The link means shown in FIG. 8 includes a first link 65c hinged to the front frame 54 and a second link 66c hinged to the front panel 60. , The two links 65c and 66c are formed to allow slide movement.

Here, the first and second links 65c and 66c are configured to be inserted into the second link 66c by sliding the first link 65c into the second link 66c as shown in FIG. 9. do.

Looking at the operation of the link means here.

First, when the motor 68 is driven and the pinion 67 is rotated, the rack 69 is moved forward or rearward, and the front panel 60 is also moved forward or backward by the movement of the rack 69. Is moved backwards. At this time, the front panel 60 is fixed to the lower side by the link means, the front panel 60 is a hinge shaft provided on the upper end of the second link (66c) and the lower end of the first link (65c) It is rotated about 65d and 66d.

Next, when the user removes the top of the front panel 60 to replace the pre-filter 63 in the indoor unit 50 or to perform cleaning, the user is the rack 69 and pinion ( After removing the engagement of 67, the front panel 60 is inclined upward to slide the second link 66c to extend the lengths of the first and second links 65c and 66c.

Then, the front end of the front frame 54 may be opened by rotating the upper end of the front panel 60 formed at the free end counterclockwise as shown in FIG. 10.

Looking at the operation of the front panel according to the present invention configured as described above are as follows.

First, 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 takes heat from the surroundings or heats the surroundings. Release to cool / heat the surrounding air.

3 and 9, when the front panel rotating motor 68 is driven in the open mode to drive the air conditioner, the pinion 67 is rotated by the motor 68 The rack 69 is advanced and the front panel 60 is rotated forward by the second link 66 about the first link 65 to open the front air inlet 55.

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 shown in FIGS. 3 and 5.

In addition, when the blower motor 92 of the blower 90 is driven, the blower fan 94 is rotated, and the indoor air at the front side, the upper side, and the rear side of the indoor unit 50 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. 3, the indoor air sucked into the front air inlet 55 passes through the pre-filter 63 mounted on the front side of the front frame 54, and foreign matters such as dust are transferred to the pre-filter ( 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, the 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 first inclined portion 98 or the first inclined portion of the indoor heat exchanger 96. 2 is cooled / heated by the refrigerant while passing through the inclined portion 99.

The purifying action of the filter unit 70 will be described in more detail. As shown in FIG. 5, the indoor air sucked into the upper air intake port 56 passes through the suction hole 71a of the filter case 71. The foreign material such as dust is filtered while being sucked into the inside of the filter case 71 and sequentially passing through the pre-filter 72a, the nano-copper filter 72b, the nano-silver filter 72c, and the electrostatic precipitator 72d. Antibacterial or sterilized, foreign matters such as small dust are ionized and collected, 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 is purified by the filter 72a extending and bent in front of the rear air intake port 53 among the filters 72a, 72b, 73c, and 74d. 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. The air blower motor 92 of the blower 90 is driven.

When the louver rotating motor 76 is driven in the open mode and the blowing motor 92 is driven, the indoor air that is above the indoor unit of the separate air conditioner is cooled or heated by the separate air conditioner. As shown in the drawing, it is purified while passing through the filter unit 70, sucked into the indoor unit of the separate air conditioner, passes through the indoor heat exchanger 96 without heat exchange, and passes through the blower fan 94. 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 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 closed mode, and the louver rotating motor 76 is Driven in the closed mode, the blower motor 92 of the blower 90 is stopped driving.
