Definitions

  • the present invention relates to a washing and/or drying machine, as described in the preamble of the enclosed first claim.
  • the machines of the type mentioned are equipped with a control panel in the upper section of the cabinet, where the various controls are located, such as the programmer of the washing cycles, the selectors for the temperature, basket rotation speed, drying time, etc., the eventual buttons for enabling particular functions (e.g. half load, spinning suppression, etc.) and a main power switch (ON/OFF).
  • the various controls such as the programmer of the washing cycles, the selectors for the temperature, basket rotation speed, drying time, etc., the eventual buttons for enabling particular functions (e.g. half load, spinning suppression, etc.) and a main power switch (ON/OFF).
  • the reading and/or selecting of functional commands of the machine, and in particular selecting the desired washing program can result in being difficult; in light of this, therefore, it would be advantageous to supply the washing machine with at least one appropriate light, for illuminating the control panel.
  • the same considerations made with regards illuminating the control panel are also valid for illuminating the interior of the basket of a laundry washing and/or drying machine.
  • the operative sequence of use of the machine in substance requires that the loading of the laundry to washed and/or dried in the basket of the machine, the addition of the washing agents in the relative dispenser and the selection of the desired washing program, by way of selection on the programmer of the machine, have to take place before turning on the machine, which takes place by way of the main power switch (ON/OFF).
  • the present invention is based on the acknowledgement of the aforementioned facts and its purpose is that of indicating a washing and/or drying machine equipped with a light, the switching on of which being independent from the main power switch of the machine.
  • Another purpose of the invention is that of indicating a machine in which the system for switching on such light takes advantage of a pre-existing command means, dedicated to controlling other functions; in light of this, therefore, the purpose of the invention is that of avoiding that the aesthetic appearance of the control panel be modified and/or burdened by the addition of an appropriate command means for switching on the light.
  • a further purpose of the invention is that of indicating a command method on the basis of which the switching on of a light is allowed in a manner which does not implicate any additional operation for the user respect those carried out on machines of the known type.
  • FIG 1 a washing and/or drying machine is schematically represented realised according to the details of the present invention, in particular a front loading laundry washing machine.
  • 1 indicates the cabinet of the machine as a whole
  • 2 indicates its front loading door, which gives access to the basket for the laundry
  • 3 indicates its control panel.
  • the control panel 3 is arranged in the upper part of the cabinet 1 and has a series of commands, from among which:
  • a transparent element of the control panel 3 is indicated, behind which three indicator disks 12 are arranged, each of which being coupled to one of the dials 5, 6 and 7; such disks 12 have appropriate printed script that indicate the various options which can be selected: thus the user can read through the transparent part 11 such printed scripts and rotate the relative dial for selecting the desired washing cycle, the temperature and the spinning speed.
  • dial 5 of the washing cycles programmer is of the type apt at assuming the two following axial functional positions (respectively visible in parts A and B of figure 2):
  • the change from one position to the other is obtained by simply pressing the frontal surface of the dial 5, that has an appropriate kinematic blocking/release system.
  • the other dials 6 and 7 are, on the other hand, in the case illustrated, of the traditional type and therefore protruding (but could obviously be of the same type as the dial 5).
  • Figure 2 illustrates, by way of two schematic sectioned views, the part of the control panel 3 where the programmer of the machine is housed, with the relative dial 5; according to the invention, in such part of the control panel, a light is provided, able to facilitate the selection of the program in the aforementioned cases of poor light, supplied independently from the position of the on/off switch 9 of the machine.
  • the actual timer or programmer is indicated as a whole with 20, that in the illustrated case is of the electro-mechanical type, in itself known, thus not requiring a detailed description;
  • 21 indicates a shaft, which allows, by way of the dial 5, the manual rotation of the internal cam group of the programmer 20 (or the contact setting of an electronic board, in the case of an electronic timer), and thus the selection of the desired washing program;
  • 22 indicates a bistable kinematic system, which allows the shaft 21 to take on two different axial positions, clearly visible in comparing parts A and B of figure 2; such kinematic system 22 therefore allows the dial 5 to take on the two functional positions as described above.
  • Such kinematic system 22 comprises a mobile element having inclined planes and a spiral spring, is of the type in itself known (generally with the name push-push) and widely used on existing washing machines, for allowing the extraction from the control panel 3 of the command dial 5.
  • one of the mentioned disks 12 is indicated, which is integral to the shaft 21 and has a printed script indicating the various programs that can be selected, which the user can consult through the transparent element 11.
  • a light for instance a neon, fixed in the known way to the interior of the control panel 3, behind a shield 24; such shield 24 is realised in a transparent material, or able to refract and/or diffuse the light coming from the light 23, so as to illuminate the printed surface of the disk 12A.
  • a first contact element is indicated, fixed, electrically connected to the phase (L) of the electrical mains; 26 indicates a second contact element, mobile against the push of a spiral spring 27, which is electrically connected, through a conductor 28, to a pole of the light 23; the other pole of the light, not represented, can be connected in an appropriate manner, in a known way, directly to the neutral (N) of the electrical mains.
  • a projection 21A of the shaft 21 maintains the switch, constituted by the contacts 25 and 26 open, in contrast to the action of the spring 27; when on the contrary the dial 5 is brought to the working position (fig. 2, part B), the movement of the shaft 21, and therefore of the projection 21A, allows for the closure of the switch 25-26, as a result of the action of the spring 27, with the consequent switching on of the light 23.
  • the switching on of the light 23 is made possible independently from the functional state of the main switch 9 of the machine (i.e. even when such machine is in the OFF position).
  • FIG 3 with this purpose the simplified electric diagram of the machine according to the invention is illustrated; with L and N the phase and neutral of the electrical mains are respectively indicated, while 30 globally represents the electrical control and actuation circuit of the machine, enclosing the programmer 20 and all the various electrical devices of the machine (motor, pumps, solenoid heating resistance, etc.).
  • connection of the light 23 is such to allow its switching on even in conditions of the main power switch 9 being open, i.e. with no power supply of the circuit 30.
  • the above described system of switching on the light 23 could be applied to a dial, similar to that indicated with 5, provided for the opening of the laundry loading door; in such case, therefore, for the machines which provide for opening the door from the control panel, with the door opening command a simultaneous switching on of a light for the inside the basket could be obtained.
  • a plurality of lights, or light emitters, for illuminating and/or emphasising the various command means of the machine could be provided, or the system for switching on the light or lights could be realised on all the dials (5-7) present on the machine.
