[0008] With such a shape, when water is poured into the kettle and ignited, heat rising from the bottom of the kettle along the body is received by the lower surface of the overhang, and the overheat is received by the received heat. The water existing in the hollow interior of the part can be heated and efficiently turned into hot water. Further, by forming the overhanging portion so as to be inclined downward and overhanging, the overhanging portion does not become extremely obstructive, and does not cause a remarkable discomfort compared to a normal kettle.

It is desirable that the overhanging portion be formed in the kettle main body at a position lower than the center of the height of the main body, and the lower protruding portion extends from the bottom of the kettle main body to the outer periphery of the torso. Can quickly catch the rising heat and contribute to the effective use of heat, and when boiling hot water with a small amount of water, it is possible to hold the water in the overhang provided at this low position. Therefore, the effect of the heating by the overhanging portion can be enhanced, and the overhanging portion can block the rising hot air to moderate the propagation of heat to the handle, thereby maintaining safety.

[0010] In order to continue the combustion by appropriately escaping the exhaust gas generated by the combustion along the overhanging portion and continue the combustion, the overhanging portion is slightly inclined with respect to the central bottom portion where the kettle body is heated. It is desirable to be at a high position.

In the method of manufacturing a kettle according to the present invention, the kettle main body is formed by forming a pair of divided bodies having a shape obtained by dividing the main body part into upper and lower parts, and forming a projecting edge on the outer periphery of the lower edge of the upper divided body.
In addition, an overhanging edge is formed on the outer periphery of the upper edge of the lower split body so as to match the overhanging edge of the upper split body so that the mutual edges can be brought into contact with each other, and the edges of the two opposite edges are formed over the entire circumference. The hollow overhang can be easily formed by welding over the entire surface.

[0012]

The kettle of the present invention has a hollow overhang formed on the outer periphery of the body of the main body, and the overhang is substantially added to the bottom of the normal kettle to increase the heat receiving area of the kettle. Then, the heat rising from the bottom of the kettle along the trunk is caught, and the water inside the overhang can be heated by this heat to efficiently boil the water.

Further, the heat received by the overhang is hollow inside the overhang, and the hollow communicates with the inside of the kettle body. In addition, since the overhanging portion blocks hot air and suppresses a rise in heat, the handle provided at the upper portion of the main body is prevented from being heated, and handling of the kettle is made safe.
