Abstract: A device for a sanitary tub, for producing a massage stream of air and water has an accommodation device that can be attached at an opening in the tub body of the sanitary tub, for accommodating an electric motor having a drive shaft. A propeller having a hub is attached to the drive shaft, and blades are arranged radially around the hub. A collar is arranged on the accommodation device, positioned within the sanitary tub, having edge-side inflow openings as well as a center outlet opening. The propeller draws in water located in the sanitary tub, through the inflow openings, and subsequently transports it back into the sanitary tub through the outlet opening. The accommodation device has a flow channel for feeding in air, which exits through the outlet opening, through an air channel arranged in the hub and with the stream of water transported by the propeller. Fan vanes for transporting air are arranged within the air channel of the hub.

Abstract: A device for producing a flow of fluid such as water or air in a whirlpool tub, having a rotatable impeller, which aspirates water from the space of the tub via intake openings, and ejects a jet of water or a jet of water and air into the space of the tub via outlet openings. The device further has a drive means for driving the impeller via a drive shaft. The driving means is arranged on the driving axle of the impeller but behind the impeller as viewed within the tub. In addition, the device further comprises a driving means such as a hydromotor, a pneumatic drive or a mechanical drive, that are driven by at least one central power drive, and can be serviced and repaired from within the whirlpool tub.
