Definitions
- the invention relates to a once-through water heater according to the preamble of claim 1.
- a "warm start” function in which one in the water heater arranged small memory is kept at an adjustable temperature in order to Tap hot water very quickly to provide hot water at the tap can.
- the aim of the invention is to avoid these disadvantages and a once-through water heater to propose the type mentioned, which is simple in structure and easy to use distinguished.
- the proposed measures result in a significantly simplified operation of the Device. This means that both the outlet temperature and the Storage temperature can be set. It also ensures that there are none inconsistent settings of the setpoints comes.
- the features of claim 2 have the advantage that also on a switch for on and Switching off the "warm start” function can be dispensed with. This function can be done by the two Target value transmitters are taken over in connection with the flip-flop.
- one of the threshold switches e.g. switch through when 90% of the setting range is exceeded and the other threshold switch if the value falls below 10% of the maximum setting switch through, whereby the flip-flop is set or reset.
- FIG. 1 shows a circulating water heater 30 which is heated by a burner 31 Has heat exchanger 32.
- the heat exchanger 32 is provided with a pump 33
- Return line 34 fed with water, which after heating by the heat exchanger of one with a temperature sensor 35 provided flow line 36 is discharged.
- the line 36 leads to one Collective heating system, not shown, branches off from it a line 37 leading to a heating water / process water heat exchanger 38 leads to a via a heat exchanger return line 39
- Changeover valve 40 leads, which is connected via a line section 41 to the pump 33 on the return side.
- the temperature sensor 35 is connected to a regulating / control device 43 via a measuring line 42, which is connected via a line 44 to an electromagnet 45 of a gas valve 46, which in A gas line 47 to the burner 31 is arranged.
- a control device 43 With the control device 43 is about a line 48 connects a motor 49 to the pump 33.
- Another line 50 leads to one Electromagnet 51, which influences the switching valve 40 via a lever 52, which on the Line section 41 facing away via a line 53 with the previously mentioned heating system connected is.
- the heating water / process water heat exchanger 38 is penetrated by a tap 54 which can be closed with a nozzle 55.
- the nozzle 54 is connected to the pipe coil with a Cold water network 56 connected.
- a Temperature sensor. 57 is provided, which is connected to the control and regulating device 43 via a measurement line 58 connected is.
- a setpoint generator is provided, which is in the form of a variable resistance is executed.
- the center connection 21 of the target value transmitter 15 is each an input of two comparators 4, 6 connected via connecting lines 22, 23.
- the second input of the comparator 4 is not connected via a connecting line 8 to one shown, the temperature of the hot water sensor and the second input of the Comparator 6 is via a connecting line 10 with a temperature, also not shown, the temperature connected in a small memory sensor.
- the connecting line 23 is connected to a further connecting line 24 via which one Connection of the center connection 21 of the setpoint generator 15 to the inputs of two Threshold switches 17 and 18 is made.
- the threshold switch 17 turns on when the set target value is more than 90% of the maximum possible target value.
- the Threshold switch 18 switches through when the target value set with the target value transmitter 15 is less than 10% of the maximum possible target value.
- the outputs of the comparators 4 and 6 are via connecting lines 5 and 7 with a logic 13 connected. This is also the output Q of a flip-flop 16 via a connecting line 12 connected. The inputs of the flip-flop 16 are connected to the outputs via connecting lines 19 and 20 the threshold switch 17 or 18 connected.
- the logic is via a control line 14 with auxiliary units, not shown, for a burner, such as Gas valve, blower and the like connected
- the setpoint generator 15 If the setpoint generator 15 is set to over 90% of the maximum possible value during operation, then gives the threshold switch 17 a signal and sets the flip-flop 16, whereby the logic 13 in the Operating mode "warm start” is set.
- the logic ensures that the burner is not tapped Process water is kept or put into operation so far that the temperature in the Small memory is kept at a value corresponding to the set target value. It has to are not necessarily the setpoint specified for the hot water temperature, but it can be a value derived from this according to a specific algorithm act.
- the threshold switch 18 outputs a signal to the flip-flop 16 and resets it, whereby the operating mode "warm start” is switched off.
- the operating mode "warm start” is activated by a, even if only briefly Exceeding 90% of the maximum possible setpoint when setting the setpoint.
- the setpoint generator 15 can be used to switch the "warm start” operating mode on and off, as well as the specification of the setpoints for the temperature of the hot water and the small storage tank respectively.
