Description

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

  Accidents during bathing occur at the time of a single bath that is not accompanied by an administrator even if it is a healthy person. For example, fainting or falling asleep may cause the bather to submerge, and the bather may not be aware of the submergence and may be drowned.

  There is known a technique for watching a body motion sound of a bather outside a bathtub by using a microphone mounted on a remote controller in the bathroom (for example, Patent Document 1).

In addition, by using both sound detection in the bathroom with a microphone and detection of entry into the bathroom with an infrared distance sensor, the abnormal operation of the detected person in the detection space is determined, and the detection space of the detected person is determined. It is known to instruct to leave (for example, Patent Document 2).

  By the way, the remote control device in the bathroom is equipped with a microphone, and the microphone can pick up sound. According to this microphone, the body movement of the bather can be detected. However, sounds and vibrations other than body movements enter the microphone, and due to these noises, the bather's condition may not be accurately grasped.

  If an infrared distance measuring sensor is used, it is possible to know whether or not the bather stays in the detection space by the heat ray emitted by the bather. However, if the bather has already stayed in the bathroom for bathing, there is no need to confirm it. In the distance measurement by the infrared distance measuring sensor, it is difficult to determine a silence situation such as a bather's sleep, and if the determination is complicated, a delay in ensuring safety will be a problem.

In this embodiment, the processor 48-1 measures a bathroom stay time TR, a bath time TB, an accumulated bath time TBm, a bath silence time TS, a bath stay time TM, and a bath outside 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 bathroom stay time TR is a time during which the bather stays in the bathroom 14 and is measured by the timer function 72-1. A threshold value TRref is set for the bathroom staying time TR, 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. For this bathing time TB, a threshold value TBref is set, for example, 30 [minutes]. The number of baths BN is the number of baths repeated in units of the bath time TB within the bathroom stay time TR. The threshold value BNref may be set for this number of times.

  The accumulated bathing time TBm is a time obtained by accumulating the bathing time TB, and is obtained by accumulating the bathing time TB by the timer function 72-3. A threshold value TBmref is set as the integrated bathing time TBm, and is 50 [minutes], for example.

  The bath silence time TS is a time during which the bather is silent in the bath 20 during bathing, and is measured by the timer function 72-4. A threshold value TSref is set as the silence time TS in the bathtub, and is 20 [minutes], for example.

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

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

<Sound and bathtub water level monitoring>

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

  When bathing, the microphone 4 detects the sound in the bathroom 14 and converts it into a sound signal, as shown in FIG. 8A. An amplitude threshold value ± S is set for the sound signal exhibiting the continuous amplitude level change. The sound signal is subjected to window comparator processing with an amplitude threshold value ± S as a comparison level to determine the presence or absence of sound. In other words, among the sound signals, level sounds that are lower than the lower limit level −S and exceed the upper limit level + S exceeding the amplitude threshold range are determined as sounds. Thereby, the sound determination output shown in B of FIG. 8 is obtained. In this sound determination output, H represents a sound section and L represents a soundless section.

  As shown in I of FIG. 8, the water level sensor 6 detects the bath water level or its change and converts it into a water level signal. That is, it can be estimated that the rise in the water level is caused by the bather sinking his / her body in the bathtub 20 and the bathtub water level rising due to the body volume. A threshold Lref is set for the water level signal exhibiting this continuous water level change. If this water level signal is compared with the threshold value Lref, the presence or absence of bathing can be determined based on whether or not the threshold value Lref is exceeded. Thereby, the inside / outside determination output of the bathtub shown in J of FIG. 8 is obtained. In the inside / outside determination output of this bathtub, H is a bathing section and L represents a non-bathing section.

About such a sound determination output, the inside and outside section of the bathtub, as shown in FIG.
t0: start point of sound determination output H level,
t1: time to start bathing
t2: the transition point from the H level to the L level of the sound determination output,
t3: time point when the sound determination output shifts from L level to H level,
t4: at the end of bathing,
t5: next bath start time,
t6: time point when the sound determination output shifts from H level to L level,
t7: time point when the sound determination output shifts from L level to H level,
t8: When the sound determination output transitions from the H level to the L level,
t9: time point when the sound determination output shifts from L level to H level,
t10: at the end of bathing,
t11: time point when the sound determination output shifts from the H level to the L level,
t12: Each time point at the end of the measurement time TO outside the bathroom is determined.

  As a result, as shown in FIG. 8B, H level sections B1, B2, B3, and B4 of the sound determination output are obtained. Moreover, if the combination with the presence or absence of bathing can be performed, the situation in the bathroom of the bather who stays in the bathroom can be grasped in detail.

  As shown in C of FIG. 8, the bathroom staying time TR is a section from time t1 to t12. The bathroom stay time TR may be started from the start time t0 of the H level of the sound determination output. However, in this example, the first bathing start time is set to t1 in consideration of the case where the user does not enter the room and take a bath. In this case, the bather has bathed twice, and as shown in FIG. 8D, the bathing time TB1 is a section from time t1 to t4, and the bathing time TB2 is a section from time t5 to t10. Accordingly, the accumulated bathing time TBm is the bathing time TB1 + the bathing time TB2, and as shown in E of FIG.

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

  Moreover, the bather goes out of the bathtub twice and stays outside the bathtub TM1 and TM2. As shown in G of FIG. 8, the staying time TM1 outside the bathtub is a time point t4 to t5, and the staying time TM2 outside the bathtub is t10 to t12.

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

<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, the timer reset 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 completes bathing.

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

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

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

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

  The presence or absence of a bathroom sound is determined (S311). If there is no bathroom sound (NO in S311), the measurement time TR of the timer function 72-1 and the threshold value TRref are compared to determine whether TR ≧ TRref (S312). If TR ≧ TRref (YES in S312), a time over process 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 value TBref, and it is determined whether TB ≧ TBref (S314). If TB ≧ TBref (YES in S314), the time over process 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 value TBmref, and it is determined whether TBm ≧ TBmref is satisfied (S316). If TBm ≧ TBmref (YES in S316), the time over process is executed (S317). If TBm <TBmref (NO in S315), S317 is skipped.

  Here, the fall of the bathtub water level is determined (S318). If the bathtub water level has not fallen (NO of S318), it returns to S309 and continues the process of S309-S318 until the bathtub water level falls.

  If there is a bathroom sound in S307 (YES in S307), the time measurement of the timer function 72-4 is stopped (S319). The presence / absence of bathroom sound is determined again (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 and the threshold value TRref are compared to determine whether TR ≧ TRref (S321). If TR ≧ TRref (YES in S321), the time over process is executed (S322). If TR <TRref (NO in S321), S322 is skipped.

  The measurement time TB of the timer function 72-2 and the threshold value TBref are compared to determine whether TB ≧ TBref (S323). If TB ≧ TBref (YES in S323), a time over process 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, and it is determined whether TB ≧ TBmref is satisfied (S325). If TB ≧ TBmref (YES in S325), a time over process is executed (S326). If TB <TBmref (NO in S325), S326 is skipped.

  Here, the fall of the bathtub water level is determined (S327). If the bathtub water level has not fallen (NO of S327), it returns to S320 and continues the process of S320-S327 until the bathtub water level falls.

  If the bath water level falls (YES in 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- 4 is stopped (S330), and the time measurement of the timer function 72-5 is started (S331).

  Then, the bathroom sound is determined (S332). If there is no bathroom sound (NO in S322), the time measurement of the timer function 72-6 is started (S333). The measurement time TO is compared with the threshold value TOref, and it is determined whether TO ≧ TOref (S334). If TO ≧ TOref is not satisfied (NO in S334), the 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), a time over process 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), the time over process is executed (S339). If TM <TMref (NO in S338), S339 is skipped. Here, a rise in the bathtub water level is determined (S340). If the bathtub water level has not risen (NO in S340), the process returns to S334, and the processes in S334 to S340 are continued until the bathtub water level rises.

  If there is a bathroom sound in S332 (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, and it is determined whether TR ≧ TRref (S343).

<Effect of Example>

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

  (1) Since the bath water level or its change, the detection of sound in the bathroom, and the duration of the bath are measured, the safety of bathers who are free from time management and time sense during bathing can be improved.

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

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

  (4) As the microphone 4, for example, an existing microphone in the bathroom remote control device 28 installed at a place where a bather in the bathtub can easily operate can be used. If such a microphone 4 is used, there is no need to install a separate microphone, and the sound of the bather itself, such as the breathing sound of the bather, nose singing, and the operation sound and water sound of the bather's hot water tap and shower tap, etc. It can detect and determine the situation of bathers. Of the sound components from the microphone 4, an amplitude component may be detected.

  (5) By detecting the detected water level of the water level sensor 6, the detection sound of the microphone 4, and the duration of these, it is possible to make a plurality of situation determinations such as staying time in the bathroom and sleeping state in the bathtub 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 bathing may be determined from the silent state for a predetermined period of time after the water level sensor 6 detects the bath water level. What is necessary is just to determine with the bathing state continuing if there is a detection sound even if it comes out of the bathtub 20.

  (8) If the detection of the bath water level by the water level sensor 6 and the continuous silent state for a predetermined time are used in combination, it is possible to accurately determine that the bather is in a dozing state.

  (9) In the above embodiment, a plurality of time measurements can be performed as an example. In this time measurement, firstly, the staying time in the bathroom from the start of bathing until leaving the bathroom, and secondly, the bathing time for each time of entering the bathtub (for example, the duration in which the water level detected by the water level sensor 6 is above a predetermined level) ), 3rd, accumulated bathing time obtained by accumulating multiple bathing times, 4th, silence time in the bathtub (sleeping time), 5th, staying time outside the bathtub in the bathroom included.

  (10) A plurality of timer functions used for each time measurement are provided, and it is only necessary to select time setting and use / non-use.

  (11) The threshold value may be reviewed as a reference value for detecting the water level or voice, such as the water level value before bathing or the volume of the unmanned state, and stored in the memory unit 50-1, for example, and may be learned and updated as needed. Thereby, precise bathing management becomes possible.

  (12) In this bathing management apparatus 2, for example, a water level detecting means for detecting the hot water level in the bathtub, a sound detecting means for detecting the sound in the bathroom, first detection information detected by the water level detecting means, and a sound detecting means What is necessary is just to set it as the structure provided with the measurement means which measures a bather's state with the 2nd detection information detected by this.

  (13) Sensor functions such as a water level sensor 6 and a microphone 4 provided in a heat source device such as a general water heater can be used, and the status of each bather in the bathroom can be ascertained based on information obtained from the sensor function. Time can be counted or accumulated, and the results can be notified to the bather of necessary warnings such as a situation or awakening from a dozing state using an information presentation function such as a display unit or a speaker. In addition to detecting the human body using the water level sensor 6 and the microphone 4, an alert function for bathing for a long time and for preventing dozing can be obtained.

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

  (15) Use of special sensors or proprietary information monitoring to grasp the bather's situation leads to increased costs, which may cause problems such as false detection. In the embodiment, this can be avoided.

  (16) The detection information obtained from the microphone 4 and the water level sensor 6 provided in the existing heat source machine can be used to grasp the bather's situation, and the detection information can be accumulated and the history thereof can be stored. The judgment result can be used to increase the safety of the bather, such as warning the bather as an alert or notifying the manager.

  (17) Management that associates information obtained at the time of bathing with identification information of a bather, stores it in one or more of the memory units 50-1, 50-2, and 50-3, stores it, and manages it for each bather It is good also as a form.

<Other embodiments>

  FIG. 14 shows the state transition of the bathing management apparatus according to another embodiment. In this embodiment, the no bathing state 102, the bathroom entering state 104, the bathing bath state 106, the dozing warning notification state 108, and the entering / bathing detection prohibition state 110 are set as the bathing management state.

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

  If the bathtub water level rises from the bathroom entry state 104 (S404), the state transitions to the bathtub entry state 106. In this bathing state 106, bathing is displayed on the bathroom remote control device 28 and the kitchen remote control device 30 (S405). If the bathtub water level falls from this bathtub bathing state 106 (S406), it changes 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 in the no bathing state 102, if an increase in the bathtub water level is detected (S407), the bathroom entering state 104 is skipped and the bath transitions to the bathing state 106.

  If the state without sound detection from the bathing state 106 is the predetermined time T2, for example, if T2 = 10 [minutes] has elapsed (S408), the state transitions to the dozing warning notification state 108. When transitioning to the dozing warning notification state 108, at least a bathing warning is notified to the bather. If, for example, T3 = 30 [seconds] has elapsed as the predetermined time T3 from this dozing warning notification state 108 (S409), the transition from the dozing warning notification state 108 to the bathing state 106 is made. If the bather performs a notification stop operation in the dozing warning notification state 108 (S410), the bathing state 106 is returned from the dozing warning notification state.

  If the bathtub water level falls in this dozing warning notification state 108 (S411), the bathing state 106 is skipped and the bathing state 104 is returned to. That is, if the bather leaves the bathtub 20 without performing the notification stop operation, it can be determined that the dozing state has been eliminated.

  In the bathroom entry state 104, bathing bath state 106 or dozing warning notification state 108, if the entry / release detection operation is performed by operating the bathroom remote control device 28 (S412, S413, S414), the entry / bathing detection prohibited state 110 is entered. Transition.

  Even if such an entry / bathing detection canceling operation is performed, if an entry / bathing detection start operation is performed from the entry / bathing detection prohibited state 110 (S415), the state transits to the bathroom entry state 104.

  Further, for example, when T4 = 1 [time] has elapsed as the predetermined time T4 from the transition point of the room entry / bathing detection prohibited state 110 (S416), the room entry / bathing detection prohibited state 110 transits to the no bathing state 102.

  FIG. 15 shows a procedure for 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, the presence or absence of bathroom sound is determined (S501). If there is a bathroom sound (YES in S501), it is determined whether the bathtub water level has risen (S502). If there is no bathroom sound (NO in S501), for example, it is determined whether the predetermined time T1 from the detection of the bathroom sound is within T1 = 5 [minutes] (S503). If T is not within 5 minutes (NO in S503), the process returns to S501. If T1 = within 5 minutes (YES in S503), the process of S502 is performed.

  If the bath water level rises (YES in S502), it is determined that there is a bath (S504), and the presence of a bath is displayed (S505). If there is no rise in bathtub water level (NO in S502), the process returns to S501.

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

  A bathroom sound is determined (S507). If there is no bathroom sound (NO in S507), a change in bathtub water level is determined (S508). If there is no change in the bathtub water level (YES in S508), for example, if the measurement time T2 of the timer function 72-4 has passed T2 = 10 [minutes] (YES in S509), a dozing prevention warning sound is generated. (S510). For example, it is determined whether T3 = 30 [seconds] has elapsed as the predetermined time T3 from the start of the dozing prevention warning sound. If T3 = 30 [seconds] has elapsed (YES in S511), the dozing prevention warning sound is stopped (S512). Even before T3 = 30 [seconds] has elapsed (NO in S511), if there is a stop operation of the dozing prevention warning sound (YES in S513), the dozing prevention warning sound is stopped (S512). If there is no operation for stopping the dozing prevention warning sound (NO in S513), the process returns to S510, and the generation of the dozing prevention warning sound is continued.

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

  If there is a bathroom sound in S507 (YES in S507), or if there is a water level fluctuation in the bathtub (NO in S508), the time measurement of the timer function 72-4 is restarted, and the measurement time is remeasured (S515), A drop in the water level of the bathtub is determined (S516). If there is no drop in the water level in the bathtub (NO in S516), the process returns to S507.

  If there is a drop in the water level in the bathtub (YES in S516), an increase in the water level in the bathtub is determined (S517). If there is a rise in the water level in the bathtub (YES in S517), the process returns to S506, and the processes in S506 and subsequent steps are executed.

  If there is no rise in the water level in the bathtub (NO in S517), it is determined whether the state of no bathroom sound is equal to or longer than a predetermined time T1, for example, T1 = 5 [minutes] (S518). If the state where there is no bathroom sound continues for T = 5 [minutes] or longer (NO in S518), the process returns to S517.

  If bathing starts while it is determined whether the bathroom sound is absent for 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 the processes of S506 and thereafter are executed.

  If the state where there is no bathroom sound continues for T = 5 [minutes] or longer (NO in S518), the process returns to S517. Moreover, if the state where there is no bathroom sound continues for T = 5 [min] or more (YES in S518), it is determined that there is no bathing (S519), the display indicating that there is no bathing is canceled (S520), and this process is terminated. To do.

<Effects of other embodiments>

  According to the other embodiments, the following effects can be obtained.

  (1) The bath water level and bathroom sound are used together for bathing management of the bather, so that the human body detection and bathing situation of the bather in the bathroom 14 can be accurately grasped, and the safety of the bather can be improved from a doze state or long bathing. Can be increased.

  (2) Bathing detection is performed based on the bath water level or its change, and silence such as a bather's sleep can be quickly detected by collecting sound from the microphone 4.

  (3) An existing microphone mounted on the bathroom remote control device 28 can be used as the microphone 4, and it is not necessary to install a new microphone to realize the above embodiment. In addition, the display units 66-1, 66-2 and the speakers 62-1 and 62-2 in the bathroom remote control device 28 and the kitchen remote control device 30 can be used for information presentation, such as warning display, melody, language, etc. The voice guidance can notify bathers and managers of warnings and the like, and the safety of bathers can be improved.

  (4) In addition to bathing detection by the water level sensor 6, the bathing state can be complemented by voice detection by the microphone 4, so there is no sufficient rise in water level compared to the conventional bathing management in which the bathing state is grasped only by raising the water level. Even if it is a case, a bathing state can be grasped | ascertained and the response | compatibility according to the condition is attained. For example, in the case of half-body bathing or a child, the rise level of the bathtub water level is small, and the bather may not be able to discriminate whether the bather is inside or outside the bathtub only by the bathtub water level. It is possible to accurately grasp the staying place and the bathing situation such as bathing, whether the bather is a child, or whether it is out of the bathtub and in the washing place. The notification function for bathers and managers and their variations can be controlled based on the understanding of the bathing situation.

  (5) In addition to bathing detection by the water level sensor 6, the bathing state can be complemented by voice detection by the microphone 4, so even if the change in the bath water level is small, abnormalities such as a bather's dozing state or fainting state can be grasped It can be done quickly.
