A method of controlling a household range hood, comprising: programming a suction device and/or of a further electric load, preferably of a light source, of the range hood through an electronic control unit connected in signal communication to the range hood to schedule a plurality of operation modes and/or a plurality of working times of the suction device and/or of the further electric load during a time period.

An illumination system for a cooking appliance is capable of illuminating generally downwardly onto the cooktop burners of the cooking appliance using multiple illumination schemes. One illumination scheme may be used to indicate which cooktop burner is controlled by a particular burner control that a user is interacting with prior to activation of the cooktop burner, e.g., to indicate to a user that a burner control that the user has touched or is otherwise proximate to controls a particular cooktop burner. Another illumination scheme may be used to indicate which cooktop burner is being adjusted when a user is adjusting a particular burner control, e.g., to indicate to a user that a burner control that the user is currently manipulating is changing the output of a particular cooktop burner.

Embodiments of the invention provide a ventilation system comprising a housing that includes a plurality of panels. At least one socket can be defined through at least one of the panels and the socket can be coupled to an electricity source. In some embodiments, the ventilation system can include at least one illumination system that can include a socket interface, an extension member, and at least one illumination device. The socket interface can be configured to engage the socket and the extension member can be capable of moving in a plurality of directions.

A cooking engagement system for a cooktop appliance is provided herein. The cooking engagement system may include a camera assembly, an image monitor, a lighting assembly, and a controller. The camera assembly may be mounted above the cooktop appliance along a vertical direction and directed at a cooktop surface. The image monitor may be mounted above the cooktop appliance and directed away from the cooktop surface. The lighting assembly may be mounted to the casing above the cooktop appliance. The lighting assembly may include a light source directed at the cooktop source to emit a light thereto. The controller may be in operable communication with the camera assembly and the image monitor to initiate an interactive cooking operation.

A range hood and a method for controlling the range hood are provided. The apparatus includes a range hood which is capable of photographing a cooking process that is being performed on an upper plate of a cook top by using a camera disposed in the main body of the range hood, and a method for controlling the range hood are provided. In some of the example embodiments, a range hood is capable of photographing a cooking process that is being performed on an upper plate of a cook top that is positioned below a bottom surface of the main body.

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.

A high-frequency heating device with a range hood is equipped with a heating chamber, a magnetron for supplying high-frequency power, a chamber illumination device disposed adjacent, from outside, to a wall of the heating chamber, and an LED illumination device which is disposed in a bottom portion of the main body and illuminates a heat-cooking device. The LED illumination device uses light-emitting diode elements, and illumination light emitted from the LED illumination device is concentrated by a reflection plate whose surface is plated.

The present invention provides a high-tech stove fire detector and suppression system comprising an exhaust hood and a stove unit with multiple burners on a cooktop. The exhaust hood includes an overhead unit with fire extinguisher nozzles to combat fires on the cooktop. Sensors detect smoke or fire, while the stove unit has a sensor for detecting the presence of a person within a 10-foot range. The system also features LED lights with video cameras, a ventilation display with an emergency turn-off button, and four power outlets. A mobile application allows remote control of the system, including burner and oven controls. This invention offers an efficient solution for fire detection, suppression, and remote management in any kitchen.

According to an aspect of the present disclosure, a ventilation system includes at least one user directed component and a plurality of sensors configured to detect a plurality of control gestures within a gesture field designated for presentation of control gestures by a user. The ventilation system may further be configured such that a control gesture of the plurality of control gestures is presented within the gesture field for detection of said control gesture by the plurality of sensors, and the plurality of sensors recognizes the control gesture as corresponding to an operation of the at least one user directed component. The ventilation system may still further include a controller for polling the plurality of sensors and converting a recognized control gesture to a command signal for operating the at least one user directed component.

The present disclosure relates to a hood (1) for domestic use, which comprises a support frame (10) with a power input (11), a motor fan unit (20) located within said support frame (10), lighting means (30), fixing means (40) for removably fixing said lighting means (30) to said support frame (10), and electric connection means (60) for electrically connecting said lighting means (30) to said power input (11). The hood is characterized in that said lighting means (30) comprise an enclosure (33) that defines a seat (33a) containing a plate (32) having a plurality of LEDs (31), and are movable relative to said support frame (10) between a first position, in which said electric connection means (60) electrically connect said lighting means (30) to said power input (11) and a second position, in which said lighting means (30) are electrically disconnected from said power input (11), wherein said electric connection means (60) are configured to electrically disconnect said lighting means (30) from said power input (11) directly, once said lighting means (30) have moved from said first position to said second position.
