After repeating the addition of the mineral extract liquid 21 at time T ₂ to the raw water 14 under pressure at time T ₀ , the pump 39 is stopped to complete the extraction.

Next, the operation of the control section 76 will be explained with reference to the flowchart shown in FIG.

First, turn on the power switch (not shown).
As shown in step _S1 , the output of the sensor 66 is "0", that is, the light from the light emitting element 65 reaches the float 62.
If the output of the sensor 66 is "1", it is assumed that the mineral water storage container 7 has not been set or other preparations have been completed, and the process proceeds to step _S2 . The alarm lamp 68 lights up as shown, and step S ₁
Return to On the other hand, if the output of the sensor 66 is "0", it is assumed that the preparation has been completed, and as shown in step _S3 , it is determined whether or not the designated operation button 72A is on, and if it is on, the process proceeds to step _S4 . For example, display lamp 3 corresponds to the specified extraction amount as shown in
The display lamp 73D lights up when the extraction amount is specified. Next, as shown in step _S5 , it is determined whether or not the start button 71 is turned on. If it is turned on, a time count (parameter Tx) is started in step _S6 , and the pump ₃₉ is turned on in step S7.
is driven. As a result, the raw water 14 supplied from the raw water supply container 6 into the water tray 8 passes through the water suction pipe 42 via the pipe connection part 41 and is sucked into the pump 39.
The raw water 14 discharged from the pump 39 is transferred to the pipe connection part 16
The mineral-containing water is pumped from the water supply port 27 into the chamber 26 of the extraction cartridge 5, passes through the activated carbon layer 28, the ion exchange resin layer 29, and the ceramic layer 30 in sequence, and is sent into the chamber 26A from the communication port 34, containing minerals. It passes through the stone layer 32 and the fiber layer 33 and is purified by removing dirt and gases such as chlorine, methane, captan, etc., lime, iron, manganese, etc. contained in the raw water 14 by the activated carbon layer 28, the fiber layer 33, etc. ,
and an ion exchange resin layer 29, a ceramic layer 30,
The minerals contained in the mineral-containing stone layer 32 and the like are dissolved and extracted as mineral water 18, which is then discharged from the outlet 46 through the mineral water outlet pipe 45 via the pipe connection part 19 and the extraction hole 69A.
The water is stored in the mineral water storage container 7 via the mineral water storage container 7. In this way, as shown in step _S8 , the output of the sensor 66 becomes "1", that is, the set amount (0.5
) is stored in the mineral water storage container 7 and the float 62 floats, so that the light from the light emitting element 65 reaches the light receiving element 65.
It continues to be determined whether or not light is received by A. The amount is set in the mineral water storage container 7.
When 0.5 of the mineral water 18 is stored, the output of the sensor 66 becomes "1", and as shown in step _S9 , the measured time Tx at the time when the output of the sensor 66 becomes "1" is stored as _T0 in the memory 79. .
Next, in step _S10 , it is determined whether _T0 is greater than or equal to a preset allowable time _T1 ,
If T ₀ ≧ T ₁ , it is assumed that it is time to replace the extraction cartridge 5, and the display lamp 75 is turned on in step _S11 , and then the process moves to step _S12 .
On the other hand, if T ₀ <T ₁ , the process directly proceeds to step _S12 . Further, as shown in step _S12 , the extraction amount designated by the extraction amount designation means 72 is 3.
The time T required for extraction is calculated as 3/0.5×T ₀ and this calculation time T is stored in the memory 79. Next, a time count (parameter Ty) is started in step _S13 , and a time count (parameter Tz) is started in step _S14 .
Furthermore, the pump 48 is driven in step _S15 .
As a result, the mineral extract liquid 21 supplied from the mineral extract liquid supply container 35 into the saucer 22 passes through the mineral extract liquid outlet pipe 52 and is added to the raw water 14 in the water tray 8 from the outlet 53, and the process proceeds to step _S16.
In step S17, it is determined whether or not the measured time Ty has reached the preset addition time _T2 of the mineral extract liquid 21, and when the measured time Ty reaches _T2 , the pump 48 is stopped in step _S17 . Addition of mineral extract liquid 21 is stopped. Then step
As shown in _S18 , it is determined whether or not the measured time Tz has reached _T0 , and if the measured time Tz has reached _T0 , the extraction amount 3 specified by the measured time Tx is determined in step _S19 . A judgment is made as to whether or not the time T until storage has been reached, and if Tx has not reached T, the routine moves to a routine that follows "NO" in step _S19 , returns to step _S13 , and steps _S13 to S By repeating the process ₁₉ and adding the mineral extract liquid 21 at time T ₂ to the amount of raw water 14 fed at time T ₀ , the highly pure mineral water 18 to which the mineral extract liquid 21 has been added continues to be extracted. In this way, when the measured time Tx reaches T, the step
At _S20 , the pump 39 is stopped, the designated extraction amount of mineral water 18 is stored in the mineral water storage container 7, and the extraction is completed.

In this way, in the above embodiment, the sensor 6 detects that a preset amount of mineral water 18 has been extracted within a range smaller than the minimum extraction amount designated by the extraction amount designation means 72.
6, the time T 0 from the start of extraction until the sensor 66 detects that the set amount of extraction is completed is measured by the clock means ₇₈ , and the current extraction cartridge is determined based on the measured time T ₀ and the set amount. Based on this extraction speed, the calculation processing means 82 calculates the time T until the extraction amount designated by the extraction amount designation means 72 is obtained, and during this calculated time T. Since it is configured to drive the pump 39, there is no need to keep pressing the switch button until the extraction is finished as in the conventional case, and the desired extraction amount can be accurately obtained by simply turning on the designated operation button 72A and the start button 71. be able to. Further, as mentioned above, the drive time T of the pump 39
The extraction speed determined from a preset amount value and the time _T0 during which extraction of this set amount is performed, that is, the current degree of deterioration of the extraction cartridge 5 or variation in the discharge amount of the pump 39, is determined. The desired amount of extraction can be obtained accurately. Further, the extraction amount specifying means 72 is easy to operate because the plurality of display lamps 73, 73A, 73B, 73C, and 73D are displayed cyclically by pressing a single specifying operation button 72A. Further, the sensor 66 is configured to detect the movement of the float 62 in the float chamber 60 provided in the mineral water storage container 7 based on whether or not the light from the light emitting element 65 is received by the light receiving element 65A. becomes a simple and inexpensive device. Furthermore, since a trace amount of mineral extract liquid 21 is added to the raw water 14, mineral water 18 with a high mineral content can be extracted regardless of the quality of the raw water 14. Further, in the above embodiment, the display lamp 73D corresponding to the extraction amount, for example, 3, specified by the extraction amount specifying means 72 is configured to be lit continuously at the specified time, blinked during extraction, and continuously lit after extraction. For example, if the specified extraction amount is 3
The indicator lamp 73 lights up in 1, the indicator lamp 73A lights up in 1.5, and the indicator lamp 7 lights up in 2, depending on the extraction amount at the elapsed time until reaching the extraction amount.
The extraction progress state may be displayed by sequentially lighting up the lights such as 3B. Also, the 13th
As shown in the figure, five indicator lamps 7 are displayed during extraction.
3, 73A, 73B, 73C, and 73D may be repeatedly displayed in a cyclical manner. Also, when the raw water 14 is out of water detected by the float switch 10, all the display lamps 7 are turned off as shown in FIG.
