Slide-type range hood

An exhaust device, comprising:

• a fan plenum with a fan;
• a jet plenum having one or more jet openings on a distal end thereof configured to create a planar jet;
• the jet plenum being movably attached at a proximal end thereof to the fan plenum to permit sliding movement of the jet plenum relative to the fan plenum;
• the fan plenum and the jet plenum each having a respective flow-transfer opening that overlaps the opening of the other, the respective openings being shaped and arranged to remain overlapped in all positions to which the jet plenum is moved relative to the fan plenum such that an interior of the fan plenum and the jet plenum remain in fluid communication to allow air to flow from the fan to the jet plenum to the one or more openings and form a jet through the one or more jet openings;
• and
• the fan having an intake at a top of the fan plenum which is covered by a louvered grill of the jet plenum when the jet plenum is in a fully retracted position thereby permitting air to flow into the intake.
