The present invention relates to an indoor unit of an air conditioner, and more particularly, to an indoor unit of an air conditioner such that the heat exchanger is not visible from the front side and the color of the front side is easily changed.

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.

Recently, in consideration of three-dimensional cooling and heating, there is a trend of forming an air discharge port through which air is discharged to the side or the top of the indoor unit.

As shown in FIGS. 8 to 11, 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, and the air inlets 104d and 104e are formed on both sides of the lower side, 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. It is mounted rotatably.

The front panel 104 is formed such that both sides are inclined and the front upper panel 105 having the front air outlet 104a and the side air outlets 104b and 104c, the center lower portion of the front upper panel 105 and the The front lower panel 106 is disposed between the base 101 and forms the air inlets 104d and 104e between lower portions of both sides of the cabinet 102.

An air filter 109 is mounted on the rear surface of each of the left and right suction grills 107 and 108 so that foreign matters in the air passing through the air suction ports 104d and 104e can be filtered.

In addition, the front panel 104 includes an elevating mechanism composed of a motor and a gear for elevating the vertical drive panel 110, a retracting mechanism composed of a motor, a gear, etc. for advancing the front and rear drive panel 112, and A rotating mechanism composed of a motor or the like for rotating each of the left and right vanes 114 and 116 is mounted.

Meanwhile, left and right electrostatic precipitators 121 which ionize and collect foreign substances in the air passing through the left and right suction grills 107 and 108 and the air filter 109 on both sides of the front part of the front of the blower 120. 122 is disposed.

When the indoor unit of the conventional air conditioner configured as described above is driven by the blower 120, the indoor air is sucked into the indoor unit through the left and right suction grills 107 and 108 and the air filter 109. The foreign materials, such as dust, are ionized and collected while passing through the left and right electrostatic precipitators 121 and 122, and are blown by the blower 120 to the heat exchanger 130.

The air blown by the heat exchanger 130 is cooled / heated by heat exchange with a refrigerant and then discharged back into the room through the front air outlet 104a, the left air outlet 104b, and the right air outlet 104c. Cool / heat up.

However, the indoor unit of the air conditioner according to the prior art does not look good because the upper part of the heat exchanger 130 is visible behind the front air outlet 4a, and is vertically driven to open and close the front air outlet 104a. Due to the panel 112 and the front and rear driving panel 112, the structure of the front panel 104 is complicated, and color change of the front panel 104 is not easy.

In addition, when the air filter 109 is cleaned or replaced, the left and right suction grills 107 and 108 should be opened and the air filter 109 should be separated from the rear of the left and right suction grills 107 and 108. However, when the left and right suction grill 107, 108 frequently open and close there is a problem that the connection portion is easy to break.

The present invention has been made to solve the above-mentioned problems of the prior art, the object of the present invention is to provide an indoor unit of an air conditioner that improves aesthetics and easily changes the color of the front side.

Another object of the present invention is to facilitate the removal of the air purifier.
