  In order to solve the above-mentioned problem, a turn trap type flush toilet apparatus according to claim 1 of the present invention includes a trap portion whose front end portion is connected to a drain pipe portion extending from a bowl portion of a toilet body, and a toilet bowl. A turn-trap type water wash provided with a trap mechanism that is housed in the rear case body and rotates the end of the trap part up and down by a driving means to communicate the drain pipe part and the external drain pipe through the case body In the toilet device, the trap mechanism is characterized in that the end of the trap portion is driven to rotate up and down by a driving means with the front-rear direction of the toilet body as a rotation axis.

  In the turn trap type flush toilet apparatus according to claim 2 of the present invention, the driving means is connected to the trap portion to rotate the terminal end of the trap portion, and the rotation controllable arm member. And a motor for rotationally driving the motor.

  In the flush toilet device of the turn trap type according to claim 3 of the present invention, a drain port of the external drain pipe communicating with the trap mechanism is formed on a side outside the case body, and on the side of the toilet body, It has the relay member which formed the drainage channel which connects the said water distribution pipe and the inside of a case body.

  According to the turn trap type flush toilet apparatus according to claim 1 of the present invention, the trap mechanism is configured such that the end of the trap part is driven to rotate up and down by the driving means with the front-rear direction of the toilet body as the rotation axis. The end of the trap part when discharging filth and washing water is also configured to be rotatable and reversible around the front and back direction of the toilet body, and rotates on a plane perpendicular to the front and rear direction of the toilet body. It is not necessary to provide a space for rotating the trap portion at the rear portion. Therefore, the length of the toilet body in the front-rear direction can be shortened, and the space for the turn-trap flush toilet apparatus can be further reduced.

  According to the turn trap type flush toilet apparatus according to claim 3 of the present invention, in addition to the effect of claim 1 described above, the drain outlet of the external drain pipe communicating with the trap mechanism is located laterally outside the case body. Since the relay member is formed on the side of the toilet body and has a drainage passage that communicates the water distribution pipe and the inside of the case body, the width of the case body corresponds to the rotation in the width direction of the trap portion. The length in the front-rear direction can be shortened while maintaining the width of the conventional toilet body.

  An embodiment of the present invention will be described with reference to FIGS. 1 and 2, 1 is a bowl, 2 is a drain pipe section, 3 is a case body, 3a is a receiving section, 5 is a discharge port, 9 is a motor, 10 is a trap section, 11 is a rotating shaft section, 12 is a terminal end, 15 is a transmission belt, 16 is an arm member, 16a is a body portion, 16b is a hose clamping portion, 16c is a pulley portion, 17 is a trap hose, 18 is a termination member, 20 is a cabinet, 21 is a drainage channel, and 40 is an external It is a drain pipe.

  FIG.1 and FIG.2 is the longitudinal cross-sectional view and the cross-sectional view which respectively showed the outline of the flush toilet apparatus in this embodiment. As shown in FIGS. 1 and 2, a drain pipe 2 extends from a drain port 1 a at the bottom of the bowl 1 toward the back of the toilet. Between the terminal end of the drain pipe section 2 and the outlet 5 at the bottom of the toilet connected to the external drain pipe 40, a bellows-like stretchable and bendable trap section 10 is provided. The trap portion 10 is accommodated in a case body 3 called a chute that communicates with the external drain pipe 40. The end 12 of the trap unit 10 is connected to an arm member 16, and the arm member 16 is electrically connected to a control unit (not shown) and is rotated by a motor 9 that is controlled to rotate about the front-rear direction of the toilet body as a rotation axis. Since the arm member 16 is rotated by the operation of the motor 9, the terminal end 12 as a free end is configured to be rotatable and reversible on a plane perpendicular to the front-rear direction of the toilet body. Is done. In this way, the trap mechanism is formed by the trap portion 10 and the motor 9 and the arm member 16 that transmits the rotation of the motor 9 to the trap portion 10. Details are described below.

  The trap portion 10 is composed of a trap hose 17 imparted with bending flexibility by a bellows structure, and a relatively hard resin or metal end member 18 attached to and closely attached to the end 12 of the trap hose 17. One end portion 16 a of an arm member 16 that transmits the rotation of the rotary shaft portion 11 is fixedly attached to the rigid terminal member 18.

  One end of the trap hose 17 is slidably connected to the terminal end of the drain pipe portion 2 to be a fixed end, and the case body 3 on the terminal end side of the drain pipe portion 2 is connected to the outside of the trap hose 17. An opening substantially equal in diameter is formed, and the trap hose 17 is inserted and accommodated in the case body 3 through this opening. The material of the trap hose 17 is not particularly limited, and an appropriate material rich in elasticity that can be expanded and contracted and bent without being bent, such as resin and rubber, can be adopted, as shown in this embodiment. It may not be a bellows structure.

  The end 12 of the trap portion 10, which is the other end of the trap hose 17, has an arcuate curved surface, and sewage flows out from the lower edge in the rotational direction of the trap portion 10 and flows out laterally and rearwardly. This is effectively prevented.

  The arm member 16 includes a rod-shaped main body portion 16a, a ring-shaped hose clamping portion 16b provided at one end portion of the main body portion 16a, and a central portion that is pivotally supported by the rotary shaft portion 11 at the other end portion of the main body portion 16a. And a disc-shaped pulley portion 16c. The hose clamping portion 16b is composed of a pair of opposing frames with the inner peripheral edge having a semicircular arc shape, and the end member 18 is sandwiched between the two frames, and both ends are clamped with screws or the like.

  At the bottom of the case body 3, a motor 9a having a shaft 9a having a rotation axis in the front-rear direction of the toilet body is installed, and a pulley 13 is provided at the tip of the shaft 9a so as to rotate integrally with the shaft 9a. The connection is fixed. The rotation of the pulley 13 is transmitted to the pulley portion 16b by the transmission belt 15. Since this pulley portion 16b is pivotally supported by the rotating shaft portion 11, when the motor 9 is driven to rotate the pulley 13, the force is transmitted to the pulley portion 16b by the transmission belt 13, The arm member 16 rotates around the rotation shaft portion 11. Since the motor 9 is electrically connected to the control unit and can be rotated in both forward and reverse directions, the arm member 16 can also be controlled to be rotatable about the rotation shaft portion 11.

  With the configuration as described above, the end 12 of the trap portion 10 when discharging the filth rotates on a plane perpendicular to the front-rear direction of the toilet body, so the trap portion 10 is placed at the rear of the toilet body. There is no need to provide a space for rotation. Therefore, the length of the toilet body in the front-rear direction can be shortened, and the space for the turn-trap flush toilet device can be further reduced.

  In the present embodiment, the driving means for the terminal end 12 of the trap unit 10 includes an arm member 16 that is connected to the trap unit 10 and rotates the terminal end 12 of the trap unit 10, and can be controlled to rotate. Since it is equipped with a motor that rotates, the rotation of the trap part can be controlled via the arm member by controlling the rotational drive of the motor, and the rotation control of the end of the trap part can be easily performed with a simple structure. It can be carried out.

  By the way, in the turn trap type flush toilet apparatus in the present embodiment, when the drain outlet 5 is installed in the case body 3 as in the conventional turn trap type flush toilet apparatus as shown in FIG. Since the trap part 10 rotates up and down in the width direction with respect to the toilet body as described above, the width of the case body 3 needs to be widened to secure a space for rotation depending on the length of the trap hose 17. As a result, the width of the toilet body may increase. In this case, since the trap part 10 normally rotates only in one width direction, the width direction of the toilet body becomes significantly asymmetric in the width direction when the space to be widened and increased only in that direction is minimized. If the width of the toilet body is increased by making the width direction substantially equal to the left and right, an unnecessary space is generated in the case body 3 and the width of the toilet body is further increased.

  Therefore, in this embodiment, as shown in FIG. 2, the outlet 5 which is the opening of the external water distribution pipe 40 is installed on the side of the toilet body, and the cabinet 20 adjacent to the side of the toilet body. It was set as the structure enclosed in. That is, a container-shaped receiving portion 3a for receiving the waste discharged from the terminal end 12 by the rotation of the trap portion 10 is formed on the side portion of the case body 3 on the side where the trap portion 10 rotates. The part 3a is inclined downward in the lateral direction, and is connected to a relay member 21 installed in the cabinet 20 and having one end extending into the toilet body. The relay member 21 is preferably made of a flexible member such as rubber in order to be able to cope with a change in the drainage pitch in the field construction.

  With such a configuration, it is not necessary to increase the width of the case body 3 in response to the rotation of the trap portion 10 in the width direction, and the length in the front-rear direction is shortened while maintaining the width of the conventional toilet body. can do.

  In the normal state in which the trap mechanism as described above does not operate, the turn trap type flush toilet apparatus according to the present embodiment is arranged with the end 12 of the trap portion 10 facing upward, and the end 1 of the trap portion 10 is located inside the bowl 1. Water is stored at the height (water supply line) and sealed. When a discharge operation is input via a switch or the like after the stool, a solenoid valve (not shown) is opened, and cleaning water is supplied into the bowl 1 through this operation. Thereafter, the motor 9 is operated by the control unit, and the rotary shaft unit 11 is rotated to rotate the free end of the trap unit 10 approximately 90 ° (in the direction of the arrow in FIG. 1) laterally with respect to the front-rear direction of the toilet body. As the end 12 of the trap portion 10 rotates, the filth in the bowl 1 flows out from the end 12 to the receiving portion 3a in the case body 3 together with the cleaning water. Since the receiving portion 3a is inclined downward toward the side and is connected to the relay member 21, the filth and washing water flow out toward the external drain pipe 40 through the relay member 21, and the toilet bowl. Discharged outside.

  After the filth is completely discharged, the rotating shaft portion 11 is reversely rotated by the motor 9, the trap portion 10 is reversed to return to the initial state, and the water is again stored in the bowl 1 up to the water supply line and sealed. . Then, the solenoid valve is closed.
