  • Patent number: 5839953
    Abstract: A mechanism for controlling the flow of air from an air-conditioning unit includes a row of guide vanes which are pivotally held by an outlet nozzle. The guide vanes are located at the lower end of an air course which has been formed within a body of the air-conditioning unit. The guide vanes control the flow of air in both left and right directions. This new design is characterized in that the angle of inclination of each guide vane progressively changes toward the end of the row. The air flow is controlled accurately in both the left and right directions so that the air flow reaches the desired location.
