Definitions
- a device for burner control is known in which, depending on the state of a medium to be heated, a measurement of the burning time and the total cycle time, the burning power is controlled in order to operate the burner at the most favorable operating point .
- burners can now also be retrofitted which, for example, have only one power level.
- the pause time has an externally adjustable, reciprocal ratio to the burner's duty cycle.
- Such an oppositely variable pause time can be easily achieved by programming a maximum pause time that is a constant multiple of the respective burner on time is shortened. If the burner is switched on for a longer period of time, this even reduces the pause time to '0', which means that the burner's full heating output can be used.
- This bridging contact can also be a thermostat contact, which falls below a minimum temperature of z. B. 16 ° C closes.
- Figure 1 shows the functional diagram of a previous temperature control between two fixed temperatures T1 and T. As soon as the room temperature drops below the value T1, the burner or the heater is switched on until the temperature T is reached. Then the thermostat switches off and so on.
- the switch-on times can be very short and numerous.
- Figure 2 is a corresponding functional diagram for a device according to the invention.
- FIG. 3 shows the schematic circuit diagram of a break control according to the invention.
- the burner (1) is switched on by the thermostat contact (2) via the normally closed break contact (4).
- the time control (6) receives the information via line (7) that the burner (1) is switched on.
- the control ends (6) the time measurement of how long the burner (1) was on.
- the timer (6) actuates the pause contact (4) via the relay (5), opens it and thus prevents the burner (1) from being switched on again.
- FIG. 4 shows the course of the burner's switch-on time and the pause time T p derived therefrom.
- the pause time (cycle time) is also reduced by one minute of the pause time.
- the point (11) in FIG. 4 at the intersection of the straight lines T p and T Br means that in this example the pause time T p has shrunk to '0' after twenty minutes of burning time.
- FIG. 6 schematically shows the structure of a digital time control which is able to implement the pause circuit shown in FIG. 1.
- Such a timing can, for. B. from a digital time pulse generator (16) and a pulse counter (17).
- the time pulse generator (16) is, for. B. designed so that you can select time pulses after 60,45,30 or 15 seconds to feed them to the pulse counter (17).
- the time pulse generator (16) is reset to '0' after the maximum time of 60 seconds.
- the maximum number of pulses at which the breaks can be ended and the burner can be switched on again by the thermostat (2) is set on the pulse counter (17) using the adjusting knob (8).
- the number of maximum pulses can be read off the display (19).
- the current number of pulses which have elapsed in the respective cycle can also be read on a second display (18).
- the relay (20) receives voltage via line (7) and switches the contact (22), which has the task of switching the cycle times, to line (25) and thus via the selector switch (9) to one of the shortened cycle times, for example as shown to a 30-second cycle, ie twice as fast as the basic cycle time 60 seconds.
- the relay (20) no longer receives any voltage. It falls off and the contact (22) connects the pulse counter (17) via line (24) and (26) with the basic cycle time of 60 seconds. At the same time, the relay (5) picks up and opens the break contact (4).
- the pulse counter (17) from the clock generator (16) is supplied with pulses every 60 seconds until the number of pulses shown on the display (19) (in this example '40') is reached. At this maximum number of pulses, the pulse counter (17) is also set to '0', the relay (5) is de-energized and the break contact (4) closes.
- the burner (1) can only start operating again now, even if the thermostat (2) had previously closed.
- FIG. 5 shows the course of a control curve as can be achieved with the circuit of FIG. 6.
- Time t is plotted again horizontally, the number of corresponding time pulses plotted vertically. In this example, too, a preselected maximum number of pulses of 40 pulses is assumed.
- the duplication constant K 1 is also retained. This corresponds to a pulse sequence twice as fast during the burner's switch-on time, i.e. 1 pulse in 30 seconds.
- FIG. 5 shows a steep increase during this burner running time, which is assumed to be 15 minutes, up to 30 pulses corresponding to line 26.
- the time counting according to line 27 runs slowly with one pulse per minute during the remaining time (pause time T p ), until the preselected maximum pause time Pm is reached at 40 pulses.
- FIG. 5 also shows, for example, the possibility of driving a variable-capacity two-stage burner. e.g. B. full and half power.
- the pulse counter (17) of the time control (6) has a further setting option.
- a number of pulses (31) can be set, at which the control checks whether the burner is still switched on, according to item 29 in FIG. 5. If this is not the case, this means that less than half Burner power is required in the control cycle and the time control (6) gives the command to switch over to half the power via the command line (32) (see circuit diagram in FIG. 6).
- the burner receives the command to run with higher power via the command line (32).
