A drum type washing machine comprising: a cabinet; a bottomed cylindrical water tub having a water tub opening, placed inside the cabinet; a bottomed cylindrical rotating drum having a drum opening, placed inside the water tub; a motor attached to an outer bottom surface of the water tub for rotating the rotating drum on a rotation axis horizontal or tilted down toward the bottom of the rotating drum; a circulation tube communicatively connecting a bottom side of the water tub with a side of the water tub opening for circulating washing water in the water tub from the bottom side to the side of the water tub opening; a plurality of ejection holes for ejecting the washing water circulated through the circulation tube toward the inside of the rotating drum; a water duct at a front-surface wall of the water tub, connected to the circulation tube; and a plurality of discharge outlets in the water duct for discharging the washing water between an inside surface of the front-surface wall of the water tub and an outside surface of a front-surface wall of the rotating drum; characterized in that: the washing machine further comprises a plurality of guide surfaces (56 to 59, 61 to 64) formed on the inside surface of the front-surface wall of the water tub for guiding the washing water discharged from the discharge outlets to the ejection holes, wherein the guide surfaces (56 to 59, 61 to 64) have shapes different from each other such that the washing water ejected from each ejection hole has a different diffusion angle when viewed from a front side of the washing machine, and a different angle when viewed from a side of the washing machine. a cabinet; a bottomed cylindrical water tub having a water tub opening, placed inside the cabinet; a bottomed cylindrical rotating drum having a drum opening, placed inside the water tub; a motor attached to an outer bottom surface of the water tub for rotating the rotating drum on a rotation axis horizontal or tilted down toward the bottom of the rotating drum; a circulation tube communicatively connecting a bottom side of the water tub with a side of the water tub opening for circulating washing water in the water tub from the bottom side to the side of the water tub opening; a plurality of ejection holes for ejecting the washing water circulated through the circulation tube toward the inside of the rotating drum; a water duct at a front-surface wall of the water tub, connected to the circulation tube; and a plurality of discharge outlets in the water duct for discharging the washing water between an inside surface of the front-surface wall of the water tub and an outside surface of a front-surface wall of the rotating drum; the washing machine further comprises a plurality of guide surfaces (56 to 59, 61 to 64) formed on the inside surface of the front-surface wall of the water tub for guiding the washing water discharged from the discharge outlets to the ejection holes, wherein the guide surfaces (56 to 59, 61 to 64) have shapes different from each other such that the washing water ejected from each ejection hole has a different diffusion angle when viewed from a front side of the washing machine, and a different angle when viewed from a side of the washing machine.
