  The present invention relates to a flush toilet. More specifically, the present invention relates to a turn trap type flush toilet.

  2. Description of the Related Art Conventionally, flush toilets installed in toilets such as houses have been provided with various configurations and structures. For example, a flush tank has a low tank, and water is instantaneously discharged from the low tank to discharge waste and bowl. It is known to perform cleaning. In this low tank water supply type flush toilet, when the stored water in the low tank provided at a position higher than the bowl is supplied into the bowl, the stored water is used for sealing water connected to the bowl by the water head pressure of the water tank. It has a structure to get over the trap part and discharge filth.

  However, a low tank water supply flush toilet requires a large head pressure to discharge filth, so it is indispensable to install a low tank. For this reason, a low tank occupies a part of it in a narrow toilet space. Will be. In addition to toilets, accessories such as hand-washers and storage devices for toiletry goods are also required in the toilet space, so it is not preferable to divide the space into the low tank.

  On the other hand, in apartment houses such as condominiums, from the viewpoint of design, not only the problem of space in the toilet, but also a floor drainage system that allows drainage to flow downward may not be adopted. In this case, as described in Patent Document 1 below, a method of discharging wastewater containing filth into a drainage pipe provided outside the wall is adopted by a wall drainage method in which a drain outlet is provided on the wall side.

  That is, as shown in the longitudinal sectional view shown in FIG. 4 of the present application, the toilet body 9 is installed on the floor surface, and the lid 8 is attached to the upper surface of the toilet body 9 so as to be freely opened and closed. The wall W is embedded with a vertical drainage pipe 7 extending in the vertical direction. The vertical drainage pipe 7 is shared by the upper floor and the lower floor in an apartment or the like.

  A bowl 6 is provided in the toilet body 9, and a rim 5 for supplying washing water to the bowl 6 is formed around the inside of the upper portion of the bowl 6. A drainage channel 4 is formed toward the drainage pipe 7. A trap case 3 connected to the drainage channel 4 is provided in the toilet body 9, and a flexible trap part in which the rear end opening 13 is connected to the drainage channel 4 is provided in the trap case 3. 1 is provided. The trap portion 1 is formed of, for example, a bellows-like hose, with the rear end opening 13 side as a fulcrum, the front end opening 11 has a substantially upward water supply posture (shown by a solid line) and a substantially horizontal drainage posture (two-dot chain line) It is possible to expand and contract freely and rotate up and down.

  A support ring 12 is fitted on the outer periphery of the tip opening 11 of the trap portion 1, and an arm 21 of the rotation shaft 2 rotatably supported by the side wall of the trap case 3 is connected to the support ring 12. The support ring 12 and the tip opening 11 are configured to rotate up and down by the rotation of the rotation shaft 2.

  The rotating shaft 2 is driven by an electric motor M, and a solenoid valve V is provided in a pipe for supplying cleaning water to the rim 5 of the bowl 6. The electric motor M and the electromagnetic valve V are controlled by a control device C. Be controlled. In other words, when the switch is turned on after the stool, the solenoid valve V opens, the cleaning water is supplied from the rim 5 into the bowl 6, and then the electric motor M rotates forward so that the trap portion 1 drains. Is done. In addition, a timer is activated after a predetermined time from the switch-on, and the electric motor M rotates backward so that the trap unit 1 enters a water supply state, the electromagnetic valve V is closed, and the rim 5 enters the bowl 6. The cleaning water supply is stopped.

The trap case 3 is provided with a drain pipe portion 32, and the drain pipe portion 32 is connected to the dredged drain pipe 7 with a gentle downward slope. Thus, if the wall drain type turn trap flush toilet is configured as described in Patent Document 1 below, the drain pipe portion 32 of the trap case 3 is connected to the dredged drain pipe 7 with a gentle downward slope. Accordingly, it is described that even when the trap portion 1 is rotated downward to a substantially horizontal drainage posture, dirty water can be smoothly drained into the drainage drain pipe 7.

  However, in the turn trap type flush toilet described in Patent Document 1, there is a gap between the tip opening 11 of the trap portion 1 and the rear wall portion 31 of the trap case 3 as schematically shown in FIG. Since it is formed, there is a problem that wastewater containing filth that should be discharged instantly leaks into the trap case 3. As a result, as schematically shown in FIG. 6 of the present application, there is a problem that the momentum of the drainage discharged to the drainage pipe portion 32 is deteriorated and the drainage is inferior.

  The present invention has been made to solve such problems, and it is intended to temporarily increase the discharge amount of waste water, increase the water flow, and improve the drainage and cleaning properties of waste water including filth. It is an object of the present invention to provide a turn-trap flush toilet that can be used.

In order to solve the above problems, the present invention takes the following technical means. That is, according to the first aspect of the present invention, the trap case is provided connected to the drainage channel of the bowl of the toilet bowl body, and the trap case is connected to the drainage channel and is turned up and down by the drive mechanism. In the turn trap type flush toilet provided with the trap part, the trap part is supplied with the upward water supply in the state of being supplied to the trap part before moving from the substantially upward water supply attitude to the substantially horizontal drainage attitude. After turning from the attitude temporarily further upward, it is turned downward, so that it becomes a substantially horizontal drainage attitude, and the drain pipe part of the trap case is connected to a wall drainage type drainage pipe. A flush toilet is provided.

  According to a second aspect of the turn trap flush toilet according to the second aspect, in addition to the invention according to the first aspect, the trap portion is made of flexible plastics. Examples of the flexible plastics include those obtained by processing a synthetic resin such as vinyl chloride resin, polypropylene, and polyethylene into a bellows-like hose.

  In addition to the invention according to claim 1, the turn trap type flush toilet according to claim 3 is configured such that the drive mechanism is an electric motor and the vertical rotation is controlled by a control device. This control device commands the water supply from the rim at the same time as the electric motor is reversely rotated so as to temporarily rotate further upward from a water supply posture in which the trap portion is almost upward by a switch operation. Thereafter, the electric motor is rotated forward to bring the trap portion into a draining posture, and after a predetermined time has elapsed by incorporating a timer or the like, the trap portion is returned to the water supply posture and water supply is stopped.

The turn trap type flush toilet according to the first aspect of the invention is as described above, and is provided in a trap case connected to the drainage channel of the bowl of the toilet body, and is trapped up and down by a drive mechanism. Before moving from a substantially upward water supply posture to a substantially lateral drainage posture, while the water is supplied to the trap portion, the portion is temporarily turned upward from the substantially upward water supply posture and then rotated downward. Since the drainage posture is substantially sideways, the water level from the rim temporarily moves above the normal water level, and the amount of cleaning water stored in the toilet increases only during the cleaning operation. After that, by moving to a sideways drainage posture, the stored water that has been temporarily increased is discharged all at once, improving the conveyance performance of filth, and drainage containing filth in a large water flow all at once into the drain pipe section. It can be washed away and poured into a drainage pipe.

  The turn trap type flush toilet according to claim 2 is as described above, and in addition to the effect of the turn trap flush toilet according to claim 1, the trap portion is made of flexible plastics. Molding is easy and durable.

  The turn-trap flush toilet according to claim 3 is as described above. In addition to the effects of the turn-trap flush toilet according to claim 1, the drive mechanism is an electric motor, and the control device is turned up and down. Therefore, after use is completed by incorporating a timer or the like, drainage can be made to flow and return to the original state by a one-touch switch operation.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a longitudinal sectional view showing a main part of a turn trap type flush toilet according to the present invention. In FIG. 1, the trap portion 1 a is composed of a flexible member that can be expanded and contracted, and can be moved up and down by controlling the rotation shaft 2 supported by the side wall of the trap case 3 a by a control device outside the figure. Is rotated. That is, the arm 21 is connected to the support ring 12a fitted on the outer periphery of the tip opening 11a of the trap portion 1a, and the rotation of the rotating shaft 2 is transmitted to the support ring 12a so that the support ring 12a and the tip opening 11a are vertically moved. It is configured to rotate.

  In the present embodiment, after the user has finished the use, when the switch is turned on to operate the non-illustrated control device, the control device commands water supply, and at the same time, the trap portion 1a is connected to the electric motor. From the substantially upward water supply posture shown in FIG. 1, as shown in FIG. 2, the support ring 12a and the tip opening 11a are instructed to be temporarily upward further. That is, the control device temporarily commands the electric motor to perform reverse rotation, and further directs the trap unit 1a upward, and then commands normal rotation of the normal operation. Move to the drainage posture. At this time, the tip opening 11a of the trap portion 1a moves along the rear wall portion 31a of the trap case 3.

  By doing in this way, the water level from the rim 5 (FIG. 4) temporarily moves above the normal water level, and the amount of cleaning water stored in the toilet increases only during the cleaning operation. Thereafter, by moving to the drainage posture shown in FIG. 3, the stored water increased temporarily is discharged at a stroke, so that the conveyance performance of the filth is improved, and the drainage pipe portion that drains the wastewater at a stroke with a large water flow. 32 can be swept away.

  By configuring as described above, it becomes possible to obtain drainage and washing performance similar to those of the low tank water supply method even if a turn trap type flush toilet is used, and further effectively use the space occupied by the low tank in the toilet. It is possible to save water and reduce noise.
