PROBLEM TO BE SOLVED: To provide a drum-type washing machine capable of increase accuracy of load quantity detection.SOLUTION: The drum-type washing machine includes: an outer tub disposed in a housing; a drum that is disposed in the outer tub and is rotatable about an inclined axis inclined with respect to a horizontal direction; a rotor disposed at a rear part of the drum and has a protrusive portion on a surface to contact laundry; a drive part capable of performing an operation in a biaxial drive mode in which the drum and the rotor are rotated at a different speed of rotation from each other and an operation in a uniaxial drive mode in which the drum and the rotor are rotated integrally at a same speed of rotation; and a controller. The controller operates the drive part in the biaxial drive mode so that the drum can be rotated in an accelerated manner to an attach speed at which laundry can be attached to an inner peripheral surface of the drum and, based on the rotation loads on the drum and on the rotor that is rotated relatively to the drum when the drum is rotated in the accelerated manner to the attach speed, detects the load quantity of the laundry in the drum (S11, S12).SELECTED DRAWING: Figure 10 【課題】負荷量検知の精度を高めることができるドラム式洗濯機を提供する。【解決手段】ドラム式洗濯機は、筐体内に配置された外槽と、外槽内に配置され、水平方向に対して傾く傾斜軸を中心に回転可能なドラムと、ドラムの後部に配置され、表面に洗濯物と接触する突状部を有する回転体と、ドラムと回転体とを互いに異なる回転速度で回転させる二軸駆動形態での動作と、ドラムと回転体とを同じ回転速度で一体的に回転させる一軸駆動形態での動作とが可能な駆動部と、制御部と、を備える。ここで、制御部は、ドラムの内周面に洗濯物が貼り付くことができる貼付き速度までドラムが加速回転するよう二軸駆動形態で駆動部を動作させ、ドラムが貼付き速度まで加速回転する際にドラムおよびドラムに対して相対的に回転する回転体に掛かる回転負荷に基づいて、ドラム内の洗濯物の負荷量を検知する（Ｓ１１、Ｓ１２）。【選択図】図１０
