Description

  TECHNICAL FIELD The present invention relates to a method and apparatus for generating negative ion-containing water droplets that are refined to an extent that does not cause an increase in humidity using activated water, and that supplies water to living space. is there.

  The phenomenon in which negative ions are generated in the air when water droplets break up in the air near a waterfall or fountain is well known as the Leonard effect. And the air containing negative ions generated in this way has a physiologically favorable effect such as mental stability, respiratory function enhancement, metabolism promotion, etc., and it is said that it helps human health. Many methods and apparatuses for artificially generating the negative ions have been proposed so far.

  For example, a method of generating a water curtain by mist by causing water to collide and scatter on a rotating body having a mesh, and generating negative ions through the air, and an apparatus used therefor (see Patent Document 1), In the water splitting part formed in the square tube for splitting into water droplets and generating negative ions in the air, the square tube has a polygonal cross section that forms an air flow path and is fed from the outside The negative ion generator which circulates in the shape of a turbulent flow while swirling in a square tube, and injects water into the air through a nozzle during this time, and finely splits this water (see Patent Document 2) , An ion generator that collides and charges fine water having a particle size of 650 nm or less with air ions (see Patent Document 3), and has a function of generating OH ions by lightly electrolyzing the surrounding water. A negative ion generator comprising an ion generation filter, humidified air generating means, and air blowing means for passing humidified air that has been pressurized or heated to the outside air through the ion generation filter (see Patent Document 4), cylinder Negative ion generator (see Patent Document 5), which includes a cylindrical body, a liquid jet rotator provided inside thereof, and a projecting wall provided along the inner wall of the cylindrical body with respect to the tangential direction thereof The body is placed so that the upper part is surrounded by a sirocco fan and the lower part protrudes from the fan casing and is immersed in water stored in the lower part of the housing. The sirocco fan is pumped and pulverized, and the generated water droplets are reprojected and pulverized onto the fan casing by the sirocco fan to increase the amount of negative ions generated. Generator (see Patent Document 6), in a processing chamber in which outside air can be introduced, the lower part of a rotating body whose diameter increases upward is immersed in water and rotated, thereby rotating along the outer periphery of the rotating body. A thin film of water is sequentially formed and scattered upward, and the scattered water collides with a screen having a mesh that allows water and air disposed around the rotating body to pass through. In a negative ion generator (see Patent Document 7) that increases the frequency of water collision using an inner wall, and an air ion generation method that atomizes water and supplies ionized mist into the air, the mist collides against the collision wall. When generating a flow of ionized mist, a method of generating air ions in which a permanent electric dipole crystal mineral is present on at least the surface of the collision wall or the ionized mist flow path to increase the number of ions (see Patent Document 8). Have been proposed.

  However, since these negative ion generation methods and devices all use tap water or sterilized tap water as the supply raw water, there is a limit to the activity improvement of the generated negative ions, and the mist containing sufficiently strong negative ions. If the size is increased in order to obtain the above, the humidity of the surrounding environment is unavoidably increased.

  Under the circumstances, the present invention has an object to provide a method and apparatus for generating a negative ion-containing mist that contains negative ions having higher activity and does not cause an increase in the humidity of the surrounding environment. It was made as.

  The present inventors have conducted various studies on a method for producing a mist that contains highly active negative ions and does not cause an increase in humidity when released into the surrounding environment. Used as water, formed into a spray form and collided with a perforated rotating body, further refined using centrifugal force, and contacted with ceramics containing tourmaline and magnetite to enhance the activity, Subsequently, it was found that the purpose can be achieved by separating the mist having a relatively large size and releasing only the fine mist to the surrounding environment, and the present invention has been made based on this finding.

  That is, the present invention atomizes supply water that has been activated in advance, contacts it with a rotating body with pores, disperses it by centrifugal force, and collides it with a ceramic plate for water activation arranged around the rotating body. After that, except for relatively large mist, only the fine mist is released to the surrounding environment, and a method for generating negative ions, and a plurality of ceramic plates for water activation are arranged on the inner wall. A cylindrical container formed in the containing mist discharge port, a rotating body with pores accommodated in the inside thereof, and a relatively large size mist that is disposed below the rotating body and separated by the action of the rotating body is collected. For receiving water or ceramic particles for water activation, optionally filled in the tray, and separating and activating relatively large size mist as agglomerated liquid Because of the water tank is disposed above the cylindrical container, and provides a negative ion generating apparatus characterized in that it is composed of water spray nozzles are connected by a water supply pipe through the water tank and the supply pump. In order to increase the activity of the circulating water, it is also possible to fill the water-receiving ceramic particles in the saucer.

The method and apparatus of the present invention will now be described with reference to the accompanying drawings.
FIG. 1 is a cross-sectional view showing an example of the structure of the apparatus of the present invention. Water stored in a water tank 2 installed inside a housing 1 is pressurized after passing through a filter 3 for removing fine particles in the water. The water supply pump 4 passes the water supply pipe 9 to the watering nozzle 10 and sprays downward in a conical shape. As the watering nozzle 10, a full-cone nozzle is used as the watering nozzle 10 that is less likely to be clogged. The cylindrical rotating body 7 with pores for receiving the sprayed water is rotated at high speed by the motor 5 and the driving belt 6. The minute water droplets sprayed downward by the watering nozzle 10 come into contact with the cylindrical rotating body 7 with pores and two to three wire meshes 8 attached thereto, and are scattered around at high speed by centrifugal force.

  The minute water droplets scattered around collide with a large number of water activation ceramic plates 14 arranged inside the cylindrical container 12 and are scattered to become mist. Although the mist floats in the air, a part of the mist having a relatively large size is further crushed by the blades 17 attached to the rotating body 7 with pores and scattered upward. The ceramic plate 14 for water activation contains magnetite and tourmaline.

  Air containing mist filling the inside of the cylindrical container 12 that generates negative ions is sent upward by the blower fan 18 and the blades 17, but is intercepted by the inner wall 11 on the way, so it falls along the inner wall. The ultrafine mist is sent to the discharge port 13 through the gap between the inner wall 11 and the cylindrical container 12. By the action of the inner wall 11, it is possible to prevent a relatively large size mist that causes an increase in humidity from being sent to the discharge port 13.

  The large mist that has fallen without being sent to the discharge port 13 is collected in the water tank 2 after passing through the ceramic particle 15 containing magnetite grains and tourmaline stored in the receiving tray 16 with pores or in some cases, and pressurized. It is sent to the watering nozzle 10 again by the water absorption pump 4. The magnetite and tourmaline in the saucer 16 and the water activated by the tourmaline and magnetite contained in the ceramic plate 14 for water activation are repeatedly circulated inside the housing 1, and the ultrafine mist by the activated water is discharged from the outlet. 13 is sent to the room.

When the apparatus of the present invention is placed indoors, the air containing negative ions is blown directly into the room through the indoor blowing L-shaped member 20 attached to the discharge port 13. When this apparatus is placed outdoors, the air is blown into one or a plurality of desired rooms through the bellows type blower hose 21 shown in FIG. 2 and the current divider 22 installed on the back of the ceiling. Since the blower hose 21 is easy to attach and detach, cleaning and replacement can be easily performed.
The water tank 2 is provided with a drain valve 23 and can be electromagnetically opened and closed by a switch operation of the controller 19.

  Thus, in the method of the present invention, a multi-stage mist generation mechanism is employed to increase the negative ion generation density. That is, the first stage is a watering nozzle that sprays pressurized water, and the nozzle sprays pressurized water in a conical shape. The second stage is a rotating body with fine pores that scatters water droplets by centrifugal force and a metal wire for scattering. The relatively large water droplets that have fallen into both form finer water droplets that collide with the inner wall at high speed by centrifugal force. Let In the third stage, the collided water is scattered again by a large number of water activation ceramic plates installed on the inner wall, and the ratio of fine mist is further increased. In the fourth stage, water droplets of relatively large size that have fallen through these mechanisms are crushed by blades attached to the cylindrical rotor with pores.

  In the negative ion generator using the Leonard effect, a large amount of fine water droplets are generated by crushing water, but if this is discharged into the room as it is, a rapid increase in humidity is inevitable. It is known that the increase in humidity is mainly caused by a relatively large size mist, and the ultrafine mist of a smaller size is known not to make a significant contribution to the increase in humidity. The ratio of ultrafine mist is increased by crushing water step by step, and furthermore, the relatively large size mist that causes the humidity increase is removed by the double wall, so the increase in humidity is suppressed. Is done.

In order to enhance the physiological activity of the crushed fine water droplets, the water scattered by centrifugal force is crushed by a ceramic plate containing tourmaline and magnetite. Tourmaline is known to contribute to the generation of negative ions by the piezoelectric effect, and the generation of negative ions is promoted by the action of water droplets that collide at high speed. Magnetite is known to activate water by magnetic action and to have a high physiological effect as a water treatment agent. In addition, since the water that has aggregated and dropped contacts the ceramic particles containing magnetite ore and tourmaline, and repeatedly circulates in the apparatus, activation of the water is promoted by a synergistic effect with crushing by the ceramic plate. .
In the method of the present invention, the released fine mist has a particle size of 50 nm or less, preferably 20 nm or less.

  3 is a perspective view of the apparatus shown in FIG. When replacing the water in the aquarium 2, the drain valve 23 is opened to drop the water into the drainage container 24, the side door 27 attached to the housing 1 is opened, the drainage container 24 is taken out and the water is drained. Throw away and open the water supply cap 25 of the water tank 2 to supply water. The opening 26 of the water supply cap 25 is wide open so that the water tank 2 can be easily cleaned.

  FIG. 4 is a side sectional view of a cylindrical portion showing a different example of a cylindrical rotating body with pores, FIG. 5 is an upper plan view, and FIG. 6 is a perspective view. In these drawings, the blades 28 are attached to the central axis 29 of the cylindrical rotor with pores, and the structure is different from the blades 17 attached to the outside of the cylindrical rotor 7 with pores. Which type of blade is used is determined by a combination of the pressure of the pressure pump, the type of watering nozzle, the number of wire meshes, and the like.

  According to the method and apparatus of the present invention, negative ions can be generated with higher efficiency than in the conventional method and apparatus, and the humidity of the surrounding environment is not increased by the released mist.

  Next, the best mode for carrying out the present invention will be described by way of examples. However, the present invention is not limited thereto.

In the apparatus shown in FIG. 1, when operated under conditions of a water storage amount of 10 liters, a spray nozzle spraying capacity of 4 liters / minute, and a rotating body with pores (diameter 145 mm, length 110 mm, rotation speed 3000 rpm), minus A maximum of 600,000 to 700,000 ions / cc was obtained near the discharge port. In an experiment in which the apparatus was placed outside and air was blown for 20 minutes from the corner of the ceiling of an 11 tatami room, the average value of negative ions in the center of the room was 3200 / cc. In an experiment in which air was blown for 30 minutes in a 14 tatami room, numerical values of 3500 pieces / cc to 3900 pieces / cc were obtained at the corners of the room. Considering that the number of negative ions in the vicinity of the waterfall is about 1000 to 2500 / cc, the negative ion generator of the present invention has the ability to supply a sufficient amount of negative ions to a large room. I understand.
Note that the amount of negative ions generated in the conventional negative ion generator is on the order of tens of thousands to several tens of thousands.

  When the device according to the present invention was operated under the same conditions as in Example 1, the humidity increase after 1 hour in a 14 tatami room was 2-3%. On the other hand, when the conventional apparatus was used, a humidity increase of 8 to 10% was recognized.

  Table 1 shows the results of an experiment comparing the influence of released air on the human body using wave activity when operated using the apparatus of the present invention under the same conditions as in Example 1. The wave activity is obtained by classifying and displaying the heights of various codes relating to physiological functions of the human body into numerical values of 1 to 20, and the higher the numerical value, the better the function. Here, the measurement results for the immune code used as the most general code are shown.

  In both cases of the two test subjects, the wave activity value was higher when the water activation materials 14 and 15 were present, and the effectiveness of the water activation material was confirmed. Even when there is no material for water activation, the value of wave activity is significantly higher after use than before use, and the physiological effect of negative ions of this device due to the multistage fine water droplet generation mechanism. This is a proven result.

  It is useful for health promotion by Leonard effect.
