It is desirable that the thickness of the support layer 5 be equal to or larger than the bath sand layer 7, and that each of the bottom pebble layer 5a, the intermediate pebble layer 5b, and the rough sand layer 5c be 100 mm or more. If the support layer 5 is formed in this way, regardless of the particle size and type of the bath sand that forms the bath sand layer 7, the bath sand that forms the bath sand layer 7 will fall to the bottom of the tank 3 or the bottom surface of the tank 3. Outflow from the discharge port portion 15 can be suppressed.

The operation of the sand bath apparatus having such a configuration and the characteristic portion of the present invention will be described. In the bath preparation process, after confirming that there is no user in the sand bath 1,
As shown in FIG. 5, with the vapor supply control valve 45 and the discharge control valves 63, 69, 73 closed, the clean water supply control valve 51 and the chemical liquid supply control valve 57 are opened, and the chemical liquid tank 5
The clean water in which the chemical solution in 3 is charged, that is, clean water containing a medicinal component is supplied from the nozzle 11 of the water supply unit 13 to the tank 3 via the clean water supply pipeline 47 (step 101). At this time, the water level in the level gauge 17 rises according to the water level in the tank 3. In the level meter 17, the water level has reached the position of the sensor installed at the position corresponding to the position where the pipe forming the steam discharge part 9 is immersed, and the water level has reached the position where the steam discharge part 9 is immersed in the tank 3. When it is displayed (step 103), the clean water supply control valve 51 and the chemical liquid feeding control valve 57 are closed, and the water supply to the tank 3 is stopped (step 105).

In this state, the steam supply control valve 45 is opened and the steam is discharged from the steam discharge section 9 into the tank 3 through the steam supply pipe 39 (step 107). At this time, steam is jetted from the steam discharge part 9 toward the bottom surface of the tank 3,
As a result, the clean water containing the medicinal component stored at the bottom of the tank 3 is heated to generate steam containing the medicinal component. Then, the steam containing the medicinal component rises from the bottom of the tank 3, that is, from the support layer 5 toward the bath sand layer 7, whereby the bath sand of the bath sand layer 7 is heated and the heat of the steam causes the support layer 5 and The bath sand layer 7 is sterilized and sterilized, and a medicinal component is deposited on the bath sand of the bath sand layer 7.

After the steam is discharged to the bottom of the tank 3 in step 107, it is confirmed by the thermometer 37 whether the temperature of the boundary portion between the bath sand layer 7 and the support layer 5 reaches 100 ° C. (step 109). . When the temperature of the bath sand layer 7 has reached 100 ° C. in step 109, the steam supply control valve 45 is closed, the supply of steam into the tank 3 is stopped, and it is left as it is for natural heat dissipation (step 111). Then, it is confirmed by the thermometer 37 whether the temperature of the boundary portion between the bath sand layer 7 and the support layer 5 has dropped to 60 ° C to 70 ° C (step 11).
3). At step 113, the bath sand layer 7 is set by the thermometer 37.
When it is confirmed that the temperature of the boundary portion with the support layer 5 has dropped to 60 ° C. to 70 ° C., the bath preparation process is completed and the user starts bathing in the sand bath 1.

After the user starts bathing in the sand bath 1, if the temperature of the bath sand layer 7 used for bathing decreases due to heat radiation, the bath sand layer 7 is dug deeper before bathing. Do so that the bath temperature does not drop.

In this way, when the bathing is performed by the set number of people or when the bath sand layer 7 becomes contaminated, the cleaning process is performed. In the cleaning process, as shown in FIGS. 1 and 5, for example, when a set number of people take a bath (step 2
01), after confirming that there are no users in the sand bath 1,
With the steam supply control valve 45, the chemical liquid injection control valve 57, the discharge control valves 63 and 69 closed and the discharge control valve 73 open, the clean water supply control valve 51 is opened, and the clean water supply pipe line 47 and the water supply unit 13 are opened. The supply of the clean water, which becomes the cleaning liquid, from the nozzle 11 to the tank 3 via the nozzle 11 is started (step 203). Then, the tank 3 is filled with water and the supply of clean water to the tank 3 is continued to overflow the clean water from the tank 3 (step 205). Then, by continuing the overflow state (step 207),
The bath sand layer 7 is agitated, and wastes such as hair and dirt that have accumulated or mixed in the bath sand layer 7 and dirt are removed from the bath sand layer 7, and the bath sand is washed.

At this time, the water supply part 13 is installed on the side wall 23 side forming the long side of the opening of the one tank 3, and the drain groove part 29.
Is provided on the side wall 25 side facing the side wall 23, and the clean water from the nozzle 11 is discharged toward the bottom surface of the tank 3. Therefore, in step 207, if the supply of clean water to the tank 3 is continued and the overflow state is continued, the clean water discharged from the nozzle 11 is discharged toward the bottom surface of the tank 3 and the side wall 23 side is provided on the bottom surface of the tank 3. A flow is formed that spreads from the side wall 25 side to the side wall 25 side through the support layer 5 and the bath sand layer 7 toward the side wall 25 side of the opening of the tank 3. Therefore, the bath sand layer 7 is easily evenly stirred, and the effect of removing waste and dirt such as hair and dirt, that is, the washing efficiency of bath sand can be improved.

In step 207, while the overflow condition is maintained, the overflow water, that is, the degree of contamination of the overflow water is checked (step 209). When it is confirmed in step 209 that the overflow water has been clarified, the clean water supply control valve 51 is closed and the supply of clean water serving as the cleaning liquid is stopped (step 21).
1). After stopping the supply of tap water in step 211, the drain control valves 63 and 69 are opened to drain the water in the tank 3 from the drain port 15 and the level meter drain port 19 (step 213). In addition, the overflow water and the tank 3 discharged in steps 205, 207, and 213
The clean water or the like remaining inside is drained through the drainage tank 61. Further, the hair or the like entrained in the overflow water in steps 205 and 207 is
Captured in. Further, in step 213, since the support layer 5 is formed on the bottom of the tank 3 in this embodiment, the bath sand of the bath sand layer 7 is prevented from flowing out from the discharge port 15 and the level meter discharge port 19. Can be suppressed.

After carrying out such a washing process, the bath preparation process from step 101 to step 113 is repeated to bathe in the sand bath 1.

As described above, in the sand bath apparatus according to the present embodiment, the clean water in which the chemical solution in the chemical solution tank 53 is charged as the liquid suitable for bathing, that is, the clean water containing the medicinal component is supplied to the clean water supply pipeline 47. Through the nozzle 11 of the water supply unit 13 to the tank 3
Is supplied to and stored at the bottom of the bath sand layer 7 by supplying steam from the steam discharge unit 9 to the bottom of the tank 3 through the steam supply pipe 39.
By heating, the bath sand of the bath sand layer 7 can be disinfected and sterilized at the same time as heating of the bath sand layer 7. And the water supply pipeline 4
7. Through the water supply unit 13, clean water serving as a cleaning liquid is supplied from the nozzle 11 to the bottom of the tank 3 to overflow from the tank, and the discharge groove portion 29 is used to overflow the discharge pipeline 71.
By discharging the water through the bath sand layer 7, clean water that becomes a cleaning liquid flows from the bottom of the tank 3 toward the opening. By this flow of clean water, waste and dirt such as hair and dirt accumulated or mixed in the bath sand layer 7 are washed away and discharged from the discharge groove 29 through the discharge pipe 71 for overflow.
