The valve operation body 30 is provided with a water discharge pipe opening 32 for the flush water ejection device 3 on the peripheral wall on the other end side of the valve operation body 30. A compression-type annular hermetic elastic body 73 (for example, an O-ring, an X-ring, and a V-packing) is mounted on one end portion of the moving rod 71, and the other end portion of the valve operating body 30 is inserted (E-ring 77 It is preferable to prevent the pivot rod 71 from being removed with a tool etc.), and a pivot rod 71 that rotates within a specified angle range without contacting or moving away from the valve operating body 30 is provided. A spool valve 70 comprising a rotary rod 71 and a cylindrical rod 74 with a knot is provided, and a protrusion 72 provided at the other end of the rotary rod 71 by rotation of one end of the rotary rod 71. The knurled cylindrical rod 74 that slides in the spiral groove 75 provided on the inner wall of the knurled cylindrical rod 74 and wraps around the plurality of compression-type annular hermetic elastic bodies 76 rotates in the valve body 20. By reciprocating in the 71 direction, cleaning water feed to the cleaning water jetting device 1 (anal cleaning water jetting device 110), cleaning water jetting device 2 ( Three-stage switching of washing water feed to the water discharge pipe opening 62 for the purified water jetting device 2 or the washing water jetting device 120 for pre-washing, and the washing water feeding to the washing water jetting device 3 (the local washing water jetting device 130) It was made possible to operate.
In order to improve productivity and durability, it is preferable to apply grease or the like to the protrusion 72 of the rotating rod 71, the spiral groove 75, each compression-type annular hermetic elastic body, and the like.
[0024]
In the valve body 20, since the washing water jetting operation request by the operation switch or the like is automatically switched in three stages, the electric motor 80 includes an electric motor 80 so that one end of the rotary rod 71 can be driven to rotate. A drive gear 81 (for example, nylon resin) is provided, a driven gear 82 (for example, nylon resin) is provided at one end of the rotary rod 71, and fixed with a fixing screw 83 (for example, a stainless tapping screw). This is an electric four-way valve 10 for a washing water jetting device.

The electric motor 80 (including a speed reducer) may be surrounded by a waterproof cover or the like in order to protect it from humidity and bromine (ammonia etc.).
[0025]
As an example, an optical (photoelectric) encoder (for example, a shaft) is used for the spool valve 70 to accurately stop and move (improve repeatability) at each of the water discharge pipe openings [three] for the cleaning water ejection device. It is preferable to use a motor 80 with a speed reducer incorporating a built-in encoder, rotary encoder, etc., a stepping motor with a speed reducer, or the like.
Alternatively, a magnet or the like is embedded in an arbitrary position of the spool valve 70, and a magnetic detection device is disposed in an arbitrary position of the valve body 20. It is good to stop the movement accurately in [3].
The magnetic detection device (magnetic sensing element) includes, for example, a reed switch, a Hall IC, a magnetic resistance, a coil, and the like, and is usually referred to as a normally open contact (a contact or make contact) of a glass tube enclosed reed contact type. ) Reed switches are frequently used. A Hall IC may be advantageous in terms of cost and shape.
[0026]
As a reference, the electric four-way valve 10 for the washing water jetting device does not have a water stop function, so a water stop valve (electromagnetic water supply valve) that stops the water before the inflow opening 42 (front stage). Etc. are necessary. Also, if there is dust or foreign matter, the compression-type annular hermetic elastic body is easily damaged, so the cleaning water dust or foreign matter is removed with a filter, strainer, etc. in front of the inflow opening 42. It is necessary to keep it.
When the discharge water flow rate of the cleaning water is arbitrarily adjusted with a dial or the like, a flow rate adjusting device or the like is preferably provided in front of (in front of) the inflow opening 42.
[0027]
Alternatively, in the valve body 20, the three-stage switching operation is performed without using electricity (manually), so that the one end of the rotary rod 71 can be rotationally driven by the rod 90 (for example, ABS resin). One end of the moving rod 71 is provided with a rod 90, which is fixed with a fixing screw 91 (for example, a stainless tapping screw) and covered with a small screw lid 92 (for example, ABS resin). This is a manual four-way valve 12 for use.
[0028]
As a reference, since the manual four-way valve 12 for the washing water jetting device does not have a water stop function, a stop valve mechanism for stopping the washing water is required in front of the inflow opening 42 (front stage). . In a local cleaning device or the like that does not use electricity, a rotation transmission mechanism or the like that opens and closes the water stop valve mechanism or the like in conjunction with the rotation of the rod 90 may be provided. Also, if there is dirt or foreign matter, the compression-type annular hermetic elastic body is easily damaged, so a filter, strainer, etc. are provided in front of the inflow opening 42 and a mechanism for opening and closing the water stop valve. It is necessary to remove cleaning water debris and foreign matter.
When the discharge water flow rate of the cleaning water is arbitrarily adjusted with a dial or the like, a flow rate adjusting device or the like is preferably provided in front of (in front of) the inflow opening 42.
Further, in order to obtain a smooth click feeling (clicking, clicking and locking at a specified position with the click), as an example, a plurality of recesses are provided on the end face of the valve operating body 30, and A roller (for example, brass) and a disc-shaped plate spring (for example, a stainless steel plate) are attached to a screw with a screw (for example, a stainless tapping screw), and the recess and the roller are slid. And it is good to fit the big collar cover 93 (for example, ABS resin) in the collar 90 so that this mechanism cannot be seen from the outside.
[0029]
In detail, the through-hole of the inflow opening 42 provided in the one end portion side of the valve switching body 40 or the one end portion side inner peripheral wall of the valve operating body 30 damages the compression-type annular sealing elastic body 76 of the spool valve 70. Chamfered so as not to attach.
By doing so, the durability of the compression-type annular hermetic elastic body 76 is different by 10 to 50 times or more, so it is recommended to chamfer it.
[0030]
In order to enable the chamfering, the valve main body 20 is divided into a valve operating body 30 and a valve switching body 40.
[0031]
Further, the peripheral edge of the inner peripheral wall of the connecting ring 50 was chamfered so as not to damage the compression-type annular sealing elastic body 76 of the spool valve 70.
[0032]
Conventionally, there are many spool valves in which the swivel rod and the knurled cylindrical rod slide in the air. However, the knotted cylindrical rod equipped with a large sliding O-ring is watertight and watertight. Since there is a problem, in order to improve this, one end of the rotary rod 71 is pivotally supported by the valve operating body 30, and the knotted cylindrical rod 74 is provided by the water discharge pipe opening member 60 for the washing water jetting device 2. Is supported by a sliding shaft (when the shaft is supported at both ends of the spool valve 70, rattling or the like is reduced).
In order to improve productivity and durability, grease (for example, petroleum jelly) or the like is preferably applied to the shaft support portion, the compression-type annular sealed elastic body, or the like.
[0033]
Further, the injection-molded resin member was examined so that the pivot rod 71 and the knurled cylindrical rod 74 can slide both in air and in water. The rotary rod 71 and the cylindrical rod 74 with knots are usually formed of different injection molded resin members, but inevitably, for example, the same polyacetal resin may be used. However, in the case of a homogeneous member, the number of repeated reciprocating slides in a reliability test or the like is often limited to 50,000 times.
[0034]
Specifically, in order to improve the durability of sliding between the rotating rod 71 and the cylindrical rod 74 with a knot, the rotating rod 71 is formed of carbon fiber-containing polyacetal resin. As a result, the durability has been dramatically improved, and the number of repeated reciprocating slides in a reliability test or the like has cleared 500,000 times or more.
[0035]
In terms of operation (soft), the motor 80 or the heel 90 is rotated so that the washing water sent from the inflow opening 42 always goes to the washing water ejection device 1 (anus washing water ejection device 110) during standby. The spool valve 70 may be moved (fixed position 2).
By carrying out like this, for example, it can be drained from the washing water ejection apparatus 1 until the first cold warm water becomes warm water suitable for local washing.
[0036]
Alternatively, the electric motor is configured so that the washing water sent from the inflow opening 42 always goes to the washing water ejection device 2 (the water discharge pipe opening 62 for the washing water ejection device 2 or the pre-washing washing water ejection device 120) during standby. The spool valve 70 may be moved (fixed position 1) by rotating the 80 or the rod 90.
By carrying out like this, for example, it is possible to drain water from the washing water ejection device 2 until the first cold hot water becomes hot water suitable for local washing.
In addition, it is possible to clean the nozzle holes and the like of the anus cleaning water spray device and the local cleaning water spray device simultaneously with the cleaning water spray operation request by the operation switch.
[0037]
Alternatively, during standby, the motor 80 or the rod 90 is rotated to move the spool valve 70 so that the wash water sent from the inflow opening 42 always goes to the wash water jetting device 3 (local wash water jetting device 130) ( A fixed position 3) should be used.
By carrying out like this, for example, water can be drained from the washing water ejection device 3 until the first cold hot water becomes hot water suitable for local washing.
