Definitions

  • the invention relates to an electric vacuum cleaner with a base unit and a header, wherein between the base unit and the attachment a hinged connection is provided for the pivotal movement of the base unit transversely to a conventional travel direction between a parking position in which the vacuum cleaner is automatically by means of the attachment , and a working position, in which due to the movement results in a changing angular orientation between the base unit and the attachment, wherein the parking position is secured by a surmountable solely by manual power lock.
  • Electric vacuum cleaner of the type in question are known in which the trained for floor cleaning attachment is connected, for example in the form of a suction nozzle on a simultaneously forming the suction line to the base unit tilting joint connection to the suction flow performing basic unit.
  • the basic unit In the course of the usual working movement in and contrary to the usual direction of travel, different angles between the attachment and the basic unit.
  • a safety lock of the basic unit is achieved to the attachment, for example in the parking position, which is realized using the magnetic force in a structurally simple manner.
  • the proposed solution is further reduced compared to the solutions of the prior art. Only two parts are needed for the proposed barrier, such as a magnet and an opposite. These required for the magnetic attachment parts can be further positioned in a hidden position behind the usual plastic panel of the basic unit and attachment or connecting these devices joint training. The force of the magnetic connection is in this case further selected so that a self-retaining lock in the parking position, in which the magnetic arrest reaching parts are in superposition, is achieved.
  • this latching is further given by magnetic attachment even if, for example, the entire vacuum cleaner is tilted in the park-angle position of the basic unit and attachment to each other, for example, for transport.
  • the Magnetverhaftung is only deliberately by manual force by displacement of a magnetic part of the other away repealed.
  • a permanent magnet is arranged in the base unit or the attachment and in the other device a ferromagnetic opposite.
  • magnets interacting with one another are fixed in both devices, for example in pockets, slots, holes, etc.
  • the magnetic surfaces may be covered or coated for protection.
  • the magnet is arranged outside the axis of rotation of the articulated connection. As the distance to the axis of rotation of the articulated connection increases, the lever arm between the magnet and the pivot increases correspondingly, which has a further advantageous effect on the operation of the device.
  • an electronic device for detecting and evaluating the respective joint position, in particular the parking position, an electronic device may be provided in an embodiment of the invention, which optionally switches off the suction fan of the vacuum cleaner depending on the detection of a parking position or at least down regulated and further optionally one example in the Front attachment provided electric motor driven tillage brush shuts off in this parking position, so as to avoid damage to the soil at standstill of the vacuum cleaner in the park position.
  • the magnet acts in at least one of the pivot positions on a reed contact, so in particular in the parking position, in which then located in close proximity magnet closes the reed contact. It is therefore achieved a contactless, wear-susceptible detection of the joint position.
  • the arrangement of the aforementioned electronics for evaluating the reed contact signal and for controlling the corresponding functions of the vacuum cleaner can be positioned as such according to the proposed solution without wiring the hinge joint as such in the header alone.
  • FIG. 1 Shown and described is first with reference to Fig. 1 an electric vacuum cleaner S in the form of a hand vacuum cleaner with a stalk-guided basic unit 1 via which by means of a Kippgelenk tone 2 a header 3 in the form of a floor nozzle fluidly and optionally electrically connected, wherein a Kippgelenkachse x parallel to a transverse to the usual direction of travel r aligned end face. 4 of the attachment 3.
  • the tilting joint initially consists essentially of a fixed in the header 3 input channel section 5 and to the latter about the axis x tiltable, connectable to the vacuum cleaner 1 output channel section. 6
  • the associated ends 7, 8 of the input channel section 5 and the output channel section 6 have circular segment-shaped sections which each correspond to approximately a quarter circle section, wherein further the outer contour of the end 7 of the input channel section 5 of the corresponding inner contour of the administratchanalabintroductoryendes 8 is adjusted, so that the end 7 in the end 8 of the output channel section 6 can dip.
  • a telescoping of the channel sections 5, 6 is given in the region of their ends 7, 8, which is further achieved in that the circular segment-shaped ends 7 and 8 are arranged concentrically on the tilting axis x, which latter by the circular segment-shaped formation of the ends 7, the eighth is outside the suction channel.
  • a permanent magnet 11 inserted in the region of the output channel section 6 in the region of the output channel section 6 in the region of the output channel section 6 is the front side, d. H. facing the end face 4 of the attachment 3 in the jacket wall, a permanent magnet 11 inserted.
  • this magnet 11 is assigned to the base unit 1 via the connecting piece 10.
  • a ferromagnetic opposite 12 is positioned in extension of the pivoting path of the output channel side magnet 11, this in the illustrated embodiment in hidden position behind the housing trim 13 facing the output duct section 6.
  • the in Fig. 2 Park position shown is preferably a tilt angle of the base unit 1 to the footprint of over 90 °, ie a vertical V reachable.
  • the outlet channel section 6 tilts beyond the vertical V into a position in which the connection nozzle axis x has been displaced over the vertical V by an angle alpha of approximately 4 °.
  • the magnet 11 receiving wall of the output channel section 6 leans on the associated housing 13 of the attachment 3 from under cover of magnet 11 and opposite 12, according to which a magnetic attachment to form a barrier 20 of this parking position is reached.
  • This magnet-arrested parking position can be further detected by a schematically illustrated reed contact 14 whose signal is evaluated by a control unit 15 shown schematically.
  • the suction fan of the base unit 1 is down-regulated in terms of speed or possibly switched off.
  • the magnetically arrested parking position as shown in FIG Fig. 2 is only intentionally, however, can be canceled only by manual force, in which, for example, by holding down the attachment 3, the base unit 1 about the pivot axis x back to the working position as shown in FIG Fig. 3 is shifted, wherein the output channel side magnet 11 is removed from the ferromagnetic opposite 12.
  • the in Fig. 3 Partly shown in phantom shown working position, in which due to the movement of the vacuum cleaner S a changing angular orientation between the base unit 1 and the attachment 3 is achieved, a sufficient distance of the magnet 11 to the opposite 12 is always preserved, so that in the working position no magnetic attachment and In addition, no signal triggering via the reed contact 14 is achieved.
  • the base-side magnet 11 may be integrally formed on an outer side of the output channel section 6, protruding substantially radially with respect to the tilting axis x into the front attachment 3 Boom 16 to be mounted end, for cooperation with a correspondingly opposite position, which is defined in the attachment 3 in the region of a housing portion 13.
  • This solution can also be provided with a reed contact for signal control of an electronic system.
  • the magnet detained parking position is maintained even with a lifting of the entire vacuum cleaner S in this position.
