Filter element in a pool cleaning device

摘要

A filter element (2) for a swimming pool cleaning device which obviates the need to turn the device upside down and for non-return valves to prevent dirt or unfiltered water being returned to the pool has a basket-like shape including a tubular central stem (4) configured to be seated on an exit tube (26) of the cleaning device. The central stem (4) is surrounded by an annular trough (8) constituting the active filtering portion of the element and the outer rim of the trough is detachably affixed to an inner shell (18) of the cleaning device. During operation of the device solids-entraining water drawn in by an impeller (22) of the device enters the annular trough (8) from above and is passed through the active filtering portion and clean water is expelled through the exit tube (26) and returned to the pool. <IMAGE>
