Referring to FIG. 13, the water taking-out process according to the operation of the dispenser will be described as follows.

First, the water supplied from the water supply source 1 can be supplied to the filter device 40 through the water supply channel 61. At this time, the water supply to the filter device 40 can be determined by the water supply valve 612 provided on the water supply channel 61. A flow rate sensor 613 is provided on the water supply channel 61 so that a specified amount of water can be taken out by using the flow rate detected by the flow rate sensor 613 when the dispenser 20 is operated. The flow rate sensor 613 is capable of measuring the flow rate of water passing through the water supply flow path 61, and may be of a magnetic type or a hole sensor type.

The water introduced into the filter device 40 is purified by the filter 42 and the purified water in the filter device 40 passes through the purified water flow path 62 and the hinge 16 to the dispenser 20 . A purified water flow path 62 branched from the water purification valve 622 extends to the connecting member 662 of the dispenser 20 and the ice making flow path 64 extend to the ice maker 30. That is, the water purification valve 622 operates according to the user's manipulation to control the supply of the purified water to the dispenser 20 or the icemaker 30.

That is, when it is sensed that the water of the set capacity is taken out through the flow rate sensor 613, the water purifying valve 622 is closed without any operation, and the taking out of the purified water is completed.

That is, when an integer is selected using the constant input unit, the water purification valve is opened and the cold water valve is closed. In this state, when the water is taken out by the amount of water set by using the takeoff amount input unit, the water purification valve is closed. On the other hand, when cold water is selected through the cold water input unit, the cold water valve is opened and the water purification valve is closed. At this time, whether or not to take out the amount of water described using the take-out amount input unit can be judged based on the flow rate sensed by the flow rate sensor 613.

If a certain amount of purified water is taken out in a state where the pushing operation of the push pad 13 is detected, if the pushing operation of the push pad 13 is not detected before a predetermined amount of purified water is taken out, The water purification valve may be closed to interrupt.

When a certain amount of purified water is taken out in a state in which the pushing operation of the push pad 13 is detected, after a predetermined amount of purified water is taken out, The water purification valve may be closed to stop the extraction. That is, even if the pushing operation of the push pad 13 is continuously sensed after the certain amount of purified water is taken out, the water purification valve is closed.
