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 raising and lowering a discharge port unit by raising and lowering a height and diffusing and discharging cold or warm air from side to 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 installs the indoor unit of cooling / heating function on the indoor side and the outdoor unit of heat dissipation / cooling and compression function on the outdoor side and connects the two separated devices by refrigerant piping. The one-piece type integrates the function of cooling, heat dissipation and compression, and directly installs a hole in the wall of the house or hangs the device on the window.

11 and 12, the indoor unit of the conventional air conditioner, the air inlet 101a is formed in the lower front, the air outlet 102a is formed in the upper front, the heat exchanger 120 therein And a blower 130.

The indoor unit is equipped with a plurality of louvers 105 to protect the inside of the air discharge port (102a).

The indoor unit of the air conditioner as described above, after the air sucked through the air intake port 101a when the blower 130 is driven, is cooled / heated by the heat exchanger 120 and then through the air discharge port 102a. It is discharged toward the upper front of the indoor unit.

On the other hand, if the indoor unit of the air conditioner is to adjust the height of the air discharge port (102a) up and down, depending on the size of the indoor space to be cooled / heated, or the arrangement structure of the personnel, furniture or equipment in the space, Convection can be done efficiently.

As an example of adjusting the position of the air discharge port 102a of the indoor unit of the air conditioner as described above, there is an air conditioner having a liftable louver of Korean Patent Publication No. 10-0149375.

As shown in FIGS. 11 and 12, the air conditioner having the liftable louver includes a main body 101 in which an indoor unit is provided with an air suction part at a lower front side thereof, and a system for processing air therein, and a main body part ( The main body from the lower end of the louver portion 102 between the main louver portion 102 and the main louver portion 102 having an air discharge port for discharging air, that is, cold or warm air, which has been processed at 101. It consists of a connecting part 103 extending toward the part 101.

In addition, the rear of the main body portion 101 is provided with a screw shaft 108 extending vertically upward, the screw shaft 108 is coupled to the drive shaft of the drive motor 102, the lower end of which can be forward and backward driving (114) It is connected through the), the louver portion 102 is provided with a nut shaft 109 engaging with the screw shaft 108.

The air conditioner having the liftable louver rotates the screw shaft 108 when the driving motor is driven, and the louver portion 102 of the main body portion 101 according to the rotation direction of the screw shaft 108. Ascending and lifting from the upper side, the height of the air discharge port is variable.

However, since the indoor unit of the air conditioner according to the prior art has an air intake port formed only on the front surface of the main body portion 101, and the air discharge port is formed only on the front surface of the louver portion 102, the air sucked into the front lower portion of the indoor unit Indoors can be discharged only to the front of the indoor unit is difficult to indoor three-dimensional cooling / heating, the louver 102 is elevated only for adjusting the position of the air discharge port and because the inside of the main body 101 can not enter, the indoor unit There is a problem that foreign matters can penetrate through the air outlet when not operating.

And, the indoor unit of the air conditioner can be easily stored or transported when the height can be reduced. Since the louver portion 102 is elevated only to adjust the height of the air discharge port, the size of the indoor unit cannot be reduced. There is a problem that is not easy.

The present invention has been made to solve the above problems of the prior art, the object of the present invention is to provide an indoor unit of an air conditioner that is easy to store or move by varying the height, and that can be left and right three-dimensional cooling / heating.
