The front section also includes an opening configured to provide access to the air conditioning unit's control box when the grille is mounted on the indoor unit. The control box access opening is substantially rectangular and is surrounded by three outwardly facing fixed wall sections, each of which is substantially coplanar with the front section. A fourth fixed wall section lies in a plane behind the front section of the grille. An insert is provided, which has a back section and a front wall. The front wall is configured to be coplanar with each of the three fixed wall sections when the back section of the insert is placed in confronting relation with the fourth fixed wall section.

Abstract: A front grille for a room air conditioning unit includes a planar front section, which includes an air inlet opening, an air outlet opening, and an opening configured to receive the unit's control panel when mounted on an air conditioning unit. The front section has a top wall, bottom wall, and left and right-hand side walls, each of which extend rearwardly of the front section and cooperate with one another to define a skirt element integrally formed with and extending rearwardly from the planar front section. An elongated recess is formed in the planar front section. One or more inserts, each of which is configured to be received in the recess in the front section, are provided. Each of the inserts has a distinguishing ornamental configuration thereon, which is different from the distinguishing ornamental configuration of the other inserts. Means are provided in the elongated recess and on each of the inserts for cooperating with one another to retain each of the inserts in the recess.
