DE10038391A1 - One hole bath edge corner fitting with sunken hot and cold water mixing and flow amount setting in symmetry line of bore in top edge of bath vertical to base in space between its rear side - Google Patents

Abstract

The fitting is designed pref. for the combination with an intake and overflow fitting inherently protected against back feeding. The opening and the closing of the hot and cold water are separated from each other, as well as the adjusting of the flow amount (24,14,15), with non-thermostat execution, also the mixing of hot and cold water results using ceramic washers. The mixing of the hot and cold water is regulated by a wax expansion material element (51), and the hot and cold water supplies (19,18), and the blending of hot and cold water in the building side piping with shut-off mixing water (24) is prevented. Also with the thermostat in use, no backflow preventer is required anymore.

Description

One-hole bath tub corner fitting with tub / shower conversion, preferably for Combination with an intrinsically safe inlet and overflow set against back suction.

It is known a thermostatic bath mixer standing under the corner of a Arrange the bathtub in the space between the back and the tile cover, EP 89 11 66 43.1. A wax expansion element under the top Bath tub edge, built-in thermostat fitting behind the overflow hole is in DE 198 40 913 A1-42 described.

Thermostatic mixer cartridges with wax expansion and ceramic disc technology, which therefore do not require a backflow preventer in the hot and cold water supply lines and can be exchanged for normal single-lever cartridges, are available as Tennostatico GT, ϕ40, Nuova Galatron, cartridge Unitherm ϕ45, Ideal Standard and thermostatic Cartridge KT 46 , ϕ45 / 46, Kerox, or Kludi Evita known; the latter being a single lever thermostat cartridge.

Protect against sucking back. EP, and their bimetallic plate are thermostats technically obsolete and the also above fitting with wax expansion element still needs a backflow preventer in hot and cold water, because hot and cold water not yet separately with the ceramic discs, as is now the case with the three the thermostatic cartridges listed on the market. These three thermostatic cartridges are currently only in, preferably as conversion kits conventional bathtub fittings to be arranged on or in the building Wall on which the tub stands is offered. Theoretically, Single lever thermostat Cartridge can be installed in the fitting DE 196 49 937 A1; this fitting with their miniaturized hydraulic three-chamber system separator for their lower level Mixed water inflow would be retrofitted according to or as in DE 44 39 050 A1, DE 199 50 302 A1 described, also approved. All known deck-mount fittings are Multi-hole fittings and, if they do not have a special so-called. Bath rim system used, not to be installed on every bath tub.  

The invention is based on the problem of a self-sufficient bathtub under the entire Piping arranged and so can also be set up free-standing and here on a free outlet for the mixed water supply by means of a known To be able to do without gooseneck enema. For pleasant bathing for two and around It is also possible to get better overflow ratios, in addition to the combination with one intrinsically safe inlet and overflow set on the overflow hole, the use of a horizontal, intrinsically safe inlet and overflow set particularly cheap. To hedge against Suck back here, a free flow path or a miniaturized three-chamber System separator, both fuses arranged below the level of the upper one Bathtub edge, on the trimmings, use.

All bathtubs can be drilled ϕ52 in the corners of the upper edge of the bathtub be ordered. At z. B. Use of a mixer tap with shower conversion and Low-level inflow in front of the overflow hole is preferably a slip shower in a tub corner can be used. If a hole is required it can also be easily second order.

To provide an alternative to the relatively complex design of an intrinsically safe mixer Having a fitting on or behind an overflow hole will solve this problem by the arrangement a standard mixer cartridge, preferably a thermostatic cartridge, in the line of symmetry this lying bath / shower conversion under a hole Bohrung52 in a bath corner, in combination with an intrinsically safe inlet and overflow set on the overflow hole, or under, as a horizontal set, another ϕ52 hole in another tub corner, solved. The tub / shower changeover is advantageously under the mixer cartridge, in their line of symmetry, like this, after subtracting the, on the upper edge of the bathtub three concentric adjustment handles, also pullable upwards, be arranged. Only when the tub / shower changeover, with two on top of it and opposite flange O-ring sealing images below, under the mixer cartridge arranged, is in the middle and under the adjustment knob for tub after shower more suitable Free space for the swivel-rotary movement of a single lever for a normal single lever or preferably a single-lever thermostat cartridge. The hydraulic connection diagrams for Hot and cold after and mixed water from the cartridge are each for simple or  Thermostat cartridge the same. It is always a question of flange O-ring seals be pressed axially. This seal is according to the invention, not as usual on Fitting housing, but on the top of the tub / shower diverter, the same Outside diameter as the respective cartridge has. The flange O-ring connection diagram Cartridge underside after bath / shower conversion top lies on the underside of the Changeover compared to the connection of the changeover and the cartridge above the actual fitting housing with the then down, each to the line of symmetry Valve ring-shaped parallel to eccentric shifted, inlet and outlet connections for pressure-coated metal hoses for hot and cold water, through which Tub / shower conversion only passed through, after the cartridge and mixed water from below derived from the changeover to bath or shower. The one coming from the cartridge Mixed water flows from this directly into the switchover or in the switchover chamber. It hot and cold water flows vertically from bottom to top into the mixer cartridge and flows, redirected by 180 degrees, as mixed water, again vertically, back, directly into the switchover from which the mixed water either to the outlet to the tub or to the Outlet after shower is passed down on the valve body. The lower flange-O- Ring sealing on the tub / shower changeover, hot and cold passages and Discharge mixes after tub or after shower is with the opposite Flange O-ring seal, connection diagram at the bottom of the mixer cartridge according to the principle actio = reactio pressed in the symmetry line of the fitting.

In the changeover, the line of symmetry lies in the changeover sealing plate tub after shower is moved at right angles to the line of symmetry of the valve. The valve body Cylinder, at the bottom of which the sealing point for the changeover is, is through the bore ϕ52 screwed through in the upper tub edge. With the valve attached Housing, the protruding cylinder with housing lower part, are the cartridge and then the change after loosening a pressure and fastening nut, the Protrude thread on the inside diameter. Cylinder, after over the top edge of the bathtub, e.g. B. for their exchange, removable. Not accessible as this B. of the Bowden cables of the operation for bathtub plugs OPEN / CLOSE is known in the Space between the back of the bathtub and its tile covering, outside around the Outside diameter of the vorst. Cylinder or the valve body arranged the Transfer from the adjusting rotary handle at the top of the bathtub edge to the pen with the  Conversion sealing plate of the tub / shower conversion arranged under the mixer cartridge. After removing the three concentric adjustment knobs, the large pressure nut must be in front can still be solved a driving spring steel wire bracket, the rotational movement of the Transfer knob to the outside of the housing, removed. The diversion of the two Driving pins on the spring standing wire bracket after the outer rotating ring is, by means of two NHA rings on the outside of the housing cylinder, tight; is also the additional Actuating pin slightly after the pin of the changeover plate and slide tightly out of it Inside the housing after the external actuation. This is necessary in order to mixer cartridge recessed under the upper tub rim with an underlying one Conversion to make any leaks visible at the top of the tub edge.

The transfer of the rotary knob movement to the, under the upper edge of the bathtub The rotating ring around the outside of the housing cylinder is detachable via the still removable spring steel wire bracket with its two driving pins, while the Transmission of the rotational movement from the above outer ring down to the firmly assembled corresponding top and bottom sections over three, by 120 degrees offset to each other, again arranged around the valve body cylinder Rods done. The backdrops or the backdrop disc fully actuate the right-angled one Pin on the separate actuating pin introduced into the housing after the Changeover. The right-angled pin is against rotation from its vertical position the lower backdrop and under the upper backdrop disc segment, both as one part, in one elongated hole each on a separate part, which, centered on the sealed, slightly back and forth forth displaceable introduction of the actuating pin into the interior of the housing after Diverter pin on the diverter, on the collar of the bearing of the link plate completely., also firmly attached to the outside of the housing. The tub / shower is preferably Changeover in a known manner, so that there are no two in the slip shower To have backflow preventer. The adjusting rotary knob for switching the tub after shower and its outside on the valve body, inaccessible actuation of the additional actuating pin after the change in the interior of the housing therefore have a separate, second, not shown return spring, d. H. if at the gag after Shower turned, this will always automatically return to the starting position tub, regardless of whether the actual changeover, the pin with the changeover sealing plate, retained by the pressure of the mixed water after shower or not.  

The advantages achieved by the invention are in particular that, in the plumb line The bottom of the bathtub, in the space between the back and the tile covering, preferably in the bath corner, optimal space for a relatively slim but high-fitting fitting is and so a fitting with a relatively high thermostatic cartridge and below in one and same tub / shower conversion lying on the same line of symmetry, minimal at the top constructive three concentric adjustment knobs, under the upper edge of the bathtub can be sunk. By arranging the tub / shower conversion under the Cartridge, the fully recessed fitting according to the invention is also particularly suitable for one Wax expansion thermostat cartridge with single lever. As a kit, the valve can then also available in a shortened version only with a conventional single-lever cartridge be, although because of the energy saving thermostatic fittings, especially if the The height of the thermostatic cartridges is no longer distracting, it is very much in vogue become. With a preferred combination of the one-hole fitting according to the invention with an intrinsically safe inlet and overflow set against back suction can also be used with free standing bathtubs on the annoying so-called free spout, a gooseneck Mixed water flow to the tub can be dispensed with.  

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

Fig. 1a, b and c

With the fixedly disposed within at the valve housing bottom 5 pipe 6, thread or such. B. connected with Loctite, could also be in one piece, the valve body cpl. formed, which is attached to the hole ϕ52, 2, in the upper bathtub edge 1 by means of the compensating piece with seal 4 and the nut 3 in the space between the rear of the bathtub and its tile covering. In the line of symmetry of the fitting is displaced in a cross shape parallel to the outside at the bottom of the lower housing part 5 at the threads 13, the four connections for preferably metal-mesh-coated pressure hoses for hot and cold water 19 for the passage 18 , 27 , 35 , 25 through the tub / shower conversion 34 Mixer cartridge 50 , 85 , 87 , 98 and the discharge of the mixed water, switchable by moving the pin 46 with the sealing plate 47 , after tub 39 , 40 , 16 , 14 or after shower 43 , 38 , 17 , 15 . The threaded core bores of the connecting threads 13 of 14 and 15 are transferred in the lower part 5 of the fitting housing by means of the conduit 16 and 17 according to the sealing image 26 at the bottom of the bath / shower conversion 34 , analogously to this for hot and cold water 19 , 18 . In the case of molded parts, the transitions are made by means of touching cores. At z. B. Maintenance, for this sb . Fig. 1c, the tub / shower changeover 34 is inserted into the tube 6 and then the thermostat cartridge 50 is attached. By means of the pressure ring 54 and the nut 55 , the opposing flange O-ring sealing images 23 on top 34 are down on the cartridge 50 , 25 , 25 , 24 and 26 tub / shower changeover bottom to bottom of the housing 5 , 16 , 17 and 2 × 18 pressed according to the principle actio = reactio. Specifically, these are at the bottom of the fitting housing, connecting the through-channels 35 by means of the connections 27 , flange O-ring grooves 30 with their edges 33 and the mixed water drains to the tub 28 and to the shower 29 ; at the top of the pan / Shower-- conversion 34/23 anschlissen the hot and cold water ports 25 of the mixer cartridge 50 and connection of the mixed water waste stream 24 of the cartridge 50, the initiation switch chamber 41 after the 42nd

Course of water

Hot and cold water flows from the bottom 26 of the fitting housing 5 , coming from the conduits 18 via the through channels 27 , 35 in the tub / shower conversion 34 after the mixer cartridge 5 , or to the connections 25 thereof ; Hot and cold water comes as mixed water, deflected from the cartridge 5 in the cartridge 5 by 180 degrees and enters the bath 41 / shower switchover, or in the switchover chamber 42 , at the inlet 41 above. In the illustrated, non-actuated position of the pin 46 , with which the sealing plate 47 is firmly connected, this seals 47 at the NHA ring 49 , which is in the wall 38 with the O-ring 37 , the transition to the chamber 43 after rejection 38 after shower 17 , 15 and the mixed water thus flows from the changeover chamber 42 to the bore 39 and thus emerges from the tub / shower conversion 34 at the bottom out of the discharge channel 40 , with the flange O-ring seal image 26 after the transition 16 after connection, outlet 14 after tub off. If the sealing plate 47 at the NHA ring 49 in the wall 48 closes the outlet after the bore 39 by pressing against the force of the spring (not shown) of the so-called self-switching bath / shower changeover 34 , the mixed water flows through the chamber 43 and the Discharge 38 , O-ring groove 32 , after the transfer 17 and so to the outlet 15 , at the bottom of the fitting housing 5 , after a shower.

After inserting the tub / shower diverter 34 and the mixer cartridges 50 and pressing their seals, sealing images 26 and 23 , the spring steel wire clip 62 is inserted into the tube 6 from above, for this purpose the 62 one-piece driving pins 63 must be pressed inwards , these, after releasing, threaded or threaded through the double-sided cutouts 8 in the tube 6 , then snap into the analog driving bores in the outer rotating ring 64 . The connecting hollow shaft 21 can then be plugged onto the hollow shaft 53 of the cartridge 50 and then connected to the catch 21 on and into the tube 6 of the fitting housing, the rotating ring 57 , with its actual knob 58 , for actuating the tub / shower Changeover, with the sides because of the spring clip 62 being threaded into the two-sided, one-piece with 57, two ribs 61 for taking the bracket 62 or its driving pins 63 ; Finally, the central rotary handle 60 is placed on the axis 52 of the thermostatic cartridge. The rotating ring 57 is tight on the inside of the housing tube 6 , but not drip-proof, the same applies to 21 in 57 and the central entrainment from 60/52 to 21. No splash water should get into the free housing 6 , 5 interior 84 In the event of leaks at the two flange O-ring seals at the top 23 and bottom 26 on the bath / shower diverter 34 or on the cartridge 50 , 52 , 53 itself, the leakage water should be above, above the nut 3 can exit under the gags 58 , 59 , 60 to the upper edge of the bath tub 1 to be made aware of the defect; due to the NHA rings 78 and 2 × 65, any leakage water cannot escape into the space between the back of the bathtub and its tile covering.

On the valve body 6, 5 external, inaccessible mechanism for the changeover Tub after shower

To the force or the torque of the return spring 83 of the toggle 58, 57 after shower is manually by approximately 50 degrees rotated, the driving ribs 61 rotate the spring steel wire clip 62, and so is the driving pins 63 on outer casing pipe 6 of the rotary ring 64, 68 , 69 twisted. The three round bars 70 , 69 offset from one another by 120 degrees thus rotate the link plate (s) 72 , 73 , which is mounted at the bottom of the bearing collar 10 of the lower housing part 5 with the link plates 72, 73 ring segments 75 ; in one piece with these 72, 73 are the slide tracks 74 at the top and bottom, which easily slide the vertical pin 77 on the additional actuating pin 76 inserted in the NHA ring 78 when drilling into the housing interior 5 , 84 and thus horizontally with these 76 and push it. The vertical pin 77 is always kept perpendicular by the two or in the two elongated holes 80 in the guide part 79 . When the toggle switch 58 , 57 is released , the spring 83 always returns it to the original tub position, even when the tub / shower changeover is held by the mixed water pressure, pin 46 with sealing plate 47 ; in this position, the additional actuating pin 76 is always fully pulled out of the tube 6 inner diameter, so that the tub / shower changeover 34, the pin 46 of which is not always pressed in the direction of the tub by the known spring not shown, does not project beyond its 34 outer diameter, well from the fitting housing 5 , 6 , 84 can be seen above the tub rim 1 . Cartridge 50 and tub / shower conversion 34 could u. U. for possibly pulling out together, fully moveable with each other with an easily detachable mini pull rope connected to each other. Due to the fact that practically everything 50, 34 and 2 × 19 lies in a line of symmetry, it would also be conceivable at the bottom between the transitions 18 and the connections 19 for the metal-fabric-coated pressure hoses. B. in vorst. EP, there item no., Which, when the hold-open pins after loosening the nut 54 and thus pushing up the tub / shower changeover and the cartridge, no longer hold the balls open to enable maintenance without water shut-off, conceivable. The ball hold-open pins would be inserted through 34 in through holes.

Fig. 2

Here, with a slightly lower overall height of the fitting, the thermostatic cartridge 87 with wax expansion element 51 and single-lever setting 88 is used.

In order to get a desired ball segment over the nut 3 , over the upper bathtub rim 1 and also over the toggle 58 , center point of the ball single-lever pin 88 bearing in 87, the pin 88 becomes the extension 89 at the top, as is the case on the market existing valve, with miniaturized system separator, known in front of the overflow hole in the tub. The rotary knob 91 has the large bore 92 in the center for rotating and pivoting the single-lever pin 88 , 89 . The screwed onto the extension 89 , 88 in a known manner spherical lever 90 runs tightly, but not drip-proof, on the calotte 93 , the z. B. is attached to the top of the tube end 6 . One is also conceivable. U. additional, sleeve-like, or on the top of the rotary knob 91 , around its free space bore 92 tightly sliding, also sealed to the pin 88 sealed to the interior 84 of the valve housing 6 , 5th
