Benefits of technology

"The present invention provides an improved attachment assembly for an air-conditioning system that connects the air-conditioning coil housing and the drain pan. The attachment assembly includes a receptacle wall for the drain pan and a coil housing wall that slidingly engages the receptacle wall. A gripping arm is also included that extends from the coil housing wall and is engageable with the receptacle wall. The gripping arm has an enlarged lip portion that prevents separation of the coil housing wall from the receptacle wall. The attachment assembly is designed to be easily serviceable after installation and provides a reliable connection between the air-conditioning coil housing and the drain pan."

Problems solved by technology

While these components can be fairly conveniently bolted together at the manufacturing plant when easier access to these interior portions of the system is available, the same easy access is normally not available once the system is installed thereby making servicing and / or replacement of these components relatively time-consuming and difficult.

Embodiment Construction

[0031] Referring now to the drawings and, more particularly to FIG. 1 wherein an overview is provided of a presently preferred internally disposed attachment assembly 10 between air-condition coil housing 12 and drain pan 14. As indicated in FIG. 2, in general, at least two internally disposed attachment assemblies 10 may be utilized on either end of coil housing 12 at locations as indicated at 20 and 22. However, because the details of each attachment assembly 10 are substantially similar or identical except for a change in position, only one attachment assembly is discussed herein and it will be understood that the discussion applies to all such attachment assemblies.

[0032] An understanding of how internally disposed assembly 10 operates is perhaps best seen in FIG. 8 wherein an internal cross-section is provided wherein the relevant components are enlarged. Wall 16 of the coil housing preferably includes downwardly extending wall portion 24 which extends into or to the floor of ...

Abstract

An assembly and method is provided for an air-conditioning system coil housing and a plastic drain pan wherein the coil housing has one or more sheet metal walls. A first flap is cut and formed in at least one sheet metal wall which is resiliently bendable away from the metal wall. A second flap is cut and formed in the first flap. The drain pan comprises an outwardly extending lip portion such that when the coil housing is mounted to the drain pan then the sheet metal wall slidingly engages a drain pan wall whereby the first flap portion bends outwardly to catch the lip portion such that the second flap engages an underside of the outwardly extending lip portion.

Description

[0001] This application claims benefit of U.S. Provisional Application No. 60 / 653,773 filed Feb. 17, 2005, which is incorporated herein in its entirety.TECHNICAL FIELD [0002] The present invention relates generally to air conditioning assemblies and, more particularly, to an improved assembly and method for securing an air conditioning coil to a drain pan. BACKGROUND [0003] After installation of an air-conditioning system, and during the lifetime of the system, it may become necessary to repair or replace the air-conditioning coil and / or drain pan. The connection between these components requires access to the interior portions of the drain pan and air conditioning coil housing. While these components can be fairly conveniently bolted together at the manufacturing plant when easier access to these interior portions of the system is available, the same easy access is normally not available once the system is installed thereby making servicing and / or replacement of these components re...
