Definitions

  • the invention relates to a drain for a wet room, preferably for a shower, with a drain housing, at which an outlet for connection of a drain pipe is provided, wherein the drain housing is provided with a pump for conveying water in the direction of the outlet, and wherein the pump provided with a hydraulic drive and is formed from a mounted in the drain housing pump impeller.
  • the invention relates to a shower or a wet room with such a flow.
  • Drains for shower trays or shower trays as well as floor drains for barrier-free showers are known in a variety of configurations. These processes must have a relatively high drainage performance. A high drainage performance is especially required in showers equipped with rain showerheads. Such rain showers are popular with many people and are increasingly in demand. However, commercial shower drains are generally limited in their drain performance due to various constraints.
  • a foam-based shower floor element for forming a floor-level shower which includes a drain pot having a water drain, wherein the drain water is conveyed by means of a pump having an electric motor driven pump.
  • the impeller is arranged in the counter to a surrounding bottom surface of the shower floor element sunk arranged drain pot.
  • a mechanism for the promotion of sanitary hot water known.
  • the energy of an existing water supply system is used.
  • the mechanism has two turbine wheels, which are connected to each other via a transmission.
  • the turbine wheel is driven by water, which is already pressurized by the water supply system with a certain pressure.
  • the turbine wheel automatically rotates. This drives the further turbine wheel via the gearbox.
  • the turbine wheel acts as a pump to deliver service water for recycling to a higher energy level.
  • the present invention has for its object to provide a sequence of the type mentioned above, which offers a higher drainage performance than commercial shower drains at a given drain pipe with standard diameter and is optimized with respect to the installation of the pump and the tightness of the drain body.
  • the process according to the invention is characterized in that the hydraulic drive has a drive wheel which can be acted upon by water and which is coupled to the pump impeller via a magnetic coupling.
  • the pump can be at a given outlet pipe inside diameter of z. B. 34 mm or 44 mm drain performance over that of a conventional process that works exclusively on the principle of gravity drainage, significantly increase.
  • the pump of the drain is provided with a hydraulic drive.
  • This allows the use of the energy of the water entering the shower or the wet room to accelerate the running water.
  • no additional control elements are needed.
  • This results in a synergy effect, which uses the energy of incoming water to increase the drainage performance. This effect can be used especially in showers.
  • the higher the volume flow of the incoming water the greater the performance of the pump and the higher the drainage performance of the process according to the invention.
  • the pump according to the invention is formed from a pump impeller mounted in the outlet housing, wherein the hydraulic drive has a drive wheel (impeller) which can be acted upon by water and which is coupled to the pump impeller via a magnetic coupling.
  • a drive wheel impeller
  • This offers advantages with regard to the assembly of the pump and with regard to the tightness of the drain housing. Because to drive the pump impeller no drive shaft is required, which optionally extend from the outside into the drain body and would require a shaft seal. Such seals are relatively expensive.
  • the process according to the invention comes so without a the drain housing penetrating drive shaft. The rotation of the drive wheel is transmitted by the magnetic coupling contactless to the pump impeller. The reliable tightness of the drain housing is thus not affected.
  • the magnetic coupling has the advantage that the pump impeller for cleaning purposes can be easily removed from the drain body. The release of a mechanical shaft connection is not required.
  • the magnetic coupling of pump impeller and drive wheel can be realized in that the drive wheel and the pump impeller are provided with embedded magnets.
  • the drive wheel and the pump impeller can also be made of magnetized plastic.
  • the pump impeller is preferably designed in the manner of the impeller of a centrifugal pump, particularly preferably as a radial or Halbaxialrad a centrifugal pump.
  • a shower drain which is mounted on the drain opening of a (not shown) shower tray or shower tray.
  • the drain 1 comprises a drain housing 2 made of plastic, which is constructed from a pot-like housing part 2.1 and a housing cover 2.2.

  • the sealing ring 4 has on the upper side a circumferential rib profile.
  • the drain housing 2 is fixed by means of a mounting flange 5 at the drain opening of the tub or shower tray.
  • the fastening flange 5 has three holes uniformly distributed over its circumference, into which fastening screws (not shown) are introduced.
  • the mounting holes are in the housing cover 2.2 cast threaded sleeves 7 assigned.
  • a cover 8 is detachably mounted, through which the inlet opening 3 of the drain housing 2 is covered.
  • web-shaped spacers 8.1 are formed, limit the inlet slots, and sleeve-shaped plug elements 8.2, which receive the cylindrical heads of the mounting screws.
  • the heads of the fastening screws (not shown) are each provided with an annular groove and a rubber ring inserted therein (not shown) provided. This results in a frictional connection between the screw heads and the sleeve-shaped plug-in elements 8.2 of the cover. 8
  • the drain housing 2 has an extension 2.3 laterally, which opens into a connecting piece 2.4 as an outlet.
  • a connecting piece 2.4 In the connecting piece 2.4 an arcuate drain pipe (outlet bend) 10 is inserted.
  • the drain pipe 10 carries at its insertion end a conical sealing ring (not shown) and is connected by means of a screwed with the external thread 2.5 of the connecting piece 2.4 union nut 11 liquid-tight with the outlet of the drain housing 2.
  • the drain housing 2 forms a trap.
  • it has a dip tube 12 inserted therein and a partition wall 2.6 arranged between the inlet opening 3 and the outlet 2.4, which extends from the bottom of the cup-shaped housing part 2.1 upwards and defines an overflow edge 2.7.
  • the dip tube 12 is substantially cylindrical and held on an annular shoulder or conical surface 2.8 of the housing cover 2.2. To remove the dip tube 12 this has a transverse to the central axis handle bar 12.1.
  • a closed by a removable plug 13 opening 2.9 is formed, through which a cleaning spiral can be introduced into the outlet pipe (outlet) 2.4 connected drain pipe 10 if necessary after removal of the dip tube 12 and the plug 13.
  • the cleaning opening 2.9 is aligned with the outlet or connecting piece 2.4.
  • the plug 13 is provided with a handle element Provided 13.1, which projects into the pot-like housing part 2.1 and in the direction of the dip tube 12, wherein the dip tube 12 also serves as a stop for the handle element 13.1.
  • the gripping element 13.1 is preferably web-shaped or rib-shaped, protrudes radially with respect to the cylindrical plug 13, and is substantially vertically aligned so as not to hinder the water drainage in the direction of the outlet 2.4 appreciably.
  • the plug 13 is thus secured by its protruding handle element 13.1 and the immersion tube 12 adjacent thereto against moving out of the cleaning opening 2.9 of the partition 2.6.
  • the pump consists of a pump impeller (impeller) 14 mounted in the drain housing 2 and is driven by a hydraulic drive (hydraulic drive) 15.
  • the hydraulic drive 15 consists of a drive wheel (outer paddle wheel) 15.1, which is arranged in a housing 15.3 having an annular channel 15.2.
  • the housing 15.3 has an inlet connection 15.4 and an outlet connection 15.5.
  • the nozzles 15.4, 15.5 are provided with union nuts 16 for liquid-tight connection of a (not shown) water supply line or a shower head continuing water supply line (not shown).
  • the nozzles 15.4, 15.5 are integrally formed on the housing 15.3 in such a way that the drive wheel 15.1 is acted upon substantially axially by water supplied via the nozzle 15.4.
  • the inlet 15.4 associated with the inlet opening and the nozzle 15.5 associated with the outlet opening of the housing 15.3 are offset from each other and arranged on opposite sides of the housing.
  • the inlet opening 15.13 is located in the Bottom of the housing 15.3, while the outlet opening is formed in the top of the housing 15.3.
  • the upper side of the drive housing 15.3 has a recess 15.6 defined by the annular channel 15.2, into which the bottom section of the pot-like housing part 2.1 of the drain housing 2 is inserted.
  • the underside of the drive housing 15.3 is sealed liquid-tight after insertion of the drive wheel 15.1 by a plate-shaped bottom 15.7.
  • the bottom 15.7 has on its inside an annular elevation 15.8, which serves as the drive wheel 15.1 as a sliding surface.
  • the upper part of the housing 15.3 at the bottom of the recess 15.6 has a downwardly projecting, annular or circular-shaped projection 15.9, which serves as an axis for the hub of the drive wheel 15.1.
  • the blades 15.10 of the drive wheel 15.1 are connected to an inner circular-cylindrical wheel section 15.11 and an outer circular-cylindrical wheel section 15.12 of the drive wheel.
