Description

  The present invention relates to a so-called sauna bath used for physical therapy.

  The sauna room is made of wood and the base is made of pine or poplar. Formally, a sauna stone is baked with a fire of fire, a small amount of water is applied to the heated stone, and the temperature and humidity in the sauna room are adjusted with the steam, but a simple method of burning the stone with electric heat is taken There is also.

The sauna heats indoor air to a high temperature, and can be said to be an extremely reduced number of water particles in the steam bath. Even withstand. Usually, saunas are called dry saunas because they are used at high temperatures (100 to 110 ° C.) and low humidity (10% or less), and sauna baths are said to be appropriate for about 5 to 15 minutes.
However, the sauna room of the dry sauna is hot and low in humidity, so that depending on the person, the water inside the nostrils evaporates and feels hot and may make you feel sick. If wet towels are used to prevent this, there is a risk of burns, and when the room humidity is increased by generating mist, the original function of the sauna cannot be exhibited.

On the other hand, hot water showers are known as mist saunas, and saunas that generate mists using ultrasonic humidifiers as steam saunas, but they can be generated using ultrasonic humidifiers as well as simple hot water showers. There is a problem of feeling damp discomfort in the atmosphere formed by mist.

Japanese Examined Patent Publication No. 3-49468 (page 2, column 4, line 1 to line 7)

  The problem to be solved is that the hot water and low humidity in a dry sauna are difficult to breathe, and in a mist sauna that is just a shower of hot water, the inside of the sauna is hot and low in humidity. The steam sauna containing mist generated by an ultrasonic humidifier may feel uncomfortable due to a damp feeling.

  The sauna according to the present invention is characterized in that the above disadvantages of the dry sauna and the mist sauna are eliminated, and the room is sweated in a low-temperature and high-humidity atmosphere, thereby enabling a comfortable sauna bath.

  As mentioned above, the sauna room is always filled with negative ion-containing air that is activated at all times, and sweating is possible at a low temperature that is slightly higher than the body temperature. There is no burden on the organs. Air containing a large amount of negative ions has a positive effect on human health and mental health, and has the effect of removing bacteria, dust, and odors. Can be kept in.

  According to the present invention, when the room temperature is used at a temperature slightly lower than the body temperature, it is possible to stay in the room for a long time and to enjoy relaxation in a clean atmosphere containing negative ions.

  It has been known for a long time that air ions greatly affect human health. Air ions are generated by the ionization of crust radioactive material, cosmic rays from the atmosphere, ultraviolet rays, gas oxidation by heat, ionization by lightning discharge, and when the water drops break up in the air Generated by ionization. The charging phenomenon that accompanies water droplet splitting during precipitation or near waterfalls is called the Leonard effect or waterfall effect, and ions generated in the air are negative regardless of the charge of the water droplets. It is an ion (see Meteorological and Electrical Engineering Hisao Naoyama and Kei Kawano, Iwanami Shoten, p. 27).

  Regarding the influence of positive ions and negative ions on the human body caused by ionization of air, it is generally said that positive ions excite nerves and negative ions calm down nerves. For this reason, waterfalls, rivers, coasts, etc. are in the air. The generated negative ions are thought to make you feel better.

  Recent studies have shown that negative ions have a dust removal effect, disinfection effect, deodorization and gas component removal effect, humidity control effect, and antistatic effect, and have a positive effect on the growth of animals and plants. Attention has been paid to ions.

For the work of air ions, see Weekly Medical World Report No. 1007 Separate Printing P4 There is a detailed report to Medical Times Co., Ltd. This is shown in Table 1.

  In the present invention, an ion dissociation process functionally performed by an ion dissociation mechanism, a droplet activation process and a gas molecule ionization process performed by a droplet activation and gas molecule ionization mechanism, and a gas-liquid separation mechanism Although negative ions are generated by sequentially performing the gas-liquid separation process to be performed, each process is not necessarily clearly distinguishable. The technical meaning of each process will be described below.

(1) Ion dissociation process The ion dissociation process is a process for dissociating water in short. When high energy is given to the liquid (water), the water (H ₂ O) is ionized as H ₂ O → H ⁺ + (OH) ⁻ , and a charge double layer is formed in the liquid as shown in FIG. In the liquid surface in contact with air, oriented dipoles are arranged with negative ions facing outward, and more negative ions are attracted near the liquid surface. If the liquid is mechanically split into small droplets by any method, the net charge of the droplet becomes negative, and the positive ions are left in the liquid as large particles or neutralized through grounding. (Refer to Electrostatic Handbook, P104, edited by Electrostatic Society, Ohm).

  High energy as ion dissociation treatment can be imparted mechanically, electrically, electromagnetically, optically, or by irradiation with radiation. The splitting of water droplets is a mechanical ion dissociation process, but if the ion dissociation process is performed prior to the splitting, the amount of water molecule-added negative ions generated can be increased 2 to 5 times.

(2) Liquid droplet activation process The liquid droplet activation process is a process of accelerating by applying high energy to ion-dissociated liquid particles. Since high energy is imparted to the liquid particles, ion dissociation is further promoted, splitting proceeds, aerodynamic transportation is performed at high speed, and the droplet interface is activated.

  In the present invention, a high-speed air current is used for accelerating the droplets, and centrifugal force and Coriolis force are applied to activate the interface in a short distance and in a short time. A method of applying centrifugal force to the droplet particles is to make the droplet particles rotate. Coriolis force is one of the apparent forces that act on moving objects in a rotating coordinate system. If the angular velocity of rotation is ω and the mass and velocity of the mass point are m and v, the Coriolis force is given by 2m × ω × v. Since the Coriolis force due to the rotation of the earth works in the opposite direction in the northern and southern hemispheres and to the right in the direction of travel in the northern hemisphere, the Coriolis force acts in the direction of the angular velocity vector of the earth's rotation when the droplet turns. Set the turning direction. By effectively applying the Coriolis force, it is possible to obtain energy when a raindrop falls several hundred meters at a distance of several centimeters.

  The activation of the interface means that the dipole is oriented by the dipole moment of water to form a dipole double layer, and negative charges are released when the negative ions are arranged outward.

H ⁺ : OH ⁻ in the infinitely fine droplets attracts each other by van der Waals force, but receives strong centrifugal force (mrω2) and Coriolis force (2 mvω), and H ⁺ and OH ⁻ , The mass difference (H ⁺ = 1, OH ⁻ = 17) facilitates the orientation of OH ⁻ toward the outside, and discharges a negative charge when the dipole is oriented.

(3) Ionization treatment of gas molecules The ionization treatment of gas molecules is a treatment that is inevitably performed after the droplet activation treatment.

When the droplets get infinitely small while moving with high energy and the dipoles are oriented on the surface of the water droplets, they ionize oxygen (O ₂ ) molecules present at the gas (air) side interface. , ^O _- 2 · a _(H 2 O) minus that appears by n (negative) ions molecular groups (see supra electrostatic Handbook P317). This negative (negative) ion molecule group is called a water molecule-added negative ion. As a result, the water droplets obtain an equal amount of positive charge to the ions generated during the splitting (see Meteorology and Electrochemistry, p. 27 above).

(4) Gas-liquid separation process A gas-liquid separation process is a process which isolate | separates the air containing a water molecule addition negative ion from a droplet. Gas-liquid separation needs to be performed quickly before recombination of positive and negative ions occurs. However, the particles of the droplets are substantially separated by centrifugal force while swirling while receiving a strong centrifugal force action, but the droplets are further separated through a cyclone separator, and air containing negative ions added with water molecules is saunad. Air is blown into the room.

  The positive ions left in the droplets can be taken out as necessary, but when not needed, they are returned to the liquid tank and neutralized by grounding.

  When an atmosphere containing water molecule-added negative ions obtained by the above treatment and air containing mist generated from an ultrasonic humidifier was used to form an atmosphere having a humidity of 80% or more at room temperature, the ultrasonic humidifier The atmosphere formed by the air using the air produces a damp feeling, but in the atmosphere formed by the air using the negative ion generator, there is a dry feeling, and there is a marked difference in the feeling of both. all right.

  The reason for this difference in feeling is that the water droplets generated from the ultrasonic humidifier are generated from a negative ion generator, whereas the average particle size is 5-10 μm as a relatively large water droplet. The water droplets have an average particle size of 0.5 μm or less and a large amount of water droplets of 0.1 μm or less, which are presumed to be ultrafine water droplets or molecular groups.

  On the other hand, almost no negative ions were detected in the atmosphere of a high-temperature, low-humidity general dry sauna, and more than 1,000 positive ions / cc were detected on average. In normal air, both positive and negative ions are about 100 / cc. In the present invention, a large amount of negative ions was generated from the negative ion generator, and 10,000 to 100,000 negative ions / cc were detected in the sauna room. Although it is desirable that the number of negative ions is large, it has been confirmed that the desired effect can be obtained by maintaining an air atmosphere containing at least 1,000 negative ions / cc or more. An atmosphere of air containing 1,000 ions / cc or more of negative ions cannot be maintained unless artificially generating negative ions.

  By filling negative ions into the atmosphere in the sauna room, human blood vessels are dilated and sweating becomes easy, and it is not always necessary to keep the sauna room at a high temperature of 100 ° C. or higher. Therefore, contrary to the conventional sauna, a low temperature and high humidity sauna can be realized.

  Sauna is said to be less harmful to people with high blood pressure or heart disease than a steam bath, but if it is filled with negative ions, the heart becomes easier to work and the pulse is reduced. Because of the tendency, the risk decreases, breathing becomes easier and does not make you feel stuffy.

  Embodiments of the present invention will be described below with reference to the drawings.

Example 1
In FIG. 2, the present invention has a negative ion generator attached outside the sauna room 8. A sauna stove 1 is installed in the sauna room 8. The negative ion generator is roughly divided into a combination of a centrifugal force / Coriolis force generator 2 and a gas-liquid separator 4.

  The centrifugal force / Coriolis force generator 2 has an intake port 5, a liquid suction port 6, and an exhaust port 7. A high-speed airflow generator 3 is connected to the intake port 5 and external air is blown into the exhaust port 7. The air from which the separation device 4 is connected and the liquid is separated is fed from the output port. A tank 9 is connected to the liquid suction port 6 via a pump 10, and the liquid in the tank 9 is supplied. In the embodiment, the circulation line is formed by opening the output line of the gas-liquid separator 4 and the input line of the high-speed airflow generator 3 into the sauna chamber 8. In the embodiment, the negative ion generator is installed outside the sauna room and is connected to the sauna room 8 through the pipes 11 and 12. Alternatively, the ion generator is installed in the sauna room 8 and gas-liquid. The air supply port of the separation device 4 and the air intake port of the high-speed air flow generation device 3 can be used as an indoor installation type by opening the sauna chamber 8.

  The centrifugal force / Coriolis force generating device 2 is a mechanism that performs ion dissociation processing, droplet activation processing, and gas molecule ionization processing. In the embodiment, a spiral-shaped aerodynamic transport tube 13 has a spiral shape. A guide 14 is disposed along the axis, a nozzle pipe 15 is provided on the axis, and a water tank 16 is provided on the lower peripheral surface.

  Water in the tank 9 is pumped into the water tank 16 by the pump 10, and water in the water tank 16 is pumped up by the pump 17 and sent to the nozzle pipe 15. The tank 9 is equipped with a heater 19 and warms the supplied water to a necessary temperature.

  The guide 14 guides the air current in the aerodynamic transport pipe 13 and turns it in a spiral shape. The nozzle pipe 15 is located at the axial center of the aerodynamic transport pipe 13, and the gas is swirling around the nozzle pipe 15. Therefore, the guide 14 is not always necessary, but in the embodiment, the guide 14 is used. Therefore, the direction of the swirl direction of the airflow is regulated so that the Coriolis force faces the direction of the angular velocity vector of the earth's rotation. However, if the gas supply direction from the high-speed airflow generator 3 is set tangential to the inner periphery of the aerodynamic transport pipe 13, the airflow direction is automatically set to the clockwise and counterclockwise rotation flow. Is done.

  A nozzle 18 is opened at a peripheral surface along the axial center of the nozzle pipe 15, and the nozzle 18 ejects the liquid supplied from the water tank 16 into the aerodynamic transport pipe 13. In the embodiment, the nozzle 18 is an ion dissociation mechanism. Water is ejected from the nozzle 18 at a high pressure, and is ionized by obtaining energy. However, if water that has been subjected to ion dissociation in advance is supplied into the aerodynamic transport tube 13, ion dissociation is further promoted.

  The high-speed airflow generation device 3 is a fan for blowing air. In the embodiment, the air in the sauna room 8 is sucked and blown into the aerodynamic transport pipe 13 through the intake port 5.

  In the embodiment, the gas-liquid separator 4 uses a cyclone separator. The cyclone separator is effective for the separation of centrifugal force of gas and liquid as long as a certain speed or higher wind speed and pressure can be obtained in the air flow including fine water droplets discharged from the exhaust port 7 of the aerodynamic transport pipe 13. The gas-liquid separated air is introduced into the sauna room 8 through the conduit 11.

  In the embodiment, the high-speed air flow generator 3 is activated, the water in the water tank 16 is pumped up by the pump 17, and is ejected from each nozzle 18 of the nozzle pipe 15 into the swirling flow of the strong air current generated in the aerodynamic transport pipe 13. Let

  The water jetted into the aerodynamic transport pipe 13 receives a gas pressure, breaks up into the swirling air current, is dissociated into ions, and becomes fine water droplets along the guide 14 and is aerodynamically transported in the pipe while swirling. During this time, the water droplets flow in the axial direction while facing the tube wall due to the centrifugal force generated by the swirling flow of the air current and the Coriolis force, and the interface of the water droplets in contact with the gas is activated, and a dipole is activated on the surface of the water droplets When is oriented, oxygen molecules present at the gas side interface are ionized.

  The air stream containing air ions flows into the gas-liquid separator 4 from the exhaust port 7 of the aerodynamic transport pipe 13, water droplets remaining in the gas are removed, and the gas containing air ions is subjected to laminar flow treatment, The supply air is introduced into the sauna room 8 from the pipe line 11, and the air in the sauna room 8 is sucked into the pipe line 12 by receiving the suction force of the high-speed airflow generator 3, and newly introduced outside air is supplied if necessary. Then, it is again pumped to the centrifugal force / Coriolis force generator 2.

  On the other hand, water droplets adhering to the tube wall of the aerodynamic transport tube 13 and water droplets separated by the gas-liquid separator are returned to the water tank 16. Since this water droplet contains a lot of positive ions, the tube wall is grounded and neutralized.

  As mentioned above, although the horizontal type centrifugal force / Coriolis force generator is shown in the embodiment, the arrangement direction is not limited at all. Further, the negative ion generator may be installed in the sauna room by directly opening the intake port of the fan 3 and the air supply port of the bubble separation device 4 into the sauna room.

  5) Bathing time and temperature of experience bathers Three experience bathers (Mr. A, Mr. B, and Mr. C) who experienced bathing in the sauna of the present invention, dry sauna and mist sauna are appropriate at the temperature of each sauna. Table 4 shows the determined bathing time and the temperature.

Experience report in the sauna room according to the present invention (Mr. C)
Sensation when entering: Hot air (shock) when entering the room is softer than a general sauna (100 ° C). Breathing was easy. Also, when I entered the mist sauna, I felt uncomfortable due to a very moist feeling. This is considered to be due to the influence of large particles of 3 μm or more in a visible water droplet state. However, the water droplets generated from the negative ion generator have an average particle size of 0.5 μm or less and a large amount of water droplets of 0.1 μm or less, which are invisible ultrafine water droplets or molecules. Presumed to be a group.

  After entering the room, sweating started in 1 to 2 minutes, and after that, equilibrium sweating occurred, and sweating became intense in 3 to 4 minutes, but the nostrils and the interior did not get hot during breathing. (註 In ordinary saunas, the water inside the nostrils evaporates and becomes hot air. It is especially dangerous if wet towels are passed through.)

  The pulse was earlier than around 12-15 minutes. The moisture absorption of the paper in the sauna room was small (the equilibrium water content was unknown) and it was possible to read newspapers. The wetness was similar to that of a dry sauna. The pulse at the time of leaving was about 100 times / minute (normally 65 to 75 / minute).

  Table 5 shows the environmental differences and experience comparison between the sauna of the present invention and the dry sauna.

  According to the present invention, when the temperature in the sauna room is lowered to 30 ° C. at 98% humidity, the sweating start time is extended to 4 minutes, and when the temperature is adjusted to 50 ° C. and high humidity and 70% humidity, the sweating time is also increased. Was found to grow to 4 minutes. In addition, the negative ion in a sauna room reduces, so that it becomes high temperature.

  The reason why sweating becomes easy under low temperature and high humidity is thought to be because the water molecule-added negative ion molecule group directly acts on the skin and the like to open the sweat glands. Therefore, even a person with few sweating phenomena, which is common in women, can easily sweat according to the sauna of the present invention.

  It can be applied to so-called sauna baths used for physical therapy.
