The present invention relates to an air cleaner having a negative / positive ion generator, and more particularly, does not generate secondary pollutants that are harmful to the human body, and also generates a large amount of anions and cations by electron radiation without causing discharge noise. By dissipating evenly throughout the inside of the vehicle, the air with negative / positive ion generator that can remove odors and various harmful substances contained in the air and exhibit sterilization effect and keep the environment inside the room always comfortable. It relates to a purifier.

In recent years, as the number of vehicles owned increases and the atmospheric environment becomes worse, the desire to keep the interior of the automobile in a comfortable state has gradually increased.

In general, when driving a vehicle, bacterial particulates such as dust, dust, and pollen generated on the road, and various harmful substances such as sulfurous acid gas (SO ₂ ), nitrogen compound (NO _X ), and carbon monoxide (CO) present in contaminated air This will flow into the interior of the car. In particular, when the heater or air conditioner is operated on a cold or wet day, odors and bacterial particles generated at this time are introduced into a differential vehicle called a cabin (Cabin) as it is, causing discomfort to a driver or a passenger.

Accordingly, the air conditioner for automobiles is equipped with an air filter for supplying purified air to a driver or a passenger by preventing the above-mentioned bacterial particulates or harmful substances from entering the vehicle interior.

1 is a view schematically showing the interior of a general automotive air conditioner.

As shown in FIG. 1, a general vehicle air conditioner includes an air inlet 101 or an outdoor air inlet 102 according to an opening / closing selection of an indoor / outdoor air conversion door 103. A blower unit 104 for selectively suctioning into the 100, an evaporator 106 for cooling the air blown from the blower unit 104 by driving the electric motor 105, and the evaporator The heater core 107 is installed adjacent to the 106 to heat the air, and the temperature of the air discharged into the cabin according to the opening and closing angle between the evaporator 106 and the heater core 107. Temp doors (Temp Door) for adjusting the number of, and in order to discharge the air cooled or heated according to the selection of opening and closing of the door (108) to each part of the interior, a plurality of connected to each part of the interior Vents 109, 1110, and 111 And a plurality of mode doors (Mode Doors 112, 113, 114) for selectively changing the flow direction of the air discharged through the vents (109, 110, 111).

In the vehicle air conditioner configured as described above, the evaporator 106 through which the refrigerant flows through the temporal door 108 through the air sucked into the air conditioning case 100 by the driving of the electric motor 105 of the blower unit 104. Or heat exchange by selectively passing through the heater core 107 through which the coolant of the vehicle engine flows, and then through the vents 109, 1110, and 111 connected to the respective parts of the vehicle interior in a cold or warm state. By distributing to the air conditioner, the heating and cooling of the vehicle interior is achieved.

In the vehicle air conditioner as described above, in order to purify the air flowing into the vehicle cabin, the air inlet 101 side, upstream side of the blower unit 104 or between the blower unit 104 and the evaporator 106 (Air) Filter, 115) is fixed.

Examples of the air filter 115 include a dust removing filter for filtering bacterial fine particles such as dust, an odor removing filter for removing odor components such as odor, and an integrated filter integrating the dust removing filter and odor removing filter. There is. Among them, the odor removing filter or the integrated filter is configured to physically adsorb and filter harmful substances in the air using activated carbon particles, for example, in order to deodorize or deodorize in an air inflow mode or an air circulation mode. It is.

However, the filter as described above, when a certain period of use has elapsed, the odor component is adsorbed and trapped in the fine pores of the activated carbon to reach the saturation state, the odor adsorbed in the high temperature state by gradually losing the adsorption power of the filter Partial re-emission of the components into the interior of the vehicle may eventually cause discomfort to the occupant. In particular, when driving in a state in which the interior is sealed with the outside during the rainy season in summer, the adsorption power of the filter is limited due to the high temperature air flowing from the outside air, and the odor component adsorbed on the filter surface is easily desorbed, thereby operating the air conditioner. There was a problem that the air cleanliness in the interior is greatly reduced as the bad smell is introduced into the vehicle interior.

Moreover, such a filter can only perform a function of simply filtering irrespective of the air purifying state in the cabin intended by the driver or the passenger, and thus there is a problem in that the air in the cabin cannot play any role.

Accordingly, the driver or passenger frequently opens a window to ventilate the air, or separately installs an air cleaner in an appropriate position in the cabin, for example, an instrument panel in front of the vehicle or a shelf behind the rear seat of the vehicle. Purifies the air inside the car.

In recent years, in consideration of health aspects, there is a tendency to use a lot of air cleaners that can release negative ions beneficial to the human body in the vehicle interior.

2 shows an example of such an air cleaner.

As shown in FIG. 2, the air purifier includes a case 200 having an air inlet 201 and an air outlet 202, and air installed at an air inlet 201 in the case 200. A filter 203, a blowing fan (not shown) rotatably installed in the case 200, and an air discharge port installed in the case 200 via the air filter 203 from the air inlet 201 ( And a negative ion generator for generating negative ions to purify the air flowing to the side 202).

As shown in FIGS. 3A and 3B, the negative ion generator sets the needle-shaped discharge electrode 210 as the negative electrode and the ground electrode 211 opposite thereto as the positive electrode. A high DC voltage is applied between the 210 and the ground electrode 220 to generate a corona discharge between the anodes, thereby releasing a large amount of electrons into the air. A large amount of electrons emitted in this manner collides with oxygen and moisture in the air and anionizes the oxygen and moisture to purify the air.

However, such an anion generator generates ozone (O ₃ ), which is highly oxidative in generating negative ions and has a harmful effect on the human body, due to the silent discharge in which discharge occurs between the anodes by applying a high voltage as described above. Resulted.

The basic reaction equation for ozone generation by the silent discharge is as follows.

^{_{O 2 + e - → O +}} O + e -

O + O → O ₂

O + O ₂ + M → O ₃ + M

O ₂ + O ₂ → O ₃ + O

As described above, oxygen is generated by discharge of ozone, and the generated ozone is reduced to oxygen by working with pollutants. When used as an oxidant, such ozone leaves no harmful residues at all, and has a strong sterilizing power to remove bacteria and viruses, and to have a strong bleaching effect, as well as organic substances such as cigarette smoke and other odorous gases and various harmful substances. It reacts with and has the effect of harmlessness, but also causes harmful effects on the human body.

This ozone has a serious effect on children, the elderly, and heart patients, and one of the dangerous gases that the increase of 0.1ppm ozone increases the number of deaths by 7%. For this reason, each country is strongly regulated by specifying the allowable concentration of ozone.

As described above, the conventional negative ion generating air cleaner has a problem of generating negative ions at the same time by silent discharge and inevitably generating ozone which is a byproduct. In this case, rather less anion is generated, there is a problem that can not fully exhibit the effect of air purification in the originally intended vehicle interior.

On the other hand, Japanese Patent Laid-Open No. 2005-71715 has a negative / positive ion generator for purifying air by generating positive ions in addition to the negative ions based on the fact that only negative ions can effectively remove suspended bacteria in the air. An adjusting device is disclosed.

Figure 4 schematically shows a cross-sectional view of the air conditioner with a negative / positive ion generator according to the prior art described above.

As shown in Fig. 4, the negative / positive ion generator 306 according to the prior art is provided on the downstream side of the blowing fan 301 inside the air conditioner 300, and has a flat plate dielectric 302. And a grounding electrode 303 and an applying electrode 304 facing each other with the dielectric 302 interposed therebetween, and a voltage applying means 305.

The prior art is to purify the air using a negative / positive ion generator having such a structure. That is, when the voltage of the positive electrode and the negative electrode is alternately applied to the applying electrode by the voltage applying means, the dielectric 302 causes polarization to generate plasma discharge in the air layer in contact with the ground electrode. Accordingly, a plasma region is formed near the ground electrode to ionize or dissociate water molecules or oxygen molecules in the air to generate anions (O ₂ ⁻ ) and cations (H ₃ O ⁺ ), and the generated anions and cations are supplied to the blower fan. Air is blown to the proper space, and various kinds of fungi, harmful substances and odors suspended in the air are enclosed in the form of clusters to make the air clean.

However, since the negative / positive ion generator according to the related art is a plasma discharge method for directly discharging plasma in the air by using a ceramic chip as a dielectric, there is a problem in that discharge noise is generated, and in addition, air purification efficiency in a small area. While this is high, there is a problem that air purification efficiency is low in a large area.

In particular, secondary discharges such as ozone (O ₃ ) and nitrogen oxides (NO _x ), which are harmful to the human body as the generated ion reacts with the active oxygen (O ⁺ ) in the air as well as the amount of generated ions less. , there is a problem that results in the opposite effect by ^-: (+ O ⁺ O ₃ → O ₂ for example) to occur.

Accordingly, the present invention has been made to solve the above conventional problems, and does not generate secondary pollutants harmful to the human body, and also generates a large amount of anions and cations by electron radiation without causing discharge noise. Its purpose is to make it evenly distributed throughout the room, to remove odors and various harmful substances contained in the air, and to maintain a comfortable environment at all times by exhibiting a sterilizing effect.

(First embodiment)

In this embodiment, the cluster negative / positive ion generator according to the present invention is applied to the air inlet of the vehicle air cleaner.

5 and 6, the air purifier according to the present invention includes a case 10 having an air inlet 11 and an air outlet 12, and an air inlet 11 in the case 10. It is comprised by the air filter 13 which is installed in the side and adsorbs and removes a foreign material in the air which flows in by the drive of the blower fan 14 (refer FIG. 8). Here, the case 10 may be installed at a predetermined place in the vehicle interior, for example, an instrument panel in front of the vehicle or a shelf behind the rear seat of the vehicle.

In the air purifier having such a structure, the present invention sterilizes the interior air by discharging the anion and the positive ions to the air flowing into the air inlet 11 by the driving of the blower fan 14 through the air outlet The cluster negative / positive ion generator 20 (refer to FIG. 6) is installed on the air flow path of the air inlet 11 so as to clean and create a comfortable indoor environment.

Here, unlike the conventional corona discharge method or the plasma discharge method, the cluster negative / positive ion generator 20 according to the present invention is provided with a pair of discharge electrodes having a positive electrode and a negative electrode, and then atmosphere. An electrospinning method is adopted in which electrons are discharged from the discharge electrodes using a dielectric material. That is, the cluster negative / positive ion generator applies a high voltage pulse (a high voltage but a small amount of energy) to a pair of discharge electrodes to radiate electrons directly in the air, thereby radiating the emitted electrons without any noise in the air. And it is an ion generator that combines with moisture and generates a large amount of cluster anions and cations and does not generate secondary pollutants such as ozone and nitrogen oxides that are harmful to the human body.

6 (a) and 6 (b) show the structure of the cluster negative / positive ion generator as viewed from the bottom. As shown in FIGS. 6 (a) and 6 (b), the cluster negative / positive ion generators are formed on the high voltage generator 21 and the side portions of the high voltage generator 21 for generating a high voltage pulse, respectively. A main body 23 having fastening portions 22 (only two are shown in the figure) having fastening holes 22a; A power input unit 24 including negative (-) poles 24a and positive (+) poles 24b connected to one end of the high voltage generator 21, respectively; The high voltage generator 21 includes a pair of discharge electrodes 25 and 26 connected to one side of the lower surface of the high voltage generator 21.

The power input unit 24 can be electrically connected to a control switch provided in the instrument panel in the vehicle compartment to appropriately control the generation of negative ions and positive ions. Alternatively, the power input unit 24 may be connected to the start switch IGN to continuously generate negative ions and positive ions when the vehicle is started.

The pair of discharge electrodes 25 and 26 may generate the cluster anion by a large amount of electrons discharged by the high voltage pulse applied from the high voltage generator 21 through the power input unit 24. A first high voltage output line 25a connected to the generator 21 and a first negative voltage generator 25b having a metal fiber shape composed of an alloy of various metal components at the end of the first high voltage output line 25a; Discharge electrodes 25; And a predetermined distance from the first high extruding force line 25a to generate cluster cations by a large amount of electrons discharged by a high voltage pulse applied from the high voltage generator 21 through the power input unit 24. A cation generator having a metal fiber shape composed of an alloy of various metal components at the end of the second high voltage output line 26a and the second high voltage output line 26a connected to the high voltage generator 21 with (d). It consists of the 2nd discharge electrode 26 which consists of 26b.

The anion generator 25b and the cation generator 26b each have a brush shape in order to widen the surface area of the discharge, and generate anions and cations according to the voltage size of the high voltage generator 21. You can control the enemy.

Here, it is preferable that the interval d between the second discharge electrode 25 and the second discharge electrode 26 is maintained in the range of 2 to 5 cm in consideration of electrical safety, bactericidal (or antimicrobial), and ion generation amount. If the distance d is less than 2 cm, there is a risk of sparks due to contact between brushes when ions are generated from the anion generator 25b and the cation generator 26b. In addition, when the interval d exceeds 5 cm, ions generated from the anion generator 25b and the cation generator 26b are widely dispersed, resulting in a decrease in sterilization. Preferably, the distance d between the first discharge electrode 25 and the second discharge electrode 26 is 3 cm.

In order to evaluate the bactericidal power of the test strain according to the interval between the discharge electrodes, after spraying a certain amount of Aspergillus niger or Escherichia coli as the test strain in the test vessel of 500mm × 700mm × 500mm The internal air was collected by time, and the collected air was incubated, and then the residual ratio of the test strain was measured by the cluster negative / positive ion generator. At this time, 12V power was applied to the cluster negative / positive ion generator.

7 shows the results.

First, Figure 7 (a) shows the sterilization power according to the operating time of the cluster negative / positive ion generator when using the mold as a test strain, Figure 7 (b) shows the cluster negative when using E. coli as the test strain It shows the sterilizing power according to the operating time of cation generator.

As can be seen from FIGS. 7A and 7B, when the distance d between the first discharge electrode 25 and the second discharge electrode 26 is 3 cm, the sterilizing power is excellent. have. This means that making the distance d between the first discharge electrode 25 and the second discharge electrode 26 as small as possible is advantageous in terms of efficiency of sterilizing power.

Meanwhile, a circular first opening 20a-1 and a first opening 20a-1 are formed on the lower surface of the high voltage generator 21 in which the first high voltage output line 25a and the second high voltage output line 26a are provided. The opening part 20a which consists of the 2nd opening part 20a-2 extended in the horizontal direction is formed in the both sides of (). At certain portions of the first high voltage output line and the second high voltage output line, a cylindrical body 27a corresponding to the shape of the first opening 20a-1 may be locked to the opening 20a in a rotatable manner. Locking portions 27 having upper and lower wing portions 27b and 27c projecting in the horizontal direction corresponding to the second opening portion 20a-2 at regular intervals on both sides of the cylindrical body 27a, respectively, are provided. It is characterized by being provided integrally.

As a result, the locking portion 27 arranges the wing portions 27b and 27c in a direction parallel to the second opening 20a-2, and the lower wing portion 27c of the wing portions 27b and 27c. After the bay is inserted into the high voltage generator 21 and rotated by 90 ° as shown in Fig. 6 (a), the lower surface of the upper wing 27b of the wing 27b, 27c is It is fastened by being supported on the upper surface of the high voltage generator 21. In addition, when the locking portion 27 is reversed in the above-described operation, the locking portion 27 can be released from the opening 20a as shown in FIG.

The reason for providing the locking portion 27 having such a structure is that when the anion generating portion 25b and the cation generating portion 26b are to be installed at a position for air purification, a predetermined length is provided above the locking portion 27. In the case where the first high voltage output line 25a and the second high voltage output line 26a each have a short length and are difficult to be installed at the position, the locking portion 27 is released as described above, so that the high voltage generating portion 21 is released. The extra first high voltage output line 25a and the second high voltage output line 26a which are accommodated are taken out to adjust the length appropriately.

In the present invention, the anion and the cation are generated simultaneously through the anion generator 25b and the cation generator 26b installed at the air purification target position as described above, and if necessary, the anion generator 25b and the cation generator ( Only one of 26b) can be controlled to generate only anions or cations.

As described above, the cluster negative / positive ion generator 20 according to the present invention includes the positive ion of the negative electrode generator 25b of the first discharge electrode 25 and the positive electrode of the second discharge electrode 26 through the high voltage generator 21. By applying electrical energy to the generator 26b, electrons are radiated to the air over a large surface area of the anion generator 25b and the cation generator 26b while being combined with oxygen and moisture in the air to generate a large amount of cluster anions. To generate. Therefore, harmful substances such as various bacteria, fungus bacteria, and odors contained in the air are surely removed by such cluster anions.

Such a cluster anion and cation generating mechanism will be described in more detail as follows.

When the high voltage pulse current, which is a strong negative electric charge, is applied to the negative ion generating unit 25b of the first discharge electrode 25 through the high voltage generating unit 21 to emit electrons into the air, the electrons discharged together with the thermal energy in the air Moisture (H ₂ O) is debonded to generate hydrogen and anions as shown in Equation (1), and at the same time, air is applied by applying a high voltage pulse current, which is a strong positive electrode, to the cation generator 26b of the second discharge electrode 26. When electrons are radiated to the middle, water (H ₂ O) in the air deprives electrons and generates oxygen and cations as shown in Equation (2).

^{_{2H 2 O + e - → 4H}} + O 2 - ‥‥ (1)

^{_{2H 2 O → 4H + + O}} 2 + e - ‥‥ (2)

As described above, the anions (O ₂ ⁻ ) and cations (H ⁺ ) discharged into the air are unstable, so they combine with water molecules in the air to form cluster ions such as grape clusters, that is, H ₃ O ⁺ (H ₂ O) _n (n is any natural number) and O ₂ ⁻ (H ₂ O) _m (m is any natural number).

These cluster ions surround the harmful substances suspended in the air and chemically react with the surrounding water molecules to form active species such as hydrogen peroxide (H ₂ O ₂ ), hydrogen phosphate (HO ₂ ), or the like, as shown in equations (3) and (4). Produces hydroxy radicals (? OH).

^{_{H 3 O + (H 2 O}} ) n + O 2 -? (H 2 O) m → OH + H 2 O 2 + (n + m) H 2 O ‥‥ (3)

^{_{H 3 O + (H 2 O}} ) n + O 2 - (H 2 O) m → HO 2 + H 2 O + (n + m) H 2 O ‥‥ (4)

Hydrogen peroxide (H ₂ O ₂ ), hydrogen phosphate (HO ₂ ) or hydroxy radicals (? OH) produced in this way exhibit strong activity, and thus deprive hydrogen (H) in various harmful substances or odors in the air membranes. It is converted into water molecules (H ₂ O), at which time harmful substances and odors from which hydrogen (H) is removed from the cell membrane are destroyed by the cell membrane and are inactivated and converted into harmless substances.

As described above, the cluster negative / cation generator 20 according to the present invention generates a large amount of cluster anions, but does not generate secondary pollutants such as ozone (O ₃ ) and nitrogen oxides (NO _x ). In addition to the bactericidal effect, it is intended to continuously release air that is beneficial for the metabolic activity of the human body.

Therefore, the present invention is provided with the filter 13 installed at the air inlet 11 side by providing a cluster negative / positive ion generator 20 having the function as described above at the air inlet 11 of the conventional air cleaner. The air initially introduced into the case 10 may be purified at its source. Thus, when the cluster negative / positive ion generator 20 is installed in the air inlet 11, there is an advantage that can extend the life of the filter as well as the air purification effect. In FIG. 5, the cluster negative / positive ion generator 20 is shown in front of the filter 13 in the air inlet 11 side. At this time, the main body 21 of the cluster negative / positive ion generator 20 is partition wall 15 partitioning the air inlet 11 and the air outlet 12 by fixing means such as a screw fastened through the fastening portion 22. It is preferable that the anion generator 25b and the cation generator 26b are installed to face the front of the filter 13.

In the present invention, an example in which the cluster negative / positive ion generator 20 is installed in front of the filter 13 is described, but is not necessarily limited thereto. For example, the cluster negative / positive ion generator 20 may be installed behind the filter 13.
