Title:
SWIRL-TYPE FAN VENTILATOR
Document Type and Number:
WIPO Patent Application WO/2014/119813
Kind Code:
A1
Abstract:
The present invention relates to a swirl-type ventilator, and more specifically, a swirl-type fan ventilator, wherein a swirler fan has a rotary plate and blades and generates swirl by the rotation thereof so as to induce a pressure difference and the air flow direction, thereby rapidly and efficiently introducing the air including external pollution sources or the like into a housing. The introduced air of the pollution sources rapidly and easily moves in the direction of an exhaust pipe by a suction fan which is provided on the same shaft as a fixed bell mouth and rotates so as to maximize the exhaust efficiency. The outside edge of the bell mouth is a curved surface which is curved in the direction of the swirler fan and the inside edge thereof forms a curved surface which is curved in the direction of the suction fan so as to increase the flow speed. Stepped portions in the height direction and the thickness direction are formed so as to facilitate the generation of the swirl and guides are provided to the outer walls of the blades of the swirler fan such that the air including the pollution sources or the like and partially dispersed by the rotation force of the blades is introduced into the housing. The swirl-type fan ventilator, according to the present invention, comprises: a housing formed in a hollow shape and having an inner diameter larger at one side end portion than the other side end portion; a motor provided to the inside of the housing; a cylindrical rotation shaft provided to the motor; the swirler fan including a rotation plate provided to the rotation shaft so as to rotate and a plurality of blades disposed along the outer peripheral surface of the rotation plate and fixed in an erected state; a bell mouth surrounding the swirler fan at the lower portion of the swirler fan; and a suction fan which is provided to the rotation shaft so as to rotate, is provided at the lower portion of the bell mouth, and is formed from the combination of a plurality of individual blades which are turned at a predetermined angle with respect to a radial direction.
