The tank (101) having an overflow (107) conducting the water possibly present above the level of the overflow to the bowl (100), preferably at least via the first pipe (103). The reservoir (101) is associated with a housing (110) (located in the chamber 102, above the level of overflow, for example at least 3 cm above the level of the overflow) containing a fan or a turbine (11 ). The housing (110) is associated with a suction pipe (12) adapted to suck air or odors from the bowl (100) via at least partially the first pipe (103), and to a discharge pipe ( 13) adapted to discharge the air or odors discharged by the fan or the turbine (11) into the second discharge pipe (104) (in particular after the siphon 104A or at the level of the siphon 104A, but on the side of the pipe 105) and / or to the evacuation pipe (105).

The reservoir (101) comprises, in the vicinity of its bottom (101 A), an additional inner wall (101 B) defining with the outer wall of the reservoir (100), a chamber (112) distinct in the reservoir (101) or with respect to the tank (101), this separate chamber (112) directly communicating (a) with the first pipe (103) intended to bring water from the tank 101 into the bowl 100 when the flush (106) is in the open position (raised position ), and (b) with the fan or turbine housing (110) (11) via the suction line (12).

The substantially tube-shaped flush (106) also includes a means for forming an overflow (107) for evacuating fluid from the reservoir (102) to the chamber defined by the inner wall (101B) when the fluid level in the tank exceeds a predetermined level.

The suction pipe (12) or the casing (110) of the fan or turbine (11) in the vicinity of its suction inlet (110A) has a splash-proof means (113), said anti-splash means (113) being advantageously in the suction pipe (12), preferably at a level of more than 5 cm, advantageously more than 10 cm above the level of connection of the first pipe (103) to the chamber (112) defined by the inner wall (101B). The anti-splash means is for example a filter or a grid, or a series of grids, or a system comprising a series of baffles.

The fan or turbine housing (110) has an opening (114) associated with a valve or valve (115) movable between a closed position and an open position, said valve or valve (115) being associated with a means adapted to bring the valve or vlave (115) in the open position when the pressure inside the housing (110) is depressed relative to the pressure of the chamber 102, for example less than 150Pa, advantageously at least 100 °, in particular at least 50 Pa with respect to the pressure in the main chamber (102) of the water tank (101).

In the illustrated embodiment, the flush comprises a tube (106) having at its upper end (106E) an overflow opening (107) and means (108) forming a duct extending between the overflow opening (107) and a lower opening (108 A) located at a level of at least 1 cm, advantageously at least 2 cm below the overflow level (107), said duct (106) being adapted to allow the passage of fluid or from the tank (102) to the overflow opening (107) only via said lower opening (108 A). The overflow tube 106 is the flush tube controlled to move vertically V when actuating the flush.

The flush tube (106) is open at its upper end to form the overflow opening (107), while the conduit means to the overflow opening is a bell or a cap or lid (108). ) whose at least one side edge (109) at least partially surrounds the side wall of the tube (106) in the vicinity of the overflow (107).

The bell can be mounted movably on the flush tube (106), and is for example associated with at least one float (108F) so as to adapt the position of the bell (108) relative to the tube (106), depending on the level of liquid in the main tank (102). For example, bell 108 may close aperture 107 as long as the water level in reservoir 101 is below a predetermined level. As soon as the water level has reached a predetermined level, the bell is moved upwards so as not to close off the overflow opening 107. However, the water passes into the duct formed between the walls 109 of the bell and the tube 106, so as to form a means opposing the passage of air from the tank 101 via the tube 106, but allowing in case of too high level in the tank, the passage of water via the overflow 107.

Like the urinal of Figure 1, the toilet can be associated with an electronic nose sending a signal to a control means of the electric motor driving the fan or the turbine, in particular to vary the rotational speed of the motor based the signal emitted by the electronic nose, and / or a system for bringing at least one maintenance liquid to or into the cuvette or into the reservoir or into the chamber defined by the inner wall, and a presence detector adapted to emit or send a signal to the feeder system to control the amount of cleaning product brought into or to the bowl.

The electronic nose of the toilet is advantageously associated with the flush control system, to activate at least the release of two separate amounts of liquid to the bowl. The flush is for example movable between a closed position, a half open position and a fully open position. The electronic nose thus allows automatically, the release of a first amount of water (for example 3 liters) when the odor level is below a determined threshold (threshold corresponding to a level of odor of faeces), or a second quantity of water (for example 6 liters) greater than the first quantity of water when the odor level has exceeded a certain threshold (threshold corresponding to a level of faeces smell) faecal).

The electronic nose can also control the amount of maintenance product released in the bowl, in the tank or in the conduit leading the water from the tank to the bowl. For example, when the nose detects an odor level below a predetermined level (for example level corresponding to faecal excrement), the nose sends a signal to a control means of the maintenance product release device to release a first amount of product, in particular a first cleaning product, whereas when the nose detects an odor level higher than this predetermined level, the nose sends a signal to a control means of the product release device; maintenance to release a second quantity of maintenance product, a quantity greater than the first quantity, or to release a quantity of another maintenance product than the first cleaning product, advantageously in addition to the first quantity of maintenance product; first cleaning product.

The maintenance product supply system is advantageously located in the chamber 102 of the reservoir, while the odor detector is advantageously arranged in the suction channel 12 or at the level of the bowl. The urinal or the tank according to any one of the appended claims advantageously comprises a presence detection device, controlling or controlling the operation of the fan or the turbine, for example to control the operation as soon as a presence is detected and as long as the presence of a user is detected. This device then advantageously comprises a means that stops the operation of the fan or turbine, either as soon as the presence of a user is no longer detected, or after a certain delay or delay after the non-detection of a user. The invention also relates to an assembly comprising a urinal bowl or WC associated with a water tank, in particular an assembly as claimed in claims 12 to 18, said urinal or WC, the tank comprising or being associated a means for supplying a cleaning product controlled by a control system for controlling the supply or not of the maintenance product into the tank filled with water and / or for controlling the quantity of maintenance product supplied to the tank. The assembly is associated with a presence detector that sends a signal to the control system for bringing maintenance product into the tank as soon as the presence of a user or potential user is detected. Advantageously, once the amount of maintenance product is the desired quantity, the control system interrupts the supply of maintenance product. In this way the cleaning product retains its maximum efficiency when operating the flush.
