PURPOSE:To prevent assuredly a sucking accident which occurs at the time when a protection cover is taken off. CONSTITUTION:The bath unit is provided with a bath water discharge section 8 to draw the surface water in the bathtub together with floating dusts and a bath water purification section 6 to filter the drawn out bath water and to flow the filtered water back to the bathtub. When a protection cover detective sensor 40 detects the removal of the protection cover 38 covering the bath water discharge section 8, a control section 9 suspends the circulation of the bath water by the bath water purification section 6. |
