Hereinafter, specific embodiments of the present invention will be described in more detail with reference to the accompanying drawings, which illustrate representative embodiments of the present invention and do not limit the present invention.

Generally, a cooking appliance such as an electric rice cooker includes a pot body and a lid. The pot body is substantially in a rounded rectangular parallelepiped shape and has a cylindrical inner pot accommodating portion. The inner pot can be fixedly arranged at the inner pot containing part, or can be freely put into the inner pot containing part or taken out from the inner pot containing part, so that the inner pot can be conveniently cleaned. The inner pot is generally made of a metal material and has a circular opening on an upper surface for containing a material to be heated, such as rice, soup, etc. The cooker body comprises a heating device for heating the inner pot so as to heat the inner pot. It can be understood that according to the utility model discloses a cooking utensil can be electric rice cooker, electric pressure cooker or other cooking utensil, and cooking utensil except having the function of cooking rice, can also have various functions such as cooking congee.

The lid body has a shape substantially corresponding to the pot body, substantially in the shape of a rectangular parallelepiped with a rounded corner, is pivotally connected to the pot body through a pivot shaft, and can be freely pivoted about the pivot shaft between a lid-closed position and an open position with respect to the pot body, so as to facilitate the lid-closed and opening of the pot body. When the cover body is covered on the cooker body, the cover body covers the inner pot, and a cooking space is formed between the cover body and the inner pot. The lid body also usually has a sealing ring, which may be made of e.g. rubber material, arranged between the lid body and the inner pot for sealing the cooking space when the lid body is in the closed position.

In order to prevent the inner pot from sticking to the pot, as shown in fig. 1 and 2, the inner pot 10 according to a preferred embodiment of the present invention is made of a non-metallic material. The inner pot 10 can be formed with a plurality of anti-sticking portions 12 spaced apart from each other, and specifically, the inner pot 10 includes an inner pot body 11, and the anti-sticking portions 12 are disposed on the inner pot body 11 at intervals and are molded as a single piece with the inner pot body 11. In this embodiment, the inner pot 10 may have a desired anti-sticking property by the plurality of anti-sticking portions 12, and the configuration of the anti-sticking portions 12 may not be changed, so that the non-sticking property of the inner pot 10 can be always maintained at a desired level without being lowered with the long-term use of the inner pot 10. The inner surface of the inner pan 10 is not provided with coatings such as non-stick coatings or protective coatings, so that the phenomenon that the coatings are mixed into food after falling off and are eaten by consumers by mistake is avoided, and the health of the human body is ensured.

The anti-sticking portion 12 may include at least one of a protrusion protruding from the inner surface of the inner pan 10 and a recess recessed from the inner surface. The arrangement of the convex parts and the concave parts can increase the heat transfer area of the inner surface and improve the heat transfer efficiency. In the illustrated embodiment, fig. 2 only schematically illustrates the shape of the anti-adhesion portion 12 as viewed in plan, and does not illustrate that the anti-adhesion portion 12 is a protrusion and/or a depression. Alternatively, the anti-adhesion portion 12 is a projection or a depression, which may facilitate manufacturing to form the anti-adhesion portion 12. Preferably, the anti-sticking portion 12 is a projection to facilitate cleaning.

In one embodiment, the projections may extend inwardly from the inner surface of the inner pot body 11, with the outer surface of the inner pot body 11 being smooth. The recess may be outwardly recessed from the inner surface of the inner pot body 11, and the outer surface of the inner pot body 11 is also smooth. In this embodiment, both the protrusions and the depressions are formed only on the inner surface of the inner pot 10, thereby facilitating manufacturing.

It should be noted that directional terms used herein to describe various parts, components, etc. of the inner pan 10 assembly, such as "upper", "lower", "above", "below", "up", "down", etc., are relative to the inner pan 10 in a horizontal position. The directional terms "inner" and "outer" if not otherwise defined, e.g., with respect to the generally cylindrical inner pot 10, it is understood that, e.g., "inwardly" refers to a direction toward the center of the inner pot 10 and "outwardly" refers to a direction away from the center of the inner pot 10.

In another embodiment, the protrusion may protrude from the outer surface toward the inner surface of the inner pot body 11. The recess may be recessed from the inner surface of the inner pot body 11 toward the outer surface of the inner pot body 11. That is, the convex and concave portions may be formed by changing the overall shape of the inner pot body 11. In this embodiment, the anti-sticking portion 12 can be formed by the integral deformation for the thin inner pot 10.

The inner pot 10 may be made of a glass material or a ceramic material. Optionally, the inner pan 10 has a thickness of 3mm to 6mm, e.g., 3mm, 4mm, 5mm, 6 mm. The dimension L1 of the anti-sticking portion 12 in the thickness direction of the inner pot 10 may be 3mm to 15mm, for example, 3mm, 6mm, 9mm, 12mm, 15 mm. The distance D1 between the adjacent anti-sticking portions 12 is 3mm to 10mm, for example, 3mm, 5mm, 8mm, 10 mm. The anti-adhesion portion 12 may have a smoothly transitioning arcuate surface, and the shape of the anti-adhesion portion 12 may be circular, oval, or other suitable shapes.

The inner pan 10 is generally cylindrical and comprises a bottom wall 13 and a side wall 14 extending upwardly from the bottom wall 13, the upper end of the side wall 14 being provided with a radially outwardly extending flange 15. For example, in the illustrated embodiment, the inner pan 10 is cylindrical and the bottom wall 13 is circular. The anti-sticking portion 12 may be provided on the bottom wall 13. The anti-adhesion portion 12 may be distributed on the entire upper surface of the bottom wall 13. Since the food is more likely to stick to the bottom wall 13 due to gravity during the preparation process, for example, when cooking porridge, the anti-sticking portion 12 provided on the bottom wall 13 can prevent most of the food from sticking to the inner pot 10.

Optionally, the anti-adhesive portion 12 may also be provided on the sidewall 14, if needed and/or desired. In the illustrated embodiment, the inner pan 10 may further include an arcuate transition 16 between the bottom wall 13 and the side wall 14. The anti-adhesive portion 12 may also be disposed on the arcuate transition portion 16. With this embodiment, it is further possible to prevent more food from sticking to the inner pot 10.

The plurality of anti-adhesion portions 12 may be uniformly distributed on the inner surface. The plurality of anti-adhesion portions 12 may be arranged in an array, and specifically, the plurality of anti-adhesion portions 12 may be arranged in a row along the first direction D1, and the plurality of anti-adhesion portions 12 are arranged in a column along the second direction D2, the first direction D1 intersecting the second direction D2. In the illustrated embodiment, the plurality of anti-sticking portions 12 arranged in the first direction D1 are arranged in a plurality of rows in the second direction D2. The plurality of anti-sticking portions 12 arranged in the second direction D2 are arranged in a plurality of rows in the first direction D1. If needed and/or desired, a plurality of anti-adhesive portions 12 may be arranged in an annular array with respect to the center of the bottom wall 13.

The inner pot 10 provided by the utility model can be used for cooking appliances, and the inner pot 10 has good non-stick property due to the convex part or the concave part, so that the food can be taken out from the inner pot 10 conveniently; in addition, in the using process of the inner pot 10, the non-stick property of the inner pot 10 can be kept at an expected level all the time, and cannot be reduced along with the long-term use of the inner pot 10, so that the service life of the product and the use experience of consumers are improved.
