Description

Washing inner cylinder of washing machine and washing machine having the same

The present invention relates to a washing machine, and more particularly to a washing inner cylinder of a washing machine using a polymer adsorbing material to participate in washing and a washing machine having the same, belonging to the technical field of washing machines.

Background technique

The washing method of the conventional washing machine uses water as a washing medium, adds water and detergent to the washing machine, washes, and then uses the dehydrating function to discharge the sewage in the washing machine, and then re-adds clean water to continue the washing or rinsing process. After the washing is completed, the water is drained. This method simply drains the water and refills the clean wash water. The water consumption is very large. At the same time, the washing liquid contains more environmentally harmful chemicals, and each washing process takes a long time and consumes a large amount of electricity.

In view of the deficiencies of the conventional washing machine, a washing method using a solid particle specially made of a polymer material as a washing medium has appeared in the prior art, and the dirt on the clothes is absorbed and absorbed by the friction between the solid particles and the clothes, thereby realizing Washing function.
