The present invention relates to a kitchen appliance and in particular to an integrated multifunctional grill and hot pot.
The electric grill commonly available on the market generally has a structure including a grill pan and a housing with a heating element. The grill pan is detachably placed on an opening at an upper end of the housing and a lower surface of the grill pan abuts against the heating element. After the heating element is energized, users can directly grill or fry various food on the grill pan, such as meat, vegetables, and wheaten food. With the evolution of society and the improvement of living standards, eating habits and lifestyles of many young people are constantly changing. More and more people prefer to use an electric grill to grill food while enjoying various food cooked by other cookers. However, due to factors such as volume and the structure of the grill, the electric grill does not have the function of a hot pot, a cooker or a barbecue. Therefore, the user needs to find another type of cooker, such as using an electric hot pot or a gridiron for barbecuing.

In the present embodiment, a lower end of the hot pot 5 is provided with the heat conducting portion 57. A lower end of the heat conducting portion 57 is concave inward to form the heat conducting groove 58 capable of accommodating the second heating element 6. After assembly, the second heating element 6 abuts against the heat conducting groove 58. The second heating element 6 is wrapped by the heat conducting groove 58, so that the heat conduction efficiency is higher through a contact between the second heating element 6 and the heat conduction groove. An upper end of the hot pot 5 is covered with the hot pot lid 19. During use, the hot pot is covered with the hot pot lid 19, achieving heat preservation of the hot pot 5. A side of the grill pan 2 close to the hot pot cavity 16 is provided with the decorative portion 21 covering an edge of an upper end of the hot pot cavity 16, effectively shielding the structure inside the hot pot cavity 16 so as to make the product look more attractive. The decorative portion 21 is provided with the hot pot opening 22 for inserting the hot pot 5. After assembly, an edge of the hot pot 5 abuts against the decorative portion 21. Two sides of the upper end of the housing 1 which are respectively concave inward and an edge of the grill pan 2 form the handle groove 14 for inserting fingers. The above-mentioned structure is ingeniously designed for conveniently holding the grill pan 2 when cleaning.
