An apparatus for protecting a circuit in a bidet is provided to protect a microcomputer and a driving circuit of a bidet by cutting off a power irrespective of a condition and an environment when a malfunction is detected. An apparatus for protecting a circuit in a bidet includes a malfunction detection unit(11), a first switching element(Q1), at least one driving control switching element(Q2-Q3), and at least one microcomputer control switching element(Q4-Q10). The malfunction detection unit detects a malfunction of a microcomputer from a signal outputted from the microcomputer. The first switching element has a first terminal for receiving a constant voltage, and a control terminal for receiving a control signal from the malfunction detection unit. The driving control switching unit has a first terminal, a control terminal and a second terminal. The first terminal is connected to a second terminal of the first switching element. The control terminal receives a control signal. The second terminal is connected to a driving unit. The microcomputer control switching element has a first terminal, a control terminal and a second terminal. The first terminal is coupled to the second terminal of the first switching element. The control terminal receives the control signal. The second terminal is coupled to the microcomputer. |
