There is a high risk of touching the oil purification case 2 or the handle 20 to other objects and having to replace the oil purification case 2, especially if used oil accumulates inside the oil purification case 2 during oil purification. It is dangerous to replace the oil purifying case 2, such as when storing it in a hot state, as hot oil will flow out. In addition, when there is oil in the oil purifying case 2, the center of gravity G as shown in FIG.
Because the oil purifier case is high and unstable, it is difficult to carry it in a horizontal position, and even the slightest inclination means that the oil purifier case has to be replaced.

[Object of the Invention] The present invention has been made in view of the above points, and its purpose is to improve the ease of transportation in a product consisting of an oil storage case and an oil purification case stacked on the oil storage case. Good stability,
To provide an oil purifier with improved safety.

[Disclosure of the Invention] The present invention provides an oil purifier comprising an upwardly opened oil storage case and an oil purification case that can be freely polymerized on the oil storage case. It is characterized in that the handle and the second handle provided on the oil purifying case are provided with engaging parts that engage with each other, and by engaging both handles, the oil storage case and the second handle are stacked on the oil storage case. It has a high degree of connection with the oil purification case.

The present invention will be described below in detail based on the illustrated embodiment. This oil purifier consists of an oil storage case 1 and an oil purification case 2, both of which are made of metal such as stainless steel or aluminum. The oil storage case 1 is open and has a handle 10 fixed to its outer peripheral surface, and an inner cylinder 4 is removably press-fitted into the upper part of the oil storage case 1. The inner cylinder 4 made of metal such as stainless steel or aluminum is placed on an annular convex portion 11 formed on the upper inner circumferential surface of the oil storage case 1 and protrudes inward. The upper end of the inner cylinder 4, which protrudes upward from the upper opening edge of the case 1, has an outer diameter smaller than the inner diameter of the oil storage case 1, and a beak 41 as a spout is formed in a part. has been done.

On the other hand, the oil purification case 2 has a cylindrical shape with a handle 20 on its outer circumferential surface, and the diameter of the lower part is reduced in two stages, so that there are two stepped surfaces 21 and 22.
and a small diameter cylindrical portion 23 are formed. Two types of filter bodies 3A and 3B are housed within this oil purifying case 2.

The filter body 3A is of a cartridge type and is equipped with activated carbon 30 as the main member for filtration. Activated carbon 30 is housed between filters 33 made of non-woven fabric such as, and an upper plate 32 with holes such as punched metal is fixed to the upper opening of the case 31 by caulking. The flange 34 is fitted onto the small diameter cylindrical portion 23 while being placed on the stepped surface 22 of the oil purifying case 2.

The filter body 3B includes a ring body 35 made of metal such as stainless steel or aluminum and a paper filter 36.
The paper filter 36 is attached to the ring body 35 by placing the paper filter 36 in the lower opening of the ring body 35 and attaching the peripheral edge of the paper filter 36 to the outer peripheral surface of the ring body 35. Attach the ring-shaped spring 37 in this state.
This is done by fitting the paper filter 36 into the groove 38 on the outer peripheral surface of the ring body 35 from above. The filter body 3B is installed on the stepped surface 21 by being lightly press-fitted into the oil purifying case 2.

The oil purification case 2 is placed on top of the oil storage case 1, and the pair of step surfaces 21 and 22 of the oil purification case 2 are placed inside the upper end opening of the inner cylinder 4 attached to the oil storage case 1. The cylindrical portion between the two is fitted into each other. In other words, the upper edge of the inner cylinder 4 receives the lower surface of the stepped surface 21 of the oil purifying case 2, so that the oil purifying case 2 is stacked on the oil storage case 1. A slight gap δ is provided between the case 2 and the case 2.

However, in this oil purifier, the oil purifier case 2
The lid 5 placed over the top opening is removed and the oil used for tempura etc. is poured in. At this time,
The oil first passes through the paper filter 36, which is the filter body 3B, and after removing fine impurities such as fried crumbs and sludge, the oil passes through the filter body 3A. At this time, the upper plate 32
The oil is diffused when passing through the non-woven fabric filter 33, and while passing through the layer of activated carbon 30, coloring components, odors, etc. are adsorbed and removed, and then the oil is transferred to the oil storage case 1.
Can be stored within 1.

Ring body 3 to which paper filter 36 is attached
Although the outer diameter of the oil filter 5 is slightly smaller than the inner diameter of the oil purifying case 2, the fit is made so that there is no looseness, so the oil passes through the paper filter 36 reliably and then flows into the filter body 3A. Head towards. In addition, paper filter 3
6 is effective in preventing clogging of the nonwoven fabric filter 33. In addition, the nonwoven fabric filter 33 includes activated carbon 3
To prevent oil from flowing out and mixing with oil stored in an oil storage case 1. In addition, this series of purifications
Even when the lid 5 is closed, air can circulate smoothly in the gap between the oil purifying case 2 and the lid 5.

During the above oil purification work, remove the oil from the oil purification case 2.
Even if oil accidentally adheres to the outer surface of the oil purifying case 2 when pouring it into the interior, the oil will flow through the inner cylinder 4 that is in contact with the oil storage case 1 and will be absorbed between the inner surface of the oil storage case 1 and the inner cylinder 4. It enters the space between the oil storage case 1 and the oil storage case 1 through a small gap between the inner cylinder 4 and the annular convex portion 11. It won't stain your face.

Also, when reusing the oil stored in the oil storage case 1, remove the oil purification case 2 and remove the oil stored in the oil storage case 1.
The oil is poured out from the spout 41 provided in the inner cylinder 4 by tilting it, but at this time,
Even if oil drips down the outer surface of the beak 41, a gap is provided between the beak 41 and the upper opening edge of the oil storage case 1, and the beak 41
Since the oil is located 2 to 3 mm inward from the upper opening edge as shown by α in the figure, after entering the gap, the oil is located slightly between the inner cylinder 4 and the annular convex portion 11. It returns to the inside of the oil storage case 1 through the gap.

When the paper filter 36 becomes dirty, the ring body 3
Hold the arc-shaped handle 39 which is rotatably attached to the ring body 35 by passing both ends through a pair of cut and raised portions provided in the ring body 5, and pull the ring body 35 upward to remove the paper. All you have to do is replace the filter 36. Filter body 3 in which activated carbon 30 has lost or decreased adsorption capacity
A is also assumed to be replaced with the entire cartridge. The filter 3A can be easily removed during this replacement by removing the oil purifying case 2 from the oil storage case 1, turning it upside down, and pressing the bottom surface of the filter 3A with a finger or the like.

Now, the handle 10 of the oil storage case 1 is fixed to the outer circumferential surface of the oil storage case 1 via the mounting bracket 15. Also protrudes upward, and a groove 16 is formed at least from the upper surface to the outer surface of the outer circumferential surface thereof.

The handle 20 of the oil purifying case 2 is fixed to the outer circumferential surface of the oil purifying case 2 via a mounting bracket 25, and is a free handle having a space between it and the outer circumferential surface of the oil purifying case 2. The grip portion 27, which is the end portion, protrudes downward from the lower surface of the oil purifying case 2, and a protrusion 26 that engages with the groove 16 of the handle 10 is formed on the inner surface. It has become a common thing.

Now, when the oil purification case 2 is superposed on the oil storage case 1, as described above, the pair of steps 21 and 22 of the oil purification case 2 are placed inside the upper end opening of the inner cylinder 4 attached to the oil storage case 1. Not only does the cylindrical portion between the two fit, but the handle 20 overlaps the handle 10, and as shown in FIG.
and the protrusion 26 on the inner surface of the handle 20 engage with each other to connect the oil purifying case 2 and the oil storage case 1. Even if the entire oil purifier is slightly tilted, the oil purifier case 2 will not be replaced.

Also, when stacked in this way, the grip part 27 of the handle 20 overlaps the handle 10, and both handles 10 and 20 form an integrated grip part, and when holding the entire oil purifier, Since you will be grasping not only the handle 10 on the oil storage case 1 but also the handle 20 on the oil purification case 2, it is unlikely that you will change the oil purification case 2 once while you are holding it. is the fifth position
As shown in the figure, since it is close to the center of gravity G of the entire oil purifier, no rotational moment is applied to the grip even if the oil purifier is tilted, and therefore it can be carried in a stable state. It is something that

Furthermore, when pouring out the oil in the oil storage case 1 from the beak 41 with the oil purification case 2 removed, the handle 1
The groove 16 on the top surface of the oil storage case 1 serves as a place to rest the thumb of the hand that grips the handle 10, which determines the position of the hand that grips the handle 10 of the oil storage case 1, and allows for accurate pouring of oil. can be done.

Other embodiments are shown in FIGS. 6 to 9. The internal structures of the oil purification case 2 and the oil storage case 1 are the same as those in the above embodiment, but the handle 2 of the oil purification case 2
0 is that the protrusion 26 is formed on the inner side,
The difference is that the handle 10 of the oil storage case 1 is similar to the handle 20 of the oil purification case 2. Although they are similar in shape, grooves 16 are provided on the upper and outer surfaces of the handle 10 to connect the protrusion 26 and the handle 1.
The groove 16 on the outer surface of the grip part 17 of 0 engages with the groove 16, and when both handles 10 and 20 are overlapped,
Both are integrated to form one grip.

10 to 13 show still another embodiment, in which both handles 10 and 20 are both U-shaped, and a groove 16 formed on the upper surface of the handle 10 is provided with a handle 20. Projection 2 formed on the lower surface of
6 is engaged.

[Effects of the Invention] As described above, in the present invention, the handle of the oil storage case and the handle of the oil purification case stacked on the oil storage case are engaged with each other, so that the oil purification cases are stacked. Even when holding the handle of the oil storage case, the oil purification case remains stable, and even if it is slightly tilted, the oil purification case does not change over, providing good stability and high safety. It is something.
