Definitions

  • the invention relates to a vacuum cleaner with a dirt collecting container and an attachable to the dirt collecting suction head having at least one suction unit is connected via a suction inlet with the dirt collecting in flow connection, wherein at the suction inlet a dipping into the dirt collecting filter cage is arranged on which a filter element detachably fixable is.

  • the dirt collecting container has a suction connection, to which a suction hose can be connected, which carries a nozzle at the free end for sucking off the surface. From the at least one suction unit, a suction flow is generated so that suction air laden with dirt particles can be sucked into the dirt collecting container via the suction hose.
  • the suction air flows through a filter element, which is detachably fixable to a filter cage, which is arranged at the suction inlet.
  • the filtered suction air then flows to the at least one suction unit and is discharged from the latter via at least one suction outlet, which is arranged on the suction head, to the environment.
  • the vacuum cleaner is designed as a wet-dry vacuum cleaner, so that not only dry suction air is sucked in. but it can also be sucked a liquid from a surface and transferred to the dirt collector.
  • the suction head can be removed from the dirt collector.
  • the user vertically aligned the suction head removed from the dirt collecting container, d. H. with the filter cage projecting downwards on the floor surface. This involves the risk that the suction head then falls over and is damaged because the filter cage only allows a very unstable position of the suction head.
  • the user should instead tilt the suction head and place it on the floor surface on the long side.
  • Object of the present invention is therefore to develop a vacuum cleaner of the generic type such that the risk is reduced that the user turns off the suction head for emptying the dirt collection container vertically aligned on a floor surface.
  • this object is achieved according to the invention in that a support element projects radially from the underside of the filter cage, offset from the center axis thereof. If the user tries to lift the suction head in a vertical orientation, ie pointing downwards Filter cage to park on a floor surface, so contacted first, the support element, the bottom surface. This is arranged radially offset from the central axis of the filter cage. As a result, a tilting moment acts on the suction head and it is therefore not possible for the user to turn off the suction head in a vertically aligned manner. Rather, the user is forced to tilt the suction head and place it longitudinally on the floor surface.

  • the filter cage is preferably cylindrical. In this case, the center axis of the filter cage coincides with its cylinder axis.

  • the support element occupies a position within the winch area covered by the baffle wall. If the user attempts to stop the suction head on the support element, then the weight of the suction head exerts a tilting element in the direction away from the baffle, so that the user will readily deposit the suction head on the side facing away from the baffle on the bottom surface. Damage to the baffle when placing the suction head is thereby prevented in a structurally simple manner.

Abstract

L'invention concerne un aspirateur (10) comportant un réservoir à poussière (11) sur lequel est placée une tête d'aspiration (13) qui comprend au moins un organe d'aspiration en communication fluide avec le réservoir à poussière par l'intermédiaire d'une entrée d'aspiration (30). Dans l'entrée d'aspiration est disposée une cage filtrante (36) qui pénètre dans le réservoir à poussière et sur laquelle un élément filtrant (62) est fixé libérable. L'invention vise à perfectionner l'aspirateur (10) afin d'éviter qu'un utilisateur ne pose la tête d'aspiration à la verticale sur le sol pour vider le réservoir à poussière. A cet effet, un élément d'appui (54) est disposé en saillie relativement à la face inférieure de la cage filtrante et en décalage radial par rapport à son axe médian (52).
