Hereinafter, the operation of the water purification system 100 capable of supplying carbonated water according to the present embodiment will be described.

[Drinking water / carbonated water supply operation]

First, the operation of supplying drinking water or carbonated water using the purified water system 100 capable of supplying carbonated water according to the present embodiment will be described. The raw water filter 110 filters the foreign substances contained in the raw water and the filtered purified water is stored in the purified water tank 121. A part of the purified water in the purified water tank 121 is cooled by a cooling member (122). On the other hand, when the storage tank 120 is filled with purified water or cold water, the filtering operation of the raw water filter 110 is stopped.

At this time, when the user places the storage container 10 below the water intake nozzle 142 and performs a predetermined operation, the purified water or cold water stored in the storage tank 120 is taken out through the water intake nozzle 142, (10). At the same time, the raw water filter 110 is re-operated to filter the positive integer corresponding to the amount supplied to the user to fill the storage tank 120.

Domestic water generated after being filtered from the raw water filter 110, that is, water containing foreign matter, is drained to the outside.

On the other hand, when the user desires to supply carbonated water, the user places the storage container 10 below the carbonic acid nozzle 153. At this time, the storage container 10 is closely attached to the carbonic acid valve 152 so as to prevent leakage of carbon dioxide gas and smooth supply, and the inner space of the storage container 10 is blocked from the outside.

At the same time, when a user performs a predetermined operation, carbonic acid gas is taken out from the carbonic acid gas cylinder 151 through the hollow of the carbonic acid nozzle 153 and stored in the storage container 10. When the storage container 10 is mounted on the carbonic acid valve 152, the user operates the transfer pump and the cold water stored in the cold water tank 122 flows through the outer surface of the carbonic acid nozzle 153, (10).

Accordingly, the user can receive only the drinking water from the drinking water module 140, receive only the cold water through the carbonated water module 150, or drink the carbonated water by receiving the cold water and the carbon dioxide gas at the same time.

After the user's operation is completed and the supply of the drinking water and the carbonic acid gas-containing carbonated water is completed, when the user removes the storage container 10 from the carbonic acid nozzle 153, it is not discharged due to the internal pressure of the storage container 10 There is a problem that the residual drinking water inside the carbonic acid nozzle that has been leaked may leak.

However, in this embodiment, the residual water control unit controls the drain valve at the same time as stopping the driving of the transfer pump to temporarily open the drainage passage. The drinking water remaining in the supply path and the carbonated water module is exhausted to the outside through the opened drainage path, and the remaining amount of the carbonic acid nozzle is removed.

Therefore, even if the internal pressure of the storage container 10 is released when the user removes the storage container 10 after the residual drinking water in the carbonic acid nozzle is removed, the phenomenon that the drinking water leaks to the outside can be eliminated.

On the other hand, it is preferable that the opening time of the drainage path by the remaining water control unit is determined in consideration of the capacity of the storage tank, the inner diameter of the carbonic acid nozzle, the inner diameter of the supply path, and the like.

[Storage tank disinfection operation]

Fig. 2 is a schematic flow chart of the purification operation of the purified water tank of the water purification system capable of supplying the carbonated water of Fig. 1;

Next, an operation of sterilizing the storage tank 120 of the purified water system 100 capable of supplying carbonated water of this embodiment will be described with reference to the contents shown in FIG.

First, the sterilization control unit determines the sterilization point of the storage tank 120. At this time, the criterion of the sterilization point may be the degree of sterilization interval preset by the user, the quality of the drinking water in the storage tank 120, etc. However, the sterilization point may be determined through various conditions, . In addition, it is possible to determine whether the storage tank 120 is sterilized through a manual control in which a user performs a separate operation instead of the automatic control.

When sterilization is determined, the drinking water stored in the purified water tank 121 and the cold water tank 122 is drained to the outside through the drainage duct.

At the same time, the sterilizing filter 131 is supplied with raw water to produce sterilizing material. In this embodiment, the sterilizing filter 131 is a chloride ion (Cl ^-) in the raw water can be reduced by a chlorine (Cl _2). Describing in detail the manner of reducing the chlorine ion (Cl ^- ) to chlorine (Cl ₂ ), the sterilizing filter 131 includes sterilization terminal portions (not shown) coated with ruthenium oxide (RuOx). By applying electric power (or current or voltage) to the sanitizing terminal, the ruthenium oxide in the sanitizing terminal portion is reduced to chlorine in the raw water (the raw water usually contains chlorine ion in itself).

At this time, the ruthenium oxide coated on the sterilizing terminal serves as a catalyst for lowering the potential difference when reducing the chlorine ion (Cl ^- ) to chlorine (Cl ₂ ). The chlorine thus generated can be directly dissolved in the raw water to become hypochlorous acid (HOCl). Hypochlorous acid (HOCl) is a mixed oxidant that can sterilize bacteria. In this manner, the sterilizing filter 131. In this embodiment, the chloride ion (Cl ^-) in the raw water can be produced by reducing an antiseptic.

Therefore, according to this embodiment, it is possible to continuously produce sterilizing material using only raw water without adding a separate chemical substance.

On the other hand, the sterilizing material generated from the sterilizing filter 131 is supplied into the storage tank 120 in which the drinking water is drained to sterilize the inside of the storage tank 120. When the sterilization operation is completed, the sterilization control unit 132 stops supplying the germicidal material and supplies the purified water from the raw water filter 110 to the storage tank 120 again. At this time, the supplied purified water is supplied for the purpose of removing the germicidal material, and is drained again through the drainage channel.

First, it is determined whether to sterilize the interior of the storage tank 120, draining the drinking water in the storage tank 120, supplying the sterilizing material into the storage tank 120 Sterilizing the water in the storage tank 120, washing the water in the storage tank 120 for washing, and draining the water in the storage tank 120 supplied for washing together with the sterilizing material.

Therefore, according to the water purification system capable of supplying carbonated water according to the embodiment of the present invention described above, it is possible to prevent the drinking water from leaking in the process of removing the storage container, So that a clean internal state can be maintained.

Meanwhile, although the system of the above-described embodiment has been described to include both the carbonated water module and the drinking water module, in another embodiment of the present invention, the drinking water module is excluded, and only the carbonated water module may be provided alone.

The scope of the present invention is not limited to the above-described embodiments, but may be embodied in various forms of embodiments within the scope of the appended claims. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims.
