Therefore, even if the cooling operation is performed for a long time, it is relatively difficult for dew to condense on the front surface portion on the outlet side.

[0004]

In such a conventional air conditioner, the heat transfer from the dew tray where the cold water condensed in the heat exchanger accumulates cools the front end of the front panel. Remains, and there is a demand for less heat transfer from the dew tray to the front side of the front panel.

Further, in terms of structure, it is necessary to fix the shield plate to the locking rail by welding or the like, and there is a problem that accurate positioning is difficult. Therefore, the locking rail and the shielding plate may be integrated. Is required.

Further, when dew condensation occurs on the top panel or the blowout grill from the clearance near the air outlet of the front panel, the dew condensation water may not be surely collected. Therefore, the dew condensation water may be more reliably collected in the dew tray. Required to do so.

The present invention solves such a conventional problem by reducing the heat conduction from the dew tray to the front side of the front panel, and also when the dew condensation occurs on the top panel and the outlet grill. It is an object of the present invention to provide an air conditioner that can reliably collect the debris in the dew tray and that can reliably obtain the shielding effect by integrally forming the locking rail and the shielding plate.

[0008]

In order to achieve the above-mentioned object, an air conditioner of the present invention has a substantially rail-shaped locking rail provided in the vicinity of an outlet of an air conditioner body, and a front surface that covers the front surface of the body. The panel is provided at an end portion of the panel and has a substantially hook-shaped tip, and the locking means for engaging with the locking rail is configured to come into contact with each other in a line contact structure.

According to the present invention, an air conditioner in which dew condensation on the front side of the front panel is prevented by reducing heat conduction from the dew tray and other peripheral components to the front side of the front panel can be obtained.

In addition to the above-mentioned means, a blowing shield plate is provided near the blowing grill so as to shield the lowermost stage of the substantially L-shaped blowing grill.

According to the present invention, it is possible to obtain an air conditioner in which dew condensation on the front side of the front panel is prevented by not directly applying cold air to the front panel.

Further, a blowout grill is provided at a position recessed from the woven surface of the top panel and the front panel forming the outer casing of the air conditioner body, and a drainage hole is provided in a locking rail near the blowout grill, and the blowout grill is provided on the blowout grill. The ridgeline woven between the adjacent top panel surface and the fitting contact surface of the blowout grill is formed by a gently curved surface.

According to the present invention, it is possible to obtain the air conditioner which can surely collect the water condensed on the top panel and the blowout grill to the dew tray.
