Air-conditioning machine

Abstract

Abstract PURPOSE:To elongate the arrival distance of blow-off air, by a method wherein one part of the blow-off side of a casing for a fan is projected toward the inside of a room and an inward a cute cut-and-raised part, beginning from the upstream side of air, is formed on the substantially half of the side of the fan of the projecting part while a projecting round part is provided in the cut- and-raised part. CONSTITUTION:Air, sucked through a suction port 16, is heated (or cooled) by a heat exchanger 17a, thereafter, is sent out by a fan 18a and is blown off through a blow-off port 11a while being controlled in the direction thereof by a louver 12a. A negative pressure is generated in the air at openings 23, 25 since a cut-and-raised part 20a-1, 20a-2 is acute. Resistance against a main flow is small since the cut-and-raised part 20a-1, 20a-2 is provided with an projecting round part at the inside of the same, therefor, the resistance against the main flow is small and the speed of the air will never be deteriorated. According to this constitution, the arrival distance of the blow-off air may be elongated and a comfortable space may be formed.
