Title: Sink mounted water agitation
Inventor: BECKNELL DWAYNE
IPC: B08B3/10
Filed: 1997-05-13
Abstract: Household and institutional sinks are commonly used in cleaning regimens in which articles are contacted with aqueous cleaning media under conditions of agitation. Such agitation can be provided by directing the aqueous medium contained within the sink to a pump that returns the aqueous medium to the sink under agitating conditions such that the agitation can act to promote soil removal. The aqueous medium can be withdrawn from a waste line installed in a sink drain.      The aqueous medium can then pass into pump means which can return the aqueous medium to the sink at a location in the sink causing the aqueous medium to agitate and circulate within the sink bowl. Preferably, valued waste line hardware can be installed in the drain such that when the waste line valve is closed, the aqueous medium is retained in the sink. The pump intake is placed in liquid communication with the aqueous cleaning medium upstream of the valve. The aqueous cleaning medium is drawn by the pump from the waste line and is then directed by the pump returning to an annular return collar formed on the waste line installed in the drain.      The pumped aqueous medium is directed by the return collar into the bowl of the sink assembly. The return collar has stator means creating a horizontal cyclonic circulation pattern.
