PROBLEM TO BE SOLVED: To avoid the water to be discharged that has been used for cleaning from remaining on a spacer plate.SOLUTION: A cooling unit 20 in which a cooling fan 22 and a cooler 21 are stored inside casings 35 and 25 is installed in an installation chamber 16 provided on a side of a housing chamber 15 for an object to be cooled. The chilled air, generated through heat exchange with the cooler 21 after having been sucked from a front side of the cooling unit 20, is blown out of a rear surface of the cooling unit 20, and then goes around into a side surface side, to be supplied to the housing chamber 15 by circulation. A spacer plate 50 is fitted between a lower part on the rear surface of the cooling unit 20 and a facing wall surface 16B of the installation chamber 16. A drain groove 60 is formed along depth direction at the spacer plate 50, and on the lower surface side of the cooling unit 20, a drain pan 70 which receives defrosting water from the cooler 21 is removably attached in such a manner as one side part thereof faces the lower part of the drain groove 60. |
