  As raw water supplied to the water quality control device 4, tap water (for example, conductivity 10 to 250 micro S / cm, calcium hardness 20 to 500, water temperature 5 to 30 ° C., about 0.2 MPa) stabilizes the water quality. It is preferable. The raw water is supplied from the outside through the water supply pipe 9 and processed by the water quality control device 4, and then the treated water is supplied from the water supply port 6 of the sauna device 3 through the pipe.

  Further, the hardness component recovered by the water quality control device 4 is discharged from the drainage pipe 10 connected to the water quality control device 4 to the outside of the system. Thereby, it can prevent that a hardness component accumulate | stores inside the sauna apparatus 3, and can maintain water quality stably for a long period of time.

  In addition, it is preferable to put in the control means 5 a sequence that regularly drains stagnant water that has passed for a certain period of time after the treatment, because deterioration of water quality due to propagation of various germs can be prevented.

  A detailed configuration of the sauna device 3 is shown in FIG. The sauna device 3 is configured to be installed in the bathroom 2 so that air in the bathroom 2 can be circulated. A circulation fan 11 for circulating air, a heating means 12 for heating air, and a nozzle 13 for spraying treated water supplied from the water quality control device 4 are provided, and fine water droplets sprayed from the nozzle 13 And heated air are mixed to make high-temperature humidified air and released into the bathroom.

  The heating means 12 is composed of a heat source and a heat radiating section. For example, the heat source may be an electric heater such as PTC or nichrome wire, a copper tube through which hot water is circulated, and the heat radiating section is made of, for example, aluminum. Metal fins such as these are preferable from the viewpoint of heat transfer and workability.

  Further, the nozzle 13 is designed to atomize water and spray it at a constant angle. For example, a nozzle having a nozzle diameter of 0.5 to 1.0 mm and a spraying angle of about 30 to 120 degrees is advantageous in terms of humidification efficiency. To preferred.

  On the other hand, there are several methods for removing hardness components in water, and ion exchange resin method, electrodialysis method, reverse osmosis membrane method, electrodeposition method, etc. are known, and are not limited to any of them. .

  In FIG. 3, the schematic diagram of the water quality control apparatus 4 of an electrodeposition system is shown. The electrodeposition method is to perform electrolysis with an electrode immersed in water, and deposit hardness components such as calcium ions and magnesium ions dissolved in water on the surface of the electrode as insoluble salts such as calcium carbonate and magnesium hydroxide, This is a method for reducing the hardness component of water. It is said that the reaction formula for each polarity is as follows.

Anode: 2OH ⁻ → 1 / 2O ₂ ↑ + H ₂ O + 2e ⁻
Cathode: 2H ⁺ + 2e ⁻ → H ₂ ↑
Mg ²⁺ + 2OH ⁻ → Mg (OH) ₂ ↓
Ca ²⁺ + OH ⁻ + CO ₂ → CaCO ₃ ↓ + H ⁺
To immerse the anode 19 and the cathode 20 in water and further expand the surface area and increase the contact efficiency with water on the cathode 20 side where the hardness component is deposited, for example, the carbon fiber felt 21 is pressed against the cathode 20. Install. The anode 19 and the cathode 20 are materials that can be energized in water. For example, iron, stainless steel, copper, aluminum, brass, titanium, and the like can be used, but titanium is preferable from the viewpoint of durability.

  Furthermore, in order to improve durability, the titanium surface may be coated with platinum or iridium oxide. Reaction efficiency of the electrode can be improved by providing separation means 22 for separating and rectifying bubbles and electrode-reactive organisms generated by the reaction on each electrode between the anode 19 and the cathode 20. . The separation means 22 is preferably a film-like material that is unlikely to become electrical resistance, and for example, a resin mesh such as polypropylene or a membrane can be used. In addition, an ion exchange membrane having ion permeability is preferable because of good separation.

  In order to efficiently treat the treated raw water with an electrode reaction, the treated raw water is preferably passed through the carbon fiber felt 21 that is an electrode so as to uniformly pass through the carbon. The water inlet 23 which arrange | positions the fiber felt 21 and connects the water supply pipe 9 is installed in the upstream of the carbon fiber felt 21. As shown in FIG. In order to prevent the treated water from mixing with the reaction water of the anode 19, a water outlet 25 is provided so that the water can be discharged before the separating means 22.

  On the other hand, since the pH of the reaction water on the anode 19 side is lowered, the reaction water is discharged out of the system from the drain port 27 provided on the anode 19 side. Alternatively, a part may be circulated in the pipe and used for sterilization, or may be used as a regenerating liquid for dissolving the scale deposited on the carbon fiber felt 21.

  The electrode is energized by DC control from the control means 5 to cause an electrode reaction. As the energization condition, it is preferable to use a control circuit that performs constant current control because constant performance can be obtained regardless of voltage fluctuation. The current value is obtained in advance from the water quality and the treatment flow rate so as to ensure the target recovery amount. For example, assuming that the hardness 100 is reduced to 20, when the processing flow rate is 10 mL / min and the current efficiency is 20%, the necessary current value is 0.12A.

  In addition, as for the voltage, it is necessary to examine the necessary voltage from the assumed water quality, electrode area, distance between the electrodes, and the like, and to select an electronic component capable of obtaining a sufficient output and withstand voltage.

  FIG. 4 shows an example of a control flow during operation of the water quality control device 4.

  First, after the sauna operation execution is detected from the user's button operation, a control signal is transmitted from the sauna control means 7 to the control means 5 of the water quality control device 4, and the control means 5 receives and operates the water quality control device 4. Start.

  At this time, the sauna operation mode signal is detected and determined from the control signal, and the processing flow rate is selected. At the same time, the current value setting according to the processing flow rate is also determined. Subsequently, the water supply valve 24 of the water inlet 23 is opened, and after flowing water, energization to the electrode is started and the hardness removal mode is executed. Subsequently, the supply valve 26 of the water outlet 25 is opened to supply water from which hardness has been removed to the sauna device 3.

  In the sauna operation, when the timer control or the stop operation is executed, it is determined that the operation is stopped, a stop signal is transmitted from the sauna control means 7 to the control means 5, and the control means 5 closes the supply valve 26 to the electrode. Stop energizing. After that, if the operation start signal is not received within a predetermined time, it is determined that the use of the device is stopped, and the regeneration mode for discharging the collected hardness component is entered.

  In the regeneration mode, the polarity is reversed to that of the hardness removal mode, and a direct current is applied to dissolve and peel the scale attached by the electrode reaction. Subsequently, the drain valve 28 of the drain port 27 is opened, and the peeled scale and electrolyte are drained out of the system. After passing water for a predetermined time, reverse energization is stopped, all valves are closed, and operation is stopped. In order to ensure performance, it is preferable to display that the regeneration mode is being executed on the display means so that the user does not stop the regeneration operation while the regeneration mode is being executed.

  Further, the total time of all energization times is stored in a storage device provided in the control means 5 and displayed on the display means when the user requests the display by remote control operation, or a preset tolerance is set. When it is determined that the usage time has been exceeded, it is preferable to provide a determination control in which the display means notifies the user to perform maintenance, because this leads to reliable performance maintenance.

  In the first embodiment, the electrodeposition method is used for the water quality control device 4. However, an ion exchange resin method or an electrodialysis method may be used instead of the electrodeposition method. It is preferable because it does not require replenishment and is inexpensive and has a configuration that facilitates fine operation control.

  Since the sauna system according to the present invention can stably remove the hardness component of water used for sauna operation, the scale failure prevention of the sauna device used in the bathroom and the operation of the water quality control device are performed. This is useful for improving control efficiency.
