Water purification device that supplies sterilizing water {WATER PURIFYING APPARATUS FOR SUPPLYING STERILIZED WATER}

The present invention relates to a water purification device, and in particular, a pipe for supplying sterilizing water independent of a pipe for supplying cooking water is formed in the purified water, cold water, or hot water outlet, so that cooking water and sterilizing water are supplied, and purified water, cold water, or hot water is supplied. It relates to a water purification device that supplies sterilizing water that performs a sterilizing function for the water outlet.

Recently, water purifiers that provide cooking water in addition to drinking purified water have been developed. The cooking water provided by the water purifier is purified water that has passed through a predetermined filter, and is generally used in the kitchen for washing dishes, fruits, etc., or for cooking food. On the other hand, general cooking water is just purified water, so when using cooking water to wash dishes, fruits, etc., you must use a separate detergent or sterilizer, or use a recently developed sterilizer in addition to achieve effective cleaning or sterilization. can be brought.

The sterilizing water purifier of the prior art, Korean Patent Publication No. 10-2013-0006005, provides sterilizing water through a separate piping from the cooking water piping. Since the sterilizing water piping is constructed separately, the flow path becomes complicated and the product price increases. . In addition, the conventional technology does not provide the function of sterilizing the water outlet and internal pipes including the purified water outlet of the water purifier.

In addition, conventional sterilizing water purifiers were unable to maintain a constant sterilizing concentration when the flow rate of raw water (or purified water) was varied. For example, when the flow rate of raw water is below the standard flow rate, a conventional sterilizing water purifier was able to supply sterilizing water with a desired sterilizing concentration. However, when the flow rate of raw water exceeds the standard flow rate, sterilizing water with a sterilizing concentration lower than the desired sterilizing temperature had no choice but to supply. In addition, when the total dissolved solids (TDS) concentration of the raw water is above a certain concentration, the conventional sterilizing water purifier was able to supply sterilizing water with the desired sterilizing concentration, but the total dissolved solids concentration of the raw water was lower than a certain concentration. In this case, the conventional sterilizing water purifier had a problem in that it could not produce and supply sterilizing water with the desired sterilizing concentration.

In addition, in a conventional sterilizing water purifier, the built-in sterilizing module continues to operate even when the raw water (or purified water) received is blocked (e.g., water cut off, etc.), so the sterilizing module is burned out (heat is generated and the sterilizing module explodes). or swelling symptoms) may occur.

In the present invention, a pipe for supplying sterilizing water independent of the pipe for supplying cooking water is formed at the purified water, cold water, or hot water outlet, thereby minimizing the number of pipes in the water purification device, and generating sterilizing water inside the water purification device to The purpose is to provide a water purification device that variably adjusts the supply flow path of sterilizing water to sterilize each of the water outlets (purified water outlet, hot water outlet, cold water outlet, and sterilizing water outlet) and supplies sterilizing water with a constant sterilization concentration. .

When it is confirmed that the purified water flows into the water outlet equipped with the water generator, it is preferable to operate the sterilizing water generator to discharge the sterilizing water into the supply pipe.

In addition, when the inflow of purified water is blocked or a sterilizing water stop selection input is obtained from the input unit while performing the sterilizing water discharge mode, the control unit controls the purified water valve to be in a blocked state and operates the sterilizing water generator. It is desirable to stop and end the sterilizing water discharge mode.

It consists of a control unit 50. However, in this specification, the operations of the components that perform the hot water/cold water generation operation, the purified water/hot water/cold water discharge operation, the cooling water intake and drainage process, the hot water drainage process, etc. are described in the technical field to which the present invention pertains. Since it is only a technique clearly recognized by a person skilled in the art to which the present invention pertains, its description is omitted.

First, the extraction process of cooking water is explained. The control unit 50 is in a standby state (closing operation of the first and second water purification valves 9 and 10, closing operation of the sterilizing water drain valve 37, display unit 3) with power supplied from the power unit 1. maintains the current status display, etc.). When the user opens the cooking water lever 92a, purified water flows into the cooking water outlet (piping 90a) through the flow sensor 7, so the flow sensor 7 determines the flow rate at which purified water is flowing in (or supplied). The detection value is applied to the control unit 50, and the control unit 50 determines that the cooking water is being discharged through the supply pipe 90 based on the obtained flow rate detection value, and the user is informed that the cooking water is being discharged through the display unit 3. inform When the cooking water lever 92a is closed while cooking water is being discharged, the inflow (flow) of purified water disappears, so the control unit 50 supplies cooking water according to the flow rate detection value (no flow rate) from the flow rate sensor 7. It is confirmed that the dispensing of cooking water has been stopped, and the user is notified through the display unit (3) that the dispensing of cooking water has stopped.

Next, the process of discharging the sterilizing water is explained. When the control unit 50 obtains the sterilizing water selection input from the input unit 5 during the standby state, it controls the first water purification valve 9 to be opened. When the user operates the sterilizing water lever 92b in the open state, purified water is applied from the purified water supply unit to the hot water outlet, and the control unit 50 supplies purified water to the hot water outlet based on the flow rate detection value from the flow sensor 7. Check that it is flowing into the (sterilizing water generating section). When the inflow of purified water is confirmed (or when there is an inflow of purified water), the control unit 50 controls the sterilization drive control unit 35 to activate at least one of the first and second sterilization modules 36a and 36b. It operates to generate sterilizing water, and the generated sterilizing water is discharged through the supply pipe (90).

Next, the process of draining the sterilizing water is explained. During the discharge of the above-mentioned sterilizing water, the control unit 50 confirms the interruption of the inflow of purified water by closing the sterilizing water lever 92b through the flow rate detection value from the flow sensor 7 or stops the sterilizing water from the input unit 5. When a selection is input, the control unit 50 controls the sterilization drive control unit 35 to stop the operating first and second sterilization modules 36a and 36b, and operates the sterilizing water drain valve 37 and/or Alternatively, when the hot water drain valve 33 is operated in an open state for a certain period of time, purified water flows back into the sterilizing water outlet and the remaining sterilizing water is drained through the drain pipe to clean the sterilizing water generating unit and the sterilizing water outlet. In addition, when the selection to stop sterilizing water is input from the input unit 5, but the sterilizing water lever 92b is in the open state, the sterilizing water in the supply pipe 90 is also drained and washed by the above sterilizing water draining process.

In addition, since the sterilizing water generating unit is configured in the hot water outlet, the sterilizing water may remain in the hot water outlet (in particular, the pipes 17b and 17c) even when the sterilizing water drain valve 37 is opened. To solve this problem, the control unit 50 controls the first purified water valve 9 and the hot water drain valve 33 to be opened, so that the sterilizing water remaining in the pipes 17c and 17b flows through the hot water drain into the drain pipe. can be drained. In addition, in order to drain the sterilizing water remaining in the connection pipe 17a, the control unit 50 controls the first and second purification valves 9 and 10 and the hot water drain valve 33 to be opened. The sterilizing water remaining in the pipe 17a is drained and cleaned.

Alternatively, when the water purification device is not provided with a sterilizing water drain unit including the sterilizing water drain valve 37, that is, when the connector 75k is removed from the pipe 90b, after the sterilizing water discharge process, the control unit 50 ) opens the first purified water valve 9 and/or the second purified water valve 10 and the hot water drain valve 33 to drain the sterilized water in the sterilized water generator through the drain pipe to produce sterilized water (or hot water). The draining process of the sterilizing water can also be performed by washing a portion of the generator. At this time, the selection to stop sterilizing water is input from the input unit 5, but when the sterilizing water lever 92b is in the open state, the sterilizing water in the supply pipe 90 is also drained due to the sterilizing water draining process by the control unit 50. It is washed.

Below, the sterilizing water supply function of the water purification device is explained in more detail.

FIG. 3 is a control flowchart of the water purification device of FIG. 1.

In step S1, the control unit 50 starts standby state control. In this standby state, the first and second purification valves (9), (10), the flow control valve (11), and the sterilizing water drain valve (37) (if provided) are closed, and the first and second sterilizing modules (36a) and (36b) are in a closed state, and all valves (21, 23, 25, 29, 31, 33) are closed in relation to the function of the purified water/cold water/hot water outlet.

In step S3, the control unit 50 determines whether the sterilizing water selection input has been obtained through the input unit 5 while maintaining the standby state. If the sterilizing water selection input is obtained, the process proceeds to step S5. Otherwise, the process proceeds to step S1 and maintains the standby state.

In step S5, the control unit 50 switches the first purified water valve 9 to the open state, so that when the sterilizing water lever 92b is switched to the open state, purified water flows into the hot water outlet and the sterilizing water outlet ( supply) to create a possible state.

In step S7, the control unit 50 determines whether purified water is flowing from the purified water supply unit through the flow rate detection value from the flow rate sensor 7. In step S5, since the standby state of step S1 (components operated under the control of the control unit 50 remain closed) remains the same, only the sterilizing water lever 92b allows the introduction of purified water. Let it be done. If there is an inflow of purified water, the control unit 50 determines that the sterilizing water lever 92b has changed from the closed state to the open state. Otherwise, it determines that the sterilizing water lever 92b remains closed. If there is an inflow of purified water from the purified water supply unit, the process proceeds to step S9. Otherwise, if there is no inflow of purified water (that is, if the inflow of purified water is blocked), the control unit 50 performs step S7 for a certain period of time and then proceeds to step S11.

In step S9, the control unit 50 controls the sterilization drive control unit 35 to operate one or more of the first and second sterilization modules 36a and 36b to transform the purified water in the pipe 18d into sterilizing water. The sterilizing water outlet mode is performed by converting the sterilizing water to the sterilizing water outlet and discharging the water into the supply pipe 90. At this time, the control unit 50 maintains the sterilizing water drain valve 37 in a closed state. Additionally, the control unit 50 notifies the user visually or audibly of the discharge of sterilizing water through the display unit 3.

A more detailed execution process of the sterilizing water discharge mode is described in detail in FIG. 4.

In step S11, the control unit 50 determines that the sterilizing water lever 92b remains closed and there is no inflow of purified water, switches the first purified water valve opened in step S5 to the closed state, and performs step ( Proceed to S1) and maintain standby status.

In step S13, the control unit 50 continuously determines whether purified water is flowing from the purified water supply unit through the flow rate detection value from the flow rate sensor 7 while performing the sterilizing water discharge mode in step S9. . If there is an inflow of purified water from the purified water supply unit (for example, while the sterilizing water lever 92b remains open), the process proceeds to step S15. Otherwise, if the inflow of purified water does not occur or is stopped, the process proceeds to step S17. Proceed.

In step S15, the control unit 50 determines whether a sterilizing water stop selection input has been obtained from the input unit 5. If the sterilizing water stop selection input is obtained, the control unit 50 proceeds to step S17. Otherwise, it proceeds to step S9 and performs the sterilizing water discharge mode.

In step S17, the control unit 50 controls the first purified water valve 9, which was opened in step S5, to be changed to a closed state to stop the inflow of purified water.

In step S19, the control unit 50 stops the operating first and second sterilizing modules 36a and 36b, so that the first and second sterilizing modules 36a and (36b) are sterilized in a state where there is no inflow of purified water. 36b) prevents overheating and damage.

The sterilizing water discharge mode is terminated by the above-described steps (S17) and (S19).

In step S21, the control unit 50 performs a sterilizing water drain mode in which the sterilizing water remaining in the hot water outlet (piping 18d) and the sterilizing water outlet is drained and cleaned, and the sterilizing water drain mode is being performed. The user is guided through the display unit (3). The control unit 50 controls the first purified water valve 9 and the sterilized water drain valve 37 to be switched to the open state to drain the sterilized water into the drain pipe using purified water supplied from the purified water supply unit, 18d) and the sterilizing water outlet. In another method, the control unit 50 controls the first purification valve 9 and the hot water drain valve 33 to be opened, and the pipes 17c and 17b are The remaining sterilizing water can be drained into the drain pipe through the hot water drain.

In addition, the order of performance of steps S17 and (S19) may be changed, so that step S13 or step S15 progresses to step S19, and step S17 is performed after step S19. It may be possible.

Figure 4 is a detailed flowchart of the steps of performing the sterilizing water discharge mode in step S9 of Figure 3.

In step S51, the control unit 50 controls the sterilization drive control unit 35 and the second flow rate control valve 13 to perform the reference control mode. The reference control mode includes the operation of generating sterilizing water at medium power of the first sterilizing module 36a, stopping the operation of the second sterilizing module 36b, and opening the flow control valve 11 (i.e., the operation of the purified water flow rate control unit). A maximum flow rate supply operation of purified water through the first and second supply paths).

In step S53, the control unit 50 acquires the current value (or electrical characteristic value including the voltage value) flowing in the first sterilization module 36a from the sterilization drive control unit 35, and sets the current value and the reference value (e.g. For example, compare 0.5A). The reference value is a current value used to determine whether the concentration of sterilizing water supplied to the sterilizing water outlet has reached the desired concentration. The control unit 50 can determine the concentration of the sterilizing water based on the obtained current value. If the obtained current value is greater than the reference value, proceed to step S55, otherwise proceed to step S57.

In step S55, the control unit 50 determines that the current concentration of the sterilizing water has reached the desired concentration and reduces the power to control the sterilizing drive control unit 35 to operate the first sterilizing module 36a at minimum power. Execute control mode. Then, the control unit 50 proceeds to step S13.

In step S57, the control unit 50 determines that the current concentration of the sterilizing water does not reach the desired concentration, and changes the flow rate control valve 11 from the open state to the closed state to reduce the flow rate. (That is, the constant supply flow rate of purified water through the first supply path of the purified water flow rate controller) is performed.

In step S59, the control unit 50 obtains the current value flowing in the first sterilization module 36a from the sterilization drive control unit 35 and compares the current value with a reference value. If the obtained current value is greater than the reference value, it is determined that the current concentration of the sterilizing water has reached the desired concentration and the process proceeds to step S13. Otherwise, the process proceeds to step S61.

In step S61, the control unit 50 determines that the current concentration of the sterilizing water does not reach the desired concentration, and controls the sterilizing drive control unit 35 to operate the first sterilizing module 36a at maximum power. Perform incremental control mode. Then, the control unit 50 proceeds to step S63.

In step S63, the control unit 50 obtains the current value flowing in the first sterilization module 36a from the sterilization drive control unit 35 and compares the current value with a reference value. If the obtained current value is greater than the reference value, it is determined that the current concentration of the sterilizing water has reached the desired concentration and the process proceeds to step S13. Otherwise, the process proceeds to step S65.

In step S65, the control unit 50 controls the sterilization drive control unit 35 and the flow rate control valve 11 to perform a sterilization module increase control mode. The sterilizing module increase control mode includes simultaneous sterilizing water generation operation at medium power of the first and second sterilizing modules 36a and 36b, and opening operation of the flow rate control valve 11.

In step S67, the control unit 50 obtains the current value flowing in the first sterilization module 36a or the second sterilization module 36b from the sterilization drive control unit 35 and compares the current value with a reference value. If the obtained current value is greater than the reference value, it is determined that the current concentration of the sterilizing water has reached the desired concentration and the process proceeds to step S13. Otherwise, the process proceeds to step S69.

In step S69, the control unit 50 determines that the current concentration of the sterilizing water does not reach the desired concentration, and changes the flow rate control valve 11 from the open state to the closed state to reduce the flow rate. (That is, the constant supply flow rate of purified water through the first supply path of the purified water flow rate controller) is performed.

In step S71, the control unit 50 obtains the current value flowing in the first sterilization module 36a or the second sterilization module 36b from the sterilization drive control unit 35 and compares the current value with a reference value. If the obtained current value is greater than the reference value, it is determined that the current concentration of the sterilizing water has reached the desired concentration and the process proceeds to step S13. Otherwise, the process proceeds to step S73.

In step S73, the control unit 50 determines that the current concentration of the sterilizing water does not reach the desired concentration, and operates the sterilizing drive control unit to operate the first and second sterilizing modules 36a and 36b at maximum power. Perform power increase control mode to control (35). Then, the control unit 50 proceeds to step S13 and supplies sterilizing water while continuously adjusting the concentration of the sterilizing water if purified water is introduced in step S13 and there is no input to stop sterilizing water in step S15.

In FIG. 4 described above, the control unit 50 determines the number of sterilizing modules that perform the sterilizing water generating operation and the number of sterilizing modules based on the current value flowing through the first or second sterilizing modules 36a and 36b. By varying at least one of the size of the operating power (maximum/medium/minimum) and the flow rate passing through the sterilization module (maximum supply flow rate or constant supply flow rate), sterilizing water of a desired concentration is generated. Through this control, the control unit 50 can supply sterilizing water with a constant sterilizing concentration even if the flow rate of incoming raw water (or purified water) varies or the total dissolved solids concentration of the raw water varies.

1 to 4 described above, the sterilizing water outlet mode is implemented using the first and second sterilizing modules 36a and 36b, but only one sterilizing module (i.e., the first sterilizing module 36a) is used. It is also possible to perform a sterilizing water discharge mode by providing or using it. In FIG. 4, the control unit 50 performs steps S51 to S61 and steps S61 to S13, thereby controlling the flow rate and power of the sterilization module using one sterilization module. By doing so, the sterilization concentration can be varied.

Additionally, the control unit 50 repeatedly performs steps S51 to S73 in the sterilizing water discharge mode until the inflow of purified water continues and a selection input to stop sterilizing water is obtained.

Next, in the case of the cooking water discharging process, since the cooking water discharging unit is directly connected to the purified water supply unit through the connector 75a, when the user switches the cooking water lever 92a from the closed state to the open state, purified water from the purified water supply unit is supplied through the supply pipe ( 90), it is discharged as cooking water. While the cooking water is being dispensed, the control unit 50 maintains a standby state and uses the flow rate detection value from the flow sensor 7 to confirm that the cooking water is being dispensed through the cooking water outlet, and the display unit 3 indicates that the cooking water is being dispensed. Displays . When the user switches the cooking water lever 92b from the open state to the closed state while cooking water is being discharged, the inflow of purified water from the purified water supply unit is blocked, and the control unit 50 uses the flow rate detection value of the flow sensor 7 to purify the water. It is determined that the outflow of cooking water has ended by checking the inflow of , and the display unit 3 indicates that the outflow of cooking water has ended.

Next, the sterilization mode functions for the purified water outlet, cold water outlet, and hot water outlet are explained.

First, the process of performing sterilization mode for the hot water outlet is explained. The control unit 50 is in a standby state with power supplied from the power unit 1 (the first and second purified water valves 9 and 10, the purified water outlet valve 21, the cold water outlet valve 23, and the hot water outlet valve 25). , the closing operation of the cooling water valve 29, the cooling water drain valve 31, the hot water drain valve 33, and the sterilizing water drain valve 37, the current status display through the display unit 3, etc.). When the user inputs hot water selection (hot water outlet selection) and sterilization mode selection through the input unit 5, the control unit 50 operates the first purification valve 9 and the hot water outlet valve according to the input from the input unit 5. (25) is converted from the closed state to the open state, and the sterilizing drive control unit 35 is controlled to operate one or more of the first and second sterilizing modules 36a and 36b to generate sterilizing water, and the generated The sterilizing water is discharged through the hot water outlet and through the water outlet (70). The sterilizing water generated by the first and second sterilizing modules 36a and 36b is supplied to the hot water generator to sterilize the inside of the pipes 17c, 17b, 17d, 17e and the water outlet 70. After allowing sterilizing water to flow through the hot water outlet for a first reference time, the control unit 50 controls the sterilizing drive control unit 35 to control the operation of the first and second sterilizing modules 36a and 36b. After performing a stop and opening the first purified water valve 9 and/or the second purified water valve 10 for a second reference time to supply purified water to the hot water outlet to perform cleaning with sterilizing water in the hot water outlet, The sterilization mode is terminated by operating the first purification valve 9 and the hot water outlet valve 25 in a closed state. As described above, the control unit 50 opens the first purified water valve 9 and/or the second purified water valve 10, the hot water drain valve 33, and/or the sterilized water drain valve 37 to supply sterilized water. You can also drain the water to clean the sterilizing water generating section, hot water outlet section, and connection section.

Next, the process of performing the sterilization mode for the cold water outlet is explained. The control unit 50 maintains a standby state by supplying power from the power unit 1. When the user inputs cold water selection (selection of cold water outlet) and sterilization mode selection through the input unit 5, the control unit 50 operates the first purification valve 9 and the cold water outlet valve according to the input from the input unit 5. (23) is converted from the closed state to the open state, and the sterilizing drive control unit 35 is controlled to operate one or more of the first and second sterilizing modules 36a and 36b to generate sterilizing water, and the generated The sterilizing water is discharged from the sterilizing water generating unit, through the connection (piping 17a), through the cold water outlet, and through the water outlet 70. The sterilizing water generated by the first and second sterilizing modules 36a and 36b passes through the connection portion, the pipes 15b, 15c, and 15d, and the water outlet 70, and enters the cold water outlet (or the cold water outlet flow path). It is supplied to and sterilizes the connection and cold water outlet. After supplying sterilizing water to flow through the cold water outlet for the first reference time, the control unit 50 controls the sterilizing drive control unit 35 to control the operation of the first and second sterilizing modules 36a and 36b. After performing an operation stop and opening the first purified water valve 9 and/or the second purified water valve 10 for a second reference time to supply purified water to the cold water outlet to perform sterilizing water cleaning in the cold water outlet. The first purification valve 9 and the cold water outlet valve 23 are operated in a closed state to end the sterilization mode.

Next, the process of performing the sterilization mode for the purified water outlet is explained. The control unit 50 maintains a standby state by supplying power from the power unit 1. When the user inputs the selection of purified water (selection of the purified water outlet) and the sterilization mode selection through the input unit 5, the control unit 50 operates the first purified water valve 9 and the purified water outlet valve according to the input from the input unit 5. (21) is converted from the closed state to the open state, and the sterilization drive control unit 35 is controlled to operate one or more of the first and second sterilization modules 36a and 36b to generate sterilizing water, and the generated The sterilizing water is discharged from the sterilizing water generating unit, through the connection (piping 17a) and the piping 15a, through the purified water outlet, and through the water outlet 70. The sterilizing water produced by the first and second sterilizing modules 36a and 36b passes through the connection (piping 17a), piping 15a, piping 21a, piping 21b and outlet 70. While doing so, it is supplied to the purified water outlet (or the flow path of the purified water outlet) to sterilize the purified water outlet. After allowing sterilizing water to flow through the purified water outlet for a first reference time, the control unit 50 controls the sterilizing drive control unit 35 to control the operation of the first and second sterilizing modules 36a and 36b. After performing the stop and supplying purified water to the purified water outlet by opening the first purified water valve 9 and/or the second purified water valve 10 for a second reference time to perform cleaning with sterilizing water in the purified water outlet, The sterilization mode is terminated by operating the first purified water valve 9 and the purified water outlet valve 21 in a closed state.

The above-described sterilization mode is a process in which the control unit 50 individually sterilizes the cold water outlet, hot water outlet (and hot water drain), and purified water outlet, and the control unit 50 sterilizes the cold water outlet, hot water outlet (and hot water drain). Part), sterilization mode may be performed on at least two or more water outlets among the purified water outlets or all water outlets. For example, in order to perform the sterilization mode for all water outlets, when the user inputs the selection of the entire sterilization mode through the input unit 5, the control unit 50 performs the first sterilization mode according to the input from the input unit 5. The purified water valve 9 is opened and the sterilization drive control unit 35 is controlled to operate one or more of the first and second sterilizing modules 36a and 36b to generate sterilized water, and the purified water outlet valve 21 and , the cold water outlet valve 23, the hot water outlet valve 25 (or the hot water drain valve 33), and the flow control valve 11 are controlled to be open. At this time, the control unit 50 may also open the sterilizing water drain valve 37 to sterilize the sterilizing water outlet.

After allowing sterilizing water to flow through the cold water outlet, hot water outlet, and purified water outlet for a first reference time, the control unit 50 controls the sterilization drive control unit 35 to control the first and second sterilization modules in operation ( 36a), 36b are stopped, and the first and/or second purified water valves (9), (10), purified water outlet valve (21), cold water outlet valve (23), and hot water are discharged for a second reference time. By maintaining the open state of the water outlet valve 25 (or hot water drain valve 33) and the flow control valve 11, purified water is supplied to the cold water outlet, hot water outlet, and purified water outlet to the cold water outlet and hot water outlet. (or hot water drain), after performing sterilizing water cleaning in the purified water outlet, the first and second purified water valves (9), (10), the cold water outlet valve (23), the hot water outlet valve (25), and the flow rate The sterilization mode is terminated by operating the control valve 11 in a closed state. During this sterilizing water draining process, the control unit 50 may also open the sterilizing water drain valve 37 to allow the sterilizing water to be drained.

In the following, the sterilization mode function of the water purification device is explained in more detail.

Figure 5 is a sterilization mode control flowchart of the water purification device of Figure 1.

In step S101, the control unit 50 enters a standby state. Step S101 is the same as step S1 in FIG. 3.

In step S103, the control unit 50 determines whether a water outlet selection input has been obtained through the input unit 5 while maintaining the standby state. If the water outlet selection input is obtained, the process proceeds to step S105. Otherwise, the process proceeds to step S101. Selectable water outlets include the above-described purified water outlet, cold water outlet, and hot water outlet.

In step S105, the control unit 50 determines whether the sterilization mode selection input is obtained through the input unit 5. If the selection input of the sterilization mode is obtained, proceed to step S107, otherwise proceed to step S101.

In step S107, the control unit 50 controls the first water purification valve 9 to be in an open state and controls the sterilization drive control unit 35 to operate one of the first and second sterilization modules 36a and 36b. By operating the above, the purified water in the pipe 18d is converted into sterilizing water, and the valves included in the selected water outlet for sterilization of the selected water outlet (pure water outlet valve 21, cold water outlet valve 23, hot water outlet valve 25) The sterilization mode is performed by operating one or more of the valves (or all valves) in an open state to supply sterilizing water to the selected water outlet. Additionally, the control unit 50 visually or audibly notifies the user through the display unit 3 that the sterilization mode for the selected water outlet is being performed.

A more detailed sterilization mode implementation process is described in detail in FIG. 6.

In step S109, the control unit 50 determines whether purified water is flowing from the purified water supply unit based on the flow rate detection value from the flow rate sensor 7 while performing the sterilization mode according to step S107. If there is an inflow of purified water from the purified water supply unit, the process proceeds to step S113. Otherwise, if there is no inflow of purified water (that is, if the inflow of purified water is blocked or stopped), the control unit 50 proceeds to step S111.

In step S111, when the inflow of purified water from the purified water supply unit is stopped, there is no supply of purified water to the first and second sterilizing modules 36a and 36b, so the control unit 50 controls the sterilizing operation control unit 35 to The operation of the first and second sterilizing modules 36a and 36b is stopped to prevent the first and second sterilizing modules 36a and 36b from overheating and being damaged. Additionally, the control unit 50 notifies the user visually or audibly through the display unit 3 that the operation of the sterilization module has stopped.

In step S113, the control unit 50 obtains a selection input for stopping the sterilization mode from the input unit 5 or determines whether the time for performing the sterilization mode in step S107 has elapsed the first reference time. If the interruption selection input of the sterilization mode is obtained or the first reference time has elapsed, the control unit 50 proceeds to step S117; otherwise, the interruption selection input of the sterilization mode has not been obtained and the first reference time has not elapsed. If not, proceed to step S107 and perform sterilization mode. Here, the first reference time corresponds to the time at which sterilization of the selected water outlet and outlet can be sufficiently performed.

In step S115, the control unit 50 determines whether purified water is flowing from the purified water supply unit based on the flow rate detection value from the flow rate sensor 7 after the operation of the first and second sterilization modules 36a and 36b is stopped. judge. If the inflow of purified water from the purified water supply unit resumes within a certain period of time, the process proceeds to step S113. If the inflow of purified water from the purified water supply unit does not resume within a certain time, the process proceeds to step S121.

In step S117, the control unit 50 controls the sterilization operation control unit 35 to stop the operation of the first and second sterilization modules 36a and 36b, and a process of changing purified water into sterilizing water is performed. Instead, the purified water itself is supplied to the selected water outlet, so that the sterilized water in the sterilized water outlet is discharged or drained. Additionally, the control unit 50 visually or audibly notifies the user through the display unit 3 that the sterilization module is in operation or is being cleaned with sterilizing water.

In step S119, the control unit 50 determines whether the time after stopping the operation of the first and second sterilization modules 36a and 36b has elapsed the second reference time. The second reference time is set as a time sufficient for the sterilized water in the sterilized water outlet and outlet to be discharged or drained through the supply of purified water to clean the sterilized water outlet and the outlet. If the second reference time has elapsed, the process proceeds to step S121. Otherwise, the process proceeds to step S117 so that purified water continues to be supplied.

In step S121, the control unit 50 controls the valve of the selected water outlet (the valve operated in the open state in step S107) and the first purification valve 9 to a closed state, and then ends the sterilization mode or performs step Proceed to the standby state in (S101).

The execution order of the above-described steps (S113) and (S115) may be changed.

In addition, if the inflow of purified water is not resumed in step S115 and proceeds to step S121, the control unit 50 visually or audibly informs the user through the display unit 3 that the sterilizing water may remain in the selected water outlet. can warn you.

FIG. 6 is a detailed flowchart of the steps of performing the sterilization mode in step S107 of FIG. 3.

In step S150, the control unit 50 controls the first purified water valve 9 to be open, and the valves included in the selected water outlet for sterilization of the selected water outlet (pure water outlet valve 21, cold water outlet valve ( 23), one or more of the hot water outlet valves (25) are operated in an open state so that purified water is supplied to the selected water outlet.

Step S151 is step S51 in FIG. 4, step S153 is step S53 in FIG. 4, step S155 is step S55 in FIG. 4, and step S157 is step S51 in FIG. 4. Step S57 and step S159 are step S59 in FIG. 4, step S161 is step S61 in FIG. 4, step S163 is step S63 in FIG. 4, and step ( S165) is the step (S65) of FIG. 4, step (S167) is the step (S67) of FIG. 4, step (S169) is the step (S69) of FIG. 4, and step (S171) is the step (S67) of FIG. 4. Steps S71) and S173 are the same as step S73 in FIG. 4. However, in the case of [Yes] of steps (S159), (S163), (S167), and (S171) and in the case of step (S155), the process proceeds to step (S109) instead of step (S13) in FIG. 4.

5 to 6 described above, the sterilization mode is implemented using the first and second sterilization modules 36a and 36b, but only one sterilization module (i.e., the first sterilization module 36a) is provided. You can also use sterilization mode. In FIG. 6, the control unit 50 performs steps S151 to S161 and steps S109 from S161 to adjust the flow rate and power of the sterilization module using one sterilization module.
