Document Type and Number:
Japanese Patent JP6895102
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a sanitary washing device which can easily identify a cause of failure, in the case where the temperature of the mixed water of hot water and water is not an optimal temperature.SOLUTION: A sanitary washing device includes: a water supply pipe; a hot water supply pipe; a hot water/water mixing device; a nozzle for discharging mixed water of hot water and water; a water drain part for draining the mixed water; a water supply solenoid valve for performing opening/closing of the flow passage of water supply; a hot water supply solenoid valve for performing opening/closing of the flow passage of hot water supply; a switching solenoid valve; a control part; a toilet seat; seating detection means; and temperature measuring means for measuring the temperature of the mixed water. The control part executes: water drain control in which, when seating of a user is detected, the water supply solenoid valve and the hot water supply solenoid valve are brought into an open state, and the switching solenoid valve is switched to a state of flowing the mixed water to the water drain part; and control in which the hot water supply solenoid valve is brough into a closed state in the case where a first temperature of the mixed water is higher than a predetermined range after the water drain control, and in the case where a second temperature of the mixed water after that does not drop from the first temperature, it is determined that water supply is in failure.SELECTED DRAWING: Figure 1
