Definitions

  • the invention relates to a Upright-type vacuum cleaner with an upper body with dust collection container, with a bottom unit, which is movable by a chassis on the surface to be cleaned, the upper body is at least pivotally mounted relative to the ground unit and can be locked in a parking position, in the the vacuum cleaner occupies a substantially vertical position on the surface to be cleaned, with an engine fan for producing a negative pressure acting on the surface to be cleaned, and with an air duct extending from the bottom unit into the dust collector, which has an interface and fluidly behind Interface comprises a trained as a hose or hose-tube combination component, which is laid outside the upper body on this halterbar and after a separation in the interface allows independent of the ground unit suction operation.
  • the following describes three types of vacuum cleaner that differ in their construction and operation. As common features all have a motor-driven blower, a dust collection room and one or more adapted to the particular purpose tillage equipment.
  • the vacuum cleaner has a housing which is movable on rollers and / or skids on the ground to be processed.
  • the engine fan and the dust collector are arranged in the housing.
  • the soil treatment device - here called floor nozzle - is connected via a suction hose, possibly with an intermediate suction pipe with the dust collection chamber.
  • the housing is brought into the desired position during the suction process by pulling on the suction tube.
  • the motor fan and the dust collector are also arranged in a housing. From the housing extends on one side of a suction pipe, which connects a floor nozzle with the dust collector, and on the other hand, a handle with which the housing is maneuvered into the desired position.
  • An essential feature of an upright is a movable floor unit, which carries a torso with a large dust collector.
  • the two parts are pivotally mounted to each other and usually fixable in a parking position in which the upper body is approximately vertical when the ground unit is in the use position on a horizontal ground. In this position, the upright is automatic.
  • this lock is released and the upper body tilted by a certain angle in a working position. The swivel angle depends on the one hand on the size of the user and on the other hand from the respective use.
  • a handle on the upper body is used to guide the entire device.
  • the air duct has an interface and fluid behind the interface designed as a hose or hose-tube combination component.
  • a piece of pipe is held in a plug-in receptacle in most cases.
  • different suction attachments can be placed on the suction end and the resulting arrangement can be used as in a conventional vacuum cleaner.
  • a relatively long hose is used, see recordable WO 2007/008770 A1 , These are then held in clamps or hooks on the handle. This creates above the upper body loops, with which the user can hang on moving around on various objects.
  • the invention thus raises the problem of disclosing a vacuum cleaner of the type mentioned above with a secure and ergonomically advantageous holder of the hose.
  • the tube is halterbar in an elongated, approximately U-shaped receptacle, which is embedded in at least one side surface and at least a portion of the top.
  • the replacement of the hose is supported by the fact that it moves automatically in the parking position of the vacuum cleaner by supporting gravity in the direction of the recording and remains there.
  • the U-shaped receptacle extends over almost the entire length of the tube in the retained state, wherein only the transition region of the tube is recessed in the upper body.
  • the receptacle in the transition region has a quarter-circle-shaped cross-section.
  • the transition region can be pivoted on the upper body mounted bow, which in turn increases the stability of the upright when the hose is pulled backwards.
  • the transition region consists of the bow and a piece of hose encased by a bend protection.
  • the hose is designed as a flexible hose that can be stretched in length. This increases the range.
  • suction adapters can be placed on the end of the hose or pipe section adjacent to the interface, which can then be held on the rear wall of the upper body.
