Abstract

La présente invention concerne un appareil de cuisson par chauffage permettant une réduction de temps de chauffage en réduisant le temps nécessaire pour accroître la température de l'enceinte de chauffage à une température souhaitée. Étant donné que la distance entre une source de chaleur (3) en forme de serpentin pour réchauffer l'air dans une enceinte de source de chaleur (30) et dans un ventilateur de circulation (32) est inférieure à 10 mm, l'efficacité de la circulation d'air est accrue. Étant donné qu'un revêtement (25) est formé sur une surface latérale de l'enceinte de source de chaleur (30) d'une plaque de séparation (22) qui constitue la limite entre l'enceinte de source de chaleur (30) et l'enceinte de chauffage (20), la chaleur provenant de la source de chaleur (31) s'accumule dans le revêtement (25). La chaleur est rayonnée depuis le revêtement (25) et réchauffe l'air dans l'enceinte de source de chaleur (30) sous la forme d'une seconde source de chaleur. Par conséquent, lorsque l'air chaud réchauffé par la source de chaleur (31) dans l'enceinte de source de chaleur (32) est alimenté dans l'enceinte de chauffage (20) par le ventilateur de circulation (32) pour la cuisson, le temps nécessaire pour accroître la température de l'air dans l'enceinte de source de chaleur (30) à une température prédéterminée peut être réduite, et l'énergie pour le traitement thermique peut être économisée.
