Looking at the operation of the present invention configured as described above are as follows.

First, when the air conditioner is operated, indoor air is sucked into the inside of the main body 50 through the left, right side, or front lower portion of the main body 50 to pass through the inside of the main body 50 to cool / heat. Alternatively, the purified liquid is discharged toward the front of the main body 50 through the front left, right or upper surface of the main body 50.

Hereinafter, the suction and cooling / heating / purification and discharge of the indoor air will be described in more detail.

As shown in FIG. 1, in the cooling / heating operation of the air conditioner, the left suction vane driving motor 93a is driven in a left inlet opening mode so that the left suction vane 93 is connected to the left side air intake port ( 51 is opened, and the right suction vane driving motor 103a is driven in the right inlet opening mode so that the right suction vane 103 opens the right side air inlet 52.

In addition, the motor 81 of the door driving mechanism 80 is driven in the door opening mode to rotate the pinion 82 counterclockwise, and the left rack 83f is formed. The left drive member 83 slides to the right, and the right drive member 84 on which the right rack 84f is formed slides to the left.

When the right side of the left rack 83f slides right, the front left outlet port 77 flows in between the front center of the upper panel 72 and the front cover 85 to open the front left air outlet 54. .

On the other hand, when the left side sliding of the right rack 84f, the front right outlet port 78 is introduced between the front center of the upper panel 72 and the front cover 85 so that the front right air outlet 55 To open.

In addition, the upper door motor 86a is driven in the upper air outlet opening mode so that the upper door 86 opens the upper air outlet 56.

When the blowing motor 151 is driven, indoor air is sucked into the main body 50 through the left side air inlet 51, the right side air inlet 52, and the front air inlet 53. do.

The indoor air sucked through the left side air inlet 51 passes through the left prefilter 94, and dust and the like are filtered out, and the indoor air sucked through the right side air intake 52 is the right prefilter 104. As it passes through, bulky dust is filtered out.

In addition, the indoor air sucked through the front air intake port 53 is dust filtered while passing through the lower prefilter 171, fine dust is filtered while passing through the hepa filter 172, and the nano filter ( 173) removes odor particles and bacteria in the air.

The indoor air purified as described above passes through the ionizing unit 175, the collecting unit 176, the orifice 156, and the fan housing 155 of the electrostatic precipitator 174 to the upper side of the fan housing 155. It is blown.

Air blown to the upper side of the fan housing 155 is cooled or heated by heat exchange with the refrigerant while passing through the heat exchanger 160.

A part of the indoor air cooled or heated as described above is blown to the upper front side of the main body 50 through the upper surface air discharge port 56, and most of the indoor air is discharged from the front left air outlet 54 and the front right air outlet 55. Blows toward the front side of the main body (50).

That is, since the indoor unit of the air conditioner is cold or warm air is blown toward the front from the front left and right of the main body 50, it is possible to quickly and evenly supply the cold or warm air to the user located in front of the indoor unit.

On the other hand, during the air cleaning operation of the air conditioner, the left suction vane driving motor 93a is driven in a left inlet inlet closing mode such that the left inlet vane 93 seals the left side air inlet 51, The right suction vane driving motor 103a is driven in a right inlet inlet closing mode such that the right inlet vane 103 seals the right side air inlet 52.

Then, the motor 81 of the door drive mechanism 80 is driven in the door closing mode, as shown in Figure 8 to rotate the pinion 82 in the clockwise direction, the left side of the left rack (83f) is formed The drive member 83 slides to the left, and the right drive member 84 on which the right rack 84f is formed slides to the right.

The front left outlet port 77 moves forwardly of the front left air outlet 54 between the front center of the upper panel 72 and the front cover 85 when the left side of the left rack 83f slides. To seal the front left air outlet 54.

The front right outlet door 78 moves forwardly of the front right air outlet 55 between the front center of the upper panel 72 and the front cover 85 when the right side rack 84f slides to the right. To seal the front right air outlet 55.

On the other hand, the upper door motor 86a is driven in the upper air outlet opening mode so that the upper door 86 opens the upper air outlet 56.

The high voltage generated by the high voltage generator 177 is applied to the ionizing unit 175 and the collecting unit 176, and the blower motor 151 is driven.

When the blower motor 151 is driven, indoor air is sucked into the main body 50 through the front air inlet 53.

The indoor air sucked through the front air intake port 53 is dust filtered while passing through the lower prefilter 171, fine dust is filtered while passing through the hepa filter 172, and the nano filter 173. While passing through, airborne odor particles and bacteria are removed.

As described above, the purified indoor air passes through the ionizing unit 175 and the collecting unit 176 of the electrostatic precipitator 174 to collect and ionize the dust in the air, and then the frying orifice 156 and the fan housing 155. ) Is sequentially blown to the upper side of the fan housing 155.

The air blown to the upper side of the fan housing 155 passes through the heat exchanger 160 without heat exchange, and then is concentratedly blown to the upper front side of the main body 50 through the upper surface air discharge port 56.

On the other hand, when the air conditioner stops operating, the left suction vane driving motor 93a is driven in a left inlet inlet closing mode such that the left inlet vane 93 seals the left side air inlet 51, The right suction vane driving motor 103a is driven in a right inlet inlet closing mode such that the right inlet vane 103 seals the right side air inlet 52.

Then, the motor 81 of the door driving mechanism 80 is driven in the same manner as the air cleaning operation, so that the front left side outlet port 77 seals the front left side air outlet port 54, and the front right side outlet port door (78) seals the front right air outlet (55).

In addition, the upper discharge port door motor 86a is driven in the upper air discharge port closed mode so that the upper discharge port door 86 seals the upper air discharge port 56.
