Description

Ionic wind air purifier {IONIC WIND TYPE AIR CLEANER}

The present invention relates to an ion wind air purifier, and more particularly, to an ion wind air purifier, which collects particles charged by corona discharge and is easy to maintain through easy installation/detachment of a configuration in which particles are collected, while promoting user safety.

Fine dust is an immediate problem that threatens public health. Public awareness of fine dust is becoming more serious as time goes by, and government-wide efforts are being made to reduce fine dust.

On the other hand, about 7% of the fine dust in the air in Seoul is emitted from grilled restaurants, such as grilled meat or fish, and the concentration of ultrafine dust soars to 13 times (1013㎍/㎥) of the 'very bad' standard. and the health of guests, but at present, government-level measures are far off.

The electrostatic precipitator, which removes fine dust contained in the air flow of about 1 m/s generated by the blower using corona discharge, can be an effective countermeasure to civil complaints around the business surrounding fine dust and odor pollution emitted by grilled restaurants. .

However, since the configuration in which fine dust is collected is a consumable product due to the collected fine dust on the surface, periodic cleaning or replacement is required. However, in the case of most ion wind air purifiers, it is difficult to replace such a configuration, and it is solved by additionally introducing a wet cleaning configuration. However, this increases the cost and is pointed out as a problem that is difficult to use at home.

In addition, when corona discharge is used, there is a critical problem of generating ozone harmful to the human body. As the applied current increases, the collection efficiency increases, but the ozone concentration also increases, making it difficult to use indoors.

Therefore, it is necessary to develop an ion wind air purifier in which the ozone concentration does not increase when used indoors while it is convenient to replace the configuration for collecting fine dust.

It is a front view of the ion wind air purifier according to the embodiment.

An ion wind air purifier according to an embodiment of the present invention includes an emitter 100, a collector module 200, a non-collecting unit 300, a case 400, and a grill 500.

In the ion wind air purifier 1000, the emitter 100, the collector module 200, and the non-collecting unit 300 can be arranged in various ways, but in this embodiment, the emitter 100 includes the collector module 200 and the non-collecting unit (300) It explains that it arranges below.

In this embodiment, the emitter 100 may be formed of a thin wire. Or, in another embodiment, it may be provided in a sawtooth shape by processing a thin metal plate. A high voltage is applied between the emitter 100 and the collector 210. When the voltage of the emitter 100 is high relative to the collector 210, it is positively discharged (+discharged), and when the voltage of the emitter 100 is low, it is negative. discharge (-discharge). In this case, the application of the high voltage may be supplied through a high voltage power source (not shown).

Meanwhile, in this embodiment, the emitter 100 uses a tungsten wire having a diameter of 0.05 mm, but is not necessarily limited thereto.

The collector module 200 is disposed above the emitter 100, and a plurality of collectors 210 are spaced apart from each other. The plurality of collectors 210 are connected to each other through a connecting member (not shown). This will be described later.

4 is a particle collection explanatory diagram of an ion wind air purifier according to an embodiment of the present invention.

When a high voltage is supplied to the emitter 100, a high-intensity electric field is formed near the surface of the emitter 100, and when the intensity of this electric field exceeds a specific value, cations and anions coexist around the emitter 100 A plasma region is formed. In this region, electrons are accelerated at a high speed and collide with air molecules, causing an ionization phenomenon in which air molecules are separated into positive ions and electrons. This process is also called electron avalanche because it generates a large amount of electrons and positive ions in an instant.

The movement of these cations is caused by the Coulomb force of the ions in the space between the emitter 100 and the collector 210.

Since the emitter 100 is disposed below the collector 210, the ion wind forms an upward air current. Positive ions moving from the emitter 100 to the collector 210 collide with and attach to particles in the air, thereby charging the particles with a positive (+) charge. When air moves to the collector 210 side, which is the outlet side, due to the collision of ions and neutral molecules, a negative pressure is formed in this space, so that external air is introduced again from the inlet side, the emitter 100 side, and a constant flow rate is generated.

The non-collecting unit 300 is configured to collect charged particles in the collector 210 . A plurality of non-collecting units 300 are provided and disposed alternately (alternatively) with the collectors 210 . A high voltage is applied to the non-collecting unit 300 to collect positively charged particles in the collector 210 .

That is, in this embodiment, the collector 210 is configured to charge particles through corona discharge and generate ion wind in relation to the emitter 100, and to collect charged particles in relation to the non-collecting unit 300 do

In other words, in this embodiment, the collector 210 and the collection electrode have an integrated structure.

In this embodiment, the length of the collector 210 is formed longer than the length of the non-collecting part 300 . Of the collector 210, a region corresponding to the emitter 100 functions as a collector, and a region corresponding to the non-collecting portion 300 functions as a collecting electrode. At this time, the end of the collector 210 protrudes toward the emitter 100 compared to the end of the non-collecting part 300 . Here, protruding means that the end of the collector 210 is closer to the emitter 100 than the end of the non-collecting part 300 (see FIG. 4). By protruding toward the emitter 100 compared to the end, the electric field around the emitter 100 becomes stronger.

The case 400 includes a pair of sidewalls 410 spaced apart from each other, an emitter mounting portion 600, and a fixing portion 700. The fixing part 700 is a configuration in which the collector module 200 and the non-collecting part 300 are mounted. The fixing part 700 includes a collector fixing part 800 and a non-collecting part fixing part 900 .

The emitter mount 600 is mounted on the sidewall 410 . In this embodiment, both ends of the emitter mounting portion 600 are mounted on the inner surfaces of the pair of sidewalls 410, but there may be various examples of coupling and is not limited to any one coupling method.

Meanwhile, in this embodiment, since the emitter 100 is disposed below the collector 200, the emitter mounting portion 600 is mounted below the sidewall 410.

The emitter mounting portion 600 may be mounted through which the emitter 100 passes, or a mounting groove may be formed to place the emitter 100 therein.

The collector fixing part 800 is disposed above the emitter mounting part 600 . A plurality of grooves 810 are spaced apart from each other in the collector fixing part 800 , and the lower end of each collector 200 is inserted into each groove 810 .

In this embodiment, a separation space A is formed between the emitter mounting portion 600 and the collector fixing portion 800 . The separation space (A) is formed between the mounting groove in which the emitter 100 is mounted and the groove portion 810 . The separation space (A) is formed to prevent insulation breakdown. If there is no separation space (A), insulation breakdown can occur even at a very low voltage (2 to 3 kV). That is, creepage discharge may occur from the emitter 100 to the collector 200 at a low voltage, and when the surface is contaminated, the breakdown voltage is further lowered. Therefore, creepage discharge is prevented by forming the separation space (A).

The emitter mounting portion 600 and the collector fixing portion 800 are separated and may be fixed to the sidewall 410 to form a separation space A.

Assuming that the distance between the emitter 100 and the collector 200 is the electrode spacing, the current changes approximately in inverse proportion to the cube of the electrode spacing when the applied voltage is constant. Therefore, a fatal problem arises in that even a small change in the electrode spacing causes a large change in current. However, in this embodiment, the separation space between the emitter mounting part 600 and the collector fixing part 800 is kept constant, so that the distance between the emitter 100 and the collector 200 can be kept constant.

Alternatively, the emitter mounting portion 600 and the collector fixing portion 800 may be integrally formed. That is, the emitter mounting portion 600 and the collector fixing portion 800 may be integrally connected to each other, but a separation space A may be formed. In this case, both ends of the emitter mounting portion 600 and the collector fixing portion 800 may be provided integrally with each other, and a separation space A may be formed therebetween. Since the emitter mounting portion 600 and the collector fixing portion 800 are integrally formed, a distance between the emitter 100 and the collector 200 is maintained constant.

The non-collecting part fixing part 900 is formed on the upper surface of the collector fixing part 800 . The non-collecting part fixing part 900 is also provided in plurality, and is formed between the respective groove parts 810 .

The non-collecting part fixing part 900 has a substantially plate shape long in the height direction, and has a through hole 910 formed therein. Fitting grooves 920 are formed above and below the through hole 910, and the upper and lower ends of the non-collecting part 300 are respectively inserted.

In this embodiment, the width of the through hole 910 is formed wider than the width of the non-collecting portion 300. This is to prevent the aforementioned creeping discharge. The width of the through hole 910 is formed wider than the width of the non-collecting portion 300 to form an air insulation space on both sides of the non-collecting portion 300, thereby maximizing the air insulation thickness and preventing creepage discharge.

In addition, since the non-collecting part fixing parts 900 are spaced apart from each other, a space 940 is formed between the non-collecting part fixing parts 900, and the collector 210 is disposed in this space. The interval is wider than the width of the collector 210 . In other words, the width of the non-collecting part fixing part 900 is smaller than the interval between the groove parts 810 . That is, air insulation spaces are formed on both sides of the collector 200 . Similar to the air insulation space on both sides of the non-collecting unit 300, air insulation spaces are formed on both sides of the collector 200 to maximize the air insulation thickness and prevent creepage discharge.

Meanwhile, a protrusion 930 protruding from the side is formed on the top of the non-collecting part fixing part 900 . The protrusion 930 serves as a guide so that the collector 200 can be easily mounted when inserted.

A guide groove, which is a space between the protruding parts 930 of the neighboring non-collecting part fixing parts 900, is formed, and the collector 200 is inserted/removed through the guide groove, so that attachment and detachment is easy.

At this time, both side surfaces of the collector 200 may come into contact with the protruding portion 930 . That is, the lower end of the collector 200 is inserted into the groove 810 and fixed, and both sides of the upper end may come into contact with the protruding part 930 .

7 is a perspective view of a grill of an ion wind air purifier according to an embodiment of the present invention, FIG. 8 is an enlarged view of a main part of a grill of an ion wind air purifier according to an embodiment of the present invention, and FIG. It is an explanatory diagram of the assembly of the grill of the ion wind air purifier according to an embodiment.

The grill 500 is configured to prevent a user's hand from being put into the air purifier, particularly to a component to which a high voltage is applied. The grill 500 is disposed below the emitter 100 .

The grill 500 includes a plurality of short parts 510 and a plurality of long parts 520 . The grill 500 is manufactured by assembling a plurality of short parts 510 and long parts 520 in a lattice form.

When the grill 500 is disposed under the emitter 100 for safe use, the grill 500 may have a great effect on the outlet wind speed, that is, the amount of air purification, due to a difference in fluid drag according to the structure of the grill 500. Therefore, a structure of the grill 500 that minimizes fluid drag is required, and the fluid drag decreases as the opening degree (flow passage area/total area) increases.

Accordingly, in this embodiment, the short part 510 and the long part 520 made of a PVC film having a thickness of 0.3 mm are assembled in a lattice form by fitting each other. That is, the grill 500 is not manufactured through adhesion, but through fitting through a structural form, so that the effect on the fluid drag is very small.

The short part 510 is provided in a substantially rectangular shape, and a first cutout 511 and a second cutout 512 are formed. The first cutout 511 is formed by cutting inward from one side surface, and the second cutout 512 is formed by cutting inward from the other side surface. The first cutout 511 and the second cutout 512 are parallel to the width direction of the piece part 510 . The first cutout 511 is formed at a position corresponding to the second cutout 512 , that is, the first cutout 511 and the second cutout 512 are formed on the same virtual line. The sum of the lengths of the first cutout 511 and the second cutout 512 is shorter than the width of the short part 510 . Accordingly, a non-cutting portion 513 is formed between the first cutout 511 and the second cutout 512 .

Meanwhile, for easy assembly with the long part 520, the first cutout 511 and the second cutout 512 may be chamfered.

The long part 520 is provided in a substantially rectangular shape and has a third cutout 521 formed therein. The third cutout 521 includes an inclined cutout 522 and a fitting cutout 523 . The inclined cutout 522 is formed by incising the long part 520 inwardly while forming an inclination from one side surface. The fitting cutout 523 is formed parallel to the width direction of the long part 520 . One end of the fitting cutout 523 extends from the long part 520 and communicates with each other. At this time, a locking jaw 524 is formed on the top of the fitting cutout 523. That is, the fitting cutout 523 is formed inside the long part 520 and is not formed from one end.

On the other hand, the long part 520 and the short part 510 cross each other perpendicularly by the third cutout 521 and the second cutout 512, and the locking jaw 524 is the first cutout 511. Since the long part 520 and the short part 510 are coupled to each other by being inserted into, the length of the fitting cutout 523 corresponds to the length of the non-cutting portion 513 and the locking jaw 524 is the first cutout. Corresponds to the length of (511).

10 is a longitudinal cross-sectional view of a collector of an ion wind air purifier according to an embodiment of the present invention.

The collector 210 and the non-collecting unit 300 may have a lightweight structure.

In this case, the collector 210 has a structure in which the first conductive member 230 is covered with a light first foam 220 .

Since it is difficult to form a structure when only the thin first conductive member 230 is used to reduce the weight of the collector 210, in this embodiment, the first foam 220 having a low density is covered with the first conductive member 230 As a result, it is very light and easy to form a structure, and functions as an electrode through which current flows by the first conductive member 230 (see (a) in FIG. 10).

In the collector 210 , the first form 220 is covered with the first conductive member 230 . The first conductive member 230 may form a round 240 from one end of the first form 220 . Here, the round 240 means a protruding shape located at one end of the first form 220 . More preferably, the round 240 means a semicircular cross section having a radius R (see FIG. 10(b)).

The first foam is any one of expanded polystyrene (EPS: expanded polystyrene or Styrofoam), expanded polypropylene (EPP: expanded polyprop), expanded polyolefin (EPO: expanded polyolefin), Woodrock, and Deprone (closed cell polystyrene). can be one

When the round 240 is formed in the collector 210, the reverse discharge phenomenon can be minimized and dust particle collection performance can be maximized. Also, since the round 240 is formed, generation of sparks can be minimized. Here, the reverse discharge phenomenon means a phenomenon in which negative ions travel from the collector 210 toward the emitter 100 as the voltage increases. Reverse discharge may occur when the electric field exceeds a certain level. Since the strength of the electric field on the surface of the round 240 is inversely proportional to R, it is desirable to maximize R if possible so that this voltage does not occur.

Alternatively, the collector may be made of an aluminum plate (or thin SUS plate).

The plurality of collectors 210 may be connected through a connecting member (for example, an alligator clip).

11 is an explanatory view of a non-collecting part of an ion wind air purifier according to an embodiment of the present invention, and FIG. 12 is an explanatory view of the connection relationship between non-collecting parts of the ion wind air purifier according to an embodiment of the present invention.

The non-collecting unit 300 has a structure in which an electrode is covered with a PVC film 320. Specifically, in the non-collecting unit 300, the electrode is provided as the second conductive member 310, and has a structure in which the PVC film 320 is covered on the second conductive member 310. Here, "covered" includes not only the PVC film 320 covering the second conductive member, but also the PVC film 320 provided to have an input space so that the second conductive member is accommodated inside the PVC film 320.

Also, the first conductive member 230 and the second conductive member 310 may be a conductive film or an aluminum foil. In the case of using a conductive film, aluminum may be deposited on a PET film.

In this embodiment, unlike the collector 210, the non-collecting unit 300 is not lightweight by using a foam material. This is to minimize the influence of the ion wind due to the thickness of the foam.

By having a structure in which the PVC film 320 is covered on the second conductive member 310, sparks that may occur at the electrodes are prevented, thereby increasing the dielectric breakdown voltage. When a voltage is applied to the electrode, a spark may be generated at a low voltage. The higher the voltage and the greater the strength of the electric field, the higher the efficiency of collecting fine dust, but there is a problem in that sparks are generated when voltage is applied. In particular, at the end of the metal, leakage current may occur even below the dielectric breakdown voltage, resulting in high energy consumption. In this embodiment, the second conductive member is accommodated in the PVC film 320 having an input space, so that sparks It is prevented and the insulation breakdown voltage is maximized, so the collection efficiency of fine dust is excellent.

Particles are collected in the collector 210 by a voltage difference applied to the emitter 100 and the collector 210 . That is, since the emitter 100 is an anode and the collector 210 is a cathode, positively charged particles are collected in the collector 210 during corona discharge. In addition, particles are collected in the collector 210 by a voltage difference applied to the electrode (second conductive member 310) of the non-collecting unit 300 and the collector 210 . Particles are collected at the end of the collector 210 facing the emitter 100 due to a voltage difference applied between the emitter 100 and the collector 210, but the particle collection amount may be insufficient only with this mechanism. Therefore, if the electrode of the non-collecting part 300 is the same anode as the emitter 100, most of the particles are collected on the surface of the collector 210, which is a cathode facing the non-collecting part 300. The particle collection amount by this mechanism is much greater than the particle collection amount at the end of the collector 210, and the collection efficiency of ultra-fine particles increases as the area of the collector 210 increases.

Electrodes of the plurality of non-collecting parts 300 may be connected to each other through lead wires 340 . In order to improve insulation performance, the lead wire 340 may also have an insulating structure, and in this case, the lead wire 340 may be disposed inside the double insulation tube 350. Here, the double insulation tube 350 may be a heat shrink tube or a silicon tube. The double insulation tube 350 and the insulating member 330 may be bonded to each other through high-frequency bonding or ultrasonic bonding. Sparks with the sharp end of the collector 210 can be prevented by using the double insulation tube 350 .

The case 400 has a structure in which the top and bottom are open. The lower part is a passage through which air is introduced through corona discharge, and the upper part is a passage through which ion wind is discharged. The case 400 has a structure in which the top and bottom are open, and the lower end of the collector 210 is inserted into the groove 810 and both sides of the upper end are guided to the protrusion 930, so the collector 210 has a top and bottom detachable structure. have

Specifically, the collector 210 grips the upper end when mounted on the case 400, inserts the lower end into the guide groove, which is the space between the protrusions 930, and inserts it into the groove 810, and grips the upper end when detaching. After that, it can be completely separated from the case 400 by pulling it out upward. Therefore, it has a very simple detachable structure.

Meanwhile, as described above, in the collector module 200, a plurality of collectors 210 are connected to each other through a connecting member (not shown). At this time, the connecting member has a tong-type terminal at the end like an alligator clip, so that the connection between the collectors 210 is easy and modularization is also easy.

Since the collector 210 is a component in which particles charged by corona discharge are collected on the surface, the collector 210 is a consumable item that needs to be replaced because the dust collection power is lowered after the dust is collected to a certain extent, and it needs to be cleaned or replaced periodically.

In this embodiment, the collector 210 has a structure in which the lower end is inserted into the groove 810 and the protruding part 930 guides the collector 210, so it is convenient to attach and detach, and thus it is easy to replace with another collector module 200. In other words, it is used for one time use and maintenance through replacement is easy. Alternatively, since it is convenient to attach and detach, it is possible to perform simple maintenance by taking it out from the case 400 upwards, washing it, and then inserting the lower part into the guide groove, which is the space between the protrusions 930, and inserting it into the groove part 810.

Therefore, according to the present invention, while collecting particles charged by corona discharge, maintenance is easy through simple removal/installation of the structure in which particles are collected, and ozone disappears even when operated in an enclosed space such as indoors, so that the ozone concentration is reduced to the standard value. An ion wind air purifier having a grill structure that does not affect the amount of air purification while promoting user safety is provided.
