Sink filters and drains can leave food residue during cooking or discarding. Often immersed in water, creating an environment that is prone to microbial growth, it is easy to become dirty and cause serious odors. Cleaning the filter or drain so that it can be kept clean is not only inconvenient, but also takes a lot of time and labor. However, there is no special countermeasure other than the method of replacing the filter screen or the drain pipe, so it becomes a problem.

In order to solve the above problems, US Patent Application No. 14-529388 discloses a two-liquid type system for cleaning pipes after hydrogen peroxide is foamed by hydrolase such as amylase. However, in such a system, the bactericidal bleaching ability of hydrogen peroxide is significantly lower than that of sodium hypochlorite, and therefore, there is a disadvantage that the bactericidal bleaching effect cannot be fully exhibited.

In addition, US Published Patent US2003/0171234 A1 discloses a method of pouring a viscous sodium hypochlorite composition and a foaming agent at the same time, and cleaning the pipeline after foaming. However, in this cleaning method, the sodium hypochlorite and the foaming agent are not easily mixed uniformly, and in the vertically arranged water tank pipes, the foam cannot be retained for a long time and can be discharged immediately, so the ability to maintain cleaning is limited. In addition, in order to obtain the foaming effect, when the sodium hypochlorite composition and acidic hydrogen peroxide are mixed, there is a problem that a large amount of chlorine gas which is harmful to the human body is generated.

Therefore, the current situation is that it is necessary to develop a tool or method that can more effectively clean the sink drain pipe by prolonging the duration of the cleaning effect of the foaming cleaning agent composition. In addition, in the foaming cleaning agent composition, in order to improve the cleaning ability, it is very important to adjust the compounding ratio of the components so as to sufficiently induce the foaming reaction and to suppress the generation of chlorine gas.

The problem to be solved by the invention

In view of the above-mentioned circumstances, the problem to be solved by the present invention is to provide a filter net which is cleaned with foam generated by a drain cleaning agent for foam cleaning, and the cleaning agent flows into the drain pipe slowly, so that the drain pipe can be continuously cleaned. cleaning container.

In addition, the subject to be solved by the present invention is to provide a drain pipe cleaning agent composition which maximizes the cleaning effect of the drain pipe and suppresses the generation of chlorine gas.

In addition, the problem to be solved by the present invention is to provide a set including a drain cleaning agent for foam cleaning and a drain cleaning container for foam cleaning.

In addition, the problem to be solved by the present invention is to provide a method for effectively cleaning a kitchen sink filter net and a drain pipe at the same time by using the cleaning container.

solution to the problem

In order to solve the above-mentioned problems, the present invention provides a cleaning container that can slowly flow a drain pipe cleaning agent for foam cleaning into the drain pipe, and a cleaning container for effectively foaming and cleaning a filter screen and a drain pipe of a kitchen sink using the container. method.

In order to overcome the above-mentioned problems in the prior art, the inventors of the present invention, through intensive research efforts, have developed a device including an inflow port and a discharge port that can slowly flow the cleaning agent for foam cleaning into the filter screen, the drain port, and the drain pipe. Clean the container. The inventors of the present invention surprisingly found that when the cleaning agent for foam cleaning and the cleaning container are used at the same time, the cleaning agent with abundant foam is discharged through the inflow port, so that the filter screen and the drain port can be effectively cleaned, and the hair The foam cleaning agent is slowly discharged through the discharge port, which can foam and clean the drain pipe for a long time, thereby significantly improving the cleaning effect of the filter screen, the drain port and the drain pipe of the kitchen sink, thus completing the present invention.

The present invention provides a drainage pipe cleaning container for foam cleaning, which comprises: a container body having an accommodating space formed inside; an inflow port through which a drainage pipe cleaning agent for foam cleaning flows into the accommodating space; and a container formed in the accommodating space. The container body has at least one outlet for discharging the cleaning agent accommodated in the container body to the drain pipe so that the storage space accommodated in the container body communicates with the drain pipe, compared with the case where the cleaning agent is immediately disposed of to the drain pipe, This discharge port can discharge at a slow speed. The above-mentioned case of immediately disposing the cleaning agent to the drain refers to the case of disposing the cleaning agent directly to the drain or drain without using a cleaning container. The cleaning container may be provided at the drain port for connection with the drain pipe.

The drain pipe cleaning container for foaming cleaning allows the foam generated by the foaming cleaning agent composition to overflow through the inflow port and stay in the drain port and the filter screen. The discharge port of the filter slowly flows out, and the cleaning effect on the drain pipe is continuously maintained, so the cleaning effect on the drain pipe is excellent. Preferably, the drain pipe cleaning container for foam cleaning cleans the drain pipe with the cleaning agent flowing out through the narrow discharge port while cleaning the drain port or the filter screen with the foamed foam.

As an example, in order to use the foam generated by the foaming cleaning agent to clean the drain port and the filter, and to allow the cleaning agent to slowly flow into the drain pipe, the drain pipe cleaning container for foam cleaning may be in the form of a cup including a drain port. In FIG. 1, an example of the drain pipe cleaning container for foam cleaning in the form of a cup is shown.

As an example, the drain pipe cleaning container for foam cleaning may use a container whose diameter gradually decreases from top to bottom. In FIG. 5, the figure which shows the drain pipe cleaning container for foam cleaning which has the above-mentioned characteristics is shown. The diameter of the upper face may be the same or slightly smaller diameter than the drain or screen. In addition, the diameter of the upper face can be a preset diameter, so as to be able to be inserted into the drainage port or the filter screen to form a plug-and-socket combination. In addition, the upper side may further include a clamping table, so as to be able to be clamped on the water outlet along the edge of the upper end. To sum up, since the shape of the container is that the diameter gradually decreases from the top to the bottom, the upper end of the container can be hung on the drain or the filter net, and the lower end can enter the inner side of the filter net.

In addition, the drain pipe cleaning container for foam cleaning may include a concave-convex structure provided with concave-convex grooves at preset intervals, so that the cleaning agent discharged through the inflow port can flow along the outer surface. With the concave-convex structure as described above, even if the container is in close contact with the filter screen or the drain port, the discharged cleaning agent flows down along the concave-convex structure, and the cleaning effect on the filter screen or the drain port can be improved.

In the drainage pipe cleaning container for foam cleaning, the cleaning agent contained in the container space can be discharged at a slower speed than when the cleaning agent is immediately disposed of to the drain pipe. This speed is not particularly limited, but the speed can be It is the speed at which the cleaning agent accommodated in the accommodation space is discharged over 10 to 180 minutes, preferably 20 to 150 minutes, and more preferably 30 to 120 minutes. In this way, by adjusting the discharge speed so that the cleaning agent can be slowly discharged for a long time, the cleaning effect on the drain pipe can be continuously produced, which can be significantly compared with the method of simply pouring the cleaning agent into the drain port to clean the drain pipe. Improve the cleaning effect.

In the present invention, the discharge port of the cleaning container may have a preset diameter so that the cleaning agent can be discharged through the discharge port at a rate of 1-100ml/min, preferably 5-50ml/min, more preferably 7-20ml/min.

In the drainage pipe cleaning container, the preset diameter of the discharge opening can be 0.1-10 mm, preferably 0.3-5 mm, and more preferably 0.5-3 mm. When the diameter of the discharge port is less than 0.1 mm, the cleaning agent flows out too slowly, resulting in prolonged cleaning time, and when it exceeds 10 mm, the cleaning performance improvement effect expected by the present invention is weak due to the too fast outflow.

In addition, according to a preferred embodiment of the present invention, the cleaning container may include discharge ports with preset diameters and numbers, so that the cleaning agent can be discharged through the discharge ports for 10-180 minutes, preferably for 20-150 minutes, and more preferably for 30-120 minutes. minute. In particular, when the discharge time of the cleaning agent for foam cleaning is less than 30 minutes, the average killing rate of microorganisms is low, and when it exceeds 120 minutes, the enhancement effect of its bactericidal ability is weak, therefore, the discharge time is preferably controlled at 30 minutes. ~120 minutes.

In the drainage pipe cleaning container, the preset diameter of the discharge opening can be 0.1-10 mm, preferably 0.3-5 mm, more preferably 0.5-3 mm, and most preferably 1-2.5 mm. In addition, the number of discharge ports may be 1 to 8, preferably 1 to 6, and more preferably 2 to 5. Preferably, when 2 to 5 discharge ports are formed with a diameter of 1 to 2.5 mm in the drainage pipe cleaning container of the present invention, the cleaning agent can be discharged through the discharge port for 30 minutes to 120 minutes, so the drainage pipe cleaning effect can be exerted. to the best. More preferably, using the cleaning agent of the present invention to clean the drain pipe for more than 50 minutes can fully exert its cleaning effect. usage time.

In addition, the present invention provides a drainpipe cleaning container for foam cleaning, comprising: a container body having a accommodating space formed inside; an inflow port through which a drainpipe cleaning agent for foam cleaning flows into the accommodating space; and a container body formed in the container body , so as to connect the accommodating space contained in the container body with the drain pipe, at least one outlet for discharging the cleaning agent contained in the accommodating space to the drain pipe; The member can be discharged at a slower rate than when the cleaning agent is immediately disposed of in the drain.

In this drain cleaning container for foam cleaning, a mesh member through which the drain cleaning agent passes can be formed in the inflow port. Thereby, the first agent and the second agent of the cleaning agent flowing in through the mesh member of the inflow port can be uniformly diffused downward in the cleaning container and mixed uniformly. In addition, the foam of the foaming cleaning agent is discharged to the outside through the mesh member formed in the inflow port, thereby forming denser foam, so that the cleaning effect can be significantly improved.

In the present invention, the mesh member may have a mesh shape. Alternatively, a member made of a non-woven fabric material with uneven intervals may be used in place of the mesh-like mesh members at predetermined intervals, but the present invention is not limited to this.

Preferably, the pore size of the mesh member may be 100-10000 μm, preferably 300-4000 μm, more preferably 400-2000 μm, and most preferably 400-900 μm. When the pore size of the mesh member is less than 100 μm, it is not suitable because the cleaning composition does not easily pass through, and when it exceeds 10000 μm, the effect of homogenizing the cleaning mixture and densifying the discharged foam is reduced.

In the present invention, the mesh member may be made of metal wire, and the metal wire may include any one or more materials selected from the group consisting of stainless steel, glass fiber, polyethylene (PE), and the like. In addition, as a mesh member, a square mesh member can be formed by perpendicularly intersecting the vertical and horizontal lines of the metal wire. From the viewpoint of the present invention, when the cleaning composition flows through the mesh member as described above, the effect of homogenizing the cleaning agent flowing in and the densifying effect of the foaming foam discharged through the inflow port are most excellent.

As an example, in order to use the foam generated by the foaming cleaning agent to clean the drain port and the filter screen, and make the cleaning agent slowly flow into the drain pipe, the drain pipe cleaning container for foam cleaning includes a drain port, and can be a flow In the cup form in which the mesh member is formed at the inlet, FIG. 12 shows an example of the drain pipe cleaning container for foam washing in the cup form.

In the present invention, HDPE (high density polyethylene, high density polyethylene), LDPE (low density polyethylene, low density polyethylene), PET (polyterephthalic acid) can be used as the material of the drain pipe cleaning container for foam cleaning. Glycol ester, polyethylene terephthalate), PP (polypropylene, polypropylene), PE (polyethylene, polyethylene), PC (polycarbonate, polycarbonate), PS (polystyrene, polystyrene) or ABS (acrylonitrile-butanediol) ethylene-styrene copolymer, acrylonitrile butadiene styrene) and other commonly used plastic materials, paper, glass or metal materials.

In the present invention, as the foam cleaning composition for drain pipe cleaning, any conventional cleaning composition such as a composition containing a bleaching agent for cleaning a filter screen, a drain port or a drain pipe can be used, and there is no particular limit.

Preferably, the present invention provides a drainpipe cleaning agent for foam cleaning comprising a first composition and a second composition respectively, wherein the first composition contains a chlorine-based cleaning agent component, preferably hypochlorite ; The second composition comprises a blowing agent, preferably hydrogen peroxide. More specifically, the drainpipe cleaning agent for foam cleaning may contain a first composition containing a chlorine-based cleaning agent component and a second composition containing a foaming agent, respectively. The first dose composition or the second dose composition may contain an anionic surfactant, a nonionic surfactant, a mixture of the two, or the like.

In the present invention, the first composition and the second composition may be mixed and used in the storage space of the drain pipe cleaning container for foam cleaning of the present invention described below. In addition, when using, the weight ratio of the first composition and the second composition (the first composition: the second composition) can be 10:1 to 1:10, preferably 5:1 to 1:1. 5. It is more preferably 3:1 to 1:3, and within this weight ratio range, the foaming ability and the cleaning ability are the most excellent.

In the present invention, as a chlorine-based cleaning agent component and a foaming agent, a reaction between hypochlorite and hydrogen peroxide is preferable, and a reaction in which oxygen is generated and foamed as shown in the following reaction formula 1 can be used. In addition to this, various methods can be used to carry out the foaming reaction, for example, the reaction of sodium carbonate, sodium bicarbonate, etc. with an organic acid (citric acid, lactic acid, etc.) or an inorganic acid (sulfamic acid, etc.), and Similar effects can be obtained by blending surfactants or bactericides. However, in the present invention, hypochlorite and hydrogen peroxide can be reacted as main components to produce a foaming cleaning effect, and in this case, the cleaning effect is the most excellent compared with other foaming cleaning methods.

Reaction formula 1: NaOCl + H2O2 NaCl + H2O + 1/2 O2

In the present invention, the first agent may contain a chlorine-based cleaning agent as the main component, preferably hypochlorite, which has excellent sterilization and floating effects, and has a fast decomposition rate after being diluted, and has less residual and oral toxicity. Therefore, , can be effectively used in the sterilization and disinfection of food and tableware.

As the hypochlorite used as an active ingredient for sterilization or disinfection, one or more selected from the group consisting of sodium hypochlorite (NaOCl), potassium hypochlorite, calcium hypochlorite, magnesium hypochlorite, and the like can be used. Sodium hypochlorite can be preferably used as the hypochlorite.

The chlorine-based cleaning agent component, preferably the hypochlorite, may be used in an amount of 0.1 to 30% by weight, preferably 5 to 27% by weight, and more preferably 15 to 25% by weight, based on the total weight of the first composition. When the usage amount of the chlorine-based cleaning agent component is less than 0.1% by weight, the sterilization or disinfection function is weak, and when it exceeds 30% by weight, the compatibility with the surfactant is poor, and the stability of the chloric acid ion itself is also poor. unfavorable.

In the present invention, in order to improve the foaming cleaning effect of the cleaning composition, it can be 1:1 to 10:1, preferably 1.25:1 to 9:1, more preferably 2:1 to 7:1, most preferably Hypochlorite and hydrogen peroxide are contained in an equivalent ratio (hypochlorite:hydrogen peroxide) of 3:1 to 5:1. The cleaning agent composition in this equivalence ratio range has the most excellent foaming ability and cleaning ability.

In addition, the present invention provides a drain cleaning agent composition comprising a first agent containing a chlorine-based cleaning agent component, a second agent containing a foaming agent, and a pH adjuster, preferably a two-component foaming agent for drain cleaning cleaning composition. Preferably, hypochlorite or the like can be used as the chlorine-based cleaning agent, and hydrogen peroxide or the like can be used as the foaming agent. When a pH adjuster is added in order to keep the pH value at 9 or more when mixing a chlorine-based cleaning agent component and a foaming agent, the generation of chlorine gas harmful to the human body can be significantly suppressed.

More specifically, since the drain cleaning agent composition of this invention contains a pH adjuster, the pH of the composition containing the chlorine type cleaning agent component of the 1st agent, preferably the composition containing sodium hypochlorite can be maintained at 12 or more. In addition, after mixing the second agent of the acidic foaming agent composition of the present invention with the first agent, the pH of the mixture can still be maintained above 9, and a large amount of chlorine gas will not be generated. Therefore, the filter screen of the kitchen sink can be safely cleaned And the drain pipe for foam cleaning.

In the present invention, in the process of mixing the first agent with sodium hypochlorite as the main component and the second agent with acidic hydrogen peroxide as the main component, a large amount of harmful chlorine gas will be generated. Because chlorine gas is very dangerous to the human body, therefore , the formulation of the first and second doses is carefully designed to produce the least amount of chlorine gas. In particular, when the first agent and the second agent are mixed, the generation amount of chlorine gas is also preferably minimized. Sodium hypochlorite generates a large amount of chlorine gas when the pH is less than 9. Therefore, it is very dangerous to the human body. In addition, when the first dose and the second dose are mixed, chlorine gas is also generated rapidly in an instant. Therefore, in order to prevent the above situation It is very important to adjust the pH of the mixture.

In the present invention, in the process of mixing the first agent and the second agent, a part of the sodium hypochlorite contained in the first agent reacts with hydrogen peroxide and is converted into sodium chloride, water, and oxygen. In order to suppress the rapid decomposition of the remaining sodium hypochlorite after the reaction to generate a large amount of chlorine gas, the pH value of the mixture of the first agent and the second agent is preferably 9-14, more preferably 11-14, which is safer.

Since the drain pipe cleaning agent composition of this invention contains a pH adjuster, when a 1st agent and a 2nd agent are mixed, the generation|occurence|production of chlorine gas can be suppressed remarkably. The amount of chlorine gas generated when using the drain cleaning composition is less than 300 ppm, preferably less than 100 ppm, more preferably less than 50 ppm. For reference, the toxic concentration (LC50) of chlorine gas is 293ppm according to the standards of the Chemical Safety Data Sheet (MSDS) provided by the safety and health agency. When using the drain pipe cleaning agent composition in this invention, compared with this toxic concentration (LC50), since the generation amount of chlorine gas can be suppressed remarkably, it is very excellent in safety to a human body.

In the present invention, a pH adjuster can be used in the drain cleaning agent composition so as to keep the pH above 9 after mixing the first agent and the second agent, thereby minimizing the generation of chlorine gas. As the pH adjuster, any one or more selected from the group consisting of sodium hydroxide (NaOH), potassium hydroxide (KOH), sodium silicate (Na3SiO3, Na4SiO4), and sodium carbonate (Na2CO3) can be used, and preferably Sodium hydroxide can be used.

When the content of the pH adjusting agent is less than the equivalent ratio of 1.1:1 (pH adjusting agent: the equivalent of the total amount of hydrogen ions of the acidic substance contained in the second agent), since the pH value after mixing is less than 9, the chlorine gas Production will increase dramatically. When the pH adjusting agent is contained in an equivalent ratio of more than 10:1 (pH adjusting agent: the equivalent of the total amount of hydrogen ions of the acidic substance contained in the second agent), the reactivity of the chlorine-based cleaning agent component and the foaming agent may decrease. reduce.
