And a packing 160 attached to the outlet 142 of the drainage channel 140.

  The drainage channel 140 communicates with the outlet 142 that is the downstream end thereof being inserted into the inlet 202 that is the upstream end of the drainage pipe 200 protruding from the wall W (building frame). The waste excreted into the toilet main body 120 and the washing water for washing it flow into the drainage channel 140 and guide the dirt and washing water to the drainage pipe 200. The downstream end of the outlet portion 142 of the drainage channel 140 has a rib portion 142a that protrudes outward. In addition, in this embodiment, although the exit part 142 of the drainage channel 140 is formed integrally with the toilet bowl main body 120, this invention is not limited to such a structure. For example, it is good also as a structure which attaches the drain socket separate from a toilet bowl main body to the downstream end part of a drainage channel, and uses a drain socket as the exit part of a drainage channel.

  The packing 160 will be described in detail later, but the outlet 142 of the drainage channel 140 of the toilet 100 and the drainage pipe in a state where the outlet 142 of the drainage channel 140 of the toilet 100 is inserted into the inlet 202 of the drainage pipe 200. The watertightness between the 200 inlet portions 202 is maintained.

  In addition, in this embodiment, although the exit part 142 of the drainage channel 140 of the toilet 100 is inserted in the inlet part 202 of the drainage pipe 200, in this invention, the exit part of a drainage channel is inserted in the entrance part of a drainage pipe. The sanitary equipment is not limited to a toilet bowl, and may be a urinal, a hand-washing machine, a filthy logistics, or the like. Moreover, in this embodiment, although the drainage pipe 200 protrudes from the wall W, the drainage pipe into which the exit part of the drainage channel of the sanitary equipment device in the present invention is inserted is not limited to the wall, and the floor etc. It may be protruding from. Furthermore, the drainage pipe into which the outlet part of the drainage channel of the sanitary equipment according to the present invention is inserted may not protrude from the building frame.

Fig.2 (a) is a fragmentary sectional view which shows the exit part of the drainage channel of the toilet bowl which concerns on one Embodiment of this invention, FIG.2 (b) is an enlarged view which shows the packing in (a).

  As shown in FIGS. 2A and 2B, the packing 160 has a substantially cylindrical shape as a whole. The packing 160 includes a cylindrical portion 162 that is externally fitted to the outlet portion 142 of the drainage channel 140, and a hollow annular tube portion 164 that is provided on the outer periphery of the cylindrical portion 162 and is filled with gas.

  The cylindrical part 162 has an inward hooked part 162b. When the outlet 142 of the drainage channel 140 to which the packing 160 is attached is inserted into the inlet 202 of the drainage pipe 200, the hook-shaped part 162 b is a packing 160 due to friction between the packing 160 and the inner wall of the inlet 202 of the drainage pipe 200. Is prevented from shifting from a predetermined position.

  A plurality of tube portions 164 are provided on the outer periphery of the tube portion 162 by being welded to the tube portion 162 in a state where the tube portion 164 is filled with gas. The adjacent tube portions 164 are provided in the axial direction of the cylindrical portion 162 (left and right direction in FIG. 2) with a predetermined interval d2. The predetermined interval d2 may be an interval that does not cause the tube portions 164 to crush each other when the outlet portion 142 of the drainage channel 140 is inserted into the inlet portion 202 of the drainage pipe 200. This is the same size as the diameter of the tube portion 164 in the state before the outlet portion 142 is inserted into the inlet portion 202 of the drainage pipe 200 (see FIG. 2).

  In addition, the tube portion 164 is provided such that the outer periphery thereof is positioned on the downstream side of the outer periphery of the tubular portion 162 at a predetermined distance d4 or more than the upstream end of the outlet portion 142 of the drainage channel 140. The predetermined distance d4 is such that when the outlet part 142 of the drainage channel 140 is inserted into the inlet part 202 of the drainage pipe 200 and the tube part 164 is deformed by the inner wall of the inlet part 202 of the drainage pipe 200, the tube part 164 is connected to the inlet part 202. For example, the tube portion in a state before the outlet portion 142 of the drainage channel 140 is inserted into the inlet portion 202 of the drainage pipe 200 (see FIG. 2) may be used as long as it does not protrude from the upstream end surface to the toilet 100 side. It is the same size as the diameter of 164.

  Note that the type and pressure of gas filled in the tube portion 164 are such that the tube portion 164 exhibits a sufficient sealing performance when the outlet portion 142 of the drainage channel 140 is inserted into the inlet portion 202 of the drainage pipe 200. It is selected appropriately. In the present embodiment, the tube portion 164 is formed separately from the tube portion 162, and the tube portion 164 is provided on the outer periphery of the tube portion 162 by welding the tube portion 164 filled with gas. It is not limited to such a configuration. For example, it is good also as a structure filled with gas in a tube part, after forming a tube part and a cylinder part integrally.

  Next, with reference to FIG.2 and FIG.3, the attachment of the toilet bowl 100 which is one Embodiment of this invention is demonstrated easily. FIG. 3 (a) is a partial cross-sectional view showing the outlet portion of the drainage channel in a state where the toilet according to the embodiment of the present invention is communicated with the drainage piping, and FIG. 3 (b) shows the packing in (a). It is an enlarged view shown.

  As shown in FIGS. 2A and 2B, the outlet 142 of the drainage channel 140 of the toilet 100 to which the packing 160 is attached is inserted toward the inlet 202 of the drainage pipe 200 protruding from the wall W. . At this time, the inner periphery of the cylindrical portion 162 of the packing 160 is pressed by the rib portion 142 a of the outlet portion 142 of the drainage channel 140 and is in close contact with the outer periphery of the cylindrical portion 162 and the outlet portion 142 of the drainage channel 140.

  As shown in FIGS. 3A and 3B, when the outlet 142 of the drainage channel 140 of the toilet 100 is inserted into the inlet 202 of the drainage pipe 200, a plurality of tube portions of the cylindrical portion 162 of the packing 160 are provided. 164 is deformed by the inner peripheral wall of the inlet 202 of the drainage pipe 200. At this time, the gas filled in each tube portion 164 moves from a portion that is more crushed in each tube portion 164 to a portion that is not crushed than that portion. That is, the gas filled in the tube portion 164 moves to a portion where the gap between the outlet portion 142 of the drainage channel 140 and the inlet portion 202 of the drainage pipe 200 in the tube portion 164 is large, and expands that portion. Due to the deformation of each tube portion 164 and the movement of gas in each tube portion 164, the watertightness between the outlet portion 142 of the drainage channel 140 and the inlet portion 202 of the drainage pipe 200 is maintained.

  According to the toilet 100 according to the above-described embodiment of the present invention, the axis of the outlet 142 of the drainage channel 140 of the toilet 100 is shifted from the axis of the inlet 202 of the drainage pipe 200, and in either direction. Even when it is inserted in a biased state, the gas in each tube portion 164 moves to the larger gap between the outlet portion 142 of the drainage channel 140 and the inlet portion 202 of the drainage pipe 200. Therefore, since each tube part 164 expand | swells so that the clearance gap between the exit part 142 of the drainage channel 140 of the toilet bowl 100 and the entrance part 202 of the drainage pipe 200 may be filled, it does not take time for construction, and drainage pipe 200 and large Watertightness with the toilet bowl 200 can be maintained.

  Further, according to the toilet 100 according to the embodiment of the present invention described above, the outer periphery of the tube portion 164 is more downstream than the upstream end of the outlet portion 142 of the drainage channel 140 by a predetermined distance d4 or more on the outer periphery of the tube portion 162. Located in. Therefore, when the outlet part 142 of the drainage channel 140 of the toilet 100 is inserted into the inlet part 202 of the drainage pipe 200, the deformed and crushed tube part 164 moves from the inlet part 202 of the drainage pipe 200 to the toilet 100 side. It is prevented from protruding and being visible to the user.

  Furthermore, according to the toilet 100 according to the embodiment of the present invention described above, since a plurality of tube portions 164 are provided, the sealing performance is further increased as compared with the case where a single tube portion 164 is provided, so that water leakage is more reliably ensured. Can be prevented. Moreover, since each tube part 164 is spaced apart at a predetermined interval d2, when the outlet part 142 of the drainage channel 140 of the toilet 100 is inserted into the inlet part 202 of the drainage pipe 200, each tube part 164 is crushed and deformed. In addition, the tube portions 164 are prevented from interfering with each other. Accordingly, it is possible to suppress the deformation of the tube portions 164 due to the interference between the tube portions 164 and the deterioration of the sealing performance.
