Definitions

  • the invention relates to a fitting for a continuous water heater according to the preamble of the first claim.
  • Such fittings for continuous flow water heaters are available in various designs. They serve to control the gas flow to a burner of a heat exchanger depending on the water flow.
  • a gas fitting for a burner-heated water heater described on the upstream side has a main gas valve which is connected to a flow meter.
  • the main gas valve is followed by a water shortage valve, which is connected to the flow meter.
  • the water shortage valve is in turn connected downstream of a thermostatically controlled valve connected to an evaluation circuit.
  • EP 1 170 549 A2 is a gas-fired water heater with a burner heated by a heat exchanger known, which is preceded by a water valve in a water switch and the gas side gas valves are connected upstream, one of which is controlled by the water switch and another of a gas pressure controlled servo valve. While a downstream of the servo valve upstream gas adjustment valve is actuated via a first handle, the water valve can be actuated via a second handle.
  • a similar structure has a in the published patent application DE 100 30 118 A1 described gas-fired continuous water heater on. Again, there are two handles, via which the operation of the continuous flow water heater takes place.
  • the invention is based on the problem in a fitting for a continuous flow water heater according to the preamble of the first claim to ensure a simple and clearer manual operation by only one control element must be pressed. Due to the reduction in the openings through the housing wall of the valve at the same time the risk of the occurrence of leaks is reduced. Furthermore, the production cost should be minimized.
  • a switching element is rotatably mounted on the protruding from the water-bearing spindle spindle, wherein a rotational movement of the control element via driver on the switching element is transferable.
  • This switching element furthermore has a switching contour, via which a permanently arranged microswitch can be actuated.
  • an electronic ignition and monitoring device is electrically controlled, via which by means of an electrically controllable valve, the gas flow to the burner can be shut off.
  • valve when the serving to shut off the gas flow via the control valve is formed by the electronic ignition and monitoring device associated servo valve.
  • a simple and secure way to transmit the rotational movement of the operating element to the switching element can be realized in that the driver is formed by one or more controls located on the ribs, which protrude into slots located on the switching element.
  • the switching element is connected via latching hooks with the operating element.
  • a control valve and a main valve are housed among other, known in the art and therefore not further explained components.
  • the main valve is controlled by a well-known to those skilled electronic ignition and monitoring device 3, also known as a so-called automatic burner, which is connected to the gas part 2.
  • the control valve is controlled via a transmission 4, which transmits the water flow-dependent movement of a water in the water part 1 water membrane from the interior of the water-bearing housing 5 to the outside and then from there into the gas-carrying housing 6 of the gas part 2 to the control valve.
  • a venturi and a presetting which allows the adjustment of the water flow to a predetermined value according to the supply conditions.
  • This presetting member also serves as a temperature corrector, i. It allows the manual compensation of fluctuations in the chilled water temperature.
  • a spindle 7 connected to the presetting member projects out of the water-bearing housing 5, on which a control element 8 is mounted.
  • a switching element 9 is rotatably mounted on the protruding from the water-bearing housing 5 spindle 7, wherein a rotational movement of the control element 8 via a driver on the switching element 9 is transferable.
  • the driver is formed in this embodiment in a favorable manner by a plurality of the control element 8 located axial ribs 10 which project in them associated with the switching element 9 axial slots 11 protrude.
  • control element 8 and switching element 9 facing latching hooks 12 which ensure a reliable connection.
  • the switching element 9 further has a switching contour 13, via which a fixedly arranged in this embodiment, the gas-conducting housing 6 microswitch 14 can be actuated.
  • the microswitch 14 is electrically connected to the electronic ignition and monitoring device 3.
  • FIGS. 1 and 2 an embodiment of a valve according to the invention for a continuous flow water heater is shown in the off state.
  • the operating element 8 is in the off position.
  • the switching element 9 is rotated so far that the switching contour 13 has released the button 15 of the microswitch 14.
  • the gas supply to the burner is thereby shut off and regardless of a water removal at a water heater downstream of the water tap this remains in the off state.
  • control element 8 To turn on the valve, the control element 8 must be turned so far that it is in the possible adjustment range for adjusting the water flow or the manual compensation of the fluctuations of the cold water temperature, as it is for example in the Figures 3 and 4 is shown.
  • the gas supply to the burner of the heat exchanger is opened via the electronic ignition and monitoring device 3 and the gas is ignited.
  • the burner remains in operation until no water is removed.
  • the continuous water heater remains operational and can be put back into operation by renewed removal of water.
  • the operating element In order to switch off the continuous water heater manually, the operating element is moved beyond the setting range possible for setting the water flow to the off position; like in the FIGS. 1 and 2 shown. As already explained above, thereby the gas supply to the burner is shut off regardless of an occurring water withdrawal.
  • the fitting according to the invention for a continuous flow water heater is of course not limited to the illustrated embodiment.
  • the off position is reached only by overcoming a the end of the adjustment range signaling, but überfiberbaren detent to accidentally at a desired adjustment of the water flow or a manual compensation for the fluctuations of the cold water temperature off Position.
