Definitions

  • the invention relates to a control circuit for the blower motor of a vacuum cleaner according to the preamble of claim 1.
  • control circuit is known from international patent application WO 87/01921.
  • this control circuit requires a large number of technically complex components, such as, for example, integrated control circuits and special flip-flop elements.
  • the invention has for its object to carry out a control circuit of the known type with simpler components without having to accept a loss of control accuracy and tax security.
  • the frequency of the supply voltage is supplied to the timing element, from which the timing element derives its counting pulses.
  • the time period until a signal appears at the outputs of the timer depends on the frequency of the supply voltage.
  • An independent of the frequency of the supply voltage always the same time until the pulses are delivered in that the timer is provided with a frequency generator generating the counting pulses.
  • other time intervals corresponding to powers of two are also possible for the output of the signals at the two outputs of the timing element.
  • the automatic resetting of the control circuit to the power level or speed level set on the potentiometer when the vacuum cleaner is started up or put back into operation after being switched off during suction work is achieved in a simple manner by the reset input of the first flip-flop element being connected to the positive pole via a pulse capacitor the DC supply voltage of the control circuit is connected.
  • a control circuit 1 with a control circuit which acts on a line stage 3 lying in series with the blower motor 2 of a vacuum cleaner.
  • a main switch 4 is used to switch the vacuum cleaner on and off.
  • To generate the DC voltage required for the control circuit 1 is one of the series circuit of a Zener diode and a diode and an existing rectifier component 5 connected to their common connection point connected to a common RC element, which is followed by a smoothing capacitor 6.
  • 7 is the positive pole and 8 the negative pole of the DC circuit.
  • the positive pole 7 is also connected to the one pole of the AC voltage circuit feeding the blower motor 2.
  • a timing element 9 and first and second flip-flop elements 10 and 11 are connected to the DC voltage circuit with their supply connections. Furthermore, the LED 13 of an optocoupler 14 is connected to this DC voltage circuit via a control transistor 12.
  • the power stage 3 has a triac 15 which is in series with the blower motor 2.
  • a potentiometer 17 is provided in its control circuit 16, with which a limiting resistor 18 is in series. This limiting resistor can also be integrated in the potentiometer 17.
  • the switching path 19 of the optocoupler 14 lies parallel to the potentiometer 17 and the limiting resistor 18.
  • the timing element 9 has an integrated frequency generator which generates the necessary counting pulses.
  • the frequency generated by the frequency generator can be varied by appropriate connection with RC elements 20.
  • the timer 9 also has a start input 21 and a first and second output 22 and 23. At these outputs 22 and 23, an output signal appears at different times after the start of the timer 9, the output signal at the first output 22 earlier than at the second Exit 23 appears.
  • the output signal of the first output 22 of the timing element 9 is fed via a first capacitor 24 to the reset input R of the first flip-flop element 10 and the output signal of the second output 23 via a second capacitor 25 to the reset input R of the second flip-flop element 11 .
  • the control circuit also contains a control circuit 26 which can be briefly connected to the positive pole 7 of the DC voltage circuit via a manually operable switching element 27.
  • the timing element 9 with its start input 21 and the two flip-flop elements 10 and 11 with their set inputs S are connected to this control circuit 26.
  • the connection of the set input S of the second flip-flop element 11 to the control circuit 26 is indicated by dashed lines. Since it may be cheaper to supply this flip-flop element 11 with the set signal with a delay compared to the set signal of the first flip-flop element 10, the set input S of the second flip-flop element 11 can be via one belonging to an RC element Coupling capacitor 28 are connected to the non-inverting output Q of the first flip-flop element 10.
  • the base of the control transistor 12 is also connected to this output.
  • the control circuit 26 of the switching element 27 is also via a blocking diode 29 with the inverting output Q connected. The blocking diode 29 is with its forward direction to the inverting output Q directed.
  • the control circuit 1 works as follows: By closing the main switch 4, the supply voltage U, which is, for example, a 220 V AC voltage, is switched on. In this case, a pulse capacitor 31 is charged with its one connection to the positive pole 7 and with its other connection via a decoupling diode 30 to the reset input R of the first flip-flop element 10, and thereby gives a reset pulse to the first flip-flop element 10 This ensures that the control circuit is switched back to its initial state each time the vacuum cleaner is switched on or on again. In this initial state, the control transistor 12 is blocked and the bridging of the potentiometer 17 and the limiting resistor 18 by the switching path 19 of the optocoupler 14 is ineffective.
  • the supply voltage U which is, for example, a 220 V AC voltage
  • the triac 15 is accordingly in accordance with the respective setting of the potentio meters 17 modulated.
  • the blower motor 2 can thus be controlled via the potentiometer 17 up to a speed predetermined by the limiting resistor 18 and corresponding to the permissible continuous output of the blower motor 2.
  • the switching element 27 is actuated so that the timing element 9 has a start pulse at its start input 21 and the two flip-flop elements 10 and 11 at their set inputs S receive a set pulse each.
  • the second flip-flop element 11 can also receive its set pulse with a delay via the non-inverting output Q of the first flip-flop element 10. These set pulses cause an H signal to be present at the non-inverting output Q of each flip-flop element 10 and 11.
  • the control transistor 12 is turned on by the H signal present at the output Q of the first flip-flop element 10, so that the light-emitting diode 13 receives voltage and the switching path 19 is controlled into the conductive state by its emitted light. So that the potentiometer 17 and the limiting resistor 18 are bridged, so that the triac is fully controlled and the blower motor now runs at the highest speed.
  • An output signal appears at the first output 22 of the timing element 9, which is started simultaneously when the switching element 27 is actuated, after a specific, predetermined time. This output signal is forwarded via the capacitor 24 as a pulse to the reset input R of the first flip-flop element 10.
  • the first flip-flop element 10 is reset again, so that an L signal appears at its non-inverting output Q. This leads to the control transistor 12 being blocked.
  • the light-emitting diode 13 of the optocoupler 14 goes out and the switching path 19 returns to its non-conductive state.
  • the potentiometer 17 and the limiting resistor 18 are thus again effective in the control circuit 16 of the triac 15.
  • a corresponding blocking is provided in the control circuit so that a renewed increase in output on the blower motor 2 can only take place after the recovery time has prevented it from overheating.
  • the blocking happens as follows: By actuating the switching element 27, the second flip-flop element 11 has also received a set pulse. This set pulse causes an H signal at the non-inverting output Q of the second flip-flop element and at its inverting output Q an L signal is present. The presence of an L signal at the inverting output Q of the second flip-flop element 11 means that the control circuit 26 is short-circuited via the blocking diode 29. If the switching element 27 is actuated during this time, the pulses thereby triggered become due to the short circuit of the control circuit 26 with the inverting output Q of the second flip-flop element 11 is not effective.
  • the circuit is also provided with the usual interference suppression circuits consisting of capacitors, diodes and resistors, which are generally known and therefore need not be described in more detail here.
