In the cooking utensil provided by the application, the first layer 21 and the second layer 22 are inorganic porous material layers or self-lubricating material layers, the inorganic porous material layers have amorphous structures, the arrangement of atoms in a three-dimensional space is short-range ordered and long-range disordered, and the surface energy is small; and the diameter of the hole is micron-level, so that a large amount of edible oil can be adsorbed in the actual use process, and a layer of oil film is always kept on the surface. The self-lubricating material has a layered crystal structure, and the interlayer slippage is good, just like grease; in addition, the self-lubricating material layer has a special layered structure, a plurality of gaps are formed among the layered structures, the size of the gaps is in a micron level, a large amount of edible oil can be adsorbed in the actual use process, a layer of oil film is always kept on the surface, direct contact between food and the pot body 1 is avoided, the non-stick mechanism of the non-stick layer 2 is met, and therefore the probability that the food sticks to the pot is reduced.
The inorganic porous material has non-stick performance due to the characteristics of low surface energy and porous oil absorption, and the self-lubricating material has non-stick performance due to the characteristics of self-lubrication and porous oil absorption formed by the lamellar crystal, so that the non-stick layer has certain non-stick performance. The inorganic porous material and the self-lubricating material have stable crystals and high melting points, so that the inorganic porous material and the self-lubricating material have better thermal stability and high temperature resistance, and have stable structures and are not easy to change substances in the cooking process, so that the inorganic porous material and the self-lubricating material are not easy to age. Inorganic porous material and self-lubricating material's hardness is big, mechanical strength is big, even when using the shovel to carry out food culinary art, also be difficult for appearing the fish tail to cooking utensil's durability can be effectively improved, cooking utensil's life has been prolonged. The non-stick layer is an inorganic porous material layer or a self-lubricating material layer which is not easy to fall off, so that the non-stick coating adopted in the prior art is replaced, and the inorganic porous material and the self-lubricating material are both natural materials, are healthy and non-toxic, and can ensure the health of a user.
Further, the porosity of the first layer 21 is greater than or equal to the porosity of the second layer 22. The first layer 21 has a relatively large porosity, the first layer 21 having a relatively large porosity is formed on the pot body 1, and the second layer 22 having a relatively small porosity or an equal porosity is formed on the upper layer of the first layer 21. In the scheme, the pores enable the propagation of heat to develop from surface propagation to line propagation, so that the heat transfer area of the non-stick layer is reduced; the heat transfer medium in the pore is air with lower heat conductivity, so the relatively higher porosity can reduce the heat conduction speed of the first layer 21, the surface heat of the first layer 21 is uniformly distributed, the heat conduction of the non-stick layer 2 is more uniform, no crack is generated, the phenomenon of local overheating can be reduced when the novel cooking appliance is used for cooking, and the generation of oil smoke is prevented.
In a particular embodiment, the porosity of the first layer 21 ranges from 10% to 70%, and/or the porosity of the second layer 22 ranges from 0.5% to 30%. That is, where it is desired that the porosity of the first layer 21 be greater than the porosity of the second layer 22, in one embodiment, only the porosity of the first layer 21 need be in the range of 10% to 70%; in another embodiment, it is only necessary that the porosity of the second layer 22 be in the range of 0.5% to 30%; in a more preferred embodiment, the porosity of the first layer 21 ranges from 10% to 70% and the porosity of the second layer 22 ranges from 0.5% to 30%. In any of the above embodiments, the nonstick property of the nonstick layer 2 can be made better as long as the porosity is within the above range.
Illustratively, the first layer 21 has a porosity of 10%, 30%, 50%, and 70%, and the first layer 21 performs best when it has this porosity.
Also illustratively, the second layer 22 has a porosity of 0.5%, 10%, 20%, and 30%, and the second layer 22 performs best when it has this porosity.
In a particular embodiment, the porosity of the first layer 21, located at the bottom of the pan body 1 up to one third of the height of the wall, is greater than the porosity of the first layer 21, located at one third of the height of the wall of the pan body 1 up to the opening of the pan body 1.
When food is stir-fried in the region corresponding to the height from the bottom of the pot body 1 of the cooking appliance to one third of the wall part, the relatively high porosity can reduce the heat transfer area of the non-stick layer 2, and air is used as a heat transfer medium and has low heat conductivity, so that the heat conduction efficiency can be reduced, the heat distribution in the region is uniform during stir-frying, and the generation of oil smoke caused by local overheating is prevented. The region corresponding to the opening from the one-third height of the wall part of the pot body 1 to the pot body 1 is heated less and used less, the lower porosity does not cause adverse effect on the non-adhesiveness of the region, and the uniform heat conduction of all the regions in the pot body 1 is favorably realized.
Specifically, the porosity of the first layer 21 at the height of one third of the wall part from the bottom of the pot body 1 ranges from 40% to 70%; and/or the porosity of the first layer 21 from one third of the height of the wall of the pan body 1 to the opening of the pan body 1 is in the range of 10% -30%.
That is, in the case where it is satisfied that the porosity of the first layer 21 at the height of one third of the wall from the bottom of the pan body 1 is greater than the porosity at the height of one third of the wall of the pan body 1 to the spout of the pan body 1, in one embodiment, it is only necessary that the porosity of the first layer 21 at the height of one third of the wall from the bottom of the pan body 1 is in the range of 40% -70%; in another embodiment, the porosity range from the one third height of the wall part of the pot body 1 to the pot opening of the pot body 1 is only 10-30%; in a more preferred embodiment, the porosity of the first layer 21 at the bottom of the pan body 1 to one third of the height of the wall is in the range of 40% -70%, and the porosity at one third of the height of the wall of the pan body 1 to the mouth of the pan body 1 is in the range of 10% -30%. In either of the above embodiments, the non-stick property of the first layer 21 can be made better as long as the porosity is within the above range.
Illustratively, the porosity of the first layer 21, at the level of the bottom to one third of the wall of the pan 1, is 40%, 50%, 60% and 70%, the areas having this porosity being the best one for the performance.
Also, the porosity of the first layer 21, which is exemplarily located at one third of the height of the wall of the pan 1 to the opening of the pan 1, is 10%, 20%, 25% and 30%, which regions perform best when having this porosity.

When food is stir-fried in an area corresponding to the height from the bottom of the pot body 1 of the cooking appliance to one third of the wall part, the relatively high porosity can reduce the heat transfer area of the non-stick layer 2, and air serving as a heat transfer medium has low heat conductivity, so that the heat conduction efficiency can be reduced, the heat distribution on the inner surface of the pot in the area for stir-frying the food is uniform, and the generation of oil smoke is prevented. The region corresponding to the opening from the one-third height of the wall part of the pot body 1 to the pot body 1 is heated less and used less, the lower porosity does not cause adverse effect on the non-adhesiveness of the region, and the uniform heat conduction of all the regions in the pot body 1 is favorably realized.
Specifically, the porosity of the second layer 22 at the height of one third of the wall from the bottom of the pot body 1 is in the range of 10% -30%; and/or the porosity of the second layer 22 from one third of the height of the wall of the pot 1 to the opening of the pot 1 is in the range of 0.5-8%.
That is, in the case where it is satisfied that the porosity of the second layer 22 at the height of one third of the wall from the bottom of the pot 1 is greater than the porosity at the height of one third of the wall of the pot 1 to the spout of the pot 1, in one embodiment, it is only necessary that the porosity of the second layer 22 at the height of one third of the wall from the bottom of the pot 1 is in the range of 10% -30%; in another embodiment, the porosity range from the one third height of the wall part of the pot body 1 to the pot opening of the pot body 1 is only 0.5-8%; in a more preferred embodiment, the porosity of the second layer 22 at the bottom of the pan body 1 to one third of the height of the wall is in the range of 10% -30%, and the porosity at one third of the height of the wall of the pan body 1 to the mouth of the pan body 1 is in the range of 0.5% -8%. In either of the above embodiments, the non-stick property of the second layer 22 can be made better as long as the porosity is within the above range.
Illustratively, the porosity of the second layer 22 is 10%, 15%, 25% and 30% at the bottom to one third of the height of the wall of the pan 1. The above-mentioned region has the best performance when it has this porosity.
Likewise, the porosity of the second layer 22, for example at the level of one third of the wall of the pan 1 to the opening of the pan 1, is 0.5%, 3%, 5% and 8%. The above-mentioned region has the best performance when it has this porosity.
In particular, the non-stick layer 2 has a thickness in the range of 30 μm to 300 μm. Within the thickness range, the non-stick layer 2 can be prevented from falling off, exposing the bottom and the like due to abrasion in the long-term use process because of being too thin, the durable non-stick service life is realized, the uniform heat transfer on the surface in the pot can be ensured, and the problems of loose structure, increased pores, reduced coating hardness or adhesive force and the like of the outer surface of the non-stick layer 2 due to too thick non-stick layer 2 can be avoided. Illustratively, the thickness of the non-stick layer 2 may range from 30 μm, 60 μm, 120 μm, 200 μm, 300 μm, and so on. The non-stick layer 2 has the best performance when it has the above thickness.
In a particular embodiment, the thickness of the non-stick layer 2 from the bottom to one third of the height of the wall of the pan body 1 is greater than the thickness from one third of the height of the wall of the pan body 1 to the mouth of the pan body 1.
Whether the electromagnetic oven or the open fire is used for heating, the part from the bottom of the pot body 1 to one third of the height of the wall part is a main heated area, the temperature of the part is increased quickly, but the temperature of the bottom of the pot can be increased slowly by the thick non-stick layer of the area; the region from the bottom of the pot body 1 to one third of the height of the wall part is far away from the heat source, and the temperature rise speed can be accelerated due to the thin region, so that the temperature rise speeds of the two regions can be close to each other, the heat transfer on the inner surface of the pot is uniform, and the oil smoke problem caused by overhigh local temperature is avoided; and the problem of non-stick layer damage caused by long-term local high temperature is also avoided. Moreover, when food is fried on the pan bottom, the non-stick layer at the pan bottom is easily scratched and abraded by the shovel or the hard food, and the thicker non-stick layer can effectively reduce the scratch and abrasion caused by the shovel or the hard food, so that the service life of the cooking utensil is prolonged.
Specifically, the thickness of the non-stick layer 2 at the position from the bottom of the pan body 1 to one third of the height of the wall part is in the range of 80-300 μm; and/or the thickness range from one third of the height of the wall part of the pot body 1 to the pot opening of the pot body 1 is 30-180 mu m.
That is, in the case where it is satisfied that the thickness of the non-stick layer 2 at the height of the bottom to one third of the wall portion of the pot body 1 is greater than the thickness of the non-stick layer 2 at the height of the one third of the wall portion of the pot body 1 to the spout of the pot body 1, in one embodiment, it is only necessary that the thickness of the non-stick layer 2 at the height of the bottom to one third of the wall portion of the pot body 1 is in the range of 80-300 μm; in another embodiment, the thickness range from one third of the height of the wall part of the pot body 1 to the pot opening of the pot body 1 is only 30-180 μm; in a more preferred embodiment, the non-stick layer 2 has a thickness ranging from 80 to 300 μm at the level of the bottom of the pan body 1 to one third of the height of the wall, and a thickness ranging from 30 to 180 μm at the level of one third of the height of the wall of the pan body 1 to the mouth of said pan body 1. In any of the above embodiments, the non-stick property of the non-stick layer 2 can be made good as long as the thickness falls within the above range.
For example, the thickness of the non-stick layer 2 in this area may be 80 μm, 150 μm, 200 μm, 300 μm, etc., at which the performance of the non-stick layer 2 is optimal.
Also, for example, the thickness of the non-stick layer 2 in this area may be 30 μm, 60 μm, 120 μm, 180 μm, etc., at which the performance of the non-stick layer 2 is optimal.
Further, the particle size range of the non-stick layer 2 is 300-2000 mesh. In the above scheme, the cost is high when the particle size is larger than 2000 meshes, and the structure on the surface of the powder is damaged when the particle size is too small, so that the non-stick effect of the non-stick layer 2 is affected. The powder material with the particle size less than 300 meshes has difficult preparation process and low output efficiency. For example, the non-stick layer 2 may have a particle size of 300 mesh, 500 mesh, 1000 mesh, 1500 mesh, 2000 mesh, etc. The non-stick layer 2 has the best performance with this particle size.
Specifically, the first layer 21 has a particle size range of 300-500 mesh; and/or the second layer 22 has a particle size in the range of 500-2000 mesh.
That is, where the granularity of the first layer 21 is greater than the granularity of the second layer 22, in one embodiment, the granularity of the first layer 21 is only required to be 300-500 mesh; in another embodiment, the second layer 22 only needs to have a particle size of 500-2000 mesh; in a more preferred embodiment, the first layer 21 has a particle size of 300-500 mesh and the second layer 22 has a particle size of 500-2000 mesh. In any of the above-mentioned embodiments, the non-stick property of the non-stick layer 2 can be made good as long as the particle size is within the above-mentioned range.
Illustratively, the first layer 21 may have a particle size of 300 mesh, 400 mesh, 480 mesh, 500 mesh, and the like. The first layer 21 has the best performance with this particle size.
Also, for example, the second layer 22 may have a particle size of 500 mesh, 1000 mesh, 1500 mesh, 2000 mesh, and so on. The second layer 22 performs best with this particle size.
Specifically, when the non-stick layer 2 is an inorganic porous material layer, the inorganic porous material layer is a diatomite layer, a bentonite layer or a zeolite layer; the self-lubricating material layer is a graphite layer, a graphite fluoride layer or a molybdenum disulfide layer. Wherein, the first layer 21 and the second layer 22 are both inorganic porous material layers or self-lubricating material layers, or one of the first layer 21 and the second layer 22 is an inorganic porous material layer, and the other is a self-lubricating material layer. The diatomite, bentonite or zeolite is a natural inorganic porous material, and has the advantages of convenient acquisition of raw materials and low manufacturing cost. The graphite layer, the graphite fluoride layer and the molybdenum disulfide layer are convenient to obtain raw materials and low in manufacturing cost.
The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
