  • Apparatus for dispensing rinse water additive in an automatic washing machine
    Patent number: 6681963
    Abstract: A rinse water additive dispenser for use in an automatic washing machine is disclosed. The dispenser includes a top, a valve assembly and a base releasably connected to the top. The valve assembly is retained within a valve housing located in the top and is able to move within the housing. The valve assembly includes a resilient disk valve and counterweight that are interconnected by a valve post. The resilient valve is located, enclosed, or compressed between the top and base portions when the top and base are connected. The top and base can be connected with threads, tongue and groove structures etc. When subjected to the centrifugal force of a spin cycle, the movement of the counterweight within the device causes the resilient disk to unseat from between the top and base allowing fluid communication between the dispenser and the tub of the washing machine. Optionally, the dispenser can have an elliptical cross section to promote proper orientation of the dispenser during the spin and rinse cycles.
