The invention provides a washing machine. The washing machine comprises an outer barrel, an inner barrel, a filtering part, wherein the inner barrel and the filtering part are arranged in the outer barrel, and the filtering part is arranged at the bottom of the inner barrel; a collecting part is formed in the filtering part and is a concaved groove. In this way, in the provided technical scheme, by arranging the filtering part at the bottom of the inner barrel, it is avoided that the filtering part occupies storage space of the inner barrel, and clothes are prevented from being worn; by arranging the collecting part in the filtering part, when water flows flow back into the inner barrel through the collecting part, more thread chips and other impurities can be filtered away and stored.
