The present invention relates to a cluster anion generator using a ceramic block and a method of manufacturing a ceramic block, and more particularly, to a cluster anion generator and a cluster anion generator for generating the same cluster ion as a natural state without generating ozone. A method for producing a ceramic block to be mounted.

Anion means negative electricity among the invisible particles with electricity. Recently, various products applying the anion have been introduced due to various useful effects of the anion. Representative examples include anion air purifiers, which remove various contaminants in the indoor air and generate negative ions and discharge them together with the purified air to maintain a more comfortable environment. In addition, it is utilized in various sterilizers.

Conventionally, as a mechanism for generating negative ions, the principle of corona discharge, discharge by electron-radiating negative electrode needle, or plasma discharge is applied. Specifically, in the case of the corona discharge method, when a high voltage is applied between two electrode plates spaced apart from each other, a rapid current flows due to dielectric breakdown, and negative ions are generated in this process. In addition, in the case of plasma discharge, a halogen-based gas loses electrons by using microwaves and high-frequency, such as ionizing radiation or vacuum ultraviolet rays having high energy, and generates negative ions. Instead, a needle-shaped sharp conductor is used as a negative electrode, and a high pulse voltage is applied to the negative electrode to emit electrons directly into the air.

At this time, since the anion generally has a much lower movement speed than the electron, the generated anion and the anion in the electron combine with the cation to be recombined, and the electrons remaining in the process combine with oxygen in the atmosphere to generate ozone. As a result, most of the generated anions bind to and disappear with the cations in the air, so that not only the number of anions that can be delivered to the human body is substantially smaller, but also negatively affect the human body due to ozone generated as a by-product.

As an alternative to this problem, Korean Utility Model Registration Application No. 20-2002-0037697 discloses an anion generator that processes eight metal components such as platinum, stainless steel, copper, silver, zinc, nickel, manganese and tungsten, and free electrons. Consists of a conductive cloth, a conductive rubber and a semi-conductive rubber material having a, it is proposed a negative ion generating device configured in the form of a twisted fiber form wound around the body of the negative ion generator.

In the above, the electrical energy is converted into thermal energy to cause corona discharge into the air through a constant resistance, so that spark discharge is not performed. In this process, moisture in the air is decomposed into hydrogen and hydroxyl groups, and as a result, cluster ions are identical to those of natural anions. To generate Through this, not only ozone is generated, but also to generate cluster ions that can exist in the air for a longer time, it is possible to increase the efficiency delivered to the human body.

However, as shown in the utility model, not only is there a loss of energy in the process of converting electrical energy into thermal energy, but also the structure of the negative ion generating unit is completely different from that of a conventional device, making manufacturing difficult and costly. In addition, the surface of the anion generator is contaminated when used for a long time, the contaminated portion is not in contact with the atmosphere has a disadvantage that the production efficiency is significantly reduced.

In order to solve the above problems, the applicant has disclosed an integrated negative ion generator of a type filled with porous particles between two electrode plates. According to the anion generator, the anion discharged through the electrode plate has increased motility while passing between the porous particles to become a nuclear ion with improved reactivity, the released nuclear ion is combined with acid molecules and water molecules in the air By allowing cluster ions to form, they are able to move for long periods of time while maintaining an electrically negative state, without undergoing immediate ions decay or recombination with cations. This makes it possible to provide a larger number of negative ions to the indoor space.

However, in the technique disclosed in this application, the voltage applied to the pole plate to generate negative ions reaches about 3000 to 3500 V, and the circuit located around by the magnetic field formed around the pole plate when such a high voltage is applied to the pole plate In addition, it will adversely affect adjacent appliances and computers. In addition, when the user contacts the electrode plate or the like during use or A / S, there is a problem that does not cause great harm to the human body, but gives a very unpleasant feeling.

The present invention is to overcome the disadvantages of the prior art as described above, to further improve the applicant's prior art to provide an anion generator that can generate a larger amount of negative ions than the prior art as a technical problem.

In addition, the present invention is to provide a negative ion generator capable of generating a sufficient degree of negative ions even when a low voltage is applied as compared to the prior art.

In addition, another object of the present invention is to provide a method for manufacturing a ceramic block installed in the anion generator as described above.

In order to achieve the above technical problem, the present invention, the case having a separate first and second internal space; And an anion generator and an anion converter mounted in the first and second internal spaces, respectively, the anion converter comprising: a pair of pole plates attached to an inner wall of the second internal space; It includes a ceramic block located between the pole plate, one of the pole plate is connected to the negative electrode of the negative ion generating portion, the other pole plate provides an anion generator characterized in that it is connected to the lead for anion emission.

Although the present invention employs some of the principles of the applicant's preliminary application, most of the electrons discharged from the electrode can pass through the inside of the ceramic block by using a ceramic block instead of conventional porous particles. In this way, the amount of the cluster anion finally produced is increased. That is, in the past, electrons pass through the spaces between the particles as well as the pores of the particles, so that some of the electrons do not have sufficient reactivity and thus are not converted into cluster anions. It can generate a large number of negative ions.

Preferably, the negative voltage of the negative ion generating unit is -1500 ~ -2000V. That is, in the present invention, since a larger number of cluster anions are generated, it is not necessary to apply a high voltage of 3000 V or more as in the prior art, and it is possible to prevent the magnetic field generated by the high voltage from affecting the circuit.

Preferably, the thickness of the ceramic block is preferably at least half the height of the electrode plate. More preferably, the thickness of the ceramic block is greater than the height of the electrode plate. Through this, it is possible to minimize the discharge of electrons discharged through the electrode plate to the outside without passing through the ceramic block.

Here, the ceramic block is a weight ratio

SiO ₂ : 90 to 95%, Al ₂ O ₃ : 1 to 3%, Fe ₂ O ₃ : 0.5 to 1.5%, CAO: 0.1 to 0.5%, MGO: 0.03 to 0.1%, and the balance containing impurities It is good.

The present invention also provides a weight ratio

SiO ₂ : 90 to 95%, Al ₂ O ₃ : 1 to 3%, Fe ₂ O ₃ : 0.5 to 1.5%, CAO: 0.1 to 0.5%, MGO: 0.03 to 0.1%, and the balance containing impurities Doing; Heating the mixed mixture at a temperature of 100 to 300 ° C. for 2 to 4 hours; Mixing the heated mixture with an organic binder; Injecting the mixture mixed with the binder into a mold; Pressing to mold into a mold in a mold; And it provides a method for producing a ceramic block for the negative ion generator comprising the step of firing the molded semi-finished product at a temperature of 800 ~ 1200 ℃.

In the above process, in order to fire the semi-finished product with sufficient hardness, the process must be carried out at a temperature of 800 to 1200 ° C as disclosed, and there is a possibility that the inherent properties of the ceramic mixture may be lost at such a high temperature. . Therefore, the present invention adds a process of alkali metalizing the metal components included in the mixture by heating the mixture at a relatively low temperature of 100 to 300 ° C. for 2 to 4 hours prior to firing, and thus the alkali metallized metal component. In addition to releasing its own magnetic field, the preheating coating layer is created on the surface of each particle constituting the mixture, so that each unique property, such as a magnetic field, can be maintained even in the subsequent firing process. Make sure

Hereinafter, with reference to the accompanying drawings will be described in detail an embodiment of a negative ion generator and a method of manufacturing a ceramic block using a ceramic block according to the present invention.

1, an embodiment of an anion generator using a ceramic block according to the present invention is shown. The embodiment 100 basically includes a main body 110 having a rectangular box shape and a cover 102 covering the main body 110. The main body 110 may be formed of a plastic resin material, the cover 102 may be detachably coupled to the main body 110, may be integrally bonded using an adhesive or the like.

One side of the main body 110 is provided with a conductive wire 112 connected to the pole plate, which will be described later, and an electrode needle 114 for emitting negative ions is attached to an end of the conductive wire 112.

Referring to FIG. 2, the partition wall 120 is positioned inside the main body 110, and the interior of the main body 110 is divided into first and second internal spaces based on the partition wall 120. In FIG. 2, the negative ion generating unit is located in the first internal space located to the left of the partition wall 120. The negative ion generating unit is a device for applying an external power source to convert the high voltage to a pole plate 124 to be described later, and includes a plurality of devices mounted on a printed circuit board. Since the negative ion generating unit may utilize a known high voltage generating unit, the description thereof will be omitted.

The negative ion generating unit is sealed with silicon 122 to protect the circuit from external impact or the like. Meanwhile, two pole plates 124 and 126 are mounted at both ends of the second inner space located to the right of the partition wall 120. A pole plate 124 positioned adjacent to the first inner space among the pole plates is connected to an output end of the negative ion generator. Therefore, electrons generated by the negative ion generator are discharged to the second internal space through the electrode plate 124.

The discharged electrons are introduced into the ceramic block 128. The ceramic block 128 has the same rectangular shape as that of the second internal space and has a plurality of pores therein. Therefore, as electrons pass through the pores in the ceramic block 128, the reactivity is improved, and the electrons having such enhanced reactivity are emitted to the outside through the electrode plate 126 located on the opposite side. The electrons thus released combine with acid and water molecules in the air to form cluster anions.

Referring to FIG. 3, the ceramic block 128 is shown. The ceramic block 128 shown in FIG. 3 is composed of one block, but may have a form in which a plurality of blocks having a thin thickness are stacked. In the case of targeting a plurality of main bodies having different thicknesses, there is an advantage in that a plurality of standardized blocks can be stacked.

The components of the ceramic block and the composition ratio (wt%) are as follows.

MGO: 0.07

Al ₂ O ₃ : 2.01

SiO ₂ : 93.65

CAO: 0.29

Fe ₂ O ₃ : 0.99

Na ₂ O: 2.75

P ₂ O ₅ : 0.02

SO ₃ : 0.01

Cl: 0.01

K ₂ O: 0.11

TiO ₂ : 0.09

MNO: 0.01

The ceramic block is first mixed with materials to have the composition as described above, and then heated at a temperature of 100 to 300 ° C. for about 2 to 4 hours. Thereafter, the heated mixture is mixed with an organic binder to inject a raw material mixture into a mold having a predetermined shape. When the injection is completed to form a ceramic block as shown in Figure 3 by pressing or molding by pressing more than 30 tons or extrusion of more than 100 tons.

The molded ceramic block may be fired at 800 to 1200 ° C. in a kiln to obtain a finished ceramic block. The pore size of the ceramic block thus made is 0.2-0.4 microns, and the porosity is 70% or more. In addition, when a high-voltage oscillator of 3000V or more is contacted, a balanced current flow is generated, not only to generate high-quality negative ions, but also to generate no scattered electromagnetic waves. As a result of the measurement, it was confirmed that more than twice the cluster anions were generated compared to the conventional products, and sufficient anions were obtained even when the voltage was dropped to about 2000V.

According to the present invention having the configuration as described above, not only can generate a larger number of cluster anions, but also lower the voltage applied to the electrode plate, thus affecting the negative ion generator itself and various electronic products located around it. It can be reduced to increase the stability of the device.

In addition, since a plurality of porous blocks, rather than porous particles, are mounted between the electrode plates, there is an advantage of easy handling.
