Abstract

<P>PROBLEM TO BE SOLVED: To provide a toilet bowl device in which a trap is prevented from being clogged with a solid matter. <P>SOLUTION: A drain hole 20 is formed at the lower part of the bowl 14 of a toilet bowl device 11. The drain hole 20 is connected to a short pipe 21 in the horizontal state. When the bowl 14 is flushed with a flushing water P after evacuation, a solid matter K is carried by the flushing water P and drained from the drain hole 20. Though a flow passage starting at the bowl 14 to the short pipe 21 is connected in a generally streamlined shape to minimize the in-line resistance for smoothly flowing the solid matter, the peripheral edge 20a of the area surrounded by the upper edge Q1 and both side edges Q2 of the drain hole 20 is formed in a square shape 20b perpendicular to the short pipe 21. The area in which the square shape 20b is formed is within the area surrounded by the upper edge Q1 and both side edges Q2 of the drain hole 20 and on the upper half of the drain hole 20. The height H of the bowl 4 of the square shape 20b projecting from the inner surface 14a of the bowl is within the range of 1 to 5 mm. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to a toilet device, and relates to a technique for preventing trap clogging due to stool (solid matter) after stool.

  Conventionally, according to Patent Document 1, as shown in FIG. 5, in the toilet apparatus 1, a bowl upper portion 2, a rim portion 3, and a pedestal portion 4 that are above the central portion of the bowl are integrally formed with ceramics. The lower end surface of the ceramic bowl upper portion 2 is a flat surface, and is provided with a flange portion 9 that engages with the trap unit 5.

  In the trap unit 5, the bowl lower part 6, the trap part 7 and the drainage channel 8 are made of synthetic resin and formed integrally. The trap unit 5 has an upper surface and a lower surface that are horizontal, and a trap portion 7 and a drainage channel 8 are formed so as to penetrate the inside.

  The bowl lower portion 6 opens to the upper surface of the trap unit 5, and the end portion of the drainage channel 8 opens to the bottom surface of the trap unit 5. The trap unit 5 is bonded to the lower end surface of the bowl upper portion 2 with an adhesive.

Thus, in the toilet apparatus 1, since the synthetic resin is used for the complicated shape portion on the downstream side of the bowl lower portion 6, the dimensional accuracy of this portion can be easily increased by molding or the like. For this reason, since the inner surface of the drainage channel and the like becomes smooth and the water flow resistance is reduced, trap clogging can be prevented.
No. 7-28226

  However, since the toilet device of Patent Document 1 is formed of two types of parts made of earthenware and synthetic resin, there is a problem that the manufacturing process is complicated and leads to an increase in cost. In addition, there is a problem that the peripheral edge of the drainage port is round and clogged when the solid is long and large.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a toilet device that can prevent a clogging trap by smoothing the flow of solid matter with an inexpensive and simple configuration.

  The invention of claim 1 is a toilet device, characterized in that a peripheral edge portion of a drain outlet provided in a bowl surface of a toilet body is formed in a square shape with the bowl surface.

  A second aspect of the invention is the toilet device according to the first aspect, characterized in that the angularly formed peripheral edge is a region of the upper edge and both side edges of the discharge port.

  A third aspect of the present invention is the toilet device according to the second aspect, wherein an upper edge portion formed in a square shape is formed horizontally.

  According to the invention of claim 1, since the peripheral part of the drainage port is formed in a square shape with the bowl surface, the solid matter can be easily cut and crushed by the peripheral part sharpened in a square shape. The solid matter can be easily discharged together with the washing water. For this reason, the flow of solid matter can be made smooth with an inexpensive and simple configuration, and trap clogging can be prevented.

  Due to the square shape, a vortex turbulence is generated at the peripheral edge of the drain outlet. For this reason, compared with the case where the peripheral edge is continuously formed in a streamline shape from the bowl surface and the washing water is laminar, the solid matter is caught along the corners and collides when crushing into the drain outlet. Since the probability of trapping increases, trap clogging can be prevented more effectively.

  According to the invention of claim 2, since the peripheral edge is a region of the upper edge portion and both side edge portions of the discharge port, solid matter collides with the region of the upper edge portion and both side edge portions, and the discharge port. Since the lower edge portion is streamlined, the state in which the flow rate of the washing water as a whole is not impaired can be maintained.

  For this reason, the same effect as that of the invention of claim 1 can be obtained without causing the solid matter to collide with the square shape and changing the draining effect of the washing water.

  According to the invention of claim 3, since the upper edge portion is formed horizontally, eddy turbulence is generated more significantly in the peripheral edge portion as compared with the shape of the arc-shaped peripheral edge portion. The same effects as those of the invention can be obtained with certainty.

  Below, the 1st Embodiment of this invention is described based on FIGS. 1-3.

<Configuration of toilet device>
As shown in FIGS. 1, 2, and 3, in the toilet device 11 according to the embodiment of the present invention, the toilet body 12 includes a skirt portion 13, a bowl 14, and a rim portion 15, and a hinge-type toilet seat 16 and a toilet lid 17. Is provided.

  A drain outlet 20 is provided in the lower part of the bowl 14, and the drain outlet 20 is connected to a horizontal short pipe 21, and the short pipe 21 is guided to a sewer pipe through a trap (not shown).

  When the user cleans the bowl 14 with the cleaning water P after the stool, the solid K is carried to the cleaning water P and discharged from the drain port 20.

  Here, the flow path extending from the bowl 14 to the short pipe 21 is connected in a generally streamlined manner in order to reduce the resistance in the pipe as much as possible and flow the solid matter smoothly, but the upper edge Q1 in the peripheral edge 20a of the drain port 20 and The region of both side edge portions Q2 is formed in a square shape 20b perpendicular to the short tube 21.

  More specifically, the upper edge portion Q1 and the side edge portions Q2 are regions of the upper half of the drainage port 20.

  The protruding height H from the inner surface 14a of the bowl 14 of the square shape 20b is provided in the range of 1 mm to 5 mm. The square 20b is integrally formed with the bowl 14 and the short tube 21 with resin or ceramics.

<Operation of toilet device>
Since the peripheral edge portion 20a of the drainage port 20 has the square shape 20b formed at right angles to the bowl 14, the solid matter K collides with the square shape 20b when the solid matter K flows into the drainage port 20 and is crushed. it can.

  Furthermore, since a vortex turbulent flow is generated in the vicinity of the square shape 20b, the solid matter K is easily caught in the vortex flow when it flows into the drain port 20, and easily collides with the square shape 20b.

  For this reason, since the solid substance K can be easily crushed by the shock of collision and the right-angled corners 20b, the solid substance K can be easily discharged.

  Moreover, since it is a simple structure which only forms the square shape 20b, the big effect that a trap clogging can be prevented without cost increase is acquired.

<Second Embodiment>
A second embodiment of the present invention will be described with reference to FIG. In addition, since the structure of the toilet device of 2nd Embodiment is completely the same as the structure of 1st Embodiment shown in FIGS. 1-3, the description and drawing are abbreviate | omitted.

  As shown in FIG. 4, the rectangular shape 20 b is formed in the upper edge portion Q <b> 1 and the side edge portions Q <b> 2 that are the upper half region of the drain port 20, and the upper edge portion Q <b> 1 is formed horizontally.

  Since the upper edge portion Q1 protrudes to the inner side of the drainage port 20 from the other region of the peripheral edge portion 20a, the eddy turbulence is likely to be generated, and the upper edge portion Q1 is formed horizontally and cleaned. Since the water P is more likely to collide, a strong vortex flow is generated. For this reason, since the solid substance K collides more strongly with the horizontal upper edge part Q1 which is the square shape 20b, and is crushed, the solid substance K can be crushed effectively.

  The embodiment of the present invention has been described with reference to the drawings. However, the specific configuration is not limited to this embodiment, and design changes and the like within the scope of the present invention are included in the present invention. It is.

  For example, the total area of the upper edge portion Q1 and the side edge portions Q2 of the drain port 20 can be appropriately determined in consideration of the shape of the bowl and the like regardless of the upper half region of the drain port 20.

  The angle of the square shape 20b with respect to the inner surface 14a of the bowl 14 of the peripheral edge 20a of the drain port 20 may be an angle other than a right angle.

  The protrusion height H of the square 20b from the inner surface 14a of the bowl 14 can be set based on the type and size of the toilet regardless of the range of 1 mm to 5 mm.

  The rectangular shape 20b can be formed intermittently rather than continuously at the peripheral edge 20a.
