PROBLEM TO BE SOLVED: To make it possible to uniformly conduct cold storage irrespective of the position of placed food by sensing the temperatures of the sections in a cold storage chamber, judging the part to require for cooling and the part to require for no cooling, and moving the position of chilled air discharge to the part required for cooling. SOLUTION: A cylindrical cold storage chamber duct 114 is provided at the rear of a duct cover 111, and chilled air discharge ports 115a, 115b are formed at the positions communicating with the chilled air outlets 112 of the respective stages on the circumferential surface of the duct 114. The large ports 115a and relatively small ports 115b are compositely arranged at the respective rows. The duct 114 is fixed to a rotary board 117 rotating by the driving force of a motor 116. The motor 116 is driven by the signal of a CPU for processing the signals of temperature sensors 113 provided at the respective stages. Thus, it senses the site where the temperature is highest, thereby making it possible to discharge the large quantity of chilled air only to the stage. |
