DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power supply control device for a water heater for washing water and a heating toilet seat.

[0002]

2. Description of the Related Art In a hot water heater for washing water for local washing and a heating toilet seat in winter, the washing water or the toilet seat is always energized so as to maintain a predetermined temperature, but this consumes a large amount of energy. If a power saving switch is provided and the power saving switch is turned on, the power saving rate of the heater of the water heater or the toilet seat is reduced from that in the normal control to save power, and if a user is detected, the power is turned on. The rate is returned to the normal state, and the washing water or the toilet seat is returned to the set temperature.

[0003]

However, even if the duty ratio is returned to the normal state by detecting a person in the power saving state,
Since it takes time for the washing water and toilet seat to return to the set temperature, the user often feels cold.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and a purpose thereof is to provide a water heater for washing water and a power supply control device for a heated toilet seat, which saves power and does not feel cold. To provide.

[0005]

SUMMARY OF THE INVENTION Accordingly, the present invention accumulates time zone data of toilet use over a plurality of days from the output of the detection means for detecting use of the toilet, and sets the time to be energized based on the time zone data. An energization control device comprising an estimating means for estimating a zone, and energizing a water heater for washing water and a heating toilet seat based on the estimation result, wherein the estimating means is a time obtained by dividing 24 hours by a predetermined time unit. Set the level according to the past use results for each band, and for the time zone where the use results are at the predetermined level, the normal energization control is performed for the time zone before the predetermined time, and for the time zone where there is no use results, the power saving control Alternatively, it is characterized in that non-energization control is performed.

On the basis of the past use time data, the use time zone is predicted and the normal energization is performed. In addition, in order to perform the normal energization from a predetermined time before the use time zone, the normal use is performed. Even when used in a shifted time zone, the user does not feel cold, and in a time zone where there is no actual use, the power saving control or the non-energization control is performed, so that the power saving state can be reliably obtained.

[0007] The prediction means may be provided with a day of the week calendar function, and may ignore the use data for Saturday and Sunday and do not accumulate it in the time zone data. Since the holidays are holidays, the usage results on days with different life patterns are ignored, so that the prediction accuracy on weekdays does not decrease.

If the days of the week that are not accumulated in the time zone data by ignoring the use data are made variable, it is possible to deal with persons who are not holidays on Saturdays and Sundays.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to an example of an embodiment. Here, a local cleaning apparatus 1 provided with a cleaning means 10 shown in FIG.
The heater 20 of the washing water heater 2 and the heater 30 of the heating toilet seat 3 in FIG. Note that only one of them may be a control target. As a detecting means for detecting the use of the toilet, a switch S for detecting the seating on the toilet seat 3 is used here. The heaters 20 and 30 are controlled in a normal energized state or an energized state with a reduced energization rate (or a non-energized state) based on the prediction result of the prediction means.

[0010] The predicting means here collects usage data for each time zone obtained by dividing 24 hours into predetermined time units (here, 6 minutes), and based on the data, the time that will be used will be used. In this case, prediction is made for a zone. Here, data for the divided time zone is collected over a plurality of days. The operation will be described based on the flowchart of FIG. Note that x in the figure indicates a day, and y indicates a time zone. When 24 hours are divided into 6-minute units as described above, the value of y takes a value from 0 to 239.
Further, the y seating frequency counter is provided for each value of y.

First, a 6-minute timer is started at the same time as the operation of the apparatus, and it is detected from the output of the switch S whether or not there is a seat during that time. If there is a seat, the normal control (normal energization) state is set, and a value of 1 is given to the time zone of the day (for example, No. 0-6), and 3 is set to the value of the y seating frequency counter in that time zone. I do.

If no seating is detected, after a lapse of several minutes (for example, 3 minutes), the next time zone (x-
It is checked whether or not the value of (1, y + 1) is 1, and if it is not 1, a value of 0 is given for the simple zone at that day, and the value of the y seating counter in that time zone is decreased by 1.

After 6 minutes have elapsed, the value of y is increased by one, and when the value of the y seating counter is 0, the mode shifts to the power saving mode, and the value of the y seating counter is 1, 2 or 3. Sometimes, normal control is performed.

By repeating the above operation for 24 hours, for example, a value of 1 is given from the output of the seating switch S in the time zone of y = 6 on the day of x = 0, and y of y = 6
Assuming that the seating counter is set to 3, in a certain time zone (x = 1, y = 5) of the next day, even if the seating switch S is not on, the next time zone (x =
In the check routine of the value of (0, y = 6), the control is shifted to the normal control because the value of 1 is returned. By using the previous day's usage time zone as the predicted usage time zone and entering normal control several minutes before that, if there is actual usage during the predicted usage time zone,
It is something that the user does not feel cold.

The value of the y seating counter decreases every day unless the seating switch S is turned on during that time period. However, the value of 3 is set when the seating switch S is turned on. The time period used once is usually controlled as a predicted use time period for the next three days. However, if there is no re-use during the three days, it is determined that the first use is sudden after three days, and that time zone is determined to be a non-use time zone, and control is performed in the power saving mode. . y The value set in the seating counter indicates the level according to the usage record for that time zone. By updating this level assignment every day, the latest life pattern of the user is learned. That is, the predicted use time zone and the non-use time zone are predicted.

On Saturdays and Sundays whose life patterns are different from weekdays, as shown in FIG. 3, all the days are controlled normally, and the values of x and y and the value of the y seating counter are not updated. Good. By ignoring the usage situation on days where life patterns are different because it is a holiday, it is possible to prevent the accuracy of weekday predictions from deteriorating, and to use it in a time zone completely different from weekdays. There will be no.

Since there are some users whose holidays are not on Saturdays and Sundays, it is of course preferable to be able to set holiday days as shown in FIG.

Note that the time unit for dividing one day and the value set in the y-seating counter shown here are only examples, and are not limited to the above values.

Returning to normal power supply several minutes before the estimated use time is performed according to the value given for the next time zone of the previous day so as to match the latest life pattern. This may be performed according to the value of the y-seat counter in the time zone. Further, in the flowchart, the power saving mode is shown, but this may be a non-conduction mode.

[0020]

As described above, in the present invention, the time zone data of toilet use over a plurality of days is accumulated from the output of the detecting means for detecting the use of the toilet, and the time zone to be energized based on the time zone data. When power is supplied to the water heater for washing water and the heating toilet seat based on the prediction result, the prediction means calculates the past usage results for each time period obtained by dividing 24 hours into predetermined time units. Set the level according to, and for the time zone where the usage record is at the predetermined level, perform the normal energization control for the time zone before the predetermined time, and use the power saving control or the non-energization control for the time slot where there is no usage record Based on the data of the past use time, in addition to predicting the use time zone and performing the normal energization, the prediction is performed to perform the normal energization from a predetermined time before the use time zone. Even if it is used in a time zone slightly deviated from the usage time zone, it does not feel cold, and in the time zone where there is no use record, it is necessary to ensure the power saving state in order to use power saving control or de-energization control Can be done.

If the prediction means has a day calendar function and ignores the use data for Saturday and Sunday and does not accumulate it in the time zone data, it is a holiday, so it is a holiday and it is used on a day different in life pattern. Since the results are ignored, the prediction accuracy on weekdays does not decrease.

If the days of the week that are not used and are not stored in the time zone data are made variable, it is possible to cope with people who are not holidays on Saturdays and Sundays.
