 The air sucked through the right air inlet 5 passes through the right filter 13, and foreign substances such as dust are filtered out and flows into the inner space of the filter 10.

The air sucked through the rear air suction port 6 passes through the rear filter 11, and foreign matters such as dust are filtered out, and the dust not passed through the rear filter 11 while passing through the plasma filter 16. And odor particles and the like are ionized and collected in the plasma filter 16, and the purified air passing through the plasma filter 16 flows into the inner space of the filter 10.

As described above, the air flowed into the inner space of the filter 10 flows up and down in the inner space of the filter 10.

The air flowed upward is passed through the upper filter 14, and the foreign matter such as dust is filtered again and then purified. Then, the upper gradient heat exchanger 84 and the upper vertical heat exchanger 82 of the upper heat exchanger 80 are cleaned. It is heated or cooled by, and is discharged to the upper portion of the main body 1 through the upper blowing fan 42 and the upper surface air discharge port (2).

In addition, the air flowing downward is purified by being filtered again while foreign substances such as dust pass through the lower filter 15, and the lower inclined heat exchanger 94 and the lower vertical heat exchanger 92 of the lower heat exchanger 80. Is heated or cooled, and is discharged to the lower part of the main body 1 through the lower blower fan 62 and the lower surface air discharge port (3).

Meanwhile, since the indoor unit of the air conditioner needs to be cleaned or replaced regularly because foreign matters are accumulated in the filter 10 and the plasma filter 16, the filter 10 or the plasma filter 16 is to be cleaned or replaced. When the filter 10 is pulled sideways through any one of the left and right air inlets 4 and 5, the filter 10 is guided to the filter guide 95 while the plasma filter is pulled out. Together with 16, the side surface of the main body 1 is pulled out.

In addition, when the user inserts a hand in the inner space of the filter 10 and pulls the plasma filter 16 forward while flexing the hook portion 17B elastically, the plasma filter 16 is placed in the settled portion. It is separated forward at 17A.

When the plasma filter 16 is mounted on the filter 10, the plasma filter 16 is pushed into the settled portion 17A while the plasma filter 16 is inserted from the front of the filter 10 to the inside. The hook portion 17B is elastically bent to help the plasma filter 16 to be settled by the settling portion 17B, and when the plasma filter 16 is settled deeply in the settled portion 17A, the hook portion 17B causes the plasma filter 16 to be caught in the front while being elastically restored to its original shape, and the plasma filter 16 is mounted to the front of the filter 10, in particular the rear filter 11, without any removal. .

On the other hand, if the filter 10 is positioned next to the side of the main body 1 and inserted into the side air inlet in the opposite direction as the filter 10 withdrawal, the filter 10 is the filter guide ( Guided to 95 and slides into the main body 1 together with the plasma filter 16, and is disposed between the left air intake port 4 and the right air intake port (5).

On the other hand, the present invention is not limited to the above embodiment, it is also possible to be provided with a front filter between the front end of the left filter and the right filter instead of the rear filter, various implementations are possible within the technical scope of the present invention. Of course.

Since the indoor unit of the air conditioner of the present invention configured as described above is sucked with indoor air through the side air intake port and the rear air intake port, the structure of the front part can be simplified and the overall thickness can be reduced and the advantages can be improved. There is this.

In addition, the indoor unit of the air conditioner of the present invention has a filter disposed in the side of the side air intake port and the front of the rear air intake port, there is an advantage that can efficiently clean the air sucked from the side and rear of the indoor unit.

In addition, the indoor unit of the air conditioner of the present invention, the filter is opposed to the rear air inlet, the left filter bent opposite to the left air inlet from the left side of the rear filter, and the right side air inlet from the right side of the rear filter Including the right filter is bent, there is an advantage that can more efficiently purify the air sucked in the three directions of the indoor unit.

In addition, the indoor unit of the air conditioner of the present invention further comprises an upper filter, the filter bent at the top of at least one of the rear filter and the side filter, and a lower filter bent at the bottom of at least one of the rear filter and the side filter. Thus, there is an advantage that the air purified from the rear filter and the side filter can be purified again with a simple structure.

 In addition, the indoor unit of the air conditioner of the present invention is provided with a filter guide that the filter slides in the left and right directions, detachable, there is an advantage that the filter can be easily attached and detached.

In addition, since the indoor unit of the air conditioner of the present invention has a size in which the filter enters from side to side through the side air intake port, a separate opening is not required for access of the filter, and the structure of the main body is simple.

In addition, the indoor unit of the air conditioner of the present invention further comprises a plasma filter disposed in the space formed by the filter, it is possible to minimize the thickness of the indoor unit of the air conditioner than when the plasma filter is installed in the front portion of the main body And there is an advantage that can be made as slim as possible.

In addition, the indoor unit of the air conditioner of the present invention has a plasma filter holder in which the plasma filter is mounted on the filter, and thus, the structure is simpler and less expensive than the case in which a separate case in which the plasma filter is mounted is provided.

 In addition, the indoor unit of the air conditioner of the present invention is formed with an upper air outlet on the upper surface of the main body, and an air outlet is formed on the lower surface of the main body, and an upper blower fan is rotatably disposed below the upper air outlet. The lower blower fan is rotatably disposed on the upper side of the air discharge port, and the air is distributed and discharged in the upper and lower directions of the main body, thereby preventing the user from feeling uncomfortable when the air is discharged forward. There is an advantage to this.

In addition, the indoor unit of the air conditioner of the present invention includes an upper heat exchanger installed to be located above the filter so that the air passing through the filter is exchanged before the air is sucked into the upper blower fan; It further comprises a lower heat exchanger installed to be positioned below the filter so that the air passing through the filter is heat exchanged before being sucked into the lower blower fan, there is an advantage that can be slimmer if the filter is disposed in front of the heat exchanger.
