As shown in FIG.

Looking at the operation of the air conditioner according to the present invention configured as described above are as follows.

First, when the user requests the operation of the air conditioner 1, the left and right suction vanes 62 and 72 open the air suction ports 61 and 71, and the upper discharge vane 81 ) And the left and right side discharge vanes 57 and 58 open the upper air outlet 80 and the side air outlets 55 and 56, respectively.

When the blower 110 is driven, external air is sucked into the air conditioner 1 through the air inlets 61 and 71 by the blowing force of the blower 110. The air sucked into the air conditioner 1 is purified while passing through the left and right suction filters 63 and 73 and then moved to the front of the blower 110.

The air moved to the front of the blower 110 is purified in stages while sequentially passing through the central filter 121. After passing through the central filter 121, the air passes through the blower 110, and is blown to the upper side of the blower 110 to be heat exchanged by the heat exchanger (100).

The air heat-exchanged by the heat exchanger 100 is discharged to the outside of the air conditioner 1 through the upper air outlet 80 and the side air outlets 55 and 56.

At this time, since the left and right air guides 181 and 182 are installed at the rear surface 50a of the upper panel 50 corresponding to the front of the heat exchanger 100, the heat exchanger 100 The heat exchanged toward the rear portion 50a of the upper panel 50 exits the side air outlets 55 and 56 along the left and right air guides 181 and 182.

That is, as shown in FIG. 8, some of the heat exchanged air in the heat exchanger 100 is guided along the vane guide part 181a of the left air guide 181, so that the left side discharge vane 57 is provided. Bumped into Air hitting the left side vane 57 is switched to the flow path is discharged toward the front center of the air conditioner (1). And, the rest of the heat exchanged air in the heat exchanger 100 passes between the left side discharge vane 57 and the discharge port guide portion 181b of the left air guide 181, the air conditioner (1) Is discharged in the lateral direction. The role of the right air guide 182 is also the same.

Therefore, since the air discharged by heating / cooling can be discharged not only in the side direction of the air conditioner 1 but also in the front center side, more three-dimensional cooling / heating can be achieved.

In addition, the switch cover part 184 is formed at the left and right air guides 181 and 182 to prevent cold air from being directly transmitted to the switch 190, thereby preventing malfunction of the switch 190. You can do it.

9 is a cross-sectional view of the upper panel of the air conditioner according to the second embodiment of the present invention.

The air conditioner according to the second embodiment of the present invention includes an air guide 200 formed to guide the air air-conditioned in the heat exchanger 100 toward the left and right side discharge vanes 57 and 58, and the air The guide 200 has the same configuration and operation as that of the first embodiment except that the guide 200 is integrally formed on the upper panel 50, and thus, description of the guide 200 will be omitted. The same code | symbol is written together about the same structure as an Example.

That is, as shown in FIG. 9, the air guide 200 according to the second embodiment is formed at the left and right sides of the rear part 50a of the upper panel 50, respectively. Between the side portions 51 and 52 and the back portion 50a is bent, the air guide 200 may be molded together when the upper panel 50 is manufactured.

Therefore, the air heated / cooled in the heat exchanger 100 is guided to the left and right side discharge vanes 57 and 58 along the air guide 200, and hit the left and right side discharge vanes 58. After the flow path can be switched to the front side of the air conditioner (1).

10 is a cross-sectional view of the upper panel of the air conditioner according to the third embodiment of the present invention.

An air conditioner according to a second embodiment of the present invention includes an air guide 210 formed to guide the air heated / cooled in the heat exchanger 100 to the left and right discharge vanes 57 and 58, The air guide 210 is integrally formed on the upper panel 50, and a portion of the rear portion 50a of the upper panel 50 is inclined toward the side portions 51 and 52 of the upper panel 50. Except for the formation, other configurations and operations are the same as those of the first embodiment, and thus, the description of the same configuration as that of the first embodiment will be omitted and the same reference numerals will be given.

That is, as shown in FIG. 10, the air guide 210 according to the third embodiment is formed at the left and right sides of the rear part 50a of the upper panel 50, respectively. The left and right sides of the back portion 50a are inclined upwardly toward the side air outlets 55 and 56 so that the air heated / cooled in the heat exchanger 100 is along the air guide 210 along the left and right sides. Guided to discharge vane sides 57 and 58. Therefore, after the discharged air guided by the air guide 210 hits the left and right side discharge vanes 57 and 58, the flow path may be switched to the front side of the air conditioner 1.

The air conditioner according to the present invention includes an air guide provided between the air conditioner and the vane, so that at least a part of the air air-conditioned in the air conditioner is guided to the vane side along the air guide to hit the vane, and then the air Since it can be discharged to the front side of the conditioner, not only the side discharge but also the forward discharge is possible, and thus there is an effect capable of more efficient three-dimensional cooling / heating.

In addition, the air guide is installed on the upper panel to include a switch cover surrounding the switch to detect the opening and closing of the front panel, thereby preventing cold air from penetrating the switch by the air cooled in the air conditioning unit, There is an effect that can prevent malfunction and failure.

In addition, since the air guide is installed to cover the inside of the air inlet and outlet, there is an advantage that the inside of the upper panel can be prevented from being exposed to the outside.

In addition, since the safety net installed in the air entrance and exit can be coupled to the air guide, there is an advantage that the assembly of the safety net is easy.
