Problems solved by technology

[0008] However, attempts to develop fast flushing action with effective cleaning and less water use are hindered by "back flow," a type of trap that causes reverse airflow from the pipe to the low-pressure area of ​​the trap. trend

Embodiment Construction

[0032] figure 1 A water closet 10 is shown with a design of the siphon channel or trap 12 according to the invention. In particular, other than trap 12, toilet 10 may be any suitable toilet, preferably one designed for low flush volume.

[0033] For example, figure 1 A two-piece toilet with a separate flush tank 14 mounted to a toilet base 16 is shown in phantom. A hole (not shown) in the bottom of the flush tank 14 is aligned with a hole (not shown) in the top of the toilet base 16 so that during a flush cycle, water can flow from the flush tank through the hole and into the seat formed in the toilet. In the toilet 18 in the base 16 .

[0034] Extending along a serpentine path from an opening 20 in the toilet bowl 18 is a trap 12 that has a generally uniform and constant circular cross-section (eg, image 3 shown). This section occurs at least at the second bend 30 of the weir 34 .

[0035] The trap has a discharge opening 22 at the bottom of the toilet base 16 which fi...

Abstract

A toilet has a trapway extending between a bowl opening and an outlet opening. The trapway defines a curved, preferably uniform circular cross-section water dam region above the bowl opening, a down leg, and a straight out leg between the down leg and the outlet opening. The down leg has a rearward slope where is located a horizontal baffle. The inclined down leg and horizontal baffle work in concert to prevent the back flow of air to a region above the dam as well as to facilitate rapid entrainment and evacuation of air below the dam.

Description

technical field [0001] The present invention relates to a water closet with an improved trapway. Background technique [0002] A conventional water closet has a toilet portion and a cistern portion, usually formed as one or two main parts. Serpentine pathways are typically located under the rear of the toilet to transfer the contents of the toilet to the building's sewage / sewage / rot pipes. This channel is commonly referred to as a "siphon" or "trap". [0003] The upper pipe portion of the channel is usually filled with water to "seal" the sewage odor downstream from it, thereby preventing the odor from entering the interior of the building. Water is held in the toilet bowl and the upper pipe of the trap by the curved portion of the trap. When the normally air / steam filled downstream portion of the trap rapidly fills with water during the flush cycle, the trap (sometimes with adjacent nozzles) creates a siphon that empties the toilet bowl. [0004] Thus, the trap helps to...
