Abstract

A sanitary outlet unit (1) is provided, including an outlet armature (2), with a flow regulator (4) in a region of the water outlet (3) thereof, wherein an aeration device is provided for aeration of the water flow. The outlet unit (1) provides that the aeration unit (5) is located in the outlet armature (2) and/or in at least one water line leading to the outlet armature (2) separately from the flow regulator (4). Through the spatial separation of the functions of flow shaping or water discharge and the aeration of the water flow, there are many possible embodiments for optionally providing the water outlet (3) of the sanitary outlet unit (1) with an extremely thin design.

Description

The invention relates to a sanitary outlet unit with an outlet fitting, which has a water outlet, wherein for ventilating the water flow, a ventilation device is provided, which is provided in the flow direction at a distance from the water outlet in the outlet fitting and / or in at least one of the water supply lines leading to the outlet fitting.

Various jet regulators are already known, which ventilate the water jet emerging from a sanitary outlet fitting and form it into a homogeneous, pearly-soft water jet. The previously known jet regulators have in their jet regulator housing to a, usually designed as a perforated plate jet disintegrator, which is followed by a homogenizer and optionally a flow rectifier. In the region of the homogenizing device, the jet regulator housing of the previously known jet regulators has ventilation openings which serve as ventilating means for aerating the water jet temporarily divided into individual jets by means of the jet separator (cf. DE-A-30 00 799 ). The previously known jet regulators are used with their jet regulator housing in an outlet mouthpiece that can be releasably secured to the fitting outlet by means of a screw connection.

The outlet nozzle required for mounting the previously known jet regulators determines the shape of sanitary outlet fittings in the area of the valve outlet. However, there is an increasing desire to design unconventional and aesthetically sophisticated outlet fittings.

From the DE 1 209 515 A already a sanitary outlet unit with an outlet fitting is known, which has a water outlet and a ventilation device for aerating a pressurized water jet flowing, wherein the ventilation device is provided in the flow direction at a distance in front of the water outlet in the outlet fitting. To the aeration device not in one on the free. In order to provide a ventilation device that allows any form of water outlet to a sanitary outlet fitting, a horizontal inlet pipe of the known outlet unit has a transversely passing through the inlet pipe and pierced transversely for the passage of water through the end of the outlet nozzle screwed mouthpiece with compulsory cylindrical cross-section Pipe sleeve, which protrudes at its one end face from the wall of the inlet pipe, preferably downwards, and there is open to receive a sealing in the pipe sleeve sealing plug with an opening into an axial air intake cavity and a mixing and dividing having insert. From DE 1 209 515 A However, previously known ventilation device is only used in such fitting designs in which the horizontal inlet pipe above the washbasin comes out of the wall and the water outlet is thus arranged lower than the ventilation device. The previously known discharge unit is thus limited to a specific, narrowly defined area of use.

From the DE 1 220 345 A is known a pull-out arm. Such Ausziehschwenkarme usually have an air admixing device. In these extendable swing arms no conventional jet regulator can be screwed at the outlet end, as it is due to the backflow to automatic extraction of the extendable swing arm and leaks could lead. The jet regulator is therefore attached to such telescopic pivot arms on the mounting side arm portion, the required air intake then takes place there. However, such extendable swivel arms are often mounted so that the swivel tube is above the faucet to compensate for a low altitude of the tap above the outlet basin. Since with only a small turn of the tap, the water on the outside of the nozzle can flow downwards and drip through the air inlet openings, the air admixing is in the off DE 1 220 345 A previously known Ausziehschwenkarm arranged at the outlet end or near the outlet end of the adjoining the Wasserzapfstelle pivot tube. At the DE 1 220 345 A Previously known Ausziehschwenkarm so a leak is counteracted by the special arrangement of the air inlet openings at the outlet end or close to the outlet end, this from DE 1 220 345 A previously known swivel arm always requires the arrangement of the water outlet below the air inlet opening to prevent leakage of the remaining water in the water outlet through the air inlet openings when closing the faucet.

From the DE 199 01 704 A1 One already knows a hand shower, which has a switching device for influencing the exiting water jet. By actuating the switching device, an air suction device in the manner of a water jet pump is switched on or off. The switching device of the prior art hand shower is designed such that its passage cross-section is expandable when switching off the air intake, so that in this unthrottled position a comparatively strong, air-free and usable for massage purposes, for example, water flow can be delivered, while in the throttle position on the other hand soft, strongly enriched with air and mixed water jet can be discharged. In the ventilation device of the prior art hand shower a preferably rubber-elastic valve body is used, which forms a seated in the intake port valve in the open position. This can preferably open automatically in the intake direction, however, in the opposite direction, on the other hand, close automatically to reliably prevent unwanted water leakage.

It is now the task of creating a sanitary outlet unit of the type mentioned above, which offers the greatest possible freedom of design with at least the same functionality in the design of their outlet fitting

The inventive solution to this problem is in the sanitary outlet unit of the type mentioned in particular that the ventilation device is located lower than the water outlet of the outlet fitting in at least one use position and that the ventilation device has at least one one-way vent valve.

Since in the outlet unit according to the invention, the ventilation device is arranged in the flow direction with distance in front of the water outlet and thus since a spatial separation between the water outlet of the outlet fitting on the one hand and the ventilation device can be achieved on the other hand, the ventilation device of the outlet unit according to the invention can also be arranged deeper than the water outlet. Since the ventilation device of the outlet unit according to the invention has at least one one-way vent valve, a 'flowing out of the water at the outlet fitting still in the outlet fitting water is avoided by the ventilation device even if this ventilation device deeper than the water outlet is arranged in the water outlet of the outlet fitting according to the invention, for example, a beam shaping, while on the other hand, the air intake is optionally also the determination of the flow rate is moved to a further upstream point. This spatial separation of the water outlet can be issued even extremely slim, so that without sacrificing functionality in a maximum design freedom in the design of such outlet units is achieved.

A particularly advantageous embodiment according to the invention provides that the outlet fitting has a jet regulator in the region of its water outlet, and that the ventilation device is provided separately from the jet regulator in the outlet fitting and / or in at least one of the water pipes leading to the outlet fitting. In this preferred. Embodiment takes place a spatial separation between the ventilation of the water jet on the one hand and the beam shaping provided in the beam shaping on the other. The beam forming takes place at the water outlet of the Auslaufarmaitur, while the air intake is provided in the flow direction at a distance in front of the water outlet.

In this case, a preferred embodiment according to the invention provides that the ventilation device has at least one duck bill or diaphragm valve and / or at least one umbrella or umbrella valve.

In order to optionally obtain a ventilated or non-aerated water jet from the outlet unit according to the invention, it is expedient if the ventilation device can be opened and closed.

In this case, a particularly simple and connected with only little manufacturing effort embodiment according to the invention provides that the ventilation opening of the ventilation device is preceded by a closure lid, which releases the ventilation opening in an open position and sealingly closes the ventilation opening in a closed position.

So that the water jet flowing through the aeration device can suck in the air and entrain it with thorough mixing, it is advantageous if immediately before a mixing zone forming mouth of the air and water supply an acceleration section is interposed in the water supply to accelerate the air to be mixed with the water flow.

In this case, a preferred embodiment according to the invention provides that the acceleration section is formed as a cross-sectional constriction of the inflow-side water line to the aeration device.

A better air mixing of the water jet is achieved when the ventilation device is connected downstream, leading the aerated water flow to the inner circumference of the water pipe or the outlet fitting water. In this particularly advantageous embodiment, the water jet emerging from the ventilation device is deliberately directed to the walls of the fitting housing in order to be reflected there and thus to be better swirled.

In this case, a particularly simple and associated with low production cost embodiment according to the invention, that the water supply is designed as a flow direction V-shaped or funnel-shaped leading grid, the grid openings defining guide walls are designed as water guide walls.

The grid openings of the guide grid have a large flow cross-section and are nevertheless able to guide the water jet well with the guide walls delimiting the grid opening, if the grid openings of the guide grid are configured substantially honeycomb-shaped.

It is expedient if the ventilation device as Einsetzpatrone or cartridge is designed, which is inserted into the leading to the water outlet pipe or fitting section.

A preferred embodiment according to the invention provides that the cartridge housing of the ventilation device on the inflow side has at least one passage opening, and that the at least one passage opening is designed as an acceleration section.

It is advantageous if the water supply is provided in the region of the housing outlet of the cartridge housing.

The ventilation device can be used particularly well in the fitting housing when the valve outlet of the at least one ventilation valve is arranged in the region between the acceleration section and the housing outlet of the cartridge housing.

In this case, a preferred embodiment according to the invention provides that in the fitting housing at a distance from the water outlet to the light fitting cross-section leading insertion opening is provided, in which the ventilation device is preferably releasably insertable.

An aerating device designed as an insert cartridge or cartridge can be used directly in a cast housing designed in particular as a cast body, if the receptacle for this insert cartridge or cartridge is machined accordingly in the valve body. An advantageous embodiment according to the invention, in contrast, provides that the insertion opening opens into a preferably sleeve-shaped cartridge or cartridge receptacle, the intended for receiving the ventilation device designed as an insert cartridge or cartridge. This sleeve-shaped cartridge or cartridge receptacle can be made for example of a thin-walled sheet metal construction, which is mounted in the valve body of the outlet fitting.

It is possible to provide the ventilation device directly in the fitting housing of the outlet fitting. In addition or instead, the ventilation device can also be arranged in a line adapter which can be interposed in at least one of the water lines leading to an outlet fitting.

The ventilation device can, barely visible, also mount below a washbasin when the ventilation device is arranged in a line adapter, which is interposed in at least one leading to an outlet fitting water pipes.

It is a particular advantage of a arranged in a line adapter ventilation device that the ventilation device can be interposed in the hot water or cold water pipe. If the ventilation device is interposed in the hot water or the cold water line, can be easily seen from the jet pattern, whether it is the water jet flowing out of the outlet fitting to hot or cold water. For example, if an air addition is provided in the hot water line, while the cold water supply is not assigned to a ventilation device, means a crystal clear stream of water that it is cold water, while a highly aerated water jet hot water and a little aerated water jet indicates mixed water. The user can thus detect the approximate temperature state of the effluent from the outlet fitting, water on the basis of the degree of air mixing, for example, based on the turbidity and whitening by the water bubbles.

It may be advantageous if the outlet fitting shower head is formed. Preferred application examples provide that the outlet fitting is designed as a hand and / or kitchen shower.

Normally, such kitchen showers have the option to change the water jet from spray jet to normal jet. By integrating a possibly also closable ventilation device, for example in the shower handle of such a hand or kitchen shower, it is also possible for the user to make the spray jet or the normal beam either with air mixing or without air mixing, so that the possibilities of beam variations doubled by such a ventilation device which adds value to the user.

In the FIGS. 1 to 7 a sanitary outlet unit 1 is shown in different views. The outlet unit 1 has an outlet fitting 2, which in the region of its water outlet 3 a in FIG. 2 has illustrated jet regulator 4, which is to form the emerging water jet homogeneous. In order to aerate the water jet and to produce a sparkling-soft water jet, a ventilation device 5 is provided.

From a comparison of FIGS. 1 to 3 It is clear that the ventilation device 5 is provided separately from the jet regulator 4 in the outlet fitting 2. In the fitting housing the outlet fitting 2 is to the upstream with distance from the water outlet 3 and the beam there 4 located on the side of the valve body to a clear fitting cross-section leading insertion opening 6 is provided. This insertion opening 6 leads to a arranged in the valve body sleeve-shaped cartridge or cartridge receptacle 7, which is manufactured as a thin-walled sheet metal construction and is designed to open and downstream open.

The ventilation device 5 designed as an insert cartridge or cartridge is detachably insertable via the insertion opening 6 into the sleeve-shaped cartridge or cartridge receptacle 7 and is held therein by means of a snap ring 8 which can be inserted into an opening-side groove 9 in the cartridge receptacle 7.

In the case of the outlet unit 1 shown here, the jet shaping effected by the jet regulator 4 remains at the water outlet 3 of the sanitary fitting 2, while the air intake and the determination of the flow rate is moved to a point located further upstream. Since the water outlet 3 is at the highest point of the outlet fitting 2, the ventilation device 5, a one-way vent valve 10, which is designed here as duck-bill or diaphragm valve and leakage of the closing of the outlet fitting 2 therein still water through a below intended to prevent the water outlet 3 arranged ventilation opening. The one-way vent valve 10 is visually covered by a header grid 40, which also serves as a screen.

In the FIGS. 3 and 6 It can be seen that the cartridge housing of the ventilation device 5 on the inflow side has a plurality of passage openings 11 designed as cross-sectional constrictions, which form an acceleration section 12 for accelerating the water flow to be mixed with the air. The ventilation device 5 is a, the ventilated water flow the inner circumference of the water pipe and especially the outlet fitting 2 leading water supply 13 downstream, which is designed as a flow direction V- or funnel-shaped tapered guide grille 14, the grid openings defining guide walls are designed as water guide walls. In order to keep a maximum flow cross-section and at the same time be able to continue the water flow as best as possible to the guide walls defining the grid openings, the grid openings of the guide grid 14 are configured substantially honeycomb-shaped. The serving as a water guide rail 14 is provided in the region of the housing outlet of the cartridge housing and held downstream of the cartridge receptacle 7.

In the area between the acceleration section 12 and the housing outlet of the cartridge housing, the valve outlet of the ventilation valve 10 is arranged. The valve outlet of the vent valve 10 opens into a mixing zone, which is arranged in the mouth of air and water supply. The accelerated in the acceleration section 12 water flow is good to suck the air coming from the vent valve 10 into the mixing zone, mix and entrain.

The spatial separation of the function water outlet and water forming on the one hand and the air intake in the ventilation device 5 on the other hand makes it possible to make the water outlet 3 of the outlet fitting 2 extremely slim.

In the FIGS. 8 and 9 a ventilation device 5 is shown, which for a, with Figure 1 to 7 comparable outlet unit is determined. For ease of illustration, the V-shaped guide grid 14, which is to serve for better turbulence, not included. The in the FIGS. 8 and 9 Ventilation device 5 shown has a protective cage or jacket 15 which is open on the downstream side and surrounds the ventilation valve 10 in its partial region projecting into the mixing zone. The protective cage 15 is intended to prevent the occurring in the acceleration section 12 at high speed, sharply focused water jets impinge directly on the vent valve 10 and lead to malfunction.

In the FIGS. 10 to 12 is one with FIGS. 8 and 9 comparable ventilation device 5 shown, the vent valve 10 is configured here as Umbrella or umbrella valve. Compared to that in the FIGS. 1 to 9 shown diaphragm valve is the umbrella valve 10 in FIGS. 8 and 9 comparatively flat and has a much lower height.

In the FIGS. 13 to 17 a sanitary outlet unit 1 is shown with a ventilation device 5, which is openable and closable. The ventilation opening of this ventilation device 5 is preceded by a closure lid 16 which releases the ventilation opening in an open position and sealingly closes the ventilation opening in a closed position.

By turning the closure lid 16, the air supply is closed, so that the user can choose freely whether he wants a water outlet in ventilated form or in non-ventilated form. By turning the closure cap 16, the O-ring 17 located in the closure cap 16 releases from its seat, so that an air intake through the ventilation valve 10 into the water flow is possible. Turning the closure lid 16, which is for example via a thread with the cartridge or cartridge housing of the ventilation device 5 in conjunction, until the O-ring 17 of the closure lid 16 frontally rests on the vent valve 10 or the ventilation device 5, so that the air supply is prevented via the vent valve 10, so that the water flowing through the sanitary outlet unit 1 water is no longer ventilated.

In the FIGS. 18 and 19 a ventilation device 5 is shown, which can be inserted through the insertion opening 6 directly into the cast body of the outlet fitting. Unlike in the FIGS. 1 to 17 shown ventilation devices 5 comes the ventilation device according to the FIGS. 18 and 19 without a sleeve-shaped cartridge or cartridge holder, because the for the ventilation device 5 according to the FIGS. 18 and 19 certain recording is incorporated directly in the casting from the outlet fitting 2 machined.

In the FIGS. 20 to 22 is a sanitary outlet unit 1 shown, which is designed as a shower head. In the leading to the shower head 30 hose 18 a ventilation device 5 is interposed, which is arranged in a line adapter 19. As if from a comparison of FIGS. 20 and 21 becomes clear, the sleeve or pipe section-shaped line adapter 19 has at its one end an internal thread, which can be screwed onto a provided on the fitting outlet 20 of the outlet unit 1 threaded connector. At the opposite end region of the line adapter 19, an external thread is provided, onto which the hose line 18 leading to the shower head 30 can be screwed. The ventilation device 5, which can be inserted into the line adapter 19 through a lateral insertion opening 6 and is likewise secured there by means of a snap ring 8, can be opened and closed via the closure cover 16. The line adapter 19 can also be retrofitted to any commercial Hose line 18 are connected. The line adapter 19 with the ventilation device 5 located therein allows the user to produce a ventilated or even an unventilated spray jet. The ventilation will be similar as in the FIGS. 13 to 17 - By obstructing the air supply by rotating the sealing cap 16 - causes.

In the FIGS. 23 to 25 is a connection unit 1 shown with an outlet fitting 2, in whose hot water and their cold water inlet in each case one, located in a line adapter 19 ventilation device 5 is interposed. With the retrofittable line adapter 19 and the ventilation devices 5 located therein, it is possible to selectively release a ventilated or an unventilated water jet at the outlet fitting. It is a special advantage in the FIGS. 23 to 25 illustrated outlet unit 1, that optionally only one of the two supply lines can be provided with air. By provided on the aeration devices 5 cap 16 can be mixed with air only optionally the hot water or cold water inlet. This makes it possible to detect from the spray pattern, whether it is hot or cold water; is the cap 16 of the interposed into the hot water supply ventilation device 5 and closed the closure lid 16 of the cold water inlet associated ventilation device 5 means an unperforated and correspondingly crystal clear water jet that cold water leaking, while a highly aerated water jet to hot water and a little ventilated drain water indicates mixed water. The user can thus see the approximate temperature state of the water jet on the basis of the degree of air mixing, namely on the basis of the turbidity and whitening by the water bubbles visible in the outflowing water.

In the FIGS. 26 to 29 an outlet unit 1 is shown, which is designed here as a hand or kitchen shower. In the configured as a hand or kitchen shower outlet unit 1 according to the FIGS. 26 to 29 the ventilation device 5 is integrated directly into the shower handle. The shower handle of the hand or kitchen shower has for this purpose in the hollow and designed as a water pipe handle interior of the shower handle leading insertion opening 6, in which the ventilation device 5 can be used from the outside. Normally, such hand or Küchenbrausen have the ability to switch from spray jet to normal jet and vice versa. By integrating a ventilation device shown here, which in turn can be opened and closed, for example by means of a closure lid 16, it is also possible for the user to make the spray or the normal jet either with or without admixing with air, so that the possibilities of beam variations by the here provided aeration device 5 are doubled, which brings the user an additional benefit.

In the FIGS. 30 to 34 a further embodiment of a ventilation device 5 is shown, which differs from the example in the Figures 3 and 8th shown differs among other things by a configured as Umbrella or umbrella valve 10 ventilation valve. The ventilation device 5 according to the FIGS. 30 to 34 is designed as Einsetzpatrone or cartridge, soft - similar to the ventilation devices shown in the previous figures - in a upstream with distance from the water outlet arranged sleeve-shaped cartridge or cartridge receptacle is used.

Also the cartridge case in the FIGS. 30 to 34 shown aeration device 5 has on the inflow side a plurality of cross-sectional constrictions formed through openings 11 which form an acceleration section 12 for accelerating the mixed with the air flow of water. In this case, the ventilating device 5 also here one, the aerated water flow to the inner circumference of the water pipe and especially the outlet fitting leading water supply 13 downstream, which is formed as a flow direction V- or funnel-shaped tapered guide grille 14, which configures the grid openings defining guide walls as water guide walls are. The lattice openings of this guide lattice 14 are also substantially honeycomb-shaped, in order to keep the largest possible flow cross-section and at the same time to be able to continue the water flow as best as possible at the guide walls delimiting the lattice openings. The serving as a water guide rail 14 is provided in the region of the housing outlet of the cartridge housing and held downstream of the cartridge receptacle.

In the area between the acceleration section 12 and the housing outlet of the cartridge housing, the valve outlet of the ventilation valve 10 is arranged. The valve outlet of the ventilation valve opens into a mixing zone, which is arranged in the mouth of air and water supply. The accelerated in the acceleration section 12 water flow is good to suck the air coming from the vent valve 10 into the mixing zone, mix and entrain.

The vent valve 10 in the FIGS. 30 to 34 shown ventilation device 5 is in the FIGS. 35 to 43 shown in more detail. How out FIG. 36 becomes clear, acts on the valve screen 50 of the umbrella valve designed as a vent valve 10 the valve seat 51 with an obtuse-angled corner region 52 of its Schirmumfangsrandes circumferentially linear and with a graded over the Schirmumfang.abgestuften bias. This, the valve seat 51 acted upon stepped bias of the valve shield 50 is achieved in that the valve seat forming the support surface has different heights and that the valve seat 51 is disposed in a plane which is arranged at an angle to the plane defined by the Schirmumfangsrandbereich the unloaded valve shield 50 level is. By this linear admission of the valve seat 51 on the one hand or the stepped bias of the valve seat 51 bearing on the valve shield 50 on the other hand, air can be sucked through the vent valve 10 without the valve screen 50 comes into vibration and produces unwanted trumpet-like noise.

The water flow leading portion 57 of the ventilation device 5 is separated from the one-way vent valve 10 by a labyrinth 53, which is formed by a plurality of, here three, staggered and spaced apart labyrinth walls 54, 55, 56 each having a portion of the cover between the vent valve 10 and section 57 arranged passage cross-section. In addition, the labyrinth 53 is provided in a cylindrical sleeve 58, which protrudes with its open and the venting valve 10 facing away from the sleeve end in the section 57. With the help of the labyrinth 53 and / or the cylindrical sleeve 58, a back splash of water during the air intake phase is prevented, which could otherwise lead to calcification on the valve screen 50 and disturbing water residues on the outer surface of the sanitary outlet fitting.
