Abstract: The problem on fast thawing of washing powder in automatic washing machines had been a big problem for long. To resolve the problem ,our research team developed a new kind of fast thawing system, including a dispenser and a powder case. By means of the innovation on the mechanism of fast thawing and the structural designing, we created a new kind of fast thrawing system, which was very different from the existing ones. The new system conduced to marked improvements on the capability of fast thrawing. Furthermore, much more bubbles were produced during water inletting, which could raise the cleaning rate.

Key words: Automatic washing machine, Washing powder, Fast thawing
