可能な洗浄形態が選択できるものである。According to the sanitary washing nozzle of the present invention, the first and second nozzle chambers are provided in the nozzle element to divert the washing water by the flow dividing wall, and the first and second nozzle chambers communicate with the respective nozzle chambers. The jets ejected from the second ejection hole are configured to interfere with each other, and an air mixing unit for forcibly mixing air into the wash water is provided, so if air is not mixed, it will be ejected separately from the first and second ejection holes. The washed water comes into contact with each other and merges into a concentrated continuous flow, which is ejected toward the human body part. Also, if air is forcibly mixed in, the cleaning water containing bubbles will spout simultaneously from the first and second spout holes, but the cleaning water spouting from each spout hole contains bubbles and is irregular. It becomes an intermittent flow. That is, the jetting force of the washing water jetted from each jet hole changes in strength and weakness, and the two washing jets come into contact with each other and interfere with each other.

The air supply pipe is fixedly mounted so that the opening end is located in the water supply passage, and air is mixed in the process of passing through the water supply passage provided in the movable water supply body, that is, at the stage close to the nozzle element. There is no rapid expansion or contraction of the flow path of the wash water after mixing, and the water is discharged from the jet hole through the water supply channel before it is separated into the gas phase and the liquid phase. As a result, non-uniformity of air bubbles is prevented and bubbles with a stable particle size are generated.There is moderate irritation when ejected to the human body part, a soft cleaning feeling is obtained, and the bubble particle size does not increase. In addition, the popping noise of air bubbles at the time of ejection from the cleaning nozzle can be reduced, and the scattering of cleaning water can be reduced. Further, since the opening end of the air supply pipe is located in the water supply passage, air is mixed in with the flow velocity of the washing water passing therethrough increased, and the above-mentioned opening is caused by the ejector effect due to passage of the washing water. The end pressure can be reduced. This makes it possible to forcefully mix air with a small capacity air pump, that is, at a low discharge pressure.

る。Here, the operation of the movable plate 33 will be described. When the movable water supply body 26 is in the retracted state as shown in FIG. 3, the movable plate 33 contacts the end surface of the movable water supply body 26 and moves the water supply passage 24 to the retracted position in the closed state. When the wash water is supplied from the water supply port 22, the water pressure is movable.
The movable water supply body 26 is moved forward by acting on the end surface of 6 and the movable plate 33. The force for moving the water supply body 26 is proportional to the water pressure and the pressure receiving area on which the water pressure acts. When the movable plate 33 does not exist, the wash water flows into the water supply passage 24 at the same time as it flows in, so that the cross-sectional area of the water supply passage 24 does not act effectively as a pressure receiving area and the advancing output of the movable water supply body 26 decreases. In the present embodiment, as shown in FIG.
Since 4 is closed, the pressure receiving area shown by the hatched portion S can be increased, and the advance output can be improved.

わち低い吐出圧で空気の強制混入が可能となる。When the movable water supply body 26 advances due to water pressure and reaches the human body local position, it abuts on the stopper 34 and the movable plate 33 stops, and as shown in FIG. 1, the water supply passage 24 is opened and washing water is supplied to the water supply passage. Pass 24. On the other hand, the water pump 16
The air pump 27 also operates at the same time that the check valve 3
5. The compressed air is mixed into the cleaning water from the opening end 32 at a predetermined ratio through the air supply pipe 29, and the cleaning water containing the bubbles flows into the nozzle element 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. Water supply channel 2
The flow rate of the wash water passing around the air supply pipe 29 in 4 is increased, and air can be mixed in under a state where the pressure at the open end 32 of the air supply pipe 29 is low due to the ejector effect due to the passage of the wash water. This makes it possible to forcefully mix air with a small capacity air pump, that is, at a low discharge pressure.

ことができる。The wash water that has flowed into the nozzle element 25 is divided into the first and second nozzle chambers 36 and 37 by the flow dividing wall 40, and the first and second ejection holes 38 and 39 that communicate with each other.
At the same time, cleaning water containing bubbles is jetted out. 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. As a result, the cleaning jet is obtained in which the bubbles are mixed and the rocking is swung in a wide range. Further, as described above, since the non-uniformity of the bubbles is prevented and the bubbles having a stable particle size can be supplied, there is moderate irritation when ejected to the human body part, a soft cleaning feeling is obtained, and the bubble particle size does not increase. In addition, the popping noise of the bubbles at the time of jetting from the nozzle element 25 can be reduced, and the scattering of cleaning water can be reduced.

向けて噴出される。Next, when the jet flow selection switch 42 selects the cleaning by the continuous flow in which air bubbles are not mixed, the second water supply control means 44 stops the driving of the air pump 27 and the air amount decreases. The number of rotations of the water pump 16 is increased so as to compensate for the lowered feeling of washing, and the flow rate of washing water is increased. That is, the flow rate ejected from the nozzle element 25 in the air bubble cleaning is the sum of the amount of water and the amount of air,
Since the flow rate is set so that a predetermined cleaning feeling can be obtained when it comes into contact with the human body part, the actual flow rate decreases when the air supply is stopped, and the cleaning feeling deteriorates. Therefore, when the cleaning in which bubbles are not mixed is selected, it is necessary to increase the flow rate of the cleaning water. The increased cleaning water is supplied to the nozzle cylinder 22 and the water supply passage 2.
4 into the nozzle element 25, and each of the ejection holes 38,
Eject from 39 at the same time. The washing water jetted separately comes into contact with each other and merges, and since it is a continuous flow in which no bubbles are mixed, it becomes a concentrated jet as shown in FIG. 2 and is jetted toward the human body part.
