Definitions

  • the invention relates to a cleaning device.
  • Cleaning devices include, for example, a support body which is connected to a cleaning sponge.
  • the cleaning sponge consists for example of a PU foam with a constant density and is cuboid. Due to the constant density within the entire cleaning sponge and the cuboid formation, the contact force which is applied by the user by means of the cleaning device to the surface to be cleaned, in the region of the entire cleaning surface of the cleaning sponge substantially the same size. More severe contamination on the surface to be cleaned must be removed by frequent back-and-forth wiping and greatly increased user force on the cleaning sponge.
  • the invention is based on the object to develop a cleaning device of the type mentioned in such a way that partially on the surface to be cleaned, stronger impurities faster and / or by less Force of the user can be easily removed and that the cleaning device is simple and inexpensive to produce.
  • a cleaning device comprising a support body which is connected to a cleaning sponge, wherein the support body on the cleaning sponge side facing at least two stem-shaped projections which are arranged in only one common recess of the cleaning sponge. It is advantageous that the projections facing the surface to be cleaned in each case has a smaller distance from the surface to be cleaned, as the adjoining areas of the support body; In other words, the cleaning sponge has a height between the surface to be cleaned and the projection, which is less than the height of the cleaning sponge in the adjoining the recess regions.
  • the cleaning device If strong contaminants are to be removed from the surface to be cleaned by the cleaning device according to the invention, this is comparatively simple in that the user only has to apply pressure to the surface to be cleaned by means of the supporting body and the cleaning sponge with a slightly increased force. Since the height of the cleaning sponge between the surface to be cleaned and the surface to be cleaned facing front side of the projections is less than the total height of the cleaning sponge, a slightly higher
  • the projections may have a height corresponding to the height of the recess.
  • the cleaning sponge facing end side of the projections is located directly on the bottom of the recess of the cleaning sponge, for example, under low elastic bias.
  • the recess may, viewed in plan view of the cleaning sponge, be substantially square.
  • a good size of the recess for many applications are about 4 x 4 inches.
  • Deviating from the recess, viewed in plan view of the cleaning sponge be rectangular or round.
  • the size of the recess is in each case dimensioned such that the specific surface pressure with which the projections and the cleaning sponge are pressed in this area on the surface to be cleaned, is sufficiently large to easily with normal force and greater pollution from the surface to be cleaned remove.
  • Recesses that have a different shape in plan view, for example, rectangular or round, may also be advantageous for specific applications.
  • the recess may be enclosed by an outer peripheral side surrounding, self-contained edge. It is advantageous that thereby also the projections are circumferentially enclosed by the edge. With surfaces to be cleaned and / or with sensitive baseboards come the Projections during the intended use thereby not directly in contact.
  • the recess can, viewed in longitudinal section of the cleaning sponge, be formed trough-shaped.
  • the production of a trough-shaped recess can be made inexpensively, since production-consuming, but unnecessary for the function unnecessary sharp-edged boundaries of the recess can be avoided.
  • the recess In contrast to the previously described peripherally encircling self-contained edge of the recess, the recess, viewed in cross section of the cleaning sponge, be open on the longitudinal sides of the cleaning sponge. As a result, the production is further simplified.
  • a sponge-like, plate-shaped semi-finished product can be processed by a milling or planing tool such that it subsequently has a recess over the entire length, which are open in the machine direction.
  • the semifinished product is assembled. This happens because ready-to-use cleaning sponges are cut out of the semifinished product; For example, the semi-finished product is cut transversely to the machining direction, so that a ready-to-use cleaning sponge is produced. For most applications, there is no disadvantage if the recess in the region of the longitudinal sides of the cleaning sponge are open; However, the production is considerably simplified by such a configuration and significantly cheaper.
  • the ratio of the length of the cleaning sponge to the length of the recess is preferably 3: 1.
  • the ratio is advantageous. If the ratio were smaller, the cleaning surface of the cleaning sponge under the recess would be too large relative to the entire cleaning surface of the cleaning sponge and the user could exercise with normal force only insufficient contact pressure on the surface to be cleaned. On the other hand, if the ratio were greater, it would often have to be wiped back and forth to clean heavily soiled areas by the small cleaning area in the area of the recess, which would be detrimental in terms of good cleaning efficiency of the area to be cleaned.
  • the cleaning sponge and the recess are preferably symmetrical to an imaginary, the cleaning sponge formed in half-length transversely cutting through plane.
  • the symmetry promotes easy handling of the cleaning device since the user characteristics of the cleaning device are well predictable by the user due to its symmetry.
  • the ratio of the height of the recess to the height of the cleaning sponge is preferably 0.3 to 0.95.
  • Cleaning sponge and the front side of the projections is only very small. Although it is advantageous that thereby the force of the user can be applied almost immediately and without loss to the surface to be cleaned, it is disadvantageous, however, that the cleaning sponge is exposed to a high mechanical load in the region of its very low height, thereby relatively quickly wears and in the event of damage to the cleaning sponge in the region of the projections there is a risk of damaging the surface to be cleaned.
  • the cleaning sponge has a cleaning cloth on the side facing the surface to be cleaned, preferably made of microfiber, wherein the projections then act on pressure on the cleaning sponge directly on the cleaning cloth.
  • the ratio of the height of the recess to the height of the cleaning sponge is 0.5 to 0.75. In such an embodiment, a very good compromise between the increased cleaning performance in the region of the projections on the one hand and the durability of the cleaning sponge in this area on the other hand given.
  • the recess is arranged only in a partial region of the cleaning sponge and the subregion forms a power zone with enhanced cleaning performance, based on the regions of the cleaning sponge adjoining the partial region. It is advantageous that the force of the user on the, relative to the entire cleaning surface, smaller
