Description

本発明は、調理庫内に収納された食品を加熱調理するために少なくとも誘導加熱手段を備える加熱調理装置に関する。   The present invention relates to a cooking device that includes at least induction heating means for cooking food stored in a cooking cabinet.

電子レンジはマイクロ波により食品を直接高周波加熱するため、温め加熱などの高速調理には非常に効果を発揮するものの、食品に焦げ目を付けることができず、焦げ目付け調理には不向きであった。一方、近年普及が進んでいる誘導加熱（ＩＨ）調理器は誘導加熱により磁性金属製の鍋などを加熱して調理を行うため、焦げ目付け調理や煮炊き調理などに最適である。そこで、上記のような高周波加熱による加熱調理の欠点を補うために、高周波加熱調理と誘導加熱調理とを併用した複合型の加熱調理装置が従来より知られている。   Microwave ovens directly heat high-frequency foods using microwaves, so they are very effective for high-speed cooking such as warming, but they cannot burn foods and are not suitable for scorched cooking. On the other hand, induction heating (IH) cookers, which have been popularized in recent years, are ideal for cooking by cooking or cooking for cooking by heating a magnetic metal pan or the like by induction heating. Therefore, in order to make up for the drawbacks of cooking by high-frequency heating as described above, a composite-type cooking device using both high-frequency cooking and induction cooking has been known.

例えば特許文献１に記載の加熱調理装置では、略箱形状の調理庫の底面の下方に誘導加熱コイルが配置され、該コイルから発生した磁束により調理庫底面上に載置された調理皿を誘導加熱することができるようになっている。他方、調理庫の後方にはマグネトロンが配置され、該マグネトロンから発生したマイクロ波が調理庫上面に形成された給電口を経て調理庫内に供給され、それによって調理皿上に置かれた食品を高周波加熱することができるようになっている。この種の加熱調理装置は、誘導加熱可能な構成の鍋やフライパンなどの容器内に収容された食品に対し、焦げ目付け調理や煮込み調理を行うのに好適である。   For example, in the heating and cooking apparatus described in Patent Document 1, an induction heating coil is disposed below the bottom surface of a substantially box-shaped cooking chamber, and a cooking dish placed on the bottom surface of the cooking chamber is guided by the magnetic flux generated from the coil. It can be heated. On the other hand, a magnetron is arranged behind the cooking chamber, and microwaves generated from the magnetron are supplied into the cooking chamber through a power supply port formed on the upper surface of the cooking chamber, and thereby the food placed on the cooking pan is removed. High frequency heating can be performed. This type of heating cooking apparatus is suitable for performing burnt-eye cooking or stew cooking on foods stored in a container such as a pan or a frying pan having a configuration capable of induction heating.

上記のような複合型加熱調理装置では、調理庫内から外部へのマイクロ波の漏洩を防止する必要がある一方、誘導加熱コイルから発生する磁束ができるだけ少ない損失で以て調理庫内に入り加熱対象である鍋などを貫通するようにする必要がある。そのため、調理庫の底壁面は多数の小孔が穿設されたパンチング板で構成され、その上に、低損失の誘電体から成る平板状の載置板が設置される構成となっている。パンチング板はマイクロ波を遮断する一方、磁束を高い効率で通過させ、また載置台はマイクロ波を吸収しにくく且つ磁束が貫通しても誘導加熱されないので、載置台上に載せられた被加熱物を良好にマイクロ波加熱及び誘導加熱することができる。   In the combined cooking device as described above, it is necessary to prevent microwave leakage from the inside of the cooking chamber, while the magnetic flux generated from the induction heating coil enters the cooking chamber with as little loss as possible and heats it. It is necessary to penetrate the target pot. Therefore, the bottom wall surface of the cooking chamber is configured by a punching plate having a large number of small holes, and a flat plate-shaped mounting plate made of a low-loss dielectric is installed thereon. The punching plate cuts off the microwave while allowing the magnetic flux to pass with high efficiency, and the mounting table is difficult to absorb the microwave and is not induction-heated even if the magnetic flux penetrates, so the object to be heated placed on the mounting table Can be satisfactorily heated by microwave and induction.

しかしながら、パンチング板は誘導加熱されにくいものの、その板金部分を貫通する一部の磁束の作用により若干は加熱される。また、誘導加熱コイル自体の温度上昇や載置台を経た鍋からの熱伝導による影響でもパンチング板の温度が上昇する。パンチング板は多数の小孔が形成されているために比較的剛性が低く、上述したような温度上昇によって高温になると、熱膨張によって反りが生じ易い。パンチング板が反ると様々な不具合が起こる。   However, the punching plate is hardly heated by induction, but is slightly heated by the action of a part of the magnetic flux penetrating the sheet metal portion. Further, the temperature of the punching plate also rises due to the temperature rise of the induction heating coil itself and the effect of heat conduction from the pan through the mounting table. Since the punching plate has a large number of small holes, the punching plate is relatively low in rigidity. When the punching plate is heated to a high temperature as described above, it is likely to warp due to thermal expansion. When the punching board is warped, various problems occur.

（１）パンチング板が反るとパンチング板と載置台上の鍋下面との距離が変化し、誘導加熱の効率が低下するおそれがある。
（２）パンチング板が加熱・冷却によって反ったり元に戻ったりを繰り返すと破れを生じ易く、耐久性の点で問題が生じる。
（３）初期的に載置台の下面とパンチング板との間に適度な空隙が形成されていても、熱膨張によってパンチング板が上に反って載置台に接触してしまうと載置台自体がかなりの高温になる。一般に載置台に用いられるセラミック等は高温で誘電損失が大きくなる特性を持つため、上記のような熱伝導によって載置台の誘電損失が大きくなり、マイクロ波を吸収し易くなるために被加熱物に対するマイクロ波加熱の効率が落ちてしまう。 (1) When the punching plate is warped, the distance between the punching plate and the bottom surface of the pan on the mounting table changes, and the efficiency of induction heating may be reduced.
(2) If the punching plate is repeatedly warped or returned to its original state by heating / cooling, the punching plate is likely to be broken and a problem arises in terms of durability.
(3) Even if an appropriate gap is initially formed between the lower surface of the mounting table and the punching plate, if the punching plate warps upward and contacts the mounting table due to thermal expansion, the mounting table itself is considerably It becomes high temperature. In general, ceramics and the like used for the mounting table have characteristics that the dielectric loss increases at a high temperature. Therefore, the dielectric loss of the mounting table increases due to the heat conduction as described above, and it is easy to absorb microwaves. The efficiency of microwave heating is reduced.

また、上記のような複合型加熱調理装置は、マイクロ波加熱と誘導加熱とを併用することで、例えばハンバーグ、餃子など、食品に適度なコゲ目を付けながらその食品内部まで加熱するような料理に向いており、特に業務用途で短時間に調理が必要な場合に有用である。こうした用途では特に被加熱物を調理庫内に出し入れする時間を短縮する必要があるが、載置台上に置かれる調理容器はそれ自体がかなりの高温になるため、そうした容器を出し入れするには手間が掛かり、時間のロスにもなるという問題がある。また、誘導加熱の場合には、誘導加熱コイルの直上から外れた位置に調理容器が置かれると加熱効率が落ちるため、特に使用者が注意しなくても調理容器が調理庫内の最適な加熱位置に置かれるようにすることが望まれている。   In addition, the above-described combined heating cooking apparatus uses a combination of microwave heating and induction heating, for example, cooking such as hamburger, dumplings, etc., that heats the food inside while attaching moderate burnt eyes to the food. This is especially useful when cooking is required in a short time for business use. In such an application, it is necessary to shorten the time for putting the heated object in and out of the cooking chamber. However, the cooking container placed on the mounting table itself becomes very hot, so it is troublesome to take in and out such a container. There is a problem that it takes time and is a loss of time. In addition, in the case of induction heating, if the cooking container is placed at a position off the top of the induction heating coil, the heating efficiency is lowered, so that the cooking container is optimally heated in the cooking chamber without any particular attention from the user. It is desired to be placed in position.

またこうした複合型加熱調理装置では、油を使用した焼き調理が多くなるため、調理庫内で油煙が発生し易く、調理庫内の空気を機外に排出する排気ダクト内も油煙による油汚れが付着し易い。油汚れが酷くなると衛生上好ましくないばかりでなく、発火事故等が起こり易くなって安全上も問題がある。しかしながら、一般的には排気ダクト内は掃除がしにくく、掃除をするには手間と時間が掛かるという問題がある。   In addition, in such a combined cooking device, oil cooking is often used, so oily smoke is likely to be generated in the cooking chamber, and the oil in the exhaust duct that exhausts the air in the cooking chamber to the outside of the machine is also contaminated with oily smoke. Easy to adhere. If the oil stain becomes severe, not only is it not preferable for hygiene, but there is a problem in terms of safety because ignition accidents are likely to occur. However, in general, the exhaust duct is difficult to clean, and there is a problem that it takes time and effort to clean.

この第１発明及び以下の各発明に係る加熱調理装置において、磁束通過用部材としては例えばステンレス等の金属板に多数の小孔を穿設したパンチング板を利用することができる。   In the cooking device according to the first invention and each of the following inventions, a punching plate in which a large number of small holes are formed in a metal plate such as stainless steel can be used as the magnetic flux passage member.

上記第１発明に係る加熱調理装置では、載置板と磁束通過用部材との間に間隙を形成するべく配設された１乃至複数の絶縁部材により、その周面が囲まれる扁平状の通風路が形成される。この通風路の下面には磁束通過用部材の上面が露出しており、通風路を通る相対的に低温の空気と磁束通過用部材とが熱交換を行うことで磁束通過用部材は冷却される。また、載置板上に誘導加熱される調理容器が載置されていると、この調理容器の熱が載置板に伝導して載置板も高温になるが、通風路を通る空気が一種の遮熱層として機能し、載置板の熱が磁束通過用部材に伝わることを抑制することができる。これにより、磁束通過用部材の温度上昇を抑えることができる。   In the cooking device according to the first aspect of the present invention, the flat ventilation in which the peripheral surface is surrounded by one or more insulating members arranged to form a gap between the mounting plate and the magnetic flux passage member. A path is formed. The upper surface of the magnetic flux passage member is exposed on the lower surface of the ventilation path, and the magnetic flux passage member is cooled by heat exchange between the relatively low temperature air passing through the ventilation path and the magnetic flux passage member. . In addition, when a cooking vessel that is induction-heated is placed on the placement plate, the heat of the cooking vessel is conducted to the placement plate and the placement plate also becomes hot, but the air passing through the ventilation path is a kind. It can control that the heat of a mounting board is transmitted to the member for magnetic flux passage. Thereby, the temperature rise of the member for magnetic flux passage can be suppressed.

またこの第１発明に係る加熱調理装置ではさらに、前記磁束通過用部材と前記誘導加熱コイルとの間に設けられた１乃至複数の絶縁部材により、該磁束通過用部材及び誘導加熱コイルを冷却するための別の通風路を形成している。 In the cooking device according to the first aspect of the present invention, the magnetic flux passage member and the induction heating coil are further cooled by one or more insulating members provided between the magnetic flux passage member and the induction heating coil. It forms another air passage for.

この構成によれば、磁束通過用部材と誘導加熱コイルとの間に形成された別の通風路を通る相対的に低温の空気と誘導加熱コイルとが熱交換を行うことで磁束通過用部材のみならず、誘導加熱コイルが冷却される。また、この別の通風路を通る空気が一種の遮熱層として機能し、誘導加熱コイルの熱が磁束通過用部材に伝わることも抑制することができる。これにより、さらに一層、磁束通過用部材の温度上昇を抑えることができる。さらにまた、上記の別の通風路は、磁束通過用部材の熱が誘導加熱コイルに伝わることも抑制できる。   According to this configuration, the relatively low temperature air passing through another ventilation path formed between the magnetic flux passage member and the induction heating coil exchanges heat with the induction heating coil so that only the magnetic flux passage member is obtained. Instead, the induction heating coil is cooled. Further, the air passing through the other ventilation path functions as a kind of heat shield layer, and it is possible to suppress the heat of the induction heating coil from being transmitted to the magnetic flux passage member. Thereby, the temperature rise of the magnetic flux passage member can be further suppressed. Furthermore, said another ventilation path can also suppress that the heat | fever of the magnetic flux passage member is transmitted to the induction heating coil.

またこの第１発明に係る加熱調理装置ではさらに、前記磁束通過用部材の上部側に設けられる前記絶縁部材の少なくとも１つは、該磁束通過用部材の反りを抑制する押止部を一体に有している。 In the cooking device according to the first aspect of the present invention, at least one of the insulating members provided on the upper side of the magnetic flux passage member integrally has a pressing portion that suppresses warpage of the magnetic flux passage member. Is doing .

この構成によれば、前記磁束通過用部材の上部側に設けられる前記絶縁部材の少なくとも１つは、該磁束通過用部材の反りを抑制する押止部を一体に有する構成することにより、磁束通過用部材の温度が上昇して熱膨張した場合でも、押止部により上方側への反りが抑えられるので、載置板上に置かれた調理容器の底面と磁束通過用部材との距離が短くならず、その距離短縮による誘導加熱効率の低下を防止することができる。また、磁束通過用部材が載置板の下面に接触したりきわめて近接したりすることを防止できるので、磁束通過用部材の熱が載置板に伝導することも回避できる。それにより、載置板の異常な温度上昇による誘電損失の増加を防止でき、高周波加熱の効率の低下を回避することもできる。また、加熱に伴う磁束通過用部材の反りと冷却に伴うその反りからの戻りとを繰り返すことを防止することで、磁束通過用部材の長寿命化を図ることができる。 According to this configuration, at least one of the insulating members provided on the upper side of the magnetic flux passage member integrally includes a holding portion that suppresses warpage of the magnetic flux passage member, thereby allowing the magnetic flux passage. Even when the temperature of the member for heating rises and the thermal expansion occurs, the warping upward is suppressed by the holding part, so the distance between the bottom surface of the cooking container placed on the mounting plate and the member for passing magnetic flux is short. In addition, a decrease in induction heating efficiency due to the shortening of the distance can be prevented. Further, since the magnetic flux passing member can be prevented from coming into contact with or very close to the lower surface of the mounting plate, it is possible to avoid the heat of the magnetic flux passing member from being conducted to the mounting plate. Thereby, an increase in dielectric loss due to an abnormal temperature rise of the mounting plate can be prevented, and a decrease in the efficiency of high-frequency heating can also be avoided. Further, it is possible to prolong the life of the magnetic flux passage member by preventing the magnetic flux passage member from warping due to heating and returning from the warpage due to cooling .

上記第１の目的を達成するために成された第２発明は、箱形状の調理庫と、該調理庫内に収容された食品を高周波加熱するためのマイクロ波を発生するマグネトロンを含む高周波加熱手段と、前記調理庫内に収容された発熱体を誘導加熱するための交番磁束を発生する誘導加熱コイルを含む誘導加熱手段と、を具備する加熱調理装置において、
前記調理庫の底壁面の少なくとも一部は、その下方に配設された前記誘導加熱コイルから発生する磁束を通過させる一方、マイクロ波の通過を阻止する磁束通過用部材で形成され、
前記磁束通過用部材の上部には１乃至複数の上部側絶縁部材を挟んで前記発熱体を載置可能な絶縁体から成る載置板を配置し、
前記１乃至複数の上部側絶縁部材により、前記載置板の熱が前記磁束通過用部材に伝導するのを抑えるとともに該磁束通過用部材を冷却するための第１通風路を形成し、
前記磁束通過用部材と前記誘導加熱コイルとの間に設けられた複数の下部側絶縁部材により、該下部側絶縁部材の１つと前記磁束通過用部材との間に該磁束通過用部材を冷却するための第２通風路を、その下部側絶縁部材の１つと前記誘導加熱コイルとの間に該誘導加熱コイルを冷却するための第３通風路を形成したことを特徴としている。 A second invention made to achieve the first object is a high-frequency heating including a box-shaped cooking chamber and a magnetron that generates microwaves for high-frequency heating of food stored in the cooking chamber. A heating cooking apparatus comprising: means and induction heating means including an induction heating coil that generates an alternating magnetic flux for induction heating the heating element accommodated in the cooking chamber;
At least a part of the bottom wall surface of the cooking chamber is formed of a magnetic flux passage member that blocks the passage of microwaves while allowing the magnetic flux generated from the induction heating coil disposed below the passage to pass through.
On the upper part of the magnetic flux passage member, a placing plate made of an insulator on which the heating element can be placed with one or more upper insulating members sandwiched therebetween is disposed,
The one or more upper insulating members suppress the conduction of heat of the mounting plate to the magnetic flux passage member and form a first ventilation path for cooling the magnetic flux passage member,
The magnetic flux passage member is cooled between one of the lower insulation members and the magnetic flux passage member by a plurality of lower insulation members provided between the magnetic flux passage member and the induction heating coil. The second ventilation path is characterized in that a third ventilation path for cooling the induction heating coil is formed between one of the lower insulating members and the induction heating coil.

上記第２発明に係る加熱調理装置では、載置板と磁束通過用部材との間に形成された第１通風路の下面には磁束通過用部材の上面が露出しており、第１通風路を通る相対的に低温の空気と磁束通過用部材とが熱交換を行うことで磁束通過用部材は冷却される。また、載置板上に誘導加熱される調理容器が載置されていると、この調理容器の熱が載置板に伝導して載置板も高温になるが、第１通風路を通る空気が一種の遮熱層として機能し、載置板の熱が磁束通過用部材に伝わることを抑制することができる。また磁束通過用部材と誘導加熱コイルとの間に形成された第２通風路の上面には磁束通過用部材の下面が露出しており、第２通風路を通る相対的に低温の空気と磁束通過用部材とが熱交換を行うことで磁束通過用部材は冷却される。さらにまた、磁束通過用部材と誘導加熱コイルとの間に形成された第３通風路の下面には誘導加熱コイルの上面が露出しており、第３通風路を通る相対的に低温の空気と誘導加熱コイルとが熱交換を行うことで誘導加熱コイルは冷却される。また、第２及び第３通風路を通る空気が一種の遮熱層として機能し、誘導加熱コイルの熱が磁束通過用部材に伝わることも抑制することができる。これにより、磁束通過用部材の温度上昇を一層効果的に抑えることができる。さらにまた、第２及び第３通風路は磁束通過用部材の熱が誘導加熱コイルに伝わることも抑制できる。 In the cooking device according to the second aspect, the upper surface of the magnetic flux passage member is exposed on the lower surface of the first air passage formed between the mounting plate and the magnetic flux passage member, and the first air passage. The relatively low-temperature air passing through and the magnetic flux passage member exchange heat to cool the magnetic flux passage member. In addition, when a cooking vessel to be induction-heated is placed on the placement plate, the heat of the cooking vessel is conducted to the placement plate and the placement plate also becomes hot, but the air passing through the first ventilation path Functions as a kind of heat shield layer, and it is possible to suppress the heat of the mounting plate from being transmitted to the magnetic flux passing member. Further, the lower surface of the magnetic flux passage member is exposed on the upper surface of the second air passage formed between the magnetic flux passage member and the induction heating coil, and relatively low-temperature air and magnetic flux passing through the second air passage. The magnetic flux passing member is cooled by exchanging heat with the passing member. Furthermore, the upper surface of the induction heating coil is exposed on the lower surface of the third ventilation path formed between the magnetic flux passage member and the induction heating coil, and relatively low-temperature air passing through the third ventilation path and The induction heating coil is cooled by exchanging heat with the induction heating coil. Further, the air passing through the second and third ventilation paths functions as a kind of heat shield layer, and the heat of the induction heating coil can be prevented from being transmitted to the magnetic flux passage member. Thereby, the temperature rise of the member for magnetic flux passage can be suppressed more effectively. Furthermore, the second and third ventilation paths can also suppress the heat of the magnetic flux passage member from being transmitted to the induction heating coil.

またその一態様として、前記押止部は細長形状であって、その一端が支持され、他端は前記通風路に向いて開放されて成るものとすることができる。   Further, as one aspect thereof, the pressing portion may be an elongated shape, one end of which is supported, and the other end is opened toward the ventilation path.

この構成によれば、押止部を設けた場合でも通風路内に向いた開放端側では空気流が確保されるので、磁束通過用部材を十分に冷却することができる。   According to this configuration, even when the pressing portion is provided, an air flow is ensured on the open end side facing the ventilation path, so that the magnetic flux passage member can be sufficiently cooled.

また前記押止部は円環体の内方に放射状に複数設けられている構成とするとよい。   Moreover, it is good for the said holding | suppressing part to be set as the structure provided in multiple numbers radially inside the torus.

この構成によれば、磁束通過用部材をその周囲からほぼ均等に押さえることで、磁束通過用部材の反りを顕著に防止することができる。   According to this configuration, it is possible to remarkably prevent warping of the magnetic flux passage member by pressing the magnetic flux passage member almost uniformly from the periphery thereof.

また上記第１又は第２発明に係る加熱調理装置では、前記調理庫の底壁面は矩形状であって、前面側の一方のコーナーの下方に前記通風路へ空気を送るための吸気口が設けられ、そのコーナーと対角線上に位置する後面側のコーナーの下方に前記通風路を通った空気を吐き出す排気口を設けた構成とすることができる。 In the cooking device according to the first or second invention, the bottom wall surface of the cooking chamber is rectangular, and an intake port for sending air to the ventilation path is provided below one corner on the front side. In addition, an exhaust port that discharges the air that has passed through the ventilation path can be provided below the corner on the rear side that is located diagonally to the corner.

誘導加熱コイルや磁束通過用部材などは外形が円形状であるのに対し調理庫の底壁面は矩形状であるため、そのコーナーはデッドスペースとなり易いが、コーナーに吸気口、排気口を設け、さらにはそこに送風用のファンやファンモータなどの送風機構を装着することでスペースの有効利用を図ることができる。これにより、そうした送風機構等を配設するために調理庫のサイズを無駄に大きくする必要がなく、装置全体の外形サイズを小さくすることができる。   The induction heating coil, magnetic flux passing member, etc. have a circular outer shape, but the bottom wall surface of the cooking cabinet is rectangular, so its corner tends to become a dead space, but the corner is provided with an inlet and an outlet, Furthermore, the space can be effectively used by installing a blower mechanism such as a fan for blowing air or a fan motor. Thereby, it is not necessary to unnecessarily increase the size of the cooking chamber in order to arrange such a blower mechanism and the like, and the overall size of the apparatus can be reduced.

また誘導加熱コイルと磁束通過用部材との間に通風路を設けた場合に、前記通風路において前記誘導加熱コイルと熱交換を行った後の空気の温度を検出する温度検出手段を備える構成とするとよい。   In addition, when a ventilation path is provided between the induction heating coil and the magnetic flux passage member, a structure including temperature detection means for detecting a temperature of air after heat exchange with the induction heating coil in the ventilation path; Good.

例えば異常発生によって誘導加熱コイルの温度が異常に上昇すると通風路を通過した後の空気の温度も高くなる。したがって、温度検出手段による検出温度に基づいて誘導加熱コイルやその駆動回路などの異常状態を確実に認識することができる。   For example, if the temperature of the induction heating coil rises abnormally due to the occurrence of an abnormality, the temperature of the air after passing through the ventilation path also increases. Therefore, abnormal states of the induction heating coil and its drive circuit can be reliably recognized based on the temperature detected by the temperature detecting means.

また第１又は第２発明に係る加熱調理装置において、前記載置板は、通常加熱時における前記発熱体の温度以下の温度範囲で誘電損失の増加が生じない特性を有する材料を主成分とするものであることが好ましい。 In the cooking device according to the first or second invention, the mounting plate is mainly composed of a material having a characteristic that does not increase dielectric loss in a temperature range below the temperature of the heating element during normal heating. It is preferable.

この構成によれば、通常使用時には載置板によるマイクロ波の吸収は小さいので、高い高周波加熱効率を達成することができる。なお、一般的には誘導加熱と高周波加熱とを併用した場合における通常加熱時の発熱体の最高温度は２００〜２５０℃程度であり、これ以下の低い温度範囲で誘電損失の増加が生じない特性を有する材料としては例えばコージライト（２ＭｇＯ・２Ａｌ2Ｏ3・５ＳｉＯ2）などが挙げられる。 According to this configuration, since microwave absorption by the mounting plate is small during normal use, high high-frequency heating efficiency can be achieved. In general, the maximum temperature of the heating element during normal heating when induction heating and high frequency heating are used in combination is about 200 to 250 ° C., and the dielectric loss does not increase in a lower temperature range below this. Examples of the material having the above include cordierite (2MgO · 2Al 2 O 3 · 5SiO 2 ).

また一態様として、前記発熱体としての調理容器を前後方向に移動可能に保持し、該調理容器を後方に移動させた状態で該調理容器の底面が前記載置板上に接し且つその位置が前記誘導加熱コイルの上方となるように移動を行う容器保持手段と、
を備えることを特徴としている。 Moreover, as one aspect, the cooking container as the heating element is held so as to be movable in the front-rear direction, and the bottom surface of the cooking container is in contact with the mounting plate in a state where the cooking container is moved backward, and the position thereof is Container holding means for moving so as to be above the induction heating coil;
It is characterized by having.

この構成によれば、容器保持手段により調理容器を後方へと移動させると、調理容器が誘導加熱のために適切な位置、つまりは効率良く加熱が行われる位置にセットされる。また、このとき調理容器の底面が載置板上に接するので、誘導加熱コイルと調理容器底面との離間距離も常に一定となる。これにより、使用者に煩わしい手間を負わせることなく、常に最適又はそれに近い状態の誘導加熱調理を行うことが可能になる。また、調理前又は調理後に容器保持手段により調理容器を前方へと移動させると、該調理容器内に食品を簡単に出し入れすることができる。特に調理後には調理容器自体が熱くなっていて食品を取り出しにくく火傷等もし易いが、調理容器が前方に移動することでこうした火傷等のおそれも軽減することができる。 According to this configuration , when the cooking container is moved backward by the container holding means, the cooking container is set to an appropriate position for induction heating, that is, a position where heating is performed efficiently. At this time, since the bottom surface of the cooking container is in contact with the mounting plate, the distance between the induction heating coil and the bottom surface of the cooking container is always constant. Thereby, it becomes possible to perform induction heating cooking always optimal or close to it, without burdening a user with troublesome trouble. Further, when the cooking container is moved forward by the container holding means before or after cooking, the food can be easily put in and out of the cooking container. In particular, after cooking, the cooking container itself is hot, and it is difficult to take out the food and it is easy to cause burns. However, the risk of such burns can be reduced by moving the cooking container forward.

また一実施態様として、前記容器保持手段は、前記調理容器を支持する支持手段と、該支持手段を前後で且つ前上がり傾斜でスライド移動させるべく案内する案内手段と、を含む構成とすることができる。 Moreover, as one embodiment, the container holding means includes a support means for supporting the cooking container, and a guide means for guiding the support means to slide forward and backward and tilt upward. it can.

この構成によれば、調理容器が前方に移動する際に上方にも移動するので、調理容器からの食品の取り出しを一層容易にすることができる。   According to this configuration, when the cooking container moves forward, the food container also moves upward, so that it is possible to further easily take out the food from the cooking container.

この場合でも、前記容器保持手段は、前記調理容器の底面の水平性を維持した状態で該調理容器を前後方向にスライド移動させる構成とするとよい。   Even in this case, the container holding means may be configured to slide the cooking container in the front-rear direction while maintaining the levelness of the bottom surface of the cooking container.

この構成によれば、調理容器内に収容されている食品が汁物など比較的液体が多いものであっても、こうした液体が調理容器の移動に伴ってこぼれることを防止することができる。   According to this configuration, even if the food contained in the cooking container has a relatively large amount of liquid such as soup, the liquid can be prevented from spilling as the cooking container moves.

また、前記容器保持手段は絶縁性を有し、前記調理容器は該容器保持手段に対し着脱可能である構成とするとよい。 The container holding means may have an insulating property, and the cooking container may be detachable from the container holding means.

この構成によれば、例えば調理容器を洗浄する際に該調理容器を容器保持手段から取り外すことができる。   According to this configuration, for example, when the cooking container is washed, the cooking container can be detached from the container holding means.

また、前記調理庫内の空気を外部に排出するための排気ダクトと、前記排気ダクトに内装され、前記筐体の外側から着脱可能である内筒部とを備えている。 Also, an exhaust duct for discharging the air in the cooking chamber to the outside, are furnished to the exhaust duct, are Bei Ete a cylindrical portion in detachable from the outside of the housing.

この構成によれば、調理時に調理庫内で発生した油煙などの排気は排気ダクトに装着された内筒部中を通って機外に排出されるため、油や煤などの汚れは内筒部の内面に付着する。そこで、この内筒部を筐体の外側から取り外し、これのみを掃除すればよい。また、内筒部の汚れが酷くなり過ぎて掃除で落ちにくくなった場合には、内筒部を新品に交換することもできる。したがって、装置本体の掃除に掛かる手間を軽減することができ、装置の稼働効率を上げることができる。 According to this configuration, exhaust gas such as oily smoke generated in the cooking chamber during cooking is discharged outside the machine through the inner cylinder part mounted on the exhaust duct. Adhere to the inner surface. Therefore, it is only necessary to remove this inner cylinder from the outside of the housing and clean only this. Moreover, when the dirt of the inner cylinder part becomes so severe that it becomes difficult to remove by cleaning, the inner cylinder part can be replaced with a new one. Therefore, it is possible to reduce the time and effort required for cleaning the apparatus main body, and to increase the operating efficiency of the apparatus.

また、前記内筒部を前記排気ダクトに内装したときに、該内筒部の内側に突出する排気温度検出用の温度検出手段を備える構成とするとよい。 Moreover , it is good to set it as the structure provided with the temperature detection means for exhaust temperature detection which protrudes inside this inner cylinder part, when the said inner cylinder part is built in the said exhaust duct.

この構成によれば、温度検出手段により調理庫からの排気の温度をモニタすることができるので、例えば調理庫内で食品の焦げ付きなどの異常状態を速やかに検知し、例えば使用者に報知することが可能となる。   According to this configuration, since the temperature of the exhaust gas from the cooking chamber can be monitored by the temperature detection means, for example, an abnormal state such as burning of food is quickly detected in the cooking chamber, for example, to notify the user. Is possible.

本発明の加熱調理装置によれば、誘導加熱の実行時にもパンチング板などの磁束通過用部材の温度上昇を抑制することができ、これによって例えば磁束通過用部材の反りなどの発生を起こりにくくすることができる。 According to the heating cooking apparatus of the present invention, it is possible to suppress the temperature rise of the magnetic flux passage member such as the punching plate even when performing the induction heating, thereby making it difficult to cause, for example, warping of the magnetic flux passage member. be able to.

以下、本発明の一実施例である複合型の加熱調理装置について図面を参照して説明する。 DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a combined cooking device according to an embodiment of the present invention will be described with reference to the drawings.

図１は本実施例の加熱調理装置１を右斜め上から見た外観斜視図、図２は本実施例の加熱調理装置１を左斜め上から見た外観斜視図、図３はドア３を開放した状態での左斜め上から見た外観斜視図である。また図４は本実施例の加熱調理装置１の概略側面縦断面図である。   FIG. 1 is an external perspective view of the cooking device 1 of the present embodiment as viewed from the upper right, FIG. 2 is an external perspective view of the cooking device 1 of the present embodiment as viewed from the upper left, and FIG. It is the external appearance perspective view seen from the diagonally upper left in the open state. FIG. 4 is a schematic side longitudinal sectional view of the cooking device 1 according to the present embodiment.

この加熱調理装置１は略直方体形状の筐体２を有し、筐体２の内部には前面が開放された略直方体形状の調理庫４が形成されている。調理庫４の前面開口は横開式のドア３により開閉される。このドア３の中央にはマイクロ波漏洩防止用のパンチング板と調理庫４内部を透視可能な耐熱ガラスとが設置され、またドア３の周囲には、ドア３の閉鎖時に調理庫４の前面開口周囲枠部４ａと接触して調理庫４内のマイクロ波が外部に漏洩するのを防止するマイクロ波漏洩防止構造３ａが設けられている。   The heating cooking apparatus 1 has a substantially rectangular parallelepiped casing 2, and a substantially rectangular parallelepiped cooking chamber 4 having a front surface opened is formed inside the casing 2. The front opening of the cooking chamber 4 is opened and closed by a side-opening door 3. A punching plate for preventing microwave leakage and a heat-resistant glass capable of seeing through the inside of the cooking cabinet 4 are installed at the center of the door 3, and the front opening of the cooking cabinet 4 is opened around the door 3 when the door 3 is closed. A microwave leakage prevention structure 3a that prevents the microwave in the cooking cabinet 4 from leaking to the outside in contact with the surrounding frame portion 4a is provided.

筐体２の前面上部でドア３の閉鎖時に隠れない位置に、複数の操作キーが配置されたキー入力部とセグメントＬＣＤなどによる表示部とを有する操作パネル５が配設されており、調理者はキー入力部で各種の加熱調理条件や運転開始・停止などを指示し、表示部にはそうした加熱調理条件や運転残り時間などが表示されるようになっている。また、筐体２の前面下部でドア３の下側には、後述する筐体２内の誘導加熱部を主として冷却するための外気を取り込むための外気取入口６が横に広く形成されている。   An operation panel 5 having a key input unit on which a plurality of operation keys are arranged and a display unit using a segment LCD or the like is disposed at a position that is not hidden when the door 3 is closed on the front surface of the housing 2. The key input unit instructs various cooking conditions and start / stop of operation, and the display unit displays such cooking conditions and remaining operation time. An outside air intake 6 for taking in outside air mainly for cooling an induction heating unit in the housing 2 to be described later is formed wide on the lower side of the front surface of the housing 2 and below the door 3. .

図４に示すように、調理庫４はドア３を閉鎖した際にその裏面に相当する前面を除く五面、即ち、後面部４ｂ、天面部４ｃ、底面部４ｄ、左側面部４ｅ（図４では現れない）及び右側面部４ｆを有する略直方体箱形状であり、前述のように前面開口がドア３により閉鎖されるとほぼ密閉状態となる。調理庫４内には調理対象である食品が収容される調理容器９０が収納されるが、ここでは調理容器９０は後述するような機構により前後に移動可能となっている。この調理容器９０に収容された食品を加熱調理するために、電子レンジ調理のための高周波（マイクロ波）加熱手段と、調理容器９０を加熱して間接的に食品を調理するための誘導加熱手段とが併設されている。   As shown in FIG. 4, when the cooking chamber 4 closes the door 3, the five surfaces except the front surface corresponding to the back surface thereof, that is, the rear surface portion 4b, the top surface portion 4c, the bottom surface portion 4d, and the left side surface portion 4e (in FIG. 4). And a substantially rectangular parallelepiped box shape having a right side surface portion 4f, and when the front opening is closed by the door 3 as described above, it is almost sealed. A cooking container 90 for storing food to be cooked is housed in the cooking cabinet 4, but here the cooking container 90 can be moved back and forth by a mechanism as will be described later. In order to heat-cook the food contained in the cooking container 90, high-frequency (microwave) heating means for cooking in a microwave oven, and induction heating means for cooking the food indirectly by heating the cooking container 90 And is attached.

高周波加熱手段として、調理庫４の後面部４ｂの後方上部にはマイクロ波を発生するマグネトロン１０が設置され、マグネトロン１０で発生したマイクロ波は筐体２内上部を前方に延伸する導波管１１内を通って伝播し、調理庫４の天面部４ｃに設けられたマイクロ波拡散室１２にまで案内される。マイクロ波拡散室１２内にはアンテナ駆動モータ１４により略水平面内で回転駆動される放射アンテナ１３が設けられ、これによりマイクロ波は調理庫４の天面部４ｃの略中央の給電口から調理庫４内に拡散されながら放射される。このマイクロ波の作用によって調理容器９０（図４では図示しない）内の食品は加熱調理される。   As a high-frequency heating means, a magnetron 10 that generates microwaves is installed at the rear upper part of the rear surface portion 4b of the cooking cabinet 4, and the microwaves generated by the magnetron 10 extend forward in the upper part of the housing 2. It propagates through the interior and is guided to the microwave diffusion chamber 12 provided in the top surface portion 4 c of the cooking chamber 4. Inside the microwave diffusion chamber 12 is provided a radiation antenna 13 that is rotationally driven in a substantially horizontal plane by an antenna drive motor 14, whereby microwaves are fed from a substantially central feeding port of the top surface portion 4 c of the cooking chamber 4. Radiated while diffusing inside. The food in the cooking container 90 (not shown in FIG. 4) is heated and cooked by the action of the microwave.

一方、誘導加熱手段として、調理庫４の底面部４ｄの下方には調理容器９０自体を誘導加熱するための誘導加熱コイル５３が略水平に設置されており、後述するインバータ回路から誘導加熱コイル５３に高周波電流が供給されると交番磁束が発生し、その磁束は底面部４ｄを通過して調理庫４内に侵入し、例えば磁性金属で形成された調理容器９０の底部を横切る。すると、その交番磁束の誘導作用によって調理容器９０の底部に渦電流が誘起され、ジュール熱により該調理容器９０は高温になり、その調理容器９０内に収容されている食品は加熱調理される。   On the other hand, as an induction heating means, an induction heating coil 53 for induction heating of the cooking container 90 itself is installed substantially horizontally below the bottom surface portion 4d of the cooking cabinet 4, and an induction heating coil 53 from an inverter circuit described later is installed. When a high-frequency current is supplied, an alternating magnetic flux is generated. The magnetic flux passes through the bottom surface portion 4d and enters the cooking cabinet 4, and crosses the bottom of the cooking vessel 90 formed of, for example, magnetic metal. Then, an eddy current is induced at the bottom of the cooking container 90 due to the induction action of the alternating magnetic flux, the cooking container 90 becomes high temperature due to Joule heat, and the food contained in the cooking container 90 is cooked.

この誘導加熱コイル５３を含む誘導加熱ユニット５０と調理庫４の底面部４ｄの構造について、図４に加えて図５〜図７により詳細に説明する。図５は調理庫４の底面構造とその下方に位置する誘導加熱ユニット５０の組立構造図、図６は誘導加熱ユニット５０の組立構造図、図７は筐体を取り除いた状態で右斜め下方から見た斜視図である。   The structure of the induction heating unit 50 including the induction heating coil 53 and the bottom surface portion 4d of the cooking cabinet 4 will be described in detail with reference to FIGS. 5 is an assembly structure diagram of the induction heating unit 50 located below the bottom structure of the cooking cabinet 4, FIG. 6 is an assembly structure diagram of the induction heating unit 50, and FIG. 7 is an oblique view from the lower right with the housing removed. FIG.

調理庫４の底面部４ｄは、円形状の大きな開口が形成されたステンレス（例えばＳＵＳ３０４）製の底板４０と、同材料の円環状の底板金具４１と、所定径の小孔が多数穿孔された同材料で円形状のパンチング板（本発明における磁束通過用部材に相当）４２とから成る。底板金具４１とパンチング板４２とはスポット溶接等の強固な固着方法によって一体化され、それらは底板金具４１の外周縁のネジ孔に挿通されたネジ４６及びナット４７により底板４０に固定されている。例えば、底板４０及び底板金具４１の板厚は０．５ｍｍであってその剛性は高いが、パンチング板４２は磁束の通過効率を高めるために０．１ｍｍと薄い板厚とされている。   The bottom surface portion 4d of the cooking chamber 4 has a stainless steel (for example, SUS304) bottom plate 40 formed with a large circular opening, an annular bottom plate metal fitting 41 of the same material, and a large number of small holes with a predetermined diameter. And a circular punching plate (corresponding to a member for passing magnetic flux in the present invention) 42 made of the same material. The bottom plate fitting 41 and the punching plate 42 are integrated by a strong fixing method such as spot welding, and they are fixed to the bottom plate 40 by screws 46 and nuts 47 inserted through screw holes on the outer peripheral edge of the bottom plate fitting 41. . For example, the plate thickness of the bottom plate 40 and the bottom plate metal fitting 41 is 0.5 mm and its rigidity is high, but the punching plate 42 is made as thin as 0.1 mm in order to increase the passage efficiency of magnetic flux.

調理庫４の底面部４ｄの上には、例えばマイカ板である上部第１絶縁部材４３と上部第２絶縁部材４４とが装着され、その上に食品を収容した調理容器を置くための載置板４５が載せられる。載置板４５の周縁と調理庫４の立壁面との隙間には、例えばシリコーンゴムなどから成るシール部材４８が設けられており、調理庫４内でこぼれた液体が載置板４５の下方に落ちにくくなっている。   An upper first insulating member 43 and an upper second insulating member 44, which are, for example, mica plates, are mounted on the bottom surface portion 4d of the cooking cabinet 4, and a placement for placing a cooking container containing food on it is mounted. A plate 45 is placed. A seal member 48 made of, for example, silicone rubber is provided in a gap between the peripheral edge of the mounting plate 45 and the standing wall surface of the cooking cabinet 4, and liquid spilled in the cooking cabinet 4 is placed below the mounting plate 45. It is hard to fall.

載置板４５は、誘導加熱のために磁束を通過させるものである必要がある一方、マイクロ波により高周波加熱されにくいように低損失の誘電体材料である必要がある。また、高温になる調理容器に直接接触するため耐熱性も必要である。そこで例えば載置板４５はコージライト（２ＭｇＯ・２Ａｌ2Ｏ3・５ＳｉＯ2）を主成分とするものとすることができる。誘導加熱と高周波加熱とが同時に行われた場合に調理容器の温度は最高で２００〜２５０℃程度になるが、コージライトはそうした温度以下の温度範囲では誘電損失が小さい。そのため、通常の使用時には載置板４５でのマイクロ波の吸収を少なくし、高周波加熱の効率を高めることができる。 The mounting plate 45 needs to pass a magnetic flux for induction heating, but needs to be a low-loss dielectric material so that it is difficult to be heated by microwaves at high frequencies. In addition, heat resistance is also necessary because it is in direct contact with a cooking container that becomes hot. Therefore, for example, the mounting plate 45 can be made mainly of cordierite (2MgO · 2Al 2 O 3 · 5SiO 2 ). When induction heating and high-frequency heating are performed simultaneously, the temperature of the cooking vessel is about 200 to 250 ° C. at the maximum, but cordierite has a small dielectric loss in a temperature range below that temperature. Therefore, during normal use, the microwave absorption by the mounting plate 45 can be reduced, and the efficiency of high-frequency heating can be increased.

図８は載置板４５の詳細図であり、（ａ）は上面平面図、（ｂ）は正面平面図、（ｃ）は（ｂ）中のＡ部の拡大断面図である。載置板４５はその周縁部４５ａが全周に亘って外周に向かって上向きに傾斜した形状となっている。これにより、載置板４５上に食品の汁や油などの液体がこぼれたときに、載置板４５の周縁端から下方に流れ落ちることを防止することができる。   8A and 8B are detailed views of the mounting plate 45, where FIG. 8A is a top plan view, FIG. 8B is a front plan view, and FIG. 8C is an enlarged cross-sectional view of a portion A in FIG. The mounting plate 45 has a shape in which a peripheral edge 45a is inclined upward toward the outer periphery over the entire periphery. Thereby, when liquids, such as a juice of food and oil, spilled on the mounting board 45, it can prevent flowing down from the peripheral edge of the mounting board 45. FIG.

底板４０の上に密着する上部第１絶縁部材４３は、円環部４３ａの内周縁に放射状に複数の短冊形状の延出片４３ｂを一体に有しており、この延出片４３ｂがパンチング板４２の上方への反りを防止する本発明における押止部として機能する。   The upper first insulating member 43 that is in close contact with the bottom plate 40 integrally has a plurality of strip-shaped extending pieces 43b integrally formed on the inner peripheral edge of the annular portion 43a. The extending pieces 43b are punched plates. It functions as a retaining portion in the present invention that prevents warping of 42 upward.

一方、上部第２絶縁部材４４は内側に大きな開口４４ａを有する形状となっている。上部第１絶縁部材４３及び上部第２絶縁部材４４はいずれも外周側が全周に亘って繋がっており、内周側に開口が形成されているため、パンチング板４２を下面、載置板４５を上面とし、上部第１絶縁部材４３、上部第２絶縁部材４４を側面（周面）とする扁平な空隙が形成され、これがパンチング板４２の上方の通風路（又は第１通風路）Ｔ１となる。底面部４ｄと上部第１絶縁部材４３との接触面、上部第１絶縁部材４３と上部第２絶縁部材４４との接触面、及び上部第２絶縁部材４４と載置板４５との接触面はそれぞれ緊密に密着しているため、通風路Ｔ１は側面からの空気流の漏れが殆どない構造となっている。   On the other hand, the upper second insulating member 44 has a shape having a large opening 44a inside. Each of the upper first insulating member 43 and the upper second insulating member 44 has an outer peripheral side that is connected over the entire circumference, and an opening is formed on the inner peripheral side, so that the punching plate 42 is the lower surface and the mounting plate 45 is A flat air gap is formed with the upper first insulating member 43 and the upper second insulating member 44 as side surfaces (circumferential surfaces) on the upper surface, and this becomes the ventilation path (or first ventilation path) T1 above the punching plate 42. . The contact surface between the bottom surface portion 4d and the upper first insulating member 43, the contact surface between the upper first insulating member 43 and the upper second insulating member 44, and the contact surface between the upper second insulating member 44 and the mounting plate 45 are as follows. Since they are in close contact with each other, the air passage T1 has a structure in which almost no airflow leaks from the side surface.

パンチング板４２の下方に設置される誘導加熱ユニット５０にあっては、図６に示すように、上面が開放されたケース５１の内側に、平板渦巻き状に巻回されて成る扁平略円盤形状の誘導加熱コイル５３が収容されている。このケース５１の前面側右端のコーナーには上記通風路Ｔ１及び後述する他の通風路Ｔ２、Ｔ３への空気流入口となる吸気口５１ａが形成され、その下方に、冷却用ファンモータやこれにより回転駆動されるファンを含む誘導加熱ユニット冷却ファンユニット５２が装着されている。一方、誘導加熱コイル５３の中心部を挟んで吸気口５１ａと対向する位置には通風路Ｔ１、Ｔ２、Ｔ３からの空気流出口となる排気口５１ｂが形成されている。なお、この排気口５１ｂには、排出される空気の温度を検出する温度センサ５７が設けられている。   In the induction heating unit 50 installed below the punching plate 42, as shown in FIG. 6, a flat, substantially disk-like shape formed by winding a flat plate inside a case 51 whose upper surface is open. An induction heating coil 53 is accommodated. An air inlet 51a serving as an air inlet to the ventilation path T1 and other ventilation paths T2 and T3 to be described later is formed in the corner at the right end of the front side of the case 51. An induction heating unit cooling fan unit 52 including a fan that is driven to rotate is mounted. On the other hand, an exhaust port 51b serving as an air outlet from the ventilation paths T1, T2, and T3 is formed at a position facing the intake port 51a across the center of the induction heating coil 53. The exhaust port 51b is provided with a temperature sensor 57 that detects the temperature of the discharged air.

誘導加熱コイル５３の上方、つまり誘導加熱コイル５３とパンチング板４２との間には、例えばマイカ板であってそれぞれ異なる形状の下部第１絶縁部材５４、下部第２絶縁部材５５、及び下部第３絶縁部材５６が装着されている。最上部の下部第３絶縁部材５６は略円環状である。真中の下部第２絶縁部材５５は略円板形状であって後方側に開口５５ａが形成され、前方側に外縁から内方に窪んだ凹部５５ｂを有する形状である。そして、最下部の下部第１絶縁部材５４は略円板形状であって中央に円形状の開口５４ａが形成され、その前方側には開口５４ａから扇状に外周縁まで繋がる切欠部５４ｂが設けられ、後方側には開口５４ａから扇状に窪んだ凹部５４ｃとなっている。   Above the induction heating coil 53, that is, between the induction heating coil 53 and the punching plate 42, for example, a lower first insulating member 54, a lower second insulating member 55, and a lower third plate which are mica plates and have different shapes. An insulating member 56 is attached. The uppermost lower third insulating member 56 is substantially annular. The lower second insulating member 55 in the middle has a substantially disk shape and has an opening 55a on the rear side and a recess 55b recessed inward from the outer edge on the front side. The lowermost lower first insulating member 54 has a substantially disc shape, and a circular opening 54a is formed at the center. A cutout portion 54b connected from the opening 54a to the outer peripheral edge is provided on the front side thereof. On the rear side, there is a concave portion 54c recessed in a fan shape from the opening 54a.

こうした特徴的な形状の下部第１、第２、及び第３絶縁部材５４、５５、５６が積層されることにより、誘導加熱コイル５３とパンチング板４２との間には、下部第２絶縁部材５５を仕切りとして、上側に第２通風路Ｔ２、下側に第３通風路Ｔ３が形成される。即ち、第２通風路Ｔ２は、パンチング板４２を上面、下部第２絶縁部材５５を下面とし、下部第３絶縁部材５６を側面（周面）とする扁平な空隙に形成された通風路であって、下部第２絶縁部材５５の凹部５５ｂが空気入口であり、開口５５ａが空気出口である。また第３通風路Ｔ３は、下部第２絶縁部材５５を上面、誘導加熱コイル５３の上面を下面とし、下部第１絶縁部材５４を側面（周面）とする扁平な空隙に形成された通風路であって、切欠部５４ｂが空気入口であり、凹部５４ｃが空気出口である。   By stacking the lower first, second, and third insulating members 54, 55, 56 having such characteristic shapes, the lower second insulating member 55 is interposed between the induction heating coil 53 and the punching plate 42. As a partition, a second ventilation path T2 is formed on the upper side, and a third ventilation path T3 is formed on the lower side. That is, the second ventilation path T2 is a ventilation path formed in a flat gap with the punching plate 42 as an upper surface, the lower second insulating member 55 as a lower surface, and the lower third insulating member 56 as a side surface (circumferential surface). The recess 55b of the lower second insulating member 55 is an air inlet, and the opening 55a is an air outlet. The third ventilation path T3 is a ventilation path formed in a flat air gap having the lower second insulating member 55 as an upper surface, the upper surface of the induction heating coil 53 as a lower surface, and the lower first insulating member 54 as a side surface (circumferential surface). In addition, the notch 54b is an air inlet and the recess 54c is an air outlet.

第１、第２、第３通風路Ｔ１、Ｔ２、Ｔ３はいずれも吸気口５１ａを空気流入口とし、排気口５１ｂを空気流出口とする通風路であり、誘導加熱ユニット冷却ファンユニット５２により外気取入口６を通して吸引された相対的に低温の外気が３つの通風路Ｔ１、Ｔ２、Ｔ３に分岐されて並行して流れ、排気口５１ｂで合流し排気路２０を経て筐体２の後面下部に形成された排気口８から機外に排出される。第１通風路Ｔ１は、主として、パンチング板４２を上方から冷却するとともに、調理容器９０からの熱の伝導によって高温になる載置板４５からの熱がパンチング板４２に伝わるのを遮断するためのものである。第２通風路Ｔ２は、主としてパンチング板４２を下方から冷却するためのものであり、第３通風路Ｔ３は、主として誘導加熱コイル５３を冷却するためのものである。さらに第２通風路Ｔ２、第３通風路Ｔ３は、誘導加熱コイル５３からの熱がパンチング板４２に伝わるのを遮断するとともに、パンチング板４２の熱が誘導加熱コイル５３に伝わるのを遮断する機能も持つ。   The first, second, and third ventilation paths T1, T2, and T3 are all ventilation paths that have the intake port 51a as an air inlet and the exhaust port 51b as an air outlet. The relatively low temperature outside air sucked through the intake port 6 is branched into three ventilation paths T1, T2, and T3 and flows in parallel, and merges at the exhaust port 51b and passes through the exhaust path 20 to the lower rear surface of the housing 2. It is discharged out of the machine through the formed exhaust port 8. The first ventilation path T1 mainly cools the punching plate 42 from above, and blocks the heat from the mounting plate 45 that is heated by conduction of heat from the cooking vessel 90 from being transmitted to the punching plate 42. Is. The second ventilation path T2 is mainly for cooling the punching plate 42 from below, and the third ventilation path T3 is mainly for cooling the induction heating coil 53. Further, the second ventilation path T2 and the third ventilation path T3 function to block the heat from the induction heating coil 53 from being transmitted to the punching plate 42 and to block the heat from the punching plate 42 from being transmitted to the induction heating coil 53. Also have.

上記構成の誘導加熱ユニット５０において、図示しない誘導加熱コイル駆動用インバータ回路から誘導加熱コイル５３に高周波電流が供給されると交番磁束が発生する。その磁束はパンチング板４２及び載置板４５を通過して調理庫４内に侵入し、少なくとも底部が磁性金属で形成された調理容器９０の底部を横切る。その誘導作用によって調理容器９０の底部に渦電流を誘起させ、ジュール熱により該調理容器９０を加熱し、その調理容器９０内に収容されている調理対象の食品を加熱する。   In the induction heating unit 50 configured as described above, when a high frequency current is supplied to the induction heating coil 53 from an induction heating coil driving inverter circuit (not shown), an alternating magnetic flux is generated. The magnetic flux passes through the punching plate 42 and the mounting plate 45 and enters the cooking chamber 4, and at least crosses the bottom of the cooking container 90 whose bottom is formed of magnetic metal. An eddy current is induced at the bottom of the cooking container 90 by the induction action, the cooking container 90 is heated by Joule heat, and the food to be cooked accommodated in the cooking container 90 is heated.

パンチング板４２は誘導加熱コイル５３から発生する磁束を通過させるために多数の小孔が形成され、またその板厚も薄くなっているが、磁束の一部はパンチング板４２を貫通する際に渦電流を誘起し、その電流損によってパンチング板４２の温度は上昇する。また、誘導加熱コイル５３自体はそのコイルを流れる電流の電流損により発熱するし、載置板４５はそれ自体は発熱しにくいものの調理容器９０からの熱伝導によって温度が上昇するから、パンチング板４２は誘導加熱コイル５３や載置板４５からの輻射熱も受ける。特に例えば業務用途のように装置の使用頻度が高い場合には、熱が蓄積されて温度が高くなり易い。これに対し本実施例の加熱調理装置１では、第１乃至第３通風路Ｔ１、Ｔ２、Ｔ３を通る空気流によりパンチング板４２を効率良く冷却し、また輻射熱の影響を軽減することができるので、その温度の上昇を抑制することができる。また、第３通風路Ｔ３を通る空気流により誘導加熱コイル５３を効率良く冷却することができるので、その温度の上昇も抑制することができる。   The punching plate 42 is formed with a large number of small holes for allowing the magnetic flux generated from the induction heating coil 53 to pass therethrough, and the plate thickness thereof is thin. However, a part of the magnetic flux is vortexed when penetrating the punching plate 42. A current is induced, and the temperature of the punching plate 42 increases due to the current loss. In addition, the induction heating coil 53 itself generates heat due to the current loss of the current flowing through the coil, and the mounting plate 45 does not generate heat itself, but the temperature rises due to heat conduction from the cooking vessel 90, so the punching plate 42. Also receives radiant heat from the induction heating coil 53 and the mounting plate 45. In particular, when the frequency of use of the apparatus is high, for example, for business use, heat is accumulated and the temperature tends to increase. On the other hand, in the cooking device 1 of the present embodiment, the punching plate 42 can be efficiently cooled by the air flow passing through the first to third ventilation paths T1, T2, T3, and the influence of radiant heat can be reduced. The temperature rise can be suppressed. Moreover, since the induction heating coil 53 can be efficiently cooled by the airflow passing through the third ventilation path T3, the temperature rise can also be suppressed.

また、パンチング板４２が温度上昇して熱膨張により上方側に凸形状に反ろうとしても、第１通風路Ｔ１内において、放射状に複数設けられた延出片４３ｂはこの反りをその全周についてほぼ均等に押さえる。そのため、パンチング板４２は反ることがなく、パンチング板４２が載置板４５の下面に接触したり、載置板４５上の調理容器９０の底面とパンチング板４２との離間距離が縮まったりすることを防止することができる。この延出片４３ｂは第１通風路Ｔ１内に突出しているため、通風路Ｔ１を通って吸気口５１ａから排気口５１ｂに向かう空気流にとっては流れ抵抗となり得るが、内周側では延出片４３ｂの端部は開放しているのでその流れ抵抗を小さくして、スムーズな空気流を確保することができる。   Further, even if the punching plate 42 rises in temperature and tends to warp upward due to thermal expansion, the extended pieces 43b provided in a plurality of radial shapes in the first ventilation path T1 will cause this warp over its entire circumference. Hold almost evenly. Therefore, the punching plate 42 does not warp, and the punching plate 42 contacts the lower surface of the mounting plate 45, or the distance between the bottom surface of the cooking container 90 on the mounting plate 45 and the punching plate 42 is reduced. This can be prevented. Since the extended piece 43b protrudes into the first ventilation path T1, it can be a flow resistance for the air flow from the intake port 51a to the exhaust port 51b through the ventilation path T1, but the extended piece on the inner peripheral side. Since the end of 43b is open, the flow resistance can be reduced and a smooth air flow can be ensured.

また、第１通風路Ｔ１は上部第１絶縁部材４３、上部第２絶縁部材４４の同一の外径で決まる平面面積のうちの５０％以上の面積を占めるように構成されている。これにより、誘導加熱ユニット冷却ファンユニット５２により吸引された空気は第１通風路Ｔ１内を良好に流れ、パンチング板４２の温度上昇を抑えるのに有効である。   The first ventilation path T1 is configured to occupy an area of 50% or more of the planar area determined by the same outer diameter of the upper first insulating member 43 and the upper second insulating member 44. Thereby, the air sucked by the induction heating unit cooling fan unit 52 flows favorably in the first ventilation path T1 and is effective in suppressing the temperature rise of the punching plate 42.

また、調理庫４の底面部４ｄは矩形状であって誘導加熱コイル５３外形は扁平円筒形状であるため、調理庫４の底面部４ｄのコーナーの下方はデッドスペースになり易いが、前面右側のコーナーの下方に吸気口５１ａ及び誘導加熱ユニット冷却ファンユニット５２を設け、それと対角である底面部４ｄの後面左側のコーナーの下方に排気口５１ｂを設けるようにしたので、デッドスペースを有効に利用して調理庫４のサイズを必要以上に大きくする必要がない。   Also, since the bottom surface portion 4d of the cooking chamber 4 is rectangular and the outer shape of the induction heating coil 53 is a flat cylindrical shape, the bottom of the bottom surface portion 4d of the cooking chamber 4 tends to be a dead space. Since the intake port 51a and the induction heating unit cooling fan unit 52 are provided below the corner, and the exhaust port 51b is provided below the left corner of the rear surface of the bottom surface portion 4d, the dead space is effectively used. And it is not necessary to enlarge the size of the cooking chamber 4 more than necessary.

なお、上部第１絶縁部材４３の変形例として、図１４に斜視図を示すようなものを利用してもよい。図１４（ａ）に示す上部第１絶縁部材４３Ａは、円環部４３ａの内方に放射状でなく櫛形状に反り抑制用の延出片４３ｂを設けた構造を有する。各延出片４３ｂはほぼ平行に並んでおり、その延伸方向が吸気口５１ａから排気口５１ｂに向かう空気流の方向と一致するように、この上部第１絶縁部材４３は装着される。これにより、延出片４３ｂはパンチング板４２の反りを押さえる作用を有しつつ、第１通風路Ｔ１内の空気流の方向を揃えて円滑な流れを確保する整流作用も発揮する。   In addition, as a modification of the upper first insulating member 43, a member shown in a perspective view in FIG. 14 may be used. The upper first insulating member 43A shown in FIG. 14A has a structure in which extending pieces 43b for suppressing warpage are provided in a comb shape instead of radially inside the annular portion 43a. The extending pieces 43b are arranged substantially in parallel, and the upper first insulating member 43 is mounted so that the extending direction thereof coincides with the direction of the air flow from the intake port 51a to the exhaust port 51b. As a result, the extending piece 43b exerts an action of suppressing the warp of the punching plate 42 and also exhibits a rectifying action of ensuring a smooth flow by aligning the direction of the air flow in the first ventilation path T1.

また図１４（ｂ）に示す上部第１絶縁部材４３Ｂは、円板状体４３ｃの外周縁が開放した放射状のスリット４３ｄが形成された構造を有する。この構造では、第１通風路Ｔ１の高さ方向のサイズが小さくなるものの、パンチング板４２の反りを押さえる作用を高めることができる。   Further, the upper first insulating member 43B shown in FIG. 14B has a structure in which radial slits 43d in which the outer peripheral edge of the disc-like body 43c is opened are formed. In this structure, although the size of the first ventilation path T1 in the height direction is reduced, the action of suppressing the warping of the punching plate 42 can be enhanced.

上述のように本実施例の加熱調理装置１では、加熱源として誘導加熱コイル５３とマグネトロン１０とを有するが、これらを駆動するインバータ回路も独立に設けられている。そのため、誘導加熱運転と高周波加熱運転とを同時並行的に行うことができ、それによって調理時間を短縮することができる。もちろん、同時加熱以外に、誘導加熱運転と高周波加熱運転のそれぞれの単独運転や、両者の交互の運転も可能である。さらには、同時運転、単独運転又は交互運転などをそれぞれ１つのステージとして、複数ステージを自在に組み合わせた複数ステージ運転を行うこともできる。   As described above, the heating cooking apparatus 1 of the present embodiment includes the induction heating coil 53 and the magnetron 10 as heating sources, but an inverter circuit for driving these is also provided independently. Therefore, the induction heating operation and the high frequency heating operation can be performed in parallel, thereby shortening the cooking time. Of course, in addition to simultaneous heating, independent operation of induction heating operation and high-frequency heating operation or alternate operation of both are also possible. Furthermore, it is also possible to perform a multi-stage operation in which a plurality of stages are freely combined, with simultaneous operation, single operation or alternating operation as one stage.

上記のようなインバータ回路は電力用スイッチング素子（例えば電力用ＦＥＴなど）を含んでおり、動作時の発熱量が大きいために放熱を適切に行う必要がある。例えば誘導加熱コイル駆動用のインバータ回路の冷却は上述した誘導加熱コイル５３やパンチング板４２の冷却を行うファンによる送風を用いても行うことは可能であるが、両方を兼用すると、いずれもが十分な冷却効果を得られず、温度が高くなり過ぎる場合がある。そこで、この実施例の加熱調理装置１では、上述した誘導加熱ユニット冷却用のファン及び通風路とは別に、誘導加熱コイル駆動用インバータ回路を冷却するためのファン及び通風路を設けている。この構造について、図１及び図７により説明する。   The inverter circuit as described above includes a power switching element (for example, a power FET). Since the amount of heat generated during operation is large, it is necessary to appropriately dissipate heat. For example, the cooling of the inverter circuit for driving the induction heating coil can be performed by using the air blow by the fan for cooling the induction heating coil 53 and the punching plate 42 described above, but if both are used, both are sufficient. The cooling effect may not be obtained and the temperature may become too high. Therefore, in the heating cooking apparatus 1 of this embodiment, a fan and a ventilation path for cooling the induction heating coil driving inverter circuit are provided in addition to the above-described induction heating unit cooling fan and ventilation path. This structure will be described with reference to FIGS.

外気取入口７は筐体２の右側面の前方に縦方向に長く形成され、この外気取入口７に連通する通風路２１は筐体２の右側面の内方を後方に延伸するように形成されている。この通風路２１の後部で調理庫４の後方側に、誘導加熱コイル駆動用インバータ冷却ファン２２が配置されている。このファン２２の作動によって外気取入口７から吸い込まれた相対的に低温の外気は、図７中に矢印で示すように、ファン２２の位置まで通風路２１内を後方に向かって流れ、その後、左方向に向きを変えて誘導加熱コイル駆動用インバータ回路が搭載された回路基板が収容されている回路ボックス２３内を通過し、筐体２の左側面内側で後方側に屈曲して排気管２４を経て筐体２の後面の排気口９から機外に排出される。   The outside air inlet 7 is formed long in the longitudinal direction in front of the right side surface of the housing 2, and the ventilation path 21 communicating with the outside air inlet 7 is formed so as to extend backward inward of the right side surface of the housing 2. Has been. An inverter cooling fan 22 for driving the induction heating coil is disposed behind the cooking chamber 4 at the rear of the ventilation path 21. The relatively low temperature outside air sucked from the outside air inlet 7 by the operation of the fan 22 flows backward in the ventilation path 21 to the position of the fan 22, as indicated by an arrow in FIG. The direction is changed to the left and passes through the circuit box 23 in which the circuit board on which the inverter circuit for driving the induction heating coil is mounted is accommodated. Then, the air is discharged from the exhaust port 9 on the rear surface of the housing 2 to the outside of the apparatus.

誘導加熱を行う際に誘導加熱コイル駆動用インバータ回路は発熱するが、上記のように誘導加熱コイル５３やパンチング板４２などの冷却とは別の経路で、誘導加熱コイル駆動用インバータ冷却ファン２２の動作によって空気が流れることにより、効率良く放熱が行われる。これにより、誘導加熱コイル駆動用インバータ回路などの異常な温度上昇を回避することができる。   The induction heating coil driving inverter circuit generates heat when induction heating is performed, but the induction heating coil driving inverter cooling fan 22 is not connected to the induction heating coil 53 or the punching plate 42 as described above. Heat is efficiently radiated by air flowing through the operation. Thereby, abnormal temperature rises, such as an induction heating coil drive inverter circuit, can be avoided.

次に、本実施例の加熱調理装置１の調理庫内の空気を機外に排出する排気構造について図９〜図１２を参照して説明する。図９は本実施例の加熱調理装置において排気内筒蓋を外した状態での外観斜視図、図１０は排気内筒を引き出した状態での外観斜視図、図１１は排気内筒を含む排気構造の斜視図、図１２は本実施例の加熱調理装置の背面側の外観斜視図である。   Next, an exhaust structure for discharging the air in the cooking chamber of the heating cooking apparatus 1 of the present embodiment to the outside of the apparatus will be described with reference to FIGS. 9 is an external perspective view of the cooking device of the present embodiment with the exhaust inner cylinder lid removed, FIG. 10 is an external perspective view of the exhaust inner cylinder with the exhaust pipe pulled out, and FIG. 11 is an exhaust including the exhaust inner cylinder. FIG. 12 is an external perspective view of the rear side of the cooking device according to the present embodiment.

加熱調理に際し調理庫４内では食品から油煙や蒸気などが発生するから、これを機外に排出するために、調理庫４の後壁面の左方上部に設けられた庫内排気口３０（図１６参照）からほぼ真っ直ぐ後方に向かって排気ダクト３１が形成され、筐体２の後面に形成された排気口３２に接続されている。さらに、図２に示すように、筐体２の左側面に設けられている排気内筒蓋３３を開けると、その内側には図１０に示すように左方に引き出して取り外し可能な排気内筒部材３４が配設されている。排気内筒部材３４は、図１１に示すように、引き出しの際に把持する把手３４ａと内面が四角筒状の内筒部３４ｂを有し、図９及び図１１に示すように装置に装着された状態では排気ダクト３１の内側に内筒部３４ｂが嵌る。   In the cooking chamber 4 during cooking, oil smoke or steam is generated from the food. In order to discharge it outside the machine, the internal exhaust port 30 (see FIG. 16), an exhaust duct 31 is formed substantially straight rearward, and is connected to an exhaust port 32 formed on the rear surface of the housing 2. Further, as shown in FIG. 2, when the exhaust inner cylinder lid 33 provided on the left side surface of the housing 2 is opened, the exhaust inner cylinder that can be pulled out to the left and removed as shown in FIG. A member 34 is disposed. As shown in FIG. 11, the exhaust inner cylinder member 34 has a handle 34a to be gripped when being pulled out and an inner cylinder part 34b whose inner surface is a square cylinder, and is mounted on the apparatus as shown in FIGS. In this state, the inner cylinder part 34 b fits inside the exhaust duct 31.

即ち、この内筒部３４ｂ内を排気が通過するようになっているから、排気に含まれる油や煤などの汚れは排気ダクト３１の内面ではなく内筒部３４ｂの内面に付着する。排気内筒部材３４は着脱可能であるため、図１０に示すように排気内筒部材３４を引き出して取り外すことで、内筒部３４ｂの内面を簡単に掃除することができる。また、場合によっては、排気内筒部材３４のみを新品に交換することもできる。これにより、加熱調理装置１自体に固定された排気ダクト３１の内面を掃除する手間が軽減される。   That is, since the exhaust gas passes through the inner cylinder part 34b, dirt such as oil and soot contained in the exhaust gas adheres to the inner surface of the inner cylinder part 34b instead of the inner surface of the exhaust duct 31. Since the exhaust inner cylinder member 34 is detachable, the inner surface of the inner cylinder part 34b can be easily cleaned by pulling out and removing the exhaust inner cylinder member 34 as shown in FIG. In some cases, only the exhaust inner cylinder member 34 can be replaced with a new one. Thereby, the effort which cleans the inner surface of the exhaust duct 31 fixed to the heating cooking apparatus 1 itself is reduced.

なお、排気内筒部材３４の引き出し方向に延伸するように排気温度検出用の温度センサ３５が装置１側に取り付けられ、排気内筒部材３４の内筒部３４ｂの壁面にはこの温度センサ３５が挿通する孔３４ｃが形成されている。それにより、排気内筒部材３４を装置１に装着すると、温度センサ３５は孔３４ｃに挿通され、その先端部は内筒部３４ｂの内側に突出する。したがって、この温度センサ３５により排気の温度を検出することができ、例えば調理庫４内での食品等の異常加熱（例えば異常な焦げなど）を検知することができる。   A temperature sensor 35 for detecting the exhaust temperature is attached to the apparatus 1 so as to extend in the direction in which the exhaust inner cylinder member 34 is pulled out, and this temperature sensor 35 is attached to the wall surface of the inner cylinder portion 34b of the exhaust inner cylinder member 34. An insertion hole 34c is formed. As a result, when the exhaust inner cylinder member 34 is attached to the apparatus 1, the temperature sensor 35 is inserted into the hole 34c, and the tip thereof protrudes inside the inner cylinder 34b. Accordingly, the temperature of the exhaust gas can be detected by the temperature sensor 35, and for example, abnormal heating of the food or the like in the cooking chamber 4 (for example, abnormal burning) can be detected.

なお、この加熱調理装置１を設置する場合に、筐体２の後面の後方に十分な空間を確保できれば排気口８から機外への排気は行われ易いが、十分な空間が確保できないと排気量も小さくなるおそれがある。そうした場合には、外付けの冷却用ファン装置を設けることができる。その冷却用ファン装置に電力を供給するための電力出力端子が筐体２の後面に配設されている。即ち、図１２に示すように、筐体２の後面にネジで取り付けられている端子蓋３６を開けると、その内側に電力出力端子３７が露出し、ここに冷却用ファン装置等の電源ソケットを差し込むようにすることができる。   In addition, when this heating cooking apparatus 1 is installed, if sufficient space can be secured behind the rear surface of the housing 2, exhaust from the exhaust port 8 to the outside of the apparatus is easy to be performed, but if sufficient space cannot be secured, exhaust is performed. The amount may also be reduced. In such a case, an external cooling fan device can be provided. A power output terminal for supplying power to the cooling fan device is disposed on the rear surface of the housing 2. That is, as shown in FIG. 12, when the terminal lid 36 attached to the rear surface of the housing 2 with a screw is opened, the power output terminal 37 is exposed on the inside, and a power socket such as a cooling fan device is provided here. Can be plugged in.

この電力出力端子３７により出力される電力は誘導加熱ユニット冷却ファンユニット５２の冷却ファンモータの動作と連動してオン／オフされる。したがって、誘導加熱ユニット冷却ファンユニット５２の冷却ファンモータが作動する際に外付け冷却用ファン装置も動作し、内蔵の冷却ファンモータの運転停止時には外付け冷却用ファン装置も停止するようにすることができる。これにより、内蔵の冷却ファンだけでは十分な風量を確保することが難しい場合でも、上述したような第１乃至第３通風路Ｔ１、Ｔ２、Ｔ３などに十分な空気流を生起させて、誘導加熱コイル５３やパンチング板４２の温度上昇を防止することができる。   The power output from the power output terminal 37 is turned on / off in conjunction with the operation of the cooling fan motor of the induction heating unit cooling fan unit 52. Therefore, when the cooling fan motor of the induction heating unit cooling fan unit 52 is operated, the external cooling fan device is also operated, and when the operation of the built-in cooling fan motor is stopped, the external cooling fan device is also stopped. Can do. As a result, even when it is difficult to secure a sufficient air flow with only the built-in cooling fan, a sufficient air flow is generated in the first to third ventilation paths T1, T2, T3 and the like as described above to induce induction heating. The temperature rise of the coil 53 and the punching plate 42 can be prevented.

次に、本実施例の加熱調理装置１において調理容器９０を前後に移動させる容器移動機構（本発明における容器保持手段）について図１３を参照して説明する。図１３（ａ−１）、（ｂ−１）は調理庫４の底面構造と容器移動機構の上面図、図１３（ａ−２）、（ｂ−２）はＡ−Ａ’矢視線での側面断面図である。この容器移動機構は、調理容器９０を保持する開口が形成された略平板状の容器支持体（本発明における容器支持手段に相当）９１と、調理庫４の両側面に取り付けられ、容器支持体９１の左右両側縁部を上下から挟み込むように保持しつつ、前後方向に案内する案内レール（本発明における案内手段に相当）９２とから成る。容器支持体９１はセラミック等の絶縁体から成る。   Next, a container moving mechanism (container holding means in the present invention) that moves the cooking container 90 back and forth in the heating cooking apparatus 1 of the present embodiment will be described with reference to FIG. 13 (a-1) and (b-1) are top views of the bottom structure of the cooking cabinet 4 and the container moving mechanism, and FIGS. 13 (a-2) and (b-2) are taken along the line AA ′. It is side surface sectional drawing. The container moving mechanism is attached to both sides of the substantially flat container support 91 (corresponding to the container support means in the present invention) 91 in which an opening for holding the cooking container 90 is formed, and the container support. A guide rail (corresponding to the guide means in the present invention) 92 that guides in the front-rear direction while holding the left and right side edges of 91 from above and below. The container support 91 is made of an insulator such as ceramic.

案内レール９２は後方から前方に向かって緩やかな上傾斜になっており、この案内レール９２に保持される容器支持体９１はそれ自体が同様に斜めに傾いた状態で前後方向に移動自在である。案内レール９２の後端にはストッパ９２ａが形成されていて、容器支持体９１の側縁部の窪み９１ａがこのストッパ９２ａに当接することで容器支持体９１の最後部の位置が規制される。調理容器９０が容器支持体９１に保持された状態であるとき、容器支持体９１が上述のように斜めの姿勢において調理容器９０の底面は水平、つまりは載置板４５の上面と水平になっている。容器支持体９１が最後部の規制位置にあるとき、調理容器９０の底面は載置板４５の上面に接している。また、このとき、調理容器９０の位置はちょうど誘導加熱コイル５３の上方になっている。したがって、誘導加熱が最も良好に行われる状態である。   The guide rail 92 has a gentle upward inclination from the rear to the front, and the container support 91 held by the guide rail 92 is movable in the front-rear direction in a state where the guide support 92 is also inclined in the same manner. . A stopper 92a is formed at the rear end of the guide rail 92, and the position of the rearmost portion of the container support 91 is restricted by the depression 91a at the side edge of the container support 91 coming into contact with the stopper 92a. When the cooking container 90 is held by the container support 91, the bottom surface of the cooking container 90 is horizontal, that is, the top surface of the mounting plate 45 when the container support 91 is inclined as described above. ing. When the container support 91 is in the last restriction position, the bottom surface of the cooking container 90 is in contact with the top surface of the mounting plate 45. At this time, the position of the cooking container 90 is just above the induction heating coil 53. Therefore, the induction heating is most preferably performed.

一方、容器支持体９１が案内レール９２に沿って前方に移動されると、調理容器９０の底面は水平状態を維持したまま前方に移動するとともに少し上方に移動する。したがって、調理容器９０の前半分程度が調理庫４よりも前方に飛び出し、しかもその位置は上昇するので、調理容器９０への食品の出し入れが非常に容易である。また、調理容器９０を容器支持体９１から取り外すのも容易である。   On the other hand, when the container support 91 is moved forward along the guide rail 92, the bottom surface of the cooking container 90 moves forward while being kept in a horizontal state and slightly moved upward. Therefore, the front half of the cooking container 90 jumps forward from the cooking chamber 4 and the position thereof rises, so that the food can be taken into and out of the cooking container 90 very easily. It is also easy to remove the cooking container 90 from the container support 91.

このように本実施例の加熱調理装置１では容器支持体９１に所定の調理容器９０を装着して後方まで押し入れることで、誘導加熱の効率が最良になるような位置に調理容器９０をセットすることができる。一方、容器支持体９１を前方に引き出すことで調理容器９０への食品の出し入れを容易に且つ高い安全性を確保して行うようにすることができる。   Thus, in the heating cooking apparatus 1 of the present embodiment, the cooking container 90 is set at a position where the efficiency of induction heating becomes the best by attaching the predetermined cooking container 90 to the container support 91 and pushing it backward. can do. On the other hand, by pulling the container support 91 forward, food can be taken in and out of the cooking container 90 easily and with high safety.

なお、上記説明では、特定の形状の調理容器を用いる場合の例であるが、容器移動機構を用いずに底面が円形状の鍋９５を利用する場合には、図１５に示すように、その略中央に円形状の窪み４５ｂを形成した載置板４５Ａを利用するとよい。   In the above description, a cooking container having a specific shape is used. However, when a pan 95 having a circular bottom is used without using the container moving mechanism, as shown in FIG. A mounting plate 45A in which a circular recess 45b is formed in the approximate center may be used.

また、上述のように容器移動機構を用いた場合には、金属製である調理容器が調理庫４の後壁面や側壁面に当接することはないが、図１５に示したように単に鍋等の調理容器を調理庫４内に置くだけの場合には、調理容器が調理庫４の後壁面や側壁面に当接する可能性がある。そこで、これを避けるために、調理庫４の後面部４ｂ、左側面部４ｅ及び右側面部４ｆに平板状の絶縁部材を装着するとよい。具体例として図１６に調理庫４内部を覗いた図を示す。   Further, when the container moving mechanism is used as described above, the cooking container made of metal does not come into contact with the rear wall surface or the side wall surface of the cooking chamber 4, but as shown in FIG. When the cooking container is simply placed in the cooking chamber 4, the cooking container may come into contact with the rear wall surface or the side wall surface of the cooking chamber 4. Therefore, in order to avoid this, a flat plate-like insulating member may be attached to the rear surface portion 4b, the left side surface portion 4e, and the right side surface portion 4f of the cooking chamber 4. As a specific example, FIG. 16 shows a view of the inside of the cooking cabinet 4.

この例では、調理庫４の後面部４ｂ、左側面部４ｅ及び右側面部４ｆの上側のコーナー付近にそれぞれ一対のフック８０が設けられており、このフック８０に絶縁板部材８１を引掛けるようにして取り付ける。フック８０は金属製又は合成樹脂製である。一方、絶縁板部材８１はマイクロ波に影響を及ぼさない材料、例えばガラス積層板にシリコーンを含浸したものとすることができる。これにより、調理容器が調理庫４内で片寄った位置に置かれても該容器が調理庫４の内壁面に直接的に接触することを防止することができる。また、必要に応じてこの絶縁板部材８１を取り外すことができる。   In this example, a pair of hooks 80 are provided in the vicinity of the upper corners of the rear surface portion 4b, the left side surface portion 4e, and the right side surface portion 4f of the cooking cabinet 4, and an insulating plate member 81 is hooked on the hook 80. Install. The hook 80 is made of metal or synthetic resin. On the other hand, the insulating plate member 81 can be made of a material that does not affect the microwave, for example, a glass laminated plate impregnated with silicone. Thereby, even if it puts in the position where the cooking container deviated in the cooking chamber 4, it can prevent that this container contacts the inner wall face of the cooking chamber 4 directly. Further, the insulating plate member 81 can be removed as necessary.

なお、上記実施例はいずれも本発明の一例にすぎず、本発明の趣旨の範囲で適宜、変形、修正又は追加などを行っても本願特許請求の範囲に包含されることは明らかである。   The above-described embodiments are merely examples of the present invention, and it is obvious that modifications, additions, additions, and the like as appropriate within the scope of the present invention are included in the scope of the claims of the present application.
