However, in the panel structure of the air conditioner described above, when the lowermost suction panel is attached to the center panel, the lower portion (lower frame portion) is first engaged with the case. However, the suction panel itself is twisted or distorted, causing a displacement between the upper portion (upper frame portion) of the suction panel and the center panel. In other words, the suction panel is positioned on both sides of the center panel. There is a problem that both sides are displaced, and the positions of the engaging pieces of the center panel and the locking claws of the suction panel do not easily match, so that the suction panel cannot be easily attached.

Further, if the suction panel is attached while being twisted with respect to the side portion of the case or the center panel, misalignment occurs with respect to the casing and the center panel, resulting in poor appearance.

In particular, since the suction panel is usually located at the lowermost portion of the front panel, it is desired that the suction panel can be easily attached even by groping operation.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an air conditioner in which a panel can be easily mounted even by groping, and which has a good appearance after the panel is mounted.

[0009]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a case where a plurality of panels are sequentially arranged along a longitudinal direction of an opening of a case in which a heat exchanger, a blower and the like are stored, and the opening is closed. A first positioning means for positioning both sides of the one of the plurality of panels at a side surface of the opening of the case; and a panel positioned between the two sides. And second positioning means for positioning the side of the panel with respect to the side of the other panel of the plurality of panels.
When closing the case opening with
Fix the panels and place both sides of one panel in the first position.
The second position while guiding it to the side of the case
Means to connect the side of one panel to the side of the other panel.
It is characterized in that it is configured to be guided to .

[0010]

In the air conditioner of the present invention, the other panel is attached, and then one panel is detachably attached.
When one panel is mounted, first positioning means for positioning both sides of the panel with respect to the side of the case guides both sides of one panel, and second positioning means for positioning with respect to the side of the other panel. Therefore, even if groping, displacement of one panel and twisting can be prevented, and the panel can be easily attached.
