Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fryer for frying cooking ingredients with oil, and more particularly to a structure of an oil tank for replenishing solid oil.

[0002]

2. Description of the Related Art A technique for dividing an oil bath of a fryer into three temperatures is described in Japanese Utility Model Publication No. 40-003118.
According to this technique, an oil tank is divided into three by a partition plate and heated with different heater outputs, so that frying in three temperature zones of low temperature, medium temperature and high temperature can be provided.

According to Japanese Patent Publication No. 49-16623, an oil tank having the same temperature is divided into two parts by a vertical partition, and the lid of each oil tank is linked to each basket supporting member so that the basket supporting member moves up and down. The lid automatically opens and closes.

[0004] By such a technique, various fryers are manufactured and fried foods are cooked. Since the food material absorbs the oil in the oil tank each time it is cooked, the amount of oil in the cooking oil tank gradually decreases.

[0005]

Even when solid oil is used, it is necessary to add oil to the cooking oil tank when the oil in the cooking oil tank becomes low. However, unlike a liquid oil, it is difficult to add a solid oil little by little. Since a lump having a certain size has to be supplied, if the lump is supplied during the frying operation, the temperature of the cooking oil drops rapidly. For this reason, there was a problem that the fly operation had to be interrupted until the temperature returned to the set temperature.

[0006] Further, there is a problem that every time the oil is thrown, there is a danger of oil splashing and it is difficult for an operator to handle the oil. Furthermore, when low-temperature solid oil is injected from the upper part of the cooking tank, the oil temperature on the surface decreases, the oil on the surface drops, and instead the hot oil below rises, and the vertical convection of the oil in the cooking tank becomes active. Thus, there has been a problem that the oil that has come out on the surface is oxidized one after another, which accelerates the deterioration of the oil.

The present invention solves the above problems,
When adding solid oil during frying operation, the frying operation can be continued without lowering the temperature of the cooking oil, and the refining operation is safe,
An object of the present invention is to provide a fryer in which oil is not easily oxidized.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view of a fryer showing one embodiment of the present invention, FIG. 2 is a sectional view of a fryer showing a cooking state, FIG. 3 is a sectional view of a fryer showing a state where solid oil is charged, and FIG. It is sectional drawing of the fryer shown.

Reference numeral 1 denotes a fryer main body (hereinafter referred to as a fryer). The fryer 1 is mounted on the top surface of the refrigerator 2 so as to be maintained at a height at which a cook can easily work and to obtain foodstuffs at hand. Are located in The fryer 1 is open at the top, and is provided with an oil tank 4 having a heater 3 arranged horizontally in the stored oil. At the bottom of the oil tank 4 is provided a valve 6 for discarding oil in the oil tank 4 to an oil receiver 5. The heater 3 is integrated by a heater support 7 and is cantilevered by a heater arm 9 together with a temperature sensor 8. The heater arm 9 is connected to an arm block 10 provided at the upper end of the oil tank 4.
It rotates in the range of degrees and stops at the end point of each rotation.

A first partition plate 12 for partitioning the inside of the oil tank 4 left and right is provided in the oil tank 4 in a vertical direction, and the heater 3 is disposed in one oil tank 4 partitioned by the first partition plate 12. I have. The first partition plate 12 is formed of a heat insulating ceramic material. The partitioning method of the first partition plate 12 is detachably fixed by being sandwiched between both side walls of the oil tank 4, placed on the upper end surface of the oil tank 4, and engaged with a flange of the oil tank 4. The upper end of the first partition plate 12 protrudes from the oil level 13 stored in the oil tank 4, and the lower end extends below the heater 3,
A gap is formed between the oil tank 4 and the bottom surface.

In the oil tank 4 divided by the first partition plate 12, the cooking oil tank 14 is located on the right side where the heater 3 is present, and the oil purifying tank 15 is located on the left side where the heater 3 is not located.

Above the oil replenishing tank 15, a solid oil container 16 for replenishing solid oil, which is a rotatable top opening container, is detachably mounted. The solid oil container 16 has a bottom surface 17, a front surface 18, a side surface 19, and a rear surface 20, rotates around a rotation shaft 21 within a range of 90 degrees, and stops at an end point of the rotation. The mounting method of the solid oil container 16 is the rotation shaft 21.
Is fixed to the flange at the upper end of the oil replenishing tank 15 with bolts, magnets, and hooks so as to be detachable. The rear surface 20 is made slightly smaller than the opening of the oil refill tank 15 in accordance with the opening shape of the oil refill tank 15, so that the opening of the oil refill tank 15 is closed when the solid oil container 16 is turned downward by 90 degrees. ing.

Below the heater 3, a second partition plate 23 is arranged in a horizontal direction. The second partition plate 23 is formed of heat conductive stainless steel. Its horizontal height position is
It is the same height as the lower end of one partition plate 12. The arrangement method of the second partition plate 23 is such that a protrusion (not shown) is provided below the second partition plate 23 or a spacer (not shown) is inserted so as to provide an interval between the second partition plate 23 and the bottom surface of the oil tank 4. This is a method of placing the oil tank 4 on the bottom surface so that it can be emptied.

The upper space divided up and down by the second partition plate 23 is the cooking oil tank 14 described above, and the space formed below is the stationary oil tank 24.

The operation of the fryer 1 configured as described above will be described.

In FIG. 1, before the heater 3 is heated,
All the oil in the oil tank is solid and solid. When the heater 3 is energized to start dissolving the solid oil, it gradually liquefies. In the present invention, since the oil tank 4 is partitioned by the heat insulating first partition plate and the heat conductive second partition plate, a temperature difference occurs in the tank. The tank with the highest temperature is the cooking oil tank 14 including the heater 3, the next highest is the stationary oil tank 24, and the second is the additional oil layer 15.
Becomes The temperature of the cooking oil tank 14 is set to 180 ° C. by the temperature sensor 8.
When maintained around, the temperature of the stationary oil tank 24 is about 100
℃, the oil temperature of the oil replenishment tank 15 is about 70 ℃. For this reason, the function of the second partition plate 23 for preventing convection of oil and the function of the first partition plate 12 having a heat insulating function are very large.

As shown in FIG. 2, when the temperature of the cooking oil tank 14 reaches the cooking temperature, the ingredients 26 are put into the fried basket 25,
Hold the handle 27 and immerse it in the cooking oil tank 14. The food is heated, the water in the food evaporates, and oil enters the gap. As many fries are fried, the amount of oil in the cooking oil tank 14 decreases. Therefore, the interval between cooking operations is prepared to prepare for additional oil. The solid oil container 16 is rotated and raised, held in a horizontal position, and the solid oil 29 crushed to a suitable size is placed on the bottom surface 17 of the solid oil container 16.

As shown in FIG. 3, when the food material 26 is sufficiently fried, the handle 27 is removed together with the fried basket 25.
At this time, the oil is removed from the cooking oil tank 14 little by little.
Since the solid oil changes to a solid when cooled, when the food material 26 is cooled, it becomes a fried food with a crisp tactile sensation, which is preferred by consumers. When adding oil, the solid oil container 16 on which the solid oil 29 is placed is rotated downward. Since the solid oil 29 hits the front surface 18, it does not fall into the oil replenishment tank 15. When the rear surface 20 closes the opening of the oil refill tank 15, the oil reaches the oil refill tank 15 and is gradually liquefied by receiving residual heat. Although the temperature of the additional oil tank 15 is lowered because the cold solid oil 29 is mixed, the adjacent cooking oil tank 14 is not affected at all by the heat insulating action of the first partition plate 12. Therefore, the cooking operation can be continued. The oil in the refill tank 15 is filled with the first partition plate 12.
, Flows into the stationary oil tank 24 below the second partition plate 23, and enters the cooking oil tank 14 through the gap 30. As described above, even if the solid oil 29 is poured from above the oil replenishment tank 15, the
By the function of the first partition plate and the second partition plate, the solid oil previously melted is extruded and added to the cooking oil tank. Since a so-called first-in first-out effect is obtained, old oil does not stay and cold oil is not added. In addition, since the inside of the cooking oil tank 14 is convected only above the second partition plate 23, the oil in the stationary oil tank 24 is stirred and does not rise, so that it does not come into contact with air, so that it may be oxidized. And it is not easily deteriorated, and has an effect that the oil lasts a long time.

As shown in FIG. 4, when the fryer 1 is washed, when the oil is hot while the oil is kept in a liquid state, the valve 6 is closed.
And transfer the oil to the oil receiver 5. When all the oil has run out, the heater arm 9 is rotated to raise the heater 3 90 degrees. After that, the first partition plate 12, the second partition plate 23, and the solid oil container 16 are removed. Since the oil tank 4 can be emptied in this way, cleaning can be facilitated. Conversely, if the first partition plate and the second partition plate are added to a fryer dedicated to liquid oil, there is an advantage that it can be easily converted to a solid oil fryer.

Although the embodiment of the present invention has been described above, the present invention is not limited to this, and the heating element may use a heat pipe or electromagnetic induction. Further, a plurality of first partition plates may be placed at the front, rear, left and right of the oil tank, or may be placed at one corner of four corners. Further, the second partition plate does not need to be a flat plate, but may have a corrugated shape or an inverted U-shape, as long as it communicates with the oil replenishment tank. The first partition plate and the second partition plate may be connected in an L-shape by screwing, welding, or the like. further,
After the first partition plate and the second partition plate are integrally formed in the L-shape with the same material, the first partition plate may be given heat insulation by enamelling, ceramic spraying, or the like.

[0025]

As described above, according to the first aspect of the present invention, one side of the oil tank is divided into the cooking oil tank and the other side is divided into the additional oil tank by the first partition plate, and the upper portion of the heating element is divided by the second partition plate. Is divided into a cooking oil tank and a lower part into a stationary oil tank, and the additional oil tank is connected to the stationary oil tank. Therefore, the oil from the additional oil tank flows through the stationary oil tank to the cooking oil tank. Therefore, the oil temperature in the cooking tank is not reduced by the addition of the solid oil, and cooking can be continuously performed. In addition, since the oil in the cooking tank does not cause up-down convection, the oil is less deteriorated. is there.

According to the second aspect of the present invention, the heat of the cooking oil tank is prevented from escaping to the additional oil tank, and the heat of the cooking oil tank is transmitted to the stationary oil tank. Accordingly, since the high temperature of the cooking oil tank is transmitted to the stationary oil tank and the heat is transmitted to the oil replenishment tank, the oil replenishment tank does not require extra components such as a heater and a thermostat, and maintains the temperature of the oil replenishment tank at an appropriate temperature. effective.

According to the third aspect of the present invention, after the solid oil is put on the container, the container is rotated together with the container and the solid oil is charged into the additional oil tank. As it rotates, the solid oil is supported by the side surface of the container and gently sinks into the oil replenishing tank and is released from the opening, so that there is no oil splashing, and the oil replenishing operation can be performed safely. Also, after the refueling is over, the back of the container covers the opening of the refueling tank and covers it, preventing misuse such as accidentally putting food in the refueling tank or dropping foreign matter. Has the effect.

According to claim 4 of the present invention, an existing fryer for liquid oil can be easily modified.
Therefore, it is possible to provide a safe solid oil fryer at a low cost, and it is possible to easily clean the oil tank as before.
