Referring to fig. 1-2, the improved drum washing machine of the present invention comprises: a cabinet 100, an outer tub 200, and an inner tub 300.

A mounting cavity 101 is defined in the casing 100 for assembling various components;

the outer barrel 200 is fixedly arranged in the mounting cavity 101, and a water storage cavity 201 is defined inside the outer barrel;

the inner tub 300 is rotatably installed in the outer tub 200, and defines a washing chamber 301 therein.

Referring to fig. 3 to 5, the inner tub 300 is supported and installed in the outer tub 200 by a horizontal rotation shaft 400, and the inner tub 300 is driven by a driving unit 500 to rotate around the horizontal rotation shaft 400 to perform a washing operation.

Specifically, the water storage cavity 201 of the housing 200 is used for storing water, a water filling port 202 and a water discharge port 203 are formed in communication with the water storage cavity 201, the water discharge port 203 is disposed at the bottom of the casing 100, and the water filling port 202 may be disposed at the bottom or on a side wall.

The inner barrel 300 has a cylindrical shape, and has a circumferential surface 310 and end caps 320 provided at both ends of the circumferential surface 310. The inner tub 300 is horizontally installed in the water storage chamber 201, the horizontal rotation shaft 400 is connected to the both end caps 320, and the inner tub 300 is driven by the driving device 500 to rotate around the horizontal rotation shaft 400 to perform a washing operation.

The inner tub 300 is installed in the water storage chamber 201 and forms a gap with the inner wall of the water storage chamber 201, so that the inner tub 300 can rotate.

The inner barrel 300 may be made of a plastic material or a metal material.

When the barrel is made of plastic, the circumferential surface 310 and the end cap 320 may be formed by integral injection molding or may be of a split structure, as long as a cylindrical barrel body can be formed.

The center of the end cap 320 may be formed with a protruding shaft connection portion 322 protruding outward, and the center of the protruding shaft connection portion 322 is provided with an insertion hole 321.

The protruding shaft connecting part 322 is provided to reinforce the contact with the horizontal rotation shaft 400 and improve the supporting force therebetween; the horizontal rotation shaft 400 is fixed in the insertion hole 321, and the horizontal rotation shaft 400 rotates to drive the inner barrel 300 to rotate.

One end of the horizontal rotating shaft 400 is connected to the end cap 320, the other end is supported on the barrel wall of the water storage cavity 201, and a bearing 210 is arranged at the joint of the horizontal rotating shaft 400 and the barrel wall.

The bearing 210 is provided to reduce friction during rotation.

A sealing ring should be added at the joint between the horizontal rotating shaft 400 and the tub wall to prevent water seepage.
