Vortex air outlet device

Abstract

The invention discloses a cyclone air outlet device, which is characterized by the following: placing multiple blades in the opening region of air outlet host to do free inclining movement around radiation shape axis; adjusting the inclined angle of each blade through the driving device movement; changing flow direction through blade; controlling the interflow of each blade as cyclone state; strengthening the vertical downward speed component of flow through increasing the inclined angle of blade; strengthening transverse speed component through decreasing the inclined angle of blade; selecting the discharging state ranged from vertical direction to transverse direction corresponding to each air adjustment condition.

Description

technical field [0001] The present invention relates to an air outlet device arranged facing a space to be air-conditioned, especially a swirling air outlet device that can properly adjust the swirling discharge state of airflow by simply controlling the inclination angle of the vane plate. Background technique [0002] In air-conditioning equipment, the air outlet device that discharges the conditioned air sent through the duct to the indoor space that is the space to be air-conditioned is generally used as a device that makes the air flow of the conditioned air flow straight in one or more directions. , In addition, there is also a device that makes the direction of a plurality of exhaust airflows coincide with the tangential direction of a circle, and generates a rotational velocity component by the confluence of each airflow, and discharges it as a swirling flow. This mechanism for discharging conditioned air as a swirling flow is configured by setting leaf-shaped valves...

Problems solved by technology

[0005] The existing swirl air outlet device is constituted as described above, although the position adjustment of the movable vane part 103 is adjusted to change the state in which the conditioned air is discharged as a swirl flow, but the position of each vane body of the fixed vane part 102 and the movable vane part 103 The angle of inclination is always fixed, and the airflow cannot be reliably guided in the desired direction only by adjusting the position of the movable vane part 103

In particular, for the velocity component in the horizontal direction of the airflow, not only the degree of guidance of the blade body is increased and the rotational velocity component is strengthened, but also the Coanda effect caused by the shape of the surface part 104 is used to the maximum extent, and the direction of the airflow is directed toward the horizontal direction. Therefore, it is easy to be affected by the surrounding environment of the air outlet. Even in normal occasions, it is difficult to make the air flow completely face the horizontal direction, and become a slightly downward discharge state. Moreover, in order to make the exhaust air flow in the The function of continuously changing between horizontal discharge and vertical discharge can be reliably performed, but it is necessary to protrude the air outlet by a specified size from the ceiling, etc., and there are many problems in terms of aesthetics

Moreover, in the case where it does not protrude from the ceiling, even if the rotation adjustment of the movable blade part 103 is continuously performed, the discharge state is still limited to the two stages of horizontal and vertical, and there is the above-mentioned problem.

Furthermore, in a state where the vanes of the movable vane unit 103 are positioned between the fixed vanes of the fixed vane unit 102, the mechanism for turning the movable vane unit 103 is complicated and expensive.
