That is, when the indoor unit 100 does not directly contact the space for air conditioning, a connection duct (not shown) connecting the indoor unit 100 and the space for air conditioning includes the inlet 210 and the outlet 170. It is installed in).

In addition, as shown in Figure 5, the inner surface of the outer case (100 ') is further provided with a heat insulating member 380 to insulate the outside, the support means for the heat insulating member 380 is in close contact with the outer case Phosphorus insulation fixing member 382 is further installed in the center portion.

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 configuration as described above is generally used in an upright state as shown in FIG. 3, wherein air is introduced into the indoor unit 100 from below through the suction port 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 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 between the discharge port 170 and the space for air conditioning is further installed 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. In the heating mode, 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. Will be heated.

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.

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.

As described in detail above, in the indoor unit of the air conditioner according to the present invention, the triplet is formed of a plurality of holes (Hole) having different outer diameters so that wires are connected to one side of the side panel and one side of the top panel that form the side and top exteriors. Is configured to form a plurality of wire connectors.

Therefore, by selecting the wire connector of the appropriate size according to the amount of power consumed in the indoor unit is expected to minimize the loss of air flow caused by the gap of the wire connector to maximize the efficiency of the air conditioner.

In addition, since the size of the wire connector can be diversified, an appropriate size of the wire connector can be selected in response to the thickness of the wire according to the power consumption, thereby preventing insulation breakdown or electrical leakage, thereby increasing the electrical safety.

In addition, by forming the wire connector on the side and top panel can be connected to the power in the most convenient position according to the installation state of the indoor unit (when installed upright and horizontally installed) is expected to be easy to install the indoor unit.
