[0002] 1. The existing mandarin duck hot pot with compartments in the inner cavity of the pot is generally heated from the bottom of the pot upwards. The inner cavity of the pot is generally divided into at least two compartments, and some have three or four compartments. When heating and cooking food, each compartment is boiled and heated at the same time. If the compartment is not used, the water can only boil there, which will generate a lot of steam and a lot of heat. People who eat by the pot feel very hot and uncomfortable. All compartments are heated and boiled at the same time, and no compartment can be used to preheat or precook food. When heating and cooking food, the food sinks to the bottom of the pot. When making soup, boiling soup, or hot pot, some sticky food is easy to stick to the bottom of the pot (stick to the bottom) and burn. When making soup, boiling soup, or hot pot, if the food is not stirred for a long time, it will also be easy to stick to the bottom of the pot and burn.

The central cavity 21 and the outer ring cavity 22 form a double-boiled pot cavity 2, which can be used at the same time to make hot pot, boil soup, and stew soup with different flavors. The outer ring cavity 22 can also be used for preheating or precooking of food, and can also prevent the food at the bottom of the outer ring cavity 22 from sinking and burning or sticking.
