- the outer case 76 has a larger diameter than the inner case 77. Therefore, as shown in Fig. 9, the outer case 76 is externally fitted to the inner case 77 while being attached to the base portion 75. In other words, the inner case 77 is housed inside. In this state, an equal distance in the radial direction is provided between the inner peripheral surface of the outer case 76 and the outer peripheral surface of the inner case 77.

That is, in the sand filter 22 and the activated carbon filter 23, a gap is formed in the upper portion of the inner case 77 (see the broken arrow in the figure). Note that the above-described mesh of the cap 83 that is externally fitted to each inner case 77 is set to have a lower strength than sand and activated carbon. Therefore, the sand and activated carbon S loaded in each inner case 77 and the inner case 77 will not leak.
- the sand filter 22 water that passes through the inner case 77 loaded with sand is collected by the sand. Thus, iron and manganese components solidified by oxidation are captured. If this sand is manganese sand, it is possible to capture unsolidified iron and manganese components.
- the activated carbon filter 23 the water passing through the inner case 77 loaded with activated carbon captures organic substances such as humic acid remaining in the water that has passed through the sand filter 22 by the activated carbon.

- each inner case 77 that captures foreign matters is vertically long (longitudinal) and allows water to pass in the longitudinal direction. Therefore, in the inner case 77, for example, compared to the case where water is allowed to pass in the horizontal direction, The water passage distance can be lengthened, and foreign matter capture efficiency can be increased. Then, by making the inner case 77 vertically long, the above-described catching member is overlapped in the height direction so as to provide a gap above it, and is loaded with the force S.
- the upstream switching valve 33, the midstream switching valve 34, and the downstream switching valve 35 are opened, and the sand filter 22 and the activated carbon filter 23 are drained.

Grasp the inner case 77 exposed to the outside The case 77 is removed from the case support portion 79 (see FIG. 8), and the inner case 77 is shaken, for example, immersed in water. As a result, the capture member in each inner case 77 is agitated using the gap (see the broken line arrow in FIG. 9) provided in advance in the loaded state, and the adhered foreign matter is removed.
- the outer case 76 is detached from the inner case 77 so that the inner case 77 is exposed and can be easily accessed, so that the filter 5 can be easily maintained. .
- each inner case 77 of the filter 5 is loaded with sand or activated carbon in an amount corresponding to 1/10 to 3/4 of the longitudinal dimension thereof, so that the above-described gap is captured by the capture member. It can be formed in a size suitable for good stirring. Therefore, when the entire inner case 77 is shaken during maintenance, the foreign matter captured by the capture member is effectively removed, and the performance of the capture member can be easily and satisfactorily restored. Further, by restoring the performance of the capture member by shaking the entire inner case 77, so-called backwashing (removing foreign matter from the capture member by causing water to flow backward in the inner case 77) becomes unnecessary and reverse.
- the water purification apparatus 1 can be simply configured without the configuration for washing.
- the inner case 77 and the outer case 76 are attached to the base portion 75 in the reverse procedure of the above-described removal.
- the outer case 76 is attached to the inner case 77 attached to the base portion 75 from above.
- the outer case 76 since the filter 5 is disposed on the front side of the purification device 4, the outer case 76, which is obstructed by the obstacle, is disposed above the filter 5 with respect to the inner case 77 from above. It can be attached and detached smoothly.

- the control unit 43 includes an operation panel 20, an ozone generator 42, a pump 6, a water leak sensor 70, a pressure sensor 37, and a power switch 21. Each is electrically connected.
- the operation panel 20 is provided with a power LED 95, an ozone LED 96, an abnormality LED 97, and various buttons as described above for performing various displays for the user.
- the control unit 43 controls the ozone generator 42 to generate ozone, and the pump 6 is driven to move inside the water purifier 1. Water flows. As a result, ozone is mixed with the water flowing through the water purification apparatus 1, and the water purification operation is performed.
- the power LED 95 and the ozone LED 96 are turned on to notify the user that the purification operation is being performed.
- the abnormal LED 97 is lit to notify the user that maintenance of the filter 5 is urged.
- FIG. 11 is a flowchart of control related to detection of clogging of the filter 5.
- the foreign matter trapping performance is deteriorated due to the adhesion of foreign matters to the sand and activated carbon loaded in the sand filter 22 and the activated carbon filter 23, respectively.
- clogging force S is generated in the sand filter 22 and the activated carbon filter 23 due to the adhered foreign matter.
- the flow rate (circulation flow rate) of the water circulating between the water purification device 1 and the water storage tank 3 decreases.
- control unit 43 performs the clogging detection control described below (see FIG. 10 together with FIG. 11).
- the clogging detection control is performed in synchronization with the operation control of the water purification device 1.
- the control unit 43 first resets the measurement data of the timer 93 (step S1). Then, the control unit 43 drives (ON) the pump 6 and operates (ON) the ozone generator 42 to perform the water purification operation (step S2). If the water pressure in the upstream pipe 24 (between the pump 6 and the filter 5) detected by the pressure sensor 37 is less than the predetermined upper limit ( (Step S3 YES), the control unit 43 continues the purification operation. On the other hand, when the above-mentioned water pressure increases and reaches the upper limit value (NO in step S3), the control unit 43 performs time measurement using the timer 93 (step S4).
- control unit 43 stops (OFF) the drive of the pump 6 and the operation of the ozone generator 42 to stop the purification operation (step S5). Since water stops flowing in the water purification apparatus 1 due to the stop of the purification operation, the water pressure that has risen in the upstream pipe 24 gradually decreases. If this water pressure does not drop to the predetermined lower limit (NO in step S6), the control unit 43 continues to monitor the water pressure with the purification operation stopped. On the other hand, when the water pressure reaches the lower limit value (YES in step S6), the control unit 43 stops time measurement by the timer 93 when the water pressure reaches the lower limit value (step S7).
- Step S8 YES
- the controller 43 determines that the filter 5 force S is clogged, turns on the error LED 97, and turns off the power switch 21 (Step S9). Thereby, the operation of the entire water purification apparatus 1 is stopped. Even in this state, the abnormal LED 97 is continuously lit.
- step S8 the control unit 43 stores information in the RAM 92 that the purification operation has been stopped once (step S10). Then, the control unit 43 refers to the RAM 92, and determines that the filter 5 force S is clogged if the cumulative number of the purification operation cancellations reaches the predetermined number within the predetermined period (NO in step S11). Perform step S9. This cumulative count is reset when filter 5 is maintained. On the other hand, if the cumulative number does not reach the predetermined number (YES in step S11), the control unit 43 determines that the filter 5 force S is not clogged and the water pressure reaches the lower limit value.
- the system waits for a predetermined delay time and maintains the state where the purification operation is stopped (step S12). Then, after the delay time has elapsed, the control unit 43 returns to step S 1 and continues the clogging detection control. This also restarts the purification operation.
- control unit 43 stops driving the pump 6 when the pressure reaches the upper limit value, the pressure of water can be prevented from further rising beyond the upper limit value, and the safety of the apparatus Power S can be improved. Further, when the control unit 43 determines that the filter 5 is clogged, the control unit 43 stops the operation of the entire water purification device 1, so that the safety of the device is ensured and the filter 5 is reliably notified to the user. can do.
- the control unit 43 restarts the driving of the pump 6 after a predetermined delay time elapses when the pressure of the water decreases to the lower limit value. Even without using the buffer tank 38, chattering of the pump 6 at the time of restart can be prevented only by such microcomputer control. Therefore, the force S can be used to easily configure the water purification device 1.
- the control unit 43 determines that the filter 5 is clogged and operates the entire water purification device 1. Since it is possible to effectively use the filter 5 while eliminating the waste of replacing the filter 5 that is still ready for use at an early stage, it is possible to improve the safety of the device. Monkey.
- the control unit 43 estimates the circulation flow rate of the water flowing between the water purification device 1 and the water storage tank 3 according to the elapsed time, and when resuming the purification operation, the control unit 43 sets the estimated circulation flow rate to the estimated circulation flow rate. Accordingly, the ozone generation amount of the ozone generator 42 is changed. Specifically, when the circulating flow rate is low, the flow rate of water in the ozone mixer 44 is also low, so the mixing efficiency of the ozone into the water by the ozone mixer 44 decreases. Therefore, the control unit 43 increases the ozone generation amount or extends the operation time (ozone generation time) of the ozone generator 42 in order to compensate for the decrease in mixing efficiency. As a means for increasing the ozone generation amount or extending the ozone generation time, for example, by increasing the duty ratio applied to the electrode plate (not shown) of the ozone generator 42 described above, Increase discharge
- the circulation flow rate can be easily adjusted using the elapsed time described above without using a complicated configuration. If the circulating flow rate is low, the ozone generation rate can be increased, or the ozone generation time can be extended by extending the ozone generation time. The purification efficiency can be easily suppressed from changing according to the circulation flow rate, and the water purification performance of the water purification device 1 can be maintained constant.
- the circulating flow rate may be estimated according to the cumulative number of times of the purification operation cancellation within the predetermined period. This makes it possible to easily estimate the circulation flow rate using the number of times of stopping the pump 6 described above without using a complicated configuration, as with the elapsed time, and the water purification efficiency depends on the circulation flow rate. Fluctuation can be easily suppressed, and the water purification performance of the water purification device 1 can be maintained constant.
- the actual circulating flow rate may be detected using a flow rate sensor (not shown).
- the circulation flow rate can be obtained accurately, and the water purification efficiency of the water purification device 1 can be kept constant and the water purification efficiency of the water purification device 1 can be kept constant. Monkey.
- the ozone generator 42 since the ozone generator 42 generates ozone by discharging an electrode plate (not shown) as described above, when the humidity around the ozone generator 42 increases, the electrode plate becomes damp. Ozone generation efficiency is reduced by taking on. That is, it can be said that the humidity around the ozone generator 42 affects the ozone generation efficiency, that is, the water purification efficiency. Therefore, the water purification device 1 is provided with a humidity sensor (not shown) that detects the humidity around the ozone generator 42, and the control unit 43 is around the ozone generator 42 detected by the humidity sensor (not shown). The ozone generation amount or operating time (ozone generation time) of the ozone generator 42 is changed according to the humidity of the ozone generator.
- the control unit 43 uses a means such as an increase in the duty ratio as described above. Increase the output of the generator 42 or extend the ozone generation time. In this way, it is possible to reliably suppress the fluctuation of the water purification efficiency according to the ozone generation efficiency of the ozone generator 42 using the humidity sensor and to maintain the water purification performance of the water purification apparatus 1 constant. it can.
