Description
Technical field
The present invention relates to a kind of samming cookware of pot bottom containing vacuum chamber, belong to soaking cookware field.
Background technology
At present can the material of electric cooker or inner tub of pressure cooker be generally aluminium alloy or aluminium alloy/stainless steel clad plate, they
Mainly by spraying PTFE (Teflon) etc. in internal layer aluminium surface, stickness paint does not realize its surface during cooking not
It is stained with effect.But these non-sticky coating wear resistances are poor, are easier to come off, may be to the body of consumer after being absorbed by the body
Body health generates security risk.The companies such as profit Tang electric appliance for thus having Datong District's electric appliance in Taiwan, Shenzhen develop electric hot tray heating
The uncoated liner pot of health, reach certain non-sticky effect of physics by carrying out control to temperature of boiler.Since interior pot heats
The influence of temperature distribution evenness, uncoated cookware bottom is heated when comparing concentration, and the non-sticky effect of physics in the bottom of a pan is poor, rice
It is easy to stick in the bottom of a pan and the paste also more difficult cleaning at this.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of samming cookware of pot bottom containing vacuum chamber, overcome existing skill
Heating temperature is unevenly distributed and increases non-sticky coating and prevent viscous pot from causing cannot there are security risk and heat in order to prevent in art
The defects of efficiently using.

Include pot bottom wall and be connected to the pot side wall of four side of pot bottom wall, the pot side wall include the first pot side wall and
Have in the second pot side wall being connected with the first pot sidewall upper, the first pot side wall and the pot bottom wall
Interconnected vacuum chamber, have in the vacuum chamber in the pot bottom wall heated can be converted into gaseous liquid phase-change from liquid
Working medium, the vacuum chamber of the first pot side wall is interior to have liquid-sucking core.
The beneficial effects of the invention are as follows：The present invention due in the vacuum chamber of the first pot side wall have liquid-sucking core,
It heats outside to pot bottom wall, after liquid refrigerant in the vacuum chamber in heat pot bottom wall, volatilizing immediately is
Gas and top (condensation end) diffusion for being transmitted to the vacuum chamber of the first pot side wall, at the same time with the biography of heat
It leads；And the working medium after being cooled occurs condensation and is changed into liquid, and flow to along thermal conductive cavity in the vacuum chamber in pot bottom part, again
It evaporates by heat, so moves in circles, ensure the temperature field base of entire the bottom of a pan bottom wall and the first pot inside sidewalls different position
Originally it is consistent.
During conventional culinary, during due to cooking food, the capacity of food is predominantly located in pot below maximum stage line
Region, thus be even more important by controlling the uniform distribution of the temperature field height of cookware middle and lower part position, the present invention is by right
Side middle and lower part temperature field is precisely controlled in compound pot body containing vacuum chamber, ensures that internal layer pot different zones are heated evenly, from
And realizing it has the non-sticky effect of good physics during cooking and improves heating efficiency.
