Description

  The present invention forms a rim water passage around the upper edge of the bowl portion, connects a rinsing water supply pipe to the rim water passage, and forms a plurality of spray holes that open to the bowl portion side. The present invention relates to a flush toilet that cleans the bowl portion by discharging flush water from the spray hole, and is less likely to leave the rinse water in the rim water passage for a long time after washing. More specifically, the present invention relates to a flush toilet in which a mesh-like water flow groove communicating with each other is formed in the bottom wall of the rim water passage, and at least one groove of the mesh-like water flow groove is open to the spray hole. .

  The flush toilet forms a rim water passage around the upper edge of the bowl portion, and connects a rinsing water supply pipe to the rim water passage and forms a plurality of spray holes that open to the bowl portion side. The bowl portion is washed by discharging washing water from the water spray holes, which is excellent in terms of hygiene. However, because wash water is used, the wash water may remain in the rim waterway, and this residual wash water may freeze or condense in the winter and may cause mold. It was.

For this reason, there is a demand for a flush toilet with little risk of washing water remaining in the rim water passage after washing. For example, a flush toilet shown in Patent Document 1 has been proposed. That is, the drainage of the cleaning water is promoted by making the rim water passage a V-shaped bottom face (valley). However, this conventional flush toilet is not sufficient to prevent residual washing water from remaining in the form of a thin film (wet state) on the entire bottom surface, and is prone to freezing and dew condensation. It was a cause.
Japanese Utility Model Publication No. 7-8475 (Summary and FIG. 5)

  It is an object of the present invention to prevent residual washing water remaining in the rim water passage of the flush toilet from the spray hole to prevent the residue from remaining for a long time and to prevent freezing, condensation, and mold. It is.

  In order to solve the above-mentioned problems, a flush toilet according to the present invention has a structure in which a rim water passage is formed around the upper edge of the bowl portion, and a flush water supply pipe is formed in the rim water passage. In the flush toilet comprising a plurality of spray holes that open to the bowl portion side, a mesh-like water passage groove communicating with each other is formed on the bottom wall of the rim water passage, At least one groove is formed in the spray hole.

  In the flush toilet according to claim 1, a rim water passage is formed around the upper edge of the bowl portion, and a water supply pipe is connected to the rim water passage, and a plurality of water spray holes opened to the bowl portion side are provided. In the flush toilet formed, the rim water passage bottom wall is formed with a mesh-like water passage groove communicating with each other, and at least one groove of the mesh-like water passage groove is formed in the spray hole. Residual cleaning water is drained from the mesh water channel that opens to the spray hole, and suction force in the direction of the spray hole acts on the other residual cleaning water in the mesh channel, and the residual cleaning water is sequentially discharged from the spray hole. The For this reason, the remaining washing water remaining in a thin film form also enters the mesh-like water passage sequentially and is discharged to prevent the remaining for a long time.

  The flush toilet according to claim 2 has a rim water passage bottom wall extending in the direction of the water passing through the valley, forming a water spray hole in the bottom of the valley and communicating with each other on the surface of the valley. The flush toilet according to claim 1, wherein the flush toilet bowl according to claim 1, wherein the residual washing water is easy to move in the direction of the spray hole, and drainage from the spray hole by the mesh water flow groove is more efficiently performed. Is to be done.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. 1 is a partially cutaway plan view of a flush toilet according to an embodiment of the present invention, FIG. 2 is a cross-sectional view of the embodiment shown in FIG. 1, FIG. 3 is an enlarged view of a main part of the embodiment shown in FIG. FIG. 5 is an enlarged sectional view of a main part of the embodiment shown in FIG. 1, and FIG. 5 is an enlarged view of a main part of a different embodiment of the present invention.

  In FIGS. 1 and 2, 1 is a flush toilet, 2 is a rim water passage, 3 is a water spray hole, and 4 is a mesh water flow groove. In the flush toilet 1, a rim water passage 2 is formed around the upper edge of the bowl portion 5, a wash water supply pipe (not shown) is connected to the rim water passage 2, and the wash water is sprayed from the spray holes 3. The surface of the bowl part 5 is washed.

  As shown in FIG. 3 and FIG. 4, the mesh water passage groove 4 is formed in the bottom wall 6 of the rim water passage 2 and communicates with each other. In other words, they are not independent of each other but connected to each other, and are formed in a mesh shape. The mesh water passage groove 4 is such that at least one groove 7 is open to the spray hole 3.

  When a rinsing water supply pipe is connected to the rim water passage 2 and the surface of the bowl portion 5 is washed by spraying the washing water from the water injection hole 3, the residual washing water is formed in a film on the bottom wall 6 of the rim water passage 2. It often remains for a long time. In this flush toilet 1, a mesh-like water channel 4 is formed in the bottom wall 6 of the rim water channel 2, and at least one groove 7 is opened in the water spray hole 3. Residual washing water flows down to the spray hole 3.

  The groove 7 constitutes the mesh-shaped water flow groove 4, and is connected to each other, so that there is an action of capillary action and is drawn in the direction of the spray hole 3 through the mesh-shaped water flow groove 4. 7, residual washing water flows into the spray hole 3. When the residual cleaning water in the mesh water flow channel 4 decreases, the residual cleaning water falls in the form of a film on the bottom wall 6 into the mesh water flow channel 4, and the residual cleaning water sequentially enters the spray hole 3 from the groove 7. Flows down and drainage from the spray hole 3 is promoted. For this reason, there is little possibility that the residual washing water will remain in the rim water passage 2 for a long time, and there is little possibility of condensation, freezing, and mold generation.

  In the flush toilet 8 shown in FIG. 5, 9 is a rim water passage, 10 is a bottom wall, 11 is a valley bottom, 12 is a water spray hole, and 13 is a mesh water passage. In the flush toilet 8, the bottom wall 10 of the rim water passage 9 is formed in a valley-like portion that extends in the direction of water passage, and a water spray hole 12 is formed in the valley-like bottom 11. The plurality of mesh-shaped water flow grooves 13 are formed in the bottom wall 10 of the rim water flow path 9 in a state of communicating with each other, and at least one mesh-shaped water flow groove 13 is open to the spray hole 12.

  In this flush toilet 8, the bottom wall 10 of the rim water passage 9 is formed in a valley-like portion that extends in the direction of water passage. The remaining washing water is discharged through the spray holes 12 more efficiently through the through holes to prevent the remaining for a long time. For this reason, this flush toilet 8 is also less likely to cause condensation, freezing, and mold.

The partially notched top view of the Example of the flush toilet concerning this invention. Sectional drawing of the Example shown in FIG. The principal part enlarged view of the Example shown in FIG. The principal part expanded sectional view in the Example shown in FIG. The principal part enlarged view of the Example from which this invention differs.
