Electric heating fan

Abstract

The invention is directed to a heating fan (100) with an inner space (110) in which is arranged an air channel (810) which is partially made of plastic. An electric heating body (300) is arranged behind a fan (800) in an air flow direction (821). According to the invention, this fan is constructed such that a fan wheel (801) of a radial fan, which fan wheel (801) is contained in the fan (800), has two suction sides (805, 806) which are separated by a dividing wall (804). During operation, a first air flow (822) is sucked in from outside (1) through the first suction side (805) which is open to a first air inlet opening (221). The second suction side (806) is arranged in a fan space (111) of the heating fan (100) and is pneumatically connected to second air inlet openings (222). The fan is arranged in front of a ceramic heating element (301) of the electric heating body (300) so that the first air flow (822) and the second air flow (823) stream through the heating body (300).
