Definitions

  • the invention relates to a whirlpool tub with a piping system and water jet nozzle, with a housing arranged in the tub wall, to which a pressurized water line and an air supply line are connected, with a nozzle body which opens into a jet outlet opening with a nozzle channel and is adjustable in order to change the direction of the jet outlet Position is adjustable, in which the jet outlet opening is lower than a water inlet opening of the nozzle channel, the water inlet opening opening into a water supply channel of an end wall of the nozzle body and an air inlet opening of the nozzle body being in flow connection with the air supply line.
  • a whirlpool tub according to the preamble of claim 1 is known from US-A-4 542 854.
  • the nozzle body can only be adjusted together with a spherical element. Residual water remains in all positions of the nozzle body in any case in the chamber surrounding the nozzle tube, because this widens conically inwards.
  • the air and water guidance are designed in such a way that air or water or a water / air mixture can be blasted into the inner basin.
  • the channels and lines for the water and air supply are arranged so that they empty completely after use. Penetration of soap residues or bath water into the feed system should be prevented by the water and Air outlet nozzle check valves are assigned that are only open during massage operation.
  • the object of the present invention is to develop a whirlpool tub with a water jet nozzle of the type mentioned at the outset such that the water jet nozzle can be emptied automatically when the bath water is drained from the whirlpool tub after it has been used.
  • a whirlpool tub of the type mentioned at the outset in that the nozzle body is adjustable into an outflow position in which the water inlet opening is higher than the pressurized water line and the air inlet opening is located on the upper periphery of the nozzle body.
  • bath water when the whirlpool tub is not in use, only remains in those areas of the pipeline system which include the pressurized water line, to which the cleaning agents and / or disinfectants added to the pipeline system also reach.
  • the special arrangement of the jet outlet opening, water inlet opening and pressurized water line in relation to one another ensures that when the bath water is drained from the whirlpool bath, its use, all residual water can flow out of the water jet nozzle.
  • a particularly simple constructive realization of the inventive concept is achieved when the nozzle body is rotatably mounted in the housing about an axis of rotation and the Exit axis of the nozzle channel at an angle to the axis of rotation, ie obliquely to the horizontal. In this way it is ensured that by simply rotating the nozzle body, it can always be brought into a rotational position in which the residual water flows out of the water jet nozzle completely. If the axis of rotation of the nozzle body is not horizontal, the outlet axis of the nozzle channel must in any case be arranged so that it runs obliquely to the horizontal in order to always ensure that the residual water runs out.
  • the water inlet opening of the nozzle body is preferably arranged eccentrically to the axis of rotation in the nozzle body, so that by rotating the nozzle body from its uppermost position, in which the outlet axis of the nozzle channel has the greatest possible inclination with respect to the horizontal and the water inlet opening also has the greatest possible distance from the pressurized water line Can be rotated position in which the water inlet opening is closer to the pressurized water line, that is, lower.
  • the water inlet opening is in flow connection with the pressurized water line in every rotational position of the nozzle body. This ensures that the jet exit direction can be adjusted over a large angular range by changing the position of the nozzle body during whirlpool operation.
  • the guide sleeve can have a water passage opening on the end face, which is on the one hand in flow connection with the pressurized water line and on the other hand in every rotational position of the nozzle body with its water inlet opening. This can be ensured in a simple manner in that practically the entire bottom wall of the guide sleeve is penetrated by the water passage opening and the pressurized water line is connected to the housing, which receives the guide sleeve, via a nozzle covering the entire water passage opening. As long as the water inlet opening of the nozzle body is above the horizontal central plane of the guide sleeve arranged with the horizontal axis of rotation, residual water is guaranteed to flow out of the nozzle channel after use of the whirlpool tub.
  • the nozzle channel has a straight outlet axis over its entire length and the jet outlet opening is located eccentrically to the axis of rotation of the nozzle body. This ensures that in the outflow rotational position of the nozzle body, the water inlet opening and the jet outlet opening of the nozzle body have the greatest possible height difference, the outlet axis of the nozzle channel running straight to ensure the strongest possible water outlet jet.
  • the flow of the bathing water in the nozzle area and the drainage of residual water is further improved if the water supply channel is coaxial with the outlet axis of the nozzle channel.
  • the water supply channel at least in the discharge rotational position of the nozzle body, runs obliquely to the horizontal, so that no residual water can remain in the water supply channel when the whirlpool device is switched off and the bath water has been drained from the whirlpool tub.
  • the nozzle body according to the invention also has an air inlet opening which opens into the nozzle channel adjacent to the water inlet. This inevitably forms a venturi nozzle effect, which ensures entrainment of the desired amount of air with the pressurized water entering the nozzle body.
  • the air inlet opening should, preferably vertically, open into the nozzle body from above, so that no residual water can remain in this area and in particular also in the air connection piece adjoining the air inlet opening, whereby of course the air supply line, at least in the area of the water jet nozzle, above the housing the same goes.
  • the venturi principle mentioned can be implemented in the invention in that the air enters the nozzle duct at an angle of preferably between 80 ° and 110 ° to the outlet axis of the nozzle duct.
  • the air supply line opens into the air inlet opening either directly or via a circumferential channel. If air can be supplied to the water jet in any rotational position of the nozzle body in the first case, the air inlet opening would have to take up a corresponding peripheral area, while in the second alternative the air inlet opening could be a circular cylindrical bore or recess in the nozzle body, while the peripheral channel takes up the desired peripheral area.
  • the assembly and maintenance of the whirlpool tub according to the invention can be ensured in a simple manner in the case of new installation, wear or defect of the nozzle body in that it is held interchangeably in the housing or the guide sleeve by means of an end cap which can be fixed directly or indirectly.
  • the nozzle body is not only guided radially in the housing or the guide sleeve but also axially reliably, the nozzle body is preferably axially received between the stop shoulders of the housing or the guide sleeve on the one hand and the end cap on the other.
  • the nozzle body preferably has an actuating section on the inside of the tub.
  • the housing 10 is part of a pipeline system and is connected at the end face to a pressurized water line 15 via a water connection stub 13 and in its upper jacket region via an air connection stub 14 to an air supply line 16.
  • the fastening sleeve 11 lies with an enlarged flange 8 on the inside of the tub on the surface 33 of the wall section 7.
  • the housing 10 projects into the fastening sleeve 11 only over part of the length thereof, namely up to a stop ring 12.
  • a guide sleeve 17 is arranged in the housing 10 in a rotationally fixed manner.
  • the guide sleeve 17 has in its bottom region a water passage opening 18 which is in flow connection via the water connection piece 13 with the pressurized water line 15, and in the upper region of its jacket an air passage opening 22 which is in flow connection with the air supply line 16 via the air connection piece 14.
  • a nozzle body 20 provided with cylindrical guide surfaces is rotatably mounted about a horizontal axis of rotation D.
  • the axial positioning of the nozzle body 20 in the guide sleeve 17 and the housing 10 takes place in that the nozzle body 20 with a the shoulder facing away from the tub interior 32 abuts on a tub-side stop shoulder 4 of the guide sleeve 17 and with its tub-inside end on a stop shoulder 5, which is formed on an end cap 28 which is screwed into the fastening sleeve 11 and the flange 8 of the fastening sleeve 11 with a cover flange 9 covered.
  • the threaded section 29 of the end cap 28 ends in front of the front end of the housing 10 facing the tub interior 32.
  • the tub-side section of the nozzle body 20 is against the housing 10 by means of a sealing ring 26, the casing of the housing 10 relative to the fastening sleeve 11 by means of a sealing ring 30 and the flange 8 of the fastening sleeve 11 is sealed off from the surface 33 of the wall section 7 facing the tub interior 32 by means of a sealing ring.
  • a nozzle channel 23 is formed with a straight exit axis K, which extends at an angle ⁇ with respect to the horizontal axis of rotation D.
  • a water supply channel 21 which is provided coaxially to the nozzle channel 23 in the end wall 2, opens and is in flow connection via a water inlet opening 25 with the water passage opening 18 in the bottom of the guide sleeve 17.
  • the nozzle channel 23 opens into the tub interior 32 via a jet outlet opening 24.
  • the jet outlet opening 24 lies deeper than the water inlet opening 25 of the nozzle channel 23 and the latter higher than the pressurized water line 15 Outflow rotational position, the residual water flows out of both the nozzle channel 23 and the water supply channel 21 when the whirlpool device is switched off and the bath water is drained from the tub interior 32.
  • the jet outlet direction can be changed by the rotatable mounting of the nozzle body 20 and the inclined inclination of the outlet axis K of the nozzle channel 23 with respect to the axis of rotation D.
  • the nozzle body 20 In its jacket area, the nozzle body 20 also has an air inlet opening 19 which, in the outflow rotational position of the nozzle body 20 shown, coincides with the air passage opening 22 of the guide sleeve 17. In this rotational position, the residual water can also flow completely out of this area and the adjoining air connection piece 14. In other rotational positions, the air passage opening 22 of the guide sleeve 17 can be in flow connection with the air inlet opening 19 of the nozzle body 20 via a circulation channel 3, so that air can be supplied to the nozzle channel 23 in any rotational position of the nozzle body 20.
  • pressurized water can be supplied to the nozzle channel 23 in any rotational position of the nozzle body 20 because the water passage opening 18 in the bottom region of the guide sleeve 17 is designed and dimensioned so large that the water inlet opening 25 of the nozzle body 20 is in flow connection with the latter in every rotational position.
  • the air inlet opening 19 opens directly in the vicinity of the water supply channel 21 into the nozzle channel 23, at an angle ⁇ to the outlet axis K, so that a venturi effect arises and the pressurized water entering the nozzle channel 23 via the water supply channel 21 entrains air from the air supply line 16 .
  • An actuating section 27 is formed on the nozzle body 20 on the inside of the tub, which facilitates the rotation of the nozzle body 20 by hand.
  • a guide sleeve 17 is dispensable since the nozzle body 20 is rotatably mounted directly in the housing 10 with a rear sleeve-shaped section.
  • the supply of pressurized water and air is designed somewhat differently than in the embodiment according to FIG. 1, but the mode of operation, in particular also with regard to the formation of a venturi effect, is the same.
  • the nozzle body 20 is in its drain rotation position. From this it can be seen that the jet outlet opening 24 is also lower than the water inlet opening 25 and the latter higher than the pressurized water line 15, so that no residual water remains in the nozzle outlet area when the whirlpool device is put out of operation.
