Definitions

  • the present invention relates to a spray extraction nozzle for cleaning a surface, in particular for decontaminating the surface, having a cup-shaped inner casing forming a central cleaning chamber, and having a pot-like outer casing forming an annular suction chamber annularly surrounding the central cleaning chamber a circumferential free inner end, wherein the outer housing has a circumferential free outer end, and wherein the suction chamber is circumferentially closed by placing the circumferential free outer end to the surface, further comprising at least one spray nozzle for spraying a cleaning agent in the central cleaning chamber, and with a suction port for sucking dirt from the suction chamber, wherein at the free inner end a flexible circumferential inner lip is arranged, which closes the central cleaning chamber when placed on the surface against the suction chamber, and w obei a flexible circumferential outer lip is arranged at the free outer end, which closes the suction chamber when placed on the surface to the outside.
  • DE 41 19 812 C1 describes another spray extraction nozzle in the form of a body cleaning device intended for cleaning or decontamination of body surfaces, especially in persons who have come into contact with a toxic substance.
  • the aim of the cleaning is that the supplied detergent enters into an intensive and long-lasting contact with the body surface, as possible, without the cleaning fluid and the dissolved dirt or poison substances reach the environment uncontrollably.
  • the known spray extraction nozzle has a pot-like housing which is double-walled, so that an outer wall and an inner wall form an annular space.
  • the annulus forms a suction chamber communicating with a suction port for exhausting detergent.
  • the inner wall further encloses a substantially rectangular interior, in which a spray nozzle for spraying the cleaning agent is arranged.
  • a carrier can be attached, which is equipped with a bristle ring.
  • the bristles are laterally offset from each other in adjacent rows, so that they form a labyrinthine seal of the interior, as soon as the bristle rim is placed on the body surface to be cleaned. Within the space area enclosed by the bristle rim, a cleaning by spraying and suction of the cleaning agent can then take place.
  • This known spray extraction nozzle has proven itself in the decontamination of body surfaces. However, it is not optimal for cleaning or decontaminating technical surfaces on objects and equipment. There is therefore a desire to provide a spray extraction nozzle optimized for the cleaning and in particular the decontamination of technical surfaces.
  • washing and suction nozzles for cleaning floors. Examples of such nozzles can be found in DE 2006 033 514 B3 . WO 94/06344 . EP 0 316 848 A2 or in DE 26 15 501 A1 , However, all these nozzles are more or less open systems, ie the cleaning agent is in deployed only partially encapsulated interior or even sprayed freely. Such systems are only conditionally suitable for the decontamination of contaminated and / or poisoned surfaces, if at all, since spraying, whirling up and splashing can occur through the spraying of the cleaning agent, causing the toxins to be whirled up and distributed uncontrollably. On the other hand, the use of at least partially open spraying and suction systems is necessary so that the fresh air required for suction can flow into the work area.
  • this object is achieved by a spray extraction nozzle of the type mentioned, wherein the outer lip has a first inner side and an outer second side, wherein the first and the second side are each profiled with grooves when placed on the surface Micro channels form, can be sucked through the air from the outside into the closed suction chamber, and wherein the inner lip has an inner third side and an outer fourth side, wherein the third side is profiled with grooves that form microchannels when placed on the surface by the air from the cleaning chamber can be sucked into the suction chamber, and the fourth side is smooth.
  • the new spray extraction nozzle thus has a double-encapsulated spray chamber, which is closed in the area of the surface by flexible sealing lips.
  • a circumferential inner lip encapsulates the inner spray or cleaning chamber.
  • an equally circumferential outer lip ensures that the cleaning agent is reliably held in the spray extraction nozzle, even if the cleaning agent is sprayed under high pressure in the cleaning chamber.
  • the two circumferential lips together form a double seal.
  • the cleaning agent can be liquid, gaseous or multiphase and also contain solids.
  • the inner lip and the outer lip of a rubber-like or at least rubber-like and impermeable material, so that they bend when placing the spray extraction nozzle on the surface to be cleaned and go into a planar contact with the surface to be cleaned. This creates a particularly good seal and contributes effectively to keeping larger quantities of liquid at high spray pressure in the nozzle body.
  • the flexibility of the sealing lips is so high that the sealing lips always tilt against the direction of movement of the spray nozzle when the spray nozzle is guided in a reciprocating motion over the surface to be cleaned. This helps to ensure that the spray nozzle can be guided over the surface with little effort and still good sealing.
  • the new spray extraction nozzle offers a special advantage of a design-related, three-stage cleaning of the surface, as soon as the spray nozzle is passed over the surface.
  • a surface portion to be cleaned is first sucked dry with the leading part of the annular suction chamber, i. There is a dry pre-cleaning of the surface section, are sucked in the loose particles or existing liquids. Subsequently, the surface section to be cleaned passes under the cleaning chamber. There he is sprayed with the detergent, preferably under high pressure. Due to the circumferential inner lip, the cleaning agent is held in the cleaning chamber and can act intensively on the surface portion.
  • the spray extraction nozzle If the spray extraction nozzle is moved further in the direction of movement, the surface portion passes into the rear or trailing part of the suction chamber, where the now dissolved and / or chemically deactivated particles and detached pathogenic germs, spores and other contaminants are sucked.
  • the constructive structure of the new spray extraction nozzle thus leads to a three-stage cleaning when moving the nozzle over the surface, wherein the three purification stages take place successively and separately from each other. This contributes to a very thorough cleaning or decontamination.
  • the outer lip on an inner first side and an outer second side, wherein the first and the second side are each profiled with grooves which form microchannels when placed on the surface can be sucked through the outside of the closed suction chamber.
  • This realization allows a controlled influx of fresh air into the suction chamber and thus a more efficient extraction of detergent and dirt.
  • the fresh air flowing in through the microchannels also contributes to the fact that cleaning agent can escape from the suction chamber to the outside.
  • the advantageous sealing effect of the outer lip is maintained despite fresh air supply.
  • the inner lip has an inner third side and an outer fourth side, wherein the third side is profiled with grooves when placed on the surface Form micro channels, can be sucked through the air from the cleaning chamber into the suction chamber, and wherein the fourth side is smooth.
  • the profiled third side allows a particularly effective suction of detergent in the transition region between the cleaning chamber and the rear or trailing portion of the annular suction chamber. Due to the microchannels, the cleaning agent in this area is greatly accelerated, with the result that dirt adhering to the surface is "torn away".
  • the outer fourth side acts as a wiper blade, which drives above all liquid soiling when moving the nozzle in the front or leading part of the annular suction chamber and thus ensures a very efficient "pre-cleaning". For this reason, the preferred combination of both sides profiled outer lips and one-sided profiled inner lips promises best cleaning results.
  • the new spray extraction nozzle is ideal because of these properties for decontamination of contaminated and / or poisoned technical surfaces of objects and equipment. The above object is therefore completely solved.
  • the inner housing and the outer housing are arranged substantially concentric with each other.
  • This embodiment has the advantage that the suction behavior and the cleaning efficiency of the new spray extraction nozzle are largely independent of the direction of movement relative to the surface.
  • the new nozzle can therefore be used more easily and flexibly when cleaning surfaces.
  • the outer housing encloses a substantially triangular base.
  • the largely triangular base area may correspond to an equilateral or isosceles triangle, but also include an iron mold, wherein The latter includes slightly convex outward curved edges.
  • the outer housing in other embodiments, a round, a rectangular, or about a bar-shaped base enclose.
  • the preferred triangular base area has the advantage that it is possible to conveniently and thoroughly clean both large surface areas and corners and edge areas with a nozzle geometry.
  • circumferential inner lip and / or outer lip are composed of largely rectilinear lip pieces.
  • the circumferential lips consist of individual pieces of lip which are joined together at suitable locations, in particular bump corners.
  • the use of individual largely straight-line lip pieces has the advantage that the lips can each invest optimally in changing directions of movement of the nozzle to the surface.
  • the suction chamber in the region of the surface has a suction cross section which is substantially smaller than a base area enclosed by the outer housing.
  • the suction opening of the circulating suction chamber is relatively small compared to the total area covered by the new spray extraction nozzle on the surface to be cleaned.
  • the suction chamber with respect to the base has a very narrow and preferably circumferential slot for suction of the surface.
  • the embodiment has the advantage that a partial or local lifting of the outer lip from the surface does not lead to a total pressure loss in the suction chamber. In other words, this embodiment contributes to the fact that the suction effect does not collapse in the case of one-sided and / or locally limited loss of contact with the surface to be cleaned. As a result, this embodiment contributes to a very simple and thorough cleaning.
  • the suction chamber has a cross-section which increasingly decreases in the suction direction.
  • the suction speed in the suction direction is increasingly greater.
  • This produces a steadily accelerated flow and has the advantage that drops or particles are carried along very effectively in the suction cross-section.
  • no drops or particles can deposit in the suction cross-section and thus drip or fall out after switching off the nozzle, which is especially for decontamination of surfaces of great advantage.
  • the new nozzle is suitable in this embodiment, in particular for aspirating high-viscosity liquids, such as non-aqueous decontaminants.
  • the suction chamber has a variable suction cross-section, which decreases with increasing flow velocity.
  • the suction chamber has at least partially flexible inner walls which reduce the suction cross-section with increasing flow velocity. This embodiment also helps to maintain the suction, even if the nozzle loses contact on one side and / or locally limited to the surface to be cleaned.
  • baffles are arranged in the suction chamber, which generate a circular suction flow.
  • a circular suction flow in the sense of this embodiment is at least partially tangential within the annular suction chamber. It forms a kind of "hurricane", increasing the flow speed and efficiency of the new nozzle.
  • the new spray extraction nozzle has a plurality of annular suction chambers, which are arranged substantially concentrically with each other around the cleaning chamber.
  • the new nozzle not only uses the above-described concept of a circumferential double seal and a three-stage cleaning. Rather, a triple seal, quadruple seal or the like is used, combined with an example five-step cleaning of the surface in successive chambers. In principle, some of the concentric chambers may also be used for dispensing and / or spraying other cleaning agents to achieve an even more thorough cleaning process with each movement of the nozzle on the surface.
  • the new spray extraction nozzle has a plurality of supply lines for supplying a plurality of different cleaning agents.
  • the new spray extraction nozzle has at least two supply lines and a fitting for selectively applying superheated steam, water and / or chemical cleaning agents.
  • This embodiment is particularly advantageous for the decontamination of technical surfaces.
