Definitions

  • the present invention relates to a device for water inlet dispensing to a plurality of utilising elements in a washing-machine, specifically a laundry washer comprising a programmer, sensing means for the different washing phases and connecting means from the sensing means to a water dispensing element.
  • the programmer is fastened to the laundry washing-machine cabinet or control panel; subsequently the dispenser cam is assembled in a coaxial manner to the programmer along with the sensor.
  • Said sensor is actuated by the cam profile and according to the set program it determines through mechanical returns water inlet orientation to the various compartments containing the washing agents.
  • cam and sensor are assembled outside the programmer, with the cam suitably keyed on the programmer shaft, whereas the sensor is assembled either on the cabinet or on the control panel.
  • these systems cause some disadvantages, such as the large number of required components, namely the programmer, cam, sensor and fastening means for both the cam and sensor.
  • the aim of the present invention is that of indicating how a device for water inlet dispensing to a plurality of utilising elements can be possibly obtained in a washing-machine, specifically a laundry washer, without the inconveniences of the known state of the art, but rather providing the advantages of low-cost manufacture and easy assembly.
  • the present invention has as its subject a device for water inlet dispensing to a number of utilising elements in a washing-machine, specifically a laundry washer comprising a programmer, sensing means for the different wash phases and connecting means from the sensing means to a water dispensing element, characterised in that said sensing means are integral with the programmer.
  • reference no. 1 refers to a programmer fastened to the cabinet by means of a bracket referred as no. 2.
  • No. 3 refers to a dispenser cam whose profile trend has been designed to match the type of programmer used, specifically according to the functions the programmer can execute and the number of phases foreseen.
  • Said dispenser cam 3 is either overmoulded on the programmer cam package - not shown for simplicity's sake in the figure - or on the programmer shaft 6 and located inside the programmer directly behind the front plate 7 forming the programmer housing.
  • No. 4 refers to a sensor, a section of which referred to as no. 8 is in contact with the dispenser cam profile 3.
  • No. 11 refers to a spring which is used to maintain the sensor constantly in contact with the dispenser cam.
  • Said sensor is pivoted in the place referred to as no. 9 on the front plate 7 forming the programmer housing.
  • the senor 4 is connected to a transmission 5 by means of an articulated joint 10, said transmission 5 being connected to a dispenser feeding water to the compartments containing the washing agents (not shown in the figure, as known for itself).
  • the dispenser cam profile is read by the sensor through a window on the programmer housing, where the profile can be followed up by the sensor.
  • the dispenser cam rotates integrally with the programmer shaft thus transmitting oscillating motions to the sensor through its profile.
  • Said motions transferred by the sensor through transmission 5 to a dispenser usually having the shape of a rotating gun determine its orientation so as to feed water to the various compartments according to the program set by the programmer.
  • the dispenser cam profile can be read both in traction and compression, and the transmission system from the water dispenser to the compartments for the washing agents can be obtained either by a rigid rod, a stiff or flexible wire or other equivalent procedures.
