Definitions

  • the present invention refers to a device for the selection of washing programs for a washing appliance, in particular, though not exclusively, for an integrally built-in dishwasher.
  • Dishwashers of the so called "integrally built-in" type that must be embedded in unit type kitchen furniture, are usually provided with a frontal covering, generally consisting of a full height covering panel for the access door of the washing tank which has homogeneous aesthetic features with the rest of the kitchen furniture.
  • control panel which typically includes a device for the selection of the operating program
  • the selection of the washing programs is made by means of a knurled dial with axis orthogonal to the door front face.
  • a window in the upper edge of the door allows to reach by hand the cylindrical outer surface of the dial, which bears numerical and symbolic references allowing to visualise the selection being made.
  • two windows are provided, one on the upper edge of the door and another one located on the side edge of the door.
  • the knurled dial can be manoeuvred through the window on the side edge of the door, and the selection being made is visualised through the window on the upper edge of the door.
  • object of the present invention is to provide for a device for the selection of washing programs for an integrally built-in washing appliance, in particular for an integrally built-in dishwasher with a control panel created on the upper edge of the door, that would not give the problems encountered with the aforementioned devices.
  • a device for the selection of washing programs for a washing appliance comprising an access door to a washing tank that is hinged at its lower edge to a frame of said washing appliance, characterised in that it includes a cursor mounted on an upper edge of said door and slidable longitudinally to said upper edge, said cursor controlling a programmer mounted within said frame that, in accordance with a setting of said cursor, determines the execution of a respective predetermined washing program.
  • the dishwasher comprises a frame 1 to be embedded in a space provided for by a kitchen furniture. Inside frame 1 a washing tank 2 is housed. Frame 1 and washing tank 2 have a front opening providing the access to the same washing tank. Said front opening is closed by means of a door 3 hinged to the frame 1 in correspondence of its lower edge 4. The door 3 is frontally coated with a full height covering panel 5. Above the frame 1 lays a worktop 6 belonging to the kitchen furniture. The worktop 6 abuts frontally with respect to the frame 1, in such a way that when the door 3 is close, its upper edge 7 gets totally covered by the worktop 6.
  • a control panel comprising a device 8 for the selection of the dishwasher washing programs.
  • the device for the selection washing programs 8 comprises a cursor 9 that can slide longitudinally to the upper edge 7 in such a way as to allow selection of the requested washing program. Obviously, the cursor 9 can be reached only when the door 3 is at least partially open.
  • the selection device 8 controls a programmer 12 that, unlike in the known solutions, is not located within the door 3, but in a more spacious zone of the dishwasher, as for example inside the frame 1 under the washing tank 2.
  • the program selection made by means of the cursor 9 is conveyed to the programmer 12, that governs the dishwasher operation.
  • a switch is schematically shown comprising a first connection 10 placed on a frontal upper edge of the frame 1 and a second connection 11 placed on an inside wall of the door 3 in correspondence of the upper edge 7.
  • the connections 10 and 11 are kept at a distance and the dishwasher cannot operate.
  • the switch 10, 11 also gets closed and the dishwasher starts working according to the program selected by means of the cursor 9.
  • Figure 2 shows a top view of the region of the upper edge 7 of the door where the device for the selection of the washing programs is housed. For example it provides for a jig 13 comprising indexes 14 which detect the positions where the cursor 9 has to be moved to, in order to select various washing programs.
  • a central index 15 identifies the "STOP" position.
  • Figure 3 refers to a first embodiment of the present invention. It consists of a sectional view of the door 3 according to a plane parallel to the front wall of the same.
  • the device 8 consists of a potentiometric slider, for example of the kind produced and marketed by the firm MOLVENO COMETTI, that, as the position of the cursor 9 changes, varies the resistance between the two power terminals 16, 17 to which the programmer 12 is connected, by means of conducting wires.
  • the latter consists of an electronic circuit capable to detect the resistance between the two terminals 16, 17 and to activate accordingly one of the possible predefined washing programs.
  • Figures 4, 5 and 6 refer to a second embodiment of the present invention.
  • Figure 4 is a sectional view of the door 3 according to a plane parallel to the frontal wall of the same.
  • the device 8 comprises a rack 18, sliding together with the cursor 9, which engages a toothed wheel 19, revolving around an axis 20 that is instead fixedly mounted to the door 3.
  • the toothed wheel 19 is held by a flange 28 extending from a support 29 fixed on the inside surface of the upper edge 7 of the door 3.
  • the toothed wheel 19 is mortised in a shaft 21 of a rotary selector 22, known per se, as for example the "resistive switch" produced and marketed by REMCO.
  • the rotary selector 22 is fixed to the flange 28.
  • the rotary selector 22 has power terminals 25 and 26 that are connected, by means of conductive wires 23, 24, to the programmer 12 housed for example in frame 1, under the washing tank 2 ( Figure 1).
  • the programmer 12 can be electronic, as in the case of Figure 3, or a traditional electromechanical programmer, for example of the kind known on the market as EATON model ECR, or ELBI series 5000 or CROUZET model TMX.
  • a bracket 31 is fixedly mounted to and extends beyond the rack 18 on both sides.
  • the bracket 31 supports, on each side of the rack 18, a lamp 32 (in Figure 4 as a simplification, only the lamp on the left side of the rack 18 is shown), whose lightening is controlled for example by the controller 12.
  • the upper edge 7 of the door 3 provides for windows 33 placed in a regular sequence along the same upper edge 7, in such a way that when the cursor 9 is displaced in one direction or the other, the positions being reached corresponding to the various washing programs is indicated to the user by the lightening of the lamp 32 that gleams through the windows 33. This ensures that the cursor 9 is not left in an intermediate position, which would determine a situation of uncertainty about the washing program to be activated.
  • Figures 7, 8, 9 and 10 refer to a third embodiment of the present invention.
  • the cursor 9 is fixedly mounted to a bracket 34 at both ends of which two levers 35 are hinged that are stressed by respective springs 36 against two abutments 37 integral with the bracket 34.
  • a wheel 38 is revolvingly held by a supporting flange 39 fixed to the door 3.
  • the wheel 38 is mortised on a shaft 40 of a rotary selector 22 of the same type as shown in Figure 5.
  • the shaft extends to engage revolvingly in a hollow extension 41 of the flange 39.
  • a spring 42 is wound that has an extension 43 which goes to engage in a recess created on the cursor 9.
  • the spring 42 stresses the cursor 9 to move to the median position shown in Figure 8.
  • small balls 27 revolvingly housed in respective seats inside the supporting flange 39 reduce the sliding friction of the cursor 9 and bracket 34 assembly with respect to the flange 39.
  • the displacement in one direction or the other of the cursor 9 produces the rotation, by means of either one of the levers 35 that acts on one of the pegs 44, of the wheel 38 in one direction or the other.
  • the displacement of the cursor 9 towards the right causes the clockwise rotation of the wheel 38.
  • the lever 35 on the left, hinged in the bracket 34 but kept in a substantially vertical position by the abutment moves toward the right and acting on the peg 44 drives the wheel 38 in rotation.
  • the spring 42 brings it back to the median position, and the lever 35 returns to the position shown in Figure 7.
