Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention monitors the concentration of carbon dioxide in bath water and the presence or absence of a bather, and adjusts the supply amounts of carbon dioxide and air to provide a higher bathing effect. The present invention relates to a bubble generation bathtub capable of obtaining a (blood circulation promoting effect).

[Prior Art] Conventionally, there are a bathtub in which carbon dioxide, which is the combustion exhaust gas of a boiler, is drawn into a bathtub, and a bath agent that generates carbon dioxide gas by dissolving in a bath. These are aimed at enhancing the effect of bathing by promoting the blood circulation effect of carbon dioxide gas. However, since the concentration of carbon dioxide gas is low (60 to 150 PPM), as shown in FIG. Only a bathing effect equivalent to that of a normal bath in which carbon dioxide is hardly dissolved can be obtained. FIG. 2 shows the change (ml / 100 cc) in the blood flow volume of the right forearm skin from the rest time by the carbonated spring.
Is during bathing, after bathing, and when moving. Normal bath with commercially available bath additives ( "Bab" CO ₂ concentration = 60PPM) and in does not change most promoting blood circulation effect. On the other hand, it can be seen that at a carbon dioxide gas concentration of 250 PPM, which is regarded as a hot spring in the hot spring method, and at a concentration of 600 PPM, a higher blood circulation promoting effect can be obtained than in a normal bath.

[Problems to be Solved by the Invention] As described above, conventional commercially available bath agents have a problem that the effect of promoting blood circulation by carbon dioxide gas cannot be sufficiently obtained.

The present invention has been made in view of such a point,
The purpose of this device is to monitor the concentration of carbon dioxide in the bath water so that the patient can take a bath after reaching a concentration of carbon dioxide that provides a higher blood circulation-promoting effect than in a normal bath. An object of the present invention is to provide a bubble generating bath in which a higher bathing effect can be obtained by synergistic effects of the carbon dioxide gas and the fine bubbles by generating the generated fine bubbles simultaneously with the carbon dioxide gas.

[Means for Solving the Problems] In the present invention, in order to solve the above-mentioned problems, as shown in FIG. 1, a fine bubble generating device 8 for generating fine bubbles in a bathtub 9 and a bathtub A carbon dioxide gas supply unit 6 and an air supply unit 7 are connected to a pipe 10 connecting the fine bubble generator 9 and the fine bubble generator 8.
A human body detector 3 for detecting the presence or absence of a bather and a carbon dioxide concentration detector 1 for detecting the concentration of carbon dioxide in bath water in a bubble generating bath connected via a gas supply amount adjusting device 5.
When the detected carbon dioxide concentration reaches a preset reference value, a signal is sent to the alarm 2 for urging bathing,
Gas supply amount adjusting device 5 according to the detection results of both detectors 3 and 1
And a control device 4 for controlling the supply amounts of carbon dioxide gas and air by controlling

The specific configuration of the microbubble generator 8 is disclosed in Japanese Patent Application No. 63-32271 (Japanese Patent Application Laid-Open No. 1-280459).

[Operation] According to the above configuration, it is possible to bathe in the microbubbles in a state where the blood circulation promoting effect of the carbon dioxide gas is higher than that of a normal bath, so that the physiological effect of bathing can be sufficiently brought out.

Embodiment FIG. 1 shows a schematic configuration of an embodiment of the present invention.
A micro-bubble generator 8 for generating micro-bubbles having a diameter of 5 to 10 μm is connected to the bath 9, and a carbon dioxide gas supply unit 6 and an air supply unit 7 are connected to a pipe 10 connecting the two. It is connected via a supply adjusting device 5. The gas supply adjusting device 5 adjusts the supply amounts of carbon dioxide and air under the control of the control device 4. The carbon dioxide concentration in the bath water is detected by the carbon dioxide concentration detector 1. The carbon dioxide concentration in the bath water measured by the detector 1 is:
When the concentration reaches the predetermined concentration of 250 PPM, the bather is prompted by the alarm 2 under the control of the controller 4. And
If bathing is confirmed by the bath detector 3, the control device 4
Is controlled by the gas supply amount adjusting device 5 to increase the supply amount of carbon dioxide gas. The annunciator 2 may notify by notifying by light or by sound, or by changing the state of bubble generation. The human body detector 3 may incorporate a method of detecting a change in the level of bath water or a change in water pressure in the bathtub, or may incorporate an optical / ultrasonic sensor.

FIG. 3 shows experimental results based on the examples, and shows changes in blood flow rate when a mixed gas of carbon dioxide and air is incorporated in microbubbles for bathing, for each carbon dioxide gas concentration. From this result, the largest increase in blood flow is due to the carbon dioxide concentration.
If rising from 250PPM, higher than 600PPM
When taking a bath as described above, the blood flow tends to decrease.
When bathing is started with the carbon dioxide gas concentration exceeding 600 ppm, the number of microbubbles is reduced by dissolving a large amount of carbon dioxide in the bath water, and a water flow is generated. It is thought that the heat insulation effect of the bath is weakened and the bather feels hot and the promotion of blood circulation is suppressed.

Therefore, when the bather is not confirmed by the human body detector 3, the predetermined carbon dioxide gas concentration should not exceed 250PPM.
The controller 4 controls the gas supply controller 5 so that the supply of carbon dioxide is reduced and the supply of air is increased. The configuration of each device is not limited to the embodiment.

[Effects of the Invention] As described above, the present invention notifies a bather that the carbon dioxide gas concentration has reached a bathing effect higher than that of a normal bath, and determines whether or not there is a bather using a human body detector. In addition, since the supply amounts of carbon dioxide and air are adjusted, the bather can take a bath with an appropriate carbon dioxide concentration, and the synergistic effect of carbon dioxide and fine bubbles provides a higher bathing effect than the ordinary bath. There is an advantage that it can be obtained.
