Abstract: A toilet having a water inlet structure, a bowl structure, a rim, and an outlet structure. The water inlet structure is configured to receive water from a water source. The bowl structure includes a toilet bowl and a water channel, which is fluidly connected to the water inlet structure and is configured to feed water into the toilet bowl from an outlet of the water channel that is located between a back portion and a side portion of the toilet bowl. The rim has a solid, annular member disposed around a top of the toilet bowl and entirely above the water channel, is formed separately from and coupled to the bowl structure. The outlet structure is fluidly connected to the toilet bowl to carry the water and contents from the toilet bowl to an outlet.

Abstract: A flush toilet wherein the rim inside wall portion comprises a rim inside wall upper sloped surface, and an improvement in user visibility and user rim portion cleanability is sought, flush water can be constrained from splashing outside the bowl portion by traveling by centrifugal force along the rim inside wall upper sloped surface from the inside surface formed at a relatively low height. The rim portion of the flush toilet of the invention includes a rim inside wall portion; the rim inside wall portion comprises a rim inside wall upper sloped surface, and an inside surface vertically extending straight up to the rim inside wall upper sloped surface; and the water supply apparatus comprises a constant flow rate valve for spouting a predetermined constant flow rate of flush water from the water spouting portion.

Abstract: A switching mechanism is configured to switch an advancing direction of water injected from a nozzle by moving between a first position and a second position. The switching mechanism is held at the second position by a force received from the water injected by the nozzle during the tank water feeding process. A refill mechanism has a refill pipe for causing the water injected from the nozzle during the tank water feeding process and whose advancing direction is switched by the switching mechanism to flow in through an inflow port on one end side. The refill pipe is configured to lead the water having flowed in through the inflow port to a toilet stool body without flowing through a suction port of a throat pipe.

Abstract: A flush toilet which is capable of completing flushing of a bowl portion at or before termination of a siphon action, thereby improving toilet flushing performance in a situation where flushing is performed while generating a siphon action by using a reduced amount of flush water. The flush toilet is configured such that, after a first rim water spouting portion starts to spout flush water therefrom, a jet water spouting portion and a second rim water spouting portion start to spout flush water therefrom, in this order.

Abstract translation: 一种冲水马桶，其能够在虹吸作用终止期间或之后完成碗部的冲洗，从而在通过使用减少量的冲洗水产生虹吸作用的同时进行冲洗的情况下提高马桶冲洗性能。 冲水马桶被配置为使得在第一边缘喷水部分开始从其中喷出冲洗水之后，喷射水喷射部分和第二边缘喷水部分依次开始喷出冲洗水。
