Abstract
Electric air impeller characterized by the fact being made up of an electromotor with a vertical axis supported on a circular base which, together with an upper casing body, makes up the casing of the apparatus, electrical resistances mounted on stable insulating supports and located in front of an upper opening in the casing itself. enclosure protected by a grid while the upper end of said motor shaft It is attached to a rotating frame made up of a turbine and a concave bottom plate. Fins that channel the outgoing air are arranged in the peripheral zone that separates the base and the aforementioned enclosure. The apparatus is controlled by a command button that establishes the situations. for stopping and running the motor and the stepped connection of the resistors, a folding handle element being applied to the housing of the apparatus so that the penetration of ambient air into the apparatus determined by the suction of the turbine takes place axially through the opening upper part of the envelope, passing through the area of the electrical resistances to heat up in the event of their being connected and being oriented radially by the turbine towards the peripheral fins that eject it throughout the entire contour of the apparatus as a portion of the sucked air enters the space in which the motor is located in order to cause its ventilation and passing through a narrowing formed by the base and the rotating bottom plate is peripherally expelled by the friction of the latter to make it merge with the mass of air leaving the turbine for the projected set to the outside.
