Abstract

The thermostat fitting integrated in the outflow head (16), consists of two removable subassemblies, a thermostat control member to one side of the overflow hole and a subassembly (80) with three hydraulic plug and socket connections. This subassembly contains ceramic washers (84), an insert (85, 86) for mixed water (60), an on/off and flow rate adjustment, and a bath/shower changeover switch, all in a common housing.

Description

Combined bath inlet, overflow and drain thermostatic fitting on or behind the Overflow hole D1 with a mixed water supply to the bathtub below the upper edge and with protection against back suction of bath water below the level of upper bathtub edge offset laterally by means of an overflow hole D1 arranged free flow path as described in DE 196 04 760 C2 and EP 07 41 259 A2.

A single-lever mixer inlet, overflow and outlet fitting in front of the overflow hole is known, secured by a hydraulic three-chamber system separator (BA) in Cartridge design (P44 39 050.5-42). Also known is a single-lever mixer, and drain fitting with mixer arranged behind the overflow hole D1 in the drain head Cartridge (198 11 586.5, 197 53 808.8, 197 41 344.7 and 197 12 396.1).

In DE 196 04 760 C2 there is a mixed water supply in the area of the bottom of the bathtub and in EP 07 41 259 A2 a floor inflow in connection with a tub overflow communicating tube as described by Geberit Clou for wash basins. In These registrations are also the relevant registrations for soil inflows and for the Tub overflow indicated by communicating tube.

Especially with a drain head or valve body made of plastic, the flange O-ring seals of a single-lever mixer cartridge are not without problems and so are the Water guide channels for supplying and discharging the hot, cold and mixed water The above cartridge seal is difficult to manufacture.

In order to have fewer problems here, the thermostatic fitting according to the invention consists of two Assemblies that can be removed via the overflow hole D1: thermostatic control element and second assembly, which uses the ceramic disc for mixed water OPEN / CLOSE, as well Flow setting and the tub / shower switch includes formed. With a thermostatic fitting on or behind the overflow hole D1, the hydraulically in front of the thermostatic control element in the cold and hot water Pipes to this required backflow preventer via the overflow hole D1 Bathtub to be interchangeable. It is desirable that the depth of the valve  Basic body, or the drain head slightly below the 55 approved according to the standard Millimeters. From the rear, the base body of the fitting should be complete, or the individual parts of which are not opened by any sliders in the injection molds.

The invention is based on the problem of all the necessary water channels, suitable for plastics, only by means of connections with radially sealing O-rings can.

This is possible because the drain head is complete. from the parts drain head (valve body) and that, behind the overflow hole D1, the encapsulation space for the free flow path opposite, again parallel to the back of the bathtub wall, laterally offset arranged receiving or connecting part for the thermostatic control element is formed and on the other hand the assembly ceramic top part and tub / shower Switching in one and the same housing, here the drain head, by means of hydraulic Plug connections on the bottom of the drain head to the thermostatic control element coming mixed water and to the forwarding (in or at the drain head) to the tub and is connected to the shower hose. Cold and warm water is e.g. B. means metal-fabric-coated pressure hoses connected to the drain head and flows over the in Drain head arranged backflow preventer inserts to the hydraulic connections in the drain head cpl. and so to the actual connector for the Th. StE. The mixed water comes back from the control element to the drain head, or to those on its bottom plug connection for the unit ceramic top part and tub / shower Switching. The connections cold, warm and mixed water, in the drain head cpl., between the individual parts of the drain head and the connecting part for the Th StE are done radially sealing O-rings and are located in the space outside of the overflow space Back of the bathtub and its tile covering.

Space is also won because the so-called gear for tub plugs OPEN / CLOSE to the side, moved behind the Th StE, arranged transversely.

In order to be able to arrive at a short and easy-to-remove Th SE, version 2 , with a temperature preselection setting deflected by 90 degrees, a cam disk is used according to the invention instead of the standard setting spindle. The overpressure (protective) spring is removed from the standard Th StE, in part 2 , and inserted into the mechanical connection: cam disc, which can be moved out of the Th StE and moved out of the Th StE. If the pressure spring with its lever is in the overflow space of the drain head in the overflow or bath water, this is harmless, since the adjusting forces given by the pressure spring in the Th StE are relatively large and the sensor itself or the mixing cone is only to do so indirectly to have.

The attachment from the drain head complete, with hood for the encapsulation space for the pipe interrupter A1 with 30 or 20 angular degrees of deflection, to the bathtub, bayonet-type, such that, with the drain head completely mounted, the full cross section of the overflow hole D ₁ = 52 _-2 ⁺³ is available. Via the overflow hole D1 the following can be removed towards the bathtub:

After pulling out the fastening and locking plate, in the direction of the line of symmetry from D1, first the discharge tube with its wall, which has the U-shaped free cut in The fastening plate then closes after loosening a screw (not shown) up and pull the assembly out of its hydraulic plug-in connections Ceramic disc top and tub / shower switchover. Then after the Removal of the transmission lever, cam disc after setting pin on Th StE and Removal of the covers the backflow prevention inserts are removed. After the loosening and removal of a fastening ring, not shown, with possible controllable hydraulic encapsulation, the Th StE from its connector, in parallel to the bathtub wall, pulled out and also over the overflow hole to the bathtub be removed. Finally, it could also U. if this is required as maintenance was considered possible, the A1 in a special version via the access breakthrough out of the encapsulation space, and over the overflow space and again over the overflow hole also pull out into the bathtub; here z. B. the hose that the Mixed water to the nozzle leads into the encapsulation room, from the space between the bath tub Pulled in the back and its tile facing.

The division of the function of a hot and cold water mixer cartridge into Thermostatic control element and ceramic disc insert for mixed water OPEN / CLOSE and Flow rate adjustment brings besides the favorable constructive installation possibility  also the great advantage that the separate pure rotary movements for temperature preselection and mixed water flow on an extremely low cover in front of the Overflow hole are cheaper than the sweeping pivoting movements of a single lever.

According to a further embodiment of the invention, the thermostatic fitting according to the invention is a modular system, with convertible injection molds for parts 1 , 2 and u. U. 3 , built. It can be offered:

normal, intrinsically safe inlet, overflow and outlet set with mixed water supply to the tub at the overflow hole D1,
Thermostatic fitting as described above,
u. U. Thermostatic mixer with floor inflow and conventional overflow and especially as an alternative to the previous. Thermostatic tap:
Thermostatic mixer with floor inflow and bath overflow at drain hole D2, using a communicating tube such as Geberit Clou for wash basins.

The mixed water supply to the nozzle of the A1 with, for. B. 20 degrees of deflection must not have a strong deflection shortly in front of the nozzle, since otherwise the exit jet would scatter, which would result in too much splash water in the 20 degree deflection or in the re-entry bore. The above must also be ensured for the supply hose of the thermostatic fitting with a conventional mixed water supply to the bath. In the case of a valve with a floor inflow, the mounting or connection part for the Th StE is recommended. In part 2 of the connection part here is an additional mixed water connection to which the mixed water z. B. by means of a metal-fabric-coated pressure hose from the appropriate, from vorst. known connection is performed on the drain head.

The forwarding hole from vorst. Mixed water connection opens at 90 degrees redirected into a second additional, larger horizontal hole at the top, which the Mixed water brings to the nozzle part with its 20 degree bend.

In the case of an inflow of soil, the special version of the A1 is installed in reverse in the encapsulation space and sealed by a seal in the front. Bore slidable tube is then formed according to the invention on the one hand a releasable coupling to A1 and on the other hand the coupling tube can be inserted into the bore so far that the assembly ceramic top part and tub / shower switchover, in spite of the here, in version 2 , actually overlying arranged horizontal flow and calming section, again as in the conventional vorst. Thermostatic fitting can be pulled out of the three hydraulic plug connections. The discharge of the mixed water to the bathtub floor takes place from a connection in the hood of the encapsulation room of the A1, as in vorst. referenced applications described, the u to an inlet, overflow and drain at the drain hole D2 of the tub again here from the FIG. 6a. b can be seen. When the A1 is used upside down in the encapsulation room because of the inflow of floor space, there is space here for the introduction and diversion of the communicating tube, which is designed as an additional space in the encapsulation room, into the actual overflow space of the drain head. After pulling out the fastening and closing plate part 2 in a known manner, the separate deflecting part can be removed towards the bathtub for the discharge and introduction of the communicating tube. If the first step is to remove the ceramic disc upper part and the bath / shower switchover. Coupling tube is inserted into the connection block anyway, could also be pulled out in the same direction by pulling the AI out of its connection in the hood of the encapsulation chamber and theoretically also threaded out of it to the bathtub. This would be easier than before. with the conventional fitting also having to pull the hose in.

The bottom inflow is preferably for hygienic reasons, in particular because unsightly pollution when cleaning the bathtub, such as a backflow preventer have represented. If then also in the discharge pipe from the encapsulation space Prevention of backflow is also possible here if the siphon is clogged and overflowing Bathtub no more water can be stowed in the bathtub.

As in the hood of the encapsulation room as before. known applications known; Always, not shown here, are slots that ensure under all circumstances that a Any dirty water level in the encapsulation room is always 20 millimeters below the nozzle remains, could theoretically in the absence of an additional safety overflow if the two failed Backflow prevention bath water unnoticed in the space between Escape the back of the bathtub and its tile covering and cause water damage. The RV at the bottom inflow is ideally flushed UP with every mixed water. Around a possible sticking of the float for the RV to the encapsulation space  overflowing bathtub and clogged siphon will be practically impossible Proposed according to the invention purely mechanically with each bathtub plug OPEN / CLOSE this manual movement every time the RV swimmer in the expanded space of the Slightly raise the discharge pipe, as is already the case for actuating the relief valve a BA on an inlet and overflow set is proposed.

If the cross-section of the discharge pipe of the discharge funnel for the A1 or Encapsulation space as large as the cross section of the overflow pipe is selected, the Soil inflow, e.g. B. be fully held over by playing children and then everything at A1 escaping mixed water could be easily removed.

There follows the explanation of the invention with reference to the drawings according to structure and Operation of the illustrated invention:

Fig. 1 (a, b, c, 2a-g and 3, via the flexible head, connected to the drain head ( 16 ), metal fabric-coated connecting hoses 119 flows on the one hand hot water from the connection 50 to the check valve 57 and from this via the discharge line 52 , 59 to the hot water -Connection 38 on the receiving or connecting part 31 and so via the chamber 35 to the hot water inlet at Th.StE 32nd

Analogous to vorst. The cold water coming from the hose 119 flows via the connection 51 and the RV to the discharge line 53 , 59 and from there via the cold water connection 38 into the chamber 36 and thus to the Th StE 32. The mixed water emerging from the Th StE becomes via the chamber 37 and via the connection 40 from the connection part 31 back to the mixed water inlet 58 , 59 or to the drain head 16 . The mixed water is introduced via the hydraulic plug-in connection 60 into the connecting pipe 82 , 97 of the ceramic disc insert assembly and bath / shower switchover 80 . The mixed water reaches the ceramic disk insert 84 through the inner diameter of the pressure seal 100 ; behind this, it emerges, deflected by 90 degrees on all sides, out of the basket with sieve 85 and flows again deflected by 90 degrees, now in the opposite direction, via the overflow space 91 to the tub 95 / shower 88 switch 104 , 105 , 106 . In the normal spring position tub, the mixed water flows through the tube 94 and the plug connection 61 , 97 , 98 back to the drain head 16 and is from this at connection 64 , or via the z. B. metal fabric sheathed hose 65 to the nozzle 1 of the A1 in a special version (in Fig. 1b only symbolically shown with 30 degrees of deflection, sb better A1 of the following Fig. 7) and so in a known manner from the outlet of the suction tube 9 via the Discharge tube 10 passed into the bathtub 21 .

How the discharge tube 10 is held with its wall 76 on the A1 and in the drain head 16 by means of the fastening and closing plate 25 is described in more detail in 196 11 586.5 single-lever mixer fitting on or behind the overflow hole of a bathtub. When the 105 tub / shower 104 switch is pulled, the water flows through the pipe 83 , 97 , 98 to the plug connection 62 and in the drain head 16 to the shower hose connection 63. The spring against the force of the tub / shower switch is the pin 105 for switching pulled out after shower 88 is not shown.

The mixed water flow rate and mixed water OPEN / CLOSE are set via the handle 87 via the Ms spindle 86 , 101 , 102 and the sieve basket 85 on the ceramic disks 84 . The cam disk 100 is set by means of the temperature preselection disk 111 via a sleeve (not shown) which is threaded onto the housing neck 102 and supported thereon via a coupling (or a part) which is again not shown.

Fig. 2d, the Pimpel 92 transmits the respective height of the Archimedean spiral of the cam plate 110 to the lever 107. Normally, the leaf spring 108 rests with a corresponding preload on the corresponding stop at 107 and thus transmits the respective lever position directly via the Pimpel 109 the adjustment plunger 112 of the thermostatic control element 32. The leaf spring 108 fulfills the function of the pressure spring, as can be seen in FIG. 2g. The leaf spring 108 is, for. B. dotted at the top of the free cut on the lever 107 . If necessary, the overpressure (protection) spring pre-tension already specified by the design of 107 , 108 could be adjusted more precisely by bending adjustment. The lever 107 is e.g. B., easily removable, stored on the covers 56 of the RV's 57 .

The functions of the lever 107 and the leaf spring 108 can also be combined in a Bihler automatic spring steel wire bent part.

Fig. 2e and f, which extends parallel to the tub wall, sealed by an O-ring in the bore 46 after the transmission case 43, square shaft 47 for actuation of the transmission, or in this case lever 44 for actuation of the well plug 133, via the Bowden cable 118 can, as can be seen from FIG. 2e, preferably be carried out via the lever 41 in the conventional thermostatic fitting.

In the case of a fitting with a floor inflow and an overflow by means of communicating pipes, the cover hood 117 'on the tub side is built on the one hand to be extremely low and on the other hand is sealed all around the bath tub. It is then more economical to carry out a rotary movement sealed by the hood 117 '. The embodiment of FIG. 2f with a shift drum 34 , 34 ', which actuates the axis 47 , 47 ' via the pin 42 , 42 ', or here the lever 44 , 44 ', will then be more favorable. In the thermostatic fitting with floor inflow described below under further development of the invention, the lever 44 'movement and z. B. an additional Bowden cable 145 always the float RV 142 in the drain of the encapsulation space 28 'with each briefly raised and then immediately lowered again.

Fig. 5a, b and c (further embodiment of the invention)

Construction kit here thermostatic mixer with mixed water supply in the area of the floor Bathtub and tub overflow using communicating tube.

The water flow in the discharge head assembly ( FIG. 2a) with the inserted Th SE 32 'and inserted assembly 80 ' ( FIG. 3) is analogous to the differences listed below as described above under FIG. 1.

In contrast to the conventional thermostatic fitting, the mixed water flows from the connection 64 'via the metal-fabric-coated pressure hose 65 ' to the connection 67 at part 2 of the receiving or connecting part 31 '. From the connection 67 , the water flows through the bore 119 into the horizontal bore 120. In the bore 120 , the coupling tube 121 is sealed 123 displaceable. The tube 120 is preferably designed so that water without swirl and swirling reaches the 20 degree arc of the nozzle piece 125 with a correspondingly comical design 122 . In the position drawn out of the connecting part 31 'or out of the bore 120 , the tube 121 is hydraulically coupled to the nozzle piece 125 , 124 . The mixed water flows in a known manner over the A1 ( Fig. 7). The suction tube 9 'outlet is hydraulically coupled with the O-ring 73 ' on the rear wall of the hood 71 'to the so-called discharge tube 10 ' . Fig. 6a, b. The discharge pipe 147 to the bottom inflow ( 148 ) is connected to the discharge pipe 10 '.

The height of the bathtub water level is also communicating in the tube 127 , 134. Overflow water passes via the transfer area 135 to the rectangular outlet 136 and from there via the deflection part 138 at its rectangular circular ring segment outlet into the overflow space 19 'of the drain head 16 '. Despite the plug connections 60 ', 61 ', 62 'and the RV's 57 ', 56 ', the cross section of the overflow pipe 18 ' and thus the corresponding derivation is provided on the bottom 68 'of the drain head 16 '.

The discharge pipe 15 'from the encapsulation chamber 28 ' is only introduced at the very bottom at the inlet 129 into the elbow of the overflow pipe 18 'in order for the height from the bath tub floor to the overflow hole 20 ' for both pipes 15 'and 18 ' to serve as a lifting line (such as a corresponding storage height) to have received optimal drainage performance.

The mini control funnel with its discharge tube is not shown in the bathtub for the control option "dripping tap" as in previous. patent can be seen. The control rejection tube could be mechanically closed with each stopper 133 , 44 ', 118 '. B. be closed by a pen, which could also have a cleaning effect. The control reject tube and the mini funnel are preferably part with the deflecting part 138 .

In Fig. 5c, the three actuators, the axes of which each are performed by itself, sealed by the cover 117 'can be seen. To operate are: mixed water temperature preselection 111 ', mixed water flow rate and OPEN / CLOSE 87 ', bath plug 133 OPEN / CLOSE 146 and only symbolically shown bath / shower switch 105 ', this pin is also not drip-proof, but led out tightly from the hood 117 '. On the axis of the pointer lever 111 'for temperature preselection is, for. B. a gear segment that rotates a connected to the cam plate 110 'second tooth edge. Because of the angle 15 degrees of the neck 102 bevel gear! The hood 117 'is also z. B. by means of an all-round O-ring tight, but not drip-proof, at the edge of the bath tub around the overflow hole 20 '. The overflow spaces 135 , 138 , 139 , 140 , 19 'behind the hood 117 ' and the bath water are depressurized with respect to one another. FIGS. 6a and b are included for completeness and described 07 41 259 A2 in detail in EP.

Fig. 7

The function of the pipe interrupter A1 in a special design is described in detail in patent DE 196 04 760 C2. It has been shown that for a safe series production, an angle of 20 degrees is preferable to the angle of 30 degrees chosen in the original tests. The so-called deflection or discharge cooler 157 is very important, in this area the suction tube 9 '''does not have the usual 3 degrees.

In the conventional thermostatic fitting according to the invention shown in FIG. 8, the encapsulation space 28 has no additional safety overflow in addition to its discharge pipe 15 , or sb . Fig. 5a 15 ', 141 , 142 , 143 , 144 , 145 . For the known two drainage options of a safety overflow, on the one hand to a drain shell on the tile covering of the bathtub and on the other hand to a separate siphon only for the safety overflow, the suggestion shown in FIG. 8 would be like this also in FIGS . 5a, b and 6a, b, to the possibility of simply introducing the discharge pipe 15 into a second siphon, a fourth possible embodiment.

In the embodiment according to FIG. 8, a RV is shown and described in the drain pipe 15 as in FIG. 5. In the mixed water supply to the tub but is 1 in the conventional valve of FIG. Opposite to the fitting of Figs. 5 and 6 no backflow. The RV shown in FIG. 8, on the bathtub side in front of the discharge tube 10, is normally always open, everything can dry out when the bathtub is not in use. Only when the tub 21 overflows over its upper tub rim does the float 149 pull the RV tab 151 in front of the outlet or then the inlet opening of the discharge tube 10 via the connection 150 .

In the hood 153 is the space 152 in which the float 149 can move up and down in a guided manner. The float 149 , 150 , 151 is easily accessible and will always be moved slightly with every full bath, which largely excludes the risk of sticking to an overflowing bathtub, with full mixed water inflow and a blocked siphon. But here, too, a mechanical forced lifting would theoretically be conceivable for each tub plug 133 , 118 OPEN / CLOSE.
