Benefits of technology

This patent describes a washing machine that can protect its water seal from foreign substances and prevent damage to its inner parts. The washing machine prevents debris from getting stuck in the water seal and ensures that it is not accumulated there. This results in improved efficiency and durability of the washing machine. The water seal is protected by a clutch that prevents harmful substances from getting inside and damaging the seal and the bearing. Overall, this patent aims to provide a washing machine that can protect and maintain the quality of its water seal.

Problems solved by technology

However, foreign substance and moisture generated during a washing operation in the rotary tub are introduced into the inside the water seal and the sealing is destroyed.
In addition, the moisture is infiltrated into a bearing to rust the bearing, causing a noise during a spin dry operation.
