JPS5755339A - Heat exchanger type ventilating device - Google Patents

Abstract

PURPOSE:To get a superior performance with a simple and mall-sized structure in a ventilating device in which a heat exchanging operation is performed between the intake air-flow and the discharged air flow by a method wherein the two air flow streams of the intake air-flow and the discharged air flow may be produced with a single vane structure and then a heat exchanging operation is performed by the vane structure. CONSTITUTION:When the vane 8 is operated by the motor 12 through shaft boss 11, the air is discharged from the outlet port 6 and at the same time another air is suctioned through the intake port 4, then fed. At this air flow, since the side plates 3 and the intake ports 4, and the outer circumferential plates 5 and the discharge ports 6 are alternatively arranged with each other, the air flow streams A and B produced at both sides of the flat plate 1 radially fixed to the boss 2 are flowed in an opposite direction to each other, resulting in producing two separate air flows of intake air and discharging air. Thus, when the intake air is fed into the interior of a room through a discharging port 16 in the ornamental frame 14 from the air intake port 19 of the out-door hood 18, the discharged air is fed out of the interior from the inlet port 15 in the ornamental frame 14 through the outlet port 21 of the out-door hood 20.
