対流伝熱量を増加させる事が本発明の課題である。The energy transmitted to the cooking pot is part of the combustion energy, and most of the energy is dissipated into the atmosphere as wasted energy. The goal is to reduce this radiated energy as much as possible, in other words, to use it more as cooking energy. The biggest obstacle to transferring more heat to the contents of the pot is not the thermal conductivity of the material of the pot or the heat transfer between the inside and the contents of the pot, but rather the outer surface of the pot. Heat transfer resistance with flames and hot combustion gases. Heat on the outer surface of the pot
Radiated heat transfer from large flames and hot combustion gases
And convective heat transfer from hot combustion gases. Of these two
It is an object of the present invention to increase the amount of convective heat transfer .

The valley, which is a groove, is a concave part, and the ridges beside the ridges are convex parts (6), and the valley bottom and the peak are better rounded than sharp corners. The concave portions and convex portions are formed radially, and a large number of concave portions and convex portions are formed on the outer surface in the vertical direction all around. Made of the same material as the pan, the radial groove (3) and the vertical groove (5) when making the pan
Is best formed on the outer surface. Some pots are shallow, like a frying pan, and some are deep. Depending on the shape of the pot,
Groove processing may be performed on only one of the outer bottom surface and the outer surface. The inner surface of the pot is smooth, and the shape of the pot may be round or polygonal. The radial groove formed on the outer bottom surface of the pot from the center to the outer periphery and the vertical groove formed on the entire periphery of the outer surface serve as a flow passage groove that does not hinder the flow of the high-temperature combustion gas, and at the same time a valley that is a groove. The heat transfer area of the outer surface is increased by the unevenness of the mountain, and the amount of convective heat transfer is increased to increase the effective use of combustion energy.
