Abstract

A dispensing assembly structured to automatically add or dispense cleanser, deodorant, disinfectant and/or like additive to a toilet bowl or urinal, particularly of the type used in commercial applications which are normally connected to a pressurized water supply for flushing without the presence of an accessible flush tank, as is present in most domestic toilet fixtures. The assembly comprising a retention chamber disposed in fluid communication between a pressurized water supply pipe and the toilet bowl or urinal and structured to retain the additive in contact with at least a first portion of the flush water. The outlet of the pressurized water supply pipe is structured to discharge a second portion of the flush water into the retention chamber thereby displacing the first portion of the flush water from the retention chamber into the toilet bowl or urinal and providing the additional water necessary during a flushing operation.

Claims19

Dependent claims

An automatic additive dispensing assembly structured for use with a toilet fixture which is directly connected to a pressurized water supply without a flush tank, said assembly comprising:

an outer container having a hollow interior,
a supply pipe from the pressurized water supply structured to engage said outer container in an interconnected and fluid communicating relation, the supply pipe comprising a longitudinal axis,
a support bushing structured to movably interconnect the supply pipe to said outer container in said fluid communicating relation,
a retention chamber comprising an open upper mouth positioned within said hollow interior of said outer container, said retention chamber disposed in fluid communication with the supply pipe,
a first portion of flush water retained in said retention chamber for a period of time,
an additive retained in said retention chamber in a contacting relationship with said first portion of flush water for said period of time,
a discharge pipe structured to engage said hollow interior of said outer container in an interconnected and fluid communicating relation, the discharge pipe further disposed in fluid communication with an interior of the toilet fixture,
a support flange structured to engage the discharge pipe in an interconnected and supporting relation,
said support bushing and said support flange cooperatively structured to permit rotation of said outer container simultaneously about the supply pipe and the discharge pipe along the longitudinal axis of the supply pipe while disposed in said interconnected and fluid communicating relation with each,
the supply pipe structured to discharge a second portion of flush water into said retention chamber, said second portion of flush water thereby displacing at least said first portion of flush water, said open upper mouth structured to permit at least said first portion of flush water to overflow thereover into said hollow interior of said outer container, and
said hollow interior structured to facilitate discharge of at least said first portion of flush water into the interior of the toilet fixture via the discharge pipe.

An automatic additive dispensing assembly structured for use with a urinal, said assembly comprising:

an outer container having a hollow interior,
a supply pipe from a pressurized water supply structured to engage said outer container in an interconnected and fluid communicating relation, the supply pipe comprising a longitudinal axis,
a support bushing structured to movably interconnect the supply pipe to said outer container in said fluid communicating relation,
a retention chamber positioned within said hollow interior of said outer container, said retention chamber structured to be disposed in fluid communication with the supply pipe,
a first portion of flush water being retained in said retention chamber for a period of time,
an additive retained in said retention chamber in a contacting relationship with said first portion of flush water for said period of time,
said period of time at least partially defined as an amount of time required for said additive to mix into said first portion of flush water such that said first portion of flush water comprises an effective concentration of said additive,
said effective concentration being at least partially defined as a concentration of said additive in said first portion of flush water required for said additive to impart an intended effect to the urinal during the flushing operation,
a discharge pipe structured to engage said hollow interior of said outer container in an interconnected and fluid communicating relation, the discharge pipe disposed in fluid communication with an interior of the urinal,
a support flange structured to engage the discharge pipe in an interconnected and supporting relation,
said support bushing and said support flange cooperatively structured to permit rotation of said outer container simultaneously about the supply pipe and the discharge pipe along the longitudinal axis of the supply pipe while disposed in said interconnected and fluid communicating relation with each,
the supply pipe structured to discharge a second portion of flush water into said retention chamber, said second portion of flush water thereby displacing at least said first portion of flush water into said hollow interior of said outer container,
said hollow interior structured to facilitate discharge of at least said first portion of flush water into the interior of the urinal via the discharge pipe, and
said outer container movably mounted relative to the urinal and selectively disposable between an access position and a stored position.
