Description

In order to achieve the above-mentioned object, the present invention is a flush toilet that flushes a toilet bowl with flush water supplied from a water supply source to discharge dirt, and has a bowl-shaped waste receiving surface and the waste receiving surface. A rim portion located above and a concave portion formed below the waste receiving surface, the bottom portion having the concave portion located below the accumulated water level, and the bottom surface and the lower edge portion of the waste receiving surface. A wall portion that connects the wall portion and a water discharge portion that supplies cleaning water into the bowl portion, and is located at the rim portion on one side in the left-right direction of the bowl portion and at the same time. the to jetting water and the first rim water spouting portion, as well as positioned in the rim portion of the other side in the lateral direction of the bowl portion, the washing water toward the one side of the bowl portion for spouting flush water toward the front and 2 rim spouting portion, and the water discharge portion having a chisel Anda drain line for discharging waste its inlet is connected to said recess, said bowl portion, flows into the recess from the front side of the flush water spouted from the first rim spouting portion the bowl portion It is configured to form a main flow to forward the mainstream the recess of the washing water flowing from the second rim spouting unit spouting is the second rim spouting portion from sideways toward the rear of the waste receiving surface of the recessed portion Before it swirls to the filth-receiving surface, flows into the recess , merges with the main stream from the first rim spout in the recess , and sinks the filth in the bowl into the accumulated water. Is characterized by.
In the present invention thus configured, the cleaning water spouted from the first rim spouting part flows into the recess as a main flow from the front side of the bowl part, and the second rim spouting water flows into the main flow flowing into the recess. Since the wash water discharged from the portion merges in the lateral direction, the accumulated water in the recess can be effectively stirred in the vertical direction. Therefore, the waste receiving surface of the bowl portion can be sufficiently washed with the washing water spouted from each of the first rim water spouting portion and the second rim water spouting portion, and a vertically stirring flow is generated in the recess. be able to. As a result, the waste in the bowl portion can be submerged in the accumulated water and efficiently discharged into the drainage pipe, and the waste discharge performance can be improved.
Further, for example, in the present invention configured as described above, the cleaning water discharged from the first rim water discharge part flows into the recess from the front side of the bowl part as a main flow, and the main flow flowing into the recess is changed to the second flow. Most of the wash water spouted from the rim spouting portion joins from the lateral direction, so that the accumulated water in the recess can be effectively stirred in the vertical direction. Therefore, the waste receiving surface of the bowl portion can be sufficiently washed with the washing water spouted from each of the first rim water spouting portion and the second rim water spouting portion, and a vertically stirring flow is generated in the recess. be able to. As a result, the waste in the bowl can be submerged in the accumulated water and efficiently discharged into the drainage pipe, and the waste discharge performance can be improved.
