Description

Negative ion generator {A NEGATIVE ION GENERATOR}

The present invention relates to an anion generator that purifies, removes bacteria, and deodorizes air by removing dust, dust, tobacco smoke, and the like in a room with a liquid.

As a conventional air purifier, it is known that it is a so-called filter type that sucks and purifies contaminated air to pass through the filter. However, if the filter type air purifier does not clean the filter frequently, the effect is immediately lowered. In addition, in order to deodorize simultaneously, the deodorant had to be used. In addition, the filter type air purifier also has a problem of generating cations deemed bad for health.

An example of an air purifying negative ion generating device in which such a problem does not occur at all is disclosed in Japanese Patent Application Laid-Open No. 60-34026. Since the anion generator cleans the contaminated air using water, it is possible to obtain the effect of removing dust and dirt, cigarette smoke, and the like even with time, and to obtain a strong deodorizing power even without using a deodorant. Furthermore, in recent years, it has been found that a large amount of negative ions generated in health are generated from this negative ion generating device. In addition, this anion may be generated by corona discharge, but in the case of corona discharge, harmful ozone is also generated.

However, the conventional negative ion generating device using water mentioned above is for purifying the whole room, such as a clean room of a factory, and was installed as an air conditioner of a factory. Therefore, even if the facility becomes too large and is attracting attention as generating anion which is good for health because it is very expensive, it is currently not used in general homes or offices.

That is, the water tank 2 is formed so that there may be no edge part over the perimeter of the inner side surface. Moreover, the straight line shown by the code | symbol L is a position of the maximum water level of the water stored in the water tank 2.

Above the water tank 2, the inner cover member 3 which can be removed from the apparatus main body 1 is provided, and the closed space which is almost divided and closed by the water tank 2 and this inner cover member 3 ( 4) is formed. In this closed space (4), a cylindrical water separator tower (5) is erected and installed through a receiving mechanism (not shown) installed at the bottom of the water tank (1). An inlet 6 for introducing air containing fine water droplets having a width of a height extending from above the maximum water level L to almost a half of the total height is formed. As shown in FIG. 2, the outer side of the inlet 6 extends outward so that the inner circumferential surface of the separation tower 5 gradually becomes a large diameter, thereby allowing air to be separated from the separation tower 5. ) Can be entered in the tangential direction.

In addition, the water tank 2 is provided with a rotating body 7 having a height reaching up above the maximum water level L as a fine water droplet forming means for forming a myriad of fine water droplets in the closed space 4. This rotating body 7 is fixed to the motor shaft 9 of the drive motor 8 arranged below the water tank 2, and in this case, the motor shaft 9 is also above the maximum water level L. It is formed to a length reaching up to, the rotor 7 is fixed at a position above the maximum water level (L). In addition, the water tank 2 is formed with a guide tube 10 surrounding the motor shaft 9 at a height reaching up above the maximum water level L, and is guided to the drive motor 8 by the guide tube 10. Prevents water from invading

In the closed space 4, in the present example, an outside air inlet 11 for introducing outside air is formed at the upper right of FIG. 1, and the outside air inlet 11 is an outside air disposed below the inclination of the driving motor 8. It is connected via the fan 12 and the duct 13 as a blowing means. This fan 12 is comprised so that it may inhale from the external air inlet part 14 formed in the front of the anion generator main body, and to exhaust it into the closed space 4 as shown in FIG.

The upper end of the separation tower (5) is covered with an inner cover member (3), an exhaust pipe (15) is formed at a position corresponding to the separation tower (5) of the inner cover member (3). The cover member 3 is provided on the cover member 3 so that the exterior cover member 16 can be detached, and the exterior cover member 16 has an exhaust outlet 17 serving as an exhaust section for discharging clean air to the outside of the apparatus. Is formed (see FIG. 3). In addition, a space 18 is formed between the inner cover member 3 and the outer cover member 16. In this space, as shown in FIG. 4, exhaust guide means for introducing air into the exhaust outlet 17 is provided. As a guide 19 is provided. In this example, the guide 19 is provided on the inner cover member 3, but it is also possible to provide the guide 19 on the outer cover member 16 side.

The bottom portion of the water tank 2 is inclined, and the bottommost position thereof is almost immediately below the water separation tower 5. The drainage hole 20 is provided in this lowest position, and the drainage tank 21 is arrange | positioned just under the drainage hole 20. As shown in FIG. An open / close valve (not shown) is provided between the drain hole 20 and the drain tank 21, and the open / close valve is configured such that the open / close valve is controlled by the operation of the valve operating motor 22.

The operation of the negative ion generating device configured as described above will be described.

In the water tank 2, for example, the water of a quantity reaching the maximum water level L is accumulated, and when the switch is turned on, the driving motor 8 and the fan 12 start to operate. Since the lower part is immersed in water, the rotor 7 rises along the outer and inner circumferences according to the rotation, and water is sprinkled almost horizontally from the upper end to the circumference. In addition, the rotor 7 is provided with an injection member 7A made of a mesh screen or the like so as to surround its surroundings near the upper end, and water scattered from the rotor 7 is further dispersed by the injection member 7A. It is sprinkled finely, and the closed space 4 can be filled with a myriad of fine water droplets.

On the other hand, when the fan 12 is operated, outside air is blown into the closed space 4 through the duct 13 from the outside air inlet 11, and the outside air contacts the myriad fine water droplets. Then, water droplets adhere to dust, dust, tobacco smoke, etc. in the outside air, and by attaching the water droplets, some weight drops to the water tank 2. In addition, when the fan 12 is operated, the pressure in the closed space 4 is increased, so that air to which water droplets adhere is introduced into the water separation tower 5 from the inlet 6. At this time, since air enters along the inner circumferential surface of the water separation tower 5 by the introduction port 6, air containing the introduced water droplets flows in a spiral shape. Therefore, in the water separation tower 5, relatively heavy water droplets attached to particles such as dust, dust, tobacco smoke, etc., by centrifugal force pass through a position close to the inner wall surface, and such particles are not attached, and even more fine water droplets Pass near the center of the tower. For this reason, the relatively heavy water droplets adhering to the particles reach the inner wall of the separation tower 5 and are trapped, and eventually fall into the water tank 2, and contain air containing fine purified water droplets free of dust, dust, and tobacco smoke. Only through the guide 19 is discharged from the exhaust outlet 17 from the exhaust cylinder 15 through the inner cover member 3 and the outer cover member 16.

The air discharged in this way not only removes dust, dust and tobacco smoke suspended in the outside air, but also contains a large amount of anions which are good for health.

By the way, it is empirically proved that this anion is generated in large quantities, so that the water used, ie, the water in the tank 2, is clean. In addition, the water in the water tank 2 cannot be avoided from being contaminated by contaminants in the outside air as it continues to be used. Moreover, when water in the water tank 2 is left for a long time, a problem arises that bacteria grow and mucus is generated.

Therefore, in the negative ion generating device of the present invention, when a predetermined time elapses, the valve operation motor 22 is automatically operated to open and close the valve, and water in the water tank 2 can be forcibly dropped into the drain tank 21. . That is, the drain tank 21 can be prevented from being left for a long time or being used for a long time by arranging the drain tank 21 below the water tank 2 and providing an opening / closing valve in the drain hole 20.

In addition, the germs in the water tank 2 propagate more as the water stagnates. For this reason, in the negative ion generating device of this embodiment, the inner periphery of the water tank 2 is formed in track shape of the continuous surface without each part, and the inside of the water tank 2 is rotated about the axis which is substantially perpendicular to a horizontal plane. A rotating body 7 is provided. By such a structure, since the water in the water tank 2 circulates without stagnation with the rotation of the rotating body 7, it can suppress the propagation of bacteria.

In addition, since the used water is dropped into the drain tank 21, the drain tank 21 can be easily removed by discharging the drain tank 21 from the apparatus body 1, and the outer cover member 16 and the inner cover member 3 can be disposed of. Also, since the water tank 2 can be easily removed from the apparatus main body 1 by removing both covers, the water tank 2 is exposed, so that water can be supplied easily. Moreover, since the whole of the water tank 2 is revealed by removing both covers, the maintenance, such as cleaning and repair, is also easy. In addition, at least one of the outer cover member 16 and the inner cover member 3 may be opened and closed via a hinge or the like to allow attachment and detachment of the main body.

According to the structure of Claim 1, since the cover member which covers a water tank is attached to the apparatus main body so that attachment and detachment are possible, supply of water, cleaning of a water tank, etc. can be performed easily.

According to the configurations of claims 2 and 3, the cover member is composed of an inner cover member and an outer cover member, and an exhaust guide means is provided between the inner cover member and the outer cover member, so that a duct or the like for guiding the exhaust gas is particularly provided. There is no need to install it.

According to the configurations of Claims 4 and 5, the fine water droplet forming means is provided with a rotating member having a lower portion in the water and an upper portion positioned above the water surface in the water tank, and the periphery of the water tank has no edges. Since it is formed in the surface to be made, it can suppress the stagnation of water in a water tank, and can suppress the propagation of a bacterium.

According to the configurations of Claims 6 and 7, a drainage part is formed in the water tank, and a storage tank capable of taking out from the anion generator body is disposed below the drainage part, and an opening / closing valve is provided in the drainage part, so that water in the water tank is periodically It is possible to exhaust the good air having a lot of anions in exchange with.
