Definitions

• vacuum sewer device comprising a material discharge element in the sewer, for example a toilet bowl connected to a vacuum sewer by a normally closed sewer valve, a device The control valve for the sewer valve and an air inlet duct which can admit air into the vacuum sewer separately from the discharge element to the sewer.
• the air inlet duct has an air inlet valve which controls the air inlet to the vacuum sewer.
• the air inlet valve opens in time relation to the opening of the sewer valve and closes after the closure of the sewer valve. This device makes it possible to obtain a reduced noise level.
• This invention has its place in all domestic, industrial or other homes, where there is an economy to be realized.
• FR-A-2.641.561 Improvement in toilet bowls with a vacuum blower characterized in that the vacuum blower is rotated by means of a hydraulic turbine powered by pressurized water from the distribution network . The water which comes out of the turbine body is used to rinse the bowl through the pipe.
• devices are put in depression of the bowl, in general, it is a question of sucking bad odors.
• the present invention is a removable stale air extraction method using a set of accessories consisting of at least one nozzle with a flat section interposed between the toilet bowl and the flap and at least one flexible connection hose with a high extraction mouth of a technical part thus causing a suction flow controlled by the latter.
• a cabinet comprising a lid, a seat and a bowl which becomes watertight when the lid is closed and which has an inlet for rinsing liquid, a watertight element in the form of a ring, which must be compressed between the cover and the seat or between the seat and the bowl, being housed in an endless notch located in one of the two said members, the notch having a base and an internal wall which delimit a recess, which is of cross section of cuneiform type, the cross section of the element being practically quadrilateral, this quadrilateral having an acute angle which is placed in the recess, the opposite corner having a flexible lip situated in the diagonal of the quadrilateral and projecting from one side of the 'element, so as to be able to engage the other of the two so-called me ⁇ res, a pump being provided to evacuate the excrement from the bowl and to create a partial vacuum inside that i must cause the spontaneous entry of the rinse aid by the arrival of liquid
• this patent describes the use of a vacuum in a toilet seat.
• the purpose of this patent is to reduce noise, reduce odors and this by creating this vacuum.
• the vacuum is created by the use of the suitable material in the seat. Holes let out deodorant products. There is no overpressure, no hermetic closure, no action to improve the evacuation of water or to reduce water consumption.
• the toilet according to the invention tends to reduce the consumption of water by modifying, in current installations, only the flap and / or the seat.
• the WC is of the type comprising a bowl, a flush, a siphon, a flap and possibly a seat, characterized in that the release of the column of rinsing water puts the bowl under pressure, the flap and possibly the seat are provided with means which seal the closure of the seat flap on the edge of the bowl, only when said bowl is overpressure and said flap comprises a means for blocking its opening in the closed airtight position so as to resist said overpressure.
• the locking means in the closed position of the flap resides in its weight which is greater than the weight of the rinse water column, so as not to rise when the rinse water column is released in the bowl and thus resist overpressure.
• the locking means of the flap is a hook which keeps the flap in the airtight closed position.
• the flap is airtight, overpressure of the bowl, by means of a seal ' which. cooperates with the edge of the bowl or seat.
• the seat also has a ( gasket which seals, overpressure of the bowl, between the underside of the seat and the edge of the bowl.
• Figure 1 is a schematic view of a traditional toilet in which the flap and the seat are not hermetically closed.
• Figure 2 is a schematic view of a W.C with a flap and an airtight seat when closed and folded down on the bowl.
• the classic WC is composed of: a bowl 1, a siphon 2, a flushing flush 3, a seat 4, and a flap 5.
• This conventional flap 5 and its seat 4 are not provided with means ensuring a hermetic closure upon opening of the valve 6 of the flushing flush 3, the flushing water 7 must reach a certain level of height in the bowl 1 above the level of the siphon 2 to initiate the evacuation of sewage.
• the valve water swirls at the bottom of the bowl 1 and all of the valve water is not always discharged.
• This type of classic WC works with an average of ten liters of water.
• the WC according to the invention can operate with only four liters of water.
• the toilet seat and possibly the seat, if there is one, must ensure a hermetic seal when closed, folded over the edge of the bowl. Only the seat must be modified and possibly the seat. All the rest of the classic toilet can be kept. It then suffices to reduce the volume of rinsing water contained in the flush, for example:
• the flap 9 and the seat 10 are respectively provided with means such as seals 11, 12, which ensure the seal when the flap 9 and the seat 10 are closed.
• the volume of flushing water 7 creates an overpressure down to the bowl 1 which is closed hermetically, thanks to the flap 9 and the waterproof seat 10, causes, before said rinsing water 7 reaches the bottom of the bowl 1, the evacuation of a large part of the valve water contained at the bottom of the bowl 1 and this, without waiting for the water of rinse 7 does not raise the level of siphon 2 to start its evacuation.
• the valve water is evacuated more quickly, thus requiring much less rinsing water, see arrows F2, F3.
