Abstract

Apparatus which accelerates the cooling of the stored water cooled in the storage tank after a refilling operation so that it corresponds to the temperature that is normally reached after a relatively long water storage period. The apparatus includes a carbonator tank having at least one spray opening in the water feed line leading into the head-space region of the carbonator storage tank and where the spay opening is directed to the side walls of the tank in the vicinity of an ice bank formed on an upper inner wall surface thereof. An additional spray opening is oriented so that it points directly at the water surface and by a relatively simple valving arrangement both downward and/or lateral sprays can be implemented. The present invention also includes an arrangement where an adjustable spray guide element is located inside the storage tank in the immediate vicinity of a water feed opening so that a guiding of the sprayed water can be provided either toward the ice bank or directly toward the water surface inside the tank.
