Referring to fig. 1, the present application provides a stewpot, which includes a pot body 10, a heat generating plate 20 and an inner pot 30. It can be understood that the inner pot 30 is a pottery pot, and the food cooked in the pottery pot can retain more nutrition and original flavor of the food, so that the food is delicious and healthy.

The pot body 10 is provided with a cavity 101, the heating plate 20 is arranged in the cavity 101, and the inner pot 30 is arranged on the heating plate 20. The outer bottom wall of the inner pot 30 is provided with a ring-shaped supporting leg 31, and the supporting leg 31 has a heated surface 311 capable of being abutted against the heating plate 20, that is, when the inner pot 30 is placed on the heating plate 20, the heated surface 311 is in direct contact with the heating plate 20, so that the heating plate 20 can directly heat the inner pot 30 through contact.

Referring to fig. 2 and fig. 3, in the present application, the heated surface 311 is annular, and the annular width D of the heated surface 311 is 5mm to 50 mm. Thus, a certain contact area between the inner pot 30 and the heating plate 20 can be ensured, so that more heat can be directly transferred to the inner pot 30 through the support legs 31, the thermal efficiency of the stew pot can be improved, and the temperature rise of the pot body 10 can be correspondingly reduced.

If the ring width D of the heated surface 311 is too small, the heat quantity directly transferred from the heating plate 20 to the inner pan 30 is small, and if the ring width D of the heated surface 311 is too large, the bottom of the inner pan 30 is easily deformed during the firing process, and the heated surface 311 is difficult to maintain in a flat state, thereby affecting the contact area between the inner pan 30 and the heating plate 20. Preferably, the ring width D of the heated surface 311 is 20mm to 40 mm. The ring width D in this range can ensure that the supporting leg 31 has a larger heating surface 311, so that the area of the heating plate 20 in direct contact with the inner pan 30 is larger, and more heat is directly transferred from the heating plate 20 to the inner pan 30; and the heat receiving surface 311 is ensured to be maintained in a flat state without being deformed, thereby ensuring that the heat receiving surface 311 can be in direct contact with the heat generation plate 20.

Further, the portion of the outer bottom wall of the inner pot 30 located inside the leg 31 is recessed toward the inside of the inner pot 30.
