PROBLEM TO BE SOLVED: To provide a washing machine which automatically supplies a proper amount of a detergent and a softening agent supplied to each tank, according to the amount of laundry.SOLUTION: A washing machine includes: a housing (4); a water tub (17) including a rotary drum (20) inside, in the housing; and washing treatment liquid automatic input means (30) for supplying a detergent to the water tub. A DC brush motor is used as a supply motor (65), and a speed reduction ratio to a gear pump (51) is set properly. Thus, in a viscosity range from a softening agent whose viscosity is the smallest to a liquid detergent whose viscosity is the highest, "supply unevenness" which is a difference between the maximum supply amount and the minimum supply amount per unit time is minimized, and substantially a constant supply amount can be supplied irrespective of viscosity.SELECTED DRAWING: Figure 1 【課題】それぞれのタンクに供給された洗剤と柔軟剤とを、洗濯物の量に応じて適量を自動的に供給する洗濯機を提供する。【解決手段】筐体（４）と、筐体内部に回転ドラム（２０）を内部に備えた水槽（１７）と、水槽内に洗剤を供給する洗濯処理液自動投入手段（３０）とを備えた洗濯機において、供給モータ（６５）として直流ブラシモータを用い、ギヤポンプ（５１）までの減速比を適切に設定することにより、粘度の最も小さい柔軟剤から粘度の最も大きい液体洗剤までの粘度範囲において、単位時間あたり最大の供給量と最小の供給量との差である「供給量ばらつき」を最小として、粘度によらず略一定の供給量を供給できる。【選択図】 図１
