PURPOSE:To enable the most suitable air conditioning and little generation of noise by installing a ring-like plate which comprises an open and a closed parts and rotates freely at a ring-like blow-off opening installed in an outer circumferential part of a suck-in hole. CONSTITUTION:When a blower 2 rotates by a driven motor 4, room air sucked in through a suck-in hole 5 is sent to a coil 3 via an air filter 10, a guide cylinder 7, and a guide plate 15. This room air exchanging heat at the coil 3 flows down between a casing 1 and a baffle plate 6a and blows off through a blow-off hole 8 via an open part 16a of a ring-like plate 16. Thus, as the ring-like plate 16 is placed in a blow-off passage in a wtatable manner, wind blown off from the blow-off hole 8 is enabled to blow in any optional direction of 360 deg. by corresponding to the location of the open part 16a and the most suitable air conditioning enviroment is realized. Effects such as little wind loss due to the ring-like plate and little noise etc. are obtained. |
