Definitions

  • the invention relates to a device for a sanitary tub for generating a water and air existing massage flow with a receiving device which can be fastened to an opening in the tub body of the sanitary tub for receiving an electric motor with a drive shaft, a propeller with a hub fixed to the drive shaft and radially arranged around the hub and wings a arranged on the receiving device, positioned within the sanitary tub rosette with peripheral inlet openings and a central outlet opening, wherein the propeller sucks in the sanitary tub located water through the inlet openings and then conveyed back through the outlet opening in the sanitary tub, wherein the receiving device has a flow channel for supplying air through an arranged in the hub air duct and with the propelled by the water flow exits through the outlet opening.
  • a device with the features described above is known from the document DE 198 34 341 C2.
  • the drive shaft and the hub on an axial bore for the supply of air flow.
  • the supplied air stream mixes within a bell-shaped guide element with the intake via the intake water flow.
  • a Venturi effect is exploited, which consists of an acceleration of the water through the propeller blades and a concomitant local negative pressure in the hub results. Accordingly, the air supply is limited by the extent of the local negative pressure at the propeller hub.
  • the invention has for its object to provide a device with the features described above, which is characterized by an improved supply of ambient air.
  • the air duct fulfills the function of a blower, which leads by the propeller rotation to an increase in the volume of air drawn in from the surroundings.
  • the air duct is preferably annular and concentric with the hub axle.
  • the annular design of the air duct allows a very fine distribution of the sucked air in the sanitary tub supplied water flow.
  • the swirl generated by the fan blades of the air flow contributes to an intensive mixing of air and water.
  • the propeller is designed as a one-piece injection molded part made of plastic, which can be produced with little manufacturing effort.
  • a backflow preventer In front of the air inflow opening of the flow channel, a backflow preventer can be provided, to which an air inlet connection is connected upstream.
  • the air supply is preferably by a connected to a control valve or by a separate knob optionally switched on and off.
  • a guide vane ring is arranged in the outlet opening.
  • the vane ring may have an inner ring with a central passage opening, to which the Guide vanes are formed on the outside.
  • flow guide elements are expediently arranged, which contribute to a rectification of the flow when flowing through the passage opening.
  • the vane ring may be pivotally mounted to the hub axle. This makes it possible to direct the air / water flow in a desired direction when flowing into the bathtub.
  • the vane ring expediently has an annular bearing shell which forms a ball joint with a ball surface segment arranged on the receiving device. At the same time, the vane ring rims against the side of the rosette facing the sanitary sump wall. The pivot position can be changed by pressure on the vane ring, wherein the vane ring remains in the desired position due to its elastic behavior.
  • FIG. 1 and 2 show a device for a sanitary tub 1 for generating a water and air existing massage flow 2 with an opening 3 in the tub body 4 of the sanitary tub 1 attachable receiving device 5 for receiving an electric motor 6 with drive shaft 7, a propeller with a hub 9 fixed to the drive shaft 7 and vanes 10 arranged radially around the hub 9 and a rosette 11 with peripheral inlet openings 12 and a central outlet opening 13 arranged inside the sanitary tub 1.
  • the rosette 11 is in two parts and includes an outer ring 34 with the inflow openings 12 and an inner mounting ring 35 connected to the outer ring 34 with the outlet opening 13.
  • the propeller 8 sucks in the sanitary tub 1 located water through the inlet openings 12 and then conveys the water through the outlet opening 13 in the Sanitary tub 1 back.
  • the receiving device 5 has a flow channel 14 for a supply of air 15, which exits through an arranged in the hub 9 air duct 16 and with the promoted by the propeller 8 water flow 29 through the outlet opening 13.
  • the receiving device 5 is further designed in several parts and has a motor receptacle 32 with the flow channel 14 and an attachable to the tub body 4, connected to the motor mount 32 bearing plate 33. Within the air duct 16 of the hub 9 fan blades 18 are arranged for conveying air.
  • the receiving device 5 also includes a thread 30 for fixing the mounting ring 35 of the rosette 11 and a flow space 31 for guiding the sucked water flow 29.
  • the air channel 16 is annular and concentric with the hub axis X is formed.
  • the propeller is designed as a one-piece injection-molded part made of plastic, which is screwed onto the drive shaft 7.
  • paddle-shaped webs 18 are provided, which at the same time define the distance between the outer and the inner wall of the air channel 16.
  • the bridges 18 go in Flow direction gradually into a purely axial orientation with unbroken surface over.
  • a backflow preventer 20 is provided, to which an air inlet connection 21 is connected upstream.
  • the air supply can be selectively switched on and off by a valve connected to an operating element or a separate rotary knob (not shown).
  • a vane ring 22 is arranged in the outlet opening 13.
  • the vane ring 22 has an inner ring 23 with a central passage opening 24, to which the guide vanes 25 are formed on the outside (see Fig. 4a).
  • flow guide elements 26 are formed, which direct the flow in the passage opening 24 in a direction parallel to the axis Y of the Leitschaufelkranzes 22.
  • a comparative view of Figs. 1 and 2 shows that the vane ring 22 is pivotally mounted to the hub axis X.
  • the vane ring 22 has an annular bearing shell 27 (see FIG. 4b), which forms a ball joint with a ball surface segment 28 arranged on the receiving device 5.
  • the bearing shell 27 is arranged at the outer end of the guide vanes 25.
  • the vane ring 22 is at the same time at the edge of the bathtub wall facing side of the mounting ring 35 at.
  • the pivot position is variable by pressure on the vane ring 22, wherein the vane ring 22 remains in the desired position due to its elastic behavior.
