Abstract

La présente invention se rapporte au domaine des appareils ménagers. L'invention concerne une hotte de cuisine à aspiration par le haut et un élément d'assemblage auxiliaire et une structure de montage intégrée et un procédé associé. La hotte de cuisine à aspiration par le haut comprend : une hotte de collecte de fumée, une cavité de collecte de fumée étant formée et une admission de graisse et de fumée étant formée au niveau du fond de la cavité de collecte de fumée ; une plaque collectrice de fumée couvrant l'admission de graisse et de fumée et pouvant être tournée vers une direction avant inférieure ; et un panneau de commande dissimulé dans une zone d'extrémité avant du fond de la cavité de collecte de fumée et pouvant être tourné vers le bas. Lorsque la hotte de cuisine à aspiration par le haut fonctionne, la plaque de collecte de fumée qui couvre à l'origine l'admission de graisse et de fumée peut être tournée vers la direction avant inférieure pour rassembler la vapeur de cuisson vers une zone arrière de la plaque de collecte de fumée et réduire la dispersion externe de la vapeur, de sorte qu'un utilisateur n'a pas besoin d'éviter de manière ciblée une vapeur à haute température, ce qui permet d'éviter l'inconfort et de réduire considérablement le risque de brûlure. De plus, par rapport à des hottes de cuisine classiques, la hotte de cuisine à aspiration par le haut de la présente invention est innovante et extrêmement attractive en termes d'aspect et peut améliorer l'expérience de l'utilisateur ; et au moyen de l'élément d'assemblage auxiliaire, un positionnement et un montage rapides de la hotte de cuisine à aspiration par le haut peuvent être obtenus, ce qui permet d'améliorer efficacement l'efficacité de montage et de réduire les coûts.
