Return air apparatus with down draft diverter

A return air apparatus for use with an air comfort appliance unit comprising:

• a ceiling template adapted to be mounted to the air comfort appliance unit at a ceiling of a recreational vehicle at a position spaced from the air comfort appliance unit to form a plenum area between the ceiling template and the air comfort appliance unit, the ceiling template having a discharge opening and a return opening,
• an air barrier extending from the ceiling template to divide a plenum area between the ceiling template and the air comfort appliance unit into a discharge section and a return section,
• a return air cover with a direct discharge opening positioned below the discharge opening of the ceiling template, and a return opening positioned below the return opening of the ceiling template,
• a down draft diverter positioned in the return air cover over the direct discharge opening of the return air cover,
• a return air grille with a first section positioned to communicate with the discharge opening of the ceiling template and a predetermined area of the interior of the recreational vehicle, and a second section positioned to communicate with the return opening of the ceiling template and the interior of the recreational vehicle, and
• a filter positioned between the return opening of ceiling template and the return opening of the return air cover, wherein the filter is positioned remote from the return air grille to maximize filter area and minimize air flow resistance,
• wherein, in use, air may be drawn through the second section in the return air grille, through the return opening in the return air cover, through the filter, and then through the return opening in the ceiling template,
• wherein the down draft diverted diverter is adapted to be moved with respect to the ceiling template to create an opening between the down draft diverter and the ceiling template such that air can be discharged directly through the direct discharge opening of the return air cover.

A return air apparatus for use with an air comfort appliance unit comprising:

• a ceiling template adapted to be mounted to the air comfort appliance unit at a ceiling of a recreational vehicle at a position spaced from the air comfort appliance unit to form a plenum-area between the ceiling template and the air comfort appliance unit, the ceiling template having a discharge opening and a return opening,
• an air barrier extending from the ceiling template to divide a plenum area between the ceiling template and an air comfort appliance unit into a discharge section and a return section,
• a return air cover with a direct discharge opening positioned below the discharge opening of the ceiling template, and a return opening positioned below the return opening of the ceiling template,
• a slide positioned in the return air cover over the direct discharge opening of the return air cover, and
• a return air grille with a first section positioned to communicate with the discharge opening of the ceiling template and a predetermined area of the interior of the recreational vehicle, and a second section positioned to communicate with the return opening of the ceiling template and the interior of the recreational vehicle,
• wherein the slide is adapted to translate with respect to the return air cover to create an opening between the slide and the ceiling template such that air can be discharged directly through the direct discharge opening of the return air cover and wherein the slide is adapted to interact with the return air cover to facilitate maintenance of the opening between the slide and the ceiling template at predetermined degrees of openness.
