Description
【発明の詳細な説明】 ［産業上の利用分野］ 本発明は、バーナからの燃焼熱気により調理を行なう
加熱調理器に関する。TECHNICAL FIELD The present invention relates to a heating cooker that cooks by burning hot air from a burner.

ファンを設けたものが提案されている。[Prior Art] Conventionally, in a heating cooker using a burner, as described in, for example, Japanese Utility Model Publication No. 59-33937, while a circulation fan is provided in the heating chamber, the heating chamber is heated by combustion hot air from the burner. It has been proposed to provide an exhaust fan that indirectly heats the air and draws hot combustion air into the air passage outside the heating chamber and discharges the air to the outside.

じ、その結果として調理時間が長くならざるを得ない。[Problems to be Solved by the Invention] However, the above-described heating cooker is an indirect heating type, and does not introduce the air heated by the burner into the heating chamber,
Since the air is discharged to the outside through the air passage on the outside of the heating chamber, it is inevitable that the temperature rise in the heating chamber is inferior to that of the direct heating type. Therefore, if this is combined with a microwave oven to form a compound cooker, when high-frequency heating and heating by combustion are used together, it is necessary to reduce the output of high-frequency heating in accordance with the rise of combustion heating. As a result, it takes longer to cook.

が期待できる。On the other hand, as disclosed in Japanese Utility Model Publication No. Sho 63-22409, in the compound cooker, a part of the cooling air of the cooling fan provided in the high frequency oscillator for high frequency heating is supplied to the burner side in the combustion chamber. Then, what introduces combustion hot air directly into a heating chamber is proposed. According to this, since the combustion hot air is directly introduced into the heating chamber by utilizing a part of the cooling air, it can be expected that the rise of the combustion heating is improved as compared with the above case.

だ十分なものとすることができない。However, in the above-described combined cooker, since a part of the cooling air is used, the combustion hot air cannot be sufficiently and forcibly introduced into the heating chamber. In addition, the combustion hot air is introduced into the heating chamber from the back of the circulation fan. With this configuration, if the air flow rate of the cooling fan is increased to promote the introduction of the combustion hot air, the circulation fan will operate. Since a hindrance occurs, a large amount of combustion hot air cannot be introduced. Therefore, the improvement of the rise of combustion heating cannot be sufficiently improved.
そして、加熱室内の空気の循環は循環ファンによって
のみ行われるので、循環ファンから離れる程、即ち、加
熱室の内奥になる程、熱気の分布が均一となりにくく、
一層の均一化が望まれている。And, since the circulation of air in the heating chamber is performed only by the circulation fan, the farther from the circulation fan, that is, the deeper the inside of the heating chamber, the more difficult the uniform distribution of hot air becomes,
Further homogenization is desired.

Utilizing the fact that the combustion hot air is forcibly supplied to the heating chamber makes it possible to improve the rise of the combustion heating in the heating chamber and to make the distribution of the hot air in the entire heating chamber uniform. To realize things.
