ABSTRACT:
A combination bath fan, register box, air conditioning and heating boot requires one opening on the wall or the ceiling of the bathroom, thus reducing the installation and maintenance costs associated with the ventilation of the bathroom. The combination includes a trim kit or assembly which is adapted to be fitted into a rough-in kit or assembly. The rough-in kit or assembly, typically mounted onto a building stud during the early phases of the building construction, has an air outlet which is connected to the outside air and an inlet for receiving conditioned air to be distributed within a confined space. The trim assembly or kit is installed in the rough-in assembly. Louvers are provided around the perimeter of the face plate of the trim assembly to dispense conditioned air from the air inlet to the confined space with the appropriate air gradient. Air flow through the louvers is controlled using one or more slidable dampers mounted above the louvers. Further, one or more baffles are positioned centrally on the face plate to guide the removal of stale air from the confined space. A fan housing having a motorized fan assembly is centrally positioned above the face plate to draw stale air and other odoriferous fumes from the confined space through the baffles and to eject the noxious fumes to the outside atmosphere. The present invention thus provides an economical, aesthetically pleasing, yet high performance air exchange system which can be installed in fewer steps and which provides a less intrusive appearance on the ceiling or wall of the confined space.
