Definitions

  • the handle of the known suction device is as a handling device with all for the suction operation equipped with essential controls. It has an on / off switch for the suction fan of the cylinder vacuum cleaner, Button for adjusting the fan speed, Displays in the form of LEDs and displays as well as an on / off switch for the electric motor drive the brush roll on. Of the brush roller drive associated On / off switch is along with other switches and Display devices arranged on a control panel.
  • the electric motor driven brush roller a textile Damage flooring if e.g. for short-term interruptions the suction of the floor nozzle with rotating Brush roller is turned off.
  • the Drive of the brush roller turns off (US 2 323 554, DE-A 43 43 432).
  • the circuit of the electric motor drive by a Motion sensor has the serious disadvantage that the brush roll itself by an unintentional movement
  • the floor nozzle can suddenly start moving without it this is expected by the user. This results in a considerable risk of injury.
  • an additional safety switch is required, which shuts off the drive of the brush roller as soon as possible the floor nozzle is lifted off the ground.
  • a safety switch is suitable, for example, a bottom-side probe element, that by a vertical adjusting movement the electric motor the brush roller switches (JP-A 4 327 821).
  • Safety switch is also a vacuum sensor can be used, in accordance with the measured negative pressure the Drive the brush roller on and off. At large Negative pressure for operation on a carpet floor is characteristic, the drive is turned on. Becomes the floor nozzle lifted off the ground or on a smooth Underground used, there is a shutdown of Brush roller.
  • the invention is based on the object, the beginning described device so on, that a automatic shutdown of the brush roller drive ensures is, as soon as the suction process is interrupted, and in addition, the risk of injury from the rotating Brush roller is largely eliminated.
  • the object is achieved in that the Functional element upon detection of the handle the drive the brush roller turns on and the brush roller drive switches off again as soon as the handle is released. Once the user interrupts the suction and that at least With a hand-held grip lets go, takes place directly or with a small time delay a shutdown of the brush roller drive.
  • the suction fan the vacuum cleaner can continue to run and is unchanged switchable by a separate on / off switch. A risk of injury through the rotating brush roller is largely eliminated, as by the suction tube, for example as a telescopic tube a length of 500 mm to 1100 mm has, a large distance between the functional element and the brush roller is maintained.
  • the teaching according to the invention allows for surprisingly simple Way a functionally safe shutdown of the rotating Brush roller when the floor nozzle is turned off, and at the same time It effectively protects the user from injury through the rotating brush roller.
  • the inventive Teaching is characterized by the further advantage that they have no additional installation space in the floor nozzle claimed.
  • the functional element can be made of a spring-loaded Operating lever and an operable by the operating lever Button, e.g. designed as a microswitch exist.
  • sensors which respond to a touch of the handle. In Consider, for example, thermal sensors, capacitive Sensors, light sensors and the like.
  • the implementation of the detection signal in a switching operation is also technically feasible in various ways.
  • the simplest solution is that the functional element in one of the vacuum cleaner to the brush roller drive integrated power supply line is.
  • the functional element is useful as a button executed, directly or indirectly via a Operating lever is operable upon detection of the handle and closes the circuit for driving the brush roller as well as the circuit breaks as soon as the handle is released.
  • the Floor nozzle contains an electronic circuit, processes the signals of the functional element and the Drive of the brush roller switches.
  • the signal transmission Can be wired via a cable.
  • Prefers is an embodiment in which the floor nozzle and the functional element Facilities for wireless signal transmission, e.g. by infrared, ultrasound or radio.
  • the energy for the sensors and signal transmission can be provided by a battery arranged in the handle become.
  • driven turbine which is a generator for Power supply of the functional element drives. After all there is the possibility of the handle outside the Handle area with solar cells for the power supply to equip the functional element.
  • the processing of the detection signal is performed by a Electronics in the floor nozzle.
  • the circuit provided for this purpose can contain a timer and trained be that shutdown of the brush roller drive in the absence of a signal with a predetermined time delay takes place.
  • the functional element is with appropriate design of the handle integrated into the handle.
  • the functional element But also as a separate, later on Handle be fastened component.
  • the functional element on the handle attachable housing on which preferably a spring-loaded control lever is held.
  • the housing can a battery compartment and facilities for signal detection and signal transmission included.
  • the invention teaches that the Functional element can be switched off by a separate switch is.
  • switched off the functional element is the Drive the brush roller off and can not in Operation are set. This gives the user the option of to use the floor nozzle without rotating nozzle roller. This is beneficial when sucking sensitive ones Flooring, very high pile carpets and smooth floors.
  • the device shown in Fig. 1 consists in her basic structure of a floor nozzle 1, one to the Floor nozzle 1 connected suction tube 2 and one to a Vacuum cleaner 3 leading hose 4.
  • the floor nozzle 1 has an electromotive brush roller.
  • the suction tube 2 and 4 are the hose through a tubular handle 5 connected.
  • the handle 5 is equipped with a functional element 6, which upon detection of the handle 5 the Drive of the brush roller turns on and the drive again turns off as soon as the handle 5 is released.
  • the Figs. 2 and 3 show a possible embodiment of this functional element 6.
  • the functional element 6 can be fastened to the handle 5, e.g. Clip-on housing 7, on which a spring-loaded control lever 8 is held.
  • the operating lever 8 operates on a trained as a microswitch button 9.
  • the microswitch 9 is arranged on a circuit board 10, the one circuit arrangement for signal processing and wireless signal transmission, e.g. through an infrared transmitter 11, has.
  • the energy for sensors and Signal transmission is provided by batteries 12, which are arranged in a battery compartment of the housing 7.
  • the floor nozzle 1 contains an electronic circuit arrangement, the signals of the functional element. 6 processed and the drive of the brush roller switches.
