Title:
BATH DEVICE
Document Type and Number:
Japanese Patent JP2011169529
Kind Code:
A
Abstract:

To provide a bath device capable of correctly calculating an amount of hot water remaining in the bath tub though the bath device includes an automatic flow passage switching means for automatically switching flow passages according to temperature.

The bath device 1 has a circulation flow passage 21 going from a hot water suction port 47 to a hot water discharge port 45, a bubble mixing flow passage 49 diverging from the circulation flow passage 21 and going to a bubble mixing hot water discharge port 46, and the automatic flow passage switch 55 for automatically switching the flow passages going to the hot water discharge port 45 or to the bubble mixing hot water discharge port 46 according to the temperature of the hot water. Further, the bath device 1 includes a remaining hot water calculation function for calculating the amount R of the hot water remaining in the bathtub 5. For obtaining data considered for the remaining hot water calculation function, hot water at temperature higher than predetermined temperature is made to pass in the circulation flow passage 21 prior to execution of the remaining hot water calculation function. By this, the flow passages of hot water are fixed to one side, which improves reliability of the data and allows calculation of the correct amount R of the remaining hot water.
