Description

  The present invention relates to a sanitary washing device that ejects washing water toward a human body part.

Conventionally, in this type of sanitary washing apparatus, the waiting time until the washing water is jetted toward the local body at the start of washing is not changed by the signal from the driving distance measuring means for measuring the driving distance and the driving time of the washing nozzle. As described above, the torque applied to the motor is controlled so as to prevent the waiting time from changing by changing the torque of the motor (see, for example, Patent Document 1).
JP 11-161339 A

  However, in the conventional configuration, in the case where the control unit can correctly determine the signal measured by the driving distance measuring unit that measures the cleaning nozzle driving distance and the driving time, the cleaning water is directed toward the human body part at the time of cleaning. The waiting time until erupting was able to be kept unchanged. However, when the signal measured by the drive distance measurement unit differs from part to part and the signal input to the control unit changes, it becomes impossible to correctly determine the distance and time driven by the nozzle unit, and at the start of cleaning. The driving distance and driving time until the cleaning water is jetted toward the human body part become abnormal, and the nozzle means cannot be properly projected to the cleaning position, giving the user a sense of incongruity.

  The present invention solves the above-mentioned conventional problems, and even when the signal measured by the driving distance measuring means is different for each part, at the start of cleaning, the waiting time until the cleaning water is jetted toward the human body part and the cleaning An object of the present invention is to provide a sanitary washing device that can always maintain a constant position and can perform stable local washing.

  In order to solve the above-mentioned conventional problem, the driving means includes a driving distance measurement signal changing means for changing the driving distance signal detected by the driving distance measuring means of the nozzle means to a stable signal and outputting the same, and the control means changes the driving distance measurement signal. The torque applied to the motor for driving the nozzle means is controlled based on the drive distance signal of the means.

  As a result, even if the signal measured by the drive distance measurement means differs for each part, the waiting time and the washing position until the washing water is jetted toward the human body part can be kept constant at the start of washing. Can be washed locally.

  The sanitary washing device of the present invention can always make the waiting time and the washing position until the washing water is jetted toward the local body part at the start of washing, and can perform stable local washing.

Is determined to be fast, and the output voltage is controlled to be low in order to weaken the torque of the motor 3. If the control means 6 does not have a stable signal from the drive distance measurement signal changing means 5 even though the motor 3 is driven, it is determined that there is an abnormality in the drive operation of the nozzle means 1. Then, a signal is output to the nozzle means abnormality information output means 8.

  As described above, in the present embodiment, when the gear 2 is rotated, the driving distance measuring unit 4 detects the mark applied to the gear 2, and the stabilized signal from the driving distance measuring signal changing unit 5 is detected from the signal. If the control means 6 does not exist, the control means 6 determines that there is an abnormality in the driving operation of the nozzle means 1 and outputs a signal to the nozzle means abnormality information output means 8 to drive the nozzle means 1 accurately to the user. It is possible to notify that it is not possible.
