Title (EN) AIR-AMPLIFYING FAN
(FR) VENTILATEUR D'AMPLIFICATION D'AIR
(KO) 공기 증폭형 선풍기
Abstract:
(EN) An air-amplifying fan includes a blast pipe having a guide hole longitudinally penetrating the center of the pipe. An air flow means is provided in a base positioned at the lower part of the blast pipe, and an inflow passage is formed at the front of the inside of the blast pipe and the base, and a discharge passage is formed at the rear of the inside thereof. External air flows in through an inlet, formed at the top of the front of the blast pipe, so as to be suctioned by the air flow means, and is discharged therefrom again so as to be discharged through an outlet formed at the rear of the blast pipe toward the guide hole. The external air is guided to the guide hole and moved forward by the rapid flow of the air discharged to the outlet. The present invention reduces noise spreading to the outside through the inlet by providing the inlet at a distance far away from a motor and a blowing fan, and also provides the fan with reduced noise by connecting the plurality of blowing fans to the motor so as to discharge a sufficient amount of air, even though the motor is driven at a low rotational speed.
(FR) L'invention concerne un ventilateur d'amplification d'air, lequel ventilateur comprend un tuyau de soufflage pourvu d'un trou de guidage pénétrant longitudinalement dans le centre du tuyau. Des moyens de circulation d'air sont disposés dans une base positionnée au niveau de la partie inférieure du tuyau de soufflage, un passage d'entrée d'air est formé à l'avant de l'intérieur du tuyau de soufflage et de la base, et un passage d'évacuation est formé à l'arrière de l'intérieur de ces derniers. De l'air externe s'introduit par un orifice d'entrée formé au sommet de l'avant du tuyau de soufflage, de manière à être aspiré par les moyens de circulation d'air, puis est évacué à nouveau de ces derniers de manière à être évacué par un orifice de sortie formé à l'arrière du tuyau de soufflage vers le trou de guidage. L'air externe est guidé vers le trou de guidage et déplacé vers l'avant par la circulation rapide de l'air évacué vers la sortie. La présente invention permet de réduire le bruit émis vers l'extérieur à travers l'orifice d'entrée en disposant l'orifice d'entrée à une distance éloignée d'un moteur et d'un ventilateur de soufflage, et permet également de réduire le bruit du ventilateur en connectant la pluralité de ventilateurs de soufflage au moteur de façon à évacuer une quantité d'air suffisante, même si le moteur est entraîné à une faible vitesse de rotation.
(KO) 공기 증폭형 선풍기는 관 중심을 전후로 관통하는 유인구가 형성된 송풍관을 포함한다. 송풍관의 하방에 위치한 베이스에 공기유동수단이 구비되고, 송풍관과 베이스의 내부 전방측에 유입통로, 내부 후방측에 토출통로가 형성된다. 송풍관의 전방측 상방에 형성된 유입구를 통해 외부 공기가 유입되어 공기유동수단으로 흡입되고 다시 배출되어 송풍관의 후방에 유인구쪽으로 형성된 토출구를 통해 배출된다. 토출구로 배출되는 빠른 공기흐름에 의해 외부공기가 유인구로 유인되어 전방으로 이동한다. 본 발명은 유입구를 모터와 송풍팬으로부터 먼 거리에 설치하여 유입구를 통해 외부로 확산되는 소음을 저감한다. 또한, 모터에 복수의 송풍팬을 연결하여 모터가 낮은 회전속도로 구동됨에도 불구하고 충분한 풍량을 토출하여 소음이 저감된 선풍기를 제공한다.
