The present invention relates to an indoor unit of an air conditioner, and more particularly, to an indoor unit of an air conditioner capable of purifying air sucked to a base side.

In general, an air conditioner is used to cool or heat a room or purify the air by using a refrigeration cycle of a refrigerant consisting of a compressor, a condenser, an expansion mechanism, and an evaporator to create a more comfortable indoor environment for a user. .

The separate type and the integrated type are functionally the same, but the separate type connects the indoor unit and the outdoor unit separated by the refrigerant pipes by installing the cooling / heating unit in the indoor unit and the heat radiating / cooling and compression unit in the outdoor unit, and the integrated type by cooling heat dissipation. Integrate the function of the hole in the wall of the house or hang the device on the window is installed directly.

6 to 9, the indoor unit of the conventional split type air conditioner includes a base 101, a cabinet 102 disposed longitudinally longer on an upper side of the base 101 and an open front surface thereof, It is coupled to the front surface of the cabinet 102, the front air outlet 104a and the upper side air outlets 104b and 104c are formed on both sides, the air inlet 104d (104e) is formed on both sides below, respectively It includes a front panel 104 formed, a blower 120 provided in the lower portion between the cabinet 102 and the front panel 104, and a heat exchanger 130 provided on the upper side of the blower 120.

On the other hand, the front panel 104 is installed in the front and rear drive panel 110 in the front and rear of the front panel 104 so as to open and close the air discharge port (104a), the vertical drive panel 110 In order to eliminate the step between the front panel 104 and the up and down drive panel 110 when the rise of the front and rear drive panel 112 is installed on the front of the front panel 104 to be retracted, the side air outlet 104b Left and right vanes 114 and 116 are provided on both sides of the front panel 104 so as to open and close the front and back sides 104c and to control the wind direction of the air discharged through the side air outlets 104b and 104c.

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 an operation command for cooling / heating, the first intake port panel 4 opens the air intake guide part 3, and the second and third intake panel 51. 57 opens each of the air inlets 50a and 56a, and each of the first and second outlet panels 43 and 44 opens each of the side air outlets 41 and 42. The third discharge port panel 46 opens each of the upper air discharge ports 45, and the blower motor of the blower 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 air suction guide 3 and the air intake ports 50a and 56a.

The air sucked through the air intake guide 3 is guided to the upper side of the base 2, and then passes through the first filter 6, the second filter 10, and the third filter 20. Is purified.

Hereinafter, the purifying action of the air guided to the upper side of the base 2 will be described in more detail.

As the air guided to the upper side of the base 2 passes through the first filter 6, large dust in the air is filtered, and fine dust is caught while passing through the HEPA filter 14 of the second filter 10. And odor particles and fine dust are adsorbed while passing through the nano carbon filters 15 and 16 of the second filter 10, and the nano copper filter 24 and the nano silver filter of the third filter 30. Antibacterial / deodorant while passing through 26).

On the other hand, the air sucked through the air inlets 50a and 56a passes through the fourth and fifth filters 52 and 58 to filter large dust in the air.

The purified air is pumped to the front of the blower is passed through the photocatalyst plasma air purifier 70, and is blown through the orifice and the fan housing to the upper side of the blower, heating or cooling while passing through the heat exchanger After the three-dimensional discharge through the side air discharge port 41, 42 and the upper surface discharge port 43.

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 opens the air intake guide 3, and the second and third intake panel 51 57 seals each of the air inlets 50a and 56a, and each of the first and second outlet ports 43 and 44 seals each of the side air outlets 41 and 42. The third discharge port panel 46 opens each of the upper air discharge ports 45, 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 air suction guide part 3, and the sucked air is moved upward of the base 2. After being guided, the first filter 6, the second filter 10, and the third filter 20 are sequentially purified.

The air purified by the first filter 6, the second filter 10, and the third filter 20 is pumped to the front of the blower and passes through the photocatalyst plasma air purifier 70.

The air passing through the photocatalyst plasma air purifier 70 is ionized and collected in the air, and odor particles are collected and purified, and are blown through the orifice and the fan housing to the upper side of the blower, and the heat exchanger After passing through the upper surface discharge port 45 is concentrated discharged to the outside of the indoor unit of the air conditioner.

On the other hand, when the first, second, third, fourth, fifth filter 6, 10, 20, 52, 58 is to be cleaned or replaced, the front panel 60 is rotated forward, The front of the lower side of the front inner panel 40 is opened, and the first, second, third, fourth, and fifth filters 6, 10, 20, 52, and 58 are easily drawn out to the front side thereof. The first, second, third, fourth and fifth filters 6, 10, 20, 52 and 58 can be easily cleaned or replaced.

Since the indoor unit of the air conditioner according to the present invention configured as described above is equipped with a filter frame on the upper side of the base and a filter is disposed on the filter frame, the air sucked to the base side can be purified to purify the air more quickly. There is an advantage in that it is possible to increase the air purification performance.

In addition, the filter frame has a filter support rib is formed so that the filter is sliding mounted, there is an advantage that the cleaning or replacement of the filter is easy.
