Abstract

Изобретение позвол ет увеличить зону обдува путем создани направленного движени потока воздуха в зоне выхода вентил тора. На валу 3 электропривода 2, установленного на основании 1, закреплен несущий элемент, имеющий форму гиперболоида вращени и выполненный в виде стержневого каркаса 4, на стержн х 5 которого консольно закреплены лопатки (Л) 6. Л 6 размещены равномерными р дами в меридиональных плоскост х. Расположенные в местах, наиболее удаленных от горизонтальной плоскости Q симметрии несущего элемента, участки Л 6 наклонены в сторону его вращени . Высота Л 6 монотонно увеличиваетс от плоскости Q. 3 ил.The invention makes it possible to increase the blowing zone by creating a directional movement of the air flow in the exit zone of the fan. On the shaft 3 of the electric drive 2, mounted on the base 1, a carrier is fixed, having the shape of a hyperboloid of rotation and made in the form of a core frame 4, on the rods x 5 of which the blades (L) 6 are cantileverly fixed. . Located in places furthest from the horizontal plane Q of symmetry of the carrier, the sections L 6 are inclined in the direction of its rotation. The height L 6 increases monotonically from the plane Q. 3 Il.

Claims

Claim

A household fan containing a base, an electric drive mounted on it, a supporting element mounted on the vertical shaft of the latter and blades cantilevered on it, placed in even rows in meridional planes, sections of which are located in places farthest from the horizontal plane of symmetry of the supporting element, tilted into the side of its rotation, and having a height monotonically increasing from the horizontal plane of symmetry of the bearing element, characterized in that, in order to increase the zones blowing, the carrier element has the shape of a hyperboloid of revolution N is configured in the form of rod-shaped skeleton, in which the rods are fixed blade.
