Also, since electromagnetic induction heating of the pot 11 is performed by an induction heating coil 2, the pot 11 is excellently heated without being affected by a contact state with the mounting member 6 and there is no risk of the abnormal temperature rise of the mounting member 6. Also, the spilt stock is not immediately solidified on the upper surface of the mounting member 6 and cleanability as the cooker is improved in this view point as well. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

Translated fromJapanese

本発明は、主にコンビニエンスストアー（以下、ＣＶＳという）などに設置される加熱調理器に関する。  The present invention relates to a cooking device mainly installed in a convenience store (hereinafter referred to as CVS).

一般に、ＣＶＳなどで調理物を加熱して販売するための加熱調理器が、たとえば特許文献１などで知られている。この種の加熱調理器は、加熱手段を接合した載置部材に、容器を載せて加熱するとともに、温度検知部によって容器の温度を監視し、容器を加熱して販売を行なっている。
特開平１１−１８９４０号公報In general, for example,Patent Literature 1 discloses a cooking device for heating and selling a cooked product with CVS or the like. In this type of cooking device, the container is placed on the mounting member to which the heating means is joined and heated, and the temperature of the container is monitored by the temperature detection unit, and the container is heated for sale.
Japanese Patent Laid-Open No. 11-18940

しかし、上記構成の販売用の加熱調理器では、加熱手段を接合した載置部材を加熱し、熱伝導により容器を加熱する方式（ヒータ式）なので、載置部材と容器との接触状態により熱効率が左右され、容器の載置部材接触面に対する寸法精度が高く要求される。また、使用に伴ない容器の変形や汚れが発生したり、容器と載置部材との間に煮汁の蒸発残渣物などによる堆積や異物の挟み込みなどが発生したりすると、熱効率が極端に低下するだけでなく、容器の載置部材が異常に温度上昇して、加熱手段の断線や載置部材の変形などを引き起こす。  However, since the heating cooker for sale having the above configuration is a system (heater type) in which the mounting member to which the heating means is joined is heated and the container is heated by heat conduction (heater type), the thermal efficiency depends on the contact state between the mounting member and the container. Therefore, the dimensional accuracy with respect to the mounting member contact surface of the container is required to be high. In addition, if the container is deformed or soiled with use, or if there is an accumulation of boiled juice residue or foreign matter between the container and the mounting member, the thermal efficiency will be extremely reduced. In addition, the temperature of the mounting member of the container rises abnormally, causing disconnection of the heating means and deformation of the mounting member.

また、温度検知部は、所定の圧力で容器に接触して容器の温度を正確に検知するように付勢されており、容器からこぼれた煮汁が蒸発して固まると、当該温度検知部が動作不良になって、容器内の温度を正確に検知できない場合が多い。さらに、こぼれた煮汁は高温の載置部材やその周囲で固形分が固まり、長時間の使用によって汚れがこびり付いて、布で拭いても容易に取れなくなり、不衛生になる。そのため、使用中に容器から煮汁がこぼれても、容器の温度を正確に検出でき、汚れも簡単に清掃できる加熱調理器の出現が望まれていた。  In addition, the temperature detection unit is urged to contact the container at a predetermined pressure and accurately detect the temperature of the container. When the spilled spilled liquid evaporates and solidifies, the temperature detection unit operates. In many cases, it becomes defective and the temperature inside the container cannot be accurately detected. Further, the spilled boiled juice solidifies at the high temperature of the mounting member and its surroundings, and the dirt sticks to it when used for a long time. For this reason, there has been a demand for the appearance of a heating cooker that can accurately detect the temperature of the container and easily clean the dirt even if the broth spills from the container during use.

また、特に近年は加熱調理器としての省エネルギー化が求められているが、従来のような容器の周囲に設けられた枠体や、容器を覆う蓋であると、容器内で加熱された被調理物が直ぐに冷えてしまい、そのような要求に十分応えることができなかった。  Moreover, especially in recent years, energy saving as a heating cooker has been demanded. However, in the case of a frame provided around a conventional container or a lid that covers the container, cooking to be cooked in the container is performed. Things quickly cooled down and could not fully meet such demands.

本発明は上記問題点に鑑み、載置部材の異常な温度上昇を防止し、加熱効率を良好に維持すると共に、容器からこぼれた煮汁などの清掃が容易な加熱調理器を提供することを、その第１の目的とする。  In view of the above problems, the present invention provides a cooking device that prevents an abnormal temperature rise of the mounting member, maintains a good heating efficiency, and is easy to clean such as spilled broth from a container.

以下、本発明におけるおでん販売用の加熱調理器の一実施例について、添付図面を参照しながら説明する。加熱調理器の全体図を表わした図１〜図３において、１は本体の外郭をなす箱型の架台、２は磁束を発生するコイルである電磁誘導コイルで、この電磁誘導コイル２は架台１の上面に設けた耐熱樹脂製のコイルベース３に支持される。また、４は前記架台１の外周を覆うようにして設けられた耐熱樹脂製の上ケースであり、この上ケース４に前記コイルベース３が取付けられている。上ケース４の中央部には、前記電磁誘導コイル２やコイルベース３が配置され、この上ケース４の中央開口を覆うように、平板状の天板５が設けられる。そして、この上ケース４と天板５とにより、後述する鍋１１が載る載置部材６を構成する。  Hereinafter, an embodiment of a heating cooker for selling oden according to the present invention will be described with reference to the accompanying drawings. In FIG. 1 to FIG. 3 showing an overall view of the heating cooker, 1 is a box-shaped pedestal that forms the outer shell of the main body, 2 is an electromagnetic induction coil that is a coil for generating magnetic flux, and thiselectromagnetic induction coil 2 is apedestal 1 Is supported by acoil base 3 made of a heat-resistant resin provided on the upper surface. Reference numeral 4 denotes an upper case made of a heat-resistant resin provided so as to cover the outer periphery of thegantry 1, and thecoil base 3 is attached to the upper case 4. Theelectromagnetic induction coil 2 and thecoil base 3 are arranged at the center of the upper case 4, and aflat top plate 5 is provided so as to cover the central opening of the upper case 4. The upper case 4 and thetop plate 5 constitute amounting member 6 on which apan 11 described later is placed.

鍋１１は、電磁特性がよく、且つ耐腐食性を向上させたフェライト系ステンレスからなり、おでんの具やだし汁などの被調理物を何時でも出し入れできるように、上部を開口した有底状に形成される。また、鍋１１の底面には、外方に突出したエンボス１２が複数形成される。これらの各エンボス１２は、何れも前記載置部材６の上面に形成した凹凸のない平坦面６Ａに当接するようになっている。さらに１３は、電磁誘導コイル２の下側に配設されたフェライトコアであり、当該フェライトコア１３は電磁誘導コイル２から発生する磁束を整え、磁束を鍋１１に有効に伝えるためのものである。  Thepan 11 is made of ferritic stainless steel with good electromagnetic characteristics and improved corrosion resistance, and is formed in a bottomed shape with an open top so that cooking objects such as oden utensils and soup stock can be taken in and out at any time. Is done. A plurality ofembosses 12 projecting outward are formed on the bottom surface of thepan 11. Each of theseembosses 12 comes into contact with aflat surface 6A having no irregularities formed on the upper surface of themounting member 6 described above. Further, 13 is a ferrite core disposed on the lower side of theelectromagnetic induction coil 2, and theferrite core 13 is for adjusting the magnetic flux generated from theelectromagnetic induction coil 2 and effectively transmitting the magnetic flux to thepan 11. .

１５は、鍋１１の底面に当接するように、前記上ケース４の上面から突出して設けた感熱部である。この感熱部１５は、載置部材６の上面に突部として形成されたもので、感熱部１５の高さ方向の寸法は、前記エンボス１２の高さ寸法と同じく、載置部材６の平坦面６Ａを基準として例えば２ｍｍに形成される。載置部材６に設けられた温度センサ１６は、鍋１１の温度を精度よく検出するために、弾性部材であるバネ１７により感熱部１５の下面に常時押し当てられている。そして、感熱部１５は前記鍋１１に設けられたエンボス１２と共に、お互いが突き合わないように三点で鍋１１を支持しており（図３参照）、これにより載置部材６の実質的な上面である平坦面６Ａと鍋１１の底面との間に、所定の隙間が形成される。  Reference numeral 15 denotes a heat-sensitive portion provided so as to protrude from the upper surface of the upper case 4 so as to contact the bottom surface of thepan 11. The heat-sensitive part 15 is formed as a protrusion on the upper surface of themounting member 6, and the dimension of the heat-sensitive part 15 in the height direction is the same as the height of theemboss 12 and the flat surface of themounting member 6. For example, it is 2 mm with 6A as a reference. Thetemperature sensor 16 provided on themounting member 6 is constantly pressed against the lower surface of the heat-sensitive part 15 by aspring 17 that is an elastic member in order to detect the temperature of thepan 11 with high accuracy. And the heatsensitive part 15 is supporting thepan 11 by three points so that it may not mutually face | match with theemboss 12 provided in the said pan 11 (refer FIG. 3), and, thereby, the substantial of themounting member 6 is carried out. A predetermined gap is formed between theflat surface 6 </ b> A that is the upper surface and the bottom surface of thepan 11.

なお、エンボス１２と感熱部１５は、図３に示すような位置関係に限定されるものではない。例えば、図４に示すように、矩形状をなす鍋１１の底面の四隅に、脚としてのエンボス１２をそれぞれ配設すると共に、感熱部１５の上面を載置部材６の上面と面一になるように（つまり、感熱部１５の上面を載置部材６の平坦面６Ａから突出させないように）、エンボス１２に臨んで感熱部１５を配置する。こうすることで、鍋１１はエンボス１２で載置部材６の平坦面６Ａ上に支持され、且つ鍋１１の底部から突出したエンボス１２が感熱部１５に直接接することで、温度センサ１６により鍋１１の温度を精度よく検出することができる。  In addition, theembossing 12 and the heatsensitive part 15 are not limited to the positional relationship as shown in FIG. For example, as shown in FIG. 4, embosses 12 as legs are disposed at the four corners of the bottom surface of therectangular pan 11, and the upper surface of the heatsensitive portion 15 is flush with the upper surface of themounting member 6. As described above (that is, the upper surface of the heatsensitive portion 15 is not protruded from theflat surface 6A of the mounting member 6), the heatsensitive portion 15 is arranged facing theemboss 12. By doing so, thepan 11 is supported on theflat surface 6A of themounting member 6 by theemboss 12 and theemboss 12 protruding from the bottom of thepan 11 is in direct contact with the heatsensitive portion 15, so that thepan 11 is moved by thetemperature sensor 16. Can be detected with high accuracy.

前記感熱部１５は、図３および図４の何れの場合においても、従来のようにばねなどの弾性部材で鍋１１に押し当てられて上下動する構造ではなく、感熱部１５そのものが動かないように、載置部材６を構成する上ケース４に取付け固定される。このように、感熱部１５が可動しない構造であると、感熱部１５と上ケース４との隙間にシール材（図示せず）を充填することができ、万一樹脂製のカバーが破損したり、取付けなかったりした場合でも、煮汁などが隙間から侵入しないようになっている。  3 and 4, the heatsensitive portion 15 is not structured to move up and down by being pressed against thepan 11 by an elastic member such as a spring as in the prior art, so that the heatsensitive portion 15 itself does not move. In addition, it is attached and fixed to the upper case 4 constituting the mountingmember 6. Thus, if the heatsensitive part 15 has a structure that does not move, the gap between the heatsensitive part 15 and the upper case 4 can be filled with a sealing material (not shown), and the resin cover should be damaged. Even if it is not attached, boiled juice does not enter through the gap.

架台１の内部には、電磁誘導コイル２に供給する高周波電流を供給するためのＩＨ（電磁誘導加熱）制御回路２１と、このＩＨ制御回路２１を構成する発熱部品としての制御素子を冷却するための放熱器２２と、放熱器２２から放出される熱を架台１の外部に放出する冷却用ファン２３が各々設けられる。また、架台１の正面側には、操作および表示のための操作パネル２５（図２参照）が設けられる。そして、ＩＨ制御回路２１から高周波電流が電磁誘導コイル２に供給されると、電磁誘導コイル２から発生する磁界によって鍋１１が自己発熱して、鍋１１内に収容した被調理物の煮込みや保温の各行程を実行する。その際、課鍋11内の温度を制御する制御手段としてのＩＨ制御回路２１は、内蔵するプログラムシーケンスにより、被調理物であるおでんの煮込みが終了すると、自動的に保温に切り替わるように構成されている。  In thegantry 1, an IH (electromagnetic induction heating)control circuit 21 for supplying a high-frequency current to be supplied to theelectromagnetic induction coil 2 and a control element as a heat generating component constituting theIH control circuit 21 are cooled. And a coolingfan 23 for releasing heat released from theradiator 22 to the outside of thegantry 1 are provided. An operation panel 25 (see FIG. 2) for operation and display is provided on the front side of thegantry 1. When a high-frequency current is supplied from theIH control circuit 21 to theelectromagnetic induction coil 2, thepan 11 self-heats due to the magnetic field generated from theelectromagnetic induction coil 2, and the food to be cooked or kept warm is stored in thepan 11. Perform each of the steps. At that time, theIH control circuit 21 serving as a control means for controlling the temperature in thepot 11 is configured to automatically switch to heat insulation when the cooking of the oden, which is the object to be cooked, is completed by the built-in program sequence. ing.

加熱調理器の正面図を示す図２において、操作パネル２５は、電源プラグ（図示せず）が差し込まれるコンセントからの商用電源を投入または遮断する電源スイッチ２７と、前記温度センサ１６で検出した鍋１１の温度を表示したり、ＩＨ制御回路２１が異常と判断した時に、どのような異常であるのかをエラー状態として表示したりするＬＣＤ表示部２８と、制御中の行程を点灯す表示するランプ表示部２９と、を備えて構成される。なお、表示手段としてのＬＣＤ表示部２８やランプ表示部２９は、ＬＣＤやランプ以外の各種表示器を用いてもよい。  In FIG. 2 showing a front view of the heating cooker, theoperation panel 25 includes apower switch 27 for turning on / off commercial power from an outlet into which a power plug (not shown) is inserted, and a pan detected by thetemperature sensor 16. 11 and theLCD display unit 28 for displaying an abnormal state as an error state when theIH control circuit 21 determines that it is abnormal, and a lamp for displaying the process being controlled. And adisplay unit 29. TheLCD display unit 28 and thelamp display unit 29 as display means may use various displays other than the LCD and the lamp.

再度図１に戻り、本実施例における加熱調理器は、載置部材６に載置された鍋１１の上面開口に、取手３１付きの着脱自在な蓋３２が設けられると共に、鍋１１の側面全周を囲うように、枠体である木枠３３が設けられる。これらの蓋３２や木枠３３は、食品衛生法で適法範囲内にある樹脂製でもよいが、ここでは木製のものを使用している。また、蓋３２や木枠３３の内部には、鍋１１からの熱の逃げを抑制するために、発泡ウレタンなどの断熱材３４が配設される。特に鍋１１からの熱の逃げを効果的に防止するには、グラスウールなどの芯材をシート材の内部に圧縮真空状態で収容してなる真空断熱パネルを、こうした断熱材３４として用いるのが好ましい。  Returning to FIG. 1 again, the cooking device according to the present embodiment is provided with adetachable lid 32 with ahandle 31 at the top opening of thepan 11 placed on the placingmember 6, and the entire side surface of thepan 11. Awooden frame 33 that is a frame is provided so as to surround the circumference. Thelid 32 and thewooden frame 33 may be made of a resin that is within a legal range in the Food Sanitation Law, but here, a wooden one is used. Further, in order to suppress the escape of heat from thepot 11, aheat insulating material 34 such as urethane foam is disposed inside thelid 32 and thewooden frame 33. In particular, in order to effectively prevent the escape of heat from thepan 11, it is preferable to use as the heat insulating material 34 a vacuum heat insulating panel in which a core material such as glass wool is accommodated inside the sheet material in a compressed vacuum state. .

上記構成において、鍋１１を載置部材６の上面に載せると、鍋１１の底面に形成したエンボス１２が載置部材６の平坦面６Ａ上に当接すると共に、このエンボス１２を設けていない鍋１１の底面の部分に、載置部材６の平坦面６Ａから突出した感熱部１５が当接して、鍋１１が若干の隙間を有した状態で、載置部材６の上面に支持される。この状態で、おでんの具やだし汁などの被調理物を鍋１１の上面開口から投入し、蓋３２を鍋１１の上面に載せて、電源スイッチ２７を押動操作すると、ＩＨ制御回路２１に予め組み込まれた制御シーケンスにしたがって、鍋１１内の温度を温度センサ１６からの検出信号に基づき監視しながら、電磁誘導コイル２の駆動を制御し、煮込みから保温に至る一連の加熱行程を実行する。  In the above configuration, when thepan 11 is placed on the top surface of the mountingmember 6, the emboss 12 formed on the bottom surface of thepan 11 abuts on theflat surface 6 </ b> A of the mountingmember 6, and thepan 11 not provided with thisemboss 12. The heat-sensitive portion 15 protruding from theflat surface 6A of the mountingmember 6 is in contact with the bottom surface portion of the mountingmember 6, and thepan 11 is supported on the upper surface of the mountingmember 6 with a slight gap. In this state, to-be-cooked materials such as oden meal and soup stock are put in from the top opening of thepan 11, thelid 32 is placed on the top surface of thepan 11, and thepower switch 27 is pushed and operated. While monitoring the temperature in thepan 11 based on the detection signal from thetemperature sensor 16 according to the incorporated control sequence, the driving of theelectromagnetic induction coil 2 is controlled, and a series of heating steps from boiling to heat retention is executed.

このような加熱行程の途中で、例えば鍋１１から煮汁がこぼれたりすると、この煮汁は載置部材６の上面へと流れ落ちる。しかし、載置部材６の上面は感熱部１５を除いて平坦で、しかもこの感熱部１５は、載置部材６の平坦面６Ａよりエンボス１２と同じ高さ寸法程度の僅かにしか突出していないので、感熱部１５周辺に煮汁が残ることなく、布巾などで加熱部材６の上面全体をスムーズにまんべんなく清掃することができる。また、加熱手段である電磁誘導コイル２は、当該電磁誘導コイル２から発生する交番磁界によって鍋１１を直接加熱するものなので、載置部材６が直接加熱されず、また、鍋１１と載置部材６との間には隙間が形成されていて、鍋１１からの熱が載置部材６全体に極力伝わらないようになっているので、載置部材６の上面に流れ落ちた煮汁が固形化するのを防止して、汚れを拭き取り易くすることができる。  If the broth spills from thepan 11 during the heating process, for example, the broth flows down to the upper surface of the mountingmember 6. However, the upper surface of the mountingmember 6 is flat except for the heatsensitive portion 15, and the heatsensitive portion 15 protrudes slightly from theflat surface 6 </ b> A of the mountingmember 6 to the same height as theemboss 12. The entire upper surface of theheating member 6 can be smoothly and evenly cleaned with a cloth or the like without leaving any broth in the vicinity of the heatsensitive part 15. Moreover, since theelectromagnetic induction coil 2 which is a heating means heats thepan 11 directly by the alternating magnetic field generated from theelectromagnetic induction coil 2, the mountingmember 6 is not directly heated, and thepan 11 and the mounting member Since a gap is formed between thepan 6 and the heat from thepan 11 is prevented from being transmitted to the entire mountingmember 6 as much as possible, the broth that has flowed down to the upper surface of the mountingmember 6 is solidified. Can be prevented and dirt can be easily wiped off.

また、鍋１１内の煮込みや保温中には、鍋１１の側面から発生する熱が、木枠３３の内部に設けた断熱材３４によって封じ込められると共に、鍋１１の上面から発生する熱も、蓋体３２の内部に設けた別な断熱材３４によって封じ込められ、鍋１１全体の断熱性を維持することができる。この場合、断熱材としてより高性能な真空断熱パネルを使用することにより、顕著な断熱効果が得られ、加熱保温器として省エネルギー性を向上させることが可能になる。  Further, during the cooking and heat insulation in thepan 11, the heat generated from the side surface of thepan 11 is contained by theheat insulating material 34 provided inside thewooden frame 33, and the heat generated from the top surface of thepan 11 is also covered with the lid. It is contained by anotherheat insulating material 34 provided inside thebody 32, and the heat insulating property of theentire pan 11 can be maintained. In this case, by using a higher-performance vacuum heat insulating panel as the heat insulating material, a remarkable heat insulating effect can be obtained, and it becomes possible to improve the energy saving property as the heating and warming device.

以上のように、本実施例では、被調理物を収容する容器としての鍋１１と、鍋１１を載置する載置部材６と、鍋１１の蓋３２と、鍋１１の周りにある木枠３３と、加熱手段としての電磁誘導コイル２とを備え、電磁誘導コイル２からの交番磁界により鍋１１を電磁誘導加熱する構成とし、鍋１１の底面に載置部材６の上面に当接可能な脚すなわちエンボス１２を、エンボス加工を施すことにより形成している。  As described above, in this embodiment, thepan 11 as a container for storing the cooking object, the placingmember 6 for placing thepan 11, thelid 32 of thepan 11, and the wooden frame around thepan 11. 33 and theelectromagnetic induction coil 2 as a heating means, and thepan 11 is electromagnetically heated by an alternating magnetic field from theelectromagnetic induction coil 2 and can contact the top surface of the mountingmember 6 on the bottom surface of thepan 11. The leg, that is, theemboss 12 is formed by embossing.

このようにすると、鍋１１を安定に載せるための突部を載置部材６に設けるのではなく、鍋１１に脚としてのエンボス１２を形成するので、載置部材６の上面を可及的に平坦状にすることができる。これにより、鍋１１から煮汁などがこぼれても、載置部材６の上面を隅々まで容易に清掃ができる。また、鍋１１を電磁誘導コイル２で電磁誘導加熱するので、鍋１１の変形や汚れが生じた場合でも、載置部材６との接触状態に左右されず、鍋１１を良好に加熱できると共に、従来のように載置部材６をヒータで直接加熱する必要がなく、載置部材６が異常に温度上昇する虞れもない。しかも、こぼれた煮汁が載置部材６の上面で直ぐに固まったりしないので、この点でも加熱調理器しての清掃性が向上する。  If it does in this way, since the emboss 12 as a leg is formed in thepan 11 rather than providing the mountingmember 6 with the protrusion for mounting thepan 11 stably, the upper surface of the mountingmember 6 is made as much as possible. It can be made flat. Thereby, even if boiled soup spills from thepot 11, the upper surface of the mountingmember 6 can be easily cleaned to every corner. Moreover, since thepan 11 is electromagnetically heated by theelectromagnetic induction coil 2, even when thepan 11 is deformed or dirty, thepan 11 can be satisfactorily heated without being influenced by the contact state with the mountingmember 6, There is no need to directly heat the mountingmember 6 with a heater as in the prior art, and there is no possibility that the mountingmember 6 will rise abnormally. And since the spilled broth does not harden immediately on the upper surface of the mountingmember 6, the cleaning property as a heating cooker also improves in this respect.

また本実施例では、前記載置部材６に鍋１１の温度を検出するための検出部としての温度センサ１６を設けている。この場合、載置部材６の上面の清掃性が上述の理由により向上しているので、載置部材６に温度センサ１６を設けた場合に、こぼれた煮汁を直ぐに拭き取って、鍋１１に対する温度制御を正確に行なうことができる。  In the present embodiment, the mountingmember 6 is provided with atemperature sensor 16 as a detecting unit for detecting the temperature of thepan 11. In this case, since the cleanability of the upper surface of the mountingmember 6 is improved for the above-described reason, when thetemperature sensor 16 is provided on the mountingmember 6, the spilled broth is immediately wiped off, and the temperature control for thepan 11 is performed. Can be performed accurately.

この場合、載置部材６の上面に形成した段差状の突部たる感熱部１５に、温度センサ１６を配置してもよい。温度センサ１６を配置した感熱部１５が鍋１１に向けて突出しているので、鍋１１の温度を精度よく検出できると共に、感熱部１５を除く載置部材６の上面を平坦に形成でき、この載置部材６の上面にこぼれた煮汁などを極力残さずに拭き取ることができる。  In this case, thetemperature sensor 16 may be disposed on the heat-sensitive part 15 that is a stepped protrusion formed on the upper surface of the mountingmember 6. Since the heatsensitive part 15 in which thetemperature sensor 16 is arranged protrudes toward thepan 11, the temperature of thepan 11 can be detected with high accuracy, and the upper surface of the mountingmember 6 excluding the heatsensitive part 15 can be formed flat. The soup spilled on the upper surface of the mountingmember 6 can be wiped off without leaving as much as possible.

また代わりとして、別な変形例で説明したように、載置部材６の所定面である上面全体を平坦に形成し、この載置部材６の上面の一部に温度センサ１６が当接する感熱部１５を設けてもよい。こうすると、載置部材６の上面に温度センサ１６を配置するための段差部や突部が設けられておらず、その所定面である全体を平坦に形成しているので、載置部材６の上面にこぼれた煮汁などを残さずに、極めて容易に拭き取ることが可能になる。  Alternatively, as described in another modification, the entire upper surface, which is a predetermined surface of the mountingmember 6, is formed flat, and thetemperature sensor 16 contacts the part of the upper surface of the mountingmember 6. 15 may be provided. In this case, the stepped portion and the protrusion for arranging thetemperature sensor 16 are not provided on the upper surface of the mountingmember 6, and the entire predetermined surface is formed flat. It is possible to wipe off very easily without leaving any spilled soup on the upper surface.

また本実施例では、鍋１１の上面開口を覆う蓋３２に断熱材３４を設けている。鍋１１を覆う蓋３２に断熱材３４を設けることで、鍋１１から蓋３２を通しての熱の逃げを抑制して、省エネルギー効果を高めることが可能になる。そして好ましくは、蓋３２に設けた断熱材３４を、極めて断熱効果の高い真空断熱パネルのような真空断熱材で構成することで、鍋１１から蓋３２を通しての熱の逃げを極力防止することが可能になる。  In this embodiment, aheat insulating material 34 is provided on thelid 32 that covers the upper surface opening of thepan 11. By providing theheat insulating material 34 on thelid 32 that covers thepan 11, it is possible to suppress the escape of heat from thepan 11 through thelid 32, thereby enhancing the energy saving effect. And preferably, theheat insulating material 34 provided on thelid 32 is made of a vacuum heat insulating material such as a vacuum heat insulating panel having a very high heat insulating effect, thereby preventing heat escape from thepan 11 through thelid 32 as much as possible. It becomes possible.

また本実施例では、鍋１１と、鍋１１を載置する載置部材６と、鍋１１の周囲に設けられた木枠３３と、鍋１１を電磁誘導加熱する加熱手段としての電磁誘導コイルとを備え、木枠３３に断熱材３４を設けている。こうすると、鍋１１の周囲にある木枠３３に断熱材３４を設けることで、従来からの木枠３３を用いつつ、鍋１１から木枠３３を通しての熱の逃げを抑制して、省エネルギー効果を高めることが可能になる。  Moreover, in a present Example, thepan 11, the mountingmember 6 which mounts thepan 11, thewooden frame 33 provided in the circumference | surroundings of thepan 11, and the electromagnetic induction coil as a heating means which electromagnetically heats thepan 11; And aheat insulating material 34 is provided on thewooden frame 33. In this way, by providing theheat insulating material 34 on thewooden frame 33 around thepan 11, while using the conventionalwooden frame 33, heat escape from thepan 11 through thewooden frame 33 is suppressed, and an energy saving effect is achieved. It becomes possible to increase.

そして好ましくは、木枠３３に設けた断熱材３４を、極めて断熱効果の高い真空断熱パネルのような真空断熱材で構成することで、鍋１１から木枠３３を通しての熱の逃げを極力防止することが可能になる。  And preferably, theheat insulating material 34 provided on thewooden frame 33 is made of a vacuum heat insulating material such as a vacuum heat insulating panel having a very high heat insulating effect, thereby preventing the escape of heat from thepan 11 through thewooden frame 33 as much as possible. It becomes possible.
