Definitions

  • the invention relates to a hand-held cleaning device, comprising a housing which has an electric drive motor for two roller-shaped cleaning bodies, for example, which are mounted in the housing and can be driven via a reduction and provided with a cover.
  • a cleaning device of the type mentioned is described, for example, in US Pat. No. 2,941,252.
  • This is used for cleaning blinds and has a housing in which a drive motor is mounted, which drives two parallel roller brushes lying parallel to one another via several bevel gear pairs, which are supported at both ends on a housing part designed as a cover.
  • the direction of rotation of the cleaning brushes is directed in the opposite direction so that the dirt is brushed outwards onto the cover.
  • a handle designed as a dust extraction tube is provided, to which a vacuum cleaner is to be connected.
  • the majority of the devices known to date provide for the device to be connected to the suction pipe of a conventional vacuum cleaner.
  • a cumbersome handling and preparation for putting the device into operation is the result and should be mentioned as a further cachet.
  • the invention has for its object to provide a cleaning device of the type mentioned above so that simple and easy handling is ensured and effective dust extraction can be achieved even with low drive power.
  • the two cleaning bodies are partially provided with a cover which fits into a housing provided in the housing traction channel that opens with the suction side of a blower. and a dust collector is connected.
  • the dust or dirt from the object to be cleaned is therefore brushed inwards directly into the exhaust duct, which means that satisfactory dust extraction can also be achieved with a low blower output.
  • the size and weight of the device can thus be kept small, a cumbersome connection to a vacuum cleaner is no longer necessary.
  • the cover partially surrounding the cleaning body is connected to the housing and a suction nozzle or the like is provided for dust extraction, which can be attached instead of or to the cover. Since the cleaning device can therefore also be used as a vacuum cleaner for many purposes, it is advantageous if, according to a further embodiment of the invention, a single drive motor is used to drive the cleaning bodies and the blower and a reduction gear is provided between the driving motor and the cleaning body.
  • the reduction gear is designed as a worm gear or as a double spur gear. It is thus possible to provide both the cleaning body and the fan impeller with the optimum working speed for them, and advantageously achieves a brush arrangement protruding from the lower edge of the device, even with a smaller brush diameter. This enables the use of a high-speed brush Drive motor, a further reduction in weight and size of the device can be achieved.
  • the reduced drive shafts are designed as hollow shafts, into which the cleaning bodies fastened on an axis can be inserted in a driving manner. This ensures a space-saving storage of the cleaning bodies integrated with the reduction gear, which also makes it possible to arrange them on the fly and easily replaceable.
  • a further development of the invention can also provide an overload protection, preferably a mechanical slip clutch that can be attached after the reduction gear.
  • a further development of an embodiment of the invention which is advantageous for many applications is that the reduction gear for the cleaning bodies and / or the fan rotor can be connected to the shaft of the drive motor via a releasable coupling.
  • This is for the unnecessary cleaning body, e.g. B. when suctioning objects, even unnecessary gear not in Funkti on, which not only reduces the noise of the cleaning body, but also the power consumption.
  • Switching off the fan rotor is particularly advantageous, for example, when polishing objects, since in this case suction is not required.
  • a particularly advantageous development of the invention is achieved when the axes of the drive motor and the cleaning body are perpendicular to each other and that the fan rotor connected to the shaft of the drive motor is mounted in the flow direction behind the opening of the cover in the housing and between the drive motor and the reduction gear and the dust collection container is arranged at the end of a subsequent dust extraction duct, which is preferably designed as a handle. It is thus a cleaning device with an effective suction and brushing performance, which has small dimensions and a low weight, also ensures good accessibility. Furthermore, there is the possibility of designing the size of the dust collecting container depending on the application, for example as a shoe cleaning device, in the handle and when used for cleaning upholstered furniture or the like, to be laid outside in the form of a sack.
  • a particularly useful and just as handy and with good ventilation version of a cleaning device is made possible by a further embodiment of the invention in that the axes of the drive motor and the cleaning body are aligned and that the fan rotor connected to the shaft of the drive motor on the opposite of the reduction gear Side is stored and the dust collector is arranged in front of the fan rotor. The dust is sucked into the dust collector via a handle designed as an extractor tube, and the air cleaned in it is directed outside via ventilation slots on the housing.
  • a particularly good handling and a balanced weight distribution of the device is given if, according to a further development according to the invention, it is provided that the axes of the drive motor and the cleaning body are aligned and that the fan rotor connected to the shaft of the drive motor is in the flow direction behind the mouth of the cover is mounted in the housing, to which the reduction gear connects in the direction of the drive motor, the dust-collecting container being arranged at the end of a discharge tube designed as a handle.
  • the axes of the drive motor and the cleaner ungsharm are perpendicular to each other and that the blower rotor connected to the drive motor is arranged on the opposite side of the reduction gear, in front of which the dust collector is located.
  • the intake air flows through the engine compartment, which ensures good cooling of the drive motor.
  • a fixed support body preferably pivotable about its axis or a lowerable support body, e.g. for supporting a Venetian blind slat to be cleaned, can be inserted into the housing, which extends at least over part of the length of the working surface of the cleaning body Be adapted to the curvature of the blind slat.
