Definitions

  • the invention relates to a single-lever mixer Sanitary fitting according to the features of the preamble of the claim 1.
  • Sanitary fittings designed as single-lever mixers are known. They have the mixer taps that used to be common with two manually adjustable valves for cold and warm water largely replaced and usually consist of one Mixer tap with only one operating lever, which has a Control rod a control piston arranged in the mixer tap operated.
  • the operating lever is on both sides can also be swiveled vertically. While through the side Swiveling the mixture of cold and warm water is carried out by the vertical pivoting movement regulating the amount of water.
  • Single-lever mixer can also be operated without contact.
  • a sanitary fitting designed as a single lever mixer after The preamble of claim 1 is known from US-A-5,358,213.
  • this known single lever mixer however, one automatic operation to open the valve only in the closed End position of the operating lever possible because in all other manually set positions electrical opening allowing play between the actuators is canceled.
  • a sanitary fitting with two is manual adjustable valves for cold and warm water known with a solenoid valve turned on in the outlet channel is. This is done using a proximity switch a control electronics operated as soon as an object enters the monitoring area of the proximity switch. Apart from the not very attractive structure of such a non-contact controlled sanitary fitting at the Parts of the solenoid valve and electrical lines are good are mounted on the spout, this valve has the disadvantage that manual switching on and off, as with conventional manually operated fittings, is no longer possible. So the power supply drops of the solenoid valve for any reason, the armature no more water can be removed.
  • the invention is essentially based on the idea that Single-lever mixer tap an electrically controllable Downstream valve, its function not only by the Switching signals of the control electronics depends, but also on the position of the operating lever of the valve.
  • the control rod connected to the actuating lever and the electrically controllable valve mechanically coupled that the valve on the one hand despite the corresponding opening signals generated by the proximity sensor etc. remains closed, provided that the mixer tap is closed (the operating lever of the valve is located usually in its lower position).
  • the electrically controllable valve remains without a corresponding one Opening signals from the proximity sensor opened, if the mixer tap by operating the control rod is fully open (the valve lever is located usually in its upper position).
  • the mechanical control of the valve depending on the Reach the position of the control rod if it is electrically controllable valve around a known solenoid valve acts.
  • Such solenoid valves consist of a magnetic switching part and a mechanical valve part.
  • the magnetic switching part has one for opening and existing control pin to close the valve on by an electromagnet against the pressure of a spring is axially displaceable.
  • a permanent magnet provided the control pin after switching off of the electromagnet in its shifted against the pressure of the spring Holds position.
  • Control rod with the permanent magnet of the magnetic switching part mechanically connected via at least one lever. Becomes the axial position of the control rod changed, so it shifts the permanent magnet also changes and changes its distance with respect to the control pin of the switching part, namely such that in the closed position of the mixer tap the permanent magnet no longer has a functionally relevant effect exerts the control pin and in the fully open Position of the control rod of the permanent magnet the control pin constantly attracts.
  • the lever is designed as a lever, so that pulling the Control rod movement of the permanent magnet to the control pin towards, the mutual movement of Control rod and permanent magnet through one on the control rod arranged backdrop is set on which the sliding along one end of the bellcrank.
  • a major advantage of the single lever mixer according to the invention is that regardless of whether the fitting is operated without contact or in the event of a power failure is operated manually, the mixing function of the valve is not is affected.
  • Another major advantage is that the required with conventional single lever mixers Sealing by means of relatively expensive ceramic sealing washers is not necessary can. Because of the sealing function of the mixer tap in its closed position can be low requirements be put because of a perfect seal the downstream solenoid valve is responsible.
  • Fig. 1 denotes a single lever mixer, for example is attached to a sink 2.
  • the single lever mixer 1 is both with a cold water pipe 3 as also connected to a hot water pipe 4.
  • the single-lever mixer consists of a housing part 5 with a rigid Outlet 6 with outlet channel 7 and a head piece Operating lever 8.
  • the operating lever 8 is via an intermediate piece 9 and a control rod 10 with a Mixer tap 11 connected.
  • the control rod is 10 via a lever arrangement 12 with the permanent magnet 13 Solenoid valves 14 mechanically connected.
  • the water reaches the cold and hot water pipes 3, 4 via corresponding inlets into the mixer tap 11 there according to the position of one with the control rod 10 connected control piston (not shown) mixed and then passes from the outlet 15 of the mixer tap 11 via the Solenoid valve 14 to the outlet channel 7.
  • the solenoid valve 14 (see FIG. 2) is a known pilot valve, which acts as a switching valve is used. It consists of a magnetic switching part 16 and a mechanical valve part 17.
  • the switching part 16 contains a control pin 18, the lower one End extends into the valve part 17 and there one Pilot opening 19 of a piston 20 closes.
  • the upper The area of the control pin 18 is made from a sleeve 21 surrounded by non-magnetic material, which in turn is within the solenoid 22 of an electromagnet 23 is arranged.
  • the upper end face 24 of the control pin 18 is supported by means of a compression spring 25 on the sleeve 21.
  • the side facing away from the permanent magnet 13 is the lever arrangement 12 provided with a roller 29 on one the control rod 10 attached rotationally symmetrical backdrop 30 is present.
  • the backdrop essentially has three different ones Areas 31-33.
  • the liquid inlets and outlets of the solenoid valve 14 are designated by the reference numerals 35 and 36.
  • a proximity sensor 37 is provided (FIG. 1), which has a electrical line 38 connected to control electronics 39 is.
  • the control electronics 39 is in turn over others electrical lines 40 with both a power source 41, which is accommodated in the form of a battery in the head piece 8 is also connected to the solenoid valve 14.
  • FIGS. 3 to 6 of the single-lever mixer 1 according to the invention explained in more detail.
  • Figs. 4-6 Pivotal movement of the permanent magnet 13 by displacement of the magnet in the vertical direction.
  • the single-lever mixer 1 may be in its closed position Position. This means that the operating lever 8 (Fig. 1) pressed down and the mixer tap 11 is also closed.
  • the distance 42 of the permanent magnet is in this position 13 from the end face 24 of the control pin 18 of the Solenoid valves 14 (Fig. 4) chosen so large that the control pin 18 after switching off the electromagnet 23 not from the permanent magnet 13 can be held and by the spring 25 is pushed into its lower switch position.
  • the solenoid valve therefore only has a stable one in this case Position in which the control pin, the pilot opening 19 of the Piston 20 closes.
  • An electrical opening of the solenoid valve 14, for example due to disturbance variables (e.g. while on vacation), can not.
  • the control pen 18 After switching off the electromagnet 23 solely by the Magnetic force of the permanent magnet 13 against the restoring force held by the pen.
  • the control pin 18 is in his upper switch position and the valve is open.
  • the invention is of course not based on the above described embodiment limited. So, depending on Attachment of the operating lever to the control rod Execution of corresponding functions a reversal of the direction of movement the control rod, so that for actuation of the electrically controlled valve 14 the connecting lever 12 be adapted accordingly to this sequence of movements got to.
  • the proximity sensor and electronics not necessarily are a battery arranged in the head piece 8. Rather, a power supply can also be used, which for example, is integrated in the control electronics.
  • housing part with mixer tap and Valve and the outlet of the sanitary fitting are not mandatory be combined in one unit.
  • bathtub fittings it has proven to be advantageous to both fittings separately on the corresponding one adjacent to the tub Arrange room wall.
