A commercial cooking equipment exhaust hood system includes a hood structure including an inlet opening to an exhaust flow path through the hood. A filter unit is positioned along the exhaust flow path. An electrostatic precipitator unit is downstream of the filter unit. The electrostatic precipitator includes an ionizing section upstream of a collecting section. The ionizing section includes a plurality of ionizing flow paths having side profile patterns that vary in width between at least one wide section and at least one narrow section. The collecting section includes a plurality of collecting flow paths with side profile patterns of substantially uniform width and a repeating undulating side profile pattern. A UV light source may also be provided within the hood, with a controller operatively connected to control the UV light source via a dimmer to enable selective production various UV levels.

An over-the-range appliance mountable over a cooktop appliance is provided. The over-the-range appliance includes a cabinet comprising a bottom panel defining a central aperture, a lighting box mounted within the central aperture. The lighting box defines a lighting recess and one or more light sources are mounted to the lighting box and are positioned within the lighting recess. A diffuser plate is positioned over the one or more light sources and encloses the lighting recess.

The present disclosure relates to an exhaust device. The exhaust gas according to the present disclosure includes a base plate and a swirler. The base plate includes a swirler installation part, an auxiliary intake part, a suction port opened in the swirler installation part, and an auxiliary suction port opened in the auxiliary intake part. In this case, air flows through the base plate via the suction port and the auxiliary suction port.

The LED luminaire is constructed with an LED/driver printed circuit board mounted directly on a floor of the heat sink assembly. By mounting the LED/driver printed circuit board directly in and on the heat sink assembly, the heat imposed on the LED/driver printed circuit board during use in a canopy hood over a cooking surface is transferred directly to the heat sink assembly for dissipation.

A hood extension assembly for use with an above the stove microwave having a built-in ventilation system. The hood extension assembly is fixedly or movably mountable to an underside of an above the stove microwave or to the surrounding cabinetry. A skirt body of a hood panel sloped downward from back to front extends from the front of the microwave to extend over and cover the front burners of the stove or cooktop. A pair of side panels attach to the hood panel and extend rearward to protect the surrounding cabinetry. The pair of side panels may attach directly to the underside of the microwave or to a bracket component attachable to the underside of the microwave.

A combination appliance (1) comprising a cooking hob (2), which comprises at least one support surface (4) and at least one therein formed recess (11), and at least one extraction device (3), which is arranged below the support surface (4) of the cooking hob (2) and comprises at least one fan (15) for sucking air from the space above the cooking hob (2) through the recess (11) of the support surface (4), and at least one lid (20) for the recess, wherein at least one control module (28), comprising at least one extraction control (18) that controls at least one operation parameter of the extraction device (3), at least one hob control (6) that controls at least one operation parameter of the cooking hob (2), and at least one interface unit (29) that is at least connected to the extraction control (18) and to the hob control (6), and wherein the interface unit (29) is capable of sending signals to the extraction control (18), wherein the extraction control (18) is controlling the extraction device (3) in response to the signals received from the interface unit (29).

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.
