Carbon dioxide bubble generator for bath

The present invention is placed in a bath, such as household bathroom or public baths, bath carbon dioxide for returning the hot water in a bath microbubble carbon dioxide is mixed by mixing carbon dioxide gas while circulating hot water in the bathtub The present invention relates to a bubble generator.

  Recently, there are many cases where a bath tub is put in a bath tub and bathed in a hot spring mood, and a wide variety of bath tubs are commercially available. There are various types of bath preparations such as powders, granules, tablets, and liquids. Depending on the ingredients contained in hot water, the scent of rose, lavender, cherry scent, maple scent, There is a fragrance of red plum and a cypress. In addition, like inorganic salt baths, salts bind to proteins on the surface of the skin to form a film that forms a film. This film prevents the body from radiating heat. Those that have the effect of being difficult, such as medicinal plant baths, those that have the action of chemical components and unique fragrances contained in herbal medicines, and carbon dioxide baths that generate and generate carbon dioxide Various types have been developed.

  Of these, carbon dioxide baths, in particular, make effective use of the vasodilatory action of carbon dioxide. Carbon dioxide dissolved in hot water easily enters the skin through skin absorption and directly acts on peripheral blood vessels to widen the blood vessels. There is an effect. When blood vessels spread, the resistance of peripheral blood vessels weakens, lowering blood pressure and increasing blood flow.As a result, metabolism is promoted, and fatigue and pain are recovered. It is said to have the effect of transporting to the whole body and warming up to the core of the body.

  Focusing on the effect of the above-mentioned carbon dioxide gas, a household high-concentration carbonated hot water producing device in which carbon dioxide gas is dissolved in hot water without using a carbon dioxide bath agent has been developed and marketed. This production device uses a special hollow fiber membrane that allows carbon dioxide to pass through and does not allow water to pass through, so that high-saturation carbon dioxide (1000 ppm; 40 ° C) level is dissolved in warm water. Installation work with a built-in cartridge is unnecessary. This household high-concentration carbonated hot water maker can produce hot carbonated water with a concentration 20 times higher than when using a commercially available carbon dioxide bath, but it is expensive and has become sufficiently popular. Not in.

  More recently, as described in Patent Document 1, focusing on the effect of bubbles, a bubble bath apparatus provided with a microbubble generating nozzle that mixes air in the atmosphere to discharge microbubbles into a bathtub is disclosed. Proposed. A microbubble is an ultrafine bubble having a diameter of 10 to several tens of μm, which is smaller than a normal bubble (about 2 mm), and a product that generates this bubble in a bathtub is also commercially available. This microbubble bubble removes dirt behind the pores, scrapes waste matter accumulated in the pores, activates skin respiration, makes the skin smooth, and at the same time adjusts the autonomic nerves by the negative ion effect of the microbubbles It is said to have effects such as mental stability and blood normalization.

  In addition, a mat that is not a bathing agent but has a function of jetting warm air bubbles is laid on the bottom of the bathtub, and air is sent from the main body to the mat with an air hose so that the jet bubbles are jetted from the mat, and the bath at home is taken. A product that turns into a jacuzzi bath is on the market.

However, the above-described bubble bath apparatus and its products only have the effect of carbon dioxide gas as described above because air is bubbled and mixed into hot water.
International Publication Number WO01 / 036105

The present invention is provided with vasodilatory effects of carbon dioxide, focusing on efficacy due to the air bubbles of the microbubbles, a new bath carbon dioxide bubble generator capable of generating microbubbles carbon dioxide having these effects and efficacy Doing that is the task.

  The configuration of the present invention made for the purpose of solving the above problems is a carbon dioxide generator, a gas mixer for mixing carbon dioxide generated in the generator with hot water in the bathtub, and the bathtub. The pump is equipped with a pump for introducing hot water in the bathtub from the inlet and discharging the hot water mixed with carbon dioxide gas from the outlet through the mixer into the bathtub, and the generator is connected to the mixer at high speed. By flowing carbon dioxide into the flowing hot water, hot water mixed with carbon dioxide microbubbles is discharged into the bathtub.

  In the above-described configuration, the present invention can be configured to generate carbon dioxide in the carbon dioxide generator by putting a carbon dioxide bathing agent in a water tank of the carbon dioxide generator. Further, the carbon dioxide bathing agent can contain scent components such as rose and lavender.

  The apparatus of the present invention uses a commercially available carbon dioxide bathing agent, and the generated carbon dioxide gas is microbubbled and mixed in the circulating hot water, so that the capillaries can be expanded by the carbon dioxide gas and the bubbles of the microbubbles are obtained. The effect that the dirt behind the pores due to can be removed can be obtained. In particular, the same effect as aerobic exercise can be obtained by the capillary vasodilator action by carbon dioxide gas, and since hot water becomes acidic, the blood glucose level can be lowered, and a special effect of being effective for diabetes can be obtained. In addition, when the carbon dioxide bathing agent used contains a scent component such as rose or lavender, the generated scent is mixed in the hot water circulating together, so that you can further feel the hot spring feeling.

Next, an embodiment of the present invention will be described with reference to the drawings. Figure 1 is a partial cross-sectional front view showing the internal structure of an example of the present invention bath carbon dioxide bubble generator, FIG 2 is X-X arrow line cross-sectional plan view of the apparatus shown in FIG. 1, tub 3 is the device of the present invention FIG. 4 is a side sectional view showing another example of a state in which the device of the present invention is installed in a bathtub.

In the figure, 1 is an outer container an example of bath carbon dioxide bubble generator A of the present invention, the container 1 is inside is divided by a partition wall 2. 3 is a carbon dioxide generating chamber divided by the partition wall 2 and 4 is a gas mixing chamber. In addition, the upper end of the partition wall 2 is located below the upper wall inner surface of the outer container 1, and a gap S is formed between the upper wall inner surface and the upper end inner surface. Due to the gap S, the carbon dioxide generating chamber 3 and the gas mixing chamber 4 are connected so as to allow ventilation.

  The carbon dioxide generation chamber 3 side is further divided into upper and lower portions by a partition wall 5, and the pump P is accommodated in a space formed on the lower side. As will be described later in detail, the pump P is for introducing hot water from the bathtub B and discharging hot water mixed with carbon dioxide into the bathtub B.

The carbon dioxide generating chamber 3 is a water tank for containing water w. When the carbon dioxide bath 6 is added, the carbon dioxide generating chamber 3 reacts with the water w to generate carbon dioxide as bubbles 7. 1a is an openable / closable lid provided on the upper wall of the outer container 1. Usually, before the bathing, the lid 1a is opened and a predetermined amount of the carbon dioxide bath 6 is poured into the water w. As the carbon dioxide bath agent 6, a solid one is used, but a powdery or granular one may be used. Here, carbon dioxide is generated by a combination of water and a carbon dioxide bathing agent, but other combinations may be used as long as carbon dioxide can be generated. For example, the carbon dioxide gas may be supplied from a conventionally known carbon dioxide gas cylinder, or the carbon dioxide gas cylinder and the carbon dioxide-based bath agent may be used simultaneously or by switching.

  The carbon dioxide gas generated in the carbon dioxide generation chamber 3 accumulates in the upper portion of the chamber 3 and moves to the gas mixing chamber 4 side through the gap s. However, in the apparatus of the present invention, the generated carbon dioxide is used for the operation of the pump P. Accordingly, the gas is mixed into the gas mixing chamber 4 side.

In the present invention the bath carbon dioxide bubble generator introduces the hot water in the bathtub B by the pump P as described above, and discharges the bath B by mixing carbon dioxide gas. Reference numeral 8 denotes an introduction pipe connected to a pump P for introducing hot water in the bathtub B into the apparatus. The inlet 8a of the introduction pipe 8 has a hot water suction pipe 9 whose tip side is placed in the bathtub B. The rear end is attached.

  Reference numeral 10 denotes a discharge pipe connected to the pump P, and reference numeral 11 denotes a gas mixer attached in the middle of the discharge pipe 10. This gas mixer is in the gas mixing chamber 4 for sucking the carbon dioxide gas generated in the carbon dioxide generating chamber 3 and mixing it with hot water flowing through the mixer 4 at high speed. 11 a is a suction pipe provided on the side of the gas mixer 4, and 11 b is a stirring blade attached to the inner wall surface of the gas mixer 4. The hot water flowing by the stirring blade 11b is stirred in the gas mixer 4 and mixed with the carbon dioxide gas sucked by the suction pipe 11a, and microbubbles are generated in the process. Although not shown, the suction pipe 11a is provided with a check valve for preventing the backflow of the sucked carbon dioxide gas and preventing the hot water from flowing into the gas mixing chamber 4. By the suction of the carbon dioxide gas by the suction pipe 11a, the carbon dioxide gas generated in the carbon dioxide gas generation chamber 3 is sucked to the gas mixing chamber 4 side through the gap s.

  Microbubbles are generated in the gas mixer 4 as described above, but this is an example, and a commercially available microbubble generator can be used to generate microbubbles.

  Next, the hot water mixed with the microbubbles of carbon dioxide gas flowing out from the gas mixer 4 reaches the discharge port 10a through the discharge pipe 10, and enters the bathtub B by the hot water discharge pipe 12 attached to the discharge port 10a. By discharging, carbon dioxide gas made into a bubble is mixed into the hot water in the bathtub B. Reference numeral 13 denotes a switch provided on the front surface of the outer container 1.

Next, FIG. 3, with reference to FIG. 4, how to install the bath carbon dioxide bubble generator A of the present invention. FIG. 3 shows that the device A of the present invention is mounted on the wall surface of the bathroom in a wall-mounted manner, the hot water suction pipe 9 and the hot water discharge pipe 12 are connected to the suction port 8a and the discharge port 10a of this device A, respectively, The state put in is shown. Although not shown, the apparatus A of the present invention may be attached outside the bathroom, and the hot water suction pipe 9 and the hot water discharge pipe 12 may be drawn into the bathroom from there.

  FIG. 4 shows that the apparatus A of the present invention is installed on the side of the tub B at substantially the same height, and hot water mixed with carbon dioxide microbubbles is put into the tub B by the short hot water intake pipe 9 and the hot water discharge pipe 12. It shows the state that can be.

  The present invention apparatus A is installed as shown in FIG. 3 and FIG. 4, and a microbubble generation state when a commercially available carbon dioxide bath bab (registered trademark) is placed in the carbon dioxide generation chamber 3 When the pH of the hot water in the bathtub B was measured by changing the number of bathing agents used and the temperature of the circulating hot water, a large amount of carbon dioxide microbubbles was generated in each case. The pH of the hot water was as shown in Table 1. It was found that the hot water becomes more acidic as the temperature of the hot water increases and the number of bathing agents increases.

  The present invention does not use a commercially available carbon dioxide bathing agent directly in the bathtub, but mixes the bubbles of carbon dioxide generated by the bathing agent with microbubbles and circulating hot water, and discharges it into the bathtub. As a result, both the effects of carbon dioxide and microbubbles can be obtained, and the hot spring feeling can be enjoyed, and at the same time, the effects similar to aerobic exercise can be obtained by capillary vasodilation. The effect of being able to remove the dirt behind is obtained. Although it is a subject for future research to determine what kind of disease these effects actually work, it is very likely to be effective for diabetes, gout, heart disease, kidney disease, hypertension, atopic dermatitis and the like.
