  • the surface materials of the drawer cover plate 250 and the drawer 240 facing the direction of the pesticide residue removal space 210 are all made of stainless steel, thereby effectively reflecting ultraviolet rays, reducing the dead angle of ultraviolet distribution, and further improving the uniformity of ultraviolet distribution , thereby improving the effect of removing pesticide residues.
  • the storage assembly of the present invention defines the pesticide residue removal space 210 by setting the drawer 240 and the drawer cover plate 250.
  • a groove 230 is formed on the drawer cover plate 250 toward the center of the side of the pesticide residue removal space 210, and the UVC lamp
  • the tube 310 is arranged at the center of the drawer cover 250, so that the ultraviolet rays emitted by the UVC lamp 310 can evenly irradiate all positions of the pesticide residue removal space 210, thereby expanding the irradiation range and improving the effect of pesticide residue removal.
  • the storage assembly of the present invention further limits the shape and material of the groove 230 and the material of the drawer cover 250 and the drawer 240, and utilizes the reflection of light away from the ultraviolet rays emitted by the UVC lamp 310 to make it clear from the food.
  • the pesticide residues acting on the surface of the food materials in all directions up, down, left, and right further improve the effect of removing pesticide residues.

Abstract

L'invention concerne un ensemble de stockage pour un réfrigérateur. L'ensemble de stockage comprend : une boîte de stockage, dans laquelle un espace d'élimination de résidus de pesticide est défini et utilisé pour recevoir un matériau alimentaire devant être soumis à une élimination de résidus de pesticide, et une rainure est disposée sur le côté d'un couvercle de boîte de la boîte de stockage qui fait face à l'espace d'élimination de résidus de pesticide ; et un appareil d'élimination de résidus de pesticide, qui est disposé dans la rainure, qui comprend un tube de lampe UVC et un appareil de génération de plasma, et qui est conçu pour commander, en fonction d'une séquence de temps de démarrage définie, le démarrage du tube de lampe UVC et de l'appareil de génération de plasma, de façon à éliminer les composants de résidus de pesticide de l'espace d'élimination de résidus de pesticide. L'invention concerne également un appareil d'élimination de résidus de pesticide qui est disposé dans une rainure, qui est disposée dans un couvercle de boîte d'une boîte de stockage. Ledit appareil d'élimination de résidus de pesticide comprend un tube de lampe UVC et un appareil de génération de plasma, et commande, selon une séquence de temps de démarrage définie, le démarrage du tube de lampe UVC et de l'appareil de génération de plasma, de façon à éviter le problème d'un mauvais effet d'élimination de divers types de résidus de pesticide, ce qui permet d'améliorer ainsi l'effet d'élimination de résidus de pesticide.
