PROBLEM TO BE SOLVED: To efficiently defrost a cooler by eliminating stopping of a blower, even if a door is opened when defrosted. SOLUTION: The cold insulation cabinet comprises a heat insulation cabinet body 1 opened in an overall surface, a cooler 2 for cooling in the cabinet, a blower 3 for circulating the air in the cabinet, a heater 4 for overheating the cooler 2 when defrosted, a control panel 5 for operating a button, displaying a lamp or the like and a controller 6 for controlling an operation of the blower 3. Thus, even in any of a first defrosting mode for operating the blower 3 and the heater 4 selectively as needed and a second defrosting mode for operating only the blower 3, the cabinet is formed so as not to stop the blower 3 by opening a door 1a. Thus, since the blower is not stopped even by opening the door during the defrosting operation, an atmosphere can be input by opening the door, thereby accelerating the defrosting, and the defrosting using the blower can be extremely efficiently conducted. |
