du type electrique haute tension.high voltage electric type.

Ce type d'appareil existe de facon courante. Les insectes, attires par la lumiere, penetrent dans un caisson ouvert et se posent ou plutot tentent de se poser sur des grilles judicieusement positionnees par rapport a l'organe eclairant. Ces grilles correspondent en fait a deux electrodes qui vent alimentees chacune en courant electrique haute tension, de l'ordre de 4000 volts par exemple. Ces grilles electrodes vent placees cote a cote, legerement espacees, de telle sorte qu'un insecte qui s'en approche, cree un court-circuit entre les deux, ce qui provoque son electrocution immediate. Ce type d'appareil est regulierement visite pour proceder a ['evacuation des This type of device commonly exists. Insects, attracted by the light, enter an open box and land or rather try to land on grids judiciously positioned in relation to the illuminating organ. These grids actually correspond to two electrodes which are each supplied with high voltage electric current, of the order of 4000 volts for example. These electrodes grids are placed side by side, slightly spaced, so that an insect which approaches them, creates a short circuit between the two, which causes its immediate electrocution. This type of device is regularly visited to evacuate

cadavres et a son nettoyage.corpses and its cleaning.

Generalement, ces appareils vent equipes d'une sorte de tiroir qui collecte les insectes electrocutes. Cependant, des insectes peuvent rester colles sur les electrodes et le nettoyage de ces derrieres implique bien souvent de les demonter. Cette operation de demontage est souvent delicate, surtout lorsque ces appareils vent installes en hauteur, accroches a la partie superieure du batiment, charpente ou plafond. La presente invention propose un amenagement original pour ces appareils qui simplifient considerablement les operations d'entretien et surtout les operations liees Generally, these devices are equipped with a sort of drawer that collects electrocuted insects. However, insects can remain stuck on the electrodes and cleaning them behind often involves dismantling them. This disassembly operation is often delicate, especially when these devices are installed at a height, hanging from the upper part of the building, frame or ceiling. The present invention provides an original arrangement for these devices which considerably simplify maintenance operations and especially related operations.
