Abstract

PROBLEM TO BE SOLVED: To solve the problems that when an oil tank of a fryer is made into an integrated form and heated, an upper part of the oil tank becomes hot, and a user may burn oneself by touching the upper part, or spilt beer may be heated while flowing on the upper part and may explode at a moment of falling in the oil tank. SOLUTION: A top cover 21 is formed as a separate body from an oil tank main body 3. Then, an overflow preventing section 9 which expands to the outside from the upper opening 5a of tank main sections 5 and 7 wherein a frying oil r is stored is provided for the oil tank main body 3. The top cover 21 is equipped with a peripheral wall 23 and a flange 25. In this case, the peripheral wall 23 surrounds the overflow preventing section 9 from the outside. The flange 25 covers the overflow preventing section 9 from the top by expanding to the inside from the peripheral wall 23. The peripheral wall 23 and the flange 25 are formed into sizes which do not come into contact with the overflow preventing section 9. Therefore, even when the oil tank main body 3 becomes hot by the frying oil r, the heat is prevented from being transmitted to the top cover 21, and even if the user touches the top cover 21, he or she is not burnt. Also, the spilt beer is prevented from dropping in the oil tank main body 3 under a heated state.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fryer (a fryer cooking pan with a heater), and more particularly to a fryer which is installed with its upper end protruding upward from a table.

[0002]

2. Description of the Related Art There are various types of fryers. For example, a fryer a in the form of a fryer a shown in FIG.
In the figure, b indicates an oil tank. The oil tank b has a box-shaped tank main part c having an open upper surface, and an upper opening edge d of the tank main part c.
And an oil drain portion e extending outward from the metal plate is integrally formed by a metal plate. The oil draining portion e has a flange-like inclined bottom portion f that projects slightly upward from the upper opening edge d to the outside, a short inner peripheral wall g that rises vertically from the outer periphery of the inclined bottom portion f, and an inner peripheral wall g. And an outer peripheral wall h folded outward and downward from the upper end, and an oil drain port i is formed in the inclined bottom portion f. A heater j is passed through the inner bottom of the tank main part c, a drain k is attached to a bottom wall of the tank main part c, and an oil collecting hose m is connected to the oil drain port i.

[0003] Such a fryer a is installed on the table n so as to fit into a cooker installation hole p formed in the table n, and only the oil drain portion e projects upward from the table n. A rectangular frame-shaped oil drain net q is placed on the oil drain portion e. Frying oil (edible oil) r for about 8 minutes is put into the tank main part c, and the frying oil r is heated by a heater j, and is heated to about 180 ° C. in an area above the heater j. , And in the lower region, the temperature is maintained at about 70 to 80 ° C. The cooked fried seeds are
If necessary, put on an oil-draining net q to cut off the oil. The oil flows down the inclined bottom part f of the oil drain part e and falls into the frying oil r of the tank main part c.

[0004]

In this fryer a, the heat of the heated frying oil r is directly conducted to the oil-cutting portion e, and the oil-cutting portion e may have a high temperature of about 100 ° C. in some cases. Therefore, there is a danger that the user touches the oil drain portion e and burns. In addition, it is not rare that the drink placed on the table n is accidentally spilled into the oil tank b. In this case, when the drink falls directly into the frying oil r without touching the oil drain e, the drink usually sinks to the bottom of the frying oil r before boiling, so that this does not often boil and explode, When spilled on oil drain e
In many cases, it is heated while flowing here and boil and explode as soon as it falls into the frying oil r.

[0005] In particular, since foaming substances such as beer are easy to adjust to oil, the frying oil r is boiled with vigorous foaming and scatters around, or the liquid level of the frying oil r rises and may be removed from the oil tank b. Sometimes it overflows. The oil outlet i is provided for the purpose of preventing such overflow, but cannot catch up when the boiling is severe.

The present invention has been made in view of the above-mentioned problems, and by devising the structure of the oil tank, it is possible to prevent the upper end of the oil tank from becoming high in temperature.
An object of the present invention is to provide a novel fryer that can almost certainly prevent a boiling explosion of a spilled drink or the like.

[0007]

In order to achieve this object, a fryer according to claim 1 heats an oil tank body, a top cover separate from the oil tank body, and frying oil in the oil tank body. The oil tank body has a spill-prevention portion that extends outward from the upper opening of the tank main portion in which frying oil is stored, and the top cover has a peripheral wall that surrounds the spill-over prevention portion from the outside. A flange that protrudes inward from the peripheral wall and covers the overflow prevention unit from above,
The peripheral wall and the flange have a size that does not touch the overflow prevention portion.

According to this fryer, by disposing the top cover so as not to contact the oil tank main body, even if the oil tank main body becomes hot due to the frying oil, the heat does not conduct to the top cover. The cover never gets hot. Therefore, there is no danger of burns even if you touch the top cover, and even if you spill a drink such as beer on the top cover, it will not be heated to a high temperature before it flows down into the oil tank body. It can almost certainly prevent a boiling explosion.

Although the top cover may be simply placed on the table, it is desirable to provide some positioning means for holding the top cover at a position where the top cover does not contact the oil tank body. As the means, in addition to the means described in claim 2, means for providing such a positioning portion on the table, means for detachably fixing the top cover to the table, and the like are conceivable.

The top cover according to the present invention has a function of preventing burns and the like caused by the heat of the oil tank.
By tilting the flange inward and downward, the same function as that of the oil drain portion e of the conventional fryer a can be obtained. In other words, if a frame-shaped grease net having the same size as the outer shape is placed on the flange having such a shape, the oil dropped from the net flows on the flange and is collected in the oil tank body. It is. In this case, if the inclined lower end of the flange is largely inserted into the tank main part, the flange may come into contact with the frying oil, so the size is set so that the inclined lower end is located near the upper opening of the tank main part. It is desirable to do.

According to a second aspect of the present invention, in the fryer according to the first aspect, the top cover is provided with a positioning portion which is in point contact or line contact with the overflow preventing portion at a plurality of positions from the side. It is characterized by the following. With this configuration, the mounting position of the top cover with respect to the oil tank body is determined by the contact of the positioning portion with the overflow prevention portion, so that the top cover is fixed to the table or the table is provided with positioning means for the top cover. You don't have to. In addition, since the top cover contacts the overflow preventing portion only at a plurality of points or lines, conduction of heat of the tank body to the top cover can be minimized. This positioning portion may be formed integrally with at least one of the top cover and the oil tank main body, or a separate member may be attached thereto.

A fryer according to claim 3 is the fryer according to claim 1 or 2, wherein the heater is
It is characterized by being mounted at a position higher than the bottom wall of the oil tank body. In this case, the frying oil in the oil tank main body becomes hot in a region higher than the heater, and is kept low in a region lower than the heater, so that the spilled oil has a synergistic effect with that the top cover does not become hot. Boiling explosion of drinks and the like can be more reliably prevented. That is,
This is because even if beer or the like is spilled on the top cover, the beer or the like flows down the low-temperature top cover and sinks in the low temperature range of the frying oil, so that there is no room for the beer or the like to be heated to a high temperature so as to boil.

According to a fourth aspect of the present invention, in the fryer according to any one of the first to third aspects, an oil drop hole is provided in an overflow prevention portion of the oil tank body. Therefore, even if the frying oil overflows from the tank main part of the oil tank main body to the overflow prevention part, the overflowing frying oil flows down from the oil drain hole to the intended place, so that the overflowing frying oil is removed. It can almost certainly be prevented from overflowing from the oil tank body.

According to a fifth aspect of the present invention, there is provided the fryer according to the fourth aspect, wherein a drain is attached to a bottom wall of the oil tank body, an oil receiving container is arranged below the drain, and an oil drain hole is provided. Connect one end of the collection hose,
The other end of the overflow oil recovery hose faces the oil receiving container. By doing so, the same container can be used for draining oil and recovering overflowing oil when replacing frying oil or cleaning the oil tank body, so that the space for oil recovery can be minimized. Also, the work of processing the recovered oil becomes easier.

[0015]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of a fryer 1 according to the present invention will be described below with reference to the embodiments shown in the drawings. [1. First Embodiment] (FIGS. 1 to 3) FIGS. 1 to 3 show a fryer 1 according to a first embodiment.
It is shown. This fryer 1 has an oil tank body 3
And a top cover 21 that covers the overflow prevention portion 9 that is the upper end of the oil tank main body 3, a heater 33, and the like.

[A. Oil tank main body] The oil tank main body 3 has a substantially upwardly expanding box shape, a fried portion 5 having an open upper surface, a bottom portion 7 continuing down from the fried portion 5, and an outer portion from the upper opening 5a of the fried portion 5. The spillover prevention portion 9 which is spread out is integrally formed of a stainless steel plate material.

The fry portion 5 has an upper opening 5a having a rectangular shape that is long in the left-right direction (a leftward direction is a leftward upward direction in FIG. 1 and a leftward downward direction is a frontward direction in FIG. 1). The peripheral wall 5b is substantially funnel-shaped because the front and rear sides are vertical and the left and right sides are inclined inward and downward at the lower ends. The bottom portion 7 is formed in a pocket shape having a substantially square upper opening, the upper opening is continuous with the lower opening of the fried portion 5, and the bottom wall is inclined downward to the right. An oil drain hole (not shown) is formed in the inclined lower end, and the drain 11 is attached to the oil drain hole. In these fried part 5 and bottom part 7,
A tank main part in which the frying oil r is stored is configured.

The overflow preventing portion 9 is provided with the upper opening 5 of the fry portion 5.
a bottom plate 9a in the form of a frame projecting horizontally outward from the opening edge of a, and a peripheral wall 9b rising from the outer periphery of the bottom plate 9a
The height of the peripheral wall 9b is 4 times the height of the fried portion 5.
It is about one-third. An oil drain hole 9c is formed on the right side of the bottom plate 9a, and a hose socket 13 is welded to the hole 9c.

[B. Top cover] Top cover 21
Is formed separately from the oil tank main body 3, and has a rectangular frame-shaped outer peripheral wall 23 when viewed from above and below.
And a flange 25 projecting inward from the upper end of the plate is integrally formed of a stainless steel plate material. The plane size and length of the outer peripheral wall 23 are the same as those of the peripheral wall 9 of the overflow prevention portion 9.
It is slightly larger than that of b. The flange 25 has a narrow top surface 25 extending horizontally along the upper edge of the outer peripheral wall 23.
a, an inner peripheral wall 25b having a small vertical width extending vertically downward from the top surface portion 25a, and 3 mm from the lower end of the inner peripheral wall 25b.
An oil-cut slope 25c that protrudes largely inward with a downward slope of about 0 ° is formed. The lower end of the slope of the oil-cut slope 25c is located at substantially the same height as the lower end of the peripheral wall 23.

[C. Heater, etc.] At a position where the fried portion 5 and the bottom portion 7 in the oil tank main body 3 are continuous with each other, a heater mounting pipe 31 is provided so as to penetrate therethrough in the front-rear direction. The heater attachment tube 31 has a thick cylindrical shape, and a heater 33 is provided in a housed shape. One end of an oil recovery hose 35 is connected to the hose socket 13. An oil receiving container 37 (see FIG. 3) is disposed below the drain 11, and the other end of the overflow oil recovery hose 35 faces the oil receiving container 37. Numeral 39 denotes an oil net. The oil drain net 39 has a rectangular frame shape, and the size of the oil drain net 39 fits inside the inner peripheral wall 25b of the overflow prevention part 9 and covers the entire oil drain slope part 25c. I have.

[D. Installation] The fryer 1 is configured as described above, and is installed, for example, on the table 41 of a kushiage store as follows. The table 41 has a rectangular cooker installation hole 41a slightly larger than the outer shape of the fried portion 5 at the center thereof, and a top cover positioning frame 45 arranged on the upper surface so as to surround the cooker installation hole 41a. It is fixed by bonding or screwing. The upper half portion of the cooker installation hole 41a is larger than the lower half portion, and a heat insulating material 43 made of a ceramic material is attached thereto. The top cover positioning frame 45 has such an inner circumference that the peripheral wall 23 of the top cover 21 fits snugly, and that the top cover positioning frame 45 is positioned evenly in the front-rear and left-right directions with respect to the cooker installation hole 41a. It is provided in.

The main body 3 of the oil tank is installed on the table 41 by the upper end of the frying part 5 being fitted into the cooker installation hole 41a and the bottom plate 9a of the overflow prevention part 9 being seated on the heat insulating material 43 (see FIG. 3). . Therefore, only the overflow prevention part 9 protrudes upward from the table 41. After the oil tank main body 3 is installed in this manner, the top cover 21 is attached to the peripheral wall 2 thereof.
3 is placed on the table 41 so that the lower end of the 3 fits into the top cover positioning frame 45. As a result, the overflow prevention unit 9
Is covered by the top cover 21.

The top cover 21 thus placed is
As can be seen from FIG. 3, none of the portions comes into contact with the overflow prevention portion 9. That is, the size of the top cover 21 with respect to the overflow prevention portion 9 is as described above, and the cooking device installation hole 4 of the top cover positioning frame 45 is provided.
This is because the position with respect to 1a is not deviated in any of the front and rear directions and the left and right directions, so that a certain amount of space is left between the peripheral wall 23 or the flange 25 of the top cover 21 and the overflow prevention portion 9.

[E. Usage and Action] The oil tank body 3
Add an appropriate amount of the desired frying oil r. As shown in FIG. 3, the amount is set such that the liquid level of the frying oil r is lower than the upper opening 5 a of the frying portion 5 to some extent. When a control panel (not shown) is turned on, the heater 33 generates heat to heat the frying oil r. The heated frying oil r causes convection as shown by an arrow in FIG. 3, and as a result, in a region higher than the heater 33, a high temperature required for frying (for example, 180)
(Approximately C), and in the lower region,
It is kept at about 80 ° C. Therefore, the frying cooking is performed near the liquid level of the frying oil r. Also, the bottom 7
It is unlikely that scum or water sinking in the surface will rise or cause a steam explosion.

When performing fried cooking, the top cover 21
Put an oil gauze net 39. The oil drain net 39 is placed horizontally on the highest peripheral edge of the oil drain slope 25c.
Therefore, if the deep-fried seeds s are put on this oil-draining net 39, excess oil is passed through the oil-draining net 39 and the oil-draining slope 25
After dropping on the oil c, the oil flows down the oil-cut slope 25c and falls into the frying oil r in the oil tank body 3.

As described above, since the top cover 21 is provided so as not to contact the overflow prevention portion 9, even if the oil tank main body 3 is heated by the heat of the frying oil r, the top cover 21 is kept in the oil tank main body 3 Only by receiving the radiant heat from the frying oil r, the heat does not directly conduct to the top cover 21, but reaches a temperature slightly higher than room temperature. Therefore, even if the top cover 21 is touched, burns cannot occur, and beer or the like cannot be burned.
Even if spilled, the spilled drink will not be heated to a high temperature before flowing down into the frying oil r, so that there is no danger that the spilled drink will boil and explode in the frying oil r. In particular, in the fryer 1, the temperature of the frying oil r is kept low at the bottom 7, so that the drink spilled on the frying oil r does not float or boil while sinking at the bottom of the frying oil r. .

[2. Second Embodiment] (FIG. 4) FIG. 4 shows a flyer 1A according to a second embodiment. The difference between this fryer 1A and the fryer 1 shown in the first embodiment is that
The only difference is that the means for positioning the top cover with respect to the oil tank body is provided on the top cover itself. Therefore, the explanation is made only for this difference, and for the rest,
The description will be omitted by giving the same reference numerals to the same parts in the fryer 1 to the respective parts in the drawing.

On the peripheral wall 23 of the top cover 21 of the fryer 1A, a small positioning projection 23a is formed by being pushed inward. This positioning projection 23
“a” has a hemispherical shape, and is provided on the front, rear, left and right side portions of the peripheral wall 23, two at a large distance from each other. The projecting length of the positioning projection 23a is approximately half the dimensional difference between the peripheral wall 9b of the overflow prevention part 9 and the peripheral wall 23 of the top cover 21 in the front-rear and left-right directions.

Therefore, when the top cover 21 is put on the oil tank main body 3 so that the top cover 21 covers the oil tank main body 3, the apex of the positioning projection 23 a comes into light contact with the peripheral wall 9 b of the overflow prevention section 9 from the outside, and the top cover 21 contacts the oil tank main body 3. Positioning in a horizontal plane is performed. Since the contact of the positioning projection 23a with the overflow prevention part 9 is only a point contact, the oil tank body 3
The heat conduction from the top to the top cover 21 can be minimized. Therefore, since the top cover 21 does not become hot, there is no danger of burns even if the top cover 21 is touched.
Even if you spill a drink on one, it won't get hot at once.

The positioning projection 23a may be in the form of a vertically long or horizontally long ridge, and it is also effective to attach a sheet having good heat insulation to the top.

The embodiment of the present invention has been described above.
The specific configuration of the present invention is not limited to this embodiment, and any change in design or the like without departing from the spirit of the present invention is also included in the present invention.

[0032]

As described above, according to the present invention, even if the temperature of the oil tank body becomes high due to the frying oil, the heat does not conduct to the top cover, so that the top cover does not become high temperature. Therefore, there is no danger of burns even if you touch the top cover, and even if you spill a drink such as beer on the top cover, it will not be heated to a high temperature before it flows down into the oil tank body, so beer and other drinks can be fried. It is possible to almost certainly prevent a boiling explosion from occurring.

According to the second aspect of the present invention, the mounting position of the top cover with respect to the oil tank main body is determined by the contact of the positioning portion with the overflow prevention portion, so that there is no need to provide a positioning means for the top cover on the table. . Moreover,
Since the top cover contacts the overflow prevention part only at a plurality of points or lines, conduction of heat of the tank body to the top cover can be minimized.

According to the third aspect of the present invention, the frying oil in the oil tank body has a high temperature in a region higher than the heater,
Since the temperature is kept low in the lower region, the boiling explosion of the spilled drink or the like can be more reliably prevented by a synergistic effect with the fact that the top cover does not become hot. That is, even if beer or the like is spilled on the top cover, they flow through the top cover which is not high in temperature and sink in the low temperature range of the frying oil, so that there is no room to be heated to a high temperature as the beer or the like boils. .

According to the fourth aspect of the invention, even if the frying oil overflows from the main portion of the oil tank main body to the overflow preventing portion, the overflowing frying oil flows down from the oil drop hole to the target. As a result, it is possible to almost certainly prevent the overflowed frying oil from flowing out of the oil tank main body.

According to the fifth aspect of the present invention, the draining of oil and the recovery of overflowing oil can be performed in the same container when replacing the frying oil or cleaning the oil tank main body. The space is minimized and the work on the recovered oil is easier.
