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.

A radiant heater device includes: a heater main body having a heating portion that generates heat by being supplied with electric power to radiate radiation heat due to the heat supplied from the heating portion; an output control unit that controls an output of the heating portion; and a maximum output determination unit that determines an upper limit of the output of the heating portion depending on a heat load around the heater main body. The output control unit controls the output of the heating portion depending on the heat load not to exceed the upper limit of the output determined by the maximum output determination unit.

A radiant heater device has an electrode embedded in a substrate part and a plurality of heating parts. The electrodes are formed by material that has low specific resistance. An area occupied by the electrode is restricted. The heating parts are formed by material having high specific resistance in order to generate heat so that radiation is produced. The electrode and the heating part are electrically connected within the substrate part. The plurality of heating parts are arranged in parallel between a pair of electrodes. The electrodes and the heating parts are formed in a film-like shape, and the thermal capacity is reduced. As a result, a temperature of the heating parts rises promptly in response to a turning on of power. In addition, the temperature of the heating parts promptly decreases when an object comes into contact therewith.

A range has burner coil elements which have temperature switches as a portion of the replaceable coils. Upon reaching a predetermined temperature, the switch opens and power through the burner element is secured. The burner elements are preferably open coil units. Lowering the temperature in a cooking utensil below common ignition temperatures while still allowing boiling is an objective of many embodiments.

Several embodiments include a cooking instrument. The cooking instrument can include a heating system. The heating system can include one or more heating elements capable of emitting wireless energy into the cooking chamber. The cooking instrument can also include a control system. The control system can determine a heating sequence (e.g., logical instructions) to drive the heating system. The control system can then execute the heating sequence. The heating sequence can include an instruction to adjust, based on a trigger event detectable by the control system, the spectral power distribution of wireless waves emitted from a heating element in the heating system.

The present invention is directed to a multi-heat source fire pit apparatus. The fire pit apparatus is configured to provide ambient heating with both convection heat transfer and radiation heat transfer. The multi-heat source fire pit apparatus comprises an infrared emitter for generating infrared radiation. The multi-heat source fire pit comprises a shielding member between a heat source for the convection heat transfer and another heat source for radiation heat transfer.

A combined housing for temperature control of a space has a top face, a bottom face, a left side face, a right side face, a front face, and a rear face. A heating assembly formed in the housing has a recess centrally positioned in the front face and a radiant heating element extending laterally within the recess. A cooling assembly formed in the housing has an input aperture formed in the rear face equally spaced from the left and right side faces, a first output aperture formed in the front face between the recess and the left side face, and a right output aperture formed in the front face between the recess and the right side face.

Heating louvre (11) for a louvred roof comprising at least two girders which extend parallel to each other and to which several louvres are rotatably connected between an open position and a closed position. The heating louvre (11) is provided with an underside (13). A slot is provided in the underside (13) for fitting a heating element (12) inside the heating louvre (11). After the heating element (11) has been fitted, the cavity (15) is at least partially sealed by it and the heating element (11) is provided to heat a position between the louvred roof and the ground surface by means of radiant heat. By using a slot in combination with a heating element (12) based on radiant heat, it is possible to heat the position between the louvred roof and the ground surface, as the heating element (12) is not fully surrounded by the heating louvre (11).
