Heat retentive food servingware with temperature self-regulating phase change core

A heat-preserving, temperature self-modulation's food and device (10) comprises one body (12), heat-preserving the core (14) and a magnetic induction heating element (16). A main body (12) comprises, and a defined a cavity (24) food contact wall of the basic rigid, a heat-conducting plate (18). The core (14) is arranged on the cavity (24), and a wall (18) heat conducting contact, so that the number of for selecting to heating the plate (18). The core (14) comprises a solid phase change material, a storing and realizes solidly in a conversion temperature is not phase change the heat latent in process. The elastomer material for phase change material contact, a licence phase change material, and phase in process the. Heating the component (16) and a core (14) heat conducting contact, an inner core (14) is heating is higher than the conversion temperature temperature, wherein the phase in the phase equipments. The component (16) comprises in response a magnetic field ferromagnetic material, in order to heating the component in the component (16) sensing current (16). The Curie temperature of ferromagnetic material is situated between the phase conversion temperature and detector of fusion of material. The food heat insulation device (42) comprises a heater (44); the heater is a support (46) and magnet field generator (48) and rising detector (50) and is located on the support (46) is food perforation the device (10).
