It is equipped with 6. Reference numeral 47 is a valve pushing spring, and the valve body 41 is attached to the toilet seat 26a which is integrally provided with the knob cylinder 26.
At the same time, the valve operating shaft 39 in contact with the valve body 41 is pushed up. The square nut 42 screwed onto the valve operating shaft 39 has a square shape and is inserted into the square hole 26b of the knob cylinder 26 and locked for rotation. The pin 46 is press-fitted into the valve operating shaft 39 and engaged with a pin engagement groove 44a provided in the knob 44. Reference numeral 48 designates a switch operating ring which is ring-shaped and has a brim on the inside thereof, and is disposed around the outer periphery of the knob cylinder 26, and is provided integrally with the switch operating ring 48 and has a foot having a claw at its tip, which penetrates into the interior through the window of the knob cylinder 26. It engages with an engagement groove provided all around the outer circumference of the knob. The knob 44 is rotatably installed concentrically with the knob cylinder 26 and with a portion thereof protruding from the end surface of the operating knob 26', and is pressed by a knob pushing spring 49, but the foot of the switch operating ring 48 The base is in contact with the knob cylinder 26 and is in a locked state. In this state, pin 46

Here, the wires are connected so that the pump is turned off when the actuator is at the bottom of the step, and the pump is turned on when the actuator rides on the step. When pushed in the direction, the switch operation cam 50 is slid via the switch operation ring 48, but the pin engagement groove 4
Before the bottom of 4a contacts the pin 46, that is, Δ
It is set so that the actuator rides on the stepped portion, that is, the pump is turned off, within a range within this range. Therefore, regardless of the rotational position of the nozzle, if the knob 44 is pushed in the P direction against the knob pushing spring, the pump is first turned on by the switch 52 via the switch operating ring 48 and the switch operating cam 50, and the knob 44 The pin engagement groove 44a abuts on the pin 46. When the knob 44 is further pushed, the valve body 41 is moved by the valve pushing spring 47 via the pin 46 and the valve operating shaft 39.
The valve is opened by being pushed against it. At this time, the opening amount is limited by the position of the square nut 42, i.e., the square nut 41 and the bottom of the square hole 26b provided in the knob cylinder 26 as a stopper. Since it is screwed onto the shaft 39, the distance x can be adjusted by rotating the valve operating shaft 39, that is, the knob engaged by the pin 46 (with the knob cylinder fixed), and therefore the opening of the valve can be adjusted. The amount of cleaning water supplied to the nozzle 8 and the pressure can be adjusted.

Next, to describe the nozzle part in detail, the nozzle 8, which has one end fixed to the nozzle operating part 9 and the other end equipped with a spray body 53, is shaped like an arc and is housed in a recess 38 provided at the bottom of the toilet seat 5. It is rotated according to the operation of the nozzle operation part 9 without hitting the nozzle 1.
The injection body 53 has a branch fitting 54 in the shape of a T-shaped pipe, a ball 55 rotatably contained in the branch fitting 54, a bag-like shape with one or more injection ports on the side, and the outer shape of the ball 55. It has a smaller inner diameter and consists of an injection pipe (1) 56 for cleaning the anus and an injection pipe (2) 57 for cleaning female private parts, a branch fitting 54 and a nozzle 8, a branch fitting 54 and an injection pipe (1) 56. The injection pipe (2) 57 is fixed to each other in a watertight manner by press fitting. The mounting direction of the spray body 53 is vertical when the nozzle 8 is located horizontally, that is, in the stored state. Therefore, when the nozzle 8 is rotated and the rotation angle is within 90 degrees, the ball 55 rolls to the left in the figure due to gravity, blocking the injection pipe (2) for cleaning the female private parts, and the injection pipe (1) for cleaning the anus. is opened. On the other hand, when the nozzle rolling angle is 90 degrees or more, the ball 55 rolls on the right side in the figure due to gravity, blocks the injection pipe (1) 56 for cleaning the anus, and opens the injection pipe (2) for cleaning the female private parts. Also here nozzle 8
is rotated by θ ₁ turn, so that the cleaning water sprayed from the injection port of the injection pipe (1) is sprayed into the anal area.
At the position where the nozzle 8 has rotated by θ ₂ , the injection pipe (2) 57
Each injection port has angles α ₁ and α ₂ so that the cleaning water sprayed from the injection port is sprayed onto the female private parts.
is provided.

In addition, the switch 5 installed inside the toilet seat 5
2. Lead 5 from electrical parts such as toilet seat heater 11
8a and 58b are connected to electrical parts such as a pump, a heater, and a power cord 59 provided in the main body case 3 through the hinge pipe 7b via the protective tube 60, and are not exposed to the outside. Also, toilet seat 5
Since the lead wires are connected through the hinge part, which moves least when the lead wires are opened and closed, there is less damage to the lead wires, and since the lead wires are connected through the protective tube 60, there is no problem of damage due to abrasion.

Next, when using the multifunctional toilet of the present invention, first sit on the toilet seat, and when cleaning the anus after defecating, grip and rotate the operating knob 26' to rotate the nozzle 8. θ ₁
When rotated, the ratchet ball 32 and the engagement hole 33
b engages to indicate that the position is appropriate for anal cleansing. When the knob 44 is pressed with the palm of the hand while holding the operating knob 26', the switch 52 is first activated to turn on the pump. When the knob 44 is further pushed, the valve body 41 is pushed, the valve opens, and washing water is sprayed from the anus washing injection pipe (1) 56 to perform anus washing. When cleaning is finished, let go of the valve push spring 4.
7. The valve is closed by the knob spring 49 and the pump is turned off, and the nozzle is retracted by the action of the torsion coil spring 29. Next, when cleaning the female private parts, rotate the operation knob 26', rotate the nozzle 8 to θ ₂ , and press the knob 44 with your palm in the same way as when cleaning the anus. The female private parts are washed by spraying more water. When it's finished, let go of your hand and the valve will close automatically, just like with the anus.
The pump is turned off and the nozzle is retracted. here,
When the knob 44 is pressed in the stored state, cleaning water is sprayed from the spray pipe (1) 56 in the same way as when cleaning the anus, but the spray body 53 is cleaned by splashing from the storage recess wall 38a of the toilet seat 5. The spray body 53 can be kept clean.

As described above, by simply operating the nozzle operating section 9, it is possible to easily select between anal cleaning, female private parts cleaning, and propellant cleaning. Further, by turning the knob 44, the opening amount of the valve can be adjusted, and the water jet force can be easily adjusted.

Now, when the toilet seat 5 is open, such as when a man urinates, there is very little risk of the man urinating because the nozzle operation part 9 etc. are attached to the toilet seat 5, and the water channel and lead wire are inside the hinge. Because of the way it is, it is very clean. Furthermore, even if the knob 44 is pressed with the toilet seat 5 open, the pump is turned on and the valve is opened, but since the communication port 22 of the hinge pipe 7a is blocked, cleaning water may be sprayed from the injection port. It won't get the place wet.

[Function and effect]

According to the present invention, when the nozzle is used, that is, when the toilet seat is reclined, the waterway communicating with the nozzle is opened, and the toilet seat can be opened upward for cleaning the toilet bowl, urinating for men, etc. without any problem in cleaning by spraying. In some cases, the waterway communicating with the nozzle is blocked, so even if an erroneous operation occurs, there will be no spray from the nozzle, and your clothes will not get wet. Moreover, since the structure is extremely simple, it can be provided at low cost.
