[0031] The existing composite bottom pot has multiple layers of metal on the bottom wall to prevent the bottom of the pot from being too thin and deforming and arching during heating. In some related technologies, the bottom wall of the three-layer composite pot includes a first stainless steel plate layer, an aluminum plate layer, and a second stainless steel plate layer arranged outward in sequence; in some related technologies, the bottom wall of the three-layer composite pot includes a stainless iron plate layer, an aluminum plate layer, and a stainless steel plate layer arranged outward in sequence; in some related technologies, the bottom wall of the three-layer composite pot includes a stainless steel plate layer, an aluminum plate layer, and a titanium plate layer arranged outward in sequence; in some related technologies, the bottom wall of the three-layer composite pot includes a first titanium plate layer, an aluminum plate layer, and a second titanium plate layer arranged outward in sequence.

[0032] However, the innermost layer of the existing composite pot is made of smooth plate material, and the innermost bottom wall of stainless steel, stainless iron or titanium is made integrally with the pot body, has a smooth surface, poor positioning and matching effect with the second layer of aluminum plate, and poor composite bonding.

[0033] For this reason, Figures 1 to 3As shown, the composite bottom pattern pot proposed by the utility model comprises a pot body 100 and a composite layer 200 arranged at the bottom of the pot body 100, wherein the pot body 100 comprises a first pot bottom layer 110, and the composite layer 200 is arranged on the outer wall of the first pot bottom layer 110 and is integrally connected to the first pot bottom layer 110. Specifically, the first pot bottom layer 110 is provided with a plurality of first protrusions 111, and the first protrusions 111 are integrally connected to the first pot bottom layer 110, and the plurality of first protrusions 111 are distributed on the outer wall of the first pot bottom layer 110. Further, the composite layer 200 comprises a first adhesive layer 210 and a second pot bottom layer 220, and the two ends of the first adhesive layer 210 are respectively in contact with the first pot bottom layer 110 and the second pot bottom layer 220. In addition, the melting point of the first adhesive layer 210 is lower than the melting points of the first pot bottom layer 110 and the second pot bottom layer 220, so as to composite the second pot bottom layer 220 and the first pot bottom layer 110. In some embodiments, the first pot bottom layer 110 is stainless iron or stainless steel, the first adhesive layer 210 is aluminum, and the second pot bottom layer 220 is stainless iron or stainless steel. In some embodiments, the first pot bottom layer 110 is stainless iron or stainless steel, the first adhesive layer 210 is aluminum, and the second pot bottom layer 220 is titanium steel. In some embodiments, the first pot bottom layer 110 is titanium steel, the first adhesive layer 210 is stainless steel or stainless iron, and the second pot bottom layer 220 is titanium steel. In some applications, in addition to the three-layer composite bottom pan, there are also five-layer composite bottom pans and seven-layer composite bottom pans. It is easy to understand that the composite layer 200 can be set in multiple groups. For example, the five-layer composite bottom pan is based on the three-layer composite bottom pan, and the third pot bottom layer and the second pot bottom layer 220 are composited on the outside of the second pot bottom layer 220 through the second adhesive layer. In some composite processing, the high temperature and high pressure processing environment will make the first adhesive layer 210 play a role similar to glue, and composite the first pot bottom layer 110 and the second pot bottom layer 220. It should be noted that in some processing operations, the first adhesive layer 210 only needs to be partially melted on the surface to achieve the bonding function. By spreading the first protrusions 111 on the outer wall of the first pot bottom layer 110, the first adhesive layer 210 can penetrate between the multiple first protrusions 111, and the combination with the first pot bottom layer 110 is more tightly, and the degree of combination of the composite processing is higher, thereby improving the thermal conductivity of the bottom wall of the finished pot body 100 and achieving better use effect.

[0034] In some embodiments, the first adhesive layer is a smooth structure (not shown in the figure), such as both end surfaces of the first adhesive layer are smooth structures, and in processing and positioning applications, one end surface directly abuts against the lower wall surface of the first protrusion, and the other end surface directly abuts against the upper wall surface of the second pot bottom layer. Figure 1 and Figure 2As shown, the end surface of the first adhesive layer 210 is provided with a first groove 211, and there are a plurality of first grooves 211, and the plurality of first grooves 211 are arranged throughout the first adhesive layer 210. Therefore, in the processing positioning application, since the end surface of the first adhesive layer 210 has a concave-convex structure, the friction between the first pot bottom layer 110 or the second pot bottom layer 220 is greater, and it is not easy to shift after stacking and positioning. Figure 2 The first groove 211 is disposed on the inner end surface of the first adhesive layer 210, and the shape of the first groove 211 matches the shape of the first protrusion 111. During the positioning process of the first bottom pot layer 110 and the first adhesive layer 210, the first protrusion 111 can be embedded in the first groove 211 to achieve accurate positioning of the two, and the first bottom pot layer 110 and the first adhesive layer 210 will not be relatively offset. Similarly, in some embodiments, referring to Figure 1 The first groove 211 is disposed on the outer end surface of the first adhesive layer 210, and the friction between the first groove 211 and the second bottom layer 220 is greater, so that the first groove 211 is not easily displaced after being stacked and positioned. Furthermore, the second bottom layer 220 is provided with a plurality of second protrusions 221, which are integrally connected to the second bottom layer 220 and are distributed throughout the end surface of the second bottom layer 220. For example, referring to Figure 2 When the second protrusion 221 is arranged on the inner end surface of the second pot bottom layer 220, it has a similar function to the first protrusion 111. On the one hand, the first adhesive layer 210 can penetrate between the multiple second protrusions 221 in a high-temperature processing environment, and is more tightly combined with the second pot bottom layer 220, and the degree of bonding in composite processing is higher, thereby improving the thermal conductivity of the bottom wall of the finished pot body 100 and achieving better use effect; on the other hand, when the outer end surface of the first adhesive layer 210 is provided with a first groove 211 matching the shape of the second protrusion 221, the second protrusion 221 can be embedded in the first groove 211, thereby realizing precise positioning of the two, and the second pot bottom layer 220 and the first adhesive layer 210 will not be relatively offset. In some embodiments, the outer end surface of the second pot bottom layer is also provided with a second protrusion (not shown in the figure), so that when the composite bottom pot is placed on a support platform such as a table or countertop, the friction between the outer wall of the second pot bottom layer and the end surface of the support platform is large, and the composite bottom pot is not easy to slide; or, when the composite bottom pot is placed on a cooking support rack, the friction between the outer wall of the second pot bottom layer and the cooking support rack is large, and the composite bottom pot is not easy to slide, and the placement is more stable. It is easy to understand that the first groove 211 can be provided on both the inner end surface and the outer end surface of the first adhesive layer 210. In some applications, the first groove 211 is formed by rolling, and the first groove 211 is processed on both side end surfaces of the first adhesive layer 210, or, when the thickness of the first adhesive layer 210 is small, the first groove 211 arranged in a staggered manner is processed on both side end surfaces of the first adhesive layer 210 after rolling.

[0035] like Figure 1As shown, in some embodiments of the utility model, a plurality of first protrusions 111 form connecting grooves 1101, and the connecting grooves 1101 are distributed vertically and horizontally and are connected in a mesh structure. On the one hand, the first adhesive layer 210 can penetrate into the connecting grooves 1101 and flow in the connecting grooves 1101 during the composite processing, so as to evenly fill the connecting grooves 1101 of the entire mesh structure, further improving the bonding effect with the first bottom layer 110. It is easy to understand that the arrangement and function of the second protrusions 221 can refer to the arrangement and function of the first protrusions 111, which can make the first adhesive layer 210 evenly fill the gaps between the second protrusions 221 during the composite processing, thereby improving the overall bonding effect of the first bottom layer 110, the first adhesive layer 210 and the second bottom layer 220, which will not be described in detail here. On the other hand, in some manufacturing processes, grooves are formed on the plate surface after roll forming of a metal plate, wherein the extension path of the grooves depends on the roller shaft used in the rolling process, and the grooves are separated by the first protrusions 111. Then, the plate with the first protrusions 111 is formed into the structure of the pot body 100 by stamping, so that the first pot bottom layer 110 of the pot body 100 is covered with the first protrusions 111. In this regard, when the connecting grooves 1101 formed between the multiple first protrusions 111 are all connected, that is, the convex strips set by the pressure roller are all connected, it is possible to process all connected grooves on the surface of the plate. At this time, since the corresponding convex strips set by the pressure roller are all connected, the overall structural rigidity is better and not easy to collapse, which effectively increases the service life of the pressure roller and can relatively reduce the processing cost.

[0036] Furthermore, the pot body 100 includes a pot body 120, and the pot body 120 is provided with a plurality of pattern protrusions 101, the shape of the pattern protrusions 101 is the same as or different from the shape of the first protrusions 111, the pattern protrusions 101 are integrally connected to the pot body 120, and the plurality of pattern protrusions 101 are distributed on the outer wall of the pot body 120. The pattern protrusions 101 and the first protrusions 111 can be processed together in a rolling process, and optionally, the shape of the pattern protrusions 101 is the same as the shape of the first protrusions 111, and the processing and manufacturing are more convenient. Moreover, the rolling process is a processing method that does not remove materials, and the plate after rolling processing has a higher density and a higher hardness, so that the outer wall of the pot body 120 of the pot body 100 has better anti-scratch performance. In addition, the arrangement regularity of the pattern protrusions 101 that are distributed can improve the aesthetics of the pot body 100.

[0037] In some embodiments, the shapes of the plurality of first protrusions are all the same, and the plurality of first protrusions are arranged in an array on the outer wall of the pot body. In some embodiments, the shapes of the plurality of first protrusions are different. Figure 1As shown, the first protrusion 111 includes a first-shaped protrusion 1111 and a second-shaped protrusion 1112, the shape of the first-shaped protrusion 1111 and the shape of the second-shaped protrusion 1112 are different, and the first-shaped protrusion 1111 and the second-shaped protrusion 1112 are arranged alternately. For example, the first-shaped protrusion and the second-shaped protrusion are square and polygonal, respectively, or the first-shaped protrusion and the second-shaped protrusion are two irregular shapes (not shown in the figure). In some embodiments of the utility model, the first protrusion 111 includes a first-shaped protrusion 1111 and a second-shaped protrusion 1112, the shapes of the first-shaped protrusion 1111 and the second-shaped protrusion 1112 are different, and the first-shaped protrusion 1111 and the second-shaped protrusion 1112 are arranged alternately. Specifically, referring to the first protrusion 111 located on the first bottom layer 110, the first-shaped protrusion 1111 is in a first elliptical shape along a cross section perpendicular to the thickness direction of the first-shaped protrusion 1111, and the long axis of the first elliptical shape is arranged horizontally; the second-shaped protrusion 1112 is in a second elliptical shape along a cross section perpendicular to the thickness direction of the second-shaped protrusion 1112, and the long axis of the second elliptical shape is arranged longitudinally; the first-shaped protrusion 1111 and the second-shaped protrusion 1112 are arranged with a strong regularity and better overall aesthetics. Optionally, the first-shaped protrusion 1111 and the second-shaped protrusion 1112 are arranged in a staggered manner in the horizontal direction, or the first-shaped protrusion and the second-shaped protrusion are arranged in a staggered manner in the longitudinal direction (not shown in the figure); or, the first-shaped protrusion and the second-shaped protrusion are arranged in a staggered manner in both the horizontal direction and the longitudinal direction, that is, the first-shaped protrusion is surrounded by the second-shaped protrusion, and the second-shaped protrusion is surrounded by the first-shaped protrusion (not shown in the figure).

[0038] In some embodiments, the first protrusions have the same shape but are of different sizes. For example, the first protrusions include a first-shaped protrusion and a second-shaped protrusion, the shape of the first-shaped protrusion and the shape of the second-shaped protrusion are the same and scaled, and the first-shaped protrusion and the second-shaped protrusion are arranged alternately. For example, the first-shaped protrusion and the second-shaped protrusion are heart-shaped patterns of different sizes, waves of different thicknesses, etc.

[0039] It is easy to understand that in addition to being divided into a first-shaped protrusion and a second-shaped protrusion, the first protrusion can also have more shapes depending on the design. For example, the first protrusion also includes a third-shaped protrusion (not shown in the figure) that is different from both the first-shaped protrusion and the second-shaped protrusion.

[0040] In some embodiments, according to different methods of processing or forming the first protrusions, the ends of the first protrusions are spherical structures (not shown in the figure), and there are corresponding gaps between adjacent first protrusions. Figure 1 As shown, the end surface of the first protrusion 111 located on the first pot bottom layer 110 is a plane. When the pot body 100 is a round pot, the end surface of the first protrusion 111 located on the pot body 120 is an arc surface that matches the arc of the pot body 120.

[0041] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
