FlG. 1, and the memory slot 612 or the external input terminal 614 can be installed on the cabinet 20 of the air conditioning unit 100 referring to the installation place of the control unit 500.

[80] Also, the audio output unit 260, as described, is to output the audio signal, from the converted signal that went through the signal converter 220, to the user, where the speaker 616 for the audio output and the external output terminal (not indicated) is installed on the case. [81] On the other hand, the display unit 200 is combined with the front panel 22 by the connecting unit 600. In detail, the connecting unit 600 connects the case of the display unit 200 and the front panel 22 of the air conditioning unit 100, so that when the exchange or cleaning of the filter 60, or when detaching, opening and closing of the display unit 200 is done with ease.

[82] In detail, the connection unit 600 constitutes; the 1st link 620 and the 2nd link 630 is each hinge connected to the back of the case 610 and the front panel 22. Also, the 2nd link 630 is situated in the lower part of the 1st link 620, and is formed longer than the 1st link 620. Also, in this example, all the ends of the 1st link 620 and the 2nd link 630 is connected, where all the ends are to be turned in up and down direction.

[83] Also, on the back of the case 610, a bracket 622/632 is formed on each of one end of the 1st link 620 and the 2nd link 630 so that the both link could be hinge connected, and on the front of the front panel 22 a bracket 623/633 is formed on each of the other end of the 1st link 620 and the 2nd link 630 so that the both link could be hinge connected. Also, the other end of the 2nd link 630 is combined with the bracket 633 to be able to slide with the bracket. Especially, when the display unit 200 and the air conditioning unit 100 is separated, the other end of the 2nd link 630 will rise following the bracket 633 and is separated from the front panel 22.

[84] Also, the case 610 and the front panel 22 is fit bonded. In detail, a hook 642 is formed on the back of the case 610, and hook bracket 644 is formed on the front panel 22, which is fit bonded with the hook 642. So, when the display unit 200 and the cabinet 20 is bonded, and when the case 610 of the display unit 200 where the 1st link 620 and the 2nd link 630 is hinge connected, the hook 642 and the hook bracket 644 is fit bonded. Also, a grill 650 is formed on the back of the case 610, and the case 610 and the front panel 22 is lifted in a fixed amount.

[85] FIG. 6 is a perspective view illustration of the operation status of the air conditioner according to the present invention.

[86] Referring to FIG. 6, when the air conditioning unit 100 is activated, the indoor ventilator 30 is activated, and the room air is circulated from the activated above indoor ventilator 30 through the cabinet 20.

[87] In detail, the room air flows in through the inlet 25 formed in the front panel 22, then flows out through each outlet 26 of the base 24.

[88] Especially, in this example, since the inlet 25 is formed in the front panel 22, the room air flows in through the space between the case 610 of the display unit 200 and the front panel 22, and moves to the indoor ventilator 30 through the filter 60.

[89] On the other hand, each outlet unit 26 installed in the outlet 26 is controlled by the control unit 500, and only when the air conditioning unit 100 is activated the outlet 26 is opened by the vane 92 turning. [90] From here, when the air conditioning unit 100 is activated, the air flowing from the lifted space between the front panel 22 and the case 610 moves to the inlet 25, contacting with the back of the display unit 200. So, the air from the inlet will act to cool the heat unit of the display unit 200. In detail explanation, the air from the inlet absorbs the heat discharged from the display panel 250 and electronic parts when contacting the back of the display unit 200. Also, the air with high temperature, which absorbed the heat, is cooled when penetrating the indoor heat exchange unit 50 of the air conditioning unit 100. Also, the cooled air, from the indoor heat exchange unit 50, goes out though the outlet 26 back to the room.

[91] So, when the display unit 200 and the air conditioning unit 100 is both active, even though at hot situations the temperature of the display unit 200 will not rise. So, the inlet air to cool the room air will also act to cool the display unit 200 at the same time.

[92] Contrary, when the heat function is activated, the inlet room air absorbs heat primary from the display unit 200, the air penetrating indoor heat exchange unit 50 will rapidly be heated, increasing the heat efficiency.

[93] Also, since the air conditioning unit 100 is situated in the back of the display unit

200, the exposure area of the air conditioning unit 100 will be minimized to the user.

[94] Also, when only the display unit 200 is active, and when only the indoor ventilator

30 from other components of the air conditioning unit 100 is active by the control unit 500, the heat unit of the display unit 200 will be cooled due to the air flow. So, it will be unnecessary to install the cooler unit for the display unit 200, resulting minimizing the component requirement for the display unit.

[95] FIG. 7 is a side view of the air conditioner according to the present invention and

FIG. 8 is a side view of the opened status of the display unit from the air conditioning unit according to the present invention.

[96] In detail, one side of the 1st link 620 and the 2nd link 630, while connected to the case 610, is relatively situated in front of the other side while the case 610 is closely attached to the front panel 22.

[97] Especially, as the gravity center of the case 610 is situated in front of the front panel

22, by the connecting unit 600, the case 610 is fixed on to the front panel 22 by the hook 642 and the hook bracket 644.

[98] So, if the user releases the bond status of the hook 642 and the hook bracket 644, which fixes the front panel 22 and the case 610, the case 610 will relatively move to the front panel 22.

[99] In detail, when the bond between the hook 642 and the hook bracket 642 is released, the display unit 200 will fall to the front while rotating, by the 1st link 620 and the 2nd link 630.

[100] Like the, according to the present invention, the case 610, which is installed on the indoor air conditioner and fixed on to the front panel 22, is easily moved from the front panel 22, by the user pushing and releasing one touch control. Also, the user can easily exchange the filter, which is installed on the front panel 22 through the moved space between the front panel 22 and the case 610.

[101] Also, the service man, who repairs or checks the air conditioner, can easily separate the case 610 and the cabinet 20 through the connecting unit 600.

[102] For example, if the display unit 200, which is installed on the case 610, needs a service due to a malfunction and etc, the service man can separate the 1st link 620 and the 2nd link 630 of the connecting unit 600 to separate only the display unit 200 from the cabinet 20. Also, from the separation, the checking of the display unit 200 is done easily.

[103] Also, as the air conditioning unit, which is installed on the cabinet 20, functions well while the display unit 200 is separated, the user can operate the air conditioning unit 100 normally while the display unit 200 is under repair.

[104] Also, when the air conditioning unit 100 is malfunctioning, the service man can separate the case 610 and easily check the inside of the cabinet 20 through the front panel 22.

[127] From here, the slider 820 is formed on a T formation on the flat surface and the slide rail 810 is formed on a

formation on the flat surface. By this formation, when the slide 820 is inserted in up/ down direction to the slide rail 810, while the movement in up/down direction of the case 610 is possible but the movement in front/back direction is limited. So, the separation of the case 610 from the cabinet 20 is prevented.

[128] Also, as the user can open and close the front surface of the front panel 22 of the cabinet 20 by lifting the case 610 in up direction; the cleaning and exchanging of the filter 60, which is installed on the front panel 22, and the separation of the front panel 22 is easily done. Also, the lower part of the slide rail 810 is closed to prevent the slider 820 from dropping.

[129] Also, as the case 610, which is installed on the display unit 200, is supported by the cabinet 20 by bonding with the slider 820 and the slide rail 810, the safety and reliability is increased due to the bonding.

[130] Also, as the slide rail 810, which is fixed on to the bottom surface of the case 610, or the slider 820 is installed on the bottom surface of the case 610 in up/down direction, the hardness against the bending or the twisting of the case 610 is increased.

[131] On the other hand, the installation place of the slide rail 810 and the slider 820 can be installed in the opposite way, and the formation of the slide rail 810 and the slider 820 can be altered in many ways in extent of this example according to the present invention.

[132] The rest explanation of the 3rd example will be excluded, as it is identical to the 1st example. Mode for the Invention
