Description

a washing machine

technical field

The invention relates to the field of household appliances, in particular to a washing machine provided with a non-porous washing tub.

Background technique

At present, a general washing machine includes an inner barrel and an outer barrel, and many small holes are arranged on the inner barrel wall. When the washing machine is dehydrating, due to the centrifugal force of high-speed operation, the clothes are close to the barrel wall, and the water in the clothes enters the outer barrel through the small holes. The barrel is discharged out of the washing machine to achieve the purpose of dehydration. Because the inner and outer barrels of the washing machine with this structure are connected, during the washing process, the water level of the outer barrel is equal to the water level of the inner barrel, but it does not work. Like this, not only can cause the waste of a large amount of washing water, the dirt and the bacterium in the washing water are also easy to accumulate between the inner tub and the outer tub, and it is not easy to clean, causing secondary pollution of the clothes.

In response to the above problems, we developed a washing machine with a non-porous washing bucket in the early stage. The so-called non-porous washing bucket is essentially that the lower part of the inner bucket of the washing machine has no holes. After water filling, when washing and rinsing, there is only water in the inner tub, and there is no water between the inner tub and the outer tub, so that the water in the washing machine can be fully utilized, and 40% less water is used when filling water than other washing machines. , It can also save detergent. In addition, because the amount of water in the inner tub is reduced, the load of the washing machine is reduced to a certain extent, and it also saves more electricity. During dehydration, the inner tub rotates at a high speed, and the water detached from the clothing flows out of the inner tub through the dehydration drainage hole at the upper end of the inner tub along the inner tub.

The outer wall or inner wall of the inner tub needs to be provided with a drainage assembly, which communicates with the dehydration drain hole to guide the washing water out of the inner tub. In the prior art, a lint filter needs to be installed inside the inner tub, and the lint filter is generally It is connected and fixed on the inner wall of the inner barrel through a connecting piece, and the drainage assembly is fixed on the inner or outer wall of the inner barrel through another connecting piece. Both the lint filter and the drainage assembly need to be connected and fixed on the inner barrel through a connecting piece, so that There are many holes in the inner tub of the washing machine, the connection structure is complex and redundant, and the assembly task is large, which is not conducive to improving production efficiency.

In view of this, the present invention is proposed.
