  • a chamber cleaning machine in which the small components to be cleaned are introduced into a cleaning chamber by means of a basket trolley, in which, above the basket trolley, z. B. also in household machines known manner a circumferential nozzle tube with downward spray nozzles is arranged.
  • Such a machine is not suitable for cleaning complicated workpieces and in particular for cleaning tightly packed bulk goods.
  • the cleaning system known from US Pat. No. 4,370,992 is more suitable for this application, in which a drum is rotatably arranged in a closed chamber, into which the containers holding the bulk material can be inserted. Above the revolving drum, nozzle pipes are arranged, through whose nozzles directed towards the drum the cleaning liquid is sprayed for the purpose of spray cleaning.
  • This cleaning system does not guarantee optimal cleaning, particularly in the case of workpieces of complex construction, in particular if an aqueous cleaning liquid is used while avoiding aggressive chemicals.
  • the present invention proceeds in its construction a cleaning system of the type known from FR 2 597 767 A1, the features of which are common to the invention are specified in the preamble of claim 1.
  • the parts loading unit according to claim 2 is proposed, which can advantageously be flooded with flood pipes according to claim 3.
  • Such a system is universal for various cleaning tasks such as Spray, flood and immersion cleaning can be used.
  • a workpiece carrier floor can be inserted into the parts loading unit, which is stationary in this case, while the spray cleaning unit performs a rotational movement around the parts loading unit while dispensing the cleaning liquid.
  • shock-resistant individual parts can also be cleaned in the form of bulk goods, they can be placed in a container perforated walls and lid are introduced and this is inserted into the parts loading unit, which in turn is set in rotary motion.
  • this parts loading unit is designed in the manner of a cage, so that the jets of the rotating spray cleaning unit strike the workpiece or the container to be cleaned at different angles.
  • Claim 8 relates to an appropriate arrangement of the flood pipes.
  • the invention proposes a very variable cleaning system which enables both spray cleaning in the permanently rotating system and flood cleaning, the workpieces to be cleaned being able to be present both in the form of individual parts and in batches. This creates all the prerequisites for the best possible cleaning results, even on a water chemical treatment basis achieve so that a consistently environmentally friendly concept can be realized with the system according to the invention. Despite the increasing variety of parts, almost all cleaning and degreasing problems can be solved in the industrial and craft sector.
  • a particular advantage is that the usable space of the system according to the invention can be designed for workpiece carriers as well as for Euro standard containers with the dimensions 600 x 400 x 280 mm. Both closed and open-walled containers can be used depending on the drive of the parts loading unit.
  • FIGS. 1, 2, 3 and 4 A first exemplary embodiment shown in FIGS. 1, 2, 3 and 4 is explained in more detail below.
  • the system for cleaning and degreasing workpieces according to the invention is, as illustrated with FIG. 1, housed in a closed chamber 10 which is placed on a base cabinet 60.
  • the base cabinet 60 comprises a collecting container 62 with bath care devices for the cleaning liquid, which are not shown in detail.
  • a control cabinet 61 accommodating the control is attached to the chamber 10.
  • the cleaning liquid applied in the chamber 10 is essentially collected by the baffle plate 12 and passed through the outlet 19 into the collecting container 62.
  • the workpieces or the like (not shown) to be cleaned are located in a container 50, which preferably has the size of a Euro standard container of 600 x 400 x 280 mm.
