PURPOSE:To exhibit a freezing cycle capability similar to that of connecting an air discharging duct even if the air discharging duct is connected by a method wherein the number of revolution of an air discharging fan for use in discharging hot air out of a device through an air blowing port is varied in response to a signal from a duct fixing sensing sensor. CONSTITUTION:An operation lever 16 of a micro-switch 15 (a duct fixing sensor) for use in sensing an insertion of an installing member 11 is projected inside a guide member 13. The installing member 11 is inserted into the guide member 13 and an air discharging duct 10 is connected to an air discharging port 5, resulting in that the operation lever 16 is pushed by the installing member 11 and the micro-switch 15 is turned on. A control part 18 increases a rotational speed of a fan motor 19 in response to an ON signal of the micro-switch 15. With such an arrangement, an air blowing capability of an air discharging fan 2 is increased to overcome an air resistance caused by a connection of the air discharging duct 10 and thus cooling air having the same amount as that before connecting the air discharging duct 10 can be flowed to a condenser. |
