This frying dish is made through a frying device, which is provided with a heater as a heating means inside a frying container filled with oil, that is, edible oil, and the heat generated by the heater directly heats the oil filled in the frying container. The heated oil will fry various foods such as chicken, french fries, donuts, and croquettes.

However, there is a problem of accelerating the rancidity of the oil (edible oil) as the residues such as crumbs of the finely sized frying clothes separated from the fried dishes by the high temperature of the heater are carbonized.

In addition, when a heater is used as a single heating source, the cooking time is long and the cooking object is not cooked evenly.

In addition, various types of lifting devices have been disclosed to improve this because the user has to lift the frying container one by one according to the cooking time. there was.

Furthermore, in the case of the conventional fryer, since the heater, which is the heating source, is maintained in a fixed state, there is a disadvantage that it is very inconvenient to use when cleaning for maintenance such as washing after use.

The fryer according to the present invention includes a main body 100 provided with a control panel 110 on the front side, as illustrated in FIGS. 1 to 7 .

At this time, the main body 100 is provided with a caster on the lower surface to be movable.

In addition, a frying tank 200 is provided in the main body 100 .

The frying tank 200 has an open upper portion, an inner wall surface is formed of stainless steel, and is heated while being filled with oil to fry the processed material.

In addition, a drain from which oil can be removed is provided on the bottom surface of the frying tank 200, but is omitted from the illustration.

In addition, a recess 210 (refer to FIG. 3) is formed on the rear surface of the frying tank 200 of the main body 100, and a pair of left and right elbow-type support tubes 310 on the rear upper surface of the main body 100. It further includes a junction box 300 that is rotatably hinged by the junction box.

In addition, the heating element 400 is connected and fixed to the junction box 300 , and an appropriate current is applied through the junction box 300 to generate heat.

And, the heating element 400 is disposed inside the frying tank 200, and since the junction box 300 has a rotatable structure, if you want to clean the frying tank 200, the junction box 300 as shown in the example of FIG. ) is rotated by 90 °, so that the heating element 400 can be taken out of the frying tank 200 .

In addition, in order to facilitate rotation of the junction box 300, a rotation handle 320 is installed through the elbow-type support pipe 310 on one side, and the end of the rotation handle 320 is the junction box 310. The junction box 310 may be easily rotated by holding and lifting the rotation handle 320 by fixing it to the junction box 310 .

On the other hand, the lifting unit (UNT) may be arranged and fixed on the upper portion of the junction box 300 .

The lifting unit UNT includes a box-shaped lifting housing 500, and both lower ends of the lifting housing 500 are extended pieces 510 (FIG. 4) so that the junction box 300 has a rotatable space. , 5) is extended, and the lower end of the extension piece 510 is fixed to the rear upper surface of the main body 100 , and slits 520 are vertically formed on both sides of the lower end surface of the lifting housing 500 by a certain length. The slit 520 has a hook 530 that can be lifted along it, and a hook 540 is hooked on the hook 530 so that a tray 600 containing a fried object can be hung.

In addition, a dividing wall 502 is horizontally fixed inside the lifting housing 500 as shown in FIGS. 4 and 5 , and a pair of guides is provided between the dividing wall 502 and the bottom surface 504 . The rod 550 is vertically fixed.

In addition, an annular slider 552 is fitted to the guide rod 550, and an elevating plate 560 is fixed to the upper end of the slider 552, and at the same time, a hook penetrating the slit 520 is provided on the circumferential surface ( One end of the 530 is fixed integrally, and the lower end of the actuating rod 570 penetrating the dividing wall 502 is fixed to the center of the upper surface of the lifting plate 560, and the working rod 570 is the dividing wall. (502) is installed to be retractable in the lifting cylinder 580 installed on the upper part.

In addition, the elevating cylinder 580 is electrically connected to the control panel 110 and configured to be driven and controlled. For example, when the oil in the frying tank 200 starts to be heated and reaches a set time, the control panel 110 ) can be configured to stop the frying operation by raising the tray 600 while the lifting cylinder 580 moves upward according to the control signal.

In this way, there is no need for an operator to lift the frying water individually, and when the frying is completed, it automatically rises and goes out of the oil.

Here, it is only shown that the rear surface of the lifting housing 500 is opened, and in fact, it is natural that the rear surface of the lifting housing 500 should be sealed by the back cover.

On the other hand, the lifting unit (UNT) may be configured to be detachable. This can be changed so that it can be used according to the installation location by diversifying the size of the lifting unit (UNT) or when the lifting unit (UNT) is not required due to the limitation of the installation space.

To this end, the insertion end 512 is further protruded from the lower end of the extension piece 510 as in (a) of FIG. 8 , and an assembly hole 514 is formed through the insertion end 512 .

In addition, a fixing groove 102 into which the insertion end 512 is fitted is formed on a corresponding upper surface of the main body 100 , and a bolt hole 104 is formed on the side surface of the main body 100 in which the fixing groove 102 is formed. This is formed, and in the state in which the insertion end 512 is inserted, the fixing bolt 106 is fastened through the bolt hole 104 and the assembly hole 514, so that the extension piece 510 can be easily fixed and released. There, it is possible to facilitate the removal of the lifting housing (500).

In this case, when the lifting housing 500 is detachable, since interference with the rotary handle 320 occurs, the rotary handle 320 may have a structure as shown in (b) of FIG. 8 .

According to the drawing, the rotation handle 320 is segmented into a first rod 322 and a second rod 324, and an assembly cylinder 326 having a spline formed on the inner circumferential surface is fixed to the end of the first rod 322. and splines corresponding to the splines of the assembly cylinder 326 are formed on the circumferential surface of the second rod 324 to pass through the extension piece 510 and then be installed to be fitted into the assembly cylinder 326 have.

Then, when the second rod 324 is rotated because it is spline coupled, the assembly cylinder 326 is rotated together, so that the junction box 300 can eventually be rotated.

Then, when the lifting housing 500 needs to be separated, the second rod 324 can be removed from the assembly cylinder 326, and the lifting housing 500 can be easily attached and detached without interference.

On the other hand, in the present invention, in order to guide an evacuation route in case of a fire and reduce casualties, an evacuation guide coated with a phosphorescent paint may be further configured on the front and side surfaces of the main body 100 .

In this case, the phosphorescent paint is intended to enable safe evacuation by implementing an emergency escape guideway when electricity goes out in case of fire or emergency.

For this purpose, the photoluminescent paint is a crystal using SrAl ₂ O ₄ as a mother crystal, and is a material that emits light for a long time, so that it can act as a kind of guide vessel or guide wire in a dark place or when electricity is cut off.

The photoluminescent paint according to the present invention is based on 100 parts by weight of the epoxy resin, 20 parts by weight of an amine curing agent, 20 parts by weight of blast furnace slag fine powder, 5 parts by weight of a pigment, 4.5 parts by weight of oleic acid, 10 parts by weight of CSA (Calcium Sulfoaluminate), and 4.5 parts by weight of barium carbonate. After adding and mixing parts by weight, 3.5 parts by weight of sodium phosphate, and 50 parts by weight of phosphorescent powder, the mixture is stirred and completed.

Here, the blast furnace slag powder contains calcium carbonate as a main component and is added to control the strength and voids of the paint as well as to stabilize the dimensions. In addition, the amine curing agent is preferably polyamide polyamine, and is added to promote curing of the paint. In addition, both organic and inorganic pigments can be used for the pigment, which is commonly known or can be purchased and used in the market. That is, there is no need to limit the description in particular because it is for giving a color. Furthermore, oleic acid is added to enhance adhesion and stabilization of fixation, and to maintain viscosity by promoting gelation by completely penetrating to cracks invisible on the painted surface by increasing penetrability. In addition, CSA is added to inhibit shrinkage and prevent cracking. And, barium carbonate promotes aggregation, induces the formation of a smooth surface, and does not absorb ultraviolet rays, thereby contributing to oxidation prevention and discoloration prevention. In addition, sodium phosphate forms an insoluble film on the painted surface to perform a rust prevention function.

In addition, the photoluminescent powder is pulverized to a particle size of 10 nm or less in a state in which the content of strontium aluminate (SrAl ₂ O ₄ ) is increased by heating a strontium mineral (eg, celestite or strontianite) and removing impurities, Strontium aluminate (SrAl ₂ O ₄ ) is known to be contained in about 30-50% of strontium mineral, and it is reported that the surface energy of strontium aluminate (SrAl ₂ O ₄ ) increases when the particle size is nano-sized.

Therefore, when impurities affecting the afterglow luminance are removed, the content of strontium aluminate (SrAl ₂ O ₄ ) is relatively increased by the amount of the disappeared impurities.

In particular, it is preferable to use the photoluminescent powder prepared as follows. For example, a first step of crushing a strontium mineral to a particle size of 50 mm or less, a second step of putting the crushed mineral in a heat drying furnace in the first step, and calcining at 800-1200° C. for 3 hours with reduced heat, the second step; A third step of pulverizing the reduced-calcined mineral through the steps with a nano grinder, and a fourth step of sieving and selecting only a particle size of 10 nm or less from the pulverized product pulverized through the third step; can

At this time, the reason for crushing the strontium mineral to a particle size of 50 mm or less in the first step is to increase the effect of reducing heating and calcination.

That is, it is more efficient to process small-volume objects than large-volume ones. In addition, the heating and drying furnace used in the second step is a rotary kiln, which is configured to be rotatably heated and fired with strong hot air.

This is to burn or volatilize impurities contained in strontium minerals, especially substances that inhibit afterglow luminance, while heating up to 1200°C before completely dissolving into liquid phase because strontium minerals are dissolved at 1300°C. Because. In particular, since the hot wind is blowing, the impurity removal efficiency is very excellent.

And, the nano pulverizer used in the third step is a vertical bead mill, and the raw material is put into the lower part of the container to separate the beads and the raw material in the upper separator, and the fine raw material is discharged through the outlet, and the granule The raw material is dropped into a container together with the beads, and is an equipment configured to maximize the dispersion and pulverization functions.

Here, the separator is a centrifugal gap-less type, and has an advantage in that the final particle size of the raw material can be made nano.

As a result of measuring the luminance of the photoluminescent paint prepared in this way according to the present invention, the average luminance was 35,000 mcd/m ² . At this time, a long afterglow time of about 5 hours was maintained from a value similar to the luminance (320 mcd/m ² ) defining the afterglow time to 45 mcd/m ² . Therefore, it was confirmed that the photoluminescence property was very excellent.

On the other hand, it is particularly preferable that the junction box 300 and the elbow-type support pipe 310 are made of molybdenum-chromium alloy steel to achieve heat resistance, corrosion resistance and mechanical properties.

At this time, the molybdenum-chromium alloy steel is C: 0.40-0.50 wt%, Si: 0.2-0.3 wt%, Mn: 1.0-1.5 wt%, N: 0.01 wt% or less, Sn: 0.8-1.4 wt%, Ti: 1.0- 1.5 wt%, P: 0.02 wt% or less, S: 0.01 wt% or less, Cr: 1.50-2.50 wt%, Mo: 0.90-1.40 wt%, V: 0.50-1.00 wt%, Cu: 0.20 wt% or less, Al : Use 0.02% by weight or less and the remaining Fe.

Here, C is the most important element for improving the strength of steel, and improves strength and hardness by combining with elements, particularly chromium and molybdenum, to form carbides.

However, when the content of C is less than 0.40% by weight, it is difficult to expect improvement in strength and hardness, and when heat treatment exceeds 0.50% by weight, cementite-based iron carbide increases and strength and hardness are increased, but workability is remarkably deteriorated. It is limited to the above range due to the nature of the

Si is an effective element for strength improvement due to deoxidation and solid solution strengthening. However, when it exceeds 0.3% by weight, toughness is reduced and plastic workability is impaired, and when it is added in an amount of less than 0.2% by weight, softening resistance increases during tempering, so it is preferable to limit it to the above range.

Mn is an element that suppresses ferrite formation and effectively increases hardenability by lowering the Ar3 temperature, thereby improving the strength and toughness of steel.

However, it combines with S contained in the steel to form MnS, a non-metallic inclusion, in the grains, and to improve the yield strength of carbon steel by solid-solution strengthening of ferrite. Should be.

N is to suppress the occurrence of intergranular corrosion through the reaction with Ti and should be added in an amount of 0.01 wt% or less.

At this time, the meaning of 'less than' means 'excluding 0% by weight', and the meaning of 'less than' of the content described in the present invention means excluding all '0% by weight'.

Sn should be added in an amount of at least 0.8% by weight and at most 1.4% by weight in order to secure heat resistance and corrosion resistance of condensate.

In addition, Ti is an effective element for preventing intergranular corrosion by fixing C and N, but when the Ti/(C+N) ratio is lowered, corrosion resistance is deteriorated. should be added below.

P is an element which is unavoidably contained in steel, and is an element which inhibits the toughness of steel. Therefore, the content of P should be maintained at 0.02% by weight or less, which is the unavoidably contained level.

S is an element that forms MnS inclusions in steel and inhibits the toughness of steel. Therefore, it should be maintained at 0.01% by weight or less, which is a level that S is also unavoidably contained.

Cr expands the austenite region to prevent embrittlement of steel and increases strength, hardness, and heat resistance. Therefore, the more Cr is added, the better, but if it exceeds 2.5% by weight, it should be limited because it causes tempering embrittlement, and if it is added to less than 1.5% by weight, it should be limited to the above range because low-temperature embrittlement may occur.

Mo is an element effective in improving the hardness of steel by increasing hardenability, but when it exceeds 1.40 wt%, the workability is inferior, and when it is added at less than 0.90 wt%, the carbide formation region is reduced due to ferrite destabilization and the hardness is lowered. should be limited

V is an element that easily forms carbides and is mainly present as carbides in steel. However, when added in an amount of less than 0.5 wt%, V does not increase hardness. should be limited

Cu is an element that improves the hardenability of steel and improves the strength and hardness of steel by solid solution strengthening. This Cu is dissolved in ferrite up to 0.20 wt% at room temperature to exhibit a solid solution strengthening effect, so the strength and hardness are slightly increased, but the elongation is reduced. Therefore, Cu should be added in an amount of 0.20% by weight or less.

Al is effective as a strong deoxidizer, but if the amount added is large, it weakens the steel, so it is recommended to add up to 0.02% by weight for deoxidation and denitrification.
