The rotating shaft 230 is disposed at the outer side of the washing tub 200 and is fixedly connected with the bottom wall 210 of the washing tub 200, and a driving device may be further disposed in the casing 100, where the driving device may include, for example, a driving motor, a belt transmission member, and a belt pulley, and two ends of the belt transmission member are respectively connected with an output shaft of the driving motor and the belt pulley, and the rotating shaft 230 is fixedly connected with the belt pulley, so that the rotating shaft 230 can rotate together when the belt pulley rotates, and further the washing tub 200 fixedly connected with the rotating shaft 230 is driven to rotate. The rotation shaft 230 is internally penetrated with a transverse pipe 240, and the transverse pipe 240 is communicated with the inside of the washing tub 200, thereby facilitating the running water to enter the washing tub 200 or facilitating the discharge of the washing water in the washing tub 200.

The drum 200 is further provided with a drum door 250 corresponding to the machine door 110, the drum door 250 is communicated with the inside of the drum 200, the drum door 250 may be mounted on the drum 200 in a hinged connection manner, and the drum door 250 is sealed with the drum 200 during washing, thereby preventing wash water from being sprayed.

Alternatively, the cross-sectional area of the drum 200 of the present embodiment gradually increases from the drum door 250 toward the bottom wall 210. That is, the diameter of the washing tub 200 of the present embodiment is larger at the side near the bottom wall 210 than at the side near the tub door 250; the side wall 220 may also be provided with a plurality of water guide grooves so as to guide the washing water to one side of the bottom wall 210 when the tub 200 rotates.
