The invention discloses an assembly structure of a water discharging device. The water discharging device and a cylinder body are involved, a water inlet and a water outlet are formed in the water discharging device, a fixed frame is arranged at the bottom of the cylinder body and detachably connected with the fixed frame, the water inlet of the water discharging device is fixedly connected with the bottom of the cylinder body, and therefore water in the cylinder body is completely discharged out of the water outlet of the water discharging device. The invention further discloses a washing machine. The washing machine comprises a shell body and the cylinder body, the cylinder body is arranged in the shell body and rotates in the shell body, and the bottom of the cylinder body is provided with the above water discharging device. The installation mode is provided that the water discharging device is fixedly hung at the cylinder component, the phenomenon of residual washing water in the water discharging device is effectively avoided, and therefore the problems are solved that after long time use of the cylinder washing machine, the inside of the whole cylinder of the washing machinegenerates an unpleasant odour and goes mouldy.
