The air heat-exchanged in the heat exchanger 170 becomes air of a relatively low temperature and is sucked into the cross flow fan 174. The air sucked into the cross flow fan 174 is discharged in the circumferential direction of the cross flow fan 174 and then guided downward.

The air guided downward passes through the discharge passage 182 of the discharge grill 180, and the discharge direction is controlled by the vanes 184 and the louver 186 installed inside the discharge passage 182. It is discharged to the space for air conditioning.

Hereinafter, a process of installing the indoor unit 100 on the wall surface of the indoor space using the mounting plate 200 will be described with reference to FIGS. 6A to 7B. And, since the installation of the indoor unit is substantially the same as the combination of the main chassis 110 and the mounting plate 200 to replace the installation process of the indoor unit 100 by the process of combining the main chassis 110 and the mounting plate 200. Shall be.

6a to 6c is a longitudinal cross-sectional view showing in sequence the process of the installation plate 200 and the main chassis 110, which is a main component of the indoor unit of the air conditioner according to the present invention, Figures 7a to 7b is in the present invention Air conditioner by the indoor unit is an installation state schematically showing the appearance of the indoor unit installed on the right or left side of the wall surface.

First, after selecting the position to install the indoor unit to adjust the position of the step portion 260 close to the edge of the wall, and then a fixing member such as a nail or screw is inserted into the fixing hole 222 to be fixed to the wall surface. .

When the fixing member is fixed to the wall through the fixing hole 222, as shown in Figure 7a and 7b, the rear surface of the mounting plate 200 is fixed while maintaining the state in contact with the wall.

Thereafter, the main chassis 110 is inserted into the mounting plate 200 to insert the insertion protrusion 116 into the restraint hole 244. More specifically, in the state in which the lower end of the insertion protrusion 116 is lifted to be located higher than the upper surface of the support piece 242, the position of the insertion protrusion 116 and the restriction hole 244 is aligned in a straight line. The main chassis 110 is lowered downward so that the insertion protrusion 116 and the restriction hole 244 are locked.

When the insertion protrusion 116 is inserted into the restraint hole 244, the main chassis 110 is constrained by the mounting plate 200 so as not to fall.

Thereafter, the lower part of the main chassis 110 is pushed to the right. In this case, the main chassis 110 is rotated in the counterclockwise direction with respect to the restraint hole 244, and the fitting protrusion 118 is inserted into the insertion hole 247 to be in contact with the hook 248. .

When the lower portion of the main chassis 110 rotates in the counterclockwise direction to approach the right side surface of the installation plate 200, the upper end of the hook 248 is accommodated in the locking groove 118 ′. The hook 248 accommodated inside the locking groove 118 ′ is in contact with the right inner surface of the locking groove 118 ′ to limit interference with the left side of the main chassis 110.

At the same time, the lower surface of the main chassis 110 is in contact with the upper surface of the support piece 242 formed at the lower end of the mounting plate 200, a portion of the load of the main chassis 110 by the support portion 240 Supported (see FIG. 7C).

As described above, the main chassis 110 and the mounting plate 200 are not separated from each other when the insertion protrusion 116 is inserted into the restriction hole 244 and the hook 248 is inserted into the locking groove 118 '. Will not.

And, even if the position where the stepped portion 260 is located on the right or left side of the wall as shown in Figs. 7a and 7b, since the configuration and process that the main chassis 110 is coupled to the mounting plate 200 is the same A separate description of the operation will be omitted.

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

In the indoor unit of the air conditioner according to the present invention as described above, a part of the front surface of the mounting plate fixed to the wall surface of the indoor space and supporting the indoor unit is formed to be inclined.

Therefore, the air discharged from the indoor unit can flow to the center of the indoor space without hitting the wall, and the heat exchange efficiency is improved.

In addition, there is an advantage that can be installed in a variety of locations with a single mounting plate by rotating the mounting plate according to the installation position of the indoor unit.

In addition, the user is expected to improve the product satisfaction by solving the conventional complaints about local area cooling / heating.
