PROBLEM TO BE SOLVED: To provide a drum-type washing machine capable of preventing clothing from being stiffened while securing washing performance.SOLUTION: The drum-type washing machine includes: an outer tub for storing water inside; a drum that is rotatably supported in the outer tub and is for accommodating clothing; and a circulation pump that sucks water from the outer tub and sprays it into the drum. It has an agitation process for rotating the drum while driving the circulation pump during washing operation. The agitation process includes a first agitation and a second agitation. In the first agitation, the drum is rotated at a number of rotation of 60 rpm or greater. In the second agitation, the drum is rotated at a number of rotation of less than 60 rpm. In the first agitation and/or the second agitation, the circulation pump is driven to set a circulation flow rate to 36 L/min or higher. 【課題】洗浄性能を確保しつつ衣類のごわつきを抑制するドラム式洗濯機を提供する。【解決手段】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循環ポンプと、を備え、洗い運転中に、前記循環ポンプを駆動しながら前記ドラムを回転させる攪拌工程を有し、前記攪拌工程は、第１の攪拌工程と、第２の攪拌工程とを備え、前記第１の攪拌工程時に、前記ドラムを６０ｒｐｍ以上の回転数で回転させ、前記第２の攪拌工程時に、前記ドラムを６０ｒｐｍ未満の回転数で回転させ、前記第１の攪拌工程時及び／又は前記第２の攪拌工程時に、前記循環ポンプを駆動して循環流量を３６Ｌ／ｍｉｎ以上とする。【選択図】図８
