Description

【０００１】
【発明の属する技術分野】
本発明はロースターを備える単一または複合の加熱調理器に関し、特に自動調理機能または除煙機能を有するものに関する。
【０００２】
【従来の技術】
従来この種の加熱調理器として、発熱体により加熱された被調理物から発生する煙を発熱体により加熱された触媒体を通過させることで浄化促進して外に排出するようなものがあった。（例えば、特許文献１参照）。
【０００３】
図６において、１０１は加熱調理器の外郭を構成する本体であり、１０２は本体１０１内に構成されたグリル庫であり、１０３はグリル庫１０２の上部を形成する上部容器であり、１０４は上部容器１０３の略中央上面に配設した開口穴であり、１０５は開口穴１０４と連結した触媒体であり、１０６は触媒体の下方に配設した発熱体であり、１０７はグリル庫１０２内に載置した焼き網であり、１０８は焼き網１０７に載置した被調理物である。発熱体１０６は被調理物１０８の相対面を加熱し、使用者が所定の時間を手動で決定し、被調理物１０８をひっくり返して再度発熱体１０６により加熱する構成としている。
【０００４】
また、このとき発生する煙は開口穴１０４に向かって触媒体１０５を通過してから開口穴１０４を抜け、外に排出される構成としている。また、発熱体１０６は触媒体１０５の煙の浄化作用を促進するための加熱を兼ねた構成としている。
【０００５】
前記従来構成において、発熱体１０６により加熱された被調理物１０８から発生する煙は、同じく発熱体１０６により加熱された触媒体１０５を通過することで浄化促進され外に排出し、台所などの空気を汚さず調理できるというものであった。
【０００６】
【特許文献１】

【０００７】
【発明が解決しようとする課題】
しかしこのような構成の加熱調理器では、調理性能と除煙性能を両立して優れた性能を確保することが困難で、例えば触媒体１０５の煙の浄化促進温度４５０℃以上に速くしかも均一的に到達させなければ、除煙率が低くなるため発熱体１０６をできるだけ触媒体１０５に近づけようとし、そのため上部容器１０３または本体１０１が高温にさらされ使用性の悪いものになり、発熱体１０６を部分的に触媒体１０５に近づける形状にすると、発熱体１０６は被調理物１０８から部分的に遠ざかり、焼きむらなど調理性能が悪くなるものであった。
【０００８】
また、被調理物１０８の大きさに合わせた発熱体１０６から焼き網１０７までの有効高さ寸法は、使用者にとってできるだけ大きいほうが使い勝手がよく、発熱体１０６の上方に触媒体１０５を構成する前記従来構成では本体１０１の高さ寸法が大きくなり、使い勝手が悪く、またロースター付の誘導加熱調理器のような複合商品では、本体１０１の上方に誘導加熱部を構成しなければならず、限られたスペースの中で前記従来構成を実現できないものであった。
【０００９】
また、被調理物の量や大きさ、種類などに応じた自動調理ができない構成で、使い勝手に優れ、快適な調理を実現できるロースターを備えた加熱調理器を提供することは困難であった。
【００１０】
【課題を解決するための手段】
前記従来の課題を解決するために本発明は、外郭を構成する本体と、前記本体内に収納され前面をドア体で密閉するグリル庫と、前記グリル庫の背面に配設したグリル庫開口穴と連結した排気筒開口穴を有する筒状の排気筒とを備え、前記グリル庫内において被調理物の下方に設けられて前記被加熱物を加熱する発熱体の一部である触媒加熱部が、前記排気筒の煙の流路を塞ぐように形成された触媒体の下面に沿いかつ前記触媒体の風上近傍に形成されるとともに、前記排気筒内の前記触媒加熱部下方に、前記被調理物の負荷量を温度で検知する負荷量検知装置が固定され、前記排気筒の出口は前記本体上面に配設されて前記本体の外に向けられた構成とした。この構成により調理性能および除煙性能に優れた、自動調理が実現できる加熱調理器を提供するものである。
【００１１】
【発明の実施形態】
本発明の請求項１記載の発明は、外郭を構成する本体と、前記本体内に収納され前面をドア体で密閉するグリル庫と、前記グリル庫の背面に配設したグリル庫開口穴と連結した排気筒開口部を有する筒状の排気筒とを備え、前記グリル庫内において被調理物の下方に設けられて前記被加熱物を加熱る発熱体の一部である触媒加熱部が、前記排気筒の煙の流路を塞ぐように形成された触媒体の下面に沿いかつ前記触媒体の風上近傍に形成されるとともに、前記排気筒内の前記触媒加熱部下方に、前記被調理物の負荷量を温度で検知する負荷量検知装置が固定され、前記排気筒の出口は前記本体上面に配設されて前記本体の外に向けられた構成とすることで、グリル庫内の高さ寸法を大きく確保でき、グリル庫内に位置する発熱体は負荷量検知装置の温度検知に悪影響を及ぼすことなく、焼むらの少ない調理性能を確保しつつ、発熱体の一部である触媒加熱部の形状をフレキシブルに決め、触媒体との距離を近づける構成とすることができ、煙に対して触媒体が均一に浄化促進温度に達する速度を速めることができ、除煙効率を向上することができる。
【００１２】
本発明の請求項２記載の発明は、外郭を構成する本体と、前記本体内に収納され前面をドア体で密閉するグリル庫と、前記グリル庫の背面に配設したグリル庫開口穴と連結した排気筒開口穴を有する筒状の排気筒とを備え、前記グリル庫内において被調理物の下方に設けられて前記被加熱物を加熱する発熱体の一部である触媒加熱部が、前記排気筒の煙の流路を塞ぐように形成された触媒体の下面に沿いかつ前記触媒体の風上近傍に形成されるとともに、前記排気筒開口穴を二つに分割する仕切り板で遮蔽して前記排気筒内に形成した一方の主部屋内に前記触媒体と前記触媒加熱部が配設され、前記仕切り板で遮蔽して前記排気筒開口以外を隔離して設けた他方の副部屋内に前記被調理物の負荷量を温度で検知する負荷量検知装置が配設され、前記排気筒の出口は前記本体上面に配設されて前記本体の外に向けられたことで、負荷量検知装置に対する触媒加熱部からの輻射熱の影響を軽減し、被調理物の量や大きさ、種類などの違いを温度で検知して精度よく、安定した自動調理を実現できる。
【００１３】
本発明の請求項３記載の発明は、特に、仕切り板には副部屋に進入した煙を主部屋に導通するための流路が形成されていることで、煙の停滞を防ぎ損失なく煙を主部屋に導くことができ、除煙性能を低下させずに自動調理を実現することができる。
【００１４】
【実施例】
（実施例１）
以下に本発明の実施例１について図１を参照して説明する。図１は本発明の実施例１における加熱調理器の断面図を示す。
【００１５】
図１において、本体１は本発明の加熱調理器の外郭を構成し箱体のグリル庫２を載置、固定して収納している。グリル庫２の前面開口部１５は、開閉自在のドア３により密閉され、グリル庫２の背面に開けられたグリル庫開口穴４に連結して排気筒開口穴６が配設され、排気筒５が取り付けられ排気口７が本体開口穴１６に連結するように構成している。排気筒５の煙の流路を塞ぐように排気筒５の中に触媒８が固定され、触媒８の下方に負荷量検知装置１４が固定され、制御部１９に配線されている。
【００１６】
次にグリル庫２の内部には汁や油を受ける受け皿１１に載置された焼き網１２の上に被調理物１３が載置される。被調理物１３の上方には上ヒータ９が、被調理物１３の下方には下ヒータ１０が任意の距離だけ間隔をおいて、グリル庫２の背面の上端末固定部２０と下端末固定部２１でそれぞれ固定され、制御部１９に配線されている。上ヒータ９の発熱部の一部である上触媒加熱部１７は、触媒８の側面に沿って発熱面積を大きく確保するよう形成され、下ヒータ１０の発熱部の一部である下触媒加熱部１８は触媒８の下面に沿って発熱面積を大きく確保するように形成され、いずれも煙の流路の風上から触媒を効率よく加熱するよう構成している。
【００１７】
なお、上ヒータ９と下ヒータ１０はともにシーズヒータで、上触媒加熱部１７および下触媒加熱部１８の形状は発熱面積を大きくでき、触媒８をすばやく均一に加熱できるものであればどのような形状でもよい。また、触媒８は白金を主成分とする蜂の巣状のセルを形成し、低温触媒として浄化促進温度は３５０℃以上とする。構成となっている。
【００１８】
また本実施例のように二つのヒータを同時加熱する場合、上ヒータの消費電力８００Ｗ以上、下ヒータの消費電力７００Ｗ以上が性能上望ましい。また二つのヒータの交互加熱または一つのヒータでの加熱の場合、１２００Ｗ以上が性能上望ましい。さらに、上ヒータ９と焼き網１２の間の距離は大型の鯵や鯛といった魚を調理するために、５０ｍｍ以上確保することが使い勝手向上につながる。
【００１９】
以上のように構成された加熱調理器について、以下その作用効果について説明する。
【００２０】
電源が投入され、上ヒータ９と下ヒータ１０が通電され、被調理物１３の量、大きさ、種類などによって異なる排気雰囲気の温度上昇傾向をサーミスタなどの負荷量検知装置１４で検知して、制御部１９により上ヒータ９と下ヒータ１０を加熱制御する。調理中に発生した煙は、ドア３で密閉された前面開口部１５から外には排出できず、唯一の流路となるグリル庫開口穴４を通り排気筒開口穴６を通って触媒８をほぼ１００％通過して、排気口７を抜けて本体開口穴１６から本体１の外に排出される。このとき上触媒加熱部１７と下触媒加熱部１８により、グリル庫２内部の温度上昇よりも速く触媒８の温度が上昇し、煙がグリル庫２内部に充満する前に煙の浄化促進温度である３５０℃に達することができ、自然排気構成でありながら従来７０％程度であった除煙率を約９０％以上（煙濃度：１６ｐｐｍ以下）にすることができる。
【００２１】
また、被調理物１３は上触媒加熱部１７と下触媒加熱部１８の形状に影響されず、焼むらなどの調理性能を損なうことなく、しかも負荷量検知装置１４により被調理物１３の量、大きさ、種類などの違いを温度検知して、自動制御することで最適な調理を自動で便利に実現することができる。

【００２３】
図２、図３および図４において、仕切り板４０は排気筒３５とグリル庫開口穴３４を連結している排気筒開口穴３６を二つに分割して、主部屋４４と副部屋４５を構成し、主部屋４４の煙の流路を塞ぐように触媒４１が固定されその下方の主部屋４４の内部に触媒加熱部４１が構成されている。次に副部屋４５の内部には負荷量検知装置４３が固定され、仕切り板４０により排気筒開口穴３４以外は遮蔽され、触媒加熱部４２からも遮蔽、隔離されている。
【００２４】
なお、負荷量検知装置４３は副部屋４５のどの位置に配置されてもよい。また、被調理物３９を加熱する構成は実施例１と同様である。
【００２５】
以上のように構成された加熱調理器について、以下その作用効果について説明する。
【００２６】
調理中に発生した煙は唯一の流路となる排気筒開口穴３４を仕切り板４０で分割した主部屋４０を通り、触媒４１を通過して排気口３７を抜けて本体開口穴３８から本体３１の外に排出される。仕切り板４０により煙を効率よく浄化するために加熱される触媒加熱部４２の輻射熱から、負荷量検知装置４３を遮蔽することができ、負荷量検知装置４３を精度よく安定させて動作させることができる。
【００２７】
（実施例３）
以下に本発明の実施例３について図５を参照して説明する。
【００２８】
図５は本発明の実施例３における加熱調理器の排気筒の正面図を示す。
【００２９】
図５において、仕切り板５０は、触媒加熱部５２の発熱による輻射熱から負荷量検知装置５３を遮蔽できるように上部を一部切り欠き、排気筒開口穴５６の上方に空間を設けて分割し、主部屋５４と副部屋５５とは排気筒開口穴５６の上方でつながり、その直上に触媒５１が配設されている。
【００３０】
なお、本実施例では仕切り板５０の上部を一部切り欠く構成としたが、上部に一つ以上の開口穴を設けてもよく、また仕切り板５０を覆う金属製のカバーを設けて主部屋と副部屋の境界をなくす構成としてもよい。
【００３１】
以上のように構成された加熱調理器について、以下その作用効果について説明する。
【００３２】
調理中に発生した煙は唯一の流路となる排気筒開口穴５６を仕切り板５０で分割した主部屋５４を通り、以下実施例２と同様に触媒５１を通過して外に排出される。また、副部屋５５に進入した煙は排気筒開口穴５６と仕切り板４０の隙間から主部屋５４側に流れ込み、以下実施例２と同様に触媒５１を通過して外に排出される。これにより副部屋内の煙の停滞を防ぎ、浄化の損失を防ぐことができる。また仕切り板５０により煙を効率よく浄化するために加熱される触媒加熱部４２の輻射熱から、負荷量検知装置４３を遮蔽することができ、負荷量検知装置４３を精度よく安定させて動作させることができる。
【００３３】
【発明の効果】
上記に示したように、請求項１〜３に記載の発明によれば、グリル庫内の高さ寸法を大きく確保でき、グリル庫内に位置する発熱体は負荷量検知装置の温度検知に悪影響を及ぼすことなく、焼むらの少ない調理性能を確保しつつ、発熱体の一部である触媒加熱部の形状をフレキシブルに決め、触媒体との距離を近づける構成とすることができ、煙に対して触媒体が均一に浄化促進温度に達する速度を速めることができ、除煙効率を向上することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a single or combined cooking device having a roaster, and more particularly to an automatic cooking function or a smoke removing function.
[0002]
[Prior art]
Conventionally, as this type of cooking device, there has been a type in which smoke generated from an object to be cooked heated by a heating element is passed through a catalyst body heated by a heating element to promote purification and discharged outside. . (For example, refer to Patent Document 1).
[0003]
In FIG. 6, 101 is a main body that constitutes the outline of the heating cooker, 102 is a grill box configured in the main body 101, 103 is an upper container that forms the upper part of the grill box 102, and 104 is the upper part Reference numeral 105 denotes an opening hole disposed substantially at the upper surface of the container 103, 105 denotes a catalyst body connected to the opening hole 104, 106 denotes a heating element disposed below the catalyst body, and 107 denotes a grill box 102. Reference numeral 108 denotes a grilled net, and 108 denotes an object to be cooked placed on the grill 107. The heating element 106 heats the relative surface of the object 108 to be cooked, and the user manually determines a predetermined time, and the object 108 is turned over and heated again by the heating element 106.
[0004]
Further, the smoke generated at this time passes through the catalyst body 105 toward the opening hole 104 and then passes through the opening hole 104 and is discharged outside. Further, the heating element 106 is configured to serve as heating for promoting the smoke purification action of the catalyst body 105.
[0005]
In the above-described conventional configuration, the smoke generated from the cooking object 108 heated by the heating element 106 passes through the catalyst body 105 also heated by the heating element 106 and is purified and discharged to the outside. Was able to cook without getting dirty.
[0006]
[Patent Document 1]
Japanese Utility Model Publication No. 04-21335 (Fig. 6)
[0007]
[Problems to be solved by the invention]
However, in the heating cooker having such a configuration, it is difficult to ensure excellent performance by satisfying both cooking performance and smoke removal performance. For example, the smoke purification temperature of the catalyst 105 is faster than 450 ° C. and uniform. Otherwise, the smoke removal rate will be low, so that the heating element 106 tries to be as close to the catalyst body 105 as possible, so that the upper container 103 or the main body 101 is exposed to a high temperature and becomes unusable. If the shape is made to be partially close to the catalyst body 105, the heating element 106 is partially moved away from the object to be cooked 108, and cooking performance such as uneven baking is deteriorated.
[0008]
In addition, the effective height dimension from the heating element 106 to the grill net 107 according to the size of the cooking object 108 is more convenient for the user as much as possible, and the catalyst body 105 is formed above the heating element 106. In the conventional configuration, the height of the main body 101 is large, so that it is not easy to use. In addition, in a complex product such as an induction heating cooker with a roaster, an induction heating unit must be configured above the main body 101. The conventional configuration cannot be realized in a space.
[0009]
In addition, it has been difficult to provide a heating cooker equipped with a roaster that is easy to use and can provide comfortable cooking with a configuration that does not allow automatic cooking according to the amount, size, type, and the like of the object to be cooked.
[0010]
[Means for Solving the Problems]
In order to solve the above-described conventional problems, the present invention includes a main body constituting an outer shell, a grill box housed in the main body and having a front surface sealed with a door body, and a grill box opening hole disposed on the back surface of the grill box. And a catalyst heating section that is a part of a heating element that is provided below the object to be cooked in the grill cabinet and heats the object to be heated. Formed along the lower surface of the catalyst body formed so as to block the smoke flow path of the exhaust stack and in the vicinity of the upwind of the catalyst body, and below the catalyst heating section in the exhaust stack, A load amount detection device for detecting the load amount of the food by temperature is fixed, and the outlet of the exhaust pipe is disposed on the upper surface of the main body and is directed to the outside of the main body . This configuration provides a cooking device that is excellent in cooking performance and smoke removal performance and can realize automatic cooking.
