Definitions

  • the invention is based on a gas-heated Water heater, especially instantaneous water heater, after the Genus of the main claim.
  • a viewing opening is on Housing arranged to the ignition process or the Observe the combustion process based on the flame formation can.
  • the presence of a flame in gas heaters by means of monitoring an ionization electrode is, for example known from document JP 62 288 418 A.
  • the gas-heated water heater according to the invention draws is characterized in that by using an electrical Operating display for flame detection on the aforementioned Viewing window can be dispensed with.
  • Such Operating display can be implemented with simple means, while inserting a viewing window into the Housing jacket of the water heater and in the front the combustion chamber wall considerably more manufacturing effort means.
  • a viewing window for the Flame detection can be used for the device jacket Water heater a closed and attractive design be selected, which is similar to that of electrical appliances.
  • the water heater has a known ionization flame monitoring, whereby the operating display according to the invention for flame detection depending on Ionization current signal is switched.
  • the electrical operating indicator lights up, e.g. an LED display, green on, so that the user of the proper operation of the gas heated Water heater is signaled.
  • the electrical operating display for flame detection is advantageously in integrated into a module that in addition to the operating display, a charge status display for Batteries that are responsible for the power supply and an input and Power switch includes.
  • a design improvement is brought about by the three aforementioned elements are arranged behind a hinged flap of the control panel. It points the flap opens a window behind which the operating display and the Charge status display for the batteries is still visible despite the closed flap are arranged.
  • Figure 1 shows schematically the housing jacket of a gas-heated water heater an operating display for flame detection
  • Figure 2 shows a device diagram Water heater with the functionally relevant components.
  • a housing jacket 10 is one Gas flow heater shown in the lower Area a control panel 12 is provided.
  • the Control panel cover 12 has a gas slide 14 with which the gas supply to a burner 16 is opened or closed can be.
  • a Water quantity selector 18 arranged in the form of a rotary knob.
  • There is also an electrical one on the control panel cover 12 Operating display 20 for flame detection, one Charge status indicator 22 for batteries and an input and Switch 24 provided for the power supply, the arranged in a battery box 26 batteries of the Serve power supply.
  • the three elements 20, 22, 24 are arranged behind an operating flap 28, a window 29 also in the closed state the view of the electrical operating display 20 for flame detection and the electrical charge status indicator 22 for the batteries leaves free.
  • the device has a water flow line 30 by a Water inlet 32 through one as a whole with reference number 34 provided water valve and a heat exchanger 36 to one Warm water outlet 38 or leads to a nozzle.
  • a Water inlet 32 through one as a whole with reference number 34 provided water valve and a heat exchanger 36 to one Warm water outlet 38 or leads to a nozzle.
  • Below the heat exchanger 36 is not in one Combustion shaft of the gas burner 16 shown arranged from a gas line 40 with fuel gas is supplied.
  • One is in the gas line 40 as a whole the gas valve provided with the reference number 42.
  • the Gas fitting 42 has a gas valve 44, which via a Pilot gas pipe 46 is connected to a pilot burner 48.
  • a membrane 50 is also located in the gas fitting 42 arranged in cooperation with a second Gas valve 52 of the gas fitting 42 in the gas line 40 arranged first main gas valve 54 controls. At the Gas fitting 42 is also a membrane 50 bypassing Bypass line 56 arranged to the second gas valve 52nd leads. In the gas line 40 is a second main gas valve 58 arranged, depending on the position of the Throttle valve 14 releases the gas path.
  • Water fitting 34 the structure and mode of operation of which is known and is not described in more detail here, the constancy of the Outlet temperature of the heated water reached by over a arranged in the gas line 40 and with the Water fitting 34 related control valve 60 a guided in proportion to the flow rate of the water Quantity of gas reaches burner 16.
  • the outlet temperature of the Water are changed.
  • At the pilot burner 48 is still an ignition electrode 62 and a flame monitoring electrode 64 arranged.
  • the gas-heated Water heater has a control unit 66, which over corresponding control or supply lines with the electrical components, including your own Power supply to the battery box 26, in connection stands.
  • the operating display for flame detection works in the following way:
  • the operational readiness of the gas-fired water heater is produced by using the slide switch 24 the control device 66 is supplied with voltage.
  • the control device 66 When opening a nozzle on the water outlet 38 is at the Water valve 34 arranged microswitch 68 closed and output a voltage signal to controller 66.
  • First gas valve 44 in gas fitting 42 is opened.
  • the first main gas valve 54 is closed, while the gas valve 52 is open so that gas from the Gas line 40 via the bypass line 56 into the pilot gas pipe 46 arrives and flows to the pilot burner 48, where it with the help the ignition electrode 62 is ignited.
  • the ionization flame monitoring electrode 64 reports the ignition to the Control unit 66, which now closes the gas valve 52.
  • the electrical operating display 20 is activated at the same time, which are green throughout the process of hot water extraction lights up, and thus the user the proper Operation of the water heater signals.
  • the microswitch 68 will Voltage signal to control unit 66 interrupted.
  • the first Gas valve 44 is closed and second gas valve 52 will be opened. This causes the differential pressure at the Membrane 50 removed and the first main gas valve 54 closed.
  • the flame on the burner 16 extinguishes, causing simultaneously via the monitoring electrode 64 to the Control unit 66 a signal to switch off the electrical Operating display 20 is issued.
