DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fryer for preparing fried foods (so-called fried foods) by cooking foods such as frozen foods with oil, and in particular, to heat an object to be heated by a high-frequency electromagnetic induction method. The present invention relates to an electromagnetic fryer for cooking by heating.

[0002]

2. Description of the Related Art FIG. 3 is a block diagram showing a conventional example of this kind.
(A) is a top view thereof, and (B) is a cross-sectional view of the same seen from the front. In the figure, 1 is a fryer tank made of stainless steel, 2 is an object to be heated by high-frequency electromagnetic induction, 3 is a coil for passing an electric current, 4 is a basket for putting foods, and 5 is an oil (oil). And 6 indicate handles of the basket 4 respectively.

[0003] That is, a cylindrical body is provided in a fryer tank 1 to form a heated body 2, into which a coil 3 is inserted and a high-frequency current flows through the coil 3 to generate magnetic lines of force. This causes an eddy current to flow through the object to be heated 2 to heat the object to be heated 2 itself to heat the oil 5, and is well known as an electromagnetic induction heating method. When the temperature of the oil 5 reaches a predetermined temperature, food is put into the basket 4 and cooking is performed (fried).

[0004]

However, in the above-described structure, food (especially, frozen food) is put into a basket after the oil reaches a predetermined temperature, and is placed on a body to be heated. The object to be heated is rapidly cooled, causing a decrease in oil temperature, and as a result, a problem arises in that thermal efficiency is reduced. In addition, since the object to be heated is formed substantially at the center of the fryer tank, there is a problem that it is difficult to clean the fryer tank. SUMMARY OF THE INVENTION It is therefore an object of the present invention to prevent sudden cooling of an object to be heated and to prevent the object to be heated from obstructing cleaning.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to an electromagnetic fryer for cooking oil and heating foods by a high-frequency electromagnetic induction heating method, in which a part of a fryer tank is heat-resistant insulated. It is constituted by a plate, and a coil is disposed outside the plate, and a heated object is disposed inside the plate. In the present invention, the object to be heated can be provided detachably with respect to the fryer tank.

[0006]

The structure as described above, that is, by keeping the object to be heated away from the basket (or foodstuff), prevents the object to be heated from being rapidly cooled, thereby preventing a decrease in thermal efficiency. Further, by making the body to be heated detachable, cleaning is facilitated, maintenance is improved, and cooking suitable for food can be realized.

[0007]

FIG. 1 is a block diagram showing an embodiment of the present invention. As is clear from the figure, this embodiment is different from the conventional example shown in FIG. 3 in that a heat-resistant insulating plate 7 is provided in a part of the fryer tank 1, a coil 3A is provided on the outside, and a coating is provided on the inside. It is characterized in that the heating element 2A is provided, and that the heating element 2A can be detachably fitted into the fryer tank 1 or fixed with bolts and nuts. FIG. 1A is a sectional view of the flyer as viewed from the front, and FIG. 1B is a side sectional view of the flyer as viewed from the side. Reference numeral 8 denotes a cooling fin of the coil 3A.

[0008] That is, by keeping the heated object away from the food material, the heated object is not directly affected by the food material, thereby preventing the heated object from being rapidly cooled, thereby preventing a decrease in thermal efficiency. It is. In addition, by making the heated body 2A detachable from the fryer tank 1 here, cleaning is facilitated, and maintenance is improved.

FIG. 2 is a block diagram showing another embodiment of the present invention. This is because the surface of the object to be heated is not flat as shown in FIG.
By doing so, the effective heating area is substantially increased, whereby the object to be heated can be heated more efficiently. As described above, if the object to be heated is made detachable, not only the cleaning becomes easy, but also the object to be heated shown in FIG. 1 or FIG. 2 can be used depending on the food, and the heating suitable for the food can be performed. The advantage is that cooking can be easily realized.

[0010]

According to the present invention, a part of the fryer tank is constituted by a heat-resistant insulating plate, a coil is arranged outside the fryer tank, and a heated object is arranged inside the fryer tank. Is not rapidly cooled, so that a decrease in thermal efficiency can be prevented. Further, by making the object to be heated detachable, there is an advantage that not only cleaning can be simplified and maintenance performance can be improved, but also heating and cooking suitable for food materials can be easily realized. In addition, by making the surface of the object to be heated not a flat surface but a wavy shape, there is also obtained an advantage that the heating efficiency can be increased.
