Definitions

  • the present invention relates to a steerable nozzle intended to send water into one or the other of a plurality of detergent tanks of a washing machine.
  • one solenoid valve is used to send water to the tanks.
  • the solenoid valves are expensive.
  • the use of an adjustable nozzle to send water into the tanks allows the use of a single solenoid valve for any number of tanks.
  • a conventional steerable nozzle is coupled to a feeler which is biased by a spring towards a circular cam driven in rotation by the programmer of the washing machine.
  • the cam includes sectors with different radii to orient the nozzle towards the different tanks.
  • the cam must be provided with ramps for passing from one sector to a sector of larger radius.
  • a disadvantage of these ramps is that the programmer cannot perform program steps while crossing the ramps. This drawback is all the more serious since the ramps must be of gentle slope so that the programmer does not have to exert too great a torque to move the nozzle, this significant torque being able in the long run to deteriorate the programmer, the cam, or the nozzle to cam coupling system.
  • German patent application 1,710,566 describes a nozzle device avoiding this drawback.
  • This device uses a bellows system inflated by the pressure of the water going to the nozzle to move the nozzle.
  • the device is however particularly bulky to obtain an adequate clearance of the nozzle.
  • An object of the present invention is to provide a particularly space-saving steerable nozzle device which can function correctly with a cam without ramps.
  • a spring is arranged so as to urge the aforementioned probe to a rest position remote from the cam.
  • a hydraulic turbine exploiting the energy of the fluid flowing towards the nozzle, is provided to move the nozzle by a gear against the force exerted by the spring. When the turbine is actuated, the nozzle rotates against the force of the spring until the probe comes into abutment against a sector of the cam.
  • the present invention relates more particularly to a device with a nozzle orientable about an axis perpendicular to the nozzle, comprising a cam for determining by corresponding sectors several rotational positions of the nozzle.
  • An elastic means is arranged so as to urge the nozzle towards a rest position of non-cooperation with the cam.
  • a hydraulic motor exploits the power of the fluid flowing towards the nozzle to drive the nozzle against the elastic means towards a position of cooperation with the cam.
  • the hydraulic motor comprises a turbine driven by the fluid flowing towards the nozzle and driving the nozzle in rotation by a gear.
  • a feeler lever is coupled to the nozzle and cooperates with the cam to determine the positions of the nozzle.
  • the lever is coupled to a pulley of the nozzle by a cable.
  • the device comprises a deflection piece cooperating with the nozzle for deflecting the jet supplied by the nozzle if the latter is not at a position determined by a sector of the cam.
  • said lever is coupled to the deflection piece which is freely articulated relative to the axis of rotation of the nozzle and resiliently biased towards a position for deflecting the jet, against said elastic means.
  • the lever is coupled by a cable to a pulley free to rotate relative to the nozzle around said axis, the deflection piece being integral with the pulley and urged towards the deflection position by a spring pressing between a finger of the nozzle and a stop of the deflection piece.
  • a nozzle orientable around a horizontal axis A is coupled to a hydraulic motor 12.
  • a pipe 14 supplies the motor 12 with water via a solenoid valve 16.
  • the motor 12 is such that , when powered by the solenoid valve 16, it drives the nozzle 10 clockwise in the figures.
  • the nozzle is provided with a pulley 10-1 in which is fixed a cable 18 tending, under the action of a spring 20, to move the nozzle 10 anti-clockwise.
  • the cable 18 is fixed between the pulley 10-1 and the free end of a lever 22 articulated at the other end on the frame of the washing machine.
  • the aforementioned spring 20 is fixed between the free end of the lever 22 and the frame of the washing machine so as to tension the cable 18.
  • the nozzle 10 is in a rest position where the motor 12 is not supplied and where the spring 20 applies the lever 22 against a stop 24 of the frame of the washing machine.
  • Lever 22 includes a feeler 22-1 on the opposite side of the stop 24, which is intended to cooperate with a cam 26 rotated by the programmer (not shown) of the washing machine.
  • the cam 26 comprises, for example, zones with four different radii to define the position of the nozzle 10 relative to four tanks 28 of detergents.
  • the tanks 28 are arranged under the nozzle 10 and aligned in the direction of scanning of the nozzle.
  • the walls of the tanks 28 may include guide portions 28-1 arranged radially with respect to the axis A of rotation of the nozzle.
  • the nozzle 10 In the rest position of FIG. 1A, the nozzle 10 is not oriented towards one of the tanks 28. This is due to the fact that there is a need in the rest position for a clearance between the probe 22 -1 and a sector of larger radius of the cam 26 so that the cam 26 can rotate freely.
  • a sector of larger radius of the cam 26 corresponds to the first tank towards which the nozzle 10 must be oriented, the right tank in the figures.
  • a sector of corresponding radius is located opposite the probe 22-1, which is determined by the programmer, and the solenoid valve 16 is open. Then, the hydraulic motor 12 is supplied and drives the nozzle 10 clockwise. The nozzle 10 drives, via the cable 18, the lever 22 in a clockwise direction against the spring 20, until the probe 22-1 abuts against the cam 26 .
  • FIG. 1B represents the position of the elements of FIG. 1A when the probe 22-1 is in abutment against the cam 26.
  • the nozzle 10 is located opposite the tank 28 on the right corresponding to a larger sector radius of the cam. If the solenoid valve is cut, the elements return to the position of the Figure 1A. And the cam 26 can rotate freely so as to match with the probe 22-1 a sector of different radius corresponding to another tank 28.
  • the nozzle 10 begins by sending a jet of water outside the tanks 28.
  • the position to be reached corresponds to one from the last tanks, the nozzle sends water to the intermediate tanks during its tilting. This is not annoying in certain cases because, on the one hand, the tanks 28, the motor 12 and the nozzle 10 are arranged in the tank of the washing machine, and therefore the water passing next to the tanks is recovered in the tank; on the other hand, the tanks are intended to be emptied sequentially, that is to say that, when one wants to empty a given tank, the previous tanks have already been emptied and it is not a problem that these receive water.
  • FIGS. 3A and 3B described later, makes it possible to avoid sending water into intermediate tanks.
  • FIG. 2A represents a side view in section of an embodiment of hydraulic motor 12 and FIG. 2B represents a view in section along the line II-II of FIG. 2A.
  • the nozzle 10 is formed by a tube bent at 90 °. This tube has a part radial to the axis A, forming the outlet of the nozzle, and an axial part to which the pulley 10-1 mentioned above is fixed.
  • the motor comprises a plastic housing 12, a wall of which, superior to FIG. 2A, is crossed by the axial part of the nozzle 10.
  • This axial part comprises, inside the housing, a toothed flange 10-2 meshing with a pinion 30.
  • the pinion 30 is integral with a toothed disc 30-1 meshing with a pinion 32.
  • the pinion 32 is integral with a blade turbine 34 best seen in Figure 2B.
  • the water coming from the duct 14 arrives, as shown in FIG. 2B, tangentially to the turbine 34.
  • the housing 12 has at the turbine 34 a cylindrical shape of slightly larger diameter larger than that of the turbine.
  • the upper part of the turbine 34, in FIG. 2A, is open so that the water driving the turbine can be evacuated and come out through the nozzle 10.
  • the housing 12 does not need to be sealed because the assembly of the nozzle 10 and the motor is located in the tank of the washing machine.
  • FIGS. 3A and 3B represent two positions of an embodiment of a device with an adjustable nozzle according to the invention, making it possible to avoid sending water into tanks which are in the path of a tank to be reached by the nozzle.
  • Figures 3A and 3B correspond respectively, as in Figures 1A and 1B, to a rest position and a working position.
  • the same elements as in the previous figures are designated by the same references.
  • the nozzle 10 is still driven by the hydraulic motor 12, but, unlike the device in FIGS. 1A and 1B, the pulley, designated by the reference 11, is articulated in rotation around the axis A relative to the nozzle 10.
  • a deflection piece 11-1 is integral with the pulley 11. At rest (FIG. 3A), this deflection piece extends parallel to the nozzle 10 from a peripheral zone of the pulley 11, on the side of the cam 26, and comprises a perpendicular part, hereinafter called deflector 11-2, coming in front of the outlet of the nozzle 10.
  • the nozzle 10 comprises a finger 10-2 extending perpendicularly to the nozzle on the side of the deflection piece 11-1.
  • a spring 36 presses between the finger 10-2 and the bottom of a housing of the closure part 11-1.
  • This housing is delimited by the part 11-1 itself and a part, hereinafter abutment 11-3, extending first perpendicularly to the part 11-1 then parallel in the direction of the finger 10-2.
  • the deflection piece 11-1 is permanently biased, by the spring 36, towards a deflection position (visible in FIG. 3A) where the deflector 11-2 is in front of the outlet of the nozzle 10.
  • the deflector 11-2 is in fact such that, rather than closing the nozzle 10, it deflects the jet outside of the tanks 28, that is to say towards the tank of the washing machine, for example perpendicular to the nozzle 10.
  • the nozzle 10 supplies water to one of the tanks 28.
  • a suitable sector of the cam 26 is placed, in the rest position of FIG. 3A, opposite the probe. 22-1, and the motor 12 is fed by opening the valve 16.
  • the nozzle 10 provides a jet of water which is deflected towards the tank by the diverter 11-2, and the nozzle 10 is driven in the direction of the needles d 'a watch by the motor 12.
  • the nozzle 10 drives the part 11-1 by means of the finger 10-2 pressing on the spring 36, so that the deflector 11-2 is always opposite the nozzle.
  • the pulley 11 simultaneously drives the lever 22 towards the cam 26 via the cable 18. To obtain this result, the force of the spring 36 is of course greater than the force of the spring 20 transmitted by the cable 18.
  • the deflection piece 11-1 When the probe 22-1 meets the cam 26, the deflection piece 11-1 is blocked but the nozzle 10 continues to rotate clockwise by compressing the spring 36 with the finger 10-2 until the latter comes into abutment on the stop 11-3. The nozzle 10 thus emerges from the diverter and sends a jet of water to the desired tank 28.
  • Each sector of the cam 26 is chosen to block the deflection piece 11-1 so that the nozzle 10, by disengaging from the deflector 11-2, feeds only the corresponding tank 28.
