Abstract
(EN)

PROBLEM TO BE SOLVED: To provide a refrigerator capable of securely suppressing an extreme decrease in cooling performance.

SOLUTION: A refrigerator provided with a cold air return duct 35 at a side part of a cooling chamber 14 so as to let a cooler 15 suck return cold air from a cold room from an opening 36 of a cooling chamber side face has a fin 37 lower rear side of a cooler 15, opposed to the opening of the cooling chamber side face, eliminate to provide a cooler return air passage 41. Consequently, the fin lower rear side of the cooler opposed to the opening of the cooling chamber serves as a fin-less cooler return flow passage to form a large space between an opening peripheral edge and a fin side face, so even if frost sticks to be deposited, a clogging state can be prevented. Therefore, the return cold air reliably flows in the cooling chamber to be sucked in between fins of the cooler from a cooler return air passage, and even if the cold air returning to the cooling chamber is considerably high in humidity, a cold air flow is not impeded by frost sticking, thereby suppressing an extreme decrease in cooling performance.

【課題】冷却性能の極端な低下を確実に抑制できる冷蔵庫の提供。
【解決手段】冷気戻りダクト35を冷却室14の側部に設けて冷蔵室からの戻り冷気を冷却室側面の開口36より冷却器15に吸い込ませる冷蔵庫において、前記冷却室側面の開口と対向する冷却器15のフィン37下部後側を無くして冷却器戻り風路41とした構成としてある。これにより、冷却室の開口と対向する冷却器のフィン下部後側はフィンの無い冷却器戻り風路となって開口周縁とフィン側面との間に大きな空間が形成されるような形となるので、霜が付着してもこれが堆積して目詰まり状態になることを防止することができる。したがって戻り冷気は確実に冷却室内に流れ込んで冷却器戻り風路より冷却器のフィン間へと吸い込まれるようになり、冷却室に戻る冷気がかなり高い湿度を含んでいても霜付着による冷気流れの阻害を防止し、冷却性能の極端な低下を抑制することができる。
