Thereafter, in order for water to be supplied to the cleaning nozzle 482, the rotary disk 220 is further rotated counterclockwise as shown in FIG. 7C. The selection hole 223 of the rotary disk 220 is communicated with the communication hole 214a connected to the communication hole 214 'and the groove 214 of the fixed disk 210, The groove 226 connects the communication hole 211 communicating with the hot water inflow portion 121 to the communication hole 215a connected to the groove 215.

The raw water flowing into the raw water inflow portion 111 is communicated with the selection hole 223 and the communication hole 214 'and / or the communication hole 214a to move to the heated raw water supply portion 123, The heated water which has been introduced into the heating member 460 through the opening 123a and heated and then flows into the hot water inflow part 121 through the hot water inflow opening 121a. The hot water that has passed through the communication hole 211 of the fixed disk 210, the central groove 224 of the guide groove 226 formed on the lower surface of the rotary disk 220, and the extended groove 225 sequentially passes through the fixed disk 210, Is supplied to the cleaning water supply unit 125 through the communication hole 215a connected to the groove 215 of the cleaning water supply port 125a and supplied to the cleaning nozzle 482 through the cleaning water supply port 125a.

The hot water heated by the heating member 440 flows into the hot water inflow portion 121 immediately after the raw water flowing into the raw water inflow portion 111 moves to the heating source supply portion 123 and is discharged to the heating member 440 side. And is supplied to the cleaning nozzle 481 through the cleaning water supply part 125. 7C, the selection hole 223 is shown as being simultaneously connected to the communication hole 214a connected to the auxiliary communication hole 214 'and the groove 215. However, when the guide hole 226 is communicated with the communication hole 215a, The selection hole 223 is communicated with the auxiliary communication hole 214 'to form a pressure in the passage (heating hot water supply line 430) connected to the heating member 440 in advance so that the guide groove 226 The hot water passing through the heating member 440 flows into the hot water inflow part 121 as soon as it is communicated with the communication hole 215a. At this time, the heating member 440 may be an instantaneous heating device instantaneously heated as the inflow water flows, or may be a hot water tank for heating and storing the inflow water.

It is preferable that the groove 214 connected to the communication hole 214a is gradually widened toward the other side in order to increase the spraying of the washing water as the rotating disk 210 rotates. That is, when an excessive amount of washing water is injected from the cleaning nozzle 482 at the beginning of the washing water injection, the user may feel uncomfortable. Therefore, it is necessary that the width of the groove 214 is gradually widened so that a small amount of washing water is initially sprayed .

7D, when the rotary disk 220 further rotates to reach the position where the width of the groove 214 reaches the widest position, the spray amount of the washing water becomes maximum and the rotation amount of the rotary disk 220 Angle) of the washing water to adjust the amount or strength of the washing water to be sprayed.

After the cleaning function is completed, the rotary disk 220 rotates in the clockwise direction to return to the initial state shown in FIG. 7A through the nozzle cleaning position in FIG. 7B. In this process, do.

In order to perform the bidet function, the rotary disk 220 may be rotated clockwise at an initial position of the rotary disk 220 shown in FIG. 7A. The rotation of the rotary disk 220 in the clockwise direction is the same as that of the rotation of the rotary disk 220 except that the selection hole 221 of the rotary disk 220 coincides with the communication hole 212 of the fixed disk 210, Since the detailed process is similar to the cleaning function, detailed description is omitted.

As described above, since the bidet passage switching valve 100 according to the embodiment of the present invention uses two selection holes 221 and 222 for implementing the nozzle cleaning operation, the rotary disk 220 performs the cleaning / The selection holes 221 and 222 and the communication hole 212 are communicated with each other in the process of returning to the original position regardless of the rotation in any direction for the purpose of cleaning the nozzle.
