Description

[0001] The present invention relates to an air purification sterilizer using a static electricity,

More particularly, the present invention relates to an air purification sterilizer using static electricity, and more particularly, to an air purification sterilizer that maximizes efficiency of air purification through sterilization using high voltage static electricity, increases the efficiency of generation of high voltage by specifying a surface material of a static electricity generating portion that generates static electricity To an air cleaning sterilizer using static electricity so that foreign matter is not adsorbed on the surface of the static electricity generating portion.

Generally, there are various kinds of bacteria in the air, and people are inhaling these bacteria in their daily life without any filtration, which is harmful to health.

In particular, contaminated air can have a very bad effect on the health of the elderly and infants. Therefore, it is recommended to avoid going out when the pollution degree of outside air is bad.

However, it is not easy to provide a satisfactory environment in the indoor air condition.

In the case of households, it is necessary to ventilate with outside air due to the harmful gas generated when food is cooked. In other industrial sites or public places, it is also difficult to provide environment that is always satisfactory compared with the outside air.

Various types of air purifying devices have been proposed to solve such indoor air defects, and they are widely used in real life.

In the conventional general air purifier, the air is purified using a dust filter using a non-woven fabric or the like and an activated carbon filter for removing odors to remove dust contained in the air.

However, although the above air purifier has some effect for removing dust contained in the air, it does not have a function to sterilize the bacteria contained in the air, so that it is not effective to reduce air pollution.

Particularly, as air pollution becomes serious recently, indoor air contains various kinds of organic substances which cause odor including pathogenic bacteria such as various viruses, E. coli or mold.

In recent years, an air sterilizer capable of sterilizing contaminated air and converting it into clean air has been known as "Korean Registration No. 20-0337042" &Quot;

However, the conventional air sterilizer also has a disadvantage in that sterilization treatment is limited due to sterilization of air by ultraviolet rays irradiated from ultraviolet lamps, and a large amount of ozone (O3) is generated and harmful to human body.

It is difficult to treat various kinds of organic substances which cause smell contained in the air, and thus, there is a problem that they are discharged to the outside as they are.

It is to be understood that the words or words used in the present specification and claims are not to be construed in a conventional or dictionary sense and that the inventor can properly define the concept of a term in order to describe its invention in the best possible way And should be construed in light of the meanings and concepts consistent with the technical idea of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an air purifier using static electricity according to a preferred embodiment of the present invention will be described with reference to FIGS.

The air purification sterilizer (hereinafter referred to as "air purification sterilizer") using static electricity has a technical feature of eliminating toxic and odorous factors by eradicating various bacteria contained in the outside air by generating a high voltage static electricity, have.

In addition, there is a technical feature in which the surface material of the static electricity generating part for generating static electricity is specified to maximize the efficiency of the formation of the electrostatic voltage and the foreign matter or dust inside the air cleaning sterilizer is prevented from being adsorbed to the static electricity generating part.

Thus, substantial air purification can be performed on the room air, and the function of the static electricity generator can be prevented from being deteriorated.

1 and 2, the air purifier includes a body 100, a power source unit 200, an electrostatic generator 300, an adjusting unit 400, and a suction unit 500 .

The body 100 constitutes the exterior of the air purifier and protects the components.

The shape of the body 100 is not limited and may be variously provided in consideration of aesthetics.

For convenience of explanation, in the present specification, it is assumed that the body 100 is made of a rectangular parallelepiped.

The body 100 has a front surface formed with an intake hole 110 through which outside air is sucked.

The body 100 is made of an insulating material and the dial 120, the switch 130 and the LED 140 are installed on one side and the other side of the body 100.

The dial 120 controls the controller 400 for controlling the size of the power source inside the body 100, and is configured as a rotary type.

That is, the dial 120 is provided so as to be rotatable in either the left or right direction, and is installed so as not to be rotated any more after being rotated by a specified range in one direction.

Although not shown, restraining means are provided inside the body 100 corresponding to both sides of the dial 120.

The dial 120 is configured such that when the dial 120 is turned to the left or to the right, the size of the power supply 200 can be adjusted through the adjusting unit 400 described later. .

The switch 130 functions to turn on / off the power source 200 through a circuit unit described later, and is preferably configured in a two-contact manner.

The switch 130 serves to switch modes while sliding in the upward and downward directions as shown in FIG.

That is, when the upper end of the switch 130 is referred to as one contact and the lower end of the switch 130 is referred to as two contacts, static electricity is generated through power application of the power source 200 through the circuit portion at one contact, The power is cut off.

The LED 140 serves to indicate the operation state of the air purifier.

For example, in the mode in which static electricity is generated from the static electricity generator 300 and the bacteria and viruses can be sterilized, the green lamp is turned on, and when the voltage of the static electricity becomes excessively high for a long period of time, .

Meanwhile, a cradle 150 for mounting the body 100 is provided.

The cradle 150 supports the body 100 and is connected to an external power source to supply or charge power to the power source 200 of the body 100.

To this end, although not shown, a charging terminal is installed in the cradle 150 and the body 100, respectively.

The AC / DC converter is built in the platform 150, and converts commercial AC power to DC power to supply power to the power supply 200.

The cradle 150 includes a plurality of legs 152 for supporting the body 100 in a state where the body 100 can be stably mounted.

It is preferable that a plurality of LEDs are provided on the upper end of the holder 150 so as to be able to grasp the state of charge of the power source 200.

For example, the red state is turned on in the state of charge state, the green state is in the state where charging is completed, and the purple state is blinking in the state where charging is not performed due to the defective contact terminal.

Next, the power supply unit 200 functions to apply power to the respective components, and is installed inside the body 100.

The power source unit 200 is provided to be charged through an external power source and may be embedded in the body 100 or may be detachably attached to the lower portion of the body 100.

That is, as shown in FIG. 2, the power supply unit 200 may be provided with a battery type that can be charged and replaced.

The power supply unit 200 is connected to the circuit unit 210 via the switch 130, as shown in FIG.

The circuit unit 210 receives power from the power supply unit 200 and supplies power to the suction unit 500 and the control unit 400 according to the operation of the switch 130 as described above.

At this time, the circuit unit 210 converts the applied power to a high voltage by using a DC-DC converter and outputs it.

Next, the static electricity generating part 300 receives the potential generated from the adjusting part 400 through the electrode to generate static electricity to eradicate and disassemble the bacteria and odor substances.

The static electricity generating unit 300 generates a high voltage of 12,000 V (current 1 mA) to kill and decompose bacteria and odorous substances.

That is, bacteria and viruses are decomposed into cell membranes due to a high high voltage (12,000 V or more) instantaneously applied from the static electricity generating unit 300, causing genetic damage and rapidly killing, and various harmful and odorous substances are exposed to high voltage The molecular chain is broken down into a form in which the harmful and odorous factors disappear.

Since the voltage generated from the static electricity generating unit 300 is as high as 12,000 V or more but the current is as low as 1 mA, there is no need to worry about the risk of a safety accident even if it is exposed to a human body, and the static electricity generating unit 300 is provided inside the body 100 Since there is no risk of being exposed to the human body, safety accidents do not occur.

Even if the person disassembles the body 100 and contacts the static electricity generator 300, the voltage is high as described above, but the amount of current is very low, about 1 mA, so that there is no need to worry about the risk of a safety accident.

Meanwhile, the static electricity generator 300 is installed inside the body 100 as described above, and at least one static electricity generator 300 is installed.

The static electricity generator 300 may be installed on both sides of the body 100.

On the other hand, the surface material of the static electricity generator 300 is made of polyethylene (PE). The surface of the static electricity generator 300 made of polyethylene hardly increases the voltage of the static electricity due to the material characteristics.

It is necessary to induce the electrostatic voltage to be high since a high voltage is applied to kill and decompose the bacteria and odor materials.

Accordingly, even if the surface material of the static electricity generator 300 is made of polyethylene, the present invention has a technical feature of increasing the antimicrobial effect by inducing high voltage static electricity.

For this, the surface material of the static electricity generating part is preferably mixed with the constituent materials shown in Table 1 below.

Constituent material The Composition ratio Magnesium carbonate MgCO3 18 wt% to 22 wt% Zinc carbonate ZnCO3 18 wt% to 22 wt% Tartaric acid C4H6O6 29 wt% to 31 wt% Oxalic acid C2H2O4  8 wt% to 12 wt% Selenium dioxide SeO2  4% to 6% Galvin Allanite 14 wt% to 16 wt%

When the material of Table 1 is mixed with polyethylene which is the surface material of the static electricity generating part 300, it is possible to form a high electrostatic voltage and to prevent the charge transfer inside the polyethylene, It is possible to prevent fine dust or foreign matter from being adsorbed on the static electricity generating part 300.

That is, when the charge movement within the polyethylene easily occurs, fine dust and foreign matter continue to be adsorbed on the surface of the static electricity generating part 300 and accumulate. This acts as an obstacle to the application of high voltage static electricity, The surface of the electrostatic generator 300 is manufactured by mixing the material of Table 1 with polyethylene constituting the surface of the electrostatic generator 300 so that the electrostatic induction of high voltage is easily performed At the same time, the charge transfer inside the polyethylene is disturbed, so that the problem of fine dust and foreign matter adsorbing on the surface of the static electricity generating part 300 can be prevented in advance.

The compositional ratio of the above materials is measured by a standard energy measuring device and it is found that the most orbital (HOMO) having the highest energy among the molecular orbitals containing electrons and the molecular orbital containing no electrons The difference between the low orbital (LUMO) and the lowest unoccupied molecular orbital (LUMO) was calculated to calculate the optimum mixing ratio of the constituent materials.

Precisely, 5% by weight of the mixed composition composed of the experimental ratio shown in the following Table 2 was put into the PE material to prepare a plastic hexahedron of 100 X 100 X 10 (mm), and then, the HOMO-LUMO energy difference measurement value The composition ratios of the constituent materials in which the internal charge transfer is least active are calculated and presented at an optimum ratio.

Constituent material The Composition ratio 1 Composition ratio 2 Composition ratio 3 Composition ratio 4 Magnesium carbonate MgCO3 20 wt% 20 wt% 20 wt% 20 wt% Zinc carbonate ZnCO3 20 wt% 20 wt% 20 wt% 20 wt% Tartaric acid C4H6O6 30 wt% 35 wt% 30 wt% 30 wt% Oxalic acid C2H2O4 10 wt% 0 wt% 5 wt% 5 wt% Selenium dioxide SeO2 5 wt% 5 wt% 15 wt% 20 wt% Galvin Allanite 15 wt% 10 wt% 10 wt% 5 wt% 8 species in total 100 wt% 100 wt% 100 wt% 100 wt% HOMO-LUMO energy difference
(Unit: eV) 1.2 3.5 2.7 2.2

As can be seen from this, in the case of the composition ratio 1, the energy gap between the HOMO-LUMO is the smallest, so that the charge transfer within the sample is not active at all.

Thus, the composition ratios of Table 1 for preventing the charge movement inside the polyethylene as the surface material of the static electricity generating portion can be presented.

Next, the controller 400 controls the size of the power source when the boosted voltage is applied to the circuit unit 210.

The control unit 400 includes a positive potential generating unit 410 and a negative potential generating unit 420.

The positive and negative potentials generated in the positive potential generating portion 410 and the negative potential generating portion 420 are changed in polarity according to the operation of the dial 120 provided in the body 100 and the magnitude of the generated potential is adjusted .

Preferably, when the dial 120 is turned to the left, the negative potential is generated, and the negative potential is increased according to the turning degree. When the dial 120 is turned to the right, the magnitude of the positive potential It is preferable to be interlocked with the dial 120 so as to be larger.

The suction unit 500 serves to guide the outside air into the body 100 and guide the air to the static electricity generator 300 and is installed in the air intake hole 110 formed in the body 100.

The suction unit 500 includes a suction fan 510 and a filter cartridge 520 as shown in FIG.

The suction fan 510 is installed to correspond to the suction hole 110, and is installed so as to be rotatable by a driving unit such as a motor (not shown).

At this time, it is natural that the blade direction of the suction fan 510 should be a direction in which the outside air can be sucked.

The filter cartridge 520 filters the dust and foreign substances contained in the outside air in the process of sucking the outside air into the inside of the body 100 through the suction of the suction fan 510.

That is, when foreign substances contained in the outside air are directly introduced into the body 100 by the suction fan 510 without filtration, the functions of the parts may be deteriorated. Particularly, when foreign substances are adsorbed on the static electricity generating part 300 The filter cartridge 520 is provided in front of the suction fan 510 because the function of the static electricity generator 300 is deteriorated and it may be difficult to perform the function as the air purifier.

The filter cartridge 520 includes a frame 521 constituting a frame of the filter and a paper filter 522 constituting a portion corresponding to the suction fan 510.

The filter cartridge 520 may be detachably attached to the body 100.

At this time, the filter cartridge 520 is detachably attached to the body 100 through bolt assembly.

This is so that the filter cartridge 520 can be replaced at regular intervals, so that the air cleaning sterilizer can be maintained hygienically.

At this time, since the filter cartridge 520 is substantially constituted by the paper filter 522, it is possible to reduce the burden on the replacement cost, thereby reducing the maintenance cost.

Hereinafter, the operation of the air purifier using the static electricity having the above-described configuration will be described.

When the switch 130 is slid and positioned at one contact, the circuit unit 210 receives power from the power supply unit 200 and converts the applied power to a high voltage by using a DC-DC converter.

Thereafter, the voltage boosted by the circuit unit 210 is applied to the control unit 400 and the suction unit 500, and the control unit 400 adjusts the size of the power source.

That is, the polarity of the positive and negative potentials generated in the positive potential generating portion 410 and the negative potential generating portion 420 through the user's dial operation is changed, and the magnitude of the potential is adjusted.

As the power is applied, the suction fan 510 of the suction unit 500 is rotated to suck the outside air into the body 100.

At this time, dust and foreign matter are filtered through the paper filter 522 and then introduced into the body 100.

The positive and negative potentials generated in the electrostatic generator 400 are received by the electrostatic generator 400 through the suction unit 500. The positive and negative potentials generated by the electrostatic generator 400 are received through the suction unit 500, Bacteria, viruses, harmful substances and odorous substances contained in the outside air are killed and decomposed.

Thus, indoor air can be maintained comfortably.

Meanwhile, in the preferred embodiment, since the detachment of the filter cartridge is performed through the bolt assembly, the replacing operation can be troublesome, and the filter cartridge can be easily detached and attached through another embodiment.

Prior to description, the same reference numerals are given to the same components as those of the preferred embodiment, and a detailed description thereof will be omitted.

The detachment means 600 for easily replacing the filter cartridge 520 includes a guide piece 610, an elastic member 620 and a stopper 630. [

As shown in FIG. 4, the guide piece 610 is configured to form a slide groove 611 having one side opened, and is installed in the body 100 corresponding to the periphery of the suction fan 510.

The guide piece 610 includes a bent portion 612 bent outward from the body 100 and the length of the bent portion 612 corresponds to the frame 521 of the filter cartridge 520. [

The elastic member 620 serves to closely adhere the filter cartridge 520 to the body 100.

So that airtightness is maintained between the body 100 and the frame 521 of the filter cartridge 520 when the filter cartridge 520 is coupled to the guide member 610.

The elastic member 620 is fixed along the back surface of the bent portion 612 of the guide piece 610.

The slide groove 611 is formed between the elastic member 620 and the body 100 and the interval between the slide grooves 611 is formed to be smaller than the thickness of the frame 521 of the filter cartridge 520. [

The stopper 630 serves to prevent the filter cartridge 520 inserted through one side of the guide piece 610 from being released through the opened portion and is installed in the body 100.

The stopper 630 interferes with one side of the filter cartridge 520 inserted into the slide groove 611. When the filter cartridge 520 is inserted into the slide groove 611, 520 are not interfered with each other.

For this, the stopper 630 is formed of a ball elastically supported inside the body 100 so as to be able to move in and out of the body 100.

At this time, the body 100 is pushed by the elastic force of the spring 630 to form a through hole having a size such that only a part of the ball is exposed.

The detachment of the filter cartridge 520 by the detachment means having the above-described structure will now be briefly described.

The filter cartridge 520 is inserted into the slide groove 611 of the guide piece 610 having one side opened.

At this time, the ball 631 of the stopper 630 is drawn into the inside of the body 100 by the front end portion of the filter cartridge 520 and is supported by the contracted spring 632.

The filter cartridge 520 is inserted into the slide groove 611 and the elastic member 620 is contracted with an elastic force to secure the space of the slide groove 611 into which the filter cartridge 520 can be inserted.

When the insertion of the filter cartridge 520 into the slide groove 611 is completed, the elastic member 620 brings the frame 521 of the filter cartridge 520 into close contact with the body 100 with a restoring force.

As shown in FIG. 5, the ball 631, which has been drawn into the body 100, protrudes through the through hole due to the restoring force of the spring 632, interfering with the end of the filter cartridge 520.

Thus, the installation of the filter cartridge 520 is completed.

On the other hand, in order to replace the filter cartridge 520, the elastic member 620 and the spring 632 of the stopper 630 contract as the filter cartridge 520 is arbitrarily pulled from the slide groove 611, The separator 520 can be smoothly separated.

As described above, the air cleaning sterilizer using the static electricity according to the present invention has a technical feature to kill and isolate bacteria, viruses and odor substances contained in the indoor air by using high voltage static electricity.

Accordingly, not the simple air purification through dust and foreign matter trapping, but the air pollution origin can be eradicated so that the actual air purification can be performed.

In addition, since the surface material of the static electricity generating portion for generating static electricity is specified and manufactured, not only the efficiency of high voltage generation can be enhanced, but also the foreign matter or dust can be prevented from being adsorbed on the surface of the static electricity generating portion, .

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art.
