[0002]

2. Description of the Related Art As portable heaters, gas stoves, pocket furnaces, etc., which use petroleum-based fuel as an energy source, are widely used. However, the gas stove is dangerous because it is an open flame, and most of the heat energy is released into the atmosphere, resulting in low heating efficiency. A pocket hearth can only heat part of the human body.

Therefore, heating clothes, mats, etc., which are equipped with a battery and in which electric resistors are distributed, have been considered. However, current batteries have low energy density per weight and cannot supply sufficient heat to heating clothes or mats for a sufficient time. If a sufficient amount of heat is supplied for a sufficient time, the battery becomes large and extremely heavy, which makes it unsuitable for carrying.

Therefore, a petroleum-based fuel having a much higher energy density than a battery or the like is heated by utilizing catalytic combustion to heat a liquid such as water and circulate the liquid having a proper temperature in clothes to warm the whole. Heating clothing is being developed.

【Example】

(Embodiment 1) A first embodiment of the present invention will be described below. FIG. 1 is a plan view of this embodiment, and FIG. 2 is a side sectional view. Reference numeral 1 is a heating sheet forming the surface of the portable mat, which is made of heat conductive fibers. Examples of the heat-conducting fibers include those woven with aluminum-plated glass yarn having good heat diffusion properties, those woven with carbon fibers, etc., and dispersed in a flexible synthetic resin binder around yarns such as natural fibers or synthetic fibers. A metal particle layer is formed, a metal fiber is used, or a metal fiber and a fiber other than the metal fiber are woven. On the back surface of the heating sheet 1, a fiber 2 having a high heat insulating property such as a fiber also used as a heat insulating material is bonded. The heating portion 4 is joined to one end of the heating sheet 1. This joining is performed by firmly sandwiching the heating sheet 1 in the heating portion 4 using the joining screw 3 and pressing the heating portion 4 to the heating sheet 1. As the heat generating portion 4, the combustion catalyst 13
A gas catalytic combustion device 17 equipped with an ignition device 14 is used.

The gas catalytic combustion device 17 has the following structure. The gas cylinder 6 includes a gas opening / closing valve 7 that can be opened / closed by an opening / closing knob 8. In addition, 9 is a gas on-off valve 7
It is an opening / closing spring that urges the opening direction. When the opening / closing knob 8 is opened, the gas emitted from the gas cylinder 6 is ejected from the gas ejection nozzle 10 and flows through the ejector 12 together with the air sucked from the air intake 11 by the gas flow suction effect. Reference numeral 13 is a combustion catalyst, 14 is an igniter, and 15 is a jet of mixed gas, which supplies the mixed gas to the burning catalyst 13. Reference numeral 16 is a protective cylinder that protects the combustion catalyst 13.

The operation of this embodiment will be described below. When the opening / closing knob 8 is operated to open the gas opening / closing valve 7, gas is ejected from the gas cylinder 6 via the gas ejection nozzle 10.
It is mixed with the air sucked from the air intake 11 and becomes a combustible mixed gas. When the ignition device 14 is operated in this state, the mixed gas starts flame combustion and instantly raises the temperature of the combustion catalyst 13 to a temperature at which catalytic combustion is possible. In this way, the catalytic combustion heat is uniformly radiated from the protective cylinder 16 to heat the entire heat generating portion 4. Since the heating portion 4 is pressed against the heating sheet 1, the heat generated by the heating portion 4 is reliably transmitted to the heating sheet 1. Further, since the heating sheet 1 is composed of the heat conductive fiber, the heat generated by the heating portion 4 is efficiently transmitted to the entire surface of the heating sheet 1. The back surface of the heating sheet 1 is a fiber 2 having a high heat insulating property made of fibers such as fibers, and the amount of this heat escaping from the back surface is small. Therefore heating sheet 1
The whole is kept at an appropriate temperature and can be used as a portable heat retaining mat. Since this heat retaining mat is highly flexible, it can be used by being wrapped around the body, for example.

As shown in FIG. 3, the heating sheet 1
If it is configured to be used for clothes, it is possible to configure heating and heat retaining clothes, and it is possible to realize a portable heating and warming device that can be used in highlands, offshore and cold regions where it is difficult to supply power and gas. is there.

As described above, this embodiment has a very simple structure as compared with the conventional structure in which a liquid such as water is used to heat the object to be heated and the object to be heated and the heat source are connected by a tube. It is lightweight, highly flexible, and convenient for heating.
This is what realizes the warmer.

At this time, as shown in FIG. 4, if the heat generating portion 4 is joined to a part of the heating sheet 1 through a heat conductive material 18 such as a heat conductive compound or thermo grease, the heat generating portion 4 is further improved. It is possible to realize a heater / heater with improved thermal efficiency. That is, the heat transfer between the heat generating part 4 and the non-contact part of the heating sheet 1 is supplemented by the heat conductive material 18, and the heat of the heat generating part 4 is more reliably transferred to the heating sheet 1. So in this case, the fuel consumption is reduced,
It realizes a heating / warming device that can be used for a longer period of time.

Further, at this time, as shown in FIG. 5, a plurality of protrusions 20 are provided on the contact surface of the heat generating portion 4 with the heating sheet 1, and the heat conducting fibers are woven so as to be entangled in the protrusions 20. In such a case, the contact area between the heat generating part 4 and the heating sheet 1 is further increased. Therefore, the heat of the heat generating portion 4 is more efficiently transferred to the heating sheet 1.

(Embodiment 2) Next, a second embodiment of the present invention will be described with reference to FIGS. FIG. 6 is a plan view of this embodiment, and FIG. 7 is a side sectional view of this embodiment.
Reference numeral 21 is a holding base made of a metal having good thermal conductivity such as aluminum or copper, and is provided by being pressed against a part of the heating sheet 1 by the joining screw 3. The heat generating part 4 is attached to the holding table 21 with fixing screws 22.

The operation of this embodiment will be described below. When the opening / closing knob 8 is operated to open the gas opening / closing valve 7 as described above, gas is ejected from the gas cylinder 6 via the gas ejection nozzle 10 and mixed with the air sucked from the air intake 11 to be combustible. It becomes a mixed gas. When the ignition device 14 is operated in this state, the mixed gas starts flame combustion and instantly raises the temperature of the combustion catalyst 13 to a temperature at which catalytic combustion is possible.
The catalyst combustion heat thus generated is uniformly radiated from the protective cylinder 16 and heats the entire heat generating portion 4. This heat is generated by the holding table 2
1 to the heating sheet 1. At this time, the holding table 21
Is pressed against the heating sheet 1, and this heat transfer is surely performed. The heating sheet 1 is composed of heat conductive fibers, and has fibers 2 having a high heat insulating property such as fibers attached to the back surface thereof. Therefore, Example 1
Similarly to the above, the present embodiment realizes a heater / heater that is lightweight, highly flexible, and convenient to carry.

At this time, according to the present embodiment, the heat generating portion 4
Since it is configured to be held on the holding table 21, it is possible to realize a heating / warming device in which the heat generating portion 4 can be easily attached and detached and maintenance is easy.

At this time, as shown in FIG. 8, the contact surfaces of the heat generating portion 4 and the holding base 21 are both mirror-finished surfaces 23.
Then, the degree of close contact between the heat generating part 4 and the holding table 21 is increased, and a heating / warming device with further improved thermal efficiency can be realized.

(Third Embodiment) Next, a third embodiment of the present invention will be described with reference to FIGS. 9 is a plan view of this embodiment, and FIG. 10 is a side sectional view of this embodiment. In this embodiment, the heating portion 4 is wrapped with a part of the heating sheet 1.

Therefore, almost all the heat generated by the heat generating portion 4 is transferred to the heating sheet 1 without being radiated to the outside. That is, it realizes a heating / insulating device with extremely high thermal efficiency.
