Definitions

  • the invention relates to a water heater.
  • Water heaters are known in practice, in which the heat required for heating the water is provided by a gas burner of the water heater.
  • the gas burner is supplied via a gas line, a gas stream, wherein the size of the gas stream can be adjusted via a gas valve integrated into the gas line of the water heater.
  • the size of the gas burner supplied gas flow is proportional to the size of the water flow of the water to be heated. In this case, the larger the water flow of the water to be heated is the gas flow supplied to the gas burner, the larger.
  • a current or voltage to Operating the control device can be provided by a generator which is integrated in a water pipe of the water heater and generates electricity or voltage for operating the control device from the flow energy of the water to be heated. Voltage for operating the controller is provided only when the water heater is supplied with a water stream for heating. On the other hand, if no water flows through the water heater, then the generator also provides no current or voltage for operating the control device.
  • the present invention is based on the problem to provide a novel water heater, at the controller even then settings can be made when the same is not traversed by water.
  • the water heater according to the invention comprises a rechargeable battery and a charging circuit for the rechargeable battery, wherein the charging circuit charges the battery only when the provided by the integrated water generator in the water heater heater power is greater than that for operation of the control device required electricity is. Adjustments can also be made to the control device of the water heater if the same is not passed through by water. The required power is provided by the battery.
  • the charging circuit for the battery ensures that even if the battery is completely drained or short-circuited, the operation of the controller and thus the water heater is not affected.
  • the charging circuit comprises at least one transistor, a resistor and preferably two diodes, wherein an emitter-base circuit of a transistor is connected in series with a Zener diode or acting as a Zener diode shunt regulator, and wherein this series connection in parallel is connected to the control device.
  • a collector-base circuit of the transistor is also connected in series with the Zener diode or shunt regulator, said series circuit is connected in parallel with the rechargeable battery.
  • the present invention relates to a water heater not shown in detail for heating a water flow from an actual temperature to a desired temperature, wherein the heat required for heating the water is provided by a gas burner.
  • the gas burner of the water heater is supplied with a gas stream via a gas line of the water heater.
  • a water stream to be heated is supplied to the water heater via a water pipe thereof.
  • the size of the gas stream to be supplied to the gas burner is adjustable via a gas valve integrated in the gas line of the water heater.
  • the water heater in particular the same integrated gas valve in the gas line is modulating controllable by means of a control device 10, wherein a current for operating the control device is provided by a generator acting as a current source, which is integrated into the water line of the water heater.
  • a generator acting as a current source, which is integrated into the water line of the water heater.
  • Such a generator is also referred to as a hydrogenerator and is not shown in Fig. 1.
  • the integrated into the water pipe generator generates from the flow energy of the water to be heated, a current for operating the control device, which is an alternating current.
  • the alternating current provided by the latter can be converted into a direct current which serves to operate the control device 10.
  • the rectifier circuit 11 in the embodiment shown comprises two diodes 14 and 15 and two capacitors 16 and 17, wherein a first input 12 of the rectifier circuit 11 between the two diodes 14 and 15 and a second input 13 thereof between the two capacitors 16 and 17 attacks. It should be noted that the rectifier circuit 11 shown in FIG. 1 is purely exemplary and any rectifier circuit can be used.
  • a battery 18 is assigned to it, which is designed as a rechargeable battery.
  • a charging circuit 19 is connected according to the invention, wherein the charging circuit 19 only charges the battery 18 when the current generated by the generator is greater than the current required for operation of the control device 10.
  • the charging circuit 19 ensures that even when the battery 18 is completely discharged or short-circuited, the operation of the controller 10 is not affected.
  • the charging circuit 10 is formed by a transistor 20, a resistor 21 of a diode 22 and a Zener diode 23, wherein instead of the Zener diode 23, a shunt regulator acting as a Zener diode can be used.
  • the transistor 20 is designed in the illustrated embodiment as a PNP transistor, wherein an emitter-base circuit between the emitter E 20 and the base B 20 of the transistor 20 is connected in series with the Zener diode 23, in such a way that the cathode of the Zener diode 23 at the base B 20 of the transistor 20 attacks.
  • This series connection of the emitter-base circuit of the transistor 20 and the Zener diode 23 is connected in parallel with the control device 10. Parallel to the emitter-base circuit of the transistor 20, the resistor 21 is connected.
  • a collector-base circuit of the transistor between the collector C 20 and the base B 20 of the transistor 20 is also connected in series with the Zener diode 23, said series circuit of the collector-base circuit of the transistor 20 and the Zener diode 23 is connected in parallel to the rechargeable battery 18.
  • the diode 22 is connected between the collector C 20 and the battery 18, the diode 22 with its anode at the collector C 20 of the transistor and with its cathode at one pole, namely at the positive terminal, the rechargeable battery 18 attacks ,
  • the negative pole of the battery 18 and the anode of the Zener diode 23 are connected to a ground potential 24.
  • the charging circuit 19 for the rechargeable battery 18 functions such that when a larger current is generated by the generator connected to the inputs 12 and 13 of the rectifier circuit 11 than is required to operate the control device 10, this excess current turns on the transistor 20 opens, so that the excess current can be supplied via the collector C 20 of the transistor 20 and the diode 22 of the battery 18 for charging the same.
  • the larger the excess current provided by the generator the more the transistor 20 opens, and the more current flows toward the battery 18. This ensures that even when the battery 18 is completely discharged, only the current is used to charge it. which is not needed for operation of the control device 10 and thus is surplus.
  • the transistor 20 closes, so that in this case too, the operation of the control device 10 is not impaired.
  • the current supplied to the operation of the control device 10 and thus the voltage provided by the same is therefore independent of the state of charge of the battery 18. Then, when the generator generates no current and thus no voltage for operation of the control device 10, the voltage in the battery 18 stored electrical energy can be used to operate the control device 10 and at the same z. B. make settings.
