Hereinafter, the operation of the indoor unit of the air conditioner as described above.

First, look at the operating state when the indoor unit 100 is used for cooling the space for air conditioning.

The indoor unit 100 having the above configuration is generally used in an upright state as shown in FIG. 8, in which air is introduced into the indoor unit 100 from below through the inlet 210. That is, when the indoor fan 332 is rotated by the power applied from the outside, a suction force is generated, and the air from the outside (the space for air conditioning) is caused by the suction force through the suction port 210 to the indoor unit 100. Is sucked into the interior.

The air introduced into the interior through the inlet 210 is first filtered by the air filter 222, and then heat exchange occurs while passing through the indoor heat exchanger 250. That is, when the air conditioner is operated to cool, the indoor heat exchanger 250 acts as an evaporator, so that the air sucked through the inlet 210 deprives heat of the refrigerant flowing inside the indoor heat exchanger 250. Will be.

Meanwhile, when heat exchange occurs through the indoor heat exchanger 250, condensed water is generated in the indoor heat exchanger 250 due to a temperature difference, and the condensed water descends downward and is collected in the drain pan 230. The condensed water dropped to the drain pan 230 is transferred to the tip portion and discharged to the outside of the indoor unit 100 through the drain portion 232.

Air deprived of heat while passing through the indoor heat exchanger 250 is introduced into the indoor fan 332 through the side of the fan housing 336 and then discharged in the circumferential direction. The air discharged in the circumferential direction by the indoor fan 332 is guided by the fan housing 336 and discharged upward through the discharge port 340.

The air discharged through the discharge port 340 of the fan housing 336 is external (air) through the discharge port 170 formed by the exhaust guide member 350 and the vertical guide part 320 of the upper frame 300. Space for coordination). Of course, although not shown at this time, a separate connection duct is further installed between the discharge port 170 and the space for air conditioning to guide the air.

Although not shown, the outdoor heat exchanger inside the outdoor unit installed in a separate space while the indoor unit 100 is operated as described above serves as a condenser. Therefore, since the refrigerant inside the outdoor heat exchanger emits heat into the air, the indoor unit 100 and the components of the outdoor unit form one cycle as a whole.

Next, look at the case where the indoor unit 100 is used for heating. At this time, the indoor heat exchanger 250 acts as a condenser by reversing the flow of the refrigerant (working fluid) flowing inside the indoor heat exchanger 250 or by simply operating the electric heater 360 to heat air. Done.

Looking at the case of heating using the electric heater 360, the air of the outside (space for air conditioning) is introduced into the indoor unit 100 through the suction port 210 in accordance with the rotation of the indoor fan 332. Then passes through the indoor heat exchanger (250).

At this time, since the indoor heat exchanger 250 is in an inoperable state, heat exchange is not performed, and the sucked air moves upward and flows into the indoor fan 332 through the side of the fan housing 336. . The air forcedly blown by the indoor fan 332 is guided upward by the fan housing 336 to pass through the exhaust guide member 350.

At this time, since the electric heater 360 is heated by the power applied from the outside, the air passing through the exhaust guide member 350 is heated by the electric heater 360, the hot air is discharged 170 It is discharged to the indoor space (space for air conditioning) through. This realizes the heating of the indoor space.

Meanwhile, the indoor unit 100 as described above needs to be installed upside down as necessary. As such, when the indoor unit 100 is installed inverted, the installation state of the indoor heat exchanger 250 and the drain pan 230 must be changed as shown in FIG. 9 in order to process the condensed water generated in the indoor heat exchanger 250. do.

That is, as shown in FIG. 8 (upright state), the indoor heat exchanger 250 and the drain pan 230 installed at the lower end of the indoor unit 100 are pulled forward and separated, and then the indoor unit 100 is turned upside down. Upright, the indoor heat exchanger 250 and the drain pan 230 is installed on the center frame 260.

In addition, the front lower panel 120 is also removed and mounted upside down like the indoor heat exchanger 250. In this case, the drain portion 232 of the drain pan 230 is exposed to the outside through the drain hole 124 of the front lower panel 120 as in the case where the indoor unit 100 is upright.

On the other hand, when the drain pan 230 and the indoor heat exchanger 250 is mounted on the upper surface of the center frame 260 as described above, the rear end of the drain pan 230 is raised to the front end of the center frame 260. Then, when the drain pan 230 is pushed backward, both ends of the drain pan 230 slide in a state where it is mounted on the upper surface of the fan guide guide 256 of the center frame 260 and is pushed back.

As shown in FIG. 9, the indoor heat exchanger 250 and the drain pan 230 are mounted upside down. Referring to the operation state of the indoor heat exchanger 250 and the drain pan 230, the external heat exchanger 250 and the drain pan 230 are installed in an upright state. First, the indoor fan 332 rotates.

As the indoor fan 332 rotates, air from outside (indoor space or space for air conditioning) is sucked into the indoor unit 100 from the upper portion through the suction port 210. The air sucked through the suction port 210 passes through the indoor heat exchanger 250 and exchanges heat with the refrigerant therein to become cold air.

At this time, the surface of the indoor heat exchanger 250 generates condensate during heat exchange, and the condensate is collected in the drain pan 230 which is integrally installed at the lower portion. In this case, the condensed water accumulated in the drain pan 230 is discharged to the outside (front) through the drain portion 232 of the tip portion.

Meanwhile, the air passing through the indoor heat exchanger 250 descends downwardly and flows into the indoor fan 332 through the side of the fan housing 336, and the air introduced into the indoor fan 332 is circumferentially directed. Discharged and discharged downward through the discharge port 170. In addition, a connection duct (not shown) may be further installed at the discharge port 170, and the connection duct may guide the air discharged to the discharge port 170 as a space for air conditioning.

The scope of the present invention is not limited to the above-exemplified embodiments, and many other modifications based on the present invention will be possible to those skilled in the art within the above technical scope.

In the indoor unit of the air conditioner according to the present invention as described in detail above, the front panel was divided into upper and lower panels, and the front upper panel and the front lower panel were configured to have symmetrical shapes.

Therefore, when the indoor unit is installed upside down, since the front lower panel may also be installed upside down, there is an advantage of easy installation of the indoor unit.

In addition, in the present invention, since the front lower panel is installed upside down when the indoor unit is inverted, it is not necessary to additionally form a separate drain hole for the indoor unit inverted. In other words, in the prior art, an additional drain hole may be additionally formed in the front lower panel in preparation for the inverted installation of the indoor unit. However, in the present invention, since the front lower panel is installed upside down, there is no need to install an additional drain hole. .

Therefore, according to the present invention, there is an effect of reducing the work maneuver required for the formation of additional drain holes, there is an effect that the heat insulation is improved due to the reduced number of drain holes.
