Abstract
A sump for a toilet includes a first end of the sump, defined by a first boundary, and a second end of the sump, defined by a second boundary. The sump includes a channel running from the first end of the sump to the second end of the sump defined by a sump surface. The first end of the sump is configured to receive liquid and the second end of the sump is configured to supply liquid. The sump has a sump can-cut diameter corresponding to a diameter of the channel at the first end of the sump, a sump side radius extending from a center of the channel to an inner surface of the channel, and a sump depth corresponding to a largest vertical distance within the channel. The sump may be drain cast using a single continuous pathway.
Claims15
An assembly for a toilet, including a sump, the sump comprising:
- a first end of the sump, defined by a first boundary;
- a second end of the sump, defined by a second boundary;
- a channel running from the first end of the sump to the second end of the sump defined by a sump surface;
- a drain channel;
- and
- a jet orifice fluidly connected to the drain channel and the sump, the jet orifice configured to deliver liquid to the sump,
- wherein the first end of the sump is configured to receive liquid and the second end of the sump is configured to supply liquid,
- wherein the sump has a sump can-cut diameter corresponding to a diameter of the channel at the first end of the sump, a sump side radius extending from a center of the channel to an inside surface of the channel, and a sump depth corresponding to a largest vertical distance within the channel, and
- wherein the drain channel, jet orifice, and sump are drain cast using a single continuous drain cast pathway fluidly connecting the drain channel, the jet orifice, and the sump, such that a smooth and continuous curved surface is formed by the drain channel, the jet orifice, and the sump.
A toilet, comprising:
- a bowl;
- a sump including a channel fluidly connected to the bowl, the sump having a can-cut diameter corresponding to a diameter of the channel at a location where the channel is fluidly connected to the bowl, a sump side radius extending from a center of the channel to an inside surface of the channel, and a sump depth corresponding to a largest vertical distance within the channel;
- a drain channel;
- a jet orifice fluidly connected to the drain channel and the sump, the jet orifice configured to deliver the liquid to the sump;
- and
- a trapway, fluidly connected to the sump,
- wherein, the drain channel, jet orifice, sump, and trapway are drain cast using a single continuous drain cast pathway fluidly connecting the drain channel, the jet orifice, the sump, and the trapway, such that a smooth and continuous curved surface is formed by the drain channel, jet orifice, and sump.
