Pressurized flow self-cleaning whirlpool tub system

摘要

A pressurized-flow self-cleaning whirlpool tub system includes a plurality of water/air jets arranged to introduce air-entrained water jets into a tub basin and a suction outlet from which water in the tub basin is withdrawn. A water distribution circuit is connected to each of the water/air jets for delivering water to each water/air jet. A recirculation pump receives water from the tub basin, pressurizes the water, and delivers the pressurized water to the water distribution system. A cleaning-agent dispenser is provided to receive a cleaning agent in liquid or solid form and mix the cleaning agent with water from the pressurized water supply. In a cleaning mode of operation, a suction valve is closed and the cleaning agent is introduced into the water carrying conduits to effect pressurized cleaning of the water contacting surfaces of the water pathway.
