For example, it includes a heating element having a positive temperature coefficient (PTC) characteristic, a heating element composed of a polymer and a conductive material, a conductive ink-based heating element, etc., but since this is already a known technique, details are referred to. do not do.

  The portable heating device shown in FIGS. 1 to 4 is a portable heating device of a type that winds a flat heating element 10 and stores it in a storage container 20. FIG. 1 shows a state in which the planar heating element 10 is pulled out from the storage container 20 and used as a heating device. FIG. 2 shows a state in which the planar heating element 10 is wound up and stored in the storage container 20. Show. FIG. 3 shows another embodiment. FIG. 4 shows a detailed cross-sectional view of the storage state.

  FIG. 1 shows a state in which the planar heating element 10 is pulled out from the storage container 20 and used as a heating device. The planar heating element 10 maintains the expanded state of the planar heating element 10 by the stand member 60. The details of the planar heating element 10 are shown in FIG. 6, and a heating surface is formed by printing a heating material 11 such as heating ink on the insulating flexible base film 13, and the heating material 11 and the heating material 11 are heated. Electrodes 12, 12, and 12 are arranged at an appropriate interval with respect to the surface, and an insulating flexible protective film 14 is attached thereon or an insulating ink is printed thereon to form a flexible flat heating element 10. Is configured. The base film 13 is generally a plastic film, but may be made of paper or cloth, but a material having flexibility (a material that can be bent or rolled is suitable) and an insulating property are suitable. ing. The electrodes 12, 12, and 12 may be made of any material such as silver paste printing or copper foil bonding, and any technique may be applied. The electrodes 12 may be arranged at an appropriate interval, and the number of the electrodes 12 is three in FIG. 6, but may be two or four. Further, the arrangement direction of the electrodes 12 may be vertical or horizontal. If the number of electrodes decreases, the area of the heat generating material 11 through which current flows is increased, and the heat dissipation area increases, but the resistance for energization increases. The electrodes 12, 12 and 12 are appropriately provided with wirings 17 and 17 for supplying current from a power source (not shown) for energization.

  The planar heating element 10 includes support poles 15 and 16 on both sides (left and right ends in FIG. 6), and both ends of the planar heating element 10 are supported by these. One support pole 15 is disposed so as to be rotatable in the vicinity of the central portion in the storage container 20, and the other support pole 16 is disposed so as to be drawn out of the storage container 20. Wirings 17 and 17 from the electrodes 12, 12 and 12 toward the power source are drawn into one support pole 15 (preferably a support pole disposed in the storage container 20) of the planar heating element 10. (Not shown).

  The storage container 20 includes a cylindrical container body 21, a container lid body 22, and a pedestal portion 23. In the pedestal portion 23, power supply control means 24 (FIG. 4) for controlling the temperature of the heating device of the present invention is provided. The power supply means 24 preferably incorporates a transformer when a household AC 100V is used as a power supply. If a transformer with variable voltage is used, the temperature of the heating device can be adjusted. By this power control means 24, 100V alternating current from an outlet 27 inserted into a power source (not shown) is transformed to an appropriate voltage and supplied. The power supply control means 24 can use a transformer or the like that is already known as a known technique, and is not the gist of the present invention.

  In the heating device of the present embodiment, one support pole 15 is disposed in the vicinity of the center portion in the storage container 20, and the flexible planar heating element 10 needs to be wound around the support pole 15. For this reason, it is preferable that the support pole 15 is configured to be rotatable, and the power is supplied from the support pole 15. Therefore, in this embodiment, several inventions are attached.

  In FIG. 4, the cross-sectional view in the state which wound up the flexible planar heating element 10 of the heating apparatus of a present Example in the storage container 20 is shown in detail. As is clear from this, one support pole 15 is erected firmly by the leg member 30 with respect to the pedestal portion 23. The leg member 30 is a member for allowing the support pole 15 to stand upright in the vicinity of the center of the pedestal portion 23, and the leg member 30 is provided to be rotatable with respect to the pedestal portion 23. The leg member 30 forms a boss portion 31 provided with a support pole insertion hole in order to erect the lower end portion of the support pole 15. The power supply cord 25 to the planar heating element 10 is led into the support pole 15 from the center of rotation. Since the planar heating element 10 is rotated a plurality of times and wound by 360 ° or more, the power supply cord 25 needs to have a margin 28 corresponding to the number of windings, and is accommodated in the take-up reel 32. It is the composition which becomes. As a result, when the leg member 30 rotates and the planar heating element 10 is wound around the support pole 15 at the center and stored in the storage container 20, a margin 29 corresponding to the number of windings is provided. The winding is tightened and wound around the leg member 30 serving as a reel, and the support pole 16 of the planar heating element 10 is pulled out of the storage container 20 and widened. Is relaxed. The reverse direction may be used to kick or loosen the winding of the margin 29. Further, it is not always necessary to have a configuration in which the marginal amount of cord 29 is wound in a reel shape, and even if the planar heating element 10 is wound around the support pole 16 a plurality of times or extended, Any configuration can be used as long as a margin is maintained in the cord.

  The power supply to the power control means 24 is achieved by inserting the outlet 27 into the power supply and turning on the power switch 26. The cord 28 at that time is wound around the pedestal 23 by the conventional technique. Is possible. This is a well-known technique using a cord winding technique such as a vacuum cleaner or an iron.

  The container lid 22 is formed with a vertically long slit 19 for pulling out the planar heating element 10 from the inside of the storage container 20 to the outside, and the support pole 16 is stored even after the planar heating element 10 is wound up. It remains outside the container 20. When the portable heating device of the present invention is carried, the flat heating element 10 is closed after being accommodated in the take-up storage container 20, but since the convex part 29 is formed on the container lid 22, the convex part 29, it is possible to stably support the other support pole 16 remaining outside the storage container 20 after being wound up.

By fitting these convex portions 64, 64 and the concave portions, the rotation of the first member 61 and the second member 62 is fixed in a constant state. This state is shown in FIG. In FIG. 5A, the angle between the first member 61 and the second member 62 is θ, and this θ is 180 °, that is, the first member 61 and the second member. It is needless to wait for explanation that 62 may be linear. When the first member 61 and the second member 62 are folded for storage, the protrusions 64, 64 are not fitted into the recesses and bent due to the elasticity of the material.

  Openings 64 and 65 for inserting the lower ends of the support poles 15 and 16 are formed at the ends of the first member 61 and the second member 62, respectively. This fit is preferably a little tight. Further, since the first member 61 side is stabilized by the pedestal portion 23, the bottom surface of the first member 61 may be flat, but by providing the heel portion 66 on the bottom surface of the second member 61. The standing of the support pole 16 can be stabilized.
