Description

本発明は、マイクロ波加熱調理容器に関するものである。   The present invention relates to a microwave heating cooking container.

調理のときガスコンロやIHヒーターを使うと火災ややけどの危険があるほか、調理のそばについていなければならず時間を有効に使えず不便である。   If you use a gas stove or IH heater when cooking, there is a risk of fire and burns, and you have to be near the cooking, which is inconvenient because you cannot use your time effectively.

そこで調理に電子レンジなどのマイクロ波加熱が利用し、電子レンジを利用して単に食品を温めるのではなく、炊飯を行うものとして、米及び水を収納する容器と、中央に孔を形成した中蓋と、容器と中蓋を上方から塞ぐ蓋体を備えた電子レンジ用調理器が知られている(例えば特許文献1)。   Therefore, microwave heating such as a microwave oven is used for cooking, and a container for storing rice and water and a hole in the center are formed for cooking rice rather than simply heating food using a microwave oven. There is known a cooking device for a microwave oven that includes a lid and a lid that closes the container and the inner lid from above (for example, Patent Document 1).

しかしながら、前記従来技術では以下のような理由から調理がうまくできないという問題がある。   However, the prior art has a problem that cooking cannot be performed successfully for the following reasons.

一重の調理容器に入った食材を加熱したとき、柔らかくしたり、味をしみこませたり、おいしく食べられるように十分加熱すると、加熱しすぎて水分がなくなり料理が固く不味くなってしまうおそれがある。また、加熱のしすぎを防ぐため電子レンジのタイマーで加熱時間を調整しても、生煮えとなるおそれがあり、何度も加熱を繰り返さなければならない。さらに、沸騰するまで加熱し、余熱で調理しようとしても、急激に温度が下がるので、これも内容物が生煮えとなるおそれがある。   When the ingredients in a single cooking container are heated, if they are softened, soaked in taste, or heated enough to be eaten deliciously, there is a risk that the food will be overheated and the moisture will disappear and the dish will become hard and tasteless. Moreover, even if the heating time is adjusted with a microwave timer in order to prevent overheating, there is a possibility that it will be boiled, and heating must be repeated many times. Furthermore, even if it is heated until boiling and cooking is attempted with residual heat, the temperature drops rapidly, and this may also cause the contents to be boiled.

これら問題に対応するため電子レンジの高周波出力を下げて、水分の蒸発を防ぎながらじっくりと加熱する方法もあるが、調理の完了に時間がかかるうえ、電子レンジを動作させ続けるため電気代が多くかかってしまう。   To cope with these problems, there is a method to reduce the high-frequency output of the microwave oven and slowly heat it while preventing the evaporation of moisture, but it takes time to complete cooking, and a lot of electricity costs are required to keep the microwave oven running. It will take.

また、米及び水を収容する容器と、この容器の開口端を塞ぐ外蓋と、容器と外蓋との間に設けられる中蓋を設け、容器は内容器と外容器間に保温用空間を形成した電子レンジ用調理器が知られている(例えば特許文献2)。
実開平4-36921号公報 実開平2-18322号公報
In addition, a container for storing rice and water, an outer lid for closing the open end of the container, and an inner lid provided between the container and the outer lid are provided, and the container has a space for heat insulation between the inner container and the outer container. A formed microwave cooker is known (for example, Patent Document 2).
Japanese Utility Model Publication No. 4-36921 Japanese Utility Model Publication No. 2-18322

前記後者の従来技術における容器は空気断熱を利用しているが、空気断熱の容器は発泡スチロールを利用した断熱容器よりも性能が低いので、保温調理がうまくできない。さらに、容器本体に直接食材を入れて加熱するため、長期にわたって使用を続けていると、食材が触れている内容器から水蒸気が透過し、断熱層内に水蒸気が浸入してしまう。そのため容器の断熱効果が低下し、調理がうまくできなくなるうえ、断熱層内に浸入した水蒸気が加熱により膨張し容器が変形してしまうおそれがある。   Although the container in the latter prior art uses air insulation, the air insulation container has a lower performance than the insulation container using foamed polystyrene, so that the heat insulation cooking cannot be performed well. Furthermore, since the food is directly put into the container body and heated, if it is used for a long time, the water vapor permeates from the inner container touched by the food, and the water vapor enters the heat insulating layer. For this reason, the heat insulating effect of the container is lowered, cooking cannot be performed well, and water vapor that has entered the heat insulating layer may expand due to heating and the container may be deformed.

さらに、また、炊飯するときにはおねばが発生するが、一般的なガス調理器や電気調理器では火力や電力を調整したり、おねばを溜めておく複雑で手入れのしづらい構造を設けたりして、おねばのあふれを防止している。しかし、電子レンジでは加熱中の出力調整ができないうえ、電子レンジに入る大きさの容器におねばを溜めておく複雑な構造を設けることが難しいため、発生したおねばの吹きこぼれにより、容器や電子レンジ庫内を汚してしまうおそれがある。   In addition, when rice is cooked, a rice cracker is generated, but in general gas cookers and electric cookers, the heating power and power are adjusted, and a complicated and difficult-to-care structure for storing rice crackers is provided. This prevents overflowing of the begging. However, in a microwave oven, the output during heating cannot be adjusted, and it is difficult to provide a complicated structure for storing the tomb in a container that can fit in the microwave oven. There is a risk of dirtying the inside of the range.

同様に、大豆、黒豆などを砂糖、醤油等で煮しめる煮豆の調理時においても、煮汁のあふれに伴う吹きこぼれ対策を施す必要がある。   Similarly, when cooking boiled beans in which soybeans, black beans, etc. are boiled with sugar, soy sauce, etc., it is necessary to take measures against spillage due to overflow of the broth.

そこで、本発明は電子レンジなどのマイクロ波加熱を用いて、短時間でおいしい煮炊きなどの加熱調理ができ、吹きこぼれにより容器や電子レンジ庫内を汚さず手入れのしやすいマイクロ波加熱調理容器を提供することを目的とする。   Therefore, the present invention provides a microwave heating cooking container that can be cooked in a short time using microwave heating such as a microwave oven and is easy to clean without blowing the container or the microwave oven by spilling. The purpose is to do.

5cm、口径12cm〜18cm程度のようなど、その容量は0.5L〜4L程度であり、断熱容器
8内に出し入れ自在に収納される。容器2は有底であって、ポリプロピレンなどの樹脂やガラス、陶器などのマイクロ波を透過する材料からなる。
The container 2 is sized to enter a heating chamber (not shown) of a microwave oven, for example, a height of 5 cm to 1
The capacity is about 0.5 L to 4 L, such as 5 cm and the diameter of about 12 cm to 18 cm. The container 2 has a bottom and is made of a material that transmits microwaves, such as resin such as polypropylene, glass, and ceramics.

そして、容器2の開口端部には段付き部21が形成されている。この段付き部21は開口端部の外側に張り出した張り出し部21Aの縁に縦向き部21Bを立設したもので、10mmから30mm上方に伸びており、この段付き部21を断熱容器8の上開口端部81に載
せることで、断熱容器8の外の上方に出ている。
A stepped portion 21 is formed at the opening end of the container 2. This stepped portion 21 has a vertical portion 21B standing on the edge of an overhanging portion 21A that protrudes outside the opening end, and extends upward from 10 mm to 30 mm. By placing on the upper opening end portion 81, it protrudes outside the heat insulating container 8.

容器2の開口端部の段付き部21に載せて設けられる蓋3は、平面視円形であってポリプロピレンなどの樹脂やガラス、陶器などのマイクロ波を透過する材料からなり、その中央部は高く、張り出し部21Aに載置する周辺部31は低く形成されていると共に、周辺部31における蓋3の上面は外側に向けて下向きに傾斜している。また蓋3の中央部上面に設けられる摘み32は、蓋3の中央周辺をいったんくぼませて凹部32Aを形成し、その中央を蓋3上面の高さまで凸部32Bを突設して形成されている。凸部32Bと縦向き部21Bの上端とはほぼ同じ高さ位置にある。そして、蓋3の頂部3A中央にある凸部32Bと縦向き部21Bの上端、すなわち容器2の上端開口端21Cとはほぼ同じ高さ位置にある。   The lid 3 provided on the stepped portion 21 at the opening end of the container 2 is circular in plan view, and is made of a material that transmits microwaves, such as resin such as polypropylene, glass, and ceramics, and its central portion is high. The peripheral portion 31 placed on the overhanging portion 21A is formed low, and the upper surface of the lid 3 in the peripheral portion 31 is inclined downward toward the outside. Further, the knob 32 provided on the upper surface of the central portion of the lid 3 is formed by recessing the central periphery of the lid 3 to form a concave portion 32A and projecting the convex portion 32B to the height of the upper surface of the lid 3 at the center. Yes. The convex portion 32B and the upper end of the vertically oriented portion 21B are at substantially the same height. And the convex part 32B in the top part 3A center of the lid | cover 3 and the upper end of the vertical direction part 21B, ie, the upper end opening end 21C of the container 2, are in the substantially same height position.

前記断熱容器8は上下両方向に開口部を持つ円筒状であり、金属などのマイクロ波を透過しない材料の内壁4と、内壁4よりも大径で、内壁4と略同形状の金属などの外壁5からなり、内壁4と外壁5は、それぞれの上下両方向開口部にて接続して二重構造を形成している。そして、内壁4と外壁5との間の空隙は、真空加熱炉にて真空封止されるか、もしくは低熱伝導率ガスや断熱材を充填した断熱層6を形成している。   The heat insulating container 8 has a cylindrical shape having openings in both the upper and lower directions, an inner wall 4 made of a material such as metal that does not transmit microwaves, and an outer wall made of metal having a larger diameter than the inner wall 4 and substantially the same shape as the inner wall 4. 5 and the inner wall 4 and the outer wall 5 are connected to each other in both the upper and lower direction openings to form a double structure. And the space | gap between the inner wall 4 and the outer wall 5 is vacuum-sealed with a vacuum heating furnace, or forms the heat insulation layer 6 with which low heat conductivity gas and the heat insulating material were filled.

断熱容器8の下開口部には、断熱容器8とほぼ同径の樹脂などのマイクロ波を透過する材料の底壁7が設けられている。   A bottom wall 7 made of a material that transmits microwaves, such as a resin having substantially the same diameter as that of the heat insulating container 8, is provided in the lower opening of the heat insulating container 8.

断熱容器8の表面、すなわち内壁4の内周面と外壁5の外周面には、樹脂塗料などのマイクロ波を透過する被膜のマイクロ波透過層41,51でコーティングされていてもよい。さらに、断熱容器8の上下両開口端部は、樹脂などのマイクロ波を透過する外周部材52A、52Bが、外壁5よりも大径のリング状に形成され、断熱容器8の上下両開口端部の外表面に嵌合することにより、断熱容器8の端部から縦方向に5mmから30mmの範囲を
被覆していると共に、これら外周部材52A、52Bは、断熱容器8の表面、すなわち外壁5の表面よりも数mm出ている。そして、外周部材52Bは下側の湾曲部53に嵌合して
おり、その下端には底壁7が一体となって連設している。この底壁7により断熱容器8を電子レンジのテーブル(図示せず)に置いたときに、断熱容器8の下端はテーブルから数mm離れるようになっている。
The surface of the heat insulating container 8, that is, the inner peripheral surface of the inner wall 4 and the outer peripheral surface of the outer wall 5 may be coated with microwave transmitting layers 41 and 51, such as resin coatings, that transmit microwaves. Further, both the upper and lower opening ends of the heat insulating container 8 are formed by outer peripheral members 52A and 52B that transmit microwaves such as resin in a ring shape larger in diameter than the outer wall 5, and both the upper and lower opening ends of the heat insulating container 8 The outer peripheral members 52A and 52B cover the surface of the heat insulating container 8, that is, the outer wall 5, in the longitudinal direction from the end of the heat insulating container 8 by being fitted to the outer surface. It is a few millimeters above the surface. The outer peripheral member 52B is fitted to the lower curved portion 53, and the bottom wall 7 is integrally provided at the lower end thereof. When the heat insulating container 8 is placed on a table (not shown) of the microwave oven by the bottom wall 7, the lower end of the heat insulating container 8 is separated from the table by several mm.

次に前記構成についてその作用効果を説明する。炊飯時には、米(うるち米)Rと水Wを容器2に収容し、蓋3で上方を閉じる。次に容器2を断熱容器8に収容する。これに伴い、容器2の側面外側には、内壁4と外壁5に挟まれた断熱層6が配置されると共に、容器2の底に底壁7が配置される。そして断熱容器8と一緒に蓋3を備えた容器2を、底壁7をテーブル上に載置するように電子レンジの加熱庫に収納し、そしてタイマー付きスイッチを操作することで、マイクロ波を断熱容器8や蓋3に照射する。このマイクロ波の照射によって、マイクロ波は蓋3を透過して米Rと水Wを加熱する。さらには、マイクロ波はテーブル側から底壁7を透過して米Rと水Wを加熱するようになっている。この際、加熱された米Rと水Wは、周囲温度の影響を受けて温度低下するおそれがあるが、米Rと水W、ひいては容器2の外側には断熱層6が配置されているので、米Rと水Wが温度低下することなく保温調理することができる。   Next, the effect of the above configuration will be described. At the time of cooking rice, rice (Ruchi rice) R and water W are accommodated in the container 2, and the upper portion is closed with the lid 3. Next, the container 2 is accommodated in the heat insulating container 8. Accordingly, a heat insulating layer 6 sandwiched between the inner wall 4 and the outer wall 5 is disposed outside the side surface of the container 2, and a bottom wall 7 is disposed at the bottom of the container 2. Then, the container 2 having the lid 3 together with the heat insulating container 8 is stored in a microwave oven so that the bottom wall 7 is placed on the table, and the microwave is operated by operating a switch with a timer. Irradiate the heat insulating container 8 and the lid 3. By this microwave irradiation, the microwave passes through the lid 3 and heats the rice R and the water W. Further, the microwaves pass through the bottom wall 7 from the table side and heat the rice R and the water W. At this time, the heated rice R and water W may be lowered in temperature due to the influence of the ambient temperature. However, since the heat insulating layer 6 is disposed outside the rice R and the water W, and thus the outside of the container 2. The rice R and the water W can be kept warm without lowering the temperature.

さらに、摘み32の凹部32Aを除いた蓋3における頂部3Aから周辺部31にかけての蓋3の上面、すなわち前記蓋3の上面の周縁部31側と、張り出し部21Aに縦向き部21Bが連設した段部21と、平面視が円形な段部21の上端開口端21Cの内側を閉塞するように形成される仮想天面21Dとに囲まれたおねば溜り空間Aの体積Bが、容器2内の炊飯前体積、すなわち炊飯前の米Rと水Wの最大の合計体積Cの13%以上に形成されている(B>13/100×C又はB=13/100×C)。さらに、炊飯前体積、すなわち炊飯前の米Rと水Wの最大の合計体積Cが容器2の体積D、すなわち蓋2の最下端、すなわち実施例では張り出し部21Aに載置している蓋2の周辺部31から容器2の底までの体積Dの60%以下である(C<60/100×D又はC=60/100×D)。このために、容器2の内面に表示した水Wの水量目盛22のうちの上限、すなわち上限水量目盛22Aは、上述のB>13/100×C又はB=13/100×C、かつC<60/100×D又はC=60/100×Dを満たす条件に相当する箇所に設けられている。すなわち、容器2の底側から上限水量目盛22Aに至る最大の体積Cは、C<B÷13/100又はC=B÷13/100の条件を満たし、かつC<60/100×D又はC=60/100×Dを満たすように上限水量目盛22Aが設けられている。この上限水量目盛22Aは、容器2の内側に形成した突起、印刷など炊飯における上限水量を示すものであればよい。   Further, the vertical portion 21B is connected to the upper surface of the lid 3 from the top 3A to the peripheral portion 31 of the lid 3 excluding the concave portion 32A of the knob 32, that is, the peripheral edge 31 side of the upper surface of the lid 3, and the overhanging portion 21A. The volume B of the reservoir space A surrounded by the stepped portion 21 and the virtual top surface 21D formed so as to close the inside of the upper end opening end 21C of the stepped portion 21 that is circular in plan view is the container 2 It is formed in 13% or more of the maximum total volume C of rice R before cooking rice, that is, rice R and water W before cooking (B> 13/100 × C or B = 13/100 × C). Furthermore, the volume before cooking, that is, the maximum total volume C of rice R and water W before cooking is the volume D of the container 2, that is, the lowest end of the lid 2, that is, the lid 2 placed on the overhanging portion 21A in the embodiment. 60% or less of the volume D from the peripheral portion 31 to the bottom of the container 2 (C <60/100 × D or C = 60/100 × D). For this reason, the upper limit of the water volume scale 22 of the water W displayed on the inner surface of the container 2, that is, the upper limit water volume scale 22A is B> 13/100 × C or B = 13/100 × C and C < It is provided at a location corresponding to a condition satisfying 60/100 × D or C = 60/100 × D. That is, the maximum volume C from the bottom side of the container 2 to the upper limit water volume scale 22A satisfies the condition of C <B ÷ 13/100 or C = B ÷ 13/100, and C <60/100 × D or C = An upper limit water volume scale 22A is provided so as to satisfy 60/100 × D. The upper limit water amount scale 22A may be any one that indicates the upper limit water amount in rice cooking such as protrusions and printing formed inside the container 2.

前記上限水量目盛22Aは、図5のグラフに基づくものであり、図5のグラフの横軸は、炊飯前体積Cを体積Dで除したものをパーセント表示したものである(炊飯前体積C/体積D×100 %)。図5の縦軸は、おねば溜り空間Aの体積Bを炊飯前体積Cで除したものをパーセント表示したものである(おねば溜り空間Aの体積B/体積D×100 %)。そしてそれぞれの条件で炊飯しておねばの溢れ状況、すなわちおねばが上端開口端21より溢れ出てしまうか、否かを実験したものである。この実験結果、おねば溜り空間Aの体積B/体積D×100%が、13%以上では溢れはなく、13%より低くなると溢れが生ずることが判明した。さらに、炊飯前体積C/体積D×100%においては、60%以下では溢れはなく、60%を超えると溢れが生ずることが判明した。   The upper limit water volume scale 22A is based on the graph of FIG. 5, and the horizontal axis of the graph of FIG. 5 is a percentage of the volume C before cooking rice divided by the volume D (volume C / before cooking rice). Volume D × 100%). The vertical axis | shaft of FIG. 5 displays what divided the volume B of the rice pool space A by the volume C before cooking rice as a percentage (volume B of the rice pool space A / volume Dx100%). An experiment was conducted to determine whether the rice overflows when the rice is cooked under each condition, that is, whether the rice overflows from the upper end opening end 21. As a result of this experiment, it was found that when the volume B / volume D × 100% of the reservoir space A is 13% or more, there is no overflow, and when it is lower than 13%, overflow occurs. Furthermore, in the volume C before cooking rice / volume D × 100%, it was found that there is no overflow at 60% or less, and overflow occurs when it exceeds 60%.

以上のように、マイクロ波透過性材料からなる調理用容器2と、この調理用容器2の上部開口に設けられる蓋3と、前記調理用容器2の側面外側に配置され内壁4と外壁5との間に断熱層6を設けた断熱容器8を備えたことにより、断熱容器8に直接食材を入れるのではなく容器2に入れるので、水蒸気等が断熱層内に浸入せず、また、断熱容器8内の容器2が出し入れ自在であることにより、洗浄などの際に容器2と断熱容器8をそれぞれ単独で取り扱うことができるようになる。さらに、前記容器2の開口端に外側に張り出した張り出し部21Aの外側に縦向き部21Bを立設した段部21が設けられ、該段部21に前記蓋3が載置されたことにより、鍋の開口部は蓋を載せるための段付き構造を有し、容器2の上端開口端21Cが蓋2を載せる面、すなわち張り出し部21Aよりも上に長く伸びており、炊飯においては米から大量のおねばが発生しても、おねばは容器2の蓋3の下の空間のみならず、容器2の上端開口端21Cと蓋3の間の空間、すなわちおねば溜り空間Aに溜まるようになり、おねばが容器2より溢れ出て電子レンジの加熱庫内をおねばで汚すようなことはない。同様に、容器2に大豆、黒豆など豆類を砂糖、醤油等で煮しめる煮豆を加熱調理する場合、煮汁が容器2の蓋3の下の空間のみならず、容器2の上端開口端21Cと蓋3の間の空間、すなわち煮汁溜り空間Aに溜まるようになり、煮汁が容器2より溢れ出て電子レンジの加熱庫内を煮汁で汚すようなことはない。   As described above, the cooking container 2 made of a microwave permeable material, the lid 3 provided in the upper opening of the cooking container 2, the inner wall 4 and the outer wall 5 disposed outside the side surface of the cooking container 2, By providing the heat insulating container 8 provided with the heat insulating layer 6 between them, the foodstuff is not directly put into the heat insulating container 8, but is put into the container 2, so that water vapor or the like does not enter the heat insulating layer, and the heat insulating container Since the container 2 in the container 8 can be taken in and out, the container 2 and the heat insulating container 8 can be handled independently during cleaning. In addition, a stepped portion 21 having a vertically extending portion 21B is provided on the outer side of a protruding portion 21A protruding outward at the opening end of the container 2, and the lid 3 is placed on the stepped portion 21. The opening of the pan has a stepped structure for placing a lid, and the upper end opening end 21C of the container 2 extends longer than the surface on which the lid 2 is placed, that is, the overhanging portion 21A. Even if a beep occurs, the bean accumulates not only in the space under the lid 3 of the container 2 but also in the space between the upper end opening end 21C of the container 2 and the lid 3, that is, in the beard accumulation space A. Thus, the rice cake will not overflow from the container 2 and the inside of the heating chamber of the microwave oven will be soiled with the rice cake. Similarly, when cooking boiled beans in which beans such as soybeans and black beans are boiled in sugar, soy sauce, etc. in the container 2, the soup is not only the space under the lid 3 of the container 2 but also the upper end opening end 21 </ b> C of the container 2 and the lid 3, i.e., the boiled juice storage space A, and the boiled juice does not overflow from the container 2 and does not contaminate the heating chamber of the microwave oven with the boiled juice.

また、蓋3における頂部3Aから周辺部31にかけての蓋3の上面と、張り出し部21Aに縦向き部21Bが連設した段部21と、平面視が円形な段部21の上端開口端21Cの内側を閉塞するように形成される仮想天面21Dとに囲まれたおねば溜り空間Aの体積Bが、容器2内の炊飯体積、すなわち炊飯前の米Rと水Wの合計前体積Cの13%以上に形成されていることで、炊飯時のおねばの上端開口端21Cからの吹きこぼれを防止することができる。   Further, an upper surface of the lid 3 from the top 3A to the peripheral portion 31 of the lid 3, a stepped portion 21 in which a vertically oriented portion 21B is connected to the projecting portion 21A, and an upper end opening end 21C of the stepped portion 21 having a circular plan view. The volume B of the rice paddy space A surrounded by the virtual top surface 21D formed so as to close the inside is the rice cooking volume in the container 2, that is, the total volume C before the rice R and water W before cooking. By being formed at 13% or more, it is possible to prevent spillage from the upper end opening end 21C of the rice bowl during cooking.

さらに、炊飯体積、すなわち炊飯前の米Rと水Wの合計前体積Cが容器2の体積D、すなわち張り出し部21Aから容器2の底までの体積Dの60%以下にすることで、炊飯時のおねばの上端開口端21Cからの吹きこぼれを防止することができる。   Furthermore, the rice cooking volume, that is, the total volume C before the rice R and the water W before cooking rice is set to 60% or less of the volume D of the container 2, that is, the volume D from the overhanging portion 21A to the bottom of the container 2 It is possible to prevent spillage from the upper end opening end 21C of the rice bowl.

以下に、他の実施例について説明する。尚、前記実施例1と同一部分には同一符号を付し、その詳細な説明を省略する。図は実施例2を示しており、前記実施例1と同一部分には同一符号を付し、その詳細な説明を省略する。   Other embodiments will be described below. In addition, the same code | symbol is attached | subjected to the same part as the said Example 1, and the detailed description is abbreviate | omitted. The figure shows a second embodiment, and the same parts as those of the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

図3に示す実施例2における蓋3は隙間を隔てて配置された樹脂やガラス、陶器などのマイクロ波を透過する材料の内蓋33と、内蓋33とほぼ同径の外蓋34から構成されている。   The lid 3 in the second embodiment shown in FIG. 3 includes an inner lid 33 made of a material that transmits microwaves, such as resin, glass, and ceramics, and an outer lid 34 having substantially the same diameter as the inner lid 33. Has been.

以上のように、前記蓋3は、隙間を隔てて配置された内蓋33と外蓋34からなるので、蓋3が二重構造となり断熱効果を高めることができる。そして蓋3の外蓋34における頂部3Aから外側に向けて下向きとなる周辺部31にかけての外蓋34の上面と、張り出し部21Aに縦向き部21Bが連設した段部21と、平面視が円形な段部21の上端開口端21Cの内側を閉塞するように形成される仮想天面とに囲まれたおねば溜り空間の体積が、炊飯前体積の13%以上に形成されている。さらに、炊飯前体積を容器2の体積の60%以下である。このようにすることで、おねばの上端開口端21Cからの溢れを防止することができる。   As described above, since the lid 3 is composed of the inner lid 33 and the outer lid 34 arranged with a gap therebetween, the lid 3 has a double structure and can enhance the heat insulating effect. The top surface of the outer lid 34 of the outer lid 34 of the lid 3 extending from the top 3A toward the outer side toward the outer side, the stepped portion 21 in which the vertically oriented portion 21B is connected to the projecting portion 21A, and a plan view The volume of the pocket space surrounded by the virtual top surface formed so as to close the inside of the upper end opening end 21C of the circular step portion 21 is formed to be 13% or more of the pre-rice cooking volume. Furthermore, the volume before cooking is 60% or less of the volume of the container 2. By doing in this way, the overflow from the upper end opening end 21C of the rice bowl can be prevented.

図4に示す実施例3における、蓋3は隙間を隔てて配置された樹脂やガラス、陶器などのマイクロ波を透過する材料の蓋内壁33´と、蓋内壁33´とほぼ同径で該蓋内壁33´と一体な蓋外壁34´から構成されている。尚、蓋内壁33´と蓋外壁34´との隙間に低熱伝導率ガスや断熱材を充填した断熱層33Aを有する断熱蓋であってもよい。   In the third embodiment shown in FIG. 4, the lid 3 has a lid inner wall 33 ′ made of a material that transmits microwaves, such as resin, glass, ceramics, and the like, and is substantially the same diameter as the lid inner wall 33 ′. It is comprised from the lid outer wall 34 'integral with inner wall 33'. In addition, the heat insulation lid | cover which has the heat insulation layer 33A with which low thermal conductivity gas and the heat insulating material were filled into the clearance gap between lid inner wall 33 'and lid outer wall 34' may be sufficient.

また、前記底壁7は隙間を隔てたマイクロ波透過性材料の底内壁71と底外壁72からなる。これら底内壁71と底外壁72は、隙間を隔てて縁において接続され、その隙間に低熱伝導率ガスや断熱材を充填した断熱層が形成されていてもよい。これにより下部開口部からの熱損失を低減し、調理容器2の保温効果を高めることができる。ここで、食材を断熱容器8ごと加熱する場合、低熱伝導率ガスなどの膨張により下部開口部の底内壁71と底外壁72が変形し、調理容器2を安定して置くことが出来なくなるおそれがある。そこで、下部開口部の底内壁71と底外壁72を上に凸、もしくは下に凸に形成すること、実施例では下に凸に形成することとして変形を小さくし、容器2を安定して置くことができるようになっている。   The bottom wall 7 is composed of a bottom inner wall 71 and a bottom outer wall 72 made of a microwave permeable material with a gap therebetween. The bottom inner wall 71 and the bottom outer wall 72 may be connected at an edge with a gap therebetween, and a heat insulating layer filled with a low thermal conductivity gas or a heat insulating material may be formed in the gap. Thereby, the heat loss from a lower opening part can be reduced, and the heat retention effect of the cooking vessel 2 can be improved. Here, when the food material is heated together with the heat insulating container 8, the bottom inner wall 71 and the bottom outer wall 72 of the lower opening are deformed due to expansion of the low thermal conductivity gas or the like, and the cooking container 2 may not be stably placed. is there. Therefore, the bottom inner wall 71 and the bottom outer wall 72 of the lower opening are formed so as to protrude upward or downward, and in the embodiment, they are formed downward so that the deformation is reduced and the container 2 is stably placed. Be able to.

そして蓋3の外蓋34´における頂部3Aから周辺部31にかけての外蓋34´の上面と、張り出し部21Aに縦向き部21Bが連設した段部21と、平面視が円形な段部21の上端開口端21Cの内側を閉塞するように形成される仮想天面21Dとに囲まれたおねば溜り空間Aの体積Bが、容器2内の炊飯前体積C、すなわち炊飯前の米と水の合計体積の13%以上に形成されている。さらに、炊飯前体積Cは容器2の体積Dの60%以下である。この場合、炊飯体積Dは蓋2の最下端、すなわち実施例では蓋内壁33´の下面から容器2の底までの体積となる。このようにすることで、おねばの上端開口端21Cからの溢れを防止することができる。   Then, the upper surface of the outer lid 34 ′ from the top 3 A to the peripheral portion 31 of the outer lid 34 ′ of the lid 3, the stepped portion 21 in which the vertically-oriented portion 21 B is connected to the protruding portion 21 A, and the stepped portion 21 having a circular plan view. The volume B of the rice paddy space A surrounded by the virtual top surface 21D formed so as to close the inside of the upper end opening end 21C is the volume C before cooking in the container 2, that is, the rice and water before cooking. It is formed in 13% or more of the total volume. Furthermore, the volume C before cooking is 60% or less of the volume D of the container 2. In this case, the rice cooking volume D is the lowest end of the lid 2, that is, the volume from the lower surface of the lid inner wall 33 'to the bottom of the container 2 in the embodiment. By doing in this way, the overflow from the upper end opening end 21C of the rice bowl can be prevented.

以上のように本発明に係るマイクロ波加熱調理器は、炊飯や煮豆などのほかにも各種の用途に適用できる。   As described above, the microwave heating cooker according to the present invention can be applied to various uses in addition to cooked rice and boiled beans.
