Next, the adjacent indoor remote controller 13 shown in FIG. 4 is provided with a timer time setting dial 40 for setting a timer time, and below it, a sauna switch 41 and a hot water heating switch 42 are arranged. It is installed and configured.

First, the mist sauna operation in the mist sauna device having such a structure will be described. In the mist sauna operation, hot water is sprayed in the form of mist from the mist sauna nozzles 1, 1, 1 to use the bathroom as a sauna room. The operation control by the controller 11 will be described with reference to the flowcharts of FIGS.
In step S1 of, the user operates the remote controller 12 in the bathroom.
By turning on the sauna switch 34 of, or by turning on the sauna switch 41 of the adjacent indoor remote controller 13,
In step S2, the sauna operation LED of the remote controller 12 in the bathroom and the sauna set temperature display of the display unit 32 are turned on.

Then, in step S3, the controller 11 turns on the flowing water solenoid valve 7 to open the flowing water solenoid valve 7.
As a result, water is sprayed from the hot water heating nozzle 9 onto the floor surface 31 of the bathroom.
3, the initial cold water remaining in the hot water pipe 25 and the vertical pipe 27, and the initial cold water in the pipe line is supplied to the hot water heating nozzle 9
It is configured to prevent the initial cold water from being sprayed from the mist sauna nozzle 1 and lowering the room temperature in the bathroom by discharging the cold water onto the floor surface 31.

In step S4, the room temperature in the bathroom is 30 ° C. based on the detection signal from the room temperature detection thermistor 15.
It is determined whether or not the above is reached, and it is determined whether or not the initial cold water has all been discharged and the hot water generated by the hot water supply device 16 has begun to be discharged from the running water heating nozzle 9. Further, in step S5, it is determined whether or not hot water of 50 ° C. or higher has reached the hot water pipe 25 from the hot water supply device 16 based on the detection signal from the hot water temperature detection thermistor 8.

After confirming that all the initial cold water has been discharged and the hot water generated from the hot water supply device 16 has arrived, in step S6, the solenoid valve 7 for flowing hot water is turned off and closed, and In step S7, the solenoid valve 2 for the sauna is turned on to open the mist sauna nozzle 1
Spray hot water from. As a result, the room temperature rises in the bathroom due to the sprayed hot water. This room temperature detection thermistor 15 detects the rise in room temperature and determines in step S8 whether or not the room temperature has reached the set temperature. . When the room temperature reaches the set temperature, the preparation completion buzzer is turned on and the sauna timer setting display is displayed on the display unit 32 in step S9 of FIG. This display 32
The timer set time displayed on the display indicates the remaining time, and the sauna timer countdown is started in step S10.

Next, the motor 4M of the mist hot water temperature adjusting electric valve 4 is controlled to adjust the mixing amount of hot water, and the hot water temperature ejected from the mist sauna nozzle 1 is controlled in step S11. As a result, the room temperature gradually converges to the set temperature. In step S12, it is determined whether or not the room temperature has converged to the set temperature based on the detection signal from the room temperature detection thermistor 15. In step S13, the room temperature is set to the set temperature. It is further determined whether or not the temperature exceeds + -2 ° C., and the room temperature is maintained at the set temperature. After the room temperature converges to a constant value at the set temperature, it is determined in step S14 whether or not the timer set time has expired. For example, when the timer time is set to 10 to 15 minutes, ,
After the time has ended, in step S15, the LED for sauna operation, the sauna setting display and the sauna timer display are turned off, the solenoid valve 2 for the sauna is turned off and closed, and the ejection from the mist sauna nozzle 1 is stopped.

In this way, by spraying high-temperature hot water from the mist sauna nozzle 1 for a certain period of time to transform the inside of the bathroom into a sauna room, the bathroom can be used as a sauna. In this example, initial cold water is used. Since it is discharged from the hot water heating nozzle 9 to the floor surface 31 of the bathroom prior to the sauna operation, the mist sauna nozzle 1 does not suddenly spout the initial cold water and the room temperature does not drop, so that it can be well operated during the sauna operation. The room temperature can be quickly raised.

That is, as shown in FIG. 7, in this example, the temperature a in the bathroom does not drop at the hatched position d at the initial stage, and the hot water discharged from the hot water heating nozzle 9 is discharged. After the temperature c rises, the mist sauna nozzle 1 shown by b
Since the mist sauna operation is performed by spraying from
It is possible to quickly raise the temperature in the bathroom to a predetermined temperature without lowering it initially.

Incidentally, FIG. 8 shows a comparative example in which a conventional initial cold water is jetted from the mist sauna nozzle 1 to perform a sauna operation. In FIG. Since the initial cold water is ejected, the room temperature drops within the cold water spraying time T.

Here, the water purifier 14 shown in FIG.
The dechlorinating agent such as calcium sulfite is enclosed in the water purifier 14, and when the dechlorinating agent is calcium sulfite, this calcium sulfite reduces chlorate ions in hot water. , Such as calcium sulfate, which can remove chlorine. Such a water purifier 1
When 4 is not provided, the chlorine gas in the hot water is diffused into the bathroom by the hot water sprayed from the mist sauna nozzle 1 through the nozzle tube 1A, and the bathroom is filled with the chlorine gas, This chlorine gas reduces the amount of oxygen supplied to the lungs of the human body, and chlorine gas reacts with sebum on the skin of the human body to form chlorine compounds, which are absorbed by the body,
Although chlorine gas has an adverse effect on the body, in this example, the water purifier 1 in which the dechlorinating agent is enclosed in this way
Since 4 is provided, it is possible to suppress the generation of chlorine gas satisfactorily and prevent the harmful effects of chlorine gas satisfactorily. A comfortable bathing in the bathtub 30 and a mist sauna nozzle 1 in which the mist is spouted Will be able to do. The dechlorinating agent of the water purifier 14 is preferably configured as a detachable cartridge type or the like so that it can be replaced at predetermined intervals.

The water purifier 14 is a nozzle tube 1A in this example.
However, the water purifier 14 may be provided in other pipelines, or a plurality of water purifiers may be provided in each pipeline.

Next, the cool down operation will be described with reference to FIG. That is, conventionally, as shown in FIG. 11, as described above, the mist sauna nozzle 1 is sprayed to perform the sauna operation, and the sauna operation is performed at a predetermined time.
When stopped at e in 1), the temperature a in the bathroom does not drop immediately, but only heat is released by opening the door of the bathroom, so the temperature does not drop easily and the sauna user does not drop the temperature. Often, you use a cold bath or cold water shower, and when you are in the sauna, your heart rate increases at the same time as sweating, and your blood pressure falls. However, since the heart rate does not decrease suddenly, the heart is extremely burdened, which causes an unfavorable situation for health. As shown in FIG. 10, after running the sauna, cold water is discharged from the mist sauna nozzle 1. This cool-down operation control is installed so that the temperature in the bathroom can be lowered appropriately by spraying and the burden on the mind and body of the sauna user can be reduced. Such a cool-down operation is not possible with a steam-type jet sauna, but in this example, the mist sauna nozzle 1 sprays hot water. By lowering the temperature of the hot water spouted from No. 1, the room temperature lowering function can be satisfactorily exhibited.

This cool-down operation control will be described with reference to FIG. 9. The cool-down switch 35 of the bathroom remote controller 12 is described.
When the user turns on in step S20, the LEDs of the set temperature display and the timer display of the display unit 32 are turned on in step S21. Next, the controller 11 controls the motor 4M of the mist hot water temperature adjusting electric valve 4 in step S22 to cause the mist hot water temperature adjusting electric valve 4 to operate.
Is set to the lowest mixing ratio. Next, step S
At 23, the solenoid valve 2 for the sauna is turned on and opened, and cold water is sprayed from the mist sauna nozzle 1. Step S
At 24, the room temperature, the set temperature, and the gradient of the room temperature decrease are determined from the timer settings, and the mist hot water temperature adjusting electric valve 4 is adjusted. As a result, as shown in FIG.
Is low, so the room temperature a in the bathroom gradually decreases,
In step S25, it is determined from the detection signal from the room temperature detection thermistor 15 whether or not the room temperature has reached a set temperature, for example, about 25 ° C. If the set temperature has not been reached, it is determined in step S26 whether or not the set time has expired. If not, cold water is further spouted from the mist sauna nozzle 1 to lower the room temperature. When the room temperature reaches the set temperature, step S
At 27, control the mist hot water temperature control electric valve 4,
As shown in FIG. 10, the room temperature a is converged to a constant temperature. In step S28, it is determined whether or not the room temperature has converged at a constant temperature, and further in step S29, it is determined whether or not the room temperature is within the set temperature + -2 ° C. to allow the room temperature to converge well, and then step S30. In step S31, it is determined whether or not the set time is up, and when the time is up, the LED of the display unit 32 is displayed.
Is turned off, the solenoid valve 2 for the sauna is turned off and closed, and displays such as temperature display and timer display are also turned off.

In this way, after the sauna operation is finished, the cool-down operation controlled by the flowchart of FIG. 9 is put in, and the temperature in the bathroom is lowered well, so that the sauna user can use the water bath or the water shower as in the conventional case. It is possible to cool the body satisfactorily in a state where the burden on the body is reduced without using the to cool the body rapidly.

Next, in the flow chart of FIG.
The mist cooling operation will be described. That is, this mist cooling operation eliminates a state in which the room temperature in the bathroom is extremely high and uncomfortable during bathing in the summer, and lowers the room temperature in the bathroom to control a comfortable bathing environment in the summer. Spray cold water from the mist sauna nozzle 1,
It aims to cool the bathroom simply by absorbing the heat in the bathroom with sprayed cold water.

That is, in FIG. 12, when the user turns on the mist cooling switch 37 of the remote controller 12 in the bathroom in step S40, the LE of the set temperature display and the timer display of the display unit 32 is displayed in step S41.
D is displayed, and in step S42, the controller 11 controls the motor 4M of the mist hot water temperature adjusting electric valve 4 so that the mixing ratio of the mist hot water temperature adjusting electric valve 4 becomes the coldest temperature. In step S43, the solenoid valve 2 for the sauna is turned on and opened, so that cold water is sprayed from the mist sauna nozzle 1, and the temperature of the bathroom gradually decreases due to the spray of cold water. , Room temperature is the set temperature,
For example, it is determined whether or not the temperature has reached about 25 ° C., and if it has not reached, the spray of cold water from the mist sauna nozzle 1 is continued until the set time is up in step S45. When the room temperature reaches the set temperature, step S4
At 6, the mist hot water temperature control electric valve 4 is controlled to converge the room temperature to the set temperature. In step S47, it is determined whether or not the room temperature has converged to the set temperature.
At 48, it is determined whether the temperature is within the set temperature + -2 ° C., and if the room temperature does not converge to the predetermined value, the mist hot water temperature adjusting electric valve 4 is further controlled to converge the room temperature. After the room temperature converges to the set temperature, it is determined in step S49 whether or not the set time has timed up. After the timed up, in step S50, the solenoid valve 2 for the sauna is turned off and closed, and the mist sauna nozzle 1 Stop spraying, LE of temperature display and timer display of the display unit 32
Turn off D and end.

As described above, by effectively using the mist sauna nozzle 1, cold water can be sprayed from the mist sauna nozzle 1 to easily cool the bathroom in the summer, and the temperature in the bathroom can be lowered to be comfortable. It is possible to prepare a perfect bathing environment.

Next, the control of the hot water heating operation will be described with reference to FIG. This running water heating operation causes the bath floor to be cold and uncomfortable when taking a bath, especially in winter,
This is done in order to properly heat the floor of the bathroom in advance and to raise the temperature in the bathroom to a good temperature before taking a bath. That is, in FIG. 13, when the running water heating switch is turned on in step S60, that is, in this case, the running water heating switch 42 of the adjacent indoor remote controller 13 installed in the dressing room shown in FIG. 4 is turned on.
