PURPOSE: An instant hot water device for washing a bidet is provided to smoothly supply fluid by reducing flow-resistance of the fluid flowing in a spiral flow passage. CONSTITUTION: An instant hot water device for washing a bidet comprises a spiral flow passage(200), ribs(300), and a heater. The spiral flow passage communicates an inlet(110) and an outlet(120) of a housing(100). The ribs change a flow of fluid flowing in the spiral flow passage so that the fluid is supplied. The heater heat-exchanges the fluid. |
