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

9 is a flowchart illustrating an embodiment of a filter control method of an air conditioner according to the present invention.

First, when a command of a cooling operation / heating operation is input through the input unit 96, the controller 97 checks the input command.

When the cooling operation is input, the controller 97 controls the second filter motor 66 to the purification mode as shown in FIG. 4 (S1).

In the purging mode of the second filter motor 66, the second filter 62 is rotated together with the second filter holder 64 and is positioned at a position perpendicular to the air flow of the second combined air inlet 4. Is located.

In addition, when a cooling operation is input, the controller 97 controls the first filter motor 56 to the avoidance (non-purification) mode as shown in FIG. 4.

In the unpurified mode of the first filter motor 56, the first filter 52 is positioned alongside the air flow of the first combined air inlet 2 together with the first filter holder 54.

In addition, the controller 97 drives the upper motor 76 in a state where the first filter 52 and the second filter 62 are positioned as described above during the cooling operation.

When the upper motor 76 is driven, the upper blowing fan 74 is rotated in one of the clockwise and counterclockwise directions (counterclockwise direction shown in FIG. 4), and the upper blowing fan 74 is rotated. The lower air is pumped upward by the upper blowing fan 74.

At this time, the indoor air (A) is collected in the lower portion of the air conditioner by the negative pressure formed by the rotation of the upper blower fan 74, and is sucked upward through the second combined air inlet (4) Foreign matter such as dust is filtered out by the second filter 62 and is sucked between the main chassis 12 and the front panel assembly 20.

The sucked air A is cooled by being deprived of heat by the refrigerant passing through the heat exchanger 18 while passing through the blowing passage P, and then blown upward through the upper blowing fan 74.

The cold air A ′ blown upwards passes quickly through the first dual purpose air inlet 2 because the first filter 52 is positioned in parallel with the air flow of the first dual air inlet 2. Then, while the wind direction is adjusted by the first vane 36, as shown in Figure 1 and 4, it is discharged to the front upper side of the air conditioner.

The cold air A ′ discharged to the front upper side of the air conditioner is spread like a shower while spreading widely in the upper part of the room, and the room is cooled down evenly to a part far from the air conditioner.

On the other hand, when the heating operation is input, the control unit 97 controls the first filter motor 56 in the purification mode as shown in FIG. 5 (S3) (S4).

In the purifying mode of the first filter motor 56, the first filter 52 is rotated together with the first filter holder 54 and is positioned at a position perpendicular to the air flow of the first combined air inlet 2. Is located.

In addition, when the heating operation is input, the controller 97 controls the second filter motor 66 in the non-purification mode, as shown in FIG. 5.

In an unpurified mode of the second filter motor 66, the second filter 62 is positioned alongside the air flow of the second combined air inlet 4 together with the second filter holder 64.

 In addition, the control unit 97 drives the lower motor 86 in a state where the first filter 52 and the second filter 62 are positioned as described above during the heating operation.

When the lower motor 86 is driven, the lower blower fan 84 is rotated in the other direction (clockwise direction shown in FIG. 5) in a clockwise direction and a counterclockwise direction, and pumps the air above the lower side. .

At this time, a negative pressure is formed on the upper portion of the air conditioner 1 by the rotation of the lower blower fan 84, and the indoor air B is sucked downward through the first combined air inlet 2. While the foreign matter such as dust is filtered by the first filter 52, and then is sucked between the main chassis 12 and the front panel assembly 20.

The sucked air B is heated while depriving heat of the refrigerant passing through the heat exchanger 18 while passing through the blowing passage P, and is blown downward through the lower blowing fan 84.

The warmer B ′ blown downward is rapidly passed through the second dual purpose air inlet 4 since the second filter 62 is positioned in parallel with the air flow of the second dual air inlet 4. Then, while the wind direction is adjusted by the second vane 46, as shown in Figure 2 and 5, it is discharged to the front lower side of the air conditioner.

The warmth B ′ discharged to the front lower side of the air conditioner is widened to the lower part of the room and then raised, and the room is heated evenly to a part far from the air conditioner.

On the other hand, the air conditioner and the filter control method according to the present invention is formed on the left and right of the main body 10, the first and second combined air inlet (1, 2), respectively, and the cooling operation blower 72 and Of course, the heating operation blower 82 is applicable to the case in which it is installed on the inside left and right of the body 10, and of course, various implementations are possible within the technical scope of the present invention.

The air conditioner of the present invention configured as described above has a plurality of combined air inlets and outlets through which air is sucked or discharged in the main body, thereby realizing optimum air conditioning suitable for the characteristics of cooling operation and heating operation, respectively. Filters for purifying the air sucked into the air is provided, and a plurality of filters are selectively positioned at the combined air entrance and exit according to the cooling operation and the heating operation, there is an advantage that can minimize the decrease in the blowing capacity.

In addition, the filter control method of the air conditioner of the present invention, in the heating operation, while placing the first filter orthogonal to the air flow of the first combined air inlet, the second filter to the air flow of the second combined air inlet Side-by-side, and in a cooling operation, the second filter is positioned orthogonal to the air flow of the second combined air inlet, and the first filter is placed side by side to the air flow, thereby purifying and blowing air conditioners. There is a high performance advantage.
