Claims (2)
- 密閉容器内に、潤滑油と、冷媒ガスを吸入して圧縮する圧縮要素と、該圧縮要素を駆動する電動要素とを収容した密閉型圧縮機において、
前記圧縮要素の冷媒吸入ポートに吸込みマフラを有し、該吸込みマフラは、前記密閉容器内に開口されて前記密閉容器内の前記冷媒ガスを吸入する吸込み口と、前記吸込み口から前記圧縮要素の吸込み部へ連通する通路部とを有し、前記吸込み口と前記通路部の係合部を一体形状として前記潤滑油の流入を抑制する構成として、前記吸込み口と前記通路部を一体形状とした前記吸込みマフラの底部に潤滑油排出孔を有し、
前記吸込みマフラの前記吸込み口上部に油受け部を設け、前記吸込み口上部の前記油受け部の底部は傾斜を有し、前記油受け部の前記底部に溜まった前記潤滑油は前記傾斜に沿って流れ落ちた後に前記吸込み口の横面を流すことで、前記吸込みマフラの前記吸込み口への前記潤滑油の流入を低減することを特徴とする密閉型圧縮機。 - 冷蔵庫本体に形成された貯蔵室と、該貯蔵室と断熱区画された機械室と、を備え、請求項1に記載の密閉型圧縮機を前記機械室に備えたことを特徴とする冷蔵庫。
