When first, comparing unit instruction control unit power-off；In the case where being freezed using semiconductor refrigerating part, temperature tester measures temperature
When degree is less than setup unit, comparing unit instruction control unit power-off.
Further say, described control unit also has a conventional setting, described conventional setting refers to control unit
Instruction semiconductor refrigerating part long-time heating in the case of 40 DEG C of temperature.
The beneficial effects of the utility model are：Such lunch box has can both be made the food heating of the inside, can also make
The food of the inside turns cold, meets some desired advantages；
Described semiconductor refrigerating part includes the semiconductor grain welded on matrix and matrix, and described semiconductor grain is used
Silver-bearing copper is welded on matrix, also with semiconductor refrigerating part is durable in use, heating-up temperature is high, can reach 100 DEG C of advantage.
