にしている。2. Description of the Related Art A conventional technique of a sanitary washing device will be described below with reference to the drawings. FIG. 2 is a view showing the whole of the sanitary washing apparatus, in which 1 is a sanitary washing apparatus main body (a washing section for washing a local part of a human body, a hot water section for boiling the washing water, and a drying section for a wet local part after washing). 2 is a toilet seat, 3 is a toilet lid, 4 is an operation unit (constituted of a plurality of switches), and the toilet seat 2 has a seating detection unit. (Not shown), and basically enables the operation from the operation unit 4 only when the seating of the human body is detected.

This signal is processed, and an output signal is output to the main unit 1 so as to perform an operation according to the switch operated by the operation unit 4. Therefore, when the human body is not sitting, the control unit 6 operates the operation unit 4.
Since no signal is received from the control unit 4, no malfunction occurs even if a signal enters the control unit from the operation unit 4 due to noise or the like.

て、用便等を行なえないという不具合が生じる。Problems to be Solved by the Invention By the way, the conventional sanitary washing device detects a seat when a person sits on a toilet seat when a switch of the operation unit 4 is in a short state due to dew condensation or a short circuit occurs. Since the section detects the seating, the main body performs an operation corresponding to the switch in the short state at that moment. For example, if the switch of the washing function is short-circuited, the washing water jumps out at the moment when the person sits on the toilet seat, and the washing water does not stop until the person stands up. Therefore, there arises a problem that it is impossible to perform a service or the like.

Since the switch input to the control unit is prohibited, the main body does not suddenly operate when seated. Further, since the prohibition of the switch input is continued until the short-circuit state is eliminated, the operation corresponding to the switch in the short-circuit state is not performed.

す。Embodiment An embodiment of the present invention will be described below with reference to FIG. In FIG. 1, reference numeral 4 denotes an operation unit, which comprises switches 4-1, 4-2,. 5 is a seating detection unit,
The switch failure detection unit 7 receives the input from the operation unit 4 and the seating detection unit 5, determines the switch failure, and transmits a signal to the control unit 6. 7-1 is a switch signal, and 7-2
Is a seating detection signal. The control unit 6 outputs an output corresponding to a signal from the switch failure detection unit 7 to one main body.

以後、スイッチ故障検出部７は、操作部４のスイッチの
状態をそのまま制御部６へ伝えて、制御部６は本体１が
スイッチに応じた動作を行なう様出力を出す。By the way, 4-1 is a cleaning switch and 4-2 is a drying switch. First, a case where both are normal will be described.
When a person is seated, the seating detection unit 5 switches the switch failure detection unit 7
The switch failure detection unit 7 detects whether the switch of the operation unit 4 is in the ON state or the OFF state. Originally, the operation switch is not pressed simultaneously at the time of sitting, so if the switch is in the ON state, it is considered that condensation or a short circuit has occurred, and it is better not to judge that the signal is correct. The same applies to the case where the user touches the operation unit by mistake while sitting. When the switch is normal, since both the cleaning switch and the drying switch are in the OFF state, the switch failure detecting unit 7 determines that the switch is normal and sends a 7-
The switch 1 informs that the switches 4-1 and 4-2 are in the OFF state and that the switch 7 is seated. At this time, the main body 1 does not operate according to the switches 4-1 and 4-2.
Thereafter, the switch failure detection unit 7 transmits the state of the switch of the operation unit 4 to the control unit 6 as it is, and the control unit 6 outputs such that the main body 1 performs an operation according to the switch.
次に、洗浄スイッチ４−１がショート故障を起こして

７は正常と判断し、以後、制御部６へは、乾燥スイッチ
４−２の状態をそのまま伝えることになる。Next, a case where the cleaning switch 4-1 has a short-circuit failure will be described. As described above, at the time of seating, the switch failure detection unit 7 determines whether the switch of the operation unit 4 is in the ON state or OF.
Detects F status. At this time, the cleaning switch 4
Since -1 is in the ON state, the switch failure detection unit 7 determines that a short-circuit failure has occurred in the cleaning switch 4-1, and notifies the control unit 6 of the switches 4-1 and 4-2 from 7-1. Is ON
The transmission of the state of the switch between the state and the OFF state is prohibited, and the fact that the seat is seated is transmitted from 7-2. Therefore, the main body 1 is connected to the switch 4-
The operation corresponding to 1 is not performed. Thereafter, the switch failure detection unit 7
Determines that the cleaning switch 4-1 has failed until the cleaning switch 4-1 is turned off, and transmits a signal of the OFF state to the control unit 6.
Further, once it is turned off, the state of the cleaning switch 4-1 is transmitted to the control unit as it is. Also, drying switch 4-2
Since the switch is in the OFF state when seated, the switch failure detection unit 7 determines that it is normal, and thereafter transmits the state of the drying switch 4-2 to the control unit 6 as it is.
以上の動作を、着座検出部５が人の着座を検出するご
とに、繰り返す。The above operation is repeated each time the seating detection section 5 detects the seating of a person.
上記の様に、スイッチ故障検出部７により、人の着座

う不具合を取除くことができる。As described above, the switch failure detection unit 7 detects a short-circuit state of the switch of the operation unit 4 when a person is seated, and inhibits the corresponding switch input until the short-circuit state is resolved. The trouble that the main body operates from can be eliminated.

用便を妨げるようなことがなくなる。Advantages of the Invention As is clear from the description of the above embodiments, the sanitary washing device of the present invention is configured such that when the seating detection unit detects the seating, the operation unit switches from the operation unit to the control unit until all switches are turned off. By providing the switch failure detection unit that inhibits the switch input, even when the switch of the operation unit is in a short-circuit state due to dew condensation or a failure, the main body is operated immediately from the time of sitting and does not obstruct the convenience.
