Definitions

  • the invention relates to a nozzle for introducing a water-air mixture into a tub in accordance with the preamble of claim 1.
  • Nozzles of this type are known in principle.
  • nozzles of the above type have the disadvantage that, although the direction of the jet is adjustable, the mixing ratio between water and air can only be regulated via the amount of air drawn in. While in complex whirlpools the water throughput can be changed by regulating the pump output, this cannot be accomplished in simple designs for cost reasons alone, so that the user is practically dependent on the water passage specified from the pump output and the nozzle dimensions.
  • Another disadvantage of known nozzle construction is that when installed in the tub wall during emptying, the so-called antechamber does not completely empty, so that here the 1 There is a risk of contamination of the residual water.
  • the invention has for its object to improve a nozzle of the type indicated above in such a way that 5 in addition to a cost-effective manufacturing and simpler handling during installation and maintenance and regulation of the water flow is possible.
  • This object is according to the invention with in the characterizing - ⁇ 0 specified drawing part of claim 1. solves ge.
  • the free passage cross section for one medium preferably for the water
  • the free passage cross section for one medium can be changed independently of the pump output. This is not just one. Control of the air supply is possible, which is usually sucked in only because of the Venturi effect via the mouth of the supply line opening into the nozzle and via a change in the suction cross section
  • the valve 30 can be regulated, but also the regulation of the throughput of the other medium, namely the water.
  • the adjustment is provided due to the sealing surfaces so that a complete closure of the antechamber from the tub interior is also possible, so that the
  • 35 relevant tub can also be used for a normal cleaning bath without the water content in the pipe system leading to the pump can run.
  • the center of the spherical surface of the mouth of the feed line for the other medium and the center of the spherical body coincide approximately when the sealing surface is applied. This ensures that the prechamber can be completely closed with respect to the tub interior within the permissible pivoting range of the nozzle body in any angular position.
  • Another preferred embodiment is characterized by the features of claim 3.
  • This embodiment shows an embodiment which is simple in construction and effective in the tight mounting of the spherical body, care being taken to ensure reliable sealing via the supporting and sealing surface of the screw-in adjusting ring and the contact pressure which can be adjusted via the adjusting ring.
  • Antechamber on its lower side is connected to the feed line for one medium, preferably the water. This ensures that the feed system can be completely emptied after use has ended.
  • the feed line for the other medium preferably the air, is connected to the prechamber at an angle from top to bottom. This ensures that only the immediate mouth area of this supply line can run full of water when the pump is shut down.
  • an ornamental and cover ring is provided for the edge of the prechamber spanning the inner tub wall, which is held on the inner wall of the prechamber is.
  • this decorative and cover ring is screw-connected to the prechamber.
  • This ' decorative and cover ring can provide a further additional seal between the interior of the tub and the outside of the tub. If there is a leak during later operation with a built-in tub, there is the possibility of applying a non-visible but effective seal using a suitable cement layer between the decorative and cover ring and the overlapping edge of the antechamber.
  • a further advantageous embodiment of this arrangement is specified in the feature of claim 9.
  • the nozzle consists essentially of a prechamber 1 with an underlying and downward-facing connecting piece 2 for the supply of a first medium, here the water, so that this supply line is connected to a circulation pump.
  • a connecting piece 3 for the supply of the other medium, here the air, which is arranged in such a way that it opens into the antechamber at an angle from top to bottom.
  • an orifice element 4 projecting axially into the prechamber 1 is connected, which in the exemplary embodiment shown is designed as a separate component and is screwed into a corresponding screw attachment 5 on the prechamber 1.
  • the mouth part 4 penetrates practically the entire interior of the prechamber 1 and is provided at its front end with a spherical surface designed as a sealing surface 6.
  • the entire nozzle is inserted from the inside of the tub through an opening in the tub wall 7, the free edge 8 of the prechamber 1 on the tub inner surface 9 overarching.
  • a union nut 10 which can be screwed onto a corresponding threaded attachment 11 on the outside of the prechamber 1, the entire arrangement is clamped tightly and sealed in the opening of the tub wall 7.
  • a nozzle body 13 designed as a spherical body is held in a retaining ring 12 that can be screwed into the prechamber from the inside of the tub.
  • the nozzle body 13 is sealed in the retaining ring 12 by means of a corresponding support and sealing surface 14 on one side and an adjusting ring 15 screwed into the retaining ring 12 with a corresponding support and sealing surface 16, but is freely pivotable to and fro.
  • the nozzle body 13 has within its spherical region a circumferential collar 17 directed against the sealing surface 6 of the mouth part 4, the free edge of which is designed as a corresponding sealing surface with respect to the sealing surface 6 on the mouth part 4.
  • the free cross section between the sealing surface 6 and the sealing surface of the collar 17, which at the same time defines the passage cross section for the water flowing through the prechamber 1, can be changed by rotating the retaining ring 12.
  • the upper half of the nozzle body 13 shows the position with the largest passage cross section, while the lower half shows the position with a small cross section.
  • the arrangement can be dimensioned such that the collar 17 lies completely against the sealing surface 6, so that a complete closure for the water supply is possible.
  • the spherical surface, the spherical part of the nozzle body 13 on the one hand and the sealing surface 6 on the mouth part 4 are like this dimensioned so that they practically coincide in a common center M in the area of the closure position. This ensures that, in particular in the closed position and a setting with only a small flow cross section, the nozzle body 13 can be pivoted perfectly, with a ring cross section of practically the same thickness remaining as the passage cross section. This guarantees perfect jet formation even with reduced throughput.
  • the decorative and cover ring can be formed in one piece.
  • this trim and cover ring is formed in two parts, the outer part 18 'can be made of metal or metallized plastic, which is firmly connected with a separate screw ring 18 ".
  • the retaining ring 12 like the screw ring 18 ′′, is provided on its side facing the tub interior with at least one handle element 19 or 20, which is expediently designed as a key attachment, so that in particular the throughput quantity adjustment by rotating the retaining ring 12 also an appropriate key can be made.

Abstract

Dans un ajutage pour l'introduction, en forme de jet, d'un mélange air-eau dans une cuve avec une préchambre (1) en forme de creuset qui est reliée hermétiquement avec la paroi de la cuve et dans laquelle est maintenu pivotant un corps d'ajutage se présentant sous la forme d'un élément sphérique, ledit corps d'ajutage (13) est monté pivotant dans une bague de support (12). Cette dernière est axialement réglable, de préférence vissable dans la préchambre (1) par rapport à la bouche de la canalisation d'amenée de l'autre milieu. L'alésage du corps d'ajutage (13) est bordé à son extrémité adjacente à la bouche (4) de ladite canalisation, d'une face d'étanchéité annulaire, et la face extérieure de ladite bouche (4) se présente sous la forme d'une face sphérique (6) contre laquelle s'appuie le corps d'ajutage (13) avec la face d'étanchéité de son alésage.
