Abstract

PROBLEM TO BE SOLVED: To provide a cleaning device for collected water in which both maintenance of activity of aerobic bacteria in a cleaning part and control of increase in anaerobic bacteria in the case for unnecessitating cleaning of collected water are enabled by less suppressing power consumption. SOLUTION: When use and nonuse of the cleaning device are distinguished (S3) and it is distinguished that the cleaning device is not used, a pump for circulating collected water through a cleaning part is intermittently actuated (S10). Thereby, replacement of collected water remaining in the cleaning part and collected water except the cleaning part is performed sometimes. Oxygen dissolved in collected water except the cleaning part is sufficiently supplemented to the cleaning part. In this case, such a method is adopted that an air pump directly sending air to the cleaning part is intermittently actuated instead of intermittent actuation of the pump.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for purifying stored water for circulating and purifying stored water such as bath water.

[0002]

2. Description of the Related Art In recent years, for example, bath water stored in a bath tub is discarded every time bathing is performed.
Bath water purifiers are provided that can be used without replacing the bath water for months. This bath water purifier circulates the bath water in the bathtub with a pump, removes coarse garbage from the circulated bath water with a filter, and removes fine garbage, dirt, smell, etc. (organic matter) mainly in the purifying section. It is designed to purify by decomposing and removing the biofilm generated on the surface of the quality purification material. In this case, the decomposition and purification of organic matter by the biofilm of the purification section are performed mainly by aerobic bacteria and air-permeable bacteria in various ways.

[0003]

In the above bath water purifying apparatus, it is said that it is necessary to keep the apparatus running even when the user does not need to take a bath for a while and need to purify the bath water. Was. This is because the aerobic bacteria that decompose and purify the above-mentioned organic substances need oxygen to maintain the activity, and if the oxygen is insufficient, the number of aerobic bacteria decreases, and the purification of bath water is not performed well. . When oxygen is insufficient, an anaerobic bacterium increases, so-called odor peculiar to odor is emitted, and the bathroom becomes odorous. Further, once the odor becomes odor, the odor cannot be easily removed even if the bath water purification device is operated again.

[0004] For these reasons, it has been said that it is necessary to keep the bath water purifying device running even when it is not necessary to purify the bath water. The bath water in the bathtub is replaced, and oxygen that is dissolved in the bath water in the bathtub is supplemented to the purification unit. However, for that reason, the conventional apparatus that keeps operating the bath water purification device has a problem that the power consumption increases and the electricity cost increases.

[0005] The present invention has been made in view of the above circumstances, and it is therefore an object of the present invention to maintain the activity of the aerobic bacteria in the purification section and to maintain the anaerobic bacteria in the case where it is not necessary to purify the pool water such as bath water. An object of the present invention is to provide a storage water purifying apparatus capable of suppressing an increase in power consumption while reducing power consumption.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, a storage water purifying apparatus according to the present invention comprises, first, a pump for circulating stored water and removing coarse dust from the circulated stored water. And a purifying unit for purifying by removing fine dirt, dirt, odor, etc. from the circulating pool water, and comprising a discriminating means for discriminating use or non-use of the device. An intermittent operation of intermittently operating the pump when it is determined that the device is not used is performed.

When it is not necessary to purify stored water such as bath water (when the apparatus is not used), as described above, in order to maintain the activity of aerobic bacteria in the purifying section and to suppress the increase of anaerobic bacteria. In addition, it is necessary to supplement the purification section with oxygen. For this purpose, it is sufficient to replace the pool water such as bath water remaining in the purification section with the pool water outside the purification section such as bath water in the bathtub. Oxygen dissolved in the pool water outside the purification section can be sufficiently supplemented.

Therefore, as described above, in the system in which the pump for circulating the accumulated water is intermittently operated when the apparatus is not used, the accumulated water remaining in the purification section and the accumulated water outside the purification section are not changed. Oxygen dissolved in the water outside the purification unit is sufficiently supplemented to the purification unit, and the pump is operated intermittently instead of continuously to reduce power consumption. It can be kept low.

Secondly, the stored water purifying apparatus of the present invention comprises a pump for circulating the stored water, a filter for removing coarse dirt from the circulated stored water, and a fine dirt and dirt from the circulated stored water. And a purifying section for purifying by removing odors and the like, comprising an air pump for sending air to the purifying section, and a discriminating means for discriminating use / non-use of the device. Is characterized by performing an intermittent operation of intermittently operating the air pump when it is determined that the air pump is not used.

When it is not necessary to purify the stored water (when the apparatus is not used), oxygen is supplemented to the purifying section in order to maintain the activity of the aerobic bacteria in the purifying section and to suppress the increase of anaerobic bacteria. It can also be done by sending air directly into the purification section. Further, oxygen can be sufficiently supplemented to the purifying section by sending air to the purifying section only occasionally.

Therefore, as described above, in the intermittent operation of intermittently operating the air pump for supplying air to the purifying section when the apparatus is not used, the air is supplied to the purifying section occasionally. Oxygen is sufficiently supplemented to the purifying section, and power consumption can be reduced by operating the air pump not intermittently but intermittently.

The control device 36 is composed of a microcomputer, and determines whether the bath water purification device is used or not as described later. And a control means for controlling the operation of the bath water purification device. The plug 37 is inserted and connected to a power outlet (not shown). 39 and a stabilized DC power supply circuit 40 in order to supply necessary DC power.

Further, relay contacts 41 and 4 opened and closed by the control device 36 are connected to both terminals on the secondary side of the insulating transformer 39.
Power lines 43 and 44 are connected to the pump motor 6 through the pump motor 6 respectively.
And electric heater 16, ultraviolet lamp 14, and solenoid valve 2
1, a relay contact 45 opened and closed by the control device 36,
46, 47, and 48 are connected to each other.

Further, the controller 36 receives various switch signals from a switch input unit 49 comprising various switches 22 to 27 of the operation panel 22 and also circulates bath water 10 in the bathtub 9 as described later. A water temperature detection signal is input from a water temperature sensor 50 provided so as to detect the temperature at a predetermined position in the circulation path, and based on those inputs and a control program stored in advance. The control device 36 opens and closes the above-mentioned relay contacts 41, 42, 45-48, and controls the display on the display unit 51 of the operation panel 22 including the various indicators 29-32, 34, 35 and the display 33. It gives a signal.

Next, the operation of the above configuration will be described. First, prior to use of the bath water purification device, the bath water purification device is set on a peripheral portion of the bathtub 9. In this state, the bathtub 9
In the bath water 10 inside, the inlet part of the suction pipe 7 (the filter 8 part) and the outlet part of the discharge pipe 17 (the nozzle 18 and the ejector 2).
0), and the plug 37 is plugged into a power outlet (not shown).
Operate the power switch (not shown) provided in. Then, necessary DC power is supplied to the control device 36 via the leakage protection device 38, the insulation transformer 39, and the DC stabilizing power supply circuit 40 in that order, and the control device 36 performs initialization shown in FIG. 1 (step S1). Then, it is determined whether or not the "drive" switch 23 has been operated (step S2).

In step S2, the "run" switch 2
If it is determined that No. 3 has not been operated (NO), control device 36 waits by repeating step S2, but if it is determined that it has been operated (YES), it closes relay contacts 41 and 42. Further, it is determined whether the "outing" switch 24 has been operated (step S3).

The "outing" switch 24 is used by the control device 36 to determine whether the bath water purifier is used or not. In step S3, the "outing" switch 24 is used.
If it is determined that is not operated (NO), it is determined that the bath water purification device is used, and if it is determined that the “outing” switch 24 is operated (YES), the bath water purification device is used. Is determined (not used).

If it is determined that the bath water purifier is to be used (the "outing" switch 24 is not operated), the control device 36 closes the relay contact 45 to open the pump motor 6. , The pump 2 is operated (step S4). By the operation of the pump 2, bath water 10 is sucked from the bathtub 9 into the pump 2 through the filter 8 and the suction pipe 7. At this time, the filter 8 removes coarse dust such as hair, lint, and skin fragments contained in the bath water 10.

The bath water 10 sucked into the pump 2 is then sent to the purification section 3 through the connecting pipe 11, subsequently sent to the sterilizing section 4 through the connecting pipe 13, and further connected to the connecting pipe 15. Is returned to the bathtub 9 from the nozzle 18 through the discharge pipe 17, and is then circulated repeatedly through the filter 8 and the suction pipe 7 into the pump 2.

In this circulating path, the purifying section 3 purifies the purifying material 12
Microorganisms such as aerobic bacteria and air-permeable bacteria contained in the bath water 10 are adsorbed on the surface of the bath water, and the microorganisms are overlapped to form a biofilm in a layered manner. The biofilm removes the aforementioned coarse dust. Fine dust, dirt, smell and the like (organic substances) contained in the bath water 10 after being decomposed are decomposed and removed and purified. The decomposition and purification of organic substances by the biofilm of the purification section 3 are performed mainly by aerobic bacteria and air-permeable bacteria in various ways.

After step S4, the control device 36 determines whether the "heat keeping" switch 25 has been operated (step S5). Here, the "heat retention" switch 25
Is operated (YES), the water temperature sensor 5
It is determined whether or not the bath temperature detected by 0 is higher than the hot water temperature set by the "hot water temperature setting" switches 26 and 27 (step S6). If the determination is NO, the relay contact 46 is closed and the electric heater 16 is energized to generate heat (step S7). As a result, the bath water 10 is heated by the electric heater 16 in the course of passing through the heating unit 5 and its temperature is raised.

If it is determined in step S6 that the bath water temperature is equal to or higher than the set hot water temperature (YES), the relay contact 46 is opened to turn off the electric heater 16 in the opposite manner as described above. As a result, the heat generation of the electric heater 16 is stopped (step S8). Thereby, bath water 10 is heated
The heating by the electric heater 16 in the process of passing is stopped and the temperature is lowered. If it is determined in step S5 that the "warming" switch 25 has not been operated (NO), the process proceeds from step S6 to step S8.

Further, after step S7 or step S8, the controller 36 turns on the ultraviolet lamp 14 by closing the relay contact 47 and energizing the ultraviolet lamp 14 for a predetermined time (step S9). ). Thus, the bath water 10 is sterilized by being exposed to ultraviolet rays emitted from the ultraviolet lamp 14 in the process of passing through the sterilizing section 4 before passing through the heating section 5 described above.

On the other hand, if it is determined in step S3 that the "outing" switch 24 has been operated (YES) (it is determined that the bath water purification device is not used), the control device 36 determines whether the When the time at which the "outing" switch 24 is operated is reached, the pump 2 is operated by closing the relay contact 45 and energizing the pump motor 6 for a predetermined time, for example, 10 minutes (step S10). Also, while the pump 2 is operating, the relay contact 48 is closed at the same time to energize the solenoid valve 21 to open the solenoid valve 21. Furthermore, this pump 2
Is operated and the electromagnetic valve 21 is opened, the relay contact 47 is closed at the same time, and the ultraviolet lamp 14 is energized, so that the ultraviolet lamp 14 is turned on.

As a result, the circulation of the bath water 10 is reduced by one.
It is performed only for 10 minutes during the day, and at the same time, the air outside the main body 1 is sucked through the air hose 19 and the solenoid valve 21 by the pressure difference between the ejector 20 and the bath water 10 passing therethrough,
Therefore, the bath water 10 passing through the ejector 20 is returned from the nozzle 18 into the bath water 10 in the bathtub 9, and the air sucked from outside the main body 1 is jetted into the bath water 10 in the bathtub 9. Is entered. At this time, sterilization by bathing in ultraviolet rays emitted from the ultraviolet lamp 14 while the bath water 10 passes through the sterilizing section 4 is also performed. After step S10 or the previous step S9, control device 36 returns to step 2 and repeats the above operation.

As described above, in the case of this configuration, when the user does not need to take a bath for a while to go out and does not need to purify the bath water (when the bath water purifier is not used), the "outing" switch 24 is operated. Based on this, the control device 36 determines that the bath water purification device is not used, and
By operating the pump 2 only for 0 minutes, an intermittent operation is performed in which the pump 2 is intermittently operated every 10 minutes at intervals of 23 hours and 50 minutes. As a result, the bath water 10 remaining in the purification unit 3 and the bath water 10 outside the purification unit 3 (in the bathtub 9) are occasionally replaced (for example, only for 10 minutes in one day).
It is something that is performed, and even at this occasional replacement,
The oxygen dissolved in the bath water 10 outside the purification unit 3 (in the bathtub 9) is sufficiently supplemented to the purification unit 3.

Therefore, the activity of the aerobic bacteria in the biofilm of the purification section 3 can be sufficiently maintained, the decrease of the aerobic bacteria can be prevented, and the increase of the anaerobic bacteria can be suppressed. Therefore, it is possible to satisfactorily purify the bath water 10 when the purifying operation is performed again, and it is also possible to suppress the generation of a peculiar smell due to the anaerobic bacteria. In addition, the pump 2 is not operated continuously, but is operated intermittently, so that power consumption can be reduced.
Electricity bill can be saved.

In this case, the power consumption of the pump 2 is reduced to 120
[W], in the case of the conventional pump in which the pump 2 is continuously operated, the power consumption of the pump 2 per day (24 hours) is 120 [W] × 24 hours = 2880 [Wh]. Assuming that the cost is 1 [kW] and 23 yen, the daily electricity cost is 2880 [Wh] × 23 yen / 1000 [W] = about 66 yen.

On the other hand, in the case of this configuration in which the pump 2 is operated intermittently as described above, even if the power consumption of the pump 2 is the same at 120 [W], the operation is performed 10 times a day.
Since it is performed for only a minute (about 0.167 hours), the power consumption of the pump 2 per day is 120 [W] × 0.167 hours = 20 [Wh], and the electricity bill is 1 [kW]. Assuming 23 yen
The daily electricity bill is 20 [Wh] × 23 yen / 1000 [W] = 0.46 yen, and a sufficient electricity bill can be saved.

The operating time of the pump 2 per day is set to 10 minutes for the following reasons. That is, the amount of bath water 10 that normally enters the bathtub 9 is 200 [l],
The circulation capacity of the bath water 10 by the pump 2 is set to 20 [l / min].
Then, 200 [l] ÷ 20 [l / min] = 10 minutes, and the bath water 10 in the bathtub 9 can be circulated once in 10 minutes.

In the case of this configuration, the bath water 10 in the bathtub 9 has a function of simultaneously injecting air when the bath water is circulated and returned (the ejector 20). At the same time as the operation of the pump 2. Thereby, the bath water 10 in the bathtub 9 can be supplemented with oxygen, and the amount of dissolved oxygen in the bath water 10 can be increased, so that the oxygen dissolved in the bath water 10 can be supplied to the purification unit 3 more. Can be performed sufficiently.

Therefore, the activity of the aerobic bacteria in the biofilm of the purification section 3 can be maintained, the decrease of the aerobic bacteria can be prevented, and the increase of the anaerobic bacteria can be suppressed more effectively. The purification of the bath water 10 when the purification operation is performed can be performed more favorably, and the generation of a peculiar smell due to the anaerobic bacteria can be suppressed more reliably.

5 to 7 show a second embodiment of the present invention. Only parts different from the first embodiment will be described. In this case, first, as shown in FIG. 5, the solenoid valve 21 is not provided in the air hose 19, and the air outside the main body 1 sucked by the ejector 20 from the air hose 19 at the time of the purifying operation is always supplied from the nozzle 18 to the bath water 10.
At the same time, the water is injected into the bath water 10 in the bathtub 9, whereby jet bubbles are generated in the bath water 10 in the bathtub 9, and a massage effect can be obtained.

In this case, an air pump 61 for sucking in air from outside the main body 1 and sending it is connected to a connecting pipe 11 connecting the pump 2 and the purifying section 3 via a check valve 62. The check valve 62 functions to prevent the circulated bath water 10 from leaking out of the main body 1 from the connection pipe 11 through the air pump 61. Further, in the electric circuit configuration, as shown in FIG. 6, the pump motor 63 of the air pump 61 is connected via a relay contact 64 opened and closed by the control device 36 instead of the electromagnetic valve 21.

In operation, as shown in FIG.
In step S3, when it is determined that the "outing" switch 24 has been operated (YES) (determined that the bath water purification device is not used), the control device 36 replaces the above-described step S10 and executes the day. When the time at which the "outing" switch 24 is operated is reached, the air pump 61 is operated by closing the relay contact 64 and energizing the pump motor 63 for a predetermined time, for example, the same 10 minutes as above. (Step S101).

Thus, when there is no need to purify the bath water 10 (when the bath water purifier is not used), the air pump 61
Is operated intermittently for every 10 hours at intervals of 23 hours and 50 minutes. The activated air pump 61 sucks air from outside the main body 1 and enters the connection pipe 11 through the check valve 62. And then into the purifier 3 through the connecting pipe 11. Therefore, in this case, instead of the above-described circulation operation of the bath water 10, the direct supply of air to the purification unit 3 is performed occasionally, and the direct supply of air to the purification unit 3 performed occasionally is performed. However, the purifying section 3 is sufficiently supplemented with oxygen.

Thus, as described above, the activity of the aerobic bacteria in the biofilm of the purification section 3 can be sufficiently maintained.
A decrease in aerobic bacteria can be prevented, and an increase in anaerobic bacteria can be suppressed. Therefore, it is possible to satisfactorily purify the bath water 10 when the purifying operation is performed again, and it is also possible to suppress the generation of a peculiar smell due to the anaerobic bacteria.

Further, the air pump 61 is not operated continuously but intermittently, so that the power consumption can be reduced and the electricity cost can be reduced.

In this case, the power consumption of the air pump 61 is reduced by 5
[W], the power consumption of the air pump 61 per day in the second embodiment in which the air pump 61 is operated for 10 minutes (about 0.167 hours) per day is 5 [W] × 0. .167 hours = 0.835 [Wh], and if the electricity bill is 1 [kW] and the same as the above-mentioned 23 yen, the electricity bill per day is 0.835 [Wh] x 23 yen / 1000 [W] = About 0.
It is 02 yen, and you can save enough electricity bill.

FIGS. 8 and 9 show a third embodiment of the present invention, in which only parts different from the first embodiment will be described. In this case, as shown in FIG. 8, the "outing" switch 24 is operated in step S3 (YE).
S) (determined that the bath water purification device is not used), the control device 36 replaces the aforementioned step S10 with a predetermined time, for example, 8 hours from the time when the "outing" switch 24 is operated. The pump 2 is operated continuously, and thereafter, the intermittent operation of the pump 2 accompanied by the opening of the electromagnetic valve 21 and the lighting of the ultraviolet lamp 14 is performed (step S201).

FIG. 9 shows the change in the degree of contamination of the bath water 10 based on the experimental results of the inventor. After bathing from the first person to the fourth person, the pump 2 is continuously operated as described above to purify the water. When the operation was performed, the purification rate was 90 in the fifth hour.
[%], And reached 95 [%] by 8 hours.

Accordingly, as described above, the pump 2 is continuously operated for 8 hours from the time when the "outing" switch 24 is operated, and thereafter, the above-mentioned electromagnetic valve 21 is opened and the ultraviolet lamp 14 is turned on. In the case of performing the intermittent operation of the pump 2, the operation of supplementing oxygen dissolved in the bath water 10 is performed in the purification unit 3 after the purification rate of the bath water 10 is increased to 95 [%]. Unlike the case where the oxygen supply operation is performed while the device 10 is dirty, the bath water 10 can be efficiently purified when the purification operation is performed again. In addition, the purification rate of the bath water 10 is obtained by the following equation. Purification rate = (dirty level before purification-dirt level after purification) / dirt level before purification

FIG. 10 shows a fourth embodiment of the present invention, and only parts different from the first embodiment will be described. In this case, when it is determined in step S3 that the "outing" switch 24 has been operated (YES) (determined that the bath water purification device is not used), the control device 3
6 is "outing" instead of step S10 described above.
The pump 2 is continuously operated for a predetermined time, for example, 8 hours from the time when the switch 24 is operated, and thereafter, the above-described intermittent operation of the air pump 2 is performed (step S301).

In this way, after the purification rate of the bath water 10 reaches 95 [%], the main body 1
Although it changes so that the operation of supplementing oxygen is performed by directly sending outside air, the bath water 10 is supplied as described above.
Unlike the case where the oxygen supply operation is performed while the water is dirty, the bath water 10 can be efficiently purified when the purification operation is performed again.

The continuous operation of the pump 2 before the oxygen replenishment operation may be performed for 5 hours when the purification rate reaches 90 [%], or may be performed for less than 8 hours or more. You may do it. In addition, the intermittent operation of the pump 2 is not limited to 10 minutes per day, but
Or you may make it take more time. However, even if it takes more than 10 minutes a day, it is desirable to keep the total time less than one hour per day from the viewpoint of saving electricity bills.

Further, the intermittent operation of the air pump 61 is not limited to 10 minutes a day, but may be performed for a shorter time or longer. Replenishment is efficiently performed by air instead of the dissolved state of the bath water 10, and may be performed, for example, about once every two days. In addition, in each of the above embodiments, the present invention has been described as applied to a bath water purification device. However, the present invention can be similarly applied to a device for purifying pooled water other than bath water, for example, water in a pool. it can.

In addition, as the purifying material 12 of the purifying section 3, in addition to the above-mentioned various porous natural ores and ceramics, even a fiber filter capable of decomposing and purifying organic substances by the same biofilm can be used. Further, physical purification such as a coagulation method in which a dirt component having a negative potential is solidified and removed using the positive potential of aluminum hydroxide may be used.

The sterilizing section 4 may incorporate a photocatalyst together with the ultraviolet lamp 14, and the "outing" switch 2 may be used as a discriminating element between use and non-use of the purifying device.
In addition, for example, in the case of bath water 10, if the user takes a bath, the temperature of the hot water drops. Therefore, the bath temperature is detected by the fluctuation of the hot water temperature, and when the bathing is not detected for a predetermined time, purification is performed. The apparatus may determine that the apparatus is not used and perform the control as described above.
