Field of the Invention The present invention relates to a hot water circulating bath apparatus for circulating hot water in a bath to keep the bath water clear, and more particularly to a hot water circulating bath apparatus for circulating hot water in an electrolytic cell for sterilization.

Cl is ionized to form chlorine ions. When hot water containing chlorine ions flows into the opposite electrode of the electrolytic cell and is energized,
A negative charge is taken from chloride ions to form HClO. HClO has an extremely strong bactericidal activity and effectively sterilizes warm water. For this reason, when the hot water in the bathtub is circulated through the electrolytic bath and energized, the hot water is effectively sterilized.

る。[0003] The applicant of the present application has developed a hot water circulation type apparatus for supplying electricity to circulating water in an electrolytic cell (Japanese Patent Publication No. 87877/1994). As shown in FIG. 1, this hot water circulating device transfers hot water heated by heating means 4 such as a heater from an electrolytic bath 5 to a bathtub 6.
Circulate. This device has the advantage that the voltage between the electrodes of the electrolytic bath 5 can be reduced because hot water heated by a heater or the like is circulated through the electrolytic bath 5. This is because the electrical resistance of water rapidly decreases as the temperature increases. Therefore, the apparatus shown in this figure is characterized in that a sufficient current can be supplied to the circulating hot water by lowering the voltage between the electrodes of the electrolytic cell 5.

循環させる必要がある。However, in the hot water circulation device shown in FIG. 1, since the electrolytic cell 5 and the filtration cell 3 are connected in series, the flow rates of the electrolytic cell 5 and the filtration cell 3 are the same. Filtration tank 3
In order to effectively clarify a large amount of hot water stored in the bathtub 6, it is necessary to increase the circulating flow rate. Filtration tank 3
When the circulating flow rate of the water is low, it is difficult to keep the hot water in the bathtub clear at all times. In particular, when the number of bathers increases and the hot water in the bathtub becomes dirty, clarification cannot be performed quickly. For this reason, it is necessary to circulate as much hot water as possible in the filtration tank 3.

る。[0005] On the other hand, if the circulation flow rate is too large, the electrolytic cell 5 has a property that chlorine ions cannot be efficiently converted into HClO. This is because the time during which the hot water passes between the electrodes of the electrolytic cell 5 becomes short, and the chlorine ions cannot be changed to HClO. In the electrolytic cell 5, when the circulation flow rate is increased and the flow velocity is increased, the generation amount of HClO in the electrolytic cell 5 is reduced, and the sterilization effect of the hot water is reduced. If the circulation amount of the hot water is reduced in order to solve this drawback, the circulation amount of the hot water in the filtration tank 3 is reduced, and the hot water cannot be clarified. If the passage of the electrolytic bath 5 is lengthened in order to increase the time for hot water to pass between the electrodes of the electrolytic bath 5, the electrolytic bath 5 becomes large and the manufacturing cost increases.

This is because the electric resistance between the electrodes is reduced, and a large current can flow at a low voltage. However, reducing the electrode spacing increases the flow rate of hot water passing between the electrodes. This shortens the time for hot water to pass between the electrodes, making it difficult to efficiently convert chloride ions to HClO.

As shown in FIG. 2, the hot water circulation type bathtub apparatus divides an outlet of a heating means 4 such as a heater into two branches, and circulates hot water through an electrolytic tank 5 and a filtration tank 3. In this apparatus, the hot water of the bath 6 is branched and flows to the electrolytic bath 5 and the filtration bath 3, so that the flow rate of the electrolytic bath 5 can be adjusted to an optimum value without considering the flow rate of the filtration bath 3. Therefore, the flow rate of the electrolytic cell 5 can be adjusted to a flow rate at which HClO is efficiently generated.

解槽で効率よく殺菌できなくなる欠点がある。However, the hot water circulation type bathtub apparatus shown in FIG.
Can effectively sterilize the warm water, but when used for a long time, the bactericidal action is reduced. This is because, when used for a long period of time, the flow rate of hot water circulating decreases overall. The flow rate of the electrolytic cell is set at a flow rate that enables the most efficient sterilization, for example, about 5 liter /
Set to minutes. However, when used for a long period of time, calcium and the like contained in warm water are precipitated, and the flow rate is reduced. In particular, the heating means such as a heater, in order to efficiently heat the hot water, in many cases, to increase the flow velocity by narrowing the flow path of the hot water, and calcium and the like that precipitate and grow on the inner surface of the flow path, The flow resistance decreases and the flow rate decreases. When used for a long time, the circulation flow rate of the heater and the like decreases, and the passage resistance of the filtration tank increases. For this reason, the action of the filter tank for clarifying hot water is also reduced. That is, if used for a long time, the flow rate of both the filtration tank and the electrolytic tank decreases,
The hot water in the bathtub has a drawback that it is not kept clear in the filter tank and cannot be sterilized efficiently in the electrolytic tank.

Are connected to the +/− power supply 14. The voltage applied to the electrode 13 is determined in consideration of the flow rate of hot water, the electrode area, and the required current density. For example, the voltage between both electrodes is
The optimum voltage is set in the range of 5 to 100 volts. Electrolyzer 5
Takes a negative charge from chlorine ions (Cl − ) to form HClO. The negative charge taken from chloride ions is proportional to the current between the electrodes. The current between the electrodes is approximately proportional to the voltage. Therefore, the amount of charge taken from chlorine ions can be increased by increasing the voltage between the electrodes.

Preferably does not energize continuously for 24 hours. For example, electricity is supplied to the electrolytic cell at a specific time during which the bath does not take a bath, for example, at midnight, to sterilize hot water in the bath. A hot-water circulation bathtub apparatus that energizes the electrolytic cell at midnight determines the energizing time of the electrolytic cell with a timer. Furthermore, the person who took the last bath can operate the start switch to energize the electrolytic cell for a certain period of time. The hot water circulation type bathtub apparatus that transmits power to the electrolytic cell with a start switch includes a timer that stores the energizing time, and specifies the energizing time with the timer.

A hot-water circulation bathtub apparatus that energizes the electrolytic bath once a day to sterilize hot water in the bathtub can surely sterilize the hot water and effectively prevent bacteria from growing. For this reason, there is a feature that can take a bath sanitarily. Further, when not taking a bath, a device for supplying electricity to the electrolytic cell and sterilizing the bath is provided with hot water for bathing.
The ClO concentration can be reduced. This is because no electricity is supplied to the electrolytic cell when taking a bath. The hot-water circulating bathtub apparatus that can lower the HClO concentration when taking a bath has a feature that the bath can be comfortably taken comfortably, and the hot water can be surely sterilized by increasing the HClO concentration when not taking a bath.

The ejector 17 is disposed such that the tip end portion is narrowed and the tip end portion is extended to a discharge portion of the cheese 16. The hot water flowing from the heating means 4 into the cheese 16 having this structure is accelerated in the cheese 16 and the flow velocity is increased. This is because the flow path area of the portion of the cheese 16 through which the warm water flowing from the heating means 4 passes is narrowed at the tip of the ejector 17. The hot water having a higher flow velocity lowers the water pressure in this portion. Therefore, the warm water discharged from the ejector 17 is drawn to the discharge portion of the cheese 16 whose water pressure is reduced, and can be smoothly discharged.

て、安心して使用できる特長がある。The hot water circulating bath apparatus having the electrolytic cell according to the present invention has a feature that the hot water can be efficiently sterilized even if the hot water flow rate of the heating means or the filter tank is reduced after long-term use. That is, the hot water circulation type bathtub apparatus of the present invention branches the hot water circulation path circulated by the circulation pump into two, connects the electrolytic tank to one branch path, and connects the heating means and the filtration tank to the other branch path. This is because they are connected. The conventional hot water circulation type bathtub apparatus is used for a long time, and when calcium contained in the hot water precipitates on the inner surface of the flow path of the heating means and the flow path of the hot water becomes narrow, the flow rate of both the filtration tank and the electrolytic tank is reduced. And the hot water cannot be efficiently sterilized in the electrolytic cell. In particular, the flow path of the heating means often has a structure in which a thin tube is curved in order to improve heat exchange, which also causes foreign substances to adhere to the flow path of the heating means and reduce the flow rate. ing. On the other hand, the hot-water circulation type bathtub apparatus of the present invention branches the hot-water circulation path circulated by the circulation pump into two sections, one of which has an electrolytic tank and the other has a heating means and a filtration tank. Because of the connection, even if the flow rate of the heating means is reduced after long-term use, the flow rate of hot water circulated through the electrolytic cell is not reduced. Therefore, an optimal amount of hot water is always circulated through the electrolytic cell, and the hot water can be efficiently sterilized in an ideal state. Therefore, the hot water circulating bathtub apparatus of the present invention has a feature that it can be used safely over a long period of time.
