Definitions

  • the invention relates to a method for operating an attachment for a vacuum cleaner according to the preamble of claim 1. It further relates to a particularly suitable for carrying out the method attachment.
  • attachments for vacuum cleaners are well known. These are attachments with an electrically rotatable bristle roller and a motor to drive them, the z. B. be used for vacuuming carpets.
  • the bristle roller rotates in operation mostly in one direction;
  • methods are also known in which a direction of rotation of this bristle roller is reversed during operation, generally such that the bristle roller always rotates in a direction of movement of the attachment, thus facilitating movement of the attachment.
  • Such a method is z. B. from the DE 689 05 252 T2 or the EP 1 352 603 A1 known.
  • An object of the invention is to provide a method and a device provided for carrying out the method, with which the removal of objects wound on the bristle roller is simplified.
  • the advantage of the invention is that wound on the bristle roller objects are automatically handled in this way again.
  • a user does not have to pull on the object and does not damage it, for example, by the tensile force which has to be expended against the motor resistance.
  • the attachment is generally very close to the surface of the carpet so there is little room to hand-free the carpet fringes.
  • rotating the bristle roller in the reverse direction provides easier and faster release of the carpet fringes.
  • the motor is preferably a brushless permanent magnet motor. This is advantageous because the commutator motors required commutator are exposed to high wear and it may cause interference. In addition, there is a possibility for sensorless monitoring of the engine, z. B. by detecting the power consumption, so that susceptible to interference sensors such. B. Hall sensors can be dispensed with. The reversal of the direction of rotation can be achieved by using a phase-controlled motor of the bristle roller in a simple manner known per se by swapping two phases.
  • the blockage is detected when a current consumption of the motor exceeds a predetermined or predeterminable limit.
  • a current consumption of the motor exceeds a predetermined or predeterminable limit.
  • the limit value is set to a higher value, which takes into account such surfaces accordingly.
  • the blockage is detected when the current consumption exceeds the limit value for a predetermined or predefinable period of time. This excludes that even a short-term high increase in power consumption, which can be caused by a short "snagging" of the attachment to a surface to be sucked, is evaluated as a blockage and leads to a reverse rotation of the bristle roller. This prevents an inappropriate in this case reverse rotation and the movement of the attachment is not additionally difficult.
  • the bristle roller is rotated in the reverse direction when the blockage occurs by a predetermined or predefinable angle of rotation - angle of return.
  • a predetermined or predefinable angle of rotation - angle of return Values in the range of 15 to 360 degrees have been found to be suitable values for the angle of rotation. Turning back around such a retracting angle may prevent wound-up objects from rewinding when the bristle roller is turned too far in the opposite direction.
  • a low return angle such as 15 degrees, the article may not be fully released, but at least loosened, so that it can then be removed by gentle pulling.
  • the operating direction of rotation can be resumed faster and the cleaning can be continued.
  • the motor of the bristle roller is stopped in the event of a blockage and the bristle roller is rotated step by step by actuating a switching element by a predetermined or predetermined rotational angle in the reverse direction.
  • the return rotation of the bristle roller is thus not automatic, but allows depending on the wound object adapted back turning of the bristle roller.
  • the switching element can be operated by a user who decides how far the bristle roller is to be turned back by operating the switching element as often. The release of longer and / or thin objects, which may wind up several times, is thereby facilitated.
  • a rotational speed of the bristle roller in the reverse direction in a blockage is less than a rotational speed in the operating direction of rotation. This prevents unwrapping objects from being rewound in the opposite direction of rotation.
  • the time to record the normal operation by the user can be selected. This can therefore optionally remove the dissolved objects previously or place the attachment at a different location, so that the objects are not rewound immediately when re-operating the bristle roller.
  • the start button can z. B. be attached directly to the attachment. Simplified, the operation of the bristle roller on the attachment instead by the start button also be resumed by the vacuum cleaner via a main switch first off and then turned on again. In this case, the attachment comes without an additional switch.
  • a signal for resumption of operation in operating direction of rotation is generated by regenerative operation.
  • the generator operation of the motor of the bristle roller takes place by pushing the attachment in a certain direction.
  • the friction generated by contact of the bristle roller with the ground causes rotation of the bristle roller.
  • This rotation generates a voltage from the motor which can be used as a signal to resume operation of the bristle roller in the operating direction of rotation. In this way, the cleaning process can be continued quickly and without additional user manipulations.
  • the operating direction of rotation of the bristle roller is adapted during operation to a forward or backward movement of the attachment and determines the reverse direction of rotation in dependence on the respective operating direction of rotation.
  • the respective operating direction of rotation can be stored in a control unit of the motor of the bristle roller, so that the bristle roller rotates in a blockade in the corresponding opposite direction.
  • a header for a vacuum cleaner with an electrically rotatable bristle roller and a motor for driving, means for detecting a blockage of the bristle roller and for outputting a blocking signal, which may also be referred to as a blockade detection means, provided for reversing the direction of rotation of the motor.
  • a current sensor for measuring a current consumption of the motor of the bristle roller and a monitoring device, which is provided for outputting the blocking signal when the current exceeds a predetermined or predeterminable limit, arranged in the header.
  • Particularly preferred means for monitoring a pending of the blocking signal for more than a predetermined or predetermined time period are provided in the attachment. These can be z. B. from a control unit, which is provided for controlling the motor, includes his. A simple example is a counter which is started by the blocking signal and when expired indicates the lapse of the respective period of time.
  • a button as a switching element for, in particular stepwise, rotating the bristle roller to a predetermined or predetermined angle of rotation in the reverse direction, z. B. on an upper side of the attachment provided.
  • a button can be actuated as often as desired or required to release wound objects.
  • a regenerative startup can take place.
  • the attachment comprises in a preferred embodiment means with which the operating direction of the bristle roller during operation, in particular corresponding to a forward and backward movement of the attachment, is reversible.
  • the movement of such an attachment over a surface can be facilitated by the friction with the surface caused by the rotation of the bristle roller producing a force supporting the movement when the bristle roller rotates in the respective direction of movement. Otherwise, movement of the attachment in one direction and depending on the nature of the surface may be difficult to varying degrees.
  • a header attachment also means, for.
  • Example in a control unit of the attachment, be provided with which an executed before the blockage operating direction of rotation of the bristle roller is stored, and with which then the appropriate for releasing the blockade suitable reverse direction can be activated.
  • FIG. 1 schematically shows a simplified vacuum cleaner 10, which is connected via a suction hose 12 and a suction tube 13 with a header 14.
  • a bristle roller 16 On a lower side of the attachment 14, a bristle roller 16 is arranged, which is electrically rotatable.
  • Such a header 14 is intended primarily for vacuuming carpets.
  • FIG. 2 shows the header 14 now very simplified in a block diagram.
  • the bristle roller 16 is driven by a motor 18.
  • the motor 18 is z.
  • the bristle roller 16 rotates during operation in an operating direction of rotation and thereby objects such. B. garments or components of a carpet, caught in the bristle roller 16 and wound on this, it can lead to a blockage of the brush roller 16.
  • Suitable means for detecting the blockade - blockade detection means 22 - detect the blockage and output a blocking signal 24, here in simplified form as an arrow.
  • the blockage detection means 22 comprise a current sensor 26 and a monitoring device 28.
  • the current sensor 26 detects a current consumption of the motor 18. When the current consumption exceeds a predetermined or predeterminable limit value, wherein the limit value of the engine parameters, for. B. a coil resistance and the motor 18 supplying voltage may be dependent. When the limit value is exceeded, the blocking device 24 outputs the blocking signal 24, for example by the monitoring device 28. To the control unit 20.
  • the control unit 20 comprises means 30 for monitoring a period of time during which the blocking signal 24 is present. When a predetermined or predeterminable time span is exceeded, the state of the bristle roller 16 is recognized as a blockage and the bristle roller 16 is rotated in a reverse direction which is opposite to the operating direction of rotation.
  • the turning back can either be done automatically immediately upon detection of the blockage, wherein the bristle roller 16 by a predetermined or predetermined angle of rotation, the z. B. between 15 and 360 degrees, is turned back.
  • the reverse rotation is done stepwise by pressing a switching element, eg. As a button 32, by a user, after the rotation of the bristle roller 16 has been stopped in the operating direction of rotation when detected blockage.
  • the bristle roller 16 can be rotated back in any number of steps, for example, each 15 degrees.
  • the reverse rotation is optionally performed at a lower rotational speed than the rotation of the bristle roller 16 during normal operation.
