And the 2nd plate 2 and the 3rd plate 3 are being fixed in the state which the nail | claw part of the hook 570 and the engaging groove were mutually engaged.

  Therefore, for example, even if the user tries to lift the front side of the casing 200 forcibly or mischievously, the elevating device having the hook 570 is engaged with the claw portion and the engagement groove. 500 cannot rise from this state. That is, the 3rd plate 3 to which the raising / lowering apparatus 500 was attached cannot raise from the state currently fixed with the 2nd plate 2, as represented to FIG.

  Thereby, even if a user tries to lift or raise the front side of the casing 200 forcibly or mischievously, the casing 200 cannot rise from the state. Therefore, it can suppress that the raising / lowering apparatus 500 etc. of the toilet apparatus concerning this embodiment are destroyed or damaged.

  On the other hand, even if the user rotates the handle 540 and tries to raise the front side of the front base plate 10, the front side of the front base plate 10 cannot rise if the claw portion and the engagement groove remain engaged. Therefore, in the toilet apparatus according to the present embodiment, when the user pulls out the handle 540 as indicated by the arrow A <b> 1 illustrated in FIG. 2, the claw portion of the hook 570 can be retracted into the case 510 of the lifting device 500. Thereby, the engagement between the claw portion and the engagement groove is released, and the front side of the front base plate 10 can be lifted away from the upper surface 820 of the toilet bowl 800.

  In this state, when the user rotates the handle 540 as indicated by an arrow A2 shown in FIG. 2, the support column 550 receives the rotational force transmitted from the handle 540 via the rotation shaft 530, and rotates. Move. That is, when the user rotates the handle 540, the support column 550 is inverted as viewed from the lower surface of the third plate 3.

  Then, the support column 550 is supported by the third plate 3 as illustrated in FIG. As a result, the column 550 has the first plate 1 fixed to the third plate 3 to which the lifting device 500 is attached, that is, the front side of the front base plate 10 as a fulcrum with the rotation shaft 4 of the third plate as a fulcrum. It can be raised from the upper surface 820 of the toilet bowl 800 and can be separated and inclined. When the support column 550 rotates, the end portion of the support column 550 that is not fixed to the rotation shaft 530 slides on the surface of the third plate 3 while contacting the surface of the third plate 3.

  According to this, the user can easily rotate the handle 540 with a smaller force, and lift the front side of the front base casing 200 away from the upper surface 820 of the toilet bowl 800. Further, according to this, the front side of the front base plate 10 rises from the upper surface of the toilet main body, so that the front base plate 10, the local cleaning mechanism mounted on the front base plate, and the casing 200 can be inclined. It can be easily raised without using a large-scale device that requires durability and great force. Therefore, it is possible to easily clean dirt and dust collected in the gap between the casing 200 and the toilet bowl 800.

  Further, since the third plate and the first plate are tilted and lifted with the pivot axis of the third plate 3 as a fulcrum, the front base plate 10, the local cleaning mechanism, The casing 200 can be inclined.

  Next, a water supply structure for the toilet cleaning mechanism and the local cleaning mechanism will be described. FIG. 9 is a perspective view of the toilet device according to the present embodiment with the casing removed, FIG. 10 is a perspective view of the toilet device according to the present embodiment with the casing removed, and FIG. FIG. 12 is a partially cutaway cross-sectional view showing the storage state of the water supply pipe of the embodiment, and FIG. 12 is a side view showing the state of the water supply pipe when the front base plate is inclined in the present embodiment. In these drawings, the front base plate 10 is shown in a state where the first plate on which the main part of the local cleaning mechanism is mounted is omitted.

  As shown in FIG.9 and FIG.10, the water supply main pipe 60 is connected to the left side behind the toilet bowl 800, and water can be supplied from a water supply source. The water supplied from the main water supply pipe 60 is supplied to the local cleaning electromagnetic valve 14 arranged at the tip of the third plate 3 by the first water supply pipe arranged in the front-rear direction on the upper surface of the third plate 3. In addition, the tank electromagnetic valve 24 can be supplied with water by a second water supply pipe arranged so as to rise obliquely from the rear to the front along the side surface of the tank 22.

  The water supplied toward the local cleaning electromagnetic valve 14 by the first water supply pipe 70 is heated to hot water by the heating means when the local cleaning electromagnetic valve 14 is opened based on an operation command of a local cleaning mechanism (not shown). Water can be discharged from the nozzle toward the local part of the human body. In addition, when the water supplied to the tank solenoid valve by the second water supply pipe 80 is discharged from the cleaning water stored in the tank 22 for cleaning the toilet 800, the water level in the tank 22 decreases. By detecting a drop in the water level with a float switch (not shown) and opening the tank electromagnetic valve 24, water can be supplied toward the tank 22. Thus, when the local cleaning electromagnetic valve 14 and the tank electromagnetic valve 24 are closed, the first water supply pipe 70 and the second water supply pipe 80 are constantly supplied with the water supply pressure from the water supply source. For the first water supply pipe 70 and the second water supply pipe 80, a metal non-flexible pipe excellent in pressure resistance is used. Of course, a plurality of tubes can be connected by a joint.

  A configuration for branching the water supply from the water supply main pipe 60 into the first water supply pipe 70 and the second water supply pipe 80 will be described with reference to FIG. The water supply main pipe 60 and the first water supply pipe 70 are connected by a retaining ring (not shown). The water supplied from the water supply source through the water supply main 60 is supplied to the first water supply pipe 70. In the first water supply pipe 70, a water supply pipe rotation shaft 72 and a branch connection portion 74 are formed on the same axis so as to be orthogonal to the water flow of the first water supply pipe. One end of the second water supply pipe 80 is inserted into and connected to the branch connection portion 74. One end side of the second water supply pipe 80 has an elbow shape, and a water supply pipe rotation shaft 82 is formed coaxially with one end inserted into the branch connection portion 74.

  The first water supply pipe 70 and the second water supply pipe 80 are connected so as to be rotatable around a second rotation axis that is an axis of the branch connection portion 74. Specifically, the connection state at the branch connection portion 74 is maintained by fitting and fixing the water supply pipe rotation shafts 72 and 82 to the pair of water supply bearing portions 50 formed on the third plate. Thus, the first water supply pipe 72 is rotatable with respect to the second water supply pipe 80 while suppressing the occurrence of water leakage.

  Further, when the rotation shaft 4 formed on the third plate 3 is fitted into the rotation bearing portion 5 of the rear base plate 20, a first rotation shaft is formed for rotating the front of the front base plate 10 when it is raised. ing. The first water supply pipe 70 and the second water supply are arranged on the same axis line as the second rotation shaft that is the axis of the branch connection portion 74 with respect to the first rotation shaft. The front base plate can be raised without disconnecting from the tube 80.

  A state where the front side of the third plate 3 which is a part of the front base plate 10 is raised will be described with reference to FIG. 11 is fixed along the upper surface of the third plate 3 in the process in which the front side of the third plate 3 rises with the first rotation shaft, which is the shaft center of the rotation shaft 4 shown in FIG. About the 1st water supply pipe 70, the front side raises by rotating centering on the 2nd rotating shaft which is an axis of the branch connection part 74. As shown in FIG. As a result, as shown in FIG. 12, on the day, the first water supply pipe 70 is inclined so as to rise toward the front side (the right side in FIG. 12).

  On the other hand, the second water supply pipe 80 is connected to the tank solenoid valve 24 of the tank 22 fixed to the toilet bowl 800 so that the downstream side does not move even when the third plate 3 rotates. The upstream side of the second water supply pipe does not rotate even when the first water supply pipe 70 rotates at the branch connection portion 74, and the second water supply pipe 80 is located behind the tank as shown in FIG. 12. The posture of standing up diagonally upward from the front is not changed. Note that the second water supply pipe 80 has an elevation angle rising from the second rotation shaft, which is the axis of the branch connection portion 74, toward the tank solenoid valve 24. Therefore, there is a space between the second water supply pipe and the third plate 3 even during the upward rotation of the third plate 3, which interferes with the upward rotation of the third plate 3. Thus, the upward rotation is not hindered.
