Description

technical field [0001] The invention relates to the field of food heat preservation and heating, in particular to a food heat preservation box. Background technique [0002] Food incubators are often used in catering places such as canteens and hotels. Although the existing food incubators have the function of keeping warm and heating food, because the food incubators are generally large in size, the heating effect is often uneven when heating and keeping food. It is easy to cause uneven temperature inside and outside of the food, resulting in one cold and one hot problem. Sometimes heating for too long will easily evaporate the water in the food, causing the food to dry out, which greatly affects the taste of the food when tasting it. [0003] Some food incubators have complex structures, a large number of buttons, and low intelligence. It is not easy for users to get started quickly, and the operation is also inconvenient. Sometimes, safety accidents may occur due to opera...
