BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shabu-shabu pan for an electromagnetic cooker, which is used for cooking shabu-shabu using a tabletop electromagnetic cooker as a heating source.

[0002]

2. Description of the Related Art Shabu-shabu pot dishes are cooked while heating a pot (cooking: hot water for shabu-shabu) with a heat source (gas combustor) installed on a table. In order to prevent the pot from standing up, the pot to be used generally has a chimney part that penetrates from the bottom part at the center of the container part (Shokai 59-19025).
issue).

By the way, an electromagnetic cooker supplies a high frequency current of 20 to 50 kHz to a spiral heating coil to generate a radial magnetic flux from the center of the spiral, which is then added to a pan on a top plate (pot mounting table: crystallized glass). An eddy current is generated, and the Joule heat of the eddy current causes the pot itself to generate heat, which is used for cooking. Therefore, it is not particularly necessary to use a pan with a chimney portion in the center of the pan for shabu-shabu dishes.

Therefore, there is no conventional shabu-shabu pot used in an electromagnetic cooker, and even if the conventional chimney-type shabu-shabu pot for gas heating is used in an electromagnetic cooker, the heating area of the pot ( Since the magnetic flux crossing area: the area close to the top plate) is small and effective electromagnetic induction heating cannot be performed, cooking of shabu-shabu dishes was performed using a pot for general electromagnetic cooking.

[0005]

[Problems to be solved by the invention] Since the idea that shabu-shabu dishes using an electromagnetic cooker are cooked in a pan with a chimney is familiar, it is equipped with a chimney similar to the one heated by gas. Use of hot pot is desired. Therefore, the present invention proposes a shabu-shabu pan for an electromagnetic cooker.

[0006]

[MEANS FOR SOLVING THE PROBLEMS] A shabu-shabu pan for an electromagnetic cooker according to the present invention is made of a material capable of induction heating, and has a bottom portion corresponding to a large flat surface so that effective induction heating can be performed. And a chimney portion having a diameter of about 5 cm and penetrating vertically through the container portion.

[0007]

[Function] When a chimney body of a desired size is simply added to a pot for an ordinary electromagnetic cooker and the cooking tank portion is formed into a donut shape, the bottom of the chimney portion containing no water is overheated. turn into. Further, if the bottom surface of the chimney portion is removed and penetrated vertically, the heating area is reduced and the cooker cannot be used efficiently. However, if the diameter of the vertically penetrating chimney is 5 cm or less, it corresponds to the shape of the heating coil of the electromagnetic cooker, so that there is little leakage flux and efficient electromagnetic induction heating is performed.

[0008]

EXAMPLE An example of the present invention will be described below. <First Embodiment> FIGS. 1 and 2 show a first embodiment of the present invention. A shabu-shabu ladle according to this embodiment has a pot body including a container portion 1 and a chimney portion 2, a lid body 3, and a lid body 3. Composed of.

The container portion 1 is made of a material capable of induction heating, such as iron or stainless steel (excluding non-magnetic material), and its bottom surface has a large flat area so that sufficient electromagnetic induction heating is generated. The chimney part 2 is formed by vertically penetrating the center of the container part 1 such that the lower part (bottom part of the container part) A has a diameter of 5 cm or less. The lid 3 is provided with a chimney hole in the center.

Thus, when the seasoning liquid is poured into the container portion 1 and placed on the table top of an electromagnetic cooker and the cooker is energized, the magnetic flux generated by the spiral heating coil is generated from the center of the heating coil. It becomes radial and passes through the bottom surface of the container portion 1, and concentric circular eddy currents flow on the bottom surface of the container portion 1 in response to changes in the magnetic flux, and the container portion 1 is heated by Joule heat of the eddy current, and the seasoning is performed. The liquid is boiled and shabu-shabu is cooked.

Especially in the above heating, since the center of the container 1, that is, the center of the lower hole of the chimney 2 does not intersect with the magnetic flux and the penetrating area of the chimney 2 is made small, the heat generation efficiency is lowered. There are very few, and there is no problem in cooking.

<Second Embodiment> FIGS. 3 and 4 show a second embodiment of the present invention. This embodiment solves the problem caused by using a pan material compatible with an electromagnetic cooker. Like the first embodiment, it is composed of a container portion 4 and a chimney portion 5, and the diameter of the through hole in the lower portion of the chimney portion 5 (bottom surface of the container portion) is 5 cm or less.

The container portion 4 and the chimney portion 5 are separately formed, and the container portion 4 is formed in the center of the main body 41 with a through hole 42 having a size smaller than a predetermined size.
And the peripheral portion of the through hole 42 is bent upward and folded back downward to form the inner peripheral surface of the through hole 42.
3 is formed, while the chimney part 5 has a lower part 5
1 is formed in such a size that it can be closely fitted in the joint portion 43. Then, the lower portion 51 of the chimney portion is fitted into the joint portion 43 and welded to form a pot.

The electromagnetic cooker must be made of a magnetic material and cannot be made of copper as in the conventional gas heating shabu-shabu pot or austenitic chrome steel such as 18-8 stainless steel. Such a ferritic chromium steel must be used, but in the case of ferritic chromium steel, the welded portion becomes brittle and there is a risk that cracking may occur at the welded portion due to repeated heating. For example, in FIG.
As shown in Fig. 6, if the structure is such that the lower edge of the chimney is folded back and directly welds to the bottom of the container as in the previous shabu-shabu pan, the welded part a on the bottom of the container is cracked and cannot be used. There is a case to meet.

However, when formed as in the above-mentioned embodiment of the present invention, there is an advantage that even if the base material portion of the welded portion becomes brittle, it does not hinder the use.

In the present invention, the through hole area below the chimney at the center of the bottom of the container where electromagnetic induction heating is generated is not more than a predetermined size, and the shape of the chimney itself and the connecting structure with the container are arbitrary. Can be specified in.

[0017]

As described above, the present invention is a pan provided with a chimney portion of a size not larger than a predetermined size in the center of the pan body, which can be used for shabu-shabu dishes with an electromagnetic cooker without any trouble.
