Description

Pot body and cooking utensils with same

technical field

The utility model relates to the field of kitchen utensils, in particular to a pot body and a cooker with the same.

Background technique

At present, the ordinary pots used in daily households are generally heated at the bottom of the pot, such as electric rice cookers heating pans, woks and soup pots used by various gas stoves. The pot body heated by the heating plate method of the electric rice cooker generates heat through a heating plate at the bottom of the rice cooker, and then conducts heat to the pot body for heating and cooking. Various gas stoves directly heat the bottom of the pot. Therefore, when the common pot body is heated, heat is generally generated at the bottom, and then through the heat conduction of the pot body itself, the heat is transferred to the middle and upper edges of the pot. At present, the materials used in common pots are generally stainless steel, iron, or Aluminum and other materials have relatively low thermal conductivity, such as 304 stainless steel with a thermal conductivity of less than 20W/m.k, pure iron about 70W/m.k, and aluminum with a thermal conductivity of about 237W/m.k. Due to the low thermal conductivity, when the pot is heated, the temperature at the bottom of the pot is higher, while the temperature in the middle and upper part of the pot is lower, resulting in uneven heating of the whole pot. Therefore, this kind of pot is used in rice cookers. Cooking rice will cause the upper layer of rice to be uncooked, and use it in cooking will cause the bottom of the pot to be mushy and the upper layer will be uncooked, which will seriously affect the taste of the food. Therefore, many rice cookers currently use aluminum alloys with high thermal conductivity, and even interlayer copper materials.

Although the iron pan used in the frying pan is beneficial to the human body, its thermal conductivity is low, so it can only be used on high heat or thickening the pan body.
