Abstract
An exhaust hood having an inverted V-shaped interior, the walls comprising the inverted V including grease filters and the apex of the inverted V lying adjacent to an exhaust duct to be placed in communication with an exhaust fan. The interior of the hood thus being shaped like an inverted funnel, rising gases and entrained contaminants are directed to the grease filters and thence to the exhaust duct.
Claims15
An exhaust hood comprising:
- a housing having a pair of opposing end panels and an open underside;
- interior surfaces forming an inverted V in transverse section, the interior surfaces and the end panels defining a cavity extending upwardly within the housing from the open underside;
- at least one filter providing at least a portion of the interior surfaces;
- and
- an exhaust outlet formed in the housing above the apex of the inverted V formed by the interior walls, the exhaust outlet being in fluid communication with the cavity by way of the filter;
- whereby the cavity and the exhaust outlet provide a flow path in the manner of an inverted funnel for rising gases and entrained contaminants.

An exhaust hood comprising:
- a housing having an upper panel, a pair of opposing end panels depending from the upper panel, and an open underside;
- a pair of grease filters supported within an upper portion of the housing, the grease filters extending between the end panels and sloping downwardly and outwardly in opposite directions from a central portion of the housing;
- a pair of interior walls supported within the housing in spaced relation to each other;
- each of the interior walls extending between the end panels below a respective one of the grease filters and sloping downwardly and outwardly in planes parallel to the planes of said respective one of the grease filters;
- the grease filters and the interior walls defining a cavity having an inverted V-shape in transverse section and extending upwardly within the housing from the open underside between the end walls;
- an exhaust plenum formed in the housing above the apex of the inverted V defined by the grease filters and the interior walls, the exhaust plenum being in fluid communication with the cavity by way of the grease filters;
- and
- an exhaust outlet formed in the upper panel, the exhaust outlet being in fluid communication with the exhaust plenum;
- whereby the cavity, the exhaust plenum, and the exhaust outlet provide a flow path in the manner of an inverted funnel for rising gases and entrained contaminants.
