Description

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

[Background technology]

As shown in Japanese Utility Model Application Publication No. 7-64246, conventional oil purifiers have an opening for introducing oil and a spout for taking out oil in a single lid. In this case,
The lid is designed to be easy to open and close in case the oil is poured out, so if the container is tipped over, there is a risk that the lid will come off or open wide, causing all the oil to spill out. Moreover, the oil cannot be poured out without opening the lid completely, which is troublesome and increases the risk of dirt and dust getting inside, which is unhygienic.

[Purpose of the invention]

The present invention was developed in view of these points, and its purpose is to enable only the spout to be opened when pouring out oil, and to remove the lid that closes the opening each time. Our goal is to provide an oil purifier that eliminates the need for oil purifiers.

[Disclosure of the invention]

Accordingly, the present invention provides an oil purification system in which a filter is provided in the upper part of the container, an oil storage part is provided in the lower part, and an opening for introducing oil into the upper end of the container and a spout for taking out the oil are provided. The container includes a main lid that closes an opening that communicates with the oil reservoir through the filter, and an oil filler lid that closes the spout that leads to the oil reservoir without going through the filter, and the oil filler lid is integrated with the main lid. In addition, it is characterized by being able to be opened and closed independently from the main lid, and the opening for pouring in oil and the spout for pouring out oil are made independent, and the main lid and oil filler lid are separated from each other. In addition to opening and closing with the main lid, an oil filler lid is provided on the main lid.

The present invention will be described in detail below based on the illustrated embodiment. This oil purifier has three types of filter bodies 1, 2 and 3, and first we will explain about the container 5. This consists of press-fitting and welding a disk that will become the bottom plate to the bottom of a cylindrical body with the part that will become the spout bulging outside. It is formed into a cylindrical shape with a bottom, and is made of metal such as stainless steel or aluminum. A pedestal 6 is attached to the lower surface of the bottom plate, and the pedestal 6 is attached to the bottom of the bottom plate, opposite to the part of the circumferential surface where the bulge 54 that serves as the pouring spout is formed. A handle 7 is attached to the side.

A pedestal 6 made of synthetic resin is attached to the lower surface of the bottom plate of the container 5 via a bottom plate metal fitting 60. The bottom plate fitting 60 has a hole 66 that engages with a positioning projection 65 protruding from the bottom surface of the bottom plate of the container 5.
It also has several countersink parts 67 with female threads cut on the periphery and a fitting hole 68 in the center, and the protrusion 61 in the center of the base 6 is connected to the fitting hole 68. The pedestal 6 is positioned by fitting into the counter sink part 67.
It is fixed to the container 5 via the bottom plate fitting 60 by screws 69 screwed into the bottom plate.

Both handles 7 have a main body 70 made of synthetic resin.
and a cover 71, and is attached to the container 5 via a pair of upper and lower handle fittings 76, 76. Each handle fitting 76 has its proximal end fixedly welded to the container 5 and has a countersink part 77 with a female thread cut on the distal end surface, and the main body part 70 is fixed by a screw 78. The handle fitting 76 and the cover 71 are attached to the main body part 70 with screws 79. Here, the main body part 70 forms a space 74 between the pair of upper and lower handle fittings 76, 76 into which fingers can be inserted, and between this space and the outer peripheral surface of the container 5, the main body part A partition piece 72 formed integrally with the handle 70 is positioned to prevent the fingers gripping the handle 7 from coming into contact with the outer circumferential surface of the container 5, and the partition piece 72 itself is also placed on the outer circumferential surface of the container 5. Since there is no contact between them and a heat insulating space 73 is provided between them, even when there is high temperature oil in the container 5, the hands and fingers holding the handle 7 may get burned or feel hot. It is made sure that there is no such thing. Furthermore, the upper end of the handle 7 forms a space 75 that is open upward and on both sides between the upper end of the upper handle fitting 76 and the outer peripheral surface of the container 5. The knob 14 of the filter body 1 can be accommodated in this space 75.

Next, the structure of the container 5 will be explained. This container 5, which has a cylindrical shape with a bottom and a spout portion formed as a bulging portion 54, has a circular ring body 50 made of metal such as stainless steel or aluminum along its upper inner circumferential surface. is firmly fixed, and an oil filler fitting 55 is removably inserted into the spout. The ring body 50
is a structure in which upper and lower annular projections 51 and 52 and a plurality of projections 53 located above these annular projections 51 and 52 protrude inward. The section 51 has a trapezoidal cross section, and the lower annular protrusion 52 has a semicircular cross section. It is divided into a spout portion formed as an outlet 54. still,
The upper end of the container 5 and the upper end of the ring body 50 are cut out at the portions facing the space 75 of the handle 7.

The bulging portion 54 serving as a spout is formed from a position slightly below the vertical center of the container 5 to the upper end of the container 5, and the upper end is cut off diagonally. The oil filler fitting 55 is inserted therein as described above. Swelling part 5
The oil filler fitting 55, which is inserted until its lower end abuts on a protrusion 56 protruding from the inner surface of the oil filler 55, has a semicircular horizontal cross section, and the curvature of the horizontal cross section increases upward. When inserted into the spout, it protrudes above the upper end of the bulged portion 54 cut off as described above, and creates a gap 57 between it and the inner surface of the bulged portion 54.
It has become something that gives rise to

The lid 4 that closes the upper end opening of the container 5 formed as described above is composed of two parts: a main lid 40 and an oil filling lid 41. The main lid 40 has a seal ring 42 attached to its outer circumferential surface that is in contact with the inner circumferential surface of the ring body 50, and the seal ring 42 that contacts the inner circumferential surface of the ring body 50 is fitted into the ring body 50 and rotated to prevent the above-mentioned protrusions in the ring body 50. A plurality of engagement grooves 43 that engage with the portion 53 are formed on the outer circumferential surface, and a pair of semicircular recesses that become deeper toward the center are provided at intervals on the upper surface. It is provided with a knob part 44 formed between the recesses, and further includes a knob part 4 on the upper surface.
4 is provided with a recess 45 at one end side.

As shown in FIGS. 5 and 6, the oil filler lid 41 has a pair of shafts 47 that project laterally from the outer surface of the oil filler lid 41, and is formed in the side wall of the recess 45 in the main lid 40. One end of a spring 46 made of stainless steel or the like is placed in the recess 48 of the main lid 40 and is secured to the lower surface of the oil filler lid 41, and when the oil filler lid 41 is tilted down, the oil is poured. The spout is closed to prevent dirt, dust, insects, etc. from entering, and the spout opens when raised. The opening and closing of the pouring spout by the tilting operation of the oil filler lid 41 is performed in both directions by reversing the biasing direction of the spring 46, which is bent in the middle. It has become something that is strongly influenced by In other words, the spring 46 holds both the spout closed state and the spout open state. Furthermore, this operation is possible due to the biasing force of the spring 46 toward the inner wall of the recess 45 and the fact that the shaft 47 is movable within the recess 48.
The corner of the oil filler lid 41 contacts the inner wall surface of the recess 45 to provide a click property.

In addition, when attaching and detaching the main lid 40, since the oil filler lid 41 provided on the main lid 40 is shaped to cover the spout, the engagement between the protrusion 53 and the engagement groove 43, Alternatively, the operation of rotating the main lid 40 to release the engagement requires raising the oil filling lid 41 and keeping the spout open. And a seal ring 42 provided on the main lid 40
Due to the presence of the seal ring 42, even if the main lid 40 is tipped over while attached to the container 5, there is almost no oil leakage.Furthermore, since the seal ring 42 has a V-shaped cross section, The seal ring 4 has low resistance to rotation for attaching and detaching the lid 40.
2, it can be easily attached and detached, and a ring body 50 is located on the spout side of the main lid 40 to prevent oil from coming into contact with the main lid 40. Because of this, it has become sanitary.

Now, three types of filter bodies 1, 2, and 3 are arranged in the container 5, and the filter body 1 is located at the bottom opening of an inverted semi-conical case 10 made of metal such as stainless steel or aluminum. 30-40 mesh wire mesh 1
1, and a wire mesh handle 13 provided with the knob 14 is attached by welding. Note that the knob 14 is made of synthetic resin, heat-resistant rubber, or the like.

The filter body 2 is formed by molding paper into a cylindrical shape with a bottom, and in particular has many vertical folds formed on the circumferential surface.The filter body 2 is arranged in a cylindrical case 8. and is housed in the container 5. The remaining filter body 3 is configured as a cartridge with activated carbon 33 as the main member for filtration, and is an oil purification case made of metal such as aluminum and has a cylindrical shape with a bottom and has many holes in the bottom. 30, a non-woven fabric filter 3 whose upper and lower parts are made of polyester, etc.
Activated carbon 33 is stored in a state sandwiched between 1 and 32, and a perforated upper plate 34 such as punched metal is fixed to the upper opening of the oil purifying case 30 by caulking. It is stored in the container 5 in the installed state. The activated carbon 33 is the non-woven fabric filter 31, 32
Due to the presence of , there will be no leakage.

The case 8 is housed in the container 5 by having its upper edge locked onto the annular protrusion 51 of the ring body 50. An arc-shaped hanger 81 is attached to the upper part, and a lower part is provided with an arcuate handle 81. A small diameter cylindrical portion 83 is formed through the tapered surface 82, and this small diameter cylindrical portion 8
3. An annular packing 84 having oil resistance is installed on the inner peripheral surface. The filter body 3 formed as a cartridge is housed in the case 8 from above, and the flange portion of the upper end of the oil purifying case 30 is brought into contact with the packing 84, so that the filter body 3 is disposed in the small diameter cylindrical portion 83. The filter body 2 is a paper filter.
is arranged at the upper portion having a large diameter, with its lower end peripheral edge resting on the tapered surface 82 of the case 8. At this time, spaces are created between the outer circumferential surface of the filter body 2 and the inner circumferential surface of the case 8, and between the lower surface of the filter body 2 and the upper surface of the filter body 3.

The filter bodies 2 and 3 are attached to a case 8 in which they are attached.
into the container 5 and the ring body 50 as described above.
The case 8 is installed in the container 5 by supporting the case 8 by the annular protrusion 51 . In addition, filter body 1
The upper end flange of the case 10 is connected to the case 8.
It is placed in the container 5 while being locked to the upper edge, and the wire mesh handle 13 is passed through the notch in the container 5 and the ring body 50 to position the knob 14 in the space 75 of the handle 7. let Furthermore, at this time, the case 10 in the first filter body 1
enters the inside of the second filter body 2 housed inside the case 8. The second is a paper filter
This prevents the filter body 2 from falling down.

Now, in the oil purifier configured in this way, the oil used for tempura etc. is poured with the lid 4 removed. At this time, the oil is first passed through the first filter body 1 which is a wire mesh. After removing relatively coarse impurities such as fried residue, it passes through the second filter body 2. After fine sludge-like impurities are removed by the filter body 2, which is a paper filter, the presence of the packing 84 ensures that the third
It passes through the filter body 3. In addition, since the inner diameter of the filter body 2 is made larger than the diameters of the filter bodies 1 and 3, and the filter body 2 is provided with a large number of pleats as described above to increase the surface area, a large amount of Not only can oil be poured in at once, but the filtration time can be shortened, and even when a large amount of oil is poured at once, the case 10 in the filter body 1 prevents the filter body 2 from falling over. for,
Oil passes through the filter body 2 reliably. Furthermore, the tapered surface 8
2 is provided in the case 8, and the packing 8
4 is located below the tapered surface 82, so that oil does not remain in the case 8.

The oil that has reached the filter body 3 is diffused when passing through the upper plate 34 and the nonwoven fabric filter 31, and while passing through the layer of activated carbon 33, coloring components, odors, etc. are adsorbed and removed. In addition, non-woven filter 3
Due to the presence of 1 and 32, there is no possibility that activated carbon 33 will be mixed into the purified oil. The oil that has passed through each of the filter bodies 1, 2, and 3 in this manner is stored in an oil storage tank located at the lower part of the container 5. The above-described series of oil purifications is possible even when the lid 4 is closed because air is circulated with the outside through the cutout for passing the wire mesh handle 13.

When reusing the oil stored in the oil storage tank, 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 46, so that the oil filler lid 41 will not close even if the container 5 is tilted. Then, if the container 5 is tilted, the oil will flow into the bulging part 54.
and the case 8, and flows out from the spout. At this time, even if the container 5 is tilted greatly, the main lid 4
0, since the seal ring 42 is in pressure contact with the inner surface of the ring body 50, the entire lid 4 or the filter body 1 will not come off, and the oil will not flow back through the filter bodies 1, 2, and 3. Even if such a situation occurs, the presence of the seal ring 42 prevents oil from overflowing from areas other than the spout. On the other hand, the oil flowing out from the spout is guided by the oil filler fitting 55 and exits. This oil filler fitting 5
5 is provided to prevent oil from dripping from the spout, and even if oil drips down the outer surface of the oil filler fitting 55, this oil will flow between the oil filler fitting 55 and the inner surface of the bulging portion 54. It then returns to the oil storage tank through a small gap between the lower end of the oil filler fitting 55 and the protrusion 56 on the inner surface of the bulge 54. This prevents oil from dripping on the outer surface of the container 5.

〔Effect of the invention〕

As described above, in the present invention, the lid is composed of the main lid that closes the opening of the container and the oil filler lid that closes the pouring spout, and when pouring out oil, it is only necessary to open the small oil filler lid. There is no need to remove the main lid or filter, and even if the container is toppled over, the opening will be closed by the main lid, and the main lid will keep the oil out. To facilitate the operation of pouring out the
Since it does not need to be easily removed, it can prevent oil from flowing out, and it also has an opening that communicates with the oil storage area through the filter, and an opening that communicates with the oil storage area without going through the filter. Although it has two openings that are independent of each other with a pouring spout that communicates with it, the oil filler lid and the main lid that close these spouts and the opening, respectively, are formed integrally.
When pouring oil into the container, the main lid and the oil filler lid can be removed at the same time, making handling easier.Also, since the oil filler lid is also removed at the same time, the oil filler lid does not contain oil when pouring oil. It will not get dirty.
