An electrical power cord arrangement for a room air conditioner of the type having an indoor section, an outdoor section, an electrical control box contained within the indoor section and an outer housing partially enclosing both sections. The outer housing has an access opening therein in the region thereof which encloses the outdoor section. An electrical power cord having a first end, which terminates within the electrical control box extends from the control box, through the housing, into the outdoor section of the air conditioner where it then passes from the housing through the access opening to the exterior thereof, where it terminates in a second end configured to be connected to a source of electrical power.

Room air conditioner having outdoor power cord

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

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 shipping protector is provided which is to be disposed between a substantially rectangular article and a shipping container for the article. The article is of the type having a base having four base corners and a top having four top corners, each of which is in substantially vertically spaced relationship with one of the base corners. The protector includes a base support configured to engage the article's base and each of the base corners. The base support has a thickness sufficient to define an upwardly facing surface adjacent each of the base corners. A first top support is provided which is configured to engage two of the top corners and which has a downwardly extending structural section adjacent each of the corners. The structural sections have a length sufficient to allow the lower ends thereof to engage the upwardly facing surface associated with one of the base corners. A second top support, similar to the first, is configured to engage the other two of the top corners and has similarly configured downwardly extending structural sections. As a result, with the base support and the first and second top supports engaging the article to be shipped while in the shipping container, vertical forces applied to the container will be reacted to the top supports and will be transferred through the downwardly extending sections to the base support.
