Secondly, electric slow cookers are easy to operate; simply put the ingredients in the pot, set the program, and the cooking process will be completed automatically, saving time and effort.

[0003] Application number CN202322523534.X discloses an intelligent electric slow cooker, belonging to the field of food processing technology, aiming to overcome the drawback of the high manufacturing cost of the outer pot in existing slow cookers.

The upper surface of the support cover is in contact with the bottom of the ceramic inner pot.

[0004] In the aforementioned patent, because the heating device is located at the bottom, the bottom of the ceramic inner pot receives more heat during heating, while the sides receive less heat, resulting in the food not being heated evenly. Utility Model Content

[0005] In view of the shortcomings of uneven heating in existing electric slow cookers, this utility model provides an electric slow cooker that can be heated evenly.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: an electric slow cooker that can be heated evenly includes an outer pot body, a ceramic inner pot, and a top cover. The outer pot body includes a shell and a heat-conducting inner pot disposed within the shell. The shell has an inner cavity and the heat-conducting inner pot is embedded in the inner cavity. A heating plate is provided at the bottom of the inner cavity. The ceramic inner pot is disposed within the heat-conducting inner pot, and the bottom of the heat-conducting inner pot abuts against the heating plate. The thickness of the ceramic inner pot gradually increases from top to bottom, and the outer diameter gradually decreases. The distance between the outer wall of the ceramic inner pot and the outer wall of the heat-conducting inner pot gradually increases from top to bottom.

[0007] Preferably, the sidewall thickness of the heat-conducting inner liner is uniform and the outer diameter of the heat-conducting inner liner gradually decreases from top to bottom.

[0008] Preferably, the thickness of the bottom wall of the ceramic inner liner is greater than the thickness of its side wall.

[0009] Preferably, the top of the shell is provided with a first annular step along the circumference, and the top of the heat-conducting inner liner is provided with a first hanging edge extending outward horizontally along the circumference, the first hanging edge hanging on the step surface of the first step.

[0015] Preferably, the heat-conducting inner liner is made of aluminum.

[0016] Compared with the prior art, the advantages of this utility model are as follows: Since electric slow cookers need to simmer over low heat, this solution takes into account the different heat conduction efficiencies at different positions of the heat-conducting inner pot, and sets the distance between the ceramic inner pot and the heat-conducting inner pot and the thickness of the ceramic inner pot differently from top to bottom, thereby reducing the heat conduction efficiency at the bottom and increasing the heat conduction efficiency at the top, thus narrowing the gap in heat conduction efficiency at different positions and improving the uniformity of heating.

[0024] Example

[0025] An electric slow cooker that can heat evenly, such as Figure 1-4 As shown, the device includes an outer pot body 10, a ceramic inner pot 40, and a top cover. The outer pot body 10 includes a shell and a heat-conducting inner pot 30 disposed within the shell. The shell has an inner cavity, and the heat-conducting inner pot 30 is embedded in the inner cavity. A heating plate 50 is provided at the bottom of the inner cavity. The ceramic inner pot 40 is disposed within the heat-conducting inner pot 30, and the bottom of the heat-conducting inner pot 30 abuts against the heating plate 50. The thickness of the ceramic inner pot 40 gradually increases from top to bottom, while its outer diameter gradually decreases. The distance between the outer wall of the ceramic inner pot 40 and the outer wall of the heat-conducting inner pot 30 gradually increases from top to bottom. Since electric slow cookers require slow simmering, this design takes into account the different heat conduction efficiencies at different locations of the heat-conducting inner pot 30. The distance between the ceramic inner pot 40 and the thickness of the ceramic inner pot 40 are differentiated from top to bottom, thereby reducing the heat conduction efficiency at the bottom and increasing the heat conduction efficiency at the top, thus narrowing the difference in heat conduction efficiency at different locations and improving the uniformity of heating.

[0026] Preferably, the heat-conducting inner liner 30 has a uniform sidewall thickness and its outer diameter gradually decreases from top to bottom. The distance between the heat-conducting inner liner 30 and the ceramic inner liner 40 can be further adjusted by configuring the heat-conducting inner liner 30.

[0027] Preferably, the thickness of the bottom wall of the ceramic inner liner 40 is greater than the thickness of its side walls. A thicker bottom helps reduce heat absorption at the bottom, preventing overheating.

[0029] Preferably, the first step 102 has a plurality of protrusions 104 on its surface, and the first hanging edge 301 has a plurality of notches 3011. The protrusions 104 and notches 3011 are shaped and correspond one-to-one, and the protrusions 104 extend into the notches 3011. The protrusions 104 are used to limit the heat-conducting inner liner 30.

[0030] Preferably, the top of the shell is provided with a ring-shaped second step 103 along the circumference, and the top of the ceramic inner liner 40 is provided with a second hanging edge 401 extending outward horizontally along the circumference, which hangs on the step surface of the second step 103.

[0031] Preferably, the top surface of the boss 104 is flush with the step surface of the second step 103, or the top surface of the boss 104 is lower than the step surface of the second step 103.

[0032] Preferably, the lid 20 has a wooden handle 201 in the middle, a vent 202 on the side, and a snap-fit ​​opening 200 on the outer edge. The lid 20 fits onto the step surface of the second step 103, and the snap-fit ​​opening 200 on its outer edge engages with the outer wall and step surface of the second step 103. When the lid 20 is closed, it can position the ceramic inner liner 40, ensuring its positional accuracy.

[0033] Preferably, a pair of pot handles 101 are provided on the outer wall of the shell. The pot handles 101 are used to move the electric slow cooker.

[0034] As a preferred option, the thermally conductive inner liner 30 is made of aluminum. Aluminum inner liners are characterized by low cost and excellent thermal conductivity.
