At the same time, the buttocks temperature detected by the buttocks temperature detection sensor 6 is captured (step S3), and the detected buttocks temperature T is compared with a set value T ₀ (set to 38 ° C. in this example) ( Step S4).

Initially, since the buttocks temperature does not reach the set value, the heater 4 is activated here (step S).
5) Warm air is blown from the outlet 5. Steps S1 to S4 are repeatedly performed as needed. At this time, since the buttocks are generally in a wet state, the surface temperature of the buttocks does not reach the measured value T ₀ even if the temperature of the blown hot air is high.

Now, the surface temperature of the buttocks gradually rises due to the blowing of warm air, and when the temperature reaches the set value T ₀ , the heater 4 is turned off (steps S 4 and S 6).
Air that is not heated by the heater 4 is blown from the outlet 5.

At this point, the rise in the temperature of the buttocks surface is interrupted, and the temperature temporarily drops slightly due to the action of the blown air or the like.
Then, the heater 4 is turned on again (steps S4 and S4).
5) Increase the temperature of the blown air. Thereafter, these operations are repeated to finish the drying. When the user operates the operation switch 2 again (step S1) to turn it off, the fan 3 and the heater 4 are turned off (step S7), and the buttocks drying device 8 stops operating.

As described above, according to the present embodiment, since the temperature of the buttocks can be kept constant, the drying can be completed in a short time without feeling the heat of the buttocks.

FIG. 4 shows another embodiment of the present invention. In this embodiment, a light emitting portion 9 for emitting various colors is arranged on the overhang portion 1b of the toilet seat box 1A, and the buttock temperature sensing is performed. Light of a color corresponding to the temperature detected by the sensor temperature detection sensor 6 is emitted. The light emitting unit 9 can be composed of, for example, a plurality of light emitting diodes that emit different colors.

In this embodiment, the control section 7 controls the light emission of the light emitting section 9 and emits light of a color corresponding to the temperature detected by the buttocks temperature detecting sensor, that is, the temperature of the buttocks, to thereby control the buttocks temperature. As the color rises, for example, blue → yellow →
It is changed to red.

In the case of this embodiment, until the drying is completed, it is possible to recognize the rise in the temperature of the buttocks and the progress of the drying by the color change, thereby eliminating the frustration of the time until the drying is completed. can do.
