Therefore, the atmosphere side of the pressure receiving portion is opened to the outside of the bathroom (atmosphere) by the breather pipe 5a (see FIG. 1).
[0053]
The heartbeat electrode 6 is provided in the bathtub B as shown in FIG. Specifically, the heart rate electrodes 6a and 6b are provided on both sides of the bather immersed in the hot water stored in the bathtub B, that is, on the left and right side walls of the bathtub B. The heartbeat electrode 6c is provided on a side wall on one end side of the bathtub B. The heart rate electrodes 6a, 6b, 6c are arranged at substantially the same height. The heartbeat signal detected by the heartbeat electrode 6 is sent to the signal processing unit 46 of the measuring device 4.
[0054]
Next, a control operation in the bathroom system will be described with reference to a flowchart shown in FIG. Here, when there is an abnormality in the heart rate of the bather, the abnormality is immediately notified.
[0055]
First, the measuring microcomputer 43 determines whether or not the water level in the hot and cold water in the bathtub B has risen sharply (S1). Specifically, the detection output of the water level sensor 5 is monitored, and a determination is made based on whether or not a predetermined amount of water level change has occurred within a predetermined time (for example, 2 seconds). Thus, the measurement-side microcomputer 43 can detect whether or not the bather has entered the bathtub B.
[0056]
In step S1, when it is determined that there is a sudden rise in the water level and the bather has entered the bathtub B (S1: YES), the measurement microcomputer 43 determines whether a heartbeat signal has been detected (S2). . That is, the measurement-side microcomputer 43 performs this determination by monitoring the heartbeat signal detected by the heartbeat electrode 6.
[0057]
When no heartbeat signal is detected (S2: NO), the measurement-side microcomputer 43 determines whether or not a predetermined time has elapsed (S3). When the predetermined time has elapsed (S3: YES), the process returns to step S1. That is, here, it is recognized that, for example, a mat for a bathtub or a chair for a bathtub other than the bather has been put in the bathtub B. If the predetermined time has not elapsed (S3: NO), the process returns to step S2.
[0058]
Next, the measurement microcomputer 43 determines whether or not the water level in the bathtub B has dropped sharply (S4). Specifically, the detection output of the water level sensor 5 is monitored, and a determination is made based on whether or not a predetermined amount of water level change has occurred within a predetermined time. Thereby, the measurement-side microcomputer 43 can infer that the bather has left the bathtub B.
[0059]
When determining that there has been a sharp drop in the water level (S4: NO), the measurement-side microcomputer 43 determines whether or not a heartbeat signal is detected (S5), and when no heartbeat signal is detected (S5: NO), It is determined that the bather has left bathtub B (S6). That is, when there is a sharp drop in the water level and no heartbeat signal is detected, the measurement-side microcomputer 43 determines that the bather has left the bathtub B, and ends this processing.
[0060]
On the other hand, when it is determined in step S4 that there is no sharp drop in the water level (S4: YES), or when a heartbeat signal is detected in step S5 (S5: YES), the measurement-side microcomputer 43 causes the signal processing unit 46 to A heart rate signal converted into a predetermined digital signal is taken in, and a heart rate per predetermined time (for example, one minute) based on the heart rate signal is obtained. Then, it is determined whether or not the obtained heart rate is abnormal (S7).
[0061]
When there is no abnormality in the heart rate (S7: YES), the information of the obtained heart rate is sent to the hot water supply apparatus main body 1 via the communication unit 42 and the two-core cable 7. Hot water supply device main body 1 transmits heart rate information to bathroom remote controller 3 via communication unit 14 and two-core cable 7. The bathroom-side microcomputer 35 of the bathroom remote controller 3 displays the information on the heart rate sent from the measuring device 4 on the display unit 33 together with the heart symbol as shown in FIG. 4 (S8). Thereafter, the process returns to step S4. The information on the heart rate is sent from the measuring device 4 to the kitchen remote controller 2 via the hot water supply device main body 1, and is displayed on the display unit 23 by the kitchen microcomputer 25 of the kitchen remote controller 2 as shown in FIG. It may be displayed together with the mark. Further, in the present embodiment, the measuring device 4 is communicably connected to the kitchen remote controller 2 and the bathroom remote controller 3 via the water heater main body 1, but the measuring device 4 is communicable with the kitchen remote controller 2 and the bathroom remote controller 3. The remote controller 2 may be connected to transmit the heart rate information measured by the measuring device 4 directly to the kitchen remote controller 2 and the bathroom remote controller 3.
[0062]
On the other hand, if there is an abnormality in the heart rate in step S6 (S7: NO), information indicating that there is an abnormality is transmitted to the kitchen remote controller 2 via the water heater main body 1. The kitchen microcomputer 25 of the kitchen remote controller 2 displays the abnormality information sent from the measuring device 4 on the display unit 23 (S9). Alternatively, it outputs sound indicating that there is an abnormality through the speaker 24e. As described above, since an abnormality is notified not only to the sight but also to the auditory person, the person other than the bather immediately knows that the condition of the bather has become abnormal. be able to.
[0063]
The abnormality information may be sent from the measuring device 4 to the bathroom remote controller 3 via the hot water supply device main body 1 and displayed on the display unit 33 by the bathroom microcomputer 35 of the bathroom remote controller 3 or a speaker. It may be configured to output a sound indicating that there is an abnormality through 34g.
[0064]
Here, the conditions when the measuring microcomputer 43 determines that the heart rate is abnormal will be described. When the heart rate of the bather suddenly increases or decreases, it is determined that the heart rate is abnormal. Further, after the water level of the hot water in the bathtub B once rises, if the heart rate cannot be detected despite the fact that the water level of the hot water does not decrease, it is determined that there is a possibility of cardiac arrest. It is determined that there is. Further, when the heart rate is out of the predetermined range, it is determined that the heart rate is abnormal. When any one of these conditions is satisfied, it may be determined that the heart rate is abnormal, or when a plurality of conditions are satisfied, it may be determined that the heart rate is abnormal. .
[0065]
As described above, according to the present embodiment, the heart rate signal of the bather who is immersed in the hot water in the bathtub B is detected, and the heart rate is measured from the heart rate signal. Since the remote controller 2 and the bathroom remote controller 3 are notified of the abnormality, it is possible to notify a person other than the bather of the state of the bather. For example, a person other than the bather who was in the kitchen can surely know that the heart rate of the bather has occurred by the display on the kitchen remote controller 2, and for example, immediately go to the bathroom to protect the bather. it can. That is, a bathroom system with improved safety can be provided.
[0066]
Further, according to this embodiment, when there is an abnormality in the heart rate, the bather can automatically notify a person other than the bather without, for example, pressing the call switch 34f by himself / herself. Further, according to the above-described embodiment, it is possible to determine whether a bather enters or exits the bathtub B by detecting a sudden change in the water level in the bathtub B. Since the number is detected, the possibility of erroneous detection when detecting the heart rate can be suppressed.
[0067]
<Second embodiment>
FIG. 7 is a schematic configuration diagram illustrating a bathroom system according to a second embodiment of the present invention. The bathroom system according to the second embodiment is characterized in that when there is an abnormality in the heart rate of a bather, the hot water in the bathtub B is controlled to be immediately drained.
[0068]

Its opening and closing are controlled. Other configurations are substantially the same as those of the first embodiment.
[0069]
In the bathroom system of this configuration, in FIG. 6, a flowchart in which a step of performing hot and cold water drainage processing is added after step S8 is applied, and when there is an abnormality in the heart rate, it is only notified by display or voice. Instead, the water in the bathtub B is drained immediately. That is, when the measurement microcomputer 43 determines that the heart rate is abnormal (step S6: NO in FIG. 6), the measurement microcomputer 43 transmits the fact to the main body microcomputer 12 via the two-core cable 7. When the main body side microcomputer 12 receives a signal indicating that there is an abnormality in the heart rate from the measurement side microcomputer 43, the main body microcomputer 12 transmits the signal to the kitchen remote controller 2 to display the abnormality information on the display unit 23, and outputs a sound through the speaker 24e. The automatic drain plug 51 is changed from the closed state to the open state, and the hot water in the bathtub B is controlled to be immediately drained.
[0070]
In this way, when the bather is taking a bath in the bathtub B, for example, when the bather loses consciousness, it is possible to prevent the bather from drowning in the bathtub B.
[0071]
<Third embodiment>
FIG. 8 is a diagram showing an electrical configuration of a bathroom system according to the third embodiment of the present invention. In the above-described first or second embodiment, the abnormality is notified to the outside based on the fact that the heart rate measured by the measuring device 4 is abnormal. In the third embodiment, the respiration of the bather is stopped. An abnormality notification is issued to the outside based on the judgment.
[0072]
The measurement-side microcomputer 43 determines whether the bather has stopped breathing based on the periodic fluctuation of the water level in the bathtub B detected by the water level sensor 5. That is, since the bather who is immersed in the hot water in the bathtub B normally breathes while taking a bath, the surface of the hot water in the bathtub B undulates in response to the breathing and continues normal breathing. Then, the level of the hot and cold water in the bathtub B periodically fluctuates. Therefore, by detecting the periodic fluctuation of the water level by the water level sensor 5, it can be determined whether or not the bather is breathing.
[0073]
In addition, in the third embodiment, as shown in FIG. 8, the measuring device 4 includes a water level fluctuation analysis unit 52 and a heart rate fluctuation analysis unit 53. The water level fluctuation analysis section 52 connects the water level sensor 5 and is connected to the I / O section 45. The heart rate variability analysis section 53 connects the plurality of heart rate electrodes 6 and is connected to the I / O section 45.
[0074]
The water level fluctuation analysis unit 52 analyzes the frequency component of the water level fluctuation waveform based on the water level fluctuation of the hot water in the bathtub B detected by the water level sensor 5. The water level fluctuation waveform is a waveform that indicates the temporal displacement of the water level that fluctuates due to the breathing of the bather. Since the water level fluctuates due to the bather's breathing, the water level repeatedly rises and falls in response to the bather's inhaling and exhaling actions. The signal indicating the water level fluctuation detected by the water level sensor 5 is a signal that fluctuates in a sinusoidal manner, but includes a distorted waveform and thus includes other frequency components in addition to the fundamental frequency corresponding to the respiratory cycle. It has become. The water level fluctuation analysis unit 52 is configured by, for example, a spectrum analyzer or an FFT (Fast Fourier Transform) analyzer, and extracts a frequency component included in a signal indicating the water level fluctuation.
[0075]
The heart rate variability analysis unit 53 analyzes a frequency component included in the heart rate signal output from the signal processing unit 46. It is known that the heart rate fluctuates so as to increase in response to a bather's inhaling operation and to decrease in response to an exhaling operation. Therefore, the heartbeat signal output from the signal processing unit 46 is a signal whose frequency fluctuates up and down in accordance with the breathing motion of the bather (a signal similar to a signal FM with a signal having a cycle of the breathing motion). ing. The heart rate variability analysis unit 53 also includes, for example, a spectrum analyzer or an FFT analyzer, and extracts a frequency component included in the heart rate signal.
[0076]
The measurement-side microcomputer 43 compares the frequency component of the heartbeat waveform obtained by the heartbeat variability analysis unit 53 with the frequency component of the water level waveform obtained by the water level variability analysis unit 52, and in both cases, the breathing of the bather It is determined whether there is a frequency component corresponding to the operation cycle (hereinafter, this frequency component is referred to as a synchronization component). Then, different notifications are given to the user based on the presence or absence of the synchronization component (described later).
[0077]
FIG. 9 is a flowchart illustrating a control operation of the bathroom system according to the third embodiment. The control operation in the figure has the same parts as the control operation in FIG. 6, that is, steps S1 to S6 in FIG. 6 and steps S11 to S16 in FIG. 9 are the same. Will be described.
[0078]
If there is no sharp drop in the water level in step S14 (S14: YES), or if a heartbeat signal is detected in step S15 (S15: YES), the measuring microcomputer 43 sets the bathtub B on the basis of the detection output of the water level sensor 5. It is detected whether or not there is a periodic fluctuation in the level of the hot and cold water stored therein (S17). That is, when a bather enters the bathtub B and is immersed in hot water, the vibration caused by the bather's breathing is normally transmitted to the hot water and appears as a periodic fluctuation in the water level. Therefore, even if it is determined that the bather has entered the bathtub B, if there is no periodic change in the water level, it is determined that the bather has stopped breathing.
[0079]
If the measuring microcomputer 43 determines in step S17 that there is no periodic change in the water level of the hot water based on the detection output of the water level sensor 5 (S17: NO), it determines that the bather has stopped breathing ( S18), an abnormal display is made on the display unit 23 of the kitchen remote controller 2 and the display unit 33 of the bathroom remote controller 3 (S19). Further, an abnormal sound is output through the speaker 24e or the speaker 34g. The abnormal display and abnormal sound output in this case are dangerous states such as the breathing of the bather has stopped and are urgent, so that the abnormal display blinks and the abnormal sound is output or a relatively loud sound is output. It is desirable. Thus, a dangerous state such as the stoppage of breathing of the bather can be immediately notified to a person other than the bather, and a person other than the bather can take a prompt response.
[0080]
When the abnormality is notified in step S19, the end-end microcomputer 12 may control the automatic drain plug 51 from the closed state to the open state to immediately drain the hot water in the bathtub B.
[0081]
On the other hand, if it is determined in step S17 that there has been a periodic water level fluctuation (S17: YES), the water level fluctuation analysis unit 52 analyzes the water level waveform based on the water level signal detected by the water level sensor 5, and obtains the water level waveform. Is obtained (S20). Next, the heartbeat variability analysis unit 53 analyzes the heartbeat waveform based on the heartbeat signal detected by the heartbeat electrode 6, and obtains the frequency component of the heartbeat waveform (S21).
[0082]
Thereafter, the center frequency of the water level waveform obtained by the water level fluctuation analysis section 52 is compared with the center frequency of the heart rate waveform obtained by the heart rate fluctuation analysis section 53 to determine whether or not there is a synchronous component (S22).
[0083]
If there is a synchronous component (S22: YES), it is determined whether or not the heart rate is abnormal (S23). That is, the measurement microcomputer 43 determines whether or not the heart rate detected by the heartbeat electrode 6 and obtained by the measurement device 4 is abnormal.
[0084]
When there is no abnormality in the heart rate (S23: YES), the heart rate of the bather is displayed on the display unit 23 of the kitchen remote controller 2 and the display unit 33 of the bathroom remote controller 3 (S24), and the process returns to step S14.
[0085]
On the other hand, when there is an abnormality in the heart rate (S23: NO), an abnormality is displayed on the display unit 23 of the kitchen remote controller 2 and the display unit 33 of the bathroom remote controller 3 (S25). The abnormal display in this case is different from the abnormal display when the breathing is stopped, and is not a display that indicates a dangerous state such as the stop of the breathing, but rather a slightly abnormal display that the heart rate is abnormal. It is said. In step S22, when there is no synchronous component (S22: NO), an abnormal display indicating that there is a possibility of an accident in some cases, such as a mismatch between the respiration and the heart rate, is performed (S26).
[0086]
In this manner, it is possible to determine whether or not the bather's breathing has stopped based on the presence or absence of a periodic change in the water level in the bathtub B. For example, when the bather's breathing has stopped, Since the notification is larger than the normal abnormality notification, the person other than the bather can immediately know the state of the bather, and can take prompt action.
[0087]
<Fourth embodiment>
FIG. 10 is a schematic configuration diagram illustrating a bathroom system according to a fourth embodiment of the present invention. The difference between this bathroom system and the bathroom system of the above embodiment is that a human body detection sensor 54 is provided in the bathroom, and the human body detection sensor 54 is used to more finely detect the movement of the bather, If there is an abnormality in consideration of the trend and the heart rate, the fact is notified to the outside.
[0088]
The human body detection sensor 54 is provided near the ceiling of the bathroom, and is configured by, for example, an imaging sensor using a CCD image sensor, and the presence of a bather or a movement of the bather in the bathroom (whether the person has entered the bathtub B or This is for detecting whether or not it has come out of the bathtub B). The human body detection sensor 54 is connected to the measurement-side microcomputer 43 of the measuring device 4 via an I / O unit 45 and an imaging signal recognition unit (not shown). The detection signal detected by the human body detection sensor 54 is The signal is recognized by the signal recognition unit, and the recognition signal is transmitted to the measurement microcomputer 43. Other configurations are substantially the same as those in the above embodiment. The imaging signal recognition unit recognizes, for example, whether a moving object is present in the bathroom from a change in the captured image. When no person is in the bathroom, the captured image is usually in a still image state, so the imaging signal recognition unit checks the periodically input captured images, and when a change in the image is detected, Recognizes that a moving object (bather) has entered the bathroom. Conversely, when a state in which the image has changed is detected from a state in which the image has changed, it is recognized that the moving object (bather) has left the bathroom.
[0089]
FIG. 11 is a flowchart showing a control operation of the bathroom system according to the fourth embodiment. According to the figure, the measurement-side microcomputer 43 determines whether or not the bather has entered the bathroom (S31). Specifically, the measurement-side microcomputer 43 determines whether a bather enters the room based on the detection output of the human body detection sensor 54.
[0090]
When determining that the bather has entered the bathroom (S31: YES), the measurement-side microcomputer 43 determines whether the bather is taking a bath (S32). Specifically, the measurement-side microcomputer 43 monitors the detection output of the water level sensor 5 and, based on the fact that the water level sensor 5 detects a sudden rise in the water level, that the bather has entered the bathtub B, that is, It is determined that it is inside. The measurement-side microcomputer 43 repeats the process of step S31 until it is determined that the bather has entered the bathroom.
[0091]
When it is determined that the bather is taking a bath (S32: YES), the measurement-side microcomputer 43 determines whether or not the bather is moving (S33). Specifically, the measurement-side microcomputer 43 monitors the detection outputs of the human body detection sensor 54 and the imaging signal recognition unit, and makes a determination based on the detection of the movement of the bather by the human body detection sensor 54.
[0092]
If it is determined that the bather has moved (S33: YES), the heartbeat of the bather is detected (S34). That is, the heart rate of the bather is obtained based on the detection output of the heart rate electrode 6 in the measuring device 4. As described above, if the heart rate is measured after detecting that there is no movement in the bathtub B of the bather, the heartbeat electrode 6 has good noise with little noise because there is no movement in the bathtub B of the bather. Since the heartbeat signal can be detected more accurately by taking in the heartbeat signal, the accuracy of the abnormality notification can be further improved. On the other hand, when it is not determined that there is a movement of the bather (S33: NO), the process returns to step S31.
[0093]
Next, the measurement-side microcomputer 43 determines whether or not the measured heart rate is within a predetermined range (S35). Here, the predetermined range generally refers to a range of the heart rate at which the heart rate can be determined to be normal. If the measured heart rate is out of the predetermined range (S35: NO), that is, if the bather is taking a bath and there is no movement of the bather, and the heart rate is out of the predetermined range Then, it is determined that some abnormality has occurred in the bather, and the hot water in the bathtub B is drained (S36). That is, the measurement-side microcomputer 43 transmits to the body-side microcomputer 12 that the bather has some abnormality. When the main body side microcomputer 12 receives a signal indicating that the heart rate is abnormal from the measurement side microcomputer 43, it controls the automatic drain plug 51 from the closed state to the open state to immediately drain the hot water in the bathtub B. I do.
[0094]
Thereafter, the measurement-side microcomputer 43 causes the display unit 23 of the kitchen remote controller 2 and the display unit 33 of the bathroom remote controller 3 to display an abnormality, and informs that the speaker 24e of the kitchen remote controller 2 and the speaker 34g of the bathroom remote controller 3 have generated an abnormality. The sound is output (S37). In addition, since it is also assumed that the abnormal display in this case is in a dangerous state, for example, the bather has lost consciousness, it is desirable to perform a relatively large abnormality notification.
[0095]
In step S35, when the measured heart rate is within the predetermined range (S35: YES), the measuring microcomputer 43 compares the heart rate measured during the current bathing with the heart rate measured during the previous bathing. To determine whether there is an abnormal change in the heart rate (S38). That is, the measuring microcomputer 43 stores the heart rate measured at the previous bathing in the EEPROM 44, measures the heart rate at the current bathing, and reads the heart rate measured at the previous bathing from the EEPROM 44. . Then, the two are compared to determine whether or not the difference is less than a predetermined value. Here, the predetermined value refers to a value in which the variation range of the heart rate is within a normal range.
[0096]
When the measurement-side microcomputer 43 determines that the difference between the heart rate measured during the current bath and the heart rate measured during the previous bath is less than a predetermined value (S38: NO), the display of the kitchen remote controller 2 is performed. The heart rate is displayed on the unit 23 and the display unit 33 of the bathroom remote controller 3 (S39).
[0097]
When the measurement-side microcomputer 43 determines that the difference between the heart rate measured during the current bath and the heart rate measured during the previous bath is equal to or greater than a predetermined value (S38: YES), the heart rate changes. It is determined whether the cause is the water temperature or the water level (S40). That is, when the difference between the heart rate at the time of the previous bath and the heart rate at the time of the current bath is large, the measurement-side microcomputer 43 performs the current bath regardless of whether the difference does not increase if the bath is a normal bath. We guess that the difference may have increased, cite water temperature and water level as the cause of the difference, and confirm those values at the time of this bathing. Then, based on the confirmation result, it is determined whether or not the cause of the change in the heart rate is the water temperature or the water level.
[0098]
If the water temperature and water level in this bathing are appropriate values for normal bathing, it is determined that the cause of the heart rate change is not the water temperature and water level (S40: NO), that is, the heart rate changes. It is determined that the cause is the bather himself, and the bather is determined to be in an abnormal state, and the fact is displayed abnormally on the display unit 23 of the kitchen remote controller 2 and the display unit 33 of the bathroom remote controller 3 (S41). Thus, for example, a user in the kitchen can recognize that the bather has an abnormality, and can immediately go to the bathroom to protect the bather, for example.
[0099]
On the other hand, if the water temperature or water level at the time of this bathing is not an appropriate value for normal bathing, it is determined that the cause of the change in heart rate is the water temperature or water level (S40: YES), and the heart rate rises. Is performed (S42). Specifically, the measurement-side microcomputer 43 sends a command signal to that effect to the body-side microcomputer 12 of the hot-water supply device body 1, and the body-side microcomputer 12 supplies water into the bathtub B, for example, to set an appropriate hot water temperature or the like. Control so that the water level is appropriate. After this processing, the measurement-side microcomputer 43 displays the heart rate in step S39.
[0100]
As described above, when the difference between the heart rate measured at the time of bathing this time and the heart rate measured at the time of previous bathing is equal to or greater than a predetermined value, it is determined whether or not the cause of the difference is the bather himself. If the cause of the difference is due to the bather himself, the abnormality notification is performed, so that highly accurate discrimination according to each bather can be performed.
[0101]
As described above, when the human body detection sensor 54 and the heartbeat electrode 6 are used in combination, the heartbeat electrode 6 detects the heartbeat signal of the bather while the bather is stationary in the bathtub B. If the bather is stationary, the bather 54 may erroneously detect that the bather is not in the bathroom. However, according to the above embodiment, in steps S32 and S33, the heart rate is detected when the bather is taking a bath and there is no movement of the bather, so that the possibility of occurrence of the erroneous detection is avoided. can do.
[0102]
Also, the number of bathers entering bathtub B is not limited to one. Therefore, in order to read out the heart rate at the time of the last bathing, the measuring microcomputer 43 may store the heart rate at the time of the last bathing for each of a plurality of bathers. More specifically, the bather can input an ID code indicating that he / she is himself / herself through the operation unit 34 of the bathroom remote controller 3 in advance. The number and its ID code may be stored.
[0103]
Returning to FIG. 11, when it is determined in step S32 that the bather is not taking a bath (S32: NO), the measurement microcomputer 43 determines whether or not the bather is moving (S43). Specifically, the measurement-side microcomputer 43 monitors the detection output of the human body detection sensor 54, and makes a determination based on the fact that the human body detection sensor 54 detects the movement of the bather.
[0104]
When it is determined that the bathing person is not bathing and there is no movement of the bather (S43: YES), the measuring microcomputer 43 recognizes that the bather has experienced an abnormality for some reason, and displays the display unit 23 of the kitchen remote controller 2 and the bathroom. That fact is displayed on the display unit 33 of the remote controller 3 (S44). Accordingly, for example, a person other than the bather in the kitchen can recognize that the bather has an abnormality, and can immediately go to the bathroom and protect the bather, for example. If it is determined in step S43 that the bather has moved (S43: NO), the process returns to step S32.
[0105]
<Fifth embodiment>
By the way, as shown in FIGS. 3 and 4, the bathroom-side remote controller 3 and the kitchen remote controller 2 are provided with communication switches 24d and 34f for communicating with the other party. In this bathroom system, when a person other than the bather wants to talk with the bather in the bathroom from the kitchen remote controller 2, by pressing the call switch 24d, the person other than the bather in the kitchen and the bather thereafter. In this case, a call can be made between the kitchen remote controller 2 and the bathroom remote controller 3 without any special operation. On the other hand, when the bather wants to talk to a person other than the bather in the kitchen from the bathroom remote controller 3, after pressing the call switch 34 f, the person other than the bather presses the call switch 24 d from the kitchen remote controller 2 for the first time. Calls are allowed.
[0106]
This usually means that when a person other than the bather calls from the kitchen to the bather, it is clear that the bather is in the bathroom, while the bather talks to a person other than the bather in the kitchen. In this case, it is because the person other than the bather is not necessarily in the kitchen.
[0107]
According to the bathroom system having such a communication method, for example, when the condition of the bather deteriorates and the call switch 34f cannot be pressed, the bather changes his / her own state to, for example, a bath in the kitchen. May not be able to tell others.
[0108]
Therefore, in order to solve such a problem, in the fifth embodiment, when the measuring device 4 measures an abnormal heart rate of a bather, control is performed so that a telephone call can be immediately made. Specifically, when the measuring device 4 measures the abnormal heart rate of the bather, the bather can talk between the bathroom remote controller 3 and the kitchen remote controller 2 without pressing the call switch 34f. You.
[0109]
In this way, even if the bather cannot press the call switch 34f, for example, if he / she speaks to seek help from a person other than the bather, the bather's state is immediately changed. Can be notified to those who are outside the bathroom.
[0110]
Note that the scope of the present invention is not limited to the above-described embodiment. For example, the number of remote control devices connected to hot water supply device main body 1 is not limited to the above embodiment. According to the above-described embodiment, the measuring device 4 measures the heart rate of the bather. In addition, the measuring device 4 may calculate the body fat percentage of the bather based on the output from the water level sensor 5. Good. In addition, the data signal between the water heater unit 1, the kitchen remote controller 2, the bathroom remote controller 3, and the measuring device 4 was transmitted and received between the respective devices through a wire such as a two-core cable 7, but instead of the data signal, the data signal was transmitted wirelessly. May be transmitted and received.
[0111]
【The invention's effect】
According to the present invention, a heartbeat signal of a bather who is immersed in hot water in a bathtub is detected, a heart rate is measured from the heartbeat signal, and when there is an abnormality in the heart rate, an abnormality is notified in the remote control device. Therefore, it is possible to notify a person other than the bather of the state of the bather. For example, if the remote control device is provided in a kitchen or the like, a person other than the bather in the kitchen can surely know that the heart rate of the bather has occurred, and, for example, immediately go to the bathroom and take a bath. Thus, a bathroom system with improved safety can be provided. In addition, when the heart rate of the bather is abnormal, the hot water in the bathtub is drained, so that a serious accident can be prevented from occurring in the bather. Further, according to the bathroom system, when there is an abnormality in the heart rate, the bather can automatically notify a person other than the bather without, for example, pressing the call switch by himself / herself.
