Description

[0001] The present invention relates to an anion generation module capable of changing an electrode needle for preventing electrode deterioration,

The present invention relates to an ion generating module (or a cluster ionizer) including an ion generating element for generating positive and negative ions using a high voltage, and more particularly, to an ion generating module To a possible negative ion generating module. The negative ion generating module according to the present invention can be applied not only to the interior of a vehicle but also to general air cleaners. Further, the negative ion generating module according to the present invention can be applied to many fields of semiconductor manufacturing process, air conditioner, medical space, and industry.

In general, most of the modern people have lived indoors for a long time, and it is important to keep the indoor air clean. As a result, indoor, indoor, The air purifier was installed at any place. Healthy respiratory air is air that does not contain harmful gas components or various odorous substances. It should contain as few volatile organic compounds (VOCs), bacteria, viruses, and new electromagnetic waves as possible. In other words, It is a well known fact that various cation-rich air reduces the quality of life as a cause of various diseases and significantly reduces human comfort, condition maintenance and concentration, as the anion decreases and the cation increases.

Accordingly, a technique for purifying the indoor air has been developed and known. The air purifying technology that has been known up to now removes the dust, dust, and odors in the room and uses a filter or an electrostatic precipitator It is mainstream.

This filter has a disadvantage that it can not effectively maintain the air effectively. In the method using the electrostatic precipitating anion, the anion is generated below the expected value, and ozone oxides which are harmful to the body are generated. In addition, The purification efficiency was not much better than expected.

To solve this problem, a cluster ion generator and a plasma ion generator have recently been proposed and installed in automobiles or other air cleaners.

Among these, cluster ion generators (commonly referred to as "cluster ionizers " in the art) are devices that generate positive and negative ions by high frequency oscillation. Cations and anions are formed by ionizing moisture in the air by high-frequency oscillation and have a form in which a plurality of water molecules are attached around hydrogen ions (H + ) or oxygen ions (O 2- ), that is, in the form of cluster ions . The ions discharged into the air are collected around the suspended particles and cause a chemical reaction with each other, forming hydrogen peroxide (H 2 O 2 ) or hydroxyl radical as an active species, performing an oxidation reaction to remove hydrogen from the suspended particles, Deactivate the suspended particles, and sterilize the suspended bacteria.

The above-described air purification is carried out by the function of ions discharged into the target space and spreading throughout the space, and these ions act on the phase to sterilize the floating bacteria and further cause them to be odorless and harmless So that a satisfactory cleaning effect is obtained over the entire target space. Furthermore, the cluster ions emitted into the space are ions that are present in nature, harmless to the human body, and converted into H 2 O (water) by the oxidation reaction, so that cluster ions are unlikely to cause environmental pollution.

Such an ionizer is usually constructed such that the needle electrode 1 and the flat electrode 2 are spaced apart from each other as shown in Fig. A high-voltage current is applied to the needle electrode 1, and the plate electrode 2 is grounded to generate negative ions.

Here, when a voltage higher than a certain level is applied to the insulator, it acts as a conductor. This phenomenon is called electric breakdown, and electric discharge is caused by the current flowing along with insulation breakdown. When DC voltage is applied between the needle electrode 1 and the flat electrode 2 and the value is gradually increased, the air in the tip portion of the needle electrode 1 causes dielectric breakdown and emits a weak light.

At this time, a current of about 10 A is generated between the electrodes. This discharge is called a corona discharge. In this case, the same local discharge occurs in the liquid or the solid. This discharge is called a partial discharge, Quot; If the voltage is continuously increased, the insulation breakdown occurs at any value between the electrode and the electrode, and the current is increased due to the connection to the discharge path having high conductivity between the electrodes. This is called complete breakdown or flashover, and the interelectrode voltage at which the converter breakdown occurs is called breakdown voltage.

When a corona discharge or a partial discharge occurs in the needle electrode 1, the tip portion of the needle electrode 1 is deteriorated as shown in FIG. 2, so that no further negative ions are generated, It is troublesome to use it.

BRIEF DESCRIPTION OF THE DRAWINGS The invention will be described in more detail with reference to the following illustrative drawings. In describing the present invention, a description of known functions or configurations will be omitted for the sake of clarity of the present invention. In addition, like reference numerals designate like elements throughout the specification.

In one embodiment of the present invention, a dual type high voltage transformer is applied for the sake of explanation. It is designed to discharge negative ions and positive ions, and it is possible to control the frequency of pulses applied to the high voltage transformer to maximize the generation of negative ions and positive ions. The frequency control is performed by a pulse width modulation (PWM) method, and the output voltage of the high voltage transformer is 2000V to 20000V. This is a voltage for increasing the amount of ions. The amount of anion clusters below the output voltage is reduced below the above-mentioned output voltage. However, the amount of clusters of anions is increased above the output voltage but the discharge distance of the ions is not increased. There is a problem of raising the manufacturing cost.

The negative ion generating module applied in the present invention is applied not only to general passenger cars but also to public transportation such as buses and subways. Also, the negative ion generating module applied in the present invention can be applied to all industries such as home and semiconductor manufacturing processes. In a relatively large space other than a general passenger car, not only an anion should be sufficiently generated but also an anion discharge distance should be maintained at a sufficient distance. Therefore, it is preferable that the output voltage of the high voltage transformer applied in the present invention maintains the above voltage range.

Hereinafter, an anion generating module according to one embodiment of the present invention will be described with reference to FIG. 3 and FIG. 4 as necessary.

FIG. 3 illustrates an anion generating module circuit according to one preferred embodiment of the present invention. The circuit includes a dual high-voltage transformer 211 wound with a coil and having a dual structure for ensuring a set voltage output, A positive output circuit 213 connected to the output terminal of the dual high voltage transformer 211 to supply a high voltage to the discharge pin 215 for discharging the negative ion and the positive ion respectively; A power supply section 209 for supplying a bias voltage to the oscillation circuits 207 and 205 and an oscillation circuit 207 for switching the oscillation circuits 207 and 205 And a pulse control unit 203 for supplying a pulse signal for control.

The discharge pin 215 is connected to a ground terminal of the dual high voltage transformer 211. The discharge pin 215 is connected to the earth terminal of the dual high voltage transformer 211, And a discharge pin provided so as to face the + discharge pin at the center. Therefore, positive clusters are generated between the positive discharge pin and the ground discharge pin, and anions are generated between the negative discharge pin and the ground discharge pin. Here, the discharge fin means a needle-shaped electrode having a pointed peak.

The power supply unit 209 uses 9V, 12V, 24V, or 36V as a bias voltage for switching, and is switched from 48 Hz to 52 Hz by each oscillation circuit. When the power source unit itself is an alternating current source, it is applied after the voltage is converted into the voltage range by a separate transformer. In the case of a direct current source, the power source unit is switched to alternating current by a separate inverter as shown in FIG. .

The switching signal is provided to the input terminal of the dual high-voltage transformer 211, and is output at a high voltage according to the number of coils wound. The dual high voltage transformer 211 outputs a high voltage according to the number of windings of the secondary coil relative to the primary coil. The output voltage of the dual high voltage transformer 211 proposed in the present invention is 2000V to 20000V.

The anode output circuit 213 is connected to the output terminal of the dual high voltage transformer 211. The anode output circuit 213 selects the polarity of the voltage based on the direction of the diode, .

Accordingly, the high voltage supplied through the positive output circuit 213 is provided to the discharge pin 215, and the discharge pin 215 includes a (+) discharge pin and a (-) discharge pin, And a ground discharge pin.

The structure of the discharge pin 215 is for stably discharging a high voltage. The diameter of a terminal end of the (+) discharge pin and the (-) discharge pin proposed in the present invention is set to be 8 μm to 10 μm, Structure.

The diameter of the end portion of the earth discharge fin is set to be 180 mu m to 200 mu m. The structure of the discharge pin 215 increases the emission distance of negative ions. When the terminal diameter of the (+) discharge pin and the (-) discharge fin exceeds 10 μm, the ion emission distance is reduced.

That is, in the present invention, a needle-shaped electrode (discharge pin) having a sharp tip is used as the + electrode and the - electrode. Since the needle-shaped electrodes are used in both the positive electrode and the negative electrode, the positive electrode serves as the negative electrode and the negative electrode serves as the positive electrode depending on the voltage alternately applied at a constant frequency. Thus, corona discharge, which may occur in the electrode, So that the deterioration phenomenon does not occur in the electrode portion of the needle bed.

In addition, one preferred exemplary operating condition of the present invention is shown in Table 1 below.

value Input voltage 12V Maximum Input Voltage 36V Minimum Input Voltage 9V Input current 0.1A Output voltage 2000 to 20000V Output current 300uA Switching frequency 50 kHz efficiency 90% Regulation 0.15 Maximum magnetic flux density 0.15 T Window utilization 0.3 Duty cycle 0.5 Maximum temperature rise 70 ℃

FIG. 1 shows experimental results under the conditions according to the present invention and conventional experimental results. In the present invention and other conventional conditions, the electrodes are alternately applied in the case of the present invention.

As can be seen from FIG. 1, it can be confirmed that no deterioration phenomenon occurs in the case of the needle-shaped electrode.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined in the following claims. It can be understood that it is possible.
