In one aspect of a vapor detecting device for a cooking appliance and a unit containing a cooking appliance and a vapor detecting device, the exhaust air that flows in through a first opening and/or through a second opening into the vapor collecting device flows through the following stations arranged within the vapor collecting device, one after the other, namely: a coolable body, as a station of the condensation device, so as to clean the exhaust air of aerosols and water droplets and to condense out at least part of the steam and preferably partially cool it; a grease separator filter as the first station of the treatment device; a sponge filter as the second station of the treatment device; a plasma as the third station of the treatment device, for sterilization, ionization and/or dissociation; and an activated charcoal filter as the fourth station of the treatment device.

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.

The present invention description to a hood for extracting cooking fumes comprising: a base having an intake opening that can be facing a hob; a conduit extending along a longitudinal direction (X-X), connected to said base and having a discharge opening placed in fluid communication with the intake opening of the base; a first and a second suction unit arranged in the conduit and configured to respectively generate a first air flow and a second air flow that cross the conduit from the intake opening to the discharge opening, the first and second suction unit extending parallel for the same length along a depth direction (Z-Z) perpendicular to the longitudinal direction (X-X). A feature of the hood is that the first and the second suction unit are spaced along the longitudinal direction (X-X), and partially overlapping along a transverse direction (Y-Y) perpendicular to the longitudinal direction (X-X) and to the depth direction (Z-Z).

A range hood for preventing air pollution is disclosed and includes a main body, a gas guider, a filtration and purification component and at least one gas detection module. The main body is configured to form a diversion path. The gas guider is disposed in the diversion path for guiding an air convection. The filtration and purification component is disposed in the diversion path for filtering and purifying an air pollution source contained in the air convection guided by the gas guider. The at least one gas detection module is disposed in the diversion path for detecting the air pollution source and transmitting a gas detection datum.

The present invention is related to a combination appliance (10) comprising a cooking hob (12) and an extraction device (14). The cooking hob (12) comprises at least one cover plate or worktop (22) having an opening (24) or a recess formed therein. The extraction device (14) is arranged below the cover plate or worktop (22) and comprises at least one fan (36) for sucking air from the area above the cooking hob (12) through the opening (24) or recess of the cover plate or worktop (22). The extraction device (14) further includes at least one filter carrier (50) and at least one filter (52; 52a, 52b), which is removable through the opening (24) or recess. According to the invention, the extraction device (14) comprises at least one liquid collector (28a, 62, 74, 76, 76′) and a lid or grid (26), which is inserted in the opening (24) or recess. The at least one liquid collector (62) is preferably removable through the opening (24) or recess of the cover plate or worktop (22) and/or may comprise at least one overflow opening (68).

A bracket for mounting an over-the-range cooking appliance, where the bracket includes: a bracket body adapted to be secured to a wall and support a cooking appliance, the bracket body further including a vent opening to engage an exhaust of the cooking appliance; an exhaust adaptor, where the exhaust adaptor further includes: a first side and a second side, and the first side is located opposing the second side with a through opening; where the second side of the exhaust adaptor is adapted to engage an external vent; and when the first side of the exhaust adaptor is engaged with the bracket body at the vent opening, there is fluid communication between the vent opening and the exhaust adaptor.

A cooking system includes: at least one control device; at least one extractor device; at least one cookware item; and at least one stovetop. The at least one extractor device includes at least one movable vapor screen device having at least one suction opening in operative connection with at least one fan device. The at least one stovetop device includes at least one placement device for placing cookware and at least one heating device for heating cookware. The at least one movable vapor screen device is movable to at least two operating positions with at least one different extension height in each case.
