Indoor unit of an air conditioner
A front end of a steering grill from which air is discharged protrudes further than the front surface of a door assembly, and the steering grill is steered by a steering assembly, and thus conditioned air may be provided by a directed air movement to a long-distance target region, and since the front end of the steering grill protrudes further than the front surface of the door assembly, the occurrence of flow resistance as a result of a cabinet assembly or the door assembly interfering with the discharged air may be minimized, and the direction of the steering grill may be instantly changed, by means of steering, from any one direction to another among up, down, left, right, upper left, lower left, upper right, or lower right.
1. An air conditioner comprising:
a casing having a suction inlet and a discharge outlet defined therein communicating an inner space of the casing with an indoor space;
a grille configured to adjust a discharge direction of air discharged to the discharge outlet;
a fan housing located in rear of the grille;
a steering assembly disposed between the fan housing and the grille and configured to tilt the grille,
wherein the steering assembly includes:
a steering body;
a steering actuator coupled to the steering body;
a moving rack movably coupled to the steering body and movable along the steering body under an operation of the steering actuator; and
an adjust assembly coupled to each of the moving rack and the grille so as to be rotatable relative thereto,
wherein the adjust assembly is configured to pushes or pull the grille while rotating relative to at least one of the moving rack or the grille under movement of the moving rack.
2. The air conditioner of claim 1 , wherein the steering body is fixed to a side of the front fan housing.
3. The air conditioner of claim 1 , wherein the steering body is fixed to a side of the grille.
4. The air conditioner of claim 1 , further comprising:
a rack guide disposed on the steering body, wherein the moving rack is movably coupled to the rack guide, wherein the rack guide guides a moving direction of the moving rack; and
a steering gear coupled to the steering actuator, and engaged with the moving rack, wherein the steering gear provides a driving force to the moving rack based on an operation of the steering actuator.
5. The air conditioner of claim 4 , wherein the rack guide is formed as a slit extending through the steering body, wherein the moving rack is inserted into the rack guide formed as the slit.
6. The air conditioner of claim 4 , wherein the moving rack includes:
a moving rack body;
a moving rack gear disposed on the moving rack body and extending in a longitudinal direction of the moving rack body;
a guide block disposed on the moving rack body and coupled to the rack guide so as to be movable relative to the rack guide; and
a moving rack coupler disposed on the moving rack body and coupled to a rear structure of the adjust assembly.
7. The air conditioner of claim 6 , wherein while the guide block has been inserted into the rack guide, the guide block is movable,
wherein the guide block and the rack guide are engaged with each other such that the guide block is prevented from moving in a direction other than the moving direction of the moving rack.
8. The air conditioner of claim 7 , wherein the guide block includes a guide protrusion extending in the moving direction of the moving rack,
wherein the rack guide has a guide groove defined therein in a corresponding manner to the guide protrusion.
9. The air conditioner of claim 1 , wherein the adjust assembly is configured to adjust at least one of a distance or an angle between the grille and the moving rack when the moving rack moves.
