Abstract
(EN)
The purpose of the present invention is to provide an air blowout apparatus such that it is possible to ensure the stable volume of blowout air even if the airflow formed within a duct is either in a first state or in a second state. A first airflow (F1) flows between a first airflow deflection member (13) and a first wall (121), and a second airflow (F2) flows between the first airflow deflection member and a second wall (122). The first airflow deflection member performs switching between a first state in which the speed of the first airflow is higher than that of the second airflow and a second state in which an airflow different from that in the first state is formed. A guide wall (14), which is the portion of the first wall towards the blowout port side, bends the first airflow in the first state along the wall surface and guides the first airflow to the first wall from the second wall. A second airflow deflection member (15) is located downstream from the first airflow deflection member in the air flow direction. The second airflow deflection member deflects the second airflow in the first state toward the first wall from the second wall. The second airflow deflection member makes the degree of deflection of the second airflow toward the first wall from the second wall in the second state lower than in the first state, or prohibits the deflection of the second airflow toward the first wall from the second wall.

Le but de la présente invention est de produire un appareil de soufflage d'air de telle sorte qu'il est possible de garantir le volume stable d'air de soufflage même si le flux d'air formé à l'intérieur d'un conduit est soit dans un premier état, soit dans un second état. Un premier flux d'air (F1) s'écoule entre un premier élément de déviation de flux d'air (13) et une première paroi (121), et un second flux d'air (F2) s'écoule entre le premier élément de déviation de flux d'air et une seconde paroi (122). Le premier élément de déviation de flux d'air effectue une commutation entre un premier état dans lequel la vitesse du premier flux d'air est supérieure à celle du second flux d'air et un second état dans lequel un flux d'air différent de celui du premier état est formé. Une paroi de guidage (14), qui est la partie de la première paroi vers le côté orifice de soufflage, courbe le premier flux d'air dans le premier état le long de la surface de paroi et guide le premier flux d'air vers la première paroi à partir de la seconde paroi. Un second élément de déviation de flux d'air (15) se situe en aval du premier élément de déviation de flux d'air dans la direction du flux d'air. Le second élément de déviation de flux d'air fait dévier le second flux d'air dans le premier état vers la première paroi à partir de la seconde paroi. Le second élément de déviation de flux d'air rend le degré de déviation du second flux d'air vers la première paroi à partir de la seconde paroi dans le second état plus faible que dans le premier état, ou empêche la déviation du second flux d'air vers la première paroi à partir de la seconde paroi.
