Abstract
An exhaust hood includes a housing, which is open towards a bottom face to capture cooking by-products from a cooking appliance positioned below the exhaust hood. The housing has a first wall and a second wall opposite to the first wall. The second wall is at least partly inclined inwardly from the bottom face towards a top face of the housing and has an exhaust vent to extract cooking by-products captured by the housing. The exhaust hood has a fresh air fan and the first wall forms a first duct which has openings located in a row along a lower edge of the first wall adjacent to the bottom face and oriented inside the housing. A side wall extension extends from one side wall and forms a lateral skirt that defines a pass-through window having vertically and horizontally extending faces. The side wall extension forms a side wall duct with openings along the vertically and horizontally extending faces that eject vertical and horizontal air streams orthogonal to one another that coalesce to form a vortex which limit cooking by-products from passing through the pass-through window.
