Abstract:
A structural framework for an air distribution unit of the type including a housing defining an air inlet, an air outlet, an air flow path therethrough extending from said inlet to said outlet, an evaporator coil supported in said housing in said air flow path, and a fan for effecting air flow along said air flow path and through said evaporator coil, wherein the improvement comprises:a main support frame including a horizontally extending planar bottom section having a predetermined depth and width, a vertically extending back section, having a predetermined height extending upwardly from the back of said bottom section, and a top section extending forwardly from the top of said back section, a distance less than said predetermined depth of said bottom section;each of said back section and said top section having the same width as said planar bottom section, each of said bottom section and said back section having right and left-hand edges;a vertically extending right side wall having a lower edge substantially equal in length to said predetermined depth of said bottom section, and a rear edge having a height less than said predetermined height of said back section, said lower edge and said rear edge being structurally interconnected to the right-hand edges of said bottom section and said back section, respectively;a vertically extending left side wall having a lower edge substantially equal in length to said predetermined depth of said bottom section, and a rear edge having a height less than said predetermined height of said back section, said lower edge and said rear edge being structurally interconnected to the left-hand edges of said bottom section and said back section, respectively;each of said right and left side walls having a substantially rectangular lower section having a depth substantially equal to said predetermined depth of said bottom section and having an upper end terminating at a height intermediate the height of said rear edge, each of said right and left side walls further having an upper triangular section extending from a base overlying said upper end of said rectangular section, and a hypotenuse which extends from a point intermediate said upper end, rearwardly to the upper end of said rear edge;each of said right and left side walls also having a horizontally extending channel extending the depth of said lower section of said walls and located between said upper end of said rectangular lower section and said base of said triangular section; anda substantially planar fan mounting panel having right and left edges thereof configured to be received in said horizontally extending channels of said right and left side wall, respectively, said fan mounting panel having a depth substantially equal to said predetermined depth of said bottom of said main support panel.
