Since the toilet body 11 can be attached to the frame frame 7 after being hooked on 5, the flush toilet 1 can be easily installed.

  The sewer 33 may be provided on the toilet wall 3 as shown in FIG. 1, or may be provided on the toilet floor 47 as shown in FIG. And even if it is a case where the sewer 33 is provided in the wall 3, the height position of the said sewer 33 may be the height position of H1 shown in FIG. 1, and the height position of H2. Further, as shown in FIG. 5, in the case where the sewage port 33 is provided in the floor 47, the horizontal direction from the central portion of the toilet body 11 in the left-right direction is even when the distance from the wall 3 is substantially constant. May be unevenly distributed.

  That is, the boy's flush toilet 1 has a wall-mounted type in which the toilet body 11 is hung on the wall 3 corresponding to the sewage port 33 provided on the wall 3, and a toilet bowl corresponding to the sewage port 33 provided on the floor 47. There is a floor-mounted type in which the main body 11 is placed on the floor. Thus, the drain trap 35 is configured to be compatible with both wall-mounted and floor-mounted flush toilets.

  More specifically, the drain trap 35 is configured as shown in FIG. That is, the drain trap 35 is fitted (fitted) to the lower end portion of the connector 19 (not shown in FIG. 6) provided at the distal end portion of the projecting frame 7T in the main body frame 7 so as to be relatively horizontally rotatable. ) A box-shaped connection pipe 49 provided with a round pipe-like upper fitting connection portion 49 </ b> A protruding toward one end of the upper surface is provided, and a lower fitting connection portion 49 </ b> B is provided on the other end of the lower surface of the connection pipe 49. Is provided to protrude downward.

  The connection pipe 49 constitutes a chamber having a relatively large capacity, and the connection pipe 49 is used for cleaning the inner peripheral surface of the upper fitting connection portion 49A and the inner surface of the connection tool 19. A cleaning nozzle 51 is provided for injecting cleaning water so as to diffuse upward. The cleaning nozzle 51 receives the supply of cleaning water from the pump 31 and diffuses and jets the cleaning water upward.

  The supply path for supplying the cleaning water from the pump 31 to the spray nozzle 27 and the supply path for supplying the cleaning water to the cleaning nozzle 51 are branched and connected to the branch connection portion from the pump 31. There is provided a switching valve (not shown) that can freely switch the cleaning water to the spray nozzle 27 side or the cleaning nozzle 51 side. Therefore, washing water is jetted from the injection nozzle 27 to the water receiving recess 15 of the toilet body 11 to wash the water receiving recess 15, and the washing water is jetted from the cleaning nozzle 51 to fit the upper portion of the connection pipe 49. The inside of the portion 49A and the inside of the connection pipe 49 can be cleaned.

  The lower fitting connection portion 49B of the connection pipe 49 is fitted and connected to one rotation connection portion 53A of the U-shaped connection pipe 53 so as to be relatively horizontally rotatable. The other connecting portion 53B of the U-shaped connecting pipe 53 is fitted and connected to the one rotating connecting portion 55A of the first L-shaped pipe 55 so as to be relatively horizontally rotatable. The other end portion of the first L-shaped pipe 55 is oriented in a direction substantially orthogonal to the rotation connecting portion 55A and in a substantially horizontal direction, and the connecting portion 55B provided at the other end portion is the first one. The two L-shaped pipes 57 are inserted into and connected to the rotation connecting portion 57A of the L-shaped pipe 57 so as to be relatively rotatable. The connection portion 57B on the other end side of the second L-shaped pipe 57 is oriented in a direction substantially orthogonal to the rotation connection portion 57A.

  The connecting portion 57B of the second L-shaped pipe 57 is fitted and connected to one rotational connecting portion 59A of the third L-shaped pipe 59 so as to be relatively rotatable. The connecting portion 59B on the other end side of the third L-shaped pipe 59 is oriented in a direction substantially orthogonal to the rotational connecting portion 59A and is always oriented substantially in the horizontal direction. A drain pipe 61 connected to the sewage port 33 provided on the wall 3 is connected to the connection portion 59B of the third L-shaped pipe 59. The upper fitting portion 49A of the connection pipe 49 in the drain trap 35 is always connected to the connection tool 19 between the U-shaped connection pipe 53 and the protruding frame 7T of the frame body frame 7. Thus, an elastic member 63 such as a coil spring as an urging means for urging upward is interposed.

  With the above configuration, the connection pipe 49 can be rotated horizontally around the upper fitting portion 49A as a rotation axis, and the U-shaped connection pipe 53 can be rotated horizontally around the rotation connection portion 53A as a rotation axis. . The first L-shaped pipe 55 can be rotated horizontally around the rotation connecting portion 55A as a rotation axis. Accordingly, the connecting portion 55B of the first L-shaped pipe 55 can move in the direction approaching and separating from the wall surface of the wall 3 and the left-right direction along the wall surface (the direction perpendicular to the paper surface in FIG. 6). The connecting portion 55B can be oriented in a direction perpendicular to the wall surface of the wall 3 or in a horizontal direction inclined in the left-right direction.

  The connecting portion 57B of the second L-shaped pipe 57 that is rotatably connected to the connecting portion 55B of the first L-shaped pipe 55 is vertically moved with the rotational connecting portion 57A of the L-shaped pipe 57 as a rotation axis. The height position can be adjusted in the up-down direction by turning the head, and the connecting portion 57B is oriented in the up-down direction and horizontally oriented in the direction orthogonal to the rotation axis of the rotary connecting portion 57A. Can do. Therefore, the height position of the third L-shaped pipe 59 that is rotatably connected to the connecting portion 57B of the L-shaped pipe 57 can be adjusted. Then, by rotating the L-shaped pipe 59 around the rotation connecting portion 59A of the third L-shaped pipe 59, the drain pipe 61 connected to the connecting portion 59B of the L-shaped pipe 59 is connected to the wall surface of the wall 3. It can be adjusted to a horizontal posture so as to be orthogonal to.

  That is, as described above, the connection pipe 49, the U-shaped connection pipe 53, and the first, second, and third L-shaped pipes 55, 57, and 59 are appropriately rotated to connect the connection pipe 49. In the state where the position of the upper fitting portion 49A is held at a fixed position, the height position of the drain pipe 61 and the position of uneven distribution in the left and right direction with respect to the center position in the left and right direction of the frame body frame 7 can be adjusted. . Therefore, as shown in FIG. 1, when the flush toilet 1 is installed as a wall hanging type, the height position of the drain pipe 61 is adjusted between the heights H1 and H2 with respect to the position of the sewage port 33 provided on the wall 3. It is possible to easily correspond to the height position of the sewage port 33.

  In the above configuration, when the third L-shaped pipe 59 is removed from the drain trap 35 and the drain pipe 61 is connected to the connecting portion 57B of the second L-shaped pipe 57 instead of the L-shaped pipe 59, the drain pipe 61 is As shown in FIG. 9, the vertical state is obtained. Then, as described above, the connection pipe 49, the U-shaped connection pipe 53, and the first L-shaped pipe 55 are appropriately rotated horizontally to hold the upper fitting connection portion 49A of the connection pipe 49 in a fixed position. Thus, the horizontal position of the drain pipe 61 in the vertical state can be adjusted. Therefore, as shown in FIG. 5, when the flush toilet 1 is installed as a floor-standing type, the drainage pipe 61 can be easily positioned corresponding to the position of the sewage port 33 provided in the floor 47. .

  When the flush toilet 1 is installed as a floor-standing type, the first and second L-shaped pipes 55 and 57 can be integrated into an inverted U-shaped connection pipe.

  As can be understood from the above description, by adopting the drain trap 35 having the above-described configuration, even a single flush toilet 1 can be easily adapted to a wall-mounted type or a floor-mounted type. Therefore, the flush toilet 1 can be shared even when the wall-hanging type and the floor-standing type are different, and the manufacturing cost can be reduced and the productivity can be improved. Is. In the above configuration, since the connection pipe 49 is configured in a chamber having a relatively large capacity, even if there is a backflow of sewage or the like from the U-shaped connection pipe 53, the connection pipe 49 is not a buffer. It functions as. Therefore, it is possible to prevent the sewage from flowing back into the water receiving recess 15 or the storage tank 29.

  As already known in the above-mentioned patent documents and the like, when the cleaning water is circulated and reused for the cleaning water, the small water is discharged to the sewage port 33 side and the small water adhering to the water receiving recess 15 is cleaned. Things have been done. The washing water is stored in the storage tank 29 and reused. Therefore, the connection tool 19 is provided with a switching valve for switching the outflow direction of small water and washing water.

  More specifically, as shown in FIG. 10, the drainage connected to the lower end side of the pipe-shaped drainage device 17 provided in the toilet body (flush toilet) 11 is detachably connected to the connection tool 19. The fitting connection portion 19A for fitting and connecting the lower end portion to the tool 17 is provided on the upper side, and the upper end portion of the fitting connection portion 19A is supported by the protruding frame 7T in the frame body frame 7. The flange portion 19F is provided.

  The lower side of the fitting connection portion 19A is formed in a tapered portion 19T having a small diameter on the lower side, and the bottom portion of the tapered portion 19T is fitted into the upper fitting connection portion 49A of the connection pipe 49 in the drain trap 35. A connecting portion 19B to be connected is provided so as to protrude downward. A branch connection path 19D for guiding the wash water to the storage tank 29 is branched and connected to the drainage path 19C provided between the upper and lower connection portions 19A and 19B. The diameter of this branch connection path 19D is formed to be about 1/2 that of the drainage path 19C.

  A projecting wall portion 19E having a distal end projecting to a substantially central position of the drainage channel 19C is provided at a connection portion between the drainage channel 19C and the branch connection channel 19D and at an upper portion of the entrance of the branch connection channel 19D. It has been. A disc-like switching valve 65 is rotatably provided at a position corresponding to the inlet of the branch connection path 19D and in the lower position near the tip of the protruding wall portion 19E. The switching valve 65 is integrally attached to a rotating shaft 67 that is perpendicular to the protruding direction (left and right direction in FIG. 10) of the protruding wall portion 19E and horizontally penetrates the central portion of the drainage channel 19C. It is.

  The rotary shaft 67 is rotated in one direction (clockwise in FIG. 10) by an appropriate rotary actuator 69 (see FIG. 1) such as a rotary solenoid. And when the said switching valve 65 contacts the lower surface of the front-end | tip part of the said protrusion wall part 19E, and it becomes a substantially perpendicular state, it is the structure which guide | induces the small water which flowed in from the said drain tool 17 side to the said drain trap 35 side. When the switching valve 65 comes into contact with the lower edge of the inlet of the branch connection path 19D, as shown in FIG. 10, the washing that flows from the drainage device 17 side is inclined so that the branch connection path 19D side is lowered. In this configuration, water is guided to the branch connection path 19 </ b> D and flows into the storage tank 29.

  As is apparent from the above configuration, the upper portion of the inlet of the branch connection path 19D is provided with a protruding wall portion 19E whose tip protrudes to the substantially central portion of the drainage channel 19C. When guiding and discharging, the drainage channel 19C is guided and discharged to the inner peripheral surface side away from the entrance of the branch connection channel 19D. When small water is discharged, the lower part of the switching valve 65 is connected to the branch connection. Since it is arranged below the entrance of the path 19D, part of the small water does not enter the branch connection path 19D. Further, in the above configuration, the switching valve 65 rotates in the clockwise direction in FIG. 10 until the switching valve 65 contacts the lower line of the inlet of the branch connection path 19D. There is a step portion, and inflow of small water or the like to the branch connection path 19D side is suppressed.

  Therefore, the contamination rate of the washing water can be suppressed as compared with the case where a part of the small water enters the storage tank 29. Therefore, the number of times of reuse of the cleaning water can be increased, and the supply amount of the cleaning liquid from the chemical liquid tank 39 can be reduced.

  As can be understood from the above description, the connector 19, the storage tank 29, the pump 31, and the like constitute a circulation system that circulates and uses the wash water that has washed the inner surface of the water receiving recess 15. It is attached to claim 7. And as mentioned above, since the toilet bowl main body 11 provided with the said water-receiving recessed part 15 can be attached or detached with respect to the frame body claim 7, the maintenance check of the said circulation system can be performed easily.

  When the washing water is repeatedly stored and reused in the storage tank 29 as described above, slimming may adhere to the inner surface of the storage tank 29, so it is desirable to clean the inner surface of the storage tank 29. is there. Therefore, an inner surface cleaning means is provided in the storage tank 29.

  More specifically, as shown in FIG. 11, a water receiving pipe 83 for receiving a supply of new washing water from the water supply means 37 is attached to the lid member 71 detachably attached to the upper surface of the storage tank 29. . At a position close to the outlet 83A of the water receiving pipe 83, there is a rotating shaft 79 that is rotationally driven via a timing belt 77 and the like by a rotating actuator (rotary driving means) 75 such as a small motor provided at an appropriate position. The lid member 71 is vertically and rotatably provided through the lid member 71. The rotating shaft 79 is a rotating blade or the like that blows away the washing water flowing down from the outlet 83 </ b> A into the storage tank 29, and throws (drops) water droplets onto the inner surface of the storage tank 29. A rotating body 81 is attached.

  Therefore, in order to clean the inner surface of the storage tank 29, the cleaning water in the storage tank 29 is discharged to make it almost empty, and then new cleaning water is supplied from the outlet 83A of the water receiving pipe 83 into the storage tank 29. When the rotating body 75 is rotated by driving the rotating actuator 75 to flow down, the washing water flowing down from the outlet 83A is blown off vigorously by the rotating body 81, and water droplets collide with the inner surface of the storage tank 29. The Therefore, when the water droplets are brought into intense contact with the inner surface of the storage tank 29, the slime attached to the inner surface is removed and cleaned. Therefore, it is possible to prevent the generation of bad odor due to slime or the like adhering to the inner surface of the storage tank 29.

  As shown in FIG. 12, the rotary body 81 has a configuration of blades having an appropriate shape and configuration, and a configuration in which washing water is discharged (radiated) by centrifugal force generated by the rotation of the rotary body. It is also possible. In this case, the rotating body has a pipe or bowl-like configuration that is long in the radial direction, the cleaning water inflow port is provided in the upper portion on the inner end side close to the rotation shaft 79, and the discharge port is provided on the distal end side on the outer end side. A configuration is also possible. That is, various configurations can be adopted as the configuration of the rotating body 81.

  By the way, when the cleaning water in the initial state or the storage tank 29 decreases, new cleaning water is supplied from the clean water supply means 37 to the storage tank 29. At this time, since the wash water after washing the water receiving recess 15 of the toilet body 11 is stored in the storage tank 29, the storage tank can be used even when water outage or some inconvenience occurs. It is necessary to reliably prevent the cleaning water in 29 from flowing backward to the water supply means 37 side.

  Therefore, as shown in FIG. 13, in this example, the water receiving pipe 83 provided in the upper part of the storage tank 29 and the water supply nozzle 85 provided in the water supply means 37 are largely separated in the vertical direction. A sub-tank 87 having a small-diameter opening 87A at the lower end is disposed between the supply nozzle 85 and the water receiving pipe 83. The water receiving pipe 83 and the sub tank 87 are separated from each other with a space therebetween, and the supply nozzle 85 and the sub tank 87 are separated from each other through the space.

  Therefore, the clean water as the new washing water supplied from the supply nozzle 85 is temporarily held in the sub tank 87, and the water flows out from the opening 87A provided at the lower end of the sub tank 87 by its own weight. Is supplied to the water receiving pipe 83. Therefore, in the unlikely event that the washing water flows back from the storage tank 29, it may flow back into the sub tank 87 even if it flows out from the upper part of the water receiving pipe 83. There is nothing.
