Abstract

Un réfrigérateur comprend : un contenant interne pourvu d'une ouverture d'induction d'air ; un ensemble conduit d'air d'induction d'air, qui est situé dans le contenant interne et est pourvu d'un conduit d'air d'induction d'air raccordé à l'ouverture d'induction d'air ; et un ensemble conduit d'air de raccordement, qui est situé à l'extérieur du contenant interne et est pourvu d'un conduit d'air de raccordement raccordé à l'ouverture d'induction d'air, et est utilisé pour guider un écoulement d'air externe du contenant interne vers le conduit d'air d'induction d'air. Au moyen de la solution de la présente invention, le nombre d'évaporateurs d'un réfrigérateur à chambres multiples peut être réduit, la structure du réfrigérateur est simplifiée, et le coût de fabrication est réduit. En permettant l'insertion réciproque de l'ensemble conduit d'air d'induction d'air et de l'ensemble conduit d'air de raccordement au niveau de l'ouverture d'induction d'air, le conduit d'air d'induction d'air et le conduit d'air de raccordement communiquent l'un avec l'autre, de telle sorte que le moyen de raccordement de conduit d'air du réfrigérateur puisse être simplifié, l'efficacité d'assemblage soit améliorée, la précision d'assemblage entre l'ensemble conduit d'air d'induction d'air et l'ouverture d'induction d'air n'ait pas besoin d'être prise en considération, et la précision d'assemblage entre l'ensemble conduit d'air de raccordement et l'ouverture d'induction d'air n'ait pas besoin d'être prise en considération.
