Due to the adoption of the technical scheme, the beneficial effects obtained by the application are as follows:

1. in the cooking process, the heat of the liner corresponding to the heating device area is concentrated most, so that the problems of sticking and burning are most likely to occur; the heat quantity extending to the side wall part of the inner container is relatively little, and the heat quantity is smaller than that of the inner container positioned in the area corresponding to the heating device, so that the anti-sticking part is arranged in the area corresponding to the heating device, and the non-sticking effect of the easily-sticking pot area can be effectively realized. Through setting up recess or arch at antiseized portion for have the space of water storage and water absorption on the inner wall of inner bag, thereby guaranteed to form evenly distributed's water film on the inner wall of inner bag, the water film has blocked the direct contact of the inner bag wall of rice grain in the inner bag and inner bag, thereby realized antiseized. In addition, because the heat conduction performance of water is greater than the heat conduction performance of rice grains, and the heat conduction performance of water can also be gradually enhanced along with the rise of temperature, the existence of water film can realize quick even heat conduction for rice grains can not produce the problem of being burnt and yellow because of pressing close to inner surface of inner bag.

The mark scale area is used for providing an indication for a user, and the rice water quantity is reasonably added before cooking. The mark scale area is arranged in the smooth part area, so that the mark scale area is easy to set and clear, and the user can conveniently recognize and observe; because the anti-sticking part is independently distributed with grooves or bulges relative to the inner wall of the liner, if the mark scale area is arranged in the area, the user cannot see clearly, and the anti-sticking part is not easy to arrange.

4. The surface of the anti-sticking part and the smooth part is a hydrophilic metal layer. The surface is the hydrophilic metal layer, so that the whole inner surface of the corresponding inner container is always kept with a water film, the inner surfaces of the rice and the inner container are always kept with the water film in the rice cooking process, and particularly in the later stage of rice cooking, such as the full cooking stage, the heat preservation stage and a period of time after the cooking is finished, the bottom heating device still has residual heat, and at the moment, the water in the cooking utensil is less, and due to the hydrophilic characteristic of the anti-sticking part, the water in the rice upper layer and between rice grains can be adsorbed, so that the inner surface of the inner container is always kept with the water film, and the non-sticking performance in the whole cooking process is ensured.

Through setting up recess 311 or arch at antiseized portion 310 for have the space of water storage and water absorption on the inner wall of inner bag 300, thereby guaranteed to form evenly distributed's water film on the inner wall of inner bag, the water film has blocked the direct contact of the inner bag wall of rice grain and inner bag in the inner bag 300, thereby realizes antiseized. In addition, because the heat conduction performance of water is greater than the heat conduction performance of rice grains, and the heat conduction performance of water can also be gradually enhanced along with the rise of temperature, the existence of water film can realize quick even heat conduction for rice grains can not produce the problem of being burnt and yellow because of pressing close to inner surface of inner bag.

A demarcation portion 330 is provided between the anti-sticking portion 310 and the smooth portion 320, and the demarcation portion 330 cuts at least part of the groove 311 or the protrusion on the tip of the anti-sticking portion 310 to form a circumferentially flat annular support portion. The water on the side wall of the inner container 300 is supported, namely, the water on the wall surface of the smooth part 320 is supported, so that the problem that the rice at the bottom is excessively wet due to the fact that the water flows to the anti-sticking part 310 at the bottom of the inner container is avoided; in addition, the annular supporting portion is arranged to make the overall thickness of the anti-sticking portion 310 thicker than that of the smooth portion 320, so that heat of the smooth portion can be quickly transferred to food and water in the smooth portion, and the problem that the food and water are overheated and stuck to a pot is reduced.

As a preferred embodiment, at least part of the height of the annular supporting portion is higher than the smooth portion 320. Further, the supporting force of the water on the side wall of the inner container can be further ensured, and the problem that the rice at the bottom is excessively wet due to the fact that the water completely flows to the anti-sticking part 310 at the bottom is avoided.

It should be noted that, the shape and arrangement of the grooves 311 or the protrusions are not limited, and may be circular, square, polygonal, or irregular; the arrangement mode can be distributed on the inner surface of the liner 300 in an array or annular mode, and other distribution modes can be adopted, and the arrangement mode can be specifically determined according to the shape of the liner 300, the matching of the manufacturing process and the like.

It should be noted that, the boundary portion cutting the top end of the anti-sticking portion at least partially forms a groove or a protrusion forms a circumferentially flat annular supporting portion, which means that the annular supporting portion cuts the protrusion or groove, that is, the annular supporting portion makes the top of the groove or protrusion not be a complete protrusion or groove. The stated cutting may be a cutting, polishing process, or may be formed by other processes, such as a ring-shaped support formed by rolling; or may be an etched annular support; or an engraved annular support.

A connecting part 312 is arranged between the adjacent grooves 311, so that each groove 311 is independently arranged; and the diameter d1 of the groove 311 is larger than the width L of the connection portion 312. Therefore, the water film area formed by the grooves 311 is larger than the area formed by the connecting portions 312, so that the non-sticking effect is improved, and as the connecting portions 312 are made of metal, the surface of the connecting portions 312 also forms a water film structure due to the hydrophilic performance of the metal, so that the water film on the inner surface of the whole anti-sticking portion 310 in the cooking process can be ensured, and the integral non-sticking performance of the anti-sticking portion is improved.

It should be noted that, the anti-sticking part of the present utility model may include the following forms, 1, after forming grooves or protrusions on the inner surface of the liner, connecting parts are formed on the inner surfaces connected by adjacent grooves or protrusions; 2. the connecting parts between the adjacent grooves or the adjacent bulges are processed into fine lines to form the connecting parts of the utility model; 3. the connecting parts between the adjacent grooves are processed to be lower or higher than the inner surface of the original liner, so as to form the connecting parts of the utility model. Of course, the above description does not represent a limiting structure for the connection of the present utility model.

As a further optimized embodiment, the surfaces of the anti-adhesion part 310 and the smooth part 320 are hydrophilic metal layers. Due to the hydrophilic property of the metal, the surface of the anti-sticking portion 310 and the smooth portion 320 always maintains a water film during cooking, so as to improve the non-sticking property of the whole inner container.

As shown in fig. 4, the inner surface of the inner container 300 is further provided with a protective metal layer 360. The inner surface of the inner container 300 is provided with a protective metal layer 360, so that the anti-discoloration and scratch-proof performances of the inner surface of the inner container 300 are further improved, and preferably, the protective metal layer 360 can be a chromium metal layer or a titanium metal layer.
