Accordingly, the cooling drive means 655 drives the power control relay of the thermoelectric cooling element 262 under the control of the control means 625 to turn on the thermoelectric cooling element 262, so that the output voltage of the power supply means 600 is increased. It is applied to the thermoelectric cooling element 262, the fan motor driving means 660 drives the fan motor 241 under the control of the control means 625.

When a current is applied by applying power to the thermoelectric cooling element 262, one side of the thermoelectric cooling element 262 is an electronic cooling method using 'heat absorption' and 'heating' phenomena appearing at the contact portion of the thermoelectric cooling element 262. The heat sink 265 in contact with the other side of the thermoelectric cooling element 262 dissipates heat from the purified water stored in the cold water tank 220 in the clad sink 491 in contact with the heat sink. Cooling the purified water of the cold water container 220, at this time by the fan 242 is rotated in accordance with the drive of the fan motor 241 to release the heat radiated to the outside to improve the cooling efficiency.

At this time, the cold water temperature of the cold water tank 220 is lowered by the electronic cooling method of the thermoelectric cooling element 262 in the cold water temperature sensing means 615, the control means 625 is the cold water temperature sensing means 615 By comparing the cold water temperature sensed by) with a predetermined cold water target temperature to control the on / off operation of the thermoelectric cooling element 262 to maintain the cold water temperature of the cold water tank 220 at the target temperature.

Meanwhile, in order to heat the purified water stored in the hot water tank 160, the control means 625 outputs a control signal for driving the heater 667 to the heater driving means 665 to drive the heater 667.

When the heater 667 is driven, the purified water of the hot water tank 160 is heated by the heat of the heater 667 is changed to hot water, at this time, the hot water tank 160 rising by the heat of the heater 667 The hot water temperature Th of the hot water temperature detecting means 620, and the control means 625 compares the hot water temperature detected by the hot water temperature detecting means 620 with a preset hot water target temperature to heater 667. The hot water temperature is maintained at the hot water target temperature while controlling the on / off operation of.

On the other hand, even during the cooling and heating of the purified water in the cold water tank 220 and the hot water tank 160, the water purification operation is continuously performed until the water level in the water purification tank 130 reaches the full water level.

As described above, when the water level of the purified water container 130, which is changed during the generation of cold and hot water according to the water purification operation, is sensed by the water level detecting means 605 and outputs the detected water level data to the control means 625, the control means 625. ), It is determined whether the water level of the purified water container 130 sensed by the water level detecting means 605 is more than full water level.

When the water level of the purified water container 130 is above the full water level, the control means 625 supplies a control signal for closing the water supply valve 646 so as to stop the supply of purified water to the purified water container 130. Output to

Therefore, the water supply valve driving means 645 shuts off the power supply voltage applied to the water supply valve 646 under the control of the control means 625 to close the water supply valve 646.

When the water supply valve 646 is closed, the control means 625 outputs a control signal for stopping the pressure pump 200 to the pressure pump driving means 635 to cut off the power voltage applied to the pressure pump 200. So it presses the pressure pump 200.

When the water supply valve 646 is closed and the pressure pump 200 is stopped, the supply of raw water supplied from the tap water is cut off so that the purified water is no longer supplied into the water purification tank 130 and stops the water purification operation.

Purified water, cold water or hot water of a predetermined capacity is stored in the purified water container 130, the cold water container 220, and the hot water container 160 according to the purified water, cooling and heating operations as described above. Since the 160 is installed adjacently, heat from the hot water of the hot water tank 160 is conducted to the purified water container 130, so that the temperature of the purified water in the purified water container 130 is increased.

Accordingly, when the purified water temperature of the collection container 130 is detected by the purified water temperature sensing means 617, the control means 625 is a predetermined temperature preset water temperature detected by the purified water temperature sensing means 617. Judge whether it is abnormal.

If the purified water temperature of the purified water container 130 is greater than or equal to a predetermined temperature, the control means 625 is a circulation pump to circulate the cold water of the cold water container 220 to the purified water container 130 to lower the water temperature of the purified water container 130. The control signal for driving 430 is output to the circulation pump driving means (640).

Accordingly, the circulation pump driving means 640 receives the control signal output from the control means 625 and supplies the power voltage applied to the circulation pump 430 to drive the circulation pump 430.

When the circulating pump 430 is driven, the cold water of the cold water container 220 flows out through the cold water outlet pipe 450, and the cold water that flows out through the cold water outlet pipe 450 passes through the cold water inflow pipe 460. Since the water is introduced into the purified water container 130 and diluted with the water slightly raised, the water in the whole purified water container 130 is lowered below a predetermined temperature.

Therefore, when the purified water temperature sensing means 617 detects the lowered purified water temperature of the purified water container 130, the control means 625 is a predetermined temperature in which the purified water temperature detected by the purified water temperature sensing means 617 is preset. It judges whether it is below.

If the purified water temperature of the purified water container 130 is less than or equal to a predetermined temperature, since the cold water of the cold water container 220 does not have to be circulated to the purified water container 130, the control means 625 controls to stop the circulation pump 430. Since the signal is output to the circulation pump driving means 640 to cut off the power voltage applied to the circulation pump 430, the circulation pump 430 is stopped.

When the circulation pump 430 is stopped, the cold water of the cold water container 220 is not introduced into the purified water container 130, so that the purified water temperature in the purified water container 130 rises again, so that the control means according to the changing water temperature at this time 625 controls the operation of the circulation pump 430 to maintain the water temperature of the purified water tank 130 at an appropriate temperature.

According to the water circulation device of the water distributor according to the present invention as described above, when the mercury in the purified water tank rises above a predetermined temperature, the cold water in the cold water tank is circulated to the collection tank so that the mercury in the purified water tank due to the heat conduction of the hot water tank.
