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 invention discloses a lifting mechanism for a moving component of a range hood and a range hood with the same, which comprises a mounting frame, a moving component, a motor, a transmission mechanism, two lifting rods, a connecting member and two guide rails. The transmission mechanism moves the connecting member up and down along the guide rails, so that the lifting rods and the moving component are allowed to move up and down. The power for the lifting motion is provided by the transmission mechanism, the guide rails on two sides ensure the stability of the lifting motion, and the lifting rods fixed on two sides of the connecting member further transfers the motion downward to the smoke guide plate, so that the lifting motion of the smoke guide plate is very stable.

A cooking appliance apparatus includes a fan unit, a sensor unit designed to detect an electrical fan parameter of the fan unit, a filter unit allocated to the fan unit, and a control unit designed to determine a filter parameter of the filter unit in dependence upon the fan parameter.

Disclosed herein is a cooking apparatus having an improved drainage structure. The cooking apparatus includes a main body having a cooking chamber with an opening provided to be opened forward, and a door coupled to the main body so as to open and close the cooking chamber. The door includes a door frame, a cover glass arranged on a front surface of the door frame, a touch panel arranged between the cover glass and the front surface of the door frame and provided to be in close contact with the front surface of the door frame by being pressed by the cover glass, and a drain hole arranged at a region, corresponding to a lower end of the touch panel, of the front surface of the door frame, and provided to allow a front surface and a rear surface of the door frame to communicate with each other.

Filter assemblies are described. In particular, a filter securement assembly for receiving and retaining a filter media in an exhaust hood includes a main panel defining a first end and an opposed second end, a first retainment surface adjacent the first end of the main panel, a first retainment lip adjacent the first retainment surface, a second retainment surface adjacent the second end of the main panel and a second retainment lip adjacent the second retainment surface.

A portable hood may include a base, a head, a column, and a fan. The head may introduce air thereinto and discharge the introduced air to the outside. The column may be coupled eccentrically to a side of the head in a horizontal direction. Further, the fan may be located inside of the head such that the fan is eccentric to the head toward the column.

A cooking device includes a cooking chamber wall delimiting at least partially a cooking chamber for receiving food to be cooked. A fan generates a cooling air flow for cooling an outer side of the cooking chamber wall such as to produce an intake region, in which there is a negative pressure in relation to a surrounding area, and a blow-out region, in which there is an excess pressure in relation to the surrounding area. A short-circuit device generates a short-circuit air flow between the blow-out region and the intake region, thereby generating a pressure-neutral region. The cooking chamber wall has a vapor outlet in communication with the cooking chamber for discharging vapor from the cooking chamber into the pressure-neutral region.

An air purifier (100) includes a housing (400) formed with an air duct (401), an ozone generation device (20), an activated carbon purification unit (80), and a fan (200) arranged in the air duct (401). The air duct (401) includes an air inlet (402) and an air outlet (403). The air outlet (403) is disposed indoors. The ozone generation device (20) and the activated carbon purification unit (80) are arranged in the air duct (401) along the direction of the air inlet to the air outlet (403), and the ozone generation device (20) is used to generate ozone. The fan (200) is used to suck gas from the air inlet (402) during operation and let the gas pass through the ozone generation device (20) and the activated carbon purification unit (80) to be discharged from the air outlet (403) into the room.

A method and system to treat cooking emissions (e.g., smoke) employs a nanosecond high voltage pulse generator and a transient pulsed plasma reactor. The system is used in a scheme that substantially reduces particulate matter produced in commercial charbroiling processes (e.g., cooking of hamburger meat). Both a reduction in the size distribution and total particulate mass is achieved using the method and system described herein.
