- the end of the rod of the single-acting hydraulic cylinder 20 for pivotally actuating the washing head.
- this jack is articulated to the chassis 2 of the device.
- the supply of hydraulic fluid to the vè ⁇ n chamber, through the associated hydraulic circuit, leads, according to the mounting configuration presented in Figure 2, the retraction of the rod in the body and the pivoting of the head from its rest position to its operating position.
- the hydraulic circuit will include, as known, a valve of the type, for example, two ways three orifices piloted or not placed in series on the supply chamber of the jack, this valve being controlled by the control push-button actuated by the user to start the wash cycle. This button is located on the device folder.
- a return member 21 is provided, consisting of a coil spring.
- This spring 21 is fixed on the one hand to the arm 19 and on the other hand to the chassis 2.
- the hydraulic circuit of the hydraulic cylinder is connected to the water distribution network, the latter constituting the pressure source.
- the motor member for actuating the pivoting head is constituted by an electric actuator or more generally by any suitable type of electric motor.
- the washing head 18 consists of a housing in which the washing nozzle 22 of the inner face of the bowl are arranged, the washing nozzle 23 of the seat 6 and the drying nozzle 24 of the latter. These three nozzles are fixed to the bottom wall of the housing and come into correspondence with openings made in the latter.
- the first nozzle 22 for washing the internal surface of the bowl i is located in front of the seat 6, above the said surface, while the nozzles 23 and 24 for washing and drying the seat 6 are located above the latter, the nozzle 23 for washing the seat 6, considering the direction of rotation of the bowl 1, being arranged upstream of the drying nozzle 2 4-
- the first nozzle 22, when the head 18 is in the position of use is oriented towards the upper part of the internal surface of the bowl 1 so that the impact of the jet of fluid delivered by said nozzle 22, occurs in this part, which allows, the bowl being rotated, to sweep the entire internal surface by the fluid jet.
- the nozzles 23 and 24 for washing and drying the seat 6 of the bowl are oriented towards the latter.
- the washing nozzle 23 of the seat is preferably oriented towards the center line of the latter so that the jet of washing fluid, by striking the seat through said middle zone is distributed over the seat 6 on either side said line.
- part of the washing fluid flows into the bowl 1, the other part, that directed towards the vertical rim 7 of the seat, flows from this rim, towards the outside of the bowl where it is recovered by a receptacle 25 in the form of a tray.
- This tank by its front part is arranged under the vertical rim 7 of the seat 6.
- This tank 25 preferably arranged in rear tilt, is connected to a pipe (not shown) for discharging the recovered washing fluid, said pipe being connected to the network waste water collector via u siDhon.
- the drying nozzle 24 covers the entire width of the seat and has a drying fluid outlet mouth following the outline of a rectangle.
- the axis of the jet exiting from this nozzle is inclined relative to the normal to this surface and towards the axis of the bowl so that said jet strikes the seat with angle of incidence and drives towards the bowl the washing fluid present on the seat.
- the three washing and drying nozzles are each connected, via flexible pipes penetrating the head, to their respective system for supplying washing or drying fluid.
- the system for supplying the first washing nozzle 22 is constituted by a high pressure pump to the outlet orifice to which the flexible supply line for the nozzle 22 is connected.
- the inlet for the pump is connected via a line of the supply system to a source of pressurized washing fluid such as water.
- This source can be constituted by a water tank with a capacity of a few liters comprising automatic means for filling with water and stopping the filling when the maximum filling level is reached.
- the high-pressure pump is connected directly to the water distribution network.
- the high pressure pump makes it possible, at the level of the first nozzle, to obtain a jet of pressurized water, and advantageously the section of the outlet orifice of the bus 22 is large, which makes it possible to obtain 'an important challenge.
- a jet of water, under high pressure and flow high, in combination with the rotation of the bowl ensures a complete washing of the internal surface of the latter without residual traces, also ensures the guiding of materials towards the neck of the bowl and finally ensures their flushing first towards the siphon 4, then to the collecting line 3.
- the supply system of the second nozzle comprises a high pressure pump connected by its outlet orifice to the flexible supply pipe of the second nozzle. Through its inlet orifice, this pump can be connected either to the water distribution network or to a small capacity auxiliary tank with means for automatically filling with water and stopping the filling when the maximum filling level is achieved.
- the high pressure pump allows the level of the second nozzle to form a jet of water under high pressure. The section of the outlet orifice of this second nozzle being small, the flow rate of this jet is low, the need for water for cleaning the seat being less than that required for cleaning the bowl.
- the drying fluid used is air and the supply system comprises a fan member connected by its outlet mouth to the supply pipe of the drying nozzle 24, said fan member also comprising a mouth inlet through which air is drawn in.
- the supply systems for washing fluid and drying fluid are associated with controlled dispensing metering members, not shown, intended to incorporate into the washing fluid and the drying fluid, disinfection products, bactericides, deodorants and other cleaning products and / or adjuvants, and this in metered and controlled quantities.
- These products will be contained in tanks supported by the chassis of the device and connected via pipes to the corresponding dispensing metering members which will be in contact via pipes with the washing fluid and washing fluid supply systems. drying.
- the device can also be equipped with several position sensors to deliver to the programmable controller a signal representative of the position of the cleaning head.
- a tachometer known per se may be associated with the bowl 1. This tachometer body will deliver to the programmable controller a signal representative of the number of revolutions made by the bowl, which will control the stopping of the rotation. by deactivation of the motor 13, when the required number of revolutions has been reached.
- the rev counter can advantageously be replaced by an electric timing circuit.
- the various electric motors equipping the device such as the electric motor 13 for actuating the rotating bowl 1, the electric motors equipping the two high-pressure pumps, the electric motor for activating the fan and the electric members of dispenser dosers will be activated or disabled, that is, energized or de-energized electrical by electro-mechanical or electronic relays controlled in the direction of activation and then deactivation by electrical signals emitted by the programmable controller on the one hand from a preset program and on the other hand from the logical state of the different organs.
- the control button from which the cycle is triggered is advantageously constituted by the flushing operation button fitted to the reservoir for the water supply system of the first nozzle 22.
- This control button can actuate an electric sensor by which an electrical signal for the start of the wash cycle will be delivered to the programmable controller.
- control button or flush button actuates the hydraulic circuit valve of jack 20 in the direction of supply to its chamber.
- This arrangement is particularly advantageous since it allows, despite the absence of electrical energy due, for example, to an electrical cut-off, the forward movement of the washing head and the flushing action by emptying of the reservoir associated with the supply system of the first nozzle 22.
- valve of the hydraulic circuit of the hydraulic cylinder 20 will be brought back to the cut-off position of the power supply and of the cylinder chamber by all hydraulic automation circuits, known to those skilled in the art.
