Abstract
(EN)
A refrigerator (10), wherein an air return duct (30) for a freezing compartment thereof consists of a heat-insulating partition wall (19) and partition walls (21, 25) that are provided at the rear of the freezing compartment as well as a cold-air forcing plate (51) which is provided at a lower end (21A) of the partition wall (21). By means of the described structure, the air return duct (30) of the freezing compartment is not shaped as a tunnel that passes through the heat-insulating partition wall (19), which reduces the number of components and reduces the overall costs of the refrigerator. In addition, the use of a reinforcing rib (53) to strengthen the cold-air forcing plate (51) may prevent the cold-air forcing plate (51) from generating noise.

L'invention concerne un réfrigérateur (10), dans lequel un conduit de retour d'air (30) pour un compartiment de congélation de celui-ci, est constitué d'une paroi de séparation thermo-isolante (19) et de parois de séparation (21, 25) qui sont disposées à l'arrière du compartiment de congélation ainsi qu'une plaque de contrainte d'air froid (51) qui est disposée au niveau d'une extrémité inférieure (21A) de la paroi de séparation (21). Au moyen de la structure décrite, le conduit de retour d'air (30) du compartiment de congélation n'est pas en forme de tunnel qui traverse la paroi de séparation thermo-isolante (19), ce qui réduit le nombre de composants et réduit les coûts globaux du réfrigérateur. De plus, l'utilisation d'une nervure de renfort (53) pour renforcer la plaque de contrainte d'air froid (51) peut empêcher la plaque de contrainte d'air froid (51) de produire du bruit.

一种冰箱(10),其冷冻室回风风道(30)由设置在冷冻室(15)后方的隔热分隔壁(19)、分隔壁(21、25)以及设置在分隔壁(21)下端(21A)的冷气强制板(51)构成。通过该结构,冷冻室回风风道(30)并非贯穿隔热分隔壁(19)的隧道形状,可减少部件数量,降低冰箱整体成本。此外,利用加强肋(53)强化冷气强制板(51),可防止冷气强制板(51)产生噪音。
