An extraction hood of the up-and-down type for extracting fumes and/or vapours generated on a hob includes a fixed first hood portion (2) and a second extraction hood portion (4) set at a distance from the first extraction hood portion (2) and close to the hob, the second hood portion containing an extraction device (6) capable of drawing in air containing fumes and/or vapours from the hob and directing it towards an opening (11) in the second hood portion (4) to be discharged therefrom and passed towards the first hood portion (2). A conveyor (10) for the discharged air is provided at the opening (11) of the second hood portion (4). The conveyor includes a body (30) having a tubular annular shell (31) containing a honeycomb structure (32) with a number of tubular cells (42) through which the air leaving the second hood portion (4) is discharged.

An extractor hood capable of extracting fumes and/or vapours being generated on a cooking surface, the hood including a first portion (2) integral with a wall (3) of the room where the cooking surface is located, a second portion (4), spaced apart from the first and close to the cooking surface, and a support connection (50) capable of securing the first portion (2) to the second portion (4), the second portion containing a fan (5) capable of extracting fumes and/or vapours from the cooking surface when the hood (1) is in use. The first portion (2) includes an autonomous extraction device capable of extracting fumes and/or vapours exiting the second portion (4) and extracted from the cooking surface by the fan (5) present in the second portion (4), the hood having no connecting tube between the second portion (2) and the first portion (4).

A venting appliance for use with a cooking appliance including a cooktop with at least one cooking element disposed thereon, where the venting appliance may include: a housing configured to be positioned above the cooktop; a repositionable vent arm coupled to and extending below the housing; and a controller coupled to the repositionable vent arm and configured to determine that a first cooking element among at least one cooking elements is active, and in response thereto, automatically reposition the vent arm to be closer to the first cooking element.

A downdraft ventilator includes: at least one housing device for installation into least one cabinet body below at least one countertop; at least one vapor-collecting hood device having at least one intake opening for cooking vapors, and, when installed, the at least one vapor-collecting hood device at least partially extends through at least one opening in a countertop; at least one mounting frame fittable into an opening of the countertop, the at least one mounting frame having at least one opening for the vapor-collecting hood device; and at least one supporting device having at least one supporting element, the at least one supporting device being mounted on the at least one housing device, and the at least one supporting element causing the at least one mounting frame and/or a cooktop device disposed adjacent thereto to be supported at least in some portions.

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 range hood includes a body having a space formed therein, and multiple grooves are formed in the inside of the space. The body includes an opening in the underside thereof The opening communicates with the space. A ease includes multiple rails which are slidably located in the grooves. A frame is located in the space and includes a blower. A driving unit is located in the space and connected to the case so as to lift and lower the case by moving the rails along the grooves.

Proposed is a variable hood apparatus. The variable hood apparatus includes a support holder fixed to a wall, a rotation holder configured to be rotatable around a vertical axis of rotation while being supported by the support holder, an arm portion supported by the rotation holder and configured to be capable of performing a three-dimensional movement, a foldable hood mounted on an end portion of the arm portion, the foldable hood being configured to be unfolded while being used and to be folded while being not used, an exhaust pipe which is connected to the foldable hood and which extends to an outside, and an exhaust mechanism configured to generate an airflow which is formed inside the exhaust pipe and which is in a direction toward the outside, thereby inducing a negative pressure in the foldable hood.

A variable hood apparatus includes a bent column fixed to a wall of the kitchen, a support body detachably mounted on the bent column and configured to be capable of adjusting a height level thereof, a first horizontal bar supported by the support body and configure to be rotatable, a slider mounted on the first horizontal bar and configured to be slidable, a second horizontal bar supported by the slider and configured to be rotatable, a foldable hood mounted on an extension of the second horizontal bar, the foldable hood being configured to be unfolded while being used, an exhaust pipe which is connected to the foldable hood and which extends to an outside, and an exhaust mechanism generating an airflow which is formed inside the exhaust pipe and which is directed toward the outside, thereby inducing a negative pressure.

A portable air flow apparatus may include a base configured to be seated on a surface, a head comprising a suction inlet through which air is suctioned into the head and a discharge outlet through which the air suctioned in through the suction inlet is discharged, the suction inlet and the discharge outlet being horizontally spaced apart from each other at a right angle with respect to a vertical direction, and a column that connects the head and the base in such a manner that the head is vertically spaced from the base.
