  That is, the drainage pipe 300 includes a rising portion 302a that rises up to a predetermined height with respect to the toilet body 100 in the pipe portion 302 described above. By providing the rising portion 302a, when water is supplied, water is accumulated in the toilet body 100 and the drain pipe 300 up to the height h1 of the bottom 302a1 of the uppermost pipe line of the rising portion 302a (see FIG. 10). The toilet body 100 and the drain pipe 300 have a required capacity up to the height h1. The capacity secured up to the height h1 may be determined in consideration of the general amount of human defecation or urination, and the height h1 may be determined in consideration of the capacity.

  In the internal space 210, an intermediate part of the pipe line part 302 including the rising part 302a is piped. In this embodiment, as shown in FIGS. 2, 3, 9 and 10, the pipe section 302 of the drain pipe 300 has a first bent section 321, a first pipe section 322, and a second folded section. A bent portion 323, a second tube portion 324, an inner tube portion 325, a third tube portion 326, a third bent portion 327, and an outer tube portion 328 are provided.

  The first connection part 301 is connected to the first bent part 321. In the 1st bending part 321, the pipe line is bent sideways. The first pipe portion 322 connected to the first bent portion 321 extends in the horizontal direction and is connected to the second bent portion 323. In the second bent part 323, the pipe is bent upward. The second pipe portion 324 connected to the second bent portion 323 extends upward toward the internal space 210 between the outer frame 200 and the toilet body 100 through the opening 203 of the outer frame 200. An internal tube portion 325 extends in the internal space 210.

In FIG. 9, a two-dot chain line D <b> 1 indicates a general outline of the bottom 101 of the toilet main body 100 at the height of the second pipe 334 of the inner pipe 325 in a state where it is attached to the toilet main body 100. . The inner pipe portion 325 is disposed around the bottom 101 of the toilet main body 100 as shown in FIG.

  As shown in FIG. 9, the first bent portion 331 is provided at the upper end of the second pipe portion 324. In this embodiment, in the 1st bending part 331, while a pipe line is bent horizontally, it is directed ahead. The first conduit 332 extends forward from the first bent portion 331. In relation to the toilet main body 100, the first pipe line 332 extends rightward and forward on the right side of the bottom 101 of the toilet main body 100. The second bent portion 333 is provided at the tip of the first pipe line 332. In the second bent portion 333, as shown in FIG. 9, the pipe line is bent 90 degrees to the left. The second conduit 334 connected to the second bent portion 333 extends laterally from the right side to the left side in front of the bottom 101 of the toilet body 100. A third bent portion 335 is provided at the tip of the second pipe 334.

  In the third bent portion 335, the pipe line is bent backward. The 3rd pipe line 336 connected to the 3rd bending part 335 is extended from the front to the back in the left side of the bottom part 101 of the toilet bowl main body 100, as shown in FIG. A fourth bent portion 337 is provided at the rear end of the third conduit 336. In the 4th bending part 337, the pipe line is bent below. The third pipe portion 326 described above is connected to the fourth bent portion 337. The third pipe portion 326 protrudes from the inner space 210 to the outside of the outer frame 200 through the opening 267. A third bent portion 327 is provided at the lower end of the third tube portion 326. In the third bent portion 327, the pipe line is bent backward and connected to the external pipe portion 328.

  Thus, the pipe line part 302 of the drainage pipe line 300 includes a plurality of bent parts. In this embodiment, as shown in FIGS. 3, 9, and 10, a first bent portion 321, a second bent portion 323, and a third bent portion 327 are provided. Further, the pipe line part 302 includes a plurality of bent parts 331, 333, 335, and 337 in the internal pipe part 325. In such a bent portion, eddy currents are easily generated and feces are easily crushed, so that sewage containing feces can flow smoothly by negative pressure suction. In this embodiment, a general-purpose pipe having a pipeline bent at approximately 90 degrees is used for the above-described bent portion. In particular, the pipe line bent at 90 degrees is likely to generate vortex, stool is easily crushed, and sewage containing stool can be smoothly flowed by negative pressure suction.

  In this embodiment, the pipe line is bent at 90 degrees at the bent portion. This is only one preferred form of the bend. The bent portion may be a portion that bends the pipe line at an angle of approximately 30 degrees or more, and the bending angle is not necessarily limited to 90 degrees. Here, the angle of the bent portion means an angle at which the center line of the straight pipe line connected to the bent portion intersects. Then, based on the virtual line obtained by extending the center line of the pipe line on one straight line connected to the bent part, the center line of the other pipe line connected to the bent part extends along the virtual line. This means the angle at which the other pipe line intersects the virtual line.

  In this embodiment, the outer frame 200 of the simple toilet 10 includes a stationary part 201 on which the toilet body 100 is detachably installed, a peripheral wall part 202 that surrounds the outside of the toilet body 100 that is stationary on the stationary part 201, and a peripheral wall part 202. , And an opening 203 that exposes the bottom 101 of the toilet body 100. An inner wall 204 is provided around the opening 203.

  For example, according to the simple toilet 10, as shown in FIG. 3, the outer frame 200 has the tray 222 disposed on the upper member 240, and the toilet body 100 is placed on the tray 222. Here, there are gaps between the toilet body 100 and the tray 222 and between the tray 222 and the upper member 240. For this reason, when a user uses, there is room for urine to enter from these gaps. The urine that enters enters the bottom of the upper member 240. In the simple toilet 10, an inner wall 204 is provided in the opening 203 of the outer frame 200. For this reason, even when urine enters the bottom of the upper member 240, it is difficult to leak into the floor.

  In this embodiment, the opening 203 of the outer frame 200 has a size that allows the drainage pipe 300 to be pulled up to the inside of the outer frame 200 when the toilet body 100 is removed from the outer frame 200. FIG. 11 is a left side view illustrating a process of removing the toilet body 100 from the outer frame 200. The toilet body 100 is a cross-sectional view in FIG. 3, but the appearance of the toilet body 100 is illustrated in FIG. 11. In addition, in FIG. 11, illustration of the water supply pipe connected to the nozzle 120 (see FIG. 3) is omitted.

  When removing the toilet body 100 from the outer frame 200, the external pipe 401 and the metal fitting 340 are removed from the drain pipe 300 as shown in FIG. 11. Then, the drain pipe 300 is pulled up from the opening 203 of the outer frame 200 while the toilet body 100 placed on the tray 222 is pulled upward. In this embodiment, since the drain pipe 300 has the outer pipe portion 328 extending rearward, the drain pipe 300 can be pulled up through the opening 203 by tilting the front side of the toilet body 100 upward. Thus, the opening 203 of the outer frame 200 has a size that allows the drainage pipe 300 to be pulled up to the inside of the outer frame 200 when the toilet main body 100 is removed from the outer frame 200. For this reason, the toilet body 100 can be removed from the outer frame 200 in a state where the drain pipe 300 is attached to the toilet body 100. When removing the toilet body 100, an appropriate cap (not shown) may be attached to the second connection portion 303 in order to prevent the sewage remaining in the drainage pipe 300 from dripping.

  In this embodiment, the intermediate part of the pipe line part 302 of the drainage pipe line 300 enters the internal space 210 between the outer frame 200 and the toilet body 100 through the opening 203 as shown in FIG. Then, it extends to a predetermined height h <b> 1 at an intermediate position of the toilet body 100, and comes out of the outer frame 200 through the opening 203. Thus, the rising portion 302 a extending to the predetermined height h 1 is provided in the internal space 210 through the opening 203. Further, the pipe line portion 302 of the drainage pipe line 300 extends to a predetermined height h <b> 1 at an intermediate position of the toilet body 100. For this reason, a predetermined amount of water is stored in the toilet body 100. Further, an intermediate part of the pipe line part 302 of the drainage pipe line 300 is arranged in the internal space 210 through the opening 203. The opening 203 may be formed widely according to the configuration of the pipe line portion 302. Since the intermediate part of the pipe line part 302 including the rising part 302a is formed in the internal space 210 through the opening 203, when the toilet body 100 is pulled up, there are few pipe lines that pass through the opening 203 in the drainage pipe line 300. Become. For this reason, the opening 203 can be made small.

  Furthermore, the pipe line part 302 is preferably provided with a plurality of bent parts. Furthermore, it is preferable that the inner pipe portion 325 disposed in the inner space 210 is also provided with a plurality of bent portions. Thus, since the some bending part is provided, the stool in sewage is grind | pulverized to a suitable magnitude | size in the case of negative pressure suction. For this reason, the sewage containing feces can flow smoothly. Further, the inner tube portion 325 including a plurality of bent portions is provided on the inner side of the opening 203 of the outer frame 200. The internal pipe portion 325 does not interfere with the operation when the toilet body 100 is installed or removed. For this reason, workability at the time of deferring or removing the toilet body 100 is good.

  In addition, about the drainage pipe line 300, the specific piping structure is not limited to embodiment mentioned above. In particular, in consideration of workability when the toilet body 100 is installed or removed, an intermediate portion of the pipe section 302 of the drain pipe 300 is disposed in the inner space 210 of the outer frame 200 through the opening 203. An intermediate part of the pipe line part 302 that has a plurality of bent parts and is bulky as piping is inside the outer frame 200. For this reason, when pulling up the toilet main body 100 with the drain pipe 300 connected, the pipe section 302 is unlikely to get in the way. From the same viewpoint, it is desirable that the intermediate part of the pipe line part 302 disposed in the internal space 210 through the opening 203 is disposed in the vicinity of the toilet body 100 as shown in FIG.

  Further, as described above, the shape of the opening 203 of the outer frame 200 is such that at least three pipe parts can be accommodated around the first connection part 301 to the extent that the drain pipe 300 is inserted vertically. It is preferable to have a width. In view of ease of processing, it is preferably substantially circular. Specifically, the diameter is, for example, 70 mm or more, more preferably 100 mm or more, and for example, 300 mm or less, more preferably 200 mm or less.

  The embodiment of the simple toilet 10 proposed here has been described above. The simple toilet according to the present invention is not limited to the simple toilet 10 unless otherwise specified. Hereinafter, modifications of the simple toilet 10 will be described.

  For example, in the above-described embodiment, the nozzle 120 as a cleaning nozzle is attached to the inner peripheral surface of the toilet body 100 (see FIG. 3). The cleaning nozzle 120 is not necessarily provided on the inner peripheral surface of the toilet body 100. Although illustration is omitted, a pipe for supplying the cleaning liquid to the toilet body 100 may be disposed on the upper portion of the toilet body 100. Moreover, it is preferable that the negative pressure suction toilet described above is configured to be poured into the toilet body 100. For example, water may be poured into the toilet body 100 from the washing nozzle as described above. In addition, a user or an assistant may prepare water in the vicinity of the simple toilet 10 with a plastic bottle or the like in advance and supply it to the toilet body 100 as appropriate. Moreover, the nozzle which ejects washing water toward a user's anus or a genital area may be provided. Such a nozzle may be movable so as to advance to an appropriate position of the toilet body 100.

  In the embodiment described above, the outer frame 200 of the simple toilet 10 includes the peripheral wall 202 that surrounds the outside of the toilet body 100 and the opening 203 that exposes the bottom of the toilet body 100. In the embodiment described above, the peripheral wall portion 202 of the outer frame 200 covers the side of the toilet body 100 when the simple toilet 10 is viewed from the side. Thus, since the peripheral wall part 202 of the outer frame 200 covers the side of the toilet body 100, the toilet body 100 can be concealed in appearance, and the design of the toilet body 100 is improved. Further, since the peripheral wall portion 202 of the outer frame 200 covers the side of the toilet body 100, it is possible to reduce the sound generated in the toilet body 100 such as a sound during urination from being echoed to the side. In the above-described embodiment, the outer frame 200 has a structure in which the upper member 240 and the lower member 260 are combined vertically. In such a structure, since the peripheral wall portion 202 of the outer frame 200 has a double structure of the side surface of the upper member 240 and the side surface of the lower member 260, the sound generated in the toilet main body 100 is less affected from the side. High effect. The bottom of the toilet main body 100 is exposed, and the maintenance of the drainage pipe connected to the outlet provided in the bottom of the toilet main body 100 is facilitated.

  In the above-described embodiment, the peripheral wall 202 covers the side of the toilet body 100 on the entire circumference, but the peripheral wall 202 does not cover the side of the toilet body 100 in a part of the circumferential direction. There may be a site. In the embodiment illustrated in FIG. 3, the outer frame 200 has a structure in which an upper member 240 and a lower member 260 are vertically combined, but the outer frame 200 is not limited to such a structure.

  Further, considering the general amount of defecation of the user, the toilet body 100 needs to have a required depth and capacity. In addition, it is desirable that the peripheral wall 202 covers the side of the toilet body 100 from the viewpoint of reducing the sound reverberating to the side of the toilet body 100 as described above. From this viewpoint, the peripheral wall 202 of the outer frame 200 may extend downward from the peripheral wall 202 with respect to the bottom 101 of the toilet body 100, and the opening 203 may be provided at a low position. However, it is not necessary to extend the peripheral wall portion 202 excessively downward with respect to the bottom portion 101 of the toilet body 100. If the peripheral wall 202 of the outer frame 200 is excessively extended downward with respect to the bottom 101 of the toilet body 100, it is not appropriate in terms of weight increase and material cost.

  For this reason, from the viewpoint of improving the design of the toilet body 100 and reducing the sound reverberating to the side of the toilet body 100, for example, as shown in FIG. The opening 203 of the outer frame 200 may be approximately the same height. The height h2 of the opening 203 of the outer frame 200 is, for example, the bottom surface of the outer frame 200 provided with the opening 203 of the outer frame 200 (the height of the bottom 261 of the lower member 260 in the form of FIG. 3). FIG. 10 shows the height h2 of the opening 203 of the outer frame 200 with respect to the bottom 101 of the toilet main body 100 in the form shown in FIG.

  Further, the toilet body 100 may take measures to reduce the sound generated in the toilet body 100, such as winding a soundproof material around the outer peripheral surface. In this case, the peripheral wall 202 of the outer frame 200 may not completely cover the side of the toilet main body 100 from the viewpoint of reducing the sound reverberating to the side of the toilet main body 100. Further, the bottom 101 of the toilet body 100 is a position that cannot be seen from above, and is difficult to see when the user normally uses it. For this reason, the height h2 of the opening 203 of the outer frame 200 may be provided slightly above (for example, about 3 cm above) the bottom 101 of the toilet body 100. The simple toilet 10 proposed here is not limited to the form shown in FIG. 3, and the peripheral wall 202 of the outer frame 200 may generally surround the outside of the toilet body 100, and There is no need to completely enclose the sides. The height h2 of the opening 203 of the outer frame 200 is set to be lower than the bottom 101 of the toilet body 100, and the peripheral wall 202 of the outer frame 200 completely surrounds the outer side of the toilet body 100. Also good.

  Further, in the above-described embodiment, as shown in FIG. 3, as an inner wall 204 provided in the opening 203 of the outer frame 200, a tube material 248 with a flange 248 a that is separately molded from resin is formed in the opening 247 of the upper member 240. It is attached. The inner wall 204 is not limited to such a form. FIGS. 12 to 14 are schematic views illustrating other forms of the method for processing the inner wall 204 provided in the opening 203 of the outer frame 200. For example, as shown in FIG. 12, the outer frame 200 may be an integrally molded product in which an inner wall 204 rises inside the periphery of the opening 203. Productivity is good because molding can be done in one shot. However, this method may increase the processing cost of the mold, and may make it difficult to remove the molded product from the mold (die removal) because the inner wall 204 bites into the mold.

  As another method, for example, as shown in FIG. 13, the outer frame 200 is formed of a thermoplastic resin, and a hole 203 a having a required size is opened at the bottom of the outer frame 200. The hole 203a may be formed in the bottom of the flat outer frame 200 with a drill after forming. Moreover, you may form a hole in the bottom part of the flat outer frame 200 at the time of metal mold | die shaping | molding. Then, as shown in FIG. 14, the mold 600 having the substantially hemispherical projection 602 is heated in the hole and is pulled out from below the hole 203 a. Thereby, the edge 203a1 of the hole 203a may be deformed along the mold 600 to form the inner wall 204 rising upward. As described above, various methods can be employed for forming the inner wall 204 of the opening 203 of the outer frame 200.

  As described above, various modifications of the simple toilet proposed here have been described. The simple toilet 10 proposed here is not limited to such a modified example unless specifically mentioned.

  The present invention can be used industrially as a simple toilet.
