Referring to fig. 2 and 3, in this embodiment, the inner pan 100 includes a pan body 1, an annular flanging ring 2 and a metal protection layer 3, an annular flanging 11 is formed at an upper port edge of the pan body 1, the pan body 1 includes an outer surface metal layer 12 and an inner surface metal layer 13, an annular mounting groove 21 is formed at an inner side of the annular flanging ring 2, the annular mounting groove 21 is matched with the annular flanging 11, wherein the outer surface metal layer 12 and/or the inner surface metal layer 13 is an easily-corroded metal layer capable of performing an original battery reaction with the annular flanging ring 2, and the annular flanging ring 2 is disposed to cover a part of an upper surface of the annular flanging 11 (such an arrangement can avoid a problem that salts and impurities generated by cooking are easily accumulated on the upper surface of a joint of the annular flanging ring 2 and the annular flanging 11), the metal protection layer 3 is at least arranged at a contact area where the annular edge covering ring 2 is contacted with the metal layer easy to corrode, so that the annular edge covering ring 2 is isolated from the metal layer easy to corrode, and the potential of the metal protection layer 3 is not higher than that of the metal layer easy to corrode.
The technical scheme provided in the utility model the surface of annular bordure 2 is equipped with metal protection layer 3, in order to incite somebody to action annular bordure 2 with pot body 1's the metal level of perishable looks separation, just metal protection layer 3's current potential is not higher than the current potential of the metal level of perishable, thereby protects the metal level of perishable is not corroded.
The outer surface metal layer 12 and/or the inner surface metal layer 13 of the pot body 1 are corrosion-prone metal layers, the total number of layers of the pot body 1 may not be specifically limited, for example, the number of layers of the pot body 1 may be one, at this time, the outer surface metal layer 12 and the inner surface metal layer 13 are the same layer, of course, the pot body 1 may also be two layers or more than two layers, for example, please refer to fig. 2, in this embodiment, the pot body 1 is formed by layering multiple metal layers, but no matter how many layers the pot body 1 includes, in the cooking process, the inner surface metal layer 13 of the pot body 1 is more likely to contact with electrolytes such as brine or steam, and the inner surface metal layer 13 is often corroded, so in this embodiment, the inner surface metal layer 13 is the corrosion-prone metal layer.
Therefore, in order to protect the inner surface metal layer 13, the metal protection layer 3 may be disposed in such a manner that the metal protection layer 3 is provided on at least the upper side wall of the annular mounting groove 21 so as to block the upper side wall of the annular mounting groove 21 from the inner surface metal layer 13; the metal protection layer 3 may also cover the entire inner wall surface of the annular mounting groove 21, so that the metal protection layer 3 can achieve a better protection effect on the metal layer easy to corrode and is easier to process and manufacture no matter whether the metal layer easy to corrode is the outer surface metal layer 12 or the inner surface metal layer 13; the metal protection layer 3 can also be covered on the whole surface of the annular edge covering ring 2, so that the production process is simplified, the method is suitable for large-scale batch production of products, and in addition, compared with the method that the metal protection layer 3 is locally arranged on the surface of the annular edge covering ring 2, the method can prevent the problem that a large amount of accumulated liquid on the annular flanging 11 is used as electrolyte in the cooking process, and the surface of the annular edge covering ring 2 without the metal protection layer 3 is connected with the metal layer easy to corrode, so that the metal layer easy to corrode is corroded. Of course, whether the inner surface metal layer 12 is the corrosion-prone metal layer, the outer surface metal layer 13 is the corrosion-prone metal layer, or both of them are the corrosion-prone metal layers, the metal protection layer 2 may cover the entire inner wall surface of the annular mounting groove 21, or the metal protection layer 3 covers the entire surface of the annular bezel 2, so as to protect the corrosion-prone metal layer.
Galvanic corrosion can occur between the corrosion-prone metal layer of the pot body 1 and the annular containment ring 2, generally because the two materials have different potentials, and the potential of the annular containment ring 2 is higher than that of the corrosion-prone metal layer, so that the corrosion-prone metal layer can be corroded. In order to protect the annular flanging 11 of the pot body 1 from being damaged by collision and to make the product overall beautiful, the annular edge covering ring 2 is generally made of stainless steel or titanium alloy. However, in order to improve the overall heat conductivity of the pot body 1 or facilitate the process, the pot body 1 generally includes an aluminum layer, and the aluminum layer has a low potential and is often corroded, so in this embodiment, the corrosion-prone metal layer is made of aluminum.
The metal protection layer 3 can protect the metal layer prone to corrosion from corrosion because the potential of the material of the metal protection layer 3 is not higher than that of the metal layer prone to corrosion, specifically, the material of the metal protection layer 3 is magnesium or aluminum, so that the potential of the metal protection layer 3 is equal to or closer to that of the metal layer prone to corrosion, galvanic corrosion is not formed between the metal layer and the metal layer, the metal layer prone to corrosion can be protected from corrosion, and the metal protection layer 3 is also not prone to corrosion.
The protection effect of the metal protection layer 3 on the metal layer prone to corrosion is related to the potential of the metal protection layer 3 and the thickness of the metal protection layer 3, the metal protection layer 3 is too thin, the protection effect is poor, and the metal protection layer is not easy to process (in this embodiment, the metal protection layer 3 is formed by performing processes such as vacuum plating, electroplating, thermal spraying or cold spraying on the surface of the annular edge covering ring 2, so that the process is simple, the metal protection layer is easy to machine and form, and is easy to wear away, specifically, in this embodiment, the thickness of the metal protection layer 3 is 0.3-2.0 μm, so that the metal protection layer 3 has a good protection effect, and simultaneously, the problem that the cost is increased due to the fact that the metal protection layer 3 is too thick is avoided, and the metal protection layer is easy to machine and manufacture, the performance-price ratio is high, and the method is suitable for large-scale batch production of products.
Because the potential of the metal protection layer 3 is lower than or equal to the potential of the metal layer easy to corrode of the pot body 1, the problem that the metal protection layer 3 is corroded or abraded can exist in long-term use, so that the protection effect on the metal layer easy to corrode can be influenced, in the embodiment, the surface of the metal protection layer 3 is coated with the insulation layer 4, the problem that galvanic corrosion occurs between the metal layer easy to corrode of the pot body 1 and the annular edge-covering ring 2 can be further prevented through the insulation effect of the insulation layer 4, the protection effect on the metal layer easy to corrode is good, in addition, the insulation layer 4 covers the metal protection layer 3, the protection effect on the metal protection layer 3 can also be realized, and the problem that the metal protection layer 3 is corroded or abraded can be prevented.
Specifically, in this embodiment, the insulating layer 4 is an acrylic resin coating, a polyurethane resin coating, or an epoxy polyester resin coating, so that the insulating layer 4 has a good insulating effect, does not generate substances harmful to a human body in a long-term use process, is easy to process and manufacture, and has a relatively low cost.
Through setting up insulating layer 4 protects metal protection layer 3, in order to avoid causing because of long-term the use insulating layer 4 is worn and torn, insulating layer 4's thickness should not be too thin, and too thin also is difficult to process (generally be in metal protection layer 3's surface is through electrophoresis or spraying in order to form insulating layer 4, so, the technology is comparatively simple, also easily machine-shaping), in this embodiment, insulating layer 4's thickness is 10 ~ 20 mu m, so sets up, insulating layer 4 not only is right metal protection layer 3 protective effect is better, also avoids simultaneously insulating layer 4 is too thick leads to the problem of cost-push to, and also easily manufacturing, the sexual valence is higher, is applicable to the large-scale batch production of product.
As described above, in this embodiment, the pot body 1 is formed by bonding a plurality of metal layers, specifically, the inner metal layer 13 is made of aluminum, and the inner layer of the pot body 1 is made of aluminum, so that not only the heat conductivity of the pot body 1 can be improved, but also the process treatment of the inner surface of the pot body 1 is facilitated.
Similarly, in this embodiment, the outer surface metal layer 12 is made of carbon steel or cast iron, and the outer layer of the pot body 1 is made of carbon steel or cast iron, so that the overall strength of the pot body 1 can be ensured, the problem of easy collision and damage can be avoided, the pot body 1 can be suitable for electromagnetic heating and electric heating, and the universality of the pot body 1 is improved.
Specifically, in this embodiment, the thickness of the outer surface layer metal layer 12 is 0.8-2.0 mm, so that the problem that the strength of the pot body 1 is affected by the too thin thickness of the outer surface layer metal layer 12 can be avoided, and meanwhile, the problem that the cost is wasted due to the too thick thickness of the outer surface layer metal layer 12 can also be avoided.
Because various functional coatings are generally applied to the inner side surface of the pot body 1, the inner side surface of the pot body 1 needs to be polished before the coating is formed on the inner side surface of the pot body 1, the inner surface metal layer 13 of the pot body 1 is not easy to be too thin, and specifically, in this embodiment, the thickness of the inner surface metal layer 13 is greater than or equal to 0.05 mm.
Further, the thickness of the inner surface metal layer 13 is 0.05-0.5 mm, so that the problem that the inner surface metal layer 13 is too thin and is easy to polish off can be avoided, and the problem that the cost is wasted due to the fact that the inner surface metal layer 13 is too thick is also avoided.
In order to meet various requirements of users on product performance, referring to fig. 2, a non-stick coating 5 may be coated on the inner surface metal layer 13 to prevent food from sticking to a pan, specifically, in this embodiment, the non-stick coating 5 is a fluororesin coating or a ceramic non-stick coating, and thus, the non-stick coating 5 has good performance and a stable structure, and no substances harmful to a human body are generated in a heating process. Similarly, an outer spray coating 6 such as an antirust coating or an abrasion resistant coating may be applied to the outer surface metal layer 12.
Further, in order to prevent the non-stick coating 5 from being peeled off from the edge, in this embodiment, the non-stick coating 5 is extended to the upper surface of the annular flange 11, so that the edge of the non-stick coating 5 is located in the annular mounting groove 21, and the non-stick coating 5 is not easily peeled off from the edge. Similarly, in order to prevent the outer sprayed layer 6 from peeling off from the edge, in the present embodiment, the outer sprayed layer 6 is provided to extend to the lower surface of the annular flange 11.
