The bottom of the heating container 100 is heated, the liquid phase change working medium 3 in the interlayer cavity is vaporized, and due to the temperature difference between the upper part and the lower part of the heating container 100, the gaseous phase change working medium is pushed to rise in the interlayer cavity and is condensed at the lower upper part of the interlayer cavity, so that the heat is rapidly conveyed to the upper part of the heating container 100. In order to achieve a good continuous heat transfer effect, the condensed liquid phase change working medium 3 needs to quickly return to the heating end at the bottom of the heating container 100 to transport heat again, but because the temperature of the lower end of the cavity is higher than that of the upper end, the efficiency of liquid backflow under the action of gravity is very low, and the continuous heat transfer effect of the heating container 100 is seriously affected.

In addition, the micropore channel has a larger specific surface area, so that gaseous phase change working medium can be rapidly condensed into liquid phase change working medium 3 on the surface wall micropore structure 4, and the gas-liquid phase change cycle conversion rate of the liquid phase change working medium in the interlayer cavity is further accelerated; the lower wetting part can accelerate the vaporization of the liquid phase change working medium, thereby further accelerating the heat conduction efficiency of the heating container. Thus, the heating rate of the food material in the heating container is correspondingly increased, and a better cooking experience is given to a user.
In addition, the inner sidewall of the outer case 1 and/or the outer sidewall of the inner case 2 are integrally formed with the surface wall microporous structure 4, so that structural stability and reliability between the surface wall microporous structure 4 and the pot wall can be improved, and the part assembly process and the mold manufacturing cost of the heating container 100 can be reduced.

Wherein, the surface micropore channel is formed on the surface of the surface wall micropore structure 4, the internal micropore channel is formed in the surface wall micropore structure 4, and the internal micropore channels are communicated with each other. The communicated microporous channels can promote the adsorption and condensation of the gaseous phase-change working medium and then promote the backflow of the condensed liquid phase-change working medium 3, thereby being beneficial to the supplement of the liquid phase-change working medium 3 at the heating end position at the bottom of the heating container 100.
Further, the surface-wall micro-porous structure 4 may be at least one of an etched micro-porous structure, a sand-blasted micro-porous structure, a micro-arc oxidized micro-porous structure, and a hard oxidized micro-porous structure formed on the surface of the pot wall. Of course, the surface wall microporous structure 4 may also be made by other methods, and the present invention is not limited thereto.

Of course, the surface wall microporous structure 4 may also be made by other methods, and the present invention is not limited thereto.
Optionally, the internal pore diameter R of the internal pore channel may satisfy: r is more than or equal to 6.5 mu m and less than or equal to 270 mu m. Thus, compared with the surface microporous channel, the inner microporous channel has a larger channel surface area, which can further increase the condensation rate of the gaseous phase-change working medium at the upper microporous part 41 and increase the vaporization rate of the liquid phase-change working medium at the lower wetting part 42. And, compare in surperficial micropore passageway, the inside micropore passageway of small-size aperture still has certain capillary suction effect, and liquid phase change working medium 3 after the condensation flows back to the liquid phase change working medium of intermediate layer chamber bottom through the capillary force of inside micropore passageway fast, and the liquid phase change working medium after the condensation can flow back to the heating end of shell body 1 fast and carry out the reheating vaporization promptly. Specifically, in the internal micropore channel, the liquid phase change working medium 3 infiltrates the channel peripheral wall of the internal micropore channel, and the liquid phase change working medium 3 is diffused at a small number of positions in the internal micropore channel by pulling the surface tension of the liquid phase change working medium 3, so that the condensate of the upper micropore part 41 flows back to the bottom heating end of the heating container 100 which has evaporated liquid, the gas-liquid phase change circulation in the interlayer cavity is accelerated, and the heat conduction efficiency of the heating container 100 is improved.
Further, in table wall microporous structure 4, the intercommunication microporous channel of inside microporous channel is more, and inside channel surface area is big more, and inside microporous channel's capillary is stronger, more is favorable to accelerating the gas-liquid phase transition circulation in the intermediate layer chamber, promotes heating container 100's heat conduction efficiency. Therefore, on any cutting plane of the surface wall microporous structure 4, the ratio of the sum of the cross-sectional areas of the inner micropores to the cutting area of the surface wall microporous structure 4 is S1: s1 is more than or equal to 50% and less than 100%, wherein the cutting plane is a parallel plane of the outer wall cutting plane of the outer pot at any point of the outer wall surface of the outer shell 1. It should be noted that the sum of the cross-sectional areas of the internal micropores is the sum of the hollow cross-sectional areas of all the internal micropores of the internal micropore passage on the cutting plane, and the cutting area of the surface-wall micropore structure 4 is the sum of all the cross-sectional areas of the surface-wall micropore structure 4 on the cutting plane. Furthermore, there are numerous points on the outer wall surface of the outer casing 1, and there is an outer pot outer wall tangent plane at any point of the non-edge position of the outer wall surface of the outer casing 1, that is, there are numerous outer pot outer wall tangent planes on the outer wall surface of the outer casing 1; and the parallel plane of the tangent plane of the outer wall of the outer pan has countless, the microporous structure 4 of the surface wall can have countless intercepting areas, on the intercepting plane of any microporous structure 4 of the surface wall, S1 meets the following requirements: s1 is more than or equal to 50% and less than 100%.
Optionally, in order to facilitate the upward flow of the gaseous working medium in the interlayer cavity and the benign gas-liquid phase change circulation in the interlayer cavity, the gap width W of the interlayer cavity is not set too small. Optionally, in order to enable the gaseous working medium to diffuse upwards more rapidly to accelerate the conversion rate of the gas-liquid phase change cycle, the minimum gap width W of the interlayer cavity is not less than 1mm on the horizontal cross section passing through the upper micro-hole part 41. Wherein W as indicated in fig. 3 and 5 may be, for example, the minimum gap width W of the interlayer cavity.
Further, since the surface-wall microporous structure 4 is integrally formed directly on the pot wall, in order to ensure sufficient strength of the pot wall and a reasonable pot wall thickness, the maximum thickness T1 of the surface-wall microporous structure 4 may be not more than 50% of the thickness T2 of the formed pot wall integrally formed with the surface-wall microporous structure 4. Note that, for example, when the surface-wall microporous structure 4 is formed on the pot wall of the outer casing 1, the thickness T1 of the surface-wall microporous structure 4 may be, for example, the designation T1 in fig. 3 and 5, and the thickness T2 of the formed pot wall of the outer casing 1 may be, for example, the total thickness of the pot-wall body of the outer casing 1 and the surface-wall microporous structure 4 shown in fig. 3 and 5.

Note that upper micropores 41 may be formed in a regular ring shape so as to cover the pot wall of heating container 100, upper micropores 41 may be formed in an irregular shape so as to cover the pot wall of heating container 100, and the thickness of upper micropores 41 may be different at each position other than the irregular shape of the cover.
Further, in order to make the heated area of the liquid phase change working medium 3 located at the bottom of the heating container 100 larger, the lower infiltration part 42 can fully cover the top surface of the bottom wall of the outer shell 1, so, the micropore channel and the liquid phase change working medium 3 can fully contact to transfer heat, thereby the liquid phase change working medium can fully absorb heat and quickly vaporize, further, the liquid for preventing condensation backflow is adsorbed in the micropore structure and cannot flow back to the bottom, the backflow speed of the liquid phase change working medium 3 is improved, the phase change heat transfer efficiency of the liquid phase change working medium 3 is improved, and the heat transfer efficiency of the heating container 100 is greatly improved.
Optionally, when the outer shell 1 is integrally formed with the surface wall microporous structure 4, a ratio S3 of a coverage area of the surface wall microporous structure 4 on the inner side wall of the outer shell 1 to an area of the inner side wall of the outer shell 1 satisfies: s3 is more than or equal to 20 percent and less than or equal to 100 percent; alternatively, when the surface wall microporous structure 4 is integrally formed on the inner housing 2, the ratio S4 of the coverage area of the surface wall microporous structure 4 on the outer side wall of the inner housing 2 to the area of the outer side wall of the inner housing 2 satisfies: s4 is more than or equal to 20 percent and less than or equal to 100 percent. Therefore, gaseous phase change working medium can be quickly condensed in the interlayer cavity and the heat can be quickly conveyed to the upper part of the heating container 100, and the liquid phase change working medium 3 condensed by the upper micro-hole part 41 can be quickly returned to accelerate the gas-liquid phase change circulation conversion rate of the liquid phase change working medium 3 in the interlayer cavity.
Further, in order to increase the heated area of the liquid phase change working medium 3 located at the bottom of the heating container 100, the lower wetting portion 42 can fully cover the top surface of the bottom wall of the outer shell 1, so that the microporous channel and the liquid phase change working medium 3 can fully contact to transfer heat, and the heat transfer efficiency of the heating container 100 is greatly improved. In the case of the heating container 100 in which the heating end extends upward along the pot wall, in order to further improve the heat transfer efficiency of the heating container 100, the upper micro-hole 41 may extend upward along the inner sidewall of the outer case 1 and the maximum height of the upper micro-hole 41 is not lower than 1/2 of the height H of the heating container 100. Thus, the heat conduction efficiency of the heating container 100 can be improved, and the heating rate of the food material can be correspondingly improved, thereby providing a better cooking experience for the user.
