【考案の詳細な説明】
この考案は加熱室を内部あるいは外部からヒータによっ
て加熱し、焦げ日付機能あるいはオーブン機能を備える
ようにした高周波加熱装置に関するものである。[Detailed Description of the Invention] This invention relates to a high-frequency heating device that heats a heating chamber from the inside or outside with a heater and has a burnt date function or an oven function.
従来この種の加熱装置においては高周波発振時にその発
振源（マグネトロン）を冷却した風を加熱室内へ送り込
んでいるが、ヒータによる調理時は風が送り込まれてい
ないため加熱室内の高温の雰囲気が高周波発振源の方へ
逆流してその過熱を招き、寿命を縮めてしまう等の不具
合が起こっていた。Conventionally, this type of heating device sends air that cools the oscillation source (magnetron) into the heating chamber during high-frequency oscillation, but when the heater is used for cooking, no air is sent in, so the high-temperature atmosphere inside the heating chamber is generated by high-frequency oscillation. Problems such as flowing back toward the oscillation source caused it to overheat, shortening its lifespan.
この考案はかかる従来の欠点を除去した高周波加熱装置
を提供するものである。This invention provides a high frequency heating device that eliminates such conventional drawbacks.
以下この考案を図示実施例により説明すると、１は外ケ
ース２と底板３と加熱箱４とからなる本体で、加熱箱４
の内部には加熱室５が形成されている。This invention will be explained below with reference to the illustrated embodiment. Reference numeral 1 denotes a main body consisting of an outer case 2, a bottom plate 3, and a heating box 4;
A heating chamber 5 is formed inside.

拌室８と調理室９とをそれぞれ区画形成している。Reference numeral 6 denotes a door rotatably attached to the main body 1 to open and close the front opening of the heating chamber 5, and 7 a partition made of a durable and radio wave transparent material that is detachably provided in the heating chamber 5. A plate divides the inside of the heating chamber 5 into two upper and lower chambers, forming a radio wave stirring chamber 8 and a cooking chamber 9, respectively.

した風を吸気口２０へ案内する吸気ダクトである。10 is a gap formed between the front edge of the partition plate 7 and the inner surface of the door 6 when the partition plate 7 is installed, 11 and 12 are heaters provided at the upper and lower parts of the cooking chamber 9, and 13 is a gap inside the stirring chamber 8. 15 is a power feed port provided on the side wall of the stirring chamber 8; 16 is a waveguide connected to the outer surface of the power feed port; 17 is an oscillation antenna of the magnetron 18; 19 is the cooled part of the magnetron 18, 20
21 is an air inlet formed in the front side of the stirring chamber 8, and 21 is an air inlet between the cooled part 19 of the magnetron 18 and the inside of the waveguide 16 through a small hole (not shown) formed in the wall of the waveguide 16. A blower sends air through a duct 22, and an air intake duct 23 guides air that has cooled the portion 19 to be cooled to an intake port 20.
しかして前記給電口１５と吸気口２０とが互いにほぼ等
しい高さに設けられているため、マグネトロン１８の被
冷却部１９は当然吸気口２０より下方に位置している。Since the power supply port 15 and the intake port 20 are provided at approximately the same height, the cooled portion 19 of the magnetron 18 is naturally located below the intake port 20.
２４．２５は攪拌室８の天井面と調理室９の側面とにそ
れぞれ設けた排気孔、２６はこれらの排気孔から放出さ
れた空気を本体１外部へ案内する排気ダクトである。24 and 25 are exhaust holes provided in the ceiling of the stirring chamber 8 and the side of the cooking chamber 9, and 26 is an exhaust duct that guides the air released from these exhaust holes to the outside of the main body 1.
以上の構成において、今マグネトロン１８を駆動すると
送風機２１も運転されるので、導波管１６から給電口１
５を介して攪拌室８内へ高周波と送風が行われる。In the above configuration, when the magnetron 18 is now driven, the blower 21 is also operated, so the waveguide 16 is connected to the power supply port 1.
High frequency waves and air are blown into the stirring chamber 8 through the stirring chamber 5 .
そして高周波の電界分布を均一化するようにスターク１
３がその送風で回転せしめられる。Then, the Stark 1
3 is rotated by the blast of air.
一方吸気口２０から攪拌室８内へ風が吹込まれ、空隙１
０を通ってドア６の内面に沿って降下し、排気孔２５か
ら外部へ放出されるので、ドア６の内面のくもりを防止
し、さらに食品から発生した蒸気等を外へ運び去る。On the other hand, wind is blown into the stirring chamber 8 from the intake port 20, and the air gap 1
0 and descends along the inner surface of the door 6 and is discharged to the outside from the exhaust hole 25, thereby preventing the inner surface of the door 6 from becoming cloudy and further carrying away steam generated from the food to the outside.
次にマグネトロン１８を停止し、ヒータ１１，１２の少
なくとも何れか一方に通電すると調理室９内に焙焼調理
が行える。Next, when the magnetron 18 is stopped and at least one of the heaters 11 and 12 is energized, roasting and cooking can be performed in the cooking chamber 9.
このとき送風機２１は運転されていないので、熱気の一

で、マグネトロン１８までへの熱気の逆流は殆んど起こ
らない。Since the blower 21 is not operating at this time, a portion of the hot air passes through the gap 10 and exits from the intake port 20 to the magnetron 18.
However, since the intake duct 23 is inclined to become lower toward the magnetron 18, the hot air hardly flows back to the magnetron 18.
また給電口１５から熱気が侵入することについては、仕
切板７により電波攪拌室８の温度はそれほど上らないこ
とから侵入してもほとんど問題はない。Further, regarding hot air entering from the power supply port 15, there is almost no problem even if the hot air enters because the temperature of the radio wave stirring chamber 8 does not rise much due to the partition plate 7.
また排気孔２４も設けられているので、より攪拌室８の
雰囲気温度は低く保たれる。Further, since the exhaust hole 24 is also provided, the atmospheric temperature of the stirring chamber 8 can be kept lower.

りや結露等が防止される。As mentioned above, this idea uses a heater to heat the heating chamber, so it can be used in conjunction with high frequency to efficiently perform various types of cooking. At the same time, since the air from the blower is blown into the heating chamber during high frequency cooking, it is possible to This prevents fogging and condensation on the viewing window.

冷却部に作用して、その熱破損や動作不良を招くという
心配もない実用上天なる効果がある。Moreover, since the cooled part of the magnetron is located below the position of the air inlet, which serves as the air intake, and in a position that does not face the air intake, hot air from the heater acts on the cooled part of the magnetron. There is no need to worry about thermal damage or malfunction, and it has a heavenly effect in practical terms.
