DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooking pot.

[0002]

2. Description of the Related Art Conventionally, cooking pots are made of a material such as iron, aluminum, or copper, which is formed into a smooth surface, and a spiral or concentric groove is formed on the bottom surface of the pot. is there. Some pans have multiple layers of pot walls to improve the thermal conductivity of the material itself.

[0003]

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 .

[0004]

A number of radial grooves (3) extending from the center of the outer bottom surface (2) of the pot (1) to the outer periphery.
Are provided, and a number of vertical grooves (5) are provided on the outer side surface (4). Or a number of upper and lower parts on the outer surface (4) of the pan (1)
A groove (5) is provided.

[0005]

[Function] A large number of radial grooves (3) formed on the outer bottom surface of the pot and a large number of vertical grooves (5) formed on the outer surface form flow grooves that do not impede the flow of the high-temperature combustion gas, and the surface heat transfer. while preventing a decrease in the coefficient, it is possible to increase the amount of heat transferred by convection because increasing the outer surface heat transfer area in the groove size and mountains. This
This is intended to increase the effective use of combustion energy.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In a pot (1), a number of vertical grooves (5) are formed on an outer surface (4) and a number of radial grooves (3) are formed on an outer bottom surface (2). 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.

[0007]

The present invention is as described above, but has the following effects. How the hot combustion gas flows on the outer surface of the pot
The grooves formed in the direction prevent the convective heat transfer coefficient from decreasing and
The amount of heat transferred to the contents of the pot as the outer surface heat transfer area is increased
Increase the effective use of combustion energy
You.
