This trap structure itself is well known.

  The end of the water supply pipe protrudes from the wall surface of the toilet room, and a stop cock 10 is attached to the end of the water supply pipe. This stop cock 10 is connected to a strainer 12 installed at the rear part of the Western-style toilet 1 via a water supply hose 11. The water that has passed through the strainer 12 can be supplied to the valve devices 22 and 23 of the electric valve unit 20.

  The electric valve unit 20 drives the valve devices 22 and 23 arranged therein by the motor 21 to supply water to the rim nozzle water supply pipe 24 or the jet nozzle water supply pipe 25.

  Note that a manual washing handle 28 is attached to the rotating shaft of the motor 21 so that the toilet can be used even during a power failure.

  The electric valve unit 20 is provided with vacuum breakers 26 and 27 for breaking the negative pressure in the rim nozzle water supply pipe 24 and the jet nozzle water supply pipe 25. The vacuum breakers 26 and 27 are configured to open when negative pressure is generated in the water supply pipe 24 or 25 and to communicate the inside of the water supply pipe 24 or 25 with the atmosphere.

  A toilet seat box 30 is installed on the rear upper surface of the Western-style toilet 1. The toilet seat 31 and the toilet lid 32 are supported with respect to the toilet seat box 30 so that they can be turned upside down. A toilet lid / toilet seat rotation device 33 having a motor for rotating the toilet seat 31 and the toilet lid 32 is installed in the toilet seat box 30. On the front surface of the toilet seat box 30, a human body detection sensor (hereinafter also referred to as a human body sensor) 34 for detecting a human body sitting on the toilet seat 31 is provided as a seating detection means. The human body sensor 34 has a detection area set so that the human body in the toilet lid rotation area on the upper side of the toilet bowl 2 can also be detected.

In addition to the detection signal of the human body sensor 34, the controller 40 receives signals from a mode selection switch 41, a washing switch (flash switch) 42 and a toilet lid / toilet seat opening / closing switch 43 provided on the remote controller. The electric valve unit 20 and the toilet lid / toilet seat rotation device 33 are controlled based on the signal.

  The mode selection switch 41 is a switch for switching between the cover cleaning mode and the normal cleaning mode. The toilet lid / toilet seat rotation switch 43 is a switch for selecting three patterns of opening both the toilet lid 32 and the toilet seat 31, opening only the toilet lid 32, and closing both the toilet lid 32 and the toilet seat 31.

  Hereinafter, the operation of the toilet bowl cleaning device will be described. Hereinafter, the valve devices 22 and 23 may be simply referred to as valves 22 and 23.

  The toilet bowl cleaning pattern will be described with reference to FIG.

  First, a pattern when the normal cleaning mode similar to the conventional one is selected will be described with reference to FIG. 4 (a).

  When the washing switch 42 is operated to wash the Western-style toilet 1 after the stool (stool), first, the rim water supply valve 22 is opened for a predetermined time, and the washing water is supplied to the rim 3 by the tap water pressure. The adhered dirt is washed off to the trap part (rim cleaning process). At this time, the washing water flows down into the bowl while swirling along the bowl surface, and a swirling flow is formed in the toilet bowl 2.

  When a specified time has elapsed since the start of water supply to the rim 3, the rim water supply valve 22 is closed. After the valve 22 is closed or substantially simultaneously with the valve closing, the jet water supply valve 23 is opened for a predetermined time, water is ejected from the jet nozzle 5, siphon is induced in the trap portion, and sewage flows into the drain pipe. It is discharged (siphon cleaning process). Thereafter, the valve 23 is closed, the rim water supply valve 22 is opened again for a predetermined time, and trap water is stored.

  In this series of washing steps, the toilet lid 32 is in a state selected by the toilet lid / toilet seat opening / closing switch 43 and remains open or closed.

  Next, an operation pattern when the cover cleaning mode is selected will be described.

  When the human body detection sensor 34 detects a human body when the washing switch 42 is pressed, toilet flushing is performed according to the pattern as in the normal washing mode of FIG. 4 (a). In this case, of course, the toilet lid 32 is open.

  When the human body detection sensor 34 does not detect a human body when the cleaning switch 42 is pressed, an operation according to FIG. 4B is executed. That is, first, the rim water supply valve 22 is opened for a predetermined time, cleaning water is supplied to the rim 3 by tap water pressure, and the dirt adhering to the bowl surface is washed off to the trap portion.

  When a predetermined time t (for example, 2 to 4 seconds) elapses from the start of water supply to the rim 3, the toilet lid / toilet seat rotation device 33 starts to close the toilet lid 32 and before the rim water supply valve 22 is closed, the toilet lid 32 becomes a fully closed state. Thereafter, the valve 22 is closed. After the valve 22 is closed or substantially simultaneously with the valve closing, the jet water supply valve 23 is opened for a predetermined time, water is ejected from the jet nozzle 5, siphon is induced in the trap portion, and sewage flows into the drain pipe. It is discharged (siphon cleaning process). Thereafter, the valve 23 is closed, the rim water supply valve 22 is opened again for a predetermined time, and trap water is stored.

  In this way, when the user presses the toilet flushing switch 42 in a standing state, the toilet lid 32 is opened at the initial stage of the rim washing process, so it is possible to visually observe whether the toilet flushing is performed without any abnormality. . Thereafter, after the toilet lid 32 is closed, the jet washing process starts. In this jet washing process, the siphon is broken and air is sucked into the trap 6 from the toilet bowl 2 and a relatively loud sound such as go or gobogobo is generated, but since the toilet lid 32 is closed, this sound is Propagation to the surroundings is prevented (including suppression).

  In this embodiment, a swirl flow is formed in the toilet bowl 2 during rim cleaning. In this swirl flow, the water gently flows along the bowl surface, so that the cleaning sound is extremely small. Therefore, even if the toilet lid 32 is open, the sound transmitted to the surroundings is small.

[Another embodiment]
The above embodiment employs the jet nozzle 5 as the siphon inducing means, but FIG. 5 shows an embodiment in which the siphon is induced by applying a negative pressure to the trap secondary side instead of the jet nozzle 5. Is shown. In addition, in this invention, the trap secondary side shows the zone of the downstream side rather than the raising part 6a connected to the toilet bowl 2. FIG.

  In the embodiment of FIG. 5, a first trap 6 is provided in the lower part of the toilet bowl 2 of the toilet 1A. The standing part 6 b of the first trap 6 communicates with the second trap 60. The second trap 60 is formed of a U-shaped flow path that wraps around the lower side of the lowest part 61 at the lower part of the pipe wall of the standing part 6b and then reaches the drain pipe 8 through the highest part 62 for overflow. The height W of the highest portion 62 of the second trap 60 is slightly higher than the lowest portion 61.

  A negative pressure applying device is connected to the upper portion of the first trap 6 via a pipe 50 so that air is sucked and discharged from a space above the highest portion 6 c in the first trap 6.

  This negative pressure applying device has a tank 51 whose interior is divided into a lower chamber and an upper chamber by a diaphragm 51a, and a pump 53 connected to the upper chamber of the tank 51 via a pipe 52. The pipe 50 is connected to the lower chamber of the tank 51. The pump 53 is controlled by the controller 40.

  The pump 53 is of a piston / cylinder type, and operates to suck air from the upper chamber of the tank 51 or to return air to the upper chamber by stroking the piston. When air is sucked from the upper chamber by the pump 53, the diaphragm 51 a is lifted, and air is sucked and discharged from the upper part of the first trap 6 into the lower chamber of the tank 51.

  As described above, the height W of the highest position 62 of the second trap 60 is higher than the lowest position 61. Therefore, if water is present in the second trap 60 even at the W level, the lowest-order part 61 is submerged in the level W sealed water. For this reason, in this state, the standing part 6 b is a sealed space that is blocked from the atmosphere by the sealed water of the first trap 6 and the sealed water of the second trap 60.

  When air trapped in the first trap 6 is sucked out into the tank 51 in a state where the traps 6 and 60 are sealed with the sealing water in this way, the space above the highest portion 6c is included. The inside of the first trap 6 is almost full. And this siphon is formed in the 1st trap 6 when this water flows down the standing part 6b.

  When water supply to the rim 3 is started during toilet cleaning, the water in the first trap 6 overflows the highest level portion 6c and flows down into the second trap 60, so that the second trap 60 reaches the W level. There will be water.

  In this embodiment, wash water can be supplied to the rim nozzle 4 via a water electromagnetic valve 45, and this water electromagnetic valve 45 is controlled by a controller 40 (not shown in FIG. 5). Other configurations are the same as those in the above embodiment except that the motor-operated valve unit 20 is omitted and the jet nozzle 5 is omitted as described above.

  With reference to FIG. 6, the cleaning pattern in the cover cleaning mode of the toilet of FIG. 5 will be described.

  When the washing switch 42 is operated to wash the Western-style toilet 1 after the stool (stool), first, the water electromagnetic valve 45 for rim water supply is opened for a predetermined time, and the washing water is supplied to the rim 3 by tap water pressure. The dirt adhering to the surface is washed off to the trap part (rim cleaning process). At this time, the washing water flows down into the bowl while swirling along the bowl surface, and a swirling flow is formed in the toilet bowl 2.

  When a predetermined time (for example, 2 to 4 seconds) elapses from the start of water supply to the rim 3, the toilet lid / toilet seat rotation device 33 starts to close the toilet lid 32, and the toilet lid 32 is fully closed before the pump 53 is started. . Thereafter, the pump 53 is started, and then the water electromagnetic valve 45 is closed. When the pump 53 is activated, a negative pressure acts on the secondary side of the first trap 6 from the tank 51, the water in the ascending portion 6 a is pulled upward, a siphon is induced in the trap portion, and the sewage flows into the drain pipe 8. It is discharged (siphon cleaning process).

  During the siphon cleaning, the water electromagnetic valve 45 for rim water supply is closed, and then the pump 53 is stopped. Thereby, the siphon discharge flow is stopped. Since the inside of the first trap 6 was almost full while the siphon was formed, part of the water in the first trap 6 returns to the ascending portion 6a side when the siphon is stopped. Even if the water electromagnetic valve 45 is closed, the remaining water in the water channel downstream of the water electromagnetic valve 45 is continuously supplied into the toilet bowl 2. With these waters, accumulated water is formed at the bottom of the toilet bowl 2.

  As described above, also in the toilet apparatus of FIG. 6, when the cover cleaning mode is selected, the toilet lid / toilet seat rotating device 33 is operated by the toilet lid / toilet seat rotating device 33 after a predetermined time (for example, 2 to 4 seconds) has elapsed since the start of water supply to the rim 3. The lid 32 starts to close and the toilet lid 32 is fully closed before the pump 53 is started. Thereafter, the air in the first trap 6 is sucked into the tank 51, siphon is induced in the first trap 6, and sewage is discharged to the drain pipe (siphon cleaning step).

  For this reason, when the toilet cleaning switch 42 is pressed while the user is standing up, since the toilet lid 32 is opened at the initial stage of the rim cleaning process, it is possible to visually observe whether toilet cleaning is performed without any abnormality. Thereafter, after the toilet lid 32 is closed, the siphon washing process is started by being attracted by the negative pressure from the tank 51. Since the toilet lid 32 is closed in the siphon washing process, even a relatively loud washing sound is prevented from being transmitted to the surroundings.

  In this embodiment as well, a swirling flow is formed in the toilet bowl 2 at the time of rim cleaning, and the cleaning is performed gently. Also in this embodiment, when the normal washing mode is selected, in the above washing process, the toilet lid 32 remains open as selected by the toilet lid / toilet seat opening / closing switch 43. Or it remains closed.

[Duration of cleaning process]
The time from when the standing toilet lid 32 starts to close to when it is fully closed (inverted) is usually about 5 to 8 seconds. Thus, since it takes time to close the toilet lid 32, in the cover lid cleaning mode of FIG. 4 (b) and FIG. 6, the duration of the rim cleaning process is set to the closing time and the cleaning switch is pressed. Longer than the total time until the start of closing, and the toilet lid 32 is fully closed before jet water jetting or before the pump 53 of the negative pressure applying device is started, so that the stool can be surely received before the siphon washing process starts. The lid 32 is fully closed.

  In the case of FIG. 4, the jet water ejection duration is preferably about 3 to 5 seconds.

  In the case of FIG. 6, the operation duration of the pump 53 is preferably about 10 to 12 seconds. Further, the time from when the pump 53 is activated until the water electromagnetic valve 45 is closed is preferably about 3 to 5 seconds.

[Toilet device of claim 2]

  The rest of the structure of the toilet device of claim 4 and the cleaning pattern in each cleaning mode are the same as those of the toilet device of claim 2 described above.

  In the toilet apparatus according to claim 4, not only when the user sits on the toilet seat 31 and adds a use, but also when the user stands for the front of the toilet 1 and uses the boy for small use. A cleaning mode can be performed.

  That is, when a user stands in front of the toilet 1 during boy's small use, the human body sensor as the human body detecting means detects the user, and when the user leaves the toilet 1 after the toilet, the human body detecting means The human body sensor is not detected, and after a predetermined time has elapsed, the valve device 22 for rim water supply or the water electromagnetic valve 45 is automatically opened for a predetermined time, and cleaning water is supplied to the rim 3 and adheres to the bowl surface. Dirt is washed off to the trap part (rim cleaning process). When a predetermined time (for example, 2 to 4 seconds) elapses from the start of water supply to the rim 3, the toilet lid / toilet seat rotating device 33 starts to close the toilet lid 32. Thereafter, after the toilet lid 32 is fully closed, the jet cleaning process or the siphon cleaning process is started.

  Thus, in the toilet apparatus according to claim 4, even when boys are small, the user leaves the toilet 1 after the stool and the rim water supply valve device 22 or the water electromagnetic valve 45 is automatically activated. Since the toilet lid 32 is open at the initial stage when the rim cleaning process is started after the valve is opened, it is possible to visually observe whether toilet cleaning is performed without abnormality. Thereafter, after the toilet lid 32 is closed, the jet cleaning process or the siphon cleaning process starts. Since the toilet lid 32 is closed in this jet washing process or siphon washing process, even a relatively loud washing sound is prevented from being transmitted to the surroundings.
