An improved room air conditioner of the type having an indoor section and an outdoor section, which are supported by a basepan and which are separated by a partition. The indoor section includes an indoor fan and an evaporator coil and the outdoor section includes a condenser coil, an outdoor fan and a compressor. The air conditioner is made from two subassemblies, the first subassembly includes a basepan having an indoor region near the front of the basepan and an outdoor region near the back of the basepan. The compressor is supported in the outdoor region and a condenser coil is also supported in the outdoor region rearwardly of the compressor. The evaporator coil is supported in the indoor region and a refrigeration flow circuit interconnects the condenser, the evaporator coil and the compressor. The second subassembly includes a vertically extending partition having an indoor side, an outdoor side and an opening therethrough extending from one side to the other. The partition is configured to cooperate with the basepan to separate the indoor region from the outdoor region. An electric motor is mounted on the outdoor side of the partition. The motor has a drive shaft extending perpendicular to the partition with the first end extending through the opening so that it is on the indoor side of the partition and the second end on the outdoor side of the partition. An indoor fan is mounted to the first end of the drive shaft and an outdoor fan is mounted to the second end of the drive shaft. The second subassembly is configured to be assembled to the first subassembly by positioning the second subassembly in a position vertically spaced above the first subassembly and lowering it into alignment with the first subassembly with the outdoor fan forward of and adjacent to the outdoor heat exchanger, and the indoor fan rearward of and spaced from the indoor heat exchanger. The partition engages the basepan and is structurally attached thereto.

Window room air conditioner

A front grille for the indoor section of an air conditioning unit includes a substantially planar front section, which has air inlet louvers and an air outlet opening formed therein. 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. Structure is provided for removably attaching the insert to the grille to retain the insert to the back section in the aforementioned confronting relation. The insert may be a narrow insert having a width, which is substantially comparable to that of the three wall sections or, alternatively, may be configured to substantially completely overlie the opening. When the insert is configured to substantially completely overlie the opening, the structure for removably attaching the insert is configured to allow the insert to pivot between a position overlying the opening and a second position where it does not overlie the opening.

Control box door/fairing for front grille of an air conditioner

An air conditioner is provided of the type having an indoor section, which includes a housing, evaporator coil and an indoor grille adapted to be mounted to the housing in spaced relation to the evaporator coil. The grille includes a front wall having a return opening therein to admit return air to be conditioned into the evaporator coil. The front wall also has an elongated opening adjacent to an edge thereof, which is adapted to receive a filter for insertion and removal of the filter into the space between the back wall of the indoor grille and the evaporator coil. The filter includes a rectangular frame having a leading edge and a trailing edge and laterally spaced edges interconnecting the leading and trailing edges. A filter guide structure is integrally formed with the grille and is adapted to receive the leading edge of the filter with the filter frame angularly disposed with respect to the front wall and for directing the rectangular frame into the space between the back wall of the indoor grille and the evaporator coil without contacting the evaporator coil. In a preferred embodiment, the trailing edge defines an ornamental outer wall similar in configuration to the structure defining the return air openings in the front wall of the grille. Structure is provided on the ornamental outer wall and the filter guide structure for supporting and positioning the outer wall with respect to the outer grille structure.

Air filter inlet and positioning guide for an air conditioner

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.

Air conditioner front grille with inserts for brand differentiation

A control box for an air conditioning unit, which is configured to contain control components and a capacitor. The control box includes a housing having an inverted L-shape, which defines a substantially vertical section and a substantially horizontal section. The horizontal section has an open front defined by peripherally extending edges. One or more of the edges are provided with attachment structure integrally formed thereon. A control panel section for housing the control components has an open back defined by a plurality of peripherally extending edges. The edges of the control panel section are configured to engage the edges of the horizontal section and are provided with attachment structure formed thereon which is configured to cooperate with the attachment structure of the horizontal section to thereby facilitate attachment of the control panel to the horizontal section.
