The first convex part is provided with the hardening part at the top wall exposed outside, so that the surface hardness of the top wall of the first convex part can be improved, the surface hardness of the cookware is greatly enhanced, tools such as a slice and a soup ladle are prevented from scratching the surface of the cookware, and the service life of the cookware is prolonged; on the other hand, the stiffened part can isolate the pan base body and the air, avoids the pan base body to turn yellow and change color in the heating process, helps to maintain the appearance of the pan, and improves the use performance of the pan.

It is to be understood that the first protrusion may have a stiffening portion only at the side wall, may have a stiffening portion only at the top wall, and may have a stiffening portion at both the side wall and the top wall.

In one possible design, the inner wall surface of the pot base body is provided with alternately distributed base convex parts and base concave parts, and a part of each first convex part is formed by one base convex part; the hardening part comprises a hardening layer which continuously covers the area of the pot base body corresponding to the target area.

In this design, one arrangement of the first convex and concave portions is specifically defined. The pot base body is provided with the base body convex part and the base body concave part, and the hardening part is specifically set to be the hardening layer, so that the hardening layer can directly cover the area of the pot base body corresponding to the target area. On one hand, from the aspect of a processing technology, a hardening layer can be continuously covered in an area of the pot base body corresponding to a target area, a non-stick layer is arranged on the surface of the continuous hardening layer, and the non-stick layer on the top of the first convex part is removed in the following ways of mechanical grinding, polishing and the like, so that the processing of the hardening part is simplified, and the processing efficiency is improved; on the other hand, the hardening layer can simultaneously play a reinforcing role in the concave part, even if the non-stick layer falls off a small amount to cause the corresponding concave part to be exposed, the damage of tools such as a slice and a soup ladle to the exposed concave part can be reduced, the damage can be prevented in time, and the damage is prevented from further expanding to other areas.

In one possible design, the inner wall surface of the pot base body is provided with alternately distributed base convex parts and base concave parts, and a part of each first convex part is formed by one base convex part; the stiffening part comprises a stiffening layer, and the stiffening layer covers the inner wall of the concave part of the substrate.

In this design, another arrangement of the first protrusions and recesses is specifically defined. This solution differs from the former arrangement in that the hardbanding covers only the inner walls of the base recess, including the inner bottom wall and the inner side walls of the base recess. Since the convex base portions and the concave base portions are alternately arranged, the inner side walls of the concave base portions also constitute the side walls of the convex base portions, and in terms of the convex base portions, it is equivalent to covering only the side walls of the convex base portions with the hard coating and not covering the top walls of the convex base portions with the hard coating. On the one hand, the design scheme of the cookware can be enriched, and the flexibility of product design is improved. On the other hand, from the aspect of the processing technology, in the process of removing the non-stick layer through mechanical grinding, polishing and the like, the removal thickness can be increased, and then the hardened layer on the top of the convex part of the base body is also removed, so that the hardened layer does not cover the convex part of the base body any more. Because the thickness of the non-stick layer is thin, the requirement on the processing precision is high when only the non-stick layer is removed, and the processing precision can be reduced by removing the hardened layer at the top of the convex part of the base body, so that the processing difficulty is reduced, and the processing efficiency is improved.

That is, when the stiffening portion is a stiffening layer, the first convex portion may have the stiffening layer at both the side wall and the top wall, or may have the stiffening layer only at the side wall.

In one possible design, the pan base comprises one or a combination of the following: an iron pan base body, a low-carbon steel pan base body and a stainless steel pan base body.

In the design, the pan base body may specifically include one or a combination of an iron pan base body, a low carbon steel pan base body, and a stainless steel pan base body. Wherein, the iron pan base body has the advantages of thin pan body and fast heat conduction; the low-carbon steel has good cold forming performance due to good plasticity and toughness, and can be processed into various pan body shapes; the stainless steel pot substrate has certain tolerance to acid and alkali, and is suitable for special cooking environment. Different cooking requirements can be met by selecting different pot bases.

In one possible design, the hardbanding is a rust resistant hardbanding.

In this design, specifically limited to add the hard coat and possess rust-resistant function simultaneously, add the hard coat promptly for rust-resistant to can promote the rust-resistant performance of pan when increasing the pan hardness, help prolonging the life of pan.

In one possible design, the hardbanding comprises one or a combination of: nitriding layer, metal layer.

In this design, the hardbanding may specifically include one or a combination of a nitrided layer and a metal plating layer. Specifically, for an iron pan base body or a low-carbon steel pan base body, a nitriding layer can be arranged through a nitriding process, the surface hardness of the nitriding layer can reach more than HRC64 and is far higher than HRC40 of stainless steel materials, and therefore scraping of the stainless steel slice can be effectively supported. In addition, the nitriding layer has certain non-stick property, therefore when the roof of first convex part has the nitriding layer, although the top of first convex part does not set up non-stick layer, the nitriding layer here also can play certain antiseized effect, helps promoting the holistic non-stick property of pan. For stainless steel pot substrates, a metal layer may be provided by a surface coating process, such as hard titanium coating, which may also achieve a hardness above HRC 64.

In one possible design, the thickness of the non-stick layer is less than the depth of the recess.

In this design, through the thickness that makes the non-stick layer that sets up in the concave part be less than the degree of depth of concave part, can make the surface of non-stick layer be less than the top surface of convex part to further reduce the friction of instruments such as slice, soup ladle and non-stick layer in the use, fully reduce the wearing and tearing of instrument to the non-stick layer, further promoted the anti-sticking performance of pan, and prolonged the life of non-stick layer.

In one possible design, the target area includes at least a portion of an inner bottom wall of the pan body.

In this design, the target area is specifically defined to include the entire inner bottom wall or a portion of the inner bottom wall of the pan body. Because in the pan use, instruments such as slice, soup ladle mainly contact with the interior diapire of pot body mutually, through set up the concave part on the interior diapire at pot body, can focus on strengthening this regional antiseized performance, both can satisfy basic antiseized demand, can rationally reduce the processingquantity again, help promoting machining efficiency, reduce material consumption, reduce the processing cost. Further, since the central region of the inner bottom wall is in contact with a spatula, soup ladle or the like, the central region of the inner bottom wall may be specifically included when the target region includes a portion of the inner bottom wall of the pan body. It can be understood that the target area can further comprise at least one part of the inner side wall of the pot body, so as to comprehensively improve the anti-sticking performance of the pot.

In one possible design, there are at least two of all the recesses that communicate with each other.

In this design, through making two at least concave parts communicate each other, the non-stick layer that sets up in the concave part also can communicate thereupon to enlarge the continuous distribution area of non-stick layer, and the concave part of intercommunication is more, and the continuous distribution area of non-stick layer is big more, can strengthen the adhesive force of non-stick layer, avoids the non-stick layer part to drop, has promoted the anti-sticking performance of pan, has prolonged the life of non-stick layer.

In one possible design, the outer contour shape of the recess includes one or a combination of the following: polygonal, circular, and irregular.

In this design, the outer contour shape of the concave portion may be a polygon, such as a triangle, a quadrangle, a hexagon, a circle, or a special shape. The non-stick layer can comprise a pattern to simplify the structure and facilitate processing, and can also be composed of various patterns to realize rich and flexible non-stick layer arrangement scheme, thereby reducing the falling possibility of the non-stick layer. It will be appreciated that, in order to define the outer contour shape of the recess, when two adjacent recesses are in communication, the channel connecting the two recesses may be provided with an anti-adhesive layer, but not received within the outer contour of the corresponding recess.

In one possible design, the outer contour shape of the first convex part comprises one or a combination of the following: polygonal, circular, and irregular.

In this design, the outer contour shape of the first convex portion may be a polygon, such as a triangle, a quadrangle, a hexagon, a circle, or a special shape. Can include a figure to simplify the structure, be convenient for process, also can constitute by multiple figure, the combination of different shapes can make the connection between each first convex part inseparabler, so that make the interval between two adjacent first convex parts more reasonable, can bear the friction of instruments such as slice, soup ladle better, the non-stick layer in the protection concave part.

In one possible design, the target area of the pan body is further provided with a second convex part, and the second convex part is positioned on the bottom wall of the at least one concave part; at least a part of each second convex portion is constituted by a stiffened portion.

In this design, the bottom wall of at least one recess is further provided with a second protrusion, at least a part of which is also formed by a hardened portion, as with the first protrusion, and both of which serve as protrusions that can serve the same purpose of reducing friction between a tool such as a spatula or soup ladle and the non-stick layer. Set up the second convex part through the diapire at the concave part, can cooperate with first convex part for interval between each concave part is more reasonable, and can suitably enlarge the surface area of single concave part, thereby enlarge the continuous distribution area of non-stick layer, can strengthen the adhesive force of non-stick layer, avoid the non-stick layer part to drop, promoted the anti-sticking performance of pan, prolonged the life of non-stick layer.

In one possible design, the width of each base projection is greater than or equal to 0.2mm and less than or equal to 1.5 mm.

In this design, the width of each base projection is specifically limited to a range of 0.2mm to 1.5 mm. The lower limit value can ensure that the first convex part formed by the convex part of the base body has enough strength, and reduce the damage to the first convex part when tools such as a turner scrape a pot. Since the surface of the first projection is free from the non-stick layer, the anti-sticking performance of the cookware can be reduced, and the upper limit value can limit the area of the first projection formed by the substrate projection, thereby being beneficial to ensuring the anti-sticking performance of the cookware.

In a possible design, the distance between two adjacent base protrusions is greater than or equal to 0.2mm and less than or equal to 4 mm.

In the design, the range of the distance between two adjacent base body convex parts is specifically limited to be 0.2mm to 4 mm. The lower limit value ensures that the protrusions of the base body have a sufficient distance therebetween to ensure that the non-stick layer can be effectively adhered to the surface of the recess when the non-stick layer is provided. This upper limit ensures effective support of the spatula or like implement and helps to reduce damage to the non-stick layer in the recess by the spatula or like implement during use.

In one possible design, the depth of each substrate recess is greater than or equal to 0.2mm and less than or equal to 0.8 mm.

In this design, it is specifically defined that the depth d2 of each base recess is in the range of 0.2mm to 0.8 mm. The lower limit ensures that the corresponding recess is deep enough to make the surface of the non-stick layer lower than the top surface of the projection, reducing the wear of the non-stick layer by the tools such as a slice. The upper limit value can reduce the processing difficulty of the concave part of the substrate, shorten the processing time, improve the processing efficiency and contribute to reducing the processing cost.

In one possible design, the ratio of the depth of each base recess to the thickness of the pan base is equal to or less than 1/2.

In the design, the depth of the concave part of the base body is limited to be less than half of the thickness of the pot base body, the processing difficulty of the concave part of the base body can be reduced, the processing time is shortened, the processing efficiency is improved, the processing cost is reduced, and the structural strength of the pot base body is ensured. Specifically, the ratio condition can be matched with the value range of the depth of the substrate concave part to jointly limit the size of the substrate concave part.

In a possible design, the sum of the bottom wall areas of all the base body concave parts is a first area, the sum of the top wall areas of all the base body convex parts is a second area, and the ratio of the first area to the second area is greater than or equal to 2 and less than or equal to 7.

In this design, the sum of the areas of the bottom walls of all the base concave portions is defined as a first area, the sum of the areas of the top walls of all the base convex portions is defined as a second area, and the ratio of the first area to the second area is specifically in a range of 2 to 7. The area that this lower limit value can guarantee the non-stick layer is enough big, and the area that does not have the non-stick layer is enough little, and the pan has sufficient antiseized performance. The upper limit value can ensure that the area of the first convex parts formed by the convex parts of the base body is large enough, namely the width of the first convex parts is large enough, and the distance between the first convex parts is small enough, so that the first convex parts can effectively support scraping of the turner, and abrasion of an anti-sticking layer is reduced.

A cookware provided according to some embodiments of the present invention is described below with reference to fig. 1 to 13.

As shown in fig. 7 and 13, an embodiment of an aspect of the present invention provides a pot 1, the pot 1 includes a pot body 100 and a non-stick layer 200, a target area of the pot body 100 is provided with first convex portions 110 and concave portions 130 which are alternately distributed, the target area includes at least a portion of an inner wall surface of the pot body 100, the pot body 100 includes: a pan base 150 and a stiffening portion 160, the stiffening portion 160 being located on an inner wall surface of the pan base 150, at least a portion of each first protrusion 110 being constituted by the stiffening portion 160; the non-stick layer 200 is located within the recess 130.

The embodiment of the utility model provides a pan 1 through set up non-stick layer 200 in the concave part 130 of pot body 100, can reduce the friction of instrument such as slice, soup ladle and non-stick layer 200 at the in-process of daily use pan 1, and then reduce the wearing and tearing to non-stick layer 200, help promoting pan 1's adhesion-resistant performance to the life of extension non-stick layer 200. In addition, the inner wall surface of the pot base 150 is provided with the hardening part 160, and at least a part of the first convex part 110 is formed by the hardening part 160, so that the surface hardness of the first convex part 110 can be improved, the surface hardness of the pot 1 is greatly enhanced, the non-stick layer 200 is prevented from falling off due to the fact that tools such as a slice and a soup ladle scratch the surface of the pot 1, and the service life of the pot 1 is prolonged; on the other hand, the stiffening part 160 can isolate the pan base 150 from air, so that the pan base 150 is prevented from yellowing and changing color in the heating process, and the use performance of the pan 1 is improved. Specifically, the first convex portions 110 and the concave portions 130 are alternately distributed, that is, the first convex portions 110 are distributed along the outer contour of the concave portions 130.

In some embodiments, the first protrusion 110 has a stiffener 160 at a sidewall thereof.

In this embodiment, since the first protrusions 110 and the recesses 130 are alternately distributed, the sidewalls of the first protrusions 110 also constitute the inner sidewalls of the recesses 130. Through making the lateral wall department of first convex part 110 have stiffened part 160, make the inside wall of concave part 130 have stiffened part 160 that promptly, can make this part stiffened part 160 cooperate with the non-stick layer 200 in the concave part 130, help strengthening the surface hardness of pan 1 at the inside wall of concave part 130, and then promote the structural stability of the non-stick layer 200 of setting in the concave part 130, reduce the risk that tools such as slice, soup ladle fish tail pan 1 surface, destroy concave part 130 structure and lead to non-stick layer 200 to peel off and drop, help improving the wear resistance of non-stick layer 200, the life of extension pan 1.

In some embodiments, the first protrusion 110 has a stiffening portion 160 at the top wall.

In this embodiment, the top wall of the first protrusion 110 is exposed to the outside, which not only forms the appearance of the pot 1, but also facilitates contact with a tool such as a slice or a spoon. By arranging the stiffening part 160 on the top wall of the first convex part 110 exposed outside, on one hand, the surface hardness of the top wall of the first convex part 110 can be improved, so that the surface hardness of the cookware 1 is greatly enhanced, tools such as a slice and a soup ladle are prevented from scratching the surface of the cookware 1, and the service life of the cookware 1 is prolonged; on the other hand, stiffened portion 160 can completely cut off pot base 150 and air, avoids pot base 150 to become yellow and change color in the process of being heated, helps to maintain the outward appearance of pan 1, has promoted the performance of pan 1.

It is understood that the first protrusion 110 may have the stiffening portion 160 only at the side wall, may have the stiffening portion 160 only at the top wall, and may have the stiffening portion 160 at both the side wall and the top wall as shown in fig. 13.

In some embodiments, the inner wall surface of the pot base 150 is provided with base protrusions 151 and base recesses 152 alternately distributed, and a portion of each first protrusion 110 is constituted by one base protrusion 151; the hardening part 160 includes a hardening layer continuously covering an area of the pot base 150 corresponding to the target area.

In this embodiment, an arrangement of the first convex portion 110 and the concave portion 130 is specifically defined. By providing the base convex portion 151 and the base concave portion 152 on the pot base 150 and specifically providing the stiffening portion 160 as a stiffening layer, the stiffening layer can be directly made to cover the region of the pot base 150 corresponding to the target region. On one hand, from the viewpoint of processing technology, as shown in fig. 9, a hardening layer is continuously covered on the region of the pan base 150 corresponding to the target region, as shown in fig. 11, a non-stick layer 200 is disposed on the surface of the continuous hardening layer, and as shown in fig. 13, the non-stick layer 200 on the top of the first protrusion 110 is removed by mechanical grinding, polishing, etc., which helps to simplify the processing of the hardening portion 160 and improve the processing efficiency; on the other hand, the hard layer can simultaneously strengthen the concave part 130, even if the non-stick layer 200 slightly falls off to expose the corresponding concave part 130, the damage of tools such as a slice and a soup ladle to the exposed concave part 130 can be reduced, the damage can be stopped in time, and the damage is prevented from further expanding to other areas. It is understood that the stiffening layer may further cover other regions of the pan base 150 in addition to continuously covering the region of the pan base 150 corresponding to the target region, so as to enhance the strength of the pan base 150.

In some embodiments, the inner wall surface of the pot base 150 is provided with base protrusions 151 and base recesses 152 alternately distributed, and a portion of each first protrusion 110 is constituted by one base protrusion 151; the stiffening portion 160 includes a stiffening layer that covers the inner wall of the substrate recess 152.

In this embodiment, another arrangement of the first convex portion 110 and the concave portion 130 is specifically defined. This arrangement differs from the former arrangement in that the hard coat covers only the inner walls of the base body recess 152, including the inner bottom wall and the inner side walls of the base body recess 152. Since the base convex portions 151 and the base concave portions 152 are alternately arranged, the inner side walls of the base concave portions 152 also constitute the side walls of the base convex portions 151, and in terms of the base convex portions 151, it is equivalent to covering only the side walls of the base convex portions 151 with the hard coat and not covering the top walls of the base convex portions 151 with the hard coat. On the one hand, the design scheme of the cooker 1 can be enriched, and the flexibility of product design is improved. On the other hand, from the viewpoint of the processing technique, in the process of removing the non-stick layer 200 by mechanical grinding, polishing, or the like, the removal thickness may be increased, and then the hardened layer on the top of the base convex portion 151 is also removed, so that the hardened layer no longer covers the base convex portion 151. Because the thickness of the non-stick layer 200 is thin, the requirement on the processing precision is high when only the non-stick layer 200 is removed, and the processing precision can be reduced by removing the hardened layer on the top of the convex part 151 of the base body at the same time, so that the processing difficulty is reduced, and the processing efficiency is improved.

That is, when the stiffening part 160 is a stiffening layer, the first convex part 110 may have the stiffening layer at both the side wall and the top wall, or may have the stiffening layer only at the side wall.

Alternatively, in the case where the pot base 150 is provided with the base convex portion 151 and the base concave portion 152, only the surface of the base convex portion 151 may be covered with the stiffening portion 160 to reduce the material consumption of the stiffening portion 160.

Alternatively, the pot base 150 may be configured to have a flat surface without the base convex portion 151 and the base concave portion 152, in which case, the stiffening portion 160 may be provided in the region of the pot base 150 corresponding to the target region, and the stiffening portion 160 may be configured to be the first convex portion 110, and the inner wall surface of the pot base 150 and the side wall surface of the first convex portion 110 together form the concave portion 130.

Alternatively, in the case that the pot base 150 is configured as a flat surface, the stiffening part 160 may be specifically configured as a stiffening layer, and the stiffening layer configures the first protrusion 110 and the concave part 130, which helps to improve the strength of the concave part 130 and simplify the processing of the pot base 150.

In some embodiments, the pan base 150 includes one or a combination of: an iron pan base body, a low-carbon steel pan base body and a stainless steel pan base body.

In this embodiment, the pan base 150 may specifically include one or a combination of an iron pan base, a mild steel pan base, and a stainless steel pan base. Wherein, the iron pan base body has the advantages of thin pan body and fast heat conduction; the low-carbon steel has good cold forming performance due to good plasticity and toughness, and can be processed into various pan body shapes; the stainless steel pot substrate has certain tolerance to acid and alkali, and is suitable for special cooking environment. By selecting different pan bases 150, different cooking requirements can be met. Alternatively, the pan base 150 may be made of a single layer material, and may also be made of a composite plate, such as a single layer fine iron plate, an iron-aluminum-iron three-layer composite plate, a single layer stainless steel, a stainless steel-aluminum-stainless steel composite plate, and the like.

In some embodiments, the hardbanding is a rust resistant hardbanding.

In this embodiment, specifically limited the stiffened layer and possessed rust-resistant function simultaneously, promptly rust-resistant stiffened layer to can promote the rust-resistant performance of pan 1 when increasing pan 1 hardness, help prolonging the life of pan 1.

In some embodiments, the hardbanding comprises one or a combination of: nitriding layer, metal layer.

In this embodiment, the hardening layer may specifically include one or a combination of a nitriding layer and a metal plating layer. Specifically, for an iron pan base body or a low-carbon steel pan base body, a nitriding layer can be arranged through a nitriding process, the surface hardness of the nitriding layer can reach more than HRC64(HRC is Rockwell hardness) and is far higher than HRC40 of stainless steel materials, and therefore scraping of the stainless steel turner can be effectively supported. In addition, the nitriding layer has certain non-stick property, so when the top wall of the first protrusion 110 has the nitriding layer, although the non-stick layer 200 is not arranged on the top of the first protrusion 110, the nitriding layer can also play a certain anti-sticking role, which is helpful for improving the overall non-stick property of the pot 1. For stainless steel pot substrates, a metal layer may be provided by a surface coating process, such as hard titanium coating, which may also achieve a hardness above HRC 64.

In some embodiments, the thickness of the non-stick layer 200 is less than the depth of the recess 130.

In this embodiment, by making the thickness of the non-stick layer 200 disposed in the concave portion 130 smaller than the depth of the concave portion 130, the surface of the non-stick layer 200 can be made lower than the top surface of the convex portion, thereby further reducing the friction between the non-stick layer 200 and tools such as a slice and a spoon during use, sufficiently reducing the wear of the tools on the non-stick layer 200, further improving the anti-sticking performance of the pot 1, and prolonging the service life of the non-stick layer 200.

In some embodiments, the target area includes at least a portion of the inner bottom wall of the pan body 100.

In this embodiment, the target area is specifically defined to include the entire inner bottom wall or a portion of the inner bottom wall of the pan body 100. Because in the use of pan 1, instruments such as slice, soup ladle mainly contact with the interior diapire of pot body 100, through set up concave part 130 on the interior diapire at pot body 100, can emphasize this regional antiseized performance, both can satisfy basic antiseized demand, can rationally reduce the processingquantity again, help promoting machining efficiency, reduce material consumption, reduce the processing cost. Further, since the central region of the inner bottom wall is in contact with a spatula, soup ladle or the like, the central region of the inner bottom wall may be specifically included when the target region includes a portion of the inner bottom wall of the pan body 100. It is understood that the target area may further comprise at least a portion of the inner sidewall of the pot body 100 to improve the anti-sticking performance of the pot 1 in its entirety.

In some embodiments, there are at least two recesses 130 of all recesses 130 in communication with each other.

In this embodiment, by making at least two recesses 130 communicate with each other, the non-stick layer 200 disposed in the recess 130 can also communicate therewith, thereby enlarging the continuous distribution area of the non-stick layer 200, and the more the recesses 130 communicate with each other, the larger the continuous distribution area of the non-stick layer 200 is, the adhesion force of the non-stick layer 200 can be enhanced, the non-stick layer 200 is prevented from locally falling off, the anti-sticking performance of the pot 1 is improved, and the service life of the non-stick layer 200 is prolonged. Correspondingly, for the first convex part 110 and the concave part 130 which are connected, the first convex part 110 is distributed along a part of the outer contour of the concave part 130, the position of the outer contour of the concave part 130, at which the first convex part 110 is not distributed, is the position at which the current concave part 130 is communicated with other concave parts 130, the first convex part 110 can be distributed continuously along the outer contour of the concave part 130 to leave an opening, or distributed at intervals along the outer contour of the concave part 130 to leave a plurality of openings, so that the two corresponding concave parts 130 are communicated through the openings. Specifically, all the recesses 130 may be divided into a plurality of groups, the number of each group of recesses 130 is at least one, and the recesses 130 of each group are integrally connected. When the concave portions 130 of each group are communicated, the concave portions 130 may be indirectly communicated with each other, or may be communicated with each other two by two. Further, the communication between any one of the concave portions 130 and at least one of the concave portions 130 adjacent thereto ensures that each of the concave portions 130 is not completely separated by the first convex portion 110. Further, all the recesses 130 communicate with each other, so that the non-stick layer 200 is integrally connected.

In some embodiments, the outer profile shape of the recess 130 includes one or a combination of: polygonal, circular, and irregular.

In this embodiment, the outer contour shape of the concave portion 130 may be a polygon, such as a triangle, a quadrangle, a hexagon, a circle, or a special shape. The non-stick layer 200 can comprise a pattern to simplify the structure and facilitate processing, and can also be composed of a plurality of patterns to realize rich and flexible non-stick layer 200 arrangement schemes, thereby reducing the falling possibility of the non-stick layer 200. It is understood that, in order to define the outer contour shape of the recess 130, when two adjacent recesses 130 are communicated, the channel connecting two recesses 130 may be provided with the non-adhesive layer 200 therein, but the channel is not received in the outer contour of the corresponding recess 130.

In some embodiments, the outer contour shape of the first protrusion 110 includes one or a combination of: polygonal, circular, and irregular.

In this embodiment, the outer contour shape of the first convex portion 110 may be a polygon, such as a triangle, a quadrangle, a hexagon, a circle, or a special shape. Can include a figure to simplify the structure, be convenient for processing, also can constitute by multiple figure, the combination of different shapes can make the connection between each first convex part 110 inseparabler, so that make the interval between two adjacent first convex parts 110 more reasonable, can better support the friction of instruments such as slice, soup ladle, protect the non-stick layer 200 in the concave part 130.

In some embodiments, the target area of the pan body 100 is further provided with a second protrusion 120, the second protrusion 120 being located at the bottom wall of the at least one recess 130; at least a portion of each second projection 120 is constituted by a stiffening portion 160.

In this embodiment, the bottom wall of at least one recess 130 is further provided with a second protrusion 120, and like the first protrusion 110, at least a part of the second protrusion 120 is also formed by a stiffening portion 160, and both of them serve as protrusions to reduce friction between a tool such as a slice or a spoon and the non-stick layer 200. Through set up second convex part 120 at the diapire of concave part 130, can cooperate with first convex part 110 for the interval between each concave part 130 is more reasonable, and can suitably enlarge the surface area of single concave part 130, thereby enlarge the continuous distribution area of non-stick layer 200, can strengthen non-stick layer 200's adhesive force, avoid non-stick layer 200 local drop, promoted the anti-adhesion performance of pan 1, prolonged non-stick layer 200's life. It is contemplated that, similar to the first protrusion 110, the outer profile shape of the second protrusion 120 includes one or a combination of: polygonal, circular, and irregular.

In some embodiments, the width of each base protrusion 151 is greater than or equal to 0.2mm and less than or equal to 1.5 mm.

In this embodiment, specifically, the width d1 of each base projection 151 takes a value in the range of 0.2mm to 1.5 mm. This lower limit value ensures that the first protrusion 110 formed of the base protrusion 151 has sufficient strength, and reduces damage to the first protrusion 110 when a tool such as a spatula scrapes the pot 1. Since the non-stick layer 200 is not present on the surface of the first projection 110, the anti-sticking performance of the pot 1 is lowered, and the upper limit value of the non-stick layer helps to ensure the anti-sticking performance of the pot 1 by limiting the area of the first projection 110 formed of the base projection 151. Further, the width d1 of the base protrusion 151 ranges from 0.2mm to 1mm, for example, 0.3mm, 0.5mm, and 0.8 mm. It is understood that the second protrusions 120 formed of the base protrusions 151 can also achieve the above-described effects.

In some embodiments, the distance between two adjacent base protrusions 151 is greater than or equal to 0.2mm and less than or equal to 4 mm.

In this embodiment, it is specifically defined that the distance L between two adjacent base protrusions 151 is in the range of 0.2mm to 4 mm. The lower limit value ensures that the substrate protrusions 151 have a sufficient distance therebetween to ensure that the non-stick layer 200 can be effectively adhered to the surface of the recess 130 when the non-stick layer 200 is disposed. This upper limit value ensures effective support of a tool such as a spatula, and contributes to reduction of damage to the non-stick layer 200 in the recess 130 by the tool such as a spatula during use. Further, the distance L between two adjacent base protrusions 151 ranges from 0.3mm to 3mm, for example, 0.4mm, 0.6mm, 1mm, 1.5mm, 2mm, 2.3mm, 2.5mm, and 2.8 mm.

In some embodiments, the depth of each substrate recess 152 is 0.2mm or greater and 0.8mm or less.

In this embodiment, specifically, the depth d2 of each base recess 152 ranges from 0.2mm to 0.8 mm. This lower limit ensures that the corresponding recess 130 is deep enough so that the surface of the non-stick layer 200 is below the top surface of the protrusion, reducing wear of the non-stick layer 200 by tools such as a spatula. This upper limit value can reduce the processing degree of difficulty of base member concave part 152, shortens the processing consuming time, promotes machining efficiency, helps reducing the processing cost. Further, the depth d2 of each base body recess 152 ranges from 0.3mm to 0.5mm, for example, 0.35mm, 0.4mm, 0.45 mm.

In some embodiments, the ratio of the depth of each base recess 152 to the thickness of the pan base 150 is equal to or less than 1/2.

In this embodiment, specifically, the depth of the base concave portion 152 is less than half of the thickness of the pan base 150, and the thickness of the pan base 150 is the thickness of the plate 153 used for manufacturing the pan base 150, so that the processing difficulty of the base concave portion 152 can be reduced, the processing time can be shortened, the processing efficiency can be improved, the processing cost can be reduced, and the structural strength of the pan base 150 can be ensured. Specifically, the ratio condition may cooperate with the range of the depth d2 of the base recess 152 to define the size of the base recess 152.

In some embodiments, the sum of the areas of the bottom walls of all the base recesses 152 is a first area, the sum of the areas of the top walls of all the base protrusions 151 is a second area, and the ratio of the first area to the second area is greater than or equal to 2 and less than or equal to 7.

In this embodiment, the sum of the areas of the bottom walls of all the base concave portions 152 is defined as a first area, and the sum of the areas of the top walls of all the base convex portions 151 is defined as a second area, and the ratio of the first area to the second area is specifically in a range of 2 to 7. The lower limit value can ensure that the area of the non-stick layer 200 is large enough, the area of the non-stick layer 200 is small enough, and the cooker 1 has enough anti-sticking performance. The upper limit value can ensure that the area of the first convex parts 110 formed by the base convex parts 151 is large enough, that is, the width of the first convex parts 110 is large enough, and the distance between every two adjacent first convex parts 110 is small enough, so that the first convex parts 110 can effectively support scraping of the slice, and abrasion of the non-stick layer 200 is reduced. It is understood that the second protrusions 120 formed of the base protrusions 151 can also achieve the above-described effects. It is understood that, in order to project the relationship between the area of the non-adhesive layer 200 and the area of the non-adhesive layer 200, when two adjacent substrate recesses 152 communicate with each other, the bottom wall area of the passage communicating the two substrate recesses 152 is also included in the first area. Further, the ratio of the first area to the second area ranges from 2 to 6, for example, 3, 4, and 5.

The specific embodiment is as follows:

the embodiment of the utility model provides a pot 1, pot base 150 internal surface is provided with the continuous base member concave part 152 of a plurality of parts and each other disconnected base member convex part 151, is equipped with the stiffened layer on the surface of base member concave part 152 and base member convex part 151, pot base 150 and stiffened layer constitute pot body 100, base member concave part 152 and the stiffened layer on surface constitute concave part 130 of pot body 100, base member convex part 151 and the stiffened layer on surface constitute the convex part of pot body 100 (including the first convex part 110 that distributes along the outline of concave part 130, and the second convex part 120 of the diapire of concave part 130 that distributes). The surface of the concave portion 130 is provided with the non-stick layer 200, and the surface of the non-stick layer 200 is lower than the top surface of the convex portion. By arranging the non-stick layer 200 in the concave part 130, and the surface of the non-stick layer 200 is lower than the top surface of the convex part, in the daily use process, tools such as a slice, a soup ladle and the like only rub against the top surface of the convex part, but basically do not rub against the surface of the non-stick layer 200, so that the abrasion of the non-stick layer 200 can be reduced, and the service life of the non-stick layer 200 can be prolonged. In addition, the surface setting of base member convex part 151 and base member concave part 152 adds the hard coat, can completely cut off pot base member 150 and air, avoids pot base member 150 surface to be heated the in-process and turn yellow and discolour, and secondly, the hardness that adds the hard coat is higher than stainless steel, can strengthen the hardness on pan 1 surface greatly, avoids tools such as stainless steel slice, soup ladle fish tail pan 1 surface and leads to non-stick layer 200 to drop, consequently can prolong the life of pan 1.

The material of the pan base 150 may be, in terms of composition, a ferrous material, low-carbon steel, or stainless steel. Structurally, the composite plate can be a single-layer material or a multi-layer composite plate, such as a single-layer fine iron plate, an iron-aluminum-iron three-layer composite plate, a single-layer stainless steel, a stainless steel-aluminum-stainless steel composite plate, and the like. The following description will be mainly made by taking a single-layer material as an example. For convenience of understanding, the pot 1 provided in the present embodiment is described below according to a process flow.

The process flow of the embodiment comprises the following steps: the sheet material 153 is provided with the base concave portion 152 → the pot base 150 is shaped → the surface of the pot base 150 is processed → the pot base 150 is provided with the hardened layer → the non-stick layer 200 is provided on the inner surface of the pot body 100 → the non-stick layer 200 on the surface of the convex portion is removed.

1. Plate 153 sets base recesses 152: as shown in fig. 1 and 2, on one side surface of the sheet 153, a part of the material on the surface of the sheet 153 is removed or pressed by a certain process means, so that a plurality of partially connected substrate recesses 152 are formed on the surface, and simultaneously, substrate protrusions 151 are formed at the positions where the substrate recesses 152 are not connected.

Alternatively, the substrate recess 152 may be formed by chemical etching, that is, a pattern is printed at the position of the substrate recess 152 to leave the position of the substrate protrusion 151, a protective layer is printed at the position of the substrate protrusion 151 and the remaining position of the surface of the plate 153, and the plate 153 is placed in an etching device for etching, so that the position of the substrate recess 152 forms a concave shape after the etching is completed. This is the technology that is mature in the industry at present.

Alternatively, the material at the position of the substrate concave part 152 can be removed by carving, that is, the surface of the plate 153 is cut by a carving device, so that the position of the substrate concave part 152 forms a concave shape. This is the technology that is mature in the industry at present.

Optionally, the substrate recesses 152 may also be formed by rolling, that is, the sheet 153 passes through a rolling device provided with a pair of rolling rods, the surface of the rolling rod is provided with corresponding protrusions, and the sheet 153 may be locally extruded, so that the substrate recesses 152 are formed on the surface of the sheet 153. This is the technology that is mature in the industry at present.

Optionally, the width d1 of the base protrusion 151 has a value range of: d1 is more than or equal to 0.2mm and less than or equal to 1mm, if d1 is too small, the strength of the base convex part 151 is poor, and the base convex part is easy to damage when being scraped by a turner, if d1 is too large, the area of the base convex part 151 is too large, and the non-stick performance of the pot 1 is poor because the surface of the hardened layer corresponding to the base convex part 151 is not provided with the non-stick layer 200.

Optionally, the depth d2 of the base body concave part 152 has a value range as follows: d2 is more than or equal to 0.3mm and less than or equal to 0.5mm, and d2 is more than or equal to 1/2T, wherein T is the thickness of the plate 153. If d2 is too small, the surface of the non-stick layer 200 is higher than or equal to the surface of the convex part after the non-stick layer 200 is disposed in the concave part 130, and the non-stick layer 200 is easily worn by a spatula, and if d2 is too large, the etching or engraving process time is prolonged, or the difficulty of the rolling process is increased, and the manufacturing cost is increased.

As shown in fig. 3 and 4, the plurality of base recesses 152 and the plurality of base protrusions 151 are distributed in the central area of the plate 153, and may cover the range corresponding to the inner surface of the pot 1 completely or partially.

The substrate recesses 152 are at least partially connected, that is, each substrate recess 152 is not completely separated by the substrate protrusion 151, which has the advantage that the non-adhesive layer 200 in the finally obtained recess 130 can be connected into a whole without being divided into small pieces, thereby enhancing the adhesion of the non-adhesive layer 200 and preventing the non-adhesive layer 200 from being partially peeled off.

The shape of each base concave portion 152 may be a polygon of three or more sides, such as a triangle, a hexagon, or the like, or may be a circle. The pattern can be composed of one pattern or a plurality of patterns.

The protrusions 151 of the base body are not connected to each other, so that the non-stick layer 200 in the final recess 130 can be better connected to each other, and the adhesion can be improved.

The base convex portion 151 may be polygonal, circular, or a combination of polygonal and circular. As shown in fig. 3 and 4, rectangular protrusions 151a and circular protrusions 151b may be provided, wherein the rectangular protrusions 151a and the circular protrusions 151b may be distributed along the basic unit contour 142 to form the first protrusion 110, and the circular protrusions 151b may be located in the concave portion 152 to form the second protrusion 120, so that the combination of different shapes may make the connection between the protrusions 151 closer, so that the distance between the protrusions and the resulting protrusion is more reasonable, and the friction of the tool such as a spatula or soup spoon may be better supported, and the non-stick layer 200 in the concave portion 130 may be better protected.

Optionally, the distance L between the base protrusions 151 ranges from: l is more than or equal to 0.3mm and less than or equal to 3mm, the larger L is, the larger the distance between the finally obtained convex parts is, tools such as a slice can not be effectively supported, the non-stick layer 200 in the concave part 130 can be scratched by the tools such as the slice in the using process, and the L is less than 0.3mm, the distance between the finally obtained convex parts is too small, so that the non-stick layer 200 can not be effectively attached to the surface of the concave part 130 when the non-stick layer 200 is arranged.

If the above-described etched, engraved, or rolled processed region is regarded as being composed of a plurality of repeated basic cells 140, the area ratio S between the area S1 of the base concave portion 152 and the area S2 of the base convex portion 151 in each basic cell 140 can be calculated. As shown in fig. 5, the dotted line is the basic unit contour line 142, the contour of the basic unit 140 is a quadrangle, and accordingly, the outer contour of the base concave portion 152 is also a quadrangle, the base convex portion 151 constituting the first convex portion 110 includes a rectangular base convex portion 151a and a circular base convex portion 151b, wherein the circular base convex portion 151b is located at the vertex of the quadrangle, the rectangular base convex portion 151a extends along the side of the quadrangle, an opening is formed between the circular base convex portion 151b and the rectangular base convex portion 151a, so that the base concave portion 152 communicates with the surrounding base concave portion 152, and the opening area in the basic unit contour line 142 is also received in the area S1 of the base concave portion 152.

The area S can be given by: s is more than or equal to 2 and less than or equal to 6, namely S1/S2 and less than or equal to 2 and less than or equal to 6. The larger the S is, the larger the area of the non-stick layer 200 is, the smaller the area of the non-stick layer 200 is, the better the non-stick property of the cookware 1 is, otherwise, the worse the non-stick property is, but an excessively large area ratio may cause an excessively small area of the convex portion, that is, an excessively small width of the convex portion and an excessively large interval between the convex portions, thereby causing the convex portion not to effectively support scraping of the slice, and causing the non-stick layer 200 to be easily worn.

2. The pan base 150 is shaped: as shown in fig. 6 and 7, the sheet 153 provided with the base concave 152 and the base convex 151 is made into the shape of the pot base 150 by a die drawing process, a spinning process, a hydraulic drawing process, or the like, and meanwhile, excess material at the mouth of the pot base 150 is removed by a die trimming process, a special lathe edge process, or the like, so that the base concave 152 and the base convex 151 are located on the inner surface of the pot base 150.

3. Surface treatment of the pan base 150: the method comprises the steps of carrying out all surface treatment before arranging a hardening layer on the pan base body 150, generally grinding and polishing the inner surface and the outer surface of the pan base body 150, and removing the defects of rust, impurities, scratches and the like on the surface to form a smoother and uniform surface for the pan base body 150, so as to prepare for arranging the hardening layer.

In another embodiment, the method further comprises sand blasting the inner surface of the pot base 150 to increase the roughness of the inner surface, so as to improve the adhesion of the non-stick layer 200 disposed in a later process.

In another embodiment, the method further comprises the steps of removing oil from the pan base 150, cleaning the pan base, and the like.

4. The pan base 150 is provided with a hard layer: as shown in fig. 8 and 9, a hard layer is provided on the inner surface of the pot base 150 to obtain the pot body 100. The hardened layer completely covers the surfaces of the substrate recesses 152 and the substrate protrusions 151, forming recesses 130 and protrusions. Alternatively, the hard coating layer may cover the inner surface of the pot base 150 except the base concave portion 152 and the base convex portion 151.

For the pot base body 150 made of iron materials or low-carbon steel materials, a nitriding layer can be arranged through a nitriding process, the surface hardness of the nitriding layer can reach more than HRC64 and is far higher than HRC40 made of stainless steel materials, and therefore scraping of the stainless steel slice can be effectively supported.

For the stainless steel pan body, a metal layer can be arranged by a surface plating process, such as hard titanium plating, and the hardness can also reach more than HRC 64.

5. The inner surface of the pan body 100 is provided with a non-stick layer 200: as shown in fig. 10 and 11, the non-stick layer 200 is provided on the surfaces of the concave portion 130 and the convex portion by means of gas spraying, electrostatic adhesion, or the like. The thickness of the non-stick layer 200 is less than the depth of the recess 130, i.e., the upper surface of the non-stick layer 200 is lower than the top surface of the protrusion.

The non-stick layer 200 may be made of fluorine paint or ceramic paint.

6. Removing the non-stick layer 200 on the surface of the convex part: as shown in fig. 12 and fig. 13, the non-stick layer 200 on the surface of the convex portion is removed by mechanical grinding, polishing, etc., in the process, because the surface of the non-stick layer 200 in the concave portion 130 is lower than the top surface of the convex portion, the grinding or polishing device will not contact with the non-stick layer 200 in the concave portion 130, and will only contact with the non-stick layer 200 on the surface of the convex portion, so that a small amount of the non-stick layer 200 on the surface of the convex portion is preferentially removed, and the non-stick layer 200 in the concave portion 130 will remain, thus forming the surface of the non-stick layer 200 on the inner surface of the pot 1, which is spaced from the convex portion.
