Abstract

PROBLEM TO BE SOLVED: To cool food or the like disposed on a tray uniformly. SOLUTION: Chilled air from an evaporator constituting a refrigeration cycle is guided and rises along a chilled air supply duct 5 and then introduced into the tray 11 via a plurality of chilled air outlets 7 and an opening 19 of the second tray frame 14. The chilled air is blown into a refrigeration chamber other than the tray 11 through outlets 15 in faces 21 of both side frame parts of the second tray frame 14. Thus, the chilled air is supplied diagonally from left and right upper sides to the food or the like on the tray 11 disposed below so that it is cooled from its upper side. Therefore, even when a tall and large food or the like is disposed, the food or the like on the tray 11 can be cooled uniformly because the chilled air is supplied diagonally from left and right upper sides. Because a metal tray plate 12 is also cooled, the food or the like on the tray 12 is cooled from its bottom side, too.
