- Patent Document 1 Japanese Utility Model Publication No. 3-128774 describes a wall-mounted one-piece toilet. Since such a wall-mounted flush toilet is installed away from the floor surface, it has advantages such as good cleanability of the floor surface and is being widely adopted in general.
- Patent Document 2 Japanese Patent Application Laid-Open No. 2004-100307
- Patent Document 2 describes a flush toilet in which the bowl surface of a toilet bowl is washed with a swirling flow of washing water discharged from the upper part of the bowl portion.
- the flush toilet that cleans the bowl surface with such a swirl flow is simple in shape because there is no box rim or the like that discharges the wash water downward from the edge of the bowl. Generally, it is widely used because of its excellent cleaning properties.
- Patent Document 1 Japanese Utility Model Publication No. 3-128774
- Patent Document 2 JP 2004-100307 A
- the cleaning method for cleaning the bowl portion by swirling flow has a problem that it is difficult to apply to a flush toilet that is difficult to cause a strong siphon action, such as a wall-mounted toilet. .
- an object of the present invention is to provide a flush toilet that can effectively discharge filth by a washing method using a swirling flow without using a strong siphon action.
- a first invention of the present invention is a flush toilet that flushes toilets with washing water and discharges waste, and has a bowl-shaped waste receiving surface, A rim portion with an inner wall surface of the rim projecting inward, and a bottom portion of the bowl portion that communicates with the bottom of the bowl portion so as to discharge dirt in the bowl portion.
- a trap pipe that regulates the water level, a first shelf formed along the rim on the upper edge of the filth receiving surface, and below the first shelf and above the initial accumulated water level 2nd shelf part formed on the sewage receiving surface, 1st water discharge part which spouts washing water on the 1st shelf part and forms swirl on the sewage receiving surface, and washing on the 2nd shelf part
- a second water discharge part that forms a flow for discharging water and stirring the wash water in the bowl part, and a first for supplying the wash water to the first water discharge part And waterways, is characterized by having a second water passage for supplying cleaning water to the second water portion.
- the cleaning water discharged from the first water discharge section flows along the first shelf when the bowl section is cleaned, and the bowl section receives the filth receptacle while swirling. Clean the surface and flow into the bottom of the bowl.
- the wash water discharged from the second water discharge part flows down along the second shelf part to the bottom part of the bowl part, and stirs the accumulated water in the bowl part up and down.
- the water in the bowl is agitated and floats on the surface of the water before washing.
- the suspended waste that had been sunk is submerged in the stored water, and the suspended sewage is discharged through the trap line together with the waste that has submerged in the stored water and the wash water.
- the washing water discharged from the second water discharger stirs the stored water and sinks the suspended filth in the stored water, so the ability to stir the stored water is low. Floating waste can be reliably discharged even in flush toilets using swirling flow.
- the second shelf is formed in the vicinity of the highest height at which the water level of the bowl rises during cleaning.
- the wash water discharged from the second water discharge section has a water level slightly higher than the second shelf or slightly lower than the second shelf from the second shelf. Since it flows into the stored water, water is discharged from the first water discharge section, and the collision with the wash water that swirls and flows down through the first shelf section can be avoided. Can be effectively stirred.
- the second shelf portion extends from the rear portion of the bowl portion to the side portion.
- the wash water discharged from the second water discharge portion flows along the second shelf portion, hits the tip of the second shelf portion located on the side surface portion of the bowl portion, Flow into.
- a part of the washing water discharged from the second water discharge portion flows down from the side surface portion of the bowl portion, and therefore the axis extending in the front-rear direction of the bowl portion is the center.

- the wash water discharged from the second water discharge part flows from the front of the bowl part toward the inlet of the trap pipe, and stirs the accumulated water in the bowl part up and down. As the accumulated water in the bowl is agitated, the suspended filth floating on the surface of the accumulated water before washing is submerged in the accumulated water. Discharged through.
- the washing water discharged from the second water discharge unit stirs the stored water and sinks the suspended filth in the stored water, so the ability to stir the stored water is low. Floating waste can be reliably discharged even in flush toilets using swirling flow.
- the second water discharge portion is formed in the vicinity of the highest height at which the water level of the bowl portion rises during cleaning.
- the wash water discharged from the second water discharger has a water level slightly higher than the second water discharger or slightly lower than the second water discharger from the second water discharger. Since it flows into the stored water, water is discharged from the first water discharger and flows while turning through the first shelf. It is possible to avoid collisions with the wash water that falls, and to effectively agitate the stored water while preventing splashing of the wash water.
- the water level in the bowl portion is always equal to or higher than the initial water level.
- the siphon action is generated, and the siphon action is very weak, so that it is difficult to discharge the filth that is suspended by the siphon action. It is.
- trapped line force can be reliably discharged even when floating dirt without using the siphon action is used.
