In this embodiment, the device case 50 has a substantially box-like shape that opens forward and upward, and its front edge is located in a substantially vertical plane (not shown) and has a substantially U-shape when viewed from the front. Yes. The device case 50 becomes the fixed member 5 to which the local cleaning device 4 (fluid ejection device) is fixed. The local cleaning device 4 includes a local cleaning nozzle 41, a driving unit (not shown) that drives the local cleaning nozzle 41, and a control unit that controls the driving unit. The local cleaning nozzle 41 serves as a fluid discharge portion that discharges fluid into the bowl portion 11. In the present embodiment, the local cleaning nozzle 41 is connected to a water source such as tap water and discharges water as a fluid. Examples of the local cleaning nozzle 41 include a buttocks cleaning nozzle and a bidet cleaning nozzle. In addition to the local cleaning nozzle 41, a nozzle cleaning nozzle that cleans the buttocks cleaning nozzle or the bidet cleaning nozzle may be provided as the fluid discharge unit.

  A motor that moves the local cleaning nozzle 41 back and forth may be provided as the driving means. Further, as a driving means, an electromagnetic valve for switching between communication and shielding with a water supply as a water source is provided, and the local cleaning nozzle 41 is advanced by water pressure by communicating with the water supply, or biasing means such as a spring is shielded from the water supply. Alternatively, the local cleaning nozzle 41 may be moved backward. The driving means may be other means and is not particularly limited.

  The control unit is composed of a microcomputer or the like, and controls driving means to switch between the advance and retreat of the local cleaning nozzle 41 and the discharge and stop of the fluid from the local cleaning nozzle 41. In addition, when a plurality of nozzles are provided as the local cleaning nozzle 41, a driving unit that can be driven for each nozzle is provided, and the control unit controls to drive an arbitrary nozzle.

  Of the local cleaning device 4 as described above, the local cleaning nozzle 41 is placed and fixed on the device case 50 at the front end of the rear part 3. The local cleaning nozzle 41 protrudes forward from the device case 50 by moving forward, and does not protrude from the device case 50 by moving backward. Note that it may slightly protrude from the device case 50 in the most retracted state.

  Moreover, in this embodiment, although not shown in figure, functional parts, such as a ventilation duct, a hot water storage tank, and a water supply pump, are installed behind the apparatus case 50. Further, a warm air fan for supplying warm air is installed on the side of the device case 50.

  The upper cover 31, the rear skirt, and the left and right side skirts 32 constituting the rear part 3 are formed of synthetic resin in this embodiment and are detachably combined. The upper cover 31, the rear skirt, and the left and right side skirts 32 may be omitted. Further, the upper cover 31, the rear skirt, the left and right side skirts 32, and the device case 50 may be formed of a material other than synthetic resin.

  As shown in FIG. 3 (b), the front part 1 is provided with a rising wall 22 positioned on the upper surface of the rear portion 21 of the rim 2 so as to go rearward. The rising wall 22 prevents water from entering the rear part 3 along the upper surface of the rim 2.

  Then, an opening 23 is formed in a portion facing the front bowl portion 11 of the rear portion 21 of the rim 2 so that the fluid discharge portion (local cleaning nozzle 41) protrudes into and out of the bowl portion 11. Is. Furthermore, in this embodiment, the opening part 24 from which the warm air is discharged is formed adjacent to the right and left of the opening part 23 of the rear part 21 of the rim 2, and the warm air is blown through the opening part 24 by the warm air fan. Can be discharged.

  In the toilet device, as shown in FIG. 1A, the front part 1 is in a state where the front part 42 (see FIG. 2) of the local cleaning device 4 is located below the rear part 21 of the rim 2. And the rear part 3 are connected. The rear part 3 is fixed to the support frame by a fixing tool (not shown) made of screws, but may be fixed to the support frame (not shown) by fitting. The front part 1 is mounted on the rear part 3 fixed to the support frame from the front, and the front part 1 is fixed by a fixing tool (not shown) made of screws.

  The device case 50 as the fixed member 5 is provided with a restricting portion in which the front portion 42 of the local cleaning device 4 is inserted from the rear side to restrict its movement. As shown in FIG. 2, the restricting portion includes a front restricting portion 53 that restricts the forward movement of the front portion 42, a lateral restricting portion 54 that restricts the lateral movement of the front portion 42, and a front portion. And an upper restricting portion 55 that restricts the upward movement of 42. The local cleaning device 4 is provided with a flat-plate-like insertion piece 44 that protrudes from the left and right sides of the front portion 42. Then, the front restricting portion 53 located on the front side of the fitting piece 44 restricts the forward movement of the fitting piece 44. Further, the lateral restriction portions 54 located on both the left and right sides of the insertion piece 44 restrict the movement of the insertion piece 44 to the left and right sides. Further, the upper restricting portion 55 located on the upper side of the insertion piece 44 restricts the upward movement of the insertion piece 44. Further, the downward movement of the front portion 42 of the local cleaning device 4 is restricted by the device case 50.

  In the present embodiment, the fitting piece 44 is formed with a fixing tool insertion hole 48 that is conventionally used, and can be fixed to the conventional toilet device.

  And as shown to Fig.1 (a), the fixing | fixed part 43 (refer FIG.1 (b)) to the to-be-fixed member 5 of the local cleaning apparatus 4 is rather than the rear part 21 (refer FIG.3 (b)) of a rim. It is located on the rear side. In the present embodiment, a fixing portion 43 having a vertically long rib shape is provided at the rear end of the local cleaning device 4, and a pressing member 7 that presses the fixing portion 43 is provided on the device case 50. The holding member 7 is formed by a mounted portion 71 attached to the device case 50 and an insertion groove forming portion 72 protruding forward from the mounted portion 71, and the insertion groove 73 is provided with the insertion groove 73. In the pressing member 7, a fixing tool 52 made of a screw or the like is inserted into a fixing hole (not shown) formed in the attached portion 71, and the fixing tool 52 is attached to the mounting portion 51 having a boss hole formed in the device case 50. Is fixed to the device case 50 by being screwed. The fixing portion 43 is pressed by the rear end portion of the insertion groove 73 of the pressing member 7 fixed to the device case 50, and movement of the local cleaning device 4 to the rear side is restricted. As described above, since the movement of the front part 42 of the local cleaning device 4 is restricted with respect to the fixed member 5, the position of the front part 42 of the local cleaning device 4 is shifted even if the local cleaning nozzle 41 protrudes and sinks. In this case, water and discharge from the local cleaning nozzle 41 are stabilized.

  In the toilet apparatus, the front part 42 of the local cleaning device 4 is located on the lower side of the rear part 21 of the rim 2 of the front part 1, and the fixed part 5 of the local cleaning device 4 is fixed to the fixed member 5. The fixing portion 43 is located on the rear side of the rear portion 21 of the rim 2 of the front part 1. For this reason, when the local washing | cleaning apparatus 4 is removed from the apparatus case 50, the front part 1 does not need to be removed and workability | operativity is good.

  In the present embodiment, a biasing portion 74 that biases the fixing portion 43 forward is provided at the rear end portion of the insertion groove 73. By providing the urging unit 74, it is possible to prevent the local cleaning device 4 from shifting backward.
