Further, the bathing apparatus of the present invention is configured such that the nozzle is sprayed with hot and cold water.

Since the bather is wrapped in the mist of hot water, the hot water supplied with the substance can be evenly bathed in the whole body, and the effect of the supplied substance on the body can be promoted.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. (Embodiment 1) FIG. 1 is a configuration diagram of a bathtub apparatus according to Embodiment 1 of the present invention.

In FIG. 1, reference numeral 12 denotes a bathtub,
Numeral 2 is connected to supply means 13 (for example, a hollow fiber membrane or the like) for dissolving carbon dioxide gas through circulation paths 14 and 15. Reference numeral 16 denotes a pump for circulating hot water in the bathtub 12 between the hot water supply means 13 and the supply means 13, and is controlled by the control means 17.

Carbon dioxide supplied from the supply means 13 to the hot and cold water for the purpose of promoting blood circulation is supplied from the cylinder 18 to the electromagnetic valve 1.
9, is supplied via supply amount adjusting means 20. The electromagnetic valve 19 is controlled by the control means 17 so as to be opened when the carbon dioxide gas is supplied from the cylinder 18 filled with the carbon dioxide gas, and to be closed when the carbon dioxide gas is not supplied. The supply amount adjusting means 20 adjusts the amount of carbon dioxide gas supplied from the supply means 13 to the hot water by adjusting the pressure of the carbon dioxide gas in the supply means 13.

Reference numeral 21 denotes a blood flow detecting means which is a human body information detecting means for detecting a blood flow of a bather in the bathtub, and is provided at a position where the bather's body in the bathtub comes into contact with the bather's blood flow data. Is output to the control unit 17. The blood flow detecting means 21 detects the flow of red blood cells in the blood vessel by using the laser Doppler effect.

The control means 17 detects the bathing and measures the blood flow by the blood flow detecting means 21, and sets a blood flow setting range set so that the bather can take a comfortable bath with a small physical burden. Measure the deviation of Thereafter, when carbon dioxide gas supply is necessary, the pump 16 is driven to drive the circulation path 14,
The hot and cold water is circulated in the chamber 15 and the electromagnetic valve 19 is opened.

In the above configuration, the operation and operation of this embodiment will be described with reference to the operation explanatory diagram of FIG.

When the bather selects the operation of the bathtub apparatus by operating means (not shown), or when hot water is poured into the bathtub 12, the bathtub apparatus is activated, and the control means 17 controls the blood flow of the blood flow detecting means 21. Start flow detection. When the bather enters the bathtub 12, the data from the blood flow detecting unit 21 fluctuates, and the control unit 17 starts measuring the initial bathing value. The blood flow detected at this time is a value detected because the bather has entered the bathtub, and is not an original blood flow value but a time when this initial fluctuation occurs is set as a bathing start time. When the measurement of the blood flow value is started and the bather has a small physical burden and is out of the blood flow setting range set so that a comfortable bath can be performed, the detected blood flow value and the setting range are compared. The supply amount of carbon dioxide is changed according to the deviation.

Here, carbon dioxide is a component that is absorbed from the skin surface, expands blood vessels, and promotes blood flow. As the concentration of carbon dioxide increases, blood flow is further promoted. In this embodiment, since the amount of hot water applied to the bathtub 12 is known, the concentration of carbon dioxide in the bathtub can be calculated from the supply amount of carbon dioxide gas, and the blood flow is controlled by the supply amount of carbon dioxide gas.

When dissolving the carbon dioxide gas, the control means 17 first opens the solenoid valve 19 and introduces the carbon dioxide gas from the cylinder 18 into the supply amount adjusting means 20. The supply amount adjusting means 20 adjusts the carbon dioxide gas pressure in accordance with the deviation between the blood flow from the blood flow detecting means 21 and the set range, that is, adjusts the carbon dioxide gas pressure in the supply means 13, and sets the circulation paths 14 and 15. Supply carbon dioxide to hot and cold water.

In FIG. 2A, the detected blood flow is low in the early stage of bathing, and the deviation from the set range is large. Therefore, a large amount of carbon dioxide gas is supplied to promote the blood flow more quickly. When the blood flow value rises (the deviation decreases), the bathtub 12
The amount of carbon dioxide in the inside is increasing, and the supply of carbon dioxide is reduced to smoothly increase blood flow. This also suppresses an increase in blood flow beyond a set range by supplying a large amount of carbon dioxide gas, and conversely, an increase in the burden on the body, even though the deviation is small. Until the blood flow falls within the predetermined range, the supply amount of carbon dioxide is reduced stepwise according to the decrease in the deviation. When the blood flow enters a predetermined range, the supply amount of carbon dioxide is gradually reduced to a minimum necessary amount to maintain the blood flow within the predetermined range. In this figure, the blood flow is not reduced, but if the blood flow decreases with a decrease in the gas supply amount and the deviation tends to occur again, the carbon dioxide gas supply amount is increased.

When the bather gets out of the bathtub 12, the data from the blood flow detecting means 21 is greatly reduced, so that the end of bathing can be determined. If the carbon dioxide gas is supplied, the solenoid valve 1 is immediately turned off.
9 is closed.

In this embodiment, as shown in FIG. 2 (b), it is conceivable that the blood flow becomes constant without entering the set range. The unnecessary supply of carbon dioxide gas is prevented by not supplying the carbon dioxide gas but supplying the minimum necessary amount of carbon dioxide gas to maintain a constant blood flow outside the set range.

As described above, in this embodiment, the blood flow detecting means 2
Since the supply amount of carbon dioxide is adjusted according to the blood flow of the bather from the beginning, maintenance is not required for a long time without using unnecessary carbon dioxide.

Further, since the supply amount of carbon dioxide is adjusted stepwise according to the deviation between the detected blood flow and the blood flow within a predetermined range, the carbon dioxide can be used more effectively.

Further, when the bather has a small physical burden and falls within a blood flow setting range which is set so that a comfortable bath can be performed, a minimum carbon dioxide gas supply for maintaining the blood flow is performed, so that blood circulation is promoted. It is moderately planned and you can enjoy safe and suitable bathing.

Since carbon dioxide is dissolved in hot and cold water to promote blood circulation, it is possible to experience a carbonated spring bathing at home as if it were a hot spring.

The bather enters the bathtub 12 or
Since the detection value from the blood flow detection means 21 greatly fluctuates when leaving, and the presence or absence of bathing is determined based on the fluctuation of the detection value, it is necessary to provide a means for detecting that a new bather has entered the bathtub 12. Absent.

Although the blood flow detecting means 21 is configured to be fixed to the bathtub 12, a similar effect can be obtained as long as the configuration is such that the bather can wear the blood bath and detect the blood flow.

Although the carbon dioxide gas is supplied from the cylinder 18, the same effect can be obtained by collecting the carbon dioxide gas in the atmosphere or using a solid or liquid bath agent that generates carbon dioxide gas. can get.

The same effect can be obtained even if the temperature detecting means is set as a blood pressure detecting means for detecting the blood pressure of the bather so that the bather can set a blood pressure setting range so that the bather can perform a comfortable bath with less physical burden. Is obtained.

(Embodiment 2) FIG. 3 is a block diagram of a bathtub apparatus according to Embodiment 2 of the present invention. Only the differences from Embodiment 1 will be described, and the other parts will be assigned the same reference numerals and omitted.

In FIG. 3, reference numeral 22 denotes a supply means for supplying a bath agent, which is a substance, to the hot water flowing through the circulation paths 14, 15.

The bath agent supplied to the hot water for the purpose of relaxing the bather and lowering the heart rate is stored in a tank 23 and is pressurized by a pump 24 which is a concentration adjusting means. Supplied. The pump 24 is driven by the control means 17 when supplying the bath agent, and the supply amount of the bath agent is controlled by pressurizing the pump 24.

Reference numeral 25 denotes a separating means which is a concentration adjusting means for separating the bathing agent supplied to the hot and cold water, which is controlled by the control means 17 so that the bathing agent is separated from the hot and cold water in the circulation paths 14 and 15 and returned to the tank 23. Communicating.

The density detecting means 26 is provided in the circulation paths 14 and 15
That is, the concentration of the bath agent in the bathtub 12 is detected, and a signal is output to the control means 17.

Reference numeral 27 denotes a heart rate detecting means which is a human body information detecting means for detecting a heart rate of a bather in the bathtub, and is provided in the bathtub and outputs the bather's heart rate data to the control means 17.

The control means 17 detects the bathing and measures the blood flow by means of the heartbeat detecting means 27, and is set so that the bather can perform a comfortable bathing with less physical burden and recovering from fatigue. Measure the deviation from the heart rate setting range.
When there is a deviation and it is necessary to supply the bath agent to suppress the heart rate, the pump 16 is driven to circulate hot and cold water in the circulation paths 14 and 15, and a bath agent set in advance according to the deviation is set. The pump 24 is operated so as to obtain the concentration.

In the above configuration, the operation and operation of this embodiment will be described with reference to the operation explanatory diagram shown in FIG.

When the bather selects the operation of the bathtub apparatus by operating means (not shown), or when hot water is poured into the bathtub 12, the bathtub apparatus is started, and the heart rate detection means 27 detects the heart rate by the control means 17. To start. When the bather enters the bathtub 12, the data from the heartbeat detecting unit 21 fluctuates, so that the control unit 17 starts measuring the initial bathing value. When the heart rate measurement is started and the bather has a small physical burden and is outside the heart rate setting range set for comfortable bathing, the difference between the detected heart rate and the set range is determined according to the deviation. To change the concentration of bath salt.

Here, the bathing agent contains a carbonated component or an aromatic component, and relaxes the bather and reduces the heart rate. In the present embodiment, the heart rate setting range is set so as to suppress an increase in heart rate that occurs at the time of bathing and to reduce a burden on the body due to an excessive decrease in heart rate.

When dissolving the bath agent, the control means 17 controls the pump 24 to adjust the supply pressure according to the deviation between the heart rate from the heart rate detection means 27 and the set range, that is, the supply means 22.
To adjust the pressure of the carbon dioxide gas at, and supply the bathing agent to the hot and cold water passing through the circulation paths 14 and 15 until the bathing agent concentration reaches the concentration corresponding to the deviation. Further, as the deviation of the heart rate becomes smaller, the bathing agent is separated by the separating means 25 in order to suppress the bathing agent concentration, and the separated bathing agent is returned to the tank 23. When the heart rate falls below the set range and a deviation occurs, the concentration of the bath salt is further reduced to promote an increase in the heart rate.

FIG. 4 shows an example when taking a bath. The heart rate rises sharply when taking a bath, and the deviation from the set range is large.
To reduce the heart rate more quickly, supply a bath agent to maintain a high concentration. When the heart rate decreases (the deviation decreases), the concentration of the bath salt in the bathtub 12 is gradually reduced to prevent a rapid change in the heart rate. This means that, even though the deviation is small, if the concentration of the bath agent is increased, the heart rate is reduced below the set range, and conversely, the burden on the body is suppressed from increasing. When the heart rate falls within a predetermined range, the concentration of the bath additive is gradually reduced to a minimum necessary amount to maintain the heart rate within the predetermined range.

When the bather gets out of the bathtub 12, the data from the heart rate detecting means 21 is greatly reduced, so that the end of bathing can be determined.
To stop. After completion of bathing, the bathing agent is separated from the separating means 25.
Can be collected and reused.

As described above, in this embodiment, the heartbeat detecting means 2
Since the concentration of the bath salt is adjusted and separated and collected according to the heart rate of the bather detected from step 7, maintenance is not required for a long period of time without using waste bath salt.

Further, since the concentration of the bath agent is adjusted according to the deviation between the detected heart rate and the heart rate set range, the bath agent can be used more effectively.

Further, when the bather's physical load falls within the heartbeat setting range set so as to allow comfortable bathing, the minimum concentration of the bathing agent is maintained so that the bather can relax moderately. This makes it possible to reduce the burden on the heart.

A bather enters the bathtub 12 or
Since the detection value from the heart rate detection means 27 greatly fluctuates when leaving, and the presence or absence of bathing is determined based on the fluctuation of the detection value, it is not necessary to provide a means for detecting that a new bather has entered the bathtub 12. .

Although the heart rate detecting means 27 is fixed to the bathtub 12 and provided at a position in contact with the human body, the same effect can be obtained as long as the heart rate can be detected by, for example, wearing a bather by himself. Can be Also, the concentration of the bath salt may be determined from various data such as the interval between heartbeats as well as the heartbeat rate, and may be used as an index of relaxation or burden on the body. In this embodiment, the bath agent is described as a reusable bath agent. However, when the bath agent cannot be reused, the bath agent separated by the separation means 25 is stored in the tank 23.
It is good also as composition which does not return to. Furthermore, even if it does not provide the separation means 25, there is an effect that the bath agent to be used can be suppressed to the minimum.

The concentration detecting means 26 may be provided at any position as long as the concentration of the bathing agent in hot and cold water can be measured, such as in the bathtub 12.

In this embodiment, the bather is relaxed by the bathing agent. However, the bathing agent may be relaxed by the supply substance fragrance.

Similar effects can be obtained by using the separation means 25 as a concentration diluting means for filtering and decomposing substances such as bathing agents and deaeration to reduce the substance concentration. In addition, the diluting means is not limited to this, as long as the concentration is reduced by increasing the amount of hot water or the like.

(Embodiment 3) FIG. 5 is a perspective view of a shower apparatus according to Embodiment 3 of the present invention, and FIG. 6 is a view of the same flow path configuration. Attached and omitted.

In the shower device 28, a chair 29 is a rotatably provided seating means so that a user can sit down and take a bath with hot water. It is possible. Also, 30
Is a rotatably provided arm, which is set as shown in FIG. 5 when the user sits down and takes a bath,
When the shower device 28 is not used, it can be stored in the direction of the wall 31 when not in use.
The washing area 33 can be used widely, and a sense of visual oppression can be prevented.

The arms 30 are provided with nozzles 34 symmetrically to the left and right, and are arranged so that hot water can be jetted from the ends to the legs, abdomen, and chest. Also, the cover 35 of the shower device 28 is provided with nozzles 34 as hot water jetting means symmetrically on the left and right sides.
It is arranged so that hot water can be spouted around the waist. The nozzle 34 is configured to spray hot water in the form of a mist and wrap the whole body, so that the amount of hot water used is smaller than that of a normal hand shower.

Reference numeral 36 denotes a hand shower, and the nozzle 34
When the whole body shower 37 is not used, it can be used as a normal shower.

The flow path of the shower device 28 is as shown in FIG. The hot water supply pipe 38 and the water supply pipe 39 communicate with a mixing valve 40 for adjusting the mixing ratio of hot water and adjusting the hot water temperature.
By rotating the hot water temperature adjusting knob 41 of the mixing valve 40, the valve opening of hot water is adjusted and the hot water temperature is adjusted.

Downstream of the mixing valve 40, a supply means 42 for dissolving carbon dioxide in hot and cold water is provided. Carbon dioxide is supplied to the supply means from the cylinder 18 via the electromagnetic valve 19 and the concentration adjusting means 43. The concentration adjusting means 43 adjusts the amount of carbon dioxide dissolved in the hot water by adjusting the supply pressure of the carbon dioxide, and adjusts the carbon dioxide concentration in the hot water. The carbon dioxide gas concentration at this time is adjusted by the control means 17 determining the valve opening of the concentration adjusting means 43 from the flow rate of hot and cold water detected by the flow rate sensor 44 which is a concentration detecting means provided downstream of the supply means 42. ing.

The switching valve 45 switches between the hand shower 36 and the whole body shower 37 constituted by the nozzle 34, and the switching knob 46 can be used to stop water and adjust the flow rate.

Reference numeral 47 denotes a temperature detecting means which is a human body information detecting means for measuring a bather's body temperature.
7 is output. The temperature detecting means 47 is provided on the surface of the chair 29 in contact with the body, and can detect blood pressure and body temperature when sitting. In particular, if it is provided on the seating surface of the chair 29, there is not much individual difference in the seating position of the bather, so that it is possible to reliably contact the bather.

The control means 17 measures the blood pressure and the body temperature by means of the temperature detecting means 47, and sets the body temperature so that the bather can perform a comfortable bath without a physical burden and feel the burning after bathing. Compare with the setting range. Control means 1
7, when there is a deviation between the detected body temperature and the body temperature setting range,
When the body temperature is high, the carbon dioxide gas concentration is reduced by the concentration adjusting means 43 according to the deviation, thereby suppressing blood circulation and lowering the body temperature. If the body temperature is low, increase the carbon dioxide concentration according to the deviation,
Promote blood circulation and increase body temperature.

The operation and operation of the present embodiment in the above configuration will be described. When the hand shower 36 or the whole body shower 37 is opened by the switching knob 46, hot water is supplied to the mixing valve 40, and the hot water is mixed with the hot water set by the hot water temperature adjusting knob 41 at the mixing valve 40. When the switching knob 46 is opened to the whole body shower side 37, the control means 17 is simultaneously activated. At this time, even if the hand shower 36 side is opened, the control means 17 does not operate, and in the case of the hand shower 36, the carbon dioxide gas is not supplied unless the operation unit (not shown) selects the carbon dioxide gas supply. ing.

When the whole body shower 37 is opened and the seating of the bather is confirmed by the temperature detecting means 47, the control means 17 starts detecting the body temperature by the temperature detecting means 47 and also obtains a flow signal from the flow sensor 44. . At this time, the detected body temperature is compared with a body temperature setting range that is set so that the bather can perform a comfortable bath with less physical burden and not feel hot after bathing. There is a deviation between the measured body temperature and the body temperature setting range. If the body temperature is high, the carbon dioxide gas concentration is reduced by the concentration adjusting means 43 according to the deviation, thereby suppressing blood circulation and lowering the body temperature. When the body temperature is low, the concentration of carbon dioxide is increased in accordance with the deviation to promote blood circulation and increase the body temperature.

FIG. 7 shows an example when taking a bath. The body temperature gradually rises when taking a bath, but since the deviation from the set range is large, the concentration of carbon dioxide is maintained at a high level in order to increase the body temperature more quickly. When the body temperature approaches the set range (the deviation decreases), the carbon dioxide concentration in the hot water is gradually reduced,
The body temperature is prevented from rising too much and the amount of carbon dioxide used is suppressed. This is because even if the deviation is small, if the concentration of carbon dioxide is high, the body temperature will rise beyond the set range, and on the contrary, burden on the body, hot flashes, and burning after bathing will occur It is for suppressing. When the body temperature falls within a predetermined range, the concentration of carbon dioxide is gradually reduced to a minimum necessary amount to maintain the body temperature within the predetermined range.

The carbon dioxide gas concentration is calculated with high accuracy by calculating the required supply amount from the flow rate of hot water detected by the flow rate sensor 44 in the control means 17 and adjusting the carbon dioxide gas supply pressure of the supply means 42 by the concentration adjusting means 43. Can be controlled.
