Description

[Detailed Description of the Invention] [Technical Field 1] The present invention relates to a purifier equipped with a wire mesh for filtering contaminated edible oil such as tempura oil that has been used or is in the process of being used and removes fried residue. Regarding oil appliances.

[Background Art] Oil purifiers that purify tempura oil and the like are used many times on a daily basis, and are used in kitchens, which are relatively small spaces with a variety of equipment, and are likely to cause burns. Since the device will be handling high-temperature oil, it needs to be easy to hold, easy to use, and highly safe. However, the conventional oil purifier was developed in 1974. -2
When trying to remove a wire mesh (strainer mesh) that is placed inside a container and is used for filtering purposes other than frying, as shown in Publication No. Therefore, it is not only inconvenient to remove the oil, but there is a risk of burns if you try to remove it immediately after purifying the high-temperature oil, so there are many problems in terms of usability and safety. I had this problem.

[Objective of the Invention] The present invention was developed in consideration of these points, and its object is to provide an oil purifier that is not only easy to use but also highly safe.

Therefore, the present invention provides a gold #A stopper for filtration disposed inside the container. fl+'7+mma, container. The container is characterized by having a jut protruding from the side and a grip on the outer surface of the container that is vertically opposite to this knob, which makes it easy to carry out tasks such as frying and disposal by grasping the handle provided on the wire mesh. In addition to improving usability and safety, the handle is 1"& up and down.
0t6′m&″″・? 1" so that it does not get in the way.

The present invention will be described in detail below based on the illustrated embodiment. This oil purifier has three types of filter bodies 1, 2.3 is arranged, and first we will explain the container 5.
This is a cylinder with a bottom formed by press-fitting and welding a disc that will serve as the bottom plate to the bottom of a cylinder whose spout is bulged out.It is made of metal such as stainless steel or aluminum. The pedestal 6 is attached to the bottom surface of the bottom plate.
A handle 7 is attached to the opposite side of the circumferential surface from the portion where the bulging portion 54 serving as the pouring spout is formed.

The pedestal 6' made of synthetic resin is a container 5.
is attached to the lower surface of the bottom plate of the base plate 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 67 with female threads cut on the periphery in the center. Department.

It is equipped with a fitting hole 68 in the center of the base 6, and
The pedestal 6 is positioned and determined by the booklet 1 that is fitted into the fitting hole 68, and is fixed to the container 5 via the bottom plate fitting 60 by screws 69 screwed into the counter sink portion 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. Each metal handle 76 has its base end welded to the container 5 1i! The main body part 70 is attached to the handle fitting 76 by screws 78, and the cover 71 is attached to the main body part 70 by screws 79. It is attached to. Here, the main body part 70 forms a space 74 between the upper and lower handle fittings 76 and '76, into which fingers can be inserted, and between this space and the outer peripheral surface of the container 5. A partition piece 72 formed integrally with the main body part 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 also protects the container 5. Open insulation space 7 without contacting the outer peripheral surface
3, so that even when there is hot oil in the container 5, the hands and fingers holding the handle 7 will not get burned or feel hot. .

Further, at the upper end of the handle 7, a recess is formed above the upper handle fitting 76 to form a space 75 that is open upward and to both sides in the darkness with the outer peripheral surface of the container 5. The first Wi and the knob 14 of the overbody 1, which will be described later, 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 made of metal such as stainless steel or aluminum along its upper inner circumferential surface. A body 50 is fixed, and a tool 55 is removably inserted into the spout. The ring body 50 has two upper and lower annular protrusions '51 and 52 and a plurality of protrusions 5g located above these annular protrusions 51 and 52 that protrude inward. , the upper annular protrusion 51 has a trapezoidal cross section, and the lower annular protrusion 5'2
has a semicircular cross section, and a ring body 50 surrounds one space in the container 5 with a circular horizontal cross section and a spout portion formed as a bulge 54. Note that 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 point slightly below the center of the container 5 in the downward direction to one end of the container 5, and the upper end is cut off diagonally. Also, the oil filler fitting 55 is inserted into the second part as described above. A protrusion 5 protruding from the inner surface of the bulge 54
This oil filler fitting 55, which is inserted until the lower end abuts on the oil filler hole C), has a semicircular horizontal cross section, and the curvature of the horizontal cross section becomes larger at the top. 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.

A 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 filler lid 41.

The main lid 40 has a seal ring 42 attached to its outer circumferential surface which is in contact with the inner circumferential surface of the ring body 50, and the above-mentioned protrusion in the ring body 50 is formed by fitting the seal ring 42 into the ring body 50, turning it, and manipulating it. A plurality of engagement grooves 43 are formed on the outer circumferential surface to engage with the portion 53, and a pair of semicircular four portions, which are deeper at the center, are provided on the upper surface at intervals, thereby forming both recesses. The knob 44 formed between the two is turned off, and a recess 45 is provided at one end of the knob 44 on the top surface.

The oil filler lid 41 has one end pivoted to the main indigo 40, and when it is opened, the spout is closed and dirt, dust, etc.
It prevents insects from entering, and the spout opens when you wake it up. Here, the opening and closing of the spout by raising and lowering the oil filling lid 41 is performed using a spring 4 disposed in a recess 45 of the main lid 40.
6, the middle of the tilting angle range of the oil filler lid 41 is reached as a border.
It is biased in both directions. In other words, both the state in which the spout is closed and the state in which the spout is open are held by the spring 4G.

Now, three types of filter bodies 1, 2, and 3 are arranged in the container 5. The filter body 1 is located at the bottom opening of an inverted semiconical 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. In addition, knob 1
4 is made of aluminum, resin, heat-resistant rubber, or the like.

lf The rod body 2 is formed by molding paper into a bottomed cylindrical shape, and in particular has many vertical folds formed on the circumferential surface, and is arranged in a cylindrical case 8. and stored in the container 5. The remaining filter body 3 contains activated carbon 33.
The oil purifying case 30 is configured as a cartridge with a main component for cleaning, and is made of a metal such as aluminum and has a cylindrical shape with a bottom and has many holes in the bottom.
Activated carbon 33 is stored with the upper and lower sides sandwiched between non-woven fabric filters 31 and 32 made of polyester, etc., and
It is formed by caulking and fixing a perforated top plate 34 such as punched metal to the top opening of the oil purification case 30,
It is housed in the container 5 while being installed at the lower end opening of the case 8 . The activated carbon 33 is the nonwoven fabric filter 3
Due to the presence of 1.3'2, there will be no leakage.

The case 8 is housed in the container 5 by having two end edges locked onto a portion 51 of the annular beam 8 in the ring body 50, and an arc-shaped hanger 81 is attached to the top. , a small diameter section 83 is provided at the bottom via a tapered surface 82.
is formed, and an annular packing 84 having heavy oil properties is provided on the inner circumferential surface of this small diameter cylindrical portion 83. The filter body 3, which is formed as a cartridge), is inserted into the case 8 from above.
By bringing the upper and lower seven rings of the oil purifying case 30 into contact with the gasket 84, the filter body 2, which is a paper filter, is disposed within the small diameter cylindrical portion 83. With the lower end periphery resting on the tapered surface 82, it is placed within the two large-diameter parts. 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 which is attached to a container 5.
the annular protrusion 5 of the ring body 50 as described above]
(Thus, by supporting the case 8, the filter body 1 is installed in the container 5.
The run-off part is stored in the container 5 with the -J edge of the case 8 locked, and the wire mesh handle 13 is attached to the container 5.
The knob 14 is positioned in the space 75 of the handle 7 by passing through the notch in the ring body 50. Furthermore, at this time, the case 10 in the ptSi filter body 1 is
It enters the inside of the second filter body 2 housed inside the case 8. This prevents the second filter body 2, which is a paper filter, from falling down.

Now, in the oil purifier constructed in this way, the oil used for tempura, etc. is poured in with the lid 4 removed, but at this time, the oil is first poured into the first ll
! After comparatively coarse impurities such as fried crumbs are removed by the filter body 1, it passes through the second filter body 2. After fine slimy impurities are removed by the filter body 2, which is a paper filter, the gas is reliably passed through the third filter body 3 due to the presence of the packing 84. 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 all at once, but the filtration time is short.
Furthermore, even when a large amount of oil is poured at once, the oil passes through the U rod 2 reliably because the filter body 2 is prevented from falling over by the case 10 in the waste body 1. Furthermore, since the tapered surface 82 is provided on the case 8 and the gasket 84 is located below the tapered surface 82, the oil flows into the case 8.
It will not stay inside.

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 coloring components, odors, etc. are adsorbed and removed while passing through the layer of activated carbon 33.

Further, due to the presence of the non-kelp filters 31 and 32, the activated carbon 33 will not be mixed into the purified oil. The oil that has passed through each of the filter bodies 1, 2.3 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. Even if the container 5 is tilted greatly, the seal ring 42 of the first lid 40 is in pressure contact with the inner surface of the ring body 50, so the entire lid 4 or the filter body 1 will not come off, and the oil is each filter body 1
, 2.3, 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 is forced into the oil filler fitting 55 and exits. This oil filler fitting 55 is
This is provided to prevent oil from dripping from the spout, and even if oil drips on the outer surface of the spout 55,
This oil enters the open gap 57 between the oil filler fitting 55 and the inner surface of the bulge 54, and then enters 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. Return to. This prevents oil from dripping onto the outer surface of the container 5. ' To discard the impurities accumulated in the filter body 1, remove the lid 4, pinch the knob 14, and take out the filter body 1. Even if this work is performed immediately after purifying the hot oil, the presence of the knob 14 will not cause burns and will not stain the hands. Further, although such a knob 14 is provided, the knob 14 is normally located at the same position as the handle 7 in the circumferential direction of the container 5, and here it is located between the handle 7 and the container 5. space 75
Since the knob 14 is positioned and the width of the knob 14 is smaller than the width of the handle 7,
Even if the knob 14 gets in the way, if you move the knob 14 carelessly, or if you topple this oil purifier, external force will be applied to the knob 14 and the lid 4 will be removed. There is no possibility that the knob 14 will be bent. Furthermore, since the wire mesh handle 13 is passed through the notch in the container 5 and the ring body 50 so that the knob 1 is positioned in the space 75, the filter body 1 may be inadvertently rotated and the position of the knob 14 may be changed. In addition, if the knob 14 is not located in the space 75, the filter body 1 will not fit properly in the container 5.
Also, ¥i and 4 cannot be closed.

Not only the used filter body 2 is thrown away and replaced with a new one, but also the filter body 3, which has lost its adsorption capacity or has decreased its adsorption capacity, is also thrown away along with its cartridge and replaced with a new one. However, when replacing these filter bodies 2 and 3, case 8
All you have to do is take it out, and since you can use the handle 81 provided at one end of the case 8 to take it out, you can do it without getting your hands dirty. By using the case 8 to arrange the filter bodies 2 and 3 to be discarded, the replacement work is facilitated.

In addition, the oil purifier here has a temperature indicating material 9 on the outer surface of the lower part of the container 5, that is, on the outer surface of the part corresponding to the oil storage tank.
is attached.

For example, when the temperature is below 70°C, this temperature indicator material exhibits a specific monochromatic color as shown in Figure 5(a).
If the temperature rises above °C, as shown in Figure 5 (I), some parts of the fish will change color and the entire fish will become hotter.
It also indicates that the container 5 will return to its original state when the temperature drops, and will instruct the user whether or not the temperature of the container 5 has reached a dangerous temperature that could cause burns. Do not touch the container 5 (This means that the user can recognize whether the container 5 is at a dangerous temperature or not, and this reduces the risk of getting burned by touching the hot container 5.) That's why.

[Effects of the Invention] As described above, in the present invention, the wire mesh is provided with a knob so that the wire mesh can be removed from the container by holding the knob, so it is easy to use and does not get your hands dirty. Second, there is less risk of burns from touching the hot wire mesh, and the knobs here are vertically opposed to the handle on the outside of the container. Therefore, the knobs do not get in the way of handling.
