Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a soaking pot with a multi-layer liquid-absorbing core, which overcomes the potential safety hazard caused by adding a non-stick coating to prevent uneven heating temperature distribution in the prior art to prevent sticking to the pot and the heat cannot be effectively used And the uneven temperature distribution of the uncoated inner pot can easily lead to the defect of the paste pot

Embodiment 1

[0037] Such as figure 2 As shown, a homogenizing pot containing liquid-absorbing cores of different apertures includes an inner pot and an outer pot with the same shape and different volumes. Both the inner pot and the outer pot are made of stainless steel, and the inner pot and the outer pot are made of stainless steel. The upper end of the outer pot is sealed and connected with a vacuum chamber between the two; a liquid-absorbing core and a liquid phase-change working medium are arranged in the vacuum chamber, and the liquid phase-change working medium is water; the liquid-absorbing core includes Two-layer (i.e. inner layer 61 and outer layer 62) laminated porous copper foam strips; the porous copper foam strips are rectangular strips, and the specific number can be 12. Distributed radially, the thickness of each layer is 1.5mm, and the porosity of each layer is 85%; the thickness of the inner layer 61, the middle layer 63 and the outer layer 62 are all 1mm, and the inner l...

Embodiment 2

[0039] Such as image 3 As shown, a homogenizing pot containing liquid-absorbing cores of different apertures includes an inner pot and an outer pot with the same shape and different volumes. Both the inner pot and the outer pot are made of stainless steel, and the inner pot and the outer pot are made of stainless steel. The upper end of the outer pot is sealed and connected with a vacuum chamber between the two; a liquid-absorbing core and a liquid phase-change working medium are arranged in the vacuum chamber, and the liquid phase-change working medium is water; the liquid-absorbing core includes 3-layer (i.e. inner layer 61, middle layer 63 and outer layer 62) laminated porous copper foam strips; The strips are radially distributed along the center of the pot, the thickness of each layer is 1mm, and the porosity of each layer is 85%; the thickness of the inner layer 61, the middle layer 63 and the outer layer 62 are all 1mm, and the inner layer is closely attached to the in...

Abstract

The invention relates to a uniform-temperature pot containing liquid absorbing cores of different hole diameters. The uniform-temperature pot comprises an inner-layer pot and an outer-layer pot, wherein the upper ends of the inner-layer pot and the outer-layer pot are in sealed connection, and a vacuum cavity is formed between the inner-layer pot and the outer-layer pot; the interior of the vacuumcavity is provided with at least one liquid absorbing core and a liquid phase-change working medium, and the liquid phase-change working medium can be heated to be changed from a liquid state into agas state; the average hole diameter of one side, near the inner-layer pot, of each liquid absorbing core is greater than the average hole diameter of one side, near the outer-layer pot, of each liquid absorbing core. The uniform-temperature pot has the advantages that because the average hole diameter of one side, near the inner-layer pot, of each liquid absorbing core is greater than the averagehole diameter of one side, near the outer-layer pot, of each liquid absorbing core, the suction pressure is increased, the upper part of the pot is quickly cooled, and the liquid phase-change workingmedium is quickly absorbed into each liquid absorbing core; the flowing drag of the liquid phase-change working medium is reduced, and the liquid phase-change working medium can flow down to a heat source location at the bottom part of the pot along each liquid absorbing core at quicker speed; the temperature difference at each part of the inner-layer pot is controlled within + / -5 DEG C, and foods in the pot can reach a good physical non-sticking effect in the use process.

Description

technical field [0001] The invention relates to a soaking pot with liquid-absorbing cores of different apertures, which belongs to the field of soaking pots. Background technique [0002] At present, the material of the inner tank of electric rice cooker or pressure cooker is generally aluminum alloy or aluminum alloy / stainless steel composite plate. They mainly realize the non-stick coating such as PTFE (Teflon) on the surface of the inner layer of aluminum to realize the surface in the cooking process. non-stick effect. However, these non-stick coatings have poor wear resistance and are relatively easy to fall off. After being absorbed by the human body, they may cause safety hazards to consumers' health. At present, companies such as Datong Electric Appliances of Taiwan, China, and Runtang Electric Appliances of Shenzhen have developed healthy uncoated inner pots heated by electric heating plates, which specifically achieve a certain physical non-stick effect by controll...
