First, the water stop state will be described. As shown in FIG. 2A, the holes 22, 23, 2 provided in the unit portion 12
Since the balls 4 are blocked by the balls 30, 31 and 32, respectively, even if the pressurized water reaches the unit portion 12 from the water flow pipe 13, the water flow does not occur. See also FIG.
As shown in (b), the convex portion of the cam 38 is located in the groove provided in the switch portion 39.

Next, the state of purified water is shown in FIGS. 3 and 4 (a) (b).
Will be explained. From the water stopped state, the motor 34 is driven to rotate the switching valve 25 so that the convex portion of the cam 38 approaches the switch portion 41. Then, when the convex portion of the cam 38 pushes the switch portion 41, the motor 34 stops, and the switching valve 25 stands still with the convex portion of the cam 38 pushing the switch portion 41. Then, as shown in FIG. 4A, the balls 30 and 32 move from above the holes 22 and 24, respectively, to open the holes 22 and 24, respectively. The water pressurized as described above passes through the running water pipe 13 and the unit portion 1

At this time, since the packing 33 is provided, the water flowing into the unit portion 12 from the water flow pipe 13 and the water flowing into the unit portion 12 from the filter medium container 8 are not mixed. The purified water that has flowed into the unit portion 12 is discharged to the outside through the hole 24 and the water pipe 14. When ending the purified water state, a predetermined operation is performed to drive the motor 34 and rotate the switching valve 25 so that the convex portion of the cam 38 approaches the switch portion 39. When the convex portion of the cam 38 acts on the switch portion 39, the motor 3
No. 4 stops rotating and enters a water-stop state as shown in FIG.

Impurities and the like adsorbed on the activated carbon 9 are removed. Then, the inside of the filter medium container 8 is kept at a predetermined temperature (in this embodiment, about 65 ° C., but may be any temperature as long as impurities and the like can be removed from the activated carbon 9) for a predetermined time (30 minutes to 60 in this embodiment).
After heating, the motor 34 is driven from the water stop state to switch the switching valve 25 so that the convex portion of the cam 38 approaches the switch portion 40 after heating. Rotate towards the end. Then, when the convex portion of the cam 38 presses the switch portion 40, the motor 34 stops, and the switching valve 25 stands still with the convex portion of the cam 38 pressing the switch portion 40. Then Fig. 6
As shown in (a), the ball 31 moves from above the hole 23,
The hole 23 is opened. Since the pressurized water reaches the unit portion 12 via the running water pipe 13, the water flows into the filter medium container 8 from the hole 22 through the water pipe 15 by opening the hole 23. Then, the hot water (water containing impurities and the like) after washing the activated carbon 9 is driven to the upper surface of the filter medium container 8 by the water flowing from the water pipe 15, and is drained from the water pipe 18 through the horizontal valve portion 17. It Water pipe 1 for a predetermined time
After pouring water from 5 into the filter medium container 8, a predetermined operation is performed to drive the motor 34 and the switching valve 25 to the cam 3.

Is provided. Reference numeral 59 is a motor drive circuit which drives the motor 34 and is controlled by the microcomputer 58, and 60 is a heater drive circuit which drives the heating heater 10 and is controlled by the microcomputer 58 and the temperature detector 11. The heater drive circuit 60 includes the microcomputer 58 and the temperature detector 11
The reason for controlling by both of the above is that if the microcomputer 58 runs away while the heater 10 is generating heat, it will continue to be heated even if the temperature inside the filter medium container 8 exceeds a predetermined temperature. Since the device is damaged due to heat, the heater driving circuit 6 is also affected by the temperature detector 11.
0 control is performed. That is, when the temperature detector 11 detects a temperature equal to or higher than a predetermined temperature, the operation of the heater driving circuit 60 is stopped separately from the microcomputer 58 to prevent abnormal heating in the filter medium container 8.

The operation of the control system configured as follows will be described with reference to FIG. First, when the device is powered on, the microcomputer 58 first determines the current position of the switching valve 25 from the outputs from the switch parts 39, 40 and 41.
After that, the device returns to the power failure recovery state, and the time portion of the display unit 46 starts to light up. Then, as described above, the button of the operation unit 47 is pressed to set the current time. After the setting is completed, if the switching valve 25 is not in the water-stopped state, the microcomputer 58 sends a signal to the motor drive circuit 59 to drive the motor 34, so that the switching valve 25 is in the water-stopped state as shown in FIG. Rotate to position. Further, when the heating of the filter medium container 8 and the drainage of the hot water in the filter medium container 8 are set to one cycle, this is set to one to several cycles (in this embodiment, N times). Further, the heat retention time of the filter medium container 8 at this time is also set in advance. Such processing is performed before the operation of STEP (hereinafter abbreviated as S) 1 is started. When the operation starts in S1, first, in S2, the key scan of the button of the operation unit 47 is performed. In S2, the processing as shown in FIG. 11 is performed. First, ON / OFF of the motor 34 is controlled in S3, and the display unit 46 is controlled in S4. Then stop water at S5
The button of the operation unit 47 for water purification, heat cleaning, heat cleaning time setting, etc. is scanned to make a determination. After that, in S6, the switching valve 2
The output of the switch parts 39, 40, 41 is scanned for the current position of No. 5. When the key scan process of S2 is completed in this way, the mode switching of S7 is performed next. The mode switching is performed as shown in FIG. First, in S8, it is determined whether or not the button of the operation unit 47 has been pressed. That is, it is determined whether or not there is a button pressed when the button of the operation unit 47 is scanned in S5. When any button is pressed, it is determined in S9 whether the pressed button is the water stop operation button 49 or not. If the pressed button is the water stop operation button 49, the water stop mode is set in S10, and the process returns to S7. If the pressed button is not the water stop operation button, the flow advances to S11 to determine whether the pressed button is the water purification operation button 50. If the pressed button is the water purification operation button 50, the process proceeds to S12, the water purification mode is set, and the process returns to S7. When the pressed button is not the water purification operation button 50, the process proceeds to S13, and it is determined whether the pressed button is the manual heat cleaning operation button 51. If the pressed button is the manual heat cleaning operation button 51, the process proceeds to S14, where the heat cleaning mode and the heat retention mode are set, and the process returns to S7. If the pressed button is not the manual heat cleaning operation button 51, the process proceeds to S15, and it is determined whether the pressed button is the heat cleaning time setting operation button 52. If the pressed button is the operation button 52 for setting the heat cleaning time, the process proceeds to S16, and it is determined whether the current heat cleaning mode is set. If in heat cleaning mode, proceed to S17,
Set the water stop mode and return to S7. If the heat cleaning mode is not set in S16, the process proceeds to S18, the heat cleaning time setting mode is set, and the process returns to S7. If the button pressed in S15 is not the operation button 52 for setting the heat cleaning time, the process returns to S7. If the button of the operation unit 47 has not been pressed in S8, the process proceeds to S19, in which it is determined whether the heat cleaning set time has come.

At the heat cleaning set time, the heat cleaning mode of S14 is set, and the process returns to S7. If the heat cleaning set time is not reached in S19, the process returns to S7. When the process of S7 is completed, the process proceeds to S20, and it is determined whether or not the water stop mode is set. If it is not set to the water stop mode, the process of FIG. 13 is performed. In S21, it is determined whether or not the mode is set to the water purification mode. If the water purification mode is set, the process proceeds to S22. If the heater 10 is in the heating state, the microcomputer 58 causes the heater drive circuit 6 to operate.
A signal is sent to 0 to stop energizing the heater 10. Next, in S23, it is determined whether or not the switching valve 25 is at the water purification position (that is, whether or not the switching valve 25 is located at the position shown in FIG. 3).
The microcomputer 58 makes a determination by looking at the outputs from 0 and 41. At this time, if the switching valve 25 has not reached the clean water position,
In S24, the microcomputer sends a signal to the motor drive circuit 59 to drive the motor 34, move the switching valve 25 to the water purification position, and then return between S1 and S2. If the switching valve 25 is at the water purification position in S23, the microcomputer 58 sends a signal to the motor drive circuit 59 in S25 to stop the drive of the motor 34, and then returns between S1 and S2. If the mode is not set to the water purification mode in S21, the process proceeds to the process of FIG. In S26, it is determined whether or not the mode is set to the heat cleaning mode. If it is not set to the heat cleaning mode, the process proceeds to S27. In S27, it is determined whether or not the mode is set to the heat cleaning time setting mode, and if it is set in the heat cleaning time setting mode, the process proceeds to S28, and the time for heat cleaning by the operation button of the operation unit 47 is set as described above. Set. Then, after that, the process returns between S1 and S2.
If the heat cleaning time setting mode is not set in S27, the process returns to between S1 and S2. If the heat cleaning mode is set in S26, the process proceeds to S29 and if the heater 10 is not energized, the microcomputer 58 causes the heater drive circuit 6 to operate.
A signal is sent to 0, and the heater 10 is energized to heat the inside of the filter medium container 8. Next, in S30, it is determined whether or not the heat retention mode is set, and if it is set, the process proceeds to the process shown in FIG. In S31, it is determined whether the switching valve 25 is in the water shut-off position as shown in FIG.
The microcomputer 58 judges based on the outputs of 40 and 41, and if it is at the water stop position, the process proceeds to S32. In S32, the microcomputer 58 sends a signal to the motor drive circuit 59, and the motor 3
4 is driven and the switching valve 25 is rotated. After that, the process returns between S1 and S2. If the position of the switching valve 25 is the water stop position in S31, the process proceeds to S33, and if the motor 34 is driven in S33, the microcomputer 58 outputs a signal to the motor drive circuit 59 to stop the drive of the motor 34. . After that, in S34, the energizing time of the heater 10
That is, the heat retention time of the filter medium container 8 is counted. Then S
The heat retention time preset in 35 is compared with the heat retention time counted in S34, and if the time is over, the process proceeds to S36. If not, the process returns between S1 and S2. In S36, the heat retention time is set again, and then S3
Switch the heat retention mode to the drainage mode in 7 and press S1 and S2.
Return in between. If the heat retention mode is not set in S30, the process proceeds to S38, in which the microcomputer 58 determines whether the switching valve 25 is in the drainage position as shown in FIG. 5 based on the output from the switch parts 39, 40, 41. If it is determined that the switching valve 25 is not in the drainage position, the process proceeds to S39.
In S39, the microcomputer 58 outputs a signal to the motor drive circuit 59 to drive the motor 34, and the switching valve 25
To the drain position. Next, in S40, the time for draining the water in the filter medium container 8, that is, the drainage time is set to a predetermined time, and then the process returns to between S1 and S2. If the switching valve 25 is at the drainage position in S38, the process proceeds to S41. If the motor 34 is being driven in S41, the microcomputer 58 sends a signal to the motor drive circuit 59, and the motor 3
The drive of 4 is stopped. After that, the process proceeds to S42, the preset number of cycles is compared with the present number of cycles, and when the present cycle reaches the preset number of cycles, the process proceeds to S43, and the present number of cycles is reset to zero. And S
At 44, the thermal cleaning mode is switched to the water stop mode, the cleaning interruption mode is set, and then the process returns to between S1 and S2. If the current cycle number is less than the preset cycle number in S42, the process proceeds to S45 to count the current drainage time. Then, the drainage time set in S40 is compared with the current drainage time. If the time is not over, the process returns to between S1 and S2, and if not, the process proceeds to S47. In S47, the drainage mode is switched to the heat retention mode, the cycle number is further incremented by 1 in S48, and the process returns between S1 and S2.

If the water stop mode is set in S20, the process proceeds to S49. In S49, if the heater 10 is energized, the microcomputer 58 outputs a signal to the heater driving circuit 60 to stop the energization of the heater 10. Then, the process proceeds to S50, it is determined whether the heat cleaning mode is set, and if it is set, the process of FIG. 16 is performed. S5
