Description

Easy-to-clean cooking appliance and rice cooking method Technical Field The application belongs to the technical field of kitchen appliances, and particularly relates to an easy-to-clean cooking appliance and a rice cooking method. Background The cooking utensil adopts the dish that generates heat to heat the food in the inner bag generally, and in the culinary art in-process, the inner bag needs to be in contact with the dish that generates heat, and the dish that generates heat heats the inner bag through the mode of contact heat transfer promptly. At present, some electric cookers which are not sticky are realized by cooling the inner container without arranging a coating, and before cooking is finished, cold air is blown to the outer wall of the inner container to cool the inner container, so that a water film is formed between the inner container and food, and food stickiness is reduced. The cooling mode is to blow the air of the fan to the outer surface of the inner container to cool the inner container, and when the air blown by the fan just contacts with the surface of the inner container, the cooling effect is better because the temperature of cold air is lower. However, as the contact time between the air flow and the liner is gradually increased, the cold air is continuously heated when flowing through the outer surface of the liner, the temperature is gradually increased, and when the air flow flows to the other side of the liner, the temperature of the air flow is higher, and the cooling effect on the liner at the side is reduced. Therefore, in the whole cooling air duct, the upstream cooling is fast, the downstream cooling is slow, and the temperature difference at two sides of the liner is larger and larger along with the continuous cooling stage.
