Example two

In this embodiment, it is different from embodiment 1 in that, as shown in fig. 1 and 2, the first embossment line is formed by the first grooves 14 and the first protrusions 16, and a plurality of first grooves 14 and a plurality of first protrusions 16 are uniformly distributed on the inner side wall region higher than or flush with the first position. The embossed pattern includes a second embossed pattern (not shown in the figure) provided on an inner side wall region lower than the first position, the second embossed pattern being formed by a second groove and a second protrusion. The embossing patterns include a third embossing pattern (not shown) provided on the inner bottom wall of the container body 12, the third embossing pattern being formed by third grooves and third projections.

In this embodiment, the protrusion includes a first protrusion 16 for enclosing a first groove 14 with the inner sidewall of the container body 12, that is, the protrusion above the first position is the first protrusion 16, and the first protrusion 16 and the first groove 14 form a first concave-convex pattern. Meanwhile, a second protrusion is arranged on the inner side wall area lower than the first position, a second groove is formed by the second protrusion and the inner side wall of the container body 12 in a surrounding mode, and second concave-convex grains are formed by the second groove and the second protrusion. Further, be provided with the unsmooth line of third on the diapire of container body 12, just also the unsmooth line of bottom to this can form the protection through the unsmooth line of bottom to the non-stick coating 18 of bottom. This kind of scheme can form the protection to the non-stick coating 18 of the position that corresponds through first unsmooth line, the unsmooth line of second and third unsmooth line, avoids non-stick coating 18 to be scraped badly. This kind of setting, at the in-process of culinary art food, the effectual most advanced position that prevents the shovel directly contacts with non-stick coating 18 and carries out fish tail or drop to non-stick coating 18, and then just can ensure the non-stick performance of containers such as interior pot, has improved the life of container subassembly 1.

In the above embodiment, in the wall thickness direction of the container body 12, the thickness of the first concave-convex pattern is smaller than the thickness of the second concave-convex pattern, and smaller than the thickness of the third concave-convex pattern.

In this embodiment, the height of the first projection 16 is smaller than the height of the second projection and smaller than the height of the third projection in the wall thickness direction of the container body 12. Wherein, the height of the first projection 16 refers to the dimension of the first projection 16 in the direction perpendicular to the thickness of the sidewall of the container body 12. The height of the third projection means the dimension of the first projection 16 in the height direction of the container body 12. I.e. the height of the first bulges 16 above the first position of the food steamer or the like, i.e. the height of the bulges at the positions corresponding to the food steamer or the like, is smaller than the height of the third bulges at the bottom wall and smaller than the height of the second bulges below the first position. Therefore, the distance between the first bulge 16 and the placing parts such as the food steamer can be reduced, the abrasion of the placing parts such as the food steamer on the first bulge 16 on the side wall is reduced, and the protection of the non-stick coating is improved. On the other hand, in the case of a food steamer having holes in the side walls, the obstruction of the flow of water between the food steamer and the inner pot or the like 12 can be reduced.

Further, the third grooves are evenly distributed on the inner bottom wall of the container body 12.

In this embodiment, through this kind of mode of setting of the even distribution of third recess at the interior diapire of container body 12, in the in-process of food and the contact of container body 12 interior diapire, can the uniform contact, make food can be heated more evenly, and set up like this and can also avoid food in the in-process of turning over the stir-fry, the utensil tip position of turning over food is because the non-stick coating 18 contact with the surface of container body 12 that the distribution inequality leads to, cause unnecessary wearing and tearing to non-stick coating 18, the better life who has improved container subassembly 1, avoid because the distribution is uneven, make the non-stick coating 18 of the partial surface of container body 12 can not protected, lead to taking place fish tail and wearing and tearing at the non-stick coating 18 of culinary art in-process.

In the above embodiment, the area ratio of the projection on the inner side wall surface of the container body 12 increases from bottom to top in the height direction of the container body 12.

In this embodiment, the sum of the total areas of the protrusions in the unit area from bottom to top is increased on the side wall surface of the container body 12, which is equivalent to the sum of the areas of the protrusions at the upper end of the side wall larger than the area of the protrusions at the lower end of the side wall in the unit area, so that the advantage of this arrangement is that the contact area between the protrusions at the upper end of the container and food is effectively increased, and the area of the non-stick coating is small, because the area of the protrusions is large, the area of the grooves is reduced, and therefore the area of the non-stick coating is relatively reduced, and the heat conduction effect is good when the area of the non-stick coating is small. This kind of setting makes the heat conduction effect on container body 12 upper portion be greater than the heat conduction effect of lower part, also can understand that the protruding area on upper portion is big, and consequently, heat radiating area is big, and 18 areas on non-stick coating on upper portion are little, and consequently, heat conduction effect is better, can compensate the influence that lateral wall upper portion transmission heat brought more slowly like this from two sides, makes the upper portion and the lower part of food more even some can be heated, makes the effect that food was cooked out can be better.

Simultaneously, when cooking food, the heating region is all concentrated and is set up in the bottom of container body 12, because the non-stick coating area ratio of container body 12 bottom is great for the heat can receive certain hindrance at the in-process that transmits for food, and the heat transfer along the lateral wall direction is lower, makes being heated of food inhomogeneous. And this application sets the lateral wall of the container body 12 to the form of following the thinning from bottom to top of direction of height for the heat can be faster transmits the upper end for the lateral wall from the lower extreme of lateral wall, and the heat can be faster like this transmits food, makes being heated of food can be more even, and the food taste of cooking out can be better. Meanwhile, the thickness of the side wall on the upper side is thinner, and the protruding area of the upper part is larger, so that the strength of the side wall on the upper part can be improved, the thickness of the side wall on the lower part is thicker, and the protruding area of the lower part is smaller, so that the concentration of heat on the side wall on the lower part can be further reduced, the heat can be more quickly transmitted upwards, and through the reasonable arrangement of the thickness of the side wall and the cooperative match of the protruding areas, the integral strength of the side wall can be ensured, meanwhile, the overheating phenomenon of the bottom can be reduced, the cooking effect can be improved, and the heating uniformity of the container can be improved.

Meanwhile, the distance between the protrusions on the bottom wall is smaller than that between the protrusions on the side wall, namely, the protrusions on the bottom are arranged densely, and the protrusions on the side wall are arranged sparsely.

Further, the pitch of the plurality of first projections 16 in the height direction of the container body 12 gradually increases from bottom to top. That is, the farther to the upper side, the larger the pitch of the projections, that is, the farther to the upper side, the more sparsely the projections are arranged in the height direction.

In the above-described embodiment, the arrangement density of the projections on the side wall of the container body 12 in the circumferential direction of the container body 12 is greater than the arrangement density of the projections on the bottom wall of the container body 12. Further, the arrangement density of the first projections 16 in the circumferential direction of the container body 12 is greater than the arrangement density of the second projections in the circumferential direction, and is also greater than the arrangement density of the third projections on the inner bottom wall of the container body 12. That is, from the bottom to the top, the protrusions are more and more dense, that is, the distance between the protrusions is smaller and smaller. At the same time, the circumferential spacing on the side wall is also smaller than the spacing of the projections on the bottom wall. This kind of setting can improve the homogeneity that steam flows along direction of height, improves the effect to placing an even heating such as food steamer, and on the other hand helps the even heating to container body 12.

Further, along the height direction of the container body 12, the transverse distance between two adjacent protrusions in the same circumferential direction gradually decreases from bottom to top, or the transverse distance between two adjacent first protrusions 16 in the same circumferential direction is smaller than the transverse distance between two adjacent second protrusions in the same circumferential direction; the lateral spacing between two adjacent projections in the same circumferential direction is smaller than the spacing between the projections on the bottom wall of the container body 12. This kind of setting is favorable to the homodisperse of steam, to eating the homogeneity of material heating in the food steamer, and to the porose food steamer of side, can improve the homogeneity that rivers flow, improve the speed that rivers flow, make hydroenergy enough flow downwards in time, reduce piling up of water between the food steamer and the container body, improve the oil strain in the culinary art or the effect of low sugar.

Further, the arrangement density of the first projections 16 in the circumferential direction of the container body 12 is gradually reduced from bottom to top in the height direction of the container body 12. That is, the first projection 16 is gradually reduced in the height direction of the container body 12.

In any of the above embodiments, the second embossment extends upwardly from the bottom of the interior sidewall of the container body 12 to a first position, and the first embossment extends upwardly from the first position by a predetermined height.

In this embodiment, the projections of the inner side walls of the container body 12 extend upward from the bottom of the inner side walls of the container body 12 to a position higher than the lowest position of the basket in the container body 12. I.e., the non-stick coating 18 is disposed upwardly from the bottom and must exceed the lowest position of the basket in the container body 12.

Further, first raised grain route is upwards extended to the opening of container body 12 by first position, or first raised grain distance opening is provided with the default distance that is greater than 5 mm. In the practical process, the distance between the highest point of the concave-convex structure and the highest point of the end surface of the container body is different according to different sealing structures. If the cooking utensil does not need to be sealed, all areas of the inner wall surface of the container body can be provided with concave-convex structures; if the cooking utensil is in an end face sealing structure, namely the sealing element is only contacted with the end face of the container, the end face area of the container body is not provided with a concave-convex structure; if the cooking utensil is sealed for the side, then the partial region of terminal surface and container internal wall face does not set up concave-convex structure, and the distance of concave-convex structure peak and container body terminal surface peak is greater than 5mm to guarantee that sealing member and container fully contact, improve sealed effect, avoid steam to reveal, so that can reduce the thermal loss of container mouth department, promote the heat to eat the material transmission, with this heating efficiency who has just improved the container body. And meanwhile, the concave-convex structure is higher than the lowest position of the steamer, so that the protection of the coating on the upper part of the container body and the heating uniformity of the container body at the corresponding part of the steamer are ensured. In the above described embodiment, all of the well bottom walls and all of the well side walls of the wells are provided with a non-stick coating 18.
