Title: AUTOMATIC CLEANING WASHER
Abstract:
An automatic cleaning washer comprises an inner barrel (2) and an outer barrel (1). Cleaning particles (4) for cleaning the inner wall of the outer barrel (1) and the outer wall of the inner barrel (2) are disposed in a chamber (3) between the inner barrel (2) and the outer barrel (1). The following one, two or three improved structures are disposed on the inner surface of an outer barrel bottom (5): a sloping area (7) disposed on the inner surface of the outer barrel bottom (5), the area being disposed along a circumferential direction, a position close to a center (8) of the outer barrel bottom being higher than a position close to an outer barrel sidewall (9), and a water discharging opening (6) of the outer barrel bottom (5) being disposed on a lowest position of the outer barrel bottom (5); a ring water passage (12) disposed on the inner surface of the outer barrel bottom (5), adjacent to the outer barrel sidewall (9) and recessed along a circumferential direction, and the water discharging opening (6) of the outer barrel bottom (5) being in communication with the ring water passage (12); and a water blocking convex rib (13) disposed one side facing the water discharging opening (6), of a surface of the outer barrel bottom (5), and disposed on one side of the water discharging opening (6) of the outer barrel bottom (5) along a rotation direction when the inner barrel (2) performs dehydration. The improved structure of the outer barrel bottom (5) of the washer greatly improves the speed and the scouring strength of a water flow, and accordingly, the cleaning particles (4) can be completely discharged.
