A kitchen hood has a first housing and a second housing that slides into and out of the first housing to adjust a length of the kitchen hood. The first housing has a fan to suction air, an outlet, and an air quality sensor assembly to continuously detect air quality in a kitchen. The second housing has an inlet and suction grill through which air is suctioned, a steam cleaning assembly to automatically steam clean an interior of the kitchen hood, and a height sensing assembly to sense a height of cookware seated on a cooktop surface below the second housing. The kitchen hood may be lengthened or shortened based on the sensed height of the cookware, and a speed of the fan and the height of the kitchen hood may be automatically adjusted based on detections by the air quality sensor assembly.

A downdraft ventilation system includes a vertically movable chimney with two ventilation inlets and a baffle arranged within the chimney between the inlets. The combination of upper and lower ventilation inlets and internal baffle can function to increase the amount of cooking emission captured and exhausted by the downdraft system.

A cooking device includes a main body having a cooking space for cooking food; a base disposed at a lower side of the main body, and comprising a ventilation apparatus for suctioning and discharging contaminated air, the ventilation apparatus being connected to the lower side of the main body and having an introduction port; a swirler rotated so that the contaminated air is suctioned through the introduction port of the base, and having a plurality of wings; an installation part provided at the base; and a driving motor installed at the installation part and configured to generate power for rotating the swirler.

A range hood, including a housing with an opening at one side and a fume inlet panel component which is provided on the housing, the fume inlet panel component is provided at the opening of the housing, a fan is provided in an inner cavity of the housing, the fume inlet panel component is configured in such a way that at least a region of the opening of the housing corresponding to the fan can be opened, and the fan can be removed from the region. When the fan and an inner surface of a volute need to be cleaned, a user can conveniently remove the fan from one side of the fume inlet panel component and clean the removed fan and access an interior of the volute to clean an inside surface of the volute, ensuring extraction capability and increasing a service life of the range hood.

A ventilation system is provided. The ventilation system includes a ventilation cover configured to be coupled to a kitchen range hood, the ventilation cover including a retractable tube, and a securing mechanism for coupling the retractable tube to the kitchen range hood, wherein the retractable tube includes a lower opening configured to be mounted to an upper surface of a piece of cookware when in an extended position, and wherein the retractable tube includes an upper opening.

An exhaust canopy comprising: a stationary portion adapted for mounting on a stationary object, above cooking equipment; an exhaust portion for removing or filtering cooking effluent or fluids, the exhaust portion being adjustably connected, directly or indirectly, with the stationary portion or the stationary object; and an adjustment mechanism for moving the exhaust portion with respect to the stationary portion or the stationary object; wherein the exhaust canopy is adjustable between a first configuration in which the exhaust portion is raised, retracted or withdrawn and a second configuration in which the exhaust portion is lowered, protracted, or extended.

A range hood is provided. The range hood includes a volute casing, a volute casing air inlet and a volute casing exhaust outlet in communication with a hood exhaust outlet are provided in the volute casing. The volute casing includes a fixed housing part and a movable housing part, the movable housing part is movable relative to the fixed housing part; the fixed housing part is fitted with the movable housing part and air is discharged from the volute casing exhaust outlet when the movable housing part is in a closed position; the movable housing part is staggered relative to the fixed housing part to allow the air to be discharged into a room when the movable housing part is in an open position. When the range hood exhausts air to the room, a flow distance of the air is short, improving operational efficiency.
