【Example】
(Example 1)
A first embodiment of the present invention will be described below with reference to FIGS. Reference numeral 1 denotes a heating sheet that forms the surface portion of the portable mat, and is composed of heat conductive fibers. Examples of thermally conductive fibers are those knitted with aluminized glass yarn with good thermal diffusibility, those knitted with carbon fiber, etc., dispersed in a flexible synthetic resin binder around the yarn such as natural fiber or synthetic fiber.

[0023]
The operation of this embodiment will be described below. As described above, when the gas on-off valve 7 is opened by operating the on-off knob 8, gas is ejected from the gas cylinder 6 via the gas ejection nozzle 10 and is combusted by being mixed with air sucked from the air intake 11.

[0025]
(Example 2)
Next, a second embodiment of the present invention will be described. The portable mat of this embodiment has the configuration shown in FIG. That is, a highly heat-permeable heat conductive fiber 19 such as a nonwoven fabric is enclosed in a heat-resistant bag-like heating sheet 20. As shown in FIG. 2, the back surface of the heating sheet 20 is bonded with fibers 2 having high heat insulation properties.

[0026]
The operation of this embodiment will be described below. As described above, when the on-off knob 8 is operated to open the gas on-off valve 7, gas is ejected from the gas cylinder 6 via the gas ejection nozzle 10 and is combusted by being mixed with air sucked from the air intake port 11. It becomes a mixed gas. When the ignition device 14 is operated in this state, the mixed gas starts flame combustion, and instantaneously raises the temperature of the combustion catalyst 13 to a temperature capable of catalytic combustion. When the catalytic combustion is thus started, the combustion gas is discharged into the heating sheet 20 from the exhaust port 18 provided in the protective cylinder 16. This combustion gas flows between the heat conductive fibers 19 having high air permeability and is exhausted from an exhaust port 21 provided at the other end of the heating sheet 20. The heat of the combustion gas is absorbed by the heat conductive fibers 19 when passing between the heat conductive fibers 19, and the heating sheet 20 is uniformly heated by the heat conductive fibers 19. Accordingly, the heat generated by the heat generating portion 4 is efficiently transmitted to the entire surface of the heating sheet 20.

The jetted gas is mixed with the air sucked from the air intake port 11 to become a combustible mixed gas. When the ignition device 14 is operated in this state, the mixed gas starts flame combustion, and the temperature of the combustion catalyst 13 is instantaneously raised to a temperature capable of catalytic combustion. When the catalytic combustion is thus started, the combustion gas is uniformly discharged from the exhaust port 18 provided in the protective cylinder 16. This combustion gas becomes an ascending current and rises at high speed between the heat conductive fibers 19 in the heating sheet 20 to quickly heat the entire surface of the heating sheet 20.

When the on-off knob 29 is operated to open the gas on-off valve 28, gas is ejected from the gas cylinder 27 via the gas ejection nozzle 31 and mixed with the air sucked from the air intake port 32 to become a combustible mixed gas. . The mixed gas flows from the exhaust port 36 provided in the protective cylinder 35 into the introduction pipe 23 and is guided to the catalyst unit 22. When the ignition switch 25 is closed and the ignition heater 24 is energized, the catalyst unit 22 is heated. When the catalyst unit 22 rises to the catalytic combustion temperature, catalytic combustion is started. This combustion gas flows between the heat conductive fibers 19 having high air permeability and is exhausted from an exhaust port 21 provided at the other end of the heating sheet 20. The heat of the combustion gas is absorbed by the heat conductive fibers 19 when passing between the heat conductive fibers 19, and the heating sheet 20 is uniformly heated by the heat conductive fibers 19. Accordingly, the heat generated by the heat generating portion 4 is efficiently transmitted to the entire surface of the heating sheet 20. Further, the heating sheet 20 in the vicinity of the catalyst unit 22 is directly heated by the heat of catalytic combustion, and the temperature rises quickly. The back surface of the heating sheet 20 is made of fibers 2 such as highly heat-insulating fibers, and the amount of heat that escapes from the back surface is small.

[0035]
The operation of this embodiment will be described below. When the on-off knob 8 is operated to open the gas on-off valve 7, gas is ejected from the gas cylinder 6 via the gas ejection nozzle 10 and mixed with the air sucked from the air intake port 11 to become a combustible mixed gas. . When the ignition device 14 is operated in this state, the mixed gas starts flame combustion, and instantaneously raises the temperature of the combustion catalyst 13 to a temperature capable of catalytic combustion. When the catalytic combustion is thus started, the combustion gas is discharged into the heating sheet 20 from the exhaust port 18 provided in the protective cylinder 16. The combustion gas flows through the moisture absorbing fiber 37, and water vapor in the combustion gas is adsorbed by the moisture absorbing fiber 37. Further, the combustion gas also flows between the heat conductive fibers 19 having high air permeability, and is exhausted from the discharge port 21 provided at the other end of the heating sheet 20.
