- the invention relates to a circuit arrangement for suction power control a vacuum cleaner
- DE-C-39 02 647 is an automatic device Suction power control of a vacuum cleaner known. At this device are two at different pressures responsive pressure switches provided, the switching pulses in corresponding to a connected control circuit Trigger functions. Because of the two pressure switches there is a "directional dependence" of the device, i.e. around to ensure proper functioning of the device, it must be at a lower and that at a higher pressure responsive pressure switches at a specific point the control circuit can be connected. It comes with the Assembly of the device to confuse this Connection options, then the device is inoperable. The use of two pressure switches also means an increased cost of materials.
- the invention has for its object a circuit arrangement to control the suction power of a vacuum cleaner train that only one pressure switch is required and thus achieved an easier assembly and also a Inoperability of the circuit arrangement by Incorrect assembly is avoided.
- This task is in a circuit arrangement according to the Claim 1 solved.
- the control signal can be adjusted by hand of a potentiometer can be changed, whereby one constant power corresponding to the potentiometer setting of the blower motor is specified.
- automatic Control can be changed by the pressure switch. Through the corresponding to the respective pressure conditions Opening and closing the pressure switch is between two for the control signal predetermined voltage values back and forth switched here, so that in the manner of a two-point control Blower motor is controlled in its output so that a constant or at least approximately constant vacuum is produced.
- the comparator consists of one There is operational amplifier, at one input an sawtooth voltage synchronized with the mains voltage of the blower motor lies and at the other input the control signal is fed.
- the network synchronous Sawtooth voltage with the control signal can be controlled by a Change the control signal in a simple way flawless, the performance of the blower motor accordingly changing control of the semiconductor switching element to reach.
- Low-noise ignition pulses for the controllable semiconductor switching elements can be generated by the output of the operational amplifier via a differentiator with the an input of a comparator is connected to the other input has a fixed reference voltage.
- the control signal can be operated manually Potentiometer or on the other hand using one to one Resistance of pressure switch connected in parallel changed become. In the latter case, there is an automatic Regulation of the negative pressure. Because of the respective negative pressure dependent opening or closing of the pressure switch the parallel resistor either on or off, so that the control signal between two voltage values commutes. Accordingly, the performance of the Blower motor increased or decreased, so that on average a constant or at least approximately constant negative pressure sets.
- a switch can advantageously be provided with between manual adjustment using the potentiometer and automatic vacuum control can be switched can.
- the power control of the blower motor is expedient due to additional resistances in the control signal circuit minimum and a maximum value limited.
- the blower motor starts gently after switching on achieved in a simple manner in that by means of a series RC element an additional signal in the feed connector of the Control signal is fed to the comparator.
- This member controlling the semiconductor switching element 2 is like can be seen from FIG 2, a control transistor 9, the Base 10 via a first control line 11 with the Ignition pulse part 8 is connected.
- the power section 4 contains also a circuit part 12 for generating a DC supply voltage.
- the circuit part 12 points to this a series RC element 13 to which two diodes 14 lie antiparallel in row.
- the two diodes 14 are with their other connection side to one pole each Smoothing capacitor 15 connected.
- To that Smoothing capacitor 15 is also a Zener diode 16 for Voltage stabilization connected in parallel.
- the most Smoothing capacitor 15 applied voltage represents the DC supply voltage for the circuit arrangement.
- the power section 4 also contains one at the supply voltage of the blower motor 1 lying first voltage divider 17, at the tap of a filter capacitor 18 with its a connection pole is connected. Through this filter capacitor 18 may be in the divided AC voltage contained DC voltage components suppressed. On the other connection pole 19 of the filter capacitor 18 is the Synchronous part 5 connected.
- the synchronizing part 5 has one of a first and a second Operational amplifier 20 and 21 existing window comparator on.
- the AC voltage supplied by the filter capacitor 18 is to the inverting input of the first Operational amplifier 20 and on the non-inverting Input of the second operational amplifier 21 placed.
- With the two operational amplifiers are located at their other inputs 20 and 21 via divider resistors 22 on the DC supply voltage.
- switched Window comparators occur at every zero crossing AC voltage present at its output 23 narrow Rectangular pulses. Through these impulses one becomes with his Collector-emitter path to a via a series resistor 24 connected to the DC supply voltage Capacitor 25 charging transistor 26 connected in parallel controlled.
- controlled discharge transistor 26 becomes the capacitor 25 periodically over a lying in the collector-emitter circuit Discharge resistor 27 discharge. During the blocking period of the Discharge transistor 26 is charged again in each case Capacitor 25. This creates a sawtooth voltage educated. This sawtooth-shaped voltage is on the inverting input of a comparator Operational amplifier 28 placed. The non-inverting Input of this operational amplifier 28 is via a second Control line 29 is supplied with a control signal.
- a differentiator 31 is connected, whose output 32 with the inverting input one Comparator 33 is connected to its non-inverting Input by means of a second voltage divider 34 a Reference voltage is set.
- the output 35 of the comparator 33 is connected via the first control line 11 to the base 10 of the Control transistor 9 connected.
- the control section 7 (FIG 4) contains a third voltage divider 36, at the tap 37 a potentiometer 38 and the Parallel connection of a control resistor 39 with a Pressure switch 40 is connected.
- the one from the control resistor 39 and the pressure switch 40 existing parallel connection is also connected to ground via a control RC element 41.
- Via a switch 42 the tap of the Potentiometer 38 or the common connection point 43 of the Control resistor 39 and the pressure switch 40 with the Control RC element 41 via a connection resistor 44 to the Control line 29 are switched.
- a limiting resistor 45 connected with its one connection pole, whose other terminal is connected to ground. With the control line 29 an additional control part 46 is connected.
- This additional control part 46 contains a series RC element 47 and one of a fixed resistor 48 and a PTC resistor 51 existing voltage dividers.
- the tap of the series RC link 47 and the voltage divider is in each case one Decoupling diode 49 or 50 with the control line 29 connected.
- the circuit arrangement works as follows: If the vacuum cleaner is switched to the mains voltage by means of a switch (not shown), then the required DC supply voltage is provided via the circuit part 12. Via the first voltage divider 17 and the filter capacitor 18, an AC voltage which is lower than the mains voltage but is synchronous with it is available. As already described, a sawtooth voltage which is synchronous with the AC voltage is generated by means of the window comparators 20 and 21 and the discharge transistor 26 controlled by them by correspondingly charging and discharging the capacitor 25. A "high" signal is generated at the output 30 of this operational amplifier 28 by this sawtooth voltage at the inverting input of the operational amplifier 28 acting as a comparator.
- This "high” signal remains until the sawtooth voltage reaches the value of the control signal present at the non-inverting input of this operational amplifier 28. At this moment, the output signal of the operational amplifier 28 changes to "low". As a result of this signal change, the differentiator 31 generates a narrow needle pulse.
- the needle pulses emanating from the differentiating element 31 are converted by the comparator 33 into corresponding narrow rectangular pulses, which represent the control pulses for the control transistor 9 and are supplied to the base 10 of the control transistor 9 via the first control line 11.
- the control transistor 9 is turned on for the duration of such a rectangular pulse and thus fires the semiconductor switching element 2 each time.
- That of the operational amplifier 28 acting as a comparator supplied control signal can be adjusted in different ways or be specified.
- the setting of this control signal can be done by hand using the potentiometer 38 become.
- the blower motor 1 is defined Power controlled as a result of being fixed by the potentiometer 38 predetermined control signals on the acting as a comparator Operational amplifier 28 always at the same phase the sawtooth voltage the signal switching at its output 30 takes place.
- the semiconductor switching element 2 always with the same potentiometer setting corresponding phase angle ignited.
- the switch 42 in its other switching position and switched to the common connection point 43, so the control signal is now specified by the Pressure switch 40 and the control resistor 39.
- the response pressure of the pressure switch 40 is reached, this closes.
- the Control resistor 39 bridges and the voltage of the control signal elevated. This leads to a later ignition of the Semiconductor switching element 2, so that the motor power drops.
- the pressure switch 40 opens again and thus switches the control resistor 39 a.
- control part 7 is due to the resistance part connected to ground of the third voltage divider 36 is a minimum value the voltage on the blower motor.
- the limit on a maximum value of the motor voltage is given by the Limiting resistance 45.
- the additional control part 46 still a starting current limitation and causes overtemperature protection.
- For starting current limitation serves the series RC element 47 of the control part 46.
- About the capacitor of this series RC element 47 is in Switch-on instant of the vacuum cleaner the voltage of the control signal raised so that the firing angle of the semiconductor switching element increases and thus the starting current is reduced.
- the voltage of the Control signal With progressive charging of the capacitor of the series RC element 47, the voltage of the Control signal, which is a reduction in the ignition angle of the Semiconductor switching element 2 and thus an increase in Engine performance.
- Overload protection is provided by a fixed resistor 48 and a PTC resistor 51 existing voltage divider of the Control part 46 reached. With appropriate heating of the Blower motor 1, the resistance of the PTC resistor 51 rises on. Reaches the voltage at the tap of this voltage divider 48; 51 a higher value than the voltage of the second Control line 29 pending control signal is via the Decoupling diode 50 this higher voltage in the second Control line 29 effective. This leads over to the comparator acting operational amplifier 28 and this downstream controls to enlarge the Firing angle of the semiconductor switching element 2 and thus too a reduction in the power of the blower motor 1.

Wird der Staubsauger mittels eines nicht dargestellten Einschalters an die Netzspannung geschaltet, dann wird über den Schaltungsteil 12 die erforderliche Versorgungsgleichspannung bereitgestellt. Über den ersten Spannungsteiler 17 und den Filterkondensator 18 steht eine gegenüber der Netzspannung niedrigere, jedoch mit dieser synchrone Wechselspannung zur Verfügung. Wie bereits beschrieben, wird mittels des Fensterkomparators 20 und 21 und dem durch diesen gesteuerten Entladetransistor 26 durch entsprechendes Auf- und Entladen des Kondensators 25 eine mit der Wechselspannung synchrone Sägezahnspannung erzeugt. Durch diese am invertierenden Eingang des als Vergleicher wirkenden Operationsverstärkers 28 liegende Sägezahnspannung wird am Ausgang 30 dieses Operationsverstärkers 28 ein "High"-Signal erzeugt. Dieses "High"-Signal bleibt solange bestehen, bis die Sägezahnspannung den Wert des am nicht invertierenden Eingang dieses Operationsverstärkers 28 anliegenden Steuersignales erreicht. In diesem Augenblick wechselt das Ausgangssignal des Operationsverstärkers 28 auf "Low". Infolge dieses Signalwechsels wird durch das Differenzierglied 31 ein schmaler Nadelimpuls erzeugt. Die von dem Differenzierglied 31 ausgehenden Nadelimpulse werden durch den Komparator 33 in entsprechende schmale Rechteckimpulse umgewandelt, welche die Steuerimpulse für den Steuertransistor 9 darstellen und über die erste Steuerleitung 11 der Basis 10 des Steuertransistors 9 zugeführt werden. Der Steuertransistor 9 wird jeweils für die Dauer eines solchen Rechteckimpulses durchgesteuert und zündet damit jedesmal das Halbleiterschaltelement 2.
