Abstract
An automatic powdered detergent dispensing system for a dish- or clothes-washer has a valved reservoir (13) delivering powder through a conduit (23), and connected to an air-flow generator with a fan, blower or air aspirator, which is also connected to the conduit to assist powder flow through the conduit. Pref. an ejector (16) with a Venturi tube (21) and chamber (22) is connected to the generator delivery pipe (18) and to an extraction line (17) for removing detergent from the reservoir. The conduit pref. has an elastically biased conical needle valve or flap valve (26) to prevent entry of water vapour or splashes.
