A controller 2 for controlling the operation of the hot water supply unit 1 is provided, and further, a bath remote controller 3, a kitchen remote controller 4, etc., which are connected to the controller 2 so as to be able to communicate with each other, are provided to configure an automatic hot water bath. ing.
The bath remote controller 3 is installed on the side wall of the bathroom 9.

A water level sensor 7 for detecting the water level in the bath 5 is provided, and the information detected by the water level sensor 7 is input to the controller 2. The water level sensor 7 is specifically composed of a pressure sensor provided at a location where the hot water supply passage 6 communicates with the bath 5. That is, when the water level in the bathtub 5 rises, the pressure detected by the pressure sensor increases, so that the water level in the bathtub 5 is detected based on the detected pressure value. Therefore, the water level sensor 7 detects the state of the hot water in the bathtub 5 by the water level sensor 7.
And the water pressure detecting means 102 for detecting the pressure of the hot water in the bathtub 5. That is, bathtub 5
The water level inside is detected as the state of the hot water in the bathtub 5.

Further, for example, when the bather performs an operation of stirring the hot and cold water in the bathtub 5 by hand to generate waves on the surface of the hot water, the water level sensor 7 composed of a pressure sensor causes
Since the bather's motion is detected as a change in the water level or pressure of the hot water in the bathtub 5, the water level sensor 7 constitutes the motion detecting means 103 for detecting the motion of the bather in the bathroom 9. .

As shown in FIG. 2, the bath remote controller 3 has a control section 30 communicatively connected to the controller 2, and a display for displaying various information in a state of being connected to the control section 30. Part 31, speaker 32 as acoustic means for emitting sound into bathroom 9, up-down type change key 33, operation switch 34, automatic water filling switch 35
Etc. are provided. Although not shown, the kitchen remote controller 4 has the same configuration as the bath remote controller 3. The speaker 32 of the kitchen remote controller 4 constitutes an outside-bath acoustic means for emitting sound to the outside of the bathroom 9. The ceiling of the bathroom 9 is provided with a lighting unit 8 that illuminates the interior of the bathroom 9. The lighting means 8 is composed of a light bulb or the like, and is driven by the controller 30 of the bath remote controller 3 so that the illuminance can be adjusted.

Further, on the ceiling of a washroom (not shown) in front of the bathroom 9, an outside-bathroom illumination means 15 for illuminating the outside of the bathroom 9 (in this case, the washroom) is provided.
The exterior lighting means 15 is composed of a light bulb or the like, and is driven by the controller 30 of the bath remote controller 3 so that the illuminance can be adjusted.

Using the control unit 30 of the bath remote controller 3, based on bathroom information detected in the bathroom 9,
The control means 100 is configured to execute adjustment control for adjusting the characteristics of the sound emitted into the bathroom 9 by the speaker 32 and the characteristics of the illumination in the bathroom 9 illuminated by the illumination means 8. Then, the control means 100 executes the adjustment control by using the detection information of the state of the hot and cold water in the bathtub 5 detected by the hot and cold water state detecting means 101 (water level sensor 7) as the bathroom information. It is configured.

The adjustment of the acoustic characteristics based on the detection information of the state of the hot water will be explained. Specifically, when it is confirmed that the bather is taking a bath by operating the bath remote controller 3, etc. The sound of the wave or the music including the sound of the wave is caused to flow in the bathroom 9, and the volume of the speaker 32 is changed according to the water level in the bathtub 5.
For example, the volume is increased in the whole body bath state where the water level is high, and the volume is reduced in the half body bath state where the water level is low. Further, the tempo, rhythm, etc. of music are controlled according to the fluctuation of the water level in the bathtub 5. For example, when the water level rises, the tempo is increased or the rhythm is increased, and when the water level is lowered, the tempo is decreased or the rhythm is moderated.

Further, the control means 100 uses the detection information of the pressure of hot and cold water in the bathtub 5 detected by the water pressure detection means 102 (water level sensor 7) as the bathroom information,
It is configured to execute the adjustment control. Further, the control unit 100 is configured to detect the operation detecting unit 103.
The adjustment control is executed by using the detection information of the bather's movement in the bathroom 9 detected by the (water level sensor 7) as the bathroom information. The adjustment of the acoustic characteristics based on the detection information of the pressure of hot water and the detection information of the action of the bather will be described. As the action of the bather in the bathroom 9, the bather manually stirs the hot and cold water in the bathtub 5 to make hot water. If you perform an action that generates a wave on the surface,
The bather's action is detected by the water level sensor 7 as a change in the pressure of the hot water in the bathtub 5, and the sound of the wave or the volume of music from the speaker 32 is adjusted according to the change in the pressure. Specifically, in the case of a large wave, the fluctuation of the pressure detection value increases depending on the magnitude of the wave, so the volume is increased to generate a large wave sound, and in the case of a small wave, the fluctuation of the pressure detection value. Is smaller, the volume is reduced to produce a rippled sound.

Further, the control means 100 adjusts the characteristics of the sound emitted to the outside of the bathroom (kitchen or the like) by the outside-bath acoustic means (the speaker 32 of the kitchen remote controller 4) based on the bathroom information. Is configured. Specifically, as described above, when the bather in the bathroom 9 operates by stirring the hot and cold water in the bathtub 5 by hand, and when the pressure change of the hot and cold water is detected, the speaker 32 of the kitchen remote controller 4 operates. The sound and music of waves adjusted according to the pressure change are emitted. And if the characteristics of the sound to the outside are stable,
It is determined that the sound is emitted from the speaker 32 of the kitchen remote controller 4 when the bather has drowned in the bathtub and has an abnormal state due to convulsions or seizures. Since the situation is different from that in the state, the house owner or the like who hears the sound can know the abnormality occurrence in the bathroom.

Next, the control means 100, based on the bathroom information (the water level and pressure of the hot water in the bathtub 5 and the movement of the bather in the bathtub 5) detected by the water level sensor 7, Adjustment control for adjusting the characteristics of the illumination in the bathroom 9 illuminated by the illumination means 8 will be described. Specifically, it is determined from the water level in the bathtub 5 detected by the water level sensor 7 whether the bather is in the washroom, taking a full body bath, or a half body bath. When not bathing (when the bather is in the washroom), when bathing with a full-body bath, and when bathing with a half-body bath, the brightness in the bathroom is dim. That is, when not bathing, it is necessary to lighten the body because it is washed, and in the half-body bath, it is possible to relax by making it darker. In the whole-body bath, there is a higher risk of an accident during bathing, so it is brighter than the half-body bath. By observing the change in the brightness (illuminance) in the bathroom 9 from outside the bathroom 9, the state of the bather in the bathroom can be indirectly determined.

Further, the control means 100 is configured to adjust the characteristics of the illumination of the outside of the bathroom 9 (the washroom) illuminated by the exterior lighting means 15 based on the bathroom information. . Specifically, as described above, when the bather in the bathroom 9 operates by stirring the hot and cold water in the bathtub 5 by hand, and when the change in the hot and cold water pressure is detected, the illuminance of the outside lighting means 15 of the bathroom is detected. Is adjusted according to the pressure change.
Then, when the illuminance change outside the bathroom (washroom) is stable (for example, the illuminance changes gently),
Although it is determined to be in a normal state, for example, when the bather has drowned in the bathtub, and when an abnormal state occurs due to convulsions or seizures, the illuminance of the exterior lighting means 15 may be different from that in the normal state. Are different from each other (for example, the illuminance changes drastically or does not change at all), so that the housekeeper or the like can know the abnormality occurrence in the bathroom by looking at the illumination state.

The control means 100 detects the water level sensor 7 via the controller 2 when controlling the characteristics of the sound and lighting in the bathroom 9 based on the bathroom information. Is configured to get bathroom information.

Next, based on the change in the water level and the pressure in the bathtub 5 detected by the water level sensor 7, the bathroom 9
A control mode in the case of adjusting the characteristics of the sound and the illumination in the inside will be described. That is, the control means 100 causes the bather to bathe in the bathtub 5 the adjustment content according to the amplitude value of the water level change or the pressure change in the bathtub 5 detected as the bathroom information, as the adjustment control. It is configured to be executed while changing the adjustment ratio with respect to the amplitude value of the water level change or pressure change between when the water is being bathed and when the bath is not being bathed.

First, FIGS. 3 (a) and 3 (b) show the output waveforms of the water level sensor 7 when the bather is not bathing in the bathtub 5 while stirring the hot and cold water in the bathtub 5 by hand. Here, (a) when the stirring operation is small, the amplitude value of the output change of the water level sensor 7 is small, and (b) when the stirring operation is large, the amplitude value of the output change of the water level sensor 7 is large. I understand. Moreover, the output waveform of the water level sensor 7 when the bather bathes in the bathtub 5 is shown in FIG. 3C, and it can be seen that the water level rises with the bathing operation. Furthermore, the output waveform of the water level sensor 7 when the bather is bathing in the bathtub 5 in a resting state is shown in FIG.
FIG. 4B shows an output waveform of the water level sensor 7 when the hot and cold water in the bathtub 5 is greatly stirred by hand while taking a bath in the bathtub.
Shown in. Here, as compared with FIG. 3B, even when the action of stirring the hot and cold water in the bathtub 5 is similarly large, the water level when the bather is bathing in the bathtub 5 is higher than when the bather is not bathing. It can be seen that the amplitude value of the output change of the sensor 7 becomes smaller. Moreover, the output waveform of the water level sensor 7 when the bather leaves the bathtub 5 is shown in FIG. 4C, and it can be seen that the water level drops with the bathing operation.

Therefore, based on the above results, the control means 100
Makes the adjustment ratio for the amplitude value of the water level change or the pressure change when the bather is bathing in the bathtub 5 larger than the adjustment ratio when the bather is not bathing in the bathtub 5. Explaining the adjustment of the acoustic characteristics in the bathroom 9 as an example,
For example, while the waving sound is always flown into the bathroom 9, the volume of the waving sound is relatively low when the bath is not bathing even when the amplitude value of the water level change or the pressure change is large, and when the bath is bathing, the water level change or the pressure is changed. Even if the amplitude value of the change is small, the volume of the rippling sound is adjusted to be relatively large.

Further, the control means 100 generates a shell sound corresponding to each of the bathing operation and the bathing operation so that it can be understood that each operation is performed. In this case, the bathing operation is performed. By making the pronunciation time of the shell sound at time longer than the pronunciation time of the bathing operation, it is possible to easily distinguish between the bathing operation and the bathing operation. Furthermore, the control means 1
When 00, the low-pitched synthesizer sound is repeatedly generated as the basic tone during bathing, and the amplitude value of the change in the water level or the pressure change in the bathtub 5 exceeds the set value due to the stirring operation of the bather, for example. When
An amplitude trigger (to be described later) is issued), and a synthesizer sound of a high-pitch melody and a piano sound of a phrase unit are generated for a predetermined time. Here, each amplitude trigger changes the occurrence probability (random number) of the mid-high-tone melody of the synthesizer sound, and a phrase to be played with a piano sound is selected.

FIG. 5 shows a flow of adjustment control of acoustic characteristics based on a change in water level and a change in pressure in the bathtub 5.
First, after the output of the water level sensor 7 is AD-converted into digital data, noise processing is performed and converted into water level data (steps # 1 and # 2). Incidentally, the waveforms shown in FIGS. 3 and 4 show the output of the water level sensor 7 before the noise processing.
Next, a process of determining whether or not the user is taking a bath based on the water level data is performed (step # 3). Specifically, based on the average water level during non-bathing (see FIG. 3 (a) (b)), a threshold higher than the average water level during non-bathing is set, and the water level higher than this threshold is set. If it continues for a certain period of time, it is determined to be bathing. On the other hand, the amplitude value of the water level change or the pressure change is extracted from the water level data (step # 4). Specifically, as shown in FIG. 6, a window having a predetermined time width is set, and the difference between the maximum value and the minimum value of the water level data within this time window is obtained as an amplitude value. Incidentally, the time width of the window corresponds to the fluctuation cycle of the water level sensor output, and is 1.5 sec in this example. Then, the time window is moved as time passes. Further, it is determined whether or not the extracted amplitude value exceeds the threshold value (step # 5). Specifically, a predetermined time width of the extracted amplitude value (for example,
(800 msec) maximum amplitude value in a window is calculated, and when this maximum amplitude value exceeds the threshold value and it is determined in the bathing / non-bathing determination process that bathing is in progress, an amplitude trigger signal is output. To do. Then, based on the bathing state signal determined by the bathing / non-bathing determination processing, acoustic adjustment (occurrence of shell noise) corresponding to the bathing operation and the bathing operation is performed (step # 6), and the amplitude trigger signal is generated. Sound adjustment (generation of synthesizer sound and piano sound) corresponding to the above (step # 7), and sound adjustment (volume adjustment of rippling sound) according to the amplitude value of the water level change and pressure change in the bathtub 5 (Step # 8).

Second Embodiment Next, a second embodiment of the bathroom environmental information generating apparatus according to the present invention will be described. In the second embodiment, as shown in FIG. 3, a biological information detecting means 104 for detecting biological information of a bather is provided, and the control means 100 causes the biological information detecting means 10 to operate.
Similar to the first embodiment except that the adjustment control is executed by using the bather's biometric information detected in 4 (specifically, the bather's electrocardiogram information) as the bathroom information. It is configured. Hereinafter, differences from the first embodiment will be described. In addition, specifically, the control means 100 uses the biological information together with bathroom information (specifically, the water level in the bathtub 5) detected by the hot and cold water state detection means 101 (water level sensor 7). Then, the adjustment control is executed. The biometric information detection means 104 is composed of a bathtub electrocardiograph 20 which detects electrocardiographic information generated from electric signals appearing on a plurality of electrocardiographic electrodes 10 installed on the inner wall surface of the bathtub 5 as the biometric information.

As shown in FIGS. 4 and 5, the bathtub electrocardiograph 2 is used.
Reference numeral 0 denotes the plurality of electrocardiogram electrodes 10, electrocardiogram signal generation means 11 for generating and processing electrocardiogram signals from electric signals appearing on the plurality of electrocardiogram electrodes 10, and electrocardiogram signal generation means 11
And a signal processing means 12 for performing a predetermined signal processing on the electrocardiogram signal generated in. Then, the electrocardiogram information obtained by the bathtub electrocardiogram 20 is input to the control unit 30 of the bath remote controller 3.

The plurality of ECG electrodes 10 are four electrodes 10a.
-10d, and the electrodes 10a to 10d are separately installed at predetermined positions on the inner wall surface of the bath 5 to be immersed in hot water. Specifically, the first electrode 10a is located near the outside of the base of the bather's right arm, the second electrode 10b is located near the outside of the base of the bather's left arm, and the third electrode 10c is located at the base of the bather's left foot. The fourth electrode 10d is installed at a position close to the outside and at a position close to the outside of the right foot base of the bather. Then, the surface potential of each corresponding portion of the bather is induced in each of the electrodes 10a to 10d by the conductive path formed through the hot and cold water in the bath.

Basically, the electrocardiogram signal generating means 11 is
Six types in the standard 12-lead method represented by the following formula, which are configured to include a plurality of differential amplifiers that combine the electric signals induced in the electrodes 10a to 10d and obtain a difference signal between the combined signals. ECG signals of the standard limb induction (V1, V2, V3, aV R, aV L, aV F) to produce a. In the formula, V _R , V _L , and V _F are respectively the first electrode 1
0a, the second electrode 10b, and the third electrode 10c are induced potentials.

[0058]

[Number 1] _{V1 = V L -V R V2 =} V F -V R V3 = V F -V L aV R = V R -0.5 (V L + V F) aV L = V L -0.5 ( _{V R + V F) aV F} = V F -0.5 (V R + V L)

The signal processing means 12 responds to the electrocardiogram signal generated by the electrocardiogram signal generating means 11 by applying a low frequency generated due to the movement of hot water in the bathtub 5 or the movement of the body of the bather. The baseline sway component is removed, and further the P wave, Q wave, R wave, S wave, T
A specific signal wave is extracted from characteristic signal components such as waves and QRS groups, and electrocardiographic information included in the specific signal wave is further extracted and output. Specifically, as shown in FIG. 6, the R wave is extracted, the time phase of its occurrence is detected, and the heart rate and its time fluctuation are detected from the interval of occurrence.

Then, the control means 100 increases the average value of the sound volume in the state of the whole body bath having a high water level detected by the water level sensor 7, and the average value of the volume in the state of the half body bath having a low water level. While decreasing the value, the speaker 32 is connected to the bathroom 9 in accordance with the heart rate detected by the signal processing means 12, specifically at the timing of the R wave.
Adjusts the strength of the sound of waves and the volume of music emitted inside. For example, the volume is increased during the R wave generation time phase, and is decreased when the R wave generation time phase is distant from the R wave generation time phase. This allows
Depending on the relaxing effect of the bather by adjusting the volume level according to the water level, and listening to the CD containing the heart sounds of the fetus as music for relaxing the infant, for example, depending on the bather's heartbeat. By combining with the relaxing effect by changing the tone of the music played in the bathroom, a more appropriate relaxing effect can be obtained.

Further, the control means 100 adjusts the characteristics (illuminance) of the illumination in the bathroom 9 illuminated by the illumination means 8 based on the water level information and the electrocardiogram information. Specifically, the average value of the illuminance is increased in the whole body bath state where the water level is high, and the average value of the illuminance is reduced in the half body bath state where the water level is low. 8 is operated by blinking, or
Brightness is adjusted so that it becomes bright when the R wave is generated and darkened when the R wave is generated. As a result, as in the case of adjusting the volume, a relaxing effect by adjusting the brightness according to the water level bathed by the bather,
By combining with the relaxing effect by changing the brightness according to the bather's heartbeat, a more appropriate relaxing effect can be obtained.

Specifically, the temperature of the hot water in the bathtub is measured by a temperature sensor, or the set temperature set by the bath remote controller 3 is set as the hot water temperature. Then, the control means 100 uses information on the temperature of the hot water in the bathtub measured by the temperature sensor or the set temperature set by the bath remote controller 3 as the bath information.

In the first embodiment, the motion detecting means 10
The control means 1 detects the operation of stirring the hot and cold water in the bathtub 5 by hand to generate waves on the surface of the hot water as the operation of the bather.
00 is configured to adjust and control the sound of waves and the like according to the movement of the bather. In addition to this, the movement detecting means 103
However, as a bather's action, when the bather taps the surface of the bath with a hand, the action is detected by the water level sensor 7, and the control means 100 matches the action of tapping the bath. The sound may be generated from the speaker 32. In this case, the location of the water level sensor may be attached to the vicinity of the handrail of the bathtub 5 instead of the hot water supply passage 6 to the bathtub 5. When tapping the surface of the molten metal, something like a drumstick may be used instead of the hand.
In this case, the bee is provided with a submersion detection unit to detect the submergence, or the bee is provided with a weak current transmission unit to detect the pattern of the current flowing in the bath from the current transmission unit. The submersion of the drumstick may be detected, and the music from the speaker 32 may be adjusted and controlled by the submersion detection information.

In this case, the battery in the bucket,
A speaker may be built in and music may be generated from a pail or the like. Further, the motion detecting means 103 may be configured to detect the motion of the bather based on the detection information of the sensor incorporated in the shower head that the bather holds and operates when taking a shower. For example,
As the sensor, a hot water temperature sensor, a water amount sensor, an inclination sensor, or the like is used. Then, the music played in the bathroom is adjusted and controlled by the temperature of the shower, the amount of water, the inclination of the head, etc. detected by these sensors.

Since it is judged that the person is using the shower or washing the body with hot water drawn from the bathtub by hand, the music is played by the bath remote controller 3 or the kitchen remote controller 4. In this case, depending on the value of the water amount detected by the water flow sensor (whether the water amount is large or small),
You may control the content of music, such as a kind, a volume, and a tempo. As a result, there is an effect that the bather can enjoy listening to the music while taking a shower, and when the music continues to flow for an abnormally long time, the bather may fall down during the shower, for example. The effect is that the family can notice the situation.

Further, the action detecting means 103 detects the position of the baton when the bather holds something like a baton in his hand and swings it around with a magnetic sensor or the like,
The change in the position of the baton may be detected as the movement of the bather. In this form, since the music changes with the movement of the baton, a relaxing effect that the bather feels like having become a conductor can be obtained.

However, in addition to this, the outside-bathroom lighting means 15 may be changed during bathing. It may be configured with a lighting lamp provided in a bedroom or living room where there is a high possibility that there is a family.

In the third embodiment, the motion detecting means 10
