CA 2258777

A refrigerator provided with an air curtain generator in a refrigerating room (200) is disclosed. A supply duct (42) for an air curtain is installed at the uppermost portion of the refrigerating room. A crossflow fan (44) is provided within the supply duct, and a supply port (43) is formed at a terminal end of the supply duct (42) adjacent to a door for the refrigerating room. The supply port (43) is slit-shaped and extends along a width direction of the refrigerating room. At least one step is provided on a lower surface of the inside of the supply duct. The supply duct (42) is communicated with a suction duct (47) constituting a cooling system of the refrigerator. When the door is opened, the air curtain is formed over the open side of the refrigerating room (300) to block the invasion of the surrounding air.

L'invention a trait à un réfrigérateur comportant un générateur de rideau d'air dans l'enceinte de réfrigération (200). Un conduit de distribution (42) d'air en rideau se trouve dans la partie la plus haute de l'enceinte de réfrigération. Une soufflante à flux transversal (44) est en place dans le conduit de distribution et un orifice de distribution (43) se trouve à l'extrémité de ce conduit (42) contigu à la porte de l'enceinte de réfrigération. Cet orifice de distribution (43), ayant l'aspect d'une fente, se présente transversalement à l'enceinte de réfrigération. La face inférieure de l'intérieur du conduit de distribution comporte au moins un décrochement. Ce conduit de distribution (42) communique avec un conduit d'aspiration (47), tous deux constituant le circuit de réfrigération du réfrigérateur. Lorsque la porte du réfrigérateur est ouverte, il se forme un rideau d'air au-dessus du coté béant de l'enceinte de réfrigération (220) qui empêche l'entrée de l'air environnant.
