The electrolytic cell 30 comprises a cathode 32 and an anode 33 which are opposed to each other with an electrolytic film 31 in between. By applying a DC electrolysis voltage to the cathode 32 and the anode 33, the water in the electrolytic cell 30 is electrolyzed into alkaline ionized water and acidic water. That is, calcium ions, sodium ions, potassium ions, magnesium ions, and the like are collected on the cathode 32 side of the electrolytic film 31, and alkaline ionized water is generated. Sulfide ions, chlorine ions, hydroxide ions, and the like are collected on the anode 33 side of the electrolytic film 31, and acidic water is generated.

In the cooler 40, the alkaline ionized water that has flowed into the container 41 from the electrolytic cell 30 is heated by the heat pipe 4
It is cooled by 8. The cooled alkaline ionized water is appropriately taken out from a faucet (not shown).

The container 41 can store the alkaline ionized water flowing from the electrolytic cell 30. A container cover 43 is attached to the container 41. A heat radiation chamber 44 is formed inside the container cover 43, and a blower fan 45 and a heat radiation blind 46 are provided. The blower fan 45 forces the air into the heat dissipation chamber 44 to force the heat pipe 48
To cool. The heat radiating blind 46 is composed of a large number of slits, and discharges the air applied to the heat pipe 48 by the blower fan 45 into the atmosphere again. A through hole 49 is provided at a joint portion between the container 41 and the container cover 43 so as to communicate the both. The heat pipe 48 is attached to the through hole 49.

A large number of heat pipes 48 are arranged vertically with one end protruding into the container 41 and the other end protruding into the heat dissipation chamber 44. Refrigerant liquid is enclosed in the heat pipe 48. As the refrigerant liquid, ethanol, methanol, acetone, pentane, ethane and the like are preferably used. Due to the action of this refrigerant liquid, heat exchange is performed between both ends of the heat pipe 48, that is, heat exchange is performed between the alkaline ionized water and the heat radiation chamber 44, and the alkaline ionized water is cooled. The temperature of the alkaline ionized water is adjusted to be about 10 ° C. lower than the average temperature by adjusting the air volume of the blower fan 45.

The reference numeral 59 indicates a guide for efficiently guiding the alkaline ionized water flowing from the electrolytic cell 30 to the heat absorbing fins 55.

The electronic cooling element 51, as shown in FIG.
One end of each of the N-type semiconductor and the P-type semiconductor is connected with a metal such as copper (electrode C), and the electrodes A and B at the other end of each semiconductor are the anode (+) and the cathode (+) of the DC power source 57, respectively. -) Is connected and configured. In such a closed circuit, when a current flows from the N-type semiconductor in the P-type semiconductor direction (direction of arrow I), the Peltier effect causes the electrode C to absorb heat and the electrodes A and B to generate heat. A water temperature sensor 58 is connected between the DC power source 57 and the N-type semiconductor. The water temperature sensor 58 performs on / off control of the direct current flowing in the closed circuit based on the temperature of the alkaline ionized water in the container, and controls the endothermic action by the Peltier effect to adjust the water temperature.

It is adjusted to be lower in the front and back. The difference between the temperature of alkaline ionized water and room temperature is 1
When the temperature is lower than 0 ° C, the water temperature sensor 58 is turned on, and the direct current from the direct current power source 57 flows in the closed circuit. Since the direction of the electric current is in the direction of arrow I, the endothermic action due to the Peltier effect occurs in the electrode C and the electrodes A and B generate heat. The endothermic action generated in the electrode C cools the endothermic fins 55, which cools the alkaline ionized water in the container 41. When the difference between the water temperature and the room temperature becomes larger than 10 ° C, the water temperature sensor 58 is turned off and no current flows in the closed circuit. Therefore, the endothermic and exothermic effects due to the Peltier effect do not occur and the cooling of the alkaline ionized water is stopped.
