Abstract

Automatic powdered detergent dispensing and metering system for washing machines, in particular dishwashing and clothes washing machines, comprising a reservoir (13) adapted to hold the powdered detergent (11), whose addition into the washing tank or tub (24; 681) of said machines occurs through a flow of air generated by pneumatic generator means (14, 46; 14) of a per sè known type. The system comprises actuation means (16; 85) that may be embodied in a number of different ways, described in the patent specification, for determining the conveyance of the powdered detergent into the washing tank or tub (24; 681) when said pneumatic generator means (14, 46; 14) are operating. <IMAGE>
