Definitions

  • the present invention refers to a security device for toilets, that prevents the water from the toilet deposit to return to the mains if a pressure drop is produced in the water feeding.
  • the toilets comprise a water deposit where the water that is used to be flushed to the toilet bowl is stored, so that the wastes inside the bowl are sent to the drainage system.
  • the water inside the toilet deposit has a classification according to the regulations, and the water inside the toilet bowl has a different classification, according to the same regulations, and it is necessary to prevent these waters to return to the water mains in case of a breakdown for sanitary reasons.
  • the holder of the present application is currently working on the design of a toilet whose deposit is placed at a lower level than the rim of the toilet bowl, and it directs the water from said deposit to the bowl introducing pressurized air inside said deposit, so that the object of the present invention is a security device permitting the toilet to fulfill the current regulations.
  • the security device for toilets of the present invention comprises a water inlet from the mains, defining a nominal value of water inside the water deposit of a toilet, and it is characterized in that it comprises a tank housed inside or placed above said water deposit, said tank being provided with a valve to permit the water communication between said tank and said deposit to be opened or closed, said valve being associated with flushing means, so that when said flushing means are on operation, the valve closes the communication between said tank and said deposit.
  • said valve can be mechanical or electric.
  • said flushing means is a compressor, even though it could be any suitable flushing means.
  • Said water inlet is advantageously placed at a height higher than a critical water level, said critical water level being above an overflow opening of said tank.
  • said valve comprises a ball that closes the water communication between said tank and said deposit when the flushing means is operated.
  • the security device for toilets of the present invention ensures that the water inside the toilet tank is prevented to return to the water mains in the case of a pressure drop in the water mains, because before this happens, the water will overflow over the upper part of the toilet bowl.
  • Fig. 1 is a diagrammatical elevation view of the security device of the present invention applied in a toilet.
  • the security device of the present invention is applied in a toilet, which comprises a bowl 1 and a deposit 2, which stores the water that will be flushed to the bowl 1 by flushing means 3, e.g. a compressor or any suitable flushing means.
  • flushing means e.g. a compressor or any suitable flushing means.
  • This deposit 2 can be placed at the same height or below said toilet bowl 1, behind it, around it or even fitted in a wall.
  • a water nominal level is defined, indicated by letter N, corresponding to the water level during the normal operation of the toilet.
  • the security device comprises a tank 4 placed inside said deposit 2, as shown in Fig. 1 , o above said deposit 2. It is important to place the bottom of said tank 4 at a higher lever than the bottom of said deposit 2. Said tank 4 is communicated with the deposit 2 by a valve 5.
  • Said valve 5 can be any suitable valve, e.g. a mechanical valve or an electric valve.
  • said valve 5 comprises a ball that closes the water communication between said tank 4 and said deposit 2 when the flushing means 3 is operated.
  • valve 5 When the toilet is not flushing, the valve 5 allows the water to flow between the deposit 2 and the tank 4, so that the water level inside the tank 4 and inside the deposit 2 will be the same.
  • Said valve 5 is associated with said flushing means 6 so that when said flushing means 6 are on operation, the valve 5 is closed, not permitting the passage of water from the deposit 2 to the tank 4.
  • the toilet also comprises a water level detector 6 that is placed inside said tank 4.
  • This water level detector 6 is e.g. a buoy vertically movable along a guide 7, even though it could be any suitable level detector.
  • a critical level is defined, indicated in Fig. 1 by letter C, so that the water from the tank 4 could not reach the water mains because the water inlet 8 is always at a level (the inlet level I indicated in Fig. 1 ) higher than this level C.
  • overflow opening 9 is always at a level lower than the critical level, so that there is no possibility for the water to return the water mains, as it is required by the regulations.
  • the security device of the present invention it is possible to meet the regulations for toilets independently from the position of the water deposit 4 of the toilet, even if this deposit 4 is placed at the same level or below the toilet bowl 1.
