Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable warmer which carries a fuel and heats and keeps a human body using heat generated by combustion.

[0002]

2. Description of the Related Art A hand warmer using combustion heat of petroleum-based fuel such as benzene has been well known as a heat source used for portable heating. As disposable hand warmers, those utilizing a chemical reaction between a metal such as iron and an oxidizing agent are also widely used.

[0003]

However, the conventional hand warmer described above has a small heating value and can only perform local heating.
It is impossible to heat the entire body by itself, and there is a drawback that a sufficient heating effect cannot be obtained unless a large number of them are worn separately. In addition, since it is difficult to arbitrarily control the heat generation temperature of this kind of hand warmer, it is not possible to heat the desired temperature depending on the purpose of use and place.

To combat such a problem, it is conceivable to use a combustor which generates a large amount of heat and whose heat generation temperature can be adjusted. Even under various use conditions, there is a problem of a heat diffusion structure and means for treating air supply and exhaust to sufficiently secure air required for combustion and for distributing heat over a wide area of the body due to an increase in heat generation. Becomes

Accordingly, the present invention provides a combustor having a large calorific value attached to a human body to heat the body over a wide area and to reduce or stop the calorific value during use by a short circuit of air supply and exhaust. It is intended to provide a warmer that does not need to be performed.

[0006]

SUMMARY OF THE INVENTION The present invention comprises a heat source unit using combustion heat as a heat source, a fuel tank unit storing fuel to be supplied to the heat source unit, and a control unit for controlling combustion of the heat source unit. The heat source unit is housed in a storage case provided with a belt unit for fixing the heat source unit to the human waist, and the air supply passage or the exhaust passage is connected to one or both of the air supply port and the exhaust port provided in the heat source unit. By isolating the supply air and the exhaust air in this way, sufficient air required for combustion can be secured and stable combustion can be maintained.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An invention according to claim 1 of the present invention controls a heat source section using combustion heat as a heat source, a fuel tank section storing fuel to be supplied to the heat source section, and controlling combustion of the heat source section. And a storage case comprising a belt portion and a storage portion, wherein the heat source portion is stored in a storage portion of the storage case to be fixed to a human waist, and an air supply port and an exhaust port are provided in the heat source portion. Provided, at least one of which is connected to a passage communicating with the outside of the storage case to isolate the supply air and exhaust gas, and it is possible to prevent a short circuit for re-supplying exhaust gas after combustion and prevent shortage of air. Combustion does not become unstable.

According to a second aspect of the present invention, in addition to the first aspect of the present invention, one of the passages extends to the belt portion, so that the supply port and the exhaust port are separated from each other. Therefore, the short circuit can be more reliably prevented.

According to a third aspect of the present invention, there is provided a heat source unit that uses combustion heat as a heat source, a fuel tank unit that stores fuel to be supplied to the heat source unit, a control unit that controls combustion of the heat source unit, and a belt unit. And a storage case comprising a storage portion, wherein the heat source portion is stored in a storage portion of the storage case to be fixed to a human waist, and an air supply port and an exhaust port are provided in the heat source portion and connected to the air supply port. The passage that extends to the belt section, and the passage that connects the exhaust port communicates with the lower part of the storage section, thereby ensuring the separation between the air supply port and the exhaust port, and being heated by the heat source section. The exhaust is discharged from below the storage case fixed to the waist. Therefore, it is not necessary to waste hot air, and the moisture contained in the exhaust gas is quickly released to the outside, so that the warm air for warming the human body does not include moisture, and a comfortable heat retention can be realized. Further, by directing the exhaust direction downward, even when the garment is worn from above, the exhaust gas can be directly discharged from the skirt to the outside of the garment, and the reliability for combustion is further improved.
