Abstract

Sont divulgués des toilettes sèches à déviation d'urine et leur procédé d'utilisation. Les présentes toilettes sèches à déviation d'urine sont obtenues par ajout d'un capteur infrarouge et d'un générateur de mousse (1) à un corps de toilettes sèches à déviation d'urine. Le capteur infrarouge démarre le générateur de mousse (1) avant utilisation, et une solution moussante mélangée contenue dans un réservoir de solution dudit générateur (1) forme de la mousse (6) sous l'action d'un gaz. La mousse (6) recouvre et mouille la surface interne de la cuvette du corps de toilettes sèches à déviation d'urine, une partie de la mousse (6) pénétrant dans une ouverture de tube de collecte de matières fécales (2) pour recouvrir un tas d'excréments se trouvant au fond, de sorte à dissimuler visuellement le tas d'excréments tout en réduisant encore l'échappement d'odeurs et l'entrée de particules fines provenant d'une fosse de stockage de matières fécales dans une salle de toilettes. Le reste de la mousse (6) pénètre dans une ouverture de tube de collecte d'urine (3), de sorte que l'échappement d'odeurs singulières telles que le gaz ammoniac peut être réduit. Ainsi, les problèmes tels que la saleté des toilettes, les odeurs singulières, l'inconfort visuel, la suspension de particules en intérieur et analogues peuvent être résolus efficacement.
