FIG. 1 is an exploded perspective view showing the main structure of an integrated air conditioner according to the prior art.

As shown in FIG. 1 , the internal structure of the integrated air conditioner is as follows: a chassis 130 constitutes the bottom surface of the air conditioner. A front grille 20 is provided on the indoor front of the chassis 130 . The above-mentioned front grille 20 constitutes the front appearance of the air conditioner. More specifically, the above-mentioned front grille 20 is mounted on the front of the casing 140 which will be described below.

One side of the front grille 20 is formed with a suction portion for sucking the air in the space to be air-conditioned into the inside of the air conditioner. The other side is formed with a discharge part that discharges the air that has completed the heat exchange inside the air conditioner to the room again. In addition, a suction grill 10 is provided on the suction portion. Then, one side of the discharge part is provided with a control box 120 for operating the state of the air conditioner.

An indoor heat exchanger 30 is provided inside the front grille 20 . The function of the indoor heat exchanger 30 is to exchange heat between the air sucked through the suction part of the front grille 20 and the working fluid in the air conditioning system. More specifically, the indoor heat exchanger 30 is provided on an air guide 40 which will be described below.

Here, the structure of the air guiding device 40 provided with the indoor heat exchanger 30 is as follows: In the central part of the air guiding device 40 , a through hole for guiding the air passing through the indoor heat exchanger 30 is formed.

The bottom surface of the air guiding device 40 is formed with a drainage device for discharging condensed water generated in the indoor heat exchanger 30 . Then, the bottom surface of the above-mentioned air guiding device 40 is further provided with: a scroll casing 60 combined with the above-mentioned air guiding device 40 . Then, the inner surface of the above-mentioned scroll case 60 is formed with a flow guide surface so as to guide the airflow formed by the indoor blower fan 80 which will be described below.

In addition, the discharge part side of the said front grille 20 is provided with the control box 120 which accommodates the electronic component for controlling an air conditioner inside.

Then, a partition plate 70 for separating the indoor side part and the outdoor side part of the air conditioner is provided in close contact with the rear surface of the scroll case 60 . The function of the partition 70 is to separate the indoor part and the outdoor part of the air conditioner, so that the indoor environment and the outdoor environment will not be affected by each other.

Moreover, at the rear end of the partition 70 , that is, on the outdoor side: the motor fixing frame 90 is installed on the chassis 130 , and then the motor 100 is arranged on the motor fixing frame 90 . The shafts of the motor 100 protrude from the indoor side and the outdoor side respectively, and the shafts on one side pass through the partition plate 70 and protrude into the scroll housing 60 on the indoor side. Here, an indoor ventilation fan 80 is provided on the motor shaft protruding to the indoor side. The function of the above-mentioned indoor blower fan 80 is to suck the air in the space that needs to be air-conditioned, make it pass through the above-mentioned indoor heat exchanger 30, and then discharge the air into the room again.

Then, an outdoor blower fan 110 is arranged on the outdoor side shaft of the motor 100 . The function of the above-mentioned outdoor blower fan 110 is to suck in outdoor air and make the air pass through the outdoor heat exchanger 170 outside the air conditioner room for heat exchange. Moreover, the said outdoor side is provided with the cover 150 which guides the airflow by the said outdoor ventilation fan 110. As shown in FIG. The function of the cover 150 is to evenly transmit the air sucked in from the outside to the outdoor heat exchanger 170 . Here, the central portion of the cover 150 is formed with a through hole for installing the outdoor fan 110 .

Reference numeral 160 is: a cover cap forming the top of the cover 150 . In addition, reference numeral 180 is a brace that connects the above-mentioned scroll case 60 and the upper end of the cover cap 160 to secure the installed state.

In addition, the outdoor heat exchanger 170 is disposed on the chassis 130 , that is, disposed on the outermost side of the outdoor side. The outdoor heat exchanger 170 enables heat exchange between the air sucked in from the outside and the working fluid.

In addition, the present invention is further provided with: a casing 140 that seals the interior to protect various components provided on the chassis 130 . Here, the casing 140 is connected and fixed on the chassis 130, so as to close the two sides and the upper end of the air conditioner.

Then, a compressor (not shown in the figure) and an expansion valve (not shown in the figure), etc., which are important components of the air conditioning system, are also arranged on the outdoor side.

In the integrated air conditioner having the above-mentioned structure: the part corresponding to the indoor side is installed facing the room, so as to be used in a space requiring air conditioning; and the part corresponding to the outdoor side is installed facing the outside.

That is, the all-in-one air conditioner having the above structure is inserted into the mounting hole formed on the wall. At this time, a wall sleeve (not shown in the figure) has been provided in advance on the inner side of the above-mentioned installation hole, and a louver-grille (louver-grille) (not shown in the figure) is finally provided behind it. Here, outside air on the outside of the house will be drawn in and exhausted through the aforementioned louvered grilles.

Then, in order to firmly install the above-mentioned integrated air conditioner in the wall sleeve, various auxiliary fixing members are used on the back side and trim (not shown) members are used on the front side.

The cooling function of the air conditioner is as follows: once the air conditioner is driven, the air conditioning system will start to run, and the motor 100 will drive the indoor air supply fan 80 and the outdoor air supply fan 110 to run. Therefore, on the indoor side, the air in the space requiring air conditioning is transferred to the indoor heat exchanger 30 through the suction portion of the front grill 20 .

At this time, when the above-mentioned sucked air passes through the indoor heat exchanger 30, it exchanges heat with the working fluid, and becomes relatively low in temperature. Through the rotation of the above-mentioned indoor blower fan 80, the above-mentioned air that has completed the heat exchange will pass through the through hole of the above-mentioned air guiding device 40, and after being sucked into the indoor blower fan 80, it flows along the inside of the scroll casing 60, and finally passes through the front surface. The discharge portion of the grill 20 is discharged to a space requiring air conditioning.

In addition, on the outdoor side, the working fluid discharges the heat transferred in the indoor heat exchanger 30 to the outside. That is, outside air is sucked into the outdoor side of the air conditioner by the outdoor fan 110 , guided by the cover 150 , exchanges heat with the working fluid through the outdoor heat exchanger 170 , and finally discharges heat to the outside.
