The second support portion and the first support portion are manufactured separately.

First claim

What is claimed is:

1. A middle air duct support member of an air conditioner, comprising:
an annular first support portion;
an annular second support portion arranged at an axial end of the annular first support portion, wherein the annular second support portion and the annular first support portion are manufactured separately; and
a reinforcement plate provided on one of the annular first support portion and the annular second support portion,
wherein the reinforcement plate is provided between the annular first support portion and the annular second support portion and is configured to abut against the other one of the annular first support portion and the annular second support portion,
wherein the reinforcement place is provided on an inner peripheral wall of the annular first support portion,
wherein the reinforcement plate is folded in an axial direction after extending inwardly in a radial direction, and
wherein at least part of the annular second support portion extends into the annular first support portion and part of the inner peripheral wall of the annular first support portion and a free end of the reinforcement plate abut against an outer peripheral wall of the annular second support portion.

2. The middle air duct support member of the air conditioner according to claim 1 , further comprising:
a first stepped portion provided on the inner peripheral wall of the annular first support portion; and
a second stepped portion abutting against the first stepped portion and provided on the outer peripheral wall of the annular second support portion.

3. The middle air duct support member of the air conditioner according to claim 2 , wherein the annular second support portion comprises:
an annular chassis arranged on an end surface of an axial end of the annular first support portion;
an annular first connecting section having one end connected to a radial inner end of the chassis and the other end extending into the annular first support portion in the axial direction;
an annular second connecting section having one end connected to the other end of the first connecting section and the other end extending inwardly in the radial direction; and
an annular third connecting section having one end connected to the other end of the second connecting section and the other end extending in the axial direction away from the first connecting section,
wherein the second connecting section and the third connecting section define the second stepped portion and the free end of the reinforcement plate abuts against the other end of the third connecting section.

4. The middle air duct support member of the air conditioner according to claim 1 , wherein the reinforcement plate is configured to extend in a circumferential direction to form an open-loop shape.

5. The middle air duct support member of the air conditioner according to claim 1 , further comprising a decorative member arranged on at least one of the outer peripheral walls of the annular first support portion and the outer peripheral walls of the annular second support portion.

6. The middle air duct support member of the air conditioner according to claim 5 , wherein the decorative member comprises:
a decorative board detachably arranged on the outer peripheral wall of the annular first support portion; and
a light source box provided between the decorative board and the outer peripheral wall of the annular first support portion, a light-emitting strip being provided in the light source box.

7. The middle air duct support member of the air conditioner according to claim 6 ,
wherein the annular first support portion is defined with screw holes;
wherein an inner surface of the decorative board is provided with screw studs that are fitted with the screw holes; and
wherein the screw stud is defined with a notch running through the screw stud along an axial direction of the screw stud.

8. An air conditioner comprising the middle air duct support member according to claim 1 .
