Description

[0001]
[Industrial application fields]
The present invention relates to a portable heating incubator having its own heat source that can be used in high altitudes, offshore, and cold regions where it is difficult to supply power and gas.
[0002]
[Prior art]
As this kind of heating incubator, a gas stove, a hood and the like using petroleum fuel as an energy source are widely used. However, the gas stove is dangerous due to an open flame, and most of the energy is released into the atmosphere, so that the heating efficiency is very poor. In addition, there was a problem that only the local area can be heated in the kaiseki.
[0003]
Therefore, heating clothes and mats with batteries and electric resistors distributed inside are considered, but the energy density per weight of the battery is low, and sufficient heat is supplied to the clothes and mats for a sufficient amount of time. It is not possible. In other words, trying to supply a sufficient amount of heat for a sufficient amount of time makes the current battery technology extremely heavy and unsuitable for carrying.
[0004]
In view of this, a method has been considered in which petroleum-based fuel having a much higher energy density than a battery or the like is heated using catalytic combustion. In this method, petroleum-based fuel is heated by catalytic combustion heat, and a liquid as a heat medium is circulated through the heated object such as clothing by this generated heat to warm the entire heated object.
[0005]
[Problems to be solved by the invention]
However, in the configuration in which the heat medium is circulated by the catalytic combustion, it is necessary to closely arrange the tubes constituting the circulation path for circulating the heat medium, which increases the amount of the heat medium in circulation and is heavy. It has a problem that it becomes less flexible.
[0006]
This invention solves the subject which such a conventional structure has, and it aims at providing the warmer for heating which is lightweight and rich in flexibility.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a heating sheet made of a heat conductive fiber, a heat insulating sheet bonded to the heating sheet, a circulation path composed of a tube enclosing a heat medium, and connected to the circulation path. A heating unit that heats the heat medium, and a pump device that circulates the heat medium in the circulation path, and the heat generating unit is constituted by a catalytic combustion device using butane gas as fuel, and the pump device includes: A heat-driven pump that operates by evaporation / condensation of the heat medium; and a structure in which the heat medium is caused to generate heat by circulating the heat medium through the circulation path. It is configured to be sandwiched between sheets.
[0008]
[Action]
The heating incubator according to the present invention realizes a heating incubator that is convenient for carrying by using a configuration in which a heat generating unit configured by a catalyst combustion device generates heat to operate a pump device and circulate a heat medium in a circulation path. A short circulation path is realized by sandwiching a circulation path composed of a tube enclosing a heat medium between a heating sheet and a heat insulating sheet made of heat conductive fibers, thereby realizing a lightweight and flexible configuration. Moreover, by using water or a mixture of water and alcohol as the heat medium, the heat medium can be properly used according to the use environment.
[0009]
In addition, the circulation path that is arranged to extend from the vicinity of the center line of the heating sheet to both left and right ends performs uniform heating from the center to the left and right, and the temperature difference between the left and right is small and uncomfortable when used as a heating mat or heating clothes. It has a heating incubator that gives no feeling of use.
[0010]
In addition, the circulation path is arranged from the lower part to the upper part of the heating sheet so that the temperature distribution gradually decreases from the lower part to the upper part. It is a warmer for heating.
[0011]
Moreover, the heat insulation sheet | seat comprised with the cushion material buffers the pressure added to a tube, It is set as the warmer for heating which maintains the flow state of the heat medium favorable and stable.
[0012]
In addition, as a circulation path constituted by a resin or rubber tube provided with an aluminum vapor deposition film on the outer wall, it is possible to prevent a heat medium from leaking and to provide a durable heating incubator.
[0013]
Further, as a circulation path in which a resin film is further provided on the outside of the aluminum vapor deposition film, the aluminum vapor deposition film is protected and is not easily damaged.
[0014]
Moreover, it is set as the warmer for heating which can use a heat medium properly according to a use environment as water or a liquid mixture of water and alcohol as a heat medium.

【Example】
Example 1
Hereinafter, a first embodiment of the heating and warming device of the present invention will be described. FIG. 1 is a cross-sectional view showing the configuration of this embodiment. The heat insulation sheet 2 comprised with the heat insulation fiber is joined to the back surface of the heating sheet 1 comprised with the heat conductive fiber. The heat conductive fibers constituting the heating sheet 1 are those in which a metal particle layer dispersed in a flexible synthetic resin binder is formed around yarns made of natural fibers or synthetic fibers, or aluminum plating with good thermal diffusion is applied. A glass yarn knitted structure or a metal fiber can be used. Moreover, as a heat insulation fiber which comprises the heat insulation sheet 2, fibers, such as glass fiber and cotton, wool, can be used, for example. A circulation path 3 in the form of a tube or a bag is attached to the surface of the heating sheet 1. A casing 7 that holds the heat generating portion 4 and the pump device 6 is attached to one end of the heating sheet 1 and the heat insulating sheet 2.
[0016]
The heat generating unit 4 communicates with the circulation path 3 and heats the heat medium 5 enclosed in the circulation path 3. As the heat generating part 4, a catalytic combustion apparatus using benzine, butane gas or the like as a fuel can be considered. The pump device 6 circulates the heat medium 5 heated by the heat generating unit 4 in the circulation path 3. As the pump device 6, a heat-driven pump, a rolling pump or the like applying evaporation / condensation of the heat medium 5 can be considered. In the present embodiment, as the heat medium 5, water or a liquid obtained by mixing 35% alcohol in water is used.
[0017]
The operation of this embodiment will be described below. When the heat generating unit 4 generates heat, the heat medium 5 circulates in the circulation path 3 by the pump action of the pump device 6. By this circulation, the heat of the heat medium 5 is transmitted from the wall surface of the circulation path 3 to the heating sheet 1. Since the heating sheet 1 is composed of heat conductive fibers, the heat of the heat medium 5 is efficiently transmitted to the entire surface of the heating sheet 1. Since the heat insulating sheet 2 is stuck on the back surface of the heating sheet 1, heat transmitted to the heating sheet 1 is prevented from being dissipated and kept warm. That is, the heat generated by the heat generating unit 4 is efficiently used for heating and heat insulation.
[0018]
At this time, in this embodiment, the heat medium 5 is water or a mixed liquid obtained by mixing 35% alcohol with water. The mixed solution has the characteristic of not freezing even in extremely cold regions. In particular, in the case of a mixed solution in which 35% alcohol is mixed with water, it does not freeze even in an extremely cold region of -20 ° C. Further, when the alcohol concentration is higher than 35%, the latent heat is lowered, and the thermal efficiency for heating the heating sheet 1 is lowered. Therefore, setting the alcohol concentration to 35% is optimal for use in such extremely cold regions. The mixed liquid of water and alcohol does not separate because water and alcohol azeotrope.
[0019]
In addition to the use in the extreme cold region, it is appropriate to use water as the heat medium 5. Water has a large latent heat and is highly heat efficient.
[0020]
As described above, according to the present embodiment, as a configuration using a circulation path in which a heat medium is sealed in a heating sheet made of a heat conductive fiber, the circulation path can be configured to be short, and as a heating incubator that is lightweight and flexible. Yes.
[0021]
Further, water or a mixed liquid of water and alcohol is used as the heat medium, so that the heat incubator can be used properly according to the use environment.
[0022]
(Example 2)
Next, a second embodiment of the present invention will be described with reference to FIG. About the whole structure of a present Example, it is the same as that of the thing demonstrated in the said FIG. In this embodiment, the circulation path 3 is arranged so as to spread from the vicinity of the center of the heating sheet to both left and right ends.
[0023]
The operation of this embodiment will be described below. When the heat generating unit 4 generates heat, the heat medium 5 circulates in the circulation path 3 by the pump action of the pump device 6. The temperature of the heat medium 5 is the highest at the outlet side of the heat generating unit 4 and is lowest when the heating sheet 1 is deprived of heat as it circulates through the heating sheet 1 and returns to the inlet side of the heat generating unit 4. . Therefore, if the circulation path 3 is arranged so as to spread evenly in the left-right direction from the center of the heating sheet 1 as in the present embodiment, the temperature distribution of the entire heating sheet 1 becomes uniform left and right. Therefore, when used as a heating mat or a heating garment, a feeling of use without a sense of incongruity is obtained because the temperature difference between the left and right is small.
[0024]
Example 3
Next, a third embodiment of the present invention will be described with reference to FIG. In this embodiment, the heat generating part 4 and the pump device 6 are arranged at the lower end of the heating sheet 1, and the circulation path 3 is arranged so as to go from the side where the heat generating part 4 and the pump device 6 are arranged toward the upper end of the heating sheet 1. It is what you are doing.
[0025]
As the above configuration, it acts as a heating and warming device that realizes head cold foot heat. The temperature distribution of the heating sheet 1 is highest at the lower end where the heat generating unit 4 and the pump device 6 are arranged, and gradually decreases toward the top. That is, when worn as a heating garment, the waist is warmer and closer to the head so that the temperature becomes lower. For this reason, it is the structure which implement | achieves the head cold foot heat, and implement | achieves the warmer for heating which can obtain a comfortable feeling of use.
[0026]
Example 4
Next, a fourth embodiment of the present invention will be described. In this embodiment, as shown in FIG. 4, the tube 8 constituting the circulation path is sewn to the heating sheet 1 with the thread 9 by a sewing method such as sewing. The tube 8 is made of resin or rubber.
[0027]
With the above-described configuration, the circulation path is unlikely to shift and acts as a heating incubator capable of obtaining a stable temperature distribution. That is, since the tube 8 is sewn to the heating sheet 1 with a thread, the tube 8 is firmly fixed. For this reason, even if it is used as a heating mat or a heating garment, a positional deviation is hardly caused and a stable temperature distribution can be obtained. In addition, by using a sewing method, it is possible to produce a variety of products such as heating clothes by simply changing the sewing pattern. For this reason, capital investment can be reduced and inexpensive heating clothes can be provided.
[0028]
(Example 5)
Next, a fifth embodiment of the present invention will be described. In this embodiment, as shown in FIG. 5, a tube made of resin or rubber constituting the circulation path 8 is knitted into the heating sheet 1.
[0029]
By adopting this configuration, the heat transfer from the circulation path 8 to the heating sheet 1 is good and acts as an energy-efficient heating incubator. That is, since the circulation path is knitted in the heating sheet 1, the contact area between the wall surface of the circulation path 8 and the heating sheet 1 can be increased. For this reason, heat transfer from the circulation path 8 to the heating sheet 1 becomes good, energy efficiency is good, fuel consumption can be saved, and a heating incubator that can be used for a long time is realized.
[0030]
(Example 6)
Next, a sixth embodiment of the present invention will be described. FIG. 6 is a cross-sectional view illustrating the configuration of this embodiment. The circulation path 8 is made of a resin or rubber tube and has a plurality of fibrous protrusions 10 on the surface. The fibrous protrusion 10 is made of a heat conductive fiber. Thus, the fibrous protrusions are knitted into the heating sheet 1 so as to entangle the heat conductive fibers constituting the heating sheet 1.
[0031]
With the above configuration, the heat transfer from the circulation path 8 to the heating sheet 1 functions as a more energy efficient heating / heater. That is, since the heat conductive fibers of the heating sheet 1 are entangled with the fibrous protrusions 10, the contact area between the circulation path 8 and the heating sheet 1 is further increased. Therefore, the heat of the circulation path 8 is transmitted well from the fibrous protrusion 10 to the heating sheet 1, and the energy efficiency is further improved. Therefore, the consumption of fuel is further reduced, and a heating incubator that can be used for a longer time is realized.
[0032]
(Example 7)
Next, a seventh embodiment of the present invention will be described. FIG. 7 is a cross-sectional view illustrating the configuration of this embodiment. In the present embodiment, the circulation path 8 is constituted by a tube made of resin or rubber, and is sandwiched between the heating sheet 1 and the heat insulating sheet 11. As this sandwich configuration, a hot melt adhesive or urethane adhesive between the heating sheet 1 and the heat insulating sheet 11 may be used, or a method of press working with a double-sided tape or the like may be considered.
[0033]
The operation of this embodiment will be described below. When the heat generating unit 4 generates heat, the heat medium 5 circulates in the circulation path 8 by the pump action of the pump device 6. Since the circulation path 8 is configured to be sandwiched between the heating sheet 1 and the heat insulating sheet 11, heat transfer to the heating sheet 1 is favorably performed. At this time, in this embodiment, since the circulation path 8 is sandwiched between the heating sheet 1 and the heat insulating sheet 11, the structure is simple, and press working can be used, so that the processing time can be shortened. Therefore, the processing cost is reduced, and an inexpensive warmer for heating can be realized.
[0034]

In this embodiment, the heat insulating sheet 12 is constituted by a cushioning material that cushions pressure applied to the tubes constituting the circulation path 8. In addition, the method of sandwiching the circulation path 8 between the heating sheet 1 and the heat insulating sheet 12 is the same as in Example 7, using press working with a resin hot-melt adhesive, urethane adhesive, double-sided tape, etc. It can be done.
[0035]
The operation of this embodiment will be described below. In this embodiment, a cushion material is used as the heat insulating sheet 12. Since the cushion material has a heat insulating effect, according to the present embodiment, it is possible to realize a warming warmer having a particularly good heat retaining effect. Further, when the cushion material is used as, for example, a heating mat, it can buffer the pressure applied to the tube constituting the circulation path 8 due to the human weight and prevent the circulation path 8 from being deformed. Therefore, the flow of the heat medium is good, and a heating incubator that maintains a stable temperature state is realized.
[0036]
Example 9
Next, a ninth embodiment of the present invention will be described. FIG. 9 is a cross-sectional view showing the configuration of this embodiment.

The heat insulating layer 13 uses the heat insulating fibers described in the first embodiment, and a configuration in which the heat insulating fibers are bonded to the heating sheet 1 or a configuration in which the heat insulating fibers are knitted on the surface of the heating sheet 1 can be considered.
[0037]
The operation of this embodiment will be described below. In this embodiment, the heat insulating layer 13 is bonded to the surface of the heating sheet 1 opposite to the heat insulating sheet 11, that is, the surface that contacts the human body. For this reason, the heating surface does not come into direct contact with the human body, and the heat is moderated by the heat insulating layer 13, thereby realizing a warming warmer that provides a mild feeling of heating.
[0038]
(Example 10)
Next, a tenth embodiment of the present invention will be described. FIG. 10 is a cross-sectional view showing the configuration of the circulation path 3 of this embodiment.
