And the blower 9 was driven, and warm air was supplied from the rear of the human body as shown by arrow A to dry the anus.

[0005]

However, in the conventional hot-air drying configuration, the water droplets after washing the anus are attached to the body behind the buttocks with respect to the state in which they adhere to the skin around the anus. It is a method of drying by applying warm air of about 40 ° C blown out from the air duct, but warm air is blown out from a fixed position behind the buttocks in the sitting position and strokes the buttocks surface as shown by arrow A. Since it does not directly contact the flow anus, it takes a very long time to dry the adhered water, and there is a problem that the user feels irritated and suffers from the monotonous feeling during use. In addition, since the temperature of the skin is increased and the moisture is evaporated to dry the skin with a large amount of water remaining on the skin surface, the skin may be overdried, causing itching and rashes on the skin.

The present invention solves the conventional problems.
