Through the magnetic force of the second magnetic member 3567 and the third magnetic member 3575, the gap between the cover plate 3570 and the air guide 3560 can be minimized, thereby suppressing the leakage of cold air. there is.

Hereinafter, an operation process of the air guide 3560 will be described with reference to FIGS. 30 to 32 .

Referring to FIG. 30 , when the indoor unit is in a stopped state, the fan housing assembly 3400 maintains a state accommodated in the accommodation space S1 .

Specifically, the cover plate 3570 is in a state of pushing the third locking part 3568 to the rear side, and the first locking part 3564 maintains a state in close contact with the rear wall 3522 .

Referring to FIG. 31 , when the fan housing assembly 3400 is advanced for the operation of the remote fan assembly 400 , the cover plate 3570 integrally disposed with the rear fan housing 3410 is advanced together.

In this embodiment, the advancement of the remote fan assembly 400 may be divided into two stages.

When the fan housing assembly 3400 first moves forward, the front end of the steering grill 3450 may be located in the door assembly 200 . Specifically, the front end of the steering grill 3450 may be disposed on the same line as the front discharge port 201 during the first forward movement.

During the first advance, the cover plate 3570 may advance to the second locking portion 3566 . During the first advance, the second magnetic member 3567 and the third magnetic member 3575 of the second locking part 3566 are coupled by magnetic force.

The length during the first advance is the same as the length between the second locking part 3566 and the third locking part 3568 .

During the first advance, the air guide 3560 and the cover plate 3570 are integrated by the coupling of the second magnetic member 3567 and the third magnetic member 3575 .

Referring to FIG. 32 , when the fan housing assembly 3400 moves forward a second time, the coupling by the magnetic force of the first magnetic member 3565 and the fourth magnetic member 3585 is released. In this embodiment, the second advanced state is defined as a projection state.

That is, the actuator 3470 advances the fan housing assembly 3400 by a second force greater than the magnetic force of the first magnetic member 3565 and the fourth magnetic member 3585, and thereby the first magnetic member 3565 ) and the fourth magnetic member 3585 are separated.

In the second advance, the first stopping part 3564 of the air guide 3560 moves to the guide stopper 3580 .

During the second advance, the first stopper 3564 interferes with the guide stopper 3580, and the second advance of the fan housing assembly 3400 is completed.

During the second advance, as shown in FIG. 4 , the front end 3452a of the steering housing 3452 protrudes forward than the front surface 200a of the door assembly 200 .

At the time of the first forward movement, air may be discharged into the room in a state in which the steering grill 3450 does not protrude outward, and the steering range of the steering grill 3450 may be limited.

Since the steering grill 3450 protrudes out of the front discharge port 201 during the second forward movement, the steering range of the steering grill 3450 can be utilized to the maximum.

Next, the steering assembly 3400 may be moved backward in the first forward state or in the second forward state into the receiving space S1 at once. Also, the steering assembly 3400 may move backward from the second forward state to the first forward state.

Since the air guide 3560 and the cover plate 3570 are integrated by the coupling of the second magnetic member 3567 and the third magnetic member 3575,

When the steering assembly 3400 moves backward, the air guide 3560 may move backward together with the steering assembly 3400 .

Moving backward from the second forward state to the first forward state is defined as the first backward movement. Moving backward from the first forward state to the stowed state is defined as the second backward movement.

In the first backward movement, the air guide 3560 and the cover plate 3570 are moved backward together in the state shown in FIG. 31 .

Next, during the second backward movement, the second magnetic member 3567 and the third magnetic member 3575 are separated by the driving force of the actuator 3470 . Since the air guide 3560 is supported by the rear wall 3522 during the first reversing, the second magnetic member 3567 and the third magnetic member 3575 may be separated during the second reversing. can When the second backward movement is completed, the state shown in FIG. 30 is the same.

As described above, although the air guide 3560 of the present invention has a structure that is relatively moved between the guide housing and the front fan housing 3430, the first magnetic member 3565, the second magnetic member 3567, and the third magnetic member The air guide 3560 may be disposed at an accurate position through the member 3575 and the fourth magnetic member 3585 .

When the first advance or the second advance, by positioning the air guide 3560 at an accurate position, it is possible to minimize the leakage of cold air.

In particular, since the second magnetic member 3567 and the third magnetic member 3575 are magnetically coupled, it is possible to suppress the air guide 3560 from shaking or deviated from its original position during the first advance.

Similarly, since the first magnetic member 3565 and the fourth magnetic member 3585 are magnetically coupled, the air guide 3560 is prevented from shaking or deviated from its original position when the fan housing assembly 3400 is accommodated. can be minimized

In the absence of the magnetic member, since the air guide 3560 freely moves relative to each other, the amount of cold air leakage may increase. In the absence of the magnetic member, since the air guide 3560 freely moves relative to each other, vibration is generated by the wind pressure of the discharged air, and thus operating noise may be generated.

Hereinafter, since the rest of the configuration is the same as that of the first embodiment, a detailed description thereof will be omitted.
