Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a catalytic combustion device using heat of catalytic combustion as a heat source.

2. Description of the Related Art A conventional catalytic combustion device of this type, for example a cordless hair curler, has a structure as shown in FIG.

That is, a combustion chamber 102 is provided inside a curler part 101 that wraps and curls hair, and this combustion chamber 102
A burner 103 for ejecting combustion gas and a catalyst 1o4 for performing a catalytic exothermic reaction with this gas are provided inside, and
At the tip of the combustion chamber 102, there is provided an ignition device 105 that is operated from the outside to emit sparks using a flint, and a reversible temperature label 106 that indicates the temperature increase state of the curler part j01.
was pasted on an operation button 108 for operating a soldering iron 107.

Problems to be Solved by the Invention In the conventional structure described above, the catalyst 104 is ignited by emitting a spark from the ignition device 105, and the spark instantaneously ignites the combustion gas filling the combustion chamber 102. . The ignited gas rapidly burns (explodes) and uses its energy to raise the temperature of the catalyst 104. Therefore, burner 1
The combustion gas ejected from 03 starts catalytic combustion, and the catalytic reaction is then maintained by the combustion heat. As the curler part 101 is heated, the temperature label 106
The temperature of the product also rises by 20 seconds, and when it reaches a predetermined temperature, it changes color to notify the user that it is ready for use.

In the above structure, the catalyst 104 can be ignited by touching the heated collar part 101 with your hand to check whether it has become hot or by waiting until the temperature label 107 changes color. There was a problem in that it took time until confirmation. In addition, if it is confirmed that no ignition has occurred after waiting for a while, the ignition operation must be repeated again, making it very difficult for the user to use.

The present invention solves these conventional problems and provides a catalytic combustion device with greatly improved usability.

Means for Solving the Problems The technical means of the present invention for solving the above problems is to provide an exhaust part between the combustion chamber and the outside, and provide a piston that can freely move in and out of the combustion chamber in this exhaust part, so that the combustion chamber is constantly kept in the combustion chamber. It is stored in .

For production The technical effect is as follows.

When the ignition device is operated to ignite the catalyst and the combustion gas filling the combustion chamber is ignited, the gas rapidly expands and burns, and this expanding gas heads toward the exhaust section, causing the piston to protrude from the exhaust section. This is to make the user aware of the ignition.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings.

In Figures 1 to 3, a tank part 2 that stores liquefied combustion gas 1, which is the fuel for the cordless curler, includes a tank body 3, a tank lid 4 that closes the rear of the tank, and a liquefied combustion gas fixed to the tank lid 4. It consists of a valve 6 that allows gas 1 to be injected from the outside.

The front of the tank body 3 has a vaporization wave property (indicated by an arrow) that vaporizes the liquefied combustion gas 1 into vaporized combustion gas 6 (indicated by an arrow).
A nozzle main body 7 that includes a nozzle (not shown) for ejecting the vaporized combustion gas 6 (not shown), a valve device (not shown) for turning ON/OFF the ejection of the vaporized combustion gas 6 from the nozzle. It is closed due to.

The opening and closing of the valve device is connected to a switch 8 and a temperature control section 9. The sensitivity control section 9 is composed of an inner pipe 1Q and an outer pipe 11 having different coefficients of thermal expansion, and one end is composed of a female adjustment screw 12 and an adjustment male screw 13 fixed to each end, and is connected to the inner vibrator 1o and the outer pipe. The relative (eft) of the pipe 11 can be adjusted, and at the other end, the outer vibe 11 is fixed to the nozzle body 7, and the inner vibe 10 is inserted into the tip of the nozzle body 7, so that expansion and contraction due to differences in thermal expansion coefficients can be prevented. The difference is transmitted to the valve device of the nozzle body 7, and the temperature can be adjusted by controlling the vaporized combustion gas 6.In addition, an air intake port 14 is provided near the nozzle body 7 of the inner vibrator 10, and the vaporized combustion gas 6 is controlled. Air is taken in by the injection action of the jet of gas 6, and a mixed gas 15 of an arbitrary concentration is created.

Further, the temperature control section 9 also serves as a burner part 16 that spouts out the mixed gas 15, and the inner pipe 10 has the mixed gas 15.
The outer pipe 11 is provided with small holes 19 around the entire circumference to form a burner 18 in an arbitrary range.

The hair wrapping part 2o, which wraps and curls the hair fixed to the tank part 2 with screws, has a substantially cylindrical shape and is made of heat-resistant resin, and the inner wall widens from the tip toward the installation side of the tank part 2. A cylindrical heat-uniforming pipe 22 made of a metal with good thermal conductivity, such as aluminum, is inserted into the combustion chamber 21, which has a tapered shape and includes the temperature control section 9 to form a combustion chamber 21.

The tip of the hair wrapping part 2o is an exhaust part 23, and a piston 25 that is always urged toward the combustion chamber 21 by a spring 24 is housed in the exhaust part 23, and an electrode is attached to the tank part 2 side. It is closed by a stand 26.

In a portion corresponding to the burner 18, a combustion catalyst 22 in which platinum is supported on a non-woven material made of ceramic fibers is provided in a cylindrical shape so as to be inscribed in the heat soaking tube 22, and a coil spring is attached. 28 with a small diameter coil portion 29 and a large diameter end turn portion 30 that is in contact with the inner wall of the soaking pipe 22.
At the same time, the coil spring 28 is held by the claw portion 31 of the heat soaking knob 22 and its position is regulated.

Reference numeral 32 denotes a hair iron, which is rotated around a shaft 34 by operating an operation button 33, and is constantly biased toward the hair wrapping section 20 by a iron spring 36. 36 is a comb that can be attached and detached from the hair wrapping part 20, and 37 is a comb 3 that can be attached or removed when carried or stored.
6 is a cap that blocks heat from the hot comb 36.

The combustion catalyst 27 is ignited (in conjunction with the operation of the switch 8, the high voltage generation piezoelectric device 38 is operated, the generated high voltage is guided to the electrode 39, and the spark is blown to the outer vibrator 11. First, the mixed gas 15 ejected from the burner 18 and filled in the combustion chamber 21 is ignited.The ignited mixed gas 15 is rapidly combusted (exploded), and the expanded mixed gas 16 pushes up the piston 25 and is discharged to the outside. With,
The temperature of the combustion catalyst 27 is increased, and a catalytic combustion reaction between the supplied mixed gas 15 and the combustion catalyst 27 is started.

In the above configuration, when the switch 8 is operated without removing the cap 36, the liquefied combustion gas 1 stored in the tank portion 2 is vaporized by the vaporizer in the nozzle body T and becomes vaporized combustion gas 6, which opens the valve device 4 in the open state. It passes through and is ejected from the nozzle to the inner vibe 10.

The ejected vaporized combustion gas 6 entrains air from the air intake port 14 by injection action, becomes a mixed gas 16 with an arbitrary gas concentration, is passed through the hole 17 of the inner pipe 10, and is fed into the combustion catalyst through the small hole 19 of the outer pipe 11. The fuel is ejected toward the combustion chamber 27 , fills the combustion chamber 21 , and is discharged from the exhaust section 23 .

Next, by further operating the switch 8, the high voltage generating piezoelectric device 38 is activated, and the generated high voltage is guided to the electric wire 39 and sparks are sent toward the outer pipe 11. This spark ignites the mixed gas 15 filling the combustion chamber 21, causing rapid combustion and expansion. This expanded mixed gas 1
5 moves toward the exhaust part 23 with great force, pushing the piston 25 up from the combustion chamber 21 to the outside, and alerting the user that it will ignite. At the next moment, the piston 25 is retracted into the combustion chamber 21 by the spring 26.

Next, the combustion catalyst 27 is heated by the combustion heat of the ignited mixed gas 15, starts a catalytic combustion reaction with the supplied mixed gas 15, and transfers the combustion heat to the hair wrapping section.

Effects of the Invention As described above, the present invention provides a piston that is always energized and stored in the exhaust section so as to be able to come out and go out.
The expansion flow caused by the rapid combustion of the vaporized combustion gas causes the piston to protrude outside, making the user aware of ignition. This allows the user to immediately check whether ignition has occurred during the ignition operation, and saves the time it takes to wait for the temperature to rise. Waste can be prevented and a catalytic combustion device that is extremely easy to use can be provided.
