The drain hook 770 serves to allow the auxiliary drain pan 750 to be temporarily assembled to the main drain pan 700. That is, when the drain hook 770 is inserted into and fastened to a drain hook groove (not shown) formed in the main drain pan 700, the auxiliary drain pan 750 is connected to the main drain pan 700. It is combined automatically.

A plurality of drain fastening protrusions 772, 774, and 776 are formed in the auxiliary drain pan 750 to allow the auxiliary drain pan 750 to be fastened to the main drain fan 700. Accordingly, the plurality of drain fastening protrusions 772, 774 and 776 are formed at positions corresponding to the drain fastening portions 736, 737, and 739 of the main drain pan 700 described above, respectively.

In more detail, the front drain fastening protrusion 772 and the rear drain fastening protrusion 774 are formed to protrude forward and backward at the top of the front 750d and the rear 750e of the auxiliary drain pan 750, respectively. At the centers of the protrusion 772 and the rear drain fastening protrusion 774, front and rear fastening grooves 772 ′ and rear drain fastening grooves 774 ′ to which the fastening protrusions are fastened are formed, respectively.

In addition, three right drain fastening protrusions 776 are formed at the right end of the auxiliary drain pan 750. In addition, a right drain fastening groove 776 ′ through which the fastening member is fastened is formed at the center of each of the right drain fastening protrusions 776.

In the auxiliary drain fan 750, soft exchange coupling parts 780 and 782 for coupling with the first heat exchanger 510 are formed before and after, respectively. That is, the front heat exchange fastening portion 780 protrudes forward from the front side 750d of the auxiliary drain pan 750, and the rear heat exchange fastening portion 782 is formed at the rear end of the bottom surface 750a of the auxiliary drain pan 750. ) Is formed. In addition, the front heat exchange fastening part 780 and the rear heat exchange fastening part 782 are formed with a front heat exchange fastening hole 780 ′ and a rear heat exchange fastening hole 782 ′ through which the fastening member can pass.

In addition, a heat exchange support rib 784 is formed long in the longitudinal direction at the bottom right end (rear end in FIG. 21) of the auxiliary drain pan 750. The heat exchange support ribs 784 protrude downwardly from the bottom of the auxiliary drain pan 750, and the upper right side of the first heat exchanger 510 is in contact therewith. Therefore, the first heat exchanger 510 is supported by the heat exchange support ribs 784 to prevent the fall.

A plurality of orifice tightening ribs 786 are formed at the left end of the auxiliary drain pan 750 (a front end in FIG. 21). The orifice tightening rib 786 is to allow the auxiliary drain pan 750 to fasten the lower orifice 600 to each other.

The orifice fastening rib 786 is composed of a pair of ribs spaced at predetermined intervals, and one of the pair of ribs (rear rib in FIG. 21) is formed with a locking step 786 ′. Therefore, when the orifice fastening rib 786 is inserted into an orifice fastening hole (not shown) formed on the upper surface of the lower orifice 600, the orifice fastening rib 786 is not caught by the locking jaw 786 ′.

In addition, as described above, the drop hole 752 formed in the auxiliary drain pan 750 is located above the right side of the first heat exchanger 510. The structure of the heat exchanger 510 is demonstrated concretely.

22 and 23 show a perspective view and a plan view of the first heat exchanger 510, respectively.

As shown in these figures, the first heat exchanger 510 is provided with heat exchange fins for increasing the contact area with air in a vertical manner, and a heat exchange tube 512 is installed across the heat exchange fins vertically. .

The heat exchange tube 512 is formed to communicate with the refrigerant pipe (not shown) described above to guide the refrigerant to flow inside the first heat exchanger 510. The heat exchange tube 512 is installed in a zigzag before and after. That is, when viewed from the side is made of a continuous 'S' shape.

The heat exchange tube 512 is formed in three rows. That is, the first row 512a is formed near the right side of the first heat exchanger 510, and the second row 512b and the third row 512c are formed in turn toward the left. In addition, the third row 512c has a drop hole 752 formed in the auxiliary drain pan 750 located below. Therefore, the condensed water falling downward through the drop hole 752 of the auxiliary drain pan 750 is evaporated while flowing down to the upper portion of the third row 512c.

In detail, the drop hole 752 of the auxiliary drain pan 750 is formed from the lower fan 630 or the lower orifice 600 among the heat exchange tubes 512 formed in three rows of the first heat exchanger 510. It is to fall to the upper side of the first row (512a) formed in the relatively farthest position. That is, it falls to the right side corresponding to the suction side of the air passing through the first heat exchanger 510.

As such, the condensed water flowing from the drop hole 752 of the auxiliary drain pan 750 falls to the right side surface of the first heat exchanger 510 located opposite the lower fan 630 or the lower orifice 600. That is, the first column 512a formed at a position relatively farthest from the lower fan 630 or the lower orifice 600 falls. Therefore, since the air directly entering the first heat exchanger 510 is directly encountered, evaporation of the condensed water occurs better.

It looks at the operation of the air conditioner according to the present invention as described above.

First, look at the flow of the refrigerant and air in the air conditioner according to the present invention.

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.

In this case, 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, the first heat exchanger 510, and the second heat exchanger 860 to guide the flow of the refrigerant.

Therefore, when the gas refrigerant is compressed from the compressor 520 to a high temperature and high pressure and flows into the first heat exchanger 510, the refrigerant is condensed by heat exchange with 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 introduced into the second heat exchanger 860 evaporates by exchanging heat with outside air. Therefore, the refrigerant is in a gaseous state, in which a liquid refrigerant also remains, and in fact, two-phase refrigerants are mixed.

After the refrigerant passes through the accumulator 530, the refrigerant is sent back to the compressor 520 to complete a cycle of the refrigerant.

Meanwhile, the air exchanges heat while passing through the first heat exchanger 510 and the second heat exchanger 860. This process will be described with reference to FIGS. 1, 2, and 24.

(Marked with '). Air flow at this time is basically generated by the lower fan 630. That is, when the lower motor 660 is driven by a power applied from the outside, the lower fan 630 connected to the shaft of the lower motor 660 rotates to generate air flow.

Therefore, the rear air is introduced 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 changed in direction and flows to the left, and passes through the first heat exchanger 510.

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

The hot air passing through the second heat exchanger 860 passes through the orifice hole 602 and flows into the center of the lower fan 630. The air introduced into the center 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 hot air guided upward by the exhaust guide 650 is completely discharged to the outside of the building through the exhaust guide 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 air occurring at the endothermic side (upper part of the main drain pan) (

(Marked with '). Air flow at this time is basically generated by the upper fan 840. That is, when the upper motor 820 is driven by a power applied from the outside, the upper fan 840 connected to the shaft of the upper motor 820 rotates to generate a flow of air.

Therefore, the air of the outside (indoor space) is introduced into the inside (front) through the suction grill 310 formed in the upper half of the rear frame 300. The air flowing through the suction grille 310 passes through the prefilter 320 and the deodorizing filter 322 in order, and foreign matters or odors in the air are removed in this process.

The air passing through the prefilter 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 acts as an evaporator, the air passing through the second heat exchanger 860 is cooled by heat exchange with a refrigerant.

The low-temperature air passing 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.

Air flowing upward by the upper fan housing 810 passes forward 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, the air passing through the discharge louver 110 may be switched in direction by a plurality of ribs formed in the discharge louver 110.

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

First, the suction grill 310 is approached from 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 protrusion insertion hole 354.

After the grill fastening protrusion 317 is inserted into the grill protrusion insertion hole 354, the upper end of the suction grill 310 is pushed forward. In this case, the grill fastening hook 316 formed at the upper end of the suction grill 310 is inserted into the grill hook fastening hole 374. When the grille fastening hook 316 is inserted into the grille hook fastening hole 374, separation is prevented by a catching part 316 ′ formed at the front end of the grille fastening hook 316.

By the above process, the suction grill 310 is mounted to the rear frame 300. In addition, in order to separate the suction grill 310 mounted by the above process, the reverse order of the above-described mounting is performed.

That is, in order to separate the suction grill 310, the pull-away rib 315 is pulled forward while being held by hand. In this case, the grill fastening hook 316 flows left and right by its elasticity so that the locking portion 316 ′ of the grill fastening hook 316 moves backward through the grill hook fastening hole 374. .

Then, the suction grill 310 is lifted upward. In this case, the grill fastening protrusion 317 of the suction grill 310 is separated from the grill protrusion insertion hole 354 to be separated upward. By this process, the separation of the suction grill 310 is completed.

On the other hand, in order to lift the air conditioner as described above, the user must lift the hand into the pair of handles 340. At this time, it is preferable to lift in front of the air conditioner as described above. That is, since the inner space of the handle 340 is gradually wider toward the rear side, it is preferable that the human perception (second finger) is located at the inner rear end of the handle 340.

In addition, in order to assemble the handle 340 to the handle hole 342 is possible by applying a force in close contact with the handle 340 on both sides. That is, since the fixed rib 348 of the handle 340 is formed on one side (inner side) is inclined to form a guide surface 348 ", when the handle 340 is pushed into the handle hole 342, The guide surface 348 "is to slide while contacting the edge of the handle hole 342.

Therefore, when the force is continuously applied in the side (inner side) in this state, the fixed rib 348 finally moves to the inside of the handle hole 342, the side of the rear frame 300 is the handle 340 Is located in the handle groove (349). In this case, the mounting of the handle 340 is completed.

In addition, in order to mount the front panel 200 to the front frame 100, the front panel 200 is first coupled to the front frame 100 by the provisional assembly means described above, and then the fixing described above. Secure it completely by means.

In more detail, first, the front panel 200 is in close contact with the front of the front frame 100, the plurality of panel hooks 220 are inserted into the plurality of panel hook holes 130 and the front panel ( 200 is temporarily assembled.

Then, a fastening member, such as a screw, passes through the panel fastening hole 132 ′ of the panel fastening portion 132 from the rear side of the rear frame 300, and then the fastening member is fastened to the panel fastening protrusion ( When screwed to 222, the front panel 200 is completely fixed to the front frame (100).

In addition, when the front panel 200 is heavy, the front panel 200 may be more firmly fixed to the front frame 100 by using the above-described additional fastening means. Same as the fastening process of the means.

Next, with reference to Figure 18 looks at the condensate flow in the upper surface of the main drain pan 700. In the second heat exchanger 860, heat exchange occurs between the external air and the internal refrigerant, and in this process, water in the air condenses to generate condensed water.

The condensed water generated in this process descends to the lower portion of the second heat exchanger 860 and falls on the upper surface of the main drain pan 700. The condensed water dropped on the upper surface of the main drain pan 700 is guided and flows by the bottom compartment rib 702, and passes through the main drain pan 700 through the bottom condensation water hole 704 in the process. Will be moved to.

Meanwhile, the condensed water on the upper surface of the main drain pan 700 also flows into the housing seating groove 710. That is, since the housing seating groove 710 is formed at a position lower than the upper surface of the main drain pan 700, some of the condensate moves to the housing seating groove 710.

The condensed water moved to the housing seating groove 710 is guided by the groove compartment rib 712, and gradually moves to the lower portion of the housing seating groove 710. Then, it moves downward through the groove condensation water hole 714 formed at the lowermost end of the housing seating groove 710.

The condensate that has passed through the condensate holes 704 and 714, ie, the bottom condensate water hole 704 and the groove condensate water hole 714, and moves to the lower side of the main drain pan 700 is taken along the inner surface of the condensate drop guide 716. It flows down, and then forms a lower end of the condensate drop guide 716 and then falls downward. The condensate falling from the condensate drop guide 716 drops onto the upper surface of the auxiliary drain pan 750.

25 and 26 are perspective views illustrating an installation state of various components installed in the main drain fan 700.

On the other hand, as described above, the refrigerant pipe 746 is passed up and down through the pipe passage groove 726, the work tool 724 is located above the compressor 520. Therefore, when a protective cap (not shown) is to be mounted on the compressor 520, the operator can insert the protective cap from the upper side through the work tool 724.

In addition, the duct avoiding groove 722 is located above the exhaust guide 650. Therefore, although not shown, when the lower end of the exhaust guide means 400 is installed in connection with the exhaust guide 650, the first half of the exhaust guide means 400 is accommodated in the duct avoiding groove 722 will be.

Therefore, in this case, the coupling member such as a screw is fastened through the soft exchange coupling parts 780 and 782, so that the auxiliary drain pan 750 and the upper end of the first heat exchanger 510 are coupled to each other. In this case, since the upper right side of the first heat exchanger 510 is in contact with the heat exchange support rib 784, the first heat exchanger 510 is prevented from falling to the right side.

On the other hand, the plurality of orifice tightening ribs 786 is inserted into the orifice fastening hole (not shown) formed in the lower orifice 600, thereby the auxiliary drain pan 750 and the lower orifice 600 Combined with each other.

The upper end of the condensate pipe 560 is fastened to the connector fastening portion 768 of the auxiliary drain pan 750. Therefore, the condensate accumulated in the base pan 500 is pumped by the condensate pump 550 and is introduced into the auxiliary drain pan 750 through the condensate pipe 560.

The condensed water supplied to the auxiliary drain pan 750 through the condensate pipe 560 flows into the drain guide surface 760 and is guided by the drain guide groove 762 to the bottom of the auxiliary drain pan 750. It flows to the surface 750a. In addition, at this time, the condensed water collected in the main drain pan 700 also falls to the bottom surface of the auxiliary drain pan 750.

Thus, since the bottom surface 750a is inclined, the condensed water dropped to the bottom surface 750a of the auxiliary drain pan 750 moves to the drop hole 752, passes through the auxiliary drain pan 750, and then The drop guide rib 754 is reached, and falls from the drop guide rib 754 and flows down along the right portion of the first heat exchanger 510.

In addition, the condensed water flowing along the right portion of the first heat exchanger 510 is introduced into the heat generated by the first heat exchanger 510 and the lower grill 330, and thus the first heat exchanger 510. Evaporated by air passing through
