Definitions

  • the invention relates to a suction nozzle consisting of a nozzle body enclosing a suction chamber and provided with a connecting suction nozzle, the open side of which is closed with a fixed or replaceable attachment plate made of metal or plastic and having a suction opening.
  • Suction nozzles for cleaning surfaces are known and widely used as vacuum cleaner nozzles with and without attachment plate to be attached to the nozzle body.
  • Nozzles with brush bristles, bristle material or felt are used to clean carpets and smooth surfaces.
  • the suction effect of the vacuum cleaner itself also plays a major role.
  • attachment plates attached to the nozzle body worsen the suction effect.
  • the nozzles adhere and tend to suck onto the surface to be cleaned, with a mechanical effect being added to the air effect caused by the suction.
  • the disadvantages of the known vacuum cleaner nozzles therefore consist, on the one hand, of a relatively high energy requirement required by the hammered suction effect and, on the other hand, of the force to be used to actuate the vacuum cleaner.
  • nozzle designs are required for carpets and smooth surfaces to be cleaned.
  • high-pile carpets for example, specially designed nozzles with individual cylindrical suction tubes have been developed. Apart from the fact that such nozzles are only suitable for high pile carpets, they also have the deficiencies mentioned.
  • Other known metal plates for vacuum cleaner nozzles with brush trimmings have, on their outer side, longitudinal elevations which create air channels for cross flows. However, these nozzles also do not work optimally, since the numerous cross currents encountered by the edge suction partially inhibit one another and thereby impair the perfect suction.
  • a suction nozzle of the type mentioned at the outset is shown, for example, in FR-A 2 554 340.
  • the object of the invention is to provide a suction nozzle of the type mentioned, which can be used for all surfaces to be cleaned without special accessories and which can achieve a better cleaning effect than with the known vacuum cleaner nozzles with less energy and less effort.
  • Such a suction nozzle is particularly suitable for vacuum cleaners and in such a vacuum cleaner nozzle the full suction power of the vacuum cleaner and thus the energy used is optimally used.
  • the air supply channels opening tangentially into the chambers create rotational currents and a cross flow, this cross flow flowing in one direction over the surface to be cleaned. This ensures that the dirt particles get into the suction chamber in a practically aligned manner and are suctioned off.
  • the cross currents of the attachment plate of the vacuum cleaner nozzle designed according to the invention are subdivided into eddy currents, the sum of which result in a single cross flow which consists of eddy currents arranged in a row.
  • the support plate is relatively large and the air supply channels always remain open. Sucking the front panel into the pile of a carpet and thus partially closing the air supply or suction channels, which ultimately results in the high pushing force required in conventional vacuum cleaners, does not occur.
  • the front plate made of metal or plastic with the smooth outer surface and the high working line can also be used to extract water and, for example, to clean swimming pools. In addition to the excellent work that is achieved by an attachment plate according to the invention, this also offers manufacturing advantages, since it can be manufactured from a single piece according to a template.
  • the vacuum cleaner nozzle (Fig. 1) consists in a conventional manner of a nozzle body D with connection suction port S.
  • an attachment plate 1 made of metal or plastic is arranged on the open side of the nozzle body D.
  • twelve circular chambers 2 to 13 are out. saves, of which the middle, the suction nozzle S opposite chambers 6, 7, 8 and 9 to the suction chamber of the nozzle body D are open.
  • the outer chambers 2, 3, 4 and 11, 12, 13 are closed by a floor opposite the suction chamber.
  • These chambers 5 and 10 are therefore only open in their central region with respect to the suction chamber, while the other chambers 6 to 9 forming the suction opening are completely open.
  • an air supply duct 15, 15 opens out tangentially. 16, 16 ', 16a, 16a'.
  • the air supply channels 15, 15a and 16, 16 ', 16a, 16a' each start from a longitudinal edge 17 or 18 of the facing plate 1 and run obliquely until they open tangentially into the chambers 2 to 13 assigned to them.
  • a series of such air supply ducts is accordingly provided on each side of the chambers 2 to 13.
  • the air supply channels 15, one (first) row and the air supply channels 16, 16 'of the other (second) row on one side of a transverse line BB intersecting the suction opening 14 are essentially mirror images of the air supply channels 15a and 16a, 16a' on the other Side of this cross line BB are arranged.
  • the air supply channels are arranged as follows.
  • three air supply channels 15 are provided on one side of the transverse line B-B, one air supply channel starting from the corner E1 and the other two air supply channels 15 starting from the longitudinal edge 17 of the facing plate 1.
  • three air supply channels 15a are also arranged on the other side of the transverse line B-B, an air supply channel also starting from the corner Ea of the front plate 1.
  • the air supply ducts 15 open into the chambers 3, 5 and 7, that is to say into every second chamber.
  • the air supply channels 15a open into the chambers 8, 10 and 12. From this arrangement it follows that in the first row the air supply channels 15, 15a lead into adjacent chambers 7 and 8 in the middle of the facing plate 1.
  • the air supply channels 16, 16a are arranged somewhat differently.
  • Four air supply ducts 16 'and 16 are provided on one side of the cross line B-B, which are opposed by three air supply ducts 16a and 16a' on the other side of the cross line B-B.
  • the air supply channel 16 'opening into the chamber 2 starts from the corner E2 of the front plate 1 and corresponds to the air supply channel 16a' at the opposite corner E2a of the front plate 1, which opens into the outermost chamber 13.
  • the two air supply channels 16a opening into the chambers 9 and 11 are a mirror image of the air supply channels 16 which open into the chambers 6 and 8.
  • a brush trim consists of strips 20 made of inclined bristle material.
  • the depth of the chambers 2 to 13 in relation to the depth of the air supply channels 15, 15a, 16, 16 ', 16a and 16a' is expediently coordinated with one another, the chambers being approximately twice as deep as the air supply channels.
  • the attachment plate can be firmly connected to a nozzle body, but it can also be detachable and thus interchangeable like other attachment plates or additional brushes. There are numerous devices for this, which allow the plate to latch onto the nozzle body.
