However, in the former publication, although it is possible to eject in a wide range and in two forms of one point concentration, in order to add more forms, the nozzle body For example, it is necessary to insert a tube or the like therein and newly provide a jet hole at the end thereof so as to provide the nozzle body with another flow path. Such an increase in the flow path results in an increase in the outer diameter of the nozzle body and the bulk of the whole, and requires a large design change in order to avoid interference with devices around the nozzle device.

Further, in the latter publication, since a plurality of nozzle bodies are arranged, not only the apparatus including its drive system becomes complicated, but also the area occupied by the nozzle apparatus becomes significantly large. .

As described above, although the conventional structure has the function of ejecting the cleaning water in different forms to one cleaning target, it is not possible to suppress the bulk of the nozzle device, and it is possible to make it compact and to have an external appearance. Is an obstacle in terms of improvement.

The problem to be solved in the present invention is to provide a local cleaning apparatus which can reduce the bulk of the apparatus while enabling cleaning of a plurality of cleaning water on one cleaning target. is there.

[0009]

According to the present invention, cleaning water supplied from a water supply source is introduced into a flow path of a cleaning nozzle, and the cleaning water is directed to a local portion from an ejection portion provided at a substantially tip portion of the cleaning nozzle. In the local cleaning device for ejecting, a plurality of ejection parts including the ejection holes are arranged corresponding to substantially the same cleaning target position of the human body local part, and an independent cleaning water supply path communicating with the plurality of ejection parts is provided. It is characterized in that it is formed by partitioning in the flow path of the cleaning nozzle.

In such a structure, a jet portion corresponding to a cleaning target position different from the plurality of jet portions is provided, and
A configuration may be adopted in which a washing water supply passage to the jet portion is provided and three or more washing water supply passages are formed by partition walls in the passage of the washing nozzle.

One of the supply paths of the cleaning water divided by the partition wall is the first flow path that penetrates the cross section of the cleaning nozzle, and the flow path toward the remaining ejection portion is the first flow path. It can be divided into the surrounding space.

Further, a cleaning water supply unit capable of supplying cleaning water in any combination by arbitrarily selecting a flow path from a water supply source with respect to independent cleaning water supply paths respectively directed to a plurality of jetting portions. It may be provided. In this case, the wash water supply unit may be provided with a flow rate adjusting mechanism capable of adjusting the flow rate for each of the wash water supply paths.

Further, it is possible to set the jetting speed of the washing water from one of the plurality of jetting holes to the jetting speed of the washing water from the other jetting hole to be large.

Further, the jetting portion communicates with a first jetting hole communicating with one of the washing water supply passages and another washing water feeding passage and extends around the first jetting hole. You may make it provide with the arrange | positioned 2nd ejection port.

Further, the cleaning nozzle includes a main body having a cleaning water supply passage formed therein, and a connector connected to a base end of the main body to connect a flow passage between a plurality of supply passages of the cleaning water from the water supply source. A head formed with an internal flow path that is connected to the tip of the main body and independently communicates the interior of the main body with a plurality of supply paths for the cleaning water; And a jet plate for communicating one group of jet holes to each of the above.

[0016]

BEST MODE FOR CARRYING OUT THE INVENTION When, for example, the anus is to be washed, a plurality of jets of jets are set for the washing point by arranging a group of jetting portions having jet holes so as to correspond to the position of anal washing. The cleaning water can be jetted by switching to the cleaning water from the hole. The bulk of the washing water supply passage can be prevented by forming the washing water supply passage that goes independently to each of the ejection holes by the partition wall in the washing nozzle.

By making the supply path of the washing water a first flow path and a flow path which is formed in a ring around the first flow path and is partitioned,
It is possible to compactly arrange the flow paths toward the ejection holes in the cleaning nozzle.

In the case where the washing water supply unit is provided, it is possible to set the washing water jetting pattern from the jetting holes to an optimum washing mode by setting the combination of the jetting holes. In addition, the strength of the wash water can be added.

The first jet hole and the second circular passage around the first jet hole
In addition, the cleaning water to be sprayed can be made into concentric converged streamlines, and the first and second
Since the area occupied by the ejection holes can be reduced, the nozzle device can be downsized. Then, by making the flow rate of the cleaning water from the first ejection hole larger than that from the second ejection hole, when the cleaning water is ejected simultaneously from these first and second ejection holes, The wash water from the second jet hole blocks the wash water from the spout of No. 1 from splashing from the local part, and the degree of splash of the wash water after hitting the local part is small. Become.

Further, in the case where the cleaning nozzle is composed of the connector, the main body, the head, and the ejection plate, these members can be manufactured in shapes suitable for their functions, and the manufacturing itself is simplified.

A partition wall 10g is provided inside the housing 10a at a position between the first outflow pipe 10d and the third outflow pipe 10f, and the rotor 14 is rotatably pierced through the partition wall 10g in a watertight manner. ing. The partition 10g divides the interior of the housing 10a into two chambers that communicate with the inlets 10b and 10c, respectively. That is,
Since the first and second outflow pipes 10d and 10e are in communication with the first and second flow paths 4a and 4b of the main body 4 of the respective cleaning nozzle 2, the room in which the inflow port 10b is in communication is for anus cleaning. On the other hand, since the third outflow pipe 10e communicates with the third flow passage 4c, the room side with which the inflow port 10c communicates corresponds to a water supply channel for bidet.

The rotor 12 directly connected to the output shaft of the drive motor 11 is of the spool valve type and has the first to third outflow pipes 1.
The first valve element 12a, the second valve element 12b, and the third valve element 12c are formed at intervals corresponding to the communicating portions with 0d to 10f, respectively, in the axial direction. Each of the first to third valve bodies 12a to 12c has its peripheral surface sealed by a packing 10h provided on the inner circumference of the housing 10a in a portion communicating with the first to third outflow pipes 10d to 10f.

2b-1 is inscribed on the peripheral surface from the notch portions 12a-2, 12b-2, respectively, and these notch portions 12a-2, 1
The side closer to 2b-2 has a wider channel width and a larger depth.

Further, the third valve body 12c has the same shape as the first valve body 12a, and the flow passage groove 12c-1 and the cutout portion 12c-2 are formed on the peripheral surface of the third valve body 12c. The posture of the third valve body 12c is the same as that of the first valve body 12a.

12 to 14 show the rotational posture of the rotor 14, the inlets 10b and 10c, and the first to third outflow pipes 10d.
It is a schematic diagram for explaining water stoppage and water supply by a positional relation with 10f.

FIG. 12 shows the packing 10h in a water-stopped state where the outer peripheral surfaces of the first to third valve bodies 12a to 12c are located at the base ends of the first to third outflow pipes 10d to 10f.
(See FIG. 11), all the flow paths from the switching / flow control unit 10 to the cleaning nozzle 2 are blocked.

FIG. 13 shows a state in which the rotor 14 is rotated in the direction of the arrow in the drawing from the water stop position when only the inlet 10c side is in communication with the hot water tank 52 hot water outlet by the switching unit 9. . By the rotation of the rotor 13 as described above, the notch 12 is formed at the flow path inlet to the third outflow pipe 10f side.
c-1 comes to face, and as the rotation angle of the rotor 14 increases, the flow passage groove 12c-1 becomes larger.
The supply flow rate to the third flow path 4c of the cleaning nozzle 2 also gradually increases, and becomes the maximum flow rate when the notch 12c-2 faces the base end of the third outflow pipe 10f. The first valve body 1
The posture of 2a is also changed in the same manner, but the switching unit 9 keeps the inlet 10b side closed, so that no washing water is supplied to the first flow path 4a of the main body 4.

In FIG. 14, when only the inflow port 10b communicates with the hot water tank 52 by the switching unit 9, the cleaning water is supplied only to the first flow path 4a or the second flow path 4b of the main body 4 or both of them. This is an example.

By setting the rotor 12 in the rotation posture as shown in FIG. 9A, the flow path groove 12 of the second valve body 12b is set.
b-1 comes to face the base end side of the second outflow pipe 10e,
The washing water is supplied to the second flow path 4b of the main body 4 while gradually increasing the flow rate in proportion to the rotation angle of the rotor 12, and the cutout portion 12b-2 reaches the maximum flow rate at the position facing the second outflow pipe 10e. During setting up to such a maximum flow rate, the first
If the flow path groove 12a-1 of the valve body 12a is not exposed to the base end of the first outflow pipe 10d, the cleaning water will not flow to the second end of the main body 4.
It is supplied only to the flow path 4b, and in FIG.
The washing water is sprayed from.

When the rotor 12 is further rotated, as shown in FIG.
4 (b), the flow path groove 12 of the first valve body 12a
a-1 gradually comes to face the base end side of the first outflow pipe 10d, and the respective flow passage grooves 12a-1 and 12b-1 of the first and second valve bodies 12a and 12b simultaneously form the first and second passages. It communicates with the outflow pipes 10d and 10e. Therefore, the cleaning water is simultaneously supplied to the first and second flow paths 4a and 4b of the main body 4, and the cleaning water is sprayed from the first and second ejection holes 6a and 6b in FIG. Since the flow passage grooves 12a-1 and 12b-1 are formed in opposite directions and the groove widths and the depths thereof are also opposite, it is possible to change the rotation angle of the rotor 12 so that the first
When one of the ejection holes 6a and the second ejection hole 6b is large, the other is decreased, and the flow rates of the wash water from the first and second ejection holes 6a and 6b are changed at the same time. You can

Further, by further rotating the rotor 12,
(C), the second valve body 12b has its peripheral surface in close contact with the packing 10h to be in a water-stopped state, and the flow passage groove 12a-1 and the cutout portion 12a-2 of the first valve body 12a are The first outflow pipe 10d comes to face. Therefore, the body 4
The cleaning water is supplied only to the first flow path 4a, and the cleaning water is ejected from the first ejection holes 6a in FIG.

FIG. 15 shows an example of a remote controller type operation panel for operating the nozzle device 1 and other functional parts.

The operation panel 30 has a first cleaning switch 31,
The second cleaning switch 32 and the third cleaning switch 33 are provided, and a stop switch 34 for stopping the operation of each functional unit is provided. Also, these switches 31
34 to 34, position setting switches 35a and 35b of the main body 3 of the nozzle device 2 are provided, as is also attached to the conventional sanitary washing toilet seat, and a water pressure adjusting switch 36a for adjusting the water pressure of the washing water is further provided. , 36b are provided.

When the first cleaning switch 31 is turned on, the changeover unit 9 uses the built-in two-way valve to introduce the inflow port 10.
The rotor 12 of the switching / flow control unit 10 operates so as to open the flow path to the side b, and is set to the state of FIG. 14 (c). Therefore, the wash water from the warm water tank 52 is ejected from the first ejection port 6a of the ejection plate 6 shown in FIG. 8 via the first port 3a and the first flow path 4a.

When the second switch 32 is turned on, the switching unit 9 is maintained as it is, and the switching
The rotor 12 of the flow control unit 10 rotates to the posture shown in FIG. Thereby, the flow path groove 1 of the second valve body 12b
2b-1 and the cutout portion 12b-2 are used for the second cleaning water.
The cleaning water is supplied to the port 3b and is sprayed from the second jet hole 6b of the jet plate 6 through the second flow path 4b of the main body 4.

Here, by setting the flow rate of the cleaning water ejected from the first ejection holes 6a to be higher than that when the second ejection holes 6b are used, the cleaning water when the first ejection holes 6a is used. Can be made stronger than that of the washing water from the second ejection holes 6b. Then, as shown in FIG. 8B, the first ejection holes 6a are a group concentrated in the center, whereas the second ejection holes 6b are annularly arranged around the group of the first ejection holes 6a. Therefore, the cleaning water from the second ejection holes 6b gently hits the cleaning target. Also in the example of FIG. 9, since the first ejection hole 7a of the ejection plate 7 has a large inner diameter, it is possible to similarly strengthen the cleaning force of the cleaning water from the first ejection hole 7a. it can.

As described above, when the first cleaning switch 31 is turned on, in the example of FIG. 8, the cleaning water is ejected from the first ejection hole 6a with a strong force, whereas when the second cleaning switch 32 is turned on. It is possible to spout the wash water softer than this. Therefore, by switching the anus to one of the first and second ejection holes 6a and 6b for cleaning, it is possible to use the cleaning water in two different spray modes.

Further, the first cleaning switch 31 and the second cleaning switch 32 are simultaneously turned on, or the first cleaning switch 31 is first turned on and the second cleaning switch 32 is turned on during its use, or When the first cleaning switch 31 is turned on while the second cleaning switch 32 is turned on, the rotor 12 is set to the rotation posture shown in FIG. 14 (b). In this state, the first and second valve bodies 12a, 12
Since b respectively opens the flow paths to the first and second outflow pipes 10d and 10e at the same time, the cleaning water is simultaneously supplied to the first and second flow paths 4a and 4b of the main body 4. Therefore, the cleaning water is discharged toward the cleaning target from the first and second ejection holes 6a and 6b of the ejection plate 6.

In this way, the first and second cleaning switches 3
By the operations of 1 and 32, the cleaning water is ejected from either the first ejection hole 6a for strong cleaning or the second ejection hole 6b for gentle cleaning, or the first and second ejection holes 6 are ejected.
Whether it will be ejected from both a and 6b at the same time, a total of 3
It is possible to switch to the spouting form of street wash water.

Further, in addition to such switching of each cleaning mode, when the cleaning water is simultaneously ejected from the first and second ejection holes 6a and 6b, the rotation angle of the rotor 12 is adjusted to The flow rates of the wash water from the second ejection holes 6a and 6b can be changed so as to increase or decrease. This is because the flow passage grooves 12a-1 and 12b-1 of the first and second valve bodies 12a and 12b of the rotor 12 are carved in opposite directions in the circumferential direction.
It is possible to decrease the ejection amount from the ejection hole 6a and increase the ejection amount from the second ejection hole 6b, or vice versa. For such an operation, the water force adjusting switches 36a and 36b are used. For example, when the ejection amount from the first ejection hole 6a is increased, the water force adjusting switch 36a is continuously pressed, and when the ejection amount is decreased, the water force adjusting switch 36a is pressed. By setting the rotation angle of the rotor 12 by continuously pressing 36b, the first and second ejection holes 6
It can be adjusted as a relationship in which the respective ejection amounts from a and 6b increase or decrease with each other.

When the stop switch 34 is turned on, the rotor 12 rotates so as to assume the posture shown in FIG. 12, and the peripheral surfaces of the first to third valve bodies 12a to 12c are respectively packed 10h.
The water is stopped in close contact with. Then, the third cleaning switch 33
When turned on, the main body 4 of the nozzle device 1 advances to a position where the stroke is slightly longer than in the case of anus washing, and the two-way valve of the switching unit 9 communicates only with the inflow port 10c in FIG. The cleaning water is supplied to the room where the third valve body 12c partitioned by the partition wall is located. Then, the rotor 12 rotates to the posture shown in FIG. 13, and the flow passage groove 12c-1 and the cutout portion 12c-2 of the third valve body 12c are rotated.
Is communicated with the flow path on the side of the third outflow pipe 10f, and the cleaning water is ejected from the third ejection hole 6c in the example of FIG. 8 via the third port 3c and the third flow path 4c and used as a bidet. be able to.

In the above example, the switching unit 9 and the switching / flow adjusting unit 10 of the wash water supply unit 8 select the first to third ejection holes 6a to 6c and adjust the flow rate. It is possible to similarly change or combine the jetting form of the washing water by the flow path configuration instead of this, and examples thereof are shown in FIGS. 16 and 17, respectively.

In FIG. 16 (a), the flow rate adjusting valve 20 is arranged on the hot water tank 52 at the hot water outlet side, and the nozzle device 1 is used.
Electromagnetic valves 21a, 21b, and 21c for opening and closing the flow paths are arranged in the respective flow paths toward the first to third ports 3a to 3c. Then, as shown in the above example, the first to third ejection holes 6 are combined by the combination of the flow rate adjustment by the flow rate adjusting valve 20 and the opening / closing operation of the electromagnetic valves 21a to 21c.
The washing water can be jetted as any one or a combination of two or more of a to 6c. In particular, the solenoid valves 21a-21
If an operation is performed such that all c are opened, anus washing and bidet are possible at the same time.

Further, in FIG. 9B, the distribution valve 22 is arranged downstream of the flow rate adjusting valve 20 in place of the solenoid valve, and the flow paths to the first to third ports 3a to 3c are arranged in this distribution valve. 22 is an example of connection to 22. It suffices that the distribution valve 22 can connect the flow passages by only one of the three flow passages on the downstream side or a combination of two or more passages, and by selecting and combining such flow passage systems. , The first to third ejection holes 6a to
It is possible to eject cleaning water having different cleaning modes using 6c.

In FIG. 17A, the flow passage from the hot water tank 52 outlet is divided into three systems, and each system has a solenoid valve 23a to 25a for opening and closing the flow passage and a flow control switching valve 23b. 25b is incorporated, and the first and second ports 3a and 3b in the previous example are connected to the respective downstreams of the flow control switching valves 23b to 24b.
A flow path to the third port 3c is connected to the remaining flow control switching valve 25b.

In this example, for example, the solenoid valves 23a, 24
By opening a at the same time and adjusting the flow rate of the wash water by the downstream flow control switching valves 23b and 24b, respectively, the flow rate and the water force of the wash water from the first and second ejection holes 6a and 6b can be varied.
