As shown in fig. 1 and fig. 2, the present embodiment provides a cooking appliance, which includes a pot body 1 and a pot cover, the pot cover covers an opening of the pot body 1, and the cooking appliance may be a wok, a frying pan, or other cooking appliances for cooking, and is not limited in particular. Wherein, in order to avoid the food material of cooking in the pot body 1 to easily glue the bottom of a boiler after heating, the inner wall of the pot body 1 is provided with the non-stick layer, thereby forming the non-stick pot, and the non-stick pot in use, frying the stir-fry in process, the slice can be repeated and contact with the non-stick layer, easily lead to droing of the non-stick layer, thereby influence the effect of the non-stick pot. Aiming at the situation, the inner wall of the pan body 1 is etched, and the non-stick layer is coated on the concave part of the etched lines, so that the contact collision between the slice and the non-stick layer is avoided, and the etched line pan with the non-stick effect is formed.

The pan body 1 of the existing non-stick pan or the existing etched-pattern pan is generally formed by adopting a three-layer composite plate, the weight of the pan body 1 is larger, and in order to reduce the weight of the pan body 1, the application provides a plate for a cooking utensil, which comprises a composite plate formed by a stainless steel layer 111 and an aluminum layer 112, wherein the surface of the stainless steel layer 111 is provided with an etched concave-convex layer 115; the thickness ratio between the stainless steel layer 111 and the aluminum layer 112 is 1: 4-1: 7. in order to avoid at tensile in-process, the fashioned mould of debugging or change tensile power that the technical staff need relapse, guarantee the shape of final fashioned pot body 1, so to the thickness ratio of stainless steel layer 111 and aluminium lamination 112 in the composite board who chooses for use formation pot body 1, with the difference of the proportion through each layer thickness in the panel, make the restriction power between balanced stainless steel layer 111 and the aluminium lamination 112 of tensile in-process, thereby reduce the excessive deformation of etching unsmooth layer 115 position, guarantee the better shaping effect of pot body 1. And to the setting of the thickness ratio of stainless steel layer 111 and aluminium layer 112 in the two-layer composite board that sets up, according to the difference of the shape of the pot body 1 that will shape, for example the frying pan that the lateral wall 13 slope is comparatively gentle, the frying pan that lateral wall 13 is the straight wall, the thickness ratio between stainless steel layer 111 and the aluminium layer 112 is different, the thickness ratio between stainless steel layer 111 and the aluminium layer 112 can be 1: 4.5-1: 6.5 or 1: 5-1: 6 or 1: 4-1: 4.5. the specific thickness ratio can be adjusted adaptively within the range of the thickness ratio according to the different shapes of the stretched pot body 1 so as to ensure the stability of the pot body stretching forming and avoid the deformation of etched grains.

As a specific embodiment of the present application, as shown in fig. 1 and fig. 2, the cooking utensil comprises a pot body 1, the base material of the pot body 1 is formed by stretching the two-layer composite plate, the pot body 1 has an inner surface 11, the stainless steel layer 111 is the inner surface 11 of the pot body 1 contacting with food, and the outer surface facing away from the inner surface 11 is the outer surface of the pot body 1 and is an aluminum layer 112. In order to realize the stretch forming of the pot body 1 through two-layer composite board, and correspond the concrete shape of the pot body 1 of required shaping, select suitable thickness ratio in the thickness ratio range of stainless steel layer 111 and aluminium lamination 112 in panel to ensure that in the stretch forming process, all can guarantee better shaping effect, improve fashioned stability.

Specifically, the pot body 1 is provided with a bottom 12 and a side wall 13, and a preset angle is formed between the bottom 12 and the side wall 13; the variation of the preset angle has an effect on the thickness ratio between the stainless steel layer 111 and the aluminum layer 112 in the selected plate material. Wherein, to different pot types, the shape of bottom 12 and lateral wall 13, predetermine the contained angle homoenergetic and can influence horizontal power or vertical power when tensile to tensile resistance when the influence is tensile. Therefore, by means of the shape and preset angle of different side walls 13, two layers of the stainless steel layer 111 and the aluminum layer 112 with different thickness ratios can be selected correspondingly, so that the stretching stability is improved, and the forming precision is ensured.

More specifically, the optional range of the thickness ratio between the stainless steel layer 111 and the aluminum layer 112 is adjusted correspondingly by designing the pan body 1 to be located at different preset angles between the bottom 12 and the side wall 13 of the inner surface 11, so that the thickness ratio between the stainless steel layer 111 and the aluminum layer 112 decreases as the preset angle increases. With increasing preset angle, the smaller the tensile deformation force, the smaller the thickness ratio can be selected, as follows:

as shown in fig. 1 and 4, when the bottom 12 and the side wall 13 are perpendicular to each other, the preset included angle is a pan shape with 90 degrees; as shown in fig. 3, a pan shape with an included angle larger than 90 degrees is preset;

to different angle of predetermineeing, its thickness ratio can do corresponding adjustment, and when predetermineeing the angle and being equal to 90 degrees, and lateral wall 13 was parallel with the axis of the pot body 1 promptly, before the shaping, the thickness ratio between stainless steel layer 111 and aluminium lamination 112 in the two-layer panel of chooseing for use was 1: 4-1: 4.5. since the side wall 13 is perpendicular to the bottom 12, the side wall 13 and the bottom 12 are both straight walls and have rounded corners therebetween during stretch forming, and the straight portion of the side wall 13 and the flat portion of the bottom 12 are stretched with a small tension force to facilitate feeding of the rounded portion, so that, in order to avoid the easy deformation of the portions, the thickness ratio between the stainless steel layer 111 and the aluminum layer 112 of the plate material is set to 1: 4-1: 4.5, so that when the part of the concave-convex layer 115 etched in the stretching process is not easy to generate an uneven structure, the material passing of the fillet part can be avoided.

When the preset angle is greater than 90 degrees, the thickness ratio between the stainless steel layer 111 and the aluminum layer 112 is in the range of 1: 4.5-1: 6.5. as the slope of the side wall 13 increases, the sheet material of the side wall 13 is subjected to more lateral force during stretching, so that the sheet material is subjected to more force and is easily deformed. Therefore, in order to avoid the portion being easily deformed, the thickness ratio between the stainless steel layer 111 and the aluminum layer 112 of the plate material is set to 1: 4.5-1: 6.5, so that when the requirement that the part of the concave-convex layer 115 etched in the stretching process is not easy to generate a concave-convex structure, the phenomenon that the lateral wall is subjected to large transverse force to cause material discharge can be avoided.

It should be emphasized that, in general, the nonstick pan with the texture is generally a wok, a frying pan, etc., and therefore, the above description mainly refers to the pan body 1 with the preset angle greater than or equal to 90 degrees, but the pan body 1 with the preset angle smaller than 90 degrees is not excluded, and the same is also applicable to the pan body 1, and is not specifically described here.

In addition, since the side wall 13 may be a straight wall or an arc wall, the design of the thickness ratio of the stainless steel layer 111 and the aluminum layer 112 may be affected by the shape of the side wall 13. Specifically, when the preset angle is equal to 90 degrees, the side wall 13 is an arc-shaped wall, in the pot shape, the rounded part of the part which is easy to be fed between the side wall 13 and the bottom 12 and the vertical force applied to the arc-shaped side wall 13 are relatively large, and for this situation, the thickness ratio between the stainless steel layer 111 and the aluminum layer 112 before forming is set to be 1: 5-1: 6. and when predetermineeing the angle and being greater than 90 degrees, lateral wall 13 is the arc wall, in this kind of pot type, because the arc wall can receive vertical power, so the thickness ratio setting between stainless steel layer 111 and aluminium lamination 112 before will shaping is 1: 5-1: 6.5.

the present application further provides a specific embodiment, as shown in fig. 2, for the setting of the etching concave-convex layer 115, in order to ensure that the etching concave-convex layer has good stability and is not easy to deform when being stretched, the etching concave-convex layer 115 includes a plurality of protrusions 115a, and the height of the protrusions 115a protruding from the stainless steel layer 111 is 0.08mm to 0.13 mm. Namely, the stainless steel layer 111 on the plate is processed by etching to form the etching concave-convex layer 115, and the plurality of protrusions 115a are etched on the plate, so that the processing is facilitated, and the processing difficulty is reduced. In the range, the protrusions 115a protruding from the stainless steel layer 111 are not deformed or damaged due to too low strength of the shape of the etched concave-convex layer 115 during the stretch forming process.

Moreover, in order to realize the non-stick effect of the pan body 1 and avoid the use of the slice to damage the non-stick layer, the non-stick layer is positioned in the groove 115b formed between every two adjacent protrusions 115 a. Specifically, an anti-sticking layer is coated on the inner surface of the pot body 1, and then the part of the protrusion 115a is polished smooth to expose the stainless steel material, so that the part of the groove 115b is attached with the sprayed anti-sticking layer, and the optimal film thickness of the anti-sticking layer is 30-45 microns.

Optionally, in order to enable the pot body 1 to be used for an induction cooker, the pot body 1 further comprises a magnetic conduction layer 113 and an anticorrosive layer 114; the magnetic conductive layer 113 may be a plate layer made of a magnetic conductive material; or a sprayed layer formed by spraying the magnetic conductive material. Specifically, magnetic conduction layer 113 is an iron layer, magnetic conduction layer 113 is arranged on the outer surface of pot body 1, magnetic conduction layer 113 at least covers bottom 12, and anticorrosive layer 114 is sprayed on the outer wall of magnetic conduction layer 113 in a melting manner. Wherein, the thickness of the magnetic conduction layer 113 is 0.3-0.5 mm, and the thickness of the spray anticorrosion layer 114 is 0.1-0.2 mm.

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.
