In such a water supply pipe (6), an electrically driven water supply valve (9) for controlling the water supply is provided in the middle of the pipe. Therefore, when the water supply valve (9) is opened, water is supplied from the water supply (8) to the water supply pipe (6) and the rim water passage connection part (5).
And via the rim (2), it is directly fed into the bowl (1).

On the other hand, the drain port (10) at the bottom of the bowl (1)
A drain pipe portion (11) extending toward the rear of the toilet is connected to the. A flapper valve (12) for opening and closing the terminal opening is provided in the terminal opening, and the flapper valve (12) is supported by a rotating shaft (13) so as to be rotatable and reversible around it. Rotation and reversal of the flapper valve (12) are realized by a mechanism part connected to the flapper valve (12) and equipped with a motor. Although not shown, the structure of this mechanism is not particularly limited, and any mechanism including conventionally known ones can be adopted.

The drain pipe portion (11) is also connected to a discharge pipe portion (14) extending in a direction perpendicular to the drain pipe portion (11), and the bottom end thereof is a discharge port (15). The drain pipe portion (11) and the discharge pipe portion (15) are also connected by an overflow pipe (16). The overflow pipe (16) once rises vertically from the drain pipe portion (11) and then bends downward to be discharged into the discharge pipe portion (1).
4), and the drain pipe part (11) and the discharge pipe part (15) are detoured and communicated with each other. Thus, the flush toilet is provided with a drainage passage extending from the bowl (1) to the discharge port (15).

Although not shown, the flush toilet has a control unit for controlling the operation of a motor provided in the mechanical unit of the water supply valve (9) and the flapper valve (12). The flush toilet is also provided with an operation system such as an operation panel.The operation system is electrically connected to the control unit so that a switch can be input from the operation system for the operation of the flush toilet. There is.

For example, in the flush toilet having the above-mentioned structure, as shown in FIG. 1, when the end opening of the drain pipe portion (11) is closed by the flapper valve (12),
Water is stored in the bowl (1) within the height of the overflow pipe (16) and sealed. The water level of this accumulated water can be adjusted by the amount of water supplied to the bowl (1). In this state, when toilet flushing is input, the control unit operates the motor and opens the water supply valve (9). This state is shown in the sectional view of FIG.

As shown in FIG. 2, at the time of cleaning, the flapper valve (12) is rotated upward by the operation of the motor to open the terminal opening of the drainage pipe (11). Then, the accumulated water in the bowl (1) is discharged from the drain port (10) via the drain pipe part (11) and the discharge pipe part (14) to the drain port (1).
It is discharged from 5) to the outside of the flush toilet. At the same time or before or after the water supply valve (9) is opened, water is supplied from the water supply (8) to the rim (2) through the water supply pipe (6) and the rim water supply connection (5).

Rinse more and wash the bowl surface. The water after cleaning goes through the drainage port (10) of the bowl (1) to the discharge port (15) like the accumulated water, and is discharged to the outside of the flush toilet bowl.

After this, when the cleaning stop is input, or after a predetermined time set in the control unit elapses, the control unit reverses the motor. As a result, the flapper valve (12) is reversed and the drain pipe section (11)
Close the end opening of the. In this state, the water supply valve (9) remains open and therefore the water supply (8)
Water continues to be supplied to the bowl (1), and water gradually accumulates in the bowl (1). Then, when the water level of the accumulated water reaches a predetermined level, the control unit closes the water supply valve (9). At this time, even if excess water may be supplied, since the overflow pipe (16) is provided in the drainage channel, excess water is removed from the overflow pipe (16).
Can be sent to the discharge pipe section (14), the accumulated water in the bowl (1) does not rise above a predetermined water level, and does not overflow from the bowl (1).

In the flush toilet as described above, a water level sensor is provided at a portion of the bowl (1) where the water level can be measured in the drainage path from the bowl (1) to the discharge port (15). The water level sensor may be at a predetermined position, for example in the bowl (1), or as shown in FIG.
7) can be installed at a predetermined position of the overflow pipe (16). The water level sensor (17)
By electrically connecting to the control unit, a water level detection signal can be output to the control unit.

On the other hand, the controller can be set to control the operation of the motor and the water supply valve (9) in response to the input water level detection signal. Specifically, when an increase in the water level in the bowl (1) is detected by the water level sensor, the control unit operates the motor and opens the water supply valve (9) as in the above-described cleaning. . By doing so, automatic cleaning can be realized during men's small use.

That is, the bowl (1) is used for men's small use.
Since the water level inside rises, this rise in water level is detected by the water level sensor. The control unit can control the operation of the motor and the water supply valve (9) in response to the water level detection signal input from the water level sensor. Therefore, when the water level rise due to men's small use is detected, the control shown in FIG. As described above, the flapper valve (12) is opened, so that the urine discharged into the bowl (1) can be discharged together with the accumulated water, and the wash water can be supplied into the bowl (1) from the rim portion (2). In this way, it becomes possible to realize automatic cleaning for men's small use, which was not possible with the conventional seating switch system. The function of the flush toilet is improved and the convenience is increased.

The operation after opening the flapper valve (12) and the water supply valve (9) can be performed as described above. Further, in this case, since the rise of the water level in the bowl (1) is detected by the water level sensor and the operation is performed based on this detection signal, the same operation can be performed not only for the men's small use but also for the heavy use. Become. At the time of urination, the water level in the bowl (1) rises for both small and large use.

Further, in the flush toilet shown in FIG. 1, it is possible to set the men's small use mode in the control section. In this men's small-use mode, the control unit operates the motor to keep the flapper valve (12) in the open state, and at the same time, opens the water supply valve (9). By doing this, not only is it possible to perform automatic cleaning for men's small use,
Bowl (1) when the men's pursuit mode is selected
Since the accumulated water inside is drained, splash water is prevented during men's small use. Further, since the flush water is supplied into the bowl (1) by opening the water supply valve (9), the generation of unpleasant noise during men's small use is eliminated.

Selection of such a men's small-use mode can be made by a switch input from an operation system such as an operation panel. In addition, to release the men's small-use mode, it can be forcedly released by a switch input, or the men's small-use mode can be set to continue within a predetermined time and be automatically released after that time. it can. There is no particular limitation on the method. When the men's small-use mode is released, the control unit reverses the motor, which causes the flapper valve (12) to reverse and closes the terminal opening of the drain pipe unit (11). After this, the water supply valve (9) is closed, and accumulated water of a predetermined water level is formed in the bowl (1) to seal the water.

Of course, the present invention is not limited to the above examples. It goes without saying that various aspects are possible in details such as the configuration and structure of the mechanism section and the control section of the flush toilet.
