Abstract

An air conditioning rotating body including a rotor having a cylindrical shape. The rotor is housed in a casing so as to be freely rotatable. The casing includes a seal member. The air conditioning rotating body treats air passing through the rotor in an axial direction. The seal member extends in a radial direction of the rotor and separates air passages. An end face of the rotor in the axial direction is provided with at least one spoke in contact with the seal member. A contact point of the seal member with the spoke is configured to move in the radial direction as the rotor rotates.

First claim

The invention claimed is:

1. An air conditioning rotating body comprising:
a rotor having a cylindrical shape, the rotor being configured to be housed in a casing so as to be freely rotatable, the casing including a seal member, and the air conditioning rotating body being configured to treat air passing through the rotor in an axial direction,
the seal member including a portion that extends in a radial direction of the rotor and separating air passages,
an end face of the rotor in the axial direction being provided with at least one spoke in contact with the seal member,
the at least one spoke being provided only on the end face of the rotor in the axial direction,
a contact point of the portion of the seal member with a single spoke of the at least one spoke being configured to move in the radial direction as the rotor rotates.

2. The air conditioning rotating body of claim 1 , wherein
the at least one spoke includes a plurality of spokes, and the seal member contacts at least two of the plurality of the spokes.

3. The air conditioning rotating body of claim 1 , wherein
the at least one spoke is curved in a circumferential direction of the rotor.

4. The air conditioning rotating body of claim 2 , wherein
each of the plurality of spokes is curved in a circumferential direction of the rotor.

5. The air conditioning rotating body of claim 1 , wherein
the end face of the rotor is further provided with a reinforcing rib extending in the radial direction.

6. The air conditioning rotating body of claim 2 , wherein
the end face of the rotor is further provided with a reinforcing rib extending in the radial direction.

7. The air conditioning rotating body of claim 3 , wherein
the end face of the rotor is further provided with a reinforcing rib extending in the radial direction.

8. The air conditioning rotating body of claim 1 , wherein
the end face of the rotor is further provided with an annular member surrounding a center of the rotor circumferentially.

9. The air conditioning rotating body of claim 2 , wherein
the end face of the rotor is further provided with an annular member surrounding a center of the rotor circumferentially.

10. The air conditioning rotating body of claim 3 , wherein
the end face of the rotor is further provided with an annular member surrounding a center of the rotor circumferentially.

11. The air conditioning rotating body of claim 5 , wherein
the end face of the rotor is further provided with an annular member surrounding a center of the rotor circumferentially.

12. The air conditioning rotating body of claim 1 , wherein
the at least one spoke includes a spoke provided on each of both end faces of the rotor in the axial direction, and the spokes provided on both the end faces overlap each other when viewed from the axial direction.

13. The air conditioning rotating body of claim 2 , wherein
the plurality of spokes includes spokes provided on each of both end faces of the rotor in the axial direction, and the spokes provided on both the end faces overlap each other when viewed from the axial direction.

14. The air conditioning rotating body of claim 3 , wherein
the at least one spoke includes a spoke provided on each of both end faces of the rotor in the axial direction, and the spokes provided on both the end faces overlap each other when viewed from the axial direction.

15. The air conditioning rotating body of claim 5 , wherein
the at least one spoke includes a spoke provided on each of both end faces of the rotor in the axial direction, and the spokes provided on both the end faces overlap each other when viewed from the axial direction.

16. The air conditioning rotating body of claim 8 , wherein
the at least one spoke includes a spoke provided on each of both end faces of the rotor in the axial direction, and the spokes provided on both the end faces overlap each other when viewed from the axial direction.

17. An air treatment device including the air conditioning rotating body of claim 1 .

18. An air treatment device including the air conditioning rotating body of claim 2 .

19. An air treatment device including the air conditioning rotating body of claim 3 .

20. An air treatment device including the air conditioning rotating body of claim 5 .
