The control unit 500 applies a constant voltage or a reverse voltage to the thermoelectric module 300 so that water flowing in the first flow space S1 of the instantaneous cold / hot water unit 200 is instantaneously cooled or heated by the thermoelectric module 300 Cold water or hot water.

Thus, one thermoelectric module 300 can instantaneously make cold or hot water. Accordingly, the instantaneous cold / hot water generating machine 100 and the water treatment apparatus 10 including the instantaneous water / cold water machine 100 can be miniaturized, and energy used for making cold water and hot water can be saved.

The control unit 500 may include an input unit 510. The user can select and input either a cold water mode in which cold water is generated in the instantaneous cold / hot water unit 200 through the input unit 510 of the control unit 500 or a hot water mode in which hot water is generated.

When the cold water mode or the hot water mode is input to the input unit 510, the controller 500 may first supply water to the second flow space S2 of the heat dissipation unit 400 as shown in FIG. 2 have.

For example, when the cold water mode or the hot water mode is inputted to the input unit 510, the controller 500 can open the second supply valve VF2 of the heat-absorbing cooling inlet line LI2.

The water in the raw water supply source flows into the second flow space S2 of the heat radiation cooling section 400 through the raw water supply line LS and the heat absorbing cooling intake line LI2 and flows into the second flow space S2 and drained to the outside through the heat-dissipating cooling drain line LD1.

The flow of water in the second flow space S2 of the heat radiating cooling unit 400 may continue until the cold water mode or the hot water mode is terminated.

Since the water flows into the second flow space S2 of the heat radiation cooling unit 400, the thermoelectric module 300 can be easily positioned within the operating temperature range, It can minimize the malfunction.

After allowing the water to flow into the second flow space S2 of the heat dissipation cooling unit 400, the controller 500 may apply a voltage to the thermoelectric module 300. [

For example, the control unit 500 may apply a constant voltage to the thermoelectric module 300 in the cold water mode and apply a reverse voltage to the thermoelectric module 300 in the hot water mode.

In this case, the cooling side (CS) of the thermoelectric module 300 to be cooled when the constant voltage is applied is connected to the instantaneous cold / hot water part 200 and the heat radiating part (HS) 400) are connected to each other.

The cooling side CS of the thermoelectric module 300 which is connected to the instantaneous cold / hot water portion 200 of the thermoelectric module 300 heated when the constant voltage is applied and the thermoelectric module 300 cooled when the constant voltage is applied, The cooling unit 400 may be connected.

In this case, the controller 500 applies a reverse voltage to the thermoelectric module 300 in the cold water mode and a constant voltage to the thermoelectric module 300 in the hot water mode.

The control unit 500 supplies water to the first flow space S1 of the instantaneous cold / hot water unit 200 as shown in FIG. 3 to apply the voltage to the thermoelectric module 300, .

For example, the control unit 500 opens the first supply valve VF1 and the flow control valve VC of the cold / hot water supply line LI1, and the water filtered in the filtration unit 20, that is, To the first flow space S1 of the instantaneous cold / hot water section 200 to flow through the first flow space S1.

In this way, the water can be cooled or heated by the thermoelectric module 300 while flowing in the first flow space S1 of the instantaneous cold / hot water unit 200, thereby becoming cold water or hot water.

3, the control unit 500 operates the flow path switching valve VS so that cold water or hot water flows through the cold / hot water outflow line LO, is discharged to the outside through the water outflow member 600, .

In the case where either the cold water mode or the hot water mode is first input to the input unit 510 of the control unit 500, the controller 500 controls the thermoelectric module 300 as shown in FIG. 4 A predetermined amount of water can be supplied to the first flow space S1 of the instantaneous cold / hot water unit 200 as well as the second flow space S2 of the heat dissipation cooling unit 400. [

For example, when either the cold water mode or the hot water mode is first inputted, the controller 500 controls the first supply valve VF1 of the cold / hot water supply line LI1 together with the second supply valve VF2 of the heat / ) And the flow control valve (VC).

Water can be supplied to the first flow space S1 of the instantaneous cold / hot water unit 200 as well as the second flow space S2 of the heat radiation cooling unit 400. [

The water that has flowed in the first flow space S1 of the instantaneous cold / hot water unit 200 is discharged to the cold / hot water discharge line LO as shown in FIG. 4 by the operation of the flow path switching valve VS by the control unit 500, And may be drained to the outside via the cold water outflow line LO, the outflow drain line LD2, and the heat dissipation cooling drain line LD1.

When a predetermined amount of water such as about 150 ml of water is supplied and flowed to the first flow space S1 of the instantaneous cold / hot water section 200 by the first flow sensor SF1 and measured and transmitted to the controller 500, The control unit 500 may close the first supply valve VF1 and the flow control valve VC of the cold / hot water supply line LI1.

As a result, water continues to flow in the second flow space S2 of the heat radiating cooling unit 400, and only a predetermined amount of water flows into the first flow space S1 of the instantaneous cold / hot water unit 200, do.

Accordingly, even if any one of the cold water mode and the hot water mode is first input to the input unit 510 of the controller 500, the voltage of the first space of the instantaneous cold / hot water unit 200 S1) is not empty and water may be contained.

Accordingly, the thermoelectric module 300 can be easily made to be within the operating temperature range, so that the malfunction of the thermoelectric module 300 can be minimized.

The control unit 500 applies a voltage to the thermoelectric module 300 only when the water is supplied to the second flow space S2 of the heat generation cooling unit 400 and flows into the second flow space S2, The voltage may not be applied to the thermoelectric module 300 if it is not supplied.

For example, the control unit 500 applies the voltage to the thermoelectric module 300 only when the flow rate of the water flowing through the heat release cooling intake line LI2 is measured and transmitted by the second flow rate sensor SF2, The control unit 500 may not apply a voltage to the thermoelectric module 300. [

This is because the cold water or hot water mode is input to the input unit 510 and the voltage is applied to the thermoelectric module 300 as well as the voltage is applied to the thermoelectric module 300, And the water flows to the thermoelectric module (S1) and is cooled or heated by the thermoelectric module (300).

As a result, the thermoelectric module 300 can be easily made to be within the operating temperature range, so that the malfunction of the thermoelectric module 300 can be minimized.

On the other hand, if the temperature of the water flowing through the heat-dissipating cooling drain line LD1 after flowing in the second flow space S2 of the heat-dissipating cooling unit 400 exceeds a predetermined abnormal heating temperature in the cold water mode or a predetermined abnormality When the temperature becomes lower than the cooling temperature, the controller 500 can cut off the power and stop the entire operation.

For example, when the temperature of the water flowing through the heat-dissipating cooling drain line LD1 measured by the drain temperature sensor T3 is higher than a predetermined excessive heating temperature, for example, 45 deg. C in the cold water mode or a predetermined abnormal cooling temperature When the temperature is lower than 5 占 폚, the controller 500 can cut off the power and stop the entire operation.

The temperature of the water flowing through the heat-dissipating cooling drain line LD1 after flowing in the second flow space S2 of the heat-dissipating cooling unit 400 becomes equal to or higher than the predetermined abnormal heating temperature in the cold water mode, , It may be that the thermoelectric module 300 malfunctions.

Therefore, the control unit 500 can cut off the power supply to the cold / hot water heater 100, stopping the entire operation, and protect the cold / hot water heater 100 including the thermoelectric module 300 from malfunctioning.

If the malfunction of the thermoelectric module 300 is investigated, the thermoelectric module 300 may be repaired or replaced if the thermoelectric module 300 malfunctions.

On the other hand, when water is supplied to the first flow space S1 of the instantaneous cold / hot water unit 200, the temperature difference between the water of the cold / hot water inlet line LI1 and the water of the cold / hot water line LO may be equal to or higher than a predetermined temperature difference.

In this case, hot water or cold water remains in the first flow space S1 of the instantaneous cold / hot water section 200 within a short period of time from the hot water mode to the cold water mode or from the cold water mode to the hot water mode.

In this state, it is not easy to make cold or hot water of a predetermined target temperature by cooling or heating the water flowing in the first flow space S1 of the instantaneous cold / hot water section 200 by the thermoelectric module 300, A large amount of energy is consumed in the thermoelectric module 300.

In this case, as shown in FIG. 5, the control unit 500 controls the amount of water remaining in the first flow space S1 until the temperature difference between the water of the cold inlet line LI1 and the water of the cold / hot water outlet line LO becomes less than the predetermined temperature difference, Water such as hot water or cold water can be drained through the outflow drain line LD2.

Thereby, it is possible to relatively easily and quickly make cold water or hot water at a predetermined target temperature, and relatively little energy can be consumed in the thermoelectric module 300.

For example, when the water is supplied to the first flow space S1 of the instantaneous cold / hot water unit 200, the water of the cold water inlet line LI1 measured by the water temperature sensor T1 and the water outflow temperature sensor T2, The temperature difference of the water of the cold-outgoing water line (LO) measured by the water-cooling water line (LO) may be 5 ° C or higher, for example.

In this case, the control unit 500 operates the flow path switching valve VS until the temperature difference between the water in the cold inlet line LI1 and the water in the cold / hot water outlet line LO becomes less than 5 DEG C, for example, 200 can be drained through the outflow drain line LD2.

After the water supplied to the first flow space S1 of the instantaneous cold / hot water section 200 is cooled or heated by the thermoelectric module 300 to become cold or hot water of a predetermined preliminary temperature, Water can be continuously supplied to the first flow space S1, and cold water or hot water can be discharged through the cold / outgoing water line (LO).

For example, in the cold water mode, only after the water supplied to the first flow space S1 of the instantaneous cold / hot water section 200 is cooled by the thermoelectric module 300 and reaches 9 [deg.] C close to the predetermined target temperature of 5 [ 500 may allow water to be continuously supplied to the first flow space S1.

The control unit 500 may operate the flow path switching valve VS so that cold water is discharged to the outside through the cold / hot water line LO and the water outlet valve 600 and supplied to the user.

Also, in the hot water mode, only after the water supplied to the first flow space S1 of the instantaneous cold / hot water section 200 is heated by the thermoelectric module 300 and reaches 76 deg. C adjacent to the predetermined target temperature of 80 deg. 500 may allow water to be continuously supplied to the first flow space S1.

The control unit 500 may operate the flow path switching valve VS so that hot water is discharged to the outside through the cold / hot water outflow line LO and the outflow valve 600 and supplied to the user.

The temperature of the cold water or hot water which is supplied to the first flow space S1 of the instantaneous cold / hot water section 200 and is cooled or heated by the thermoelectric module 300 is measured by the cold / cold water inlet line LI1 measured by the water temperature sensor T1. And the temperature of the cold-water outflow line (LO) measured by the out-water temperature sensor (T2).

However, the temperature of the cold water or the hot water produced in the instantaneous cold / hot water unit 200 may be directly measured by a separate temperature sensor (not shown) connected to the first flow space S1 of the instantaneous cold / hot water unit 200.

The control unit 500 adjusts the flow rate of the water flowing into the first flow space S1 of the instantaneous cold / hot water unit 200 through the cold / hot water supply line LI1 and discharges it through the cold / The temperature of the cold water or hot water may be within a desired target temperature range.

For example, the control unit 500 controls the flow rate of water flowing into the first flow space S1 of the instantaneous cold / hot water unit 200 through the cold / hot water supply line LI1 by the first flow sensor SF1 and the flow control valve VC Can be adjusted.

The temperature of the cold water or hot water discharged through the cold water outflow line (LO) and the outflow valve (600), which is measured by the outflow temperature sensor (T2), is within a desired predetermined target temperature range, 75 < 0 > C to 80 < 0 > C.

6, the controller 500 determines whether the cold or hot water in the cold / hot water outflow line (LO) is in the target outflow range or not, until the temperature of the cold / hot water in the cold / (LD2).

For example, if the temperature of the cold water or the hot water of the cold-water outflow line (LO) measured by the outflow temperature sensor T2 is not within the desired predetermined target temperature range of 5 占 폚 to 8 占 폚 or 75 占 폚 to 80 占 폚, Can operate the flow path switching valve VS to drain cold water or hot water of the cold / outgoing water line LO through the outflow drain line LD2 and the heat dissipation / cooling drain line LD1.

If the temperature of the cold water or hot water in the cold / outgoing line (LO) is within the desired predetermined target temperature range of 5 to 8 DEG C or 75 to 80 DEG C, the control unit 500 operates the flow path switching valve VS Cold water or hot water of the cold / outgoing line (LO) may be discharged to the outside through the water-discharging member (600) and supplied to the user.

The control unit 500 adjusts the flow rate of the water supplied to the first flow space S1 of the instantaneous cold / hot water unit 200 through the cold / hot water inlet line LI1, and is cooled or heated by the thermoelectric module 300, The temperature of the cold water or hot water discharged through the line (LO) can be adjusted.

For example, in the cold water mode, the target temperature of cold water may be selected and input to the user through the input unit 510 of the controller 500 at 5 ° C, 8 ° C, or 11 ° C.

The controller 500 controls the flow rates of the water supplied to the first flow space S1 through the cold inlet line LI1 by means of the first flow sensor SF1 and the flow control valve VC to 0.4 LPM Minute) or 0.45 LPM or 0.55 LPM.

Accordingly, the temperature of the cold water discharged through the cold water outflow line (LO) and the water outflow member (600) and supplied to the user can be adjusted to be the target temperature input to the input unit (510).

In this case, the power applied to the thermoelectric module 300 by the control unit 500 may be constant, for example, 1 kW.

Also, in the hot water mode, the target temperature of the hot water may be selected and input to the user through the input unit 510 of the controller 500 at 60 ° C, 70 ° C, or 80 ° C, respectively.

The control unit 500 sets the flow rates of the water supplied to the first flow space S1 through the cold inlet line LI1 by the first flow sensor SF1 and the flow control valve VC to 0.65 LPM Minute) or 0.6LPM or 0.55LPM.

Accordingly, the temperature of the hot water discharged through the cold-water outflow line (LO) and the water-discharging member (600) and supplied to the user can be adjusted to be the target temperature input to the input unit (510).

In this case, the power applied to the thermoelectric module 300 by the control unit 500 may be constant, for example, 2.2 kW.

The controller 500 controls the cooling water heated by the thermoelectric module 300 while flowing in the first flow space S1 of the instantaneous cold / hot water unit 200, And the temperature of the cold water or hot water discharged through the cold / hot water discharge line (LO) can be adjusted.

For example, the control unit 500 controls the flow rate switching valve VS to operate until the temperature of the cold water or hot water of the cold-outgoing water line LO measured at the outflow temperature controller T2 reaches the target temperature input to the input unit 510 So that cold water or hot water can be drained to the outside through the outflow drain line LD2 and the heat dissipation cooling drain line LD1.

When the temperature of the cold water or hot water of the cold / outgoing water line LO measured by the outflow temperature sensor T2 reaches the target temperature input to the input unit 510, the control unit 500 operates the flow path switching valve VS to cool the cold water Or hot water may be drained to the outside through the water outlet member 600 and supplied to the user.

In addition, the controller 500 adjusts the power applied to the thermoelectric module 300 so that the controller 500 is cooled or heated by the thermoelectric module 300 while flowing in the first flow space S1 of the instantaneous cold / hot water part 200, The temperature of the cold or hot water flowing in the line (LO) can be adjusted.

On the other hand, when the temperature of the cold water or hot water flowing through the cold-water outflow line (L0) cooled or heated by the thermoelectric module (300) while flowing in the first flow space (S1) of the instantaneous cold / The control unit 500 may not apply a voltage to the thermoelectric module 300 for a predetermined time.

For example, if the temperature of the cold water of the cold-water outflow line (LO) measured by the outflow temperature controller (T2) in the cold water mode is 2 ° C or lower, the controller 500 does not apply voltage to the thermoelectric module 300 If the temperature of the cold water in the cold outgoing line (LO) is 0.5 DEG C or less, the controller 500 may not apply the voltage to the thermoelectric module 300 for 2 seconds.

Thereby, it is possible to prevent the water flowing in the first flow space S1 of the instantaneous cold / hot water portion 200 from being excessively cooled by the thermoelectric module 300 in the cold water mode.

If the temperature of the hot water of the cold-outgoing water line (LO) measured by the outgoing water temperature sensor (T2) in the hot water mode is 93 DEG C or more, the controller 500 does not apply the voltage to the thermoelectric module 300 If the temperature of the hot water in the cold outgoing line (LO) is 96 ° C or higher, the controller 500 may not apply the voltage to the thermoelectric module 300 for 2 seconds.

Thereby, it is possible to prevent the water flowing in the first flow space S1 of the instantaneous cold / hot water section 200 from being excessively heated by the thermoelectric module 300 in the hot water mode.

On the other hand, if the hot water mode is not inputted to the input unit 510 of the controller 500 for a predetermined time after the hot water mode, the controller 500 can switch to the cold water mode.

For example, if the hot water mode is not inputted to the input unit 510 within 10 seconds after the end of the hot water mode, the controller 500 can switch to the cold water mode.

The temperature of the water flowing into the first flow space S1 of the instantaneous cold / hot water section 200 through the cold / hot water supply line LI1 may be, for example, about 15 占 폚.

The temperature of the cold water cooled by the thermoelectric module 300 while flowing in the first flow space S1 of the instantaneous cold / hot water section 200 in the cold water mode is, for example, about 5 캜. In the hot water mode, The temperature of the hot water heated by the thermoelectric module 300 while flowing in the first flow space S1 of the first thermoelectric module 200 may be, for example, about 70 ° C.

Therefore, more power must be applied to the thermoelectric module 300 in the hot water mode than in the cold water mode, so that more load is applied to the thermoelectric module 300 in the hot water mode than in the cold water mode.

Therefore, if the hot water mode is maintained even though the hot water is not used, the thermoelectric module 300 may be overloaded and the thermoelectric module 300 may malfunction or fail to operate.

Accordingly, if the hot water mode is not inputted to the input unit 510 of the control unit 500 for a predetermined time after the hot water mode is terminated, the controller 500 switches to the cold water mode, Can be prevented from malfunctioning or being prevented from being operated.

Since the controller 500 is switched to the cold water mode, when the user desires cold water, the cold water can be generated relatively quickly and supplied to the user.

7, the controller 500 controls the first flow space S1 to supply water to the first flow space S1 of the instantaneous cold / hot water portion 200 for a predetermined period of time, So that the hot water remaining in the outflow drain line LD2 can be drained.

For example, the control unit 500 can open the first supply valve VF1 and the flow control valve VC after switching to the cold water mode, and operate the flow path switching valve VS.

Water is supplied to the first flow space S1 of the instantaneous cold / hot water section 200 through the cold / hot water inlet line LI1 and flows along with the hot water remaining in the first flow space S1, And the outflow drain line LD2 and the heat-dissipating cooling drain line LD1.

After a predetermined time, for example, 2 seconds to 3 seconds, the controller 500 can close the first supply valve VF1 and the flow control valve VC to operate the flow path switching valve VS.

Accordingly, the water flowing in the first flow space S1 of the instantaneous cold / hot water unit 200 can be relatively easily and rapidly cooled or heated by the thermoelectric module 300 in the cold water mode or the hot water mode.

When the hot water mode is inputted to the input unit 510 of the control unit 500 within a predetermined time after the end of the cold water mode, the controller 500 controls the flow of the hot water in the first flow space S1 of the instantaneous cold water unit 200 as shown in FIG. Water may be supplied and flow for a predetermined time so that the cold water remaining in the first flow space S1 can be drained through the outflow drain line LD2.

For example, when the hot water mode is inputted to the input unit 510 within 10 seconds after the end of the cold water mode, the control unit 500 can open the first supply valve VF1 and the flow control valve VC and operate the flow path switching valve VS have.

Water is supplied to the first flow space S1 of the instantaneous cold / hot water portion 200 through the cold / hot water inlet line LI1 and flows along with the cold water remaining in the first flow space S1, And the outflow drain line LD2 and the heat-dissipating cooling drain line LD1.

After a predetermined time, for example, 2 seconds to 3 seconds, the controller 500 can close the first supply valve VF1 and the flow control valve VC to operate the flow path switching valve VS.

Accordingly, water flowing in the first flow space S1 of the instantaneous cold / hot water section 200 can be relatively easily and quickly heated by the thermoelectric module 300. [
