  • the heating means for evaporating the stored water is not limited to the throw-in heater exemplified in the above embodiment, but is drawn from a cord heater wired on the outer bottom surface of the evaporating dish or a refrigeration apparatus. Other means such as a hot gas pipe may be used.
  • Wastewater to be evaporated can be applied to all wastewater in the warehouse including defrost water.
  • the temperature sensor is not limited to a thermostat.
  • the temperature value may be actually detected.
  • the evaporation heater is turned off when the detected value reaches a predetermined temperature. Control is sufficient.

Abstract

Selon l'invention, une tuyauterie de vidange (33) pour la vidange d'eau de dégivrage vers l'extérieur fait saillie à partir d'une surface arrière (10A) d'un corps de réfrigérateur (10), et un plateau d'évaporation (41) est fixé sous la tuyauterie de vidange (33). Un filament d'évaporation (60) est supporté et installé dans le plateau d'évaporation (41) au moyen d'un support (65) fixé à une extrémité d'une ouverture de surface supérieure (41A) d'un plateau d'évaporation (41). Une plaque d'obstruction (80) est formée de manière saillante sur le support (65) de manière à recouvrir une partie sous une ouverture de vidange (35) de la tuyauterie de vidange (33), et la plaque d'obstruction (80) est légèrement inclinée vers le bas vers son extrémité avant. L'eau de dégivrage vidangée à partir de l'ouverture de vidange (35) chute et est retenue dans le plateau d'évaporation (41) après collision avec la plaque d'obstruction (80). Le filament (60) favorise l'évaporation de l'eau de dégivrage pour la vidanger sous forme de vapeur montante. Au cours de la vidange, la vapeur est obstruée par la plaque d'obstruction (80) et empêchée autant que possible de circuler dans la tuyauterie de vidange (33) à partir de l'ouverture de vidange (35). Ainsi, le reflux de la vapeur dans la chambre est supprimé afin d'empêcher que la température dans le dispositif de stockage ne s'élève inutilement.
