It is also possible to form a path in the second disk 30 or in the housing 12.

  The operation of the embodiment will be described below.

  In the above configuration, the position of the cleaning water supply flow path 22 of the first disk 20 is changed from the position of the nozzle cleaning slit 31a in the initial state according to the cleaning mode selected by the user using the human body local cleaning device 10. When the second disc 30 moves to a selected position of the selected human body local cleaning slits 32, 33, 34, and the cleaning water flows, the cold water drainage in the human body local cleaning nozzle 60 is started.

  After removing the cold water from the human body local cleaning nozzle 60, the position of the cleaning water supply flow path 22 of the first disk 20 is adjacent to the selected position of any of the human body local cleaning slits 32, 33, 34 of the second disk 30. The human body moves to the position of the cleaning slit 31a or 31b, the cleaning water circulates through the communication passage 41 in the packing 40, and flows out of the nozzle cleaning water discharge part 70 to correspond to the selected cleaning mode. The local cleaning nozzle 60 is cleaned. At this time, the human body local cleaning nozzle 60 corresponding to the selected cleaning mode can be cleaned until it moves from the storage position (omitted) to the washing position (omitted).

  After the selected human body local cleaning nozzle 60 moves to the cleaning position, the position of the cleaning water supply flow path 22 of the first disk 20 is selected from the position of either the nozzle cleaning slit 31a or 31b of the second disk 30. Moved to any position of the human body local cleaning slits 32, 33, 34, and moved to any position of the flow paths 32a, 33a, 34a according to the strength of the water pressure setting. By flowing, the cleaning water is ejected from the human body local cleaning nozzle 60.

  For example, when the user selects a mode corresponding to “powerful cleaning”, the position of the cleaning water supply flow path 22 of the first disk 20 is changed from the position of the nozzle cleaning slit 31 a of the second disk 30 to the human body local cleaning slit. By moving to the position 32 and circulating the cleaning water, the cooling water drainage in the powerful cleaning nozzle 61 is started (FIG. 5B).

  After removing the cold water from the powerful cleaning nozzle 61, the position of the cleaning water supply flow path 22 of the first disk 20 is moved to the position of the nozzle cleaning slit 31b adjacent to the human body local cleaning slit 32 of the second disk 30 and cleaned. Water flows through the communication passage 41 in the packing 40, and the powerful cleaning nozzle 61 is cleaned through the nozzle cleaning water discharge section 70 (FIG. 5C).

  After the cleaning of the powerful cleaning nozzle 61, the position of the cleaning water supply flow path 22 of the first disk 20 is moved from the position of the nozzle cleaning slit 31b of the second disk 30 to the position of the human body local cleaning slit 32. Wash water is ejected from the powerful washing nozzle 61 by circulating water.

  Further, when the human body local cleaning device 10 is started and stopped, the cleaning water supply flow path 22 of the first disk 20 communicates with the nozzle cleaning slit 31a of the second disk 30 and the first disk 20 is cleaned. The water discharge recess 24 is located at a position where the drain slit 35 of the second disk 30 and the flow paths 32b, 33b, 34b communicate with each other.

  Hereinafter, effects of the embodiment will be described.

  In the above operation, the second disk 30 is provided with a nozzle cleaning slit 31a or 31b at a location adjacent to at least one of the human body local cleaning slits 32, 33, and 34. Therefore, when the first disk 20 is rotated to move the position of the cleaning water supply flow path 22 from the position of the nozzle cleaning slit 31a or 31b to any position of the human body local cleaning slits 32, 33, 34. The operating time can be shortened and the cleaning response can be improved.

  In particular, when “powerful cleaning” is selected in the configuration without the nozzle cleaning slit 31b as in the prior art, after the powerful cleaning nozzle 61 is drained with cold water, the nozzle moves to the position of the nozzle cleaning slit 31a, and the powerful cleaning nozzle 61 Perform cleaning. After cleaning the powerful cleaning nozzle 61, the cleaning water supply channel 22 moves from the nozzle cleaning slit 31a to the position of the human body local cleaning slit 32 for the powerful cleaning nozzle 61. Thus, in the configuration without the nozzle cleaning slit 31b, it takes 1.5 seconds for the cleaning water supply flow path 22 to move from the position of the nozzle cleaning slit 31a to the position of the human body local cleaning slit 32. .

  On the other hand, in the present embodiment, when the nozzle cleaning slit 31b is provided, the powerful cleaning nozzle 61 is moved to the position of the nozzle cleaning 31b after the cold water is drained, and then a series of operations are performed. When the nozzle cleaning slit 31b is provided, it takes 0.6 seconds for the cleaning water supply flow path 22 to move from the position of the nozzle cleaning slit 31b to the position of the human body local cleaning slit 32. That is, the operation time of the first disk 20 can be shortened by 0.9 seconds.

  In addition, the amount of operation of the first disk 20 can be reduced, wear of the contact surface between the contact part 21 of the first disk 20 and the second disk 30 can be reduced, and the occurrence of failure of the apparatus can be suppressed.

  The cleaning water supply flow path 22 of the first disk 20 does not move from the position of the human body local cleaning slit 32 of the second disk 30 to the position of the nozzle cleaning slit 31a having a large rotation angle, and the cleaning water supply flow path 22 It moves from the position 32 to the position of the nozzle cleaning slit 31b having a small rotation angle. Therefore, the operation time for rotating the first disk 20 to move the position of the cleaning water supply flow path 22 from the position of the nozzle cleaning slit 31a or 31b to the position of the human body local cleaning slits 32, 33, 34 is shortened. Therefore, sufficient cleaning time for the human body local cleaning nozzle 60 can be obtained, and the nozzle cleaning effect can be improved.

  In particular, when “Powerful cleaning” is selected, the operation time can be shortened by 0.9 seconds, so that the cleaning time is longer than the conventional technology by 0.9 seconds until the powerful cleaning nozzle 61 moves from the storage position to the cleaning position. .

  In addition, since the human body local cleaning device 10 includes the packing 40 having a flow path that communicates the nozzle cleaning slits 31 a and 31 b of the second disk 30, the flow path that communicates from the nozzle cleaning slits 31 a and 31 b to the human body local cleaning nozzle 60. The cleaning water can be supplied efficiently without requiring a plurality of water. Further, by providing the human body part cleaning nozzle 60, the nozzle cleaning water discharge unit 70, and the flow path for supplying the cleaning water to the drain 80 in the packing 40 using rubber or soft plastic, the second disk 30 using a hard material is provided. Workability is better than when a flow path is provided, and costs can be reduced.

  In this embodiment, the case where “powerful cleaning” of the human body local cleaning device 10 is selected as an example is mainly exemplified. However, even if “mild cleaning” is selected, the same effect can be obtained and a series of cleaning operation times can be obtained. Can be shortened.
