Description

Cluster ion generating drive apparatus

The present invention relates to a cluster ion generating device, and more particularly, to a cluster ion generating device for positively and negatively releasing positive and negative ions in air by forming a positive electrode and a negative electrode. By changing and improving the shape, a clean mode that deodorizes harmful substances contained in the air by controlling the output voltage according to the operation mode or an ion mode that provides a forest bath function by anion by minimizing cation generation can be selectively selected as necessary. The present invention relates to a cluster ion generating device capable of easily controlling the discharge amount of negative ions and positive ions emitted in the clean mode and the ion mode.

As is well known, with the development of society, most of modern people have a long time to live in the enclosed interior, which keeps the indoor air fresh.

Therefore, in most homes, offices, vehicles, or public facilities that are used by the public, a separate air purifier is installed to purify the air to convert the indoor air into healthful air.

However, most air purifiers (or air purifiers) use a method of filtering impurities contained in the air through various filters and supplying clean air to the room.

However, since such air cleaners absorb air in the space and adsorb or decompose contaminants by the filter, maintenance such as replacement of the filter is necessary for long-term use, and the characteristics of the filter are insufficient. Satisfactory performance is not obtained.

On the other hand, air purifiers and air conditioners that increase the concentration of ions in the air using ion generators have been developed. However, since most commercially available products generate only negative ions, the effect of relaxing humans by negative ions is As can be expected, such a conventional ion generating device generates negative ions from a discharge needle by a direct current high voltage method or a pulse high voltage method, and therefore requires a high voltage of 5 kV or more as an applied voltage. As a result, there is a problem that a lot of dust is attached to the product or peripheral devices, or because of the use of high voltage, there is a problem in the safety of the device, and it is necessary to take measures such as installing a safety circuit.

In particular, there was a risk of generating ozone, which is known to adversely affect the human body in the process of generating negative ions.

Therefore, by applying a high-voltage alternating current (AC voltage), negative ions are generated in the negative ion generating unit having the negative electrode (-), and positive ions are simultaneously released in the positive ion generating unit having the positive electrode (+), such as dust and tobacco smoke. Hazardous substances in the air are adsorbed with negative ions and moved to the surrounding cations to perform deodorization, as well as generating electrons with negative charges and holes with positive charges. It creates super oxide ion, hole oxidizes water and creates radicals of hydroxyl groups, so that the super okiside and hydroxyl radicals have strong oxidative decomposition effect, killing bacteria and removing odors. It has been disclosed.

As a representative example, Republic of Korea Patent No. 0502121 (registered, name: sterilization method, ion generating device, ion generating device and air conditioner), Republic of Korea Patent Publication No. 2006-10230 (2006.2.2. , Name: ion generator), Republic of Korea Patent No. 0812540 (Registered on March 3, 2008, Name: Generator and method of generating ion cluster), Republic of Korea Patent No. 0823496 (Registration of April 4, 2008, Name: Ion Generation) Air purification apparatus and air purification method), and the like.

However, the above-described inventions employ a plasma discharge method or an electron radiation method to generate anions and cations. Particularly, in the case of employing an electron radiation method, in the discharge needle, a brush is formed on the anion generator. It took the shape and the cation generation part formed the polygonal pyramid or the cone shape so that anion generate | occur | produces much more than cation.

Therefore, the above-described ion generators have a disadvantage in that the function of controlling the discharge amount of the negative ions and positive ions emitted by controlling the output voltage according to the operation mode is weak.

On the other hand, as is well known, the vehicle is provided with an air conditioner (hereinafter simply referred to as "air conditioner") or a heater for appropriately adjusting the room temperature regardless of the outside temperature.

The air conditioner for the air conditioning of the vehicle interior is a driving unit which receives the driving force from the engine which is the driving source of the vehicle and drives it, and heats it with a cooling unit that cools the inside of the vehicle in the cooling state and the engine coolant and heats the interior of the vehicle with the air conditioner in the heating state. It is composed of separate.

The cooling unit and the heater unit as described above are assembled into a single unit through an assembling process to be connected to the room from the engine room of the vehicle body and constitute one vent duct providing a flow path of cooling and heating air.

In addition, a blower unit is additionally coupled to the duct configured as described above, thereby forcibly circulating air in the vehicle interior, thereby achieving air conditioning of the desired vehicle interior.

On the other hand, when the air conditioner or the heater as described above is operated in the vehicle, external air or indoor air introduced through the intake duct passes through the blower to prevent heat exchange from the evaporator core installed in the evaporator or the heater core installed in the heater. It is converted into cold air or hot air and supplied to the vehicle interior through the vent duct.

At this time, in order to prevent external pollutants from entering the room, the air filter installed at the front or rear of the blower is to filter the outside air.

However, contaminants such as dust or foreign matter collected in the air filter remain until the air filter is replaced. If the driver does not replace the air filter for a long time, the odor enters the vehicle interior due to the occurrence of mold. In addition, there was a problem that the pollutants excessively collected in the air filter is introduced into the room through the air filter.

In addition, due to the moisture generated in the evaporator core during the operation of the air conditioner, the surface of the evaporator core provides conditions suitable for mold or bacteria to inhabit the mold and bacteria, etc., resulting in the odor generated as it is indoors. There was also a problem that the inflow, the concentration of the driver is reduced by the pollution of the air due to such odors and pollutants, there was a problem that causes discomfort and various diseases.

Thus, in order to solve the above problems, the Republic of Korea Patent No. 0812540 (registered on March 3, 2008, name: generating device and method of generating ion clusters), Republic of Korea Patent No. 0823496 (registered on April 4, 2008, Name: An ion generating air purification device and an air purification method) have been proposed and mounted on a vehicle cluster ion device.

Further, as a cation ^{_{H + (H 2 O) m}} O 2 as the anion (m is a natural ^number), and sends out these ions at the same time to generate the (H ₂ O) _{n (n} is a natural number) into the air, These ions have a function of killing bacteria suspended in the air by an oxidation reaction of hydrogen peroxide (H ₂ O ₂ ) or an OH group (radical) as an active species produced by a chemical reaction. As a result, the air can be improved to be beneficial to health without floating bacteria.

On the other hand, the mechanism of sterilization and removal of suspended bacteria in the air by the action of anions and cations causes plasma discharge by applying an alternating voltage to the dielectric. the monohydrate H ⁺ (H ₂ O) _m are generated, negative ions as oxygen ion hydrate O ₂ ^- the (H ₂ O) _n are generated. At this time, m and n are both arbitrary natural numbers.

As described above, when anions and cations are attached to the surface of airborne bacteria, the active species generates hydroxyl (OH) or hydrogen peroxide (H ₂ O ₂ ) to extract and sterilize hydrogen atoms from the cells of the bacteria. In addition, this chemical reaction is an oxidation reaction, and the hydroxyl group (OH) not only sterilizes but also oxidizes and deodorizes various molecules that are sources of odor contained in the air.

The cation generator 61 and the anion generator 62 generate cations and anions, respectively, and the cation generator 61 and the anion generator 62 are electrically connected to the high pressure unit 60 to be described later. Each is connected.

In this case, as shown in FIG. 2, the amount of ions generated by forming the cation generator 61 and the anion generator 62 in different shapes may be different.

In particular, the amount of the positive and negative ions generated in the cation generator 61 and the anion generator 62 is the shape of the discharge needle (6a, 6b), the distance between the discharge needle (6a, 6b) and the output voltage And the like can be adjusted as variables.

Each of the discharge needles 6a and 6b constituting the cation generator 61 and the anion generator 62 may be configured in various ways, and at least one conventional anion generator generates at least one anion. It was formed in the shape of a brush including a pin, including a carbon material, and the cation generating part was formed of a conical rod or a polygonal cone of polygonal pyramid, one end of which was made of a metallic material.

However, the present invention is characterized by changing the shape and material of the discharge needle in order to be able to easily adjust the amount of ion generation according to the operation mode described above.

That is, the shape of each discharge needle (6a, 6b) applied to the cation generator 61 and the anion generator 62 according to the present invention, as shown in Figures 3 to 5, the end of the plate The discharge needle 6a of the cation generator 61 has one or more pointed pin portions.

Usually, ions are known to be released into the atmosphere through a sharp point. In a preferred embodiment of the present invention, the discharge needle 6a of the cation generator 61 has a shape in which a plate is formed to have three pointed pin portions. Have.

The discharge needle 6b of the anion generator 62 has an equal or several pointed pin portions than the discharge needle 6a of the cation generator 61.

In the first preferred embodiment of the present invention, the discharge needle 6b of the anion generator 62 has a shape in which the plate shape is processed to have six pointed pin portions.

At this time, the discharge needle (6a, 6b) may be made of any metal material that is easy to release the ion, such as platinum, stainless, copper, nickel, manganese, tungsten.

In addition, according to the present invention, when the discharge needles 6a and 6b are manufactured in a plate shape, the fastening structure is improved to facilitate the fastening and assembly work of the discharge needles 6a and 6b.

That is, the other end of the discharge needle of the plate-shaped end is processed is connected to the transformer 2 of the high-pressure section to be described later to receive a high voltage, as shown in Figures 3 and 4, the discharge needle (6a, 6b) ) Is connected to a transformer (2) providing a high voltage on the printed circuit board (PCB) (3).

Here, in the present invention, the other ends of the discharge needle (6a, 6b) of the discharge needle (6a, 6b) structure is configured as a clip fastening type having elasticity so that the discharge needle (6a, 6b) can be easily assembled on the printed circuit board Having one characteristic.

That is, as shown in FIG. 5, free ends opposite to the discharge needles 6a and 6b, each of which has a sharp pin shape, are fitted on the fastening holes 4 and 5 formed in the printed circuit board 3, respectively. Simply put, the curved hook portion 7 having elasticity to be fastened, a seating portion 8 which is horizontally bent at the end of the hook portion 7, and an end thereof have the same height as the seating portion 8. It is comprised by the stopper part 9 in which the discharge needles 6a and 6b plate surface was partially cut and the tension was formed.

Here, the hook portion 7 is formed in a curved structure so as to have elasticity by bending upwardly one end portion of the discharge needles 6a and 6b, and the entire hook portion 7 has a slightly curved shape. The elastic force is to be doubled.

In addition, the seating part 8 has a structure in which the end of the upwardly bent hook part 7 is bent horizontally once again to the opposite side.

As formed, when the discharge needles 6a and 6b are respectively inserted into the fastening holes 4 and 5 on the printed circuit board 3, the stopper portion 9 is further inserted together with the seating portion 8. It restricts the seating while limiting.

That is, when the hook portion 7 of the discharge needle (6a, 6b) is inserted into the fastening holes (4, 5) on the printed circuit board 3, the curved hook portion (7) is pressed while being inserted, so inserted When the seating portion 8 and the stopper portion 9 of the discharge needles 6a and 6b come into contact with the upper surface of the printed circuit board 7, the insertion of the discharge needles 6a and 6b is simple and the insertion is restricted. This is done.

On the other hand, the discharge needles 6a and 6b having a pin shape in the same plate shape as the first embodiment of the present invention may be formed by cylindrical discharge needles 6c and 6d, as shown in FIG. .

That is, FIG. 6 shows an example of use in which the discharge needles 6c and 6d according to the second embodiment of the present invention are formed in a cylindrical shape and assembled on the main body 1.

As described above, the plurality of pointed pin-type discharge needles 6a, 6b, 6c, 6d can be manufactured in a plate shape or a cylindrical shape.

It is arranged in a cylindrical shape to have a pointed pin part.

On the other hand, the experimental results of confirming the degree of generation of ions by changing the shape of the discharge needle (6a, 6b), (6c, 6d) according to the present invention is well shown in the experimental data of FIG.

That is, the experimental data of FIG. 8 shows that each of the discharge needles 6a, 6b and 6c, 6d is driven in a clean mode at 25 ° C and 50% humidity at 25 mm intervals. This is an experimental data that looks at the amount of change in the amount of ions by number.

As shown in the experimental data, the amount of cations released from the cation generator 61 according to the combination method of the number of pins of the discharge needles 6a, 6b, and 6c, 6d is negative. It can be seen that the amount of the anion released from the relatively smaller or larger than.

According to the cluster ion generator according to the present invention, the number of discharge needles 6a and 6b that can easily perform the required operation mode could be selected and designed.

On the other hand, the cation generating unit 61 and the anion generating unit 62 is known that it is preferable to be spaced apart at intervals of 10 to 40 mm, since the generation amount of ions also varies depending on the installation interval.

That is, in FIG. 9, the cation generator 61 and the anion generator 62 show the results of experiments confirming the degree of generation of ions according to the installation intervals.

In the experimental data shown in FIG. 9, the amount of cations released from the cation generator 61 according to the installation intervals of the discharge needles 6a, 6b and 6c, 6d is determined by the amount of negative ions released from the anion generator 62. It could be confirmed that the amount can be relatively smaller or larger than the amount, and based on the results of these experiments, the discharge needle (6a, 6b), (6c, 6d) shape (combination method of the number of discharge needle pins) according to the present invention With a single variable, etc.), it is possible to implement a specification that can more easily achieve the operation mode to be implemented by the cluster ion generating device.

As shown in FIG. 7, in the cluster ion generator according to the present invention, the filter unit 10 is, for example, a varistor connected between a positive terminal and a ground terminal drawn out from a connector (IN) for DC power input. The varistor (VAR) is responsible for protecting circuit devices at the rear end by blocking static electricity or surges flowing through the power line.

On the other hand, the reverse voltage protection unit 70 may be implemented as a diode (D1) connected in parallel to the varistor (VAR), that is, connected in the forward direction between the (+) terminal and the ground terminal. When the electrode is inserted into the connector (IN) in reverse, the power is cut off to protect the circuit elements of the rear end.
