3. The air delivery device according to claim 2 , wherein the at least one deflecting device acts on an intake flow of the air being directed from the at least one air intake opening of the housing to the impeller in order to deflect the intake flow of the air from the intake direction at the at least one air intake opening oriented at least partly along the plane of rotation of the impeller to the inlet direction in the impeller directed at least partly along the axis of rotation.

4. The air delivery device according to claim 3 , wherein the at least one deflecting device is provided for acting on a blowing flow of the air directed from the impeller to the at least one blowing opening in order to deflect the blowing flow of the air from an exit direction from the impeller oriented at least partly along the plane of rotation of the impeller to a direction of motion having at least one directional component along the axis of rotation of the impeller.

5. The air delivery device according to claim 4 , wherein the impeller is entirely covered by the housing when looking along the axis of rotation of the impeller at one intake side of the impeller.

6. The air delivery device according to claim 5 , wherein the at least one intake opening of the air delivery device, or a plurality of smaller intake openings, extends around the impeller by an angle of at least 270° or more, the angle pertaining to one revolution about the axis of rotation of the impeller, to draw air into the air delivery device from a surrounding area.

7. The air delivery device according to claim 1 , wherein the at least one deflecting device is provided for acting on a blowing flow of the air directed from the impeller to the at least one blowing opening in order to deflect the blowing flow of the air from an exit direction from the impeller, so that the air is oriented at least partly along the plane of rotation of the impeller to a direction of motion having at least one directional component along the axis of rotation of the impeller.

8. The air delivery device according to claim 1 , wherein the impeller is entirely covered by the housing when looking along the axis of rotation of the impeller at one intake side of the impeller.

9. The air delivery device according to claim 8 , wherein the at least one deflecting device covers the impeller.

10. The air delivery device according to claim 1 , wherein the at least one blowing opening or at least one cross section through an air deflecting strut lie at least essentially in a plane through which the axis of rotation of the impeller passes.

11. The air delivery device according to claim 1 , wherein the at least one intake opening of the air delivery device, or a plurality of smaller intake openings, extends around the impeller by an angle of at least 90°, the angle pertaining to one revolution about the axis of rotation of the impeller, to draw air into the air delivery device from a surrounding area.

12. The air delivery device according to claim 1 , wherein the at least one intake opening and the at least one blowing opening are located at least partly in different angle sections with respect 4 to the axis of rotation of the impeller of the air delivery device.

13. An air conditioner, wherein the air conditioner includes the air delivery device according to claim 1 .

14. The air conditioner according to claim 13 , wherein the air conditioner has at least one air directing device, which is arranged at least partly in the plane of rotation of the impeller or parallel to it, and which is connected to the at least one intake opening of the air delivery device, in order to transport air from the air directing device into the air delivery device.

15. A seat with the air delivery device according to claim 1 .

16. A seat with the air delivery device according to claim 1 , wherein a flow path of the air comprises:

a) the air flowing into the at least one air intake opening oriented at least partly along the plane of rotation of the impeller;

b) the air flowing into the impeller in the inlet direction parallel to the axis of rotation of the impeller; and

c) the air flowing into the at least one blowing opening in an exit direction oriented at least partly along the plane of rotation of the impeller.

17. A vehicle with the air delivery device according to claim 1 .

18. The air delivery device according to claim 1 , wherein a flow path of the air comprises:

a) essentially axial intake of the air into the impeller relative to the axis of rotation of the impeller; and

b) essentially radial expulsion of the air from the impeller relative to the axis of rotation of the impeller.
