Abstract
A feeder device for introducing treatment chemicals into a recirculating water stream from a swimming pool. The feeder device includes a housing having a top and bottom portions. A funnel-like hopper having sidewalls and an open bottom forms the inside of the top portion. A grid at least partially closes the open bottom of the hopper. The grid includes a top surface and a bottom surface. One or more chemicals such as chlorine are contained within the sidewalls of the hopper and supported by the top surface of the grid. A dissolving cup having a bottom surface and sidewalls is positioned within the bottom portion. The sidewalls include an opening or notch of a predetermined cross-sectional area formed therein. The bottom surface includes a center nozzle oriented vertically toward the bottom surface of the grid and an off-center nozzle adapted to direct the fluid horizontally in the dissolving cup.
