DESCRIPTION:
BRIEF SUMMARY
The present invention concerns a device that provides for the automatic disinfection of the pan and seat of a water-closet before it is at the disposal of a user.
At the present time, everybody has to make frequent use of public water-closets on various occasions in daily life, for example in places of work, when travelling (in transport vehicles such as trains, ships or planes, or in stations and airports, or else on the road, for example in car parks or gasoline stations), and in places of amusement and relaxation (such as theatres, restaurants etc.). For obvious reasons of hygiene, it is important for these users to be always assured of finding the sanitary fixtures of these public WCs, and especially the pans and seats of these WCs, perfectly clean and thoroughly disinfected even if, as if often the case, there is no staff available at all times to clean these fixtures.
Although, very often, these sanitary fixtures are kept clean, most of the time nothing is done to ensure that they are disinfected in a manner that can be verified.
It has been suggested that protective sheets, made of paper or cellulose compound and taking the shape of the folding seat, be used: the user could line the surface of the seat with these sheets and throw them away after use. This protective covering, however, has many disadvantages, firstly because it does not destroy any infectious germs that might be found on the seat and secondly because it concerns only the seat of the WC and not its pan, and also because it is not automatic in nature and may therefore be neglected or forgotten.
It has also been proposed that the interior of the folding lid of the WC seat be fitted with a ultraviolet lamp or tube whose electrical supply would be controlled automatically as soon as the lid is folded down on the seat, and whose radiation would be directed onto the surface of the pan and onto the seat, sterilizing these parts. Here again, however, the disadvantages entailed by this system are substantial, on the one hand because of the danger to the user from ultraviolet radiation and, on the other hand, because of the risks of deterioration due to the fragility of the ultraviolet lamps or tubes used.
The present invention is aimed at palliating the disadvantages of the known devices referred to above and, to this end, it proposes a device that is very simple to manufacture, and has a low cost price and high operating efficiency, enabling any user to obtain the automatic and total disinfection of the pans and seats of WCs fitted with this device, without having to perform any complicated or hazardous operation.
According to the invention, the folding lid, which is normally connected to the WC folding seat, it is designed to cover the said folding seat on all sides when in the folded position, and it has, suitably distributed over the inner surface and on its peripheral rim, dispersal holes connected by ducts, suitably placed within the said lid, to a tank containing a disinfectant product under pressure, with devices borne by the folding lid acting on the said tank to control, when the lid is in a totally folded position, the spraying process through the holes that disperse the streams of disinfectant which then reach the entire inner surface of the pan as well as the upper surface of the fixed seat and the upper and lower surfaces of the folding seat. A sealing joint, made of a product resistant to the effects of the disinfectant, is provided all along the edge of the lid and when the lid is folded, this joint works in close cooperation with the upper surface of the pan to prevent any of the product from seeping outwards.
Appropriately, the folding lid has, behind its pivoting axis, a box-shaped fixed element designed to receive the spraying control head of the tank containing the disinfectant, into which opens out one end of a flexible duct designed to fit the outlet hole of the said control head while the other end of this duct coincides, when the lid is folded, with the inlet hole of the ducts arranged inside the lid.
