Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

First, the technical idea of the technical proposal disclosed by the invention is explained. The liner with nonstick effect in the prior art is usually realized by spraying a chemical coating on the inner surface of the liner body 1, and the coating can be worn and fall off after long-time use, so that the continuous use of the liner can have a certain influence on the health of a user.

In order to solve the above problems, as shown in fig. 1 to 2, the present invention provides an easy-to-clean liner, comprising a liner body 1, wherein the liner body 1 comprises a liner opening 101, a liner body 102 and a liner bottom 103 from top to bottom, the inner surface of the liner body 1 is provided with an anti-sticking pattern 2, the anti-sticking pattern 2 comprises a plurality of grooves 201, the liner body 102 is contracted at least at the upper part, and a contraction wall 1020 connected with the liner opening 101 is formed, such that the anti-sticking pattern 2 groove 201 located at the contraction wall 1020 is opened towards the liner bottom 103.

The anti-sticking pattern 2 on the shrinkage wall 1020, because the shrinkage wall 1020 is shrunk from bottom to top to the inside of the liner body 1, the inner surface of the shrinkage wall 1020 faces to the lower part of the liner bottom 103, so that the opening of the groove 201 in the anti-sticking pattern 2 is also in a state of facing to the direction of the liner bottom 103, namely, facing to the lower part of the horizontal direction. When the rice grains are in contact with the shrink wall 1020, on the one hand, the grooves 201 in the anti-sticking pattern 2 can optimize the non-sticking effect of the liner 1 by reducing the contact area between the rice grains and the shrink wall 1020; on the other hand, the opening of the groove 201 is downward, and in the case that the contact area between the rice grains and the shrink wall 1020 is reduced, the resistance of the rice grains when the rice grains are separated from the inner wall of the shrink wall 1020 is further reduced, so that the rice grains can act on the shrink wall 1020 by the gravity of the rice grains to form downward separation force, and the rice grains are more easily separated from the shrink wall 1020, thereby enhancing the non-sticking effect of the inner surface of the liner body 1.

In the cooking process, the heating device positioned below the liner body 1 heats the liner body 1, the rice water mixture in the liner body 1 generates water vapor after being heated, the water vapor flows to the shrinkage wall 1020 and enters the grooves 201 in the anti-sticking grains 2 so as to gradually cool and gather in each groove 201 to form liquid drops, the liquid drops in each groove 201 form a water vapor layer or water film between the rice grains and the shrinkage wall 1020, and the water vapor layer can infiltrate the contact part of the rice grains and the shrinkage wall 1020, so that the adhesive force between the rice grains and the shrinkage wall 1020 is reduced. Meanwhile, as the liquid drops are formed in each groove 201, the liquid drops can form a force for pushing away the shrinkage wall 1020 on the rice grains covered on the grooves 201, so that the rice grains are easier to fall off from the shrinkage wall 1020, and the non-sticking effect is further optimized.

In one embodiment, the inner surface of the rest of the liner body 102 except the shrinkage wall 1020 of the liner body 1 is also provided with anti-sticking patterns 2, so that the inner surface of the part of the liner body 1 located on the liner body 102 is provided with a plurality of grooves 201, and the contact area between the liner body 102 and rice grains is further reduced. For the rice water mixture located at the lower part of the liner body 102, along with the progress of the cooking process, water is gradually burnt to cause the water level to drop, so that a part of rice grains are in direct contact with the inner surface of the lower part of the liner body 102 under the condition of no water soaking and still in a heating state, the problem that rice grains are adhered to the inner surface of the liner body 1 easily occurs, the arrangement of the embodiment can reduce the contact area between the rice grains at the lower part of the liner body 102 and the inner wall of the liner body 102, and meanwhile, the groove 201 can also play a role of water storage, so that a water film is formed between the rice grains and the inner wall of the liner body 102, the occurrence of the condition that the rice grains are adhered to a pot can be effectively reduced, and the cooking effect is optimized.

In one embodiment, the anti-sticking grain 2 is further disposed on the inner surface of the liner bottom 103, so that the inner surface of the liner bottom 103 is provided with a plurality of grooves 201 with upward openings, and on one hand, the plurality of grooves 201 can reduce the contact area between the rice grains at the bottom of the liner body 1 and the inner surface of the liner bottom 103, thereby realizing a part of non-sticking effect. On the other hand, under the action of gravity of the upper rice grains, the rice grains cover and squeeze the opening of the groove 201, so that the rice grains and the groove 201 form independent cavities, water in the cavity expands and is vaporized when being heated in a relatively airtight environment, when the pressure in the groove 201 reaches a certain degree, gas generated in the groove 201 can push the rice grains covered above the opening of the groove 201, so that the rice grains are separated from the inner surface of the liner bottom 103, gaps are generated, at the moment, the gas in the groove 201 is discharged outwards from the gaps, external water reenters the groove 201, the rice grains separated from the inner surface of the liner bottom 103 are covered with the groove 201 again under the action of self gravity and the pressure of a water mixture of the upper rice, so that the water in the groove 201 is heated again and expanded and generates gas in a relatively airtight environment, and repeatedly, the rice grains are continuously separated from the inner surface of the liner bottom 103, the phenomenon similar to jumping is generated relative to the inner surface of the liner bottom 103, compared with the phenomenon that the rice grains is realized by reducing the contact area with the inner surface of the liner bottom 103, the rice grains can be contacted with the liner bottom 103 in a mode, the cooking effect is greatly reduced, the contact time of the rice grains can be prolonged, and the cooking effect is avoided, and the contact time between the rice grains and the inner surface of the liner bottom is greatly prolonged, and the rice grains are not contacted with the liner bottom 1.

In the invention, the anti-sticking patterns 2 are hydrophilic patterns, the grooves 201 are independent grooves 201, and supporting ribs are arranged between the adjacent grooves 201. The anti-sticking groove 2 on the shrinkage wall 1020 is opened towards the liner bottom 103, so that the hydrophilicity of the hydrophilic grain on the shrinkage wall 1020 is smaller than that of the rest part of the liner body 1, and the phenomenon that the moisture content on the shrinkage wall 1020 is too large to influence the taste of rice is avoided.

As a preferred embodiment of the present invention, as shown in fig. 3 to 5, the middle portion of the liner body 102 protrudes outwards, and the liner body 102 cooperates with the liner bottom 103 to form a spherical cooking cavity inside the liner body 1. In this embodiment, the maximum diameter b of the central outer bulge of the liner body 102 of the liner body 1 is smaller than the minimum diameter a of the liner opening 101. Further, the liner body 1 is a spherical liner. The rice water mixture is located the narrower area of courage body 1 bottom bore, in the culinary art in-process, rice water mixture produces the steam after heating, steam flows the great courage body 102 middle part in space earlier in the inside in-process that flows from bottom to top of courage body 1, the outside convex position of courage body 102, because courage body 1 bore is great here, the space is also great relatively, can hold more steam, the steam continues to flow upwards after gathering here, the shape of spherical courage body 1 is located courage body 102 bore above the bulge and reduces gradually, the space diminishes, thereby produce certain extrusion to the steam that flows upwards, consequently, relative, receive extruded steam also forms certain pressure to shrink wall 1020, steam more easily gets into in recess 201 through the clearance between grain of rice and the recess 201 under the pressure effect, further optimize shrink wall's non-sticking effect. At the same time, the water vapor at the portion of the shrinkage wall 1020 is extruded so that the pressure can be transferred to the water vapor at the outwardly protruding portion of the liner body 102, so that the water vapor at the portion also enters the groove 201 on the inner surface of the liner body 102 more easily, and the non-sticking effect of the liner body 1 is further optimized.

Further, the horizontal projection of the pinch wall 1020 at least partially coincides with the liner bottom 103. The liner bottom 103 is a main heated area of the liner body 1 due to the fact that the liner bottom 103 is directly heated by the heating device, so that the amount of water vapor generated in the area is relatively large, the arrangement of the projection of the shrinkage wall 1020 and the liner bottom 103 enables the vapor generated in the area right above the liner bottom 103 to directly flow to the shrinkage wall 1020, the capability of collecting the water vapor and forming a water vapor layer of the grooves 201 of the anti-sticking pattern 2 on the shrinkage wall 1020 is further improved, and the non-sticking effect of the inner wall of the shrinkage wall 1020 is optimized.

Further, the depth of the groove 201 ranges from 0.02mm to 0.5mm. The hydrophilicity is further optimized by adopting the range, and meanwhile, the situation that water drops are always located at the bottom of the groove 201 and cannot be converged to the opening of the groove 201 in time to form a water film can be avoided because the depth of the groove 201 is too large.
