The heat exchanger 50 is mounted to the cabinet 10 and the front inner panel 20 to be inclinedly positioned between the front inner panel 20 and the cabinet 10.

The blower 60 is mounted to the cabinet 10 to be positioned below the heat exchanger 50.

The blower 60 has an open front surface and a discharge hole formed on an upper surface thereof, a fan housing 61 mounted in the cabinet, a fan rotatably positioned inside the fan housing, and the fan to rotate the fan. And a blower motor connected to the shaft, and an orifice 62 mounted to the front of the fan housing.

The front surface of the blower 60 is equipped with a photocatalyst plasma air purifier 70 for purifying the air sucked into the blower 60.

The photocatalyst plasma air purifier 70 ionizes dust in the air by discharging and irradiates light energy, an ion collecting unit for collecting dust ionized by the ionizing unit, and odor particles are collected and the ionizing unit is ionized. And a photocatalyst filter for decomposing odor particles collected by light energy irradiated from inside the unit, and a high voltage generator for applying a high voltage to the dust collecting filter.

Reference numeral 84 is a control box installed in the blower 60 is equipped with electrical components for controlling the operation of the indoor unit.

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

First, when the indoor unit of the air conditioner receives a cooling / heating operation command, the first inlet panel 4 is rotated by a motor to open the suction guide part 3, and the second and third parts are operated. Inlet panels 31 and 37 are rotated by a motor to open each of the air inlet ports 30a and 36a, and each of the first and second discharge port panels 24 and 25 is rotated by a motor to Each of the side air outlets 21 and 22 is opened, and the blower motor is driven to rotate the blower fan.

When the blowing fan is rotated, air outside the indoor unit of the air conditioner is sucked into the indoor unit of the air conditioner through the suction guide part 3 and the air suction ports 30a and 36a.

The air sucked through the suction guide 3 is guided to the upper side of the base 2 and then purified by passing through the first filter 6, the second filter 7, and the third filter 8. The air sucked through the air inlets 30a and 36a is purified while passing through the fourth and fifth filters 33 and 39.

The purified air as described above is pumped to the front of the blower 60, passes through the photocatalyst plasma air purifier 70, passes through the orifice 62 and the fan housing 61, the upper side of the blower 60 Is blown into.

Then, it is heated or cooled while passing through the heat exchanger 50, and is discharged to the side air outlets 21 and 22.

On the other hand, when the indoor unit of the air conditioner receives an operation command for purifying the air, the first intake port panel 4 is rotated by a motor to open the intake guide part 3, and the second and third intake ports. Each of the panels 31 and 37 are reversely rotated by a motor to seal each of the air intake ports 30a and 36a, and to open each of the first and second discharge port panels 24 and 25, The blower motor is driven to rotate the blower fan, and a high voltage is applied to the photocatalyst plasma air purifier 70.

When the blowing fan is rotated, air outside the indoor unit of the air conditioner is sucked into the indoor unit of the air conditioner through the suction guide part 3, and the sucked air is guided to the upper side of the base 2. After passing through the first filter (6), second filter (7) and third filter (8) in order to purify and then forwarded to the front of the blower (60) to pass through the photocatalyst plasma air purifier (70) do.

The air passing through the photocatalyst plasma air purifier 70 is ionized and collected by the dust in the air, and the odor particles are collected and purified again. Blown to the upper side of the), and after passing through the heat exchanger 50 is concentrated discharged to the outside of the indoor unit of the air conditioner through the side air outlet (21, 22).

Meanwhile, the indoor unit of the air conditioner disassembles the front panel 40, replaces the color panel 42 with a new color panel, and assembles the front panel 40. Easily changed.

In addition, when the first, second, third, fourth, fifth filter (6) (7) (8) (33) (39) is to be cleaned or replaced, the front panel (40) fixed by hanging is removed. The front part 20c of the front inner side panel 20 and the front lower side of the front part 20c are opened, and the said 1st, 2nd, 3rd, 4th, 5th filter (6) (7) (8) ( 33) and 39 are easily pulled out to the front side thereof, so that the first, second, third, fourth and fifth filters 6, 7, 8, 33 and 39 can be easily cleaned or replaced. .

The indoor unit of the air conditioner of the present invention is not limited to the above-described embodiment, and may be variously modified and implemented within the range permitted by the technical idea of the present invention.

As apparent from the above description, according to the indoor unit of the air conditioner of the present invention, since the front panel is fixed to the front inner panel, the member to be fixed is not visible from the outside, so that the overall aesthetics can be improved.
