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 deep drawing process, which takes time and effort and increases the risk of damage during the process.

For this purpose, an oil purifier as shown in FIGS. 10 and 11 has been proposed. This consists of an oil storage case 1 that opens upward, an oil purification case 2 that is stacked on top of the oil storage case 1, and a lid 5 that closes the top opening of the oil purification case 2. The oil storage case 1 to which the oil storage case 10 is fixed has a beak part 41 as a spout in its upper part.
An inner cylinder 4 having a shape 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 reusing the oil purified by this oil purifier, the oil purification case 2 is removed and the oil in the oil storage case 1 is poured out from the beak 41. becomes a problem. When there is still unpurified old oil in the oil purification case 2, even more care must be taken to avoid oil stains because the purified oil will drip.

[Objective of the Invention] The present invention has been made in view of the above-mentioned points, and its purpose is to be careful about the place where the oil purification case is placed when removed and the dirt caused by oil dripping from the oil purification case. Our goal is to provide an oil purifier that you don't need to use.

[Disclosure of the Invention] The present invention provides an oil storage case that opens upward, an oil purification case that is polymerizable on the oil storage case, and a filter body is disposed at the bottom, and an oil purification case. An oil purifier comprising a removable lid that closes a top opening, characterized in that the lid is provided with a holding cylinder that fits into and covers the outlet of purified oil in the oil purification case. The oil purification case can be placed on top of the lid, and at this time, the outlet of the purified oil in the oil purification case is closed.

The present invention will be described in detail below based on the illustrated embodiments. The oil storage case 1 consists of a lid 5 that closes the opening, opens upward, and has a handle 10 fixed to its outer peripheral surface via a mounting bracket 15. An inner cylinder 4 is removably press-fitted into the upper part of the oil storage case 1. ing. 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 peripheral surface of the oil storage case 1 and protrudes inward. The upper end of the inner cylinder 4 that 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 purifying case 2 has a cylindrical shape with a handle 20 provided on the outer circumferential surface via a mounting bracket 25, and the diameter of the lower part is reduced in two stages, so that there are two stepped surfaces 21, 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 a 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 caulked and fixed to the upper opening of the case 31. The flange 34 is fitted into 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, and the upper edge of the oil storage case 1 and the purifying oil A slight gap δ is left between the case 2 and the case 2. still,
Cover 24 attached to the bottom of the oil purification case 2
This covers the beak 41 and prevents insects and dust from entering the oil storage case 1 from the beak 41.

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.
stored within.

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 a in the figure, after entering the gap, the oil is located slightly between the inner cylinder 4 and the annular protrusion 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
5, by passing both ends through a pair of cut and raised portions provided in the ring body 35, holding the arc-shaped handle 39 which is rotatably attached to the ring body 35, and pulling the ring body 35 upward. All that is required is to replace the paper 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 lid 5 that covers the top opening of the oil purification case 2 has a flat top surface, and a cylindrical holding cylinder 50 on the inside as shown in FIGS. 2 and 4. The handle part 5 is protruded and covers the top surface of the handle 20 of the oil purifying case 2.
