In another embodiment, the extraction amount setting means 40 is configured to set a first extraction amount which is an extraction amount of water contained in any one of the plurality of tanks 14, 16, 18 and a second extraction amount that is an extraction amount of water contained in another tank. The memory unit M may be configured to store extraction patterns relating to the first extraction amount and the second extraction amount. Through this, it is also possible to store the extraction amount of water of different temperatures at once and then to be extracted according to this pattern.

For example, if you want to extract 2/3 cup of cold water and 1/3 cup of normal temperature water, select the setting button (SB) and press the cold water tank button 20 to extract the cold water as much as you want to extract. Then, press the purified water tank button 22 to extract the normal temperature water by the amount to be extracted. After the extraction is completed according to the desired extraction pattern, pressing the memory button MB for a long time to complete the memory setting, the memory of the extraction pattern is made in the memory unit (M). Thereafter, when the user selects the pattern extraction button 26 and presses the extraction means 32 to discharge the desired extraction pattern, the controller C controls the valve V3 associated with the cold water tank 18 to be set. Cold water extraction by the amount is made, and again controls the valve (V1) associated with the purified water tank 14 to be extracted by the set amount of room temperature water. On the contrary, the control unit C simultaneously opens the valve V3 associated with the cold water tank 18 and the valve V1 associated with the normal temperature tank 14, so that the cold water and the normal temperature water are mixed at the connection part 34. It may be discharged to enable the extraction of the mixed water.
