DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
This invention relates generally to air conditioning systems and, more particularly, it relates to an arrangement for mounting the evaporator coil in a room air conditioner.
BACKGROUND ART
The indoor section of a room air conditioner or the indoor section of a split system air conditioner typically includes a housing which has mounted therein the evaporator coil, an indoor fan, electrical controls, and structure for directing room air to the evaporator coil and redirecting conditioned back into the space to be cooled. Designers of room air conditioners are constantly striving to increase the capacity of and efficiency of their units and at the same time reduce the size and costs of their products. The fewer the number of components, and the fewer the number of fasteners necessary to assemble those components results in a more cost effective air conditioner as a result of the decease in material and labor costs.
It is accordingly considered desirable to provide on indoor section of a room air conditioner wherein the mounting of the evaporator coil is carried with no fasteners and is supported by molded plastic components forming a part of the air conditioner housing and other support as supplied by components for directing the flow of air therethrough.
DISCLOSURE OF THE INVENTION
According to the present invention, apparatus is provided for mounting an evaporator coil within an indoor section of an air conditioner. The air conditioner includes an indoor section having a housing in which an evaporator coil having a top and vertically extending tube sheets is mounted. The evaporator is supported by a horizontally extending support surface formed at the front end of the housing for supporting the lower ends of the tube sheets. First and second vertically extending evaporator support structures are disposed at each end of the horizontally extending support surface. Each of the first and second support structures are adapted to receive one of the tube sheets therein as the evaporator is displaced downwardly into engagement therewith and towards engagement with the horizontally extending support surface. A scroll structure for directing air flow through the indoor section is provided with vertically extending evaporator support channels which are in axial alignment with the vertically extending evaporator support structure in the housing. The scroll structures are adapted to be engaged with the upper ends of the tube sheets following engagement of the evaporator and tube sheets with the vertically extending evaporator support structure.
