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 those caused by frying. It is something.

[Background Art] As shown in Japanese Utility Model Application Publication No. 57-64.246, a conventional oil purifier has an opening for introducing oil and a spout for taking out the oil. , which is opened and closed by a single lid, and in this case, the lid is easy to open and close in consideration of pouring out oil, so if the container is tipped over, the lid may be damaged. There is a risk that it will come off or the lid will open wide and all the oil will flow out.
Furthermore, the oil cannot be poured out without opening the whole indigo, which is not only troublesome but also unhygienic as there is a high risk of dirt and dust getting inside.

``Object of the Invention 1 The present invention has been made in view of the above-mentioned α, and its purpose is to enable only the spout to be opened and to close the opening when pouring out oil. The object of the present invention is to provide a container for purifying oil that does not require removing the indigo indigo one by one. In addition, in an oil purifier that has an opening for introducing oil and a spout for taking out oil at two ends of the container, an upper lid that closes the opening and an oil filler lid that closes the spout are provided. The feature is that the oil filler lid is provided in one piece and the oil filler lid is provided so that it can be opened and closed independently from the top cover.The top cover for the opening and the oil filler cover for the spout are provided, and the two are separated, and the oil filler lid is provided for the top cover. It has a 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.
First, let us explain about the container 5. This is achieved by press-fitting and welding a disc that will become the bottom plate to the bottom of a cylindrical body with the part that will become the spout bulging out. The bottom is formed into a cylindrical shape and is made of metal such as stainless steel or aluminum. A pedestal 6 is attached to the bottom surface of the bottom plate, and the pedestal 6 is attached to the bottom 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.

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 protrusion 65 protruding from the lower surface of the bottom plate of the container 5, and also has several countersink parts 6 with internal threads cut locally.
7 is equipped with a fitting hole 68 in the center, and the pedestal 6
The pedestal 6, which is positioned by fitting the central protrusion 61 into the fitting hole 68, is fixed to the container 5 via the bottom plate fitting 60 by screws 69 screwed into the countersink part 67. .

The handle 7 is composed of a main body 70 and a cover 71, both of which are made of synthetic resin, and includes a pair of upper and lower handle fittings 76.
．． It is attached to the container 5 via 76. The base end of each handle fitting 76 is connected to the container 5! +'? '? In addition to being well-fixed, it is equipped with a countersink part 77 with a female thread cut on the tip surface, and the main body part 70
is attached to the main body part 70 by screws 78, and the cover 71 is attached to the main body part 70 by 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 the opening between this space and the outer peripheral surface of the container 5 is made by the main body part 70. A partition 9 piece 72 integrally formed with the handle 70 is positioned to prevent fingers swinging the handle 7 from coming into contact with the outer circumferential surface of the container 5, and the partition piece 72 itself also touches the outer circumferential surface of the container 5. Because it is designed to leave an insulating space 73 in between without touching the handle 7, even when there is hot oil in the container 5, there is a risk of burns on the fingers of the person holding the handle 7, or a hot feeling. It is made so that there is no possibility of Furthermore, the upper end of this handle 7 is connected to an upper handle fitting 76.
Further above, a space 75 which is open to one side and both sides is formed between the outer circumferential surface of the container 5 and a knob 14 of the first filter body 1, which will be described later, is inserted into this space 75. It is made so that it can be stored.

Next, the structure of the container 5 will be explained. This container 5 has a cylindrical shape with a bottom and six spout portions formed as bulges 54.A circular repair made of metal such as stainless steel or aluminum is installed along the inner circumferential surface of the upper part of the container 5. A melting body 50 is fixed thereto, and an oil filler fitting 55 is detachably inserted into the pouring spout. The ring body 50 includes annular projections 51 and 52 in two stages, upper and lower, and a plurality of projections 5 located above the annular projections 51 and 52.
The upper annular projection 51 has a trapezoidal cross section, the lower annular projection 52 has a semicircular cross section, and the inside of the container 5 has a trapezoidal cross section. The upper space is divided into a portion surrounded by the ring body 50 and having a circular horizontal cross section, and a spout portion formed as a bulge 54. Incidentally, the upper end of the container 5 and the upper end of the ring body 50 have the portions facing the space 75 of the handle 7 cut away.

The bulging part 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. The oil filler fitting 55, which is inserted until its lower end abuts against a protrusion 56 protruding from the inner surface of the bulging portion 54, has a semicircular horizontal cross section, and the curvature of the horizontal cross section increases upwardly. When inserted into the spout, it protrudes above the upper end of the bulge 54 cut off as described above, and a gap 57 is formed on the inner surface of the bulge 54. It is something that gives rise to

A lid 4 that closes the upper end opening of the container 5 formed as described above.
It is composed of two parts: a main lid 40 and an oil filler lid 41.

The main fi, 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 above-mentioned protrusion in the ring body 50 is inserted into the ring body 50 and rotated. A plurality of engagement grooves 43 that engage with the portion 53 are formed on the outer circumferential surface, and a pair of semicircular four sections that are deeper at the center side are provided at intervals on the - side. It is provided with a knob 44 formed between both recesses, and further provided with a recess 45 on one end side of the knob 44 on the -1- plane.

As shown in FIGS. 5 and 6, the oil filler lid 41 has a pair of kiosks that project laterally from the outer surface of the oil filler lid 41.
ll 47 is positioned within the four parts 48 formed on the side walls of the recess 45 of the upper lid 40, and one end of a spring 46 made of stainless steel or the like arranged in the recess 45 of the upper lid 40 is engaged with the lower surface of the oil filler lid 41. The oil filler lid 4
When 1 is pushed down, the spout is closed to prevent dirt, dust, insects, etc. from entering, and when it is raised, the spout is opened. Then, pouring by raising and lowering the oil filler lid 41 [1
The opening/closing of the oil filling lid 41 is performed by reversing the biasing direction of the spring/I6, which is bent in the middle, so that the oil filling lid 41 is biased in both directions at the midpoint of the tilting angle range.

In other words, when the spout is closed and when the spout is closed,
Both positions are maintained by a spring 46. Moreover, this operation is caused by 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 four parts 48. It has a click effect due to the touch of the button.

When attaching and detaching the upper lid 40, since the oil filling lid 41 provided on the upper lid 40 is shaped to cover the pouring spout, the protrusion 53 and the engagement groove 43 must be engaged or disengaged. The operation of rotating the upper lid 40 for
1 and the spout must be left open. Due to the presence of the seal ring 42 provided on the upper lid 40, even if the upper lid 40 is tipped over while attached to the container 5, there is almost no oil leakage.Furthermore, the seal ring 42 has a V-shaped cross section. Since it is not used, the resistance to rotation for attaching and detaching the main cover 40 is small, and although the seal ring 42 is provided,
It can be easily attached and detached, and a ring body 50 is located on the spout side of the upper lid 40 to prevent oil from coming into contact with the upper lid 40, making it sanitary.

Now, three types of filter bodies 1 + 2 + 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 to 40 meshes of wire mesh 11 are arranged, 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, and is placed inside a cylindrical case 8. and is housed in the container 5. The remaining filter body 3 is constructed as a cartridge with activated carbon 33 as the main part for filtration, and is made of a metal such as aluminum and has a cylindrical shape with a bottom and has a number of holes drilled in the bottom surface. Inside the oil purification case 30,
” 1 The lower part is a non-woven fabric filter 31 made of polyester etc.
It is formed by storing activated carbon 33 in a sandwiched state at 32 degrees, and fixing a perforated upper plate 34 such as punched metal to the upper opening of the oil purifying case 30 by caulking, and installing it at the lower end opening of the case 8. Container 5
It is stored inside. Activated carbon 33 is 1. Due to the presence of the non-woven filters 31, 32, there is no possibility of spillage.

The case 8 is housed in the container 5 by locking the upper end of the bundle on the annular protrusion 51 of the ring body 50, and has an arc-shaped hanger 81 attached to the upper part and a lower part of the case 8. A small-diameter cylindrical portion 83 is formed through a tapered surface 82, and an annular packing 84 having oil resistance is installed on the inner peripheral surface of this small-diameter cylindrical portion 83. The IML overbody rod formed as a cartridge is housed in the case 8 from above and is disposed in the small diameter cylindrical part 83 by bringing the 7-run part of the upper end of the oil purifying case 30 into contact with the packing 84. , and the paper filter 2 is case 8.
It is arranged in the upper part having a large diameter with the lower end peripheral edge resting on the tapered surface 82 of. 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, respectively.

The filter bodies 2 and 3 are attached to a case 8 which is attached to a container 5.
the annular protrusion 51 of the ring body 50 as described above.
By supporting the case 8, the container 5 is installed inside the container 5. Further, the filter body 1 is housed in the container 5 with the upper end 7 flange portion of the case 10 engaged with the two edges of the case 8, and the wire mesh handle 13 is attached to the container 5 and the ring body. The knob 14 is positioned in the space 75 of the handle 7 by being passed through the notch in the handle 7 . Furthermore, at this time, the case 10 of the first filter body 1 enters inside the second filter body 2 - housed inside the case 8 . ) The rod body 2 of tIS2 which is a paper filter
This prevents the person from collapsing.

Now, in the oil purifier constructed in this way, the oil used for tempura etc. is poured with the lid 4 removed. At this time, the oil is first poured into the first ti, which is a wire mesh.
After relatively coarse impurities such as sludge are removed by the filter rod, it passes through the second filter 2. After fine impurities in the form of mud are removed by the filter body 2, which is a wk filter, the gas is reliably passed through the third filter body 3 due to the presence of the packing 84. In addition, the inner diameter of the filter body 2 is made larger than the diameters of the filter bodies 1 and 3,
As mentioned above, the filter body 2 has a large number of folds to increase its surface area, so it is convenient to pour in a large amount of oil at once, and it also takes a short time. Furthermore, 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, so that the oil passes through the filter body 2 reliably. Furthermore, since the tapered surface 82 is provided on the case 8 and the gasket 84 is located below the tapered surface 82, oil will not stay inside the tennis ball 8.

The oil that has reached the filter body 3 is diffused as it passes through the upper plate 34 and the nonwoven fabric filter 31, and the M of the activated carbon 33
As it passes through, coloring components and odors are adsorbed and removed.

Further, due to the presence of the non-woven filters 31 and 32, the activated carbon 33 will not be mixed into the purified oil. In this way, each 1st and 2nd day off. The oil that has passed through -3 is stored in an oil storage tank located at the lower part of the container 5. A series of oil purifications to the north are possible even when the lid 4 is closed because air is circulated to the outside through a 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, when the container 5 is tilted, the oil passes through the passage between the bulging portion 54 and the case 8 and flows out from the spout. At this time, even if the container 5 is tilted greatly, the seal ring 42 of the upper lid 40 is in pressure contact with the inner surface of the ring body 50, so there is a possibility that the entire lid 4 or the WL over-rod body 1 will come off. Without any problem, the oil leaks into each filter 1,
Even if the oil flows backward through the pipes 2 and 3, the presence of the seal ring 42 prevents oil from overflowing from places other than the spout.

On the other hand, the oil flowing out from the spout 7 is guided to the oil spout 55 and exits by tt. This oil filler fitting 55 is provided to prevent oil from dripping from the spout, and even if oil drips on the outer surface of the oil filler fitting 55, this oil will be absorbed by the oil filler fitting 55. Gap 5 between the inner surface of the bulging portion 54
7, and 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 onto the outer surface of the container 5.

As described in "Advantageous Effects 1 and 2" of the present invention, the lid is composed of a main mold that closes the opening of the container and an oil filler lid that closes the pouring spout, and when pouring out oil, You only have to open the small oil filler lid, and even if you accidentally tip the container over,
The opening is closed by the main mold, and the main mold here does not need to be easily removed in order to facilitate the operation of pouring out the oil, thereby suppressing oil leakage. Furthermore, since the oil filler lid and the main mold are integrally formed, the lid can be easily handled when pouring oil into the container.
