It may be made of a stepped groove formed to have a step, so that the washing water flowing through the first, second, second, third, fourth extension (243a, 243b, 243c, 243d) is the first, second, third, fourth extension After hitting one surface (upper surface in FIG. 8) of the 243a, 243b, 243c, and 243d, the first and second straight stream communicating portions 241a and 242a and the first and second wide stream communicating portions 241b and 242b flow in. The cleaning nozzle 142 and the bidet nozzle 144 are supplied.

As such, since the flow path of the washing water is bent, the washing water flows into the first, second, third, and fourth extension parts 243a, 243b, 243c, and 243d to be supplied to the washing nozzle 142 and the bidet nozzle 144. The flow rate of the washing water to be reduced can be reduced.

On the other hand, an extension groove 244 is formed in the second extension portion 243b to finely control the flow rate of the washing water supplied to the wide water flow passage 142d of the cleaning nozzle 142.

Since the extension grooves 244 are formed to have a narrower width than the first, second, third and fourth extension parts 243a, 243b, 243c, and 243d, the flow rate of the washing water flowing through the extension grooves 244 is fine. can do.

Referring to the operation of the second flow path communication member 240, first, when the washing water is injected into the straight stream from the cleaning nozzle 142, the washing water is the second flow path opening and closing member 250 as shown in Figs. 2) flows only through the first linear water flow communicating portion 241a or the first extension portion 243a of the second flow passage communicating member 240 opened by.

The washing water flows through the first and second extension parts 243a and 243b.

That is, when the washing water is injected into the wide water stream having an ellipse shape from the washing nozzle 142, the washing water flows through the first extension part 243a and the second extension part 243b of the second flow path communication member 240.

On the other hand, when it is desired to change the number of stages of the wide water flow injected from the cleaning nozzle 142, the first extension portion (243a) and the second of the second flow path communication member 240 opened by the second flow path opening and closing member 250 By changing the flow rate of the washing water flowing through the extension portion 243b, it is possible to change the stage of the wide water stream having an ellipse shape.

That is, as shown in FIG. 12, when the second extension part 243b is opened wider by the second flow path opening and closing member 250, the flow rate of the washing water flowing through the second extension part 243b is increased. The flow rate of the washing water flowing through the first extension portion 243a is reduced, and thus the wide water stream injected from the washing nozzle 142 is spread more widely. In addition, as shown in FIG. 11, when the first extension part 243a is opened wider by the second flow path opening / closing member 250, the flow rate of the washing water flowing through the second extension part 243b is reduced and thus the first flow rate is increased. The flow rate of the washing water flowing through the extension 243a is increased, and thus, the washing water is sprayed from the washing nozzle 142 to a narrower area.

However, since the extension grooves 244 are formed in the second extension part 243b, the flow rate of the washing water flowing through the second extension part 243b may be more precisely controlled. Accordingly, the number of stages of the elliptical wide water flow injected from the cleaning nozzle 142 can be more precisely controlled.

Meanwhile, a locking jaw (not shown) is formed in the second housing 220 so as to support the edge of the second flow path communicating member 240. In addition, the second flow path communication member 240 is supported by the latching jaw (not shown) and the cross-shaped rib 227 so that the second flow path communication member 240 is deformed even though hydraulic pressure acts on the second flow path communication member 240. Can be prevented.

In addition, a circular ring-shaped gasket 247 is installed in the second flow path communication member 240 to seal a gap between the locking jaw and the second flow path communication member 240. In addition, the gasket 247 is a cross-shaped cross portion 247a is formed to cross the center portion to seal the gap between the second flow path communication member 220 and the cross rib 227.

In addition, a cross-shaped groove 246 is formed on one surface of the second flow path communication member 240 so that the cross-shaped cross portion 247a of the gasket 247 is fitted thereto.

The second flow path opening and closing member 250 is rotatably installed in the second housing 220 so that the first and second linear water flow communication portions 241a and 241b and the first and second wide water flow communication portions 242a and 242b. One or more of the above-described extension part 243 is selectively opened and closed.

That is, the second flow path opening and closing member 250 may open any one of the pair of compartments 221 and 222 or the pair of compartments 221 and 222 in communication with the cleaning nozzle 142.

On the other hand, the second flow path opening and closing member 250 is in surface contact with the second flow path communication member 220 and the first and second linear water flow communication portion (241a, 241b) and the first and second wide water flow communication portion 242a, 242b), and a disk portion 251 having an opening and closing groove 252 for selectively opening and closing the extension portion 243 may be provided.

That is, the first and second straight stream communicating portions 241a and 241b, the first and second wide stream communicating portions 242a and 242b, and the extension part according to the position where the opening and closing groove 252 of the disk portion 251 is disposed. One of the openings 243 may be opened to adjust the flow path of the washing water and at the same time change the flow rate.

In more detail, as shown in FIG. 9, when the opening / closing groove 252 completely opens only the first linear water flow communicating part 241a, the washing water sprayed from the cleaning nozzle 142 is discharged into the straight water stream.

In addition, when the opening and closing groove 252 completely opens only the first extension part 243a extending from the first linear water flow communication part 241a as shown in FIG. 10, the washing water sprayed from the cleaning nozzle 142 is straight. The water is discharged into the water stream, and the washing water is discharged at a low stage (low water pressure and a small flow rate) as compared with the case where only the first straight stream communication portion 241a is completely opened.

In addition, when the opening and closing groove 252 is arranged to open a part of the first and second extensions 243a and 243b as shown in FIGS. 11 and 12, the washing water sprayed from the cleaning nozzle 142 may have an ellipse shape. The branches are discharged in the wide stream.

In addition, the number of stages of washing water injected into the wide water stream having an elliptic shape from the cleaning nozzle 142 can be changed according to the degree of opening and closing of the first extension part 243a and the second extension part 243b. Do.

That is, as shown in FIG. 11, the opening / closing groove 252 opens the first extension part 243a more than the second extension part 243b so that the flow rate of the washing water flowing into the first extension part 243a increases. In this case, the washing water injected into the wide water stream having the elliptical shape from the washing nozzle 142 is sprayed into a narrower area, and as shown in FIG. 12, the opening / closing groove 252 extends the second extension part 243b to the first extension part. When more than 243a is opened, the washing water sprayed from the washing nozzle 142 to the wide water stream having an elliptical shape is sprayed while spreading more widely.

In addition, when the opening and closing groove 252 is rotated to adjust the degree of opening the first extension portion 243a and the second extension portion 243b, an extension groove 244 is formed in the second extension portion 243b. Therefore, the flow rate of the washing water passing through the second extension part 243b can be more finely adjusted.

The second flow path opening and closing member 250 may further include a rotating part 255 that is axially coupled to the disk unit 251 and axially coupled to the drive motor 260. In addition, the disk unit 251 and the rotating unit 255 may be detachably coupled.
