Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a sanitary washing device.

[0002]

2. Description of the Related Art In a conventional sanitary washing device, a body casing containing a washing water discharge nozzle for discharging washing water is mounted on an upper part of a toilet bowl, and a toilet seat and a toilet seat cover are provided in front of the body casing. A sleeve-shaped operating section casing is connected to the side of the main casing while being arranged vertically rotatable.

[0003] Such a sanitary washing device comprises a washing water discharge unit for discharging washing water heated to a set temperature, a toilet seat heating unit for heating a toilet seat to a set temperature, and a dry air sending unit for sending dry air at a set temperature. With
A control unit for controlling each of these units,
And an operation unit for operating the control unit.

[0004] The set temperature of each unit can be set by the operation unit. Wash water having the set temperature set by the operation unit is discharged from the washing water discharge unit, or the set temperature set by the operation unit is set. Each unit is controlled by the control unit so that the toilet seat is heated by the toilet seat heating unit, or the drying air at the set temperature set by the operation unit is sent by the drying air sending unit.

In such a conventional sanitary washing device, each unit is energized from a time when it is not actually used, and is immediately turned on at the time of use so that the user can use the device comfortably at any time. Water discharge at the set temperature can be performed, and when the power saving button provided on the operation unit is operated, the control unit stores the past usage status and determines the usage frequency based on the storage result. The low time zone is learned, and in such a low usage time zone, at least a part of the washing water discharge unit, the toilet seat heating unit, and the dry air sending unit (a unit or a device such as a heat exchanger constituting the unit). The power supply is controlled to stop or reduce power supply to reduce power consumption to save power.

[0006] Such power saving control is, specifically, a control unit, in which the washing water discharge unit, the toilet seat heating unit, and the dry air sending unit are energized in preparation for use and when not in use. The presence or absence of use within a predetermined time is detected by the use presence / absence detection means, and the detection result obtained by the use presence / absence detection means is stored in a use presence / absence storage means such as a memory. Based on the data stored in the means, the power is conserved by stopping or reducing the power supply to the operating part during a time period when the frequency of use is low.

[0007]

However, in the sanitary washing device, the power supply may be temporarily interrupted on the way due to a power failure, cleaning, or absence for a long period of time, and power saving control may not be performed smoothly.

In this case, the storage data stored in the use / non-use storage means is completely erased before the interruption of the power supply, and the detection and use by the use / non-use detection means are performed immediately after the interruption of the power supply. It is conceivable to perform control so that the storage in the storage means is performed again from the beginning and learning is performed again.

However, such control does not cause a serious problem in a situation where the past stored data is hardly relied on, as in the case of a long-term absence. In a situation where even data is reliable to some extent, there is a possibility that accurate power saving control cannot be performed immediately after the interruption of power supply.

In addition, while the storage data stored in the use / non-use storage means before the interruption of the power supply is used as it is, the storage in the use / non-use storage means is continuously performed immediately after the interruption of the power supply. When an absolute reference time (for example, midnight) is reached by a timekeeping means such as a clock provided inside the unit or the attached remote controller, correction is made for the time during which power supply is interrupted, Control may be performed to perform learning based on the corrected stored data.

However, in such control, it is necessary to separately provide clocking means such as a clock provided inside the control unit or an attached remote controller and a power source such as a battery therefor, which not only increases the manufacturing cost but also increases the manufacturing cost. In addition, the user is forced to perform troublesome work such as battery replacement. In addition, when the power supply is interrupted for cleaning at a fixed time every day, the stored data is corrected only at the absolute reference time, so there is a gap in the stored data after the fixed time every day. There is a possibility that accurate power saving control cannot be performed.

[0012] Of the reasons for interruption of power supply, those due to power outages or long-term absence have very low occurrence frequency. Therefore, if power saving control is performed on the assumption of such interruption reasons, the occurrence frequency is the highest. There was a possibility that adverse effects would occur even when the cleaning was interrupted by regular cleaning.

Therefore, according to the present invention, it is possible to satisfactorily perform power saving control even if the power supply is interrupted due to cleaning, which occurs most frequently, among power supply interruptions. The purpose of the present invention is to provide a power saving control capable of coping with the interruption to some extent.

[0014]

That is, in the present invention,
Hygiene that stores past usage status, learns less frequently used time zones based on the storage results, and stops or reduces power to at least some devices during such infrequently used hours to save power. Even when the power supply is interrupted in the cleaning device, the usage status is continuously stored after the interruption, and power saving is performed according to the frequency of use without considering the time when the power supply is interrupted. did.

[0015] Further, an operating unit for supplying electricity even when not in use for use and a control unit for controlling the operating unit are provided, and the control unit detects the presence or absence of use within a predetermined time. And a use presence / absence storage means for storing a detection result obtained by the use presence / absence detection means, and an operating unit in a time period of low use frequency based on data stored in the use presence / absence storage means. In a sanitary washing apparatus that controls to save power by stopping or reducing the power supply to the power supply, when the power supply is interrupted, the control unit continues the storage data stored in the use / non-use storage unit until before the interruption. Immediately after the interruption, the detection result obtained by the use presence / absence detection means is continuously stored as storage data, and the use frequency is higher than the preset frequency regardless of the time when the power supply is interrupted. There were determined based on the stored data stored in used whether storage means a time zone, a low frequency of use time period was decided to control in order to perform the power saving by stopping or reducing the power supply to the actuating portion.

The control section further subdivides the predetermined time for detecting the use or non-use by the use / non-use detection means, detects the use or non-use within the subdivided time by the use / non-use detection means, The detection result obtained by the detection means is stored in the use presence / absence storage means, and further, when the power supply is interrupted, the storage data storing the presence / absence of use within the time segmented before the interruption. After that, whether or not it is used within the subdivided time after the interruption is continuously stored as storage data, and the frequency of use is lower than the preset frequency regardless of the time when the power supply is interrupted. The band is determined based on the storage data stored in the use presence / absence storage means, and control is performed to save power by stopping or reducing the power supply to the operating unit during a time period of low use frequency.

The control unit changes the setting frequency to a low value when the power supply is interrupted.

In the sanitary washing device 1 having the above structure, each unit (the washing water discharge unit 8, the toilet seat heating unit 9 and the toilet seat heating unit 9) is not used until the user can use it comfortably at any time. The drying air delivery unit 10) is energized, and the washing water at the set temperature set by the operation unit 12 is immediately discharged from the washing water discharge unit 8 at the time of use, or the toilet seat heating unit is set to the set temperature set by the operation unit 12. The control unit 11 controls the units 8, 9, and 10 so that the toilet seat 4 is heated at 9 or the drying air at the set temperature set by the operation unit 12 can be sent by the drying air sending unit 10.
As described above, the sanitary washing device 1 according to the present embodiment includes the washing water discharge unit 8, the toilet seat heating unit 9, and the dry air sending unit 10 as the operation unit that prepares for use and conducts electricity even when not in use. And a control unit 11 as a control unit for controlling the operation unit.

In addition, in the sanitary washing device 1 according to the present embodiment, when the power saving button 58 provided on the operation unit 12 is operated, the control unit 11 stores the past usage status, and the storage result is stored in the storage result. The less frequently used time zone is learned based on this, and the power to the washing water discharge unit 8, the toilet seat heating unit 9, and the dry air sending unit 10 is stopped or reduced in such a less frequently used time zone, and the consumption of the entire apparatus is reduced. Control is performed to save power by reducing power.

That is, the control unit 11 controls the timer 41
A predetermined time (45 minutes in the present embodiment) is measured by the use presence / absence detection means 39 to detect whether or not the apparatus has actually been used within the predetermined time, and the detection result is stored in the use presence / absence storage means 40. The time period in which the frequency of use is lower than the preset frequency is determined based on the storage data 66 in the use presence / absence storage means 40, and in the time period in which the frequency of use is low, the operating unit (the washing water discharge unit 8, the toilet seat heating, Control is performed so as to save power by stopping or reducing the power supply to the unit 9 and the drying air delivery unit 10).

As shown in FIG. 11, the stored data 66 is stored in 32 time zones (5:30 to 6:01) every 45 minutes for one day.
5 minutes, 6:15 to 7:00, 7:00 to 7:45, ...
4:00 to 4:45, 4:45 to 5:30), and the first time zone (5:30 to 6:15) one day before (the day before) to perform power saving control D (1,1) is used as data indicating whether or not the data is used, and the second time zone (from 6:15 to 7
The data indicating the use at time (D) is D (1,2), and the first time period (5: 3) two days before the power saving control is performed.
(0 to 6:15)
(2,1), and D (2,2) is the data indicating the use or non-use in the second time zone (6:15 to 7:00).
Data indicating the presence or absence of use in the n-th time zone m days before the power saving control is performed is represented as D (m, n). In this embodiment, data up to eight days before the power saving control is performed is stored.

Here, the data indicating the use or not is shown in FIG.
As shown in the equation (1), when data is actually used in each time zone, each data is set to 1. On the other hand, when it is not actually used in each time zone, each data is set to 1. The data is set to 0.

The stored data 66 divides a day into 32 time zones every 45 minutes, and determines whether or not power saving is performed (whether or not power is supplied) in each time zone of the day on which power saving control is performed. S (1), S (2), S (3),..., S (31),
S (32) is set, and the data indicating whether or not to perform the power saving is determined based on the data indicating whether or not the power is used in two adjacent time zones from eight days to one day before performing the power saving control. Like that. Therefore, the time zone in the data indicating whether or not to save power is shifted by 22 minutes and 30 seconds from the time zone in the data indicating the use or non-use. Specifically, the time zone in the data indicating whether or not to save power is from 5:52:30 to 6:37:30, 6
Hour 37: 30-30: 22: 30,7: 22: 30-8: 7: 30, ... 4: 22: 30-5: 7
It is divided into 32 divisions of minutes 30 seconds, 5: 7: 30 and 5:52:30.

Here, the data indicating whether or not to perform power saving is obtained by performing power saving control as shown in equation (2) in FIG.
A total of 16 data indicating whether or not the data is used in two adjacent time zones from one day before to one day before is calculated, and if the total is used more than a predetermined set frequency k, power saving is performed. , Which indicates not to perform
When the sum is used less than a predetermined set frequency k, it is set to “O” indicating that power saving is performed. The setting frequency k is set to 4, for example, when setting so that power saving is not performed in a time zone used four or more times in a total of 16 time zones. still,
For convenience of calculation, D (i, 1) is set to D (i, 33).

A description will be given based on a specific example. As shown in FIG. 12, when the detection result by the use / non-use detection means 39 is stored in the use / non-use storage means 40 at intervals of 45 minutes using the timer 41, the storage data 66 is stored. , 8 days before is used only in the third time zone (7:00 to 7:45) (that is, D (8,3) = 1), and 7 days before is used in the fourth time zone (7:45 ８8:30) only (ie, D (7,4) = 1), and six days ago used in the second, third, and fifth time zones (ie, D (6,2)) = 1, D
(6,3) = 1, D (6,5) = 1) 5 days before is used only in the fourth time zone (ie, D (5,4) = 1), 4
The day before is used only in the fifth time period (ie, D (4,5) = 1), and the day before is used only in the third time period (ie, D (3,3) = 1). Two days ago are used in the third and fourth time zones (ie,
If D (2,3) = 1, D (2,4) = 1), and one day before is used only in the fourth time zone (ie, D (1,4) = 1), the frequency of use is When controlling so as not to save power when the number of times is four or more (that is, when the setting frequency k = 4)
From the equation (2) in FIG. 11, the second, third, and fourth time zones (that is, 6:37:30 to 7:22:30,
7:22:30-8:30:30, 8:30:30-
In each time zone of 8:52:30, power saving is not performed, and power saving is performed in other time zones (that is, S
(1) = “O”, S (2) = “X”, S (3) = “X”, S (4) =
“X”, S (5) = “O”, S (6) = “O”).

Here, when the frequency of use is twice or more, control is performed so as not to save power (that is, the set frequency k =
In the case of No. 2, the second, third, and fourth time zones (that is, from 6:37:30 to 7:02) are obtained from Expression (2) in FIG.
In addition to the 2:30 minutes, 7:22:30 to 8:30:30, 8:30:30 to 8:52:30, the fifth time period (that is, 8:30:30 to 8:52:30). 1:52:30-9: 3
7 minutes and 30 seconds), power is not saved, and power is saved in other time zones (that is, S (1) =
“O”, S (2) = “X”, S (3) = “X”, S (4) =
“X”, S (5) = “X”, S (6) = “O”).

As described above, when the setting frequency k is changed to a low value, the time period during which the power saving control is not performed increases (in the above-described embodiment, the fifth time period is the time when the setting frequency k = 4. However, at the setting frequency k = 2, the power saving control is not performed.) That is, by changing the setting frequency k to a lower value, the time period during which the power saving control is not performed increases, and in such a time period, water is discharged at a comfortable temperature when the user uses the device. This eliminates the possibility of giving discomfort to the person. In other words, the power saving control has the effect of reducing power consumption by performing power saving, but on the contrary, it gives the user unpleasant feeling when used unexpectedly during the time of power saving. In order to prevent the user from feeling uncomfortable as much as possible, it is desirable to control the time period during which the power is saved to a safe side, that is, to increase the time zone. Although a specific time has been described above for convenience, this time is a time recognized by the control unit 11 and cannot be matched with an actual time. Therefore, if the power supply is interrupted halfway as described below,
Since the time in the control unit 11 does not advance, the actual time is shifted at least by the time during which the power supply is interrupted. The present embodiment has a feature in the control when the power supply is interrupted during the power saving control.

That is, in this embodiment, the control unit 11
However, when the supply of power is interrupted, the storage data 66 stored in the use / non-use storage means 40 before the interruption of power supply is stored.
Immediately after the interruption of the power supply, continuously stores the detection result obtained by the use presence / absence detecting means 39 as storage data 66, regardless of the time at which the power supply was interrupted, than the preset frequency k. A time zone with a low use frequency is determined based on the stored data stored in the use presence / absence storage unit 40, and in a time zone with a low use frequency, power supply to each of the units 8, 9, and 10 is stopped or reduced to save power. Control.

More specifically, as shown in FIG. 13, if the power supply is interrupted for cleaning in the (n + 1) th time zone before the m-th day, the use / non-use storage is performed before the power supply is interrupted. The storage data 66 stored by the means 40, here, the storage data 66 up to D (m, n) is used.
When the interruption of the power supply is finished, that is, when the power supply is restarted, the detection by the use presence / absence detection means 39 is restarted again. The detection result is continuously stored as storage data 66 (here, D (m, n + 1), D (m, n +
2), ...).

As described above, in the present embodiment, even when the power supply is interrupted, the usage status is continuously stored after the interruption, so that the past stored data can be stored as in the case of a short-time power failure or cleaning. In situations where the power supply 66 is still reliable to a certain degree, accurate power saving control can be performed immediately after the power supply is interrupted by effectively utilizing the reliable data stored up to that point. Even if the interruption is caused by the above, it is possible to cope to some extent by utilizing the reliable storage data 66 up to that time.

In addition, since power saving is performed according to the frequency of use without considering the time when power supply is interrupted,
Even if a special device such as a timing unit is not separately provided, that is, without causing an increase in manufacturing cost, even if an interruption due to a short-time cleaning which is assumed to occur most frequently among power supply interruption reasons occurs. , Power saving control can be performed well.

As described above, according to the present embodiment, when the power supply is interrupted, the use presence / absence detection means 39 immediately obtains the storage data 66 stored in the use presence / absence storage means 40 immediately before the interruption. The obtained detection result is continuously stored as storage data 66, and the time zone whose usage frequency is lower than the preset setting frequency k is stored in the usage presence / absence storage means 40 regardless of the time when the power supply is interrupted. It is determined based on the data 66, and in the time of infrequent use, control is performed to save power by stopping or reducing the power supply to each unit 8, 9, 10, so special devices such as timekeeping means Without any additional provision, i.e., without incurring an increase in manufacturing costs, to ensure good power saving control even if a short-term cleaning interruption is assumed to occur most frequently among the reasons for interruption of power supply. Can be , It is possible to perform power saving control which can be interrupted by a low power loss or long-term absence of generation frequency corresponding to a certain extent be caused.

In particular, if the control unit 11 controls so as to change the set frequency k to a lower value as described above when the power supply is interrupted, the time period during which the power saving control is not performed increases, In such a time period, when the user uses the apparatus, water is discharged at a comfortable temperature, and the user is not likely to feel discomfort. Will be able to do it.

In the above embodiment, as described with reference to FIG. 13, when the power supply is interrupted for cleaning in the (n + 1) -th time zone before the m-th day, the power supply before the interruption is stopped. Since the storage data 66 previously stored in the use presence storage means 40 is stored in the use presence storage means 40, and the detection by the use presence detection means 39 is restarted again after the interruption of the power supply ends. , The n-th storage data 66
The storage data 66 after that (D (m, n)) is shifted by the time from the time immediately after the storage of (D (m, n)) to the end of the interruption of the power supply (the time indicated by the symbol t1 in FIG. 13).

If the interruption of the power supply immediately after the start of the storage of the (n + 1) -th storage data 66 (D (m, n)), there is almost no adverse effect on the power saving control, but the (n + 1) -th storage data 66 Immediately before the end of storing (D (m, n)), a large shift occurs. Therefore, in order to perform good power saving control corresponding to such a case, the control unit 11 further subdivides a predetermined time (for example, 45 minutes) for detecting use or non-use by the use / non-use detection means 39, and subdivides the time. The use presence / absence detection means 39 detects the use presence / absence within the set time (for example, 1 minute), and the use result presence / absence storage means 40 stores the detection result obtained by the use presence / absence detection means 39.

That is, as shown in FIG. 14, when the use presence / absence detection means 39 detects the n-th storage data 66 (D (m, n)) m days before, the timer 41 uses the timer 41 for one minute. The detection result detected by the use presence / absence detection means 39 at intervals is divided into subdivided data 67 (d (m, n, 1), d (m, n, 2), d (m, n, 3),.
d (m, n, 44) and d (m, n, 45)) are stored in the use presence / absence storage means 40. Further, as shown by the equation (3) in FIG. The use presence / absence storage means 40 determines that the use has been performed in the time zone (45 minutes), and stores 1 as the storage data 66 (that is, D (m, n) = 1). When the sum total of the data 67 is 0, it is determined that the use has not been performed in the time zone (45 minutes), and the use presence storage means 40 stores 0 as the storage data 66 (that is, D (m, n) ) = 0). In this case, the data indicating whether or not the data is used is set to 1 when the data is actually used in each of the subdivided time zones (that is,
d (m, n, h) = 1) On the other hand, if no data is actually used in each time zone, each data is set to 0 (that is, d (m, n, h) = 0). ).

More specifically, as shown in FIG. 15, the power supply is turned off only for a certain time (time indicated by reference symbol t2 in FIG. 15) for cleaning 10 minutes after the (n + 1) -th time zone before the m-th day. When the supply is interrupted, the storage data 66 stored in the use presence storage means 40 immediately before the interruption of the power supply, here, d (m, n + 1, 1) to d (m, n + 1) , 10) is stored in the use presence / absence storage means 40, and when the interruption of the power supply is finished, that is, when the power supply is resumed, the detection by the use presence / absence detection means 39 is restarted again. Immediately after the supply is interrupted, the detection result obtained by the use presence / absence detection means 39 is continuously stored as storage data 66 (here, d (m, n
+1,11) to d (m, n + 1,45), D (m, n + 2)).

As described above, the predetermined time for detecting the use or non-use by the use / non-use detection means 39 is further subdivided, and the use / non-use within the subdivided time is detected by the use / non-use detection means 39 and the same use / non-use is detected. By controlling the detection result obtained by the detection means 39 to be stored in the use presence / absence storage means 40, the segmented data 67 (here, d ( m, n + 1,1)-d
(m, n + 1, 10)) can be effectively used as it is, and only the time from the start of the interruption of the power supply to the end of the interruption of the power supply (the time indicated by reference numeral t2 in FIG. 15) is stored data 66. Therefore, the shift of the stored data 66 due to the interruption of the power supply can be made as small as possible, whereby accurate power saving control corresponding to a longer interruption time can be performed. .

Even in this case, if the control unit 11 controls to change the set frequency k to a lower value as described above when the power supply is interrupted, the time period during which the power saving control is not performed increases. However, during such a time period, water is discharged at a comfortable temperature when the user uses the device, and there is no possibility that the user will feel uncomfortable. Control can be performed.

In order to verify the effectiveness of the above-described power saving control, it is assumed that the power supply was interrupted at about 10:00 (actual time) every day for only 10 minutes due to cleaning or the like. FIGS. 16 and 17 show the results of the power saving control in the case where the operation is performed for 5 minutes at 7:15 (actual time).
Shown in 16 and 17 show the usage status and the power saving control result up to the eighth day after the start of the verification. The usage status is "O" or "X"("O" if used, "X" if not used) at 5 minute intervals on each day from 8 days to 1 day before the verification date .). In addition, the power saving control results are displayed in each time zone (45 minutes).
When power saving is not performed, the arrow is shown by a solid line, and when power saving is performed, it is shown by a dotted arrow. In the figure, the top time indicates the actual time (absolute time).

First, when the set frequency k is set to 4, that is, 4 times are set in two adjacent time zones (90 minutes) in the past 8 days.
FIG. 16 shows a case in which power saving is not performed after use more than once.

As shown in FIG. 16, first, on the first day, there is no interruption of the power supply in the past eight days, so that there is no shift in the stored data 66, and frequently used from 7:10 to 7 Power saving is not performed for 90 minutes including 15:00 (actual time).

On the second day, the stored data 66 is shifted by 10 minutes due to the interruption of the power supply for 10 minutes on the previous day, and the time period during which power saving is not performed is also shifted by 10 minutes. Still, power saving is not performed for 90 minutes including the frequently used 7:10 to 7:15 (actual time).

Similarly, on the third day, the stored data 66 and the time period during which power saving is not performed are shifted by 20 minutes, but include the frequently used time 7:10 to 7:15 (actual time). Power saving is not performed for 90 minutes, and on the fourth day, the stored data 66 and the time period during which power saving is not performed are shifted by 30 minutes, but frequently used from 7:10 to 7:15 (actual Power saving is not performed for 90 minutes including the time), and the storage data 66 and the time period during which power saving is not performed are shifted by 40 minutes on the fifth day, but frequently used from 7:10 to 7 Hour 1
Power saving is not performed for 90 minutes including 5 minutes (actual time).

On the sixth day, the stored data 66 and the time period during which power saving is not performed are shifted by 50 minutes, and the time period after 7:10 to 7:15 (actual time) frequently used is changed. The power saving is not performed in 90 minutes, and the power saving is performed in the actual use time (7:10 to 7:15).

Next, on the seventh day, the stored data 66 and the time period during which power saving is not performed are shifted by 60 minutes.
Power saving is not performed for 135 minutes including the hour from 10:07 to 7:15 (actual time), and on the eighth day, the stored data 66 and the time period during which power saving is not performed are shifted by 70 minutes, Frequently used from 7:10 to 7:15 (actual time)
Power saving is not performed for 135 minutes including.

As described above, by performing the above-described power saving control, even if the power supply is interrupted for a short time (10 minutes) every day due to cleaning or the like that is likely to actually occur, almost all It can be seen that there is no effect, and good power saving control is performed in the time zone that is actually frequently used.

According to the verification result shown in FIG. 16, power is saved in the actual use time on the sixth day. However, as described above, the setting frequency k is changed to a low value. It can be solved by.

That is, when the setting frequency k is 2, that is, two adjacent time zones (90 minutes) in the past 8 days
FIG. 17 shows a case where power saving is not performed when the device is used twice or more.

As shown in FIG. 17, first, on the first day, there is no interruption of the power supply in the past eight days, so that there is no shift in the stored data 66 and the frequently used 7: 10-7. Power saving is not performed for 90 minutes including 15:00 (actual time).

On the second day, the stored data 66 is shifted by 10 minutes due to the interruption of the power supply for 10 minutes the previous day, and the time period during which power saving is not performed is also shifted by 10 minutes. Note that power saving is not performed only for 90 minutes including frequently used from 7:10 to 7:15 (actual time). Similarly, on the third day, the stored data 66 and the time period during which power saving is not performed are shifted by 20 minutes, but 90 minutes including frequently used from 7:10 to 7:15 (actual time) On the fourth day, the power saving is not performed, and the stored data 66 and the time period during which the power saving is not performed are shifted by 30 minutes, but frequently used from 7:10 to 7:15 (actual time) The power saving is not performed for 90 minutes including the time, and the storage data 66 and the time period during which the power saving is not performed are shifted by 40 minutes on the fifth day, but frequently used from 7:10 to 7: 1
Power saving is not performed for 90 minutes including 5 minutes (actual time).

On the sixth day, the stored data 66 and the time period during which power saving is not performed are shifted by 50 minutes, but the time period during which power saving is not performed increases, and the frequently used time period is 7:10. Power saving is not performed for 135 minutes including the time from 7:15 (actual time), and the actual usage time (7
(10: 10-7: 15), power saving was not performed.

Next, on the seventh day, the stored data 66 and the time period during which power saving is not performed are shifted by 60 minutes, but include the frequently used 7:10 to 7:15 (actual time). 1
Power saving is not performed for 35 minutes, and on the 8th day, the stored data 66 and the time period during which power saving is not performed are shifted by 70 minutes, but frequently used from 7:10 to 7:15 (actual The power saving is not performed for 135 minutes including the time of ().

As described above, by changing the setting frequency k to a lower value, the time period during which the power saving control is not performed increases (in the above specific example, the time period increases from 90 minutes to 135 minutes). When the user uses the apparatus, water is discharged at a comfortable temperature and the like, and there is no risk of giving the user uncomfortable feeling. This makes it possible to perform more comfortable power saving control for the user. Become like The change of the set frequency k may be gradually changed to a lower value every time the power supply is interrupted. If the power supply has not been interrupted for a predetermined period, the set frequency k may be gradually changed to a higher value.
