Abstract

The invention provides a container assembly and heating equipment, wherein the container assembly comprises a container body, non-stick coating layers are arranged in grooves, projection areas of the non-stick coating layers on the inner side walls are a, the areas of the inner side walls are S1, projection areas of the non-stick coating layers on the inner bottom walls are b, and the areas of the inner bottom walls of the container body are S2, and a/S1 is less than or equal to b/S2. According to the scheme, the non-stick coating can be protected through the protrusions between the grooves, so that scratch and abrasion of the non-stick coating are not easy to occur. The heat conduction performance of the non-stick coating is poorer than that of the container material, so that the projected area of the non-stick coating on the inner side wall is smaller than that of the non-stick coating on the inner bottom wall, the heat conduction performance 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.

Description

Container assembly and heating apparatus Technical Field The invention relates to the field of cooking appliances, in particular to a container assembly and heating equipment. Background In the prior art, no matter the cooking utensil in the market is heating pipe heating, hot plate heating or electromagnetic heating, the heat of container bottom is comparatively concentrated, and the food material that keeps away from the bottom is heated less, causes the food to heat unevenly from top to bottom. And food is heated unevenly, in the culinary art in-process, the container bottom takes place the food easily and glues the end, paste the end, causes the yellowing problem of container bottom even, has influenced the experience sense in the user's the use greatly. 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 purpose, the technical scheme of the invention provides a container assembly, which comprises a container body, a non-stick coating and a non-stick coating, wherein the container body comprises an inner side wall and an inner bottom wall, concave-convex grains are formed on the inner side wall and the inner bottom wall, the concave-convex grains comprise protrusions and grooves, the grooves are formed by surrounding the protrusions and the inner wall of the container body, the non-stick coating is arranged in the grooves, 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, the area of the inner bottom wall of the container body is S2, and 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.
