Definitions

  • the invention relates to a fitting for bathtubs according to the preamble of claim 1.
  • the invention has for its object to construct a valve of the type in question so that it can be easily installed and removed in a tub and that it is possible to easily equip the valve with several comfort functions, such.
  • B. to give the possibility to install an automatic after-run for hot water and a safety device to prevent the sucking back of dirty water into the pure water network.
  • an essential idea of the invention is to be seen in the fact that the fitting is inserted from above into a fitting head part housing and into a housing for the lower part of the fitting with a finished drain underneath in one and the same line of symmetry, the fitting head part housing and the housing of the lower part of the fitting, preferably after the customer has set it Bathtub, have been aligned with each other by means of an empty mandrel provided before their final attachment to the two attachment points on the bathtub.
  • This bathtub hot and cold water mixing throttle and shower changeover valve with ready-made drain can, for. B. in a corner of a bathtub.
  • the mixing chamber and the shut-off valve for the valve are located below the upper tub rim and can be operated using several concentric adjustment handles.
  • a changeover bushing is provided, which is slidably mounted on the central tube and can be pushed into two positions using the adjusting handles on the tub edge. In the first position, the water coming from the mixing chamber flows from the central pipe into the switchover socket and then into the tub, in the second position from the central pipe into the switchover socket and then into the shower line leading to the shower.
  • the closure for the drain line from the tub to the channel is central in this installation shaft around the axis of symmetry and can, for. B. can be connected to the switch socket.
  • This closure preferably surrounds the changeover socket in the manner of a ring stopper and is actuated in synchronism with it. This then means that when the closure is open, the shower is always switched on when the self-closing valve in the enlarged head part at the top of the central pipe is open, while the drain for the bathtub is released when the drain line is closed.
  • a mixing chamber is preferably used in a bath fitting according to the invention, the mixing cone of which is adjusted by moving the central tube.
  • the temperature sensor for the mixer tap is preferably installed in the area of the lower end of the central tube and consists, for. B. from a stack of bimetallic plate springs, which are in contact with the tub water both when water enters the tub and when the tub is filled and mechanically move the central tube so that the set temperature for the mixed water is maintained when the tub enters.
  • This temperature sensor can also be used to open the shut-off valve of the mixer tap when the temperature of the tub water drops below a desired value, so that warm water is released. With servo support it is possible to move the mixing cone so that water is released at a temperature that is significantly higher than the set mixing temperature. At the same time, a corresponding amount of tub water can be drained off.
  • the arrangement of the entire fitting between a fitting head part and a fitting lower part housing also has the advantage that the central pipe can be designed as a real pipe separator, thereby preventing dirty water from being sucked back into the pure water network.
  • the pipe separator spring can, for. B. can be integrated directly into the adjustment handles, so that in the event of a return suction through these pipe separators the central pipe is separated and the rest of the dirty water can flow into a free outlet leading to the sewer.
  • the entire fitting can be easily installed and removed; as a compact unit, it is inserted into the two housings and can be used to clean the critical parts of the bath mixer be removed. In the latter case, the lower installation block with the drain to the sewer is also exposed, so that all cleaning work can be carried out and maintenance of the slip shower is also possible.

  • the changeover bushing 28 is also surrounded by a slide which can be displaced thereon in the form of an annular stopper 29 which closes or releases an outlet opening 30 to the channel 13.
  • the entire valve can be removed from the installation shaft after loosening the outermost control handle 21 after loosening fastening screws 115, which are rotatably held in a circular groove 114 in the valve head part housing 107, so that free access to the two installation blocks 5 and 6 and to slip -Shower is enabled. This is particularly important in order to be able to clean the individual channels within the lower installation block and to be able to maintain the slip shower.

  • the central tube 26, preferably under the extension part 100 or over the pressure spring 102 for the possible tolerance compensation of axial offsets between the valve head part housing 107 and the valve body housing 108, is axially decoupled from the finished process, i. that is, displaceable.
  • the length accuracy of the central tube is fully preserved.
  • 154 denotes the upper coupling piece with the groove for a flange O-ring 156, 155 a lower coupling piece, 157 a spring-loaded, axially slightly displaceable, length-constant connection.
  • the shut-off valve 25 of the mixer tap 24 is a normal diaphragm valve with a servo valve tappet 31.
  • a hydraulic, relapse-delayed time relay for the Control of the hot water let-off time in the servo valve 87, 89 is provided with a hydraulic, relapse-delayed time relay. After closing the tub closure 29, the shut-off valve 25 is then closed in a conventional manner.
  • the three concentric adjusting handles 21, 22 and 23 of the fitting 2 are recessed in the upper tub rim 47 in a cylindrical shaft 160 designed for this purpose.
  • This cylindrical shaft 160 is open with the U-shaped window 164 drawn into the tub rim 47 via the overflow edge 158 to the actual bathtub.
  • Vertical overflow channels 159 arranged in a star shape in the valve head part 53 lead the overflowing water from the overflow edge 158 through the valve head part 53 to the three overflow channels 134 into the space or shaft 4.
  • the overflow also takes place, as described above, with adjustment handles recessed into the tub rim via the communicating tube 20 which is connected to the bathtub via the circular tube 103 in the changeover socket 28. Since the previous overflow edge, ie the wall sleeve 20 to the overflow channels 134 at the level of the O-ring 106, would indicate that the bath water level was too low due to the lowering of the fitting head part 53, the transition between the communicating tube to the overflow channels 134 is additionally parallel to the Overflow channels 159 extending risers 161 pulled upward in the cylindrical shaft 160. The communicating tube is then additionally sealed to the fitting head part with the O-ring 162 and connected to the risers 161 via the windows 163.
