Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a negative ion generator for generating negative ions in the air using the Leonard effect (waterfall effect).

[0002]

2. Description of the Related Art When a water droplet splits in the air, more precisely, when the water droplet collides with a metal plate serving as a collision wall and splits, negative ions are generated in the air nearby, and the water droplets become negative ions. The phenomenon of obtaining the same amount of positive charge as the Leonard effect (Lenard effect)
d's effect).
This phenomenon is called the waterfall effect because negative electricity exists in the air near the waterfall.

A method of generating negative ions by utilizing 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 manufacturing machine, and the fine water
Air is blown at ５０50 m / sec to form fine water droplet mixed air, and then the fine water droplet mixed air is passed through a separator to separate fine water droplets having a particle size of at least 1 μm to form ultrafine water droplet mixed air. Super fine water drop mixed air 1m
^{In step 3} , negative ions are generated in an amount of 1.25 × 10 ⁹ or more. In this prior example, the fine water drop making machine is a water splitting section, and the separator is a gas-liquid separating section. In the water splitting unit, a device that jets water at high pressure and collides with the impingement wall, a device that jets water onto a rotating disk, applies centrifugal force to the jet water to split it into fine water droplets, and ultrasonic humidification A device that vibrates water to break it into fine water droplets or a device that sprays water onto a rotating impeller and hits the water with the impeller to break it into fine water droplets is used. A separator is used.

In the above-described apparatus, fine water droplets generated in a water splitting section are blown, and the fine water droplets are separated from air in a cyclone separator, which is a gas-liquid separating section, to remove air containing negative ions to the outside. Can be taken out.

[0005]

By the way, in order to split water into fine water droplets, energy must be given to the water. There is a problem that when energy is given to water, a sound is emitted, which causes noise. For example, a method in which water is jetted at high pressure and the jet water collides with an impingement wall is an effective method for generating air ions by faithfully reproducing Leonard's experiment, but impinging on the inner wall of the air pipeline. It is known that a loud impact sound is generated when water is applied to the inner wall of the air duct when used on a wall. Such impulsive sounds have conventionally been considered to be noise.

However, the clarity of the air and the sound are not unrelated. A pleasant clarity can be obtained near the waterfall or at the seashore, but the sound of the waterfall is roaring, and the beach has a peculiar sound. Neither would be called noise. As for the Leonard effect, a large amount of negative ions are generated in the air near the waterfall, which is also called the waterfall effect, and these negative ions give the person a sense of clarity.

An object of the present invention is to provide a Leonard effect (waterfall effect).
To provide a negative ion generator capable of realizing the above.

To achieve the above object, a negative ion generator according to the present invention is a negative ion generator having a water splitting section and a see-through window, wherein the water splitting section is supplied. The water is split into fine water droplets in the case to generate negative ions in the air, and the see-through window allows the state of water droplet splitting occurring in the water splitting part to be seen through from the outside of the case.

The water splitting section has a nozzle and a collision wall,
The nozzle jets the supplied water, the collision wall is a surface that collides and scatters the water jetted from the nozzle, and the see-through window collides with the collision wall and shows a state of water falling. This is to be seen through.

[0010] Further, a plurality of nozzles are provided in a pipe of a nozzle arranged in a horizontal posture, and each nozzle has a jet port for jetting water downward, and a collision wall is provided below the nozzle pipe. It is provided and has an inclined surface, the inclined surface is a collision surface with which the jet water from the nozzle collides, and the see-through window allows at least the inclined surface of the impingement wall to be seen through from the outside.

In addition, the lighting device has a lighting device, and the lighting device irradiates a light beam to the water splitting portion to emit light of water split into fine water droplets.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings.

In FIGS. 1 to 3, the negative ion generator comprises:
The case 1 includes a water splitting section 2, a gas-liquid separation section 3, and a water tank 4.

The water splitting section 2 splits the water supplied from the water tank 4 into fine water droplets, and blows air containing the fine water drops to the gas-liquid separating section 3. Part 2
The water tank 4 is a part that separates and removes water droplets in the received air and sends out humid air containing negative ions to the outside.
The water to be supplied to the water splitting section 2 has been charged. 5 in the figure
Is an air intake opening at the bottom of the case 1;
Is an air supply port opened on the upper surface of the case 1. An air flow passage 7 is provided between the air inlet 5 and the air inlet 6, and the air flow passage 7 has a blower 8. The water splitting unit 2 and the gas-liquid separation unit 3 are located downstream of the blower 8. These are formed in the air flow passage 7 respectively.

The water splitting section 2 has a nozzle 9 and a collision wall 10, and a nozzle pipe 11 is connected to the inside of the water tank 4 via a pump 12. A plurality of nozzles 9 are attached in parallel to a portion of the pipe 11 arranged in a horizontal posture with the ejection port facing downward, and the impingement wall 10 is disposed below the nozzle 9 facing the ejection port of the nozzle 9. Has been established.

In the present embodiment, a block having an isosceles triangular cross section is used as the collision 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 provided in parallel on the collision surface 13 as shown in FIG.

The use of the two slopes of the isosceles triangular block as the collision surface 13 is based solely on an experiment for measuring the negative ion generation charge, and is not necessarily limited to this example. According to the experiment, the amount of negative ions generated is larger when the jet water from the nozzle 9 collides with the inclined surface than when the jet water collides with the surface perpendicular to the jet direction. Preferably. Further, even when the jetted water collides with the orthogonal surface, if a plurality of appropriate holes are made in the flat plate surface, the same or more negative ions are generated. According to experiments, a large amount of negative ions are generated when the jetted water collides with the convex portion and breaks into fine water droplets. It is desirable that a water film is not formed on the collision surface. The concave portion receives the jet water and forms a water film. Even if the jet water collides with the water film, the amount of negative ions generated is small. The humid air containing negative ions descends through the flow path 7 of the water splitting section 2, then turns back up and rises, and is introduced into the gas-liquid separation section 3.
Two or more baffles 15 are zigzagly arranged along the flow path 7 in the flow path 7 of the gas-liquid separation unit 3. The air received in the gas-liquid separator 3 collides with the baffle plate 15 while ascending in the flow passage 7 of the gas-liquid separator 3, and the baffle plate 15 captures fine water droplets contained in the air. To remove from the air.

Therefore, fine water droplets in the air are removed while the air passes through the gas-liquid separation section 3, and the humid air containing negative ions is taken out of the air supply port 6. Most of the water injected into the water splitting unit 2 and the water separated from the air in the gas-liquid separating unit 3 fall into the water tank 4 in the case 1 and are circulated.

According to the present invention, a transparent window 16
The water splitting section 2 can be seen through the see-through window 16 from the outside. In FIG. 3, a see-through window 16 is provided on a part of the front panel 17 corresponding to at least the installation position of the collision wall 10 of the water splitting unit 2. See-through window 16
Is one in which a transparent plate such as transparent glass or transparent plastics is fitted 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 vertically long so that the hit wall 10 and a part of the space below the hit wall 10 can be seen through.

A lighting device 18 is provided in the case 1 to illuminate a state in which water jetted from the nozzle 9 collides with the impingement wall 10 and breaks into fine water droplets. Lighting equipment 1
LED, fluorescent lamp, incandescent lamp, EL, plasma light emission, etc. can be used for 8. As an illumination method, in addition to direct illumination by the illumination device 18, indirect illumination using an optical fiber or a prism can be used. it can. Since the water splitting portion 2 in the case 1 is a humid environment in which the water jetted from the nozzle 9 is scattered, the lighting device 18 needs to be waterproofed in the case of direct lighting. When performing indirect illumination using an optical fiber, the illuminating device 18 can be placed outside the air flow path 7 to expose the light emitting end of the optical fiber into the flow path in a humid environment. The figure shows an example in which the lighting device 18 is arranged above the nozzle 9.

In the present embodiment, the water jetted downward from the nozzle 9 collides with the collision wall 10, and the water colliding with the collision wall 10 falls as a waterfall. The sound emitted is the sound of a waterfall, and the appearance of the waterfall is illuminated by a lighting device 18 and appears in the see-through window 16. The image when water is sprayed upward from the nozzle 9 is a fountain, and when water is dropped or sprayed on a rotating disk, an image of a water wheel or a turbine can be represented. We will see the waterfall as splashes. Both are water scattering,
The state of the fall is illuminated by the lighting device 18, and the state of the waterfall can be visually confirmed.

[0022]

As described above, according to the present invention, the appearance of the waterfall can be visually confirmed by making it possible to see from outside the state in which the jet water collides with the impingement wall and is scattered. The sound emitted can be impressed by the sound of a waterfall. Therefore, the operating noise of the device, which has been considered as a noise, can be made to be felt as a clear sound by clarifying the cause thereof, and the effect of realizing the Leonard effect can be realized.
