Devices, systems, and methods for maintaining convection heat within a heating region of a griddle and channeling the convection heat therefrom. The griddle includes a ribbing structure along its underside surface in a configuration that cooperates with the burners of a cooking station. Such ribbing structure allows a user to control the convective heating of the griddle as desired and channels the convective heat to a single side of the griddle, away from the user.

In accordance with one embodiment of the present disclosure, a cooking apparatus includes a casing, a cooking chamber formed inside the casing, a duct member formed outside the cooking chamber to extend from a first plate of the cooking chamber to a second plate forming an upper surface of the cooking chamber, a heater installed inside the duct member, and a fan installed inside the duct member and configured to blow air in the duct member, wherein the cooking chamber is formed to cook food using high-temperature air discharged into the cooking chamber through a first outlet part formed at the second plate.

An oven includes a plurality of walls, a fan, and a heating element. The plurality of walls defines an internal cavity in which food may be placed for cooking. A first of the plurality of walls defines a plurality of orifices that establishes fluid communication between the internal cavity and a fluid path. The fan is configured to direct air from the fluid path, through the plurality of orifices, and into the internal cavity. The heating element is disposed on the first of the plurality of walls and adjacent to the plurality of orifices. The heating element is configured to heat the air being directed from the fluid path, through the plurality of orifices, and into the internal cavity.

In accordance with one embodiment of the present disclosure, a cooking apparatus includes a casing, a cooking chamber formed inside the casing, a duct member formed outside the cooking chamber to extend from a first plate of the cooking chamber to a second plate forming an upper surface of the cooking chamber, a heater installed inside the duct member, and a fan installed inside the duct member and configured to blow air in the duct member, wherein the cooking chamber is formed to cook food using high-temperature air discharged into the cooking chamber through a first outlet part formed at the second plate.

The present application discloses a cooking device, which includes a cabinet; the cabinet includes an inner cavity, a first heating assembly and a second heating assembly; the inner cavity is provided with a cooking chamber, as well as a first side wall and a second side wall that are arranged opposite to each other, the first side wall is provided with a first ventilation structure, and the second side wall is provided with a second ventilation structure; the first heating assembly is arranged outside the inner cavity and arranged corresponding to the first ventilation structure, and is configured to circularly heat air in the cooking chamber; the second heating assembly is arranged outside the inner cavity and arranged corresponding to the second ventilation structure, and is configured to circularly heat the air in the cooking chamber.

A method of detecting anomalies of a fan within an appliance includes receiving, at a service computer and/or remote server, data indicative of usage of the fan, analyzing the data indicative of usage of the fan with a machine learning model on the service computer and/or remote server, and flagging the fan for replacement when the machine learning model detects an anomaly in the data indicative of usage of the fan.

A method for processing articles using a microwave heating system includes obtaining an operating profile for heating a type of article using the microwave heating system. The operating profile includes a temperature-time profile for a target F.sub.0 value and a group of set point values for achieving the temperature-time profile, the group of set point values including a target for a control parameter of the microwave heating system. Using a control system operatively coupled to the microwave heating system, the microwave heating system is operated in accordance with the group of set point values such that each of the articles achieves an F.sub.0 value that is greater than or equal to the target F.sub.0 value.

An embodiment of a heating system includes a cavity configured to contain a load, a thermal heating system, and an RF heating system. The RF heating system includes a system controller, an RF signal source, one or more electrodes that receive an RF signal from the RF signal source and radiate resultant electromagnetic energy into the cavity, and a variable impedance matching network coupled between the RF signal source and the one or more electrodes. The system controller may monitor an impedance state of the variable impedance matching network to identify the occurrence of a change point. The system controller may estimate the mass of the load and a time and/or energy requirement for cooking the load based on the change point. The system controller may take action by turning off the RF heating system and/or thermal heating system when the time or energy requirement has been met.

A cooking appliance having a main body provided therein with a cooking space, a rack formed on a lateral wall of the cooking space, a door configured to open and close the cooking space, and a storage vessel which is held in the rack and in which a food item is placed. The storage vessel may include a first piece having a plurality of removing holes in a portion, in which a food item is placed, in transverse and vertical direction, and at least one bent portion on an edge thereof, a second piece onto which the first piece is mounted, and which has a bent portion at a position corresponding to the bent portion of the first piece, and an insulating member made of an electrically insulating material, disposed on an edge of the first piece, and disposed between the first piece and the second piece.

A method of operating a cooking appliance includes receiving, by a controller of the cooking appliance, an input indicating that the cooking appliance is to operate in a meal cook cycle. The method also includes activating at least one heater module of a plurality of heater modules during the meal cook cycle. The method also includes activating a motor to rotate a turntable through a complete revolution within the cooking cavity. The turntable is rotated at a first speed during a first portion of the complete revolution and at a second speed different from the first speed during a second portion of the complete revolution.
