Air excitation hydromassage system

Abstract

An air excitation bath system designed to produce a hydromassage effect in, for example, an ordinary bathtub. The system utilizes an air control serial array of adjustable nozzle assemblies preferably installed on the bottom of the tub to provide the user with means for adjusting the rate and direction of the air flow through the water to massage different parts of the body. The air control system is characterized by at least one and preferably two or more serial arrays of adjustable nozzle assemblies. Each such array is serially interconnected by a plurality of flexible hoses. The respective arrays are interconnected, preferably to a common flexible hose which is in turn connected to an air blower through at least one safety loop and a check valve. Each nozzle assembly is provided with a cap, a body and a foot as well as an additional check valve located between the cap and the body. The cap and the body are specially configured to permit adjustability of air flow from either substantially off to substantially full flow and also provide means for directing air flow laterally along the surface of the floor of the tub and/or vertically toward the top surface of the water. An especially novel feature of the present invention is the design of a nozzle foot which is positioned beneath the tub floor and is provided with a unique low profile configuration to substantially minimize the space required beneath the tub.
