PROBLEM TO BE SOLVED: To control temperature/water level in running water-type bathtub efficiently, which is conventionally difficult. SOLUTION: A temperature sensor and a water level sensor are installed in a bathtub. Opening and closing of an inlet valve of the hot spring water/cold water is controlled through the signal from the sensor. Additionally, since a supplying port of water is positioned above the bathtub, an outlet port is provided in the lower part of the bathtub so that temperature in the bathtub may be maintained evenly. A drainage is provided at the lower part of the bathtub. By using this method, proper temperature and water level can be maintained, and comfortable bating is enabled. COPYRIGHT: (C)2008,JPO&INPIT
