【考案の詳細な説明】 本考案は高周波加熱源と電気ヒータ等の外部加熱源とを
有する調理器に関し、特に高周波加熱源を調理中の油煙
や熱から保護する仕切板の改良構造に関する。[Detailed Description of the Invention] The present invention relates to a cooking appliance having a high frequency heating source and an external heating source such as an electric heater, and more particularly to an improved structure of a partition plate that protects the high frequency heating source from oil smoke and heat during cooking.

、、この種の調理器の仕切板としては実開昭５２−１
４２２４ｉ号公報の如く金属製の固定板に透孔を設け、
この透孔にガラス等の電波透過性の小板を固定した゛も
のが知られている。,,As a partition plate for this type of cooker, the Utility Model 52-1
A through hole is provided in a metal fixing plate as in 4224i publication,
A device in which a small plate of glass or the like that transmits radio waves is fixed to this hole is known.

斯る構成の仕切板においては電波の透過率を良くするに
は透孔の面積を大きくする必要があり、こうすると小板
の強度を保つために厚みを厚くする必要がある。In a partition plate having such a structure, it is necessary to increase the area of the through holes in order to improve the transmittance of radio waves, and in this case, it is necessary to increase the thickness in order to maintain the strength of the small plates.

しかしながら、厚みを厚くすると電波透過率が悪くなり
、透過率を向上できないと共に材料費が高くなるという
欠点があった。However, when the thickness is increased, the radio wave transmittance deteriorates, and there is a drawback that the transmittance cannot be improved and the material cost increases.

本考案は上述の点に鑑み為されたもので、以下にその実
施例を図について説明する。The present invention has been devised in view of the above points, and embodiments thereof will be described below with reference to the drawings.

は高周波加熱源であるマグネトロンである。1 is a cooking chamber provided in the main body 2; 3 is a high-frequency irradiation chamber formed by partitioning the upper part of the cooking chamber 1 with a partition plate 4; 5 is a stirrer rotatably disposed within this irradiation chamber 3. ,6
is a magnetron which is a high frequency heating source.

尚、この調理室１には電気ヒータ等の外部加熱源（図示
せず）が設けられ、或いはその加熱源からの熱気が適宜
供給されるものである。The cooking chamber 1 is provided with an external heating source (not shown) such as an electric heater, or hot air from the heating source is appropriately supplied.

７に複数個の透孔９を互いに間隔を置いで穿設し、この
透孔９に夫々セラミック製の小板８を固着したものであ
る。As shown in FIG. 2, the partition plate 4 has a plurality of through holes 9 formed at intervals from each other in a metal fixing plate 7, and small ceramic plates 8 are fixed to each of the through holes 9. This is what I did.

この場合、小板８・・・は厚みが小さく、同じ電波透過

板８・・・の合計重量の方が経くなるという利点がある
。In this case, the small plates 8... have a small thickness, and there is an advantage that the total weight of the small plates 8... is longer than when using a single ceramic plate when the same radio wave transmission area is used.

実験によれば第３図の如＜６ｃｍ角のセラミック小板９

透過率において優れていることが立証された。According to the experiment, a small ceramic plate 9 of <6 cm square as shown in Fig. 3
The partition plate of the present invention uses 9 pieces of 18Crn and each plate has a thickness of 4 mm, and the conventional example uses one small plate of 18 Crn square made of the same material and 5 mm thick to obtain the same transmission area. Comparing the radio wave transmittance with an equivalent partition plate, the former is 94.1%.
In contrast, the latter was 86.0%, proving that the former is superior in radio wave transmittance.

又、小板８・・・間の金属部分は電波照射時にその電波
を攪拌するので調理室１内の電界モードを均一にするよ
う働き、焼きムラを解消させるものである。Further, the metal parts between the small plates 8 stir the radio waves when irradiated with the radio waves, so they work to make the electric field mode in the cooking chamber 1 uniform, thereby eliminating uneven cooking.

かくして、仕切板４は電気ヒータ等の外部加熱源が作動
した時には高周波照射室３内を熱的に保護すると共に、
調理中に飛散する油等から高周波照射室３内を保護する
。Thus, the partition plate 4 thermally protects the inside of the high-frequency irradiation chamber 3 when an external heating source such as an electric heater is activated, and
The inside of the high frequency irradiation chamber 3 is protected from oil etc. scattered during cooking.

そして、この仕切板４は適宜外されて洗浄される。The partition plate 4 is then removed and cleaned as appropriate.

きる。As described above, the cooking device according to the present invention has a metal fixing plate in which a plurality of through holes are bored at intervals, and a partition plate that partitions the high frequency heating source from the cooking chamber, and a metal fixing plate that is fixed to each of the through holes. Because it is composed of multiple radio wave transparent small plates, the strength can be maintained even if the thickness of the small plates is reduced.
By making the wall thinner, radio wave transmittance can be improved and cooking can be done more efficiently. Material costs can also be reduced and costs can be reduced.
