In addition, although the electric kettle is used as the description in the embodiment, the creation of the present invention is not limited thereby. In other embodiments not shown, the kitchenware heating assembly can also be applied to kitchen utensils such as a quick-cooking pot, and the like. The same heating means achieves the same heating effect as in the present embodiment.

In this embodiment. The heating plate 110 includes a disk body 112 having a top plane 112a and a bottom structure 114 including a plurality of protruding structures 114a-114d extending from the disk body 112 to face the top plane 112a, respectively. Here, the heating plate 110 is, for example, an integral structure formed of an aluminum material, such as casting, in which the purity of aluminum is greater than or equal to 99.7%. Correspondingly, the material of the container 130 is stainless steel. Accordingly, in order to allow the container 130 and the heating plate 110 to be smoothly combined with each other, the kitchen heating assembly 100 of the present embodiment further includes a solder layer 120 to allow the top surface 112a of the heating plate 110 to be bonded to the top layer 112a by the solder layer 120. The outsole plane 132 of the container 130 is designed to achieve the effect of dissimilar metal bonding. At the same time, since the solder layer 120 is made of a material having good heat conduction effect (for example, aluminum-based solder), the top surface 112a can be completely attached to the outer bottom surface 132, so that the heat generated by the heating tray 110 is evenly distributed.
