Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating garment that can be used in high altitudes, at sea, and in cold regions where it is difficult to supply power and gas.

[0002]

2. Description of the Related Art As a conventional heating garment, it has been a long time ago.
As disclosed in Japanese Patent Application Laid-Open No. 8-60708, there is known an apparatus in which a bag portion capable of accommodating a platinum-catalyzed combustion body is provided between a front cloth and a back cloth. However, in such a heating garment, there is a problem that it is not possible to heat a wide area in the garment only by heating the local area where the cairo is arranged.

[0003] Therefore, a device disclosed in Japanese Patent Application Laid-Open No. Sho 61-266604 has been proposed. Referring to FIG. 7, a heat source storage unit 71 for storing a heating element and a cooling element in a part of clothing is provided with a heat-insulating material or a reflective material so as to reduce heat release. A heat exchange unit 72 is provided, which is joined to the heat exchange material 71 by a heat conductive material or the like,
The heat exchanging section 72 and a heat releasing section 74 disposed at a desired position are connected by a heat conducting section 73 made of a vinyl pipe or the like that conducts heat by flowing a heat medium such as air.

Japanese Patent Application Laid-Open No. Hei 4-347450 discloses that a gaseous fuel is catalytically burned, a liquid such as water is heated by the heat, and an appropriate temperature liquid is circulated through clothes by a heat pump. A warmer is disclosed.

[0005]

However, the one disclosed in Japanese Patent Application Laid-Open No. Sho 61-266604 describes that
Since the heat exchanged in the heat exchanging section 72 is caused to flow through the heat conducting section 73 such as a thin vinyl pipe to exchange heat in the heat emitting section 74, the heat transfer efficiency is poor, and the heat emitting section 74 is disposed. However, there is a problem that it is difficult to sufficiently heat the desired portion. Therefore, there is a problem that a sufficient heating effect cannot be obtained unless the amount of generated heat is increased, such as disposing a combustion type heat source in the heat source storage 71.

In the device disclosed in Japanese Patent Application Laid-Open No. 4-347450, a heat medium such as water is circulated from a portable device body into a garment through a tube, so that the garment is heavy and flexible. In addition, there is a problem that it is difficult to incorporate the apparatus main body into clothes, which is inconvenient.

[0007] In view of this, it has been considered that the combustion type heat source unit is mounted on clothes in order to reduce the weight and size of the heat source unit. In this case, air necessary for combustion must be sucked and exhausted. If air is taken in and out of clothes, incomplete combustion may occur, such as when a short circuit occurs between the intake and exhaust and a sufficient amount of air is not drawn in, and the fuel gas is released as it is to the human body. May be sucked.

Further, when air is taken in and out of the clothes, dew condensation occurs due to a difference in the amount of saturated water vapor between the exhaust air temperature and the outside air temperature, and the condensed water flowing to the outer surface of the clothes freezes to damage the fibers of the clothes. There is a danger that the intake and exhaust ports may be blocked by arms, etc., and dust such as cotton and dust may enter through the intake port and burn in the combustion section, or block the intake port to prevent incomplete combustion. There is a problem such as a possibility of causing.

In view of the above problems, the present invention can prevent incomplete combustion while attaching a combustion-type heat source to clothes, does not have a possibility of blocking the intake / exhaust port, and produces dew condensation and dust. It is an object of the present invention to provide a heating garment that can prevent the invasion of the garbage.

[0010]

A heating garment according to the present invention comprises a heat source unit using combustion heat as a heat source, a fuel tank storing fuel to be supplied to the heat source unit, a control unit for controlling combustion of the heat source unit,
An air inlet for taking in outside air into the heat source portion, and an air outlet for discharging exhaust air from the heat source portion, wherein at least one of the air inlet and the air outlet is opened to the outer surface of the clothing. One or both of the mouths are opened to the outer surface of the clothes, so that the intake and exhaust are performed reliably without a short circuit between the exhaust and the intake, and the amount of air necessary for combustion can be secured and incomplete combustion may occur. Can be eliminated, and the inside of the clothes can be heated safely and reliably.

In addition, if an intake pipe communicating the heat source section with the intake port and an exhaust pipe communicating the heat source section with the exhaust port are provided, the intake port is separated from the heat source section at a position convenient for intake and exhaust. And an exhaust port can be provided, so that intake and exhaust can be reliably performed.

Further, when the exhaust port is disposed above the heat source, there is a possibility that water vapor contained in the exhaust will condense at the exhaust port and wet the surroundings, or may be frozen by contact with cold outside air, thereby damaging the fibers of clothes. Can be eliminated.

[0013] Further, when the intake port and / or the exhaust port opened to the outer surface of the garment are arranged near the back side portion of the side of the garment, even if a person wearing the garment performs any operation. In addition, there is no possibility that the intake port and the exhaust port are blocked, and safe combustion can be ensured.

Further, when a filter is provided at the intake port, it is possible to prevent cotton dust, dust and the like from entering the combustion portion into the air supplied from the intake port, thereby preventing incomplete combustion due to these. .

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a heating garment according to the present invention will be described below with reference to FIGS.

In FIG. 1, reference numeral 1 denotes a garment, and a heating device 4 is mounted between the outer material 2 and the lining 3 of the garment. Heating device 4
As shown in FIG. 1 and FIG.
And a fuel tank unit 6 storing fuel to be supplied to the heat source unit 5.
A control unit 7 having a dry cell as a control power supply and a control circuit to control the combustion of the heat source unit 5; an intake and exhaust unit 8 for performing intake and exhaust on the heat source unit 5; A tank 6 and a mounting band 9 to which a control unit 7 is mounted are provided. As shown in FIG. 3, a wide cut is formed in the lower part of the lining 3 of the garment 1 so as to be openable and closable with the fastener 3 a. 3 is inserted and arranged in the space between the two, and the right part of the mounting band 9 is joined to the back surface of the outer fabric 2 by the hook-and-loop fastener 10, and the suction / exhaust portion 8 is provided on the back surface of the lining 3 (the surface on the outer fabric 2 side). By holding at 11, the heating device 4 is attached to the clothing 1. In addition, the hook-and-loop fasteners 10 and 11
It is needless to say that other suitable detachable attaching / detaching means or attaching means may be used instead. Further, as shown in FIG. 2, the fuel tank unit 6 and the control unit 7 may be individually stored in storage pockets (not shown) provided in the clothing 1 without being mounted on the mounting band 9. .

As shown in FIG. 4, the heat source 5 injects fuel into the main body housing 12 concentrically toward the ejector 14, the ejector 14 connected to the lower portion of the combustion cylinder 13, and the ejector 14. A nozzle 15, an intake passage 16 having one end open on one side of the lower space of the ejector 14 and the other end opening on the outer surface of the main body housing 12, and one end connected to the upper end of the combustion cylinder 13 and the other end connected to the main body housing And an exhaust passage 17 which is open to the outer surface of the exhaust pipe 12. A combustion catalyst 18 and an ignition means 19 are disposed in the combustion cylinder 13. Further, a temperature detecting means 20 such as a thermistor for detecting the temperature of the catalyst 18 is provided.

At the lower end and the upper end of the main body housing 12, an inflow opening 21 for introducing air in the lower part of the garment 1 into the main body housing 12 to heat it and flow it out toward the upper part of the garment 1 is formed. An opening 22 is formed, and fins are formed on the outer surface of the combustion cylinder 13 to increase the efficiency of heat exchange with air flowing upward in the main body housing 12 and to enhance the efficiency of heat transfer with the heat conduction band 41 described later. 23 are protruded.

The nozzle 15 is, as shown in FIGS.
The fuel tank 6 is connected to the fuel tank 6 by a fuel supply pipe 24.
The openings of the intake passage 16 and the exhaust passage 17 on the outer surface of the main body housing 12 are connected to the intake / exhaust section 8 via an intake pipe 25 and an exhaust pipe 26. Further, the ignition means 19 and the temperature detection means 20 are connected to the control unit 7 through a control signal line 27.

As the catalyst 18, various combustion catalysts can be used. A metal substrate formed by forming a thin plate of an iron-chromium-aluminum alloy into a corrugated shape is allowed to stand in air at a high temperature. By depositing aluminum on the surface of this metal substrate, applying γ-alumina to it and baking at high temperature, a catalyst support having a large surface area is formed, and this is immersed in a solution in which platinum is dissolved and baking at high temperature to obtain platinum. Those in which a catalyst is precipitated are preferred.

As shown in FIG. 5, a gas tank 29 filled with a propane gas, a butane gas, or a mixture thereof is set in a fuel case 28 of the fuel tank section 6. It is configured to supply a required amount of gas to the apparatus.

The fuel tank 6 is provided with an operation switch 31 so that all necessary operations such as ON / OFF operation and replacement of the gas cylinder 29 are performed by the fuel tank 6. The operation switch 31 and the control valve 30 are connected to the control unit 7 via a control signal line (not shown) and a control signal line 27 arranged in parallel with the fuel supply pipe 24.

As shown in FIG. 3, the intake / exhaust section 8 is
Is formed of a substantially rectangular box-shaped intake / exhaust box 32 having a large number of intake ports 33 and exhaust ports 34 formed on one side of the outer surface of the garment 1, and one side thereof faces an opening 35 formed on the outer material 2 of the garment 1. And held by the holding means 11. The opening 35 is sewn with a mesh material 35a and is covered so as to allow ventilation. A filter 40 for removing cotton dust and dust flowing into the intake pipe 25 together with the outside air is disposed inside the intake / exhaust box 32.

The mounting belt 9 is made of a fiber material having heat insulation and flexibility, such as a felt cloth, and its inner surface (the inner surface of the garment) receives heat from the heat source 5 as shown in FIG. A heat conduction band 41 for transmitting the heat to the entire surface is provided. As the heat conduction band 41, a natural fiber or a synthetic fiber in which a metal particle layer formed by dispersing metal particles in a flexible synthetic resin binder and a metal particle layer formed around a woven fabric of an aluminum-plated glass fiber having good heat diffusion property is formed. Woven fabrics, woven fabrics of metal fibers such as copper and non-metallic fibers such as polyester, woven fabrics made of carbon fiber, etc. can be preferably used, but a graphite sheet obtained by graphitizing a polymer film is used. Since the heat conductivity in the plane direction is extremely high and the heat conductivity in the direction perpendicular to the plane is low, the heat of the heat source 5 spreads uniformly over the entire surface of the heat conduction band 41, and the heat source 5 is spread over the entire surface. It is optimal because it can be heated with the same effect as provided, and can be suitably applied to clothing because it is flexible and has a specific gravity equal to that of water and is very light.

In the above configuration, when the operation switch 31 is turned on, the control valve 30 is opened and gas is ejected from the nozzle 15 through the fuel supply pipe 24, and the ejector 14 passes through the intake port 33 of the intake / exhaust section 8 through the intake pipe 25. Then, air is sucked through the intake passage 16 and the air-fuel mixture is supplied to the combustion cylinder 13. By operating the ignition means 19 in this state, the mixed gas starts flame combustion and instantaneously raises the temperature of the catalyst 18 to a temperature at which catalytic combustion can be performed.

In this way, catalytic combustion is performed in the combustion cylinder 13, and the exhaust gas is discharged from the intake / exhaust section 8 to the outside of the clothing 1 through the exhaust passage 17 and the exhaust pipe 26. Thereafter, the control unit 7 controls the gas supply amount by controlling the opening of the control valve 30 in accordance with the detection signal from the temperature detection means 20, and performs combustion so that the catalyst 18 is maintained at a predetermined temperature appropriately set. Control is performed.

In this way, the heat generated by the catalytic combustion is transferred from the combustion cylinder 13 to the fins 23 to warm the air flowing in the space between the outer fabric 2 and the lining 3 of the garment 1 through the main body housing 12. Is transmitted to the heat conduction band 41 via the main body housing 12, and is efficiently transmitted to the entire surface of the heat conduction band 41. Further, the mounting band 9 having a high heat insulating property is disposed outside the heat conduction band 41, and the amount of heat escaping to the outside is small. Thus, a person wearing the clothing 1 equipped with the heating device 4 has a heat conduction band 41 around the waist.
Is heated by the heat transmitted to the entire surface of the back of the garment 1 and flows through the space between the outer material 2 and the lining 3 of the garment 1 through the main body housing 12 of the heat source unit 5 toward the entire back. Is warmed. Further, the warm air rising from the back flows down the surrounding space between the outer material 2 and the lining 3 of the garment 1, circulates the entire garment 1 by warming each part and returning to the lower part of the heat source unit 5, The entire clothing 1 becomes warm.

By the way, when the intake and exhaust accompanying the combustion in the heat source unit 5 is performed in the garment 1 without providing the intake and exhaust unit 8,
During combustion, a short circuit may occur between intake and exhaust, resulting in incomplete combustion due to insufficient intake, and furthermore, combustion may not be possible if the amount of supplied oxygen is low, and the fuel gas concentration High exhaust gas and raw fuel gas are released into the clothing 1. Therefore, when the heat source part 5 by combustion is arranged in the garment 1, it is necessary to prevent a short circuit between the intake air and the exhaust air in the garment 1 in order to ensure complete combustion. In the present embodiment, the intake port 33 and the exhaust port 3
4 is formed with the opening 3 on the outer surface of the garment 1.
5, so that air intake and exhaust are performed with the outside air,
Smooth intake and exhaust are performed to ensure stable combustion.

The exhaust gas generated by combustion contains a large amount of moisture, and the temperature of the exhaust gas decreases while passing through the exhaust pipe 26. Condensation will form. When the opening 35 of the garment 1 is located below the heat source 5, the moisture generated by the condensation passes through the exhaust pipe 26, and passes through the garment 1 through the intake / exhaust unit 8.
It is released outside. Here, when the outside air is below the freezing point, the moisture released outside the clothing 1 freezes on the outer surface of the clothing 1 and damages the fibers of the clothing 1. On the other hand, in the present embodiment, since the intake / exhaust section 8 is disposed above the heat source section 5, the condensed moisture returns to the heat source section 5 and is evaporated, so that such a problem can be solved.

When the opening 35 of the garment 1 is closed by an arm or the like, the air required for combustion cannot be sucked from the outside, the amount of oxygen required for combustion becomes insufficient, and the combustion stops. However, in the present embodiment, it is found that the back side part of the side part is never blocked even when the person wearing the garment 1 performs any operation, and the opening 35 is formed in the part. Since it is arranged, it is possible to prevent accidentally stopping combustion due to insufficient intake. The opening 35 may be arranged on the chest or side of the garment 1. In that case, the opening 35 can be easily opened because the person who wears the cover 35 is relatively less likely to be closed and can easily be visually checked by the person who is wearing it when it is closed.

When the cotton dust, dust, etc. of the clothes 1 are mixed during the intake air, there is a possibility that the air clogs the intake pipe 25 or the like and obstructs the intake air. Although the flammable gas is ignited and burns and adheres to the combustion cylinder portion 13 to reduce its durability. In the present embodiment, since the filter 40 is provided in the intake port 33, dust,
Stable combustion can be ensured for a long time by preventing dust and the like from being mixed.

In the above embodiment, the intake / exhaust box 32 having the intake port 33 and the exhaust port 34 is disposed near the back side of the side of the garment 1, and the intake pipe 25 and the exhaust pipe 26 are provided.
Although the example connected to the heat source unit 5 through the heat source unit 5 is shown, it is not always necessary to connect the intake port 33 and the exhaust port 34 to the heat source unit 5 through the intake pipe 25 and the exhaust pipe 26. In the case where it is clear that the heat source unit 5 is used in a state where there is no possibility of the central portion being blocked, as shown in FIG. 6, the intake port 43 and the exhaust port 44 are opened directly on the outer surface side of the heat source unit 5,
Openings 45 and 46 may be formed in the outer fabric 2 on the back side of the garment 1 so as to face the intake port 43 and the exhaust port 44 and to be permeable to mesh fabric, respectively.

In the above embodiment, the intake ports 33, 4
3 and the exhaust ports 34 and 44 are both opened on the outer surface of the garment 1, but only one of them, preferably the exhaust port 3
4 and 44 are opened on the outer surface of the clothing 1;
May be opened in the space between the outer material 2 and the lining 3 or the inside of the lining 3. In this case, there is a possibility that the intake resistance may increase somewhat, but there is no possibility that a short circuit will occur between the intake and exhaust.
The risk of incomplete combustion is low.

Further, in the above-described embodiment, an example is shown in which the heating device 4 is housed and arranged in the space between the outer material 2 and the lining 3 of the garment 1, but the invention is not necessarily limited to this. The whole or a part of the heating device 4 may be provided in the heater.
