Description

  In the present invention, a purification device, a circulation pump, a sterilization device, and a heater are arranged in a circulating water channel having a water inlet and a discharge port installed in a bathtub to purify and sterilize the bathtub water stored in the bathtub. The present invention relates to a circulating bath device for heating and maintaining a bath water at an appropriate temperature at all times, and more particularly to a circulating bath device capable of supplying carbon dioxide, characterized in that fine bubbles of carbon dioxide can be supplied to the bath water. is there.

  Conventionally, for example, as shown in FIG. 5 and FIG. 6, a circulating purification device 3 having, for example, mineral stone and microorganism filtration, A circulation pump 4, a sterilizer 5 using a hypochlorous acid generated by electrolyzing salt in a small electrolytic tank, an ozone generator, an ultraviolet generator, and a heater 6 are arranged and stored in the bathtub 1. A circulating bath device that purifies, sterilizes, and heats the bathtub water 7 to maintain the bath water at an appropriate temperature at all times is used. It is widely used as a so-called 24-hour bath, and each device is housed in a small casing 8. Small household ones are also available on the market.

  It is also known that an air pump 4 is arranged at the discharge port 2 of the circulating bath device (24-hour bath) to eject a fine bubble to obtain a massage effect and a visual effect. It is not enough as an added value because it is as large as 10 microns.

  By the way, recently, bathtub water (carbonated spring) in which fine bubbles of a predetermined amount of carbon dioxide gas dissolve has been used for bathing and showering etc. for the purpose of recovery of fatigue and beauty by improving the peripheral blood circulation of the human body, It is known that bubbles having a fine bubble diameter and called nanobubbles have a sterilizing and purifying action, and a circulating bath apparatus (24-hour bath) is also required to use carbonated springs.

  A simple means for obtaining a carbonated spring is known, for example, as disclosed in JP-A-2005-314233, in which a method using a chemical using carbonate and acid is known. However, the amount dissolved in the bath water is small (concentration of about 300 mg / L) is not enough to exert the effect as a carbonated spring. Since the generation of carbon dioxide gas ends in a short time, it is unsuitable for use in a circulating bath device (24-hour bath) where bathing is possible at any time. In addition, there is a problem that a component that affects the equipment of the circulating bath apparatus is also added.

  Therefore, a high concentration carbonated spring can be generated at the desired bathing time. In other cases, the pump speed is reduced and the bathtub water is circulated through the bypass pipe to save energy and noise, and to maintain a suitable temperature for 24 hours. A soaking bath is presented in Japanese Patent Application Laid-Open No. 2006-23954.

  The 24-hour bath that can provide carbonated springs as disclosed in Japanese Patent Application Laid-Open No. 2006-23954 is a solution that efficiently circulates bathtub water and the like by spraying water into a pressure vessel filled with carbon dioxide gas and dissolving the carbon dioxide gas efficiently. And large-sized ones using hollow fiber membranes such as those disclosed in Japanese Patent Publication No. 8-4731, Japanese Patent Laid-Open No. 2001-293342, Japanese Patent Laid-Open No. 2004-136272, etc., which are conventional means for forming carbonated springs. The device has the advantage of not generating noise and noise.

However, the 24-hour bath presented in JP-A-2006-23954 requires a carbon dioxide gas cylinder and a pressure vessel as a device for generating fine bubbles of carbon dioxide gas, and the equipment is enlarged, It is not easy to handle and cannot be used by being incorporated into a small casing 8 that can be used even in a bathtub installed in a bathroom of the home as shown in FIGS.

  The present invention has been made to solve the above-described problems. In addition to being able to supply fine carbon dioxide bubbles when desired, the present invention can be used as a carbonated spring, and has a simple structure. It is an object of the present invention to provide a circulating bath device (24-hour bath) that can be incorporated into a housing and can be easily operated.

  The present invention made in order to solve the above-mentioned problems, a purifier, a circulation pump, a sterilizer, and a heater are arranged in a circulating flow channel having a water suction port and a discharge port installed in the bathtub, and the bathtub has A carbon dioxide generating device that purifies, sterilizes, and heats the stored bathtub water to maintain the bath water at an appropriate temperature at all times, and generates carbon dioxide by electrolyzing the bathtub water added with carbonate to the circulating flow channel. It arrange | positions and enabled it to supply the fine bubble of a carbon dioxide gas to the said bath water.

  The present invention electrolyzes bath water to which carbonate has been added by a carbon dioxide generator arranged in a circulating flow channel to produce fine bubbles of carbon dioxide (having a diameter of at least 50 [μm] or less) (hereinafter “microbubbles”). ”) Is circulated to the circulating bath water to produce a carbonated spring in which a high concentration (at least 1000 [m / L] or more) of carbon dioxide gas is dissolved in a short time.

  According to the present invention, a carbon dioxide gas generator is arranged in a branch channel formed in a circulation channel, and a branch valve capable of adjusting the flow rate when the branch channel is opened and closed and opened is always installed in the branch channel. Closes the on-off valve and stops the supply of bath water to the carbon dioxide generator, and when necessary, that is, when bathing, opens the on-off valve to supply the bathtub water to the carbon dioxide generator to perform electrolysis. By generating carbon dioxide by supplying carbon dioxide to the circulating flow channel, the carbon dioxide can be generated very efficiently, and by making the on-off valve adjustable in flow rate, a desired amount of carbon dioxide can be supplied. it can.

  In addition, by connecting the branch channel before and after the sterilization device of the circulating flow channel, it can be arranged in parallel with the sterilization device, so that the inhibition of carbon dioxide generation due to electrolysis by the sterilization device can be prevented. When a carbonate addition device is disposed at the inlet of the carbon dioxide generator in the branch water channel, adding carbonate to the circulating bath water when necessary, that is, bathing Can be economical.

  In particular, when the carbonate contains at least sesquicarbonate, the dissolution rate is faster than when using carbonates such as sodium carbonate and sodium hydrogen carbonate, so that electrolysis can be performed at the same time as bathing and electrical conductivity is high. In addition to being able to quickly and efficiently generate carbon dioxide microbubbles, it is possible to obtain a pH value suitable for bathing by suppressing an extreme rise in the pH value of bath water. In addition, the carbon dioxide generator can efficiently generate carbon dioxide microbubbles by using an electrolyzer having a diaphragm, and the electrical resistance can be reduced by arranging the anode and the cathode close to each other. It is possible to achieve electric power, and the bubbles of carbon dioxide generated by making the electrolytic cell flow type do not stay in the electrolytic cell, preventing the increase in electrolytic resistance due to the bubbles of carbon dioxide. A decrease in the amount of carbon dioxide generated due to a decrease in the electrolysis current can be prevented.

  Further, when the applied electrolytic current density is equal to or higher than the limit current density, the shielding effect (the effect that the generated gas adheres to the electrode) and the dispersion effect (the effect that the bubbles generated at the electrode are dispersed in the electrolytic solution and the resistance is increased). ) And a large amount of carbon dioxide microbubbles can be generated.

  When the carbon dioxide generator has a constant current power supply, the electric conductivity of the bath water electrolyzed by the addition of carbonate is prevented from increasing and an overcurrent state is prevented, so that a constant current is always maintained. A stable electrolytic state can be obtained.

  Furthermore, the sterilizer is based on chlorinated water generated by adding saline to the bath water and electrolyzing with an electrolyzer, and when the electrolyzed carbon dioxide generator is juxtaposed with the electrolyzer. The structure of the switching process between the sterilization device and the carbon dioxide generator in the circulating flow channel is easy, and the power supply device used for the sterilizer can be easily used in the carbon dioxide generator. When the purification device, the circulation pump, the sterilization device, the heater, and the carbon dioxide generator are housed as a single unit in a housing, the conventional household bathtub is used. It can also be installed without taking up space just like a small 24-hour bath that can be used.

  According to the present invention, in a circulating bath device (24-hour bath) that maintains a bath water at a proper temperature at all times that has been conventionally used, fine bubbles (nano bubbles) of carbon dioxide gas can be easily and efficiently added to the bath water when desired. It can be supplied and can be made very compact.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  FIGS. 1 and 2 are a plan view and a front view showing the arrangement of a preferred embodiment of the present invention. Like the conventional circulating bath apparatus (24-hour bath) shown in FIGS. 5 and 6, Salt is collected in a circulating flow channel 2 having a water inlet 21 and a discharge port 2 disposed in the bathtub 1 by a circulating purification device 3 in which mineral stones such as wheatstone are accumulated, a circulation pump 4 and a small electrolytic cell. Inside the housing 8 are an electrolysis device 9 equipped with a sterilization device 5 using chlorinated water (hypochlorous acid water) generated by electrolysis, an air pump 4 for ejecting fine bubbles to the discharge port 22, and the like. Is arranged.

  In the electrolyzer 9, the sterilizer 5 is arranged between the circulation pump 4 and the heater 6, and a carbon dioxide generator 10 is arranged between the purification device 3 and the circulation pump 4. A carbonate addition tank 11 is arranged in the vicinity of the inlet of the purification device 3 in the circulation channel 2.

  FIG. 3 shows an electrolysis device of the carbon dioxide generator 10 in the present embodiment, which is a thin box-like shape in which an inlet 101 for bath water is formed at one end and an outlet 102 is formed at the other end. A plate-like anode 104 and a cathode 105 whose surfaces are covered with platinum (or platinum iridium alloy) are disposed in the inside of the electrolytic cell 103 in close proximity to each other with a non-diaphragm sandwiching the bathtub water channel 106 therebetween. Are connected to the anode 104 and the cathode 105. The connection terminals 107 and 108 supply power to the sterilizer 5 and the circulation pump 4, and control relays for various devices. And a power supply device 12 including a control circuit and the like.

  Next, the operation process of the present embodiment having the above configuration will be described with reference to the operation circuit schematic diagram shown in FIG. First, when an outlet is plugged into a household power supply (100V), Sw1 (main power switch) is turned on and an input switch (not shown) is turned on, Sw2 (pump activation) via a control relay by a start switch circuit Switch) is turned ON, the circulation pump 4 is activated, the bathtub water 7 stored in the bathtub 1 is supplied from the water inlet 21, the purification device 3, the circulation pump 4, the sterilization device 5 through the circulation flow channel 2, It circulates in order of the heater 6 and circulates from the discharge port 22 to the bathtub 1. At this time, Sw3 (heater start switch) is automatically turned ON / OFF by the thermistor and the temperature control board, and the water temperature of the bath water is maintained at a desired temperature by the heater 6, and Sw3 ( The heater start switch is automatically turned on and the sterilizer 5 is operated by supplying the DC power source transformed to a predetermined voltage by the Rf1 / DC exchange circuit to the salt water electrolyzer, so that the desired temperature is always maintained. It can be used as a circulating bath (24-hour bath) that can keep bath water purified and sterilized at any time.

  In order to make the bath water 7 into a carbonated spring, the carbonate addition tank 11 is filled with carbonate, the carbonate is dissolved in the circulation flow path 2, and a carbonated spring generation switch (not shown) is turned on to turn the bath water 7 on. A DC power source transformed to a predetermined voltage is supplied to the carbon dioxide electrolysis tank of the carbon dioxide generator 10 provided in parallel with the electrolysis apparatus 9 through the relay circuit and the Rf2 / DC exchange circuit to the salt water electrolysis tank for electrolysis. Then, bath water containing microbubbles of carbon dioxide gas is generated and sequentially discharged from the discharge port 22 of the circulation channel 2 to the bathtub 1.

In addition, as carbonate to add, common things, such as sodium carbonate and sodium hydrogencarbonate, may be used alone or in combination, but sodium sesquicarbonate (Na ₂ CO ₃ · NaHCO ₃ · 2H ₂ CNa ₂ CO ₃ ) By using a sesquicarbonate such as singly or mixed with other carbonates, the solubility is increased and the electrical conductivity is increased to promote electrolysis and increase the generation rate of carbon dioxide gas. In addition, microbubble carbon dioxide gas can be generated by electrolysis in a state exceeding the limit current (current value at which electrolysis efficiency decreases when electrolysis is performed over a certain voltage).

  Moreover, in this Embodiment, in order to add a carbonate efficiently, it adds from the carbonate addition tank 11 arrange | positioned in the middle of the circulation flow path 2, and high concentration carbonate is efficiently bath water 7 The carbonate may be dissolved in the bathtub 1.

  Furthermore, in this embodiment, since the carbon dioxide generator 10 is arranged as a flow path different from the sterilization apparatus 5 by branching the circulation flow path 2, the sterilization apparatus 5 does not affect the generation of chlorine water. A branch valve (not shown) can also be used, but is not particularly necessary, and an adjustable branch valve is provided near the discharge port 22 to exhibit the effect as a throttle valve to discharge a carbonated spring at a predetermined flow rate. It can also be made.

  Furthermore, in the present embodiment, the carbon dioxide generator 10 by electrolysis is integrally disposed in the housing 8 as the electrolyzer 9 together with the sterilizer 5 by electrolysis, and a power source such as the sterilizer 5 or a heater is obtained. Since the power supply device 12 having a large capacity can be used as it is, the same casing 8 as the conventional circulating bath device (24-hour bath) that cannot supply carbonated spring can be used, which is economical. In addition to being small, it does not take up installation space. Also, there is no need for equipment such as carbon dioxide cylinders or pressure vessels, and the usage is simple, just adding carbonate and supplying electricity for electrolysis, especially when you want a carbonated spring such as bathing or showering. It is extremely convenient and economical because it can be used only in an amount.

  In addition, carbon dioxide microbubbles not only make it possible to promote health through the effect of promoting blood circulation as carbonated springs, but also have a bactericidal effect. The safety is further improved by reducing the amount, and there is also an effect of washing the inside of the bathroom, and the effect of the circulating bath device (24-hour bath) can be further enhanced because it becomes difficult to get dirt.

  In the present embodiment, the purification device 3 is of a type in which mineral stones are accumulated, so there is no influence of carbon dioxide contained in the circulating bath water 7, but the purification device 3 is of a microorganism filtration type. When using, the microorganisms used in the bathtub are mostly anaerobic or facultative anaerobic and have little effect. Further, as described above, since the carbonated spring has a cleaning effect, the surface of the heater is prevented from being contaminated and the heating efficiency is prevented from being lowered.

  Next, examples using the embodiment shown in FIGS. 1 and 2 will be described.

  A bath water 7 made of tap water is used in a domestic bathtub 1 having a capacity of 200 [L], the circulation dew 2 is circulated at a predetermined flow rate using a circulation pump 4, and the water temperature is set to 40 ° C. by a heater 6. The carbon dioxide generator 10 (electrolysis tank 103 (see FIG. 3) in the electrolysis apparatus was 150 mm in length and the distance between the electrodes was about 5 mm) was applied with an electrolysis voltage of 24 V and electrolyzed for 1 hour.

  At that time, measurement in Example 1 in which 60 g of carbonate (commercial sodium hydrogen carbonate) was added to the bathtub water 7 in the bathtub 1 and in Example 2 added to the carbonate addition tank 11 provided in the circulation channel 2. The results are shown in Table 1 together with a comparative example in which no carbonate was added.

  According to Table 1, it became clear that Example 1 and 2 became the carbonated spring which has a lot of carbon dioxide gas in the bathtub water 7 in the bathtub 1, and the effectiveness of this invention was proved. The reason why the electrolytic current values are different is that when carbonate is added upstream of the electrolytic cell, the carbonate concentration in the electrolytic cell increases. Moreover, although the pH value was rising in the Example, it returned to the original with progress of time. Furthermore, in the examples, the ORP value (oxidation-reduction potential) turned to-because the chlorine component in tap water disappeared and carbon dioxide gas and hydrogen gas were generated by electrolysis.
