Flush toilet

Abstract

The flush toilet of the present invention has: a bowl portion (14) including a waste receiving surface (20), a rim portion (22), a shelf portion (24), and a concave portion (26); a discharge passage (18) for discharging waste; a first spout port (28) for spouting flush water on a shelf portion (24) of the bowl portion (14) to form a circulating flow; a second spout port (30) for spouting flush water in the same direction as the circulating direction of flush water spouted from a first spout port (28) and toward the rear of the bowl portion (14); a first water conduit (32) for supplying flush water to the first spout port (28); and a second water conduit (34) for supplying flush water to the second spout port (30). The first and second water conduits (32, 34) are formed so that the flow rate of flush water spouted from the second spout port (30) is greater than the flow rate of flush water spouted from the first spout port (28).

Description

technical field [0001] The present invention relates to a flush toilet, and more particularly, to a flush toilet that cleans the toilet and discharges waste using cleansing water supplied from a cleansing water source. Background technique [0002] In the past, for example, as shown in Patent Document 1, a flush toilet is known, which has: a basin, a basin-shaped dirt receiving surface, an inner edge portion positioned at the upper edge, and a dirt receiving surface formed on the upper edge. The concave portion below the surface, the concave portion has a bottom surface located below the water level of the accumulated water, and a wall surface connecting the bottom surface and the lower edge of the dirt receiving surface; One side spouts the washing water toward the front of the basin at the same time, forming a swirling vortex flow along the inner peripheral surface of the inner edge; The inner peripheral surface of the rim part spouts cleaning water to form a swirl flow i...

AI Technical Summary

Problems solved by technology

[0004] In such a flush toilet described in Patent Document 1, since the cleansing water jetted from the second rim jetting part and flowing into the concave part is merged from the side of the bowl to the flushing water jetted from the first rim jetting part and flows into Since the cleaning water reaches the concave portion, there is a problem that the ability to cause swirling flow in the vertical direction that stirs the accumulated water in the concave portion in the vertical direction is reduced.

[0005] And, because it is configured that the washing water discharged from the second rim water jetting unit and flowed into the concave portion from the lateral direction merges with the main flow of washing water jetted from the first rim water jetting unit and flows into the concave portion from the front side of the bowl portion, There is a problem that it is difficult to form a vertical swirling flow
