The cookware of the utility model embodiment is described in detail with reference to Fig. 1 to Fig. 5.
Cookware according to the utility model embodiment may include inner casing 10, shell 20 and conduction material.
Wherein, shell 20 is set in the outside of inner casing 10, and inner casing 10 is connected with shell 20 and between inner casing 10 and shell 20 Limit hollow cavity 30.
Conduction material is arranged in hollow cavity 30, and wherein conduction material can be conduction oil, sand or ceramic grain.Heat conduction object Matter setting may insure that heat more uniformly transmits on inner casing 10 in hollow cavity 30, to which cookware may not necessarily be in inner casing 10 Upper setting non-sticking lining, relying solely on the physics non-adhesion behavior of cookware can achieve the effect that food is not viscous, not paste.
When conduction material is conduction oil, when the bottom to cookware is heated, since the thermal coefficient of conduction oil is high, Therefore conduction oil can quickly absorb heat, temperature quickly increases and temperature is easier to reach unanimity, so on inner casing 10 with lead The part that deep fat is in direct contact can simultaneously and heat is equably absorbed from conduction oil, the temperature for improving inner casing 10 is uniform Property, the temperature of cookware each section is consistent substantially, finally realizes that the cookware surface when cooking there is good physics not glue Effect.
When conduction material is sand or ceramic grain, when the bottom to cookware is heated, due to sand or ceramic grain Thermal coefficient it is relatively low, therefore the transmission heat of sand or ceramic grain is slower, and the temperature of sand or ceramic grain is more uniform, in turn Each section on inner casing 10 can absorb heat simultaneously, and the temperature of each section is more uniform on inner casing 10, on inner casing 10 with sand Or the temperature of the part of ceramic grain contact is consistent substantially, finally realizes that the cookware surface has good physics when cooking Do not glue effect.
In some embodiments of the utility model, conduction material is conduction oil.
Further, the coefficient of expansion of conduction oil is 0.0006m/ DEG C -0.0007m/ DEG C.Thus, it is possible to ensure heat source Heat is rapidly transferred to conduction oil, and the temperature of conduction oil is easier to reach unanimity, so ensure on inner casing 10 with heat conduction The temperature of oily contact portion is evenly distributed state, improves the physics non-adhesion behavior of cookware.
The vapourizing temperature of conduction oil is not less than 260 DEG C, because the maximum heating temperature of general cookware does not exceed 260 DEG C, Therefore the utility model conduction oil can be too low to avoid conduction oil vapourizing temperature and there is vaporization phenomenon, influence leading for conduction oil Hot property and temperature uniformity.
In some embodiments of the utility model, the maximum volume of conduction oil is the 50%- of the volume of hollow cavity 30 90%.The volume of conduction oil is in the range intervals, it can be ensured that and it is more uniform with the portion temperature of food face on inner casing 10, together When ensure more heats for food carry out cooking, promote the utilization ratio of heat.

Further, also there is cookware maximum water level, maximum water level to be higher than lowest water level line, the highest of conduction oil Liquid level is less than or equal to 5mm higher than the difference in height of the highest liquid level and maximum water level of maximum water level and conduction oil.
Since conduction oil is higher than the maximum water level of cookware, even if the amount of cookware cooking is larger, conduction oil The food in inner casing 10 can also be effectively transferred heat to, the part Wen Sheng on inner casing 10 being in direct contact with food is faster And temperature is more uniform, promotes the non-sticky performance of physics of cookware.
In addition, the highest liquid level of the conduction oil of the utility model will not be higher by again, maximum water level is too many, avoids cookware The temperature of upside it is excessively high and cause thin rice gruel be easy overflow the phenomenon that.
In some embodiments of the utility model, conduction material is sand or ceramic grain.
Further, the thermal coefficient of sand or ceramic grain is:0.01w/(mk)-1.0w/(mk).Due to sand or ceramics The heat-transfer rate of grain is more slow, and heat can more slowly be transferred to the various pieces of sand or ceramic grain, sand or ceramic grain Each section temperature it is more uniform, and then the heat one that the part on the inner casing 10 being in direct contact with sand or ceramic grain receives It causes, temperature is also relatively uniform, reduces food and the probability being burned occurs.
Simultaneously because the low thermal conductivity of sand or ceramic grain, after heat stops heating, sand or ceramic grain can be right Food in cookware plays good insulation effect.
In some embodiments of the utility model, the maximum volume of sand or ceramic grain accounts for the 90% of 30 volume of hollow cavity More than.For example, sand or ceramic grain can be full of entire hollow cavity 30.
Certainly, sand or ceramic grain had better not be completely filled with entire hollow cavity 30, to avoid the temperature of the upside of cookware It is excessively high and cause thin rice gruel be easy overflow the phenomenon that.
Cookware has a lowest water level line, and the highest face of sand or ceramic grain is higher than lowest water level line, it may thereby be ensured that pot Tool can carry out effective cooking to food, it is ensured that food can be completed quickly in cooking.
Further, also there is cookware maximum water level, maximum water level to be higher than lowest water level line, sand or ceramic grain Highest face be less than or equal to 5mm higher than the difference in height in the highest face and maximum water level of maximum water level and sand or ceramic grain.
Since sand or ceramic grain are higher than the maximum water level of cookware, even if the amount of cookware cooking is larger, Sand or ceramic grain can also effectively transfer heat to the food in inner casing 10, on the inner casing 10 being in direct contact with food Portion temperature is more uniform, reduces food and the probability being burned occurs.
In addition, will not to be higher by maximum water level again too many in the highest face of the sand of the utility model or ceramic grain, pot is avoided The temperature of the upside of tool it is excessively high and cause thin rice gruel be easy overflow the phenomenon that.
