A molded plastic basepan supporting components of a room air conditioner includes a substantially rectangular bottom wall having a front edge, a back edge and left and right side edges. The bottom defines a top surface and bottom surface, and each of the edges thereof includes a structural side wall section extending upwardly therefrom in a direction substantially perpendicular to the bottom wall. A vertically extending substantially hollow structural beam is formed in the bottom wall of the basepan. The structural beam extends laterally from a location proximate the left side wall to a location proximate the right side wall. In a preferred embodiment, the bottom surface of the bottom wall is substantially planar and the structural beam is defined by a closed elongated channel extending upwardly into the basepan to define an elongated enclosed wall extending upwardly from the top surface of the bottom wall.

Molded plastic basepan for a room air conditioner

A condensate drain arrangement for an air conditioner, which includes a molded plastic basepan having a substantially horizontally extending bottom wall. The bottom wall has an outdoor section which includes a region for collecting condensate therein. A first condensate drain is formed in the basepan in fluid communication with the condensate collecting region. The first condensate drain is configured to conduct substantially all of the condensate collected within the region for collecting from the basepan. The first condensate drain is optionally enabled by the user of the air conditioner. A second condensate drain is also formed in the basepan in fluid communication with the region for collecting condensate. The second condensate drain is configured to allow collection of condensate in the collection region to a predetermined depth and to conduct condensate which would exceed said predetermined depth from the basepan. The second condensate drain is also optionally enabled by the user of the air conditioner. In a preferred embodiment, a condensate collector is configured to be mounted in the air conditioner housing to collect condensate from whichever of the condensate drains has been enabled. The condensate collector has a single outlet therefrom for conducting condensate to a desired disposal location.

Condensate drain arrangement for an air conditioner

A room air conditioner of the type having a chassis configured to be removably received in an outer housing. The chassis includes a basepan having an indoor region proximate the front of the basepan and an outer region proximate the back. The chassis further includes a condenser coil supported in the outdoor region. The condenser coil has a support structure including an upper portion overlying the upper end of the condenser coil. The chassis further includes a partition supported at its lower end by the basepan and configured to separate the indoor and outdoor regions. The upper end of the partition is configured to be in close proximity to the interior of the outer housing when the chassis is received therein. The outer housing defines a substantially rectangular structure having a lower section configured to receive and support the basepan thereupon. Vertically extending side walls extend from left and right sides of the lower section and a top wall extends between the upper ends of the side walls.

Structure for facilitating assembly of an air conditioning unit having a removable chassis

An improved room air conditioner of the type assembled from a first subassembly, which includes a basepan having an indoor region proximate the front of the basepan and an outdoor region proximate the back of the basepan. A compressor, a condenser coil, an evaporator coil, and a refrigeration flow circuit are all included in the first subassembly. A second subassembly includes a vertically extending partition having an indoor side, an outdoor side and an opening therein extending from the indoor side to the outdoor side. The partition is configured to cooperate with the basepan to separate the indoor region from the outdoor region. The second subassembly includes an electric motor mounted on the partition, which is adapted to drive an indoor fan and an outdoor fan. The first and second subassemblies are configured such that they may be assembled separate from one another and may be assembled to one another by the positioning of the second subassembly in a position vertically spaced above the subassembly and lowering the second subassembly into a predetermined alignment with the first subassembly with the partition engaging the basepan. The partition is provided with a vertically extending lower portion defining a lower edge. The basepan defines a lower wall having formed therein an upstanding structural wall, configured to receive the lower portion of the partition in confronting relation therewith with the lower edge of the partition in contact with the lower wall.

Air conditioner structure

A control for an air conditioning unit, which is configured to be easily attached to a vertically extending partition of the air conditioning unit. The control box includes a main housing having a substantially horizontal bottom wall. The bottom wall has front, side and rear edges and a front wall extending substantially vertically upwardly from the front edge of the bottom wall. A side wall extends substantially vertically upwardly from each of the side edges of the bottom wall. Each of the side walls has a front edge integrally formed with the front wall and a rear edge having a downwardly extending attachment hook extending rearwardly of the rear edge of the side wall and the rear edge of the bottom wall. The air conditioner's partition has attachment hook receiving slots formed therein, which are configured to receive the attachment hooks therein in a manner attaching the main housing to the partition with the rear edges of the bottom wall and the side wall in confronting relation with the partition.

Control box for a room air conditioner

An air conditioning unit is provided, which includes an outdoor section which has a condenser coil mounted therein and an outer protective housing at least partially enclosing the outdoor section. The housing has a substantially rectangular opening therein in overlying relation with the condenser coil. The opening is defined by four coplanar wall sections of given thickness. Each wall section has an edge thereof, which cooperates with the edges of the other wall sections to define the perimeter of the opening. A one-piece molded plastic grille is configured to substantially cover the opening. The grille includes an outer framework sized to be substantially contiguous with the perimeter of the rectangular opening. The outer framework is defined by upper, lower and left and right frame members, which are interconnected at the ends thereof to define the outer framework. A plurality of inclined horizontal louvers extend between the left and right frame members. Grille positioning and retaining structure are integrally formed with each of the frame members. Each of the positioning and retaining structures includes a first portion extending outwardly from its respective frame member in overlying relationship with one of the coplanar wall sections, and a second portion extending outwardly from its respective frame member in underlying relation with its associated coplanar wall section. The first and second portions are spaced from one another by a distance equal to the given thickness of the coplanar walls to define a space therebetween configured to receive the edge of and a portion of the coplanar wall therein. The plastic grille is sufficiently flexible to allow it to be deformed to a condition to allow each of the grille positioning and retaining structures to engage their respective coplanar wall sections and to thereafter to return to an undeformed condition when assembled to the housing.
