A method of controlling an electrical household system, comprises: starting a pyrolysis process in an oven, wherein the oven is connected or configured to be connected in signal communication to a household range hood; starting a suction device of the household range hood as a function of a communication signal from the oven, wherein said signal is correlated to the pyrolysis process in the oven.

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).
