As shown in fig. 1 to 7, the present embodiment describes a washing machine including: the shell 2 is internally provided with an inner barrel 1, and the axis of the inner barrel 1 is vertically arranged; the top end opening of the inner barrel 1 is provided with an inner barrel opening 101, the bottom end is provided with an inner barrel bottom 103 in a sealing way, and the inner barrel opening is connected with the inner barrel bottom through an inner barrel side wall 102; at least the middle lower part of the inner barrel 1 is not provided with a through hole, so that the inner barrel 1 forms a water container with an open top. Meanwhile, a door cover 4 which can be opened outwards is installed at the upper end of the washing machine shell 2, so that clothes can be put into the inner barrel 1 from the inner barrel opening 101 after the door cover 4 is opened. The lower part of the inner tub 1 is arranged in the washing machine shell 2 through an inner tub support 3, the inner tub support 3 and the inner tub 1 are coaxially arranged, and the inner tub support 3 is connected with the washing machine shell 2 through a damping suspender or a damping support leg so as to realize the purpose that the inner tub support 3 can vibrate and be arranged in the washing machine shell 2; meanwhile, the center of the inner tub bottom 103 is coaxially arranged with the motor shaft of the driving motor 5 of the washing machine to drive the inner tub 1 to rotate, and the inner tub 1 and the driving motor 5 are fixedly mounted on the inner tub support 3. Preferably, the inner barrel bottom 103 and the driving motor 5 are respectively arranged on the upper side and the lower side of the inner barrel support member 3, the driving motor 5 is fixedly connected with the inner barrel support member 3, a motor shaft of the driving motor 5 passes through the inner barrel support member 3 through a bearing and is coaxially and fixedly connected with the inner barrel bottom 103, and a motor shaft of the driving motor 5 can rotate relative to the inner barrel support member 3, so that the purposes that the inner barrel 1 and the driving motor 5 are arranged on the inner barrel support member 3 and the inner barrel 1 can independently rotate under the action of the driving motor 5 to wash internal clothes are realized.

The inner tub 1 is provided with a relatively rotatable stirring structure, and the stirring structure may be any conventional device, for example: pulsator 10, stirring column, and the like. Therefore, under the action of the driving motor, the inner barrel 1 and/or the stirring structure are/is driven to rotate, so that various water flows are formed in the inner barrel, and clothes in the inner barrel are treated by the water flows.
