DRIVER VENTILATION FOR DELIVERY TRUCK

摘要

The present invention involves a vehicle (60) with an improved ventilation system including a chassis (61) and vehicle body (63). The vehicle body is mounted on the truck chassis, and has a floor, a ceiling (22), a front section (81), and a back section (83). The front section defines a vent opening (68) and has a duct (20) mounted on the ceiling. The duct extends from the vent opening, and has at least one air portal (30) structured and arranged to direct air into the vehicle body. The duct includes a main passage (36) and projections (42, 44), which are partially defined by sloping walls (46, 48) so as to provide a lessened constriction of air flow from an intake passage (38). The intake passage extends upward from the vent opening to impede moisture from entering the main passage, and the projections and slope of the intake passage serve to drain away any moisture that does manage to enter the main passage.
