Description

CLEANING TOOL{A CLEANING TOOL}

The present invention relates to a cleaning tool, and more particularly, to a cleaning tool capable of effectively removing scale and dirt generated on the surface of an object.

In general, high-strength metal or ceramic materials are used for tableware such as bowls or cups, washbasins, toilet bowls, bathtubs, or tiles installed in bathrooms or toilets to improve ease of maintenance and appearance quality derived from the texture of the material. is produced by

These dishes or washbasins have the advantage that they are not easily corroded or damaged by the use of various detergents or cleaning tools because they are coated with a thin glaze made of glassy material to prevent moisture absorption or surface contamination. , Scale can easily form on the surface as moisture dries due to the nature of the environment of use, which is always exposed to moisture.

Scale is formed when trace minerals contained in tap water react with various pollutants or detergents, and deposits adhere to and accumulate on the surface of dishes or washbasins, and cannot be easily removed with general detergents and cleaning tools. It is removed using a tool such as a scraper.

The scraper is configured to be equipped with a blade made of a plastic or metal material, and the user applies pressure to the blade to scrape foreign substances such as scale through the sharp edge of the blade. It consists of a scraper body with blades formed like an arc, and a handle connected to the body.

Since the components that make up the scale are not easily decomposed with general detergents, it is difficult to remove the scale generated on the surface of dishes or washbasins with a conventional scraper. In addition, if scale is removed using a plastic or metal scraper, the glaze of the finished surface layer made of ceramic is removed together, and fine grooves are generated on the surface of dishes or washbasins. There was a problem that scale easily gets stuck and the appearance quality is greatly deteriorated.

In contrast, Korean Patent Registration No. 10-2049702 discloses that a scraper of a cleaning tool consisting of a scraper, a fixed portion to which the scraper is fixed, and a grip connected to the fixed portion to serve as a handle is laminated in multiple layers of polyethylene and ethylene vinyl alcohol copolymer. Disclosed is a cleaning tool for removing scale from a ceramic material such as a tableware or a washbasin, in which a number of irregularities are formed on both sides of a blade at the end of a scraper to improve a scale removal effect.

However, when such a cleaning tool is applied together with a detergent, it is difficult to generate foam from the detergent, and it is difficult to uniformly interpose the detergent and the foam derived from the detergent on the interface between the scraper and the washing object, and the detergent before the foam is generated. There is a problem that is removed by the scraper. In addition, since the plurality of irregularities located on both sides of the blade at the end of the scraper are formed in only one direction, it is inevitable to apply the cleaning tool in a specific direction when removing scale, that is, the application direction of the cleaning tool is in the direction of the unevenness. There is a problem that it is inconvenient to use because it is limited by the

The present invention is to solve the problems of the prior art described above, and an object of the present invention is to have excellent compatibility with detergents, to be conveniently used without restrictions according to directions, and to reduce water resistance on the surface of the object to be washed. It is to provide a cleaning tool that can effectively remove scale by mitigating it.

Hereinafter, the present invention will be described with reference to the accompanying drawings. However, the present invention may be embodied in several different forms, and thus is not limited to the embodiments described herein. And in order to clearly explain the present invention in the drawings, parts irrelevant to the description are omitted, and similar reference numerals are attached to similar parts throughout the specification.

Throughout the specification, when a part is "connected" with another part, this includes not only the case where it is "directly connected" but also the case where it is "indirectly connected" with another member interposed therebetween. . In addition, when a part "includes" a certain component, this means that other components may be further provided without excluding other components unless otherwise stated.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic diagram of a cross-section of a cleaning tool according to an embodiment of the present invention, and FIG. 2 is a schematic diagram of a front cross-section of a waterproofing layer according to an embodiment of the present invention.

1 and 2 , a cleaning tool 100 according to an aspect of the present invention includes an elastic body 110 ; and a waterproofing layer 120 provided on at least a portion of the surface of the elastic body, wherein the surface of the waterproofing layer includes a first protrusion 131 and a second protrusion 132, and the first and second protrusions are A cleaning tool spaced apart by a first interval 133 of 0.1 to 200 mm is provided.

The elastic body 110 may include a soft material, preferably a porous material, that provides cushioning, shape restoration, and shape change properties to the cleaning tool. The soft porous material may be, for example, one selected from the group consisting of sponges, rubber, nonwoven fabrics, fabrics, foams, and combinations of two or more thereof, and may preferably be sponges, but is not limited thereto.

The elastic body 110 allows the shape of the cleaning tool to be easily deformed according to the shape of the surface of the object to be cleaned, and enhances the adhesion between the surface of the object to be cleaned and the waterproof layer 120 to improve the effect of removing scale.

In particular, when the cleaning tool 100 is used to remove scale from the inside of the dish, a curved surface with a small radius of curvature is formed at the boundary between the side surface and the bottom of the dish. When washing the curved surface inside the dish, the elastic body 110 is As it deforms according to the curved shape of the inside of the dish, the waterproof layer 120 is brought into close contact with the inner surface of the dish, so that scale can be effectively removed.

The waterproof layer 120 and the first and second protrusions 131 and 132 may be integrally formed. Specifically, the waterproof layer 120 and the first and second protrusions 131 and 132 may be made of the same and/or the same material and/or in a manner such as bonding, sealing, or bending without any space therebetween. can be interconnected by In addition, the first and second protrusions 131 and 132 may be formed by pressing the waterproof layer 120 with a roll having a corresponding pattern, a stamp, or a member similar thereto. The member and/or the waterproof layer 120 may be heated.

A thin layer of glaze made of glassy material is applied to the surface of metal or ceramic tableware or washbasin to prevent moisture absorption or surface contamination, and to improve the appearance quality. When using a scraper or blade to remove scale from ceramic dishes or washbasins, the sharp edge of the blade can easily damage the glaze surface layer, and friction occurs in the contact area with the blade, which makes it difficult to use a cleaning tool. As the blade does not completely adhere to the surface of the tableware or washbasin, scale cannot be easily removed. In contrast, the waterproof layer 120 and the first and second protrusions 131 and 132 integrally formed with the waterproof layer 120 and the first and second protrusions 131 and 132 may perform a role of removing scale by coming into close contact with and in contact with the surface of the object to be washed.

The waterproof layer 120 and/or the first and second protrusions 131 and 132 may be made of a moisture-impermeable material. As used herein, the term "moisture impermeability" refers to a property that does not substantially pass or permeate water, moisture, and moisture, and the moisture impermeable material may be non-porous and/or porous. When the moisture-permeable material is porous, the minimum size of the pores may be smaller than the minimum size of water, moisture, and moisture droplets generated during washing and cleaning.

For example, the waterproof layer 120 may be made of a plastic barrier laminate (PBL) material including a core layer containing ethylene vinyl alcohol, and a skin layer formed on at least one surface of the core layer and containing polyethylene. . The PBL is a soft material and has strong corrosion resistance, so that when the scale is removed using the cleaning tool 100, mineral components or various contaminants included in the scale are not easily transferred or adhered to the surface of the waterproof layer 120. .

The PBL is mainly used in containers such as toothpaste or cosmetics, and since the container discarded after the toothpaste or cosmetics is exhausted can be reused as it is, or it can be reused after appropriate post-treatment, it is not only eco-friendly but also used in the production of cleaning tools. cost can be reduced.

The waterproof layer 120 made of the PBL can reduce frictional force with the object to be cleaned, and has a property of being easily deformed in the direction to which a force is applied while having a hard surface. It can be used to attach to curved surfaces such as dishes or washbasins to easily remove scales created on the surface. In addition, the waterproof layer 120 can prevent the surface of the object to be washed from being damaged, thereby effectively preventing the regeneration of scales on the damaged surface after washing.

The waterproof layer 120 and the first and second protrusions 131 and 132 formed integrally therewith may include an antibacterial agent. For example, the antimicrobial agent is suitably dispersed inside the waterproof layer and/or the first and second protrusions, is properly applied to the surface of the waterproof layer and/or the first and second protrusions, or a combination thereof. can

The antibacterial agent may be one selected from the group consisting of inorganic antibacterial agents, organic antibacterial agents, metal antibacterial agents, ammonium salt antibacterial agents, guanidine antibacterial agents, copper compound antibacterial agents, sustained release polymer antibacterial agents, natural antibacterial agents, and combinations of two or more thereof.

The organic antibacterial agent is mainly in a liquid state, and has the advantage of exhibiting an immediate antibacterial effect by preventing the formation of a colony of bacteria rather than sterilization, so it can be added to products requiring antibacterial activity in a short time. The durability of antibacterial activity is temporary, and the organic antibacterial agent can be thermally decomposed under high temperature conditions, so it cannot be applied.In addition, it can generate resistant bacteria and threaten human safety because of its high acute toxicity. may be one selected from the group consisting of thiabendazole, isothiazole, zinc pyrithione, imidazole, carbendazole, tricholonic acid, and a combination of two or more thereof, but is not limited thereto.

The natural antibacterial agent is a substance frequently encountered in daily life, and it induces user friendliness and has the best human safety. Efficiency may be reduced. The type of the natural antimicrobial agent may be one selected from the group consisting of mulberry bark, grapefruit seed, bamboo, fig, mugwort, aloe, ginseng, phytoncide, green tea, and a combination of two or more thereof, but is not limited thereto.

The inorganic antibacterial agent has low initial antibacterial activity, but unlike the organic antibacterial agent, human safety and thermal stability are high, resistant bacteria are not generated, and antibacterial durability is almost semi-permanent, so the range of use can be broadly applied compared to the organic antibacterial agent. The inorganic antibacterial agent may be one selected from the group consisting of zeolite, calcium phosphate, zirconium phosphate, and a combination of two or more thereof, and preferably, silver (Ag), zinc ( Zn), copper (Cu), manganese (Mn), such as a metal ion having excellent antibacterial activity may be substituted. Since the inorganic antimicrobial agent has a three-dimensional skeleton structure with fine pores, it has a large specific surface area and excellent heat resistance. In particular, the zeolite-based antibacterial agent is the most widely used because of the high metal ion support. In addition, the zeolite-based antibacterial agent does not have a discoloration problem compared to other antibacterial agents, and has advantages such as high antibacterial power, high safety, and low particle hardness. On the other hand, the calcium phosphate-based antibacterial agent has a disadvantage in that the concentration of the metal ion to be substituted is low, and thus the antibacterial activity is lower than the concentration of the metal ion to be substituted is low compared to the zeolite-based antibacterial agent.

The metal ion may be selected as needed, but preferably silver (Ag). The silver (Ag) has excellent antibacterial activity, is non-toxic and non-irritating to the human body, and has excellent chemical durability and heat resistance. In addition, since silver ions can be released over a long period of time, antibacterial durability is excellent.

The waterproof layer 120 may have a thickness of 0.1 to 10 mm. The thickness of the waterproof layer may be changed, for example, according to the number of core layers and/or skin layers constituting the PBL. If the thickness of the waterproof layer is less than 0.1mm, durability may be reduced, and if it exceeds 10mm, the feeling of use, compatibility with detergents, and washing power may be reduced accordingly.

The first and second protrusions may be spaced apart from each other by a first interval 133 of 0.1 to 200 mm. The first gap 133 may be defined as a thickness of a dividing line dividing the first protrusion 131 and the second protrusion 132 adjacent thereto in a plan view of the waterproof layer 120 . The size of the first gap may be adjusted in the range of 0.1 to 200 mm, preferably 0.1 to 100 mm, more preferably, 0.1 to 50 mm, depending on the size of the waterproofing layer according to the application target of the cleaning tool. have. If the first gap 133 is less than 0.1 mm, it is not possible to secure the minimum surface roughness required to remove scale, and the resistance by water on the surface of the object to be washed is increased, so that scale cannot be effectively removed. Rather, it is difficult to form a gap between the projections. On the other hand, when the first gap 133 is greater than 200 mm, the number of protrusions per unit area and the corresponding surface area of the protrusions become small, so that scale cannot be effectively removed.

3 is a schematic diagram of a side cross-section of a waterproofing layer according to an embodiment of the present invention, and FIG. 4 is a schematic diagram of a pattern (plan view) of protrusions (parts) according to an embodiment of the present invention.

Referring to FIG. 3 , the first and second protrusions 131 and 132 may include two or more protrusions 1311 formed in a predetermined pattern, respectively, and the two or more protrusions have a second interval of 0.1 to 10 mm ( 134) can be separated.

The height of the protrusion 1311 may be 0.1 to 10 mm. The height of the protrusion may be changed according to, for example, the number of core layers and/or skin layers constituting the PBL. If the height of the protrusion is less than 0.1 mm, scale cannot be effectively removed, and if it exceeds 10 mm, the feeling of use may be reduced when the cleaning tool is directly held by hand without a separate grip.

The second gap 134 is an interval between adjacent protrusions among two or more protrusions included in the first protrusion 131 and/or between adjacent protrusions among two or more protrusions included in the second protrusion 132 . means the interval. If the second gap 134 is less than 0.1 mm, it is not possible to secure the minimum surface roughness required to remove scale, and the resistance by water on the surface of the object to be washed is increased, so that scale cannot be effectively removed. Rather, it is difficult to form a gap between the projections. On the other hand, if the second gap 134 is greater than 10 mm, the number of protrusions per unit area and the corresponding surface area of the protrusions become small, so that scale cannot be effectively removed.

A cross-sectional area of a lower end of the protrusion may be greater than a cross-sectional area of the upper end. For example, the upper end of the protrusion may be round-treated (FIG. 3(b)) or may be molded into a needle shape (FIG. 3(c)), and may have a combined shape, but is not limited thereto. . When the cross-sectional area of the lower end of the protrusion is larger than the cross-sectional area of the upper end, the lower end of the protrusion 1311 provides support and fixing force during washing, while the middle and upper ends of the protrusion 1311 provide flexibility and cleaning power accordingly. have.

Referring to FIG. 4 , the first protrusion 131 and the second protrusion 132 may have the same pattern as each other, and may have different patterns if necessary. In addition, the protrusions included in the first protrusion 131 may be formed in the same pattern, or may be formed in different patterns, if necessary. In addition, the protrusions included in the second protrusion 132 may have the same pattern or, if necessary, may have different patterns.

The first and second protrusions 131 and 132 are spaced apart by the first interval and, if necessary, may be formed to cross one or more times, and FIG. 4 shows the first and second protrusions 131 and 132. ) indicates a pattern that is crossed twice. 4, the first protrusion 131 has a plurality of protrusions having a straight pattern arranged in parallel, and the second protrusion 132 has the same pattern as the first protrusion 131 (Fig. 4(a)). )), a plurality of protrusions having a straight pattern displaced from the first protrusion 131 are arranged in parallel (Fig. 4(b)), or a plurality of protrusions having a curved pattern are arranged in parallel (Fig. 4(c)), It may be formed of a plurality of protrusions having a concentric circle pattern (FIG. 4(d)).

Although not shown, in the second protrusion 132 , a plurality of protrusions having a straight pattern are arranged in parallel, and the first protrusion 131 has the same pattern as the second protrusion 132 , or the second protrusion A plurality of protrusions having a straight pattern displaced from (132) may be arranged in parallel, a plurality of protrusions having a curved pattern may be arranged in parallel, or may be formed of a plurality of protrusions having a concentric circle pattern.

5 is a schematic diagram of a cross-section of a cleaning tool according to another embodiment of the present invention. Referring to FIG. 5 , the cleaning tool 100 includes an elastic body 110 ; and a waterproofing layer 120 provided on the surface of the elastic body to seal the elastic body. In addition, although not shown in FIG. 5 , the surface of the waterproof layer 120 includes a first protrusion 131 and a second protrusion 132 , and the structures and shapes of the first and second protrusions are shown in FIGS. 2 to It is the same as described above with reference to FIG. 4 . At least one end of the waterproof layer 120 may further include a sealing part 121 for sealing the elastic body, and the sealing part 121 is sealed so as not to be irreversibly opened and closed by a method such as adhesion or compression. It may also be sealed so that it can be reversibly opened and closed by a method such as a zipper, Velcro, or adhesive. Preferably, by allowing the sealing part 121 to be reversibly opened and closed, the elastic body 110 and/or the waterproof layer ( 120) can be easily replaced.

In addition, the sealing part 121 may be processed by a sealing part (not shown) made of a soft member. The hardness of the sealing part may be smaller than the hardness of the waterproof layer, and in this case, the cushioning, shape restoration and shape change characteristics of the cleaning tool 100 due to the stress concentrated at the boundary of the sealing part 121 are reduced. It can complement, improve, and reduce the risk of trauma to the user.

The sealing part may include rubber, and if the hardness of the sealing part can be made smaller than that of the waterproof layer, the type thereof is not particularly limited. In addition, since the waterproof layer 120 removes scale and the sealing unit removes moisture from the object to be washed, the cleaning effect can be maximized. The sealing part may be variably separated and combined with the cleaning tool 100 .

6 is a schematic diagram of a cross-section of a cleaning tool according to another embodiment of the present invention. Referring to FIG. 6 , the support 140 may be embedded in the elastic body 110 . The support 140 may have one shape selected from the group consisting of a coil, a plate, a rod, a sphere, and a combination of two or more thereof, but is not limited thereto. In addition, if necessary, the support 140 may be provided in two or more inside the elastic body 110 . In addition, the support 140 may be embedded along the thickness direction of the elastic body 110 or may be embedded along the area direction (or radial direction) of the elastic body 110 , and if necessary, the elastic body 110 . ) may be embedded along the thickness direction and the area direction (or radial direction). In addition, by attaching both ends of the support 140 to the inner surface of the waterproof layer 120 , the support 140 may be fixed at a predetermined position of the elastic body 110 .

The support 140 can further enhance cushioning, shape restoration and shape change characteristics by the elastic body 110, and in particular, complement and strengthen the durability of the elastic body 110 made of a soft porous material. .

7 is a schematic diagram of a cross-section of a cleaning tool according to another embodiment of the present invention. Referring to FIG. 7 , the cleaning tool 100 may include one or more through-holes 150 penetrating through the elastic body 110 and the waterproof layer 120 in a thickness direction. The through hole 150 may further enhance cushioning, shape restoration, and shape change characteristics of the cleaning tool by the elastic body 110 . In addition, the through hole 150 may increase the overall surface area of the cleaning tool 100 so that moisture remaining on the surface and inside of the cleaning tool 100 after cleaning can be more effectively removed.

A ratio of the cross-sectional area of the through hole 150 to the cross-sectional area of the cleaning tool 100 may be 0.01 to 0.5. Specifically, the diameter of the through hole 150 may be 0.01 to 0.5 times the diameter of the cleaning tool, preferably, 1 to 10 cm, but is not limited thereto. If the diameter of the through hole 150 is less than 0.01 times the diameter of the cleaning tool, it is difficult to strengthen the cushioning, shape restoration and shape change characteristics of the cleaning tool, and if it exceeds 0.5 times, the area of the waterproofing layer 120 in contact with the cleaning object Since this is relatively small, the cleaning efficiency may be reduced.

In addition, the waterproof layer 120 may be provided to extend to the surface of the through hole 150 , and the waterproof layer 120 provided on the surface of the through hole 150 may be disposed along the thickness direction of the cleaning tool 100 . It may include the formed unevenness 160 . The unevenness 160 may further enhance cushioning, shape restoration, and shape change characteristics of the cleaning tool by the elastic body 110 . In addition, the unevenness 160 can improve the feeling of use when the washing tool is directly held and used without a separate grip, and the compatibility with the detergent is significantly improved, such as easily generating bubbles when applied with the detergent. can be improved

The unevenness 160 may include two or more unit unevenness. The height of the unit unevenness may be 0.01 to 0.5 times the radius of the through hole, and the width of the unit unevenness may be 0.01 to 0.5 times the height of the through hole. The unit unevenness may be formed in a predetermined pattern with a predetermined height and width, and if necessary, may be formed in an irregular pattern such as wrinkles within the above range.

8 is a schematic view of a cleaning tool according to another embodiment of the present invention. Referring to FIG. 8 , the cleaning tool may further include a fixing part 200 for fixing the cleaning tool, and a handle 300 connected to the fixing part.

The cleaning tool 100 may have a detachable structure from the fixing part 200 so that it can be detached and replaced. Various methods may be applied, such as a sliding method to put in, a press fit method using a tolerance between the fixing part 200 and the cleaning tool 100 .

By allowing the cleaning tool 100 to be separated and replaced from the fixing part 200 , when the scale removal performance deteriorates as the waterproof layer 120 wears, scale removal by replacing only the cleaning tool 100 part It is possible to maintain the performance and improve the maintenance and use convenience of the cleaning tool 100 by setting the cleaning tool 100 having various shapes and sizes according to the type of cleaning object to be replaced and applied.

The handle 300 may be provided in the form of a bar (FIG. 8(a)), and, if necessary, may be provided in the form of a panel in which a through hole of a predetermined size is formed (FIG. 8(b)). In addition, the handle 300 may be formed integrally with the fixing unit 200 , and may have a structure capable of being separated and combined with each other, if necessary.

9 is a schematic view of a cleaning tool according to another embodiment of the present invention. Referring to FIG. 9 , the cleaning tool 100 may be sealed inside the cleaning pad 400 made of a textile fabric.

The washing pad 400 may serve to remove contaminants while rubbing or rubbing applied to washing, that is, tableware. The washing pad 400 may be formed by folding and sewing a single fiber fabric. By folding or overlapping the textile fabric, the edge can be sewn, and in this case, it is preferable to sew except for the cleaning tool input unit 410 .

The textile fabric may include an outer layer including a plurality of pores and an inner layer interposed between the outer layer, and the outer layer may be interconnected by the inner layer to have an integrated structure. Specifically, it may include an outer layer parallel to each other and an inner layer interposed between the outer layer.

The yarns of the inner layer interconnecting the outer layers are irregularly arranged in a loose structure, so that spaces, ie, voids, may be formed between the yarns, and bubbles may be easily generated by the voids. In addition, even though it is woven as a single layer, since the two outer layers have a three-dimensional structure connected by an inner layer, it is possible to provide a cushioning feeling as in the case where the fabric is laminated in three or more layers, thereby improving durability and cleaning power.

The outer layer may have a reticulated structure. In general, since the cleaning pad serves to remove contaminants during washing, contaminants may remain after washing, and thus there is a risk of bacterial propagation. Furthermore, when washing dishes with the washing pad propagated by bacteria, the risk of exposure and infection to bacteria increases, and in particular, it may have a fatal effect on users with low immunity, such as the elderly and children. The outer layer having the mesh-like structure can shorten the drying time of the washing pad, thereby preventing bacterial propagation, and allowing the washing pad to be hygienically managed.

The fiber fabric may be one selected from the group consisting of a polyester yarn, a polypropylene yarn, a polyethylene yarn, a low density polyethylene yarn, a high density polyethylene yarn, and a combination of two or more thereof, but is not limited thereto.

The textile fabric may contain an antibacterial agent. For example, the antimicrobial agent may be appropriately dispersed inside the yarn constituting the textile fabric, appropriately applied to the surface of the yarn, or present in a combination thereof.

The thickness of the textile fabric may be 1 ~ 10mm. If the thickness of the textile fabric is less than 1mm, the cleaning power may be lowered, and if it exceeds 10mm, it may be thicker than necessary to reduce the feeling of use.

The porosity of the textile fabric may be 10 to 50% by volume. If the porosity of the textile fabric is less than 10% by volume, the cleaning power may be reduced, and if it exceeds 50% by volume, the durability of the cleaning pad may be reduced.

The cleaning pad 400 may have an empty space therein, and the cleaning tool 100 may be inserted into the cleaning pad 400 through the cleaning tool input unit 410 . When the cleaning tool 100 is sealed inside the cleaning pad 400 , the cleaning tool 100 can be applied to general purposes such as washing dishes, car washing, and water cleaning as well as removing scale. In addition, since bubbles may be continuously generated by the washing pad 400 , a feeling of use during washing may be improved.

On the other hand, the cleaning tool according to one aspect of the present invention reduces the amount of detergent or bleach or makes it possible to easily remove scale and other contaminants generated on the object to be washed even without substantially using detergent or bleach, so that the use of detergents, etc. It is possible to obtain the effect of preventing environmental pollution and skin diseases caused by exposure to bleach.

The above description of the present invention is for illustration, and those of ordinary skill in the art to which the present invention pertains can understand that it can be easily modified into other specific forms without changing the technical spirit or essential features of the present invention. will be. Therefore, it should be understood that the embodiments described above are illustrative in all respects and not restrictive. For example, each component described as a single type may be implemented in a dispersed form, and likewise components described as distributed may be implemented in a combined form.
