Description

technical field [0001] The invention relates to the technical field of daily necessities, in particular to a refrigeration and heating integrated lunch box. Background technique [0002] Office workers, students often need to bring meals when they go to school or take care of patients. The existing common lunch boxes are only used to hold food such as meals. The function of the heated lunch box is limited to heating. This kind of lunch box is also suitable for heating meals in winter, but the effect of using this kind of lunch box with rice in summer is the same as that of ordinary lunch boxes. When the temperature is high in summer, if There is no refrigerator available, and the use of existing lunch box products to bring meals will easily cause the food in the lunch box to deteriorate. [0003] Semiconductor cooling chip, also called thermoelectric cooling chip, is a heat pump that does not require any refrigerant, can work continuously, has no vibration and noise during ...
