Abstract

L'invention concerne un WC à faible niveau d'eau. Selon l'invention, un corps de WC (1) est pourvu d'un réservoir de stockage d'eau (11), d'une cuvette de WC (12), d'un canal de distribution d'eau de rinçage en forme d'anneau (13) et un tuyau de distribution d'eau de pulvérisation (14) ; le réservoir de stockage d'eau (11) est pourvu d'un dispositif d'entrée d'eau (2), d'une soupape de vidange (3) et d'un composant d'alimentation en eau de rinçage (4) en forme d'anneau, une extrémité du composant d'alimentation en eau de rinçage (4) en forme d'anneau étant connectée au canal de distribution d'eau de rinçage en forme d'anneau (13), et l'autre extrémité étant connectée au dispositif d'entrée d'eau (2) ; le composant d'alimentation en eau de rinçage (4) en forme d'anneau est pourvu d'un mécanisme d'éjection connecté au réservoir de stockage d'eau (11), et lorsque l'eau s'écoule depuis le dispositif d'entrée d'eau (2) vers le canal d'alimentation en eau de rinçage (13) en forme d'anneau, une pression négative est générée dans le mécanisme d'éjection de telle sorte que l'eau stockée dans le réservoir de stockage d'eau (11) soit aspirée vers le canal d'alimentation en eau de rinçage (13) en forme d'anneau ; le tuyau d'alimentation en eau de pulvérisation (14) est disposé indépendamment dans le corps de WC (1), et le tuyau d'alimentation en eau de pulvérisation (14) est seulement pourvu de deux ouvertures, à savoir une entrée d'eau connectée à la sortie de la soupape de vidange (3) et une ouverture de pulvérisation d'eau (141) connectée au fond de la cuvette de WC (12) ; dans un état sans vidange, la soupape de vidange (3) scelle l'entrée d'eau du tuyau d'alimentation en eau de pulvérisation (14) pour isoler par rapport à l'air extérieur l'extrémité du tuyau d'alimentation en eau de pulvérisation (14) où se trouve l'entrée d'eau.
