- the extension 18 a shields the gap between the suction port 17 and the suction grille 18 while looking up at the suction grille 18.
- the joint between the suction grille 18 and the panel body 3A is not able to feel the force at the stepped portion 60, and the suction grille 18 becomes extremely thin and has an image to improve the appearance. .
- the gap between the suction port 17 and the suction grille 18 becomes substantially narrow, and air is hardly sucked from this gap. That is, the amount of air that does not pass through the filter attached to the suction grill 18 is reduced, and the dust trapping efficiency of the filter can be improved.
- design options can be increased, and the corner panel can be attached and detached without being affected by the installation location.
