Abstract
(EN)

PROBLEM TO BE SOLVED: To solve problems that a freezing chamber return air channel is formed on a heat insulation partition wall, a number of components increases, and costs for the whole refrigerator is hard to be reduced.

SOLUTION: In a refrigerator 10, a freezing chamber return air channel 30 is configured by using a heat insulation partition wall 19 arranged on a rear side of a freezing chamber 15, partition walls 21 and 25, and a cooling air forced plate 51 arranged at a lower end 21A of the partition wall 21. By this configuration, the freezing chamber return air channel 30 is not a tunnel shape penetrating the heat insulation partition wall 19, can reduce a number of components, and can reduce costs for the whole refrigerator. The cooling air forced plate 51 is reinforced by a rib 53, thereby suppressing generation of noise by the cooling air forced plate 51.

【課題】従来の冷凍冷蔵庫では、冷凍室戻り風路が断熱仕切壁に形成され、部品点数も増大し、冷蔵庫全体のコストを低減し難いという課題がある。
【解決手段】本発明の冷蔵庫10では、冷凍室戻り風路30は、冷凍室15の後方に配設される断熱仕切壁19、仕切壁21,25及び仕切壁21の下端21Aに配設される冷気強制プレート51を用いて構成されている。この構造により、冷凍室戻り風路30は、断熱仕切壁19を貫通するトンネル形状でなく、部品点数を低減でき、冷蔵庫全体のコストを低減することができる。また、冷気強制プレート51は、リブ53により補強されることで、冷気強制プレート51による騒音の発生を抑制できる。
