  • the top wall 22 also closes the separation space 62 at the top.
  • the separation space 62 is designed in such a way that incoming particles are slowed down on the wall 72 and thus lose their kinetic energy. A backflow of particles back into the interior 18 can thereby be largely avoided, especially since the backflow is directed against the supply flow through the outlet opening 60 should be.

In this way, a loading pattern, shown schematically in FIG. 7, can be achieved on the surface of the component 28 as a result of the superimposed rotational movements of the component 28 and the nozzle device 86, with a view to cleaning the component 28 as completely as possible.

  • the delta robot 104 can, for example a plurality of variable position and / or variable length support elements 106 for the nozzle device 86. This gives the possibility of positioning the nozzle device 86 in the interior space 18 in such a way that the cleaning fluid discharged can be aimed specifically at the component 28.
  • a rotation of the nozzle device 86 shown here as a rotation about an axis of rotation 108, and / or a translational movement in preferably three spatial directions, independently of one another, is preferably possible.

Abstract

La présente invention concerne un dispositif de nettoyage permettant de nettoyer, en particulier, des composants (28) électriques au moyen d'un agent nettoyant sous forme gazeuse. Le dispositif de nettoyage comprend une chambre de nettoyage (12) ayant un espace interne (18) et une paroi (16) entourant celui-ci, un logement (30) pour le composant (28) dans l'espace interne (18) et un dispositif d'écoulement (34) pour l'agent nettoyant, qui comporte un dispositif de génération de pression (14) et comporte ou forme au moins un orifice d'entrée (44, 46) dans l'espace interne (18) ainsi qu'au moins un orifice de sortie (42) de l'espace interne (18). Le dispositif d'écoulement (34) permet de produire une différence de pression entre le ou les orifices d'entrée (44, 46) et le ou les orifices de sortie (42), et le dispositif d'écoulement (34) est formé de sorte que l'agent nettoyant forme un écoulement tourbillonnaire (54, 56) au moins par secteur dans l'espace interne (18) entre le ou les orifices d'entrée (44, 46) et le ou les orifices de sortie (42).
