4 and 5 are front and rear perspective views of the rear frame 300, respectively. The configuration of the rear frame 300 will be described in detail with reference to these drawings.

The rear surface of the rear frame 300 is stepped. Specifically, the front and rear lengths of the rear frame 300 are different from each other in the upper half and the lower half. That is, the length of the lower half of the rear frame 300 is larger than the length of the upper half of the upper half.

Accordingly, a stepped surface 350 is formed at a central portion of the rear frame 300. That is, a stepped surface 350 formed horizontally is formed below the outer air inlet 302 formed in the upper half of the rear frame 300.

A duct connecting port 352 is formed in the stepped surface 350 so as to pass through the upper and lower surfaces.

The bottom surface of the drain guide groove 762 is sloped to the left. That is, the bottom surface of the drain guide groove 762 is inclined so that its height gradually decreases toward the direction in which the drop hole 752 is formed (left side in FIG. 20). Accordingly, the flow of the condensed water smoothly occurs due to such inclination.

A drain avoidance port 764 is formed on the left side surface 750b of the auxiliary drain pan 750. The drain avoiding opening 764 is formed by cutting a part of the left side surface 750b of the auxiliary drain pan 750 so that when the auxiliary drain pan 750 and the main drain pan 700 are coupled, So as to prevent interference with the housing receiving groove 710 of the fan 700.

A drain avoiding surface 766 is also formed on the right side surface 750c of the auxiliary drain pan 750 facing the drain avoidance hole 764. That is, the first half of the right side 750c of the auxiliary drain pan 750 is sloped to the right to form a drain avoiding surface 766. Such a drain avoiding surface 766 is also formed in the housing 754, So as to avoid interference with the seating groove 710.

The connector fastening portion 768 is formed at the right end of the auxiliary drain pan 750. The connector fastening portion 768 is a portion to which one end of the condensed water pipe 560 is fastened, and has a U-shaped upper opening.

A drain hook 770 is formed at the right end and the rear end of the auxiliary drain pan 750, respectively. The drain hook 770 is formed of a hook having a hook shape and protrudes upward from the right end of the auxiliary drain pan 750.

The drain hook 770 serves to primarily assemble the auxiliary drain pan 750 to the main drain pan 700. That is, when the drain hook 770 is inserted and fastened to a drain hook groove (not shown) formed in the main drain pan 700, the auxiliary drain pan 750 is inserted into the main drain pan 700 And is subsequently combined.

The auxiliary drain pan 750 is formed with a plurality of drain fastening protrusions 772, 774 and 776 for fastening the auxiliary drain pan 750 to the main drain pan 700. Accordingly, the plurality of drain fastening protrusions 772, 774, 776 are respectively formed at positions corresponding to the drain coupling portions 736, 737, 739 of the main drain pan 700 described above.

More specifically, a front drain fastening protrusion 772 and a rear drain fastening protrusion 774 protrude forward and rearward from the front surface 750d and the rear surface 750e of the auxiliary drain pan 750, respectively. A front drain coupling groove 772 'and a rear drain coupling groove 774' are formed at the center of the protrusion 772 and the rear drain coupling protrusion 774, respectively.

Three right-side coupling projections 776 are formed at the right end of the auxiliary drain pan 750. At the center of each right-side drain fastening protrusion 776, a right-side drain coupling groove 776 'for fastening the fastening member is formed.

Heat exchange coupling portions 780 and 782 for coupling with the first heat exchanger 510 are formed in the auxiliary drain pan 750, respectively. A front heat exchange coupling part 780 protrudes forward from the front surface 750d of the auxiliary drain pan 750 and a rear heat exchange coupling part 782 is formed at the rear end of the bottom surface 750a of the auxiliary drain fan 750.

The heat exchange supporting ribs 784 protrude downward from the bottom surface of the auxiliary drain pan 750 at a predetermined distance, and the upper right end of the first heat exchanger 510 is in contact with the heat exchange supporting ribs 784. Therefore, the first heat exchanger 510 is supported by the heat exchange supporting ribs 784, so that the first heat exchanger 510 is prevented from falling.

A plurality of orifice fastening ribs 786 are formed at the left end (the tip end in FIG. 21) of the auxiliary drain pan 750. The orifice coupling ribs 786 are for coupling the lower orifice 600 to the auxiliary drain pan 750.

The orifice fastening ribs 786 are formed of a pair of ribs spaced apart from each other by a predetermined distance. A hook 786 'is formed in one of the pair of ribs (the rib on the rear side in FIG. 21). Therefore, when the orifice fastening rib 786 is inserted into the orifice fastening hole (not shown) formed on the upper orifice 600, the fastening rib 786 is not caught by the fastening protrusion 786 '.

Hereinafter, the operation of the air conditioner according to the present invention will be described.

First, the flow of refrigerant and air in the air conditioner according to the present invention will be described.

The air conditioner according to the present invention can be used for cooling or heating. Here, the case where the air conditioner according to the present invention is used for cooling will be described as an example.

At this time, the first heat exchanger 510 serves as a condenser, and the second heat exchanger 860 serves as an evaporator. A refrigerant pipe (not shown) is connected between the compressor 520 and the first heat exchanger 510 and the second heat exchanger 860 to guide the flow of the refrigerant.

Accordingly, when the gas refrigerant from the compressor 520 is compressed and flows into the first heat exchanger 510 in a state of high temperature and high pressure, the refrigerant is condensed by heat exchange with the outside air in the first heat exchanger 510 do.

The condensed refrigerant then expands while passing through an expansion valve (not shown) and enters the second heat exchanger 860. The refrigerant flowing into the second heat exchanger 860 undergoes heat exchange with the outside air and evaporates. Therefore, the refrigerant becomes a gaseous state, and at this time also the refrigerant in a liquid state remains, and actually two-phase refrigerant is mixed.

The refrigerant passes through the accumulator 530 and is then sent to the compressor 520 to complete the circulation cycle of the refrigerant.

Meanwhile, air passes through the first heat exchanger 510 and the second heat exchanger 860 to perform heat exchange. This process will be described with reference to FIGS. 1, 2, and 22.

'로 표시됨)을 살펴본다. 이때의 공기 유동은 기본적으로 상기 하부팬(630)에 의해 발생하게 된다. 즉, 외부로부터 인가되는 전원에 의해 상기 하부모터(660)가 구동하게 되면, 이러한 하부모터(660)의 축에 연결되어 있는 상기 하부팬(630)이 회전하면서 공기의 유동을 발생시키는 것이다.First, the air flow (in the figure, '

'). At this time, the air flow is basically generated by the lower fan 630. That is, when the lower motor 660 is driven by an external power source, the lower fan 630 connected to the shaft of the lower motor 660 rotates to generate air flow.

Therefore, the rear air flows through the lower grill 330 formed at the lower half of the rear frame 300. [ The air flowing forward through the lower grill 330 is diverted to flow to the left side and passes through the first heat exchanger 510.

The temperature of the air passing through the second heat exchanger 860 rises. That is, since the second heat exchanger 860 serves as a condenser, heat is received from the refrigerant flowing in the second heat exchanger 860, and the air is in a high temperature state.

The hot air passing through the second heat exchanger 860 passes through the lower orifice hole 602 and flows into the center of the lower fan 630. The air flowing into the central portion of the lower fan 630 flows radially by the rotation of the lower fan 630 and is guided by the exhaust guide 650 and discharged upward.

The high temperature air guided upward by the exhaust guide 650 is completely discharged to the outside of the building through the exhaust means 400.

'로 표시됨)을 살펴본다. 이때의 공기 유동은 기본적으로 상기 상부팬(840)에 의해 발생하게 된다. 즉, 외부로부터 인가되는 전원에 의해 상기 상부모터(820)가 구동하게 되면, 이러한 상부모터(820)의 축에 연결되어 있는 상기 상부팬(840)이 회전하면서 공기의 유동을 발생시키는 것이다.Next, the flow of the air that occurs at the heat absorption side (the upper portion of the main drain pan)

'). At this time, the air flow is basically generated by the upper fan 840. That is, when the upper motor 820 is driven by an external power source, the upper fan 840 connected to the shaft of the upper motor 820 rotates to generate air flow.

Accordingly, the outside (indoor space) air flows inward (forward) through the suction grille 310 formed on the upper half of the rear frame 300. The air introduced through the suction grille 310 passes through the pre-filter 320 and the deodorizing filter 322 in order to remove foreign substances and odors in the air.

The air having passed through the pre-filter 320 and the deodorizing filter 322 passes through the second heat exchanger 860, and heat exchange occurs in this process. That is, since the second heat exchanger 860 functions as an evaporator, air passing through the second heat exchanger 860 is cooled by heat exchange with the refrigerant.

The low-temperature air having passed through the second heat exchanger 860 flows forward through the upper orifice hole 852 and flows into the center of the upper fan 840. The air introduced into the center of the upper fan 840 is radially discharged by the rotation of the upper fan 840, and the air is guided by the upper fan housing 810 to flow upward.

The air flowing upward by the upper fan housing 810 is forwarded through the discharge guide 814 of the upper air guide 800 and passes through the discharge louver 110. [ The low-temperature air passing through the discharge louver 110 is discharged to the front of the discharge port 210 to cool the indoor space. Meanwhile, air passing through the discharge louver 110 is also diverted by a plurality of ribs formed in the discharge louver 110.

Next, a process of fastening the suction grille 310 to the rear frame 300 will be schematically described.

First, the suction grille 310 is brought close to the rear of the rear frame 300. Then, the grill fastening protrusion 317 formed at the lower end of the suction grill 310 is inserted into the grill projection insertion hole 354.

After the grille fastening protrusion 317 is inserted into the grille projection insertion hole 354, the upper end of the suction grille 310 is pushed forward. Then, a grill fastening hook 316 formed on the upper end of the suction grill 310 is inserted into the grill hook fastening hole 374. When the grill fastening hook 316 is inserted into the grill hook fastening hole 374, the grill fastening hook 316 is prevented from being separated by the fastening portion 316 'formed at the front end of the grill fastening hook 316.

In this manner, the suction grill 310 is mounted on the rear frame 300. In order to separate the suction grille 310 mounted by the above-described process, the suction grille 310 is reversed according to the above-described installation.

That is, in order to separate the suction grille 310, the removal rib 315 is pulled forward while being held by a hand. As a result, the grill fastening hook 316 flows to the left and right due to its own elasticity, so that the retaining portion 316 'of the grill fastening hook 316 moves backward through the grill hook fastening hole 374 .

Then, the suction grille 310 is lifted upward. The grill fastening protrusion 317 of the suction grill 310 is separated from the grill projection insertion hole 354 and is released upward. By this process, the suction grill 310 is completely separated.

On the other hand, in order to lift the air conditioner as described above, the user must raise his / her hand while holding the hand on the pair of handles 340. At this time, it is preferable to stand up in front of the above-mentioned air conditioner. That is, since the inner space of the handle 340 is gradually widened toward the rear side, it is preferable that the human perception (second finger) is positioned at the inner rear end of the handle 340.

In order to assemble the knob 340 to the knob hole 342, it is possible to apply the force by pressing the knob 340 on both sides. That is, since the fixing rib 348 of the handle 340 is inclined at one side to form the guide surface 348 '', when the handle 340 is pushed into the handle hole 342, And this guide surface 348 " slides in contact with the rim of the handle hole 342. [

Thus, when the force is applied to the inner side of the handle 340 in this state, the fixing rib 348 finally moves to the inside of the handle hole 342, As shown in Fig. In this case, the mounting of the handle 340 is completed.

Meanwhile, the condensed water on the upper surface of the main drain pan 700 flows into the housing receiving groove 710 as well. That is, since the housing receiving groove 710 is formed at a lower position than the upper surface of the main drain pan 700, part of the condensed water moves to the housing receiving groove 710.

The condensed water moved to the housing receiving groove 710 is guided by the groove dividing rib 712 and gradually moves to the lower portion of the housing receiving groove 710. Then, it moves downward through the groove condensate holes 714 formed at the lowermost end of the housing receiving recess 710.

The condensed water holes 704 and 714, that is, the condensed water that has passed through the bottom condensed water hole 704 and the groove condensate water hole 714 and moves to the lower side of the main drain pan 700 is drawn through the inner surface of the condensed water drop guide 716 And finally falls at the lower end of the condensate drop guide 716 and then drops downward.
