Definitions

  • the present invention relates to a hot water heater.
  • DE 43 08 770 C2 shows a hot water heater with one by one Burner D heated heat exchanger with a cold water inlet and a Hot water outlet is connected, and with a the fuel supply to the burner B controlling controller C, which is connected to a temperature sensor in the hot water outlet is connected, a between the cold water inlet and hot water outlet Bypass channel is arranged.
  • a hot water heater is known with a heated heat exchanger with a cold water inlet and a Hot water outlet is connected and with a heat supply to the Heat exchanger-controlling controller that connects the cold water inlet to a flow sensor and is connected to a temperature sensor in the hot water outlet, wherein between Cold water inlet and hot water outlet a bypass channel is arranged.
  • Hot water heater of this type In a known other hot water heater of this type is located in Cold water inlet a flow sensor, which is connected to a control unit for a burner connected. The cold water then runs to a heat exchanger below which the burner is arranged. Behind the heat exchanger and in the way to that Hot water outlet is a temperature sensor, which is also connected to the control unit connected. The desired temperature at the outlet is set by a setpoint device set on the control unit.
  • the known hot water heater described above has two main ones Disadvantage.
  • the temperature at the outlet drop as soon as the maximum heating power of the burner is reached.
  • the temperature at the outlet depends on the height of the water flow.
  • the maximum water flow must be limited when the temperature set point is set to a maximum. Furthermore, must to avoid the second disadvantage, the switch-on point of the burner at one higher water flow when the temperature is at a minimum temperature set point is set.
  • cold water is supplied to a cold water inlet 12.
  • Flow sensor 1 detects the flow of cold water when not shown on one Withdrawal point at a hot water outlet 13 removed warm water becomes.
  • the flow sensor 1 is connected to a control unit 3, to which a Adjustment button 18 e.g. a setpoint can be set in the form of a potentiometer.
  • the Control unit 3 is connected to a modulating gas inflow controller 2, the one Fuel gas feeds a burner 4.
  • the cold water inflow 12 is via a line 5 to a heat exchanger 7 connected in which the cold water is heated and via a line 10 to the Hot water outlet 13 is supplied.
  • a temperature sensor 11 detects the temperature of the warm water behind the heat exchanger 7 and is as an actual value transmitter to the Control unit 3 connected.
  • the burner 4 sits in a housing 6 below the Heat exchanger 7 and an overlying heating shaft is by a blower 8 or vented by natural draft.
  • the fresh air supply takes place via a tube 9, which is below of the burner 4 opens into the housing 6.
  • FIG. 1 there is a bypass channel 17 in FIG. 2 provided between the cold water inlet 12 and the hot water outlet 13, wherein the branch of the bypass channel 17 is upstream of the flow sensor 1.
  • flow restrictors 14 and 15 are arranged in the bypass duct 17 and in the cold water inlet 12 after the junction of Bypass channels 17 arranged flow restrictors 14 and 15, respectively.
  • an organ 16 regulating the flow rate e.g. in the form of a rooster intended.
  • the flow restrictors 14 and 15 are dimensioned so that the total fluid resistance the heating circuit and the bypass channel when fully open Flow control member 16 is the same size. However, this dimensioning is only exemplary and can also be chosen differently.
  • the structure of the hot water heater according to the invention described above results in the following mode of operation:
  • the water temperature is always regulated to the maximum setpoint by the temperature sensor 11 and the control unit 3.
  • the setting button 18 on the control unit 2 can be omitted.
  • the flow control member 16 When the flow control member 16 is closed, the entire water flow through the heating circuit 5, 7, 10, and the switch-on point of the burner 4 is determined by the flow sensor 1, as in the known case, which means that now the switch-on point in the same way as is specified in the known device.
  • the maximum water flow is limited by the flow limiter 15 so that the water temperature will not drop even when the hot water requirement is maximum. This avoids the first disadvantage mentioned at the outset.
  • the temperature setpoint moves between its minimum and maximum value, which is the same for the switch-on point of the Brenners applies.
  • the temperature of the Water controlled by the temperature sensor 11 and the result of the mixture. This leads to a stable temperature at the outlet 13.
  • the flow control element 16 specifies the temperature setpoint generator for the device.
