Abstract

La présente invention concerne une structure de toilettes qui comprend : une partie de rinçage inférieure et une partie de rinçage supérieure. La partie de rinçage inférieure comprend une partie d'extension avant, une partie d'extension arrière disposée à l'opposé de la partie d'extension avant, et une partie de siphonnement La partie d'extension avant comprend un tuyau d'extension qui reçoit de l'eau, scelle l'eau et est disposée au milieu de la partie d'extension avant et de la partie d'extension arrière La partie de siphonnement comprend une partie de collecte de saleté disposée au-dessous d'une sortie d'eau d'une buse inférieure et d'un bord d'orifice de siphonnement. La hauteur de la partie de collecte de saleté est inférieure à la hauteur d'un angle convexe et d'une paroi d'extension avant, et l'extrémité de la partie de collecte de saleté à l'opposé de la buse inférieure est pourvue de l'orifice de siphonnement. Dans la présente invention, la partie de collecte de saleté et une paroi d'extension arrière sont déplacées vers une position plus en arrière et une position plus basse, de sorte que la saleté évacuée par les utilisateurs tombe sur le côté droit d'une ligne tangente verticale d'un bord inférieur de paroi arrière, c'est-à-dire la partie la plus basse de la totalité des toilettes, ce qui augmente la quantité d'espace pour contenir la saleté. Lorsque la saleté est rincée, les impuretés et l'écoulement d'eau ont une grande quantité d'espace pour le mouvement, de sorte que les phénomènes de blocage et d'éclaboussement ne se produisent pas, et un fort effet de siphonnement est généré, qui peut s'adapter à une pression d'alimentation en eau plus basse, et améliore le côté pratique des toilettes.
