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] Some oil purifiers use activated carbon in addition to wire mesh as a filter to remove not only fried residue but also coloring, odor, and the like. In this case, activated carbon deteriorates quickly, and if deteriorated activated carbon is continued to be used, it will not be possible to effectively purify the oil, so it is necessary to replace the activated carbon when the number of times it has been used exceeds a certain level. By the way, there is a device that is capable of displaying the number of times of use, as disclosed in Japanese Utility Model Application Publication No. 57-111308.

However, since the display device used here is manually operated each time it is used, it is troublesome to operate, and if you forget to operate it, you will not know the exact time to replace it. .

[Objective of the Invention 1 The present invention has been made in view of the above points, and its object is to provide an oil purifier that can reliably indicate when to replace a filter body made of activated carbon. be.

[Disclosure of the Invention] Accordingly, the present invention includes a filter body made of a wire mesh and a filter body made of activated carbon, and a display unit that counts the number of times the mesh is attached and detached and displays the counted value. The main idea is that the counter is installed on the outside, and each time the oil passes through, the filter body made of wire mesh is removed and the accumulated fried crumbs are discarded. By a counter that counts the attachment and detachment of the body,
It is characterized by displaying an indication of when to replace the IT passage body made of activated carbon.

The present invention will be described in detail below based on the illustrated embodiment. This oil purifier has three types of IT over-rods in the upper part of the container 5, which has a cylindrical shape with a bottom and has a lid 4 attached to the upper opening. 12.3 is installed. 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 outside. It has a cylindrical bottom shape and is made of metal such as stainless steel or aluminum. A pedestal 6 is attached to the bottom of the bottom plate, and the circumferential surface!
A handle 7 is provided on the opposite side of the portion where the bulging portion 54 serving as the pouring spout is formed.

A pedestal 6 made of synthetic resin and attached to the lower surface of the bottom plate of the container 5 via a bottom plate metal fitting 60
is a pair of opposing hooks 63.63 provided on its lower surface.
The support legs 62 are held slidably in the radial direction by the support legs 62. By spreading out the plurality of support legs 62 as shown in Fig.
As shown in the figure, by storing the support legs 62 on the lower surface of the pedestal 6, the storage space can be kept small. Since stoppers 62a and 62b that engage with the end faces of the seven hooks 63 are provided at both ends of the support leg 62 in the sliding direction, the support foot 62 will not be pulled out from the seven hooks 63. The bottom plate metal 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 has several countersink parts 6 with internal threads cut on the periphery.
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 attached to the container 5 through the bottom plate metal fitting 60 by screws 69 screwed into the counter sink part 67.
is fixed to.

The handle 7 is composed of a main body 7° and a cover 71, both of which are made of synthetic resin, and a pair of upper and lower handle fittings 76.
．． It is attached to the container 5 via 76. Each handle metal fitting 76 whose base end is welded and fixed to the container 5 is equipped with a countersink part 77 with a female thread cut on the distal end surface, and the main body part 70 is connected to the handle metal fitting 76 by a fitting 8, and the cover 71 is attached to the main body portion 7o with screws 79. Here, the main body part 7o forms a space 74 between the pair of upper and lower handle fittings 76, 76, into which fingers can be inserted, and this space and the container 5
A partition piece 72 integrally formed with the main body 7o is positioned between the outer peripheral surface of the container 5 and the partition piece 72 to prevent fingers gripping the handle 7 from coming into contact with the outer peripheral surface of the container 5. Since the piece 72 itself does not come into contact with the outer circumferential surface of the container 5 and leaves a heat insulating space 73 between them, even when there is hot oil in the container 5, there is no risk of burns to the fingers holding the handle 7. Further, the upper end of the handle 7 is located further above the upper handle fitting 76, and extends upwardly and on both sides of the outer circumferential surface of the container 5. It is said that it forms a space 75 open to the
A knob 14 of the first filter body 1, which will be described later, can be accommodated in this space 75.

A counter 9 is housed in the handle 7 at the same position as the upper handle fitting 76.

The counter 9 has a counting rod 91 and a reset rod 92 protruding upward, as shown in FIG. Claw foot 93a and heart-shaped cam 93b
is supported by a pongee 94, and a spring 95
When the counting rod 91 is pushed down against the
In order for 6 to advance the number wheel 93 together with the claw cage 93a,
The display numbers appearing in the display window 90 facing the upper side of the handle 7 are replaced. When the reset rod 92 is pressed against the return spring 97, as shown in FIG.
The heart-shaped cam 93b is driven, and the eight-shaped cam 93b
rotates until the minimum radius position touches the reset rod 92. This resets the number displayed on the display window 90 to 0.
This is a spring for preventing reverse rotation of a. Also, this counter 9
The case 100 includes a top plate 101 that is locked by an elastic hook, and a bottom plate 102 that is fixed by ultrasonic welding or the like.
1 and the reset rod 92 are prevented from being removed.

By the way, in the space 75 above the handle 7 from which the counting rod 91 and the reset rod 92 of the counter 9 protrude,
As mentioned above, the knob 14 in the filter body 1 of @1 is accommodated. This knob 14 is designed to press the counting rod 91.

Each time the knob 14 is placed in the space 75, the counting rod 91
When pressed, the counter 9 increases the displayed number. In order to prevent the knob 14 from pressing the reset rod 92, the portion of the knob 14 located above the reset rod 92 is cut out.

Now, the container 5, which has a cylindrical shape with a bottom and whose spout is formed as a bulging part 54, has a circular ring body made of metal such as stainless steel or aluminum along its upper inner circumferential surface. 50 is fixed,
A lubricant cap 55 is also removably inserted into the spout. As shown in FIGS. 1 and 5, the ring body 50 includes annular protrusions 51 and 52 in two stages, upper and lower, and a plurality of protrusions 53 located above these annular protrusions 51 and 52. is made to protrude inward, and the upper space inside the container 5 is divided into a portion with a circular horizontal cross section surrounded by the ring body 50 and a spout portion formed as a bulging portion 54. There is. Note that the upper end of the ring body 50 has a portion facing the space 75 of the handle 7 cut out.

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. A lubricating cap 55 is inserted therein as described above. This lubricating cap 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 becomes larger upwardly. When it is inserted into the spout, it protrudes above the upper end of the bulge 54 cut off as described above, and there is a space ll51 between it and the inner surface of the bulge 54. [57].

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 pipe 40 and an oil filling lid 41.

The main seal 40 has a seal ring 42 attached to the outer circumferential surface of the ring body 50, which is in contact with the inner circumferential surface of the ring body 50, and is attached to the protrusion 53 on the ring body 50 by fitting the seal ring 42 into the ring body 50 and rotating the seal ring 42. A plurality of engaging grooves 43 are formed on the outer peripheral surface, and a pair of semicircular recesses are provided at intervals on the upper surface, so that a knob portion 44 is formed between the two recesses. Furthermore, a recess 45 is provided at one end side of the knob portion 44 on the upper surface.

One end of the oil filler lid 41 is pivotally supported by the main pipe 40, and when it is folded down, the spout is closed to prevent dirt, dust, insects, etc. from entering, and when it is raised, the spout is opened. Here, the opening and closing of the pouring spout by raising and lowering the lubricant 1i41 is performed by a spring 46 disposed in the recess 45 of the main pipe 40.
As a result, the oil filling lid 41 is biased in both directions at the middle of the tilting angle range. In other words, both the state where the spout is closed and the state where the spout is open are the spring 4
6.

Three types of filter bodies 1, 2.3 are arranged in the container 5. The filter body 1 has three types of filter bodies 1 and 2.
It is constructed by disposing wire mesh 11 of 0 to 40 meshes, 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 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. Inside 30, there are non-woven filters 31°32 made of polyester etc. on the top and bottom.
Activated carbon 33 is housed in the sandwiched state, and a perforated upper plate 34 such as punched metal is fixed to the upper opening of the oil purifying case 30 by caulking, and is installed in the lower opening of the case 8. It is stored in the container 5 in a closed state.

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, and has an arc-shaped hanger 81 attached to the upper part.
A small diameter cylindrical portion 83 is formed in the lower part, and this small diameter cylindrical portion 83
An annular packing 84 is installed on the inner peripheral surface. The filter body 3 as a cartridge is placed in the case 8 from above, and the 7-run part at the upper end of the oil purifying case 30 is brought into contact with the packing 84, so that the filter body 3 is arranged in the small diameter cylindrical part 83.
Further, the filter body 2, which is a paper filter, is placed in the upper part having a large diameter, with the lower end peripheral edge placed on the lower part of the case 8.

The filter body 2.3 is attached to the case 8 which is attached to the container 5.
It is installed in the container 5 by putting it inside.

Further, the filter body 1 is housed in the container 5 with the upper end 7 run portion of the case 10 locked to the upper edge of the case 8, and the wire mesh handle 13 is attached to the notch end of the container 5 and the ring body 50. The knob 14 is positioned in the space 75 of the handle 7 by being passed through. Furthermore, at this time, the case 10 of the filter body 1 prevents the second filter body 2, which is a class 0 filter, from falling down, which enters the inside of the filter body 2 housed inside the case 8. .

Now, in the oil purifier configured in this way, 1i4
The oil used for tempura, etc. is poured into the first trough, which is a wire mesh, with the trough removed.
t3F! After relatively coarse impurities such as fried crumbs are removed by the i body 1, it passes through the second filter body 2, and fine impurities like sludge are removed by the filter body 2, which is a paper filter. Passes through body 3. and filter body 3
The oil is diffused when passing through the upper plate 34 and the nonwoven filter 31, and coloring components, odors, etc. are adsorbed and removed while passing through the layer of activated carbon 33. 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.

To throw away impurities such as fried crumbs that have accumulated on the filter body 1 when filtering oil, remove the lid 4, pinch the knob 14, and take out the filter body 1. And after discarding the impurities,
When the filter body 1 is set again and the knob 14 is housed in the space 75, the counting rod 91 is driven by the counter 9's pin 14, so that the counted up number is displayed on the display window 90.

If the number of uses indicated by counter 9 remains at the predetermined number of times,
-fr If the adsorption capacity of the activated carbon 33 of the filter body 3 disappears or decreases due to contamination, these filter bodies 2 and 3 should be discarded together. and replace it with a new one. For this replacement, the entire case 8 can be taken out. The filter body 3 is replaced with the cartridge. Also, at this time of replacement, the reset rod 92 is pressed to reset the counter 9.

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 rod 4. When the oil filler lid 41 is opened, the oil filler lid 41 is held in that state by the spring 46. The oil flowing out from the spout is guided by the oil filler fitting 55 and exits. At this time, even if oil drips along the outer surface of the oil filler fitting 55, this oil enters the gap 57 between the oil filler fitting 55 and the inner surface of the bulge 54, and then between the lower end of the oil filler fitting A55 and the inner surface of the bulge 54. It returns to the oil storage tank through a small gap between the oil and the protrusion 56. This prevents oil from dripping onto the outer surface of the container 5.

[Effects of the Invention] As described above, in the present invention, the number of attachment and detachment of the filter body made of wire mesh, which is attached and detached to discard fried crumbs after each use, is counted using a counter. There is no need for the user to perform any operations to record the number of uses, and the number of uses is automatically recorded.
Therefore, the filter body composed of activated carbon that has lost its effectiveness is
This eliminates the possibility of accidentally using it over and over again.
