Document Type and Number:
WIPO Patent Application WO/2017/004962
Kind Code:
A1
Abstract:
A composite braze welding and induction heating-type cooking tool comprises a cooking tool body made of a first material, wherein the outer surface of the bottom of the cooking tool body is connected with the inner surface of a heat distribution plate (3) through a braze welding transition material (2)by braze welding ; the heat distribution plate (3) is made of a ferromagnetic heat conduction material; a groove (11) is provided in the middle of the outer surface of the bottom of the cooking tool body; an annular groove (12) is further provided in the periphery of the bottom of the groove (11); the annular groove (12) is formed by further expending the groove (11) in the depth direction; a hole (31) with the shape and the position corresponding to the groove (11) is formed in the middle of the heat distribution plate (3); an inward flanging structure (32) with the shape and the position corresponding to the annular groove (12) is arranged around the hole (31); and when the heat distribution plate (3) is connected with the outer surface of the bottom of the cooking tool body by braze welding, the inward flanging structure (32) extends into the groove (11) and falls into or stick into the annular groove (12). The product has the advantages that the heating area is large, and the heating temperature is uniform. A product mark can be directly coined at the bottom. During manufacture, the ferromagnetic heat conduction material composite bottom can be conveniently positioned and can prevent the overflowing of solder.
