JPS56945A - Air-conditioning device - Google Patents

Abstract

PURPOSE: To obtain an air-conditioned space with little distribution of indoor temperatures by periodically changing a blow-out angle and a blow-out velocity of the conditioned air.

CONSTITUTION: A suction port 4 is provided in the upper part of the front of a main body 1, while a blow-out port 5 being provided in the lower part thereof. In the blow-out port 5 are provided a wind-direction shifting device 6 which changes a blow-out angle periodically and a blow-out velocity changing device 7 which changes the blow-out velocity also periodically. When a low-speed motor 12 is rotated, the area of the blow-out port is changed periodically by the reciprocating motion of a slide nozzle 14 and simultaneously the blow-out angle is changed periodically in the right and left direction of an apparatus by the reciprocating motion of a vertical vane 16. Since one rotation of the low-speed motor 12 brings about one reciprocation of the slide nozzle 14 and five reciprocations of the vertical vane 16, the cycle of the wind direction becomes five times as many as that of the wind velocity. Accordingly, the blow-out velocity at the same blow-out angle changes in consecutive order, thus an conditioned space of wide range and with little distribution of the indoor temperature being obtained.
