  • lavatories consisting of a small chamber which contains the water closet, which have appliances for the automatic cleansing and disinfecting of the entire lavatory after each time it is used.
  • Such lavatories are very expensive, requiring, furthermore, the provision of an appropriate structure to house the water closet, which needs to be able to be completely sealed during the cleansing and disinfecting cycle.
  • the prior art also involves a water closet with a device, connected to the water plunger button, that has the function of substituting the seat on the bowl with another clean and disinfected one, each time the said button is activated. This device is bulky and costly and needs to be used in conjunction with another device that has the function of cleansing and disinfecting the substituted lavatory seats.
  • the invention resolves the said technical problem by adopting a device consisting of a cover divided into two parts: a lower part fixed removably to the upper rim of the bowl and on whose internal surface sits the seat, and an upper part made to sit over and seal the lower part and which can be lifted up from it; in said upper part there being a pair of closed circuit channels with holes on the underside, preferably of capillary section; the said channels being supplied with the cleansing and disinfecting fluid for the seat, or with hot air, via a three-way valve, with two inlets and one outlet, which is in turn supplied with the cleansing and disinfecting fluid, for example by means of a pump, and with hot air, for example by means of a ventilator; the device possibly having an actuator with the function of lowering and lifting the said upper part at the beginning and at the end of each cleansing and disinfection cycle.
  • the advantages offered by the invention are: simplicity of manufacture and reduced cost of the apparatus as described; maximum certainty of the hygiene of the water closet; low operating costs; possibility of fitting the apparatus to any

Abstract

Le dispositif pour nettoyer et désinfecter les sièges de toilettes est conçu pour obtenir un nettoyage et une désinfection corrects du siège après chaque utilisation. Le dispositif consiste en un couvercle (2) divisé en deux parties: une partie inférieure (3) fixée d'une manière amovible au bord supérieur de la cuvette (1) et sur la surface interne de laquelle le siège (30) est en appui, et une partie supérieure (4) conçue pour venir se placer et fermer d'une manière étanche ladite partie inférieure (3) et pour être levée en pivotant par rapport à elle. Dans cette partie supérieure (4), il est prévu une paire de canaux en circuits fermés (26, 27) avec des trous (29) sur le côté inférieur, de préférence avec une section capillaire, pour répartir sur le siège (30) le fluide nettoyant et désinfectant, ou encore de l'air chaud.
