Description

The present invention relates to a flush toilet, and more particularly to a flush toilet device having a power failure response function.

Conventionally, flush toilets of the type in which rim water discharge and Zet water discharge are electrically controlled by a controller and flush toilets of the type in which the wash water is pressurized by a pump to perform rim water discharge and Zet water discharge are flushed in the event of a power failure. There is a problem that it cannot be executed, and a flush toilet equipped with a power failure response function is required.

In the flush toilet described in Patent Document 1, the drainage socket is provided with an on-off valve for opening and closing the flow path, and this on-off valve is moved to the closed position by pulling the inner wire extending from the drainage socket. It is configured as follows. In the event of a power failure, the user first supplies wash water to the bowl portion of the flush toilet with the on-off valve closed by pulling the inner wire. By supplying the washing water to the bowl portion in the state where the flow path of the drainage socket is closed, the water level of the accumulated water in the bowl portion rises and the drain trap pipeline extending from the bowl portion is filled with water. If the user relaxes the force to pull the inner wire in this state, the on-off valve of the drainage socket is opened, and a siphon phenomenon occurs in the drainage trap pipeline. As a result, the filth and the washing water in the bowl portion are sucked into the drain trap pipeline and discharged to the drain pipe.

Further, in this flush toilet, the grip portion for the user to pull the inner wire is housed inside the skirt portion on the rear side of the flush toilet. In the event of a power outage, the user can open and close the on-off valve by removing the decorative cover that forms the skirt of the flush toilet, taking out the grip that is stored inside, and pulling it.

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 me.

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

Next, the operation of the flush toilet device 1 according to the embodiment of the present invention will be described.
As described above, since the flush toilet device 1 according to the present embodiment uses the pressurizing pump 36 to discharge water from the flush toilet, it is not possible to perform normal flush toilet cleaning in the event of a power failure. Therefore, in the event of a power failure, it is necessary to use the power failure response function to clean the toilet bowl. 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 body 2 and removes the first wire 44. To expose. Next, the user hooks a finger on the grip portion 44c of the first wire 44 and pulls the first inner wire 44b.

When the first inner wire 44b is pulled, the second inner wire 46b and the third wire 52 are pulled via 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 obliquely along the sliding groove 58 against the urging force of the coil spring 62. Moved upwards. When the slider 60 is moved, the rotation shaft 42a is rotated via the arm 64, whereby the valve body 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 solenoid valve 28 (see FIG. 2) to open the solenoid valve 28. The electric signal sent to the solenoid valve 28 and the power for opening the solenoid valve 28 are supplied by an emergency battery or a large-capacity capacitor (not shown) built in the functional unit 8. When the solenoid valve 28 is opened, wash water is supplied by the water supply pressure of tap water, and the wash water flows into the bowl portion 20 from the rim spout 26. When the wash water flows in, the wash water in the bowl portion 20 passes through the bent portion 22c of the drain trap pipeline 22 and flows into the descending pipeline 22d. Here, since the valve body 42 provided in the drainage socket 38 has been moved to the “closed position” by the operation of the user, the washing water flowing into the descending pipe line 22d is almost discharged to the downstream side of the valve body 42. It does not flow and stays on the upstream side of the valve body 42.

As a result, the drain trap pipeline 22 is almost filled with water, and the water level in the bowl portion 20 is also higher than the pooled water level L defined by the bent portion 22c. When the water level in the bowl portion 20 rises to a predetermined water level, the user relaxes the force for pulling the first inner wire 44b. When the user relaxes the force, the second inner wire 46b, the first inner wire 44b, and the third wire 52 move toward the drainage socket 38 due to the urging force of the coil spring 62 (FIG. 7) provided in the drainage socket 38. Pulled back to. At the same time, the slider 60 is also moved diagonally downward along the sliding groove 58 by the urging force of the coil spring 62. When the slider 60 is moved, the rotation shaft 42a is rotated via the arm 64, whereby the valve body 42 is moved from the “closed position” (see FIG. 2) to the “open position” (see FIG. 5). ..

As a result, the washing water accumulated on the upstream side of the valve body 42 falls toward the drainage pipe 40, a negative pressure is generated in the drainage trap pipe line 22, and the siphon action is activated. Due to the occurrence of the siphon action, the washing water and filth in the bowl portion 20 are sucked into the drain trap pipeline 22 and discharged to the drain pipe 40. On the other hand, when the user relaxes the force for pulling the first inner wire 44b and the grip 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 solenoid valve 28 is closed. As a result, 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 pooled water level L, and one toilet bowl washing is completed.
Further, since the switch unit 48 connected to the connector 50 is connected coaxially with the operation direction of the grip portion 44c of the first wire 44 by the user, the switch unit 48 is overloaded. Can be prevented.
