触不良を生じるという問題点があった。<Problems to be solved by the invention> By the way, since the damper 13 is closed at the time of heating the oven, when the food to be cooked containing a large amount of water is heated, the steam entering the air supply duct 7 is generated by the blower 10. Condensation is formed on the damper 13 and the inner wall of the inlet portion of the air supply duct 7 that are cooled by the wind, and drops as water drops. If there are electrical components near the area where the water drops fall, there is a problem that insulation failure, pressure resistance failure, and contact failure occur.
〈課題を解決するための手段〉 給気ダクト７の入口部に結露防止用通気口１７を設け
る。<Means for Solving the Problem> A dew condensation preventing vent 17 is provided at the inlet of the air supply duct 7.
通気口１７は通気流がダンパー１３と平行な面をなすよ
うに設けるのが望ましい。It is desirable that the ventilation hole 17 be provided so that the ventilation flow forms a plane parallel to the damper 13.
又、通気口１７の大きさは熱漏洩を極力小さくするため
結露防止に必要最小の大きさにする。Further, the size of the vent hole 17 is set to the minimum size necessary to prevent dew condensation in order to minimize heat leakage.
〈作用〉 通気口１７から吸排気される乾燥した空気の通気流１８
が結露を防止する。<Operation> Ventilation flow 18 of dry air sucked and exhausted from the vent 17
Prevents condensation.
又、通気流１８がダンパー１３のエアカーテンとなって
蒸気がダンパー１３に接触するのを阻止し結露を防止す
る。Further, the ventilation flow 18 serves as an air curtain of the damper 13 to prevent steam from coming into contact with the damper 13 and prevent dew condensation.
