Description

  The present invention relates to a water passing device for eliminating clogging generated in a drain pipe of a flush toilet or the like.

  Conventionally, when foreign matter is clogged in the drain pipe of a flush toilet such as a Japanese-style toilet or a Western-style toilet, a water flow cup (water flow tool) is known as a tool used to eliminate this clogging. . The water-flowing cup is generally composed of a handle for a user to hold and a dome-shaped cup member. The cup member is made of an elastic material and has an annular tip portion that forms an opening facing the tip of the handle. In order to eliminate the clogging of the drain pipe in the water-flowing cup, first, the cup member is pressed by pressing the annular tip of the cup member around the toilet outlet, and then pushing and pulling the handle. Is elastically deformed. Here, a positive pressure and a negative pressure are generated in the drain port due to elastic deformation of the cup member, and this pressure acts in the drain pipe through the drain port. The clogging is eliminated.

  Patent Document 1 includes, as a cup member, a tapered cylindrical portion provided at the tip of a dome-shaped portion, and a ring-shaped ridge extending outward from between the dome-shaped portion and the cylindrical portion. A structured water cup is disclosed. The extending width of the ring-shaped ridge is uniform over the entire circumference. According to the water-flowing cup having such a configuration, it is expected that the adhesion to the inner wall surface around the drainage port is expected even in a Western-style toilet, even when the drainage port size is relatively large.

  In recent years, efforts have been made to reduce the amount of water used during running water and to increase the cleaning power of toilet walls during running water in flush-type western toilets. Toilet bowls with wall surfaces have been developed. When the water flow cup disclosed in Patent Document 1 was used for such a toilet, it was possible that sufficient adhesion could not be obtained.

  Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the drawings.

  1 to 3 show an example of a water passing device according to the present invention. The water flow tool A1 of the present embodiment includes a handle 1 having a longitudinal axis, and a pressure member 2 attached to the tip of the handle 1.

  The handle 1 is made of, for example, a synthetic resin or a lightweight metal and has a solid or hollow rod shape. As shown in FIG. 3, a male screw 1 a for attaching the pressing member 2 is formed at the tip of the handle 1.

  As shown in FIGS. 1 to 3, the pressing member 2 includes a main body 21 and a flange 23 connected to the main body 21. The pressure member 2 is integrally formed of a rubber material such as natural rubber or a soft synthetic resin material, and can be elastically deformed.

  The main body 21 has a proximal end portion 211, an intermediate portion 212, and an annular distal end portion 213. The base end portion 211 is a portion connected to the handle 1 and has a cylindrical shape in which a female screw 211a is formed on the inner periphery. The female screw 211a can be screwed with the male screw 1a of the handle 1. The pressure member 2 is attached to the handle 1 by screwing the male screw 1a of the handle 1 into the female screw 211a. The intermediate portion 212 connects the proximal end portion 211 and the annular distal end portion 213, and has a dome shape in this embodiment. The annular tip 213 has a circular shape, and an opening 214 facing the tip of the handle 1 is formed by a region surrounded by the annular tip 213. In the present embodiment, the annular tip 213 is provided with a bulging portion 215 that bulges on the entire inner circumference side. The width dimension w1 of the bulging portion 215 is approximately the same as the thickness t1 of the annular tip portion 213. As an example of the dimensions of the annular tip 213, the thickness t1 is about 4 to 5 mm and the outer diameter dimension d1 is about 150 mm.

  The flange 23 extends to the outer periphery of the annular tip 213, and in this embodiment, a small annular part 231 connected to the outside of the annular distal part 213 and an overhanging part 232 projecting outside the small annular part 231 are provided. It is prepared for. The small annular portion 231 is provided on the entire circumference of the annular distal end portion 213, but the extension width w2 from the outer periphery of the annular distal end portion 213 is, for example, about 8 mm (1/20 of the outer diameter dimension d1 of the annular distal end portion 213). Grade). Further, the thickness of the small annular portion 231 decreases with increasing distance from the annular distal end portion 213. The lower surface 231a of the small annular portion 231 follows the radial direction of the annular distal end portion 213, while the upper surface 231b extends with respect to the radial direction. Is inclined.

  The overhang portion 232 has a plate shape with a uniform thickness, and is partially provided in a predetermined range in the circumferential direction of the annular tip portion 213. In the present embodiment, the overhang portion 232 is provided on one side of the range of a substantially half circumference of the annular tip portion 213 and extends along the radial direction of the annular tip portion 213. A thickness t2 of the overhang portion 232 is, for example, about 2 mm.

  The overhang portion 232 includes a maximum extension width portion 233 and an extension width changing portion 234 located on both sides of the maximum extension width portion 233. The maximum extension width portion 233 is a portion having the maximum extension width from the outer periphery of the annular tip portion 213, and the extension width w3 of the maximum extension width portion 233 (in this embodiment, the outer periphery of the annular tip portion 213). To the tip of the maximum extension width portion 233 including the small annular portion 231) is preferably 1/6 to 1/2 of the outer diameter d1 of the annular tip portion 213, for example, about 43 mm. .

  The extension width changing portion 234 is a portion where the extension width from the outer periphery of the annular tip portion 213 changes in the circumferential direction of the annular tip portion 213, and the extension width decreases as the distance from the maximum extension width portion 233 increases. Yes.

  Next, a method of using the water passing tool A1 having the above configuration will be described. 4 and 5 show an example of a toilet bowl that is a target of use of the water flow tool A1. The toilet P1 shown in the figure is a so-called water-saving toilet, and the dimension in the front-rear direction (vertical direction in FIG. 4) is larger than the dimension in the left-right direction. The inner wall surface 40 of the toilet bowl P1 has a special shape with irregularities, and has an asymmetric shape. More specifically, a convex portion 41 is formed on the front left side of the drainage port 43, and the right side of the convex portion 41 is a concave portion 42. The drain pipe 44 of the toilet bowl P1 is clogged with foreign matter O1.

  When using the water flow tool A1, as shown in FIGS. 6 and 7, the annular tip 213 of the water flow tool A1 is brought into close contact with the inner wall surface around the drain port 43. Here, as shown in FIG. 6, the overhanging portion 232 of the flange 23 is directed to the front side so that the overhanging portion 232 overlaps the convex portion 41 and the concave portion 42. Next, the pressure member 2 is elastically deformed by pushing and pulling the handle 1. Here, positive pressure and negative pressure are generated in the drain outlet 43 due to elastic deformation of the pressurizing member 2, and this pressure acts in the drain pipe 44 through the drain outlet 43. This pressure causes clogging. The foreign matter O1 is moved in the upstream or downstream direction, and the clogging is eliminated.

  The water flow tool A1 of the present embodiment includes a ridge 23 having an extended width changing portion 234, and has a maximum extended width portion 233 that is connected to the extended width changing portion 234 and has the maximum extended width. . For this reason, the convex part 41 and the concave part 42 can be appropriately closed by directing the overhang part 232 including the maximum extension width part 233 toward the front side of the toilet bowl P1. Here, as shown in FIG. 7, the annular tip 213 is not in close contact with the recess 42, but it is possible to close the recess 42 with the overhang 232. Thereby, the sealing performance of the drain outlet 43 by the pressurizing member 2 is maintained at the time of use of the water flow tool A1.

  The flange 23 has a maximum extending width portion 233 and an extending width changing portion 234 connected thereto. For this reason, the flange 23 does not have a uniform extension width in the circumferential direction of the annular tip portion 213, and the overhang portion 232 (the maximum extension width portion 233 and the extension width changing portion 234 connected thereto) has the annular tip portion 213. In the circumferential direction. Since the dimension of the toilet P1 in the left-right direction is relatively small, the annular tip 213 can be brought into close contact with the left and right sides of the inner wall surface 40 of the toilet P1 by arranging the overhanging portion 232 so as not to face the left-right direction. it can.

  Unlike the present embodiment, for example, as shown in FIG. 8, a flange 33 having a relatively wide extension from the annular tip 213 and a uniform extension over the entire circumference is provided. In the case where the inner wall surface 40 is on the left and right sides, there is no escape space for the flange 33, so that the flange 33 is easily deformed. Due to the deformation of the flange 33, the annular tip 213 is also deformed, and a gap is easily generated between the annular tip 213 and the inner wall surface 40. As a result, the sealing performance of the drain port 43 is lowered.

  FIG. 9 shows another example of a toilet bowl to be used for the water flow tool A1. The toilet P2 shown in the figure is a so-called water-saving type toilet, and a water outlet 52 is provided in the middle of the inner wall surface 50 in addition to the water outlet 51 at the top. As shown in FIGS. 10 and 11, the inner wall surface 50 has a special shape having a step, and a water outlet 52 is provided in the step portion. The drain pipe 54 of the toilet P2 is clogged with foreign matter O2.

  When the water flow tool A1 is used, the annular tip 213 of the water flow tool A1 is brought into close contact with the inner wall surface around the drain port 53. Here, the water flow tool A <b> 1 is in a posture in which the overhang portion 232 of the eaves 23 overlaps the water outlet 52. Next, the pressure member 2 is elastically deformed by pushing and pulling the handle 1. Here, positive pressure and negative pressure are generated in the drainage port 53 due to elastic deformation of the pressurizing member 2, and this pressure acts in the drainage pipe 54 through the drainage port 53, and this pressure causes clogging. The foreign matter O2 present moves in the upstream or downstream direction, and the clogging is eliminated.

  The water flow tool A1 of the present embodiment includes a ridge 23 having an extended width changing portion 234, and has a maximum extended width portion 233 that is connected to the extended width changing portion 234 and has the maximum extended width. . For this reason, the water outlet 52 can be appropriately closed by overlapping the protruding portion 232 including the maximum extending width portion 233 on the water outlet 52. Thereby, at the time of use of the water flow tool A1, it is avoided that air leaks through the water outlet 52, and the sealing performance of the water outlet 53 by the pressurizing member 2 is maintained.

  The flange 23 has a maximum extending width portion 233 and an extending width changing portion 234 connected thereto. For this reason, the flange 23 does not have a uniform extension width in the circumferential direction of the annular tip portion 213, and the overhang portion 232 (the maximum extension width portion 233 and the extension width changing portion 234 connected thereto) has the annular tip portion 213. In the circumferential direction. Since the dimension of the toilet P2 in the left-right direction is relatively small, the annular tip 213 can be brought into close contact with the left and right sides of the inner wall surface 50 of the toilet P2 by arranging the overhanging portion 232 so as not to face in the left-right direction. it can.

  In addition, although detailed illustration description is abbreviate | omitted, the water flow implement A1 of this embodiment can be used also for western style toilets and Japanese style toilets other than the above-mentioned water-saving toilet. Since the maximum extension width part 233 is partially provided, by selecting the direction of the maximum extension width part 233, the extension part 232 including the maximum extension width part 233 can be attached to the inner wall surface of the toilet. It is possible to avoid obstructing the adhesion.
