A filtered ventilating system for a cooking unit incorporates a hood emplaceable above a cooking unit. An exhaust stack extends from the hood for removing cooking fumes captured by the hood. A barrier wall divides the interior of the hood into inlet and outlet zones open to the cooking unit and exhaust stack, respectively, and is provided with a fume opening to receive a filter for grease and the like. Wash down pipes respectively extend along the exhaust zone of the hood adjacent the filter and along an exhaust stack. A motor rotates the wash down pipes and a suitable supply provides wash liquid to the pipes, which are thus energizable to simultaneously rotate and spray the wash liquid onto adjacent hood, filter and exhaust stack surfaces for cleaning same. Pivot and latch apparatus supports the filter for reversal on the barrier wall, to permit both sides of the filter to be cleaned by liquid from the wash down pipes.

In a filtered ventilating system for a cooking unit, including: a hood emplaceable above a cooking unit and opening downward theretoward for capturing fumes released during cooking; an exhaust stack for removing cooking fumes entrapped by said hood, a barrier wall extending widthwise of said hood and dividing the interior of said hood into inlet and outlet zones respectively open to said cooking unit and said exhaust stack, said wall having a fume opening therethrough; a filter panel disposable across said fume opening to filter out grease and the like from said cooking fumes prior to entry into said exhaust stack; latch means for holding said filter panel in place in said fume opening; the improvement comprising: a pair of links, first pivots at one end of said links pivotally mounting said links on said barrier wall at opposite sides of said fume opening, the other ends of said links being pivotable from a retracted position extending along said barrier wall; second pivots at said other end of said links pivotally mounting the central portions of sides of said filter panel on said other ends of said links for rotation of said filter panel through at least 180°with respect to said links, the maximum spacing from said first to said second pivots on each link exceeding one-half the height of the filter panel, said links being pivotable on said first pivots to an extended position angling at about a right angle from said barrier wall into said inlet zone for permitting said 180°rotation of said filter panel without interference between said filter panel and barrier wall; said barrier wall including a bottom lip along the front bottom edge of the fume opening and extending upward to block the bottommost portion of the filter panel from moving forward into said intake zone; said links each incorporating lost motion means acting along the length thereof (1) for increasing the separation between the first and second pivots on each link to achieve said maximum spacing, and (2) for decreasing the separation between the first and second pivots on each link to permit the lower edge of the filter panel to clear said bottom lip as said filter panel enters or leaves said fume opening.
