To provide a washing machine which prevents unevenness in washing and which improves washing performance.SOLUTION: A circulation water passage 10 is formed by a washing and dewatering tub 7 in which a pulsator 8 is rotatably disposed at a central bottom part and a circulation water passage cover 14, and from a pump chamber 19 formed on an outer periphery of a blade 18 of the pulsator 8, a washing liquid which has moved up in the circulation water passage 10 is discharged to the inside of the washing and dewatering tub 7 from a discharge port 11. A total area of holes 13 of the pulsator 8 is larger than a minimum cross-sectional area on the flow passage of the circulation water passage, and the minimum cross-sectional area on the flow passage of the circulation water passage is smaller than an area of the discharge port. Thereby, the washing liquid is sprayed with respect to laundry which has newly appeared on a water surface as a whole in a wide range, while pulling the laundry positioned above the water surface in the washing and dewatering tub into the water. Thus, unevenness in washing is solved, and washing performance can be improved.SELECTED DRAWING: Figure 1 【課題】洗いむらを防止して洗浄性能を向上する洗濯機を提供すること。【解決手段】中央底部にパルセータ８を回転自在に配設した洗濯兼脱水槽７と循環水路カバー１４で循環水路１０を形成し、パルセータ８の羽根１８の外周に形成したポンプ室１９から循環水路１０を上昇した洗濯液を吐出口１１より洗濯兼脱水槽７の内方に吐出させる。パルセータ８の孔１３の総面積が、循環水路の流路上における最小断面積よりも大きく、かつ、循環水路の流路上における最小断面積が、吐出口の面積よりも小さくすることで、洗濯兼脱水槽内の水面より上に位置する洗濯物を水面下に引き込みつつ、新たに水面上に出現させた洗濯物に対して全体に洗濯液を広範囲にかけることで洗いむらを改善し、洗浄性能を向上することができる。【選択図】図１
