Description

  The present invention relates to a movable trap-type flush toilet having a configuration in which a trap section operates to drain water.

  This type of movable trap flush toilet is connected to the bowl drainage channel in the trap storage chamber that follows the bowl drainage channel of the toilet bowl body, and the drain opening is pivoted up and down. There is a configuration in which the portion is accommodated (see, for example, Patent Document 1).

  In such a movable trap type flush toilet, when the drain opening which is the free end of the trap portion is in an upward state (water supply posture), the wash water is stored in the bowl, and the drain opening is in a downward state (drain posture). In some cases, sewage is discharged from the drain opening.

  Wastewater, such as sewage discharged from the drain opening when the trap is in the draining posture, will flow to the external outlet through a discharge path formed in the inner bottom of the trap storage chamber. Yes.

  On the other hand, when the trap is in the water supply position, there is no large amount of drainage from the drainage opening, but water that overflows from the discharge edge at the lower end of the drainage opening (overflow water) falls into the lower drainage channel There is. If there is a puddle in the drain, if overflow water falls into the puddle, a dripping sound may be generated, which may cause the user to misunderstand that a leak has occurred.

  In order to prevent the occurrence of such dripping sound, various measures as shown in Patent Document 1 and the like have been adopted. The technique of patent document 1 distributes the overflow water from the drain opening part of a trap part into two directions, and makes it a small water droplet. In addition, a technique has been proposed in which the shape of the opening is changed so that overflow water is transmitted to the rear wall of the trap storage chamber.

JP 2008-267003 A

  However, any of the above-mentioned conventional measures guides the overflow water from the drain opening of the trap part downward so as to make as little sound as possible. There are cases where it cannot be easily handled. In addition, there is a possibility that it cannot cope with a variation error in the stop position due to repeated vertical movement of the trap portion. That is, if there is a design change or the like, there is a possibility that guidance that does not generate sound cannot be performed.

  In this way, in the past, there was a possibility that dripping noise could not be prevented as long as overflow water overflowed from the drainage opening, so it was fundamental to prevent overflowing water from overflowing from the drainage opening when in a water supply position. A new solution was sought.

  The present invention has been proposed in view of such circumstances, and an object of the present invention is to provide a movable trap-type flush toilet that can reduce the generation of dripping sound due to falling of overflow water.

  In order to achieve the above object, the movable trap flush toilet of the present invention is provided subsequent to the drainage channel of the bowl of the toilet bowl body, the connection opening at one end is connected to the drainage channel, and the drainage opening at the other end In the movable trap type flush toilet having a cylindrical trap part that operates so that the part can be drained, the trap part is designed to maintain a water supply posture with the opening of the drain opening facing upward, There is a bypass port that leads from the inside of the trap part to the outside at a position that is lower than the discharge edge of the opening of the drainage opening when in the water supply posture, and it is discharged from the bypass port inside the toilet body. A bypass flow path for guiding the discharged water to the lower side is formed.

  According to the movable trap flush toilet of the present invention, since it has the above-described configuration, it is possible to reduce the generation of dripping sound due to the fall of overflow water.

It is a longitudinal cross-sectional view of the movable trap type flush toilet which concerns on one Embodiment of this invention. It is a principal part schematic longitudinal cross-sectional view and a partially expanded longitudinal cross-sectional view of a movable trap type flush toilet. (A) (b) is a longitudinal cross-sectional view of the movable trap type flush toilet which concerns on other 2 embodiment of this invention.

  Embodiments of the present invention will be described below with reference to the accompanying drawings. First, a basic configuration of a movable trap type flush toilet 1 (hereinafter referred to as flush toilet 1) according to a plurality of embodiments described below will be described.

  The flush toilet 1 shown in FIGS. 1, 2, and 3 (a) and 3 (b) is provided subsequent to the drainage channel 12 of the bowl 11 of the toilet body 10, and the connection opening 31 at one end is connected to the drainage channel 12. It has a cylindrical trap portion 30 that is connected and has a drain opening 32 at the other end that can be drained.

  The trap portion 30 is configured to maintain the water supply posture with the opening of the drainage opening portion 32 facing upward. The trap section 30 has a bypass port 36 that leads from the inside of the trap section 30 to the outside at a position that is lower than the discharge edge 32a (see FIG. 2) of the opening of the drain opening section 32 in this water supply posture. ing. A bypass channel 50 is formed inside the toilet body 10 to guide the discharged water discharged from the bypass port 36 (see FIG. 2) downward.

  Next, the configuration and features of the flush toilet 1 shown in FIGS. 1 and 2 will be described in detail.

  As shown in FIG. 1, the flush toilet 1 is a wall-draining Western-style toilet that drains sideways with respect to an external drain pipe 2 that is embedded in a wall 3 and extends in the vertical direction. This external drainage pipe 2 can be shared by upper and lower floors in an apartment or the like. In the following description, the back side (right side in FIG. 1) when a person sits on the flush toilet 1 will be described as “rear” and the chest side (left side in FIG. 1) will be described as “front”.

  The toilet body 10 of the flush toilet 1 is installed and fixed on the floor 4. In addition, an openable / closable lid 6 is attached to the upper surface of the toilet body 10.

  A bowl 11 for storing washing water and sewage is provided in the toilet body 10. A rim 13 for supplying cleaning water into the bowl 11 is formed on the inner periphery of the upper portion of the bowl 11. In addition, a horizontal tubular drainage channel 12 that extends in the direction of the external drainage pipe 2 is formed in the lower part of the bowl 11.

  A trap storage chamber 20 following the drainage channel 12 is provided in the toilet body 10. In the trap storage chamber 20, a flexible trap portion 30 connected to the drainage channel 12 of the bowl 11 is provided. As the trap part 30, as shown in FIG. 1, what was formed, for example with the bellows-like hose can be used. The trap storage chamber 20 is configured to surround the trap portion 30, receive the discharged water discharged from the trap portion 30 at the inner bottom portion 21, and discharge it to the outside, thereby preventing the diffusion of the odor to the outside. Also bears.

  In the trap storage chamber 20, the trap section 30 has a water supply posture in which the drain opening 32, which is a free end, faces upward, with the connection opening 31 connected to the drain 12 of the bowl 11 as a fulcrum, and slightly downward laterally It is arranged to be rotated up and down between the drainage posture. In addition, in FIG. 1, the trap part 30 at the time of a water supply attitude | position was illustrated with the continuous line, and the trap part 30 at the time of a drainage attitude | position was illustrated with the dashed-two dotted line.

  As shown in FIG. 1, a support ring 33 is fitted on the outer periphery of the drain opening 32 of the trap portion 30. The support ring 33 is connected to an arm 35 of a rotation shaft 34 that is rotatably supported by the side wall portion of the trap storage chamber 20. As the arm 35 rotates, the drain opening 32 of the trap portion 30 to which the support ring 33 is attached is rotated up and down.

  Such an operation of the trap unit 30 is performed by driving the rotating shaft 34 with the electric motor 41. In addition, an electromagnetic valve 42 is provided in a pipe for supplying cleaning water to the rim 13 of the bowl 11. The electric motor 41 and the electromagnetic valve 42 are controlled by the control device 43.

  Thus, the drive mechanism comprised including the electric motor 41 etc. performs the following operations. That is, when a washing operation is performed after the stool, the electromagnetic valve 42 is opened and washing water is supplied from the rim 13 into the bowl 11, and then the electric motor 41 is rotated forward so that the trap unit 30 is in a draining posture. It is turned down. In addition, after a predetermined time of the cleaning operation, the electric motor 41 is reversed and the trap unit 30 is rotated upward to the water supply posture, and then the electromagnetic valve 42 is closed to supply the cleaning water from the rim 13 into the bowl 11. Is stopped.

  When the trap unit 30 is in the upper position (water supply posture), the water is sealed, and as shown by the broken line in FIG. 1, as shown by the broken line in FIG. Is stored.

  As described above, the trap portion 30 is formed with the bypass port 36 (see FIG. 2). The bypass port 36 is formed at a position lower than the discharge edge 32a (see FIG. 2) of the opening of the drain opening 32, that is, the lower edge of the opening of the drain opening 32 in the water supply posture. A bypass channel 50 made of a tube is connected to the bypass port 36. Details of the bypass channel 50 will be described later. In addition, level H2 shown with the dashed-two dotted line in FIG. 1 etc. is a height level of the discharge edge 32a.

  In the trap storage chamber 20, there is a space for storing the trap portion 30 surrounded by the front wall portion 26, the rear wall portion, both side wall portions, the bottom portion (inner bottom portion 21), and the ceiling portion. Is formed. Further, an opening 24 (see FIG. 2) is provided at the lower portion of the front wall portion 26. One end (connection opening 31) of the trap portion 30 stored in the trap storage chamber 20 is connected to the drainage channel 12 of the bowl 11 through the opening 24. In addition, an external outlet 25 leading to the external drain pipe 2 is opened at the lower part of the rear wall.

  A surface portion of the inner bottom portion 21 from the front wall portion 26 to the external discharge port 25 constitutes a discharge path 23 that guides discharged water discharged from the trap portion 30 to the outside. The discharge path 23 has a stepped shape that is one step lower on the downstream side. As shown in FIG. 2, a front discharge path 23a is formed on the front side and a rear discharge path 23b is formed on the rear side through the step wall 22. . This rear discharge path 23 b communicates with the external discharge port 25.

  When the trap portion 30 is in the draining posture, that is, when the drain opening 32 that is the free end is in the lower position, the drain opening 32 is in contact with or close to the road surface of the rear discharge passage 23b. The opening faces downward. In the draining posture, the trap portion 30 is in such a state, and the sewage and the washing water are discharged from the drain opening 32 to the discharge path 23.

  And the discharged water discharged | emitted from the trap part 30 is smoothly drained to the external drainage pipe 2 through the external discharge port 25 along the inclined surface of the back discharge path 23b. Particularly in the present embodiment, when the trap portion 30 is rotated downward, the drain opening portion 32 falls into the rear discharge passage 23b located on the downstream side of the step wall 22 so that the opening of the drain opening portion 32 is further downward. Therefore, the discharged water is easier to flow from the drain opening 32.

  Next, the configuration of the bypass channel 50 in the present embodiment will be described with reference to FIGS. 1 and 2.

  As described above, the bypass channel 50 is connected to the bypass port 36 of the trap unit 30. As shown in the enlarged view of FIG. 2, one end (inflow port 51) of a bypass channel 50 made of a tube is connected to the bypass port 36. The bypass channel 50 connected to the bypass port 36 extends from the drain opening 32 side to the connection opening 31 side along the outer surface of the trap part 30. Note that the bypass flow path 50 may also be made extendable so that the position of the outlet 32 does not fluctuate according to the expansion / contraction of the bellows of the trap portion 30.

  The amount of water that is supplied to the bowl 11 when the trap unit 30 is in the water supply posture is set so that the water level H1 is at the height level of the bypass port 36. When the cleaning water is supplied, the overflow water 8 is slightly overflowed to generate overflow water 8. The overflow water 8 is discharged from the bypass port 36.

  As shown in FIG. 2, the discharged water flows through the bypass channel 50 in the direction of the connection opening 31 (rotation fulcrum) of the trap unit 30 and is discharged from the outlet 52 of the bypass channel 50. The discharged water discharged from the outlet 52 falls to the front discharge path 23a of the discharge path 23 and merges, and flows to the downstream external discharge port 25 through the front discharge path 23a and the rear discharge path 23b.

  Thus, since this flush toilet 1 is provided with the bypass port 36 and the bypass flow path 50, the overflow water 8 can be induced | guided | derived to the front discharge path 23a which is a place where a water pool is hardly possible. Moreover, since the water level H1 at the time of a water supply attitude | position is a position lower than the level H2 of the discharge edge 32a of the opening of the drain opening 32, unless the overflow water 8 from the drain opening 32 is too strong in the water supply Does not occur.

  In this way, it is possible to reduce the generation of dripping sound due to the fall of the overflow water 8. Further, since the discharge water discharged from the outlet 52 of the bypass flow path 50 is disposed so as to go to the discharge path 23, the overflow water 8 is joined to the flow path of the discharge water discharged in the drainage posture. Can be drained smoothly.

  Furthermore, since the bypass flow path shown in the present embodiment is arranged so as to extend from the drainage opening 32 side to the connection opening 31 side along the outer side surface of the trap part, Due to the gradient, the overflow water 8 can be guided to a place where water cannot be accumulated.

  Moreover, in order not to generate dripping sound due to the overflow of the overflow water 8, the bypass channel 50 may be formed and arranged as shown in FIGS. 3 (a) and 3 (b).

  The bypass flow path 50 in FIG. 3A is arranged along the upper end of the trap portion 30 as in FIG. 1, but is shorter than that in FIG. 1, and its outlet 52 is at the center of the trap portion 30. It is arranged to be located in the bellows part. The overflow water 8 discharged from the bypass port 36 is discharged from the outlet 52 of the bypass channel 50, and the discharged water falls along the outer peripheral surface (bellows portion) of the trap portion 30.

  Thus, if the overflow water 8 is transmitted along the outer surface of the trap part 30, the fall distance to the discharge path 23 can be shortened. Since it falls from such a low position, even if the water is pooled in the front discharge path 23 and the discharged water falls into the water pool, a dripping sound that resonates outside does not occur. Further, since the bypass flow path 50 can be shortened, the bypass flow path 50 does not interfere with the vertical movement of the trap portion 30 and is not easily displaced by the rotation. The bypass channel 50 can also be formed of a hard material.

  Further, the bypass flow path 50 of FIG. 3B is hung downward so that the discharged water from the outlet 52 merges with the front discharge path 23. This can also reduce the fall distance to the discharge path 23, so that even if the discharged water falls into the water pool of the discharge path 23, a dripping sound that resonates outside cannot be generated. The bypass channel 50 is preferably formed of a soft material so that it can withstand the vertical rotation of the trap portion 30.

  Thus, if the bypass channel 50 is arranged so that the outlet 52 thereof is close to the surface of the discharge channel 23, the possibility that a dripping sound is generated is low. If the outlet 52 is arranged at a low position, the bypass flow path 50 may be joined to the rear discharge path 23b where water can be easily retained. Further, the outlet 52 may be brought into contact with the wall surface of the trap storage chamber 20 so that the discharged water is transferred from the wall surface.

  In the various embodiments described above, the example in which the bypass channel 50 is configured by a tube has been described. However, in the case of a tube made of a particularly soft material, the outlet 52 is selected at a position where no dripping sound is generated. And can be applied to flush toilets of various shapes and dimensions.

  Further, the bypass channel 50 may be formed of a concave groove body. For example, the bypass channel 50 made of the tube shown in FIGS. 1 and 2 may be replaced with a concave groove body. In addition, without providing a tube or a ditch | groove body, you may make it discharge | emit directly to the exterior from the bypass port 36 of the trap part 30, and may make it fall along the outer surface of the trap part 30. That is, the outer surface of the trap part 30 may be used as the bypass channel 50.

  Further, the bypass flow path 50 may not be joined to the discharge path 23. For example, the outlet 52 of the bypass channel 50 may be directly connected to the external drain pipe 2.

  Although the wall drain type flush toilet 1 has been exemplified in the above embodiment, the present invention can also be applied to a floor discharge type Western style toilet.
