A urine deflector is configured to attach to a toilet seat and is made of a monolithic structure comprising an arcuate top member having a planar top surface integrally formed with an arc shaped projecting portion, the arc shaped projecting portion projecting downwardly from the top member, the projecting portion integrally formed, at each end of the arc shape, with a gravity assist drain portion, each gravity assist drain portion extending from the projecting portion at an angle from 30° to 60° from a plane defined by a top surface of the top member that facilitates directing urine liquid into a toilet bowl when the toilet seat is in either a seated position or an open position.

A process for preparing a repellant smooth surface includes applying a coating composition onto a smooth surface of a substrate having hydroxyl functional groups thereon and an average roughness Ra of less than 4 μm. The coating composition includes: (i) a polymerizable silane or siloxane or both selected from the group consisting of dimethyldimethoxysilane, dimethoxy-methyl(3,3,3-trifluoropropyl)silane, dimethoxy(methyl)octylsilane, diethoxydimethylsilane, (ii) a solvent and (iii) an acid catalyst. The process further includes polymerizing the silane or siloxane or both from the hydroxyl functional groups on the smooth surface of the substrate to form a chemical layer of graft polymers having ends anchored to the smooth surface and applying a lubricant coating over the formed chemical layer to adhere and maintain the lubricant on the smooth surface and form a lubricant-entrenched smooth surface as the repellant smooth surface.

A coated smooth surface of a substrate repels liquids and viscoelastic materials and can have anti-staining and anti-biofouling properties. The smooth surface can be coated by applying a chemical layer on the surface and a lubricant. Such coated surfaces are useful for use in toilets, urinals, or other devices for the processing of liquids and viscoelastic materials such as solid or semi-solid metabolic waste of human digestive system. Such coated surfaces can also be applied to windows for buildings or vehicles such as automobiles or camera lenses to repel liquids (e.g. rain), ice, frost, insect residues, and birds' feces.

The invention relates to a urinal system (10), a water consumer system having such a urinal system, and a method for operating a urinal system. A urinal controller (8) of the urinal system has a data processing system (9) and/or is connected to a data processing system (9) which is designed to retrieve and/or receive and computationally evaluate data captured by at least one HF motion sensor (5) provided on a urinal bowl (1) and/or a urinal outlet (4) of the urinal system, and to recognize one of the following malfunctions based on the evaluated data and/or to initiate an action in order to avoid one of the fol-lowing malfunctions: that the urinal outlet is obstructed, and/or that there is a pressure fluctuation in a wastewater system connected to the urinal system, and/or that a fluid inlet (2) and/or an inlet valve (3) of the urinal system is malfunctioning, and/or that there is a failure of the HF motion sensor, and/or to recognize a predefined urinal usage situation and/or frequency of use on the basis of the evaluated data and, based on this, to adapt an opening time and/or an open-ing position and/or an opening frequency of the inlet valve to in a subsequent urinal flushing process.

Disclosed is a method for water saving by retrofitting an institutional plumbing fixture having a combination of an integral lavatory basin and a toilet bowel integrally attached thereto by inserting into the fixture a urinal-type collection receptacle having a water inlet opening on its top side and a water outlet opening on its bottom side; and fluidly interposing the receptacle via the inlet and outlet openings between the lavatory drain pipe and the drain trap provided for the plumbing fixture. Also disclosed is an institutional plumbing fixture retrofit for water saving, and a retrofit urinal-type receptacle.

A urinal module for installation in public toilets or private bathrooms, with the purpose of avoiding or reducing bad odors through the cooling of the contact surface of the urinal, where it impacts with the urine by the use of a cooling closed-circuit by direct expansion that includes a condensing unit and an electronic system of temperature control that are located in an external cabinet, separated from the urinal module. A centrally arranged water reservoir feeds the urinal module, each of which comprises a cooling streamer that leaves the condenser, enters through the back of the urinal closest to the cabinet and makes a journey through the inner back of the urinal to the point of contact with the lower reservoir of the same, resuming to the same point of entry of the urinal, from where it leaves, containing heated gas and returns to the compressor to achieve the closed-loop cooling effect. The temperature control of the urinal manages to form a thin ice protective layer, which will prevent the urine from vaporizing and, therefore, can be perceived by the sense of smell.
