Abstract

La présente invention concerne un réfrigérateur et une structure à trajet d'air froid pour un réfrigérateur. La structure à trajet d'air froid comporte une sortie d'air froid, une entrée d'air froid, un conduit d'air froid et un élément amortisseur. La sortie d'air froid est définie dans un compartiment congélateur pour évacuer l'air froid du compartiment congélateur. L'entrée d'air froid est définie dans un compartiment de réfrigération pour admettre l'air froid évacué de la sortie d'air froid à l'intérieur du compartiment de réfrigération. Le conduit d'air froid définit un passage pour que l'air froid le traverse de la sortie d'air froid à l'entrée d'air froid. L'élément amortisseur est disposé de manière rotative entre la sortie d'air froid et le conduit d'air froid. Dans cette configuration, l'air froid peut être transféré de manière uniforme du compartiment congélateur aux zones supérieure et inférieure du compartiment de réfrigération. De même, étant donné que l'amenée d'air froid peut être réglée séparément en fonction des températures dans les zones supérieure et inférieure du compartiment de réfrigération, il est possible de réduire l'absence d'uniformité de la température dans le compartiment de réfrigération.
