Abstract

A compact, portable clothes washer and dryer system requires no direct water connection or drain line and includes a feed reservoir for holding hot or cold water; a basket for receiving clothes and said water from said feed reservoir; a filtration membrane unit that generates permeate for rinsing said clothes and retentate; a motor for operating said basket; a pump for circulating water from said feed reservoir through said membrane unit and to said basket; and a heating assembly for drying said clothes in said basket. The system reduces water usage and gray water generation for washing clothes. The system is particularly useful in dormitories, small apartments, or other remote dwellings where water is scarce or where there are no water feed lines or drains.
