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

First, as shown in FIGS. 1, 2, and 6, when the separate air conditioner is cooled or heated in a state where the filter unit 70 is mounted on the top surface of the front frame 54, the outdoor unit ( The compressor of 120 is driven, the front panel rotating motor 68 is driven in the open mode, the louver rotating motor 76 is driven in the open mode, and the blower motor 92 of the blower 90 is driven. ) Is driven.

When the compressor of the outdoor unit 120 is driven, refrigerant is circulated in the compressor, the outdoor heat exchanger, the expansion mechanism, and the indoor heat exchanger, and the indoor heat exchanger 96 deprives the surrounding heat or releases heat to the surroundings. Air to cool / heat.

On the other hand, when the front panel rotating motor 68 is driven in the open mode, the pinion 67 is rotated to advance the rack 69, the front panel 60 is shown in Figures 1 and 6 As shown in FIG. 3, the air inlet is formed between the front surface of the front frame 54 and the indoor unit 51 of the separate air conditioner. Intake of the indoor air through the intake port 55 becomes possible.

When the louver rotating motor 76 is driven in the open mode, the louver 75 opens the suction hole 71a of the filter case 71 as illustrated in FIGS. 1 and 6.

Then, when the blower motor 92 of the blower 90 is driven, the blower fan 94 is rotated, and the indoor air at the front, upper, and rear of the indoor unit 51 of the separate air conditioner is the front surface. The air intake port 55, the upper air intake port 56, and the rear air intake port 53 are sucked in.

As shown in FIG. 6, the indoor air sucked into the front air intake port 55 passes through the prefilter 63 mounted on the front side of the front frame 54, and foreign matter such as dust is transferred to the prefilter. (63).

The indoor air, through which the foreign matter is filtered while passing through the pre-filter 63, passes through the electric dust collector 62 mounted on the front side of the front frame 54, and small dust that is not filtered by the pre-filter 63. Ionize and collect foreign substances.

The purified indoor air is cooled / heated by the refrigerant while passing through the vertical part 97 or the first inclined part 98 of the indoor heat exchanger 96.

Meanwhile, as shown in FIG. 6, indoor air sucked into the upper surface air intake port 56 is purified by the filter 72 while passing through the filter unit 70, and then, the interior of the indoor heat exchanger 96 is removed. Cooling / heating is performed by the refrigerant while passing through the first inclined portion 98 or the second inclined portion 99.

The purifying action of the filter unit 70 will be described in more detail. The indoor air sucked into the upper surface air suction port 56 passes through the suction hole 71a of the filter case 71 so that It is sucked into the inside, while passing through the pre-filter 72a, the nano-copper filter 72b, the nano-silver filter 72c, and the electrostatic precipitator 72d, foreign matters such as dust are filtered, antibacterial or sterilized, and small dust Foreign matter such as ionization is collected by ionization, and flows into the space between the chassis 52 and the front frame 54 through the communication hole 71b.

On the other hand, the indoor air sucked into the rear air intake port 53 extends to the front of the rear air intake port 53 among the filters 72a, 72b, 73c, and 74d, as shown in FIG. It is purified by the bent filter 72a and cooled / heated by the refrigerant while passing through the second inclined portion 99 of the indoor heat exchanger 96.

The indoor air cooled / heated as described above is guided by the louver 104 and the vane 106 of the discharge grill 108 after passing through the blower fan 94 to the room through the air discharge port 57. Discharged.

On the other hand, when the separate type air conditioner is cleanly operated while the filter unit 70 is mounted on the upper surface of the front frame 54, the compressor of the outdoor unit is not driven, and the louver rotating motor 76 is in an open mode.

Subsequently, the louver 104 and the vane 106 of the discharge grill 108 are guided and discharged into the room through the air discharge port 57.

On the other hand, the front panel rotation motor 68 may be driven in the open mode as the louver rotation motor 76 during the clean operation of the separate type air conditioner.

That is, when the front panel rotating motor 68 is driven in the open mode during the clean operation as described above, indoor air is also sucked through the front air inlet 55, and the sucked indoor air is the front frame 54. After being purified by the pre-filter 63 and the electrostatic precipitator 62 installed on the front side of the discharge through the air discharge port 57 with the air passing through the filter unit 70 is discharged into the room.

On the other hand, when the separate type air conditioner is deactivated, the compressor of the outdoor unit 120 is stopped driving, the front panel rotating motor 68 is driven in a sealed mode, and the louver rotating motor 76 is sealed. Mode is driven, and the blower motor 92 of the blower 90 is stopped.

When the front panel pivoting motor 68 is driven in the closed mode, the pinion 67 is rotated in reverse to reverse the rack 69, the front panel 60 as shown in FIG. It rotates forward about the first link 65 to block the front of the front air inlet 55 of the front frame 54.

When the louver rotating motor 76 is driven in the closed mode, the louver 75 seals the suction hole 71a of the filter case 71 as shown in FIG. 2.

3, 4, and 7, when the separate air conditioner is operated while the suction grill 80 is mounted on the top surface of the front frame 54, the compressor of the outdoor unit 120 is driven. The front panel rotating motor 68 is driven in the open mode, and the blowing motor 92 of the blower 90 is driven.

An operation according to the operation of the compressor of the outdoor unit 120, an operation according to the open mode driving of the front panel rotating motor 68, an operation of suctioning indoor air through the front air intake port 55, and The cooling / heating action by the heat exchanger 96 and the discharge operation of the indoor air through the air discharge port 57 are the same as when the filter unit 70 is mounted on the upper surface of the front frame 54. Is omitted.

As shown in FIG. 7, the indoor air sucked into the upper surface air intake port 56 passes through the suction grille 80 and the first inclined portion 98 or the second inclined portion of the indoor heat exchanger 96. While passing through 99, it is cooled / heated by the refrigerant.

As shown in FIG. 7, the indoor air sucked into the rear air intake port 53 passes through the rear air intake port 53 and passes through the second inclined portion 99 of the indoor heat exchanger 96. By cooling / heating.
