  Moreover, in 1st embodiment, functional components (not shown), such as a ventilation duct, a hot water storage tank, a pump for water supply, and a warm air fan, are installed in the back and the side of the apparatus case 50.

  As shown in FIG. 1 (a), the bowl unit 1 is provided with a rising wall 21 that is located on the upper surface in front of the rear end of the rear portion of the rim 2 and that is located upward as it goes rearward. In the first embodiment, the rising wall 21 is inclined so as to be positioned upward as it goes backward in the substantially half portion on the base end portion side that protrudes from the rear portion of the rim 2, and the substantially half portion on the tip end portion side. Is standing up substantially upward. The rising wall 21 prevents water from entering the fluid discharge device unit 3 along the upper surface of the rim 2.

  An opening 22 is formed in one or both of the rising wall 21 and the rear end portion of the rim 2 so that the fluid discharge portion 15 is inserted into the bowl portion 11. In the first embodiment, an opening 22 is formed from the lower end of the rising wall 21 to the rear end of the rim 2.

  Furthermore, a waterproof wall surrounding the opening 22 is provided on the upper surface of the rear end portion of the rim 2. In the first embodiment, ribs 23 are formed on both the left and right sides of the opening 22 from the lower surface of the rising wall 21 to the upper surface of the rear end of the rim 2 as the waterproof wall, and the left and right A connecting rib 24 that connects the ribs 23 is formed. The waterproof wall of the first embodiment is composed of left and right ribs 23 and connecting ribs 24, and has the same U shape as the front end of the device case 50, and the rear end edge is located in a substantially vertical plane. ing. In the apparatus case 50, the fluid discharge portion 15 is placed on the upper surface thereof, and the nozzle receiving portion 5 is placed on the upper surface of the periphery of the opening 22 at the rear portion of the rim 2 via the packing 13. In the first embodiment, as shown in FIG. 1A and FIG. 4, the nozzle receiving portion 5 is placed on the upper surface of the periphery of the opening 22 at the rear portion of the rim 2 through the packing 13. A placement portion 4 is formed.

  In the first embodiment, the packing 13 is fixed to the lower surface of the nozzle receiving portion 5, but the packing 13 may be fixed to the placement portion 4 or may not be fixed to either. The packing 13 prevents water that has entered the opening 22 from the bowl portion 11 from entering the inside (inside the device case 50) between the lower surface 5a and the upper surface.

  However, if the relative positional relationship between the bowl unit 1 and the fluid discharge device unit 3 deviates from a predetermined positional relationship, the water stopping performance of the packing 13 interposed between the placement portion 4 and the nozzle receiving portion 5 is not stable. . Therefore, the bowl unit 1 and the fluid discharge device unit 3 are provided with positioning parts 61 to 66 and 71 to 76 for positioning the placement part 4 and the nozzle receiving part 5 at predetermined positions.

  The positioning units include height positioning units 61 to 64 provided in the bowl unit 1, left and right positioning units 65 to 66, height positioning units 71 to 74 provided to the fluid ejection device unit 3, and left and right positioning units 75 to 76. It consists of.

  In the first embodiment, as shown in FIG. 1A, the height positioning portions 61 to 64 are formed as protrusions that protrude rearward from the back surface of the rising wall 21. Moreover, the left-right positioning parts 65-66 protrude back from the back surface of the rising wall 21, and in the first embodiment, the ribs 23 form a waterproof wall.

  In the first embodiment, as shown in FIGS. 1B and 6, the height positioning portions 71 to 74 are formed as protrusions protruding upward from the device case 50. Further, the left and right positioning portions 75 to 76 are formed of concave grooves that open forward and are recessed backward.

  In order to connect the fluid discharge device unit 3 to the bowl unit 1, first, the fluid discharge device unit 3 is brought closer to the bowl unit 1 from the rear. And the nozzle receiving part 5 is mounted in the mounting part 4 from back, and the nozzle receiving part 5 is moved ahead. At this time, the height positioning parts 71 to 74 enter below the height positioning parts 61 to 64, and the upward movement of the fluid discharge device unit 3 with respect to the bowl unit 1 is restricted. In 1st embodiment, the inclination which is located below so that it goes to the upper end part of the height positioning parts 71-74 is formed, and height positioning is carried out under the height positioning parts 61-64. The parts 71 to 74 are easy to enter. Thereby, the apparatus case 50 will be in the state clamped by the mounting part 4 and the height positioning parts 61-64 of the bowl part unit 1 from the upper and lower sides, and an up-and-down positioning will be made. At this time, since the upper end portions of the height positioning portions 71 to 74 are inclined, the height positioning portions 71 to 74 enter even if there is a manufacturing error in the bowl unit 1 or the fluid ejection device unit 3. At this time, the height positioning parts 61 to 64 come into contact with any part of the inclination. Thereby, the apparatus case 50 is reliably clamped from the upper and lower sides by the placement part 4 and the height positioning parts 61 to 64 of the bowl part unit 1.

  As for the left and right positioning, when the nozzle receiving portion 5 is moved forward, the left and right positioning portions 65 to 66 enter the recessed grooves of the left and right positioning portions 75 to 76, and the fluid discharge device unit 3 with respect to the bowl unit 1 Movement in the left-right direction is restricted. Thereby, the bowl part unit 1 and the fluid discharge apparatus unit 3 are positioned right and left.

  The bowl unit 1 and the fluid discharge device unit 3 are connected by screws (not shown) and other various connecting means. Due to the coupling by the coupling means, the upper surface of the coupling rib 24 and the lower surface of the nozzle receiving portion 5 are pressed against each other via the packing 13. Thereby, packing 13 is fully compressed and the water stop effect is secured.

  In the present invention, the relative positional relationship between the bowl unit 1 and the fluid discharge device unit 3 is prevented from deviating from a predetermined positional relationship, and the water stop performance is stabilized. Further, the positioning portions 61 to 66 are provided on the rising wall 21 directly connected to the rim 2, so that the rigidity is improved and the bending of the positioning portions 61 to 66 is suppressed, and the water stop performance is prevented from being lowered due to the bending. The

  Further, the positioning portions 61 to 66 and 71 to 76 for positioning are provided in the vicinity of the placement portion 4 and the nozzle receiving portion 5, thereby suppressing the deviation between the placement portion 4 and the nozzle receiving portion 5. Further reduction in water stoppage performance can be achieved.
