In order to heat a bag filled, for example, with a food product to a predeterminable temperature, the entire cassette (1) has been heated in the past. The invention relates to a cassette (1) made of plastic, wherein in each of the cassette shells (2, 3) a receiving recess (10) is formed, in each of which a respective heat-conducting plate (11) is arranged securely in position. A heating element (20) is applied to the heat-conducting plate (11) and the heat-conducting plate (11) is retained in an insulated manner on the respective cassette shell (2, 3) such that a thermal insulating air gap remains between the heat-conducting plate (11) or the heating element (20) and the cassette shell (2, 3).

A portable lunchbox (1) for storing, transporting and preparing food, comprising a food cavity (10) for receiving food; a heating cavity (20) for receiving water; a heating element (80) for heating water in the heating cavity (20); a switch device (50) which can be switched from a first state to a second state; wherein the lunchbox (1) is designed in the first state of the switch device (50) to heat food arranged in the food cavity (10), and in the second state of the switch device (50) to steam food arranged in the food cavity (10). This lunchbox enables various kinds of meals preparation in a simple manner.

A portable carafe has a reservoir (14) for holding a liquid, a hot liquid outlet (18) and a hot liquid flow path (22) connecting the reservoir to the hot liquid outlet. A heater (28) is arranged in the hot liquid flow path so that the heater can heat liquid passing from the reservoir (14) to the hot liquid outlet (18). The heater (28) may be inactive when no liquid is passing through the hot liquid flow path, and may be active only when hot liquid is to be dispensed. The carafe may include a battery (50) for powering the heater. The carafe may include a cold liquid outlet (20) and a cold liquid flow path (34), and may be arranged so that tilting the carafe in one direction causes hot liquid to be dispensed, whereas tilting the carafe in another direction causes cold liquid to be dispensed.

In one embodiment, a method includes, by an electromagnetic device, accessing multiple previously recorded heating maps corresponding to a load disposed inside a cavity, where each heating map indicates a temperature profile change of the load as a function of one or more control parameter configurations, accessing a target temperature profile of the load, measuring a current temperature profile of the load, calculating a difference in temperature profiles between the current temperature profile of the load and the target temperature profile of the load, determining a first sequence of control parameter configurations to heat the load, wherein the first sequence is optimized to yield a temperature rise that achieves the target temperature profile of the load, emitting electromagnetic radiation into the cavity based on the first sequence of control parameter configurations.

A multi-zone food holding bin has a continuous food supporting surface with multiple food holding zones. Each food holding zone is independently controllable so that different food temperatures may be maintained in adjacent food holding zones.

Radiant furniture made of a concrete mix includes one or more heating elements or hot water supplied hydronic tubing that provide comfortable radiant heat. Tabletops can be heated to a temperature that is comfortable for people seated at the table. Benches and seats can be heated to provide comfortable heated seating. Combinations can also be used together, such as a heated tabletop with heated seats. A controller senses the temperature of the furniture and the ambient temperature, then applies power to one or more heating elements in the furniture according to programmed temperature thresholds to provide comfortable radiant heat from the furniture. The controller includes a calibration mode that allows calibrating the controller to a particular heated surface. The controller further comprises a knob that determines an operating mode for the controller and allows adjusting a temperature threshold for the heated surface up or down.
