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 ventilation hood is mounted to an underside of a cabinet by left and right support brackets each including a main body from which depend at least one support tab or hanger, as well as a locator tab. The main body is aligned on the cabinet, while the locator tab appropriately spaces the support bracket from an upstanding rear wall. Thereafter, the ventilation hood is positioned so the support tabs are received in slots formed in a top panel of the hood and, upon sliding the hood rearward, the hood rides upon ramped or tapered surfaces of the support tabs to position the hood against the cabinet while hanging the hood from the support tabs. Thereafter, the support tabs are bent to retain the ventilation hood in an operational position. Employing the distinct aligning, positioning and hanging structure enables a single person to readily mount the ventilation hood.

An exhaust system for use in a kitchen, the exhaust system including a hood body having a top rear panel, a left side panel, a right side panel, and a bottom rear panel. The exhaust system further includes a filter, a motor assembly, and a fan disposed at an angle relative to the top rear panel of the hood body. In one embodiment, the fan is disposed between the filter and the motor assembly and includes a plurality of paddles configured to disperse air from the fan radially outward in a direction perpendicular to a center axis of the fan. In another embodiment, the exhaust system is configured to be mounted to a side wall of the kitchen and to ventilate air from within the hood body through a vertical wall of the kitchen. In one embodiment, the exhaust system is for use in a mobile kitchen.

The present invention discloses a control panel mechanism of a range hood. The control panel mechanism comprises a glass panel (1) and a control component (2), a plurality of mounting plates (4) each having two ends are disposed on the back of the glass panel (1), one end of each mounting plate (4) is connected to the control component (2) by a plurality of first fasteners (6); the mounting plates (4) are detachably connected to a front side plate (31) of a housing (2) of the range hood, and the mounting plates (4) is attached to a top plate (32) of the housing (2) by a second fastener (7). So that it is very convenient to assemble and disassemble the control component.

A combination appliance includes a cooktop having an opening representing a suction opening of the combination appliance. Arranged below the cooktop is a steam extraction device for suctioning air from a space above the cooktop via the opening. The steam extraction device includes a single blower having an air inlet opening and arranged in the combination appliance such that the air inlet opening of the blower faces the cooktop.

A wind outlet mechanism for a range hood comprises a wind outlet and a decorative cover. The decorative cover has a plurality of wind discharge holes, a flow guide member is disposed inside the decorative cover, and the flow guide member has a cambered flow guide surface opposite to and protruding toward the wind outlet. The flow guide surface can make the air flow discharged from the wind discharge holes on the decorative cover.

A heat exchange system for commercial kitchen installations, having a dedicated plenum to receive combustion emissions separate from cooking emissions, where the plenum has a heat exchange structure that efficiently and directly draws heat from the combustion emissions. The plenum heat exchange structure reduces the air volume that a ventilation hood covering the kitchen appliances needs to process and filter, while concurrently obtaining heat from combustion emissions without interference from cooking emission effluents such as grease, smoke, or particulate matter. Heat drawn out of the combustion emissions can be stored in a thermal reservoir for powering other parts of the commercial kitchen or other uses. The diverted airstream from combustion emissions, once passed through the heat exchange structure, can further ventilate through an additional heat exchanger, to provide tempered air to an interior location, such as the commercial kitchen via an air supply duct in the cooking emission ventilation hood.

A cooking engagement system and methods therefore are provided. The system includes a cooktop appliance and an interactive assembly positioned above the cooktop appliance. The interactive assembly includes an image monitor that presents various images and information to a user, e.g., recipes. The system includes an infrared sensor for detecting operation of the cooktop appliance. When the infrared sensor senses a temperature level that exceeds a threshold, a controller communicatively coupled thereto activates an air handler to move or motivate an airflow across or about the image monitor. In this way, the image monitor may be cooled and condensation is prevented from forming on the imaging surface of the image monitor.

A ventilation system for a cooktop appliance comprising a cooktop surface. The ventilation system defines a vertical direction, a lateral direction, and a transverse direction. The ventilation system includes a casing positioned above and spaced apart from the cooktop appliance along the vertical direction with an image monitor supported on the casing at a front end of the casing. The ventilation system is selectively configurable to provide fluid communication from an air inlet to one of a recirculation outlet, a first exhaust outlet, and a second exhaust outlet without removing or rearranging an air handler of the ventilation system.
