Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a negative ion generator that generates negative ions in the air using the Leonard effect (waterfall effect).
[0002]
[Prior art]
When a water droplet breaks up in the air, more precisely, when a water droplet collides with a metal plate, which is a barrier, and splits, negative ions are generated in the nearby air, and the water droplets are equal in amount to positive ions. The phenomenon of obtaining an electric charge has long been known as the Leonard effect (Lenard's effect). This phenomenon is also called the waterfall effect because negative electricity exists in the air near the waterfall.
[0003]
A method of generating negative ions using the Leonard effect is described in, for example, Japanese Patent Publication No. 5-587555. In this method, fine water droplets are generated from water by a fine water droplet making machine, and at the same time, air is blown into the fine water droplets at a wind speed of 0.5 to 50 m / sec to form fine water droplet mixed air, and then the fine water droplet mixing is performed. By passing air through a separator, fine water droplets having a particle size of at least 1 μm are separated to form ultrafine water droplet mixed air, and negative ions are generated in 1.25 × 10 ⁹ or more in 1 m ^{3 of the} ultrafine water droplet mixed air. Is. In this preceding example, the fine water droplet making machine is a water splitting unit, and the separator is a gas-liquid separating unit. In the water splitting section, a device that ejects water at high pressure and collides with the impingement wall, a device that injects water onto a rotating disc and applies centrifugal force to the sprayed water to split it into fine water droplets, ultrasonic humidification A device that vibrates water and divides it into fine water droplets or a device that blows water onto a rotating impeller and smashes the water with an impeller to divide the water into fine water droplets is used. A separator is used.
[0004]
When using the above apparatus, fine water droplets generated in the water splitting section are blown, and the fine water droplets are separated from the air in a cyclone separator, which is a gas-liquid separation section, to extract air containing negative ions to the outside. it can.
[0005]
[Problems to be solved by the invention]
By the way, the negative ion generator is equipped with a water tank, the water in the water tank is pumped up and supplied to the water splitting part, and most of the water supplied to the water splitting part and the gas-liquid separation part are separated. A system is used in which the collected water is collected in a water tank and circulated.
[0006]
In the water splitting unit, water is split into fine water droplets in the air taken from outside air, so dust collected in the air is taken in and contaminated in the water collected in the water tank. Need to change the water. Of course, it must be considered that not only dust in the air but also other bacteria such as bacteria, viruses and molds floating in the air are taken in. When germs are taken up into the water, there is a risk of rapid propagation in the aquarium if the temperature conditions of the water are compatible with the survival of the germs.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
[0012]
1 to 3, the negative ion generator includes a water splitting unit 2, a gas-liquid separation unit 3, and a water tank 4 in a case 1.
[0013]
The water splitting unit 2 is a part that splits the water supplied from the water tank 4 into fine water droplets and blows air containing the fine water droplets to the gas-liquid separating unit 3. It is a part that separates and removes water droplets in the received air and sends out humid air containing negative ions to the outside, and the water tank 4 is filled with water to be supplied to the water splitting unit 2. In the figure, 5 is an air intake opening opened at the bottom of the case 1, and 6 is an air supply opening opened at the upper surface of the case 1. An air flow path 7 is provided between the air intake 5 and the air supply port 6. The air flow path 7 has a blower 8, and the water splitting unit 2 and the gas-liquid separation unit 3 are located downstream of the blower 8. Each is formed in the air flow passage 7.
[0014]
The water splitting unit 2 includes a nozzle 9 and a barrier 10, and a water supply pipe 11 that communicates with the nozzle 9 is connected to the water tank 4 through a pump 12. A plurality of nozzles 9 are attached in parallel to a portion of the pipe 11 a arranged in a horizontal posture with the jet port facing downward, and the barrier 10 is arranged below the nozzle 9 so as to face the jet port of the nozzle 9. It is installed.
[0015]
In the present embodiment, a block having an isosceles triangular cross section is used as the barrier wall 10, and two inclined surfaces forming a right angle are used as the collision surface 13. In addition, a large number of vertical grooves 14 are attached to the collision surface 13 in parallel.
[0016]
The use of the two sides of the isosceles triangular block as the collision surface 13 is based on a negative ion generation amount measurement experiment, and is not necessarily limited to this example. According to the experiment, the amount of negative ions generated is larger when the spray water of the nozzle 9 is collided with the inclined surface than with the surface orthogonal to the ejection direction. It is preferred that Further, even when the jet water collides with the orthogonal surface, when a plurality of appropriate holes are made in the flat plate surface, negative ions equal to or higher than those are generated. According to experiments, a large amount of negative ions is generated when the jet water collides with the convex portion and breaks up into fine water droplets. It is desirable that no water film be formed on the impinging surface of the jet water. The recess receives the jet water and forms a water film. Even if jet water collides with the water film, the amount of negative ions generated is small. The humid air containing negative ions descends the air flow passage 7 of the water splitting section 2, then turns up and turns up the air flow path 7, and is introduced into the gas-liquid separation section 3. Two or more baffle plates 15 are arranged in a zigzag manner along the air flow passage 7 in the air flow passage 7 of the gas-liquid separator 3. The air received in the gas-liquid separation unit 3 collides with the baffle plate 15 while rising in the air flow passage 7 of the gas-liquid separation unit 3, and the baffle plate 15 captures minute water droplets contained in the air. And remove from the air.
[0017]
Therefore, fine water droplets in the air are removed while the air passes through the gas-liquid separation unit 3, and humid air containing negative ions is taken out from the air supply port 6. Note that most of the water sprayed to the water splitting unit 2 and the water separated from the air by the gas-liquid separation unit 3 fall into the water tank 4 in the case 1 and are circulated for use.
[0018]
In the present invention, various germs including bacteria and viruses in the water to be supplied to the water splitting section 2 are removed. A germicidal lamp is used to remove germs. Bacteria lamp is a discharge lamp using a glass tube to improve transmits ultraviolet light, emit strongly ultraviolet strong 2537 Å germicidal exiting from mercury. In FIG. 3, the germicidal lamp unit 19 is assembled to a part of the water supply pipe 11 connecting the water tank 4 and the nozzle. The sterilizing lamp unit 19 has a vertically long underwater sterilizing lamp 23 inserted in a pipe 22 having a water supply port 20 and a water supply port 21. The sterilizing lamp 23 is turned on, and water flowing in from the water supply port 20 is sterilized. 23, ultraviolet rays are irradiated while flowing in the gap between the pipes 22 to remove germs in the water, and sterilized water is supplied from the water supply port 21 to the nozzle pipe 11 a and sprayed from the nozzle 9. The water sprayed from the nozzle 9 breaks up into fine water droplets and generates negative ions in the air. Most of the water is collected in the water tank 4, and the water is irradiated with ultraviolet rays while being repeatedly circulated between the water tank 4 and the nozzle 9. The propagation of germs taken into the water in response to this is suppressed.
[0019]
In the embodiment, a see-through window 16 is provided in a part of the case 1 so that the water splitting portion 2 can be seen from the outside through the see-through window 16, and at least at the installation position of the barrier wall 10 of the water splitting portion 2. Correspondingly, a transparent window 16 is provided in a part of the front panel 17. The see-through window 16 is obtained by fitting a transparent plate such as transparent glass or transparent plastic into the opening of the panel 17. In order to express the image of the waterfall, it is preferable to form the see-through window 16 in a vertically long shape so that the barrier 10 and a part of the space below it can be seen through.
[0020]
In addition, a lighting tool 18 is installed in the case 1 to illuminate the state of water splitting into fine water droplets when the water jetted from the nozzle 9 collides with the barrier 10. The illumination tool 18 may be an LED, a fluorescent lamp, an incandescent lamp, EL, plasma emission, or the like. As an illumination method, in addition to direct illumination by the illumination tool 18, illumination is performed indirectly using an optical fiber or a prism. be able to. Since the water splitting part 2 in the case 1 is a humid environment in which water sprayed from the nozzle 9 is scattered, it is necessary to perform a waterproof process on the lighting fixture 18 in the case of direct lighting. When performing indirect illumination using an optical fiber, the illuminator 18 can be placed outside the air flow path 7 and the light emitting end of the optical fiber can be exposed in the flow path of the humid environment. A germicidal lamp can also be used for the lighting device.

【The invention's effect】
As described above, according to the present invention , a large number of negative ions are generated by using the inclined surfaces on the two sides of the isosceles triangular block arranged below the nozzle as the collision surface and causing the jet water of the nozzle to collide with the inclined surface. In order to remove germs by installing a germicidal lamp in the water supply line to the water splitting section, fine water droplets generated in the water splitting section can be kept sterile, Even if the water ejected from the nozzle of the part touches the air and takes in germs in the air, it is sterilized until it is collected in the water tank and then ejected from the nozzle, and the circulation between the water tank and the nozzle is repeated. There is an effect that clean negative ions can be generated without propagation of germs in the water tank and thus without releasing the germs.
