In China, the requirements of the public on catering food are meat and vegetable matching and complete color and flavor, which means that the requirements on fresh-keeping storage and secondary heating treatment of the catering food are higher. At present, for carrying catering food, diners mostly take the traditional lunch bag and the lunch bag with single refrigeration function as main carrying tools. Because the traditional lunch bag generally adopts the principle of physical heat insulation and does not have the functions of preserving freshness and secondarily heating the food, the food is easy to deteriorate when being stored for a long time or the taste and the health of the food are influenced when being taken. Most of the conventional lunch bags with the functions of refrigerating and refreshing food in the market utilize ice bags or a physical cooling mode of enhancing the airtightness of the lunch bags by adopting special materials to realize the refrigeration and refreshing of the food. When the lunch bag is used, the food can be refrigerated and kept fresh only in a short time, and the carried food cannot be heated when a diner has a meal, so that the diner can only eat cold meal to influence the body health of the diner, or the diner needs to heat the food by using other cookers, thereby wasting time and labor.

In the heat preservation mode, the driving controller (A2) reads the temperature of the inner space of the bag body (A6) through the temperature sampling unit (A4) and compares the temperature with a set temperature, and the difference determines the driving current direction of the driving controller (A2) to the semiconductor cold-hot plate (A5), so that the semiconductor cold-hot plate (A5) is in a heat-generating temperature-rising or cooling state. The difference value between the temperature of the inner space of the bag body (A6) and the set temperature is taken as a target to be zero by adopting a control algorithm of intelligent approximation. In the above two operation modes, the preset temperature can be freely set within an allowable range.
