Description

Sterilizing and cleaning device for water treatment equipment {STERILIZING APPARATUS FOR WATER TREATMENT APPARATUS}

The present invention relates to a sterilization washing apparatus for a water treatment apparatus capable of sterilizing and / or cleaning a storage tank of a water treatment apparatus and a flow path connected thereto, and a sterilization washing method of a water treatment apparatus. And / or sterilizing wash water comprising a cleaning material (hereinafter, the term 'sterilizing wash water' shall mean water including sterilizing material and / or cleaning material generated by an electrode to which power is applied). Sterilizing and cleaning apparatus for sterilizing and / or cleaning the flow path, the storage tank or the water discharge coke inside the water treatment device by generating water and introducing sterilized clean water into the flow path, the storage tank or the water discharge cock provided in the water treatment device. And to a method for sterilizing and cleaning a water treatment device.

On the other hand, the water treatment device (water treatment device) can be used for various purposes, such as industrial or household (including commercial use), such as to treat waste water or water, or to produce ultrapure water, the present invention is particularly used for drinking water treatment equipment and sterilization thereof It relates to a cleaning method. As such, the water treatment device for drinking is generally referred to as a water purifier in a narrow sense because it receives raw water (constant water) and then filters and generates purified water for drinking. The water purifier is configured to provide the user with purified water at room temperature filtered by the filter unit by receiving raw water (constant water), and may be configured to provide hot water and / or cold water to the user by heating / cooling the purified water at room temperature. do.

In addition, not only purified water but also functional water for supplying various functional water, such as ionized water, carbonated water, and oxygen water, may be used for drinking water treatment equipment. In addition, there is a water heater, a cold water machine, an ice maker, etc., which heat or cool water supplied from a water supply means such as a water tank or generate ice. In the present specification, the water treatment device is used as a generic term for a water purifier, a functional water machine, a water heater, a cold water machine, an ice maker, and the like having a combination of these functions. However, the water purifier may be taken as an example for convenience of description, but the water purifier should be understood as an example of the water treatment device according to the present invention.

In general, the water purifier is classified into a hollow fiber membrane method and a reverse osmosis membrane method according to the water purification method.

Of these, the reverse osmosis membrane type water purifier is known to be superior to other water purification methods developed so far in removing contaminants.

The reverse osmosis membrane type water purifier receives raw water from tap water and the like and removes dust, debris and various suspended substances through a fine filter of about 5 microns, and a carcinogen (THM) by using an activated carbon adsorption method. It consists of a free carbon filter that removes harmful chemicals such as synthetic detergents and insecticides and residual chlorine, and a reverse osmosis membrane of 0.0001 micron to filter heavy metals such as lead and arsenic, as well as sodium and various pathogens. The reverse osmosis membrane filter (RO membrane filter) to be discharged through, and the filter unit including a post carbon filter for removing the unpleasant taste and smell, pigments, etc. contained in the water passing through the reverse osmosis membrane filter.

In addition, a hollow fiber membrane type water purifier uses a hollow fiber membrane filter (ultrafiltration filter, UF) instead of the said reverse osmosis membrane filter. The hollow fiber membrane filter is a porous filter having pores of several tens to hundreds of nanometers (nm) in size, and removes contaminants in water through the myriad of micropores distributed on the membrane surface.

However, such a water purifier has a problem that microorganisms or bacteria remaining in the pores of the post carbon filter may be introduced into the storage tank so that the microorganisms may re-grow in the storage tank. In addition, bacteria or microorganisms may penetrate and purify the purified water stored in the storage tank from outside, and scale may occur on the inner wall of the storage tank.

Thus, in order to sterilize bacteria or microorganisms propagated in the storage tank, a technique for sterilizing the storage tank by adding a separate sterilizing agent to the storage tank from the outside has been proposed.

However, such a sterilizing drug supply method has a problem that the user or the water purifier manager is performed through a separate sterilizing chemical supply operation, so that the sterilizing operation is cumbersome and the sterilization management is inefficient. That is, when the sterilizing agent is added, there is a problem that it is very cumbersome because the automatic injection of the sterilizing drug is impossible or automatic filling is required.

In addition, when the sterilizing agent is added, the concentration of the sterilizing agent may be higher than necessary in some cases, and since there is a difference between the addition and the small amount of the sterilizing agent according to the user or the administrator, the sterilizing agent remains in the water purifier after the cleaning operation. The problem is that it can be done. Therefore, a plurality of rinsing after the cleaning operation is essential, and if the rinsing operation is not perfect, not only harmful to the human body but also increase the complaints due to the smell of the drug.

In addition, since the water purifier manager needs to perform a sterilization drug supply operation, a cost for sterilization treatment of the water purifier is generated, and the user may feel a burden on the service cost.

In particular, since the water purifier itself is not sterilized and cleaned by the service organizer, it is inconvenient to exist, and thus the reliability of the water purifier is deteriorated.

In addition, the conditions under which the sterilizing agent melts or elutes are different depending on the water purifier operating conditions (eg, raw water pressure, flow rate, etc.). As an example, when the flow rate is low, the sterilization concentration may be relatively high. On the contrary, since the sterilization concentration is low when the flow rate is high, there are many difficulties in controlling sterilization. As a result, when the concentration of the sterilizing agent is high, odor may occur.

In addition, the sterilization material generated by the sterilization chemicals are mainly OCl ^- low pH or very high odor, so the odor is generated a lot, sterilization performance is only about 1/70 compared to HOCl, so a large amount for sterilization of the same tank capacity There is a problem that requires a sterilizing material.

On the other hand, Patent Application No. 2009-0047174 filed by the present applicant discloses a washing apparatus for a water treatment device that can automatically clean the water purification tank using a sterilizing drug and a cleaning method thereof.

However, in the case of the patent application of the present applicant, the neutralization process is required to neutralize the drug due to the toxicity of the sterilizing drug in the same way as the manual sterilization using the sterilizing drug, and therefore, the sterilization cleaning and neutralization of the water treatment device, In addition, there is a disadvantage in that a long time is required for the subsequent rinsing operation. In addition, the patent application has a difficulty in that a lot of manual work is required for sterilization cleaning in that the sterilizing agent and the neutralizing agent should be directly supplied.

Accordingly, there is a need for a method of sterilizing and cleaning different from the conventional method.

[First Embodiment of Sterilization Cleaner]

First, referring to FIGS. 1 to 4, a sterilizing and cleaning apparatus for a water treatment device according to a first embodiment of the present invention will be described.

1 to 4, the sterilization cleaning apparatus 100 according to the first embodiment of the present invention includes an electrode sterilization module 100a and a connection member 190.

The electrode sterilization module 100a generates a sterilizing wash water containing sterilizing material or cleaning material by applying power to the electrode, and the connection member 190 of the electrode sterilizing module 100a and the water treatment device 200. The flow path is connected and supplied to the water treatment device 200.

The connection member 190 may include one or more connection pipes 180 connected to the water outlet 260 of the water treatment device 200, and filter flow path tubes L1, L2, L3, and L4 of the water treatment device 200. It is provided with a sterile water supply pipe 191 connected to the tank inlet flow path tube (L5) or the storage tank 220. On the other hand, in the present specification (including the claims), the filter portion flow path pipe (L1, L2, L3, L4) is used as a term referring to the flow path pipe flowing into each filter (210, 220, 230, 240), usually Raw water (constant) flows through the first flow path tube L1, and purified water filtered by the sediment filter 210 flows through the second flow path tube L2. In addition, in this specification, the filter part flow path pipes L1, L2, L3, L4 and the tank inlet flow path pipe L5 will be collectively referred to as a flow path pipe.

In this case, the connection pipe 180 is detachably connected to at least one of the water extraction cocks 261 and 262 and the drain pipes 263 and 264 constituting the water extraction unit 260 of the water treatment device 200. The water supply pipe 191 is detachably connected to the filter part flow path tubes L1, L2, L3, and L4, the tank inlet flow path tube L5, or the storage tank 220 of the water treatment device 200.

For example, referring to FIGS. 2 to 4, when the storage tank 220 includes the purified water tank 230, the cold water tank 240, and the hot water tank 250, the purified water tank 230 and the cold water tank ( The first connection pipe 181 may be connected between the cold / purified water discharge coke (261) and the inlet port 111 to discharge the water contained in the 240, the hot water discharge coke to discharge the water contained in the hot water tank (240) The second connector 182 may be connected between the 262 and the inlet 112. In addition, the third connection pipe 183 may be connected between the cold / purified water drain pipe 263 and the inlet 113 for draining the water contained in the purified water tank 230 and the cold water tank 240, the hot water tank 250 The fourth connecting pipe 184 may be connected between the hot water drain pipe 264 and the inlet 114 for draining the water contained in the). The number of the connection pipe 180 or the type of flow path to which the connection pipe 180 is connected may vary depending on the specific configuration of the water treatment device 200. For example, when there is no hot water tank 240 or when the sterilization and cleaning of the hot water tank 240 is not performed, since the hot water discharge coke 262 and the hot water drain pipe 264 are not provided, the second and fourth connection pipes are not provided. 182 and 184 may not be connected, and when a flow path of the water treatment device 200 is added, an additional connector 180 may be installed.

In addition, the sterilization water supply pipe 191 is a filter unit flow path pipe (L1, L2, L3, L4) for sterilizing and cleaning the storage tank 220 and the flow path (including the water extraction cock) connected thereto of the water treatment device 200 ), May be connected to the tank inlet flow path (L5) or the storage tank 220.

On the other hand, as shown in Figures 2 to 4, one end of the connector 180 is connected to the water outlet 260 of the water treatment device 200, the other end of the connector 180 is the electrode sterilization module (100a) It is also possible to be connected to the inlets (111, 112, 113, 114) of, but as shown in Figure 17 to 20, etc., the other end of the connection pipe 180 is not connected to the electrode sterilization module (100a) water treatment equipment The sterilizing wash water discharged from the water outlet 260 of the 200 may be configured to be disposed in the drain so as to be discharged through a drain hole (including a temporary storage container for containing sterilizing wash water) D1, such as a sink. In addition, without connecting the connection pipe 180 to the water treatment unit 200 to the water extraction unit 260, it is also possible to discharge the sterilized washing water directly from the water extraction unit 260 using a storage container.

In addition, the electrode sterilization module 100a may include a housing 101, an electrode unit 170 and a pump 140 provided inside the housing 101, and optionally, a flow path switching unit 110. ), The concentration sensor 120, the drain flow path switching valve 160 and the control unit (C) may be further provided.

The electrode unit 170 is sterilized wash water containing sterilizing material or cleaning material by applying power to the electrode therein (in the present specification, 'sterilizing wash water' is water that can perform at least one of sterilization and cleaning functions) Will be created).

As an example, the electrode unit 170 is electrolyzed (in this specification, the term electrolysis will be described as including 'redox reaction') by introducing the oxidizing mixture (MO: Mixed Oxidant) It can be configured to generate a sterilized washing water containing a material having a sterilizing function and / or cleaning function.

The electrode unit 170 sterilizes or extinguishes microorganisms or bacteria remaining in the water by passing water between electrodes having different polarities. In general, the sterilization of purified water by electrolysis involves direct oxidation reactions that directly oxidize microorganisms at the anode, and various oxidizing mixtures (MO: Mixed Oxidants) that may occur at the anode, such as residual chlorine, ozone, OH radicals and oxygen. Indirect oxidation reaction in which radicals oxidize microorganisms is performed in a complex manner.

And, as shown in Figure 1, in the case of an embodiment of the present invention to enable the generation of sterilization material without adding a separate electrolyte (hereinafter described in the concept including both salt, chloride) It is preferable to coat ruthenium (Ru) on the electrode body of the electrode. Ruthenium (Ru) is Cl ^- as a catalyst, which lowers the potential difference when the reduction in the Cl ₂ and the resulting in the water by the ruthenium Cl ₂ was immediately dissolved in the water is the HOCl (residual chlorine). Flow rate and voltage conditions can be set to maximize the activity of the ruthenium (Ru) catalyst.

In addition, in the case of the electrode unit 170 according to an embodiment of the present invention, ruthenium (Ru) is coated on the electrode body of the anode electrode (more precisely, after ruthenium is coated, the ruthenium-coated electrode is heated and oxidized by heating to a high temperature. Since ruthenium oxide (RuOx) is changed, it is ruthenium oxide that remains on the surface of the electrode, but since the material coated at the beginning of the electrode is ruthenium, the present specification includes a state in which ruthenium is coated. I will use it). Therefore, it is efficient to set the maximum voltage to 30 volts, more preferably 24 volts, and the power to be within 12 watts in order to prevent ruthenium (Ru) catalyst activity and coating damage.

In addition, when ruthenium (Ru) is used for the electrode body, the life of the electrode may be shortened, but the low life of the electrode can be prevented because the electrode life is shortened. In order to further extend the life of the ruthenium (Ru) coated electrode, it is preferable to further reduce the current, and for this purpose, it is preferable to form the cathode electrode, which is a counter electrode, using only a titanium (Ti) electrode without a separate coating.

That is, in the case of using titanium (Ti) as the cathode electrode, the effect of lowering the current at the same voltage can be achieved. When the current is lowered, the power is also reduced, which leads to an increase in the lifetime of the cathode electrode and the anode electrode. Will be.

As described above, according to the electrode unit 170 according to an embodiment of the present invention, a ruthenium (Ru) coated electrode is used as the anode electrode, the cathode electrode is used as titanium (Ti), and the gap between the electrodes is controlled. By doing so, it is possible to obtain an advantageous effect of producing a sterilizing substance of a desired concentration without additional chloride (electrolyte) addition and at low current or low power. However, the material of the electrode provided in the electrode unit 170 according to the present invention is not limited to the above materials, various modifications may be made according to the embodiment.

Meanwhile, the electrode unit 170 according to an embodiment of the present invention preferably includes one anode electrode and two cathode electrodes disposed on both sides thereof.

Of course, two anode electrodes and one cathode electrode may be used, or both the anode electrode and the cathode electrode may be used one by one, but one anode electrode and one cathode electrode can be used to minimize the current value while realizing the concentration of the sterilizing material. It is more preferable that two sheets are used to arrange the (-) electrode, the (+) electrode, and the (-) electrode.

As such, in the case of the electrode unit 170 according to an embodiment of the present invention, low current and low power can be driven. For example, the maximum current can be driven at 0.5 A or less, preferably 0.35 A or less. In the case of the maximum voltage, it can be driven at 50V or less, preferably 24V or less. Of course, the power consumption of the electrode unit 170 can also be operated within 12W.

On the other hand, the sterilized washing water (electrolyzed sterilized water) obtained by using an electrode applied with power, the form of chlorine in the water varies depending on the pH, the sterilization power is very different according to the pH, strong acidic electrolyzed water, It may be classified into various forms such as weakly acidic electrolyzed water, strongly alkaline electrolyzed water, and electrolytic sodium hypochlorite water.

As described above, in order to generate various sterilizing washing water (electrolytic sterilizing water), the material and the thickness of the electrode, the size of the applied power (voltage or current), whether electrolyte or salt (including chloride) is added, and the electrolyte or The type of salt (including chloride) may be configured differently, and if it is possible to generate sterilized washing water (electrolytic sterilization water) through the electrode, all of them are included in the scope of the electrode unit 170 according to the present invention. .

That is, as will be described later, even when generating the sterilized wash water by using the electrolyte or salt (including chloride) supplied from the electrolyte supply unit 130 will all be said to correspond to the electrode unit 170 according to the present invention. .

In addition, the pump 140 applies a pressing force to supply the sterilizing clean water generated by the electrode unit 170 to the flow path of the water treatment device 200. The water introduced into the sterilizing and cleaning device 100 through the pump 140 is changed to sterilizing and washing water, and the flow path of the water treatment device 200 through the sterilizing water supply pipe 191, for example, a filter flow path pipe L1, L2, L3, L4), the tank can be supplied to the flow path pipe (L5) or the storage tank (220).

Meanwhile, although the pump 140 is illustrated as being disposed between the drain flow path switching valve 160 and the concentration sensor 120 in FIGS. 1 to 4, the position of the pump 140 can be supplied to the water treatment device by pressurizing the water. Is not particularly limited, and may be provided at the rear end of the electrode unit 170 as an example, or may be installed between the drain flow path switching valve 160 and the electrode unit 170.

In addition, the flow path switching unit 110 may be configured to sequentially open some of the flow paths in communication with one or more connecting pipes 180 connected to the water outlet 260 of the water treatment device 200. .

The flow path switching unit 110 sequentially opens a plurality of inlets 111, 112, 113, 114 one by one and blocks the other inlets, or opens a plurality of inlets sequentially and opens the remaining inlets in a closed state. It can be configured to.

For example, although the first inlet 111 to which the first connector 181 is connected and the second inlet 112 to which the second connector 182 is connected may be sequentially opened, the cold water tank 240 and The first inlet 111 and the third inlet 113 connected thereto are simultaneously opened to open the flow paths of the connected first connector 181 and the third connector 183 at the same time, and the remaining inlets 112 and 114 are simultaneously opened. And then, may be configured to simultaneously open the second inlet 112 and the fourth inlet 114 and block the remaining inlets 111 and 113.

As such, the flow path switching unit 110 sequentially opens some of the flow paths so that the storage tank 220 of the water treatment device 200 corresponding to the open inlet and the flow path connected thereto may be sequentially sterilized and cleaned. The flow path switching means 110 may use a plurality of solenoid valves, such as a disk valve may be used using a variety of known valves or opening and closing means.

In addition, the concentration sensor 120 detects the concentration of the sterilizing material or cleaning material contained in the water flowing into the electrode unit 170. The concentration sensor 120 may be configured as a sensor for measuring the ion concentration, but is not limited thereto if it can detect the concentration of the sterilizing material or cleaning material. In addition, if the concentration of the sterilizing material or cleaning material can be detected, the installation position of the concentration sensor 120 is not particularly limited.

In addition, the outlet flow path switching valve 160 is to switch the flow path to the drain port 161 in order to drain the water flowing into the electrode sterilization module (100a) to the outside. That is, as shown in Figure 1, the outlet flow path switching valve 160 is a flow path for sending the water introduced through the inlet (111, 112, 113, 114) through the electrode unit 170 to the outlet (171) side The flow path is switched between flow paths discharged through the drain pipe 195 connected to the drain port 161. The outlet flow path switching valve 160 discharges the sterilizing clean water to the outside after the sterilization and cleaning operation of the water treatment device 200 is completed, or when the rinsing water is discharged to the outside, the flow path is switched to the outlet port 171.

On the other hand, as shown in Figure 1, the flow path switching means 110, the concentration sensor 120, the pump 140, the drain flow path switching valve 160 and the control unit for controlling the driving of the electrode 170 C) can be installed. The control unit C drives the pump 140 and the electrode unit 170 at the beginning of the sterilization cleaning operation, and opens and closes the flow path of the flow path switching unit 110 so as to sequentially sterilize and clean the various flow paths of the water treatment device 200. When the concentration detected by the concentration sensor 120 is greater than or equal to the set value, the driving of the pump 140 and the electrode unit 170 is stopped.

In addition, the controller C switches the flow path of the drain flow path switching valve 160 at the completion of the sterilization cleaning operation and drives only the pump 140 in a state in which the electrode part 170 is not driven, thereby sterilizing and cleaning through the drain hole 161. The driving of the drain flow path switching valve 160, the pump 140, and the electrode unit 170 is discharged to discharge the water to the outside.

Meanwhile, the electrode sterilization module 100a according to the present invention further includes a display unit D displaying an operation state of the electrode sterilization module 100a and an operation unit B for manipulating the operation of the electrode sterilization module 100a. It may be included as, the display content and the operation content can be variously modified, changed.

As an example, the operation unit (B) may be provided with various selection buttons, such as start button, sterilization stop button, inlet selection button, the display unit (D) sterilization state, standby state, rinsing state, completion state, error state The light may be configured to be displayed by lighting or an alarm.

Next, as an example of the water treatment device 200 in which the sterilizing and cleaning device 100 shown in FIG. 1 may be used, the water purifier 200 shown in FIGS. 2 to 4 will be described as an example.

As shown in FIGS. 2 to 4, the conventional water purifier 200 includes a filter unit 210, a storage tank 220, and a water extraction unit 260.

The filter unit 210 is used to sequentially filter and purify raw water, and includes a sediment filter 211, a pre carbon filter 212, a reverse osmosis membrane filter 213 (or a hollow fiber membrane (ultrafiltration) filter) and Although the post carbon filter 214 may be included, the type, number and order of the filters may be changed according to the filtration method of the water treatment device (purifier) or the filtration performance required for the water treatment device (purifier). For example, a hollow fiber membrane filter may be provided instead of the reverse osmosis membrane filter 213. The hollow fiber membrane filter is a pore filter having pores of several tens to hundreds of nanometers (nm) in size, and removes contaminants in water through a myriad of micropores distributed on the membrane surface.

Here, each of the filters 211, 212, 213, and 214 includes a filter case incorporating a filter element and an outer case accommodating the filter case, wherein raw water obtained into the outer case is a filter element inside the filter case. It may be made of a cartridge structure that is filtered by the water is discharged to the outside of the outer case.

However, in the present invention, as described above, each filter 211, 212, 213, and 214 of the filter unit 210 is not particularly limited to an independent cartridge, and is a composite filter having a function of two or more filters. It may be configured. For example, the sediment filter 211 and the pre carbon filter 212 may be configured as a single pretreatment composite filter.

The sediment filter 211 receives raw water from the raw water supply unit and serves to adsorb and remove a relatively large particulate suspended matter, sand, and the like contained in the raw water. Here, a raw water shut-off valve (V) may be provided at the front end of the sediment filter 211 to selectively block the raw water supplied from the raw water supply unit, if the raw water shut-off valve (V) can block the supply of raw water The installation position of the raw water shutoff valve (V) is not limited thereto.

In addition, the pre-carbon filter 212 is supplied to the water passed through the sediment filter 211 through the adsorption method of activated carbon, such as volatile organic compounds, carcinogens, synthetic detergents, pesticides, etc. It functions to remove substances and residual chlorine (eg HOCl or ClO) components.

In addition, the reverse osmosis membrane filter 213 receives water filtered by the pre-carbon filter 212 to remove fine organic / inorganic substances such as heavy metals and other metal ions and bacteria contained in the water through the membrane having fine pores. The reverse osmosis membrane filter 213 is connected with a drain pipe (DL) for discharging living water generated during filtration of raw water, that is, waste water (commonly known as "concentrated water" in the art).

In addition, the post carbon filter 214 passes through the reverse osmosis membrane filter 213 to adsorb and remove unpleasant tastes, odors, and pigments of the filtered water. The purified water filtered through the post carbon filter 214 is purified through a water purification line. The storage tank 220 is accommodated.

Meanwhile, since the reverse osmosis membrane filter 213 purifies water through the membrane having fine pores, the filter unit 210 may include a pressure pump 215 capable of supplying water to the reverse osmosis membrane filter 213 as a pumping pressure. It may be.

The filter unit 210 is connected to the flow path pipe (L1, L2, L3, L4, L5), the last filter 214 and the storage tank 220 of the filter unit 210 is the tank inlet flow path (L5) Connected through. On the other hand, other members such as sensors and valves may be provided between the tank inlet flow path L5 and the storage tank 220, but even if other members are installed, the last filter 214 of the filter unit 210 and The entire flow path pipe connecting the storage tank 220 will be referred to as a tank inlet flow path tube (L5).

On the other hand, the storage tank 220 passes through the filter unit 210 and stores the purified purified water and discharges the purified water through the water discharge coke (261, 262).

Specifically, the storage tank 220 is a bar for storing the purified water passed through the filter unit 210, the purified water tank 230 for storing the purified water at room temperature state, the cold water tank 240 for cooling and storing the purified water and It may be configured to include at least a portion of the hot water tank 250 for heating and storing the purified water. At this time, the purified water tank 230 and the cold water tank 240 may be installed separately, but may be installed separately in one space through a partition (separator) that can distribute water.

On the other hand, as the water extraction unit 260 for supplying the water contained in the storage tank 220 to the user, the water extraction cock (261, 262) may be provided. At this time, the cold / water discharge coke 261 may be configured to supply purified water or cold water to the user by the user's selection, the hot water discharge coke 262 may be configured to supply hot water to the user. In FIGS. 2 to 4, the purified water and cold water are supplied to the user through one cold / water discharge coke 261. However, separate discharge cokes for supplying purified water and cold water may be installed.

In addition, drain pipes 263 and 264 may be provided as the water outlet 260 connected to the storage tank 220. The drain pipes 263 and 264 are used to empty the storage tank 220 when the storage tank 220 is washed, sterilized and washed with water, and rinsed water is discharged. At this time, the cold / purified water drain pipe 263 is connected to the cold water tank 240 to drain the purified water and cold water, the hot water drain pipe 264 is connected to the hot water tank 250 to drain the hot water.

On the other hand, the process of connecting the sterilization cleaning device 100 to the water treatment device 200 shown in Figures 2 to 4 is connected to the connection pipe 180 and the sterilizing water supply pipe 191 of the sterilization cleaning device 100 water treatment device ( 200).

Specifically, as shown in FIGS. 2 to 4, the cold / water discharge coke 261 and the first inlet 111 are connected to each other through the first connection pipe 181, and the second connection pipe 182 is connected to the cold / water discharge coke 261. Through the hot water outlet cock 262 and the second inlet 112 is connected. In addition, the cold / water drain pipe 263 and the third inlet 113 is connected through the third connector 183, and the hot water drain pipe 264 and the fourth inlet (4) through the fourth connector (184). 114).

And, as shown in Figure 2, through the sterilizing water supply pipe 191 is connected to the storage tank 220 (or purified water tank 230) and the outlet 171. Alternatively, as shown in FIG. 3, the sterilizing water supply pipe 191 may be connected to the tank inlet flow path tube L5 through a connector 265 or the like.

In addition, as shown in FIG. 4, all or part of the filters provided in the filter unit 210 are removed, and the filter unit flow pipes L1, L2, L3, L4 are connected to tubing and connectors C1. After connecting to each other by, C2, C3, C4, it is also possible to connect the sterilizing water supply pipe 191 with the filter unit flow path pipe (L1, L2, L3, L4) through the connector 265 and the like.

In FIG. 4, the sterilization water supply pipe 191 is connected to the sterilization water supply pipe 191 through the connector 265 at the front of the sediment filter 210 after removing all the filters. Remove the filters (220, 230, 240) and connect the filter flow path pipe (L2, L3, L4) between the separated filter with each other by the connection mechanism (C2, C3, C4) and then the sterilization water supply pipe (191) It may also be connected to the flow path tube (L2). Similarly, the method of connecting the sterilizing water supply pipe 191 to the filter part flow path pipes L1, L2, L3, and L4 may be variously changed.

Meanwhile, in the second to seventh embodiments to be described later, the connection structure of the sterilization water supply pipe 191 corresponding to FIG. 4 is omitted, but in the case of the second to seventh embodiments, the sterilization water supply pipe 191 is similar to FIG. 4 or the like. Can be connected to the filter flow path pipe (L1, L2, L3, L4).

Then, when the drain pipe 195 is connected to the drain port 161, the connection of the flow path is completed.

In this state, the water discharge cocks 261 and 262 and the drain pipes 263 and 264 are kept open so that the pump 140 is operated immediately between the water treatment device 200 and the sterilizing cleaner 100. Be prepared for the flow.

Subsequently, the control unit C opens the one or a part of the inflow ports 111, 112, 113, and 114, and drives the pump 140 and the electrode unit 170 when the flow path switching unit 110 drives the electrode unit 170. Generated in the storage tank 220 (see Fig. 2), tank inlet flow path tube L5 (see Fig. 3) or filter unit flow path tube (L1, L2, L3, L4) through the sterilization water supply pipe 191 (See FIG. 4), and flows back into the electrode sterilization module 100a through the water extraction unit 260.

When this process is performed for a certain time and the concentration of the sterilizing material or cleaning material of the sterilizing wash water detected by the concentration sensor 120 reaches a predetermined value, the pump 140 and the electrode unit 170 are stopped for a predetermined time. Will remain on standby for a while. This standby state is performed to give a time for sterilizing washing water to sterilize and clean the wall surface on the water or the storage tank 220 and the flow path (including the water extraction cock) connected thereto.

Thereafter, the flow path of the flow path switching means 110 may be changed to perform sterilization and cleaning of another tank. For example, if the first inlet 111 and the third inlet 113 is opened first, sterilization and cleaning of the purified water tank 230, the cold water tank 240, and the cold / water discharge coke 261 is performed. Secondly, the second inlet 112 and the fourth inlet 114 are opened to allow sterilization and cleaning of the hot water tank 250 and the hot water discharge coke 262. At this time, if the concentration value detected by the concentration sensor 120 or more than the set value does not need to additionally drive the electrode unit 170 for the sterilization and cleaning of the hot water tank (250), in this case only driving the pump 140 It is also possible.

However, unlike the above-described method, the inlets 111, 112, 113, and 114 are sequentially opened one by one to clean the flow paths connected thereto one by one.

Meanwhile, as described above, when the sterilization and cleaning work is completed, the sterilizing wash water should be discharged to the outside. To this end, the controller C switches the flow path of the drain flow path switching valve 160 to the drain port 161 to allow external discharge of the sterilizing clean water.

Completion of the drainage operation may use the detection of the low water level sensor installed in the storage tank 220, can be confirmed by driving the pump 140 for a predetermined time in consideration of the capacity of the storage tank 220, or the pump 140 You can also check by detecting an overload because water does not flow into the.

As such, when the sterilization and cleaning operation is completed, the rinsing operation of the storage tank 220 may be performed by hand or by using the water that has passed through the filter unit 110, and the sterilization and cleaning apparatus may be before and after the rinsing operation. Can be separated from).

Second Embodiment of Sterilization Cleaning Device

Next, with reference to Figure 5, looks at with respect to the sterilization cleaning apparatus 100 according to a second embodiment of the present invention.

The sterilization cleaning device 100 shown in FIG. 5 is configured of the sterilization cleaning device 100 shown in FIGS. 1 to 4 except that the manifold 110 ′ is installed instead of the flow path switching means 110. Is the same as Therefore, in order to avoid unnecessary duplication, detailed description of the same or similar configuration will be omitted, and only the configuration having a difference will be described.

The manifold 110 ′ shown in FIG. 5 is a manifold connected to a plurality of inlets 111, 112, 113, and 114 connected to the connection pipe 180, and the inflow of water is provided to the electrode unit 170. Done.

As such, when the manifold 110 ′ is installed, since all the flow paths of the water treatment device 200 to which the connection pipe 180 is connected can be performed at once, sterilization cleaning time can be reduced. .

The connection structure of the sterilization washing apparatus 100 and the water treatment device 200 shown in FIG. 5 is the same as that of FIG. 2 except that there is no flow path for the inlets 111, 112, 113, and 114. Detailed description thereof will be omitted.

[Third Embodiment of Sterilization Cleaner]

Next, with reference to Figures 6 and 7, looks at with respect to the sterilizing and cleaning device 100 according to a third embodiment of the present invention.

6 and 7 is the same as the configuration of the sterilization cleaning device 100 shown in FIGS. 1 to 4 except that the electrolyte supply unit 130 is additionally installed. Therefore, in order to avoid unnecessary duplication, detailed description of the same or similar configuration will be omitted, and only the configuration having a difference will be described.

The electrolyte supply unit 130 serves to supply the electrolyte or the salt (including chloride) to the electrode unit 170 in order to facilitate the generation of sterilizing material or cleaning material to obtain a high concentration of sterilizing wash water.

In the conventional electrode device, when the electrolyte is added, the electrolysis reaction (including the redox reaction) is performed smoothly, so that even when the same current or voltage is applied, a high concentration of sterilizing material or cleaning material can be produced.

At this time, the type of electrolyte or salt supplied from the electrolyte supply unit 130 is not limited, but it is preferable to supply chlorides such as NaCl, KCl, NaOCl, etc. to assist in the generation of sterilizing substances. However, in addition to such chlorides, it is also possible to supply other kinds of salts and electrolytes.

In addition, the electrolyte supply unit 130 may be configured as a system for dosing the electrolyte in a liquid state, but in order to simplify use, a solid electrolyte or salt (including chloride) is accommodated in the electrolyte supply unit 130. As water flows into the electrolyte supply unit 130, a solid electrolyte or a salt may be dissolved. To this end, a plurality of distribution holes may be formed in the electrolyte supply unit 130, and a cover may be provided on the top of the electrolyte supply unit 130 to supply the electrolyte or the salt.

On the other hand, as shown in Figure 6, the electrolyte supply unit 130 is preferably configured to be installed at a predetermined distance on the inlet side of the electrode unit 170. That is, by maintaining a distance between the electrolyte supply unit 130 and the electrode unit 170 (for example, by supplying it through a pump), it is possible to prevent a high concentration of undissolved electrolyte or salt (including chloride) from coming into direct contact with the electrode. It is preferable to prevent damage to the electrode installed in the electrode unit 170 by preventing.

In addition, as shown in FIG. 7, the electrolyte or salt (including chloride) supplied from the electrolyte supply unit 130 is introduced into the storage tank 220 through the sterilizing water supply pipe 191 and then sufficiently dissolved and mixed in the electrode. The electrolyte supply unit 130 may be provided on the discharge side of the electrode unit 170 so as to be supplied to the unit 170.

Since the connection structure of the sterilization cleaning apparatus 100 and the water treatment device 200 shown in FIGS. 6 and 7 is the same as that of FIG. 2, a detailed description thereof will be omitted.

[Fourth Embodiment of Sterilization Cleaner]

Next, with reference to Figures 8 to 10, looks at the sterilizing and cleaning device 100 according to a fourth embodiment of the present invention.

The sterilizing and cleaning device 100 shown in FIGS. 8 and 10 is a sterilizing and cleaning device 100 shown in FIGS. 1 to 4 except that an inlet 151 and an inlet flow path switching valve 150 are installed. The same as the configuration of the first embodiment of the sterilization cleaning apparatus 100 shown in FIG. 9 is the sterilization cleaning apparatus shown in FIG. 6 except that the inlet 151 and the inlet flow path switching valve 150 is added. The configuration is the same as that of the third embodiment of 100. Therefore, in order to avoid unnecessary duplication, detailed description of the same or similar configuration will be omitted, and only the configuration having a difference will be described.

The sterilizing and washing apparatus 100 according to the fourth embodiment shown in FIGS. 8 to 10 includes an inlet 151 receiving water from the flow path pipes L1, L2, L3, L4, and L5 of the water treatment device 200. In addition, the inlet flow path switching valve 150 for switching the flow path to selectively supply the water flowing into the inlet 151 and the water introduced through the connecting pipe 180 to the electrode unit 170.

In this case, as shown in FIG. 10, when the water treatment device 200 includes the reverse osmosis membrane filter 213, flow path tubes L1, L2, L3, and L4 of the water treatment device 200 connected to the water inlet 151. , L5 is preferably a flow path tube (L1, L2, L3) provided at the front end of the reverse osmosis membrane filter (213).

Specifically, in the case of water passing through the reverse osmosis membrane filter 213, the amount of total dissolved solids (TDS) is reduced, and when such water is introduced into the electrode unit 170 to generate sterilized washing water, The amount of cleaning material may not be sufficient. In addition, the water that does not pass through the reverse osmosis membrane filter 213 is discarded into the living water (wastewater, concentrated water) through the drain pipe (DL) may be a waste of water.

However, as described above, the filter unit flow path pipe (L1, L2, L3) provided at the front end of the reverse osmosis membrane filter 213 and the inlet 151, the filter unit with water initially introduced into the electrode unit 170 In the case of using the water flowing through the flow path tubes L1, L2, and L3, the amount of total dissolved solids (TDS) flowing into the electrode increases, so that the amount of sterilizing material or cleaning material is increased, which is necessary for sterilization cleaning within a short time. Not only can the concentration of the sterilizing wash water (for example, 0.05 ppm or more be set in the range of 0.07 to several ppm in consideration of the stabilization value required for sterilization washing), but also the waste of water can be prevented and the reverse osmosis membrane filter ( There is an advantage that the life of 213 may not be shortened. At this time, when connecting the first flow pipe (L1) and the inlet 151, the raw water is directly supplied to the electrode unit 170, the second flow pipe (L2) and the third flow pipe (L3) and the inlet 151 ) Is connected to the electrode unit 170, the purified water flowing through the sediment filter 211 or the pre-carbon filter 212 is introduced.

On the other hand, in the hollow fiber membrane type water purifier using the hollow fiber membrane filter instead of the reverse osmosis membrane filter 213, since the amount of the total dissolved solids does not change significantly even when passing through the hollow fiber membrane filter, the flow path tube (L1) provided in the filter unit 210. , L2, L3, L4, L5, even if any flow pipe connected to the inlet 151, there is no significant difference in the amount of production of sterilizing material or cleaning material.

However, when the electrode of the electrode unit 170 is in direct contact with raw water, the life of the electrode may be shortened. Therefore, it is more preferable that a purified water flowing through the at least one filter flows into the electrode unit 170. Therefore, when the filter unit 210 of the water treatment device includes the reverse osmosis membrane filter 213, the filter unit flow path pipes (L1, L2, L3, L4) connected to the inlet 151 is provided in the filter unit 210. It is more preferable that it is the 2nd flow path tube L2 and the 3rd flow path tube L3 through which the purified water flows after passing through at least one filter of the said filter, and before entering into the said reverse osmosis membrane filter.

In addition, as shown in FIG. 9, raw water (for L1) or an integer (for L2 and L3) having a large amount of total dissolved solids is supplied through the flow pipes L1, L2, L3, L4 and L5. Even in the case of providing the electrolyte supply unit 130, it is possible to increase the concentration of the sterilizing wash water at a faster rate.

For example, when the first flow path tube L1 of the filter portion flow path tube and the inlet 151 are connected, the raw water flowing from the first flow path tube L1, the electrolyte supplied from the electrolyte supply unit 130, and the like. The sterilizing clean water may be generated in the electrode unit 170 by using the same. In addition, when the second or third flow path pipes L2 and L3 of the filter part flow path pipe and the water inlet 151 are connected, the sediment filter 210 or the sediment filter 210 and the precarbon filter 220 are connected. The sterilized clean water may be generated by the electrode unit 170 using purified water filtered through) and the electrolyte supplied from the electrolyte supply unit 130. In addition, when the hollow fiber membrane filter is used instead of the reverse osmosis membrane filter 213, since the amount of the total dissolved solids is also present in the water flowing from the fourth flow path tube L4 or the tank inlet flow path tube L5 of the filter unit flow path tube, The sterilized washing water is generated in the electrode unit 170 using water introduced into the inlet 151 from the fourth flow path tube L4 or the tank inlet flow path tube L5 and the electrolyte supplied from the electrolyte supply unit 130. You can do that. As such, even when the amount of total dissolved solids is high in the water flowing into the inlet 151, the electrolyte supply unit 130 may quickly generate high concentration sterilizing wash water even at low power. On the other hand, since the concentration of the sterilizing wash water is measured by the concentration sensor 120, the controller C controls the driving of the electrode unit 170 based on the measured concentration, so that stable sterilization washing is possible.

8 and 9 illustrate that the pump 140 is disposed between the inlet flow path switching valve 150 and the concentration sensor 120 or the electrolyte supply unit 130, the position of the pump 140 is particularly limited. For example, it may be provided at the rear end of the electrode unit 170, or may be provided between the inflow passage switching valve 150 and the electrode unit 170.

Meanwhile, referring to FIG. 10, the connection structure of the sterilizing and cleaning device 100 and the water treatment device 200 shown in FIGS. 8 and 9 is the same as that of FIG. 2 except for the additional connection of the inlet 151. In order to avoid unnecessary duplication, we will only look at the different configurations.

As shown in FIG. 10, the inlet 151 of the sterilizing and cleaning device 100 is provided through the inlet pipe 185 or the flow path pipes L1, L2, L3, L4, and L5 of the water treatment device 200. When the reverse osmosis membrane filter 213 is provided at the filter unit 210, the reverse osmosis membrane filter 213 may be connected to flow path tubes L1, L2, and L3 provided at the front end of the reverse osmosis membrane filter 213. At this time, the water inlet pipe 185 may use any one of the flow pipes (L1, L2, L3) provided at the front end of the reverse osmosis membrane filter 213 or the connector separate from the flow pipes (L1, L2, L3) It can also be used by connecting. However, when the hollow fiber membrane filter is used instead of the reverse osmosis membrane filter 213, any one of the filter part flow path tubes L1, L2, L3, L4 and the tank inlet flow path tube L5 may be used as the inlet pipe 185. It can also be used by connecting these flow pipes through separate connectors. On the other hand, when the tank inlet flow path (L5) and the inlet 151 is connected, the sterilizing water supply pipe 191 may be connected to the storage tank 220.

As such, in the state in which the flow path tubes L1, L2, and L3 and the inlet 151 are connected, sterilization and cleaning operations are performed similarly to FIG.

However, in the case of the sterilization washing apparatus 100 shown in FIG. 10, the flow path tubes L1, L2, and L3 in the electrode unit 170 at the initial stage of the sterilization cleaning operation may include L4 and L5 in the case of the hollow fiber membrane filter. 10 is based on the reverse osmosis membrane filter, in which water (raw water or purified water) having a large amount of total dissolved solids is introduced to generate sterilized clean water having a relatively high concentration in the electrode unit 170. It can be supplied to the storage tank 220 of the 200, and after a predetermined time, the water flows through the connecting pipe 180 to the electrode unit 170 by switching the flow path of the water inlet flow path switching valve 150, This allows the work to continue to generate sterile rinse water. That is, when water is generated through the flow pipes (L1, L2, L3, L4, L5) to generate sterilized washing water and supply it to the storage tank 220, the water level of the storage tank 220 becomes too high and overflows. Since water may be supplied through the flow pipes (L1, L2, L3, L4, L5) only for a predetermined time in consideration of the capacity of the storage tank 220, and then the water of the storage tank 220 It can be configured to generate sterile rinse water while circulating.

Thereafter, when the concentration of the sterilizing wash water detected by the concentration sensor 120 is greater than or equal to a predetermined value, the driving of the pump 140 and the electrode unit 170 is stopped, and then the standby state is maintained for a predetermined time, after which the drain flow path The flow path of the selector valve 160 is switched to the drain port 161 to discharge the sterilizing wash water to the outside.

Meanwhile, in the case of the sterilizing and cleaning device 100 shown in FIG. 10, water is supplied from the flow path pipes L1, L2 and L3 to the inlet 151 from the hollow fiber membrane filter, which may include L4 and L5. It can be used as a rinse water. That is, when the flow path of the inlet flow path switching valve 150 is switched to the inlet 151 and the electrode unit 170 connected for rinsing, and the pump 140 is driven while the electrode unit 170 is not driven, Water obtained through the flow path pipes (L1, L2, L3, L4, L5) may be introduced into the storage tank 220 through the sterilization cleaning device (100). Accordingly, when the rinsing water is filled in the storage tank 220, the rinsing water may be discharged to the outside by switching the flow path of the drain flow channel switching valve 160 to discharge the rinsing water again.

In this case, when using the water obtained through the first to third flow path pipe (L1, L2, L3) as the rinsing water, since the reverse osmosis membrane filter 213 or the hollow fiber membrane filter, which are usually expensive filters, is not used, Waste of the discharged water can be prevented and the life of the reverse osmosis membrane filter 213 or the like can not be unnecessarily reduced.

Meanwhile, the sterilizing and cleaning device 100 illustrated in FIG. 10 includes a control unit C, and the control unit C includes a flow path switching unit 110, an electrode unit 170, a pump 140, and an inflow path switching valve. 150, the driving of the drain flow path switching valve 160 is controlled.

The sterilization cleaning apparatus 100 shown in FIGS. 1 to 4 is identical to the configuration of the first embodiment of FIG. 12, except that an auxiliary tank 155 is added. The configuration is the same as that of the first embodiment. Therefore, in order to avoid unnecessary duplication, detailed description of the same or similar configuration will be omitted, and only the configuration having a difference will be described.

The sterilizing and cleaning device 100 illustrated in FIGS. 11 to 13 includes an auxiliary tank 155.

The auxiliary tank 155 stores water supplied by the user, and the water contained in the auxiliary tank 155 is supplied to the electrode unit 170. At this time, the water contained in the auxiliary tank 155 may be supplied to the electrode unit 170 through the inlet flow path switching valve 150, as shown in Figure 11, by the water head as shown in Figure 12 It is also possible to be supplied directly to the electrode unit 170.

In the case of the fifth embodiment, similar to the fourth embodiment, the user can supply water having a large amount of total dissolved solids such as tap water to the auxiliary tank 155, and the electrode unit 170 sterilizes and cleans through the water. Since water is generated, it is possible to obtain a high concentration of sterilized wash water at an early stage.

In particular, when the user starts the sterilization and cleaning operation through the operation unit (B) by maintaining the water flowing into the auxiliary tank 155 in the electrode unit 170 is applied for a predetermined time to generate a high concentration of sterilizing clean water. It becomes possible. Thereafter, after a predetermined time has elapsed, the pump 140 may be driven to allow the water inside the water treatment device 200 to flow into the sterilization washing apparatus 100.

However, unlike the above, when the user drives the operation unit (B) it is also possible to drive the electrode unit 170 and the pump 140 at the same time.

On the other hand, although not shown, in the case of the fifth embodiment, the configuration of the electrolyte supply unit 130 may be added, it is also possible to add the electrolyte or salt directly to the auxiliary tank (155).

At this time, the water supply to the room temperature water supply unit 270, the cold water supply unit 280 and the hot water supply unit 290 may be performed by the flow path is switched through the flow path switching valve (V1) by the user's selection.

Therefore, since the water treatment device 200 shown in FIG. 14 does not have a tank, the water treatment device 200 does not include a drain pipe, and thus, the connection pipes 183 and 184 connected to the drain pipes 263 and 264 of FIG. You will be disconnected. In addition, the sterilizing water supply pipe 191 may be connected to the tank inlet flow path tube L5 through the connector 265, but if the length of the tank inlet flow path tube L5 is sufficient, the tank inlet flow path tube (directly to the outlet 171) It is also possible to connect L5).

The sterilizing and washing apparatus 100 connected to the water treatment device 200 having such a configuration has the inflow openings 113 and 114 unconnected, so that the unconnected inlet openings 113 and 114 are selected when the flow passage is selected through the flow path switching means 110. It should be operated so as not to open the flow path corresponding to it. To this end, an inlet selection button (not shown) may be installed in the operation unit B of the sterilization cleaning apparatus 100.

It may include one or more connecting pipes 180 connected to the water outlet 260 of the water treatment device 200 to discard the water discharged from the water outlet 260 of the water treatment device 200.

Specifically, one side of the water inlet pipe 185 is composed of filter part flow path tubes (L1, L2, L3, L4) or tank inlet flow path tube L5 of the water treatment device 200, or the filter part flow path tube (L1) , L2, L3, L4 or the tank inlet flow path tube L5 may be connected through a separate connector, etc., and the other side may be connected to the inlet 151 of the electrode sterilization module 100a. Accordingly, the electrode sterilization module 100a may generate sterilized clean water at the electrode unit 170 through the water introduced by being filtered through raw water or at least one filter.

In addition, the sterilizing water supply pipe 191 is located in the rear end of the water supply pipe 185, the filter unit flow path pipe (L1, L2, L3, L4), tank inlet flow path pipe L5 of the water treatment device 200 or It may be connected to the storage tank 220. For example, as shown in FIG. 17, when filter part flow path tubes L1, L2, and L3 are used as inlet pipes 185, the sterilizing water supply pipe 191 may include the filter part flow path tubes L1,. L2, L3 may be connected to the tank inlet flow path pipe (L5) or the storage tank 220 located at the rear end.

In addition, the connection pipe 180 has an electrode sterilization module 100a so that one side may be connected to the water outlet 262 but the other side may drain the sterilizing washing water (or rinsing water) through a drain hole D1 such as a sink. It is also possible not to connect. In addition, when the water outlet 262 directly receives the water through the storage container, the connection pipe 180 may not be installed.

Therefore, the sterilizing and cleaning device 100 according to the eighth embodiment shown in FIGS. 16 and 17 is connected to the inlets 111, 112, 113, and 114 through the flow path switching of the inlet flow path switching valve 150.

After supplying the water to the water treatment device 200 through the sterilization water supply pipe 191, it is also possible to discharge the sterilized washing water through the water outlet 260 without circulating to the electrode sterilization module (100a).

Meanwhile, in the sterilizing and cleaning device 100 according to the eighth embodiment shown in FIGS. 16 and 17, water introduced through the inlet pipe 185 and the inlet 151 may be supplied through the sterilizing water supply pipe 191. It is preferable that the pump 140 is installed at the rear end of the inlet 151.

In addition, the sterilization cleaning apparatus 100 has a concentration sensor 120 is installed at the rear end of the electrode unit 170 to measure the concentration of the sterilizing material or cleaning material contained in the sterilizing wash water generated by the electrode unit 170. It is desirable to be.

Meanwhile, referring to FIG. 17, the inlet 151 of the sterilizing and cleaning device 100 includes an inlet pipe 185 (including flow path pipes L1, L2, L3, L4, and L5 of the water treatment device 200). It may be connected to the flow path pipe (L1, L2, L3, L4, L5) of the water treatment device 200 through, the water is introduced into the electrode sterilization module (100a) through the inlet pipe 185. In this case, when the connection pipe 180 is not connected to the inlets 111, 112, 113, and 114, the inflow flow path switching valve 180 is in a state where the flow path is switched to communicate the inlet port 151 and the electrode unit 170. .

Therefore, the introduced water is introduced into the electrode unit 170 to be sterilized washing water, and the concentration of the sterilizing material or cleaning material included therein is measured by the concentration sensor 120. In this way, the generated sterilizing wash water is supplied to the water treatment device 200 through the sterilizing water supply pipe 191 by the pressure of the pump 140.

At this time, the sterilization water supply pipe 191 is introduced into the sterilization washing water into the filter unit flow path tube, the tank inlet flow path tube (L5), or the storage tank 220 located at the rear end of the flow path in which the inlet pipe 185 is installed.

Then, the sterilized clean water introduced into the water treatment device 200 remains in the water treatment device for a predetermined time while sterilizing and cleaning the flow path tube or the storage tank 220 of the water treatment device.

Thereafter, the sterilizing wash water may be discharged to the outside through the water outlet 260. In this case, one end of the connection pipe 180 may be connected to the water outlet 260, but the other end may be located at a drain D1 such as a sink. As a result, the sterilizing clean water is discharged by opening the water outlet 260.

Thereafter, the rinsing operation of the storage tank 220 may be performed manually, but the rinsing water (raw water or at least part of the water) may be rinsed with the electrode sterilization module 100a through the inlet pipe 185 without driving the electrode unit 170. The rinsing operation may be performed by supplying the water filtered by the filter) and supplying the water treatment device 200 through the sterilizing water supply pipe 191.

[Ninth Embodiment of Sterilization Cleaner]

Next, referring to FIGS. 18 and 19, a sterilizing and cleaning device 100 according to a ninth embodiment of the present invention will be described.

The sterilization cleaning apparatus 100 shown in FIGS. 18 and 19 is obtained from the inlets (111, 112, 113, 114), the flow path switching means 110, and the inlet from the sterilization washing apparatus 100 illustrated in FIGS. 16 and 17. Same as the configuration of the eighth embodiment of the sterilizing and cleaning device 100 shown in FIGS. 16 and 17 except that the flow path switching valve 150, the drain flow path switching valve 160, and the drain port 161 are not provided. In addition, the electrolyte supply unit 130 is added in the case of Fig. 19. Therefore, in order to avoid unnecessary duplication, detailed descriptions of the same or similar components will be omitted, and only different configurations will be described.

Since the sterilization washing apparatus 100 illustrated in FIGS. 18 and 19 is not provided with an inlet flow path switching valve 150, the sterilizing washing water is generated using the water introduced through the inlet 185, and the sterilizing water supply pipe is provided. Supply via 191.

In addition, after the sterilization cleaning is completed, the discharge of the sterilized wash water from the water treatment device 200 is carried out through the opening of the water outlet 260, by installing a connection pipe 180 in the water outlet 260, such as a sink Water is discharged to the drain D1.

In addition, a rinsing operation of the water treatment device 200 may be performed by using the water introduced through the water inlet 185, and the operation may be performed without driving the electrode unit 170.

Next, with reference to FIGS. 20 and 21 will be described with respect to the sterilization cleaning method (S100) of the water treatment device 200 according to another aspect of the present invention.

This sterilization cleaning method (S100) is a water treatment device 200 through the electrode sterilization module (100a) including an electrode unit 170 for generating a sterilization cleaning water containing sterilizing material or cleaning material by applying power to the electrode. The present invention relates to a method for sterilizing and cleaning, but the sterilizing and cleaning apparatus 100 described above may be used, but is not limited thereto.

[First Embodiment of Sterilization Cleaning Method]

First, referring to FIGS. 2 to 4, 10, 13 to 15, 17, and 20, a sterilization cleaning method S100 of the water treatment device 200 according to the first embodiment of the present invention will be described. see.

Sterilization and cleaning method (S100) of the water treatment device 200 according to the first embodiment of the present invention, as shown in Figure 20, connecting the flow path of the water treatment device 200 and the electrode sterilization module (100a) Sterilization cleaning device installation step of installing the connection member 190 (S110), and sterilized clean water generation / supply step to generate the sterilized clean water from the electrode sterilization module (100a) and supply to the water treatment device (200) (S120) Includes, when a predetermined time after the sterilized washing water generation / supply step (S120) is performed or when the concentration of the sterilizing material or cleaning material contained in the water flowing into the electrode unit 170 is more than the set value, Waiting step (S130) for stopping the driving of the electrode unit 170 for a predetermined time, and after the waiting step (S130), to discharge the sterilized wash water through the drain 161 of the electrode sterilizer 100 After sterilizing and washing water draining step (S140) and the sterilizing and washing water draining step (S140), The apparatus may further include a sterilizing and cleaning device separating step S170 for separating the flow path of the water treatment device 200 and the connection member 190 connected to the flow path of the electrode sterilization module 100a.

First, the sterilization cleaning device installation step (S110), the process of connecting one or more connection pipes 180 to the water outlet 260 of the water treatment device 200, and the filter unit flow path tube (L1) of the water treatment device 200 , L2, L3, L4, tank inlet flow path tube (L5) or storage tank 220 will include a step of connecting the sterilization water supply pipe 191. In this case, the connection pipe 180 is detachably connected to at least one of the water extraction cocks 261 and 262 and the drain pipes 263 and 264 constituting the water extraction unit 260.

At this time, the sterilization cleaning device installation step (S110) it is necessary to make the water discharge cock (261, 262) is opened so that the inflow of water can occur when the sterilization cleaning device 100 is operating. In this case, when the water extraction cocks 261 and 262 are mechanical valves, the water extraction cocks 261 and 262 may be positioned in an open state. The valve can be kept open by pressing an electronic valve release button or installing a separate cable to apply an open signal to the electronic valve. The drain pipes 263 and 264 and the raw water shutoff valve V are also preferably opened.

10, 14, and 17, when the water inlet 151 is installed, the filter unit flow path tube L1, L2, L3, L4 of the water treatment device 200 or the tank inlet flow path tube L5. Or an inlet pipe 185 connected to the filter part flow pipe L1, L2, L3, L4 or the tank inlet flow pipe L5 to the inlet 151 of the electrode sterilization module 100a. Process and sterilization in the filter part flow path pipe (L1, L2, L3, L4), tank inlet flow path tube L5 or storage tank 220 of the water treatment device 200, which is located at the rear end of the water supply pipe 185. It may include a process of connecting the water supply pipe 191.

And, as shown in FIG. 17, the connection pipe 180 has one side connected to the water outlet 262, but the other side discards the sterilizing washing water (or rinsing water) into the wastewater through a drain hole D1 such as a sink. It is also possible not to be connected to the electrode sterilization module (100a). In addition, when the water outlet 262 directly receives the water through the storage container, the connection pipe 180 may not be installed.

Next, the sterilized washing water generation / supply step (S120), the water inflow process in which water is introduced into the electrode sterilization module (100a) from the connecting pipe 180 or the water inlet pipe 185, and the electrode unit ( The sterilizing wash water generation process of generating a sterilized wash water by applying power to the 170 and the sterilized wash water through the sterilizing water supply pipe 191 to obtain the filter flow path pipes (L1, L2, L3, L4) and tanks. It may be configured to include a supply process for supplying the flow pipe (L5) or the storage tank (220).

In this case, the water inflow process, the sterilized washing water generation process and the supply process may be performed at the same time, the order before and after may vary depending on the specific configuration of the sterilization washing apparatus (100).

For example, in the case of FIG. 2, the supply process and the water inflow process are simultaneously performed by the driving of the pump 140. Accordingly, in the state where water is introduced into the electrode unit 170, the driving of the electrode unit 170 is performed. By sterilizing wash water generation process can be made. In addition, in the case of FIG. 10, the electrode unit 170 may operate in a state where water through the water inlet 151 flows into the electrode unit 170, and then the pump 140 may be driven. It can also be done at the same time.

On the other hand, the water inflow process may be configured to sequentially open some of the flow paths in communication with the connecting pipe 180 through the flow path switching means (110). For example, one flow path may be sequentially opened from the first inlet 111 to the fourth inlet 114, but in order to perform sterilization and cleaning for each storage tank 220, the purified water tank 230 and the cold water tank ( The first inlet 111 and the third inlet 113 connected to the cold / water discharge coke 261 and the cold / water drain pipe 263 connected to the 240 are first opened, and then the hot water tank ( It is also possible to configure to open the second inlet 112 and the fourth inlet 114 connected to 250.

In addition, the sterilizing washing water generation process may be performed until the concentration detected by the concentration sensor 120 for detecting the concentration of the sterilizing material or the cleaning material included in the water flowing into the electrode unit 170 becomes a set value. It may be configured to drive the electrode unit 170.

At this time, the sterilized wash water generation process, it may be configured to generate a high concentration of sterilized wash water by supplying an electrolyte or a salt (including chloride) to the electrode unit 170 through the electrolyte supply unit 130 (Fig. 6, 7, 9, 14, 15 and 19).

On the other hand, when the raw water (in the case of L1) or the purified water (in the case of L2, L3) with a large amount of total dissolved solids is supplied through the flow path pipe (L1, L2, L3, L4, L5), or the auxiliary tank (155) Even if a large amount of dissolved solids is supplied through the water, the electrolyte supply unit 130 may increase the concentration of the sterilizing clean water at a faster rate even if the electrolyte supply unit 130 is provided. As described above, not only the water contained in the storage tank 220 flows into the electrode unit 170 (see FIGS. 6 and 7), but also a large amount of total dissolved solids in the water flows into the electrode unit 170. Even in this case, if the electrolyte supply unit 130 is further provided (see FIGS. 9, 14, and 15), it is possible to quickly generate a high concentration of sterilized wash water even at low power. On the other hand, since the concentration of the sterilizing wash water is measured by the concentration sensor 120, the controller C controls the driving of the electrode unit 170 based on the measured concentration, so that stable sterilization washing is possible.

In addition, the sterilized washing water generation process, as shown in Figure 10, 14 and 17, when using the flow path pipe (L1, L2, L3; hollow fiber membrane filter initially provided in the water treatment device 200) Is supplied with water from L4 and L5) to generate sterilized wash water, and after a predetermined time, the flow path of the inlet flow path switching valve 150 is switched to generate water and generate sterilized wash water. It can be configured to.

As such, the water supplied through the water inlet 151 from the water treatment device 200 (L1, L2, L3; including L4 and L5 when the hollow fiber membrane filter is used) contains a large amount of total dissolved solids. It is advantageous to generate high concentration of sterilized wash water.

To this end, when the reverse osmosis membrane filter 213 is included in the filter unit 210 of the water treatment device 200, the inlet 151 is provided with flow path pipes (L1, L2, L3) provided at the front end of the reverse osmosis membrane filter (213). It is preferable to connect with.

Unlike this, in the sterilizing wash water generation process, as shown in FIGS. 13 and 15, water is initially supplied from the auxiliary tank 155 for receiving water provided by the user to generate sterilized wash water, and for a predetermined time. After passing, the flow path of the water inlet flow path switching valve 150 may be configured to receive water from the connecting pipe 180 to generate sterilized clean water.

In addition, the supplying step is such that the sterilized washing water is pressurized by the pump 140 to be supplied to the filter part flow path tubes L1, L2, L3, and L4, the tank inlet flow path tube L5, or the storage tank 220. It is composed.

Next, the waiting step (S130) is a concentration of the sterilizing material or cleaning material contained in the water flowing into the electrode unit 170 after a predetermined time after the sterilized washing water generation / supply step (S120) is performed It may be performed when the set value or more, but if the concentration of the sterilizing wash water is high, it is also possible not to perform the waiting step (S130). This waiting step (S130) is performed so that sterilization cleaning is performed while the generated sterilizing water is maintained in the storage tank 220, the flow path and the water discharge cock (261, 262) connected to it for a predetermined time. To this end, by stopping the driving of the pump 140, there is no flow of water between the water treatment device 200 and the sterilization cleaning device, the driving of the electrode unit 170 is also stopped for a certain time.

In this way, after the sterilized clean water generation / supply step (S120), or after the sterilized clean water generation / supply step (S120) and the standby step (S130) are completed, through the drain hole 161 of the electrode sterilizing apparatus 100. The sterilizing wash water drainage step (S140) of discharging the sterilizing wash water is performed.

This sterilizing washing water drainage step (S140) is performed by driving the pump 140 in a state where the flow path of the drain flow path switching valve 160 is switched to the drain port 161. At this time, the electrode unit 170 is not in operation.

On the other hand, the sterilized washing water drainage step (S140) may be terminated by driving the pump 140 for a predetermined time or by detecting that an overload occurs because water does not flow into the pump 140.

2, 13 and 15 after the end of the sterilization washing water drainage step (S140), the rinsing operation may be performed by the user's manual, after the rinsing by manual end sterilization washing apparatus 100 ) May be separated from the water treatment device 200 (S170).

On the contrary, immediately after the sterilizing and washing water draining step (S140) is finished, the sterilizing and washing device 100 may be separated from the water treatment device 200 (S170). In this case, the filter unit 210 may be used. The purified water may be supplied to the storage tank 220 to perform a rinsing operation.

Second Embodiment of Sterilization Cleaning Method

Next, with reference to FIGS. 10, 14, 17 and 21, the sterilization cleaning method (S100) of the water treatment device 200 according to the second embodiment of the present invention will be described.

In the sterilization and washing method S100 of the water treatment device 200 according to the second embodiment of the present invention, unlike the first embodiment shown in FIG. 20, the rinsing water supply step after the sterilizing and washing water draining step S140 is performed (S150). ) And the rinsing water draining step (S160) is performed, after which the sterilization washing apparatus separation step (S170) is performed.

In order to avoid unnecessary duplication, the detailed description of the same or similar parts as the sterilization cleaning method (S100) according to the first embodiment will be omitted, and only the configurations having differences will be described.

First, the rinsing water supply step (S150) is to supply the rinsing water to the tank inlet flow path tube (L5) or the storage tank 220 of the water treatment device 200 after the sterilizing washing water draining step (S140).

10, 14, and 17, the sterilizing and cleaning device 100 of FIGS. 10, 14, and 17 includes flow path tubes L1, L2, and L3 of the water treatment device 200; In the case of the filter (including L4 and L5) are connected, the sterilizing and cleaning device 100 is in a state capable of receiving water from the water treatment device 200.

Therefore, when the inlet 151 and the electrode unit 170 are connected to each other through the inlet flow path switching valve 150, the inlet port 151 and the electrode unit 170 are connected to each other, and the pump 140 is driven without driving the electrode unit 170. Water introduced from the flow path pipes (L1, L2, L3; L4 and L5 in the case of the hollow fiber membrane filter) of the water treatment device 200 through 151 may be supplied to the storage tank 220 through the outlet 171. In this case, the water provided serves as the rinsing water.

This rinsing water supply step (S150) may be continued for a predetermined time in order to make the level of the storage tank 220 to a sufficient degree, may be performed until the water level of the storage tank 220 reaches the full water level. At this time, the high water level detection may be performed using a user's confirmation or a high water level sensor of the storage tank 220.

On the other hand, after the rinsing water supply step (S150) is finished, the waiting step may be performed similarly to the sterilizing wash water generation / supply step (S120), and then the rinsing water draining step (S160) may be performed.

The rinsing water draining step S160 may be performed by driving the pump 140 in a state in which a flow path of the drain flow path switching valve 160 is switched to the drain port 161.

In addition, the rinsing water draining step (S160) may be terminated by driving the pump 140 for a predetermined time or by detecting that an overload occurs because water does not flow into the pump 140.

While the invention has been shown and described with respect to particular embodiments, it will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as set forth in the claims below.
