The barrel bottom 2 has a protrusion 21, and a plurality of protrusions 21 are evenly distributed At the barrel bottom 2, the barrel wall 1 has grooves 11, all of which are parallel to the axis of the barrel body, and the barrel wall 1 is inclined outward at a predetermined angle.

During the washing process, the replaceable inner tub cooperates with the middle tub in the washing machine body, and the middle tub drives it to rotate. When the inner tub rotates, the water and clothes inside also rotate with the inner tub. If the inner tub rotates intermittently or reciprocally, water and Clothes will also change the way of rotation with the inner tub, which will generate agitation and friction, so as to achieve the purpose of washing clothes.

During the washing process of the inner tub, the barrel body in contact with water and clothes is of a sealed structure. During the washing process, the clothes only contact the injected water and the sealed barrel body. The water is located in the inner barrel and will not flow into the inner barrel. Outflow, the laundry process will not be polluted, can avoid cross-infection, and ensure the cleanliness of the washed clothes.

After washing and drying, the middle barrel drives the inner barrel to rotate quickly. Since the inner barrel and the barrel wall 1 of the middle barrel have an outwardly inclined angle, the water in the inner barrel can move upward along the barrel wall 1, from the upper side of the barrel wall 1 throw out.
