Description

TECHNICAL FIELD [0001] The present invention relates to a sterilizing method of a water treatment apparatus,

The present invention relates to a germicidal cleaning apparatus for a water treatment apparatus and a germicidal cleaning method 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. More particularly, (Hereinafter, the term 'germicidal cleansing water' refers to water containing a germicidal substance and / or a cleansing substance produced by an electrode to which power is applied) And sterilizing cleaning water is introduced into a flow path, a storage tank, or an outflow coke provided in the water treatment apparatus, thereby sterilizing and / or cleaning the flow path, storage tank, or outflow coke in the water treatment apparatus. And a germicidal cleaning method for a water treatment apparatus.

On the other hand, the water treatment apparatus (water treatment apparatus) can be used for various purposes such as industrial wastewater treatment, wastewater treatment, water treatment, ultrapure water treatment, etc., And a cleaning method. In this way, the water treatment device for drinking water is called a water purifier in a narrow sense because it generates purified water for drinking after receiving raw water (constant water). The water purifier is configured to supply raw water (constant water) to the user, which is filtered at the filter unit, and can provide hot water and / or cold water to the user by heating / cooling the purified water at room temperature do.

In addition, not only water but also various functional water such as ionized water, carbonated water, and oxygenated water are supplied to the water treatment equipment for drinking. In addition, there are a water heater, a water cooler, and an ice maker which heat or cool water supplied from a water supply means such as a water bottle or generate ice. In the present specification, the term water treatment equipment is used to mean a generic term for a water purifier, a functional water heater, a water heater, a water cooler, an ice water heater, etc., and a device having a combination of these functions. However, although a water purifier is exemplified for convenience of explanation, such a water purifier should be understood as merely an example of the water treatment apparatus according to the present invention.

Generally, the water purifier is divided into a hollow fiber membrane type and a reverse osmosis membrane type depending on the purification method.

Among these, the reverse osmosis membrane type water purifier is known to be superior to other purification methods developed to date in the removal of contaminants.

The water purifier of the reverse osmosis membrane type uses a sediment filter which receives raw water from a water conduction or the like and removes dust, debris and various suspended substances through a fine filter of about 5 microns, and a sediment filter which removes carcinogens (THM) It is composed of a free carbon filter that removes chemical substances and residual chlorine such as synthetic detergents and insecticides, and a reverse osmosis membrane of 0.0001 micron. It filters heavy metals such as lead and arsenic as well as sodium and various pathogens. A reverse osmosis membrane filter (RO membrane filter) that discharges water through the reverse osmosis membrane filter, and a post-carbon filter that removes unpleasant taste, smell, pigment, and the like contained in the water that has passed through the reverse osmosis membrane filter.

In addition, a hollow fiber membrane filter (ultrafiltration filter, UF) is used instead of the reverse osmosis membrane filter. The hollow fiber membrane filter is a porous filter having pores having a size of several tens to several hundred nanometers (nm), and it removes contaminants in water through numerous micro pores distributed on the membrane surface.

However, such a water purifier has the problem that microorganisms or germs remaining in the pores of the post-carbon filter can flow into the storage tank, so that microorganisms can reproduce again in the storage tank. In addition, bacteria and microorganisms may infiltrate into the water stored in the storage tank and propagate from outside, and water may be generated on the inner wall of the storage tank.

In order to sterilize bacteria or microorganisms propagated in the storage tank, a technique of sterilizing the storage tank by adding an additional sterilizing agent to the storage tank from the outside has been proposed.

However, since the method of supplying the sterilization agent is performed by the user or the water purifier manager through the separate sterilization agent supply operation, the sterilization operation is troublesome and the sterilization management is inefficient. That is, when the sterilizing agent is injected, it is impossible to inject the sterilizing agent automatically, or even if the injection is automatically performed, the sterilizing agent must be periodically filled, which is very troublesome.

In addition, when the sterilizing agent is injected, the concentration of the sterilizing agent may be higher than necessary, depending on the case. Since there is a difference in the amount of the sterilizing agent input depending on the user or manager, There is a problem that it can be done. Therefore, a plurality of rinsing operations are essential after the rinsing operation, and if the rinsing operation is not completed, not only is it harmful to the human body, but also complaints due to the chemical smell increase.

In addition, since the water purifier manager needs to perform the sterilizing agent supply work, the cost for disinfection treatment of the water purifier is incurred, and the user may feel the burden on the service cost.

Particularly, since the water purifier itself is not sterilized and cleaned but is often carried out by the service person, there is a problem that the reliability of the water purifier is deteriorated

The conditions under which the sterilizing agent is melted or eluted differs depending on the water purifier operating conditions (for example, raw water pressure, flow rate, etc.). For example, when the flow rate is small, the sterilization concentration may be relatively high. On the contrary, when the flow rate is large, the sterilization concentration is low, and thus there is a great difficulty in sterilization control. Therefore, when the concentration of the sterilizing agent is high, odor can be generated.

In addition, sterilizing materials generated by sterilizing chemicals have a low odor and very high OCl ^- substances. Therefore, odor is much generated and sterilizing performance is only about 1/70 of that of HOCl. Therefore, in order to sterilize the same tank capacity, A disinfecting substance of the present invention is required.

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

However, even in the case of the above-mentioned patent application of the present applicant, a neutralization process for neutralizing a drug due to the toxicity of the sterilizing drug is required as in the case of manually sterilizing the sterilizing drug, And there is a disadvantage that the subsequent rinsing operation takes a long time. In addition, since the patent application requires direct supply of the sterilizing agent and the neutralizing agent, there is a difficulty in that a lot of manual work is required for sterilization cleaning.

Therefore, a sterilization cleaning method different from the conventional one is required.

The present invention has been made to solve at least some of the problems of the prior art as described above, and it is an object of the present invention to provide a germicidal cleaning apparatus for a water treatment apparatus and a germicidal cleaning method for a water treatment apparatus capable of performing germicidal cleaning of a water treatment apparatus by a simple method The purpose.

[First embodiment of sterilizing and cleaning apparatus]

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

The connection member 190 includes at least one connection pipe 180 connected to the water outlet 260 of the water treatment device 200 and filter connection pipe lines L1, L2, L3, and L4 of the water treatment device 200, And a sterilizing water supply pipe 191 connected to the tank intake flow path L5 or the storage tank 220. [ In the present specification (including claims), the filter-side flow pipes L1, L2, L3, and L4 are used to refer to the flow pipes that flow into the respective filters 210, 220, 230, and 240, Raw water (constant water) flows through the first flow path L1 and purified water flows through the second flow path L2 through the sediment filter 210. In this specification, the filter-side flow path pipes (L1, L2, L3, L4) and the tank intake flow pipe (L5) are collectively referred to as a flow pipe.

The connection pipe 180 is detachably connected to at least one of the water outlet corks 261 and 262 and the drain pipes 263 and 264 constituting the water outlet 260 of the water treatment apparatus 200, The water supply pipe 191 is detachably connected to the filter side flow pipes L1, L2, L3 and L4 of the water treatment apparatus 200, the tank intake flow pipe L5 or the storage tank 220.

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 can be connected between the cold / constant water outflow cork 261 and the inlet port 111 through which the water contained in the hot water tank 240 can be connected and the hot water outflow coke 262 and the inlet 112 may be connected to the second connection pipe 182.

The number of the connection pipes 180 and the type of the 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 the hot water tank 240 is not provided or when the hot water tank 240 is not sterilized and cleaned, the hot water outlet cock 262 and the hot water drain pipe 264 are not provided. The connection pipes 182 and 184 may not be connected to each other. In the case where the flow path of the water treatment apparatus 200 is added, an additional connection pipe 180 may be provided.

The sterilization water supply pipe 191 is connected to the filter side flow path pipes L1, L2, L3, L4 (see FIG. 4) for sterilizing and cleaning the storage tank 220 and the flow path ), A tank intake flow pipe (L5), or a storage tank (220).

2 to 4, one end of the connection pipe 180 is connected to the water outlet 260 of the water treatment apparatus 200, and the other end of the connection pipe 180 is connected to the electrode sterilizing module 100a The other end of the connection pipe 180 may be connected to the inlet sterilization module 100a of the water treatment device 100 as shown in Figures 17 to 20, The disinfecting washing water discharged from the water outlet 260 of the washing machine 200 may be placed in the drain so as to be discharged through a drainage hole (including a temporary storage container for storing the sterilizing washing water) such as a sink or the like. It is also possible to discharge sterilization cleansing water directly from the water outlet 260 using the storage container without connecting the connection pipe 180 to the water outlet 260 in the water treatment device 200.

The electrode sterilizing module 100a may include a housing 101 and an electrode unit 170 and a pump 140 provided inside the housing 101. Alternatively, ), A concentration sensor 120, a drain passage switching valve 160, and a controller (C).

In the electrode unit 170, sterilizing cleaning water containing a sterilizing substance or a cleaning substance (in the present specification, 'sterilizing washing water' is water that can perform at least one of sterilization and cleaning functions Quot;). ≪ / RTI >

As an example, the electrode unit 170 may be formed by electrolyzing the incoming water (herein, the term "electrolysis" will be referred to as "oxidation-reduction reaction") to form a mixed oxidant (MO) Sterile < / RTI > sterilizing function and / or a substance having a cleaning function.

In this electrode unit 170, water is passed between electrodes having different polarities, thereby sterilizing or destroying the microorganisms and bacteria remaining in the water. In general, the sterilization of water by electrolysis involves direct oxidation which directly oxidizes the microorganisms in the anode and various mixed oxidants (MO: Mixed Oxidant) such as residual chlorine, ozone, OH radical, oxygen Radicals and the like oxidize the microorganisms.

As shown in FIG. 1, in an embodiment of the present invention, it is possible to generate a sterilizing material without adding a separate electrolyte (hereinafter, referred to as a concept including both salts and chlorides) It is preferable to coat the electrode body of the electrode with ruthenium (Ru). 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 and voltage conditions can be set to maximize the activity of such ruthenium (Ru) catalysts.

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, the ruthenium-coated electrode is heated to a high temperature by oxidation Ruthenium oxide is the only material remaining on the surface of the electrode because it changes ruthenium oxide (RuOx). However, since the material coated at the beginning of electrode formation is ruthenium, the term 'ruthenium coated' I will use it to do. Therefore, it is effective to set the maximum voltage to 30 volts, more preferably 24 volts, and the power to be within 12 watts in order to prevent the ruthenium (Ru) catalyst activity and coating damage.

When ruthenium (Ru) is used for the electrode body, the life of the electrode can be usually shortened. However, since the electrode can be driven at a low current, the life of the electrode can be prevented from being shortened. In order to further increase the lifetime of the ruthenium (Ru) coated electrode, it is desirable to further reduce the current. For this purpose, it is preferable that the cathode electrode, which is a counter electrode, is formed only of titanium (Ti) electrode without any additional 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, and when the current is lowered, the power is also reduced and the life of the cathode electrode and the anode electrode is prolonged .

As described above, according to the electrode unit 170 according to an embodiment of the present invention, the ruthenium (Ru) coating electrode is used as the anode electrode, the titanium (Ti) electrode is used as the cathode electrode, , It is possible to obtain the advantageous effect that a desired concentration of the germicidal material can be produced with no additional chloride (electrolyte) addition and at low current or low power. However, the material of the electrode included in the electrode unit 170 according to the present invention is not limited to the material described above, and various modifications may be made in accordance with the embodiments.

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 positive electrodes and one negative electrode may be used, or one positive electrode and one negative electrode may be used. However, in order to minimize the current value while achieving the concentration of the germicidal material, (-) electrode, a (+) electrode and a (-) electrode are arranged in this order.

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

On the other hand, the sterilization cleansing water (electrolytic disinfection water) obtained by using an electrode to which power is supplied has a different form of chlorine present in the water depending on the pH, and thus the sterilizing power is also very different. Electrolytic water, weakly acidic electrolytic water, strong alkaline electrolytic water, and electrolytic sodium hypochlorite.

In order to produce various disinfection cleansing water (electrolytic disinfecting water) as described above, the material and spacing of the electrodes, the magnitude of the power source (voltage or current) applied, the presence or absence of electrolytes or salts (including chloride) (Including chloride) and the like, and it is included in the category of the electrode unit 170 according to the present invention if sterilizing cleansing water (electrolytic disinfecting water) can be produced through the electrode .

That is, even when the sterilizing cleaning water is generated by using the electrolyte or salt (including chloride) supplied from the electrolyte supply part 130 as described later, it is said that it corresponds to the electrode part 170 according to the present invention .

The pump 140 applies a pressing force to supply the sterilization cleansing water generated in the electrode unit 170 to the channel of the water treatment apparatus 200. The water flowing into the sterilizing and washing apparatus 100 through the pump 140 is changed into the sterilizing washing water and flows through the sterilizing water supply pipe 191 to the flow path of the water treatment apparatus 200, L2, L3, and L4, the tank intake flow pipe L5, or the storage tank 220, respectively.

1 to 4, the pump 140 is disposed between the drainage passage switching valve 160 and the concentration sensor 120. However, if the pump 140 can be supplied to the water treatment apparatus by pressing the water, For example, may be provided at the rear end of the electrode unit 170, or may be provided between the drain passage switching valve 160 and the electrode unit 170.

The flow path switching unit 110 may be configured to sequentially open a part of the flow paths communicating with the at least one connection pipe 180 connected to the water outlet 260 of the water treatment apparatus 200 .

The flow path switching means 110 sequentially opens the plurality of inflow ports 111, 112, 113, 114 one by one and blocks the remaining inflow ports, or sequentially opens some of the inflow ports and keeps the remaining inflow ports closed .

For example, the first inlet 111 connected to the first connection pipe 181, the second inlet 112 connected to the second connection pipe 182, and the like may be sequentially opened, but the cold water tank 240, The first inlet 111 and the third inlet 113 connected to the first connection pipe 181 and the third connection pipe 183 are simultaneously opened to open the flow channels of the first connection pipe 181 and the third connection pipe 183 at the same time, And then the second inlet 112 and the fourth inlet 114 may be simultaneously opened and the remaining inlets 111 and 113 may be blocked.

In this way, the passage switching unit 110 sequentially opens some of the flow paths, thereby sterilizing and cleaning the storage tank 220 of the water treatment equipment 200 corresponding to the opened inlet port and the flow path connected thereto. The flow path switching means 110 may be constructed using a variety of known valves or opening and closing means, such as a plurality of solenoid valves, disk valves, and the like.

In addition, the concentration sensor 120 senses the concentration of the germicidal substance or the cleaning substance contained in the water flowing into the electrode unit 170. The concentration sensor 120 may be constituted by a sensor for measuring the ion concentration, but is not limited thereto as long as it can detect the concentration of the germicidal substance or the cleaning substance. Also, if the concentration of the germicidal substance or the cleaning substance can be sensed, the installation position of the concentration sensor 120 is not particularly limited.

In addition, the outflow channel switching valve 160 switches the flow path to the drain port 161 in order to drain the water flowing into the sterilizing module 100a to the outside. 1, the outflow channel switching valve 160 is provided with a flow path for sending the water introduced through the inlet ports 111, 112, 113 and 114 to the outlet port 171 through the electrode section 170, , And the drainage pipe (195) connected to the drainage port (161). The outflow channel switching valve 160 switches the flow path to the outlet port 171 when discharging sterilization cleansing water to the outside or discharging the rinse water to the outside after the sterilizing and cleaning operation of the water treatment apparatus 200 is completed.

1, a control unit (not shown) for controlling the driving of the flow path switching unit 110, the concentration sensor 120, the pump 140, the drain path switching valve 160 and the electrode unit 170, C) may be installed. The control unit C drives the pump 140 and the electrode unit 170 at the beginning of the sterilization and cleaning operation and controls the flow path switching unit 110 to open and close the flow path switching unit 110 so that the various flow paths of the water treatment equipment 200 can be sequentially sterilized and cleaned. And stops the driving of the pump 140 and the electrode unit 170 when the concentration detected by the concentration sensor 120 is equal to or higher than the predetermined value.

When the sterilizing cleaning operation is completed, the controller C switches the flow path of the drain passage switching valve 160, drives only the pump 140 without driving the electrode unit 170, The pump 140, and the electrode unit 170 so as to discharge the water to the outside.

The electrode sterilizing module 100a according to the present invention includes a display unit D for displaying an operation state of the electrode sterilizing module 100a and an operation unit B for operating the operation of the electrode sterilizing module 100a And the display contents and the operation contents can be variously modified and changed.

For example, the operation unit B may include various selection buttons such as a sterilization start button, a sterilization stop button, an inlet selection button, and the like. The display unit D may include a disinfection state, a standby state, a rinsing state, Etc. may be displayed by illumination or an alarm.

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

2 to 4, a conventional water purifier 200 includes a filter unit 210, a storage tank 220, and a water outlet 260.

The filter unit 210 is a filter for sequentially purifying raw water and includes a sediment filter 211, a free carbon filter 212, a reverse osmosis membrane filter 213 (or a hollow fiber membrane (ultrafiltration) filter) And a post carbon filter 214. The type, number, and order of the filters may be changed depending on the filtration method of the water treatment apparatus (water purifier) or the filtration performance required for the water treatment apparatus (water purifier). For example, a hollow fiber membrane filter may be provided instead of the reverse osmosis membrane filter 213. Such a hollow fiber membrane filter is a porous filter having a pore size of several tens to several hundred nanometers (nm), and it removes contaminants in water through numerous micropores distributed on the membrane surface.

Each of the filters 211, 212, 213, and 214 includes a filter case having a filter element built therein and an external case for housing the filter case. The raw water, which is received in the external case, And then discharged out of the outer casing.

However, in the present invention, as described above, the filters 211, 212, 213, and 214 of the filter unit 210 are not particularly limited to the independent cartridges, and may be a composite filter having two or more filters . For example, the sediment filter 211 and the pre-carbon filter 212 may be configured as a single pre-processing compound filter.

The sediment filter 211 functions to adsorb and remove solid matter such as suspended solids, sand, and the like contained in the raw water by receiving raw water from the raw water supply unit. In this case, a raw water shutoff valve V for selectively shutting the raw water supplied from the raw water supply unit may be installed at the front end of the sediment filter 211. However, if the raw water shutoff 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 free carbon filter 212 is supplied with water that has passed through the sediment filter 211, and through the adsorption method of activated carbon, it is possible to remove harmful chemicals such as volatile organic compounds, carcinogens, synthetic detergents, (For example, HOCl or ClO) components.

The reverse osmosis membrane filter 213 receives the filtered water from the pre-carbon filter 212 to remove fine organic and inorganic substances such as bacteria and heavy metals and other metal ions contained in the water through the membrane having fine pores. The reverse osmosis membrane filter 213 is connected to a drain pipe DL for discharging domestic water generated during filtration of raw water, that is, wastewater (conventionally referred to as "concentrated water"

The post-carbon filter 214 functions to adsorb and remove unpleasant taste, odor and color of the filtered water through the reverse osmosis membrane filter 213. The purified water filtered through the post-carbon filter 214 passes through the purified water line And is stored in the storage tank 220.

The filter unit 210 includes a pressurization pump 215 that can supply water as a pumping pressure to the reverse osmosis membrane filter 213 because the reverse osmosis membrane filter 213 purifies water through a membrane having fine pores It is possible.

The last filter 214 and the storage tank 220 of the filter unit 210 are connected to the tank intake flow pipe L5, Lt; / RTI > It is also possible to provide another member such as a sensor or a valve between the tank intake flow path L5 and the storage tank 220. However, even if another member is installed, the last filter 214 of the filter unit 210 The entire flow pipe connecting the storage tank 220 will be referred to as a tank intake flow pipe L5.

Meanwhile, the storage tank 220 passes through the filter unit 210 and stores the purified water, and discharges the purified water through the outgoing cocks 261 and 262.

In detail, the storage tank 220 stores the purified water passing through the filter unit 210, and includes a purified water tank 230 for storing the purified water at a normal temperature, a cold water tank 240 for storing the purified water, And a 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 separately installed, but may be separately installed in one space through a partition wall (separator) through which water can be circulated.

The outflow corks 261 and 262 may be provided as a water outlet 260 for supplying water stored in the storage tank 220 to a user. At this time, the cold / constant water exit cock 261 may be configured to supply the user with purified water or cold water by the user's choice, and the hot water outflow coke 262 may be configured to supply hot water to the user. 2 to 4, purified water and cold water are supplied to the user through one cold / constant water outflow coke 261, but it is also possible that separate outgoing cocks for supplying purified water and cold water are provided, respectively.

Drain pipes 263 and 264 may be provided as the water outlet 260 connected to the storage tank 220. These drain pipes 263 and 264 are used to empty the storage tank 220 when cleaning the storage tank 220, discharging the sanitizing wash water, discharging the rinse water, and the like. At this time, the cold / cold water drain pipe 263 is connected to the cold water tank 240 to drain purified water and cold water, and the hot water drain pipe 264 is connected to the hot water tank 250 to drain the hot water.

The process of connecting the sterilizing and washing apparatus 100 to the water treatment apparatus 200 shown in FIGS. 2 to 4 may be performed by connecting the connection tube 180 and the sterilizing water supply tube 191 of the sterilizing and washing apparatus 100 to the water treatment apparatus 200).

2 to 4, the cold / constant water outflow 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 / So that the hot water outlet cock 262 and the second inlet 112 are connected to each other. Also, the cold / water drain pipe 263 and the third inlet 113 are connected to each other through the third connecting pipe 183, and the hot water drain pipe 264 and the fourth inlet 114).

As shown in FIG. 2, the storage tank 220 (or the purified water tank 230) and the water outlet 171 are connected to each other through the sterilizing water supply pipe 191. Alternatively, as shown in FIG. 3, it is also possible to connect the sterilizing water supply pipe 191 to the tank intake flow pipe L5 through a connector 265 or the like.

4, all or a part of the filters provided in the filter unit 210 are removed, and the filter-side flow path pipes L1, L2, L3, and L4 are connected to the connection mechanism C1 C2, C3 and C4 and then connect the sterilization water supply pipe 191 to the filter side flow pipe L1, L2, L3, L4 through the connector 265 or the like.

4, the sterilization water supply pipe 191 is connected to the front end of the sterilization filter 210 through the connector 265 or the like. However, after the sediment filter 210 is left, After the filters 220, 230 and 240 are removed and the filtration flow path pipes L2, L3 and L4 between the separated filters are connected to each other by the connection mechanisms C2, C3 and C4, the sterilization water supply pipe 191 And may be connected to the flow pipe L2. Similarly, the manner in which the sterilizing water supply pipe 191 is connected to the filter-side flow path pipes L1, L2, L3, and L4 can be variously changed.

In the second to seventh embodiments described later, the connection structure of the sterilization water supply pipe 191 corresponding to FIG. 4 is omitted. In the second to seventh embodiments, the sterilization water supply pipe 191, L2, L3, and L4 to the filter-side flow path pipes L1, L2, L3, and L4.

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

In this state, when the pump 140 is operated so that the outgoing cocks 261 and 262 and the drain pipes 263 and 264 are kept open, water is supplied between the water treatment device 200 and the sterilizing and washing device 100 immediately So that the flow can be made.

When the flow path switching unit 110 opens one or a part of the inlet ports 111, 112, 113 and 114 and drives the pump 140 and the electrode unit 170, the control unit C controls the electrode unit 170, The sterilizing washing water produced in the sterilizing water supply pipe 191 is supplied to the storage tank 220 (see FIG. 2), the tank intake flow path L5 (see FIG. 3) (See FIG. 4), and flows into the electrode sterilizing module 100a through the water outlet 260 again.

When the concentration of the germicidal or cleaning substance in the sterilization cleaning water detected by the concentration sensor 120 reaches a predetermined value, the driving of the pump 140 and the electrode unit 170 is stopped, While maintaining the standby state. This standby state is performed in order to give the sterilizing cleansing water time to sterilize the water or the wall surface on the storage tank 220 and the flow path (including the outflow coke) connected thereto.

Thereafter, the flow path of the flow path switching means 110 can be changed to perform germicidal cleaning of another tank. For example, if the first inlet 111 and the third inlet 113 are opened to sterilize the purified water tank 230, the cold water tank 240, and the cold / constant water outflow coke 261, The second inlet 112 and the fourth inlet 114 are opened secondarily so that the sterilization and cleaning of the hot water tank 250 and the hot water outlet cock 262 can be performed. At this time, if the concentration value detected by the concentration sensor 120 is equal to or higher than the preset value, it is not necessary to further drive the electrode unit 170 for germicidal cleaning of the hot water tank 250 and the like. In this case, It is also possible to do.

However, unlike the above, it is also possible to sequentially open the inlets 111, 112, 113 and 114 one by one and clean the flow paths connected thereto one by one.

On the other hand, when the germicidal cleaning operation is completed as described above, the germicidal washing water must be discharged to the outside. For this purpose, the controller C switches the flow path of the drain passage switching valve 160 to the drain port 161 side so that the sterilization cleansing water can be discharged to the outside.

Completion of such draining may be accomplished by sensing the low water level sensor installed in the storage tank 220 or by driving the pump 140 for a certain period of time in consideration of the capacity of the storage tank 220, ) Due to the inflow of water.

When the sterilization and cleaning operation is completed, the rinsing operation of the storage tank 220 can be performed manually or using the water passed through the filter unit 110. Before and after the rinsing operation, ). ≪ / RTI >

[Second embodiment of sterilizing and washing apparatus]

Next, a sterilizing and cleaning device 100 according to a second embodiment of the present invention will be described with reference to FIG.

The sterilizing and cleaning device 100 shown in FIG. 5 is similar to the sterilizing and cleaning device 100 shown in FIGS. 1 to 4 except that a manifold 110 ' . Therefore, in order to avoid unnecessary redundancy, a detailed description of the same or similar configuration will be omitted, and only differences will be discussed.

The manifold 110 'shown in FIG. 5 is a manifold that is connected to a plurality of inlets 111, 112, 113, and 114 connected to the connection pipe 180 and supplies the introduced water to the electrode unit 170 .

As described above, when the manifold 110 'is installed, all the channels of the water treatment device 200 connected to the connection pipe 180 can be cleaned at one time, and the sterilization cleaning time can be shortened .

The connection structure of the sterilizing and cleaning device 100 and the water treatment device 200 shown in FIG. 5 is the same as that of FIG. 2 except that the flow path to the inlet ports 111, 112, 113, A detailed description thereof will be omitted.

[Third embodiment of sterilizing and washing apparatus]

Next, a sterilizing and cleaning device 100 according to a third embodiment of the present invention will be described with reference to FIGS. 6 and 7. FIG.

The sterilizing and cleaning apparatus 100 shown in FIGS. 6 and 7 is the same as the sterilizing and cleaning apparatus 100 shown in FIGS. 1 to 4 except that the electrolyte supply unit 130 is additionally provided. Therefore, in order to avoid unnecessary redundancy, a detailed description of the same or similar configuration will be omitted, and only differences will be discussed.

The electrolyte supply part 130 functions to supply electrolyte or salt (including chloride) to the electrode part 170 in order to smoothly generate a germicidal substance or a cleaning substance to obtain a high concentration of germicidal cleansing water.

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

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

The electrolyte supply part 130 may be a system for dosing the electrolyte in a liquid state. However, in order to simplify use, a solid electrolyte or a salt (including chloride) is contained in the electrolyte supply part 130 A configuration may be adopted in which the solid electrolyte or salt is dissolved while the water flows into the electrolyte supply part 130. For this purpose, a plurality of through holes may be formed in the electrolyte supply part 130, and a cover may be provided at an upper end of the electrolyte supply part 130 for supplying the electrolyte or the salt.

Meanwhile, as shown in FIG. 6, it is preferable that the electrolyte supply part 130 is configured to be installed at a predetermined distance from the inlet side of the electrode part 170. That is, by providing a distance between the electrolyte supply part 130 and the electrode part 170 (for example, by feeding through a pump), a high concentration of undissolved electrolyte or salt (including chloride) It is preferable to prevent damage to the electrode provided on the electrode unit 170. [

7, the electrolyte or salt (including chloride) supplied from the electrolyte supply unit 130 flows into the storage tank 220 through the sterilizing water supply pipe 191, The electrolyte supply part 130 may be provided on the discharge side of the electrode part 170 so as to be supplied to the unit part 170. [

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

[Fourth Embodiment of the Sterilizing and Cleaning Apparatus]

Next, a sterilizing and cleaning device 100 according to a fourth embodiment of the present invention will be described with reference to FIGS. 8 to 10. FIG.

The sterilization and washing apparatus 100 shown in Figs. 8 and 10 is similar to the sterilization and washing apparatus 100 shown in Figs. 1 to 4 except that the inlet 151 and the inlet flow switching valve 150 are provided. The sterilizing and cleaning apparatus 100 shown in Fig. 9 is the same as that of the first embodiment of the sterilizing and cleaning apparatus 100 shown in Fig. 6 except that the inlet 151 and the inlet flow switching valve 150 are added. (100) according to the third embodiment of the present invention. Therefore, in order to avoid unnecessary redundancy, a detailed description of the same or similar configuration will be omitted, and only differences will be discussed.

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

10, when the water treatment apparatus 200 includes the reverse osmosis membrane filter 213, the flow pipes L1, L2, L3, and L4 of the water treatment apparatus 200 connected to the inlet 151 And L5 are flow pipe lines L1, L2, and L3 disposed 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 solid matter (TDS) becomes small. When sterilizing washing water is generated by flowing such water into the electrode unit 170, The amount of cleaning substance may not be sufficient. In addition, the water that has not passed through the reverse osmosis membrane filter 213 is discharged to the domestic water (wastewater, concentrated water) through the drain pipe DL, thus wasting water may occur.

However, as described above, the filter-side flow paths L1, L2, and L3 provided at the front end of the reverse osmosis membrane filter 213 are connected to the inlet 151, When the water flowing through the tubes (L1, L2, L3) is used, the amount of the total dissolved solids (TDS) flowing into the electrode increases, and the amount of the germicidal substance or the cleaning substance is increased. (For example, 0.05 ppm or more, which may be set to about 0.07 to several ppm in consideration of the stabilization value required for the germicidal cleaning), as well as to prevent the waste of water and to prevent the reverse osmosis membrane filter 213 It is possible to avoid shortening the lifetime of the battery. When the first flow pipe L1 and the inlet 151 are connected to each other, 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 The filtered purified water flows into the electrode unit 170 through the sediment filter 211 or the free carbon filter 212.

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, the amount of the total dissolved solids does not greatly change even though the hollow fiber membrane filter passes through the filter, , L2, L3, L4, and L5 are connected to the inlet 151, there is no significant difference in the amount of the germicidal material or the cleaning material.

However, if the electrode of the electrode unit 170 directly contacts the raw water, the life of the electrode may be shortened. Therefore, it is more preferable that the purified water passing through at least one filter flows into the electrode unit 170. Therefore, when the filter unit 210 of the water treatment apparatus includes the reverse osmosis membrane filter 213, the filter-side flow path pipes L1, L2, L3, and L4 connected to the inlet 151 are provided in the filter unit 210 And a second flow pipe (L2) and a third flow pipe (L3) through which purified water flows before being introduced into the reverse osmosis membrane filter after passing through at least one filter among the filters.

9, raw water (in the case of L1) or constants (in the case of L2 and L3) having a large amount of total dissolved solids are supplied through the flow pipes L1, L2, L3, L4 and L5 It is possible to increase the concentration of the sterilizing cleaning water at a higher rate.

For example, when the first flow pipe (L1) and the fresh water inlet (151) are connected to each other, the raw water flowing in the first flow pipe (L1) and the electrolyte supplied from the electrolyte supply unit It is possible to generate the sterilizing washing water in the electrode unit 170 by using the washing water. In the case where the second or third flow path pipes L2 and L3 of the filter side flow path and the inlet 151 are connected to each other, the sediment filter 210 or the sediment filter 210 and the free carbon filter 220 The electrolytic water supplied from the electrolytic solution supply unit 130, and the like, may be used to generate sterilizing cleansing water in the electrode unit 170. [ When a hollow fiber membrane filter is used in place of the reverse osmosis membrane filter 213, the amount of total dissolved solids is large also in the water introduced from the fourth flow pipe L4 and the tank intake flow pipe L5 of the filter side flow pipe, The sterilizing washing water is generated in the electrode unit 170 using the water introduced into the inlet 151 from the fourth flow path L4 or the tank inlet flow path L5 and the electrolyte supplied from the electrolyte supplying unit 130, . As described above, even when the amount of the total dissolved solids in the water flowing into the inlet 151 is large, the electrolytic solution supply unit 130 can quickly generate sterilized cleaning water at a high concentration even at low power. On the other hand, the concentration of sterilization cleansing water is measured by the concentration sensor 120, and the control unit C controls driving of the electrode unit 170 based on the measured concentration, so that stable sterilizing cleaning can be performed.

8 and 9, the pump 140 is shown as being disposed between the intake passage switching valve 150 and the concentration sensor 120 or the electrolyte supply portion 130. However, the position of the pump 140 is particularly limited And may be provided at the rear end of the electrode unit 170 or between the inlet passage switching valve 150 and the electrode unit 170 as an example.

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 To avoid unnecessary redundancy, we only look at configurations that have differences.

10, the inlet 151 of the sterilizing and washing apparatus 100 is connected to the flow pipes L1, L2, L3, L4, L5 of the water treatment apparatus 200 through the inlet pipe 185, When the filter unit 210 is provided with the reverse osmosis membrane filter 213, it may be connected to the flow pipe L1, L2, L3 provided at the front end of the reverse osmosis membrane filter 213. The inlet pipe 185 may use any one of the flow pipes L1, L2 and L3 provided at the upstream end of the reverse osmosis membrane filter 213. The inlet pipe 185 may be a separate connector from the flow pipes L1, May also be used. However, when a hollow fiber membrane filter is used in place of the reverse osmosis membrane filter 213, any of the filter-side flow path pipes L1, L2, L3, L4 and the tank intake flow pipe L5 may be used as the water supply pipe 185 , They may be connected to these flow pipes through separate connectors. On the other hand, when the tank intake flow pipe L5 and the inlet 151 are connected to each other, the sterilized water supply pipe 191 may be connected to the storage tank 220.

In this way, in the state where the flow pipes L1, L2, L3 and the inlet 151 are connected, a sterilizing cleaning operation is performed similarly to FIG.

However, in the case of the sterilizing and cleaning device 100 shown in FIG. 10, the flow path L1, L2 and L3 (in the case of the hollow fiber membrane filter, L4 and L5) (Raw water or purified water) having a large amount of total dissolved solids is introduced through the reverse osmosis membrane filter as a reference, and the electrode unit 170 generates sterilization clean water having a relatively high concentration through the electrode unit 170, 200 may be supplied to the storage tank 220 or the like and after a predetermined time has elapsed, the flow path of the water supply flow path switching valve 150 may be switched so that the water introduced through the connection pipe 180 may be introduced into the electrode portion 170 Whereby the operation of generating sterilizing washing water can be continued. That is, when the sterilizing washing water is generated by using the water introduced through the flow pipes L1, L2, L3, L4 and L5 and supplied to the storage tank 220, the water level of the storage tank 220 becomes excessively high, L2, L3, L4, and L5 for a predetermined period of time in consideration of the capacity of the storage tank 220, and then, the water in the storage tank 220 So as to generate sterilizing washing water while circulating the sterilizing washing water.

Thereafter, when the concentration of the sterilization rinse water sensed by the concentration sensor 120 becomes equal to or greater than a predetermined value, the driving of the pump 140 and the electrode unit 170 is stopped, The flow path of the switching valve 160 is switched to the drain port 161 side to discharge the sterilizing cleansing water to the outside.

On the other hand, in the case of the sterilization and washing apparatus 100 shown in FIG. 10, water is supplied from the flow pipes L1, L2 and L3 (which may include L4 and L5 in the case of the hollow fiber membrane filter) This can be used as a rinse water. That is, in order to rinse, the flow path of the inlet flow path switching valve 150 is switched to the state in which the inlet 151 and the electrode unit 170 are connected, and the pump 140 is driven in a state where the electrode unit 170 is not driven Water received through the flow lines L1, L2, L3, L4, and L5 may be introduced into the storage tank 220 through the sterilizing and cleaning device 100. [ Accordingly, when the rinse water is filled in the storage tank 220, the rinsing water can be discharged to the outside by switching the flow path of the drainage passage switching valve 160 to discharge the rinsing water again.

In this case, when water obtained through the first to third flow path pipes (L1, L2, L3) is used as the rinsing water, the reverse osmosis membrane filter 213 or the hollow fiber membrane filter, which is generally an expensive filter, is not used. Waste of water to be discharged can be prevented and the lifetime of the reverse osmosis membrane filter 213 and the like can be prevented from being unnecessarily reduced.

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, (150) and the drainage passage switching valve (160).

[Fifth embodiment of sterilizing and cleaning apparatus]

Next, a sterilizing and cleaning device 100 according to a fifth embodiment of the present invention will be described with reference to FIGS. 11 to 13. FIG.

The sterilizing and cleaning apparatus 100 shown in Figs. 11 and 13 is similar to the sterilizing and cleaning apparatus 100 shown in Figs. 1 to 4 except that an auxiliary tank 155 and an inlet flow switching valve 150 are provided. The sterilizing and cleaning apparatus 100 shown in Fig. 12 is the same as the construction of the first embodiment of the sterilizing and cleaning apparatus 100 shown in Figs. 1 to 4 except that an auxiliary tank 155 is added. Is the same as the configuration of the first embodiment of Fig. Therefore, in order to avoid unnecessary redundancy, a detailed description of the same or similar configuration will be omitted, and only differences will be discussed.

The sterilizing and cleaning apparatus 100 shown in Figs. 11 to 13 includes an auxiliary tank 155. Fig.

The auxiliary tank 155 stores the 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 intake passage switching valve 150 as shown in FIG. 11. However, as shown in FIG. 12, Or may be directly supplied to the electrode unit 170.

In the case of the fifth embodiment, similarly to the fourth embodiment, the user can supply the auxiliary tank 155 with a large amount of total dissolved solids, such as tap water, and the electrode unit 170 can be sterilized It is possible to obtain sterilization cleansing water at a high concentration at an early stage.

Particularly, when the user starts the germicidal cleaning operation through the operation unit B, the water introduced into the auxiliary tank 155 is held in the electrode unit 170 to which power is applied for a predetermined period of time, . After a predetermined time has elapsed, the pump 140 may be driven to allow water in the water treatment apparatus 200 to flow into the sterilizing and washing apparatus 100.

However, unlike the above, it is also possible that the electrode unit 170 and the pump 140 are simultaneously driven when the user drives the operation unit B.

Although not shown, the configuration of the electrolyte supply part 130 may be added in the case of the fifth embodiment, and it is also possible to add electrolytes or salts directly to the auxiliary tank 155.

The flow path structure and sterilization / cleaning operation other than those described above are the same as those of the fourth embodiment, and therefore, detailed description thereof will be omitted.

[Sixth Embodiment of the Sterilizing and Cleaning Apparatus]

Next, a sterilizing and cleaning apparatus 100 according to a sixth embodiment of the present invention will be described with reference to FIG.

14 is the same as the fourth embodiment of the germicidal cleaning apparatus 100 shown in FIG. 9, except that the water treatment apparatus 200 connected to the sterilizing and cleaning apparatus 100 FIG.

The water treatment apparatus 200 shown in FIG. 14 is different from the water treatment apparatus 200 shown in FIGS. 2 to 4, 10 and 13 in that a temperature changing unit 220 'is provided instead of the storage tank 220 .

The water treatment apparatus 200 shown in FIGS. 2 to 4, 10, and 13 has a storage tank 220 for storing water, but the water treatment apparatus 200 shown in FIG. 14 includes a storage tank 220, .

More specifically, the temperature changing unit 220 'of the water treatment apparatus 200 shown in FIG. 14 includes a room temperature supplying unit 270 for taking out the water that has passed through the filter unit 210 at a room temperature, A cold water supply unit 280 provided with an instantaneous cooling device for cooling and supplying the cold water, and a hot water supply unit 290 provided with an instantaneous heating device for heating and supplying. At this time, the water supply to the hot water supply unit 270, the cold water supply unit 280, and the hot water supply unit 290 can be performed by switching the flow path through the channel switching valve V1 at the user's option.

Therefore, the water treatment apparatus 200 shown in FIG. 14 does not have a drain pipe, and accordingly, the connection pipes 183 and 184 connected to the drain pipes 263 and 264 of FIG. 2 and the like It is not connected. The sanitizing water supply pipe 191 may be connected to the tank intake flow path L5 through the connector 265. If the length of the tank intake flow path L5 is sufficient, L5) may be connected.

Since the inlet ports 113 and 114 are not connected to each other, the sterilizing and cleaning device 100 connected to the water treatment device 200 having such a configuration can not remove the connection ports 113 and 114 when the flow path is selected through the flow path switching means 110, To open the corresponding flow path. For this, an inlet selection button (not shown) may be provided on the operation part B of the sterilizing and washing device 100. [

As shown in FIG. 20, the sterilizing and cleaning method (S100) of the water treatment apparatus 200 according to the first embodiment of the present invention connects the flow path of the water treatment apparatus 200 and the flow path of the electrode sterilizing module 100a A sterilizing cleaning device generating / supplying step (S120) for generating sterilizing cleaning water from the electrode sterilizing module (100a) and supplying the sterilizing cleaning water to the water treatment device (200) If the concentration of the germicidal substance or the cleaning substance contained in the water flowing into the electrode unit 170 is equal to or greater than the predetermined value after the lapse of a predetermined time after the sterilizing cleansing water generating / supplying step S120 is performed, (S130) for stopping the driving of the electrode unit 170 for a predetermined period of time; and after the waiting step S130, discharging the sterilizing washing water through the drain hole 161 of the electrode sterilizer 100 After the sterilizing washing water drainage step (S140) and the sterilizing washing water drainage step (S140) And a sterilizing and cleaning device separation step S170 for separating the connection member 190 connected to the flow path of the water sterilization apparatus 200 and the flow path of the sterilizing module 100a.

The sterilizing and cleaning device installation step S110 includes the steps of connecting one or more connection pipes 180 to the water outlet 260 of the water treatment device 200 and connecting the filter connection pipe line L1 of the water treatment device 200 , L2, L3, and L4, and connecting the sterilizing water supply pipe 191 to the tank intake flow path L5 or the storage tank 220. At this time, the connection pipe 180 is detachably connected to at least one of the outflow corks 261 and 262 and the drain pipes 263 and 264 constituting the outflow unit 260.

At this time, the sterilizing and cleaning device installation step (S110) needs to make the outgoing cocks 261 and 262 open so that water can be introduced when the sterilizing and cleaning device 100 is operated. If the outgoing cocks 261 and 262 are mechanical valves, the outgoing cocks 261 and 262 may be placed in the open state. If the outgoing cocks 261 and 262 are electromagnetic valves, The valve can be kept open by an operation such as pressing an electronic valve opening button or installing a separate cable to apply an opening signal to the electronic valve. It is also preferable that the drain pipes 263 and 264 and the raw water shutoff valve V are also opened.

As shown in FIGS. 10, 14 and 17, when the inlet 151 is provided, the filter-side flow paths L1, L2, L3 and L4 of the water treatment apparatus 200 or the tank intake flow path L5 Or connecting the water inlet pipe 185 connected to the filter unit flow path pipes L1, L2, L3 and L4 or the tank water inlet pipe L5 to the inlet 151 of the electrode sterilizing module 100a L3 and L4 of the water treatment device 200 located at the rear end of the water supply pipe 185 and sterilization of the tank water supply flow pipe L5 or the storage tank 220 And connecting the water supply pipe 191.

17, one side of the connection pipe 180 is connected to the water outlet 262, and the other side of the connection pipe 180 is connected to the water outlet D1 of the sink or the like to discharge sterilization clean water (or rinse water) It is not possible to connect the sterilizing module 100a to the electrode sterilizing module 100a. In addition, when water is directly received from the water outlet 262 through the storage container, the connecting pipe 180 may not be installed.

Next, the sterilizing cleansing water generating / supplying step S120 includes a water inflow process in which water is introduced into the electrode sterilizing module 100a from the connection pipe 180 or the water supply pipe 185, 170) to generate sterilizing cleansing water; and sterilizing washing water producing step of sterilizing cleansing water through the sterilizing water supply pipe (191) to the filter side flow path pipes (L1, L2, L3, L4) To the flow pipe L5 or to the storage tank 220. [0050]

At this time, the water inflow step, the sterilizing washing water generating step and the supplying step may be performed at the same time, but the order of the sterilizing and washing apparatus 100 may vary according to the specific structure of the sterilizing and 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, and thus, in the state where the water is introduced into the electrode unit 170, A sterilizing washing water producing process by the above-mentioned method can be performed. In the case of FIG. 10, the electrode unit 170 may be operated in a state in which water is introduced into the electrode unit 170 through the inlet 151, and then the pump 140 may be driven. Or may be performed simultaneously.

Meanwhile, the water inflow process may be configured to sequentially open some of the flow paths communicating with the connection pipe 180 through the flow path switching means 110. [ For example, one channel may be sequentially opened from the first inlet 111 to the fourth inlet 114. However, in order to perform sterilizing cleaning for each storage tank 220, the purified water tank 230 and the cold water tank Water outflow coke 261 and the cold / water drain pipe 263 connected to the hot water tank 240 after the sterilizing and cleaning operation is completed by first opening the first inlet 111 and the third inlet 113 connected to the cold / The second inlet 112 and the fourth inlet 114 connected to the first and second inlet and outlet ports 250 and 250 are opened.

The sterilizing cleaning water producing process may be performed until the concentration detected by the concentration sensor 120 sensing the concentration of the germicidal substance or the cleaning substance contained in the water flowing into the electrode unit 170 reaches the set value. So that the electrode unit 170 can be driven.

At this time, the sterilizing cleaning water generating step may be configured to supply electrolytic solution or salt (including chloride) to the electrode unit 170 through the electrolyte supply unit 130 to generate sterilization cleansing water at a high concentration (FIG. 6, 7, 9, 14, 15 and 19).

On the other hand, when raw water (in case of L1) or constants (in case of L2 and L3) having a large amount of total dissolved solids are supplied via the flow pipes L1, L2, L3, L4 and L5, It is possible to increase the concentration of the sterilizing cleansing water at a higher rate when the electrolytic water supply unit 130 is provided even though the amount of the total dissolved solids is high. 6 and 7), water having a large amount of total dissolved solids in the water flows into the electrode unit 170 (see FIGS. 6 and 7) as well as when the water contained in the storage tank 220 flows into the electrode unit 170 9, 14, and 15), it is possible to quickly generate sterilization cleansing water at a high concentration even at a low power level. On the other hand, the concentration of sterilization cleansing water is measured by the concentration sensor 120, and the control unit C controls driving of the electrode unit 170 based on the measured concentration, so that stable sterilizing cleaning can be performed.

10, 14, and 17, the sterilizing cleaning water producing process may be performed by using the flow path pipes L1, L2, L3 provided in the water treatment apparatus 200, (Including L4 and L5) to generate sterilizing cleansing water. After a lapse of a predetermined time, water is supplied from the connection pipe 180 by switching the flow path of the water supply channel switching valve 150 to generate sterilizing cleansing water .

As described above, the total amount of dissolved solid matter is included in the water supplied through the inlet 151 from the L 1, L 2, and L 3 (including L 4 and L 5 when the hollow fiber membrane filter is used) provided in the water treatment apparatus 200 It is advantageous to generate sterilization cleansing water of high concentration.

When the reverse osmosis membrane filter 213 is included in the filter unit 210 of the water treatment apparatus 200, the flow pipes L1, L2 and L3 provided at the front end of the reverse osmosis membrane filter 213 are connected to the inlet 151, .

Alternatively, as shown in FIGS. 13 and 15, the sterilizing washing water producing process may be performed by supplying water from an auxiliary tank 155 that initially receives water supplied by a user to generate a sterilizing washing water, The flow path switching valve 150 may be switched so that water is supplied from the connection pipe 180 to generate sterilization cleansing water.

The supply step is a step of supplying the sterilization clean water to the filter side flow path pipes L1, L2, L3 and L4, the tank intake flow path pipe L5 or the storage tank 220 by the pump 140 .

Next, in the waiting step S130, a predetermined period of time after the sterilizing washing water generating / supplying step S120 is performed or the concentration of the germicidal substance or cleaning substance contained in the water flowing into the electrode unit 170 It is also possible that the waiting step S130 is not performed if the concentration of the sterilizing washing water is high. This waiting step S130 is performed so that the sterilized cleaning water generated is maintained in the storage tank 220 and the flow path connected to the storage tank 220 and the outflow corks 261 and 262 for a predetermined period of time. For this, the driving of the pump 140 is stopped so that no water flows between the water treatment apparatus 200 and the sterilizing and washing apparatus, and the driving of the electrode unit 170 also stops for a predetermined time.

After the sterilization cleansing water generating / supplying step S120 or the sterilizing cleansing water generating / supplying step S120 and the waiting step S130 are completed, the water is discharged through the drain port 161 of the electrode sterilizer 100 A sterilizing washing water drainage step (S140) for discharging the sterilizing washing water is performed.

The sterilization cleansing water drainage step S140 is performed by driving the pump 140 in a state where the flow path of the drain path switching valve 160 is switched to the drain port 161 side. At this time, the electrode unit 170 does not operate.

On the other hand, the sterilization cleansing water drainage step S140 may be terminated by driving the pump 140 for a predetermined period of time or sensing that an overload occurs due to the inflow of water into the pump 140. [

After the completion of the sterilization cleansing water drainage step (S140), the rinsing operation can be performed manually by the user in the case of FIGS. 2, 13, and 15. After the rinsing by the manual operation is completed, Can be separated from the water treatment apparatus 200 (S170).

Alternatively, the sterilizing and cleaning device 100 may be separated from the water treatment device 200 (S170) immediately after the sterilization cleansing water drainage step S140 is completed. In this case, The purified water may be supplied to the storage tank 220 to perform the rinsing operation.

Therefore, when the pump 140 is driven in a state where the inlet 151 and the electrode 170 are connected through the inlet flow switching valve 150 and the electrode 170 is not driven, The water introduced from the flow pipes L1, L2 and L3 (including L4 and L5 in the case of the hollow fiber membrane filter) of the water treatment apparatus 200 through the outlet port 151 can be supplied to the storage tank 220 through the outlet port 171 , The water provided at this time functions as a rinse water.

The rinsing water supply step (S150) may be continued for a certain period of time to make the water level of the storage tank 220 a sufficient level, and may be performed until the water level of the storage tank 220 becomes a full water level. At this time, the full water level detection may be performed using a user's confirmation or a full water level sensor of the storage tank 220 or the like.

On the other hand, after the rinsing water supply step S150 is finished, the waiting step may be performed similarly to the sterilizing washing water generating / supplying step S120, and then the rinsing water discharging step S160 may be performed.
