Description

  The present invention relates to a water treatment apparatus including water treatment means such as a water purifier or an alkali ion water conditioner for treating raw water such as waterworks.

  For example, a water purifier often incorporates a cartridge-type water purifier having a filter medium that removes residual chlorine, trihalomethane, and the like in raw water, and a hollow fiber membrane filter that removes bacteria and impurities. Such a water purifying means needs to be periodically replaced with a new one because its function gradually decreases with the treatment of raw water. Therefore, for the purpose of determining the replacement time of the water purification means, a measuring means for measuring the total use time of the water purification means and a notification means for notifying that the use time has exceeded a preset set value. A water treatment device is also being developed.

  In such a water treatment apparatus, when the water purification means is replaced with a new one, it is necessary to reset the use time measured so far. Conventionally, a reset switch for performing such a reset is often provided in the vicinity of water purification means installed under a sink of a sink when the water treatment apparatus is for a kitchen, for example.

  However, when a reset switch is provided at such a position, not only is it difficult to operate, but it is also necessary to perform electrical wiring to the reset switch under the sink. There was also a problem that the storage space below was narrow and complicated.

Therefore, for example, in Patent Document 1, in an automatic faucet with a water purification function for controlling raw water and water discharge water, based on human body detection by a raw water sensor and a water purification sensor, on the upper surface of the tip of the water discharge pipe. There has been disclosed an invention that simplifies the apparatus configuration and reduces the cost by providing a raw water sensor and a water purification sensor and also using these sensors as a reset operation unit. In this automatic faucet, the usage time is reset by holding a hand over the raw water sensor for a predetermined time and then holding the hand over the water purification sensor for a predetermined time. .

  However, as in the automatic faucet described in Patent Document 1, after holding the hand over the raw water sensor for a predetermined time or more and then holding the hand over the water purification sensor for a predetermined time or more, it is easy to make an erroneous operation. There was a risk that the usage time was reset unexpectedly. Moreover, in the automatic faucet of patent document 1, the sensor for raw water and the sensor for water purification are arrange | positioned in the conspicuous position called the upper surface of the front-end | tip part of a water discharge pipe, and the design property was not favorable.

A water supply pipe 5 for supplying raw water and a water purification pipe 6 for sending purified water (treated water) from the water purifier 7 to the dedicated faucet 10 are provided. The code | symbol 2 in the figure shows the branch stopper provided in the middle of the water supply channel a.
In the present embodiment, the general faucet 20 and the dedicated faucet 10 are mounted on a sink 30 that is a base, and other members are accommodated under the sink 30. The water supply pipe 5 and the water purification pipe 6 are composed of flexible pipes that can be bent and bent, and are provided for the convenience of piping.

  The water purification means detachably mounted in the water purifier 7 is, for example, a water purification cartridge comprising a filter medium that removes and adsorbs residual chlorine and total trihalomethane in raw water, a hollow fiber membrane that removes general bacteria and impurities, and the like. However, in addition to the original filtering function for removing such harmful components, it may further have a function of tasting water or releasing components that are considered to be healthy.

  The water supply pipe 5 is provided with a constant flow valve 3 that controls the flow rate of the raw water supplied to the water purifier 7 to be constant. In addition, the water supply pipe 5 between the constant flow valve 3 and the water purifier 7 is provided with a control device 4 having an electromagnetic valve (open / close valve) for opening and closing the water supply pipe 5.

  As shown in FIGS. 2 and 3, the dedicated faucet 10 includes a columnar (outside view) faucet body 41, and a water discharge pipe 42 that extends from the peripheral surface of the faucet body 41 to the faucet body 41. And is configured. The water discharge pipe 42 is not fixed to the faucet body 41, and has a tubular casing part 42 b that rotates around a part of the circumferential direction around the axis P of the faucet body 41, and a proximal end part of the tubular casing part 42 b. And a pipe portion 42a for discharging treated water. Specifically, the tubular casing portion 42b has a tubular projecting portion 42c that opens obliquely upward, and the opening of the projecting portion 42c is liquid-tightly connected to the tube portion 42a, and the tube portion 42a and the tubular casing portion 42b are connected to each other. The inside communicates. Further, since the water discharge pipe 42 is rotatable in a part in the circumferential direction, the water purification discharge port 11 at the tip of the pipe portion 42a also moves within this range, and the position of the water discharge can be changed. Yes. The purified water treated by the water purification means is introduced into the faucet body 41 through the water purification pipe 6 and then discharged from the water purification outlet 11 at the tip of the pipe portion 42a.

  In addition, the water treatment apparatus includes operation means for switching between water discharge and water stop from the purified water discharge port 11 by controlling opening and closing of the electromagnetic valve, and the operation means of this example is provided on the upper surface of the faucet body 41. A contact switch 43 such as a tact switch (registered trademark) provided. When the contact-type switch 43 is pushed and operated, an electric signal is sent to the electromagnetic valve of the control device 4, thereby controlling the opening and closing of the electromagnetic valve. When the solenoid valve is closed, the purified water discharge port 11 is in a water stop state, and when the solenoid valve is opened, the purified water discharge port 11 is in a water discharge state.

  The water treatment apparatus of this embodiment has a management means for managing the usage time of the water treatment apparatus. In order to determine the replacement timing of the water purification means, the management means of this example is used as the accumulated time of the solenoid valve opening time, that is, the accumulated value of the discharge time of the purified water, and the usage period of the water purification means, that is, It manages the elapsed time from the start of using the new water purification means, and as a management means for measuring these usage times, a device that counts the integrated value of the opening time of the solenoid valve (hereinafter referred to as an opening time counter). The control device 4 has a built-in device for counting the usage period of the water purification means (hereinafter referred to as a usage time counter).

  Moreover, the management means of the control device 4 of this example can set in advance the threshold value of the integrated value of the open time and the threshold value of the use period of the water purification means, and either one of them can do so. When the threshold value is exceeded, it is provided with an informing means for informing it. In this example, a cartridge replacement sign 13 that informs the replacement timing of the water purifying means is provided on the upper surface of the faucet body 41 of the dedicated faucet 10 and is electrically connected to the control device 4 as the notification means. Therefore, when either one of the above exceeds the threshold value, a signal is sent to the cartridge exchange sign 13. In this example, a fresh water sign 16 for notifying that the water is suitable for drinking is also provided on the upper surface of the faucet body 41 as a notification means. The fresh water sign 16 is usually turned on immediately when the solenoid valve is in an open state, is turned off immediately when the solenoid valve is in a closed state, and is continuously turned on while clean water is discharged. Then, after the continuation time of the closed state of the solenoid valve reaches a predetermined time, when the contact type switch 43 is operated to open the solenoid valve, the fresh water sign 16 is turned on after a predetermined time has elapsed from the start of water discharge. It is configured. That is, after the water staying inside the water purification means, the water purification pipe 6 and the like is discharged from the water purification outlet 11, the light is turned on to inform that the water is suitable for drinking.

In addition, the management means of this example is provided with a reset mechanism for resetting the usage time, and when the water purification means is newly installed or replaced with a new one, the open time counter and the usage time counter are each counted. It can be reset.
In this example, the water discharge pipe 42 that is rotatable in a part in the circumferential direction around the axis P of the faucet body 41 is a magnet switch, and the contact switch 43 provided on the upper surface of the faucet body 41 is pushed. The reset mechanism is actuated by sensing the rotation of the water discharge pipe 42 performed simultaneously with this operation or within a fixed time before and after this operation. Hereinafter, a mode in which the reset mechanism is actuated by rotating the water discharge pipe 42 first to enter the reset mode and operating the contact type switch 43 after the rotation will be described.
In the present specification, “within a certain time before and after operation” is appropriately set according to the size and application of the water treatment apparatus according to the present invention, based on the time when the contact switch 43 is operated. is there. For example, when the water treatment apparatus according to the present invention is in the form of a faucet-integrated water purification apparatus or a water conditioner used in a home kitchen, in consideration of the user's sensory convenience, the contact type switch With reference to the time point when 43 is operated, it is preferably set to any one of the ranges within 5 to 30 seconds before and after that.

  Specifically, as shown in FIG. 2, the faucet body 41 of this example has an inner casing 44 that is tubular and has an inner space 44a that has an upper end and a lower end that are open and penetrates in the length direction. Outside the inner casing 44, an inner casing 44 and a tubular outer casing 45 provided in a liquid-tight manner are provided. The outer casing 45 includes an upper casing 45 a that forms an outer wall at the top of the faucet body 41, and a lower casing 45 b that is positioned below the upper casing 45 a and fixed to the inner casing 44 via the tubular casing portion 42 b. It has become.

  The upper casing 45a is configured to include a cylindrical portion 46a and a lid portion 46b fitted into the upper end of the cylindrical portion 46a in a liquid-tight manner, and the cylindrical portion 46a is screwed to the upper end of the inner casing 44 so that the inner casing 44 is engaged. Is detachably attached. Moreover, the cover part 46b comprises the upper surface part of the faucet main body 41, and the contact-type switch 43 is provided here. Therefore, when the contact type switch 43 provided on the lid portion 46b of the upper casing 45a needs to be replaced with a new one after a certain number of operations, the upper casing 45a is easily removed, The contact type switch 43 provided on the lid 46b can be exchanged. A base 47 is fixed in the upper casing 45a, and the base 47 and the contact switch 43 are electrically connected.

4 (a) to 4 (c), a protrusion (hereinafter referred to as a magnet protrusion) 48 having a magnet is provided on the inner peripheral surface of the upper end of the tubular casing portion 42b. When the water discharge pipe 42 is rotated, the magnet projection 48 is also rotated. On the other hand, on the outer peripheral surface in the vicinity of the upper end of the inner casing 44, a groove portion D that engages with the magnet protrusion 48 has a part in the circumferential direction (in this example, the central angle α is about 120 ° when the axis P is the center). The Hall IC 47a electrically connected to the substrate 47 is installed at one end in the length direction (circumferential direction) of the groove D.
Therefore, when the water discharge pipe 42 is rotated, the magnet projection 48 also moves in the groove D along the length direction of the groove D within the range of the central angle α. As shown in FIG. 4C, when the magnet projection 48 comes into contact with the Hall IC 47a installed at one end of the groove D, an electrical signal is sent from the base 47 to the control device 4 through a signal wiring (not shown). The reset mode is configured to be resettable.

Specifically, it is not necessary to reset the counts of the opening time counter and the usage time counter. In a so-called normal time, the water discharge pipe 42 is appropriately rotated so that, for example, as shown in FIG. It is positioned so as to be located at the other end of the groove D (the end on the side where the Hall IC 47a is not installed) or at a portion other than both ends of the groove D as shown in FIG. . On the other hand, when it becomes necessary to reset the counts of the opening time counter and the usage time counter, as shown in FIG. 4C, the water discharge pipe 42 is rotated to bring the magnet protrusion 48 into contact with the Hall IC 47a. Thus, the reset mode can be set.
In this example, after resetting the water discharge pipe 42 in this manner, the reset mechanism is activated by pressing and operating the contact switch 43 within a certain time, and resetting the open time counter and the use time counter. Can be executed.

  In this example, on the outer peripheral surface of the tubular casing portion 42b, a projection 48 'not provided with a magnet is provided at a position facing the magnet projection 48 across the axis P, and a groove portion engaged with the projection 48'. D ′ is also formed on the outer peripheral surface in the vicinity of the upper end of the inner casing 44 in a part in the circumferential direction (in this example, the central angle α is approximately 120 ° when the axis P is the center). That is, the water discharge pipe 42 of this example includes a protrusion 48 ′ formed on the outer peripheral surface of the tubular casing portion 42 b as a rotation limiting mechanism in which the rotation range of the water discharge pipe 42 is limited to a part in the circumferential direction. A groove portion D ′ formed on the outer peripheral surface near the upper end of the inner casing 44 and engaged with the protrusion 48 ′ is provided. However, in this example, the magnet projection 48 and the groove D that engages with the magnet projection 48 also act as a rotation limiting mechanism that limits the range of rotation of the water discharge pipe 42. Even if the groove D ′ that engages with the protrusion 48 ′ is not formed, the range of rotation of the water discharge pipe 42 is limited.

  A wiring member (not shown) that penetrates the inner casing 44 in the length direction is accommodated in the inner space 44a of the inner casing 44, and the base 47 and the control device 4 are electrically connected to the wiring member. Signal wiring to be connected, power wiring for electrically connecting the base 47 and a power supply (not shown), and the like.

The outer wall of the inner casing 44 is substantially cylindrical in the upper and lower portions of the inner casing 44, and has a substantially semicircular cross section in the vicinity of the protruding portion 42c of the tubular casing portion 42b as shown in FIG. In addition, between the outer surface of the inner casing 44 and the inner surface of the tubular casing portion 42b, a water storage portion 44b having a substantially semicircular cross section and communicating with the pipe portion 42a of the water discharge pipe 42 is provided. When the water storage part 44b is provided in this manner, water for discharging from the pipe part 42a of the water discharge pipe 42 is once stored in the water storage part 44b, and can be discharged from the pipe part 42a when a certain amount is reached. . As a result, the water discharge pressure can be adjusted appropriately.
A tubular joint 49 is liquid-tightly inserted into the inner casing 44 that forms the bottom surface 44c of the water reservoir 44b. The lower end of the joint 49 is connected to the water purification pipe 6, and the upper end is opened to the water storage part 44b. That is, the water storage part 44 b communicates with the water purification pipe 6 penetrating inside the faucet body 41 through the joint 49. Reference numeral 50 in the figure denotes an O-ring.

  The lower end of the inner casing 44 is screwed into the nut portion 52 of the annular member 51 fixed to the sink 30, and integrally covers the lower portion of the inner casing 44, the upper portion of the annular member 51, and the outer surface of the nut portion 52. Thus, a metal reinforcing member 53 is provided. A lower casing 45 b is provided outside the reinforcing member 53. The joint between the reinforcing member 53 and the lower casing 45 b is liquid-tightly sealed with an O-ring 54. Further, the lower end portion of the lower casing 45b, the lower end portion of the inner casing 44, and the lower end portion of the reinforcing member 53 are all fixed to the annular member 51 with bolts (not shown).

Next, in the water treatment apparatus of this example, a specific method for determining the replacement timing of the water purification means from the measured usage time, and then a specific mechanism for operating the reset mechanism when replacing the water purification means to reset the usage time A typical method will be described.
In the water treatment apparatus of the present embodiment, when the accumulated water discharge time from the purified water discharge port 11 (the integrated value of the opening time of the electromagnetic valve) exceeds the specified time, and the elapsed time from the start of use of the water purification means (use period) ) Exceeds the specified time, it is determined that the water purification means has reached the end of its life. In this embodiment, since the flow rate of the raw water supplied to the water purifier 7 is controlled to be constant by the constant flow valve 3, the water discharge accumulated time from the water purifier discharge port 11 is the amount of water processed by the water purifier 7 (process Is proportional to the integrated value (integrated flow rate).
In this example, when at least one of the case in which the accumulated water discharge time exceeds the specified time and the case in which the usage period exceeds the specified time occurs, the cartridge replacement sign 13 is notified. Yes.

In order to manage the accumulated water discharge time, for example, in the case of a one-year life-purifying means, the life at the integrated flow rate is defined as 12,000 liters, and the raw water flow rate determined by the constant flow valve 3 (the filtration flow rate in the water purification means and The same) is defined as 3.0 liters / minute. And the integration time which the solenoid valve provided in the control apparatus 4 was an open state is counted with an open time counter, and the time of 4000 hours is determined as the lifetime of the water purification means. That is, the threshold value of the integrated value of the open time is set to 4000 hours.
On the other hand, in order to manage the use period, the time when a new water purifying means is attached is defined as the start, and the use time counter starts counting. That is, the threshold for the usage period of the water purification means is set to one year.
Therefore, for example, even if the accumulated water discharge time has not reached 4000 hours, the cartridge replacement sign 13 is turned on when the usage period reaches one year.

Then, when the cartridge replacement sign 13 is lit in this way, the water purification means is replaced with a new one.
In this example, as shown in FIG. 4 (c), the water discharge pipe 42 is rotated to bring the magnet protrusion 48 and the Hall IC 47a into contact with each other to enter the reset mode. Press 43 to activate. As a result, the reset mechanism operates to reset the open time counter and the usage time counter.

In this example, after the water discharge pipe 42 is first rotated to be in the reset mode, the reset mechanism is activated by pressing and operating the contact switch 43 within a certain time. As long as the reset mechanism is operated by sensing the operation of the type switch 43 and the rotation of the water discharge pipe 42 performed simultaneously with the operation or within a certain time before and after the operation, the present invention is not limited to this mode.
For example, in the case of an electrical signal that opens and closes the solenoid valve by pressing the contact type switch 43 for a time longer than the pressing time for operating the operating means (for example, 3 seconds or more), that is, for a long time. Instead, it is set so that an electrical signal for setting the reset mode is sent to the control device 4. By doing so, first, the contact-type switch 43 is pressed for a predetermined time or longer to be in the reset mode, and then the water discharge pipe 42 is rotated within a certain time to bring the magnet protrusion 48 and the Hall IC 47a into contact with each other. The reset mechanism can be activated immediately. Alternatively, the reset mechanism can be operated by simultaneously rotating the water discharge pipe 42 while pressing and holding the contact switch 43 for a predetermined time or longer.

According to such a water treatment apparatus, when the water purification means is newly installed or replaced with a new one, in this example, an operation of pressing the contact switch 43 provided on the upper surface of the faucet body 41 or the like Then, the reset mechanism is operated by combining two different operations at different positions, that is, rotation of the water discharge pipe 42. Therefore, it is difficult for erroneous operations such as resetting to occur unexpectedly. Further, the operation of pressing the contact switch 43 provided on the upper surface of the faucet body 41 is an operation that can be easily performed by hand, and the operation of rotating the water discharge tube 42 is also performed on the tube portion 42a of the water discharge tube 42. Since it is an operation that only requires turning the part, it is excellent in operability.
Further, the contact switch 43 is originally provided in the faucet body 41 in order to control the opening and closing of the electromagnetic valve to switch between water discharge and water stop from the pipe portion 42a of the water discharge pipe 42, The water discharge pipe 42 is also a member that is originally necessary for constituting a water faucet. In this water treatment apparatus, since such a contact-type switch 43 and the water discharge pipe 42 are used for the operation of the reset mechanism, it is not necessary to newly provide a switch as a reset mechanism. Therefore, it is advantageous in terms of cost, and the design of the dedicated faucet 10 can be kept slim and simple, and the design is excellent.

  In this embodiment, the water discharge pipe 42 is provided with a rotation limiting mechanism, and the rotation range of the water discharge pipe 42 is limited to a part of the circumferential direction of the faucet body (in this example, the central angle α is approximately 120 °). In this case, the reset mode is set when the water discharge pipe 42 is rotated to one end of the rotation range. However, the present invention is not limited to this. For example, the range of rotation of the water discharge pipe 42 is set to the entire circumference (360 °) of the faucet body 41, and the reset mode is determined according to the positional relationship between the magnet projection 48 and the Hall IC 47a, or is determined as normal. It should be possible to distinguish whether it is done. However, when the range of rotation of the water discharge pipe 42 is limited to a part in the circumferential direction of the faucet body 41 and the water discharge pipe 42 is rotated to one end of the range of rotation as in the present embodiment. In addition, when the reset mode is set, the user can easily determine whether the user is in the reset mode or the normal mode, and for example, the pipe portion 42a of the water discharge pipe 42 wraps around toward the back as viewed from the user. It is possible to prevent water from being discharged to the top plate around the sink. In this example, the rotation range is set to 120 ° in consideration of ease of use and the like, but the present invention is not limited to this.

  Moreover, in this embodiment, since the contact-type switch 43 is provided in the upper surface part of the faucet main body 41, it is easy to operate by hand and operability is especially excellent. Further, since the upper surface portion of the faucet body 41 is relatively close to the installation position of the Hall IC 47a, only one base 47 is provided in the upper casing 45a, which is used for the contact type switch 43 and the Hall IC 47a. The faucet body 41 can be configured compactly. However, the portion where the contact switch 43 is provided is not particularly limited as long as it is the faucet body 41. Further, as a specific example of the operation means, the operation is simple as long as it is a contact type switch 43 that operates by pressing the switch, but the present invention is not limited to this, and other forms may be used. Examples of the contact type switch 43 include switches such as a push-down switch and a pressure-sensitive switch.

Furthermore, although the threshold value of the integrated value of the open time is 4000 hours and the threshold value of the use period of the water purification means is one year in the above description, the water purification means is exemplified, but depending on the type of the water purification means These thresholds are different. Therefore, when the water purification means is replaced with a different type, it is necessary to change the threshold setting. Therefore, it is preferable that the management unit of the water treatment apparatus includes a threshold setting mechanism that sets the threshold according to the type of the water purification unit.
In that case, the threshold setting mechanism is activated by pressing the contact-type switch 43 and detecting rotation of the water discharge pipe 42 performed simultaneously with such operation or within a certain period of time. It may be. Thereby, as in the case of the reset mechanism, the threshold setting mechanism can be operated with good operability without erroneous operation, which is preferable in terms of cost and design of the water treatment apparatus.

  Specifically, when operating the threshold setting mechanism, a method of presetting the long pressing time of the contact type switch 43 to be different from that at the time of operating the reset mechanism, or rotating the water discharge pipe 42 For example, a method may be used in which the contact time when the magnet projection 48 and the Hall IC 47a are brought into contact with each other is set in advance to be different from that when the reset mechanism is operated. Thereby, the operation of the reset mechanism and the operation of the threshold setting mechanism can be discriminated. Further, if the time for pressing the contact switch 43 and the contact time are individually set in advance so as to correspond to the type of water purification means, the long press time and the contact time can be changed. The threshold value can be set according to the type of the water purification means.

  Further, for example, as shown in FIG. 6, there is a method in which Hall ICs 47 a and 47 a ′ are respectively installed at both ends of the groove portion D formed on the outer peripheral surface of the inner casing 44. When two Hall ICs 47a and 47a ′ are installed in this way, for example, when the magnet projection 48 comes into contact with one Hall IC 47a, the reset mechanism is activated, and when the magnet projection 48 comes into contact with the other Hall IC 47a ′. It is also possible to configure the water treatment device by operating the threshold setting mechanism.

Furthermore, the water treatment apparatus may include an automatic water discharge means that automatically and periodically discharges the staying water staying in the water treatment means. By providing automatic water discharge means, for example, when the water treatment device has not been used for a certain period of time, it is possible to automatically discharge stagnant water at a predetermined flow rate for a predetermined time, so that water suitable for drinking is obtained. It can also be obtained at any time.
In that case, it is preferable to provide an on / off setting mechanism for turning on and off the operating state of the automatic water discharging means. For example, when the user is absent for a long period of time due to travel or the like, it is preferable that the automatic water discharge means not be used unnecessarily. Therefore, it is preferable that the operation state of the automatic water discharge means can be appropriately turned on and off for the convenience of the user. is there.
Further, the on / off setting mechanism is operated by pressing the contact type switch 43 and detecting the rotation of the water discharge pipe 42 performed simultaneously with such an operation or within a certain period of time. Also good. Thereby, as in the case of the reset mechanism, the on / off setting mechanism can be operated with good operability without erroneous operation, which is preferable in terms of cost and design of the water treatment apparatus. Specifically, even when the on / off setting mechanism is operated in this way, the time for which the contact type switch 43 is long pressed is set in advance so that it is different from the time when the reset mechanism is operated and the time when the threshold setting mechanism is operated. And a method in which the contact time between the magnet protrusion 48 and the Hall IC 47a is set in advance so as to be different from the time when the reset mechanism is operated and the time when the threshold setting mechanism is operated. Thereby, the operation of the reset mechanism, the operation of the threshold setting mechanism, and the operation of the on / off setting mechanism can be discriminated. In addition, as shown in FIG. 6, a method of installing a plurality of Hall ICs 47a and 47a ′ may be used.

In addition, in this embodiment, although the water purification means was illustrated as a water treatment means, not only this but another water treatment means may be sufficient. For example, instead of the water purifier 7, an alkali ion water conditioner may be used. In this case, the dedicated water faucet 10 may be provided with a water discharge outlet branched into two so that alkaline water and acidic water generated by electrolysis in the electrolytic cell can be discharged separately.
Moreover, in this embodiment, although demonstrated using the solenoid valve as an example of an on-off valve, it replaced with a mere on-off valve, 3 of the water discharge of the purified water obtained by the water purification means, the water discharge of raw | natural water, water stop, etc. You may use the flow-path switching valve which combined two functions, a plug valve, etc. When a plug valve is used, the plug valve and the contact switch 43 may be connected by a wire instead of electrical wiring.

  Moreover, in this embodiment, as use time for determining the replacement | exchange time of a water treatment means, the integrated value of the opening time of a solenoid valve (integrated value of the discharge time of purified water) and the use period of a water purification means (new water purification means) Elapsed time since the start of use of the water), so the life of the water purification means can be determined more properly, but depending on the case, either the integrated value of the solenoid valve opening time, the duration of use of the water purification means Only one of them may be adopted, or another parameter may be adopted as an index of the period of use.
