Etc. adhere to the surface of the cathode, the CO 2 dissolution efficiency gradually decreases. In particular, when a carbonaceous electrode is also used as the cathode, since there are many open pores, the adhesive force is extremely stronger than that of a metallic electrode such as stainless steel. Further, when the attached matter is physically removed, the electrode may be broken. Therefore, the device of the second invention will be described with reference to the reference numerals of FIG. 3. In the water electrolysis electrode 1, the anode 1a and the cathode 1b are composed of carbonaceous electrodes, and the means 10 for switching the polarity is interposed therebetween. are doing.

り一層の長寿命化を図ることができる。The electrical resistivity ρ of the carbonaceous electrode conventionally used as an electrode for electrolysis is 1 × 10 −3 Ω · c.
It is about m, which is considerably larger than metals such as copper (ρ = 1.7 × 10 −6 Ω · cm) and iron (ρ = 9.7 × 10 −6 Ω · cm). Ohmic loss is also larger than that of metallic electrodes. Furthermore, due to the resistance of the electrodes themselves,
As the distance from the current introducing portion of the electrode increases, the amount of voltage drop in the electrode increases to a non-negligible level, resulting in non-uniform current density between the anode and the cathode. Therefore, when the anode and the cathode are arranged in parallel, the electrodes are consumed unevenly and it is difficult to extend the life. Therefore, the device of the third invention is
Explaining with reference to FIG. 4, the anode 1a and the cathode 1b
Is a water electrolysis electrode 1 composed of a carbonaceous electrode, and the anode 1a and the cathode 1b thereof are formed into a plate shape, and a plate-like anode is formed as the water electrolysis electrode 1 is separated from the current introducing portions 11a and 11b. It is arranged so that the surface spacing to the plate cathode gradually becomes smaller. By doing so, the current density between the electrodes can be made constant, the electrodes can be consumed uniformly, and the life can be further extended.

When it is used for at least the anode 1a, the efficiency of CO 2 dissolution increases, and it also acts as a long-life electrode, so it is suitable as a carbonaceous electrode for the bath water heaters of the first to third inventions. The reason is described below.

とが困難であった。The carbonaceous electrode which has been conventionally used as an electrode for water electrolysis is obtained by mixing petroleum coke or coal coke as an aggregate and mixing coal tar pitch with a binder, molding, firing and graphitizing. The graphite material used was used. When such a carbonaceous electrode is used as an anode and bath water is electrolyzed, anodic oxidation occurs not only on the electrode surface but also in the pores, a large amount of carbon particles fall off, and the bath water turns black in a short time. . In addition, when electrolysis is performed using glassy carbon prepared from thermosetting resin with almost no pores as an anode, pit oxidation-like anodic oxidation occurs, peeling occurs on the electrode surface, and finally it breaks and electrolysis is impossible. Will fall into. As described above, the ordinary carbonaceous electrode has a relatively short life, and it is difficult to sufficiently exhibit its ability.

るからである。The reason why the present electrode is optimal will be described in more detail below. In order to be an electrode suitable for preparing CO 2 bath water,
In addition to the requirement of high CO 2 dissolution efficiency, the condition that the bath water is not contaminated is required. In particular, the present invention is applied to a bath water heater of the type that circulates the bath water in the bathtub, so the latter condition is strongly required. Therefore, JP-A-7-432
As demonstrated in Japanese Patent Publication No. 80, the CO 2 dissolution efficiency is extremely high, and the number of carbon particles desorbed from the surface is small.
Carbonaceous material 50 to 90% by mass and resin cured product 10 to 5
A carbonaceous electrode consisting of a composition with 0% by weight is used. When it is out of this range, carbon particles may be detached from the surface of the carbonaceous electrode to contaminate the bath water, which is not preferable. Further, if it is out of this range, the CO 2 dissolution efficiency is also lowered.

介して水電解用電極に接続した方が好ましい。As a method for preparing a CO 2 bath using a carbonaceous electrode, one of the anode and the cathode is a water electrolysis electrode in which at least the anode is composed of a carbonaceous electrode, and a bath in the middle of the bath bath circulation system is used. CO 2 may be prepared by electrolyzing hot water. The electrolysis voltage at this time depends on the distance between the electrodes, the amount of impurities contained in the bath water, etc. and cannot be uniquely determined, but when electrolyzing the bath water of tap water, the distance between the electrodes is usually If it is 5 to 10 mm, electrolysis can be performed if the voltage is 5 V or more. Here, in the case of the present electrode, it is preferable to perform electrolysis under the condition that the value (current density) obtained by dividing the total current by the operating area is 10 mA / cm 2 or less. The reason is that if the current density exceeds 10 mA / cm 2 , the electrode surface may be roughened, and the electrolysis efficiency may be deteriorated or the life may be shortened. In the electrolysis method, a carbonaceous electrode is used at least as an anode of the anode or the cathode, and the carbonaceous electrode is partially or wholly immersed in bath water in the bath hot water circulation system and electrolyzed at direct current. In addition to the carbonaceous electrode, a metal electrode such as stainless steel can be used as the cathode. Of course, electrolysis may be performed by alternating current, but since the electrolysis efficiency decreases, when an alternating current power source is used, the electrode for water electrolysis is connected between the power source and the electrode for water electrolysis through an ac-dc converter. It is preferable to connect them.
