Definitions

  • the invention relates to an automatic switch-on for a suction device, in particular for a vacuum cleaner, the motor of the vacuum cleaner being switched on and off depending on a connected implement.
  • an automatic switch-on from DE-OS 38 22 633 is known, which is provided for a secondary device in the form of a vacuum cleaner for an electric hand tool, and includes a phase control for the motor of the vacuum cleaner, which a predetermined start-up delay of the vacuum cleaner motor when switching on as Main unit designated electrical hand tool allows.
  • a built-in socket for the implement is arranged on the vacuum cleaner, which receives voltage through a switch position A (AUTO) of a manual switch via a relay contact of the automatic switch-on, a shunt being arranged in the current branch to this built-in socket is, the voltage drop after amplification via an amplifier arrangement switches another relay, which applies voltage to the motor of the vacuum cleaner via a make contact, and that the circuit board of the automatic switch-on additionally has a vacuum membrane button, which is located at the input of another amplifier arrangement, which the first relay switches, this vacuum membrane button is connected to the intake air flow in the suction line of the vacuum cleaner and, when the vacuum value is exceeded due to filter contamination, this relay is switched, causing the changeover contact to turn the current on building socket interrupts.
  • AUTO switch position A
  • the essence of this invention is therefore that, on the one hand, the associated work tool is first switched on and off without taking into account the suction power of the vacuum cleaner by arranging a shunt in the power branch to the work tool, the voltage drop of which is amplified, as a result of which a normally open contact of a relay connects the vacuum motor to the Mains voltage sets.
  • the vacuum cleaner motor is switched on via a voltage drop at a shunt. After switching off the assigned implement, the voltage drop at the shunt disappears, which means that the vacuum cleaner is also switched off via a relay. Switching the vacuum motor on and off via the voltage drop on a shunt can be used in conjunction with amplifiers vanishingly small hysteres can be made very precisely.
  • the circuit board of the automatic switch-on additionally has a vacuum membrane button, which is located at the input of a further amplifier arrangement, which switches the relay located with the contacts in the current path to the working device, this vacuum membrane button with the intake air flow in the suction power in the Suction line of the vacuum cleaner is connected and, when the vacuum value is exceeded due to filter contamination, this relay is switched, which causes the changeover contact to interrupt the current path to the built-in socket.
  • the filter performance of this vacuum cleaner is consequently included in the connection or disconnection of the associated implement, with the result that the associated implement is switched off when the filter is dirty.
  • the changeover relay in the event of an interruption in the current path to the built-in socket due to filter contamination via the changeover or changeover contact leads voltage via a corresponding resistor to the input of an amplifier arrangement, as a result of which the current path leads to the suction motor Switching relay remains switched through despite the loss of voltage via the shunt and the vacuum cleaner motor thus continues to operate, a signal lamp being switched on at the same time via the button.
  • the automatic switch-on 1 is shown in the assembled state on the upper part of a vacuum cleaner, with the cover removed.
  • the automatic switch-on 1 is connected to a manual switch S2 and a built-in socket X3.
  • An interference filter L1 / C1 is also provided for the feed line of the vacuum cleaner.
  • the fan of the motor M1 is located in the immediate vicinity of the automatic switch-on 1, as can be seen from FIG .
  • the mode of operation of the automatic switch-on 1 results from the detailed circuit according to FIG. 2 in conjunction with the overview circuit according to FIG. 3.
  • FIG. 3 shows a device switch S2 which has three switch positions.
  • the vacuum motor M1 starts immediately.
  • a vacuum membrane button P1 which is attached to the circuit board of the automatic switch-on 1, is connected to the mains voltage via the connection X8. If the filter fogging exceeds the value set on the vacuum membrane push button P1, a signal light H1 connected to X5 and X1 lights up. The suction motor M1 continues to run.
  • the built-in socket X3 for an additional power tool connected to X2 and X7 is de-energized in the "MAN" switch position.
  • the built-in socket X3 In the "AUTO" position, the built-in socket X3 is immediately live, while the suction motor M1 is still stationary.
  • the vacuum membrane push button P1 is also connected to mains voltage via X10 according to FIG. 2. If the power tool connected to the built-in socket X3 is now switched on, a current flows through the shunt R23 located between X1 and X2, which produces a voltage drop across it.
  • This voltage drop is amplified electronically via amplifier IS1, T1 and leads to the attraction of the relay K1 arranged on the automatic switch-on 1.
  • this relay K1 now connects X3 to X4 according to FIG. 3, as a result of which the vacuum motor M1 receives mains voltage and starts up.
  • the suction motor M1 also stops after the relay K1 has dropped out.
  • Relay K2 picks up continuously, goes into latching mode and interrupts the mains voltage from X3 to socket X3 via X7 via the changeover contact. Subsequently, the line voltage from X3 to R9 forwarded to the amplifier electronics via the amplifier IS1, T1, as a result of which K1 is continuously tightened. This additional circuit therefore replaces the missing voltage at the shunt R23, which keeps the vacuum motor running.
  • This self-maintenance or locking can only be canceled by switching off the suction device, which is achieved by setting the switch to "ZERO".
  • This locking function also serves the safety of the worker, since otherwise when the power tool starts uncontrolled after the vacuum is released, for.
  • B. solve a suction hose blockage the health of the worker would be at great risk.
  • the switch-off of the socket X3 was delayed further in order to stop the power tool in the event of a brief increase in the vacuum z.
  • B. Avoid kinking the hose.
  • the suction motor M1 can also be started in the "AUTO" switch position by the contacts X11 and X12 according to FIG. B. flow switch with reed switch and magnetic float.
  • the vacuum motor is switched off with a time delay in the control range (approx. 10 seconds).
  • An additional RC element (C9 plus R24) is provided for this.
  • the power tool if the set vacuum value is exceeded for a longer period is switched off, this being indicated to the operator by an additional signal light connected to X16 and X1. In this way, the operator can ensure that the power tool is not defective but has been switched off by the vacuum cleaner due to a lack of suction power.
  • an additional relay module 2 with a bistable toggle relay can be connected via X14 and X15, which further improves the safety shutdown or automatic switch-on.
  • An inadvertently switched on power tool cannot start unintentionally when the suction device is switched on by switch S1 in the "AUTO" position. In this case, a warning lamp lights up on the suction device. This additional locking must be deleted with an acknowledgment button; only then can the combination consisting of a vacuum cleaner and an additional power tool be started.
  • an additional vacuum membrane button P2 on the circuit board of the automatic switch-on can be put into operation.
  • AUTO2 another switch position (AUTO2) on device switch S2 means that X9 is connected to the vacuum membrane button P2 via X9.
