    Abstract: A washing machine includes a tub containing water, a drum rotatably provided in the tub to accommodate laundry, and a detergent mixing device configured to mix additives supplied into the tub. The detergent mixing device includes a pair of additive cartridges containing a liquid additive and a peristaltic pump configured to selectively supply the additive discharged from the pair of additive cartridges to the tub. The peristaltic pump includes a first path switching motor, a first tub, a second tube, a first rotor and a second rotor rotated by the flow path switching motor, a first rotary bearing permitting a rotation of the first rotor in a first direction and restricting a rotation of the first rotor in a second direction, and a second rotary bearing permitting a rotation of the second rotor in the second direction and restricting a rotation of the second rotor in the first direction.
