A outer pot for being directed at cooking pot's interior pot heats

The utility model provides an outer pot for being directed at cooking pot's interior pot heats, includes the pot body, heating tube, its characterized in that: the periphery of pot body bottom surface is opened there is the heating tube mounting groove, the heating tube is placed in the heating tube mounting groove, the lateral wall of heating tube mounting groove has to the sunken rolling groove of the internal side of pot, and this rolling groove bottom is hugged closely and is blocked the heating tube. Compared with the prior art, the beneficial effects of the utility model are that, because rolling groove fixes the heating tube on the metal pot, firm the fixing the heating tube on the metal pot of ability, processing step is few, simple structure, the quality is lighter, therefore the heat conductivity is good, longe -lived, with low costs, and the transportation is convenient to the outer pot can carry on earlier forming the subassembly with the heating tube roll extrusion again behind the surface treatm
