Definitions

  • the invention relates to a stirring device according to the preamble of claim 1.
  • a stirring device is known from EP 1835559 A1 known.
  • stirrers are also from the GB 2122396 A . US 6155113 A . US 4142804 A . EP 0124383 A1 and US 4606648 A known. Above all, such stirrers for laboratory use are often attached to a tripod, but such stirrers are also known with another associated holder or storage.
  • the invention provides to propose a stirring device according to claim 1.
  • the sensor is arranged on a circuit board arranged in the housing of the stirring device and used to control the drive motor. Thereby, the sensor can be directly included in the corresponding circuit and connected to this.
  • an expedient embodiment may be that the unbalance-responsive sensor is an acceleration sensor.
  • Acceleration sensors are known per se and can be purchased inexpensively and mounted in a simple manner on or in the stirrer.
  • the senor is provided with an audible and / or optical display or signaling device or controls such.
  • the user of the mixer can be warned acoustically or visually, if too much imbalance should occur.
  • the unbalance-responsive sensor is connected to the control of the drive motor and changes the speed of the drive motor when a limit value is exceeded, namely reduced or increased, or switches off the drive motor.
  • An expedient embodiment, in particular of the sensor, can provide that it is piezobased or inductively formed with a plunger coil or by means of a deflectable mass or by means of strain gauges. Sensors designed in this way have proved useful in detecting imbalances or vibrations, so that a corresponding use for the stirring device according to the invention represents an inexpensive solution.
  • An agitator is intended to be stirred with a stirring tool that can be introduced into a mass or liquid.
  • the stirring tool can be coupled with a chuck 2, which in turn is connected via a shaft 3 with a drive motor 4, so that after inserting a stirring tool in the chuck 2 by switching this drive motor 4 can be stirred.
  • the drive motor 4 is housed in a housing 5 enclosing it, on which outside an attachment point 6 is provided for fixing the stirring device 1 in the position of use. It can be seen in the embodiment on the rear wall 7 of the housing 5 as an attachment point 6 a provided with a fastening screw 8 console 9, which allows plugging the mixer 1 with this attachment point 6 on a horizontal arm 61 of a tripod.
  • an imbalance-responsive sensor 11 or a vibration sensor 11 is provided in the housing 5 of the agitator 1 arranged printed circuit board 10.
  • This is inventively arranged at the for the control or regulation of the drive motor 4. Alternatively, this can be arranged on a serving for the power supply of the drive motor 4 circuit board 10 and integrated into the circuit.
  • the sensor 11 may be piezobased or inductively formed with a plunger coil or by means of a deflectable mass or by means of strain gauges and, for example, be commercially available. It should be mentioned that, if appropriate, more than one sensor 11 could also be provided.
  • the stirrer 1 with a stir-in to be stirred mass or liquid agitator, with a stirring tool driving drive motor 4, with a drive motor 4 enclosing the housing 5 and with an attachment point 6 for fixing the stirrer 1 in the use position has at least one unbalance responsive sensor 11, which is preferably connected to the control or the control of the drive motor 4 or interconnected and turn off the drive motor 4 or can change its speed in case of unwanted or dangerous vibrations or vibrations.
