Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As shown, the portable thermal insulation bag using a planar heating element according to the present invention is largely composed of a heating element body 100, a protective film layer 200, an inner coating 300, an outer coating 400, an external power supply connecting portion 500. do.

First, the heating element body 100 will be described. The planar heating element 110, an electrode 120, and an external drawing electrode line 130 may be formed.

The planar heating element 110 is formed by applying an adhesive to the base paper using activated carbon as a main material and graphite as a material.

The diameter of the crystallites of the activated carbon is about 20-50 μm, and the distance between the crystallites is large, while the size of the crystallites of graphite is 3.35 μm, and the distance between the crystallites is kept very small. When only activated carbon is used as the planar heating element material, the distance between crystallites is so large that the resistance is increased so that the electricity is not properly conducted, and thus the heat and electric conductivity are low, so that heat generation is not performed properly.

Therefore, when the graphite is relatively smaller than the crystallite diameter of the activated carbon and excellent in the thermal and electrical conductivity, the graphite crystallites fill the voids between the activated carbons having a large distance between the crystallites and facilitate the energization. Results in relatively improved results. The user may increase or decrease the weight ratio of graphite in accordance with the intended use and use it in various temperature ranges.

The heating element by the combination of the activated carbon and the graphite is not only inexpensive but also simple in the manufacturing process. The activated carbon may be a raw material of the activated carbon, if any of the materials that can be burned, and the raw material used for this is very expensive because it mainly uses coconut shell, lignite charcoal, bituminous charcoal, charcoal, anthracite charcoal and coal-based raw materials. Less In addition, activated carbon and graphite by themselves contain far infrared rays, anion radiation and electromagnetic shielding material, which is very beneficial to the human body.

As the pressure-sensitive adhesive that binds the activated carbon graphite, a resin adhesive is mainly used and mixed well by a mixer or the like in an appropriate weight ratio with respect to activated carbon. This is to increase the viscosity of the activated carbon graphite so that the crystallites are well bonded.

In addition, when the planar heating element 110 is mixed with a small amount of far-infrared radiation material ceramic, ocher, charcoal, natural stone powder, etc., the planar heating element 110 generates heat and a large amount of far-infrared radiation can be used as a far-infrared radiation heating element. have.

Additives such as epoxy, urethane, silicone and the like can be added to the mixed material in a weight ratio to the appropriate activated carbon to control the flexibility of the planar heating element. Then, when the material is applied to a substrate having excellent absorbency and adhesion, that is, a nonwoven fabric or fabrics and dried naturally, the planar heating element 110 is completed.

The planar heating element 110 completed as described above is cut into a predetermined size and formed in plural in parallel or in series, and the two electrodes 120 are attached to both ends of the planar heating element 110. Normally, the temperature of the object (medicine, food, etc.) to be kept warm or heated by a thermal insulation bag is about 50 to 60 ° C. The optimal electrode width is about one third the width of the planar heating element. However, the user can adjust the width according to the temperature range to be used.

The electrode 120 may use a metal material having various conductivity, but it is preferable to process and attach aluminum in the form of a thin film, that is, aluminum foil. Because aluminum thin film is cheaper than other metals, it has high electric conductivity compared to area and light weight. In addition, since the aluminum thin film does not generate electromagnetic waves, which is a problem of conventional electrodes, it is very preferable to use it as an electrode in the present invention.

The electrode 120 is formed to be in contact with the planar heating element 110 and the external drawing electrode line 130 to be connected to the external power source. The position where the outer lead electrode line 130 is in contact with the electrode 120 is suitable for the central portion in the longitudinal direction of the electrode 120 for fast transfer of power to the planar heating element 110 and uniform temperature rise. Of course, the user may attach a plurality of external lead-out electrode lines at different positions according to the use of the thermal insulation bag. The external lead-out electrode line 130 may be formed of a heat resistant wire having a thickness of 0.3 mm or less in order to increase the adhesion with the heating element body protective film layer 200 which will be described later.

In addition, it is preferable that the temperature control unit 131 is further formed on the external lead electrode line 130. It is a structure having various functions, and it can be made into a structure having various temperature setting functions by installing thermostat and temperature sensor with temperature control function, but it can be manufactured at low cost, can be easily used even when outdoor activities, and is convenient to carry. It is also possible to use a temperature bimetal to control the heat generation temperature. That is, the temperature control unit 131 operates a temperature sensor with the external drawing electrode wire 130 drawn from the heating element body 100 so as to maintain a heat generating heat function at low cost without installing an additional device for installing a thermostat. By installing a bimetal can be installed a temperature control unit 131 to maintain a constant temperature at all times.

That is, when the external lead-out electrode line 130 and the metal line of a different expansion coefficient are joined to each other and the horizontal one becomes low at a low temperature, the external lead-out electrode line 130 is opened by bending to a side having a smaller expansion coefficient (another type of metal wire). No current flows to maintain a constant temperature.

As described above, when the heating element body 100 including the planar heating element 110, the electrode 120, and the external drawing electrode line 130 is completed, it is preferable to further form the reflecting plate 140 on the lower surface of the heating element body. The reflector plate 140 is made of an insulator, and reflects heat from the planar heating element 110 to prevent loss to the outside and to be transmitted only to the inside.

After forming the heating element body 100, the upper and lower surfaces of the heating element body 100 are accommodated to protect the heating element body 100 and to insulate the electrode 120. ) Is preferable.

The protective film layer 200 is a thermosetting film having heat resistance, gas permeability, and moisture resistance (PE (polyethylene), PP (polypropylene), foam PS sheet, PC (polycarbonate), PA (polyamide), PET (polyester) ), PU (polyurethane), fluororesin film can be used, and laminating machine is used for perfect adhesion.

Next, the inner coating 300 formed on the upper surface of the protective film layer 200 will be described.

The inner coating 300 is in the form of a bag consisting of a coupling means 320 is formed on the inlet 310 and seals the inlet 310 on one side. The coupling means 320 is preferably used because the shape of the zipper satisfies the simplicity and convenience of the coupling, but may be in the form of a button or a zipper lock.

The inner coating 300 is to be coupled to the outer coating 400 to be described later, due to which the planar heating element 110 formed between the inner coating 300 and the outer coating 400 transfers heat from both sides of the bag Because it is stored internally, it has the advantage of reducing heat loss and warming up quickly.

Next, the outer coating 400 is formed on the lower surface of the protective film layer 200 and is coupled with the inner coating 300 along the end thereof, so that the protection is between the inner coating 300 and the outer coating 400. The film layer 200 and the heating element body 100 are accommodated. Since the inner coating 300 is a bag shape, the outer coating 400 is also coupled along its end to form a bag shape.

In addition, the outer coating 400 has a through hole 410 for drawing the outer lead electrode line 130 to the outside. In addition, in order to facilitate the connection of a variety of power in consideration of external activities, the cigar jack storage bag 420 and the battery storage bag 430 is installed on the outer coating 400 side to conveniently store the battery and the cigar jack.

The inner coating 300 and the outer coating 400, because the outer protective layer of the existing container using a solid steel or plastics, there is no flexibility to carry and complicated manufacturing process, but the present invention is a PU (polyurethane) film It is coated with material and takes a flexible form. Other films such as PE, PP, PVC, PET, melamine and artificial leather can be used. This makes it possible to make the most of the advantages that can be folded and folded or folded of the planar heating element 110 as a heat source.

Next, the external power connection unit 500 will be described.

The external power connection unit 500 is connected to the external drawing electrode line 130 or the temperature control unit 131 and is formed of various terminals for receiving external power. It is recommended that the external power supply use a voltage of 12V or more that can normally perform the heat generation function. Although it can be used at a voltage of 12V or less, a considerable time is required for the thermal insulation bag of the present invention to perform the heat generation function.

In addition, the external power connection unit (500) is installed in the cigar jack connection terminal in case of using for the vehicle, adopting the DC plug to facilitate the connection with the DC power supply device in the home or office, and the small battery during outdoor activities The battery input terminal or the cigar jack terminal can be used to replace the power source.When using AC power for home use, the bimetal function may be damaged due to overload during direct connection. Encourage the use of a thermostat.

The operation of the present invention by the above configuration is as follows.

First, an object for warming or warming to a predetermined temperature is inserted into the bag having the planar heating element formed on both sides by opening the coupling means. At this time, the subject may correspond to food, drink, cans, medicine bags such as retort pouches. Since the planar heating element 110 is very flexible, it can be freely crimped in a bag or the like.

In the case of using the vehicle, the cigar jack of the vehicle is connected to the cigar jack connection terminal and heated to an appropriate temperature. When the proper temperature is reached, it is possible to maintain a constant temperature at all times by the bimetal having different expansion coefficients from the external drawing electrode line 130. Thus, while both surfaces of the object are heated, the heat is transferred only to the inside without heat being lost to the outside by the reflector plate 140, so that excellent heat retention and warming function can be simultaneously performed.

The present invention by the above configuration is easy to carry in the form of a pocket, the surface heating element is heated on both sides is excellent in heat generating heat function, and there is an effect of free storage and installation due to the flexibility of the coating.

In addition, the heating element main body not only radiates far infrared rays and negative ions, but also has an electromagnetic shielding function, which is beneficial to the human body, and can be used in various places such as vehicles, offices, outdoor activities, and general households, so that there is no restriction on the use place, and the present invention. According to according to the production of thermal insulation bag can be manufactured at a low cost has the effect of reducing the production cost.
