Patent ID: 8212187

Claim:
A portable space heater comprising; a housing comprising; a wall defining an interior space; an air inlet located in a lower portion of said housing; an air outlet located in an upper portion of said housing; a base supporting said housing relative to a support surface; an electric motor disposed within said interior space; an impeller rotatably disposed within said interior space between said air inlet and said air outlet, said impeller connected to and rotated by said electric motor; a rotational engine disposed within said interior space; an air stream deflector rotatably disposed within said interior space between said impeller and said air outlet, said air stream deflector operatively coupled to said rotational engine, said air stream deflector extending at least partially within said upper portion of said housing and toward said air outlet; a drive operatively coupled between said air stream deflector and said rotational engine, wherein said rotational engine rotates said drive thereby causing said air stream deflector to rotate; an axis of rotation about which said air stream deflector is rotated, said axis of rotation comprising a substantially perpendicular axis of rotation relative to said support surface; an electric heating element disposed within said interior space between said impeller and said air stream deflector; a heated air stream exiting said interior space through said air outlet and projected substantially radially outward from said housing; a flow path of said heated air stream exiting said interior space comprising a substantially parallel flow path relative to said support surface; and wherein said air stream deflector may be rotated using said rotational engine to cause said flow path of said heated air stream to move relative to said base.
