A water-saving device that addresses the problem of saving drinking water when using flush toilets, such as in households and in public facilities. The device has a hollow profile of a guiding part, into which a hollow inner profile with a collection container is inserted. The device is not a part of the toilet but can be easily connected to it and used at any time. The device can be used on both the inside and outside of the toilet, for men, women and children.

A flush toilet includes a rear storage configured to store a control unit of a toilet main body. The rear storage includes a supporting wall configured to support the control unit so as to divide a storage region of the rear storage into upper and lower regions. In a rear supporting region of the rear storage, a first distance in a horizontal left-right direction from an outer joining portion to an inner joining portion in the supporting wall is shorter than a second distance in the horizontal left-right direction from an outer wall in the double wall of the skirt to an inner joining portion of the supporting wall. The second distance is set to a maximum width dimension in the left-right direction in an internal space of the double wall of the skirt.

A urinary device is attachable to a toilet and assists males in directing a flow of urine into the toilet. The device is installed between a toilet seat and tank and pivots to a vertical or near vertical position against the tank when not in use. A telescoping portion extends for tall or short males. The device may be installed on any standard toilet in a few minutes. A bypass may be included to direct urine into a drain avoiding the toilet bowl and the need to flush the toilet. The urinary device reduces or eliminates germs and odors on or around the toilet and is easy to clean using water and a household cleaner.

Disclosed are devices, methods, and systems for generating and applying a magnetic field in a toilet. A toilet including a bowl having a discharge outlet, a trapway in fluid communication with the discharge outlet, and at least one magnet configured to generate a magnetic field to alter a flow of liquid through the trapway is described.

Systems for monitoring metabolites may include a sample collection system and a urinalysis system of or for a toilet. The sample collection system may be automated to collect sample urine from a toilet or toilet area, transport the sample to the urinalysis system, and/or the sample urine for analysis at a later time or after analysis by the urinalysis system. The urinalysis system may be automated by proactively providing test material on which a subject may provide a urine sample. Once the urine sample has been provided the urinalysis system may provide the test material to an analyzer for analysis. Results of the analysis of the test material and sample urine may be provided to a mobile device of the subject and/or a remote server. The urinalysis system may provide a urine sample to a mass spectrometry unit for analysis.

A flush toilet includes a toilet main body made of ceramics and a rear storage configured to store at least a part of a control unit. The rear storage includes a supporting wall that divides a storage region into upper and lower regions and that joins left and right side walls of the skirt and the water discharge trap. The supporting wall includes a horizontal wall that extends in a horizontal direction from a joining portion between the supporting wall and the water discharge trap, and left and right lower walls that are provided outside the horizontal wall in a left-right direction and below the horizontal wall and that are joined to the left and right side walls of the skirt. The left and right lower walls on a rear side are separated in the left-right direction by the horizontal wall.

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.

A flush toilet includes a toilet main body made of ceramics, a control unit, a supply source that enables water supply or power supply to the control unit, and a flexible elongated member connecting the supply source and the control unit. The toilet main body includes a rear storage configured to store at least a part of the control unit. The rear storage includes an upper storage region, a lower region, and a lower communication region. The flexible elongated member extends from an upper connecting end portion toward a lower connecting end portion, to be inserted from the upper storage region into the lower communication region, and then extends from inside of the lower communication region to outside of the toilet main body, without extending through the lower region.
