A toilet apparatus according to an embodiment includes a human body detector and a controlled part. The toilet apparatus is mounted to a toilet. The human body detector radiates a radio wave and detects a human body based on the signal that is obtained. The human body detector outputs a control signal based on the detection result. The controlled part is controlled based on the control signal. The human body detector has two or more establishment times from when the signal is obtained until when the detection result based on the signal is established.

A sanitary washing device according to an embodiment includes a toilet seat, a main part, and a radio wave sensor. The toilet seat is provided on a toilet. The toilet seat is pivotally supported by the main part. When the toilet seat is closed, the user in front of the main part is detected by the radio wave sensor in a first region, and in a second region higher than the first region. When the toilet seat is open, the user in front of the main part is not detected in the first region by the radio wave sensor, but the user in front of the main part is detected in the second region by the radio wave sensor. The position of the radio wave sensor is not changed between the state in which the toilet seat is open and the state in which the toilet seat is closed.

The present invention is directed to a toilet that includes a liquid level sensor on the surface of a flush jet fill tube. The liquid level sensor is a noncontact electrical impedance sensor that is an electrical capacitor. The capacitor may be used alone or with other volume sensors to detect volume of materials added to a toilet bowl. Some embodiments include a processor which records data and provides reports that may be clinically useful to assess the user's health status. The temporal nature of the liquid level sensor measurements is particularly useful because urination or defecation may be measured over time. Not only are total volumes detected but rates at which waste is deposited into the toilet during the entire excretion event are detected. These measurements are particularly useful in assessing certain health conditions.

Improvements in a toilet flush system where the flush is not determined only by a simple gravitational flow of the water tank content. The Flush-All provides a quick flush, as soon as the flush handle is released the flushing stops. There is no sticking of the flushing flapper, leaky flapper, leaky O-rings, sticky plungers, wasted water flow by improperly adjusted water level height as water continuously flows over the overfill tubing, or defects in the incoming water automatic shut off system or the noise that accompany such continuous flow. The Flush-All provides a universal design that can be used on most toilet bowls systems, a simple retrofitting procedure using a universal mounting base that is retrofitted to most existing toilet bowl. The only part to be replaced is the toilet tank. It is a quick and easy procedure that requires no structural damage or repair to the bathroom.

A water consumer system comprising a water consumer that comprises a water receptacle, the water consumer system further comprising a fluid inlet with an inlet valve, a fluid outlet, at least one HF motion sensor for detecting fluid motion provided on the water receptacle and/or at the fluid outlet and a water consumer controller coupled with the HF motion sensor and the inlet valve, wherein the water consumer controller comprises a data processing system, which is arranged to Retrieve or receive data captured by the HF motion sensor, to evaluate the data arithmetically and, based on the evaluated data, to detect one of the following malfunctions or initiate an action, in order to prevent one out of the variety of the following malfunctions, such as that the outlet is obstructed, there is a pressure fluctuation in a wastewater system, the fluid inlet is malfunctioning, etc.

A flush toilet of present invention includes a bowl that includes a bowl-shaped waste receiving surface, a rim formed above the waste receiving surface, and a pooled water portion formed below the waste receiving surface, a discharge passage that has an inlet connected to the pooled water portion and discharges waste, and a spout portion that spouts flush water onto the bowl and forms a swirling flow on the waste receiving surface. The waste receiving surface of the bowl has a sectorial recess that is formed between a front end portion of the waste receiving surface and a front end portion of the pooled water portion so as to spread from the pooled water portion toward the front end portion of the waste receiving surface.

Proactive methods and articles of manufacture are disclosed for preventing any water leak or flooding of a toilet. These methods and systems can replace or be added to the water system of existing toilets, especially the North American toilets, which use water tanks. In various embodiments the water is turned OFF and prevented to enter the toilet tank before the flush handle is activated and/or before a user is sensed. In some embodiments each flushing of the toilet permits the toilet tank to only fill once. If a leak causes the tank to empty, water is not permitted to fill the leaking tank until the next time the flush handle is activated. In some other embodiments each flushing of the toilet and/or sensing of a user permits the toilet tank to fill a predetermined number of times.

A method of manufacturing a thermoplastic resin for a household plumbing equipment includes: reacting an acid component including a terephthalic acid and a glycol component including a trimethylene glycol derived from a plant to form a poly trimethylene terephthalate resin as a condensation polymer of a formed glycol ester; and combining the poly trimethylene terephthalate resin with a polymethyl methacrylate resin in a mass ratio of 90:10-50:50 to form a thermoplastic resin, wherein the thermoplastic resin includes the polymethyl methacrylate resin and the polytrimethylene terephthalate resin in an amount of 80% or more by mass of a total amount of the formed thermoplastic resin.

A rimless toilet pan (20) includes a forward end (F), a rearward end (R) and a pan bowl (28). A flushing outlet (32) is in fluid communication with the pan bowl (28). A flushing water inlet (30) is in fluid communication with the pan bowl (28). An inwardly facing first sidewall (34) extends substantially around the top of the pan bowl (28). A substantially horizontal ledge extends (36) substantially around the bottom of the first sidewall (34). An inwardly facing second sidewall (37) extends substantially around the pan bowl (28) under the horizontal ledge (36). A flushing water flow splitter (38) is substantially adjacent a rearward end of the first sidewall (34), the flow splitter (38) is in fluid communication with the flushing water inlet (30) and has a leftwards outlet (38a) and a rightwards outlet (38b). A flushing water flow balancer (40) is on a frontwards part of the first sidewall (34), the flow balancer (40) including an inwardly facing projection (40a, 40b, 40c) extending vertically through at least part of the height of the first sidewall (34) and being positioned substantially symmetrically in relation to a forward to rearward centerline of the toilet pan (20). The flow balancer (40) includes leftward (40a) and rightward (40b) angled surfaces which meet at an innermost edge (40c) that is substantially aligned with the forward to rearward centerline of the toilet pan (20). The leftward (40a) and rightward (40b) angled surfaces are substantially triangular in shape and taper from a relatively wide lower part to a narrowed or pointed upper part.

An interactive device that is an accessory to a flush toilet and is positioned at the rear of the flush toilet and may be attached to the rear of the toilet such that the user would use the flush toilet in the reverse position. The interactive device may include a toy, game, computer, or projector. The interactive device may be secured to the toilet by straps or to the toilet lid hinges and may be detachable from the flush toilet. The interactive device may be a seat insert with a projector to display images on the toilet lid or cistern. The interactive device makes going to the bathroom enjoyable for both the child and parent, while educating the child to appreciate and to become more accustomed to using a flush toilet.
