Definitions

  • the present invention relates to a gas-fired instantaneous water heater according to the introductory part of the independent claim.
  • Such gas-fired instantaneous water heaters are one with electronic control electric ignition on the market.
  • an electric battery has been used so far. These batteries have normal Operation has a lifespan of about a year, after which it exceeds need to be replaced.
  • This exchange causes for the consumer Additional costs and inconvenience to the extent that if he forgets the exchange, Problems with the operation of the instantaneous water heater, because this usually occurs does not start up properly. Furthermore, the environment is affected by the disposal of the Used batteries charged.
  • the present invention is based on the object just described above To avoid disadvantages and to create a gas-fired instantaneous water heater which no longer needs to replace batteries.
  • the figure shows a schematic diagram of a gas-fired once-through water heater.
  • the gas-fired instantaneous water heater 1 has one of one as the most important components atmospheric gas burner 2 heated fin heat exchanger 3, which in the course of a Waterway 4 is located, which is fed from a cold water source 5 Cold water supply line 6 and one leading away from the heat exchanger 3 Hot water tap line 7, in which a temperature sensor 8 is arranged and which of a nozzle 9 is controlled.
  • the heat exchanger 3 is arranged in a combustion chamber 10 by a Exhaust collector 11 is covered, to which an exhaust pipe 12 is connected.
  • the Gas burner 2 is fed from a gas line 14 provided with a solenoid valve 13, wherein the solenoid valve has an electromagnet 15 which with a line 16 with a control and regulating circuit 17 is connected. With this is also via a line 18 the temperature sensor 8 connected.
  • the burner is an ignition electrode 19 and one Monitoring electrode 20 assigned. Both are connected via lines 21 and 22 to one Automatic burner controls 23 connected. This controls the line 24 Electromagnet 15 and is via a line 25 from the control / regulation circuit 17th controlled.
  • This control and regulating circuit 17 is a via a line 26 Accumulator 27 assigned, which is connected via a line 28 to a further line 29 connected is. This is connected to an electric generator 30, which is connected to a rectifier 31 assigned.
  • the electric generator is driven by a shaft 32 by one Vane encoder 33 in the water path 4 and more precisely in the cold water supply line 6 is arranged.
  • the impeller 33 can also be used to control and Control circuit to communicate how high the actual value of the water flow is. this happens via a line 34.
  • the function of the gas-fired instantaneous water heater just described is as follows: When the nozzle 9 is closed, the entire device is at rest, the accumulator 27 is either charged, freshly installed or charged from the last start-up. When the nozzle 9 is opened, a certain water throughput is set depending on the degree of opening of the nozzle or a water flow limiter or water constant flow regulator located in the course of the water path 4. This water throughput is registered by the impeller 33 and initially acts on the control and regulating circuit 17 via the line 34. At this moment, the latter is supplied with electrical energy from the charged accumulator 27 via the line 26.
  • the control and regulating circuit 17 activates the automatic firing device 23 via the line 25, which activates the electromagnet 15 of the solenoid valve 13 via the line 24 and opens the solenoid valve.
  • the ignition electrode 19 is supplied with high voltage via line 21, so that sparks jump from the electrode to the burner in certain time cycles, which attempt to ignite the gas-air mixture flowing out of the burner 2. After ignition has taken place, a flame forms, so that the monitoring electrode 20 notifies this via the line 22 to the automatic burner control 23, which then keeps the electromagnet 15 of the gas solenoid valve 13 open via the line 24.
  • the automatic firing device 23 switches the electromagnet 15 to be de-energized via the line 24, so that the gas valve 13 closes .
  • the electrical supply of the automatic burner control 23 with electrical energy follows indirectly through the accumulator 27 via the line 26 and the control and regulating circuit 17.
  • the temperature controller integrated in the device consisting of the temperature sensor 8 as the actual value transmitter and the setpoint adjuster 35, which has a Line 36 is connected to the controller in the control and regulating circuit 17 and which energizes the electromagnet 15 via the line 16 is fed by the accumulator 17.
  • the impeller 33 drives the electric generator 30 via the shaft 32, so that it generates alternating voltage, which is rectified in the rectifier 31 and which feeds the control and regulating circuit 17 via the line 29, and in parallel thereto via the Line 28, the accumulator 27 is charged. Accordingly, an at least partially charged accumulator is always available at the start of the device, so that the control and regulating circuit 17 can start operating immediately without a certain amount of water having to have passed the device before the electric generator 30 driven by the impeller 33 is able to supply electrical power for commissioning.
