Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a negative ion air generator having air cleaning and humidifying functions.

0002

[Prior Art] Floating in the atmosphere are soot, sulfur dioxide gas, or carbon dioxide gas emitted from factory chimneys, road dust from automobile driving, exhaust gas, and smoke, as well as other bacteria, water droplets, and various gases. of substances pollute the air. These air pollutants are increasing with the development of industry, and are having a major impact on the living environment.

[0003] For example, before the era of high industrial growth, it was common practice to purify indoor air by opening windows and letting outside air into the room, but recently it has become common practice to open windows and let outside air in. In fact, there are more cases of indoor contamination. Therefore, recently people are trying to improve their living environment by closing the windows and installing air conditioners, air purifiers, humidifiers, etc.

0004

[Problems to be Solved by the Invention] However, living environment improvement devices such as air conditioners and the like that are currently in widespread use each have advantages and disadvantages. In other words, heating and cooling equipment merely controls the temperature of the air, but does not have sufficient performance in removing pollutants. Furthermore, although air purifiers have the function of removing pollutants floating in the air, they have the disadvantage that they cannot control the humidity in the air. Furthermore, humidifiers cannot remove pollutants floating in the air, and the water particles supplied may be large enough to make the room damp. In particular, when these heating and cooling devices, air purifiers, and humidifiers are used, there is a problem in that they reduce negative ions in the air.

[0005] The negative ion concentration in the air is the amount of aggregates of electron-bearing molecules (mostly oxygen molecules), and oxygen molecules in the air usually consist of 16 electrons, 16 protons, and neutrons. , remains electrically neutral. Number of electrons is 1
When there are more than 6 ions, it becomes a negative ion.

It is said that a large amount of negative ions in the air is effective in alleviating chronic diseases such as fatigue, malaise, stiff shoulders, eye strain, stress, headaches, asthma, rheumatism, neuralgia, skin diseases, and heart disease. Many clinical cases have been reported. Specifically, negative ion generators (ionizers) are used as medical devices for regulating autonomic nerves, and are also used as beauty devices for activating cells and promoting cell metabolism.

However, conventional negative ion generators only physically and electrically ionize the air, such as by using corona discharge, and remove pollutants floating in the air. There is a problem with the lack of functionality and the ability to provide appropriate humidity to the air.

The present invention was developed based on the above circumstances, and its purpose is to provide a negative ion air generation system which has a relatively simple structure and has the functions of removing air pollutants and humidifying the air. The aim is to provide equipment.

Another object of the present invention is to provide a negative ion air generating device which has the function of removing air pollutants and the function of humidifying the air, and can further adjust the humidity.

0010

[Means for Solving the Problems] In order to achieve the above object, the present invention includes a mist chamber installed in a housing provided with an air intake port and an air discharge port, and a rotating plate rotated by a motor in the mist chamber. water is poured into this rotary plate from the water supply means, this water is atomized by being scattered around by the centrifugal force caused by the rotation of the rotary plate, and the air taken in from the air intake port is brought into contact with the fine particles of this water. The method is characterized in that negative ion air is generated by causing negative ion air to be generated, and this negative ion air is supplied from the air discharge port.

[0011] Furthermore, in order to achieve the above-mentioned other objects, the present invention provides an air intake port and an air discharge port in the housing,
A filter is provided at this air inlet, and a discharge fan is provided at the air outlet, and outside air is introduced into the housing through the filter at the air inlet, and a mist chamber is installed in this housing, and this mist chamber is driven by a motor. A rotating rotary plate is provided, water is poured into the rotary plate from a water supply means, the water is atomized by being scattered around by the centrifugal force generated by the rotation of the rotary plate, and the fine particles of this water are fed from the air intake port. Negative ion air is generated by contacting a part of the air taken in, this negative ion air is mixed with the rest of the air introduced from the air intake port, and means is provided to control this mixing ratio, and this mixed air is The air is supplied from the air outlet by the air discharge fan.

0012

[Operation] According to the first aspect of the present invention, when water is scattered around by the centrifugal force caused by the rotation of the rotating plate, this water is split in the air and becomes atomized. At this time, negative ions are generated in the nearby air, and the atomized water takes on a positive charge equivalent to the negative ions. This phenomenon is known as Leonard's effect.
It is also called the waterfall effect because there are large amounts of negative ions in the air near waterfalls. These water particles capture pollutants in the air, mix with the air, provide appropriate moisture, and generate negative ions in the surrounding area, so when they are supplied from the air outlet, the air It purifies, humidifies, and contains a large amount of negative ions.

According to the second aspect of the present invention, part of the air introduced into the housing is guided to the mist chamber and becomes moist negative ion air, and the rest is not introduced to the mist chamber and is Negative ion air containing moisture and air not containing moisture are mixed and supplied from an air outlet by a discharge fan. Therefore, the humidity ratio can be controlled by adjusting the ratio of the negative ion air containing moisture to the air not containing moisture using the control means.

[0014]

Embodiment The present invention will be explained below based on a first embodiment shown in FIG.

In the figure, reference numeral 1 denotes a housing, and an air intake port 2 and an air discharge port 3 are provided on the front surface. The air intake port 2 is provided with a filter 4 that captures relatively large dust and dirt in the air. Inside the housing 1, a water tank 5 and a mist chamber 6 are housed as water supply means.

The water tank 5 stores a predetermined amount of tap water, and the water in the water tank 5 is supplied to the mist chamber 6 through pipes 8 and 9 by a pump 7 as a water supply means. There is.

For example, two upper and lower rotary plates 10 and 11 are accommodated in the mist chamber 6 in a horizontal state. These rotating plates 10 and 11 are attached to a vertical rotating shaft 12, and this rotating shaft 12 is rotated by a motor 13 installed on the ceiling of the mist chamber 6. The rotation of the motor 13 is transmitted to the rotating plates 10 and 11 through the rotating shaft 12, and these rotating plates 10 and 11 continuously rotate at a predetermined number of rotations in a horizontal plane, respectively.

The pipes 8 and 9 are connected to these rotating plates 10 and 1.
1 and supplies water to the center of these rotary plates 10 and 11. The water dropped onto the upper surfaces of the rotating plates 10 and 11 is scattered around by the centrifugal force caused by the rotation of the rotating plates 10 and 11, and this scattering causes the water to be crushed and pulverized into fine particles. Therefore, fine mist is generated within the mist chamber 6.

An inlet 14 is provided on the ceiling of the mist chamber 6.
is open, and an exclusion port 15 is formed on the bottom surface. Air is introduced from the introduction port 14, and the air and the mist are mixed within the mist chamber 6. During this mixing, various substances contained in the air, such as dust,
Dust, soot, various gases, bacteria, water droplets, etc. adhere to the mist.
Or mist adheres to it. Further, water droplets that are not crushed into fine mist in the mist chamber 6 and water droplets that adhere to the chamber wall and are transmitted are returned to the water tank 5 through the discharge port 15.

An inlet 1 is provided in the lower side wall of the mist chamber 6.
A duct 16 having a cross-sectional area larger than the opening area of No. 4 is connected, and this duct 16 has a meandering passage section 17 as a steam/water separation section in the middle. This meandering passage section 1
At 7, there is a baffle plate 18 that obstructs the passage of the mist mixed air.
...is being formed.

A fan 20 rotated by a motor 19 is provided at the outlet of the duct 16.
The air inside the duct 16 is forcibly sucked out by the drive of
The air is sent out to an air outlet 3 of the housing 1. The operation of the negative ion air generator having such a configuration will be explained.

When the fan 20 is operated by the motor 19, the inside of the duct 16 becomes negative pressure, and outside air is introduced from the air intake port 2 formed on the front surface of the housing 1, and this outside air is introduced from inside the housing 1 through the introduction port 14. Introduced into the duct 16. This air is sent out to the outside from an air outlet 3 formed on the front surface of the housing 1. When the outside air introduced from the air intake port 2 passes through the filter 4, relatively large substances contained in the air are captured by the filter 4 and removed. Therefore, relatively small dust, soot, various gases, bacteria, water droplets, etc. contained therein are introduced into the duct 16 along with air.

At the same time as this operation, the pump 7 and motor 13 are operated. Then, the water in the water tank 5 is supplied to the center portions of the rotary plates 10 and 11 via the pipes 8 and 9, and the rotary plates 10 and 11 are rotated at a predetermined speed.

The water dropped onto the rotating plates 10 and 11 is scattered around by the centrifugal force caused by the rotation of the rotating plates 10 and 11, and this scattering causes the water to be crushed and pulverized into fine particles. Therefore, fine mist is generated within the mist chamber 6, and this mist is mixed with the air introduced from the introduction port 14. Due to this mixture, dust, dust, soot and smoke contained in the air,
Various gases, bacteria, water droplets, etc. adhere to the mist, or the mist adheres to these substances.

When this adhesion effect is repeated and the mass of the mist and air pollutants increases, these mist and air pollutants fall to the bottom of the mist chamber 6. This effect is effective because the mist of relatively large particles is subject to gravity.

Also, relatively large water droplets that have not been crushed in the mist chamber 6 and water droplets that have adhered to the chamber wall collect at the bottom of the mist chamber 6, and are returned to the water tank 5 through the discharge port 15.

That is, when air and mist are mixed in the mist chamber 6, the pollutants and the mist stick together and fall due to gravity, and are discharged from the discharge port 15 into the water tank 5. Has a purifying effect.

Furthermore, when the water is split in the air and atomized in the mist chamber 6, negative ions are generated in the nearby air, and the air is negatively ionized due to the so-called Lennard effect. In other words, a large amount of negative ions are generated within the mist chamber 6.

[0029] Such a mixture of negatively ionized air and mist is drawn into the duct 16. These mist and air pass through a meandering passage 17 as the air/water separation part of the duct 16.
When passing through the duct, the mist of large particles with relatively high kinetic energy adheres to the duct wall by colliding with the wall of the curved passage, being subjected to wall resistance, and colliding with the baffle plate 18... Most of the components flow along the walls of the curved passage and are dropped into the water tank 5 through the discharge port 15. Although the amount of water returned to the water tank 5 varies depending on the surrounding environment, the amount of water returned to the water tank 5 is 99% of the amount pumped up by the pump 7.
This corresponds to more than 7%.

For example, in air with a humidity of 50% or less, it is said that it is good to supply about 400 cc of water per hour. 99.83%, and in air with a humidity of 70% or more, it is said that it is best to supply 200 cc or less of moisture per hour. In this case, the water returned to the water tank 5 is pumped by the pump 7. This corresponds to 99.92% of the amount raised. The amount of mist mixed with air thus supplied can be controlled by the temperature of the water in the water tank 5 and the temperature of the air.

The water returned to the water tank 5 has dust, dirt, soot, various gases, bacteria, water droplets, etc. contained in the air attached to it, and therefore the impurities contained in the air are removed from this water. will be removed.

The air and mist that have reached the outlet of the duct 16 as described above are in a clean state from which dust, dirt, soot, various gases, bacteria, water droplets, etc. contained in the air have been removed. Furthermore, in the case of mist, the particle size is extremely small, and the air also contains a large amount of negative ions. Such air and mist are sent out to the outside from an air outlet 3 formed on the front surface of the housing 1.

[0033] As mentioned above, the air at this time is good for health because air pollutants have been removed, it contains appropriate humidity (mist), and a large amount of negative ions are present.

That is, the device of the above embodiment performs an air purifying function, a humidifying function, and a negative ion generation function, and this is because water is scattered in the mist chamber 6 by the centrifugal force caused by the rotation of the rotary plates 10 and 11. This method utilizes the Lennard effect by crushing, pulverizing, and atomizing water by this scattering, so it has a simple structure and achieves the above 3.
Can perform two functions at the same time. Experiments using the negative ion air generator shown in the above embodiment will be explained.

[0035] Water at a temperature of 20° C. is pumped through the pump 7 at a rate of 4.3 liters/min, and the rotating disk 10 with a diameter of 200 mm is
When the rotating disks 10 and 11 are rotated by the motor 13 at 2900 rpm, the average particle size is 0.2.
It was observed that mist of 8 μm was generated.

[0036] The number of fine particles with a size of 0.1 to 0.5 μm is more than 1 million per 0.01 cubic foot, and although fine particles with a size of 0.1 μm or less cannot be measured, it is believed that the number is considerable. Guessed.

[0037] As mentioned earlier, 4.3 liters/
Not all of the water supplied at a rate of min is sent out from the air outlet 3, and the water actually used as humidity is 1/1000 to 1/10,000 of that amount. The negative ions released from the air outlet 3 of the housing 1 are
The number of positive ions is 60,000/cc or more, and the number of positive ions is 200/cc.
It was around cc.

[0038] The number of negative ions varies depending on weather conditions, air pollution, etc., and on average there are 2000 to 3000 in mountainous areas.
It is said that positive ions exceed negative ions in shopping and industrial areas, and 400 to 600 ions/cc in general residential areas. In contrast, it can be seen that the function of the negative ion air generator of the present invention is significantly superior.

In the above embodiment, the water is temporarily stored in the water tank 5, and the water is supplied to the rotary plates 10 and 11 by the pump 7. good. In this case, of course, the flow rate is controlled. Further, the rotating plates 10 and 11 are not limited to rotating horizontally, but may be rotated diagonally or vertically. Furthermore, the moisture that collects at the bottom of the mist chamber 6 may be disposed of outside instead of being returned to the tank 5. Furthermore, the steam/water separation portion following the mist chamber 6 may be of a fin type as in the second embodiment shown in FIGS. 2 and 3.

[0040] This fin-type steam/water separation section has duct 1
A rotating fin 30 is provided in the middle of 6, and this rotating fin 30
The blades are angled so that they are automatically rotated by the flow of air sucked in by the fan 20, that is, by the wind. Therefore, when air containing mist is introduced, when this air passes through the rotating fins 30, the rotating fins 3
0 is turned, and as a result, the mist with large particles is blown to the outer periphery by centrifugal force, adheres to the duct wall, travels along the wall, and is dropped into the water tank 5 from the exhaust port 15, and the fine mist is sent to the center along with the air. It is sent to the fan 20 side through the duct 16a. Even in this case, mist with large particles can be separated.

[0041] In addition to the baffle plate method and fin method described above, the steam/water separation section uses a cyclone method to swirl air containing mist and separate mist with large particles using centrifugal force. is also possible.

Furthermore, if it is desired to control the humidity of purified air discharged indoors to a low level, a negative ion air generator having a structure as shown in the third embodiment shown in FIG. 4 may be used.

In this case, the air intake port 2 of the housing 1
A part of the outside air introduced through the filter 4 installed in the mist chamber 6 is introduced into the mist chamber 6. Through the mist chamber 6 and the duct 16, the air is purified in the same manner as in the first or second embodiment, provided with negative ions, and moistened, and is discharged into the interior of the housing 1 by the suction fan 40. A discharge fan 45 is installed at the air discharge port 3 of the Housong 1.
is provided, and this discharge fan 45 is connected to the filter 4.
The remainder of the outside air introduced through the housing 1 is removed by the suction fan 40 through the mist chamber 6 and the duct 16.
The mixed air is mixed with the purified air discharged into the room, and the mixed air is discharged into the room from the air discharge port 3.

In this case, both the suction fan 40 and the discharge fan 45 are fans whose air volume can be adjusted, and by controlling the air volume, the air purified through the filter 4 and the purified air that has passed through the mist chamber 6 with negative ions added to it can be separated. The mixing ratio with air can be adjusted, and since the purified air to which negative ions have been added through the mist chamber 6 contains moisture, the proportion of moisture in the purified air returned indoors from the discharge fan 45 is reduced. be able to.

In the case of the third embodiment shown in FIG. 4, the mixing ratio between the negative ion air containing moisture and the purified air containing no moisture can be controlled mainly by adjusting the air volume of the suction fan 40. However, the present invention is not limited to this, and other mixing ratio adjusting means such as adjusting the opening area of the inlet of the mist chamber 6 or adjusting the opening area of the outlet of the duct 16 may be used.

[0046]

[Effects of the Invention] As explained above, according to the first aspect of the present invention, water is scattered around the surrounding area by the centrifugal force caused by the rotation of the rotary plate in the mist chamber, and this water is split in the air and atomized. At this time, negative ions are generated in the nearby air due to the Lennard effect. The above-mentioned fine water, or mist, is mixed with the air introduced into the mist chamber, and due to this mixing, the mist captures pollutants in the air and has a purifying effect. In addition, as mentioned above, it generates negative ions, so the air supplied from the air outlet is purified, humidified, and contains a large amount of negative ions, improving the air environment. can be brought into good condition. Moreover, this device has a simple configuration because it performs the three functions of air purification, humidification, and negative ion generation by scattering and atomizing water through the rotation of the rotary plate housed in the mist chamber. .

Further, according to the second aspect of the present invention, a part of the air introduced into the housing is guided to the mist chamber and becomes negative ion air containing moisture, and the rest is not introduced to the mist chamber and the moisture is Since the negative ion air containing the negative ion air and the air containing no moisture are adjusted by the mixing ratio control means and supplied from the air outlet by the discharge fan, the humidity ratio can be controlled.
