Description

The present invention relates to bathing management technology used for managing bathing time and the like.

  Accidents during bathing occur during single bathing without the attendant being accompanied even by a healthy person. For example, fainting or dozing may cause the bather to be submerged, and the bather may die without realizing the inundation.

  It is known to watch the body movement sound of the bather outside the bathtub by using a microphone mounted on a remote control in the bathroom (for example, Patent Document 1).

Also, by combining the detection of sound in the bathroom by the microphone and the detection of entrance into the bathroom by the infrared distance measuring sensor, the abnormal operation of the detected person in the detection space is determined, and from the detection space of the detected person It is known to instruct the withdrawal of (see, for example, Patent Document 2).

<Timer function>

  FIG. 7 shows a plurality of timer functions implemented by the processor 48-1 of the control unit 8. In this embodiment, the processor 48-1 measures the bath staying time TR, the bathing time TB, the accumulated bathing time TBm, the in-tub silence time TS, the outside-tub staying time TM, and the out-of-bath measurement time TO. In order to measure these times, the processor 48-1 implements first to sixth timer functions 72-1, 72-2,... 72-6 as a plurality of timer functions.

  The bath stay time TR is the time for the bather to stay in the bath 14 and is measured by the timer function 72-1. A threshold value TRref is set to the bathroom staying time TR, which is, for example, 60 [minutes].

  The bathing time TB is a time for the bather to enter the bathtub 20 and continue bathing, and is measured by the timer function 72-2. A threshold value TBref is set to the bathing time TB, which is, for example, 30 minutes. Further, the number of times of bathing BN is the number of times of bathing repeated in units of the bathing time TB within the bath stay time TR. The threshold BNref may be set also for this number of times.

  The accumulated bathing time TBm is a time obtained by integrating the bathing time TB, and can be obtained by integrating the bathing time TB by the timer function 72-3. A threshold TBmref is set to the accumulated bathing time TBm, which is, for example, 50 (minutes).

  The in-tub silent time TS is a time when a bather is silenced in the bathtub 20 while taking a bath, and is measured by the timer function 72-4. A threshold TSref is set to the in-tub silent period TS, and is, for example, 20 minutes.

  The bath outside staying time TM is a time for a bather staying in the bathroom 14 to stay outside the bathtub 14, for example, at the washing place 22, and is measured by the timer function 72-5. A threshold TMref is set to this outside-tub staying time TM, for example, 10 [minutes].

  The measurement time TO outside the bathroom is a time to determine that the bather has left the bathroom 14 and is measured by the timer function 72-6. A threshold value TOref is set to the outside-bath measurement time TO, which is, for example, 5 minutes.

<Monitoring the sound and bath level>

  FIG. 8 shows the monitoring state of sound and bathtub water level.

  During bathing, as shown in A of FIG. 8, the sound in the bathroom 14 is detected in the microphone 4 and converted to a sound signal. The amplitude threshold ± S is set for the sound signal exhibiting this continuous amplitude level change. The sound signal is subjected to window comparator processing using the amplitude threshold ± S as a comparison level to determine the presence or absence of sound. That is, among the sound signals, level sounds below the lower limit level -S exceeding the range of the amplitude threshold and above the upper limit level + S are determined as sounds. Thus, the sound determination output shown in B of FIG. 8 is obtained. In this sound determination output, H is a sound section and L represents a sound non-section.

  The water level sensor 6 detects the bath water level or its change as shown in I of FIG. 8 and converts it to a water level signal. That is, it can be estimated that the bather has sunk in the bath 20 and the bath water level has risen by the body volume. A threshold Lref is set for the water level signal exhibiting this continuous water level change. If the water level signal is compared with the threshold value Lref, it is possible to determine the presence or absence of bathing depending on whether the threshold value Lref is exceeded. Thereby, the inside / outside determination output of the bathtub shown to J of FIG. 8 is obtained. In the inside and outside determination output of this bathtub, H is a bathing area and L represents a non-bathing area.

As shown in FIG. 8 for such a sound judgment output and the inner and outer sections of the bathtub,
t0: start point of the H level of the sound determination output,
t1: When bathing starts,
t2: Transition time point of the sound determination output from H level to L level,
t3: Transition point of sound determination output from L level to H level,
t4: At the end of bathing,
t5: The next bathing start time,
t6: Transition point of the sound determination output from H level to L level,
t7: Transition time point of the sound determination output from L level to H level,
t8: Transition point of the sound determination output from H level to L level,
t9: Transition point of sound determination output from L level to H level,
t10: At the end of bathing,
t11: The transition time point of the sound determination output from H level to L level,
t12: Each time point at which the outside of the bathroom measurement time TO ends is determined.

  Thereby, as shown to B of FIG. 8, H level area B1, B2, B3, B4 of a sound determination output is obtained. Moreover, if the combination with the presence or absence of a bath can be performed, the in-bath situation of the bather who stays in a bath can be grasped in more detail.

As shown in C of FIG. 8, the bathroom staying time TR is a section from time point t1 to t12. The start time of the bath stay time TR may be from the start time t0 of the H level of the sound determination output, but in this example, the first bath start time is t1 taking into consideration the case of not entering the room and not taking a bath. In this case, the bather performs bathing twice, and as shown to D of Drawing 8, bathing time TB1 is a section of time t1-t4, and bathing time TB2 is time t5-t10. Therefore, the integrated bathing time TBm is bathing time TB1 + bathing time TB2, and as shown in E of FIG. 8, it is an integrated time of time t1 to t10.

  In these bathing times TB1 and TB2, several bath silence periods TS1, TS2 and TS3 exist in which the sound signal level is lower than the amplitude threshold for the bather. As shown in FIG. 8F, the dead time TS1 is a time point t2 to t3, the dead time TS2 is a time point t6 to t7, and the dead time TS3 is a time width from a time point t8 to t9.

  Also, the bather goes out of the bath twice, and there are time TM1 and TM2 for staying outside the bath. As shown in G of FIG. 8, the bathtub external staying time TM1 is time t4 to t5, and the bathtub external staying time TM2 is t10 to t12.

  And as shown to H of FIG. 8, the measurement time TO outside a bathroom is measured at the time t11-t12.

<Processing procedure>

  FIG. 9 shows a processing procedure of time measurement. This processing procedure is an example of the bathing management method of the present invention, and is an example of a processing procedure realized by causing a computer to execute the bathing management program of the present invention. In this processing procedure, timer measurement of each timer function 76-1 to 76-6 is performed in time measurement (S201). This timer reset may be performed when the power is turned on, or when the bather's bathing is completed.

  The time measurement is started when the bather starts bathing in the bathroom 14 (S202). Each measured time is compared with a threshold to determine whether it is normal or abnormal during measurement (S203).

  The judgment result and the information on time lapse during measurement are presented (S204). This information presentation may be displayed on the display units 66-1 and 66-2.

  Then, it is determined that the bather leaves the bathroom 14 (S205), and the bathing management processing procedure is ended.

  FIG. 10 shows an example of a detailed process procedure of bathing management. This processing procedure is a procedure that embodies the processing procedure shown in FIG.

  In this processing procedure, monitoring of the bathtub water level and the bathroom sound is continued (S301). It is determined whether the bath water has risen (S302), and if the bath water level has not risen, the reference value is reviewed (S303), and the process returns to S301.

  If the bath tub level rises (YES in S302), the timer function 72-1 starts time measurement (S304), the timer function 72-2 starts time measurement (S305), and the timer function 72-3 measures time Is started (S306).

  It is determined whether there is a bathroom sound (S307). If there is no bathroom sound (NO of S307), time measurement of the timer function 72-4 is started (S308).

  The measurement time TS of the timer function 72-4 is compared with the threshold value TSref to determine whether TS ≧ TSref (S309). If TS ≧ TSref (YES in S309), time-over processing is executed (S310). This time over process includes information presentation such as displaying that time is over and prompting a bather to warn, and so on. If TS <TSref (NO in S309), S310 is skipped.

  It is determined whether there is a bathroom sound (S311). If there is no bathroom sound (NO in S311), the measurement time TR of the timer function 72-1 is compared with the threshold value TRref to determine whether TR ≧ TRref (S312). If TR ≧ TRref (YES in S312), time-over processing is executed (S313). If TR <TRref (NO in S312), S313 is skipped.

  The measurement time TB of the timer function 72-2 is compared with the threshold TBref to determine whether TBTBTBref (S314). If TB ≧ TBref (YES in S314), time-over processing is executed (S315). If TB <TBref (NO in S314), S315 is skipped.

  The measurement time TBm of the timer function 72-3 is compared with the threshold TBmref to determine whether TBmmTBmref (S316). If TBm ≧ TBmref (YES in S316), time-over processing is executed (S317). If TBm <TBmref (NO in S315), S317 is skipped.

  Here, the lowering of the water level in the bathtub is determined (S318). If the bath water level has not dropped (NO in S318), the process returns to S309 and continues the processing of S309 to S318 until the bath water level drops.

  If there is a bathroom sound in S307 (YES in S307), the time measurement of the timer function 72-4 is stopped (S319). Again, the presence or absence of a bathroom sound is determined (S320). If there is no bathroom sound (NO in S320), the process proceeds to S308.

  If there is a bathroom sound (YES in S320), the measurement time TR of the timer function 72-1 is compared with the threshold value TRref to determine whether TR ≧ TRref (S321). If TR ≧ TRref (YES in S321), time-over processing is executed (S322). If TR <TRref (NO in S321), S322 is skipped.

  The measurement time TB of the timer function 72-2 is compared with the threshold TBref to determine whether TBTBTBref (S323). If TB ≧ TBref (YES in S323), time-over processing is executed (S324). If TB <TBref (NO in S323), S324 is skipped.

  The measurement time TBm of the timer function 72-3 is compared with the threshold value TBmref to determine whether TB ≧ TBmref (S325). If TB ≧ TBmref (YES in S325), time-over processing is executed (S326). If TB <TBmref (NO in S325), S326 is skipped.

  Here, it is determined whether the bath water level has dropped (S327). If the bath water level has not dropped (NO in S327), the process returns to S320, and continues the processing of S320 to S327 until the bath water level drops.

  If the water level in the bathtub drops (YES at S318 or S327), the time measurement of the timer function 72-2 is stopped (S328), the time measurement of the timer function 72-3 is stopped (S329), and the timer function 72- The time measurement of 4 is stopped (S330), and the time measurement of the timer function 72-5 is started (S331).

  And a bathroom sound is judged (S332). If there is no bathroom sound (NO of S322), the time measurement of the timer function 72-6 is started (S333). The measurement time TO is compared with the threshold TOref to determine whether TO ≧ TOref (S334). If TO ≧ TOref (NO at S334), a bathroom sound is determined (S335). If there is a bathroom sound (YES in S335), the process proceeds to S341.

  If there is no bathroom sound (NO in S335), the measurement time TR of the timer function 72-1 is compared with the threshold value TRref to determine whether TR ≧ TRref (S336). If TR ≧ TRref (YES in S336), time-over processing is executed (S337). If TR <TRref (NO in S336), S337 is skipped.

  The measurement time TM of the timer function 72-5 is compared with the threshold value TMref to determine whether TM ≧ TMref (S338). If TM ≧ TMref (YES in S338), time-over processing is executed (S339). If TM <TMref (NO at S338), S339 is skipped. Here, the rise of the bathtub water level is determined (S340). If the bathtub water level has not risen (NO of S340), it will return to S334 and will continue processing of S334-S340 until a bathtub water level rises.

  In S332, if there is a bathroom sound (YES in S332), the time measurement of the timer function 72-6 is stopped (S341), and the bathroom sound is determined (S342). If there is a bathroom sound (YES in S342), the measurement time TR of the timer function 72-1 is compared with the threshold value TRref to determine whether TR ≧ TRref (S343). If TR ≧ TRref (YES in S343), time-over processing is executed (S344). If TR <TRref (NO at S343), S344 is skipped.

  The measurement time TM of the timer function 72-5 is compared with the threshold TMref to determine whether TM ≧ TMref (S345). If TM ≧ TMref (YES in S345), time-over processing is executed (S346). If TM <TMref (NO at S345), S346 is skipped.

  Then, it is determined that the bath water level is rising (S347). If the bath water level has not risen (NO in S347), the process returns to S342, and the processes in S342 to S347 are executed.

  If the bathtub water level has risen (YES of S340 or YES of S347), time measurement of the timer function 72-2 will be started (S348). The time measurement of the timer function 72-3 is continued (S349), and the process returns to S307.

  If TO TO TOref at S334 (YES at S334), measurement of the measurement times TR, TB, TBm, TS, TM, and TO of all timer functions 72-1 to 72-6 is stopped (S350) ), The room exit process is executed (S351), and the process returns to S302.

<Effect of the embodiment>

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

  (1) The bath water level or its change, detection of the voice in the bathroom, and its duration time are measured, so it is possible to enhance the safety of the bather who is open from time management and sense of time when bathing.

  (2) The state of the bather can be determined by the detection of the bathtub water level by the water level sensor 6 and the sound detection by the microphone 4 mounted on the bathroom remote control device 28.

  (3) At the detected water level by the water level sensor 6, at least the situation inside and outside the bather's bathtub is detected, and it is determined whether or not the bather is in a bathing state by this detected water level.

  (4) As the microphone 4, for example, an existing microphone provided in the bathroom remote control device 28 installed in a portion which is easily operated by a bather in the bathtub can be used. If such a microphone 4 is used, there is no need to install a separate microphone, and the breathing sound of the bather, voices related to the bather themselves such as nasal singing, operation sounds and water sounds of the hot water tap and shower plug of the bather, etc. It can be detected and the situation of the bather can be determined. Among the components of the sound from the microphone 4, an amplitude component may be detected.

  (5) By detecting the water level detected by the water level sensor 6, the sound detected by the microphone 4, and the durations of these, it is possible to make a plurality of situation determinations such as a bath stay time and a doze state in the bath with higher accuracy.

  (6) As an example, the start of bathing may be triggered by a change in the water level detected by the water level sensor 6.

  (7) As an example, the end of the bathing may be determined from a silent state for a predetermined period of time after detection of the bath tub level by the water level sensor 6. If there is a detection sound even when coming out of the bathtub 20, it may be determined that the bathing state is continuing.

  (8) If the detection of the bathtub water level by the water level sensor 6 is used in combination with the silent state for a predetermined time to be continued, it can be accurately determined that the bather is in a nap state.

  (9) In the above embodiment, a plurality of time measurements can be made as an example. This time measurement is firstly bathing time from the start of bathing to leaving the bathroom, secondly bathing time for each entering bath (for example, duration time detected by water level sensor 6 above the predetermined level) ), Thirdly, accumulated bathing time accumulated multiple bathing times, fourthly, silence time in bath (sleep time), fifth, staying time outside bath outside in bath in bath included.

  (10) A plurality of timer functions used for each time measurement are provided, and it is sufficient to select the time setting and the presence / absence of use.

  (11) The threshold value may be reconsidered as a reference value for detecting the water level and voice, such as the water level value before bathing and the volume of the unmanned state, for example, stored in the memory unit 50-1, and learning and updating as needed. This enables sophisticated bathing management.

  (12) In this bathing management apparatus 2, for example, a water level detection means for detecting the water level in the bath, a sound detection means for detecting a sound in the bathroom, first detection information detected by the water level detection means, and a sound detection means And the measuring means for measuring the state of the bather by the second detection information detected by

  (13) A sensor function such as a water level sensor 6 or a microphone 4 provided in a general heat source such as a water heater can be used, and the situation of each bather in the bathroom can be grasped by the information obtained by this sensor function The time can be measured or accumulated, and the result can be used to notify the bather of a necessary warning or the like, such as awakening from a situation or a doze state, using an information presentation function such as a display unit or a speaker. In addition to human detection using the water level sensor 6 and the microphone 4, an alert function of long-time bathing and dozing can be prevented.

 (14) Since voice detection and water level detection generated by a bather are performed in combination with bathing management, the existing microphone 4 and water level sensor 6 can be used, and detection of a bather, stay place, and stay time can be measured with high accuracy. , Can enhance the safety of bathers.

  (15) The use of a special sensor or the use of a unique information monitor for grasping the situation of bathers leads to an increase in cost, which causes problems such as false detection, etc. It can be avoided in the embodiment.

  (16) The detection information obtained from the microphone 4 and the water level sensor 6 provided to the existing heat source equipment can be used to grasp the situation of the bather, and the accumulation of the detection information and the history thereof can be stored. The determination result can be used to increase the safety of the bather, such as alerting the bather as an alert or notifying the administrator.

  (17) Management that manages information for each bather by storing information stored in one or more of the memory units 50-1, 50-2, and 50-3 in association with information obtained during bathing with identification information of the bather It may be in the form.

Other Embodiments

  FIG. 14 shows state transition of the bathing management device according to another embodiment. In this embodiment, the non-bathing state 102, the bathroom entering state 104, the bathtub bathing state 106, the drowsy alert notification state 108, and the room entering / bathing detection prohibited state 110 are set as bathing management states.

  A transition to the bathroom entering state 104 is made from the no-bathing state 102 by sound detection (S401). In the bathroom entry state 104, entry is displayed on the bathroom remote control device 28 and the kitchen remote control device 30 (S402). If, for example, T = 5 [minutes] elapses as a predetermined time T1 continuously from the bathroom entering state 104 as a state in which no sound is detected (S403), the bathroom entering state 104 is changed to the no bathing state 102. At this time, the room entry display of the bathroom remote control device 28 and the kitchen remote control device 30 is canceled.

  If the bath water level rises from the bathroom entering state 104 (S 404), the state transitions to the bathtub bathing state 106. In the bathtub bathing state 106, the bathroom remote control device 28 and the kitchen remote control device 30 indicate that the user is taking a bath (S405). If the bathtub water level is lowered from the bathtub bathing state 106 (S406), the state is shifted to the bathroom bathing state 104. At this time, the bathing display of the bathroom remote control device 28 and the kitchen remote control device 30 is canceled.

  Even if there is no bathing state 102, if a rise in the bath water level is detected (S407), the bathroom entering state 104 is skipped, and a transition to the bathtub bathing state 106 is made.

  If, for example, T2 = 10 [minutes] elapses as the predetermined time T2 from the bathtub bathing state 106 as the state without sound detection, the process transitions to the drowsy alert state 108. When transitioning to the drowsy alert notification state 108, the drowsy alert is notified at least to the bather. For example, when T3 = 30 [seconds] elapses as the predetermined time T3 from the drowsy alert notification state 108 (S409), the drowsy alert notification state 108 transitions to the bathtub bathing state 106. If the bather performs the notification stop operation in the drowsy alert notification state 108 (S410), the drowsy alert notification state is returned to the bathtub bathing state 106.

  In the drowsy alert notification state 108, if the bathtub water level drops (S411), the bathtub bathing state 106 is skipped and the process returns to the bathroom entering state 104. That is, if the bather comes out of the bathtub 20 without performing the notification stop operation, it can be determined that the drowsy state has been eliminated.

  In the bathroom entering state 104, the bathtub bathing state 106, or the drowsy alert notifying state 108, if the room remote control 28 is operated to perform the room entry / bathing detection release operation (S412, S413, S414), the room entry / bathing detection prohibited state 110 is made. Transition.

  Even if such room entry / bathing detection release operation is performed, if the room entry / bathing detection start operation is performed from the room entry / bathing detection prohibition state 110 (S 415), the state transitions to the bathroom entry state 104.

  If, for example, T4 = 1 [hour] has passed as the predetermined time T4 from the transition time of the room entering / bathing detection prohibited state 110 (S416), the room entering / bathing detection prohibited state 110 is transited to the no bathing state 102.

  FIG. 15 shows a procedure of bathing management according to another embodiment. This processing procedure is an example of the bathing management method of the present invention, or an example of the bathing management method realized by executing the bathing management program.

  In this processing procedure, it is determined whether there is a bathroom sound (S501). If there is a bathroom sound (YES in S501), it is determined that the bath water level has risen (S502). If there is no bathroom sound (NO in S501), it is determined whether or not T1 = 5 minutes, for example, as the predetermined time T1 from the detection of the bathroom sound (S503). If it is not within T = 5 [minutes] (NO in S503), the process returns to S501. If T1 = 5 minutes or less (YES in S503), the process in S502 is performed.

  If the bath tub level rises (YES in S502), it is determined that there is a bath (S504), and the presence of a bath is displayed (S505). If the bath water level does not rise (NO in S502), the process returns to S501.

  In this case, the time measurement of the timer function 72-4 is started along with the display start with bathing (S506). The timer function 72-4 measures the time for which the sleep state continues.

  The bathroom sound is determined (S507). If there is no bathroom sound (NO in S507), the fluctuation of the bath water level is determined (S508). If there is no change in the bathtub water level (YES in S508), if the measurement time T2 of the timer function 72-4 is, for example, T2 = 10 [minutes] (YES in S509), a doze alarm sound is generated (S510). It is determined whether, for example, T3 = 30 [seconds] has passed as the predetermined time T3 from the start of the drowsy prevention warning sound. If T3 = 30 [seconds] has passed (YES in S511), the drowsy prevention warning sound is stopped (S512). Even if T3 = 30 [seconds] has not elapsed (NO in S511), if there is a stop operation of the doze prevention warning sound (YES in S513), the doze prevention warning sound is stopped (S512). If there is no stop operation of the drowsy prevention warning sound (NO in S513), the process returns to S510, and the generation of the drowsy prevention warning sound is continued.

  After stopping the drowsiness prevention warning sound, the time measurement of the timer function 72-4 is restarted, and the measurement time is re-measured (S514), and the process returns to S507.

  If there is a bathroom sound at S507 (YES at S507), or if there is a fluctuation in the water level at the bathtub (NO at S508), the time measurement of the timer function 72-4 is restarted and the measurement time is remeasured (S515), It is determined whether the water level in the bathtub is lowered (S516). If the water level in the bathtub does not decrease (NO in S516), the process returns to S507.

  If the water level in the bathtub is lowered (YES in S516), it is determined that the water level in the bathtub is increased (S517). If there is a rise in the water level in the bathtub (YES in S517), the process returns to S506, and the processing from S506 is performed.

  If there is no rise in the water level in the bathtub (NO in S517), it is determined whether the bathroom noise absence state is a predetermined time T1, for example, T1 = 5 minutes or more (S518). If the bathroom noise-free state has not continued for T = 5 minutes or more (NO in S518), the process returns to S517.

  If bathing is started while it is determined whether or not the bathroom sound non-presence state is a predetermined time T1 or more (S518), that is, if there is a rise in the water level in the bathtub (YES in S517), the process returns to S506 and executes the processes in S506 and thereafter.

  If the bathroom noise-free state has not continued for T = 5 minutes or more (NO in S518), the process returns to S517. If the bathroom noise non-existence state continues for T = 5 [minutes] or more (YES in S518), it is determined that there is no bathing state (S519), the bathing presence display is canceled (S520), and this process ends. Do.

<Effects of Other Embodiments>

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

  (4) In addition to the bathing detection by the water level sensor 6, since the bathing state can be complemented by the voice detection by the microphone 4, compared to the conventional bathing management in which the bathing state was grasped only by the water level rise, there is no sufficient water level rise Even in this case, it is possible to grasp the bathing state, and it is possible to cope with the situation. For example, in the case of a half body bath or in the case of a child, the bath water level rise level is small, and it may not be possible to distinguish the bather from inside or outside the tub by only the tub water level. You can know exactly where you are staying and whether you are in a bath, whether the bather is a child or is out of the bathtub and is in the washroom. It is possible to control the notification function for bathers and managers and their variations based on the grasp of the bathing situation.

  (5) In addition to the bathing detection by the water level sensor 6, since the bathing state can be complemented by the voice detection by the microphone 4, even if the change in the bath water level is small, the bathing person grasps an abnormality such as a nap or fainting state Yes, it is possible to take prompt action.

The bathing management apparatus according to any one of claims 1 to 3, further comprising: The said 1st sensor is a microphone installed in the bathroom remote control device, The said 2nd sensor is a water level sensor which detects a bathtub water level, The claim any one of the Claims 1 thru | or 4 characterized by the above-mentioned. The bathing management device as described in. A bathing management program to be executed by a computer mounted on an electronic device installed in or outside a bathroom, comprising:
Capturing a first detection signal from a first sensor that detects sound or vibration;
Taking in a second detection signal representing the detected water level from a second sensor that detects a water level or a change in water level in the bathtub;
Using the first detection signal and the second detection signal, measure the bathing person's bathing time from entry to exit,
Measuring a bathing time representing a continuing bathing state by the second detection signal within the bathing time;
This first detection signal within this bathing time measures a silence time representing a continuing silent state, and calculates an integrated bathing time for integrating the bathing time, outside the bathtub staying outside the bathtub within the bathing time Measure the stay time,
When increasing the bathtub water level is detected by the pre-Symbol second detection signal, the bath residence time, the bath time, to start the measurement of the integrated bathing time and the silence period, the first detection signal is outputted If the silence time does not exceed the predetermined time, whether the bathing time, the bathing time, or the accumulated bathing time exceeds the threshold set for each, or the bath water level according to the second detection signal If the bathing time, the bathing time, or the accumulated bathing time exceeds any of the thresholds, it is determined that the bather is abnormal, and the bath water level is decreased. Stops the measurement of the bathing time, the accumulated bathing time and the silence time to start the measurement of the bathing time outside the bath, and the bather's abnormality when the bathing time or the bathing time outside the bath exceeds a threshold determine the To,
