Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water treatment apparatus capable of sterilizing or cleaning water,

The present invention relates to a water treatment apparatus capable of sterilizing and / or cleaning sterilization and / or cleaning of a storage tank of a water treatment apparatus and a flow path connected thereto, and more particularly to a water treatment apparatus and a sterilization / A sterilizing cleaning water containing a sterilizing substance and / or a cleaning substance (hereinafter, the term 'sterilizing cleaning water' is applied to an electrode to which power is applied) The storage tank or the extraction member provided in the water treatment apparatus can be sterilized and / or cleaned by generating the sterilization and / or cleaning substance, A water treatment device capable of separating the detachable electrode sterilizing module after sterilization or cleaning, and a sterilizing and cleaning method thereof One will.

On the other hand, the water treatment apparatus can be used for a variety of purposes such as industrial wastewater treatment, wastewater treatment, water treatment, ultrapure water production, and the like, and industrial wastewater treatment (including business wastewater treatment) will be. In this way, the water treatment apparatus for drinking water collects raw water (constant water) and generates purified water for drinking, so it may be collectively referred to as a water purifier in a narrow sense. 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 apparatus 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 apparatus" is used to mean the water purifier, the functional water heater, the water heater, the water cooler, the ice water heater, and the like and a device having a combination of these functions. However, although a water purifier is exemplified for the convenience of explanation, such a water purifier should be understood as merely an example of the water purifying 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 the bacteria or microorganisms propagated in the storage tank, a method of sterilizing the storage tank by adding a separate sterilizing agent to the storage tank from the outside has been proposed. However, when the sterilizing agent is injected, the concentration of the sterilizing agent may be higher than necessary, and there is a difference in the amount of the sterilizing agent injected depending on the user or the manager. Therefore, There is a problem that it can be done. Therefore, a plurality of rinsing operations are indispensable after the rinsing operation, and if the rinsing operation is not completed, there is a problem that not only is it harmful to the human body but also complaints due to the chemical smell increase.

In order to solve the problem of the sterilization method, a technique of fixing the electrode sterilization module inside the water purifier has been proposed.

In this electrode sterilization method, sterilization cleaning water generated by application of power is supplied to the storage tank to perform sterilization cleaning of the storage tank, and after the sterilization cleaning operation is completed, a method of draining the sterilization cleaning water of high concentration to the outside is adopted .

However, in the case of such an electrode sterilization method, a costly electrode sterilization module is fixedly installed inside a water purifier, which results in a low cost efficiency in comparison with a use period (sterilization cleaning cycle).

In other words, even in the case of the electrode sterilization method, sterilization cleaning can be performed only if the user selects the sterilization cleaning mode. However, when the sterilization cleaning is performed, the water purifier can not be used during the sterilization cleaning, Since it is necessary to perform an operation for completely removing (rinsing) the washing water, it is difficult for the user to perform the sterilizing cleaning directly, which makes it difficult to perform the sterilizing cleaning from time to time.

For this reason, the electrode sterilization method for sterilizing and cleaning the storage tank using the sterilization cleaning water at a high concentration has not been realized as an actual product.

Furthermore, since the electrode sterilizing module proposed in the prior art aims at sterilizing and cleaning the storage tank, it is difficult to sterilize and clean the channel provided in the water purifier. Further, since the electrode sterilizing module is fixed to the water purifier, it is difficult to change the flow path for sterilization cleaning.

The filter unit 110 is for purifying the raw water by sequentially filtering the raw water and includes a sediment filter 111, a free carbon filter 112, a reverse osmosis membrane filter 113 (or a hollow fiber membrane (ultrafiltration) filter) And a post-carbon filter 114. 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 of the water treatment apparatus (water purifier). For example, a hollow fiber membrane filter may be provided instead of the reverse osmosis membrane filter 113. 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 111, 112, 113, and 114 includes a filter case having a filter element built therein and an external case for housing the filter case, and 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 111, 112, 113, and 114 of the filter unit 110 are not particularly limited to the independent cartridges, and may be a composite filter having two or more filters . For example, as shown in FIG. 2, the sediment filter 111 and the pre-carbon filter 112 shown in FIG. 1 may be configured as a single pre-synthesis compound filter 111a.

The sediment filter 111 functions to adsorb and remove solid matters such as suspended solids, sand, and the like contained in the raw water by supplying raw water from the raw water supply unit. A raw water shutoff valve V1 for selectively shutting off the raw water supplied from the raw water supply unit may be provided at the front end of the sediment filter 111. If the raw water shutoff valve V1 can block the supply of raw water The installation position of the raw water shutoff valve V1 is not limited thereto.

In addition, the free carbon filter 112 is supplied with water that has passed through the sediment filter 111, 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 113 receives the filtered water from the pre-carbon filter 112, and removes heavy 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 113 is connected to a drain pipe D for discharging domestic water generated during filtration of raw water, that is, wastewater (commonly referred to as "concentrated water"

The post-carbon filter 114 functions to adsorb and remove unpleasant taste, odor and color of the filtered water through the reverse osmosis membrane filter 113. The purified water filtered through the post-carbon filter 114 passes through the purified water line And is stored in the storage tank 120.

The filter unit 110 includes a pressurizing pump P capable of supplying water as a pumping pressure to the reverse osmosis membrane filter 113 because the reverse osmosis membrane filter 113 purges water through a membrane having fine pores It is possible.

The filter units 110 are connected to the flow lines L1, L2, L3, L4 and L5 and the filters provided in the filter unit 110 are connected to each other through the filter line channels L1, L2, L3 and L4. And the final filter 114 of the filter unit 110 and the inlet 122 of the storage tank 120 are connected through the tank flow pipe L5.

Hereinafter, in the present specification, 'filter-side flow path pipes (L1, L2, L3 and L4)' are used to refer to flow path pipes flowing into the respective filters 111, 112, 113 and 114, (Constant) flows in the first flow pipe L1 of the filter-equipped flow pipe L1, L2, L3 and L4, and the purified water filtered by the sediment filter 110 flows through the second flow pipe L2. Flow.

It is also possible to provide another member such as a sensor or a valve between the tank flow path L5 and the storage tank 120. However, even if another member is provided, the last filter 114 of the filter unit 110, The entire flow path pipe connecting the tank 120 will be referred to as a tank flow path L5. In the present specification, the filter-side flow path pipes L1, L2, L3, and L4 and the tank flow path L5 are collectively referred to as a "flow pipe".

The storage tank 120 passes through the filter unit 110 and stores purified purified water. When the user requests the purified water, the purified water in the storage tank 120 is discharged through the extraction member (cock) 125.

Specifically, the storage tank 120 stores the purified water passing through the filter unit 110, and includes a purified water tank for storing the purified water at a normal temperature, a cold water tank for storing and cooling the purified water, The hot water tank may include at least a part of the hot water tank. At this time, the purified water tank and the cold water tank may be separately installed, but may be separately installed in one space through a partition wall (separator) capable of flowing water.

In addition, a drain pipe 126 may be provided in the storage tank 120. The drain pipe 126 is used to empty the storage tank 120 when the storage tank 120 is cleaned, the sanitizing wash water is discharged, the rinse water is discharged, and the valve 127 is opened for drainage.

Hereinafter, a water treatment apparatus 200 capable of sterilizing or cleaning according to various embodiments of the present invention will be described with reference to FIGS. 3 to 11. FIG.

[First of the water treatment apparatus Example ]

3 and 4, the water treatment apparatus 200 capable of sterilizing or cleaning according to the first embodiment of the present invention includes a filter unit 110 for filtering raw water, a filter unit 110 for passing the filter unit 110 And sterilizing or cleaning the storage tank 120 through the sterilizing cleansing water generated by the removable electrode sterilizing module 210, including a storage tank 120 for storing the filtered water, and a removable electrode sterilizing module 210, .

The filter unit 110 and the storage tank 120 have been described with reference to FIGS. 1 and 2. Hereinafter, the detachable electrode sterilizing module 210 and its connection structure will be described. FIG. 3 shows an example in which four filters are formed in the same manner as FIG. 1, and FIG. 4 shows an example in which a pre-synthesis compound filter 111a is installed in the same manner as in FIG. 3 and 4 will be described together, since the remaining components are the same except for the configuration of the filter unit 110. [

3 and 4, when the sterilization or cleaning of the storage tank 120 is required, the removable electrode sterilizing module 210 is installed on the flow path connected to the storage tank 120, And an electrode device (see 212 in Figs. 5, 6, 8 to 11) for generating a sterilizing cleaning water containing a sterilizing or cleaning substance by being applied.

The electrode device (212 of FIG. 5 or the like) generates sterilizing cleaning water containing a sterilizing substance or a cleaning substance by applying power to the electrodes.

As an example, the electrode device 212 can be used to electrolyze incoming water (herein, the term electrolysis will be referred to as including a "redox reaction") to produce a mixed oxidant (MO) Sterile < / RTI > sterilizing function and / or a substance having a cleaning function.

The electrode device 212 passes water between the electrodes of 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.

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) The kind of the salt (including chloride), and the like, and it is included in the category of the electrode device 212 according to the present invention if sterilizing cleaning water (electrolytic disinfecting water) can be produced through the electrode .

That is, even when generating electrolytic solution or salt (including chloride) supplied from the electrolyte supply part (212 in FIG. 5 or the like) to generate sterilizing cleansing water as described later, I would say that.

The detachable electrode sterilizing module 210 is installed on a flow path connected to the storage tank 120 when sterilization or cleaning of the storage tank 120 and a channel (including an extraction member) connected thereto is required, 120 may be separated after the sterilization or cleaning of the cells has ended.

At this time, the removable electrode sterilizing module 210 connects the filter unit 110 and the storage tank 120 so as to generate sterilizing cleansing water by using filtered purified water while passing through at least a part of the filter unit 110 Or the like.

3 and 4, when the sterilizing or cleaning is required, the removable electrode sterilizing module 210 is installed in the flow path between the post carbon filter 114 and the storage tank 120, It can be separated after the cleaning operation is completed.

When the removable electrode sterilizing module 210 is connected to the filter unit 110 and the removable electrode sterilizer module 210 is operated, the sterilizing clean water is generated and stored in the storage tank 120. Of course, in order to perform germicidal cleaning, it is necessary to drain some or all of the water contained in the storage tank 120 before the germicidal cleaning operation.

In order to install the removable electrode sterilizing module 210 in the sterilizing water treatment apparatus 100, the removable electrode sterilizing module 210 must be connected to the flow path of the sterilizing water purifying apparatus 100.

At this time, it is also possible to connect the flow paths of the detachable electrode sterilizing module 210 and the sterilizing and cleaning water treatment apparatus 100 by separate connection pipes 251 and 252, but as shown in FIGS. 3 and 4, It is also possible to use a flow pipe provided in the water treatment apparatus 100 to be cleaned.

3 and 4, the inlet side of the removable electrode sterilizing module 210 is connected to the post-carbon filter 114 through a connection pipe 251, and the connection pipe 252 of the outlet side is connected to the post- The tank flow path L5 can be used. In this case, the sterilizing water generated in the detachable electrode sterilizing module 210 can flow through the tank flow path L5, thereby achieving the effect of sterilizing and cleaning the tank flow path L5.

A water treatment apparatus 200 capable of sterilizing or cleaning according to an embodiment of the present invention includes a controller C for controlling at least one of water supply to the storage tank 120 and water discharge from the storage tank 120, ). ≪ / RTI >

The control unit C is provided in the sterilizing and cleaning water treatment apparatus 100. The detachable electrode sterilizing module 210 is connected to the control unit C by a wired or wireless signal connection line CL, (C).

That is, after the detachable electrode sterilizing module 210 is installed in the flow path of the sterilizing water treatment apparatus 100, the detachable electrode sterilizing module 210 is connected to the control unit C through the signal connection line CL, When the cleaning operation is started, the sterilizing cleaning operation can be performed automatically.

For example, if the user selects a sterilizing cleaning operation start button provided in the sterilizing water cleaning apparatus 100 after the removable electrode sterilizing module 210 is installed, the control unit C opens the valve 127 When the control unit C opens the raw water shutoff valve V1 and drives the electrode device 212, the detachable electrode sterilizing module V1 is opened through the filter unit 110, The sterilizing rinse water generated by the introduction of the purified water into the storage tank 210 may be filled up to the set water level (preferably, the full water level) of the storage tank 120. When the water level of the storage tank 120 reaches the set water level, the control unit C closes the raw water shutoff valve V1 and stops driving the electrode device 212. [ The controller C may open the valve 127 and discharge the sterilization cleansing water through the drain pipe 126 to the outside through the drain pipe D after maintaining a predetermined period of time so that proper sterilization and cleaning can be performed . The water can be supplied to the storage tank 120 in a state in which the electrode unit 212 of the removable electrode sterilizing module 210 is not driven through the control unit C and can be directly supplied to the drinking water or used as a rinse water .

In this way, the sterilizing and cleaning operation can be automatically performed by connecting the detachable electrode sterilizing module 210 to the control unit C of the water sterilizing apparatus 100 to be sterilized.

[The second of the water treatment apparatus Example ]

Next, a water treatment apparatus 200 capable of sterilizing or cleaning according to a second embodiment of the present invention will be described with reference to FIGS. 5 and 6. FIG.

The water treatment apparatus 200 shown in FIGS. 5 and 6 is different from the water disinfecting apparatus 200 except that the position of the connecting portion on the water inlet side of the removable electrode sterilizing module 210 is different and the detailed structure of the removable electrode sterilizing module 210 is different The configuration of the water treatment apparatus 200 shown in Figs. 3 and 4 is the same as that of the water treatment apparatus 200 shown in Figs. Therefore, the description of the same or similar configuration will be omitted in order to avoid unnecessary duplication.

5 and 6, the water sterilizing or cleaning device 200 includes a removable electrode sterilizing module 210 having a constant flow valve 211 and / or an electrolyte supply portion 213.

The constant flow rate valve 211 is installed at the front end of the electrode device 212 to supply a predetermined flow rate of water to the electrode device 212 to generate a sterilization clean water having a constant concentration. Specifically, since the concentration of sterilizing cleansing water generated in accordance with the flow rate of the electrode device 212 is different, it is necessary to control the flow rate of the sterilizing water to produce an efficient and stable sterilizing cleansing water. .

In addition, the electrolyte supplying part 213 plays a role of supplying an electrolyte or a salt (including chloride) to the electrode device 212 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 the salt supplied from the electrolyte supply unit 213 is not limited, but it is preferable to supply a chloride such as NaCl, KCl, NaOCl, etc. to help the sterilizing material. However, it is also possible to supply other kinds of salts and electrolytes in addition to these chlorides.

At this time, the removable electrode sterilizing module 210 connects the filter unit 110 and the storage tank 120 so as to generate sterilizing cleansing water by using filtered purified water while passing through at least a part of the filter unit 110 Or the like. However, the water introduced into the removable electrode sterilizing module 210 is not required to be highly filtered through the reverse osmosis membrane filter 113 or the hollow fiber membrane filter, which is excellent in filtration performance and relatively expensive since it is water that is discharged after the sterilizing and cleaning operation.

Therefore, it is more preferable that the removable electrode sterilizing module 210 generates the sterilizing cleansing water by using the filtered purified water while passing through only a part of the filters of the filter unit 110.
