Suction powered pool cleaner |
摘要 |
A pool cleaner is provided of the type powered by a suction or vacuum source, such as by connecting the pool cleaner via a vacuum hose or the like to the suction side of a conventional pool water filtration system. The pool cleaner comprises a compact housing carried on wheels for rolling movement along a submerged pool surface. A debris intake nozzle is formed at a lower end of the housing in close proximity with the pool surface, and communicates through a turbine chamber in the housing to the vacuum hose for water-borne vacuuming of debris from the pool surface. Water draw through the turbine chamber rotatably drives a turbine which in turn powers a drive train to rotatably drive the cleaner wheels together with a downforce fan for improved wheel traction. In addition, the drive train operates at least one timer cam for periodically actuating a reverse clutch assembly to drive at least one of the cleaner wheels in reverse for a brief time interval. The timer cam may also function to open a bypass door venting the turbine chamber to partially relieve the vacuum at the intake nozzle during the reverse drive mode. |
