Description

  The present invention facilitates sweating by forcibly injecting a large amount of heat into a human body through a heat storage body by indirect heating in a short time at a low temperature such as the temperature of a bath in a lying position. It relates to a perspiration apparatus.

  Sauna baths are used as a means to promote physical circulation and improve physical condition with a great deal of sweating. This sauna bath heats the indoor air to a high temperature and gives a large amount of heat to the user in a short time, and in association with this, a large amount of sweat is caused in a short time to promote blood circulation. It is generally used as a way to give a refreshing feeling after taking a sauna bath.

  As this sauna bath, a high temperature sauna that heats indoor air to a high temperature of 90 ° C. to 110 ° C. and a mist sauna that heats the air to around 45 ° C. to 50 ° C. are known.

  As for a large-sized sauna apparatus, a low-temperature sauna apparatus has been proposed in which a heating apparatus that heats indoor air and emits far-infrared rays is provided on the ceiling of a sauna room formed around a chair (Patent Document 1).

In addition, as a sauna apparatus that is made as small as a general household bath, a heating apparatus is proposed in which a heating device is disposed on the ceiling of the bathroom and the air in the bathroom is circulated (Patent Document 2) .

The far-infrared device of any sauna bath is a gentle infrared irradiation, and the human body cannot receive a large amount of heat. The high temperature sauna has a temperature of about 100 ° C. and a humidity of about 1%, and its discomfort index (sweat index) is about 128. Here, as one measure of the ease of sweating, a general discomfort index is defined as a “sweat index”. The discomfort index is obtained by the following equation, where T is temperature (C) and humidity is H (%).
Discomfort index = 0.81T + 0.01H (0.99T-14.3) +46.3

  The sweating index and body feeling are classified as comfortable (index: 65 to 70), hot and sweaty (index: 80 to 85), and hot and unbearable (index: 85 or more). Usually, the temperature that a human body feels comfortably is about 23 ° C. and the humidity is about 50%, and its sweat index is about 69.

  Since the mist sauna has a temperature of about 50 ° C. and a humidity of 100%, its sweat index is about 122. Both the high temperature sauna and the mist sauna have a sweat index much higher than 85, and it is hot and unbearable. In other words, in order to promote a large amount of sweat from the human body, the sweat index must be 100 or more.

  In addition, as a material having a temperature lower than that of the mist sauna, a bedrock bath used for lying on a rock heated to about 40 ° C. is known. However, the bedrock bath is performed in an environment of temperature and humidity (over 80%), and this environment is suitable for the propagation of bacteria and fungi. Etc. sometimes bred. Therefore, it had to be disinfected and dried regularly. And the sweating is about 99, and it is hot and sweats.

  Furthermore, in an esthetic salon that performs whole body beauty, an electric heating blanket made of towel cloth is laid on a bed, a human body is laid on the bed, and the whole body is covered with a blanket and heated to perform various beauty methods. The bed used for this purpose is water-resistant, and the human body is warmed by electric heat with a blanket wrapped around the human body. This electric heating blanket has a built-in linear heater, and there are problems such as a user being burned by a heater having a high temperature of 80 ° C. or higher, leakage electromagnetic waves, and electric shock.

  In any case, the sauna apparatus as a sweating means is large and cannot be easily installed in a general household. For example, sleeping bags have been proposed that lay a sleeping bag on the floor and lay a human body in the sleeping bag to warm the body (Patent Documents 3 and 4).

Japanese Patent No. 2808368 Utility model No. 3029324 JP 2001-46204 A JP-A-9-182653

  For example, when aiming for a large amount of sweat in a short time such as within 30 minutes, the full-fledged sauna bath described in Patent Document 1 and Patent Document 2 is effective. However, in a general sauna bath, the human body is heated by contact with high-temperature air heated to 90 ° C. to 100 ° C., so the time that can withstand this high temperature is very short even for young men. Women who can withstand such high temperatures are limited to young and energetic people. Further, the sauna bath takes about 15 minutes for continuous bathing, and the amount of heat received by the human body in this short time is a few tens of kcal (about 50 kcal).

The sauna bath needs a large amount of heating energy because it must heat all of the air filled in the sauna room as described above. However, since only the air in contact with the human body gives heat to the human body, the efficiency of heat conduction to the human body is extremely low. Assuming that the average molecular weight of this air is 29 and the air contributing to the application of heat in the vicinity of the human body is 1 m ³ , the heat quantity of the air is as small as about 23 kcal.

  The temperature difference between the hot air and the human body is about 70 ° C., and it is difficult to breathe, and depending on the person, there is a risk of heat stroke or dehydration. Resting for about a minute and hydration were necessary.

  Further, the invention described in Patent Document 3 is a sleeping bag in which a batting is interposed between a top sheet and a back sheet, and the batting is composed of an exothermic batting made of a moisture-absorbing and moisture-absorbing and exothermic fiber material, and exothermicity. It has a two-layer structure of batting made of synthetic fibers that it does not have, and the environment inside the sleeping bag is kept warm and dry due to the hygroscopicity and heat build-up of the batting made of moisture absorbing / releasing and water absorbing heat generating fiber material It is. Therefore, this sleeping bag does not have the function and effect of promoting perspiration, but is merely a bedding.

  Furthermore, the sleeping bag described in Patent Document 4 is mainly intended to enhance the heat retaining effect and guarantee sleep, and is not intended for sweating.

  Japanese Patent Laid-Open No. 2001-70463 (reference) provides a concrete layer as a sensible heat storage body, lays a ceramic ball thereon, and heats the concrete layer with a heating medium, This is a device that radiates infrared rays through and warms the body. Moreover, the effect about a large amount of sweat cannot be expected so much.

  Furthermore, sand baths are used as sweating materials in a sleeping posture. In this sand bath, a hollow shaped like a human body is formed on a sand bed heated to about 50 ° C., and a user who wears a yukata or the like is lying down on the sand floor, and the entire body excluding the user's head is 60 ° C. It is used in such a state that it is covered with sand heated to a certain extent and the whole body is completely covered with sand.

  By the way, the sand bath requires a “sandbox” that is wide enough to lie down over the entire body, and requires a large amount of sand to cover the entire body, and its heating equipment and the like increase in size. It was used in bathing facilities, hot springs, and sightseeing spots. In addition, the amount of sand required per user is about 50 kg in order for the sand to adhere to the human body, and the weight of the sand is heavy and the specific heat of the sand is 0.2 kcal / kg. -Since it is ° C., the heat difference is about 190 kcal at a temperature difference of 20 ° C., which is a small amount of heat. Furthermore, since the temperature difference between the human body and sand is about 20 ° C or higher, a large amount of sweat is secreted, and the human body temperature rises, so it cannot be used for more than 15 minutes continuously and has enough rest. And sufficient hydration is also needed. And the amount of heat that the human body receives from the sand in 15 minutes is only about 100 kcal.

  And since it must be 20 ° C or higher than the human body, it requires a lot of energy necessary for heating, and the sand emits heat only by sensible heat and cools down. I had to keep heating. Moreover, since the sand adheres to the body and becomes dirty, it takes time and effort to rinse the body and wash away the sand.

  Moreover, the humidity is about 90% in the sand, and the sand bath sweat index is about 118.

  Use a conventional mud bath, etc. if you can apply a full body cosmetology while giving a refreshing sensation with a dry posture and an easy posture like sleeping on a futon, sleeping bag, or bed. Compared with esthetic methods, the whole body beauty method can be performed by a much simpler method.

  Furthermore, in a sleeping position (recumbent posture), a large amount of sweating can occur, the weight can be reduced with the sweating, a refreshing feeling remains after use, and the body becomes warmed up, Furthermore, if it can be stored in a smaller size, it is possible to produce an unprecedented device that can obtain effects and conveniences not found in conventional sleeping bags and sauna devices.

  In view of the problems of the above-mentioned various conventional techniques, the present invention has a form that is similar to a futon or sleeping bag, which is a normal bedding, and has a much more comfortable heat receiving feeling compared to a conventional sleeping bag type sweating device. While feeling, it is less than 45 degrees Celsius or a little higher bath temperature, or a temperature close to body temperature, but it can inject a large amount of heat into the human body and promote a large amount of sweat in a short time, never before An object of the present invention is to provide a sweating method and apparatus.

  Moreover, the following structure can be considered as a modification of this invention.

A. When the device according to the present invention is used, the weight of the heat storage mat received on the chest surface of the human body is quite heavy, and some elderly people and slim users may feel painful. In such a situation, a means for reducing the weight of the heat storage mat may be provided as appropriate.
Specifically, as shown in FIG. 11, auxiliary lifting means 40 for reducing the weight of the upper heat storage mat among the heat storage mats constituting the heating space is provided.

As described above, the heat storage mat is released using the reflection by placing a sheet of aluminum foil on the surface or a separate sheet on the lower side of the synthetic resin bag constituting the heat generating sheet. The amount of heat to be emitted can be radiated toward the human body. And by grounding this aluminum foil, an electrical failure should be prevented. It is also possible to reduce leakage electromagnetic waves radiated from the heat generating sheet.

A. (Rapid heat application)
The present invention does not directly transfer electric heat to the human body like an electric blanket or electric carpet. Instead, the amount of heat generated by electric heat is once transferred to a heat storage mat containing a latent heat storage agent to store heat mainly by latent heat. In addition, the “latent heat and sensible heat” are injected into the user in a state of being in contact with or substantially in contact with the heat storage mat, thereby giving the heat necessary for sweating.

B. (Heating the human body at a temperature similar to body temperature)
Moreover, the temperature of the latent heat type heat storage agent is a temperature near the body temperature, and is a temperature that belongs to a considerably low temperature as compared with a normal heating appliance, and uses a temperature comparable to a hot bath.
Despite the large amount of heat given to the human body from the heat storage agent, the user feels only as hot as a hot bath and feels like sleeping while using the device.

C. (Heating of the human body that heats bones)
The heat transfer from the heat storage agent to the human body needs to be performed in as short a time as possible. In particular, the radiant heat from the heat storage agent is suitable to have a wavelength at which calcium phosphate that constitutes bone (90% calcium phosphate and 10% calcium carbonate) absorbs heat.

D. (Cold bone heating)
Usually, the radiant heat generated from the heat storage agent is not often 10 μm, which is the absorption wavelength of calcium phosphate. Therefore, in order to match the wavelength of the radiant heat generated from the heat storage mat to the wavelength, it is preferable to use a ceramic that emits infrared rays having the absorption wavelength at the operating temperature (for example, about 45 ° C.).
Specifically, it is preferable to use a finely powdered ceramic (mainly composed of titanium oxide, aluminum oxide or the like). The ceramic fine particles are selected so that they float in the molten heat storage agent and do not settle in a short time.

E. (A lot of sweating)
A large amount of heat is directly transferred to the human body from the lower heat storage mat that is substantially in close contact with the user's human body, and infrared rays of about 10 μm, which is the maximum absorption wavelength of calcium phosphate, which is the main component of bone, are irradiated. Because of this construction, a rapid sweating action comparable to that of a sauna bath that conducts heat from the surface like a convection oven can be obtained. Further, since breathing can be performed in a normal room, it is possible to prevent the respiratory system from being damaged by high-temperature dry air.
With the ceramic, the user can be sufficiently warmed from the core of the body and the body temperature rises by about 1.5 to 2 ° C., and can feel warm and warm for more than 8 hours even after use. The user h feels a very pleasant heat in about 10 minutes from the start of use, and a tasteless sweat comes out from the whole body in about 15 minutes.

F. (Anti-obesity effect)
There are brown adipocytes around the bones of the human body, and these brown adipocytes have energy from white adipocytes (so-called obesity-causing cells) and use this as heat energy to increase body temperature. Are known.
The sweating apparatus according to the present invention is considered to warm bones, activate brown adipocytes existing around the bones, and promote energy combustion of white adipocytes. Therefore, it is thought that it will not rebound if it stops like diet therapy (diet) or exercise (exercise).
Therefore, the sweating apparatus according to the present invention allows the user to effectively burn white fat cells that are the cause of obesity simply by lying down, and continuously exerts a slimming effect superior to intense exercise It is considered possible. And it is thought that health is improved and it contributes greatly to non-illness.

G. (Hypothermic effect of hypothermia)
It is known that a person (35 degrees C or less) whose body temperature is lower than a healthy body (36-37 degreeC), such as a woman, raises body temperature, the enzyme in a body activates and immunity improves.
However, by continuously using the perspiration apparatus of the present invention, a number of experimental examples have been obtained that the immunity of the person with low body temperature is improved and the cold is not caught.

(Structure of sweating device)
FIG. 1 is a side view of a futon type or sleeping bag type sweating device (S) according to the present invention. In the figure, reference numeral 1 denotes an underlay sheet made of a synthetic resin foam sheet, which blocks heat transfer with the floor surface. A long heat generating sheet 2 is bent into a U shape on the underlay sheet 1, and a user's human body 4 is laid inside the sheet. A space for accommodating the user's human body 4 is a “heating space”.

  A lower heat storage mat 5 is disposed on the lower surface of the human body 4 in the heat generating sheet 2, and an upper heat storage mat 6 is disposed on the upper surface of the human body 4, that is, on the upper side of the heat generating sheet 2a. ing. Then, the sweat absorbing layer 7 made of a thick towel cloth is accommodated inside the heat generating sheet 2 bent into the U shape in a folded state in the U shape.

  The sweat absorbing layer 7 is formed in a sleeping bag shape so as to wrap the human body 4 from the shoulder to the toes. Further, in the case of a towel towel having a thick sweat absorbing layer 7, it may be difficult to perform processing such as washing, drying or disinfection. In addition, the sweat absorbing layer 7 can be entirely or partially worn by wearing a shape like a large cylindrical garment.

  In any case, it wraps around the human body 4 from the shoulder to the body and the toes, keeps the heels warm as if they were in a warm room, absorbs sweating comfortably, and does not let the human body 4 feel moisture Those having properties are preferred.

  When the apparatus according to the present invention is used, the human body 4 may remain naked, but it is preferable to wear simple clothing that does not bind the body, such as a yukata, as much as possible. In many cases, when the lower heat storage mat 5 and the upper heat storage mat 6 of the sweating device S are exposed and exposed to the air, wasteful heat dissipation is large, so that the entire sweating device (S) is thin as shown in FIG. It is recommended to hang a top cover 8 such as a futon or blanket.

“Back heat storage mat 5 and chest heat storage mat 6” are important members as components of the present invention, and have a heat storage capacity capable of sufficiently storing heat before using this sweating device (S). Preferably, it is 2095 kj (500 kcal) per 29 kg .

  And the second requirement is that it is extremely soft but stretched like a hot water bath or a slightly hot liquid in a rubber balloon. It is an “elastic repulsion body” or “heat storage elastic body” that has a soft touch like the skin.

  The third requirement is that “elastic resilience bodies 5a, 6a” or “heat storage elastic bodies 5a, 6a” are flexible as described above, but they are destroyed even when an impact force is applied to the extent that the user loses weight. It has the durability that does not.

  The shape of the heat storage elastic body is most preferably a sheet shape that is an aggregate of heat storage elastic bodies in consideration of the simplicity and handling of the manufacturing process, but a spherical object filled with a heat storage agent is used. You may connect with connection members, such as a string-like thing, and you may form in a sheet form.

  FIG. 2 is a cross-sectional view showing a part of the back surface or chest heat storage mats 5 and 6, and FIG. 3 is a plan view thereof.

  As the film F constituting the heat storage mats 5 and 6, as shown in FIG. 4, a laminated film having a three-layer structure or a laminated film having a two-layer structure including an underlayer f1, an intermediate layer f2, and a surface layer f3 is used. . In the case of a laminated film having a three-layer structure, the underlayer f1 is a stretched film of polyethylene (thermal adhesive layer) having a thickness of about 200 μm and a polyamide-based synthetic fiber (nylon) having a thickness of 15 μm, and has strength and gas barrier properties. It is Further, the surface layer f3 is a stretched nylon film having a thickness of 15 μm and has strength and gas barrier properties. In the case of a two-layer laminated film, the lower layer is a polyethylene film having a thickness of 200 μm, and the upper layer is a stretched nylon film having a thickness of 15 μm.

  The film F for the heat storage mats 5 and 6 is not limited to the composite structure, but may be a single layer structure as long as it has electrical, thermal stability and safety properties. Can do.

  In the present invention, if the film F is hard, the feeling of use is irritating. Therefore, it is preferable to provide flexibility by forming appropriate wrinkles and fine grooves by embossing or the like.

  As shown in FIG. 3, the film F having the above-described structure is formed in a bag body B having an opening at one end by welding the periphery and the bottom part by combining the upper and lower two sheets. Bags b1 and b2 are formed in parallel by welding the intermediate part in the direction.

  Next, the heat storage agent h heated so as to be in a liquid or gel form is filled into the two bags b1 and b2. Then, the two parallel bag bodies b1 and b2 are crossed at predetermined intervals in the length direction and divided into small bags as shown in FIG. 5, and a plurality of heat storage elastic bodies 5a are arranged in two rows. .

  The reason why the thermal storage elastic body 5a is divided into sachets as shown in FIG. 2 is to limit the movement of the gel-type thermal storage agent h and increase the internal pressure when a pressing force such as body weight is applied. This is because an elastic force is exerted as a repulsive force, and the generation of this elastic force gives a comfortable sensation as if a human body 4 is lying on the balloon when it lies on it.

(Heat generation sheet)
The exothermic sheet is a product of the Misato Co., Ltd. (Kamiwada 521-18, Satte City, Saitama Prefecture), the product name “Plaheat”, and has an automatic temperature control function (PTC action). The width is 250, 300, 500 mm. Is 60 to 70 W / m, and the latter is 90 W / m.

(Heat storage mat)
The thermal storage elastic bodies 5a and 6a constituting the thermal storage mats 5 and 6 have a tendency that when the volume is larger than a certain size, the elastic force is lowered, and when the volume is smaller, the thermal storage elastic bodies 5a and 6a are not only hard but also tend to be separated from the welded portion. The lower heat storage mat 5 is for heating the human body 4 at a low temperature of about the body temperature by releasing the heat storage while substantially contacting the human body 4 and loading its weight.

  FIG. 5 shows the relationship between the heat generating sheet 2 and the heat storage mats 5, 6. These heat storage mats 5, 6 are always arranged in a stacked state with the heat generating sheet 2, and the area of the heat generating sheet 2 is greater. It is slightly larger than the heat storage mats 5 and 6 and is designed to be longer. In this embodiment, two heat storage mats 5 are stacked to increase elasticity and deformability (deforms along the shape of the human body) and heat storage amount.

  The laminated state of the heat generating sheet 2 and the upper heat storage mat 6 is not limited to the above configuration, and the heat generating mat 6 may be disposed on the upper side of the heat generating sheet 2 as shown in FIG. Thus, it can arrange | position on the lower side, or can arrange | position on both the upper side and the lower side of the heat generating sheet 2 and can maintain heat conductivity and favorable.

  FIG. 6 is a perspective view showing the cloth bags 31 and 32 for storing the heat storage mats 5 and 6 and the cloth bag 20 for storing the heat generating sheet 2, and a partition 10b is formed in the longitudinal direction at the center of the thick cloth bag 10a. The back heat storage mat 5 is inserted into each cloth bag 10a in the laminated state. Further, the thin cloth bag 10c is also formed with a partition 10d in the longitudinal direction, and is configured to insert the chest heat storage mat 6 into each bag 10c.

  The thick cloth bag 10a and the thin cloth bag 10c are configured to be adhered in close contact with the cloth bag 20 containing the heat generating sheet 2 by connecting means such as Velcro (registered trademark) not shown. In addition, a magic tape (registered trademark) (not shown) is provided at the opening / closing opening 10f of the cloth bags 10a, 10c, and 20 so that the heat storage mats 5 and 6 and the heat generating sheet 2 can be taken in and out.

  In addition, as shown in FIG. 9, the outer side of the film 2a, which is an insulating bag for the heat generating sheet 2, is wrapped with aluminum foil Al so as to be electrically safe by taking heat conductivity and grounding as necessary.

  FIG. 7 is a cross-sectional view showing a state in which the heat generating sheet 2 is accommodated in a cloth cover bag 20, and normally the heat generating sheet 2 is accommodated in a synthetic resin film cover 2a and electrically insulated. In the present invention, it is further accommodated in the cover bag 20 for use.

  FIG. 8 shows that the two heat generating sheets 2 are accommodated in the cover bag 20 shown in FIG. 7, and the lower heat storage mats 5 and 5 are respectively placed on the storage portions 10a of the bag 31 shown in FIG. The state which has arrange | positioned the stored heat storage agent containing bag is shown.

  FIG. 8 shows an apparatus in which the lower heat storage mats 5 and 5 are combined with the two heat generating sheets 2 and 2, respectively. However, if the width of the heat generating sheet 2 is doubled, one heat generating sheet is generated. A heat storage unit can be configured by combining a plurality of heat storage mats 5 with respect to the sheet.

[Schematic dimensions of sweating device components]
The schematic dimensions of an actual sweating device are exemplified as follows.
A. Thermal storage mat cloth cover a) Back thermal storage mat bag: length: 1620 mm, width: 250 × 2
b) Chest heat storage mat bag: length: 1400 mm, width: 250 × 2
B. Fabric cover for flat electrothermal heating sheet Length: 3050mm, width: 500mm
C. Attachment of Exothermic Sheet Cover and Thermal Storage Mat Cloth Cover The rear thermal storage mat bag and the chest thermal storage mat bag are connected so as to be formed at an interval of 30 mm. The interval of 30 mm is for forming a hole for changing the position of the planar electrothermal heating sheet from the lower side to the upper side.
D. Example of amount of heat storage agent used a) Amount of heat storage agent (sodium sulfate 10 hydrate) of the back heat storage mat 5: 25 kg
b) Amount of heat storage agent (sodium sulfate decahydrate) of the chest heat storage mat 6: 4 kg
Total amount of heat storage agent: 29 kg (total heat storage amount: about 5112 kj (1220 kal)
The heat storage amount of about 5112 kj is larger than 2095 kj (500 kcl) defined in claim 5, but 2095 kj is a value obtained by theoretical calculation, and 5112 kj is the actual value. It is a value obtained by measuring the calorific value in this device, and varies greatly depending on the configuration and dimensions of the device.
Moreover, it is preferable that the amount of stored heat can be sufficiently heated while the temperature is low enough to allow the user to sweat a lot during use of the device and to cause sleepiness.

(Types of heat storage agent)
The heat storage agent h may be designed in a manner that depends on the age of the user, the preference of the heating temperature, and the time of use, and its melting temperature and solidification temperature change.

In the case of a normal physical condition, a material having a property of storing and releasing heat with a phase change at a temperature difference of 25 ° C. to 45 ° C. is preferable. In the present invention, at a temperature difference of 28 ° C. to 32 ° C. Mainly used is “Shozo”, which has the property of storing or releasing heat with phase change. The crystal mirabilite is sodium sulfate decahydrate (Na ₂ SO ₄ · 10H ₂ O).

  If the heat storage agent is a simple substance, it may occur that the planned endotherm does not meet the purpose of heat dissipation. Based on this, add the third component to this to adjust the melting point and freezing point. It is good.

  As an example, sodium chloride aqueous solution can be slightly added to sodium sulfate decahydrate to adjust to have the desired characteristics.

As described above, the heat storage agent must have a temperature range between the melting point and the freezing point that does not adversely affect the human body, and has the property of warming the “bone” as much as possible. In the case of the above-mentioned mirabilite , there is a heat storage amount of 5112 kj (1220 kal) at 29 kg, which is optimal for this kind of low-temperature heating.

  In the embodiment of the present invention, the heat storage agent is used at a temperature at which the heat storage agent is melted, that is, 45 ° C., which is a heat storage completion state, and the temperature difference from the human body is only about 10 ° C. It has an overwhelming amount of heat that is more than 4 times that of 50 kg of sand) and more than 36 times that of a sauna bath. In addition, since the thermal storage agent at the time of a use start is 45 degreeC, and the sensible heat at this time is also included, the thermal storage amount has exceeded 1000 kcal well. And most of the amount of heat is received by the human body by direct conduction when the heat storage mat is substantially in close contact with the human body.

As the other heat storage agent, normal paraffin (paraffin-based latent heat storage agent) can be used. There are various types of paraffin-based latent heat storage agents ranging from low to high solidification temperature (melting temperature) depending on the number of carbon chains, and heat storage agents suitable for the user's preference and heating temperature can be used. In addition, the sodium thiosulfate pentahydrate _{(Na 2 S 2 O 3 ·} 5H 2 O, melting point 48 ° C.), sodium acetate trihydrate _{(CH 3 COONa · 3H 2 O} , melting point 58 ° C.), calcium chloride 6 There are a water salt (CaCl · 6H ₂ O), a sodium phosphate 12 hydrate (NaHPO ₄ · 12H ₂ O), a nickel nitrate trihydrate (Ni (NO ₃ ) ₂ · 3H ₂ O), a sodium chloride aqueous solution, and the like.

  However, from the experience that the inventor used for 30 years, even if it leaks out, the operating temperature is low and it does not burn, it is nontoxic and nonflammable, and the amount of heat storage, The sodium sulfate decahydrate is preferred.

(Use of ceramic)
The heat storage agent has a characteristic of absorbing predetermined latent heat and sensible heat in accordance with the phase change and releasing the absorbed latent heat, but in order to increase the effect of the present invention, it simply stores the human body. It is necessary not only to warm by using the heat radiation of the agent, but also to warm from the core of the body and make the whole body feel warm.

  Therefore, in the present invention, a ceramic fine powder having a property of emitting infrared rays having a wavelength (around 10 μm) that is easily absorbed by the user's bone (especially the spine) at the use temperature (about 45 ° C.) is mixed in the heat storage agent. And use it.

Specifically, by using alumina (Al ₂ O ₃ ) # 500 and # 8000, radiant heat having an optimum wavelength at the operating temperature can be generated to effectively warm the human body. In addition, fine powders such as titanium oxide (TiO ₂ : titania) and calcium carbonate (CaCO ₃ ) can be used.

  The amount of the ceramic fine powder added can be sufficiently exhibited when the amount is about 1 to 1.5% with respect to the amount of the heat storage agent by weight%.

  When the ceramic fine powder is added to the heat storage agent, it gradually precipitates with time, resulting in a problem that the radiation efficiency of far infrared rays decreases. In order to solve this problem, it is possible to avoid the precipitation phenomenon of the ceramic fine powder by adding about 1% of the fine water-absorbent resin powder to the heat storage agent.

(Effective use of heat generated from heat storage mat)
In particular, the amount of heat released from the lower (back side) heat storage mat 5 is considerably large. Further, the heat transfer direction and the direction of radiation are the front and back surfaces of the heat storage mat 5. Therefore, the amount of heat released from the back surface is a loss of heating of the human body. Therefore, as shown in FIG. 9, the aluminum foil Al is placed between the film 2 a wrapping the heat generating sheet 2 and the bag 10 so as to be used as a mirror for heat reflection, thereby improving the thermal efficiency. Can do.

(How to use sweating device)
When using the sweating device according to the present invention, the heat storage mats 5 and 6 are heated by energizing them about 2 to 3 hours before use, and the heat storage agent h accommodated in the heat storage mats 5 and 6 is sufficient. The latent heat is stored and dissolved (32 ° C.), and the sensible heat is stored by further heating (about 45 ° C.). And when using the apparatus which concerns on this invention, energization is set to "OFF" and safety is ensured, and it uses so that the human body 4 may be heated only with the calorie | heat amount stored in the said heat storage mats 5 and 6. FIG. At this time, due to the direct heat conduction from the heat storage mats 5 and 6 substantially in contact with the human body 4 and the far infrared rays (mainly about 10 μm wavelength) emitted from the heat storage mats 5 and 6, the human body Warm from outside and inside.

(Need for a timer)
A timer for turning off the energization of the heat generating sheet 2 is important. The amount of heat stored in the heat storage mats 5 and 6 can sufficiently warm the human body for about 1 hour, and some users may want to use it for longer than 1 hour. In addition, the temperature of the heat storage agent gradually decreases during use. Therefore, according to the user's preference, the timer can be operated to reheat the heat storage mats 5 and 6 for a predetermined time (for example, in increments of 15 minutes) so that they can be “cooked”.

  In order to avoid such a risk, a circuit with a “basic energization time” timer (usually about 1 hour of the time until the heat storage of the heat storage agent is completed) and an additional timer that starts the “additional energization time” is provided. It is good to install.

  This additional timer corresponds to a so-called “cooking” of the bathtub, and it is preferable to configure the circuit so that the current can be energized for a maximum of one hour in 15-minute increments, for example.

  This timer, for example, turns on one LED in 15 minutes with a single button press, turns on a second LED of a different color with a second press, and so on. If it is configured so that the sweating device S can be operated safely, and the timer is operated with “under confirmation” of the user, the heating time of the human body is adjusted according to the physique and physical condition of the user. Thus, the device can be safely operated.

(Device operating temperature)
The sweating apparatus according to the present invention is used at a temperature of 45 ° C. and a humidity of about 60%, and its sweat index is about 101, and can sweat enough, but the temperature difference from body temperature is It is characterized by being relatively small.

(Feeling of use)
A) The sweating apparatus according to the present invention feels a very pleasant heat and has an unprecedented experience. In addition, after about 10 minutes from the start of use, the whole body feels hot and after about 15 minutes, sweat erupts from the whole body and face.

B) The sweating apparatus according to the present invention has a pleasant heat unlike entering a sauna, and after about 30 minutes, the salty sweat is not so much, and it becomes a dry and tasteless sweat. The kite also seems to sweat when running around 12km from the starting point in the marathon.
Therefore, sweat like a sauna bath that contains a large amount of water and ions (smooth and salty) does not continue to erupt from the beginning to the end. Does not feel like a sauna bath.

C) In the case of a man in his mid 40's who used the sweating apparatus according to the present invention once or twice a week for about 1 hour each for about 3 months, the body weight which was initially 68.5 kg was 61. Reduced to 6kg. And the circulation of the whole body is improved, a sense of stability is obtained mentally, and it becomes a “calm comfort”.
In particular, the sweating device according to the present invention is characterized by the fact that there is no exercise such as tight gymnastic exercises, and anyone can use it for a long time, while reading, listening to music, or watching TV dramas. Can do. Even more surprising is that after using the sweating apparatus according to the present invention, there is no rebounding of body weight compared to other weight loss methods.

  In addition, insomnia, coldness, constipation, and women in the early 70s who have trouble waking up, after using the sweating device according to the present invention, the insomnia is cured and the coldness is felt. The overall physical condition was improved to maintain a pleasant warmth for a long time (about 3 hours) after use, improved bowel movement, and improved blood flow.

F) As described above, according to the sweating apparatus of the present invention, a large amount of sweat is promoted in a lying position in a lying position, and while it is simply in a lying position, weight loss can be achieved, insomnia can be cured, and constipation may occur. There are many examples of improving physical condition such as healing.
In particular, metabolic syndrome has recently become a problem, and companies are responsible for the health management of employees. The device of the present invention can also exert great power in such health management. Is. Furthermore, it can contribute to non-disease management for maintaining a healthy body.

  F) Although the temperature difference from the human body is relatively small, an overwhelming amount of heat that has not been possible in the past can be imparted to the human body. In other words, the temperature difference with the human body is within 15 ° C, the amount of heat stored by latent heat and sensible heat exceeds 1000 kcal, and since it is used slowly over 1 hour to 1 and a half hours, A large amount of heat can be received.

  G) Since the heat storage mat gently holds the user's body like a water bed, it can be used with a comfortable sleeping comfort. Moreover, since it deform | transforms and closely_contact | adheres according to the curve and unevenness | corrugation of a body, thermal efficiency increases further.
