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.

In one embodiment, a method includes determining, by a computing device, a location of a source of air contamination associated with a heating element and determining, based at least on the location of the source of air contamination, at least one of an optimal venting location or an optimal venting size of at least one vent of a venting system. The method further includes at least one of: (1) automatically adjusting a respective current location of the at least one vent of the venting system to a respective subsequent location based on the determined optimal venting location; or (2) automatically adjusting a respective current size of the at least one vent of the venting system to a respective subsequent size based on the determined optimal venting size.

A portable range hood and/or a method of controlling the same may be provided. A portable range hood may include: a wireless power receiver, a communication interface; a driving unit; at least one filter; and at least one processor, wherein the at least one processor may be configured to, based on the wireless power receiver being located in a first cooking zone from among the plurality of cooking zones, receive power from the wireless power transmission device, and activate the communication interface, control the communication interface to receive, from the wireless power transmission device, an operation command generated based on state information of the cooking appliance located in a second cooking zone from among the plurality of cooking zones, and control the driving unit to set at least one of whether to perform the draw-in operation, a strength of the draw-in operation, and a duration time of the draw-in operation, based on the operation command.

The present disclosure discloses a table top range hood, including a duct housing having an air inlet, the air inlet facing a first orientation; a light-transmitting cover, the light-transmitting cover being connected to the duct housing and defining an accommodation cavity together with the duct housing; and a light-emitter disposed in the accommodation cavity, light emitted by the light-emitter being adapted to pass through the light-transmitting cover and irradiate towards the first orientation.

The present invention discloses a portable range hood comprising a barrel-shaped master body, a fan assembly, a first filtration device, and a detachable second filtration device. The body has an air inlet at one end and an air outlet at the other, with a first connection device arranged at the outlet. The fan assembly inside the master body is configured to draw oil fume through the inlet and discharge it through the outlet. The first filtration device is fixed at the inlet, while the second filtration device is mounted at the outlet and provided with a second connection device that mates with the first connection device to enable detachable connection. The detachable second filtration device allows users to flexibly adjust filtration and purification capacity and permits quick replacement without hand contact with oily filters, thereby making the portable range hood simple, convenient, and comfortable to use.
