ABSTRACT:
The improved portable hydrotherapy bath assembly disclosed is designed for mounting on the side wall of a conventional bathtub and includes a motor housing, an overhead support housing and a pump housing. The motor, pump and overhead support housings are made as a single integral unit with their upper ends being closed by a cover. The motor housing is adapted to be disposed without the bathtub, the overhead support housing is adapted to rest on the tub side wall and pump housing is adapted to be disposed within the tub, with its lower end adapted to be immersed within the water in the tub.
A pumping chamber is mounted on the lower end of the pump housing and includes an impeller means whose drive shaft is perpendicular to the longitudinal axis of the pump housing. An electric motor is mounted within the motor housing and is directly operatively connected with a rotary shaft journaled in the overhead support housing. Pulleys are mounted on this rotary shaft and on the drive shaft of the impeller means, and an endless belt operatively connects the pulleys.
The pumping chamber includes horizontally disposed, diametrically oppositely directed first and second discharge ports. A unique rotary valve member is positioned within the pumping chamber for selectively controlling the discharge of water, under pressure, through either the first discharge port or the second discharge port. The rotary valve is actuated by a control knob mounted on the side wall of the pump housing facing away from the side wall of the bathtub. The axes about which the rotary valve and control knob are rotated are coaxial with the longitudinal axis of the drive shaft of the impeller means.
