DE10247441A1 - Bath overflow and backwash preventer system centers round top horizontal twist grip with divider cartridge housing lowered along with downcomer pieces - Google Patents

Abstract

The easily exchanged divider cartridge is lowered along with its vertically descending pipes (2-4), notably mix water in and outpipes, and pipe (4) from the relief valve (22) outlet and connected to the plug connections (54,55) to be installed in the horizontal bore (16) in the top rim (7) of a conventional bath. Thus the lower part of the cartridge outside diameter equals the bore (16) diameter less than twice the thickness of the overflow head (43) hollow fixer screw (52) and the rotary cylindrical driver (79) plus the gap used to draw air into the communicating pipes (76,77) as hair guard. The horizontal grip (32) bore (16) plane of symmetry is clamped via ribs (35) between the cartridge housing cover (30) and the diaphragm chamber cover (27).

Description

The invention relates to a horizontal Bathtub inlet and overflow set, with horizontal, relatively very low rotary handle for actuating the tub plug, on a flush top Bathtub edge wall, the mixed water supply to the bathtub, and their protection against back suction of bath water below the upper edge of the bath and here the tub overflow by means of a communicating tube he follows.

Intrinsically safe, horizontal bathtub inlet and overflow sets are no longer available DE 100 38 246 A1 and DE 101 07 671 A1 known.

In the DE 100 3 8 246 A 1 Under the horizontal bore and under the, relatively very low, usual horizontal twist grip, the free flow path for protection against back suction of bath water is considered problematic by some experts, because bath water is always used as overflow water in its encapsulation space or in between The back of the bathtub and the tile covering underneath the free flow section are drained. No aerator can be connected behind the free flow section, which is a special A1 pipe interrupter with 20 degrees of deflection. For the set after the DE 101 07 671 A1 Since, instead of the free flow section, a miniaturized hydraulic three-chamber system separating device, back pressure can be built up behind the protection (P ₁ >Pi> P ₂ , please, under certain circumstances DE 44 39 050 C2 ). In order to be able to do without a drain funnel for the three-chamber device or its relief valve for emptying the central zone, the horiz. Stopper twist grip must be at least 35 mm high, in the worst case this could be called a testicle catcher.

If you do not want to exceed this height, it will be difficult to find a construction that allows the use of commercially available backflow prevention inserts, P ₁ > Pi and Pi> P ₂ . In both, in front. In the published communication, the communicating tubes, despite the plastics that are present today with minimal adherence, could be regarded as not unproblematic as possible contamination by bath water residues.

Main objective of from the 2a . b . c and d DE 101 07 671 A1 The set to be seen can be dispensed with a drain funnel between the back of the bathtub and its tile covering. Constructive newer considerations for the possible rejection after a com., Also with drain sets with a construction height of only 90 mm under the tub. Tubes and an easily accessible additional inlet with easily maintainable backflow prevention were at vorst. Considerations not yet taken into account. In this context, those in the 1b . 2 and 5a in DE 100 38 246 A1 proposed rejections after a com.

tube at z. B. a whirlpool side suction less interesting.

The specified in claim 1 Invention, the problem is based on a horizontal twist grip with a construction height, as usual with only overflow sets, for tub sealing plugs OPEN / CLOSE, on a flush upper edge of the bathtub a commercial one Bathtub, with additional brought in horiz. Bore approx.? 52, under this a hydraulic three-chamber system separator with commercially available Backflow prevention inserts, part to sink.

The invention has another problem based on the required drain set, for in particular a drain hole 52 +3 / 2, with a height of 90 mm under the tub, to be designed in such a way that the clothing, over a lowered sealing plug, a diversion after a com. Tube and an easily accessible additional Introduction, with well maintainable backflow prevention, for the Derivation from that required when the system separation is recessed Has a funnel.

 After further training in Invention addresses the problem of possible bath water residue the walls of the com. tube solved by appropriate training of the mixed water soil inflow.

These problems are solved by the in Claim 1 and 2 listed Features solved.

In order to simplify the production separation of the system separation cartridge, commercial RV inserts are used, preferably for the pre-pressure side P ₁ > Pi and the back pressure side Pi> P ₂ . These, RV's are parallel next to each other, horizontally under the horizontal control membrane in the line of symmetry of the horiz. Stopper twist grip and the horiz. Tub edge bore? 52 vertical relief valve, for emptying the central zone, arranged and partially countersunk in the cartridge housing in the bore? 52. In the cartridge housing there are two angles of 90 degrees for deflecting the mixed water, P ₁ and P ₂ , which are fed to the cartridge by means of vertical tubes. In the overflow head under the tub rim are three sealed hydraulic plug connections: mixed water P ₁ to, P ₂ from the cartridge and discharge of the outlet from the central zone to the drain funnel arranged next to the drain head, this discharge through an angle of 90 degrees and the horizontal one connected to it Rejection via which P ₁ and P ₂ plug connections are rejected from the overflow head. The process funnel between the back of the bathtub and its tile covering is preferably as in DE 199 50 302 A1 proposed, trained. When the relief valve is open, the middle zone of the cartridge, including the reclining RVs, can leak completely (W / TPW 135, SVGW).

At the overflow head there are connections for pressure-hoses with metal mesh cover for mixing P ₁ and mixing P ₂ from the cartridge. The drain P ₂ can also in the overflow head directly after the com. Tube.

The horiz. Rotary handle for plug actuation is preferably a ring that only runs around the outside of the system separation cartridge, is rotatably supported on the ring and clamped between the housing and the diaphragm chamber cover. On the underside of the overflow head is, in a known manner, outside the overflow space, in the line of symmetry of the tub rim bore, the gear that pushes the rack back and forth to actuate the Bowden cable for plugs OPEN / CLOSED. Instead of the gear and the rack, solutions with levers are also known. The overflow head is fastened at the bottom to the flush, bath tub edge with a through the horiz. Bore ϕ52 threaded banjo bolt, with the largest possible inside diameter, in which the cylindrical driver is rotatably mounted to transmit the rotary movement from the plug twist grip to the gear wheel of the rack. The cartridge housing is partially recessed in the inside diameter of this driver and partially recessed in the tub rim. The storage of the cyl. Driver on the outer diameter of the cartridge housing would also be possible. The cyl engages in the overflow space of the overflow head. Driver in the, slightly above the height of the sealed plug connections P ₁ and P ₂ horizontally arranged, rigidly connected to the axis of the rack and pinion drive bar. The cyl. Carrier, with its horizontal collar, over the tub edge, is all-round with slots that are as large as acceptable in terms of strength, so that on the one hand the bath water in the overflow area from the com. Drain the pipe after the overflow pipe and on the other hand the driver can still be turned into a sufficiently large angular range despite the horizontal rejection to the drain funnel.

With the horizontal overflow using the com. As is the case with fittings with a horizontal overflow on the market, the tube is 14 and 10 Epo 388 512 A2, page 15, lines 45, 50) known a 3 cm higher water level. One of the sets on the market on a lowered tub edge section is combined with a so-called super-flat drain, which allows a further 3 cm more bathing depth, see please 5 ; this super flat drain according to GM 298 23 01 is for a 90 hole and has neither a rejection after a com. Tube after an introduction for the derivation from the drain funnel of the system separation device.

On the, as a molded part, the drain fitting upper part, which is open at the bottom, is at the usual distance of approx. 80 millimeters of the two vertical lines of symmetry for fittings for a 52 tub drain hole, the connection with its seal holder, after the bathtub drain hole underside , D ₂ = 52 +3 / 2, and the horizontal outlet from the odor trap after the drain pipe on the building side. Because of the 90 millimeter height under the tub, the outlet is horizontal, as well as from above. GM to see trained. The relatively high-build sets with vertically welded odor traps on the market are likely to go back to the higher sealing water heights previously prescribed than the 50 millimeters that can now be taken from EN 274 page 11, table 5. It can also be assumed that once the view has passed, the overflow pipe should be introduced above the sealing water. The connection of the drain hole connection and the horizontal outlet in the housing is designed in such a way that when the immersion tube is removed, from the bathtub, the odor trap outlet side is quite accessible via the drain hole. Therefore, the 50 millimeter barrier water height would not be reached without a replacement pipe, contrary to the vertically welded odor traps. In the upper part of the housing, the cylindrical sealing point for the removable immersion tube is placed so far down that just under the sealing seat, in the immersion tube, the sealing water is for the sealing plug. Even with a construction height of 90 millimeters under the tub, it is possible above the immersion tube sealing point with an oval cross section of bath tub water above the lowered plug after a communicating tube for tub overflow and, in the case of a whirlpool, also hair suction protection (claim 1 DE 100 38 246 A1 ) to divert; there can also be a mixed water flow into the soil. According to the invention, in the same height section, above the sealing point of the immersion tube, the two channels, which are inclined downward by approximately 60 degrees, for the two M4 fastening screws of the band drain fitting fastening according to the invention, described in more detail below, are led out. In the same height section there is also the blocked access to the additional inlet, with its backflow prevention flap, as is known from washing machine connections on the washbasin siphons. For the introduction of the overflow pipe and the additional introduction of the discharge from the drain funnel and or the hose box ( DE 199 60 818 C2) the sealing water height is reached with, like the immersion tube, downward-reaching walls on the upper part of the housing, which form two separate immersion chambers for the discharge into the sealing water.

On the waste set housing upper part, around its horizontal outer contour, below, ho welded horizontally on the case back. In the 90s drain hole set to the front. GM compensate for the three vertical fastening screws of the bathtub material thicknesses and if a whirlpool suction nozzle is used to discharge the bath water over which the closed, lowered plug is installed after a whirlpool pump, longer screws are used. Two rectangular channels are connected to the left and right of the cylindrical shafts for the two M4 fastening screws that are inclined downwards at an angle of approximately 60 degrees. On the mounting flange on the side of the tub, two steel bands are dotted opposite each other. A so-called tensioning particle is punctured at each of the two ends of the band opposite the flange underside, with the band-point arm adjoining the through hole for the fastening screw on the left and right. The two fastening screws can thus be outside the cylindrical space under the drain hole seal and above the sealing point of the dip tube. The smallest diameter of the tub drain hole,? 50, is only reduced by 2 × the material thickness of the tapes when the set is attached; this, or very slightly smaller, is also the immersion tube sealing and thus, when the immersion tube is removed, the access diameter to the odor trap or to its outlet side. The two M4 fastening screws that can be screwed into the downward and outward-sloping channels and that pull the ribbons into the channels diagonally downwards to secure the trim set can compensate for the 8 mm tub material thickness. If a whirlpool intake is to be set up, a flange with longer bands is used.

A floor inflow is unsuitable for washbasins. Tubes for their overflow at the drain hole (possibly here here 2a above), any pool water residues could therefore be viewed as a problem, which is why with Geberit / Keramag Clou fill stop floats.

In the communicating tube of the single over and invention The waste set is preferably the mixed water shower head-like, over the whole com. tube distributed, with z. B. 64 holes with ϕ1.2 as known from shower heads, introduced into this. An advantageous embodiment is an extrusion profile for the kom. Tube, with the all around the actual com. Tube of mixed water are led can. From this oval, circular channel-like mixed water channel the mixed water over the showerhead-like spray nozzles, after inside, after the com. tube guided. With the shower head-like introduction of the mixed water, as a soil inflow, in the comm. tube this will be before filling and after draining the tub, each hosed inside. Usually the tubs are rinsed with the hand shower after draining; in front If the bath / shower diverter is pulled, there will always be a shower the com. Tube.

The advantages that can be achieved with the invention are, in particular, that if the problem with securing by means of a free flow path is eliminated, even when using the partially recessed hydraulic three-chamber system separating device in the horizontal hole in the flush upper bathtub edge of a commercially available bathtub horizontal stopper twist grip does not extend above the upper edge like the usual vertical twist grip on conventional ONLY overflow fittings. Due to the mixed water floor inflow above the more expensive sealing plug of the drain fitting according to the invention for preferably a drain hole D ₂ = 52 +3 / 2, with a construction height of only 90 millimeters under the tub, there is also no one under the upper tub rim for comfortable bathing for two - and swivel-out mixed water inflow more required. Except for the drain hole, there is nothing left in the tub or on its walls.

Except for one eye in the tub-side cover, there is nothing to be seen of the inflow of the floor to make any dripping water visible if the fitting is not properly switched off (possibly please see) 7a . 8th , Line 65, 9, line 5 in DE 100 38 246 A1 ).

Due to the inflow of soil on the one hand by the shower head-like over the entire length of the kom. tube distributed mixed water introduction the possibility of possible bath water residues at the interior walls the com. Tube, to spray before and after each bath and on the other hand this inflow less noise and steam development.

For the horizontally below the horiz. Twist grip arranged side by side Check valve of the Three-chamber cartridge can standard zip inserts used become. That in the line of symmetry of the horiz. Twist grip and the horiz. Bore in the tub edge relief valve, the cartridge must hydr. not be balanced and is just one on the horiz. Control membrane sealing cone attached below.

The cartridge is very easy to replace by means of three, P ₁ to, P ₂ and channel outlets from sealed plug connections in the overflow head.

The problem of initiating the Derivation from the drain funnel for the relief valve for emptying The middle zone of the cartridge is easy to maintain with RV on the waste set according to the invention significantly reduced.

In modular design, with convertible injection molds, possible parts 1 and 2, the system separator cartridge is on the one hand, with a vertical, central relief valve also for horiz. Sets with overflow by means of a lowered tub edge section and, on the other hand, with a non-centric one, by means of a lever from The relief valve operated by the control diaphragm can also be used for conventional, vertical inlet and overflow fittings in front of a vertical overflow hole D ₂ = 52 +3 / 2 in a tub wall. The horiz. Overflow head must, for technical reasons, because of the 90 ° deflected, then horizontal drainage from the overflow chamber from the relief valve outlet, or its hydr. Plug connection, after the outer drain funnel, be in two parts, heat or ultrasonically welded. The lower part, with its tooth rim and rack for the plug actuation, will be part 2 of part 1 overflow head for a conventional vertical fitting. On the welded board. Part with the horiz. Relief valve rejection is also the initiation of the com. Tube; Part 1 of this part is without this introduction and so for an overflow head for a horiz. Set on a lowered tub edge section.

According to a further embodiment of the invention, in addition to the overflow housing under the flush upper bathtub edge, contrary to the funnel which is clearly to be preferred, is out 1 DE 199 50 302 A1 to see a normal drain funnel as from z. B. known under pipe separators.

After further training in Invention is an analog drain fitting used for a 90s drain hole.

An embodiment of the invention is shown in the drawings and is described in more detail below.

The following is an explanation of the invention based on the drawings according to structure and also according to the mode of operation of the illustrated Invention.

The in the horiz. drilling 16 , in the flush upper edge of the bathtub 17 , or in the inner diameter of the banjo bolt 52 and the cylindrical driver 79 partially recessed hydraulic three-chamber system separator cartridge, housing 1 , is in the overflow head cpl. 43 , composed of overflow head lower 44 and top 45 , to the hydr. plug-in connection 54 , O-ring 56 , with their mixed water P ₁ feed tubes 2 , to the hydr. plug-in connection 55 with their mixed water P ₂ drainage tubes 3 and with their drainage tubes 4 from the relief valve outlet bore 5 at the hydr. plug-in connection 46 , O-ring 57 , connected. The cartridge is completely fixed against pulling off, in the line of symmetry of the horizontal. drilling 16 , is not shown in the drawing. The Zu-2 and drainage tubes 3 and 4 are in one piece with the cartridge housing 1 , On the cartridge is on the deposit 31 , on the diaphragm chamber cover 27 , the horizontal stopper handle 32 pivoted and axially between the collar 33 of the membrane chamber cover 27 and, over the ribs 35 , the screw base collar 30 , on the housing 1 , fixed.

The membrane chamber ceiling 127 is with the housing 1 , or with the screw base collar 30 screwed, with this on the membrane sealing collar 20 control membrane on top 19 is pressed. Instead of the screws 29 with good manufacturing experience, ultrasonic welding is also possible. Over the membrane 19 is the P ₁ room 36 , under the membrane chamber cover 27 ,

The P ₁ water comes from the tube 2 , or its transfer box 6 , via the control line 37 that are in the housing parallel to the control diaphragm 19 running control line 38 , the two holes 42 , the intermediate through hole 41 in the membrane 19 and over the control line 40 in the membrane chamber ceiling 127 among these. The control lines are as far as necessary with the plugging 39 locked.

For 90 degree redirection from the tube 2 , or its transfer box 6 P1 water is coming, at the weld 8th , on the box 6 Outlet or cartridges 1-floor 25 , the angle 90 degrees 9 welded. In the line of symmetry, parallel to the edge of the bathtub 17 , is in the angle 90 Degree 9 the pre-pressure backflow preventer 10 , P ₁ > Pi, with the O-ring 15 , used, its fixation in the exit of 9 not shown in the drawing. The RV 10 on the pre-pressure side is seen from above in one half of the theoretical circular cylindrical cartridge housing 1 , At the same height, parallel to the pre-pressure side RV 10, laterally offset, in the other half, the back pressure side non-return valve, Pi> P ₂ , 12 , which is behind this 12 emerging P ₂ mixed water over a, first 9 , analog, second angle 90 degrees 13 , with the RV entrance lid 14 , O-ring 15 , about the weld 8th ; over the transfer box 7 and that first. 2 parallel, P ₂ discharge tube 3 after the hydr. plug-in connection 55 is derived. Next to the level both RV 10 and 12 is in the ground 25 , the housing 1 , the cylindrical space 24 , in the bottom of which the horizontal relief valve 22 finish bore 5 is. Inside the vertical walls 18 , maximum outer diameter of the housing 1 , please see cylindrical driver below 79 and between the horiz. ground 25 , Fillets 26 Bottom on 24 , when drilling 4 and the horiz. Membranes 19 bottom is the middle zone Pi 11 ,

Between the vertical walls 18 is on the housing 1 under the membrane 19 above the all-round horiz. Wall connection after the membrane sealing collar 20 , In particular, since the cartridge can also be used in a modular manner on a conventional vertical inlet and overflow set in front of the vertical overflow hole D ₁ = 52 +3 / 2 in a tub wall is the membrane 19 oval. The use in the vertical set specifies the maximum possible width of the oval, since the middle zone must be able to run out fully. The greatest length of the oval 20 . 19 is given because the diameter of the stopper handle 32 should not exceed the usual 80 mm and here the inside diameter of the preferably circular handle 32 , also because of the driving ribs 34 , after the horizontal waistband 80 , at the cyl. takeaway 79 , should not become too small. The largest diameter of the non-rotatable diaphragm chamber cover may also be used for optical reasons 27 . 33 don't get too big. The maximum outside diameter of the vertical walls 18 must, because of the recess in the inner diameter of the cyl. follower 79 be a little bit smaller like this. In the whirlpool, air must be able to be sucked in for hair suction protection (claim 1 DE 100 38 246 A1 ).

The vertical fastening and connecting rod 21 , between membrane 19 and relief valve sealing cone 22 runs between the RV's 10 and 12 downward. With the sealing cone open 22 . 5 can, even with the horiz. RV's 10 and 12 leak all water from the central zone. The sealing cone 22 is contrary to the usual three-chamber device BA version, u. U. please 2 DE 44 39 050 C2 , hydr. not balanced, also the cartridge has no pressure measuring connections BA / CA! Always in the direction of opening the relief valve 22 pressing spring 23 is only symb. located.

The overflow head cpl. 43 is welded together from the lower part of the overflow head 44 , the part 2 of an overflow head of a conv., vertical, intrinsically safe inlet and overflow set in front of an overflow hole D ₁ = 52 +3 / 2 in a tub wall and the overflow head upper part 45 Part 2 here with introduction 76 the communicating tube 77 , is.

Part 1 without introduction for the com. Tube and such correspondingly lower, is on a horiz. Inlet and overflow set with horiz. overflow inserted by means of a lowered tub edge section.

On the overflow head top 45 is the screw-on part 50 , with its support for the seal 51 , e.g. B. screwed on. In the screw-on part 50 is the nut thread for those through the horiz. drilling 16 threaded banjo bolt 52 , with their tub side, about 16 , Federation 53 , With the banjo bolt 52 can, as in the hydr. plug-in connections 46 . 54 and 55 and with the cyl. takeaway 79 horiz. entrainment bars 78 , Tub wall 17 Differences in material thickness can be compensated.

In the bottom horiz. Wall of the lower part of the overflow head 44 , Part 2, is the sealed grommet O-ring 68 , and depository 66 in which the gear 69 -Axis 67 from the overflow room 74 after the room 72 for the gear 69 is diverted. The gear 69 moves in a known way in the room 73 , Rooms 72 and 73 interconnected and in one piece with 44 who have favourited The Rack 70 to actuate the Bowden cable for tub sealing plugs OPEN / CLOSE back and forth.

The space associated with the atmosphere behind the back of the bathtub and its tile cladding 72 is, against the ingress of building dirt, with the lid 71 locked. In the lower, horiz. Wall of the lower part of the overflow head 44 are the two, parallel to each other, opposite each other to the outside 44 extending two rectangular channels 58 and 59 , The canals 58 and 59 are, because of the maximum permissible throat of the (construction kit) conv. vertical set (dimension 55 EN 232, page 5, table 4) rectangular. When drilling 60 is the P ₁ tube 2, or its hydr. plug-in connection 54 from the rectangular channel 58 off, and analogously, P ₂ lead tubes 3 , hydr. plug-in connection 55 , Drilling 61 , in the rectangular channel 59 initiated.

On the overflow head top 45 is one piece with this 45 , the hydr. plug-in connection 46 , with its angle 90 Degree 47 and its horizontal diversion 48 , only symb. outside 45 welded-on 90 degree degree deflection part 49 , after about that, besides the overflow head cpl. 43 arranged, funnel 62 ,

The cylindrical driver 79 is preferably in the inner diameter of the banjo bolt 52 rotatably mounted. The the axis 67 and so the rack and pinion 70 gear 69 twisting horizontal carrier bars 78 can be between the tubes 2 and 3 be rotated back and forth in a sufficiently large angular range and is from the lowest end of the cyl. follower 79 , or u. U. only its two fingers, twisted. Above the bathtub waistband 53 the banjo bolt 52 , until after under the horiz. Plug-turning handle 32 pulled up, is at the top of the cyl. takeaway 79 whose horiz. Federation 80 , or also only fingers, on the inside of the twist grip 32 driving ribs located 34 the rotation of the handle 32 after the racks 70 - tooth edge 69 is transmitted.

Mixed water flow: From the outside of the rectangular channel 58 on the overflow head lower part 44 welded connection 65 for a pressure hose covered with metal mesh, the P ₁ mixed water coming from an external mixer flows through the sewer 58 and the exit hole 60 after the hydr. plug-in connection 54 and so on the tube 2 and over the angle 90 degrees 9 ahead of the non-return valve on the pre-pressure side 10 , P ₁ > Pi, and enters the central zone behind it 11 on. About the hole in the lid 14 the Pi water enters the RV 12 on the back-pressure side and is then behind it as P ₂ water over an angle of 90 degrees 13 , the weld 8th , the transfer box 7 and the drain tube 3 after the hydr. plug-in connection 55 derived. Over the hole 61 the P ₂ water flows into the rectangular channel 59 and to its outlet connection 64 , on, on the connection 65 For example, a pressure hose for P ₂ mixed water with a metal mesh cover is connected after inflow of soil; at z. B. shower head-like introduction of the mixed water 131 . 133 into the communicating tube 130 is board connection 64 with connection 132 Figure 2a connected.

One-piece with the waste set upper part 81 are the overflow pipe connection 83 who have favourited Vertical Wall 91 , to form the chamber required for 83 because of the height of the barrier water 90 , the bottom, above the horizontally welded bottom 82 emerges from the vertical wall 93 , as before. Formation of the tubular chamber 92 , the channel inclined downward at an angle of about 40 degrees 97 , the oval rejection 127 for a communicating tube with its connection 128 , the two opposing cylindrical shafts inclined at an angle of approx. 60 degrees 105 , with their rectangular channels adjoining on the left and right 106 , for the two M4 screws of the band according to the invention 108 Fastening the set, the cylindrical immersion tube sealing point 89 and the horizontal exit 84 , after connection 85 or after the drain pipe on the building side. With the dip tube removed towards the bathtub 86 with its O-ring 88 , is in the odor trap water, in the drain fitting housing 81 and 82 a relatively large amount of space 87 to from the tub over the dip tube seal 89 after the horiz. exit 84 for cleaning. From the cylindrical space under the tub drain hole or under the seal 103 and over the dip tube sealing point 89 are derived from this, the shafts 105 and 106 for strap attachment, oval rejection 127 after the communicating tube and the channel 97 , with its constipation 101 closed access hole 102 after the additional introduction 94 with their, on their system 99 sealing non-return valve 100 , In the top part of the set 81 is in the chamber 90 the axis 120 with the lever located in the odor trap water 119 for plugs 113 . 115 pen 116 , Confirmation. Sealed on one side from the chamber 90 derived axis 120 is on the outside of the housing 81 , a lever in a known manner 121 which is pushed back and forth by the Bowden cable of the plug actuation. An alternative solution 122 is in 4b shown. The actuating pin 116 on the stopper 113 can through the jack 117 be guided, with the plug being closed 113 by means of the spring 118 , e.g. B. in whirlpool, possible.

On the bathtub mounting flange 112 , on which also a not lowered plug 115 , alternatively to the lowered one 113 sealing point 114 , possible, are opposite, below, the two fastening stainless steel bands 108 spot-welded. The, each, two opposite ends are each on the two point arms 111 , the clamping parts 109 , with their through holes 110 , for the two M4, e.g. B. Allen fastening screws 107 spot-welded. As an alternative solution to the bottom of the flange 112 dotted ribbon 108 It is also conceivable that the flange and ribbon are a part of the material thickness of the ribbon 108 and this part is lined or reinforced in the flange area by a stamped part, similar to 112. In the two sealing plugs 123 that below the channels 105 and 106 the M4 thread inserts are tightly closed 124 , One-piece with the sealing plug 123 are two belt deflection ribs each 125 over the, the tapes running vertically downwards 108 according to the channels 106 , to pull in the ribbon 108 about the chips 109 and the mounting screws 107 , Threaded bush 124 , in the channels 105 . 106 be redirected. The waste set 81 . 82 comes with the seal 103 at the bottom of the drain hole, then the flange is complete from the tub. 112, 108, 109 with the threaded M4 screws 107 put on, with the screws 107 can be threaded into the channels. By alternately tightening the screws 107 , diagonally from above, the seal 112 pressed, with which the set is fastened is done. The channels are used to exclude residual water 105 . 106 from the tub, for example with silicone, symb. 126 , injected or with appropriate stopper 126 locked. If the set is primarily to be installed on the tub from below, it is also possible to use the threaded inserts 124 so the other way around that the two M4 mounting screws 107 can be attracted from below.

That over the lowered stopper 113 with oval rejection 127 , via the connection 128 , Lip seal 129 , from the bathtub into the communicating tube 130 rejected bath water rises in the com. tube 130 , down to under the upper edge of the bathtub 17 high and there over the 90 degree redirection not shown 77 and the connection 76 in the overflow head cpl. 43 or in its overflow space 74 initiated from where it is over the overflow pipe 75 , the connection 83 , for this 75 on the waste set, upper part of the housing 81 , over the comb 90 , vertical wall 91 , gets into the odor trap water and so through the horizontal outlet 84 and the connection 85 can drain after the drain pipe on the building side. That with the relief valve open 22 from the middle zone 11 about the hydr. plug-in connection 46 after the complete next to the overflow head. 43 arranged, drain funnels 62 incoming water flows through the additional discharge 94 who have favourited RV flap 100 and the tubular chamber 92 into the odor trap water 81 . 82 and from there across the horizontal exit 84 and the connection 85 after the drain pipe on the building side.

The mixed water bottom inflow is, according to a further embodiment of the invention, designed so that the mixed water, over the entire length of the com. tube 130 distributed via shower head-like nozzles 133 in the comm. tube 130 and 127 and so over the sealed stopper 113 flows into the tub. One possible embodiment is an oval extruded profile 130 with all-round mixed water channel 131 , Mixed water connection P ₂ , sewer 131 , because of the bridges 137 , on both sides with two plugs 138 locked. The channel 131 sits on the waste set housing 81 in the channel 135 away, this is plugged 139 and the canal 131 with a symbol only connecting line shown 136 connected. Because of the introduction of the nozzles 133 become the constipations 134 to be required. In principle, the mixed water P _{2 flows} from the P ₂ drain connection 64 . 65 after connection 132 on the extruded profile 130 ,

In 6 a solution can be seen, like at the connection 132 a pipe bend 147 who is in a hydr. plug-in connection 148 connected to the P ₂ drain connection 64 . 65 trained, inserted and in another hydr. plug-in connection 149 , with also possible length compensation with the channel 135 connected.

Instead of the profile 130 could the nozzles 133 also about a, at 64, 65, respectively. 132 connected, over the entire length in the com. tube 77 . 127 inserted hard plastic hoses, nozzles 133 be incorporated into this; this tube could also be a double tube connected by means of a central rib.

For cleaning the com. tube 77 . 130 . 127 it might even be sufficient if the P ₂ mixed water was only around the top, in the overflow space 74 connection 76 , in the com. tube 130 , then without 131 would be injected; Mixed water P ₂ then similar 46, 47, 48 after com. Tube above.

According to a further embodiment of the invention, the drain set, housing 81 , Ground 82 , designed for a drain hole with a diameter of 90 millimeters; then the tape fastening compared to the three M5 screws in the version according to GM 29 82 301 results in a further improved access, larger diameter of the dip tube sealing point.

With whirlpool the com. tube 127 also hair suction protection ( DE 100 38 246 A1 ). The one with the seal 103 on the waste set 81 . 82 built-up whirlpool floor extraction nozzle 140 has the cylindrical strainer that can be removed towards the bathtub 141 ,

Because of the preferred arrangement of the baffle 146 (Analogously e.g. item 70 figure 1 _c1 DE 10038 246 A1 ) the cyl. room 143 , above the drain hole D ₂ = 52 +3 / 2, in the intake manifold 140 , such a large diameter that the outside of the cyl. scree 141 two rectangular surfaces are created, the two cross sections of which correspond to half of the drain hole cross section. From the cyl. room 141 is the oval tube 144 to the first 128 analog, connection 145 and so diverted to the whirlpool pump. The distance between the line of symmetry of the drain hole and the connection 128 must be so large that the connection 128 in terms of height under the tub floor.
