<p>PROBLEM TO BE SOLVED: To provide a sanitary washing device that is easy to use by improving precision of water level detection and expanding a use range of washing water.SOLUTION: A sanitary washing device includes a nozzle device 800, a water pump 516, a heat exchanger 700, a sub-tank 600 arranged upstream from the heat exchanger 700, and a control part 130. The sub-tank 600 includes a water level detection sensor 620 which detects a water level and an incurrent water temperature sensor 630, and the water level detection sensor 620 includes a common electrode 621 and a plurality of water level electrodes 622, and is configured to detect the water level from variation in voltage when a DC current is applied between the common electrode 621 and water level electrodes 622. The control part 130 has a threshold for determining water immersion states and water non-immersion states of the water level electrodes 622, and corrects the threshold according to temperature detection data of the incurrent water temperature sensor 630. Consequently, the sanitary washing device can improve precision of water level detection and also can use washing water varying in electric conductivity over a wide range, and is thereby wide in use range and easy to use.</p> |
