Problems solved by technology
[0013] Although the balance ring can effectively reduce the influence of eccentric loads, the liquid balance ring has a large volume and takes up a large capacity space, and the manufacturing cost of the steel ball balance ring is relatively high. The washing machine only uses the balance ring

Embodiment Construction
[0030] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0031] Such as image 3 As shown, the present invention includes a drum body 1. Three lifting ribs 2 are evenly arranged in the drum body 1. The inner cavity of the lifting ribs 2 is a sealed cavity. The radius is provided with a through hole and communicated with each other through the connecting pipe 3, and the air return hole is provided at the minimum turning radius of the three lifting ribs 2 relative to the drum body 1 and communicated with each other through the return pipe 4. The cavity is filled with saturated brine accounting for 50% of the volume of the cavity, and usually each lifting rib 2 is filled with saturated brine accounting for 40% to 60% of the volume of the cavity.
[0032] If necessary, the sealing chamber of the lifting rib 2 is radially separated into at least two layers of independent sealing c...

The invention relates to a drum of a drum washing machine, which comprises a drum body, wherein at least three lifting tendons are evenly arranged in the drum body. The drum of a drum washing machine is characterized in that the inner cavity of each lifting tendon is a sealed cavity body; the maximum turning radius of each lifting tendon relative to the drum body is provided with through holes which are mutually communicated by communication pipes; the minimum turning radius of each lifting tendon relative to the drum body is provided with air return holes which are mutually communicated by air return pipes; and each lifting tendon is filled with saturated salt water which occupies 40-60% of volume of the inner cavity. In the drum of a drum washing machine, the inner cavities of the lifting tendons of the drum serve as sealing cavity bodies which are mutually communicated and filled with the saturated salt water. Under the condition that the washing volume of the washing machine is not reduced, the balance force of eccentric load for dewatering is provided for the drum washing machine, no space is occupied, and manufacture cost is low. The purpose that the drum washing machine has the advantages of low vibration, low noise and low cost is realized.
Description
technical field [0001] The invention relates to a drum washing machine, in particular to a drum of a drum washing machine. Background technique [0002] During the dehydration process of the drum washing machine, the unbalanced distribution of the laundry load and the high-speed rotation of the drum will cause the washing tub to be excited by the eccentric load. This excitation can cause severe vibration of the whole machine. This vibration of the whole machine is not only It produces a lot of noise and has an impact on the life of the washing machine's mechanical and electrical components. Therefore, controlling the vibration of the washing machine has an important influence on the performance of the washing machine. [0003] Because the rotation axis of the drum washing machine is horizontal (or the rotation axis is at an angle of less than 30° to the horizontal), the clothes are always distributed on the lower half of the drum under the action of gravity before entering ...
