It has an elastic member 31 for moving the movable water supply body 26 to the retracted position when is stopped. In addition, the opening end 32 of the air supply pipe 29 is positioned so that the movable water supply body 26 is located in the water supply passage 24 with the nozzle element 25 advanced to the human body local position.
It is fixed by extending coaxially. A movable plate 33 is provided on the outer peripheral portion of the air supply pipe 29.
A stopper 34 is provided which cooperates with the forward / backward movement of 6 and is provided so as to be able to close the water supply passage 24, and stops the movable plate 33 at a position where a flow passage for washing water is secured at the advanced position of the movable water supply body 26. . Reference numeral 35 is a check valve that prevents the backflow of wash water from the air supply pipe 29 to the air pump 27 when the supply of air is stopped.

2 and 3 show an enlarged sectional view and a top view of the cleaning nozzle 25. It has a nozzle chamber 36 communicating with the water supply passage 24, a main ejection hole 37 communicating with the nozzle chamber 36, and an auxiliary nozzle hole group 38. The auxiliary nozzle hole group 38 is provided so as to be inclined at a predetermined angle θn with respect to the main ejection hole 37, and is arranged at a predetermined pitch Pn on both sides of the main ejection hole 37, and is ejected from the main ejection hole 37. The auxiliary jet from the auxiliary nozzle hole group 38 is configured to contact and interfere with the main jet.

Reference numeral 39 denotes a water pump 16 and an air pump 27.
Is a first water supply control means for controlling the
0, a water pressure adjusting switch 41, and a water pressure adjusting circuit 42. When the first switch 40 is turned on, the water pump 16
Also, the air pump 27 is driven to supply the double-layered washing water in which bubbles are mixed at a predetermined ratio to the washing nozzle 25, and a desired water force, that is, the flow rate of the washing water can be adjusted by the water force adjusting switch 41.

Reference numeral 43 is a second water supply control means for controlling the operation of the air pump 27, and the operation control circuit 4 for controlling the driving and stopping of the second switch 44 and the air pump 27.
When the second switch 44 is turned on, the air pump 27 is stopped and only the cleaning water is supplied to the cleaning nozzle 25.

In the above-mentioned structure, the operation of this embodiment will be described below.
The operation will be described. When the first switch 40 is turned on, the motors 17 and 28 start rotating by the first water supply control means 39, and the cleaning water is supplied to the nozzle cylinder 23 by the water pump 16 through the warm water tank 18.
The water pressure of the wash water acts on the end surface of the movable water supply body 26 and begins to move forward against the force of the elastic member 31. At this time, the movable plate 33 provided on the outer peripheral portion of the air supply pipe 29 is connected to the water supply passage 2
4, the area corresponding to the cross-sectional area of the water supply passage 24 is increased as a pressure receiving area, and the advancing output of the movable water supply body 26 is increased. When the movable water supply body 26 advances due to the water pressure and reaches the human body local position, the movable water supply body 26 comes into contact with the stopper 34 to move the movable plate 3
3 is stopped, the water supply passage 24 is opened as shown in FIG. 1, and the wash water passes through the water supply passage 24. On the other hand, at the same time that the water pump 16 operates, the air pump 27 also operates and the check valve 35,
The compressed air is mixed into the cleaning water through the air supply pipe 29 from the opening end 32 at a predetermined ratio, and the cleaning water containing the bubbles flows into the cleaning nozzle 25. At this time, since air is mixed in the process of passing through the water supply passage 24, that is, at a stage close to the nozzle element 25, there is no sudden expansion or contraction of the flow path of the wash water after mixing with air, and before separation into a gas phase and a liquid phase Then, the water is discharged from the jet holes through the water supply passage 24, and the nonuniformity of the air bubbles is prevented, and the air bubbles having a stable particle diameter are supplied. Further, the flow velocity of the cleaning water passing around the air supply pipe 29 in the water supply passage 24 is increased, and the air is mixed in a state where the pressure at the opening end 32 of the air supply pipe 29 is low due to the ejector effect by the passage of the cleaning water. it can. This makes it possible to forcefully mix air with a small capacity air pump, that is, at a low discharge pressure.

The cleaning water flowing into the cleaning nozzle 25 is simultaneously ejected from the main ejection hole 37 and the auxiliary nozzle hole 38. At this time, the cleaning water ejected from each ejection hole contains air bubbles and becomes an irregular intermittent flow. That is, the jetting force of the wash water jetted from each jet hole changes in intensity, and the jetting water shows the amplitude Wn in FIG. It will swing like

This point will be described in detail with reference to the rocking principle diagrams shown in FIGS. 4 (a) and 4 (b). In the figure, (a) shows a state in which bubbles are not mixed, and (b) shows a state in which bubbles are mixed. Here, the jet output of the washing water from the main jet hole 37 is Vm, and the jet output from the auxiliary nozzle hole group 38 is Vm.
Letting a and Vb, the jet output from the auxiliary nozzle hole group 38 is decomposed into horizontal components Va1 and Vb1 and vertical components Va2 and Vb2 with respect to the jet flow of the main jet holes 37, and if bubbles are not mixed, it is a vertical component Va2. And the forces of Vb2 are balanced and stable, and a concentrated jet flow as shown in FIG. 2 is formed. On the other hand, when air bubbles are mixed, the cleaning water ejected from the main ejection holes 37 and the auxiliary nozzle hole group 38 becomes an irregular intermittent flow, so that the balance between Va2 and Vb2 is disturbed as shown in FIG. 4B. The jet will oscillate as shown in FIG.
The inclination angle θn and the pitch Pn of the auxiliary nozzle hole group 38
The swing amplitude Wn can be easily adjusted by changing the set value of.

As described above, when air bubbles are mixed, a cleaning jet oscillating in a wide range can be obtained, and the above-described structure prevents air bubbles from becoming non-uniform and can supply air bubbles having a stable particle size. When ejected from the cleaning nozzle 25, there is an appropriate stimulus, a soft cleaning sensation is obtained, and since the bubble particle size does not increase, the popping noise of bubbles when ejected from the cleaning nozzle 25 can be reduced and the scattering of cleaning water can be reduced. it can.

Next, when the second switch 44 is turned on, the air pump 27 is stopped and only the cleaning water in which no air bubbles are mixed is supplied to the cleaning nozzle 25 to form a concentrated continuous flow as shown in FIG. It is ejected toward the human body. If the second switch 44 is opened, it is possible to return to the bubble-mixed swing cleaning again.

As described above, according to the present embodiment, the cleaning nozzle 25 is provided with the main ejection holes 37 and the auxiliary nozzle hole group 38, and the cleaning water supply means 15 and the air mixing means 30 are provided to mix the air. If this is done, rocking cleaning containing air bubbles, that is, a wide range cleaning pattern, can be obtained.
If the mixing of bubbles is stopped, a concentrated continuous flow can be arbitrarily selected. This makes it possible to remotely control the variable cleaning pattern and simplify the configuration. Also, since the second switch 43 is not effective unless the first switch 40 is prioritized, that is, after the first switch 40 is turned on, the bubble swing cleaning is always started, so that the user feels the pain of intensive cleaning at the initial stage of cleaning. Never give. This is particularly suitable for people with hemorrhoids.

Further, since air is mixed in the process of passing through the water supply passage 24 provided in the movable water supply body 26, there is no sudden expansion or contraction of the flow path of the washing water after mixing with air, and there is no gas phase or liquid phase. Since the bubbles are ejected from the cleaning nozzle 25 through the water supply passage 24 before the separation, the bubbles are prevented from becoming nonuniform, and bubbles having a stable particle size are generated. The popping noise can be reduced and the scattering of cleaning water can be reduced. Further, since the opening end 32 of the air supply pipe 29 is provided in the water supply passage 24, air is mixed in with the flow velocity of the wash water passing therethrough being increased, and the ejector effect by the passage of the wash water is achieved. This can reduce the pressure at the open end. This allows the air pump 2
7, it is possible to reduce the capacity, that is, forcedly mix air with a low discharge pressure.

The operation and operation of the first switch 40 and the second switch 44 are the same as those of the sanitary washing device of FIG. 1, and detailed description thereof will be omitted. The first switch 40 is turned on to drive the water pump 16 and the air pump 27,
When the cleaning water containing air bubbles is supplied to the cleaning nozzle 25, an oscillating cleaning jet is obtained. Further, the second switch 44 can arbitrarily select a concentrated cleaning pattern using only the rocking cleaning jet and cleaning water. Here, when at least the first switch 40 is turned on and then the third switch 47 is turned on, the fluctuation control circuit 48 controls the air pump 27, and the amount of air mixed in the wash water is as shown in FIG. It is increased / decreased in a predetermined cycle fa. As a result, the bubble-mixed rocking cleaning and the intensive cleaning pattern by continuous steady flow are automatically repeated, and there is no monotonous feeling at the time of cleaning due to the change in strength of the cleaning jet and the concentrated dispersion of the cleaning area, and The cleaning power is improved. Here, the fluctuation range of the air amount that gives fluctuation is automatically set by the air adjustment amount setting circuit 49 according to the water force of the wash water, that is, the water amount set by the user with the water force setting switch 41. FIG. 7 is a characteristic diagram showing the relationship between the water force and the air amount, and the air adjustment amount setting circuit 4
In 9, the upper limit and the lower limit of the fluctuation amount of air are set according to the water force selected by the water force setting switch 41. In FIG. 7, for example, when the water force 3 is selected, the air amount is increased / decreased in the range from the upper limit Qmax to the lower limit Qmin. As a result, a suitable cleaning feeling can be obtained according to each water force. In order to achieve good swinging of the wash water, it is necessary to adjust the amount of mixed air according to the amount of water, and in particular, the wash nozzle 2 of this embodiment.
In the configuration of No. 5, it is necessary to set the air mixing ratio (mixed air amount / washing water amount) to be large when the water amount is small, and as shown in FIG. 7, the air amount tends to increase as the water pressure decreases. Is going.

As described above, according to the present embodiment, the first switch 40 and the second switch 44 make it possible to easily select the wide bubble-containing cleaning and the concentrated cleaning by the continuous steady flow. Since the third water supply control means for changing the amount of mixed air in a predetermined cycle by turning on the third switch 47 is provided, it is possible to concentrate the cleaning by wide bubble mixing and continuous steady flow. A cleaning mode that automatically repeats cleaning can be selected. As a result, the degree of freedom in selecting the cleaning pattern is expanded, and the monotonous feeling at the time of cleaning is eliminated due to the change in the strength and weakness of the cleaning jet and the concentrated dispersion of the cleaning area. Can be made.

Further, since the air adjustment amount setting circuit 49 for setting the upper limit and the lower limit of the mixed air according to the water pressure set by the water pressure adjusting switch 41 is provided, the fluctuation according to the favorite water force set by the user.
