Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot-iron device, and more particularly, to a hot-heated device made of barley-stone made mainly of barley-stone.

  The thermal acupuncture device is a device that warms the affected area in order to relieve blood circulation disorders of the limbs, relieve congestion, relieve muscle tension, etc., and has been put to practical use as an acupuncture body or a hot compress with various structures. Is intended to enhance the effect of the thermal cocoon method by utilizing the excellent far-infrared radiation property of barley rice stone.

  It is usual that the thermal apparatus using the far-infrared radiation of barley stone has a structure in which a heating source is arranged inside a bag mainly containing barley stone powder.

  The thermal acupuncture device with such a structure has the advantage that it is easy to touch the affected part because it is in the form of a flexible sheet, but the amount of far-infrared radiation radiated from the barley stone is less on the affected part. There is a disadvantage that lowers the effect of the thermal soot method.

  If you make a thermal acupuncture device by chopping raw barleystone as it is, you can use it as a spider that radiates specific far-infrared rays emitted from barleystone directly to the affected area. Can be used as a treatment aid.

  However, while the barley stone hot tub method takes a long time to heat, it has the disadvantage that it quickly cools if the external energy supply is stopped after heating.

  Such disadvantages can be overcome by filling the inside of the heating element with a latent heat material, but this heat material is often a sensible heat material mainly composed of mica powder, copper powder, alumina oxide powder, etc. Since the amount of heat storage and temperature are in a proportional relationship, it is very hot immediately after heating and is wrapped in a towel or the like.

  As a latent heat material in the heating field, a material that absorbs and releases a large amount of thermal energy by phase change is used. A phase change substance means a substance having a property of undergoing a phase transition due to a change in physical and chemical conditions. Examples of the phase transition include melting, solidification, vaporization, and condensation.

  Many types of phase change materials that cause phase transition are known, and since the melting temperatures of each material are different, usually several types are mixed and used according to the application.

  Problems with the latent heat phenomenon using phase change materials include: phase separation phenomenon in which precipitates are gradually formed when the material repeats phase transitions, and the effect of latent heat is reduced; even if the temperature drops below the melting point, Known are a supercooling phenomenon in which latent heat release stops without phase change, chemical bonding, or a corrosion phenomenon in which physical properties change with time.

  However, these problems can be solved by mixing well selected substances from various phase change materials and adjusting their properties, or adding nucleating agents and thickeners separately. It has been solved.

  Since the latent heat material widely known as such a phase change material is mainly suitable for heating, the latent heat effect is not exhibited in the temperature range of the thermal apparatus relating to the present invention.

  Therefore, it is a thermal acupuncture device that has a structure in which the radiant far-infrared radiation peculiar to barley stones can act directly on the affected area, and has a foot temperature function, a wooden pillow substitute function, an abdominal obesity relieving function, etc., and easy repair of electric heating means Therefore, it is desired to provide a barley-stone hot-water device that warms up the use site in a short time.

  It is also desired to provide a barley-stone hot-heat device having a structure in which the latent heat material stored in the hot-heat method is heated with high efficiency.

  The object of the present invention is to store a latent heat material that can maintain a heating element for a predetermined time in a temperature range that conforms to the heating method, so that it can be separated from the heating method for a long time without being continuously heated by an external heat source. It is to provide a barley-stone hot-heated device capable of infrared radiation.

  The present invention that achieves the above-described object comprises a pair of side members joined to each other so that a space is formed therein, and the space is filled with a latent heat material. It is.

  And in this invention, the outer side is coat | covered with the heat insulating material, and the storage bag by which the planar heating element was laid by the inner surface is equipped, and the said hot water apparatus can be accommodated.

  Further, the latent heat material filled in the heating element may include a magnet for promoting blood circulation.

The latent heat material accommodated in the thermal ironing apparatus of the present invention is a phase change material in which two types of sodium pyrophosphate decahydrate (Na ₄ P ₂ O ₇ · 10H ₂ O) and docosan (C ₂₂ H ₄₆ ) are mixed. 69 to 87% by weight, sodium chloride (NaCl) 10 to 15% by weight as a nucleating agent, 1 to 3% by weight of acrylic acid as a thickener, and 2 to 13% by weight of borax fertilizer as a latent heat temperature regulator What was mixed by stirring is used.

The phase change substances include calcium chloride hexahydrate (CaCl ₂ · 6H ₂ O), sodium thiosulfate pentahydrate (Na ₂ S ₂ O ₃ · 5H ₂ O), sodium carbonate decahydrate (Na _{2 CO 3 · 10H 2 O)} , sodium hydrogen phosphate dodecahydrate _{(Na 2 HPO 4 · 12H 2} O), sodium acetate trihydrate _{(CH 3 COONa · 3H 2 O} ), sodium sulfate decahydrate ( Two kinds selected from Na ₂ SO ₄ .10H ₂ O) and docosane (C ₂₂ H ₄₆ ) can be mixed and used.

  The thermal apparatus according to the present invention has a structure in which a latent heat material is accommodated in a box that provides a space separated from the outside between a heating body having a predetermined space inside and a lid that seals the heating body. May be included.

  In this case, an electric heating coil for heating the latent heat material is laid on the surface of the box.

  In the present invention having the above-described configuration, since the heating element containing barley-stone is directly brought into contact with the affected part, the amount of far-infrared radiation is significantly larger than that of other heating apparatus, so that the effect as the heating method is good.

  In addition, there is an advantage that the heated state is maintained for a predetermined time even when there is no supply of external energy due to the action of the latent heat material accommodated therein.

  In addition, the pair of heating elements joined to each other can process the contour of the surface into various forms, so that not only the illustrated disk shape, but also a wooden pillow form or the like having a curved surface with a depressed center can be easily obtained. This makes it possible to heat the neck, and the foot can be placed comfortably on the curved surface.

  Also, the curved surface fits well with the curve of the abdomen of the human body, so if you put it on the abdomen and breathe abdomen, the fat layer of the abdomen will be decomposed by the metabolic effect of far infrared radiation, Since the weight of the body holds the abdomen, the effect of reducing abdominal obesity is also excellent.

  In addition to the effects described above, the present invention has a sheet heating element as an electric heating means provided on the inner peripheral surface of the storage bag. After the service is completed, there is an advantage that the after-sales service is simplified, and the storage bag has an advantage that it can save time for heating, storing and heating.

  Moreover, since the box sealed with a cover through packing after containing the latent heat material inside is further housed inside the heating element, the latent heat material is heated by the side heating method through the box. There is an advantage that the latent heat material melted during heating is not leaked to the outside.

  The preferred embodiments of the present invention will be described in detail with reference to the drawings as follows.

  FIG. 1 is a perspective view showing a configuration of a thermal apparatus that is one embodiment of the present invention, and a pair of thermal elements 2 arranged vertically in the drawing includes barley stones, which are separated from each other across a space. They are joined together (for example, in a bag shape).

  The heating element 2 can be stored, heated and carried in a storage bag 4. As shown in FIG. 2, the internal space sandwiched between the heating elements 2 is a space filled with the latent heat material 6, and A large number of magnets 8 may be incorporated in the latent heat material 6.

  A pair of heating elements 2 that are opposed to each other with a space interposed therebetween can be bonded by a method in which a protruding portion is formed on one of the heating elements 2 and inserted into the heating element 2 for robust bonding. .

  In the present invention, the latent heat material 6 filled in the heating element 2 is obtained by mixing a phase change material, a nucleating agent, a thickener, and a latent heat temperature adjusting agent.

As a phase change substance, a mixture of sodium pyrophosphate decahydrate (Na ₄ P ₂ O ₇ · 10H ₂ O) and docosan (C ₂₂ H ₄₆ ) is suitable.

  Docosan alone as a phase change substance is heated from an initial temperature of 30 ° C. and heated and stored up to 80 ° C., and the average temperature of the entire phase change and changes in the amount of stored heat are observed. Although it progressed gradually, considerable heat storage was performed in the latent heat section of 58 to 63 ° C., and the heat storage amount at this time was measured as 68.375 Kcal / Kg.

  In addition, when sodium pyrophosphate decahydrate alone is heated and stored from an initial temperature of 40 ° C. to 90 ° C., and the average temperature of the entire phase change and changes in the amount of stored heat are observed, the initial heat storage does not proceed substantially. The heat storage amount at this time was measured as 73.25 Kcal / Kg.

  However, when the mixture of docosan and sodium pyrophosphate decahydrate was heated and stored from an initial temperature of 35 ° C to 85 ° C, the average temperature of the entire phase change and changes in the amount of stored heat were observed. At times, the heat storage of docosan, which has a low melting point, finishes increasing rapidly, while sodium pyrophosphate decahydrate stores heat at a higher temperature. The amount of heat stored at this time is usually higher by about 6% or more for sodium pyrophosphate decahydrate than docosane.

  The nucleating agent is for promoting crystal nucleation of the phase change material to prevent supercooling, and sodium chloride (NaCl) is used in this invention.

  Further, the thickener prevents supercooling in the process of melting and solidifying the phase change material, while preventing the phase separation phenomenon that occurs when melting and solidifying are repeated. In this invention, 100 wt. %, Or 99% by weight of acrylic acid, and a mixture of hexane, a surfactant, a 33% aqueous solution of sodium hydroxide (NaOH), methanol (MeOH) and epoxy 812, with the balance being about 1% by weight is used. .

  The latent heat temperature regulator is added to maintain a specific temperature range for a long time, and borax fertilizer is used in the present invention.

Phase change materials, nucleating agents, thickeners, latent heat temperature regulators as described above are
Phase change material 69-87 wt%
Nucleating agent 10-15% by weight
Thickener 1-3% by weight
Latent heat temperature regulator 2-13 wt%
Is mixed with stirring, the latent heat material 6 suitable for the present invention is obtained.

  The latent heat material 6 can be easily filled by heating at a temperature about 10 to 20 ° C. higher than the melting point of the phase change material selected when the latent heat material 6 is accommodated in the heating element 2.

  Considering such an action of the latent heat material 6, the qualitative change of the heat storage amount with respect to the heating temperature is as shown in FIG.

  In FIG. 3, □ is a graph showing the change in the heat storage amount of this invention, Δ is water as a comparative example, and ○ is a stone as a comparative example.

  As shown in FIG. 3, the latent heat material 6 employed in the present invention has a maximum heat storage amount of 30 Kcal / Kg until the temperature reaches 63 ° C., but increases rapidly to 85 Kcal / Kg near the temperature of 63 ° C. However, this phenomenon shows a characteristic of increasing slowly again at a higher temperature, but this phenomenon causes the heat accumulation of docosan to gradually progress from 20 ° C to around 63 ° C, and then suddenly increases at 63 ° C. Thus, the heat storage of docosan is completed in an instant, and the heat storage of sodium pyrophosphate decahydrate gradually appears from a higher temperature.

  Moreover, the result as shown in FIG. 4 was obtained for the latent heat effect during heat dissipation after heat storage.

  In FIG. 4, a latent heat section for maintaining a temperature of 60 ° C. for about 5 hours is formed by the latent heat material 6 of the present invention, and thereafter, the characteristic of cooling proportionally is shown.

  While the temperature of 60 ° C. in the latent heat section is maintained by the latent heat effect of docosan, the latent heat emitted from sodium pyrophosphate decahydrate is prolonged by repeating the action of reaccumulating docosan whose temperature decreases due to the diffusion of the latent heat. To be maintained over time.

  In addition, since the temperature of the latent heat section of 60 ° C. is the optimum temperature for the hot slag method using barley stone, the two phase change materials mixed as described above are the most effective latent heat materials for the slag function of barley stone. is there.

The latent heat material 6 of the present invention is not limited to two kinds of mixture of the docosan and sodium pyrophosphate decahydrate, but is a phase change material having the same characteristics as these, for example, calcium chloride hexahydrate. (CaCl ₂ · 6H ₂ O), sodium thiosulfate pentahydrate (Na ₂ S ₂ O ₃ · 5H ₂ O), sodium carbonate decahydrate (Na ₂ CO ₃ · 10H ₂ O), sodium hydrogen phosphate 12 Examples include hydrate (Na ₂ HPO ₄ · 12H ₂ O), sodium acetate trihydrate (CH ₃ COONa · 3H ₂ O), sodium sulfate decahydrate (Na ₂ SO ₄ · 10H ₂ O) and the like. One kind selected from these phase change substances can be mixed with the docosan (C ₂₂ H46) and used.

  The following table shows the melting point and the amount of latent heat per unit weight of the phase change material.

  Further, referring to FIG. 1, a cover 10 is attached to the storage bag 4 so as to be held closed by Velcro (registered trademark) 12 a and 12 b, and the storage bag is used for the cover 10. Since the internal space 14 is isolated from the outside, heat loss during heating is reduced.

  A socket 18 for inserting and connecting a plug 16 having a usual temperature control circuit is provided on the outer side of the storage bag 4, and power is applied to the electric heating device in the storage bag 4 through the socket 18. .

  On the other hand, as shown in FIG. 5, the material of the storage bag 4 is a net-like planar heating element 22 that overlaps the inner cover 20, and a heat insulating material 24 and an outer cover 26 overlap the opposite side. It has an insulating structure.

  Although not shown in the drawing, the heat insulating material 24 has a surface in contact with the planar heating element 22 as a silver foil reflecting surface so that infrared rays generated from the planar heating element 22 are reflected inside the storage bag 4. Heat loss can be further reduced.

  The planar heating element 22 is not necessarily formed in a net shape, and is provided for heating at a low temperature of 70 ° C. or less in the present invention.

  Further, as shown in FIG. 6, the net-like planar heating element 22 has a structure in which the outer surface of the fiber yarn 28 is coated with the graphite-containing resin 30, and the applied electric power flows through the graphite-containing resin 30 and its resistance. Will generate heat.

  In the present invention having the above-described configuration, the heating element 2 is heated by a simple operation of inserting the plug 16 into the socket 18 of the storing bag 4 after the simple heating element 2 is put in the storing bag 4 and the lid 10 is closed. I can do it.

  Furthermore, since the heating element 2 can also heat the latent heat material 6 in a microwave oven, and since the heating element 2 heated in this way is made of barley stone, it emits peculiar far infrared rays. .

  Therefore, it can be used by simply bringing the outer surface of the heated heating element 2 into contact with the affected area of the patient.

  Even if the heating element 2 heated by the microwave oven or the storage bag 4 is disconnected from the external heat source, the heating is continued by the action of the latent heat material 6 accommodated therein, and the heating time is maintained for a considerable time, for example, 3 to 4 at the shortest. Increase the temperature by maintaining the heated state for up to 5 hours.

  In the heating element 2, the structure for heating is not limited to the above-described embodiment, and the structure shown in FIGS.

  FIG. 7 is an exploded perspective view showing another embodiment of the hot slag apparatus relating to the present invention, in which the heating element 2 containing barleystone has a predetermined space formed therein, and a lid 40 containing another barleystone. It is configured to have an internal space that is united with and isolated from the outside.

  A box 42 is accommodated in the space formed between the heating element 2 and the lid 40. Since the box 42 is sealed by a cover 44 that is fastened with a set screw or the like, a packing 46 is inserted between the box 42 and the cover 44 in order to ensure the sealing state. Become.

  However, a groove 48 extending in a certain pattern is formed on the surface of the box 42 and the cover 44, and an electric heating coil 50 is provided so as to match the pattern of the groove 48. Inserted and laid.

  Both ends of the electric heating coil 50 are connected to a power socket 54 through a through hole 52 opened on one side of the heating element 2.

  FIG. 8 is a cross-sectional view showing a combined state of the barley stone hot-heat device having the above-described configuration, and the entrance of the box 42 containing the latent heat material 6 therein is set with a set screw or the like via the packing 46. While being sealed with the cover 44 to be tightened, the structure is shown in which the electric heating coil 50 is inserted into the groove 48 on the surface thereof and is housed inside the heating element 2 and sealed with the lid 40.

  In the configuration as described above, the electric power is applied to the electric heating coil 50 through the power socket 54 provided outside the heating element 2.

  On the other hand, the electric heating coil 50 laid on the outer surface of the box 42 and the cover 44 has a side-heat structure that heats without directly contacting the latent heat material 6, and the latent heat material 6 does not change in quality due to heat, and temperature control is easy. Thus, the latent heat material is accurately heated in the range of 50 to 80 ° C.

  In addition, the packing 46 between the box 42 and the cover 44 does not leak even if the latent heat material 6 is unexpectedly heated to 100 ° C. in order to prevent the latent heat material 6 from leaking completely.

  FIG. 9 shows an example in which a cordless power feeding method is applied to the thermal ironing apparatus of FIGS. 7 and 8.

  In this example, the thermal apparatus is mounted on a dedicated stand 56, and this stand 56 has a heating circuit 58 therein. The upper surface of the stand 56 is formed as a groove-like space 60 into which a part of the heating element 2 can be inserted, and a power socket 56 provided in the heating element 2 is inserted into the bottom of the space 60 to supply power. An electrode 62 for application is disposed at a predetermined position of the heating circuit 58, and the heating circuit 58 has the same configuration as a circuit put into practical use with a cordless iron or the like.

  According to the stand 56 having such a configuration, the heating of the thermal ironing device is simplified.

  The present invention can be applied to a hot tub apparatus. Particularly, since it is made by chopping barleystone as raw stone, the amount of far-infrared radiation is remarkably large, and it has good performance as a hot tub apparatus.

  Moreover, even if there is no external energy supply due to the action of the latent heat material housed inside, the heated state is maintained over a long period of time, so that it is possible to carry out a heating and heating method while carrying it. I can do it.

  In addition, if a pair of heating elements joined together is formed into a curved surface with a depressed center, it can also be used for a wooden pillow, thereby enabling a method of heating the neck.

  Further, since the foot can be easily placed on the curved surface, it can be used as a foot warmer.

  In addition, since the curved surface fits well with the abdomen of the human body, when placing it on the abdomen and breathing abdomen, the fat layer of the abdomen is decomposed by the metabolic effect of far-infrared radiation, while the weight of the thermal acupuncture device is It means holding the abdomen and has an excellent effect on removing abdominal obesity.

  In the present invention, since the planar heating element serving as the electric heating means is laid on the inner peripheral surface of the storage bag, it can be repaired by replacing only the storage bag at the time of failure.

  The storage bag has an advantage that it can be heated and stored in a short time without any loss of heat.
