A heating profile of a microwave oven is modified using microwaves at a plurality of frequencies. A power of transmission to a cavity of the microwave oven of microwaves is defined at each of the plurality of frequencies. A duration is defined for which the microwaves are transmitted at each of the plurality of frequencies. For each of the plurality of frequencies, a proportion of power input to the cavity that is not output from the cavity is measured. The measured proportions am used to modify the power of transmission at each frequency, the duration of transmission at each frequency or both.

A microwave cooking appliance performs controlled beverage warming using a temperature sensor to capture a thermal image of a beverage in a cooking cavity. One or more sensing locations within the thermal image that are suitable for determining the temperature of the beverage are determined in part by ordering temperature readings from the thermal image by temperature to determine a temperature function and then determining locations in the thermal image that correspond to the beverage by calculating a derivative function over at least a portion of the temperature function.

A transition device for a hollow waveguide comprises a rectangular structure comprising an inlet wall and interior extending from the inlet wall along a longitudinal axis. The inlet wall is configured to receive a transmission line comprising an antenna. The antenna forms a proximal end proximate to the inlet wall and a distal end configured to extend into the rectangular structure of the hollow waveguide. A channel is formed in the rectangular structure. The channel comprises a base forming a tuning surface. The tuning surface is configured to extend along a length of the antenna in a spaced configuration parallel to the longitudinal axis.

A cooking adjustment system for a cooking appliance includes a body that defines a cooking cavity. A steam generator system is coupled to the body. The steam generator system is configured to inject steam into the cooking cavity. An air temperature sensor is disposed within the cooking cavity and configured to sense a dry bulb temperature. A food probe has multiple food temperature sensors. At least one of the food temperature sensors is configured to sense a surface temperature of a food item. A controller is communicatively coupled to the steam generator system, the air temperature sensor, and the food probe. The controller is configured to determine a wet bulb temperature utilizing the surface temperature of the food. The controller is configured to adjust relative humidity within the cooking cavity in response to at least one of the wet bulb temperature and the dry bulb temperature.

A heating cooking apparatus includes a heating cooking unit, a microwave supply unit, an air blowing mechanism, and a fixing member. The heating cooking unit includes a heating cooking chamber. The microwave supply unit is fixed to the heating cooking unit and supplies microwaves to the heating cooking chamber. The air blowing mechanism blows air onto the microwave supply unit. The fixing member is fixed to the heating cooking unit. The air blowing mechanism includes a fan, a motor that drives the fan, and a first attachment member disposed on a side, in a predetermined direction, of the fan. The fixing member includes a support portion that supports the first attachment member, and an attachment portion to which the first attachment member is attached.

A cooking machine includes a microwave heating body, a transferring member for the cooking carrier, a transferring member for dish delivering and a cooking carrier for holding a object. The microwave heating body is moved up and down relative to the cooking carrier, and is correspondingly combined with the cooking carrier to form a heating cavity. The cooking carrier is pivotally arranged on the transferring member for the cooking carrier, and is movable to an initial position and a heating position. A cleaning assembly and a dish delivering member are arranged on the transferring member for dish delivering, and are movable to a position below the cooking carrier by turns. Thereby, the cooking carrier with the object can be cooked when moved to the heating position, and then moved to the initial position and turned to allow the cooked object to fall on the dish delivering member.

An oven appliance with one or more features for directly measuring a temperature of a food item in a cooking chamber of the oven appliance. The oven appliance is also configured to modify operation of at least one of a first heating element, a second heating element, and a convection fan in response to the directly measured temperature of the food item.

An oven appliance includes a controller configured to provide a first prompt and a second prompt. The first prompt and the second prompt each include a selectable range of values for a characteristic of a food item. A cooking cycle is initiated based on a first response to the first prompt and a second response to the second prompt. The cooking cycle includes activating at least one of a first heating element, a second heating element, and a convection fan based on the first response and the second response. Related methods are also provided.

An apparatus configured to apply electromagnetic energy to an object may include an energy application zone adapted to receive at least a portion of an object and a source configured to supply RF energy to the energy application zone. The apparatus may also include at least one processor configured to: cause the source to supply RF energy to the energy application zone; determine a value indicative of a rate of energy absorption by a load, including at least a portion of the object, during a first period of time; and determine, based on the value indicative of the rate of energy absorption by the load, an estimated amount of time to obtain a desired characteristic in at least a portion of the object.

A information processor of a terminal apparatus reads from a memory identification information of a food handling apparatus and a table, identifies a function associated with the identification information of the food handling apparatus received by a information receiver in accordance with the table, and starts up the function.
