Abstract

Provided is an indoor unit of an air conditioner, and the indoor unit includes: a case installed indoors and having an outlet formed in a front or bottom thereof; and a vane module disposed at the case and guiding a flow direction of air discharged from the outlet, and the vane module includes: a first vane disposed in the outlet and rotatably installed on a forward side of a discharge direction of discharged air; a second vane disposed in the outlet and rotatably installed; two motor coupling parts disposed at both ends of the first vane and the second vane, respectively, wherein two motors each have at least a portion of which is exposed to the outlet; a vane motor assembled with at least one of the two motor coupling parts and providing a driving force; a drive link assembled to be rotatable rotatably to the motor coupling part, rotated by the driving force of the vane motor, and transmitting the driving force to the first vane and the second vane; a first vane link assembled to be relatively rotatable with the drive link and the motor coupling part on a forward side of the drive link to thereby rotate the first vane; and a second vane link assembled to be relatively rotatable with the drive link and the motor coupling part on a forward side of the drive link to thereby rotate the second vane, and the first vane link and the second vane link are assembled in a line with the drive link on a forward side of the drive link. Accordingly, a size of the vane itself may be maximized by minimizing a space occupied by a drive module.

Dependent claims

An indoor unit of an air conditioner, the indoor unit comprising:

a case having an outlet;
and
a vane module that is disposed at the case and guides a flow direction of air discharged from the outlet, wherein the vane module comprises:
a first vane rotatably installed in the outlet;
a second vane rotatably installed in the outlet;
two motor coupling parts disposed at both ends of the first vane and the second vane, respectively, wherein at least a portion of each of the two motor coupling parts is exposed to the outlet;
a vane motor that is assembled with at least one of the two motor coupling parts and provides a drive force;
a drive link that is assembled to be rotatable with respect to the motor coupling part, rotated by the driving drive force of the vane motor, and transmit the drive force to the first vane and the second vane;
a first vane link assembled to be relatively rotatable with respect to the drive link and the motor coupling part on a forward side of the drive link to thereby rotate the first vane;
and
a second vane link assembled to be relatively rotatable with respect to the drive link and the motor coupling part on the forward side of the drive link to thereby rotate the second vane, wherein the first vane link and the second vane link are assembled in a line with the drive link on the forward side of the drive link, wherein the motor coupling part comprises two guide holes that indicate a path of rotation of the drive link, the drive link passing through the two guide holes and being assembled with the motor coupling part, wherein the two guide holes are formed in the motor coupling part with a drive link coupling hole as a center, and wherein the two guide holes are each formed in an arc shape along a circumference of a circle at a predetermined distance from the drive link coupling hole as the center.
