A door cover assembly closes a front discharge port when a fan assembly is not operated and allows the door cover assembly to move out of the front discharge port, and the front discharge port opens when the fan assembly is operated, and a fan housing assembly can protrude out of a door assembly by means of an actuator when the front discharge port is opened.

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.

An air conditioner may provide a fan housing assembly that moves in the front-rear direction by the operation of an actuator, and the fan housing assembly moves so as to pass through a front outlet arranged on a door assembly to be in a projected state, and the front end of the fan housing assembly protrudes further to the front than the front surface of the door assembly; and through the projected state, may provide conditioned air by a direct air flow to a long-distance target region. The configuration may enable the minimization of interference between the discharged air and the door assembly, and the minimization of flow loss of the discharged air since, when the fan housing assembly is in the projected state, a steering grill is in a state of protruding to the outside of the door assembly by passing through the front outlet.

Disclosed is an indoor unit for an air conditioner. The indoor unit for the air conditioner according to the present invention includes: a cabinet assembly forming an external appearance of the indoor unit and having an air suction port formed in a rear of the cabinet assembly; a filter module disposed at the air suction port to filter dust contained in air being introduced through the air suction port; a filter cleaner configured to move upward and downward in a rear of the filter module to remove foreign substances stuck in the filter module; a guide rail vertically disposed on one side of the filter module and configured to guide upward and downward movement of the filter cleaner, wherein the filter cleaner comprises: a mobile gear configured to rotate while engaged with the guide rail to move the filter cleaner upward and downward with respect to the filter module, a gear motor configured to rotate the mobile gear, an agitator configured to rotate in friction with the filter module, a dust container disposed downward of the agitator and collecting foreign substances separated from the filter module due to the rotation of the agitator, and a guide roller bringing the filter cleaner into close contact with the filter module so that part of the agitator rotates while in contact with the filter module.
