DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention is directed to air conditioners, and is particularly directed to the arrangement and configuration of the components of the indoor section of an air conditioner of the type used for cooling a room.
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, indoor fan motor, electrical controls and structure for directing room air to the evaporator coil and redirecting conditioned air back into the space to be cooled. Designers and builders of room air conditioners are constantly striving to increase the capacity and efficiency and reduce the size and cost of their products. The fewer the number of components, and the fewer the number of fasteners necessary to assemble those components, result in a more cost effective air conditioner as a result of the decrease in material and labor costs.
It is accordingly considered desirable to provide an indoor section for use with an air conditioner wherein substantially all structural components are made from a number of integrated precision resin molded components. Such a design will minimize the number of components, facilitate ease of assembly and minimize the number of separate fastener parts, such as screws, clips or other similar fasteners.
DISCLOSURE OF THE INVENTION
According to the present invention, an evaporator module for an air conditioner includes a substantially rectangular structural evaporator housing having a rear wall and a substantially open front. An air directing scroll is mounted within the housing adjacent the rear wall. Scroll aligning structures, provided on the rear wall of the housing, cooperate with structure on the scroll to support the scroll in its operative position. An evaporator fan and motor subassembly are mounted directly to a support extending from the rear wall. The rear wall of the housing and the scroll are provided with axially aligned openings which receive at least a portion of the evaporator fan motor therein. An evaporator coil and evaporator coil support subassembly is positioned in substantially confronting relationship with the evaporator fan and the scroll to thereby support the scroll and to further define the air inlet path across the evaporator and into the evaporator fan.
