Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method of lighting a hot pot that does not require any type of spark such as a lighter or a matchstick.

[Conventional technology]

Conventional seaweed involves vaporizing a seaweed fuel such as petroleum benzine and bringing it into contact with an oxidation catalyst such as platinum.
The oxidation catalyst is ignited by bringing a source of spark, such as a lighter or a matchstick, close to the oxidation catalyst.

[Problem that the invention seeks to solve]

Therefore, in order to ignite a conventional hot pot, a spark for burning the hot pot fuel, such as petroleum benzene, is absolutely essential. However, in some cases, it may not be possible to prepare the spark at all, so even if you want to ignite the pot, there is a problem that if there is no spark, you will not be able to ignite it.

[Means for solving problems]

This invention utilizes the fact that when an organic compound with a high oxygen content such as methyl alcohol, formic acid, or acetic acid comes into contact with a low-temperature active oxidation catalyst, an oxidation reaction starts at room temperature and generates heat. That is, a low-temperature active oxidation catalyst that generates heat upon contact with vaporized methyl alcohol is used as an ignition catalyst, and this ignition catalyst is brought into contact with a heat-generating catalyst for coal fuel such as petroleum benzene.

[Effect]

As a result of performing the above means, heat is transferred from the ignition catalyst to the heat generating catalyst, and the temperature of the heat generating catalyst is raised to a temperature higher than the reaction start temperature of the hot pot fuel, and the hot pot fuel is ignited. .

〔Example〕

Hereinafter, a method for igniting a pot according to the present invention will be explained according to an embodiment of a pot used for carrying out the present invention.

Reference numeral 1 denotes a tank body for heating, and this tank body 1 is divided into a large-capacity heat-generating fuel tank part 2 and a small-capacity ignition fuel tank part 3. Absorbent cotton 4 for impregnating with benzene is housed, and absorbent cotton 5 for impregnating with methyl alcohol is housed in the ignition fuel tank section 3. 6 is an exothermic catalyst;
It is provided above the tank opening 7 of the heat generating fuel tank section 2 so as to always communicate with the inside of the heat generating fuel tank section 2. Reference numeral 8 denotes an ignition catalyst, which communicates with the inside of the ignition fuel tank section 3 when it contacts the heat generation catalyst 6, and does not communicate with the inside of the ignition fuel tank section 3 when it does not contact the heat generation catalyst 6. It is provided at the upper part of the ignition fuel tank section 3. For example, as shown in the figure, one end of a spring 9 is connected to the rear end of the ignition catalyst 8 to create a catalyst case 10.
and the other end of the spring 9 is placed in the catalyst case 10.
The ignition catalyst 8 is connected to the rear wall 11 and further presses the rear end of the ignition catalyst 8 so that the ignition catalyst 8 is connected to the catalyst case 1.
A pressing body 12 is provided on the upper surface of the catalyst case 10 so as to be able to slide inside the ignition catalyst 8. , the communication port 13 provided at the lower part of the ignition catalyst 8 connects to the ignition fuel tank section 3.
When the ignition catalyst 8 is not in contact with the heat generating catalyst 6, the pressing body 12 is pulled toward the catalyst case 10 by the spring 9, thereby opening the communication port provided at the lower part of the ignition catalyst 8. 13 is a tank port 14 of the ignition fuel tank section 3
The structure is such that the two are no longer in communication with each other.

Therefore, first, petroleum benzine is poured into the heating fuel tank section 2 to impregnate the absorbent cotton 4, and methyl alcohol is introduced into the ignition fuel tank section 3 and the absorbent cotton 5 is impregnated with it. When igniting the pot, the ignition catalyst 8 is brought into contact with the heat-generating catalyst 6 and the ignition catalyst 8 is communicated with the inside of the ignition tank 3, so that the vaporized methyl alcohol is transferred to the ignition catalyst 8. The ignition catalyst 8 generates heat, and the temperature of the exothermic catalyst 6 rises due to heat conduction from the ignition catalyst 8, igniting petroleum benzine, which is the fuel for cauldron. be done. Next, when the ignition is not to be ignited or after ignition, the ignition catalyst 8 may be prevented from contacting the heat generating catalyst 6, and the ignition catalyst 8 may be prevented from communicating with the inside of the ignition tank portion 3. In this case, methyl alcohol does not vaporize from the ignition fuel tank portion 3 and does not come into contact with the ignition catalyst 8, so the ignition catalyst 8 no longer generates heat.

〔Effect of the invention〕

As described above, the method of igniting a hot pot according to the present invention does not require any kind of spark for ignition, and moreover, the hot pot can be ignited immediately when the hot pot is used, and has excellent effects.
