Abstract: A sanitary washing device includes a nozzle, a heat exchanger, a cold water flow channel, a switching element, a control board, a heat transfer plate, and a casing. The heat exchanger uses alternating current power to heat the wash water supplied to the nozzle. The cold water flow channel supplies the wash water to the heat exchanger from a water supply source. The switching element switches a supply state of the alternating current power to the heat exchanger. A controller is mounted to the control board. The controller is operated by direct current power. The controller controls the switching element. The heat transfer plate is configured to dissipate heat of the switching element. The switching element is mounted to the control board. The cold water flow channel includes a cooling part. The cooling part water-cools the heat transfer plate.

Abstract: A sanitary washing device includes a nozzle, a valve unit, a casing, a water supply hose, and a water supply connection part. The nozzle is configured to discharge water toward an ano-genital region. The valve unit is provided on a pipe line between a water supply source and the nozzle. The valve unit includes an electromagnetic valve. The water supply hose is configured to supply water from the water supply source into the casing. The water supply hose is flexible. The water supply connection part connects the water supply hose and the valve unit. The casing has a concave portion recessed upward from a bottom surface of the casing. The concave portion has an upper surface and a side surface extending from the upper surface and facing backward or sideward. The water supply connection part is provided on the side surface of the concave portion.

Abstract: A sanitary washing device includes a nozzle, a valve unit, a casing, and a toilet seat. The nozzle is configured to discharge water toward an ano-genital region of a human body. The valve unit is provided on a pipe line between a water supply source and the nozzle, and includes an electromagnetic valve. The casing stores the nozzle and the valve unit. The casing includes a low portion positioned below the toilet, and a high portion positioned backward of the low portion. A length in a vertical direction of the high portion is greater than a length in the vertical direction of the low portion. The valve unit is disposed in the low portion. A length in the vertical direction of the valve unit is less than a length in a longitudinal direction, and less than a length in a lateral direction.
