FIG. 4 is a diagram showing a flow path configuration, in which cleaning water is supplied from a branch faucet 13 provided in a water pipe 12, through a strainer 14, a check valve 15, a constant flow valve 16, a solenoid valve 17, and a heater unit 18. The flow rate control switching valve 19 reaches the flow rate control switching valve 19, and the flow channel is switched to the cleaning nozzle 11 and the toilet bowl cleaning nozzle 20 by the flow rate control switching valve 19 and is ejected.

Further, the air pump 21 is operated and the air switching valve 22 is used to switch to the cleaning nozzle 11, so that bubbles can be mixed into the cleaning water and ejected.

FIG. 5 shows a remote controller 23 operated by the user.
An example is shown.

The operation and action of the sanitary washing device constructed as above will be described below.

When the user sits on the toilet seat to wash the front part of the human body, the bidet A switch 24 or bidet B switch 25 of the remote controller 23 is operated to perform a washing control circuit (not shown).
, The stepping motor 9 is driven by a certain amount, and the arm 10 is rotationally moved to a predetermined angle α ° shown in FIG. After the completion of the movement, the main body water supply unit is activated and the cleaning water is sent into the arm 10 and ejected from the nozzle 11. When the cleaning stop switch is pressed, the supply of cleaning water is stopped, the stepping motor 9 is reversed, and the arm 10 and the nozzle 11 are stored in the toilet seat 2.

In the present invention, two cleaning modes for the female urethra and vagina are prepared as the local cleaning position,
It can be selected by a bidet A switch 24 and a bidet B switch 25, respectively.

As shown in FIG. 6, at the time of cleaning, the spray angle of the cleaning water and the trajectory of the cleaning water are determined by the set arm feeding angle α, the nozzle mounting angle β to the arm, and the arm length L. In the present invention, the values of α, β, and L that determine the washing positions of the urethra and vagina are narrowed to the optimum values by experiments, and the following specifications are obtained.

L = 60 mm β = 130 degrees (common to Bide A switch and Bide B switch) Bide A switch: α = 71 degrees, Bide B switch: α = 6
7 degrees At this time, as shown in FIG. 7, the jet angle of the washing water is as small as θ (about 30 degrees), and flows from the front of the human body sitting on the toilet seat to the front part of the human body and strokes from the front to the rear. .

FIG. 8 shows the shape of the jet flow when the cleaning water is collided with the flat plate. FIG. 8A shows the shape of the jet flowing through the flat plate when the cleaning water sprayed from the cleaning nozzle 11 of this embodiment is collided with the flat plate horizontally placed at the position of the broken line AB shown in FIG. I saw it. A region 26 is a region where the cleaning water sprayed from the cleaning nozzle directly collides with the flat plate, and a region 27 is a region where the cleaning water colliding with the region 26 spreads backward and flows. FIG. 8B is a jet flow flowing through the flat plate when the flush water sprayed from the flush nozzle installed in the rear of the toilet of the conventional embodiment collides with the flat plate horizontally placed at the position of the broken line AB shown in FIG. The shape of is viewed from directly above. The region 28 is a region that directly collides with the flat plate, and the region 29 shows a region where the cleaning water that collides with the region 28 spreads forward and flows. Figure 8
As can be seen from (b), since the cleaning water ejected from the conventional cleaning nozzle has a large ejection angle γ, the cleaning water concentrates in the area 28 and collides, and since the collision energy is large, it does not flow straight in two directions. It flows separately.

On the other hand, since the jetting angle of the washing water jetted from the washing nozzle of this embodiment is smaller than the jetting angle of the washing water jetted from the conventional washing nozzle, the area directly impinging on the flat plate is large and dispersed. Then, since the collision energy is small, the collision energy flows straight backward, and a wider area can be washed from the front of the human body part to the rear.

As described above, the cleaning water ejected from the cleaning nozzle contacts the human body part and flows so as to be stroked from the front part to the rear part of the body, so that the whole part can be cleaned easily at once in a wide area, and the user can It is possible to eliminate the discomfort given to sensitive people who do not like to be directly exposed to the wash water, prenatal and postpartum persons, and persons suffering from diseases such as vaginitis, and to improve usability. And, for example, when washing the local area during small use, it is not necessary to move the body by changing the seating position, stretching the back muscles or leaning forward, and in a comfortable posture, from the front of the urethra to the vagina. Can be washed backwards. Furthermore, since the washing is performed from the front to the rear of the human body part, there is no concern that the washing water that has passed through the anus will hit the vagina, and hygienic washing can be performed.

The bidet cleaning A and B switches 24 and 25
The strength of the washing water can be adjusted while the is operated and the bidet washing is performed. When the water pressure switch 30 of the remote controller 23 is operated, the flow rate control switching valve 19 acts so that the strength of the flow rate of jetting wash water can be changed stepwise to obtain the water force desired by the user. By providing a mechanism for adjusting the flow rate of the jet flow of the cleaning nozzle in this way, even if there are individual differences such as those who prefer strong jets and weak jets, each user thinks that it is optimal for cleaning The anterior part of the human body can be washed with a flow rate or a desired flow rate.

On the other hand, the soft switch 31 of the remote controller 23
When the bidet A and B switches 24 and 25 are operated after pressing, the flow rate ejected from the cleaning nozzle automatically changes during cleaning. That is, the flow rate control switching valve 19
At this time, the flow rate of the wash water is automatically controlled according to the time chart of FIG. In FIG. 9, the flow rate is gradually increased from Fa to Fb during a time ta after the start of cleaning, and thereafter, the flow rate is repeatedly increased and decreased between Fb and Fc. In this way, at the start of washing, by starting the washing with a mild jet with less irritation, it is possible to reduce the pain or anxiety at the beginning of washing, and then gradually increase the flow rate of the washing water. The cleaning power can be improved and the entire local area can be cleaned easily in a wide area at one time. Further, since the flow rate of the washing water is repeatedly increased and decreased after the lapse of a predetermined time, the monotonous feeling at the time of washing can be eliminated and a massage effect can be obtained.

Further, even if there is a difference in seating position of the user, a physique, or other individual differences, the nozzle position switch 32 of the remote controller 23 allows the cleaning position which each user thinks is optimum at the time of cleaning, or a preferred cleaning position. The stepping motor 9 of the driving means drives the cleaning nozzle so that the position of the cleaning water can be adjusted.
