Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention discharges air containing negative ions into a room to enhance the metabolism of the human body,
The present invention relates to a negative ion generator that provides a health effect such as soothing a nerve.

[0002]

2. Description of the Related Art In recent years, hydroxyl ions (H ₃₎ formed by binding of hydroxyl ions (OH ⁻ ) to surrounding water molecules are formed.
O ₂ ^-) negative ions, such as the incorporation into the body,
Attention has been paid to the hypothesis that body fluids are made weakly alkaline and metabolism is activated, and other beneficial effects are obtained, and there are other useful effects such as deodorizing effects. Has been proposed.

[0003] As a conventional negative ion generator,
Heat is applied to a metal plate such as a steel plate that generates negative ions and emits it into the air by colliding water vapor with a special plastic wall surface, or a steel plate that has stone powder adhered to the surface. There is known a device in which negative ions are generated by colliding pressurized air and released into the air.

[0004] On the other hand, as a device using tourmaline (tourmaline), water is passed through a tourmaline layer to generate ionized water, or tourmaline powder is attached to batting of futon to remove negative ions. It is known to generate the negative ions while sleeping at the same time.

[0005]

However, in the above-mentioned conventional negative ion generator, there is a problem that the efficiency of generating negative ions is low, and the apparatus is increased in size and cost is increased. In addition, since a normal temperature water tank is used in the open space and tap water and distilled water are additionally replenished, microorganisms and pathogenic bacteria will propagate in the water tank and adversely affect respiratory organs, and mold and ticks such as mite There were problems such as promoting breeding.

[0006] It should be noted that even the use of tourmaline produces ionized water and generates a slight amount of negative ions, so that a large amount of negative ions cannot be released into the air. .

The present invention has been made in view of the above-mentioned conventional problems, and has as its object to provide a simple and inexpensive negative ion generator capable of discharging air containing a large amount of negative ions into a room.

[0008]

SUMMARY OF THE INVENTION The negative ion generator of the present invention causes light electrolysis of ambient moisture to reduce OH
An ion generating filter that holds fine powder having a function of generating ions and has air permeability, humidified air generating means, and generates humidified air that has been subjected to one or both of pressurization and heating of outside air. The fine powder generates static electricity and discharges through the surrounding water to electrolyze the surrounding water to generate OH ions. By attaching water particles to the surface and applying heat or a pressure of about 100 Pa to give a temperature difference of 10 ° C. or more to the outside air, OH ions are generated and combined with surrounding water molecules, and a large amount of negative ions are generated. The ions can be continuously and efficiently generated, and the air containing the negative ions can be released into the room. In addition, since it is only necessary to blow pressurized or heated humidified air toward the ion generation filter, it is possible to provide a simple and inexpensive structure.

Fine powders having a function of generating OH ions are known as tourmaline (tourmaline), samarskiite, healgrinite, xenoite, modified zircon, troglodytes, etc. stone)
Has a particularly large effect.

[0010] The ion generating filter may be constructed by storing fine powder in a breathable storage body, or by converting fine powder into a paint and applying it to metal, wood, glass or the like. If the fiber or the fiber structure is attached by using a dyeing technique or the like, the air permeability is high and the surface area of the fine powder adhered is extremely large, so that negative ions can be generated with extremely high efficiency.

Since the electrostatic voltage generated by the fine powder is inversely proportional to the square of the length of the crystal, the smaller the powder is, the higher the generated electrostatic voltage is, which is 3 μm or less, preferably 0.1 μm or less.
A great effect is exhibited by setting the thickness to about 1 to 1 μm.

[0012] Further, the humidified air generating means is constituted by arranging a capillary member partially immersed in a water container containing an aqueous solution containing distilled water as a main component so as to face a ventilation passage toward an ion generating filter. With a simple configuration, moderately humidified air can be sent to the ion generation filter,
It can generate negative ions effectively, and since distilled water is used, lime does not adhere to the surface of furniture or metal products as in the case of using tap water.

[0013] Further, by adding an antibacterial agent such as ethyl alcohol and wood vinegar to distilled water as an aqueous solution, it is ensured that microorganisms and pathogenic bacteria propagate in the aqueous solution and diffuse into the air. It can be prevented, and also exhibits a mite repellent effect in the room.

Further, if the cartridge having the humidified air generating means and the ion generating filter is detachably mounted in the cylindrical housing having the fan motor disposed at the lower portion, the cartridge is replaced when the aqueous solution is exhausted. And maintenance is easy.

In addition, a dust filter is disposed below the cylindrical water container having the air passage formed in the shaft core so as to cross the air passage, and a part of the capillary member is immersed in the water container. It is arranged to extend to the upper part of the water container and cross the air passage, and to arrange the ion generating filter to cover the air passage at the upper part of the water container. It is possible to provide a cartridge capable of stably obtaining a required action.
