In this embodiment, the movable shaft 30 three-dimensionally intersects the nozzle 2 perpendicularly when viewed from above, moves in a different direction from the nozzle 2, passes through the base plate 4 through the inverted S-shaped crank portion, and moves to the housing. It extends to the outside and can be slid by operating the movable shaft 30 from an operating portion (not shown) provided outside the housing. The warm water washing toilet seat device 1 operates the nozzles 2 and 3 toward the toilet.

  FIG. 2 is a cross-sectional view taken along the line AA of the warm water cleaning toilet seat device 1 when the nozzle body 20 is stored according to the first embodiment of the present invention. The nozzle 2 includes a cylindrical nozzle holder 10 that forms the outer surface of the nozzle 2, a nozzle body 20 that is formed inside the nozzle holder 10 and that can protrude from the nozzle holder 10 under water pressure, and a movable shaft 30 of the nozzle body 20. And a nonmagnetic return spring 22 (biasing member) that biases the metal member 21 (first magnetic body) provided on the surface facing the nozzle body 10 in a direction in which the nozzle body 20 is housed in the nozzle holder 10. Composed. The nozzle holder 10 has a water supply port 11 for supplying cleaning water to one end, an opening 12 for projecting the nozzle body 20 to the other end, and a nozzle body locking surface 13 for locking the nozzle body 20. The nozzle body 20 has a cylindrical shape, and has an enlarged portion 23 for engaging with the nozzle holder 10 at one end, a water supply port 24 for supplying cleaning water to the nozzle body 20, and a valve 25 that can be seated on the water supply port 24. And are provided. The nozzle body 20 has one end of the valve spring 26 attached to the valve 25 and seats the valve 25 on the water supply port 24, and the other end of the valve spring 26 is attached to the fixed valve spring attachment portion 27. In addition, the nozzle 28 which ejects water when operating the warm water washing toilet seat apparatus 1 is provided in the upper surface side of the front-end | tip of the nozzle main body 20. As shown in FIG. Further, the biasing force of the return spring 22 and the valve spring 26 is set so that the valve spring 26 is compressed after the return spring 22 is compressed by the pressure applied to the nozzle body 20 caused by the cleaning water. ing. Further, the resin buttocks cleaning nozzle 3 has the same structure as the nozzle 2. The permanent magnet 31 of the movable shaft 30 is provided on a surface 32 on the nozzle 2 side facing the nozzle holder 10 and the metal member 21.

  FIG. 3 is a top view of the warm water washing toilet seat device 1 when the nozzle body 20 protrudes according to the first embodiment of the present invention. FIG. 3 shows the warm water cleaning toilet seat apparatus 1 after the movable shaft 30 having the permanent magnet 31 is moved from FIG. 1, and the nozzle body 20 is moved from the nozzle holder 10 to, for example, 10 mm to 10 mm by moving the movable shaft 30 toward the nozzle 2. Project 15 mm.

  FIG. 4 is a cross-sectional view taken along the line BB of the warm water cleaning toilet seat device 1 when the nozzle body 20 protrudes according to the first embodiment of the present invention. FIG. 4 is the warm water washing toilet seat device 1 after the movable shaft 30 having the permanent magnet 31 is moved from FIG. 2, and the metal member 21 and the permanent magnet 31 are moved by the movable shaft 30 approaching the nozzle 2. The return spring 22 is compressed and the nozzle body 20 is protruded from the nozzle holder 10. Note that the distance between the metal member 21 and the permanent magnet 31 is determined as appropriate in relation to the spring constant of the return spring 22 and the magnetic force of the permanent magnet 31, and the attractive force between the metal member 21 and the permanent magnet 31. Is stronger than the biasing force of the return spring 22 and can compress the return spring 22.

  The operation of the first embodiment will be described. When the cleaning water is supplied to the nozzle holder 10 from the water supply port 11, the water pressure of the cleaning water acts on the rear end surface of the enlarged portion 23 of the nozzle body 20, and the enlarged portion 23 is engaged with the nozzle body while compressing the return spring 22. The nozzle body 20 is advanced until it is locked by the stop surface 13. Then, the water pressure of the washing water pushes down the valve 25 while compressing the valve spring 26 to open the water supply port 24 so that the washing water flows into the nozzle body 20 and is ejected from the ejection port 28.

  When the supply of the washing water is stopped, the valve 25 closes the water supply port 24 by the urging force of the valve spring 26 and retreats so that the nozzle body 20 is accommodated in the nozzle holder 10 by the urging force of the return spring 22.

  When the nozzle body 20 protrudes from the nozzle holder 10 and the nozzle body 20 is cleaned from the state where the nozzle body 20 is retracted, the movable shaft 50 having the permanent magnet 51 is moved in a direction approaching the nozzle 2. When the movable shaft 30 approaches the nozzle 2, the return spring 22 is compressed by the metal member 21 being attracted to the permanent magnet 31 by the action of the magnetic force between the metal member 21 of the nozzle body 20 and the permanent magnet 31. Then, the nozzle body 20 is pulled out from the nozzle holder 10. In order to return the nozzle body 20 to the nozzle holder 10, the movable shaft 30 having the permanent magnet 31 is moved in a direction away from the nozzle 2. When the movable shaft 30 is separated from the nozzle 2, the action of the magnetic force between the metal member 21 of the nozzle body 20 and the permanent magnet 31 is weakened, and the metal member 21 is not attracted to the permanent magnet 31, thereby returning spring 22. The nozzle body 20 is retracted so as to be accommodated in the nozzle holder 10 by the urging force. The operation of the resin butt washing nozzle 3 is the same as that of the nozzle 2.

  The effect of the first embodiment will be described. When cleaning the nozzle body 20, the magnetic force is exerted by the metal member 21 and the permanent magnet 31, and the nozzle body 20 protrudes, for example, 10 mm to 15 mm in a non-contact manner, so that a tool for contacting and pulling out the nozzle body 20 becomes unnecessary. There is no problem that dirt at the tip of the nozzle adheres to the tool, and the nozzle body 20 can be pulled out and the area around the ejection port 28 can be cleaned.

  Further, since the nozzle body 20 can be pulled out (projected) from the nozzle holder 10 even if a permanent magnet is used only for the permanent magnet 31 that is the first magnetic body, a metal member is used as the second magnetic body instead of a permanent magnet. By using 21, the cost can be suppressed compared to using a permanent magnet for the second magnetic body.

In addition, since the urging member uses the non-magnetic return spring 22, it is possible to smoothly pull out the nozzle body 20 from the nozzle holder 10 without being affected by the magnetic force.

  Moreover, since the warm water washing toilet seat apparatus 1 can slide and move the movable shaft 30 in parallel with the base plate 4, it can operate in a limited space between the nozzle 2 and the base plate 4. Further, in the warm water washing toilet seat device 1, the movable shaft 30 moves in a twisting direction with respect to the sliding movement direction of the nozzle 2 (in this embodiment, the sliding movement relative to the nozzle 2 so that the movable shaft 30 intersects three-dimensionally. By doing so, the malfunction of the pulling-out operation of the nozzles 2 and 3 is suppressed. For example, when the movable shaft 30 is slid from the front in the protruding direction of the nozzles 2 and 3, the nozzle body 20 is pulled by the positional relationship between the nozzle body 20 and the magnetic bodies 21 and 31 provided on the movable shaft 30. May not be issued.

And the permanent magnet 51 repel each other, compress the return spring 42, and cause the nozzle body 40 to protrude from the nozzle holder 10. The distance between the permanent magnet 41 and the permanent magnet 51 is determined as appropriate in relation to the spring constant of the return spring 42, the magnetic force of the permanent magnet 41, and the magnetic force of the permanent magnet 51, and the permanent magnet 41 and the permanent magnet 51. The repulsive force between the two springs is stronger than the biasing force of the return spring 42, and the return spring 42 can be compressed.

  The operation of the second embodiment will be described. When the cleaning water is supplied from the water supply port 11 to the nozzle holder 10, the water pressure of the cleaning water acts on the rear end surface of the enlarged portion 43 of the nozzle body 40, and the enlarged portion 43 is engaged with the nozzle body while compressing the return spring 42. The nozzle body 40 is advanced until it is locked by the stop surface 13. Then, the water pressure of the washing water pushes down the valve 45 while compressing the valve spring 46 to open the water supply port 44 so that the washing water flows into the nozzle body 40 and is ejected from the ejection port 48.

  When the supply of cleaning water is stopped, the valve 45 closes the water supply port 44 by the urging force of the valve spring 46, and retreats so that the nozzle body 40 is accommodated in the nozzle holder 10 by the urging force of the return spring 42. .

  When the nozzle body 40 is made to protrude from the nozzle holder 10 and the nozzle body 40 is cleaned from the state in which the nozzle body 40 is retracted, the movable shaft 50 having the permanent magnet 51 is moved in a direction approaching the nozzle 2.
