Description

TECHNICAL FIELD The present invention relates to a deodorizer for a refrigerator and a method for manufacturing the deodorizer,

The present invention relates to a deodorant for a refrigerator and a method for producing the same, and more particularly, to a deodorant for a refrigerator and a method for producing the same, The present invention relates to a deodorant for a refrigerator which can reduce the fishy flesh stored in the refrigerator through far infrared rays and anions radiated to the outside and soften the meat quality and maintain the freshness of the vegetables for a long time.

It is already well known that storage of food generally inhibits microorganisms and enzymatic actions which are the cause of deterioration and corruption. Therefore, refrigeration, freezing, storage at room temperature, storage of gas, and salting are used as measures to prevent deterioration and decay of food, but refrigeration is the most widely used method at home.

However, such a refrigeration method does not completely inhibit the growth of microorganisms, the respiration of living beings and vegetables, and the proliferation of various enzymes. Therefore, when preserved for a long period of time, there is a possibility that food stagnation due to microbial growth, It causes occurrence and deterioration. Therefore, researches for increasing the shelf life of food while eliminating the main cause of deteriorating the quality of food in the refrigerator have been actively carried out. The research has been carried out by a biological method using a specific enzyme, a chemical method of treating a specific medicament, Has been actively performed as a physical method of extending the storage period with an excellent adsorbent or the like.

In addition, deodorants, which are impregnated with metal salts in porous materials such as active carbon and zeolite, and deodorizers made of metal salts and organic acids, which are mainly used as refrigerator deodorants, are currently used. However, Low efficacy and low persistence.

Particularly, activated carbon used as a deodorizer for refrigerator is excellent in initial deodorizing power, but deodorant power is rapidly lowered when particles which adsorb odor to a porous article are adsorbed and become saturated as time elapses.

In addition, the activated carbon contained in the refrigerator from the factory is used to transport the refrigerant to the consumer through the use of pentane, hexane, ethylacetate, ethyl benzene, toluene, toluene and so on. Therefore, there is a problem of deterioration in performance at the time of initial use in which the deodorizing function can not be properly exhibited when the consumer uses the activated carbon. Such activated carbon has low antibacterial, sterilization and freshness maintenance functions.

In foreign countries, a photo-plasma generator, an ultraviolet ray generating LED, an ozone generator or anion air filter are installed for the purpose of deodorizing or antibacterial and sterilizing a refrigerator, but an electric wiring work and installation space are required. Strong ozone, ultraviolet rays, and the like can damage the human body, which requires a shielding device, which increases the production cost.

SUMMARY OF THE INVENTION The present invention has been conceived to solve the problems described above, and it is an object of the present invention to provide a refrigerator which can be produced by mixing a yellow loam powder, a quartz andesite powder and an additional mineral, The present invention provides a deodorizer for a refrigerator and a method of manufacturing the same, which can reduce the fishy smell stored in the refrigerator through far infrared rays and negative ions radiated from the smell of the odor and smooth the meat quality and maintain the freshness of the vegetables for a long time.

It is also an object of the present invention to provide a deodorant for a refrigerator which can effectively increase the deodorizing power and adsorption power by adding and mixing additional minerals having micropores among the raw materials of 1,000 sources, and a process for producing the same.

It is also an object of the present invention to provide a deodorant for refrigerator which enables compression molding by putting the prepared raw material into a mold and a method of manufacturing the same.

It is also an object of the present invention to provide a deodorant for a refrigerator and a method of manufacturing the same, which enables injection molding through a plastic injection molding method.

In order to achieve the above object, in one aspect,

(a) preparing a raw material comprising at least one of loess and quartz inlaid (dacite); (b) molding the raw material; And (c) firing the molded raw material. The present invention also provides a method for manufacturing a deodorant for a refrigerator.

Hereinafter, each step will be described in detail.

(a) Yellow loess ( loess ) And quartz andesite dacite ) To prepare a raw material containing at least one of

In the present invention, the term " raw material " refers to all kinds of minerals that can be formed into a mold of a deodorant for a refrigerator, and in particular, minerals such as loess and quartz oresite (dacite) May be included therein. This is because the loess and quartzite andesite naturally release anion or far-infrared rays at room temperature without any additional external energy, so there is no cost for anion or far-infrared emission and space for installation of anion emission equipment is unnecessary. In addition, the loess and quartz andesite are easily available in the surrounding area, so the supply rate is excellent.

Here, loess is mainly composed of SiO2, Al2O3, Fe2O3, K2O, TiO2, MgO and P2O5 with large porosity, and is loosely cured by calcium carbonate and can be easily obtained all over Korea. Such loess has no harmful effect on living organisms, has high far infrared ray emissivity, has high physical properties such as dioxin adsorption and water purification ability.

However, when yellow loess is collected directly from the land and used without any pretreatment process, not only the bacteria and fungi contained in the loess but also the impurities cause the chemical reaction to generate toxic gas. Furthermore, the yellow loess itself has low far-infrared emissivity, low anion generation, and low strength after firing.

Therefore, it should not be used only as the loess itself. Crushing and plastic working should be carried out by mixing quartz andesite containing Al2O3, CaO, Fe2O3, Na2O, Na2O, ZrO2, MnO, Cr2O3, Rb2O, etc. and crushing them to 300 mesh or more.

The step (a) comprises the steps of: (a1) concentrating the loess and quartz andesite; (a2) mixing the loess and quartz andesite; (a3) grinding the mixed loess and quartz andesite; And (a4) adding and mixing additional minerals including one or more of clay minerals, titanium dioxide (TiO2), aerobic minerals and quicklime.

In addition, the mixing ratio of the loess and the quartz andesite can be 2: 8 to 8: 2.

In addition, it is preferable to crush the loess and the quartz andesite so that the powder diameter is 300 mesh or more. The reason for this is to increase the strength of the deodorant for the refrigerator by increasing the binding force of each component when baking at high temperature because the components of the loess and quartz andesite are different.

Also, the step (a4) may include 40 to 80% by weight of the loess and the quartz andesite powder; 5 to 25% by weight of the clay mineral; 10 to 15% by weight of at least one of the above titanium dioxide, sodium sulphate and quicklime; And 5 to 25% by weight of water (H2O) are mixed for 3 to 4 hours.

At this time, the aerobic part is provided to prevent the air bubbles generated during agitation and aging of the deodorant composition and to tightly bond the tissue, and it is preferable that 1 to 2 parts by weight of 100 parts by weight of water is included.

If the content of the aerobic part is less than 1 part by weight, bubbles may be generated during agitation and aging of the composition for an interior material, so that the texture of the interior material may not be tightly bonded.

On the contrary, when the content of the aerobic part is more than 2 parts by weight, the bonding force for the interior material is not improved, and there is a possibility that adverse effects on other physical properties are exerted. Therefore, it is preferable to add 1 to 2 parts by weight of the content of fatty acids.

In addition, when the quicklime is in contact with water, a large amount of water can be absorbed into a large number of minute pores, thereby causing a hydration reaction. This hydration reaction is one of the most effective grinding processes. As a result of the hydration reaction, Ca (OH) 2 has a very high expansion force as compared with CaO, and after several minutes depending on the amount of binding water, a dispersion fine slurry Phase. The aggregation of these fine particles can increase the bonding force during the drying process and shorten the drying time of the ceramic. Also, the higher the purity and the powderiness of the quicklime itself, the more the drying time shortening effect can be increased.

In addition, the quicklime may have a CaO purity of 85 to 90% and MgO of 1% or less, and more preferably, the quicklime is contained in an amount of about 3 to 5%, especially 4%, based on the total weight of the raw material.

(b) molding the raw material

The step (b) includes a step of compressing at least one of the clay minerals, the clay minerals, the titanium dioxide, the aerated soot and the quicklime and the water mixed in the step (a4) into a mold .

In the step (b), at least one of the clay minerals, the clay minerals, the titanium dioxide, the aerated soot, and the quicklime mixed in the step (a4) and 10 to 10% by weight of the acrylonitrile butadiene styrene (ABS) Suzy; And 10 to 15% by weight of a PS (Poly Styrene) resin; May be added and mixed to effect injection molding.

Through such injection molding, the deodorizer for refrigerator is mainly used in refrigerator to remove the odor inside and to maintain the freshness of the stored food. By activating the water constituting the living thing, the food is fresh, Softened, and the odor of the refrigerator can be removed to improve the taste of the food.

c) Molded  Raw materials Fired  step

Wherein the step (c) comprises: (c1) drying and aging the raw material for 7 days; And (c2) calcining the dried and aged raw material at a temperature in the range of 800 to 960 degrees for 20 to 30 minutes.

In another aspect, the present invention relates to a deodorant for a refrigerator manufactured by the above-described method for manufacturing a deodorant for a refrigerator.

In the present invention, a deodorant for a refrigerator can be formed in the form of a circular box having an interior hollowed out by the above-described manufacturing method, and one or more holes can be formed on a lower side.

It should be noted that, in the present invention, the outer shape of the deodorant for refrigerator may correspond to a circular box shape, but it can be deformed to any other shape at the stage of molding the raw material.

According to the present invention, when a deodorant for a refrigerator is applied to a refrigerator, adsorption and deodorizing power is increased by silicon dioxide (SiO2) having a porosity of 40% or more, adsorbed odor components can be decomposed continuously, It has an effect of extending the food storage period by generating far infrared ray which suppresses the existing enzyme action.

According to the present invention, when a deodorant for a refrigerator is applied to a refrigerator, the content of free water is reduced while the water binding force in the food is increased, so that the effect of inhibiting microbial growth in the food can be obtained.

Further, according to the present invention, by lowering the enzymatic action existing in the food itself, the shelf life of the food is improved and the food is more easily aged.

Further, according to the present invention, the storage period of the food is extended by the far-infrared rays emitted from the deodorant for refrigerator, and Escherichia coli, ordinary bacteria and fungi can be captured while being adsorbed in the porous deodorant space, Can be suppressed. In addition, it has an effect that the deodorizing function and the freshness keeping function can be maintained semi-permanently.

<Specific Review>

As in Experimental Example 1, the content of silicon dioxide (SiO2) was the highest at 58.31%, followed by aluminum oxide (Al2O3) at 26.21%. In addition, the clay was composed of titanium dioxide (TiO2), magnesium oxide (MgO), phosphorus pentoxide (P2O5), calcium oxide (CaO), sulfur trioxide (SO3), sodium oxide (Na2O), zirconia (ZrO2) and manganese oxide (MnO).

Here, silicon dioxide (SiO2) belongs to silicon clay minerals, has a honeycomb-shaped multilayer structure, and the inner sponge shape has a structure capable of absorbing and emitting far infrared rays and anions.

Therefore, since yellow loess contains such a large amount of silicon dioxide (SiO2), it can absorb and emit far-infrared rays and anions.

Here, the far infrared ray may mean an infrared ray having a wavelength of 4 탆 or more and a wavelength of longer than that of a red region of a visible ray as a kind of electromagnetic wave. Therefore, such infrared rays are not visibly recognized by the human eye, are well absorbed by the material, and are characterized by strong resonance and resonance action on the organic compound molecules.

Also, light generally has a good reflection when its wavelength is short, and it has a property of being absorbed well when it reaches a long body, so it has a strong penetrating power, so that a human body is also warmed by this infrared ray. For example, in a water of 30 ° C, it hardly feels a warm aura. However, when you sit at the same temperature, you can feel warmth because the far infrared rays contained in the sun penetrate deep into the skin to generate heat. Helps to eliminate the germs that cause it, and it helps to expand blood capillary blood circulation and cell tissue formation. In addition, when it comes into contact with moisture and protein molecules that make up the cells, the cells are shaken 2,000 times per minute to activate cell tissue, which is effective in preventing aging, promoting metabolism and preventing chronic diseases such as chronic fatigue. It has excellent effects on facilitating action, relieving pain and eliminating heavy metals, preventing sleeping and deodorization, preventing the growth of antibacterial and fungi, and dehumidifying and air purification, so that it can be used for various purposes such as housing and building materials, kitchen utensils, textile, clothes, bedding, It is used in the field.

Here, the negative ion may mean a material in which a neutral particle becomes a negative charge, in which electrons are generated. These anions are known to have various beneficial effects on the human body and the like. For example, it cleanses the blood in the human body, regulates the autonomic nervous system, activates cells, and promotes resistance. It helps mental stability and recovery of health, helps to overcome stress, and improves brain function. have.

In addition, it was found that when the anion environment is provided to animals, the development is promoted, and in case of chicken egg scattering, the egg size is increased and the population is increased. On the other hand, in the case of plants such as crops, it is known that when grown in an anion environment, development is promoted and the number of fruits to be harvested is increased. In addition, it is advantageous for antibacterial action to remove air pollution and bad smell, and also shows effects on water pollution, and recently, products using anion are getting popular spotlight.

On the other hand, when the loess is directly used without being subjected to the pretreatment process, the bacteria, fungi and impurities in the loess can be chemically reacted and generate toxic gas.

Further, since yellow loess can not emit a large amount of anions and far-infrared rays by itself, and loose strength after firing, yellow loess is preferably mixed with quartz andesite, which will be described later.

As shown in Experimental Example 2, the content of silicon dioxide (SiO2) was the highest at 63.42%, followed by aluminum oxide (Al2O3) at 17.39% and calcium oxide (CaO) at 3.84 Respectively. In addition to this, it is also possible to use a mixture of 3.73% iron oxide (Fe 2 O 3), 3.36% sodium oxide (Na 2 O), 2.38% potassium oxide (K 2 O), 2.13% phosphorus pentoxide (P 2 O 5), 0.54% magnesium oxide TiO2), zirconia (ZrO2), and manganese oxide (MnO) accounted for 0.54%, 0.11%, and 0.09%, respectively.

Here, since quartz andesite also contains silicon dioxide (SiO2) in the same way as yellow clay, it can absorb and emit far-infrared rays and anions.

As in Experimental Example 3, the deodorizing power of the deodorant for refrigerator according to the present invention was analyzed. As a result, the gas concentration (ppm) with respect to formaldehyde (HCHO) became lower and the concentration (ppm) of the sample became lower.

Here, (CH) N, which is most frequently detected in a domestic refrigerator, is an odor component in fish smell, and CHSH is acidic as a component of kimchi smell.

As can be seen from these results, it can be seen that the deodorant for refrigerator according to the present invention works very effectively in removing formaldehyde gas.

As shown in Experimental Example 4, the gas concentration of the deodorizer according to the present invention over time according to the deodorizing power of the deodorant according to the present invention is 19.2% for the gas and 0.41% for the moisture content of the deodorant for the refrigerator according to the present invention, .
