Definitions

  • the invention relates to a vacuum cleaner with a nozzle housing part, which is reciprocated on the surface to be cleaned by means of a first rolling device, and with respect to this at an angle to the vertical variably tiltable motor housing part in which or on which a dust-collecting device is housed, and with an arranged on the motor housing part hand guide means for the vacuum cleaner, for tilting the motor housing part relative to the nozzle housing part and for reciprocating the vacuum cleaner, wherein leads away from the motor housing part of a flexible suction hose, at the other end a permeable handle part is provided with a rigid suction tube which opens out in a suction opening, wherein the handle part with the suction pipe so on or in the motor housing part detachably can be arranged that it also forms the hand guide means for the vacuum cleaner, and wherein the handle part with the suction pipe from the motor housing part is removable and manually guided for sucking directly over the suction port of the suction pipe is used.
  • EP 1 265 519 B1 DE 601 12 258 T2
  • the suction tube In order to use the handle part with the suction tube as a hand guide means of the vacuum cleaner, the suction tube must be inserted telescopically into the tube and arranged with this on the motor housing part.
  • a switchover of a valve takes place via an unspecified device such that it is no longer the suction hose, but the nozzle housing part which can be unrolled on the surface to be cleaned, which is subjected to negative pressure.
  • the handle part is released with the suction pipe from the motor housing part, so again switching the valve occurs.
  • the telescopic arrangement of the suction hose and the rigid suction tube has the further disadvantage that complex Umstecktex are required if the handle part between the suction hose and suction tube to be positioned, but which is regularly required to reach remote from the user areas, for example, on the ceiling can.
  • the present invention has for its object to improve a vacuum cleaner of the type described above in such a way that it is easier to handle and design is simpler and thus less expensive to produce.
  • suction hose and the handle part with the suction pipe during operation of the vacuum cleaner constantly subjected to negative pressure and are flowed through, and that acted upon by vacuum and air flowed handle part with the suction - when he am or is arranged in the motor housing part - communicates with the nozzle housing part and generates a suction air flow through the nozzle housing part.
  • the vacuum cleaner according to the invention can be dispensed with a complex and otherwise fault-prone switching device for the negative pressure of the nozzle housing part on the one hand and the suction hose on the other hand.
  • no further conversion or Umsteck′ are required when removing the handle part and the suction pipe from the motor housing part.
  • the suction tube communicates with its remote from the handle portion and the suction hose suction opening with the nozzle housing part.
  • the suction pipe is therefore even attached in or on the motor housing part; it is not, as in the aforementioned prior art, introduced telescopically in the suction hose, which would be cumbersome and also would allow no further functional usability of the suction tube.
  • a flexible flow-through coupling device is provided between the suction opening of the suction pipe and the nozzle housing part, which is adapted to permit flow communication between the nozzle housing part and suction pipe even when tilting the motor housing part to the nozzle housing part.
  • the coupling device forms a flow channel between the suction pipe and the nozzle housing part.
  • the coupling device may be designed such that it supports the suction pipe when it is arranged on or in the motor housing part.
  • the coupling device comprises a pivotable joint arrangement with a receptacle, with which the suction tube, in particular pluggable is connectable.
  • the coupling device is rotatably supported in the nozzle housing part, wherein the axis about which the hinge assembly is pivotable, and the axis about which the motor housing part is pivotable, are arranged parallel to each other.
  • the suction tube can be plugged onto the receptacle of the coupling device or can be inserted in it.
  • Receiving and suction tube can be, for example, by an additional, in particular elastomeric sealant, the in the receptacle is arranged to be leak-tight connected to each other.
  • the motor housing part on its side facing the user on an elongated open-edged recess in which the suction tube is detachably arranged, wherein means are provided for releasably fixing the suction tube in the recess.
  • the recess preferably extends substantially over the entire side of the motor housing part facing the user.
  • the means for releasably fixing the suction tube in the recess are basically arbitrary and include, for example, means by which the suction tube can be clipped to the motor housing part, hooked or latched.
  • the elongated open-edged recess itself forms the means for releasably fixing the suction tube, for example, characterized in that the width of the open-edged portion of the recess is smaller than the diameter of the suction tube, whereby it held against falling transversely to the axis of the recess is.
  • the recess viewed in cross-section, per se have any shape, wherein the vacuum cleaner can be made particularly compact, when the recess is formed complementary to the shape of the suction tube. It proves to be advantageous from a manufacturing point of view if the cutout viewed in cross-section is essentially arcuate or box-like.
  • the motor housing part an additional second rolling device is provided, such that the motor housing part, preferably together with the Nozzle housing part, about a horizontal tilting axis on the surface is tilted and rests with the additional rolling device on this surface and against this surface unrollable and can be pulled by means of the suction hose.
  • the vacuum cleaner both as a so-called “upright” vacuum cleaner, in which the motor housing part is pivoted substantially opposite the nozzle housing part upwards, as well as a so-called “sled” -sucker, in which the motor housing part substantially parallel is arranged to be machined surface, can be used.
  • An embodiment of the motor housing part is preferred in which the suction hose opens out of the side of the motor housing part which is opposite the second rolling device. As a result, the suction hose does not hinder the carriage operation of the vacuum cleaner.
  • the first rolling device serves both for unrolling the nozzle housing part relative to the surface to be cleaned and for unrolling the vacuum cleaner in the tilted state.
  • the suction pipe has a removable nozzle on the end facing away from the handle part.
  • the detachable nozzle has a roller device in order to be moved in a rolling motion relative to a surface to be cleaned. As a result, the user-friendliness of the vacuum cleaner is further improved.
  • the handle part has a first opening for connecting the handle part to the suction tube and a second opening for connecting the handle part with the suction hose.
  • the openings form an acute angle to each other. This proves to be advantageous and practical in handling.
  • an electrically driven brush device is provided in the nozzle housing part.
  • an automatic shutdown of the brush device when removing the suction tube from the motor housing part and an automatic switching on the brush device when reintroducing the suction tube on the motor housing part are provided.
