Abstract
Description
Technical Field
[0001] This utility model relates to the field of cookware technology, and in particular to an inner pot structure for cooking utensils. Background Technology
[0002] Non-stick coatings are created by treating the bottom surface of the pan's interior to form a non-stick layer. This makes the surface less prone to food and grease adhesion and easier to clean. For example, a Teflon coating can be applied to the inner surface of the pan, utilizing the properties of Teflon to achieve its non-stick and easy-to-clean properties. However, the non-stick layer is easily scratched by knives, spatulas, and other metal objects, affecting its non-stick performance. Utility Model Content
[0003] To solve the above problems, this technical solution provides an inner pot structure for cooking utensils.
[0004] To achieve the above objectives, the technical solution is as follows:
[0005] An inner pot structure for a cooking appliance, comprising
[0006] The non-stick pan body comprises, in sequence, a magnetically conductive polished stainless steel layer, a steel-gold energy-storing substrate layer, and a medical-grade stainless steel layer.
[0007] The non-stick pan body has an inner cavity, and the medical stainless steel layer is located on the inner surface of the non-stick pan body;
[0008] The medical stainless steel layer is provided with a plurality of patterned protrusions that protrude toward the inner cavity, and the plurality of patterned protrusions form a mesh groove that is relatively recessed and interconnected with each other.
[0009] The inner pot structure for a cooking appliance as described above, wherein the medical-grade stainless steel layer is plated with a titanium layer.
[0010] As described above, the inner pot structure for a cooking utensil has an elliptical patterned protrusion that extends outward toward both ends of the short axis to form a pointed tip. The patterned protrusion includes elliptical sides located at both ends of the long axis, and transition sides extending from the pointed tip toward the elliptical sides and engaging with each other.
[0011] As described above, the inner pot structure for a cooking utensil includes a pot rim, a pot body, and a pot bottom connected in sequence, with a plurality of patterned protrusions arranged on the pot bottom to form an anti-stick portion.
[0012] In the cooking utensil inner pot structure described above, the non-stick part is laid at a height H of 20mm.
[0013] As described above, in the inner pot structure of a cooking utensil, the bottom of the pot gradually bulges towards the inner cavity from the bottom to the center to form an inner convex portion.
[0014] In the cooking utensil inner pot structure described above, the radius R1 of the inner convex portion is 300±20mm.
[0015] As described above, the inner pot structure of a cooking utensil has a bottom that gradually narrows with an arc radius R2 of 80±10mm.
[0016] As described above, in the inner pot structure of a cooking utensil, a plurality of the patterned protrusions are distributed in a mesh pattern.
[0017] In the cooking utensil inner pot structure described above, the width of the mesh groove is A, and the width of the patterned protrusion along its long axis is B, satisfying B>A.
[0018] The beneficial effects of this application are:
[0019] This invention provides an inner pot structure for a cooking utensil. By utilizing raised, textured bumps to support food, it reduces the contact area between food and the non-stick pan, making it less likely for food to adhere and improving the non-stick effect. At the same time, the textured grooves guide liquids (such as water or oil) to flow into the grooves, forming a liquid film isolation layer (such as steam or oil film), reducing direct contact between food and the pan surface.

The pan body is cylindrical.
[0033] Furthermore, as a preferred embodiment of this solution and not a limitation, the laying height H of the anti-sticking part 19 is 20mm.
[0034] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the bottom of the pot 18 gradually protrudes towards the inner cavity 14 from the bottom to the center to form an inner protrusion 10.
[0035] Furthermore, as a preferred embodiment of this solution and not a limitation, the radius R1 of the inner protrusion 10 is 300±20mm.
[0036] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the bottom of the pot 18 gradually narrows with an arc of radius R2 of 80±10mm.
