Description

Technical Field

[0001] This utility model relates to a cookware, and more specifically, to an aluminum cookware with an anti-bulging bottom function when heated. Background Technology

[0002] Most existing aluminum cookware, designed for compatibility with induction cookers, microwave ovens, and ceramic cooktops, typically has a flat bottom. To prevent the cookware from becoming uneven or spinning on the cooktop, the bottom is usually designed to bulge slightly inwards. However, when heated, the difference in thermal expansion coefficients between the magnetic layer (magnetic sheet, thermal spray coating, cold spray coating, etc.) and the aluminum substrate causes the bottom to bulge inwards to varying degrees, increasing with temperature. Excessive bulging causes cooking oil to flow to the outside of the flat bottom, leading to burning and other unpleasant experiences. Severe bulging can also affect the magnetic conductivity of the induction cooker or even cause demagnetization, resulting in poor overall performance. Therefore, this invention proposes an aluminum cookware with an anti-bulging bottom function during heating. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an aluminum cookware with an anti-bulging bottom function when heated.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: The present utility model relates to an aluminum cookware with an anti-convex bottom function under heating conditions, comprising an aluminum die-cast flat-bottomed pot body with a slightly convex bottom, wherein the outer bottom of the aluminum die-cast flat-bottomed pot body is provided with a guide disk arranged in the center, the guide disk comprising a base layer integral with the aluminum die-cast flat-bottomed pot body, a magnetic conductive sheet pressed in the base layer, and a spray coating layer sprayed on the surface of the base layer, wherein a process groove is formed in the center of the guide disk, and a plurality of stress-relieving grooves extending radially are distributed around the guide disk, one end of the stress-relieving groove is connected to the process groove, and the other end is connected to the outside.

[0005] The present invention is further configured such that the included angle between two adjacent stress-relief grooves is equal.

[0006] The present invention is further configured such that the number of stress-relieving grooves is four, six, eight, or twelve.

[0007] In summary, the present invention has the following beneficial effects: The aluminum cookware with anti-bulging bottom function in the heating state involved in the present invention can improve the service life of the non-stick coating because the bottom of the pot does not run oil when heated, improve the magnetic conductivity on the induction cooker, shorten the heating time, reduce the energy consumption of the induction cooker, and has perfect overall functions and strong practicality.

[0009] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the patent claims of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0010] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0011] Example 1

[0012] See Figure 1 As shown, this embodiment relates to an aluminum cookware with an anti-convex bottom function under heating conditions, comprising an aluminum die-cast flat-bottomed pan body 1 with a slightly convex bottom. The outer bottom of the aluminum die-cast flat-bottomed pan body 1 is provided with a centrally arranged guide disk 2. The guide disk 2 includes a base layer integral with the aluminum die-cast flat-bottomed pan body 1, a magnetic conductive sheet pressed into the base layer, and a spray coating layer sprayed on the surface of the base layer. A process groove 3 is provided in the center of the guide disk 2. Several stress-relieving grooves 4 extending radially are distributed around the guide disk 2. One end of the stress-relieving groove 4 is connected to the process groove 3, and the other end is connected to the outside.

[0013] Furthermore, the included angle between two adjacent stress-relief grooves 4 is equal.

[0014] Furthermore, the number of stress-relieving grooves 4 is four, six, eight, or twelve.

[0015] In this embodiment, an aluminum substrate cookware shape (i.e., aluminum die-cast flat-bottomed pot body 1) is formed by using an aluminum die-casting machine. The outer bottom of the aluminum die-cast flat-bottomed pot body 1 is provided with concave grooves (i.e. stress-relieving grooves 4) arranged in a circular array with the center of the outer bottom as the center. These grooves run horizontally through the pot and cut the bottom surface of the cookware into several surfaces to release the expansion stress generated by the thermal spray coating or cold spray coating under heating.

[0016] The aluminum cookware of this utility model has an anti-bulging bottom function when heated. Because the bottom of the pot does not leak oil when heated, the service life of the non-stick coating can be improved, the magnetic conductivity on the induction cooker can be improved, the heating time can be shortened, the energy consumption of the induction cooker can be reduced, and the overall function is perfect and highly practical.
