Patent ID: 8074476

Claim:
A washing machine comprising: a wash tub for receiving wash water during a washing operation, a rotatably driven cylindrical basket for receiving launderable items for washing supported within said wash tub, a dispenser including a chemical additive chamber having a water inlet for connection to a water supply line and an outlet connected to and communicating with the wash tub, a siphoning device including a siphon cup supported within said chemical additive chamber having a bottom wall, an upstanding siphoning tube supported by and communicating through said bottom wall, and side walls for defining a chemical additive receptacle about said siphoning tube for receiving a predetermined quantity of a chemical additive up to a level below the top of said siphoning tube prior to a wash cycle, said siphon cup having a water inlet in communication with said water inlet, a cover formed with a closed top downwardly opening cylindrical chamber supported in overlying relation to said siphoning tube for defining a siphoning passageway communicating with said receptacle about an underside of said cylindrical chamber, upwardly along an annular passageway between said siphoning tube and cylindrical chamber, and into a top of said siphoning tube such that with siphon cup filled with a predetermined quantity of the chemical additive and the introduction of water into said receptacle from said water inlet the liquid level in said siphon cup will rise above the level of said siphoning tube for causing the simultaneous overflow of liquid from the siphon cup into said chemical additive chamber and the flow of liquid into and through the siphoning tube for simultaneous discharge from said chemical additive chamber outlet to said wash tub, and said siphoning device being formed with a plurality of liquid discharge orifices in communication with said water inlet for directing a plurality of pressurized liquid flow streams across an upper portion of liquid within said siphon cup for further intermixing the water and chemical additive for preventing buildup of the chemical additive on the side wall of the siphon cup.
