Description

本発明は、食品加熱保温容器の改良、詳しくは、選択される容器内に収容した一部の食品のみを加熱保温することができ、また食品の加熱殺菌も充分に行うことが可能で、しかも、加熱作業時に火傷等を負う心配もなく、何度でも繰り返し使用することができる電磁誘導加熱式の食品加熱保温容器に関するものである。   The present invention is an improvement of a food heat insulation container, more specifically, only a part of the food contained in the selected container can be heated and insulated, and the food can be sufficiently heat sterilized. The present invention relates to an electromagnetic induction heating type food heating and holding container that can be used over and over without worrying about burns during heating operations.
周知のとおり、弁当などを温める際には電子レンジが用いられることが多いが、電子レンジは、食品中の水分をマイクロ波によって急激に加熱する原理を採用しているため、食品を所定の温度まで加熱したり、一定の温度で保温したりする用途には適してしない。   As is well known, a microwave oven is often used to heat a lunch box or the like, but since the microwave oven employs the principle of rapidly heating the moisture in the food by microwaves, the food is kept at a predetermined temperature. It is not suitable for applications such as heating to a constant temperature or keeping at a constant temperature.
また、上記のような食品の加熱や保温には湯煎による加熱法が好適であると考えられるが、通常の燃焼式のガスコンロを用いて湯煎を行う場合には、直接火にかける外側容器に耐熱性に優れた金属製やセラミック製(陶磁器等)の容器を使用する必要があるため、プラスチック製や木製の容器から成る弁当容器等の保温に応用することは難しい。   In addition, it is considered that a hot water heating method is suitable for heating and keeping the food as described above. However, when performing a hot water bath using a normal combustion type gas stove, heat resistance is applied to the outer container that is directly heated. Since it is necessary to use a container made of metal or ceramic (ceramics, etc.) with excellent properties, it is difficult to apply it to heat insulation of a lunch box made of plastic or wooden containers.
ところで最近では、ガスコンロよりも熱効率が良く、掃除も簡単で環境にも優しい電磁調理器(IH調理器)の普及も進んでおり、このような電磁調理器を利用した技術として、非導電性の外側容器内に電磁誘導発熱体を配置し、この発熱体を電磁調理器により水中で加熱して食品の湯煎を行う加熱方法が<特許文献1>に開示されている。   Recently, electromagnetic cookers (IH cookers) that have better thermal efficiency than gas stoves, are easy to clean, and are friendly to the environment are also becoming popular. As a technology using such an electromagnetic cooker, non-conductive <Patent Document 1> discloses a heating method in which an electromagnetic induction heating element is disposed in an outer container, and the heating element is heated in water with an electromagnetic cooker to make a hot water bath of food.
そして、このような加熱方法を用いれば、プラスチック製等の容器でも使用することができるため、内側容器と外側容器とが二重構造になった弁当容器を作製して、容器に入れた惣菜などを電磁調理器により温めることが可能となるものの、仕切り等を設けた内側容器に食品を収容しただけでは加熱時に収容した食品全てが温まってしまうことから、加熱されると風味が落ちる冷菜やデザート等を収容することができず、実用性に欠けていた。   And if such a heating method is used, since it can be used even in containers made of plastic, etc., a lunch box container in which the inner container and the outer container have a double structure is prepared, and the side dish etc. put in the container Can be heated with an electromagnetic cooker, but if you only store food in an inner container with a partition, etc., all the food stored during heating will be warmed. Desserts could not be accommodated and lacked practicality.
一方、従来においては、<特許文献2>にあるような弁当箱の底部に蓄熱体を配置して一部の食品のみを加熱保温する技術も提案されていたが、電子レンジで加熱した蓄熱体を弁当箱に差し込む作業に火傷の危険が伴う上に、底部のみからの加熱ではどうしても加熱ムラが生じて食品の加熱殺菌を充分に行えないという問題があった。   On the other hand, in the prior art, a technique for heating and keeping only a part of food by arranging a heat storage body at the bottom of the lunch box as described in <Patent Document 2> has been proposed. In addition to the risk of burns in the operation of inserting the food into the lunch box, heating from the bottom alone inevitably causes uneven heating, and the food cannot be sufficiently sterilized by heating.
しかも、加熱源として使用する蓄熱体は使用回数に制限があり定期的に買い替える必要があったため、大量の弁当を取り扱う病院食や学校給食などの調理現場では、コスト負担が大きくなって不経済になり易かった。   In addition, the heat storage used as a heating source has a limited number of uses and must be replaced regularly, which makes the cost burden large and uneconomical at cooking sites such as hospital meals and school lunches that handle large amounts of lunch boxes. It was easy.

本発明は、上記の如き問題に鑑みて為されたものであり、その目的とするところは、任意に選択された容器内に収容する食品のみを加熱保温できると共に、食品の加熱殺菌も充分に行うことができ、また加熱作業時における火傷等の危険もなく、しかも、何度でも繰り返し使用ができて経済性にも優れた電磁誘導加熱式の食品加熱保温容器を提供することにある。   The present invention has been made in view of the problems as described above, and the object of the present invention is to heat and keep only foods contained in arbitrarily selected containers and to sufficiently sterilize foods. An object of the present invention is to provide an electromagnetic induction heating type food heating and insulating container that can be used, has no danger of burns during heating, and can be used over and over again and is excellent in economy.

前記外側容器1における電磁誘導発熱体3が配置された収容室11に所定量の水Wを注入して前記電磁誘導発熱体3を電磁調理器Eにより誘導加熱したとき、発熱した電磁誘導発熱体3により加熱された熱水或いは水蒸気が当該内装された内側容器2’を間接的に加熱して、外側容器1に装着された全ての内側容器2・2…の中、電磁誘導発熱体3で加熱された内側容器2’に収容された食品だけを選択的に加熱・保温可能とした点に特徴がある。
That is, the present invention is made of the non-conductive material, and the outer container 1 having a plurality of storage chambers 11, 11. A plurality of inner containers 2, 2... That are prepared and can store food F therein, and are dropped into the open space of the selected storage chamber 11 in the outer container 1; An electromagnetic induction heating element 3 arranged at the bottom of the selected storage chamber 11 in the outer container 1,
When a predetermined amount of water W is injected into the storage chamber 11 where the electromagnetic induction heating element 3 in the outer container 1 is disposed, and the electromagnetic induction heating element 3 is induction-heated by the electromagnetic cooker E, the generated electromagnetic induction heating element. The inner container 2 ′ in which the hot water or steam heated by 3 is heated indirectly, and the electromagnetic induction heating element 3 in all the inner containers 2, 2. Only the food contained in the heated inner container 2 ′ can be selectively heated and kept warm.
また本発明は、外側容器1に抜差し自在に仕切り板13を取り付けることによって複数の収容室11・11…をするという技術的手段を採用することができる。   Further, the present invention can employ a technical means that a plurality of storage chambers 11 are formed by attaching a partition plate 13 to the outer container 1 so as to be detachable.
また本発明は、外側容器1の仕切り板13によって形成される収容室11の形態に対応した形状が異なる複数の電磁誘導発熱体3・3…を備えるという技術的手段を採用することができる。   Further, the present invention can employ a technical means including a plurality of electromagnetic induction heating elements 3, 3... Having different shapes corresponding to the shape of the storage chamber 11 formed by the partition plate 13 of the outer container 1.
また本発明は、電磁誘導発熱体3に気抜き孔31・31…を設けて、発熱した電磁誘導発熱体3の下面近傍の水中から発生する気泡を前記気抜き孔31・31…から上方に逃がして電磁誘導発熱体3の浮き上がりやがたつきを防止するという技術的手段を採用することができる。   Further, according to the present invention, vent holes 31 are formed in the electromagnetic induction heating element 3 so that air bubbles generated from the water near the lower surface of the generated electromagnetic induction heating element 3 are directed upward from the vent holes 31. It is possible to adopt a technical means for escaping and preventing the electromagnetic induction heating element 3 from floating and rattling.
また本発明は、外側容器1の収容室11・11…に複数の電磁誘導発熱体3・3…を配置すると共に、これらの電磁誘導発熱体3・3…を複数の励磁コイルC・C…が内蔵された電磁調理器E或いは複数の電磁調理器E・E…によって加熱するという技術的手段を採用することができる。   In the present invention, a plurality of electromagnetic induction heating elements 3, 3... Are arranged in the accommodating chambers 11, 11... Of the outer container 1, and the electromagnetic induction heating elements 3. It is possible to adopt a technical means of heating by an electromagnetic cooker E with a built-in or a plurality of electromagnetic cookers EE ....
また本発明は、外側容器1における電磁誘導発熱体3を配置しない収容室11に蓄冷材4を配置して非加熱食品Qが収容された内側容器2を保冷できるようにするという技術的手段を採用することができる。   The present invention also provides a technical means for arranging the cold storage material 4 in the storage chamber 11 where the electromagnetic induction heating element 3 in the outer container 1 is not arranged so that the inner container 2 containing the non-heated food Q can be kept cold. Can be adopted.
本発明では、外側容器に形成した収容室の開空部に内側容器を装着すると共に、外側容器の複数の収容室の内、加熱食品が入った内側容器を挿入する収容室には、予め電磁誘導発熱体を配置して水を注入しておくことにより、喫食する前に外側容器を電磁調理器にかけて電磁誘導発熱体を水中で加熱させれば、発熱した電磁誘導発熱体によって加熱された熱水或いは水蒸気で加熱食品が入った内側容器を間接的に温めることが可能となる。   In the present invention, the inner container is attached to the open portion of the accommodation chamber formed in the outer container, and the accommodation chamber into which the inner container containing the heated food is inserted among the plurality of accommodation chambers of the outer container is electromagnetically installed in advance. By placing the induction heating element and injecting water, if the electromagnetic induction heating element is heated in water by placing the outer container on an electromagnetic cooker before eating, the heat heated by the generated electromagnetic induction heating element It becomes possible to indirectly warm the inner container containing the heated food with water or steam.
そしてこれにより、煮物や揚げ物などの加熱食品と冷菜やデザートなどの非加熱食品とを同じ弁当容器内に収容しつつ、加熱食品のみを簡単に温めることが可能となるため、加熱食品については温かい状態で、かつ、非加熱食品については冷たい状態のままで美味しく喫食することができる。   And this makes it possible to easily heat only heated food while containing heated food such as boiled food and fried food and non-heated food such as cold vegetables and dessert in the same lunch container. In a warm state, non-heated food can be eaten deliciously in a cold state.
なお、電磁調理器による電磁誘導発熱体の誘導加熱を停止した後も、水蒸気及び熱水の放熱によって一定時間、加熱食品の温度を保つことができるため、食品の加熱から喫食までに多少時間が空いても温かい状態を保つことができる。   In addition, even after the induction heating of the electromagnetic induction heating element by the electromagnetic cooker is stopped, the temperature of the heated food can be maintained for a certain period of time by the heat radiation of steam and hot water. Even if it is free, it can keep warm.
また、上記の湯煎加熱法によれば、内側容器の内周面全体から食品に対して100℃近くの加熱を行うことができるため、食品の内部までしっかりと熱を通して加熱殺菌を充分に行うことも可能となる。   In addition, according to the hot water heating method described above, since the food can be heated to nearly 100 ° C. from the entire inner peripheral surface of the inner container, heat sterilization is sufficiently performed through the heat firmly to the inside of the food. Is also possible.
そしてまた、電磁誘導発熱体と水を外側容器の収容室に入れておけば、加熱時には外側容器を電磁調理器に載せて調理器を作動させるだけでよいため、加熱作業に火傷等の危険が伴うこともなく安全である。   Also, if the electromagnetic induction heating element and water are placed in the storage chamber of the outer container, it is only necessary to place the outer container on the electromagnetic cooker and operate the cooker during heating. Safe without accompanying.
他方また、電磁誘導発熱体に使用回数の制限はなく何度でも繰り返して使用することができるため、本発明品を大量の弁当を扱う病院食や学校給食などの調理現場で使用した場合であっても経済面で問題は生じることはない。   On the other hand, the electromagnetic induction heating element is not limited in the number of times of use, and can be used repeatedly as many times as necessary, so that the product of the present invention is used in a cooking place such as hospital food or school lunch that handles a large amount of lunch. But there will be no economic problems.
したがって、本発明により、容器に収容した食品を選択的に加熱保温することが可能となるだけでなく、使用上での安全性や経済性、そして食品衛生面についても改善が図れる実用性に優れた食品容器を提供できることから、本発明の実用的利用価値は頗る高い。   Therefore, according to the present invention, not only can the food contained in the container be selectively heated and kept warm, but also has excellent practicality that can be improved in terms of safety and economy in use and food hygiene. Since the food container can be provided, the practical utility value of the present invention is very high.

『実施例1』
本発明の実施例1を、図1から図7に基いて以下に説明する。ちなみに同図において、符号1で指示するものは、外側容器であり、符号2で指示するものは、内側容器である。また、符号3で指示するものは、電磁誘導発熱体であり、符号4で指示するものは、蓄冷材である。
Example 1
A first embodiment of the present invention will be described below with reference to FIGS. Incidentally, in the same figure, what is indicated by reference numeral 1 is an outer container, and what is indicated by reference numeral 2 is an inner container. Moreover, what is indicated by reference numeral 3 is an electromagnetic induction heating element, and what is indicated by reference numeral 4 is a cold storage material.
次に、実施例1の構成を以下から説明する。まず実施例1では、非導電性の材料である木材を使用して、各室内空間が断熱状態に隔てられた複数の収容室11・11を有する外側容器1を作製している(図1、図2参照)。   Next, the configuration of the first embodiment will be described below. First, in Example 1, the outer container 1 having a plurality of storage chambers 11 and 11 in which the indoor spaces are separated from each other by heat insulation is produced using wood, which is a non-conductive material (FIG. 1, FIG. 1). (See FIG. 2).
なお実施例1においては、外側容器1内に複数の収容室11・11…を形成するために、適宜な厚さの木板材を用いて作製した仕切り板13を、外側容器1の内壁に設けたガイド溝12に抜差し自在に装着して前記収容室11・11を作出している(図3参照)。   In Example 1, in order to form a plurality of storage chambers 11, 11... In the outer container 1, a partition plate 13 made of wood board material having an appropriate thickness is provided on the inner wall of the outer container 1. The accommodating chambers 11 and 11 are created by being detachably mounted in the guide groove 12 (see FIG. 3).
また、外側容器1に仕切り板13を入れた後は、複数の窓孔14a・14a…を備える上板14を段縁部15に載置して各収容室11・11に開空部を開口させている。   Moreover, after putting the partition plate 13 in the outer container 1, the upper plate 14 having a plurality of window holes 14a, 14a,... I am letting.
そして、このように形成した外側容器1の各収容室11・11の開空部には、非導電性材料である合成樹脂材料(本実施例では、「ポリプロピレン(PP)」)から作製され、内部に加熱食品P或いは非加熱食品Qが収容された複数の内側容器2・2…を落し込んでテーパ周面21で嵌装させている(図4参照)。   And in the open part of each storage chamber 11 and 11 of the outer container 1 formed in this way, it is made from a synthetic resin material (in this example, “polypropylene (PP)”) which is a non-conductive material, A plurality of inner containers 2, 2... In which the heated food P or the non-heated food Q is accommodated are dropped and fitted on the tapered peripheral surface 21 (see FIG. 4).
なお、内側容器2或いは外側容器1を合成樹脂材料から作製する場合には、耐熱温度が100℃よりも大きい材料を選択する必要があり、できれば耐熱温度が140℃以上の材料を選択するのが望ましい。   In addition, when producing the inner container 2 or the outer container 1 from a synthetic resin material, it is necessary to select a material having a heat resistant temperature higher than 100 ° C. If possible, a material having a heat resistant temperature of 140 ° C. or higher should be selected. desirable.
また上記の内側容器2を嵌装する際、加熱食品Pを収容した内側容器2’に、食品を密閉するためのフィルム蓋22がヒートシールされている場合には、熱膨張による破裂を防止するためにフィルム蓋22を剥がして封を開けておくものとする。   Further, when the inner container 2 is fitted, when the film lid 22 for sealing the food is heat-sealed in the inner container 2 ′ containing the heated food P, the burst due to thermal expansion is prevented. Therefore, the film lid 22 is peeled off and the seal is opened.
また、加熱食品Pが収容された内側容器2’を装着する外側容器1の収容室11には、導電性を有し、かつ、電気抵抗が比較的大きい鉄材料から成る電磁誘導発熱体3を予め配置し、更にその収容室11内には所定量の水を注入しておく。   In addition, an electromagnetic induction heating element 3 made of an iron material having conductivity and a relatively large electric resistance is provided in the storage chamber 11 of the outer container 1 in which the inner container 2 ′ in which the heated food P is stored is mounted. Arranged in advance, and a predetermined amount of water is poured into the storage chamber 11.
これにより、喫食する前に外側容器1を電磁調理器Eにかけて電磁誘導発熱体3を水中で誘導加熱させれば、電磁誘導発熱体3によって加熱された水Wが高温の熱水や水蒸気となって加熱食品Pを収容した内側容器2’を間接的に加熱することとなるため、加熱食品Pのみを温めることが可能になる(図5参照)。   Thereby, if the electromagnetic induction heating element 3 is induction-heated in water by applying the outer container 1 to the electromagnetic cooker E before eating, the water W heated by the electromagnetic induction heating element 3 becomes hot hot water or steam. Since the inner container 2 ′ containing the heated food P is indirectly heated, only the heated food P can be heated (see FIG. 5).
なお、上記加熱時においては、電磁誘導発熱体3の気抜き孔31・31…により、発熱した電磁誘導発熱体3の下面近傍の水中から発生する気泡を上方に逃がすことができるため、電磁誘導発熱体3の浮き上がりやがたつきが生じることはない。   During the heating, air bubbles generated from the water in the vicinity of the lower surface of the electromagnetic induction heating element 3 can be released upward by the vent holes 31, 31... Of the electromagnetic induction heating element 3. The heating element 3 is not lifted or rattled.
また、電磁調理器Eによる電磁誘導発熱体3の誘導加熱を停止した後は、図6(a)及び(b)に示すように外側容器1の上部に蓋体16を装着しておけば、水蒸気及び熱水の放熱により一定時間、温めた加熱食品Pを保温しておくことができる。   Further, after the induction heating of the electromagnetic induction heating element 3 by the electromagnetic cooker E is stopped, as shown in FIGS. 6 (a) and 6 (b), if the lid 16 is attached to the upper part of the outer container 1, The heated food P that has been warmed can be kept warm for a certain period of time by the heat radiation of water vapor and hot water.
そしてまた、加熱食品Pに対しては、熱水や水蒸気により加熱した内側容器2’の内周面から100℃近くの加熱処理を行うことが可能であるため、食品の内部までしっかりと熱を通して充分な加熱殺菌を行うこともできる。   In addition, the heated food P can be subjected to a heat treatment near 100 ° C. from the inner peripheral surface of the inner container 2 ′ heated with hot water or water vapor, so that the heat is firmly passed to the inside of the food. Sufficient heat sterilization can also be performed.
他方また、上記加熱時には外側容器1を電磁調理器Eに載せて調理器を作動させるだけでよいため、火傷等の危険はなく、また、電磁誘導発熱体3に使用回数についても制限がないため、何度でも繰り返し使用できる。   On the other hand, since it is only necessary to place the outer container 1 on the electromagnetic cooker E and operate the cooker during the heating, there is no danger of burns and the electromagnetic induction heating element 3 has no limit on the number of uses. Can be used over and over again.
一方、外側容器1の収容室11に関しては、図7に示すように仕切り板13の数を増やして他のガイド溝12にも装着することによって収容室11の数や形態を変更することができるため、収容室11の形態に対応した形状の異なる複数の電磁誘導発熱体3・3…を準備しておく。   On the other hand, with respect to the storage chamber 11 of the outer container 1, the number and form of the storage chambers 11 can be changed by increasing the number of partition plates 13 and attaching them to other guide grooves 12 as shown in FIG. 7. Therefore, a plurality of electromagnetic induction heating elements 3, 3... Having different shapes corresponding to the shape of the storage chamber 11 are prepared.
また同図に示すように、外側容器1における非加熱食品Qが収容された内側容器2を挿入する電磁誘導発熱体3が配置されない収容室11に蓄冷材4を配置すれば、非加熱食品Qを保冷することもできる。   Moreover, as shown in the figure, if the cold storage material 4 is disposed in the storage chamber 11 in which the electromagnetic induction heating element 3 for inserting the inner container 2 in which the unheated food Q is stored in the outer container 1 is disposed, the unheated food Q Can be kept cold.
ちなみに、励磁コイルCが一つだけ内蔵された電磁調理器Eに対して複数の電磁誘導発熱体3・3を配置しても電磁誘導発熱体3が適当に発熱しないことが実際に確認されているため、励磁コイルCを一つ内蔵する一般的な電磁調理器Eを使用する場合には、使用する電磁誘導発熱体3の数を一枚に抑える必要がある。   Incidentally, it is actually confirmed that even if a plurality of electromagnetic induction heating elements 3 and 3 are arranged for an electromagnetic cooker E having only one excitation coil C, the electromagnetic induction heating element 3 does not generate heat appropriately. Therefore, when using a general electromagnetic cooker E with one built-in exciting coil C, it is necessary to reduce the number of electromagnetic induction heating elements 3 to be used to one.
『実施例2』
本発明の実施例2を、図8から図10に基いて以下に説明する。実施例2では、外側容器1に合計9つ(縦横3×3)の窓孔14a・14a…が配置された上板14を使用して収容室11の開空部を設けている(図8参照)。
“Example 2”
A second embodiment of the present invention will be described below with reference to FIGS. In Example 2, the open portion of the storage chamber 11 is provided using the upper plate 14 in which a total of nine (3 × 3 in the vertical and horizontal) window holes 14a, 14a. reference).
そして、外側容器1の内部には、L型の仕切り板13・13…をガイド溝14・14…に沿って四隅に差し込んだ後、それによって形成された十字状の収容室11に同じく十字状の電磁誘導発熱体3を配置して構成している(図9参照)。   In the outer container 1, L-shaped partition plates 13, 13... Are inserted into the four corners along the guide grooves 14, 14. The electromagnetic induction heating element 3 is arranged (see FIG. 9).
これにより、外側容器1の9つの開空部における中心とその上下左右には加熱食品Pが収容された内側容器2’を装着することができ、また4隅の開空部には非加熱食品Qが収容された内側容器2を装着することができる。   As a result, the inner container 2 ′ containing the heated food P can be attached to the center of the nine open portions of the outer container 1, its upper, lower, left, and right sides, and the non-heated food is opened in the four corner open portions. The inner container 2 in which Q is accommodated can be attached.

近年では、食事を作る時間が確保できない共働きの家庭が増えたことにより既に調理された弁当や惣菜などを買って家で食べる消費者が増えており、そのような消費者からは食品の風味が落ち易い電子レンジ以外の方法で美味しく簡単に弁当等を温められる方法が望まれている。また、学校給食や病院食の調理現場では、合理化によるコスト削減が求められる一方で調理場には多くの人件費が必要となるために、結果的に低価格の品質の落ちる食材を仕入れざるをえない状況が続いている。   In recent years, an increasing number of double-income families who cannot secure time to prepare meals has increased the number of consumers who have already eaten cooked lunches and prepared dishes and eat them at home. There is a demand for a method that can easily and easily warm a bento or the like by a method other than a microwave oven that is easily dropped. In addition, school lunches and hospital food cooking sites require cost reductions through rationalization, while the kitchens require a lot of labor costs. The situation is impossible.
そのような中で、本発明の電磁誘導加熱式の食品加熱保温容器は、一般家庭において弁当内の加熱食品を適度な温度に簡単に加熱保温することが可能となるだけでなく、加熱殺菌等の衛生面の効果にも優れているため、工場等で製造した調理食品を学校給食や病院食等の弁当に利用することも容易となり、それによって人件費を削減して食材の品質向上を図ることができる有用な技術であることから、市場における需要は大きく、その産業上の利用価値は非常に高い。   Under such circumstances, the electromagnetic induction heating type food heating and holding container of the present invention can not only easily heat and heat the heated food in the lunch box to an appropriate temperature in general households, but also heat sterilization and the like. Because of its excellent hygiene effect, it is easy to use cooked foods manufactured in factories for school lunches and hospital lunches, thereby reducing labor costs and improving food quality. Because it is a useful technology that can be used, the demand in the market is great and its industrial utility value is very high.
