4. Control the alarms 62 and 72 of the remote controllers 60 and 70, and the display units 63 and 73.

In the above configuration, first, hot water supply control not related to the present invention will be briefly described. When the user opens the hot water tap 14, the flow sensor Qa detects a water flow of a predetermined amount or more. The control unit 50 operates the ignition mechanism and the fan in response to the detection of the water flow. At the same time, the on-off valve 4 is opened, and gas is supplied to the gas burner 1 to start combustion. Water from the water supply pipe 12 receives combustion heat in the process of passing through the heat receiving pipe 11 to become hot water, and is discharged from the hot water tap 14 through the hot water supply pipe 13.

Next, the control relating to the bathing management of the present invention executed by the control unit 50 will be described. As shown in FIG. 2, it is determined whether or not the automatic operation switch 61 or the beauty switch 65 is turned on (steps 101 and 102), and waits until it is turned on. When the automatic operation switch 61 is turned on, the automatic operation mode 2
00 (normal control mode), and when the beauty switch 65 is turned on, the beauty and health promotion mode 300
Execute

In the above automatic operation mode, pouring is performed first. That is, the gas burner 1 is burned in the same manner as in hot water supply, and the pouring valve 31 is opened to supply hot water from the hot water supply pipe 10 to the bathtub 6 via the pouring pipe 30 and the additional heating pipe 20. At this time, the proportional valve 5 is controlled based on the feedback signal of the temperature detected by the temperature sensor T _OUT . In the present embodiment, since the hot water that has passed through the temperature sensor T _OUT is of a one-can-two-water-channel type and is reheated, the temperature detected by the temperature sensor T _OUT is obtained by subtracting the temperature rise due to the reheating from the set temperature. Control the combustion to a value. In the above pouring control,
The relationship between the pouring flow rate and the bathtub water level is determined in advance, and the integrated flow rate corresponding to the set water level set by the remote controller is determined from this relationship. If the integrated flow rate of the flow sensor Qa becomes the flow rate corresponding to the set water level, , End pouring. As a result, the bathtub 6 is filled with hot water of the temperature set by the remote controller up to the set water level. After that, automatic heat insulation,
Perform automatic pouring. That is, at a predetermined time interval, the pump 24
And the hot water in the bathtub 6 is supplied to the return pipe 22 and the forward pipe 23.
When the temperature of the bath tub detected by the temperature sensor T _HR is lowered, the gas burner 1 is burned to perform additional heating, and the bath tub temperature is raised to a set temperature (automatic heat retention). . When the bathtub water level detected by the water level sensor 32 falls below the set water level, hot water is poured into the bathtub 6 in the same manner as the above-described pouring (automatic pouring).

Next, the beauty and health promotion mode, which is the most important feature of the present embodiment, will be described. First, roughly speaking, water is poured so that the water level is lower than the set water level, and time management is performed so as to repeat bathing and resting three times, thereby prompting appropriate sweating desired by the user. Thereafter, pouring is performed to the set water level, and automatic heat retention and automatic pouring are performed as in the automatic operation mode. The details will be described below.

First, as shown in FIG. 3, a counter K indicating the number of times of bathing is cleared (step 301). Next, a sweating level is set. That is, every time the beauty switch 65 is turned on (step 303), the level is increased by one step (step 305). When the elapsed time from when the beauty switch 65 is first turned on reaches a predetermined time (for example, about 10 seconds) (step 307), the process proceeds to step 308. Step 30
In 5, the level is also displayed on the display unit 63, so that the user (bather) can operate the beauty switch 65 while watching this display to freely set the desired sweating level. As is clear from the above description,
The beauty switch 65 also plays a role as a level setting means.

Incidentally, in the present embodiment, the sweating level is set to five levels, and the conditions at each level are as follows.

The amount of perspiration increases as the bath temperature increases, as the bathing time increases, and as the break time decreases. Level 1 with the least amount of sweat will be described in detail. In the first bathing, the bath temperature is set to 1.5 ° C lower than the set temperature,
The bathing time and the rest time are 5 minutes. In the second bathing, the bathtub temperature is set to be 1.0 ° C. higher than the first bathing. That is, the temperature is set lower by 0.5 ° C. than the set temperature. In the third bathing, the bath tub temperature is set to be 1.0 ° C. higher than in the second bath. That is, the temperature is increased by 0.5 ° C. from the set temperature. In this way, as the number of times is increased, the amount of perspiration is gradually increased, and the burden on the bather is reduced.

At levels 2 and 3, the amount of perspiration is increased by gradually increasing the bathing time. At levels 4 and 5, the amount of perspiration is increased by gradually shortening the break time. Other conditions for levels 2 to 5 are the same as those for level 1.

In step 308 after the level setting,
Based on the set level, a scheduled bathing time and a rest time for each number of bathings are determined, and a bathtub hot water temperature is determined based on the set temperature. Next, pouring is performed (step 309). However, the pouring temperature is set at 1.5 ° C. lower than the set temperature so as to satisfy the first bathing condition in the beauty and health promotion mode. This pouring is performed by the proportional valve 5 based on the detection signal from the temperature sensor T _OUT provided in the hot water supply pipe 13 as described above.
Is feedback-controlled to maintain the temperature 1.5 ° C. lower than the set temperature. This temperature sensor T
_OUT has a correspondence between the detected temperature and the pouring temperature (bath bath temperature) (as described above, the bath temperature is higher than the detected temperature by the reheating temperature), and also serves as a bath temperature sensor. Carry. Also, the bathtub water level by this pouring is set lower than the set water level by a predetermined water level, for example, 15 cm. The bathtub water level is managed based on the integrated value of the flow rate of the flow sensor Qa or the detection information from the water level sensor 32. Since the bathtub water level is lowered in this way, in the beauty health promotion mode,
Despite promoting sweating, the burden on the heart can be minimized. This is based on the assumption that the set water level set by the remote controller will be about the shoulder level of the bather, and if the predetermined water level is lower than the set water level by, for example, 15 cm,
The water level is lower than the heart position of the bather, and the water level is hardly affected by the water pressure, so that the bath can be performed with less burden on the heart.

When the pouring of step 309 is completed, alarms 62 and 72 of the bathroom remote 60 and the kitchen remote 70 are provided.
To inform that the preparation is completed (step 311). After hearing the alarm, the user enters the bathtub 6 (hereinafter, this is referred to as bathing). The microcomputer waits for this bath while monitoring the water level information of the water level sensor 32. When the water level detected by the water level sensor 32 rises above the threshold value within a predetermined time, it is determined that there is bathing (step 313), and only the alarm 62 of the bathroom remote controller 60 is activated (step 315), and the bathing time is managed. In order to do so, a timer is operated (step 317). The alarm is for notifying the bather that the beauty and health promotion mode is functioning normally.

The microcomputer proceeds to step 317
Is executed, it is determined whether or not the elapsed time measured by the timer, that is, the bathing time has reached the scheduled bathing time (step 319). When it is determined that the bathing time has been reached, the alarm 62 of the bathroom remote controller 60 is activated. Bather in bathtub 6
(Step 321). The bathing scheduled time is determined by the sweating amount level and the number of times of bathing set as described above.

After step 321, a timer is activated to warn of a long bath (step 323; see FIG. 4). Thereafter, it is determined whether or not the time measured by the timer (extended bathing time) has reached a predetermined time (about several minutes) (step 325). If not, the detected water level falls below the threshold within the predetermined time. It is determined whether or not bathing has been performed, that is, whether or not a bath has been taken (step 327). If the measurement time reaches the specified time without taking a bath, the bather may have an abnormality and need to be rescued,
Activate alarm 72 of kitchen remote controller 70 as well as alarm 62 of bathroom remote controller 60 (step 32).
9). This will ensure the safety of the bather. At this time, the display of the abnormality alarm may also be performed on the display units 63 and 73 of the remote controllers 60 and 70. This alarm is preferably executed for a relatively long time. Further, the alarm may be continued until a switch operation or a button operation of the remote controllers 60 and 70 is performed. After the execution of the step 329, the entire control may be ended. However, the bather may return to the step 323 or the step 331 by operating a switch or a button of the bathroom remote controller 60.

If the bather is normal, step 32
Since the person leaves the bathtub 6 after hearing the bathing request alarm at step 1, the affirmative judgment is made in step 327 before the alarm timer times out, and the routine proceeds to step 331, where the counter K is incremented. For example, when the counter K changes from “0” to “1”, it indicates that the first bathing is completed.

Next, it is determined whether or not the counter K has become "3". In other words, it is determined whether the third bathing is completed (step 333). In the case of a negative decision,
The reheating is started (step 335), and a timer is operated for a break time management (step 337). And
Wait until the time measured by the timer (rest time) reaches the scheduled rest time (step 339), and when it reaches, the alarm 62 of the bathroom 60 is activated to notify the end of the rest. Then, the process returns to step 313 to prepare for the next bathing time management and break time management.

The break end alarm indicates that a rest period corresponding to the set level has been taken, and in order to obtain a desired amount of sweating, immediately take a bath after hearing the break end alarm. Is preferred. But,
If the rest time is considered exclusively from the viewpoint of safety such as prevention of hot flashes, the alarm of the end of the rest plays the role of permitting the next bath, so it is up to the user to decide when to take a bath. Is done. The additional firing performed during the break time is for raising the bath tub temperature by, for example, 1 ° C. to prepare for the next bathing. Can be managed with high accuracy. In addition, instead of this additional heating, hot water may be poured to raise the bath water temperature.

When an affirmative determination is made in step 333, pouring is started (step 343), and step 34 similar to steps 337, 339 and 341 is started.
After 5,347 and 349, the process proceeds to normal automatic heat retention and automatic pouring (step 351). In addition, since the pouring for normal bathing (step 343) is performed using the break time after the last bathing (the third time) for promoting beauty and health, the transition to normal bathing is smoothly performed. It can be carried out. The above pouring is for filling the bathtub water level to the set water level. In the present embodiment, since the bath water temperature in the last time is in a state higher than the set temperature, the pouring temperature is set to a temperature slightly lower than the set temperature, and when pouring to the set water level is completed. It is preferable that the bath temperature is set to the set temperature.

It has been confirmed by the present inventor that the bathing method of the present embodiment not only warms the body and promotes metabolism but also consumes energy. That is, in normal bathing, the body temperature returns to the temperature before bathing in about one hour after bathing, whereas in the bathing method of the present invention, it takes about 6 hours, which is considered to be effective for beauty, diet, and the like. A slimming effect can also be expected. In addition, since the water level at the time of bathing in the present application is lowered, the bath becomes a half-body bath, and there is almost no influence of water pressure as compared with the whole body bath, and it is possible to perform bathing that does not burden the heart. Further, when bathing in hot water of, for example, 42 ° C., the blood pressure rises by about 50 from the normal state (for example, 120-80), whereas in the bathing method of the present application, the blood pressure rises by lowering the bathing temperature. However, bathing can be performed slowly and with little change in blood pressure. In addition, even if the pulse rises, the bathing method of the present application can be increased to about twice as much as that of ordinary hot water (42 ° C.) for 10 minutes, while the bathing method of the present application can be about 1.6 times. Bathing can be performed with little change on both the blood pressure and the pulse and with less burden on the body.

In the above embodiment, the bath tub temperature is increased as the number of baths is increased. Instead, or together with this, the bathing time is lengthened or the break time is shortened, so that the amount of perspiration is gradually increased. May be increased. In the above embodiment, as the sweating level increases, the bathing time is lengthened or the break time is shortened. However, instead of or together with these, the bathtub temperature may be raised. . Further, the number of times of bathing may be increased as the sweating level increases. For example, in the case of level 1, the number of times of bathing is set to one, and as the level increases one step, the number of times of bathing is increased, and in the case of level 5, the number of times of bathing is set to five times. In the above embodiment, the measurement of the bathing time, the rest time, and the time for the alarm are performed by the common timer, but may be performed by separate timers. In this case, the plurality of timers are collectively referred to as time counting means. When you repeat bathing (for example, 2
During the rest period (when shifting from the third time to the third time), the temperature of the bath water may be lowered by opening the pouring valve 31 and injecting water without burning the gas burner 1. In the above embodiment, the last (third) break time management may be omitted.

In the above embodiment, the bath tub temperature for each number of baths is determined based on the set temperature set by the user, and the expected bathing time is determined according to the set level and the number of baths.
That is, the scheduled bathing time is determined independently of the bathtub temperature. However, the scheduled bathing time may be determined in consideration of that the higher the temperature of the bath tub, the larger the amount of perspiration per unit time, and the lower the temperature of the bath tub, the smaller the amount of perspiration per unit time. That is, the higher the bathtub temperature, the shorter the bathing scheduled time, and the lower the bathtub temperature, the longer the bathing scheduled time. As a result, the correspondence between the set level and the amount of perspiration becomes more accurate.

In the above embodiment, the bath tub temperature is changed according to the set temperature. However, the bath tub temperature may be a fixed value, or may be changed according to the set level or the number of times of bathing irrespective of the set temperature. Is also good. In addition, the bathing schedule time may be set higher in the middle period than in the first and second periods. An example is shown below.

The water level by pouring may be automatically changed after bathing. This calculates the bather's volume, that is, weight, based on the initial bathtub water level and the rise in water level when bathing, and estimates the height H of the bather from the following height and weight table published by the Ministry of Health and Welfare.

[Table 1] Then, the height H / 4 of the lower end of the heart from the seat surface when properly sitting is roughly calculated. Further, the lower end of the heart (H / 4) sinΘ when the bather is leaning on the backrest in the bathtub and relaxing is calculated from the angle of the backrest of the bathtub. The backrest angle Θ is calculated from the relationship between the pouring flow rate and the bathtub water level obtained in advance in the automatic sequence. By the way, the Japanese-style bus is 96 °, the Western-style bus 63 °, and the Japanese-Western mixed bus 74 °. Then, the calculated lower end of the heart (H / 4) sinｓ is compared with the bathtub water level in the bathing state. If the bathtub water level is higher than the bathtub, the bath is poured. Do. Also, instead of changing the bathtub water level, if the heart lower end position is higher than the bathtub water level, the bathing scheduled time is not changed, and if the heart lower end position is lower than the bathtub water level, the bathing expected time is shortened. Good. Further, when the lower end position of the heart is higher than the bathtub water level, pouring may be performed, and when the lower end position of the heart is lower than the bathtub water level, the bathing scheduled time may be shortened.

A specific example of changing the bathing scheduled time according to the rise in the bathtub water level will be described. Remote control setting water level is 42
cm, initial water level 27 cm (42-15)
It is assumed that the water level has risen to 33 cm as a result of taking a bath and waiting for the first bathing. The body weight of the bather is estimated to be 60 kg from the water level increase data, the initial water level data, and the data indicating the relationship between the water level and the water amount obtained in advance during automatic hot water filling. At the weight of 60 kg, the lower limit of the height H is 147 cm for a fat woman who is 60 years old and the upper limit of the height H is 173 cm for a 20 year old man who is slightly lean from the data released by the Ministry of Health and Welfare. Therefore, the height of the lower end of the heart of the bather is (H / 4) sin {
= 74 °), the lower limit is 35.3 cm and the upper limit is 41.6 cm. Actually, the microcomputer calculates the lower limit of the height of the lower end of the heart based on the weight. As described above, since the calculated lower limit of the lower end of the heart, 35.3 cm, is higher than the water level of 33 cm in the bathing state, the alarm of the bathtub remote controller sounds after the predetermined bathing scheduled time has elapsed. When the water level set on the remote controller is 48 cm, the initial water level is 33 cm (48-1).
After the bath is filled with water to 5), the first bathing is waited, and as a result of bathing, the water level rises to 40 cm. From the water level rise data, the weight of the bather is estimated to be 60 kg, and the lower limit of the lower end of the heart, 35.3 cm, is calculated. Since this lower limit value is lower than the water level in the bathing state of 40 cm, the predetermined bathing scheduled time is shortened. For example, change 5 minutes to 4 minutes. Then, the alarm of the bathtub remote control is sounded after the shortened scheduled bathing time has elapsed.

Next, another embodiment of the present invention will be described. These embodiments are for making the cosmetic health promotion mode of the above-described first embodiment more precise (that is, more precisely controlling the amount of sweating) or more secure.
In the second embodiment, the control shown in FIG. 5 is incorporated between steps 313 and 315 in FIG. More specifically, after step 313 in FIG. 3, the volume (weight) of the bather is calculated from the water level rise at the time of bathing and the initial water level information (step 314a). Next, based on the obtained bather volume,
At least one of scheduled bathing time, scheduled resting time, and bath water temperature is adjusted (determined). That is, the scheduled bathing time, the scheduled resting time, and the bathtub temperature are determined for each number of bathings by the above-described level setting (step 308).
At least one of bathing time, bathtub temperature,
Alternatively, both are adjusted such that the larger the bather's volume, the larger the amount of perspiration, and the smaller the volume, the smaller the amount of perspiration. A person with a large volume promotes a large amount of sweating for beauty and health, and a person with a small volume suppresses sweating and reduces the burden on the body. Also, consider that the larger the volume, the harder it is to warm and harder to cool. Specifically, in the case of a person with a large volume, the bathing scheduled time is lengthened, or the temperature of the bath tub is raised by additional heating or high-temperature pouring, and in the case of a person with a small volume, the bath is reversed. Shorten the scheduled time. As described above, the larger the person, the longer the expected bathing time or the temperature of the bath tub will increase sweating, but instead, the longer the scheduled resting time and wait for the elevated body temperature to return Prevents strain on the body. In addition,
Instead of performing the level setting in steps 303, 305, and 307 in FIG. 3, the scheduled bathing time, the scheduled resting time, and the bathtub temperature may be determined based on the information of only the bather volume as described above.

Next, a third embodiment will be described.
In this embodiment, the bathroom remote control 60 is provided with a room temperature sensor 69 for detecting the temperature in the bathroom (indicated by an imaginary line in FIG. 1). Then, step 335 of FIG.
Step 336 of FIG. 6 is incorporated during 337 and between steps 343 and 345. That is, the room temperature sensor 69
The scheduled resting time is adjusted (determined) based on the bathroom temperature detected in (1). That is, when the bathroom temperature is high,
Since it is considered that the body temperature does not drop easily and the amount of sweating in the next bathing increases (the burden on the body is increased), the scheduled resting time is extended and the body temperature is sufficiently cooled. If the bathroom temperature is low, the body temperature is expected to decrease in a short time, so the scheduled break time is shortened. This also has the effect of preventing hot flashes when the bathroom temperature is high and preventing the skin from feeling chilly when the bathroom temperature is low. It should be noted that the bathing scheduled time and the bathtub temperature may be adjusted based on the bathroom temperature information. Further, the scheduled bathing time, the scheduled resting time, and the bathtub temperature may be determined in conjunction with the single information of the bathroom temperature or other information (set level, set temperature, volume, etc.) described above.

Next, a fourth embodiment will be described. In this embodiment, it is considered that the body temperature cooling effect of the bather differs depending on how the break time is spent. For example, the body does not cool down too much when the body is washed, the hair is washed, and the body is warmed by a shower or the like.
On the other hand, if you take a quiet break without pouring hot water on your body, your body will cool down. Therefore, when the body is not cold, the bathing time is shortened to prevent "hot flashes". This is because bathing when the body is not cold increases the amount of perspiration and puts a burden on the body.

More specifically, steps 317 and 31 in FIG.
The control shown in FIG. After bathing, were allowed to start bathing timer, a pump 24 is driven to circulate the hot water bath 6 (step 318a), bath water temperature detected by the temperature sensor T _HR threshold (0.5 ° C) or higher It is determined whether the vehicle is descending (step 318b).
Here, when an affirmative judgment is made, a break is taken firmly, reheating is performed, and the bathtub hot water temperature is maintained at the bathtub hot water temperature previously determined as described above (step 318c).
When a negative determination is made in step 318b, it is determined that the user has been warming up during the break time, and the expected bathing time is reduced to prevent “hot flashes” (step 318).
d). In addition, the decrease in body temperature during the rest period
The threshold value may be changed on the basis of the temperature, since the temperature varies depending on the bathroom temperature.

The detection of the bathtub hot water temperature and the determination of "whether or not the bathtub hot water temperature has dropped to a threshold value or more" in FIG.
Perform after minutes. Due to the effect of body temperature, the bath temperature is set at a threshold of 0.
This is because it takes about this time to lower the temperature by 5 ° C. or more. However, from the temperature gradient after bathing, it may be determined whether or not a break is sufficiently taken. For example, the driving of the pump 24 is started immediately after re-bathing, and after the elapse of 30 seconds, the temperature of the bathtub is detected while the driving of the pump 24 is continued for 30 seconds. The amount of decrease in hot water temperature is predicted, and thereafter, the same determination as in step 318b is performed, or "whether a sufficient rest was taken" is determined directly from this temperature gradient. When judging based on the bathtub temperature after a lapse of 2 to 3 minutes from re-bathing, even if it turns out that "breaks are not taken enough"
Since two to three minutes have passed since the re-bathing, the only reason is to shorten the scheduled bathing time, sound an alarm, and prompt bathing. However, when the determination is made based on the temperature gradient as described above, since the determination can be made in a short time from re-bathing, the gas burner is determined when it is determined that “the rest is not sufficiently taken”, that is, one minute after re-bathing. By opening the injection valve 31 without burning in step 1, water injection into the bathtub can be executed, the temperature of the bathtub hot water can be reduced, and "hot flashing" can be prevented. In this case, since bathing is performed while the bathtub temperature is high for the first minute, it is desirable to lower the bathtub temperature by pouring water and shorten the bathing scheduled time (for example, 4 minutes).

All the controls shown in FIGS. 5 to 7 may be incorporated in the control flows of FIGS. 3 and 4. As is clear from the above description, the determination of the bathing scheduled time, the scheduled resting time, and the bathtub temperature may be determined based on a single piece of information described above, or may be determined based on a plurality of pieces of information. Is also good.

In the fifth embodiment, bathing is managed not by time but by the amount of perspiration. Specifically, step 308 in FIG.
Then, "determination of bathing scheduled time" is changed to "determination of the amount of perspiration". Step 319 is omitted. Then, the control of FIG. 8 is incorporated between steps 317 and 321. More specifically, the amount of perspiration is calculated based on the bathing time and the bath water temperature (3.
20a), it is determined whether or not the amount of perspiration has reached the amount of perspiration determined as described above (set value of amount of perspiration) (step 320b), and the process is repeated until the amount of perspiration is reached. When the amount of perspiration reaches the set value, the process proceeds to step 321 in FIG.

In the fifth embodiment, the temperature of the bath tub is detected by driving the pump 24 during bathing and detecting the temperature by the temperature sensor _THR . Alternatively, the temperature of the bathtub in the first bathing is taken as the temperature detected by the temperature sensor T _OUT ,
It may be a temperature detected by the temperature sensor T _HR or subsequent fired end in the bath hot water breaks in the second bath. Also in the fifth embodiment, step 30 in FIG.
The level setting of 3, 305, 307 may be omitted. Further, the control of FIG. 8 may be combined with the control of the embodiment of FIGS. However, step 314b in FIG.
In step 318d, the “scheduled bathing time” is replaced with the “sweating amount setting value”.

In all of the above-described embodiments, instead of obtaining the bathing and bathing signals with the water level sensor, the signals may be obtained by operating the switches or buttons of the bathroom remote controller. In the embodiment of FIG. 5, instead of using the volume calculated from the water level sensor, information on the weight and volume input by operation with the bathroom remote control may be used. By operating the bathroom remote control, the set level of the amount of perspiration may be switched during execution of the beauty and health promotion mode. The beauty and health promotion mode may be canceled on the way by operating the bathroom remote control. In this case, the hot water is immediately poured to the set water level, and the operation shifts to automatic warming and automatic pouring. Also, before the bathing time reaches the scheduled bathing time or before the calculated amount of perspiration reaches the set amount of perspiration, in other words, before the bathing request alarm is issued, if there is bathing, the beauty and health promotion mode is also set. As in the above, it is also possible to immediately pour water to the set water level and shift to automatic warming and automatic pouring as described above.
