Abstract

PURPOSE:To obtain a cover improving heat efficiency and preventing gas leakage by a method wherein an outer peripheral part is surrounded by a belt-like plate member and both end parts are put over so as to be able to expand and contract corresponding to a size of diameter of a pot of the like. CONSTITUTION:A cover 1 is formed by a belt-like plate member 2 made of a heat-resisting member such as a steel plate and bent in a ring, with both end parts put over. An upper opening part of the cover 1 is provided with a fastening part 5 to attach tight to an outer peripheral part of a heating container 4 such as a pot. The fastening part 5 is engaged with the outer peripheral part of the heating container 4 and wound with a wire 6 to reduce its diameter so that it is mounted tight on the outer peripheral part of the heating container 4. Thus combustion heat from tinders 9 of a gas range 8 heats a bottom part of the heating container 4 and gathers in a space 10 between the cover 1 and the heating container 4, further heating the container 4. In the case that water, for example, in the container 4 overflows, the water flows down along the belt-like plate member 2 from the fastening part 5 of the cover 1 and drops down from a lower end without dropping down into the tinders 9.

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cover for a pot, etc., which is attached to a pot or the like when heating a heating container such as a pot or kettle on a gas stove or the like.

0002

[Prior Art] Generally, in order to boil water or cook food, etc., a container a such as a pot or kettle is placed on the burner c of a gas stove b, as shown in FIG. This is done by heating the bottom part by burning gas.

0003

[Problems to be Solved by the Invention] As shown in the figure, the bottom of a container a such as a pot or a kettle is often formed in a U shape, so that the combustion heat of the gas stove b is transferred to the container a.
Thermal efficiency was poor as the heat escaped from the bottom side of the unit. In addition, hot water, etc. that spills from container a may travel along the outer periphery of container a, reach the bottom, and fall, extinguishing the flame of gas stove B. In this case, gas may leak and become extremely dangerous. Met.

[0004] Therefore, the present invention was devised to effectively solve these problems, and its purpose is to prevent loss of combustion heat in a gas stove, improve thermal efficiency, and prevent gas leakage. This provides a cover for pots, etc. that allows for

[0005]

[Means for Solving the Problems] The present invention surrounds the outer periphery of a pot, etc. with a band-shaped plate member, and overlaps both ends of the plate member so that the pot, etc. can be expanded or contracted according to the diameter of the pot, etc. It is formed and configured.

[0006]

[Operation] Since the present invention is constructed as described above, the band-shaped plate member can prevent the combustion heat of the gas stove from diffusing. In addition, since boiling hot water from a pot or the like is guided by the band-shaped plate member and flows down from the end thereof, there is no risk of the gas stove going out. Furthermore, since this band-shaped plate member is formed to be expandable and contractible, it can be attached to pots, etc. of different diameters.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of a cover for a pot or the like according to the present invention, FIG. 2 is a plan view thereof, and FIG. 3 is a side view thereof. As shown in the figure, a cover 1 for a pot or the like is formed by bending a plate member 2 formed into a belt shape from a heat-resistant member such as a steel plate into an annular shape, and overlapping both ends 3 of the plate member 2, as shown in FIG. It is used by being attached to surround the outer periphery of a heating container 4 such as a pot or kettle.

[0009]Furthermore, as shown in the figure, the cover 1 for a pot or the like has a tightening portion 5 formed in its upper opening portion to be tightly attached to the outer periphery of a heating container 4 such as a pot or the like. Further, since the diameter of this tightening portion 5 is formed to be slightly smaller than the diameter of the lower opening, the cover 1 for this pot etc. has a skirt shape. Therefore, when this cover 1 for a pot or the like is attached to a heating container 4 such as a pot, a predetermined gap 10 is formed between the cover 1 for the pot or the like and the lower part of the outer periphery of the heating container 4 for the pot or the like as shown in FIG. will be done.

Further, a wire 6 is wound around the tightening portion 5 along its outer periphery, and this wire 6 is attached to the outer end 3 of the overlapping strip-shaped plate members 2 and is attached to the tightening portion. It is wound up or unwound by a winding section 7 fixedly provided at a position 5. Therefore, the diameter of the tightening part 5 of the cover 1 for this pot or the like can be expanded or contracted by winding or letting out the wire 6 by the winding part 7.

Next, the operation of this embodiment will be explained.

As shown in FIG. 4, in order to attach the cover 1 of this pot etc. to the outer periphery of the heating container 4 such as a pot, first, the cover 1 of this pot etc. is attached to the outer periphery of the heating container 4 such as a pot. This is achieved by fitting the wire 6 around the wire 6 using the winding section 7, reducing the diameter of the tightening section 5, and bringing the tightening section 5 into close contact with the outer periphery of the heating container 4, such as a pot.

By attaching the cover 1 of the pot, etc., the combustion heat from the fire pit 9 of the gas stove 8 heats the bottom of the heating container 4, such as a pot, and is transferred from the bottom of the heating container 4 to the cover 1 of the pot, etc. It gathers in the gap 10 between the heating container 4 such as a pan, etc., and further heats the heating container 4 such as a pot. Therefore, the contact time between the combustion heat and the heating container 4 such as a pot becomes longer than before, the heat exchange efficiency is improved, and the heating container 4 such as a pot
This will shorten the boiling time. Furthermore, even after the gas stove 8 is turned off, the cover 1 itself of the pot etc. is heated to a high temperature, so it also has a heat retention effect. In addition, when the hot water etc. in the heating container 4 such as a pot boils and overflows, the overflowing hot water etc. can be removed from the tightening part 5 of the cover 1 of the pot etc.
It is guided from there to the band-shaped plate member 2, and falls from the lower end of the band-shaped plate member 2. Therefore, overflowing hot water or the like will not flow to the bottom of the heating container 4 such as a pot and fall into the crater 9, making it possible to prevent gas leakage. Next, in order to remove the cover 1 of the pot or the like from the heating container 4 such as a pot, the wire 6 is let out by the winding section 7, the diameter of the tightening section 5 is expanded, and the outer periphery of the heating container 4 such as a pot or the like is expanded. This is achieved by unraveling the close contact between the two. In addition, since the cover 1 for this pot etc. has both ends 3 of the band-shaped plate member 2 overlapped, its diameter can be expanded or contracted according to the diameter of the heating container 4 such as a pot to which it is attached. There is. Therefore, the cover 1 for this pot or the like can be attached to heating containers 4 such as various pots or the like having different diameters.

[0014]

[Effects of the Invention] As detailed above, according to the present invention,
Since the thermal efficiency is improved, heating time is shortened, energy saving is achieved, and the heat retention effect of the pot is also improved. Further, it has an excellent effect of improving safety by making it possible to prevent extremely dangerous situations such as gas leaks.
