本発明は、マイクロ波とヒータとを用いて食品を加熱するオーブン機能を有する電子レンジなどの加熱調理器に関するものである。 The present invention relates to a cooking device such as a microwave oven having an oven function for heating food using a microwave and a heater.
従来、この種の加熱調理器における加熱方法としては、被加熱物に対して上面から加熱する上面加熱手段、および、下面から加熱する下面加熱手段を同時または別々に用いて加熱を行い、上面加熱手段に関しては加熱領域を限定して加熱するものがある（例えば、特許文献１参照）。 Conventionally, as a heating method in this type of heating cooker, heating is performed by simultaneously or separately using an upper surface heating means for heating an object to be heated from the upper surface and a lower surface heating means for heating from the lower surface. Regarding the means, there is one that heats by limiting the heating region (see, for example, Patent Document 1).
この方法では、マイクロ波加熱によって食品内部から加熱を行い、上面加熱手段からの輻射熱と被加熱物の載置皿からの発熱とにより調理を行う。 In this method, heating is performed from the inside of the food by microwave heating, and cooking is performed by radiant heat from the upper surface heating means and heat generated from the placing plate of the object to be heated.
この加熱方法による利点として、調理時間の短縮と複数食材の同時調理や調理時間短縮が挙げられる。 Advantages of this heating method include shortening the cooking time, simultaneous cooking of multiple ingredients, and shortening the cooking time.
しかしながら、前記従来の構成では、上面加熱手段による加熱領域の限定は行われていたが、下面加熱手段による加熱領域の限定および上面加熱手段と下面加熱手段による同時集中加熱は行われていなかった。 However, in the conventional configuration, the heating region is limited by the upper surface heating unit, but the heating region is not limited by the lower surface heating unit and the simultaneous central heating by the upper surface heating unit and the lower surface heating unit is not performed.
そのため、下面加熱手段による加熱では加熱室内全体を加熱することとなり、上下面からの同時集中加熱と比較して、被加熱物に与えられる熱量が減少し、調理時間の増加および消費電力の浪費という課題を有していた。 Therefore, in the heating by the lower surface heating means, the entire heating chamber is heated, and compared with simultaneous concentrated heating from the upper and lower surfaces, the amount of heat given to the object to be heated is reduced, cooking time is increased and power consumption is wasted. Had problems.
本発明は、前記従来の課題を解決するものであり、その目的は従来のゾーン加熱方法で実現できていなかった上面および下面加熱手段を用いた同時集中加熱により、調理時間の短縮および消費電力の低減を実現する加熱調理器を提供することである。 The present invention solves the above-described conventional problems, and the object is to reduce cooking time and reduce power consumption by simultaneous centralized heating using upper and lower surface heating means that could not be realized by the conventional zone heating method. It is providing the cooking device which implement | achieves reduction.
本発明の加熱調理器の加熱方法は、載置皿における被加熱物の載置位置に応じた一部の加熱領域に対して、上面加熱手段およびマイクロ波加熱によって上下面から同時に加熱するものである。上面加熱手段により上面に焼き色がつけられ、マイクロ波加熱により被加熱物の内部から加熱することができる。 The heating method of the heating cooker of the present invention is to simultaneously heat the upper and lower surfaces by upper surface heating means and microwave heating to a part of the heating area corresponding to the placement position of the object to be heated on the placing plate. is there. The upper surface is colored by the upper surface heating means, and can be heated from the inside of the object to be heated by microwave heating.
特に、載置皿にはマイクロ波吸収発熱体が貼付されており、発熱体によって被加熱物の底面を高温にして被加熱物の下面にまず焼き色をつけることにより、被加熱物に含まれるうまみ成分や栄養素などが外部に漏れ出すことを防ぐものである。また被加熱物に焼き色をつけることで、被加熱物の見栄えも良くすることができる。 In particular, a microwave-absorbing heating element is affixed to the mounting plate, and is included in the object to be heated by first heating the bottom surface of the object to be heated and coloring the lower surface of the object to be heated by the heating element. It prevents umami ingredients and nutrients from leaking out. Moreover, the appearance of a to-be-heated object can also be improved by coloring the to-be-heated object.
さらに、内部と外部を同時に加熱できることから、高い効率で加熱することができる。このように、複数の加熱要素を同時に、加熱領域を絞って用いることで、調理時間の短縮
、消費電力の低減が可能となる。
Furthermore, since the inside and the outside can be heated at the same time, it can be heated with high efficiency. As described above, by simultaneously using a plurality of heating elements while narrowing the heating region, cooking time can be shortened and power consumption can be reduced.
本発明によれば、加熱室内の全体の温度上昇を待たずに被加熱物の温度を上昇させることが可能となるため、調理時間の短縮や消費電力の低減が可能となる。 According to the present invention, the temperature of the object to be heated can be raised without waiting for the whole temperature rise in the heating chamber, so that cooking time can be shortened and power consumption can be reduced.
第１の発明は、加熱室と、マイクロ波を発生するマイクロ波発生手段と、回転軸を中心に回転し前記マイクロ波を前記加熱室内に放射するアンテナと、前記アンテナの回転を駆動するアンテナ駆動部と、前記加熱室を上下に分割するように前記加熱室内に係止され被加熱物を載置するとともに裏面にマイクロ波を吸収するマイクロ波吸収発熱体が貼付された載置皿と、前記加熱室の上部に設けられ前記載置皿の上面側を加熱する上面加熱手段と、前記載置皿の一部領域を集中的に加熱するように前記マイクロ波発生手段と前記アンテナ駆動部と前記上面加熱手段とを制御する制御部とを備えたものである。 The first invention includes a heating chamber, microwave generation means for generating a microwave, an antenna that rotates about a rotation axis and radiates the microwave into the heating chamber, and an antenna drive that drives rotation of the antenna A mounting dish on which a microwave absorbing heating element that is locked in the heating chamber and absorbs microwaves is attached to the back surface, An upper surface heating means that is provided in the upper part of the heating chamber and heats the upper surface side of the placing plate, the microwave generating means, the antenna driving unit, and the And a controller for controlling the upper surface heating means.
本発明によれば、加熱室内の全体の温度上昇を待たずに被加熱物の温度を上昇させることが可能となるため、調理時間の短縮や消費電力の低減が可能となる。 According to the present invention, the temperature of the object to be heated can be raised without waiting for the whole temperature rise in the heating chamber, so that cooking time can be shortened and power consumption can be reduced.
第２の発明は、特に第１の発明において、前記制御部が、前記載置皿の一部領域の裏面に対して、前記載置皿の一部領域以外の裏面より前記マイクロ波を多く供給するように前記アンテナ駆動部を制御する下方加熱制御部を有するものである。 In a second aspect of the invention, particularly in the first aspect of the invention, the control unit supplies more microwaves to the back surface of the partial area of the mounting plate than from the back surface other than the partial area of the mounting plate. Thus, a lower heating control unit for controlling the antenna driving unit is provided.
本発明によれば、被加熱物が載置される載置皿の領域の裏面に対して、集中してマイクロ波を供給することにより、調理時間の短縮や消費電力の低減を図ることができる。 According to the present invention, cooking time can be shortened and power consumption can be reduced by concentrating and supplying microwaves to the back surface of the area of the placing tray on which the object to be heated is placed. .
また、アンテナ制御により被加熱物の載置部分に対して集中して加熱を行えることから、必要な部分の加熱だけを行うことができ、消費電力の低減が実現することができる。 In addition, since the heating can be concentrated on the placement portion of the object to be heated by the antenna control, only the necessary portion can be heated, and the power consumption can be reduced.
第３の発明は、特に第１の発明において、前記制御部が、前記載置皿の一部領域の上面に対して、前記載置皿の前記一部領域以外の上面より前記上面加熱手段からの輻射熱が多く供給されるよう前記上面加熱手段を制御する上方加熱制御部を有するものである。 According to a third aspect of the present invention, in the first aspect of the invention, the control unit may be configured so that the upper surface heating unit is configured to apply the upper surface to the upper surface of the partial area of the mounting plate from the upper surface other than the partial area of the mounting plate. An upper heating control unit for controlling the upper surface heating means so that a large amount of radiant heat is supplied.
本発明によれば、被加熱物が載置されていない載置皿の領域に関しては、上方から輻射熱を停止することにより、調理時間の短縮や消費電力の低減を図ることができる。 According to the present invention, the cooking time and power consumption can be reduced by stopping the radiant heat from above for the area of the placing tray on which the object to be heated is not placed.
以下、本発明の実施の形態について、図面を参照しながら説明する。なお、本実施の形態によって本発明が限定されるものではない。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the present embodiment.
（実施の形態）
図１は、本発明の実施の形態における加熱調理器１の外観斜視図である。加熱調理器１には外郭の一部を構成し、加熱室２に対して前方に開くことのできる扉３が取り付けられている。
(Embodiment)
FIG. 1 is an external perspective view of a cooking device 1 according to an embodiment of the present invention. A door 3 that constitutes a part of the outer shell and can be opened forward with respect to the heating chamber 2 is attached to the heating cooker 1.
扉３には、取っ手４、加熱条件や被加熱物２６の情報を入力する操作ボタン５、そして入力した内容や調理経過状況、被加熱物情報が表示される表示部６が取り付けられている。 The door 3 is provided with a handle 4, an operation button 5 for inputting information on the heating condition and the object to be heated 26, and a display unit 6 for displaying the input content, cooking progress, and information on the object to be heated.
図２は、加熱調理器１の加熱室２の内部を側面から観た概略図である。被加熱物２６を上面から加熱する第１の加熱手段として、シーズヒータ等からなる管ヒータ１４ａ、１４ｂ、１４ｃが加熱室２の上部に取り付けられ、載置皿１９上の被加熱物２６を上面から輻射加熱する。上方加熱制御部２４は、管ヒータ１４ａ、１４ｂ、１４ｃに供給する電力を制御する。 FIG. 2 is a schematic view of the inside of the heating chamber 2 of the heating cooker 1 as viewed from the side. As first heating means for heating the object to be heated 26 from the upper surface, tube heaters 14a, 14b, 14c made of sheathed heaters and the like are attached to the upper part of the heating chamber 2, and the object 26 to be heated on the mounting plate 19 is moved to the upper surface. Heat from radiant. The upper heating control unit 24 controls the power supplied to the tube heaters 14a, 14b, and 14c.
加熱室２の下方には、被加熱物２６を下面から加熱する第２の加熱手段であるマイクロ波発生手段であるマグネトロン２３が設けられ、マグネトロン２３が発生したマイクロ波をマイクロ波攪拌手段であるアンテナ１３により加熱室２内に攪拌させる。 Below the heating chamber 2, a magnetron 23, which is a microwave generating means, which is a second heating means for heating the object 26 from the lower surface, is provided, and the microwave generated by the magnetron 23 is a microwave stirring means. The heating chamber 2 is agitated by the antenna 13.
アンテナ１３は、マイクロ波の出力方向に関して指向性を有するアンテナであり、アンテナ駆動部１２により回転軸１０を中心に回転運動を行うことで、通常の加熱においては、連続的に回転させ、加熱室２内の被加熱物２６を均一に加熱する。ガラスプレート９は加熱室２の底面を構成し、通常のマイクロ波加熱の際には、ガラスプレート９上に被加熱物が載置される。 The antenna 13 is an antenna having directivity in the microwave output direction, and is rotated continuously around the rotating shaft 10 by the antenna driving unit 12, so that the antenna 13 is continuously rotated in normal heating, and is heated. The object to be heated 26 in 2 is heated uniformly. The glass plate 9 constitutes the bottom surface of the heating chamber 2, and an object to be heated is placed on the glass plate 9 during normal microwave heating.
載置皿１９は、裏面にマイクロ波を吸収して発熱するマイクロ波吸収発熱体７が貼付され、加熱室２に供給されたマイクロ波を受けて発熱することで、載置皿１９に載置された被加熱物２６を下方から加熱し、マイクロ波を用いた焼き物調理を行うために用いられる。載置皿１９は、加熱室２内の係止部８ａ、８ｂ、８ｃのいずれかに係止させることにより加熱室２内に設置される。 The mounting tray 19 is mounted on the mounting tray 19 by attaching a microwave absorption heating element 7 that generates heat by absorbing microwaves on the back surface, and generates heat by receiving the microwave supplied to the heating chamber 2. The heated object to be heated 26 is heated from below and used for cooking the grilled food using microwaves. The mounting tray 19 is installed in the heating chamber 2 by being locked to any one of the locking portions 8a, 8b, 8c in the heating chamber 2.
下方加熱制御部１１は、アンテナ１３を任意の方向に向けるようアンテナ駆動部１２を制御する。例えば、アンテナ１３を加熱室２の前方、すなわち扉３に近い側に向ければ、その方向の載置皿１９の裏面にマイクロ波を集中させることができ、加熱室２の前方の載置皿１９だけを発熱させるができる。これにより、加熱室２の前方の載置皿１９上に存在する被加熱物２６を限定的に加熱することが可能となる。 The lower heating control unit 11 controls the antenna driving unit 12 to direct the antenna 13 in an arbitrary direction. For example, if the antenna 13 is directed in front of the heating chamber 2, that is, on the side close to the door 3, microwaves can be concentrated on the back surface of the mounting tray 19 in that direction, and the mounting tray 19 in front of the heating chamber 2. Can only heat up. Thereby, it becomes possible to heat the to-be-heated object 26 which exists on the mounting tray 19 ahead of the heating chamber 2 limitedly.
加熱領域を限定する際にどの領域を選択するかについては、載置皿１９の扉３に近い側に限定されず、加熱室２の奥側、すなわち扉３から遠い側や、加熱室２の左右いずれかの半分の領域などでも良い。 The region to be selected when the heating region is limited is not limited to the side near the door 3 of the mounting tray 19, but the rear side of the heating chamber 2, that is, the side far from the door 3 or the heating chamber 2. The left or right half area may be used.
また、加熱室２内に温度センサ１６が設けられ、加熱室２内の温度があらかじめ設定した温度を超えた場合、管ヒータ１４ａ〜１４ｃおよびマグネトロン２３への電力供給を抑制する。 Moreover, the temperature sensor 16 is provided in the heating chamber 2, and when the temperature in the heating chamber 2 exceeds a preset temperature, power supply to the tube heaters 14a to 14c and the magnetron 23 is suppressed.
図３（ａ）、（ｂ）は、図１における加熱室２内の加熱領域限定時の加熱方法を説明するための概念図である。図３（ａ）に示されるように、加熱領域を限定しない場合は、アンテナ１３を３６０度回転させるとともに、管ヒータ１４ａ、１４ｂ、１４ｃをすべてオンする。 3A and 3B are conceptual diagrams for explaining a heating method when the heating region in the heating chamber 2 in FIG. 1 is limited. As shown in FIG. 3A, when the heating region is not limited, the antenna 13 is rotated 360 degrees and all the tube heaters 14a, 14b, and 14c are turned on.
これにより、載置皿１９の裏面全体にマイクロ波が照射されて載置皿１９の全体（図３（ａ）に示される領域４０）が発熱するとともに、管ヒータ１４ａ、１４ｂ、１４ｃにより上方から載置皿１９の全体を輻射加熱することができる。 As a result, the entire back surface of the mounting tray 19 is irradiated with microwaves, and the entire mounting tray 19 (the region 40 shown in FIG. 3A) generates heat, and the tube heaters 14a, 14b, and 14c from above. The entire mounting tray 19 can be radiantly heated.
図２に示されるように、被加熱物２６が加熱室２の前方、すなわち載置皿１９の扉３に
近い側に載置されたときには、図３（ｂ）に示されるように、上面加熱手段における上方加熱制御部２４によって管ヒータ１４ａ、１４ｂのみをオンし、管ヒータ１４ｃはオフする。
As shown in FIG. 2, when the object to be heated 26 is placed in front of the heating chamber 2, that is, on the side close to the door 3 of the placing tray 19, as shown in FIG. Only the tube heaters 14a and 14b are turned on by the upper heating control unit 24 in the means, and the tube heater 14c is turned off.
それとともに、下方加熱制御部１１によって載置皿１９の扉３に近い側（図３（ｂ）に示される領域４１）にマイクロ波を集中させるようアンテナ１３を制御し、被加熱物２６の上面と下面から同時に被加熱物の載置位置に限定した加熱を行うことで高効率な調理と調理時間の短縮を行うことができる。 At the same time, the lower heating control unit 11 controls the antenna 13 so that the microwaves are concentrated on the side close to the door 3 of the mounting tray 19 (the region 41 shown in FIG. 3B), and the upper surface of the object 26 to be heated. By performing heating limited to the placement position of the object to be heated at the same time from the bottom surface, highly efficient cooking and cooking time can be shortened.
上下同時加熱による効果として、上面加熱、下面加熱を別々に行うよりも、被加熱物に対して効率よく加熱ができることが挙げられる。 The effect of simultaneous heating up and down is that the object to be heated can be heated more efficiently than when the top surface heating and the bottom surface heating are performed separately.
これは、例えば上面加熱のみでは、被加熱物の下面からの放熱が大きくなることから、被加熱物の温度が上昇しにくくなり結果的に調理時間が延びるからである。 This is because, for example, only the upper surface heating increases heat radiation from the lower surface of the object to be heated, so that the temperature of the object to be heated is less likely to rise, resulting in a longer cooking time.
なお、上面加熱手段としては、管ヒータに限らず、面ヒータ、マイクロ波発生手段および誘導加熱手段を用いても良い。 The upper surface heating means is not limited to a tube heater, and a surface heater, microwave generation means, and induction heating means may be used.
また、マグネトロン２３からのマイクロ波は、すべてが載置皿１９の裏面に供給されるわけではなく、一部は載置皿１９の上方の空間に供給される。そのため、載置皿１９の上方の空間に供給されたマイクロ波により、被加熱物２６は、その内部がマイクロ波加熱される。 Further, not all of the microwaves from the magnetron 23 are supplied to the back surface of the mounting tray 19, and a part is supplied to the space above the mounting tray 19. Therefore, the inside of the object to be heated 26 is microwave-heated by the microwave supplied to the space above the mounting tray 19.
図４は、図１の加熱調理器１の加熱室２内の断面を扉３側からみた概略図である。下面加熱手段であるマグネトロン２３から発生したマイクロ波は、導波管３０によりアンテナ１３に供給され、アンテナ１３および下方加熱制御部１１により載置皿１９における被加熱物２６の載置箇所へ集中的に照射される。 FIG. 4 is a schematic view of a cross section in the heating chamber 2 of the heating cooker 1 of FIG. 1 viewed from the door 3 side. The microwave generated from the magnetron 23 serving as the lower surface heating means is supplied to the antenna 13 through the waveguide 30, and concentrated on the place where the object to be heated 26 is placed on the placement tray 19 by the antenna 13 and the lower heating control unit 11. Is irradiated.
アンテナ１３を制御することで載置皿１９における被加熱物２６の載置箇所に集中したマイクロ波により、被加熱物２６の直下付近のマイクロ波吸収発熱体７が発熱することで被加熱物２６の下面に焼き色を付けるような調理ができ、さらにマイクロ波加熱の特徴である被加熱物２６の内部への直接加熱と、上面からの管ヒータ１４ａ、１４ｂ、１４ｃによって、調理時間の短縮と調理の良好な仕上がりを確保することができる。 By controlling the antenna 13, the microwave absorbing heating element 7 immediately below the heated object 26 generates heat due to the microwaves concentrated on the place where the heated object 26 is placed on the placing plate 19, so that the heated object 26. It is possible to perform cooking so that the lower surface of the glass is baked, and further, by directly heating the inside of the object to be heated 26, which is a feature of microwave heating, and shortening the cooking time by the tube heaters 14a, 14b, 14c from the upper surface A good finish of cooking can be ensured.
図２、図３および図４において、下方からの加熱領域を限定する方法として、アンテナ１３の回転方向と回転速度を制御して、被加熱物２６の方向またはその前後にアンテナ１３が向いている場合は、それ以外の場合と比べてアンテナ回転速度を遅くしたり、マグネトロン２３への電力を増加させたりする方法がある。これにより、被加熱物２６への熱量を増加させ、調理時間を短縮することができる。 2, 3, and 4, as a method for limiting the heating region from below, the rotation direction and rotation speed of the antenna 13 are controlled so that the antenna 13 faces in the direction of the object to be heated 26 or in front of and behind it. In such a case, there are methods of slowing the antenna rotation speed or increasing the power to the magnetron 23 as compared to other cases. Thereby, the calorie | heat amount to the to-be-heated material 26 can be increased, and cooking time can be shortened.
また、アンテナ１３の方向に関して、一定の範囲（例えば、アンテナ１３が扉３の右端に向かう方向から扉３の左端に向かう方向までの間）を往復させるなど、加熱領域の限定の方法にはいろいろな場合が考えられる。 There are various methods for limiting the heating area, such as reciprocating a certain range (for example, between the direction in which the antenna 13 is directed toward the right end of the door 3 and the direction in which the antenna 13 is directed toward the left end of the door 3). There may be cases.
図２および図３において、定格電流値の範囲内で、上面加熱手段である管ヒータ１４ａ、１４ｂ、１４ｃとマグネトロン２３の電力配分を行う必要がある。 2 and 3, it is necessary to distribute power between the tube heaters 14a, 14b, 14c, which are upper surface heating means, and the magnetron 23 within the range of the rated current value.
一例としては、１００Ｖ−１５Ａ時の定格許容電力値１５００Ｗのうち、上面重視の加熱時は８３０Ｗを上面加熱手段へ、残りのうち５００Ｗ程度をマイクロ波発生手段への入力にあてる。また、下面重視の加熱時は４００Ｗを上面加熱手段にあてて、残りのうちの
８４０Ｗをマイクロ波発生手段への入力にあてることが考えられる。
As an example, out of the rated allowable power value of 1500 W at 100V-15A, 830 W is input to the upper surface heating means when heating with importance on the upper surface, and the remaining 500 W is input to the microwave generating means. Further, it is conceivable that 400 W is applied to the upper surface heating means during the heating with emphasis on the lower surface, and the remaining 840 W is applied to the input to the microwave generating means.
また、被加熱物の種類によって各加熱手段の出力を変化させる制御や、加熱時間の制御も考えられる。例えば、トースト調理などでは、加熱初期はマイクロ波加熱の出力を大きくして加熱して水分を減らし、その後、上面加熱手段の出力を大きくすることで、表面に焼き色をしっかり付け、焼き上げることができる。 Further, control for changing the output of each heating means depending on the type of the object to be heated, and control of the heating time can be considered. For example, in toast cooking, in the initial stage of heating, the output of microwave heating is increased to reduce moisture by heating, and then the output of the upper surface heating means is increased so that the surface is baked firmly and baked. it can.
このように、被加熱物２６の加熱過程で下面をより加熱したい場合には、管ヒータ１４ａ、１４ｃに通電せず、管ヒータ１４ｂのみ通電させると同時に、上面加熱手段で消費しなくなった電力の余剰分を用いて、定格許容電流値を超えない範囲でマイクロ波出力を可能な限り大きくすることで、載置皿１９のマイクロ波吸収発熱体７からの発熱量が増加するため、被加熱物２６の下面加熱が促進される。 Thus, when it is desired to further heat the lower surface during the heating process of the object to be heated 26, the tube heaters 14a and 14c are not energized, only the tube heater 14b is energized, and at the same time, the power consumed by the upper surface heating means is reduced. Since the amount of heat generated from the microwave absorption heating element 7 of the mounting tray 19 is increased by increasing the microwave output as much as possible within a range not exceeding the rated allowable current value using the surplus, the object to be heated The lower surface heating of 26 is promoted.
同様に、上面をより加熱させたい場合は、マイクロ波出力を弱めることにより生じる余剰電力を上面加熱手段に投入することで上面加熱の出力を上げ、被加熱物の上面加熱が促進させる。 Similarly, when it is desired to further heat the upper surface, surplus power generated by weakening the microwave output is input to the upper surface heating means to increase the output of the upper surface heating and promote the upper surface heating of the object to be heated.
被加熱物２６に応じて上記のように加熱構成の組み合わせを変更し、時間配分や入力電力配分を行うことで、被加熱物２６の仕上がりを良好にすること、および、調理時間の短縮が同時に実現することができる。 By changing the combination of heating configurations according to the object to be heated 26 and performing time distribution and input power distribution, the finish of the object to be heated 26 is improved and the cooking time is shortened at the same time. Can be realized.
以上のように、本発明はオーブン機能を有する電子レンジ等の加熱調理器に用いることができるものであり、被加熱物の載置位置に応じた加熱領域に対して、上面加熱手段、マイクロ波加熱、および、被加熱物の載置皿からの発熱によって、上下面から同時に加熱することで、高効率な調理を行うことができる。 As described above, the present invention can be used in a heating cooker such as a microwave oven having an oven function, and the upper surface heating means, the microwaves are applied to the heating region corresponding to the placement position of the object to be heated. High-efficiency cooking can be performed by simultaneously heating from the upper and lower surfaces by heating and heat generation from the placing plate of the object to be heated.
載置皿にはマイクロ波吸収発熱体が貼付されており、マイクロ波加熱によって被加熱物の底面を高温にすることにより、フライパンで焼くような効果が得られ被加熱物の仕上がりを良くすることができる。 A microwave-absorbing heating element is affixed to the mounting plate, and by heating the bottom of the object to be heated by microwave heating, the effect of baking with a frying pan is obtained, and the finish of the object to be heated is improved. Can do.
これら３種類の加熱方法を同時に、加熱領域を絞って用いることで、調理時間の短縮、消費電力の低減が可能となるので、上面加熱手段として面ヒータなどを用いて、より加熱領域を分割して細かく領域を選択できるようにすることで、被加熱物に加熱むらが発生しても調理時間内に加熱状況を検知し加熱構成を変化させ、加熱不足の部分に集中加熱するなど、調理性能を向上させることができる。 By simultaneously using these three types of heating methods by narrowing the heating area, cooking time can be shortened and power consumption can be reduced. Therefore, the heating area can be further divided by using a surface heater or the like as the upper surface heating means. By making it possible to select the area in detail, the cooking performance can be detected by detecting the heating status within the cooking time and changing the heating configuration within the cooking time even if uneven heating occurs in the object to be heated. Can be improved.
