Description

本発明はファミリーレストランやコンビニエンスストアー、その他の店舗で使う業務用の複合加熱調理機に関する。   The present invention relates to a commercial combined cooking device used in family restaurants, convenience stores, and other stores.

ファミリーレストランやコンビニエンスストアー、その他の飲食店では来客の要望に応じて、ハンバーグやステーキ、グラタン、シューマイ、ギョーザなどの各種被調理物を、即席的にすばやく加熱調理する必要がある。特許文献1にはそのための有用なコンベアオーブン/トースターが記載されている。   At family restaurants, convenience stores, and other restaurants, it is necessary to instantly and quickly cook various food items such as hamburgers, steaks, gratins, shumai, gyoza, etc. according to the demands of visitors. Patent Document 1 describes a useful conveyor oven / toaster for that purpose.

他方、通常のオーブン機能(天火焼き、焦げ目の付与)に加えて、被調理物を蒸気により焼いたり、蒸したりするスチームコンベクションオーブンは、例えば特許文献2〜6に広く開示されている。そのうち、特許文献5(特開2000−104924号公報)に記載のスチームコンベクションオーブンが、ヒーター(15)からの加熱により蒸気を発生するスチーム装置(17)と、熱風の強制循環用ファン(12)とを焼成室(7)内に装備している点で、本発明の複合加熱調理機と最も近似する公知技術であると考えられる。   On the other hand, in addition to a normal oven function (celestial baking, charring), a steam convection oven for baking or steaming an object to be cooked with steam is widely disclosed in, for example, Patent Documents 2 to 6. Among them, a steam convection oven described in Patent Document 5 (Japanese Patent Laid-Open No. 2000-104924) includes a steam device (17) that generates steam by heating from a heater (15), and a fan (12) for forced circulation of hot air. In the baking chamber (7), it is considered to be a publicly known technique that is most similar to the combined cooking device of the present invention.

特開平11−264550号公報JP 11-264550 A 特開平6−281147号公報JP-A-6-281147 特開平9−119642号公報JP-A-9-119642 特開平10−185200号公報JP-A-10-185200 特開2000−104924号公報JP 2000-104924 A 特開2007−57144号公報JP 2007-57144 A

ところが、上記公知技術の蒸気を発生するスチーム装置(17)は、給水用の内管(40)とこれを包囲する外管(41)並びにこれらの内外相互間に介挿された複数の蓄熱部材(丸鋼)(44)とから成り、極めて複雑・特殊な構造であるため、被焼成物を焼成する処理量との関係上、製造コストが余りにも高価となり過ぎる。   However, the steam device (17) for generating steam according to the above-mentioned known technique has a water supply inner pipe (40), an outer pipe (41) surrounding the inner pipe (40), and a plurality of heat storage members interposed between the inner and outer sides. (Round steel) (44), which is an extremely complicated and special structure, the manufacturing cost is too expensive due to the amount of processing for firing the object to be fired.

また、上記内管(40)の給水を加熱するためのヒーター(15)が、スチーム装置(17)とかなり離隔した片隅位置にあり、そのヒーター(15)の熱をたとえスチーム装置(17)の蓄熱部材(44)によって蓄熱し、その蓄熱により内管(40)の給水を加熱し、水蒸気又は熱湯として外管(41)の吐出孔(43)から、吸引開口(10)と熱風通路(11)へ吐出するとしても、「水蒸気とならなかった水もその温度は沸騰温度に近い温度となる」(公報の段落〔0041〕参照)と記載されているとおり、焼成室(7)の内部に100℃以上の過熱蒸気を生成することは不可能である。   Moreover, the heater (15) for heating the water supply of the said inner pipe (40) exists in the one corner position considerably separated from the steam apparatus (17), and even if the heat of the heater (15) of the steam apparatus (17) Heat is stored by the heat storage member (44), the water supply of the inner pipe (40) is heated by the heat storage, and from the discharge hole (43) of the outer pipe (41) as steam or hot water, the suction opening (10) and the hot air passage (11 As described in the paragraph [0041] of the publication, “water that has not become water vapor also has a temperature close to the boiling temperature” (see paragraph [0041] of the publication). It is impossible to produce superheated steam at 100 ° C. or higher.

更に、焼成室内を循環する熱風によって、被焼成物を焼成すると共に、その焼成室内へ蒸気も供給し得るようになっているが、その被焼成物がクッキーやフランスパンなどの製菓・製パン生地であればともかく、例えばハンバーグやステーキ、ギョーザ、その他の加熱皿と一緒に焼き上げ直後、その加熱皿に載せた状態のままで来客の食卓へ提供する被調理物の場合には、これを加熱皿と接触している下方(裏側)からもすばやく、その上方(表側)からとの全体的な均一温度に加熱調理することができず、業務用としての即応性や効率、利便性などに劣る。   In addition, the product to be baked can be baked by hot air circulating in the baking chamber, and steam can be supplied to the baking chamber. The material to be baked is made of confectionery and bread dough such as cookies and French bread. Whatever the case, for example, in the case of cooked food that is served on the customer's table immediately after being baked with hamburger, steak, gyoza, or other heated dishes, this is called a heated dish. It cannot be cooked quickly from the lower side (back side) in contact with the entire uniform temperature from the upper side (front side), resulting in poor responsiveness, efficiency and convenience for business use.

しかも、上記したような各種被調理物の内部に蒸気が封じ込められたシットリ感やジューシー感に富む仕上がり状態を得ることは不可能であり、このことは特許文献1(特開平11−264550号公報)に開示のコンベアオーブン/トースターについても、同様に言える。   In addition, it is impossible to obtain a finished state rich in a sense of sizzle and juiciness in which steam is contained in various cooked items as described above, which is disclosed in Japanese Patent Application Laid-Open No. 11-264550. The same applies to the conveyor oven / toaster disclosed in (1).

本発明はこのような課題の改良を目的としており、その目的を達成するために、請求項1では被調理物の加熱皿を下方から電磁誘導加熱する第1電磁誘導加熱器が内蔵された据付け台と、   SUMMARY OF THE INVENTION The present invention aims to improve such a problem, and in order to achieve the object, in claim 1, a first electromagnetic induction heater for electromagnetically heating a heating dish of a food to be cooked from below is installed. Stand,

その据付け台上へ固定状態に搭載された正面開閉扉付きの調理庫と、   A cooking cabinet with a front door that is fixedly mounted on the mounting base;

第2電磁誘導加熱器によって上方から電磁誘導加熱される加熱フィン付きの加熱板と、その加熱板の加熱フィンへ水を投射する1個又は複数のスプレーノズルとから成り、上記調理庫の天井面となるように設置された蒸気発生器と、   A heating plate with a heating fin that is electromagnetically heated from above by a second electromagnetic induction heater, and one or more spray nozzles that project water onto the heating fin of the heating plate, the ceiling surface of the cooking chamber A steam generator installed to be

その蒸気発生器の加熱フィンから発生する過熱蒸気を調理庫の内部全体へ拡散させるべく、その加熱フィンの下方位置に架設された多孔体の邪魔板と、   In order to diffuse the superheated steam generated from the heating fin of the steam generator to the entire interior of the cooking chamber, a baffle plate of a porous body erected at a position below the heating fin,

同じく過熱蒸気を調理庫の内部全体へ強制的に対流・循環させるべく、上記蒸気発生器の加熱フィンと上記邪魔板との上下相互間に介挿設置されたシロッコファンとを備え、   Similarly, in order to forcibly convection and circulate the superheated steam to the entire inside of the cooking chamber, the heating fin of the steam generator and a sirocco fan installed between the upper and lower sides of the baffle plate,

上記加熱皿に載せたハンバーグやステーキ、ギョーザ、シューマイなどの被調理物に対して、その下方から第1電磁誘導加熱器による伝導熱を与えると同時に、上方からシロッコファンにより上記過熱蒸気の対流熱を与えて加熱調理することを特徴とする。   The hamburger, steak, gyoza, shumai and other cooked items placed on the heating pan are given conduction heat by the first electromagnetic induction heater from below, and at the same time, the convection heat of the superheated steam is generated from above by a sirocco fan. It is characterized by heating and cooking.

また、請求項2では蒸気発生器の加熱板から多数の加熱フィンを、底面視の全体的な放射対称配列型又は平行配列型として一体的に垂下させる一方、   Further, in claim 2, a large number of heating fins are integrally suspended from the heating plate of the steam generator as an overall radial symmetric arrangement type or parallel arrangement type in a bottom view,

その加熱板の加熱フィンに向かうスプレーノズルが付属する給水管の1個又は複数を、調理庫の外部から導入配管すると共に、   While introducing one or more of the water supply pipes attached with the spray nozzles toward the heating fins of the heating plate from the outside of the cooking chamber,

その各給水管の途中に介挿設置した給水弁を、自動間歇的に開閉制御することを特徴とする。   The water supply valve inserted and installed in the middle of each water supply pipe is automatically and intermittently controlled to open and close.

請求項3では加熱皿の発熱温度をその加熱皿の底面と接触する温度センサーにより検知して、その出力電気信号に基き第1電磁誘導加熱器における励磁用高周波電源の加熱力を強弱調整することを特徴とする。   According to a third aspect of the invention, the heating temperature of the heating pan is detected by a temperature sensor in contact with the bottom surface of the heating pan, and the heating power of the excitation high-frequency power source in the first electromagnetic induction heater is adjusted based on the output electric signal. It is characterized by.

更に、請求項4では蒸気発生器における加熱フィンの加熱温度を非接触式温度センサーにより検知して、その出力電気信号に基き第2電磁誘導加熱器における励磁用高周波電源の加熱力を強弱調整することを特徴とする。   Further, in claim 4, the heating temperature of the heating fin in the steam generator is detected by a non-contact temperature sensor, and the heating power of the excitation high-frequency power source in the second electromagnetic induction heater is adjusted based on the output electric signal. It is characterized by that.

請求項1の上記構成によれば、ハンバーグやステーキ、ギョーザなどの被調理物が載置された状態にある加熱皿を、下方(裏側)から第1電磁誘導加熱器により発熱させ、その加熱皿からの伝導熱により上記被調理物の底面に適度な焦げ目が付くオーブン調理を行なえる。   According to the said structure of Claim 1, the heating pan in the state by which to-be-cooked objects, such as a hamburger, a steak, and a goose are placed, is heated with a 1st electromagnetic induction heater from the downward direction (back side), The heating pan Oven cooking can be performed in which the bottom surface of the object to be cooked is moderately burnt by the conduction heat from the oven.

しかも、このような加熱皿を下方(裏側)から電磁誘導加熱する作用との同時進行として、調理庫の天井面に内蔵設置された蒸気発生器から発生する過熱蒸気を、シロッコファンと邪魔板との働きにより、調理庫の内部全体に対流・循環させ、その過熱蒸気の温度ムラがない対流熱により、上記加熱皿に載っている被調理物を上方(表側)からも焼き上げ調理するようになっているため、被調理物毎の独特な風味や香り、水分(蒸気)が封じ込められたジューシー感と柔らかいボリューム感に富む加熱調理状態を、頗る短時間での熱効率良く得られるのであり、特にファミリーレストランやコンビニエンスストアーなどの飲食店にとって、著しく有益となる。   In addition, as a process of electromagnetic induction heating from the lower side (back side) of such a heating pan, the superheated steam generated from the steam generator built in the ceiling surface of the cooking chamber is converted into the sirocco fan and the baffle plate. Due to the function of convection and circulation through the entire interior of the cooking chamber, the food to be cooked on the heating pan is also baked from above (front side) by convection heat without uneven temperature of the superheated steam. Therefore, a unique flavor, aroma, and moisture (steam) for each food item can be obtained in a juicy and soft volume-enriched cooking state that can be cooked quickly and efficiently, especially in families. It will be significantly beneficial for restaurants and convenience stores.

また、上記蒸気発生器は調理庫の天井面となる関係状態に内蔵設置されており、その加熱板の加熱フィンが上方から第2電磁誘導加熱器により加熱され、その加熱された加熱フィンへ給水管のスプレーノズルにより水を投射して、調理庫内へ過熱蒸気を発生するようになっているため、例えば調理庫の外部に設置した貯水タンクをガスバーナーにより加熱して、その貯水から発生させた蒸気を、調理庫の内部へ導入配管するような構成に比して、その必要な設備を著しく簡素化できる効果もある。   Further, the steam generator is installed in a relational state that becomes the ceiling surface of the cooking chamber, and the heating fin of the heating plate is heated from above by the second electromagnetic induction heater, and water is supplied to the heated heating fin. Since water is projected by the spray nozzle of the pipe and superheated steam is generated in the cooking chamber, for example, a water storage tank installed outside the cooking chamber is heated by a gas burner and generated from that water storage. Compared to a configuration in which the steam is introduced into the inside of the cooking chamber, the necessary equipment can be remarkably simplified.

特に、請求項2の構成を採用するならば、蒸気発生器の加熱板から多数の加熱フィンが下方から見て、全体的な放射対称配列型又は平行配列型として一体的に垂下しているため、その加熱表面積の増大により、瞬時に多量の過熱蒸気を調理庫の内部へ発生させることができるほか、各給水管の給水弁は自動間歇的に開閉制御されて、その給水管のスプレーノズルから水を投射するようになっているため、調理庫内の目標温度をいたずらに低下させる如く、その加熱温度制御の妨げとなるおそれはなく、被調理物の大きさや種類などに対応しやすい効果もある。   In particular, if the configuration of claim 2 is employed, a large number of heating fins hang down integrally from the heating plate of the steam generator as viewed from below as an overall radial symmetric arrangement type or parallel arrangement type. By increasing the heating surface area, a large amount of superheated steam can be instantly generated inside the cooking chamber, and the water supply valves of each water supply pipe are automatically opened and closed and controlled from the spray nozzle of the water supply pipe. Since water is projected, there is no risk of hindering the heating temperature control as the target temperature in the cooking chamber is unnecessarily lowered, and there is also an effect that it is easy to respond to the size and type of the object to be cooked is there.

更に、請求項3の構成を採用するならば、加熱皿とこれに載置される被調理物の大きさや種類などに応じて、その加熱皿と延いては被調理物の加熱温度を高く又は低く調整することができ、被調理物の過度な焦げ付き不良を予防し得る効果がある。   Furthermore, if the structure of Claim 3 is employ | adopted, according to the magnitude | size, kind, etc. of a heating pan and the to-be-cooked object mounted on this, the heating temperature of the to-be-cooked object and the cooking object are made high or It can be adjusted to a low level, and there is an effect that can prevent an excessive burning failure of the object to be cooked.

他方、請求項4の構成を採用するならば、上記被調理物の大きさや種類などに応じて、調理庫内の目標温度を高く又は低く調整することができ、被調理物の希望する加熱調理状態を得られる効果がある。   On the other hand, if the structure of Claim 4 is employ | adopted, according to the magnitude | size, the kind, etc. of the said to-be-cooked object, the target temperature in a cooking chamber can be adjusted high or low, and the desired cooking by the to-be-cooked object There is an effect to obtain the state.

以下、図示の実施形態に基いて本発明の具体的構成を詳述すると、図1〜8は加熱皿(10)に載置したハンバーグやステーキ、シュウマイ、ギョーザなどの各種被調理物(M)に対して、蒸気発生器(S)により上方(表側)から供給される蒸気の対流熱と、第1電磁誘導加熱器(H1)により下方(裏側)から与えられる伝導熱とが同時作用する複合加熱調理機を示しており、これは作業床への据付け台(F)とその上面へ固定状態に搭載された調理庫(R)とを備え、ファミリーレストランやコンビニエンスストアーなどの飲食店にふさわしい大きさとして、例えば幅が約700mm×奥行が約720mm×高さが約1500mmである。   Hereinafter, based on the illustrated embodiment, the specific configuration of the present invention will be described in detail. FIGS. 1 to 8 show various cooked items (M) such as hamburger, steak, shumai, gyoza placed on a heating dish (10). In contrast, the convection heat of the steam supplied from above (front side) by the steam generator (S) and the conduction heat given from below (back side) by the first electromagnetic induction heater (H1) act simultaneously. This shows a cooking device, which has a mounting base (F) on the work floor and a cooking chamber (R) that is fixedly mounted on the top surface, and is suitable for restaurants such as family restaurants and convenience stores. For example, the width is about 700 mm × depth is about 720 mm × height is about 1500 mm.

先ず、上記複合加熱調理機の据付け台(F)は山形ステンレス鋼材から平面視の四角形に枠組み一体化されているが、その開口上面を有する限りでは、ステンレス鋼板から中空の竪型直方体(ボックス形態)に組み立てても良い。(11)はその据付け台(F)の角隅部に軸支されたブレーキ付きのキャスターであり、これによって据付け場所を変えることができる。(12)は上記据付け台(F)における枠内の中途高さ位置に架設された水平な仕切り板であり、その上面に第1電磁誘導加熱器(H1)の励磁用高周波電源(加熱用インバーター)(13)が搭載されている。   First, the mounting base (F) of the above-mentioned combined cooking device is integrated with a square shape in a plan view from an angle stainless steel material. However, as long as the upper surface of the opening is provided, a hollow bowl-shaped rectangular parallelepiped (box shape) is formed from a stainless steel plate. ) May be assembled. (11) is a caster with a brake that is pivotally supported at the corner of the mounting base (F), whereby the installation location can be changed. (12) is a horizontal partition plate installed at a midway height position in the frame of the mounting base (F), and an excitation high frequency power source (heating inverter) for the first electromagnetic induction heater (H1) is provided on the upper surface of the partition plate. ) (13) is mounted.

茲に、第1電磁誘導加熱器(H1)は図2、3や図7、8のような全体のユニット体として、1本物の銅線(リッツ線)から加熱皿(10)の大きさとほぼ対応する正方形や円形の渦巻き状態に周回された電磁誘導加熱コイル(14)と、その電磁誘導加熱コイル(14)における巻き径が比較的小さい中央加熱コイル部(14a)の中心を垂直に貫通する強磁性体の芯軸(15)と、同じく巻き径が比較的大きい周辺加熱コイル部(14b)を受け持つため、平面視の全体的な放射対称分布型に配列された複数のコイル受け杆(16)と、その複数のコイル受け杆(16)や1本の上記芯軸(15)を支持する共通の水平なベース板(17)とから成り、そのベース板(17)が調理庫(R)の底面周辺部から複数のハンガーボルト(18)と固定ナット(19)を介して、設置高さの調整自在(昇降自在)に吊り下げられている。但し、調理庫(R)の底面周辺部からベース板(17)を吊り下げる代りに、そのベース板(17)を上記据付け台(F)の水平な仕切り板(12)へ受け持ち固定させても勿論良い。   In addition, the first electromagnetic induction heater (H1) is an entire unit body as shown in FIGS. 2, 3, 7 and 8, and is approximately the size of a heating pan (10) from a single copper wire (Litz wire). The electromagnetic induction heating coil (14) circulated in a corresponding square or circular spiral state and the center of the central heating coil portion (14a) having a relatively small winding diameter in the electromagnetic induction heating coil (14) are vertically penetrated. Since it takes charge of the ferromagnetic core shaft (15) and the peripheral heating coil portion (14b) having a relatively large winding diameter, a plurality of coil receivers (16 ) And a common horizontal base plate (17) supporting the plurality of coil receiving bowls (16) and one core shaft (15), and the base plate (17) is a cooking chamber (R). Multiple hanger bolts (18 And fixed through a nut (19) is suspended freely adjust the installation height (vertically movably). However, instead of suspending the base plate (17) from the bottom peripheral portion of the cooking chamber (R), the base plate (17) may be supported and fixed to the horizontal partition plate (12) of the mounting base (F). Of course it is good.

そして、何れにしても上記第1電磁誘導加熱器(H1)の電磁誘導加熱コイル(14)や芯軸(15)は、調理庫(R)の底面中央部に確保された第1電磁誘導加熱器用逃し口(20)を通じて、その調理庫(R)内の加熱皿(10)を下方(裏側)から加熱する。更に言えば、電磁誘導加熱コイル(14)の中央加熱コイル部(14a)がその芯軸(15)による磁束の集中的な浸透作用とも相俟って、加熱皿(10)における対応的な底面中央部の加熱を分担する一方、同じく電磁誘導加熱コイル(14)の周辺加熱コイル部(14b)が加熱皿(10)における対応的な底面周辺部の加熱を分担して、その加熱皿(10)の底面全体と延いては被調理物(M)の底面全体をすばやく均一に加熱できるようになっている。   In any case, the electromagnetic induction heating coil (14) and the core shaft (15) of the first electromagnetic induction heater (H1) are first electromagnetic induction heating secured at the center of the bottom surface of the cooking chamber (R). The heating pan (10) in the cooking chamber (R) is heated from below (back side) through the dexterous escape opening (20). More specifically, the center heating coil portion (14a) of the electromagnetic induction heating coil (14) is coupled with the concentrated penetration of magnetic flux by the core shaft (15), and the corresponding bottom surface in the heating pan (10). While the central heating part is shared, the peripheral heating coil part (14b) of the electromagnetic induction heating coil (14) also shares the corresponding bottom peripheral part heating in the heating dish (10), and the heating dish (10 ) And the entire bottom surface of the object to be cooked (M) can be heated quickly and uniformly.

図示実施形態の加熱皿(10)は磁性体の鉄から成るが、そのフラットな底面へ鉄粉などの発熱皮膜(図示省略)を溶射することによって、導電性を与えても良く、その導電性を有する限りでは、上記加熱皿(10)の材質としてフェライト系ステンレス鋼や銅、鉄とアルミとのクラッド材、アルミとステンレスとのクラッド材などを採用することもできる。何れにしても、このような加熱皿(10)は被調理物(M)の調理でき次第、その被調理物(M)を載せたままで食卓へ提供されることになる。   Although the heating pan (10) of the illustrated embodiment is made of magnetic iron, it may be given conductivity by spraying a heat generating film (not shown) such as iron powder on its flat bottom surface. As long as it has, the ferritic stainless steel and copper, the clad material of iron and aluminum, the clad material of aluminum and stainless steel, etc. can also be employ | adopted as a material of the said heating pan (10). In any case, as soon as the cooking object (M) can be cooked, such a heating dish (10) is provided to the table with the cooking object (M) placed thereon.

また、上記磁性体の芯軸(15)は一定な太さを有する角柱形や円柱形のフェライトから成り、これに電磁誘導加熱コイル(14)の中央加熱コイル部(14a)が巻き付けらた状態にある。そのため、中央加熱コイル部(14a)を流れる高周波電流によって起生される磁束が、その芯軸(フェライトコアー)(15)から加熱皿(10)に浸透して、その加熱皿(10)の底面中央部を即座にロスなく加熱することができる。   Further, the core shaft (15) of the magnetic body is made of prismatic or cylindrical ferrite having a constant thickness, and the central heating coil portion (14a) of the electromagnetic induction heating coil (14) is wound around the core shaft (15). It is in. Therefore, the magnetic flux generated by the high-frequency current flowing through the central heating coil portion (14a) penetrates from the core shaft (ferrite core) (15) into the heating pan (10), and the bottom surface of the heating pan (10). The central part can be heated immediately without loss.

更に、上記コイル受け杆(16)は一定な太さのステンレス鋼棒やアルミ棒、その他の非磁性体の金属材から、図2、3のようなほぼ倒立L字形に折り曲げ立体化されており、その水平な腕杆部(16a)に上記電磁誘導加熱コイル(14)が受け持ち固定されていると共に、垂直の脚杆部(16b)が上記ベース板(17)へ固定ナット(21)を介して取り付けられている。その固定ナット(21)は上記ハンガーボルト(18)や固定ナット(19)と同じく、アルミやステンレス鋼などの非磁性体から成る。上記ベース板(17)は芯軸(15)から下方に向かう磁束の遮断用として、その磁束を反射できる非磁性体のアルミ板やステンレス鋼板などから成る。   Furthermore, the coil receiving rod (16) is three-dimensionally bent from a stainless steel rod, aluminum rod or other non-magnetic metal material having a constant thickness into a substantially inverted L shape as shown in FIGS.

上記のような業務用複合加熱調理機を運転して、来客が望む被調理物(例えばハンバーグ)(M)を加熱調理する場合について言えば、調理庫(R)の正面開閉扉(27)を開放して、被調理物(M)が載せられた状態にある加熱皿(10)を、その調理庫(R)内の底絶縁板(31)上へ挿入セットする。   In the case of operating the above-described combined heat cooking machine for business and cooking the food to be cooked (for example, hamburger) (M) desired by the customer, the front door (27) of the cooking chamber (R) is opened. The heating pan (10) in a state where it is opened and the object (M) is placed is inserted and set on the bottom insulating plate (31) in the cooking cabinet (R).

そして、上記加熱皿(10)の加熱源である第1電磁誘導加熱器(H1)の電磁誘導加熱コイル(14)へ、その励磁用高周波電源(13)から高周波電流を供給して、加熱皿(10)を下方(裏側)から発熱させ、その加熱皿(10)からの伝導熱により被調理物(M)を焼き上げ、被調理物(M)の底面に適度な焦げ目が付くオーブン調理を行なう。   Then, a high frequency current is supplied from the exciting high frequency power source (13) to the electromagnetic induction heating coil (14) of the first electromagnetic induction heater (H1), which is a heating source of the heating pan (10), and the heating pan is heated. (10) is heated from below (back side), the cooking object (M) is baked by the conduction heat from the heating dish (10), and oven cooking is performed in which the bottom of the cooking object (M) is moderately burnt. .

他方、このような下方(裏側)から行なうオーブン調理との同時進行として、調理庫(R)の天井面に蒸気発生器(S)を形作っている加熱板(34)の加熱フィン(34a)を、第2電磁誘導加熱器(H2)の電磁誘導加熱コイル(35)によってやはり加熱し、その加熱フィン(34a)へ給水管(42)のスプレーノズル(43)から自動間歇的に水を投射して、瞬時に大量の過熱蒸気を発生させる。   On the other hand, the heating fins (34a) of the heating plate (34) forming the steam generator (S) on the ceiling surface of the cooking chamber (R) as the simultaneous progress with the oven cooking performed from the lower side (back side). The second electromagnetic induction heater (H2) is also heated by the electromagnetic induction heating coil (35), and water is automatically and intermittently projected onto the heating fin (34a) from the spray nozzle (43) of the water supply pipe (42).
