BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat insulation cover structure, and more particularly, to a heat insulation cover structure applied to an electric pressure cooker.

Generally, the electric pressure cooker is a cooking device in which the inner pot containing the cooking water is forcibly closed and then heated to keep the steam generated in the inner pot from being discharged to the outside. That is, an electric pressure rice cooker refers to a kitchen appliance that shortens the time required to cook food at high temperature and high pressure during cooking and improves the taste of the cooked food.

Such an electric pressure rice cooker is composed of an inner pot containing largely cooked food, a rice cooker body provided so as to sandwich the inner pot, and a lid rotatably installed in the rice cooker body to strongly seal the inner pot when cooking cooked food.

Therefore, when the cooked food is contained in the inner pot and then the inner pot is inserted into the cooker body, the lid strongly seals the inner pot containing the cooked food, and the cooker body heats the inner pot using a heating unit or the like provided therein.

Therefore, steam or the like is generated in the inner pot, so that a state of high temperature and high pressure is achieved, and cooked food contained in the inner pot is cooked in the state of high temperature and high pressure. Then, when the cooked food contained in the inner pot is cooked, the steam inside the inner pot is discharged to the outside and cooking is completed. Therefore, the electric pressure cooker is switched from the cooking mode to the keep-warm mode for storing the cooked food in the cooking mode for cooking the food from this time.

Meanwhile, conventionally, a method of simply keeping the cooked food warm is applied in order to store the cooked food for a long time in the keep warm mode.

However, in this case, the opening and closing of the lid causes the outside air to flow into the inner pot, and the inflow air comes into contact with the cooked food contained in the inner pot, causing discoloration of the cooked food or generating odor.
