Description

  The present invention relates to a turn-trap flush toilet.

  Conventionally, the open end of the movable trap connected to the drainage port of the toilet bowl is rotated up and down by a motor drive in the discharge chamber leading to the sewer pipe, thereby discharging the waste in the toilet bowl and sealing water in the toilet bowl. There is known a flush toilet that performs the above (see, for example, Patent Document 1).

Japanese Patent Laid-Open No. 11-210054

  In the conventional example of Patent Document 1, the flush toilet is required to discharge the filth to the sewer pipe using the wash water and transport the filth to the far side of the sewage pipe.

  The transport distance of filth varies depending on the installation slope and diameter of the sewage pipe, the amount of filth, the amount of flushing water in the toilet bowl, and the like. In this case, if the transport distance is short, the sewage stays inside the sewage pipe and causes clogging of the sewage. Therefore, each manufacturer determines the cleaning method and the amount of cleaning water for the toilet equipment.

  However, in the toilet bowl 1 provided with the water splash prevention part 9, as shown in FIG. 5, the filth B once falls on the water splash prevention part 9 and then rolls down to the bottom of the toilet bowl 1. At this time, the water W collected in the toilet bowl 1 is divided into water W1 on the upstream side of the filth B and water W2 (water on the movable trap 2 side) on the downstream side of the filth B with the filth B as a boundary. When toilet bowl cleaning is performed, the filth B flows through the sewer pipe 3 while maintaining this water balance substantially constant. At this time, the filth B is pushed and transported by the water W1 on the upstream side. That is, the water W2 located downstream of the filth B does not contribute to the conveyance of the filth B. Moreover, since the filth B is located at the bottom of the toilet bowl 1, the conveyance distance of the filth B in the sewer pipe 3 is shortened by the long conveyance distance to the open end 2b of the movable trap 2. Therefore, conventionally, it is necessary to increase the amount of washing water supplied to the toilet bowl 1, and there is a problem that water saving cannot be achieved.

  This invention is made | formed in view of said situation, The place made into the objective is providing the flush toilet which is easy to extend the conveyance distance of filth for a long time with little washing water quantity.

  In order to solve the above-mentioned problem, the present invention is configured to rotate the open end of a movable trap connected to a drain outlet of a toilet bowl up and down by a motor drive in a discharge chamber that communicates with a sewer pipe. This is a turn trap type flush toilet that discharges filth and seals water in the toilet bowl, and is provided with water receiving means capable of storing and draining a certain amount of water in the discharge chamber. During the rotation of the open end of the movable trap from the upward sealing position to the downward discharge position, a fixed amount of water discharged from the movable trap is received and temporarily stored. Is rotated to the discharge position, and is in a drained state in which the temporarily stored water is discharged.

The water receiving means includes a water receiving container rotatably attached to a wall surface in the discharge chamber, and the water receiving container from the rotational position where the water trapping state enters the water storage state in conjunction with the upward rotation of the movable trap. It is preferable to have an interlocking rotating mechanism that rotates the rotating position to the drainage state.

  The water receiving means includes a water receiving container rotatably attached to the wall surface of the discharge chamber, and a rotational position where the water receiving state is maintained until the open end of the movable trap rotates to a downward discharge position. And an open / close spring that allows the water receiving container to rotate to the rotational position where the drainage state is caused by the weight of the temporarily stored water after the open end of the movable trap is rotated to the discharge position. It is preferable to have.

  The flush toilet of the present invention makes it easy to extend the filth transport distance for a long time with a small amount of washing water.

It is side surface sectional drawing of a flush toilet provided with the water receiving means of one Embodiment of this invention. It is a side view of the water receiving container which comprises the water receiving means same as the above. It is the schematic explaining the balance of the water quantity of the water which is upstream from filth, and the water which is downstream from filth. It is explanatory drawing of the modification of a water receiving container same as the above. It is explanatory drawing of a prior art example.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  As shown in FIG. 1, the flush toilet A of this embodiment has one end 2a of the movable trap 2 connected to the drain port 1a of the toilet bowl 1 and the other end of the movable trap 2 as an open end 2b. This is a turn trap type flush toilet that drains waste in the toilet bowl 1 and seals water in the toilet bowl 1 by rotating the open end 2b up and down in a discharge chamber 4 communicating with the sewer pipe 3 by driving a motor. . 9 in the figure is a water splash preventing part.

  The movable trap 2 has a bendable bellows structure with a cylindrical cross section. The rotating shaft 2c of the movable trap 2 is coupled to a motor (not shown) that is electrically connected to a control unit (not shown) and controlled in operation. With the rotation of the rotating shaft 2c driven by the motor, the open end 2b of the movable trap 2 can be rotated or bent up and down around the rotating shaft 2c.

  Behind the toilet bowl 1 is provided a discharge chamber 4 leading to the sewer pipe 3. Inside the discharge chamber 4 is provided water receiving means 5 capable of storing and draining a certain amount of water.

  The water receiving means 5 includes a water receiving container 6 rotatably attached to the wall surface 4 a in the discharge chamber 4, and an interlocking rotating mechanism 7 that drives the water receiving container 6 in conjunction with the rotating shaft 2 c of the movable trap 2. It consists of.

  As shown in FIG. 2, the water receiving container 6 is disposed along the wall surface 4 a of the discharge chamber 4 facing the open end 2 b of the movable trap 2. The water receiving container 6 is composed of a cage-like plate-like object 6 a that is opened toward the wall surface 4 a of the discharge chamber 4. The lower end portion of the plate-like object 6a is rotatably attached to the wall surface 4a of the discharge chamber 4 via a hinge drive portion 7a.

  The hinge driving portion 7a of the water receiving container 6 constitutes an interlocking rotation mechanism 7 that rotates in synchronization with the rotating shaft 2c of the movable trap 2, and is interlocked with the bending of the movable trap 2 to bend the movable trap 2. The water receiving container 6 is driven to rotate later. The plate-like object 6 a constituting the water receiving container 6 is arranged so that the movement trajectory of its tip does not interfere with the movement trajectory of the open end 2 b of the movable trap 2. In this example, the hinge driving portion 7a of the water receiving container 6 is started so that the water receiving container 6 starts rotating after the filth B passes through the movable trap 4 with a slight delay from the time when the movable trap 2 starts to bend. Is a mechanism that rotates in conjunction with the rotating shaft 2c of the movable trap 2 with a delay. Then, a fixed amount of water flowing out from the movable trap 2 in the initial stage of toilet flushing is received by the water receiving container 6 and temporarily stored, and the water receiving container 6 further rotates downward as indicated by the phantom line in FIG. Thus, the accumulated water W3 temporarily stored in the tank flows out.

  According to the above configuration, in the toilet bowl 1 provided with the water splash prevention unit 9, the waste B once falls on the water splash prevention unit 9 as shown by the arrow c in FIG. It falls to the bottom of the pot 1. In the stage before toilet bowl washing, the water W stored in the toilet bowl 1 is composed of water W1 located upstream from the filth B and water W2 located downstream from the filth B as shown in FIG. It is divided into.

  When the open end 2b of the movable trap 2 is slightly rotated from the upward position to the slightly rotated rotational position P2 at the start of toilet cleaning, a part of the water W2 downstream from the waste B from the open end 2b of the movable trap 2 Is discharged. This water W2 is not discharged to the sewage pipe 3 side but is stored in the water receiving container 6 and stored as water W3 (see FIG. 2). At this time, the amount of water on the downstream side of the filth B in the movable trap 2 is reduced, and the amount of water on the upstream side of the filth B is increased by passing water into the toilet bowl 1, so that the filth B becomes an arrow e in FIG. As shown by, it is pushed to the downstream side and becomes easy to move to the bottom side of the movable trap 2. That is, the filth B easily moves from the position indicated by the solid line in FIG. 3 to the position indicated by the broken line.

  Further, when the movable trap 2 rotates to the downward discharge position P3, all the filth B in the toilet bowl 1 is discharged into the sewer pipe 3. Immediately after the discharge of the filth B, the water receiving container 6 rotates in the direction indicated by the arrow f in FIG. As a result, the water W3 stored in the water receiving container 6 is discharged into the sewer pipe 3 and contributes to the conveyance of the filth B. That is, when considering the balance between the amount of water upstream of the filth B and the amount of water downstream of the filth B, the amount of water upstream of the filth B increases due to the discharge of the accumulated water W3, and the transport distance of the filth B is increased. Can do. As a result, it becomes easy to extend the conveyance distance of the filth B without increasing the supply amount of the washing water into the toilet bowl 1, and the filth B is not easily clogged in the sewer pipe 3.

  Further, in this example, since the rotation of the water receiving container 6 is linked with the motor drive of the rotating shaft 2c of the movable trap 2, there is no need to provide a dedicated motor for driving the water receiving container 6, and the structure There is also an advantage that can be simplified.

  In the above embodiment, the water storage space 8 is formed between the plate-like object 6a constituting the water receiving container 6 and the wall surface 4a of the discharge chamber 4. However, as shown in FIG. The wall surface 4a may be constituted by a single cage 5 which is a separate body. Further, the interlocking rotation mechanism 7 is not provided, and the water receiving container 6 may be driven by a motor different from the movable trap 2.

  As another embodiment, a torsion spring (not shown) is attached to the hinge driving portion 7a of the water receiving container 6 as an opening / closing spring, and when the amount of water stored in the water receiving container 6 exceeds a certain level, the water receiving container 6 temporarily stores water. It is good also as a mechanism in which the water W3 rotates by the weight of the water W3 and the water W3 flows out. The spring force of this torsion spring is set as follows. Until the movable trap 2 rotates to the downward discharge position P3, the water receiving container 6 is held at the rotation position (upward position indicated by the solid line in FIG. 2) where the water receiving container 6 is stored. After the movable trap 2 is rotated to the discharge position P3, the water receiving container 6 is allowed to rotate to a rotation position (downward position indicated by an imaginary line in FIG. 2) where the water receiving container 6 is accumulated and drained due to the weight of the water W3. As a result, when the filth B passes through the movable trap 2, a certain amount of accumulated water W3 is stored in the water receiving container 6. After the filth B passes through the movable trap 2, the water receiving container 6 opens against the spring force and the accumulated water W <b> 3 is discharged toward the sewer pipe 3. After the accumulated water W3 is discharged, the water receiving container 6 automatically returns to the original upward position by the spring force. Therefore, it is not necessary to interlock the hinge drive part 7a of the water receiving container 6 with the motor drive, and the structure can be further simplified.

  In the above-described embodiment, water is stored in the water receiving container 6 when the movable trap 2 reaches the obliquely fine rotation position P2, but water is stored in the water receiving container 6 when the movable trap 2 is turned sideways. It may be configured.
