Description

Double-drum washing machine

Technical Field

The present invention relates to a washing machine, and more particularly, to a twin drum washing machine.

Background

With the social development and the continuous improvement of the living quality requirements of people, the double-roller clothes treatment device is in line with the development and the requirements of the times, not only can save the placing space of the clothes treatment device, but also provides more convenient clothes treatment requirements for users.

One of the important technical problems of the dual drum laundry treating apparatus is how to arrange the dual drum. The former conventional method is to arrange two rollers in respective frames, but a gap exists between the two rollers, which not only occupies more space, but also has larger vibration noise in the using process.

Later, the technology improves the method, two rollers are connected, the space for treating clothes by the two rollers is relatively reduced, the noise is reduced to a certain extent, but a balance adjusting device comprising a balancing weight needs to be additionally arranged on the outer barrel, the cost of the washing machine is increased, and the damping and noise reducing effects are not obvious. And the elements for connecting the double-roller are independently arranged, so that the installation is complicated, the problems of falling and the like caused by the vibration influence of the long-term running process of double-roller clothes treatment are easily caused, and the stability is poor.

In addition, because the inner barrel and the outer barrel are mutually sleeved, dirt is easily accumulated between the inner barrel and the outer barrel in the use process of the washing machine; meanwhile, because the inner drum and the outer drum are mutually sleeved, a user cannot clean the outer wall of the inner drum and the inner wall of the outer drum, so that bacteria in the washing machine are increased, and the washing efficiency of the washing machine and the cleanliness of washed clothes are reduced. Meanwhile, in the washing process of the washing machine, the clothes are beaten and washed through the rotation of the inner barrel, so that the washing capacity of the washing machine is based on the inner barrel, the utilization rate of the inner space of the washing machine is low, and the washing capacity of the washing machine cannot be expanded on the existing basis. If such laundry is left for a long time, dirt will adhere to the laundry, resulting in a problem that the dirt cannot be completely removed.

The present invention has been made in view of this situation.
