Definitions

  • the present invention relates to a gas-fired continuous water heater according to the introductory part of the independent claim.
  • Such water heaters have become known by marketable devices of the owner. These are constructed so that in the waterway, coming from the cold water network, first a so-called water switch, which operates on the Venturi principle and contains a constant water flow regulator, via the actuator of the regulator, a bypass to Venturi nozzle is provided by an adjustable valve is mastered. On the water switch follows in the waterway, the actual heat exchanger of the water heater and finally the nozzle. The heat exchanger is heated by an atmospheric gas burner having a mechanical, resettable by a spring gas valve which is directly directly driven by a rod of the water switch, wherein the position of the rod corresponds to the water flow rate. Thus, the gas flow rate is tracked to the cold water flow rate. So this is a device temperature control.
  • the gas burner is associated with a pilot burner, this ignition electrode and a thermoelectric ignition fuse having a second valve, which is connected in series with the above-mentioned dependent on the water switch gas valve in series or an electronic ignition device, which causes a heat request, the 2nd valve opened and the burner is ignited.
  • a water flow which is a corresponding Gas flow rate is tracked so that the user receives water of relatively constant temperature.
  • the water constant flow controller in the water switch keeps the water flow constant, so that the water outlet temperature is actually variable only with the gas pressure and the water inlet temperature. However, since these two quantities are relatively constant, there are hardly any fluctuations in the water outlet temperature.
  • gas-heated continuous water heaters without water switches and without constant water flow regulators, in which a temperature sensor is clamped on the outside of the hot water outlet of the heat exchanger.
  • This sensor measures the temperature of the outgoing warm water and sends a corresponding temperature signal to an electronic controller, which compares the current actual temperature value of the outgoing water with an adjustable setpoint value and varies the gas flow rate according to the determined system deviation.
  • the gas valve is designed here as a solenoid valve, so that the strength of the current given to the solenoid valve as the output of the controller determines the gas flow rate.
  • the setpoint of the outlet temperature can be adjusted by a potentiometer z. B. be changed in the range of 40 to 60 °.
  • This embodiment has the disadvantage that, at a relatively low set temperature (eg near 40 °), it can not be kept constant in the range of small water flow rates, since the heat output from the burner can not be arbitrarily reduced for functional reasons. If the so-called fürzündgasstrom of the burner is exceeded, the burner no longer burns at all gas-air mixture outlet slots, so that there is a risk that unburned gas enters the combustion chamber, which can lead to explosions.
  • This disadvantage was countered by the fact that the light-off water flow rate of the device electronically to the setpoint of Water flow rate was coupled, so that at low preselected water outlet temperatures small water flow rates are not possible because the device does not start.
  • a water heater with a waterway with heat exchanger and a parallel bypass is known.
  • a temperature sensor downstream of the connection of the waterway and the bypass the outlet temperature of the water heater is measured.
  • a controller controls a valve which regulates the distribution of water flow through the waterway and the bypass channel. This control valve consumes electrical energy and is subject to wear.
  • the post-published EP 990 861 A2 shows a water heater with a waterway with heat exchanger and a parallel bypass.
  • the bypass line In the bypass line is a controllable throttle valve.
  • a temperature sensor detects the temperature in the waterway downstream of the heat exchanger. In the device, the temperature at this temperature sensor is always controlled to the maximum setpoint. If a lower water temperature than this high temperature at the tapping point is desired, then this temperature should be adjusted by mixing cold water through the bypass line. This has the consequence that no small bleed with low outlet temperature can be tapped.
  • the water is always heated by the heat exchanger in the waterway to the maximum allowable temperature. Due to the associated higher exhaust gas losses, this would have a worse efficiency than a need-based adjustment of the temperature would have.
  • the present invention has for its object to avoid the disadvantages of the known device solutions.
  • a gas-heated continuous flow water heater 1 has a heat exchanger 3 which is heated by an atmospheric gas burner 2 and which lies in the region of a combustion chamber 4, which is covered at the top by an exhaust gas collection hood 6 provided with an exhaust gas connection 5.
  • the gas burner 2 is fed by a gas line 7, in which a solenoid valve 8 is arranged, which is dominated by a continuously adjusting electromagnet 9, which is actuated via a line 10 by an electronic controller 11.
  • the heat exchanger 3 is on the one hand connected to a leading away from a cold water source 12 cold water line 13, which is a series circuit of a trained as rempligelradgeber water flow meter 14 and a flow restrictor 16 inserted, on the other hand leads from the heat exchanger 3 equipped with a temperature sensor 17 hot water tap line 18 off their conclusion is dominated by one or more nozzles 19. Trained as a temperature-dependent resistor temperature sensor 17 is connected via a line 20, the water flow meter 14 via a line 21 to the controller 11.
  • a bypass line 24 is inserted, which is a series circuit of a throttle valve 25th , which can be adjusted via a handle 26, between the value "fully closed” and the maximum opening value and a further second flow restrictor 27, which can be preset via an adjusting member 28.
  • the two Wasser gutficientbeskyr 16 and 27 are preset such that the water limiter 16 is in series with the heat exchanger 3 is set to about one third of the water flow rate as the lying in the bypass line 24 further Wasser devisficientbeskyr 27.
  • the two horizontal curves 32 and 33 connecting the two curves 30 and 31 represent the limiting characteristics, the curve 32 being associated with the flow restrictor 16 and the curve 33 being the sum of the flow restrictor 16 and the flow restrictor 27.
  • the points 34 and 35 represent the limited maximum water flow rates through the cable run 13, or at the tapping point 19, the points 36 and 37, the intersections of the curved pieces 32 and 33 with the curve 31. Thus results in a hatched area 38, within the the gas-heated continuous water heater can be operated.
  • a water turquoise set of less than 2 I / min is not present, since the start-up water flow rate of the device is below. Operation of the device with smaller throughputs is impossible. Exceeding the point 34 with respect to the water flow rate is not possible because the max. Amount of water is limited by the flow restrictor 16.
  • a complete opening of the throttle valve 25 by operating the handle 26 causes an operating point on the curve piece 33 between the points 37 and 35. This means that when opening the throttle valve 25 with minimum device performance of the point 37 can not be driven under, because only at this water flow the device starts. Water flow rates of more than 19 l / min are not achievable, since both flow restrictors 16 and 27 cut off the water flows.
  • the hatched field 38 thus results in a field in which a stable and reproducible work of the water heater is possible at preselected water flow rates of the set temperature control.
