DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention is directed to room air conditioners, and more particularly the construction of the outdoor or condensing section of an air conditioner.
BACKGROUND ART
Room air conditioners generally include an air inlet fan or blower which is powered by a motor to draw air in through an evaporator coil to be cooled and to direct the cooled air back into the room. Such air conditioners also include a condenser coil for dissipating the heat picked up by the evaporator coil and a second fan or blower is provided to cause an air flow over the condenser coil to increase the heat dissipation of that coil.
A typical arrangement of the outside section of an air conditioner which houses the condenser coil and fan is for the fan motor and fan assembly to be mounted in a bracket of some sort attached to a base pan of the outdoor section. It is desirable to provide a shroud surrounding the outdoor fan. It is also desirable for the tolerances between outdoor fan and the shroud to be as close as possible.
Due to the complexity and the number of parts associated with mounting the fan motor and fan and supporting such a shroud, assembly of such a device often times includes complicated and time intensive assembly steps and requires intricate manipulation of parts and tools. This results in an increased cost of the room air conditioner due to increased material and labor costs.
DISCLOSURE OF THE INVENTION
According to the present invention, a condensing module for an air conditioner is provided with a substantially rectangular housing having a front wall and back wall. The housing is formed from upper and lower housing sections molded from plastic. The lower section has a base which has molded therewith structure for mounting of an outdoor fan assembly positioned near the front wall, and structure for mounting of a compressor. Further molded with the lower section is an upstanding wall located between the fan assembly and the back wall. The wall defines a condenser fan shroud and, at its upper end, defines spaced apart upwardly facing structural support surfaces on opposite sides of the shroud. The upper housing section has a top wall having molded therewith a downwardly extending wall section which cooperates with the lower section to define the condenser fan shroud. The upper wall also defines at its lower end spaced apart downwardly facing structural surfaces located such that the upwardly facing structural support surfaces of said upstanding wall and said downwardly facing structural and planar surfaces of said downwardly extending wall are in confronting engagement with one another when the upper and lower housing sections are assembled to form the rectangular housing.
