Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ionization phenomenon known as the Leonard effect, in which water droplets are charged with cations and ambient air is charged with anions when water is broken and mist is generated. The present invention relates to an anion generator that is artificially generated. In particular, it was developed in order to provide an anion generator that is comparable in size to the conventional large-scale equipment by making the device compact and saving power. The air we breathe has 1000 to 2000 ions per cm ³ . The ratio of cations and anions is said to be 5: 4. However, in the city, the ion balance is 5
In some cases, the number of anions is close to zero, such as in pair 1. This is due to the unnatural environment of the city. Friction between steel, concrete, and transportation vehicles and air creates cations, and the metal body is charged with static electricity and attracts anions. Air conditioners and OA equipment at work tend to adsorb anions, resulting in increased cations. This invention is a health device that expects medical effects such as fatigue recovery due to an increase in the concentration of anions in the air, and bacteria, dust, odor, and impurities in the air introduced into the device by a fan It is intended to provide an anion generator which is excellent as an indoor environment improving device by being attached with mist and removed.

2. Description of the Related Art Anion generators include those that use corona discharge that directly applies energy to air itself or ionization by radioactive substances. Since this is direct ionization for air, it oxidizes ions, so ozone, nitrogen oxidation Fatal defects that many harmful substances such as substances and sulfur oxides are generated, and electrically generated anions have a lot of activity because they are not bound to water molecules and directly become cations. It was neutralized. Therefore, a conventional typical anion generator is disclosed in Japanese Patent Application Laid-Open No. 9-2
Japanese Patent Application No. 85555 (Japanese Patent Application No. 8-127675). As shown in FIG. 7, by immersing the lower part of the inverted conical rotor R in water and rotating it, the water was made to rise in a thin film shape along the outer periphery of the rotor R and finally scattered and scattered. The water collides with the cylindrical screen S having a mesh arranged around the rotating body to generate mist, and the sirocco fan F provided on the upper part of the rotating body R takes in the outside air and at the same time, the mist from the duct. It is designed to be discharged to the outside.

[0003]

In the anion generator in the conventional example, the water film rising along the outer periphery of the rotating body R has a structure of the rotating body R having an inverted conical shape. It was apt to scatter around, and the rate of not reaching the cylindrical screen S was very high, and the defect that the amount of mist generated was reduced was recognized. Further, the sirocco fan F, which is attached to the upper part of the rotating body R and serves both as an intake and an exhaust, also has a single motor M.
Although it becomes compact as a whole because it is rotated with,
The sirocco fan F acts as a resistance to reduce the amount of mist generated and impair the durability of the rotating body R. In addition, air is originally purified by anion generation plus a water filter method, but since the outside air is directly introduced and discharged, there is a limit to what can be purified and removed with the water curtain in the compact type, and the dirt in the outside air can be immediately cleaned. There is a tendency that the stains of (1) and (2) progress and hinder the generation of anions. Therefore, it may be necessary to replace the water in a short time, or the float switch may malfunction. If frequent cleaning is neglected, the dirt in the exhaust duct accumulates and the accumulated mist accumulates, which causes a decrease in the amount of discharged anions.

[0004]

According to a first aspect of the present invention, air is purified by introducing outside air through a filter into the inside by a blower and passing water through a water curtain sprayed from a nozzle to remove anions and fine mist. In the anion generator designed to be discharged, the mist generator is arranged so as to be immersed in a water tank below the pumping cylinder having a funnel shape and provided with a nozzle for scattering a plurality of water around the upper part. A cap-shaped crushing device that covers the water cylinder as a whole is configured to be connected to the output shaft of the motor, and a pumping blade consisting of multiple ridges is formed in the axial direction in the pumping cylinder to increase the amount of water. The crushing fork, which is vertically provided around the crushing means, is arranged so that the rod bodies facing the nozzle and having a square cross-section are arranged alternately and densely.

The gist of the invention of claim 2 is that the motor is arranged in the lower part of the water tank, and the output shaft of the motor is passed through the pumping cylinder and fixed to the disc of the crushing means. It is a thing. The gist of the invention of claim 3 is that, in a crushing fork vertically provided around the crushing means, a cylindrical rod for colliding and dispersing water droplets from the nozzle is provided at a position facing the nozzle, and the crushing has a square cross section. The feature is that the lengths of the forks are uneven. The gist of the invention of claim 4 is to face the crushing means of the mist generator, to arrange a cyclone cylinder, to blow ultrafine mist with anions and to return mist with a large particle size to the water tank. It is a feature.

BEST MODE FOR CARRYING OUT THE INVENTION The details of the anion generator according to the present invention will be described below based on the embodiments shown in FIGS. FIG. 1 is a perspective view of the whole anion generator according to the present invention.
1, a main body 1 provided with a control unit 12 such as a switch in the center and a window 13 for looking inside, an inner lid 2 provided with a cyclone cylinder 21, and an upper lid 3 provided with an outlet 31 on the upper surface. A water tank 14 provided with a solenoid valve 141 for drainage is provided in the upper portion of the main body 1, and a drainage tank 15 is disposed below the water tank 14.
Although not shown, the drain tank 15 can be taken out from the side surface. In this embodiment, the inner lid 2 and the upper lid 3 are removed and water is supplied from above, but a water supply tank is provided inside and water is automatically supplied when the water level in the water tank 14 drops. A configuration can also be adopted.
Float switches 142 and 143 for sensing an appropriate water level in the aquarium 14 and a water level at which it becomes necessary to replenish water, respectively.
Is provided so that it can be recognized by the lamp or buzzer of the control unit. When the automatic water supply device is incorporated, water supply and stoppage are performed in cooperation with the float switches 142 and 143. For the automatic water supply device, stop the device according to the operating time of the device, operate the solenoid valve 141 to automatically drain water (manual drainage is possible), and connect the water in the water tank 14 to the drainage tank 15 or a hose to the side surface. It can also be configured to drain to the outside and replace the water.

A mist generator 5 is provided in the water tank 14. The mist generator 5 comprises a pumping cylinder 51, a cap-shaped crushing means 52, and a motor 53. The output shaft 531 of the motor 53 is penetrated through the pumping cylinder 51 and the crushing means 52, and the nut 54 is screwed into the male screw formed at the end of the output shaft 531 to be integrated. The pumping cylinder 51 is arranged so as to immerse the lower part in the water tank 14, has a funnel shape, and is provided with four nozzles 511 that scatter water rising inside the pumping part 51 at the upper part. A water pumping blade 512 consisting of a plurality of protrusions is provided so as to guide a water film that rises inside due to centrifugal force due to rotation. The crushing means 52 has a cap shape and covers the pumping cylinder 51. A large number of crushing forks 522 ...
An annular recess 523 is formed by a small concentric projection into which the upper portion of the pumping cylinder 51 is fitted, and a hole 524 through which the 531 of the output shaft is inserted is formed in the center. A water film rising in the pumping cylinder 51 by centrifugal force due to the rotation of the motor 53 is radially ejected from the nozzle 511 and collides with the crushing fork 522 to become a mist. A portion of the crushing fork 522, which faces the nozzle 511 and is first hit by a water droplet ejected from the nozzle 511, serves as a cylindrical rod 522a to disperse the colliding water droplet outward. Other crushing forks 522
Are rectangular in cross section and have irregular lengths so that they are alternately arranged densely. This is because the water droplets repeatedly collide with many crushing forks 522 to mist the water droplets. In the illustrated embodiment, the cross section is rectangular, but it is sufficient if it is rectangular, so that it can have an appropriate shape such as a triangle, a trapezoid, or a pentagon.

At least, if the crushing forks 522 have a rectangular cross section, they will collide with a wide surface, and by arranging them in a staggered manner, the formation of mist of water droplets is promoted. In the comparison between the round type and the square type of the crushing fork 522, the square type detected the anion emission amount of 25% more than that of the round type. The reason why the lengths of the crushing forks are not uniform is that the amount of generated anions is increased by about 1.5% when the number of rotations of the motor 53 is reduced as compared with a uniform type. The scattered water droplets collide with the back surface of the disc 521 of the crushing means 52, and the water droplets bounced by the crushing fork 522 located on the outer peripheral side are the water tank 1.
It will also collide with the surrounding wall of No. 4.

Next, the flow of the outside air introduced will be described. Although a suction port 11 is provided in the lower portion of the main body 1, a filter is provided to capture a large amount of dust or the like, although not shown in the drawings. As the filter, it is possible to use a so-called bio filter (an antibacterial deodorant system in which natural components encapsulated in 2 micron microcapsules diffuse into the air to include malodorous molecules and neutralize and decompose to neutralize odors). desirable. A blower 6 made of a sirocco fan or the like is provided below the drain tank 15 and above and below to introduce outside air and to cool the motor 53 of the mist generator 5 by air. A duct 7 is circulated from the blower 6 to the upper part of the water tank, and an elbow pipe 71 is arranged so that an open end of the duct 7 faces the water tank 14.

The inner lid 2 provided with the cyclone cylinder 21 is doubled to receive the air introduced from the duct 7 and has an opening 22 on the mist generator 5. The introduced air descends from the opening 22 into the water tank 14 and passes through the water droplets generated by the mist generator 5 and the mist, whereby bacteria and dust,
The odor and impurities are removed to clean the air, and the cations are charged in water droplets and mist, thereby generating a large amount of anions. This cyclone cylinder 2
As shown in FIGS. 2, 6 (a), 6 (b), and 6 (c), 1 is composed of a receiving portion 211 and a chimney-shaped tubular body 212 that are successively reduced in diameter from an inlet 211 a facing the mist generator 5. In the chimney-shaped cylindrical body 212, spiral blades 212a are provided to raise the received mist and air in a spiral shape. In this cyclone cylinder 21, the cylindrical body 21 ahead of the reduced diameter part
Within 2, the speed will increase and the mist will increase. At this time, the mist having a large particle diameter is shaken, adheres to the inner wall of the chimney-shaped cylindrical body 212 as water droplets, and is guided to the water tank 14. Therefore, the lower end of the cyclone cylinder 21 is immersed in the water tank 14. The cations existing in the outside air are charged with mist and water droplets having a large particle size, and the water tank 1
A large amount of anions will be discharged from the cyclone cylinder 21 by being confined in the water inside 4. In this way, the inner lid 2
The ultrafine mist and anions of approximately 0.3 μm or less that have passed through the cyclone cylinder 21 are discharged into the room or the like from the air outlet 31 provided in the upper lid 3.

The amount of anions generated in the apparatus according to this embodiment is as shown in the following table, which is more than five times that of the conventional apparatus in FIG. 7 (stable at about 85,000 / cc, room temperature 25 ° C., humidity 60).
%) Could be obtained. The ion detector was tested by MODL83-100B manufactured by Dan Scientific Co., Ltd.

According to the first aspect of the present invention, since the pumping vanes composed of a plurality of projections are formed in the pumping cylinder in the axial direction, a water channel is formed in the pumping cylinder that is lifted by centrifugal force, and the amount of water is reliably ensured. Increasingly, the rising water will be ejected from the upper nozzle of the trumpet shape having an increased diameter. Further, since the crushing forks of the crushing means have a rectangular cross section and are alternately arranged densely, a large amount of mist is surely generated when almost all water ejected from the nozzle collides with the crushing fork. In addition, since a filter for removing dirt from the outside air is provided to introduce air, the progress of dirt in the water in the water tank is delayed, and the interval for water replacement work can be increased.

According to the second aspect of the invention, the motor is arranged in the lower portion of the water tank, and the output shaft of the motor is passed through the pumping cylinder to be fixed to the disk of the crushing means. Therefore, a pump for raising the water is not necessary. Also, the device could be made compact. According to the invention of claim 3, in the crushing fork vertically provided around the crushing means, by providing the cylindrical rod which faces the nozzle and collides and disperses the water droplets ejected from the nozzle, the water droplets are widely dispersed and the external crushing is performed. The collision with the fork causes more mist generation and further miniaturization. In addition, by making the lengths of the fracturing forks having a rectangular cross section uneven, the chances of water droplets colliding with the fracturing forks increase. In the invention of claim 4, the cyclone cylinder is arranged so as to face the crushing means of the mist generator, and the ultrafine mist is blown out together with the anions and the mist having a large particle size is returned to the water tank. Since the water is discharged from the tank, the water consumption in the tank is reduced, which contributes to the downsizing of the tank.
