With the above-described structure, the cleaning nozzle of the present invention allows the cleaning water to be discharged only from the main nozzle hole if the on-off valve is kept closed, and intensive cleaning is possible. Then, the cleaning water is discharged from both the main nozzle hole and the sub nozzle hole group. Here, since the jet discharged from at least one of the sub nozzle holes is configured so as to contact and interfere with the jet from the main nozzle hole, the jet from the main nozzle hole is a physical fluid of the jet from the sub nozzle hole. The contact position in the portion to be cleaned changes in comparison with the case of the main nozzle hole alone, and the jet flow from other sub nozzle holes is also added to make the jet flow more dispersed than the jet flow of the main nozzle hole alone. Become. Further, the opening area of the nozzle is enlarged by opening the auxiliary nozzle hole for the cleaning water sent into the cleaning nozzle at a predetermined flow rate. That is, since the water is divided into the main nozzle holes and the sub nozzle holes and discharged, the jet speed of the wash water is also reduced, and the jet flow is dispersed and has a gentle sensation.

In the cleaning apparatus of the present invention, the centralized cleaning and the distributed cleaning can be arbitrarily selected regardless of the amount of water set by the cleaning water supply means by selecting the first switch for selecting the opening / closing valve. Further, the opening / closing valve is intermittently controlled to be opened / closed by the selection of the second switch, and intensive cleaning and distributed cleaning are alternately repeated, so that the user does not feel monotonous. Further, the jet flow from the main nozzle hole is caused to come into contact with and interfere with the jet flow from the sub nozzle hole, and by repeating this intermittently, the jet flow oscillates, so that the cleaning effect is improved and the massage effect on the portion to be cleaned is also obtained.

Next, when the first switch 29 is turned on, the opening / closing valve 27 is opened via the opening / closing control circuit 30, and the cleaning water is diverted to the sub passage 17 through the bypass passage 26 and the main nozzle hole 18. It is discharged from both of the sub nozzle hole groups 19. Here, the jet flow from the main nozzle hole 18 receives the physical fluid force of the jet flow from the sub nozzle hole group 19a, and the position to be cleaned moves to the right side of the drawing as shown in FIG. 19b
The jet flow from the above forms a dispersed jet Pw shown in FIG. Further, the sub-nozzle hole group 19 opens with respect to the cleaning water fed into the nozzle cylinder 15 at a constant flow rate by the setting means 35, and the sub-nozzle hole group 19 and the sub-nozzle hole group 19 are branched and discharged. Therefore, the jetting speed is also reduced, and the jet becomes a dispersed and gentle sensation. Here, the jet flow from the sub nozzle hole group 19a acts to move the jet flow from the main nozzle hole 18 to the right side in the drawing, and the jet flow from the sub nozzle hole group 19b acts to supplement the moved jet flow. Due to these synergistic effects, the part to be cleaned can be cleaned over a wide range.

Next, when the first switch 29 or the second switch 32 is turned on, the on-off valve is controlled to perform dispersion cleaning or intermittent cleaning in which concentration and dispersion are alternately repeated. The first switch 29 or the second switch 32 is turned on and the opening / closing valve 27 is opened while the water amount of the setting means 35 set in the intensive cleaning is set to a low water amount, for example, the water amount adjusting range 1 in FIG. In this case, it is conceivable that sufficient cleaning water is not ejected from the sub-nozzle hole group 19 and the desired cleaning effect is not exhibited.
That is, the degree of dispersion of the jet flow in the dispersed cleaning or the swing range of the jet in the intermittent cleaning depends on the jet flow rate from the sub-nozzle hole group 19, and if the wash water flow rate is small, a sufficient dispersion or swing effect cannot be obtained.

In this embodiment, when the first switch 29 or the second switch 32 is turned on, the set value detection circuit 38 detects the set value of the setting means 35 and the arithmetic circuit 3
The required increased water amount is calculated in 9, and the water supply control unit 36 is controlled so as to send a water amount that is a predetermined amount larger than the water amount set by the setting unit 35. This relationship is shown in B of FIG. For example, when the setting value of the setting means 35 in the concentrated cleaning is 1, when the first switch 29 or the second switch 32 is turned on, the bias circuit 37 controls the water supply control means 36 so as to increase the water amount by ΔQ 1 . As a result, when the concentrated cleaning is switched to the distributed cleaning, the bias circuit 37 is automatically operated.
Since the washing water amount is increased by the water amount setting means 35
The feeling of use and the feeling of washing do not deteriorate even when the amount of water is set to low.
