The invention discloses a ball barrel type washing machine. The washing machine comprises a washing machine drum, a first rocker, a second rocker, a driving motor, a machine frame, a turnover revolute pair, a swing revolute pair and a motor turnover revolute pair, wherein a through hole is formed in the middle of the first rocker; the first rocker is rotationally connected with the washing machine drum through the turnover revolute pair; a through hole is formed in the middle of the second rocker; and the driving motor is fixed to the through hole of the second rocker and is connected with the washing machine drum through the motor turnover revolute pair. Compared with the prior art, the washing machine has the beneficial effects that clothes in the drum are no longer wound together due to fixed-axis rotation of the drum and the washing effect of the washing machine is improved due to fuller stirring; the rotary center of the driving motor of the washing machine can be perpendicular to the ground when a washing program stops, and the driving motor is positioned under a washing machine drum body and fixedly connected with the machine frame of the washing machine, so that the driving motor can become a driving motor for a dewatering program; and the washing machine is convenient to use and has promotion and application values.
