Therefore, how to provide a container with more uniform heating to improve the food sticking, sticking and yellowing of the bottom of the container is a problem to be solved.

Disclosure of Invention

The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

It is therefore an object of the present invention to provide a container assembly.

Another object of the present invention is to provide a heating apparatus.

In order to achieve the above object, the present invention provides a container assembly, comprising: the container body comprises an inner side wall and an inner bottom wall, wherein concave-convex grains are formed in the inner side wall and the inner bottom wall, each concave-convex grain comprises a bulge and a groove, and each groove is formed by the bulge and the inner wall of the container body in a surrounding mode; the non-stick coating is arranged in the groove; the projection area of the non-stick coating on the inner side wall is a, the area of the inner side wall is S1, the projection area of the non-stick coating on the inner bottom wall is b, and the area of the inner bottom wall of the container body is S2, wherein a/S1 is less than or equal to b/S2.

The container assembly provided by the invention comprises a container body, and a non-stick coating and concave-convex grains which are arranged on the container body. And the inner wall of the container body is provided with protrusions, grooves are formed between different protrusions, and concave-convex lines are formed by the grooves and the protrusions. In the actual production process, the protrusions may be provided on the inner wall of the container body, and then the grooves may be defined by the protrusions and the inside of the container body, i.e., the non-stick coating may be provided between one or more protrusions. The setting, because the non-stick coating is located in the recess, can be with non-stick coating adduction in the recess, when using cooking utensil like this, just can form the protection to the non-stick coating through the arch between the recess to just be difficult for taking place fish tail and wearing and tearing non-stick coating, also make non-stick coating more not fragile, and then alright guarantee the non-stick performance of interior pot etc. container, improved container assembly's life. In addition, because the heat conduction performance of the non-stick coating is poorer than that of the container material, a/S1 is less than or equal to b/S2, namely the area ratio of the projection area a of the non-stick coating on the inner side wall to the inner side wall is smaller than the area ratio of the projection area b of the non-stick coating on the inner bottom wall to the inner bottom wall of the container body, the heat conduction area of the side wall of the container body can be relatively increased, and the heat at the bottom of the container body can be conducted to the side wall of the container body more, so that the food materials in the whole container assembly are heated more uniformly. On the other hand, the heat can be promoted to be transferred from the bottom wall to the side wall, the concentration of the heat on the bottom wall is reduced, the falling risk of the non-stick coating is reduced, the non-stick coating at the further bottom wall is relatively high in occupancy, and the non-stick performance at the bottom wall can be improved. Further, the dispersibility of the air flowing from the bottom wall to the side wall can be promoted, and the aggregation of the air at the bottom wall can be improved, so that the baking of the container assembly to the food can be improved, the uniformity of the temperature above the container can be improved, and the baking heating efficiency of the container assembly can be improved.

The projection areas in the application are all orthographic projection areas, for example, the projection area of the non-stick coating on the inner side wall is the projection area of the non-stick coating projected along the direction perpendicular to the inner side wall.

In addition, the container assembly in the technical scheme provided by the application can also have the following additional technical characteristics:

in any one of the above technical schemes, the container body comprises a bottom wall and a side wall, the bottom wall and the side wall are connected through an arc structure, the area of the inner wall surface of the arc structure is S3, the projection area of the non-stick coating on the arc structure is c, wherein a/S1 is less than or equal to c/S3 is less than or equal to b/S2.

In this technical scheme, the diapire and the lateral wall of the container body are excessively connected through the arc structure. As the temperature at the arc-shaped structure is generally higher, and a/S1 is less than or equal to c/S3 is less than or equal to b/S2, namely the area ratio of the non-stick coating on the container body is reduced from the side wall to the arc-shaped structure and then from the side wall to the bottom wall. And because the temperature of arc transition portion department is higher, consequently the aforesaid setting for the area ratio of non-stick coating on the arc structure can form the transition between diapire and lateral wall, makes the non-stick coating area ratio of lateral wall department low like this, promotes heat to lateral wall department transmission, on the other hand, can avoid the non-stick coating of arc structure department too much, can promote the heat of arc structure department to the food material transmission, thereby reduce the heat concentration of this department, reduce the whereabouts of non-stick coating.

In any of the above technical solutions, the side wall of the container body includes a first side wall section and a second side wall section that are connected to each other, the first side wall section is located above the second side wall section, the average thickness of the first side wall section is smaller than that of the second side wall section, the projected area of the non-stick coating on the first side wall section is e, the area of the inner wall surface of the first side wall section is S4, the projected area of the non-stick coating on the second side wall section is f, and the area of the inner wall surface of the second side wall section is S5, where e/S4 is less than or equal to f/S5.

In this solution, the side wall of the container body is composed of at least two segments. Wherein the average thickness of the side wall section at the upper side is thinner, i.e. the side wall thickness of the container body is smaller as it goes above. The projection area ratio of the non-stick coating on the first side wall section with higher position is smaller than that of the non-stick coating on the second side wall section with lower position, so that the thickness of the side wall and the area ratio of the non-stick coating are adapted, namely, the corresponding non-stick coating is smaller at the position with thinner side wall thickness. This kind of setting helps strengthening the intensity of container body on the one hand, and on the other hand helps increasing the heat conduction of container body on the lateral wall, and on the other hand helps promoting the heat transfer of thick department, reduces the heat and concentrates, reduces the risk that non-stick coating drops, finally helps promoting the dispersion of the hot air in the container body, improves the homogeneity of the internal temperature of container.

In any of the above technical solutions, the concave-convex pattern includes a plurality of cells, and the cells include cell protrusions and grooves surrounded by the cell protrusions.

In this solution, the relief pattern is formed by a plurality of elementary cells, and each elementary cell comprises a ring of closed or sealed projections (i.e. cell projections) and a recess surrounded by the projections. For example, the cells may be of regular polygonal configuration. In general, the protrusions of the unit cells are closed structures, wherein, in order to enable communication between adjacent unit cells, openings may be formed on the side walls of the unit cell protrusions, so that the unit cell protrusions become non-closed structures with the openings.

Further, along the height direction of the container body, the area surrounded by the protrusions of the unit cells is reduced from bottom to top. Further, the projected area of the protrusions of the unit cells on the inner wall surface of the container body is d, and the ratio of the sum of d to S1 on the inner wall surface is larger than that on the inner bottom wall surface. Further, the value of d gradually increases from bottom to top in the height direction of the container body.

In the technical scheme, the area enclosed by the bulges is reduced from bottom to top, namely the area of the grooves in the cells is smaller upwards, namely the whole cells are smaller upwards, so that when the cells are sequentially connected and distributed, the arrangement density of the cells is higher and denser, namely the number of the cells is higher, and in the concave-convex lines, the area ratio of the bulges is higher and bigger, so that the heat transfer area of the upper end of the container body can be increased, and the heat conducting performance is more balanced. Meanwhile, the area ratio of the protrusions on the side wall is larger than that of the protrusions on the bottom wall, so that the accumulation of heat on the lower portion can be reduced, the risk that the non-stick coating falls off is reduced, the heat conduction efficiency of the side wall can be increased, and the heat conduction of the container body is balanced.

The projection area of the cell protrusions and the like on the inner wall surface of the container body is the projection area of the cell protrusions and the like projected in the direction perpendicular to the inner wall, namely, the projection areas of the application are all the vertical projection areas.

Further, the side wall surface of the container body is increased from the bottom to the top, the protruding area of the upper end of the side wall is larger than that of the lower end of the side wall in the unit area, and the arrangement has the advantages that the contact area between the protrusions at the upper end of the container and food is effectively increased, and meanwhile, the coating area is small, because the protruding area is large, the area of the groove is reduced, the coating area is relatively reduced, and the heat conduction effect is good because the coating area is small. This kind of setting makes the heat conduction effect on container body upper portion be greater than the heat conduction effect of lower part, also can understand that the protruding area on upper portion is big, consequently, heat radiating area is big, and the non-stick coating area on upper portion is little, consequently, the heat conduction effect is better, can compensate the lateral wall upper portion from the two aspects and transfer heat more slowly like this, the influence that brings, make the upper portion and the lower part of food can be heated more even some to can improve the scratch resistance on container body upper portion, reduce the destruction of scoop etc. to the non-stick coating, make the effect that the food culinary art comes out can be better.

Further, the circumferential width of the groove surrounded by the cells is a first width t1, the first width t1 is reduced from bottom to top along the height direction of the container body, and/or the first width t1 of the cells on the side wall is smaller than the first width t1 of the cells on the bottom wall. Further, the longitudinal width of the groove surrounded by the cells is a second width t2, the second width t2 increases from bottom to top along the height direction of the container body, and/or the second width t2 of the cells on the side wall is greater than the second width t2 of the cells on the bottom wall.

In the technical scheme, the circumferential width of the grooves in the cells, namely the circumferential width of the grooves on the side wall, is reduced from bottom to top, namely the cells are more slender when being arranged above the container body, the first width t1 of the cells on the side wall is smaller than the first width t1 of the cells on the bottom wall, namely the cells on the side wall are more slender than the cells on the bottom wall, so that the arrangement density of the cells on the side wall can be increased, the arrangement density of the cells above the side wall is increased, the heat conducting performance of the side wall is better when being arranged above, the heat conducting efficiency of the side wall is increased on the whole, and the heat conducting performance of the container body is more uniform. In addition, the arrangement is good in heat conduction performance above the side wall, so that accumulation of heat at the lower part is reduced, the risk of falling of a lower coating is reduced, and the non-sticking performance is improved. In addition, the convex area of the upper part has a relatively large occupied area, so that the protection of the non-stick coating can be enhanced, and the scratch resistance of the upper part of the container to food materials can be improved. The non-stick coating above the side wall can be divided into finer structures, so that the non-stick coating above the side wall can be firmly attached to the wall of the container, and the peeling risk of the coating on the upper part of the container is reduced. The arrangement can also reduce the stress concentration phenomenon of the container body at the contact position of the food material and the container body, and improve the corrosion resistance.

In addition, when the container body is used in an air fryer, namely, when the container body is used in an air frying environment, heat can be promoted to flow to the lower part of the container, heating of food materials is promoted, resistance of the heat to the upper part of the container is improved, heat dispersion is improved, and uniformity of flow of hot air in a container cavity is improved, so that uniformity of heating of the food materials can be improved.

Further, the ratio of the first width t1 of the cells on the bottom wall to the first width t1 of the cells on the side wall is 1.2 or more and 1.5 or less. This arrangement makes the width of the cells on the side walls and the gap on the bottom wall relatively moderate. And the gap is too large, so that the rejection rate is increased, heat accumulation is easy to generate at the connecting position of the bottom wall and the side wall, and the corrosion resistance of the container body is reduced. The gap is too small, and at this time, heat at the bottom wall is easily accumulated, so that the risk of peeling of the non-stick coating at the bottom wall is increased.

In any of the above technical solutions, the container body includes a bottom wall and a side wall, the bottom wall and the side wall are connected by an arc structure, the relief path includes a plurality of cells, and the cells include cell protrusions and grooves surrounded by the cell protrusions; the projection area of the nonstick coating in the cells on the inner wall surface of the container body is c, the change rate of c of at least one cell on the side wall compared with the change rate of c of at least one cell on the arc-shaped structure is a first change rate, the change rate of c of at least one cell on the arc-shaped structure compared with the change rate of c of at least one cell on the bottom wall is a second change rate, and the first change rate is larger than the second change rate. Further, the projected area of the cell protrusions on the inner wall surface of the container body is d, the rate of change of d of at least one cell on the side wall compared with d of at least one cell on the arc-shaped structure is a third rate of change, the rate of change of d of at least one cell on the arc-shaped structure compared with d of at least one cell on the bottom wall is a fourth rate of change, and the third rate of change is larger than the fourth rate of change.

In the technical scheme, the projection area of the non-stick coating in the cell on the inner wall of the container body is changed, specifically, the projection area of the non-stick coating on the bottom wall of the same cell is larger than the projection area of the non-stick coating on the inner wall of the arc-shaped structure, and the projection area of the non-stick coating on the inner wall of the arc-shaped structure is larger than the projection area of the non-stick coating on the side wall. However, the area change of the non-stick coating is not too large, and optimally, when the bottom wall is transited to the arc-shaped structure, the area change rate of the non-stick coating in the unit cell is smaller than that when the arc-shaped structure is transited to the side wall, and/or, the projection area of the protrusion in the unit cell on the inner wall of the container body is d, and when the arc-shaped structure is transited to the side wall, the change rate of the projection area d is larger than that when the bottom wall is transited to the arc-shaped structure. The non-stick coating can be distributed better by the arrangement, so that the heat conduction efficiency of the side wall can be improved, and the heat conduction of the container body is more balanced. Specifically, the change rate of the side wall is large, the rapid transfer of energy at the arc-shaped structure and the bottom wall to the side wall can be promoted, the accumulation of heat at the arc-shaped structure and the bottom wall is reduced, the risk of peeling of the non-stick coating is reduced, and the non-stick property at the arc transition and the bottom wall is improved. In addition, the rate of change of arc structure department is less, on the one hand can improve the shaping performance of product, on the other hand, avoids the heat to appear when the heat is passed from the bottom to the lateral wall, has improved the corrosion resistance of arc structure department. Meanwhile, through the combined action of the two with larger change rate at the side wall and smaller change rate at the arc-shaped structure, the corrosion resistance of the bottom wall and the arc transition part can be improved, and meanwhile, the heat transfer at the side wall is promoted; in addition, the flow of heat to the lower part of the container can be promoted, the heating of food materials is promoted, the resistance of the heat to the upper part of the container is improved, the heat dispersion is improved, the uniformity of the flow of hot air in the container cavity is improved, and the uniformity of the heating of the food materials is improved.

Further, on the side wall higher than 1/2 of the height of the container body, the projection area of the non-stick coating in the cell on the inner wall of the container body is c1, the projection area of the non-stick coating in the cell on the inner wall of the container body is c2, the projection area of the non-stick coating in the cell on the inner wall of the container body is c3, and the projection area of the non-stick coating in the cell on the inner wall of the container body is |c1-c2|/c2> |c2-c3|/c3. The arrangement can promote the protection of the upper part of the container to the non-stick coating, improve the scratch resistance of the container body, improve the heat transition of the connecting area of the bottom wall and the radian transition part, reduce the phenomenon of heat accumulation and improve the corrosion resistance. Meanwhile, the heat of the upper part of the container can be promoted to flow to the lower part of the container, the heating of food materials is promoted, the resistance of the heat to the upper part of the container is improved, the heat dispersion is improved, the uniformity of the flow of hot air in the cavity of the container is improved, and the uniformity of the heating of the food materials is improved.

Further, on the side wall higher than 1/2 of the height of the container body, the projection area of the cell projection on the inner wall of the container body is d1, the projection area of the cell projection on the inner wall of the container body is d2 in the area where the arc structure is lower than 1/2 of the arc structure, and the projection area of the cell projection on the inner wall of the container body is d3 in the bottom wall of the container body, wherein, d1-d 2/d 2> |d2-d3|/d3. The arrangement can promote the protection of the upper part of the container to the non-stick coating, improve the scratch resistance of the container, improve the heat transition of the connecting area of the bottom wall and the radian transition part, reduce the phenomenon of heat accumulation and improve the corrosion resistance. Meanwhile, the heat of the upper part of the container can be promoted to flow to the lower part of the container, the heating of food materials is promoted, the resistance of the heat to the upper part of the container is improved, the heat dispersion is improved, the uniformity of the flow of hot air in the cavity of the container is improved, and the uniformity of the heating of the food materials is improved.

The arrangement can be provided with more cells on the side wall, so that the heat conduction effect of the side wall is better, and the overall heat conduction effect of the container body can be balanced.

Further, the arrangement density of the cells increases from bottom to top on the side wall surface of the container body along the height direction of the container body. The arrangement can enable the more the cells on the side wall to be above, so that the heat conduction effect of the upper side of the side wall is better, and the overall heat conduction effect of the container body can be balanced.

Further, in the height direction of the container body, the height of the protrusions of the unit cells in the thickness direction of the side walls of the container body is reduced from bottom to top.

In addition, since the heat conduction property of the non-stick coating 18 is inferior to that of the container material, a/S1 is less than or equal to b/S2, that is, the area ratio of the projected area a of the non-stick coating 18 on the inner side wall surface to the inner side wall surface is smaller than the area ratio of the projected area a of the non-stick coating 18 on the inner bottom wall surface to the inner bottom wall surface of the container body 12, the heat conduction area of the side wall 124 of the container body 12 can be relatively increased, and the heat at the bottom of the container body 12 can be conducted to the side wall 124 of the container body 12 more, so that the food materials in the whole container assembly 1 can be heated more uniformly. On the other hand, the heat transfer from the bottom wall 122 to the side wall 124 can be promoted, the concentration of the heat on the bottom wall 122 can be reduced, the risk of the release of the non-stick coating 18 can be reduced, the non-stick performance at the bottom wall 122 can be improved by further increasing the occupancy of the non-stick coating 18 at the bottom wall 122. Further, the dispersibility of the flow of air from the bottom wall 122 to the side wall 124 can be promoted, and the accumulation of air at the bottom wall 122 can be improved, whereby the baking of the food material by the container assembly 1 can be improved, and the uniformity of the temperature above the container can be improved, and the baking heating efficiency of the container assembly 1 can be improved.

Ltoreq.c/S3. Ltoreq.b/S2.

In this embodiment, the bottom wall 122 and the side wall 124 of the container body 12 are over-connected by an arcuate structure 126. While the temperature at the arcuate structure 126 is generally relatively high, and a/S1 c/S3 b/S2, which is indicative of the area ratio of the non-stick coating 18 on the container body 12, decreases in sequence from the side wall 124 to the arcuate structure 126 and then to the bottom wall 122. Due to the fact that the temperature of the arc-shaped transition portion is high, the area occupied by the non-stick coating on the arc-shaped structure 126 can form transition between the bottom wall 122 and the side wall 124, so that on one hand, the area occupied by the upper side of the arc-shaped structure 126 is low, heat transfer to the upper side can be promoted, on the other hand, excessive coating on the arc-shaped structure 126 can be avoided, heat transfer to food materials on the arc-shaped structure 126 can be promoted, heat concentration at the arc-shaped structure 126 is reduced, and falling of the non-stick coating at the arc-shaped structure is reduced.

Wherein the average thickness of the sidewall segments on the upper side is thinner, i.e., the sidewall 124 thickness of the container body 12 is smaller as it goes above. And the projected area of the non-stick coating 18 on the first sidewall segment with the higher position is smaller than the projected area of the non-stick coating 18 on the second sidewall segment with the lower position, so that the thickness of the sidewall 124 and the area of the non-stick coating 18 are adapted, that is, the thickness of the sidewall 124 is thinner, and the corresponding non-stick coating 18 has a smaller ratio. This arrangement helps to increase the strength of the container body 12 on the one hand, on the other hand, to increase the thermal conductivity of the container body 12 on the side walls 124, and on the other hand, to promote heat transfer at thicker thicknesses, to reduce heat concentrations, to reduce the risk of the non-stick coating 18 falling off, and finally, to promote the dispersion of hot air within the container body 12, to improve the uniformity of temperature within the container body 12.

The first sidewall section and the second sidewall section are two sections of the sidewall that are arbitrarily divided in the height direction, for example, the first sidewall section and the second sidewall section may be divided by 1/2 of the sidewall height. Of course, the division may be made by 1/3.

In the above embodiment, as shown in fig. 2, the non-stick coating 18 is lower than or flush with the surface of the notch of the groove 14, that is, the thickness of the non-stick coating 18 is less than or equal to the depth of the groove 14, that is, the non-stick coating 18 does not protrude from the surface of the notch of the groove 14, so that the non-stick coating 18 can be received in the groove 14, and when the cooking appliance is used, the non-stick coating 18 can be protected by the protrusions 16 between the grooves 14, so that scratches and abrasion of the non-stick coating 18 are not easy to occur, that is, the non-stick coating 18 is not easy to be damaged, so that the non-stick performance of the container such as an inner pot can be ensured, and the service life of the container assembly 1 is improved.

In the above embodiment, as shown in fig. 2, the non-stick coating 18 is provided on all of the groove bottom walls of the groove 14 and all of the groove side walls of the groove 14, and the projected area of the non-stick coating 18 in the groove 14 is equal to the sum of the area of the non-stick coating 18 on the groove bottom walls and the area of the non-stick coating 18 on the groove side walls.

In the above embodiment, the protrusions 16 and the grooves 14 are formed from the container body 12 by an etching process.

In this embodiment, the protrusion 16 and the groove 14 are engraved by the etching process on the container body 12, the groove 14 and the protrusion 16 are integrated with the container body 12, the groove 14, the protrusion 16 and the container body 12 are integrally formed, the integrally formed container body 12 has a longer service life, is not easily damaged, and improves the reliability of use.

This enriches the shape design of the protrusions 16, and gives a beautiful appearance while satisfying the performance.

Further, the non-stick coating 18 on the bottom wall 122 of the container body 12 is integrally connected to each other, or the non-stick coating 18 on the bottom wall 122 of the container body 12 is divided into a plurality of pieces, the non-stick coating 18 on the side wall 124 of the container body 12 is integrally connected to each other, or the non-stick coating 18 on the side wall 124 of the container body 12 is divided into a plurality of pieces. I.e., the grooves 14 of the container body 12 can be communicated with each other so that the non-stick coating layers 18 are integrally connected with each other, and the grooves 14 of the container body 12 can be independently opened, and at this time, the non-stick coating layers 18 are separated into a plurality of pieces.

In the above-described embodiments, the container body 12 is made of one or more materials of aluminum, aluminum alloy, stainless steel, titanium alloy, iron. Of course, the container body 12 may be made of other materials.

Example two

In this embodiment, as shown in fig. 3, the concave-convex pattern 19 is composed of a plurality of basic cells, and each basic cell includes a cell protrusion and a groove surrounded by the cell protrusion. For example, the cells may be of regular polygonal configuration. In order to enable communication between adjacent cells, openings may be provided in the sidewalls 124 of the protrusions to render the protrusions non-closed, with open structures.

Further, the area enclosed by the cell protrusions decreases from bottom to top in the height direction of the container body 12. Further, in the unit cell, the projected area of the protrusions on the inner wall of the container body 12 is d, and the ratio of the sum of d to S1 on the inner wall is greater than the ratio of the sum of d to S2 on the inner bottom wall. Further, in the height direction of the container body 12, the value of d gradually increases from bottom to top,

in this embodiment, the area enclosed by the protrusions of the cells is reduced from bottom to top, that is, the area of the grooves in the cells is smaller upwards, that is, the whole cells are smaller upwards, so that when the cells are sequentially connected and arranged, the arrangement density of the cells is increased more densely, that is, the number of the cells is increased more upwards, and in this way, the area of the protrusions 16 in the concave-convex lines 19 is increased more upwards, so that the heat transfer area of the upper end of the container body 12 can be increased, and the heat transfer performance is balanced. At the same time, the area ratio of the protrusions 16 on the side walls 124 is larger than the area ratio of the protrusions 16 on the bottom wall 122, so that the accumulation of heat on the lower part can be reduced, the risk of falling off the non-stick coating 18 is reduced, and the heat conduction efficiency of the side walls 124 can be increased, so that the heat conduction of the container body 12 is more balanced.

Further, on the side wall surface of the container body 12, the projected area of the protrusions of the unit cells is increased from bottom to top, which is equivalent to that in the unit area, the protruding area of the upper end of the side wall 124 is larger than that of the lower end of the side wall 124, so that the advantage of the arrangement is that the contact area between the protrusions 16 of the upper end of the container and food is effectively increased, and meanwhile, the coating area is small, because the protruding area is large, the area of the grooves 14 is reduced, the coating area is relatively reduced, and the heat conduction effect is good because the coating area is small. This kind of setting makes the heat conduction effect of container body 12 upper portion greater than the heat conduction effect of lower part, also can understand that the protruding area of upper portion is big, consequently, the radiating area is big, the non-stick coating 18 area of upper portion is little, consequently, the heat conduction effect is better, can compensate the influence that the heat transfer is slower in lateral wall 124 upper portion from two aspects like this, it is more even that the upper portion and the lower part that make food can be heated, thereby can improve the scratch resistance of container body 12 upper portion, reduce the destruction of shovel spoon etc. to non-stick coating 18, the effect that makes food cook out can be better.

Further, as shown in fig. 4, the circumferential width of the grooves of the cells is a first width t1, the first width t1 decreases from bottom to top along the height direction of the container body 12, and/or the first width t1 of the cells on the side walls 124 is smaller than the first width t1 of the cells on the bottom wall 122. Further, the grooves of the cells have a longitudinal width of a second width t2, the second width t2 increasing from bottom to top along the height of the container body 12, and/or the second width t2 of the cells on the side walls 124 is greater than the second width t2 of the cells on the bottom wall 122.

In this embodiment, the circumferential width of the grooves in the cells, i.e., the circumferential width of the grooves in the side walls 124, decreases from bottom to top, i.e., the more the cells are above the container body 12, and the first width t1 of the cells in the side walls 124 is smaller than the first width t1 of the cells in the bottom wall 122, i.e., the cells in the side walls 124 are more slender than the cells in the bottom wall 122, thereby increasing the arrangement density of the cells in the side walls 124 and the arrangement density of the cells above the side walls 124, thereby improving the thermal conductivity of the side walls 124, and the more the side walls 124 are above, thereby improving the thermal conductivity of the side walls 124 as a whole, and improving the thermal conductivity of the container body 12. In addition, this arrangement, because of the better thermal conductivity over the sidewall 124, helps to reduce heat build-up at the lower portion, reduces the risk of lower coating falling off, and thus improves non-stick performance. In addition, since the convex area of the upper portion is relatively large in proportion, the protection of the non-stick coating 18 can be enhanced, and the scratch resistance of the upper portion of the container to the food material can be improved. And the non-stick coating 18 above the side wall 124 can be divided into a finer structure by the arrangement, so that the non-stick coating 18 above the side wall 124 can be firmly attached to the container wall, and the peeling risk of the coating on the upper part of the container is reduced. The arrangement can also reduce the stress concentration phenomenon of the container body 12 at the contact position of the food material and the container body 12, and improve the corrosion resistance.

In addition, when the container body 12 is used in an air fryer, that is, when the container body 12 is used in an air frying environment, heat can be promoted to flow to the lower part of the container, heating of food materials can be promoted, resistance of the heat to the upper part of the container can be improved, heat dispersion can be improved, and uniformity of flow of hot air in a container cavity can be improved, so that uniformity of heating of the food materials can be improved.

Further, the ratio of the first width t1 of the cells on the bottom wall 122 to the first width t1 of the cells on the side wall 124 is 1.2 or more and 1.5 or less. That is, the widths of the pairs of cells on the bottom wall 122 and the side walls 124 should not differ too much, and the range is such that the ratio of the widths of the two is relatively moderate, thereby facilitating the processing.

In any of the above embodiments, the container body 12 includes a bottom wall 122 and a side wall 124, the bottom wall 122 and the side wall 124 are connected by an arc structure 126, the projected area of the non-stick coating 18 in the cell on the inner wall of the container body 12 is c, the rate of change of c on the side wall 124 compared to c on the arc structure 126 is a first rate of change, and the rate of change of c on the arc structure 126 compared to c on the bottom wall 122 is a second rate of change, the first rate of change being greater than the second rate of change; and/or the projected area of the protrusions on the inner wall of the container body 12 is d, the rate of change of d on the side wall 124 compared to d on the arcuate structure 126 is a third rate of change, the rate of change of d on the arcuate structure 126 compared to d on the bottom wall 122 is a fourth rate of change, and the third rate of change is greater than the fourth rate of change.

In this embodiment, the projected area of the non-stick coating 18 on the inner wall of the container body 12 within a cell is varied, specifically, the projected area of the non-stick coating 18 on the bottom wall 122 is greater on the same cell than on the inner wall of the arcuate structure 126, and is greater on the inner wall of the arcuate structure 126 than on the side wall 124. However, the area of the non-stick coating 18 should not be too changed, and it is preferable that the rate of change of the area of the non-stick coating 18 in the cells is smaller when the bottom wall 122 transitions to the arcuate structure 126 than when the arcuate structure 126 transitions to the side wall 124, and at the same time, the projected area of the protrusions in the cells on the inner wall of the container body 12 is d, and the rate of change of the projected area d is greater when the arcuate structure 126 transitions to the side wall 124 than when the bottom wall 122 transitions to the arcuate structure 126. This arrangement allows for better distribution of the non-stick coating 18, which may increase the thermal conductivity of the sidewall 124 to more evenly balance the thermal conductivity of the container body 12. Specifically, the greater rate of change at the side walls 124 may facilitate rapid transfer of energy to the side walls 124 at the arch structures 126 and at the bottom wall 122, reduce the build-up of heat at the arch structures 126 and at the bottom wall 122, reduce the risk of peeling of the non-stick coating, and increase the non-stick properties at the arch structures 126 and at the bottom wall 122. In addition, the rate of change of arc structure 126 department is less, on the one hand can improve the shaping ability of product, on the other hand, avoids the heat to appear when heat is transmitted to lateral wall 124 from the bottom, has improved the corrosion resistance of arc structure 126 department. Meanwhile, through the combined action of the larger change rate at the side wall 124 and the smaller change rate at the arc-shaped structure 126, the corrosion resistance of the bottom wall 122 and the arc-shaped structure 126 can be improved, and the heat transfer at the side wall 124 is promoted; in addition, the flow of heat to the lower part of the container can be promoted, the heating of food materials is promoted, the resistance of the heat to the upper part of the container is improved, the heat dispersion is improved, the uniformity of the flow of hot air in the container cavity is improved, and the uniformity of the heating of the food materials is improved.

Further, the projected area of the non-stick coating 18 in the cell on the inner wall of the container body 12 is c1, the projected area of the non-stick coating 18 in the cell on the inner wall of the container body 12 is c2, the projected area of the non-stick coating 18 in the cell on the inner wall of the container body 12 is c3, and the projected area of the non-stick coating 18 in the cell on the inner wall of the container body 12 is c3, wherein |c1-c2|/c2> |c2-c3|/c3, on the side wall 124 higher than 1/2 of the height of the container body 12, on the area of the arc structure 126 lower than 1/2 of the arc structure 126. This arrangement promotes the protection of the upper portion of the container against the non-stick coating 18, improves the scratch resistance of the container body 12, improves the thermal transition in the connection area between the bottom wall 122 and the arcuate structure 126, reduces heat build-up, and improves corrosion resistance. Meanwhile, the heat of the upper part of the container can be promoted to flow to the lower part of the container, the heating of food materials is promoted, the resistance of the heat to the upper part of the container is improved, the heat dispersion is improved, the uniformity of the flow of hot air in the cavity of the container is improved, and the uniformity of the heating of the food materials is improved.

Further, the projected area of the protrusions on the inner wall of the container body 12 in the cells is d1, the projected area of the protrusions on the inner wall of the container body 12 in the cells is d2, the projected area of the protrusions on the bottom wall 122 of the container body 12 in the cells is d3, and the projected area of the protrusions on the inner wall of the container body 12 in the cells is d1-d 2/d 2> |d2-d3|/d3.

In any of the above embodiments, the concave-convex pattern 19 is formed by combining a plurality of cells, and the cells are uniformly distributed on the inner side wall and the inner bottom wall. I.e. the relief 19 is made up of regular cells.

In any of the above embodiments, the arrangement density of the cells on the side wall surface of the container body 12 is greater than the arrangement density of the cells on the inner bottom wall. This arrangement allows more cells to be formed on the side wall 124, and therefore allows the side wall 124 to provide better thermal conductivity, which balances the overall thermal conductivity of the container body 12.

In any of the above embodiments, the arrangement density of the unit cells increases from bottom to top on the side wall surface of the container body 12 along the height direction of the container body 12. This arrangement allows more cells on the side walls 124 to be located above, and therefore, allows the thermal conduction effect of the upper side of the side walls 124 to be better, thereby balancing the overall thermal conduction effect of the container body 12.

In any of the above embodiments, the height of the protrusions in the thickness direction of the side walls 124 of the container body 12 decreases from bottom to top in the height direction of the container body 12.

In this embodiment, the height of the protrusions in the thickness direction of the side wall 124 of the container body 12, that is, the dimension of the protrusions 16 protruding from the inner side wall, is smaller as it goes upward, that is, the protrusion 16 goes upward, the protrusion effect is less noticeable. This enables the total area of the projections 16 to be reduced from bottom to top in the height direction of the container body 12, so that the heat conductive property above the container body 12 can be improved.

In this embodiment, to increase the area of the non-stick coating 18, the non-stick coating 18 is coated on both the groove side walls and the groove bottom wall of the groove 14, whereby the non-stick performance of the container body 12 can be ensured. While in the cells the projected area of the non-stick coating 18 is the sum of the areas comprising the groove side walls and the groove bottom wall.

In the above embodiments, the projections 16 or the recesses 14 may be provided on the inner bottom wall of the container body 12, on the inner side wall, or on both the inner bottom wall and the inner side wall of the container body 12. In one embodiment, however, the projections 16 and recesses 14 are uniformly distributed. Through the arrangement mode that the protrusions 16 or the grooves 14 are uniformly distributed on the inner surface of the container body 12, in the process that food is contacted with the inner surface of the container body 12, the food can be uniformly contacted, so that the food can be heated more uniformly, and in the stir-frying process, the contact of the tip part of an appliance for stirring the food with the non-stick coating 18 on the surface of the container body 12 caused by uneven distribution can be avoided, the unnecessary abrasion and scratch of the non-stick coating 18 are caused, the service life of the container assembly 1 is better prolonged, and the fact that the non-stick coating 18 on part of the surface of the container body 12 cannot be protected due to uneven distribution is avoided, so that the non-stick coating 18 is scratched and abraded in the cooking process.

Example III

In the third embodiment, the difference is that the thickness of the side wall 124 of the container body 12 becomes thinner from bottom to top in the height direction. While other configurations of the container body are consistent with either the first or second embodiments.

In this embodiment, when the food is cooked, the heating area is concentrated at the bottom of the container body 12, and because the coating area at the bottom of the container body 12 is relatively large, heat can be blocked to a certain extent in the process of transferring the heat to the food, and the heat transfer along the direction of the side wall 124 is relatively low, so that the food is unevenly heated. That is, the arrangement improves the uniformity of heating of the container.

In the above embodiment, the outer wall surface of the container body 12 is provided with the mating texture, and the grooves and the protrusions of the mating texture are arranged in one-to-one correspondence with the grooves 14 and the protrusions 16 of the concave-convex texture 19.

In any of the above embodiments, the wall thickness of the container body 12 is 0.5mm or more and 1.5mm or less.

In this embodiment, when the wall thickness of the container body 12 is set to be between 0.5 and 1.5mm, after the concave-convex pattern 19 is etched on the inner side wall of the container body 12 through the etching process in the manufacturing process of the container body 12, the concave-convex pattern 19 on the outer side of the container body 12 is naturally formed due to stress through stretching molding, and no additional setting is needed, so that the process flow is reduced, and the cost is saved.
