DE10005660A1 - Bathtub outlet fitting has water outlet pipe via low-lying closure plug, suction connection that is in one piece with fitting instead of additional component - Google Patents

Abstract

The fitting has a housing, a vertically movable valve cone with a sealing ring and a suction connection that is in one piece with the fitting instead of an additional component as with a conventional fitting. Bathtub water can pass via a closure plug (18) as a connection for the whirlpool and also to an overflow pipe.

Description

The invention relates to a bathtub waste set in the one above, in the Line of symmetry of the bathtub drain hole Sealing plug, bath water on the one hand as an intake for whirlpool and on the other others can be derived into a tube communicating with the bathtub; this The set is also particularly suitable for mixed water supply in the area of the floor Trough, whereby the low-level bath inflow by means of a free flow path is secured against sucking back.

A drain over a lowered plug to a communicating Tube for pool overflow at the drain hole is known from patent DE 40 32 404 C2. The Drainage of bath water over one, not immediately under the drain hole arranged lowering plug for pumping a whirlpool is in patent DE 35 07 472 C2 proposed, in this embodiment by means of a spring which the Valve plug, or the plug is held under tension on the valve plug seat, is ensured that if in the clogged or covered floor outlet in the circulation pump leading connecting line negative pressure, this negative pressure does not arise to open the Sealing plug and thus lead to free access to the siphon. The Risk that the circulation pump could suck in dirty water or air from the siphon is therefore excluded. GM 298 23 01 includes a pull-out plug or Valve cone with an internal thread, secured against rotation Threaded sleeve is connected, in the thread of which a driving threaded spindle engages, suggested. Similar explanations can also be seen from 199 50 298.6, here in the vertical distance under the bathtub drain hole, in addition to the bathtub water Overflow pipe, with drain fitting screwed to the drain hole with the bathtub, for Maintenance accessible, the discharge of a drain pipe from the encapsulation space of the free Flow section for protection against back suction of the low-level mixed bath water Inflow is initiated. A drain head, at the overflow hole of the tub, with a free flow path, Low-level mixed water inflow and communicating tube for tub overflow on Drain hole can be seen in 199 58 312.9.  

Bathtub water drains under the drain hole of the tub to a whirlpool Intake manifolds are usually used as additional components on conventional drain sets put on, which then leads to a large height under the tub. In the course of the wish after low bathtub entry heights, this is uncomfortable. The intake manifold Execution in which the plug is held by a spring at its sealing seat is not integrated in a drain set under the drain hole. The Drain set in which the sealing plug is closed by means of a spindle drive without intake manifold.

The invention is based on the problem of a drain hole D2 = 52 or D2 = 90 usable z. B. horizontal heating mirror or ultrasonically welded drain fitting Housing, which preferably has a closing plug, the drainage option of bathtub water to integrate over this and not the possibility install, with fittings bolted to the tub, for maintenance, good accessibility to have an additional discharge of a further drain to a rum overflow pipe, whereby this derivation from the encapsulation space of the free flow section of the sublevel Mixed water inlet, from a drain funnel under a miniaturized hydraulic Three-chamber system separator for protection, also against back suction, the Disinfection of an air system whirlpool or from a mini slip shower Hose box can come under the top of a bathtub. Are preferred the discharge of the overflow and the discharge pipe, at least partially outside the Water trap. Theoretically, the overflow pipe and the overflow space in the Dry the drain head of the inlet and overflow set better to prevent the migration of To prevent bacteria and also then, when the plug is closed Air into the encapsulation chamber of the free flow path via the overflow and the discharge pipe be sucked. About the additional security slots in the encapsulation room that this connect with the space between the back of the bathtub and its tile covering, can also go there, if the tub is sealed completely theoretically, Get air.

This problem becomes clear with both drain sets for D2 = 52 and for D2 = 90, solved in that, when the set is attached to the tub, the plug with its Sealing seat is designed to be removable via the drain hole to the tub. In any case at  The extraction nozzle for the whirlpool is removed by pulling out the plug with its sealing seat also connected to the valve cone, for. B. with an internal thread provided, twist-proof threaded sleeve, in the thread of which the drivable Threaded spindle engages with removed. The upper part of the housing for D2 = 90 is with the upper housing part z. B. preferably one-piece bath water drainage shaft also, as with version D2 = 52 absolutely necessary two-part, d. H. by means of two in roughly rectangular, mutually parallel channels in the, above the lowered sealing plug or its sealing seat forming large cylindrical Space with an inside diameter of drain hole D2 = 90 minus twice the material thickness the edge with which the set is threaded into the drain hole for alignment, or diverted.

The three M5 fastening screws are, as can also be seen from FIGS . 1 and 5 of the above GM, freely running in the so-called large cylinder described above, or through the drainage space of the bath tub water, all around, in the upper part of the housing the removable sealing seat of the plug arranged, metal nut threaded parts. The plug-sealing seat is, as in vorst. GM described, removable, sealed snapped into the upper part of the housing. The bath water drainage space is sealed upwards, towards the bath tub, and outwards to the space between the back of the bath tub and its tile covering by the seal between the bottom of the drain hole and the upper collar on the housing. Despite the three M5 screws exposed within D2 = 90, after removal of the sealing plug with its sealing seat and spindle drive, there is good access to the so-called "visible" additional introduction and to the odor trap described in 199 50 298.6.

With the upper housing version for D2 = 52, good access is only structurally complex to achieve. Instead of the vorst. three M5 screws here is the one in the front. Note, there used as an individual part in FIG. 2c there, the so-called fastening pot with its two pull tabs with the dotted screw guides. Because of the accessibility, the diameter D ₂ = 52 +3 | -2 should only be reduced by twice the material thickness of the mounting pot, maximum 1.2 millimeters, i.e. to a minimum diameter of 47.6.

The so-called large cylindrical space described above is therefore in execution D2 = 52 through the, in the lower area slightly conical, in the upper cylindrical Part, di = 47.6, of the mounting pot can be removed by means of a radially sealing O-ring sealed cylinder, on the bottom of which the sealing seat for the plug is replaced. The double lateral discharge of the bath water from the front. slightly conical, cylindrical part takes place by means of two approximately rectangular windows, which on two opposite, horizontal bath water discharge channels I and II by means of two are also sealed in approximately rectangular flange O-ring seals. That for Removable bathtub, slightly conical at the bottom, cylindrical part, on the underside of which Sealing seat of the sealing plug and preferably, partially in one piece, its spindle drive, is the central tube of two concentric tubes according to the invention. The on both sides of the Outside diameter of the central tube, with their receptacles for the two above Window seals for bath tub drainage channels I and II are above the between the outer diameter of the central tube and the inner diameter of the outer tube, the upper part of the housing outer wall, forming an annular channel led away. Approximately at the same height with channels I and II are in the circular channel introduced the overflow pipe and the drain, from the encapsulation space of the free Flow section to secure the sublevel bath mixed water inflow. The two mounting straps, or pull tabs of the mounting pot, to the lower fastening screws, are in the circular channel, on the outside past the cylindrical, slightly conical part at the bottom with sealing plug and preferably spindle drive, led down, below the plug level. After removing this assembly is the so-called "visible" additional introduction, since it is directly under the tub drain hole lying, between the two flange O-ring seals of channels I and II, in Circular ring; channel accessible relatively satisfactorily. For this is the window for channel I, at same height, slightly narrower than the window for channel II and the two opposite pull tabs on the mounting pot are somewhat out of the, at an angle of 90 Degree to the line of symmetry in which channels I and II lie opposite one another Symmetry line inserted twisted.

The one with the two flange O-ring seals on the opposite windows the central tube sealed channels I and II are each outside the circular channel  angled by 90 degrees, running parallel to the overflow pipe feed and drain pipe from the encapsulation space, running parallel on both sides, also to the rear in Run towards the back of the bathtub wall on the foot side. The two themselves opposite windows, or the groove for their seals and the analog Transitions over the circular ring channel can be realized by spraying since one Seal carrier with subsequent transfer over the circular ring channel and again then angled 90 degrees into the drain housing upper part as a separate part is sealed. Where a conventional overflow pipe has 98 degrees of offset upward Forward to the Ablautkopf at the overflow hole is a box in which the Bathtub water drainage channels I and II for forwarding to the communicating tube and be combined again to form the actual whirlpool extraction nozzle. This Box also includes 98 degree redirects for overflow and additional Discharge pipe after the additional introduction under the drain hole into the siphon of the set.

According to the invention opens into the lid of the channel I and II summarizing bathtub water drainage box from Fig. 2, 3a, 3b and 3d in vorst. Note 199 58 312.9 can be seen mixed water downpipe for soil inflow.

If via the intake manifold, bathtub water via the drain hole of the tub Whirlpool pump is sucked in, the tub overflow can be communicated Tube that, like the intake manifold, from which the bathtub discharge ducts I and II summarizing box, is no longer working, so here remains the conventional overflow at drain hole open. The at, for non-intake manifold design but only bottom inflow combined with overflow provided at the drain hole communicating tube also remains when using the whirlpool and according to the invention the dry-running protection sensor of the whirlpool is attached to the communicating tube.

The advantages achieved by the invention are, in particular, that Set with integrated whirlpool intake manifold and relatively small overall height placed under the bathtub and the set has a plug actuation, which ensures that if in the connecting line leading to the circulation pump This negative pressure does not result in the opening of the sealing plug.  

The spindle drive, which is preferably used to pull the stopper, is one Remove this with the stopper and its sealing seat over the drain hole towards the tub possible. The good access to the odor trap thus given also favors this Visibility and thus maintenance of the additional discharge discharge on the one hand Encapsulation space of the free flow section to secure the mixed water bottom inflow and on the other hand from the drain funnel under the hydraulic three-chamber System separator to protect the spa disinfection.

The constructive, more complex fitting structure at drain hole diameter 52 by means of two concentric pipes in the symmetry line of the drain hole enables the bath water drainage channels I and II for intake manifolds and communicating pipes and the two inlets overflow pipe and additional drainage under D2 = 52 to be arranged on the same level, with which the additional So-called "visible" introduction relatively just below the drain hole and can still be reached from the bathtub even with D2 = 52. Due to the opposite, approximately rectangular exit windows to the two opposite bathtub water drainage channels I and II in a horizontal plane, a large exit cross section is possible with a low overall height. When the sealing plug is open, it can be flowed around well in the area of the two opposite exit windows when the bath tub is drained, in addition to the circular channel that is formed.

The 98 degree angle deflection box in the behind the bathtub wall on the bottom Bathtub water drainage channels I and II are hydraulically combined here the mixed water down pipe coming from the drain head at the overflow hole as the bottom inflow initiate.

If with whirlpool intake manifold, floor inflow and conventional overflow at Overflow hole the communicating tube that is actually designed for non-whirlpool, only floor inflow and overflow provided at the drain hole (kit) can be left the dry-running protection sensor of the whirlpool is arranged on the communicating tube become. This sensor is then also a hair suction protection (TÜV). If that Drainage hole in the tub and the tub plug, because by means of spindle The drive is pulled, cannot be sucked up, via the communicating tube  and or air is sucked in via the bottom inflow mixed water downpipe, or the The sensor on the communicating tube will immediately switch off the whirlpool pump.

In the priority note. 09.02.99 199 05 132.1 it had still been assumed that a fill stop float as with the Geberit-Clou would also be required if the overflow at the drain hole of bathtubs is due to hygiene reasons. Since the sink according to the above-mentioned patent DE 40 32 404 on the market, bath tubs are also fitted with a fill stop float and on relatively complex versions of the mixed water floor supply, such as these. B. from FIGS. 6a and b OF DE 198 40 913 A1 can be seen. The concentric tubes ( 12 , 14 and 23 ) in the line of symmetry ( 36 ) of the drain hole ( 2 ) have only one purpose, especially since it has been found that lower bathtub entry heights are very well received, a drain fitting for D1 = 52 +3 | -2 with the lowest possible height under the tub, with, in particular, intake manifold ( 57 ) for the whirlpool with the largest possible bathtub water outlet cross-section, above the lowered sealing plug ( 18 ) with the one with the concentric tube ( 12 , 13 ) one-piece, also via the overflow hole ( 2 ) to the tub removable sealing seat ( 17 ) to achieve; in one piece with the concentric tube ( 12 ), its slightly conical lower part ( 13 ) and in particular its bottom ( 16 ) is also the centrally arranged guide bush ( 64 ) for the preferably spindle-stroke adjustment of the sealing plug ( 18 ); please u. U. also Fig. 2a and b 199 50 298.6. Due to the concentric pipes ( 12 , 14 and 23 ) it is possible that the opposite bath water discharge window ( 15 , 15 °) with the inlets ( 31 ) of the overflow pipe ( 28 ) and ( 27 ) of the additional drainage ( 28th ) at the same height, the windows ( 15 , 15 °) to the central tube ( 14 ) and the discharges ( 27 and 31 ) into the circular ring channel ( 33 ) on the vertical part ( 5 ) of the top part ( 1 ) can be arranged . With the seal ( 19 ), the horizontal channel ( 22 ) leading over the circular channel ( 33 ) to the window ( 15 ) and with the opposite seal ( 20 ) is the analog channel ( 22 °), with its seal holder ( 21 °), connected to the window ( 15 °, 14 ). The channels ( 22 , 22 °) are connected at right angles, also horizontally, with the channels ( 24 , 24 °) running parallel to one another. The channels ( 24 and 24 °) are expanded in the area just before under the foot-side bathtub wall ( 40 ) for inserting the corresponding counterparts on the connection box ( 53 ) by two material thicknesses. All bath tub water must always be able to drain completely to the open sealing plug ( 18 ) and thus through the odor trap ( 38 ). The odor trap water, the height of the horizontal channel ( 38 ) plus H = 50 mm barrier water height DIN EN 274, is just below the bottom ( 16 ) of the central pipe ( 14 , 12 ). The side-by-side discharges ( 27 and 31 ) are in the atmosphere. Air can be drawn into the encapsulation chamber ( 29 ) via the overflow head ( 58 ) via the overflow pipe ( 44 ), the inlet ( 27 ) and the discharge pipe ( 28 ).

The due to the concentric tubes ( 12 , 26 ) just below the drain hole ( 2 ) inlet ( 27 ), the backflow prevention not shown here, as already described in FIGS . 1b, c and e 199 50 298.6, is for The central tube ( 12 ) removed from the bathtub with its spindle drive ( 64 ) is relatively easily accessible. For this purpose, the flange O-ring seal ( 19 ), at the same height, is made less wide than the opposite analog seal ( 20 ). The pull tabs ( 10 ) can be seen as in section BB, which is not shown in the drawing in section AA, rotated somewhat from the center. Only through the two opposite seals ( 19 and 20 ) is it possible to guide the two pull tabs ( 10 ) in the area of the central tube ( 14 ) downwards, below the bottom ( 16 ) thereof. The threaded bushes ( 62 ) for the two M4 fastening screws, not shown, threaded through the screw guides ( 11 ) are inserted into the lower part of the drain fitting.

When fitting for D2 = 52, the mounting pot ( 7 ) with its two pull tabs ( 10 ) replaces the three M5 screws ( 61 ') and the flange ( 68 ') of the D2 = 90 version shown in Fig. 4. The central tube ( 12 ) with its bottom ( 16 ), in which the sealing seat ( 17 ) for the sealing plug ( 18 ) and its spindle drive, its guide bush ( 64 ), is connected at the bottom by means of ribs on the bottom ( 14 ), can be removed towards the bathtub with the O- Ring ( 13 ) in the cylindrical part ( 12 ) of the mounting pot ( 7 ) sealed. Not shown in the drawing is a locking device which presses the central tube down completely, on the one hand to ensure that the two window seals ( 19 , 20 ) function properly towards the edges of the windows ( 15 , 15 °) or the slightly conical part ( 14 ) of the central tube and, on the other hand, to ensure a perfect coupling of the drivable threaded spindle ( 66 ) to the triangular drive pin ( 67 ) in the lower part of the fitting ( 37 ).

Because of the residual water discharge ( 71 ) from an air system whirlpool and a minimum distance from the underside of the bathtub floor after the barrier water level, which is just below the sealing plug ( 18 ), the height of the drain set under the tub cannot be less than 115 millimeters .

In the cylindrical part ( 6 ) of the waste set ( 1 ), h2 = 6 to h2 = 16, EN 232 can be compensated. In the fully inserted position of the cylindrical part ( 12 ) of the mounting pot ( 7 ) shown in section AA, this will move to protect the window seals ( 19 , 20 ) against a stop (not shown). With the central pipe completely pulled out, apart from the smaller drain hole D2 = 52 to D2 = 90, the mounting pot ( 7 , 12 ) = 47.6 compared to the 90 version, Fig. 4, for reaching through after the odor trap ( 38 ) only after the two M4 fastening screws or their guides and contact surfaces ( 11 ) are disruptive.

The O-ring ( 13 ) and the double-sided window seals ( 19 , 21 ) do not have to be as tight as the sealing plug, ie maximum pressure H = bath water level.

Fig. 1e shows how the above vertical part ( 5 ), under D2 ( 2 ) part of the upper housing part ( 1 ) of a horizontally divided drain fitting structure as in vorst. GM can be described; here only the angle can be rotated 90 degrees ( 39 ); Please also see the following Fig. 4 version D2 = 90.

Fig. 1f shows how the above vertical part ( 5 ), in a conventional embodiment, is also rotatable.

Are the FIGS. 2a-d, the hydraulic connection box (43) in which the data coming from the Ablaufgamitur upper part (1) bath water channels I (24) and II (24 °), under the tubs floor, behind the rear side the foot-side bathtub wall ( 40 ) can be combined again, integrating the 98 angular degree deflections ( 46 ) of the overflow pipe ( 32 ) and the additional drain pipe ( 28 ) into the box ( 43 ), in one piece with this.

The connection box ( 43 ) is closed at the top by means of the cover ( 49 ), with the vertical or 8 degrees of angle (foot-side bathtub wall ( 40 )) connecting pieces for the overflow pipe ( 44 ) and drainage ( 47 ) being passed through the cover ( 43 ) and these passages z. B. by means of the bundles ( 45 ), as well as the lid itself, are ultrasonically welded all around the top of the box ( 43 ). In one piece with the cover ( 49 ) and thus discharged from the connection box ( 49 ), the communicating tube or its connecting piece ( 50 ) is introduced after the drain head ( 58 ) at the overflow hole ( 42 ) and the mixed water downpipe ( 30 ) , or its connector ( 51 ). The outlet of the connecting piece ( 51 ) for the mixed water into the connection box ( 43 ) is the mixed water ( 30 ) floor inflow ( 52 ) to the bathtub. Not shown at the outlet or inlet ( 52 ) is a floating backflow prevention similar to the Geberit-Clou fill stop float, as can be seen from FIGS . 6a and b and the RV from FIG. 8 DE 198 40 913 A1, please first. Fig. 8 claim 8. Not shown in the drawing is also at the outlet, or introduction of the communicating tube ( 50 ), an aperture that a u in whirlpool bath water suction on the suction nozzle ( 57 ). U. required Pit®trohr effect, also similar to a pitot tube as with a Hall speedometer for kites, generated; for this, please refer in particular to 3d and flow arrows in FIGS. 2a and b below. If the above is required, this will also be analogous to the mixed water inlet ( 52 , 51 ); a fill stop RV is then no longer possible. The box ( 43 , 49 ) cross section in its sections CC and DD is designed so that the cross section of the BW channel II, despite the angle 98 degrees ( 46 ) and despite the 98 degree deflection of the additional derivative ( 56 , 48 ) , can be transferred to the communicating tube ( 50 ) and the intake manifold ( 57 ). Also not shown in the drawing on the box ( 43 ) is the ( 73 ) inlet after the overflow pipe ( 55 , 46 , 44 ) for emptying residual water in the air system whirlpool, in principle also in the following Fig. 34.

Piping pictures Fig. 3a-c

The hydraulic connection box ( 43 ) and 98 degree of curvature, arranged in height under the bathtub floor ( 41 ) and there behind the back of the foot-side (or also one of the side) bathtub wall ( 40 ), between this and the tile covering of the tub, connects the two with a hydraulic connection Drain fitting, or its upper part ( 1 , 5 ) and the drain head ( 58 ) on the overflow hole ( 42 ). In the connection box ( 43 ) the BW channels I ( 24 ) and II ( 24 °) are redirected and deflected by 98 degrees in the communicating tube ( 55 , 49 ) to the overflow space in the drain head ( 58 ) or in the intake manifold ( 57 ) derived. The overflow pipe ( 44 ) led out of the overflow space in the drain head ( 58 ) passes through the box ( 43 ), deflected by 98 angular degrees ( 46 ) and is raised in height under the tub floor ( 41 ) by means of the horizontal piece ( 55 ) with the corresponding overflow pipe piece ( 32 ) connected to the drain fitting and thus in the introduction ( 31 ) via the circular ring channel ( 33 ) to the odor trap ( 38 ). Analogously to the above, the discharge pipe, for. B. a spiral hose with a smooth inner wall, from the encapsulation space ( 29 ) of the free flow path ( 30 ) at ( 48 ) to ( 47 ) on the box ( 43 ) and in turn angled by 98 degrees in this, via the horizontal drain pipe connector ( 56 ) and the pipe of the additional discharge line ( 28 ) is introduced into the circular channel ( 33 ) at the inlet ( 27 ). The coming at bottom inflow from the free flow path ( 30 ) via the mixed water downpipe described in 199 58 312.9 is connected to the mixed water downpipe connection ( 51 ) to the cover ( 49 ), or the hydraulic connection box ( 43 ) and enters the connection box ( 43 ) at the so-called bottom inflow ( 52 ); The mixed water passes from the box ( 43 ) via the BW channels I ( 53 ) and II ( 54 ), which in the extensions ( 34 , 34 °), which are shifted upwards by two material thicknesses, into the corresponding BW channels I ( 24 ) and II ( 24 °) are inserted into the drain fitting ( 1 ), with the drain plug ( 18 ) closed, through the windows ( 15 , 15 °) into the central tube ( 14 , 12 ) and thus through the drain hole D2 ( 2 ) in the bathtub ( 41 ), see s, b. Flow direction arrows in Fig. 3c.

Junction box ( 43 ) at the connection piece ( 50 ) connected communicating tube, which opens at the outlet edge ( 59 ) into the overflow space of the drain head ( 58 ) used in two completely different ways. In the case of non-whirlpool tubs, preferably with a floor inflow ( 52 ), for tub overflow ( 59 ) at drain hole D2 ( 2 ). The overflow hole D1 ( 42 ) is then closed.

In board Fig. 3a-c, the position numbers are given without, although the so-called. Pipework also apply fully to FIGS. 4a-d.

In whirlpool baths with a water system whirlpool, in which the BW channels I ( 24 ) and II ( 24 °), also combined in the box ( 43 ), primarily lead to the suction port ( 57 ) and thus to the suction side of the whirlpool pump, it offers to remain on the communicating tube ( 51 , 59 ) provided by the modular system, despite the conventional overflow that is absolutely necessary in the whirlpool, via the overflow hole D1 ( 42 , 44 ) and to arrange the dry-running protection sensor ( 74 ) of the whirlpool on this. From the schematic diagram of FIG. 3d it can be seen how the communicating tube and also the mixed water downpipe are connected hydraulically to the bathtub water suction, Bernulli. If theoretically, at z. B. worn cover ( 69 ') over the drain hole ( 2 , 2 ') someone holds it by hand, this is extremely problematic, the hand can hardly be removed when the pump is switched on, at least bruises can be expected. It should also be borne in mind that lateral suction is popular as an alternative to the drain hole ( 2 , 2 '). EN60335 / 2/60, or identical to DIN VDE 0700, therefore prescribes: "Whirlpool devices must be constructed in such a way that no hair can be pulled into openings due to the suction effect of the water if this could lead to a danger". A larger intake cross section, such as this. B. u. U. could be given with a drain hole diameter of 90 mm, theoretically (continuity) the flow rate would be reduced nevertheless the fact remains that the above hair suction test severely constricts the manufacturers of whirlpools.

In the case of the communicating tube present in the modular system, it would also not be problematic since this, or its outlet edge ( 59 ) in the overflow space of the drain head ( 58 ), is optimally “dewatered” if, as already mentioned above, pitot tube-like (Hall speedometer) coverings ( 76 ), water could spurt out at the top under certain operating conditions. If the sensor ( 74 , 74 ") were not the same with which a certain or generally the water level in the tub is controlled, the hair suction safety sensor ( 7 ) could also be attached to the mixed water downpipe. As with Fig. 3d (Bernulli) shows that if the drain hole ( 2 , 2 ') is closed while the pump ( 75 ) is running, air is sucked in immediately via the communicating tube, which is connected to the atmosphere in the drain head ( 58 ), the sensor ( 74 , 74 ") will switch off the pump immediately.

Fig. 2e shows the connected to the drinking water ( 81 ) hydraulic three-chamber system separator ( 80 ) for fresh water ( 82 ) after disinfection of the air system or combination whirlpool arranged above the integrated drain funnel ( 83 ) in a special version.

Fig. 4a-d

The drain set shown here for D2 = 90 is that in vorst. GM described in detail in the set of the spindle drive of the sealing plug ( 18 '), the triangular drive pin ( 67 ') with its actuation, as is also preferably the case with the above set for D2 = 52, via the overflow hole D2 ( 2nd ') can be removed towards the bathtub, the fittings of FIGS. 4a-d additionally, in one piece, with the drain fitting housing upper part ( 1 ') above the lowered sealing plug ( 18 '), the two BW channels I ( 24 ') and ( 24 ') as a bathtub water drain to the communicating tube ( 50 ) and or to the intake ( 57 ) for whirlpool. This connection ( 57 ) can, as with the set of the previous Fig. 1a-f, a greywater connection, to a greywater reservoir for z. B. toilet flushing. Compared to the GM set on the market, the additional inlet ( 27 ') of the discharge line ( 28 ') from the encapsulation chamber ( 29 ) is provided and the inlet ( 31 ') of the overflow pipe ( 32 ') is towards the lower edge of the drain hole ( 2 ') set higher. Thus, the two discharges ( 27 ', 31 ') are connected to one another in the air with certainty above the level of the odor trap water in order to U. As also described above, to be able to suck air into the encapsulation space ( 29 ). With the fitting according to GM, the overflow pipe is introduced into the sealing water. Here the set of Fig. 4a-d is also changed. The O-ring ( 71 ) with which the sealing valve seat ( 17 ') for the sealing plug ( 18 ') in the upper part ( 1 '), removably sealed, is laid just below, below the sealing plug ( 18 ') and up there is no longer an annular segment inlet chamber for the overflow pipe ( 32 '). The so-called dip tube of the GM is only attached to a ring ( 63 ') on which the guide bush ( 64 ') for the spindle drive is still attached, by means of ribs (not shown).

In the whirlpool water system in combination with the air system, a residual water drain ( 71 ) is also required for the intake, see B. above Fig. 2b and d and 3e. With the air system, it is considered an advantage if the discharge of the residual water is in the atmosphere. The opinions of the experts in the Ablaut area are divided. The whirlpool gentlemen share the opinion that is called for pipe cutters, here in particular type 3, 300 millimeter long, vertical, ventilated section, "to prevent the migration of bacteria". After the partition of the standard version has been eliminated, the introduction ( 31 ') of the overflow pipe ( 32 ') and thus also the introduction of the residual water emptying into the atmosphere.

In particular because of the similar to Figs. 1a-f side by side and higher discharges ( 27 ', 31 '), additional drain pipe ( 28 ') and overflow pipe ( 32 ') after the siphon ( 38 '), the two-sided design of the is preferably Maintain BW channels I ( 24 ') and II ( 24 °).

The injection molding, since no window seals ( 19 and 20 ) are required, easy to manufacture in one piece with the upper part of the set ( 1 '). Channels I and II cut the large cylinder ( 60 ') on which the collar ( 4 ') for the seal ( 3 ') is on both sides at the openings ( 71 ) and so the bath tub water can be led out over the plug ( 18 ') to the hydraulic connection box ( 43 ). The piping diagrams of the preceding Fig. 3a-e, with their description are fully transferable to the set D2 = 90.

All of the features disclosed are (in themselves) essential to the invention. In the revelation of the Registration is hereby also the disclosure content of the associated priority documents fully retracted, also for the purpose of including the characteristics of these documents To include claims of the present application.
