[0032] SUMMARY: These detailed drawings provide a visual narrative of the combined toilet and urinal invention, showcasing both the rim and rimless options with alternative flush systems for enhanced cleaning of the urinal extension along with the integration of shaped seat and lid elements.DETAILED DESCRIPTION OF THE INVENTION
[0033] The invention resides in the technical field of sanitary fixtures and plumbing infrastructure, specifically, toilet bowl and urinal design with a semi-circular cup-shaped addition to create a dual-purpose toilet-urinal.
[0034] The invention introduces an enhancement to traditional toilet fixtures addressing longstanding challenges in hygiene and user comfort. By extending the bowl design with a semi-circular cup-shaped extension, the invention creates a dual-purpose toilet-urinal.
[0035] This innovative approach not only effectively captures and contains urine drips, preventing floor spillage, but also facilitates a more comfortable user experience.
[0036] The invention enables users who stand to urinate, to stand closer to the bowl with legs on either side of the protruding cup-shaped extension, reducing the risk of unintentional spills during urination. Additionally, the design minimizes the chance of genital contact with the bowl and splashes during seated urination and urination while defecating adding an extra layer of user comfort and hygiene.
[0037] The urinal extension design also allows the user better access to self-care hygiene when seated.
[0038] Versatility is a key aspect of the invention, offering the option for manufacturing in stainless steel or traditional ceramic materials to suit diverse preferences. The integrated urinal feature contributes to improved health and hygiene, while the design's compatibility with existing plumbing infrastructure ensures seamless replacement.
[0039] Prior art primarily encompasses traditional toilet designs typically with standard oval bowl configurations. This art includes various attempts to address these issues, such as anti-splash technologies and modifications to the bowl shape. However, these solutions typically focus on mitigating urine splash from the bowl itself rather than preventing the more frequent spillage onto the floor.
[0040] Prior art also includes separate urinals in public facilities, necessitating dedicated spaces and plumbing. These solutions are often impractical in mixed-gender facilities, which are becoming increasingly common, or residential settings, where space constraints and additional plumbing complexities pose extra cost.Embodiment 1: Integrated Design with Shaped Seat and Lid
[0041] This embodiment features an enhanced toilet-urinal hybrid with an extended bowl and a semi-circular cup-shaped extension at the front. The seat and lid are uniquely shaped to match the contours of the extended bowl, providing a seamless and ergonomic fit.
[0042] This design ensures optimal user comfort and minimises genital contact with the bowl and splashes during both seated urination and urination while defecating. The urinal extension design also allows the user better access for self-care hygiene when seated.Embodiment 2: Proximity-Optimized Configuration
[0043] In this embodiment, the semi-circular cup-shaped extension is strategically positioned to enable users, who urinate standing, to stand closer to the bowl with legs on either side of the bowl. This embodiment prioritizes user comfort and addresses common spillage challenges associated with conventional toilet designs.Embodiment 3: Cleaning-Enhanced Flush System
[0044] This embodiment for the rimless toilet urinal combination includes a two-deflector flush system with a second deflector at the start urinal extension to deflect the flush water around the bowl extension. This design ensures thorough cleaning in the urinal extension area, contributing to improved hygiene.Embodiment 4: Material Adaptability
[0045] A variant embodiment emphasizes the adaptability of the invention with alternative manufacturing materials and a choice of rim or rimless options. The invention can be manufactured in stainless steel or traditional ceramic, providing flexibility to suit diverse settings such as homes, public venues, commercial use, portable loos, outdoor concerts, stadiums and mixed gender public lavatory facilities to effectively mitigate the common problem of urine spillage.
