ABSTRACT:
A filter for a washing machine is disclosed. The filter includes a filter case attached to an inner lower portion of a dehydrating tub of the washing machine for forming a predetermined space with the dehydrating tub, including an attachment portion for being attached to the dehydrating tub and a filter receiving portion formed with an opening portion, and a pocket type filter including a front panel attached with a mesh net to one side thereof for filtering fluff intermingled in the washing water, a rear panel for forming a predetermined space with the front panel by being coupled to the front panel by means of a hinge shaft to be opened/closed while being attached with a mesh net for filtering the fluff intermingled in the washing water to one side thereof, and a check valve fixed to the lower side of the rear panel for confining the flow of the washing water introduced into the space between the front panel and the rear panel, the pocket type filter being inserted into the filter receiving portion and being made of a transparent material. Since the front panel of the pocket type filter is made of a transparent material and the pocket type filter is revealed without screening by the filter case, it is possible to measure the amount of the fluff accumulated within the pocket type filter without separating the pocket type filter from the filter case.
