A portable food warmer and cooker includes a housing having a base, a plurality of insulated sidewalls, and a latching lid. A food tray is removably securable within the interior volume of the housing. A heating coil is disposed within the interior volume of the housing such that it surrounds the food tray. The heating coil includes an inlet connector and an outlet connector, each of which extend exteriorly through one of the sidewalls of the housing. A pair of heater hoses connect the heating coil inlet and outlet to corresponding inlet and outlet connectors of a coolant system of a motor. The liquid coolant flows through the heater hoses and the heating coil, which transfers heat to the interior volume of the food tray. The device reaches high temperatures such that it can be utilized to cook raw foods utilizing the motor coolant liquid as a heat source.

The present disclosure relates to an induction heating device and a method for controlling the same. In accordance with the present disclosure, first, inductive sensing is periodically performed to detect a specific object with inductive heating property. Next, current sensing of the specific object having the inductive heating property is performed to again check whether the specific object has the inductive heating property. Thus, when the user simply places the loaded object on the device, the device may allow the user to quickly and intuitively confirm whether the corresponding loaded object has the inductive heating property.

A non-electric heating apparatus with an upper and lower section. The upper section includes a cupholder and surrounding upper reaction chamber with dry reaction materials therein. The lower section includes a lower housing, a lower outer shell with lower outer shell apertures, a lower inner shell with lower inner shell apertures, a lower reaction chamber with dry reaction materials surrounding the lower housing, a platform within the lower housing, a bladder containing water on the platform, and bottom. The platform is movable within the housing and the lower outer apertures are structured to rotatably align with the lower inner apertures. Water may be expelled from the bladder into the upper reaction chamber when the platform is moved within the lower housing. The upper reaction chamber produces an exothermic reaction when water enters. The lower reaction chamber creates an exothermic reaction when airflow enters through the aligned inner and outer apertures.
