次に、上記構成からなる加熱装置について、その動作、作用を説明する。 Next, the operation | movement and effect | action are demonstrated about the heating apparatus which consists of the said structure.
図3、図4は、加熱室10内に被加熱物載置皿22を設置した場合の一状態を示すもので、図3は上段に設置した状態、図4は中段に設置した状態を示している。 FIGS. 3 and 4 show one state when the heated object mounting tray 22 is installed in the heating chamber 10, FIG. 3 shows a state where it is installed in the upper stage, and FIG. 4 shows a state where it is installed in the middle stage. ing.
図3に示すように、水平部23aに被加熱物載置皿22を設置すると、加熱室10は加熱室10aと加熱室10bの空間に分離される。これにより載置台12に被加熱物を載せて被加熱物を加熱調理する場合は、加熱室の容積が小さくなる。切り替え手段19cで流路が矢印32のようにした状態で蒸気発生手段17を動作させると、飽和蒸気が加熱室10b内に充満する。蒸気発生手段17で発生する蒸気量が同じ場合は加熱室10内の蒸気密度が大きくなり。飽和蒸気により被加熱物を短時間で最適に加熱することが出来る。 As shown in FIG. 3, when the heated object mounting tray 22 is installed in the horizontal portion 23a, the heating chamber 10 is separated into a space between the heating chamber 10a and the heating chamber 10b. Thereby, when mounting a to-be-heated material on the mounting base 12 and cooking a to-be-heated material, the volume of a heating chamber becomes small. When the steam generation means 17 is operated in a state where the flow path is as indicated by the arrow 32 by the switching means 19c, the saturated steam fills the heating chamber 10b. When the amount of steam generated by the steam generating means 17 is the same, the steam density in the heating chamber 10 increases. The object to be heated can be optimally heated in a short time by saturated steam.
また、切り替え手段19cで流路が矢印33のようにした状態で蒸気発生手段18を動作させると、過熱蒸気を加熱室10b内の一部分に集中させて噴射することが出来る。 Further, when the steam generating means 18 is operated in the state where the flow path is as indicated by the arrow 33 by the switching means 19c, the superheated steam can be concentrated and injected on a part of the heating chamber 10b.
さらに、上記状態のそれぞれでマグネトロン16、モータ26を動作させ、加熱室10内にマイクロ波を供給すると、被加熱物が直接加熱されるとともに、発熱体にも吸収され被加熱物載置皿22も加熱される。被加熱物載置皿22の裏側の発熱体22bや載置台12などには、飽和蒸気が付着して結露している場合は、結露して付着した水が直接加熱、或いは伝熱により加熱され、再び蒸気となり、被加熱物の加熱に用いられる。 Further, when the magnetron 16 and the motor 26 are operated in each of the above states and the microwave is supplied into the heating chamber 10, the object to be heated is directly heated and also absorbed by the heating element 22. Is also heated. When saturated steam adheres to the heating element 22b or the mounting table 12 on the back side of the heated object placing tray 22 and the condensed water is condensed, the condensed and attached water is heated directly or by heat transfer. It becomes steam again and is used to heat the object to be heated.
図4に示すように、水平部24aに被加熱物載置皿22を設置すると、加熱室10は加熱室10cと加熱室10dの空間に分離される。また、被加熱物載置皿22の上に載せて被加熱物を加熱調理する場合は、切り替え手段19cで流路が矢印33のようにした状態で蒸気発生手段18を動作させるようにすることで、噴射口18eから直接、蒸気を被加熱物に吹き付けるようになる。この際、加熱部18cの通電動作により噴射する蒸気の温度を可変することが出来、100℃以上の温度とすることも可能で過熱蒸気とすることも出来る。数量の少ない被加熱物を短時間で加熱するのに適している。 As shown in FIG. 4, when the heated object mounting tray 22 is installed in the horizontal portion 24a, the heating chamber 10 is separated into a heating chamber 10c and a heating chamber 10d. In addition, when the object to be heated is to be cooked by placing it on the object to be heated platen 22, the steam generation means 18 is operated with the switching means 19 c with the flow path as indicated by the arrow 33. Thus, steam is blown directly onto the object to be heated from the injection port 18e. At this time, the temperature of the sprayed steam can be varied by the energization operation of the heating unit 18c, and can be set to a temperature of 100 ° C. or higher, and can be superheated steam. Suitable for heating a small quantity of heated objects in a short time.
さらに、この状態でマグネトロン16、モータ26を動作させ、加熱室10内にマイクロ波を供給すると、発熱体22bが昇温し、その伝熱により被加熱物が下方から伝熱加熱され、焦げ目をつけることが出来る。この際マイクロ波の大部分は金属製の被加熱物載置皿22で遮蔽され発熱体22bで吸収されることで被加熱物には入り難くなっている。またこの状態の後、加熱手段30を通電することにより、天面29側から輻射熱が被加熱物に与えられ、被加熱物上側に焦げ目をつけることもできる。 Further, when the magnetron 16 and the motor 26 are operated in this state and microwaves are supplied into the heating chamber 10, the heating element 22b rises in temperature, and the object to be heated is heat-transferred and heated from below by the heat transfer. You can turn it on. At this time, most of the microwave is shielded by the metal heated object mounting tray 22 and absorbed by the heating element 22b, so that it is difficult to enter the heated object. Further, after this state, the heating means 30 is energized so that radiant heat is applied to the object to be heated from the top surface 29 side, and the upper side of the object to be heated can be burnt.
また、これにより載置台12に被加熱物を載せて被加熱物を加熱調理する場合は、加熱室の容積がさらに小さくなる。切り替え手段19cで流路が矢印32のようにした状態で蒸気発生手段17を動作させると、飽和蒸気が加熱室10b内に早く充満する。 Moreover, when this puts a to-be-heated material on the mounting base 12 and heats a to-be-heated material, the volume of a heating chamber becomes still smaller. When the steam generating means 17 is operated in the state where the flow path is as indicated by the arrow 32 by the switching means 19c, the saturated steam is quickly filled in the heating chamber 10b.
さらに、この状態でマグネトロン16、モータ26を動作させ、加熱室10内にマイクロ波を供給すると、被加熱物が直接加熱されるとともに、発熱体にも吸収され被加熱物載置皿22も加熱される。 Further, when the magnetron 16 and the motor 26 are operated in this state and the microwave is supplied into the heating chamber 10, the object to be heated is directly heated, and the object to be heated is also absorbed by the heating element and heated. Is done.
さらに、被加熱物載置皿22の上、載置台12の上に別々の被加熱物を置いて、異なる加熱シーケンスで調理を行ない。仕上がりを同時にすることも出来る。 Further, separate heated objects are placed on the heated object placing tray 22 and the placing table 12, and cooking is performed in different heating sequences. You can also finish at the same time.
なお、これまでの実施の形態においては、蒸気発生部を2有する場合で代表して説明したが、必要に応じて3以上設けてもよい。また、その際には係止手段の数も増やしてよく、場合によっては被加熱物載置皿も複数用いてもよい。 In the embodiments described so far, the case where there are two steam generation units has been described as a representative example, but three or more may be provided as necessary. Moreover, in that case, the number of locking means may be increased, and in some cases, a plurality of objects to be heated may be used.
以上のように本発明によれば、複数の蒸気発生装置を備えるとともに、加熱室内の空間を仕切ることで、被加熱物の大きさ、形状など応じて、様々な調理方法が実現できる。オーブンレンジ、オーブンあるいはグリラーはもとより、半導体装置、乾燥装置などの工業分野での加熱装置にも展開することができる。 As described above, according to the present invention, various cooking methods can be realized according to the size and shape of the object to be heated by providing a plurality of steam generators and partitioning the space in the heating chamber. The present invention can be applied not only to a microwave oven, an oven, or a griller, but also to heating devices in industrial fields such as semiconductor devices and drying devices.
