Abstract: A refrigerator in which one of the horizontal grill-work shelves is replaced by a shallow, flat, water tank. The tank is supported by the same support brackets as the grill-work shelf it replaces. The tank bottom wall includes fore and aft extending grooves, for engagement by the support brackets. The upturned ledge at the free end of each support bracket engages a deeper groove portion at a front section of the main grooves, this groove portion extending short of the front edge of the tank. Thus, only partial forward withdrawal of the tank from the refrigerator chamber will be possible in the horizontal plane, accordingly with the play of the ledge along the deeper groove portion. This will prevent its accidental fall-out.
