Abstract
A washing apparatus such as an automatic laundry washing machine includes a wash agent dispenser drawer including an additive compartment for storing various additives such as detergent, bleach and fabric softener. One or more water inflow tubes may extend downwardly into the additive compartment and may be configured to deliver water for diluting the additives contained in the compartment. The inflow tubes are of sufficient length to reach a sub-surface portion of additive held in the compartment. Water may simultaneously be delivered to the surface of the additive. Furthermore, inflow tubes have their outlets positioned adjacent to the base(s) of one or more siphon post/cap assemblies located in the additive compartments, such that a churning effect is produced from the injection of water through the tubes and the siphoning action of the siphon post, whereby mixing is enhanced and additive buildup may be avoided and/or removed.
