Sorry, but it certainly doesn't complement your beautiful King Aire ;) . Some looking at your setup, and then your rig might assume how you afforded to buy the rig in the first place. My wife wouldn't of allowed that and would have expressed her feeling in not so nice terms.
But looking closely at your contraption, the connection to the exhaust, I could be wrong but what is allowing cold air from the bottom into the venting. The real Venturi actually sits just outside of the exhaust leaving a gap before the Venturi tube. I'm not a hi-vac guy, but could that dryer vent opening be too big to allow for any Venturi effect? I think your really just trying to direct the exhaust, and quite possible could be kidding yourself thinking you've a Venturi solution.
