Definitions

  • the invention relates to an outlet nozzle for the outlet valve of a whirlpool tub with a water supply channel and an air supply channel, in which the water flow is mixed with the air flow due to the action of an injector.
  • a nozzle combination with an axially movable jet deflection plate which can achieve sealing on its circumferential line with respect to a nozzle housing.
  • a water supply line opens into the nozzle housing below the jet deflection plate, while air can be supplied to the lower opening of the nozzle housing.
  • the beam deflection plate has a cylindrical approach, in which irradiation openings are kept clear. When the water supply line or the opening is pressurized, the jet deflecting plate can lift axially upwards from its lower sealing position up to a stop, as a result of which water and air can escape together from the jet openings into the tub interior.
  • the disadvantage here is that the position of the jet deflector can be influenced from the outside, in particular the jet deflector is pressed into the closed position under the body weight of the tub user, which due to the geometric conditions the injector effect is only relatively small and that the jet deflector is only returned to its sealing position due to its own weight reached.
  • a nozzle for an air bubbler of a water basin is proposed, which is supplied through a channel with water.
  • a check valve is provided at the nozzle outlet, which is opened by pump pressure and closes automatically, preferably by spring force or moved by the bath water flowing back in, as soon as the pump pressure is switched off.
  • the flow rate can also be regulated by means of the check valve by opening more or less cross-section.
  • the check valve acts as a baffle plate and widens the escaping water jet, which improves the mixing of air and water and reduces the size of the air bubbles.
  • DE-U-8 606 463 (FIG. 10) also proposes a nozzle combination in which the extension of an air supply nozzle projects into the air-guiding channel. Coaxial to the air supply nozzle, a support flange is inserted into the basin wall, which carries an axially adjustable ring with a conical inner bore, which together with the air supply nozzle forms an annular channel, the free cross section of which can be changed by adjusting the ring. Dirty bath water can penetrate into the nozzle combination and deposit there.
  • DE-U-8 606 463 (FIG.
  • nozzle combination in which a water-air mixture is fed via a check valve to an axially fixed baffle plate through which the water-air mixture passes axially and under which the water-air mixture can exit into the interior of the pool through an outlet opening parallel to the pool floor.
  • dirty bath water can accumulate inside the nozzle housing.
  • a device must be connected upstream, with which the water-air mixture is first produced.
  • a nozzle combination for the supply of compressed air is also proposed, in which in a carrier flange which in the The basin wall or the pelvic floor is clamped, a cover valve is seated, which in the idle state runs almost at the same level as the installation level, is lifted out of its seat when pressure is present and releases the outlet path for the compressed air. When the air pressure drops, the cover valve is returned to its valve seat. This can be done by the water column in the inner pool or by its own weight or by spring force.
  • a check valve can be provided in the supply line.
  • the compressed air can exit axially or essentially radially into the inner basin. Through the axial outlet opening, contaminated bath water can penetrate into the nozzle housing and settle there even when the nozzle combination is closed. An injector effect is not intended, a special device would be required for this. Another disadvantage is that the opening position can be affected by the pool user.
  • a nozzle combination is known from EP-A-0 209 646 (FIG. 10), which belongs to the state of the art only according to ⁇ 54 (3) EPC, but which essentially corresponds to the nozzle combination of FIG. 10 of DE-U-8 606 463 additionally has an independent check valve in the outlet channel of a steering jet nozzle.
  • the check valve is already loaded with a water-air mixture so that there is no longer any injector effect.
  • the air supply nozzle is also provided with an outer ring-shaped stop, which means that if a ring is adjusted, the volume can be regulated until the air supply is completely shut off.
  • the ring used to adjust the volume can also be equipped as an independent check valve or the restoring force of the returning bath water can be used. This creates a relatively complex construction and the additional disadvantage that on the one hand on the check valve formed by the adjustable ring the compressed air and on the other hand the water pressure acts, which creates undefined conditions.
  • the object of the invention is to design an outlet nozzle of the type mentioned at the outset such that a high hydro-pneumatic massage effect can be achieved if the outlet nozzle is prevented from being contaminated by impurities present in the water of the whirlpool.
  • an outlet nozzle for the outlet valve of a whirlpool tub with a water supply channel and an air supply channel in which the water flow is mixed with the air flow due to the action of an injector, in that the water supply channel merges into a radially outwardly leading annular outlet channel , which is formed in a plate-shaped distribution body and the valve body of the outlet valve, that the preferably annular air supply duct opens into an annular space between the plate-shaped distribution body and the valve body or the valve housing or the tub wall which adjoins the outlet duct radially outwards, and that with the inner surface of the distribution body, the outlet channel and / or the surfaces forming the intermediate space of at least one concentrically surrounding the water supply channel Precise piston movable relative to the valve body are formed, which in its closed position closes the outlet channel and / or the space adjoining the outlet channel in a liquid and / or gas-tight manner.
  • the contaminants in the water of the whirlpool such as hair, dirt particles or the like, cannot settle in the outlet nozzle and thus lead to a functional impairment or even blockage of the outlet nozzle.
  • the piston While in the open position of the piston or pistons Piston surfaces with the inner surface of the distribution body form the outlet channel and the space adjoining it radially outwards, the piston moves or the pistons move with their surfaces essentially axially toward the inner surface of the distribution body when the outlet nozzle is switched off, so that at least one opposite Areas of these surfaces ensure a liquid-tight seal of the water supply duct and / or the air supply duct.
  • the at least one piston is expediently guided in the valve body or on the valve housing or on the tub wall for the axial stroke movement.
  • the air supply duct has individual air supply ducts which are in flow connection with bores which extend axially in the piston.
  • the bores of the air supply duct can merge into an annular duct opening into the intermediate space.
  • the bores arranged in the piston or the annular duct of the air supply duct open or open into the intermediate space immediately behind an outlet slot formed in the edge region of the outlet duct.
  • the surfaces of the distribution body and the piston that come into contact with one another in the closed position of the piston but at least the areas of the surfaces of the piston that come into contact with the inner surface of the distribution body as sealing surfaces, optionally with a flexible surface Coating or a pad or insert made of rubber or the like.
  • the surfaces of the piston which extend to the bores or the annular channel of the air supply channel or which extend on both sides of the outlet slot of the outlet channel are arranged such that they are offset with respect to one another in such a way that they correspond to the inner surface of the distribution body Surface delimiting the space jumps back relative to the surface delimiting the outlet channel, and that the piston wall adjoining the surface delimiting the outlet channel has a recess in the region of the outlet slot or the air supply channel, via which a sealing strip of flexible material connected to the piston surface is flexible in the open position of the piston Material, possibly with the formation of the outlet slot, extends in a substantially tangential direction to the piston surface, which is pressed into the recess in the closed position of the piston.
  • This advantageous embodiment according to the invention makes it possible to provide only a reciprocating piston with bores for the air supply and at the same time to keep the height of the intermediate space larger than the width of the outlet slot for a uniform flow of the water-air mixture and low noise.
  • the recess in the piston wall is provided with an axial depth which is approximately the result of the piston surface assigned to the intermediate space and over itself Air supply channel or the bores in the piston tangential inwardly extending line is specified.
  • the front section of the sealing strip which projects beyond the expansion and in the open position of the piston with the inner surface of the distribution body forms the outlet slot, is pressed into the recess in the closed position, the resulting bead of the flexible sealing strip being pressed against the inner surface of the distribution body.
  • the piston can be moved from the closed position into the open position against the force of a spring energy store by the force or pressure of the water flowing out of the water supply channel.
  • the spring force accumulator is advantageously formed by springs, rubber buffers or the like, which are arranged in an annular space that essentially concentrically surrounds the water supply channel between the piston and a bearing surface of the valve body.
  • the annular space provided in the valve body has a wall area extending axially upward from the support surface for receiving the piston mounted on the spring force accumulator, that an inner wall area arranged concentrically to the water supply channel of the piston forms an annular gap with the wall region of the valve body facing it, and that the annular space opens into a return channel which extends axially downward in the valve body and which is possibly connected to the outflow of the whirlpool tub via a shut-off device.
  • cleaning of the outlet nozzle according to the invention is advantageously achieved by injecting a cleaning liquid through the water supply channel into the outlet nozzle, and thus an outlet channel which is sealed against the ingress of water and possibly against a supplied air, and which is injected via the water supply channel into the Valve body provided annular space flows and from there through a return channel into the drain of the jacuzzi.
  • the pressure of the cleaning liquid emerging from the outlet openings of the water supply channel is to be determined such that the piston or pistons remain or remain in their closed position. This achieves an effective backwashing or cleaning of the outlet nozzle according to the invention.
  • ring-shaped rubber buffers concentrically surrounding the water supply channel are provided on both sides of the air supply channel, which at least in the closed position of the piston keep an area of the annular space free and thereby separate them from one another in two liquid and / or gas-tight manner Divide sections with the radially outer section communicating with the air supply duct.
  • the annular gap expediently has approximately half of the Width of the outlet slot corresponding width of 0.1 to 1 mm, preferably 0.6 mm, so that in the open position of the piston even in the absence of a shut-off element between the return channel and the outflow of the whirlpool, only a small amount of the water introduced into the water supply channel during operation the outlet nozzle is lost.
  • the distribution body can be held, for example, by a bayonet, screw, suction, plug-in or magnetic connection on the valve body, which may have an axial extension, or be formed integrally therewith. Further advantageous features of the outlet nozzle according to the invention emerge from claims 14 to 20. These serve essentially a simple construction with high effectiveness of the emerging massage jet.
  • the outlet nozzle according to the invention can in particular also be operated with a pulsating water supply and / or air supply.
  • the single figure schematically illustrates in section an embodiment of an outlet nozzle according to the invention with a closing mechanism and a backwash system.
  • the outlet nozzle shown in the drawing for the outlet valve 34 of a whirlpool has a valve body 39 with a centrally arranged water supply channel 35, which is provided with outlet openings 56 opening radially into an outlet channel 36.

  • the height of the outlet channel 36 is reduced from the radially inside to the radially outside by the surface 44 of the piston 49 tapering obliquely towards the tub wall 42 from the radially inside to the radially outside and the inner surface 41 of the distribution body 37 from a radially inner one, approximately parallel to the tub wall 42 extending section merges into an obliquely inclined area, whereby an outlet slot 45 is formed on the radially outer circumference of the outlet channel 36.
  • This outlet channel 36 which tapers radially from the inside to the outside, gives the water emerging from the outlet openings 56 the speed required to exert a suction effect on the outlet behind the outlet slot 45 directly behind the outlet slot 45 via an axially extending upward in the valve body 39 if necessary, exercise air introduced into the air supply duct 38, which has individual air supply ducts 53.
  • the mixing of the water with the sucked-in air takes place in a space 46 adjoining the outlet channel 36 radially outwards.
  • This space 46 is formed by the outer edge region of the inner surface 41 of the distribution body 37 and the surface 48 of the piston 49.
  • the intermediate space 46 which is designed as an annular channel, extends away from the tub wall 42 at a slight angle.

If, on the other hand, the outlet valve 34 is slatted off, the restoring force of the spring-core accumulator 60 brings about an axial stroke of the piston 49, the end region of its surface 44 and its surface 48 being pressed against the inner surface 41 of the distribution body 37 and thus the outlet valve 34 against inflow of bathing water seal from the whirlpool tub.
  • the sections of the surfaces 44 and 48 that come into contact with the inner surface 41 of the distribution body 37 in the closed position of the piston 49 are provided with a sealing strip 59.
