ABSTRACT:
An apparatus is provided which enables a container of cleaning fluid to lie in a water closet and dispense cleaning fluid solely into the toilet bowl rather than into the water closet. The apparatus includes a storage chamber (54) for holding granules of a chemical that dissolves in water to create cleaning fluid, and a transfer chamber (64) through which water flows from a refill valve outlet (40) into a standpipe (44) that leads to the toilet bowl, at each flushing of the toilet. The transfer chamber is coupled to the storage chamber so that cleaning fluid can migrate from the storage chamber (54) into the transfer chamber (64), and yet during each flushing the water from the refill outlet primarily sweeps out cleaning fluid in the transfer chamber. An anti-siphon device (74) between the refill valve outlet and the cleaning fluid dispensing apparatus includes a check valve, and a chamber that surrounds the check valve. The anti-siphon chamber has air holes that let water in the anti-siphon chamber drain into the transfer chamber when water is no longer supplied from the refill outlet, the holes being blocked during flow from the refill outlet.
