Definitions

  • the present invention generally relates to an apparatus and method for cleaning planar surfaces, using a high pressure cleaner.
  • the apparatus comprises rotary high pressure nozzles capable of cleaning the surface and an integrated suction system capable of picking up the cleaning liquid.
  • the suction system is also driven by the cleaning liquid.
  • US 4 895 179 involves a surface cleaner, having a peripheral liquid collection region integrated into the housing.
  • the nozzle is oriented towards the collection region.
  • the cleaning liquid is sucked up by venture device, which provides the pumping/suction of the cleaning liquid.
  • This solution suffers from several weaknesses, when being used together with a consumer high pressure cleaner with limited pressure and flow (typically limited by the electrical supply available i.e. 230V and 10-16A in Europe).
  • the surface cleaner in US 4 895 179 is to be used with a pressure of 207 to 345 bar and flow of 23 to 38 1/min, where consumer high pressure cleaners are typically in the range of 80 to 120 bar and 5 to 81/min.
  • the cleaning apparatus can thus 100% clean, 100% suck or a combination of the two.
  • the object of the present invention can be accomplished by a system as described in the introductory part of claim 1, consisting of a standard surface cleaner consisting of housing with handle and a connection to a pressure source e.g. high pressure cleaner.
  • the cleaning liquid from the pressure source is via a swivel connected to an arm that rotates inside the housing.
  • a swivel connected to an arm that rotates inside the housing.
  • To the arm typically at the ends) one of more primary nozzles can be connected.
  • the primary nozzles are tipped compared to the swivel (centre of rotation) and thereby creating a self-propelling rotary movement around the swivel.
  • the high velocity jet from the primary nozzles when rotating above the cleaning surfaces, makes the cleaning effect.
  • To the pressure source is also connected one or more secondary nozzles used to create a vacuum in a suction manifold. Cleaning liquid not being drained during cleaning can then be sucked up by the cleaning apparatus and led to a proper drain via a connection hose connected to the suction outlet of the cleaning apparatus.
  • a primary valve is integrated which is used to direct the cleaning liquid to the primary nozzle(s) and/or secondary nozzle(s). If 100% power to cleaning is needed, the cleaning liquid is via the primary valve only led to the primary nozzle(s). If 100% power to sucking of cleaning liquid is needed the cleaning liquid is via the primary valve directed only to the secondary nozzle(s). Any combination of suction and cleaning is possible by adjusting the primary valve.
  • a secondary valve is integrated which is used to close the suction outlet connection on the cleaning apparatus.
  • the spool inside the primary valve has the same diameter at both ends, where it is sealed. This will make the spool pressure compensated.
