Sanitary washing device

A sanitary washing device comprising:

• a wash water heating part including a first heater and a second heater, a resistance value of the second heater being higher than a resistance value of the first heater, the wash water heating part heating wash water supplied from a water supply source by only the first heater and the second heater;
• a jetting nozzle jetting the wash water supplied via the wash water heating part;
• and
• a controller controlling a power supplied to the first heater and the second heater,
• the controller performing an energization control to the first heater in a first pattern control and performing an energization control to the second heater in a second pattern control,
• the controller controlling a total power supplied to the first heater and the second heater by the first pattern control and the second pattern control,
• the controller switching energization and non-energization to the first heater in the first pattern control based on a first energization pattern,
• the controller switching energization and non-energization to the second heater in the second pattern control based on a second energization pattern, and
• the controller setting a half-wave of a sine wave of a power source to a half-wave unit, the first energization pattern being configured to combine plurality of the half-wave unit, the second energization pattern being configured to combine plurality of the half-wave unit.
