Abstract

An air flow direction adjusting device of an air-conditioning apparatus includes: a base member including attachment shafts; air flow direction adjusting members individually attached to the attachment shafts such that the air flow direction adjusting members are allowed to rotate; and a link plate configured to rotate the air flow direction adjusting members in an interlocked manner. At least one of the air flow direction adjusting members includes a rotation shaft attachment portion attached to the corresponding one of the attachment shafts, a link plate engagement portion to be engaged with the link plate, and an operation member attachment portion to which a manual operation member for manually adjusting orientation of the air flow direction adjusting members is attached. The manual operation member is not attached to at least one of the air flow direction adjusting members.

First claim

The invention claimed is:

1. An air flow direction adjusting device of an air-conditioning apparatus, the air flow direction adjusting device comprising:
a base member including a plurality of attachment shafts projecting from an air passage surface forming an air passage of the air-conditioning apparatus;
a plurality of air flow direction adjusting members individually attached to the attachment shafts such that the plurality of air flow direction adjusting members are allowed to rotate; and
a link plate configured to connect the plurality of air flow direction adjusting members to one another such that the plurality of air flow direction adjusting members rotate in an interlocked manner, wherein
each of the plurality of air flow direction adjusting members includes
a rotation shaft attachment portion attached to a corresponding one of the attachment shafts,
a link plate engagement portion engaged with the link plate, and
an operation member attachment portion to which a manual operation member for manually adjusting orientation of the air flow direction adjusting members is attachable, and

the base member includes
a housing comprising a recess disposed at a location corresponding to one of the air flow direction adjusting members to which the manual operation member is attached, the recess configured to provide clearance for the manual operating member when the manual operating member is attached to the one of the plurality of air flow direction adjusting members and configured to house the manual operation member, and
an attachment-inhibiting portion that is located at a location corresponding to another one of the plurality of air flow direction adjusting members to which the manual operation member is not attached and that hinders attachment of the manual operation member.

2. The air flow direction adjusting device of the air-conditioning apparatus of claim 1 , wherein
the manual operation member includes a handle at an end and a clip holding the operation member attachment portion at the other end, and
the housing houses the handle of the manual operation member.

3. The air flow direction adjusting device of the air-conditioning apparatus of claim 1 , further comprising
a driving unit configured to move the link plate, wherein
the link plate includes an attachment inhibiting projection that is located at a location corresponding to the housing and inhibits attachment of the manual operation member to one of the air flow direction adjusting members.

4. The air flow direction adjusting device of the air-conditioning apparatus of claim 1 , wherein
the link plate includes a rotation regulating projection that is located to a side of one of the air flow direction adjusting members and projects toward the air flow direction adjusting members, and
when the one of the air flow direction adjusting members rotates to a rotation limit amount, the rotation regulating projection comes into contact with the one of the air flow direction adjusting members.

5. The air flow direction adjusting device of the air-conditioning apparatus of claim 1 , wherein
each of the plurality of air flow direction adjusting members further includes a first guide flat plane extending in a direction intersecting a rotation axis of the rotation shaft and a second guide flat plane facing the first guide flat plane, and
when being attached to one of the air flow direction adjusting members, the manual operation member is supported by the first guide flat plane and the second guide flat plane.

6. The air flow direction adjusting device of the air-conditioning apparatus of claim 5 , wherein
each of the air flow direction adjusting members has a notch at an outer edge,
the link plate engagement portion includes a cylindrical portion projecting from the first guide flat plane toward the notch and a conical portion located at a tip of the cylindrical portion and having a diameter larger than an outer diameter of the cylindrical portion, and
the manual operation member is engaged with an engagement portion located at an edge of the notch between the first guide flat plane and the second guide flat plane.

7. An air-conditioning apparatus comprising
an air flow direction adjusting device of the air-conditioning apparatus, the air flow direction adjusting device including:
a base member including a plurality of attachment shafts projecting from an air passage surface forming an air passage of the air-conditioning apparatus;
a plurality of air flow direction adjusting members individually attached to the attachment shafts such that the plurality of air flow direction adjusting members are allowed to rotate; and
a link plate configured to connect the plurality of air flow direction adjusting members to one another such that the plurality of air flow direction adjusting members rotate in an interlocked manner, wherein

each of the plurality of air flow direction adjusting members includes
a rotation shaft attachment portion attached to a corresponding one of the attachment shafts,
a link plate engagement portion engaged with the link plate, and
an operation member attachment portion to which a manual operation member for manually adjusting orientation of the air flow direction adjusting members is attachable, and

the base member includes
a housing comprising a recess disposed at a location corresponding to one of the air flow direction adjusting members to which the manual operation member is attached, the recess configured to provide clearance for the manual operating member when the manual operating member is attached to the one of the plurality of air flow direction adjusting members and configured to house the manual operation member, and
an attachment-inhibiting portion that is located at a location corresponding to another one of the plurality of air flow direction adjusting members to which the manual operation member is not attached and that hinders attachment of the manual operation member.
