[0002] A composite bottom sheet for a cooking appliance is typically a sheet structure composed of two or more different materials. It is fixed or attached to the bottom of the pot. Common composite bottom sheet structures include stainless steel combined with a metal with good thermal conductivity, such as aluminum or copper. These composite materials are designed to combine the advantages of different materials to achieve better cooking results.

[0003] Problems with existing technologies:

[0004] The connection surface between the composite bottom sheet and the pot bottom currently used is usually smooth, so it is easy to fall off or deform due to thermal expansion during long-term heating and use. Thermal conductivity will lead to reduced thermal efficiency and prolong cooking time, shortening the service life of the equipment and increasing operating costs. In addition, after the cooker is used, the temperature of the composite bottom sheet and the pot bottom cannot be known, which can easily burn the tabletop or burn the user, reducing the safety of the equipment.

[0008] The composite film body consists of a first stainless steel layer, an aluminum layer and a second stainless steel layer. The second stainless steel layer is arranged on the top of the aluminum layer, and the first stainless steel layer is arranged on the top of the aluminum layer.

[0009] The convex surface of the arc-shaped connecting piece is provided with a reinforcing rib for preventing the arc-shaped connecting piece from breaking.

[0010] The temperature sensing plate is made of a memory alloy or a temperature sensing color-changing ceramic.

[0011] The outer wall of the complex negative body and between the circular holes is provided with a plurality of waist grooves in the circumferential direction.

[0012] The technical effects achieved by the utility model are as follows:

[0013] The notch can effectively disperse the stress received by the complex negative body when heated, avoid deformation of the body, prolong the service life, the arc-shaped connecting piece further prevents deformation of the complex negative body, and improves the use strength of the complex negative body.
