Water-closet construction

Claim 2

A toilet comprising a bowl an evacuation pipe associated with said bowl, said evacuation pipe comprising an upwardly raised part enabling a reserve of water to be maintained in said bowl, the reserve being sufficient to ensure the evacuation of the waste matter without more water having to be added, evacuation means situated in the transition zone between the bottom of the bowl and the evacuation pipe, said evacuation means being adapted to cause the reserve of water and the waste matter to be discharged towards the evacuation pipe, control member likely to be actuated by the user and adapted to control the action of said evacuation means, water inlet adapted to discharge fresh water into said bowl closure valve associated with said water inlet detection means adapted to check the level of the water into said bowl and remote control means interconnecting said detection means and said closure valve and adapted to command the flow of fresh water through said closure valve as long as the level of the wateR into said bowl is under a predetermined height.

Claim 3

A toilet according to claim 1 wherein it comprises further a column the base of which is in communication with the bottom of the bowl, the liquid contained in the bowl thus being placed in communication with the liquid penetrating in said column, a manostat placed at the upper part of said column, said manostat being sensitive to the changes in pressure produced in the gaseous phase located in the upper part of the column further to the drop or rise in the level of water in this latter, an electrical relay associated with said manostat, a first electrovalve forming said closure valve, electrical circuit means connecting said relay and said first electrovalve, so that the drop in pressure in the detection column corresponding to the drop in the level of water in the bowl causes the opening of the first electrovalve and allows the fresh water to be supplied in the bowl, the rise in pressure detected by the manostat at a determined value further to the rise of water in the detection column and the bowl causes the opening of the electrical feed circuit of said first electrovalve so as to close it and to stop the supply of fresh water to the bowl

Claim 4

A toilet according to claim 1 wherein the bowl comprises an auxiliary water inlet opening out slightly below the level of the water in reserve in the bowl, this auxiliary water inlet opening into the bowl in a substantially tangential direction, being adapted to initiate a peripheral stream along the inside wall of said bowl, so as to facilitate the evacuation of the waste matter suspended in the water.

Claim 5

A toilet according to claim 1, wherein the upwardly raised part of the evacuation pipe is associated with an S-bend extending said upwardly raised part so as to form a siphon, the lower level of the siphon being sufficiently high to enable a reserve of water to be maintained in the bowl, the water evacuation means being constituted by a water discharge nozzle situated at the base of said upwardly raised part of the evacuation pipe and adapted to direct a jet of water substantially in the axis of said raised part, a water feed pipe connecting said nozzle to the main water supply, valve means controling the feed of water to the nozzle and the discharge of water by said nozzle being adapted to raise the level of water in said upward part of the evacuation pipe up to the level of said siphon and so to initiate the suction phenomenon of the siphon and to cause the complete evacuation of the reserve water from the bowl.

Claim 6

A toilet according to claim 4 wherein said valve means controlling the feed of water to the nozzle is a second electrovalve, the control member likely to be actuated by the user to control the action of the evacuation means is a contactor of the push-button type, the toilet comprising further electrical circuit means interconnecting said contactor and said second electrovalve, the action of the user on the contactor being capable of opening the electrovalve and allowing a jet of additional water to be discharged through the nozzle, thus allowing the suction phenomenon of the siphon to be initiated and the reserve water to be evacuated from the bowl.

Claim 7

A toilet according to claim 3, wherein it comprises a third electrovalve connecting said auxiliary water inlet to the water supply pipe, this third electrovalve being coupled to the second electrovalve controlling the discharge of the nozzle, said second and third electrovalves being subjected to the action of said control member.

Claim 8

A toilet according to claim 6, wherein said control member is situated behind the seat and it comprises an electrical contactor of the push-button type, adapted to be put in active position by the pressure exerted on the push-button by the user and ensuring the closure of the circuit of the second and third electrovalves thus controlling the feed of water to the nozzle initiating the siphon phenomenon, and to the auxiliary water inLet within the bowl.

Claim 9

A toilet according to claim 1 wherein said evacuation means are constituted by an electrical grinder adapted to reduce the suspended waste matter in the reserve water to the fluid state and to evacuate the mixture through the evacuation pipe, a time switch device adapted to control the actuation of said grinder and circuit means connecting said time switch device to said control members.
