Automatic pool chlorinator

Abstract

A swimming pool chlorinator has a flow pipe that is removably attached to the inlet jet pipe from the pool circulation system and a container for chlorine-containing tablets that is located above the flow pipe. The chlorinator is submerged and the container has an opening to allow water from the pool to flow into the container and dissolve the tablets. A duct from the bottom of the container leads to the interior of the flow pipe. The duct extends into the flow pipe to constrict the flow through the pipe, so that this flow causes chlorinated solution to be aspirated from the container into the flow by means of the Venturi effect. The container is transparent so that the chlorine tablets are visible from outside the container. The container further has a removable lid for refilling the container. The container opening comprises a slotted hole in the lid, with a sliding plate that can be moved over this slot to vary the size of the opening and thereby regulate the flow through the container. The flow pipe has a knurled end that is inserted in the inlet jet pipe, so that the inlet jet pipe supports the chlorinator and the entire assembly may be removed from the pool for refilling.
