2 is a control block diagram of the water purification apparatus of FIG.

The water purification apparatus includes a power supply unit 1 that receives external commercial power and supplies a necessary voltage to the user, and a power supply unit 1 that supplies the user with various information (water / hot / cold water selection, sterilization water / kitchen water selection, sterilization water, (Water / hot / cold water selection, water / hot / cold water termination, sterilization / cooking water selection, sterilization water selection, etc.) from the user The first and second flow control valves 11 and 13, the cold water unit 15, the hot water supply unit 15, A water outlet valve 21, a cold water outlet valve 23, and a cold water outlet valve 23.

In the present specification, the operations of generating hot water / cold water and draining hot water are not limited to the techniques described in the related art, And the description thereof is omitted.

First, the process of taking an integer is explained. The control unit 50 acquires an integer selection input from the input unit 5 and operates only the first supply valve 9 and the second supply valve 45 and the purified water outlet valve 21 from the closed state to the open state So that the integer from the integer generating unit is allowed to flow out through the outlet port 70. Thereafter, the control unit 50 acquires the water outlet end input from the input unit 5, operates the first supply valve 9 and the second supply valve 45 from the open state to the closed state, The water outlet valve 21 is operated from the open state to the closed state after the shutoff and the constant waiting time (for example, 0.5 second) to prevent the pressure in the water outlet portion from being generated. If the difference between the closing operation time of the first supply valve 9 and the second supply valve 45 and the closing operation time of the water outlet valve 21 is large, a residue may be generated in the outlet port 70, The time is determined as the time to prevent the generation of pressure in the water purification and sterilizing water supply portion and the water outlet portion while preventing the generation of water in the outlet 70. In addition, since the pressure in the purified water and sterilization water supply section can be applied to the first and second sterilization modules 36a and 36b, the control section 50 can switch the water supply and sterilization water drain valve 37 from the closed state to the open state And maintains the open state for a predetermined period of time (for example, one second), thereby performing a pressure removal mode for reducing the pressure in the purified water and sterilizing water supply portion. After the control unit 50 performs the pressure control mode, the control unit 50 operates the water supply and drain valve 37 in the closed state.

The control unit 50 operates the cold water outlet valve 23 and the hot water outlet valve 25 in place of the water outlet valve 21 so as to cool the cold water and the hot water, And hot water outflow process. In addition, the control unit 50 controls the first flow rate control valve 11 to control the supply of purified water through the first and second supply paths during the hot water outflow process. In addition, the control unit 50 controls the water and the sterilization water drain valve 37 to perform the pressure removal mode after the cold water and the hot water are dispensed, as in the case of the water dispensation process.

Next, the outgoing process of the cooking water is explained. The control unit 50 controls the supply of the power from the power supply unit 1 to the standby state (the closing operation of the first supply valve 9 and the second supply valve 45, the closing operation of the second flow control valve 13, A closing operation of the sterilizing water drain valve 37, a current status display through the display unit 3, and the like). When the user operates the supply pipe lever 92 to open the purified water, purified water from the purified water generating portion is supplied to the cooking water through the pipe 7a, the connection port 75a and the pipe 90e, and the connection port 75m, the pipe 90f, Through the connecting port 75n and the supply pipe 90. The control unit 50 confirms that the purified water is supplied to the flow rate sensing channel by opening the cooking water lever 92 using the flow rate sensing value from the flow rate sensor 7 and then the first supply valve 9 and the second flow rate The control valve 13 is controlled from the closed state to the open state so that sufficient cooking water is supplied to the supply pipe 90. Thereafter, when the user operates the cockle lever 92 from the open state to the closed state, the purified water from the purified water generating section is no longer supplied to the purified water and sterilizing water supply section and the flow rate sensing flow path portion, The first supply valve 9 and the second flow regulating valve 13 are connected to each other through the flow rate sensor 7 after the lever 92 is closed by confirming that the purified water is not supplied to the flow rate sensing passage, And is controlled from the open state to the closed state. The control unit 50 switches the water supply and sterilization water drain valve 37 from the closed state to the open state to remove the pressure to the first and second sterilizing modules 36a and 36b in the purified water and sterilizing water supply unit Sterilizing water supply portion, the water in the cooking water and sterilizing water receiving portion, and the flow sensing passage portion are drained for a predetermined time (for example, one second), and the water and sterilization water drain valve 37 is opened To close the cooking water dispensing process.

Next, the process of dispensing sterile water is described. The control unit 50 obtains the flow rate sensing value that the purified water flows into the flow rate sensing channel from the flow sensor 7 by the opening operation of the supply pipe lever 92 during the waiting state in the cooking water discharging process, The control unit 50 controls the first supply valve 9 and the second flow control valve 13 from the closed state to the open state and controls the sterilizing drive control unit 35 And the second sterilization modules 36a and 36b to generate sterilized water, and the generated sterilized water is supplied to the cooking water and the sterilization water discharge part, and is discharged through the supply pipe 90. The control unit 50 confirms the interruption of the inflow of the purified water due to the closing of the supply pipe lever 92 through the flow rate sensed value from the flow rate sensor 7 during the outgoing of the sterilized water described above, The controller 50 controls the sterilizing drive controller 35 to stop the first sterilizing module 36a and the second sterilizing module 36b in operation and the first supply valve 9 to the closing operation Thereby terminating the sterilization water supply process.

Next, the drainage process of sterilized water is explained. The control unit 50 operates the sterilizing water drain valve 37 and the first supply valve 9 from the closed state to the open state for a predetermined time (for example, 15 seconds) The purified water is supplied to the purified water and sterilization water supply unit, the cooking water, the sterilization water discharge unit, and the flow rate sensing channel to drain the remaining sterilized water through the drain pipe. The purified water, sterilization water supply unit, And sterilizing water remaining in the supply pipe 90 is washed so that the sterilizing water is not supplied to the cooking water or contained in the cooking water at the time of supplying the cooking water. The control unit 50 controls the first supply valve 9 and the second flow control valve 13 from the open state to the closed state for the termination of the sterilized water drainage process. The control unit 50 controls the first and second flow regulating valves 13 and 13 to remove the pressure to the first sterilization module 36a and the second sterilization module 36b in the sterilization water supply unit. Sterilizing water discharge valve 37 and the sterilizing water discharge valve 37 after the closing operation of the electrolytic sterilizing water discharge valve 37 and the electrolytic sterilizing water discharge valve 37 are closed for a predetermined time (for example, 1 second) And discharges the sterilizing water by discharging the pressure of the purified water and the sterilizing water drain valve 37 from the opened state to the closed state.

In order to continuously carry out the sterilization water supply process and the sterilization water drainage process, the control unit 50 controls the flow sensor 7 to stop the inflow of the purified water by closing the supply pipe lever 92 during the outflow of the sterilized water described above, The control unit 50 controls the sterilizing drive control unit 35 to select the first sterilization module 36a and the second sterilization module 36a in operation, The sterilizing water is discharged from the closed state to the open state while the first supply valve 9 is kept open and the sterilizing water drain valve 37 is controlled from the closed state to the open state, .

In the following, the function of the water purification apparatus will be described in more detail.

In this standby state, the first supply valve 9, the second flow control valve 13, the water supply and sterilization water drain valve 37 are closed, and the first and second sterilization The operation of the modules 36a and 36b is stopped, and the second supply valve 45 is in the closed state with respect to the function of the purified / cold / hot water outlet portion.

In step S3, the control unit 50 determines whether the sterilizing number selection input is acquired through the input unit 5 while maintaining the standby state. If the sterilization number selection input is obtained, the process proceeds to step S5, otherwise the process proceeds to step S9.

In step S5, the control unit 50 determines whether a constant is flowing from the constant generating unit to the flow sensing channel through the flow sensing value from the flow sensor 7. Only the opening operation of the supply pipe lever 92 is released from the opening of the flow sensing oil passage 92 since the standby state of the step S1 in the step S5 Thereby enabling the inflow of the constants to the subdivision. By using this point, the control unit 50 determines that the supply pipe lever 92 is changed from the closed state to the open state when there is an inflow of the purified water, otherwise the supply pipe lever 92 is kept closed . That is, when the flow rate sensing value of the flow rate sensor 7 is 0, the flow of constant or raw water is stopped (the supply pipe lever 92 is closed). If the flow rate sensing value is not 0, (The state in which the supply pipe lever 92 is opened). If there is an inflow of an integer in the integer generating unit, the flow proceeds to step S7. The control unit 50 performs step S5 for a predetermined period of time and then proceeds to step S1 to select the sterilization number selection input in step S3 .

In step S7, the controller 50 operates the first supply valve 9 from the closed state to the open state and controls the sterilizing drive control section 35 so that the first and second sterilizing modules 36a, 36b To convert the purified water in the pipe 9a into sterilized water to supply the sterilized water to the cooking water and the sterilization water discharge unit to discharge the sterilized water to the supply pipe 90. At this time, the controller 50 keeps the sterilizing water drain valve 37 in the closed state. Further, the control unit 50 informs the user visually or audibly through the display unit 3 of the sterilization water.

 The process of performing a more detailed sterilization drawer mode is described in detail in FIG.

In step S9, the control unit 50 determines whether a constant is flowing from the constant generating unit to the flow rate sensing channel through the flow sensing value from the flow sensor 7. If an integer has been input in the integer generating unit, the process proceeds to step S11, and if not, the process proceeds to step S1.

The control unit 50 operates the first supply valve 9 from the closed state to the open state and controls the sterilizing drive control unit 35 to be in the open state because the control unit 50 is not the sterilization number selection input in step S3. So that the first sterilization module 36a and the second sterilization module 36b are kept in the operation stop state, thereby performing the cooking water outgoing mode. Further, the control unit 50 informs the user visually or audibly through the display unit 3 of the water outflow.

In step S13, the control unit 50 determines whether the sterilizing water selection input is obtained through the input unit 5 during the cooking water outgoing mode of step S11. If there is no sterilization number selection input, the process proceeds to step S15. Otherwise, if there is a sterilization number selection input, the process proceeds to step S7 even during the cooking water outflow mode.

In step S15, the controller 50 converts the second flow control valve 13 from the closed state to the open state to increase the flow rate to increase the supply amount of the cooking water. The process proceeds from step S15 to step S16.

In step S16, the control unit 50 determines whether the purified water is flowing from the purified water generating unit to the flow sensing channel unit or the purified water and sterilizing water supply unit through the flow sensing value from the flow sensor 7. If an integer has been input in the integer generating unit, the process proceeds to step S11, and if not, the process proceeds to step S17.

The control unit 50 determines that the first supply valve 9 and the second flow control valve 13 are in the open state to the closed state in the step S17 since the supply pipe lever 92 is changed from the open state to the closed state, And ends the cooking water outgoing mode. Further, the control unit 50 notifies the user visually or audibly through the display unit 3 of the end of the cooking water outgoing mode.

In step S18, the control unit 50 sets the cooking water and the sterilizing water drain valve 37 in the closed state (i.e., closed state) to remove the pressure to the first and second sterilizing modules 36a, 36b in the purified water and sterilizing water supply unit Sterilizing water supply portion, the water in the cooking water and sterilizing water discharge portion, and the flow rate sensing passage portion for a predetermined time (for example, one second) and discharging the purified water and the sterilizing water drain valve 37, Is operated from the open state to the closed state to perform the pressure removal mode. Then, after performing the pressure removal mode, the process proceeds to step S1.

In step S19, the control unit 50 determines whether the flow rate sensing unit 10 is in the sterilization / discharging mode of step S7 or not, through the flow sensing value from the flow sensor 7, It is judged whether or not the constant is being introduced into. If there is an inflow of an integer in the integer generating unit, the process proceeds to step S25; otherwise, the process proceeds to step S21.

In step S21, the control unit 50 does not receive the purified water from the purified water generating unit and does not supply the purified water to the purified water and sterilizing water supply unit and the flow rate sensing flow path unit. Therefore, the control unit 50 controls the sterilizing operation control unit 35 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 being overheated and damaged, 9 and the second flow control valve 13 in the closed state to terminate the sterilization water withdrawing mode. In addition, the control unit 50 informs the user visually or audibly through the display unit 3 of the end of the sterilizing water supply mode.

In step S23, the controller 50 operates the first supply valve 9 and the sterilizing water drain valve 37 in an open state so that purified water is supplied from the purified water generating section to the purified water and sterilized water supply section, Sterilizing water supply portion, cooking water and sterilizing water supply portion, flow sensing flow path portion, sterilizing water which is drained and washed through sterilized water remaining in the supply pipe (90) through a drain pipe Perform drain mode. That is, the control unit 50 supplies the purified water for a predetermined time (for example, 15 seconds) so that the sterilized water can be completely drained so that the sterilized water supply unit, the cooking water and the sterilizing water supply unit, (90). Through the sterilization water drainage and cleaning, the user is prevented from using the sterilization water remaining in the water purification and sterilization water supply portion, the cooking water and sterilization water supply portion, the flow sensing channel portion, and the supply pipe 90 as cooking water. In the sterilized water drain mode, the controller 50 keeps the second flow control valve 13 in the open state or switches it from the closed state to the open state to allow sterilization water drainage and cleaning in the second water and sterilization water supply path. In addition, the control unit 50 informs the user visually or audibly through the display unit 3 of the sterilized water multiples. Thereafter, the controller 50 operates the first supply valve 9 and the second flow control valve 13 in the closed state, and then, the first and second sterilization modules 36a, And the sterilizing water drain valve 37 is closed after a certain period of time (for example, 1 second) to remove the pressure to the pressurized water 36a and 36b. Then, the control unit 50 terminates the control process after performing the pressure removal, or proceeds to step S1.

In step S25, the control unit 50 determines whether it has acquired the disinfecting water stop selection input from the input unit 5. [ If the disinfecting water stop selection input is obtained, the control unit 50 proceeds to step S27, otherwise proceeds to step S7 to perform the sterilization water discharge mode.

In step S27, the control unit 50 determines whether the purified water is flowing from the purified water generating unit to the flow sensing flow path, the purified water, and the sterilizing water supply unit, based on the flow sensing value from the flow sensor 7. If there is an inflow of an integer in the integer generating unit, the flow advances to step (S1) or (S3).

The reference control mode includes an operation of opening the first supply valve 9, a sterilization number generating operation to the intermediate power of the first sterilization module 36a, an operation interruption of the second sterilization module 36b, (I.e., the maximum flow rate supply operation of the sterilized water through the first and second water supply and sterilization water supply paths in the cooking water and sterilization water flow rate regulating section) of the valve 13.

In step S53, the controller 50 acquires a current value (or an electrical characteristic value including a voltage value) flowing in the first sterilizing module 36a from the sterilizing drive control unit 35, For example, 0.5 A). The reference value is a constant value and a current value for determining that the concentration of the sterilizing water generated in the sterilizing water supply portion has reached the desired concentration. The control unit 50 can determine the concentration of sterilized water based on the obtained current value. If the obtained current value is larger than the reference value, the process proceeds to step S55, and if not, the process proceeds to step S57.

In step S55, the controller 50 determines that the concentration of the current sterilization water has reached the desired concentration, and controls the sterilization drive controller 35 to operate the first sterilization module 36a with the minimum power, And performs the control mode. Then, the control unit 50 proceeds to step S19.

In step S57, the control unit 50 determines that the concentration of the sterilized water does not reach the desired concentration, converts the second flow control valve 13 from the open state to the closed state to reduce the flow rate The control mode (i.e., the constant flow rate supply of the cooking water and sterilization water flow rate regulator - the flow rate supply only through the first water supply and sterilization water supply path).

In step S59, the control unit 50 obtains the current value flowing in the first sterilizing module 36a from the sterilizing drive control unit 35, and compares the current value with the reference value. If the obtained current value is larger than the reference value, it is determined that the concentration of the current sterilization water has reached the desired concentration, and the process proceeds to step S19; otherwise, the process proceeds to step S61.

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

In step S63, the control unit 50 acquires the current value flowing in the first sterilizing module 36a from the sterilizing drive control unit 35, and compares the current value with the reference value. If the obtained current value is larger than the reference value, it is determined that the concentration of the current sterilization water has reached the desired concentration, and the process proceeds to step S19, otherwise, the process proceeds to step S65.

In step S65, the control unit 50 controls the sterilizing drive control unit 35 and the second flow control valve 13 to perform the sterilization module increase control mode. The sterilization module increase control mode includes a simultaneous sterilization number generating operation to the intermediate power of the first and second sterilization modules 36a and 36b and an opening operation of the second flow control valve 13. [

In step S67, the control unit 50 acquires the current value flowing in the first sterilizing module 36a or the second sterilizing module 36b from the sterilizing drive control unit 35, and compares the current value with the reference value. If the obtained current value is larger than the reference value, it is determined that the concentration of the current sterilization water has reached the desired concentration, and the process proceeds to step S19; otherwise, the process proceeds to step S69.

In step S69, the controller 50 determines that the concentration of the sterilizing water does not reach the desired concentration, and converts the second flow control valve 13 from the open state to the closed state to reduce the flow rate The control mode (i.e., the constant flow rate supply of the cooking water and sterilization water flow rate regulator - the flow rate supply only through the first water supply and sterilization water supply path).

In step S71, the control unit 50 acquires the current value flowing in the first sterilizing module 36a or the second sterilizing module 36b from the sterilizing drive control unit 35, and compares the current value with the reference value. If the obtained current value is larger than the reference value, it is determined that the concentration of the current sterilization water has reached the desired concentration, and the process proceeds to step S19, otherwise, the process proceeds to step S73.

In step S73, the controller 50 determines that the concentration of the current sterilization water does not reach the desired concentration, and controls the first and second sterilization modules 36a and 36b to operate at maximum power. (35). ≪ / RTI > Then, the controller 50 proceeds to step S19 to supply the sterilizing water while controlling the concentration of the sterilizing water continuously in the absence of the sterilizing water stop selection input at step S25 in step S19 .

4, the control unit 50 determines the number of sterilizing modules performing the sterilizing water generating operation based on the current value flowing in the first or second sterilizing modules 36a and 36b, At least one of the magnitude of the operating power (maximum / intermediate / minimum) and the flow rate through the sterilizing module (the maximum flow rate supply or the constant flow rate supply) is varied to produce sterilized water at a desired concentration. With this control, the control unit 50 can supply sterilized water having a constant sterilization concentration, even if the flow rate of the raw water (or constant water) is variable or the total dissolved solids concentration of the raw water is varied.

In the above-described Figs. 1 to 4, when the sterilizing water receiving mode is implemented using the first and second sterilizing modules 36a and 36b, or when only one sterilizing module (i.e., the first sterilizing module 36a) Or may be used to perform the sterilization water withdrawing mode. 4, the control unit 50 performs steps S51 to S61, and performs step S19 in step S61 to adjust the flow rate and sterilizing module power using one sterilization module The sterilization concentration can be varied.

In addition, the control unit 50 repeatedly performs the steps S51 to S73 until the inflow of the constant is continued and the disinfecting water stop selection input is obtained.
