Abstract
An air cooling-type refrigeration device includes a device body, an air cooling system attached to the device body, and a drawer which may be pulled out relative to the device body, the drawer being capable of receiving cold air provided by the air cooling system, so as to cool an object stored in the drawer. The air cooling-type refrigeration device further comprises a magnetic field generating apparatus and a detection apparatus. When the magnetic field generating apparatus is powered on, a magnetic field acting on the object stored in the drawer is generated. The detection apparatus is used to detect whether the drawer is pulled out. The magnetic field generating apparatus and the detection apparatus are configured such that the magnetic field generating apparatus is powered off when the detection apparatus detects that the drawer is pulled out.
