  As a result, as shown in FIG. 8D, the second wire 46 is exposed from the upper end of the sheath tube 53 located in the rear upper opening 10a.

  Next, with reference to FIG. 9, the procedure for connecting the second wire 46 to the connector 50 in the rear upper opening 10a will be described.

  First, as shown in FIG. 9A, the sphere 46c attached to the tip of the second inner wire 46 exposed from the upper end of the sheath tube 53 and the second inner wire 46 continuing from the sphere 46c approach the front surface of the connector 50. Let

  Next, as shown in FIG. 9B, the sphere 46c is accommodated in the accommodating portion 68a from above the drop-off preventing wall 68b. Next, the second inner wire 46b is passed through the front slit 76 formed in the dropout prevention wall 68b. Here, in order to pass the second inner wire 46b through the front slit 76, by applying a force to the second inner wire 46b, the stopper 68c provided on the drop-off prevention wall 68b is elastically deformed outward, and the second The inner wire 46 b can enter the front slit 76. Then, the second inner wire 46b is moved through the front slit 76 formed in the drop-off preventing wall 68b to the slit 74 formed in the accommodating portion 68a. Thereby, the 2nd wire 46 and the connector 50 are connected. Thereafter, the back upper opening 10a and the back lower opening 10b are closed by a decorative cover (not shown), and the construction work is completed.

Next, the operation of the flush toilet apparatus 1 according to the embodiment of the present invention will be described.
As described above, since the flush toilet apparatus 1 according to the present embodiment performs jet water discharge using the pressurizing pump 36, it cannot perform normal toilet flushing during a power failure. For this reason, it is necessary to perform toilet cleaning using a power failure response function in the event of a power failure. When using the power failure response function, the user first removes the decorative cover (not shown) covering the rear upper opening 10a (see FIG. 3) at the rear of the flush toilet main body 2 and removes the first wire 44. To expose. Next, the user puts a finger on the grip 44c of the first wire 44 and pulls the first inner wire 44b.

When the first inner wire 44 b is pulled, the second inner wire 46 b and the third wire 52 are pulled through the connector 50.
When the second inner wire 46b is pulled, the slider 60 (see FIG. 7) fixed to the tip of the second inner wire 46b is inclined along the sliding groove 58 against the biasing force of the coil spring 62. Moved upwards. When the slider 60 is moved, the rotary shaft 42a is rotated via the arm 64, whereby the valve element 42 is moved from the “open position” (see FIG. 5) to the “closed position” (see FIG. 2). .

  When the third wire 52 is pulled out by a predetermined amount, the switch unit 48 sends a signal to the electromagnetic valve 28 (see FIG. 2) to open it. The electrical signal sent to the electromagnetic valve 28 and the electric power for opening the electromagnetic valve 28 are supplied by an emergency battery or a large-capacity capacitor (not shown) built in the function unit 8. When the solenoid valve 28 is opened, cleaning water is supplied by the water supply pressure, and this cleaning water flows from the rim spout 26 into the bowl portion 20. When the cleaning water flows in, the cleaning water in the bowl portion 20 flows into the descending conduit 22d over the bent portion 22c of the drain trap conduit 22. Here, since the valve body 42 provided in the drain socket 38 has been moved to the “closed position” by the user's operation, the wash water that has flowed into the descending pipe line 22d is almost downstream of the valve body 42. It does not flow and remains on the upstream side of the valve body 42.

  As a result, the inside of the drain trap pipe 22 is almost full, and the water level in the bowl portion 20 is also higher than the stored water level L defined by the bent portion 22c. When the water level in the bowl part 20 rises to a predetermined water level, the user loosens the force pulling the first inner wire 44b. When the user loosens the force, the second inner wire 46b, the first inner wire 44b, and the third wire 52 are moved toward the drain socket 38 by the biasing force of the coil spring 62 (FIG. 7) provided in the drain socket 38. Pulled back to. At the same time, the slider 60 is also moved obliquely downward along the sliding groove 58 by the biasing force of the coil spring 62. When the slider 60 is moved, the rotary shaft 42a is rotated via the arm 64, whereby the valve element 42 is moved from the “closed position” (see FIG. 2) to the “open position” (see FIG. 5). .

As a result, the cleaning water accumulated on the upstream side of the valve body 42 falls toward the drain pipe 40, and negative pressure is generated in the drain trap pipe 22 to activate the siphon action. Due to the occurrence of the siphon action, the cleaning water and dirt in the bowl portion 20 are sucked into the drain trap pipe 22 and discharged to the drain pipe 40. On the other hand, when the user loosens the pulling force of the first inner wire 44b and the gripping portion 44c (see FIGS. 3 and 4) returns to the original position, the switch unit 48 opens the solenoid valve 28 (see FIG. 2). After maintaining the state for a predetermined time, the electromagnetic valve 28 is closed. Thus, since a predetermined amount of washing water is supplied even after the siphon action occurs, the water level in the bowl portion 20 returns to the original stored water level L, and one toilet flushing is completed.
Further, since the switch unit 48 connected to the connector 50 is connected coaxially with this operation direction with respect to the operation of the grip portion 44c of the first wire 44 by the user, the switch unit 48 is overloaded. Can be prevented.

Next, the effect by the flush toilet apparatus 1 of this embodiment is demonstrated.

The electromagnetic valve (water supply device) 28 allows the cleaning water to flow into the bowl portion 20 in a state where the valve element 42 is moved to the “closed position”. Next, when a predetermined amount of washing water is accumulated in the bowl portion 20, the valve body 42 is moved to the “open position”, so that the accumulated water and filth in the bowl portion 20 are discharged via the drain trap pipe 22. It is discharged to the drain pipe 40. At this time, since the first wire 44 extending from the gripping portion 44c for transmitting a force based on the operation on the gripping portion 44c, the second wire 46 extending from the drain socket 38, and the switch unit 48 are connected by the connector 50, the gripping portion The force based on the operation on 44c is transmitted from the first wire 44 to the second wire 46 and the switch unit 48, whereby the valve body 42 can be easily opened and closed and the washing water from the electromagnetic valve 28 can be easily introduced. Furthermore, according to this embodiment, in the construction work when installing the flush toilet apparatus 1, the second wire 46 drawn to the back lower opening 10b by the sheath tube 53 is guided and pulled up to the back upper opening 10a.
