Definitions

  • the invention relates to a single jet nozzle, which is used to irradiate air into a water basin.
  • the water basin is preferably designed as a whirlpool.
  • Such jet nozzles are known in many forms.
  • the invention is based on a single-jet nozzle, such as that described in GB A 2114021; EP 209646 and DE 3040617 DE 238865 KPA, GM 89 01 137.6.
  • jet nozzles have the disadvantage that the jet air is emitted at the mouth of the nozzle in the form of small compressed air bubbles. Disadvantageously, small air bubbles released to the water do not generate turbulence for underwater massage.
  • nozzle mouth closures of known single-jet nozzles have the disadvantage that either compressed air is discharged directly at the nozzle mouth or, in the case of closure bodies arranged upstream, that water residues in the Nozzle housings remain and there is a risk of bacteriological contamination.
  • the object of the invention is to improve the mode of operation and function of these known jet nozzles. This task is solved by the characteristic features of the main claim.
  • the embodiment of the jet nozzle according to the invention with the features of claim 1 has the advantage that large-volume and largely decompressed air bubbles are released to the water and consequently strong turbulence and effective underwater massage is generated.
  • the release of air bubbles that decompress before leaving the nozzle mouth has the advantage that cold zones in the vicinity of the jet mouth are avoided.
  • Moving the decompression chamber upstream has the advantage that the jet air can absorb thermal energy even before it exits the jet mouth and the temperature of the jet medium consequently increases.
  • the drainage level has the advantage that the decompression chamber can be emptied of residual water and bacteriological contamination by residual water is avoided.
  • the embodiment with the features of claim 2 has the advantage that the decompression chamber is horizontal and widens radially, that the drainage outlet opens into the water basin.
  • the embodiment with the features of claim 3 has the advantage that the decompression chamber can be connected to a central drainage system.
  • the embodiment with the features of claim 4 has the advantage that the incident air downstream is opposed by an increasingly larger volume and increasing expansion space.
  • the embodiment with the features of claim 5 has the advantage that cold zones are avoided at the nozzle mouth.
  • the embodiment with the features of claim 6 has the advantage that the jet air blows into the water basin essentially decompressed.
  • the embodiment with the features of claim 7 has the advantage that the input mouth closing spring is accessible for revision purposes.
  • the embodiment with the features of claim 8 has the advantage that the decompression room is accessible for cleaning purposes.
  • the embodiment with the features of claim 9 has the advantage that large air flow pressure predominates within the narrow cross section, that consequently water backflow is blown out into the supply line, that the jet air downstream of the increasingly larger decompression space is available, which is advantageous in the area of the narrow cross section a the closure body and / or the air supply encircling the residual water drain valve can be used.
  • the embodiment with the features of claim 10 has the advantage that the decompression chamber is covered in a protective manner and the outlet slot is formed with an annular gap surrounding the decompression chamber.
  • the embodiment with the features of claim 11 has the advantage that the cover is designed as a perforated plate.
  • the embodiment with the features of claim 12 has the advantage that the air inlet and the residual water outlet, each provided with valves, can be used in a compact design in the recess provided, that consequently an inexpensive small unit can be used that all components from the inside of the pool are interchangeable.
  • the embodiment with the features of claim 13 has the advantage that the pressure seal opens the drain at low hydrostatic pressure and closes the drain towards the channel at higher pressure.
  • the invention has the advantage over known single-jet nozzles that, with a small number of single-jet nozzles, creates great turbulence in the water, that a less powerful compressed air generator can be used, and consequently the flow noise and energy consumption are reduced.
  • Fig. 1 shows a single jet nozzle 1 with a pot-like nozzle housing 2, the interior of which is designed as a cavity.
  • the cavity serves as a decompression chamber 6.
  • the arrow mark shows the direction of flow of the irradiation medium.
  • the interior of the nozzle housing is in flow connection with an air supply line (not shown) and a compressed air generator.
  • the decompression chamber preferably merges into a radial flange collar F, which lies against the pool wall and achieves sealing by tightening.
  • a web 16 which is arranged within the decompression space and is provided with an internal thread 17, preferably serves as the fastening means.
  • Fastening devices of this type are known from the sanitary field, for example with a chalice plate
  • the cover spanning the decompression space is designed radially to form a medium outlet slot between the basin wall 18 and its circumferential line 21. It is conceivable to arrange spacer feet, the height of which determine the free outlet cross section between the pool floor and the side of the cover facing away from the inner pool.
  • the outlet slot is preferably designed as an annular nozzle.
  • the cover of the decompression chamber is equipped as a perforated plate with a large number of bores. Both the free cross section of the outlet slots and the bores are essentially adapted to the cross section of the decompression chamber.
  • the inlet mouth 3 leading into the interior of the decompression chamber is equipped with the closure body 5 and, in its extension, preferably leads into the decompression chamber 6 with a bottle-neck-like extension FH, and is increasingly formed downstream of the radiation opening 4 with an enlarged cross section and essentially corresponds to that Funnel shape.
  • a cylindrical decompression chamber it is also conceivable to design a cylindrical decompression chamber.
  • a plane 7 is arranged near the closure body 5, which opens into a tubular outlet connector 15.
  • the drain port 15 can be closed by a valve 22, wherein preferably a controllable valve, such as a solenoid valve that can be actuated by electrical energy or a float valve that can be actuated by the drain flow or a ball or flap valve that can be actuated by the irradiation medium, is preferably switched into the drain line.
  • a controllable valve such as a solenoid valve that can be actuated by electrical energy or a float valve that can be actuated by the drain flow or a ball or flap valve that can be actuated by the irradiation medium, is preferably switched into the drain line.
  • Fig. 2 shows another variant of the object of the invention.
  • the hollow cylindrical neck of the nozzle housing reaches through the mounting hole and merges radially into the collar flange F.
  • the collar flange is arranged on the inside of the pool.
  • the nozzle housing has an external thread and is clamped to the pool wall (floor) with a lock nut.
  • the flange collar is preferably designed as an inclined plane and opens with its lower edge region into the interior of the water basin
  • the inclined plane runs from the radially outside to the center inside with a gradient of 0.5 degrees.
  • the closure body 5 is arranged centrally.
  • the decompression chamber runs from the center inside to the radially outside and increasingly forms an enlarged outlet cross section Q 2 in the direction radially outside compared to the center inside.
  • the side of the cover facing away from the interior of the water basin is conical, the free distance between the flange collar and the cover increasing in height from the center inside to the radially outside, and the outlet cross section Q 2, preferably in the form of an annular nozzle, having a height of at least one Is 0.5 mm.
  • the funnel-shaped decompression chamber 6 is formed as a depression directly into the bottom of the water basin. According to the invention, it is proposed to design such a depression in the pressing or deep-drawing process in the manufacture of the water basin and to form it on the basin body.
  • the closure body and the inlet mouth 3 are preferably arranged in the center of such a depression.
