  Next, the relationship between excess humidified water temperature and bathroom humidity will be described with reference to FIG.

  As shown in FIG. 4, the surplus humidified water temperature G001 gradually increases in the same manner as the bathroom temperature G002 from the start of the sauna operation. The dew point temperature of the air in the bathroom 2 becomes a dew point temperature G004 as shown in the figure from the humidity G003 in the bathroom 2 and the temperature G002 in the bathroom 2. Here, the surplus humidified water temperature G001 is close to the wet bulb temperature due to the heat of vaporization caused by the evaporation of water using the principle of the wet and wet bulb hygrometer, and thus has a correlation with the dew point temperature G004. If the internal temperature G002 can be detected, the internal humidity G003 in the bathroom 2 can be known.

The humidifying water temperature G001 is 38 ° C. In order to detect a state where the inside of the bathroom 2 exceeds a predetermined value, it is only necessary to detect the time when the bathroom 2 temperature is 40 ° C. or higher and the excess humidified water temperature is 38 ° C. or higher. The predetermined value required for the sauna can be determined from the temperature detected by the means 9 and the excess humidified water temperature detecting means 11.

  As shown in FIG. 6, in step S018 after starting the sauna operation, from the bathroom temperature T1 detected by the bathroom temperature detecting means 9 and the excess humidified water temperature T2 detected by the excess humidified water temperature detecting means 11, the step is performed. In S019, differences ΔT1 and ΔT2 from predetermined values (predetermined bathroom temperature predetermined value TS1 and excess humidified water temperature predetermined value TS2) are calculated. In step S020, after a fixed time timer S1 has elapsed, in step S021, The internal temperature T10 and the excess humidified water temperature T20 are detected. In step S022, the time until the difference ΔT1, ΔT2 with respect to the predetermined value becomes 0 is calculated from T1, T10, S1, and the excess humidified water temperature is calculated from T2, T20, S1. The calculation result is used as the time until preparation is completed, and is displayed on the remote controller. The calculation is repeated until the preparation completion time becomes 0 or less, and the calculation accuracy is gradually increased by displaying the result. For example, the predetermined values are the bathroom temperature TS1 = 40 ° C., the excess humidified water temperature TS2 = 38 ° C., the detected bathroom temperature T1 is 30 ° C., the excess humidified water temperature T2 is 28 ° C., and the timer S1 is set to 1 for a certain time. Assuming that the temperature T10 in the bathroom 2 after a certain period of time is 31 ° C. and the excess humidified water temperature T20 is 30 ° C., the temperature arrival time TI1 in the bathroom 2 up to a predetermined value is TI1 = (TS1-T1) / (( T10−T1) / S1) = (40−30) / ((31−30) / 1) = 10 minutes. Similarly, the surplus humidified water temperature arrival time TI2 up to a predetermined value is TI2 = (TS2−T2) / ((T20−T2) / S1) = (38−28) / ((30−28) / 1) = 5 minutes. Here, for convenience, the longer of TI1 and TI2 is displayed as the preparation completion time, but the target air is calculated by calculating the enthalpy of air from the temperature in the bathroom 2 and the excess humidified water temperature and setting the predetermined value as the target air enthalpy. By calculating the difference from the enthalpy, the target air enthalpy can be kept constant even if the temperature and humidity in the bathroom 2 vary greatly, so that the prediction accuracy until reaching can be further increased.

  Next, a control process for transmitting the degree of achievement until completion of sauna preparation will be described with reference to the flowchart of FIG.

In step S027, the achievement level is divided. The calculation result is the degree of achievement until the completion of preparation, and is displayed on the remote controller or the like in step S028. In step S029, the calculation is repeated until the achievement reaches 1 or more, and the result is displayed. For example, assuming that the predetermined values are the bathroom temperature TS1 = 40 ° C., the excess humidified water temperature TS2 = 38 ° C., the detected bathroom temperature T1 is 30 ° C., and the excess humidified water temperature T2 is 28 ° C., the bathroom up to the predetermined value. The internal temperature reach TT1 is TT1 = TS1-T1 = 40-30 = 10, and the surplus humidified water temperature reach TT2 up to a predetermined value is TT2 = TS2-T2 = 38-28 = 10. In order to replace the calculation result with the achievement level, from the experimental result and the like, 1 to 2, 1 to 4 is 0.95 to 6 is 0.8. . . . It may be defined by, for example. In addition, for the sake of convenience, the smaller of TT1 and TT2 is displayed as the degree of achievement, but by calculating the enthalpy of air from the bathroom temperature and excess humidified water temperature and setting the predetermined value as the target air enthalpy, the target air enthalpy and By calculating the difference, the target air enthalpy can be kept constant even when the bathroom temperature and humidity fluctuate greatly, so that the prediction accuracy until reaching can be further improved.

In S031, differences ΔT1 and ΔT2 with predetermined values (predetermined bathroom temperature predetermined value TS1 and excess humidified water temperature predetermined value TS2) are calculated. In Step S032, the differences ΔT1 and ΔT2 with the predetermined values are 5 or more. In step S033, the direct humidifying means 4a and the fine water droplet humidifying means 4b are operated in combination. When the number is 5 or less, the fine water droplet humidifying means is operated alone in step S034. In step S035, the above flow is repeated until the sauna operation is completed. Here, for the sake of convenience, the larger one of ΔT1 and ΔT2 is taken in as the determination of the differences ΔT1 and ΔT2, but the target enthalpy is calculated by calculating the enthalpy of air from the bathroom temperature and the excess humidified water temperature and setting the predetermined value as the target air enthalpy. By calculating the difference from the air enthalpy, the target air enthalpy can be kept constant even if the bathroom temperature and humidity fluctuate greatly, so that the accuracy of switching can be further improved. Further, although the difference from the predetermined value of the switching standard in step S032 is set to 5, it may be arbitrarily set according to the user's preference.
