According to the first aspect of the present invention, there is provided a sealed trap having a fixed end fixed to a drain pipe extending from a bowl, and a free end that is rotatable in the vertical direction by transmitting a rotational force from a driving source. In the disposed toilet drainage device, the sealing trap is housed in a case main body portion having a substantially rectangular base portion where a drainage portion is formed below, and the base portion of the case main body portion is placed on the floor surface. A convex portion serving as a positioning guide for fixing the case main body to the drainage adjuster is fixed on a substantially rectangular flange-shaped receiving portion formed with a drain outlet of a drainage adjuster provided. And a recess projecting in the vertical direction at the four corners of one outer edge of the receiving portion of the drainage adjuster, and a recess contacting the projection is a base of the case body and the receiving portion of the drainage adjuster. Provided at four corners of the other edge of the convex portion is characterized in that it comprises a curved surface which is guided inserted along the recess.

According to the invention of claim 1, the base portion of the case main body is fixed on the substantially rectangular flange-shaped receiving portion in which the drainage port of the drainage adjuster provided on the floor surface is formed . Protrusions as positioning guides when fixing the case main body to the drainage adjuster are provided so as to protrude vertically in the four corners of one outer edge of the base of the case main body and the receiving part of the drainage adjuster, and the convex portion and the abutting recesses Ru provided at four corners of the other edge of the base and the drain adjuster receiving portion of the case body. Moreover, the said convex part is provided with the curved surface inserted and guided along the said recessed part.

Therefore, the concave portion and the convex portion, positioned so gradually inserted with the guide to a predetermined position of the case body in the drainage adjuster can be reliably and easily. And since a packing is not damaged, a sealing performance is securable.

  Embodiments of the present invention will be described below with reference to the drawings.

<Configuration of toilet drainage device>
As shown in FIG. 1, a toilet drainage device 31 according to an embodiment of the present invention includes a fixed end 35 a fixed to a drain pipe 34 extending from a bowl 33 of a toilet 32, and rotation from a drive source such as a motor (not shown). A sealing trap 35 having a free end portion 35b which is transmitted with force and is rotatable in the vertical direction as indicated by an arrow Q is disposed.

  The sealing trap 35 is housed in a case main body 36 having a drainage portion 36a below, and the upper portion of the case main body 36 serves as a lid 49 that can be opened via the flange 50 so as to be convenient for maintenance and the like. Yes.

  The case main body 36 is fixed to a drainage adjuster 38 provided on the floor surface 37, and a concave portion 57 is provided at four corners of the drainage adjuster 38 and a convex portion 52 is provided on the case main body 36 of the sealing trap 35. The drainage adjuster 38 and the sealing trap 35 can be easily aligned by the concave portion 57 and the convex portion 52. The drainage adjuster 38 is fixed to a floor flange connecting portion 42 connected to the external drainage pipe 41 through a horizontal pulling pipe 43.

  Here, a storage space portion 32a is provided inside the rear portion of the toilet bowl 32, and the case main body portion 36 is stored in the storage space portion 32a. A water supply means 40 for supplying water to the bowl 33 is disposed on the rear upper surface of the toilet bowl 32, and is connected to a water pipe via a water supply electromagnetic valve (not shown).

  A mounting hole 44 substantially equal to the outer diameter of the water sealing trap 35 is provided on one side wall 36b of the case main body 36, and the water sealing trap 35 that can be rotated and turned upside down is inserted into and attached to the mounting hole 44. Further, the fixed end 35a of the sealing trap 35 protrudes from the case main body 36 and is externally fitted to a bowl drain port 33a formed at the rear end of the bowl 33, and the outer periphery of the fixed end 35a is hose band or the like. It is fixed by tightening.

  The sealed water trap 35 is a soft material such as resin or rubber, and is a bellows-like hose that can be expanded and contracted. The majority of the sealed water trap 35 is disposed in the case main body 36.

  A support member 45 is fixed to the free end 35 b of the sealing trap 35, and the support member 45 has a rotating shaft 47 extending outside the sealing trap 35 passing through the shaft hole 47 a of the case body 36. The motor is connected to a motor through a reduction gear, clutch means, etc. (not shown).

"Operation of toilet drainage"
Since the free end portion 35b of the sealed water trap 35 is normally disposed facing upward, the inside of the bowl 33 is in a sealed state with water stored at a height up to the free end portion 35b. When toilet flushing is input after the toilet, flush water is supplied to the bowl 33.

  At this time, for example, after 2 to 3 seconds, the motor operates in the forward direction, the free end 35b rotates downward, the motor stops at a position facing the drain hole 55b of the receiving portion 55, and the filth is collected together with the accumulated water. Discharged.

  When the filth is completely discharged, the motor rotates in the reverse direction, the free end portion 35b of the sealing trap 35 rotates upward, the water is stored inside, and the sealed state is restored.

  As shown in FIGS. 2, 3, and 4, convex portions as positioning guides when fixing to the drainage adjuster 38 at the four corner lower portions 51 a of the substantially rectangular base portion 51 that forms the drainage portion 36 a of the case body 36. 52 is provided.

  Since the convex portion 52 has an egg-shaped (three-dimensional shape) curved surface, the curved surface of the convex portion 52 can be three-dimensionally guided and inserted along the concave portion 57, so that the case main body 36 is moved downward. Then, the drainage adjuster 38 can be inserted into a predetermined position while being guided gradually and continuously from the four corners.

  Now, the egg-shaped curved surface of the convex portion 52 is formed in an area of S = approximately 15 mm in the X and Y directions on the plane and an area of H = approximately 20 mm in the height Z direction. Thus, since positioning can be performed reliably and easily, the base 51 (case body 36) can be aligned with the drainage adjuster 38 in a pinpoint manner.

  Bolt holes 53 a into which bolts 53 for fixing to the drainage adjuster 38 are inserted are formed at the center of the pair of opposing sides of the base 51. In this embodiment, only the pair of central bolt holes 53a is actually used, but two pairs of spare holes 53b are prepared on both sides thereof, and the actual bolt holes cannot be formed in the spare holes 53b. The bolt hole can be easily opened at the time of use. Around the drainage part 36a in the central part of the base 51, there is provided a region 61 where a packing provided on a receiving part 55 of a drainage adjuster 38, which will be described later, abuts.

  A base 54 extends downward from the base 51. This is provided so that the drain adjuster 38 is not used and the case main body 36 can be installed directly on the floor 37. Yes, not used in this example.

  The drainage adjuster 38 includes a receiving portion 55 having a substantially rectangular flange shape, a base 56 fixed to the floor, and a drainage portion 65 sandwiched between the receiving portion 55 and the base 56. The central portion of the receiving portion 55 is provided with a drain hole 55b and an insertion port 65b for inserting the horizontal draw pipe 43 into one side surface 65a of the drainage portion 65. The direction of drainage can be changed by 90 degrees.

  The four corner portions 55a of the receiving portion 55 are formed with substantially planar concave portions 57 that contact the convex portions 52 in order to guide the base portion 51 of the case main body portion 36 to a predetermined position. The central portion surrounds the drain hole 55b. A packing groove 58 into which a packing (not shown) is inserted is provided.

  Three U-shaped nut insertion portions 59 for holding nuts (not shown) for screwing with the bolts 53 are formed on opposite sides 55 c of the receiving portion 55. In the embodiment, only the pair of nut insertion portions 59 at the center are actually used corresponding to the bolt holes 53a at the center of the pair of sides of the base 51.

<Operation of toilet drainage device>
As described above, the convex portions 52 at the four corners having the egg-shaped (three-dimensional shape) curved surface are guided while being continuously lowered along the concave portion of the drainage adjuster 38 by the egg-shaped gradient. The case main body 36 (base 51) can be pinpointed to the drainage adjuster 38 because it can be accurately inserted to the position.

  Since the case main body 36 (base 51) can be pinpointed to the drainage adjuster 38, the packing in the packing groove 58 is not damaged, and the packing is pressed against the region 61 to provide a reliable seal (water sealing). Sex can be obtained.

  In addition, when the egg shape (three-dimensional shape) of the convex part 52 has a gradient more than a predetermined due to a manufacturing error, the convex part 52 stops in the middle of descending along the concave part of the drainage adjuster 38 and the toilet 32 itself. Cannot descend to floor 37. For this reason, since it can be easily determined that the convex portion 52 needs to be readjusted, it is possible to prevent the toilet 32 from being installed at a defective position. As a result, reliable construction can be carried out.

  As mentioned above, although embodiment of this invention was described based on drawing, all said Example shows an example of this invention, and it cannot be overemphasized that this invention should not be limited to these. For example, instead of providing the concave portion 57 on the drainage adjuster 38 and the convex portion 52 on the case main body portion 36 of the sealing trap 35, it is possible to provide a convex portion on the drainage adjuster and a concave portion on the case main body portion of the sealing trap.
