Abstract
The present invention provides a fan heater with a multi-stage blower fan, the fan heater including: upper and lower circular frames spaced up and down and having a perforated center; a drive motor including a drive shaft inserted into the bottom of the lower circular frame and rotating the lower circular frame; a central shaft penetrating the centers of the upper and lower circular frames, in which an outer circumferential surface of a lower end of the central shaft is supported by a radial bearing in the middle of the lower circular frame, and a heating wire is introduced from the top of a hollow inside of the central shaft, wound on an outer circumferential surface of the central shaft in a spiral direction, and then introduced into the inside of the lower end of the central shaft; blower fans fixed and supported between the upper and lower circular frames in a multi-stage manner and having a plurality of blower ribs on their circumferences; upper and lower cover plates being in contact with outer circumferential surfaces of the upper and lower circular frames; and a housing being in contact with the upper and lower cover plates to be covered thereby, and having a plurality of suction ports and a plurality of discharge ports, which are alternately perforated according to the positions of the blower fans provided in a multi-stage manner. As a result, the introduction of outside air and the discharge of warm air are performed on the same line or in the same direction, and thus it is possible to install the fan heater in accordance with the present invention at any place without regard to the installation place such as an out-of-the-way place or on the wall surface.
