(S3, S4)

At this time, the lower vane motor 150 rotates the lower vane 52 so that the lower air intake guide 50a is opened, and the left vane motor 160 rotates the left air inlet 70a and the left air. The left vane 76 is reversely rotated to close the discharge port 72b, and the right vane motor 170 moves the left vane 76 to seal the right air inlet 70b and the right air outlet 72c. The upper vane motor 180 rotates the upper vane 75 to open the upper air outlet 70a.

That is, as shown in Figure 4, the indoor unit of the air conditioner, the air is sucked to one side and the air is discharged to one side, the control unit 200 drives the blower 90 and the The compressor and the electrostatic precipitators 120 and 122 are stopped.

The indoor air is sucked through the lower air suction guide part 50a into the lower part of the indoor unit of the air conditioner and is purified while passing through the lower air purification filter.

That is, the air sucked through the lower air intake guide 50a passes through the lower air filter 112 and is filtered with a relatively large foreign material, while passing through the lower hepa filter 110 with fine foreign matter. Dehumidified and purified.

The purified air as described above is blown around the heat exchanger 100 through the blower 90, blown to the upper side between the front cabinet 70 and the rear cabinet 60, and then the upper surface discharge port 72a. It is discharged to the room through).

Meanwhile, as shown in FIGS. 9 and 10, when the indoor unit of the air conditioner receives an operation stop command of the indoor unit of the air conditioner through the driving operation unit 190, the controller 200 controls the lower side. A sealed signal is output to each of the vane motor 150, the left vane motor 160, the right vane motor 170, and the top vane motor 180. (S5, S6)                     

At this time, the lower vane motor 150 reversely rotates the lower vane 52 so that the lower air intake guide 50a is sealed, and the left vane motor 160 is left of the left air inlet 70a and the left. The left vane 76 is reversely rotated so that the air outlet 72b is sealed, and the right vane motor 170 has the left vane 76 so that the right air inlet 70b and the right air outlet 72c are sealed. Reverse the rotation, and the upper vane motor 180 reversely rotates the upper vane 75 to seal the upper air outlet 72a.

That is, the indoor unit of the air conditioner, as shown in Figure 2, the lower air inlet guide 50a, the left air inlet 70a, the left air outlet 72b, the right air inlet 70b and the right air Penetration of foreign matter such as dust through the discharge port 72c and the upper surface air discharge port 72a is prevented.

The controller 190 stops driving the blower 90 and stops the compressor and the electrostatic precipitators 120 and 122.

The indoor unit of the air conditioner according to the present invention configured as described above has a lower air intake guide portion formed in the base, a rear cabinet is disposed above the rear portion of the base, and left and right air intake ports above the front portion of the base. And a front cabinet in which left and right air outlets are formed, and a lower suction vane for opening and closing the lower air suction guide part is installed in the base to prevent foreign substances such as dust through the lower air suction guide part. And, there is an advantage that can prevent internal contamination by foreign matters such as dust.

The indoor unit of the air conditioner may include left and right vanes arranged to open and close the left and right air inlets and the left and right air outlets, and may open and close the left air inlet and the left air outlet. And, the right air inlet and the right air outlet can be opened and closed together, there is an advantage that can prevent the infiltration of foreign matter, such as dust through the left, right air inlet and left, right air outlet.

In addition, the indoor unit of the air conditioner includes a top air discharge port formed on the upper surface of the front cabinet, it is possible to discharge the air / cooled or purified air above the air conditioner indoor unit more efficient three-dimensional cooling / The heating can be made, the upper surface vane is disposed to open and close the upper air outlet, there is an advantage that can prevent the infiltration of foreign matter, such as dust through the upper air outlet.

In addition, the indoor unit of the air conditioner further comprises a lower air purification filter to purify the air sucked into the lower air intake guide, there is an advantage that the air purification performance is improved.

In addition, in the indoor unit operation method of the air conditioner, air is sucked to three sides during cooling or heating operation, and then discharged to three sides for more efficient three-dimensional cooling / heating. After the discharge to one side there is an advantage that more intensive air purification can be performed.

In addition, the indoor unit operation method of the air conditioner seals the lower air inlet guide and the upper air outlet when the operation stops, and also seals the left and right air inlets and the left and right air outlets so that foreign matters such as dust through the air inlet. By preventing the penetration of the indoor unit of the air conditioner to prevent pollution, there is an advantage to create a more comfortable indoor environment when re-operation.
