Description

このような課題を解決する本発明のドラム式洗濯機は、内部に水を溜める外槽と、前記外槽内に回転自在に支持され、衣類が収容されるドラムと、前記ドラムを回転駆動するドラムモータと、前記外槽内に給水する給水手段と、前記外槽から水を吸い込み、前記ドラム内に向かって散水するように水を循環させる循環ポンプと、を備え、前記循環ポンプは、前記ドラム内への散水時に前記外槽から前記ドラム内に向かって水を送出するように回転する羽根車を備え、前記羽根車は、回転軸の周りに複数並んで放射状に配置される板体で形成される羽根を有し、前記羽根のそれぞれは、前記回転軸側から放射方向に向けて湾曲し、この湾曲面は、前記羽根車の回転方向に凸となっていることを特徴とする。 The drum type washing machine of the present invention that solves such a problem includes an outer tub that stores water therein, a drum that is rotatably supported in the outer tub, and stores clothes, and rotationally drives the drum. A drum motor, water supply means for supplying water into the outer tub, and a circulation pump for sucking water from the outer tub and circulating water so as to sprinkle water into the drum. An impeller that rotates to send water from the outer tub toward the inside of the drum when water is sprayed into the drum, and the impeller is a plate body that is arranged radially around a rotation axis. has a blade to be formed, each of the vanes, curved toward from the rotating shaft side in the radial direction, the curved surface, characterized in that it is convex in the rotation direction of the impeller.
