DE10107671A1 - The submerged inflow into a bath tub, with mixed hot/cold water, is controlled by a hydraulic miniaturized triple-chamber system integrated into the rotary control knob - Google Patents

Abstract

The submerged water supply into a bath tub, with a mixture of hot and cold water, has a hydraulic triple-chamber system separation unit integrated into a rotating grip knob, with two or three concentric mounting drillings or a single horizontal drilling at the upper edge of the bath at the tap or faucet fitting. The rotary axis is at right angles to the base of the bath, on the symmetrical line. The drilling to give the mixed water inflow (P1) is at the upper edge, and the mixed water outflow (P2) is taken through an outflow pipe at the back of the mixing tap assembly. The relief valve to empty the center zone is at least 20 mm above the bath edge and well over the level of dirty water.

Description

Protection against back suction of sub-level bathtub mixed water inflows a miniaturized integrated in horizontal handles on the upper rim of the tub Hydraulic three-chamber system separation device.

As is well known, sub-level bath inflows can either be done using a free flow section, Patent specification DE 196 04 760 C2 or hydraulic three-chamber system separator, Patent 44 39 050 can be secured. In 100 38 246.0-42 is a horizontal intrinsically safe Inlet and overflow set with free flow path, that is under the upper tub edge, so arranged below the dirty water level and the horizontal rotary handle for Bathtub sealing plug OPEN / CLOSE, which is accessible at the top of the tub rim, proposed. One-hole bath rim fittings, preferably to be combined with intrinsically safe inlet and overflow fittings are from OS DE 199 01 854 A1 and 100 38 391.2 known.

Both the free flow path and the system separation device of the above two patents and also 100 38 246.0-42 are under the upper tub rim and therefore under the Wastewater level installed and thus need between the back of the bathtub and their Tile facing a drain funnel, such as. B. of pipe cutters under their Relief valve known.

The discharge of this inaccessible drain funnel to the building-side sewer pipe is not without problems. A good controllability of the funnel would be a Safety overflow to a drainage shell on the outside of the tile covering of the tub; this would mean additional effort and is difficult to sell enforceable.

The invention is based on the problem, contrary to the protection of non-intrinsically safe Inlet and overflow fittings by means of a 150 millimeter above the top edge of the tub the pipe breaker A2 arranged on the building side, with a self-sufficient bathtub Realize low-level inflow, the entire piping of which can be arranged below this to be able to and still, with a minimal overhang over the upper tub edge, on one To be able to do without the drain funnel behind the bath apron.  

To solve this problem, the fact is used that both with the one-hole Bath rim thermostatic mixer with bath / shower switch and z. B. only one Twist grip, as well as the horizontal inlet and overflow set Set up horizontal twist grips over the top of the tub. According to the invention preferably a hydraulic three-chamber system separator, in (a) horizontal (n) - Integrated handle (s), so above the upper tub edge and thus above the Waste water level arranged that under the relief valve for emptying it Middle zone of the one prescribed by current standards DIN 1988 part 4 or EN 1717 There is a minimum distance of 20 millimeters from the dirty water level. at Ensure that water exiting the relief valve is always from the top to the tub is the tub, or the upper edge of which is the funnel for the System separator, as is also the case with the above tube interrupter A2 in the building-side wall, but here, contrary to the invention The tub cannot be set up freely and flush-mounted piping is required.

Advantageously, when integrating the system separating device into the three or two concentric, horizontal adjustment handles of the one-hole Bathtub edge thermostatic mixer with a non-intrinsically safe inlet and Overflow set can be combined; in the space between the back of the tub and its Tile facing is the connection for hot and cold water on the building side. at Integration of the system separator in the horizontal twist grip for Sump plug OPEN / CLOSE according to a further embodiment of the invention proposed intrinsically safe horizontal on and overflow set with overflow medium communicating tube can either use the one-turn handle Thermostatic mixer or the one-hole bath rim mixer also mentioned at the beginning then probably with a single-lever cartridge, with or without Wax expansion element can be used.  

Embodiments of the invention are shown in the drawings and are shown in described the following in more detail:

There follows the explanation of the invention with reference to the drawings according to structure and possibly also according to the mode of operation of the illustrated invention.

1a, b., C, d and e

The fitting housing is completely attached with the nut 7 to the thread on the fitting housing upper part 6 at the bottom of the hole 2 at the upper edge of the bath tub 1 , to a certain extent inaccessible, in the space between the back of the bath tub and its tile covering. The plastic injection-molded part insert 24 with its O-rings 30 and 28 is inserted completely into the fitting housing, in front of which the plastic injection-molded part insert 24 is inserted, before it is firmly connected to one another via the lower part 6 and the lower part 9 . With the horizontal walls 29 on the insert 24 , the chambers 35 , mixed water p1 after the hydraulic three-chamber system separator 38 , mixed water P2 from behind 38 to the bath, chamber 36 and P2 to the shower, chamber 37 are formed in the upper part 6 . The mixed water riser pipe 25 is introduced into the chamber 35 ; from the chambers 36 and 37 the downpipes 26 Misch P2 are discharged to the tub and 27 P2 to the shower. The tubes 25 , 26 and 27 are connected at the connections 18 with the O-rings 28 to the lower part 9 of the valve body, consisting of the upper part 10 , the lower part 11 and the lower part 12 . At the lower part 12 on the underside there are the four connections for pressure-hoses covered with metal mesh, two hot and cold water 92 and mixed water from the fitting connection 23 to the tub and analog connection to the shower, preferably a slip shower. On the upward-facing side of the lower part 12 below, the sealing image 14 with the two supply lines hot and cold 16 to and the discharge of mixed water 15 from the thermostatic wax expansion cartridge 13 . The hot and cold water 92 , 16 flowing to the cartridge returns deflected by 180 degrees from this 13 as mixed water 15 and flows via the diversion channel 17 closed with the plug 19 via the mixed water riser pipe 25 into the chamber 35 . The removable to over the upper edge of the bathtub 1 Th-K 13 is pressed with the fastening sleeve 20 and the nut 21 against the Andichtbild 14 in known manner. Into the seats 31 , 93 chambers 35 , 36 and 37 , the tub / shower switchover, lower part 74 , which is preferably ultrasonically welded with the system separator 38 , is inserted, or with the radially sealing O-rings 34 , which are offset in diameter from one another, to the chambers 35 , 37 , 36 connected. With the pushing in of the bath / shower changeover with system separating device from above, from the upper bath tub edge 1 , the central shaft 75 and the hollow shaft 76 for setting the Th-K 13 are also connected to it. The driver 77 is spotted on the shaft 75 and the driver 78 is spotted on the hollow shaft 76 . The driver 78 connected to the outer adjusting rotary handle 3 and the driver 77 connected to the inner rotary handle 4 , in whose central free spaces 94 the system separating device 38 is located, are in the free space 71 between the underside of the bottom 63 of the central zone 54 , 38 and the top of the cover 67, respectively up to the pipes mixing 68 P1 and mixing 69 P2 of 69 the system separator 38 freely pivotable. The hollow shaft 76 is guided through the through-hole 72 and the through-pipe 73 through the tub / shower diverter 74 so that no dripping water can get into the room 89 of the Th-K 13 from above, but any pressurized leakage water from a defective seal 14 can cause this would be visible above the edge of the tub. The same applies to the passage of the axis 75 through the hollow shaft. The axes 76 , 75 with their drivers 77 . 78 70 System separator 38, tub / shower switch 74 are threaded on the Ultraschalverschweißen.

The hydraulic three-chamber system separator 38 , which u. U. Perhaps even further flattening of the standards already mentioned above could be a system separation DA / HD, is with the cover 67 , which is in one piece with the lower part 66 , bottom 63 , the central zone 54 and the section mixed water supply pipe 68 at the ultrasonic welding point 70 connected to the lower part 74 , or the tub / shower conversion, switching chamber 80 . With the weld seam 70 , the tube 68 and tube 79 are also connected to one another. The mixed water discharge pipe 69 , P2 from the system separator opens directly into the switching chamber 80 ; are led out of this 80 , alternatively in the case of the sealing seats 83 with the sealing cones 84 after the tub and 85 after the shower, the two oval pipes 81 and 82 can be closed . Pipe 81 mixed water P2 from switching chamber 80 to chamber 36 tub, O-rings 34 in seats 31 and pipe 37 P2 from 80 to chamber 37 , after shower, pipe 27 . The outlet 61 and thus also the seal of the upstream check valve 58 opens into the middle zone at the bottom 63 , so the water P1 also enters the pipe from the middle zone 54 at the bottom 63 via the seal 62 and the downstream check valve or its sealing cone 60 69 after the switching chamber 80 . The system separator 38 shown thus has no internal level difference. Since the device is a special version only for the fitting according to the invention, this should probably be possible in terms of approval; otherwise the RV on the pre-pressure side, with its seal 61 and its sealing cone 60, would have to protrude high into the central zone 54 . The transition 90 form according P1 through the diaphragm 39 into the space 55 below the diaphragm chamber lid 64 is only symbolically, as well as the connection cover 64, membrane 39 -Einspannung to base 66, or Membraneinspannbund 65 is not shown. Also not shown is how system separator 38 and switch 74 are secured against pushing up or pushing the O-rings 34 out of their sealing seats 31 .

Below is the water flow Fig. 1a

Cold and warm water flows from the building-side connections, preferably on the bathroom floor via metal-fabric-coated shower hoses via the connections 92 , 16 to the Th-K 13 , 14 and, deflected by 180 degrees, returns as mixed water at 15 and arrives via the Channel 17 and pipe 25 into chamber 35 . Between the seats 93 and 31 , the mixed water P1 comes into the analog chamber 35 between the horizontal walls 95 , and flows via the pipe 79 and the pipe 68 in front of the RV 58 on the pre-pressure side, behind which 61 the water P1 flows, by means of the differential pressure P1 / P1 with the diaphragm 39 , against the force of the spring 91 closed relief valve, for the operation of the three-chamber device u. U. please claim 1 patent 44 39 050. From behind the rear pressure RV 59 , the water P2 flows via the pipe 69 directly into the switching chamber 80 . In Fig. 1b a self-switching changeover is shown, which would not be necessary since the shower is also secured by the system separating device. The changeover here consists of the rocker 86 with the two sealing cones 84 , 85 . When the outlet 85 , 83 is closed , the mixed water P2 flows from the changeover chamber 80 via the oval pipe 81 to the chamber 36 and becomes from it via the pipe 26 after the connection for the metal-fabric-coated pressure hose 23 and thus to the bath tub or the non-intrinsically safe inlet and headed overflow set.

FIG. 2a, b, c, and d

The integration of the hydraulic three-chamber system separator 38 in the horizontal rotary handle for bathtub plugs OPEN / CLOSED 120 is the alternative solution for securing by means of a free flow path as suggested in 100 38 246.0-42. The higher bath water levels that can be achieved with horizontal inlet and overflow fittings are also very desirable for whirlpools. The discharge 37 , 47 in 100 38 246.0-42, the communicating tube 122 to the overflow space 127 and thus for re-discharge via the conventional overflow pipe 121 , as well as the sub-level mixed water supply, 8 , 8 ', 8 ", 46 in 100 38 246.0- 42, from the Fig. 1a, b, 2 and 3. registration projecting well be seen and described in detail there. the gear 120 to the bowden control for plug oN / oFF, there is to be seen. 1e in Figure and described there.

In the preceding FIGS. 1a and b of this application, the system separating device 38 is rigid within the rotary handles 3 and 4 within the center in the front. Handles formed free space 94 not rotatable, in one piece with the tub / shower diverter 74 which can be pulled out upwards. In the below-described Fig. 2a-d of the intrinsically safe Horizontalen- (input) and overflow is the same Systemtrenngerätchen, again exactly 57 'the relief valve 40' for emptying the central zone 54 ', the upper with its channel outlet with the prescribed minimum distance 88 above the Bathtub edge 1 arranged. The membrane chamber cover 64 of FIGS. 1a and b, however, is here the horizontal rotary handle 100 for actuating the gear 100 '. The handle 120 or the membrane comb cover 64 'is screwed to the lower part 66 ' of the central zone 54 'by means of the screw-on support points 24 and the six Ejot screws 126 screwed into the domes 125 , when the membrane 56 ', clamping collar 56 "is clamped; in FIGS. 1a and b diagrammatically not shown. the mixing water, P1, 96 inlet and Abfuhr-, P2, 122 -pipes, analogue 68 and 69 are at the hydraulic-plug connectors 101, 102 or NHA O- rings 103 to the lower part 112 is connected to the P1 supply line 110 and P2 line 111 as follows, with the rotation of the handle 100 via the tubes 96 and 97 , and via the rotatable part consisting of hydraulic plug connections 101 , 102 , lines 108 , 109 is transferred from the chambers 106, 107, the horizontal walls 105 with the O-rings 104 and the drive pin 119 to the gear 120 for actuating the Bodwdenzuges 129 for bath plugs oN / oFF. the O-rings 104 are in the Sit 115 of the lower part 112 rotatable. The safeguards against the rotating part 104 , 105 and the system separating device 38 , 101 , 102 rising out of the way are not shown in the drawing. The set top 116 and bottom 112 are z. B. heat mirror welded together. The overflow pipe 121 , or at least its upper section, is integral with the lower part 112 , while the height of the communicating tube 112 in the collar 123 can be displaced in a sealed manner in the overflow space 127 because of different trough overflow levels. The bath tub water, which is discharged in a known manner via a lowered sealing plug or in a whirlpool side suction, flows via the communicating tube 122 into the overflow space 127 and flows out via the overflow pipe 121 to the siphon of the set. The mixed water, preferably coming from a single-hole bath rim thermostat fitting, is connected to the fitting via a metal-fabric-coated pressure hose at connection 110 and flows in the lower part 112 in the rectangular channel 113 to the chamber 106 and is discharged from it via the drain 108 to Plug connection 101 and so via the pipe 96 in front of the back pressure preventer 58 "on the pressure side. Behind the RV 59 on the back pressure side, the water P2 flows via the discharge pipe 97 , the plug connection 102 , the discharge line 109 to the chamber 107 and from there via the rectangular pipe 114 , in Lower part 112 , after connection 111 .

The set is fastened with the screw 118 and the seal 117 at the bottom of the hole ϕ52, 2 , on the edge of the bathtub 1 . The tubes 96 and 97 are guided through the screw 118 , or the central bore thereof , and after this has been removed, good access from above to the overflow space 127 and the tubes 121 , 122 is possible, as can be seen from FIG. 2c, while the gear 120 not accessible in a known manner. Water draining from the relief valve 57 ', 40 from the central zone 54 ' can advantageously flow freely downward into the overflow space 127 , compared with the preceding FIGS. 1a and b, while the nut 7 must ensure in the thermostatic fitting in the event that this occurs the tub rim does not ensure that water always flows from the relief valve 40 , 88 towards the tub and cannot come out to the bathroom floor.

Fig. 3

When using a one-hole fitting with switchover to shower using the ceramic disks, fitting as described in OS DE 199 01 854 A1, the slip shower, contrary to the fitting of the preceding FIGS . 1a-e, would have to be secured with two non-return valves. Instead of a mixed water inflow in the area of the bottom of the tub, the mixed water P2 from the fitting 111 of the preceding FIGS. 2a-d could also lead to a mini inlet shell with its inlet 131 , its tight cover 133 of the standard overflow hole D1 and a mini Cover 132 , be guided.

Fig. 4

With the set of the previous Fig. 2a, b, c and d, the slip shower can also be secured if z. B. the one-hole fitting of FIG. 2, as described in 100 38 391.2, is equipped with two additional connections 133 and 134 . Hot and cold water is still drained to and from the tap and mixed water to the tub and shower. The water coming from the mixer cartridge is, however, via the tub / shower changeover from connection 130 to connection 120 P1 and only from connection 111 P2 via connection 134 back into the changeover chamber ( 42 first note) of fitting 135 initiated. There is therefore no direct introduction to item 41 above. Note .; here the system separator 38 ', connections 110 and 111 , or 133 and 134 are hung between them.

The system separating device 38 ', 100 withdrawn from the hydraulic plug-in connections 101 , 102 , as can be seen in FIG. 2b, can also be attached to a lower part with rigid plug-in connections for P1 and P2, also fastened to the bore 2 by means of a hollow screw 118 and seal 117 , Tubes 96 and 97 used to secure the disinfection of air systems whirlpools, u. U. sb Fig. 3 OS DE 44 39 060 A1 can be used. Except for the tight passage of the tubes 96 and 97, the screw 118 with the seal 117 and the lower part with the fresh water supply P1 and drain P2 then closes the bore 2 after disinfection. Water from the relief valve 40 flows as in FIGS . 1a and b via the tub rim 1 into the tub.

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