Definitions

  • the invention relates to a vacuum cleaner with a Electric motor and one ending in a suction mouth Suction line, the suction mouth on the underside by a Bottom plate is limited and further the bottom plate Has support sections.
  • the inventive design of the base plate is an at least constant pushing force increased dust absorption.
  • the support section is in cross section corresponding to a wheel tread or curved according to a wing profile. Regarding the latter is significant that the largest protrusion is only near the edge of the opening.
  • the wing profile is so designed that it is common Forward movement of the rear vacuum cleaner Parts of the profile is in front.
  • a support section is formed in front of and behind the suction mouth is, it is provided that both support sections are the same.
  • the base plate is in Direction of movement both in front of and behind the suction mouth in a cross section corresponding to a wheel tread or a wing profile curved.
  • Such a, evenly curved, support sections having base plate can be used as metal or be designed as a plastic plate. Essential here is that a hard material is chosen.
  • the support sections are different are designed.
  • the support section arranged at the front in the direction of displacement has a smaller radius of curvature than the rear support section in the direction of displacement. It is also proposed that the support section on the suction mouth side into a floor section parallel to the floor transforms. The latter is the height of the contact surfaces the support sections spaced so that this Edge section not sealing on the part to be maintained Ground. This affects this parallel to the floor Edge section not negative for the flow of the Carpet or on the pushing forces. Corresponding a wheel tread or a wing profile are the support sections according to the invention in cross section through circular sections, in particular compound Circular sections of different radii, formed, for which it is proposed that the radius of curvature the 0.25 to 2 times the suction mouth width in the direction of displacement corresponds.
  • an embodiment is preferred here, at which the radius of curvature is 1/3 to 1/1 times the suction mouth width in the direction of displacement corresponds.
  • the ratio is from suction mouth width to the radius of curvature in the direction of displacement front support section about 2: 1 and rear support section about 1.5: 1.
  • a vertical measure of the elevation of the support section compared to the edge section 1/8 to 1/2 of Radius of the support section corresponds.
  • the curvature on the Suction mouth edge opposite side of the support section about the amount of cant with respect to the suction mouth edge is continued.
  • the bottom plate according to the invention has an effect the thread / fiber pick-up, the coarse dirt pick-up and edge / front suction compared to conventional Bottom plates not disadvantageous. Beyond that this also with regard to acoustics and the appearance of the goods comparable. When picking up dust from cracks / joints an increase has been identified.
  • This attachment has a suction mouth 2 on the underside in which a suction line, not shown flows.
  • This suction line is for achieving a suction air flow with an electric motor / blower motor arranged in the vacuum cleaner fluidly connected.
  • the base plate 3 - in the direction of displacement VR considered - a front support section 5 and a rear support section 6, which support sections 5, 6 in a cross section in the direction of displacement VR according to FIG. 2 corresponding to a wheel tread are curved.
  • Support sections 5 and 6 have different Radii, the radius r 'of the front support section 5 approximately - measured in the direction of displacement VR - corresponds to half the suction mouth width b.
  • the radius r '' of the rear support section 6 corresponds in that shown embodiment about 0.7 times the Suction mouth width b.
  • the curvatures of the support sections 5 and 6 are in Direction directed to the floor 4, whereby each a more or less small contact surface after the floor covering results. So the device 1 is supported in the area of the suction mouth 2 for carpets with a low pile height in points from the cross section. With carpets with medium to large pile height according to FIG. 2 result small contact surfaces, which in their extension along the direction of displacement VR are smaller than that in widths of the respective direction measured in the same direction Support section. The device 1 is therefore based only over part of the entire floor slab in the Area of the suction mouth 2.
  • the support sections 5 and 6 go on the suction mouth side in each case into an edge section 7 parallel to the floor, which is the latter relative to the vertex of each Support section 5 or 6 is inflated.
  • the vertical The measure of this increase u corresponds to that shown Embodiment approximately one eighth of the radius r ' of the front support section 5.
  • the curvatures of the respective support section 5, 6 are on the opposite side of the suction mouth edge 7 the support section 5, 6 about the cant u continued with respect to the suction mouth edge 7, so that both in the VR direction of movement and counter to this each result in soft run-up zones Z.
  • the base plate 3 according to the invention is preferred made of a metallic material. However, there are also Configurations made of a hard plastic or the like conceivable.
