It is configured as a rotary valve driven by

  Next, the operation of the sanitary washing toilet seat device 10 (nozzle unit 20 of the local washing device) according to the embodiment configured as described above will be described. FIG. 8 is an explanatory diagram showing how the nozzle unit 20 operates. The control device of the sanitary washing toilet seat device 10 determines that the user is seated on the toilet seat 14 by the seating sensor 13 and that the washing switch for butt on the operation panel 18 has been pressed to instruct the start of the tail washing. If it determines, the rotation gear 45 which meshes with the drive gear 25 will be rotated by the motor 24, and the cylinder 40 will be rotated. When the cylinder 40 rotates, the plurality of ribs 35 provided on the nozzle 30 relatively move along the spiral groove 44a formed on the inner peripheral surface of the cylinder 40, and the nozzle 30 moves toward the washing position for the butt washing. To advance. When the nozzle 30 reaches the cleaning position, the control device controls the switching valve (motor) so that the cleaning water from the pulsation pump is supplied to the nozzle hole 32 a of the nozzle 30 via the hose 21. As a result, washing water is ejected from the nozzle hole 32a toward the anus of the human body, and butt washing is started. When the control device determines that the stop switch of the operation panel 18 is pressed and the stop of the buttocks cleaning is instructed, the control device stops the water supply to the nozzle 30. Then, the rotating gear 45 is reversely rotated by the motor 24 so that the nozzle 30 is retracted toward the accommodation position and is accommodated in the cylinder 40. The control device controls the switching valve (motor) so that the cleaning water is ejected from the nozzle cleaning device 60 toward the nozzle 30 when the nozzle 30 is moving from the cleaning position to the storage position or when the nozzle 30 reaches the storage position. The nozzle 30 is washed.

  Further, when the control device determines that the user is seated on the toilet seat 14 by the seating sensor 13 and determines that the bidet cleaning switch of the operation panel 18 is pressed and the start of bidet cleaning is instructed, the motor 24, the cylinder 40 is rotated, and the nozzle 30 is advanced toward the cleaning position for bidet cleaning. When the nozzle 30 reaches the cleaning position, the control device controls the switching valve (motor) so that the cleaning water from the pulsation pump is supplied to the nozzle hole 32 b of the nozzle 30 via the hose 22. Thereby, washing water is ejected from the nozzle hole 32b toward the bidet part of the human body, and bidet washing is started. When the control device determines that the stop switch of the operation panel 18 is pressed and the stop of the bidet cleaning is instructed, the control device stops the water supply to the nozzle 30. Then, the rotating gear 45 is reversely rotated by the motor 24 so that the nozzle 30 is retracted toward the accommodation position and is accommodated in the cylinder 40. The control device controls the switching valve (motor) so that the cleaning water is ejected from the nozzle cleaning device 60 toward the nozzle 30 when the nozzle 30 is moving from the cleaning position to the storage position or when the nozzle 30 reaches the storage position. The nozzle 30 is washed.

When water enters the cylinder 40, the water infiltrated by the rib 35 sliding in the spiral groove 44a as the cylinder 40 rotates is sent out to the rear of the cylinder 40 and leaks from the opening at the rear end of the cylinder 40. There is a risk of causing a failure of the local cleaning device. Further, when water enters the cylinder 40, the sliding resistance of the rib 35 sliding in the spiral groove 44a increases, and the load on the motor 24 may increase. In the present embodiment, since the plurality of drain grooves 44b extending in the axial direction so as to cross the spiral groove 44a are formed on the inner peripheral surface of the cylinder 40, even if water enters the cylinder 40, 40 can be discharged along the drainage groove 44b. Therefore, in the nozzle unit 20 of this embodiment, the malfunction mentioned above accompanying the penetration | invasion of the water in the cylinder 40 does not arise.

The water flowing forward through the groove 44b can be discharged to the outside (in the toilet bowl of the toilet 1) through any of the through holes 48.

  Further, in the local cleaning device of the embodiment, since the drain hole 55 projecting in a cylindrical shape downward from the outer peripheral surface is provided at the distal end portion of the case 50, the water collected at the distal end portion of the case 50 is satisfactorily externally ( It can be discharged into the toilet bowl of the toilet bowl 1, and the water discharged from the case 50 can be prevented from being transmitted to the outer peripheral surface of the case 50 to keep the case 50 clean.

  In the embodiment, the through hole 48 penetrating in the radial direction is formed at the tip of the cylinder 40, but the through hole 48 may be omitted. In this case, if the drainage groove 44b extends to the opening edge at the tip of the cylinder 40, the water that has entered the cylinder 40 can be discharged to the outside of the cylinder 40 along the drainage groove 44b.

  In the embodiment, the annular outer circumferential rib 43 is formed on the outer circumferential surface of the cylinder 40, and the annular inner circumferential groove 53 fitted to the outer circumferential rib 43 is formed on the inner circumferential surface of the case 50. An outer peripheral groove may be formed on the outer peripheral surface, and an inner peripheral rib fitted to the outer peripheral groove may be formed on the inner peripheral surface of the case 50. The rib is not necessarily limited to an annular shape, and may be formed in an arc shape and may have any shape as long as it can be fitted into the groove.

  In the embodiment, as the fitting portion to be fitted with the spiral groove 44a of the cylinder 40, the outer peripheral surface of the rear end portion of the nozzle 30 is inclined with respect to the axial direction of the nozzle body 31 so as to follow the shape of the spiral groove. Although the extending ribs 35 are provided, the present invention is not limited to this, and for example, a plurality of circular protrusions 35B may be provided as shown in a modified nozzle 30B shown in FIG. Further, a rollable ball may be disposed on the outer peripheral surface of the rear end portion of the nozzle body 31.

  In the embodiment, the external gear 45 is provided on the outer peripheral surface of the rear end portion of the cylinder 40 so as to rotate coaxially with the cylinder 40. However, the present invention is not limited to this, and the rear end surface of the cylinder 40 is not limited thereto. Further, an annular bevel gear such as a face gear may be provided so as to rotate coaxially with the cylinder 40, and the motor may be arranged so that a drive gear attached to the rotation shaft meshes with the bevel gear.
