[First Embodiment]

FIG. 1 shows an example of an electronic device according to the first embodiment.

The electronic device 2 of this embodiment utilizes the water level detection of the bathtub for the management of bathing. In this case, bathing is a state in which the water level of the hot water in the bathtub is rising by the bather. The electronic device 2 may be, for example, either a water heater control device or a water heater remote control device (hereinafter referred to as “remote control”), or may be both a water heater control device and a remote control device. The electronic device 2 is provided with a processor 4.

The processor 4 manages the bathing of the bather by executing the bathing management program. The processor 4 functions as a bathing determination means, a bathing time determination means, and an output means.

The bathing determination determines the start of bathing by the bather by taking in the water level detection output of the bathtub from the water level sensor 6.

The bathing time determination determines whether the continuous bathing time of the bather has reached the reference time. This continuous bathing time is expressed, for example, by the total time from the start of bathing to the time of soaking in the hot water in the bathtub. A timer 12 connected to the processor 4 is used to measure the duration. The timer 12 is an example of a means for measuring the continuous bathing time. Since the information indicating that the continuous bathing time of the bather has reached the reference time is an example of the information indicating the bathing state of the bather, this bathing time determination is a state determination means for determining the bathing state of the bather. This is an example. In this bathing time determination, it is determined whether or not the person is taking a bath by detecting the water level of the bathtub, and it is determined whether to measure the continuous bathing time or to end the measurement.

The output means outputs the notification information based on the determination result of the bathing time determination. The notification information indicates, for example, that the continuous bathing time of the bather has reached the reference time. This notification information is displayed on a display unit 8 such as a display connected to the processor 4, or is notified as a melody sound or a guidance sound by a notification unit 10 including a voice output means such as a speaker. This information may be given to the bather who is taking a bath, or may be given to a person other than the bather who is away from the bathroom.

For example, a pressure sensor may be used for the water level sensor 6. According to this pressure sensor, the water level of the bathtub is detected by detecting the water pressure of the bathtub. This detected water level is taken into the processor 4 as water level detection information. The water level sensor 6 is connected to, for example, a bathtub, a hot water supply pipe of a bathtub, or a circulation pipe for circulating bathtub water.

FIG. 2 shows an example of the time change of the water level of the bathtub.

If the bather enters the bathtub at time t11, the water level change ΔWL1 occurs. That is, when a bather starts bathing, a large rise in water level occurs. If the bather becomes quiet after bathing, the fluctuation of the water level at the time of bathing ends at this time t12. Assuming that the bather is in a static state in the bathtub until time t13, the change in the water level becomes a predetermined level or less in the bather's static time Ts. On the other hand, if the bather is in a moving state from time t13 to time t14, the water level change exceeds a predetermined level at the bather's moving time Tm. If the bather leaves the bathtub at time t14, the water level change ΔWL2 occurs. That is, when the bather finishes bathing, a large decrease in water level occurs.

The processor 4 monitors the water level, and if it detects the water level change ΔWL1, it determines that the bathing has started, and if it detects the water level change ΔWL2, it determines that the bathing has ended, it can determine the start and end of the bathing.

FIG. 3 shows a bathing management processing procedure. This treatment procedure is an example of the bathing management program of the present invention.

In the processing procedure shown in FIG. 3, the water level detection information is acquired (S11), it is determined whether the person is taking a bath (S12), and if the bathing is started or the bathing state continues (YES in S12), the bathing is continued. The time is measured (S13), and it is determined whether the continuous bathing time ≥ the reference time (S14).

If the continuous bathing time ≥ the reference time, (YES in S14). The notification information is output (S15), and the process returns to S11. If the continuous bathing time is less than the reference time (NO in S14), the process returns to S11.

If the bathing is completed or not in the bathing state in S12 (NO in S12), the measurement of the bathing time is finished (S16), and the process returns to S11. The S11 to S16 are repeatedly processed, and when the bathing is started, the continuous bathing time is measured until the bathing is completed.

According to this processing procedure, notification information is output when the continuous bathing time exceeds the reference time after the start of bathing.

<Actions and effects of the first embodiment>

According to the embodiment described above, the following actions and effects can be obtained.

Since the bathing time is automatically managed, the bather is freed from self-management such as bathing time, can take a comfortable bath, and the degree of freedom of bathing is increased.

If the notification information is output in the bathroom, it will be a notification (alert) of the bathing time to the bather, and it is possible to encourage the bather to get out of the bathtub. In addition, if the bathing time is output by notifying outside the bathroom such as the kitchen, it will be a notification (notification) to those other than the bather, and it will be an opportunity to confirm the safety of bathing such as abnormal bathing. can.

If both the water heater control device, the water heater remote control device, or the water heater control device and the remote control are used, bathing management can be performed by the detection output of the water level sensor of the water heater.

If the bathing time exceeds the standard time, the bather is notified, so that long-term bathing can be prevented. In addition, even if the bather falls asleep, an alert is issued after the bathing time exceeds the reference time, so that the bather can be awakened from the doze and the safety of bathing is enhanced.

<Modified example of the first embodiment>

(1) An example of making a bathing judgment by detecting the water level is shown, but a bathing person may be detected by a human body sensor such as an infrared sensor, and the bathing judgment may be made by detecting the human body. The bathing determination may be made based on the bathing sound. Further, the bathing determination may be made based on a plurality of pieces of information using a plurality of detection means. If a plurality of detection means are used, the accuracy of determination can be improved.

(2) During bathing, the display unit 8 may display whether the bather is in a moving state or in a quiet state. For this display, the static time Ts and the moving time Tm described above may be determined by the processor 4 using the detection result of the water level sensor.

(3) The continuous bathing time of the bather is not limited to the entire time from the start of bathing to the time of being immersed in the hot water in the bathtub, for example, the continuous time from the start of bathing, the continuous time after the start of bathing, and the continuous bathing time. It may be the number of times. The duration is represented, for example, by the duration of the bather's static or dynamic state. That is, the detection result of the water level sensor 6 may be used to determine the dynamic state or static state of the bather by the processor 4, and the duration of the static state or the duration of the dynamic state of the bather may be compared with the reference time. .. If the notification information is generated when the bather has been quiet for a long time, the notification information can function as an alert for the bather's long-term thoughts and dozing.

As an example, the display of the elapsed bathing time is displayed blinking on the clock display unit 166 of the bathroom remote controller 30 as shown in the bathing time display screen 164 shown in FIG. 25. When the melody sound stops, the display of the elapsed bathing time is returned to the clock display. This display of the elapsed bathing time enables the bather to recognize the bathing time and eliminates the need for self-management.

<Data communication>

FIG. 26 is a sequence diagram showing an example of bathing management.

When the setting operation to set the bathing notification function to "ON" is performed on the remote controllers 30 and 32 (S71), the bathing notification function ON is transmitted to the control unit 40 by the output of the "bathing notification on / off" signal "1". (S72). By this transmission, the bathing notification function becomes "on".

When the bath automatic key 102 is operated on the remote controllers 30 and 32 (S73), the "automatic" signal ON is transmitted to the control unit 40 (S74), and the automatic hot water filling operation is started (S75). When the automatic hot water filling operation is completed (S76), the control unit 40 transmits a "heat retention" signal ON to the remote controllers 30 and 32 (S77), and the remote controllers 30 and 32 emit a voice indicating boiling and "heat insulation". Is displayed (S78). This vocalization is an example of voice output.

When the automatic hot water filling operation is completed (S76), the bathing notification function is enabled in the control unit 40 (S79).

When the control unit 40 detects bathing (S80), the above-mentioned "in bathing" signal "1" transmits to the remote controllers 30 and 32 that there is bathing (S81). In response to this signal, the kitchen remote controller 32 turns on the bathing display (S82), that is, the kitchen remote controller 32 switches to the bathing display screen 158.

When the control unit 40 determines that the set time of the bathing notification timer has elapsed (S83), the signal "1" indicating "set time elapsed" is generated by the above-mentioned "FC notification" data 140 and "MC notification" data 142. It is transmitted to the remote controllers 30 and 32 (S84). In response to this signal, the bathroom remote controller 32 utters a melody sound (S85).

When the control unit 40 determines that 5 [minutes] have elapsed from the elapse of the set time of the bathing notification timer (S86), the "FC notification" data 140 and the "MC notification" data 142 indicate "5 minutes have passed". "1" is transmitted to the remote controllers 30 and 32 (S87). In response to this signal, the bathroom remote controller 32 utters a melody sound (S88). The output of the signal indicating "elapsed of 5 minutes" is repeated until it is determined that the bathing is completed, that is, the bathing is completed (S89, S90, S91).

When the control unit 40 determines that the bather has taken a bath (S92), the "no bathing" signal is transmitted to the remote controllers 30 and 32 by the "during bathing" signal "0" (S93). In response to this signal, the kitchen remote controller 32 turns off the bathing display 160 (S94).

When the control unit 40 determines the drainage of the bathtub 26 (S95), the bathing notification function is shifted to the prohibited state (S96).

According to such a sequence, the kitchen remote controller 32 can display that the bather is taking a bath, and the bathroom remote controller 30 can utter a melody sound indicating the passage of the set time or the passage of 5 [minutes].

<Outline of bathing management process>

FIG. 27 shows an example of an outline of the processing procedure of the bathing management process. This treatment procedure is an example of the bathing management program of the present invention.

In this processing procedure, it is determined whether or not the automatic hot water filling operation is completed (S101). If it is after the end of the automatic hot water filling operation (YES in S101), it is determined whether the water level of the bathtub 26 is equal to or higher than the measurable water level (S102). If the water level is above the measurable level (YES in S102) and there is no bathing (YES in S103), the process proceeds to S104. note that. In the first judgment after the end of automatic hot water filling, it is judged that there is no bathing.

If the automatic hot water filling operation is not completed in S101 (NO in S101), that is, if the automatic hot water filling operation is continuing or the automatic hot water filling operation is not performed, S101 is repeated until the automatic hot water filling operation is completed. If the water level is not higher than the measurable water level in S102 (NO in S102), the process returns to S101 and repeats S101 and S102.

In S104 and S105, the start of bathing is determined. If an increase in water level is detected (YES in S104) and the increased water level is equal to or higher than the set bathing threshold value (YES in S105), it is determined that the bathing state has been started and the bathing has started, and the kitchen remote controller 32 is used to take a bath. The middle display 160 is turned on (S106), and the process returns to S102. This bathing threshold is set to, for example, a water level corresponding to a water volume of 16 [liters] (above the water level before bathing). If the rise in water level is not detected in S104 (NO in S104), the process returns to S102 instead of the bathing state. If the water level raised in S105 is less than the set bathing threshold value (NO in S105), the process returns to S102 instead of the bathing state.

If the person is taking a bath in S103 (NO in S103), the process proceeds to S107. In S107 and S108, the end of bathing is determined. If a drop in water level is detected (YES in S107) and the lowered water level is less than the set de-bath threshold value (YES in S108), it is determined that the bathing is completed, not in the bathing state, and the kitchen remote controller 32 determines. The bathing display 160 is turned off (S109), and the process returns to S102. This bathing threshold is set to, for example, a water level corresponding to a water volume of 15 [liters] (below the water level during bathing). If the water level lowered in S108 is not less than the set debath threshold value (NO in S108), the process returns to S102.

If the water level drop is not detected in S107 (NO in S107), the bathing timer 80 is counted (S110), and if the set time elapses (YES in S111), the bathroom remote controller 30 utters a melody sound (S112). Return to S102. If it is within the set time in S111 (NO in S111), the process returns to S102.

According to such a treatment procedure, since the start and end of bathing are determined by the water level detection, it is possible to notify whether or not the bathing is in progress by turning on or off the bathing display 160. In addition, the passage of bathing time can be notified by uttering a melody sound.

<Bath display processing>

FIG. 28 shows an example of the processing procedure of the bathing display processing. This processing procedure is an example of the bathing display processing of the bathing management program of the present invention. In FIGS. 28 and 29, reference numeral a and reference numeral b are connectors representing a connection between flowcharts. In this processing procedure, a "bathing" signal is transmitted.

In this processing procedure, when the automatic hot water filling operation is completed (YES in S121), the initial value of the water level before bathing is stored in the data storage unit 92, and the “during bathing” signal is turned off (S122).

If the circulation pump 42 is stopped (YES in S123) and the bathtub 26 is not being poured (YES in S124), it is determined whether the water level of the bathtub 26 is equal to or higher than the reference water level + the additional water level (S125). The reference water level is, for example, the lower limit of the water level monitoring of the bathtub 26. The added water level indicates the amount of water added to the standard water level, and the water level may be such that the water level does not fall below the standard water level when the bather leaves the bathtub 26 after bathing. For example, the water level is 15 [ The water level is equivalent to [liter].

If the water level is equal to or higher than the reference water level + the additional water level (YES in S125), the water level is monitored (S126). That is, the water level monitoring is stopped by S123 and S124 while the circulation pump 42 is operating or pouring. The S123 and S124 may be used to stop the timers 80 and 82. For example, the timers 80 and 82 are stopped during the operation or pouring of the circulation pump 42.

In the water level monitoring (S126), the water level is sampled. The average data of the intake water level obtained by sampling is used for water level monitoring. For this average data, for example, 5 [second] average data of the water level information captured every 0.5 [second] can be used.

In S121, if the automatic hot water filling operation is not completed, that is, if the automatic hot water filling operation is continued or the automatic hot water filling operation is not performed (NO in S121), S121 is repeated.

If the circulation pump 42 is operating in S123 (NO in S123), S123 is repeated until the circulation pump 42 is stopped. If the water is being poured in S124 (NO in S124), the water level before bathing calculated from the unit water amount is updated (S127), and the process returns to S123.

If the water level is less than the reference water level + the added water level in S125 (NO in S125), the "bathing" signal OFF is transmitted to the remote controllers 30 and 32 (S128), and the process returns to S121. That is, since the water level may be lower than the reference water level when the bather leaves the bathtub 26 after taking a bath, the water level monitoring is terminated.

After the water level monitoring (S126), if the "during bathing" signal is OFF (YES in S129), the process proceeds to S130.

S130 to S136 are processing procedures when the "in bathing" signal is OFF, that is, when the patient is not in the bath. In S130, S131, and S132, the start of bathing is determined. A volume rise of a predetermined volume or more has been detected from the water level before a predetermined time (YES in S130), a water level rise above a predetermined rise level from the water level before bathing (YES in S131), and a predetermined LSB (Least significant) from the water level before bathing. If the water level rises above bit) (YES in S132), it is determined that the patient is in a bathing state and bathing has started, and the "bathing" signal ON is transmitted to the remote controls 30 and 32 (S133).

The water level before a predetermined time is set to, for example, 10 [seconds] before, and the predetermined volume is set to, for example, 10 [liters]. That is, in S130, the judgment is based on the volume, and unlike the rise in water level, it is not affected by the size of the bathtub 26. The water level and the predetermined volume before a predetermined time may be any water level and volume that can be judged to be a water level change due to the movement of the bather, for example, and are set based on a water level change of 60 [liters] or more per [minute]. ..

The predetermined rising water level is set to, for example, a water level corresponding to 16 [liters]. This change in water level corresponds to a change in water level in which a body weight of 15 [kg] is submerged in hot water. Is detected.

The predetermined LSB is set to, for example, 4LSB. This LSB represents a water level detection unit by the water level sensor 6. If such a water level is set, erroneous detection of the output of the water level sensor 6 due to the temperature characteristic is suppressed.

If the volume rise above the predetermined volume from the water level before the predetermined time is not detected in S130 (NO in S130), if the water level rises below the predetermined rise level from the water level before bathing in S131 (NO in S131), or in S132. If the water level rises below the predetermined LSB from the water level before bathing (NO in S132), it is determined whether the water level is stable (S134). If the water level is stable (YES in S134) and lower than the water level when bathing is detected (YES in S135), the water level before bathing is updated (S136) and the process returns to S123. If the water level is unstable (NO in S134), or if the water level is higher than the water level when bathing was detected (NO in S135), the process returns to S123.

After the water level monitoring (S126), if the "in bathing" signal is ON (NO in S129), the process proceeds to S137.

S137 to S144 are processing procedures when the “during bathing” signal is ON, that is, when the bathing state is in effect. In S137, S138, and S139, the end of bathing is determined. A volume drop of a predetermined volume or more has been detected from the water level before a predetermined time (YES in S137), a water level drop of a predetermined volume or more from the water level after bathing after the bather has taken a bath (YES in S138), and before bathing. If the difference from the water level is less than the predetermined amount of water (YES in S139), it is determined that the bathing state has been completed and the "bathing" signal OFF is transmitted to the remote controls 30 and 32 (S140).

The water level before a predetermined time is set to, for example, 10 [seconds] before, and the predetermined volume is set to, for example, 10 [liters]. S137 may be, for example, detection in the direction opposite to that of S130, that is, detection of volume increase in S130, while detection of volume decrease in S137.

The predetermined falling water level is set to, for example, a water level corresponding to 15 [liters]. For example, S138 may detect the water level in the opposite direction to S131, that is, S131 may detect a water level rise, while S138 may detect a water level drop, but the water level may be set to a value smaller than the predetermined rising water level of S131 to take a bath. Hysteresis is given to the detection.

The predetermined amount of water is set to, for example, 25 [liters].

If the volume drop of the predetermined volume or more is not detected from the water level before the predetermined time in S137 (NO in S137), or if the water level drops below the predetermined falling water level from the water level after bathing in S138 (NO in S138), the water level is stable. (S141). If the water level is stable (YES in S141) and higher than the water level when bathing is detected (YES in S142), the water level is updated after bathing (S143).

If the difference from the pre-bathing water level is greater than or equal to the predetermined amount in S139 (NO in S139) and the water level drops below the pre-bathing water level (YES in S144), or after the post-bathing water level is updated, the water level is below the pre-bathing water level. If it decreases to (YES in S144), it is determined that the patient is not in the bathing state and the bathing has been completed, and the "during bathing" signal OFF is transmitted to the remote controls 30 and 32 (S140). By including S144, the end of bathing can be detected even when the end of bathing cannot be detected in S137, S138, and S139, such as when the bather slowly moves out of the bathtub 26.

If the water level is unstable in S141 (NO in S141), if it is lower than the water level when bathing is detected in S142 (NO in S142), or if the water level exceeds the pre-bathing water level in S144 (S144). NO), return to S123.

According to this processing procedure, the accuracy of the determination of the start of bathing and the end of bathing is improved by combining a plurality of determinations. That is, the accuracy of the determination of the start and end of bathing is improved by updating the water level before bathing and the water level after bathing and detecting the water level using the water level before bathing, the water level after bathing, and the water level before a predetermined time.

<Set time lapse notification processing>

FIG. 30 shows an example of the processing procedure of the set time lapse notification processing. This processing procedure is an example of the setting time lapse notification processing of the bathing management program of the present invention. In this processing procedure, the notification signal is transmitted.

In this processing procedure, if the setting of the bathing notification timer is changed, that is, if the setting of the "timer setting" data 132 is changed (YES in S151), the set time is updated (S152), the setting time is changed to S153, and the set time is set. If the setting is not changed (NO in S151), the process proceeds to S153.

In this processing procedure, if the water level of the bathtub 26 is being monitored (YES in S153) and the "during bathing" signal is ON (YES in S154), the bathing timer -80 has elapsed the set time of the bathing notification timer. (S155). If the water level is not being monitored in S153 (NO in S153), or if the "bathing" signal is OFF in S154 (NO in S154), the bathing timer 80 and snooze timer 82 are returned to 0 (timer clear), and notification is given. The signal OFF is transmitted by 2 transfers, the initial transmission is not set (S159), and the process returns to S151.

If the set time has not elapsed in S155 (NO in S155), the process returns to S151, and S151 to S155 are repeated.

If the set time has elapsed (YES in S155) and the first notification signal has not been transmitted (YES in S156), the snooze timer 82 is returned to 0 (timer clear) (S157), and the notification signal ON is transmitted by 2 transfers. , The notification signal OFF is transmitted by 2 transfers (S158).

In S156, even if the first notification signal has been transmitted (NO in S156) and the snooze timer ≥ the snooze set time (NO in S160), S157 and S158 are performed. The snooze setting time is set to, for example, 5 [minutes]. By this process, after the set time of the bathing notification timer elapses, the notification signal is transmitted every snooze set time. That is, the snooze is performed after the set time of the bathing notification timer has elapsed.

If the snooze timer <snooze set time in S160 (YES in S160), the process returns to S151.

<Bath display processing>

FIG. 31 is an example of a bathing display processing procedure. This processing procedure is executed by the processor provided on the kitchen remote controller 32 side. This treatment procedure may be included in the bathing management program of the present invention.

In this processing procedure, if the "in bathing" signal acquired by the kitchen remote controller 32 is ON (YES in S171), the bathing display 160 is displayed (S172), and if the signal is OFF (NO in S171). The bathing display 160 is hidden (S173).

According to such a processing procedure, it is possible to control the display of the bathing display 160 based on the "bathing" signal, and it is possible to notify a person other than the bather that the bathing is in progress.

<Notification processing of the passage of bathing time>

FIG. 32 is an example of a processing procedure for notifying the passage of bathing time. This processing procedure is executed by the processor provided on the bathroom remote controller 30 side. This treatment procedure may be included in the bathing management program of the present invention.

In this processing procedure, if the "FC notification" signal (signal of the "FC notification" data 140) is changed from OFF to ON by the control unit 40 (YES in S181), the melody output timer provided in the bathroom remote controller 30 is set to 0. (Timer clear) (S182), melody sound is output, and bathing time is displayed (S183). If there is a switch operation of the operation unit 98 (YES in S184), the notification melody sound is stopped, the bathing time display is hidden, the melody output timer is returned to 0 (S185), and the process returns to S181.

If there is no switch operation in S184 (NO in S184), for example, the elapse of the notification set time is determined, and if the notification set time has elapsed (YES in S186), the process proceeds to S185. The notification set time is a set value of the output time of the melody sound and the display time of the bathing time, and is set to, for example, 30 [seconds].

If it is within the notification set time in S186 (NO in S186), it is determined whether the "bathing" signal is OFF, and if the signal is OFF (YES in S187), the process proceeds to S185.

If the "bathing" signal is ON in S187 (NO in S187), the process returns to S183 and repeats S183 to S187.

When the "FC notification" signal is OFF, ON, or changed from ON to OFF in S181 (NO in S181), this S181 is repeated.

According to such a processing procedure, it is possible to output a melody sound and display the bathing time when the bathing time has elapsed based on the "FC notification" signal. Further, the output of the melody sound and the display of the bathing time are stopped after the lapse of a predetermined time, but even before the lapse of the predetermined time, the bathing is stopped if the bather takes a bath, that is, if he / she gets out of the bathtub.

As described above, the bathing state in the bathtub 26 is displayed on the kitchen remote controller 32 installed outside the bathroom, and when bathing is detected, the counting of the bathing timer 80 is started and the time set by the user elapses. Then, the bathroom remote controller 32 utters a melody sound. The melody sound is uttered until a certain period of time elapses or a bather comes out of the bathtub 26. If the bather does not get out of the bathtub 26, a melody sound is uttered every 5 [minutes] after the lapse of the set time, and the bather is urged to get out of the bathtub. The utterance may be a guidance sound instead of the melody sound, or may be a combination of the melody sound and the guidance sound.

<Variation example of bathing detection>

In the above embodiment, it is determined whether or not the person is taking a bath based on the water level detection information detected by the water level sensor 6. However, for example, a bathing sound is acquired by a microphone mounted on the bathroom remote control 30, and the bathing sound information is used to take a bath. It may be determined whether or not it is. Further, the human body sensor 16 described above may be mounted on the bathroom remote controller 30 so as to determine whether or not the person is taking a bath based on the human body detection information. In this case, if a bathing notification function is added to the control unit installed in the bathroom remote controller 30, the process of the bathroom remote controller 30 can notify the elapse of the bathing time, and a "bathing" signal is output to the kitchen remote controller 32. can do.

<Variation example of bathing notification function setting>

In the above embodiment, the bathing notification function is set on the main menu screen 148, but the bathing notification function may be turned on or off by pressing and holding the key.

For example, when the bathing notification function is "OFF", if the down key for lowering the bathtub water level is pressed and held for 3 [seconds], a "function ON reception" sound is output and the notification function setting screen 168 shown in FIG. 33 is displayed. The bathtub mark 170 including the bath temperature setting may be blinked for 2 [seconds] in a cycle of 0.5 [seconds], and the "bathing notification on / off" signal "1" may be transmitted by 2 transfers to the heat source machine 28. For example, the blinking of the display is returned to the lighting display after blinking four times. Also, when the bathing notification function is "on", if the down key to lower the bath water level is pressed and held for 3 [seconds], the "function OFF reception" sound is output and the bathtub mark 170 is set to 1 in 0.5 [seconds] cycles. [Seconds] A blinking display may be made, and the "bathing notification on / off" signal "0" may be transferred and transmitted to the heat source machine 28 by two. For example, the blinking of the display is returned to the lighting display after blinking twice.

According to this modification, it is not necessary to switch to the main menu screen 148 or the bathing notification menu screen 150, and the setting operation becomes simple.

<Modification example of notification timer setting>

In the above embodiment, the notification timer is set on the bathing notification timer setting screen 156, but the timer may be set by pressing and holding the key.

For example, when the time setting key (not shown) and the volume key provided in the bathroom remote control 30 are pressed at the same time, a "function ON reception sound" (button sound) is output and displayed as shown in the bathing notification timer setting screen 172 shown in FIG. 34. A display 174 including a bathtub mark and a timer segment is displayed, and the current bathing notification timer setting time is blinked on the time display unit 176, and the guide sound "Enter with the up and down buttons." Is displayed twice. It is output and the bath notification timer change mode is set. In the timer change mode, all but the display "bath", the bathtub mark and the timer segment display 174 are turned off.

On the bathing notification timer setting screen 172 in the bathing notification timer change mode, the time for generating the long-time bathing warning is set. When the up and down keys 110, 112, and 114 are pressed, the timer setting is incremented by one step (for example, 5 [minutes]) along with the output of the operation sound each time the keys are pressed. If the up key is pressed while the timer setting has reached the maximum set time, the reception prohibition sound is output. If the lower key of the up / down key is pressed, the timer setting is reduced by, for example, 5 [minutes] along with the output of the operation sound each time the key is pressed. If the down key is pressed while the timer setting has reached 5 [minutes], the reception prohibition sound is output.

On the bathing notification timer setting screen 172, if the up key or the down key is pressed and held for 1 [second] or more, auto-repeat in units of 10 [minutes] is performed at intervals of, for example, 0.5 [seconds].

If the time setting key is pressed during the bathing notification timer change mode, the notification melody is output and, for example, the guide sound "Set." Is output twice, the time is switched to the lighting display, and the bathing notification timer is changed. Exit the mode.

On the bathing notification timer setting screen 172, press the return key 122 to output an operation sound and switch to the basic setting menu. At this time, the setting is not changed.

When the bath automatic key 102, the chasing key 104, the call key 106, the operation key 100, and the time setting key are operated during the bathing notification timer change mode, the bathing notification timer change mode is terminated.

When 30 [seconds] have elapsed without pressing the up / down keys 110, 112, 114, the guide sound "set" is output twice, for example, and the bathing notification timer change mode is terminated.

If there is a time change at the end of the bathing notification timer change mode, the changed "timer setting" data 132 is transferred and transmitted to the heat source machine 28.

According to this variant, there is no need to switch to the menu screen. Setting operation becomes easy.

<Transformation example of display during bathing>

In the above embodiment, the bathing display 160 shown in FIG. 23 is displayed, but for example, as in the bathing display screen 174 shown in FIG. 35A, the segment 178 in the lower half of the fifth digit of the time display unit 176 is set to 1 [second]. ] If the display is rotated clockwise as shown in B of FIG. 35 at intervals, the change in this display can attract the attention of persons other than the bather.

The features and modifications of the embodiments and examples described above are listed below.

(1) In the above embodiments and examples, the water heater and the remote control device are exemplified, but for example, an electronic device such as a smartphone, a tablet terminal, and a bathroom television may be used. In this case, if the bathing management program described above is mounted on these electronic devices, bathing can be monitored using the microphones, cameras, displays, and speakers of these electronic devices. Further, these electronic devices may be used as display means or notification means instead of the remote control device, and a water heater may be combined. In this case, the water heater and the electronic device are connected by a communication unit provided in the water heater and the electronic device. If the determination result of the state determination means or the bathing time determination means is output by the communication unit by wireless communication, the electronic device can output the determination result, the notification information or the alert. According to wireless communication, it is not necessary to connect each device by a signal line, and bathing information can be notified to a family member or an acquaintance living in another house.

(2) In the above embodiment, the communication interface 86 and the communication line 96 are used for the connection between the hot water supply / heating device 24 and the remote controllers 30 and 32, but the communication unit may be used for wireless communication. According to wireless communication, it is not necessary to connect each device by a signal line, and bathing information can be notified to a family member or an acquaintance living in another house.

(3) A plurality of set times may be set for the reference time or the set time of the bathing notification timer. If you set multiple set times, you can easily change the set time without raising or lowering the time. Further, a plurality of set times may be associated with the time information so that different set times can be set for the morning, night time, and other time zones. According to such an example, the troublesomeness of changing the set time according to the bathing time is reduced.

(4) In the above embodiment, the kitchen remote controller 32 indicates that the person is taking a bath, and the bathroom remote controller 30 notifies the bathroom that the bathing time has elapsed. For example, the kitchen remote controller 32 is used. You may notify outside the bathroom that the bathing time has passed. It can be an opportunity for a person other than the bather to recognize the passage of the bathing time and confirm the bathing of the bather. In addition, if the bather does not get out of the bathtub even though the passage of bathing time is notified to the bathroom, it can be an opportunity to check the bathroom. When the elapse of the bathing time is notified to the bathroom and the outside of the bathroom, these notifications may be made at the same time, or the notification may be made to the outside of the bathroom after a predetermined time from the notification in the bathroom. By delaying the timing of the notification outside the bathroom, it is possible to avoid giving the notification outside the bathroom when the bather leaves the bathtub in response to the notification. In other words, the degree of freedom of notification is increased.

As described above, embodiments and the like of the present invention have been described, but the present invention is not limited to the above description, and the gist of the invention described in the claims or disclosed in the specification. It goes without saying that various modifications and changes can be made by those skilled in the art based on the above, and it goes without saying that such modifications and changes are included in the scope of the present invention.
