Definitions
- the invention relates to a vacuum cleaner according to the feature of the preamble of claim 1.
- the invention has the object of developing a vacuum cleaner as indicated above so that advantageous flow conditions are given in the support area.
- the support section is curved in cross-section corresponding to a wheel tread or according to a wing profile. With regard to the latter is important that the largest protrusion is only near the edge of the opening.
- the airfoil is thus designed so that during normal forward movement of the vacuum cleaner, the rear part of the profile is forward.
- the bottom plate is formed curved in the direction of displacement both in front of and behind the suction mouth in a cross section corresponding to a wheel tread or a wing profile.
- the base plate having the support sections can be designed both as a metal plate and as a plastic plate. It is essential that a hard material is selected.
- the support section on the suction mouth side merges into a bottom-parallel edge section. The latter is heightwise spaced from the support surfaces of the support sections, so that this edge section does not rest on the floor to be maintained in a sealing manner.
- the support portions according to the invention in cross section by circular sections, in particular composite circular sections of different radii, formed, to which it is proposed that the radius of curvature corresponds to 0.25 to 2 times the Saugmundbreite in the direction of displacement.
- the radius of curvature corresponds to 1/3 to 1/1 times the suction mouth width in the direction of displacement.
- the ratio of the suction mouth width to the radius of curvature of the front support section in the displacement direction is approximately 2: 1 and the rear support section is approximately 1.5: 1.
- a vertical extent of the elevation of the support portion relative to the edge portion corresponds to 1/8 to 1/2 of the radius of the support portion.
- the curvature on the suction mouth edge opposite side of the support section on the Kochhöhungshack is continued with respect to the Saugmundrandes.
- the support section extends at least over the length of the suction mouth measured transversely to the direction of displacement, whereby over this entire length of the suction mouth a uniform sealing of the carpet to achieve a necessary negative pressure is provided.
- the base plate according to the invention does not have a disadvantageous effect with regard to the thread / fiber receptacle, the coarse dirt receptacle and the edge / front extraction in comparison to conventional floor plates. In addition, this is also comparable in terms of acoustics and the appearance of the goods. In the dust collection from cracks / joints an increase has been found.
- FIG. 1 Shown and described is first with reference to Fig. 1 an attachment 1 in the form of a suction nozzle for a vacuum cleaner, not shown.
- This attachment has on its underside a suction mouth 2, in which a suction line not shown in detail opens.
- This suction line is flow-connected to achieve a suction air flow with an arranged in the vacuum cleaner electric motor / fan motor.
- the bottom plate 3 - viewed in the direction of displacement VR - forms 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 Fig. 2 are curved according to a wheel tread.
- the curvatures of the support sections 5 and 6 are directed towards the bottom 4, resulting in a more or less small contact surface depending on the floor covering.
- the device 1 is supported in the region of the suction mouth 2 in carpets with low pile height in cross-section pointwise.
- small bearing surfaces which are smaller in their extension along the direction of rotation VR than the measured in the same direction widths of the respective support section.
- the device 1 is therefore supported only over a partial area of the entire bottom plate in the region of the suction mouth 2.
- the support sections 5 and 6 pass on the suction mouth side in each case into a bottom-parallel edge section 7, which latter is raised above the vertex of the respective support section 5 or 6.
- the vertical extent of this elevation u corresponds in the embodiment shown approximately one-eighth of the radius r 'of the front support section 5.
- the bottom-parallel edge portions 7 extend above the support area on the floor to be maintained 4 and therefore do not interfere.
- the support portions 5 and 6 extend at least over the transverse to the displacement direction VR measured length l of the suction mouth 2.
- the two separate support sections 5 and 6 to form a uniform base plate 3 by means of the suction 2 extending webs 8 are connected.
- the bottom plate 3 according to the invention is preferably made of a metallic material.
- a hard plastic or the like are also conceivable.
- the carpet 4 is well sealed to achieve the necessary negative pressure, which is counteracted by the curved support sections 5, 6 compaction of the carpet 4. This results in an improved flow around (represented by the arrows y), which has a desired increased volume flow in the region of the suction mouth 2 to improve the dust absorption result, without increasing the suction power of the vacuum cleaner.
- the pushing force for moving the device 1 on the floor is reduced by the inventive design, the pushing force for moving the device 1 on the floor to be cared for 4, especially in medium- and high-pile carpets.
