Extracting device for removing air, combination appliance and suction arm

An extraction device for removing air from an area above a cooktop, the extraction device comprising:

• a suction arm having an elongated suction base and a suction head pivotally connected to a first end of the suction base about a first lateral pivot axis, the suction base defining therein an air duct in fluid communication with an inlet opening in the suction head, the suction base extending forward along a centerline of said cooktop from a second end of the suction base adjacent to a rear of the cooktop and being further pivotally connected at said second end to a stationary bottom unit disposed beneath the cooktop about a second lateral pivot axis parallel to the first lateral pivot axis;
• and
• a fan disposed in said bottom unit and configured to suck said air in through said inlet opening;
• wherein the duct in said suction base is also in fluid communication with an outlet opening of said bottom unit, wherein air sucked in through said inlet opening will be conducted through said duct and out to an ambient environment through said outlet opening;
• wherein said suction arm is adjustable between a resting position and an operative position wherein said suction opening of the suction head is located above and adjacent to one or more of cooking zones of the cooktop;
• and
• wherein a height of said suction opening in the suction head relative to said cooktop is adjustable by adjusting a first pivot angle between the suction base and the cooktop relative to said second lateral pivot axis,
• wherein the suction base of the suction arm is pivotally connected to the cooking hob such that the suction base is pivotable about a vertical pivot axis,
• wherein said suction base is telescopically extensible, wherein through concurrent adjustment of said first pivot angle, a length of said suction base, and a second pivot angle between the suction head and the suction base relative to said first lateral pivot axis, said suction opening can be freely adjusted within a vertical plane substantially intersecting said centerline in the area above said cooktop, and
• wherein in said resting position, said elongated suction base and said suction head are received through one or more cut-outs within the cooktop so that upper surfaces of the suction base and suction head are substantially flush with a surface of said cooktop, said suction base further comprising at least one sensor configured to face the area above said cooktop when the suction base is deployed, to detect one or more of humidity, temperature, and optical images, and to communicate data to a controller that is configured to adjust a speed of said fan in dependence of said data.
