An air conditioner is a concept that includes a cooling device (air conditioner) that cools and circulates air, and a heating device (heater) that heats and circulates air. A circulation fan is usually installed inside the main body, which has an inlet and an outlet, and connects the inlet. It sucks in indoor air through the main body, cools or heats the inhaled air, and then discharges it back into the room through the outlet. Usually, air conditioning and heating devices are manufactured and sold as separate products, but recently, cooling and heating devices that can perform both cooling and heating as a single device have been used. The air conditioner used in this specification may be understood as a concept including an air conditioning device, a heating device, and an air conditioning device.

A detachable filter is built into the inlet side of the main body of such an air conditioner to filter out foreign substances such as dust contained in the inhaled air. This filter is usually in the form of a mesh net or net made of plastic (PP).

Recently, as interest in indoor air quality has increased, precision filters (such as HEPA filters or nano filters) used in air purifiers are used in air conditioning and heating devices. However, in this case, the cost is high and there is a hassle of cleaning or replacing the filter. Therefore, it is common to purchase and use a separate air purifier.

Meanwhile, the following prior art document discloses an external filter attached to the outer surface of the intake port of an air circulator. This external filter uses a filter member such as a HEPA filter or activated carbon filter to suction a plate-shaped support member in which a plurality of intake holes are formed. It is tightly provided on the inner surface of the hole or on one side of the support member by heat fusion or the like, and has a structure in which an adhesive is provided on the other side of the support member (the side facing the suction port).

However, this prior art uses a relatively expensive filter member such as a HEPA filter or activated carbon filter, and the filter member must be fixed to the support member by heat fusion or the like, which has the problem of increasing manufacturing costs. In addition, since a plate-shaped support member is applied, it can be relatively easy and sturdy to attach to a stand-type air conditioner, but when applied to a wall-mounted air conditioner with a curved inlet shape, it may be difficult to attach and may not be sturdy.

The above objects, features and other advantages of the present invention will become more apparent by describing the preferred embodiments of the present invention in detail with reference to the accompanying drawings. Hereinafter, a nonwoven filter for an air conditioner or heater according to an embodiment of the present invention will be described in detail with reference to the attached drawings.

Figures 1 and 2 are diagrams showing a non-woven fabric filter for an air conditioner or heater applied to a stand-type air conditioner (30) according to an embodiment of the present invention, and Figure 3 is a diagram showing a nonwoven fabric filter for an air conditioner or heater applied to a wall-mounted air conditioner (30).

Referring to Figures 1 to 3, the non-woven filter for an air conditioner or heater according to an embodiment of the present invention includes a non-woven filter member 10 installed to cover the front of the inlet 32 of the air conditioner 30, and a non-woven filter member 10. It includes fixing means (20) for fixing to the outer surface of the main body of the air conditioner (30).

The non-woven filter member 10 has a substantially rectangular shape in plan, but is not necessarily limited thereto. However, since the suction port 32 of the air conditioner 30 is mostly arranged in a rectangular structure, it is preferable that the nonwoven filter member 10 covering it also has a substantially rectangular shape in plan. Here, the front of the intake port 32 of the air conditioner 30 refers to the outer surface of the air conditioner when viewed from the outside.

Therefore, when the air conditioner operates, indoor air flows into the air conditioner 30 through the non-woven filter member 10 and the intake port 32, and at this time, contaminants contained in the air (for example, microorganisms and odor, etc.) It is filtered through this non-woven filter member (10). The material and components of the non-woven filter member 10 will be described later.

Referring to Figures 1 to 4, the fixing means 20 includes an annular ring 22 and an attachment member 24 provided near the four corners of the non-woven filter member 10.

The annular ring 22 refers to a ring having a closed structure such as a circular or oval shape. In the embodiment of the present invention, it is illustrated that the annular ring 22 is provided near the four corners of the non-woven filter member 10, but the present invention is not limited to this, and if necessary, for example, it can be added to the long side of the rectangle. It can be provided with .

The material of the annular ring 22 is not limited to a specific material, and a fabric material such as a regular string may be used, and may also have a stretchy elastic material (for example, a rubber band). When the annular ring 22 is made of a stretchy elastic material, installation convenience improves, and the non-woven filter member 10 can be installed more closely to the intake port. Meanwhile, the circular ring can be made into a circular loop with a closed structure as in the present invention by making a straight string and tying it with a knot, etc.; however, in this case, the user may feel uncomfortable, so it is better to make it in the form of a circular ring during manufacturing.

The attachment member 24 has a hook 25 on which the annular ring 22 is attached at the front, and an attachment means 26 attached to the outer surface of the main body of the air conditioner 30 at the rear. The attachment means 26 is not limited to any one that can be attached to the main body of the air conditioner, and various embodiments may be applied. For example, a magnet may be applied, an adhesive tape (sticker) or an adhesive material may be applied, or Suction pads, etc. may be applied.

Meanwhile, according to another embodiment of the present invention, the fixing means may be a double-sided tape provided on four corners of one side of the non-woven filter member 10, that is, the side facing the inlet 32 of the air conditioner. If the fixing means is double-sided tape (sticker), it can be installed in additional places other than the four corners. However, when the fixing means 20 is applied as a double-sided tape, the adhesion or fixing force may be weakened compared to the previous embodiment, and there is a possibility that the attachment position may be limited. Therefore, the fixing means is illustrated in FIGS. 1 to 4. It is desirable to apply a fixed fixing means.

Therefore, the user determines the installation location by roughly placing the non-woven filter member 10 in front of the air inlet of the air conditioner, and attaches the attachment member 24 to the air conditioner body at a corresponding appropriate position so that the non woven filter member 10 does not droop. and fix it. Afterwards, installation is completed by hanging the annular ring 22 on the locking ring 25 of the attachment member 24. In this way, by providing the annular ring 22 to the non-woven filter member 10 and properly attaching the attachment member 24 on which the annular ring 22 hangs to the air conditioner, convenience of installation is increased regardless of location, and the non-woven filter member is sturdy. It can be attached easily.

The nonwoven fabric applied to the nonwoven filter member 10 of the present invention is manufactured by carding, crosslapping, and needle punching single fibers of composite fibers including polyethylene terephthalate (PET) fibers and low melting fibers. It is characterized in that it is manufactured in a first process, and a second process in which the nonwoven fabric produced in the first process is coated with an antibacterial and deodorizing material and heat treated.

Specifically, the first process is a step of manufacturing a web by carding single fibers, cross-lapping, and then needle punching to produce a non-woven fabric.

Since the conventional technology for producing nonwoven fabric by carding, cross-lapping, and needle-punching the short fibers is well known, detailed components and methods will be omitted.

At this time, the short fibers include PET and LM. The PET (polyester terephthalate) has a melting point of 260°C and a length of 3d, 51mm. In addition, LM (Low melting fiber) is characterized by a melting point of 110°C and a length of 5d and 51mm.

At this time, the mixing ratio of the PET and the LM is preferably 8 for PET and 2 for LM.

The needle punching consists of a pre-punching machine and a main punching machine, and is characterized by needling in one vertical direction of the web. In addition, the main stroke number of the needle punching is 1000 to 1400 (stroke/min), preferably 1200 (stroke/min).

The nonwoven fabric produced by the first process has a weight of 60 to 80 g/m ² , preferably 65 to 75 g/m ² , more preferably 68 to 72 g/m ² , and most preferably 70 g/m ² . If the density of the non-woven fabric is less than 60 g/m ² , when air is sucked through the non-woven filter member 10 installed to cover the front of the inlet 32 of the air conditioner 30, some of the harmful microorganisms in the air pass through and the present invention It is difficult to achieve the purpose, and if the density of the non-woven fabric exceeds 80 g/m ² , the suction of air through the non-woven filter member 10 installed to cover the front of the inlet 32 of the air conditioner 30 is not sufficient. There is a problem with the air conditioner being overloaded.

The second process is a step of coating the nonwoven fabric manufactured in the first process with an antibacterial and deodorizing material and heat treating it.

The antibacterial and deodorizing material is a newly developed material by the present inventor, and refers to filtered water obtained by extracting and maturing rice husk liquid and aqueous silicon solution and then filtering them. Specifically, the rice husk liquid is a material obtained by heating and carbonizing rice husk and then liquefying it, and the silicon aqueous solution is a material obtained by maturing a mixture of kaolin and clay in purified water and then filtering or fractionating it. The filtered water does not contain harmful substances and has excellent antibacterial and deodorizing effects.

As a specific example, as a result of requesting the Korea Institute of Chemical Convergence to analyze and measure hazardous substances for the filtered water according to the present invention, lead (Pb), arsenic (As), mercury (Hg), antimony (Sb), cadmium ( Cd), dioxin, formaldehyde, and pathogens such as Pseudomonas aeruginosa and Staphylococcus aureus were not detected at all, confirming that it was harmless to the body (see Figure 8).

Below, the rice husk solution and silicon aqueous solution mentioned above will be described.

Rice husk liquid is obtained by heating and carbonizing rice husk and then liquefying it. The main raw material, rice husk, is the husk or outer husk of rice and is also called maejomit bran. When rice husk goes through the carbonization process, it creates countless pores like fine honeycombs, the surface area of which is more than 200 pyeong per gram, and because it is in the shape of the rice husk itself, it has excellent adsorption and breathability. Additionally, because it has a dense structure and many pores, it selectively absorbs harmful substances. In other words, as the cell wall of the rice husk burns, numerous microscopic pores are created, and these pores can function to selectively absorb harmful viruses or toxins by exerting strong adsorption power.

Silicon aqueous solution is obtained by placing a mixture of kaolin and clay in purified water, maturing it, and then filtering or fractionating it. Kaolin, the main raw material, is created when feldspar minerals in rocks or soil are chemically weathered by carbonic acid or water. It is called by various names such as kaolin, kaolin, red clay, and white clay. The most commonly produced mineral species include kaolinite (Al2O3·2SiO2·2H2O) and halloysite (Al ₂ O ₃ ·SiO ₂ ·4H ₂ O), as well as nacrite and dickite. ) is also produced, although it is rare. This kaolinite does not undergo substitution at the tetrahedral and octahedral sites, so SiO ₂ 46.54 %, Al ₂ O ₃ 39.50 %, H, which does not significantly deviate from the theoretical crystal structure of Al ₄ Si ₄ O ₁₀ (OH) 8 It has a chemical composition close to _2O 13.96%, and in addition to the main elements, Fe, Ti, K, and Mg are also detected, and these are known to mostly replace octahedral Al ³⁺ . Kaolinite has a 1:1 layer structure in which one tetrahedral plate and an octahedral plate are combined, and when kaolinite is heated to a high temperature of 550 ℃ or higher, dehydration occurs and the crystal structure is destroyed, resulting in low crystallinity. In addition, clay, another main raw material, is mainly composed of hydrated aluminum and silicon oxide, and is a secondary mineral created when rocks undergo weathering and other processes. Such clay is a layered mineral that can contain water in its crystal structure, and is a material with good plasticity that is easy to shape according to particle size, particle shape, and moisture content. However, when dried or heat treated, it loses its properties and turns into a hard and brittle material. Depending on its structure, its chemical and physical properties are very diverse, and in addition to aluminum and silicon, it also contains elements such as iron, magnesium, or manganese. Kaolin and clay can be mixed and used at a weight ratio of 7:1 to 5, preferably 7:2 to 4, more preferably 7:3.

In the present specification, the rice husk liquid and the silicon aqueous solution can be mixed and used at a weight ratio of 1: 1 to 3, preferably 1: 1.5, and the non-woven filter member of the present invention is used in an amount sufficient to achieve the efficacy or activity of the filtered water. Since there are no side effects or toxicity to the human body even when administered in excessive amounts, the upper quantitative limit on the amount of filtered water used can be adjusted and applied by a person skilled in the art within an appropriate range. As an example, filtered water coated on the non-woven filter member according to the present invention can be used by mixing purified water. In this case, filtered water and purified water can be mixed at a weight ratio of 1:10 to 20.

Meanwhile, among the terms used in this specification, “filtered water” is obtained by extracting and maturing rice husk liquid and aqueous silicon solution and then filtering them, as described above. For example, filtered water is obtained by passing it through a filtration membrane with a certain molecular weight cut-off value. Fractions obtained through various additional purification methods, such as separated fractions and various chromatographic separations, may also be included in the filtered water of the present invention.

The method for producing the antibacterial and deodorizing material according to the present invention includes preparing a rice husk solution (S10), preparing an aqueous silicon solution (S20), and mixing and stirring the rice husk solution and the aqueous silicon solution to prepare a mixed solution. It includes a step (S30), a step of extracting the mixed solution and then maturing it by adding a catalyst (S40), and a step of filtering the mixed solution (S50).

Here, the step of preparing the rice husk liquid includes the step of removing impurities present on the surface of the rice husk (S11), the step of carbonizing the rice husk by heating (S12), and the step of liquefying the rice husk (S13). In addition, the step of preparing the silicon aqueous solution includes washing the mixture of kaolin and clay (S21), placing the mixture in purified water and aging it (S22), and filtering or fractionating the mixture (S23). Includes.

Hereinafter, the method of manufacturing the above-described antibacterial and deodorizing material will be described in detail according to the drawings.

Figure 5 is a process chart for explaining a method for producing an antibacterial and deodorizing material according to the present invention, Figure 6 is a process chart for explaining a method for producing rice husk liquid according to an embodiment of the present invention, and Figure 7 is a process chart for explaining the method for producing a rice husk liquid according to an embodiment of the present invention. This is a process diagram for explaining a method of producing a silicon aqueous solution according to another embodiment of the invention.

Referring to Figures 5 to 7, first, rice husk liquid is prepared (S10).

The method of producing rice husk liquid removes impurities present on the surface of rice husk as shown in Figure 6 (S11).

Rice husk can be prepared by removing impurities such as dirt, sand, stone dust, etc. from the surface by spraying air or by washing them several times in running water so as not to affect the carbonization and liquefaction process, which will be described later. In addition, it is prepared by grinding with any equipment selected from a ball mill, attrition mill, jet mill, rotary mill, and vibration mill. It's okay too.

Afterwards, the rice husk is heated and carbonized (S12).

The rice husk from which impurities have been removed in step S11 may be heated to 600 to 1000° C., preferably 750 to 850° C., to carbonize the rice husk to remove lignocellulose such as cellulose. If the carbonization temperature is less than 600°C, it may be difficult to remove cellulose, which is a cellulose, and if it exceeds 1000°C, mineral components may be denatured.

Finally, the rice husk is liquefied (S13).

The rice husk that has completed carbonization in step S12 can be liquefied by applying pressure, preferably 5KG, under conditions of 50 to 300 ° C, preferably 100 to 200 ° C. If the temperature is less than 50°C, it may be difficult to extract the active ingredient, and if the temperature exceeds 300°C, the active ingredient may be denatured by heat, which is undesirable.

Afterwards, an aqueous silicon solution is prepared (S20).

In the step of preparing an aqueous silicon solution, the mixture of kaolin and clay is washed as shown in FIG. 6 (S21).

Kaolin and clay are mixed at a weight ratio of 7:1 to 5, preferably 7:2 to 4, more preferably 7:3, and then mixed so as not to affect the maturation and filtration or fractionation processes described later. It can be prepared by washing foreign substances on the surface several times under running water. In addition, it is prepared by grinding with any equipment selected from a ball mill, attrition mill, jet mill, rotary mill, and vibration mill. It's okay too.

The mixture is then placed in purified water and aged (S22).

The mixture washed in step S21 can be added to purified water and aged at a temperature of 50 to 200 ° C, preferably 80 to 150 ° C for 1 to 5 days, preferably 2 to 4 days. If the aging period is less than 1 day, it may be difficult to obtain silicate crystals with a particle size of 0.2 to 0.6 nanometers, and if it exceeds 5 days, the particle size may increase to 1.0 to 4.0 nanometers, which is not desirable.

Finally, the mixture is filtered or fractionated (S23).

The mixture aged in step S22 may be filtered or fractionated by either filtration through a filter or high-speed rotation separation using a centrifugal separator.

Afterwards, the rice husk solution and the silicon aqueous solution are mixed and stirred to prepare a mixed solution (S30).

The rice husk liquid prepared in step S10 and the silicon aqueous solution prepared in step S20 are mixed at a weight ratio of 1: 1 to 3, preferably 1: 1.5, and then mixed at 20 to 40 RPM, preferably 25 to 35 RPM. It can be stirred for 12 to 36 hours, preferably 20 to 30 hours. If the ratio of the silicon aqueous solution is less than 1, the sterilizing and antibacterial effects may be low, and if it exceeds 3, the antiviral effect may not be very great due to the addition of more than necessary silicon aqueous solution.

Next, the mixed solution is extracted, a catalyst is added and aged (S40).

The mixed solution prepared in step S30 is subjected to high-pressure liquid extraction using any equipment selected from a heating stirrer, high-temperature pressurizer, or extruder (pressure molding machine), and then added with a catalyst and aged for 1 to 3 days, preferably 2 days. You can.

As the catalyst, any one of platinum, alumina, iridium, or silver can be used, preferably a silver catalyst.

Finally, the mixed solution is filtered (S50).

Select one of the following methods: rapid filtration, slow filtration, filtration using sterilized gauze, paper filter or glass filter, and high-speed rotation separation using a centrifuge, etc., in which the mixed solution aged in step S40 is passed through a filter medium at a speed of 120 to 200 m. Thus, filtration can be performed.

The filtered water obtained in this way is an aqueous solution from which impurities have been removed and is not only a substance with antiviral, sterilizing and antibacterial properties, but also has a deodorizing effect and emits far-infrared rays.

The filtered water prepared in the same manner as above, that is, the antibacterial and deodorizing material according to the present invention, is diluted 10 to 30 times, preferably 10 to 25 times, and more preferably 10 to 20 times in purified water in the second process and coated. do. The coating can be done by conventional methods, for example, by dipping or spraying.

The coated nonwoven fabric is subjected to heat treatment, which is performed at 60 to 95°C, preferably 65 to 95°C, for 1 to 5 minutes, preferably 1 to 4 minutes, more preferably 1 to 3 minutes, using hot air, etc. Heat treat by the method.

Through this series of coating and heat treatment processes, the antibacterial and deodorizing substances are well adsorbed to the nonwoven fabric, and even after a long period of time, the antibacterial and deodorizing substances are not removed from the nonwoven fabric and can maintain their effectiveness.

After the second process, a step of cutting the nonwoven fabric manufactured by the second process may be additionally included.

The cutting is to manufacture the nonwoven fabric into a desired shape and size. For example, it can be cut into a square shape and a size that can cover the intake port of a stand-type air conditioner.

The non-woven filter member 10 manufactured by the above method is harmless to the human body and exhibits antibacterial and deodorizing effects due to the adsorbed antibacterial and deodorizing substances.

Specifically, the present inventor commissioned the non-woven filter member 10 manufactured above to the Korea Far-Infrared Application Evaluation Institute and conducted an antibacterial test against Staphylococcus aureus and pneumoniae. As a result, it showed an antibacterial effect of more than 99.9% (see FIG. 9).

In addition, the present inventor commissioned the Korea Far-Infrared Application Evaluation Institute to test the deodorizing effect of the non-woven filter member 10 manufactured above and confirmed that the deodorizing rate was excellent (see FIG. 10).

In addition, the present inventor commissioned the non-woven filter member 10 manufactured above to the Korea Far-Infrared Application Evaluation Institute and tested the far-infrared ray emission effect. As a result, it was confirmed that the non-woven filter member 10 emits far-infrared rays (see FIG. 11) ).
