In any of the above technical solutions, the middle of the composite bottom plate is configured with a positioning portion, and the positioning portion is surrounded by a positioning hole.

The middle part of the composite bottom sheet is provided with the positioning part which can play a positioning role, so that the precise alignment of the composite bottom sheet and the pan bottom body is ensured, and the production efficiency of products is improved. The positioning part is surrounded with a positioning hole, so that the positioning is realized conveniently by concave-convex matching with the pan bottom body. Moreover, the positioning part is arranged in the middle of the composite bottom plate, so that the balance of stress between the composite bottom plate and the pan bottom body is facilitated, the size of the positioning part is reduced on the basis of ensuring the accurate alignment of the composite bottom plate and the pan bottom body, and the structure of the composite bottom plate is simplified; and the positioning hole in the middle part can be used for accommodating marks such as trademark patterns or characters of cookware, and the attractiveness and the grade of the product are improved. Furthermore, at least one of the end face of the positioning part facing the pot bottom body and the hole wall of the positioning hole is attached to the pot bottom body, so that the tight combination of the inner side edge of the composite bottom sheet and the pot bottom body is ensured, the inner side edge of the composite bottom sheet is prevented from tilting, cracking or even falling off, the combination strength of the composite bottom sheet and the pot bottom body is improved, and the use reliability of the pot is improved.

In any one of the above technical solutions, the through hole is a circular hole.

The through hole adopts the circular port, simple structure, and the machine-shaping of being convenient for, and the structure is regular, and is handsome in appearance, is favorable to improving the aesthetic property of product. Of course, the through-hole is not limited to a circular hole, and may be a polygonal hole, an elliptical hole, a special-shaped hole, or the like.

In any of the above technical solutions, the diameter of the through hole is in the range of 0.5mm to 3 mm; and/or the hole spacing of the adjacent through holes is in the range of 2mm to 10 mm; and/or the ratio of the total area of the orthographic projection of all the through holes on the bottom surface of the pan bottom body to the total area of a graph defined by the outline of the orthographic projection of the composite bottom plate on the bottom surface of the pan bottom body is within the range of 0.05-0.2; and/or the ratio of the area of the orthographic projection of the through hole on the bottom surface of the pot bottom body to the area of the orthographic projection of the double-bottom protrusion on the bottom surface of the pot bottom body is in the range of 0.01 to 0.1.

The diameter of the through hole is limited within the range of 0.5mm to 3mm, such as 0.5mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm and the like, so that the phenomenon that the through hole is too small to cause too weak effect of the through hole is avoided, and the phenomenon that the use performance of the compound bottom plate is influenced by too large hollow area of the compound bottom plate caused by too large diameter of the through hole is also avoided. Such as: for the scheme that the composite bottom plate comprises the magnetic conductive sheet, the phenomenon that the magnetic conductive performance of the magnetic conductive sheet is influenced due to the fact that the hollow area of the magnetic conductive sheet is too large due to the fact that the diameter of the through hole is too large can be avoided, and the electromagnetic heating power of the cooker is influenced too much. Of course, the diameter of the through hole is not limited to the above range, and may be adjusted as needed in an actual production process.

The hole spacing of the adjacent through holes is limited in the range from 2mm to 10mm, such as 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm and the like, so that the problem that the use performance of the complex negative is influenced due to the fact that the hollow area of the complex negative is too large due to too small hole spacing is avoided, and the problem that the effect of the through holes is too weak due to too large hole spacing is also avoided. Of course, the hole pitch of the adjacent through holes is not limited to the above range, and may be adjusted as needed in an actual production process.

When the thickness of the double-bottom plate is ignored, the total area of the orthographic projections of all the through holes on the bottom surface of the pot bottom body can be simply recorded as the total area of the through holes; when the thickness and the hollow part of the double negative plate are neglected, the total area of the graph surrounded by the contour line of the orthographic projection of the double negative plate on the bottom surface of the pan bottom body can be recorded as the area of the double negative plate. The ratio of the total area of the through holes to the area of the composite bottom plate is limited within the range of 0.05-0.2, such as 0.05, 0.1, 0.15, 0.2 and the like, so that the phenomenon that the effect of the through holes is too weak due to too small total area of the through holes is avoided, and the phenomenon that the service performance of the composite bottom plate is influenced due to too large hollow area of the composite bottom plate due to too large total area of the through holes is also avoided.

The ratio of the orthographic projection area of the through hole on the bottom surface of the pot bottom body to the orthographic projection area of the double-bottom protrusion on the bottom surface of the pot bottom body is limited within the range of 0.01 to 0.1, such as 0.01, 0.03, 0.05, 0.07, 0.09, 1 and the like, so that the phenomenon that the through hole is too small to cause the too weak effect of the through hole is avoided, and the phenomenon that the use performance of the double-bottom plate is influenced by the too large hollow area of the double-bottom plate caused by the too large through hole is also avoided.

It is to be understood that orthographic projection means that the parallel projection lines are perpendicular to the plane of projection. Therefore, the orthographic projection of the through hole, the double-bottom protrusion or the double-bottom film on the bottom surface of the pot bottom body refers to the projection generated on the bottom surface of the pot bottom body by taking the bottom surface of the pot bottom body as a projection plane and irradiating the through hole, the double-bottom protrusion or the double-bottom film by using a parallel projection line perpendicular to the projection plane.

In any of the above technical solutions, an orthographic projection of the double-bottom protrusion on the bottom surface of the pot bottom body is polygonal.

The orthographic projection of the double-bottom protrusion on the bottom surface of the pot bottom body is polygonal, such as triangular, square, pentagonal, hexagonal and the like, the structure is simple, and the processing and forming are convenient.

Further, when the orthographic projection of the double-bottom bulges on the bottom surface of the pot bottom body is a polygon (especially a regular polygon), and the multiple double-bottom bulges are distributed at even intervals, two opposite edges of the two adjacent double-bottom bulges can adopt a parallel distribution mode, so that the pot bottom formed in this way is regular and attractive in shape, and the use experience of a user is favorably improved.

In the technical scheme, the orthographic projection of at least part of the boss on the bottom surface of the pot bottom body is in a regular hexagon shape.

A plurality of regular hexagon bosss are even interval distribution on the bottom surface of pot bottom, compare in other polygons, and the pot bottom molding that forms is more pleasing to the eye. It will be appreciated that, subject to the size limitations of the land distribution area, at least a portion of the lands of the outer periphery may not form a complete regular hexagon, and at least a portion of the lands of the inner periphery may not form a complete regular hexagon.

In the above technical solution, the height of the boss is in the range of 0.2mm to 4 mm.

The height of boss is limited in the range of 0.2mm to 4mm, the condition that the height of boss is too low to lead to too weak strengthening effect or to lead to the increase of the heated area of the cookware over-small is avoided, and the condition that the bottom surface of the pot bottom and the pot wall part are too far away from the heat source to influence the heating of the cookware when the cookware is used due to too high height of boss is also avoided. Of course, the height of the boss is not limited to the above range, and may be adjusted as needed in the actual production process.

In any of the above technical solutions, the pot opening defined by the top end of the pot wall portion is circular; the top surface of the pot bottom body is in a regular polygon shape.

The pot is improved in shape, the top surface of the bottom of the pot (namely the bottom of the pot on the inner surface of the pot) is designed into a regular polygon, and the top opening of the wall of the pot (namely the pot opening surrounded by the top end of the wall of the pot) is kept circular. Therefore, the part of the pot bottom corresponding to the corner of the regular polygon forms a corner part, and the part between the adjacent corner parts is relatively straight. Compared with the curvature of the transition part between the pot wall part and the pot bottom part of the round pot, the curvature of the transition part between the relatively straight part of the pot bottom part and the pot wall part is obviously increased, when food in the pot is pushed to the inner side wall (namely the inner side wall of the concave part) of the part of the pot wall part, the food does not slowly rise along with the side wall with smooth transition, but turns over and falls along with the side wall which suddenly becomes steep, so that the food is more easily turned over, the food is uniformly heated, and the cooking effect is improved; the part of the pot wall part corresponding to the corner part of the pot bottom part forms an outwards convex structure, compared with the smooth surface of a round pot, food is easy to gather at the convex structure when the food in the pot is poured, and the convex structure can play a certain flow guiding role, so that the food is prevented from spilling, the food is not easy to fall outside the pot when the food is put in the pot, the food waste is avoided, and the table top is also prevented from being polluted by the food. Moreover, the scheme is suitable for pouring treatment of soup food and also suitable for pouring treatment of block food. Meanwhile, the existing open fire heat source or non-open fire heat source (such as an electromagnetic heating heat source) is usually a circular heat source, the circumferential structure of the regular polygon-like heat source is relatively regular and is relatively close to the shape of the circular heat source, and the circumferential uniform heating of food in the pot is facilitated. The round pot opening is kept, so that a universal handle is convenient to select, universal configuration of the pot cover is facilitated, universal packaging is convenient to select, special handles or packaging do not need to be selected according to the shape of the pot, and the product cost is reduced; and because when the vegetable juice is poured, the soup juice easily flows down along the pot opening, and the pot opening is arranged to be circular, the accumulation of residues can be reduced while the heat conductivity of the pot is improved, and the pot is convenient to clean.

It is understood that regular polygon-like refers to a shape resembling a regular polygon. Such as: replacing at least a part of straight edges with curve segments on the basis of the regular polygon; or, on the basis of the regular polygon, the connection mode of at least one part of adjacent straight edges is changed into fillet connection; or, on the basis of the regular polygon, at least one part of straight edges is replaced by curve segments, and at least one part of two adjacent edges are connected by adopting round corners. For the cookware, the top surface of the bottom of the cookware is difficult to be made into a strict regular polygon, adjacent sides are generally connected through round corners, and when the radius of the round corners is very small, the regular polygon is basically equal to the regular polygon.

In any of the above technical solutions, the complex bottom plate includes a magnetic conductive sheet.

The composite bottom sheet comprises a magnetic conductive sheet, so that the cookware can be used for heating by open fire and can also be used for electromagnetic heating heat sources such as an induction cooker, and the application range of the cookware is enlarged. Of course, the double-bottom plate is not limited to include the magnetic conductive sheet, and may also include a heat conductive sheet for improving the heat transfer efficiency of the pot, a reinforcing sheet for improving the strength of the pot, and the like.

In any one of the above technical solutions, the double bottom plate is in a regular polygon shape, the outer periphery of the double bottom plate is located inside the outer periphery of the pot bottom body, and the outer periphery of the double bottom plate is parallel to the outer periphery of the pot bottom body.

In the scheme, the pan bottom body and the composite bottom sheet are both in the shape of a regular polygon, and the shapes of the regular polygon and the regular polygon are consistent, but the area of the composite bottom sheet is smaller than that of the pan bottom body, so that the shape is regular and attractive, a certain reserved space is provided for deformation of the composite bottom sheet, and the composite bottom sheet is prevented from falling off.

The pan bottom body 25 is connected with the bottom of the pan wall part 1, and the bottom sheet 27 is attached on the bottom surface 254 of the pan bottom body 25. The part of the double bottom sheet 27 protrudes in the direction away from the pan bottom body 25 to form a double bottom protrusion 273 (as shown in fig. 7). The double-bottom protrusion 273 is provided with a through hole 274, as shown in fig. 5.

The utility model provides a pan, bottom of a boiler 2 include bottom of a boiler body 25 and double-bottom piece 27, form double-bottom pan, are favorable to further optimizing the performance of pan. The composite bottom sheet 27 may include, but is not limited to, a magnetic conductive sheet, so that the cookware may be used for both open fire heating and electromagnetic heating sources such as an induction cooker.

The double-bottom plate 27 is partially protruded to form a double-bottom protrusion 273, the bottom surface and the side surface of the double-bottom protrusion 273 can be heated, so that the heating area of the double-bottom plate 27 is increased, and the heating efficiency of the cooker is improved; and the arrangement of the double-bottom bulge 273 is also beneficial to increasing the contact area of the double-bottom sheet 27 and the pan bottom body 25, thereby improving the binding force of the double-bottom sheet 27 and the pan bottom body 25.

Meanwhile, the double-bottom plate 27 is provided with the through hole 274, and in the heating process, the bottom surface of the double-bottom plate 27, the hole wall of the through hole 274 and the part of the pot bottom body 25 corresponding to the through hole 274 can be contacted with an open fire heat source, so that the heating area of the pot can be further improved, and the heating uniformity of the pot can be further improved.

Moreover, in the case that the complex bottom plate 27 includes the magnetic conductive plate, the arrangement of the complex bottom protrusion 273 increases the magnetic conductive area of the magnetic conductive plate, but the distance between the complex bottom protrusion 273 and the heating element is closer than that between other parts of the complex bottom plate 27, and the magnetic field of the electromagnetic induction is stronger, so that the magnetic conductive plate is not uniform enough, and the through hole 274 is arranged on the complex bottom protrusion 273, so that the resistance of the complex bottom plate 27 at the through hole 274 can be increased, and the induced current can be dispersed, so that the heating uniformity of the complex bottom plate 27 can be improved, and the heating power of the complex bottom plate 27 can also be improved; and the magnetic conduction piece is usually great in the noise of work, and the noise of magnetic conduction piece can also be reduced to the setting of through-hole 274 to improve the use comfort level of pan.

In some embodiments, as shown in fig. 1, the top of the pot wall 1 is rounded to form a pot opening 111. The top surface 21 (shown in fig. 2) of the pan bottom body 25 is in a regular polygon shape.

Thus, the part of the pot bottom 2 corresponding to the corner of the regular polygon forms a corner part, and the part between the adjacent corner parts is relatively straight. Compared with the curvature of the transition part between the pot wall part 1 and the pot bottom part 2 of the round pot, the curvature of the transition part between the relatively straight part of the pot bottom part 2 and the pot wall part 1 is obviously increased, when food in the pot is pushed to the inner side wall of the part of the pot wall part 1, the food does not slowly rise along with the side wall with smooth transition, but turns over and falls down along with the side wall which suddenly becomes steep, so that the food is more easily turned over, the food is heated uniformly, and the cooking effect is improved; the part of the pot wall part 1 corresponding to the corner part of the pot bottom part 2 forms an outwards convex structure, compared with the smooth surface of a round pot, food is easy to gather at the convex structure when the food in the pot is poured, and the convex structure can play a certain flow guiding role, so that the food is prevented from being scattered, the food is not easy to fall outside the pot when the food is put in the pot, the food waste is avoided, and the table top is also prevented from being polluted by the food. Moreover, the scheme is suitable for pouring treatment of soup food and also suitable for pouring treatment of block food.

The round pot opening 111 is convenient for selecting a universal handle 3, is also beneficial to the universal configuration of a pot cover and is also convenient for selecting a universal package, and a special handle 3 or package is not required to be selected according to the shape of the pot, so that the product cost is reduced; and because when the vegetable juice is poured, the soup juice easily flows down along the pot opening 111, and the part provided with the pot opening 111 is circular, the accumulation of residues can be reduced while the heat conductivity of the pot is improved, and the pot is convenient to clean.

It is understood that regular polygon-like refers to a shape resembling a regular polygon. Such as: replacing at least a part of straight edges with curve segments on the basis of the regular polygon; or, on the basis of the regular polygon, the connection mode of at least one part of adjacent straight edges is changed into fillet connection; or, on the basis of the regular polygon, at least one part of straight edges is replaced by curve segments, and at least one part of two adjacent edges are connected by adopting round corners.

Wherein, for the pan, it is difficult to make the top surface 21 of the pan bottom 2 into a strict regular polygon, adjacent sides are generally connected by round corners, and when the radius of the round corners is very small, the regular polygon is basically equal to the regular polygon.

In some embodiments, the pan bottom body 25 is provided with pan bottom protrusions 253, as shown in fig. 7. The double bottom plate 27 includes a double bottom main body 272 and double bottom protrusions 273 (shown in fig. 4 and 7) connected to the double bottom main body 272.

The boss 29 is formed by the pan bottom protrusion 253 of the pan bottom body 25 and the double bottom protrusion 273 of the double bottom sheet 27, so that the contact area between the double bottom sheet 27 and the pan bottom body 25 is effectively increased, the binding force between the double bottom sheet 27 and the pan bottom body 25 is further improved, the falling probability of the double bottom sheet 27 is reduced, and the strength and the use reliability of the cooker are further improved.

Moreover, the surface area of the composite bottom plate 27 is increased by the composite bottom protrusions 273, which is beneficial to improving the service performance of the composite bottom plate 27.

In any of the above embodiments, a portion of the pan bottom body 25 is inserted into the through hole 274.

A part of the pan bottom body 25 is arranged in the through hole 274, so that on one hand, the contact area between the pan bottom body 25 and the composite bottom plate 27 is increased, the binding force between the pan bottom body 25 and the composite bottom plate 27 is further increased, and the heat transfer efficiency between the composite bottom plate 27 and the pan bottom body 25 is also improved; on the other hand, the distance between the pan bottom body 25 and the heat source is reduced, which is beneficial to increasing the heating area of the pan bottom body 25 and improving the heating efficiency of the pan bottom 2.

Further, the number of the double-bottom protrusions 273 is plural, and the plural double-bottom protrusions 273 are uniformly spaced apart from each other, as shown in fig. 5. The number of the through holes 274 on at least part of the double-bottomed projections 273 is at least two as shown in fig. 5.

Protruding 273 in a plurality of compound ends is even interval distribution, then every compound protruding 273 in end's size is less relatively, the machine-shaping of both being convenient for, also be convenient for on the bottom surface of pot bottom 2 a plurality of small-size bosss 29 of homodisperse, this is favorable to avoiding 2 local stress concentration in pot bottom, has both further improved 2 intensity in pot bottom, is favorable to further reducing the risk that the pan is heated and takes place to warp, has also further increased the heated area of pan, is favorable to further improving culinary art effect.

In addition, the number of the through holes 274 on at least part of the double-bottom protrusions 273 is at least two, which further increases the resistance of the double-bottom protrusions 273, effectively disperses the induced current, further improves the heating efficiency and the heating uniformity of the double-bottom sheet 27, and can further reduce the working noise of the double-bottom sheet 27.

In some embodiments of the present invention, the through-holes 274 are circular holes, as shown in fig. 5.

The through holes 274 are circular holes, so that the structure is simple, the processing and forming are convenient, the structure is regular, the appearance is attractive, and the attractiveness of a product is improved.

Of course, the through hole 274 is not limited to a circular hole, and may be a polygonal hole, an elliptical hole, a special-shaped hole, or the like.

Further, the diameter of the through hole 274 is in the range of 0.5mm to 3 mm.

The diameter of the through hole 274 is limited within the range of 0.5mm to 3mm, such as 0.5mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm and the like, so that the phenomenon that the through hole 274 is too small to cause too weak action of the through hole 274 is avoided, and the phenomenon that the hollow area of the composite bottom plate 27 is too large to affect the use performance of the composite bottom plate 27 due to too large diameter of the through hole 274 is also avoided. Such as: for the scheme that the composite bottom plate 27 comprises the magnetic conductive sheet, the phenomenon that the magnetic conductive performance of the magnetic conductive sheet is affected due to the fact that the hollow area of the magnetic conductive sheet is too large due to the fact that the diameter of the through hole 274 is too large can be avoided, and the electromagnetic heating power of the cooker is affected too much.

Of course, the diameter of the through hole 274 is not limited to the above range, and may be adjusted as needed in an actual production process.

In any of the above embodiments, the hole pitch of adjacent through holes 274 is in the range of 2mm to 10 mm.

The hole spacing of the adjacent through holes 274 is limited within the range of 2mm to 10mm, such as 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm and the like, so that the influence on the use performance of the composite bottom plate 27 caused by the too large hollow area of the composite bottom plate 27 due to too small hole spacing is avoided, and the too weak effect of the through holes 274 caused by too large hole spacing is also avoided. Here, the hole pitch of the adjacent through holes 274 refers to a minimum distance between the adjacent two through holes 274.

Of course, the hole pitch of the adjacent through holes 274 is not limited to the above range, and may be adjusted as needed in an actual production process.

In any of the above embodiments, the ratio of the total area of the orthographic projection of the plurality of through holes 274 on the bottom surface 254 of the pan bottom body 25 to the total area of the figure surrounded by the outline of the orthographic projection of the composite bottom plate 27 on the bottom surface 254 of the pan bottom body 25 is in the range of 0.05 to 0.2.

When the thickness of the bottom sheet 27 is ignored, the total area of the orthographic projections of the through holes 274 on the bottom surface 254 of the pan bottom body 25 can be simply recorded as the total area of the through holes 274; when the thickness and the hollow-out portion of the double-bottom plate 27 are neglected, the total area of the figure enclosed by the contour line of the orthographic projection of the double-bottom plate 27 on the bottom surface 254 of the pan bottom body 25 can be recorded as the area of the double-bottom plate 27. The ratio of the total area of the plurality of through holes 274 to the area of the composite bottom plate 27 is limited within the range of 0.05 to 0.2, such as 0.05, 0.1, 0.15, 0.2 and the like, so that the phenomenon that the effect of the through holes 274 is too weak due to too small total area of the through holes 274 is avoided, and the phenomenon that the service performance of the composite bottom plate 27 is affected due to too large hollow area of the composite bottom plate 27 due to too large total area of the through holes 274 is avoided.

Of course, the ratio of the total area of the plurality of through holes 274 to the area of the composite base sheet 27 is not limited to the above range, and may be adjusted as needed in the actual production process.

It is to be understood that orthographic projection means that the parallel projection lines are perpendicular to the plane of projection. Therefore, the orthographic projection of the through hole, the double-bottom protrusion or the double-bottom film on the bottom surface 254 of the pan bottom body 25 refers to the projection generated on the bottom surface 254 of the pan bottom body 25 by using the bottom surface 254 of the pan bottom body 25 as a projection plane and irradiating the through hole, the double-bottom protrusion or the double-bottom film by using a parallel projection line perpendicular to the projection plane.

Further, the cross section of the boss 29 is polygonal, as shown in fig. 4, and the number of the bosses 29 is plural, and the plural bosses 29 are distributed at even intervals.

The cross section of the boss 29 is polygonal, and the orthographic projection of the boss on the bottom surface 254 of the pot bottom body 25 is also polygonal, such as triangular, square, pentagonal, hexagonal and the like, so that the structure is simple and the processing and forming are convenient.

A plurality of bosss 29 are even interval distribution, then every boss 29's size is less relatively, both the machine-shaping of being convenient for, also be convenient for on the bottom surface of pot bottom portion 2 evenly disperse a plurality of small-size bosss 29, this is favorable to avoiding 2 local stress concentration of pot bottom portion, has both further improved 2 intensity of pot bottom portion, is favorable to further reducing the risk that the pan is heated and takes place to warp, has also further increased the heated area of pan, is favorable to further improving culinary art effect.

Further, when the cross section of the boss 29 is polygonal (especially regular polygon), and the plurality of bosses 29 are uniformly distributed at intervals, two opposite edges of two adjacent bosses 29 can adopt a parallel distribution mode, so that the pot bottom formed in this way is neat and attractive in shape, and is beneficial to improving the use experience of users.

In one embodiment, at least some of the bosses 29 are regular hexagonally shaped in cross-section, as shown in FIG. 4.

The regular hexagonal bosses 29 are evenly distributed on the bottom surface of the pot bottom 2 at intervals, and compared with other polygons, the pot bottom formed by the regular hexagonal bosses is more attractive in appearance. It will be appreciated that, subject to the size limitations of the distribution area of the bosses 29, at least a portion of the bosses 29 on the outer periphery may not form a complete regular hexagon, and at least a portion of the bosses 29 on the inner periphery may not form a complete regular hexagon.

Wherein the ratio of the area of the orthographic projection of the through hole 274 on the bottom surface of the pot bottom 2 to the area of the orthographic projection of the boss 29 on the bottom surface of the pot bottom 2 is in the range of 0.01 to 0.1.

The ratio of the orthographic projection area of the through hole 274 on the bottom surface of the pot bottom 2 to the orthographic projection area of the boss 29 on the bottom surface of the pot bottom 2 is limited to be within the range of 0.01 to 0.1, such as 0.01, 0.03, 0.05, 0.07, 0.09, 1 and the like, so that the phenomenon that the through hole 274 is too small to cause the too weak effect of the through hole 274 is avoided, and the phenomenon that the hollow area of the composite bottom plate 27 is too large to influence the use performance of the composite bottom plate 27 due to the too large through hole 274 is also avoided.

Of course, the ratio of the area of the orthographic projection of the through hole 274 on the bottom surface of the pot bottom 2 to the area of the orthographic projection of the boss 29 on the bottom surface of the pot bottom 2 is not limited to the above range, and can be adjusted as needed in the actual production process.

Further, the height P of the boss 29 is in the range of 0.2mm to 4 mm.

The height of the boss 29 is limited in the range from 0.2mm to 4mm, so that the situation that the reinforcing effect is too weak or the heating area of the cookware is too small due to too low height of the boss 29 is avoided, and the situation that the bottom surface of the pot bottom 2 and the pot wall part 1 are too far away from a heat source to influence the heating of the cookware when the cookware is used due to too high height of the boss 29 is also avoided. Of course, the height of the boss 29 is not limited to the above range, and may be adjusted as needed in an actual production process.

In any of the above embodiments, the complex bottom sheet 27 includes a magnetic conductive sheet.

The composite bottom sheet 27 comprises a magnetic conductive sheet, so that the cookware can be used for heating by open fire and can also be used for electromagnetic heating heat sources such as an induction cooker, and the application range of the cookware is enlarged.

In some embodiments, further, the middle of the bottom plate 27 is configured with a positioning portion, which encloses a positioning hole 271, as shown in fig. 4.

The middle part of the double-bottom plate 27 is provided with a positioning part which can play a positioning role, so that the precise alignment of the double-bottom plate 27 and the pan bottom body 25 is ensured, and the production efficiency of the product is improved. The positioning part is surrounded with a positioning hole, which is convenient for realizing positioning by concave-convex matching with the pan bottom body 25.

Moreover, the positioning part is arranged in the middle of the composite bottom plate 27, so that the balance of stress between the composite bottom plate 27 and the pan bottom body 25 is facilitated, the size of the positioning part is reduced on the basis of ensuring the accurate alignment of the composite bottom plate 27 and the pan bottom body 25, and the structure of the composite bottom plate 27 is simplified; and the positioning hole in the middle part can be used for accommodating marks such as trademark patterns or characters of cookware, and the attractiveness and the grade of the product are improved.

Specifically, the first lines 211 are straight line segments (as shown in fig. 2) or curved line segments, and the shape formed by the M first lines 211 has an inscribed circle 23 (as shown in fig. 2). The second line 212 is an arc line segment, as shown in fig. 2, and two adjacent first lines 211 are connected by the second line 212 in a rounded manner. M is greater than or equal to 3.

In this scheme, first lines 211 are the thread, and M first lines 211 outline the shape of similar regular polygon, and second lines 212 are the transition connecting portion of two adjacent first lines 211, and the transition connecting portion is the fillet line for top surface 21 of pot bottom 2 is similar M limit shape.

Of course, the diameter of the inscribed circle 23 is not limited to the above range, and may be adjusted as needed in an actual production process.

Further, the radius R of the second line 212 is equal to or greater than 10mm and equal to or less than the radius of the inscribed circle 23.

The radius of the second line 212 is limited in the range between 10mm and the radius (namely L/2) of the inscribed circle 23, so that the phenomenon that the position is too sharp to cause food residue due to the fact that the radius of the second line 212 is too small is avoided, and the phenomenon that the shape of the pot bottom is too close to a circle to affect the food stir-frying effect due to the fact that the radius of the second line 212 is too large is also avoided.

The following is a detailed description of the wok as an example and a comparison with the prior art.

The existing pot is difficult to turn over food in the using process, and when the food is poured and contained, the food is scattered in the pot and is easy to pour out of the plate, so that the problems of food waste and hearth cleaning are caused.

Particularly, current pan when turning over the fried food, because of the bottom of a boiler and the lateral wall transition is big and be the round bottom, can't turn over food, lead to food to heat inhomogeneous, in addition when falling the dish, because of the small-bore at the bottom of the pan is big, food can't gather, lead to food unrestrained top of a kitchen range.

In the prior art, a solution is not available for turning dishes temporarily, and the existing solution for the problem of turning dishes is to press a diversion notch on a pot opening 111, but the diversion notch is too small, so that only soup and juice liquid can be diverted, and the guidance for blocky food cannot be provided.

The example describes a cookware comprising a pot body and a handle 3. The pot body comprises a pot bottom (namely a pot bottom part 2) and a pot wall (namely a pot wall part 1). The top end of the pot wall forms a pot opening 111. The handle 3 is fixedly connected to the pot wall and is specifically arranged in the direction with the bulge on the pot wall.

The pot opening 111 is round.

The shape of the pot bottom is a regular polygon-like shape consisting of N identical lines (namely, a first line 211) and M identical fillet lines (namely, a second line 212), wherein: n is equal to or more than 3 and is a positive integer; the first line 211 may be a curved line or a straight line; the first lines 211 and the round lines are arranged at intervals and connected end to end; the M first lines 211 may have one inscribed circle 23.

The pot wall is in a transition shape, a bulge is formed on the side wall in the direction of a circular line, and the height H of the bulge ranges from 2mm to 15 mm.

The pot described in this example has the advantages that the pot bottom is a regular polygon, the curvature radius of the connecting part of the first line 211 and the pot wall of the regular polygon is large, when food is pushed to the side wall in the direction, the food is easy to turn over, the pot wall part 1 corresponding to the round line direction of the regular polygon is provided with the convex structure 13 protruding outwards, the food is easy to gather at the convex structure 13 when being poured out, and the pot is not easy to fall outside the pot.

The circular through holes 274 and the hexagonal bosses 29 on the pot bottom are beneficial to increasing the contact area of the magnetic conducting sheets and the pot bottom, so that the mutual friction force is increased, but when the number of the through holes 274 is increased and the diameter of the through holes 274 is increased, the magnetic conducting surface of the magnetic conducting sheets is reduced, so that the electromagnetic heating power is influenced, the ratio of the total area of all the circular through holes 274 to the area of the magnetic conducting sheets on the magnetic conducting sheets is 0.05-0.2, and the ratio of the area of the circular through holes 274 to the area of the hexagonal bosses 29 is 0.01-0.1, the magnetic conducting sheets have better magnetic conducting performance and have larger adhesive force with the pot bottom.
