Thus, the bather releases the hot water (or water) whose temperature has been adjusted by operating the mixing faucet 30 from the faucet 31 or the shower head 32, and uses the hot water (or water) for washing the body, washing the face and washing the hair on the washing place 3. be able to.

The side wall on one side of the bathtub 2 is provided with the hot water supply port.
A control panel 4 is fixedly mounted at a position above 20. This control panel 4
Has a built-in hot water supply control unit for controlling a water heater (not shown) arranged outside the bathroom 1, and various control conditions such as a hot water temperature and a hot water amount to the hot water inlet 20, a hot water temperature to the mixing faucet 30, and the like. And a built-in warming degree calculating unit 5 (see FIG. 4) for calculating a warming degree described later,
It is configured to display the calculated degree of warming.

FIG. 2 is a plan view showing a configuration example of an operation surface of the control panel 4 facing a bather in the bathtub 2. As shown in the figure, on one side half of the operation surface of the control panel 4, a driving operation unit 40 for setting a hot water supply temperature and a hot water supply amount and operating a water heater outside the bathroom 1 is provided. An operation display unit 41 for displaying the operation content of the unit 40 is provided. Driving operation unit 40
Is given to a hot water supply control unit (not shown) for controlling the operation of the water heater, and the hot water supply control unit performs an operation of controlling the operation of the water heater outside the bathroom 1.

The operation control operation by the hot water supply control section is as follows: "hot water operation" in which hot water of a set temperature and amount is supplied to the hot water supply port 20 and the bathtub 2 is filled, and hot water is supplied to the hot water supply port 20. The operation has been widely performed in the past, such as a "driving operation" in which the remaining hot water in the bathtub 2 is mixed with the remaining hot water to attain an appropriate temperature, and a "hot water supply operation" in which hot water of a predetermined temperature is supplied when the mixing faucet 30 is operated. Description is omitted.

The other half of the operation surface of the control panel 4 is provided with an input operation unit 42 for inputting a condition for calculating the degree of warming described below, and a condition set by operating the input operation unit 42. And a warming degree display section 43 for displaying a warming degree calculated as follows. The calculation of the warming degree is performed by a warming degree calculating section 5 (see FIG. 4) built in the control panel 4, and the warming degree display section 43 displays the warming degree by percentage display, for example, as shown in FIG. It is made to be done.

The degree of warming is an index for giving a bather who is taking a bath in the bathtub 2 an objective criterion for determining whether or not the bathing state is appropriate. The bather senses the degree of warming during bathing by his / her own surface temperature (skin temperature), but the suitability of the degree of warming is determined by the deeper temperature of the bather who rises later with respect to the body surface temperature during bathing. It should be determined and the core temperature tends to keep rising even after bathing. Therefore, the warming degree is defined as a value indicating the degree of increase in the deep part temperature after a lapse of a predetermined time (for example, 10 minutes) from bathing.

The inventor of the present application has changed various bathing conditions such as hot water temperature and room temperature for many subjects having various physical conditions such as physique and age in order to obtain the above-mentioned calculation criteria of the degree of warming. A bathing experiment was conducted in which the subject's body temperature (deep temperature), heart rate and blood pressure were changed over time during and after bathing.

FIG. 3 is a diagram showing general changes in body temperature, heart rate and blood pressure obtained by this bathing experiment. The blood pressure shown in the upper part of the figure keeps a substantially constant value with appropriate fluctuation until a predetermined time elapses from the start of bathing,
Thereafter, a variation mode in which the temperature continuously decreases is shown. Further, the heart rate shown in the center of the figure shows a change mode in which the heart rate keeps a substantially constant value until a predetermined time elapses from the start of bathing, starts increasing almost at the same time as the decrease in blood pressure, and then increases continuously. on the other hand,
The body temperature (deep temperature) shown in the lower part of the figure shows a change mode in which the temperature temporarily decreases after the start of bathing and then gradually increases. Such a change mode is common regardless of the physical condition and the bathing condition, and the difference between the physical condition and the bathing condition is determined at the start of the change (decrease in blood pressure, increase in heart rate and increase in body temperature). Appear as differences.

From the results of the above bathing experiment, the body temperature of the bather as the degree of warming rises with the lapse of bathing time, but the blood pressure decreases, the heart rate increases, and the physical strength of the bather increases. It can be seen that the burden on the organization increases. Referring to the experimental results in more detail, the decrease in blood pressure and the increase in heart rate have occurred slightly after the time of conversion to the increase in body temperature, and the present inventor has found that the bathing state in which the optimal degree of warming is obtained is: After the start of the rise in body temperature, it was considered that the blood pressure indicating physical stress did not excessively decrease and the heart rate did not excessively increase, and the decrease in blood pressure from the beginning of bathing was 10% The time point was considered to be 100% warming.

In the above-described bathing experiment, the body temperature (deep temperature) after bathing of the subject who took a bath at the time when the blood pressure dropped by 10% was traced, and as a result, as shown by a broken line in FIG. Body temperature continues to rise after bathing, and after bathing 10
After a minute, the body temperature is on average 0.44 ° C lower than before bathing
It was found to rise. This increase in body temperature can be said to be a sufficient degree of warming.

In addition, bathing time when the degree of warming becomes 100%,
That is, the bathing time at which the decrease in blood pressure becomes 10% greatly varies depending on the temperature of the hot water inside the bathtub among the above bathing conditions, and also the room temperature in the bathroom, the bathing condition (half-body bath or whole body bath), bathing It has been found that it changes under the influence of other bathing conditions such as the initial state (for example, skin temperature) of the person, and further, under the influence of the physical size of the physical condition.

According to the results of such bathing experiments, in the present invention, the rate of change in the degree of warming with the lapse of bathing time is calculated as follows:
It is predetermined under a plurality of hot water temperature conditions so that the cumulative value at the time when the blood pressure decrease amount becomes 10% becomes 100%, and in the warming degree calculating unit 5, the bather takes a bath in the bathtub 2. The subsequent elapsed time is multiplied by the rate of change, and the results are sequentially accumulated to obtain a reference warming degree. The warming degree is calculated by a procedure of correcting the result according to bathing conditions and body conditions affecting the warming degree. I do.

FIG. 4 is a block diagram showing the structure of the warming degree calculating section 5. The warming degree calculating unit 5 includes a CPU 50, an RO
A CPU 50 that includes an M51, a RAM 52, and an input / output interface 53, and calculates a degree of warming.
The calculation condition of the degree of warming set by the operation of the input operation unit 42 and the detection result of the bathing state detected by the hot water temperature sensor 6, the bathing sensor 7, the room temperature sensor 8, and the hot water sensor 9, respectively, It is provided via an input / output interface 53. In addition, the warming degree calculation part 5 can be comprised in the control panel 4 integrally with the said hot-water supply control part.

FIG. 1 shows a hot water temperature sensor 6, a bath sensor 7,
The arrangement positions of the room temperature sensor 8 and the hot water sensor 9 are shown. The hot water temperature sensor 6 detects the temperature of hot water inside the bathtub 2 and can be constituted by a temperature sensor installed at an appropriate position in the bathtub 2. The bathing sensor 7 detects whether or not a bather is present in the bathtub 2. For example, the bathing sensor 7 can be configured by installing a sensor for detecting a biological signal of the bather at an appropriate position in the bathtub 2. .

The room temperature sensor 8 detects the room temperature inside the bathroom 1 and can be constituted by a temperature sensor installed at an appropriate position inside the bathroom 1. Note that the room temperature inside the bathroom 1 has a large difference depending on its position, such as the distance to the bathtub 2 and the distance to the side wall facing the outside air.
It is desirable to dispose a plurality of temperature sensors at different positions in the bathroom 1 and set the average value of the detected temperatures to room temperature.

The hot water level sensor 9 detects the amount (hot water level) of hot water stored in the bathtub 2. For example, a pressure sensor is provided on the bottom surface of the bathtub 2, and the hot water level sensor 9 responds to the level of the hot water level. The amount of hot water can be detected based on the output of the pressure sensor that changes. In addition, when a bather takes a bath in the bathtub 2, the level of the hot water in the bathtub 2 suddenly increases, so that the hot water level sensor 9 can also be used as the bathing sensor 7.

The ROM 51 of the warming degree calculating section 5 stores a change rate of the warming degree obtained as a result of the bathing experiment, a correction coefficient according to the bathing condition and physical condition of the bather, and a calculating procedure of the warming degree. It is memorized. In the CPU 50, the degree of warming is calculated using the rate of change and the correction coefficient of the degree of warming stored in the ROM 51, in accordance with the calculation procedure also stored in the ROM 51, and the calculation result is output via the input / output interface 53. It is output to the degree display unit 43 and displayed. The RAM 52 is used for storing an appearance value during calculation, such as storing a calculation history.

As described above, the rate of change in the degree of warming is set so as to become 100% when the blood pressure of the bather is 10% lower than the normal value before bathing.
M51 shows the rate of change when a bather of a standard physique, whose initial state before bathing is in a heat neutral state, bathes in a whole body bath at a predetermined room temperature (for example, 25 ° C.). It is stored as a reference table for each 1 ° C. in the hot water temperature range (38 ° C. to 42 ° C.). The rate of change is 100
% May be set to a constant value until the degree of warming is reached. However, in order to correspond to a change in body temperature during actual bathing as shown in FIG. It is desirable to set to increase.

The correction coefficient is set in advance for each of the room temperature in the bathroom, the bathing state, the initial state of the bather, and the physique of the bather, which affect the degree of warming.
The OM 51 stores a reference table for each 1 ° C. within the hot water temperature range.

The correction coefficient based on the room temperature is determined so as to increase or decrease the reference warming degree calculated for the case of the room temperature of 25 ° C. in accordance with the actual room temperature of the bathroom 1. This correction coefficient is selected according to the room temperature in the bathroom 1 detected by the room temperature sensor 7.

The correction coefficient according to the bathing state is determined so that the reference warming degree calculated for the whole body bath is corrected for weight reduction in the case of a half body bath. This correction coefficient is selected according to whether or not a half-body bath switch 42a arranged in the input operation unit 42 is operated in order to operate in a half-body bath. When the half-body bath switch 42a is not operated or the half-body bath switch 42a is not provided, it is determined whether the bath is a whole-body bath or a half-body bath based on the difference in the amount of hot water detected before and after bathing by the hot water sensor 9. The correction coefficient may be selected based on the result of the determination.

The correction coefficient according to the initial state of the bather is obtained by subtracting the reference warming degree calculated for the bather in the neutral temperature state from the temperature when the body is completely cold, such as a bath immediately after going out. It is determined to correct. The correction coefficient is selected in accordance with the operation state of the cooling degree switch 42b disposed on the input operation unit 42 so that the bather can report the cooling degree of his / her body. If the chill switch 42b is not operated or the chill switch 42b is not provided, the initial state of the bather is determined based on the difference between the detected values of the hot water temperature before and after bathing by the hot water temperature sensor 6, The correction coefficient may be selected according to the determination result.

Further, the correction coefficient based on the physique is set so as to increase or decrease the reference warming degree calculated for a bather of a standard physique according to the size of the actual physique of the bather. The correction coefficient is a physique switch arranged on the input operation unit 42 so that a bather can report the size of his or her physique.
It is selected according to the operation state of 42c. Physique switch 42c
Is not performed, or when the physique switch 42c is not provided, the size of the physique of the bather is determined based on the difference between the detected values of the hot water temperature before and after bathing by the hot water sensor 9, and a correction coefficient is determined based on the determination result. May be selected.

FIG. 5 is a flowchart showing a procedure for calculating the degree of warming in the degree of warming calculating section 5. The warming degree calculating section 5 starts operating in response to an ON operation of a power switch included in the driving operation section 40, first takes in the output of the bathing sensor 7 at a predetermined sampling cycle, and determines whether or not the user is bathing. It is determined whether or not bathing has been performed in the bathtub 2 without performing the following operations (step 1).

When it is determined that the user is taking a bath, the warming degree calculating section 5 determines the detection results of the hot water temperature sensor 6, the room temperature sensor 8 and the hot water quantity sensor 9 and the operation state of the input operation section 42 at a predetermined sampling cycle. (= Δt), the rate of change ΔT in the degree of warming is selected based on the detected value of the hot water temperature sensor 6 (step 2), and the detected values of the hot water temperature sensor 6, the room temperature sensor 8 and the hot water amount sensor 9 are also input. selection said correction coefficient based on the operation state of the operation unit 42, i.e., room temperature, bath conditions, bather initial state, and the correction coefficient _{S 1, S 2, S 3} , S 4 for each of the bather physique (Step 3).

Next, the warming degree calculating section 5 multiplies the selected warming degree change rate ΔT by the sampling period Δt,
A standard warming degree ΔW ₀ (= ΔT × Δt) from the previous sampling time to the current sampling time is calculated (step 4), and the correction coefficients S _1, S ₂ ,
The corrected warming degree ΔW (= ΔW ₀ × S ₁₎ is multiplied by S ₃ and S _4.
× S ₂ × S ₃ × S ₄ ) is calculated (step 5).

Finally, the warming degree calculating section 5 adds the calculated corrected warming degree ΔW to the cumulative warming degree W up to the previous sampling time, and calculates the cumulative warming degree W at the current sampling time. Result warming display
Output to 43 and display (step 6). With this,
The current cumulative warming degree W is set to a preset upper limit warming degree W.
_max (step 7), and when W> W _max , a predetermined alarm is displayed (step 8), and it is determined whether or not bathing is continued based on the output of the bathing sensor 7. A determination is made (step 9). If input is being performed, the process returns to step 2 and the above-described operation is repeated. If bathing is not being performed, the display of the warming degree display section 43 is maintained, and the cumulative warming degree W is reset. A series of operations ends.

As described above, the cumulative warming degree W calculated by the warming degree calculating section 5 and displayed on the warming degree display section 43 is:
The rate of change of warming degree ΔT at each sampling point and the warming degree ΔW calculated using the correction coefficients S _1, S ₂ , S ₃ , and S ₄ are sequentially added. Even when a change in the bathing environment such as a change in the room temperature occurs, the bath temperature is a value that correctly indicates the degree of warming of the bather who progresses gradually, more specifically, the predicted value of the degree of warming after bathing.
So the bather. By visually recognizing the display of the warming degree display section 43, it is possible to objectively judge whether the current bathing state is good or not, and it is possible to sufficiently enjoy the bathing effects such as relaxation of tension, recovery from fatigue, etc., and excessive bathing time. The occurrence of health damage due to shortage can be prevented beforehand.

Since the degree of warming calculated as described above is displayed as a percentage on the degree of warming display section 43, the above determination is made easily and reliably. Note that the display is not used to force the bathing method, but is used as an index for teaching the timing of stopping the bathing,
Bathing can be stopped at a desired degree of warming by individual judgment.

Further, by the operations of the steps 7 and 8, an alarm is displayed when the degree of warming becomes excessive, so that a bathing accident which is particularly likely to occur when the elderly or sensory impaired take a bath is prevented. can do. The alarm display may be performed regardless of inside or outside the bathroom 1 by sounding an alarm buzzer, lighting an alarm lamp, or the like.

It should be noted that correction other than the above-mentioned room temperature,
The correction of the degree of warming based on the bathing state, the initial state of the bather, and the physique of the bather is performed to calculate the degree of warming more accurately, and it is not necessary to perform all of these. Only some parts may be implemented or not all. Alternatively, another bathing state that affects the degree of warming may be detected, and the result may be used for correcting the degree of warming.

In the above embodiment, the calculation and display of the degree of warming are performed using the control panel 4 for operation control. However, the degree of warming calculation unit 5 and the input operation unit 42 are used. May be formed separately from the control panel 4.

FIG. 6 is a perspective view of the interior of a bathroom showing another embodiment of the bathroom equipment according to the present invention. In the bathroom 1 shown in the figure, a heart rate sensor 10 provided inside the bathtub 2 is provided as a detecting means for detecting a bathing state of a bather, and only the detection result of the heart rate sensor 10 is controlled. It is given to a warming degree calculating unit 5 inside the plate 4. Other configurations inside the bathroom 1 are the same as those in FIG. 1, and corresponding portions are denoted by the same reference numerals and detailed description thereof will be omitted.

In this embodiment, the warming degree calculating section 5
Calculates the degree of warming using the actual heart rate of the bather detected by the heart rate sensor 10. As shown in FIG. 3, the degree of warming of the bather is 100 points when the blood pressure after bathing decreases by 10%.
On the other hand, since the decrease in the blood pressure of the bather is accompanied by an increase in the heart rate, if the degree of increase α (%) of the heart rate corresponding to the decrease in the blood pressure of 10% is determined in advance, The warming degree W (%) can be calculated by the following equation using the heartbeat detected by the heartbeat sensor 10.

W = (p−p ₀ ) / p ₀ × (100 / α) ×
100

[0058] In this formula p is, heart rate at the time of calculation of warm degree, p ₀ is the heartbeat of bathing at the start. In this embodiment, the degree of warming can be calculated using only the heart rate sensor 10, and there is an advantage that correction according to the bathing condition and the body condition is not required. The heart rate sensor 10 capable of accurately detecting the heart rate is higher than the sensors used in the embodiment shown in FIG. 1, that is, the hot water temperature sensor 6, the bath sensor 7, the room temperature sensor 8, and the hot water level sensor 9. In addition, since the fluctuation of the actual heart rate of the bather is large, in calculating the warming degree W, it is necessary to take into consideration the elimination of the influence of the fluctuation, such as using an average of the detected heart rate for a predetermined time. .

[0059]

As described in detail above, in the bathroom equipment according to the first aspect of the present invention, the degree of warming of the bather is calculated based on the detection result of the bathing state, and the calculation result is displayed.
