  • the present invention relates to a vacuum cleaner with electronic control of the total power according to the preamble of claim 1.
  • suction systems are known to which an outlet is attached.
  • the operator can plug an electrical load into this socket.
  • a tool e.g. B. an orbital sander. If you now set the suction system to the "Automatic" switch position, the vacuum cleaner remains in a so-called “standby mode”.
  • An electronic circuit inside the vacuum cleaner now monitors whether an electrical current flows through the socket, which is the case when the consumer is started up. As soon as the consumer is switched on at the socket, the electronics turn on the naturally aspirated engine. If the operator has now connected the suction hose to his tool, the dust generated by his tool is extracted from the suction system. If the tool is switched off, the naturally aspirated motor is also switched off by the electronics after a short run-on time. This function is also known in specialist circles under the name "automatic switch-on”.
  • the object of the present invention is therefore to provide a vacuum cleaner with electronic control of the maximum total power, which makes it possible, depending on the power consumption of at least one working device, to regulate the power consumption of at least one suction device in such a way that the maximum available power consumption electrical connection power is not exceeded, so that the devices remain in operation.
  • an electronic control of the maximum total power of electrical consumers on a common supply line is used, which ensures that the power of at least one of at least two electrical consumers is regulated so that the total power consumed by the total connected consumers does not exceed the maximum load value of the supply line increases from the network.
  • the regulation does not limit at least one consumer in the power consumption until the value for the maximum available power consumption in the network is reached.
  • the invention further has the following features.
  • the vacuum cleaner is switched to automatic mode using the main switch. As long as none of the buttons
  • the system remains without any recognizable function. If the tool is now switched on, flows through a converter connected to this circuit a current that induces a secondary voltage. This secondary voltage is converted into a DC voltage proportional to the tool current via a peak value rectifier.
  • This DC voltage is now fed to an AD converter input of a microprocessor.
  • the microprocessor now converts the DC voltage into a digital register value.
  • the microprocessor then queries its inputs. Based on the set value for the maximum current consumption (e.g. 10 A, 13 A, 15 A or 16A) in the system, which can be specified using a selector switch, the processor can now set its target value of the maximum permissible current via the connecting cable (e.g. 16A in Germany).
  • the maximum current consumption e.g. 10 A, 13 A, 15 A or 16A
  • the processor can now set its target value of the maximum permissible current via the connecting cable (e.g. 16A in Germany).
  • the microprocessor calculates the maximum permissible current that the suction turbine may take in order not to exceed the maximum connected load available. He then determines the phase gating time T1 for a triac for power regulation for the aspirator. He then determines the zero crossings of the mains voltage by querying the relevant input. It thus synchronizes with the mains voltage.
  • the processor now waits for the calculated phase gating time T1 and ignites the triac. As soon as a current flows through the triac and the naturally aspirated motor, a secondary voltage is induced in a further converter. A second peak rectifier generates a DC voltage proportional to the suction motor current. The microprocessor measures this voltage and adds the value to the measured socket current. Is that If the result of the addition above the specified setpoint at the switch, the phase gating time T1 is reduced step by step. The naturally aspirated engine consumes less power and the total power is also reduced. The processor now continuously measures the DC voltage of the naturally aspirated motor current and the socket current, processes both and adds the two values, then compares the result with the maximum permissible total power consumption and regulates the suction turbine power accordingly.

  • Fig. 1 shows a circuit arrangement for regulating the power consumption of suction systems with integrated power supply for tools
  • Figure 1 shows in general that a vacuum cleaner can be connected to a network 1, which can be operated by means of a suction motor 3 or two suction motors 3, 4 or more than 2 suction motors.

  • a current measuring element 9 is arranged in the power line, which in the exemplary embodiment shown is designed as an inductive tapping element.
  • other current measuring elements can also be used, such as e.g. B. a Hall element, a capacitive coupling or other taps, so that the current in the network is detected on the input side in front of the suction motor.
  • the current tapped at the current measuring element 9 is fed to a current limiter 10 as an input variable, with a 16 in the area of this line 16 Resistor bridge or bridge elements can be arranged to set the current limiter 10 to the maximum current that can be supplied, depending on the country and the desired current limitation of 10, 13, 15 and 16.
  • the output of the current limiter 10 acts via the control line 8 on the power regulator 5, which accordingly limits the power for the vacuum motor 3.
  • a tool 14 is switched into the line via the connection socket 12 and the tool switch 13, then the current flowing into the device from the network 1 is measured via the current measuring element 9, and if this current is above the set value, the control line is used 8, a corresponding control pulse is given to the power controller 5, which then correspondingly reduces the total current available through the suction motor 3.
  • the current limiter 10 can regulate the output of an individual suction device 3, 4, ... or all of them together accordingly.
  • this automatic switch-on 11 it is determined on the basis of the current measuring element 18 whether a tool is connected to the connection socket 12 and is in operation. If this is the case, the automatic switch-on 11 switches on the suction device via the line 15 by starting a corresponding start impulse from the line 15 to the current limiter 10 and then switching the power regulator 5 through the line 8. However, this switching only takes place via the maximum desired power switched on in line 16.
  • the purpose of the measure is therefore always to ensure that the vacuum cleaner connected to an electrical network does not overload the network and triggers the mains fuse.
  • the current limiter 10 is connected to a corresponding selector switch 17 at a corresponding input.

Abstract

L'invention concerne un aspirateur d'impuretés doté d'une régulation électronique de la puissance totale. L'invention est caractérisée en ce que la puissance d'au moins un consommateur électrique d'un minimum de deux est régulée de telle sorte que la somme des puissances captées par la totalité des consommateurs branchés ne dépasse pas la valeur maximale de charge de la ligne d'alimentation du réseau. En outre, ladite régulation ne limite pas la puissance captée par au moins un consommateur, tant que la valeur maximale de puissance disponible dans le réseau n'est pas atteinte.
