AI Technical Summary

Technical Problem

Air conditioners with ceiling panels suffer from crazing due to adhesion of oil or detergent, leading to cracks and damage at screw attachment points, as outside air enters through gaps and causes chemical changes in the resin, reducing the lifespan and aesthetic appearance.

Method used

An air conditioner design featuring a panel with a panel air suction port positioned to overlap the air suction port, an attachment portion with a protruding wall and a lid portion that locks to seal the screws, preventing adhesion of oil or detergent and thus suppressing crazing and damage.

Benefits of technology

The design effectively isolates the attachment part from outside air, preventing crazing and subsequent cracking, thereby extending the lifespan and maintaining the aesthetic appearance of the ceiling panel.

Abstract

An air conditioner which suppresses crazing of an attachment portion for screws in a panel attached to an indoor unit using the screws and suppresses cracking and damage of the panel is provided. The air conditioner includes the indoor unit that suctions air from an air suction port and blows out the suctioned air from an air blowout port through an indoor heat exchanger, the panel that is attached to the indoor unit and has a panel air suction port at a position where at least a portion of the panel overlaps the air suction port, and a lid portion. The panel includes an attachment portion that is provided around the panel air suction port and to which screws for fixing the panel to the indoor unit are attached. The lid portion covers the screws and seals the attachment portion.
