Description

本発明は、一般家庭のキッチンで使用する加熱調理器に使用する、防汚に優れ、自己温度制御機能と過昇防止が実現できる加熱調理器用加熱容器に関するものである。   The present invention relates to a heating container for a heating cooker that is excellent in antifouling and that can realize a self-temperature control function and prevention of overheating, which is used in a heating cooker used in a general household kitchen.

加熱調理器として代表的な電磁調理器は、トッププレートの下側に加熱コイルを配置し、加熱コイルで生じた磁力線によりトッププレート上の誘導加熱調理器用鍋の底面内に渦電流を起こし発熱させるようになっており、従来、このような誘導加熱調理器用鍋として、磁性金属材料からなる鍋（鉄、ＳＵＳ４３０系ステンレス）と、磁性金属材料（鉄、ＳＵＳ４３０系ステンレス）と非磁性金属材料（アルミニウム、ＳＵＳ３０４系ステンレス）の２層または多層クラッド材からなる鍋がよく使用されている。   A typical electromagnetic cooker as a heating cooker has a heating coil disposed below the top plate, and generates heat by generating an eddy current in the bottom surface of the induction heating cooker pan on the top plate by the magnetic lines generated by the heating coil. Conventionally, as a pan for such an induction heating cooker, a pan made of a magnetic metal material (iron, SUS430 stainless steel), a magnetic metal material (iron, SUS430 stainless steel), and a nonmagnetic metal material (aluminum) SUS304 stainless steel) is often used.

ここで、この種の従来の誘導加熱調理器用鍋では、底面外周近傍に複数の突起を設けているものがある（例えば、特許文献１参照）。また、誘導加熱調理器用鍋の底面に自己温度制御機能を有する磁性金属材料を形成しているものがある（例えば、特許文献２参照）。   Here, in this kind of conventional pans for induction heating cookers, there are those provided with a plurality of protrusions in the vicinity of the outer periphery of the bottom surface (see, for example, Patent Document 1). Moreover, there exists what has formed the magnetic metal material which has a self-temperature control function in the bottom face of the pan for induction heating cooking appliances (for example, refer patent document 2).

図５は、特許文献１に記載された従来の誘導加熱調理器用鍋を示すものであり、図に示すように、磁性金属材料で形成した鍋本体１と鍋本体１の底面外周近傍に鍋本体１を支持する突起２を複数形成し、誘導加熱調理器のプレート３に載置され、突起２の高さを５ｍｍ以下として熱変形による鍋底の下方へのそりよりも突起２の高さを高くし、鍋本体１の底面加熱部４をプレート３から浮かせた構成にしている。   FIG. 5 shows a conventional pan for induction heating cooker described in Patent Document 1, and as shown in the figure, the pan body 1 formed of a magnetic metal material and the pan body in the vicinity of the bottom periphery of the pan body 1. A plurality of protrusions 2 that support 1 are formed, placed on the plate 3 of the induction heating cooker, and the height of the protrusions 2 is set to 5 mm or less, and the height of the protrusions 2 is higher than the downward warp of the pan bottom due to thermal deformation. The bottom heating unit 4 of the pan body 1 is lifted from the plate 3.

次に、図６は、特許文献２に記載された従来の誘導加熱調理器用鍋を示すものであり、図に示すように、非磁性金属材料からなる鍋本体１１と所定のキュリー温度を有する磁性金属材料１２を鍋本体１１の底面で一体化し、誘導加熱調理器のプレート１３に載置し、加熱コイル１４により誘導加熱される部分に磁性金属材料１２を配設した構成にしている。
実開平６−８１４１４号公報 特開平４−２２０９８９号公報 Next, FIG. 6 shows a conventional pan for an induction heating cooker described in Patent Document 2, and as shown in the figure, a pan body 11 made of a nonmagnetic metal material and a magnetic material having a predetermined Curie temperature. The metal material 12 is integrated on the bottom surface of the pan body 11, placed on the plate 13 of the induction heating cooker, and the magnetic metal material 12 is disposed on the portion that is induction heated by the heating coil 14.
Japanese Utility Model Publication No. 6-81414 Japanese Patent Laid-Open No. 4-220989

しかしながら、前記従来の特許文献１の構成では、調理時の鍋底の加熱膨張による変形を、鍋本体１を支持する複数の突起２によって防止し、誘導加熱される鍋本体１の底面形状を安定保持して常に加熱調理可能な構成としているが、同一磁性金属材料で形成した複数の突起２は、局所的に加熱され当接したプレート３が高温になり、煮こぼれや油付着による焦げ付き固着がプレート３の清掃しにくい汚れになりやすいという課題を有していた。   However, in the structure of the above-mentioned conventional Patent Document 1, deformation due to heating and expansion of the pan bottom during cooking is prevented by a plurality of protrusions 2 that support the pan main body 1, and the bottom shape of the pan main body 1 that is induction-heated is stably maintained. However, the plurality of protrusions 2 formed of the same magnetic metal material are heated locally and the plate 3 that is in contact with the plate becomes hot, and the sticking due to spillage or oil adhesion is the plate. 3 had the subject that it became easy to become dirt which is hard to clean.

また、突起２の高さが大きくなればなるほど、誘導加熱する加熱コイルと底面加熱部４の距離が離れてしまい、種々の調理に必要な所定の電力を鍋本体１に入力することができなくなるとともに、鍋本体１の温度制御をするための誘導加熱調理器本体内に設けられるであろう温度センサーなどとの距離も離れ、鍋本体１の温度制御および過昇防止が困難になるという課題を有していた。   Further, as the height of the protrusion 2 increases, the distance between the heating coil for induction heating and the bottom surface heating unit 4 increases, and it becomes impossible to input predetermined power required for various cooking to the pan body 1. In addition, the distance from the temperature sensor or the like that would be provided in the induction heating cooker body for controlling the temperature of the pan body 1 is also increased, making it difficult to control the temperature of the pan body 1 and prevent overheating. Had.

次に、前記従来の特許文献２の構成では、プレート１３と鍋本体１１の磁性金属材料１２が当接しているため、加熱部の隙間に入り込んだ煮こぼれや油付着による焦げ付き固着がプレート１３の清掃しにくい汚れになりやすいという課題を有していた。   Next, in the structure of the above-mentioned conventional patent document 2, the plate 13 and the magnetic metal material 12 of the pan body 11 are in contact with each other. There was a problem that it was easy to get dirty that was difficult to clean.

また、一般に市場に提供されている電磁調理器用鍋の大半は、前述した鉄等の所定のキュリー温度を有しない磁性金属材料からなるため、鍋の温度制御をするための温度センサーなどを誘導加熱調理器本体内の磁性金属材料１２に近いプレート１３の裏面近傍に設けることが必要になるが、磁性金属材料１２の加熱による熱伝導で誘導加熱調理器本体内の温度センサーが所定の温度を検知して、所定のキュリー温度に到達すれば自己温度制御をする磁性金属材料１２より先に電力制御動作をすることで調理性能を損なうといった課題を有していた。   In addition, most of the pots for electromagnetic cookers that are generally available on the market are made of magnetic metal materials that do not have the prescribed Curie temperature, such as iron, as described above, so induction heating is used to control the temperature of the pot. Although it is necessary to provide near the back surface of the plate 13 close to the magnetic metal material 12 in the cooker body, the temperature sensor in the induction heating cooker body detects a predetermined temperature by heat conduction by heating the magnetic metal material 12. When the temperature reaches a predetermined Curie temperature, there is a problem that the cooking performance is impaired by performing the power control operation before the magnetic metal material 12 that performs self-temperature control.

本発明は、前記従来の課題を解決するもので、煮こぼれ、油付着による加熱時の焦げ付き固着を無くし、プレートの防汚性能を向上するとともに、種々の調理に適した自己温度制御と過昇防止を精度よく実現できる加熱調理器用加熱容器を提供することを目的とする。   The present invention solves the above-mentioned conventional problems, eliminates sticking when heated due to boiling or oil adhesion, improves the antifouling performance of the plate, and controls self-temperature control and overheating suitable for various cooking. It aims at providing the heating container for heating cookers which can implement | achieve prevention accurately.

前記従来の課題を解決するために、本発明の加熱調理器用加熱容器は、所定のキュリー温度を有する磁性金属材料からなる加熱容器の底面外周部に下方に突出した凸脚部を設け、加熱容器の底面中央部は、上方に突出した凸中央部としたものである。   In order to solve the above-mentioned conventional problems, the heating container for a heating cooker according to the present invention is provided with a convex leg portion projecting downward on the outer peripheral portion of the bottom surface of the heating container made of a magnetic metal material having a predetermined Curie temperature. The center portion of the bottom surface is a convex center portion protruding upward.

これによって、加熱容器とこれを載置するプレート面間に隙間ができ、加熱時のプレート面への熱伝導が少なく凸脚部のプレート接触面での加熱も軽微なため、煮こぼれ、油付着による加熱時の焦げ付き固着を無くすことができるとともに、凸中央部の作用により、本体機器側の温度制御に依存することなく種々の調理に適した自己温度制御と過昇防止を精度よく実現できる。   As a result, there is a gap between the heating container and the plate surface on which it is placed, and there is little heat conduction to the plate surface during heating, and heating on the plate contact surface of the convex leg is slight. It is possible to eliminate the sticking and sticking at the time of heating due to the heating, and it is possible to accurately realize self-temperature control and prevention of overheating suitable for various cooking without depending on the temperature control on the main body side by the action of the convex central part.

本発明の加熱調理器用加熱容器は、加熱調理器のプレートの防汚性能を向上するとともに、本体機器側の温度制御に依存することなく種々の調理に適した自己温度制御と過昇防止を精度よく実現できるものである。   The heating container for a heating cooker according to the present invention improves the antifouling performance of the plate of the heating cooker and is accurate for self-temperature control and overheating prevention suitable for various cooking without depending on the temperature control on the main unit side. It can be realized well.

第１の発明は、所定のキュリー温度を有する磁性金属材料からなる加熱容器の底面外周部に下方に突出した凸脚部を設け、加熱容器の底面中央部は、上方に突出した凸中央部とした加熱調理器用加熱容器とすることにより、加熱容器とこれを載置するプレート面間に隙間ができ、加熱時のプレート面への熱伝導が少なく凸脚部のプレート接触面での加熱も軽微なため、煮こぼれ、油付着による加熱時の焦げ付き固着を無くすことができるとともに、凸中央部の作用により、調理器本体側の温度制御に依存することなく種々の調理に適した自己温度制御と過昇防止を精度よく実現できる。   1st invention provides the convex leg part which protruded below in the bottom-surface outer peripheral part of the heating container which consists of magnetic metal materials which have predetermined | prescribed Curie temperature, and the bottom center part of a heating container is the convex center part which protruded upwards By using the heating container for the heating cooker, there is a gap between the heating container and the plate surface on which it is placed, and there is little heat conduction to the plate surface during heating, and heating on the plate contact surface of the convex leg is light For this reason, it is possible to eliminate burning and sticking when heated due to oil sticking, and the self-temperature control suitable for various cooking without depending on the temperature control on the cooker body side by the action of the convex center part It is possible to accurately prevent over-rise.

第２の発明は、特に、第１の発明において、加熱容器の凸脚部は、加熱容器の加熱源外周縁より外側に位置して設けたことにより、凸脚部のプレート接触面での加熱を激減することとなり、プレートの防汚性能をさらに向上することができる。   According to a second invention, in particular, in the first invention, the convex leg portion of the heating container is provided on the outer side of the outer peripheral edge of the heating source of the heating container, so that heating of the convex leg portion on the plate contact surface is performed. As a result, the antifouling performance of the plate can be further improved.

第３の発明は、特に、第１の発明において、凸脚部は非磁性金属材料から成り、加熱容器と一体形成したことにより、凸脚部のプレート接触面が加熱されないため、温度上昇が激減することとなり、プレートの防汚性能をさらに向上することができる。   In the third invention, in particular, in the first invention, the convex leg portion is made of a non-magnetic metal material, and the plate contact surface of the convex leg portion is not heated by being integrally formed with the heating container. Thus, the antifouling performance of the plate can be further improved.

第４の発明は、特に、第１の発明において、加熱容器とこの加熱源とのギャップ寸法が加熱容器に３ｋＷ以下の電力が入力できるように凸脚部の高さを設定したことにより、本体機器側の温度制御に依存することなく、調理器本体側から加熱容器に３ｋＷを最大電力とする入力を自由に設定して、種々の調理に適した高火力が得られ、自己温度制御と過昇防止を精度よく実現できる。   According to a fourth aspect of the invention, in particular, in the first aspect of the invention, the height of the convex leg portion is set so that the gap dimension between the heating vessel and the heating source can input power of 3 kW or less to the heating vessel. Regardless of the temperature control on the equipment side, the input to set the maximum power of 3 kW to the heating vessel from the cooker body side can be freely set, and high heating power suitable for various cooking can be obtained. Prevention of ascent can be realized with high accuracy.

以下、本発明の実施の形態について、図面を参照しながら説明する。なお、この実施の形態によって本発明が限定されるものではない。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

（実施の形態１）
図１は、本発明の実施の形態１における加熱調理器用加熱容器を示すものである。 (Embodiment 1)
FIG. 1 shows a heating container for a cooking device according to Embodiment 1 of the present invention.

図は加熱調理器として誘導加熱調理器を例示しているものであり、所定のキュリー温度を有する磁性金属材料からなる加熱容器２１は、平滑な底面加熱部２２の底面外周部、望ましくは直接誘導加熱されない最外周近傍の円周上に、下方に突出して凸脚部２３を設け、底面中央部は、上方に突出した凸中央部２４とし、側面には把手２５が取り付けられている。誘導加熱調理器本体２６の最上部に設けられたプレート２７の下方には、加熱容器２１の加熱源となる誘導加熱用の加熱コイル２８がドーナツ状に巻かれ、コイル内周縁２９とコイル外周縁３０を形成して加熱コイルベース３１に固着されている。温度制御装置３２は、加熱コイル２８のコイル内周縁２９を通って加熱容器２１の略中央に相対するように、プレート２７の裏面に当接するよう構成され、制御部３３と電気的につながっている。   The figure exemplifies an induction heating cooker as a heating cooker. A heating container 21 made of a magnetic metal material having a predetermined Curie temperature is a bottom outer peripheral portion of a smooth bottom heating portion 22, preferably direct induction. On the circumference near the outermost periphery that is not heated, a convex leg portion 23 is provided that protrudes downward, a central portion of the bottom surface is a convex central portion 24 that protrudes upward, and a handle 25 is attached to the side surface. Below the plate 27 provided at the top of the induction heating cooker body 26, a heating coil 28 for induction heating, which serves as a heating source for the heating container 21, is wound in a donut shape. 30 is formed and fixed to the heating coil base 31. The temperature control device 32 is configured to contact the back surface of the plate 27 so as to face the approximate center of the heating container 21 through the coil inner peripheral edge 29 of the heating coil 28, and is electrically connected to the control unit 33. .

加熱容器２１は、加熱コイル２８の外周縁より大きな底面径を有しており、プレート２７上に載置され、加熱コイル２８により誘導加熱されるものである。ここで、凸脚部２３は、プレート２７面との接触面積を可能な限り小さくしている。また、凸中央部２４は、加熱容器２１の底面において、温度制御装置３２による温度制御に全く依存しないように加熱コイル２８の内周縁２９の直径よりも小さくし、同心円状に上方に突出させている。   The heating container 21 has a larger bottom diameter than the outer peripheral edge of the heating coil 28, is placed on the plate 27, and is induction-heated by the heating coil 28. Here, the convex leg part 23 makes the contact area with the plate 27 surface as small as possible. Further, the convex central portion 24 is made smaller than the diameter of the inner peripheral edge 29 of the heating coil 28 on the bottom surface of the heating container 21 so as not to depend on temperature control by the temperature control device 32 at all, and is projected upward in a concentric manner. Yes.

以上のように構成された加熱調理器用加熱容器について、以下、その動作、作用を説明する。   About the heating container for heating cookers comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

まず、電源が供給され使用者が所定の火力を設定し、調理物を投入して通電を開始すると、加熱コイル２８に誘導加熱するための電力が供給され、加熱容器２１の底面加熱部２２に放射された交番磁束により誘起された渦電流が流れ、ジュール熱により底面加熱部２２が加熱される。このとき、誘導加熱調理器本体２６の温度制御装置３２は、底面加熱部２２の温度上昇を所定の制御プログラムに従い、プレート２７の温度上昇を介して常に検知し、その情報を電気的に制御部３３に伝達している。調理物が出来上がりに近づくと、加熱容器２１が所定のキュリー温度に到達し、急速に非磁性体へと変化するため、制御部３３により所定の電力を低下させる。このとき低下した電力は、加熱容器２１を構成する磁性金属材料の材質、厚み、形状などで可変にすることができる。次に、電力の低下に伴い加熱容器２１も温度低下し、所定のキュリー温度を下回ると再び磁性を取り戻すため、当初の電力で再び加熱容器２１の加熱を始める。この繰り返しにより、調理メニューに応じた自己温度制御と、過昇防止機能を精度よく実現できる。   First, when power is supplied and the user sets a predetermined heating power, puts food and starts energization, electric power for induction heating is supplied to the heating coil 28, and the bottom heating unit 22 of the heating container 21 is supplied to the bottom heating unit 22. Eddy currents induced by the radiated alternating magnetic flux flow, and the bottom surface heating unit 22 is heated by Joule heat. At this time, the temperature control device 32 of the induction heating cooker main body 26 always detects the temperature rise of the bottom surface heating unit 22 according to a predetermined control program through the temperature rise of the plate 27, and the information is electrically controlled by the control unit. 33. When the cooked food is almost finished, the heating container 21 reaches a predetermined Curie temperature and rapidly changes to a non-magnetic material, so the control unit 33 reduces the predetermined power. The power reduced at this time can be made variable depending on the material, thickness, shape, etc. of the magnetic metal material constituting the heating container 21. Next, as the electric power decreases, the temperature of the heating container 21 also decreases. When the temperature drops below a predetermined Curie temperature, the magnetism is restored again, and thus heating of the heating container 21 is started again with the initial electric power. By repeating this, self-temperature control according to the cooking menu and an over-rise prevention function can be realized with high accuracy.

ここで、加熱容器２１の凸中央部２４は、温度制御装置３２の温度検知が不可能な程度にプレート２７から一定の距離だけ離れているため、この一連の調理中に温度制御装置３２による制御プログラムが動作することはない。   Here, since the convex central portion 24 of the heating container 21 is separated from the plate 27 by a certain distance to such an extent that the temperature control device 32 cannot detect the temperature, the control by the temperature control device 32 is performed during this series of cooking. The program will not work.

また、凸脚部２３は、その配置構成により、プレート２７面への熱伝導を減少させプレート接触面での加熱が軽微となり、加熱時のプレート温度上昇を減少させることができ、煮こぼれ、油付着による焦げ付き固着などの清掃しにくい汚れを防止することができる。   Moreover, the convex leg part 23 can reduce the heat conduction to the surface of the plate 27 by the arrangement configuration, the heating on the plate contact surface becomes light, and the rise in the plate temperature at the time of heating can be reduced. It is possible to prevent dirt that is difficult to clean, such as burnt sticking due to adhesion.

なお、所定のキュリー温度を有する加熱容器２１の磁性金属材料としては、例えば、ニッケル合金などがあるが、鍋類の用途に応じた材質を含め、設定温度や機械的強度、加工性などにより便宜選ぶことができる。また、加熱容器２１は、鍋、やかん、フライパン、天ぷら鍋、玉子焼き器など種々の調理に適したものを便宜選ぶことができる。また、凸脚部２３は、連続して下方に突出した形状としたが、本実施の形態で説明した効果を有すれば、例えば、複数のリブ形状であってもよい。   Note that the magnetic metal material of the heating container 21 having a predetermined Curie temperature includes, for example, a nickel alloy. However, depending on the set temperature, mechanical strength, workability, etc. You can choose. Moreover, the heating container 21 can select conveniently the thing suitable for various cooking, such as a pan, a kettle, a frying pan, a tempura pan, and an egg-baking machine. Moreover, although the convex leg part 23 was made into the shape which protruded below continuously, if it has the effect demonstrated by this Embodiment, it may be a some rib shape, for example.

（実施の形態２）
図２は、本発明の実施の形態２における加熱調理器用加熱容器を示すものである。なお、本実施の形態の基本構成は、実施の形態１と同じなので異なる点を中心に説明する。また、実施の形態１と同じ構成には同じ符号を付してその説明を省略する。 (Embodiment 2)
FIG. 2 shows a heating container for a cooking device according to Embodiment 2 of the present invention. Since the basic configuration of the present embodiment is the same as that of the first embodiment, the description will focus on the differences. The same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

本実施の形態においては、加熱容器２１の凸脚部２３が加熱コイル２８のコイル外周縁３０よりも外側に位置して設けられているものである。すなわち、図に示すように、加熱容器２１は、誘導加熱する加熱コイル２８の外周縁より大きな底面径を有し、凸脚部２３は直接誘導加熱されない底面最外周近傍に配設して構成したものである。   In the present embodiment, the convex leg portion 23 of the heating container 21 is provided outside the coil outer peripheral edge 30 of the heating coil 28. That is, as shown in the figure, the heating vessel 21 has a bottom surface diameter larger than the outer peripheral edge of the heating coil 28 for induction heating, and the convex leg portion 23 is arranged near the outermost periphery of the bottom surface that is not directly induction heated. Is.

このように、本実施の形態の構成により、プレート２７の温度上昇はさらに激減され、焦げ付き固着などの清掃しにくい汚れを防止することができる。   Thus, with the configuration of the present embodiment, the temperature rise of the plate 27 is further drastically reduced, and it is possible to prevent dirt that is difficult to clean, such as scorching adhesion.

（実施の形態３）
図３は、本発明の実施の形態３における誘導加熱調理器用加熱容器を示すものである。なお、本実施の形態の基本構成は、実施の形態１と同じなので異なる点を中心に説明する。また、実施の形態１と同じ構成には同じ符号を付してその説明を省略する。 (Embodiment 3)

本実施の形態においては、加熱容器４１の底面最外周近傍に接合凹部４２を複数個設け、非磁性金属材料からなる複数個の凸脚部４３を接合凹部４２に接合固定しているものである。なお、凸脚部４３と接合凹部４２との接合固定方法は、例えば、機械的かしめ、溶接、ネジ締めなど効果を損なわなければ便宜選ぶことができる。   In the present embodiment, a plurality of bonding recesses 42 are provided in the vicinity of the outermost periphery of the bottom surface of the heating vessel 41, and a plurality of convex leg portions 43 made of a nonmagnetic metal material are bonded and fixed to the bonding recesses 42. . The method for joining and fixing the convex leg 43 and the joint recess 42 can be selected for convenience as long as the effects such as mechanical caulking, welding, and screw tightening are not impaired.

このように、本実施の形態の構成により、加熱時に凸脚部４３は誘導加熱されず、プレート２７の温度上昇はさらに激減され、焦げ付き固着などの清掃しにくい汚れを防止することができる。   As described above, according to the configuration of the present embodiment, the convex leg portion 43 is not induction-heated during heating, and the temperature rise of the plate 27 is further drastically reduced.

（実施の形態４）

The same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

本実施の形態においては、加熱容器２１の凸脚部２３により形成された底面加熱部２２から加熱コイル２８の上面までのギャップ寸法５１（Ｇ）の距離は、加熱容器２１に最大３ｋＷ以下の電力を入力できるように、凸脚部２３の高さを設定した構成としている。   In the present embodiment, the distance of the gap dimension 51 (G) from the bottom surface heating part 22 formed by the convex leg part 23 of the heating container 21 to the top surface of the heating coil 28 is a power of 3 kW or less at the maximum in the heating container 21. So that the height of the convex leg portion 23 is set.

本実施の形態においては、使用者が最大３ｋＷ以下の所定の電力を自由に設定して、種々の調理に適した高火力が得られ、自己温度制御と過昇防止を精度よく実現できる。   In the present embodiment, the user can freely set a predetermined power of 3 kW or less at maximum to obtain a high heating power suitable for various cooking, and self-temperature control and prevention of overheating can be realized with high accuracy.

以上のように、本発明にかかる加熱調理器用加熱容器は、加熱調理器のプレートの防汚性能を向上するとともに、本体機器側の温度制御に依存することなく種々の調理に適した自己温度制御と過昇防止を精度よく実現できるものであるので、実施の形態で示した電磁調理器は勿論のこと、例えば、金属プレートにシーズヒーターをブレージングした電気調理器やラジェントヒーターを利用した電気調理器などにも適用でき、同様の効果を得ることができるものである。   As described above, the heating container for the heating cooker according to the present invention improves the antifouling performance of the plate of the heating cooker and is self-temperature control suitable for various cooking without depending on the temperature control on the main device side.
