Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a method for suppressing the growth of various bacteria around a water discharge device.
[0002]
[Prior art]
Conventionally, a watering device equipped with a water discharge device such as a normal water discharge faucet or a dedicated water discharge nozzle according to the purpose, for example, a kitchen sink, a vanity, a water heater, a water conditioner, a water purifier, and an automatic handwasher There is also a combination of these.
[0003]
The water discharger provided in these water-related devices is connected to a terminal of a water supply pipe that is connected to a water source, and water is discharged and stopped by opening and closing an on-off valve.
[0004]
On the other hand, in recent years, awareness of health has improved socially, and for drinking water in ordinary households, instead of drinking directly from tap water, a water purifier or a water conditioner is installed to supply purified water. The number of households used is increasing.
[0005]
[Problems to be solved by the invention]
However, since the water-equipment provided with the above-mentioned water discharger uses a water discharger with an open / close stopper, it is unavoidable that residual water is generated in the water discharger and in the pipe communicating therewith after the plug is closed. Absent.
[0006]
In particular, if alkaline water or dechlorinated purified water, which is considered to be good for health, stays for a long time without being used, germs are more likely to grow than general tap water.
[0007]
Therefore, when these water treatment devices are installed, there is no problem with the amount used in daily life, but when using for a long period of time, such as when you are away for a few days, for example, when traveling, In surrounding devices, it is preferable to use the water after drinking water from the water discharger for a predetermined time (predetermined amount) and disposing of the accumulated water.
[0008]
However, it is troublesome to dispose of such water, and since there is little awareness of disposing of water, even if it has not been used for a long time, it often drinks water immediately after opening the cap .
[0009]
In this case, the water-surrounding equipment introduced for health becomes adversely affected, and there is a risk that health may be adversely affected by ingesting various germs.
[0010]
An object of the present invention is to provide a method for suppressing the growth of germs around a water discharger that can solve the above-mentioned problems.
[0011]
[Means for Solving the Problems]
  In order to solve the above-mentioned problem, in the present invention according to claim 1, a water-surrounding device provided with a water dischargerofIn the method for suppressing the growth of germs around the water spouting device, the water staying in the water spouting device and in the flow passage communicating with the water spouting device are automatically discharged regularly to suppress the growth of germs.The automatic water discharge is set to run once a day, and the number of hours after the set automatic water discharge is allowed to be counted down with a numerical value of 1 to 24, and that automatic water discharge is being executed. Displayed with numerical value 0.
[0012]
  Further, in the present invention described in claim 2,When the normal water discharge operation is performed by a predetermined time before the time set as the automatic water discharge execution timing, the automatic water discharge is canceled.
[0017]
DETAILED DESCRIPTION OF THE INVENTION
The present invention, in a water-equipment equipped with a water discharger, is designed to suppress the growth of germs by automatically discharging the retained water in the water discharger and the flow passage communicating with the water discharger periodically. is there.
[0018]
That is, if water is retained more than this, water is regularly discharged for a predetermined time at an interval shorter than the time at which miscellaneous bacteria may propagate, so that the water remaining in the water discharge device is discarded and new water is introduced. Then, the next time the user takes water from the water discharger, control is performed so that no germs are included.
[0019]
Therefore, even if you are using water-related devices such as water purifiers or water conditioners, and you are away for several days on a trip, etc., it is possible to automatically drain the accumulated water while you are away and ensure that germs grow. Since it can be prevented, it is not necessary to bother to throw away water after returning home, and the water-related equipment introduced for health can be used with peace of mind.
[0020]
In the present embodiment, the water discharge for performing the waste water is automatically executed once a day, that is, once every 24 hours, so that the user is not required any trouble.
[0021]
In order to perform such automatic water discharge, the water discharger can discharge and stop water by opening and closing an electromagnetic valve that is driven by electrical control, and can automatically discharge water easily by electrical control.
[0022]
As a method of first setting the execution timing of automatic water discharge, it can be set to a time after a certain period of time has elapsed since the timing setting operation performed first after installing the water-circulating device.
[0023]
For example, a setting unit that sets the execution timing of automatic water discharge is provided in a water supply device equipped with a water discharger, and when the user purchases and installs the water supply device and turns on the power, this setting operation is performed by the setting unit. It is possible to appropriately set how many hours after the automatic water discharge.
[0024]
Therefore, it is not necessary to set the current time and set the time for automatic water discharge again, and the automatic water discharge time can be set very easily.
[0025]
Moreover, when the execution timing of the automatic water discharge has been set, a display unit that counts down the number of the automatic water discharge that has been set from this time to the time after the set time with a number from 1 to 24 Is preferably provided. As a countdown display form, a 7-segment LED display can be used, but a liquid crystal display may also be used.
[0026]
In this embodiment, after the setting, when the time of execution timing comes, the solenoid valve is opened for a predetermined time to discharge water, and the display unit displays that automatic water discharge is being performed with the numeral “0”. I am doing so.
[0027]
The running time of automatic water discharge should be set to a time that is sufficient to drain all the water staying in the pipe and the water discharge device, such as normal water pressure, the volume in the water discharge device, and the pipe volume. It may be calculated from the above and determined in advance at the time of shipment from the factory.
[0028]
That is, when a device around the water is purchased and installed, the power is turned on, and the time for setting the automatic water discharge timing by the setting unit is 3:00 pm, automatic water discharge is performed at 2:00 am in the evening. In order to do so, the user may input the set time as 11 (how many hours later the automatic water discharge is performed).
[0029]
Then, the number “11” is displayed on the display unit, and countdown display in which the number decreases every hour is started.
[0030]
Therefore, at midnight when 9 hours have passed, “2” is displayed on the display unit, and it can be seen that automatic water discharge starts after 2 hours.
[0031]
When 1 hour elapses, the display changes to “1”, and at the moment when it changes from 1 am to 2 am, the number on the display changes from “1” to “0” and the time is up, and automatic water discharge starts at 2 am For 1 minute.
[0032]
In the present embodiment, in order to display that automatic water discharge is being executed, such “0” display is continued for one minute.
[0033]
That is, the number “0” itself indicating the time used in the display unit for countdown display is used as a sign indicating that the target operation is being performed, and a display unit for displaying that automatic water discharge is being performed is separately provided. Eliminates the need to install.
[0034]
When the automatic water discharge for 1 minute is completed, a numerical value “24” indicating that the time until the automatic water discharge at 2 am on the next day, that is, 24 hours later, is displayed on the display unit. That is, the display of “24” actually continues for 59 minutes. After that, the display changes in order of “23”, “22”,..., “2”, “1” every 1 hour (60 minutes).
[0035]
In a display unit such as a conventional timer device, when the set target execution time is displayed in a countdown manner at an interval of 24 hours, since 24 hours later is the same as the current time, there is no concept of displaying the number “24”. It is common to use numbers “0” to “23” as time indications.
[0036]
In other words, “1” is displayed after one hour, and even if it is the same until it changes to “0” at the moment when the time is up, this “0” display continues for one hour, and then the number “23” is displayed. Will be.
[0037]
Therefore, the execution purpose may be a momentary operation such as turning on / off the power supply, or it may be executed continuously for 60 minutes of 1 hour, but as described above, for example, 1 minute. If it is to be executed for a limited time of 60 minutes or less like this, to indicate that the target is being executed, the lamp is turned on separately. Need to be displayed.
[0038]
In this embodiment, a limited short time during the target execution is displayed as “0”, and even if the time is less than one hour obtained by subtracting the execution time from 60 minutes, the number “24” is displayed. Therefore, the display immediately after the purpose execution is “24”, and it can be intuitively recognized that the purpose is executed again after 24 hours.
[0039]
Moreover, as another method, the execution timing of automatic water discharge can be set by calculating the use off time from the use history of the water-related devices.
[0040]
This is done by installing a microcomputer in the water-circulating device and calculating the number of times water is discharged from the water discharger, the interval between water discharge and water discharge, the frequency of water discharge per fixed time, etc. in conjunction with the timer function. The time zone with the fewest opportunities for water discharge is calculated in the day, and the time for automatic water discharge is determined appropriately within this time zone. Then, as described above, automatic water discharge is performed at intervals of 24 hours.
[0041]
With this configuration, the user can cause automatic water discharge once a day at an optimal timing without determining the time for automatic water discharge by himself / herself.
[0042]
Moreover, the execution timing determination of automatic water discharge can be updated for every week from the latest usage history information calculated for example per week. By doing in this way, it can always be set as the automatic water discharge timing according to a user's new lifestyle.
[0043]
In addition, if the interval of automatic water discharge is a multiple of 24 hours, automatic water discharge can also be performed at the set time for several days. If it is set as the interval of 48 hours, automatic water discharge will be performed at a predetermined time once every two days.
[0044]
In addition, when a normal water discharge operation is performed before a predetermined time (set as a cancellation time zone) before the time set as the automatic water discharge execution timing, it is desirable to cancel the automatic water discharge from the viewpoint of saving water.
[0045]
In other words, it is usually sufficient to perform automatic water discharge to prevent the growth of various bacteria once a day or every two days, but it has a significant effect on the growth of bacteria, such as when the cancellation time zone is set to 2 to 3 hours, for example. If the normal water discharge operation is performed before the automatic water discharge set time within the time when no water is given, the automatic water discharge set just 2-3 hours after the normal water discharge is canceled.
[0046]
With this setting, automatic water discharge is not performed if normal water discharge is performed within the cancellation time zone, but the stagnant water is always flowed by the normal water discharge operation, so that the purpose of preventing germ growth can be achieved.
[0047]
Further, in a time zone other than the cancellation time zone, even if there is normal water discharge, automatic water discharge is performed at the set time, so automatic water discharge is surely performed once a day.
[0048]
On the other hand, if the cancellation time zone is set to a long time such as 12 hours or 24 hours, automatic water discharge is rarely performed as long as it is used normally except when traveling away for a long time.
[0049]
【Example】
Embodiments of the present invention will be specifically described below with reference to the drawings.
[0050]
FIG. 1 is an explanatory view showing an installation state of an undersink type water conditioner as a water-equipment equipped with a water discharger according to the present embodiment, FIG. 2 is an explanatory view of the water adjuster, and FIGS. The flowchart which shows the Example of the germ growth suppression method around the water discharging tool which concerns on invention, FIG.5 and FIG.6 is explanatory drawing which shows the Example in time series.
[0051]
In FIG. 1, reference numeral 1 denotes a sink. A sink 10 is formed on a part of the sink top plate 1a, and a storage portion 11 is formed inside.
[0052]
The sink 10 is connected to the water supply pipe 2 through a water heater (not shown), and is provided with a water discharge device 3 formed in an inverted J shape. The water discharge port 31 formed at the tip of the water discharge device 3 is connected to the sink 10. 10
[0053]
Further, the water discharger 3 is provided with a valve box 4 in which an electromagnetic on-off valve and a flow path switching valve (not shown) are disposed at the base of connection with the water supply pipe 2, and the flow path is switched by the flow path on-off valve. The tap water can be directly introduced into the water discharger 3 or can be led to the water conditioner 6 side described later. And by controlling the opening degree of the electromagnetic on-off valve provided on the downstream side of the flow path on-off valve from fully closed to fully open, water can be discharged at a desired momentum.
[0054]
The electromagnetic on / off valve is controlled by operating various switches 51 of the operation panel 5 disposed in the vicinity of the water discharger 3. In other words, a microcomputer (not shown) is connected to the operation panel 5 so that the electromagnetic on-off valve can be arbitrarily operated from fully closed to fully open via an electrical signal. 52 is a display unit composed of 7-segment LEDs, which enables the countdown display of the time until execution of automatic water discharge, which is the gist of the present embodiment, which will be described later. Alternatively, the opening / closing operation result of the electromagnetic opening / closing valve can be displayed.
[0055]
In the present embodiment, an opening / closing handle 32 and a temperature adjustment handle 33 are provided at the base of the water discharger 3 in order to enable water discharge by manual operation.
[0056]
Further, as described above, the water conditioner 6 including the electrolytic cell 60 that creates alkaline water and acidic water by electrolysis is installed in the storage portion 11 located below the sink 10, and the box The acidic water outlet 62a and the alkaline water outlet 62b of the electrolytic bath 60 housed in a water conditioner case 63 formed in a pipe shape are connected to the valve box 4 by piping.
[0057]
In addition, the water conditioner 6 in the present embodiment includes a water purifier 7 incorporating a hollow fiber membrane and activated carbon, and is held by a holder 7a provided on the side of the water conditioner case 63. And while connecting the water inlet 71 provided in the upper end of the water purification part and the flow-path switching valve of the said valve box 4, the water outlet 72 provided in parallel with the water inlet 71 and the water inlet 61 of the said electrolytic vessel 60 are connected. Communication connection.
[0058]
1 and 2, 12 is a drain pipe that connects the sink 10 and the sewer, 41 is a raw water pipe that connects the valve box 4 and the water inlet 71 of the water purification section 7, and 42 is the water purification section 7. Water purification pipe 43, 44, which connects the water outlet 72 and the water inlet 61 of the electrolytic bath 60, and the acid water outlet 62 a, the alkaline water outlet 62 b of the electrolytic bath 60 and the valve box 4, respectively. Electrolyzed water piping.
[0059]
The pipes 42, 43, and 44 are substantially connected to the electrolytic cell 60 via connector portions 63a, 63b, and 63c provided on the upper surface portion of the water conditioner case 63. 64 is a pressure switch, and 65 is a leg seat made of vibration-proof rubber provided on the lower surface of the water adjuster case 63.
[0060]
With such a configuration, when various switches 51 of the operation panel 5 are operated, tap water as raw water is discharged at a desired temperature and a desired amount of water, or alkaline water or acidic water obtained by electrolysis is selected with a desired amount of water. Therefore, it can be discharged from the water discharge tool 3.
[0061]
In addition, when either acidic water or alkaline water is selected and discharged from the water discharger 3, unselected electrolytic water is drained into the sink 10 through an electrolytic water discharge pipe (not shown). . Therefore, when alkaline water is selected and taken from the water discharger 3, the acidic water is drained to the sink 10, and the sink 10 can be washed. Of course, the drained water can be used as acidic water even in alkaline water spouting.
[0062]
In the undersink type water conditioner 6 including the water discharger 3 described above, the gist of the present embodiment is the flow path in the water discharger 3 and the water discharger 3, specifically the valve box 4. This is because an automatic washing function for automatically preventing water from spouting water accumulated on the upstream and downstream sides of the flow path opening / closing valve made of an electromagnetic valve disposed therein is added.
[0063]
That is, for example, for 3 days or more, if water is retained more than this, the water stays on the downstream side of the flow path opening / closing valve by regularly discharging water for a predetermined time at an interval shorter than the time at which miscellaneous bacteria may grow. When water is thrown away and new water is introduced and the user next takes water from the water discharger 3, control is performed so that no germs are included.
[0064]
3 and 4 are flowcharts relating to the automatic cleaning function of the water adjuster 6 according to the present embodiment.
[0065]
As shown in FIG. 3, when a water supply device is purchased and installed, and the power is turned on (100), the automatic water discharge start that is preset at the time of factory shipment, that is, the time until automatic cleaning is called from the backup device ( 200). The set time until automatic cleaning is performed is hereinafter referred to as “cleaning time”.
[0066]
Then, the cleaning time, that is, how many hours from now is displayed on the display unit 52 as a number (300). This cleaning time display process (300) is shown as a subroutine in FIG.
[0067]
In this embodiment, the factory cleaning time is 12 hours. Unless a new cleaning time is set as it is, automatic water discharge (automatic cleaning) is performed for 1 minute 12 hours after the power is turned on. In addition, automatic water discharge is performed regularly every 24 hours.
[0068]
In addition, in the water conditioner of the present embodiment, there are a mode for discharging raw water directly from a water discharger, a mode for discharging alkaline water, a mode for discharging acidic water, and a mode for discharging purified water. It is preferable that the mode is not a mode of discharging raw water. In the water discharge mode of alkaline water, acidic water, or purified water, it is possible to discharge the staying water in the water conditioner.
[0069]
Of course, it is also possible to automatically discharge water while electrolyzing. In this case, it is possible to store the usage history for each mode in advance, and set it to a mode that is less frequently used during automatic water discharge. It is possible to correct the usage gap and to reduce or eliminate the opportunity for cleaning by electrolysis of the electrolytic cell. Furthermore, the automatic water discharge is very effective if performed for a time corresponding to the difference in use frequency.
[0070]
On the other hand, when the up / down method setting button 53 provided on the operation panel 5 is operated to newly set the cleaning time (400), the cleaning time by the new setting is counted down, and the time becomes 0 to 0. The number 24 is displayed on the display unit 52 (500).
[0071]
As shown in FIG. 4, the flow of the cleaning time display process (300) is as follows. Until the automatic water discharge is performed, that is, while the automatic water discharge is not performed (310), the display unit 52 uses the 7-segment LED for cleaning. A countdown display in which the hour number decreases every hour (320), and when the time is up and automatic water discharge is performed (330), automatic water discharge is performed for 1 minute when automatic water discharge is performed on the display 52. Is displayed as “0” by a 7-segment LED (340).
[0072]
The process until the automatic cleaning will be described more specifically with reference to FIG.
[0073]
That is, when the water conditioner 6 according to the present embodiment is purchased and installed and the time when the power is turned on is 2:00 pm, the start time of automatic water discharge desired by the user can be 3:00 am For example, the user operates the setting button 53 to input “13” as the cleaning time. Then, the number “13” is displayed on the display unit 52 by the 7-segment LED, and the countdown display in which the number decreases every hour is started (FIG. 5A).
[0074]
For example, at 2:00 am when 12 hours have passed since the time has elapsed, since the countdown is proceeding, “1” is displayed on the display unit 52 (FIG. 5B). Therefore, it can be seen from the display unit 52 that automatic water discharge starts after one hour.
[0075]
Then, at the moment when 1 hour elapses and 2 am to 3 am, the number on the display changes from “1” to “0”, the time is up, and automatic water discharge from 3 am is executed for 1 minute. To do. Moreover, in order to display that the automatic water discharge is being executed, the “0” display continues for 1 minute (FIG. 5C).
[0076]
That is, since the number “0” itself indicating the time used in the display unit 52 that displays the countdown is a sign indicating that the target operation is being executed, it is possible to display that the automatic water discharge is being executed. There is no need to provide a special display unit separately.
[0077]
When the automatic water discharge for 1 minute is completed, a numerical value “24” indicating that the time until the automatic water discharge at 2 am on the next day, that is, 24 hours later, is displayed on the display unit (FIG. 5D). That is, the display of “24” actually continues for 59 minutes. Therefore, after 59 minutes, the display changes to “23” (FIG. 5 (e)) and sequentially displays “22”,..., “2”, “1” until the automatic water discharge at 2 am on the next day. Will change.
[0078]
Thus, when a limited short time of 1 minute during the automatic water discharge is displayed as “0”, and when the next cleaning time is displayed after the automatic water discharge ends, the actual water discharge is actually performed only for 1 minute. Although it is short, it is displayed with the number “24” indicating that it is 24 hours later, so that the user can intuitively recognize that automatic water discharge will be performed again after 24 hours. Therefore, it is very easy for the user to understand as a display method.
[0079]
In addition, as shown in FIG. 6, when it is set so that automatic water discharge is performed after 13 hours (400), a predetermined time (set as a cancellation time zone) before the set time, in this embodiment, 2 hours before If the normal water discharge operation is performed before (410), the automatic water discharge is canceled. As shown in the figure, if normal water discharge is performed approximately 70 minutes before the set time, “2” is displayed on the display unit 52 of the operation panel 5 at that time (420), and the time has elapsed since then. When the time set for performing automatic water discharge is reached, since the automatic water discharge is canceled, “24” indicating the cleaning time until the next automatic water discharge (430) is displayed on the display unit 52 (440).
[0080]
In other words, it is usually sufficient to perform automatic water discharge for preventing germ growth once a day or every two days, and when the cancellation time zone is set to 2 hours as described above, for example, this greatly affects the growth of germs. If a normal water discharge operation is performed during that time, even if the automatic water discharge set only 2 hours after the normal water discharge is canceled, the growth of germs can be sufficiently prevented.
[0081]
Further, as shown in FIG. 6, even if there is normal water discharge in a time zone other than the cancellation time zone (450), automatic water discharge is performed at the set time (460), and automatic water discharge is performed once a day. It will be done reliably. During the automatic water discharge at this time, “0” is displayed on the display unit 52 (470), and when the water discharge for one minute is completed, the display becomes “24” as described above.
[0082]
On the other hand, the above-mentioned cancellation time zone can be set as a long time such as 12 hours or 24 hours, for example. With such a setting, normal water discharge is performed within the cancellation time zone as long as normal use is performed. Since it is normal, automatic water discharge is rarely performed except when the user is away for a long period of time.
[0083]
Next, as another embodiment, a description will be given of a case where the execution timing of automatic water discharge can be set by calculating a use off time from the usage history of the water-circulating device.
[0084]
In this case, the water adjuster 6 is provided with an arithmetic device such as a microcomputer linked with the timer function and the operation panel 5, and by identifying and counting signals transmitted by operating the various switches 51, the water discharger 3 The number of water discharges, the discharge time, the interval from discharge to discharge, and the discharge frequency per fixed time are calculated, and the time zone with the fewest opportunities for water discharge is calculated and determined. The time to automatically discharge water is set automatically.
[0085]
Then, the cleaning time is displayed on the display unit 52 of the operation panel 5 from the time of the calculation until the set time of automatic water discharge. And as above-mentioned, after setting, automatic water discharge is performed at an interval of 24 hours.
[0086]
Further, similarly to the previous embodiment, a cancel time zone is provided, and when a normal water discharge operation is performed during this cancel time zone, automatic water discharge can be canceled.
[0087]
At this time, the total time of the water discharge operation performed in the cancellation time zone may be measured, and automatic water discharge may be canceled only when the total time is equal to or longer than the time required for cleaning (1 minute).
[0088]
By the way, as described above, when the automatic water discharge execution timing is set by calculating the off-use period from the usage history of the water supply device, for example, it is updated weekly from the latest usage history information calculated in units of one week. Can be done.
[0089]
By doing in this way, the timing of automatic water discharge can be always matched with a user's new lifestyle.
[0090]
In each of the embodiments described above, the automatic water discharge interval is 24 hours, but may be a multiple of 24 hours. For example, assuming an interval of 48 hours, automatic water discharge is performed at a predetermined time once every two days.
[0091]
As mentioned above, although this invention was demonstrated through the Example, application of this invention is not limited to a water conditioner etc., It is a water-equipment apparatus which comprises a water discharging tool like a water purifier, a hand-washer, a gargle, etc. Anything is fine.
[0092]
